Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to a tightening device operating rod. Background Art

[0002] At present, in the process of laying out the power system, since the tensioner needs to be sent to the laying end before tightening the line, and then the tensioner is operated to tighten the line, most of the existing tensioners need the operator to push them directly outward with his hands when pushing them outward. During the tightening work, the tail end of the movable wire clamp is often short, and the operation and maintenance personnel need to stretch outward to a large extent. However, due to the limited arm span of the operator, it is often necessary to extend the pushing distance by adding rods such as wooden sticks.

[0003] However, the pull arm of the tensioner is movable and inconvenient to fix. If a rope is used to tie the rod and the tensioner arm together, after the tensioner is pushed to the right, the rope cannot be untied, causing the rod to interfere with the tensioning operation. Although some rods with retractable functions are available on the market, the connection with the tensioner is not firm and interference is easy to occur when the rod is retracted. Summary of the invention

[0004] The object of the present invention is to provide a tensioner operating rod, which can be firmly connected to the tensioner and is convenient and quick to retract the operating rod without affecting subsequent tensioning operations.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] The present invention discloses a tensioner operating rod, such as Figure 1 As shown, the operating rod includes a rod body 1, a connecting clamp 2, a locking mechanism 3, and an operating member 4. The rod body 1 of the operating rod is telescopically arranged to extend the distance of the externally pushed tensioner; the connecting clamp 2 is arranged at one end of the rod body 1 for cooperating with the tensioner; the locking mechanism 3 is arranged on the connecting clamp 2, and the locking mechanism 3 can lock the connecting clamp 2 so that the connecting clamp 2 and the tensioner remain in cooperation, thereby increasing the stability of the cooperation between the connecting clamp 2 and the tensioner; one end of the operating member 4 is connected to the locking mechanism 3, and the other end passes through the rod body 1, and the locking mechanism 3 is driven to unlock by operating the end of the operating member 4 passing through the rod body 1, so that the connecting clamp 2 can be separated from the tensioner. It can be understood that by setting a telescopic rod body 1, the distance of the externally pushed tensioner can be extended as much as possible, so that the number of rod replacement operations can be reduced, and the telescopic rod body 1 can be easy to carry when not in use. The connecting chuck 2 can cooperate with the tensioner and will not fall off when the tensioner is pushed. The locking mechanism 3 can further ensure the stability of the cooperation between the connecting chuck 2 and the tensioner. The operating member 4 can be a pull rope, one end of which is connected to the locking mechanism 3 and the other end passes through the inside of the rod body 1. By pulling the operating member 4 through one end of the rod body 1, the connecting chuck 2 can be opened conveniently and quickly, so that the operating rod is separated from the tensioner, and the subsequent tensioning work of the tensioner is not affected.

[0030] In some embodiments, Figure 2As shown, the connecting chuck 2 includes a fixed chuck 21 and a movable chuck 22. The fixed chuck 21 is fixedly arranged on the rod body 1, and the movable chuck 22 is pivotally connected to the fixed chuck 21, and the movable chuck 22 can rotate around the pivot axis. It can be understood that the movable chuck 22 and the fixed chuck 21 work together, and can be directly connected to the tensioner arm by clamping, or the movable chuck 22 and the fixed chuck 21 define a receiving space for accommodating the tensioner connecting arm ring, and connect to the tensioner by a buckle, which can adapt to different connection methods of existing tensioners of different models without changing the structure of the tensioner itself.

[0031] In some embodiments, a first elastic member 5 is provided between the movable clamp 22 and the fixed clamp 21, so that the connecting clamp 2 has a tendency to open. It is understandable that the first elastic member 5 can be a torsion spring, which is sleeved on the pivot shaft, and at least one abutment column is provided on the fixed clamp 21 and the movable clamp 22, respectively abutting against two abutment ends of the torsion spring.

[0032] In some embodiments, two fixed clamps 21 are provided, the two fixed clamps 21 are arranged in parallel and at intervals, and the movable clamp 22 and the locking mechanism 3 are arranged between the two fixed clamps 21. Figure 3 As shown, the fixed chuck 21 includes a plug-in portion 211, a joint portion and a connecting portion 213. The plug-in portion 211 is plugged into the rod body 1 and fixedly connected to the rod body 1, the chuck portion 212 cooperates with the movable chuck 22 together with the tensioner, and the connecting portion 213 is arranged between the plug-in portion 211 and the chuck portion 212, and is used to support the movable chuck 22 and the locking mechanism 3. It can be understood that the above-mentioned arrangement can be conveniently and quickly assembled, and can avoid the shear force biased to one side in the clamping scene, and avoid the tensioner having a tendency to rotate to one side. In other embodiments, the fixed chuck 21 can also be set as one, the thickness of the connecting portion 213 is set to be greater than the plug-in portion 211 and the chuck portion 212, and the connecting portion 213 is hollow, and the locking mechanism 3 and the movable chuck 22 are arranged in the connecting portion 213.

[0033] In some embodiments, Figure 2 As shown, the locking mechanism 3 includes a locking rack 31 and a locking member 32. The locking rack 31 is fixedly connected to the movable chuck 22 and can rotate together with the movable chuck 22. The locking member 32 can be movably arranged on the fixed chuck 21; wherein, a ratchet is arranged on the locking rack 31, and a pawl is arranged at one end of the locking member 32, and the pawl on the locking member 32 is engaged with the ratchet of the locking rack 31 to fix the movable chuck 22. It can be understood that when the operating member 4 is not pulled, the chuck portion 212 of the fixed chuck 21 and the movable chuck 22 can only move unidirectionally toward one end close to each other to achieve locking, so as to prevent the operating rod from falling off when cooperating with the tensioner, thereby affecting the safety of equipment and personnel.

[0034] In some embodiments, Figure 4 As shown, the locking member 32 is provided with a guide groove 321. At least two guide posts are provided on the fixing clamp 21, and the at least two guide posts cooperate with the guide groove 321 to achieve limiting and guiding, so that the locking member 32 can slide along the length direction of the rod body 1. Figure 2 As shown, a second elastic member 6 is provided between the locking member 32 and the fixed chuck 21, so that the locking member 32 has a tendency to move toward the locking rack 31. It can be understood that the second elastic member 6 is set as a spring, the locking member 32 is a strip structure, and two springs are provided, which are respectively located on both sides of the width direction of the locking member 32, one end of the spring is connected to the locking member 32, and the other end is connected to the connecting portion 213 of the fixed chuck 21, so that the locking member 32 has a tendency to move toward the locking rack 31. For example, the initial state of the spring is set to a stretched state, and the locking member 32 is meshed with the locking rack 31 in the locked state. When unlocking, the operating member 4 is pulled to overcome the spring tension and continue to stretch the spring, so that the locking member 32 is separated from the locking rack 31, and the movable chuck 22 automatically rotates under the action of the first elastic member 5, so that the connection chuck 2 is separated from the tensioner.

[0035] In an alternative embodiment, the locking member 32 is rotatably connected to the fixing clamp 21, so that the end of the locking member 32 provided with the pawl can rotate, and a second elastic member 6 is provided between the locking member 32 and the fixing clamp 21, so that the locking member 32 has a tendency to rotate toward the locking rack 31. It can be understood that the second elastic member 6 is configured as a spring or a torsion spring, which is disposed between the locking member 32 and the fixing clamp 21, so that the locking member 32 has a tendency to move toward the locking rack 31. It can be understood that the second elastic member 6 enables the locking member 32 to engage with the locking rack 31 in the locked state. Due to the distance setting between the locking member 32 and the locking rack 31, when continuing to rotate in one direction, it will be blocked and cannot continue to rotate in that direction to achieve locking. When unlocking, the operating member 4 is pulled, and the operating member 4 pulls the locking member 32 to rotate in the opposite direction to disengage the two, thereby separating the locking member 32 from the locking rack 31, and the movable clamp 22 automatically rotates under the action of the first elastic member 5 to achieve the separation of the connecting clamp 2 and the tensioner.

[0036] In some embodiments, Figure 5As shown, the locking rack 31 includes a fixed portion 311 and a rack portion 312. The fixed portion 311 is used to connect with the movable chuck 22; the rack portion 312 is arranged in an arc shape, and the ratchet is arranged on the rack portion 312, and the rack portion 312 is used to cooperate with the locking member 32 to achieve locking. One end of the rack portion 312 is fixedly connected to the fixed portion 311, and the two can be integrally formed, which is not limited here. It can be understood that the curvature of the rack portion 312 is adapted to the rotation curvature of the position where it is installed on the movable chuck 22, so as to prevent the movable chuck 22 from disengaging or interfering with the rack portion 312 and the locking member 32 when rotating.

[0037] In some embodiments, the rod body 1 is composed of at least two pipes with different diameters, at least two pipes are nested and can slide relative to each other along their axial direction. In any two adjacent pipes, the inner diameter of the pipe located outside is larger than the outer diameter of the pipe located inside. Therefore, in the two adjacent pipes, the pipe with a smaller outer diameter can be retracted into the pipe with a larger inner diameter, and when the rod body 1 needs to be stretched, the pipe with a smaller outer diameter can be pulled out from the pipe with a larger inner diameter. A constriction is provided at one end of the pipe with a larger inner diameter and serves as the stretching end of the pipe with a smaller outer diameter. The end of the pipe with a smaller outer diameter away from the constriction is expanded, but the overall diameter is still smaller than the inner diameter of the pipe with a larger inner diameter. Therefore, when the pipe is stretched to a certain position, it will not automatically retract under the action of the friction between the pipes, and the position of the pipe can be fixed, and the two adjacent pipes can be prevented from separating from the stretching end. In other embodiments, a clamping portion is provided at the end of each pipe, and the setting of the clamping portion can prevent the pipe with a smaller outer diameter from detaching from the pipe with a larger inner diameter when two adjacent pipes are stretched. It can be understood that the operating member 4 passes through and out of the innermost layer of pipe fittings to avoid affecting the expansion and contraction between the pipe fittings.

[0038] In order to make the pipes more firmly fixed, Figure 1 As shown, the tensioner operating rod also includes at least one locking member 7, which can lock the pipe of the rod body 1 to fix the telescopic length of the rod body 1, and can also fix the length of the rod body 1 at any position within the telescopic length range of the rod body 1 according to actual required length.

[0039] To facilitate understanding of the present invention, an example is given to illustrate the operation method in one embodiment of the present invention. When the tensioner operating rod disclosed in the present invention cooperates with the tensioner, after the connecting clamp 2 is inserted into the arm of the tensioner, the movable clamp 22 is pressed, and the movable clamp 22 is tightened. Restricted by the locking mechanism 3, under the action of the locking rack 31 and the locking member 32, the connecting clamp 2 will not open. At this time, the pipe fitting of the rod body 1 can be operated to be retracted and fixed to push the tensioner. When the length is not enough, the pipe body can be extended again and fixed, and the tensioner can be pushed again.

[0040] When the tensioner is pushed to a suitable position, the operating member 4, that is, the pull rope, which passes through the inside of the rod body 1 is pulled to drive the locking member 32 of the locking mechanism 3 to move toward the rod body 1. At this time, under the action of the torsion spring, the movable clamp 22 will open, and the entire operating rod can be separated from the tensioner.

[0041] The operating rod of the present invention can not only extend the distance of the outward push tensioner, but also ensure that the connection between the two is stable and will not fall off through the locking mechanism 3 when cooperating with the tensioner. When it is necessary to disengage from the tensioner, only the operating member 4 needs to be pulled to automatically open the movable clamp 22, so that the operating rod and the tensioner are disengaged. The operation is convenient and quick, and does not affect the subsequent work of the tensioner.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
