Detailed Description

Further refinements will now be made on the basis of the representative embodiment shown in the figures. It should be understood that the following description is not intended to limit the embodiments to one preferred embodiment. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the embodiments as defined by the appended claims.

In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in accordance with the embodiments. Although these embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments, it is to be understood that these examples are not limiting, such that other examples may be used and that corresponding modifications may be made without departing from the spirit and scope of the embodiments.

In particular, reference is made to the accompanying drawings. Fig. 1, fig. 2 and fig. 3, fig. 1 and fig. 2 show an anti-collision safety system for a battery forklift, which is used for solving the problem that the current forklift is not provided with an anti-collision system, so that the occurrence of accidents easily causes the occurrence of accidents of the forklift or casualties.

Specifically, the system comprises a forklift body 1, a forklift controller assembly 2 and a display suite 15 are arranged on the forklift body 1, and the display suite 15 is connected with the forklift controller assembly 2; the forklift controller assembly 2 comprises a walking controller 3 and an oil pump controller 4, wherein the walking controller 3 is used for controlling whether a walking motor enters a braking state, and the oil pump controller 4 is used for controlling whether a lifting oil pump enters the braking state; the walking controller 3 and the oil pump controller 4 issue control commands through the forklift control assembly. Be provided with three evenly distributed's distance sensor 5 at the fork truck rear side, be provided with altitude sensor 6 at the fork truck top, fork truck body 1 still is provided with crashproof signal transceiver 7, crashproof signal transceiver 7 links to each other with fork truck controller subassembly 2, distance sensor 5 and altitude sensor 6 link to each other with crashproof signal transceiver 7, crashproof signal transceiver 7 is used for transmitting distance sensor 5 and altitude sensor 6's signal to the controller subassembly, then, the controller subassembly sends to walking controller 3 and oil pump controller 4 after with signal processing.

The display assembly 15 described above is used for control information of the forklift controller assembly 2, and other related information. Such as distance warning, altitude warning, etc.

Specifically, 3 distance sensor 5's information is buried in anticollision signal transceiver 7 department, and when the vehicle had the signal of retreating, 3 distance sensor 5 were effective, and anticollision signal transceiver 7 carries out distance detection through the ultrasonic wave, and when finding that the barrier distance reaches alarm set value 3.5M, feedback alarm signal 1 immediately for fork truck controller subassembly 2, walking controller 3 adjustment motor rotational speed in the fork truck controller subassembly 2 carries out appropriate speed reduction. When the vehicle collides with an obstacle by 1.5M, an alarm signal 2 is fed back to the forklift controller assembly 2 immediately, and the walking controller 3 adjusts the motor to enter a braking state. Thereby achieving the purpose of preventing vehicle collision or reducing loss caused by vehicle collision.

When a lifting assembly (mainly the movement of a pallet fork 10 on a portal frame 8) of the forklift works, a height sensor is effective, when the lifting assembly runs to a set height, a sensing signal is directly sent to a forklift controller assembly 2, an oil pump controller 4 in the forklift controller assembly 2 receives the signal, an oil pump motor is immediately adjusted to enter a braking state, the lifting assembly is forbidden to act, so that the height is limited, and meanwhile, the forklift moves forwards and backs up to reduce the speed, so that collision of lifting oil cylinders is prevented. The arrangement directly avoids the problem that the lifting limit of the existing forklift is usually realized by mechanically limiting through a lifting oil cylinder, and the performance and the service life of the oil cylinder are directly influenced by strong collision.

As a further improvement of the above scheme, as shown in fig. 3 and indicated by a dashed line frame in fig. 2, a mast 8 is provided on the forklift body 1, then a limit switch 9 is provided on the upper portion of the mast 8, the limit switch 9 is connected with the forklift controller assembly 2, the position of the limit switch 9 is correspondingly matched with a pallet fork 10 moving up and down on the mast 8, and the lift oil pump is controlled to be switched to a slow-speed rising state after the pallet fork 10 reaches the limit switch 9, so that the occurrence of oil pump collision caused by insufficient braking of a subsequent lift oil pump is avoided. This arrangement is such that the latter half of the lifting process is set to a slow running state.

Above-mentioned scheme has only solved fork truck part problem. On the basis, a flow sensor 11 is arranged on the portal frame 8, the flow sensor 11 is arranged on the portal frame 8 through a movable frame 12, the flow sensor 11 rises up and down along with the rise of the goods on the fork 10, and the flow sensor 11 is connected with the anti-collision signal transceiver 7. The purpose of the flow sensor 11 is to detect an obstacle above the load when the load is lifted, so as to prevent the load on the fork 10 from colliding. The adjustable shelf 12 is including setting up vertical pole 13 on portal 8 and the horizon bar 14 that sets up perpendicularly and extend to fork 10 top with vertical pole 13, and flow sensor 11 sets up on horizon bar 14, and vertical pole 13 inserts and locates in the preformed hole on portal 8, and the goods rises to rise the back top and is lifted horizon bar 14 and drive flow sensor 11 position and improve. More specifically, the vertical rod 13 is inserted into one insertion tube, and the vertical rod 13 is slidably engaged with the insertion tube, so that the vertical rod 13 can be lifted along the insertion tube by the horizontal rod 14. The raising of the horizontal bar 14 follows the raising of the load. In order to improve the smoothness of the rising of the vertical rod 13, an auxiliary mechanism can be added to help the vertical rod 13 rise, so that the operation of the goods on the horizontal rod 14 is a starting switch, and the starting switch starts the corresponding auxiliary mechanism to drive the vertical rod 13 to rise.

When fork truck loaded the goods, more exactly when rising the goods, will carry out effective monitoring to the barrier of goods top, avoid the barrier to reach and cause the collision to the goods, cause loss of property.
