Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a modular forklift overhead guard. Background Technology

[0002] As a core component of industrial vehicle safety protection, forklift overhead guards are designed to provide operators with a rigid protective barrier against falling objects from above, while also taking into account impact resistance in rollover situations.

[0003] Traditional overhead guards are generally manufactured using an integral welded structure, forming a rigid frame by welding steel or pipes. While this process ensures structural strength, it carries the risk of localized material embrittlement due to welding thermal stress. Furthermore, it requires complete disassembly for later maintenance, resulting in poor repair economy. Therefore, a modular forklift overhead guard is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a modular forklift overhead guard.

[0005] The technical solution adopted by this utility model to solve its technical problem is a modular forklift top guard, including a support frame and a side frame. A sleeve is fixedly connected to the top of the support frame, and a telescopic rod is movably inserted into the top of the sleeve. The bottom end of the telescopic rod is fixedly connected to the top of a limiting plate. The limiting plate is movably installed inside the sleeve. A spring is vertically installed inside the sleeve, and the top end of the spring is fixedly connected to the bottom end of the limiting plate. The top end of the telescopic rod is inserted into the bottom end of the top guard.

[0006] The side frames are arranged in two sets opposite each other, and the support frame and the top cover frame are installed between the two sets of side frames.

[0007] By adopting the above technical solution, the support frame can quickly position and adjust the spacing of multiple support frames by using the slots of the insert blocks and the side frame, combined with the sliding connection of the connecting rod and the slide groove. During installation, only the horizontal sliding of the support frame is required to accurately align with the slot. The top cover frame is fixed by the threaded holes of the bolts and the telescopic rod, making disassembly and maintenance convenient. This modular design greatly improves the installation efficiency.

[0008] The top support frame and the support frame adopt a spring buffer structure. When the top is subjected to impact, the telescopic rod compresses the spring and absorbs energy through elastic deformation. The limit plate controls the displacement amplitude, effectively reducing local stress concentration and significantly enhancing the compressive strength.

[0009] Specifically, slots are provided on the side of the two sets of side frames that are close to each other. There are multiple slots, and the slots are used for inserting plugs. The plugs are fixedly connected to one end of the support frame.

[0010] By adopting the above technical solution, the support frame is horizontally positioned by the plug at one end and the slot on the side frame. During installation, the plug needs to be aligned with the slot, and then the two support frames are slid horizontally to move them away from each other until the plug is fully embedded in the slot.

[0011] Specifically, the other end of the support frame is provided with a sliding groove, which is used for inserting one end of the connecting rod.

[0012] By adopting the above technical solution, the two ends of the connecting rod are respectively inserted into the grooves of two adjacent support frames to form a sliding connection structure. Through the guiding effect of the grooves, the support frame can move laterally along the connecting rod, which facilitates the adjustment of the distance between the two support frames, while maintaining the stability of the overall frame and providing adjustment space for the precise docking of the subsequent insert and slot.

[0013] Specifically, the top of the telescopic rod is provided with a threaded hole, which is adapted to the bolt thread, and the bolt is installed on the top of the top cover frame.

[0014] By adopting the above technical solution, after the top cover is closed, the pre-drilled hole at its bottom aligns with the top of the telescopic rod. The operator screws a bolt into the top of the top cover, allowing it to pass through the top cover and be screwed into the threaded hole of the telescopic rod. The threaded engagement achieves a rigid fixation between the top cover and the support frame. This structure ensures both a stable connection and ease of disassembly and maintenance.

[0015] Specifically, the top cover has ventilation slots inside, and there are multiple ventilation slots.

[0016] By adopting the above technical solution, the ventilation slots are distributed longitudinally along the inside of the top cover frame to form an air circulation channel.

[0017] The beneficial effects of this utility model are:

[0018] (1) The modular forklift top guard described in this utility model has a support frame that is engaged with the slot of the side frame by insert block, and the sliding connection of the connecting rod and the slide groove is combined to realize the rapid positioning and spacing adjustment of multiple support frames. During installation, only the horizontal sliding support frame is needed to accurately align with the slot. The top guard is fixed by bolts and the threaded holes of the telescopic rod, making disassembly and maintenance convenient. This modular design greatly improves the installation efficiency.

[0019] (2) The modular forklift top guard described in this utility model adopts a spring buffer structure between the top guard and the support frame. When the top is subjected to impact, the telescopic rod compresses the spring and absorbs energy through elastic deformation. The limiting plate controls the displacement amplitude, effectively reducing local stress concentration and significantly enhancing the compressive strength. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As one embodiment of this utility model, such as Figures 1-4 As shown, the modular forklift overhead guard of this utility model includes a support frame 5 and a side frame 1. The top end of the support frame 5 is fixedly connected to a sleeve 10. The top end of the sleeve 10 is movably inserted with a telescopic rod 9. The bottom end of the telescopic rod 9 is fixedly connected to the top end of a limiting plate 14. The limiting plate 14 is movably installed inside the sleeve 10. A spring 13 is vertically installed inside the sleeve 10. The top end of the spring 13 is fixedly connected to the bottom end of the limiting plate 14. The top end of the telescopic rod 9 is inserted into the bottom end of the overhead guard 2.

[0028] The side frame 1 is provided in two sets opposite to each other, and the support frame 5 and the top cover frame 2 are installed between the two sets of side frames 1.

[0029] In use, the top cover 2 is connected to the support frame 5 via the telescopic rod 9. When the top cover 2 is impacted by a heavy object, the telescopic rod 9 is compressed downwards and compresses the spring 13. The spring 13 absorbs the impact energy through elastic deformation, and the limiting plate 14 restricts the displacement range of the telescopic rod 9, thereby achieving a buffer protection function. The telescopic structure between the top cover 2 and the support frame 5 enhances the overall compressive strength.

[0030] It should be noted that the two side frames 1 are fixedly installed on both sides of the forklift cab. The bottom of the overhead guard 2 has multiple holes that allow the top of the telescopic rod 9 to be inserted. The multiple springs 13 can raise the overhead guard 2 to a certain height.

[0031] The present invention also includes that the two sets of side frames 1 are provided with slots 7 on the side that are close to each other. There are multiple slots 7, and the slots 7 are used for the insertion of plugs 11. The plugs 11 are fixedly connected to one end of the support frame 5.

[0032] In use, the support frame 5 is laterally positioned by the insert 11 at one end and the slot 7 on the side frame 1. During installation, the insert 11 needs to be aligned with the slot 7, and then the two support frames 5 are slid horizontally to move them away from each other until the insert 11 is fully embedded in the slot 7.

[0033] The present invention also includes a groove 12 provided at the other end of the support frame 5, the groove 12 being used for inserting one end of the connecting rod 6.

[0034] In use, the two ends of the connecting rod 6 are respectively inserted into the sliding grooves 12 of the two adjacent support frames 5 to form a sliding connection structure. Through the guiding action of the sliding grooves 12, the support frame 5 can move laterally along the connecting rod 6, which facilitates the adjustment of the distance between the two support frames 5, while maintaining the stability of the overall frame and providing adjustment space for the precise docking of the subsequent insert 11 and slot 7.

[0035] The present invention also includes a threaded hole 8 at the top of the telescopic rod 9, the threaded hole 8 being threadedly adapted to the bolt 4, and the bolt 4 being installed at the top of the top cover 2.

[0036] In use, after the top cover 2 is closed, its bottom pre-drilled hole aligns with the top of the telescopic rod 9. The operator screws the bolt 4 into the top of the top cover 2, allowing it to pass through the top cover 2 and be screwed into the threaded hole 8 of the telescopic rod 9. The threaded engagement achieves a rigid fixation between the top cover 2 and the support frame 5. This structure ensures both a stable connection and ease of disassembly and maintenance.

[0037] This utility model also includes a ventilation groove 3 inside the top cover 2, and the ventilation groove 3 has multiple locations.

[0038] When in use, the ventilation slots 3 are distributed longitudinally along the inside of the top cover 2 to form an air circulation channel.

[0039] It should be noted that the ventilation slot 3 and the support frame 5 are staggered.

[0040] In use, this invention first inserts both ends of the connecting rod 6 into the sliding grooves 12 at both ends of the two support frames 5, allowing the two support frames 5 to be slidably connected via the connecting rod 6. Then, the two support frames 5 are placed horizontally between the two side frames 1, with the inserts 11 at one end of each support frame 5 aligned with the slots 7 opposite each other on one side of the two side frames 1. The two support frames 5 are then slid apart to allow the inserts 11 to be inserted into the slots 7. This method is used to install multiple support frames 5 and connecting rods 6 between the two side frames 1. Continue until all slots 7 are filled. Then, place the top cover 2 horizontally on top of the support frame 5, allowing the telescopic rod 9 to be inserted into the hole at the bottom of the top cover 2. Install and screw the bolt 4 from the top of the top cover 2 until the bolt 4 can be screwed into the threaded hole 8 at the top of the telescopic rod 9. In this way, the top cover 2 is fixedly connected to the support frame 5. When a heavy object falls on top of the top cover 2, it will compress the spring 13. The spring 13 can buffer a certain impact force, thereby strengthening the pressure resistance of the top cover 2.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
