Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement pole quality inspection technology, specifically a tapered cement pole quality inspection device. Background Technology
[0002] In the fields of power, communications, and railways, tapered cement poles (also known as tapered concrete poles) are widely used as supporting structures for overhead lines. They are pole-shaped cement products, tapering at the top and thicker at the bottom, resembling a frustum of a cone. Their quality directly affects the safe and stable operation of the power lines.
[0003] After the production of tapered cement poles is completed, flaw detection is a crucial step in ensuring their quality. Flaw detection can promptly identify potential internal defects such as cracks and voids, preventing safety accidents caused by quality issues. However, in current production practices, traditional flaw detection equipment has significant limitations. Traditional equipment typically requires transferring the finished tapered cement poles to specialized testing platforms for inspection. This transfer process not only necessitates additional handling equipment, such as cranes and forklifts, increasing equipment costs and operational complexity, but also poses a risk of secondary damage due to the large size and weight of the tapered cement poles, such as collisions and tilting, potentially affecting their quality. Furthermore, the transfer operation consumes considerable manpower and time, reducing production efficiency and increasing production costs.
[0004] Therefore, this utility model provides a quality testing device for tapered cement poles. Utility Model Content

[0010] Preferably, a motor is embedded in the inner side of the handle and one end of the support block, one of the motors being connected to the lead screw and the other motor being connected to the winding wheel.
[0011] Beneficial effects
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] This invention utilizes a combination of a support rod, a support block, support legs, and a flaw detector. Workers hold the support rod and extend the support block into the conical cement pole. As the device extends, the flaw detector inspects different areas inside the cement pole. The three support legs, propelled by an elastic telescopic rod, support the support block, allowing it to approach the center of the cement pole. This facilitates even distribution of the three flaw detectors across the inspection area. The device is portable; after production, the cement poles are stacked in the storage area, and workers can use the device to inspect each one thoroughly. This improves the efficiency and quality of flaw detection in conical cement poles, reduces unnecessary transfer operations and potential damage to the cement poles, and meets the needs of actual production.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 A quality inspection device for a conical cement pole includes a support rod 1, a support block 2 installed at one end of the support rod 1, and three flaw detectors 3 installed on the outside of the support block 2.
[0021] Among them, the support block 2 has three support legs 21 hinged to the outside, and the three flaw detectors 3 are all located between two corresponding support legs 21. A wear-resistant sliding plate 211 is installed on one side of each of the three support legs 21, and a rounded corner 212 and a right angle 213 are provided at one end of the support leg 21.
[0022] It should be noted that the support leg 21 described in this embodiment can be tilted and folded towards the support rod 1.
[0023] Each of the three support legs 21 has a roller 22 installed at one end, and the roller 22 protrudes from the outside of the support leg 21.
[0024] It should be noted that the support leg 21 described in this embodiment contacts the tapered cement pole through the roller 22.
[0025] Three elastic telescopic rods 23 are hinged to the outside of the support block 2, and the three elastic telescopic rods 23 are respectively hinged to one side of the corresponding support leg 21.
[0026] It should be noted that the elastic telescopic rod 23 described in this embodiment is equipped with a spring inside, so that the elastic telescopic rod 23 can push the support leg 21.
[0027] Specifically, to address the transportation difficulties and secondary damage caused by the need to move the conical cement pole in traditional testing methods, this testing device uses a support rod 1 to support a support block 2. The support block 2, in turn, supports the support legs 21 and the flaw detectors 3. The three support legs 21 and three flaw detectors 3 are arranged in a circular array on the outside of the support block 2, improving space utilization. Furthermore, the individual operation of the support legs 21 and the flaw detectors 3 does not interfere with each other. The three support legs 21 are rotated perpendicular to the support block 2 by the corresponding elastic telescopic rods 23, with right angles 213 pressing against the outside of the support block 2 to prevent excessive rotation. The rounded corners 212 allow the support legs 21 to rotate within a set angle. During use, the operator holds the support rod 1 to move the support block 2 towards the conical... The device extends into the cement pole, and the three unfolded support legs 21 are first folded accordingly by the limit of the cement pole. The support legs 21 contact the cement pole through the wear-resistant sliding plate 211 to reduce friction damage and frictional resistance. Then, the support legs 21 contact the inner wall of the cement pole through the roller 22 and roll. The three support legs 21 support the support block 2 under the push of the elastic telescopic rod 23, so that the support block 2 can approach the center of the cement pole. The three flaw detectors 3 inspect different areas inside the cement pole as the device extends. This device can be carried by hand. After production, the cement poles are stacked in the storage area, and the staff can use this device to conduct in-depth inspections one by one, which improves the efficiency and quality of flaw detection of tapered cement poles, reduces unnecessary transfer operations and potential damage to cement poles, and meets the needs of actual production.
[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a sleeve 11 is slidably connected to the outside of the support rod 1, a handle 12 is installed at one end of the sleeve 11, and a lead screw that drives the support rod 1 is rotatably connected to the inner wall of the sleeve 11.
[0029] It should be noted that the sleeve 11 and handle 12 described in this embodiment are telescopically adjustable.
[0030] Specifically, the sleeve 11 wraps around the support rod 1. By controlling the rotation of the screw, the length between the support rod 1 and the sleeve 11 can be adjusted. When the sleeve 11 slides away from the support block 2, the support mechanism formed by the support rod 1 and the sleeve 11 can achieve telescopic adjustment, so that the device can be used to test cement poles of different lengths. The handle 12 makes it easy for workers to hold and control the device.
[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the three flaw detectors 3 is equipped with a protective cover 31 on its outer side, and all three protective covers 31 are installed on the outer side of the support block 2.
[0032] It should be noted that the protective cover 31 described in this embodiment is located outside the flaw detector 3 and is longer than the flaw detector 3.
[0033] Specifically, the support block 2 supports the protective cover 31, and the protective cover 31 wraps the flaw detector 3 externally, so that the flaw detector 3 can reduce the occurrence of damage from contact and bumping with external objects.
[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the three support legs 21 is equipped with a traction rope 24 on one side, and a winding wheel for pulling the three traction ropes 24 is installed inside the support block 2.
[0035] It should be noted that the traction rope 24 and the elastic telescopic rod 23 exert forces on the support leg 21 in opposite directions as described in this embodiment.
[0036] Specifically, the traction rope 24 is controlled by the winding wheel inside the support block 2. When the winding wheel rotates, it simultaneously winds up the three traction ropes 24, so that the three traction ropes 24 can simultaneously pull the support leg 21 to fold towards the support rod 1 and the support block 2, thereby reducing the overall space occupied by the support block 2 and facilitating the storage of the device after use.
[0037] In one embodiment of this utility model, such as Figures 1-4 As shown, motors are embedded in the inner side of the handle 12 and one end of the support block 2. One motor is connected to the lead screw, and the other motor is connected to the winding wheel.
[0038] It should be noted that the two motors described in this embodiment drive the lead screw and the winding wheel to rotate, respectively.
[0039] Specifically, one motor drives the lead screw in the sleeve 11 to rotate, thereby driving the support rod 1 to complete the extension and retraction sliding of the support rod 1. The other motor drives the winding wheel to rotate, and the winding wheel drives the three traction ropes 24 to wind and unwind.
[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0041] Working principle: During use, the operator holds the handle 12 and sleeve 11 to insert the support block 2 into the cement pole. The three unfolded support legs 21 are first folded by the cement pole's limit. The support legs 21 contact the cement pole through the wear-resistant sliding plate 211, reducing friction damage and frictional resistance. Subsequently, the support legs 21 contact the inner wall of the cement pole through the roller 22 and roll. At the same time, the flaw detector 3, which has entered the cement pole, performs inspection from inside the cement pole. When the cement pole is long, the electric motor drives the lead screw to rotate, allowing the support rod 1 to continue moving away from the handle 12, increasing the range of motion of the support block 2 and the flaw detector 3. This allows for the inspection of cement poles of different lengths. After the inspection is completed, another motor drives the winding wheel to rotate, which in turn drives the three traction ropes 24 to wind up. The three traction ropes 24 can simultaneously pull the support legs 21 to fold towards the support rod 1 and support block 2, thereby reducing the overall space occupied by the support block 2 and facilitating the storage of the device after use.
