Description

(54) LIFT AND TRANSPORT DEVICE

The invention relates to a lifting machinery industry, namely, boom lifting and transporting devices with hydraulic motors with reciprocating motion and can be used to keep the device from random movement along the track.

The rail grip is known, containing spring-loaded spring-loaded levers connected to a hydraulic plunger fll.

A disadvantage of the known grip is the lack of connection between the position of the boom of the lifting-transport device and the operation of its drive, which reduces the ease of operation of the grip in underground conditions.

The closest solution to the proposed is a lifting-transporting device containing a trolley mounted on a rail track, on which a rotatable boom with a cargo winch is installed on the turntable, as well as a rail grip mounted on a trolley and representing a rotatable spring-loaded arms, connected to the drive of their rotation L2,}.

A disadvantage of the known device is the relatively high labor intensity in preparing the device for operation.

The purpose of the invention is to reduce the labor intensity of preparing the device for operation.

The goal is achieved by the fact that the device is equipped with an eccentric mounted on a rotary boom, a hydraulic cylinder mounted on a turntable, and the drive for turning the arms of the rail grip is a plunger hydraulic actuator communicated with the hydraulic cylinder, the piston of which is kinematically connected to the eccentric.

FIG. 1 shows the proposed device, a general view; in fig. 2 20 the same, top view; in fig. 3 - hydra / cylinder with eccentric, general view; in fig. 4 - rail capture, general view.

Lifting device

25 contains a trolley 1 mounted on the track 2. On the trolley 1 there is a tilted platform 3 on which the boom 4 is located with the cargo winch 5, like a manual one. On platform 3, a retainer b for boom 4 is mounted. On trolley 1, rail clamps 7 are mounted, each of which is a rotatable spring-loaded levers 8 connected to their rotational drive, which is a plunger hydraulic actuator 9 connected by a pipeline 10 to a hydraulic cylinder 11 mounted on the platform 3, the piston 12 of the hydraulic cylinder 11 being kinematically connected with the eccentric 13, fixed on the boom 4.

The lifting-transport device operates as follows.

When the boom 4 is raised to the working position, the eccentric 13 presses on the piston 12, which displaces the working fluid from the hydraulic cylinder 11 and delivers it through the pipeline Yu to the hydraulic actuator 9, which pressures on the levers 8 and closes them on the railheads 2. At the same time the carriage 1 is locked against movement, and the boom 4 is fixed with a lock b in the working position. Then the loading and unloading operations are performed, after which the boom 4 is lowered to the transport position, the eccentric 13 releases the piston 12, the levers 8 return to the initial (transport) position and the lifting transport device moves along the rail track 2 to the next destination. .

The lifting and transport device at raising of arrows: s in transport

the position automatically actuates the rail grip, which increases the convenience of operation and requires less maintenance personnel.
