Description

Technical Field

[0001] The invention relates to the field of power tower performance detection equipment, and in particular to a power terminal tower body load-bearing performance detection device and a detection method. Background Art

[0002] The power terminal tower is an important facility in the power sector, which can be used to overhead wires and play a role in protection and support. According to the tower structure of the power terminal tower, it can be divided into five types: wine glass type, cat head type, upper type, dry type and barrel type. Among them, the barrel type tower body is mainly composed of a barrel-shaped trunk installed on the ground and a bracket symmetrically installed on the upper side of the trunk for laying wires. In snowy weather, a large amount of ice and snow is easily hung on the wires and brackets. At this time, the accumulated ice and snow will exert great pressure on the tower body, making it possible for the tower body to overturn. Therefore, the load-bearing performance of the tower body needs to be tested before the terminal tower is completed and put into use.

[0003] When testing the load-bearing performance of the tower body, a test point is usually selected on the bracket, and then a wire rope is hung at the test point of the bracket, and then the wire rope is pulled to apply a test force to the tower body. This test method cannot ensure that the wire rope applies vertical force to the bracket, and it is easy to cause an angle between the force application direction and the vertical direction, resulting in inaccurate test results; in addition, when the wire rope is passed around a higher bracket, it is necessary to use lifting equipment and manual work to complete it. This method of hanging the wire rope is not convenient enough, and there is a safety risk that the wire rope will fall. Summary of the invention

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a load-bearing performance detection device for a power terminal tower body, comprising an upper detection component arranged on the outside of a bracket on the terminal tower and a lower detection component located directly below the upper detection component, the upper detection component comprising an upper detection frame clamped and installed on the outside of the bracket, a vertical rod slidingly inserted into the lower part of the upper detection frame, the lower part of the vertical rod inserted into the lower detection component, a steel wire rope for pulling the upper detection component vertically downward is connected and wound between the upper detection component and the lower detection component, an auxiliary component for facilitating the winding of the steel wire rope is slidingly arranged on the right end of the vertical rod, and the lower detection component is used to pull the upper detection frame vertically downward by winding the steel wire rope.

The clamping plates are in threaded cooperation with the bidirectional threaded rod. Clamping threaded rods are symmetrically and rotatably arranged before and after at the lower part of the upper detection frame. The upper end of the rear clamping threaded rod is hinged with a top plate. The lower part of the front side of the top plate is in notch cooperation with the upper end of the front clamping threaded rod. An arc-shaped panel for pushing the upper detection frame to be horizontal is slidably arranged before and after at the rear side of the middle of the upper detection frame.

[0009] Preferably, a reversing wheel is rotatably arranged on the upper side of the front part of the upper detection frame. The reversing wheel is connected to the anti-jump wheel through gear transmission. The two rotating wheels are connected by a belt and rotate synchronously with the reversing wheel. A rotating gear is coaxially installed at the front part of the right rotating wheel. A connecting wheel is rotatably arranged on the left side of the middle of the auxiliary frame. The connecting wheel is connected to the fixed auxiliary wheel through gear transmission. The connecting wheel is connected to the sliding auxiliary wheel and the tensioning component through a belt.

[0013] Preferably, the present invention also provides a method for detecting the bearing performance of the tower body of a power terminal tower, and the specific steps are as follows:

[0014] S1. Set the upper detection frame outside the tower body support and move it to the detection point, and then clamp the position of the upper detection frame in the center of the support through the clamping assembly, so that the upper detection frame remains horizontal.

[0015] S2. Insert the vertical rod into the corresponding position inside the lower detection frame, so that the upper detection frame and the lower detection frame are arranged vertically up and down. Then move the auxiliary frame to the lower side. After that, pull one end of the steel wire rope out of the electric wire rope reel, bypass the moving pulley on the right side to between the fixed auxiliary wheel and the sliding auxiliary wheel, and move the auxiliary slider to the left to drive the sliding auxiliary wheel to clamp the steel wire rope between the sliding auxiliary wheel and the fixed auxiliary wheel.

[0016] S3. Move the auxiliary frame upward to drive the steel wire rope to the upper detection frame. After that, rotate the sliding auxiliary wheel to drive the steel wire rope to pass through the upper sides of the two rotating wheels and the lower side of the anti-jump wheel in turn. Then one end of the steel wire rope moves to the moving pulley on the left under the action of gravity. After that, manually bypass the lower side of the moving pulley on the left and fix it on the steel wire rope fixator.

[0017] S4. After the steel wire rope is fixed, control the electric slider to drive the auxiliary component to move downward, so as to avoid the auxiliary frame blocking the movement of the upper detection frame. After that, start the electric wire rope reel to wind up and pull the upper detection frame vertically downward through the steel wire rope, so as to apply a detection force to the tower body support. When the length of the steel wire rope decreases, it drives the sliding frame to move upward, so as to compress the dynamometer, and then measure the bearing performance of the tower body.

[0018] The beneficial effects of the present invention are as follows:

[0019] First, the present invention uses the clamping assembly to horizontally clamp the upper detection frame at the detection point position of the support. After that, through the vertical rod simultaneously arranged inside the upper detection frame and the lower detection frame, the upper detection frame and the lower detection frame are arranged vertically up and down, so that the steel wire rope can apply a vertical test force to the support through the upper detection frame, ensuring the accuracy of the detection result.

[0020] Second, the present invention uses the cooperation of the fixed auxiliary wheel and the sliding auxiliary wheel to clamp and lift the steel wire rope to the detection point of the support. After that, rotating the sliding auxiliary wheel can conveniently hang the steel wire rope on the support, making the hanging operation simple and fast.

[0021] Third, the present invention uses gear meshing and belt connection, so that when the steel wire rope is hung, the rotating wheel, the anti-jump wheel, the fixed auxiliary wheel and the sliding auxiliary wheel can rotate synchronously, so as to smoothly hang the steel wire rope.

[0022] IV. The present invention uses a ratchet pawl and a ratchet to limit the movement direction of the steel wire rope being hung, so that the steel wire rope cannot retreat, enabling the steel wire rope to be quickly hung and accelerating the detection speed.

[0023] V. The present invention uses an anti-drop component to automatically clamp the steel wire rope that slips and drops, thereby preventing the steel wire rope from falling; and the clamping component can automatically be stuck in the texture groove of the steel wire rope, thereby increasing the clamping ability of the anti-drop component on the steel wire rope.

[0036] The embodiments of the present invention will be described in detail below. The following described embodiments are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0037] Refer to Figure 1 — Figure 3 , a detection device for the bearing performance of the tower body of a power terminal tower, comprising an upper detection component 1 arranged outside the bracket on the terminal tower and a lower detection component 2 located directly below the upper detection component 1. The upper detection component 1 includes an upper detection frame 11 clamped and installed outside the bracket. A vertical rod 12 is slidably inserted through the lower part of the upper detection frame 11, and the lower part of the vertical rod 12 is inserted into the interior of the lower detection component 2. A steel wire rope 3 that vertically pulls the upper detection component 1 downward is connected and wound between the upper detection component 1 and the lower detection component 2. An auxiliary component 4 for facilitating the winding of the steel wire rope 3 is slidably arranged up and down at the right end of the vertical rod 12. The lower detection component 2 is used to vertically pull down the upper detection frame 11 by winding the steel wire rope 3; a clamping component 15 for horizontally clamping the upper detection frame 11 in the central position of the bracket is arranged at the lower part of the upper detection frame 11; when it is necessary to detect the bearing performance of the tower body, first, the upper detection frame 11 is horizontally centered and fixed on the bracket through the clamping component 15, then the position of the lower detection component 2 is located through the vertical rod 12, and then the position of the lower detection component 2 is locked. Subsequently, the steel wire rope 3 is hung and installed between the upper detection component 1 and the lower detection component 2 through the auxiliary component 4, and finally, the lower detection component 2 winds the steel wire rope 3, thereby applying a detection force to the bracket and detecting the bearing performance of the tower body.

[0038] It should be noted that the vertical rod 12 adopts a telescopic structure. After the detection is completed, the length of the vertical rod 12 can be shortened, making the vertical rod 12 convenient to carry and install. The position of the lower detection component 2 can be locked by fixing it to the tower body with a clamp or locking the lower detection component 2 to the ground.

[0039] Refer to Figure 2 — Figure 5 and Figure 9 As shown in FIGS. - and, the clamping assembly 15 includes a bidirectional threaded rod 151 rotatably arranged at the lower part of the upper detection frame 11. Clamping plates 152 for clamping the left and right sides of the tower body bracket are symmetrically sleeved on the left and right sides of the bidirectional threaded rod 151. The clamping plates 152 are in threaded cooperation with the bidirectional threaded rod 151. Clamping threaded rods 153 are rotatably arranged symmetrically in the front and rear at the lower part of the upper detection frame 11. The upper end of the rear clamping threaded rod 153 is hinged to a top plate 154. The lower side of the front part of the top plate 154 is in notch fit with the upper end of the front clamping threaded rod 153. An arc-shaped plate 155 for pushing the upper detection frame 11 to be horizontal is slidably arranged in the front and rear at the rear side of the middle part of the upper detection frame 11. When it is necessary to fix the upper detection frame 11, first, the upper detection frame 11 is sleeved at the detection point outside the bracket. Then, the arc-shaped plate 155 is moved back and forth until the upper detection frame 11 is in a horizontal state. Subsequently, the bidirectional threaded rod 151 is rotated to drive the clamping plates 152 on the left and right sides to approach each other, thereby clamping the upper detection frame 11 at the central position of the bracket. Then, the clamping threaded rods 153 on the front and rear sides are respectively rotated to drive the top plate 154 to fit and press tightly against the lower side of the bracket in cooperation with the inclination angle of the bracket, thereby clamping the upper detection frame 11 horizontally and centrally at the detection point position of the bracket.

[0040] Refer to Figure 1 — Figure 4 and Figure 10, the auxiliary component 4 includes an electric slider 45 slidably arranged up and down on the right side of the vertical rod 12. An auxiliary frame 41 is arranged on the right side of the electric slider 45. A fixed auxiliary wheel 42 is rotatably arranged on the left side of the middle of the auxiliary frame 41. Auxiliary sliders 43 are slidably arranged left and right before and after on the right side of the middle of the auxiliary frame 41. A sliding auxiliary wheel 44 is rotatably arranged between the two auxiliary sliders 43. When the sliding auxiliary wheel 44 approaches the fixed auxiliary wheel 42, it can clamp and fix the steel wire rope 3. An auxiliary threaded rod 431 is rotatably arranged on the left side of the auxiliary slider 43. The auxiliary threaded rod 431 penetrates inside the auxiliary frame 41 and is in threaded cooperation with it; after the lower detection component 2 and the upper detection component 1 are fixed, one end of the steel wire rope 3 is pulled out between the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44. Then, the auxiliary threaded rod 431 is rotated to drive the auxiliary slider 43 to move to the left. The auxiliary slider 43 drives the sliding auxiliary wheel 44 to clamp the steel wire rope 3 between the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44. After that, the electric slider 45 drives the auxiliary frame 41 to move upward. The auxiliary frame 41 drives one end of the steel wire rope 3 to move upward to the upper detection frame 11 through the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44.

[0041] Refer to Figure 2 — Figure 4 , a reversing wheel 141 is rotatably arranged on the upper side of the front part of the upper detection frame 11. The reversing wheel 141 is connected to the anti-jump wheel 14 through gear transmission. The two rotating wheels 13 are connected by a belt and rotate synchronously with the reversing wheel 141. A rotating gear 131 is coaxially installed on the front part of the right rotating wheel 13. A connecting wheel 411 is rotatably arranged on the left side of the middle of the auxiliary frame 41. The connecting wheel 411 is connected to the fixed auxiliary wheel 42 through gear transmission. The connecting wheel 411 is connected to the sliding auxiliary wheel 44 and the tensioning assembly through a belt. When the auxiliary frame 41 moves to the upper side, the connecting wheel 411 is connected to the rotating gear 131 through gear meshing; when the auxiliary frame 41 moves to the upper detection frame 11, it drives the connecting wheel 411 to be connected to the rotating gear 131 through gear meshing, so that the two rotating wheels 13, the anti-jump wheel 14, the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44 can rotate synchronously. At this time, rotating the sliding auxiliary wheel 44 drives the steel wire rope 3 to move upward and sequentially pass through the upper side of the right rotating wheel 13, the lower side of the anti-jump wheel 14 and the upper side of the left rotating wheel 13.

[0042] Refer to Figure 3 , the tensioning assembly in this embodiment includes a tensioning wheel 46 slidably arranged up and down on the front side of the auxiliary frame 41. A tensioning spring is arranged between the upper side of the tensioning wheel 46 and the auxiliary frame 41.

[0043] Refer to Figure 2 — Figure 4, on the upper part of the auxiliary frame 41, a guide wheel 16 is arranged to slide left and right and rotate itself. On the right side of the guide wheel 16, a guide screw rod 161 is rotatably arranged. The guide screw rod 161 penetrates inside the auxiliary frame 41 and is in threaded cooperation with it; when the steel wire rope 3 moves upward, rotating the guide screw rod 161 drives the guide wheel 16 to move leftward, thereby pushing the steel wire rope 3 to bend, so that the steel wire rope 3 penetrates into the upper detection component 1.

[0044] Refer to Figure 3 , Figure 4 and Figure 6 , a ratchet wheel 421 is coaxially installed at the rear side of the fixed auxiliary wheel 42. A pawl 422 is slidably arranged at the rear part of the auxiliary frame 41. A locking block 423 for locking the position of the pawl 422 is slidably arranged at the position corresponding to the pawl 422 at the rear part of the auxiliary frame 41; on one side of the sliding auxiliary wheel 44, a turntable is arranged. When the steel wire rope 3 is conveyed upward by manually rotating the turntable to drive the sliding auxiliary wheel 44, the sliding auxiliary wheel 44 drives the connecting wheel 411 to rotate through a belt. The connecting wheel 411 drives the fixed auxiliary wheel 42 to rotate through a gear transmission. The fixed auxiliary wheel 42 drives the ratchet wheel 421 to rotate. By limiting the rotation direction of the ratchet wheel 421 by the pawl 422, the fixed auxiliary wheel 42 can only convey the steel wire rope 3 upward, so as to quickly install the steel wire rope 3. After the installation of the steel wire rope 3 is completed, the pawl 422 is pulled out of the teeth of the ratchet wheel 421, and the position of the pawl 422 is locked by the locking block 423, so that the steel wire rope 3 can move freely when detecting the tower body.

[0045] Refer to Figure 4 and Figure 7 , anti-falling parts 17 that slide up and down are symmetrically arranged inside the auxiliary frame 41 in the front and rear directions. An anti-falling spring for pushing the anti-falling parts 17 downward is arranged between the anti-falling parts 17 and the auxiliary frame 41. A clamping part 171 that can be stuck in the surface texture of the steel wire rope 3 is rotatably arranged on one side of the anti-falling part 17 close to the steel wire rope 3; when the steel wire rope 3 shows the phenomenon of slipping and falling, the steel wire rope 3 drives the anti-falling part 17 to move downward through the clamping part 171. While the anti-falling parts 17 move downward, they approach each other, thereby clamping the steel wire rope 3 and making the steel wire rope 3 stop falling. The rotating clamping part 171 can adapt to steel wire ropes 3 with different textures for positioning, making the steel wire rope 3 more difficult to fall.

[0046] Refer to Figure 1 and Figure 8, the lower detection component 2 includes a lower detection frame 21. On the upper right side of the lower detection frame 21, an electric rope winder 22 is provided. On the upper left side of the lower detection frame 21, a wire rope fixator is provided. A sliding frame 23 is slidably arranged up and down in the middle of the lower detection frame 21. Moving pulleys 231 are symmetrically and rotatably arranged on the left and right sides of the sliding frame 23. A dynamometer is arranged between the lower side of the inner top wall of the lower detection frame 21 and the upper side of the sliding frame 23. When installing the wire rope 3, it is pulled out from the electric rope winder 22, first wound around the lower side of the moving pulley 231 on the right side, then driven by the auxiliary component 4, the wire rope 3 is wound around the upper side of the rotating wheel 13, and then the continuously moving wire rope 3 falls under the action of gravity and is wound around the lower side of the moving pulley 231 on the left side. Finally, the end of the wire rope 3 is fixed on the wire rope fixator to complete the installation and layout of the wire rope 3. During detection, the electric rope winder 22 is started to wind up, and the upper detection frame 11 is vertically pulled downward through the wire rope 3, so as to apply a detection force to the tower body support. When the length of the wire rope 3 decreases, it drives the sliding frame 23 to move upward, thereby compressing the dynamometer, and then measuring the bearing performance of the tower body.

[0047] It should be noted that the wire rope fixator adopts a wire rope buckle in the prior art. One end of the wire rope is placed inside the clamping seat of the buckle, and then the wire rope is clamped and fixed by tightening the bolt to push the clamping head and the clamping seat.

[0048] In addition, the present invention also provides a method for detecting the bearing performance of the tower body of a power terminal tower, and the specific steps are as follows:

[0049] S1. The upper detection frame 11 is sleeved at the detection point outside the support. Then, the arc-shaped panel 155 is moved back and forth until the upper detection frame 11 is in a horizontal state. Subsequently, the bidirectional threaded rod 151 is rotated to drive the clamping plates 152 on the left and right sides to approach each other, so as to clamp the upper detection frame 11 at the central position of the support. Then, the clamping threaded rods 153 on the front and rear sides are respectively rotated to drive the top plate 154 to fit and press against the lower side of the support in cooperation with the inclination angle of the support, so as to horizontally and centrally clamp the upper detection frame 11 at the detection point position of the support.

[0050] S2. The vertical rod 12 is inserted into the corresponding position inside the lower detection frame 21, so that the upper detection frame 11 and the lower detection frame 21 are arranged vertically up and down. Then, the auxiliary frame 41 is moved to the lower detection frame 21 through the electric slider 45. Then, one end of the wire rope 3 is pulled out from the electric rope winder 22 and bypassed to the lower side of the moving pulley 231 on the right side to between the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44. The auxiliary threaded rod 431 is rotated to drive the auxiliary slider 43 to move to the left, and the auxiliary slider 43 drives the sliding auxiliary wheel 44 to clamp the wire rope 3 between the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44.

[0051] S3. Drive the auxiliary frame 41 to move upward through the electric slider 45. The auxiliary frame 41 drives one end of the steel wire rope 3 to move upward to the upper detection frame 11 through the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44. At this time, the auxiliary frame 41 drives the connecting wheel 411 to be connected to the rotating gear 131 through gear meshing, so that the two rotating wheels 13, the anti-jump wheel 14, the fixed auxiliary wheel 42 and the sliding auxiliary wheel 44 can rotate synchronously. Then rotate the sliding auxiliary wheel 44 to drive the steel wire rope 3 to move upward, and rotate the guiding threaded rod 161 to drive the guiding wheel 16 to move to the left, thereby pushing the steel wire rope 3 to bend, so that the steel wire rope 3 passes through the upper sides of the two rotating wheels 13 and the lower side of the anti-jump wheel 14 in sequence. Then one end of the steel wire rope 3 moves to the left movable pulley 231 under the action of gravity, and then the steel wire rope 3 is wound around the lower side of the left movable pulley 231 and fixed on the steel wire rope fixator.

[0052] S4. Pull the pawl 422 out of the teeth of the ratchet wheel 421, lock the position of the pawl 422 through the locking block 423, reverse-rotate the auxiliary threaded rod 431 to drive the sliding auxiliary wheel 44 to move to the right, so that the sliding auxiliary wheel 44 and the fixed auxiliary wheel 42 no longer clamp the steel wire rope 3. Subsequently, drive the auxiliary frame 41 to move downward to a suitable position through the electric slider 45, so as to avoid blocking the movement of the upper detection frame 11 by the auxiliary frame 41 during detection. Then start the electric rope winder 22 to wind the steel wire rope 3 to vertically pull the upper detection frame 11 downward, thereby applying a detection force to the tower body support. When the length of the steel wire rope 3 decreases, it drives the sliding frame 23 to move upward, thereby compressing the dynamometer, and then measuring the bearing performance of the tower body.

[0053] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
