Description

Technical Field

[0001] This utility model relates to the technical field of continuous belt winding devices, specifically to a TBM continuous belt winding device. Background Technology

[0002] TBM (Tunnel Boring Machine) is a high-performance mechanical equipment used for tunnel construction. In the field of tunnel construction, TBM construction technology is being gradually promoted and applied; it can realize the integrated operation of tunnel excavation, support, and muck removal; as the TBM advances forward, the belt storage bin continuously releases belts, allowing the continuous belt conveyor to extend to meet the increasing depth requirements of tunnel construction.

[0003] Regarding muck removal methods in tunnels, there is the traditional diesel locomotive method. However, continuous belt conveyor muck removal is widely used in tunnel construction due to its real-time operation, high transport speed, and high muck removal efficiency. After the TBM equipment completes tunnel excavation and breakthrough, the recovery process of the continuous belt conveyor becomes an important and complex task in the construction process. Because the continuous belt conveyor usually runs through the entire tunnel, its length often reaches several kilometers, and it has a large self-weight. Moreover, it is arranged in narrow tunnels, laid deep and at a high height, so the recovery work faces many challenges.

[0004] In traditional recovery methods, manual operation typically involves cutting and dismantling the conveyor belt segment by segment inside the tunnel, or transporting the dismantled belt to the tunnel exit for external processing. While these methods are common recovery approaches, they are inefficient and pose significant safety risks due to the large amount of manual labor involved, limited working space, and complex transportation and dismantling procedures, making dismantling operations quite difficult. Therefore, how to efficiently and safely recover long-distance, heavy continuous conveyor belts has become a major challenge after the completion of tunnel excavation.

[0005] In the existing technology, the storage method of storing continuous TBM belts in the belt storage bins inside the tunnel has low storage density, wastes storage space in the storage bins, and has a complex storage structure, such as "S"-shaped and "U"-shaped storage belts.

[0006] Therefore, there is an urgent need to introduce a new device to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to solve or alleviate the above-mentioned problems, especially to address the issue of low storage density and wasted storage space in existing TBM continuous belt storage bins within tunnels. This invention proposes a TBM continuous belt winding device. This invention is achieved through the following technical solution: a TBM continuous belt winding device, comprising a first drive device and a second drive device.

[0008] The first drive device and the second drive device each include a frame, on which a reel and a reducer and a motor for driving the reel to rotate are mounted; the frame of the second drive device is also provided with two staggered idlers; during winding, either the first drive device or the second drive device is the first winding unit; when the second drive device is used as the first winding unit, the continuous belt is tensioned by the two idlers and then wound onto the reel of the second drive device; when the reel of the second drive device reaches the maximum winding length, the reel on the first drive device winds the continuous belt on the reel of the second drive device until half of the maximum winding length; when the first drive device is the first winding unit, the continuous belt passes through the frame of the second drive device and is directly wound onto the reel on the first drive device.

[0009] The continuous belt is fixed to a reel mounted on the first drive device or a reel mounted on the second drive device by a dovetail wire.

[0010] The motor is powered on and drives the reducer to rotate, which in turn drives the roller to rotate; two idler rollers are horizontally arranged in the middle of the second drive device, and there is a height difference between the two idler rollers.

[0011] The second drive device has two rollers on its frame, which are not on the same horizontal plane or the same vertical plane.

[0012] Preferably, the relative height difference between the two idlers does not exceed the diameter of the two idlers;

[0013] The first driving device is provided with a pair of vertical limiting rollers; the second driving device is provided with a pair of vertical limiting rollers on each side.

[0014] The vertical limiting rollers on the frame of the first drive device have a spacing between each pair of limiting rollers that is slightly larger than the width of the continuous belt;

[0015] The vertical limiting rollers on the frame of the second drive device have a spacing between each pair of limiting rollers that is slightly larger than the width of the continuous belt.

[0016] The reel is composed of angle steel and steel pipes, and several steel pipes are fixedly connected between the end faces of two angle steels facing each other; the outer layer of the steel pipes is also fixedly connected by several connecting ribs.

[0017] The second drive device is equipped with gears on its spool, reducer, and motor, and the gears are connected by chains.

[0018] The gears on the second drive device have a greater number of teeth on the reducer than on the motor; the gears on the reel have a greater number of teeth than on the motor.

[0019] The first drive device is equipped with two vertical limiting rollers;

[0020] The second drive device has two vertical limiting rollers on each side, for a total of four vertical limiting rollers.

[0021] Preferably, the distance between the two adjacent limiting rollers is slightly greater than the width of the continuous belt; its function is to prevent the belt from deviating during the winding process of the continuous belt.

[0022] Two idler rollers are installed in the middle of the second drive device to tension the continuous belt and reduce frictional resistance during the winding process.

[0023] The spools on the first drive device and the second drive device are fixed by several dovetail threads and a continuous belt; this prevents the spools from slipping and makes them easier to disassemble and assemble.

[0024] The reel is composed of angle steel and steel pipes, and several steel pipes are fixedly connected between the end faces of two angle steels facing each other.

[0025] The outer layer of the steel pipe is also fixedly connected by several connecting ribs.

[0026] The TBM continuous winding device, when winding the continuous belt, first uses the second drive device to wind the continuous belt to the maximum length that can be stored in the hole, then fixes the continuous belt joint on the second drive device to the reel of the first drive device with dovetail wire, and performs a second winding, the winding length being half of the winding length of the continuous belt wound by the second drive device.

[0027] After the first and second drive devices have finished winding, they are bundled into an "eye roll" and then lifted and transported using a crane.

[0028] Preferably, when the winding device is performing a winding operation, the positions of the first drive device and the second drive device can be interchanged, which can improve the flexibility of use and reduce the failure rate of the winding device.

[0029] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0030] 1. The device of this utility model has a simple structure and the required materials are easy to find at the tunnel excavation construction site. It can be sourced locally, is easy to assemble and manufacture, and has low processing and use costs.

[0031] 2. The device of this utility model has a simple structure, a high degree of mechanization in winding continuous belts, and is easy and simple to operate; it has low requirements for the technical level of operators and is easy to promote and apply in the field of tunnel engineering.

[0032] 3. The device of this utility model can save a lot of manual operation and machinery costs, and can be applied on a large scale at a low cost;

[0033] 4. The device of this utility model is equipped with two winding drive devices, which can meet the maximum storage capacity of the continuous belt storage bin in the field of tunnel excavation, greatly reduce the number of joints of the continuous belt, and save a lot of time for the subsequent continuous belt vulcanization process.

[0034] 5. The device of this utility model can increase storage density and effectively utilize space by winding and storing continuous belts. By using two reels of the first and second drive wheels to each wind up half of the continuous belt, compared with winding a predetermined length of continuous belt with a single reel, the diameter of the wound continuous belt of the predetermined length is greatly reduced. The beneficial effects are that it can not only save the height required for the belt storage bin in the tunnel, but also reduce space waste by winding it into an "eye roll" and binding it. Furthermore, when using a crane for lifting, the symmetry of the "eye roll" can avoid the center of gravity shift and reduce transportation risks. The structure of the "eye roll" is stable after binding, which is more conducive to the balance during lifting. It reduces the difficulty of lifting, increases the stability of lifting, and greatly reduces the safety risks in the field of tunnel excavation.

[0035] 6. In this utility model, the positions of the first driving device and the second driving device can be interchanged. Especially in the limited space of tunnel excavation, this greatly improves flexibility. Operators can flexibly adjust the position of the winding device according to different working environments to ensure that tunnel operations can proceed normally. It can also avoid overloading of a certain winding device, achieve load balance, reduce overloading of a certain winding device, reduce the possibility of winding device failure, extend the service life of the winding device, and improve system stability.
