Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to an auxiliary assembly tool for a main drive wear-resistant steel belt of a TBM. Background Art

[0002] The TBM main drive system is called the "heart" of the shield machine, and the main drive seal is the "diaphragm of the heart". As the core component of the TBM, the main drive seal has the function of preventing mud, water, sand and gravel and other substances from penetrating into the main drive. Among them, the wear-resistant steel belt in the TBM main drive seal is crucial. The wear-resistant steel belt is usually made of special materials with extremely high wear resistance, the purpose is to extend the service life of the main drive seal. Once the wear-resistant steel belt is severely worn, the main drive seal will fail, and mud, water, sand and gravel and other substances will enter the main drive, damaging the main bearings, pinions and other components inside the main drive, thereby hindering the construction progress and increasing the project cost. In serious cases, it may also cause the entire construction work to be unable to be completed on schedule.

[0003] The inner and outer sealed wear-resistant runways of the TBM main drive are formed by welding wear-resistant steel strips. According to the diameter of the inner and outer sealed wear-resistant runways, multiple sections of wear-resistant steel strips are welded end to end to form a circular ring, and then the whole is mounted on the inner and outer sealing support rings. The existing technology for assembling wear-resistant steel strips is to distribute a number of operators around the circumference of the wear-resistant steel strip. The operators hold a roasting gun and heat the wear-resistant steel strip with a flame at the same time to heat the wear-resistant steel strip to expand it. During the heating process, the operators must use pliers to clamp the upper edge of the wear-resistant steel strip. Multiple people work together to mount the wear-resistant steel strip on the support ring. This method not only consumes a lot of manpower, but also requires personnel to always clamp the wear-resistant steel strip during the heating process. The operators are at risk of being burned, and the labor intensity of the workers is high. Summary of the invention

[0004] In order to solve the problem that it is inconvenient to put the wear-resistant steel belt onto the support ring in the prior art, which is time-consuming and labor-intensive, the utility model provides a TBM main drive wear-resistant steel belt auxiliary assembly tool, which can quickly and efficiently assemble the wear-resistant steel belt onto the support ring, saving time and effort; and has strong versatility, can be suitable for the assembly of wear-resistant steel belts of different diameters, and can reduce the risk of burns to operators.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a TBM main drive wear-resistant steel belt auxiliary assembly tool, including a cylindrical base and a circular base, a lifting lug is fixedly arranged on the cylindrical base, and a plurality of rectangular tubes are arranged in an annular shape between the cylindrical base and the circular base, and one end of the rectangular tube is connected to the cylindrical base and the other end is connected to the circular base. The lifting lug is used to facilitate the crane to lift and move the auxiliary assembly tool, and the rectangular tube is used to connect the cylindrical base and the circular base. Through the cooperation of the rectangular tube and the cylindrical base, the rectangular tube can be adjusted to a certain angle so as to connect circular bases of different specifications, thereby being suitable for the wear-resistant steel belts required to be set with different specifications and diameters.

[0006] A plurality of screws are arranged in a ring shape on the side wall of the circular ring base, and each of the screws is provided with a steel belt clamp, which is located outside the circular ring base. The distance between the steel belt clamp and the circular ring base can be directly adjusted by the screw, and the position of the steel belt clamp on the screw can be adjusted, thereby adjusting the distance between the steel belt clamp and the circular ring base, so that the auxiliary assembly tool is adapted to the required set of wear-resistant steel belts, and the steel belt clamp plays the role of clamping the wear-resistant steel belt.

[0007] Furthermore, a supporting circular plate is fixedly arranged inside the cylindrical base, and the lifting ear is fixedly arranged at the top center position of the supporting circular plate, and the supporting circular plate is used for installing and assembling the lifting ear.

[0008] Furthermore, the outer wall of the columnar base is provided with a plurality of first hinge seats in a ring shape, the top of the circular base is provided with a plurality of second hinge seats in a ring shape, the upper end of the rectangular tube is hinged to the first hinge seat, and the lower end is hinged to the second hinge seat.

[0009] Furthermore, a plurality of threaded holes are arranged in an annular pattern on the side wall of the annular base, and the screw is threadedly connected to the annular base through the threaded holes, so as to facilitate adjustment of the spacing between the steel belt clamp and the annular base.

[0010] Furthermore, the steel belt clamp includes a U-shaped plate, an adjusting nut and an adjusting bolt. A connecting rod is arranged on the top of the U-shaped plate. The adjusting nut is fixedly arranged on the top of the connecting rod and is threadedly connected to the screw rod. The position of the steel belt clamp on the screw rod is adjusted by the nut.

[0011] Furthermore, the adjusting bolt is arranged on one side of the U-shaped plate, one end of the adjusting bolt extends into the U-shaped plate and is fixedly connected with a tightening circular plate, and the effect of clamping the wear-resistant steel belt is achieved through the cooperation between the adjusting bolt and the U-shaped plate.

[0012] Through the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The utility model has a simple structure and is easy to operate. It can quickly and efficiently assemble the wear-resistant steel belt to the support ring, saving time and effort. It has strong versatility and can be applied to the assembly of wear-resistant steel belts of different diameters. The method of clamping the wear-resistant steel belt by a mechanical structure can avoid cross-operation of personnel. During the process of heating the wear-resistant steel belt by the operator, the operator only needs to heat the wear-resistant steel belt, which replaces the operation of the operator always clamping the wear-resistant steel belt in the traditional assembly operation, reducing the risk of scalding the operator caused by the high temperature caused by heating the wear-resistant steel belt.

[0014] 2. The utility model connects the column base and the circular ring base through a rectangular tube. By adjusting the angle of the rectangular tube, circular ring bases of different sizes can be connected to achieve the assembly of wear-resistant steel belts suitable for different diameters.

[0015] 3. The utility model can directly adjust the distance between the steel belt clamp and the circular ring base through the screw rod, and can adjust the position of the steel belt clamp on the screw rod, thereby adjusting the distance between the steel belt clamp and the circular ring base, so that the auxiliary assembly tool is adapted to the required set of wear-resistant steel belts.

[0016] 4. The steel belt clamp of the utility model plays the role of clamping the wear-resistant steel belt, wherein the purpose of adjusting the position of the steel belt clamp on the screw rod is achieved through the nut, and the effect of clamping the wear-resistant steel belt is achieved through the cooperation of the adjusting bolt and the U-shaped plate. The tightening circular plate is used to increase the contact area between the adjusting bolt and the wear-resistant steel belt, thereby improving the clamping effect of the adjusting bolt on the wear-resistant steel belt.
