Abstract
The utility model discloses transport trolley stop device in a kind of heavy grade shield tunnel, relate to shield tunnel construction technology field.The utility model comprises symmetry and is arranged on a pair backstop apparatus in section parallel steel rails at the bottom of heavy grade slope, and described backstop apparatus is door font, and the lower end of backstop apparatus is installed with pipe link.The utility model can be avoided, because slipping the collision case that the reasons such as car, brake failure or human negligence cause, reducing potential safety hazard, avoiding personal casualty and device damage.
Description
Technical field
The utility model relates to shield tunnel construction technology field, particularly transport trolley stop device in a kind of heavy grade shield tunnel.
Background technology
In recent years, along with the development increasingly in city, the traffic jam in city becomes the obstacle hindering urban development day by day, and for alleviating traffic jam and pulling economic development, China's metro construction is flourish.In subway work, shield method is because its speed of application is fast, safety is high and be used widely to the feature such as bottom disturbance is little.
In tunnel, the operation of transport trolley horizontal transport is the important component part of shield-tunneling construction works, carries the important task of shield duct piece, mud, operating personnel and construction material goods and materials continuative transport.Tunnel transport is safely and efficiently the important guarantee that subway shield tunnel construction carries out smoothly.But passing through some special geology landform, be subject to the constraint of the condition such as existing preheating embedding line and external environment restriction, tunnel line must be designed to heavy grade.The transportation route of heavy grade, when transport trolley uphill, downhill is transported, exist and slip the hidden danger such as car, brake failure, serious meeting causes huge accident, and serious threat is to the safety of life and property of workmen.
Utility model content
Technical problem to be solved in the utility model is to provide transport trolley stop device in a kind of heavy grade shield tunnel, can avoid because slipping the collision case that the reasons such as car, brake failure or human negligence cause, reduce potential safety hazard, avoid personal casualty and device damage.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: transport trolley stop device in a kind of heavy grade shield tunnel, comprise symmetry and be arranged on a pair backstop apparatus in section parallel steel rails at the bottom of heavy grade slope, described backstop apparatus is door font, and the lower end of backstop apparatus is installed with pipe link.
Further, described backstop apparatus is provided with elastic anti-collision block to the one side of going up a slope.
Further, the door font frame of described backstop apparatus is equipped with elastic anti-collision block.
Further, described elastic anti-collision block is butadiene rubber material.
Further, the horizontal frame of described door font backstop apparatus is spill globoidal structure, corresponding, the elastic anti-collision block be arranged on this horizontal frame is spill globoidal structure.
Further, described pipe link is bolt, through the through hole of backstop apparatus lower end, and fixes with nut.
Further, described pipe link is straight pin, through the through hole of backstop apparatus lower end, and fixes with spring cotter.
The beneficial effect adopting technique scheme to produce is: the utility model adopts the backstop apparatus be arranged on two rails; prevent because slipping the collision case that car, brake failure or maloperation etc. are often sent out or accident may cause; eliminate potential safety hazard potential in work progress; be to one of safety method that construction safety is taked, car body itself, the goods and materials of delivery and other equipment destruction of causing can be avoided to a certain extent and ensure the personal safety of workmen.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is lateral plan of the present utility model;
In figure: 1, backstop apparatus; 2, rail; 3, pipe link; 4, elastic anti-collision block.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The car that slips is that in tunnel, transport trolley is when heavy grade uphill, downhill is run, and the tractive force produced by deadweight is greater than the autonomous downslide occurred when active traction adds friction force.Car accident of slipping can damage and the safety of serious threat workmen the goods and materials of car body itself, delivery and other equipment, causes consequence quite serious.
For prince wife Cao pasture shield tunnel construction, start to be exactly heavy grade curve from starting because prince wife Cao pasture shield structure is interval, transport trolley total length 25 m, storage battery energy is not enough or in Renewal process, there will be headstock tailstock on well head horizontal axis and delays on curve entering hole heavy grade, consider the problem such as brake failure, workmen's carelessness, may there is slipping car, for guaranteeing safety, needing at the bottom of slope, arrange a kind of obstacle, both make locomotive glide, and also can stop the generation of collision case.
Concrete structure of the present utility model comprises a pair backstop apparatus 1, shown in Fig. 1, Fig. 2, for preventing from slipping car or brake failure, symmetry is arranged in the parallel steel rails 2 of section at the bottom of heavy grade slope, and described backstop apparatus 1 is door font, and backstop apparatus 1 is enclosed within rail 2, and with pipe link 3 through rail 2 bottom surface, be fixed on rail 2, when transport trolley slips car or brake failure, the transport trolley of downslide can be blocked.Wherein, when mounted, make the medial surface of backstop apparatus 1 and rail lateral surface 2 closely connected, and fastening with pipe link 3, make backstop apparatus 1 be fixed on rail 2, can not slide; Even if backstop apparatus 1 has loosening in addition, also can block and be blocked by sleeper, not have too large distance of glide; When therefore installing, be close to sleeper as far as possible and be installed as suitable.
The huge impulsive contact force produced when gliding for preventing transport trolley causes damage to the goods and materials of transport or car body itself; elastic anti-collision block 4 is provided with to the one side of going up a slope at backstop apparatus 1; a cushion effect can be produced after the transport trolley glided collides backstop apparatus 1, equipment or goods and materials be played to the effect of protection.
Preferably on the door font frame of described backstop apparatus 1, be equipped with elastic anti-collision block 4, described elastic anti-collision block 4 is butadiene rubber material.
Further, the horizontal frame of described door font backstop apparatus 1 is spill globoidal structure, corresponding, the elastic anti-collision block 4 be arranged on this horizontal frame is spill globoidal structure, can obtain better buffering effect.
As a kind of connection structure, pipe link 3 is bolt, through the through hole of backstop apparatus 1 lower end, and fixes with nut.
As another kind of connection structure, described pipe link 3 can also be straight pin, through the through hole of backstop apparatus 1 lower end, and fixes with spring cotter.
Shield-tunneling construction has a big risk, once there is accident, then can cause serious consequence, therefore must stop various hidden danger, ensures construction safety.The utility model adopts the backstop apparatus be arranged on two rails; prevent because slipping the collision case that car, brake failure or maloperation etc. are often sent out or accident may cause; eliminate potential safety hazard potential in work progress; be to one of safety method that construction safety is taked, car body itself, the goods and materials of delivery and other equipment destruction of causing can be avoided to a certain extent and ensure the personal safety of workmen.
