Description

Technical Field

[0001] This utility model relates to an accessory for a pipe cleaning machine, specifically a wheel assembly that facilitates the replacement of the wheels on the pipe cleaning machine. Background Technology

[0002] Pipe cleaning machines are specialized tools used for cleaning pipes. Due to their heavy weight, manual handling is extremely labor-intensive. Therefore, these machines are often equipped with transport tools such as carts or trolleys. These tools typically include a frame and wheels. However, in older buildings, the wheels of these carts are easily damaged when transported up and down stairwells due to frequent impacts with the steps. Damaged carts require immediate replacement to avoid disrupting the operator's work. Currently, the assembly structure and components between the wheels and the frame are quite complex, making wheel replacement inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable wheel assembly for a pipe dredging machine. The technical problem to be solved is to provide a wheel assembly that is easy to replace wheels, making it convenient for operators to replace them.

[0004] A detachable wheel assembly for a pipe cleaning machine includes a connecting rod, two wheels, a first fixing pin, and a second fixing pin. The connecting rod has notches at both ends and mounting holes at the notches. The two ends of the connecting rod are fixed to the notches and mounting holes by the first fixing pin and the second fixing pin, respectively. Each of the two wheels is equipped with a second fixing pin to cooperate with the wheel and fix it to a frame for placing the pipe cleaning machine. The two wheels are respectively fixed to the two ends of the connecting rod.

[0005] The connecting rod is a hollow cylindrical tube.

[0006] The gap is stepped in shape.

[0007] Each side of the wheel is provided with a shim, one of which abuts against the frame and the other abuts against the end of the connecting rod.

[0008] The overall size of the first fixing pin is smaller than that of the second fixing pin.

[0009] The length of the first fixing pin is less than the length of the second fixing pin.

[0010] Both the first fixing pin and the second fixing pin are T-shaped fixing pin structures.

[0011] The beneficial effects of this utility model are: by designing a notch at the end of the connecting rod, this utility model facilitates flexible fixing with the second fixing pin via the first fixing pin. When replacement is required, it is only necessary to remove the first fixing pin and replace it with a new wheel, thereby simplifying the current replacement structure and operation, and greatly improving replacement efficiency and maintenance convenience.

[0025] Please refer to Figures 1 to 5 The figure shows a detachable wheel assembly for a pipe cleaning machine, which is used as a tool to accompany the pipe cleaning machine 7, thereby facilitating the use of the pipe cleaning machine 7.

[0026] The detachable wheel assembly shown in the diagram features a connecting rod 1, two wheels 2, two first fixing pins 3, and two second fixing pins 4. The connecting rod 1 serves as a supporting and fixing component between the two wheels 2. The wheels 2 are used for the movement of the frame 6. The first fixing pins 3 secure the connecting rod 1 to the second fixing pins 4, and the second fixing pins 4 secure the wheels 2 to the frame 6. In practical applications, the number, specific shape, and mating structure and relationships of these components can be adjusted as needed.

[0027] In the embodiment shown in the figure, the connecting rod 1 is a hollow cylindrical component, which facilitates procurement and assembly. The connecting rod 1 undergoes material removal processing at both ends to form notches 11, facilitating the placement of the end portion of the second fixing pin 4. These notches 11, as shown in the figure, have a stepped structure. The connecting rod 1 is placed laterally between the two wheels 2. To facilitate the installation of the connecting rod 1 onto the second fixing pin 4, holes are drilled at corresponding positions on the connecting rod 1 to form mounting holes 12. The first fixing pin 3 passes through these holes and is inserted into the corresponding mounting hole 12 of the second fixing pin 4, thereby achieving mutual fixation between the first fixing pin 3, the second fixing pin 4, and the connecting rod 1. In practical applications, the number, specific shape, and material of the connecting rod 1 can be adjusted as needed.

[0028] In the diagram, both the first fixing pin 3 and the second fixing pin 4 are conventional fixing pin structures, specifically T-shaped fixing pin structures. The overall size of the first fixing pin 3 is smaller than that of the second fixing pin 4, and its length is also shorter. As shown, the first fixing pin 3 is installed longitudinally, while the second fixing pin 4 is installed laterally. The former mounts the connecting rod 1 onto the second fixing pin 4, while the latter mounts the wheel 2 onto the frame 6. In practical applications, the number, shape, and material of the two fixing pins can be adjusted as needed.

[0029] The wheel 2 in the figure is a conventional wheel 2 structure, with a gasket 5 on each side. That is, one gasket 5 abuts against the frame 6, and the other gasket 5 abuts against the end of the connecting rod 1, thus avoiding tight installation of the components. The frame 6 in the figure is a conventional frame 6 structure, on which the pipe cleaning machine 7 is placed.
