Description

Technical Field

[0001] The utility model relates to the technical field of power equipment installation, in particular to an auxiliary tool for insulation installation of power equipment. Background Art

[0002] Power equipment refers to various equipment and devices used in the transmission, distribution, conversion, regulation, control, protection, and measurement of electric energy.

[0003] The transformer is a type of electrical equipment. When installing the transformer outdoors, a crane is used to lift the transformer. Workers stand on the bridge between two electric poles and place the transformer on the bridge with the help of the crane, and then fix it with bolts.

[0004] However, the prior art has the following defects:

[0005] The transformer is moved by manually controlling the rope on the crane and then fixed on the bridge. Since the rope swings in the air, even if the transformer is placed on the bridge with the cooperation of the workers on the bridge, the position may not be necessarily centered. Later, workers will need to drag the bulky transformer to move it, which is time-consuming and labor-intensive. Summary of the Invention

[0006] In order to solve the technical problem that the transformer is easily misaligned when placed on the bridge and it is laborious for workers to adjust it later, the utility model provides an auxiliary tool for insulating and installing power equipment.

[0007] The utility model adopts the following technical solution to achieve: an auxiliary tool for insulation installation of power equipment.

[0008] It includes a fixing seat and a bridge, wherein two hydraulic cylinders are fixed on the fixing seat, and mounting seats are fixed on the two hydraulic cylinders, and the bridge is located above the mounting seats;

[0009] A clamping mechanism is provided in the mounting seat, and includes a connecting seat and a clamping unit, wherein one end of each of the two connecting seats slides in the mounting seat, and the other end of the connecting seat extends from the connecting seat and is fixed to the clamping unit;

[0010] The lifting mechanism includes a mounting plate, a long rod, a top plate and a cylinder. The mounting plate is fixed in the mounting seat, one end of the two long rods is fixed to the top plate, and the other end of the top plate passes through the mounting plate and is located in the mounting seat. The cylinder is fixed on the mounting plate, and the output end of the cylinder is connected to the top plate to push the top plate to move vertically.

[0011] Through the above technical solution, wheels are provided at the bottom of the fixing seat to push the fixing seat to move, thereby enhancing the overall flexibility of the workpiece.

[0012] The workpiece can be adapted to bridges of different sizes under the action of a clamping mechanism.

[0013] The transformer that has been moved to a good position can be lifted up by the lifting mechanism, and the clamping mechanism is driven not to clamp the bridge, thereby ensuring that the entire workpiece can be kept away from the bridge.

[0014] As a further improvement of the above scheme, the card unit includes an outer L-plate, a card slot, a card block and an inner L-plate, the inner L-plate is fixed on the connecting seat, multiple card blocks are fixed on the inner L-plate, multiple card slots are opened in the outer L-plate, the card blocks are in contact with the card slots, and the outer L-plate can be in contact with the bridge.

[0015] The above technical solution can be applied to bridges of different sizes by sliding the outer L-plate and the inner L-plate. The card blocks can be placed in different card slots, thus ensuring the stability of the installation between the outer L-plate and the inner L-plate.

[0016] As a further improvement of the above solution, a plurality of balls are provided for rolling on a side of the outer L-plate close to the bridge, and the plurality of balls can all contact the bridge.

[0017] According to the above technical solution, a plurality of balls are provided so that the transformer can be placed on the outer L-plate. When the transformer moves on the bridge, the contact between the balls and the bridge can reduce friction, making the transformer move more smoothly.

[0018] When adjusting the position of the transformer, just push the workpiece to move as a whole.

[0019] As a further improvement of the above scheme, the clamping unit also includes a moving unit, which includes a long rack, a pinion and a rotating rod. One end of the rotating rod is fixed in the mounting seat through a bearing, and the pinion is fixed on the rotating rod. The two long racks are fixed on the connecting seat, and the two long racks are engaged with the pinion.

[0020] Through the above technical solution, the two long racks and the pinion are engaged, which can drive the two connecting seats to move together, and then drive the clamping mechanism to complete the clamping work of the bridge, which is convenient for subsequent use.

[0021] As a further improvement of the above scheme, it also includes a large gear, a short rack and a movable groove. The large gear is connected to the rotating rod through a ratchet structure. The two movable grooves are opened through the mounting seat. The short rack is fixed on the long rod on the left, and the short rack can engage with the large gear.

[0022] Through the above technical solution, by setting a ratchet structure between the rotating rod and the large gear, the rotating rod can be driven to rotate only when the short rack moves upward, so that the clamping mechanism is separated away from the bridge, making it easier to remove the device.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The utility model can limit the position of the bridge surface under the action of the clamping mechanism, and when the transformer is placed on the clamping mechanism, it can be moved conveniently and smoothly. At the same time, under the action of the lifting mechanism, when the position of the transformer is adjusted, the clamping mechanism can be removed from the bridge, and then the transformer and the bridge can be fixed and installed using bolts, which can save some labor.

[0032] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0033] An auxiliary tool for insulating and installing power equipment, comprising a fixing base 1 and a bridge 4, wherein two hydraulic cylinders 2 are fixed on the fixing base 1, and a mounting base 3 is fixed on the two hydraulic cylinders 2, and the bridge 4 is located above the mounting base 3;

[0034] The clamping mechanism is arranged in the mounting seat 3. The clamping mechanism includes a connecting seat 10 and a clamping unit. One end of each of the two connecting seats 10 slides in the mounting seat 3, and the other end of the connecting seat 10 extends from the connecting seat 10 and is fixed to the clamping unit;

[0035] The lifting mechanism includes a mounting plate 12, a long rod 13, a top plate 14 and a cylinder 15. The mounting plate 12 is fixed in the mounting seat 3. One end of the two long rods 13 is fixed to the top plate 14, and the other end of the top plate 14 passes through the mounting plate 12 and is located in the mounting seat 3. The cylinder 15 is fixed on the mounting plate 12, and the output end of the cylinder 15 is connected to the top plate 14 to push the top plate 14 to move vertically.

[0036] For details, please refer to Figure 1 、 Figure 2 and Figure 3 First, push the fixing seat 1 to the bottom of the bridge 4, and at the same time start the two hydraulic cylinders 2 to drive the mounting seat 3 and the clamping mechanism to move closer to the bridge 4. The workers pull the clamping mechanisms away from each other, and cooperate with the rise of the mounting seat 3 to move the clamping unit upward from both ends of the bridge 4 until the end of the clamping unit and the end of the bridge 4 are in the same straight line. Then stop driving the hydraulic cylinder 2 to determine the height of the clamping mechanism, and then send the clamping mechanism open to drive the clamping unit and bridge 4 to contact and limit the bridge 4.

[0037] Then place the transformer on the clamping unit and push it horizontally at will to place the transformer in the center.

[0038] After the transformer is centered on the bridge 4, the cylinder 15 is started to drive the top plate 14 and the long rod 13 to move upward, pass through the bridge 4 and contact the transformer, and lift the transformer. The lifting mechanism drives the clamping units to move away from each other.

[0039] It should be noted that the distance moved by the hydraulic cylinder 2 is used in conjunction with the sensor on the clamping unit. This technology is a mature existing technology and will not be described in detail here.

[0040] Furthermore, the card unit includes an outer L-plate 5, a card slot 7, a card block 8 and an inner L-plate 9. The inner L-plate 9 is fixed on the connecting seat 10. Multiple card blocks 8 are fixed on the inner L-plate 9. Multiple card slots 7 are opened in the outer L-plate 5. The card block 8 is in contact with the card slot 7, and the outer L-plate 5 can be in contact with the bridge 4.

[0041] A plurality of balls 6 are provided on a surface of the outer L-plate 5 close to the bridge 4 for rolling, and all of the balls 6 can contact the bridge 4 .

[0042] An insulating pad is provided on the surface of the outer L-plate 5 to ensure the safety of workers.

[0043] For details, please refer to Figure 2 、 Figure 3 and Figure 5 , pull the two connecting seats 10 away from each other so that the bridge 4 is located between the two, and push the two connecting seats 10 closer so that the bottom end face of the bridge 4 can contact the top wide end face of the inner L-plate 9, and then by pressing the outer L-plate 5 downward, the outer L-plate 5 can gradually cover the inner L-plate 9, and the slot 7 can contact the block 8 below until the ball 6 contacts the bridge 4.

[0044] It should be noted that the hydraulic cylinder 2 drives the mounting base 3 to move upward. When the wide end surface at the top of the inner L-plate 9 and the bridge 4 are in the same plane, the hydraulic cylinder 2 stops moving. This activity is used in conjunction with the hydraulic cylinder 2 through the distance sensor provided on the inner L-plate 9.

[0045] Furthermore, the clamping unit also includes a moving unit, which includes a long rack 16, a pinion 18 and a rotating rod 19. One end of the rotating rod 19 is fixed in the mounting seat 3 through a bearing, and the pinion 18 is fixed on the rotating rod 19. The two long racks 16 are both fixed on the connecting seat 10, and the two long racks 16 are both engaged with the pinion 18.

[0046] For details, please refer to Figure 3 and Figure 4 When the two connecting seats 10 are close to or away from each other, the two long racks 16 are driven to move away from or close to each other, driving the pinion 18 to drive the rotating rod 19 to rotate, and the positions of the two connecting seats 10 can be reasonably adjusted according to the different widths of the bridge 4.

[0047] Furthermore, it also includes a large gear 20, a short rack 21 and a movable slot 22. The large gear 20 is connected to the rotating rod 19 through a ratchet structure. Two movable slots 22 are opened through the mounting seat 3. The short rack 21 is fixed on the long rod 13 on the left, and the short rack 21 can engage with the large gear 20.

[0048] For details, please refer to Figure 2 When the rotating rod 19 is driven by the small gear 18 to rotate clockwise, the large gear 20 does not rotate, that is, the large gear 20 does not rotate when the two connecting seats 10 move away from each other. When the rotating rod 19 rotates counterclockwise, it can drive the large gear 20 to rotate, that is, the two connecting seats 10 move closer to each other for clamping. When the cylinder 15 is started and drives the two long rods 13 to move upward and pass through the movable groove 22, the short rack 21 will engage with the large gear 20, driving the large gear 20 to rotate clockwise. The large gear 20 also drives the rotating rod 19 to rotate clockwise, that is, the two long racks 16 separate from each other, causing the connecting seat 10 to drive the outer L-plate 5 and the inner L-plate 9 to move away from each other. The cylinder 15 lifts the transformer. When the outer L-plate 5 is completely away from the bridge 4, the cylinder 15 is retracted, and the short rack 21 drives the large gear 20 to rotate counterclockwise, so that the rotating rod 19 cannot rotate, that is, the two connecting seats 10 maintain a stable position.

[0049] It should be noted that the ratchet structure between the rotating rod 19 and the large gear 20 is a prior art and will not be described in detail here.

[0050] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
