Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment of power systems, and in particular to a lifting device with slideway adjustment. Background Art

[0002] The reliable disconnection of high-voltage circuit breakers plays a vital role in ensuring the safe and reliable operation of the power grid. The traditional high-voltage circuit breaker remote control tripping device effectively ensures that the high-voltage circuit breaker cannot be normally disconnected due to control failure caused by unknown factors. However, due to the differences in the models of switch cabinets and mechanism boxes of various substations, the positions of the circuit breaker opening and closing buttons are not the same. At this time, the operation and maintenance personnel need to adjust the height of the actuator rod for operation.

[0003] There are two traditional ways to fix the actuator rod of the remote control release device of a high-voltage circuit breaker. When the button of the circuit breaker emergency trip device is located low during on-site work, and the actuator rod of the remote control release device of the high-voltage circuit breaker is located at the top of the telescopic rod, the actuator rod needs to be removed and fixed to the fastening clamp on the telescopic rod. During the switching process, the screws need to be removed and the position of the clamp needs to be adjusted. The process is cumbersome and time-consuming. In addition, the clamp is not fixed firmly enough. If it slips during the operation, the actuator rod and the button will be inconsistent in position, and the operation cannot be completed. During this period of time, if the high-voltage circuit breaker cannot be reliably opened, it may cause dangerous accidents, and even serious personal injury.

[0004] In order to solve the above problems, it was decided to develop a positioning and mounting structure that is convenient for switching the actuator rod. Summary of the invention

[0005] The object of the present invention is to provide a lifting device with slideway adjustment, aiming at optimizing the positioning and installation structure of the existing actuator rod switching.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Combined with Figures 1 to 7 The present invention provides a lifting device with slideway adjustment, aiming to optimize the positioning and installation structure of the existing actuator rod switching.

[0035] Specifically, it includes a slider 1, a roller 2 and a locking mechanism 3;

[0036] The locking mechanism 3 includes a screw rod 31 and a moving block 32; the moving block 32 is arranged in the slide groove 11 on the slider 1; the inner end of the screw rod 31 is threadedly penetrated on the slider 1 and extends inwardly into the slide groove 11 to connect with the slider 1; the screw rod 31 drives the slider 1 to move forward and backward in the slide groove 11, so as to realize the clamping and positioning installation of the slider 1 and the linear guide rail 41 on the lifting device 4;

[0037] The roller 2 is positioned on one side of the slider 1 , and an actuator rod 6 is positioned on the other side; the roller 2 is engaged with the linear guide rail 41 to achieve the lifting and lowering of the actuator rod 6 by sliding the slider 1 up and down.

[0038] The present application sets a slider, a roller and a locking mechanism, and clamps the roller with the slide of the linear guide slide. At the same time, the locking mechanism is clamped to achieve the limitation of the height direction of the slider, thereby realizing the positioning and installation of the actuator rod; when disassembly is required, it is only necessary to loosen the locking mechanism and then slide the slider upward out of the slide in the height direction. The operation is convenient and quick.

[0039] It should be noted that the device does not require the installation of structures such as clamps and bolts, and does not require the installation and disassembly of clamps and bolts. A single person can perform the positioning and installation operations, thereby protecting the safety of the staff and greatly improving work efficiency.

[0040] Furthermore, the moving block 32 and the roller 2 are provided on the front of the slider 1, and an actuator rod 6 is fixedly provided on the back; the linear guide rail 41 is vertically arranged along the height direction.

[0041] Furthermore, the linear guide rail slideway 41 is a groove structure with a "convex"-shaped cross section.

[0042] Furthermore, the slider 1 is a block structure.

[0043] Specifically, the slider 1 is a rectangular parallelepiped with a length of 13 cm, a width of 46 mm, and a height of 12 mm. The slider 1 is made of high-strength aluminum alloy material. A pulley and a steel block are fixed on one side, and the other side is fixed with a fixing screw to fix the actuator rod of the remote control release device of the high-voltage circuit breaker. The actuator rod is moved on the linear guide channel to achieve height adjustment of the actuator rod.

[0044] Furthermore, baffles 5 are provided at both ends of the slider 1; the baffles 5 are fixedly installed at both ends of the slider 1; the baffles 5 match the cross-sectional dimensions of the linear guide rail slideway 41, and are used to achieve isolation when the slider 1 is positioned and installed in the slideway.

[0045] Specifically, the baffle 5 is made of rubber material to prevent the edge of the slider 1 from hurting the operator. When the slider 1 slides on the linear guide rail 41, the baffle 5 prevents foreign objects from falling into the track, causing the roller 2 to get stuck and the slider 1 to be unable to move.

[0046] Furthermore, the moving block 32 is a square structure; the slide groove 11 is an upwardly open long strip groove structure, and the size of the slide groove 11 is slightly larger than the size of the moving block 32; the slide groove 11 is arranged at the middle position above the roller 2; the position of the moving block 32 and the shaft core 42 is controlled by the screw 31 and the spring 33, and the position of the fixed slider 1 is squeezed by the moving block 32 and the shaft core 42.

[0047] Specifically, the length of the slide groove 11 is greater than the width of the roller 2. The moving block 32 is a traditional rectangular design with a length of 15 mm, a width of 9 mm, and a height of 22 mm. The moving block 32 can move in the linear guide slide 41. The moving block 32 is made of stainless steel material. The moving block 32 protrudes from the slider 1 and is used to achieve the positioning setting of the slider 1 by pressing the moving block 32 clamped in the linear guide slide 41 to one side.

[0048] Furthermore, a handle 34 is connected to the axial outer end of the screw rod 31 .

[0049] Furthermore, a spring 33 is provided; the spring 33 is sleeved on the screw rod 31, and the two ends of the spring 33 use the handle 34 and the slider 1 as spring seats respectively.

[0050] In one embodiment, in combination with Figure 7 The outer end of the screw rod 31 is provided with a thread which is threadably connected to the slider 1, and the inner end is provided with a smooth rod which is positioned and connected to the slider 1; by rotating the screw rod 31, the screw rod 31 moves back and forth on the slider 1, and the front end of the screw rod 31 is stuck in the accommodating groove of the moving block 32, and the moving block 32 can only move back and forth along the slide groove 11.

[0051] When the screw rod 31 is not threadedly connected to the slider, the moving block 32 can be directly pushed forward and backward manually by the spring 33, and the screw rod 31 can be automatically reset due to the elastic force of the spring 33 after letting go. The structure is reasonable and the operation is convenient and fast.

[0052] Furthermore, at least one roller 2 is provided on the slider 1; the roller 2 is a roller structure with a concave middle, and the concave part of the roller 2 is rolled by a double-axis core 42. There are four rollers 2 in total, and their sizes and materials are exactly the same, with a diameter of 24 mm and a height of 13 mm.

[0053] Preferably, the four rollers 2 are arranged in sequence from left to right, the first and third rollers 2 slide on the left axis, and the second and fourth rollers 2 slide on the right axis, so that the friction resistance is small, the sliding is smoother and more even, and the operation is more convenient and quick for the operator.

[0054] It should be noted that the entire slider 1 can move up and down on the slideway by inserting the front protruding head of the roller 2 into the linear guideway 41 and sequentially arranging the rollers 2 along the length direction of the slider.

[0055] Furthermore, the linear guide rail slide 41 is fixed to one side of the telescopic rod of the remote control release device of the high-voltage circuit breaker. The guide rail is 81 cm long, 46 mm wide and 18.5 mm high. The guide rail is made of high-strength aluminum alloy material and is used for the up and down movement of the slider 1.

[0056] Specifically, the shaft core 42 adopts a double shaft core 42, which is fixed on the inner side of the linear guide rail 41. The shaft core 42 adopts a cylindrical design with a diameter of 8 mm and a length of 81 cm. The shaft core 42 is made of bearing steel material, has good hardness and wear resistance, and can make the roller 2 move smoothly.

[0057] When the present invention is implemented, the device can be used to operate the switch cabinet or mechanism box with different models of emergency trip buttons of high-voltage circuit breaker equipment in the substation. The linear guide slide is fixed to one side of the telescopic rod of the high-voltage circuit breaker remote control release device, and the actuator rod of the high-voltage circuit breaker remote control release device is fixed to one side of the slider. The slider is placed in the linear guide slide through a roller and locked by a locking mechanism. In this way, the device is assembled.

[0058] When working on site, place the above device in front of the switch cabinet or mechanism box of the high-voltage circuit breaker equipment that needs to be operated for emergency opening. The actual position of the emergency opening button of some high-voltage circuit breakers may be too low. This device tightens the screw to squeeze the steel block and the shaft core, generating friction to prevent the slider from moving, thereby fixing the actuator rod. When the height needs to be adjusted, loosen the screw, slide the roller on the double shaft core to adjust the position of the slider, and align the actuator rod with the emergency opening button before remote control operation can be performed.

[0059] It should be noted that every second counts in equipment accident handling, and reliable completion of equipment operation is indispensable to ensure the reliable operation of power grids and equipment. The device can flexibly and conveniently adjust the height of the actuator rod, saving equipment operation time, gaining valuable time for reliable emergency tripping of the circuit breaker, and increasing the reliability of the actuator rod and the guide rail, ensuring the reliable completion of the work, and effectively improving the safety and reliability of power grid operation. The present invention has a simple structure and is easy to disassemble and assemble. When idle, the device can be disassembled for easy storage and transportation, easy to carry and manage, and can be carried to the work site for assembly when in use. Moreover, the entire assembly process has a very small operating range, and the staff can complete it on the ground. The staff does not need to climb high, and the entire installation and use process is highly safe, time-saving, labor-saving, and very convenient. It protects the safety of the staff and greatly improves work efficiency, and is suitable for wide promotion.
