[0023] To make the technical problems, technical solutions, and advantages to be solved by the utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments.
[0024] The utility model provides a pipe ramming machine anti-tipping device, as Figures 1-5 shown, which includes an outer sliding box connection component 1, an inner sliding box slider component 2, and a jaw component 3. The outer sliding box connection component 1 is used to be welded to the designated position of the pipe ramming machine unit. A sliding track 4 is arranged on the inner side wall of the box body of the outer sliding box connection component 1. The inner sliding box slider component 2 is arranged inside the outer sliding box connection component 1 and can slide along the sliding track 4.
[0025] The jaw assembly 3 includes two symmetrically arranged jaw blocks 5. Each jaw block 5 is connected to a pipe-rolling oil cylinder 6 that drives the jaw block 5, and the pipe-rolling oil cylinder 6 is arranged on the inner sliding box slider assembly 2.
[0026] A first limiting component 7 for preventing the inner sliding box slider assembly 2 from sliding out of the sliding track 4 is arranged at the outer end of the sliding track 4, and a second limiting component 8 for preventing the inner sliding box slider assembly 1 from sliding into the sliding track 4 is arranged at the inner end of the sliding track 4.
[0027] Due to the lack of a regulating oil cylinder for protection in the prior art, during the moving state, the stroke of the inner sliding box assembly is not restricted and it will tilt forward infinitely. In view of this shortcoming, the present utility model chooses to add a second limiting component to prevent losses caused by tilting, thereby increasing the service life of the pipe-rolling machine and improving the stability and reliability of the product itself. And a first limiting component is provided to prevent the inner sliding box assembly from sliding out of the sliding track infinitely, causing risks such as damage and paralysis of the pipe-rolling machine.
[0028] The present utility model does not limit the specific structural forms of the first limiting component 7 and the second limiting component 8, as long as they can play a limiting role. In one example, the first limiting component 7 is a stop block or a plug pin, and the stop block or the plug pin is arranged on the inner side wall of the outer sliding box connecting component 1. The second limiting component 8 is a limiting pin shaft, and the limiting pin shaft is arranged vertically and has a set distance from the inner side wall of the outer sliding box connecting component 1.
[0029] As an improvement of the present utility model, an adjusting rod assembly 9 is arranged between the two aforementioned pipe-rolling oil cylinders 6. The two ends of the adjusting rod assembly 9 are respectively connected to the inner sliding box slider assembly 2 and the jaw assembly 3. The adjusting rod assembly 9 is used to adjust the levelness of the jaw assembly 3.
[0030] During the transportation process of the pipe-rolling machine, there are problems such as road bumps and rough areas, resulting in tilting. The present utility model is detachably provided with a transportation adjusting component 10 on the sliding track 4 to prevent the inner sliding box slider assembly 2 from tilting during transportation. Specifically, the transportation adjusting component 10 is a horizontally arranged rod, and the rod is detachably arranged on the side wall of the outer sliding box connecting component 1. The transportation adjusting component 10 is arranged between the first limiting component 7 and the second limiting component 8.
[0031] During the factory production and assembly of the equipment, the stop block or the plug pin and the limiting pin shaft are assembled to the designated positions. When transporting after production is completed, the transportation adjusting component is installed at the designated position. After arriving at the designated location, the transportation adjusting component is removed during the working process. After the equipment stops working, the transportation adjusting component is installed at the designated position again.
[0032] The aforementioned outer sliding box connecting component 1 and the jaw assembly 3 are arranged on the chassis assembly 11.
[0033] In summary, the present utility model adds components such as the first limiting component, the second limiting component, and the transportation adjustment component, thereby reducing multiple large components such as the adjustment oil cylinder and the adjustment cross joint, reducing costs, saving raw materials and assembly processes. During transportation and in the working state, the stroke of the inner sliding box component is restricted, preventing it from sliding out of the track and causing tipping, ensuring the safety and stability of the equipment, making the equipment more refined and accurate, and increasing the service life of the pipe ramming machine.
[0034] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
