On, which has Telescopic, can satisfy diameter 400mm and hole below protection.
Summary of the invention
The technical problem to be solved by the present invention is to can not quickly tear open existing for existing hole protective device to overcome
Unload, install it is random it is larger, can not produce in batches, intensity is difficult to the defect ensured, provide a kind of telescopic hole protection dress
It sets, telescopic hole protective device provided by the invention can be directly installed in Ship Structure by way of collet, and the dress
It sets with Telescopic, intensity is big, can satisfy diameter 400mm and hole below protection.
The present invention is to solve above-mentioned technical problem by following technical solution:
The present invention provides a kind of telescopic hole protective devices, are mounted on the steel plate above hole comprising three
The connection bolt and three fixing bolts of block band steel, three pieces of band steels of connection, the structure of three pieces of band steels is identical, both ends
It is respectively equipped with an adjusting section and a collet, the adjusting section offers a regulating tank, a fixing threaded hole is offered on the collet,
The adjusting Duan Jun of three pieces of band steels extends to the center of described hole, and the connection bolt is successively worn each tune
Slot is saved, for realizing the flexible connection between three pieces of band steels, the collet of three pieces of band steels is set to the steel plate
Top, three fixing bolts wear the fixing threaded hole of three pieces of band steels respectively, for will be described in the band steel
Collet is fixed on the steel plate.
In the present invention, the regulating tank includes groove body, trough and slot tail, and described trough one end is close to the center of described hole
Place, preferably, the trough and the slot tail are identical semicircular structure, the slot is as width and the trough and described
The identical rectangular configuration of slot tail diameter.
In the present invention, position of the connection bolt on the regulating tank is any, according to actual demand, hole area
It is bigger, bolt is connected closer to trough, and hole area is smaller, and connection bolt is closer to slot tail, preferably, the connection bolt is solid
It is in due to the slot close to slot tail one end, so that the pretective acreage of the device of the invention maximizes.
In the present invention, the adjusting section of the band steel is movably connected to form pretective acreage, Yi Mianren by connection bolt
Or object is fallen into hole, preferably, the upper surface of the adjusting section and the upper surface of the steel plate are located in same level.
In the present invention, the collet is used to the band steel being fixed on steel plate by the fixing threaded hole and fixing bolt
On, preferably, the collet is U-shaped structure, the upper surface of described collet layer is located at the upper surface of the steel plate, under the collet
Surface layer is located at the lower surface of the steel plate, so that the bonding strength of the collet and steel plate maximizes.
In the present invention, the fixing bolt is located at the outside of described hole, more with the chance of human contact, preferably,
The top of the fixing bolt is the smooth spheroidal structure in surface, in case people is scraped off after accidentally touching.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can any combination to get each preferable reality of the present invention
Example.
The positive effect of the present invention is that:
1, the present invention is by the way that band steel to be mounted on the steel plate above hole in the form of bolt is fixed, so that hole protects
The dismoutability of device is more preferable, while eliminating disassembly fixed-guard and damaging to steel plate bring.
2, the regulating tank in band steel of the invention can adjust the specific size of protective device according to actual needs, can satisfy
Diameter 400mm and hole below protection, flexibility are high.
Detailed description of the invention
Fig. 1 is a preferred embodiment of the present invention the structural schematic diagram of collapsible protection hole device.
Description of symbols:
Band steel 1；Band steel 2；Band steel 3；
Adjust section 101；Collet 102；
Fixing threaded hole 103；Regulating tank 104；
Connect bolt 4；Hole 5；Steel plate 6.
Specific embodiment
A preferred embodiment is named, and completely illustrates telescopic hole protection of the invention in conjunction with attached drawing to become apparent from
Device.
As shown in Figure 1, a hole 5 is opened up on steel plate 6, it, need to be in hole 5 for carrying out the work such as pressure release, lifesaving or maintenance
