Abstract
The utility model relates to a stores pylon rope skipping prevention device under cable crane sports car, stores pylon include two or polylith bearing plate that set up side by side under the cable crane sports car, establish a pulley between per two adjacent bearing plate both ends respectively, and cable crane hoisting rope walks around two pulleys between per two adjacent bearing plate, welds one baffle parallel with the bearing plate respectively at per bearing plate both ends, and the welding has the baffle between adjacent baffle outside limit, and there is a determining deviation baffle inboard and pulley rim. The utility model discloses can be with cable crane sports car lower stores pylon jack-up wire rope restriction in the pulley grooving, simple structure, safe and reliable.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a adopt the cable to hang to carry out the bridge construction, concretely relates to cable hangs stores pylon rope skipping prevention device under sports car.
Background
The large-span steel arch bridge is usually hoisted by adopting a cable crane. The arch rib of the basket arch bridge is gradually inclined towards the inner side of the bridge, and the arch rib of the butterfly arch bridge is inclined outwards. When adopting the above-mentioned arch rib of cable crane installation, because the fixed setting of cable hoist cable saddle, the sports car walking circuit is unchangeable, and the slope can inevitably appear in the hoisting wire rope of the in-process cable crane sports car stores pylon of lifting by crane lower hanger, and this process easily causes wire rope to jump the rope, and wire rope breaks away from sports car pulley groove promptly, has the potential safety hazard.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a cable crane sports car stores pylon rope skipping prevention device under is provided, eliminates the potential safety hazard.
The technical scheme of the utility model as follows:
the utility model provides a cable hangs stores pylon rope skipping prevention device under sports car, the cable hangs stores pylon under sports car and includes two or polylith bearing plate that set up side by side, establishes a pulley respectively between per two adjacent bearing plate both ends, and the cable hangs two pulleys between per two adjacent bearing plates are walked around to the jack-up rope, its characterized in that: the two ends of each bearing plate are respectively welded with a partition plate parallel to the bearing plate, a baffle plate is welded between the outer side edges of the adjacent partition plates, and the inner side of each baffle plate is spaced from the rim of the pulley.
The utility model discloses can be with cable crane sports car lower stores pylon jack-up wire rope restriction in the pulley grooving, simple structure, safe and reliable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the lower hanging rack of the cable crane sports car comprises two or more bearing plates 1 which are arranged in parallel, a pulley 2 is respectively arranged between two ends of every two adjacent bearing plates, a cable crane hoisting rope 3 bypasses the two pulleys between every two adjacent bearing plates, and a lifting lug is arranged at the bottom of each bearing plate and used for connecting a hoisted object. A partition plate 4 parallel to the bearing plate is welded at two ends of each bearing plate 1 respectively, a baffle plate 5 is welded between the outer side edges of the adjacent partition plates, and a certain distance is reserved between the inner side of each baffle plate 5 and the rim of the pulley 2.
Above-mentioned structure, the baffle can prevent that the jack-up rope from controlling the bounce and breaking away from the pulley groove when the stores pylon inclines down.
Further, the minimum distance between the inner side of the baffle and the pulley wheel rim can be set to be smaller than the diameter of the hoisting rope, so that the hoisting rope is prevented from being separated from the pulley groove outwards in a loose state.
When the novel rope-grinding device is specifically implemented, rubber pads can be pasted on the inner side walls of the partition plates and the baffle plates, and rope grinding is prevented.
Claims (2)
1. The utility model provides a rope skipping device is prevented to stores pylon under cable crane sports car, stores pylon under cable crane sports car include two or polylith bearing plate that set up side by side, establish a pulley between per two adjacent bearing plate both ends respectively, and the cable hangs the lifting rope and walks around two pulleys between per two adjacent bearing plate, its characterized in that: the two ends of each bearing plate are respectively welded with a partition plate parallel to the bearing plate, a baffle plate is welded between the outer side edges of the adjacent partition plates, and the inner side of each baffle plate is spaced from the rim of the pulley.
2. The cable-suspended carrier lower hanger anti-jump rope device of claim 1, wherein: the minimum distance between the inner side of the baffle and the rim of the pulley is smaller than the diameter of the hoisting rope.
