Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power transmission, and in particular relates to a spacer rod disassembly and assembly tool. Background Art
[0002] At present, spacers are widely used in overhead transmission lines on multi-split conductors. They are one of the important protective fittings for transmission lines. In order to ensure that the spacing between the split conductor bundles remains unchanged to meet the electrical performance and ensure the current-carrying capacity, spacers are installed at a certain distance in the span. However, the spacers installed on the split conductors are affected by the vibration of the running conductors for a long time, and may become loose or even damaged, which seriously threatens the safe operation of the transmission line. Therefore, it is necessary to regularly inspect and replace the spacers.
[0003] In the process of replacing or installing the spacer bars, disassembly and assembly tools are required. Most of the existing tools are ratchet-driven screw transmissions to generate clamping force, thereby removing or inserting pins. The process of installing or removing the spacer bars is time-consuming and labor-intensive. It usually takes about 20 minutes to install or remove a spacer bar, which is not only inefficient but also consumes a lot of physical energy for the operators. In overhead operations, the tools are easily lost and dropped during the repeated tightening and loosening of the bolts, posing certain safety hazards.
[0004] Therefore, we propose a spacer rod disassembly and assembly tool to solve the above technical problems. Utility Model Content
[0005] In order to solve the technical problems in the prior art that the spacer bar disassembly and assembly tool is time-consuming and labor-intensive and has potential safety hazards, the utility model provides a spacer bar disassembly and assembly tool.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A spacer rod disassembly and assembly tool comprises a handle and a clamping mechanism, wherein the clamping mechanism is installed at the end of the handle, the handle is slidably connected to a piston rod at one end of the clamping mechanism, and a clamping opening is formed between the clamping mechanism and the piston rod, a driving mechanism for driving the piston rod to extend and retract is provided inside the handle, a battery is detachably connected to the bottom of the handle, and the battery is electrically connected to the driving mechanism.
[0008] By adopting the above technical solution, when replacing the spacer bar, the part to be clamped of the spacer bar is placed in the clamping opening formed between the clamping mechanism and the piston rod, and the driving mechanism is used to control the piston rod to extend forward, and the clamping mechanism is used to produce a clamping force, thereby clamping the part to be clamped of the spacer bar until the spacer bar pin can be taken out, and then the pin is taken out, and then the piston rod is controlled to retract, and the spacer bar and a wire are disassembled. After that, the operation is repeated to remove all the pins, and the disassembly of a spacer bar is completed. The process of installing the spacer bar is similar to the disassembly process. In this way, when the spacer bar is disassembled and assembled using the spacer bar disassembly and assembly tool of the utility model, the piston rod is controlled to be extended and retracted by the driving mechanism instead of the manual disassembly and assembly process, which is more time-saving and labor-saving than traditional tools. It not only reduces the work intensity of the staff, but also improves the replacement efficiency of the spacer bar, solves the problems of cumbersome high-altitude operations, long operation time, and high labor intensity in the past, and effectively reduces the risks of high-altitude operations caused by long-term operations.
[0009] In a further technical solution, the driving mechanism includes a hydraulic component, which includes a hydraulic cylinder, a first piston and a second piston. The two ends of the hydraulic cylinder are respectively connected to the handle and the clamping mechanism. The first piston and the second piston are respectively slidably arranged on both sides inside the hydraulic cylinder. Hydraulic oil is provided between the first piston and the second piston. The piston rod extends into the hydraulic cylinder and is connected to the first piston. The rear of the second piston is connected to an electric driving component for controlling the second piston to slide back and forth in the hydraulic cylinder. The electric driving component is electrically connected to a battery.
[0010] By adopting the above technical solution, during the disassembly and assembly process of the spacer rod, the electric drive component is used to control the second piston to slide forward and squeeze the hydraulic oil, thereby driving the first piston to slide forward, so that the piston rod extends forward and cooperates with the clamping mechanism to generate a clamping force, thereby clamping the part to be clamped of the spacer rod, making it convenient to remove or insert the through pin. The electric drive method replaces the manual disassembly and assembly process, effectively solving the problem of time-consuming and labor-intensive installation or removal of the spacer rod in the prior art.
[0011] In a further technical solution, the hydraulic cylinder is provided with a cylinder sleeve on a sealing sleeve on one side through which the piston rod passes, the piston rod passes through and extends out of the cylinder sleeve and is slidably connected to the cylinder sleeve, and the clamping mechanism is connected to the cylinder sleeve.
[0012] By adopting the above technical solution, by sleeve-arranging the cylinder sleeve at the end of the hydraulic cylinder, the sealing effect of the hydraulic cylinder is improved, the probability of hydraulic oil leakage in the hydraulic cylinder is reduced, and it is convenient for use.
[0013] In a further technical solution, a compression spring is sleeved on the piston rod, one end of the compression spring is fixedly connected to the first piston, and the other end of the compression spring is fixedly connected to the cylinder sleeve.
[0014] By adopting the above technical solution and arranging a compression spring, during the process of controlling the retraction of the piston rod, the elastic potential energy of the compression spring can enable the piston rod to be reset, which is convenient for the next use.
[0015] In a further technical solution, the electric drive assembly includes a servo motor, a lead screw and a control switch, one end of the lead screw is fixedly connected to the output shaft of the servo motor, and the other end is threadedly connected to the second piston, the control switch and the battery are both electrically connected to the servo motor, and the control switch is installed on the outside of the handle.
[0016] By adopting the above technical scheme, the electric drive component cooperates with the servo motor, the lead screw and the control switch. The control switch turns on the servo motor, drives the lead screw to rotate, controls the second piston to slide forward in the hydraulic cylinder, squeezes the hydraulic oil to control the first piston to slide forward, and thus extends the piston rod forward. Through the cooperation of the electric drive component and the hydraulic component, the rotational motion of the lead screw is converted into linear motion, effectively clamping the part to be clamped of the spacer rod, thereby facilitating the disassembly and assembly of the spacer rod.
[0017] In a further technical solution, the clamping mechanism includes a C-type caliper, which is detachably connected to the handle and has a through hole at one end of the connection, and the piston rod is slidably arranged in the through hole.
[0018] By adopting the above technical solution, the C-type caliper is detachably connected to the handle, which not only facilitates disassembly and maintenance, but also allows replacement of different types of C-type calipers, which is conducive to the disassembly and assembly of different types of spacer bars.
[0019] In a further technical solution, the handle is provided with a plurality of clamping plates, each of which is provided with a fixing hole, the end of the C-type caliper is provided with a plurality of through holes matching the fixing holes, and the C-type caliper and the clamping plates are connected by bolts.
[0020] By adopting the above technical solution, the C-type caliper and the clamping plate are connected by bolts, that is, the C-type caliper and the handle are connected by bolts, which is convenient for disassembly and assembly and is conducive to use.
[0021] In a further technical solution, the end of the piston rod is threadedly connected to a hydraulic top block.
[0022] By adopting the above technical solution, the hydraulic top block can not only increase the contact area between the piston rod and the clamping part of the spacer bar, thereby improving the clamping stability during disassembly and assembly, but also adjust the effective stroke of the piston rod by replacing hydraulic top blocks of different thicknesses, thereby accurately controlling the clamping force on the spacer bar and improving the applicability and flexibility of the tool.
[0023] In a further technical solution, an anti-drop rope is connected to the handle.
[0024] By adopting the above technical solution, the anti-slip rope can prevent the tool from slipping out of the hand and falling, thereby reducing the safety hazard of high-altitude operations.
[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
