[0028] Please see Figures 1 to 5 , Figure 1 This is a structural schematic diagram of the counter-pressure three-leaf clamping device of this utility model. Figure 2 for Figure 1 Schematic diagram of Part A, Figure 3 for Figure 1 AA section view, Figure 4 This is a schematic diagram of the positioning and counter-jacking jack in the counter-pressure type three-leaf clamping device of this utility model. Figure 5 This is a schematic diagram showing the connection between the first and second arc modules in the counter-pressure three-leaf clamping device of this utility model. A counter-pressure three-leaf clamping device includes a U-shaped platform 1, a first arc module 2, and two second arc modules 3. The U-shaped platform 1 includes two arm beams 11 and a middle beam 12 connecting the two arm beams 11. The first arc module 2 is located between the first and second arm beams 11 and is mounted on the middle beam 12. The two second arc modules 3 are respectively hinged to both ends of the first arc module 2. The two arm beams 11 correspond one-to-one with the two second arc modules 3.

The second arc modules 3 are provided with first through holes 33 for the corresponding positioning counter-pressure jacks 5 on the arm beams 11 to pass through.

[0029] The two second arc modules 3 of the utility model have a gap, the gap is greater than the width of the middle beam, then the positioning counter-jack 5 is first passed through the second arc module 3 and abuts against the cylindrical pier 9, positioning effect is achieved, and the hoop device has better contact with the surface of the cylindrical pier 9 from the beginning, effectively ensuring the working boundary conditions of the hoop device and the cylindrical pier 9, then the counter-jack 4 and the arm beam 11 of the U-shaped platform 1 are used to realize counter-pressure on the second arc module 3, so that the hoop device is fixed on the cylindrical pier 9, and the open hoop is realized, and since the two second arc modules 3 have the gap greater than the width of the middle beam, the middle beam can pass through the gap between the two second arc modules 3, so that the hoop device can smoothly pass through the middle beam obstacle structure of the cylindrical pier 9, so that the hoop device can be applied to the cylindrical pier 9 with the middle beam design. Further, the positioning counter-jack 5 combined with the counter-jack 4 can increase the tangential component force, so that the effective pulling force of the hoop device is greater, and the hoop device can more stably hold the cylindrical pier 9.

[0030] In an embodiment, the counter-jack 4 and the positioning counter-jack 5 are inclinedly arranged on the arm beam 11, wherein the counter-jack 4 is inclined to the side away from the middle beam 12 at the end away from the arm beam 11, and the positioning counter-jack 5 is inclined to the side close to the middle beam 12 at the end away from the arm beam 11. The positioning counter-jack 5 and the counter-jack 4 have a certain angle, and are designed in opposite directions, so that the positioning counter-jack 5 exerts force backward, drives the U-shaped platform 1 to be close to the cylindrical pier 9, and makes the first arc module 2 closely adhere to the cylindrical pier 9, so as to achieve the positioning and backward counter-jacking effect, and the counter-jack 4 exerts force forward, counter-presses the second arc module 3 on the surface of the cylindrical pier 9, and generates a component force to push the U-shaped platform 1 backward, so that the internal force of the hoop device is balanced. In an embodiment, the counter-jacks 4 are arranged in the vertical direction, and the positioning counter-jacks 5 are arranged in the vertical direction. This arrangement can make the hoop device hold the cylindrical pier 9 more stably.

[0031] In an embodiment, the second arc module 3 is provided with a plurality of counter-flanges 31 at the end away from the first arc module 2, and the plurality of counter-flanges 31 are hinged to the plurality of counter-jacks 4.

[0032] In an embodiment, the counter-jack 4 is provided with an ear plate 41 at the end away from the second arc module 3, and the ear plate 41 is hinged to the arm beam 11. The counter-jack 4 is hinged to the arm beam 11 through the ear plate 41, so as to facilitate the installation of the counter-jack 4 on the U-shaped platform 1.

[0033] In an embodiment, the first circular arc module 2 is internally provided with a first inner lining plate 21, the second circular arc module 3 is internally provided with a second inner lining plate 32, and the second inner lining plate 32 is provided with a second through hole 34 corresponding to the position of the first through hole 33. The first inner lining plate 21 and the second inner lining plate 32 can be made of a relatively hard plastic plate with elastic function, so as to avoid the direct contact between the first circular arc module 2 and the second circular arc module 3 and the surface of the cylindrical pier 9, and effectively protect the surface of the cylindrical pier 9. The positioning counter-jack 5 is in abutment with the cylindrical pier 9 after penetrating through the corresponding first through hole 33 and second through hole 34.

[0034] Please refer to Figure 6 and Figure 7 , Figure 6 Fig. 3 is a structural schematic view of a bracket assembly in the reverse pressure type three-leafed hoop device of the present application, Figure 7 Fig. 4 is a side view of the bracket assembly in the reverse pressure type three-leafed hoop device of the present application. In an embodiment, the first circular arc module 2 is connected with the middle beam 12 through the bracket assembly 6. This arrangement facilitates the installation of the first circular arc module 2 on the U-shaped platform 1. In an embodiment, the bracket assembly 6 comprises a first bracket 61 arranged on the middle beam 12 and a second bracket 62 arranged on the first circular arc module 2, and the first bracket 61 and the second bracket 62 are connected. This arrangement enables the first circular arc module 2 to be more stably installed on the middle beam 12.

[0035] Please refer to Figure 8 , Figure 8 Fig. 5 is a schematic view of a third bracket and a fourth bracket in the reverse pressure type three-leafed hoop device of the present application. In an embodiment, the second circular arc module 3 is provided with a third bracket 7 at one end away from the first circular arc module 2, and the arm beam 11 is provided with two fourth brackets 8 for abutting against the upper and lower ends of the third bracket 7, respectively. The two fourth brackets 8 are located above and below the third bracket 7, respectively. When the reverse pressure type three-leafed hoop device of the present application is converted to bear a force, the third bracket 7 and the fourth bracket 8 support each other, so that the climbing device adopting the reverse pressure type three-leafed hoop device of the present application can be more stably clamped on the cylindrical pier 9. For example, when the reverse pressure type three-leafed hoop device of the present application clamps the cylindrical pier 9, the third bracket 7 supports the fourth bracket 8, thereby supporting the corresponding U-shaped platform 1. When the reverse pressure type three-leafed hoop device of the present application loosens the cylindrical pier 9, the fourth bracket 8 supports the corresponding third bracket 7.

[0036] The working principle of the reverse pressure type three-leafed hoop device of the present application is briefly described as follows:

[0037] The positioning counter-jack 5 is controlled to extend out, and after the positioning counter-jack 5 passes through the first through hole 33 of the corresponding second arc module 3 and the second through hole 34 of the second inner lining plate 32, the positioning counter-jack 5 directly supports the cylindrical pier 9. In this process, since the positioning counter-jack 5 is inclined to the side close to the intermediate beam 12, as the positioning counter-jack 5 continuously extends out, the U-shaped platform 1 is driven to move close to the cylindrical pier 9 in the opposite direction, so that the first arc module 2 closely adheres to the cylindrical pier 9, thereby achieving the positioning and rear counter-supporting effect, and the hoop device has better contact with the surface of the cylindrical pier 9 from the beginning, effectively ensuring the working boundary conditions of the hoop device and the cylindrical pier 9. Then the counter-pressure jack 4 is controlled to extend out, and the two second arc modules 3 are counter-pressed on the surface of the cylindrical pier 9, so as to generate friction and circumferential tension, thereby making the hoop device tightly hold the cylindrical pier 9. Since the counter-pressure jack 4 is inclined to the side away from the intermediate beam 12, in addition to tightly pressing the second arc module 3 on the surface of the cylindrical pier 9, a component force is also generated to push the U-shaped platform 1 backward. At this time, since the positioning counter-jack 5 has a counter-supporting effect, the forward and backward component forces generated by the counter-pressure jack 4 and the positioning counter-jack 5 are balanced, that is, the internal force of the U-shaped platform is balanced.

[0038] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application, which does not deviate from the technical solution of the present application, still belongs to the scope of the technical solution of the present application.
