[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figures 1-5 As shown together, the tunnel well frame proposed in this embodiment can be built in the tunnel for use in well cleaning, and can also be used to be built above the wellhead in other narrow spaces for construction.

[0032] The tunnel's internal derrick consists of two side-by-side portal frames 1, each comprising an upper crossbeam 11 and vertical beams 12 connected at either end. The vertical beams 12 of the portal frames 1 stand upright within the tunnel, with the wellhead to be constructed located between the four vertical beams 12. The upper crossbeams 11 of the two portal frames 1 support the overhead sheave used for construction.

[0033] To ensure vertical stability, a base plate 13 is installed at the bottom of the vertical beam 12. Base plate 13 is fixed to the roadway floor. Vertical beam 12 is welded to the center of base plate 13, which contacts the ground, increasing the contact area between vertical beam 12 and the ground and making it more stable. Base plate 13 is fixed to the ground, preventing portal frame 1 from shifting or tipping over.

[0034] In order to facilitate the fixation of the bottom plate 13, the bottom plate 13 can be a square steel plate, and through holes can be provided at the four corners of the bottom plate 13. Bolts pass through the through holes to fix the bottom plate 13 to the ground.

[0035] Sometimes the vertical beam 12 is relatively high. To make the vertical beam 12 more stable and prevent it from tilting, arc-shaped hoops 2 are evenly wound around the vertical beam 12 from top to bottom. Both ends of the arc-shaped hoops 2 are fixed to the wall of the tunnel. The arc-shaped hoops 2 tighten the side of the vertical beam 12 facing the wellhead and the two side surfaces adjacent to this side surface, and then fix it to the wall surface. In this way, the arc-shaped hoops 2 firmly fix the vertical beam 12 to the wall surface and prevent the vertical beam 12 from tilting.

[0036] Sometimes the overhead sheave is used to lift heavier materials. To further support and ensure the stability of the portal frame 1, diagonal support rods 3 are connected to the sides of the vertical beams of the two portal frames 1, which are separated from each other. The diagonal support rods 3 are supported on the ground. Each vertical beam 12 is provided with a diagonal support rod 3, which is located outside the entire derrick and supports the length of the roadway. To stably support the taller portal frame 1, the upper end of the diagonal support rod 3 can be connected to the upper middle portion of the vertical beam 12. The angle between the diagonal support rod 3 and the vertical beam 12 is sufficient to provide stable support.

[0037] In order to stably install the crown block, a crown block mounting beam 4 is arranged between the two upper cross beams 11, facilitating erection of the crown block.

[0038] The size of the door-shaped frame 1 can be determined according to the size of the roadway, and can be accommodated in the roadway. The length of the upper cross beam 11 is not greater than the width of the roadway, and the included angle between the vertical beam 12 and the upper cross beam 11 can be 90-100 degrees. The length of the upper cross beam 11 and the included angle can be selected according to the specific situation. The included angle between the vertical beam 12 and the upper cross beam 11 in the embodiment is 98 degrees.

[0039] When the length of the upper cross beam 11 is the same as the width of the roadway, the included angle between the vertical beam 12 and the upper cross beam 11 is 90 degrees, and the vertical beam 12 is close to the wall of the roadway. The vertical beam 12 is fixed to the wall through the arc-shaped hoop 2. When the length of the upper cross beam 11 is less than the width of the roadway, whether the included angle between the vertical beam 12 and the upper cross beam 11 is 90 degrees or slightly greater than 90 degrees, the vertical beam 12 has a certain gap with the wall of the roadway. The vertical beam 12 can also be pulled towards the wall through the arc-shaped hoop 2, and then the arc-shaped hoop 2 is fixed to the wall to ensure that the vertical beam 12 is vertically positioned. Therefore, the well derrick in the roadway can be applied to roadways of different sizes.

[0040] In a specific embodiment of the utility model, in order to support the stable support of the inclined rod, a foot plate 5 is arranged at the bottom end of the support inclined rod 3. The foot plate 5 can be a square steel plate. Circular holes are arranged at the four corners of the foot plate 5. The foot plate 5 is fixed to the ground by passing bolts through the circular holes. The bottom end of the support inclined rod 3 is fixed to the ground. The support inclined rod 3 will not deviate from the ground during the construction process.

[0041] In a specific embodiment of the utility model, in order to stabilize the connection of the upper cross beam 11 and the vertical beam 12, a reinforcing plate 6 is arranged at the connection included angle of the upper cross beam 11 and the vertical beam 12. The reinforcing plate 6 is a steel plate connected to the middle of the connection included angle of the upper cross beam 11 and the vertical beam 12. The reinforcing plate 6 connects the upper cross beam 11 and the vertical beam 12, making the connection of the upper cross beam 11 and the vertical beam 12 more firm.

[0042] In a specific embodiment of the utility model, in order to make the connection between the vertical beams 12 more stable, a connecting beam 14 is connected between the opposite vertical beams 12 of the two door-shaped frames 1. The connecting beam 14 is connected between the middle of the opposite vertical beams, making the two door-shaped frames 1 connected into a whole, which is more stable.

[0043] The arc-shaped hoop 2 is a hoop that can pass around the vertical beam 12 and can be installed with the wall. In a specific embodiment of the utility model, the arc-shaped hoop 2 can include an arc-shaped plate 21 and connecting ears 22 connected to both ends of the arc-shaped plate 21. A middle hole is arranged on the connecting ear 22. The connecting ear 22 is fixed to the wall by a fixed rod 7 passing through the middle hole. The fixed rod 7 can include a rod cap 71 and a round rod 72 connected to each other.

[0044] A long steel plate is bent into an arc-shaped plate 21, the bending shape of the arc-shaped plate 21 is matched with the vertical beam 12, the arc-shaped plate 21 can be wound on half a circle of the outer wall of the vertical beam 12, the arc-shaped plate 21 is pulled tight through the fixing rod 7 penetrating the connecting lug 22 at both ends of the arc-shaped plate 21, holes are punched on the roadway wall, the fixing rod 7 is nailed into the holes, the fixing rod 7 is fastened in the wall, the arc-shaped plate 21 is tightly attached to the vertical beam 12, and the arc-shaped plate 21 is pulled tight towards the wall.

[0045] In one specific embodiment of the present application, the upper cross beam 11 can be an I-beam upper cross beam, the vertical beam 12 can be an I-beam vertical beam, and the support inclined rod 3 can be a steel pipe. If the derrick is under great stress, the upper cross beam 11 and the vertical beam 12 can adopt H-shaped steel.

[0046] The crown block mounting beam 4 is used for mounting the crown block for the work of the derrick, and the rope on the crown block is used for hoisting materials down the well. In one specific embodiment of the present application, the crown block mounting beam 4 can include two I-beam mounting beams 41 connected between the middle portions of the two upper cross beams 11, the two I-beam mounting beams 41 are both perpendicular to the upper cross beam 11, the end portions of the lower flanges of the two I-beam mounting beams 41 are welded to the corresponding upper cross beams 11, and the wheel shaft seats 42 are arranged at the middle portions of the upper flanges of the two I-beam mounting beams 41. The shaft of the crown block is mounted in the shaft hole of the wheel shaft seat 42.

[0047] The length of the I-beam mounting beam 41 is slightly longer than the spacing between the two upper cross beams 11, and the two I-beam mounting beams 41 are arranged on the middle portions of the two upper cross beams 11. The two ends of the wheel shaft of the crown block are arranged in the bearings of the wheel shaft seats 42, the wheel shaft seats 42 are arranged at the upper central portions of the I-beam mounting beams 41, and the crown block rotates smoothly in the wheel shaft seats 42.
