[0039] Example

[0040] like Figure 1 As shown, a steel belt track provided by the present invention includes a straight-side track 1, a steel belt joint 2 and a connecting mechanism 3, one end of the straight-side track 1 is connected to one end of the steel belt joint 2. Specifically, holes evenly arranged along the long side direction can be opened on one end of the straight-side track 1 and the end corresponding to the steel belt joint 2, and then the straight-side track 1 and the steel belt joint 2 overlapped together by screws 9 are fixedly connected, the other end of the straight-side track 1 is connected to the other end of the steel belt joint 2 through the connecting mechanism 3 to form a circular track, and the connecting mechanism 3 is used to install the steel belt track on pipes of different diameters by connecting to different positions on the steel belt joint 2.

[0041] The connecting mechanism 3 includes a cushion block 7, a pull rod 5 and a hinge seat 4 connected in sequence. The pull rod 5 is connected to the end axis of the hinge seat 4. The cushion block 7 can also be fixed to the end position of the straight-edge track 1 by means of a screw 9. The connecting mechanism 3 also includes a convex block 6 arranged on the steel belt joint 2. The convex block 6 includes a protrusion 61. The hinge seat 4 is provided with a strip groove 41 matching the protrusion 61. The convex block 6 fixedly installed on the steel belt joint 2 and the cushion block 7 fixedly installed on the end of the straight-edge track 1, as well as a connecting rod and a hinge seat 4 connected to the cushion block 7 in sequence, and then the strip groove 41 on the hinge seat 4 and the protrusion 61 on the convex block 6 are matched and connected to realize that the steel belt joint 2 and the straight-edge track 1 are fixed to the outer periphery of the pipeline to form an arc track. This connection method is quick and convenient. It only needs to embed the protrusion 61 into the strip groove 41 on the hinge seat 4 to complete the overlap fixation. Figure 4 As shown, two rows of positioning holes 21 are provided on the steel belt joint 2, and the positioning holes 21 are evenly spaced along the circumference of the steel belt joint 2. By fixing the convex block 6 on the positioning holes 21 at different positions and changing the circumferential distance between the convex block 6 and the hinge seat 4, it can be suitable for installation on pipes of different diameters. The end of the hinge seat 4 away from the pull rod 5 is also penetrated with a pre-tightening bolt 8 for fastening the hinge seat 4 and the raised portion 61. In addition, the connecting rod and the hinge seat 4 can be more adapted to the arc structure of the outer circumference of the pipeline by means of shaft connection. The strip groove 41 provided on the hinge seat 4 and the raised portion 61 on the convex block 6 are matched and connected, and then the hinge seat 4 can be quickly put on the convex block 6 by means of shaft connection to achieve quick pre-tightening installation. After the strip groove 41 is put on the raised portion 61, the quick installation is completed, and the tightening is completed by tightening the pre-tightening bolt 8. It is convenient, fast and simple to operate.

[0042] In the above embodiments, one end of the straight-side rail 1 is fixedly connected to one end of the steel belt joint 2, and the other end is pre-tightened and quickly connected to the other end of the steel belt joint 2 through a connecting mechanism 3. Specifically, the connecting mechanism 3 can be connected to different positions on the steel belt joint 2 to be suitable for pipes of different diameters.

[0043] In this embodiment, the tie rod 5 is a threaded tie rod 5, and a threaded through hole 71 matching the threaded tie rod 5 is provided on the cushion block 7. By matching the connected threaded tie rod 5 and the threaded through hole 71, the threaded tie rod 5 is screwed in and out to change the length of the entire connection mechanism 3, which can not only be pre-tightened and quickly installed, but also can be matched and installed on pipes of different diameters. According to the matching method of the threaded tie rod 5 and the threaded through hole 71 on the cushion block 7 and the method of changing the installation position of the convex block 6 on the steel belt joint 2, these two methods can achieve rapid length change to adapt to the installation of pipes of different diameters. At the same time, the length of the entire steel belt track can be roughly adjusted in advance to achieve rapid pre-tightening installation. The length of the entire steel belt track is easy to adjust, and the installation is simple and convenient to operate.

[0044] In this embodiment, a fastening through hole 42 is provided at one end of the hinge seat 4 away from the pull rod 5, and a fastening hole 611 is provided on the raised portion 61 corresponding to the fastening through hole 42. The fastening hole 611 and the fastening through hole 42 are provided with internal threads matching the pre-tightening bolt 8. The pre-tightening bolt 8 is screwed into the fastening through hole 42 and the fastening hole 611 to fix the convex block 6 and the hinge seat 4, completing the fastening operation after the hinge seat 4 is sleeved on the raised portion 61, thereby achieving a fixed connection between the steel belt joint 2 and the straight-edge rail 1, and realizing the fixed installation of the entire steel belt rail.

[0045] like Figure 1 , 2 As shown, a strip guide slot 22 for accommodating the hinge seat 4 is provided in the middle of the steel strip joint 2 along the circumference of the steel strip joint 2, and the protrusion 61 on the convex block 6 passes through the strip guide slot 22 and matches the strip slot 41 on the hinge seat 4. Through the strip guide slot 22, the convex block 6 can be installed on the inner side of the steel strip joint 2, so that the convex block 6 can serve as a support and a support leg 10 between the steel strip joint 2 and the pipeline. In addition, the protrusion 61 of the convex block 6 passes through the slot, and the hinge seat 4 can be accommodated in the slot without affecting the matching connection with the protrusion 61 on the convex block 6.

[0046] like Figure 2 , 4 As shown, the pad 7 is set as a T-shaped pad 7, and the lower end of the T-shaped pad 7 is slidably connected with the strip guide groove 22. The width of the protruding portion 61 at the lower end of the T-shaped pad 7 is the same as the width of the strip guide groove 22. The lower end of the T-shaped pad 7 is placed in the strip guide groove 22, and the T-shaped pad 7 can slide along the circumferential direction of the steel belt joint 2 in the strip guide groove 22 and play a guiding role at the same time, so as to ensure that there is no deviation in the axial direction of the steel belt track during the pre-tightening installation process, thereby ensuring the accuracy and convenience of the installed steel belt track.

[0047] In addition, a number of legs 10 are arranged at intervals on the inner side of the straight-side track 1 and the steel belt joint 2. The entire steel belt track is supported by the legs 10, so that the steel belt track and the pipe are spaced apart, which facilitates the movement of the trolley arranged on the steel belt track. The two ends of the straight-side track 1 are overlapped at the two ends of the steel belt joint 2. The steel belt joint 2 is arranged on the inner side of the straight-side track 1, and a gasket steel belt 11 is arranged between the steel belt joint 2 and the straight-side track 1. At the same time, a strip hole is opened on the gasket steel belt 11, and the strip hole is convenient for screws 9 to pass through. The specific installation method is that at one end of the steel belt joint 2 and the straight-side track 1 that are fixedly connected by screws 9, the screws 9 pass from the outside to the inside through the straight-side track 1, the strip hole of the gasket steel belt 11 and the steel belt joint. The positioning hole 21 of the head 2 is screwed and fastened with the support leg 10. At the other end of the steel belt joint 2, the screw 9 passes through the strip hole of the gasket steel belt 11 and the positioning hole 21 of the steel belt joint 2 from the outside to the inside and is screwed and fastened with the support leg 10. In the middle position of the steel belt joint 2, the screw 9 passes through the strip hole of the gasket steel belt 11 and the positioning hole 21 on the steel belt joint 2 and is screwed and fastened with the convex block 6. By changing the convex block 6 connected to different positions in the middle of the steel belt joint 2, it can be installed on pipes of different diameters.

[0048] According to the above embodiment, by setting the gasket steel strip 11 between the steel strip joint 2 and the straight edge track 1, the spacing distance between the steel strip joint 2 and the straight edge track 1 is kept constant, and the straight edge track 1 and the steel strip joint 2 are overlapped together, such as Figure 1 , 2 As shown, the trolley with double groove wheels moving on the track is always on the track when passing through the steel belt joint 2, and can smoothly complete the circular motion on the steel belt track. In addition, since the steel belt joint 2 is arranged on the inner side of the straight-edge track 1, the distance between the steel belt joint 2 and the straight-edge track 1 is different from the distance on the surface of the pipeline to be installed, so the height of the support foot 10 arranged on the inner side of the steel belt joint 2 is less than the height of the support foot 10 arranged on the straight-edge track 1, and the height difference is the radial distance between the inner surface of the steel belt joint 2 and the inner surface of the straight-edge track 1, so that the arc track formed by the steel belt joint 2 and the straight-edge track 1 is installed on the pipeline through the support foot 10 in a rounded and fit manner, which facilitates the smooth movement of the trolley.

[0049] During specific installation, first pre-adjust the convex block 6 to a suitable position according to the diameter of the pipe, then wrap the steel belt track around the outer circumference of the pipe to be tested, embed the lower end of the T-type pad 7 into the strip guide groove 22 on the steel belt joint 2, slide it to a suitable position, overlap the strip groove 41 of the hinge seat 4 on the raised portion 61 of the convex block 6, and after matching, tighten the pre-tightening bolt 8. The whole process is convenient and quick to install, saving time and effort. When disassembling, you only need to loosen the pre-tightening bolt 8; if the diameter difference is too large during installation, you can change the length of the connecting mechanism 3 by rotating the threaded pull rod 5 to meet the requirements of different pipe diameters. If the length of the threaded pull rod 5 cannot meet the requirements, by changing the position of the convex block 6 on the steel belt joint 2, changing the circumferential distance between the convex block 6 and the hinge seat 4 to meet the requirements of pipes with different pipe diameters, it not only has a wide range of adaptability but also strong adaptability, and can also adapt well to installation of pipes with poor roundness.
