Description

Technical Field

[0001] The present invention relates to the technical field of hoisting of power equipment, and particularly to a hoisting framework for the installation of large power equipment. Background Art

[0002] A power transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components include a primary coil, a secondary coil, and an iron core (magnetic core). Through electromagnetic induction, it transfers electrical energy from one circuit to another, and at the same time realizes functions such as voltage transformation, current transformation, and impedance transformation. Its appearance is usually a cuboid-shaped shell, which is generally made of metal and coated with protective paint on the surface, and the color is mostly gray or blue, etc. When conducting import and export trade of power transformers, hoisting is usually required at ports.

[0003] According to a large power equipment installation hoisting framework disclosed in Chinese Patent with the publication number "CN215439287U", which includes a box body, a clamping component, a placement plate, and a buffer component. The clamping component is arranged inside the box body. A sliding rod is fixedly connected inside the box body. A slider is slidably connected to the outer wall of the sliding rod. A spring is sleeved on the outer wall of the sliding rod. A first rotating shaft is installed on the outer wall of the slider. A lifting rod is connected through the outer wall of the first rotating shaft. One end of the lifting rod is connected through a second rotating shaft. A clamping plate is installed on the outer wall of the second rotating shaft. The buffer component is arranged inside the box body. A T-shaped sliding rod is fixedly connected to the bottom of the box body. A sliding plate is slidably connected to the outer wall of the T-shaped sliding rod. A shock-absorbing spring is sleeved on the outer wall of the T-shaped sliding rod. For this large power equipment installation hoisting framework, the power equipment is clamped and fixed through the clamping component to prevent the equipment from falling, causing danger to personnel and damage to power equipment. The impact generated during transportation can be buffered through the buffer component to prevent damage to the hoisting framework and power equipment.

[0004] When the above patent is in use, the clamping plate is supported by a spring, and the equipment is clamped by pushing the clamping plates closer to each other. During the hoisting process, the equipment shakes as it rises with the hoisting, thus squeezing the clamping plates and causing uneven force and loosening, which may lead to potential safety hazards during the lifting process. Therefore, a hoisting framework for the installation of large power equipment is proposed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a hoisting framework for the installation of large power equipment in view of the above-mentioned deficiencies in the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: A hoisting framework for the installation of large power equipment, including a base, and further including: A protective frame, arranged on the top of the base, for protecting the power transformer being hoisted; A door, arranged on the front of the protective frame; A hanging ring is arranged at the top of the protective frame and is used for fixing the tower crane hook lock.

The bottom ends of the two movable rods are respectively hinged with the tops of the two movable plates. Four ropes are fixedly connected to the inner wall of the protective frame. The other ends of the four ropes away from the protective frame penetrate through the movable plate and are respectively fixedly connected to the four second sliders. A fixed pulley is arranged on the movable plate. The middle part of the rope is wound around the fixed pulley.

[0009] Preferably, a cleaning mechanism is arranged on the bottom first clamping plate. The cleaning mechanism includes a rotating rod. The rotating rod is rotatably connected to the front and back sides of the bottom first clamping plate through bearings. A second clamping plate is fixedly connected to the rotating rod. A telescopic rod is fixedly connected to the bottom of the second clamping plate. A ball is arranged at the bottom end of the telescopic rod. The ball is slidably connected to the upper surface of the base.

[0010] Preferably, a rack is fixedly connected to the top of the base. A gear is fixedly connected to the middle part of the telescopic rod. The gear meshes with the rack. During the relative movement of the two first clamping plates on both sides, the rotating rod and the second clamping plate are driven to move. The movement of the second clamping plate drives the telescopic rod and the gear to move. During the movement of the gear, it meshes with the rack and rotates. The rotation of the gear drives the telescopic rod and the second clamping plate to rotate, and the front and back sides of the power transformer are fixed by the second clamping plates on the front and back sides, further improving the stability of the power transformer during hoisting.

[0011] Preferably, an air pump is fixedly connected to one side of the second clamping plate. An air pipe is fixedly connected to the top of the air pump. The top end of the air pipe is fixedly connected with a nozzle. The nozzle is fixedly connected to the second clamping plate. During the rotation of the second clamping plate, gas is sprayed through the cooperation of the air pump, the air pipe and the nozzle, and the dust in the front and back and left and right directions of the power transformer is blown off by the air pressure, thereby further improving the friction force when the first clamping plate and the second clamping plate contact the outer wall of the power transformer, and further making the clamping more stable.

[0012] Preferably, a cleaning mechanism is provided above the first clamping plate, and the cleaning mechanism includes a sliding rod, one end of the sliding rod slides through the movable plate through a linear bearing, and the end of the sliding rod close to the first clamping plate is fixedly connected to the first top block, and the top of the first clamping plate is fixedly connected to the second top block, the first top block contacts the second top block, and one side of the first top block is fixedly connected to a pressure plate, and the second top block is driven to move upward during the upward movement of the top first clamping plate, and the second top block contacts the first top block during the upward movement and pushes the first top block toward the direction of the power transformer, and the first top block moves toward the direction of the power transformer, driving the pressure plate to move toward the direction of the power transformer and contacting the top outer wall of the power transformer, thereby fixing the top of the power transformer by setting the pressure plate.

[0013] Preferably, the other end of the sliding rod away from the pressure plate is fixedly connected to the first fixed block, the outer sleeve of the sliding rod is provided with a spring, one end of the spring is fixedly connected to the first fixed block, and the other end of the spring away from the first fixed block is fixedly connected to the movable plate, and the spring is set to drive the sliding rod to rebound.

[0014] Preferably, the pressure plate is fixedly connected to a second fixed block on the other side away from the movable plate, and a roller brush is provided on the second fixed block. During the movement of the pressure plate, the dust on the top of the power transformer is cleaned by the roller brush, thereby increasing the friction between the pressure plate and the top outer wall of the power transformer, thereby further improving the clamping stability of the power transformer.

[0015] The present invention adopts the above technical solution to bring the following beneficial effects: 1. The invention achieves the effect of fixing the power transformer by setting a clamping mechanism and firmly clamping the power transformer from both sides through four first clamping plates. In the clamping process, when the movable plate drives the first clamping plate to move, the rope pulls the first clamping plate to move away from the center of the movable plate, so that the first clamping plate is close to the upper and lower sides when contacting the outer walls of the left and right sides of the power transformer, and the clamping force is evenly distributed, which further improves the clamping stability of the power transformer, thereby effectively reducing the safety hazards when the power transformer is hoisted.

[0016] 2. The invention sets a cleaning mechanism. When the first clamping plate moves relatively, it drives the rotating rod, the second clamping plate and related parts to move, and the gear and the rack mesh to rotate the second clamping plate, thereby achieving the effect of fixing the power transformer from both the front and rear sides. When the second clamping plate rotates, the air pump, the air pipe and the nozzle cooperate to spray gas to blow off the dust in the front and rear and left and right directions of the power transformer, thereby increasing the friction between the first clamping plate and the second clamping plate when they contact the outer wall of the power transformer, and further improving the clamping stability of the power transformer.

[0017] 3. The invention completes the fixation effect on the top of the power transformer by setting a cleaning mechanism. When the first clamping plate at the top moves upward, it drives the second top block, and then pushes the first top block so that the pressing plate contacts the outer wall of the top of the power transformer. During the movement of the pressing plate, the roller brush carried by it cleans the dust on the top of the power transformer, improving the friction between the pressing plate and the outer wall of the top of the power transformer, and further enhancing the clamping stability effect on the power transformer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-8, an embodiment of the present invention is: a hoisting frame for installing large-scale power equipment, including a base 1, and further including: A protective frame 2, arranged on the top of the base 1, for protecting the hoisted power transformer; A door 21, arranged on the front of the protective frame 2; A hanging ring 3, arranged on the top of the protective frame 2, for fixing the tower crane hook lock; A clamping mechanism 4, arranged inside the protective frame 2, for fixing the hoisted power transformer; Among them, the clamping mechanism 4 includes: Four first clamping plates 41, arranged above the base 1, for clamping and fixing the power transformer from both sides.

[0022] A first sliding groove 42 is formed on the top of the base 1, two first sliding blocks 43 are slidably connected in the first sliding groove 42, a movable plate 44 is fixedly connected to the top of the first sliding block 43, a second sliding groove 45 is formed on the opposite side of the two movable plates 44, two second sliding blocks 46 are slidably connected in the second sliding groove 45, and the four first clamping plates 41 are respectively fixedly connected to the four second sliding blocks 46.

[0023] The inner wall of the top of the protective frame 2 is fixedly connected with a hydraulic cylinder 47, the bottom end of the hydraulic cylinder 47 is hinged with two movable rods 48, the bottom ends of the two movable rods 48 are respectively hinged with the tops of the two movable plates 44, the inner wall of the protective frame 2 is fixedly connected with four ropes 49, the other ends of the four ropes 49 away from the protective frame 2 penetrate through the movable plate 44 and are respectively fixedly connected with the four second sliding blocks 46, and a fixed pulley 410 is arranged on the movable plate 44, and the middle part of the rope 49 is wound around the fixed pulley 410.

[0024] Working principle: First, open the door 21 and place the power equipment to be hoisted into the protective frame 2 and between the two movable plates 44. Then, start the hydraulic cylinder 47 to drive the top ends of the two movable rods 48 to move upward. The upward movement of the top ends of the two movable rods 48 drives the two movable plates 44 hinged to their bottom ends to move relatively with the first sliding blocks 43. The relative movement of the two movable plates 44 drives the four first clamping plates 41 on both sides to move relatively. During the relative movement of the four first clamping plates 41 on both sides, they will contact the outer walls of both sides of the power transformer and firmly clamp and fix the power transformer from both sides. When the movable plate 44 moves towards the power transformer, due to the traction of the ropes 49 on the first clamping plates 41 and the second sliding blocks 46, they will move away from the center of the movable plate 44. Therefore, when the four first clamping plates 41 on both sides contact the left and right outer walls of the power transformer, they will respectively approach the upper and lower sides of the power transformer, thereby further improving the clamping stability of the power transformer by evenly distributing the clamping force.

A second clamping plate 52 is fixedly connected to the rotating rod 51. A telescopic rod 53 is fixedly connected to the bottom of the second clamping plate 52. A ball is provided at the bottom end of the telescopic rod 53. The ball is slidably connected to the upper surface of the base 1. A rack 55 is fixedly connected to the top of the base 1. A gear 54 is fixedly connected to the middle of the telescopic rod 53. The gear 54 meshes with the rack 55. During the relative movement of the two side first clamping plates 41, the rotating rod 51 and the second clamping plate 52 are driven to move. The movement of the second clamping plate 52 drives the telescopic rod 53 and the gear 54 to move. During the movement of the gear 54, it meshes with the rack 55 and rotates. The rotation of the gear 54 drives the telescopic rod 53 and the second clamping plate 52 to rotate, and the front and rear sides of the power transformer are fixed by the front and rear second clamping plates 52, further improving the stability of the power transformer during hoisting.

[0026] A gas pump 56 is fixedly connected to one side of the second clamping plate 52. An air pipe 57 is fixedly connected to the top of the gas pump 56. The top end of the air pipe 57 is fixedly connected to a nozzle 58. The nozzle 58 is fixedly connected to the second clamping plate 52. During the rotation of the second clamping plate 52, gas is sprayed through the cooperation of the gas pump 56, the air pipe 57 and the nozzle 58, and the dust in the front, rear, left and right directions of the power transformer is blown off by air pressure, thereby further improving the friction force when the first clamping plate 41 and the second clamping plate 52 contact the outer wall of the power transformer, and further making the clamping more stable.

[0027] Working principle: During the relative movement of the two side first clamping plates 41, the rotating rod 51 and the second clamping plate 52 are driven to move. The movement of the second clamping plate 52 drives the telescopic rod 53 and the gear 54 to move. During the movement of the gear 54, it meshes with the rack 55 and rotates. The rotation of the gear 54 drives the telescopic rod 53 and the second clamping plate 52 to rotate, and the front and rear sides of the power transformer are fixed by the front and rear second clamping plates 52, further improving the stability of the power transformer during hoisting. During the rotation of the second clamping plate 52, gas is sprayed through the cooperation of the gas pump 56, the air pipe 57 and the nozzle 58, and the dust in the front, rear, left and right directions of the power transformer is blown off by air pressure, thereby further improving the friction force when the first clamping plate 41 and the second clamping plate 52 contact the outer wall of the power transformer, and further making the clamping more stable.

[0028] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, a cleaning mechanism 6 is arranged above the first clamping plate 41.

The top of the top first clamping plate 41 is fixedly connected with a second top block 63. The first top block 62 contacts the second top block 63. One side of the first top block 62 is fixedly connected with a pressing plate 64. During the upward movement of the top first clamping plate 41, the second top block 63 is driven to move upward. During the upward movement of the second top block 63, it contacts the first top block 62 and pushes the first top block 62 towards the power transformer. The movement of the first top block 62 towards the power transformer drives the pressing plate 64 to move towards the power transformer and contacts the outer wall of the top of the power transformer. Thus, the top of the power transformer is fixed by setting the pressing plate 64.

[0029] The other end of the slide bar 61 far from the pressing plate 64 is fixedly connected with a first fixing block 65. A spring 66 is sleeved on the outer part of the slide bar 61. One end of the spring 66 is fixedly connected with the first fixing block 65, and the other end of the spring 66 far from the first fixing block 65 is fixedly connected with the movable plate 44. By setting the spring 66, the slide bar 61 is driven to rebound.

[0030] The other side of the pressing plate 64 far from the movable plate 44 is fixedly connected with a second fixing block 67. A roller brush 68 is arranged on the second fixing block 67. During the movement of the pressing plate 64, the dust on the top of the power transformer is cleaned by the roller brush 68, so as to increase the friction between the pressing plate 64 and the outer wall of the top of the power transformer, and further improve the clamping stability of the power transformer.

[0031] Working principle: During the upward movement of the top first clamping plate 41, the second top block 63 is driven to move upward. During the upward movement of the second top block 63, it contacts the first top block 62 and pushes the first top block 62 towards the power transformer. The movement of the first top block 62 towards the power transformer drives the pressing plate 64 to move towards the power transformer and contacts the outer wall of the top of the power transformer. Thus, the top of the power transformer is fixed by setting the pressing plate 64. During the movement of the pressing plate 64, the dust on the top of the power transformer is cleaned by the roller brush 68, so as to increase the friction between the pressing plate 64 and the outer wall of the top of the power transformer, and further improve the clamping stability of the power transformer.
