Description

Technical Field

[0002] The telescopic slide of a water well drilling rig is a mechanical device used to support and move the drill pipe. The key lies in its telescopic function to adapt to the drilling needs of different depths.

[0003] For example, the "A multi-cylinder telescopic slide for a water well drilling rig" with the publication number CN211115806U includes an outer slide, an inner slide, a pulley, a slide plate and a chain, an inner slide is arranged inside the outer slide, a rear guide sprocket frame is arranged at the upper end of the inner slide, an upper sprocket is arranged in the rear guide sprocket frame, a pulley is arranged on the inner side of the inner slide, a pulley sprocket is arranged in the pulley, a lower sprocket is arranged at the lower end of the inner slide, an upper chain is arranged above the inner slide and a lower chain is arranged below the inner slide; by cooperating with multiple sets of upper sprockets, lower sprockets and pulley sprockets and utilizing the principle of double speed, the stroke of the pulley is made twice the stroke of the cylinder, so the stroke required by the cylinder is shortened, the length of the slide is greatly shortened, the manufacturing cost is reduced, and the drilling rig structure is made more reliable and convenient to transport. At the same time, since the inner slide is directly connected to the outer slide through the external oil cylinder, the lifting force and propulsion force of the inner slide can be effectively improved, the construction capacity is greatly enhanced, the self-rescue ability during buried drilling is stronger, and the construction efficiency is higher.

[0004] However, in the prior art, although this type of telescopic slide has improved the lifting force and propulsion force of the inner slide, greatly enhanced the construction capacity, stronger self-rescue ability during buried drilling, and higher construction efficiency, it is lacking in the folding and transportation of the telescopic slide. Since this type of telescopic slide can only telescope and slide the motor but cannot telescope and adjust the bracket, and drilling equipment often needs to be transported during drilling, and the telescopic slide used for drilling does not have the function of telescopic adjustment, which will result in the need to use a larger transportation tool to transport the slide, which not only requires a lot of manpower to carry or install it, but also greatly increases the transportation cost of the telescopic slide.

[0017] 2. In the present invention, by shifting the shift block, the shift block slides inside the limit groove C, thereby driving the insertion block B to move. After the insertion block B slides away from the surface of the extension plate, the extension plate will rotate due to the torsion force of the torsion spring A. After the extension plate is rotated out of the receiving groove A, the base will be rotated. When the base rotates, it will drive the bottom plate to rotate.

After the extension plate touches the insertion block B, it will drive the insertion block B to slide inside the bottom plate. After the extension plate is attached to the receiving groove A, the insertion block B will slide inside the bottom plate due to the elastic force of the spring until the insertion block B clamps the extension plate, thereby completing the storage of the extension plate. The design of the extension plate increases the contact area between the bottom plate and the ground when the base is rotated, thereby preventing the base from tipping over. At the same time, it also facilitates the fixation of the bottom plate and the storage of the extension plate.

[0018] When the lever is in the position of being moved away from the support frame, the lever B is moved out of the locking chute and the lever B is moved in a direction in which the lever is moved in.

[0023] In this embodiment, the extension frame A106 is driven upward by the electric push rod 105, and the extension frame A106 drives the limit block A109 to slide inside the limit groove A107. At this time, the limit block A109 drives the limit wheel A108 to rotate. When the extension frame A106 moves upward, it drives the toothed chain 120 to roll on the surface of the gear A118 and the gear B119 through the clamping plate A122, thereby driving the gear A118 and the gear B119 to rotate. At this time, the toothed chain 120 drives the gear A118 and the gear B119 to rotate. The clamping plate B123 moves upward, thereby driving the extension frame B114 to move upward, and the extension frame B114 drives the limit block B113 to slide inside the limit groove B111, thereby driving the limit wheel B112 to rotate. At this time, the extension frame B114 drives the motor 116 to move upward, thereby completing the deployment of the telescopic slide, and also plays the effect of sliding the motor 116 up and down, thereby avoiding the situation where the slide cannot be extended and needs to be transported and assembled with the help of large-scale transportation equipment; By rotating the lever 125, the lever 125 can be slid after it rotates to contact the ground, and the lever 125 can be rotated again after it moves from the other side of the bidirectional screw rod 124. When the lever 125 rotates, it will drive the bidirectional screw rod 124 to rotate. When the bidirectional screw rod 124 rotates, it will drive the connecting block A126 and the connecting block B127 to slide in opposite directions inside the bottom plate 104, thereby driving the baffle A128 and the baffle B129 to slide to both sides of the bottom plate 104, thereby expanding the size of the aperture of the limit hole 130, so as to facilitate the replacement and adjustment of the drilling rod by the staff; By rotating the insertion rod A117, the insertion rod A117 can be pulled out from the extension frame B114 after the insertion rod A117 is rotated out of the extension frame B114. At this time, the motor 116 is pulled outward, and the motor 116 will drive the insertion block A115 to be pulled out from the extension frame B114, thereby completing the disassembly of the motor 116, thereby facilitating the maintenance and replacement of the motor 116 by maintenance personnel, and also facilitating the disassembly and transportation of the motor 116.

[0024] Embodiment 2: Figure 6-7As shown, a receiving groove A200 is provided on the surface of the bottom plate 104, a limiting groove C201 is provided on the surface of the bottom plate 104, a rotating rod A202 is rotatably connected inside the bottom plate 104, a torsion spring A203 is sleeved on the surface of the rotating rod A202, an extension plate 204 is fixedly installed on one end of the rotating rod A202, a sliding rod 205 is slidably connected inside the bottom plate 104, a spring 206 is sleeved on the surface of the sliding rod 205, an insert block B207 is fixedly installed on one end of the sliding rod 205, and a torsion spring A203 is sleeved on the surface of the rotating rod A202. An extension plate 204 is fixedly installed on one end of the rotating rod A202. A shift block 208 is installed, and a foundation pile hole A209 is opened through the surface of the extension plate 204. One end of the torsion spring A203 is connected to the side of the extension plate 204, and the other end is connected to the inner surface of the bottom plate 104. One end of the spring 206 is connected to the surface of the plug block B207, and the other end is connected to the inner surface of the bottom plate 104. The plug block B207 is slidably connected to the bottom plate 104, and the shift block 208 is slidably connected to the limit groove C201. The shape of the side where the plug block B207 contacts the extension plate 204 is an arc.

[0025] In this embodiment, by moving the shift block 208, the shift block 208 slides inside the limit groove C201, thereby driving the plug block B207 to move. After the plug block B207 slides off the surface of the extension plate 204, the extension plate 204 will rotate due to the torsion of the torsion spring A203. After the extension plate 204 is rotated out of the storage groove A200, the base 100 will be rotated. When the base 100 rotates, it will drive the bottom plate 104 to rotate. After the bottom plate 104 is attached to the ground, the foundation pile can be driven into the foundation pile hole A209, thereby completing the fixation of the bottom plate 104. When it is necessary to store the extension plate 204, it only needs to rotate the extension plate 204. After the extension plate 204 touches the plug block B207, it will drive the plug block B207 to slide towards the inside of the bottom plate 104. After the extension plate 204 is fitted into the storage groove A200, the plug block B207 will be affected by the elastic force of the spring 206 and slide inside the bottom plate 104 until the plug block B207 clamps the extension plate 204, thereby completing the storage of the extension plate 204. The design of the extension plate 204 increases the contact area between the bottom plate 104 and the ground when the base 100 is rotated, thereby preventing the base 100 from tipping over. At the same time, it also facilitates the fixing of the bottom plate 104 and the storage of the extension plate 204.

[0026] Embodiment 3: According to Figure 8-9As shown, a storage groove B300 is provided on the surface of the base 100, an extension rod 301 is rotatably connected inside the base 100, a connecting rod 302 is slidably connected inside the extension rod 301, a positioning hole 303 is penetrated on the surface of the connecting rod 302, a rotating plate 304 is rotatably connected to one end of the connecting rod 302, a foundation pile hole B305 is penetrated on the surface of the rotating plate 304, an insertion rod B306 is inserted inside the extension rod 301, a protrusion 307 is fixedly installed on the surface of the base 100, and a rotating rod B308 is rotatably connected inside the base 100. A torsion spring B309 is sleeved on the surface of the rotating rod B308, and a clamping block 310 is fixedly installed on the surface of the rotating rod B308. The insertion rod B306 is slidably connected to the connecting rod 302, the insertion rod B306 is threadedly connected to the extension rod 301, the extension rod 301 and the rotating plate 304 are slidably connected to the storage slot B300, one end of the torsion spring B309 is connected to the surface of the clamping block 310, and the other end is connected to the inner surface of the base 100, the clamping block 310 is slidably connected to the base 100, and the clamping block 310 is slidably connected to the rotating plate 304.

[0027] In this embodiment, by rotating the block 310, the extension rod 301 can be rotated out of the storage groove B300 after the block 310 is away from the rotating plate 304. At this time, the connecting rod 302 is pulled outward, and the connecting rod 302 will drive the rotating plate 304 to move outward. After the rotating plate 304 is in contact with the ground, the insertion rod B306 can be inserted into the extension rod 301. At this time, the insertion rod B306 will slide in a certain positioning hole 303, and then the insertion rod B306 will be connected to the extension rod 301 through a thread. After the insertion rod B306 is connected, the foundation pile can be inserted into the foundation pile hole B305, thereby completing the fixation of the base 100. When the extension rod 301 needs to be stored, the connecting rod 302 only needs to be stored in the extension rod 301 first, and then the extension rod 301 is rotated into the storage groove B300, and then the block 310 is released. The block 310 will be rotated by the torsion force of the torsion spring B309 until the block 310 fits on the surface of the protrusion 307, thereby completing the storage of the extension rod 301. The design of the extension rod 301 not only fixes the base 100 and prevents the base 100 from tipping over, but also facilitates the storage of the extension rod 301, saving space and facilitating the assembly of the slide.

[0028] The use method and working principle of the device: when the drilling rod needs to be installed, the electric push rod 105 only needs to be opened, and the electric push rod 105 will drive the extension frame A106 to move upward, and the extension frame A106 will drive the limit block A109 to slide inside the limit groove A107, at this time, the limit block A109 will drive the limit wheel A108 to rotate, and when the extension frame A106 moves upward, it will drive the tooth chain 120 to roll on the surface of the gear A118 and the gear B119 through the clamping plate A122, thereby driving the gear A118 and the gear B119 to rotate, and at this time the tooth chain 120 When the extension frame B114 rotates, it will drive the clamping plate B123 to move upward, thereby driving the extension frame B114 to move upward, and the extension frame B114 will drive the limit block B113 to slide inside the limit groove B111, thereby driving the limit wheel B112 to rotate. At this time, the extension frame B114 will drive the motor 116 to move upward, thereby completing the deployment of the telescopic slide. After the telescopic slide is deployed, the drilling rod can be installed, and at the same time, the motor 116 can slide up and down, thereby avoiding the need to use large-scale transportation equipment to transport and assemble the slide due to the non-retractable slide. When the telescopic slide is stored, the traction block 103 and the roller 101 can be used to transport the telescopic slide. When the base 100 needs to be turned over, the telescopic slide can be turned over by the roller 101 and the handle 102. When the size of the limit hole 130 needs to be adjusted, the lever 125 only needs to be rotated. After the lever 125 is rotated to contact the ground, the lever 125 can be slid. After the lever 125 is moved from the other side of the bidirectional screw rod 124, the lever 125 can be rotated again. When the lever 125 is rotated, the bidirectional screw rod 124 will be driven to rotate. When the bidirectional screw rod 124 is rotated, the connecting block A126 and the connecting block B127 will slide in opposite directions inside the bottom plate 104, thereby driving the baffle A128 and the baffle B129 to slide to the two sides of the bottom plate 104, thereby expanding the size of the aperture of the limit hole 130, so as to facilitate the replacement and adjustment of the drilling rod by the staff; When the motor 116 needs to be disassembled, it is only necessary to rotate the plug A117. After the plug A117 is rotated out of the extension frame B114, the plug A117 can be pulled out of the extension frame B114. At this time, the motor 116 is pulled outward, and the motor 116 will drive the plug A115 to be pulled out of the extension frame B114, thereby completing the disassembly of the motor 116, thereby facilitating the maintenance and replacement of the motor 116 by maintenance personnel, and also facilitating the disassembly and transportation of the motor 116. When the base 100 needs to be flipped, the shifting block 208 only needs to be shifted to make the shifting block 208 slide inside the limiting groove C201, thereby driving the plug block B207 to move. After the plug block B207 slides off the surface of the extension plate 204, the extension plate 204 will rotate due to the torsion of the torsion spring A203. After the extension plate 204 is rotated out of the storage groove A200, the base 100 will be rotated. When the base 100 rotates, it will drive the bottom plate 104 to rotate. After the bottom plate 104 is attached to the ground, the foundation pile can be driven into the foundation pile hole A209, thereby completing the fixation of the bottom plate 104. When the extension plate 204 needs to be stored, the extension plate 20 4 rotates, and when the extension plate 204 touches the plug block B207, the plug block B207 will slide toward the inside of the bottom plate 104. When the extension plate 204 fits into the storage groove A200, the plug block B207 will slide inside the bottom plate 104 under the elastic force of the spring 206 until the plug block B207 clamps the extension plate 204, thereby completing the storage of the extension plate 204. The design of the extension plate 204 increases the contact area between the bottom plate 104 and the ground when the base 100 is rotated, thereby preventing the base 100 from tipping over. At the same time, it also facilitates the fixing of the bottom plate 104 and the storage of the extension plate 204. When it is necessary to fix the rotating plate 304 and the base 100, it is only necessary to rotate the block 310. After the block 310 is away from the rotating plate 304, the extension rod 301 can be rotated out of the storage slot B300. At this time, the connecting rod 302 is pulled outward, and the connecting rod 302 will drive the rotating plate 304 to move outward. After the rotating plate 304 is attached to the ground, the insertion rod B306 can be inserted into the extension rod 301. At this time, the insertion rod B306 will slide in a certain positioning hole 303, and then the insertion rod B306 is connected to the extension rod 301 through a thread. After the insertion rod B306 is connected, the foundation pile can be inserted into the foundation pile hole B305, thereby completing the base. 100 is fixed. When the extension rod 301 needs to be stored, it is only necessary to first store the connecting rod 302 into the extension rod 301, and then rotate the extension rod 301 to the storage groove B300. At this time, the block 310 is released, and the block 310 will rotate under the torsion force of the torsion spring B309 until the block 310 fits on the surface of the protrusion 307, thereby completing the storage of the extension rod 301. The design of the extension rod 301 not only fixes the base 100 and prevents the base 100 from tipping over, but also facilitates the storage of the extension rod 301, saves space and is also convenient for assembling the slide.
