Description

Technical Field

[0001] This utility model relates to the field of air bag suspension bar technology, and in particular to a multi-point suspension bar for changing the position of an air bag. Background Technology

[0002] In drilling operations such as oil drilling and mining, an air bag is usually suspended under the base of the drilling rig to stabilize the system pressure. This air bag needs to move synchronously with the lateral adjustment of the drilling rig to ensure the overall operational performance of the drilling rig.

[0003] However, during the lateral movement of the air pack with the drilling rig, the limited space layout of the rig base makes it prone to positional interference with the lower base railing, leading to two key issues: First, forcibly removing the lower base railing to avoid interference would damage the original protective structure of the drilling rig, reducing the safety protection level of the work area and increasing the risk of personnel falls and equipment collisions. Second, if the railing is retained to maintain the protective function, the gap between the air pack and the railing would be significantly narrowed, severely compressing the passage space in the drilling rig's walkway area. The gap width often fails to meet industry safety passage standards, making it easy for workers to scrape against the air pack or railing when passing through this area, or even fall or bump into other safety accidents due to limited space. In summary, there is currently a lack of a tool that can meet the needs of drilling rig operations, enabling stable and precise repositioning of the air pack while ensuring safe passage for personnel. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned above in the background art by proposing a multi-point suspension bar for changing the position of an air bag.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-point suspension bar for changing the position of an air pack, comprising a mounting top plate and a suspension bar body. The surface of the mounting top plate has four mounting holes. An air pack body is fixedly mounted on the surface of the suspension bar body. An adjustment device is provided on the surface of the mounting top plate. The adjustment device includes two through slots on the surface of the mounting top plate. A sliding rod is fixedly mounted between the inner walls of the two ends of one of the through slots. A first sliding seat is slidably connected to the outer wall surface of the sliding rod. Two connecting rods are fixedly mounted on one side surface of the first sliding seat. A second sliding seat is fixedly mounted on the end of the two connecting rods away from the first sliding seat. A cylinder is fixedly mounted on the inner wall surface of one side of the other through slot. The output end of the cylinder is fixedly connected to the second sliding seat.

[0006] Preferably, a U-shaped frame is fixedly installed between the bottoms of the first sliding seat and the second sliding seat. Horizontal plates are fixedly installed on the bottom surfaces of the vertical ends on both sides of the U-shaped frame. A rotating shaft is rotatably connected between the two horizontal plates. Two motors are fixedly installed on the surface of one of the horizontal plates. The output ends of the two motors are fixedly connected to the two rotating shafts respectively through couplings.

[0007] Preferably, two connecting brackets are fixedly installed on the outer wall surfaces of both of the two rotating shafts, and the bottom of the four connecting brackets is fixedly connected to the top of the boom body.

[0008] Preferably, a PLC controller is fixedly installed on one side surface of one of the horizontal plates, and a battery box is fixedly installed on the vertical end surface of one side of the U-shaped frame. The battery box contains a battery pack. The PLC controller, cylinder, and motor are all electrically connected to the battery pack inside the battery box, and the cylinder and motor are all electrically connected to the PLC controller.

[0009] The aforementioned components achieve the following effects: by using a cylinder to move the sliding seat, connecting rod, and U-shaped frame, the lateral position of the air bag can be adjusted, easily avoiding the drill platform base railing; at the same time, by using a motor to drive the rotating shaft and connecting frame to rotate, the angle of the air bag can be flexibly adjusted, further optimizing the passage space of the drill platform aisle, avoiding safety hazards for personnel passage caused by the narrow gap between the air bag and the railing, without the need to remove the original protective railing, ensuring the integrity of the drill platform's protective structure.

[0010] Preferably, one side surface of one of the horizontal plates is provided with a limiting device, the limiting device including two U-shaped rods fixedly installed on one side surface of the other horizontal plate, two T-shaped plates slidably connected between the two U-shaped rods, insert rods fixedly installed on the surface of each of the two T-shaped plates, and multiple insertion holes matching the insert rods are circumferentially opened on the outer wall surface of each of the two rotating shafts.

[0011] Preferably, a vertical groove is formed on the surface of one vertical end of the U-shaped frame, and a T-shaped movable plate is slidably connected inside the vertical groove.

[0012] Preferably, a support plate is fixedly installed on the surface of the vertical end of one side of the U-shaped frame, an electric telescopic rod is fixedly installed on the surface of the support plate, the output end of the electric telescopic rod is fixedly connected to the T-shaped moving plate, the electric telescopic rod is electrically connected to the battery pack inside the battery box, and the PLC controller is electrically connected to the electric telescopic rod.

[0013] Preferably, the bottom surface of the T-shaped movable plate is hinged with two hinge plates, and the end of the hinge plate away from the T-shaped movable plate is hinged to the T-shaped plate.

[0014] The effect achieved by the above components is as follows: through the cooperation of the plug rod and the plug hole on the shaft, the shaft can be effectively fixed after the air bag angle is adjusted, preventing the shaft from rotating due to external force or its own weight, avoiding the air bag angle deviation, ensuring that the air bag is always in a suitable position that avoids the railing and ensures passage space, and improving the safety and stability during the operation.

[0020] Reference Figure 5-6As shown in this embodiment: a limiting device 3 is provided on one side surface of another horizontal plate 208. The limiting device 3 includes two U-shaped rods 31 fixedly installed on one side surface of the other horizontal plate 208. Two T-shaped plates 32 are slidably connected between the two U-shaped rods 31. Insert rods 33 are fixedly installed on the surface of each of the two T-shaped plates 32.

[0021] Working principle: When the device is needed, first use the four mounting holes 4 on the surface of the mounting top plate 1 to install and fix the entire device in a suitable position under the drill rig base, ensuring that the mounting top plate 1 is installed stably, providing a stable foundation for subsequent adjustment operations. When it is necessary to adjust the lateral position of the lifting bar body 5 to avoid the drill rig railing during use, first send a control signal through the PLC controller 212 to start the cylinder 206; after the cylinder 206 is started, its output end drives the second sliding seat 205 to slide along the corresponding through groove 201. Then, the second sliding seat 205 drives the two connecting rods 204 to move synchronously, and the connecting rods 204 then drive the first sliding seat 203 along the slide rod 202. The smooth sliding rod 202 on the outer wall and the first sliding seat 203 work together to ensure smooth sliding. During the synchronous movement of the first sliding seat 203 and the second sliding seat 205, the U-shaped frame 207 fixed at the bottom of the two will move laterally together. The U-shaped frame 207 will then move the horizontal plates 208 at the bottom of the vertical ends on both sides. The horizontal plates 208 will then move the rotating shaft 209 connected between them. The rotating shaft 209 will then move the lifting rod body 5 through the four connecting frames 211 fixed on the outer wall. The lifting rod body 5 will finally move the air bag body 6 fixed on the surface laterally. When the air bag body 6 moves to a suitable position that avoids the drill platform railing, the PLC controller 212 will control the movement. After closing cylinder 206, the lateral position adjustment is complete. When it is necessary to adjust the angle of the boom body 5 to expand the passage space of the drilling platform, a control signal is first sent through PLC controller 212 to start the electric telescopic rod 38 in the limit device 3. After the electric telescopic rod 38 is started, its output end drives the T-shaped moving plate 36 to slide upward along the vertical groove 35 on the vertical end of one side of the U-shaped frame 207. Then, the T-shaped moving plate 36 pulls the two T-shaped plates 32 along the surfaces of the two U-shaped rods 31 towards each other through the two hinged plates 39 at the bottom. While the T-shaped plates 32 slide, they will drive the insertion rod 33 fixed on their own surface to move synchronously. After the insertion hole 34 is completely removed, the rotating shaft 209 loses its limit. At this time, the electric telescopic rod 38 is shut off by the PLC controller 212. Then, the two motors 210 on the surface of the horizontal plate 208 are started by the PLC controller 212. The output ends of the two motors 210 drive the corresponding rotating shafts 209 to rotate synchronously through the coupling. When the rotating shaft 209 rotates, it will drive the connecting frame 211 on the outer wall to rotate together. The connecting frame 211 will then drive the lifting rod body 5 to rotate. The lifting rod body 5 will then drive the air bag body 6 to adjust the angle synchronously. When the air bag body 6 rotates to a suitable angle that meets the safety passage standard of the drilling platform passage, the motor 210 is shut off by the PLC controller 212.Next, the electric telescopic rod 38 is activated again via the PLC controller 212. The output end of the electric telescopic rod 38 drives the T-shaped moving plate 36 to slide downward along the vertical groove 35. The T-shaped moving plate 36 pushes the two T-shaped plates 32 to slide away from each other along the U-shaped rod 31 through the hinge plate 39. The T-shaped plates 32 drive the insertion rod 33 to re-insert into the corresponding insertion hole 34 of the rotating shaft 209, so that the rotating shaft 209 returns to its limit position. After the insertion rod 33 is fully inserted into the insertion hole 34 and the limit position is stable, the electric telescopic rod 38 is turned off via the PLC controller 212. Through the above-mentioned combined operation of lateral position adjustment and angle adjustment, the stable and precise position conversion of the air bag body 6 can be achieved, which not only avoids positional interference between the air bag body 6 and the drilling platform railing, but also ensures the passage space in the drilling platform aisle step area, meeting the safety requirements of the drilling platform operation scenario.
