Description

Technical Field

[0001] The utility model mainly relates to the field of material sample collection and preparation, in particular to a docking device for transporting sample barrels on a transfer trolley. Background Art

[0002] In the field of coal sampling and preparation, a large number of sample barrels need to be transferred and transported between the sampling end and the sample preparation end every day, including transporting full barrels to the sample preparation end. After the sample preparation is completed, the empty barrels are sent back to the sampling end to realize the recycling of the sample barrels.

[0003] In the existing sample barrel conveying process, it is very difficult to dock the sample barrels loaded on the roller conveyor unit on the ground to the roller conveyor unit on the transfer cart. The main reason is that the roller conveyor unit on the transfer cart is the mobile end, and the roller conveyor unit on the ground is the fixed end. Regardless of manual or unmanned driving technology, it is impossible to guarantee that the repeated docking positioning accuracy of the roller conveyor line on the mobile end is controlled within 5-10mm. During the reversing process of the manually driven or unmanned transfer cart, there will inevitably be reversing deviations from the left and right, front and back, and tilt angles. Since these three variables will appear at the same time, the sample barrels are often transported from the fixed end roller conveyor on the ground to the mobile end roller conveyor on the transfer cart. Faults such as poor conveying, barrel jams, and sample barrel deflection often occur, making it impossible to achieve automatic docking and unmanned intervention throughout the process. For example, Chinese patent ZL202122640106.6 discloses a docking transmission device for sample transportation. Although it can be laterally translated to achieve docking and transportation between the transfer trolley and the ground roller conveyor, solving the left-right deviation problem of reversing, if there is a front-to-back deviation during reversing, a wide gap will appear between the docking transmission device and the transfer trolley. During the transportation of the sample barrel, there will be faults such as falling, overturning, and jamming. If there is an angle deviation during the reversing of the transfer trolley, a triangular area gap will appear between the docking transmission device and the roller conveyor between the transfer trolley. During the transportation of the sample barrel, due to the misaligned angle, it cannot be smoothly transported to another roller conveyor, and there will be jamming, over-rotation and other faults. Therefore, the problems of left-right deviation, front-to-back deviation and tilt angle deviation during the reversing of the transfer trolley sample barrel are problems that need to be solved urgently by those skilled in the art.

[0014] As a further improvement of the present invention: a vehicle detection mechanism is provided on the transverse walking mechanism, and the vehicle detection mechanism is used to determine the positioning coordinates of the transfer trolley relative to the docking device during the left and right translation of the transverse walking mechanism.

The device offers exceptional adaptability. The drive of the present invention is simple and reliable, making it less susceptible to the risk of barrel tipping or jamming. Furthermore, the device offers low equipment cost, providing a solid guarantee for unmanned operation throughout the entire sampling process. BRIEF DESCRIPTION OF THE DRAWINGS

It solves the problems of left and right deviation, front and back deviation, and tilt angle deviation when the sample barrel is docked between the roller conveyor at the mobile end of the transfer trolley and the roller conveyor at the fixed end on the ground, and when a manned or unmanned vehicle reverses, the three variables of left and right deviation, front and back deviation, and tilt angle deviation occur. The driving of the docking device in this embodiment is simple and reliable, and is not prone to the risk of barrel overturning or barrel jamming. In addition, the equipment cost is low, and it can provide a solid guarantee for unmanned operation of the entire process in the subsequent sampling and preparation field.

[0027] This embodiment also includes a trolley mounting frame 9, which is connected to the fixed frame 1. Furthermore, in a preferred embodiment, the trolley mounting frame 9 is a fixed gantry frame, which can realize the flipping mechanism of the roller conveyor at the mobile end of the transfer trolley from a 90° vertical state to a 0° horizontal state, and stably and reliably connect to the trolley mounting frame 9.

[0028] In this embodiment, the transverse drive mechanism 2 includes a drive motor 21, a synchronous pulley 22, a synchronous belt 23, and a connecting plate 24. The synchronous belt 23 is connected to the transverse travel mechanism 3 via the connecting plate 24. The drive motor 21 drives the synchronous pulley 22 to move, thereby driving the synchronous belt 23 to move. It should be noted that the transverse drive mechanism 2 can also use a sprocket and chain transmission to drive the transverse travel mechanism 3; or a drive motor and gear rack can be used to achieve the movement of the transverse travel mechanism 3.

[0029] In this embodiment, the transverse traveling mechanism 3 includes a transverse traveling frame and traveling wheels. The traveling wheels are driven by the transverse driving mechanism 2 to move along the guide rails on the fixed frame 1.

[0030] In this embodiment, a vehicle detection mechanism 10 is provided on the transverse walking mechanism 3. The vehicle detection mechanism 10 is used to find the positioning coordinates of the transfer trolley relative to the docking device during the left and right translation of the transverse walking mechanism 3, and then determine the relative offset between the roller line of the transfer trolley and the roller line of the docking device.

[0031] In this embodiment, the conveying mechanism 6 is a roller conveyor, and an adaptive roller 61 is provided on the side where the roller conveyor docks with the transfer trolley, and a rotating return roller 62 is provided on the side where the roller conveyor docks with the rear-end roller conveyor; when the transfer trolley docks with the docking device, the longitudinal walking mechanism 4 drives the roller conveyor to extend and touch the rear end of the vehicle, and the adaptive roller 61 is subjected to resistance, and the inclination angle of the roller conveyor is adaptively adjusted to be consistent with the inclination angle of the vehicle; when the longitudinal walking mechanism 4 drives the roller conveyor back to dock with the rear-end roller conveyor, the rotating return roller 62 is subjected to resistance from the return baffle, and the roller conveyor is adaptively adjusted to be straightened; the rotatable roller conveyor is well solved the problem of tilt angle deviation when the transfer trolley is reversing.

[0032] In this embodiment, the longitudinal travel mechanism 4 is connected to the transverse travel mechanism 3 via a guide rail 11 and a roller assembly 12. The longitudinal travel mechanism 4 is driven to extend and retract forward and backward by the drive assembly 5. The roller assembly 12 moves along the guide rail 11, ensuring that the longitudinal travel mechanism 4 does not deflect during extension and retraction, effectively improving docking accuracy. In this embodiment, the drive assembly 5 utilizes a pneumatic cylinder; in other embodiments, electric cylinders, electric push rods, motors, etc. may also be used. The longitudinal travel mechanism 4 may also be connected to the transverse travel mechanism 3 via a screw-nut mechanism or a synchronous belt mechanism.
