Abstract

A movable hoist. Relates to water conservancy equipment. The utility model comprises an external tooth rotary support, a base and a driving gear; the external tooth rotary support is fixedly arranged on the trolley; the base is hinged to the top of the external tooth rotary support and used for fixedly bearing lifting equipment; the driving gear is rotatably arranged on the side part of the external tooth rotary support through the driving mechanism and is meshed with the external tooth of the external tooth rotary support. The external tooth rotary support is arranged between the lifting equipment and the travelling trolley, and the rotation of the lifting equipment is realized through the rotation of the driving gear, so that the mechanical injury and the high-altitude falling risk during manual steering are reduced.

Description

Movable hoist

Technical Field

The utility model relates to water conservancy equipment, in particular to a movable hoist.

Background

In the overall design of a ship lock, a hoist is typically used for access door handling. The headstock gear sets up on the dolly, and the dolly moves along the guide rail direction on the track roof beam of portal structure, and the water conservancy access door normally is perpendicular to the channel setting, and the passageway position on channel both sides is placed after the access door is lifted to general needs 90 of rotation, usually is lifted the manual work and is placed on both sides after 90 of rotation.

Disclosure of Invention

Aiming at the problems, the utility model provides the movable hoist which is compact and improves the lifting and placing efficiency and safety of the access door.

The technical scheme of the utility model is as follows: a mobile hoist comprising:

the external tooth rotary support is fixedly arranged on the trolley;

the base is hinged to the top of the external tooth rotary support and used for fixedly bearing lifting equipment;

and the driving gear is rotatably arranged at the side part of the external tooth rotary support through a driving mechanism and is meshed with the external tooth of the external tooth rotary support.

Specifically, the driving mechanism includes:

the speed reducer is fixedly arranged on the side wall of the base, and the output end of the speed reducer is fixedly connected with the driving gear;

and the motor is fixedly arranged on the speed reducer and is connected with the input end of the speed reducer.

Specifically, the hoisting equipment comprises a winch.

Specifically, a special hanging bracket matched with the access door is arranged on a cable of the winch.

Specifically, the trolley horizontally moves on the portal guide rail through a plurality of guide wheels.

The utility model comprises an external tooth rotary support, a base and a driving gear; the external tooth rotary support is fixedly arranged on the trolley; the base is hinged to the top of the external tooth rotary support and used for fixedly bearing lifting equipment; the driving gear is rotatably arranged on the side part of the external tooth rotary support through the driving mechanism and is meshed with the external tooth of the external tooth rotary support. The external tooth rotary support is arranged between the lifting equipment and the travelling trolley, and the rotation of the lifting equipment is realized through the rotation of the driving gear, so that the mechanical injury and the high-altitude falling risk during manual steering are reduced.

The utility model is shown in fig. 1-3; a mobile hoist comprising:

an external-tooth swing support 200, the external-tooth swing support 200 being fixedly provided on the cart 100;

the base 300 is hinged to the top of the external tooth rotary support 200 and is used for fixing bearing lifting equipment;

and a driving gear 400 rotatably provided at a side portion of the external-tooth swing support 200 by a driving mechanism 500 and engaged with external teeth of the external-tooth swing support 200.

When the access door is lifted, the special lifting frame 610 is connected with the access door in advance, and after the lifting equipment is started, the access door is lifted to the target height; by starting the driving mechanism 500, the driving gear 400 is driven to rotate, so that the base 300 can rotate at the top of the external tooth rotary support 200, and after the base is rotated to a set angle, the access door can be placed at a preset position by walking of the trolley 100.

Further defined, the drive mechanism 500 includes:

the speed reducer is fixedly arranged on the side wall of the base 300, and the output end of the speed reducer is fixedly connected with the driving gear 400;

Further defined, the lifting apparatus includes a hoist 600.

Further defined, the cable of the hoist 600 is provided with a dedicated hanger 610 adapted to the access door.
