Abstract
The utility model relates to a wheel stopper belonging to a brake with the mutual effect of braking elements and railways. A wedge-shaped block is formed by the weld of steel plates, and the wedge angle of two wedge-shaped blocks are symmetrically placed towards two outer sides. Two wedge-shaped blocks are respectively provided with a hole on the vertical plane corresponding to a wedge angle, and the two holes have the same shaft line. Both sides are provided with a screw rod with two nut screws, and both ends thereof are respectively inserted in a hole which is arranged on the vertical plane of the two wedge-shaped blocks. The wheel stopper can complete the bidirectional fixation and have the advantages of simple structure, convenient use, high operational reliability, and good external force resistance ability; the vehicle can not move, and no gap remains the wedge-shaped block and the wheel after the wheel stopper is properly arranged.
Description
The utility model relates to a kind of wheel skid, belongs to the interactional drg of braking element and railway.
According to safety procedure regulation, being operated in locomotives such as all kinds of unloaders on the open-air track, hoisting crane, transport trolley, anchoring devices such as stirrup strap, top rail machine all should be set also is wheel skid, with windproof anti-creep, avoids not firm because of fixing, and leads to a disaster.Chinese patent ZL97212698.8 discloses a kind of " rail formula hoisting crane band pawl wind resistance skate ", form by top board, bolt, jacking block, pawl and base plate etc., base plate and the top board on it constitute wedge, and four pawls that are installed in the font breach of base plate both sides " T " are fixed this skate in orbit with jacking block, bolt combined action.Its existing problem is: complex structure, use inconvenience; Each skate can only unidirectionally be fixed, and it is two-way fixing to use two skates just can finish, and installs, the dismantlement work amount is big; There is the gap in the installation of each skate inevitably by artificial placement and fixing between wheel and the wedge, easily produce under external force and move, and influences fixing safe effect.
The purpose of this utility model provide a kind of simple in structure, easy to use, functional reliability is high, opposing external force ability strong wheel skid, to improve the operational security of all kinds of locomotives of working on the track in the open.
The purpose of this utility model realizes by following measure.
A kind of wheel skid, wedge is made by the steel plate welding, and the angle of wedge of two wedges is placed to two outsides symmetry respectively.Two wedges with angle of wedge opposing vertical plane on respectively offer a hole, two hole coaxial lines.Both sides are equipped with its two ends of screw rod of two nuts and insert respectively in the hole of offering on two wedge vertical plane surfacies.Locking angle on the wedge=10～20 °.
The advantage that the utility model is compared with prior art had is: simple in structure, a wheel skid can be finished two-way fixing, and need not be fixed on track or the car body, and is easy to use, quick.Fixedly support realization by the two-way top of revolving, just can not leave the gap in case be in place between wedge and the wheel, make locomotive not have any mobile leeway, functional reliability height, opposing external force ability is strong, significantly improved the operational security of all kinds of locomotives of working on the track in the open.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of the utility model wheel skid.
The utility model wheel skid as shown in the figure, is made up of wedge 1, nut 2 and screw rod 3.Wedge 1 is made by steel plate welding, locking angle=15 °, because its inside is hollow, so weight is lighter.The angle of wedge of two wedges 1 is placed to two outsides symmetries respectively, two wedges 1 with the corresponding vertical plane surface 1a of the angle of wedge, also be respectively to offer a hole on the usually said back facade, two holes are positioned on the same axis.Both sides are equipped with screw rod 3 its two ends of two nuts 2 and insert respectively in the hole of offering on two wedges, the 1 vertical plane surface 1a, and nut 2 is close to the vertical plane surface 1a of two wedges 1.Screw rod 3 should have cooresponding intensity, and its diameter generally is not less than 20mm.
During work, select the length of the screw rod 3 of wheel skid according to the wheelspan of locomotive.Two wedges 1 are positioned on two tracks that face mutually between the wheel, rotating two nuts, 2 promotions, two wedges 1 enters between the wheel and track of both sides its angle of wedge respectively, utilize the antagonistic force between nut 2 and the screw rod 3, two wedges 1 hold out against the wheel on both sides.Produce huge friction force between wedge 1 bottom surface and the track this moment, stops the displacement of wheel, and wheel is firmly locked.
Claims (2)
1. wheel skid, has wedge, it is characterized in that: wedge (1) is made by the steel plate welding, the angle of wedge of two wedges (1) is placed to two outsides symmetry respectively, two wedges (1) with angle of wedge opposing vertical plane (1a) on respectively offer a hole, two hole coaxial lines, both sides are equipped with its two ends of screw rod (3) of two nuts (2) and insert respectively in the hole of offering on two wedges (1) vertical plane surfacies (1a).
2. wheel skid according to claim 1 is characterized in that: locking angle=10～20 on the described wedge (1) °.
