The lower end of an upright post is arranged on a fixing seat, and one side of the upper part of the upright post is connected with the fixing seat through an inclined support. The other side of the upper part of the upright post is connected with a coupler knuckle force bearing plate through a transverse beam arranged on the upright post, and the lower part of the upright post is provided with a box-shaped force bearing device. One end of the fixing seat is connected with a top iron, and the other end is connected with a slide way. The lower end of a sliding seat is arranged on the slide way, and a force transmission rack which is composed of an arc rail clip, a rail clip top iron, an outer side joint plate, an inner side joint plate, the sliding seat and a pressure adjustment screw bolt is arranged on the sliding seat. The inner side and the outer side joint plates are fixed to the sliding seat, one end of a damper spring is connected with a rail clip top plate and the other end is connected with the force bearing device. The vehicle can be effectively prevented from sliding out of the buffer stop.

Description

Buffering fixed type car bumper

The utility model relates to a kind of buffering car bumper that is fixed on line end.

At present, the car bumper that is provided with on the railway line stub end siding is to be used for rolling stock transportation safety equipment.The railway stub end siding is a lot, and its end requires car bumper and marker are set according to " regulations of railway technical operation ", and the car bumper type has by beginning so far: three kinds on navy barrow retaining, barnacle car bumper, cyclopean concrete car bumper are referred to as the gravity type boat davit car bumper.This car bumper does not allow to be higher than 0.6 meter on track, can only the effect of start-stop wheel, yet, when the vehicle of slipping into the circuit end is many, speed is higher, though can first wheel be withstood, but, become the damaged accident of vehicle because the huge force of inertia of vehicle easily breaks vehicle end carriage and central sill; Because the stub end siding end is with a varied topography, have plenty of building constructions such as house owed by a citizen, office building, factory building in the urban district again; Cartridge pin on bogie truck breaks away from, and car body will be gone out car bumper, causes serious consequence.Existing soil retaining is in the majority, account for more than 90%, though this car bumper cost is low, make simple, through for many years wind and weather, poultry pedal, the people steps on the majority state that can not be kept perfectly, and become smooth mound, he very easily goes out car bumper and cause serious accident in case slip into vehicle.

It is a kind of simple in structure, safe and reliable that the purpose of this utility model is to provide, and can actv. prevents that vehicle from going out the buffering fixed type car bumper of the railway line end.

In order to achieve the above object, the utility model adopts a kind of buffering fixed type car bumper, it is to be arranged on the permanent seat at column lower end, column top one side links to each other by diagonal ligament with permanent seat, column top opposite side by be arranged on the column crossbeam with collude tongue load metal plate and link to each other, the column bottom is provided with the boxlike bearing, permanent seat one end and top iron phase connect, the other end links to each other with slideway, the cliding seat lower end is arranged on the slideway, and cliding seat is provided with the force transmission rack that is made of arc rail clip, rail clip top iron, outside yoke plate, inboard yoke plate, cliding seat, pressure adjustable bolt; The medial and lateral yoke plate is fixed on the cliding seat, and recoil spring one end and rail clip top board join, and the other end links to each other with bearing.

Characteristics of the present utility model are:

(1) simple in structure, safe and reliable, the utility model does not need extra power, can automatically reset without manual control, does not need to establish in addition the basis, is directly installed on the rail of line end, becomes the fixed type car bumper in order to substitute existing gravity type boat davit car bumper.

(2) absorption power is bigger, has the buffering crashworthiness, and vehicle and car body are kept off simultaneously, does not damage the effect that vehicle can play the accident of preventing again.

(3) the utility model cost is lower, easily installs, and the signal display apparatus that is provided with on the column can prevent effectively that vehicle from colliding.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, the utility model adopts a kind of buffering fixed type car bumper, it is to be arranged on the permanent seat 2 in column 1 lower end, column 1 top one side links to each other by diagonal ligament 3 with permanent seat 2, column 1 top opposite side by be arranged on the column 1 crossbeam with collude tongue load metal plate 4 and link to each other, column 1 bottom is provided with boxlike bearing 5, permanent seat 2 one ends and top iron 6 join, the other end links to each other with slideway 7, cliding seat 8 lower ends are arranged on the slideway 7, and cliding seat 8 is provided with by arc rail clip 9, rail clip top iron 10, outside yoke plate 11, inboard yoke plate 12, cliding seat 8, the force transmission rack that pressure adjustable bolt 13 constitutes; Medial and lateral yoke plate 12,11 is fixed on the cliding seat 8, and recoil spring 14 1 ends and rail clip top board 15 join, and the other end links to each other with bearing 5.

Described column 1 upper end is provided with signal display apparatus 17.

Described spring, be by every side vertical ground two groups of double coil springs arranged side by side, the forward and backward seat of spring is welded in respectively on the load end plate, it plays energy-absorbing function, can absorb 110 tons of vehicle impulsive contact forces, the permanent seat on the rail, column, diagonal ligament solder together form triangle frame, and it is firm that permanent seat is done the crossbeam connection with two one steel rails, collude tongue retaining by two parallel ground-surface springs and collude tongue load metal plate and forms, the spring back seat is welded on bottom the bracing frame crossbeam.The spring front stall is welded on and colludes on the tongue load metal plate, when colluding tongue, hits when colluding tongue load metal plate by vehicle, vehicle can be blocked, marker is 100 * 48 * 5.3 channel columns, and the bottom is associated on the crossbeam on the column with bolt, top is associated on the signal lamp, the positive 5 millimeters thick glass of installing, the outside scribbles redness, and inner face is the part coating black outside 100 mm dias circle, light source is housed in it, shows between daytime that danger signal light board shows red light night.

Principle of work of the present utility model is:

When 10 above loaded vehicle are no more than 8KM/h speed, when 10 following loaded vehicle are no more than 12KM/h speed and rush at this car bumper, about two wheel cards respectively vehicle two wheel treads are blocked, colluding tongue retaining colludes tongue with vehicle and blocks, the power that acts on the wheel card is passed to energy absorber by force transmission rack, length of spring compressed with energy absorbing.Simultaneously, the permanent seat of the cliding seat dieback bracing frame of force transmission rack acts on excess force on the bracing frame by static(al) kinetic energy is become heat absorption.Act on the power of colluding on the tongue then by colluding tongue load metal plate compression spring with energy absorbing, prevent that vehicle is braked because of wheel, car body is scurried out by inertia.When vehicle is removed, by compressed spring automatically with stressed with collude tongue retaining and return to original position.
