Description

Technical Field

[0001] The invention relates to the technical field of live working, in particular to a working clamp that is convenient for setting up a drainage line. Background Art

[0002] In traditional power line repair operations, operators usually use power outages or live operations to maintain the lines, and use insulating rods and wire clamps to operate and fix the wires. During this period, the wire clamp needs to be loosened first, sent to the corresponding position, and then the drainage wire is inserted, and finally the wire clamp is firmly fixed with a screw. In order to ensure that the wire clamp has a certain contraction force during the insertion of the drainage wire and does not loosen and slip, the existing conventional method is to wrap tape on one side of the wire clamp.

[0003] The traditional tape fixing method has poor stability. When the line is more complicated, it takes a lot of force to send the drainage line to the ignition position. The tape is easily lost due to the imbalance of force during the process. This not only increases the workload of re-fixing, but also in high-altitude operations, the loss of the wire clamp may cause serious risks of falling objects from high altitudes, threatening the safety of ground personnel and operators. The instability of the tape requires operators to use greater force and more time to fix the wire clamp, especially under complex line conditions.

[0004] Therefore, a work clamp is needed that is easy to operate even if the worker is wearing bulky insulating gloves, has a higher efficiency and is more secure in fixing the wire clamp, and will not loosen even if the guide wire is forcefully inserted in complex situations to meet the needs of the existing live working environment.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Example 1

[0034] Reference Figures 1 to 5 , this embodiment provides a work fixture that is convenient for setting up drainage lines.

[0035] The clamping mechanism 100 is used to clamp the conductor and pass the drainage line. The left space of the clamping mechanism 100 is used to directly clamp and fix the overhead conductor, and the drainage line passes through the right space of the clamping mechanism 100. The threaded rod 102 is used to tighten the cable after adjustment to achieve the final clamping effect. The constriction mechanism 200 is used to achieve a constriction effect on the right side of the clamping mechanism 100, ensuring that when the threaded rod 102 is not tightened, it can have a certain constriction force to prevent the clamping mechanism 100 from being squeezed open and falling off when the drainage line is passed around.

[0036] Two receiving holes 201 are provided on the right side of the clip 101. The receiving holes 201 are located at the upper and lower parts of the clip 101. One end of the receiving hole 201 is closed and the other end is open, which is convenient for operation. A sleeve 202 is slidably provided on the inner wall of the receiving hole 201. The sleeve 202 can be inserted along the receiving hole 201 or placed separately from the clip 101. Each receiving hole 201 corresponds to a sleeve 202. A control rod 203 is rotatably provided on the inner wall of the sleeve 202. An opening is fixedly provided on the outer wall of the sleeve 202. When the control rod 203 rotates along the inner wall of the sleeve 202, the outer wall of the control rod 203 can also contact the outside through the opening.

[0037] One end of the constraint arc piece 204 is fixedly arranged on the outer wall of the control rod 203, and the two control rods 203 unfold the constraint arc piece 204 and fit the right side of the clamp 101. The adjustment mechanism 300 is used to control the unfolding state of the constraint arc piece 204. The unfolding state of the constraint arc piece 204 can be adjusted by rotating the control rod 203 to ensure that the constraint force of the constraint arc piece 204 is relatively small at this time, which is convenient for the staff to install. The material of the constraint arc piece 204 can be rubber or aluminum sheet with good ductility.

[0038] The inner wall of the sleeve 202 is fixed with a limit ring 301, which can constrain the rotation of the control rod 203. The toggle rod 302 is located at the tail of the control rod 203. When the control rod 203 starts to rotate, the toggle rod 302 will also rotate with the control rod 203, thereby contacting the limit ring 301. The front end of the control rod 203 is connected to the inner wall of the sleeve 202 through the torsion spring 203b. In the default state, the staff can manually rotate the control rod 203 so that the control rod 203 overcomes the elastic force of the torsion spring 203b to rotate, thereby adjusting the tension of the constraining arc piece 204, which is convenient for the staff to install the sleeve 202 into the storage hole 201.

[0039] The limit ring 301 can play a one-way locking role on the toggle rod 302, preventing the toggle rod 302 from following the control rod 203 to reset under the action of the torsion spring 203b, and the staff does not need to apply force for a long time to keep the constraint arc piece 204 in an open state. When the sleeve 202 is inserted along the storage hole 201, the one-way locking effect of the limit ring 301 on the toggle rod 302 is released, and the control rod 203 rotates and resets under the action of the torsion spring 203b, thereby driving the constraint arc piece 204 to tighten. At this time, the constraint arc piece 204 can achieve the maximum convergence effect on the right part of the clamping mechanism 100.

[0040] Example 2

[0041] Reference Figures 1 to 8 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a receiving opening 205 is provided on the right side of the clip 101, and two receiving openings 205 are provided, each receiving opening 205 corresponds to a receiving hole 201, and the receiving opening 205 is located on the oblique side of the receiving hole 201, and the receiving opening 205 and the receiving hole 201 are connected through. A rotation groove 202a is provided through the surface of the sleeve 202, and the rotation groove 202a corresponds to the control rod 203. When the control rod 203 rotates along the inner wall of the sleeve 202, the outer wall of the control rod 203 can also contact the outside world through the rotation groove 202a. A mounting protrusion 203a is fixedly provided on the outer wall of the control rod 203, and the mounting protrusion 203a passes through the rotation groove 202a and is located in the receiving opening 205. When the mounting protrusion 203a rotates following the control rod 203, the movable range of the mounting protrusion 203a is actually limited within the rotating groove 202a. A slot 203a-1 is fixedly provided on the top of the mounting protrusion 203a, and one side of the constraining arc piece 204 is inserted into the slot 203a-1. The size of the slot 203a-1 itself is consistent with the size of one side of the constraining arc piece 204. Friction can provide a basic limitation for the fixation of the constraining arc piece 204, and it is also convenient for the staff to remove the constraining arc piece 204 separately for debugging and maintenance.

[0042] A torsion spring 203b is fixedly installed on the top of the control rod 203, and the side wall of the torsion spring 203b is fixedly connected to the inner wall of the sleeve 202. A rotating handle 203c is set at the other end of the torsion spring 203b, and the rotating handle 203c itself is connected to the control rod 203. By operating the rotating handle 203c, the control rod 203 can be driven to rotate by the force of the torsion spring 203b. In the default state, the control rod 203 is acted upon by the torsion spring 203b, driving the constraint arc piece 204 to play a tightening role. An extension protrusion 301a is fixedly set on the outer wall of the limit ring 301, and the limit ring 301 is fixedly connected to the inner wall of the sleeve 202 through the extension protrusion 301a.

[0043] A torsion bar 301b is provided on one side of the limiting ring 301. The torsion bar 301b itself is torsionally connected to the side wall of the limiting ring 301. A toggle end 301b-1 is also fixedly sleeved on the outer wall of the torsion bar 301b. The toggle end 301b-1 can rotate following the rotation of the torsion bar 301b. A matching protrusion 302a is fixedly provided on the outer wall of the toggle bar 302. When the toggle bar 302 rotates following the control rod 203, the matching protrusion 302a will also rotate and the matching protrusion 302a will contact the toggle end 301b-1, pushing the toggle end 301b-1 away. The toggle end 301b-1 will then return to its original position under the effect of the torsion connection between the torsion bar 301b itself and the side wall of the limiting ring 301.

[0044] A sliding hole 301c is fixedly set on the other side of the toggle end 301b-1, and a locking block 301c-1 is slidably set in the sliding hole 301c. A spring 301c-2 is fixedly set at the other end of the locking block 301c-1, and the other end of the spring 301c-2 is fixedly connected to the sliding hole 301c. In the default state, the locking block 301c-1 is in a raised state and can prevent the toggle end 301b-1 from reversing. Therefore, even if the mating protrusion 302a contacts the toggle end 301b-1 and pushes the toggle end 301b-1 away, the subsequent reset of the toggle end 301b-1 will be blocked by the locking block 301c-1 and cannot reverse. At this time, even if the staff lets go and no longer applies force to the torsion spring 203b, the reverse force of the torsion spring 203b cannot drive the toggle end 301b-1 to rotate, and the toggle rod 302 is one-way locked by the limit ring 301.

[0045] Example 3

[0046] Reference Figures 1 to 9 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0047] An adjusting plug 201a is fixedly arranged at the end of the receiving hole 201, and the adjusting plug 201a faces the sleeve 202. An adjusting hole 202b is fixedly opened at the tail of the sleeve 202. The front diameter of the adjusting plug 201a matches the diameter of the adjusting hole 202b. When the sleeve 202 enters the receiving hole 201 in a straight line, the inner wall of the sleeve 202 will contact the adjusting plug 201a, and then the adjusting plug 201a can enter the inner wall of the sleeve 202 and slide against the inner wall of the sleeve 202 to adjust the air pressure in the sleeve 202. As the sleeve 202 gradually extends into the receiving hole 201, the air pressure applied to the limit ring 301 also gradually increases, and the air pressure pushes the locking block 301c-1 to overcome the spring 301c-2 and retract.

[0048] After the retraction, the locking block 301c-1 can no longer block the toggle end 301b-1, so under the action of the torsion spring 203b, the protrusion 302a follows the toggle rod 302 to push the toggle end 301b-1 back to the initial position, and the control rod 203 rotates and resets under the action of the torsion spring 203b, thereby driving the constraint arc piece 204 to tighten. At this time, the constraint arc piece 204 can achieve the maximum convergence effect on the right part of the clamping mechanism 100. The control rod 203 is also fixedly provided with an air guide hole 303 on one side facing the adjustment hole 202b, and the two sides of the air guide hole 303 are fixedly extended with conductive channels 303a, and the two conductive channels 303a are both located on the inner wall of the control rod 203.

[0049] As the sleeve 202 gradually extends along the receiving hole 201, the air pressure applied to the air guide hole 303 is also gradually increased, and the gas enters the conduction channel 303a. The two sides of the card slot 203a-1 are also provided with a receiving cavity 304, and an expansion member 304a is arranged in the receiving cavity 304. The expansion member 304a itself is connected with the conduction channel 303a. The gas enters the conduction channel 303a to drive the expansion member 304a to become larger, thereby compressing one side of the constraint arc piece 204, which plays a better fastening role in the installation of the constraint arc piece 204, and prevents the constraint arc piece 204 from loosening due to other unstable factors during the high-altitude operation, which brings inconvenience to the operation of the clip 101.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
