[0017] Please see Figures 1-4The present invention provides the following technical solution: it includes a workbench body 1, a clearance hole 11 is provided at the center of the workbench body 1, a limiting ring 2 is installed on the outer wall of the workbench body 1, a connecting plate 21 is slidably connected to the limiting ring 2, a jump plate 22 is engaged and connected to the connecting plate 21, corresponding inner support block 13 and outer support block 23 are installed at the bottom of the workbench body 1 and the jump plate 22, a clearance groove 3 is provided on the workbench body 1, a drain hole 31 connected to the clearance groove 3 is provided on the workbench body 1, an adjusting ring 32 is slidably connected to the top of the workbench body 1, a push rod 33 is installed on the inner wall of the adjusting ring 32, the push rod 33 is in contact with the inner wall of the clearance groove 3, and a number of frame plates 35 are installed on the workbench body 1, and a support plate 36 is installed on the frame plates 35.

[0018] In this implementation scheme: the workbench body 1 serves as the carrier of the support device. The clearance hole 11 at the center of the workbench body 1 allows for clearance of the drilling string. The workbench body 1 is then supported on the ground outside the string, preventing mud or other debris from hindering the work platform's operation during well workover. A support plate 35 within the clearance groove 3 on the workbench body 1 supports the support plate 36, providing a work platform for the workers. The adjusting ring 32, rotatably connected to the workbench body 1, connects to the outer end of the push rod 33 via its inner wall. As the adjusting ring 32 rotates, the push rod 33 slides within the inner wall of the clearance groove 3. The support plate 36 is a perforated mesh plate, allowing mud and other debris generated during operation to directly seep into the clearance groove 3. With the rotation of the adjusting ring 32, the push rod 33 slides horizontally within the clearance groove 3, enabling it to effectively remove mud and debris from the groove. When pushed, the sludge is discharged through the drain hole 31, which is connected to the clearance groove 3 at the bottom of the work platform 1, and then discharged outside the work platform 1. This allows the device to maintain a platform that is easy for workers to operate on, avoiding the problem of too much sludge outside the well repair string making work difficult. At the same time, during use, the limiting ring 2 installed on the outer wall of the work platform 1 can install the connecting plate 21. The connecting plate 21 slides on the limiting ring 2, allowing it to slide to a position that will not restrict the construction equipment. This allows one end of the jump plate 22 to be supported on the connecting plate 21, and the jump plate 22 to be connected and supported outside the work platform 1. The inner support block 13 installed at the bottom of the work platform 1 and the outer support block 23 connected to the outer end of the jump plate 22 can support the jump plate 22 and the work platform 1 to the same horizontal height. The jump plate 22 has a certain length, allowing it to cross the construction environment, making it easy for workers to move to the work platform 1 to perform their work.

[0019] A retaining ring 12 corresponding to the clearance hole 11 is installed at the center of the workbench body 1. The retaining ring 12 installed at the center of the workbench body 1 protrudes beyond the height of the end face of the workbench body 1, so that the retaining ring 12 can prevent sludge and other substances generated during operation from entering the working position of the pipe column, so that impurities can be discharged together in the clearance groove 3.

[0020] The limiting ring 2 is connected to the workbench body 1 via a connecting block 25, and the connecting plate 21 engages with the limiting ring 2 and the connecting block 25. The limiting ring 2 and the workbench body 1 are connected via the connecting block 25, so that the limiting ring 2 can be supported and fixed outside the workbench body 1, so that it supports and limits the connecting plate 21, and the connecting plate 21 can slide steadily on the limiting ring 2 to adjust the connection position of the jump plate 22.

[0021] The connecting plate 21 and the springboard 22 are provided with corresponding locking holes 211, and the locking holes 211 are connected by locking rods 24. The locking holes 211 are used to allow one end of the springboard 22 to be supported on the connecting plate 21, so that one end of the springboard 22 can be connected to the locking holes 211 through the locking rods 24, so that the springboard 22 can be connected and supported on the connecting plate 21, thereby allowing the springboard 22 to be stably connected to the workbench body 1.

[0022] The top of the work platform body 1 is provided with an annular groove 141, and a rotating ring 14 is slidably connected to the inner wall of the annular groove 141. A guardrail 15 is installed on the rotating ring 14. The annular groove 141 on the top of the work platform body 1 can accommodate the rotating ring 14, allowing the rotating ring 14 to install the guardrail 15 to protect the workers. The rotating ring 14 slides on the inner wall of the annular groove 141, allowing the opening position of the guardrail 15 to be adjusted to correspond to the position of the springboard 22, facilitating the movement of workers.

[0023] A fixed ring 34 is rotatably connected at the center of the workbench body 1. The outer wall of the fixed ring 34 is connected to one end of the push rod 33. The fixed ring 34 rotates at the center of the workbench body 1, so that each push rod 33 can be connected through the fixed ring 34, so that it can slide stably on the inner wall of the relief groove 3, and push the push rod 33 to push the silt and other impurities on the inner wall of the relief groove 3.

[0024] The working principle and usage process of this utility model are as follows: Based on the actual well workover environment, the workbench body 1 is placed on the ground outside the drilling string, aligning the clearance hole 11 with the string position. The limiting ring 2 is fixedly installed on the outer wall of the workbench body 1 via the connecting block 25. Depending on the work area, the position of the connecting plate 21 is adjusted by sliding on the limiting ring 2, supporting one end of the ramp 22 on the connecting plate 21. The connecting plate 21 and the ramp 22 are connected and fixed using the clamping rod 24 passing through the clamping hole 211, while ensuring that the inner support block 13 and the outer support block 23 are at the same horizontal height, thus stably setting up the ramp 22 on the work environment and establishing a passage to the workbench body 1. Workers then walk to the work area via the ramp 22. On the platform body 1, well repair work is carried out while standing on the support plate 36. During the operation, silt and other impurities generated fall into the clearance groove 3 through the perforated mesh plate of the support plate 36. When it is necessary to clean the silt in the clearance groove 3, the adjusting ring 32 is rotated. The adjusting ring 32 drives the push rod 33 connected to it to rotate around the fixed ring 34. The push rod 33 slides horizontally along the inner wall of the clearance groove 3, pushing the silt towards the drain hole 31, so that the silt is discharged from the platform body 1 through the drain hole 31, thus completing the cleaning of the work platform. According to the operation requirements, the position of the rotating ring 14 is slidably adjusted in the ring groove 141 so that the opening of the guardrail 15 corresponds to the jump board 22, ensuring the safety of the workers when walking between the platform and the surrounding area.
