Description

Back door and bumper ground protection device for bulk material vehicle carriage Technical Field The utility model relates to the technical field of unloading devices, in particular to a ground contact protection device for a rear door and a bumper of a bulk material vehicle carriage. Background Bulk material trucks (such as dumper, mining car and the like) need to open the carriage back door when unloading after stopping on the hydraulic turning plate, and in the use process, because operators observe carelessly, the vehicle bumper or the vehicle door is easy to touch the ground, the vehicle generates a lever principle, and the rear wheel is tilted, and even the vehicle falls off from the hydraulic turning plate when serious, so that larger economic loss is generated. The traditional rear door ground contact protection device adopts a rigid support or hydraulic buffer structure, and the structure has the following problems: 1. the rigid supporting device is easy to deform or wear the rear door due to uneven ground; 2. The hydraulic buffer structure has high cost and complex maintenance, and is easy to leak oil and lose efficacy after long-term use; 3. The existing spring buffer device has insufficient elastic travel and is difficult to adapt to different ground working conditions. Therefore, there is a need for a ground contact protection device that is simple in structure, low in cost, and durable, and is intended to improve the safety and operational reliability of the device, and reduce the risk of human error. Disclosure of utility model The utility model aims to overcome the technical defects, and provides the ground contact protection device for the carriage rear door and the bumper of the bulk material vehicle, which can timely stop the lifting of the hydraulic turning plate by absorbing impact force, protect the carriage rear door and the bumper and reduce maintenance cost. The technical scheme adopted for achieving the technical purpose is that the ground contact protection device for the rear door of the bulk material vehicle carriage and the bumper comprises a fixed plate and a swinging frame, wherein one end of the fixed plate is provided with a hinged hanging lug, the other end of the fixed plate is provided with a through hole, and a first shaft hole is formed in the hinged hanging lug; The fixed plate lower surface is equipped with the spring hangers, be equipped with the stand on the swing frame, be equipped with the regulating spindle on the stand, the spring hangers with be equipped with the spring between the regulating spindle on the swing frame the stand front side still is equipped with photoelectric support be equipped with photoelectric sensor on the photoelectric support. Preferably, the swing frame is of a U-shaped structure and comprises a front support and a rear support which are symmetrical to each other, the swing rod is arranged at the left ends of the front support and the rear support, a first rib plate and a second rib plate are further arranged between the front support and the rear support from left to right in sequence, and the upright post is arranged on the first rib plate. Preferably, the upper end of the upright post is fixed with the first rib plate, the lower end of the upright post is provided with an adjusting groove, and the adjusting shaft penetrates through the adjusting groove. Preferably, the adjusting groove is of a zigzag structure. Preferably, the front bracket and the rear bracket are both L-shaped structures and comprise a horizontal part and a vertical part, and the horizontal part and the vertical part are in arc transition connection. Preferably, the top end of the horizontal part is of a stepped structure and comprises a first step and a second step. Preferably, the swing rod is arranged at the top end of the first step, and the fixing plate is arranged above the second step. Preferably, the fixed plate is an I-shaped structure and comprises a left end plate, a middle connecting rod and a right end plate, the through hole is formed in the left end plate, the spring hanging lugs are arranged on the middle connecting rod, and the hinged hanging lugs are arranged on the right end plate. The utility model has the beneficial effects that the fixed plate, the swinging frame, the spring and the photoelectric sensor are matched to work, so that the ground contact protection of the carriage back door and the bumper is realized, the hydraulic turning plate is controlled to stop working in time after the back wheel is tilted, and the situation that a vehicle falls from the hydraulic turning plate and generates larger economic loss is avoided.
