Abstract

The invention discloses an upper pin joint guiding and fixing device for transporting a modularized carriage, which belongs to the technical field of logistics transportation equipment and is applied to a logistics transportation chassis carrying a plurality of groups of detachable carriages. The novel modular car body is difficult to accurately butt joint the pin and the pin hole when the existing modular car body is connected, the steel plate around the hole is easy to scratch, the problem of up-down shaking easily occurs when the car jolts, and the safety of the car is seriously affected. On the basis of supporting and retaining the matching structure of the chassis and the carriage body by the whole body of the automobile girder, the pin and the pin hole are independently or cooperatively arranged through the stop block, the stop block contact surface and the splayed guide plate, so that the pin can be accurately inserted into the hole without manual adjustment in the engagement process of the carriage body, the first detachable carriage body, the second detachable carriage body and the third detachable carriage body are matched and combined at will, the original supporting path of the automobile girder is not changed, the structural stress is reasonable, the operation efficiency and the transportation stability of the engagement of the upper part of the modularized carriage body are greatly improved, and the device has good industrial practicability and popularization value.

Upper pin joint guiding and fixing device for modularized carriage transportation Technical Field The invention relates to the technical field of logistics transportation equipment, in particular to an upper pin joint guiding and fixing device for modular carriage transportation, which is suitable for connecting, positioning and fixing the upper parts of a plurality of groups of detachable carriages on a logistics transportation chassis, and is matched with a chassis bearing, lower sliding frame and upper sliding frame deviation correcting structure of the modular carriage transportation device. Background The applicant has filed before an utility model patent of a modularization carriage conveyer (application number: 202522312915.2, application date: 2025, 10 and 31 days) discloses a logistics transportation chassis structure for carrying a plurality of groups of detachable carriages, and the lower sliding deviation correction and carrying of the carriages are realized through the cooperation of a lower carriage of the chassis and an upper carriage of the carriages, so that the modularized carriage conveyer has the advantages of high transportation flexibility and high space utilization rate, and provides a basic device support for logistics transportation of the modularization carriages. In commodity circulation transportation field, modularization railway carriage or compartment body conveyer is by wide application because of possessing the advantage that transportation flexibility is high, space utilization is high, and multiunit detachable railway carriage or compartment body can link up to be placed in same commodity circulation transportation chassis according to the transportation demand, and the chassis relies on the car girder to realize wholly weighing and bears, and the chassis sets up down the balladeur train, railway carriage or compartment body corresponds the lower part sliding fit and rectifies of realizing railway carriage or compartment body and chassis, for guaranteeing bearing stability, the device all does not add elastic cushion class buffer structure. In order to improve the stability of the overall structure after the connection of a plurality of groups of carriage bodies, the prior art has the obvious technical defects that the upper parts of the carriage bodies are usually provided with ropes for fixation in the industry, manual and tedious operations are needed between the carriage bodies, the front-back and left-right dislocation displacement of the carriage bodies can be caused by road jolting in the driving process, the prior pin joint structure has no targeted anti-drop hole constraint design, the upper fixing effect is lost, the stability and the safety of the transportation of the plurality of carriage bodies are seriously reduced, the prior fixing structure is not provided with accurate guide assemblies, the stop block abutting structure is not combined for fixing and limiting, the prior art cannot adapt to the arbitrary connection and combination requirements of a plurality of groups of detachable carriage bodies, and the universality is poor. The modular carriage body conveying device is used as a basic conveying device, the technical short plate fixed at the upper part is also used, only the lower part of the carriage body and the chassis are matched and positioned, and the special pin joint guiding and stabilizing limiting structure is not designed for the upper part connection between the carriage bodies, so that the problems that the pin is difficult to enter the hole and the carriage body jolt and shift are not solved in the actual modular carriage body connection conveying process, and the basic conveying device becomes a key limiting factor for further improving the operation efficiency and the conveying safety. At present, the positioning structure for connection of the carriage body in the prior art is lack of accurate guiding design, pin and pin hole limiting constraint for jolt displacement is avoided, the carriage matching structure of the chassis and the carriage body is not combined for upper positioning optimization, the matched stop block and stop block contact surface abutting structure is not designed, the problems that the pin is difficult to enter the hole and easy to drop the hole cannot be fundamentally solved, and the high requirements for the connection efficiency and the transportation stability of the modularized carriage body in the logistics transportation field are difficult to meet. Therefore, the design of the upper pin joint guiding and fixing device capable of realizing accurate pin hole and forming stable constraint on pin hole cooperation becomes a key for improving the operation efficiency and the transportation safety of the modularized carriage transportation device. Disclosure of Invention The invention aims to overcome the defects of the prior art, and provides an upper pin joint guiding and fixing device for modular carriage trans
