Description

Technical Field

[0001] This invention relates to the field of power distribution equipment transportation technology, specifically to an electrical cabinet transfer device. Background Technology

[0002] With the continuous development of the power industry, the demand for the transfer of heavy electrical equipment such as distribution cabinets and control and protection cabinets at construction and maintenance sites is becoming increasingly frequent. These cabinets are mostly sheet metal cabinets, integrating precision electrical components. They are usually large in size and heavy in weight. Traditional manual handling methods are not only time-consuming and labor-intensive, but also prone to damaging the equipment. Therefore, the industry generally uses mechanized handling equipment to assist in lifting and moving operations.

[0003] Existing methods for transporting cabinets mainly include using ordinary hydraulic forklifts, sling-assisted lifting, and simple clamping fixtures. Ordinary hydraulic forklifts require pre-drilled fork holes at the bottom of the cabinet; if these holes are missing, the cabinet must first be moved onto the forklift's forklift teeth, and this method can easily damage the cables and components at the bottom of the cabinet. Sling-assisted handling is cumbersome, results in uneven force distribution, and is prone to cabinet slippage and tilting during transport, posing risks of collisions and personnel safety. Existing simple clamping fixtures mostly involve rigid contact, which can easily scratch the cabinet's paint and cause deformation.

[0004] Chinese Patent CN220867035U discloses a power distribution cabinet transport device for easy lifting of a power distribution cabinet. This device includes a U-shaped base frame with wheels installed at each of the four bottom corners. Limiting posts are fixedly installed at each of the four top corners of the U-shaped base frame. A single U-shaped top frame is fixedly installed at the top of each of the four limiting posts. A single U-shaped movable frame is slidably fitted onto each of the four limiting posts. A lifting assembly is installed on the U-shaped movable frame, and a threaded assembly is connected to its rear inner wall. Clamping assemblies are installed on the left and right sides of the U-shaped top frame. Each clamping assembly includes a limiting rod, a connecting rod, and a clamping plate. The limiting rod slides through one side of the inner wall of the U-shaped top frame. The clamping plate is fixedly installed at the end of the limiting rod located inside the U-shaped top frame. The connecting rod is inclined, with its top end rotatably connected to the bottom of the limiting rod and its bottom end rotatably connected to the top of the U-shaped movable frame. During operation, the screw in the threaded assembly is rotated to move the U-shaped moving frame upward. The lifting assembly lifts the distribution cabinet off the ground. As the U-shaped moving frame moves upward, the two limit rods are pushed by the two connecting rods to bring the two limit rods closer to each other until the distribution cabinet is clamped by the two clamps with anti-slip pads fixed on one side. Then, the distribution cabinet can be moved by pushing the U-shaped top frame.

[0005] The aforementioned distribution cabinet transport equipment utilizes a linkage transmission to simultaneously lift and clamp the distribution cabinet. However, in practical applications, the clamping state of this equipment is directly determined by the final position of the U-shaped moving frame via the inclined linkage. Once the U-shaped moving frame stops rising and locks its height, the thrust of the linkage no longer changes, and the lateral position of the limit rod and the clamping plate is completely fixed. At this point, the clamping plate relies solely on the static friction provided by the anti-slip pads to maintain its suspended clamping state. In actual transport operations, the road surfaces at substations or construction sites are often uneven. When the transport equipment is pushed, moved, started or stopped urgently, or crosses small obstacles, it inevitably generates severe vibrations and inertial impacts. Because the distribution cabinet itself is extremely heavy, when subjected to the combined impact of vertical downward gravity and bumps and vibrations, it is very easy to exceed the maximum static friction limit provided by the anti-slip pads of the plywood. During transportation, it is easy to slip and fall, which will not only cause expensive cabinet deformation, large-area peeling of paint and damage to internal precision electrical components, but may also threaten the personal safety of on-site handling personnel. Summary of the Invention

[0006] The purpose of this invention is to provide an electrical cabinet transfer device to solve the technical problem that existing electrical cabinet transfer devices are prone to causing electrical cabinets to fall during the transfer process.

[0007] To solve the above problems, the present invention provides a technical solution for an electrical cabinet transfer device:

[0008] An electrical cabinet transfer device includes two clamping parts that can be raised and lowered in the vertical direction. The two clamping parts are arranged opposite each other and the distance between them in the horizontal direction is adjustable. Each clamping part includes at least one set of clamping components, and the clamping components include clamping seats and clamping members. The clamping member slides and is anti-disengaged with the clamping seat, and the sliding contact surface between the clamping member and the clamping seat is an inclined mating surface that gradually slopes from top to bottom. The inclined mating surface guides the clamping member to generate a horizontal clamping displacement that moves towards another clamping part when the clamping member slides downward relative to the clamping seat.

[0009] The beneficial effects of this invention are as follows: The electrical cabinet transfer device of this invention adopts a clamping assembly consisting of a clamping seat, a clamping member, and an elastic reset member. The inclined mating surface between the clamping member and the clamping seat can convert the downward sliding force of the electrical cabinet into a horizontal clamping force, achieving an anti-slip self-locking effect. When the electrical cabinet tends to slide downwards due to bumps, starting and stopping, or crossing obstacles during the transfer process, it will use the initial surface friction to drive the clamping member to move downwards synchronously. At this time, the inclined mating surface will forcefully convert the downward displacement of the clamping member into a horizontal displacement that presses the electrical cabinet inwards. This causes the horizontal clamping force on the electrical cabinet to automatically increase with its downward trend, achieving a self-locking effect where the clamping becomes tighter as it slides down. This avoids the dangerous hazard of the electrical cabinet falling due to the instantaneous breakthrough of static friction in traditional rigid clamping.

[0010] Furthermore, one of the clamps and clamping members is provided with an anti-detachment clamping arm, and the other is provided with an anti-detachment groove that slides with and cooperates with the anti-detachment clamping arm to prevent detachment. The extension direction of the anti-detachment clamping arm is the same as the extension direction of the inclined mating surface.

[0011] Beneficial effects: The cooperative structure of the anti-detachment arm and the anti-detachment groove can accurately guide the sliding direction of the clamping component, ensuring that the clamping component always moves along the extension direction of the inclined mating surface, and avoiding the clamping component from deviating or getting stuck; in addition, during the sliding of the clamping component, the anti-detachment arm will not come out in the anti-detachment groove, ensuring the clamping stability of the clamping component.

[0012] Furthermore, the clamping assembly also includes an elastic reset member connected between the clamping seat and the clamping member, which provides an upward sliding reset preload force for the clamping member.

[0013] Beneficial effects: The elastic reset component can automatically reset the clamping component after the clamping action is released, without the need for manual intervention, thus improving the transfer efficiency.

[0014] Furthermore, the clamping part includes at least two sets of the clamping components.

[0015] Beneficial effects: It can increase the number of contact points with the electrical cabinet, disperse the clamping force, and avoid local deformation of the electrical cabinet caused by excessive force at a single point; the combined action of multiple clamping components can improve the overall stability of the clamping and reduce the occurrence of shaking and tilting of the electrical cabinet.

[0016] Furthermore, the clamping components in the clamping part are arranged in at least two rows at intervals in the vertical direction.

[0017] Beneficial effects: It can clamp electrical cabinets at different heights, increasing the vertical clamping range and improving the clamping stability of taller electrical cabinets, preventing the electrical cabinets from tipping over during transportation; at the same time, the multi-row arrangement of clamping components can further disperse the clamping force, better protecting the sheet metal structure and internal precision components of the electrical cabinet.

[0018] Furthermore, the clamping part includes a mounting base plate. In each row of clamping components, at least one set of clamping components is fixedly connected to the mounting base plate, and at least one set of clamping components slides with the mounting base plate to achieve adjustment of the horizontal spacing between the clamping components on the same side.

[0019] Beneficial effects: This invention enables flexible adaptation to electrical cabinets of different depths, while avoiding structures and components that cannot be clamped on the sides of the electrical cabinet. It can complete the transfer operation of electrical cabinets of different specifications without changing tooling, thus improving the versatility and flexibility of the transfer equipment.

[0020] Furthermore, the mounting base plate is an L-shaped plate, including a long side clamping plate segment and a short side limiting plate segment. All clamping components are mounted on the long side clamping plate segment, and the short side limiting plate segment is used to limit the electrical cabinet.

[0021] Beneficial effects: The L-shaped mounting base plate can install clamping components through the long side clamping plate segment, which can provide sufficient arrangement space for multiple clamping components, and facilitate the installation and position adjustment of the clamping components; the short side limiting plate segment can form a limiting cooperation with the electrical cabinet when clamping the electrical cabinet, restricting the front and rear displacement of the electrical cabinet during the transfer process, further improving the stability of the transfer, and preventing the electrical cabinet from slipping off the clamping part.

[0022] Furthermore, the surface of the clamping member used to clamp the electrical cabinet is provided with a flexible padding layer.

[0023] Beneficial effects: The flexible padding layer can achieve flexible contact with the surface of the electrical cabinet, avoiding scratches on the paint surface of the electrical cabinet caused by rigid clamping; the flexible padding layer can also buffer vibration and impact during transportation, prevent the sheet metal structure of the electrical cabinet from being squeezed and deformed, and protect the precision electrical components inside the cabinet from damage.

[0024] Furthermore, it also includes a hydraulic forklift lifting frame, which is equipped with a synchronous drive mechanism. The synchronous drive mechanism is in transmission cooperation with two clamping parts to drive the two clamping parts to move synchronously towards each other or synchronously away from each other.

[0025] Beneficial effects: The hydraulic forklift lifting frame has a strong load-bearing capacity and stable and reliable lifting, which can meet the lifting and transportation needs of heavy electrical cabinets. It has its own mobility function and does not require an additional walking mechanism. The clamping distance can be adjusted by using a set of synchronous drive mechanisms, which can achieve uniform clamping and reduce the number of drive mechanisms required.

[0026] Furthermore, the synchronous drive mechanism is a bidirectional lead screw drive mechanism, including a bidirectional lead screw, two transmission nuts, and a power input component; the power input component is an operating handwheel or a drive motor, the bidirectional lead screw is rotatably assembled with the hydraulic forklift lifting frame, the bidirectional lead screw has two threaded transmission sections with opposite thread directions, and the two transmission nuts are respectively threadedly connected to the two threaded transmission sections; the two clamping parts are respectively connected to the two transmission nuts, and the mounting base plate is slidably engaged with the hydraulic forklift lifting frame.

[0027] Beneficial effects: The bidirectional screw drive mechanism offers high transmission precision and smooth operation, accurately controlling the opening and closing distance of the two clamping parts, and is adaptable to electrical cabinets of different widths. The screw drive has a self-locking characteristic, automatically locking the clamping distance after clamping, preventing the clamping parts from opening during transport and improving clamping reliability. When the power input is a handwheel, the structure is simple, requiring only one person to operate, and no power supply is needed, making it suitable for use on construction sites without external power. When the drive motor is used as the power input, electric adjustment is possible, reducing the labor intensity of operators. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Embodiments of the electrical cabinet transfer device of the present invention: like Figure 1 and Figure 2 As shown, the electrical cabinet transfer equipment includes a hydraulic forklift lifting frame 1, a synchronous drive mechanism 9, a left clamping part 3, and a right clamping part 4.

[0032] The hydraulic forklift lifting frame 1 serves as the basic load-bearing and moving mechanism of the entire electrical cabinet transfer equipment. It can meet the transfer requirements of heavy electrical cabinets and drive the left clamping part 3, the right clamping part 4, and the clamped electrical cabinet to complete vertical lifting operations and horizontal transfer operations.

[0033] In this embodiment, the hydraulic forklift lifting frame 1 adopts a common manual hydraulic stacker mast structure in the prior art, and the whole includes a frame, lifting arm 2, hydraulic cylinder, drive rod and chain assembly. Figure 3 , Figure 4 and Figure 5 As shown, the left clamping part 3 and the right clamping part 4 are both installed on the lifting arm 2. By operating the drive rod, the hydraulic cylinder is controlled to extend and retract, and then the lifting arm 2 is driven to rise and fall through the chain assembly, thereby realizing the raising and lowering of the left clamping part 3 and the right clamping part 4.

[0034] like Figure 1 As shown, the synchronous drive mechanism 9 is installed on the lifting arm 2 of the hydraulic forklift lifting frame 1, and rises and falls synchronously with the lifting arm 2. It is also connected to the left clamping part 3 and the right clamping part 4 for transmission, driving the left clamping part 3 and the right clamping part 4 to move synchronously towards or away from each other, thereby adjusting the horizontal distance between the left clamping part 3 and the right clamping part 4. The left clamping part 3 and the right clamping part 4 are arranged opposite to each other. In this embodiment, the left clamping part 3 and the right clamping part 4 have the same structure; the following description uses the structure of the right clamping part 4 as an example.

[0035] like Figure 6As shown, the right clamping part 4 includes a mounting base plate 41 and two rows of clamping assemblies 42 arranged vertically. The clamping assemblies 42 are used to directly clamp the side of the electrical cabinet to fix it in place. The mounting base plate 41 is an L-shaped plate, including an integrally formed long-side clamping plate segment 411 and a short-side limiting plate segment 412. The long-side clamping plate segment 411 extends in the front-back direction, and the short-side limiting plate segment 412 extends in the left-right direction. Both rows of clamping assemblies 42 are installed on the inner surface of the long-side clamping plate segment 411. The short-side limiting plate segment 412 is used to fit against the front or rear surface of the electrical cabinet when clamping it, forming a limiting fit to restrict the front-back displacement of the electrical cabinet during transportation and prevent the electrical cabinet from slipping off from the front-back direction of the two clamping parts.

[0036] The long-side clamping plate segment 411 is provided with two first slide rails 5 arranged vertically and horizontally at intervals, the first slide rails 5 extending in the front-to-back direction. For example... Figure 1 As shown, each row of clamping components 42 includes two sets of clamping components 42. One set of clamping components 42 slides with the first slide rail 5 via the first slider 7, while the other set of clamping components 42 is fixed to the long side clamping plate segment 411, thereby achieving adjustment of the horizontal spacing between the clamping components 42 on the same side. By adjusting the spacing of the clamping components 42 on the same side, electrical cabinets of different depths can be flexibly adapted, while avoiding structures and devices that cannot be clamped on the side of the electrical cabinet. The transfer operation of electrical cabinets of different specifications can be completed without changing the tooling, improving the versatility and flexibility of the equipment.

[0037] In this embodiment, as Figure 7 and Figure 8 As shown, the clamping assembly 42 includes a clamping base 421, a clamping member 422, and an elastic reset member 423. The clamping member 422 slides and is anti-disengaged with the clamping base 421. The surfaces of the clamping base 421 and the clamping member 422 opposite each other are provided with inclined mating surfaces 424 that gradually slope downwards towards the other clamping part. The inclination angle of the inclined mating surfaces 424 is set according to actual needs to ensure good force conversion effect and self-locking performance. When the clamping member 422 slides downwards relative to the clamping base 421, the inclined mating surfaces 424 guide the clamping member 422 to generate a horizontal clamping displacement that moves towards the other clamping part, thereby increasing the clamping force on the electrical cabinet.

[0038] like Figure 7 and Figure 9As shown, the clamping base 421 is provided with a sliding engagement groove extending in the same direction as the inclined engagement surface 424. The tops of the two groove walls of the sliding engagement groove extend inwards to form flanges parallel to the inclined engagement surface 424, forming anti-detachment clamping arms 4211. The clamping member 422 slides in the sliding engagement groove, and anti-detachment sliding grooves 4221 are respectively provided on the front and rear sides of the clamping member 422 to slide and prevent detachment from the two anti-detachment clamping arms 4211. The length of the anti-detachment sliding grooves 4221 matches the maximum sliding stroke of the clamping member 422. The clamping member 422 will not detach from the clamping base 421 during its sliding relative to the clamping base 421.

[0039] An elastic reset element 423 is connected between the clamping base 421 and the clamping element 422, providing a pre-tightening force for the clamping element 422 to slide upwards. The elastic reset element 423 is a tension spring, with its upper end fixedly connected to the top of the clamping base 421 and its lower end fixedly connected to the bottom of the clamping element 422. When the electrical cabinet is not clamped, the tension of the tension spring pulls the clamping element 422 upwards, keeping it in its initial position for easy clamping in the next operation. When the electrical cabinet is clamped, the weight of the cabinet and the downward sliding force overcome the tension of the tension spring, causing the clamping element 422 to slide downwards, resulting in a horizontal clamping displacement. After the clamping is released, the tension of the tension spring causes the clamping element 422 to automatically slide upwards and reset, eliminating the need for manual intervention and improving the efficiency of the transfer operation.

[0040] The clamping member 422 has a flexible pad 4222 fixedly installed on the surface of the electrical cabinet for clamping. The flexible pad 4222 is made of a non-metallic material with good elasticity and wear resistance. In actual use, a rubber pad can be used to form flexible contact with the surface of the electrical cabinet. The flexible pad 4222 can prevent rigid clamping from scratching the paint surface of the electrical cabinet, and at the same time, it can buffer the vibration and impact generated during transportation, prevent the sheet metal structure of the electrical cabinet from being squeezed and deformed, and protect the precision electrical components inside the cabinet from damage.

[0041] In this embodiment, the synchronous drive mechanism 9 adopts a bidirectional lead screw drive mechanism, including a bidirectional lead screw 92, a first transmission nut 93, a second transmission nut 94, and a power input component. The bidirectional lead screw 92 extends in the left-right direction, and its two ends are rotatably assembled with the lifting arm 2 through bearings, allowing the bidirectional lead screw 92 to rotate freely around its own axis. The bidirectional lead screw 92 is provided with two threaded transmission sections with opposite thread directions, and the first transmission nut 93 and the second transmission nut 94 are respectively threadedly connected to the two threaded transmission sections. The first transmission nut 93 is connected to the mounting base plate 41 of the right clamping part 4, and the second transmission nut 94 is connected to the mounting base plate 41 of the left clamping part 3.

[0042] To ensure smooth movement of the left clamping part 3 and the right clamping part 4, two second slide rails 6 are provided on the lifting arm 2, spaced vertically, extending in the left-right direction. Second sliders 8 are connected to the mounting base plates 41 of the left clamping part 3 and the right clamping part 4 at positions corresponding to the second slide rails 6, and the second sliders 8 slide in contact with the second slide rails 6. A power input component is fixedly connected to one end of the bidirectional lead screw 92 to drive its rotation. In this embodiment, the power input component is an operating handwheel 91, which is a circular disc with anti-slip textures on its surface for easy manual rotation by the operator. Of course, in other embodiments, the power input component can also be a drive motor, with its output shaft connected to one end of the bidirectional lead screw 92 via a coupling, enabling electric drive and reducing the operator's workload. When the bidirectional lead screw 92 rotates, the first transmission nut 93 and the second transmission nut 94 move synchronously in opposite directions along the axis of the bidirectional lead screw 92 under the action of the threaded drive. This causes the left clamping part 3 and the right clamping part 4 to clamp towards each other or open away from each other synchronously, thus adapting to electrical cabinets of different widths. The threaded drive itself has a self-locking characteristic, which can automatically lock the distance between the left clamping part 3 and the right clamping part 4 after clamping in place, preventing the two clamping parts from opening on their own during transportation and ensuring the reliability of clamping.

[0043] The working process of the electrical cabinet transfer device of the present invention is as follows: First, the operator rotates the power input component, based on the width of the electrical cabinet to be transferred, to drive the bidirectional lead screw 92 to rotate, causing the left clamping part 3 and the right clamping part 4 to move synchronously in opposite directions, adjusting the distance between the two clamping parts to be slightly larger than the width of the electrical cabinet. Then, based on the depth and side structure of the electrical cabinet, the horizontal distance between the sliding clamping components 42 on the left and right clamping parts 3 and 4 on the same side is adjusted, ensuring that the clamping components 42 can avoid protruding structures and unclampable parts on the side of the electrical cabinet, while ensuring effective contact between the clamping components 42 and the side of the electrical cabinet. Next, the drive lever of the hydraulic forklift lifting frame 1 is operated to control the lifting arm 2 to descend, matching the height of the clamping parts with the clamping height of the electrical cabinet. Then, the power input component is rotated in the opposite direction, causing the left clamping part 3 and the right clamping part 4 to move synchronously in opposite directions until the flexible padding layer 4222 on the surface of the clamping component 422 is tightly attached to both sides of the electrical cabinet, completing the pre-clamping of the electrical cabinet. Subsequently, the drive lever of the hydraulic forklift lifting frame 1 is operated to control the lifting arm 2 to rise, thereby lifting the two clamping parts and the electrical cabinet off the ground.

[0044] During the lifting process, the weight of the electrical cabinet acts on the clamping member 422, causing it to slide downwards relative to the clamping seat 421. Under the action of the inclined mating surface 424 between the clamping seat 421 and the clamping member 422, the downward sliding displacement of the clamping member 422 is converted into a horizontal displacement that presses the electrical cabinet inwards, automatically increasing the clamping force and creating a self-locking effect. After the electrical cabinet is lifted to a suitable height, the operator pushes the hydraulic forklift lifting frame 1 to transfer the electrical cabinet to the designated position. During the transfer, if encountering road bumps, emergency starts / stops, or crossing obstacles, the electrical cabinet may tend to slide downwards. At this time, the friction between the electrical cabinet and the clamping member 422 will further drive the clamping member 422 downwards, further increasing the clamping force and effectively preventing the electrical cabinet from slipping and falling. After reaching the designated position, the operator operates the drive lever of the hydraulic forklift lifting frame 1 to control the lowering arm 2, placing the electrical cabinet on the ground. Then, the power input component is rotated, causing the left clamping part 3 and the right clamping part 4 to move synchronously in opposite directions, releasing the clamping of the electrical cabinet. At this time, the pulling force of the elastic reset component 423 will cause the clamping part 422 to automatically slide upward and reset to the initial position, preparing for the next transfer operation.

[0045] In the above embodiments, the clamping base 421 is provided with an anti-detachment clamping arm 4211, and the clamping member 422 is provided with an anti-detachment and anti-detachment sliding groove 4221 that slides with the anti-detachment clamping arm 4211; in other embodiments, the anti-detachment clamping arm 4211 may also be provided on the clamping member 422, and a corresponding anti-detachment and anti-detachment sliding groove 4221 may be provided on the clamping base 421.

[0046] In the above embodiments, the elastic reset member 423 is a tension spring, with its upper end fixedly connected to the top of the clamping seat 421 and its lower end fixedly connected to the bottom of the clamping member 422. In other embodiments, the elastic reset member 423 can also be a compression spring, vertically disposed between the bottom of the clamping seat 421 and the bottom of the clamping member 422, providing an upward reset preload force to the clamping member 422 through the spring force; the elastic reset member 423 can also be a gas spring, with its two ends hinged to the clamping seat 421 and the clamping member 422 respectively, which can also achieve automatic reset of the clamping member 422. Of course, in other embodiments, the elastic reset member 423 may not be provided, and manual reset may be used.

[0047] In the above embodiments, the flexible pad 4222 is made of rubber; in other embodiments, the flexible pad 4222 can also be made of polyurethane, which has better wear resistance and cushioning performance, and can further improve the protection effect on the surface of the electrical cabinet; the flexible pad 4222 can also be made of silicone, which is suitable for electrical cabinet transfer scenarios with higher surface protection requirements.

[0048] In the above embodiments, each clamping part includes two rows of clamping components 42, and each row is provided with two sets of clamping components 42; in other embodiments, depending on the transfer requirements of the electrical cabinet, each clamping part may also be provided with only one row, or with three or more rows of clamping components 42.

[0049] In the above embodiments, the hydraulic forklift lift 1 adopts a manual hydraulic stacker mast structure; in other embodiments, the hydraulic forklift lift 1 can also adopt an electro-hydraulic stacker mast structure, where a motor drives a hydraulic oil pump to supply oil to the hydraulic cylinder, realizing the automatic lifting and lowering of the lifting arm 2 without the need for manual pressing of the drive lever, thus reducing the labor intensity of the operator. In the description of this specification, "a plurality of" means at least two, such as two, three or more, unless otherwise explicitly specified.

[0050] While various embodiments of the invention have been shown and described in this specification, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the invention.
