Description

Technical Field

[0001] The utility model relates to the technical field of electric forklifts, and specifically relates to a bridge structure of an electric forklift. Background Art

[0002] The upper shaft vehicle is a commonly used equipment in the workshop. Using the upper shaft vehicle to move the warp beam to the loom is time-saving and labor-saving. However, when the upper shaft vehicle is running, if the ground is uneven, it will tilt on one side. The existing one only installs the driving wheels and universal wheels on the flat plate, and does not perform dynamic balance, resulting in difficult operation for people, difficult steering during the vehicle walking process, and easy to cause accidents. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In view of the deficiencies of the prior art, the utility model provides a bridge structure of an electric forklift, which solves the problems raised in the above background art.

[0005] (2) Technical Solutions

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A bridge structure of an electric forklift includes a bridge structure, and the bridge structure includes a bridge support frame bottom plate, the bridge support frame bottom plate can be installed in the electric forklift, a bridge support frame side plate connected to the bridge support frame bottom plate is arranged in the bridge support frame bottom plate, a bridge structure welding part connected to the bridge support frame side plate and capable of adjusting the angle for rotation is arranged in the bridge support frame bottom plate, a universal wheel is arranged in the bridge structure welding part, a driving wheel is arranged in the bridge structure welding part, and the angles of the universal wheel and the driving wheel can be adjusted through the bridge structure welding part.

[0007] Furthermore, the bridge support frame side plates are symmetrically arranged at the bottom of the bridge support frame bottom plate, and a through shaft capable of being inserted into the bridge support frame side plates is arranged at the bottom of the bridge structure welding part.

[0008] Furthermore, the bridge support frame side plates are connected to the bridge support frame bottom plate by screws, bearings in contact with the through shaft are respectively arranged at both ends of the bridge structure welding part, hole snap rings capable of limiting the bearings are further arranged at both ends of the bridge structure welding part, and shaft snap rings capable of being embedded into the through shaft are arranged in the hole snap rings.

[0009] Furthermore, both ends of the through shaft are respectively connected to two bridge support frame side plates.

[0010] Furthermore, a universal wheel is arranged at the front end of the bridge structure welding part, and a driving wheel is arranged at the rear end of the bridge structure welding part.

[0011] Further, a positioning and locking block for positioning and locking the universal wheel is provided at the front end of the bridge structure welding part, and the universal wheel is locked and fixed in the positioning and locking block by bolts. A positioning through hole for positioning the driving wheel is provided at the rear end of the bridge structure welding part, and the driving wheel is inserted into the positioning through hole and can be locked by bolts.

[0012] Further, the width of the universal wheel is smaller than the width of the driving wheel.

[0013] It is installed at the designated position of the electric axle truck through the bottom plate of the bridge support frame. During operation, the electric axle truck is manually operated to move forward. When passing through some areas with uneven ground, the universal wheel and the driving wheel may have a situation where one side cannot contact the ground. However, due to the weight of the vehicle body itself (if transporting axles or cloth rolls, there is also the weight of the axles and cloth rolls), the gravity will press on the bridge mechanism. At this time, the end that cannot contact the ground will rotate through the bearing on the through shaft of the bridge mechanism, and then contact the ground. This movement is carried out in real time as the electric warp beam truck continues to move forward, realizing real-time dynamic balance, so that the electric axle truck can run stably and balanced on uneven ground.

[0014] Compared with the prior art, for the bridge mechanism of this electric handling vehicle, the gravity of the vehicle body itself, the axle weight, and the cloth roll weight press on the bridge mechanism. If the ground is uneven, the bridge structure will rotate left and right through the middle rotating shaft, so as to realize the dynamic balance of the handling vehicle.
