Description

Hydraulic flip type barrel hoist

Technical field

The invention relates to the technical field of industrial solid waste treatment lifting equipment, in particular to a hydraulic flip type barrel hoist.

Background technique

In the industrial solid waste treatment industry, some high-risk wastes cannot be mixed with the crushed materials to the feeding device. These high-risk wastes should be raised into the feed hopper of more than ten meters high to enter The garbage rotary kiln is incinerated. Prior to this, the barrel loading was carried out by the curved track-turning barrel hoist for the garbage transportation. Due to the structure of the hoist, the hoisting position of the hoisting machine was required to be accurate, and the hoist could not use two strokes. The switch is protected, so accidents often occur, causing the system to stop and repair frequently.

After the bucket of the existing hoist is lifted to a certain height, the stroke switch command is issued, and the failure of the first stroke switch can be performed by the second lane, and the flipping table is pushed by the hydraulic cylinder. The curved track-turning barrel hoist can only be equipped with a travel switch after the bucket is lifted to the specified height. If the travel switch fails, the lift drive will work until the equipment is damaged, resulting in great safety. Hidden dangers and certain economic losses.

The hydraulic turning table comprises a turntable, a turning cylinder, a guiding wheel and a turning bracket. The guiding wheel is arranged in a vertical direction of the turntable, and the guiding wheel is coupled with the guiding rail, thereby driving the hydraulic turning table and the medical trash can to be lifted and lowered; the flipping bracket passes the lateral hinge The shaft rotatably connects the medical trash can on the turntable, and the flip bracket also connects the flip cylinder to obtain the turning power source;

The upper transmission shaft of the lifting chain drives the rotation by the motor, the speed reducer and the upper driven sprocket connected in sequence, thereby driving the lifting chain to rotate;

The motor is connected to the elevated stroke switch of the hydraulic turning table, and the turning cylinder is connected to the flipping switch of the medical trash can.

Further, the number of the guide wheels is four pairs, which are respectively disposed at the top symmetrical position and the bottom symmetrical position in the vertical direction of the turntable.

Further, the inverting bracket is a triangular bracket structure, the first end of which is hinged to the lateral hinge shaft, the second end is enclosed by the openable clamp, and the third end is connected to the bottom of the turntable by a tilting support.

Further, the openable clamp comprises a hoop and a plug, and one end of the hoop is fixed at one end of the flip bracket, and the other end is provided with a jack of a vertical direction, which is inserted into an inverted n-shaped structure, and the inverted n One end of the font structure is inserted into the jack, and the other end is fixed to one end of the flip bracket by a lateral connection portion and a return spring.

Further, the inverting cylinder drives the medical trash can to flip 120-136 degrees by flipping the bracket, thereby tilting and dumping the garbage.

Compared with the prior art, the beneficial effects of the present invention are: the barrel hoist of the present invention, the barrel of the medical trash can is sent to the flip bracket of the hoist by the manual special forklift, the safety door is closed, and the lifting device will be The flip bracket is lifted to the designated position, and then the travel switch sends a signal to cause the hydraulic station of the lift to start working. Under the push of the hydraulic cylinder, the flip bracket is turned over, and when the flip bracket is turned to the position where the drum slides, the limit switch is used. The sending command is stopped, and after the delay time is 2s, the hydraulic cylinder pulls the flip bracket to return to position, and after the return position, the lifting gear starts to descend to the starting position, thereby completing a stroke.

The barrel hoist and the hydraulic flip type barrel hoist of the invention are more suitable for use in the garbage incineration kiln, and the performance is not only stable, but also improves material lifting efficiency and saves cost.
