Description

Technical Field

[0001] The utility model relates to the technical field of stacker-reclaimers, in particular to a tail car connecting device for a stacker-reclaimer. Background Art

[0002] A stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards for continuous transportation that can both stack and retrieve materials. The tail car is usually called a feed car or a discharge car. It straddles the main conveyor belt and cooperates with the main machine to realize the function of diverting the stacking. The tail car plays a vital role in the transportation of materials by transferring materials from the ground belt to the cantilever belt of the stacker. There are many types of tail cars. The simplest classification method is to divide them into single tail cars, double tail cars and triple tail cars according to the number. Single tail cars are fixed and lifting. Single tail cars are generally supported by 3 sets of wheels on each side and are pulled on the running track by the main machine. The tail car itself does not have any driving mechanism.

[0003] The tail car is rigidly connected to the main machine by a connecting rod. During the long-term stacking process, the traction force on the tail car is unbalanced due to the unstable power of the driving motors of the running devices on both sides of the main machine or the uneven wear of the driving wheels on both sides. At the same time, due to the uneven load-bearing force of the belt on the tail car during material transportation, the connection structure of the tail car is deformed, causing a certain deviation between the tail car and the main machine. At present, manual adjustment is usually used to prevent the tail car from running off, which is difficult, time-consuming and labor-intensive, and delays the construction period.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A tail car connection device for a stacker and reclaimer comprises a connecting rod, a tail car body and a main machine, the tail end of the connecting rod is welded and fixed to the main machine, two parallel driving devices are connected to the two ends of the tail car body, the driving device comprises a servo motor, a ball screw and a ball nut, the servo motor is connected to the ball screw, the ball nut is sleeved on the ball screw, the ball screw and the tail car body are fixed by bolts, and the top end of the connecting rod is bolted and fixed to the ball nut.

[0007] Furthermore, a limiting groove is provided at the top and outer side of one end of the ball screw close to the servo motor, and the limiting groove is locked by a limiting bolt between the ball screw and the tail car body to limit the movement of the ball screw.

[0008] Furthermore, side plates are respectively welded below both sides of the top end of the connecting rod, two threaded holes A are provided at the top of the top end of the connecting rod, and threaded holes A are also provided at the side plates.

[0009] Furthermore, there is a threaded hole B at the top of the ball nut, and threaded holes B are also respectively provided on the left and right sides of the ball nut.

[0010] Furthermore, the connecting rod and the ball nut are bolted and fixed through connecting bolts, threaded hole A, and threaded hole B.

[0011] Furthermore, the connecting rod is made of square steel.

[0012] By setting the driving device, the present utility model utilizes a servo motor, a ball screw, and a ball nut to realize the position adjustment of the connecting rod, which is electrically adjusted, saving manpower and shortening the construction period; at the same time, the connecting rod and the driving device are bolted and fixed, which is convenient for disassembly and maintenance; by setting two driving devices to be separately connected to two connecting rods respectively, the individual adjustment of each connecting rod can be realized, with convenient adjustment and accurate positioning.
