Description

Technical Field

[0001] The utility model relates to the technical field of cable winding, in particular to a cable winding device for a pavement roughness meter used in supervision. Background Technique

[0002] The pavement roughness meter is applicable to the construction inspection, acceptance inspection of roads such as highways, urban roads, squares, airport runways, etc., and the maintenance of roads. The pavement roughness meter consists of mechanical and electrical parts. The electrical part is separately installed in the instrument box, and there is a cable connected to the interfaces of the displacement sensor and the distance sensor;

[0003] In a pavement roughness meter for supervision with the publication number of CN218233079U, a pavement roughness meter for supervision includes a pavement roughness meter body. The pavement roughness meter body includes a mechanical component, an electrical component is arranged above the mechanical component, a U-shaped plate is sleeved outside the mechanical component, a connecting plate is fixedly installed outside the U-shaped plate, a limiting seat is fixedly installed outside the connecting plate, and an external hole is opened outside the U-shaped plate. In the utility model, by sleeving the U-shaped plate outside the mechanical component and then connecting the screw with the external hole in a threaded manner, the U-shaped plate can be limited to a certain extent. Then, by placing the cable inside the limiting seat, the fixing work of the cable can be completed. At the same time, the arranged sliding beads can change the position of the U-shaped plate, so that the device can operate flexibly, and the device is simple to operate, easy to install and disassemble, and can be continuously used for subsequent work; when the above-mentioned prior art is used, only multiple groups of limiting seats are installed on the pavement roughness meter to limit the cable. However, the cable used by the electrical component on the pavement roughness meter is relatively long, and there is a lack of corresponding winding design during the above actual use. That is, when the cable length is too long, the limiting effect on the cable is limited, and it cannot meet different usage requirements. The too-long cable is not easy to handle, resulting in poor applicability in actual use. And when the cable is limited by the limiting seat, the limiting seat is a ring-shaped structure with an opening on one side, and there is a lack of corresponding clamping component inside, that is, the limiting effect on the cable is not good. When performing pavement roughness detection, affected by the unevenness of the road surface, a certain vibration force will be generated, and then the cable is easy to break away from the limiting seat, which will cause wear to the cable. Therefore, corresponding improvements are needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable winding device for a pavement roughness meter used in supervision, so as to solve the problems in the above background technique that the existing cable winding device for a pavement roughness meter used in supervision lacks a cable winding design, has a single function, lacks clamping and limiting of the cable, and results in poor applicability of the device.

[0005] To achieve the above object, the present utility model provides the following technical solution: A cable winding device for a road surface flatness meter used in supervision, including a supporting seat, an installation rail is arranged on the outer side of the supporting seat, and adjustment holes are uniformly arranged inside the installation rail. Limit seats are uniformly installed on the outer side of the installation rail, a limiting component is arranged between the limit seats, a connecting block is installed on one side of the limit seat, and a disassembly mechanism is arranged on one side of the connecting block. An installation disk is installed on one side of the supporting seat, and a winding component is arranged on one side of the installation disk. The winding component includes a winding shaft installed on the outer side of the installation disk. Arc-shaped blocks are installed on the outer side of the installation disk at both ends of the winding shaft, and elastic blocks are uniformly installed on one side of the arc-shaped blocks. Anti-detachment blocks are installed on one side of the elastic blocks. Fixing mechanisms are uniformly arranged on one side of the supporting seat.

[0006] When using the cable winding device for a road surface flatness meter of this technical solution, during use, by setting the installation disk and the winding shaft, it is convenient to wind the cable during the use of the flatness meter, avoiding the cable being too long and dragging on the ground, causing wear and affecting the use.

[0007] Preferably, the limiting component includes spiral springs installed on both sides inside the limit seat, and restraint semi-rings are installed at one end of each spiral spring for clamping the cable.

[0008] Preferably, the cross-section of the restraint semi-ring is arc-shaped, and anti-wear convex columns are uniformly installed inside the restraint semi-ring.

[0009] Preferably, the elastic block is corrugated and made of natural rubber.

[0010] Preferably, the fixing mechanism includes a clamping frame, and the clamping frame is installed on one side of the supporting seat. A screw rod is threadedly connected inside the clamping frame, and a pushing block is installed at one end of the screw rod. A pressing block is installed on one side inside the clamping frame.

[0011] Preferably, the disassembly mechanism includes a plug-in block, and the plug-in block is installed on one side of the connecting block. A bidirectional screw rod is installed inside the plug-in block, and support plates are threadedly connected to both ends of the outer side of the bidirectional screw rod.

A rotating handle is installed at one end of the bidirectional screw rod, and a positioning disk is sleeved on one end of the outer side of the bidirectional screw rod. The positioning disk is connected to the plug-in block through a fixing pin.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The cable winding device of the pavement evenness tester for supervision is not only convenient for winding the too-long cables, has the effect of preventing the cables from loosening, but also has a good limiting effect on the cables. Moreover, the limiting member can be disassembled and installed at different positions to meet the limiting requirements of different points. In addition, the overall device is convenient for installation and disassembly, and has good use flexibility;

[0013] By providing a winding assembly, when in use, the too-long cables during the use of the pavement evenness tester can be wound to prevent the cables from being worn due to dragging. That is, one end of the cable of the electrical components on the pavement evenness tester is wound back and forth around the winding shaft, that is, it is wound. After the cables are wound and stacked on the winding shaft, they abut against the anti-detachment block and move outward, and the elastic block is stressed and deformed by extrusion.

The operation is convenient to ensure the comprehensiveness of cable positioning. Then, by the mutual cooperation of the spiral spring and the restraining semi-ring, the too-long cables can be clamped and limited to prevent loosening and avoid wear caused by the cables falling;

[0015] By clamping the clamping frame on one side of the pavement evenness tester, and then rotating the screw rod to push the push block to move to one side, that is, making the push block approach the pressing block, the clamping frame can be conveniently installed on the pavement evenness tester to wind the too-long cables, and the operation is convenient.

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A cable winding device for a pavement evenness detector for supervision, comprising a supporting seat 1, a mounting rail 2 is arranged on the outer side of the supporting seat 1, and adjusting holes 201 are uniformly arranged inside the mounting rail 2, limiting seats 5 are uniformly mounted on the outer side of the mounting rail 2, and a limiting assembly is arranged between the limiting seats 5;

[0025] The limiting assembly includes spiral springs 11 mounted on both sides inside the limiting seats 5, and a restraint semi-ring 12 is mounted at one end of each spiral spring 11 for clamping the cable;

[0026] The cross section of the restraint semi-ring 12 is arc-shaped, and anti-wear convex columns 1201 are uniformly mounted inside the restraint semi-ring 12;

[0027] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 5As shown in the figure, during use, pass the cable on the road surface flatness meter for supervision through the limit seat 5, so that the outer wall of the cable abuts against the constraint semi-ring 12. With the elastic deformation performance of the spiral spring 11, the cable can be effectively limited. With multiple groups of anti-wear convex columns 1201, the wear on the cable can be reduced when pulling the cable;

[0028] A connecting block 501 is installed on one side of the limit seat 5, and a disassembly mechanism 7 is arranged on one side of the connecting block 501;

[0029] The disassembly mechanism 7 includes a plug-in block 701, and the plug-in block 701 is installed on one side of the connecting block 501. A bidirectional screw rod 702 is installed inside the plug-in block 701. At both ends of the outer side of the bidirectional screw rod 702, there are threaded connections with support plates 703. Plug-in columns 704 are installed on one side of each support plate 703, and one end of each plug-in column 704 extends into the adjustment hole 201. One end of the bidirectional screw rod 702 is installed with a rotating handle 705. A positioning disk 706 is sleeved on one end of the outer side of the bidirectional screw rod 702, and the positioning disk 706 is connected to the plug-in block 701 through a fixing pin;

[0030] Specifically, as Figure 2 、 Figure 3 shown in the figure, during use, rotate the rotating handle 705 to drive the bidirectional screw rod 702 to rotate. With the threaded connection between the bidirectional screw rod 702 and the support plates 703, the two support plates 703 can be made to approach or move away from each other, so that the plug-in columns 704 can be conveniently inserted into or pulled out of the adjustment hole 201, and the limit seat 5 can be conveniently installed on one side of the support seat 1. Since multiple groups of adjustment holes 201 are provided, the installation position of the limit seat 5 can be adjusted accordingly, and the cable during the use of the road surface flatness meter for supervision can be conveniently limited, preventing the cable from becoming loose and avoiding unnecessary wear on the cable;

[0031] An installation disk 3 is installed on one side of the support seat 1, and a winding component is arranged on one side of the installation disk 3. The winding component includes a winding shaft 4 installed on the outer side of the installation disk 3. Arc-shaped blocks 8 are installed on the outer sides of the installation disk 3 at both ends of the winding shaft 4, and elastic blocks 9 are uniformly installed on one side of each arc-shaped block 8. Anti-detachment blocks 10 are installed on one side of each elastic block 9;

[0032] The elastic block 9 is wavy and is made of natural rubber;

[0033] Specifically, as Figure 1 、 Figure 4 shown in the figure, during use, wind the excess cable around the winding shaft 4, that is, wind up the cable. And during the winding process, as it stacks against the anti-detachment block 10, the elastic block 9 is deformed by the force. When the cable is wound up, the elastic block 9 returns to its original position and pushes the anti-detachment block 10 against the wound cable, preventing the cable from becoming loose;

[0034] One side of the supporting seat 1 is evenly provided with a fixing mechanism 6;

[0035] The fixing mechanism 6 includes a clamping frame 601, and the clamping frame 601 is installed on one side of the supporting seat 1. A screw rod 604 is threadedly connected inside the clamping frame 601, and a push block 603 is installed at one end of the screw rod 604. One side inside the clamping frame 601 is provided with a pressing block 602;

[0036] Specifically, as Figure 1 , Figure 2 shown, during use, the clamping frame 601 is clamped on one side of the road surface roughness meter, and the supporting seat 1 can be conveniently disassembled and assembled by cooperating with the screw rod 604, the push block 603 and the pressing block 602, and the operation is convenient.

[0037] Working principle: When the utility model is in use, first, the supporting seat 1 is leaned against one side of the road surface roughness meter, that is, the clamping frame 601 is clamped on the road surface roughness meter, and then the screw rod 604 is rotated to push the push block 603 against the outside of the road surface roughness meter and cooperate with the pressing block 602, so that the supporting seat 1 can be fixedly installed on the road surface roughness meter. Performing the opposite operation can disassemble it for later cleaning and maintenance;

[0038] Secondly, one end of the too long cable on the electrical components on the road surface roughness meter is passed through the limiting seat 5. That is, under the elastic force of the spiral spring 11, the constraint semi-ring 12 can be pushed against the outer wall of the cable to initially limit the cable. Then the cable is continuously arranged, and one end of it is wound around the winding shaft 4. The number of winding turns is adjusted according to the cable length. During the winding process of the cable, it abuts against the anti-detachment block 10, so that the elastic block 9 is squeezed and deformed. After the winding is completed, the elastic block 9 is reset and pushes the anti-detachment block 10 against the cable to prevent the cable from becoming loose after being wound. Then one end of the cable is passed through the limiting seat 5 at the other end of the supporting seat 1. The operation is convenient and it can prevent the cable from being too long and dragging on the ground causing unnecessary wear;

[0039] Finally, during the cable winding process, the cable can be limited at different positions as needed. That is, the plug-in block 701 is inserted into the installation rail 2, and then the rotary handle 705 is manually rotated to drive the bidirectional screw rod 702 to rotate. By using the threaded connection between the bidirectional screw rod 702 and the supporting plate 703, the plug-in column 704 can be pushed into the adjustment hole 201 to complete the installation of the limiting seat 5. Performing the opposite operation can complete the disassembly of the limiting seat 5 to adjust the position and quantity of the limiting seat 5 according to the use requirements later, improving the flexibility of the device in use.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
