Abstract
The utility model discloses an anti-tilting device of an H-shaped steel bracket of a mine roadway, belonging to the support of the H-shaped steel bracket of the roadway and comprising a connecting rod, two screws with opposite screw rotating direction and a clamp for clamping the H-shaped steel bracket, wherein the connecting rod is a double connecting rod with the two ends being integrated into a whole body; the two ends of the connecting rod are provided with symmetrical thread holes; one end of each screw rod is screwed into the threaded hole of each end of the connecting rod, and the other end thereof supports against the H-shaped steel bracket needing to be supported; the two screw rods are respectively provided with adjusting nuts capable of rotating on the screws; and the adjusting nuts are hard-connected with the clamp. Since the technical scheme is adopted, i.e., a movable connection mode is adopted, the anti-tilting device expands the usable range, can be adjusted with the distance of two supporting sheds, is also applicable to tilting prevention and firmness of a plurality of groups of supporting sheds, and can be used repeatedly and alternatively.
Description
Technical field
The utility model relates to roadway i iron bracket support, specifically is a kind of mine laneway i iron support tilting prevention device.
Background technology
Mine laneway supporting, i iron support are modal a kind of support forms.Regulation according to " safety regulations in coal mine " the 41 first item:, before explosion, must reinforce near the supporting in the driving face 10m.But in practice of construction, the measure of employing implements cumbersome, time-consuming, effort; Tie up binding such as the employing pipe, the track that have; (bad) support that collapses is easily blown out in the simple binding that has, but firmly degree is not enough, does not reach anti-down consolidation effect, so the anti-down reinforcing of support is puzzlement constructor's a difficult problem always, has both influenced construction speed, is unfavorable for safety in production again.
Summary of the invention
For addressing the above problem, the utility model provides a kind of mine laneway i iron support tilting prevention device, be used for the supporting of mine underworkings driving face i iron supporting canopy, especially in the explosion digging laneway and in the construction of going down the hill, use, can prevent effectively that support from being collapsed.
The utility model is realized with following technical scheme: a kind of mine laneway i iron support tilting prevention device, it is characterized in that: comprise the screw rod that connecting rod, two screw thread rotation directions are opposite and the anchor clamps of clamping I-shaped steel bracket, described connecting rod is the double link that two ends link into an integrated entity, be provided with the screwed hole of symmetry at the two ends of connecting rod, one end of two screw rods is screwed into from the screwed hole at connecting rod two ends respectively, and the other end withstands on respectively on the i iron support that needs to support; On two screw rods, respectively be equipped with can turn on screw rod adjusting nut, adjusting nut is connected firmly with anchor clamps.
Owing to adopted technique scheme, promptly adopted the mode that flexibly connects, enlarged the scope of application, regulate with the distance of two supporting canopies, be applicable to the anti-down fastening of many group supporting canopies again, and can repeat, be used alternatingly.
The beneficial effects of the utility model are: simple and reasonable, volume is little, and is in light weight, is convenient to install, and dismounting speed is fast, convenient moving.More convenient to operate simple, it is time saving and energy saving, safe and reliable to regulate, and especially uses in the explosion digging laneway and in the construction of going down the hill, and can prevent effectively that support from being collapsed.Thereby be easy to promote, have good society and economic benefit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the schematic diagram of the utility model mine laneway i iron support tilting prevention device
Among the figure: 1, connecting rod, 2, screw rod, 3, screw head, 4, anchor clamps, 5, adjusting nut, 6, connect pin, 7, the i iron support.
The specific embodiment
As accompanying drawing institute, mine laneway i iron support tilting prevention device has a connecting rod 1, two screw rods 2 and is positioned at the anchor clamps 4 of the clamping I-shaped steel bracket in two screw rod 2 outsides, two screw rod 2 screw thread rotation directions are opposite, so that pivot link 1 can be regulated two screw rods 2 simultaneously.Connecting rod 1 is the double link that two ends link into an integrated entity, be provided with the screwed hole of symmetry at the both ends of connecting rod 1, one end of two screw rods 2 is screwed into from the screwed hole at connecting rod 1 two ends respectively, the other end withstands on respectively on the i iron support 7 that needs to support, be to increase the contact area of screw rod and i iron, respectively be provided with a flat head screw head 3 at the other end of two screw rods 2.On two screw rods 2, also respectively be equipped with can turn on screw rod adjusting nut 5, on anchor clamps 4 and adjusting nut 5, have pin-and-hole, with connecting pin 6 adjusting nut 5 and anchor clamps 4 are linked together.The degree of depth of anchor clamps 4 generally is not less than 30mm, and when preventing from canopy constructed, i iron interlaces, and anchor clamps can't clip two i iron.
Concrete using method is: pivot link 1, utilize two screw rods, 2 screw thread opposite configuration, and the distance that can regulate 3 on two screw rods head tightly withstands on an end of the band screw head 3 of two screw rods 2 of reversion prevention apparatus on the anchor clamps 4, guarantees two screw rods head stretching support.When going down the hill to construct, rotate adjusting nut 5 or rotating screw bolt 2, make anchor clamps 4 chucking i iron supports 7, prevent that the i iron support from skewing, collapsing, accomplish to support the jail tension conscientiously and really play reinforcement effect.Gallery or only go up a hill when needing stretching can take out connecting pin 6 anchor clamps 4 are unloaded, further weight reduction.
Claims (3)
