DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, a wellhead support and protection device provided by the utility model comprises a protection net 1, a fixing device 2 and a support block 3, the back side of the fixing device 2 is fixedly connected to the front side of the protection net 1, the inner side of the support block 3 is fixedly connected to the two sides of the fixing device 2, a slide groove 4 is provided on the inner side of the front side of the support block 3, a slide cylinder 5 is slidably connected to the inner wall of the slide groove 4, an adjusting screw 6 is connected to the internal thread of the slide cylinder 5, a rotating disk 7 is fixedly connected to the front side of the adjusting screw 6, an extension rod 8 is fixedly connected to the back side of the slide cylinder 5, and the back side of the extension rod 8 is movably connected through an axle pin There is a clamping plate 9, the top and bottom of the extension rod 8 are fixedly connected with a first docking block 10, a second docking block 11 is arranged on the back of the first docking block 10, the outer side of the second docking block 11 is fixedly connected with the two sides of the clamping plate 9 through an axle pin, a fastening bolt 12 is arranged on the front of the first docking block 10, the front side of the fastening bolt 12 penetrates through the back of the first docking block 10 and is connected with the internal thread of the second docking block 11, an auxiliary adjustment component 13 is provided on the front side of the surface of the adjusting screw 6, and support components 14 are provided on both sides of the inner side of the front side of the support block 3.

[0024] refer to Figure 3 and Figure 4 The auxiliary adjustment component 13 includes an annular groove 131, which is opened on the front side of the surface of the adjusting screw 6. The inner wall of the annular groove 131 is slidably connected to a limiting member 132. The back of the limiting member 132 is fixedly connected to the front of the support block 3. Three limiting members 132 are arranged and are distributed equidistantly in a ring shape.

[0025] As a technical optimization scheme of the utility model, by setting an auxiliary adjustment component 13, when the operator rotates the rotating disk 7 to rotate the adjusting screw 6, the annular groove 131 moves in contact with the surface of the limit piece 132, and the adjusting screw 6 is limited and supported when it pushes the slide 5 in the reverse direction or resets the slide 5 in the forward direction, so that the adjusting screw 6 can rotate in situ, preventing the operator from needing to rotate the adjusting screw 6 while pushing or pulling the adjusting screw 6 to make the slide 5 move or reset when the operator controls the adjusting screw 6 in the forward or reverse direction to move or reset the slide 5, thereby increasing the work intensity and improving the convenience of the operator's operation.

[0026] refer to Figure 4 The support assembly 14 includes a support groove 141, which is opened on both sides of the inner side of the front side of the support block 3. The inner wall of the support groove 141 is slidably connected with a support rod 142, and the back side of the support rod 142 is fixedly connected to the two sides of the front side of the extension rod 8.

[0027] As a technical optimization scheme of the utility model, by setting the support assembly 14, when the slide 5 moves along the track of the slide groove 4, the support rod 142 moves along the track of the support groove 141, and provides auxiliary support to the extension rod 8, sharing the pressure of the extension rod 8 and the clamping plate 9 on the slide 5, and preventing the slide 5 from moving outward along the track of the slide groove 4. The connection between the slide 5 and the slide groove 4 becomes less and less, and the extension rod 8 and the clamping plate 9 exert a heavier self-hanging pressure on the slide 5, causing the slide 5 to tilt slightly, making it difficult for the adjusting screw 6 to rotate, thereby improving the support stability of the slide 5 on the extension rod 8 and the clamping plate 9 when the connection between the slide 5 and the slide groove 4 becomes less and less.

[0028] refer to Figure 4 The top and bottom of the inner wall of the support groove 141 are both provided with a limiting groove 15 , and the inner wall of the limiting groove 15 is slidably connected to the limiting block 16 .

[0029] As a technical optimization scheme of the utility model, by setting the limit groove 15 and the limit block 16, when the slide 5 moves along the track of the slide groove 4, the support rod 142 simultaneously moves along the track of the support groove 141 to push the extension rod 8 and the clamping plate 9, the limit block 16 moves along the track of the limit groove 15 to limit the maximum movement distance of the support rod 142. At the same time, the maximum movement distance of the slide 5 along the track of the slide groove 4 is limited, preventing the operator from rotating the adjusting screw 6 too far due to improper observation and operating errors when rotating the adjusting screw 6 through the rotating disk 7, causing the slide 5 to disengage from the adjusting screw 6, resulting in the extension rod 8 and the clamping plate 9 being disconnected from the support block 3 and causing losses, thereby improving the stability of the operator turning the adjusting screw 6 to control the extension rod 8 and the clamping plate 9.

[0030] refer to Figure 3Balls 17 are embedded on both sides and the bottom of the inner wall of the annular groove 131. The inner side and the top of the ball 17 are slidably connected to the surface of the limiter 132. A plurality of balls 17 are arranged and distributed in an annular shape with equal distances.

[0031] As a technical optimization scheme of the utility model, by arranging the ball 17, when the adjusting screw 6 rotates and is supported by the ring groove 131 and the limit piece 132 so as to be able to rotate in place, the ball 17 rolls and at the same time isolates the contact between the limit frame and the ring groove 131, thereby reducing the friction resistance, thereby allowing the operator to rotate the adjusting screw 6 more smoothly and easily through the rotating disk 7, and preventing the operator from rotating the adjusting screw 6 with great effort due to the direct contact between the ring groove 131 and the limit piece 132, thereby allowing the operator to rotate the adjusting screw 6 more easily through the rotating disk 7, thereby improving the operator's work efficiency.

[0032] refer to Figure 2 A magnetic block 18 is fixedly connected to the bottom of the inner side of the clamping plate 9 , and the bottom of the magnetic block 18 is magnetically adsorbed to the inner side of the second docking block 11 .

[0033] As a technical optimization scheme of the utility model, by setting a magnetic block 18, after the clamping plate 9 is rotated to fit the wall, when the first docking block 10 needs to be connected to the second docking block 11 by the fastening bolt 12, the user rotates the second docking block 11 at the top and bottom of the clamping plate 9 to be flush and overlapped with the first docking block 10, and at the same time, the second docking block 11 at the bottom of the clamping plate 9 is magnetically adsorbed and fixed by the magnetic block 18, preventing the operator from passing the fastening bolt 12 through the first docking block 10 and connecting it with the second docking block 11 at the bottom of the clamping plate 9. It is inconvenient for the operator to hold the second docking block 11 while rotating the fastening bolt 12 to connect the first docking block 10 with the second docking block 11 through the fastening bolt 12 to achieve the limited fixation of the clamping plate 9, thereby improving the convenience of operation for the operator.

[0034] refer to Figure 2 A first rubber gasket 19 is fixedly connected to the outer side of the back side of the support block 3 , and a second rubber gasket 20 is fixedly connected to the front side of the clamping plate 9 .

[0035] As a technical optimization scheme of the utility model, by setting the first rubber gasket 19 and the second rubber gasket 20, when the support block 3 and the clamping plate 9 cooperate to clamp and limit the wall to fix the protective net 1, the first rubber gasket 19 and the second rubber gasket 20 are deformed by the extrusion when the clamping block and the support block 3 are fitted, and the rebound force generated by the first rubber gasket 19 and the second rubber gasket 20 at the same time can absorb part of the stress, reduce the damage of the support block 3 and the clamping block to the structure of the surface layer of the concrete wall, prevent the surface of the concrete wall from being damaged and powdered, and cause gaps to appear, which makes the protective net 1 loose after installation, thereby improving the long-term stability of the protective net 1 after installation.

[0036] The working principle and use process of the utility model are as follows: when in use, the operator places the protective net 1 on the elevator shaft opening, and adjusts the fixing device 2 to make the support block 3 fit tightly against the door frame of the elevator shaft opening, so that the protective net 1 is limited and fixed, and then the rotating disk 7 is rotated, and the adjusting screw 6 rotates, and at the same time, the annular groove 131 fits the surface of the limiting piece 132 and moves, and the adjusting screw 6 is limited and supported when the sliding cylinder 5 is reversed or the sliding cylinder 5 is reset in the forward rotation, so that the adjusting screw 6 rotates in place, so that the sliding cylinder 5 moves along the track of the sliding groove 4, and the support rod 142 moves along the track of the support groove 141. The limit block 16 moves along the trajectory of the limit groove 15 to push the extension rod 8 and the clamping plate 9. When the extension rod 8 and the clamping plate 9 are pushed to the point where the clamping plate 9 can be rotated and fit the wall, the operator rotates the clamping plate 9 to fit the wall, and then rotates the second docking block 10 to overlap flush with the first docking block 10, and then passes the fastening bolt 12 through the first docking block 10 and is threadedly connected to the second docking block 11, so that the second docking block 11 is fixed by the first docking block 10, thereby achieving the limited fixation of the clamping plate 9, so that the clamping plate 9 cooperates with the support block 3 to clamp the wall, thereby having the advantage of auxiliary installation.

[0037] To sum up: the wellhead support protection device, by setting the clamping plate 9 and the slide 5, when the protective net 1 is installed on the elevator wellhead, the rotating disk 7 is rotated to rotate the adjusting screw 6, so that the slide 5 moves, and the extension rod 8 and the clamping plate 9 are moved together until the clamping plate 9 can be rotated and fit the wall, and then the fastening bolt 12 is rotated to fix the second docking block 11 by the first docking block 10, so as to achieve the limited fixation of the clamping plate 9, which solves the problem that the structure of the surface layer of the concrete wall is relatively loose, especially at the corners, the support block is closely fitted with the wall for a long time, which will cause wear, the surface of the wall will appear powdery, and the support block is difficult to fit tightly with the wall in the long term, causing the protective net to tilt and collapse.
