A kind of mould lifting anti-drop device
Technical field
The present invention relates to a kind of mold hoisting assembling structure, more precisely, relate to a kind of anti-drop device of mould lifting.
Background technology
At present, large mold, in order to lift by crane convenient in carrying, generally hangs rod at a bolt-type of the each placement in the hanger place of four jiaos, mould.So that the interspersed lifting rope of site operation personnel, but also easily hang the phenomenon that rod is lost, scene can not find the problem of hanging rod and cannot normally carry out lifting operation while often there is lifting.
Summary of the invention
The present invention hangs rod and in use easily loses this technical matters in order to solve mold pins formula, and a kind of mould lifting anti-drop device is provided.
In order to realize above-mentioned object, technical scheme of the present invention is: a kind of mould lifting anti-drop device, comprise a pair of hanger, described hanger is provided with for interting and hangs excellent hole, describedly hang excellent sidewall and be axially arranged with groove along it, described groove extends to and hangs at least length of half of rod from hanging a termination of rod; On the end face of described hanger, be fixedly mounted with a locking plate, the termination of described locking plate is provided with stretches into groove also and the locking block of groove fit; The described rod that hangs has one in the time extracting, and makes the tail end of groove withstand locking block to prevent the hanging latched position that rod comes off, and one penetrating while hanging excellent hole, the control position that locking block is passed from hanging excellent termination; Describedly hang excellent termination and be also provided with leader.
Preferably, described locking plate is bolted on the end face of hanger.
Preferably, described handle is the rectangle handle that a round steel bending forms.
Preferably, the end face of described hanger is also provided with the limiting stopper of a restriction handle rotational angle.
Preferably, the cross section of described groove takes the shape of the letter U.
Anti-drop device of the present invention, it is simple in structure, and not only overcome traditional bolt-type completely and hung the problem that rod is easily lost, and easy accessibility when having retained traditional bolt-type and hanging rod and intert lifting rope.

Fig. 2 shows and in Fig. 1, hangs the view of rod in the time being inserted into the end.
Fig. 3 shows and in Fig. 2, hangs the structural representation of rod in the time that rotation 90 is spent.
Fig. 4 shows and in Fig. 1, hangs excellent structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
With reference to figure 2, Fig. 4, a kind of mould lifting anti-drop device disclosed by the invention, comprise a pair of hanger 1 being arranged on mould, described hanger 1 is provided with the hole of hanging rod 3 for interting, the described sidewall that hangs rod 3 is axially arranged with groove 30 along it, the cross section of this groove 30 is preferably U-shaped, and described groove 30 extends to and hangs at least length of half of rod from hanging a rod termination of 3; That is, 30 of this grooves have run through the one end of hanging rod 3, and it is mainly determined according to the distance between two hangers 1 in the length of hanging on rod 3.On the end face of described hanger 1, be fixedly mounted with a locking plate 2, the termination of described locking plate 2 is provided with stretches into groove 30 also and the locking block 21 of groove fit.With reference to figure 1, Fig. 3, described in hang rod and 1 there is one in the time extracting, make the tail end of groove 30 withstand locking block 21 to prevent hanging rod 3 latched positions that come off, and one penetrating while hanging excellent hole, the control position that locking block 21 is passed from hanging excellent termination; Described rod 3 the termination of hanging is also provided with leader 31, when locking block 21 is from hanging the termination of rod 3 and passing, rotatably hangs rod 3, and groove 30 and locking block 21 are staggered, and prevents from hanging rod 3 and come off in the time of crane lifting service.
Locking plate 2 of the present invention can be bolted on the end face of hanger 1.The preferred mode of described handle 31 is the rectangle handle that a round steel bending forms.Also be provided with the limiting stopper 11 of restriction handle 31 rotational angles at the end face of described hanger 1.One boss 12 can be set on the end face of hanger 1, and described locking plate 2 is fixed on the end face of this boss 12.
Anti-drop device of the present invention has not only overcome traditional bolt-type completely and has hung the problem that rod is easily lost, and easy accessibility when having retained traditional bolt-type and hanging rod and intert lifting rope.
The present invention is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, the variation to each embodiment and to increase be also that one of ordinary skill in the art institute is apparent.Being intended that all these variations and increasing of applicant all dropped in the scope that the claims in the present invention protect.
