Abstract
A hydraulic locking lock body for an automobile cab is composed of a hydraulic spring cylinder, a fixed limiting pin, a rest spring, a rotary fixing pin, a locking block and a locking body base. The hydraulic spring cylinder, the fixed limiting pin and the rotary fixing pin are installed on the lock body base. After pressure oil is led into the hydraulic spring cylinder, the locking block is jacked and made to rotate around the rotary fixing pin so as to open the locking lock body. When the cab descends, oil is discharged from an oil port of the spring cylinder, a plunger of the spring cylinder resets under the effect of the reset spring and drives the locking block to conduct reset locking at the same time, and the fixed limiting pin is fixed onto the lock body base to prevent the locking block from rotating upwards. The hydraulic locking lock body for the automobile cab is opened through the hydraulic spring cylinder, the locking lock body locks a lock column below a frame to form a self-locking condition, so that it is guaranteed that the cab is reliably locked and cannot be disengaged, dangers are avoided, and the safety and comfort requirements of growing heavy duty automobiles are met.
Description
Technical field
The present invention relates to technical field of automobile parts, relate in particular to automobile cab locking lock body technical field.
Background technology
Automobile in motion, due to the generation impulsive force that jolts, can not throw off, and avoids causing danger by operator's compartment reliably locking.Heavily block automotive engine and be arranged on the below of operator's compartment, when keeping in repair, safeguarding, need lift operator's compartment.During in normal condition, must reliable locking guarantee traffic safety at operator's compartment.Conventional mechanical lock lock body, the large inconvenient operation of crack force, safety factor is low.
Summary of the invention
The problems referred to above that exist for the mechanical lock lock body of operator's compartment in order to overcome tradition, the invention provides the tight lock body of a kind of hydraulic lock for automobile cabin.
The technical scheme that the present invention adopted is for achieving the above object: the tight lock body of hydraulic lock for automobile cabin, by hydraulic spring grease cup cylinder, fixing locating dowel pin, retracing spring, rotation set pin, lock dog and lock body base composition, hydraulic spring grease cup cylinder, fixing locating dowel pin and rotation set pin are arranged on lock body base, after hydraulic spring grease cup cylinder passes into pressure oil, jack-up lock dog makes it around fixing swivel pin Unscrew locking lock body, spring cylinder hydraulic fluid port draining when operator's compartment declines, spring cylinder plunger resets and drives the lock dog locking that simultaneously resets under action of reset spring, fixing locating dowel pin is fixed on limitation lock piece on lock body base and rotates up.
Lock is installed on vehicle frame, and operator's compartment is dropping to while approaching lock, and lock is along with slideway is depressed the lock dog of locking lock body, and after falling to putting in place, lock dog is at action of reset spring position locking lock next time.
The tight lock body of hydraulic lock for automobile cabin of the present invention, uses hydraulic spring grease cup cylinder to open, and locking lock body pins vehicle frame below lock, and form condition of self-locking, the reliable locking of assurance operator's compartment can not be thrown off, and avoids causing danger, and meets growing traction engine safety, comfort type demand.
Accompanying drawing explanation
Fig. 1 is the tight lock body structure figure of hydraulic lock for automobile cabin of the present invention.
The specific embodiment
The tight lock body structure of hydraulic lock for automobile cabin of the present invention as shown in Figure 1, is mainly made up of hydraulic spring grease cup cylinder (1), fixing locating dowel pin 2, retracing spring 3, rotation set pin 4, lock dog 5, lock body base 6.Hydraulic spring grease cup cylinder 1 is connected on lock body base 6 by nut, after passing into pressure oil, jack-up lock dog 5 makes it around fixing swivel pin 4 Unscrew locking lock bodies, spring cylinder hydraulic fluid port draining when operator's compartment declines, spring cylinder plunger resets and drives lock dog 5 locking that simultaneously resets under retracing spring 3 effect, fixing locating dowel pin 2 is fixed on lock body base, and restriction lock dog rotates up.Lock 6 is locked in lock body, due to lock dog be fixed locating dowel pin 2 and hydraulic spring grease cup cylinder 1 spacing, can not rotate up, cause lock 6 not move up.The inside rotational force of lock dog 5 forms self-locking in Self-locking angle, can not inwardly rotate, and realizes and locking thereby operator's compartment is locked on vehicle frame.
Utilize the manual power source of turnover device for automobile cab to open hydraulic pressure lock body, operation pressure when driver's cab turnover is 23MPa, and the response pressure of hydraulic pressure lock body is 12MPa, first opens lock body in driver's cab turnover process, guarantees the reliable of work.Hydraulic pressure lock body is arranged on the below of operator's compartment rotating part, and lock is arranged on vehicle frame, and operator's compartment is dropping to while approaching lock, lock is along with slideway is depressed the lock dog of locking lock body, after falling to putting in place, lock dog is at action of reset spring position locking lock next time, thus locking operator's compartment.Lock cannot be moved by slideway restriction left and right, is in all the time in Self-locking angle and forms self-locking while moving up, guarantees that traffic safety can not open by mistake.The crack force of hydraulic pressure lock body is 135KG, and the opening travel of spring oil cylinder is 8mm, and the unlatching anglec of rotation of lock dog is 15 °.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
