[0024] As mentioned above, the integrated miner, continuous miner and roadheader used in coal mine tunnel mining are usually equipped with an airborne transporter to transport the cut materials to the rear end of the machine in time, so that the subsequent supporting equipment can transport the materials away from the mining face in time. In the process of underground coal mining, when transporting materials to the rear of the mining machine, manual handle control may cause material leakage or the tail of the machine may scrape against the side wall, resulting in a decrease in the production efficiency of the mining work and an increase in safety accidents.
[0025] At least one embodiment of the present application provides a control device for the tail of an airborne conveyor of a mining machinery, the device comprising a detection mechanism and a control mechanism, the detection mechanism being used to detect the swinging state of the conveyor tail in real time and send the detection result to the control mechanism, the control mechanism being used to control the driving mechanism according to the detection result of the detection mechanism, so as to control the swinging direction, angle and speed of the conveyor tail in real time.
[0026] The control device provided by the utility model can effectively control the swinging state of the tail of the conveyor, thereby reducing material leakage and the scraping between the tail and the side wall, and improving the production efficiency and safety of the mining operation.
[0027] The control device provided in the embodiments of the present application is described below through several specific embodiments.
[0028] At least one embodiment of the present application provides a control device for the tail of an airborne conveyor of a mining machinery, the device comprising a detection mechanism and a control mechanism, the detection mechanism being used to detect the swinging state of the conveyor tail in real time and send the detection result to the control mechanism, the control mechanism being used to control the driving mechanism according to the detection result of the detection mechanism, so as to control the swinging direction, angle and speed of the conveyor tail in real time.
[0029] For example, in some embodiments, Figure 1 and Figure 2 As shown, the detection mechanism includes an anti-collision mechanism, a detection mechanism and a rotating device 11; the anti-collision mechanism is fixedly installed below the tail 1 of the conveyor, and the detection mechanism is fixedly installed below the rear end 2 of the nose of the conveyor and is arranged opposite to the anti-collision mechanism, and is used to detect the swing angle and swing speed of the tail of the conveyor in real time; the rear end 2 of the nose of the conveyor and the tail 1 of the conveyor are connected through the rotating device 11, and the detection mechanism is connected to the control mechanism, and is used to send the detected swing angle and swing speed of the tail of the conveyor to the control mechanism.
[0030] For example, in some embodiments, the rotating device 11 includes a rotating shaft and a shaft sleeve.
[0031] For example, in some embodiments, Figure 1 As shown, the driving mechanism includes a swing cylinder 3, a first end 3-1 of the swing cylinder 3 is hinged to the rear end 2 of the conveyor head, and a second end 3-2 of the swing cylinder 3 is hinged to the conveyor tail 1, and the swing cylinder 3 drives the conveyor tail 1 to swing left and right around the rotation axis relative to the conveyor head 2. Of course, the driving mechanism in the utility model can also be other swinging devices, as long as the structure can meet the swinging function of the driving mechanism in the utility model.
[0032] For example, in some embodiments, Figure 3 As shown, there are two swing cylinders, which are symmetrically arranged on both sides of the rear end 2 of the conveyor head and the tail 1 of the conveyor along the first center line 13 of the mining machine.
[0033] For example, in some embodiments, Figure 2 As shown, the anti-collision mechanism includes a right trigger mechanism 4 , a protection mechanism 5 , and a left trigger mechanism 6 . The right trigger mechanism 4 is fixedly connected to the protection mechanism 5 , and the protection mechanism 5 is fixedly connected to the left trigger mechanism 6 .
[0034] For example, in some embodiments, Figure 2As shown, the protection mechanism 5, the right trigger mechanism 4, and the left trigger mechanism 6 are all arc-shaped, and the center of the arc is the rotation center 11-1 of the rotating device 11. The protection mechanism 5, the right trigger mechanism 4, and the left trigger mechanism 6 are all made of high-strength steel.
[0035] For example, in some embodiments, Figure 2 As shown, the protective mechanism 5 is an arc-shaped baffle, and the right trigger mechanism 4 and the left trigger mechanism 6 are two arc-shaped limit plates symmetrically arranged at both ends of the protective mechanism 5. The two arc-shaped limit plates are tightly fitted with the protective mechanism 5, and the end section 6-1 on the side where the two arc-shaped limit plates are close to each other is roughly a wedge-shaped arc transition, and its thickness gradually increases outward to the plate thickness.
[0036] For example, in some embodiments, Figure 2 As shown, the detection mechanism includes a detection control element 7, a detection control element base 8 and a signal feedback cable 9. The detection control element 7 is mounted on the detection control element base 8. The detection mechanism is configured to output an electrical signal by detecting the compression distance after the contact head 10 on the detection control element 7 contacts the left trigger mechanism 6 and the right trigger mechanism 4, and send the collected electrical signal to the control mechanism through the signal feedback cable 9. The compression distance generated after the contact head 10 contacts can range from 1 to 20 mm, and a more preferred range is 2 to 10 mm.
[0037] For example, in some embodiments, Figure 2 As shown, the contact head 10 of the detection mechanism is not in contact with the protection mechanism 5. When the tail 1 of the conveyor swings to the control range, the contact head 10 contacts the arc surfaces of the left trigger mechanism 6 and the right trigger mechanism 4 respectively, wherein the control range can be set to a swing angle of the tail of the conveyor of ±20°-45° centered on the first center line 13 of the mining machinery.
[0038] For example, in some embodiments, Figure 1-3 As shown, the anti-collision mechanism, the detection mechanism and the slewing device 11 are symmetrically arranged along the first center line 13 of the mining machine.
[0039] For example, in some embodiments, Figure 1-2As shown, a conveyor tail control device is installed below the rear end 2 of the airborne conveyor head and the conveyor tail 1 of the integrated mining and anchoring machine, the anti-collision mechanism is welded and fixed to the conveyor tail 1, the left trigger mechanism 6 and the right trigger mechanism 4 are fixed to the protection mechanism 5 by mounting bolts, the mounting plate 12 is welded and fixed to the rear end of the conveyor head, the detection control element base 8 is fixed to the mounting plate 12 by bolts, and the detection control element 7 is installed on the detection control element base 8 by bolts. The detection control element base 8 is designed with a long hole, and the detection control element 7 can be adjusted according to the contact on the detection control element 7. The contact compression distance between the head 10 and the left trigger mechanism 6 and the right trigger mechanism 4 is adjusted, and the detection control element 7 outputs an electrical signal by detecting the compression distance, and transmits the collected signal to the control center of the machine through the signal feedback cable 9. After receiving the feedback signal, the control center outputs instructions through the program, and controls the pressure of the conveyor swing cylinder 3 through the electromagnetic control valve group, thereby controlling the swing angle and swing speed of the conveyor tail to achieve the control of the unloading position of the conveyor tail, thereby reducing the leakage problem of transported materials, reducing the labor intensity of staff, improving work efficiency and reducing the occurrence of safety accidents. The above-mentioned control device is arranged below the conveyor tail 1 and the rear end 2 of the conveyor head, which does not hinder the transportation of materials and can prevent the collision of the rear supporting equipment.
[0040] In summary, the embodiment of the present application provides a control device for the tail of an airborne conveyor of a mining machine, the device comprising a detection mechanism and a control mechanism, the detection mechanism is used to detect the swing state of the conveyor tail in real time, and send the detection result to the control mechanism, the control mechanism is used to control the driving mechanism according to the detection result of the detection mechanism, so as to control the swing direction, angle and speed of the conveyor tail in real time.
