Description

Technical Field

[0001] The present invention relates to the technical field of conveying, and specifically to an accumulation type suspension conveyor with an integral lifting trolley capable of running bidirectionally. Background Art

[0002] Currently, traditional accumulation car groups all include a front car group, a rear car group and a connecting rod. The front car group and the rear car group are respectively hinged to the front end and the rear end of the connecting rod, with a complex structure. Moreover, the conversion of the accumulation car group in the accumulation type suspension conveyor is realized through arc tracks, shunting turnouts or merging turnouts. Especially in the painting production line of large workpieces, when the accumulation car group carrying the workpiece needs to turn around, it will occupy a large area. In summary, the main defects of the traditional accumulation type suspension conveyor are: complex structure, large floor area and high cost. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide an accumulation type suspension conveyor with an integral lifting trolley capable of running bidirectionally to solve the problems mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: The suspension conveyor 2 of the workpiece 1 includes a traction device 2C, a conveyor track 3 and an integral lifting trolley 4. The integral lifting trolley 4 includes a vehicle body 4A, traveling wheels 4B, a hanging device 4C and a hook support 6. The traveling wheels 4B, the hanging device 4C and the hook support 6 are all located on the vehicle body 4A). The hanging device 4C is used for hanging the workpiece 1. The traction device 2C includes a traction chain 2C1 and an eccentric pusher 2C2 installed on the traction chain 2C1. The hanging device 4C hangs the workpiece 1, the eccentric pusher 2C2 pulls the hook support 6, and the vehicle body 4A runs on the conveyor track 3 through the traveling wheels 4B. The hook supports 6 installed in a positive and reverse manner at the front and rear ends of the vehicle body 4A both include half hook seats 6A and half support seats 6B located on the left and right sides. When the eccentric pusher 2C2 is located on the left side of the center line of the conveyor track 3, the traction device 2C drives the eccentric pusher 2C2 forward through the traction chain 2C1. At the same time, the eccentric pusher 2C2 hooks the half hook seat 6A at the front end of the left side of the vehicle body 4A to drive the integral lifting trolley 4 forward. When the rear integral lifting trolley 4 touches the front integral lifting trolley 4, the half support seat 6B at the rear end of the left side of the front integral lifting trolley 4 can lift the eccentric pusher 2C2 to disengage from the half hook seat 6A, so that the integral lifting trolley 4 stops moving forward and accumulates at the rear end of the front integral lifting trolley 4. Similarly, when the eccentric pusher 2C2 is located on the right side of the center line of the conveyor track 3, the integral lifting trolley 4 can also accumulate, that is, the suspension conveyor 2 has positive and reverse bidirectional accumulation functions.

[0005] As a further solution of the present invention: the conveyor track 3 includes a trolley track 3A for the operation of the integral sling vehicle 4, a traction chain track 3B for the operation of the traction chain 2C1, and a bracket 3C. The trolley track 3A and the traction chain track 3B are connected into one body through the bracket 3C.

[0006] As a further solution of the present invention: the vehicle body 4A includes a rectangular pipe 4A3, and the hanging device 4C includes a sling.

[0007] As a further solution of the present invention: the conveyor track 3 includes longitudinal tracks 3X located on one side or both sides of the column track 2Y. The suspension conveyor 2 includes a horizontally arranged column track 2Y and a translation track 5. The longitudinal track 3X includes an entry track 3X1 and an exit track 3X2; the entry track 3X1 is the track before the integral sling vehicle 4 needs to enter the translation track 5, and the exit track 3X2 is the track that the integral sling vehicle 4 needs to enter after leaving the translation track 5; the end of the entry track 3X1 includes an auxiliary push head 3X1A, and through the auxiliary push head 3X1A, the hook support seat 6 can be made to enter the set position of the moving track 5C. The translation track 5 includes a translation trolley 5A, a moving track 5C, and a vehicle body traction 5D. The translation trolley 5A runs horizontally on the column track 2Y. The moving track 5C is a component of the conveyor track 3, and the vehicle body traction 5D is a component of the traction device 2C. The moving track 5C is installed on the horizontally translating trolley 5A; the vehicle body traction 5D installed on the moving track 5C can realize the operation of the vehicle body 4A on the moving track 5C, and through the translation track 5, the integral sling vehicle 4 can be converted between the longitudinal tracks 3X.

[0008] As a further solution of the present invention: the vehicle body traction 5D includes a push-pull device 8. The push-pull device 8 includes a push-pull chain 8A and a set of push heads 8B installed on the push-pull chain 8A. The set of push heads 8B includes two one-way push heads 8B1 installed in opposite directions. The one-way push head 8B1 in front of the set of push heads 8B can prevent the hook support seat 6 from rushing forward, and the one-way push head 8B1 behind pulls the hook support seat 6, so that the vehicle body 4A leaves the entry track 3X1 and enters the moving track 5C; or the one-way push head 8B1 behind pushes the hook support seat 6, so that the vehicle body 4A leaves the moving track 5C and enters the exit track 3X2.

[0009] As a further solution of the present invention: the vehicle body traction 5D includes a telescopic push-pull device 9. The telescopic push-pull device 9 includes a telescopic push-pull chain 9A and 2 sets of telescopic push heads 9B installed on the telescopic push-pull chain 9A; when the telescopic push heads 9B retract, it does not affect the operation of the vehicle body 4A on the moving track 5C. When the retractable push head 9B extending rearward pulls the hook support seat 6 to move forward in the moving track 5C for forward operation, the retractable push head 9B extending forward is used to prevent the hook support seat 6 from rushing forward; when the vehicle body 4A needs to move backward in the moving track 5C, the retractable push head 9B at the rear retracts, and the retractable push head 9B extending forward pushes the rear support seat 6C backward, so that the hook support seat 6 leaves the moving track 5C and enters the set position of the longitudinal track 3X; through the translation track 5, the overall lifting vehicle 4 can be converted between different longitudinal tracks 3X without turning around.

[0010] As a further aspect of the present invention: the conveyor track 3 includes a lifting section 7, and the vertical transportation of the overall lifting vehicle 4 can be realized through the lifting section 7.

[0011] As a further aspect of the present invention: the suspension conveyor 2 includes a bi-directional accumulation conveyor 2A in the painting production line 1A for the workpiece 1.

[0012] As a further aspect of the present invention: the workpiece 1 includes a frame 1B in a motor car bogie and an H-frame in construction machinery.

[0013] In summary, in the present invention, the overall vehicle body combines the front vehicle group, the rear vehicle group and the connecting rod in the traditional accumulation vehicle group into an integral structure, and can also realize the conversion of the overall lifting vehicle among several different longitudinal tracks through the same set of translation tracks without turning around. Therefore, its structure is greatly simplified, the floor area is small, and the construction investment is saved.

[0014] Especially in some specific application scenarios, such as when using a cobalt source to perform nuclear radiation on an item, in order to ensure that the radiation dose on each surface of the item is equal, the item must pass through the cobalt source forward and backward. At this time, the advantages of the present invention are more prominent. BRIEF DESCRIPTION OF THE DRAWINGS
