Description

Technical Field

[0001] This utility model belongs to the technical field of drilling equipment and relates to a telescopic auxiliary tower. Background Technology

[0002] The secondary turret is usually connected to the propulsion frame. Due to the connection, the length increases, making transportation very inconvenient. Each time, the secondary turret needs to be disassembled from the propulsion frame before transportation. This process often requires the use of heavy equipment such as cranes for auxiliary operation, which increases the time cost of transportation. In addition, after multiple disassemblies and reassemblies, the reliability of the bolts will be affected. These bolts are prone to loosening or deformation during long-term disassembly and assembly, thus affecting safety. Utility Model Content

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figure 1-8 As shown, this utility model is a telescopic secondary tower, including a first propulsion frame 1, a secondary tower connecting frame 3, a second propulsion frame 4, and a secondary tower 8. A driving component is provided between the first propulsion frame 1 and the second propulsion frame 4. A power head 5 is provided on the first propulsion frame 1. The power head 5 is connected to the secondary tower 8 through the secondary tower connecting frame 3, and the secondary tower 8 is slidably connected to the second propulsion frame 4. Under the push of the driving component, the power head 5 moves downward on the first propulsion frame 1, thereby driving the secondary tower 8 to move downward.

[0025] By using a telescopic secondary tower structure, the power head 5 moves to the lowest end of the first propulsion frame 1, so that the secondary tower 8 coincides with the first propulsion frame 1 and the second propulsion frame 14, thereby shortening the length of the secondary tower 8. This eliminates the need to disassemble the secondary tower 8 during transportation, thus avoiding safety hazards caused by disassembly. In addition, the shortening of the secondary tower 8 also makes the force distribution more uniform, enhances the stress strength of the secondary tower, makes it more stable during transportation, and improves transportation efficiency and convenience.

[0026] The power head 5 is existing technology and is consistent with the power head in application number 2020102640370. The piston rod of the hydraulic cylinder of the power head retracts, driving the bearing seat, the rotating sleeve and the slip seat to move closer to the housing. The inner conical surface of the conical hole of the slip seat moves to the left along the outer conical surface of the slip and applies pressure to the outer conical surface of the slip. Due to the axial restriction of the slip groove, the slip moves radially along the slip groove toward the central axis, thereby clamping the drill bit placed in the central hole of the spindle. The hydraulic motor is started, and the torque is transmitted to the spindle through gear transmission. The spindle drives the drill bit and the slip, slip seat and rotating sleeve to rotate together, so that the drill bit can start drilling. After the drilling is completed, the hydraulic motor is turned off. After the spindle stops rotating, the piston rod of the hydraulic cylinder extends, driving the bearing seat, the rotating sleeve and the slip seat to move away from the housing. The inner conical surface of the conical hole of the slip seat moves to the right along the outer conical surface of the slip. The pressure on the outer conical surface of the slip is unloaded, and the drill bit is released under the action of centrifugal force generated by rotation.

[0027] Preferably, the second propulsion frame 4 is provided with two auxiliary tower support frames 41, which are slidably connected to the auxiliary tower 8 to support and guide the auxiliary tower 8.

[0028] Preferably, the auxiliary tower 8 is provided with a drill bit 6, the lower end of which passes through the power head 5 and moves downward under the drive of the power head 5; the auxiliary tower 8 is provided with an auxiliary frame 7, and the auxiliary frame 7 is provided with an auxiliary ring 71, which is fitted on the outside of the drill bit 6 to assist the drill bit 6 and ensure that the drill bit 6 is concentric.

[0029] Preferably, the power head 5 is provided with a movable seat 51, which is slidably connected to the first propulsion frame 1. The movable seat 51 is provided with a first traction seat 52 and a second traction seat 53. The connection between the first traction seat 52, the second traction seat 53 and the sprocket 21 allows the power head 5 to move downward during the driving process, thereby driving the drill 6 to move downward.

[0030] Preferably, the driving component includes a connecting frame 2, a sprocket 21, a chain 22, and a motor 23; a connecting frame 2 is provided between the first push frame 1 and the second push frame 4, the connecting frame 2 is provided with a sprocket 21 and a motor 23 is installed on the connecting frame 2, the sprocket 21 is fixedly sleeved on the output shaft of the motor 23, the chain 22 is meshed on the sprocket 21, and one end of the chain 22 is connected to the second traction seat 53;

[0031] During operation of motor 23, sprocket 21 is driven to rotate. Since chain 22 is engaged on sprocket 21, chain 22 is pulled to move. The two ends of chain 22 are fixedly connected to the first traction seat 52 and the second traction seat 53 respectively. Therefore, during the movement of chain 22, moving seat 51 is pulled to move, thereby driving the power head to move downward on the first push frame 1 and driving the drill bit to move downward.

[0032] The first push frame 1 is rotatably provided with a second support roller 12; the other end of the chain 22 passes around the second support roller 12 and is connected to the first traction seat 52; the first push frame 1 is also rotatably provided with a first support roller 11 to support and guide the chain 22 and ensure the stable operation of the chain 22.

[0033] By setting a first support roller 11 and a second support roller 12 on the first push frame 1, effective support and guidance are provided for the chain 22. The first support roller 11 ensures that the chain 22 maintains a stable position during transmission, preventing lateral deviation of the chain 22 due to external factors. The second support roller 12 ensures that the chain 22 can smoothly return to the first traction seat 52, forming a closed chain system; this not only enhances the operational stability of the chain 22 but also increases its service life.

[0034] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
