Description

Technical Field

[0001] This application belongs to the field of light pole installation technology, and in particular relates to a straightening device for light pole installation. Background Technology

[0002] When installing light poles, a crane is first used to lift the light poles to a position perpendicular to the installation ground, and then the light poles are lowered vertically for connection and installation. However, the light poles are always swaying when lifted, and multiple people are needed to hold the light poles to keep them vertical during installation. This installation method is cumbersome and cannot effectively fix the light poles, thus failing to ensure that the light poles are perpendicular to the ground. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides a straightening device for lamp post installation, which can effectively fix the lamp post and simplify the installation process.

[0004] To achieve the above objectives, the present invention employs the following technology: A straightening device for installing light poles, comprising: The first circular tube has a first notch arranged along its length in its tube wall, and the first notch passes through the upper and lower ends of the first circular tube; the outer wall of the first circular tube has at least one ratchet rack arranged along its length. A clamping mechanism is provided at the upper end of the first circular tube to clamp the lamp post and make the lamp post axis coincide with the axis of the first circular tube; The second circular tube is coaxially arranged with the first circular tube, and the first circular tube slides within the second circular tube along its own axis. The second circular tube has a second notch arranged along its length, which passes through the upper and lower ends of the second circular tube. The first and second notches face the same direction. The upper end of the second circular tube is rotatably equipped with levers of the same number as the ratchet racks, and each lever has a pawl at its end. The rotation axis of the lever is perpendicular to the axis of the second circular tube, and an elastic element is provided at its rotation axis to direct the lever toward the upper end of the second circular tube and to abut each pawl against the corresponding ratchet rack. A circular ring is coaxially positioned below the second circular tube and spaced at a predetermined distance from it. The radius of the circular ring is larger than that of the second circular tube. Multiple ground-embedded rods are vertically and slidably inserted through the top surface of the circular ring and arranged in a circumferential array around the axis of the circular ring. A third notch is opened on the circular ring, which penetrates the inner and outer sides of the circular ring. The orientation of the third notch is the same as that of the second notch.

[0005] The beneficial effects of this utility model are as follows: 1. By setting up the first round tube and the clamping mechanism, the lamp post axis can be made to coincide with the first round tube axis while clamping the lamp post, thereby positioning the lamp post in a vertical state and simplifying the installation method of the lamp post; 2. By setting up the first and second round tubes and fixing the ring with the ground rod, the light pole remains vertical during the lowering process, effectively avoiding shaking and displacement, and has high installation stability. 3.

Detailed Implementation

[0011] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0012] This application provides a straightening device for lamp post installation, such as... Figures 1-4 As shown, it includes: a first circular tube 1, a clamping mechanism 2, a second circular tube 3, a ring 4, etc.

[0013] Among them, such as Figures 1-3 As shown, the first circular tube 1 has a first notch 11 arranged along its length on its tube wall. The first notch 11 passes through the upper and lower ends of the first circular tube 1. The width of the first notch 11 is greater than the diameter of the lamp post. The outer tube wall of the first circular tube is provided with at least one ratchet 12 arranged along its length. In this embodiment, the number of ratchet 12 is one.

[0014] like Figures 1-3As shown, two threaded holes are opened through the outer wall of the upper end of the first circular tube 1 into the tube. The axes of the two threaded holes coincide and intersect perpendicularly with the axis of the first circular tube 1. The two threaded holes are located on both sides of the first notch 11. The clamping mechanism 2 includes two screws 21 that are threaded into the corresponding threaded holes and two V-blocks 22. The two V-blocks 22 are arranged opposite to each other. The ends of the two screws 21 located in the first circular tube 1 rotate on the back of the corresponding V-blocks 22. A pair of guide rods 23 arranged in the same direction as the screws 21 are provided on the back of the V-blocks 22. The guide rods 23 slide through the tube wall of the first circular tube 1, and the screws 21 are located between the two guide rods 23.

[0015] like Figures 1-4 As shown, the second circular tube 3 is coaxially arranged with the first circular tube 1, and the first circular tube 1 slides within the second circular tube 3 along its own axis. The second circular tube 3 has a second notch 35 arranged along its length on its wall, which extends through the upper and lower ends of the second circular tube 3. The width of the second notch 35 is greater than the diameter of the lamp post. The first notch 11 and the second notch 35 face the same direction. A lever 31 is rotatably provided at the upper end of the second circular tube 3, and a pawl 32 is provided at its end. The rotation axis of the lever 31 is perpendicular to the axis of the second circular tube 3, and an elastic element 33 is provided at its rotation axis. Specifically, the elastic element 33 can be a spring sheet, a torsion spring, etc. In this embodiment, a spring sheet is used, and its two ends are respectively connected between the inner side of the lever 31 and the upper end face of the second circular tube 3. When the spring sheet is in its natural state, the lever 31 faces the upper end of the second circular tube 3, and the pawl 32 abuts against the ratchet rack 12.

[0016] like Figures 1-4 As shown, the ring 4 is coaxially positioned below the second circular tube 3 and spaced at a predetermined distance from it. The radius of the ring 4 is larger than the radius of the second circular tube 3. The ring 4 and the lower end of the second circular tube 3 are connected by multiple supports 43, which are arranged in a circular array around the axis of the ring 4. Three ground-mounted rods 41 are vertically and slidably inserted on the top surface of the ring 4 and are arranged in a circular array around the axis of the ring 4. A third notch 42 is provided on the ring 4, which penetrates the inner and outer sides of the ring 4. The width of the third notch 42 is larger than the diameter of the lamp post, and the orientation of the third notch 42 is the same as that of the second notch 35.

[0017] When in use, place the ring 4 flat on the ground, adjust the position of the ring 4 so that the mounting base of the lamp post is located in the center of the ring 4, and then embed the three ground-mounting rods 41 into the ground to fix the device. At this time, the axes of the first round tube 1, the second round tube 3, and the ring 4 are collinear and perpendicular to the ground, and the pawl 32 is engaged between the teeth of the ratchet rack 12. Figures 1-3 As shown, the lamp post is hoisted to a roughly vertical position so that it can enter the first round tube 1 and the second round tube 3; the lamp post is moved so that it enters the first round tube 1 and the second round tube 3 through the first notch 11 and the second notch 35, with the base of the lamp post located below the lower end face of the second round tube 3.

[0018] like Figures 1-3 As shown, the operator screws in two screws 21. Correspondingly, a scale can be set between the screws 21 and the first round tube 1 to ensure that the two screws 21 are screwed in to the same length when the operator screws in. As the screws 21 move, the two V-blocks 22 move closer to each other. Since the thread helix angle is less than the friction angle when the screws 21 are engaged with the threaded hole, the screws 21 have self-locking properties, which allows the two V-blocks 22 to clamp the lamp post as the screws 21 move. At the same time, due to the structure of the V-blocks 22 and the fact that the two screws 21 are screwed in to the same length, the lamp post is clamped so that its axis is coaxial with the axis of the first round tube 1. That is, the lamp post is fixed and perpendicular to the ground at this time.

[0019] like Figure 1 and Figure 2 As shown, the crane is operated so that the weight of the light pole is borne by the crane. The lever 31 is rotated outwards, causing the pawl 32 to disengage from the teeth of the ratchet rack 12. At this point, the first round tube 1 is allowed to slide along the axis. The crane slowly lowers the light pole, with the V-block 22 maintaining its clamping position. The light pole, V-block 22, and first round tube 1 move downwards synchronously. Due to the sliding fit between the first round tube 1 and the second round tube 3, the light pole remains vertical throughout its descent until the mounting base of the light pole aligns with the ground base. The operator then installs the mounting base onto the ground base, completing the installation of the light pole. The operator then reverses the screw 21, causing the V-block 22 to separate towards each other and pull out the grounding rod 41. The device is then moved, allowing the light pole to move out of the first notch 11, the second notch 35, and the third notch 42, thus completing the separation of the device from the light pole. By setting the first round tube 1 and the two V-shaped blocks 22, the lamp post axis can be made to coincide with the axis of the first round tube 1 while clamping the lamp post, thereby positioning the lamp post in a vertical state and simplifying the installation method of the lamp post; and by setting the first round tube 1 and the second round tube 3, and cooperating with the ground rod 41 to fix the ring 4, the lamp post remains vertical during the lowering process, effectively avoiding shaking and displacement, and has high installation stability.

[0020] Specifically, such as Figure 4 As shown, a receiving groove 34 is provided on the upper end face of the second circular tube 3 along its length direction. When the first circular tube 1 slides along the axis, the ratchet 12 can enter the receiving groove 34 to avoid motion interference.

[0021] Preferred, such as Figure 1 As shown, the lower end of the ground anchor 41 is set in a pointed cone shape so that the ground anchor 41 can be embedded into the ground.

[0022] Specifically, such as Figure 3 As shown, two guide blocks 13 are provided on the outer wall of the lower end of the first circular tube 1, and the two guide blocks 13 are arranged in a circular array around the axis of the first circular tube 1; as Figure 4As shown, the inner wall of the second circular tube 3 has two guide grooves 36 arranged along its length, and the guide block 13 is slidably fitted in the corresponding guide groove 36.

[0023] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
