Abstract

The invention discloses a special sling for hoisting a steel rail. The special sling comprises two hook plates in bilateral symmetry, lifting holes are formed in the upper ends of the hook plates, hook heads, which can be used for clamping the steel rail, are arranged on the lower ends of the hook plates, the two hook plates are hinged by a pin shaft, and hinge points between the pin shaft and the hook plates are positioned on the upper sides of the hook heads. The special sling is characterized by being further provided with an anti-unhooking device which comprises a clamping plate, wherein a bayonet is formed in one end of the clamping plate, the other end of the clamping plate is hinged to one hook head, and a limiting pin, which corresponds to the bayonet, is arranged on the other hook head. The special sling for hoisting the steel rail has the advantages of simple structure and easiness in manufacturing, and the anti-unhooking device is arranged, so that the steel rail is unlikely to unhook when being hoisted, the construction operation schedule is prevented from being influenced, the steel rail is prevented from being damaged, and the reliability and the safety are improved.

Description

Rail special hanger for hoisting
Technical field
The present invention relates to a kind of suspender, be specifically related to a kind of rail special hanger for hoisting.
Background technology
Rail, in lifting process of deployment, due to the profile of track, often adopts steel rope binding lifting operation while lifting in the past, but rail basis, Yu Lianghuo ground, ground contact when laying causes rail rear steel rope in place to take out difficulty, affects construction operation efficiency.Chinese patent CN203199883U, discloses the scissors-type suspender that a kind of rail lifts use, simple to operate during use, can fast hoisting, rail is installed, its clamp angle is adjustable, can adapt to the lifting of dissimilar rail, and utilize firmly fixing rail of scissors principle clamp, guaranteed application safety.But the gib head of this suspender can free-open-close, when lifting rail, be easy to break off relations, can have influence on construction operation progress, cause the damage of rail, but also can produce certain potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in structure, rail special hanger for hoisting that can anti-locking hook.
For solving the problems of the technologies described above, the invention provides a kind of rail special hanger for hoisting, comprise two hook plates that are symmetrical set, the upper end of hook plate is provided with lifting hole(eyelet), lower end is provided with the gib head that can clamp rail, between two hook plates, by bearing pin, be hinged, hinge-point between bearing pin and hook plate is positioned at gib head upside, its difference is: be also provided with Anti-hook releasing device, Anti-hook releasing device comprises clamp, one end of clamp arranges bayonet socket, and the other end is articulated with on a gib head wherein, and another piece gib head is provided with the locating dowel pin corresponding with bayonet socket.
Preferably, during described clamp horizontal positioned, the opening of bayonet socket should be down, so that clamp is closely fastened on locating dowel pin.
Conventional, described hook plate and gib head are all integrated, and its width is preferably 20~30mm, and thickness is preferably 12~15mm.
The invention has the beneficial effects as follows: this rail special hanger for hoisting is simple in structure, easily manufacture, by Anti-hook releasing device is set, during lifting, rail is difficult for breaking off relations, and has avoided construction operation progress to be affected and has been damaged with rail, has improved reliability and safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of the present invention.
Number in the figure: 1, lifting hole(eyelet); 2, hook plate; 3, bearing pin; 4, clamp; 5, locating dowel pin; 6, gib head; 7, rail.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
As shown in Figure 1, the rail special hanger for hoisting of the present embodiment comprises two hook plates that are symmetrical set 2, and the upper end of hook plate 2 is provided with lifting hole(eyelet) 1, and lower end is provided with the gib head 6 that can clamp rail, between two hook plates 2, by bearing pin 3, be hinged, the hinge-point between bearing pin 3 and hook plate 2 is positioned at gib head 6 upsides; This rail special hanger for hoisting is also provided with Anti-hook releasing device, Anti-hook releasing device comprises clamp 4, one end of clamp 4 arranges bayonet socket, the opening of bayonet socket when clamp 4 horizontal positioned down, the other end of clamp 4 is articulated with on a gib head 6 wherein, and another piece gib head 6 is provided with the locating dowel pin corresponding with bayonet socket 5.Hook plate 2 and gib head 6 are one-body molded, for example, can be made by the cutting of same steel plate, and the thickness of steel plate used is 12~15mm, and after cutting, hook plate 2 and gib head 6 width of gained are 20~30mm.
During use, before lifting, first with steel wire penetrating lifting hole(eyelet) 1, be connected, then rail 7 terminations, top are blocked with gib head 6, and the bayonet socket of clamp 4 is clamped on locating dowel pin 5, the position of adjusting rail special hanger for hoisting makes rail 7 liftings steadily, after rail 7 is in place, clamp 4 is pushed aside, proceed the lifting operation of other rail 7, until install, finish.
