[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] Example 1

[0023] See also Figure 1 to Figure 2 The utility model provides a clamping support device for a street light pole, which comprises a bottom plate 1, two groups of positioning frames 3 are symmetrically arranged on the bottom plate 1, and a positioning ring 301 for inserting the street light pole is fixedly arranged on the positioning frame 3, and a plurality of groups of positioning plates 308 for abutting against the outer end surface of the street light pole are arranged in a circumferential array on one side of the positioning ring 301, and each group of positioning plates 308 is connected to a driving mechanism that drives it to synchronously approach or move away from the ring center end; specifically, the positioning plates 308 in this embodiment are arranged in four groups in a circumferential array;

[0024] See also Figure 3-Figure 4The driving mechanism includes a limit plate 302 arranged in a circumferential array on the outer end surface of the positioning ring 301, a guide groove 303 is provided in the limit plate 302, a pin 403 is slidably embedded in the guide groove 303, an adjustment ring 4 is rotatably arranged on one side of the positioning ring 301, a plurality of groups of arc grooves 402 are provided in a circumferential array on the adjustment ring 4, the arc groove 402 extends from the proximal end to the distal end, one end of the pin 403 extends into the arc groove 402, and the other end is fixed to the push seat 304, and the push seat 304 is connected to the positioning plate 301 through a push rod 305. 08 is fixed; it can be explained that when the adjusting ring 4 is driven to rotate, it can drive the pin shaft 403 to slide in the guide groove 303 through the arc groove 402, and then drive each group of positioning plates 308 to synchronously approach the annular end through the push seat 304 and the push rod 305. When the street lamp pole is inserted into the positioning ring 301, each group of positioning plates 308 can be abutted against the outer end surface of the street lamp pole to achieve the positioning and fixing of the street lamp pole; the movement of each group of positioning plates 308 in this embodiment is synchronous, so that the positioning stability of the lamp pole is higher;

[0025] A screw rod 2 is also rotatably arranged on the base plate 1, and the end of the screw rod 2 is fixed to the output end of the first motor 203. The threads on both sides of the screw rod 2 rotate in opposite directions. A nut 201 fixed to the positioning frame 3 is symmetrically spirally sleeved on the screw rod 2. It can be explained that when positioning street light poles of different lengths, the screw rod 2 is first driven to rotate by the first motor 203 based on the length of the street light pole. During the movement of the nut 201 on the screw rod 2, the positioning frame 3 is synchronously driven to move closer to or away from each other, thereby realizing the adjustment of the positioning position of the street light pole, so that the clamping stability of the street light pole is higher.

[0026] Two groups of guide rods 202 are symmetrically arranged on the base plate 1, and both ends of the positioning frame 3 are slidingly connected to the guide rods 202 respectively; it can be explained that by arranging the guide rods 202 on both sides of the screw 2, the positioning frame 3 can have higher movement stability when being transported by the nut 201.

[0027] Furthermore, in order to prevent the adjustment ring 4 from being separated from the pin 403, in this embodiment, a limiting protrusion 404 is provided at the end of the pin 403;

[0028] Example 2

[0029] On the basis of Example 1, a positioning seat 307 is fixedly arranged on one side of each group of guide grooves 303, and a push rod 305 can be slidably inserted in the positioning seat 307, wherein a return spring 306 is also arranged on the push rod 305, one end of the return spring 306 is fixed to the push seat 304, and the other end is fixed to the positioning seat 307; it can be explained that when each group of positioning plates 308 is driven to move inward through the arc groove 402, the push rod 305 squeezes the return spring 306 to contract and generate elastic force, and when the adjustment ring 4 rotates in the opposite direction, the return spring 306 can synchronously drive each group of positioning plates 308 to move away from each other, based on this, the street lamp pole can be disassembled, and the operation is very convenient;

[0030] A gear ring 401 is arranged on the outer end surface of the adjusting ring 4, wherein the gear ring 401 meshes with the gear 501, the gear 501 on one side is fixedly connected to the sleeve 502, and the gear 501 on the other end is fixedly connected to a telescopic rod 503 slidably plugged with the sleeve 502, and a plurality of groups of strip-shaped card slots are arranged in a circumferential array on the inner end surface of the sleeve 502, and a plurality of groups of strip card seats 504 correspondingly arranged on the outer end surface of the telescopic rod 503 are engaged with the strip card slots; the gear 501 on one side is fixed to the output end of the second motor 5; specifically, one side of the second motor 5 is fixed to the positioning plate 308 through the mounting plate, and the gear 501 on the other side is rotatably connected to the frame, and the frame is fixed to the positioning plate 308; in this embodiment, when the gear 501 on one side is driven to rotate, the strip card slots and the strip card seats 504 between the sleeve 502 and the telescopic rod 503 can be synchronously driven to rotate;

[0031] The working principle of a clamping support device for a street light pole provided by the utility model is as follows: when positioning street light poles of different lengths, firstly, based on the length of the street light pole, the screw rod 2 is driven to rotate by the first motor 203, and the nut 201 synchronously drives the positioning frame 3 to move closer or farther away from each other during the movement on the screw rod 2, thereby realizing the adjustment of the positioning position of the street light pole. When the adjustment ring 4 is driven to rotate, it can drive the pin shaft 403 to slide in the guide groove 303 through the arc groove 402, and then can drive each group of positioning plates 308 to synchronously approach the annular end through the push seat 304 and the push rod 305. When the street light pole is inserted into the positioning ring 301, each group of positioning plates 308 can be abutted against the outer end surface of the street light pole to realize the positioning and fixation of the street light pole.
