Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a lifting device for installing power equipment. Background Technology

[0002] There are many types of electrical equipment, such as distribution transformers and low-voltage distribution cabinets, which have a certain weight and volume. For example, distribution transformers and other such equipment usually need to be installed at a certain height. It is difficult to move and install them to the designated location by manpower alone, so lifting equipment is required.

[0003] Lifting equipment has a wide range of applications in industrial production and special operations. Existing lifting equipment used for power equipment installation, while possessing certain lifting functions, is insufficient in terms of mobility and cannot meet the transportation needs of power equipment. Furthermore, after reaching the installation location, it is inconvenient to adjust the angle to face the unloading port towards the installation side, thus causing considerable inconvenience. In addition, since both the lifting equipment and the power equipment to be installed have a large volume and weight, it is necessary to ensure safety during the construction process. Therefore, we propose a lifting equipment for power equipment installation. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome the shortcomings of existing technologies and provide a lifting device for installing electrical equipment. This device can conveniently pull the equipment and the electrical device to be installed to a safe area and has reliable lifting components, effectively saving the physical exertion of installation personnel. The movable wheel support at the bottom turns in place after reaching the installation position to face the unloading port towards the installation position of the external frame. In addition, when moving the electrical equipment, the movable ramp is pressed down and overlaps with the external installation frame, allowing the electrical equipment to gradually slide towards the installation position of the external frame under the push of the pusher, thus greatly improving the convenience of the electrical equipment transfer process. It also has a reliable support and clamping unit, which can effectively ensure the stability of the equipment and the lifted electrical device during the lifting process, preventing the equipment from tipping over or slipping, thereby effectively ensuring the safety during operation and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for installing power equipment, comprising a base plate, a lifting and pushing unit, and a support and clamping unit;

[0006] The base plate has chamfered corners at its four corners, and each chamfered surface has an inwardly facing mounting groove. The four mounting grooves are in an X-shaped structure. A movable wheel is installed in the middle of the lower left side of the base plate, and two one-way wheels are installed on the lower right side of the base plate.

[0007] The lifting and pushing unit includes a mounting frame, a ball screw, an H-nut, a support frame, a shelf, a hydraulic cylinder, and a movable wheel. Four vertical mounting frames are fixedly connected to the upper end of the base plate. The mounting frames are inverted U-shaped structures, and the four mounting frames are arranged diagonally in a rectangle. Each mounting frame contains a set of ball screws, which include a vertical screw rod, an H-nut, and a drive motor embedded inside the base plate. The H-nut is horizontally positioned, and its two ends engage with the two side members of the U-shaped mounting frame. A support frame is fixedly connected to the vertical surface of the H-nut on its inward-facing side. The support frame is formed by two blocks, a horizontal square and a vertical triangle, vertically fixed together. The shelf is fixed to the upper side of the support frame via bolts on the lower side. A hydraulic cylinder is embedded at the center of the lower end of the base plate. The telescopic end of the hydraulic cylinder faces vertically downwards and is rotatably connected to a movable wheel at its end.

[0008] Support clamping unit: installed on the front and rear sides of the shelf and at the four corners of the base plate.

[0009] The mounting bracket is used for installing the ball screw. When the ball screw is running, it can lift and lower the shelf via the H-nut, thereby raising the electrical equipment placed on the shelf. The H-nut structure allows for a limiting engagement between the nut and the mounting bracket, ensuring smooth sliding of the nut. The triangular block on the underside of the support bracket increases the connection area with the H-nut, improving the stability of the H-nut installation and enhancing the load-bearing capacity of the support bracket. The hydraulic cylinder pushes the movable wheel to the ground, providing the main support for the entire equipment. The movable wheel and the hydraulic cylinder's telescopic rod can rotate relative to each other, allowing the entire device to rotate around the movable wheel to adjust the direction of the equipment's movement.

[0010] Furthermore, the lifting and pushing unit also includes a connecting block, a movable locking block, a telescopic sleeve, and a handle. A connecting block is fixedly connected to the middle position on the left side of the base plate. The movable locking block has a U-shaped structure and is rotatably connected to the connecting block via a shaft. One end of the telescopic sleeve is fixedly connected to the end of the movable locking block away from the shaft, and the other end of the telescopic sleeve has a circular structure with a handle fixedly connected inside, with both ends of the handle extending outwards. When the movable wheel and support legs are both lower than the wheels, the device can move. The telescopic sleeve can be pulled out using the handle to increase the overall length of the pull rod assembly. The movable locking block is movably connected to the connecting block, allowing the telescopic sleeve to be adjusted in vertical angle to accommodate users of different heights. The two extended handles allow two workers to pull the device simultaneously. The wheel structure at the bottom allows the device to move easily and conveniently, carrying electrical equipment to the installation area. The movable wheel near the direction of travel supports the overall steering of the device.

[0011] Furthermore, the lifting and pushing unit also includes a mounting base one, a hydraulic cylinder two, a pusher, a movable platform, and a torsion spring. An L-shaped mounting base one is fixedly connected to the middle of the left side of the shelf. The horizontal section of the mounting base one is fixedly connected to the bottom of the shelf. The vertical section of the mounting base one is close to the left end of the shelf, and a hydraulic cylinder two is embedded inside the vertical section. The telescopic end of the hydraulic cylinder two extends horizontally to the right, and an X-shaped pusher is fixedly connected to the end. The right side of the shelf has two notches, front and rear, and a rod is fixedly connected inside the notches. One end of the movable platform is a U-shaped structure, and this U-shaped end is rotatably connected to the rod inside the notch on the right side of the shelf. A torsion spring is sleeved on the outside of the rod, and the two torsion arms of the torsion spring are fixedly connected to the shelf and the movable platform, respectively. Mounting base one is used for the installation of hydraulic cylinder two. Hydraulic cylinder two pushes the items on the shelf to the edge of the shelf. Under normal conditions, the torsion spring lifts the two movable ramps to a vertical position, which protects the electrical equipment. When the electrical equipment is moved, the movable ramps will gradually be pressed down to a horizontal position as the electrical equipment moves. The movable ramps overlap with the external mounting frame, so that the electrical equipment can gradually slide to the installation position of the external frame under the push of the pusher, which greatly improves the convenience of the electrical equipment transfer process.

[0012] Furthermore, the support and clamping unit includes a mounting slide, a locking block, a third hydraulic cylinder, a fourth hydraulic cylinder, and a support foot. An L-shaped mounting slide is slidably connected inside the mounting groove. Locking blocks are fixedly connected to the left and right sides of the mounting slide. Locking slots are provided on the left and right inner walls of the mounting groove. The locking blocks are inserted into and slidably connected in the locking slots. A third hydraulic cylinder is embedded in the horizontal section of the mounting slide. The end of the telescopic rod of the third hydraulic cylinder is fixedly connected to the innermost inner wall of the mounting groove. A fourth hydraulic cylinder is embedded in the vertical section of the mounting slide. The telescopic end of the fourth hydraulic cylinder extends downwards and is fixedly connected to a circular support foot at its end. The mounting slide is used for mounting the hydraulic cylinder and the outriggers. The hydraulic cylinder pushes the outriggers down, so that the outriggers at the four corners are all in contact with the ground. This allows it to provide auxiliary support to the base plate at the four corners, centered around the movable wheel, effectively improving the stability of the equipment, preventing accidental tipping, and ensuring safety during the lifting process. Under the action of the hydraulic cylinder, the mounting slide can move horizontally to adjust the grounding position of the four outriggers. This allows the extension distance of the four outriggers to be adjusted according to the size of the equipment being lifted. The locking block is used to vertically limit the mounting slide, allowing it to slide along the mounting groove.

[0013] Furthermore, the support and clamping unit also includes mounting base two, hydraulic cylinder five, and clamping plates. Mounting base two is fixedly connected to the middle position of the front and rear sides of the placement plate. The upper end of mounting base two is higher than the placement plate, and a hydraulic cylinder five is embedded on each opposite side of the two mounting base two. The end of the extension rod of the hydraulic cylinder five is fixedly connected to the clamping plate. Mounting base two is used for mounting hydraulic cylinder five. The hydraulic cylinder five on the front and rear sides pushes the two clamping plates closer together, thereby clamping and fixing the electrical equipment placed on the placement plate to ensure the stability of the electrical equipment during the lifting process.

[0014] Furthermore, it also includes a controller. The controller is embedded in the front side of the base plate, and a control switch is installed on the upper side of the cylindrical structure at the end of the telescopic sleeve. The controller is used to control the synchronous start and stop of the drive motors of hydraulic cylinders three and four and ball screws at various positions. The control switch at the cylindrical structure at the end of the telescopic sleeve allows the operator to easily control the start and stop of the operation of each electrical device when pulling or rotating the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This embodiment provides a technical solution: a lifting device for installing power equipment, including a base plate 1, a lifting and pushing unit 3 and a support and clamping unit 4;

The mounting slide 41 is used for mounting the hydraulic cylinder 44 and the support legs 45. The hydraulic cylinder 44 pushes the support legs 45 downward, so that the support legs 45 at the four corners are all in contact with the ground. This allows it to provide auxiliary support for the base plate 1 at the four corners around the movable wheel 37, effectively improving the stability of the equipment, preventing accidental tipping, and ensuring safety during the lifting process. Under the action of the hydraulic cylinder 43, the mounting slide 41 can move horizontally to adjust the grounding position of the four support legs 45.
