Description

Technical Field

[0001] The present invention relates to the technical field of electric power installation tools, and particularly to an electric installation tool for installing an insulating sheath on an exposed live body. Background Art

[0002] Insulating sheaths at the connection of the middle and low voltage side cross-bridge busbars, the grounding wire installation location, and the wall-penetrating bushing of the main transformer in a substation can effectively prevent problems such as phase-to-phase short circuits caused by foreign objects such as plastic sheets and kites falling on the equipment.

[0003] Currently, known insulating protective sheaths in the prior art usually include snap-type insulating sheaths, Velcro-type insulating sheaths, etc. Their specific structures usually have snap structures or Velcro structures at the edges of the insulating sheaths.

[0004] In order to improve safety in the existing operating environment, power is usually cut off for manual installation by workers, that is, workers need to wear insulating gloves for manual installation. Power cut-off involves power cut-off operations, arranging safety measures, permission briefings, work, acceptance, ending work, restoring on-site safety measures, restoring operations, etc., resulting in a long installation time for the insulating sheath, greatly affecting the installation efficiency, and being not conducive to the safe and reliable operation of the power grid, not meeting the requirements of safe production.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An electric installation tool for installing an insulating sheath on an exposed live body, including an insulating rod and an installation main body movably arranged at the end of the insulating rod, and further including a movable frame rotatably connected to the installation main body; two pressing strips, one of the pressing strips is movably arranged on the movable frame, and the other pressing strip is movably arranged on the installation main body; at least one clamping member, which includes two clamping units respectively arranged on the corresponding pressing strips, the clamping unit includes a sliding seat slidably connected to the corresponding pressing strip, a clamping piece is slidably connected to the sliding seat, and the clamping piece has a clamping position for clamping the insulating sheath during the process of sliding relative to the sliding seat. A locking member is arranged between the clamping piece and the sliding seat, and the locking member is assembled to lock the clamping piece in the clamping position and can be unlocked; when the movable frame rotates relative to the installation main body, it drives each locking member to unlock so that the corresponding clamping piece disengages from the clamping position, and then drives the two pressing strips to close and press the edge of the insulating sheath so that the insulating sheath is installed at the connection of the wire row.

[0007] Preferably, the locking member includes: a guiding groove, which includes a sliding groove formed on the clamping piece and a locking groove connected to the sliding groove; a circular lock head, which is slidably connected in the sliding seat; a sliding column, which is fixedly connected to the circular lock head, and the diameter of the sliding column is smaller than that of the circular lock head; a first elastic member, whose process of restoring elastic deformation drives the circular lock head to insert into the locking groove; a second elastic member, whose process of restoring elastic deformation drives the locking bar to slide relative to the sliding seat.

[0008] Preferably, during the process of the movable frame rotating relative to the mounting body, the sliding columns of the two clamping units of the clamping member are driven to abut against each other so that the circular lock head disengages from the locking groove until the sliding columns are aligned with the sliding groove. Then, during the process of the second elastic member restoring elastic deformation, the locking bar is driven to slide relative to the sliding seat so that the sliding column is in sliding fit with the sliding groove until the locking bar disengages from the locking position.

[0009] Preferably, an elastic soft rubber plate is fixedly connected to the clamping surface of each clamping piece.

[0010] Preferably, the mounting body includes a base threadedly connected to the insulating rod and a positioning frame rotatably connected to the base through a first rotating shaft. A first servo motor is provided on the base, and the output shaft of the first servo motor is coaxially and fixedly connected to the first rotating shaft.

[0011] Preferably, the movable frame is rotatably connected to the positioning frame of the mounting body through a second rotating shaft. A second servo motor is provided on the positioning frame, and the output shaft of the second servo motor is coaxially and fixedly connected to the second rotating shaft.

[0012] Preferably, each sliding seat is slidably connected to the corresponding pressing bar, and a locking bolt for locking the sliding seat is provided between each sliding seat and the corresponding pressing bar.

[0013] Preferably, the movable frame is slidably connected to the corresponding pressing bar through a first moving seat, and a first tightening mechanism for locking the first moving seat is provided between the first moving seat and the movable frame; the positioning frame is slidably connected to the corresponding pressing bar through a second moving seat, and a second tightening mechanism for locking the second moving seat is provided between the second moving seat and the positioning frame.

[0014] In the above technical solution, an electric installation tool for installing an insulating sheath on an exposed live body provided by the present invention first places the insulating sheath between two pressing strips in an open state, and then drives each clamping piece to slide relative to the sliding seat to clamp the edge of the insulating sheath, and transports the insulating sheath to the busbar connection through an insulating rod. Then, the movable frame is driven to rotate so that the two pressing strips are closed. Before the two pressing strips close and press the magic tape or snap structure on the edge of the insulating sheath, the locking member is triggered to unlock so that each clamping piece disengages from the clamping position. Finally, the two pressing strips continue to close and press the magic tape or snap structure on the edge of the insulating sheath to complete the wrapping and installation of the busbar connection and the like. Thus, the insulating rod increases the distance between the staff and the busbar connection so that the staff can complete the installation of the insulating sheath on the busbar connection without power outage. Moreover, during the transportation and installation process, the insulating sheath clamped on the installation main body not only avoids the risk of falling off the installation main body, but also improves the stability when installing the insulating sheath; the whole process reduces the installation time of the insulating sheath and improves the work efficiency to a certain extent.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings

[0030] Please refer to Figure 1-11, an electric installation tool for installing an insulating sheath on an exposed live body provided by an embodiment of the present invention includes an insulating rod 1, an installation main body 2 movably arranged at the end of the insulating rod 1, a movable frame 3, two pressing strips 4, and at least one clamping member. The movable frame 3 is rotatably connected to the installation main body 2; one of the pressing strips 4 is movably arranged on the movable frame 3, and the other pressing strip 4 is movably arranged on the installation main body 2; at least one clamping member, the clamping member includes two clamping units 5 respectively arranged on the corresponding pressing strips 4, the clamping unit 5 includes a sliding seat 51 slidably connected to the corresponding pressing strip 4, a clamping piece 52 is slidably connected to the sliding seat 51, and the clamping piece 52 has a clamping position for clamping the insulating sheath during the process of sliding relative to the sliding seat 51. A locking member 6 is arranged between the clamping piece 52 and the sliding seat 51, and the locking member 6 is assembled to lock the clamping piece 52 in the clamping position and can be unlocked; during the process of the movable frame 3 rotating relative to the installation main body 2, each locking member 6 is driven to unlock so that the corresponding clamping piece 52 is disengaged from the clamping position, and then the two pressing 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 busbar. Among them, it should be noted that the clamping piece 52 is arranged in an L shape as shown in Figure 5-6 . An elastic soft rubber plate is fixedly connected to the clamping surface of the clamping piece 52. At least one guide rod is fixedly connected to each sliding seat 51, the length direction of the guide rod is perpendicular to the length direction of the corresponding pressing strip 4, and the sliding direction of each clamping piece 52 relative to the sliding seat 51 is the length direction of the guide rod.

[0031] Specifically, first, place the insulating sheath between the two pressing strips 4 in the open state, and then drive each clamping piece 52 to slide relative to the sliding seat 51 to clamp the edge of the insulating sheath, and transport the insulating sheath to the connection of the busbar through the insulating rod 1, etc. Then drive the movable frame 3 to rotate so that the two pressing strips 4 are closed, and before the two pressing strips 4 close and press the magic tape or snap structure on the edge of the insulating sheath, trigger the locking member 6 to unlock so that each clamping piece 52 is disengaged from the clamping position. Finally, the two pressing strips 4 continue to close and press the magic tape or snap structure on the edge of the insulating sheath to complete the wrapping and installation of the connection of the busbar. Thus, the distance between the staff and the connection of the busbar is increased through the insulating rod 1 so that the staff can complete the installation of the insulating sheath on the connection of the busbar without power outage. Moreover, the insulating sheath clamped on the installation main body 2 during the transportation and installation process not only avoids the risk of falling from the installation main body 2 but also improves the stability during the installation of the insulating sheath; the whole process reduces the installation time of the insulating sheath and improves the work efficiency to a certain extent.

[0032] 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.

[0033] 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.

[0034] Among them, during the process of the movable frame 3 rotating relative to the installation main body 2, the sliding columns 63 of the two clamping units 5 of the clamping member are driven to abut against each other, so that the circular lock head 62 is disengaged from the locking groove 612 until the sliding columns 63 are aligned with the sliding grooves 611. After that, during the process of the second elastic member 65 recovering its elastic deformation, the locking bar is driven to slide relative to the sliding seat 51, so that the sliding columns 63 are in sliding fit with the sliding grooves 611 until the locking bar is disengaged from the locking position. Specifically, the preferred operation of the staff is to drive the movable frame 3 to rotate relative to the installation main body 2, so that the pressing strip 4 arranged on the movable frame 3 approaches and closes to the pressing strip 4 arranged on the installation main body 2. And during the approaching process, the sliding columns 63 in the two clamping units 5 of each clamping member will abut first, so as to compress the first elastic member 64, so that the circular lock head 62 is completely disengaged from the locking groove 612 and the sliding columns 63 are aligned with the sliding grooves 611, so that the sliding columns 63 can be in sliding fit with the sliding grooves 611, so as to facilitate the second elastic member 65 to drive the clamping piece 52 to retract along the length direction of the guide rod until it is disengaged from the clamping position, that is, the clamping of the insulating sheath can be released in the first time.

[0035] During the above process, when each clamping piece 52 releases the locking of the insulating sheath, at this time the insulating sheath is in a free state and has the risk of falling. Thus, as another preferred embodiment of the present invention, as Figure 7-10 shown, a pre-clamping mechanism 11 is further provided on each pressing strip 4. The pre-clamping mechanism 11 includes a pre-clamping plate 111 slidably connected to the pressing strip 4. A second spring 112 is provided between each pre-clamping plate 111 and the corresponding pressing 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 pressing strip 4. Specifically, when the two pressing strips 4 are in an open and closed state, under the action of the elastic force of the second spring 112 recovering its elastic deformation, the extrusion surface of the pre-clamping plate 111 protrudes from the abutting surface of the sliding column 63 in the locked state.

[0036] Specifically, during the rotation process 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 sliding columns 63 in the clamping member will abut against each other to release the locking of the corresponding clamping piece 52. Finally, the two pressing strips 4 will squeeze the edge of the insulating sheath to complete the installation. This process can reduce the risk of falling after each pressing strip 4 releases the clamping of the insulating sheath, and further improve the stability of installing the insulating sheath.

[0037] Among them, the installation main body 2 includes a base 21 threadedly connected to the insulating rod 1 and a positioning frame 22 rotatably connected to the base 21 through a first rotating shaft. A first servo motor 7 is provided on the base 21, and the output shaft of the first servo motor 7 is coaxially fixedly connected to the first rotating shaft. Among them, the first servo motor 7 is provided to drive the positioning frame 22 to rotate, so as to adapt to busbars with different inclinations.

[0038] Among them, the movable frame 3 is rotatably connected to the positioning frame 22 of the installation main body 2 through a second rotating shaft. A second servo 8 is provided on the positioning frame 22, and the output shaft of the second servo 8 is coaxially and fixedly connected to the second rotating shaft. Specifically, the second servo 8 is used to drive the rotating frame to rotate relative to the positioning frame 22 so that the pressing strip 4 provided on the movable frame 3 closes or separates from the pressing strip 4 on the positioning frame 22.

[0039] Among them, as a further preferred embodiment of the present invention, each sliding seat 51 is slidably connected to the corresponding pressing strip 4, and a locking bolt 9 for locking the sliding seat 51 is provided between each sliding seat 51 and the corresponding pressing strip 4. It should be noted that, according to the insulating sheaths of different sizes, the locking bolt 9 can be unscrewed or screwed tightly so that each sliding seat 51 slides relative to the corresponding pressing strip 4. Thus, the installation of insulating sheaths of different sizes can be completed, thereby improving the practicability of the entire device.

[0040] Among them, it further needs to be explained that the movable frame 3 is slidably connected to the corresponding pressing strip 4 through a first moving seat, and a first tightening mechanism 10 for locking the first moving seat is provided between the first moving seat and the movable frame 3; the positioning frame 22 is slidably connected to the corresponding pressing strip 4 through a second moving seat, and a second tightening mechanism for locking the second moving seat is provided between the second moving seat and the positioning frame 22. It should be noted that the structures of the first tightening mechanism 10 and the second tightening mechanism are the same. The first tightening mechanism 10 includes a first knob bolt 101 threadedly connected to the first moving seat. A first abutting block 102 capable of abutting against the movable frame 3 is slidably connected in the first moving 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 moving seat. A second abutting block capable of abutting against the positioning frame 22 is slidably connected in the second moving seat, and the second abutting block is rotatably connected to the second knob bolt. Specifically, when the first knob bolt is screwed tightly, at this time the corresponding first abutting block 102 approaches and abuts against the movable frame 3, and thus the corresponding pressing strip 4 can slide along the movable frame 3 and be locked; similarly, the pressing 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 sheaths can be more suitably placed in the U-shaped frame formed between the two pressing strips 4, the movable frame 3 and the positioning frame 22, which further facilitates the installation of the insulating sheaths and improves the stability of installing the insulating sheaths.

[0041] Only certain exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
