Description

Technical Field

[0001] The utility model belongs to... Background Art

[0002] The full-hydraulic tunnel drill is a drilling device designed specifically for complex environments such as underground mines, tunnel engineering, and rock excavation. It uses a hydraulic system as the main power source to provide high efficiency and precise control, and can perform drilling operations in narrow spaces.

[0003] A ZDY4200LS type crawler full-hydraulic tunnel drill disclosed in Chinese invention patent CN115614052A, before drilling, controls the first servo motor to drive the driving gear to rotate counterclockwise, drives the second circular plate to rotate clockwise by 90° through the transmission of the driving gear and the annular rack, so that the two pairs of first hydraulic cylinders on the second circular plate are respectively located on both sides of the main engine compartment. Then controls the two pairs of first hydraulic cylinders to extend until the support pads at the tops of the two pairs of first hydraulic cylinders respectively abut against the inner walls on both sides of the coal mine tunnel, making the position of the entire crawler full-hydraulic tunnel drill more stable, providing a stable base support for the subsequent drilling operation, and thus ensuring the drilling effect of the entire crawler full-hydraulic tunnel drill in the coal mine tunnel.

[0004] Currently, most hydraulic drills use a crawler mobile platform as their moving component. During the construction process of some underground tunnels, the tunnel drill needs to be disassembled and transported to the construction site for assembly. The traditional crawler tunnel drill has strong integrity and is inconvenient to disassemble. Summary of the Utility Model

Simplifications or omissions may be made in this part, as well as in the abstract and title of the application, to avoid obscuring the purpose of this part, the abstract, and the title. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] To solve the problems existing in the above background art, the utility model adopts the following technical solutions.

[0007] A fully hydraulic underground drill rig mobile platform includes a platform base. A pair of beam frames are assembled on the platform base. Multiple auxiliary wheels are provided at the bottom of the beam frames. A rotating table is assembled on the upper surface of the platform base. The fully hydraulic underground drill rig is assembled on the rotating table. One end of the beam frame is connected with a first connector. The first connector is of a U-shaped structure, and a roller is connected inside the first connector by a rotating shaft. The other end of the beam frame is connected with a second connector. A driver is installed on one side of the second connector. A driving wheel is fixedly sleeved on the driving end of the driver. The driver drives the driving wheel to rotate, and the mobile platform is driven to move in the tunnel through the driving wheel. The fully hydraulic underground drill rig can horizontally rotate on the platform base through the rotating table.

[0008] Preferably, the platform base is of a rectangular structure. Docking beams are integrally connected to the four corners of the platform base. Corresponding connection grooves are symmetrically opened on the inner side of the beam frames. The docking beams are inserted into the connection grooves to complete the assembly of the beam frames and the platform base.

[0009] Preferably, the inside of the platform base is of a hollow structure. A rotating shaft is integrally connected to the lower surface of the rotating table and penetrates through the platform base and extends into the inside of the platform base. A large gear disk is fixedly sleeved on the rotating shaft. A small gear meshing with the large gear disk is provided on one side of the gear disk. The center of the small gear is connected with a motor through a shaft rod.

[0010] Preferably, a plurality of connecting pieces are evenly provided on the lower surface of the beam frame. The connecting pieces are of an inverted U-shaped structure. A rotating shaft is provided inside the connecting pieces.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] (1) In the present utility model, the drill rig and the mobile platform adopt a combined installation structure. Through the combined installation, the device can be easily disassembled. Therefore, during operation, the device can be disassembled first and then transported into the tunnel in sequence and then assembled, which to a certain extent reduces the difficulty of entering the tunnel.

[0016] (2) In the present utility model, the mobile offset can also be disassembled. On the one hand, it enables the mobile platform to reduce its volume and enter the tunnel. On the other hand, it is also convenient for the transportation of the device. Moreover, the assembled mobile platform can also facilitate the maintenance of the device to a certain extent. Since the mobile platform adopts an assembled structure, the components attached to the platform need to be integrally installed, making the platform integrity of this device stronger.

[0017] (3) The drill in the present utility model can move horizontally through the rotating table on the mobile platform, thus meeting the angle requirements of the drill during operation, enabling the drill to have a larger radiation range for exploration when the mobile platform is fixed and stopped; the rotating table rotates by the driving method of a small gear driving a large gear disc, which can decelerate and increase torque. When the small gear drives the large gear disc, the rotation speed of the large gear disc will decrease, but the torque will increase correspondingly. This means that even with a small input power, a large output torque can be obtained through this transmission method, which is suitable for scenarios requiring high torque output. By decelerating and increasing torque, a smaller motor or power source can be used to drive a larger load, thus saving energy and reducing costs.

[0018] (4) The driving of the platform in the present utility model is driven by a driving wheel with ribs on its surface. The ribs on the driving wheel enable the device platform to still have sufficient grip on soft ground. Therefore, in the case of silt in the tunnel, the device can still run smoothly. Moreover, multiple groups of auxiliary wheels are provided on the beam. On the one hand, it can evenly transfer the weight of the drill and its platform to the tunnel. On the other hand, it also further strengthens the friction between the platform and the ground, contributing to the smooth movement of the platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so - called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments. The present utility model provides the following embodiments.

[0028] Refer to Figure 1 and Figure 2 is a structural diagram of a fully - hydraulic mine - tunnel drill moving platform in this embodiment. The moving platform in this embodiment includes a platform base 100. A pair of beam frames 102 are assembled on the platform base 100. One end of the beam frame 102 is connected with a first connector 102b. The first connector 102b is of a U - shaped structure, and a roller 102b - 1 is connected inside the first connector 102b by a rotating shaft. The other end of the beam frame 102 is connected with a second connector 102c. A driver 102c - 1 is installed on one side of the second connector 102c. A driving wheel 102c - 2 is fixedly sleeved on the driving end of the driver 102c - 1. The driver 102c - 1 drives the driving wheel 102c - 2 to rotate. The driving wheel 102c - 2 drives the driving wheel 102c - 2 to move in the tunnel, so that the driving wheel 102c - 2 further drives the moving platform to move. Further, in order to ensure the smoothness of the movement, in this embodiment, a plurality of ribs are arranged at equal intervals in a circular pattern on the driving wheel 102c - 2. The ribs enable the driving wheel 102c - 2 to still have sufficient grip on soft ground, thereby driving the platform base 100 and the beam frame 102 to move. And due to the arrangement of the ribs, the driving wheel 102c - 2 in this embodiment has sufficient friction, so that even when there is silt in the tunnel, it can still ensure that the device can run smoothly.

[0029] Refer to Figure 1, there are multiple auxiliary wheels 102d at the bottom of the beam 102. On the one hand, it can evenly transfer the weight of the full-hydraulic tunnel drill and its moving platform to the tunnel. On the other hand, it also further strengthens the friction between the platform and the ground, which helps the platform move smoothly. A rotating table 101 is assembled on the upper surface of the platform base 100, and the full-hydraulic tunnel drill is assembled on the rotating table 101. The full-hydraulic tunnel drill can rotate horizontally on the platform base 100 through the rotating table 101, so as to meet the angle requirements of the tunnel drill during operation, and make the radiation range that the tunnel drill can explore larger when the platform base 100 is fixed and stopped.

[0030] Refer to Figure 3 and Figure 4 , in order to enable the platform base 100 to be better assembled with the docking beam 100a in this embodiment, docking beams 100a are integrally connected to the four corners of the platform base 100 in this embodiment. Correspondingly, connection grooves 102a are symmetrically opened on the inner side of the beam 102. The docking beam 100a is inserted into the connection groove 102a to complete the assembly of the beam 102 and the platform base 100. After docking, bolts can be used for fixation to prevent the connection between the docking beam 100a and the beam 102 from falling off. Since the device of the present utility model is used in a tunnel and the cross-section of the tunnel is mostly rectangular, the platform base 100 is designed as a rectangular structure in this embodiment.

[0031] Refer to Figure 2 , in order to realize driving the full-hydraulic tunnel drill to rotate horizontally through the rotating table 101, the interior of the platform base 100 in this embodiment is a hollow structure, and a rotating shaft is integrally connected to the lower surface of the rotating table 101 and penetrates through the platform base 100 and extends into the interior of the platform base 100. A large gear disk is fixedly sleeved on the rotating shaft, and a small gear meshing with it is provided on one side of the gear disk. The center of the small gear is connected to a motor through a shaft rod. By driving the small gear to rotate by the motor, the large gear disk is further driven to rotate during the rotation of the small gear. Since the large gear disk is connected to the rotating table 101 through a shaft rod, the rotation of the rotating table 101 is realized. The purpose of using gear drive in this embodiment is that because the tunnel is narrow and the internal space is limited, the device is restricted by the space of the tunnel and its volume will also be limited. Therefore, the volume of the driving components of the device also needs to be correspondingly small. And the small-volume driving components will limit their power. Using the driving method of driving the large gear disk with the small gear can decelerate and increase torque. When the small gear drives the large gear disk, the rotation speed of the large gear disk will decrease, but the torque will increase correspondingly. Even if the input power is small, a larger output torque can be obtained through this transmission method. By decelerating and increasing torque, a smaller motor or power source can be used to drive a larger load.

[0032] Refer to Figure 2, in this embodiment, a plurality of connecting pieces are evenly arranged on the lower surface of the beam 102, and the connecting pieces are in an inverted U-shaped structure. A rotating shaft is arranged inside the connecting piece, and the auxiliary wheel 102d is installed in the receiving groove through the rotating shaft, and the auxiliary wheel 102d protrudes from the receiving groove. On the one hand, the auxiliary wheel 102d can evenly transfer the weight of the full-hydraulic drift drill and its moving platform to the tunnel. On the other hand, it also further strengthens the friction between the moving platform and the ground, which helps the smooth movement of the moving platform. Further, in order to ensure the stability of the moving platform during the operation of the device and at the same time ensure that the driving wheel 102c-2, the roller 102b-1 and the auxiliary wheel 102d can all contact the bottom of the tunnel. Therefore, in this embodiment, when the rib is assembled on the driving wheel 102c-2, the diameter of the driving wheel 102c-2 is equal to the diameter of the roller 102b-1, and when the beam 102 is placed horizontally, the lower surfaces of the driving wheel 102c-2, the roller 102b-1 and the auxiliary wheel 102d are on the same plane.

[0033] It should be noted that the present invention mainly improves the moving platform. Therefore, the full-hydraulic drift drill can adopt the existing technology. In order to make the technical solution of the present utility model complete, this embodiment briefly discloses the full-hydraulic drift drill. Specifically, the full-hydraulic drift drill is composed of a drill bit drill rig, a hydraulic system, a control system, a propulsion system and a rotary system.

[0034] The above content further elaborates on the present utility model in combination with specific implementation manners. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present utility model.
