Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a five-leaf clamping device. Background Technology

[0002] In the construction of tall structures, especially in the construction of high bridge piers, hoisting operations are difficult and pose significant safety risks. Therefore, climbing devices are often used. These devices employ two clamps, one upper and one lower, to grip the pier and transport the necessary equipment or facilities for the cap beam construction to the upper part of the pier. Specifically, clamps are installed on the pier, and the maximum static friction generated by the clamps against the pier overcomes the weight of the equipment or facilities. Each pier has two clamps, and the climbing is achieved by alternately tightening and loosening the pier. However, existing bridge cylindrical piers are generally divided into two types: those with a central tie beam and those without. The clamps for the climbing devices are designed separately for these two types of piers, making them incompatible and resulting in significant limitations and resource waste. Utility Model Content

[0003] The purpose of this utility model is to provide a five-leaf clamp device that can be used for both bridge piers with and without a central tie beam, solving the problem of the significant limitations of existing clamps and the resulting waste of resources.

[0004] This utility model is achieved through the following technical solution:

[0005] A five-leaf clamping device includes a U-shaped platform, a first arc module, two second arc modules, and two third arc modules. The U-shaped platform includes two arm beams and a middle beam connecting the two arm beams. The first arc module is located between the first and second arm beams and is mounted on the middle beam. The two second arc modules are respectively hinged to both ends of the first arc module. The two third arc modules are respectively hinged to the ends of the two second arc modules away from the first arc module. Several pull-and-pull jacks are detachably connected between the two third arc modules. The two arm beams correspond one-to-one with the two second arc modules, and several counter-pressure jacks are detachably connected between the arm beams and the corresponding second arc modules.

[0006] Furthermore, a mounting plate is provided on the end of the third arc module away from the second arc module, and the pull-open jack is detachably connected to the mounting plates of the two third arc modules.

[0007] Furthermore, the end of the counter-pressure jack furthest from the arm beam tilts towards the side furthest from the intermediate beam.

[0008] Furthermore, the second arc module is provided with several counter-pressure flanges at the end away from the first arc module. The several counter-pressure flanges are detachably connected to several counter-pressure jacks, and the counter-pressure jacks are detachably connected to the arm beam through ear plates.

[0009] Furthermore, the inner sides of the first arc module, the second arc module, and the third arc module are all provided with inner lining plates.

[0010] Furthermore, the first arc module is connected to the intermediate beam via a corbel assembly.

[0011] Furthermore, the bracket assembly includes a first bracket disposed on the intermediate beam and a second bracket disposed on the first arc module, the first bracket and the second bracket being connected.

[0012] Furthermore, a third bracket is provided on the outer end of the second arc module away from the first arc module, and two fourth brackets are provided on the arm beam for abutting against the upper and lower ends of the third bracket.

[0013] Compared to existing technologies, the advantages of this invention are as follows: When used on piers with a central tie beam, the pull-opening jacks on the two third arc modules are removed, and the two third arc modules are opened. A counter-pressure jack is then used to tighten the clamp onto the pier. The gap between the two second arc modules allows the five-leaf clamp device to pass smoothly through the central tie beam obstacle structure on the pier, thus making it suitable for piers with a central tie beam design. When used on piers without a central tie beam, the counter-pressure jacks can be removed, and the pull-opening jacks can be used to pull the two third arc modules together to tighten the clamp onto the pier. Therefore, this invention can be applied to both piers with and without a central tie beam, solving the problem of significant limitations and resource waste associated with existing clamps.

[0027] Please see Figures 1 to 4 , Figure 1 This is a structural schematic diagram of the five-leaf clamping device of this utility model. Figure 2 This is a schematic diagram illustrating the use of the five-leaf clamp device of this utility model on a bridge pier with a central tie beam. Figure 3 This is a schematic diagram illustrating the use of the five-leaf clamp device of this utility model on a bridge pier without a central tie beam. Figure 4 This is a schematic diagram showing the connection of the first, second, and third arc modules in the five-leaf clamping device of this utility model. A five-leaf clamping device includes a U-shaped platform 1, a first arc module 2, two second arc modules 3, and two third arc modules 4. 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 third arc modules 4 are respectively hinged to the ends of the two second arc modules 3 away from the first arc module 2. Several pulling jacks 5 are detachably connected between the two third arc modules 4. The two arm beams 11 correspond one-to-one with the two second arc modules 3, and several counter-pressure jacks 6 are detachably connected between the arm beams 11 and their corresponding second arc modules 3.

[0028] When this five-leaf clamping device is used on a bridge pier 9 with a central tie beam, the pull-opening jacks 5 on the two third arc modules 4 are removed, and the two third arc modules 4 are opened. Then, the second arc modules 3 are counter-pressed by the counter-pressure jacks 6 and the arm beam 11 of the U-shaped platform 1, pressing the two second arc modules 3 against the surface of the bridge pier 9, generating friction and circumferential tension, thus allowing the five-leaf clamping device to clamp onto the bridge pier 9. At this time, there is a gap between the two second arc modules 3, realizing an open clamping design. The central tie beam can pass through the gap between the two second arc modules 3, allowing the five-leaf clamping device to pass smoothly through the central tie beam obstacle structure of the bridge pier 9, thus making the five-leaf clamping device suitable for bridge piers 9 with a central tie beam design. When used on piers 9 without a central tie beam, the five-leaf clamping device of this utility model can remove the counter-pressure jack 6 and pull the two third arc modules 4 together by the pull-close jack 5. At this time, the first arc module 2, the second arc module 3, and the third arc module 4 are pressed tightly against the surface of the pier 9, generating friction. This causes the circular structure formed by the first arc module 2, the two second arc modules 3, and the two third arc modules 4 to clamp onto the pier 9, thus making the five-leaf clamping device suitable for piers 9 without a central tie beam. Therefore, the five-leaf clamping device of this utility model can be used for both piers 9 with and without a central tie beam, solving the problem of the significant limitations and resource waste caused by existing clamps.

[0029] In one embodiment, a mounting plate 41 is provided on the end of the third arc module 4 away from the second arc module 3, and the pull-opening jack 5 is detachably connected to the mounting plates 41 of the two third arc modules 4. This arrangement facilitates the detachable installation of the pull-opening jack 5 on the two third arc modules 4. Specifically, the top body of the pull-opening jack 5 can be bolted to either mounting plate 41. The mounting plate 41 has through holes, and the top rod of the pull-opening jack 5 has threads. The top rod of the pull-opening jack 5 passes through the through holes of the two mounting plates 41 in sequence and is threaded to a fixing nut. When the five-leaf clamping device needs to clamp the pier 9, the pull-opening jack 5 retracts, causing one mounting plate 41 to abut against the top body of the pull-opening jack 5, and the other mounting plate 41 to abut against the fixing nut. The fixing nut and the top body of the pull-opening jack clamp the two mounting plates 41, thereby clamping the circular structure formed by the first arc module 2, the two second arc modules 3, and the two third arc modules 4 onto the pier 9.

[0030] In one embodiment, the end of the counter-pressure jack 6 furthest from the arm beam 11 is tilted away from the intermediate beam 12. The counter-pressure jack 6 applies force forward, pressing the second arc module 3 against the surface of the pier 9, allowing the five-leaf clamp device to more firmly grip the pier 9. In one embodiment, several counter-pressure jacks 6 are spaced apart vertically. This arrangement allows the five-leaf clamp device to grip the pier 9 more smoothly.

[0031] In one embodiment, the second arc module 3, at its end away from the first arc module 2, is provided with a plurality of counter-pressure flanges 31. These counter-pressure flanges 31 are detachably connected to a plurality of counter-pressure jacks 6, which are detachably connected to the arm beam 11 via ear plates 61. The counter-pressure flanges 31 on the second arc module 3 for detachable connection to the counter-pressure jacks 6, and the ear plates 61 on the counter-pressure jacks 6 for detachable connection to the arm beam 11, facilitate the detachable installation of the counter-pressure jacks 6 between the arm beam 11 and the corresponding second arc module 3. Furthermore, the detachable connection between the ear plates 61 of the counter-pressure jacks 6 and the arm beam 11 is a pin connection, as is the detachable connection between the counter-pressure jacks 6 and the counter-pressure flanges 31. This allows the counter-pressure jacks 6 to rotate on the arm beam 11 and the counter-pressure flanges 31, thereby pressing the second arc module 3 against the surface of the pier 9.

[0032] In one embodiment, the inner sides of the first arc module 2, the second arc module 3, and the third arc module 4 are all provided with inner lining plates 7. The inner lining plates 7 can be made of relatively hard plastic sheets with elasticity to prevent the first arc module 2, the second arc module 3, and the third arc module 4 from directly contacting the surface of the pier 9, thereby effectively protecting the surface of the pier 9.

[0033] In one embodiment, the first arc module 2 is connected to the intermediate beam 12 via a bracket assembly 8. This arrangement facilitates the installation of the first arc module 2 on the U-shaped platform 1. In one embodiment, the bracket assembly 8 includes a first bracket 81 disposed on the intermediate beam 12 and a second bracket 82 disposed on the first arc module 2, the first bracket 81 and the second bracket 82 being connected. This arrangement allows the first arc module 2 to be more securely installed on the intermediate beam 12.

[0034] In one embodiment, a third bracket 32 ​​is provided on the outer end of the second arc module 3 away from the first arc module 2, and two fourth brackets 13 are provided on the arm beam 11 for abutting against the upper and lower ends of the third bracket 32. The two fourth brackets 13 are located above and below the third bracket 32, respectively. When the five-leaf clamp device of this utility model changes the force, the third bracket 32 ​​and the fourth bracket 13 provide mutual support, so that the climbing device using the five-leaf clamp device of this utility model can more stably clamp onto the pier 9. For example, when the five-leaf clamp device clamps the pier 9, the third bracket 32 ​​supports the fourth bracket 13, thereby supporting the corresponding U-shaped platform 1. When the five-leaf clamp device releases the pier 9, the fourth bracket 13 supports the corresponding third bracket 32.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
