Description

Elevating hopper guide rope lifting concrete mixer

technical field

The invention relates to a construction machine, especially a small concrete mixer.

Background technique

Existing general-purpose small-sized concrete mixer generally comprises frame, mixing cylinder, large ring gear, feed hopper and lift out hopper. Wherein, the large ring gear is fixed on the outside of the mixing drum, and the motor drives the large gear and the mixing drum to rotate through the transmission mechanism and gears. The concrete mixing material is put into the mixing drum from the feeding end through the feeding hopper for mixing; after the mixing is completed, the controller controls the mixing drum to reverse, and the concrete is discharged from the discharging end of the other end of the mixing drum into the lifting hopper, and the lifting hopper After being hoisted to the corresponding building floor, the concrete is poured into the trolley, and the trolley transports the concrete to the required place. There are usually two ways to lift the hopper to the building floor. One is to use the hoist to lift the hopper through the wire rope, and then manually operate a rope connected to the hopper to control the direction so that the hopper falls to the corresponding floor. The concrete in the hopper is then poured into a trolley and transported to the place where it is needed. In this way, one more person is required to operate the rising/falling of the hopper, which is labor-intensive and poor in safety. The other is a lifting mixer. The lifting hopper of the mixer is lifted by hoisting the hoist and the wire rope, and the rollers on the hopper rise along the vertical lifting track on one side of the mixer. The concrete in the hopper is poured into the trolley and transported to the place where it is needed. Although this method does not require a special person to operate the hopper up/down, the safety is also better. This mode is better useful when building the building below 10 meters, but, when being used to build the building more than 10 meters, the strength of lifting frame declines, and safety also descends, and the installation of lifting frame is also difficult.

Contents of the invention

The object of the present invention is to provide a kind of easy and safe lifting type concrete mixer for hoisting and discharging hopper guide rope.

For reaching above-mentioned purpose, technical scheme of the present invention is:

A hoisting hopper guide rope lifting type concrete mixer, which includes a concrete mixer and a lifting hopper arranged under the discharge port of the concrete mixer, and is characterized in that it also includes:

The forward-leaning triangular lifting frame fixed on the building and lifted out of the hopper;

The hoist installed on the top surface of the frame above the concrete mixer, the outer end of its hoisting wire rope passes through the top pulley and the bucket pulley on the forward-leaning triangular lifting frame in sequence, and is connected with the hoisting end of the hoisting hopper;

Rope guide pipes fixed on the bucket shafts on both sides of the lifting hopper;

Corresponding to the guide rope tube, the guide rope lower positioning device is arranged on the frame on both sides of the hoisting hopper;

Corresponding to the guide rope tube, it is arranged at the upper end of the forward-leaning triangular lifting frame, including a pole, a bucket hook rod, a bucket hook, and a guide rope positioning device arranged at both ends of the pole;

The lower ends on both sides are respectively connected with the lower positioning device of the guide rope, and the upper ends are respectively connected with both ends of the pole of the upper positioning device of the guide rope, wherein the guide rope passes through the guide rope tube and the guide rope groove.

The hopper guide rope lifting concrete mixer with the above structure must be limited by the guide ropes on both sides during the process of lifting the hopper to feed or falling to take the material, so that the bucket shaft that is lifted out of the hopper can be accurately dropped. The shaft seat of the frame or the bucket hook of the forward-leaning triangular lifting frame can safely complete the feeding task. Moreover, the forward-leaning triangular frame is set on the building, which can be improved along with the height of the building. For example, after the second floor is built, the forward-leaning triangular frame is set on the second floor, and the third floor is built. The second floor is located above the third floor. The winch is set on the top surface of the frame and goes with the mixer, taking up little space on the ground. The performance, operation convenience and safety of the concrete mixer are improved.
