Description

Special lifting appliance for die holder

Technical Field

The utility model relates to a hoist, especially a mould die holder special lifting device.

Background

At present, most of dies (or die holders) are only provided with lifting holes on two side walls and are not provided with lifting lugs. And the most common present spreaders are hook spreaders. The lifting state of the mould (or the die holder) by using the hook type lifting appliance is shown in figure 3. The lifting hook type lifting appliance comprises a chain, rings and hooks 8, wherein the rings and the hooks are connected to two ends of the chain, when a mould (or a mould base) needs to be lifted, a lifting rod 7 needs to be inserted into a lifting hole in the side wall of the mould (or the mould base) firstly, then the rings are connected to lifting hooks of a travelling crane, the hooks 8 are hung on the lifting rod 7, and finally the travelling crane is operated to lift.

The hoisting step is relatively complicated to operate, and the risk that the hook slides off the hoisting rod exists in the hoisting process, so that the method is very unsafe.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, and provide a mould die holder special lifting device, complex operation when it has solved current hook formula hoist and has lifted by crane mould (or die holder), has the problem of safe risk.

The technical scheme of the utility model is that: the special lifting appliance for the die holder comprises a main lifting ring, a branch lifting ring, an upper safety ring, a chain, a lower safety ring and a lifting assembly which are sequentially connected from top to bottom.

The utility model discloses further technical scheme is: the hoisting assembly comprises a shaft sleeve, a hoisting rod and an outer ring; the shaft sleeve is movably sleeved outside the lifting rod and is positioned in the axial direction, the outer ring is welded outside the shaft sleeve, and a ring penetrating hole is formed between the outer ring and the outer wall of the shaft sleeve.

The utility model discloses further technical scheme is: the upper safety ring comprises a rotating shaft A and two C-shaped pieces A movably connected to the rotating shaft A; an upper connecting hole A and a lower connecting hole A are formed between the two C-shaped pieces A and the rotating shaft A respectively; the lower safety ring comprises a rotating shaft B and two C-shaped pieces B movably connected to the rotating shaft B; an upper connecting hole B and a lower connecting hole B are formed between the two C-shaped pieces B and the rotating shaft B respectively; the branch rings are connected into an upper connecting hole A of the upper safety ring, the upper end of the chain is connected into a lower connecting hole A of the upper safety ring, the lower end of the chain is connected into an upper connecting hole B of the lower safety ring, and the outer ring is connected into a lower connecting hole B of the lower safety ring through a ring penetrating hole.

Compared with the prior art, the utility model have following advantage:

the utility model is suitable for a lifting by crane of mould (or die holder) that has the jack-up hole, simple structure is reasonable, easy and simple to handle, and the security is compared current lifting hook formula and is hung and have promoted.

The invention is further described below with reference to the figures and examples.

Detailed Description

Example 1:

as shown in fig. 1, the special lifting device for the die holder comprises a main lifting ring 1, a sub lifting ring 2, an upper safety ring 3, a chain 4, a lower safety ring 5 and a lifting assembly which are sequentially connected from top to bottom. The lifting assembly comprises a sleeve 61, a lifting rod 62 and an outer ring 63. The shaft sleeve 61 is movably sleeved outside the lifting rod 62 and is positioned in the axial direction, the outer ring 63 is welded outside the shaft sleeve 61, and a ring penetrating hole is formed between the outer ring and the outer wall of the shaft sleeve 61. The upper safety ring 3 comprises a rotating shaft A31 and two C-shaped pieces A32 movably connected to the rotating shaft A31. An upper connecting hole A and a lower connecting hole A are respectively formed between the two C-shaped pieces A32 and the rotating shaft A31. The lower safety ring 5 comprises a rotating shaft B52 and two C-shaped pieces B52 movably connected to the rotating shaft B52. An upper connecting hole B and a lower connecting hole B are respectively formed between the two C-shaped pieces B52 and the rotating shaft B51. The sub-lifting ring 2 is connected in an upper connecting hole A of the upper safety ring 3, the upper end of the chain 4 is connected in a lower connecting hole A of the upper safety ring 3, the lower end of the chain 4 is connected in an upper connecting hole B of the lower safety ring 5, and the outer ring 63 is connected in a lower connecting hole B of the lower safety ring 5 through a ring penetrating hole.

Preferably, the number of the sub-lifting rings 2 is two, each sub-lifting ring 2 is connected with two upper safety rings 3, and correspondingly, each upper safety ring 3 is sequentially connected with a chain 4, a lower safety ring 5 and a group of hoisting assemblies.

Brief description the utility model discloses a use: when the die (or the die holder) needs to be lifted, the main hoisting ring 1 is connected to a hoisting hook of the traveling crane, the hoisting rod 62 is inserted into a hoisting hole of the die (or the die holder), and finally the traveling crane is operated to hoist.
