Abstract

This invention relates to devices designed to prevent cranes from coming off the end of a track. The purpose of the invention is to increase reliability. In the event of failure of the brakes of the crane moving mechanism 5, the runner wheel 4 slides against the stop 3 mounted on the body 1. In this case, the sides of the wheel 4 interact with the upper parts of the grippers 6, which are mounted on the lateral sides of the body 1 with the possibility of turning around mi grips 6 with the ability to interact with the neck of the rail 2, providing braking. 3 and.

The invention relates to devices designed to prevent cranes from coming off the ends of the tracks.

A deadlock stop for cranes is known, comprising a housing for mounting on the rail head, a stop mounted thereon for interacting with the crane wheel and mounted on the sides of the housing with the possibility of turning around their middle parts the arms with the upper parts for interacting with the crane wheel and with the lower parts mi to interact with the rail neck.

The disadvantage of this deadlock is low reliability.

The purpose of the invention is to increase reliability. .

This goal is achieved by the fact that the second and maximum abutment includes a housing for mounting on the rail head, a support mounted thereon for interacting with the crane wheel and mounted on the lateral sides of the housing with the possibility of turning around their middle parts with the upper parts for interacting with the wheel crane and with the lower parts to interact with the wheel neck, and the body is equipped with restrictive bars mounted on its sides with the possibility of rotation around the vertical axes, the upper and lower hours and the grippers are made horizontal portions, the end portions which are bent in different directions, said end portions of the lower grippers are arranged between limiting straps.

1 shows a deadlock stop for a crane, a general view; figure 2 - section a - a in figure 1; on fig.Z - view B. in figure 1.

The deadlock stop for a crane contains a housing 1 for mounting on the rail head 2, an support 3 mounted thereon for interacting with the wheel 4 of a crane 5, mounted on the lateral sides of the housing with the possibility of turning around its middle parts the clamps 6 with the upper and lower parts for engagement with the neck of the rail 2, the limiting strips 7 mounted on the lateral sides of the body 1 can be rotated around a horizontal axis 8 perpendicular to the longitudinal axis of the body 1, the arms b are rotated around the vertices axles, upper and lower part

6 are made with horizontal sections, the end parts of which are bent in different directions, with the specified end parts of the lower parts of the grippers 6 are located

between the restrictive bars 7,

Dead-end stop for the crane works as follows.

Before starting work, a dead-end stop, comprising body 1, is mounted on the rail head, 2. To do this, it is necessary to rotate the limiting bars 7 installed on the lateral sides of the body 1 with the possibility of rotation around the horizontal axis 8, perpendicular to

the longitudinal axis of the housing 1, preventing arbitrary rotation of the claws 6 around its middle parts, and mounted on the rail head 2. If the limit switches and brakes of the crane movement mechanism 5 fail, the running wheel 4 runs on the mounted 3, and on the housing 1 mass extinguishes the kinetic energy of the moving crane 5. At the same time, the rim of the traveling wheel 4 of the crane 5

interact with the upper parts of the grippers 6, which are mounted on the sides of the housing 1, can be rotated around their middle parts, and the lower parts of the grippers 6 with the neck of the rail 2, providing braking.
