Mechanical guardrail hoisting device for railway construction

Abstract

The invention discloses a mechanical guardrail hoisting device for railway construction. The device structurally comprises an arbor wheel conveying belt, a rotation wheel governor box, an inclined rack handle rod, a plunger hydraulic cylinder, an alloy plunger cylinder, a joint roller wheel, a guardrail clamping plate, a hoisting groove base, a hinge rolling shaft column and a rubber fastening block. The arbor wheel conveying belt is inserted in the right side of the rotation wheel governor box. According to the mechanical guardrail hoisting device, the rotation wheel governor box is providedwith a piston cylinder jacking device, a rotary table conveying mechanism, an intermittent transmission device, a ratchet wheel rotation mechanism, a fan tray pendulum device, a sliding block clash device, an internal combustion cylinder friction device and a rubber pipe clamping mechanism. The guardrail hoisting device conducts hoisting by applying the hydraulic cylinder and controls the rotationspeed of a rotation wheel at the same time to achieve the effect of adjustment, the output rate of a rotation wheel conveying belt can be changed, in cooperation with the self-weights of different guardrails, compression resistance hoisting operation is conducted, by integrally simplifying a mechanical structure, the hoisting process is directly influenced by internal linkage transmission, and the off-road probability is greatly reduced.

Description

technical field [0001] The invention relates to a rail guard lifting device for a railway construction machine, which belongs to the field of railway construction and rail guard lifting equipment. Background technique [0002] Various civil engineering facilities on the railway also refer to the technologies used in various stages of railway construction such as survey design, construction, maintenance, and reconstruction. Railway engineering initially includes civil engineering related to railways such as tracks, roadbeds, bridges, tunnels, and stations. , machinery and signal engineering, the current technology of the guard rail recovery device lacks the telescopic rotation speed regulation of the jack or the piston cylinder, which may easily lead to the early fall of the guard rail during the recovery process, and insufficient control of the pressure and speed during the connection process , so that the smoothness of the overall runner rotation is lacking, and the over-ro...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a railway construction machinery guard rail lifting device to solve the lack of telescopic rotation and speed regulation of the jack or piston cylinder by the guard rail lifting device, which may easily lead to Falling off the track in advance, insufficient control of the pressure and speed during the connection process, resulting in a lack of fluency in the overall runner rotation, and excessive rotation and transmission causing the recovery pressure to bounce off the track, failing to achieve the effect of speed regulation and reducing the connection transmission
