Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to an early warning device for preventing forklift collision. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that are used for loading and unloading, stacking and short-distance transportation of palletized goods. The International Organization for Standardization ISO / TC110 calls them industrial vehicles. They are often used for the transportation of large objects in warehouses and are usually powered by fuel engines or batteries.

[0003] When a forklift is carrying goods, the fork arm and fork plate at the front end of the forklift must first cooperate with each other to fork and lift the goods, and then drive the forklift to the designated location. When the forklift lifts the goods in front, the forklift driver's vision is blocked, and because the front end of the fork arm is relatively sharp, if a collision occurs during driving, it may cause very serious consequences. The warning device for preventing forklift collisions under the existing technology generally adopts monitoring radar and signal device control. Although this method has a significant warning effect, it has a high cost and is not suitable for most forklift users. For this reason, we propose an early warning device for preventing forklift collisions. Utility Model Content

[0004] A technical problem to be solved by the present application is: how to conveniently and simply prevent forklift collisions and issue early warnings.

[0005] To achieve the above object, the utility model provides the following technical solution: an early warning device for preventing forklift collision, comprising a forklift body and a combined fork arm arranged at one end of the forklift body, and also comprising:

[0006] A movement control mechanism, wherein the movement control mechanism is arranged above the combined fork arm;

[0007] The early warning protection mechanism is arranged near one end of the combined fork arm, and the ejection and retraction of the early warning protection mechanism are controlled by the mobile control mechanism.

[0008] The measures to further optimize this technical solution are:

[0009] As an improvement, the combined fork arm comprises a fork plate, a side surface of which is fixedly provided with a symmetrically arranged fork rod, and the fork plate is slidably arranged on a side surface of the forklift body.

[0010] As an improvement, the movement control mechanism includes a moving block, one end of which is provided with a bellows, a connecting pipe is fixedly provided at the lower end of the fork rod, and one end of the connecting pipe is provided with a relay bin.

[0011] As an improvement, one end of the connecting pipe passes through the fork rod and communicates with the interior of the bellows, and the other end of the connecting pipe communicates with the relay chamber.

[0012] As an improvement, the early warning protection mechanism includes a telescopic tube, a movable pile is fixedly provided at one end of the telescopic tube, a protective soft board is provided on the movable pile, an airbag is provided at one end of the protective soft board, and an alarm is provided at one end of the airbag.

[0013] As an improvement, one end of the telescopic tube passes through the relay bin and is connected to the connecting pipe, the movable pile is slidably arranged on one side of the fork rod, one side of the protective soft board is coated with magnetic powder, and the airbag is connected to the alarm.

[0014] As an improvement, a symmetrically arranged limiting frame is provided at one end of the fork rod, a connecting shaft is fixedly provided on the opposite side of the limiting frame, an outer wall of the connecting shaft is sleeved with a telescopic spring, the other end of the connecting shaft is slidably provided on the side wall of the fork rod, and the other end of the telescopic spring is fixedly provided on the side wall of the fork rod.

[0015] The utility model has at least the following beneficial effects:

[0016] 1. By setting up a mobile control mechanism and a warning protection mechanism, when the goods are placed on the fork rod, the moving block drives the bellows to contract, pushes the telescopic tube forward, and makes the protective soft plate and the airbag move forward and unfold. When encountering a collision, the airbag is compressed and the alarm sounds an alarm. At the same time, the protective soft plate protects the colliding object from being pierced by the sharp end of the fork rod, so as to quickly and conveniently realize the early warning and protection against forklift collision.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] See also Figure 1-5 The utility model provides a technical solution for an early warning device for preventing forklift collisions: an early warning device for preventing forklift collisions, comprising a forklift body 1 and a combined fork arm 2 arranged at one end of the forklift body 1, and also comprising: a mobile control mechanism 3 arranged above the combined fork arm 2; an early warning protection mechanism 4 arranged near one end of the combined fork arm 2, and the early warning protection mechanism 4 is controlled to pop out and retract by the mobile control mechanism 3.

[0029] The combined fork arm 2 includes a fork plate 201, and a fork rod 202 symmetrically arranged is fixedly arranged on one side of the fork plate 201. The fork plate 201 is slidably arranged on one side of the forklift body 1. The fork plate 201 and the fork rod 202 are both inherent facilities on the forklift body 1. This is the prior art and will not be elaborated on here.

[0030] The mobile control mechanism 3 includes a moving block 301, which is slidably set on the upper end surface of the fork rod 202. The upper end surface of the fork rod 202 is provided with a sliding groove compatible with the moving block 301. A bellows 302 is set at one end of the moving block 301. The bellows 302 can be compressed repeatedly and has a certain elasticity. It will automatically reset when the resistance is lost. A connecting pipe 303 is fixedly set at the lower end of the fork rod 202. A relay chamber 304 is set at one end of the connecting pipe 303. The connecting pipe 303 and the relay chamber 304 are set to transfer the gas in the bellows 302 to the telescopic tube 401.

[0031] One end of the connecting tube 303 passes through the fork rod 202 and communicates with the interior of the bellows 302 , and the other end of the connecting tube 303 communicates with the relay chamber 304 .

[0032] The early warning protection mechanism 4 includes a telescopic tube 401, one end of which is fixedly arranged on the relay bin 304, and the telescopic tube 401 is arranged in two sections. A movable pile 402 is fixedly arranged on one end of the telescopic tube 401, and a protective soft board 403 is arranged on the movable pile 402. An airbag 404 is arranged at one end of the protective soft board 403, and an alarm 405 is arranged at one end of the airbag 404.

[0033] One end of the telescopic tube 401 passes through the relay bin 304 and is connected to the connecting tube 303. The movable pile 402 is slidably set on one side of the fork rod 202. One side of the protective soft board 403 is coated with magnetic powder, and the fork rod 202 is made of steel. Therefore, one side of the protective soft board 403 will always stick to the side of the fork rod 202. The airbag 404 is connected to the alarm 405. When the airbag 404 is compressed, the gas inside it will be filled into the alarm 405. The alarm 405 is a whistle type setting, and a harsh sound alarm will occur when filled with gas.

[0034] When the forklift body 1 starts to carry goods, the goods are first pushed onto the fork rod 202. At this time, the goods will synchronously push the moving block 301 to move to one end. At this time, the bellows 302 is compressed, and the air in the bellows 302 passes through the connecting pipe 303 and the relay bin 304, thereby pushing one end of the telescopic tube 401 to move. The movement of one end of the telescopic tube 401 will drive the moving pile 402 to start sliding. When the moving pile 402 slides to the end of the fork rod 202, the air bag 404 loses the resistance of the bottom surface of the fork rod 202 and is released and popped out. At the same time, it will drive the protective soft board 403 to pop out. The side of the rod 202 that is in contact with the rod is coated with magnetic powder, so one side of the rod will always be adsorbed on the side of the fork rod 202. At this time, the rubber surface of the protective soft board 403 will pop out and stick to the outer wall of the fork rod 202. If a collision occurs, the sharp part of the fork rod 202 will be wrapped by the protective soft board 403, which will buffer most of the impact force and will not cause the fork rod 202 to pierce the object. At the same time, when a collision occurs, the object will first contact the airbag 404, and the airbag 404 will be squeezed, and the gas inside it will quickly flow to the alarm 405. The alarm 405 is a whistle type setting, so it will emit a harsh sound to alarm.

[0035] Embodiment 2:

[0036] See also Figure 1-7 The utility model provides another technical solution of the combined fork arm 2, which is different from the first embodiment, including a symmetrically arranged limiting frame 305 at one end of the fork rod 202, a connecting shaft 306 is fixedly arranged on the opposite side of the limiting frame 305, and a telescopic spring 307 is sleeved on the outer wall of the connecting shaft 306. The other end of the connecting shaft 306 is slidably arranged on the side wall of the fork rod 202, and the other end of the telescopic spring 307 is fixedly arranged on the side wall of the fork rod 202. The limiting frame 305 is provided to limit the resetting of the moving block 301.

[0037] With such an arrangement, when there is no cargo piled on the fork bar 202, the early warning protection mechanism 4 can be manually unfolded to push the moving block 301 to the limiting frame 305. The limiting frame 305 will be constantly tightened due to the telescopic spring 307, which will resist the moving block 301 and prevent it from resetting.
