Problems solved by technology

[0005] Both of the above two patents have solved the technical problem that the carrying trolley interferes with the pusher, the trolley, and the pusher at the fork, resulting in jamming and loss of the trolley. However, the above two utility model patents have the following problems:
If the irradiation box stays at the 24KT (travel switch) position at the herringbone rail, and at the same time there is an occupancy signal, a fault of the herringbone rail of the accumulation section will occur, causing the entire system to stop, and the producer has to restore the system. However, it takes a lot of time to restore the system, which greatly reduces the production efficiency.
[0007] 2. The drive chain has a horizontal turn before entering the herringbone rail, and the contact surface between the pusher of the drive chain and the pusher of the trolley is reduced at this turn. When the trolley vibrates slightly, it may cause the pusher of the chain and the trolley to push The head is detached, and the car is lost, which causes the rear irradiation box to hit the front irradiation box, causing the chain motor displacement failure, causing the entire system to stop, and the producer has to restore the system again, which takes a lot of time. Greatly reduced production efficiency
[0008] 3. Due to long-term operation, the push head of the trolley will also be deformed, the height of the push head of the trolley will change, and the car will be lost when the drive chain enters the horizontal turn of the herringbone rail, causing a box collision failure, causing the entire system to stop, and the producer has to restart Restoring the system, and restoring the system takes a lot of time, which greatly reduces production efficiency

Embodiment 1

[0039] Such as Figure 1 to Figure 6 Shown, a kind of accumulative type suspended conveyor herringbone rail push head bridge, comprises base 31, bridge frame 32 and bridge body 33, and described bridge frame 32 is installed on the base 31, and is set between described bridge frame 32 and bridge body 33 Back-moving spring 36 is arranged, and bridge frame 32 is provided with limit screw rod 35, and bridge body 33 is provided with limit hole 34 corresponding with limit screw rod 35, and described bridge body 33 is connected bridge frame by limit hole 34 and limit screw rod 35. 32 is connected, and the bridge body 33 can move up and down on the bridge frame 32 through the action of the return spring 36, the limit hole 34 and the limit screw 35. Base 31 is made of bar-shaped steel plate, and steel plate is about 1 centimeter longer respectively than bridge frame 32 two ends, and base 31 is used for being welded on load rail 1, thereby has realized accurate positioning of the presen...

Embodiment 2

[0042] Such as Figure 4 As shown, in this embodiment, on the basis of Embodiment 1, the bridge body 33 is divided into a connecting part 331, a supporting part 332 and an end part 333. The connecting part 331 is connected with the bridge frame 32 through the limiting hole 34, and the connecting part 331 is connected There is a support portion 332 for supporting the push head 4 of the carrying trolley, and the two ends of the support portion 332 and the connecting portion 331 are connected with an end 333 for the upper and lower bridge body 33 of the push head 4 of the load trolley, and the bridge body 33 is trapezoidal as a whole. In this embodiment, the bridge body 33 is divided into several independent parts, and each part is connected together by welding. As a deformation form of this embodiment, the bridge body 33 can also be integrally formed, and the manufacturer can according to their own requirements. To select the molding method of the bridge body 33.

Embodiment 3

[0044] Such as Figure 4 As shown, in this embodiment, on the basis of Embodiment 2, the end 333 is designed as a slope shape, the angle between the slope surface and the horizontal plane is 10-45°, and the end 333 is set as a slope shape, which is conducive to carrying the push head of the trolley 4. Up and down the bridge body 33, and the angle between the slope surface and the horizontal plane is too small, so that the length of the end 333 is too long, which not only wastes manufacturing materials, but also does not match the length of the driving chain 5 at the horizontal turning of the herringbone rail, which is easy If a failure occurs, if the angle between the slope and the horizontal plane is too large, it will be difficult for the carrying trolley to push the head 4 up and down the bridge body, and it will be easy to block the carrying trolley pushing the head 4, causing the system to stop and reducing the system work efficiency. As a preferred mode, the slope range ...

Abstract

The invention discloses a herringbone rail head pushing bridge of a power and free overhead conveyer, which comprises a base, a bridge frame and a bridge body, wherein the bridge frame is arranged on the base, a restoring spring is arranged between the bridge frame and the bridge body, a limiting screw is arranged on the bridge frame, a limiting hole which is matched with the limiting screw is arranged on the bridge body, the bridge body is connected with the bridge frame through the limiting hole and the limiting screw, and the bridge body is moved up and down on the bridge frame through the restoring spring, the limiting hole and the limiting screw. According to the invention, the base is arranged in a horizontal turning point of a herringbone rail, the problems of trolley loss and box impact caused by that the contact area between a bearing trolley push head and a chain push head is reduced, the trolley is slightly shaken or the trolley push head is deformed are effectively prevented, so that an irradiation box can work stably, automatic shutdown of a system caused by an abnormal reason is avoided, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a product-and-free suspension conveyor used in the irradiation field, in particular to a device for preventing unstable contact between a chain pusher and a trolley pusher at a herringbone rail. Background technique [0002] At present, the accumulative-free suspension conveyor is generally used in the automatic irradiation device in operation in my country. This device is a double-layer track three-dimensional space closed-loop chain conveying system. The upper rail is the traction rail and the lower rail is the load rail. running on a load track. The system is designed with accumulation type herringbone track for automatic surface change. When the suspended irradiation box enters the third accumulating section from the second accumulating section through the face change of the herringbone rail, it can ensure the uniformity of the dose received by the irradiated items. The job is to drive the chain to run forward continuously...
