Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a distribution cabinet transfer device. Background Technology

[0002] Distribution cabinets are electrical equipment that are small in size, easy to install, have flexible and fixed locations, are not easily restricted by site conditions, and are widely used. They have advantages such as stable and reliable operation, high space utilization, small footprint, and environmental benefits. Currently, distribution cabinets used on construction sites are mostly mounted on brackets, and their positions often need to be moved as the project progresses, resulting in tedious and heavy work involving the disassembly, installation, and relocation of these cabinets from their fixed brackets. Utility Model Content

[0003] The purpose of this utility model is to provide a power distribution cabinet transfer device, which can simplify the disassembly and installation process during the transfer of power distribution cabinets, and has the characteristics of flexible transfer operation, which helps to improve the efficiency of power distribution cabinet transfer operation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a power distribution cabinet transfer device.

[0005] It includes a frame on which the power distribution cabinet is fixedly installed, a pair of support seats arranged opposite each other on the frame, and a screw drive unit that corresponds to and matches the support seats.

[0006] The frame consists of a base plate and a top plate that is fixedly supported above the base plate. A caster wheel assembly and a directional wheel assembly are located at the bottom of the base plate. The distribution cabinet is fixed to the top plate.

[0007] The support body is located between the base plate and the top plate, and has two pairs of opposing upright plates, with the pairs of upright plates arranged side by side. A through hole is formed on the base plate for the upright plates to pass through downwards. A vertically extending outer arm is formed on the lower part of each upright plate.

[0008] The screw drive unit is mounted on the frame and can be matched with two support seats. It can drive the support seats to move up and down relative to the base plate, so that the lower end face of the outer vertical arm can approach and move away from the ground.

[0009] Optionally, the directional wheel assembly includes two directional wheels arranged opposite each other in front and behind, and the two directional wheels are located near the two left corners of the base plate to form the front and rear supports on the left side of the frame; the swivel wheel assembly includes two swivel wheels arranged opposite each other in front and behind, and the two swivel wheels are located near the two right corners of the base plate to form the front and rear supports on the right side of the frame.

[0010] Optionally, a connecting plate is provided between two opposite outer uprights, extending to the left or right in the lateral direction. The connecting plate has slotted structures formed at least alternately front and rear.

[0011] Optionally, the lower part of the upright plate on the support base on the same side as the directional wheel assembly is formed with an inner upright arm, and the inner upright arm on the same side is closer to the directional wheel than the outer upright arm. The downward extension length of the inner upright arm is less than the downward extension length of the outer upright arm. The left and right distance between the inner upright arms on the paired upright plates is consistent with the outer diameter of the directional wheel. When the support base moves up and down relative to the base plate, the inner wall surface of the inner upright arm can be selectively switched between a state of contact with the circumferential surface of the directional wheel and a state of disengagement.

[0012] Optionally, an elastic band is fixedly provided on the lower part of the opposite end face of the inner vertical arm. When the inner vertical arm contacts the circumferential surface of the directional wheel, the elastic band can undergo elastic deformation.

[0013] Optionally, the screw drive unit includes a hand crank fixed at one end of the screw body that extends above the top plate.

[0014] Optionally, a chain drive unit is also included. The chain drive unit includes sprockets on the screw bodies of the screw drive units forming the left and right sides, respectively, and a chain disposed between the two sprockets. A hand crank can be provided on the screw body of the screw drive unit that matches the support seat on the left side, and the hand crank is fixed at the end of the screw body extending above the top plate. Manually rotating the hand crank causes the screw body on the left and right sides to rotate synchronously, thereby causing the support seats on both sides to move up and down synchronously.

[0015] The beneficial effects of this utility model are: it can simplify the disassembly and installation process during the transfer of distribution cabinets, and also has the convenient operation characteristics of flexible transfer of distribution cabinets, which helps to improve the efficiency of distribution cabinet transfer operations and reduce labor intensity.

[0021] like Figures 1 to 3 The illustrated distribution cabinet transfer device includes a frame 20 on which a distribution cabinet 10 is fixedly mounted, a pair of support seats 30 arranged opposite each other on the frame 20, and screw drive units 40 that correspond one-to-one with the support seats 30. The screw body of the screw drive unit 40 is arranged axially in the vertical direction.

[0022] The frame 20 includes a base plate 21 and a top plate 22 fixedly supported above the base plate 21. Therefore, a vertical distance is formed between the base plate 21 and the top plate 22, which provides space for assembling the support base 30, screw drive unit 40, etc.

[0023] A caster wheel assembly 23 and a directional wheel assembly 24, arranged opposite each other, are provided on the lower part of the base plate 21. The caster wheel assembly 23 is installed on the right side of the base plate 21, and the directional wheel assembly 24 is installed on the left side of the base plate 21. To ensure the balance and stability of the frame 20 during movement, the directional wheel assembly 24 includes two directional wheels arranged opposite each other, generally located near the two left corners of the base plate 21, forming the front and rear supports on the left side of the frame 20. The caster wheel assembly 23 includes two casters arranged opposite each other, generally located near the two right corners of the base plate 21, forming the front and rear supports on the right side of the frame 20. The power distribution cabinet 10 is fixed to the top plate 22.

[0024] The main body of the support base 30 is located between the base plate 21 and the top plate 22, and each support base 30 is provided with two pairs of upright plates 31 facing each other, with the pairs of upright plates 31 arranged facing each other left and right. In other words, on the main body of the support base 30 on the left side (which can be understood as the horizontal plate 32 shown in the figure, the same below), there are two pairs of upright plates 31 on its front and rear sides, and the pair of upright plates 31 on the front and rear sides are arranged facing each other left and right; at the same time, on the main body of the support base 30 on the right side, there are also two pairs of upright plates 31 on its front and rear sides, and the pair of upright plates 31 on the front and rear sides are also arranged facing each other left and right. The left-right (vertical) distance between the pairs of upright plates 31 (opposite faces) is greater than the outer diameter of the omnidirectional wheel and the outer diameter of the directional wheel, so that the pairs of upright plates 31 can be distributed on the left and right sides of the omnidirectional wheel and the left and right sides of the directional wheel. See Figure 1 , Figure 2 As shown.

[0025] A through hole (shaped hole structure) is formed on the base plate 21 for the upright plate 31 to pass through downwards. The through hole forms a channel for the upright plate 31 to extend downwards relative to the base plate 21, and a slide structure is formed to constrain the upward and downward movement of the upright plate 31 relative to the base plate 21. Vertically downward extending outer upright arms 311 are formed on the lower part of each upright plate 31. The lateral (vertical) distance between the two outer upright arms 311 (opposite faces) on a pair of upright plates 31 is greater than the lateral (vertical) distance between the two upright plates 31 in the pair. An elastic pad 3111 is fixedly provided on the lower end face of each outer upright arm 311, and the thickness of the elastic pad 3111 is generally between 5mm and 15mm.

[0026] The screw drive unit 40 is mounted on the frame 20 and can be matched with two support seats 30 respectively. Manually or electrically driving the screw of the screw drive unit 40 to rotate around the vertical axis causes the support seat 30 to move up and down relative to the base plate 21, allowing the lower end face of the outer vertical arm 311 to move closer to or further away from the ground / mounting platform. Driving the support seat 30 to move upward relative to the frame 20, causing the lower end face of the outer vertical arm 311 to detach from the ground / mounting platform, switches the distribution cabinet transfer device to transfer cart mode; conversely, driving the support seat 30 to move downward relative to the frame 20, causing the lower end face of the outer vertical arm 311 to contact the ground / mounting platform, switches the distribution cabinet transfer device to support frame mode.

[0027] The upper and lower ends of the screw body in the screw drive unit 40 are respectively fixed on the base plate 21 and the top plate 22. (See also...) Figure 2 As shown, a protrusion 211 is formed on the lower end surface of the base plate 21, so that the lower end of the screw body extends into the shaft cavity provided on the protrusion 211.

[0028] like Figure 1 , Figure 2 As shown, a connecting plate 3112 is provided between the two opposing outer upright arms 311. The connecting plate 3112 connects the two opposing outer upright arms 311 into a whole, increasing the rigidity of the outer upright arms 311 and the contact area with the ground / mounting platform, thereby improving the support stability (in the form of a support frame). The connecting plate 3112 extends horizontally to the left or right, that is, towards the side opposite to the opposing surface between the two opposing outer upright arms 311. The connecting plate 3112 has alternating slotted holes, allowing it to be fixed to the ground or mounting platform using screws, anchor rods / rivets, or bolts. Therefore, the connecting plate 3112 increases the stability of the entire distribution cabinet transfer device.

[0029] On the support base 30 (i.e., the support base 30 on the left side in the figure), which is on the same side as the directional wheel assembly 24, the lower part of each of the upright plates 31 has an inner upright arm 312, and the inner upright arms 312 on the same side (left and right) are closer to the directional wheel than the outer upright arms 311. The downward extension length of the inner upright arm 312 is less than the downward extension length of the outer upright arm 311. The left-right (vertical) distance between the inner upright arms 312 (opposite faces) on the paired upright plates 31 is consistent with the outer diameter of the directional wheel. Therefore, when the support base 30 moves up and down relative to the base plate 21, the inner wall surface (lower part) of the inner upright arm 312 can be selectively switched between a contact state and a disengaged state with the circumferential surface of the directional wheel. An elastic band 3121 is fixedly provided on the lower part of the opposite end face between the inner upright arms 312. When the inner support arm 312 contacts the circumferential surface of the directional wheel, the elastic band 3121 undergoes elastic deformation, keeping the directional wheel in a state where it cannot rotate or roll. The thickness of the elastic band 3121 is controlled to be more than 5mm, and the end face of the elastic band 3121 protrudes outward relative to the inner end face of the inner support arm 312. This allows the end face of the elastic band 3121 to form a protruding arc surface, which facilitates tangential contact between the end face of the elastic band 3121 and the circumferential surface of the directional wheel. Ultimately, this causes the directional wheel surface to sink into the body of the elastic band 3121, thereby significantly increasing the contact friction resistance between the elastic band 3121 and the circumferential surface of the directional wheel.

[0030] The screw drive unit 40 located on the left side includes a handwheel 41 fixedly mounted at one end of the screw body extending above the top plate 22. Manually rotating the handwheel 41 causes the screw body in the left screw drive unit 40 to rotate around its vertical axis. A chain drive unit 50 is disposed between the left and right screw drive units 40. The chain drive unit 50 includes two sprockets and a chain formed on the screw bodies of the screw drive units 40 on both sides. The chain meshes with the two sprockets. When the screw body on the left side is turned, power is transmitted to the screw body on the right side through the matching of the sprockets and the chain, causing it to rotate synchronously. This achieves the purpose of driving the support seats 30 on both sides to move synchronously up and down relative to the base plate 21 / frame 20.

[0031] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Many aspects of this utility model can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
