Description

A chain type vertical continuous hoist

technical field

The invention relates to a hoisting device, in particular to a chain-type vertical continuous hoisting machine, which belongs to the field of logistics machinery.

Background technique

In the commonly used industrial production lines, there are many continuous lifting mechanisms. Currently on the market, in some production lines that need to continuously lift larger products, most of the continuous hoists used use corrugated sidewall conveyor belts as the traction body and the carrier of the goods, while the conveyor belts made of soft materials are used in high-strength conveyor belts. During operation, it is easy to break due to aging, resulting in product damage and high cost of use; and the conveyor belt made of soft materials cannot bear a large load, so it cannot be made into a vertical continuous elevator, which takes up a lot of space.

The patent with the notification number CN202089530 discloses a tooth-cable bucket elevator, which adopts vertical continuous lifting, takes up little space, wears little, and has a long service life. However, this elevator can only lift powder or granules, and its scope of application is small.

Contents of the invention

In order to solve the problems in the prior art, the present invention provides a chain-type vertical continuous hoist with small occupation space, large hoisting load and long service life.

The technical solution of the present invention is: a chain-type vertical continuous hoist, comprising a fixed frame, and a drive frame fixedly arranged in the frame; a lifting mechanism is arranged in the fixed frame, and a The lifting mechanism is connected and drives the driving device that the lifting mechanism works. The lifting mechanism includes a lifting platform and a lifting chain that is connected with the driving device and drives the lifting platform to lift. on the sprocket set composed of wheels; the lifting platform includes a front guide bar and a rear guide bar parallel to each other, and a chain composed of support bars parallel to each other and with equal spacing between the front guide bar and the rear guide bar The supporting plate is one-way hinged between adjacent support rods; the sprocket set includes a lifting part that makes the front guide rod and the rear guide rod be at the same level and rises synchronously, and makes the front guide rod and the rear guide rod in the The return part is on the same vertical plane and descends synchronously, and the transition part connects the lifting part and the return part.

Preferably, the hoisting chain includes an inner hoisting chain and an outer hoisting chain that are parallel to each other and have equal lengths, and the sprocket set includes an inner sprocket set and an outer sprocket set.

Preferably, both the inner hoisting chain and the outer hoisting chain include left and right two synchronized with each other.

Preferably, both ends of the front guide rod are fixedly arranged on the outer lifting chain, and both ends of the rear guide rod are fixedly arranged on the inner lifting chain.

The hoisting chain is used as the main hoisting traction body, with large load and long service life; the carrier is made of a chain pallet composed of one-way hinged and parallel support rods that can only be bent in one direction. When the chain pallet is in the lifting part, the front guide rod and the rear guide rod are on the same horizontal plane. At this time, the chain pallet is in a horizontal state, and the products in production are placed on the chain pallet and transported vertically upwards. Since the chain pallet only It can be bent in one direction, so the horizontal chain pallet will not sag downwards, and the load is stable; when the chain pallet transports the produced products to the highest point, it enters the transition part, and the chain pallet bends and changes direction; when the chain pallet changes direction After finishing, when recovering level and being in the return portion, the front guide bar and the rear guide bar were in the same vertical plane, and the chain supporting plate was in a vertical state at this moment, and returned to the bottom of the hoist. During the whole operation process, the pallet is lifted horizontally, returned vertically, and bends and transitions during the direction change process, so the occupied area is extremely small, and the flat pallet can be used with various containers to lift solid, liquid or even gaseous containers. Products with a wide range of applications. The inner lifting chain and the outer lifting chain are used to lift the front end and the rear end of the chain pallet respectively. The two sets of lifting chains are equal in length to ensure that the front and rear ends of the chain pallet are lifted synchronously, and parallel to each other to ensure the stable operation of the chain pallet.

Preferably, the lifting chain is provided with a tensioning device. When the hoist is used for a long time, the hoisting chain will be deformed due to wear or long-term use, causing the overall length of the chain to become longer. The tensioning device can start the hoisting chain and the chain is always in a tensioned state. During the hoisting process, it will not be damaged due to loose chains. accident.

Preferably, the drive device includes a drive motor and a deceleration mechanism fixedly connected to the transfer shaft of the drive motor, and the deceleration mechanism is connected to the lifting mechanism.

Preferably, the deceleration mechanism is also provided with a one-way locking device and a braking device. The one-way locking device can prevent the lifting chain from running in reverse, and when the geared motor stops or suddenly loses power, the loading pallet will not reverse, ensuring the safety of the conveyed goods.

Preferably, the lifting part is provided with a vibration-absorbing guide rail. Vibration-absorbing rails keep the chain pallet stable and free from wobble during lifting.

Preferably, protective nets are installed on the outer surfaces of the fixed frame and the driving frame. The protective net protects the safety of operators and avoids production accidents.

In summary, the present invention has the following advantages:

1. The one-way curved chain pallet and hoisting chain can make the hoist save space and have a large load capacity at the same time;

2. It can be lifted continuously, and the lifting efficiency is high.
