Abstract
The invention discloses a flat heat traction vehicle cab collision buffer device, which comprises a slide rail groove, a pulley block and a safety bolt, wherein the slide rail groove is formed in a longitudinal beam of a flat head traction vehicle, the pulley block is glidingly arranged in the slide rail groove, in addition, a flat head cab is arranged on the pulley block, and the flat head cab is matched and fixed with a bolt hole formed in a cross beam of the flat head traction vehicle through the safety bolt. When the flat head traction vehicle generates head-on collision, the safety bolt is sheared through receiving the collision force effect, and a flat heat cab can backwards slide for a distance for buffering, so the damage to the flat head cab and the injury to personnel in the cab caused by the head-on collision can be relieved, and a good protection effect is realized on personnel in the cab.
Description
Technical field
The present invention relates to technical field of vehicle safety, especially relate to a kind of Flat heat traction vehicle cab collision buffer device.
Background technology
Existing tack tractor cab is directly fixed on the front portion of vehicle chassis by switching mechanism and portal frame.Tack tractor truck knock into the back or the head-on crash accident such as head-on collision time; if forward control cab is fixed on vehicle chassis, front portion does not have shock absorber; forward control cab meeting well damage, comparatively large to the personnel's harm in operator's compartment, good protection effect can not be played to the personnel in operator's compartment.
Summary of the invention
Not enough for prior art, technical matters to be solved by this invention is to provide a kind of Flat heat traction vehicle cab collision buffer device, to reach the object protecting forward control cab and indoor occupant safety when colliding.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Flat heat traction vehicle cab collision buffer device, comprise sliding-rail groove and assembly pulley and lock, described sliding-rail groove is located on the longeron of tack tractor truck, described assembly pulley slides and is located in sliding-rail groove, and forward control cab is provided with on assembly pulley, described forward control cab to be matched with the pin-and-hole on the crossbeam of tack tractor truck by lock and is fixed together.
Further, described forward control cab front portion is fixed together by the pulley of switching mechanism and assembly pulley middle front part, and forward control cab rear portion is fixed together by the pulley of portal frame and assembly pulley postmedian.
Described sliding-rail groove parallels with longeron.
Described switching mechanism is provided with pin-and-hole, by lock through the pin-and-hole on switching mechanism and crossbeam, switching mechanism and crossbeam is fixed together.
The present invention compared with prior art; have the following advantages: tack tractor truck is when head-on crash occurs; lock is subject to impact effect and is cut off; forward control cab can cushion slip one segment distance backward; thus alleviate frontal impact to the damage of forward control cab and to the injury of driving indoor occupant, driving indoor occupant is played a very good protection.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
Describe forward and backward position relationship in the present invention, the headstock direction of its tack tractor truck is front, after tailstock direction is.
As shown in Figures 1 to 6, this Flat heat traction vehicle cab collision buffer device is arranged between the chassis of forward control cab and tack tractor truck, and tack tractor truck is when head-on crash occurs, and forward control cab 3 can cushion slip one segment distance backward.
This device comprises that sliding-rail groove 7 and assembly pulley 6 and lock 8, two sliding-rail groove 7 are parallel to be fixed on the longeron 1 of tack tractor truck, and sliding-rail groove 7 also parallels with longeron 1, and assembly pulley 6 slides and is located in sliding-rail groove 7.Wherein, assembly pulley 6 comprises eight pulleys, eight pulleys all can in sliding-rail groove slide anteroposterior.
Forward control cab 3 front portion is fixed together by four pulleys of switching mechanism 4 with assembly pulley 6 middle front part, and forward control cab 3 rear portion is fixed together by four pulleys of portal frame 5 with assembly pulley 6 postmedian.Namely the bottom of forward control cab 3 is fixed on assembly pulley 6 by switching mechanism 4 and portal frame 5.
The crossbeam 2 of switching mechanism 4 and tack tractor truck is equipped with pin-and-hole 9, is coordinated with two pin-and-holes 9 by lock 8, the chassis of forward control cab 3 with tack tractor truck is fixed together.
When tack tractor truck generation head-on crash, lock 8 is subject to impact effect and is cut off; Because forward control cab is subject to the effect of external force, forward control cab is slided backward in sliding-rail groove by switching mechanism and portal frame top sheave group, owing to having certain distance between the operator's compartment of tack tractor truck and trailer, forward control cab can slide backward certain distance, thus alleviate the injury of collision to personnel in forward control cab, improve the safety performance of tack tractor truck.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that design of the present invention and technical scheme are carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
