DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] like Figures 1 to 10 As shown, a utility pole quality inspection device described in an embodiment of the present invention includes an inspection frame 100, an inspection pressure member and a movable support member; a central fixed block 130 is fixedly connected to the middle of the inspection frame 100 for supporting the utility pole 200 to be inspected; a symmetrically arranged slide groove 140 is opened on the inspection frame 100; the inspection pressure member is arranged in the middle of the inspection frame 100; the movable support member is slidably connected in the slide groove 140 on the inspection frame 100, and two groups are provided, respectively located at the two ends of the inspection frame 100; the movable support member includes a base 300, a jack 310, a column 320, and an upper support unit; the jack 310 is arranged in the middle of the base 300, and the output end of the jack 310 passes through the top of the base 300 and is connected to the bottom of the column 320, the upper support unit is fixed to the top of the column 320, and is also used to support the utility pole 200 to be inspected; the upper support unit is slidably connected in the slide groove 140.

[0039] In the prior art, since the cement poles to be inspected are generally heavy, a lifting device is required to lift the cement poles after production to the inspection equipment for quality inspection. However, during the inspection of cement poles, the inspection is usually limited to one position. When multiple points on the cement pole need to be inspected, the lifting device needs to be repeatedly adjusted, which is relatively cumbersome.

[0040] In view of the above, in one embodiment of the present invention, Figure 1 For example, the electric pole 200 to be inspected is placed centrally on the inspection frame 100 using a lifting device, and during the lifting process, the two ends of the electric pole 200 to be inspected are assisted by staff to pull so that the electric pole 200 to be inspected falls exactly on the middle fixed block 130, and the middle fixed block 130 performs a preliminary limit on the electric pole 200 to be inspected, and then the jack 310 is started to drive the column 320 and the upper support unit to move upward, and the upper support unit performs a secondary limit and fixation on the electric pole 200 to be inspected, and then the inspection pressure piece is used to apply pressure to the electric pole 200 to be inspected until cracks appear on the surface of the electric pole 200 to be inspected, and the pressure value of the electric pole 200 to be inspected at this time is recorded; when it is necessary to inspect other positions on the electric pole 200 to be inspected During the test, the test point is determined, and then the jack 310 is started again to move the column 320 and the upper support unit further upward. When the upper support unit moves further upward and lifts the electric pole 200 to be tested, the electric pole 200 to be tested is separated from the central fixed block 130. At this time, the central fixed block 130 and the test frame 100 are not under pressure. The staff controls the displacement of the test frame 100 and the test pressure piece until the test pressure piece is at the next test point. It is worth noting that before the test frame 100 is displaced, it is necessary to ensure that after the test frame 100 is displaced, both movable supports will not be separated from the test frame 100. If separation may occur, one of the movable supports needs to be adjusted in advance, and the adjustment direction is the moving direction of the test frame 100.

[0041] like Figures 1 to 5 As shown, the upper support unit includes a movable block 340 and a slider 341; two movable blocks 340 and sliders 341 are provided on the column 320 and are arranged symmetrically; the slider 341 is fixed to the top of the column 320, and the movable block 340 is fixed to the top of the slider 341, and the slider 341 is slidably connected in the slide groove 140.

[0042] In combination with the above, when the jack 310 is used to drive the upper support unit to move upward, that is, to drive the slider 341 and the movable block 340 to move upward, it can be understood that in the initial stage, the bottom of the movable block 340 is in contact with the upper surface of the detection frame 100, and the inner inclined surface of the movable block 340 is slightly lower than the inner inclined surface of the middle fixed block 130. When it is necessary to support the electric pole 200 to be detected and to separate the electric pole 200 to be detected from the middle fixed block 130, the jack 310 is used to drive the column 320 and the upper support unit to move upward. When the unit moves upward, the movable block 340 can be driven to move upward through the column 320 and the slider 341. At this time, the inner inclined surface of the movable block 340 is first collinear with the inner inclined surface of the middle fixed block 130, and then higher than the inner inclined surface of the middle fixed block 130, so that the electric pole 200 to be inspected can be lifted and the middle fixed block 130 can be separated from the electric pole 200 to be inspected. In addition, whether it is driving the detection frame 100 to move or driving the movable support to move, it is achieved by the sliding cooperation of the slider 341 and the slide groove 140.

[0043] like Figures 1 to 6 As shown, a clearance groove 324 is provided at the top of the column 320, and a central axis is fixedly connected to the bottom surface of the clearance groove 324, a cone block 323 is sleeved on the central axis, a second spring 325 is sleeved on the central axis, and two ends of the second spring 325 are respectively fixed between the bottom surface of the cone block 323 and the bottom surface of the clearance groove 324; the cone block 323 is located between the two sliders 341.

[0044] During the sliding cooperation between the movable support and the detection frame 100, when the detection frame 100 is moved, since the distance between the two movable support members is not adjusted, it may cause one of the movable support members to separate from the detection frame 100 when the detection frame 100 slides, affecting the detection process. Therefore, in one embodiment of the present invention, a pressure sensor is provided at the bottom of the detection frame 100, and during the sliding process of the detection frame 100, the cone block 323 is squeezed by the second spring 325 and is always pressed against the pressure sensor at the bottom of the detection frame 100, so that the pressure sensor always has a value. When the detection frame 100 When being moved by the staff, if one of the movable supports is detached from the detection frame 100, the cone block 323 will be separated from the detection frame 100, resulting in the loss of the pressure sensor value. At this time, the alarm device matched with the pressure sensor will generate an alarm, thereby reminding the staff that one of the movable supports is about to be separated from the detection frame 100. Based on the above, the cone block 323 is used to press the pressure sensor at the bottom of the detection frame 100 under the elastic potential energy of the second spring 325, which can monitor the sliding connection relationship between the movable support and the detection frame 100, thereby timely alarming when the movable support is about to be separated from the detection frame 100.

[0045] like Figures 1 to 6As shown, the movable support member also includes a crossbeam 330, which is fixed on the side wall of the column 320 and is perpendicular to the column 320; the crossbeam 330 is parallel to the slider 341 and is located at the bottom of the slider 341; the crossbeam 330 is on the lower surface of the detection frame 100; and a reinforcing rib 321 is also fixed between the column 320 and the crossbeam 330.

[0046] During the sliding cooperation between the detection frame 100 and the movable support, the movable support may tilt, and the tilted movable support cannot provide good support effect for the electric pole 200 to be detected, thereby causing a safety hazard. So far, in one embodiment of the present invention, a crossbeam 330 is fixed to the side wall of the column 320. The crossbeam 330 is perpendicular to the connection direction of the column 320, so that when the column 320 or the movable support is tilted, it can be restricted. That is, when the movable support is tilted, the crossbeam 330 will be squeezed on the bottom of the detection frame 100, thereby preventing the movable support from tilting.

[0047] like Figures 1 to 4 As shown, a fixed plate 110 is fixedly connected to one side of the middle part of the detection frame 100, and a deflection plate 120 is rotatably connected to the other side. The deflection plate 120 is set as an L-shaped structure; the detection frame 100 and the deflection plate 120 are rotatably connected via a connecting shaft 121; the detection pressure member is set on the deflection plate 120.

[0048] Since the electric pole 200 to be inspected is generally transported to the inspection frame 100 by a lifting device, the closed inspection pressure piece will affect the placement of the electric pole 200 to be inspected. It is understandable that the lifting device lifts the electric pole 200 to be inspected from the production site, adjusts it to the top of the inspection frame 100, and then slowly lowers it to the inspection frame 100. Therefore, the closed inspection pressure piece is not conducive to lowering the electric pole 200 to be inspected. To solve the above problem, in one embodiment of the present invention, the inspection pressure piece is set on the deflection plate 120. When the electric pole 200 to be inspected is not initially limited, the deflection plate 120 is opened 45°, such as Figure 4 As shown, at this time, the top of the detection frame 100 is open, and the lifting equipment can lift the electric pole 200 to be detected and slowly lower it to the detection frame 100. When the electric pole 200 to be detected has been initially limited, the deflection plate 120 is controlled to rotate 45° in the opposite direction, so that the deflection plate 120 and the fixed plate 110 are overlapped and fixed, and then the fixed plate 110 and the deflection plate 120 are locked with bolts, and then the detection of the electric pole 200 to be detected can be carried out. It is worth noting that when the electric pole 200 to be detected is on the detection frame 100, the deflection plate 120 and the fixed plate 110 can be locked, and then when the detection frame 100 moves and adjusts the detection point of the electric pole 200 to be detected, there is no need to reopen the fixed plate 110 and the deflection plate 120.

[0049] like Figures 1 to 4 As shown, a first hydraulic cylinder 150 is also hinged on the connecting shaft 121, and the output end of the first hydraulic cylinder 150 is hinged to the deflection plate 120; an extension arm 127 is fixed to the side wall of the deflection plate 120, and the output end of the first hydraulic cylinder 150 is hinged to the extension arm 127.

[0050] In combination with the above, when the electric pole 200 to be inspected is not lowered onto the inspection frame 100, the deflection plate 120 needs to be opened to leave space for the lowering of the electric wire to be inspected. In one embodiment of the present invention, a first hydraulic cylinder 150 is hinged on the connecting shaft 121, and the output of the first hydraulic cylinder 150 can drive the deflection plate 120 to open 45 degrees, such as Figure 4 As shown, after the electric pole 200 to be inspected has been initially limited, the first hydraulic cylinder 150 can be retracted to drive the deflection plate 120 to reset, and the fixing plate 110 and the deflection plate 120 can be locked by bolts.

[0051] like Figures 1 to 4 、 Figures 7 to 10 As shown, the detection pressure member includes a second hydraulic cylinder 400, which is fixed to the middle of the deflection plate 120, and the output end of the second hydraulic cylinder 400 passes through the deflection plate 120, and the output end of the second hydraulic cylinder 400 is fixed with a pressure block 410.

[0052] After the electric pole 200 to be inspected has been initially limited, the deflection plate 120 is reset to overlap with the fixed plate 110, and then the fixed plate 110 and the deflection plate 120 are locked with bolts. Then the second hydraulic cylinder 400 is controlled to output, driving the pressure block 410 to move downward and gradually contact the electric pole 200 to be inspected. Then the second hydraulic cylinder 400 is gradually output. When cracks appear on the surface of the electric pole 200 to be inspected, the pressure value at this time is recorded, and then the inspection point is changed and the inspection is continued.

[0053] like Figures 1 to 4 、 Figures 7 to 10 As shown, the bottom of the deflection plate 120 is also fixed with a symmetrically arranged shell 122, and a push rod 123 is slidably connected inside the shell 122. A first spring 126 is sleeved on the push rod 123, and both ends of the first spring 126 are fixed between the top surface of the shell 122 and the bottom of the push rod 123.

[0054] After the deflection plate 120 is reset, the second hydraulic cylinder 400 is started to drive the pressure block 410 to apply pressure to the detection point, which may cause the electric pole 200 to be detected to be broken, and the center of gravity of the broken electric pole 200 to be detected will be offset, which may cause the electric pole 200 to be detected to tilt up and detach from the detection frame 100, and at the same time cause a safety hazard to the surrounding staff. In one embodiment of the present invention, after the deflection plate 120 is reset, the push rod 123 on the deflection plate 120 will press the electric pole 200 to be detected under the elastic potential energy of the first spring 126. It is worth noting that the housing 122 can be set to a distance from the pressure block 410 as needed, and it can be foreseen that the closer the distance between the housing 122, the push rod 123 and the pressure block 410, the more the broken electric pole 200 to be detected can be controlled not to tilt up and detach from the detection frame 100 after it is broken, which plays a certain role in ensuring the safety of the staff.

[0055] like Figures 1 to 4 、 Figures 7 to 10 As shown, a pressure rod 124 is also slidably connected in the sleeve 122, and the top of the pressure rod 124 passes through the deflection plate 120, the bottom of the pressure rod 124 slides with the top of the push rod 123, and the bottom of the pressure rod 124 is connected to the top of the push rod 123 via a pin shaft; a pressure plate 401 is fixedly connected to the side of the output end of the second hydraulic cylinder 400, and the pressure plate 401 is used to squeeze the pressure rod 124.

[0056] During the inspection of the electric pole 200 to be inspected, in order to prevent the electric pole 200 to be inspected from breaking due to pressure, the output of the second hydraulic cylinder 400 is used to drive the pressure plate 401 to squeeze the pressure rod 124, and then the pressure rod 124 is used to squeeze the support rod 123, so that the support rod 123 can be pressed tightly on the electric pole 200 to be inspected. Even if the electric pole 200 to be inspected is broken due to excessive pressure from the pressure block 410, it will not tilt up and detach from the inspection frame 100, posing a safety hazard to surrounding staff.

[0057] like Figures 1 to 4 、 Figures 7 to 10 As shown, a movable groove 125 is formed at the bottom of the pressing rod 124 , and the pin at the top of the supporting rod 123 passes through the movable groove 125 .

[0058] It is worth noting that the movable groove 125 opened at the bottom of the pressure rod 124 is used for the movement of the pin shaft. When the second hydraulic cylinder 400 is not output, the pressure plate 401 will not squeeze the pressure rod 124. Therefore, the push rod 123 is only pressed on the electric pole 200 to be detected under the squeezing action of the first spring 126; and when the pressure rod 124 is output with the second hydraulic cylinder 400, the pin shaft migrates from the bottom of the movable groove 125 to the top of the movable groove 125. By changing the length of the movable groove 125, the timing of the pressure rod 124 squeezing the push rod 123 under the action of the pressure plate 401 can be adaptively adjusted to prevent the push rod 123 from exerting too much pressure on the electric pole 200 to be detected, thereby preventing individual detection points on the electric pole 200 to be detected from being damaged in a certain range, thereby affecting the detection results.

[0059] Working Principle: In the existing technology, since the cement poles to be inspected are generally heavy, a lifting device is required to lift the cement poles after production to the inspection equipment for quality inspection. However, during the inspection of cement poles, the inspection is usually limited to one position. When multiple points of the cement pole need to be inspected, the lifting device needs to be repeatedly adjusted, which is relatively cumbersome.

[0060] In view of the above, in one embodiment of the present invention, Figure 1For example, the electric pole 200 to be tested is placed centrally on the testing frame 100 using a lifting device, and during the lifting process, the staff assists in pulling the two ends of the electric pole 200 to be tested so that the electric pole 200 to be tested falls exactly on the middle fixed block 130, and the middle fixed block 130 performs a preliminary limit on the electric pole 200 to be tested, and then the jack 310 is started to drive the column 320 and the upper support unit to move upward, and the upper support unit performs a secondary limit fixation on the electric pole 200 to be tested, and then the detection pressure piece is used to apply pressure to the electric pole 200 to be tested until cracks appear on the surface of the electric pole 200 to be tested. The pressure value of the electric pole 200 to be tested at this time is recorded; when it is necessary to test other positions on the electric pole 200 to be tested, the test point is determined, and then the jack 310 is started again to move the column 320 and the upper support unit further upward. When the upper support unit moves further upward and lifts the electric pole 200 to be tested, the electric pole 200 to be tested is separated from the middle fixed block 130. At this time, the middle fixed block 130 and the detection frame 100 are not under pressure. The staff controls the displacement of the detection frame 100 and the detection pressure piece until the detection pressure piece is at the next detection point. It is worth noting that the detection frame 100 is displaced. Before, it is necessary to ensure that after the detection frame 100 is displaced, the two movable support members will not separate from the detection frame 100. If separation is likely to occur, one of the movable support members needs to be adjusted in advance, and the adjustment direction is the moving direction of the detection frame 100; when the jack 310 is used to drive the upper support unit to move upward, that is, to drive the slider 341 and the movable block 340 to move upward, it can be understood that in the initial stage, the bottom of the movable block 340 is in contact with the upper surface of the detection frame 100, and the inner inclined surface of the movable block 340 is slightly lower than the inner inclined surface of the middle fixed block 130. When it is necessary to support the electric pole 200 to be detected and make the electric pole to be detected When the utility pole 200 is separated from the central fixed block 130, the jack 310 is used to drive the column 320 and the upper support unit to move upward, and the movable block 340 can be driven to move upward through the column 320 and the slider 341. At this time, the inner inclined surface of the movable block 340 is first collinear with the inner inclined surface of the central fixed block 130, and then higher than the inner inclined surface of the central fixed block 130, so that the utility pole 200 to be inspected can be lifted and the central fixed block 130 can be separated from the utility pole 200 to be inspected. In addition, whether it is driving the detection frame 100 to move or driving the movable support to move, it is achieved by the sliding cooperation of the slider 341 and the slide groove 140.

[0061] During the sliding cooperation between the movable support and the detection frame 100, when the detection frame 100 is moved, since the distance between the two movable support members is not adjusted, it may cause one of the movable support members to separate from the detection frame 100 when the detection frame 100 slides, affecting the detection process. Therefore, in one embodiment of the present invention, a pressure sensor is provided at the bottom of the detection frame 100, and during the sliding process of the detection frame 100, the cone block 323 is squeezed by the second spring 325 and is always pressed against the pressure sensor at the bottom of the detection frame 100, so that the pressure sensor always has a value. When the detection frame 100 When being moved by the staff, if one of the movable supports is detached from the detection frame 100, the cone block 323 will be separated from the detection frame 100, resulting in the loss of the pressure sensor value. At this time, the alarm device matched with the pressure sensor will generate an alarm, thereby reminding the staff that one of the movable supports is about to be separated from the detection frame 100. Based on the above, the cone block 323 is used to press the pressure sensor at the bottom of the detection frame 100 under the elastic potential energy of the second spring 325, which can monitor the sliding connection relationship between the movable support and the detection frame 100, thereby timely alarming when the movable support is about to be separated from the detection frame 100.

[0062] When the electric pole 200 to be inspected has not been initially limited, the deflection plate 120 is opened 45 degrees. Figure 4As shown, at this time, the top of the detection frame 100 is open, and the lifting equipment can lift the electric pole 200 to be detected and slowly lower it to the detection frame 100. When the electric pole 200 to be detected has been initially limited, the deflection plate 120 is controlled to rotate 45 degrees in the opposite direction, so that the deflection plate 120 is overlapped and fixed with the fixed plate 110, and then the fixed plate 110 and the deflection plate 120 are locked with bolts, and then the detection of the electric pole 200 to be detected can be carried out. It is worth noting that when the electric pole 200 to be detected is on the detection frame 100, the deflection plate 120 and the fixed plate 110 can be locked. When the detection frame 100 is moved and the detection point of the electric pole 200 to be detected is adjusted, there is no need to reopen the fixed plate 110 and the deflection plate 120; after the electric pole 200 to be detected has been initially limited, the deflection plate 120 is reset to overlap with the fixed plate 110, and then the fixed plate 110 is locked with bolts. The bolt locks the fixing plate 110 and the deflection plate 120, and then controls the output of the second hydraulic cylinder 400 to drive the pressure block 410 to move downward and gradually contact the electric pole 200 to be detected. Then the second hydraulic cylinder 400 gradually outputs. When a crack appears on the surface of the electric pole 200 to be detected, the pressure value at this time is recorded, and then the detection point is changed and the detection is continued. When the deflection plate 120 is reset, the push rod 123 on the deflection plate 120 will press the electric pole 200 to be detected under the elastic potential energy of the first spring 126. It is worth noting that the housing 122 can be set to a distance from the pressure block 410 as needed, and it can be foreseen that the closer the distance between the housing 122, the push rod 123 and the pressure block 410, after the electric pole 200 to be detected is broken, the more the broken electric pole 200 to be detected can be controlled not to tilt and detach from the detection frame 100, which plays a certain role in protecting the safety of the staff.

[0063] The output of the second hydraulic cylinder 400 is used to drive the pressure plate 401 to squeeze the pressure rod 124, and then the pressure rod 124 is used to squeeze the support rod 123, so that the support rod 123 can be pressed tightly against the electric pole 200 to be inspected. Even if the electric pole 200 to be inspected is broken due to excessive pressure from the pressure block 410, it will not tilt up and detach from the inspection frame 100, posing a safety hazard to surrounding workers.
