Abstract
The utility model discloses an I beam support collapse preventer, which comprises an I beam -connecting plate (1) and a fixing plate (3); wherein, both sides of a web (6) of the I beam -connecting plate are provided with supporting plates (2); one side of the fixing plate is welded on the web of the I beam -connecting plate; and the fixing plate is provided with two bolt-connecting holes (4) and a long opening (5). The utility model, which has the advantages of simple structure, firm connection and good collapse-preventing effect, can be reused and effectively prevent the collapse and inclination of an I beam shed, preventing accidents.
Description
Technical field
The utility model belongs to the mine support fastening devices, especially relates to a kind of coal mine roadway i iron supporting tilting prevention device.
Background technology
Under the little situation of mine pressure, adopt the i iron supporting under the coal mine usually; especially in tunneling process; it mainly adopts i iron to be built into frame as back timber and support column; frame supports digging laneway at interval one by one; driving face is played a protective role, but the shaking force that produces in tunneling process, sudden roof pressure and big gun digging impact force when advancing the work plane explosion etc. all can cause down the generation of canopy and roof fall accident.Be head it off, the anti-down protective device of the relevant frame that adopts is a lot of at present, and some adopts bolt to compress mode and the folding wedge mode is fixed frame, but complex structure, complex operation is difficult for complex manufacturing technology is installed; Some tilting prevention device be with two catch jackets on i iron, by regulating the flexible screw thread between two claws, frictionally is bearing between two i iron, but exists defective not firm as connecting, anti-down weak effect is time-consuming and shortened application life of tilting prevention device.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model provides a kind of effective i iron supporting tilting prevention device simple in structure, easy to use, easy to assemble, anti-down.
For achieving the above object, the utility model adopts following technical scheme:
Described i iron supporting tilting prevention device, it is made up of i iron junction plate and fixed head, the web both sides of i iron junction plate are equipped with gripper shoe, the web of fixed head one side and i iron junction plate is integrally welded, fixed head is provided with two bolt connecting holes, also is provided with a long opening on the fixed head.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This i iron supporting tilting prevention device, simple in structure, volume is little, in light weight, is connected firmly, easy to assemble, anti-down effective, and reusable, can the back timber and the support column of i iron supporting is fixing simultaneously, and many canopies can be connected as a single entity, strengthen anti-down effect, effectively avoid the i iron frame to be collapsed, collapse askew, the accident that prevents takes place.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 is a scheme of installation of the present utility model;
Among the figure: 1-i iron junction plate; The 2-gripper shoe; The 3-fixed head; The 4-bolt connecting hole; The long opening of 5-; The 6-web; The 7-back timber; The 8-support column; The 9-clamping plate.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, 2: the utility model i iron supporting tilting prevention device, it is made up of i iron junction plate 1 and fixed head 3, web 6 both sides of i iron junction plate 1 are equipped with gripper shoe 2, the web 6 of fixed head 3 one sides and i iron junction plate 1 is integrally welded, fixed head 3 is provided with two bolt connecting holes 4, also is provided with a long opening 5 on the fixed head 3.
Supporting is built into trapezoidal frame by i iron as back timber 7 and support column 8, is provided with the block that can prevent that support column from tilting in the tunnel at the two ends of back timber (portion), and support column 8 has square clamping plate 9 with back timber 7 junctions.During use, 4 tilting prevention devices are installed altogether on each i iron frame, a tilting prevention device is respectively installed in the front and back of back timber and support column connecting portion; Installation process as shown in Figure 3, the upper end of i iron junction plate 1 is stuck on the bottom flange of h beam cap 7 of frame, clamping plate 9 belows that gripper shoe 2 is inserted on the i iron support column 8, with two connecting bolts the tilting prevention device before and after the back timber is connected and fixed, just that the back timber and the support column of i iron supporting is fixing simultaneously, pass long opening 5 on the fixed head with the connection leading screw, adjacent frame can be linked together; Many canopies can be connected as a single entity with same operation.
