Description

Technical Field

[0001] This application belongs to the technical field of bridge erection or assembly, and particularly relates to a climbing device for cap beam construction and its assembly and disassembly method. Background Technology

[0002] In the construction of bridge cap beams, two clamps, one upper and one lower, can be used to transport the relevant facilities or equipment to the upper part of the pier. Specifically, clamps are installed on the pier column, and the maximum static friction generated by clamping the clamps to the pier column is used to overcome the weight of the facilities or equipment. Two clamps are installed on each pier, and a power device is installed between the two clamps to change the distance between them. Step-by-step climbing is achieved by alternately tightening and loosening the pier and by pushing and pulling the power device.

[0003] On the one hand, it is necessary to transport the relevant facilities or equipment for the construction of the cap beam, and on the other hand, it is necessary to connect the power unit with the clamp. Therefore, it is necessary to install a load-bearing frame on the clamp.

[0004] To facilitate the installation of the clamps into the cavity of the support frame, sufficient clearance needs to be maintained between the clamps and the support frame in the vertical direction. When the clamps are released, they will fall freely from the upper plane of the support frame's inner cavity to the lower plane. This fall generates significant noise and impact force, causing damage to every structure of the equipment with each impact. It can loosen screw fasteners and easily trigger false alarms in electrical components, posing a safety hazard. Summary of the Invention

[0018] A retaining ring is installed above the washers on the lower and upper sections of the bushing, and the retaining ring is provided with a waist-shaped hole that matches the shape of the outer peripheral surface of the upper and lower sections of the bushing.

[0019] A bolt is inserted into the upper end face of the bushing and passes through the lower end of the bushing to be threadedly connected and fixed to the clamp. The washer is pressed onto the shoulder of the bushing by tightening the bolt.

[0020] The middle section of the bushing is located inside the track and is used for guidance; the washer presses against the upper surface of the upper connecting seat and is used to suspend the clamp on the connecting seat.

[0021] In one embodiment, the washer comprises:

[0022] The upper pad is used to increase the strength of the gasket;

[0023] The lower pad is used to reduce friction with the upper surface of the track;

[0024] The upper pad and the lower pad are fixedly connected, one on top of the other.

[0025] In one embodiment, the lower surface of the connecting seat is provided with a through hole that allows the clamp to pass through.

[0043] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0044] Example 1

[0045] In bridge construction, piers are built first, and after the piers are completed, cap beams are erected on them before the outer shell is placed on top. This embodiment provides a climbing device for cap beam construction. Utilizing the already constructed piers, the climbing device moves up and down along the piers to transport mechanical clamps, steel structural beams, and other components used in cap beam construction to the upper part of the piers. Specifically, the climbing device includes:

[0046] A clamp is provided on a pier column with two clamps arranged vertically. Each clamp includes two sub-lobes, each sub-lobe having a first end and a second end. The first ends of the two sub-lobes are connected by a hinge shaft. When the end faces of the second ends of the two sub-lobes contact, the clamp closes and locks the pier column. The automatic clamp structure in the patent with publication number CN218564091U is one of the embodiments of the clamp described in this example.

[0047] Connecting seat, each clamp is equipped with one connecting seat, refer to Figure 1 The clamp (including the first sub-petal 1 and the second sub-petal 2) is suspended in the inner cavity of the connecting seat (including the left connecting seat 2101 and the right connecting seat 2102) by the lifting seat 22. The upper end of the lifting seat 22 is connected to the connecting seat, and the lower end of the lifting seat 22 is connected to the clamp. The upper surface of the connecting seat is provided with a track 24, and the lifting seat 22, which connects the second end of the sub-petal to the connecting seat, can move within the track 24.

[0048] A power structure (not shown in the figure) is installed on the connecting seat and is used to change the distance between the two clamps on a bridge pier. This embodiment of the power structure is one of the implementations of the power structure described in the patent document with publication number CN115652809A, which describes a plurality of rigid chains being arranged between the upper and lower connecting seats.

[0049] To install the clamp within the connecting seat, the height of the connecting seat's inner cavity must be slightly greater than the height of the clamp. In the climbing device provided in this embodiment, because the clamp is suspended from the upper surface of the connecting seat using the hoisting seat 22, the position between the clamp and the connecting seat will not change when the clamp is released during the climbing process, preventing the clamp from falling to the lower surface of the connecting seat. This reduces the impact of the clamp on the connecting seat and the entire mechanism, resulting in higher reliability.

[0050] In this embodiment, an arc-shaped cross-section hole penetrating the upper plane of the connecting seat is provided as a track 24; when the hoisting seat 22 passes through the track 24, the track 24 can restrict the movement trajectory of the hoisting seat 22.

[0051] The upper surface of the connecting seat is partially provided with a boss, the surface roughness of the upper surface of the boss is small, and a track 24 is provided at the boss.

[0052] In this embodiment, a hole identical to the inner cavity is directly removed from the upper surface of the connecting seat to form a track 24, which is easy to process. The lifting seat 22 can be directly suspended from the upper surface of the connecting seat through the hole-shaped track 24. The two sides of the track 24 need to bear the weight transmitted from the clamp through the lifting seat 24. Therefore, in this embodiment, the track 24 is set at the boss to improve the strength of the track 24. When the clamp is opened, the lifting seat 22, which connects the second end of the sub-lobe to the connecting seat, slides on the upper surface of the boss. In this embodiment, the surface roughness of the upper surface of the boss is set to be small, which helps to reduce the resistance to the movement of the lifting seat 22 and avoid jamming that would hinder the clamp opening process.

[0053] Furthermore, in this embodiment, the position of the clamp mounting bracket 22 includes: the hinge shaft and the second ends of the two sub-lobes;

[0054] Reference Figure 2 and Figure 3 The boss has a through hole 2401 at its center, and rails 24 are symmetrically arranged on both sides of the through hole 2401;

[0055] The two bosses are arranged symmetrically on the upper surface of the upper connecting seat.

[0056] In this embodiment, the two protrusions are mirror-symmetrically arranged on the upper plane of the upper connecting seat. The left connecting seat 2101 and the right connecting seat 2102 have the same structure. When installing the climbing device, there is no need to distinguish them, which simplifies the installation difficulty and improves the installation efficiency at the construction site.

[0057] In this embodiment, refer to Figure 4 and Figure 9 An anti-slip cover 26 is installed above the boss to prevent foreign objects from entering the track 24 during construction, and to further ensure the safety of opening and closing the clamp.

[0058] In this embodiment, refer to Figure 5 and Figure 6 The lifting base 22 includes:

[0059] The bushing 2207 has a through hole in the shaft center. The bushing 2207 includes an upper section, a middle section and a lower section. The outer diameter of the middle section of the bushing 2207 is the largest. The outer diameters of the upper and lower sections of the bushing 2207 are smaller than the outer diameter of the middle section. The outer peripheral surfaces of the upper and lower sections of the bushing 2207 are configured to fit the shape of the waist-shaped hole.

[0060] Washers (including upper washer 2205 and lower washer 2206) are installed on the upper section of bushing 2207 and form a shaft hole fit relationship with the upper section;

[0061] The retaining ring includes an upper retaining ring 2204 and a lower retaining ring 2208. The upper retaining ring 2204 is installed on the upper section of the bushing 2207, and the lower retaining ring 2208 is installed above the washer on the lower section of the bushing 2207. Both the upper retaining ring 2204 and the lower retaining ring 2208 are provided with waist-shaped holes that fit the shape of the outer peripheral surface of the upper and lower sections of the bushing 2207.

[0062] Bolt 2201 is inserted into the upper end face of bushing 2207 and passes through the lower end of bushing 2207 to be threadedly connected and fixed to the clamp. By tightening bolt 2201, the upper pad 2205 is pressed onto the shoulder between the middle and upper sections of the bushing, and the lower pad 2206 is pressed onto the shoulder between the middle and lower sections of the bushing.

[0063] The middle section of bushing 2207 is located inside track 24 and is used for guidance; the washer presses against the upper surface of the upper connecting seat and is used to suspend the clamp on the connecting seat.

[0064] In this embodiment, by setting the bushing 2207 and making the bushing into a stepped shaft shape, and ensuring that it is non-rotatable from the retaining ring, the bolt 2201 can be prevented from being loosened by the rotation driven by the washer during the opening and closing of the clamp.

[0065] To ensure that bolt 2201 can be tightened, flat washer 2203 and spring washer 2202 are also provided.

[0066] In this embodiment, the washer comprises:

[0067] The upper gasket 2205 is used to increase the strength of the gasket and can be made of a high-strength material such as carbon steel.

[0068] The lower pad 2206 is used to reduce friction with the upper surface of the track and can be made of a material with a low coefficient of friction.

[0069] The upper pad 2205 and the lower pad 2206 are fixedly connected one above the other, or they can be connected by a detachable connection method such as threads. When the lower pad 2206 is severely worn, only the lower pad 2206 needs to be replaced, which reduces costs.

[0070] Reference Figure 4 and Figure 7 The lower retaining ring 2208 and nut 2209 of the lifting seat 22 connected to the second end of the sub-lobe are coaxially fixed to one side of the lower surface of the second end of the sub-lobe, and the lower end of the bolt 2201 is threadedly connected and fixed to the nut 2209.

[0071] Reference Figure 4 and Figure 8The lower retaining ring 2208 of the lifting seat 22 connected to the hinge shaft of the sub-lobe is threadedly connected and fixed to the threaded hole provided in the hinge shaft of the sub-lobe.

[0072] In existing technology, the connecting seat needs to be horizontally fitted onto the outside of the clamp, which is difficult to operate. Especially for the connecting seat that matches the upper clamp, a large crane is required for hoisting during the fitting process. It is difficult to ensure accurate hoisting position during hoisting, causing on-site installation difficulties. Furthermore, during hoisting, the connecting seat is prone to damaging the clamp's motor or cables. In this embodiment, referring to... Figure 10 The lower surface 2104 of the connecting seat is provided with a through hole 2105 that allows the clamp to pass through. In this embodiment, the through hole 2105 of the lower surface 2104 of the upper connecting seat allows the clamp to pass through, and the upper connecting seat can be lowered onto the clamp during installation, making installation simpler and faster.

[0073] In this embodiment, refer to Figure 1 A detachable truss structure 23 is installed on the upper surface 2103 of the connecting seat that accommodates the upper clamp. The crossbeam used for cap beam construction is placed on the truss structure 23, and the mechanical clamp used for cap beam construction is placed on the upper surface 2103 of the connecting seat and located between the two truss structures 23. By setting the truss structure 23 supporting the crossbeam and mechanical clamp used for cap beam construction to be detachably connected to the connecting seat, material utilization can be improved and material and manufacturing costs can be reduced.

[0074] During the installation and dismantling of the climbing device, the connecting seat needs to be hoisted in various working conditions. Therefore, in this embodiment, the connecting seat is provided with multiple lifting lugs. After the connecting seat is hoisted by the lifting lugs, the upper plane of the connecting seat is horizontal. By providing the lifting lugs, it is easy to determine the hoisting position and facilitate the hoisting construction.

[0075] As described above, the connector is divided into two parts: a left-side connector 2101 on the left and a right-side connector 2102 on the right. Continuing to refer to... Figure 1 The left connecting seat 2101 on the left side and the right connecting seat 2102 on the right side of the connecting seat have partially arranged on the outer side of the connecting seat. This provides a larger operating space for workers, makes bolt tightening more convenient and faster, and improves installation efficiency.

[0076] This embodiment also provides a method for assembling and disassembling the climbing device described above, wherein the connecting seat falls onto or leaves the clamp from above the clamp.

[0077] In this embodiment, the climbing device can be installed by fitting the connecting seat over the outside of the clamp before installing the lifting seat. The lower surface 2104 of the connecting seat has a through hole 2105 allowing the clamp to pass through horizontally. Therefore, the connecting seat can fall onto or leave the clamp from above. The left side connecting seat 2101 on the left and the right side connecting seat 2102 on the right can fall onto the clamp from above and then be connected. Alternatively, the left side connecting seat 2101 on the left and the right side connecting seat 2102 on the right can be connected before descending onto the clamp. This method is particularly simple and efficient for disassembling the upper connecting seat.

[0078] The piers supporting the bridge deck are often two or more. The method of hoisting them from above also avoids interference when installing the connecting seats on the adjacent sides of two adjacent piers.
