Description

A mortar hopper lifting and translation device for tunnel boring machines Technical Field

[0001] This utility model belongs to the technical field of tunnel construction auxiliary equipment, specifically, it relates to a mortar tank lifting and translation device for a tunnel boring machine. Background Technology

[0002] With the continuous development and progress of my country's subway industry, the excavation depth of tunnel boring machines (TBMs) has further increased, and the probability of passing through the underground parts of buildings has gradually increased. Because traditional TBMs have relatively low grouting pressure, issues such as ground subsidence and water seepage in load-bearing and non-load-bearing walls arise, directly affecting the deformation of surface structures and the strength of load-bearing and non-load-bearing walls. After the TBM removes the soil layer in front, concrete mortar needs to be injected promptly to ensure the quality of tunnel formation.

[0003] During the construction of full-face hard rock tunnel boring machines (TBMs), timely shotcreting is required to stabilize the excavated rock mass. Mortar is loaded into containers outside the tunnel and towed to a designated location by a locomotive. Then, a mechanical device lifts the mortar container and places it at the working position for use. Once the mortar is used up, it is moved from the working position to a mining car and towed away to make room for a new mortar container. Due to limitations imposed by the type of trailer and the weight of the mortar containers, the mortar container lifting or moving mechanical devices lack versatility and have long transfer times, making it difficult to meet the mortar supply needs and affecting tunneling efficiency. Therefore, a highly adaptable TBM mortar container lifting and moving device is needed to meet the hoisting requirements of TBMs in tunnel construction. Summary of the Invention

[0004] The purpose of this invention is to provide a highly adaptable lifting and translation device for the mortar tank of a tunnel boring machine (TBM) that meets the requirements for hoisting the mortar tank in tunnel construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mortar tank lifting and translating device for a tunnel boring machine includes a movable support, a translating frame, a mounting plate, a hoisting mechanism, and a translating mechanism. The translating frame is mounted on the movable support, the mounting plate is set on the translating frame, the hoisting mechanism is mounted on the mounting plate, and the translating mechanism is mounted on the translating frame and provides translational force to the translating frame.

[0007] The translation frame includes a first crossbeam and a second crossbeam arranged opposite each other, with several support beams between the first and second crossbeams. The translation mechanism includes two first translation wheels, two second translation wheels, a first translation track, a second translation track, a first translation motor, and a second translation motor. The first and second translation tracks are arranged opposite each other on the movable support. The two first translation wheels are respectively located at both ends of the first crossbeam, and the two second translation wheels are respectively located at both ends of the second crossbeam. The first translation wheels are located on the first translation track, and the second translation wheels are located on the second translation track. The first translation wheel at the right end of the first crossbeam is connected to the first translation motor through a first translation reducer, and the second translation wheel at the left end of the second crossbeam is connected to the translation motor through a second translation reducer.

[0008] The lifting mechanism includes a left lifting assembly and a right lifting assembly. The left and right lifting assemblies have identical structures, each including a lifting motor, a lifting reducer, a front bearing housing, a rear bearing housing, a front drum shaft, a rear drum shaft, a front drum, a rear drum, a front wire rope, a rear wire rope, a front hook, and a rear hook.

This application uses four hooks in conjunction with the mortar tank lifting lugs to lift the mortar tank, which can be applied to mortar tanks of different diameters. Then, the mortar tank is moved by the translation mechanism, which can effectively ensure the mortar pipe lifting work and further improve the lifting efficiency. Attached Figure Description

This application has a simple structure, is easy to operate and facilitates later maintenance. This application uses four hooks in cooperation with the lifting lugs of the mortar tank 42 to lift the mortar tank 42, which can be applied to mortar tanks 42 of different diameters.
