Description

Technical Field

[0001] This utility model relates to the field of cement pole production technology, specifically a finished product strength testing device for cement pole production. Background Technology

[0002] Cement poles are mainly composed of steel bars and concrete, hence they are also called reinforced concrete cement poles. They are mainly used as overhead line supports in industries such as power, communications, railways, and petroleum.

[0003] The existing technology has the following shortcomings: During the production process of existing cement poles, when testing cement poles, the testing device cannot conveniently perform strength testing at different locations of the cement poles, which leads to inaccurate test results, which in turn affects the testing efficiency of cement poles and consequently the production efficiency of cement poles.

[0004] Chinese patent discloses a finished product strength testing device for cement pole production (authorization announcement number CN217586630U). This patented technology, through the setting of clamping plates and rotating sleeves, allows the first hydraulic cylinder to drive the two clamping plates to move, thereby enabling the clamping plates to clamp and fix cement poles of different sizes. Through the meshing action between the rotating gear and the gear ring, the servo motor drives the rotating sleeve to rotate, which in turn drives the cement pole to rotate. This allows the testing plate to test different positions on the outer periphery of the cement pole, thus making the test results more accurate and improving the testing efficiency of cement poles, thereby facilitating the testing of cement poles by workers.

[0005] However, it has certain drawbacks: its scheme of driving the pole to rotate to achieve multi-angle detection (that is, using a clamping plate and a rotating sleeve to drive the pole to rotate, so that the detection component covers different positions around the pole) still limits its detection range to a local circumferential side of the pole. Specifically, this type of device can only perform circumferential detection on a fixed length section of the pole during the detection process, and cannot achieve continuous detection coverage along the length of the pole, resulting in the risk of missing areas in the detection results.

[0006] The purpose of this invention is to provide a finished product strength testing device for cement pole production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

An L-shaped plate is installed above the base. A telescopic cylinder is fixedly connected to the front end of the upper surface of the L-shaped plate. A testing element is provided at the telescopic end of the telescopic cylinder.

[0009] The lower end of the L-shaped plate is provided with a displacement mechanism, which includes a C-shaped plate.

[0010] As a further embodiment of this utility model: the detection component includes a sliding sleeve, the sliding sleeve has a cavity 1 inside, and the lower surface of the sliding sleeve has a cavity 2 communicating with the cavity 1. A pressure sensor is fixedly connected to the top of the cavity 1, and a slider is movably connected to the cavity 1 below the pressure sensor. A pressure block is fixedly connected to the lower surface of the slider.

[0011] As a further embodiment of this utility model: the upper surface of the base is fixedly connected to a support between two support plates, the L-shaped plate is located behind the support, the telescopic cylinder is located directly above the support, and the upper surface of the support has an arc-shaped surface extending from left to right, in which multiple rolling balls are embedded and connected.

[0012] As a further improvement of this utility model, the lower end of the support plate is slidably connected to the upper surface of the base in the left-right direction.

[0013] As a further embodiment of this utility model: the lower end of the C-shaped plate is fixed to the rear edge of the upper surface of the base, the fixing rod movably passes through the L-shaped plate, the synchronous belt movably passes through the left and right sides of the C-shaped plate, and the lower end of the L-shaped plate is fixed to the outside of the upper belt body of the synchronous belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention drives the cement pole to rotate, enabling the testing component to undergo multi-point uniform pressure testing along its circumference. This effectively acquires strength data at different angles on the same cross-section, avoiding blind spots caused by manual angle adjustments. Simultaneously, the testing component can automatically translate along the pole's length, combined with periodic rotation testing, to achieve continuous coverage testing of the entire circumference of the pole. This improves testing efficiency and ensures the integrity and accuracy of strength data in each area. The combined effect of these two technologies further enhances the reliability of the test results. Attached Figure Description

A motor 4 is fixedly connected to the left side surface of the left support plate 3. A support cover 5 is rotatably connected and fixedly connected to the left side surface of the right support plate 3 and the output end of the motor 4.

The telescopic end of the second cylinder 7 is provided with a detection element 8, which includes a sliding sleeve 9. The telescopic end of the second cylinder 7 is fixedly connected to the upper surface of the sliding sleeve 9. A cavity 1 is opened inside the sliding sleeve 9, and a cavity 2 connected to the cavity 1 is opened on the lower surface of the sliding sleeve 9. A pressure sensor 10 is fixedly connected to the top of the cavity 1, and a slider 11 is movably connected below the pressure sensor 10 in the cavity 1. A pressure block 12 is fixedly connected to the lower surface of the slider 11. The diameter of the cavity 1 is larger than the diameter of the cavity 2. The diameter of the cavity 1 is the same as the diameter of the slider 11, and the diameter of the cavity 2 is the same as the diameter of the pressure block 12.

[0022] The right-side support cover 5 and the right-side support plate 3 can be rotatably connected by bearings;

[0023] The telescopic cylinder 2 is preferably a pneumatic cylinder, which, after extending, drives two support covers 5 to cover the left and right ends of the cement pole for clamping the cement pole.

[0024] The telescopic cylinder 7 is preferably a hydraulic cylinder, which is used to drive the detection piece 8 to move up and down;

[0025] The testing component 8 is located directly above the clamped concrete pole;

[0026] The pressure sensor 10 is connected to an external control system, and its detection data is displayed on an external display device. In the initial state, the upper surface of the slider 11 is just in contact with the detection end of the pressure sensor 10. When the pressure block 12 squeezes the cement pole, the slider 11 squeezes the pressure sensor 10 upward, thereby performing strength testing on the cement pole.

[0027] Motor 4 is used to drive the cement pole to rotate, so that the detection piece 8 can perform a comprehensive inspection of a certain range of the circumferential side of the cement pole (the cement pole is a cylinder, that is, the side of the cylinder); Motor 4 is equipped with a brake, that is, the motor shaft cannot rotate after the power is cut off; Motor 4 is preferably a servo motor or a stepper motor, which can rotate a fixed angle each time it is started.

[0028] Both telescopic cylinder 2 7 and motor 1 4 are connected to an external control system for automated operation; when telescopic cylinder 2 7 extends, motor 1 4 stops running; after telescopic cylinder 2 7 retracts, motor 1 4 runs for a period of time.

[0029] exist Figure 1 and Figure 3 In the middle: The lower end of the L-shaped plate 6 is provided with a displacement mechanism 13, which includes a C-shaped plate 14. The lower end of the C-shaped plate 14 is fixed to the rear edge of the upper surface of the base 1. The inner left and right surfaces of the C-shaped plate 14 are fixed with two fixing rods 15 from top to bottom. The fixing rods 15 move through the L-shaped plate 6. The left and right surfaces of the C-shaped plate 14 are fixed with fixing blocks 16. The rear surface of the left fixing block 16 is fixed with a motor 17. The front surface of the right fixing block 16 and the output end of the motor 17 are rotatably connected and fixed with synchronous pulleys 18. The two synchronous pulleys 18 are movably sleeved with a synchronous belt 19. The synchronous belt 19 moves through the left and right surfaces of the C-shaped plate 14. The lower end of the L-shaped plate 6 is fixed to the outer side of the upper belt body of the synchronous belt 19.

[0030] Motor 2 17 is connected to an external control system for automated operation; and motor 2 17 is equipped with a brake, meaning that the motor shaft cannot rotate after power is cut off; motor 2 17 is preferably a servo motor or a stepper motor, which can rotate a fixed angle each time it is started.

[0031] The rotation of the synchronous belt 19 can drive the L-shaped plate 6 to move a certain distance to the left or right, so that the detection piece 8 can perform a comprehensive inspection of another certain range of the circumferential surface of the cement pole, thereby inspecting the entire circumferential surface of the cement pole.

[0032] exist Figure 1 In the middle: The upper surface of the base 1 is fixed between the two support plates 3 with a support seat 20. The L-shaped plate 6 is located behind the support seat 20. The telescopic cylinder 7 is located directly above the support seat 20. The upper surface of the support seat 20 has an arc-shaped surface that runs from left to right. Multiple rolling balls 21 are embedded in the arc-shaped surface.

[0033] The support 20 is used to support the cement pole;

[0034] The ball bearing 21 reduces the friction between the cement pole and the support 20, making the cement pole rotate more smoothly.

[0035] The working principle of this utility model is as follows: The cement pole is placed on the ball bearings 21 of the support 20. The telescopic cylinder 2 drives the two side support plates 3 to move towards each other, so that the support cover 5 clamps the two ends of the pole. The telescopic cylinder 7 is activated to drive the detection piece 8 to descend, and the pressure block 12 contacts the surface of the pole. The pressure sensor 10 monitors the pressure value in real time. After the single-point test is completed, the telescopic cylinder 7 retracts, and the motor 4 drives the pole to rotate at a fixed angle. The detection piece 8 is pressed down again for testing. This process is repeated to complete the circumferential local area test. Then, the motor 17 drives the L-shaped plate 6 to move laterally through the synchronous wheel 18 and the synchronous belt 19, so that the detection piece 8 is aligned with the untested area of ​​the pole. The rotation-pressing test process is repeated until the entire circumferential side of the pole is covered. The strength is comprehensively evaluated by the pressure data from multiple positions.
