Description

Technical Field

[0001] This utility model belongs to the field of forklift technology, and in particular relates to a forklift cab with a protective structure. Background Technology

[0002] Forklifts are industrial handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. They are widely used in various sectors of the national economy, such as stations, ports, airports, factories, and warehouses. Moreover, with the rapid development of China's economy, most enterprises have moved away from manual handling of materials and replaced it with mechanized handling mainly using forklifts.

[0003] For example, patent application CN202122573075.7 describes a highly protective forklift cab, belonging to the technical field of forklift equipment. Its key technical features include: a top guard frame comprising a frame, a pair of front pillars, and a pair of rear pillars, with the front and rear pillars spaced apart on both sides of the vehicle body width; a side door positioned between the front and rear pillars and movably connected to the top guard frame; a front deflector assembly detachably connected between the two front pillars; a rear deflector assembly detachably connected between the two rear pillars; and a top assembly detachably connected to the top guard frame. The front and rear pillars are all constructed of reinforced steel tubing. This application provides a forklift cab that increases structural strength, improves safety, and extends the service life of the forklift cab.

[0004] Existing technologies increase the structural strength of the forklift cab through features such as overhead guards and side doors, but certain shortcomings still exist in overall use: First, the main structural components of the forklift cab are made of special-shaped steel pipe profiles, which gives the forklift cab a certain effect of preventing falling objects and preventing rollover. However, the strength of the top frame of the forklift cab is still not high enough. If the goods collapse, the falling goods may directly penetrate the roof and then hit the driver's head, causing serious injury. At the same time, the roof lacks a buffer space. Even if the top frame is not directly penetrated by the goods, the huge impact force may deform it and intrude into the cab space, resulting in low safety performance. Secondly, the windshield of a forklift is relatively fragile and cannot withstand repeated impacts. When goods fall, it is easy to crack or shatter, and the goods may crash into the cab, causing injury to the driver and seriously affecting the safety of the driver inside the vehicle. Utility Model Content

[0005] In order to overcome the technical problems of the limited strength of the top frame structure of the cab in the prior art, which makes it difficult to completely resist the impact of goods falling from a height and poses a risk of being smashed, and the lack of effective buffer space in the structural design, even if the roof is not directly smashed, the huge impact force can easily cause the top guard to deform and intrude into the cab, as well as the relatively fragile windshield when facing the impact of goods, which is easily cracked or broken, this utility model provides a forklift cab with a protective structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forklift cab with a protective structure, comprising a rear beam, a top beam, and a front beam, wherein the rear beam, top beam, and front beam form the cab frame; a baffle is elastically connected to the top of the top beam; a pressure sensor is fixedly installed at the bottom of the baffle; a connecting rod is slidably installed inside the baffle; a connector is fixedly installed at the end of the connecting rod; a protective plate is rotatably installed at the end of the connector; a first limiting block is fixedly installed at the middle of the end of the protective plate near the connecting rod; and a second limiting block is fixedly installed above the first limiting block at the end of the connecting rod near the protective plate.

[0007] Optionally, an electric telescopic rod is fixedly installed on the side of the baffle away from the front beam, and the output end of the electric telescopic rod is fixed to the connecting rod.

[0008] Optionally, a rubber sheet is fixedly installed on the upper surface of the protective plate.

[0009] Optionally, an arc-shaped slider is fixedly installed on the lower surface of the connecting rod, and the slider abuts against the receiving cavity.

[0010] Optionally, multiple vertical reinforcing ribs and multiple horizontal reinforcing ribs are fixedly installed between the opposite sides of the top beam, and the vertical and horizontal reinforcing ribs are generally in a mesh shape.

[0011] Optionally, a reinforcing beam is fixedly installed between the top beam and the front beam.

[0012] Optionally, damping sleeves are fixedly installed at the four corners of the top beam, and springs are fixedly installed inside the damping sleeves. Telescopic columns are slidably installed at the top of the inner cavity of the damping sleeves and at the top of the springs. The tops of the four telescopic columns are fixed to the baffles.

[0013] Optionally, the top of the baffle is provided with an arc-shaped protrusion.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model, through the setting of connecting rod, protective plate, first limiting block, second limiting block and rubber plate, can push out the protective plate and rotate downward when the goods fall, so as to protect the windshield and prevent the falling goods from impacting the windshield multiple times, thus preventing it from breaking and the goods from entering the driver's seat and causing injury to the driver, thereby effectively improving safety.

[0015] (2) This utility model, through the setting of damping sleeve, spring, telescopic column, baffle and protrusion, can protect the top of the cab when the cargo falls, and at the same time can reduce the shock of the cargo, reduce the damage to the cargo, and prevent the cargo from breaking through the top of the cab, thus greatly improving the protection effect.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] refer to Figure 1A forklift cab with a protective structure includes a rear beam 10, a top beam 11, and a front beam 12. The rear beam 10, top beam 11, and front beam 12 form the cab frame. A reinforcing beam 17 is fixedly installed between the top beam 11 and the front beam 12 to enhance the stability between them, thereby improving safety. A windshield is fixedly installed inside the front beam 12.

[0020] Further reference Figure 1 and Figure 5 The top beam 11 is shaped like a square. Multiple vertical reinforcing ribs 13 and multiple horizontal reinforcing ribs 14 are fixedly installed between the opposite sides of the top beam 11. The vertical reinforcing ribs 13 and the horizontal reinforcing ribs 14 are in a mesh-like pattern, which greatly enhances the overall strength of the top beam 11, thereby improving its impact resistance and enabling it to withstand multiple impacts when goods collapse, further improving safety.

[0021] Further reference Figure 1 , Figure 2 , Figure 3 and Figure 7 The inner cavity of the top beam 11 is fixedly fitted with a cover 15 on the upper surface of the vertical reinforcing ribs 13 and the horizontal reinforcing ribs 14 to seal the top beam 11, which is used to seal and isolate external noise during driving. The inner cavity of the top beam 11 is fixedly fitted with a sound insulation cotton 16 on the lower surface of the vertical reinforcing ribs 13 and the horizontal reinforcing ribs 14 to further isolate noise and create a comfortable driving environment.

[0022] Further reference Figure 1 , Figure 5 and Figure 6 Damping sleeves 18 are fixedly installed at the four corners of the rear beam 10. Springs 19 are fixedly installed inside the damping sleeves 18. Telescopic columns 20 are slidably installed at the top of the inner cavity of the damping sleeves 18 and the top of the springs 19. Baffles 21 are fixedly installed at the top of the four telescopic columns 20. If cargo collapses, the cargo will hit the upper surface of the baffles 21. Then, the telescopic columns 20 will compress the springs 19 to deform and buffer the baffles 21. After the damping sleeves 18 absorb the shock, the impact force of the cargo is reduced, and the top of the cab is protected to prevent it from collapsing or penetrating and causing injury to the driver inside, thereby improving the driver's safety.

[0023] Further reference Figure 1 The top of the baffle 21 is provided with an arc-shaped protrusion 22, which can guide the goods to both sides when they hit the surface of the baffle 21, so that the goods roll to both sides and prevent the goods from hitting the windshield again, thus avoiding breaking it and improving the safety of the windshield.

[0024] Further reference Figure 1 and Figure 3The baffle 21 has a storage cavity 25 inside, and a connecting rod 26 is slidably installed inside the storage cavity 25. A pressure sensor 23 is fixedly installed on the lower surface of the baffle 21. The pressure sensor 23 is existing technology and will not be described in detail in this solution. An electric telescopic rod 24 is fixedly installed on the side of the baffle 21 away from the front beam 12. The output end of the electric telescopic rod 24 is fixed to one end of the connecting rod 26. When the collapsed goods hit the baffle 21, the pressure sensor 23 detects the pressure, and the electric telescopic rod 24 starts to work to push the connecting rod 26 forward, which facilitates the subsequent protection work.

[0025] Further reference Figure 3 and Figure 4 A connector 27 is fixedly installed at the end of the connecting rod 26. A protective plate 28 is rotatably installed at the end of the connector 27. A first limiting block 29 is fixedly installed at the middle of the end of the protective plate 28 near the connecting rod 26. A second limiting block 30 is fixedly installed above the first limiting block 29 at the end of the connecting rod 26 near the protective plate 28. When the connecting rod 26 is pushed out by the electric telescopic rod 24, it is pushed out together with the protective plate 28. When the protective plate 28 is pushed out of the outside of the baffle 21, due to the rotatable connection between the protective plate 28 and the connector 27, the protective plate 28 is able to rotate outwards. When plate 28 rotates downwards, the first limiting block 29 abuts against the lower surface of the second limiting block 30, limiting the first limiting block 29 and stopping the rotation of the protective plate 28. This causes the protective plate 28 to tilt downwards, protecting the windshield from multiple impacts from cargo and preventing it from shattering, thus improving driver safety. After protection is completed, the electric telescopic rod 24 can be controlled to pull back the protective plate 28, storing it inside the baffle 21. This prevents the protective plate 28 from obstructing the driver's view during use and improves its effectiveness.

[0026] Further reference Figure 4 A rubber plate 31 is fixedly installed on the upper surface of the protective plate 28, so that when the goods hit the protective plate 28, the protective plate 28 and the goods are shock-absorbing, which not only prevents damage to the goods, but also absorbs the shock of the protective plate 28 and improves the service life of the protective plate 28.

[0027] Further reference Figure 4 A slider 32 is fixedly installed on the lower surface of the connecting rod 26. The bottom of the slider 32 is arc-shaped and abuts against the storage cavity 25. During use, it can reduce the friction between the connecting rod 26 and the storage cavity 25, facilitate its sliding, reduce its wear, and thus improve its service life.

[0028] Finally, it should be noted that the connection and fixing of each part of the forklift cab with protective structure of this utility model can be achieved by conventional mechanical connection structure, and the control system and connection method required between multiple electrical components and drive components can also be achieved by conventional means and can be equipped with corresponding sensors and detectors. As long as it can achieve its beneficial effect or the specific actions in the above-mentioned work, it can be implemented.
