The device mainly comprises a middle base frame body, a connecting block, a pin shaft A, a pin shaft B, a pin shaft C, a vertical cylinder, a sliding seat, a sliding shoe, a connecting seat, a pin shaft D and a horizontal cylinder. The connecting seats are fixed on two sides of the middle base frame body through bolts, cylinder rods of the vertical cylinders are connected with the connecting seats through the connecting blocks, cylinder bottoms of the vertical cylinders are connected with the sliding seats, and the sliding seats are connected with the horizontal cylinders and arranged in sliding ways of the sliding shoes.

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mine underground fully mechanized working face super long stroke belt self -moving tail, concretely relates to a super long stroke belt self -moving tail middle base frame that can move horizontally. BACKGROUND

[0002] With the progress of science and technology, improving the coal mining efficiency becomes the key direction of the iterative development of coal machine products, but the stroke of the traditional belt self -moving tail is generally 2.7 meters, and the whole fully mechanized mining equipment needs to be frequently stopped to carry out the dismounting operation of the belt conveyor middle frame in the coal mining process, which wastes the effective production time and reduces the coal mining efficiency. The stroke of the super long stroke belt self -moving tail can reach 10 meters, which can effectively reduce the number of dismounting the belt conveyor middle frame, and further reduce the number of shutdown of the fully mechanized mining equipment, and improve the coal mining efficiency. In the process of horizontal movement of the whole machine, the head end frame and the tail end frame of the super long stroke belt self -moving tail are extended, and the whole machine should be completely away from the ground, but the middle base frame of the device cannot be away from the ground sometimes because of excessive deflection, and "waist collapse" occurs, which can cause the device to be unable to move horizontally in serious cases. SUMMARY

[0012] In the figure: 1, intermediate base frame body, 2, connecting block, 3, pin shaft A, 4, pin shaft B, 5, pin shaft C, 6, vertical cylinder, 7, sliding seat, 8, sliding shoe, 9, connecting seat, 10, pin shaft D, 11, horizontal cylinder. DETAILED DESCRIPTION

[0013] The installation process is as follows: first, symmetrically install connecting seat 2 on both sides of intermediate base frame body 1 through bolts, then connect the cylinder rod of vertical cylinder 6 with connecting block 9 together through pin shaft B 4, put connecting block 9 and vertical cylinder 6 into the cylinder sleeve of connecting seat 9 from the upper side of connecting seat 9, and connect connecting block 1 and connecting seat 9 together through pin shaft 3. Then put horizontal cylinder 11 into sliding shoe 8, and make the extension length of horizontal cylinder 11 be half of its stroke, slide sliding seat 7 along the slide of sliding shoe 8, connect horizontal cylinder 11 and sliding seat 8 together through pin shaft D 10, and finally connect sliding shoe 8 and the cylinder bottom of vertical cylinder 6 together through pin shaft C 5, so as to ensure that the center line of sliding shoe 8 coincides with the center line of intermediate frame body.

[0014] The working process is as follows: during the horizontal movement of the whole machine of the self-moving machine tail of the super-long stroke belt, the telescopic action of vertical cylinder 6 and horizontal cylinder 11 of the utility model is synchronous with the original vertical cylinder and horizontal cylinder of the whole machine, and the specific horizontal movement process is as follows: when the whole machine moves horizontally, vertical cylinder 6 of the utility model extends together with the original vertical cylinder of the whole machine, intermediate base frame body 1 leaves the ground, horizontal cylinder 11 of the utility model moves the base frame in the required direction together with the original horizontal cylinder of the whole machine, vertical cylinder 6 and intermediate base frame body 1 and sliding seat 7 move in the predetermined direction along sliding shoe 8 as the fulcrum. Operate vertical cylinder 11 to make intermediate base frame body 1 fall on the floor of the crossheading, and make sliding shoe 8 leave the floor. Operate horizontal cylinder 11 to make sliding shoe 8 return to the middle position. If the distance to be adjusted is large, the above process can be repeated until the required moving distance is reached. When the conveying belt of the intermediate section of the self-moving machine tail of the super-long stroke belt deviates to one side, the corresponding vertical cylinder 6 can be operated to lift or correct the corresponding side of the base frame until the conveying belt returns to the normal position.
