Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet processing technology, specifically to a support-type power distribution cabinet assembly and transfer vehicle. Background Technology

[0002] During the installation of the distribution cabinet, channel steel feet (such as those for mounting the cabinet) need to be installed at the bottom of the cabinet. Figure 1 (As shown) to ensure the long-term safe and stable operation of equipment. The main functions of the channel steel anchor include providing a stable and rigid foundation, locking the cabinet to the anchored channel steel on the ground with bolts to form a whole, enhancing the cabinet's resistance to vibration and preventing displacement and overturning, effectively raising the cabinet to isolate it from the ground, preventing moisture corrosion and accidental water immersion, protecting internal precision electrical components, providing a platform for precise leveling and overall alignment during on-site installation, and facilitating cable introduction and laying as well as subsequent maintenance work. Therefore, the channel steel anchor is a reliable structural design to ensure the protection, safety, installability, and maintainability of power distribution equipment.

[0003] However, in the current production process of distribution cabinets, after the main cabinet is initially hoisted and placed on the ground, assembly work is usually carried out directly in the initial position. Installing the mounting feet requires manual labor or the use of overhead cranes to lift the heavy cabinet, which carries the risk of the cabinet swaying or even falling, creating safety hazards during the installation of the channel steel mounting feet. Furthermore, the bare cabinet without mounting feet has no support points at the bottom, resulting in significant resistance to movement and easy damage to the cabinet panels when placed directly on the ground, making it almost entirely reliant on overhead cranes for workstation changes. This forces multiple processes, such as welding and cabinet door installation, to be concentrated at the initial placement point, causing material accumulation, workstation congestion, and impacting production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a support-type distribution cabinet assembly and transfer vehicle that eliminates the operational risks of manually or by crane lifting the cabinet when installing the channel steel feet, enabling safe installation of the cabinet while it is suspended in the air. It also allows for flexible transfer of the cabinet, facilitates reasonable planning and circulation, avoids overcrowding at workstations, and effectively improves production efficiency.

[0005] Technical solution: A support-type distribution cabinet assembly and transfer vehicle includes a base frame and moving wheels located at the lower end of the base frame. Two support components are spaced apart on the base frame. Each support component includes a pair of oppositely arranged support structures located on opposite sides of the base frame. Each support structure includes at least one support unit that is detachably stacked. The upper ends of the two support structures of the same support component are provided with load-bearing beams that span the opposite sides of the base frame. The distance between the load-bearing beams of the two support components is smaller than the distance between the channel steel feet of the distribution cabinet. The combined height of the support structure and the load-bearing beams can be adjusted to be higher than the height of the channel steel feet.

[0006] A further improvement of this utility model is that a first sliding groove extending along its length is provided on the upper surface of the frame edge of the bottom frame, and the bottom support unit of the support structure is slidably connected to the first sliding groove through a first slider and can be selectively fixed at different positions on the first sliding groove.

[0007] A further improvement of this utility model is that the upper surface of the support unit is provided with a second sliding groove through the width direction of the bottom frame, and the bottom of the adjacent upper support unit is provided with a second slider that cooperates with the second sliding groove.

[0008] A further improvement of this utility model is that the first slide groove and the second slide groove are both T-shaped slide grooves, and the first slider and the second slider are both T-shaped sliders that cooperate with the T-shaped slide grooves.

[0009] A further improvement of this utility model is that the support unit is provided with vertically extending locking structures on both sides, and a locking member is provided between the locking structure and the first slide groove. The locking member acts on the locking structure and the mating structure in the first slide groove through fasteners to fix the support unit.

[0010] A further improvement of this utility model is that the locking structure is a T-shaped groove vertically arranged on both sides of the support unit, the mating structure is a T-shaped nut arranged in the T-shaped groove, the locking member is provided with a connecting hole, the fastener is a bolt, and the bolt passes through the connecting hole and is threadedly connected to the locking structure and the T-shaped nut in the first groove.

[0011] A further improvement of this utility model is that the locking component includes a horizontal plate that mates with the upper end face of the frame edge of the bottom frame and a vertical plate that mates with the side wall of the support unit. At least one reinforcing plate is provided between the horizontal plate and the vertical plate, and the connecting hole is provided on the horizontal plate and the vertical plate.

[0012] A further improvement of this utility model is that the height of the vertical plate is adapted to the height of the support structure, and it is provided with connection holes corresponding to each support unit.

[0013] A further improvement of this utility model is that a vertical support rod is threadedly connected to the bottom frame, and the bottom end of the vertical support rod is provided with a ground-supporting foot. Beneficial effects

[0014] This utility model uses a movable base frame and support components to allow the cabinet to be placed directly on the support components during initial placement, providing support for the lower end of the distribution cabinet. This eliminates the operational risks of manually or by crane lifting the cabinet when installing the channel steel feet, enabling safe installation while the cabinet is suspended in the air. Furthermore, the use of a transfer vehicle as an independent mobile unit allows the distribution cabinet to be moved flexibly regardless of whether feet are installed, facilitating rational planning and flow, avoiding overcrowding at workstations, and effectively improving production efficiency.

[0015] This utility model achieves flexible adjustment of the support height through detachable and stackable support units and adjustable-spacing load-bearing beams, allowing the distribution cabinet to be raised to the height required for installation on the channel steel feet. It adapts to the installation requirements of channel steel feet for distribution cabinets of different sizes, enhancing versatility.

[0016] This invention uses a locking structure with fasteners to rigidly fix the support unit to the bottom frame, and connects it to each layer of support unit through a vertical plate, thereby reducing the risk of swaying of the support unit under load and improving the overall structural stability.

Detailed Implementation

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: Combination Figures 1-3 It is known that a support-type distribution cabinet assembly and transfer vehicle includes a base frame 1 and a moving wheel 2 located at the lower end of the base frame 1. Two support components are spaced apart on the base frame 1. Each support component includes a pair of oppositely arranged support structures, which are located on opposite sides of the base frame. Each support structure includes at least one support unit 3 that is detachably stacked. The upper ends of the two support structures of the same support component are provided with load-bearing beams 4 that span the opposite sides of the base frame. The distance between the load-bearing beams 4 of the two support components is smaller than the distance between the channel steel feet of the distribution cabinet. The combined height of the support structure and the load-bearing beams 4 can be adjusted to be higher than the height of the channel steel feet.

[0023] The upper surface of the frame edge of the bottom frame 1 is provided with a first sliding groove 5 extending along its length direction. The bottom support unit 3 of the support structure is slidably connected to the first sliding groove 5 through the first slider 6 and can be selectively fixed at different positions on the first sliding groove 5.

[0024] A second groove 7 is provided through the upper surface of the support unit 3 along the width direction of the bottom frame 1, and a second slider 8 that cooperates with the second groove 7 is provided at the bottom of the adjacent upper support unit 3. The second slider 8 is fixedly connected to the bottom of the support unit 3. When multiple support units 3 are stacked, each upper support unit 3 is positioned and connected by embedding its bottom second slider 8 into the second groove 7 on the upper surface of the lower support unit 3.

[0025] Preferably, the support unit 3 is a rectangular block structure made of steel, with a height of 100mm to 200mm. Support units of different heights can be selected and combined as needed.

[0026] Preferably, both the first slide rail 5 and the second slide rail 7 are T-shaped slide rails, and both the first slider 6 and the second slider 8 are T-shaped sliders that cooperate with the T-shaped slide rails. The cooperation structure between the T-shaped slide rails and the sliders provides high load-bearing strength, prevents the support unit 3 from dislodging under heavy loads, and ensures the stability and safety of the cabinet placement process.

[0027] The load-bearing beam 4 is preferably made of steel. Both ends of the load-bearing beam 4 are fixedly connected to the upper surface of the uppermost support unit 3 of the corresponding support structure by bolts or other fasteners. Preferably, countersunk holes are formed at the top of both ends of the load-bearing beam 4 (corresponding to the positions of the lower support structure). Bolts are installed in the countersunk holes. Nuts that mate with these bolts are pre-placed in the second groove 7 at the top of the uppermost support unit 3 of the support structure. During installation, the load-bearing beam 4 is placed on top of the uppermost support unit 3, and its position is adjusted so that the countersunk holes align with the lower second groove 7. Then, the bolts are inserted through the countersunk holes above the load-bearing beam 4, passed downwards through the countersunk holes, and screwed into the nuts located in the second groove 7. Tightening the bolts securely locks the load-bearing beam 4 onto the uppermost support unit 3 of the support structure.

[0028] Preferably, the upper surface of the supporting beam 4 is fixedly covered with an elastic layer. The elastic layer can be made of rubber, polyurethane, or other non-metallic wear-resistant materials with appropriate elastic modulus and coefficient of friction, and is firmly bonded to the upper surface of the supporting beam 4 by adhesive bonding or wrapping. The elastic layer effectively prevents the hard supporting beam 4 from directly contacting the bottom plate of the distribution cabinet, playing a buffering and isolation role during support and movement, reducing the risk of scratches or bumps to the lower surface of the distribution cabinet, protecting the integrity of the cabinet shell, and increasing the friction between the elastic layer and the bottom of the distribution cabinet. This allows the operator to directly push the distribution cabinet body without having to push the trolley separately when the entire device needs to be moved. At this time, the sufficient friction generated between the elastic layer and the bottom of the cabinet can drive the transfer trolley below to move synchronously, improving the convenience and efficiency of the transfer operation.

[0029] The support unit 3 is provided with vertically extending locking structures 9 on both sides. A locking member is provided between the locking structure 9 and the first slide groove 5. The locking member acts on the locking structure and the mating structure in the first slide groove 5 through fasteners to fix the support unit 3.

[0030] The locking structure 9 is a T-shaped groove vertically arranged on both sides of the support unit 3. The mating structure is a nut set in the T-shaped groove. The locking component has a connecting hole, and the fastener is a bolt. The bolt passes through the connecting hole and is threadedly connected to the locking structure and the nut in the first groove 5. Preferably, the nut is a T-shaped nut 10.

[0031] Preferably, the locking component includes a horizontal plate 11 that mates with the upper end face of the frame edge of the bottom frame 1 and a vertical plate 12 that mates with the side wall of the support unit 3. At least one reinforcing plate 13 is provided between the horizontal plate 11 and the vertical plate 12, and connecting holes are provided on the horizontal plate 11 and the vertical plate 12.

[0032] The height of the vertical plate 12 is adapted to the height of the support structure, and it is provided with connection holes corresponding to each support unit 3. At least one connection hole is provided on the vertical plate 12 at the corresponding position on the side wall of each support unit 3. When a bolt passes through a connection hole on the vertical plate 12 and is screwed into the T-nut 10 in the locking structure 9 (T-groove) on the side wall of the support unit 3 at the corresponding height, the support unit 3 at that layer can be securely connected to the locking member. One locking member can simultaneously and firmly lock multiple layers of support units 3 and the bottom support unit 3 to the base frame 1, enhancing the overall strength of the support structure.

[0033] Since the total height of the support structure is adjusted by increasing or decreasing the number of support unit 3 layers (e.g., 1 layer, 2 layers, 3 layers, etc.), the locking member comes in various height specifications to ensure that the vertical plate 12 of the locking member can cover and effectively connect all layers of support unit 3. For each specification of locking member, the height of its vertical plate 12 and the position of its connecting holes correspond to the corresponding number of support structure layers. During operation, the corresponding specification of locking member is selected for installation based on the actual number of layers of the assembled support structure.

[0034] The casters 2 are four omnidirectional casters with brake mechanisms, installed at the four corners of the bottom of the base frame 1. Vertical support rods 14 are threaded onto the base frame 1, and the bottom ends of the vertical support rods 14 are provided with ground-holding feet 15. Preferably, at least one mounting plate is horizontally provided on one side of the base frame 1, and the vertical support rods are threaded onto the mounting plate. There are two or more vertical support rods 14, symmetrically distributed on both sides of the base frame 1. The ground-holding feet 15 are rubber pads or metal pads used to increase friction with the ground and provide stable support.

[0035] The working principle of the support-type power distribution cabinet assembly and transfer vehicle provided by this utility model is as follows: In use, first determine the required number of support units 3 and the installation position of the load-bearing beam 4 based on the dimensions of the distribution cabinet to be installed and the installation height requirements of the channel steel foot 16. Install the bottom support unit 3 in the first slide groove 5 of the bottom frame 1 via the first slider 6, and slide it along the first slide groove 5 to the predetermined position. If increased height is required, stack the upper support unit 3 on top of the bottom support unit 3, and position it using the cooperation of the second slider 8 and the second slide groove 7. After stacking the support units 3, install the load-bearing beam 4 on the top support unit 3. Then install the locking components, placing the horizontal plate 11 on the upper surface of the bottom frame 1, with the vertical plate 12 close to the side of the support unit 3. Use bolts to pass through the connecting holes on the horizontal plate 11 and the vertical plate 12, threading them into the T-nuts 10 in the T-shaped slide grooves on the sides of the support unit 3 and the T-nuts in the first slide groove 5 of the bottom frame 1, thus firmly fixing the entire support structure. Finally, the distribution cabinet is hoisted onto the supporting beam 4. The assembled transfer vehicle and distribution cabinet are then moved to the installation position using the transfer wheels 2. When fixed-point operation is required, the vertical support rod 14 is rotated to ensure that the ground anchor 15 is in close contact with the ground, providing additional support. When installing the channel steel anchor 16, operators can work without obstruction at the bottom of the distribution cabinet. After completion, the distribution cabinet and transfer vehicle are moved to the next work position.
