Description

Technical Field

[0001] The utility model relates to the technical field of sliding mechanisms, in particular to a guide rail assembly and a sliding mechanism. Background Art

[0002] In work vehicles, a sliding mechanism is often used to achieve horizontal sliding of the work head. For example, a landscaping pruning vehicle is a specialized maintenance vehicle used for pruning hedges and slopes along highways. Its frame carries the work head during operations. Adjusting the direction or range of operation often requires the use of a sliding mechanism. Specifically, the work head is mounted on a sliding base, and the guide rail assembly is mounted on the frame, enabling horizontal movement of the work head without the vehicle moving.

[0003] Because the working head of this type typically needs to be extended outward to operate, and considering the weight of the working head, to ensure its stability during movement, a dual-track guide assembly is usually required to provide support and guidance, and then the two tracks are fixedly connected by a support frame. This structure not only brings weight issues, which are not conducive to lightweighting the entire machine, but also makes it inconvenient to manufacture. Utility Model Content

[0027] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] As shown in the accompanying drawings, this embodiment provides a guide rail assembly, which includes an upper linear rail 1 and a lower linear rail 2 arranged in parallel, and the upper linear rail 1 and the lower linear rail 2 are connected with a supporting column 5. The upper linear rail 1, the lower linear rail 2 and the supporting column 5 form a frame structure, and the supporting column 5 is fixedly connected to the upper linear rail 1 and the lower linear rail 2 respectively through a connecting block, and each connecting block is independent of each other. In this embodiment, the supporting column 5 is fixedly connected to the upper linear rail 1 through an upper connecting block 3, and the supporting column 5 is fixedly connected to the lower linear rail 2 through a lower connecting block 4;

[0029] It also includes a reinforcing diagonal brace 6 connected between the upper linear rail 1 and the lower linear rail 2. The reinforcing diagonal brace 6 is fixedly connected to the upper linear rail 1 and the lower linear rail 2 respectively through a connecting block. The connecting blocks are independent of each other. In this embodiment, the reinforcing diagonal brace 6 is fixedly connected to the upper linear rail 1 through a middle connecting block 31, and the reinforcing diagonal brace 6 is fixedly connected to the lower linear rail 2 through a lower connecting block 4. The middle connecting block 31 and the lower connecting block 4 are staggered in an upper and lower manner.

[0030] Among them, multiple connecting blocks are arranged at intervals in the length direction of the linear rail, and at least some connecting parts (preferably the connecting parts near the middle of the guide rail assembly) also serve as mounting seats for connecting to external racks, that is, in actual use, the guide rail assembly is connected to the corresponding rack through the connecting blocks so that the guide rail assembly can be installed on the rack for use.

[0031] The connecting block is provided with a clamping slot 7 corresponding to the upper linear rail 1 and the lower linear rail 2. The upper linear rail 1 and the lower linear rail 2 are partially embedded in the clamping slot 7 and fixedly connected to the connecting block.

[0032] In this embodiment, the guide rail assembly is divided into multiple parts: an upper linear rail 1, a lower linear rail 2, a connecting block, a supporting column 5 and a reinforcing diagonal brace 6, so that each component can be processed separately and then assembled into the above-mentioned guide rail assembly structure, which is convenient for production and processing. The upper linear rail 1 and the lower linear rail 2 can adopt a horizontally placed steel pipe structure, the connecting block can adopt a channel steel structure, and its slots 7 are all rectangular slots. The supporting column 5 and the reinforcing diagonal brace 6 can adopt steel structural parts, which are simple and easy to obtain. Moreover, while ensuring its own strength, compared with the traditional integrated guide rail assembly, the dead weight of the guide rail assembly is greatly reduced, which is conducive to the lightweight design of the equipment.

[0033] In other embodiments, the upper linear rail 1 and the lower linear rail 2 may also be configured as columnar structures.

[0034] In a preferred embodiment of the present invention, the circumferential surfaces of the upper linear rail 1 and the lower linear rail 2 are provided with positioning platforms 8 adapted to the slots 7, which are fixed with the right-angled edges at the slots of the corresponding connecting blocks through concave-convex cooperation to limit the rotation of the upper linear rail 1 and the lower linear rail 2 relative to the connecting blocks along the circumferential direction, thereby ensuring the limiting effect and facilitating processing.

[0035] In a preferred embodiment of the present invention, the upper linear rail 1 and the lower linear rail 2 are provided with through holes 101 passing through the inner and outer walls thereof toward the connecting block. The upper linear rail 1 and the lower linear rail 2 are fixedly connected to the connecting block by bolts 71 passing through the through holes 101. At this time, the bolt heads are placed inside the linear rails, and the interior of the linear rails is preferably provided with a platform 102 adapted to the bolt heads to facilitate the tightening of the bolts.

[0036] One embodiment of the present invention provides a sliding mechanism, which includes the above-mentioned guide rail assembly and a sliding seat slidably connected to the guide rail assembly. The sliding seat includes an upper slider 9, a lower slider 10, and a support frame 11 fixedly connected therebetween. The support frame 11 and the upper slider 9 and the lower slider 10 are of a separate structure for easy installation. The upper slider 9 is located at the top of the upper linear rail 1 and is slidably connected to the upper linear rail 1. The upper slider 9 is provided with a first slide 12 corresponding to the upper linear rail 1. The lower slider 10 is located at the bottom of the lower linear rail 2 and is slidably connected to the lower linear rail 2. The lower slider 10 is provided with a second slide 13 corresponding to the upper linear rail 1. When in use, a working head connecting frame 17 is fixedly connected to the sliding seat. Under the action of an external source drive, the sliding seat causes the upper slider 9 and the lower slider 10 to slide synchronously on the upper linear rail 1 and the lower linear rail 2, respectively, to achieve horizontal sliding of the working head installed on the sliding seat. In this embodiment, the first slide 12 and the second slide 13 are both arc-shaped slides to adapt to the outer shapes of the upper and lower linear rails.

[0037] In a preferred embodiment of the present invention, the first chute 12 and the second chute 13 are two arc-shaped chute that can be assembled into a circle. Figure 4 and Figure 5 As shown, for the upper slider 9, the end of the first slide 12 away from the work head connecting frame 17 is higher than the opposite end, and for the lower slider 10, the end of the second slide 13 away from the work head connecting frame 17 is lower than the opposite end. The advantage of this structure is that when one side of the sliding seat carries a heavy work head, it can ensure the stability of the sliding seat during sliding.

[0038] In a preferred embodiment of the present invention, the sliding mechanism further comprises a sliding drive 14 and a gear rack structure. The sliding drive 14 is fixedly mounted on the sliding seat and utilizes a drive motor. The rotary output shaft of the sliding drive 14 is coaxially fixedly connected to a gear 15. A rack 16 is fixedly mounted on the side of the guide rail assembly and meshes with the gear 15. The length of the rack 16 is aligned with the axial direction of the upper linear rail 1. During operation, the drive motor drives the gear 15 to rotate about its own axis. Combined with the meshing relationship between the gear 15 and the rack fixed to the guide rail assembly, the sliding seat can be driven to slide on the guide rail assembly.
