Description

Technical Field

[0001] The present invention belongs to the technical field related to power equipment installation, and specifically relates to a lifting device for installing power equipment used in power engineering. Background Art

[0002] Power equipment refers to various equipment used to produce, transmit, distribute and use electrical energy. Different power equipment has different functions and uses. Power generation equipment includes generators, wind turbines, solar panels, etc. These devices can convert mechanical energy or other forms of energy into electrical energy. Transmission equipment transmits electrical energy from power plants to users through the use of high-voltage transmission lines, substations, transformers and other transfer equipment.

[0003] Power equipment is often installed and used in outdoor environments. To avoid damage to the power equipment, the power equipment is installed at a certain distance from the ground, which can effectively prevent damage to the power equipment and animals from building nests next to the power equipment. Since the power equipment is installed at a high position, a liftable transport vehicle is required to lift the power equipment to a higher position. Since it is inconvenient to measure the alignment position of the power equipment and the higher mounting frame, when the transport vehicle lifts the power equipment to a higher position, there is a gap between the power equipment and the mounting frame. The position of the power equipment is adjusted by constantly moving the transport vehicle, and the universal wheel has a large movement range, which makes it difficult to align the power equipment with the mounting frame, making it inconvenient for staff to install the power equipment.

[0004] To this end, we propose a lifting device for installing power equipment for power engineering. Summary of the invention

[0005] The object of the present invention is to provide a lifting device for installing electric power equipment for electric power engineering to solve the problems raised in the above-mentioned background technology.

The limiting mechanism includes a second bidirectional screw rotatably connected to the inner wall of the lifting plate and two clamping plates for clamping and fixing the electric equipment on the lifting plate; A counterweight mechanism is arranged on the upper surface of the base to improve the movement stability of the base. The counterweight mechanism includes a counterweight box fixedly connected to the upper surface of the base and a plurality of counterweight blocks used to increase the weight of the counterweight box.

[0008] A further technical solution is that when there is a small spacing error between the mounting components of the power equipment and the mounting frame, the position of the power equipment above the lifting plate can be fine-tuned by using a one-way screw and a worm gear to push the mobile platform to move laterally and vertically, thereby making it easier for staff to install the power equipment on the mounting frame.

[0009] Preferably, an insert block is fixedly connected to the end of the rocker, and slots are provided at the ends of the one-way screw and the worm, and the size of the slots matches the size of the insert block.

[0010] A further technical solution is to use an insert block inserted into a slot, so that the rocker can be quickly connected to the one-way screw and the worm, so that a rocker can be shared. The insert block and the slot are a cross structure, have strong hardness, and are more durable.

[0011] Preferably, two guide rods are fixedly connected to the surface of the sliding block, and the two guide rods are slidably connected to the base.

[0012] A further technical solution is that when the mobile platform moves forward, the center of gravity of the mobile platform changes, causing the mobile platform to have a slight tilting force. By using a guide rod for support, the tilt of the mobile platform is prevented from causing damage to the rotating assembly between the one-way screw and the slider.

[0013] Preferably, a rectangular groove is provided on the surface of the base, and the tooth plate is located on the inner wall of the rectangular groove.

[0014] A further technical solution is to ensure that the tooth plate always moves in the rectangular groove, thereby limiting the position of the mobile platform, preventing the tooth plate and the worm from being out of meshing state, and maintaining the stability of the meshing between the tooth plate and the worm.

[0017] Preferably, an anti-skid pad is fixedly connected to the surface of the clamping plate, and the anti-skid pad is made of rubber.

[0018] A further technical solution is that since the rubber material is easily deformed when squeezed, the deformed anti-skid pad will improve the fit between the clamping plate and the electrical equipment, thereby improving the friction between the clamping plate and the electrical equipment.

[0019] Preferably, the counterweight mechanism further comprises a plurality of placement grooves provided on the surface of the counterweight box, and the size of the placement grooves matches the size of the counterweight block, and the counterweight block and the counterweight box are detachably mounted.

[0020] A further technical solution is to add a counterweight block to the counterweight box to balance the center of gravity at both ends of the base, so as to prevent the base from tipping over when the base is carrying the power equipment and moving on an inclined road.

[0021] Preferably, a magnet plate is fixedly connected to the surface of the counterweight block, and an iron sheet is fixedly connected to the inner wall of the placement groove.

[0022] According to a further technical solution, the magnet plate and the iron sheet attract each other, so that the counterweight block is stably placed in the placement slot, thereby preventing the counterweight block from shaking in the placement slot.

[0023] Preferably, a cover plate is hingedly connected to the surface of the counterweight box, and a handle is fixedly connected to the surface of the cover plate.

[0024] A further technical solution is to use a cover plate to shield the opening of the placement slot at the upper end of the counterweight box during rainy weather, thereby effectively preventing rainwater from accumulating in the placement slot.

[0025] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a macro correction mechanism. When a small spacing error exists between the mounting components of the power equipment and the mounting frame during the installation of the power equipment, a one-way screw and a worm are used to push the mobile platform to move laterally and longitudinally, thereby fine-tuning the position of the power equipment above the lifting plate, thereby making it convenient for workers to install the power equipment on the mounting frame.

[0026] The present invention sets a limiting mechanism. When the power equipment is transported to the lifting plate, the second bidirectional screw is used to drive the clamping plates on both sides of the power equipment to move toward the power equipment, thereby clamping the power equipment, thereby fixing and limiting the power equipment on the lifting plate, so that the power equipment can be stably placed on the lifting plate.

[0027] The present invention provides a counterweight mechanism and adds a counterweight block to a counterweight box, so that the center of gravity of both ends of the base is balanced, so that when the base carrying the electric equipment moves on an inclined road, the base is prevented from tipping over.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The specific configuration and functions of the self-macro correction mechanism 4, the limit mechanism 5 and the counterweight mechanism 6 are described in detail below.

[0033] Reference Figures 2 to 6As shown, the macro correction mechanism 4 also includes a slide groove 401 opened on the surface of the mobile platform 2, and the slider 402 slides on the inner wall of the slide groove 401. The surface of the mobile platform 2 is fixedly connected with a tooth plate 406, and the worm 405 is rotatably connected to the base 1. The tooth plate 406 is meshingly connected with the worm 405. The ends of the worm 405 and the one-way screw 403 are detachably installed with a rocker 407, and the surface of the rocker 407 is fixedly connected with a rubber sleeve 408. When the power equipment needs to be installed at a higher position, the staff uses a special vehicle to lift the power equipment and place it on the lifting plate 3, and then transports the power equipment to the designated position through the mobile base 1. By energizing the servo motor 8, the servo motor 8 drives the first bidirectional screw 9 to rotate, and the first bidirectional screw When the rod 9 rotates, it will pull the two moving frames 10 to move relative to each other, so that the folding frame 11 is extended, and the power equipment on the lifting plate 3 is lifted to a higher position. Since there is still a certain distance between the power equipment and the mounting frame, according to the distance between the power equipment and the mounting frame, when it is necessary to move horizontally, the staff will then insert the plug 410 at the end of the rocker 407 into the slot 409 on the worm 405, and then the staff will use the rocker 407 to drive the worm 405 to rotate. When the worm 405 rotates, due to the meshing between the worm 405 and the tooth plate 406, the worm 405 rotates, and the tooth plate 406 is moved by the thrust of the worm teeth of the worm 405, thereby pushing the mobile platform 2 to move horizontally. At this time, the slider 402 is in The mobile platform 2 slides in the slide groove 401. When the mobile platform 2 needs to be moved forward, the staff inserts the plug 410 at the end of the rocker 407 into the slot 409 on the one-way screw 403 and rotates the one-way screw 403. The spiral line of the one-way screw 403 fits with the thread inside the base 1, so that the one-way screw 403 pushes the mobile platform 2 to move when it rotates. By continuously adjusting the position of the mobile platform 2, the position of the power equipment on the upper lifting plate 3 is fine-tuned. When there is a small spacing error between the mounting components of the power equipment and the mounting frame, the one-way screw 403 and the worm 405 are used to push the mobile platform 2 to move horizontally and vertically, so as to fine-tune the position of the power equipment above the lifting plate 3, thereby facilitating work. The personnel install the power equipment on the mounting frame. The end of the rocker 407 is fixedly connected with an insert block 410. The ends of the one-way screw 403 and the worm 405 are provided with slots 409. The size of the slot 409 matches the size of the insert block 410. Since the size of the insert block 410 on the rocker 407 is the same as the size of the slot 409 at the end of the worm 405 and the one-way screw 403, the worm 405 and the one-way screw 403 can be driven by using one drive assembly. By inserting the insert block 410 into the slot 409, the rocker 407 can be quickly connected with the one-way screw 403 and the worm 405, so that the rocker 407 can be shared. The insert block 410 and the slot 409 are a cross structure, which has a strong hardness and is more durable.Two guide rods 404 are fixedly connected to the surface of the slider 402, and the two guide rods 404 are slidably connected to the base 1. When the mobile platform 2 moves forward, the center of gravity of the mobile platform 2 changes, causing the mobile platform 2 to have a slight tilting force. By using the guide rods 404 for support, the mobile platform 2 is prevented from tilting and causing damage to the rotating assembly between the one-way screw 403 and the slider 402. A rectangular groove 411 is opened on the surface of the base 1, and the tooth plate 406 is located on the inner wall of the rectangular groove 411, so that the tooth plate 406 is always located in the rectangular groove 411 and moves, thereby limiting the position of the mobile platform 2, preventing the tooth plate 406 from being out of meshing with the worm 405, and maintaining the stability of the meshing between the tooth plate 406 and the worm 405.

[0034] In this embodiment, when it is necessary to install the power equipment at a higher position, the staff uses a special vehicle to lift the power equipment and place it on the lifting plate 3, and then transports the power equipment to the designated position through the mobile base 1, and energizes the servo motor 8, which drives the first bidirectional screw 9 to rotate. When the first bidirectional screw 9 rotates, it pulls the two mobile frames 10 to move relative to each other, so that the folding frame 11 extends, and the power equipment on the lifting plate 3 is lifted to a higher position. Since there is still a certain distance between the power equipment and the mounting frame, according to the distance between the power equipment and the mounting frame, when lateral movement is required, the staff then inserts the plug 410 at the end of the rocker 407 into the slot 409 on the worm 405, and then uses the rocker 407 drives the worm 405 to rotate. When the worm 405 rotates, due to the meshing between the worm 405 and the tooth plate 406, the worm 405 rotates while the tooth plate 406 is moved by the thrust of the worm teeth of the worm 405, thereby pushing the mobile platform 2 to move laterally. At this time, the slider 402 is located in the slide groove 401 of the mobile platform 2 and slides. When the mobile platform 2 needs to be moved forward, the staff inserts the plug 410 at the end of the rocker 407 into the slot 409 on the one-way screw 403 and rotates the one-way screw 403. The spiral of the one-way screw 403 fits with the thread inside the base 1, so that the one-way screw 403 pushes the mobile platform 2 to move when it rotates. By continuously adjusting the position of the mobile platform 2, the position of the power equipment on the upper lifting plate 3 is fine-tuned.

[0035] Reference Figure 7As shown, the limiting mechanism 5 also includes a guide groove 56 opened on the surface of the lifting plate 3, and the inner wall of the guide groove 56 is slidably connected to two moving blocks 52, and the two moving blocks 52 are threadedly connected to the second bidirectional screw 51, and the clamping plate 53 is fixedly connected to the moving block 52. The end of the second bidirectional screw 51 is fixedly connected with a twisting block 55. After the staff uses a special vehicle to lift the power equipment and place it on the lifting plate 3, the staff drives the second bidirectional screw 51 to rotate by rotating the twisting block 55. When the second bidirectional screw 51 rotates, the spiral thread on the second bidirectional screw 51 fits with the thread in the moving block 52, thereby driving the moving block 52 in the guide groove 56 to move. Since the spiral threads on both sides of the second bidirectional screw 51 are relative, the moving blocks 52 on both sides move relatively, so that the clamping plate 53 on the moving block 52 squeezes the power equipment, thereby The power equipment is fixed above the lifting plate 3. When the power equipment is transported to the lifting plate 3, the second bidirectional screw 51 is used to drive the clamping plates 53 on both sides of the power equipment to move toward the power equipment, so as to clamp the power equipment and fix the power equipment on the lifting plate 3. The surface of the clamping plate 53 is fixedly connected with an anti-skid pad 54, and the material of the anti-skid pad 54 is rubber. When the clamping plate 53 squeezes the power equipment, the anti-skid pad 54 on the clamping plate 53 will be deformed by force. Since the surface of the anti-skid pad 54 is uneven, the clamping force area is increased, thereby improving the stability of the clamping of the power equipment by the clamping plate 53. Since the rubber material is easily deformed when squeezed, the deformed anti-skid pad 54 will increase the fit between the clamping plate 53 and the power equipment, thereby increasing the friction between the clamping plate 53 and the power equipment.

[0036] In this embodiment, after the staff uses a special vehicle to lift the power equipment and place it on the lifting plate 3, the staff drives the second bidirectional screw 51 to rotate by rotating the screw block 55. When the second bidirectional screw 51 rotates, the spiral thread on the second bidirectional screw 51 fits with the thread in the moving block 52, thereby driving the moving block 52 in the guide groove 56 to move. Since the spiral threads on both sides of the second bidirectional screw 51 are relative, the moving blocks 52 on both sides move relatively, so that the splint 53 on the moving block 52 squeezes the power equipment, thereby fixing the power equipment above the lifting plate 3. When the splint 53 squeezes the power equipment, the anti-skid pad 54 on the splint 53 will be deformed by force. Since the surface of the anti-skid pad 54 is uneven, the clamping force area is increased, thereby improving the stability of the splint 53 clamping the power equipment.

[0037] Reference Figures 8 to 9As shown, the counterweight mechanism 6 also includes a plurality of placement grooves 62 opened on the surface of the counterweight box 61, and the size of the placement grooves 62 is adapted to the size of the counterweight blocks 65. The counterweight blocks 65 and the counterweight box 61 are detachably installed. After the electric equipment is lifted and placed on the lifting plate 3, the staff puts the counterweight blocks 65 into the placement grooves 62 in the counterweight box 61. According to the weight of the electric equipment, different numbers of counterweight blocks 65 can be put in to match the weight of the front and rear ends of the base 1, so that when the base 1 is moved, especially when it is moved on an inclined road, the center of gravity of the base 1 is stable, which effectively avoids the transport vehicle from tipping over due to an unstable center of gravity. The addition of counterweight blocks 65 to the counterweight box 61 balances the center of gravity of both ends of the base 1, so that when the base 1 carries the electric equipment and moves on an inclined road, it is avoided In order to prevent the base 1 from tipping over, the surface of the counterweight 65 is fixedly connected with a magnet plate 67, and the inner wall of the placement groove 62 is fixedly connected with an iron sheet 66. When the counterweight 65 is placed in the placement groove 62, since the bottom of the counterweight 65 contains a magnet plate 67, the magnet plate 67 is attracted to the iron sheet 66 in the placement groove 62, so that the counterweight 65 is not easy to shake in the placement groove 62. The magnet plate 67 and the iron sheet 66 are attracted to each other, so that the counterweight 65 is stably placed in the placement groove 62 to prevent the counterweight 65 from shaking in the placement groove 62. The surface of the counterweight box 61 is hingedly connected with a cover plate 63, and the surface of the cover plate 63 is fixedly connected with a handle 64. In rainy weather, the cover plate 63 is used to cover the opening of the placement groove 62 at the upper end of the counterweight box 61, which effectively prevents rainwater from accumulating in the placement groove 62.

[0038] In this embodiment, after the power equipment is lifted and placed on the lifting plate 3, the staff puts the counterweight block 65 into the placement slot 62 in the counterweight box 61. When the counterweight block 65 is placed in the placement slot 62, since the bottom of the counterweight block 65 contains a magnet plate 67, the magnet plate 67 is attracted to the iron sheet 66 in the placement slot 62, so that the counterweight block 65 is not easy to shake in the placement slot 62. According to the weight of the power equipment, different numbers of counterweight blocks 65 can be put in to match the weight of the front and rear ends of the base 1, so that when the base 1 is moved, especially when it is moved on an inclined road, the center of gravity of the base 1 is stable, effectively avoiding the transport vehicle from tipping over due to unstable center of gravity.
