Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a low-height vertical shaft drilling rig for underground construction. Background Technology

[0002] Shaft engineering is widely used in underground development fields such as mining, pumped storage hydropower stations, tunnel ventilation shafts, and shield tunneling for subways and railways. Traditional shaft drilling rigs typically use hoists or large gantry cranes to assemble and move the drill bit. This method not only requires additional hoisting equipment, increasing construction costs, but also significantly hinders the drilling rig's operation inside the tunnel due to height limitations. Furthermore, the traditional drill bit movement method is cumbersome, requiring multiple steps and reducing construction efficiency.

[0003] During tunnel construction, the height of traditional vertical shaft drilling rigs becomes a significant issue due to space constraints. Excessively tall rigs increase construction difficulty and pose safety hazards. Therefore, reducing rig height to adapt to the tunnel construction environment while simplifying drill bit assembly and movement is a pressing problem for those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a low-height vertical shaft drilling rig for tunnel construction. The device adopts two sets of lifting devices. Through the cooperation of the two sets of lifting devices, the vertical shaft drilling rig can be deployed and operated within a limited height, solving the technical problem of reducing the height of the drilling rig and adapting it to the tunnel construction environment.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a low-height vertical shaft drilling rig for underground construction, comprising a base, a drill frame, a crossbeam, a main drive, a short-connected drill rod, a hook, and a drilling bit device. The drill frame includes an outer drill frame, an inner drill frame, a first lifting device, and a second lifting device. The inner drill frame is lifted by the first lifting device, and the crossbeam is lifted by the second lifting device. The height of the main unit is raised by the combined action of the first lifting device and the second lifting device.

[0006] Furthermore, the inner drill frame 11 is mounted on the outer drill frame, and the first lifting device is located outside the inner drill frame, thereby enabling the inner drill frame to slide up and down.

[0007] Furthermore, the second lifting device is installed inside the inner drill frame and connected to the crossbeam, thereby enabling the crossbeam to move up and down.

[0008] Furthermore, a wear-resistant plate, a guide sleeve, and a movable frame are provided between the inner and outer drill frames to prevent wear during slippage and to ensure the verticality of the drill frame.

[0009] Furthermore, the base is placed flat on the ground, and the lower part of the base is provided with a sliding groove and a translation mechanism, which enables sliding along a horizontal track.

[0010] Furthermore, the main drive is mounted on the crossbeam, and the short drill pipe and the hook are mounted below the main drive to support the weight of the drilling bit assembly and drill pipe.

[0011] Furthermore, the drilling apparatus includes a drill bit and a drill pipe.

[0012] Furthermore, the device also includes a robotic arm, which is located on the outside of the inner drill frame to grasp and position the drill rod.

[0013] Furthermore, the first lifting device is a lifting cylinder.

[0014] Furthermore, the second lifting device is a lifting cylinder.

[0015] Furthermore, the translation mechanism is a translation cylinder.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] This utility model discloses a low-height vertical shaft drilling rig for tunnel construction, which employs two sets of lifting devices. Through the cooperation of these two sets of lifting devices, the drilling rig height is significantly reduced, meeting the requirements for installation operations in low-ceilinged caves. By utilizing a translation mechanism and a hook, the drill bit assembly and movement can be directly achieved using the drilling rig itself, eliminating the need for a large gantry crane and saving on hoisting costs.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a low-height vertical shaft drilling rig for underground construction includes a base 1, a drill frame 2, a crossbeam 3, a main drive 4, a short drill rod 6, a hook 7, and a drilling bit assembly. The base 1 is placed flat on the ground, and a sliding groove 8 is provided at the lower part of the base 1. A translation cylinder is connected to the outside of the base 1, and the horizontal movement of the base 1 within the sliding groove 8 is achieved by the extension and retraction of the translation cylinder.

[0024] The drill frame 2 includes an outer drill frame 10 and an inner drill frame 11. The inner drill frame 11 is fitted onto the outer drill frame 10. A first lifting device 12 is provided outside the inner drill frame 11, and the inner drill frame 11 moves up and down on the outer drill frame 10 by extending and retracting the first lifting device 12. A wear-resistant plate 14, a guide sleeve 15, and a moving frame 16 are provided between the inner drill frame 11 and the outer drill frame 10. The wear-resistant plate 14 can prevent sliding wear between the inner drill frame 11 and the outer drill frame 10, and the guide sleeve 15 and the moving frame 16 can ensure the verticality of the entire drill frame 2. A second lifting device 13 is provided inside the inner drill frame 11. The second lifting device 13 is connected to the crossbeam 3, and the crossbeam 3 moves up and down by extending and retracting the second lifting device 13.

[0025] The main drive 4 is mounted on the crossbeam 3 and can move up and down with the crossbeam 3. A short drill pipe 6 and a hook 7 are located at the lower part of the main drive 4 for connecting to the drilling bit assembly. The drilling bit assembly includes a drill bit 18 and a drill pipe 17. During operation, the drill pipe 17 is connected to the short drill pipe 6 to fix the main drive 4 and the drilling bit assembly. A robotic arm 5 is located on the outside of the inner drill frame 11, which grips and aligns the drill pipe 17.

[0026] Workflow: After the drill bit is assembled, the first lifting device 12 of the drilling rig rises to its maximum position, lifting the inner drill frame 11. The second lifting device 13 extends, driving the crossbeam 3 upward until the hook 7 is higher than the upper part of the drill bit 18 by a certain distance. The drilling rig is then pulled directly above the drill rod 17 via the translation mechanism 9. The hook 7 is lowered, changing from an open state to a closed state, gripping the upper part of the drill bit 18. The drilling rig lifts the drill bit 18, translates it to the hole opening position, and lowers the drill bit 18. Because the first lifting device 12 and the second lifting device 13 are used to raise the height of the main unit, the overall height of the drilling rig is lower than that of previous drilling rigs at the same lifting height.

[0027] The above provides a detailed description of a low-height vertical shaft drilling rig for tunnel construction provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
