[0022] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown: it includes a base plate 100 and a clamping mechanism 200 provided on the base plate 100. The clamping mechanism 200 includes two slides symmetrically provided above the base plate 100. The clamping mechanism 200 can drive the two slides to move relative to each other or move away from each other.

[0024] In this embodiment, multiple support bases 101 are arranged in a linear array. Each support base 101 is provided with a rotating rod 102 via a bearing. The rotating rod 102 can rotate on the support base 101. The multiple rotating rods 102 are transmission-connected to each other, and the multiple rotating rods 102 can rotate synchronously through the transmission. A roller 103 is provided at the end of each rotating rod 102. The rotation of the rotating rod 102 can drive the roller 103 to rotate. The roller 103 has a conical structure, and the wider side of the roller 103 is connected to the end of the rotating rod 102.

[0025] That is, when casing a steel pipe, the steel pipe is placed between two rows of rollers 103. The two rows of tapered rollers 103 can support the steel pipe and control the rotation of multiple rotating rods 102. The multiple rotating rods 102 can rotate synchronously through transmission, and the multiple rotating rods 102 can drive the multiple rollers 103 to rotate. The rotation of the rollers 103 can drive the steel pipe to move horizontally under the action of friction.

[0026] When the production model of the insulation pipe is changed, the clamping mechanism 200 can be controlled to work, and the clamping mechanism 200 can indirectly drive the two slides to move relative to each other or move away from each other, and then drive the two rows of conical rollers 103 to move relative to each other or move away from each other. When the two rows of rollers 103 move relative to each other, the height of the steel pipe can be increased, and when the two rows of rollers 103 move away from each other, the height of the steel pipe can be lowered, so that the steel pipe can always be inserted into the casing.

[0027] like Figure 1 、 2 ,4,

[0028] The clamping mechanism 200 includes two support plates 201 symmetrically arranged on the base plate 100, and a bidirectional threaded rod 202 is provided between the two support plates 201 through a bearing. The threads on both sides of the bidirectional threaded rod 202 are opposite, and the two sides of the threaded rod 202 are connected to the support plates 201 through bearings. The threaded rod 202 can rotate between the two support plates 201, and the corresponding threaded rod 202 is also provided with a threaded hole 203 on the slide. The threaded rod 202 passes through the threaded hole 203 and is connected to the slide. The two slides are located on both sides of the threaded rod 202, and the threads are connected to the slide. The rotation of the rod 202 can make the two slides move relative to each other or move away from each other. The bottom plate 100 is further provided with a first motor 204 corresponding to the threaded rod 202. The output shaft of the first motor 204 is connected to the end of the threaded rod 202. When the first motor 204 is working, it can drive the threaded rod 202 to rotate, and then it can indirectly drive the two slides to move relative to each other or move away from each other, so that the two rows of rollers 103 can move relative to each other or move away from each other. The relative movement or movement of the two rows of rollers 103 can achieve the purpose of adjusting the height of the steel pipe.

[0029] A plurality of guide rods 205 are further provided between the two support plates 201. In this embodiment, there are two guide rods 205, which are arranged parallel to the threaded rod 202. Two guide holes 206 are provided on the slide corresponding to the guide rods 205. The guide rods 205 are connected to the support plates 201 through the guide holes 206. That is, the guide rods 205 can provide guidance for the slide when the slide moves, thereby preventing the slide from shaking or rotating with the threaded rod 202 when the threaded rod 202 rotates.

[0030] like Figure 1 、 3 As shown,

[0031] The first pulley 300 is provided at one end of each rotating rod 102 away from the roller 103, and each first pulley 300 is coaxially arranged with the rotating rod 102, and every two adjacent first pulleys 300 are connected by a belt, so that the rotating rods 102 adjacent to each other can rotate synchronously, and further, multiple rotating rods 102 can rotate synchronously, and the two skateboards are further provided with a second motor 301, and a second pulley 302 is on the output shaft of the second motor 301. The second pulley 302 is connected to the closest first pulley 300 by a belt, and the second motor 301 can drive the second pulley 302 to rotate;

[0032] That is, when the steel pipe needs to be transported, the second motors 301 on the two slides are controlled to work, and the output shaft speeds of the two second motors 301 should be kept consistent. The second motor 301 can drive the second pulley 302 to rotate, and the rotation of the second pulley 302 can drive the closest first pulley 300 to rotate through the belt, thereby indirectly making multiple first pulleys 300 rotate synchronously, and then indirectly making the two rows of rollers 103 rotate synchronously, so that the two rows of rollers 103 can drive the steel pipe to move laterally through friction.

[0033] like Figure 3 、 4 As shown,

[0034] A reinforcing block 104 is also provided on the side of the support seat 101 away from the roller 103. The reinforcing block 104 is connected to the rotating rod 102 through a bearing. The reinforcing block 104 can strengthen the structural strength of the rotating rod 102, thereby preventing the rotating rod 102 from being deformed by the gravity of the steel pipe during the transportation of the steel pipe.

[0035] like Figure 4 As shown,

[0036] The end of the rotating rod 102 away from the pulley is provided with a thread, and the corresponding thread of the roller 103 is threadedly connected to the end of the rotating rod 102, that is, the roller 103 can be removed from the rotating rod 102, so that it is easy to remove the roller 103, and the removal of the roller 103 can facilitate the replacement or maintenance of the roller 103.

[0037] A rubber pad is provided on the outer wall of each roller 103 , which can increase the friction between the roller 103 and the steel pipe, thereby preventing the roller 103 from scratching the outer wall of the steel pipe and preventing the steel pipe from slipping between the two rows of rollers 103 .

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
