Description

Rotary lifting device

Technical Field

The utility model relates to a hoisting device, specific theory has related to a gyration hoisting device.

Background

A crane, also called a crown block, a gantry crane, or a crane, refers to a multi-action hoisting machine that vertically lifts and horizontally carries heavy objects within a certain range. Conventional hoisting equipment mainly includes hoist engine, hoist, dolly running gear and cart running gear, however, these hoisting equipment usually the structure is huge, and the mechanism is complicated, and during applying workshop goods shelves layering to put, because the space is limited, the hoist can't reach the goods shelves of middle part, consequently, the operation is put to the inconvenient workshop goods shelves of conventional hoist.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims at providing a gyration hoisting device to prior art not enough.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:

a rotary lifting device comprises an upper retainer arranged at the lower part of a crane trolley, a rotary retainer arranged below the upper retainer, a lifting tray in sliding connection with the rotary retainer, and a lifting mechanism arranged at the upper part of the rotary retainer; the upper retainer is provided with a driving motor, and the output end of the driving motor is connected with the upper end of the rotary retainer through a transmission assembly.

Based on the above, the rotary retainer comprises an embedded track type rigid retainer and a connecting flange arranged at the top of the embedded track type rigid retainer.

Based on the above, one side of the lifting tray is provided with the roller retainer, and the roller retainer is provided with the rollers corresponding to the rails of the embedded rail type rigid retainer.

Based on the above, embedded rail type rigid retainer passes the roller retainer sets up, set up two sets of gyro wheels on the roller retainer, two sets of gyro wheels are located respectively embedded rail type rigid retainer's both sides cooperate with the track.

Based on the above, each set of rollers is at least two.

Based on the above, the roller is connected with the lifting mechanism through a chain.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a gyration hoisting device, middle or the goods shelves of bottom are put or the handling in the mainly used workshop, overcome traditional hoist and are used for the limited workshop in space, can't reach the defect of middle part's goods shelves. In the concrete use, the upper retainer is mounted on the lower portion of a crane trolley in a workshop, goods are placed on the lifting tray, the lifting mechanism drives the lifting tray to move upwards along the rotary retainer, and when the goods angle needs to be adjusted, the driving motor is started to drive the rotary retainer to drive the goods to rotate, so that the angle adjustment is carried out, and the goods shelf placing or lifting requirements in the workshop are fully met.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1-3, a rotary lifting device comprises an upper holder 1 mounted at the lower part of a crane trolley, a rotary holder 5 arranged below the upper holder 1, a lifting tray 6 connected with the rotary holder 5 in a sliding manner, and a lifting mechanism 4 arranged at the upper part of the rotary holder 5; the upper retainer 1 is provided with a driving motor 2, and the output end of the driving motor 2 is connected with the upper end of the rotary retainer 5 through a transmission assembly. In particular, the drive motor and the slewing cage can be connected by a transmission assembly conventional in the art, for example: the gear assembly is connected with the upper retainer through a rotary support frame in order to improve the structural stability; the lifting mechanism may be conventional in the art, such as: a hoisting machine.

The rotary lifting device is mainly used for placing or lifting the middle or bottom goods shelves in a workshop, and overcomes the defect that the traditional crane cannot reach the goods shelves in the middle when being used in the workshop with limited space. In the concrete use, the upper retainer is mounted on the lower portion of a crane trolley in a workshop, goods are placed on the lifting tray, the lifting mechanism drives the lifting tray to move upwards along the rotary retainer, and when the goods angle needs to be adjusted, the driving motor is started to drive the rotary retainer to drive the goods to rotate, so that the angle adjustment is carried out, and the goods shelf placing or lifting requirements in the workshop are fully met.

Specifically, the rotary holder 5 includes an embedded rail type rigid holder and a connecting flange arranged at the top of the embedded rail type rigid holder.

Specifically, one side of the lifting tray 6 is provided with a roller retainer 7, and the roller retainer 7 is provided with rollers corresponding to the rails of the embedded rail type rigid retainer.

Specifically, embedded rail mounted rigid retainer passes roller retainer 7 sets up, set up two sets of gyro wheels on the roller retainer 7, two sets of gyro wheels are located respectively embedded rail mounted rigid retainer's both sides cooperate with the track.

Preferably, there are at least two rollers 8 per set.

Preferably, the roller 8 is connected to the lifting mechanism 4 by a chain.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
