Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a guiding mechanism in a guiding system of a telescopic mobile conveyor. Background Art

[0002] In recent years, telescopic mobile conveyors have developed rapidly. There is no perfect industry standard for such equipment in China. Such equipment is mainly used for bulk material stacking and distribution in docks, mines, material yards, etc. The characteristics of telescopic mobile conveyors are that the material throwing point can be adjusted from near to far and from low to high. With the walking of the vehicle, a larger distribution range can be achieved. It is flexible to use and has strong adaptability. Figure 1 The throwing point is at the farthest and highest working state. Figure 2 The material throwing point is in the closest and lowest working state.

[0003] The telescopic extension and retraction of the mobile truss of the telescopic mobile conveyor is one of the main functions of this type of equipment. Whether the extension and retraction of the mobile truss is smooth, reliable, and does not deviate, the guide system plays a key role. The guide system includes: an upper guide mechanism, a lower guide mechanism, a bottom guide wheel, and a side guide wheel. When the mobile truss is in the maximum extension state, the upper guide mechanism and the lower guide mechanism will generate a large support reaction force on the mobile truss. The support reaction force will have a great impact on the structural design of the mobile truss. When the support reaction force is more concentrated, it will generate a large local stress on the frame rods of the mobile truss, which is not conducive to the strength and stability design of the mobile truss. In order to reasonably optimize the structural design of the mobile truss, reduce the structural weight of the mobile truss, and then reduce the load design indicators for the fixed truss and the unloading, it is very important to reduce the stress concentration caused by the upper guide mechanism and the lower guide mechanism on the mobile truss; therefore, the utility model proposes a guide mechanism in the guide system of a telescopic mobile conveyor. Summary of the invention

[0004] In order to overcome the large local stress caused by the guide mechanism on the mobile truss. The utility model provides a telescopic mobile conveyor guide mechanism, which uses four double axles to disperse the support of the mobile truss; two adjacent double axles are installed on a group of hangers II, two groups of hangers II are installed on a group of hangers I, hanger I is installed on a fixed truss, and hangers II and hangers I, as well as hangers I and fixed trusses are hingedly installed with pins; when the mobile truss deflects at the guide mechanism due to deflection deformation during the telescopic process, hangers II and hangers I, as well as hangers I and fixed trusses will deflect accordingly at the pin connection. At this time, the four double axles can always maintain good support for the bottom frame of the mobile truss, reducing the local stress of the mobile truss at the guide mechanism; the mobile guide wheels at both ends of the double axles are provided with rims for guiding the bottom frame of the mobile truss to prevent the mobile truss from lateral displacement during the telescopic process. The structural diagram of the telescopic mobile conveyor guide mechanism of the utility model is shown in Figure 8 .

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A telescopic mobile conveyor guide mechanism can effectively reduce the local stress of the mobile truss at the guide mechanism, comprising a mobile truss, a fixed truss, a pin shaft I, a pin shaft II, a hanger I, a hanger II, a bearing seat, a double wheel shaft and bolts;

[0007] Both ends of the double wheel axle are mounted on bearing seats, and the bearing seats are mounted on hanger II by bolts;

[0008] The hanger II is hingedly installed with the hanger I by using a pin shaft II, and the hanger II can rotate around the pin shaft II;

[0009] The hanger I and the fixed truss are hingedly installed by a pin shaft I, and the hanger I can rotate around the pin shaft I;

[0010] When the mobile truss is being extended or retracted, angular displacement will occur at the upper guide mechanism and the lower guide mechanism, causing the hanger I to deflect around the pin shaft I and the hanger II to deflect around the pin shaft II. At this time, the four double axles can always maintain good support for the bottom frame of the mobile truss.

[0011] A lower guide mechanism is provided below the front end of the fixed truss, an upper guide mechanism is provided on the fixed truss above the tail of the movable truss, and bottom guide wheels and side guide wheels are provided in pairs in the middle of the fixed truss. The upper guide mechanism has the same structural form as the lower guide mechanism and is installed symmetrically in the upper and lower parts.

[0012] A preferred technical solution is that movable guide wheels are arranged at both ends of the double wheel axle, and the movable guide wheels are provided with rims for guiding the bottom side frame of the movable truss.

[0013] A preferred technical solution is that two groups of hangers II are installed on each group of hangers I.

[0014] A preferred technical solution is that two double axles are installed on each group of the hangers II.

[0015] According to a preferred technical solution, the hanger I is a steel plate welded structure.

[0016] A preferred technical solution is that the hanger II is made of steel plate.

[0017] The beneficial effects of the utility model are:

[0018] 1. In the utility model, when the mobile truss is being extended or retracted, the four double axles of the guide mechanism of the telescopic mobile conveyor can always maintain good support for the bottom frame of the mobile truss, which can effectively reduce the local stress of the mobile truss at the guide mechanism, further optimize the structural design of the mobile truss, reduce the structural weight of the mobile truss, and thus reduce the load design index for the fixed truss and the vehicle. By further optimizing the overall structure of the telescopic mobile conveyor, the weight is effectively reduced and the cost is saved.

[0019] 2. When the mobile truss of the utility model is being extended or retracted, angular displacement will occur at the upper guide mechanism and the lower guide mechanism of the mobile truss, which will cause the hanger I to deflect around the pin shaft I and the hanger II to deflect around the pin shaft II. The guide wheels at both ends of the double axle are provided with rims for guiding the bottom frame of the mobile truss, which can effectively prevent the mobile truss from lateral displacement during the extension and retraction process.
