Device for quickly towing explosion-proof switch body

Abstract

A device for quickly towing an explosion-proof switch body comprises a dismounting vehicle base. A moving wheel is installed relatively rotationally on the dismounting vehicle base. The front and the rear of the upper surface of the dismounting vehicle base are connected with a support rod and an adjusting rod respectively. The upper end of the support rod is hinged to a connecting arm. The front end of the connecting arm is fixedly connected with a horizontally arranged lifting support frame. The rear end of the connecting arm is fixedly connected with a pressing rod. The rear end of the pressing rod is fixedly connected with a movable card. The upper end of the adjusting rod is fixedly connected with a dismounting vehicle seat. The adjusting rod is in threaded connection with an upper stopping nut and a lower stopping nut which are arranged correspondingly. The adjusting rod passes through the center of the movable card located between the upper stopping nut and the lower stopping nut. The lifting support frame is in a U shape with a forward opening. The upper surface of the center of the lifting support frame is fixedly connected with a connecting block fixedly connected to the front end of the connecting arm. The pressing rod is in a V shape with an upward opening. An intersection angle between the two sections of the pressing rod is an obtuse angle. The movable card is in a circular or U shape.

Description

technical field [0001] The invention relates to an auxiliary tool for maintenance of an explosion-proof switch, in particular to a fast dragging device for an explosion-proof switch body. Background technique [0002] Among the various switches used in the mine, all the switches used in the mine are Class I explosion-proof switches. The damaged switches should be repaired in the electromechanical equipment repair shop. During the repair process, due to the space limitation of the switch cavity, maintenance personnel repair It is particularly cumbersome to get up, resulting in low work efficiency. Therefore, in order to facilitate maintenance, the switch body is generally taken out of the switch cavity for repair. However, in the process of taking the switch body out, hand injuries are often encountered. not safe. Contents of the invention [0003] The invention aims at the deficiencies and provides a fast dragging device for the explosion-proof switch body which can impro...
