Problems solved by technology

[0005] An object of the present invention is to provide a forklift work safety control system, which solves the problem of the lifting operation when the fork of the existing forklift is not in the horizontal position, which easily causes the goods to be squeezed and dropped, or when the mast of the forklift is in a forward tilting state. Defects that can cause goods to fall and lead to safety incidents
[0006] Another object of the present invention is to provide a forklift work safety control system, which solves the defect that the existing forklift forcibly increases the engine speed when the mast angle cannot be determined, which seriously affects the stability and operation safety of the whole vehicle

Embodiment 1

[0051] Embodiment 1: The present invention provides a forklift work safety control system, which is installed in the forklift control room, and is used to control the work of the forklift mast tilt angle data adjustment hydraulic subsystem, including: detection module 1, hydraulic subsystem 4, control Module 3 and the first input module 2, the control module is respectively connected to the detection module, the hydraulic subsystem and the first input module; the detection module is used to collect data on the height of the mast or the inclination angle of the mast and transmit it to the control module Among them: the hydraulic subsystem is used to receive instructions from the control module to drive the lifting of the mast 100 or adjust the inclination angle of the mast; the first input module is used to provide a signal for adjusting the leveling of the forklift or a normal operation mode signal; When the first input module gives a signal to adjust the leveling of the forkli...

Embodiment 2

[0053] Embodiment 2: as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention provides a forklift work safety control system, which is installed in the forklift control room, and is used to control the work of the forklift gantry tilt angle data adjustment hydraulic subsystem, including: detection module 1, hydraulic subsystem 4, control module 3 and the first input module 2 . Wherein, the detection module is used to collect the data of the height of the mast or the data of the inclination angle of the mast and transmit it to the control module; the detection module includes a mast height switch 3-3 and a sensor for the inclination angle of the mast 4-3. The hydraulic subsystem is used to receive instructions from the control module to drive the lifting of the mast or adjust the inclination angle of the mast; the hydraulic subsystem also includes a main oil circuit, a descending circuit and a multi-way valve assembly 5-3. The road valve...

Abstract

The invention provides a forklift work safety control system which comprises a detection module, a hydraulic subsystem and a first input module. The detection module is used for acquiring mast heightdata or mast inclination angle data and transmitting into a control module; the hydraulic subsystem is used for receiving a command of the control module so as to drive a mast to lift up and down or adjust an inclination angle of the mast; the first input module is used for providing a forklift adjusting and levelling signal or a normal operation mode signal; and when the first input module givesout the forklift adjusting and levelling signal, the control module adjusts the work of the hydraulic subsystem according to the mast height data or the mast inclination angle data acquired by the detection module so as to drive the mast to lift up and down or adjust the inclination angle of the mast. The forklift work safety control system provided by the invention solves the problems that sincean existing forklift fork is not at the horizontal position, cargoes are easily squeezed or damaged due to throw, or the cargoes fall down to cause accidents due to lifting operation when the mast ofthe forklift is at a forward leaning state.

Description

technical field [0001] The invention relates to the field of industrial vehicles, in particular to a forklift work safety control system. Background technique [0002] Forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. It is often used for the transportation of large objects in storage, and is usually driven by a fuel engine or a battery. [0003] The existing patent publication number is CN104943497 "A kind of reach-type forklift" patent document, which discloses a kind of reach-type forklift. During the operation of the forklift, the actual angle of the mast is difficult to accurately determine due to the obstacle of the driver's viewing angle. When the fork is not in a horizontal position when stacking goods, it is easy to cause the goods to be squeezed and damaged, and when the mast of the forklift is tilted forward, the lifting operation...
