Flexion and extension device based on directional wheel strip meshing transmission and using method

Abstract

The invention discloses a flexion and extension device based on directional wheel strip meshing transmission and a using method. A gantry support is fixed to a base, a groove penetrating to the two ends of each flexion and extension body is formed in the bottom of each flexion and extension body, and a first rack is fixed to the bottom of one side of each flexion and extension body in the groove extending direction. A plurality of positioning holes are formed in the side wall of the other side of each flexion and extension body along the extension direction of the grooves. The first flexion and extension body is connected to the gantry support in a sliding mode, the first flexion and extension body is connected into a groove of the first flexion and extension body in a sliding mode, and soon, the nth flexion and extension body is connected into a groove of the n-1th flexion and extension body in a sliding mode. Driving devices are arranged on the base in a sliding mode, first gears are connected to output shafts of the driving devices, and the first gears can be meshed with first racks on any flexion and extension body. Fastener containing boxes and screwing devices are fixed to the base, the screwing devices are located on the sides, provided with positioning holes, of the flexion and extension bodies, the fastener containing boxes are located between the screwing devices andthe flexion and extension bodies. The flexion and extension transmission effect of the flexion and extension device based on the directional wheel strip meshing transmission and the using method is better.

Description

technical field [0001] The invention belongs to the field of structural design of a transmission system of a flexion and extension device, and in particular relates to a flexion and extension device and a use method based on meshing transmission of directional wheel bars. Background technique [0002] In the field of conventional construction machinery, long-distance flexion and extension devices have broad application prospects. A good and efficient transmission of flexion and extension devices will effectively ensure the stability and effectiveness of the output body. In the existing transmission mechanism, the mechanical structure system that can flex and extend for a long distance Relatively small. [0003] Among the existing telescopic devices, some schemes realize the expansion and contraction by aligning the synchronous belt, some realize the expansion and contraction through the hydraulic transmission, and some realize the contraction through the progressive construc...

AI Technical Summary

Problems solved by technology

First of all, the expansion and contraction is realized through the alignment of the timing belt. The biggest problem is that the force of the timing belt is poor, and the connection points of each timing belt are not strong enough, which will easily cause the output of the telescopic device to break and bend suddenly at a long distance. ; Secondly, the cost of hydraulic transmission is relatively high, and the supporting construction of the transmission is large, which is not economical for engineering construction; finally, the progressive construction method through scaffolding is the traditional telescopic method, which has low telescopic efficiency and high labor construction costs.
