Problems solved by technology

[0003] Since hydraulic handling forklifts are generally operated manually, the worker's handling experience is the key factor in determining whether the forklift is in place, which requires the factory to spend a long time training the operators, and the current forklift mast cannot judge the lifting Has reached the highest altitude

Embodiment 1

[0017] A forklift mast 100, the forklift mast 100 includes a mast body 1, a connecting frame 2 and a fork 3, the lower end of the mast body 1 is hinged to the forklift body, which can rotate relative to the forklift body, the The pallet fork 3 is connected to the mast body 1 through the connecting frame 2, and the connecting frame 2 is driven to move up and down through the lifting hydraulic cylinder 4 hinged at the lower end of the mast body 1, thereby driving the pallet fork 3 to move up and down, and the mast body 1 The tilting hydraulic cylinder 5 is driven to rotate so as to realize the adjustment of the angle when the cargo fork 3 is forked. A beam-type photoelectric sensor receiver 8, the through-beam photoelectric sensor transmitter 7 cooperates with the through-beam photoelectric sensor receiver 8 to realize whether the connecting frame 2 has moved up to the highest position.

Embodiment 2

[0019] Based on the first embodiment, both sides of the gantry body 1 are provided with through-beam photoelectric sensor transmitters 7 , and both sides of the connecting frame 2 are provided with through-beam photoelectric sensor receivers 8 .

Embodiment 3

[0021] On the basis of the first embodiment, the through-beam photoelectric sensor transmitter 7 is detachably arranged on the upper end of the gantry body 1 , and the through-beam photoelectric sensor receiver 8 is detachably arranged on the connecting frame 2 .

Abstract

The invention provides a forklift portal frame. The forklift portal frame comprises a portal frame body, a connecting frame and a pallet fork. The lower end of the portal frame body is hinged to a forklift body and can rotate relative to the forklift body. The pallet fork is connected with the portal frame body through the connecting frame. The connecting frame is driven by lifting hydraulic cylinders with the lower ends hinged to the portal frame body to move up and down, and therefore the pallet fork is driven to move up and down. The portal frame body is driven by inclined hydraulic cylinders to rotate so that the angle of the pallet fork during cargo forking can be adjusted. An opposite type photoelectric sensor emitter is arranged at the upper end of the portal frame body. An oppositetype photoelectric sensor receiver is arranged on the connecting frame. The opposite type photoelectric sensor emitter and the opposite type photoelectric sensor receiver cooperate to judge whether the connecting frame moves upwards to the highest position or not. By means of the forklift portal frame, it can be conveniently known that the pallet fork has been lifted to the limit height, and theforklift portal frame is suitable for being used by green hands.

Description

technical field [0001] The invention belongs to the field of special equipment, and in particular relates to a forklift mast. Background technique [0002] The hydraulic handling forklift is a dual-purpose vehicle for high-lift loading and unloading and short-distance transportation. The two fork plates are lifted by the hydraulic cylinder. Since it does not generate sparks and electromagnetic fields, it is especially suitable for vehicle loading and unloading and workshops, warehouses, docks, and stations. Loading and unloading of flammable, explosive and fire-prohibited items in warehouses, cargo yards and other places. This product has the characteristics of lifting balance, flexible rotation, and convenient operation. This is the reason why hydraulic forklifts are widely used. [0003] Since hydraulic handling forklifts are generally operated manually, the worker's handling experience is the key factor in determining whether the forklift is in place, which requires the f...
