DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1 - Figure 5 As described, the present embodiment proposes a high-performance HDPE wellbore pipe fixing tool, including a fixing barrel 1, at the lower end of which are installed two groups of symmetrically arranged second fixing plates 14, on which are opened through holes, and a plurality of groups of through holes. In the present embodiment, the second fixing plate 14 is provided with two groups of symmetrically arranged through holes. When working, the second fixing plate 14 mainly serves to connect with the external platform equipment, so that the fixing barrel 1 can be linked with the external platform equipment. When the device needs to be transported, the fixing barrel 1 can be inverted, and at this time, the second fixing plate 14 is located above the fixing barrel 1. The corresponding through hole arrangement facilitates the connection structure of the external lifting equipment to be connected with the second fixing plate 14, so it is convenient to lift the fixing barrel 1 and then transfer it.

[0023] A driving cylinder 2 is provided on the inner side of the fixed cylinder 1, and clamping components are installed in the driving cylinder 2 and the fixed cylinder 1. The driving cylinder 2 can move on the inner side of the fixed cylinder 1. In the present embodiment, the fixed cylinder 1 is in a fixed state, and the driving cylinder 2 is in an active state. After the high-performance HDPE wellbore pipe is clamped, the driving cylinder 2 is moved to drive the high-performance HDPE wellbore pipe to move, thereby achieving a feeding effect. Therefore, the present device can not only clamp and fix the high-performance HDPE wellbore pipe, but also can feed the pipe according to the processing requirements, and has good practicality. At the same time, the fixed cylinder 1 and the driving cylinder 2 wrap the high-performance HDPE wellbore pipe inside, which can provide a certain protection effect when fixing the high-performance HDPE wellbore pipe.

[0024] The clamping assembly includes two sets of symmetrically arranged clamping plates 8, such as Figure 5 As shown, the clamping plate 8 is arranged in an arc shape, and a protective rubber layer 13 is installed on the inner side of the clamping plate 8, and the curvature of the clamping plate 8 fits the curvature of the wellbore pipe, so that the clamping plates 8 on both sides are connected to the high-performance HDPE wellbore pipe through the protective rubber layer 13, and have a certain protective effect while playing a clamping role, that is, the protective rubber layer 13 plays a buffering protection role to prevent the clamping plate 8 from affecting the surface of the high-performance HDPE wellbore pipe. One side of the corresponding clamping plate 8 is equipped with an electric push rod 9 on the fixed cylinder 1 and the driving cylinder 2 at the corresponding position, and the telescopic end of the electric push rod 9 is connected to the clamping plate 8, and then under the action of the electric push rods 9 on both sides, the clamping plate 8 is driven to move toward the high-performance HDPE wellbore pipe, and then a clamping force is generated on it.

[0025] During operation, clamping plates 8 are installed in both the fixed cylinder 1 and the driving cylinder 2. During the processing of high-performance HDPE wellbore pipes, all the clamping plates 8 are clamped. When feeding is required, the clamping plates 8 in the fixed cylinder 1 are loosened (this loosening does not mean complete loosening, but allows the clamping plates 8 to move inside the clamping plates 8). By adjusting the position of the driving cylinder 2, the clamping plates 8 are driven to move, thereby forming a feeding effect. After reaching the predetermined position, the clamping plates 8 in the fixed cylinder 1 can be clamped.

[0026] The upper and lower sides of the driving cylinder 2 are both provided with first openings 3 on the fixed cylinder 1, and the upper and lower sides of the driving cylinder 2 are both provided with extensions 4, and the extensions 4 pass through the first openings 3, the lower end of the lower extension 4 is located in the lower first opening 3, and the first fixing plates 5 are installed on the fixed cylinder 1 on both sides of the upper extension 4, as shown in FIG. Figure 1 and Figure 3As shown, a screw rod 6 is installed between the first fixed plates 5 on both sides through bearings, and the screw rod 6 is driven by a motor 7. The motor 7 is located on the right side of the first fixed plate 5 on the right side, and is connected to the fixed cylinder 1 through a bracket. At the same time, the screw rod 6 passes through the extension part 4 and is connected to the extension part 4 through a thread. Therefore, when working, the motor 7 drives the screw rod 6 to rotate, and then under the action of the threaded connection, the extension part 4 is driven to move, thereby driving the driving cylinder 2 to move. Correspondingly, two groups of symmetrically arranged sliding rods 15 are installed in the first opening 3. The sliding rod 15 is connected to the fixed cylinder 1, and the sliding rod 15 passes through the extension part 4 to ensure the stability of the extension part 4 when it moves.

[0027] The fixing cylinder 1 is provided with a second opening 10 on both sides, namely, the front and rear sides. The length of the second opening 10 is greater than the first opening 3. The corresponding second opening 10 is connected to the outside at one end close to the driving cylinder 2. In this embodiment, the main purpose of the second opening 10 is to facilitate the entry of the electric push rod 9. Secondly, a positioning portion 11 is provided on the inner side of the second opening 10, and the positioning portion 11 is connected to the driving cylinder 2. At the same time, the positioning portion 11 passes through the second opening 10, and the cross-section of the positioning portion 11 is convex, that is, the length of the end of the positioning portion 11 away from the second opening 10 is greater than the width of the second opening 10. Figure 4 As shown, a scale indicator line 12 is provided on one side of the corresponding positioning portion 11 on the fixed cylinder 1. Then, when the position of the driving cylinder 2 changes, the position of the positioning portion 11 also changes successively, and the scale of the scale indicator line 12 corresponding to the positioning portion 11 also changes. Therefore, the moving position of the driving cylinder 2 can be determined by the corresponding scale change, which provides convenience for the subsequent high-performance HDPE wellbore pipe processing.
