Description

Technical Field

[0001] The invention relates to the technical field of electric power fitting installation, and in particular to a linear multi-nut electric power fitting installation tool and an installation method. Background Art

[0002] Some power fittings are usually installed through multiple nuts, such as parallel groove wire clamps, piercing wire clamps, tension wire clamps, grounding rings, multi-bolt shock-absorbing hammers, steel strand iron accessories and insulator mounting seats. They are all installed through multiple linearly arranged nuts and bolts, and multiple bolts need to be screwed in sequence during installation or removal.

[0003] The patent with the announcement number CN114976805B discloses an insulating rod type electric adjustable parallel groove wire clamp installation tool, and its wire clamp fixing mechanism includes a housing, and the housing is rotatably connected with an operating gear. A limit groove is arranged on the upper side of the operating gear, and the limit groove and the nut are adapted and used to embed the nut, and the nut can be set as a hexagonal nut. The operating gear is connected to an electric wrench. Specifically, the operating gear is connected to the output rod of the electric wrench, so that the electric wrench can drive the operating gear to rotate. The number of operating gears is three, and the operating gears include a first operating gear, a second operating gear and a third operating gear. The first operating gear, the second operating gear and the third operating gear are arranged in sequence along a straight line. The first operating gear and the second operating gear are driven by a first transmission gear, and the second operating gear and the third operating gear are driven by a second transmission gear. The first transmission gear and the second transmission gear are both rotatably connected to the base, and the first transmission gear is connected to the electric wrench. Specifically, the upper end of the output rod of the electric wrench is connected to the first transmission gear. Through the above arrangement, when the output rod of the electric wrench rotates, under the action of the first transmission gear and the second transmission gear, the three operating gears rotate simultaneously. Then turn the handle, the active gear drives the driven gear to rotate, the driven gear drives the operating rod to rotate, the electric wrench rotates, drives the operating gear to rotate, the nut rotates, drives the bolt to rotate, the upper clamp block and the lower clamp block move together and clamp the wires, until the nut is disconnected from the bolt under the action of the operating gear.

[0004] In the above patent, multiple synchronously rotating operating gears are used to simultaneously tighten each nut. Although the operation is convenient, it is only applicable to tightening multiple torque nuts, and cannot be applied to tightening multiple non-torque nuts (ordinary nuts). When multiple non-torque nuts need to be tightened, since the number of rotations required to tighten each nut is different in most cases, although the above patent tightens each nut, it cannot guarantee that all nuts have been tightened, resulting in an unstable installation. Summary of the invention

[0005] The object of the present invention is to provide a linear multi-nut electric power fitting installation tool and an installation method to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a linear multi-nut electric hardware installation tool, comprising an insulating rod, a tool body and an electric wrench, wherein the tool body is rotatably connected to one end of the insulating rod along the Y-axis; a track is elastically slidably connected to the tool body along the Y-axis through a spring, and the electric wrench is slidably connected to the track along the Z-axis so as to be able to sequentially connect with each nut of the electric hardware; a sliding part is slidably connected to the handle of the insulating rod along the Y-axis, and the track is fixedly connected to a connecting part through a bracket, and the other end of the connecting part passes through the inside of the insulating rod and is fixedly connected to the sliding part; a sliding sleeve is provided on the insulating rod along the Y-axis sliding sleeve, and a telescopic rod is hinged on the sliding sleeve, and the other end of the telescopic rod is hinged to the housing of the electric wrench.

[0009] Furthermore, the sliding part includes a wristband and a radial rod. The wristband is movably sleeved on the circumferential side of the insulating rod. A sliding groove is axially provided on the insulating rod. One end of the radial rod is connected to the wristband, and the other end passes through the sliding groove to the inside of the insulating rod and is fixedly connected to the connecting part.

[0010] Furthermore, a limiting piece corresponding to each nut is provided between the sliding hoop and the track.

[0011] Furthermore, the limiting member includes a ball and a plurality of ball grooves provided on the track, each ball groove corresponds one by one to each nut to be tightened of the electrical hardware, and the ball is elastically arranged on the sliding hoop through a compression spring, and the ball can be engaged in each ball groove in sequence during the movement of the electric wrench along the track.

[0014] Compared with the prior art, the present invention can make the sleeve of the electric wrench detach from the tightened nuts and bolts by pulling the sliding part (hand ring) near the handle, and the sleeve of the electric wrench can be switched to align with the next nut to be tightened in sequence by rotating the insulating rod without loosening the sliding part. After loosening the sliding part, the elastic force of the spring can make the sleeve be set to the aligned row of nuts to be tightened, so that each linearly arranged nut (whether torque nut or non-torque nut) can be tightened or loosened in sequence. The installation and disassembly operations of the power fittings are very simple and convenient, and only the tool body needs to be positioned once.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-Figure 10A linear multi-nut electric hardware installation tool provided by an embodiment of the present invention comprises an insulating rod 1, a tool body 2 and an electric wrench 3, wherein the tool body 2 is rotatably connected to one end of the insulating rod 1 along the Y axis; the tool body 2 is slidably connected to a bracket 10 along the Y axis, and a track 14 and a connecting piece 6 are fixedly connected to the bracket 10, a spring 11 is sleeved on the bracket 10, one end of the spring 11 abuts the tool body 2, and the other end is connected to the bracket 10, and the elastic force of the spring 11 acts on the electric wrench 3 in the direction of approaching the nut to be tightened, that is, when the spring 11 releases the elastic force, the electric wrench 3 is driven to move along the Y axis close to the nut to be tightened of the electric hardware, so that the track 14 is elastically slidably connected to the tool body 2 along the Y axis through the spring 11 and the bracket 10, a sliding hoop 13 is fixedly connected to the housing of the electric wrench 3, and the sliding hoop 13 is slidably sleeved on the track 14 along the Z axis, so that the electric wrench 3 can slide along the track 14, and the electric wrench 3 can sequentially connect with each nut of the electric hardware when sliding on the track 14.

[0030] A sliding sleeve 7 is provided on the insulating rod 1 along the Y-axis sliding sleeve, and a telescopic rod 8 is hinged on the sliding sleeve 7. The other end of the telescopic rod 8 is hinged to the housing of the electric wrench 3. The telescopic rod 8 does not need to have damping, and the telescopic rod 8 can be a double-section telescopic rod or a three-section telescopic rod, depending on the actual configuration requirements.

[0031] A sliding part is connected to the handle of the insulating rod 1 along the Y-axis, and the track 14 is fixedly connected to the connecting part 6 through the bracket 10. The other end of the connecting part 6 passes through the inside of the insulating rod 1 and is fixedly connected to the sliding part. The sliding part specifically includes a wristband 4 and a radial rod 5. The wristband 4 is movably sleeved on the circumferential side of the insulating rod 1. A slide groove 12 is axially provided on the insulating rod 1 near the handle. One end of the radial rod 5 is connected to the wristband 4, and the other end passes through the slide groove 12 to the inside of the insulating rod 1 and is fixedly connected to the connecting part 6. The electric wrench 3 can be driven to move on the Y-axis by turning the wristband 4.

[0032] Among them, the Y axis and the Z axis are two mutually perpendicular directions in space.

[0033] The present embodiment also provides an installation method for a linear multi-nut electric hardware installation tool, and the specific operation of the installation method is as follows: first, the tool body 2 is clamped with the electric hardware; then, the sleeve 31 of the electric wrench 3 is inserted into one of the nuts to be tightened on the electric hardware, and the elastic force of the spring 11 causes the sleeve 31 to press against the nut to be tightened; the electric wrench 3 is started, and the sleeve 31 begins to tighten the nut to be tightened, so that the nut to be tightened is locked or loosened (if tightened, one nut has been tightened, and the electric hardware has been installed on the installation object, and the tool body 2 will not rotate when the insulating rod 1 is rotated subsequently; if loosened, the tool body 2 will not rotate when the insulating rod 1 is rotated subsequently; if loosened, the tool body 2 will not rotate when the insulating rod 1 is rotated subsequently; if loosened, the tool body 2 will not rotate when the insulating rod 1 is rotated subsequently. There are other nuts that have not been loosened, the power fittings are still fixed on the installation object, and the tool body 2 will not rotate when the insulating rod 1 is rotated subsequently); next, pull the hand ring 4 to disengage the sleeve 31 of the electric wrench 3 from the nut that has been screwed and the corresponding nut; then, while keeping the hand ring 4 pulled, rotate the insulating rod 1, and move the electric wrench 3 along the track 14 through the telescopic rod 8 to align the sleeve 31 with the next nut to be screwed, then loosen the hand ring 4, and the elastic force of the spring 11 moves the sleeve 31 to the aligned nut, and then start the electric wrench 3 to screw the aligned nut, and in this way, all the nuts can be screwed in turn.

[0034] In the above technical scheme, the sleeve 31 of the electric wrench 3 can be separated from the tightened nuts and bolts by pulling the sliding member (hand ring 4) near the handle, and the sleeve 31 of the electric wrench 3 can be switched to align with the next nut to be tightened in sequence by rotating the insulating rod 1 without loosening the sliding member. After loosening the sliding member, the elastic force of the spring 11 can make the sleeve 31 be sleeved on the aligned row of nuts to be tightened, so that each linearly arranged nut (whether torque nut or non-torque nut) can be tightened or loosened in sequence, and the installation and disassembly operations of the electric hardware are very simple and convenient, and only the tool body 2 needs to be positioned once. Especially when working at high altitude, the operator can operate with one hand, which is convenient for the other hand to grasp and stabilize the guardrail, pole tower and other components, thereby improving the safety of high altitude work. The present invention is not only applicable to the installation of linear multi-nut electric hardware, but also applicable to the disassembly of linear multi-nut electric hardware. The disassembly steps are the same as the installation steps, and the only difference is that the rotation direction of the sleeve 31 of the electric wrench 3 is changed.

[0035] The present invention also provides a preferred technical solution, wherein a limit piece corresponding to each nut is provided between the sliding hoop 13 and the track 14, and during the process of rotating the insulating rod 1 to switch the position of the electric wrench 3, the limit piece can help the limit wrench to align the nut more accurately.

[0036] In one embodiment, the stopper includes a spherical ball 91 and a plurality of ball grooves 93 provided on the track 14, each ball groove 93 corresponds to each nut to be tightened of the electric hardware, a shrinking groove is provided on the sliding hoop 13, the diameter of the inside of the shrinking groove matches the diameter of the ball 91, the diameter of the mouth of the shrinking groove is smaller than the diameter of the ball 91, the mouth of the shrinking groove is close to the surface of the track 14, the ball 91 is movably arranged in the shrinking groove on the sliding hoop 13, a compression spring 92 is arranged in the shrinking groove, one end of the compression spring 92 abuts against the bottom of the shrinking groove, and the other end abuts against the ball 91, and the elastic force of the compression spring 92 pushes the ball 91 against the mouth of the shrinking groove. During the movement of the electric wrench 3 along the track 14, the ball 91 can be snapped into each ball groove 93 in turn.

[0037] When the insulating rod 1 is rotated to drive the electric wrench 3 to move along the track 14: when the ball 91 is not aligned with the ball groove 93, the ball 91 is squeezed into the inside of the shrinkage groove by the track 14, and the compression spring 92 is further compressed, and the ball 91 rolls relative to the track 14. Due to the small rolling friction, the wear between the ball 91 and the track 14 is also very small; when the ball 91 is aligned with the ball groove 93, the elastic force of the compression spring 92 will immediately squeeze the ball 91 into the ball groove 93. At this time, the hand rotating the insulating rod 1 will have a clear feeling, and if the insulating rod 1 continues to be rotated, since the ball 91 wants to overcome the pressure of the compression spring 92 and roll out of the ball groove 93, the resistance of the rotating insulating rod 1 will increase significantly, and the operator can further perceive it. Even if the operator does not rely on vision, he can judge by touch that the electric wrench 3 has been accurately aligned with the next nut to be tightened, thereby stopping the rotation of the insulating rod 1.

[0038] In another embodiment, the limiting member includes a ball 91 and a plurality of protrusions 94. The ball 91 is elastically arranged on the sliding hoop 13 through a compression spring 92. Each protrusion 94 is slidably connected to a sliding groove 141 on the track 14 along the Z axis. A locking member is respectively arranged between each protrusion 94 and the track 14. The locking member can lock the protrusion 94 at any position on the track 14. Each protrusion 94 is located on the path of the ball 91 moving along the track 14. Specifically, a sliding groove 141 is provided on the track 14 along the length direction. The protrusion 94 is slidably engaged in the sliding groove 141, that is, the protrusion 94 can slide along the sliding groove 141 only in the length direction of the track 14, and cannot move relative to the track 14 in other directions. The locking member is preferably a locking bolt 95, each protrusion 94 has a groove, the locking bolt 95 is screwed on the protrusion 94, the nut of the locking bolt 95 is sunk in the groove, and the end of the locking bolt 95 away from the nut passes through the protrusion 94 and abuts against the track 14 (the bottom of the sliding groove 141).

[0039] The function of this embodiment is to adjust and adapt the position of each protrusion 94 according to the distribution interval of each nut to be tightened on the electrical hardware, and then lock the position of each protrusion 94 by a locking piece, so that the application scenario of the present invention is more extensive and can be suitable for the installation and disassembly of electrical hardware with nuts of different arrangement intervals.

[0040] When in use, during the process of rotating the insulating rod 1 to drive the electric wrench 3 to move along the track 14: when the ball 91 is not aligned with the protrusion 94, the compression spring 92 squeezes the ball 91 to the mouth of the shrinking groove, the part of the ball 91 protruding from the shrinking groove is in the sliding groove 141, and the ball 91 does not contact the track 14 (the inner wall of the sliding groove 141), and the rotation resistance of the insulating rod 1 is very small; when the ball 91 touches the protrusion 94, the ball 91 will overcome the elastic force of the compression spring 92 under the squeezing of the protrusion 94 and enter the inside of the shrinking groove. At this time, the rotation resistance of the insulating rod 1 is significantly increased. When the ball 91 is completely aligned with the groove on the protrusion 94, the elastic force of the compression spring 92 squeezes the ball 91 to the mouth of the shrinking groove, and the part of the ball 91 protruding from the shrinking groove enters the groove. The operator's hand will have a clear feeling when rotating the insulating rod 1, thereby knowing that the electric wrench 3 has been accurately aligned with the next nut to be tightened, and stopping rotating the insulating rod 1.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
