Abstract
The invention discloses a novel hydraulic excavator multifunctional auxiliary tool controller which comprises a pilot control valve and a fixed plate with an inserting opening formed in the middle portion. The upper portion of the pilot control valve penetrates through the inserting opening and is fixed on the fixed plate. The top end of the pilot control valve is connected with a pedal through a connecting block. The novel hydraulic excavator multifunctional auxiliary tool controller is characterized in that the fixed plate is provided with a locking support fixedly connected with the fixed plate through bolts, a hinge pin sleeve tube with a clamp groove is arranged on the locking support, a hinge pin with a drive rod and movably connected with the hinge pin sleeve tube is arranged in the hinge pin sleeve tube, the drive rod is correspondingly clamped with the clamp groove and an inserting hole corresponding to the hinge pin is formed in the lower portion of the pedal. The novel hydraulic excavator multifunctional auxiliary tool controller is reasonable in structure. Due to the fact that the locking support is fixed on the fixed plate through the bolts and the hinge pin is corresponding to the inserting hole in the lower portion of the pedal, in the process of use, the drive rod only needs to be moved so that the hinge pin is inserted in or pulled out of the inserting hole in the lower portion of the pedal, namely, the purpose of locking or opening the multifunctional auxiliary tool controller is achieved. The novel hydraulic excavator multifunctional auxiliary tool controller solves the technical problems that installation process is time-consuming, labor-consuming, large in labor intensity and poor in safety performance.
Description
Technical fieldThe invention belongs to the controller for excavators technical field, be specifically related to the multi-functional accessory controller of a kind of hydraulic excavator.
Background technologyIn prior art, hydraulic excavating machine multifunctional accessory controller is mainly used in excavator and the special operation such as shears, the impact that is subjected to itself volume is large, weight is large, the installing space that needs is large, made originally and seemed narrower and small with regard to the little excavator cab in space, incompatible with driver's cabin elegant in appearance, installation process wastes time and energy; And the spring rate of pilot valve is large, requires great effort during driver's operation, and labour intensity is large; Simultaneously, when multi-functional accessory controller does not use, be subjected to the impact of locking device structure, if the driver steps on because of carelessness on the pedal of controller, thereby can cause the controller maloperation to cause the complete machine cisco unity malfunction, cause unnecessary loss, excavator handling safety coefficient is reduced greatly.
Summary of the inventionThe objective of the invention is to solve prior art and have that installation process wastes time and energy, labour intensity large and the technical problem of poor stability, provide a kind of hydraulic excavator multi-functional accessory controller, to overcome the deficiencies in the prior art.
The multi-functional accessory controller of a kind of hydraulic excavator of the present invention, it comprises the fixed head of pilot-actuated valve and middle part carrying spigots; The top of described pilot-actuated valve is passed socket and is bolted on fixed head; The top of described pilot-actuated valve is connected with pedal by contiguous block; Its main points are that described fixed head is provided with the lock bracket that is fixedly connected with it by bolt; Described lock bracket is provided with the bearing pin sleeve pipe with draw-in groove; Be provided with the bearing pin with driving lever with its flexible connection in described bearing pin sleeve pipe; Described driving lever and the mutual corresponding clamping of draw-in groove; The bottom of described pedal is provided with the jack corresponding with bearing pin.
The present invention is novel in design, rational in infrastructure, because lock bracket is bolted on fixed head, and bearing pin is corresponding with the jack of pedal bottom, during use, only need stir driving lever and bearing pin be inserted or transfers to the jack of pedal bottom, the purpose that can reach locking or open multi-functional accessory controller.The invention solves that the prior art installation process wastes time and energy, labour intensity is large and the technical problem of poor stability.

Fig. 2 is lock-out state structural representation right view of the present invention;
Fig. 3 is opening structural representation stereogram of the present invention;
Fig. 4 is opening structural representation right view of the present invention;
Fig. 5 is that the present invention disassembles status architecture signal enlarged drawing.
In figure 1, contiguous block 2, pedal 3, driving lever 4, fixed head 5, pilot-actuated valve 6, bearing pin sleeve pipe 7, draw-in groove 8, bearing pin 9, lock bracket 10, socket 11, jack
The specific embodimentAccording to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it comprises the fixed head 4 of pilot-actuated valve 5 and middle part carrying spigots 10 the present invention; The top of described pilot-actuated valve 5 is passed socket 10 and is bolted on fixed head 4; The top of described pilot-actuated valve 5 is connected with pedal 2 by contiguous block 1; Described fixed head 4 is provided with the lock bracket 9 that is fixedly connected with it by bolt; Described lock bracket 9 is provided with the bearing pin sleeve pipe 6 with draw-in groove 7; Be provided with the bearing pin 8 with driving lever 3 with its flexible connection in described bearing pin sleeve pipe 6; Described driving lever 3 and the mutual corresponding clamping of draw-in groove 7; The bottom of described pedal 2 is provided with the jack corresponding with bearing pin 8 11.
Operating principle of the present invention: hydraulic crawler excavator inserts bearing pin by driving lever in the jack of pedal bottom, i.e. lockable when not using multi-functional accessory operation; In this state, the driver ride can be relieved on pedal the driving excavator excavate, the operation such as loading and unloading, can not touch pilot-actuated valve and produce maloperation initiation potential accident; Hydraulic crawler excavator is when using multi-functional accessory operation, the driver can transfer to bearing pin by driving lever the jack of pedal bottom, this moment, state was unlock state, and the driver can arbitraryly treadle, and drove excavator and the special operation such as sheared.Owing to adopting the little pilot-actuated valve of spring stiffness, compare with traditional pilot-actuated valve that required to control strength little, so that driver's long working can not felt yet is tired.
Owing to can inserting forward locking in the draw-in groove of driving lever on the bearing pin sleeve pipe or transfering to backward and open, bearing pin after locking can firmly lock pedal, can not allow pilot-actuated valve seesaw, do not have motion so the accessory on main valve is controlled spool, so complete machine can work.
