Problems solved by technology

When the overhead crane breaks down, it needs to stop at the maintenance section for maintenance, and the other overhead cranes continue to operate in production. When the production running overhead crane is close to the inspection section, if there is a "sliding block" phenomenon in the running overhead crane, the slip bracket will touch the inspection section. Slipping wires will pose a risk of electric shock to the construction workers who are overhauling the crane

Embodiment Construction

[0010] Such as figure 1 , 2 As shown, the two ends of the crane guide rail 5 in the crane maintenance section are respectively fixed to the left and right baffles 4 and 6, and the left baffle 4 or the right baffle 6 is hinged with the brake plate 3, and one end of the brake plate 3 is connected to the cylinder 2 The piston rod is hinged, the cylinder 2 is hinged to the side wall of the beam 1, and the crown rail 5 is fixed on the beam 1.

[0011] The cylinder 2 communicates with an air source (not shown in the figure) through a solenoid valve, and the coil of the solenoid valve is connected in series with the normally closed point of the contactor of the crane maintenance section. The contactor in the maintenance section of the crane has power, the normally closed point of the contactor is disconnected, the solenoid valve is powered off, and the cylinder does not operate; the contactor in the maintenance section of the crane has no power, the normally closed point of the cont...

Abstract

The invention relates to a slide-wire partition protection device for a crown-block repair section. The two ends of a crown-block guide rail in the crown-block repair section are respectively fixed at a left baffle plate and a right baffle plate, and a brake plate is hinged to the left baffle plate or the right baffle plate. One end of the brake plate is hinged to a piston rod of an air cylinder, and the air cylinder is hinged to the side wall of a cross beam. The crown-block guide rail is fixed on the cross beam.

Description

technical field [0001] The invention relates to a maintenance protection device for a crane, in particular to a protection device for sliding line partitions in the maintenance section. Background technique [0002] Most of the existing crane power supply is a slipper device (single slipper and double slipper) to take power. When the overhead crane breaks down, it needs to stop at the maintenance section for maintenance, and the other overhead cranes continue to operate in production. When the crane in production operation is close to the maintenance section, if there is a "sliding block" phenomenon in the running crane, the slip bracket will touch the inspection section. Slipping wires will pose a risk of electric shock to construction workers who are overhauling the crane. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention provides a sliding line partition protection device for the maintenance section of the...
