[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Please see Figures 1-7 This invention provides an auxiliary device for installing utility poles, including a trailer 1; a notch 2 is provided on the trailer 1; support columns 3 are provided at the middle of both sides of the notch 2; a connecting rod 4 is fixedly connected between the tops of the support columns 3; a guide wheel 5 is rotatably connected to the connecting rod 4; a wire rope 6 is rotatably connected to the guide wheel 5; a clamping assembly is fixedly connected to the bottom end of the wire rope 6, and the clamping assembly is used to clamp the utility pole; a fixing assembly is provided at the end of the trailer 1 near the support columns 3, and the fixing assembly is used to support the utility pole; in order to achieve the purpose of lifting the utility pole and assisting the operator in installing the utility pole, in specific operations, the trailer 1 is first moved to the position of the utility pole, and then the clamping assembly is lowered by the cooperation of the wire rope 6, the connecting rod 4 and the guide wheel 5. Under the action of the operator, the clamping assembly clamps the upper middle part of the utility pole, and then the wire rope 6 drives the clamping assembly to lift it. The system lifts the pole, assisting workers in its installation. By replacing manual labor, the pole installation is completed mechanically, saving manpower and improving efficiency. Furthermore, poles are difficult to move due to their weight. The conventional method involves placing the pole on a trolley, which is then moved by a drive vehicle. However, loading the pole onto the trolley requires pry bars, which is cumbersome. By moving the trailer 1 above the pole, clamping components hold the pole, raising one end to the top of the trailer 1, and then using fixing components to support the tail of the pole, the pole is parallel to the trailer 1, thus achieving the goal of transporting the pole. This not only facilitates pole installation but also transportation, further improving work efficiency.

[0031] Furthermore, such as Figure 1 and Figure 4 As shown, the clamping assembly includes clamping arms 61; two clamping arms 61 are provided, and the two clamping arms 61 are hinged together in the middle; a first connecting block 63 is fixedly connected to the top of each clamping arm 61, and the clamping arm 61 is fixedly connected to the wire rope 6 via the first connecting block 63; a clamping claw 62 is fixedly connected to the bottom of each clamping arm 61, and the clamping claws 62 are arranged opposite to each other. In order to achieve the purpose of clamping and fixing the pole, two clamping arms 61 are provided that are hinged together. The upper part of the clamping arm 61 is connected to the wire rope 6 via the connecting block, and the lower part of the clamping arm 61 is connected to the pole via the clamping claw 62. When the wire rope 6 retracts and drives the pole to rise, since the clamping arm 61 is in a hinged state and is subjected to the gravity of the pole and the clamping claw 62, the wire rope 6 is in a taut state. When the wire rope 6 rises, it will drive the upper ends of the clamping arms 61 to move closer together, which will cause the lower ends of the clamping arms 61 to move closer together as well, so that the pole is clamped by the clamping claw 62. The purpose of removing the clamping assembly is to simultaneously apply a force opposite to that of the wire rope 6 to the clamping arm 61 by the pole's own weight and the cooperation of the clamping claws 62, causing the two clamping arms 61 to move closer together. The greater the weight of the pole, the tighter the clamping force of the clamping claws 62, and the higher the stability of the clamping. When it is necessary to separate the clamping assembly from the pole, simply connect the pole to the ground, the wire rope 6 is in a slack state, and the clamping claws 62, the weight of the pole itself, and the reaction force exerted on it by the ground cancel each other out. At this time, the two clamping claws 62 are relaxed, and the purpose of removing the clamping assembly can be achieved.

[0032] Furthermore, such as Figure 6 and Figure 7 As shown, the fixing component includes a support block 10; there are two support blocks 10, which are arranged opposite to each other; a circular hole 103 is provided at the outer end of the support block 10; a groove 101 is provided on the trailer 1 at the position corresponding to the support block 10; a fixing rod 102 is fixedly connected in the groove 101, and the support block 10 is rotatably connected in the groove 101 through the cooperation of the circular hole 103 and the fixing rod 102. To facilitate the transportation of the utility pole, a trough 101 is provided at the rear of the trailer 1. Symmetrically arranged support blocks 10 are hinged within the trough 101 via a fixing rod 102. When the clamping assembly lifts the utility pole to the upper surface of the trailer 1, one of the support blocks 10 is first lowered, and then the end of the utility pole is placed on the support block 10 using the lever principle. Then, the other support block 10 is also lowered, so that the ends of the two support blocks 10 fit together, thereby achieving the purpose of simultaneously lifting and supporting both ends of the utility pole, completing the preparatory work before transportation. When installing the utility pole, the above operation is reversed, and the utility pole is continued to be lifted using the steel wire rope 6 and the clamping assembly.

[0033] Furthermore, such as Figure 1 and Figure 2As shown, the upper part of the side of the support column 3 and the upper surface of the trailer 1 are respectively fixedly connected to the first hinge block 31; the first hinge block 31 is rotatably connected to the third hinge block 34; the corresponding third hinge blocks 34 are respectively fixedly connected to the first telescopic cylinder 32, and the upper part of the support column 3 is connected to the trailer 1 through the first telescopic cylinder 32; the upper surface of the trailer 1 is respectively fixedly connected to the position corresponding to the bottom of the support column 3, and the support column 3 is rotatably connected to the trailer 1 through the second hinge block 33. To facilitate the movement of the trailer 1, prevent it from being unable to pass through height-restricted areas, and facilitate its placement in the garage when it stops working, a second hinge block 33 is installed on the trailer 1 and rotatably connected to the support column 3. A first hinge block 31, a third hinge block 34, and a first telescopic cylinder 32 are installed on the surface of the trailer 1 and above the support column 3 for connection. By controlling the second telescopic cylinder 111, the support column 3 can be rotated around the second hinge block 33. Before or after operation, the other end of the support column 3 is lowered, reducing its height. During operation, the other end of the support column 3 is raised to assist in the installation of the utility pole. Furthermore, when installing the utility pole, the angle of the support column 3 can be controlled by controlling the second telescopic cylinder 111 to further adjust the position of the hoisted utility pole, so that the utility pole can be smoothly inserted into the pole pit.

[0034] Furthermore, such as Figure 3 As shown, each of the support columns 3 has a sliding groove 11 on its side near the support block 10; a second telescopic cylinder 111 is fixedly connected to the top of each sliding groove 11; a slider 112 is fixedly connected to the output end of each second telescopic cylinder 111, and the slider 112 slides within the sliding groove 11; a fixed shaft 113 is fixedly connected between the sliders 112; a sleeve 114 is rotatably connected to the fixed shaft 113. This arrangement is to maintain the stability of the pole during transportation and to facilitate the insertion of the pole into the pole pit after lifting.

[0035] When the pole is short, the clamping assembly clamps the upper middle part of the pole, causing it to tilt after lifting and stand above the pole pit, which is inconvenient for pole installation. To keep the pole as vertical as possible during installation, making it easier to insert it into the pole pit, the trailer 1 is moved first to align the clamps with the pole pit, ensuring that after lifting, the pole is vertical and its bottom is above the pole pit. Then, the clamps are controlled to slowly lift one end of the pole, and as the pole is lifted, the second telescopic cylinder 111 drives the slider 112 to descend continuously. At this time, the upper part of the pole is lifted by the clamp 62, tending to be vertical, but it is still tilted after being fully lifted. Finally, the lower part of the pole is limited by the sleeve 114, and in conjunction with the clamp 62, the pole is in a relatively vertical state, allowing the pole to be installed in the pit.

[0036] When the pole is long, firstly, move the trailer 1 until the middle of its rear end is aligned with the pole pit. Then, use the second telescopic cylinder 111 to move the slider 112 to the top of the slide groove 11, preventing the sleeve 114 from interfering with the pole lifting. Next, use the gripper 62 to lift one end of the pole to a certain height and align the other end with the pole pit. Continue to use the gripper 62 to lift the end of the pole that is not inserted into the pole pit. When it is lifted to a certain height, move the trailer 1 towards the pole pit, and the lower end of the pole will be further lifted. Once the pole is lowered into the pit, the above operations are repeated and adjustments are made to allow the pole to be in one of two states: standing upright or tilted within the pit. If the pole is standing upright, subsequent pit-laying and fixing operations can be carried out directly. If the pole is tilted within the pit, the clamp 62 can be removed from the pole, and the sleeve 114 located at the top of the pole can be moved by the trailer 1 to apply force to the upper end of the pole, adjusting the tilted state of the pole within the pit. After adjustment, subsequent pit-laying and fixing operations can be carried out.

[0037] Before transporting the utility pole, the pole is kept parallel to the trailer 1 with the cooperation of the support column 3 and the clamping assembly. At this time, the second telescopic cylinder 111 drives the slider 112 to descend, and the sleeve 114 presses down the pole. The clamp 62 lifts the pole to achieve force balance, which can fix the pole and improve stability.

[0038] Furthermore, such as Figure 1 and Figure 4 As shown, a first fixed frame 7 is fixedly connected to the upper surface of the trailer 1; a winding roller 8 is rotatably connected to the first fixed frame 7, and the other end of the wire rope 6 is wound and connected to the winding roller 8; a reciprocating motor 9 is provided at the end of the winding roller 8, and the output end of the reciprocating motor 9 is fixedly connected to the end of the winding roller 8. In order to perform winding and unwinding operations on the wire rope 6, the trailer 1 is provided with a first fixed frame 7 and a reciprocating motor 9. The reciprocating motor 9 controls the rotation of the winding roller 8, and then the winding roller 8 winds up the wire rope 6.

[0039] Furthermore, such as Figure 1 and Figure 7 As shown, a second connecting block 15 is fixedly connected to the middle of the end of the trailer 1 away from the cut 2; a double-headed connecting block 16 is rotatably connected to the second connecting block 15; a pin 17 is provided on the second connecting block 15, and the second connecting block 15 is rotatably connected to the double-headed connecting block 16 via the pin 17. To facilitate the movement of the trailer 1, a second connecting block 15 is provided at the front of the trailer 1 for easy connection to the power vehicle. Simultaneously, the double-headed connecting block 16 and the pin 17 facilitate the power vehicle to drive the trailer 1 to perform larger-angle turning operations, improving flexibility.

[0040] Furthermore, such as Figure 2 and Figure 5As shown, a second fixing frame 12 is fixedly connected to the upper surface of the trailer 1 at the position between the cut 2 and the first fixing frame 7; two shafts 13 are fixedly connected to the top of the second fixing frame 12, and the shafts 13 are located on both sides of the wire rope 6; each shaft 13 is rotatably connected to a limiting pulley 14. In order to ensure that the wire rope 6 on the winding roller 8 is always on the same plane as the guide wheel 5 during the winding and unwinding process, and to avoid the wire rope 6 from deviating to the side, a second fixing frame 12 is set on the trailer 1, and the wire rope 6 is restricted to the middle by the cooperation of the limiting pulley 14 and the shaft 13, so as to ensure that the position of the wire rope 6 will not shift.

[0041] Furthermore, such as Figure 3 and Figure 6 As shown, the upper part of the support block 10 is wedge-shaped; a fixed pulley 115 is fixedly connected to the middle of the sleeve 114. To ensure the pole is fixed in the middle of the trailer 1 during transport, the upper part of the support block 10 is wedge-shaped, allowing the pole to automatically slide to the bottom of the wedge-shaped support block 10, i.e., the middle of the trailer 1, under its own weight. To prevent displacement during pole installation when limited by the sleeve 114, a fixed pulley 115 is fixedly connected to the middle of the sleeve 114. Since the wedge-shaped support block 10 already positions the pole in the middle of the trailer 1, the surface of the pole will automatically contact the fixed pulley when it is lifted and erected. The concave part of 115 fits snugly, and because the fixed position of the fixed pulley 115 on the sleeve 114 is fixed, the stability of the pole body when it is lifted and erected is improved under the restriction of the fixed pulley 115. Furthermore, under the action of the sleeve 114, the fixed pulley 115 can rotate as the pole body is lifted, reducing the wear between the pole body and the sleeve 114. Moreover, when transporting the pole, placing the pole inside the fixed pulley 115 can further improve the stability of the pole during transportation.

[0042] Furthermore, such as Figure 2 and Figure 5 As shown, the bottom of the second fixing frame 12 is an isosceles triangle; the middle of the limiting pulley 14 is concave, and the limiting pulleys 14 are circular and fit together. In order to improve the stability of the second fixing frame 12 and ensure the limiting effect of the limiting pulleys 14 on the wire rope 6, the bottom of the second fixing frame 12 is set as an isosceles triangle, which has better stability. The middle of the limiting pulleys 14 is set as concave. After the two limiting pulleys 14 are fitted together, the gap in the middle fits with the wire rope 6. The wire rope 6 is restricted between the limiting pulleys 14 and rotates as the wire rope 6 is contracted and unloaded.

[0043] Working principle:

[0044] First, trailer 1 is moved to the position of the utility pole. Then, the clamping assembly is lowered by the cooperation of wire rope 6, connecting rod 4, and guide wheel 5. Under the operator's guidance, the clamping assembly clamps the upper middle part of the pole. Then, wire rope 6 drives the clamping assembly to lift, raising the pole upwards. This assists the operator in installing the pole. By replacing manual labor with machinery, the pole installation work can be completed, saving labor and improving efficiency.

[0045] Meanwhile, due to their considerable weight, utility poles are difficult to move. The conventional method is to place the poles on a trolley, which is then moved by a drive vehicle to achieve the purpose of transportation. However, when loading the poles onto the trolley, a pry bar is required for assistance, which is quite cumbersome. By moving the trailer 1 above the pole to be transported, clamping components are used to hold the pole, and one end of the pole is raised to the upper surface of the trailer 1. Then, the tail of the pole is supported by a fixing component, so that the pole and the trailer 1 are in a parallel state, thus achieving the purpose of transporting the pole. This not only facilitates the auxiliary installation of the poles but also facilitates the transportation of the poles, further improving work efficiency.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
