Integral slag dumping workbench for dumping the slag in the cabin of the slag truck in the tunnel

Abstract

The invention discloses an integral slag turning workbench for dumping slag in a compartment of a slag transporting vehicle in a tunnel, and belongs to the technical field of tunnel construction equipment. The technical scheme main points of the invention are that the integral slag turning workbench includes base assemblies, horizontal sliding members, big arms, telescopic arms, telescopic arm outer sleeves, upper gripper side plates, an upper gripper connecting beam, an upper gripper longitudinal beam, a flow guiding groove, oil cylinder fixing bases, big arm stretching oil cylinders, big armrotating oil cylinders, upper gripper rotating oil cylinders, lower gripper rotating oil cylinder, lower gripper telescopic oil cylinders, track limit assemblies, a hydraulic system and an electricalsystem. The integral slag turning workbench of the invention is an integral control console, is simple and convenient in operation and improves the construction efficiency. The compartment of the slag transporting vehicle does not need to be lifted as a whole, the risk of falling objects from high altitude does not exist, and the safety of work is improved. All slag unloading operations are completed at the bottom of a shaft well, which does not pollute urban environment. The integral slag turning workbench of the invention is arranged at the bottom of the shaft well, does not require additional ground space, and reduces the occupation of the construction site.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and specifically relates to an integral slag dumping workbench for unloading the slag soil in the compartment of the slag transport truck in the tunnel. It is a device for dumping the dregs in the compartment of the dregs truck to the dregs pit during the process of transporting the dregs truck to the outside of the cave. Background technique [0002] At present, during the construction of the subway tunnel, the slag truck needs to be transported to the steel rail at the bottom of the shaft by a traction locomotive, and the special slag unloading spreader is used, and the lifting hook of the special slag unloading spreader and the slag truck compartment are lifted by the gantry crane. After the shaft is connected, lift the slag truck compartment out of the shaft and transport it to the waste dump; then connect it to the overturn shaft of the slag truck compartment through th...

AI Technical Summary

Problems solved by technology

[0004] 1. The construction efficiency is low. Generally, the depth of the subway shaft is 20-30m. After lifting the slag truck compartment to the ground, it is transported to the slag yard to unload the slag, and then put the slag truck compartment into the slag truck chassis again.

The entire slag unloading time is greatly affected by the depth of the shaft and the location of the slag yard; and the slag truck needs to occupy the gantry crane, so that the segment hoisting and the slag truck unloading must be carried out alternately, which takes up construction time;

[0005] 2. There are potential safety hazards. The compartment of the slag transporter needs to be lifted vertically in the shaft. If the slag transporter compartment overflows with too much slag or the outer surface of the compartment is sticky with easy-to-fall slag, it will affect the personal safety of the construction workers at the bottom of the shaft. Safety;

[0006] 3. It is easy to cause environmental pollution. When the slag truck compartment is dumped, the distance between the compartment and the ground is high, which is likely to cause dust or slag splashes, causing certain pollution to the surrounding environment;

[0007] 4. It affects the planning of the construction site. At present, most of the subway construction is in the city center, the construction site is limited, and the design of the size of the slag site has a great impact on the planning of the construction site.
