Description

Technical Field

[0001] The present invention relates to the technical field of electric power construction equipment, in particular to auxiliary equipment for installing long-distance power transmission lines. Background Art

[0002] In high-voltage transmission lines, split conductors are arranged in parallel with multiple sub-conductors to achieve long-distance, low-loss power transmission. Spacers, as key protective hardware, are installed on the conductors to fix the mutual spacing between the sub-conductors, thereby reducing the potential gradient on the surface of the conductors and reducing corona losses. At the same time, they avoid the mutual attraction and collision of the conductor bundles caused by electromagnetic forces when a short circuit occurs in the line. Currently, the installation of spacers mainly relies on manual operation. Since the weight of this component is between 5 and 8 kilograms, operators need to use a conductor crawler when working on high-altitude conductors. The spacers to be installed are placed in the crawler in advance for easy access, and the crawler is pulled to move in coordination while walking on the conductor to complete the installation task of the entire line.

[0003] Existing conductor climbing vehicles typically consist of a basket for placing spacers and a pulley frame mounted above the basket. The pulleys on the pulley frame engage the conductors to slide the basket along them. However, during the installation of the spacers, the relative distances between the sub-conductors are large, requiring significant manual force to pull the conductors into the corresponding conductor-receiving rings on the spacers. This makes installation difficult and inefficient. Summary of the Invention

[0006] Furthermore, a accommodating ring is formed at the free end of the connecting arm, and the outer surface of the accommodating ring forms a limited position plane along its tangent direction. The hanging part located at the first end is provided with a hanging pin and a side plate. When the hanging pin is inserted into the accommodating ring, the side plate abuts against the limiting plane.

[0007] Furthermore, a limiting assembly is provided on the lifting part located at the second end, and the limiting assembly can switch between a first state and a second state.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] like Figures 1 to 12As shown, an embodiment of the present invention provides an auxiliary device for the installation of long-distance power transmission lines, including a device body, the device body having a first end and a second end in the length direction of the conductor 101, the first end and the second end are both provided with an end spacer 102, a plurality of middle spacers 103 are stacked in sequence between the two end spacers 102, the end spacers 102 and the middle spacers 103 both include a frame 104 and a connecting arm 105 extending outward from the corner of the frame 104, the free end of the connecting arm 105 can be connected to the conductor 101, and the connecting arm 105 and the conductor 101 are both a preset number; the connecting arm 105 of the end spacer 102 faces the conductor 101, and the first end and the second end are both provided with a preset number of hanging parts 201, the hanging parts 201 are located at the free end of the connecting arm 105 of the end spacer 102 to connect the conductor 101 and the end spacer 102, and a roller assembly is provided on the hanging part 201, which is used to move the device body along the length direction of the conductor 101.

[0035] The wire 101 is connected to the end spacer 102 through the hanging piece 201, and the hanging piece 201 is located at the free end of the connecting arm 105 of the end spacer 102, so that the hanging piece 201 brings the relative distance of all the wires 101 closer to the installation distance of the free end of the connecting arm 105. During installation, only a small auxiliary force needs to be applied manually to pull the wire 101 into the wire 101 accommodating ring 109 at the free end of the connecting arm 105, thereby reducing the installation difficulty and improving construction efficiency.

[0036] For the convenience of description below, the two ends of the device body are divided into a first end and a second end. Figure 2 and Figure 5 In the figure, the right side is the first end, the left side is the second end, the spacer located at the first end or the second end is the end spacer 102, and the spacer located between the two end spacers 102 is the middle spacer 103. Figure 1 As shown, both the end spacers 102 and the middle spacers 103 (hereinafter collectively referred to as spacers) include a frame 104 and connecting arms 105. Frame 104 is a regular polygon with a preset number of sides, equal to the number of connecting arms 105. For example, if the preset number is four, the frame 104 has four sides, and the connecting arms 105 are also four, positioned at the corners of the frames 104. The spacers include two stacked frames 104, with the connecting arms 105 positioned between them. The frames 104 are hollowed out, ensuring structural strength while achieving lightweight design. The structure of the spacers described above is conventional and will not be described in detail here.

[0037] Among them, see Figure 3 and Figure 4The hoisting member 201 includes a first C-shaped member 106 and a second C-shaped member 107. The openings of the first C-shaped member 106 and the second C-shaped member 107 are arranged opposite each other, and one end of the first C-shaped member 106 and the second end can be opened and removably connected by a bolt and nut. The roller assembly includes two guide rollers 108 rotatably disposed within the first C-shaped member 106 and the second C-shaped member 107. The circumferential surface of the guide rollers 108 is concave, and the concave surface has a larger diameter to accommodate wires 101 of different diameters. By slightly adjusting the tightening degree of the bolts and nuts on the opening and closing sides, the distance between the two guide rollers 108 is changed to clamp wires 101 of different diameters. Moreover, when the device body moves along the length of the wire 101, the guide rollers 108 roll. When the bolts and nuts on the opening and closing sides are tightened, the two guide rollers 108 clamp the wire 101, allowing the device body to be stationary relative to the wire 101 to facilitate the installation of the spacer rod. In addition, the construction workers also carry devices such as safety ropes, the structure and setting method of which are existing technologies and will not be described in detail here.

[0038] In one embodiment, see Figure 3 and Figure 4 A accommodating ring 109 is formed at the free end of the connecting arm 105, and the outer surface of the accommodating ring 109 forms a limiting plane 202 along its tangent direction. A hanging pin 203 and a side plate 204 are provided on the hanging piece 201 located at the first end. When the hanging pin 203 is inserted into the accommodating ring 109, the side plate 204 abuts against the limiting plane 202.

[0039] The connecting arm 105 is connected to the hanging member 201 via the hanging pin 203 , and the side plate 204 abuts against the limiting plane 202 to limit the end spacer rod 102 at the first end from rotating relative to the hanging member 201 .

[0040] Two corresponding sets of limiting planes 202 and side plates 204 are provided, located at either end of the hook pin 203. The containment ring 109 comprises two halves: a first half-ring and a second half-ring. The inner end of the first half-ring is fixed to the free end of the connecting arm 105, while the outer end of the first half-ring is hinged to the outer end of the second half-ring. The inner end of the second half-ring can be locked to the free end of the connecting arm 105 via a pin. When the second half-ring is opened, the opening direction of the first half-ring becomes the direction in which the containment ring 109 can open. The structure of the containment ring 109 is known from the prior art and will not be described in detail here.

[0041] In one embodiment, a limiting assembly is provided on the hanging piece 201 located at the second end, and the limiting assembly can switch between a first state and a second state. When in the first state, the limiting assembly limits the first component, which is the end spacer 102 located at the second end, and cancels the limit on the second component, which is a middle spacer 103 adjacent to the first component; when in the second state, the limiting assembly cancels the limit on the first component to remove the first component, and limits the second component.

[0042] When in the first state, the limiting assembly limits the first component and cancels the limit on the second component. At this time, the end spacers 102 and the middle spacers 103 cannot be removed. When in the second state, the limiting assembly cancels the limit on the first component. At this time, the first component can be removed for installation, and the second component is limited to prevent the middle spacer 103 from falling. The middle spacer 103 is transformed into a new end spacer 102. By switching the limiting assembly between the first and second states, it is easy to remove the end spacers 102 from the equipment body, further reducing the difficulty of installation and improving construction efficiency.

[0043] In the process of removing the end spacer 102, the first end is a closed end and the second end is an open end, that is, the end spacer 102 can only be removed from the second end. The device body moves along the length direction of the wire 101, with the first end located in the front and the second end located in the back. When the device body moves to the installation position, the end spacer 102 is removed from the second end, that is, the back of the device body, and then installed. After that, the device body continues to move forward and the next installation process is carried out. This cycle completes all installation work of the current wire 101.

[0044] Among them, see Figure 7 A connecting rod 205 is provided on the hanging piece 201 at the second end, and the limiting assembly is provided at the end of the connecting rod 205 away from the hanging piece 201.

[0045] In one embodiment, the limiting assembly includes a first rod 206 and a second rod 207, and the ends of the first rod 206 and the second rod 207 are both provided with a blocking piece 208; when the limiting assembly is in a first state, the first rod 206 passes through the first component, and the blocking piece 208 of the first rod 206 abuts against the side wall of the first component to limit the first component; when the limiting assembly is in a second state, the blocking piece 208 of the first rod 206 is disengaged from the side wall of the first component to cancel the limitation of the first component, and the second rod 207 passes through the second component, and the blocking piece 208 of the second rod 207 abuts against the side wall of the second component to limit the second component.

[0046] Among them, see Figure 10The stopper 208 can be fan-shaped or circular, with a diameter greater than that of the first rod 206 or the second rod 207. When the stop assembly is in the first state, the first rod 206 passes through the inner hole of the first component and is positioned at the corner of the inner hole of the end spacer 102. Simultaneously, the stopper 208 of the first rod 206 abuts against the sidewall of the first component, thereby retaining the first component. Similarly, when the stop assembly is in the second state, the second rod 207 also retains the second component.

[0047] In one embodiment, see Figures 6 to 11 , the connecting arm 105 of the middle spacer bar 103 and the connecting arm 105 of the end spacer bar 102 form a first angle; an inner hole is formed in the frame 104, and the limiting assembly also includes a support member 209, which is arranged on the lifting member 201 at the second end, and an arc groove 210 is provided on the support member 209, the center of the arc groove 210 is located in the inner hole, and the radius of the arc groove 210 is smaller than the radius of the inscribed circle of the inner hole; the first rod 206 and the second rod 207 both have a fixed end and a telescopic end, the fixed end moves along the arc groove 210, and the baffle 208 is provided at the telescopic end; when the limiting assembly is in the first state, the first component and the second component are pulled by the first external force, so that the telescopic end of the first rod 206 is extended, and the second component passes over the telescopic end of the second rod 207; the first rod 206 is extended by the second external force The component and the second component rotate synchronously by a second angle, and the rotation axis passes through the center of the inscribed circle of the inner hole, so that the first rod 206 moves from the middle of the arc groove 210 to one end thereof, and the second rod 207 faces the inner hole of the second component; the first component and the second component are pushed by a third external force, so that the telescopic end of the first rod 206 is shortened, and the second rod 207 is inserted into the inner hole of the second component; the first component and the second component are synchronously rotated by a fourth external force by a third angle, so that the first rod 206 moves to one end of the arc groove 210, the second rod 207 moves to the middle of the arc groove 210, and the blocking piece 208 of the first rod 206 is disengaged from the side wall of the first component, and the blocking piece 208 of the second rod 207 abuts against the side wall of the second component, and the limit assembly is in the second state; the sum of the second angle and the third angle is equal to the first angle.

[0048] When the limiting assembly is in the first state, the first component and the second component are pulled by a first external force, and the first component pulls the telescopic end of the first rod 206 through the blocking piece 208 to extend it, and the second component passes over the telescopic end of the second rod 207. At this time, the second rod 207 has no limit on the second component; then the first component and the second component are synchronously rotated by a second external force at a second angle, and the rotation axis passes through the center of the inscribed circle of the inner hole. The first rod 206 moves from the middle of the arc groove 210 to one end thereof, and the second rod 207 faces the inner hole of the second component, that is, the second rod 207 can pass through the second component; then the first component and the second component are pushed by a third external force to restore them to their original positions, so that the telescopic end of the first rod 206 is shortened, and the second rod 207 is The rod 207 is inserted into the inner hole of the second component, that is, the second rod 207 passes through the second component; the first component and the second component continue to rotate synchronously by a third angle through a fourth external force, the first rod 206 moves to one end of the arc groove 210, and the second rod 207 moves to the middle of the arc groove 210. Since the radius of the arc groove 210 is smaller than the radius of the inscribed circle of the inner hole, the movement paths of the first component and the first rod 206 are different, so that the blocking piece 208 of the first rod 206 is disengaged from the side wall of the first component to cancel the limit on the first component. At this time, the first component can be taken out for installation; the blocking piece 208 of the second rod 207 abuts against the side wall of the second component to limit the second component, and the limit assembly is in the second state.

[0049] By first pulling and rotating, and then pushing to reset and reversely rotating the first and second components, the first component is no longer restricted and can be removed for installation. At the same time, the second component is restricted to prevent the middle spacer bar 103 from falling, and the middle spacer bar 103 is transformed into a new end spacer bar 102, thereby realizing the process of recycling the spacer bars.

[0050] Among them, due to the connection method between the first end hanging piece 201 and the corresponding end spacer 102, the hanging piece 201 at the first end is equivalent to increasing the arm length of the connecting arm 105 of the corresponding end spacer 102, so it has an outward expansion effect on the wire 101 at this location; due to the connection method between the second end hanging piece 201 and the corresponding end spacer 102, that is, pulling the first rod 206 and the hanging piece 201 through the corresponding end spacer 102 to produce an inward pulling effect on the wire 101 at this location, so that the spacing of the wires 101 at this location is closer to the relative distance of the accommodating ring 109 of the end spacer 102, further reducing the manual application of smaller auxiliary force and reducing the difficulty of installation.

[0051] A limit rod 211 is mounted on the device body via a connector. The limit rod 211 is parallel to the length of the conductors 101 and passes through a receiving ring 109 of the connecting arms 105 of the middle spacer bars 103. This ensures that the connecting arms 105 of all middle spacer bars 103 face the same direction, i.e., toward the center between two adjacent conductors 101. When the second component needs to be rotated, the limit rod 211 is removed from the receiving ring 109 of the connecting arm 105 of the middle spacer bar 103. The first angle is 360° / (2×preset number). For example, if the preset number is 4, i.e., there are 4 connecting arms 105 and 4 conductors 101, the first angle is 360° / (2×4)=45°. For another example, if the preset number is 6, i.e., there are 6 connecting arms 105 and 6 conductors 101, the first angle is 360° / (2×6)=30°.

[0052] The first rod 206 and the second rod 207 have the same structure, and their telescopic ends can slide and telescope relative to the fixed end, and a tension spring 212 is provided between the telescopic end and the fixed end, so that the telescopic end has a tendency to move toward the fixed end.

[0053] The first rod 206 and the second rod 207 can move synchronously or asynchronously along the arc groove 210. Preferably, the first rod 206 and the second rod 207 can move synchronously along the arc groove 210. Figure 8 and Figure 9 A curved plate 213 is slidably disposed within the curved groove 210. The curved plate 213 can only move along the curved groove 210 and will not fall out of the curved groove 210. The central angle of the curved plate 213 is half of the central angle of the curved groove 210. The fixed end of the first rod 206 is disposed at one end of the curved plate 213, and the fixed end of the second rod 207 is disposed at the other end of the curved plate 213. This allows the first rod 206 to be located at one end of the curved groove 210 when the first rod 206 is located at the other end of the curved groove 210, and the second rod 207 to be located at the middle of the curved groove 210 when the first rod 206 is located at the other end of the curved groove 210. In this case, when the first component and the second component are synchronously rotated by a second external force at a second included angle, the first rod 206 and the second rod 207 move synchronously along the curved groove 210 until the second rod 207 faces the inner hole of the second component.

[0054] When the first rod 206 and the second rod 207 move asynchronously along the arcuate slot 210, the fixed ends of the first rod 206 and the second rod 207 both move along the arcuate slot 210, and the fixed ends of the first rod 206 and the second rod 207 can only move along the arcuate slot 210 and cannot fall out of the arcuate slot 210. In this case, when the first component and the second component are caused to rotate synchronously by a second external force at a second included angle, the first rod 206 moves from the middle of the arcuate slot 210 to one end thereof, while the second rod 207 remains stationary within the arcuate slot 210. During the rotation of the second component, the second rod 207 can be directed toward the inner hole of the second component earlier than when the first rod 206 and the second rod 207 move synchronously along the arcuate slot 210.

[0055] The first and third external forces are of equal magnitude, opposite in direction, and act for the same duration. The second and fourth external forces are of equal magnitude, identical in direction, and may act for the same or different durations. After all of the above external forces have been applied, the first rod 206 moves from the middle of the arcuate slot 210 to one end thereof, and the second rod 207 moves from the other end of the arcuate slot 210 to its middle. Furthermore, the original first component is removed, and the original second component becomes the new first component. When the first component is subsequently removed, the second and fourth external forces are applied in opposite directions, causing the first and second components to rotate synchronously in opposite directions by the second and third angles, causing the first rod 206 to move again from one end of the arcuate slot 210 to its middle, and the second rod 207 to move again from the middle of the arcuate slot 210 to its other end. This cycle repeats, allowing the first components to be removed one by one.

[0056] In addition, the radius of the arcuate groove 210 can be set selectively. There is a preferred radius of the arcuate groove 210, which allows the conductor 101 to exactly correspond to the receiving ring 109 of the first component. At this time, the receiving rings 109 of the end spacer 102 and the middle spacer 103 are both in an open state. Since the second external force or the fourth external force applied in the two successive removals of the spacer are in opposite directions, the openings of the receiving rings 109 of adjacent spacer bars for all spacer bars are in opposite directions. For example, Figure 6 When the second external force or the fourth external force is applied to cause the first component and the second component to rotate synchronously clockwise at the second angle or the third angle, the opening direction of the accommodating ring 109 of the first component is counterclockwise, while the opening direction of the accommodating ring 109 of the end spacer rod 102 near the second end is clockwise, so as to avoid motion interference with the wire 101 during rotation.

[0057] In one embodiment, see Figure 9A groove 214 is also provided on the support member 209, and the groove 214 is located in the middle of the arc groove 210. When the first rod 206 or the second rod 207 moves to the middle of the arc groove 210, the groove 214 limits the first rod 206 or the second rod 207 to prevent the first rod 206 or the second rod 207 from sliding along the arc groove 210 due to the inward pulling force of the end spacer rod 102.

[0058] When the first rod 206 and the second rod 207 can move synchronously along the arc groove 210, see Figure 9 and Figure 10 Guide rods 215 are provided at both ends of the arc-shaped plate 213. Guide holes 216 are provided at the fixed ends of the first rod 206 and the second rod 207. In the radial direction of the arc-shaped slot 210, the size of the guide holes 216 is larger than that of the guide rods 215. This allows the first rod 206 or the second rod 207 to move slightly radially along the arc-shaped slot 210 when the first rod 206 or the second rod 207 moves along the arc-shaped slot 210 and sinks into the groove 214. Furthermore, when the first rod 206 or the second rod 207 moves along the arc-shaped slot 210 asynchronously, or when the first rod 206 or the second rod 207 moves along the arc-shaped slot 210 and directly sinks into the groove 214, the first rod 206 or the second rod 207 can also move slightly radially along the arc-shaped slot 210.

[0059] In one embodiment, the maximum length that the telescopic end can extend relative to the fixed end is greater than three times the thickness of the frame 104 .

[0060] When the position-limiting assembly is in the first state, the telescopic ends of the first rod 206 and the second rod 207 have both extended relative to their fixed ends by a distance equal to the thickness of the frame 104. Therefore, the first rod 206 has already secured the first component, while the second rod 207 is also ready to secure the second component. When the first and second components are pulled together by a first external force, the telescopic end of the first rod 206 extends by twice the thickness of the frame 104, allowing the second component to just pass over the telescopic end of the second rod 207.

[0061] In one embodiment, see Figure 6 A circular mounting plate 301 is provided at both the first and second ends, and a support rod 303 is provided between the two mounting plates 301. The axis of the mounting plate 301 and the axis of the support rod 303 are both parallel to the length direction of the wire 101. The axis of the support rod 303 is spaced apart from the axis of the mounting plate 301, and multiple support rods 303 are arranged at equal intervals along the circumference of the mounting plate 301. The support rods 303 pass through the inner hole to support the frame 104.

[0062] When multiple middle spacer bars 103 are stacked in sequence between two end spacer bars 102, the support rod 303 passes through the inner hole to stably support the end spacer bars 102 and the middle spacer bars 103, and the length of the support rod 303 can be selected according to the number of middle spacer bars 103 to be carried, thereby increasing the number of middle spacer bars 103 carried at a time and saving construction time.

[0063] Both mounting plates 301 are circular, and the multiple support rods 303 form a circle along the circumference of the mounting plates 301, which serves as the inscribed circle of the inner hole of the frame 104. The mounting plate 301 at the first end has a larger diameter than the inscribed circle of the inner hole of the frame 104, thereby blocking and limiting the end spacer rods 102 at the first end. The mounting plate 301 at the second end has a smaller diameter than the inscribed circle of the inner hole of the frame 104, allowing the end spacer rods 102 to be removed from the second end.

[0064] In one embodiment, see Figure 12 The mounting plate 301 includes a first disk body 304 and a second disk body 305 which are circular and can rotate relative to each other. A locking member 306 is provided between the first disk body 304 and the second disk body 305 to limit the relative rotation of the two. An intermediate rod is provided between the two first disk bodies 304. A first slide groove 307 is provided on the first disk body 304. The first slide groove 307 is formed along a preset trajectory. The line connecting the starting point and the end point of the preset trajectory is set at an angle to the radial direction of the first disk body 304. A second slide groove 308 is provided on the second disk body 305 along its radial direction. The end of the support rod 303 passes through the first slide groove 307 and extends into the second slide groove 308.

[0065] When the first disk body 304 and the second disk body 305 rotate relative to each other, the second slide groove 308 on the second disk body 305 makes the support rod 303 tend to move tangentially along the mounting disk 301, and the support rod 303 simultaneously moves along the first slide groove 307 on the first disk body 304. Therefore, the support rod 303 can move between the starting point and the end point of the first slide groove 307 to change the distance between the support rod 303 and the axis of the mounting disk 301, thereby adjusting the size of the circular area enclosed by all the support rods 303, which is suitable for supporting end spacers 102 or middle spacer frames 104 of different sizes, thereby improving the scope of application.

[0066] For ease of use, handles 309 are provided on both the first tray 304 and the second tray 305. By keeping one handle 309 stationary and rotating the other handle 309, the first tray 304 and the second tray 305 can rotate relative to each other. Both the first tray 304 and the second tray 305 have sidewalls. The locking member 306 is a bolt threadedly connected to the sidewall of the first tray 304. The end of the locking member 306 can abut against the sidewall of the second tray 305. Tightening the locking member 306 restricts relative rotation between the first tray 304 and the second tray 305.

[0067] The end of the support rod 303 contracts inward and then extends along the direction of the support rod 303 , and the extended portion passes through the first sliding groove 307 and extends into the second sliding groove 308 .

[0068] In one embodiment, the preset trajectory is a spiral line, a straight line, an arc line, etc., which is not limited here.

[0069] When the present invention is in use, the frame 104 is sequentially sleeved on the support rod 303 to stably support the end spacers 102 and the middle spacers 103, thereby stacking multiple middle spacers 103 in sequence between the two end spacers 102. Afterwards, the equipment body and the construction personnel are hoisted to the construction height, and the hoisting parts 201 are respectively installed on the corresponding wires 101. The hoisting parts 201 connect the wires 101 with the end spacers 102, and the hoisting parts 201 are located at the free end of the connecting arm 105 of the end spacer 102, so that the hoisting parts 201 bring the relative distance of all the wires 101 closer to the installation distance of the free end of the connecting arm 105. During installation, only a small auxiliary force needs to be applied manually to pull the wires 101 into the wire 101 accommodating ring 109 at the free end of the connecting arm 105, thereby reducing the difficulty of installation and improving construction efficiency.

[0070] The roller assembly on the hoisting part 201 enables the equipment body, i.e., the construction personnel, to move along the length of the conductor 101, and stops when the equipment body moves to the position to be installed, so as to carry out the installation of the spacer rod. Specifically: under normal conditions, the limit assembly is in the first state, the first rod 206 is inserted into the inner hole of the first component, and the baffle 208 of the first rod 206 abuts against the side wall of the first component to limit the first component; the first component and the second component are pulled by a first external force, and the first component pulls the telescopic end of the first rod 206 through the baffle 208 to extend it, and the second component passes over the telescopic end of the second rod 207, at which time the second rod 207 has no limit on the second component; then the first component and the second component are synchronously rotated by a second external force to a second angle, and the axis of rotation passes through the center of the inscribed circle of the inner hole, and the first rod 206 moves from the middle of the arc groove 210 to one end thereof, and the second rod 207 faces the inner hole of the second component, that is, the second rod 207 can pass through the second component; then the first component and the second component are pushed by a third external force. The second component is restored to its original position by the fourth external force, so that the telescopic end of the first rod 206 is shortened, and the second rod 207 is inserted into the inner hole of the second component, that is, the second rod 207 passes through the second component; the first component and the second component continue to rotate synchronously by a third angle through the fourth external force, the first rod 206 moves to one end of the arc groove 210, and the second rod 207 moves to the middle of the arc groove 210. Since the radius of the arc groove 210 is smaller than the radius of the inscribed circle of the inner hole, the movement paths of the first component and the first rod 206 are different, so that the blocking piece 208 of the first rod 206 is disengaged from the side wall of the first component to cancel the limit on the first component. At this time, the first component can be taken out for installation; the blocking piece 208 of the second rod 207 abuts against the side wall of the second component to limit the second component, and the limit assembly is in the second state.

[0071] In summary, by first pulling and rotating, and then pushing to reset and reversely rotating the first and second components, the first component is no longer limited and can be removed for installation. At the same time, the second component is limited to prevent the middle spacer bar 103 from falling, and the middle spacer bar 103 is transformed into a new end spacer bar 102, thereby realizing the process of recycling the spacer bars.

[0072] The above description is only a specific embodiment of the present invention, and various examples do not limit the essential content of the present invention.
