Description

Technical Field

[0001] The utility model relates to the technical field of cable protection pipe detection, in particular to a device for detecting the compressive strength of a cable protection pipe. Background Technique

[0002] Cables are commonly used in power construction projects. Most cables are laid underground. When laying cables, cable protection pipes need to be sleeved outside the cables, which can avoid cable erosion or interference, and also avoid electric leakage caused by cable damage, greatly improving the service life and safety of the cables. Therefore, it is necessary to detect the compressive strength of the cable protection pipes.

[0003] The existing detection devices are usually vertical. The pressing mechanism applies pressure from above and limits it from both sides. However, the pressing mechanism is in the upper position and is hindered by the upper part, which is not convenient for the staff to directly place. It needs to be pushed from one side and then positioned, which affects the operation. Moreover, the positioning adaptability for cable protection pipes of different sizes is also poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting the compressive strength of a cable protection pipe to solve the problems in the above background technique in view of the defects of the prior art.

[0005] A device for detecting the compressive strength of a cable protection pipe includes a workbench, a detection mechanism and a positioning mechanism installed on the workbench. The positioning mechanism includes a limiting part, a connecting plate, bolts, nuts, a positioning plate, a cylinder, limiting columns and a connecting rod. The two groups of limiting parts are oppositely installed on the workbench and are connected by the connecting plate. The two bolts penetrate through the connecting plate and the degree of freedom of the bolts moving in one direction is restricted by the nuts. The positioning plate is fixed at the end of the bolts. There are two limiting columns, which respectively penetrate through two rectangular grooves on the workbench and are rotatably installed at the bottom of the workbench, and the two limiting columns are fixedly connected by the connecting rod. The cylinder is hinged at the bottom of the workbench, and its output end is hinged to the connecting rod.

[0006] By adopting the above technical solution, it is convenient to place and position the cable protection pipe.

[0007] The detection mechanism includes a hydraulic cylinder, a pressure sensor and a pressing plate. The pressure sensor is installed at the output end of the hydraulic cylinder, and the pressing plate is fixed on the pressure sensor.

[0008] By adopting the above technical solution, pressure detection is carried out on the cable protection pipe.

[0009] One side bottom end of the limiting part is arranged in an inclined arc structure.

[0010] By adopting the above technical solution, cable protection pipes of different sizes can be adapted, placed at the arc-shaped grooves of the limiting parts, and limited and positioned.

[0011] The two rectangular grooves are opened between the two limiting parts, and the distance between them is greater than the widths of the pressing plate and the positioning plate.

[0012] By adopting the above technical solution, it is convenient to toggle the cable protection pipe, push the cable protection pipe to the limiting part, and limit the cable protection pipe.

[0013] The diameter of the limiting post is adaptively set to the width of the rectangular groove.

[0014] By adopting the above technical solution, the limiting post is stable in the rectangular groove.

[0015] The beneficial effects of the compression strength detection device for the cable protection pipe of the present utility model are as follows:

[0016] The cable protection pipe to be detected can be placed on the workbench, below the limiting part. Then, the air cylinder can be driven to pull the connecting rod, driving the limiting post to adjust the angle, so as to limit the cable protection pipe below the limiting part through the limiting post. After the cable protection pipe is restricted, adjust the position of the positioning plate to make the positioning plate fit on one side of the cable protection pipe, and rotate the nut to make the nut fit with the connecting plate, thereby restricting the movement of the positioning plate, facilitating the placement of the cable protection pipe and achieving positioning.

[0020] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0021] Refer to Figure 1-2, A compressive strength detection device for a cable protection pipe, comprising a workbench 1, a detection mechanism and a positioning mechanism installed on the workbench 1. The positioning mechanism includes a limiting part 5, a connecting plate 6, bolts 7, nuts 8, a positioning plate 9, a cylinder 10, limiting columns 11 and a connecting rod 12. The limiting part 5 is installed on the workbench 1 in two groups opposite to each other and is connected by the connecting plate 6. There are two bolts 7 passing through the connecting plate 6, and the freedom of the bolts 7 to move in one direction is restricted by the nuts 8. The positioning plate 9 is fixed to the ends of the bolts 7. There are two limiting columns 11, which respectively pass through two rectangular grooves 101 on the workbench 1 and are rotatably installed at the bottom of the workbench 1, and the two limiting columns 11 are fixedly connected by the connecting rod 12. The cylinder 10 is hinged to the bottom of the workbench 1, and its output end is hinged to the connecting rod 12; the hydraulic cylinder 2, the pressing plate 4 and the positioning plate 9 are arranged in the middle of the workbench 1. When the cable protection pipe is placed on the workbench 1, it needs to be placed above the 101. Subsequently, the cylinder 10 is driven to push the connecting rod 12 to rotate the limiting column 11, so that the limiting column 11 can push the cable protection pipe to the lower part of the limiting part 5. The cooperation between the limiting column 11 and the limiting part 5 can position the cable protection pipe. This device is different from the existing detection devices.

[0022] One side bottom end of the limiting part 5 is arranged in an inclined arc structure; when detecting different cable protection pipes, the limiting column 11 can push them to the arc groove of the limiting part 5, and through the cooperation between the limiting column 11 and the limiting part 5, the cable protection pipe can be restricted.

[0023] The two rectangular grooves 101 are opened between the two limiting parts 5, and the distance between them is greater than the widths of the pressing plate 4 and the positioning plate 9; separating the two limiting columns 11 can avoid affecting the normal pushing of the pressing plate 4 by the hydraulic cylinder 2 to move, and the limiting columns 11 can apply thrust to both ends of the cable protection pipe at the same time, pushing the cable protection pipe to the arc structure of the limiting part 5 to achieve positioning.

[0024] The diameter of the limiting column 11 is set to be adapted to the width of the rectangular groove 101, so that the limiting column 11 has a stable swinging state in the rectangular groove.

[0025] Working principle: The cable protection pipe to be detected can be placed on the workbench 1 so that it is under the limiting part 5. Then, the cylinder 10 can be driven to pull the connecting rod 12, driving the limiting column 11 to adjust the angle, so that the cable protection pipe is restricted under the limiting part 5 by the limiting column 11;

[0026] After the cable protection pipe is restricted, adjust the position of the positioning plate 9 so that the positioning plate 9 fits on one side of the cable protection pipe, and rotate the nut 8 so that the nut 8 fits with the connecting plate 6, thereby restricting the movement of the positioning plate 9;

[0027] The testing mechanism includes a hydraulic cylinder 2, a pressure sensor 3 and a pressing plate 4. The pressure sensor 3 is installed at the output end of the hydraulic cylinder 2, and the pressing plate 4 is fixed on the pressure sensor 3. Then, the hydraulic cylinder 2 can be driven to push the pressing plate 4 to apply pressure to the cable protection pipe, and the data transmitted by the pressure sensor 3 is recorded to realize the compressive test of the cable protection pipe.

[0028] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
