Description

Chain deviation preventing device of lifting machine for dust remover

Technical Field

The utility model belongs to the technical field of dust collecting equipment part technique and specifically relates to a chain off tracking device is prevented to lifting machine for dust remover.

Background

Traditional dust remover lifting machine adopts double lift chain to hang the mode that promotes the hopper and go up and down together to promote the material mostly, this kind of mode of promotion is generally that the chain drive on upper portion adopts the motor to drive driving sprocket and rotates, and the chain of lower part then adopts unpowered sprocket feed, but this kind of mode has an drawback, in case just in case driven sprocket is blocked, the chain is just pushed out very easily and the off tracking appears, lead to the lifting machine to break down, just need shut down and overhaul, the work efficiency of dust remover lifting machine has obviously been influenced.

Disclosure of Invention

The utility model aims at providing a chain off tracking device is prevented to lifting machine for dust remover to above-mentioned condition, the device makes the improvement to the lifting machine among the dust pelletizing system now, can effectively prevent the emergence of the chain off tracking condition, and stability is good, and the maintenance cycle is long.

The utility model has the following concrete scheme: the utility model provides a chain off tracking device is prevented to lifting machine for dust remover, includes driving shaft and driven shaft, is equipped with two driving sprocket on the driving shaft side by side, and the winding is equipped with the circulation and promotes the chain on every driving sprocket, and a plurality of promotion hoppers are equipped with between the two circulation promotion chains, promote the hopper and go up and down along with the marcing of circulation promotion chain, and the one end and the outside driving motor transmission of driving shaft are connected, be equipped with on the driven shaft and prevent the off tracking cylinder, the both ends of preventing the off tracking cylinder are equipped with the off tracking guardrail of preventing that the frustum of a cone is described, and the lower part of two circulation promotion chains is.

Further, in the utility model discloses in the vertical swing joint separately has a hoisting screw in the both ends of driven shaft, and hoisting screw's lower extreme passes through the round platform and holds in the palm, and the upper end threaded connection of every hoisting screw has a transverse connection pole, and transverse connection pole and the frame fixed connection of dust remover lifting machine still overlap on every hoisting screw and are equipped with a compression spring, and compression spring's upper end top is on transverse connection pole, and compression spring's lower extreme withstands the driven shaft.

Further, in the utility model discloses in the hoisting screw top still is equipped with the pivoted round cap of being convenient for.

The utility model improves the original driven chain wheel into the anti-deviation roller structure with the anti-deviation guardrail, so that the dust removing equipment without the condition that the circular lifting chain is blocked to fall off and deviate can not be shut down and maintained, and the maintenance period is greatly prolonged; simultaneously the utility model discloses a prevent driven shaft at off tracking cylinder both ends passes through compression spring flexonics, not only can realize promoting the effective tensioning of chain to the circulation, owing to compression spring's elastic buffer effect, is favorable to preventing the emergence of the off tracking phenomenon of chain more moreover.

Drawings

FIG. 1 is a schematic diagram of a prior art lifting device;

fig. 2 is a schematic structural diagram of the present invention.

In the figure: the device comprises a driving chain wheel 1, a circulating lifting chain 2, a lifting hopper 3, a circular cap 4, a transverse connecting rod 5, a compression spring 6, a driven shaft 7, a hoisting screw 8, a deviation-preventing guardrail 9, a deviation-preventing roller 10 and a circular table 11.

Detailed Description

Referring to fig. 1-2, the utility model relates to a chain off tracking device is prevented to lifting machine for dust remover, including driving shaft and driven shaft 7, be equipped with two driving sprocket 1 on the driving shaft side by side, around being equipped with circulation promotion chain 2 on every driving sprocket, a plurality of promotion hoppers 3 are equipped with between the two circulation promotion chains, promote the hopper along with the circulation promote advancing and go up and down of chain, the one end and the outside driving motor transmission of driving shaft are connected, be equipped with on the driven shaft and prevent off tracking cylinder 10, prevent that the both ends of off tracking cylinder are equipped with the off tracking guardrail 9 of preventing of circular cone form, the lower part of two circulation promotion chains is around installing on preventing the off tracking cylinder.

Further, in this embodiment the both ends of driven shaft vertical swing joint has a hoisting screw 8 separately, and hoisting screw's lower extreme holds in the palm through round platform 11, and every hoisting screw's upper end threaded connection has a transverse connection rod 5, and transverse connection rod and dust remover lifting machine's frame fixed connection still overlap on every hoisting screw and are equipped with a compression spring 6, and compression spring's upper end top is on transverse connection rod, and compression spring's lower extreme withstands the driven shaft.

The hoisting screw is actually provided with threads at the upper half part, and the polished rod at the lower half part and the fixed round table support the driven shaft, so that the compression spring can be adjusted by rotating the hoisting screw, and the adjustment can also be carried out by mounting a nut on the hoisting screw.

Further, in this embodiment, the top end of the hoisting screw rod is further provided with a round cap 4 convenient to rotate.

The utility model provides a prevent off tracking guardrail and make into frustum of a cone shape and as far as possible high a bit, the circulation promotes the chain just so and just is blocked also can not slide to the outside at the operation in-process, and the frustum of a cone form on both sides prevents that the off tracking guardrail has the characteristic that promotes chain automatic centering with the circulation, and only need this moment prevent that the off tracking guardrail adopts the material of wear-resisting high strength high rigidity to make just can.

The tension or relaxation adjustment of the deviation-preventing roller in the embodiment is realized by adjusting the hoisting screw rod, and the specific operation is as follows: the hoisting screw rod is driven to rotate through the twisting of the round cap, so that the compression spring can be compressed or loosened, the compression spring can compress or loosen the driven shaft a little, and the tensioning or loosening of the anti-deviation roller is realized.
