Abstract

The invention discloses a self-locking type slide trolley. The self-locking type slide trolley comprises a slide trolley body and a hook connected with the slide trolley body. The slide trolley body comprises side plates. A pulley shaft is arranged between the centers of the side plates. Pulleys are arranged on the pulley shaft. A protrusion part is arranged on the outer side of the connection position of the hook columnar part and the hook-shaped part. A safety buckle is hinged to the protrusion part. The lower end of the slide trolley body is provided with a derailing-proof device through which the pulleys of the slide trolley body are prevented from slipping off from a slide rope. By means of the self-locking type slide trolley, the technical problem that the hook is liable to slip off is solved. In addition, the lower end of the slide trolley body is provided with a derailing-proof device through which the pulleys of the slide trolley body are prevented from slipping off from a slide rope, and the slide rope penetrates through a limiting gear, so that even if the slide rope slides drastically, the phenomenon of derailing is avoided due to limiting of the limiting gear. Therefore, the safe and reliable operation of the slide trolley body is ensured fundamentally.

Description

[0001] The patent application of the present invention is a divisional application of the invention title "a derailment-proof self-locking tackle". The original application date is April 25, 2014, and the application number is 2014101713909. technical field [0002] The present invention relates to tackle. Background technique [0003] The block is an important construction tool in the electric power department, and it is often used in operations such as setting out and lifting. The electric power sector generally uses small and medium-sized hook blocks. Because the hook is open, the phenomenon that the hook falls off easily occurs during use. In addition, due to the continuous motion of the sliding rope during use, the sliding rope is easy to break away from the pulley of the block, thus there is a greater potential safety hazard. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a self-locking block, which solve...
