Description
Technical field
The utility model belongs to technical field of building construction, and in particular to a kind of rail limiting device.
Background technology
With the fast development of mountainous area highway, railway, the scale of mountain tunnel is also growing, to solve tunnel of growing up
The operation ventilation problem in road, major long tunnel are both provided with ventilation inclined shaft.Inclined shaft, all has certain longitudinal slope gradient, and inclined shaft two serves as a contrast
Construction is typically chosen integrated liquid hydraulic trolley, and integral hydraulic trolley traveling system track is rail, trolley entire length length, ton
Position greatly, is fixed on after trolley positioning on rail, and easily generation nature is slippery or because of delivery pump construction pump line impact force, lower section passage vehicle
Collision trolley occurs slippery, jeopardizes human life and the Construction traffic of trolley downstream direction, to cause extremely serious peace
Full accident.
Invention content
The utility model be easy to happen in the construction process for trolley it is slippery and the problem of cause safety accident, provide one
Kind rail limiting device.
One end of a kind of rail limiting device, including one group of intermediate plate, gad and fixed plate, intermediate plate is equipped with clamping block, another
End has been equipped with the pin hole of connection function, and the centre of intermediate plate is equipped with the bolt hole to play the role of fastening, and the clamping block of intermediate plate is along track
It is arranged symmetrically, the sharp vertebra end of gad is located at the bolt in bolt hole and between track end face, fixed plate is located at the two of track
The top of side, fixed plate is equipped with to fagging, is connect respectively with fixed plate to the both ends of fagging, the upper end of gad is located to fagging,
Fixed plate bottom is beyond track end face and coats gad.
The center at the center of the clamping block, the center of pin hole and bolt hole is located at same vertical line.
The taper of the tip cone end of the gad is 15-30 °.
Length of the fixed plate bottom beyond track end face is 10-15cm.
The fixed plate is equipped with the fastener hole to play the role of fastening.
The beneficial effects of the utility model are as follows：
The utility model is simple in structure, easy to make, and consumptive material is few, is fixed by clamping block and track anchor ear, intermediate plate outsourcing
Plate securing device achievees the effect that effectively to limit trolley, can be effectively prevented the lining trolley of major long tunnel inclined shaft two and easily slip
The generation of sliding hidden danger, greatly improves the safety of the lining construction of inclined shaft two, while ensure that two lining trolley downstream Construction traffics
And the safety of pedestrian has saved labour cost moreover, saving labour, improves work efficiency.Therefore, the construction tool
It is cost-effective, tunnel construction technology is greatly enriched, there is extremely extensive promotional value.

Specific implementation mode
In conjunction with attached drawing, the utility model is described further.
One end of a kind of rail limiting device, including one group of intermediate plate 1, gad 2 and fixed plate 3, intermediate plate 1 is equipped with clamping block 4,
The other end has been equipped with the pin hole 5 of connection function, and the centre of intermediate plate 1 is equipped with the bolt hole 6 to play the role of fastening, the clamping block 4 of intermediate plate 1
It is arranged symmetrically along track 7, the sharp vertebra end of gad 2 is located between 7 end face of the bolt in bolt hole 6 and track, and fixed plate 3 is distinguished
Positioned at the both sides of track 7, the top of fixed plate 3 is equipped with to fagging 8, is connect respectively with fixed plate 3 to the both ends of fagging 8, to support
Plate 8 is located at the upper end of gad 2, and 3 bottom of fixed plate is beyond 7 end face of track and coats gad 2.
The center at the center of the clamping block 4, the center of pin hole 5 and bolt hole 6 is located at same vertical line.
The taper of the tip cone end of the gad 2 is 15-30 °.
Length of 3 bottom of the fixed plate beyond 7 end face of track is 10-15cm.
The fixed plate 3 is equipped with the fastener hole 9 to play the role of fastening.
The operation principle of the utility model is as follows：Intermediate plate 1 is made using the steel plate of 30mm, the pin hole 5 of intermediate plate 1 passes through steel
Pin is hingeably secured on two lining trolley traveling device ends, and after trolley is in place, high-strength bolt is installed on middle part bolt hole 6,
So that the 4 secured anchor ear of clamping block of 1 other end of intermediate plate is between 7 both sides of trolley track, the middle part bolt and top of the rail of intermediate plate 1
Gap section gad 2 stopper, to ensure the stabilization of gad 2, gad 2 is wrapped in the outside of gad 2 setting fixed plate 3,
Fixed plate 3, to drawing, ensures the problems such as skew back, sliding do not occur for gad 2, to finally ensure that the covering device can with high-strength bolt
Effective limit to two lining trolleys.
Before mobile two linings trolley, the high-strength bolt of fixed plate 3, intermediate plate 1 is unclamped successively and opens fixed plate 3, forward
It is mobile trolley used, after trolley is in place, then passes sequentially through high-strength bolt and fix intermediate plate 1（Including installing gad）, installation consolidate steel plate
3, ensure effective limit of trolley.Often locate limiting device, only a people is needed to can be completed, it is easy to operate, quick.
