Abstract
The utility model discloses a flexible fixing device of a cable pile head. The flexible fixing device comprises two same semicircular clamping plates, wherein the two sides of the semicircular clamping plates are respectively welded together with steel plates; each steel plate is uniformly provided with through holes. The flexible fixing device disclosed by the utility model is reasonable and reliable in structure and is convenient to operate and maintain; an alternating load and shearing stress, which are born by a cable, can be effectively eliminated; the service life of the cable is prolonged and the fault rate is reduced; the cost is lowered.
Description
Technical field
The utility model relates generally to the hoisting crane field, relates in particular to a kind of cable pile crown flexible fixing device.
Background technology
The power supply of quaternion crane is finished by cable drum and current collection slip ring by the three-phase and four-line Plastic-sheathed Cable, because the traveling gear of transfer crane belongs to workability mechanism, cable needs at ground pile crown place constantly back and forth to travel, cause cable in the frequent break-in bending in former anchor fitting place, bear reverse load and shearing stress.Get off for a long time, make sweep produce tired consequently stress and concentrate, the disconnected burst phenomenon of final cable happens occasionally.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of cable pile crown flexible fixing device is provided, make the suffered rigid curved of cable become flexible bending, increase the active area of cable institute holding capacity simultaneously, increased the service life of cable greatly, reduce equipment failure rate, reduce the labour intensity of service worker.
The utility model is achieved through the following technical solutions:
A kind of cable pile crown flexible fixing device is characterized in that: include two identical semicircle clamps, the both sides of semicircle clamp are welded with steel plate respectively, are evenly distributed with through hole on each steel plate.
Described cable pile crown flexible fixing device is characterized in that: described two semicircle clamps are one by some bolt that run through the through hole on the described steel plate, and the diameter of semicircle clamp is not less than the diameter of cable.
Described cable pile crown flexible fixing device is characterized in that: the through hole in the bottom of each steel plate is connected with galvanized chain by shackle, and the other end of galvanized chain links to each other with the reservation ear seat on ground by shackle.
Principle of the present utility model is:
Cable is when crossing the pile crown position, and the cable that semicircle clamp clamps and ear seat be in-line all the time.Cable clamps the position and only bears pulling force, does not produce reverse load and shearing stress, though the cable that clamps the lower end, position is just very little to the injury of cable because its bending spring is bigger crooked back and forth, can play the effect of protection cable.
The beneficial effects of the utility model are:
The utility model is rational in infrastructure, reliable, and operation and maintenance is convenient, can eliminate reverse load and the shearing stress that cable bears by actv.; Play and prolong cable service life, reduce fault rate, reduce the effect of cost.
Description of drawings
Fig. 1 is main TV structure scheme drawing of the present utility model.
Fig. 2 is plan structure scheme drawing of the present utility model.
Fig. 3 is the structural representation of ear seat.
The specific embodiment
As shown in Figure 1, 2, a kind of cable pile crown flexible fixing device includes two identical semicircle clamps 1, and the both sides of semicircle clamp 1 are welded with steel plate 2 respectively, are evenly distributed with through hole 3 on each steel plate 2.
Two semicircle clamps 1 are one by some bolt that run through the through hole 3 on the described steel plate 2, and the diameter of semicircle clamp 1 is not less than the diameter of cable.
The through hole 3 in the bottom of each steel plate 2 is connected with galvanized chain by shackle 4, and the other end of galvanized chain links to each other with the reservation ear seat 5 on ground by shackle.
Embodiment
The steel pipe of internal diameter 45mm external diameter 54mm length 202mm is cut away half; the steel plate with holes of the every throat depth 6mm of section place, length 202, wide 50; cable is wrapped protective cover (tire inner tube skin) to be clamped with this clamp; the nethermost hole of steel plate is connected with galvanized chain with shackle, and the lower end of chain links to each other with the reservation ear seat 5 usefulness shackles on ground.Cable is tied up with protective cover in the lower end that clamps the position, avoids cable and chain friction impaired.
