Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to an adjusting mechanism and a lifting stability device. Background Art

[0002] The transformer water cooler is the most important auxiliary equipment of the transformer, which is mainly a device for cooling the transformer. Once the water quality passing through the cooler is unqualified, causing the inner wall water pipes of the cooler to be blocked, the water flow speed to slow down or be intercepted, then the operating oil and winding temperature of the transformer will continue to rise, leading to warnings or even trips of the transformer oil and winding temperature protection, bringing irreparable major losses and impacts. Therefore, it is very important to regularly maintain the cooler device daily. During the maintenance of the cooler, it is necessary to disassemble the upper end cover for inspection, cleaning, and dredging of each inner wall water pipe. The end cover weighs about 100 kg. Due to the limitation of the on-site environment, there is no reliable hanging point above the cooler device for hoisting the end cover. Lifting it manually or reinstalling it has potential safety hazards and is likely to cause personal and equipment injuries. Therefore, in order to ensure personal and equipment safety during daily maintenance work, a hoisting device is needed to hoist the cooler end cover.

[0003] The existing hoisting devices use electric hoists or winches as the hoisting power source, and are connected to the lifting ring through steel wires or chains to achieve the hoisting of the end cover. However, it is difficult to quickly locate the cooler end cover at different positions for hoisting. During the hoisting process, if an accidental power failure or mechanical failure occurs, it may cause the cooler end cover to fall, resulting in a safety accident. Moreover, during the operation of the overall device, it may shift or tilt, increasing the risk of accidental falling. Summary of the Utility Model

[0031] Embodiment 1

[0032] Referring to Figures 1-7 , which is the first embodiment of the present utility model. This embodiment provides an adjusting mechanism, including an adjusting assembly 100, which includes a mounting member 101 for receiving a lifting member 102, a lifting member 102 disposed on the mounting member 101 to enable the height of an adjusting member 103 and a winding member 104 to be adjustable, an adjusting member 103 disposed on the mounting member 101 for angle adjustment to position the cooler end cover by a locking member 202, and a winding member 104 disposed on the mounting member 101; and an anti - falling assembly 200, which includes a rotating member 201 disposed on the adjusting member 103 that rotates due to the winding of the winding member 104, and a locking member 202 disposed on the adjusting member 103 for locking the rotating member 201 to prevent the rotating member 201 from rotating in the reverse direction.

[0033] Specifically, the installation member 101 includes a base 101a, a universal wheel 101b rotatably connected to the bottom of the base 101a, a lower column 101c rotatably connected to the top of the base 101a, an upper column 101d slidably connected to the inside of the lower column 101c, a support rod 101e rotatably connected to one side of the upper column 101d, and a slide rail 101f provided on the top of the base 101a. The universal wheel 101b is used to drive the whole device to move. A plurality of universal wheels 101b are provided and are symmetrically arranged. The lower column 101c is hollow and is used to carry the lifting member 102 and provide guidance for the upper column 101d. The upper column 101d is hollow, and the size of the upper column 101d is adapted to the size of the opening of the lower column 101c. One end of the support rod 101e away from the upper column 101d is slidably connected to the slide rail 101f, and the slide rail 101f provides guidance for the support rod 101e.

[0034] Further, the lifting member 102 includes a threaded rod 102a rotatably connected to the lower column 101c, a first bevel gear 102b fixedly connected to the threaded rod 102a, a rocker 102c rotatably connected to the lower column 101c, and a second bevel gear 102d fixedly connected to the end of the rocker 102c inside the lower column 101c. The upper column 101d is threadedly connected to the threaded rod 102a. Rotation of the threaded rod 102a drives the upper column 101d to move. The rocker 102c drives the second bevel gear 102d to rotate in the lower column 101c, and the first bevel gear 102b and the second bevel gear 102d are meshed with each other.

[0035] Further, the adjusting member 103 includes a base 103a fixedly connected to the top of the upper column 101d, a worm gear 103b fixedly connected to the base 103a, a bracket 103c rotatably connected to the base 103a, a motor 103d fixedly connected to the bracket 103c, and a worm 103e fixedly connected to the output end of the motor 103d. The base 103a provides guidance for the bracket 103c. The bracket 103c is guided by the base 103a to adjust the opening angle on the base 103a. A vertical plate is provided on the bracket 103c. The motor 103d provides driving force for the worm 103e. One end of the worm 103e away from the motor 103d is rotatably connected to the bracket 103c, and the worm 103e is meshed with the worm gear 103b.

[0036] Further, the winding member 104 includes a first fixed pulley 104a rotatably connected to the bracket 103c, a second fixed pulley 104b rotatably connected to the bracket 103c, a loading box 104c fixedly connected to one side of the upper column 101d, a winding wheel 104d rotatably connected in the loading box 104c, a steel wire rope 104e sleeved on the winding wheel 104d, a hook 104f fixedly connected to the steel wire rope 104e, and a first motor 104g fixedly connected to the loading box 104c. Both the first fixed pulley 104a and the second fixed pulley 104b are rotatably connected to a vertical plate provided on the bracket 103c. The steel wire rope 104e is simultaneously arranged on the first fixed pulley 104a and the second fixed pulley 104b. The loading box 104c is used to load the winding wheel 104d and the steel wire rope 104e. The rotation of the winding wheel 104d drives the steel wire rope 104e to wind thereon. The hook 104f hooks the cooler end cover. The output end of the first motor 104g is fixedly connected to the winding wheel 104d to provide driving force for the winding wheel 104d.

[0037] Operation process: When the rocker 102c is shaken, the rocker 102c drives the second bevel gear 102d to rotate. Since the second bevel gear 102d meshes with the first bevel gear 102b, the first bevel gear 102b drives the threaded rod 102a to rotate. When the threaded rod 102a rotates, the upper column 101d moves on the threaded rod 102a and is slidably connected in the lower column 101c to play a role in lifting. When the motor 103d is started, it drives the worm 103e fixedly connected to the output end of the motor 103d to rotate. Since the worm 103e meshes with the worm gear 103b and the worm gear 103b is fixed, the bracket 103c rotates on the base 103a with the start of the motor 103d to realize angle adjustment. Through the adjustment of height and angle, the hook 104f can quickly locate at the cooler end cover to be lifted, and the cooler end cover is hoisted. At this time, the first motor 104g is started, and the first motor 104g drives the winding wheel 104d to rotate. The rotation of the winding wheel 104d winds the steel wire rope 104e thereon. The steel wire rope 104e passes through the first fixed pulley 104a and the second fixed pulley 104b in sequence, driving the hook 104f to hoist the cooler end cover, solving the problem of difficult disassembly and assembly during maintenance or repair, effectively saving manpower, and ensuring the personal safety of the operator.

[0038] Embodiment 2

[0039] Refer to Figure 6, which is the second embodiment of the present utility model. Different from the previous embodiment: The rotating member 201 includes a ratchet wheel 201a rotatably connected to the end of the bracket 103c, and a circular groove 201b formed in the ratchet wheel 201a. The ratchet wheel 201a is used to connect with the locking member 202. Both the ratchet wheel 201a and the circular groove 201b are provided with two and are symmetrically arranged. The steel wire rope 104e is arranged in the two circular grooves 201b, and the size of the steel wire rope 104e is adapted to the size of the two circular grooves 201b. When the steel wire rope 104e is wound up, it drives the two ratchet wheels 201a to rotate.

[0040] Specifically, the locking member 202 includes a spring 202a fixedly connected to the bracket 103c, a locking rod 202b fixedly connected to the spring 202a, a card slot 202c formed in the locking rod 202b, and an electric push rod 202d fixedly connected to one side of the bracket 103c. The spring 202a is used to provide elastic force for the locking rod 202b. A plurality of springs 202a are provided and are symmetrically arranged. The locking rod 202b is used to lock and limit the ratchet wheel 201a. The ratchet wheel 201a is arranged in the card slot 202c. A plurality of card slots 202c are provided and are horizontally and evenly distributed. The output end of the electric push rod 202d is slidably connected to the bracket 103c, and the output end of the electric push rod 202d is fixedly connected to the locking rod 202b. Both the locking rod 202b and the electric push rod 202d are provided with two and are symmetrically arranged.

[0041] The remaining structures are the same as those in Embodiment 1.

[0042] Operation process: When the steel wire rope 104e is wound up to lift the cooler end cover through the hook 104f, the steel wire rope 104e moves upward and drives the two ratchet wheels 201a to rotate in the reverse direction. Driven by the ratchet teeth of the two ratchet wheels 201a, the locking rod 202b is toggled through the card slot 202c. Under the elastic force of the spring 202a, the two locking rods 202b move left and right. When an accidental power failure or mechanical failure occurs, resulting in the fall of the cooler end cover, driven by the weight of the cooler end cover, the steel wire rope 104e moves downward, driving the two ratchet wheels 201a to rotate towards each other. At this time, under the limitation of the card slot 202c on the ratchet teeth of the two ratchet wheels 201a, the two ratchet wheels 201a cannot rotate and clamp the steel wire rope 104e to prevent the cooler end cover from falling, effectively ensuring the safety during the lifting process. The electric push rod 202d is started, pulling the two locking rods 202b to move in the reverse direction, and the spring 202a is tightened to cancel the locking and limiting of the ratchet wheel 201a.

[0043] Embodiment 3

[0044] Refer to Figure 7, which is the third embodiment of the present utility model. Different from the above embodiments, this embodiment provides a lifting stability device, including the above-mentioned adjusting mechanism, and further including a stabilizing component 300, which includes a driving member 301 disposed on the mounting member 101 to provide driving force for the pressing member 302, and a pressing member 302 disposed on the mounting member 101, which is driven by the driving member 301 to press against the ground.

[0045] Specifically, the driving member 301 includes a second motor 301a fixedly connected to the bottom of the base 101a, a lead screw 301b fixedly connected to the output end of the second motor 301a, and a moving plate 301c threadedly connected to the lead screw 301b. The second motor 301a provides driving force for the lead screw 301b. When the lead screw 301b rotates, the moving plate 301c moves on the lead screw 301b, and the moving plate 301c drives the pressing member 302 to press down.

[0046] Furthermore, the pressing member 302 includes an L-shaped rod 302a rotatably connected to the moving plate 301c, and a suction cup 302b rotatably connected to the L-shaped rod 302a. The L-shaped rod 302a is rotatably connected to the base 101a. The L-shaped rod 302a drives the suction cup 302b to move downward, and the suction cup 302b adsorbs on the ground through vacuum suction. Both the L-shaped rod 302a and the suction cup 302b are provided with two and are symmetrically arranged.

[0047] The remaining structures are the same as those in Embodiment 2.

[0048] Operation process: When the whole device is pushed to the cooler end cover to be lifted, start the second motor 301a. The second motor 301a drives the lead screw 301b to rotate. The moving plate 301c moves upward as the lead screw 301b rotates. The two L-shaped rods 302a rotatably connected to the moving plate 301c are driven by the moving plate 301c and rotate on the base 101a. The suction cups 302b rotatably connected to the ends of the L-shaped rods 302a move downward and adsorb on the ground through vacuum suction, increasing the grounding area, effectively improving the stability of the whole device, ensuring the stability of the device during the lifting process, preventing it from shifting or tilting, and reducing the occurrence of potential safety hazards. On the contrary, when the second motor 301a rotates in reverse, the suction cups 302b cancel the adsorption on the ground.
