Description

Equipment for carrying silk truck Technical Field The invention relates to the technical field of automatic guided vehicles, in particular to equipment for carrying a wire barrow. Background The utility model patent with the bulletin number of CN223254027U discloses a wire car carrying device, which realizes automatic hooking and separation with a wire car front side transverse bar by arranging a latch hook mechanism and a driving mechanism at the front side of an Automatic Guided Vehicle (AGV). In order to improve the precision and stability of the butt joint process, the device is also specially provided with a damping mechanism, wherein the damping mechanism comprises a damping block capable of transversely moving and a guide spring for providing elastic restoring force for the damping block. When the automatic guide vehicle approaches to the wire transporting vehicle, the shock absorption block firstly contacts with the side surface of the cross bar, and the guide spring is compressed to absorb collision energy, so that buffering and pre-positioning are realized, and conditions are provided for accurate hooking of the follow-up lock hook. However, during long term use, the guide spring may undergo multiple "compression-rebound" stress cycles. In continuous operation, the spring material undergoes microstructure damage accumulation due to long-term alternating load, which results in irreversible degradation of macroscopic properties, in particular in a reduced spring rate, a reduced free length, a reduced restoring force and an increased hysteresis. The performance attenuation can directly cause the buffer stroke of the damping mechanism to become unstable, the pre-positioning datum point to drift, and finally the butting precision and reliability of the latch hook mechanism are affected. Therefore, the existing wire cart handling device is still to be improved. Disclosure of Invention Aiming at the defects of the prior art, the invention provides equipment for carrying a wire barrow, which can reduce the loss of a guide spring when the wire barrow is abutted against a damping mechanism, thereby prolonging the use effect and the service life of the guide spring. In order to solve the technical problems, the invention is solved by the following technical scheme: The equipment for carrying the wire barrow comprises an automatic guide barrow, a fork arranged on the front side of the automatic guide barrow and damping mechanisms arranged on two sides of the fork, wherein each damping mechanism comprises a base arranged on the fork, a damping block arranged on the front side of the base, a guide spring arranged between the damping block and the base so that the damping block has a trend of being transversely far away from the base, a supporting roller rotationally arranged on the front side of the base, an elastic buffer layer arranged on the outer peripheral surface of the supporting roller, and an avoidance groove formed in the damping block and used for the roller to transversely extend out; When the elastic buffer layer is propped against the front side of the wire trolley and the fork is lifted, the interval between the fork and the bottom of the wire trolley is closed so that the supporting roller rolls on the front side of the wire trolley; The device comprises a support roller, a detection unit, a controller, an oiling device, a control signal processing unit and a control signal processing unit, wherein the detection unit is used for detecting the rotation times of the support roller to output a detection signal, the detection unit is coupled with the controller which is used for receiving the detection signal and outputting the control signal, the controller is coupled with the oiling device which responds to the control signal, and a time threshold value is preset in the controller; when the detection unit detects that the rotation times of the supporting roller are larger than the times threshold, the oiling device injects lubricating grease into the guide spring to lubricate the guide spring. By adopting the scheme, when the silk car extrudes the snubber block on the snubber block, the snubber block can cushion under the elasticity effect of guide spring, and the backing roll stretches out from dodging the inslot simultaneously to support the front side of pressing in the silk car through elastic buffer layer, thereby compensate, in order to reduce the impact force to guide spring, thereby prolong its life. When the damping mechanism is lifted along with the fork, when the gap between the fork and the bottom of the wire trolley is closed, the damping block can generate longitudinal friction with the front side of the wire trolley, and at the moment, the sliding friction between the damping block and the wire trolley can be converted into rolling friction due to the fact that the supporting roller is used as a main stress part, so that the radial stress of the guide spring is reduced, and the serv
