Lifting driving mechanism and lifting system for high-barrier truck canopy

Abstract

The invention discloses a high-barrier truck cover lifting driving mechanism and a lifting system, the lifting driving mechanism comprises a speed reducer, a driving shaft and a driving chain wheel, the driving shaft is connected with the speed reducer, the driving chain wheel is arranged on the driving shaft, the high-barrier truck comprises a carriage, the carriage comprises a bottom plate, and the driving shaft is rotatably arranged below the bottom plate; the lifting system comprises a canopy, a front lifting upright post, a rear lifting upright post and a lifting driving mechanism, upright post guide rails for guiding the front lifting upright post and the rear lifting upright post are arranged on the carriage, and the front lifting upright post and the rear lifting upright post are respectively lifted under the action of a front transmission mechanism and a rear transmission mechanism. And at least one group of middle lifting upright posts and middle upright post rails for guiding the lifting of the middle lifting upright posts are also arranged in the middle of the carriage. According to the invention, the structure is simple, hidden lifting transmission is adopted from bottom to top, from outside to inside and from the rear part to the front part of the carriage, long-distance transmission is realized, no exposed part exists, the transmission is reliable, flexible and changeable, the price is low, and the use cost of a user is greatly reduced.

Description

technical field [0001] The invention relates to a lifting driving mechanism and a lifting system of a high-bar freight car cover, belonging to the technical field of transport vehicles. Background technique [0002] High-rail transport trucks are also called warehouse trucks. The facades on both sides of the chassis of the warehouse trucks are flower-basket frame structures. Responsible for the main task of road transportation, it is one of the important transportation vehicles in the field of logistics. [0003] High-rail trucks generally encounter a problem that is difficult to overcome and must be faced in the use of loading and unloading goods. Because the goods contained in high-rail trucks are often uneven, and the cabin itself is relatively large, it is necessary to use awnings before transportation. The goods can only be transported after the tarpaulin is covered, but the process of unfolding, covering and storing the tarpaulin is laborious and laborious, and the op...

AI Technical Summary

Problems solved by technology

[0003] High-rail trucks generally encounter a problem that is difficult to overcome and must be faced in the use of loading and unloading goods. Because the goods contained in high-rail trucks are often uneven, and the cabin itself is relatively large, it is necessary to use awnings before transportation. The goods can only be transported after the tarpaulin is covered, but the process of unfolding, covering and storing the tarpaulin is laborious and laborious, and the operation is not safe. On the canopy rod, the height is fixed. When the truck loads and unloads large or special-shaped goods, the canopy cannot be raised to give way, which is very troublesome, and even cannot be shipped. Cars go away, increasing the transportation cost of the cargo owner and wasting transportation resources

[0004] In addition, most of the vehicles use forklifts when loading and unloading goods, and the many canopy poles on the top of the existing carriages are all inserted into the corresponding flower racks. When the forklift lifts the goods, they cannot be lifted and can only be moved manually. Labor cost

[0005] Although the existing electric lifting tarpaulin can realize the automatic lifting of the tarpaulin, its structure is not only complicated, but also the cost is high, and the electrical control system is prone to problems. During the use process, the tarpaulin will not move or the lifting will not be in place. Therefore, there is a need for a high-bar truck canopy rod lifting drive mechanism and a lifting system that is simple in structure, low in cost, and can meet the synchronous lifting requirements of the canopy support.
