[0009] Further, the trolley pull rod for pulling the trolley is arranged between the front and rear trolleys, and the trolley pull rod is provided with pull rod through holes at both ends; the fixed plate is provided with a threaded hole and a bolt matched with the threaded hole, and the bolt passes through the pull rod through hole to fixedly connect the trolley pull rod with the trolley.

[0010] Further, the number of the screw rods is four, and the screw rods are fixed on the swing support in an upper and lower interval; the number of the semicircle clamps no is three, and the semicircle clamps no are arranged between the screw rods.

[0011] Compared with the prior art, the utility model has the advantages and characteristics that:

[0012] Split structure design: the trolley of the utility model adopts a split structure, and the fixed plate and the seat of hanging are fixedly connected through a fixed bolt. When a certain trolley component is damaged, the entire trolley does not need to be removed from the track, and only the damaged component needs to be replaced. This design greatly reduces the time and labor required for replacing the trolley and reduces the maintenance cost.

[0013] Semicircle clamp design to avoid cable deformation: the cable clamp subassembly includes a semicircle clamp no and a semicircle clamp no. These two parts are symmetrically arranged and can better fit the shape of the cable. The inner side of the semicircle clamp is fixedly provided with a rubber pad, and a plurality of protrusions are arranged in order on the rubber pad. The protrusions can uniformly distribute the clamping force, prevent the cable from deforming during clamping, and prevent the surface of the cable from being damaged.

[0014] Trolley pull rod design, reduce the risk of traction: a trolley pull rod is arranged between the front and rear trolleys, and the two ends of the trolley pull rod are connected with the fixing plates of the trolleys through bolts. This design makes the traction force between the trolleys no longer completely dependent on the cable itself, but is transmitted through the trolley pull rod, effectively reducing the stress of the cable during traction and avoiding the risk of cable breakage. The design of the trolley pull rod makes the traction force more evenly distributed, further improving the stability and reliability of the system. BRIEF DESCRIPTION OF DRAWINGS
