Description

Technical Field

[0001] This application relates to the field of power equipment construction technology, specifically a high-voltage distribution cabinet installation device for power construction. Background Technology

[0002] High-voltage switchgear is a key piece of equipment in power systems, used for switching, control, and protection in power generation, transmission, distribution, energy conversion, and consumption. During the construction of power transmission and distribution projects, a large number of high-voltage switchgear need to be installed in designated locations and secured with bolts and other fasteners. High-voltage switchgear is large and heavy, and its installation quality directly affects the safe operation of power equipment and the stability and reliability of the power system. Therefore, the installation of high-voltage switchgear is crucial in power construction, requiring high levels of installation accuracy, construction efficiency, and operational safety.

[0003] In traditional installation processes, high-voltage switchgear is moved and lifted manually, with workers placing the heavy cabinets on steel supports for securing them. Due to the cabinets' weight and height, and given limited space, installation work is labor-intensive, inefficient, and presents challenges in ensuring reliability and worker safety. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this application provides a high-voltage distribution cabinet installation device for power construction, which aims to reduce labor intensity and improve work efficiency to a certain extent.

[0005] This application is achieved through the following technical solution: A high-voltage distribution cabinet installation device for power construction, the installation device comprising: an installation cabinet, which is movably installed, and the installation cabinet includes a cabinet body, the front and bottom of the cabinet body being open and the interior being hollow for accommodating the distribution cabinet; an adjustment component including a hoisting mechanism, the hoisting mechanism including a hanger, hooks, and a lifting module, wherein: the hanger is slidably installed in the cabinet body, a plurality of hooks are connected to the bottom of the hanger around the central axis of the hanger, the lifting module is connected to the inner wall of the cabinet body, the lifting module has a telescopic end that moves vertically reciprocating, and the telescopic end of the lifting module is connected to the hanger.

[0006] In some embodiments, the bottom of the hanger is provided with two intersecting guide grooves along the diagonal, and each guide groove is provided with two hooks, which can reciprocate within the guide grooves.

[0007] In some implementations, the lifting module is a ball screw assembly; two lifting modules are provided, and the two lifting modules are respectively located on opposite side walls of the cabinet.

[0008] In some implementations, the lifting module further includes a slide rail disposed on the inner wall of the cabinet, and the side of the hanger is provided with a slide groove, through which the slide rail slides.

[0009] In some implementations, limit blocks are provided at both ends of the slide rail.

[0010] In some embodiments, the adjusting assembly further includes a backstop mechanism, which is configured one-to-one with each slide rail. The backstop mechanism includes a carrier and corresponding pulleys, a first connecting rod, an elastic element, a transmission block, a first gear, a second gear, a second connecting rod, and a locking wheel. The carrier is located at the bottom of the hanger, and the two pulleys are located on opposite sides of the width direction of the corresponding slide rail. One end of the first connecting rod is connected to the pulley, and the other end of the first connecting rod is located within the carrier. The first gear is located within the carrier, is annular, and coaxially spaced outside the other end of the first connecting rod. The first gear has teeth on both its inner and outer sides. A transmission block is positioned within the first gear. One end of the transmission block has teeth, and a sliding hole is located in the middle of the transmission block. The sliding hole is radially positioned along the first gear. The other end of the first connecting rod is slidably positioned within the sliding hole. One end of the elastic element is connected to the other end of the first connecting rod. The elastic element extends along the length of the sliding hole, and the other end of the elastic element is connected to the toothed end of the sliding hole away from the transmission block. The second gear is rotatably connected to the carrier via one end of the second connecting rod. The second gear meshes with the first gear. The locking wheel is positioned on the side of the corresponding slide rail, and the other end of the second connecting rod is eccentrically connected to the locking wheel.

[0011] In some implementations, the locking wheel is provided with teeth on its circumference.

[0012] In some embodiments, the anti-reverse mechanism further includes a ratchet and pawl assembly, wherein the ratchet of the ratchet and pawl assembly is coaxially connected to the side of the second gear, one end of the pawl of the ratchet and pawl assembly is rotatably connected to the carrier, and the other end of the pawl engages with the ratchet.

[0013] In some implementations, the adjustment assembly further includes a stabilizing mechanism, which includes a support plate, a telescopic rod, and a pressure equalizing plate, wherein: the top of the support plate is fixedly connected to the hanger, the telescopic rod is provided on the inner side of the bottom of the support plate, and the pressure equalizing plate is provided at the telescopic end of the telescopic rod.

[0015] The high-voltage switchgear installation device provided in this application allows for the connection of hooks on the hanger to lifting rings on the high-voltage switchgear. Activating the lifting module lowers its telescopic end, pushing the hanger to slide smoothly down the inner wall of the switchgear. Simultaneously, the hanger lowers all hooks at the bottom until the bottom of the hook is below the upper surface of the lifting ring at the top of the switchgear. The operator then operates the lifting ring to screw it into the corresponding ring. Activating the lifting module again causes its telescopic end to rise at a set speed. The hanger raises the switchgear synchronously, slowly lifting the entire high-voltage switchgear off the ground. The switchgear can then be moved as a whole, transferring the suspended switchgear to its final installation position, ready for the next step of placement. Controlling the telescopic end of the lifting module to descend at a set speed lowers the suspended switchgear to its corresponding installation position. Finally, disconnecting the hanger from the lifting rings on the switchgear and removing the installation device reduces labor and improves work efficiency through mechanized operation.

Detailed Implementation

[0018] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Figure 1 This application shows a schematic diagram of the structure of a high-voltage distribution cabinet installation device for power construction in one or more embodiments, combined with... Figure 1 A high-voltage distribution cabinet installation device for power construction includes an installation cabinet 100 and an adjustment component 200. The installation cabinet 100 is movable and includes a cabinet body 110 with open front and bottom and hollow interior for accommodating the distribution cabinet. The adjustment component 200 includes a hoisting mechanism 210, a stabilizing mechanism 230, and a guiding mechanism 240. The hoisting mechanism 210 is located inside the installation cabinet 100, the stabilizing mechanism 230 is located at the bottom of the hoisting mechanism 210, and the guiding mechanism 240 is located on the inner wall of the installation cabinet 100.

[0020] In this application, the installation cabinet 100 can accommodate a high-voltage distribution cabinet to be installed. By operating the moving installation cabinet 100, the distribution cabinet to be installed is accommodated inside the installation cabinet 100, and the distribution cabinet to be installed is connected to the hoisting mechanism 210 of the adjusting component 200. By operating the hoisting mechanism 210, the distribution cabinet is lifted to a certain height. The installation cabinet 100 is moved again to a position above the steel support. After the high-voltage distribution cabinet is aligned with the steel support, the high-voltage distribution cabinet is lowered using the hoisting mechanism 210 of the adjusting component 200. After the high-voltage distribution cabinet is placed on the steel support and the installation is completed, the connection between the hoisting mechanism 210 and the high-voltage distribution cabinet is disconnected, and the installation device is removed. During the process of the hoisting mechanism 210 raising and lowering the distribution cabinet, the stabilizing mechanism 230 and the guiding mechanism 240 of the adjusting component 200 are used to adjust the raising and lowering posture of the high-voltage distribution cabinet to prevent it from shaking and causing damage from collisions, thereby reducing labor and improving work efficiency.

[0021] Combination Figure 1 In some embodiments, the installation cabinet 100 includes a cabinet body 110, casters 120, and handrails 130. Four casters 120 are provided at the four corners of the bottom of the cabinet body 110, and a handrail 130 is provided on the side of the cabinet body 110 away from the opening. The handrails 130 can push the installation device so that the open side of the installation cabinet 100 faces and covers the distribution cabinet to be installed. The casters 120 allow the installation device to be pushed with relatively little force even after the high-voltage distribution cabinet is mounted, effectively reducing workload. The casters 120 have a braking function to maintain a fixed state when the installation cabinet 100 is fixed.

[0022] Figure 2 It shows Figure 1 A schematic diagram of the lifting mechanism 210 and the stabilizing mechanism 230. Figure 3 It shows Figure 1 A schematic diagram of the power unit of the hoisting mechanism 210 and the guiding mechanism 240. Figure 4 It shows Figure 1 A structural diagram from an upward-looking perspective, combined with Figure 2-4In some implementations, the hoisting mechanism 210 includes a hanger 211, hooks 212, and a lifting module. The hanger 211 is slidably disposed within the cabinet 110. Multiple hooks 212 are connected to the bottom of the hanger 211 around its central axis. The lifting module is connected to the inner wall of the cabinet 110 and has a telescopic end that reciprocates vertically. The telescopic end of the lifting module is connected to the hanger 211. In a specific implementation, the hooks 212 on the hanger 211 can be connected to the lifting rings on the high-voltage distribution cabinet. When the lifting module is activated, the telescopic end of the lifting module descends, pushing the hanger 211 so that it slides smoothly down the inner wall of the cabinet 110. At this point, the hanger 211 lowers all the hooks 212 at its bottom simultaneously until the bottom of the hook 212 is lower than the upper surface of the top lifting ring of the distribution cabinet. The operator then operates the lifting ring to screw it into the corresponding lifting ring. The lifting module is then restarted, and its extension end continues to rise at a set speed (e.g., 0.1~0.3 m / s). The hanger 211 raises the cabinet 110 simultaneously, slowly lifting the entire high-voltage distribution cabinet off the ground. Finally, the cabinet 110 can be moved as a whole, transferring the suspended distribution cabinet to its final installation position, ready for the next step of placement and installation. The extension end of the lifting module is lowered at a set speed to place the suspended distribution cabinet into the corresponding installation position. Then, the connection between the hanger 211 and the lifting ring on the distribution cabinet is released, and the installation device is removed.

[0023] In some embodiments, the bottom of the hanger 211 is provided with two intersecting guide grooves 2111 along the diagonal, and each guide groove 2111 is provided with two hooks 212, which can reciprocate within the guide groove 2111. This configuration allows for compatibility with various specifications of high-voltage distribution cabinets by changing the position of the hooks 212 within the guide groove 2111.

[0024] In some embodiments, the lifting module includes a lead screw seat 213, a lead screw 214, a lead screw nut 215, a motor seat 216, and a motor 217. The lead screw nut 215 is located on the side of the hanger 211 away from the opening. The lead screw 214 is located inside the lead screw nut 215. The lead screw seat 213 is located at the end of the lead screw 214. The motor 217 is located on the side of the lead screw 214 away from the hanger 211. The motor seat 216 is located on the side of the motor 217 closest to the lead screw 214. That is, the lifting module used in this application is a ball screw pair, which has the characteristics of stable and reliable transmission. Of course, in other embodiments, the lifting module can also use a hydraulic cylinder or other mechanism; this application does not impose any limitations on this.

[0025] In some embodiments, two lifting modules are provided, which are located on opposite side walls of the cabinet 110 to provide a stable driving force to drive the hanger 211 to rise and fall.

[0026] In some embodiments, the opposite side walls of the cabinet 110 are provided with receiving grooves 111 for accommodating the lead screw 214, so that the lead screw 214 does not protrude from the inner wall of the cabinet 110, thereby adapting the hanger 211 to the cross section of the cabinet 110, so as to limit the lifting and lowering of the hanger 211 by the inner wall of the cabinet 110, and prevent the hanger 211 from shaking when lifting and lowering.

[0027] In some embodiments, the lifting module further includes a slide groove 218 and a slide rail 219. The side of the hanger 211 is provided with a slide groove 218, and the slide rail 219 is provided on the inner wall of the cabinet 110. The slide rail 219 slides through the slide groove 218 to guide and restrict the movement of the hanger 211, ensuring that the movement of the hanger 211 is always perpendicular to the ground. In a specific implementation, two opposing guide grooves 2111 are provided on the back of the hanger 211, and correspondingly, two corresponding slide rails 219 are also provided on the inner wall of the cabinet 110.

[0028] In some embodiments, limit blocks 2191 are provided at both ends of the slide rail 219 to limit the range of movement of the hanger 211 and prevent the hanger 211 from moving excessively.

[0029] The lifting module of this application uses a ball screw pair. The screw nut 215 provides power for the lifting of the hanger 211. The screws 214 on both sides rotate simultaneously to ensure that the hanger 211 can be lifted and lowered smoothly. The screw nut 215 and the screw 214 have a self-locking function. In addition, with the anti-backward mechanism 220 mentioned below, it ensures that the hanger 211 and the power distribution cabinet remain suspended in abnormal working conditions such as unexpected power outages to avoid the risk of falling. The screw seats 213 at both ends of the screw 214 fix the screw 214 to the mounting cabinet 100. The motor 217 on one side of the screw 214 provides power for the rotation of the screw 214. The motor 217 is also fixed to the mounting cabinet 100 through the motor seat 216. The sliding groove 218 and the sliding rail 219 of the hanger 211 cooperate to guide and restrict the movement of the hanger 211, ensuring that the movement of the hanger 211 is always perpendicular to the ground.

[0030] Figure 5 It shows Figure 1 A schematic diagram of the anti-reverse mechanism 220. Figure 6 It shows Figure 1 A schematic diagram showing the connection between the anti-reverse mechanism 220 and the slide rail 219, combined with... Figure 5-6In some embodiments, the adjustment assembly 200 further includes a backstop mechanism 220, which is configured one-to-one with the slide rails 219. The backstop mechanism 220 includes a carrier 221 and corresponding pulleys 222, a first connecting rod 223, an elastic element 224, a transmission block 225, a first gear 226, a second gear 227, a second connecting rod 228, and a locking wheel 229. The carrier 221 is disposed at the bottom of the hanger 211. The two pulleys 222 are disposed on both sides of the corresponding slide rails 219 in the width direction. One end of the first connecting rod 223 is connected to the pulley 222, and the other end of the first connecting rod 223 is disposed inside the carrier 221. The first gear 226 is disposed inside the carrier 221. The first gear 226 is annular and coaxially spaced outside the other end of the first connecting rod 223. Both the inner and outer sides of the first gear 226 have The transmission block 225 is fitted with a toothed gear within the first gear 226. One end of the transmission block 225 has a toothed gear, and a sliding hole 2251 is provided in the middle of the transmission block 225. The sliding hole 2251 is arranged radially along the first gear 226. The other end of the first connecting rod 223 is slidably fitted in the sliding hole 2251. One end of the elastic element 224 is connected to the other end of the first connecting rod 223. The elastic element 224 extends along the length of the sliding hole 2251, and the other end of the elastic element 224 is connected to the toothed end of the sliding hole 2251 away from the transmission block 225. The second gear 227 is rotatably connected to the carrier 221 through one end of the second connecting rod 228. The second gear 227 meshes with the first gear 226. The locking wheel 229 is provided on the side of the corresponding slide rail 219, and the other end of the second connecting rod 228 is eccentrically connected to the locking wheel 229.

[0031] In practice, the hanger 211 drives the carrier 221 to move normally along the slide rail 219, and the pulley 222 rolls with the slide rail 219, driving the first connecting rod 223 to rotate synchronously in the sliding hole 2251 of the transmission block 225. At this time, the elastic element 224 is in its natural length or slightly pre-compressed state. Since there is no abnormal acceleration, the first connecting rod 223 does not push the meshing end of the transmission block 225 towards the inner teeth of the first gear 226. The transmission block 225 and the inner ring of the first gear 226 maintain a clearance fit, the first gear 226 is stationary, the second gear 227 and the eccentrically positioned second connecting rod 228 do not rotate, the locking wheel 229 maintains a safe clearance with the side wall of the slide rail 219, and the hanger 211 moves normally. When the hanger 211 is accidentally dropped, the slide rail 219 generates an instantaneous reverse acceleration relative to the pulley 222. The end of the first connecting rod 223 is driven by the slide rail 219 along with the pulley 222. The meshing end of the transmission block 225 moves rapidly towards the inside of the first gear 226 in the direction of the sliding hole 2251, and compresses and squeezes. The elastic element 224 engages with the inner teeth of the first gear 226 at the moment the meshing end of the transmission block 225 is engaged. The transmission block 225 locks with the inner ring of the first gear 226, driving the first gear 226 to rotate. Its outer teeth drive the second gear 227, which meshes with it, to begin rotating. The second gear 227 drives the second connecting rod 228, which is fixedly connected to it, to rotate. Since the other end of the second connecting rod 228 is eccentrically connected to the locking wheel 229, the rotational motion of the second connecting rod 228 is transformed into the radial oscillation of the locking wheel 229. As the second gear 227 continues to rotate, the eccentric connection between the second connecting rod 228 and the locking wheel 229 pushes the locking wheel 229, causing its outer surface to tightly press against the side plane of the slide rail 219, thus transforming into a strong sliding friction force. The direction of this friction force is completely opposite to the backward direction of the hanger 211, instantly preventing the hanger 211 from continuing to move backward. Furthermore, the ratchet on the other side of the second gear 227 relative to the second connecting rod 228 prevents the locking wheel 229 from rebounding and reducing the locking force, thus keeping the locking wheel 229 locked and maintaining the braking state without external power. When the hanger 211 comes to a complete stop, the compressed elastic element 224 releases its elastic potential energy, pushing the first connecting rod 223 to slide in the opposite direction within the sliding hole 2251, causing its meshing end to disengage from the internal teeth of the first gear 226. The first gear 226 resumes free rotation, while the second gear 227 remains locked due to the ratchet, preventing secondary falls and improving the reliability of the device. After maintenance of the device is completed, the carrier 221 needs to be opened to manually release the ratchet and reset the locking wheel 229, returning the entire mechanism to a free sliding state and completing a full work cycle.

[0032] In some embodiments, the locking wheel 229 is also provided with teeth on its periphery, so that after the locking wheel 229 contacts the slide rail 219, the tooth tips will embed into the surface of the side wall of the slide rail 219, thereby increasing the friction of the locking wheel 229 and preventing the phenomenon of "slippage failure" during emergency braking.

[0033] In some embodiments, the anti-reverse mechanism 220 further includes a ratchet and pawl assembly 2271. The ratchet of the ratchet and pawl assembly 2271 is coaxially connected to the side of the second gear 227. One end of the pawl of the ratchet and pawl assembly 2271 is rotatably connected to the carrier 221, and the other end of the pawl engages with the ratchet. During normal operation of the lifting module, the ratchet and the second gear 227 rotate synchronously. When the lifting module operates abnormally, and the hanger 211 is kept in a braking state by the anti-reverse mechanism 220, the second gear 227 remains locked due to the ratchet, preventing secondary falls and improving the reliability of the device. After maintenance of the device is completed, the pawl can be released from locking the ratchet. Exemplarily, the ratchet and pawl assembly 2271 is disposed within the carrier 221; in other configurations, the ratchet and pawl assembly 2271 is disposed outside the carrier 221.

[0034] Combination Figure 2 In some embodiments, the stabilizing mechanism 230 includes a support plate 231, a telescopic rod 232, and a pressure equalizing plate 233. The top of the support plate 231 is fixedly connected to the hanger 211, and the telescopic rod 232 is provided on the inner side of the bottom of the support plate 231. The telescopic end of the telescopic rod 232 is provided with the pressure equalizing plate 233.

[0035] The support plate 231 provides support for the working structure. The telescopic rod 232 set on the support plate 231 can fit the pressure equalizing plate 233 against the cabinet wall of the high voltage distribution cabinet. The high voltage distribution cabinet is kept stable by the telescopic rods 232 on both sides and the pressure equalizing plate 233. The surface of the pressure equalizing plate 233 is provided with a protective pad 234 to protect the surface of the high voltage distribution cabinet.

[0036] In some embodiments, the stabilizing mechanism 230 further includes a protective pad 234, which is provided on the inner side of the pressure equalizing plate 233. The protective pad 234 is made of a flexible material to reduce wear on the surface of the distribution cabinet.

[0037] In practice, stabilizing mechanisms 230 are installed on the left and right side walls of the hanger 211 facing the cabinet 110. The telescopic rods 232 of the stabilizing mechanisms 230 can be hydraulic cylinders or motors. During the lifting process, the telescopic rods 232 maintain a continuous clamping force, ensuring that the pressure equalizing plate 233 remains in close contact with the cabinet wall, effectively attenuating lateral sway caused by center of gravity shift or inertia, and ensuring that the distribution cabinet rises smoothly in a vertical posture. After the distribution cabinet is lifted to the target suspension height and the transfer is completed, the telescopic rods 232 retract in the opposite direction, causing the pressure equalizing plate 233 and the protective pad 234 to detach from the left and right cabinet walls of the distribution cabinet, completely releasing the clamping constraints. Subsequently, the stabilizing mechanisms 230 follow the hanger 211 to rise unloaded to the storage height at the top of the cabinet 110, awaiting the next lifting command.

[0038] Figure 3 It shows Figure 1A schematic diagram of the power unit of the hoisting mechanism 210 and the guiding mechanism 240, combined with... Figure 3 In some embodiments, the adjustment assembly 200 further includes a guide mechanism 240, which includes a telescopic slide 241, a guide plate 242, and ball bearings 243. Specifically, telescopic slides 241 are provided on both inner walls of the cabinet 110, and a guide plate 242 is provided on the other side of the telescopic slide 241. At least a portion of the inner side of the guide plate 242 is provided with ball bearings 243. Exemplarily, the telescopic slide 241 can be a hydraulic cylinder or a motor, and multiple ball bearings 243 are provided at both ends of the inner side of the guide plate 242.

[0039] When there is an already installed high-voltage distribution cabinet, one end of the guide plate 242 can be attached to the cabinet wall of the high-voltage distribution cabinet to be installed by using the telescopic slides 241 on both sides of the cabinet 110, and then the other end of the guide plate 242 can be attached to the already installed high-voltage distribution cabinet. By pushing the cabinet 110, the high-voltage distribution cabinet to be installed can be pushed horizontally and attached to the already installed high-voltage distribution cabinet to complete the quick positioning. The ball bearings 243 set on the surface of the guide plate 242 can reduce frictional resistance and protect the surface of the high-voltage distribution cabinet.

[0040] Through the coordination of the aforementioned mechanisms, this high-voltage distribution cabinet installation device for power construction can effectively reduce workload and improve work efficiency by reducing handling and positioning time.
