Abstract
The invention discloses a device with a cargo active protection function for a pallet fork. The device comprises a distance measuring sensor, a forklift master controller and a hydraulic control forwards moving system. The distance measuring sensor is installed on the pallet fork, or when a forwards moving type forklift is a portal forwards moving type forklift, the distance measuring sensor can further be installed on a portal. The forklift master controller is electrically connected with the distance measuring sensor and the hydraulic control forwards moving system. The distance measuring sensor is used for collecting a distance signal of the pallet fork and a load. The forklift master controller compares the distance signal with a distance signal pre-recorded to determine a control signal of the required speed of the pallet fork. The hydraulic control forwards moving system receives the control signal and controls the pallet fork or the portal to move up and down at the required speed through the control signal. According to the device with the cargo active protection function for the pallet fork, control of the device is prior to operation of a driver, when the pallet fork is close to the load, the forking speed can be automatically adjusted through the device no matter how the driver operates the moving speed of the pallet fork, and no collision between the pallet fork and the load happens.
Description
Technical field
The present invention relates to the device of the goods of a kind of pallet fork actively defencive function.
Background technology
Reach truck is industrial transportation vehicle, the one of warehousing forklift, refer to member pallet cargo is loaded and unloaded, the wheeled carrying vehicle of reach of stacking and short distance hauling operation.
It is different from common fork truck, the door frame of reach truck or goods shelf can move forward and backward, and wherein door frame reach truck refers to that during operation, door frame drives pallet fork forward moving, and outside reaching front-wheel, fork takes or puts down goods, during walking, pallet fork band goods is regained, and makes center of gravity of goods in supporting surface；And pallet fork forward moving type fork truck refers to that shelf (stretching structure) drive pallet fork forward moving to carry out operation to front-wheel, during walking, shelf drive pallet fork to be retracted in supporting plane.
Existing reach truck is in fork picking thing process, when pallet fork is close to load (goods or pallet), driver have to reduce pallet fork speed or adjust pallet fork position, owing to driver's cabin is normally at the rear of forklift door frame, driver is difficult to judge that the concrete distance of pallet fork rear portion distance load is how many, it is thus desirable to driver's high concentration and there is good operant skill guarantee pallet fork do not touch load, so not only expend the energy of driver, and inefficiency.
In view of this, the present inventor develops the device of the goods actively defencive function of a kind of pallet fork, solves drawbacks described above, and this case thus produces.
Summary of the invention
It is an object of the invention to provide the device of the goods of a kind of pallet fork actively defencive function; it takes, at fork, the translational speed that can automatically control pallet fork in loading process; do not need driver's control deliberately, and will not collide with load, improve security performance and work efficiency.
In order to reach above-mentioned purpose, the solution of the present invention is:
The device of the goods of a kind of pallet fork actively defencive function, including distance measuring sensor, fork truck master controller and hydraulic control reach system；Distance measuring sensor is arranged on pallet fork, or distance measuring sensor can also be arranged on door frame when reach truck is door frame shift-forward type；Fork truck master controller electrically connects with distance measuring sensor and hydraulic control reach system respectively, distance measuring sensor is for gathering the distance signal of pallet fork and load, and this distance signal and its distance signal recorded in advance are compared to determine the control signal of speed needed for pallet fork by fork truck master controller；Hydraulic control reach system receives this control signal, controls pallet fork by this control signal or door frame does movable under this required speed.
Described distance measuring sensor is electrically connected by mode and the fork truck master controller of wireless connections.
Being provided with radio induction charging system on the vehicle frame of described door frame or fork truck, distance measuring sensor can carry out radio induction charging by this radio induction charging system.
After adopting such scheme, the control of this device has precedence over the operation of driver, when pallet fork is close to load, the not translational speed of tube driver how to operate pallet fork, or no matter the initial range of pallet fork and load how, it is automatically adjusted, such as through this device, the speed that fork takes, with load, any collision will not occur, improve security performance and work efficiency.

Label declaration:
Distance measuring sensor 1, fork truck master controller 2, hydraulic control reach system 3, pallet fork 4, door frame 5, vehicle frame 6.
Detailed description of the invention
In order to technical scheme is explained further, below by specific embodiment, the present invention will be described in detail.
As Figure 1-3, it is the device of the goods actively defencive function of a kind of pallet fork 4 that the present invention discloses, including distance measuring sensor 1, fork truck master controller 2 and hydraulic control reach system 3；Distance measuring sensor 1 is arranged on pallet fork 4, or when reach truck is door frame 5 shift-forward type, distance measuring sensor 1 can also be arranged on door frame 5 (as shown in Figure 3)；Fork truck master controller 2 electrically connects with distance measuring sensor 1 and hydraulic control reach system 3 respectively, distance measuring sensor 1 is for gathering the distance signal of pallet fork 4 and load, and this distance signal and its distance signal recorded in advance are compared to determine the control signal of speed needed for pallet fork 4 by fork truck master controller 2；Hydraulic control reach system 3 receives this control signal, controls pallet fork 4 by this control signal or door frame 5 does movable under this required speed.
Owing to this device controls pallet fork 4 or the motion of door frame 5 either directly through fork truck master controller 2, therefore there is the operation having precedence over driver, effectively prevent any interference of driver, when pallet fork 4 is close to load, the initial range of the translational speed of tube driver how to operate pallet fork 4 and no matter pallet fork 4 and load is not how, it is automatically adjusted, such as through this device, the speed that fork takes, and with load, any collision will not occur, improve security performance and work efficiency.
Owing to door frame 5 and/or pallet fork 4 are moveably mounted on reach truck, if the mode adopting entity connects distance measuring sensor 1 and fork truck master controller 2, connecting device is more complicated, and cost is high, the mode of wireless connections is therefore adopted distance measuring sensor 1 and fork truck master controller 2 to be electrically connected.
In order to make distance measuring sensor 1 will not quit work because of power-off, being provided with radio induction charging system (not shown) on the door frame 5 or vehicle frame of reach truck, distance measuring sensor 1 carries out radio induction charging by this radio induction charging system.Connection for the ease of entity circuit, preferentially select installation radio induction charging system on vehicle frame 6, when need to charge, pallet fork 4 is dropped to bottom can farthest be charged, owing to when having a rest night or be unloaded, pallet fork 4 all can drop to bottom, therefore without worrying that distance measuring sensor 1 can lose efficacy because of power-off.
Have on fork truck master controller 2 existing market of above-mentioned speed controlling and horizontal level control to be readily available, it is not necessary to again develop.
The product form of above-described embodiment and the graphic and non-limiting present invention and style, any person of an ordinary skill in the technical field is to its suitably change done or modifies, and all should be regarded as the patent category without departing from the present invention.
