Abstract

The utility model relates to an emergency brake device added on a vehicle. A slide plate is connected with a falling compressed spring arranged on a vehicle frame and can slides in a slide groove body. The end of the slide plate is hinged with a triangular wedge at the front of the vehicle. The falling pressure spring is connected with a return pressure spring in a spring box through a pulling rod. The triangular wedge is inserted with a road surface protective plate made of rubber. Thus, the utility model has the advantages that the braking action is quick, and the road surface can not be damaged.

Description

Emergency brake device

The utility model relates to a kind of emergency brake arrangement that is attached on the self-propelled vehicle, but mainly by be arranged on triangle drift before the wheel, fixedly be subjected on the vehicle frame button switch control in the operator's compartment electromagnet, linked up with by the control of magnet control and hook triangle drift, be arranged on hand ratchet on the vehicle frame and the end steel rope that the other end on the hand ratchet has a hook hand of reeling and form, belong to the braking technology in the communications and transportation.

At present, be attached to the brake gear on the self-propelled vehicle, its keystone configuration is to hang the triangle drift in wheel the place ahead, in emergency circumstances need when brake moment meeting, handle operator's compartment internal control button switch, make the triangle drift fall to the road surface, the wheel pad of advancing from the road surface, and is produced huge friction force by triangle drift and ground and reaches the purpose that moment brakes.But it exists because of the triangle drift directly contacts the ground-surface problem of damaging with the road surface when brake, and the triangle drift needs the regular hour by time on the deadweight road surface, whereabouts simultaneously, thereby also exists long weak point of brake time.

The purpose of this utility model is exactly at damaging ground-surface problem and long weak point of brake time during brake in above-mentioned, and can shorten the emergency brake arrangement of time on the road surface, triangle drift whereabouts not only can not damage road surface but also brake when a kind of the brake is provided the time.

Task of the present utility model realizes by following technical measures: fix a slide plate cell body on the vehicle frame on every side mudguard, hinged and the interior stage clip end, whereabouts of the other end and the slide plate cell body bonded assembly slide plate of triangle drift before one end and the wheel is set in the slide plate cell body, the spring box that is installed in recoil press spring is set on the vehicle frame at wheel rear, one end is set between spring box and slide plate cell body is connected the interior recoil press spring termination of the other end and spring box bonded assembly pull bar with stage clip residue termination, whereabouts in the slide plate cell body; Setting-in road surface fender on the triangle drift face that contacts with the road surface, the hinged anti-slipping chain that has the road surface fender on triangle drift lower end.

During brake, press the button switch in the operator's compartment, the electromagnet action makes the control hook break away from the triangle drift, under promoting, the whereabouts stage clip of triangle drift in gravity and slide plate cell body fall to the road surface rapidly, the wheel pad of advancing is braked from the road surface, and meanwhile the recoil press spring in the spring box is compressed.When reclaiming the triangle drift, the triangle drift is withdrawed from reversing earlier, recoil press spring in the spring box loosens and the triangle drift is mentioned, after being used to shake steel wire hook pew on the ratchet and living the triangle drift, shake hand ratchet rolling-in steel rope, mention the triangle drift and by slide plate compression whereabouts stage clip, until the triangle drift is carried go up to the control hook till, throw off the steel wire hook hand then.

Because the utility model is provided with the whereabouts stage clip and is provided with the road surface fender on the triangle drift in the slide plate cell body, thereby not only has the characteristics rapidly of braking, when brake, do not damage the superior part of ground-surface but also have.

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

Structural representation when Fig. 2 is the utility model emergency brake state.

Fig. 3 is the fixing birds-eye view of the spring box on the vehicle frame in the utility model.

Be further described below in conjunction with the technical characterictic of accompanying drawing the utility model most preferred embodiment.

Emergency brake arrangement on a kind of vehicle frame that is installed in rear wheel portion, be by being arranged on the preceding triangle drift (2) of wheel (1), fixedly be subjected to the electromagnet (4) of operator's compartment internal control button switch control on the vehicle frame (3), be subjected to electromagnet (4) but control and hook triangle drift (2) are gone up the control hook (6) of shackle (5), be arranged on a hand ratchet (7) on the vehicle frame (3) and an end hand ratchet (7) of reeling and go up the steel rope (8) that the other end has the hook hand and form.

On the vehicle frame (3) on every side mudguard (9), fix a slide plate cell body (10), the preceding hinged other end of triangle drift (2) of one end and wheel (1) and slide plate cell body (10) interior whereabouts stage clip (11) end bonded assembly slide plate (12) are set in the slide plate cell body (10), vehicle frame (3) at wheel (1) rear is gone up the spring box (14) that setting is installed in recoil press spring (13), one end is set between spring box (14) and slide plate cell body (10) is connected recoil press spring (13) the termination bonded assembly pull bar (15) that the other end and spring box (14) are interior with whereabouts stage clip (11) residue termination in the slide plate cell body (10); The road surface fender (16) that setting-in is made by rubber on triangle drift (2) face that contacts with the road surface, the hinged anti-slipping chain (17) that has road surface fender (16) on triangle drift (2) lower end.

In order to make the utility model that triangle drift (2) is fallen more rapidly on the road surface, the fixedly extension spring (18) of other end hook slide plate (12) of one end and vehicle frame (3) is set between vehicle frame (3) and slide plate (12), and this extension spring (18) is in tension before brake, and anti-slipping chain (17) termination, brake back is pressed into the back by wheel (1) and then is tension for relaxed state after all being pressed into by wheel.

If be provided with on the spring box (14) one with brake air valve (19) recoil press spring (13) interlock and that make this device the time vehicle self brake system be braked simultaneously with vehicle self brake system bonded assembly in brake, then braking effect is better.

In the present embodiment: the recoil press spring (13) in the spring box (14) can and connect by three groups of stage clips and forms, and each recoil press spring (13) is when maximum deformation quantity is 200mm, and its elastic force is 200 kilograms.And slide plate cell body (10) in whereabouts stage clip (11) deflection when 250mm, elastic force is 50 kilograms.
