Description
Technical Field
The utility model relates to an earth pressure balance shield constructs quick-witted tunnel electric locomotive horizontal transport field, concretely relates to prevent track jump sleeper.
Background
In a shield construction site, a storage battery car is used for horizontal transportation, the track laying requirement is improved along with tunnel excavation, one-time channel skipping can cause delay of a long time period, and serious people can cause accidents. In the running process of the battery car in the tunnel, the main reasons of track distance mismatching, track connection infirm, pull rod looseness, equipment self and the like of the jumping track are caused. The most common mismatching of the gauge is adopted, when most of the conventional tracks are installed, the pressure plate and the bolts are used for fixing, and after the vehicle runs for a long time, the sizes of the bolt installation holes are changed or the bolts are loosened to cause the looseness of the tracks.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the unmatched problem of storage battery car gauge in tunnel operation process, providing a prevent jumping the track pillow, simple to operate, the gauge error that causes when having avoided the installation.
The utility model provides an anti-jumping rail pillow, it includes the arc steel sheet that encircles down, be equipped with two track supporting platform down on the arc steel sheet that encircles, and two track supporting platform set up the both sides of the arc steel sheet that encircles under symmetrically, all are equipped with track fixed knot on each track supporting platform and construct, and aforementioned track fixed knot constructs including trapezoidal briquetting and semi-circular briquetting, and the mounting rail in aforementioned trapezoidal briquetting and the semi-circular briquetting is pressed admittedly orbital edge.
Furthermore, the radian of the lower arched steel plate is matched with that of the circular tunnel constructed by the shield tunneling machine.
Furthermore, the trapezoid pressing block is an inverted right trapezoid, the inclined edge of the right trapezoid presses against the inclined surface on one side of the rail base, and the semicircular pressing block presses against the other side of the rail base to be fixed.
Further, the rail supporting platform adopts an I-shaped steel cutting piece.
Furthermore, the bevel edge of the trapezoidal pressing block is provided with an anti-skid rubber veneer.
Furthermore, the contact surface of the semicircular pressing block and the rail is provided with a convex edge.
The utility model has the advantages of it is following:
the utility model discloses a sleeper includes arched steel plate down, two track supporting platform of welding on the arched steel plate down, and the last welded rail fixed knot of track supporting platform constructs, and each part size is fixed, simple to operate, the gauge error that causes when having avoided the installation.
The utility model discloses a track fixed knot that trapezoidal briquetting and semi-circular briquetting constitute constructs, and it is solid to orbital edge pressure, and it is not hard up to have avoided the not hard up track that leads to of operation in-process bolt, has improved factor of safety and production efficiency, and manpower, material resources that avoid long-term adjustment track to cause are extravagant.
Drawings
Fig. 1 is the overall structure schematic diagram of the anti-track-jumping sleeper of the present invention.
Detailed Description
Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present invention have been illustrated in the accompanying drawings, it is to be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
As shown in figure 1, the anti-jumping sleeper comprises a lower arched steel plate 5, wherein two track supporting platforms 4 are arranged on the lower arched steel plate 5, the two track supporting platforms 4 are symmetrically arranged on two sides of the lower arched steel plate 5, a track fixing structure is arranged on each track supporting platform 4, the track fixing structure comprises a trapezoidal pressing block 2 and a semicircular pressing block 3, a track 1 is arranged in the trapezoidal pressing block 2 and the semicircular pressing block 3, and the edge of the track 1 is pressed and fixed.
In the embodiment, the track supporting platform 4 is made of an I-steel cutting piece, the I-steel cutting piece is formed by cutting I250mm I-steel, the track supporting platform 4 is welded on two sides of the lower arched steel plate 5, and on each track supporting platform 4, the trapezoidal pressing block 2 and the semicircular pressing block 3 are symmetrically welded to clamp and press the edge of the track 1.
Further, the radian of the lower arched steel plate 5 is matched with that of the circular tunnel constructed by the shield tunneling machine.
In this embodiment, after the shield machine is constructed, the ground surface after the tunnel excavation is the arc surface formed by the shield machine, and the radian of the lower arched steel plate 5 is matched with the excavation surface.
Furthermore, the trapezoid pressing block 2 is an inverted right trapezoid, the inclined side of the right trapezoid presses against the inclined plane on one side of the base of the track 1, and the semicircular pressing block 3 abuts against the other side of the base of the track 1 to be fixed.
In the present embodiment, both the trapezoidal compact 2 and the semicircular compact 3 are welded pieces.
Furthermore, the bevel edge of the trapezoidal pressing block 2 is provided with an anti-skid rubber veneer; the contact surface of the semicircular pressing block 3 and the track 1 is provided with a convex edge.
In the embodiment, the antiskid rubber veneers on the inclined sides of the trapezoidal pressing blocks 2 are pressed on the inclined surface on one side of the base of the track 1 for antiskid fixation; convex edges on the semicircular pressing block 3 are in contact with the track 1, so that the friction force and the stability are increased.
The utility model discloses a theory of operation and use flow:
when the storage battery car track is installed, the track is laterally installed to the lower end of the trapezoidal pressing block and then further pressed down until the track is laid flat, firm and reliable.
While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
