Description

Technical Field

[0001] This utility model belongs to the technical field of material handling vehicles, and in particular relates to an anti-collision structure for material handling vehicles. Background Technology

[0002] Material handling vehicles are motorized vehicles specifically designed for handling, loading, unloading, and transporting various materials and goods in factories, warehouses, logistics centers, construction sites, and other locations. They are widely used in manufacturing, construction, retail, and logistics industries and are important tools for improving work efficiency and reducing manual labor intensity. Common types of material handling vehicles include forklifts, electric pallet trucks, manual hydraulic pallet trucks, and stackers. These devices can meet diverse handling needs through different drive methods (such as electric, fuel, or manual) and structural designs (such as lifting devices, forks, and platforms). For example, forklifts are suitable for stacking and unloading heavy goods, while manual hydraulic pallet trucks are suitable for short-distance transportation of light goods.

[0003] Currently, most existing anti-collision structures use rubber strips to absorb collision energy. However, as the rubber strips accumulate over time, they will age, making it difficult to replace them once they have aged. Utility Model Content

[0033] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0034] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] Please see Figures 1 to 5 This utility model provides a material handling vehicle anti-collision structure, including a vehicle body 1, a fixed guardrail 2 fixedly connected to the upper side of the vehicle body 1; the fixed guardrail 2 is located on the right side of the vehicle body 1; a handle 3 is fixedly connected to the fixed guardrail 2; cargo protective parts are installed on both side walls of the vehicle body 1; and an anti-collision component is installed on the side of the vehicle body 1 away from the fixed guardrail 2.

[0036] Using the above solution: When loading goods, the staff first moves the vehicle body 1 to the designated area, then places the goods on the vehicle body 1. Next, the cargo protection component is flipped to a preset angle and works in conjunction with the fixed guardrail 2 to protect the goods, effectively preventing the goods from tilting during transportation. In addition, when the staff pushes the vehicle body 1 with the handle 3, the anti-collision component protects the vehicle body 1, thereby improving the overall safety.

[0037] Furthermore, the anti-collision component includes a first sliding rod 4 fixedly connected to the left side of the vehicle body 1; telescopic rods 5 are provided on both the upper and lower sides of the first sliding rod 4; one end of the telescopic rod 5 is fixedly connected to the vehicle body 1, and the other end of the telescopic rod 5 is fixedly connected to a support frame 6.

[0038] Furthermore, the anti-collision assembly also includes a first spring 7 sleeved on the outside of the telescopic rod 5; one end of the first spring 7 is fixedly connected to the vehicle body 1, and the other end of the first spring 7 is fixedly connected to the support frame 6; two symmetrical first fixing blocks 8 are fixedly connected to the back of the support frame 6, and two symmetrical first sliders 9 are slidably connected to the first sliding rod 4; a first connecting plate 10 is rotatably connected between the first fixing block 8 and the first slider 9, and a second spring 11 is fixedly connected between the first sliders 9.

[0039] Furthermore, a clamping block 12 is inserted into the support frame 6; a rubber strip 13 is installed on the clamping block 12, and two symmetrical first threaded holes 14 are opened on both the clamping block 12 and the rubber strip 13.

[0040] A bolt 15 is threadedly connected to the first threaded hole 14.

[0041] The above scheme is adopted as follows: When in use, the vehicle body 1 is moved by the staff. When the vehicle body 1 collides with an object, the rubber strip 13 first contacts the object and absorbs part of the impact force. Then, the rubber strip 13 pushes the support frame 6 to move backward, causing the telescopic rod 5 and the first spring 7 to be compressed, further absorbing and buffering the impact force. During the process of the support frame 6 moving backward, the support frame 6 will push the first fixed block 8 and the first connecting plate 10, so that the two first sliders 9 are close to each other on the first sliding rod 4, while compressing the second spring 11, providing buffer for the impact force again. Through the first spring 7 and the second spring 11 absorbing the impact force in a secondary and tertiary manner at different stages, the impact on the vehicle body 1 and the object is reduced, and the overall impact absorption efficiency is further improved.

[0042] It should be noted that when the rubber strip 13 needs to be replaced, the staff removes the bolt 15 from the clamping block 12 and the rubber strip 13. At this time, the rubber strip 13 is removed from the clamping block 12, the new rubber strip 13 is reinstalled, and the bolt 15 is used to fix the rubber strip 13 again, thus completing the replacement of the rubber strip 13.

[0043] Furthermore, the cargo protection component includes two side guardrails 16 rotatably connected to the side wall of the vehicle body 1; a sleeve 17 is fixedly connected to the top of the side guardrail 16, and a second sliding rod 18 is slidably connected inside the sleeve 17.

[0044] Furthermore, the cargo protection component also includes a fixing rod 19 fixedly connected to the fixed protective railing 2; the fixing rod 19 is aligned with the second sliding rod 18, and one end of the second sliding rod 18 can be inserted into the fixing rod 19.

[0045] Furthermore, a first fixing plate 20 is installed at one end of the sleeve 17; a second fixing plate 21 is installed at one end of the second sliding rod 18 and is aligned with the first fixing plate 20; a plurality of third springs 22 are installed between the first fixing plate 20 and the second fixing plate 21; a locking rod 23 is inserted into the top of the first fixing plate 20 and the second fixing plate 21.

[0046] Using the above solution: When in use, after the goods are loaded, the staff flips the side guards on both sides of the vehicle body 1 to a vertical position, aligns one end of the second sliding rod 18 with the round hole on the fixed rod 19, and pushes the second sliding rod 18 to slide in the sleeve 17 in a preset direction. During this process, the second sliding rod 18 drives the second fixed piece 21 to move synchronously and compresses the third spring 22. When the second sliding rod 18 moves to the preset position, the second sliding rod 18 will be inserted into the fixed rod 19. Then, the locking rod 23 is inserted into the first fixed piece 20 and the second fixed piece 21, thereby fixing the position of the side guardrail 16. Together with the fixed guardrail 2, it effectively prevents the goods from tilting during transportation.

[0047] It should be noted that when unloading goods, the staff removes the locking rod 23 from the first fixing plate 20 and the second fixing plate 21. Using the elasticity of the third spring 22, the second sliding rod 18 is pulled to move in the opposite direction in the sleeve 17, so that the second sliding rod 18 is disengaged from the fixing rod 19. Then the side guardrail 16 can be flipped to a horizontal angle.

[0048] The working principle of this utility model:

[0049] When loading goods, the staff first moves the vehicle body 1 to the designated area, then places the goods on the vehicle body 1. The staff then flips the side guardrails on both sides of the vehicle body 1 to a vertical position and aligns one end of the second sliding rod 18 with the round hole on the fixed rod 19. The staff pushes the second sliding rod 18 to slide in the sleeve 17 in a preset direction. During this process, the second sliding rod 18 drives the second fixed piece 21 to move synchronously and compresses the third spring 22. When the second sliding rod 18 moves to the preset position, it inserts into the fixed rod 19. Next, the locking rod 23 is inserted into the first fixed piece 20 and the second fixed piece 21, thereby fixing the position of the side guardrail 16. Together with the fixed guardrail 2, this effectively prevents the goods from falling into the guardrail. During transportation, a tilt occurs. When the vehicle body 1 collides with an object, the rubber strip 13 first contacts the object and absorbs part of the impact force. Subsequently, the rubber strip 13 pushes the support frame 6 to move backward, causing the telescopic rod 5 and the first spring 7 to be compressed, further absorbing and buffering the impact force. During the backward movement of the support frame 6, the support frame 6 pushes the first fixed block 8 and the first connecting plate 10, causing the two first sliders 9 to move closer to each other on the second sliding rod 4, while compressing the second spring 11, providing buffering for the impact force again. Through the second and third absorption of the impact force by the first spring 7 and the second spring 11 at different stages, the impact on the vehicle body 1 and the object is reduced, further improving the overall impact absorption efficiency.
