Description

Detachable automatic tilting material hoist

technical field

The invention relates to a detachable automatic tipping material hoist, which is used for lifting colloidal or liquid substances.

Background technique

Resin concrete is a new kind of anti-corrosion material, which has the advantages of high strength, corrosion resistance and strong adhesion, and is mostly used in corrosion-resistant projects and rapid repair projects. Resin glue replaces the cement in ordinary concrete as the cementitious material. It is a gelatinous substance. Its lifting and unloading cannot be done like aggregate. It is lifted to the designated position by lifting the hopper, and then the discharge port is opened to discharge, which will lead to The material leaks during the lifting process, so it can only be discharged from the upper opening of the hopper in the form of tipping. In addition, the resin compound needs to be mixed with curing agent and other components before being lifted, so the volume and inlet of the hopper must be large enough. In order to improve productivity, the hopper is required to be interchangeable. At present, the lifting and tipping of resin rubber materials requires a feeder to lift the hopper vertically to the designated position, and then at least two people are required to operate the hopper to tip the material, which is laborious and unstable in the lifting process.

The patent number is 201220068307.1, and the Chinese patent titled "a lifting and unloading device" discloses a structure, which is composed of a hopper, a hopper bracket, a guide rail, a steel wire rope, and a limit plate, and the guide rails are symmetrically welded on the hopper bracket , The two sides of the hopper are welded with rollers, and the hopper is clamped on the guide rail through the rollers. The top of the hopper bracket is provided with a fixed pulley, the hopper is connected with the power source through the fixed pulley by a steel wire rope, and one end of the guide rail is provided with a limiting plate. The hopper with the above-mentioned structure can only lift solid materials, but cannot lift colloidal or liquid materials, otherwise it will cause it to spill during the lifting process. And the hopper is fixed in the guide rail by rollers, which cannot realize the convenient interchange of the hopper in each cycle.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a detachable automatic tipping material hoist with reasonable structure, convenient use and labor saving.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: the detachable automatic tilting material hoist includes a hopper, a feeding frame, a winch, a pulley assembly, a limit switch and an inductor, and is characterized in that: a small Vehicle frame and lifting frame, the feeding frame is fixed on the ground obliquely, a support beam is arranged on the back of the feeding frame, a curved track is arranged on the feeding frame, a winch is fixed on the top of the feeding frame, and the lifting frame passes through the front and rear Two pairs of rollers roll in the loading frame, the front rollers of the lifting frame are coaxially installed with the pulley assembly, the rear rollers of the lifting frame are fixed by the support shaft, the small frame is set on the lifting frame through the rotation of the support shaft, and the back of the small frame is equipped with The trolley frame rollers, the trolley frame rollers match the curved track, the trolley frame is also equipped with a hoop device, and the hoop device is equipped with a locking device, and the hopper is fixed on the trolley frame through the hoop device and the locking device , The upper and lower ends of the feeding frame are respectively provided with an upper limit switch and a lower limit switch, and an inductor is also arranged at the lower end of the trolley frame, and the hoist is connected with the pulley assembly through a wire rope. In the present invention, the feeding rack is fixed obliquely on the ground, and the included angle between it and the horizontal plane is preferably 75°, and the included angle can be 55°-90°. The inclined setting of the loading rack can increase the stability of the material lifting process, reduce the power of the lifting power source, and reduce the footprint of the entire equipment. In order to ensure the stability of the feeding rack, a supporting beam is arranged on the back of the feeding rack, and the supporting beam is connected and fixed with the chassis bolts of the main engine of the mixing station. The hoist is aligned with the center of the loading frame to ensure that no additional friction occurs on the wire rope of the hoist. When working, the hoist drives the lifting frame and the trolley frame up along the feeding rack synchronously through the pulley assembly. When reaching the curved track, the rollers on the back of the trolley frame enter the curved track, and the lifting frame continues to go up along the feeding rack until the small After the rollers on the back of the frame enter the bend of the curved track, since the small frame and the lifting frame are connected through the rotation of the support shaft, the small frame with the hopper flips around the support shaft while being lifted upwards. Rise up, and slowly realize the automatic tipping of the hopper until the lifting frame touches the upper limit switch, the hoist stops lifting, and the unloading is completed.

The two sides of the back of the trolley frame according to the present invention are respectively provided with ear plates, the connecting shaft runs through the ear plates, and the trolley frame rollers are respectively provided at both ends of the connecting shaft. The setting of the ear plate can make the trolley frame rollers accurately enter the curved track.

The back of the trolley frame of the present invention is provided with a spacer, and the length of the spacer extends to the back of the lifting frame. Pads are used to prevent the trolley frame from tipping over.

Rolling bearings are arranged at the connection between the trolley frame and the supporting shaft in the present invention. Roller bearings allow the trolley frame to rotate safely around the support shaft.

The hoop device of the present invention is provided with two groups of hoop devices, each group of hoop devices includes a static hoop and two dynamic hoops, and the two dynamic hoops are respectively rotated and arranged at both ends of the static hoop through a hinge. The contact ends of the two moving hoops are provided with locking devices. The dynamic hoop and the static hoop are rotatably connected, and the hopper is easy to disassemble and assemble. With the locking device, the hopper can be firmly held, and it is easy to use and install.

The hopper of the present invention is cylindrical, with an opening at the top, and the size of the hopper matches the size of the hoop device. The hopper of the invention is made of corrosion-resistant materials and has a long service life.

Compared with the prior art, the present invention has the following advantages:

1. The hopper can be easily installed or removed through the locking device on the trolley frame, which has good interchangeability, reduces waiting time and improves labor efficiency;

2. The hopper is cylindrical and has a large enough volume to lift colloidal or liquid materials, and the material can be stirred in the hopper in advance. During the lifting and lowering process, the hopper is held by the hoop, and the process is stable without spilling materials;

3. The small frame hugs the hopper, and after being lifted into the curved track, the hopper can be automatically tipped and unloaded, which greatly reduces labor intensity and saves human resources;

4. Simple structure, reliable performance, automatic operation can be realized in the whole process.
