Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to an electrical installation and hoisting device. Background Technology

[0002] Electrical engineering is a series of installation projects related to power layout. During the electrical installation process, it is often necessary to lift some electrical equipment to a high place for installation, and hoisting equipment is required for hoisting.

[0003] Chinese Patent No. CN218642259U discloses an electrical installation hoisting device, including a hoisting box. A support frame is fixedly connected to the top of the hoisting box, and a fixed plate is fixedly connected to one side of the support frame. A limiting groove is formed on the top of the fixed plate, and a limiting rod is slidably connected inside the limiting groove. This electrical installation hoisting device includes a hoisting box, support frame, fixed plate, limiting groove, limiting rod, mounting plate, first motor, rotating rod, second motor, lead screw, moving plate, lead screw groove, sliding groove, and sliding rod. By starting the first motor, the fixed plate on the rotating rod rotates, allowing for angular rotation of the entire hoisting box and the electrical equipment. Simultaneously, starting the second motor rotates the lead screw, allowing the moving plate to move back and forth on the sliding rod via the sliding groove as needed. This facilitates the repositioning of the electrical equipment within the hoisting device, thus meeting the daily needs of electrical installation.

[0004] However, the above solution uses a self-locking screw to push the extrusion plate to extrude and limit the electrical equipment box, which cannot support the bottom of the electrical equipment. When the electrical equipment is transported at high altitudes, the resulting shaking can easily cause the electrical equipment to fall off, resulting in safety accidents and damage to the electrical equipment. Fixing the electrical equipment by extrusion can easily cause deformation of the electrical equipment shell, affecting the subsequent use of the electrical equipment. Utility Model Content

[0005] Existing electrical installation and hoisting equipment cannot support the bottom of electrical equipment, which can easily cause the equipment to fall off, resulting in safety accidents and damage. Fixing electrical equipment by squeezing can easily cause deformation of the equipment shell, affecting the subsequent use of the equipment. Therefore, this utility model proposes an electrical installation and hoisting device.

[0006] The present invention discloses an electrical installation hoisting device, including a limiting frame, wherein a clamping device is provided on the outer surface of the limiting frame, the clamping device including a clamping roller, and the clamping roller clamps the electrical equipment to be hoisted.

[0007] The limiting frame is equipped with a support device inside, which includes an outer support plate and an inner support plate. The outer support plate and the inner support plate support the electrical equipment that needs to be hoisted.

[0008] Preferably, the clamping device further includes a clamping screw, the two ends of which are rotatably connected to the outer surface of the limiting frame via bearings. A clamping motor is fixedly installed on the outer surface of the limiting frame. One end of the output shaft of the clamping motor is fixedly installed to one end of the clamping screw. A movable slider is threadedly connected to the outer surface of the clamping screw. The inner wall of the movable slider is slidably inserted into the outer surface of the limiting frame. One end of each of the clamping rollers is fixedly installed to the outer side of the limiting frame and the outer side of the movable slider, respectively.

[0009] The above technical solution involves using a clamping motor to drive the clamping screw to rotate, which in turn causes the moving slider to move left and right. This allows the clamping roller on the moving slider to move, making it easy to adjust according to the size of the electrical equipment. The outer surface of the clamping roller is fitted with a rubber sleeve to reduce damage to the electrical equipment.

[0010] Preferably, the outer surface of the limiting frame is hinged with an adjusting rod via a pin, one end of the adjusting rod is hinged to the upper surface of the movable slider via a pin, a connecting ring is fixedly installed at the hinge of the adjusting rod, a lifting rope passes through the lifting hole of the connecting ring, a lifting plate is fixedly installed on the outer surface of the lifting rope, and a lifting hook is fixedly installed on the outer surface of the lifting plate by bolts.

[0011] Through the above technical solution, the adjusting link can move with the moving slider, so that the adjusting link drives the connecting ring to always stay on the center plane of the electrical equipment, which facilitates the stability of the center. In order to fix the electrical equipment, the lifting ring on the electrical equipment is hung on the hook to fix the electrical equipment. The lifting rope can be connected to the lifting equipment, and the lifting plate and the lifting hook are fixed with bolts. The lifting hook can be changed according to the lifting ring of the electrical equipment.

[0012] Preferably, the support device further includes an adjusting screw, which is rotatably connected to the upper surface of the limiting frame via a bearing seat. A movable plate is threadedly connected to the outer surface of the adjusting screw, and the outer surface of the movable plate is slidably inserted into the inner wall of the limiting frame. A transmission bevel gear is rotatably connected to the outer surface of the limiting frame via a bearing, and the transmission bevel gear is slidably inserted into one end of the clamping screw.

[0013] Through the above technical solution, by adjusting the rotation of the lead screw, the moving plate can be moved, and the position of the transmission bevel gear can be adjusted. Thus, after the height of the supporting outer plate is adjusted, the meshing between the transmission bevel gear and the transmission rod bevel gear can be disengaged.

[0014] Preferably, the inner wall of the limiting frame is rotatably connected to a transmission rod with a bevel gear via a bearing, and the bevel gear of the transmission rod meshes with the transmission bevel gear.

[0015] The above technical solution enables the transmission bevel gear to drive the rotation of the transmission rod.

[0016] Preferably, a support screw with a bevel gear is rotatably connected to the inner wall of one side of the clamping roller via a bearing, and the bevel gear of the support screw meshes with the bevel gear of the transmission rod; a limit rod is fixedly installed on the inner wall of the other side of the clamping roller.

[0017] Through the above technical solution, the rotation of the transmission rod can drive the rotation of the support screw, thereby driving the support outer plate to rise and fall, which is convenient for adjustment according to the height of the electrical equipment.

[0018] Preferably, the outer surface of the support screw is threaded to one end of the outer support plate, the outer surface of the limiting rod is slidably inserted into one end of the inner support plate, and the inner wall of the outer support plate is slidably inserted into one end of the inner support plate.

[0019] Through the above technical solution, the insertion of the inner support plate and the outer support plate facilitates the relative or opposite movement of the clamping rollers, and the sliding insertion between the limiting rod and the inner support plate facilitates the synchronous lifting and lowering of the inner support plate by the lifting and lowering of the outer support plate.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting up a clamping device, it is possible to clamp both sides of the electrical equipment that is relatively high. The clamping motor drives the clamping screw to rotate, which in turn drives the moving slider to move left and right, allowing the clamping roller on the moving slider to move. This makes it easy to adjust according to the size of the electrical equipment. The outer surface of the clamping roller is covered with a rubber sleeve to reduce damage to the electrical equipment. This solves the technical problem that existing electrical installation and hoisting equipment fixes electrical equipment by squeezing, which can easily cause deformation of the electrical equipment shell and affect the subsequent use of the electrical equipment.

[0022] 2. By setting up a support device, electrical equipment can be supported. The outer support plate can be raised and lowered under the rotation of the support screw. The inner support plate and the outer support plate are slidably connected, which facilitates the raising and lowering of the outer support plate to drive the inner support plate to rise and fall synchronously. At the same time, it does not affect the relative or opposite movement of the outer and inner support plates. Adjusting the rotation of the screw can drive the moving plate to move, and then disengage the bevel gear between the transmission bevel gear and the transmission rod, so that the rotation of the clamping screw cannot drive the rotation of the support screw. Thus, a clamping motor can selectively drive the clamping screw and the support screw to rotate synchronously. This solves the technical problem that existing electrical installation and hoisting equipment cannot support the bottom of electrical equipment, which can easily cause electrical equipment to fall off, resulting in safety accidents and damage to electrical equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-4 An electrical installation hoisting device includes a limiting frame 1, and a clamping device is provided on the outer surface of the limiting frame 1. The clamping device includes a clamping roller 23, which clamps the electrical equipment to be hoisted.

[0030] In order to automatically adjust the position of the clamping rollers 23, the clamping device also includes a clamping screw 2. The two ends of the clamping screw 2 are rotatably connected to the outer surface of the limiting frame 1 through bearings. A clamping motor 21 is fixedly installed on the outer surface of the limiting frame 1. One end of the output shaft of the clamping motor 21 is fixedly installed with one end of the clamping screw 2. A movable slider 22 is threadedly connected to the outer surface of the clamping screw 2. The inner wall of the movable slider 22 is slidably inserted into the outer surface of the limiting frame 1. One end of the multiple clamping rollers 23 is fixedly installed with the outer side of the limiting frame 1 and the outer side of the movable slider 22, respectively.

[0031] In order to adjust the hoisting center according to the position of different electrical equipment, the outer surface of the limit frame 1 is hinged with an adjusting rod 24 by a pin. One end of the adjusting rod 24 is hinged to the upper surface of the movable slider 22 by a pin. A connecting lifting ring 25 is fixedly installed at the hinge of the adjusting rod 24. In order to lift the limit frame 1, a lifting rope 26 is passed through the lifting hole of the connecting lifting ring 25. A lifting plate 27 is fixedly installed on the outer surface of the lifting rope 26. In order to fix the electrical equipment, a lifting hook 28 is fixedly installed on the outer surface of the lifting plate 27 by bolts.

[0032] By setting up a clamping device, the electrical equipment can be clamped on both sides. The clamping motor 21 drives the clamping screw 2 to rotate, which in turn drives the moving slider 22 to move left and right, allowing the clamping roller 23 on the moving slider 22 to move. This facilitates adjustment according to the size of the electrical equipment. The outer surface of the clamping roller 23 is fitted with a rubber sleeve to reduce damage to the electrical equipment. This solves the technical problem that existing electrical installation and hoisting equipment fixes electrical equipment by squeezing, which easily causes deformation of the electrical equipment shell and affects the subsequent use of the electrical equipment.

[0033] The limiting frame 1 is equipped with a support device inside, which includes an outer support plate 36 and an inner support plate 37. The outer support plate 36 and the inner support plate 37 support the electrical equipment that needs to be hoisted.

[0034] In order to support the electrical equipment, the support device also includes an adjusting screw 3. The adjusting screw 3 is rotatably connected to the upper surface of the limiting frame 1 through a bearing seat. A movable plate 31 is threadedly connected to the outer surface of the adjusting screw 3. The outer surface of the movable plate 31 is slidably inserted into the inner wall of the limiting frame 1. A transmission bevel gear 32 is rotatably connected to the outer surface of the limiting frame 1 through a bearing. The transmission bevel gear 32 is slidably inserted into one end of the clamping screw 2.

[0035] In order to automatically adjust the position of the outer support plate 36 and the inner support plate 37, the inner wall of the limiting frame 1 is rotatably connected to a transmission rod 33 with a bevel gear through a bearing, and the bevel gear of the transmission rod 33 meshes with the transmission bevel gear 32.

[0036] In order to provide stable support for the electrical equipment, a support screw 34 with bevel gear is rotatably connected to the inner wall of one side of the clamping roller 23 via a bearing. The bevel gear of the support screw 34 meshes with the bevel gear of the transmission rod 33. A limit rod 35 is fixedly installed on the inner wall of the other side of the clamping roller 23.

[0037] In order to provide stable support for the inner support plate 37 and the outer support plate 36, the outer surface of the support screw 34 is threaded to one end of the outer support plate 36, the outer surface of the limiting rod 35 is slidably inserted into one end of the inner support plate 37, and the inner wall of the outer support plate 36 is slidably inserted into one end of the inner support plate 37.

[0038] By setting up a support device, electrical equipment can be supported. The outer support plate 36 can be raised and lowered under the rotation of the support screw 34. The inner support plate 37 is slidably inserted with the outer support plate 36, which facilitates the raising and lowering of the outer support plate 36 to drive the inner support plate 37 to rise and fall synchronously. At the same time, it does not affect the relative or opposite movement of the outer support plate 36 and the inner support plate 37. Adjusting the rotation of the screw 3 can drive the moving plate 31 to move, thereby disengaging the bevel gear between the transmission bevel gear 32 and the transmission rod 33. This prevents the rotation of the clamping screw 2 from driving the rotation of the support screw 34. Thus, a clamping motor 21 can selectively drive the clamping screw 2 and the support screw 34 to rotate synchronously. This solves the technical problem that existing electrical installation and hoisting equipment cannot support the bottom of electrical equipment, which can easily cause the electrical equipment to fall off, resulting in safety accidents and damage to the electrical equipment.

[0039] Working principle: When hoisting electrical equipment, after securing the hoisting rope 26 to the hoisting equipment, the electrical equipment is placed on the upper surface of the outer support plate 36 and the inner support plate 37. The clamping motor 21 on the limit frame 1 drives the clamping screw 2 to rotate. The clamping screw 2 drives the moving slider 22 to move on the limit frame 1, and at the same time, it drives the transmission bevel gear 32 on the moving plate 31 to rotate, which drives the transmission rod 33 to rotate, which drives the support screw 34 in the clamping roller 23 to rotate, and drives the outer support plate 36 to rise. The outer support plate 36 drives the inner support plate 37 to rise, and the outer support plate 36 and the inner support plate 37 are inserted together. After the outer support plate 36 and the inner support plate 37 reach the set height, the adjusting screw 3 is rotated. The adjusting screw 3 drives the moving plate 31 to move. The transmission bevel gear 32 disengages from the bevel gear on the transmission rod 33, and the supporting screw 34 stops rotating. After the clamping roller 23 on the moving slider 22 contacts the electrical equipment, the clamping roller 23 stops moving. The electrical equipment is fixed by hanging the hook 28 on the lifting ring of the electrical equipment.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
