Description

Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to a universal switch rail for window cleaning machines. Background Technology

[0002] In the modern building cleaning industry, track-mounted window cleaning machines have become the core equipment for cleaning the exterior walls and windows of high-rise buildings and large public buildings due to their controllable operating range and relatively convenient operation. However, the track-mounted window cleaning machines widely used in the industry currently have significant limitations in their track structure—the vast majority of tracks adopt a regular straight rail design. While this structure can meet the basic cleaning needs of flat and regular building facades, it exposes serious functional shortcomings in complex building shapes or special cleaning scenarios.

[0003] From a practical application perspective, with the innovation of architectural design concepts, buildings with curved exterior walls, irregularly shaped bay windows, progressively receding facades, and eaves or decorative lines are becoming increasingly common. When a window cleaning machine runs along a straight rail, the fixed direction of the rail directly limits the range of distance adjustment between the machine's working arm and the surface to be cleaned: when facing protruding structures on the building facade, the rail cannot bend or shift synchronously with the building's shape, making it difficult for the working end of the window cleaning machine to get close to the surface of the protruding area, forming a ring-shaped or strip-shaped cleaning blind spot; while when dealing with recessed areas such as window openings and under eaves, the straight trajectory of the rail prevents the window cleaning machine from penetrating deep into the recessed space, only able to clean the edge of the recessed area, leaving the core area in a "cleaning dead corner" state for a long time.

[0004] Therefore, a universal switch rail for window cleaning machines needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a universal branch rail for window cleaning machines. Through the flexible structural design of the branch rail, this utility model breaks the limitation of the fixed direction of straight rails, enabling the window cleaning machine to adjust its running trajectory according to the shape of the building facade. Furthermore, the bottom block can be assembled with the first or second rail, thus avoiding the situation where the first or second rail deviates during operation, causing the cleaning machine to malfunction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A universal fork rail for a window cleaning machine includes multiple base blocks. The upper ends of multiple mating base blocks located on the front and rear sides are fixedly connected to a first rail. The upper ends of multiple mating base blocks located on the left side are fixedly connected to a second rail. The rear sides of the two first rails located on the front side are rotatably connected to a first swing leg. The upper end of the base block located in the middle is rotatably connected to a second swing leg. A first arc-shaped rail is provided between the first swing leg and the second swing leg.

[0008] Preferably, a first threaded post is fixedly connected to each of the plurality of base blocks, and a second threaded post is fixedly connected to the rear side of each of the plurality of base blocks located on the right side. Each of the plurality of first threaded posts has a first threaded layer, and each of the plurality of second threaded posts has a second threaded layer. A first strip plate is commonly fitted on every two mating first threaded posts, and a second strip plate is commonly fitted on every two mating second threaded posts. A first nut is threadedly connected to each of the plurality of first threaded posts, and a second nut is threadedly connected to each of the plurality of second threaded posts.

[0009] Preferably, each of the first and second strip plates has two threaded heads that mate with either the first or second nut fixedly connected to it.

[0010] Preferably, the second track is integrally formed from a straight track and a second arc track.

[0011] Preferably, the second swing leg is rotatably connected to the corresponding base block via a pivot, and the pivot is fixedly connected to the middle area of ​​the second swing leg.

[0012] Preferably, the first track, the second track, the first swing leg, and the second swing leg are all I-beams.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with existing technologies, this device can effectively break the limitations of fixed straight track direction. Through flexible track connection and track change design, it can adapt to complex building forms such as curved exterior walls, irregular bay windows, and cantilevered balconies. This allows the window cleaning machine to adjust its running trajectory according to the shape of the area to be cleaned, achieving comprehensive cleaning of raised areas, recessed spaces, and other areas that are difficult to reach with traditional straight tracks. This fundamentally reduces or even eliminates cleaning dead corners and improves the overall cleaning effect.

[0015] 2. Compared with the prior art, by setting the first threaded post, the first strip plate, the second threaded post and the second strip plate, multiple base blocks can be stably fixed in a row, so that the first track and the second track can be quickly assembled on a row of base blocks. At the same time, after the assembly is completed, the first strip plate and the second strip plate can be disassembled.

[0016] 3. Compared with the existing technology, by setting the second strip plate and the first strip plate, the assembled tracks that are on the same straight line can be connected together, or the second track can be perpendicularly connected to the first track, so as to avoid the first track and the second track from shifting due to the operation of the window cleaning machine.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-2 A universal fork rail for a window cleaning machine includes multiple base blocks 1. The upper ends of multiple mating base blocks 1 located on the front and rear sides are fixedly connected to a first rail 2. There are three first rails 2 on the left side and two on the right side. The upper ends of the multiple mating base blocks 1 on the left side are fixedly connected to a second rail 8. The rear sides of the two first rails 2 on the front side are rotatably connected to first swing legs 6. The direction of travel of the window cleaning machine is changed by rotating the two first swing legs 6 and the second swing legs 7. The middle base block 1... The upper end is rotatably connected to a second swing leg 7. The operation of the second swing leg 7 and the first swing leg 6 can be driven manually or electrically (similar to a train track). The second swing leg 7 is located between the two first tracks 2 on the left rear side. The second swing leg 7 is rotatably connected to the corresponding bottom block 1 through a rotating shaft. The rotating shaft is fixedly connected to the middle area of ​​the second swing leg 7. A first arc-shaped track is provided between the first swing leg 6 and the second swing leg 7. The second track 8 is integrally formed by a straight track and a second arc-shaped track. The first track 2, the second track 8, the first swing leg 6 and the second swing leg 7 are all I-beams.

[0022] Among them, a first threaded post 4 is fixedly connected to multiple base blocks 1, and a second threaded post 10 is fixedly connected to the rear side of multiple base blocks 1 on the right side. A first threaded layer is provided on multiple first threaded posts 4, and a second threaded layer is provided on multiple second threaded posts 10. A first strip plate 3 is sleeved on every two mating first threaded posts 4, and a second strip plate 9 is sleeved on every two mating second threaded posts 10. A first nut 5 is threadedly connected to multiple first threaded posts 4, and a second nut 11 is threadedly connected to multiple second threaded posts 10.

[0023] The first strip plate 3 and the second strip plate 9 are each fixedly connected to two threaded heads 12 that mate with the first nut 5 or the second nut 11. The first nut 5 and the second nut 11 can be threaded onto the threaded heads 12. When the first strip plate 3 and the second strip plate 9 are not in use, the first nut 5 and the second nut 11 can be stored to prevent them from being lost.

[0024] The functional principle of this utility model can be explained through the following operation: For the front and rear bottom blocks 1 on which the first track 2 needs to be laid, the first strip plate 3 is fitted onto every two mating first threaded posts 4, so that the bottom blocks 1 in the same row form a rigid connection through the first strip plate 3; then the first nut 5 is tightened until the first nut 5 is tightly fitted with the first strip plate 3, and the threaded locking structure of the first threaded post 4 is used to fix the bottom blocks 1 in the same row into a neat straight line array, so as to ensure that the first track 2 can be accurately laid on the top of multiple bottom blocks 1.

[0025] For the left bottom block 1 where the second track 8 needs to be laid, the same operating logic is used. The second strip plate 9 is fitted onto the second threaded post 10 of the corresponding bottom block 1 and locked by the second nut 11 to complete the array fixation of the left bottom block 1. After the first track 2 and the second track 8 are welded or bolted to the bottom block respectively, the first nut 5 and the second nut 11 can be unscrewed, and the first strip plate 3 and the second strip plate 9 can be removed to realize the reuse of assembly tools and reduce the cost of consumables.

[0026] In the initial state, the two first swing legs 6 and the second swing leg 7 are in a straight line, thus connecting the first track 2 together. When the window cleaning machine needs to switch from the connection of the two first tracks 2 to the connection of the first track 2 and the second track 8, the operator manually or electrically controls the two first swing legs 6 and the second swing leg 7 to rotate, thereby connecting the first track 2 and the second track 8 together through the first swing leg 6, the second swing leg 7 and the first arc track, thus changing the running direction of the window cleaning machine.

[0027] During the operation of the track, the first strip plate 3 connects the first track 2 located on the same straight line, and the second strip plate 9 connects the bottom block 1 below the first track 2 and the second track 8, so as to avoid the first track 2 and the second track 8 from shifting due to vibration during the operation of the window cleaning machine.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
