Description

Technical Field

[0001] This application relates to the technical field of forklift protection components, and in particular to a high-strength forklift overhead guard assembly. Background Technology

[0002] Forklifts, as multi-functional machines widely used in railway, highway, construction, hydropower, port and dock, and national defense engineering projects, play a vital role in stacking and moving heavy objects. In particular, the forklift overhead guard, as an important component for protecting driver safety, effectively safeguards the driver in the event of a cargo fall.

[0003] The existing announcement number CN203513188U, entitled "A High-Performance Forklift Overhead Guard Assembly," includes a bracket, a top guard mounted on the bracket, guard plates slidably mounted on two crossbeams of the top guard, a protective frame fixedly mounted between the guard plates, and "U"-shaped grooves with pulleys built into the grooves. Supplemental lights are also provided at each of the four corners of the top guard. The top guard is a quadrilateral structure composed of two parallel crossbeams and two parallel longitudinal beams. This utility model has a simple structure and reasonable design, providing better lighting for operators when driving forklifts, unaffected by external light.

[0004] Regarding the aforementioned technologies, the inventors discovered that most of the protective frames on the aforementioned top guards are fixed by welding, which causes inconvenience to some extent. When the protective frame is damaged due to bearing a lot of weight, replacement requires disassembling the entire top guard assembly or directly replacing the top guard, which is a cumbersome and time-consuming process. Utility Model Content

[0005] To overcome the problem that replacing existing overhead guards requires disassembling the entire overhead guard assembly or directly replacing the entire overhead guard when they are damaged due to bearing heavy loads, which is a cumbersome and time-consuming process, this application provides a high-strength forklift overhead guard assembly.

[0006] The high-strength forklift overhead guard assembly provided in this application adopts the following technical solution: A high-strength forklift overhead guard assembly includes a support component, an assembly component, and a protective component. The support component includes a roof support bracket, the bottom end of which is fixed to the roof of the forklift by locking bolts. Multiple vibration damping components are vertically assembled on the top surface of the roof support bracket, and an assembly component is provided on the top of the multiple vibration damping components. The assembly component includes an assembly frame, which is horizontally fixed to the top of the multiple vibration damping components. Multiple sliding frames are vertically fixed on both vertical end faces of the assembly frame. The protective component includes a roof frame, on both vertical end faces of the roof frame, multiple sliding strips are vertically fixed, and the multiple sliding strips are vertically slidably assembled with the multiple sliding frames on the assembly frame.

[0007] By adopting the above technical solution, the roof support in the support component is fixed to the forklift roof with locking bolts, bearing the main support function and ensuring the stability of the overhead guard. Simultaneously, the vibration damping component is fixed to the top surface of the roof support and connected to the assembly at the top, effectively absorbing and dispersing the impact force generated by falling objects during forklift operation, improving overall stability and safety. The assembly frame in the assembly component connects the tops of each vibration damping component through a fixed method, making the overhead guard structure more compact and robust, and providing a stable guide surface for the protective components through the sliding frames on both sides. The roof frame in the protective component slides within the sliding frames via sliders, automatically adjusting its position to adapt to different forklift roof heights, ensuring effective protection of the driver's head under various operating conditions, achieving a multi-functional and highly reliable forklift overhead guard system. The roof support provides basic support, the vibration damping component absorbs vibration, the assembly provides uniformity and guidance, and the protective components offer flexible and stable protection, collectively ensuring all-round safety of the forklift during driving and operation.

[0008] Optionally, the outer sides of the assembly frame are horizontally slidably inserted with assembly brackets, and the vertical end faces of both sides of the roof frame are horizontally provided with insertion holes, which are slidably inserted with the assembly brackets.

[0009] By adopting the above technical solution, the assembly frame is used to fix and support the overall structure. The horizontally sliding assembly brackets on both sides can be easily adjusted in position, making the device more flexible. The insertion holes on the vertical end faces of the roof frame ensure reliable insertion of the assembly brackets and improve the stability of the overall structure.

[0010] Optionally, assembly springs are horizontally fitted on the outside of the assembly bracket, and the two ends of the assembly springs are fixed to the outer walls of the assembly bracket and the assembly frame, respectively.

[0011] By adopting the above technical solution, the assembly spring is sleeved on the outside of the assembly bracket, with both ends fixed to the assembly bracket and the assembly frame respectively. This not only compensates for minor gaps caused by wear on the contact surfaces or uneven force, but also provides a certain degree of elastic buffering when fixed in position, enhancing the adaptability and durability of the structure. It achieves rapid and flexible assembly and efficient fixing of the protective components, facilitating installation and disassembly, making it easy to replace the protective components later, and ensuring good stability and durability of the overall structure during use.

[0012] Optionally, a roof panel is horizontally installed on the top surface of the roof rack, and multiple reinforcing ridges are horizontally fixed on the roof panel.

[0013] By adopting the above technical solution, the roof rack, as the main supporting structure of the vehicle's roof, provides a stable load-bearing platform through the horizontally installed roof panel above it. Multiple reinforcing ribs are horizontally fixed to the roof panel, effectively improving the roof's load-bearing capacity and structural strength, thus increasing the vehicle's safety when loaded with heavy objects.

[0014] Optionally, multiple crumple bars are fixed horizontally and vertically on both sides of the roof panel, and the bottom ends of the multiple crumple bars are fixed to the top surface of the roof frame.

[0015] By adopting the above technical solution, the horizontally and vertically fixed crumple bars on both sides of the roof panel can crumple along a predetermined path during a collision, effectively absorbing impact energy and protecting passenger safety. When the vehicle encounters a collision while in motion, the reinforcing ribs on the roof panel will initially absorb the impact force, while the crumple bars begin to compress and deform layer by layer along the predetermined path, absorbing and dispersing the impact energy to protect the safety of the passengers inside. The roof frame, as the overall framework, ensures the stability and integrity of the structure during the crumple process, jointly ensuring that the vehicle can effectively reduce injury to passengers when it is hit.

[0016] Optionally, the vibration damping component includes a rubber sleeve seat, with grooves at both the upper and lower ends of the rubber sleeve seat, and studs inserted into both the upper and lower grooves of the rubber sleeve seat.

[0017] By adopting the above technical solution, the rubber cylinder seat, as the core part of the vibration damping component, uses studs installed in the grooves at its upper and lower ends to fix the entire vibration damping device between the roof bracket and the assembly frame, thereby ensuring the stability of the vibration damping device.

[0018] Optionally, a damping rod is vertically inserted inside the rubber sleeve, and the two ends of the damping rod are respectively fixed to the upper and lower studs of the rubber sleeve. A damping spring is vertically sleeved outside the damping rod, and the two ends of the damping spring are respectively fixed to the upper and lower studs of the rubber sleeve.

[0019] By adopting the above technical solution, the damping rod is vertically inserted into the rubber sleeve and fixed to the upper and lower studs, providing a certain internal limit while increasing the rigidity and stability of the system. The damping spring is tightly fitted around the damping rod and is fixed to the upper and lower studs of the rubber sleeve to achieve constraint between the two. When subjected to vibration or impact, it can generate elastic force to absorb vibration energy, effectively reducing the vibration intensity transmitted from the outside to the vehicle interior, significantly improving the vehicle's driving comfort and safety. When the vehicle encounters uneven road surfaces or is impacted by other external forces, the damping spring and damping rod work together, using their elasticity and damping characteristics to absorb and dissipate a large amount of vibration energy, greatly reducing the vibration transmitted to the vehicle interior, thereby ensuring passenger comfort and vehicle structural safety.

[0020] Optionally, the top surface of the roof bracket is vertically provided with assembly screw holes, and the bottom surface of the assembly insert frame is provided with connecting screw holes. The studs at the upper and lower ends of the rubber sleeve are respectively threaded into the assembly screw holes of the roof bracket and the connecting screw holes of the assembly insert frame.

[0021] By adopting the above technical solution, the studs at the upper and lower ends of the rubber cylinder seat are respectively threaded into the assembly screw holes of the roof bracket and the connecting screw holes of the assembly insert frame, for connecting the assembly parts and the support parts.

[0022] In summary, this application includes at least one of the following beneficial technical effects: the roof bracket, as a key component of the support structure, is fixed to the roof frame of the forklift by a bottom locking bolt, thereby fixing the position of the support structure; the rubber sleeve seat and assembly screw hole are used to install multiple vibration damping components, which are threadedly assembled between the roof bracket and the assembly to provide vibration damping; the assembly pin and assembly spring enable quick assembly and disassembly between the assembly and the protective component. Specifically, after compressing the assembly spring to deform it, the roof frame is inserted into the assembly pin frame, and when released, the restoring force of the assembly spring causes the assembly pin to automatically insert into the pin hole of the roof frame, achieving the function of quick assembly and disassembly. The support structure is fixed to the roof frame by bolts, providing initial support stability; the vibration damping components enhance the overall vibration damping effect; and the assembly and protective component are quickly and conveniently installed and disassembled by spring force.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a high-strength forklift overhead guard assembly. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A high-strength forklift overhead guard assembly includes a support component 1, an assembly component 2, and a protective component 3. The support component 1 includes a roof support 11, the bottom end of which is fixed to the roof of the forklift by locking bolts 111. Multiple vibration damping components 13 are vertically assembled on the top surface of the roof support 11, and the top of the multiple vibration damping components 13 is provided with an assembly component 2. The assembly component 2 includes an assembly frame 21, which is horizontally fixed to the top of the multiple vibration damping components 13. Multiple sliding frames 22 are vertically fixed on both vertical end faces of the assembly frame 21. The protective component 3 includes a roof frame 31, and multiple sliding strips 32 are vertically fixed on both vertical end faces of the roof frame 31. The multiple sliding strips 32 are vertically slidably assembled with the multiple sliding frames 22 on the assembly frame 21.

[0027] By adopting the above technical solution, the roof support 11 in the support component 1 is fixed to the roof of the forklift by locking bolts 111, bearing the main support function and ensuring the stability of the overhead guard. Simultaneously, the vibration damper 13 is fixed to the top surface of the roof support 11 and connected to the assembly component 2 at the top, effectively absorbing and dispersing the impact force generated by falling objects during forklift operation, improving overall stability and safety. The assembly frame 21 in the assembly component 2 connects the tops of each vibration damper 13 by a fixed method, making the overhead guard structure more compact and robust, and provides a stable guide surface for the protective component 3 through the sliding frames 22 on both sides. The roof frame 31 in the protective component 3 slides within the sliding frame 22 via a sliding bar 32, automatically adjusting its position to adapt to different forklift heights, ensuring effective protection of the driver's head under various operating conditions, thus realizing a multi-functional and highly reliable forklift overhead guard system. The roof support 11 provides basic support, the vibration damper 13 absorbs vibration, the assembly component 2 provides uniformity and guidance, and the protective component 3 provides flexible and stable protection, collectively ensuring all-round safety of the forklift during driving and operation.

[0028] Reference Figure 3 and Figure 5The assembly frame 21 has horizontally sliding insertion brackets 23 on both sides of its outer surface. The roof frame 31 has horizontally opening holes 33 on both vertical end faces, which are slidably inserted into the assembly brackets 23. The assembly frame 21 is used to fix and support the overall structure. The horizontally sliding insertion of the assembly brackets 23 on both sides allows for easy adjustment of their position, making the device more flexible. The insertion holes 33 on both vertical end faces of the roof frame 31 ensure reliable insertion of the assembly brackets 23 and improve the overall structural stability. Assembly springs 24 are horizontally fitted on the outside of each assembly bracket 23, with both ends fixed to the outer walls of the assembly brackets 23 and the assembly frame 21, respectively. The assembly springs 24, fitted on the outside of the assembly brackets 23 and fixed to both ends of the assembly brackets 23 and the assembly frame 21, not only compensate for minor gaps caused by wear on the contact surfaces or uneven force, but also provide a certain degree of elastic buffering when fixed in position, enhancing the adaptability and durability of the structure. The system enables quick and flexible assembly and efficient fixing of the protective component 3, which not only facilitates installation and disassembly and makes it easy to replace the protective component 3 on the assembly component 2 later, but also ensures that the overall structure has good stability and durability during use.

[0029] Reference Figure 5 The roof rack 31 has horizontally mounted roof panels 34 on its top surface, with multiple reinforcing ribs 35 horizontally fixed to each roof panel 34. As the main supporting structure for the vehicle roof, the roof rack 31 provides a stable load-bearing platform through the horizontally mounted roof panels 34. The horizontally fixed reinforcing ribs 35 on the roof panels 34 effectively enhance the load-bearing capacity and structural strength of the roof, increasing vehicle safety when loaded with heavy loads. Multiple crumple bars 36 are horizontally and vertically fixed to both sides of the roof panels 34, with the bottom ends of the crumple bars 36 fixed to the top surface of the roof rack 31. The horizontally and vertically fixed crumple bars 36 on both sides of the roof panels 34 can crumple along a predetermined path in the event of a collision, effectively absorbing impact energy and protecting passenger safety. When a vehicle is involved in a collision, the reinforcing ribs 35 on the roof panel 34 will first absorb the impact force, while the crumple bars 36 will begin to compress and deform layer by layer along a predetermined path to absorb and disperse the impact energy and protect the safety of the passengers inside. The roof frame 31, as the overall frame, ensures the stability and integrity of the structure during the crumple process, and together they ensure that the vehicle can effectively reduce the injury to the passengers when it is hit.

[0030] Reference Figure 3 and Figure 4The damping component 13 includes a rubber cylinder seat 131. Grooves are formed at both the upper and lower ends of the rubber cylinder seat 131, and studs 132 are inserted into both grooves. As the core component of the damping component, the rubber cylinder seat 131, through the studs 132 in its grooves, secures the entire damping device between the roof support 11 and the assembly frame 21, ensuring the stability of the damping device. A damping rod 133 is vertically inserted inside the rubber cylinder seat 131, with both ends fixed to the upper and lower studs 132. A damping spring 134 is vertically sleeved outside the damping rod 133, with both ends fixed to the upper and lower studs 132. The vertical insertion of the damping rod 133 into the rubber cylinder seat 131 and its fixation to the studs 132 provides internal restraint and increases the rigidity and stability of the system. The damping spring 134 is tightly fitted around the damping rod 133 and is constrained by the upper and lower studs 132 fixed to the rubber sleeve seat 131. When subjected to vibration or impact, it can generate elastic force to absorb vibration energy, effectively reducing the vibration intensity transmitted from the outside to the vehicle interior, significantly improving the vehicle's driving comfort and safety. The overall working principle is that when the vehicle encounters uneven road surfaces or is impacted by other external forces, the damping spring 134 and the damping rod 133 work together, using their elasticity and damping characteristics to absorb and dissipate a large amount of vibration energy, greatly reducing the vibration transmitted to the vehicle interior, thereby ensuring passenger comfort and vehicle structural safety. The roof support 11 has vertically formed assembly screw holes 12 on its top surface, and the assembly frame 21 has connected screw holes 25 on its bottom surface. The studs 132 at both ends of the rubber sleeve seat 131 are threaded into the assembly screw holes 12 of the roof support 11 and the connected screw holes 25 of the assembly frame 21, respectively. The studs 132 at the upper and lower ends of the rubber sleeve seat 131 are respectively threaded into the assembly screw holes 12 of the roof bracket 11 and the connecting screw holes 25 of the assembly insert frame 21, for connecting the assembly component 2 and the support component 1.

[0031] The implementation principle of a high-strength forklift overhead guard assembly in this application embodiment is as follows: First, the roof bracket 11 in the support component 1 is fixed to the roof frame of the forklift using the bottom locking bolt 111. Then, the bottom studs 132 of the rubber cylinder seats 131 in the multiple vibration damping components 13 are threaded into the assembly screw holes 12 of the roof bracket 11. Then, the top studs 132 of the multiple vibration damping components 13 are threaded into the connecting screw holes 25 of the assembly insert frame 21 of the assembly component 2, thus completing the fixed assembly of the support component 1 and the assembly component 2. Then, pull the assembly brackets 23 on both sides of the assembly frame 21 to slide outwards and pull out the assembly frame 21, compress the assembly spring 24 to deform, and then insert the roof rack 31 in the protective component 3 into the interior of the assembly frame 21. Release the assembly bracket 23 and, under the deformation force of the assembly spring 24, insert the pin on the assembly bracket 23 into the insertion hole 33 of the roof rack 31, thus completing the quick-release assembly of the protective component 3 and the assembly component 2.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
