DETAILED DESCRIPTION

[0036] In the related art, the fork truck front fork is made of smooth plane steel plate, and when working, the fork leg is insufficiently inserted, i.e., not inserted in place, which easily leads to goods toppling.

[0037] Based on this, referring to Figures 1 to 7 ​The utility model provides a kind of fork truck capable of preventing goods from toppling, comprising: front fork 1, the front section of front fork 1 is provided with limiting groove 2;Transmitter 4 and receiver 5, transmitter 4 and receiver 5 are respectively installed on the two side walls of limiting groove 2, and transmitter 4 is located on the receiving path of receiver 5;And seesaw type limiter 3, seesaw type limiter 3 is pivotally supported in limiting groove 2 by shaft 31, the rear end of seesaw type limiter 3 is load sensing part 32 for receiving the pressure of goods pallet 6, the front end of seesaw type limiter 3 is path blocking part 33 for the on-off of receiving path under the action of the pressure of goods pallet 6 received by load sensing part 32, and path blocking part 33 can be elastically deformed. Figure 3 From the perspective of top view, transmitter 4 and receiver 5 are respectively located on the two sides of path blocking part 33.

[0038] When using, goods are piled on goods pallet 6. The fork truck of the utility model can judge whether the goods pallet inserted by the front fork is in place according to the on-off of the receiving path, and can solve the problem that the lifted goods topple due to the non-in-place of goods pallet.

[0039] Specifically, referring to Figure 4 and Figure 5 , when the front fork 1 is not inserted into goods pallet 6, seesaw type limiter 3 is in an inclined state, load sensing part 32 is exposed from above limiting groove 2, and path blocking part 33 blocks the receiving path.

[0040] When the front fork 1 is inserted into goods pallet 6 but not in place, goods pallet 6 presses load sensing part 32 downward, drives path blocking part 33 to rotate towards the direction close to goods pallet 6, and path blocking part 33 blocks the receiving path.

[0041] Referring to Figure 6 , when goods pallet 6 is in place, path blocking part 33 pops out of limiting groove 2 to open the receiving path.

[0042] In an embodiment, transmitter 4 is an infrared transmitter, and receiver 5 is an infrared receiver.

[0043] In an embodiment, referring to Figure 1 , the fork truck comprises a controller 7 and one or more visual indicators, and the one or more visual indicators, transmitter 4 and receiver 5 are electrically connected with controller 7 respectively.

[0044] In an embodiment, referring to Figure 1 , the one or more visual indicators comprise red visual indicator 81 and green visual indicator 82.

[0045] Red visual indicator 81 is bright to indicate that goods pallet is not inserted in place, at this time, path blocking part 33 blocks the receiving path.

[0046] The green visual indicator 82 is bright when the goods pallet is inserted into position, at which time the path blocking part 33 opens the receiving path.

[0047] In an embodiment, referring to Figure 1 The forklift also comprises a voice broadcaster 9, which is electrically connected to the controller 7.

[0048] In this embodiment, the controller 7 controls the voice broadcaster 9 to broadcast a voice when the goods pallet is inserted into position.

[0049] In an embodiment, more than one visual indicator and voice broadcaster 9 are respectively installed in the cab of the forklift, which is not shown in the figure.

[0050] Optionally, the rocker-type limiter 3 is a flexible metal sheet structure, which can be made of stainless steel 304.

[0051] In an embodiment, referring to Figure 7 The rocker-type limiter 3 comprises a plate-shaped body 34 and a baffle part 35 arranged at the front end of the plate-shaped body 34.

[0052] In a specific embodiment, the limiting groove 2 is opened at the top surface of the front fork 1 at a front segment of 10 cm. When the goods pallet is not loaded, the baffle part 35 is 1 mm lower than the top surface of the front fork 1, and the rear end of the plate-shaped body 34 is 3 mm higher than the top surface of the front fork 1.

[0053] As the front fork 1 is slowly inserted into the goods pallet 6, when the goods pallet 6 presses down the rear end of the plate-shaped body 34, the baffle part 35 is lifted, at which time the rear end of the plate-shaped body 34 and the baffle part 35 are both pressed against the goods pallet 6 below, the path blocking part 33 blocks the receiving path, the receiver 5 cannot receive the signal emitted by the transmitter 4, the controller 7 controls the red visual indicator 81 to be bright and the green visual indicator 82 to be not bright, and the voice broadcaster 9 broadcasts "please adjust", at which time it indicates that the position of the front fork inserted into the goods pallet 6 is unreasonable and the goods are easy to fall over; when the goods pallet 6 is in position, the path blocking part 33 of the rocker-type limiter 3 pops out of the limiting groove 2, so that the path blocking part 33 is not on the receiving path, i.e. the receiving path is opened, at which time the baffle part 35 blocks the front segment of the goods pallet 6, the controller 7 controls the green visual indicator 82 to be bright and the red visual indicator 81 to be not bright, and the voice broadcaster 9 broadcasts "reasonable position", which can proceed to the next operation.

[0054] The utility model provides a kind of thought and method of preventing goods from dumping of fork truck, the method and approach of the technical scheme of specific implementation are many, above-mentioned are only preferred embodiment of the utility model, it should be pointed out, for the ordinary skilled person in the art, without departing from the principle of the utility model, still can make several improvements and refinements under the premise, these improvements and refinements also should be considered as the protection scope of the utility model. The components not specified in the embodiment can be implemented using existing technology.
