Description

Gravity self-locking formula fire fighting truck tilt-up door

Technical field

This utility model relates to fire-fighting equipment, is specifically related to a kind of fire fighting truck tilt-up door.

Background technology

Fire fighter is during using fire fighting truck fire-fighting fire extinguishing, it is often necessary to is opened by tilt-up door and picks and places fire-fighting equipment, Existing fire fighting truck tilt-up door majority uses air spring to control it and automatically turns on, and only a few also has employing hydraulic jack or cylinder, mesh Be all prevent tilt-up door because of gravity self-return close.Air spring opening angle is limited by air spring thrust, and gas bullet Spring can only control tilt-up door and open maximum angle, it is impossible to arbitrarily open certain angle, and it is the most convenient to use.Air spring Air pressure inside decline back pressure can be gradually reduced after a long time use, and the too small equipment of taking of overhead door opening angle can be inconvenient, Tilt-up door can cannot be automatically turned under serious conditions.When air spring thrust is big, bigger active force can be produced to installing hinge, hold Easily making hinge get loose, there is potential safety hazard, also easily cause opening angle excessive, the following terrain clearance of overhead door increases the most therewith, If neighbouring nothing tramples object, it is difficult to close overhead door.Hydraulic mechanism and cylinder can make overhead door stop at any time in opening procedure Motion, but it involves great expense, and maintenance cost is big, and external pipeline is easily collided with by equipment in car, causes mechanical damage, and takies Space is relatively big, therefore and is infrequently used.

Summary of the invention

This utility model for existing fire fighting truck tilt-up door air spring mechanism thrust big time be easily damaged hinge, thrust hour Being not easy to open tilt-up door, hydraulic cylinder and cylinder mechanism cost high, maintenance cost is big, easily causes mechanical damage, takes up room Big drawbacks described above, it is provided that a kind of gravity self-locking formula fire fighting truck tilt-up door.

Technical solution of the present utility model is: it includes tilt-up door, two Upturning door hinge joint chairs, two gravity self-lockings Plate and detent mechanism, two Upturning door hinge joint chairs both sides with tilt-up door top respectively are hinged and disappear for being arranged on by tilt-up door On anti-car car body, the identical height and position that two gravity self-locking plates lay respectively at two Upturning door hinge joint chairs is arranged on fire fighting truck car On body, detent mechanism is made up of hands tommy bar, two lacing wires, two flexible locks and several pulleys, and the two ends of hands tommy bar are divided Be not transversely provided with towards identical torque arm, hands tommy bar be positioned at tilt-up door towards outside the most parallel with tilt-up door, hands tommy bar The middle part of two torque arm respectively by hinge in tilt-up door lower position, two flexible locks respectively by overcoat, stage clip and Stop pin is constituted, and two one end stretching lock overcoat are perpendicular to the door body direction of tilt-up door and are separately fixed at inside tilt-up door door The position corresponding with two gravity self-locking plates, compression spring sleeve is contained in overcoat, one end slip cap of stop pin be contained in overcoat with Match in one end of stage clip, the other end is exposed to outside overcoat match, on stop pin with each self-locking grooves on two gravity self-locking plates Be transversely provided with lacing wire and connect seat, the two ends of two lacing wires be connected to the lacing wire of tilt-up door the same side connect on seat and torque arm with Hands tommy bar be connected the other end, each pulley be rotatably installed on tilt-up door along the trend of two lacing wires respectively match with lacing wire for Lacing wire guides, and with hands switching hands tommy bar, hands tommy bar is connected seat can be pulled stop pin in overcoat by torque arm, lacing wire, lacing wire Retraction departs from the self-locking grooves on gravity self-locking plate.

Of the present utility model have the technical effect that it solve existing fire fighting truck tilt-up door use gas-spring pressure big time easy Damaging hinge, be not easy to close the door, pressure hour tilt-up door opening angle is big not, is not easy to pick and place the defect of equipment.It is permissible Turn on Shou Dong and open, the gravity of tilt-up door when being opened to suitable angle, can be utilized to realize self-locking, it is achieved that open angle with The purpose of meaning.Both being easy to pick and place equipment, and also allowed for closing tilt-up door, more convenient to use, using effect is more preferable.
