Two-way deviation rectifying push rod with double input shafts

Abstract

The invention discloses a double-input-shaft bidirectional deviation rectifying push rod for a conveying belt, which is realized through flexible shaft transmission and planetary gear differential guide. The double-input-shaft bidirectional deviation rectifying push rod comprises a shell, a worm gear mechanism, a planetary gear differential structure and a spiral push rod mechanism, wherein the worm gear mechanism, the planetary gear differential structure and the spiral push rod mechanism are arranged in the shell. Compared with a traditional passive hydraulic deviation rectifying mechanism, the conveying belt deviation rectifying frame adopting the double-input-shaft bidirectional deviation rectifying push rod can effectively reduce the manufacturing cost, simplify the structure, achieve all the advantages of a rimless hydraulic deviation rectifying mechanism and enable the application to be wider.

Description

Technical Field

[0001] A mechanical push rod applied to a conveyor belt deviation rectifying frame, specifically a double input shaft bidirectional deviation rectifying push rod. Background Art

[0002] For the automatic deviation rectification of large inclination belt conveyors, the effect of passive hydraulic automatic deviation rectification is relatively good. However, due to its complex structure and high cost, its application limitations are very large, and it is difficult to be suitable for the application of various belts. Summary of the Invention

[0003] The purpose of the present invention is to provide a double input shaft bidirectional deviation rectifying push rod with a simple structure, low cost, and capable of replacing a hydraulic deviation rectifying mechanism.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A conveyor belt double input shaft bidirectional deviation rectifying push rod realized through flexible shaft transmission and planetary gear differential guidance, including a housing. Two screw rod holes are provided on the end face of the housing. A push rod protection tube is provided outside the hole on one side, and a ball eye joint is provided at the end. A hose joint is provided outside the hole on the other side.

[0006] Two flexible shaft access holes are provided on the radial surface of the housing. Threads, set collars, and set nuts are provided outside the holes; a worm is installed inside the holes. A flexible shaft structure hole is provided at the outer end of the worm, which is connected to the axis of the flexible shaft accessed through the flexible shaft access hole.

[0007] The interior of the housing consists of two symmetrical groups of worm wheels, worms, driving bevel gears, driven bevel gears, and a single driven bevel gear shaft, screw nut, and screw rod; the worm wheel is integrally connected with the driving bevel gear and meshes with the worm in the flexible shaft access hole; the middle of the driven bevel gear shaft is a screw nut; a thread is provided in the middle part of the screw rod, and the outer end is connected to the ball eye joint; the ball eye joint at the outer end of the screw rod and the hose joint on the end face of the housing are connected by a telescopic dust-proof sleeve.

[0008] In the double input shaft bidirectional deviation rectifying push rod of the present invention, the combination of the screw nut, screw rod, and ball eye joint is a gear reduction mechanism, and the output shaft is a rocker arm or a cam.

[0009] Compared with the prior art, for the conveyor belt deviation rectifying frame adopting the double input shaft bidirectional deviation rectifying push rod of the present invention, only two transmission flexible shafts are needed to connect it with the power take-off idler rollers on both sides, and all the advantages of the original passive hydraulic deviation rectifying mechanism can be realized, thus saving the original complex accessories such as oil pumps, oil tanks, reversing valves, oil cylinders, pipelines, etc., thereby reducing the structural links and the installation and maintenance costs.
