DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] This embodiment includes a rectangular support frame 1. Since the foundation of street lamps is mostly constructed in the road green belt, the rectangular support frame 1 can span the curbstones on both sides of the road green belt, that is, the length of the rectangular support frame 1 is greater than the distance between the curbstones on both sides of the road green belt. The four corners of the rectangular support frame 1 are provided with support legs 2 downward, and the bottom of the support legs 2 is installed with rollers 3. The rollers 3 have a braking function, and the device can be pushed to move along the roads on both sides of the green belt through the rollers 3. In order to further increase the stability of the device, it is preferred that an oblique support rod 16 is provided between the rectangular support frame 1 and the support legs 2.

[0016] Two horizontal middle support rods 4 are provided in the middle of the rectangular support frame 1 along the width direction of the rectangular support frame 1. The two middle support rods 4 are parallel. A long hole 5 is provided on the middle support rod 4 along the length direction of the middle support rod 4. The long hole 5 penetrates the middle support rod 4 downward. Two vertical sleeves 6 are slidably provided in the long hole 5, that is, the sleeve 6 can slide in the long hole 5. The sleeve 6 has an internal thread, and the internal thread of the sleeve 6 is connected to a long bolt 7. The upper part of the bolt 7 is threadedly connected to a counterweight block 8. A nut is provided at the lower part of the bolt 7, and the nut is not drawn in the accompanying drawings. The counterweight block 8 is used to prevent the entire device from floating up when pouring concrete. In this embodiment, the counterweight block 8 adopts a cylindrical block, and an internal threaded hole penetrating the cylindrical block is provided in the middle of the cylindrical block, and the cylindrical block is screwed onto the bolt 7 through the internal threaded hole.

[0017] Connecting ears 9 are provided on both sides of the upper end of the sleeve 6, and fixing holes 10 are provided on the connecting ears 9. A plurality of adjustment holes 11 corresponding to the fixing holes 10 are provided on the upper surface of the middle support rod 4 on both sides of the long hole 5. The fixing hole 10 is aligned with any adjustment hole 11, and screws can be screwed into the fixing holes 10 and the adjustment holes 11 to fix the sleeve 6 on the middle support rod 4.

[0018] This embodiment also includes a fixing plate 12, which is used to fix the embedded parts of the street lamp foundation. Connection holes 13 are symmetrically provided at the four corners of the fixing plate 12, and the connection holes 13 are used to connect with the rectangular support frame 1. The bolts 7 on the rectangular support frame 1 pass downward through the connection holes 13, and then the fixing plate 12 and the bolts 7 are fixed together by the nuts at the bottom of the bolts 7. In order to better fasten the fixing plate 12 and the bolts 7 together, it is preferred to provide a pad 17 at the bottom of the bolts 7, and the pad 17 is located on the upper surface of the fixing plate 12, so that when tightening the lower end nuts, the fixing plate 12 and the bolts 7 can be better fixed together.

[0019] A threading hole 14 is provided in the middle of the fixing plate 12, and the threading hole 14 is used to pass the pipeline of the embedded part. A plurality of round holes 15 are provided around the threading hole 14, and the round holes 15 are used to pass the anchor bolts 7 of the embedded part. The number and size of the central through hole 14 and the round hole 15 on the fixing plate 12 vary according to the embedded part.

[0020] Usage process: First, let the anchor bolt 7 of the embedded part pass through the round hole 15 of the fixed plate 12 from bottom to top, and then screw the nut on the upper part of the anchor bolt 7, tighten the nut to fix the anchor bolt 7 on the fixed plate 12, and then pass the pipeline through the threading hole 14 in the middle of the fixed plate 12 and fix it, place the fixed plate 12 and the embedded part in the foundation pit hole, and then push the rectangular support frame 1 to the foundation of the street lamp outside the curb, adjust the position of the rectangular support frame 1, and then slide the sleeve 6 to adjust the four bolts 7 to correspond to the connecting holes 13 at the four corners of the fixed plate 12, and then screw the screws into the fixing holes 10 on the sleeve 6 and the adjustment holes 11 of the middle support rod 4 to fix the sleeve 6 on the middle support rod 4, and then screw the sleeve 6 in Bolt 7 adjusts the height of the lower end of bolt 7. The height of the lower end of bolt 7 determines the height of fixed plate 12, and then determines the buried depth position of embedded parts on fixed plate 12. After adjustment according to design requirements, pass the connecting hole 13 of fixed plate 12 through the lower end of bolt 7, and then tighten the nut at the lower part of bolt 7 to fix fixed plate 12 and bolt 7 together. At this point, the embedded parts are fixed together with fixed plate 12, and fixed plate 12 is fixed together with rectangular support frame 1. In the early stage, the embedded parts are adjusted to the designed position by adjusting the height of bolt 7. Finally, the counterweight block 8 can be screwed on the top of bolt 7. When pouring concrete in the foundation pit later, the counterweight block 8 can prevent the device from floating, thereby ensuring that the position of the embedded parts is not offset. The concrete pouring is divided into two steps. After the first step of pouring, the concrete pouring position is located below the fixed plate 12, but the lower part of the embedded part has been poured in the concrete. After the concrete poured in the first step solidifies, the nut at the bottom of the bolt 7 and the nut on the anchor bolt 7 can be unscrewed, and then the entire device can be taken out from above the embedded part, and then the second step of pouring can be carried out.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
