Description
Technical field
The utility model relates to concreting outfit fields, more specifically say it is a kind of anti-cage and fall structure.
Background technique
Large-scale hydroelectric project concrete pouring construction generallys use the mode of cable machine handling concrete warehousing, and cable machine trolley is logical
It crosses rope traction promotion lower section cage and does horizontal, vertical movement.The reliability of cage and steel wire rope connection structure is to influence to mix
Solidifying soil pours the key factor of safety and efficiency；Traditional cage and steel wire rope connection structure lacks the constraint in horizontal plane, steel
Rotation occurs during handling cage for cord, drives bulb rotation, makes the connection of the bolt of bulb and piston rod, slides
Silk, cage fall that risk is big, and time-consuming for repair and maintenance；Deformation and the mill of wirerope, bulb, bulb cover and piston rod simultaneously
Damage is big, and repair and maintenance is costly；Therefore, cage falls risk height, and time-consuming for repair and maintenance, at high cost.
In the prior art, a kind of " accumulation of energy concrete bucket energy storage oil cylinder piston rod earrings anti-rotational structure " (Shen is disclosed
Please number CN201520341765.1) utility model joined guide plate and guiding axis on the basis of traditional cage, in column
With open long hole on guide plate and guiding axis enabled to limit the displacement of cage with this through long hole.Although this design can also prevent cage
Rotation, but its connecting component is more, and there is also fall off by prolonged use for the structures such as guiding axis itself and retaining ring, connector
Risk.And the protective cover for oil tank of the utility model is equipped with fluting, is convenient for observation structure operating condition, finds and eliminate in time
Security risk guarantees lower section operating personnel and equipment safety.
Summary of the invention
To overcome the above disadvantages, the utility model provides a kind of simple for structure, operates conveniently while can effectively prevent
The only structure that cage is rotated, fallen.
The utility model is achieved through the following technical solutions：
Anti- cage falls structure, including wirerope, protective cover for oil tank, bulb cover, bulb, piston rod, oil cylinder, the steel wire
Rope is connected to bulb cover, and the bulb cover is bolted with bulb, and the bulb is bolted with piston rod, described
Piston rod is connect with oil cylinder, it is characterised in that further includes locking pin, the protective cover for oil tank left and right side is equipped with vertical fluting, institute
It states locking pin and bulb welds and passes through the vertical fluting on protective cover for oil tank；The front of the protective cover for oil tank, in corresponding institute
The position for stating locking pin and the oil cylinder is equipped with rectangular slot, and the bulb cover, locking pin, bulb, piston rod, oil cylinder are respectively positioned on
In protective cover for oil tank.
The utility model has the following advantages that compared with prior art：
1. security performance is excellent：Locking pin is set, prevents the connection bulb rotation of the bolt of bulb and piston rod and falls off, slides
Silk reduces cage and falls risk；Protective cover for oil tank fluting, is convenient for observation structure operating condition, finds and eliminates safe hidden in time
Suffer from, guarantees lower section operating personnel and equipment safety；
2. work efficiency is high：Locking pin is set, improves cage and steel wire rope connection structure stress condition, structure durable can
It leans on, reduces repair and maintenance frequency and difficulty, save the duration；
3. good in economic efficiency：Locking pin limits wirerope and bulb rotation, reduces wirerope, bulb cover, bulb and work
Repair and maintenance expense is saved in the deformation and abrasion of stopper rod.
Detailed description of the invention
Fig. 1 is the utility model positive structure diagram
Fig. 2 is the utility model side structure schematic view
Fig. 3 is the utility model bulb cover, locking pin, bulb and piston rod attachment structure schematic diagram
Respectively marked as 1 wirerope in figure；2 protective cover for oil tank；3 bulb covers；4 locking pins；5 bulbs；6 piston rods；7 oil cylinders；
21 vertical flutings；22 rectangular slots.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and examples, while by illustrating the utility model
Advantage will become clearer and be readily appreciated that.But they do not constitute limitations of the present invention, only for example.
As shown in Figure 1, anti-cage falls structure, including wirerope 1, protective cover for oil tank 2, bulb cover 3, locking pin 4, bulb
5, piston rod 6, oil cylinder 7, the bulb cover 3, locking pin 4, bulb 5, piston rod 6, oil cylinder 7 is respectively positioned on the protective cover for oil tank 2
It is interior；The wirerope 1 is connected to the bulb cover 3；The bulb cover 3 is bolted with the bulb 5；The bulb 5
It is welded and fixed with the locking pin 4；The bulb 5 is bolted with the piston rod 6.The left and right sides of protective cover for oil tank 2
There is vertical fluting 21 in face at correspondence 4 position of locking pin, and the both ends of the locking pin 4 pass through the protective cover for oil tank 2 or so
The vertical fluting 21 of side, locking pin 4 is only capable of moving up and down in perpendicular, can not rotate in the horizontal plane；Such as Fig. 2 institute
Show, there is rectangular slot 22 in the front of the protective cover for oil tank 2 at 4 position of locking pin and 7 position of the oil cylinder, convenient for inspection
It repairs.
In the above-mentioned technical solutions, the bulb 5 is welded on the locking pin 4, is moved up and down simultaneously with locking pin 4,
It can not rotate in the horizontal plane, prevent bulb 5 from connecting the rotation of bulb 5 with the bolt of the piston rod 6 and falling off, stripped thread, drop
Low cage 7 falls risk, and structure durable is reliable.The wirerope in the case where the cage 7 connect the constraint of system with wirerope, by
Power situation is improved, and torsional moment reduces, and deformation and abrasion are reduced, and saves repair and maintenance cost.
In order to clearly illustrate that anti-cage described in the utility model falls structure institute compared with existing structure
It has the advantage that, staff is compared both methods, comparing result such as following table：
As seen from the above table, anti-cage described in the utility model falls structure compared with existing structure, and frequency of maintenance is obvious
Decline, time-consuming significantly reduces, maintenance cost is substantially reduced for maintenance.
Other not specified (NS)s are the prior art.
