Description

Technical Field

[0001] This utility model relates to the field of crane track technology, and more specifically, to an automatic cleaning device. Background Technology

[0002] A flexible crane is a type of lifting machinery with a unique design concept. It mainly consists of rails, beams, transmission devices, KBK guide rails, electric hoists, and other parts. Compared with traditional rigid cranes, flexible cranes have the characteristics of flexibility and bendability, which can adapt to different lifting needs and can work freely in confined spaces. They also have the advantages of simple structure, convenient operation, stable operation, and small space occupation. In order to ensure the stability of the crane's movement, the rails need to be cleaned.

[0003] Based on the above, the inventors have discovered that existing cleaning devices are directly installed on the track for cleaning. However, flexible cranes are modular in design, and the track length is adjusted according to lifting requirements. Therefore, traditional fixed cleaning devices have limited effectiveness in cleaning the tracks of flexible cranes. In view of this, the inventors have researched and improved the existing structure to provide an automatic track cleaning device for flexible cranes, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic track cleaning device for flexible cranes. This solution is equipped with a jacking component, which allows the cleaning device to automatically adjust on the outside of the track and move along the track for convenient cleaning. Furthermore, the cleaning device is a split type, and the two sides of the cleaning device are symmetrical, which facilitates installation and disassembly and makes it easy to maintain and replace later.

[0006] Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An automatic track cleaning device for a flexible crane includes a track. A lower mounting base and an upper mounting base are symmetrically arranged on the outer side of the track. Support plates are fixedly connected to both ends of the lower mounting base and both ends of the upper mounting base. A pair of hydraulic cylinders are fixedly connected to the bottom of the lower mounting base and the upper mounting base. A moving plate is fixedly connected to the output end of the hydraulic cylinder. A positioning mechanism is provided above the moving plate.

[0009] The positioning mechanism includes a drive motor, the output end of which is fixedly connected to a gear ring, both sides of which are meshed with gear bars, and one end of the gear bars is fixedly connected to a positioning block.

[0010] Furthermore, the connection between the lower mounting base and the upper mounting base, as well as the connection between the two adjacent support plates, are all threaded with bolts.

[0011] Furthermore, one end of the support plate is U-shaped, and a cleaning pad is fixedly connected to the inner side of one end of the support plate, with the cleaning pad fitting against the outer surface of the track.

[0012] Furthermore, the drive motor is located at the bottom of the moving plate and is fixedly connected to the moving plate, with the two racks arranged in opposite directions.

[0013] Furthermore, both the toothed ring and the toothed rod are located inside the movable plate, with the toothed ring being movably connected to the movable plate and the toothed rod being slidably connected to the movable plate.

[0014] Furthermore, grooves are provided on both sides of the track, and the positioning block is adapted to the groove.

[0015] Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, the first pair of positioning blocks are fixed on the outside of the track by using a toothed ring and a toothed rod. Then, the hydraulic cylinder close to the direction of movement is activated to drive the corresponding moving plate to move, so that the second pair of positioning blocks fit into the groove on the side of the track. Then, the first pair of positioning blocks are separated from the track. Then, the hydraulic cylinder close to the direction of movement is returned to oil. Under the pressure of the returned oil, the entire mounting seat moves on the outside of the track, driving the support plate to slide on the outside of the track. The cleaning pad cleans the track. Compared with the prior art, the push assembly can automatically adjust the cleaning device on the outside of the track and move along the track to clean the track in a convenient way.

[0018] (2) By symmetrically snapping the lower mounting base and the upper mounting base onto the outside of the track, the end faces of the two pairs of support plates are made to fit together. Then, the lower mounting base and the upper mounting base are fixed with bolts, and the two adjacent support plates are fixed at the same time. Then the cleaning pad fits into the outside of the track. Conversely, the mounting base can be removed. Compared with the existing technology, the separate cleaning device is set up, and the two sides of the cleaning device are symmetrical, which makes it convenient to install and disassemble, and facilitates maintenance and replacement in the later stage.

[0024] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-4 The automatic cleaning device for the track of the flexible crane includes a track 1. A lower mounting seat 2 and an upper mounting seat 3 are symmetrically arranged on the outer side of the track 1. Support plates 4 are fixedly connected to both ends of the lower mounting seat 2 and both ends of the upper mounting seat 3. A pair of hydraulic cylinders 6 are fixedly connected to the bottom of the lower mounting seat 2 and the upper mounting seat 3. A moving plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. A positioning mechanism 8 is arranged above the moving plate 7.

[0027] The positioning mechanism 8 includes a drive motor 10, the output end of which is fixedly connected to a gear ring 11, and both sides of the gear ring 11 are meshed with gear bars 12. One end of the gear bar 12 is fixedly connected to a positioning block 13. The positioning mechanism 8 is provided to improve the stability of the moving plate 7.

[0028] See Figure 1 Bolts 5 are threadedly connected to the connection between the lower mounting base 2 and the upper mounting base 3, as well as to the connection between the two adjacent support plates 4. The lower mounting base 2 and the upper mounting base 3 are symmetrically snapped onto the outside of the track 1, so that the end faces of the two pairs of support plates 4 are in contact. Then, the lower mounting base 2 and the upper mounting base 3 are fixed by the bolts 5, and the two adjacent support plates 4 are fixed at the same time.

[0029] See Figure 3The outer end of the support plate 4 is U-shaped, and a cleaning pad 9 is fixedly connected to the inner side of the support plate 4. The cleaning pad 9 is in contact with the outer surface of the track 1. When the mounting seat moves, it drives the support plate 4 to slide on the outside of the track 1, and the cleaning pad 9 cleans the track 1.

[0030] See Figure 2 The drive motor 10 is located at the bottom of the movable plate 7 and is fixedly connected to the movable plate 7. The two racks 12 are arranged in opposite directions. When the drive motor 10 is started, it drives the gear ring 11 to rotate.

[0031] See Figure 4 Both the toothed ring 11 and the toothed rod 12 are located inside the moving plate 7. The toothed ring 11 is movably connected to the moving plate 7, and the toothed rod 12 is slidably connected to the moving plate 7. The rotation of the toothed ring 11 engages with the two toothed rods 12, causing the two positioning blocks 13 to move synchronously in opposite directions.

[0032] See Figure 4 The track 1 has grooves on both sides, and the positioning block 13 is adapted to the grooves. When the positioning block 13 is in contact with the groove on the side of the track 1, the position of the mounting seat is fixed. Conversely, when the positioning block 13 is separated from the groove on the side of the track 1, the mounting seat can be moved.

[0033] In use: The lower mounting base 2 and upper mounting base 3 are symmetrically snapped onto the outside of the track 1, so that the end faces of the two pairs of support plates 4 are in contact. Then, the lower mounting base 2 and upper mounting base 3 are fixed with bolts 5, and the two adjacent support plates 4 are also fixed. The cleaning pad 9 then contacts the outside of the track 1. The drive motor 10, located away from the direction of movement, is started, causing the gear ring 11 to rotate. The rotation of the gear ring 11, in conjunction with the two meshing gears 12, causes the two positioning blocks 13 to move synchronously in opposite directions. When the first pair of positioning blocks 13 contacts the groove on the side of the track 1, the mounting base is fixed to the outside of the track 1. Then, the hydraulic cylinder 6, located near the end of the direction of movement, is started, driving the corresponding moving plate. 7. Move in the direction of movement, and then start the second drive motor 10 to make the second pair of positioning blocks 13 fit into the groove on the side of the track 1. Then, the first drive motor 10 drives the gear ring 11 to rotate in the opposite direction, so that the first pair of positioning blocks 13 separates from the track 1. Then, the hydraulic cylinder 6 near the end of the direction of movement returns oil. Under the return oil pressure, the entire mounting seat moves outside the track 1, driving the support plate 4 to slide outside the track 1. The cleaning pad 9 cleans the track 1. After that, the positions of the two pairs of positioning blocks 13 are adjusted in a cycle. With the corresponding hydraulic cylinder 6, the mounting seat can be adjusted to move along the track 1 to perform a complete cleaning.
