Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of crawlers, and particularly relates to a crawler with adjustable angle for underwater equipment. Background Technique
[0002] In deep-sea cable-laying equipment, crawler-type walking is mainly used. Based on the fact that the seabed is mainly composed of soft soil, sand and silt, which is softer than the land. Compared with the current crawler walking equipment for cable-laying construction on the seabed, the crawlers are lengthened and the crawler plates are widened to obtain an ideal ground pressure. However, even with lengthening and widening, it is impossible to adapt to different soft soils. The ground pressure of the equipment on the seabed between the soil and the silt will vary greatly, and it is impossible to achieve universality.
[0003] When the existing equipment is in use, there will be a phenomenon of slipping. The driving performance of the whole machine on different seabeds is poor. In the face of bad seabed conditions, the whole machine will sink into the soil and cannot be used. It is impossible to adjust the climbing angle and the grip of the crawler, which affects the use effect of the equipment, reduces the work quality, and when in use, it is necessary to change the weight of the whole machine on the seabed to obtain the corresponding ground pressure. However, the buoyancy material is expensive. In order to adapt to the model, the buoyancy material will be processed into special-shaped materials, and the processing cost is high. Moreover, when adapting to different seabeds, increasing or decreasing the buoyancy material will be operated on the mother ship. Multiple engineers climb to the top of the whole machine to disassemble and install the buoyancy material, and then drop the equipment into the seabed. The process is very cumbersome, laborious and time-consuming, and delays the construction period and is not safe. Summary of the Utility Model
[0004] In order to solve the problems raised in the above background technique. The utility model provides a crawler with adjustable angle for underwater equipment, which has the characteristics of preventing slipping and strong applicability.
[0005] To achieve the above object, the utility model provides the following technical scheme: A crawler with adjustable angle for underwater equipment, including a crawler box body. One end of the crawler box body is provided with a tensioner box body. One side of the tensioner box body is provided with a tensioner assembly. The bottom end of the tensioner assembly is provided with an angle adjustment oil cylinder. One side of the bottom end of the angle adjustment oil cylinder is provided with a horizontal telescopic oil cylinder. The output end of the horizontal telescopic oil cylinder is provided with a horizontal telescopic slider group. The bottom end of the crawler box body is provided with a number of idler wheels. One end of the idler wheel away from the tensioner box body is provided with a drive wheel. The surface of the drive wheel is provided with a chain. The surface of the chain is provided with crawler plates. The upper end of the crawler box body is provided with a vertical oil cylinder. The upper end of the vertical oil cylinder is provided with a vertical slider group. The upper end of the vertical slider group is provided with a guide wheel.
[0006] Preferably, the crawler box body is provided with a pin hole corresponding to the tensioner box body. The tensioner box body is installed inside the pin hole through a pin. The angle adjustment oil cylinder and the tensioner assembly are connected by a pin shaft.
[0007] Preferably, the idler is installed at the bottom end of the crawler box body through connecting bolts.
[0008] Preferably, a hydraulic motor is arranged inside the crawler box body, and a hydraulic motor reducer is arranged on one side of the hydraulic motor corresponding to the drive wheel.
[0009] Preferably, a U-shaped groove is arranged inside the crawler box body corresponding to the horizontal telescopic slider group, and a cylinder ear plate is arranged at the upper end of the horizontal telescopic slider group corresponding to the horizontal telescopic cylinder.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] By adjusting the ground area of the crawler, the present utility model obtains different low pressures, thereby changing the ground pressure of the whole machine, preventing the whole machine from sinking into the seabed, improving the anti-slip ability and obstacle-crossing ability of the whole machine. Even if the whole machine has slipped and is trapped in the seabed, this mechanism can be adjusted to get rid of this phenomenon, effectively solving the slipping phenomenon caused by the problem of the ground pressure of the whole machine caused by fewer crawlers, improving the driving performance of the whole machine on different seabeds. Even when facing bad seabed conditions that cause the whole machine to sink into the mud and cannot move, adjusting the climbing angle and grip of the crawler will be more effective to make the whole machine get out of trouble, improving the applicability of the equipment, ensuring the stability of work, having low equipment use cost, simple operation, and being convenient for popularization.

[0022] Specifically, a pin hole is provided at one end of the track box body 7 corresponding to the tensioner box body 2, and the tensioner box body 2 is installed inside the pin hole through a pin, and the angle adjustment oil cylinder 12 and the tensioner assembly 1 are connected by a pin shaft.
[0023] By adopting the above technical solutions, it is ensured that the angle adjustment oil cylinder 12 can push the tensioner assembly 1 to rotate during use, and then drive the tensioner box body 2 to rotate, so as to adjust the ground contact area of the track and the track climbing angle, improve the convenience and stability of equipment adjustment, and ensure the working quality.
[0024] Specifically, the idler wheel 9 is installed at the bottom end of the track box body 7 through a connecting bolt.
[0025] By adopting the above technical solutions, the installation stability of the idler wheel 9 is improved, the running smoothness of the chain 5 is ensured, the walking quality of the track is improved, and the use quality of the equipment is ensured.
[0026] Specifically, a hydraulic motor is arranged inside the track box body 7, and a hydraulic motor reducer is arranged on one side of the hydraulic motor corresponding to the drive wheel 8.
[0027] By adopting the above technical solutions, it is convenient to drive the track, improve the working stability, reduce the driving cost of the equipment, and ensure the quality of the driving work.
[0028] Specifically, a U-shaped groove is arranged inside the track box body 7 corresponding to the horizontal telescopic slider group 11, and an oil cylinder ear plate is arranged at the upper end of the horizontal telescopic slider group 11 corresponding to the horizontal telescopic oil cylinder 10.
[0029] By adopting the above technical solutions, the installation stability and firmness of the horizontal telescopic oil cylinder 10 are improved. When adjusting the ground contact area of the crawler, the horizontal telescopic oil cylinder 10 can drive the horizontal telescopic slider group 11 to move. At the same time, the horizontal telescopic slider group 11 moves inside the U-shaped groove to adjust the position of the idler wheel 9 at its lower end, so as to adjust the length of the crawler plate 4, and adjust the ground contact area of the crawler and the crawler climbing angle, thereby improving the stability of the crawler drive.

[0032] The working principle and usage process of the present utility model: When the present utility model is in use, when it is necessary to adjust the ground area of the equipment, driving the angle adjustment oil cylinder 12 to expand and contract can make the tensioner assembly 1 and the tensioner box body 2 rotate around the hinge point hole at the head end of the crawler box body 7 together, so that the crawler climbing angle increases or decreases accordingly. The change in the climbing angle can improve the passing ability of the whole machine when encountering obstacles, ensure the walking quality of the equipment, and the rotation of the tensioner assembly 1 and the tensioner box body 2 will cause the length of the chain 5 at the tensioner guide wheel and the guide wheel 3 to change. At this time, adjusting the vertical oil cylinder 13 to make the guide wheel 3 and the vertical slider group 6 expand and contract in the up and down direction can make the variable of the length be more effectively converted into the variable of the ground area of the crawler. The expansion and contraction of the horizontal telescopic oil cylinder 10 drives the vertical slider group 6 to slide back and forth in the U-shaped groove inside the crawler box body 7. The sliding in this process directly converts the variable of the elongation of the chain 5 caused by the change in the rotation angle into the variable of the ground area of the crawler, thereby changing the ground pressure of the whole machine and preventing the whole machine from sinking into the seabed, thereby improving the anti-slip ability and obstacle-crossing ability of the whole machine. Even if the whole machine has slipped and been trapped in the seabed, this mechanism can be adjusted to get rid of this phenomenon.
