Abstract
The invention discloses a suspension locking system for a fork lift. The suspension locking system comprises an electromagnetic valve, wherein the electromagnetic valve is connected with a balancing oil cylinder via a suspension locking device; the balancing oil cylinder is connected with an upper swinging bridge mechanism; the upper swinging bridge mechanism comprises two side arms and one transverse arm; two ends of the transverse arm are connected with a vehicle frame; a lower swinging bridge mechanism comprises two side arms and two transverse arms; the middle of the transverse arm of the upper swinging bridge mechanism is connected with the middle of the transverse arm at one end of the lower swinging bridge mechanism via a damping spring; a balancing wheel assembly is arranged below the lower swinging bridge mechanism, and is connected with the vehicle frame via a shaft passing through the side arms of the lower swinging bridge mechanism; and the middle of the transverse arm at the other end of the lower swinging bridge mechanism is connected with the balancing wheel assembly via another damping spring. Due to the suspension locking system, the whole fork lift can run on different pavements smoothly and safely, that is, the work safety of the fork lift is improved, operating staff is protected to a larger extent, and the purpose of protecting the safety of a driver during operation is achieved.
Description
Technical field
The present invention relates to fork truck technical field, be specifically related to a kind of fork truck hanging lock fixed system.
Background technology
The advantages such as fork truck is mechanical equipment conventional in handling work, and wherein batter fork lift truck is little with its pollution, adaptation occasion is many are more and more applied, and its power resources are exactly the storage battery be assemblied on fork truck.Along with social development, in order to improve the work efficiency of electri forklift, it is more and more higher that the moving velocity of fork truck is designed, and travel under appearing at various road conditions, but along with the raising of moving velocity and becoming increasingly complex of road conditions, also more and more higher to the stability requirement of electri forklift, therefore, the electri forklift used under solution can adapt to high-speed, multi-path condition expense is necessary.
Summary of the invention
The object of the invention is to be to provide a kind of fork truck hanging lock fixed system, it can keep car load in the steady of different road surface and safety, improves fork truck job security, protects operating personal to a greater extent, reaches the object that protection driver safety carries out operating.
The object of the invention is to be achieved through the following technical solutions: it comprises electromagnetic valve, described electromagnetic valve is connected with balancing cylinder by hanging blocking device, described balancing cylinder is connected with upper pendulum bridge mechanism, upper pendulum bridge mechanism is made up of two side arms and a transverse arm, the two ends of transverse arm are connected with vehicle frame, described bottom bridge mechanism is made up of two side arms and two transverse arms, the centre of described upper pendulum bridge mechanism transverse arm is connected with in the middle of the transverse arm of bottom bridge mechanism one end by damping spring, balance wheel assembly is provided with below bottom bridge mechanism, balance wheel assembly is connected with vehicle frame through after bottom bridge mechanism two side arms by an axle, the centre of described bottom bridge mechanism other end transverse arm is also connected with balance wheel assembly by damping spring.
The present invention it can keep car load different road surface steadily and safety, improve fork truck job security, protect operating personal to a greater extent, reach the object that protection driver safety carries out operating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural upright schematic diagram of the present invention.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is further described in detail.
Embodiment: as shown in accompanying drawing 1-2, it comprises electromagnetic valve 1, described electromagnetic valve 1 is connected with balancing cylinder 3 by hanging blocking device 2, described balancing cylinder 3 is connected with upper pendulum bridge mechanism 4, upper pendulum bridge mechanism 4 is made up of two side arms and a transverse arm, the two ends of transverse arm are connected with vehicle frame, bottom bridge mechanism 5 is provided with below upper pendulum bridge mechanism 4, described bottom bridge mechanism 5 is made up of two side arms and two transverse arms, the centre of described upper pendulum bridge mechanism 4 transverse arm is connected with in the middle of the transverse arm of bottom bridge mechanism 5 one end by damping spring 7, balance wheel assembly 6 is provided with below bottom bridge mechanism 5, balance wheel assembly 6 is connected with vehicle frame through after bottom bridge mechanism 5 two side arms by an axle, the centre of described bottom bridge mechanism 5 other end transverse arm is also connected with balance wheel assembly 6 by damping spring 7.
When driving a vehicle, electromagnetic valve controls the flexible of balancing cylinder by hanging blocking device, thus drive the parallelogram motion of upper pendulum bridge mechanism and bottom bridge mechanism composition, thus further adjustment balance wheel axle assembly keep car load different road surface steadily and safety, upper pendulum bridge mechanism with between bottom bridge mechanism, the damping spring that is connected between bottom bridge mechanism with balance wheel assembly can reduce the vibration amplitude be subject in balance wheel axle assembly adjustment process.
Above-described embodiment is one of the present invention preferably scheme, not does any pro forma restriction to the invention of this reality, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
