Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, in particular to an auxiliary tool for installing and removing cables in a small curve radius section. Background Art

[0002] Small curve radius sections refer to those sections in railways or rail transit lines with smaller curve radii. Due to the terrain, design or functional requirements, the direction of the railways or tracks in these sections will form a certain curvature. If the radius of this curvature is small, it is called a small curve radius section.

[0003] When installing and removing cables in these areas with small curve radii, the construction difficulty will be greatly increased because the cables need to be laid along curved tracks or railways; traditional manual installation methods such as pushing, pulling, carrying and pedaling are not only inefficient, but also pose great safety hazards, especially when working at high altitudes, the safety of construction workers cannot be effectively guaranteed, so further optimization is made to the above problems. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a cable installation and removal auxiliary tool for areas with small curve radius. By driving the hydraulic support rod up and down through the driving assembly, it can not only assist the workers in removing or installing the cables and reduce the construction difficulty, but also improve the workers' construction efficiency.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: an auxiliary tool for cable installation and removal in a small curve radius section, comprising a support rod, a hydraulic support rod and a support seat, wherein the support seat is arranged on the surface of the right end of the support rod, and a rotating assembly is arranged on the surface of the right end of the support rod and near the support seat, and the hydraulic support rod is arranged inside the rotating assembly, and a load-bearing rod is arranged on the surface of the right end of the hydraulic support rod, and a cable is slidably connected to the upper surface of the load-bearing rod, and a clamping ring is arranged on the surface of the middle part of the hydraulic support rod, and a lithium battery is detachably connected inside the clamping ring; The surfaces of the left ends of the support rod and the hydraulic support rod are provided with a positioning ring 1 and a positioning ring 2, the top of the positioning ring 1 is provided with a vertical rod, the top of the positioning ring 2 is provided with an auxiliary rod, and the interior of the vertical rod is provided with a driving component and is used in conjunction with the auxiliary rod.

[0006] The present invention has the following beneficial effects: The utility model discloses an auxiliary tool for laying and removing cables in a small curve radius section. Through the positioning ring 1 and the positioning ring 2 on the surface of the support rod and the hydraulic support rod, the hydraulic support rod can be rotated with the positioning ring 2 as the rotation axis. When laying or removing the cable, the hydraulic support rod is held by hand, and the load-bearing rod is driven to be extended and retracted through the output end of the hydraulic support rod, so that the cable on the surface can be laid or removed. The auxiliary rod can be driven to move up and down by the driving component, so as to adjust the use position of the hydraulic support rod, reduce manual adjustment, save time and labor, not only reduce the difficulty of construction, but also improve the efficiency of construction. The utility model relates to an auxiliary tool for installing and removing cables in a small curve radius section. The arc plate on the top of the support seat can be shrunk according to the thickness of the cable, so that the support can be adaptively adjusted according to the specifications of the cable. The top of the auxiliary rod and the left end of the cross rod can be quickly disassembled and assembled, so that it can be adjusted according to the use requirements. The utility model relates to an auxiliary tool for installing and removing cables in a small curve radius area. Through positioning ring 1 and positioning ring 2, the vertical rod and the auxiliary rod can be rotated 90 degrees to the left or right, so that they can be conveniently retracted on the surface of the support rod and the hydraulic support rod, and are easy to carry. When the vertical rod is rotated 90 degrees to the left and is in a vertical state, the auxiliary belt is used to drive the tooth plate to move to the left. At this time, the gear rod synchronously drives the rotating sleeve rod to rotate, so that the adjustment seat moves to the right, which is convenient for increasing the supporting range of the cable and reducing the downward pulling force at both ends of the cable when supporting. The utility model relates to an auxiliary tool for installing and removing cables in a small curve radius section. When the tooth plate moves to the left, the pressure plate drives the extrusion rod to move to the left, thereby squeezing the gas inside the compression chamber to expand the rubber layer. When the threshold value set by the pressure sensor is reached, the solenoid valve is turned on and the air flow is discharged from the exhaust hole, so that the dirt on the top of the support seat and the position of the arc plate can be cleaned conveniently, reducing manual cleaning.

[0011] A rotating assembly is provided on the surface of the right end of the support rod 1, near the support seat 3, and the hydraulic support rod 2 is arranged inside the rotating assembly. The rotating assembly includes a fixing ring 12 arranged on the surface of the support rod 1 and a fixing ring 2 13 arranged on the surface of the hydraulic support rod 2. The fixing ring 12 is rotatably connected to the fixing ring 2 13 through a rotating shaft.

[0012] like Figure 1-Figure 2 As shown, the fixing ring 12 and the fixing ring 2 13 are fixedly connected to the surface of the right end of the support rod 1 and the hydraulic support rod 2 by bolts, and the fixing ring 12 and the fixing ring 2 13 are connected by a rotating shaft. When the left end of the handheld hydraulic support rod 2 moves up and down, the other end thereof rotates with the rotating shaft as the center of the circle, so that the cable 5 falls on the surface of the load-bearing rod 4, so as to facilitate the removal or installation of the cable 5.

[0013] A load-bearing rod 4 is provided on the surface of the right end of the hydraulic strut 2, and a cable 5 is slidably connected to the upper surface of the load-bearing rod 4. A clamp ring 6 is provided on the surface of the middle part of the hydraulic strut 2, and a lithium battery 7 is detachably connected inside the clamp ring 6. A connecting wire 30 is provided on the left end of the hydraulic strut 2, and the other end of the connecting wire 30 is used in conjunction with the lithium battery 7. like Figure 1 As shown, the surface of the clamping ring 6 is provided with a U-shaped clamping plate, and is adapted to the lithium battery 7. When disassembling or assembling, the lithium battery 7 is clamped inside the U-shaped clamping plate, and a fastening ring is threadedly connected on one side of the U-shaped clamping plate, and the other end thereof passes through the U-shaped clamping plate and extends to the surface of the lithium battery 7, so as to facilitate its fastening and facilitate later disassembly or assembly and replacement.

[0014] It can be connected to the lithium battery 7 through the connecting line 30 to provide a power source for the hydraulic support rod 2. A display and buttons are provided on the surface of the lithium battery 7, and operation buttons are provided on the surface of the hydraulic support rod 2 near the connecting line 30 to facilitate operation.

[0015] The surfaces of the left ends of the support rod 1 and the hydraulic support rod 2 are provided with a positioning ring 1 8 and a positioning ring 2 9, the top of the positioning ring 1 8 is provided with a vertical rod 10, the top of the positioning ring 2 9 is provided with an auxiliary rod 11, and the interior of the vertical rod 10 is provided with a driving assembly and is used in conjunction with the auxiliary rod 11.

[0016] The driving assembly includes a driving block 14 arranged in the top of the vertical rod 10, a screw rod 15 arranged at the output end of the driving block 14, and a cross rod 16 arranged on the surface of the screw rod 15. The left end of the cross rod 16 is detachably connected to the top of the auxiliary rod 11. A limiting groove 33 is provided at the bottom end of the vertical rod 10. A limiting rod 34 is inserted into the outer wall of the bottom of the fixing ring 12. The top of the limiting rod 34 passes through the fixing ring 12 and the support rod 1 and extends to the inside of the limiting groove 33. A spring 35 is sleeved on the surface of the middle part of the limiting rod 34.

[0017] like Figure 4 As shown, in order to maintain the stability of the vertical rod 10 in the vertical state, the limiting rod 34 can extend its top end to the inside of the limiting groove 33 through the force of the spring 35 to maintain the stability of use. When the vertical rod 10 needs to be retracted on the surface of the support rod 1, the bottom end of the limiting rod 34 is held and pulled downward to move the top end out of the limiting groove 33, and then the vertical rod 10 is rotated 90° to the right. In order to facilitate the disassembly of the auxiliary rod 11; the horizontal rod 16 includes a protrusion and a compression spring (shown in the figure, not numbered) arranged inside the left end, and a U-shaped plate is arranged on the right side of the top of the vertical rod 10. A fixing hole is opened on the top plate of the U-shaped plate, and is used in conjunction with the protrusion and the compression spring. When the auxiliary rod 11 is disassembled, the protrusion is pressed to move it out of the fixing hole, and then the auxiliary rod 11 is held and rotated to the left to be disassembled (with Figure 4For example), during installation, the auxiliary rod 11 is rotated to the right. Since a compression spring is fixedly connected to the bottom of the protrusion, the U-shaped plate will automatically compress when it contacts the protrusion, and then slide into the fixing hole to complete the installation; like Figure 1-Figure 2 As shown, the upper surfaces of the positioning ring 1 8 and the positioning ring 2 9 are provided with a card slot, and the bottom ends of the vertical rod 10 and the auxiliary rod 11 are arranged inside the card slot through a rotating shaft, so that the vertical rod 10 and the auxiliary rod 11 can be conveniently rotated 90° to the left and right. When they are rotated 90° to the right, they can be conveniently retracted on the surface of the support rod 1 and the hydraulic support rod 2, which is convenient for carrying; like Figure 4 As shown, when the vertical rod 10 is in a vertical state, the driving block 14 is started to reverse (with the motor as the power source and electrically connected to the lithium battery 7), which can drive the screw 15 to rotate. At this time, the cross bar 16 moves downward on the surface of the screw 15. Since the left end of the cross bar 16 is connected to the auxiliary rod 11, when the cross bar 16 moves downward, it synchronously drives the hydraulic support rod 2 to move downward. At this time, the load-bearing rod 4 at its output end drives the cable 5 to move upward. When the driving block 14 rotates forward, the load-bearing rod 4 at its output end drives the cable 5 to move downward, which is convenient for removing or erecting the cable 5. Through the hydraulic support rod 2, the load-bearing rod 4 at one end thereof can be driven to extend and retract, so as to facilitate operation according to the use radius of the cable 5, which not only saves manpower but also improves work efficiency.

[0018] A threaded sleeve 17 is provided inside the support seat 3, and the left end of the threaded sleeve 17 is meshedly connected with a gear rod 18, the bottom end of the gear rod 18 extends to the inside of the support rod 1, and the right side of the bottom end is meshedly connected with a toothed plate 19, and the right end of the threaded sleeve 17 is fixedly connected to the adjustment seat 303, and the end of the toothed plate 19 close to the gear rod 18 is fixedly connected to an auxiliary belt 20, and the end of the auxiliary belt 20 away from the toothed plate 19 passes through the inner wall of the support rod 1 and is fixedly connected to the surface of the bottom end of the vertical rod 10, and the side of the toothed plate 19 away from the gear rod 18 is fixedly connected to a pressure plate 21.

[0019] like Figure 5-Figure 6 As shown, the threaded sleeve 17 includes an outer sleeve and an inner rod. A bevel gear is provided at the left end of the outer sleeve and is meshed with the top of the gear rod 18. The surface of the inner rod and the inner wall of the outer sleeve are provided with matching threads. When the outer sleeve rotates, the inner rod moves to the right, and synchronously drives the adjustment seat 303 to move to the right, thereby increasing the force-bearing area of ​​the support seat 3 and reducing the downward pulling force at both ends of the cable 5 when supporting. A passage for the auxiliary belt 20 to pass through is provided inside the support rod 1, so that the auxiliary belt 20 can be retracted inside. When the vertical rod 10 slowly rotates to the left to be in a vertical state, the auxiliary belt 20 drives the tooth plate 19 to move to the left, and synchronously drives the gear rod 18 to rotate. (At this time, the pressure plate 21 squeezes the spring 1 23 to make it in a compressed state.) Under the action of the threaded sleeve rod 17, the adjustment seat 303 is expanded to the right. When the vertical rod 10 moves to the right and shrinks on the surface of the support rod 1, the spring 23 releases the compressed state. Under the action of the pressure plate 21, the toothed plate 19 moves to the right and synchronously drives the gear rod 18 to rotate. At this time, under the action of the threaded sleeve 17, the adjustment seat 303 shrinks to the right side of the support seat 3.

[0020] A squeezing rod 22 is fixedly connected to one side of the pressure plate 21, a spring 23 is sleeved on the surface of the squeezing rod 22, the other end of the spring 23 is fixedly connected to the inner wall of the support rod 1, a compression chamber 24 is provided inside the support rod 1, a pressure sensor 29 is provided inside the compression chamber 24, and the other end of the squeezing rod 22 extends to the inside of the compression chamber 24.

[0021] A rubber layer 25 is provided on the outer wall of the support rod 1 near the compression chamber 24. A one-way valve 26, an electromagnetic valve 27, an air inlet 36 and an air outlet chamber 28 are provided inside the support rod 1, and the space is connected to the compression chamber 24 and the rubber layer 25. An exhaust hole is provided on the inner wall of the slot 301, and the hole is connected to the air outlet chamber 28.

[0022] like Figure 3 , Figure 4-Figure 5 As shown, there are two air inlet holes 36, one of which is provided on the surface of the support rod 1, near the exhaust end (point a) of the compression chamber 24; the other is provided on the inner wall of the compression chamber 24, near the extrusion rod 22 (point b); There are two one-way valves 26 in the above description. A one-way valve is provided at the connection between the air inlet hole at point a and the compression chamber 24 (only air can be introduced here, referred to as point c), and a one-way valve is provided at the compression chamber 24 near the rubber layer 25 (only air can be exhausted here, referred to as point d). When the pressing plate 21 drives the extrusion rod 22 to move to the left, the gas inside the compression chamber 24 is squeezed. At this time, the gas inside the compression chamber 24 enters the space where the rubber layer 25 is located, causing it to expand. At this time, the one-way valve at point c is not conducting, and the one-way valve at point d is conducting. When the threshold value set by the pressure sensor 29 is reached, the solenoid valve 27 is conducting, and the gas flows through the gas outlet chamber 28 and is discharged from the exhaust hole, which is convenient for cleaning the part where the arc plate 302 is located, reducing the dirt on the surface of the cable 5 from accumulating on the arc plate 302, and facilitating its cleaning; Among them, the pressure sensor 29, the air flow sensor and the solenoid valve 27 are electrically connected to the lithium battery 7; In order to facilitate the cleaning of the arc plate 302, an air flow sensor (shown in the figure, not numbered) is provided on the inner wall of the air outlet cavity 28. When the air flow is discharged and reaches the set threshold, the solenoid valve 27 is closed and is in a non-conducting state, and the discharge of the air flow is proportional to the pressure value of the pressure sensor 29.

[0023] The outer wall of the arc plate 302 is fixedly connected with a pressure column 31 , the other end of the pressure column 31 extends to the inside of the support seat 3 and is fixedly connected with a second spring 32 , and the other end of the second spring 32 is fixedly connected to the inner bottom wall of the support seat 3 .

[0024] like Figure 7 As shown, when the cable 5 is placed between the arc plates 302, due to its own specifications, the arc plates 302 compress the spring 2 32 through the pressure column 31, which facilitates adaptive adjustment of the support.

[0025] The electrical components mentioned above are all existing well-known technologies and are only cited here, and the specific structures are not described in detail.

[0026] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0027] In the present invention, the working steps of the device are as follows: When in use, the hydraulic support rod 2 is held in hand, and the load-bearing rod 4 is driven to be extended and retracted through the output end of the hydraulic support rod 2, so as to install or remove the cables 5 on its surface. According to the use requirements, the auxiliary rod 11 can be driven up and down by the driving component, so as to adjust the use position of the hydraulic support rod 2, so as to facilitate the work of assisting the installation and removal of the cables 5, which not only saves manpower but also improves work efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
