[0002] A forklift is a type of industrial handling vehicle and is usually widely used in ports, stations, airports, freight yards, factory workshops, warehouses, distribution centers, etc. It is an essential equipment in pallet transportation and container transportation. Among forklifts, there is a hand-pushed electric forklift, which is a small logistics transportation equipment mainly used for short-distance cargo transportation.
[0003] Currently, for related forklifts, due to the lack of two anti-collision mechanisms, namely structural anti-collision and electronic prompt anti-collision, and only electronic prompt anti-collision is carried out, it is impossible to avoid the collision caused by the wrong operation of the staff, resulting in the goods falling from the front of the device.

Specific implementation manners
[0024] The following further describes the present application in detail with reference to the Figures 1-5 drawings.
[0025] The embodiment of the present application discloses an anti-collision forklift. Refer to Figures 1-5, an anti-collision forklift, comprising a limit plate 2, an ultrasonic sensor 3 and a forklift body 9. Positioning rods 8 are movably installed at both ends of the forklift body 9. A movable plate 15 is embedded in the bottom of the forklift body 9. One side of the movable plate 15 is fixedly connected to a movable member 5. Threaded fixing rods 7 are movably installed at both ends of the movable member 5. A card hole 202 is provided inside the limit plate 2 at the closer ends of the threaded fixing rods 7, and the threaded fixing rods 7 are threadedly connected to the card hole 202. A limit plate 2 is movably installed inside the movable member 5. A guardrail 1 is movably installed at the closer ends of the limit plates 2. Insert the fork part of the forklift body 9 under the pallet of the goods, and then control the forklift body 9 to lift the pallet and the goods. The forklift body 9 is a hand-pushed electric forklift, which is common general knowledge, so no more details will be given. Push the forklift body 9 to transport the goods. Pull out the movable plate 15 and the limit plate 2 from the bottom of the forklift body 9. Pull up the limit plate 2 upwards, so that the limit plate 2 is rotated and adjusted to a vertical state of 90° through the movable member 5. The threaded magnetic attraction rod 701 is a rectangular rod body. Screw the threaded fixing rod 7 into the inside of the threaded magnetic attraction rod 701 to connect and fix the threaded fixing rod 7 to the threaded magnetic attraction rod 701. Then insert the threaded magnetic attraction rod 701 between the movable member 5 and the limit plate 2 into the card hole 202, so that the threaded magnetic attraction rod 701 adsorbs to the limit plate 2 made of metal material, and the angle of the limit plate 2 can be limited. Finally, unscrew and disassemble the threaded fixing rod 7 to prevent the threaded fixing rod 7 from affecting the sliding of the limit plate 2 into the forklift body 9 when the limit plate 2 is retracted. Insert the guardrail 1 inside the limit plate 2. Silicone rubber is provided on the peripheries of the guardrail 1 and the limit plate 2, which can slow down and absorb the external force impact received by the device, and can form a protection at the front end of the device and limit the goods, preventing the front end of the goods from being hit and falling from the front end of the device. When the limit plate 2 is not in use, rotate and adjust the limit plate 2 to make it parallel to the movable plate 15, and then insert the movable plate 15 and the limit plate 2 into the forklift body 9. Screw the positioning rod 8 between the forklift body 9 and the limit plate 2, and the limit plate 2 can be fixed to the forklift body 9, so that the limit plate 2 will not affect the normal insertion of the forklift into the external pallet. An ultrasonic sensor 3 is fixedly connected to the surface of one side of the limit plate 2. An alarm 4 is fixedly connected to one side of the limit plate 2 at one end of the ultrasonic sensor 3. A reminder 12 is fixedly connected to the top of the forklift body 9. A connecting rod 10 is fixedly connected to one side of the forklift body 9. A controller 11 is fixedly connected to the top of the connecting rod 10. The ultrasonic sensor 3 uses the principle of ultrasonic wave emission and alloy reception of reflected signals to detect the objects in front of the device. When an object is detected to be relatively close to the device, the alarm 4 is controlled by the controller 11 to emit an alarm sound forward, and the reminder 12 is controlled to emit a reminder voice to remind the user that there is an obstacle in front, realizing anti-collision reminder, so that the staff can still judge whether there is an obstacle in front when the field of vision in the due front is blocked, preventing the device from colliding with the obstacle in front. The alarm 4 and the reminder 12 are common sound and light alarms and voice players.All of them are common general knowledge, so no further elaboration will be made. The ultrasonic sensor 3, the alarm 4, and the reminder 12 are all powered by the power supply supporting the forklift body 9, and the wire connections between the alarm 4 and the reminder 12 and the forklift body 9 are routed from the bottom of the movable plate 15, which will not affect the normal use of the device.
[0026] Refer to Figure 1 , inside the limiting plates 2 at both ends of the guardrail 1, there are limiting grooves 201, and the guardrail 1 is fitted with the limiting grooves 201. By inserting the guardrail 1 into the inside of the limiting grooves 201, the guardrail 1 can be installed between the two limiting plates 2. The periphery of the guardrail 1 is provided with silicone rubber.
[0027] Refer to Figure 1 , at both ends inside the limiting plates 2 and the movable plate 15, there are bolt holes 6, and the positioning rods 8 are threadedly connected with the bolt holes 6. By screwing the positioning rods 8 into the inside of the bolt holes 6, the friction force between the limiting plates 2 and the movable plate 15 and the forklift body 9 is increased, realizing the fixation of the limiting plates 2 and the movable plate 15 to the forklift body 9.
[0028] Refer to Figure 3 , the bottom of the forklift body 9 is fixedly connected with movable wheel frames 14, and there are two groups of movable wheel frames 14. The forklift body 9 can be supported through the movable wheel frames 14, and the contact area and friction force between the forklift body 9 and the ground are reduced, enabling the staff to push the device to move.
[0029] Refer to Figure 3 , inside the forklift body 9, there is a fixed groove 13, and the movable plate 15 is fitted with the fixed groove 13. The movable plate 15 can move inside the fixed groove 13, enabling the movable plate 15 to freely adjust horizontally left and right.
[0030] The implementation principle of an anti-collision forklift in an embodiment of the present application is as follows: By placing the goods on the top of the forklift body 9, the forklift body 9 is used to lift the goods, and the forklift body 9 is pushed to transport the goods. The movable plate 15 and the limiting plates 2 are pulled out from the bottom of the forklift body 9, the limiting plates 2 are pulled upward to a vertical state and fixed, and then the guardrail 1 is inserted into the inside of the limiting plates 2. The cooperation between the guardrail 1 and the limiting plates 2 can slow down and absorb the external force impact received by the device, and can also limit the goods to prevent the front end of the goods from being hit and falling from the front end of the device. And when the ultrasonic sensor 3 detects that the object in front of the device is relatively close to the device, the controller 11 controls the alarm 4 and the reminder 12 to give a reminder, realizing anti-collision reminder.
