Description

Technical Field

[0001] This utility model relates to the technical field of slag discharge devices, and in particular to a guiding device applied to the slag discharge device of a double rotary drilling rig. Background Technology

[0002] Double rotary drilling rigs are widely used in drilling operations, especially in soft soil, sandy layers or complex geological conditions. To ensure the quality of subsequent construction, it is necessary to clean up the mud, soil and other waste materials in the borehole after drilling is completed, so as to avoid the waste materials from adhering and accumulating at the bottom or wall of the hole.

[0003] Traditional slag removal devices typically use a winch to control a single collection bucket to collect waste material from the borehole. However, the capacity of a single collection bucket is limited, requiring repeated operations, resulting in low slag removal efficiency. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a guiding device for a slag discharger of a double rotary drilling rig, comprising a top section, a slag discharge cylinder, a slag discharge cable, a winch, and a lifting cable. A slag discharge cylinder is provided on one side of the top section, and a set of one or more slag discharge cylinders are connected to the bottom of the top section through the slag discharge cable. A positioning ring for connecting the slag discharge cable is provided at the top of the slag discharge cylinder, and the positioning rings are combined to form a virtual cylinder. A winch for winding and unwinding the lifting cable is provided in the top section, and the output end of the winch is connected to the bottommost slag discharge cylinder through the lifting cable.

[0005] Using the above technical solution, after the drilling rig completes drilling, the top section is moved above the borehole by a crane. The hoisting cylinder is extended and then retracted by a winch. The size of the positioning ring matches the size of the drill bit. The positioning ring collects mud, soil, and other waste materials from the bottom of the borehole and the borehole wall into the hoisting cylinder. The waste materials are then lifted to the top section and discharged directionally along the slag discharge cylinder, improving slag discharge efficiency and avoiding the impact of waste materials in the borehole on the subsequent placement of prestressed pipe piles or concrete piles, thus ensuring the quality of subsequent construction.

[0006] The present invention is further configured such that the top section is provided with a lifting lug 1 distributed in a circular pattern, one end of the lifting cable is connected to the lifting lug 1, and the other end is connected to the positioning ring.

[0007] Furthermore, the lifting lug is provided with a wire hole, through which the lifting cable passes and is fixed in a loop by a wire rope clamp.

[0008] Using the above technical solution, the top section is equipped with four sets of circumferentially distributed lifting lugs, and the extension or retraction of the lifting cylinder is controlled simultaneously by four sets of lifting cables, together forming a stable suspension structure. The present invention is further configured such that the lifting cylinder component includes a middle lifting cylinder and a bottom lifting cylinder, both of which are provided with the positioning ring, and the lifting cable is connected to the bottom lifting cylinder.

[0009] Furthermore, the middle hanging cylinder is a hollow conical tubular structure, and the bottom hanging cylinder is a conical barrel-shaped structure with its opening facing upwards.

[0010] Using the above technical solution, channels for collecting soil and slag are formed between two adjacent sets of middle hanging cylinders and between the middle hanging cylinder and the bottom hanging cylinder. The hollow middle hanging cylinder forms a limiting container that wraps around the side of the slag and slag. When the slag and slag in the bottom hanging cylinder accumulate to the cylinder opening, the slag and slag will continue to accumulate along the inner cavity of the middle hanging cylinder, thereby improving the slag discharge efficiency.

[0011] The present invention is further configured such that the winch includes a fixed frame, a motor and a take-up coil mounted on the fixed frame, the output end of the motor controls the rotation of the take-up coil, one end of the lifting cable is connected to and wound around the take-up coil, and the other end is connected to the bottom lifting cylinder.

[0012] Furthermore, the bottom lifting cylinder is provided with a second lifting lug, and the lifting cable is connected to the second lifting lug.

[0013] Furthermore, the winch is symmetrically distributed in the top section, and the bottom lifting cylinder is provided with two symmetrically distributed lifting lugs.

[0014] Using the above technical solution, the lifting cable only acts on the bottom cylinder. During the retraction process, multiple sets of middle cylinders are retracted one by one in conjunction with the force of the bottom cylinder. The top section is equipped with two sets of winches to provide two symmetrical traction points for the bottom cylinder, maintaining the balance of the bottom cylinder during lifting.

[0015] The present invention is further provided that the top surface of the top section is provided with a lifting ring for connecting an external crane.

[0016] Using the above technical solution, the top section is equipped with two or more sets of lifting rings, which are used to connect to an external crane to realize the rapid lifting of the entire slag discharge guiding device.

[0022] Combination Figure 2 As shown, in this embodiment, the top section 1 is provided with circumferentially distributed lifting lugs 9. One end of the suspension cable 3 is connected to the lifting lug 9, and the other end is connected to the positioning ring 7. The lifting lug 9 is provided with a wire hole 10. The suspension cable 3 passes through the wire hole 10 and is fixed in a loop shape by a wire rope clamp 11. The top section 1 is provided with four sets of circumferentially distributed lifting lugs 9, and the extension or retraction of the suspension cylinder 2 is controlled by the four sets of suspension cables 3 simultaneously, together forming a stable suspension structure. In this embodiment, the lifting cylinder 2 includes a middle lifting cylinder 12 and a bottom lifting cylinder 13. Both the middle lifting cylinder 12 and the bottom lifting cylinder 13 are provided with the positioning ring 7. The lifting cable 5 is connected to the bottom lifting cylinder 13. The middle lifting cylinder 12 is a hollow conical tubular structure, and the bottom lifting cylinder 13 is a conical barrel structure with the opening facing upward. A channel for collecting soil and slag is formed between two adjacent sets of middle lifting cylinders 12 and between the middle lifting cylinder 12 and the bottom lifting cylinder 13. The hollow middle lifting cylinder 12 forms a limiting container that wraps around the side of the slag and slag. When the slag and slag in the bottom lifting cylinder 13 accumulate to the cylinder opening, the slag and slag will continue to accumulate along the inner cavity of the middle lifting cylinder 12, thereby improving the slag discharge efficiency.

[0023] Combination Figure 3 ,4 As shown, in this embodiment, the winch 4 includes a fixed frame 15, a motor 16 and a take-up coil 17 mounted on the fixed frame 15. The output end of the motor 16 controls the rotation of the take-up coil 17.

The top section 1 is provided with two or more sets of lifting rings 18, which are used to connect to an external crane to realize the rapid lifting of the entire slag discharge guiding device.

[0025] The working principle of this utility model is as follows: after the drilling rig completes the drilling, the top section 1 is moved above the borehole by the crane. The motor 16 controls the winding reel 17 to rotate and release the lifting cable 5, so that the lifting cylinder 2 extends into the borehole one by one under its own weight. An annular channel is formed between adjacent lifting cylinder 2. When the motor 16 controls the winding reel 17 to rotate in the opposite direction and retract the lifting cable 5, the lifting cylinder 2 retracts under the action of the lifting cable 5. The mud, soil and other waste materials at the bottom and wall of the borehole are collected into the lifting cylinder 2 through the annular channel, and the waste materials are lifted to the top section 1 and discharged in a directional manner, thereby improving the slag discharge efficiency.
