Problems solved by technology

[0004] The present invention is mainly aimed at the use of open "I"-shaped steel for the existing cable drag track, which is easy to accumulate dust or ice and snow, causing wheel jamming, the grooves on the left and right sides of the "I"-shaped steel track are at right angles, and when the track is deformed It is easy to cause problems such as wheel jamming, and provide a closed cable trolley that can effectively reduce the backlog of dust, avoid wheel jamming, reduce the friction between the wheel and the track, and facilitate cable trolleys

Embodiment 1

[0028] Embodiment 1: as figure 1 , 2 , Shown in 3 and 4, a closed cable trolley includes a track 01 and a tow trolley slidingly connected to the track, and the trolley trolleys are installed side by side on the track 01. The track is a tubular structure with an open slot 011 at the lower end, and the cross section of the track is a superior arc. The trolley includes a pulley 02, a central shaft 05 that is rotatably connected to the pulley, a cable saddle 03 fixed on the central shaft, and a cable 04 is fixed on the cable saddle 03. Both ends of the central shaft are equipped with pulleys, and the pulleys and the inner surface of the track form a sliding connection through bearings. The cable saddle runs through the open slot and is connected to the middle of the central axis. The inner surface of the track is located on both sides of the open slot as the first arc-shaped surface 012, and the side of the pulley is the second arc-shaped surface 021 matched with the first arc-s...

Embodiment 2

[0030] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 5 As shown, sliding balls 06 are arranged on the second arc surface of the pulley, and the sliding balls are embedded on the surface of the second arc surface. The sliding balls are located on the same surface and this surface is perpendicular to the central axis. touch. One end of the pulley away from the central axis is provided with a guide ball 07, and the guide ball is arranged coaxially with the central axis. Such as Image 6 As shown, the guide ball includes a ball body 071 and a ball seat 072 for the ball body to rotate. The pulley is provided with a guide groove 11 for accommodating the ball seat. The ball seat is slidably connected with the guide groove. The spring is in conflict with the ball seat, and the axis of the guide groove is coaxial with the pulley. Such as Figure 7 As shown, the sliding ball includes a ball body 061 a...

Embodiment 3

[0032] Embodiment 3: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 8 , 9 As shown, the track 01 is in the shape of a ring, and the pulley 02 drives the cable saddle 03 and the cable 04 to make a circular motion along the track. The whole track is surrounded by a ring shape, and the track section is in an arc shape, which can avoid the blockage of the pulley.

Abstract

The invention relates to a festoon walking device, in particular to a closed cable festoon. The closed cable festoon comprises a rail, and multiple festoon dollies in sliding connection with the rail, wherein the rail is a tubular structure provided with an opening groove in the lower end; each festoon dolly comprises pulleys, a center shaft rotationally connected with the pulleys, and a cable saddle fixed on the center shaft, the pulleys are arranged at the two ends of the center shaft and are in sliding connection with the inner surface of the rail, and the cable saddle penetrates through the opening groove and is connected with the middle portion of the center shaft; the inner surface of the rail comprises first arc surfaces positioned at the two sides of the opening groove; and the side surfaces of the pulleys are second arc surfaces fitting the first arc surfaces. The closed cable festoon has such beneficial effects as effective reduction of dust accumulation, prevention of wheel jam, reduction of frictional force between the pulleys and the rail and convenience for cable festoon.

Description

technical field [0001] The invention relates to a trolley running device, in particular to a closed cable trolley. Background technique [0002] Cable trolley is a towing cable system for power supply or communication of large equipment. It mainly includes towing trolley, trolley track and cable saddle under the trolley, and the cable is fixed on the saddle. Existing cable trolleys all adopt cylindrical wheels, and the track adopts "I" steel, and the trolley drags the cable to run on the track. The trolley and the track of this structure are all exposed, and the trolley is walking on the track, that is, the wheels slide in the grooves on the left and right sides of the "I"-shaped steel. The "I"-shaped steel is long and easy to deform. The wheels are prone to jamming, especially in the environment with a lot of dust or the rainy and snowy weather in winter in the north. Dust or ice and snow are easy to accumulate in the grooves on both sides of the "I" steel, and the frequen...
