[0051] See also Figure 1-4 As shown, according to an embodiment of the present application, a lifting device for overhauling an electric brake switch is provided, comprising:

[0052] Base 1;

[0053] A hoisting assembly 2, the hoisting assembly 2 is arranged on the base 1, and the hoisting assembly 2 includes an electric hoist 21;

[0054] The grab assembly 3 is arranged on the electric hoist 21, and the grab assembly 3 is connected with the electric brake at multiple positions.

[0055] The hoisting device for the maintenance of the electric brake switch provided in this embodiment includes a base 1, a hoisting assembly 2 and a grabbing assembly 3, wherein the base 1 provides stable support for the hoisting assembly 2 and the grabbing assembly 3. The base 1 can withstand the weight and impact force during the hoisting process. The electric hoist 21 in the hoisting assembly 2 has a strong lifting capacity and can easily lift the electric brake switch from the cabinet. It is driven by a motor to drive a chain or a wire rope for lifting and lowering operations, and has the advantages of simple operation and controllable speed. During the hoisting process, the electric hoist 21 can be precisely adjusted in position as needed to ensure that the electric brake switch can be lifted and moved smoothly. The grabbing assembly 3 is arranged on the electric hoist 21 and can be connected to the electric brake switch from multiple positions. The grabbing is made more firm and reliable, and the electric brake switch is effectively prevented from shaking or falling off during the hoisting process. The grabbing assembly 3 is usually composed of a plurality of grabbing arms or clamps, which can be adjusted according to the shape and size of the electric brake switch to achieve the best grabbing effect.

[0056] In actual application, the operation process of the lifting device is as follows: First, place the base 1 in a suitable position and ensure that it is stable and reliable. Then, lower the grabbing assembly 3 to the position of the electric brake switch by operating the electric hoist 21. Next, adjust the position of the grabbing assembly 3 so that it is connected to multiple positions of the electric brake switch. Finally, slowly lift the electric brake switch by the electric hoist 21 and move it to the designated maintenance position. Through the setting of the base 1, the lifting assembly 2 and the grabbing assembly 3, an efficient, safe and reliable solution is provided for the maintenance of the electrical brake switch. This lifting device not only improves the maintenance efficiency and reduces the labor intensity, but also reduces the risk of equipment damage, and provides a strong guarantee for the stable operation of electrical equipment.

[0057] The crawling component 3 includes:

[0058] Fixed plate;

[0059] A first fixed tube 31, which is disposed on a fixed plate, and first grabbing rods 32 are slidably disposed on both sides of the first fixed tube 31, and a first hook 33 is disposed on the first grabbing rod 32;

[0060] The second fixed tube 34 is arranged on the fixed plate. The second fixed tube 34 and the first fixed tube 31 are arranged crosswise. Second grabbing rods 35 are slidably arranged on both sides of the second fixed tube 34 . The second grabbing rods 35 are provided with second hooks 36 .

[0061] In this technical solution, the fixing plate provides a fixing platform for the first fixing tube 31 and the second fixing tube 34. The fixing plate is usually made of high-strength material and can withstand large tension and pressure to ensure that it will not be deformed or damaged during the lifting process. The first fixing tube 31 is set on the fixing plate, and the first grabbing rods 32 slidingly arranged on both sides thereof can be flexibly adjusted according to the size and shape of the electrical brake switch. The first hook 33 on the first grabbing rod 32 can be connected to a specific part of the electrical brake switch to achieve stable grabbing. By sliding to adjust the position of the first grabbing rod 32, electrical brake switches of different specifications can be adapted from the first direction, thereby improving the versatility of the lifting device.

[0062] The second fixing tube 34 is also arranged on the fixing plate, and the cross arrangement with the first fixing tube 31 increases the stability of the grabbing. The second grabbing rods 35 and the second hooks 36 arranged on both sides of the second fixing tube 34 cooperate with the first grabbing rods 32 and the first hooks 33 to grab the electric brake switch from multiple directions. This multi-directional grabbing method can effectively disperse the stress during the hoisting process and prevent the electric brake switch from tilting or shaking during the hoisting process.

[0063] When in use, the operator can flexibly adjust the positions of the first grabbing rod 32 and the second grabbing rod 35 according to the specific situation of the electric brake switch, ensuring that the first hook 33 and the second hook 36 can be accurately connected to the electric brake switch. At the same time, the sliding grabbing rod allows the hoisting device to adapt to electric brake switches of different sizes and shapes, and the telescopic lengths of the first grabbing rod 32 and the second grabbing rod 35 on both sides can be adjusted according to the center of gravity of the electric brake switch, so as to keep the center of the electric brake switch close to the center of the first fixed tube 31 or the second fixed tube 34 when hoisting, thereby improving the stability and versatility during the hoisting process.

[0064] The crawling component 3 also includes:

[0065] A first fastener 37, which is disposed on the first fixing tube 31 and is used to fix the first grabbing rod 32;

[0066] The second fastener 38 is disposed on the second fixing tube 34 and is used to fix the second grabbing rod 35 .

[0067] In this technical solution, the first fastener 37 is arranged on the first fixing tube 31, and its main function is to fix the first grabbing rod 32. When the first grabbing rod 32 is adjusted to a suitable position corresponding to a specific part of the electric brake switch, the first fastener 37 can tightly fix the first grabbing rod 32 to prevent it from sliding or shifting during the hoisting process. The first fastener 37 is usually in the form of a bolt, a nut or a clamping device, which can provide sufficient clamping force to ensure the stability of the first grabbing rod 32. In this way, the connection between the first hook 33 and the electric brake switch can be firmly and reliably ensured to avoid accidental falling off during the hoisting process.

[0068] Similarly, the second fastener 38 is disposed on the second fixing tube 34 to fix the second grabbing rod 35. The second fastener 38 has the same function as the first fastener 37. After the second grabbing rod 35 is adjusted to a certain position, it can be firmly fixed to the second fixing tube 34 to ensure a stable connection between the second hook 36 and the electric brake switch. The second fastener 38 can also be fixed in different ways according to actual needs to meet different usage requirements.

[0069] When in use, the operator only needs to tighten the corresponding fasteners after adjusting the positions of the first grabbing rod 32 and the second grabbing rod 35 to complete the fixation. This design not only improves the operating efficiency of the hoisting device, but also enhances the safety and reliability of the device.

[0070] The crawling component 3 also includes:

[0071] The hanging ring 39 is disposed in the middle of the first fixed tube 31 and the second fixed tube 34 , and the hanging ring 39 is connected to the electric hoist 21 .

[0072] In this technical solution, the hanging ring 39 is arranged in the middle of the first fixed tube 31 and the second fixed tube 34, which can ensure that the force of the entire grabbing assembly 3 is uniform during the lifting process. The hanging ring 39 is usually made of high-strength metal material and has sufficient load-bearing capacity to withstand the weight of the electric brake switch and the impact force that may be generated during the lifting process. The hanging ring 39 is connected to the electric hoist 21 to connect the grabbing assembly 3 and the lifting assembly 2. Through the setting of the hanging ring 39, the lifting force of the electric hoist 21 can be effectively transmitted to the grabbing assembly 3, thereby realizing the smooth lifting of the electric brake switch. The hanging ring 39 is connected to the hook at the bottom of the electric hoist 21 to ensure that the connection is firm and reliable and will not loosen during the lifting process.

[0073] Lifting assembly 2 includes:

[0074] A support column 22, a mounting seat 23 is provided on the top of the support column 22, and a mounting shaft is provided on the mounting seat 23;

[0075] A shaft sleeve 24, the shaft sleeve 24 is arranged on the mounting shaft;

[0076] A telescopic boom 25, wherein a first end of the telescopic boom 25 is disposed on the shaft sleeve 24, and an electric hoist 21 is disposed on a second end of the telescopic boom 25;

[0077] The driving part 26 is disposed on the mounting seat 23 and is used to drive the shaft sleeve 24 to rotate.

[0078] In this technical solution, the support column 22 is used to support the telescopic boom 25, and the mounting seat 23 on the top of the support column 22 provides a solid mounting platform for the mounting shaft and other components. The shaft sleeve 24 is connected to the mounting seat 23 through the mounting shaft, providing a connection point and rotation support for the telescopic boom 25. The setting of the telescopic boom 25 enables the hoisting device to adapt to hoisting tasks at different distances. The first end is set on the shaft sleeve 24, so that the telescopic boom 25 can change direction as the shaft sleeve 24 rotates. The electric hoist 21 set on the second end is responsible for providing lifting power. The telescopic boom 25 can be adjusted in length according to actual needs, so as to realize the hoisting of electric brake switches at different positions.

[0079] The driving unit 26 is arranged on the mounting seat 23, and its function is to drive the shaft sleeve 24 to rotate. The driving unit 26 usually adopts a power source such as a motor or a hydraulic device, and is connected to the shaft sleeve 24 through a transmission mechanism. The control of the driving unit 26 can realize the rotation of the shaft sleeve 24, thereby adjusting the direction of the telescopic boom 25, making the hoisting operation more flexible and convenient. In actual operation, the operator can adjust the position of the telescopic boom 25 by controlling the driving unit 26, so as to turn and hoist the electric brake switch to the target maintenance position, thereby improving the convenience of operation.

[0080] The driving unit 26 includes:

[0081] A driving member 261, the driving member 261 is disposed on the supporting column 22;

[0082] A first gear 262, the first gear 262 is connected to an output end of the driving member 261;

[0083] The second gear 263 is disposed on the shaft sleeve 24 , and the first gear 262 is meshedly connected with the second gear 263 .

[0084] In this technical solution, the driving member 261 is fixedly mounted on the support column 22 as the power source of the driving part 26. The first gear 262 is connected to the output end of the driving member 261 to transmit the power of the driving member 261 to the second gear 263. The second gear 263 is arranged on the sleeve 24 and meshes with the first gear 262. The parameters such as the number of teeth and the module of the second gear 263 match the first gear 262 to achieve a precise transmission ratio. When the driving member 261 is working, the first gear 262 rotates, and the second gear 263 is driven to rotate through the meshing action, thereby rotating the sleeve 24. In use, after the driving member 261 is started, the output end drives the first gear 262 to rotate. The first gear 262 meshes with the second gear 263, and transmits the power to the second gear 263, so that the sleeve 24 rotates. The rotation of the sleeve 24 drives the telescopic boom 25 to change direction, thereby realizing the steering of the suspended electrical brake switch, which is convenient for moving it to the target position, and can meet the needs of the hoisting device under different working conditions.

[0085] Furthermore, the driving member 261 is a driving motor.

[0086] The telescopic boom 25 comprises:

[0087] A first suspension rod 251, a first end of the first suspension rod 251 is connected to the shaft sleeve 24;

[0088] A second suspension rod 252, wherein a first end of the second suspension rod 252 is slidably disposed inside the first suspension rod 251, and the electric hoist 21 is disposed on a second end of the second suspension rod 252;

[0089] The hydraulic rod 253 is disposed in the first suspension rod 251 , and an output end thereof is connected to a first end of the second suspension rod 252 .

[0090] In this technical solution, the connection between the first suspension rod 251 and the shaft sleeve 24 ensures that the entire telescopic suspension rod 25 can be flexibly rotated under the action of the driving part 26, so that the lifting angle can be adjusted according to actual needs, which greatly improves the convenience and accuracy of lifting. Whether in a narrow space or a complex working environment, the electric hoist 21 and the grab assembly 3 can be easily and accurately aligned with the electric brake switch for lifting operations.

[0091] The second boom 252 is set to slide inside the first boom 251. This allows the telescopic boom 25 to change in length without increasing too much volume, so as to meet the lifting requirements of different distances. The hydraulic rod 253, as a power source for telescoping, has strong thrust and stability. The hydraulic system can provide uniform and controllable force, so that the telescoping process of the second boom 252 is smooth and reliable. During the lifting process, the hydraulic rod 253 can accurately adjust the position of the output end according to actual conditions, thereby achieving fine-tuning of the length of the second boom 252. This precise control is crucial to avoid collision with the cabinet and ensure the safe lifting of the electrical brake switch.

[0092] The overall structure of the telescopic boom 25 is arranged to ensure the realization of the function without taking up too much space. In actual use, it is convenient to carry and install, and can be quickly put into the maintenance work of the electric brake switch.

[0093] The hoisting assembly 2 also includes:

[0094] Tie rods 27 , at least one tie rod 27 is disposed between the shaft sleeve 24 and the first suspension rod 251 .

[0095] In this technical solution, at least one tie rod 27 is arranged between the sleeve 24 and the first suspension rod 251, which plays an important role in connection and reinforcement. The tie rod 27 is usually made of high-strength metal material with good tensile strength and toughness. It can withstand the tension and torsion generated during the lifting process, and prevent relative displacement or deformation between the sleeve 24 and the first suspension rod 251.

[0096] During the hoisting operation, when the telescopic suspension rod 25 bears the weight of the electric brake switch, the tensioning rod 27 can effectively disperse the stress and reduce the pressure on the sleeve 24 and the first suspension rod 251. The overall strength and stability of the hoisting assembly 2 are improved to ensure the safety and reliability of the hoisting process.

[0097] It is understandable that in actual use, the number and arrangement of the tie bars 27 can be adjusted according to the specific specifications and use requirements of the lifting device. Reasonable arrangement of the tie bars 27 can maximize the performance and reliability of the lifting assembly 2, and also facilitate installation and maintenance.

[0098] The base 1 comprises:

[0099] The base body 11, the support column 22 is disposed on the base body 11;

[0100] Driving wheels 12, which are arranged at the four corners of the bottom of the seat body 11;

[0101] The fixing parts 13 are symmetrically arranged on both sides of the base 1 in pairs.

[0102] In this technical solution, the seat body 11 provides a stable installation foundation for the support column 22. The seat body 11 is usually made of a strong and durable material, has sufficient strength and weight, and can withstand various forces and pressures of the hoisting device during operation. The driving wheels 12 are arranged at the four corners of the bottom of the seat body 11, which greatly facilitates the movement of the hoisting device. When the hoisting device needs to be moved, the operator can easily push or pull the device to quickly reach the working position. The driving wheel 12 can also be equipped with a brake device to ensure the stable parking of the device during the hoisting process to prevent accidental movement. The fixing parts 13 are symmetrically arranged on both sides of the base 1 in pairs, and their function is to further enhance the stability of the base 1 during the hoisting process. The fixing part 13 can be in the form of anchor bolts, hydraulic legs, etc., and through a firm connection with the ground, the base 1 is prevented from shaking or tilting during the hoisting process. When using the fixing part 13, the operator can adjust and fix it according to the actual situation to ensure the safety and reliability of the hoisting device during operation.

[0103] The fixing portion 13 includes:

[0104] A limiting rod 131, the limiting rod 131 is arranged on the side wall of the base 1;

[0105] The positioning rod 132 is disposed on the limiting rod 131 , and the positioning rod 132 is threadedly connected to the limiting rod 131 .

[0106] In this technical solution, a limit rod 131 is arranged on the side wall of the base 1 and extends outward to improve the ability to fix the base 1. The limit rod 131 is usually made of a solid metal material, has sufficient strength and rigidity, and can withstand greater pressure and tension. The positioning rod 132 is arranged on the limit rod 131 and is threadedly connected to the limit rod 131. This connection method allows the positioning rod 132 to be adjusted in height by rotation to adapt to different ground conditions and work requirements. The positioning rod 132 is usually made of high-strength metal material, and its bottom can be designed to be sharp or disc-shaped to increase the stability of the fixation. When in use, the operator can adjust the height of the positioning rod 132 according to actual conditions so that it is in close contact with the ground, thereby effectively preventing the base 1 from moving or shaking during the lifting process.

[0107] When in use, after the hoisting device reaches the working position, the operator can rotate the positioning rod 132 to gradually lower it and fix it on the ground, and the friction between it and the ground gradually increases, thereby firmly fixing the base 1 on the ground. During the hoisting process, even if it is subjected to a large external force, the fixing part 13 can effectively maintain the stability of the base 1, ensuring the safety of the hoisting operation.

[0108] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
