[0023] The utility model provides a technical scheme of:
[0024] The concrete pole tip head structure includes a head body 1, a sliding groove 4 is formed in the upper end of the head body 1, and a cover plate 2 is clamped at the position; the cover plate 2 is made of composite material; a sliding groove 4 is formed in the head body 1; two groups of adjusting grooves 13 are formed in the sliding groove 4; connecting rods are fixedly connected in the two groups of adjusting grooves 13; the end portions of the connecting rods are fixedly connected with sliding plates 8; a plurality of slide rods 10 are slidably connected to the outer walls of the two groups of sliding plates 8; the end portions of the plurality of slide rods 10 are fixedly connected with clamping plates 9; the inner and outer walls of the clamping plates 9 and the sliding plates 8 are arc-shaped; elastic mechanisms are arranged on the outer walls of the slide rods 10; and drive assemblies for driving the two groups of clamping plates 9 to slide are installed in the sliding groove 4.
[0025] Specifically, the two groups of clamping plates 9 apply radial clamping force from the inside of the pole, avoiding the damage to the pole structure caused by the traditional external screw fixing mode, and completely eliminating the problem of water seepage through the screw holes.
[0026] The elastic mechanism includes limit blocks 11 fixed to the end portions of the slide rods 10; the outer walls of the limit blocks 11 are sleeved with springs 12; one end of each spring 12 is fixedly connected with a limit block 11; and the other end of each spring 12 is fixedly connected with the outer wall of a sliding plate 8.
[0027] Specifically, the combination of the limit blocks 11 and the springs 12 provides a certain elastic pre-tightening force, so that the clamping plates 9 can tightly adhere to the inner wall of the pole.
[0028] The drive assembly includes two groups of toothed plates 6 slidably connected in the sliding groove 4; and the two groups of connecting rods are fixedly connected to the lower end faces of the two groups of toothed plates 6.
[0029] Specifically, the sliding of the two groups of toothed plates 6 can synchronously drive the two groups of sliding plates 8 to slide towards or away from each other, ensuring that the clamping force of the clamping plates 9 on the inner wall of the pole is uniformly distributed, avoiding unilateral overload and affecting the stability of the device after overall installation.
[0030] A gear 5 is rotatably connected in the sliding groove 4, and the gear 5 is engaged with the two groups of toothed plates 6; a rotating block 3 is rotatably connected in the sliding groove 4; the radius size of the limiting block 11 is greater than that of the sliding rod 10; two groups of limiting rods 7 are fixedly connected to the inner wall of the sliding groove 4; the two groups of toothed plates 6 are slidingly connected to the outer wall of the two groups of limiting rods 7 respectively; the outer wall of the limiting rod 7 is square; and the sliding groove 4 is coaxially fixedly connected with the gear 5.
[0031] In specific use, the working principle of the utility model is as follows:
[0032] When the operator first places the head body 1 above the top of the electric pole, ensures that the inner wall of the lower end of the head body 1 is aligned with the outer wall of the electric pole, at this time, the clamping plate 9 is in the initial state, located in the inner cavity of the electric pole, and does not exert pressure on the inner wall of the electric pole. Then the operator rotates the rotating block 3, drives the gear 5 to rotate, drives the two groups of toothed plates 6 to slide to the two sides, drives the sliding plate 8 to move synchronously, and then drives the multiple groups of sliding rods 10 and the clamping plate 9 to move to the direction of the inner wall of the electric pole.
[0033] In the moving process of the clamping plate 9, the spring 12 exerts elastic pre-tightening force on the sliding rod 10 through the limiting block 11, so that the clamping plate 9 can tightly adhere to the inner wall of the electric pole, thereby ensuring that the clamping plate 9 and the inner wall of the electric pole always maintain close contact.
[0034] When the clamping plate 9 completely adheres to the inner wall of the electric pole, the operator stops rotating the rotating block 3. At this time, the meshing locking mechanism of the gear 5 and the toothed plate 6 ensures that the position of the clamping plate 9 is fixed and will not loosen due to external vibration or load action. In the clamping process, the arc-shaped design of the clamping plate 9 makes the contact surface thereof completely adhere to the inner wall of the electric pole, avoiding local stress concentration. At the same time, the combined design of the multiple groups of sliding rods 10 and the spring 12 makes the clamping force uniformly distributed, ensures that the inner wall of the electric pole is balanced in stress, and avoids structural damage caused by unilateral overload.
[0035] When the device needs to be disassembled or adjusted, the operator reversely rotates the rotating block 3, the gear 5 drives the toothed plate 6 to slide to the center, drives the sliding plate 8 and the clamping plate 9 to separate from the inner wall of the electric pole. The elastic restoring force of the spring 12 makes the sliding rod 10 and the clamping plate 9 quickly reset, facilitating the disassembly and maintenance of the device.
[0036] The above is only a specific embodiment of the utility model, but the technical features of the utility model are not limited to this. Any simple change, equivalent replacement or modification made on the basis of the utility model to solve basically the same technical problem and achieve basically the same technical effect is covered in the protection scope of the utility model.
