[0002] Multi-functional vehicles used in coal mines are characterized by their versatility and quick-change capability. Typically, one vehicle is equipped with multiple working mechanisms to complete various underground tasks. However, the working capacity of these vehicles varies, and the connection methods and types of mechanisms within the same model series also differ. To a certain extent, they are dedicated to specific purposes, and there are many cases where a particular model is scrapped while its working mechanisms remain intact. This invention patent relates to a quick-connect and self-locking device for the working mechanisms of multi-functional vehicles in the same series used in coal mines, which aims to solve the above problems. The quick-connect part enables the physical connection of the working mechanisms of vehicles within the same series, and the control system enables the hydraulic control and self-locking of the quick-connect part. This not only expands the scope of vehicle use and improves the utilization rate of a single vehicle, but also reduces the purchase cost for coal mines. Summary of the Invention

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] See Figure 1 and Figure 2 A quick-connect self-locking device for the working mechanism of a multi-functional vehicle in a coal mine series includes a switching device body 7. The switching device body 7 includes a first side connected to a power vehicle body 1 and a second side connected to a working mechanism 8. The upper part of the first side of the switching device body 7 is detachably connected to a power vehicle body connecting mechanism 2. The lower part of the first side of the switching device body 7 is provided with a power side insert plate connecting plate 11, which is detachably connected to the power vehicle body connecting mechanism 2. The power vehicle body connecting mechanism 2 is fixedly connected to the power vehicle body 1. The upper part of the second side of the switching device body 7 is connected to the upper round steel of the working mechanism 8, and the lower part of the second side of the switching device body 7 is detachably connected to the working mechanism 8.

[0023] See Figure 1 In some embodiments, the upper part of the first side of the switching device body 7 is provided with a right-angle hook lug 10 that is connected to the round steel of the power vehicle body connection mechanism 2.

[0024] See Figure 1 and Figure 3In some embodiments, a power-side insert plate connecting plate 11 is provided on the lower part of the first side of the switching device body 7. The power-side insert plate connecting plate 11 and the power vehicle body connecting mechanism 2 are provided with corresponding overlapping rectangular holes. A power vehicle body insert plate 3 is passed through the two rectangular holes. The power vehicle body insert plate 3 is driven by the power vehicle body insert plate execution cylinder 4.

[0025] See Figure 2 In some embodiments, the upper part of the second side of the switching device body 7 is provided with a Y-shaped fork lug 9 that can be inserted into the upper round steel of the working mechanism 8 of the mechanism body.

[0026] In some embodiments, a mechanism side insert plate connecting plate 12 is provided on the lower part of the second side of the switching device body 7. The mechanism side insert plate connecting plate 12 and the working mechanism 8 of the mechanism body are provided with corresponding overlapping rectangular holes. The mechanism body insert plate 5 is inserted through the rectangular hole and is driven by the mechanism body insert plate execution cylinder 6.

[0027] Work process:

[0028] S100: In the initial state, when the hydraulic control handle is operated, neither the power body slide plate actuator cylinder 4 nor the mechanism body slide plate actuator cylinder 6 can move, thus avoiding driver misoperation.

[0029] S200: After the pump starts, high-pressure oil passes through the pump outlet P, the high-pressure filter, and the load-sensitive multi-way valve. The load-sensitive multi-way valve is controlled by a hydraulic handle. When the front and rear mechanisms need to be linked, the knob of the pressure control switching valve is in the neutral position. At this time, the manual switching valve needs to be pressed, and the pilot handle can be operated to raise and lower the power body insert plate actuator cylinder 4 and the mechanism body insert plate actuator cylinder 6. The power body connecting mechanism 2 is connected to the right-angle hook lug 10 on the switching device body 7 through the top round steel. Adjust the knob of the pressure control switching valve to the left working position. At this time, press the manual switching valve and operate the pilot handle. The bottom power body insert plate actuator cylinder 4 is activated, and the mechanism body insert plate 5 is inserted downwards into the rectangular hole on the power side insert plate connecting plate 11 and the power body connecting mechanism 2, realizing the connection between the device body 7 and the power body 1. After connecting the switching device body 7 and the power body 1, the control system locks the power side insert plate connecting plate 11 and then checks whether the switching device body 7 and the power body 1 are locked.

[0030] S300: Then adjust the posture of the power vehicle body working mechanism, insert the Y-shaped fork 9 of the device body 7 into the upper round steel of the working mechanism 8 of the mechanism body, adjust the up and down position of the power vehicle body connecting mechanism 2 so that the rectangular hole on the mechanism side insert plate connecting plate 12 on the device body 7 coincides with the rectangular hole at the bottom of the working mechanism 8 of the mechanism body. At this time, turn the knob of the pressure control switching valve to the right working position. Then press and hold the manual switching valve, and at the same time operate the pilot handle to actuate the mechanism body insert plate actuator cylinder 6. The mechanism body insert plate 5 is inserted downward into the rectangular hole, completing the connection between the device body 7 and the working mechanism 8 of the mechanism body. Connect the switching device body 7 and the working mechanism 8. The control system controls the lower part of the second side of the switching device body 7 to lock the connection with the working mechanism 8, and then checks whether the switching device body 7 and the working mechanism 8 are locked.

[0031] In addition, the pressure control switching valve can dynamically adjust the valve core displacement according to the load size, so that the working mechanism 8 of the power car body and the mechanism car body is always in a horizontal state, which can avoid the impact of different road conditions on the strength of the mechanism at the joint.
