DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-Figure 2 As shown, the embodiment of the utility model proposes a device for clearing blockage of a prestressed pipe 1 of a continuous bridge, which is installed on the prestressed pipe 1. The prestressed pipe 1 has axial and radial directions. The device comprises:

[0020] A mounting seat 2 is arranged along the axial direction of the prestressed pipe 1, and the mounting seat 2 is provided with a drill bit 3;

[0021] Two traveling assemblies are mirror-imaged and arranged in the radial direction of the prestressed pipe 1. Each traveling assembly includes a driving gear 4, and a first traveling gear 5 and a second traveling gear 6 arranged alternately. The driving gear 4 is rotatably arranged on the mounting seat 2. The first traveling gear 5 is rotatably engaged with the driving gear 4, and the second traveling gear 6 is engaged with the prestressed pipe 1.

[0022] The two adjustment assemblies are respectively connected to the first traveling gear 5 and the second traveling gear 6 so as to make the first traveling gear 5 and the second traveling gear 6 contact or separate from the prestressed pipe 1 under the action of external force.

[0023] In this embodiment, the prestressed pipe 1 adopts a bellows. In order to facilitate the cleaning of the blocked part of the prestressed pipe, a clearing device is provided inside the prestressed pipe 1. The clearing device includes a mounting seat 2 arranged along the axial direction of the prestressed pipe 1, and a drill bit 3 is provided at the front end of the mounting seat 2 for breaking the blockage in the pipe. Two traveling components are symmetrically provided in the radial direction of the prestressed pipe 1. The traveling component includes a driving gear 4 and a first traveling gear 5 and a second traveling gear 6 arranged alternately. The driving gear 4 is rotatably arranged on the mounting seat 2. The first traveling gear 5 is meshed with the driving gear 4 at the lower end of the inner wall of the prestressed pipe 1 as a driving source. The second traveling gear 6 is meshed with the upper end of the inner wall of the prestressed pipe 1. Under the action of external force, the positive rotation of the driving gear 4 causes the first traveling gear 5 to reverse and mesh with the corrugation of the inner wall of the prestressed pipe 1. The second traveling gear 6 is idle, and its rotation direction is consistent with the rotation direction of the first traveling gear 5. When the second traveling gear 6 is meshed with the inner wall of the prestressed pipe 1, it cooperates with the rotation of the first traveling gear 5. At the same time When the first gear 5 and the second gear 6 are engaged with the inner wall of the prestressed pipe 1, the blockage clearing device is advanced. On the contrary, the driving gear 4 is reversed to withdraw the blockage clearing device from the prestressed pipe 1. On the other hand, in order to make the first traveling gear 5 and the second traveling gear 6 fit the inner wall of the prestressed pipe 1, an adjusting component is provided on the mounting seat 2, which is respectively connected to the first traveling gear 5 and the second traveling gear 6, so that the first traveling gear 5 and the second traveling gear 6 can be abutted or separated from the prestressed pipe 1 under the action of external force. The two traveling components set in mirror image are adjusted synchronously, so that the blockage clearing device can always be consistent with the center line of the prestressed pipe 1, avoiding deviation when the drill bit 3 is subjected to inconsistent working force; the adjusting component enables the blockage clearing device to flexibly adjust the contact state with the inner wall of the prestressed pipe 1 as needed, that is, the meshing state of the first traveling gear 5, the second traveling gear 6 and the inner wall of the prestressed pipe 1 can be adjusted according to the diameter of the prestressed pipe 1, which not only ensures stability and cleaning effect during advancement, but also ensures convenience and versatility when adjusting the position.

[0024] The adjustment assembly includes a plurality of adjustment rods 7 and sliders 8. The sliders 8 are slidably arranged on the mounting seat 2. The proximal ends of the adjustment rods 7 are hinged to the sliders 8. The distal ends of the adjustment rods 7 are respectively hinged to the first traveling gear 5 and the second traveling gear 6. When the sliders 8 slide back and forth, the adjustment rods 7 link the first traveling gear 5 and the second traveling gear 6 to abut against or separate from the prestressed pipe 1.

[0025] In this embodiment, in order to facilitate the adjustment of the contact state between the first traveling gear 5, the second traveling gear 6 and the inner wall of the prestressed pipe 1, the adjusting member includes two adjusting rods 7 and a slider 8. The slider 8 is slidably provided with a mounting seat 2. The proximal end of the adjusting rod 7 is hinged to the slider 8, and the distal end of the adjusting rod 7 is hinged to the first traveling gear 5 and the second traveling gear 6. The slider 8 slides forward relative to the mounting seat 2. The inclination of the adjusting rod 7 makes the contact between the first traveling gear 5, the second traveling gear 6 and the driving gear 4 closer. When the driving gear 4 rotates, the power is transmitted to the second traveling gear 6 through the first traveling gear 5, so that the second traveling gear 6 generates sufficient friction on the inner wall of the pipe, thereby pushing the entire clearing device forward; when the position of the first traveling gear 5 and the second traveling gear 6 needs to be adjusted, the slider 8 slides backward relative to the mounting seat 2, and the first traveling gear 5 and the second traveling gear 6 are first separated from the inner wall of the prestressed pipe 1 by the action of the adjusting rod 7. Then, according to the actual diameter of the prestressed pipe 1, the slider 8 slides forward relative to the mounting seat 2, and the first traveling gear 5 and the second traveling gear 6 are respectively abutted against the upper and lower ends of the prestressed pipe 1 through the adjusting rod 7.

[0026] The mounting seat 2 is provided with a bidirectional screw rod 9 , and the slider 8 is slidably arranged on the bidirectional screw rod 9 .

[0027] In this embodiment, the bidirectional screw 9 can provide more precise control. By rotating the bidirectional screw 9, the reciprocating sliding of the two sliders 8 can be precisely adjusted, thereby better controlling the contact degree between the two first travel gears 5 and the two second travel gears 6 and the inner wall of the prestressed pipe 1. Furthermore, the bidirectional screw 9 is rotatably provided with a nut 10.

[0028] The mounting seat 2 is provided with a connected rotating shaft 11 and several mounting frames 12, the driving gear 4 is rotatably arranged on the rotating shaft 11, the first traveling gear 5 and the second traveling gear 6 are respectively rotatably arranged on the mounting frames 12, and the distal end of the adjusting rod 7 is hinged to the mounting frame 12.

[0029] In this embodiment, a rotating shaft 11 is provided on the mounting base 2, and the driving gear 4 is rotatably mounted on the rotating shaft 11. Two mounting frames 12 are provided on the mounting base 2. The two mounting frames 12 are used to support the first traveling gear 5 and the second traveling gear 6. The first traveling gear 5 and the second traveling gear 6 can rotate around the axis on the mounting frame 12. The distal end of the adjusting rod 7 is hinged to the mounting frame 12, so that the adjusting rod 7 can change the angle as the slider 8 slides, thereby changing the position of the first traveling gear 5 and the second traveling gear 6 in a linked manner, so that they abut against or separate from the inner wall of the prestressed pipe 1.

[0030] The mounting bracket 12 includes a connecting section 121 and a rotating section 122 connected in sequence. The connecting section 121 is rotatably hinged to the adjusting rod 7 , and the rotating section 122 is sleeved on the rotating shaft 11 .

[0031] In this embodiment, the connecting section 121 is hinged to the adjusting rod 7. When the adjusting rod 7 changes angle as the slider 8 slides, the connecting section 121 also changes angle accordingly. The connecting section 121 and the adjusting rod 7 are arranged at an angle to form a triangular support structure, which makes the first and second traveling gears 5 and 6 more stable when moving forward. The rotating section 122 is sleeved on the rotating shaft 11 so that it can rotate around the rotating shaft 11. The traveling gears on the mounting frame 12 can rotate as the adjusting rod 7 rotates to change the positions of the first and second traveling gears 5 and 6.

[0032] The traveling assembly further includes two pulleys respectively provided on the two driving gears 4 , and the two pulleys are connected via the belt.

[0033] In this embodiment, the connection between the pulley and the belt (not shown) ensures the synchronous rotation of the two driving gears 4, thereby achieving the synchronous rotation of the first traveling gear 5 and the second traveling gear 6, thereby improving the stability and coordination of the blockage clearing device.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
