Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0019] Example:

[0020] like Figure 1-Figure 3 As shown, this embodiment provides a self-climbing clamp device, including a first semicircular clamp 1 and a second semicircular clamp 2 that are arranged in cooperation. After the first semicircular clamp 1 and the second semicircular clamp 2 are connected to each other, they can be clamped outside the pier, and then when the first semicircular clamp 1 and the second semicircular clamp 2 are cooperated to clamp the temporary fixing point of the pier, the subsequent bridge cap beam construction operation can be carried out.

[0021] Specifically, both ends of the first semicircular clamp 1 are connected to the first fastening plate 101, and both ends of the second semicircular clamp 2 are connected to the second fastening plate 201. A first connecting member 3 is installed on the side of the first fastening plate 101 away from the second fastening plate 201. The first connecting member 3 can be directly installed on the first fastening plate 101 according to actual needs, or indirectly installed on the arc-shaped clamp body of the first semicircular clamp 1 to ensure the stability of the first connecting member 3. A second connecting member 4 threadedly connected to the first connecting member 3 is installed on the side of the second fastening plate 201 away from the first fastening plate 101. A torque motor 5 that drives the second connecting member 4 to be threadedly connected to the first connecting member 3 is also installed on one side of the second fastening plate 201. The second connecting member 4 is connected to the motor shaft of the torque motor 5. 5 can be indirectly installed on the second fastening plate 201 according to needs, or can be directly or indirectly installed on the arc-shaped hoop body of the second semicircular hoop 2, to ensure the stability of the torque motor 5, and thus the torque motor 5 can stably control the second connecting member 4, thereby realizing the threaded connection between the second connecting member 4 and the first connecting member 3, and through the threaded connection between the second connecting member 4 and the first connecting member 3, the first semicircular hoop 1 and the second semicircular hoop 2 can be matched and connected; the first fastening plate 101 and the second fastening plate 201 are both provided with avoidance holes for facilitating the threaded connection between the first connecting member 3 and the second connecting member 4, which does not affect the connection between the second connecting member 4 and the first connecting member 3, nor does it affect the final close fit between the first fastening plate 101 and the second fastening plate 201.

[0022] Furthermore, a plurality of first vertical telescopic machines 6 are evenly installed on the outside of the arc-shaped hoop body of the first semicircular hoop 1, and the telescopic rod of each first vertical telescopic machine 6 is connected to a first horizontal telescopic machine 7 located below the first semicircular hoop 1, and the extension direction of each first horizontal telescopic machine 7 is perpendicular to the central axis of the first semicircular hoop 1. When the first horizontal telescopic machine 7 is in a retracted state, the first horizontal telescopic machine 7 does not contact the pier, and when the first horizontal telescopic machine 7 is extended, it can stably abut against the outer surface of the pier; a plurality of second vertical telescopic machines 8 are evenly installed on the outside of the arc-shaped hoop body of the second semicircular hoop 2, and the telescopic rod of each second vertical telescopic machine 8 is connected to a second horizontal telescopic machine 9 located below the second semicircular hoop 2, and the extension direction of each second horizontal telescopic machine 9 is perpendicular to the central axis of the second semicircular hoop 2. When the second horizontal telescopic machine 9 is in a retracted state, the second horizontal telescopic machine 9 does not contact the pier, and when the second horizontal telescopic machine 9 is extended, it can stably abut against the outer surface of the pier.

An auxiliary torque motor can also be fixed on the side of the first fastening plate 101 away from the second fastening plate 201. The auxiliary torque motor is connected to the first connecting member 3, so that the first connecting member 3 and the second connecting member 4 can rotate in opposite directions, and a threaded connection between the two can also be achieved.

[0024] The workflow of the present invention is as follows:

[0025] 1. Set the first semicircular hoop 1 and the second semicircular hoop 2 on the ground on both sides of the pier respectively;

[0026] 2. Start the torque motor 5, and use the torque motor 5 to control the second connecting member 4 to connect with the first connecting member 3 for temporary fixation, so that the first semicircular clamp 1 and the second semicircular clamp 2 maintain a gap of about 1-3 cm with the pier column;

[0027] 3. All first vertical telescopic machines 6 are divided into the first part and the second part in advance, and the first horizontal telescopic machine 7 is divided into the first part and the second part corresponding to the first vertical telescopic machine 6; all second vertical telescopic machines 8 are also divided into the first part and the second part, and the second horizontal telescopic machine 9 is divided into the first part and the second part corresponding to the second vertical telescopic machine 8, wherein the first vertical telescopic machine 6 of the first part is symmetrically arranged with the second vertical telescopic machine 8 of the first part, and the first vertical telescopic machine 6 of the second part is also symmetrically arranged with the second vertical telescopic machine 8 of the second part; when working, the first horizontal telescopic machine 7 of the first part and the second horizontal telescopic machine 9 of the first part are first started, both of which are close to the pier, and then the first vertical telescopic machine of the first part is started 6 and the second vertical telescopic machine 8 of the first part, so that the first semicircular hoop 1 and the second semicircular hoop 2 can achieve the first climbing; then the first horizontal telescopic machine 7 of the second part is started, and the second horizontal telescopic machine 9 of the second part is pressed against the pier, and then the first horizontal telescopic machine 7 of the first part and the second horizontal telescopic machine 9 of the first part are retracted, and the first vertical telescopic machine 6 of the first part and the second vertical telescopic machine 8 of the first part are also retracted, and then the first vertical telescopic machine 6 of the second part and the second vertical telescopic machine 8 of the second part are started again, so that the first semicircular hoop 1 and the second semicircular hoop 2 can achieve the second climbing, and so on and so forth, until the first semicircular hoop 1 and the second semicircular hoop 2 climb to the designated temporary fixed position;

[0028] 4. Start the torque motor 5 to further connect the second connecting member 4 with the first connecting member 3, and at the same time gradually retract the first horizontal telescopic machine 7 and the second horizontal telescopic machine 9 until the first semicircular clamp 1 and the second semicircular clamp 2 are stably clamped on the pier.

[0029] When the first semicircular clamp 1 and the second semicircular clamp 2 are climbing, the automatic climbing can be achieved by utilizing the cooperation between the first vertical telescopic machine 6, the first horizontal telescopic machine 7, the second vertical telescopic machine 8 and the second horizontal telescopic machine 9, and then the torque motor 5 is utilized to control the second connecting member 4 to be threadedly connected with the first connecting member 3, so as to realize automatic locking of the pier column. The whole process does not require the participation of personnel, thus reducing the safety risks of the operating personnel and the use of cranes and hoists. At the same time, it is not easy to damage the appearance of the pier column, thus reducing the later repair work. Moreover, the torque requirements of the clamp bolts can be accurately grasped through the automatic control of the torque motor 5.
