A power grid power screen cabinet installation transfer device

Abstract

This invention discloses a power grid power cabinet installation and transfer device, belonging to the field of power cabinet installation technology. It includes a main body mechanism for transferring the power cabinet, with an adjustment mechanism for adapting to power cabinets of different sizes and a leveling mechanism for leveling the power cabinet. By setting a leveling mechanism on the support arm and cooperating with the support leg module, this invention achieves independent leveling of the four corners of the power cabinet. After the cabinet is positioned, the leveling feet contact the ground, and the support motor drives the inner rotating cylinder to rotate, using threaded transmission to drive the upper top plate to rise, thereby precisely lifting each corner of the cabinet. This allows for precise compensation for cabinet tilt caused by uneven ground or differences in channel steel height during installation, ensuring the cabinet is in an absolutely level state. This effectively avoids problems such as equipment stress and uneven cabinet gaps caused by uneven installation, improving installation quality.

Description

Technical Field

[0001] This invention relates to the field of power cabinet installation technology, and in particular to a power grid power cabinet installation and transfer device. Background Technology

[0002] In the construction and maintenance of power systems, the installation and transportation of power distribution cabinets is a crucial step. Power distribution cabinets are typically large and heavy, integrating sophisticated electrical components, requiring high installation accuracy and safety. Currently, the installation and transportation of power distribution cabinets mainly rely on the following methods: First, using general lifting equipment such as forklifts and cranes. While these devices can handle heavy loads, their structure limits their flexibility in confined spaces like distribution rooms and substations, and their positioning accuracy is relatively low. Placing the cabinets on pre-embedded fixed channel steel often requires significant manual assistance for alignment and fine-tuning. Second, using traditional handcarts with pry bars and rollers. This method is extremely labor-intensive, inefficient, and prone to tilting and collisions due to uneven force during handling and installation, posing safety hazards and potentially damaging the delicate components inside. Third, using specialized cabinet handling trolleys, but existing equipment typically has limited functionality, only providing basic load-bearing and movement capabilities.

[0003] During installation, existing technologies mainly suffer from the following technical problems: poor adaptability; different models of power cabinets and the dimensions of fixed channel steel at installation sites vary, making it difficult for existing handling devices to quickly and accurately adjust their load-bearing mechanisms to adapt to different widths and positions, resulting in alignment difficulties and low installation efficiency; lack of leveling function; due to unevenness of the ground or fixed channel steel at the construction site, the cabinet is prone to tilting after installation, and existing devices cannot accurately level the cabinet during installation, often requiring manual leveling using shims, which is cumbersome and difficult to guarantee accuracy, affecting the long-term operational stability and merging quality of the cabinet; difficulty in installation alignment and merging; when placing the cabinet on the fixed channel steel and merging it with adjacent cabinets, existing devices cannot achieve precise positioning and tight fit, often requiring multiple adjustments or external force to strike, which can easily damage the surface of the cabinet.

[0004] Therefore, developing a power grid power cabinet installation and transfer device that can adapt to different sizes and specifications, has precise leveling function, and can achieve accurate alignment and paralleling is of great significance for improving the installation efficiency, quality and safety of power cabinets. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a power grid power cabinet installation and transfer device, comprising a main body for transferring the power cabinet, the main body including a mobile vehicle, and the main body being provided with an adjustment mechanism for adapting to power cabinets of different sizes and a leveling mechanism for leveling the power cabinet; The main structure also includes a support frame fixedly installed on the mobile vehicle body, a lifting bracket slidably installed on the support frame, and an adjustment mechanism including two support arms slidably installed on the lifting bracket.

[0006] Furthermore, the main structure also includes a lifting motor fixedly installed inside the mobile vehicle body. A motor wheel is fixedly installed on the motor shaft of the lifting motor. A lower transmission wheel and an upper transmission wheel are rotatably installed on the vertical support. A vertical transmission belt is wound around the lower transmission wheel and the upper transmission wheel. A lifting transmission belt is wound around the lower transmission wheel and the motor wheel. A connecting plate is fixedly installed on the vertical transmission belt. The connecting plate is fixedly installed with the lifting bracket.

[0007] Furthermore, the main structure also includes external drive wheels rotatably mounted on both sides of the mobile vehicle body, an internal drive shaft rotatably mounted inside the mobile vehicle body, an internal gear and an external drive wheel fixedly mounted on the internal drive shaft, a walking track wrapped around the external drive wheel and the external drive wheel, a walking motor fixedly mounted inside the mobile vehicle body, a motor gear fixedly mounted on the motor shaft of the walking motor, and the motor gear meshing with the internal gear.

[0008] Furthermore, the main structure also includes two sponge blocks fixedly installed on the lifting bracket, two electric cylinders fixedly installed on the lifting bracket, and a counterweight fixedly installed on the moving vehicle body.

[0009] The walking motor drives the motor gear to rotate, which in turn drives the internal gear, internal drive shaft, and outer drive wheel to rotate. The outer drive wheel then drives the walking track to rotate, enabling the device to move. The mobile vehicle also has a steering mechanism to control the direction of travel. The lifting motor drives the motor wheel to rotate, which in turn drives the lower drive wheel via the lifting transmission belt. The lower drive wheel drives the vertical transmission belt to rotate, which in turn drives the connecting plate to rise and fall, thereby causing the lifting bracket to rise and fall along the vertical support. The device first moves to the power supply cabinet to be transported. The support arm and positioning arm are then inserted under the power supply cabinet, which is positioned on the supporting rollers. Then, the lifting bracket rises, lifting the power panel cabinet from the ground. The device then moves the power panel cabinet to the fixed channel steel to be installed. The moving vehicle then moves between the two fixed channel steels and moves the power panel cabinet to the installation position. The lifting bracket then descends, placing the power panel cabinet on the fixed channel steel. The mounting holes of the power panel cabinet fall onto the anchor bolts on the fixed channel steel. If it is necessary to install two power panel cabinets tightly, the newly installed power panel cabinet is placed next to the already installed power panel cabinet, and then the electric cylinder is extended to make the two power panel cabinets fit tightly before fixing the newly installed power panel cabinet.

[0010] Furthermore, the adjustment mechanism also includes an internal adjusting screw rotatably mounted on the lifting bracket. The internal adjusting screw has two threads in opposite directions. An internal adjusting gear is fixedly mounted on the internal adjusting screw. The internal adjusting screw and the support arm form a threaded transmission. A central rotating gear is rotatably mounted inside the moving vehicle body. The central rotating gear meshes with the internal adjusting gear. An adjustment motor is fixedly mounted inside the moving vehicle body. An adjustment gear is fixedly mounted on the motor shaft of the adjustment motor. The adjustment gear meshes with the central rotating gear.

[0011] Furthermore, the adjustment mechanism also includes two positioning arms slidably mounted on the lifting bracket. Multiple supporting rollers are rotatably mounted on the positioning arms. A positioning rod is fixedly mounted on the outside of the positioning arms. An external adjusting screw is rotatably mounted inside the lifting bracket. The external adjusting screw has two sections of threads in opposite directions. An external adjusting gear is fixedly mounted on the external adjusting screw. The external adjusting gear meshes with the internal adjusting gear. The positioning arms and the external adjusting screw form a threaded transmission.

[0012] The adjusting motor drives the adjusting gear to rotate, which in turn drives the intermediate gear to rotate. The intermediate gear then drives the inner adjusting gear and the inner adjusting screw to rotate. The inner adjusting gear drives the outer adjusting gear and the outer adjusting screw to rotate. The inner adjusting screw drives the two support arms to slide inward or outward simultaneously, and the outer adjusting screw drives the two positioning arms to slide inward or outward simultaneously. First, the device moves between the two fixed channel steels, causing the two positioning arms and the support arms to move outward. When both positioning rods are in contact with the fixed channel steels, the positioning arms and the support arms are in the appropriate positions, thus realizing the adjustment of the positions of the positioning arms and the support arms according to the fixed channel steels and power cabinets of different sizes.

[0013] Furthermore, the leveling mechanism includes multiple support motors fixedly mounted on the support arm. Each support arm has two mating gears and two intermediate wheels rotatably mounted on it. The support motors drive the intermediate wheels to rotate via a front transmission belt, and the intermediate wheels drive the mating gears to rotate via a rear transmission belt.

[0014] Furthermore, the leveling mechanism also includes an opening at the end of the support arm, in which a foot module is placed. The foot module includes an inner rotating cylinder, which is placed in the opening at the end of the support arm. An upper top plate and an external gear are fixedly installed on the inner rotating cylinder. The external gear meshes with the mating gear. An inner screw is rotatably installed inside the inner rotating cylinder, and a leveling foot is fixedly installed below the inner screw. The inner screw and the inner rotating cylinder form a threaded transmission.

[0015] After the lifting bracket lowers and places the power supply cabinet on the fixed channel steel, the leveling feet are in contact with the ground. At this time, the support motor drives the intermediate wheel to rotate via the front drive belt. The intermediate wheel drives the mating gear to rotate via the rear drive belt. The mating gear drives the external gear and the inner rotating cylinder to rotate. Since the leveling feet are now in contact with the ground, the inner rotating cylinder rotates. Through the threaded transmission between the inner rotating cylinder and the inner screw, the inner rotating cylinder is driven to rise, thus placing the upper top plate under the power supply cabinet. When the upper top plate contacts the lower surface of the power supply cabinet, the upper top plate continues to rise, driving the power supply cabinet to rise. The four corners of the bottom of the power supply cabinet are leveled through the four support leg modules. After the four corners of the power supply cabinet are leveled, the power supply cabinet is manually fixed to the anchor bolts on the fixed channel steel. Then the device is removed from the power supply cabinet, the support arm and positioning arm are pulled out from under the power supply cabinet, and the support leg modules are detached from the support arm and remain under the power supply cabinet.

[0016] The beneficial effects of this invention compared with the prior art are: (1) By setting an adjustment mechanism, this invention uses an adjustment motor to drive the inner and outer adjustment screws to rotate synchronously, which can accurately control the two support arms and the two positioning arms to slide inward or outward at the same time. During operation, through the contact feedback between the positioning rod and the fixed channel steel on site, the support arms and positioning arms can be quickly adjusted to a suitable position that matches the spacing of the channel steel, so that the device can flexibly adapt to fixed channel steels of different widths and power cabinets of different sizes, without the need for manual adjustment or replacement of parts, thus improving the versatility of the device and the convenience of on-site operation; (2) By setting a leveling mechanism on the support arm and cooperating with the support leg module, this invention realizes independent leveling of the four corners of the power cabinet. When the cabinet is in place, the leveling feet contact the ground, the support motor drives the inner rotating cylinder to rotate, and the screw drive drives the upper plate to rotate. The device can accurately lift each corner of the cabinet, and can accurately compensate for the tilt of the cabinet caused by uneven ground or different channel steel height during the installation process, ensuring that the cabinet is in an absolutely horizontal state. This effectively avoids problems such as equipment stress and uneven cabinet gaps caused by uneven installation, and improves the installation quality. (3) The support module of this invention adopts a connection method that can be detached from the support arm. After leveling, the support module rises with the inner rotating cylinder to lift the cabinet. At this time, the support module is detached from the support arm at the opening and is retained at the bottom of the cabinet as a permanent or temporary support. This allows the support arm to be easily pulled out from under the cabinet after the device completes the cabinet placement and leveling. This avoids disturbance or displacement of the already positioned cabinet when the load-bearing component is removed, and realizes a smooth transition of the cabinet from transportation, leveling to final placement, further ensuring installation accuracy and operational safety.

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0029] Example: Reference Figures 1-10 A power grid power cabinet installation and transfer device includes a main body for transferring the power cabinet 4. The main body includes a mobile vehicle 101. The main body is provided with an adjustment mechanism for adapting to power cabinets 4 of different sizes and a leveling mechanism for leveling the power cabinet 4. The main structure also includes a support bracket 103 fixedly installed on the mobile vehicle body 101, a lifting bracket 104 slidably installed on the support bracket 103, and an adjustment mechanism including two support arms 201 slidably installed on the lifting bracket 104.

[0030] like Figure 4 , Figure 5As shown, the main structure also includes a lifting motor 106 fixedly installed in the mobile vehicle body 101. A motor wheel 107 is fixedly installed on the motor shaft of the lifting motor 106. A lower transmission wheel 109 and an upper transmission wheel 111 are rotatably installed on the vertical support 103. A vertical transmission belt 112 is wound around the lower transmission wheel 109 and the upper transmission wheel 111. A lifting transmission belt 108 is wound around the lower transmission wheel 109 and the motor wheel 107. A connecting plate 110 is fixedly installed on the vertical transmission belt 112. The connecting plate 110 is fixedly installed with the lifting bracket 104.

[0031] For example Figure 4 , Figure 5 As shown, the main mechanism also includes external drive wheels 118 rotatably mounted on both sides of the mobile vehicle body 101, an internal drive shaft 115 rotatably mounted inside the mobile vehicle body 101, an internal gear 116 and an external drive wheel 117 fixedly mounted on the internal drive shaft 115, a walking track 119 wrapped around the external drive wheel 117 and the external drive wheel 118, a walking motor 113 fixedly mounted inside the mobile vehicle body 101, a motor gear 114 fixedly mounted on the motor shaft of the walking motor 113, and the motor gear 114 meshing with the internal gear 116.

[0032] like Figure 4 , Figure 5 As shown, the main structure also includes two sponge blocks 105 fixedly installed on the lifting bracket 104, two electric cylinders 120 fixedly installed on the lifting bracket 104, and a counterweight block 102 fixedly installed on the moving vehicle body 101.

[0033] The walking motor 113 drives the motor gear 114 to rotate, which in turn drives the internal gear 116, the internal transmission shaft 115, and the outer drive wheel 117 to rotate. The outer drive wheel 117 then drives the walking track 119 to rotate, thus enabling the device to move. The mobile vehicle body 101 is also equipped with a steering mechanism to control the direction of movement. The lifting motor 106 drives the motor wheel 107 to rotate, which in turn drives the lower transmission wheel 109 to rotate via the lifting transmission belt 108. The lower transmission wheel 109 drives the vertical transmission belt 112 to rotate, which in turn drives the connecting plate 110 to rise and fall, thereby causing the lifting bracket 104 to rise and fall along the vertical support 103. The device first moves to the power panel cabinet 4 to be transferred. First, the support arm 201 and the positioning arm 202 are inserted into the power panel cabinet. Below the power cabinet 4, the power cabinet 4 is positioned on the supporting roller 203. Then, the lifting bracket 104 rises, lifting the power cabinet 4 from the ground. The device then moves the power cabinet 4 to the fixed channel steel 5 to be installed. Then, the moving vehicle 101 moves between the two fixed channel steels 5. Then, the moving vehicle 101 moves the power cabinet 4 to the installation position. Then, the lifting bracket 104 descends, placing the power cabinet 4 on the fixed channel steel 5. The mounting holes of the power cabinet 4 fall onto the anchor bolts on the fixed channel steel 5. If it is necessary to install two power cabinets 4 tightly, the newly installed power cabinet 4 is placed next to the already installed power cabinet 4, and then the electric cylinder 120 is extended to make the two power cabinets 4 fit tightly before fixing the newly installed power cabinet 4.

[0034] like Figure 6 , Figure 7 As shown, the adjustment mechanism also includes an internal adjustment screw 208 rotatably mounted on the lifting bracket 104. The internal adjustment screw 208 has two threads in opposite directions. An internal adjustment gear 209 is fixedly mounted on the internal adjustment screw 208. The internal adjustment screw 208 and the support arm 201 form a threaded transmission. A central gear 207 is rotatably mounted inside the moving body 101. The central gear 207 meshes with the internal adjustment gear 209. An adjustment motor 205 is fixedly mounted inside the moving body 101. An adjustment gear 206 is fixedly mounted on the motor shaft of the adjustment motor 205. The adjustment gear 206 meshes with the central gear 207.

[0035] For example Figure 6 , Figure 7 As shown, the adjustment mechanism also includes two positioning arms 202 slidably mounted on the lifting bracket 104. Multiple supporting rollers 203 are rotatably mounted on the positioning arms 202. A positioning rod 204 is fixedly mounted on the outside of the positioning arms 202. An external adjusting screw 210 is rotatably mounted inside the lifting bracket 104. The external adjusting screw 210 is provided with two sections of threads in opposite directions. An external adjusting gear 211 is fixedly mounted on the external adjusting screw 210. The external adjusting gear 211 meshes with the internal adjusting gear 209. The positioning arms 202 and the external adjusting screw 210 form a threaded transmission.

[0036] The adjusting motor 205 drives the adjusting gear 206 to rotate, which in turn drives the intermediate gear 207 to rotate. The intermediate gear 207 drives the inner adjusting gear 209 and the inner adjusting screw 208 to rotate. The inner adjusting gear 209 drives the outer adjusting gear 211 and the outer adjusting screw 210 to rotate. The inner adjusting screw 208 drives the two support arms 201 to slide inward or outward simultaneously. The outer adjusting screw 210 rotates and drives the two positioning arms 202 to slide inward or outward simultaneously. First, the device moves between the two fixed channel steels 5, causing the two positioning arms 202 and the support arms 201 to move outward. When both positioning rods 204 are in contact with the fixed channel steels 5, the positioning arms 202 and the support arms 201 are in the appropriate position, thereby realizing the adjustment of the position of the positioning arms 202 and the support arms 201 according to the fixed channel steels 5 and the power cabinet 4 of different sizes.

[0037] like Figures 8-10 As shown, the leveling mechanism includes multiple support motors 301 fixedly mounted on the support arm 201. Each support arm 201 has two mating gears 310 and two intermediate wheels 302 rotatably mounted on it. The support motors 301 drive the intermediate wheels 302 to rotate through the front transmission belt 303, and the intermediate wheels 302 drive the mating gears 310 to rotate through the rear transmission belt 304.

[0038] like Figures 8-10 As shown, the leveling mechanism also includes an opening at the end of the support arm 201, in which a support leg module is placed. The support leg module includes an inner rotating cylinder 305, which is placed in the opening at the end of the support arm 201. An upper top plate 306 and an external gear 307 are fixedly installed on the inner rotating cylinder 305. The external gear 307 meshes with the mating gear 310. An inner screw 308 is rotatably installed inside the inner rotating cylinder 305. A leveling foot 309 is fixedly installed below the inner screw 308. The inner screw 308 and the inner rotating cylinder 305 form a threaded transmission.

[0039] After the lifting bracket 104 descends and places the power panel cabinet 4 on the fixed channel steel 5, the leveling feet 309 contact the ground. At this time, the support motor 301 drives the intermediate wheel 302 to rotate via the front transmission belt 303. The intermediate wheel 302 drives the docking gear 310 to rotate via the rear transmission belt 304. The docking gear 310 drives the external gear 307 and the inner rotating drum 305 to rotate. Since the leveling feet 309 are now in contact with the ground, the inner rotating drum 305 rotates. Through the threaded transmission between the inner rotating drum 305 and the inner screw 308, the inner rotating drum 305 rotates. The device rises, thus placing the upper plate 306 under the power cabinet 4. After the upper plate 306 contacts the lower surface of the power cabinet 4, the upper plate 306 continues to rise, which will drive the power cabinet 4 to rise. The four corners of the bottom of the power cabinet 4 are leveled by the four support modules. After the four corners of the power cabinet 4 are leveled, the power cabinet 4 is manually fixed to the anchor bolts on the fixing channel steel 5. Then the device leaves the power cabinet 4, the support arm 201 and the positioning arm 202 are pulled out from under the power cabinet 4, and the support module is separated from the support arm 201 and remains under the power cabinet 4.

[0040] The working principle of the power grid power cabinet installation and transfer device disclosed in this invention is as follows: the walking motor 113 drives the motor gear 114 to rotate, the motor gear 114 drives the internal gear 116, the internal transmission shaft 115 and the outer drive wheel 117 to rotate, and the outer drive wheel 117 drives the walking track 119 to rotate, realizing the movement of the device. The mobile vehicle body 101 is also equipped with a steering mechanism to control the direction of movement. The adjusting motor 205 drives the adjusting gear 206 to rotate, the adjusting gear 206 drives the intermediate gear 207 to rotate, the intermediate gear 207 drives the internal adjusting gear 209 and the internal adjusting screw 208 to rotate, and the internal adjusting gear... Wheel 209 drives external adjusting gear 211 and external adjusting screw 210 to rotate. Internal adjusting screw 208 drives two supporting arms 201 to slide inward or outward simultaneously. External adjusting screw 210 rotates and drives two positioning arms 202 to slide inward or outward simultaneously. First, the device moves between two fixed channel steels 5, causing the two positioning arms 202 and supporting arms 201 to move outward. When both positioning rods 204 are in contact with the fixed channel steels 5, the positioning arms 202 and supporting arms 201 are in the appropriate position, thereby realizing the adjustment of the position of positioning arms 202 and supporting arms 201 according to the fixed channel steels 5 and power cabinets 4 of different sizes.

[0041] The lifting motor 106 drives the motor wheel 107 to rotate. The motor wheel 107 drives the lower drive wheel 109 to rotate via the lifting transmission belt 108. The lower drive wheel 109 drives the vertical transmission belt 112 to rotate. The vertical transmission belt 112 drives the connecting plate 110 to rise and fall, thereby driving the lifting bracket 104 to rise and fall along the vertical support 103. The device first moves to the power panel cabinet 4 to be transferred. First, the support arm 201 and the positioning arm 202 are inserted under the power panel cabinet 4. The power panel cabinet 4 is located on the supporting roller 203. Then, the lifting bracket 104 rises, lifting the power panel cabinet 4 from the ground. Then the device carries... The power panel cabinet 4 moves to the fixed channel steel 5 to be installed. Then, the moving vehicle 101 moves between the two fixed channel steels 5. The moving vehicle 101 then moves the power panel cabinet 4 to the installation position. Then, the lifting bracket 104 descends and places the power panel cabinet 4 on the fixed channel steel 5. The mounting holes of the power panel cabinet 4 fall into the anchor bolts on the fixed channel steel 5. If it is necessary to install two power panel cabinets 4 tightly, the newly installed power panel cabinet 4 is placed next to the already installed power panel cabinet 4 and then pressed against the extension of the electric cylinder 120 so that the two power panel cabinets 4 are pressed tightly together before fixing the newly installed power panel cabinet 4.

[0042] After the lifting bracket 104 descends and places the power panel cabinet 4 on the fixed channel steel 5, the leveling feet 309 contact the ground. At this time, the support motor 301 drives the intermediate wheel 302 to rotate via the front transmission belt 303. The intermediate wheel 302 drives the docking gear 310 to rotate via the rear transmission belt 304. The docking gear 310 drives the external gear 307 and the inner rotating drum 305 to rotate. Since the leveling feet 309 are now in contact with the ground, the inner rotating drum 305 rotates. Through the threaded transmission between the inner rotating drum 305 and the inner screw 308, the inner rotating drum 305 rotates. The device rises, thus placing the upper plate 306 under the power cabinet 4. After the upper plate 306 contacts the lower surface of the power cabinet 4, the upper plate 306 continues to rise, which will drive the power cabinet 4 to rise. The four corners of the bottom of the power cabinet 4 are leveled by the four support modules. After the four corners of the power cabinet 4 are leveled, the power cabinet 4 is manually fixed to the anchor bolts on the fixing channel steel 5. Then the device leaves the power cabinet 4, the support arm 201 and the positioning arm 202 are pulled out from under the power cabinet 4, and the support module is separated from the support arm 201 and remains under the power cabinet 4.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
