Power outage involves power outage operation, arrangement of safety measures, permit briefing, work, acceptance, termination of work, restoration of on-site safety measures, and resumption of operation. This results in a long installation time for the insulating sheath, which greatly affects the installation efficiency. It is not conducive to the safe and reliable operation of the power grid and does not meet the needs of safe production. Summary of the invention

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-11 The embodiment of the present invention provides an electric installation tool for installing an insulating sheath on a bare live body, comprising an insulating rod 1, a mounting body 2 movably arranged at the end of the insulating rod 1, a movable frame 3, two pressure strips 4 and at least one clamping member, wherein the movable frame 3 is rotatably connected to the mounting body 2; one of the pressure strips 4 is movably arranged on the movable frame 3, and the other pressure strip 4 is movably arranged on the mounting body 2; at least one clamping member, the clamping member comprises two clamping units 5 respectively arranged on the corresponding pressure strips 4, and the clamping unit 5 comprises a clamping unit slidably connected to the corresponding pressure strips 4, a clip 52 is slidably connected to the sliding seat 51, and during the sliding process of the clip 52 relative to the sliding seat 51, there is a clamping position for clamping the insulating sheath, and a locking member 6 is provided between the clip 52 and the sliding seat 51, and the locking member 6 is equipped to lock the clip 52 under the clamping position and can be unlocked; during the rotation of the movable frame 3 relative to the installation body 2, each locking member 6 is driven to unlock so that the corresponding clip 52 is separated from the clamping position, and then the two pressure strips 4 are driven to close and press the edge of the insulating sheath so that the insulating sheath is installed at the connection of the line row. Among them, it should be noted that the clip 52 is as Figure 5-6 As shown, the arrangement is L-shaped, and the clamping surface of the clip 52 is fixedly connected with an elastic soft rubber plate. Each sliding seat 51 is fixedly connected with at least one guide rod, and the length direction of the guide rod is perpendicular to the length direction of the corresponding pressure strip 4, and the sliding direction of each clip 52 relative to the sliding seat 51 is the length direction of the guide rod.

[0020] Specifically, the insulating sheath is first placed between the two pressure strips 4 in the open state, and then the edges of the insulating sheath are clamped by driving each clip 52 to slide relative to the sliding seat 51, and the insulating sheath is transported to the busbar connection through the insulating rod 1, etc., and then the movable frame 3 is driven to rotate to close the two pressure strips 4, and before the two pressure strips 4 are closed to press the Velcro or snap-on structure on the edge of the insulating sheath, the locking member 6 is triggered to unlock so that each clip 52 is disengaged from the clamping position, and finally the two pressure strips 4 continue to close and press the Velcro or snap-on structure on the edge of the insulating sheath to complete the wrapping and installation of the busbar connection. At this point, the distance between the staff and the busbar connection is increased by the insulating rod 1 so that the staff can complete the installation of the insulating sheath at the busbar connection without power outage, and the insulating sheath clamped on the installation body 2 during transportation and installation not only avoids the risk of falling from the installation body 2, but also improves the stability when installing the insulating sheath; the whole process reduces the installation time of the insulating sheath and improves work efficiency to a certain extent.

[0021] The locking member 6 includes a guide groove 61, a circular lock head 62, a slide post 63, a first elastic member 64 and a second elastic member 65. The guide groove 61 includes a slide groove 611 provided on the clip 52 and a locking groove 612 connected to the slide groove 611. The circular lock head 62 is slidably connected in the sliding seat 51. The slide post 63 is fixedly connected to the circular lock head 62, and the diameter of the slide post 63 is smaller than the diameter of the circular lock head 62. The process of the first elastic member 64 restoring elastic deformation drives the circular lock head 62 to be inserted into the locking groove 612. The process of the second elastic member 65 restoring elastic deformation drives the lock bar to slide relative to the sliding seat 51. It should be noted that the first elastic member 64 is an elastic telescopic post, one end of which is fixedly connected in the sliding seat 51, and the other end is fixedly connected to the circular lock head 62. It should be further explained that the second elastic member 65 is a first spring, which is sleeved on the corresponding guide rod, and one end of the first spring is fixedly connected to the sliding seat 51, and the other end is fixedly connected to the clip 52. It should be explained that the extrusion surface of any pressure strip 4 has a first horizontal surface and a second horizontal surface that match the clamping surface of the clip 52, and the second horizontal surface protrudes from the first horizontal surface on the extrusion surface of the pressure strip 4, so that the second horizontal surfaces of the two pressure strips 4 abut against the edge of the extruded insulating sheath, and it should be further explained that the abutting surfaces of the slide posts 63 abutting against each other protrude from the second horizontal surface when the corresponding clip 52 is located at the clamping position, so that the slide posts 63 of the two clamping units 5 of the clamping member abut against the two pressure strips 4 before the two pressure strips 4, thereby causing the locking member 6 to unlock.

[0022] Specifically, the process of clamping the insulating sheath before installation is as follows: after the insulating sheath is placed on the installation body 2, the staff only needs to press the clip 52 to make it slide along the length direction of the guide rod, and in the process of sliding, the slide rod and the slide groove 611 slide together until the circular lock head 62 is aligned with the locking groove 612. At this time, the elastic force of the first elastic member 64 restores the elastic deformation to drive the circular lock head 62 to be inserted into the locking groove 612, thereby completing the clamping of the insulating sheath by the clip 52.

[0023] Among them, the process of the movable frame 3 rotating relative to the installation body 2 drives the sliding posts 63 of the two clamping units 5 of the clamping member to abut against each other so that the circular lock head 62 disengages from the locking groove 612 until the sliding post 63 aligns with the sliding groove 611. Then, the second elastic member 65 restores its elastic deformation and drives the locking bar to slide relative to the sliding seat 51 so that the sliding post 63 and the sliding groove 611 slide together until the locking bar disengages from the locking position. Specifically, the staff preferably operates by driving the movable frame 3 to rotate relative to the installation body 2 so that the pressure strip 4 set on the movable frame 3 is closed and approached to the pressure strip 4 set on the installation body 2, and in the process of approaching, the sliding column 63 in the two clamping units 5 of each clamping member will abut first, thereby compressing the first elastic member 64 to make the circular lock head 62 completely disengage from the locking groove 612 and align the sliding column 63 with the sliding groove 611, so that the sliding column 63 and the sliding groove 611 can slide and cooperate, thereby facilitating the second elastic member 65 to drive the clip 52 to retreat along the length direction of the guide rod until it is out of the clamping position, that is, the clamping of the insulating sheath can be released in the first time.

[0024] In the above process, when each clip 52 releases the locking of the insulating sheath, the insulating sheath is in a free state and has the risk of falling. Figure 7-10 As shown, each pressure strip 4 is also provided with a pre-clamping mechanism 11, which includes a pre-clamping plate 111 slidably connected to the pressure strip 4, and a second spring 112 is provided between each pre-clamping plate 111 and the corresponding pressure strip 4, one end of the second spring 112 is fixedly connected to the pre-clamping plate 111, and the other end is fixedly connected to the pressure strip 4. Specifically, when the two pressure strips 4 are in the open and closed state, the extrusion surface of the pre-clamping plate 111 protrudes from the abutment surface of the sliding column 63 in the locked state under the action of the elastic force of the second spring 112 to restore the elastic deformation.

[0025] Specifically, during the rotation of the movable frame 3, the two pre-clamping plates 111 will first pre-clamp the edge of the insulating sheath (at this time, the corresponding second spring 112 is in a compressed state), and then the two slide posts 63 in the clamping member will abut against each other to release the lock of the corresponding clamping piece 52, and finally the two pressure strips 4 will squeeze the edge of the insulating sheath to complete the installation. This process can reduce the risk of each pressure strip 4 falling off after releasing the clamping of the insulating sheath, and further improve the stability of installing the insulating sheath.

[0026] The installation body 2 includes a base 21 threadedly connected to the insulating rod 1 and a positioning frame 22 rotatably connected to the base 21 via a first rotating shaft. The base 21 is provided with a first steering gear 7, and the output shaft of the first steering gear 7 is coaxially fixedly connected to the first rotating shaft. The positioning frame 22 is driven to rotate by the first steering gear 7 to adapt to busbars with different inclinations.

[0027] The movable frame 3 is rotatably connected to the positioning frame 22 of the installation body 2 via a second rotating shaft, and a second steering gear 8 is disposed on the positioning frame 22, and an output shaft of the second steering gear 8 is coaxially and fixedly connected to the second rotating shaft. Specifically, the second steering gear 8 is used to drive the rotating frame to rotate relative to the positioning frame 22 so that the pressure strip 4 disposed on the movable frame 3 is closed or separated from the pressure strip 4 on the positioning frame 22.

[0028] In a further preferred embodiment of the present invention, each sliding seat 51 is slidably connected to the corresponding pressure strip 4, and a locking bolt 9 for locking the sliding seat 51 is provided between each sliding seat 51 and the corresponding pressure strip 4. It should be noted that the locking bolt 9 can be unscrewed or tightened according to the insulating sheaths of different sizes, so that each sliding seat 51 slides relative to the corresponding pressure strip 4, so that the installation of the insulating sheaths of different sizes can be completed, thereby improving the practicality of the entire device.

[0029] It should be further explained that the movable frame 3 and the corresponding pressure strip 4 are slidably connected through the first movable seat, and a first tightening mechanism 10 is provided between the first movable seat and the movable frame 3 to lock the first movable seat; the positioning frame 22 and the corresponding pressure strip 4 are slidably connected through the second movable seat, and a second tightening mechanism is provided between the second movable seat and the positioning frame 22 to lock the second movable seat. It should be explained that the first tightening mechanism 10 has the same structure as the second tightening mechanism. The first tightening mechanism 10 includes a first knob bolt 101 threadedly connected to the first movable seat, a first abutting block 102 capable of abutting against the movable frame 3 is slidably connected in the first movable seat, and the first abutting block 102 is rotatably connected to the first knob bolt 101. The second tightening mechanism (not shown in detail in the figure) has the same structure as the first tightening mechanism. The second tightening mechanism includes a second knob bolt threadedly connected to the second movable seat, a second abutting block capable of abutting against the positioning frame 22 is slidably connected in the second movable seat, and the second abutting block is rotatably connected to the second knob bolt. Specifically, when the first knob screw is driven to tighten, the corresponding first abutment block 102 approaches and abuts against the movable frame 3, and the corresponding pressure strip 4 can slide along the movable frame 3 and be locked; similarly, the pressure strip 4 on the positioning frame 22 can also slide along the positioning frame 22 and be locked. The above process can further use insulating sheaths of different sizes, so that the insulating sheath is more appropriately placed in the U-shaped frame formed between the two pressure strips 4, the movable frame 3 and the positioning frame 22, further facilitating the installation of the insulating sheath and improving the stability of the installed insulating sheath.

[0030] 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.
