Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a lifting mechanism for a sampling robot. Background Technology

[0002] In this technical field, particularly in roadway sidewall sampling operations in environments such as mines and tunnels, traditional methods primarily rely on manual labor using tools such as pneumatic picks. Operators need to chisel out trenches of specific dimensions in designated sampling areas by hammering the sidewalls. This manual sampling method has many drawbacks: firstly, the work efficiency is extremely low, often taking 5 to 6 hours to chisel a single trench; secondly, workers often need to work at heights, posing significant safety hazards; furthermore, the labor intensity is high, and the sampling quality is easily affected by human factors and the condition of the tools.

[0003] To address these challenges, the adoption of sampling robots to replace manual labor has become an inevitable trend in the industry. Sampling robots are typically equipped with drilling devices, requiring a reliable lifting mechanism to precisely position the drilling devices to the sidewalls or even the top of the tunnel for sampling operations.

[0004] Currently, most lifting mechanisms used in such robots employ hydraulically driven cylinders for lifting, as pneumatic, rack and pinion, and other drive structures lack sufficient driving force. However, this conventional lifting mechanism has an inherent technical drawback: to achieve sufficient lifting stroke, the cylinder itself and its piston rod require a considerable amount of longitudinal space for extension and retraction. Specifically, in the initial position or retracted state, the cylinder body and the necessary travel space for the piston rod extension make it difficult to lower the base or initial horizontal height of the entire lifting mechanism.

[0005] This deficiency is particularly pronounced during sampling operations at the top of tunnels. Due to the limited space at the top of the tunnel, a lifting mechanism with an excessively high initial height will severely restrict the robot's mobility and working range, and may even fail to effectively lift the drilling device and press it against the roof in low tunnels. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a lifting mechanism for a sampling robot, which solves the technical problem of excessive vertical space wastage in existing lifting mechanisms for sampling robots.

[0007] A lifting mechanism for a sampling robot according to an embodiment of the present invention includes a lifting base, a lifting middle frame, and a lifting top frame that are sequentially overlapped and connected. The inner sides of the lifting base are slidably connected to the outer sides of the lifting middle frame, and the inner sides of the lifting middle frame are slidably connected to the outer sides of the lifting top frame. A transmission mechanism is provided on the lifting base, and the transmission mechanism drives the lifting top frame to move along the height direction of the lifting base. The top of the lifting middle frame and the bottom of the lifting top frame are provided with mutually abutting limit plates, and the top of the lifting base and the bottom of the lifting middle frame are provided with mutually abutting limit plates.

[0008] The technical principle of this utility model is as follows: the equipment that needs to be raised is installed on the lifting top frame, and then the transmission mechanism drives the lifting top frame to rise. Then, because the lifting middle frame and the limiting plate of the lifting top frame abut against each other, the lifting middle frame is also pulled up until the lifting base frame and the limiting plate of the lifting middle frame abut against each other, which is the maximum extension length.

[0009] Compared with the prior art, this utility model has the following beneficial effects: by connecting the lifting base, lifting middle frame and lifting top frame in sequence with the transmission mechanism, the three parts of the lifting base, lifting middle frame and lifting top frame are completely overlapped when retracting, so that the overall height of the lifting mechanism is lower. This solves the technical problem of large waste of longitudinal space in the lifting mechanism of the existing sampling robot.

[0010] Furthermore, the transmission mechanism includes a lifting cylinder and a lifting pulley mounted on the lifting cylinder. A transmission bar is provided between the bottom of the lifting base and the bottom of the lifting top, and the transmission bar is wound around the lifting pulley.

[0011] The lifting pulley, in conjunction with the transmission bar, converts the original thrust of the lifting cylinder into an upward pulling force. The transmission bar is connected to the bottom of the lifting frame, meaning that the force at the top of the lifting cylinder can be applied to the bottom of the lifting frame.

[0012] Furthermore, the sampling robot includes a drilling device, a milling device, and a material suction device. The drilling device and the milling device are both installed on one side of the bottom of the lifting frame. The material suction device has two suction ports, which are respectively connected to the drilling device and the milling device.

[0013] Furthermore, the top of the lifting frame is equipped with a three-way connecting valve mechanism, the three-way of which is respectively connected to the material suction device, the drilling device and the milling device.

[0014] Furthermore, the top of the lifting frame is provided with an annular suction disc on the side corresponding to the drilling device. The annular suction disc has a through hole in the middle for the drilling device to pass through. One side of the annular suction disc is connected to the suction port of the corresponding drilling device.

[0015] Furthermore, the three-way connecting valve mechanism includes a three-way pipe and solenoid valves disposed at the two outlets of the three-way pipe, wherein the solenoid valves are connected to the suction port of the drilling device or the milling device.

[0016] Furthermore, a sliding frame is provided on one side of the bottom of the lifting frame, the sliding frame is slidably mounted on the lifting frame, a drive structure is provided on the lifting frame, the drive structure is connected to the sliding frame, and the drilling device and milling device are mounted on the sliding frame.

[0017] Furthermore, the drive structure includes a drive cylinder and a drive wheel mounted on top of the drive cylinder. The drive wheel is provided with a drive bar, one end of which is connected to the bottom of the lifting frame, and the other end of which is connected to the sliding frame.
