Description

Technical Field

[0001] This utility model belongs to the technical field of light pole installation equipment, and in particular relates to a light pole lifting auxiliary device. Background Technology

[0002] Generally, light poles longer than 15 meters are called high light poles or high mast lights. They are usually composed of tapered light poles and high-power combined light structures, and are used for large-area, high-brightness lighting needs.

[0003] During the installation of light poles, hoisting equipment is typically used to lift one end of the light pole and mount the light frame upwards to erect the pole. Then, workers hold the lower end of the pole to secure it in place. However, during the initial lifting process, the lower end of the pole may rub against the ground for a distance before it is fully lifted, which can affect the quality of the light pole. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a light pole lifting auxiliary device to prevent the light pole from scraping against the ground during the lifting process and to protect the light pole.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] A light pole lifting auxiliary device includes:

[0007] The base assembly includes a base plate with four legs at its bottom corners. Two legs on the same end of the base plate have T-slots on their opposite sides. Each leg has a roller at its lower end. A first hydraulic cylinder is located at one end of the top surface of the base plate, and a hinge seat is located at the other end. A support member is telescopically mounted on the bottom surface of the base plate. The support member includes a second hydraulic cylinder installed at the center of the bottom surface of the base plate. The output end of the second hydraulic cylinder has a pressure rod arranged along the length of the base plate. A crossbar is rotatably mounted at both ends of the pressure rod, and a support rod is rotatably mounted at both ends of the crossbar. The support rod is slidably mounted in the T-slot.

[0008] The connecting assembly includes a connecting plate, one bottom surface of which is rotatably connected to the output end of the first hydraulic cylinder, and the other two sides of the connecting plate are rotatably connected to the hinge seat. Two sets of locking fasteners are provided at intervals along the top surface of the connecting plate.

[0009] Furthermore, the roller is located on the outside of the T-slot.

[0010] Furthermore, the projection of the strut at the lower end of the outrigger is located on the outer circumference of the roller, and the length of the strut is greater than the diameter of the roller.

[0011] Furthermore, the two ends of the pressure bar are respectively provided with U-shaped seats with openings facing each other, and the middle part of the crossbar is provided with a protruding seat, which is rotatably mounted on the U-shaped seat.

[0012] Furthermore, the locking mechanism includes a set of symmetrically arranged clamps, the lower end of which is rotatably connected to the top surface of the connecting plate, and the upper ends of the same set of clamps are connected by locking bolts.

[0013] Furthermore, the height between the axis of rotational connection between the hinge seat and the connecting plate and the base plate is greater than the distance between the axis of rotational connection between the hinge seat and the connecting plate and the other end of the connecting plate.

[0014] Furthermore, two hinge seats are provided in parallel and spaced apart, and a notch is provided at the other end of the base plate. The notch is located between the two hinge seats, and the length of the notch is the same as the width of the connecting plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Secure the lower end of the light pole to the locking fastener, and use the rotating connecting plate to adapt to the angle between the light pole and the ground during the initial lifting of the light pole. Install rollers on the bottom surface of the base plate to isolate the light pole from the ground, effectively preventing the light pole from rubbing against the ground and affecting the quality of the light pole.

[0017] 2. The struts at both ends of the crossbar are slidably connected to the corresponding legs, thus adapting to uneven ground around the light pole installation area. When the connecting plate is perpendicular to the base plate, the side of the connecting plate away from the clamp is pressed tightly against the bottom of the notch groove, thereby ensuring the verticality of the light pole during installation and improving the installation quality.

Detailed Implementation

[0027] 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.

[0028] like Figures 1-7 This example provides a light pole lifting auxiliary device for hoisting high light poles longer than 15 meters. It is installed at the lower end of the light pole 1 to prevent the lower end of the light pole 1 from scraping against the ground during hoisting. The auxiliary device includes a base assembly 10 and a connecting assembly 20.

[0029] Specifically, such as Figures 2-5 As shown, the base assembly 10 includes a base plate 11, support legs 12, a first hydraulic cylinder 13, a hinge seat 14, and a support member 15. The base plate 11 has a rectangular plate structure. There are four support legs 12, which are respectively vertically downward at the four corners of the bottom surface of the base plate 11. Each support leg 12 has a roller 122 at its lower end. The roller 122 can be a universal wheel with a locking structure. A connecting seat is provided at the middle of one end of the top surface of the base plate 11. The bottom of the housing of the first hydraulic cylinder 13 is rotatably connected to the connecting seat through a connecting pin. The output end of the first hydraulic cylinder 13 is rotatably connected to one end of the connecting assembly 20. The hinge seat 14 is provided at the other end of the top surface of the base plate 11. Two hinge seats 14 are symmetrically provided on both sides of the long axis of the base plate 11. A notch 111 is recessed at the end of the base plate 11 where the hinge seat 14 is located. The notch 111 is located between the two hinge seats 14.

[0030] The support member 15 is located in the middle of the bottom surface of the base plate 11. The support member 15 includes a second hydraulic cylinder 151, a pressure rod 152, a crossbar 153, and a strut 154. The second hydraulic cylinder 151 is vertically installed at the center of the bottom surface of the base plate 11, and the output end of the second hydraulic cylinder 151 points vertically downward. The pressure rod 152 is located at the output end of the second hydraulic cylinder 151, and the length direction of the pressure rod 152 is consistent with the long axis direction of the base plate 11, so that the center of the short axis of the top surface of the pressure rod 152 is connected to the output end of the second hydraulic cylinder 151. U-shaped openings are provided vertically downward at both ends of the pressure rod 152. The base 1521 has two crossbars 153 located between two legs 12 on the same side of the base plate 11. The crossbars 153 are located at both ends of the pressure bar 152. The top surface of the middle part of the crossbar 153 protrudes upward to provide a boss 1531, which is located inside the U-shaped base 1521 and is rotatably connected to the U-shaped base 1521. Four support rods 154 are provided and are located at both ends of the corresponding crossbars 153. Openings are provided at both ends of the crossbars 153 so that the upper end of the support rod 154 is rotatably connected to the opening of the crossbar 153.

[0031] like Figures 3-7 As shown, the two legs 12 on the same side of the base plate 11 are respectively provided with T-shaped grooves 121 with a T-shaped cross section. One end of the vertical part of the T-shaped groove 121 is connected to the two legs 12 on the same side of the base plate 11. The cross section of the support rod 154 is T-shaped and is adapted to the T-shaped groove 121, so that the support rod 154 is slidably connected in the T-shaped groove 121. In order to avoid interference between the support rod 154 and the roller 122 when the lower end of the support rod 154 extends out of the lower end of the T-shaped groove 121 and rotates along the axis of the support leg 12, the projection of the support rod 154 on the cross section of the support leg 12 falls into the outer periphery of the rotation trajectory of the roller 122 around the axis of the support leg 12, and the length of the support rod 154 is greater than the diameter of the roller 122.

[0032] like Figures 1-3 As shown, the connecting assembly 20 includes a connecting plate 21 and a locking element 22. The connecting plate 21 has a rectangular plate structure, and its width is smaller than the opening width of the notch 111. The center of the bottom surface of one end of the connecting plate 21 is rotatably connected to the output end of the first hydraulic cylinder 13. The two sides of the other end of the connecting plate 21 are respectively rotatably connected to the corresponding hinge seats 14. The distance between the axis of rotation connecting the hinge seat 14 and the connecting plate 21 and the top surface of the bottom plate 11 is greater than the distance from the axis of rotation connecting the hinge seat 14 and the connecting plate 21 to one end of the connecting plate 21. This is so that when the first hydraulic cylinder 13 pushes the connecting plate 21 upward, after the connecting plate 21 rotates to a certain angle, interference between the axis of rotation connecting the hinge seat 14 and the connecting plate 21 and one end of the connecting plate 21 and the bottom plate 11 is avoided.

[0033] Two sets of locking fasteners 21 are provided at intervals along the long axis of the connecting plate 21 for connecting the lower outer wall of the lamp post 21. Each set of locking fasteners 22 includes two symmetrically arranged clamps 221. The lower end of the clamps 221 is rotatably connected to the top surface of the connecting plate 21, and the upper ends of the two clamps 221 in the same set of locking fasteners 22 are connected by locking bolts.

[0034] Specific usage process:

[0035] Using the output end of the hoisting equipment, place the lower end of the light pole 1, that is, the end of the light pole 1 that connects to the ground, between the clamps 221 of the two sets of locking fasteners 22, and use the locking bolts to lock the corresponding clamps 221. Then, remove the output end of the hoisting equipment and apply it to the upper end of the light pole 1 to carry out the hoisting operation, so that the light pole 1 is erected.

[0036] As the hoisting equipment moves upward, the first hydraulic cylinder 13 is activated, causing the first hydraulic cylinder 13 to push the connecting plate 21 to rotate upward around the connection between the connecting plate 21 and the hinge seat 14. The angle at which the first hydraulic cylinder 13 pushes the connecting plate 21 to rotate changes synchronously with the angle between the lamp post 1 and the ground as the hoisting equipment lifts the upper end of the lamp post 1 upward.

[0037] During the process of the light pole 1 being lifted by the hoisting equipment, the lower end of the light pole 1 moves towards the pile foundation position where the light pole 1 connects with the ground under the action of the roller 122, thereby avoiding the lower end of the light pole 1 from rubbing against the ground during the hoisting process, which would affect the quality of the light pole 1.

[0038] When the lamp post 1 is erected to a vertical position, the connecting plate 21 is perpendicular to the base plate 11, and the lower end of the connecting plate 21 is accommodated in the notch 111. To ensure the perpendicularity between the connecting plate 21 and the base plate 11, the distance between the bottom of the notch 111 recessed towards the center of the base plate 11 and the connecting line of the two hinge seats 14 is equal to half the thickness of the connecting plate 21. This ensures the verticality of the lamp post 1 after it is erected.

[0039] When the lower end of the light pole 1 moves above the pile foundation, the second hydraulic cylinder 151 is activated, causing the second hydraulic cylinder 151 to push the pressure rod 152 vertically downward. This causes the pressure rod 152 to drive the crossbar 153 downward, and then the crossbar 153 pushes the support rods 154 at both ends of the support rods 154 vertically downward, extending them beyond the lower end of the T-slot 121. The length of the support rods 154 extending beyond the lower side of the roller 122 is then increased. The hoisting equipment is then lowered vertically. At this time, workers need to hold the light pole 1 so that the lower end of the light pole 1 is aligned with the pile foundation and lowers downward. After descending to the predetermined height, the support rods 154 contact the ground. If there is uneven ground around the pile foundation, since the two ends of the support rods 154 and the crossbar 153 are rotatably connected, the extension length of each support rod 154 can be different to adapt to the uneven ground, thereby ensuring the verticality of the light pole 1 during installation and reducing the labor intensity of the workers.

[0040] Finally, loosen the locking bolts without removing them, only loosening the connection between the light pole 1 and the clamp 221, and then lower the lifting device so that the light pole 1 is vertically downward along the connection position of the pile foundation and connected to the pile foundation.

[0041] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
