Description

Technical Field

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

[0002] Most electrical equipment is large and heavy. During installation, due to safety considerations, it is usually necessary to install it at a height. When installing large electrical equipment at a height, lifting devices are required.

[0003] The existing equipment has the following drawbacks: When removing the power equipment from the lifting device, it is generally necessary to use the guide rollers on the lifting device to push the power equipment off the lifting device and then push it onto the placement platform to be installed. However, when pushing the lifting device onto the placement platform, the heavy power equipment will cause uneven force on the lifting device. When the power equipment moves to the end of the lifting device, the eccentric force on the lifting device is the greatest, so there is a risk of tilting the lifting device, which poses certain safety hazards when installing the power equipment.

[0004] Therefore, this application proposes a lifting device for installing power equipment to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a lifting device for installing power equipment, in order to solve the problem that the lifting device is subjected to uneven force when the power equipment is heavy, and the lifting device is subjected to the greatest eccentric force when the power equipment is moved to the end of the lifting device, so the lifting device is at risk of tilting.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for installing power equipment, comprising a main frame and a placement unit adjustablely disposed on one side of the main frame to support the power equipment, and further comprising:

[0007] A lifting unit, mounted on the main frame and connected to the placement unit, is used to adjust the installation height of the placement unit;

[0008] An adjustment unit, disposed on the lifting unit, is used to push the electrical equipment out of the placement unit;

[0009] A support unit is disposed below the placement unit and connected to the adjustment unit, which supports the placement unit and the placement platform of the power equipment when the power equipment is pushed out.

[0010] The lifting unit includes a hydraulic cylinder mounted on the main frame, a placement frame mounted on the power output end of the hydraulic cylinder, a limiting block mounted on the side of the placement frame near the main frame, a roller mounted on the limiting block and slidably connected to the main frame, and a lifting plate mounted on the lower end of the placement frame. The main frame has a limiting groove at the position corresponding to the roller for the roller to move.

[0011] The adjustment unit includes a fixed base fixedly mounted on the placement frame, a rack mounted on the upper end of the fixed base, a guide rod fixedly mounted on the fixed base, a guide block slidably mounted on the guide rod, a movable frame fixedly mounted on the guide block, a motor mounted on the upper end of the movable frame, and a gear mounted on the power output end of the motor. The gear is threadedly connected to the rack. The lower end of the movable frame is provided with a fixed plate for supporting the power equipment, and an electromagnet is provided on the fixed plate.

[0012] The support unit includes a traction rope disposed at the lower end of the movable frame, a mounting plate disposed at the lower end of the lifting plate, a movable plate disposed on the side of the traction rope away from the movable frame, a movable rod disposed on the side of the movable plate close to the mounting plate, and a support device disposed on the side of the movable rod away from the movable plate to support the power equipment mounting platform. The traction rope passes through the lifting plate, and the lifting plate has a threading hole at the position corresponding to the traction rope for the traction rope to move. The movable rod passes through the mounting plate, and an elastic element is sleeved between the support device and the mounting plate on the movable rod.

[0013] The supporting device includes a push plate disposed on the moving rod and a side plate disposed on the side of the push plate away from the moving rod. A slider is disposed on the side plate near the lifting plate. The slider is slidably disposed in the middle of the lifting plate. The lifting plate has a groove for the slider to move at the position corresponding to the slider.

[0014] The side plate has a mounting groove in the middle, and a wedge-shaped support plate is placed inside the mounting groove. A positioning rod is provided on the support plate near the side plate. The positioning rod is rotatably connected to the side plate. The side plate has a positioning hole for placing the positioning rod at the position corresponding to the positioning rod.

[0015] The push plate is provided with a support block at a position below the support plate to support the support plate.

[0016] The placement unit includes a fixed frame fixedly disposed on the upper end of the lifting plate, a limiting plate disposed on the side of the fixed frame near the placement frame, and a mounting frame disposed on the inner side of the fixed frame and fixedly connected to the lifting plate. Guide rollers are provided at intervals on the mounting frame.

[0017] The main frame is fixedly mounted at the lower end of the main frame below the lifting plate, and a base is mounted on the side of the main frame away from the lifting plate. Both the base and the fixed frame are equipped with wheels.

[0018] The base has a counterweight at its upper end and a handle on the side of the base away from the main frame. The handle has a control button that is electrically connected to the hydraulic cylinder.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention places the power equipment to be lifted onto the placement unit, then moves the entire device to the location where the power equipment needs to be installed. The lifting unit is activated, causing the placement unit to move upwards on the main frame. Once the placement unit is level with the mounting platform of the power equipment, it is brought into contact with the platform. Then, the adjusting unit is activated to push the power equipment on the upper part of the placement unit towards one side of the platform. During this pushing process, the adjusting unit also moves the support unit towards one side of the platform. The support unit is fixed to both the placement unit and the support platform, preventing the placement unit from tipping over due to eccentric forces when the power equipment moves towards the platform, thus preventing the power equipment from slipping off the placement unit and causing damage. This improves the safety performance during the lifting and installation of power equipment. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-15 The present invention provides a technical solution: a lifting device for installing power equipment, comprising a main frame 1 and a placement unit 3 adjustablely disposed on one side of the main frame 1 for supporting the power equipment, and further comprising:

[0039] Lifting unit 2 is mounted on the main frame 1 and connected to placement unit 3, and is used to adjust the installation height of placement unit 3;

[0040] Adjustment unit 4, mounted on lifting unit 2, is used to push the power equipment out of placement unit 3;

[0041] The support unit 5 is located below the placement unit 3 and connected to the adjustment unit 4, and supports the placement unit 3 and the placement platform of the power equipment when the power equipment is pushed out.

[0042] It should be noted that during operation, the electrical equipment to be lifted is placed on the placement unit 3, and then the entire device is moved to the location where the electrical equipment needs to be installed. The lifting unit 2 is activated to move the placement unit 3 upward on the main frame 1. When the placement unit 3 is raised to be flush with the installation platform of the electrical equipment, the placement unit 3 is brought into contact with the platform. Then, the adjusting unit 4 is activated to push the electrical equipment on the upper end of the placement unit 3 towards one side of the platform. During the pushing process, the adjusting unit 4 moves the support unit 5 towards one side of the platform. The support unit 5 is fixed to the placement unit 3 and the support platform to provide support. This can prevent the placement unit 3 from tipping over due to eccentric force when the electrical equipment moves towards one side of the platform, which could cause the electrical equipment to slip off the placement unit 3 and be damaged. This improves the safety performance when lifting and installing electrical equipment.

[0043] In one embodiment, the lifting unit 2 includes a hydraulic cylinder 21 mounted on the main frame 1, a placement frame 22 mounted on the power output end of the hydraulic cylinder 21, a limiting block 23 mounted on the side of the placement frame 22 close to the main frame 1, a roller 24 mounted on the limiting block 23 and slidably connected to the main frame 1, and a lifting plate 25 mounted on the lower end of the placement frame 22. A limiting groove 101 for the roller 24 to move is provided at the position of the roller 24 on the main frame 1.

[0044] With this design, starting the hydraulic cylinder 21 drives the placement frame 22 to move upward, causing the roller 24 at the upper end of the limiting block 23 to move inside the limiting groove 101. The limiting groove 101 can restrict the movement position of the roller 24, making the up-and-down movement of the placement frame 22 more stable, thereby improving the stability and safety when transporting electrical equipment at high altitudes.

[0045] In one embodiment, the adjustment unit 4 includes a fixed base 41 fixedly mounted on the placement frame 22, a rack 42 fixedly mounted on the upper end of the fixed base 41, a guide rod 43 fixedly mounted on the fixed base 41, a guide block 47 slidably mounted on the guide rod 43, a movable frame 46 fixedly mounted on the guide block 47, a motor 44 fixedly mounted on the upper end of the movable frame 46, and a gear 45 fixedly mounted on the power output end of the motor 44. The gear 45 is threadedly connected to the rack 42. A fixed plate 48 for supporting the power equipment is fixedly mounted on the lower end of the movable frame 46, and an electromagnet 49 is fixedly mounted on the fixed plate 48.

[0046] This design pushes the electrical equipment closer to the fixed plate 48. After the electrical equipment contacts the fixed plate 48, the electromagnet 49 is activated, making the fixed plate 48 magnetic. The fixed plate 48 and the electrical equipment are magnetically fixed, which allows the electrical equipment to be fixed by the fixed plate 48 during high-altitude transportation, improving the stability of the electrical equipment installation. When the electrical equipment is lifted to the designated installation height, the motor 44 is activated, causing the gear 45 to mesh with the rack 42, driving the guide block 47 to move on the guide rod 43. This causes the moving frame 46 to move the fixed plate 48 above the lifting plate 25. The fixed plate 48 pushes the electrical equipment above the placement unit 3 towards one side of the placement platform. Then, the electromagnet 49 is de-energized, stopping the magnetic fixation of the electrical equipment by the fixed plate 48. The electrical equipment is then pushed out of the placement unit 3 and moved to the placement platform.

[0047] In one embodiment, reference Figures 7-9 The support unit 5 includes a traction rope 51 disposed at the lower end of the movable frame 46, a mounting plate 54 disposed at the lower end of the lifting plate 25, a movable plate 52 disposed on the side of the traction rope 51 away from the movable frame 46, a movable rod 53 disposed on the side of the movable plate 52 close to the mounting plate 54, and a support device 55 disposed on the side of the movable rod 53 away from the movable plate 52 to support the power equipment mounting platform. The traction rope 51 passes through the lifting plate 25, and the lifting plate 25 has a wire hole 252 for the traction rope 51 to move at the position corresponding to the traction rope 51. The movable rod 53 passes through the mounting plate 54, and an elastic element 56 is sleeved between the support device 55 and the mounting plate 54. The elastic element 56 is made of a spring or an elastic pad.

[0048] With this design, when the moving frame 46 is in its original position, the traction rope 51 stretches the support device 55, and the support device 55 compresses the elastic element 56. The elastic element 56 is compressed between the support device 55 and the mounting plate 54. When the moving frame 46 drives the fixing plate 48 to push the power equipment out of the placement unit 3, the traction rope 51 moves to one side of the placement unit 3, and the tension of the traction rope 51 on the support device 55 gradually decreases. Then, under the action of the elastic element 56, the support device 55 moves to one side of the placement platform and supports the upper end of the placement platform. This can support and fix the lifting plate 25 and the placement platform, and prevent the lifting plate 25 from tipping over and causing the power equipment to detach from the placement unit 3 when the power equipment is moved from the placement unit 3 to the placement platform.

[0049] In one embodiment, the support device 55 includes a push plate 551 disposed on the moving rod 53 and a side plate 552 disposed on the side of the push plate 551 away from the moving rod 53. A slider 555 is disposed on the side plate 552 near the lifting plate 25. The slider 555 is slidably disposed in the middle of the lifting plate 25. A groove 251 for the slider 555 to move is provided at the position of the corresponding slider 555 on the lifting plate 25.

[0050] With this design, the moving rod 53 pushes the push plate 551 to one side of the placement platform, so that the side plate 552 extends from the lower part of the lifting plate 25 and then supports the upper end of the placement platform, connecting the lifting plate 25 to the placement platform. This prevents the pressure on the placement unit 3 from shifting when the power equipment moves on the placement unit 3, causing uneven force on the placement unit 3 and causing the entire lifting device to tip over.

[0051] In one embodiment, a mounting groove 5522 is provided in the middle of the side plate 552. A wedge-shaped support plate 554 is placed inside the mounting groove 5522. A positioning rod 5541 is provided at a position of the support plate 554 close to the side plate 552. The positioning rod 5541 is rotatably connected in the side plate 552. A positioning hole 5521 for placing the positioning rod 5541 is provided at the position of the positioning rod 5541 in the side plate 552.

[0052] With this design, when the side plate 552 moves closer to the placement platform, the support plate 554 contacts the placement platform, causing the support plate 554 to rotate along the positioning rod 5541. Then, the upper end of the support plate 554 is tilted, which makes it easier for the power equipment to slide off the placement unit 3 and facilitates the unloading of the power equipment.

[0053] In one embodiment, a support block 553 is provided at a position below the corresponding support plate 554 of the push plate 551 to support the support plate 554.

[0054] With this design, the support block 553 can support the support plate 554, so that when the side plate 552 is stored inside the lifting plate 25, the support plate 554 is placed on the upper end of the support block 553.

[0055] In one embodiment, the placement unit 3 includes a fixed frame 31 fixedly disposed on the upper end of the lifting plate 25, a limiting plate 32 disposed on the side of the fixed frame 31 near the placement frame 22, and a mounting frame 33 disposed inside the fixed frame 31 and fixedly connected to the lifting plate 25. Guide rollers 34 are spaced apart on the mounting frame 33.

[0056] This design allows the power equipment to be moved to the upper end of the mounting frame 33, where it contacts the guide roller 34, facilitating its movement on the mounting frame 33. The limiting plate 32 restricts the movement of the power equipment on the mounting frame 33. When the power equipment contacts the limiting plate 32, the upper part of the power equipment is fixed to the fixing plate 48.

[0057] In one embodiment, a fixing frame 14 is fixedly installed at the lower end of the main frame 1 below the lifting plate 25, and a base 11 is provided on the side of the main frame 1 away from the lifting plate 25. Both the base 11 and the fixing frame 14 are provided with wheels 15.

[0058] With this design, the wheels 15 can easily move the entire lifting equipment, thus facilitating the transportation of electrical equipment.

[0059] In one embodiment, a counterweight 12 is provided at the upper end of the base 11, and a handle 13 is provided on the side of the base 11 away from the main frame 1. A control button 131 electrically connected to the hydraulic cylinder 21 is provided on the handle 13.

[0060] With this design, the counterweight 12 can prevent the entire device from tilting due to uneven force when the power equipment is placed on the mounting frame 33. The handle 13 makes it easy for the staff to move the entire device. The control button 131 is used to control the opening and vertical movement of the hydraulic cylinder 21, thereby facilitating the control of the installation height of the power equipment.
