DETAILED DESCRIPTION

[0022] In order to make the purpose, 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 part of the embodiments of the present invention, not all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, a multi-stage serial transfer device includes multiple groups of transfer mechanism units 6 that can move by themselves. The multiple groups of transfer mechanism units 6 are connected in series end to end in the length direction. The transfer mechanism unit 6 at the head end is connected to the cutting device, and a distance sensor 1 with the cutting device is set at the connection position.

[0024] The distance sensor 1 is a point-to-point wireless distance measuring sensor. The distance sensor 1 monitors the distance between the transfer mechanism unit 6 at the head end and the cutting device in real time, and transmits the measured distance signal to the data acquisition device. The data acquisition device determines whether the distance between the transfer mechanism unit 6 at the head end and the cutting device is within the appropriate distance based on the distance signal. If the distance is greater than the set threshold, a command signal is sent to make the transfer mechanism unit 6 speed up and follow up. If the distance is less than the set threshold, a command signal is sent to make the transfer mechanism unit 6 slow down.

[0025] A unit workshop docking sensor 2 and a unit workshop distance sensor 3 are set at the docking position of two adjacent transfer mechanism units 6. The unit workshop docking sensor 2 controls the docking position of the two transfer mechanism units, and the unit workshop distance sensor 3 controls the distance between the two transfer mechanism units.

[0026] A bicycle and laneway wall distance measuring device 4 is provided on both sides of the transfer mechanism unit 1 for measuring the distance between the transfer mechanism unit and the laneway wall.

[0027] The tail of the transfer mechanism unit 1 is connected to the transfer belt, and a discharge position measuring device 5 is provided at the connection portion.

[0028] The transfer mechanism unit 1 is provided with a conveying volume monitoring device 8 for real-time monitoring and counting of coal volume.

[0029] The distance sensor 1, the unit workshop docking sensor 2, the unit workshop distance sensor 3, the single vehicle and laneway distance measuring device 4, the unloading position measuring device 5 and the conveying volume monitoring device 8 are respectively connected to the data acquisition device.

[0030] During construction, the specific operation process is as follows:

[0031] S1: A plurality of transfer mechanism units with telescopic functions and capable of moving independently are connected end to end behind the tunneling equipment. The transfer mechanism units move along with the advancement of the tunneling equipment.

[0032] S2: The distance between the front end of the transfer mechanism unit at the head end and the tunneling equipment is measured in real time through a distance sensor. The transfer mechanism unit at the head end maintains an appropriate distance from the tunneling equipment so that the mined coal can be directly transferred to the transfer mechanism unit at the head end.

[0033] S3: Unit workshop docking sensors and unit workshop distance sensors are set at the docking positions of two adjacent transfer mechanism units. The unit workshop docking sensors control the docking positions of the two transfer mechanism units to be correct, and the unit workshop distance sensors control the distance between the two transfer mechanism units to ensure that coal does not fall during transfer.

[0034] S4: The transport volume monitoring device provided on the transfer mechanism unit is used to monitor and count the transported coal volume in real time.

[0035] S5: The distance between the transfer mechanism unit and the lane side is measured in real time by using the bicycle and lane side distance measuring devices set on both sides of the transfer mechanism unit.

[0036] S6: The transfer mechanism unit at the tail is connected to the transfer belt conveyor to transfer the coal to the transfer belt conveyor.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
