Description

Technical Field

[0001] This utility model relates to the field of forklift technology, specifically to a pull-out waterproof groove device for electric forklifts and a forklift. Background Technology

[0002] As electric forklift technology matures and costs gradually decrease, the market is increasingly accepting large-tonnage electric forklifts, and they are appearing more and more in outdoor areas, making rainy weather operations inevitable.

[0003] Although the protection level of key components of electric forklifts, such as the three electric components (motor, electronic control and battery), has been improved to IP67, the protection level of the whole machine can only reach IPX5. At this time, auxiliary waterproof grooves can reduce the probability of electrical components being directly eroded by rainwater to a certain extent.

[0004] Current waterproofing groove designs fall into two categories. One type is the "patch-type" waterproofing groove, which adds a corresponding waterproofing groove to the bottom of the gap between the cover components. The overall waterproofing device consists of multiple independent small waterproofing grooves. Its advantage is that it does not affect maintainability, but its disadvantage is that the protection is slightly insufficient. The other type is the "integral" waterproofing groove, which adds a single waterproofing groove to the bottom of the cover component. Its advantage is that it provides good protection, but its disadvantage is that it is more complicated to disassemble and assemble, which has a certain impact on maintainability.

The support assembly 3 is disposed on the lower surface of the waterproof channel assembly 1 and is used to support the waterproof channel assembly 1. This invention can effectively prevent the electrical components of the forklift from being directly eroded by rainwater, protecting electrical safety. The symmetrically distributed bracket assembly 12 and the sliding cooperation with the guide rail assembly 2 realize the smooth movement and adjustment function of the waterproof channel 11, which can be pulled out from the guide rail assembly 21 for maintenance. Compared with existing "patch-type" waterproof channels, the waterproof channel device of this utility model has better protection; compared with existing "fixed" waterproof channels, the "drawer-type" waterproof channel device of this utility model is convenient for daily maintenance of components. The waterproof channel device of this utility model takes into account waterproof performance, structural strength and maintainability.

[0077] In this embodiment, the specific structure of the guide rail assembly 2 can be of various types known to those skilled in the art, provided that it provides a rail to the bracket assembly 12. In one example of this utility model, such as... Figure 4 As shown, the guide rail assembly 2 includes a guide rail 21 and a first bracket 22. The first bracket 22 is vertically mounted on the guide rail 21 and is used to connect the guide rail 21 and the forklift. Considering the need to enhance the connection strength between the guide rail 21 and the first bracket 22, the guide rail assembly 2 also includes a first stiffening plate 23. The first stiffening plate 23 is symmetrically arranged on both sides of the first bracket 22, and the bottom edge of the first stiffening plate 23 is connected to the upper edge of the guide rail 21, and the side edge of the first stiffening plate 23 is connected to the side edge of the bracket. The bracket assembly 12 is symmetrically fixed on both sides of the waterproof groove 11, forming a sliding pair with the two sets of parallel guide rails 21. The guide rail 21 is connected to the forklift by the vertically mounted first bracket 22, and the first stiffening plates 23 on both sides adopt a triangular reinforcement structure, so that the guide rail 21 and the bracket form a rigid whole. When the bracket assembly 12 slides longitudinally along the guide rail 21, it drives the waterproof groove 11 to move synchronously through mechanical linkage, realizing the position adjustment function. At the same time, the symmetrical layout of the guide rail 21 and the support of the first stiffening plate 23 ensure that the sliding process is stable and without deviation.

[0078] In this embodiment, the specific structure of the bracket assembly 12 can be of various types known to those skilled in the art, provided that it satisfies the requirement of moving the waterproof groove 11 on the guide rail assembly 2. In one example of this utility model, such as... Figure 5As shown, the bracket assembly 12 includes a second bracket 121, a mounting shaft 122, a bearing 123, and a vertical plate 124. The second bracket 121 is disposed on the upper surface of the waterproof groove 11, and its bottom is fixedly connected to the waterproof groove 11. The mounting shaft 122 is symmetrically disposed on the side of the second bracket 121 away from the guide rail 21 along the horizontal direction. The bearing 123 is sleeved on the mounting shaft 122 and rolls along the track of the guide rail 21 to drive the waterproof groove 11 to move horizontally. Furthermore, a shoulder is provided at the end of the mounting shaft 122 away from the guide rail 21. This shoulder and the bearing 123 are interference-fitted for axial positioning of the bearing 123 to prevent lateral displacement. The second bracket 121 is fixed to the upper surface of the waterproof groove 11 by its bottom, and the bearing 123 is sleeved on its horizontally symmetrical mounting shaft 122, with the bearing 123 rolling within the track of the guide rail 21. When an external force is applied, the bearing 123 rolls along the guide rail 21, causing the second bracket 121 and the waterproof groove 11 to slide as a whole. The upright plate 124 stands vertically at the bottom of the second bracket 121 and forms a clearance fit with the side wall of the guide rail 21, which restricts lateral displacement during the sliding process and ensures the stability of the movement trajectory.

[0079] To further limit the relative position of the guide rail 21 and the second bracket 121, in this embodiment, the top of the upright plate 124 is provided with a through hole, and the guide rail 21 is provided with a fixing hole corresponding to the through hole, and the fixing hole and the through hole are connected by bolts. Furthermore, to improve the applicability of the device, the number of fixing holes can be multiple as known to those skilled in the art; in one example of this utility model, the number of fixing holes can be seven. By coaxially aligning the through hole of the upright plate 124 with a fixing hole of the guide rail, the waterproof groove 11 can be positioned and fixed.

[0080] In this embodiment, the structure of the support assembly 3, while satisfying the requirements of the support waterproof groove assembly 1, can be of various types known to those skilled in the art. In one example of the utility model, such as... Figure 6As shown, the support assembly 3 includes a strut assembly 31. The strut assembly 31 is disposed on the lower surface of the waterproof groove 11 and perpendicular to the direction of the guide rail assembly 2, and is used to support one end of the waterproof groove assembly 1. Specifically, the strut assembly 31 may include a strut 311, a rubber sleeve 312, and a mounting plate 313. The strut 311 supports one side of the waterproof groove 11, the rubber sleeve 312 is fitted onto the strut 311, and the mounting plate 313 is fixedly connected to the bottom of the strut 311, connecting the strut 311 and the forklift. The strut 311 is fixed to the forklift body via the mounting plate 313 at the bottom, with its top supporting one side of the waterproof groove 11. The rubber sleeve 312 serves both buffering and anti-slip functions, absorbing vibrations and impacts during vehicle movement, while ensuring a tight fit of the support contact surface through elastic deformation. Furthermore, the maximum height of the strut 311 is 3-8 mm lower than the height of the lower surface of the waterproof groove 11. By setting the guide rail assembly 2 in a front-high-rear-low posture, and the waterproof channel assembly 1 deforming in the front-high-rear-low posture after installation due to its own weight and / or the weight of rainwater, the waterproof channel assembly 1 is ultimately arranged at an elevation angle of 0° to 5°, which is beneficial for guiding rainwater out.

[0081] In this embodiment, it is necessary to ensure the waterproof effect of the waterproof groove 11. Therefore, each side of the waterproof groove 11 is provided with a water-blocking plate to prevent rainwater backflow and seepage. The waterproof groove is polygonal, and the waterproof groove and the water-blocking plate are welded together to ensure that all gaps are sealed and leak-proof. The edge of the waterproof groove 11 is provided with multiple drainage holes to facilitate the drainage of rainwater.

[0082] In this embodiment, the structure of the support assembly 3, while satisfying the requirements of the support waterproof groove assembly 1, can be of various types known to those skilled in the art. In one example of the utility model, such as... Figure 7 and Figure 8 As shown, the support assembly 3 includes a support component 32. The support component 32 is symmetrically arranged on the lower surface of the waterproof groove 11 and parallel to the direction of the guide rail assembly 2, serving to support both ends of the waterproof groove assembly 1. Specifically, the support component 32 includes a bracket 321, a third support 322, and a second stiffener 323. The bracket 321 supports the opposite sides of the waterproof groove 11. The third support 322 is disposed on the lower surface of the bracket 321 and connects the bracket 321 to the forklift. The upper surface of the stiffener is connected to the lower surface of the bracket 321, and the side of the second stiffener 323 is connected to the side of the third support 322 to enhance the connection strength between the bracket 321 and the third support 322. The bracket 321 directly bears the weight of both sides of the waterproof groove 11, distributing it to the lower structure. The third support 322 vertically connects the bracket 321 to the forklift body, transferring the load to the forklift.

[0083] In this embodiment, the connection method between the waterproof groove 11 and the support rod 311 can be one of many known to those skilled in the art. In one example of this utility model, such as... Figure 2 As shown, a hook is provided on the lower surface of the waterproof groove 11, and the support rod 311 and the waterproof groove 11 are connected by the hook. The connection method between the waterproof groove 11 and the bracket 321 can be various methods known to those skilled in the art. In one example of this utility model, such as... Figure 9 , Figure 10 and Figure 11 As shown, the edge of the waterproof groove 11 is provided with a first mounting hole, and the edge of the bracket 321 is provided with a second mounting hole corresponding to the first mounting hole. The first mounting hole and the second mounting hole are connected by bolts and nuts. Furthermore, the shape of the bolt can be various that are known to those skilled in the art; in one example of this utility model, the bolt can be butterfly-shaped. The waterproof groove 11 is fixedly connected by the butterfly bolt, nut, and bracket 321. The waterproof groove 11 and the bracket assembly 12 are arranged in a front-high, rear-low posture. The pitch angle of the waterproof groove 11 can be further adjusted by adjusting the depth of the nut entering the bolt.

[0084] In this embodiment, it is necessary to ensure the waterproof effect of the waterproof groove 11. Therefore, each side of the waterproof groove 11 is provided with a baffle plate to prevent rainwater backflow and seepage. The waterproof groove and the baffle plate are injection molded as one piece for easy pulling. Furthermore, the shape of the waterproof groove 11 can be various that are known to those skilled in the art. In one example of this utility model, the waterproof groove 11 can be polygonal, and to enhance the rigidity of the middle part of the waterproof groove 11, such as... Figure 12 and 13 As shown, the middle part of the waterproof groove 11 is recessed inward to form a groove, which effectively reduces the deformation caused by the middle part sinking.

[0085] On the other hand, this utility model provides a forklift, which includes a body 4, a crossbeam 5, a seat cover 6, a gas spring 7, a water tank cover 8, and any of the above-mentioned waterproofing devices.
