Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction equipment, and more specifically, it relates to a double-clamp method cap beam construction platform. In addition, this invention also relates to a double-clamp method cap beam construction method. Background Technology

[0002] In bridge construction, the bridge clamp method is a commonly used construction method. Bridge clamps provide support for the subsequent installation of formwork. In practice, the bridge clamps need to be preliminarily assembled on the ground first. Then, a crane or hoist is used to lift the bridge clamps and place them on the outside of the bridge pier from above. Once the clamps are in the appropriate position, workers use various lifting tools to raise and secure the bridge clamps to the pier.

[0003] However, it must be said that in actual construction, large lifting equipment is often charged based on working hours. During the tightening process of bridge clamps, the lifting equipment needs to continuously suspend the bridge clamps in mid-air, which increases the usage time of the lifting equipment and thus increases the construction cost. Summary of the Invention

[0004] The purpose of this invention is to provide a double-clamp method cap beam construction platform to facilitate the installation of clamp components and thereby reduce the construction cost of cap beams.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A double-clamp method cap beam construction platform is provided, comprising a suspended platform body, a lifting mechanism, and a limiting clamp assembly. The suspended platform body is box-shaped, with an insertion hole in the middle. A bridge pier is inserted into the insertion hole, so that the suspended platform body surrounds the bridge pier. The lifting mechanism is located on the ground and connected to the suspended platform body, and is used to drive the suspended platform body to slide up and down. The limiting clamp assembly is detachably mounted on the suspended platform body and slidably mounted on the suspended platform body. The limiting clamp assembly can abut against the bridge pier due to sliding, at which point it can be locked and fixed to the bridge pier, and the limiting clamp assembly can also release its contact with the bridge pier due to sliding.

When the guardrail is closed, the fixing sub-blocks of two guard plates on the same side are combined to form a fixing block, and U-shaped fasteners are inserted into the two fixing holes of the same fixing block, so that the two guard plates on the same side are fixed.

[0010] In one possible implementation, the limiting clamp assembly includes four sub-clamps, which are fan-shaped; the top surface of the mounting plate is provided with a sliding groove that extends along the diameter of the slot; a clamp support is slidably disposed within the sliding groove, the clamp support including a vertically arranged vertical rod and a horizontally arranged horizontal rod, the horizontal rod being rotatably connected to the top end of the vertical rod, the bottom end of the vertical rod being inserted into the sliding groove, the sub-clamps being provided with support holes, and the horizontal rod being screwed into the support holes.

[0046] Example 1

[0047] The double-clamp method cap beam construction platform provided by the present invention will now be described.

[0048] Please refer to the following: Figure 1 and Figure 2 The double-clamp method cap beam construction platform includes a suspended platform body 1, a lifting mechanism 2, and a limiting clamp assembly 3. The suspended platform body 1 is box-shaped, with an insertion hole 101 in the middle. The bridge pier 4 is inserted into the insertion hole 101, so that the suspended platform body 1 is arranged around the bridge pier 4. The lifting mechanism 2 is located on the ground and connected to the suspended platform body 1. The lifting mechanism 2 is used to drive the suspended platform body 1 to slide up and down. The limiting clamp assembly 3 is detachably installed on the suspended platform body 1 and slides on the suspended platform body 1. The limiting clamp assembly 3 can abut against the bridge pier 4 due to sliding. At this time, the limiting clamp assembly 3 can be locked and fixed on the bridge pier 4, and the limiting clamp assembly 3 can also be released from abutment with the bridge pier 4 due to sliding.

[0049] The beneficial effects of the double-clamp method cap beam construction platform provided in this embodiment are as follows: Compared with the prior art, the double-clamp method cap beam construction platform provided in this embodiment sets a limiting clamp component 3 on the suspended basket body 1, and fixes the limiting clamp component 3 on the bridge pier column 4. The setting of the limiting clamp component 3 can support the bridge clamp during construction. Compared with continuously using lifting equipment to suspend the bridge clamp in mid-air, it can greatly reduce the use time of the lifting equipment, thereby reducing the use cost of the lifting equipment.

[0050] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the suspended platform body 1 includes a work platform 102, a guardrail 103, and multiple balancing components 104. The work platform 102 is assembled from multiple mounting plates 105. The guardrail 103 is detachably mounted on the top of the work platform 102 and is arranged circumferentially along the work platform 102. Multiple balancing components 104 are mounted on the work platform 102, with parts of each balancing component 104 located within insertion holes 101, and one end of each balancing component 104 abutting against the bridge pier 4. The work platform 102, composed of multiple mounting plates 105, facilitates disassembly, allowing the mounting platform to be installed around the bridge pier 4 from the ground, unlike bridge clamps which require insertion from above the bridge pier. The balancing components 104 help maintain the suspended platform body 1's horizontal position during ascent.

[0051] As such, there are four mounting plates 105, and the cross-section of each mounting plate 105 is square. A slot 106 is provided at one corner of each mounting plate 105. The slot 106 has a fan-shaped cross-section. When the four mounting plates 105 are assembled into a workbench 102, the four slots 106 form an insertion hole 101. A connecting plate 107 is provided on one side wall of each mounting plate 105, and a first connecting hole 108 is provided on the connecting plate 107. A connecting groove 109 is provided on the other side wall of each mounting plate 105, and a second connecting hole 110 passes through the connecting groove 109. In two adjacent mounting plates 105, the connecting plate 107 of one mounting plate 105 is inserted into the connecting groove 109 of the other mounting plate 105, and a first bolt is screwed into the corresponding first connecting hole 108 and second connecting hole 110 to fix the two adjacent mounting plates 105. The connecting plate 107 and the connecting groove 109 facilitate the connection and fixation between adjacent mounting plates 105.

[0052] In this embodiment, the arc-shaped sidewall of the slot 106 is provided with a telescopic hole 111, and the inner wall of the telescopic hole 111 is provided with a first thread. For example... Figure 7As shown, the balancing component 104 includes a roller assembly 113 and a telescopic rod 112. The telescopic rod 112 has a second thread on its side wall, which is compatible with the first thread. A portion of the telescopic rod 112 is screwed into the telescopic hole 111. The roller assembly 113 is located on the portion of the telescopic rod 112 outside the telescopic hole 111. The roller assembly 113 can rotate relative to the telescopic rod 112, allowing the rollers to move away from or closer to the bridge pier 4 due to the rotation of the telescopic rod 112. Limiting holes 114 are provided on both sides of the telescopic hole 111, and limiting rods 115 are provided on the roller assembly 113, which are inserted into the limiting holes 114. The expansion and contraction of the balancing component 104 within the telescopic hole 111 allows the suspended platform body 1 to be adapted to bridge piers of different diameters.

[0053] like Figure 4 The workbench 102 has mounting blocks 116 at each of its four corners, and each mounting block 116 has a pivot hole 117. The guardrail 103 includes eight guard plates 118, and each guard plate 118 has a pivot rod 119 on its side wall. Each guard plate 118 corresponds to a mounting block 116, and the pivot rod 119 of each guard plate 118 is inserted into the corresponding pivot hole 117, allowing the guard plate 118 to rotate around the pivot rod 119 to open or close the guardrail 103 on either side. Near the top of each guard plate 118 is a fixing sub-block 120, which has a fixing hole 121. When the guardrail 103 is closed, the fixing sub-blocks 120 of two guard plates 118 on the same side are combined to form a fixing block 122. A U-shaped fastener is inserted into the two fixing holes 121 of the same fixing block 122, thus fixing the two guard plates 118 on the same side. The installation of multiple guardrails 118 allows each side of the guardrail 103 to be opened, facilitating the entry and exit of construction personnel.

[0054] Combination Figure 1 and Figure 2 The limiting clamp assembly 3 includes four sub-clamps 123, which are fan-shaped; a sliding groove 124 is provided on the top surface of the mounting plate 105, which extends along the diameter of the slot 106; a clamp support member 125 is slidably disposed within the sliding groove 124. Figure 6 As shown, the clamp support 125 includes a vertically arranged vertical rod 126 and a horizontally arranged horizontal rod 127. The horizontal rod 127 is rotatably connected to the top of the vertical rod 126, and the bottom end of the vertical rod 126 is inserted into the sliding groove 124. The sub-clamp 123 has a support hole, and the horizontal rod 127 is screwed into the support hole. When the suspended platform body 1 rises, the sliding clamp support 125 causes the sub-clamp 123 to disengage from the bridge pier, facilitating the rise of the suspended platform body 1. The connection between the clamp support 125 and the sub-clamp 123 facilitates the self-fixation of the sub-clamp 123 during installation, and also provides support for the suspended platform body 1 after the installation of the *Hylocereus undatus*.

[0055] like Figure 1 and Figure 8 As shown, the lifting mechanism 2 includes a base 201, a support rod 202, a pulley block 203, a lifting cable 204, and a drive motor 205. The base 201 is located on the ground, and the support rod 202 is fixedly mounted on the base 201, extending vertically upwards. The pulley block 203 is located at the top of the support rod 202. The drive motor 205 is located on the base 201, and a winding shaft 206 is provided at the power output end of the drive motor 205. The lifting cable 204 passes through the pulley block 203, with one end of the lifting cable 204 fixed to the winding shaft 206 and the other end fixed to the workbench 102. The drive motor 205 drives the winding shaft 206 to rotate, winding the lifting cable 204 onto the winding shaft 206, causing the suspended basket body 1 to rise; the drive motor also drives the winding shaft 206 to rotate, unwinding the lifting cable 204 onto the winding shaft 206, causing the suspended basket body 1 to descend.

[0056] One end of the lifting cable 204 is provided with a lifting plate, and the lifting plate is provided with an upwardly extending lifting column. The bottom of the mounting plate 105 is provided with a lifting cylinder, and the lifting column is inserted into the lifting cylinder.

[0057] As a preferred technical solution, the base 201 has a take-up groove 207 at its top, and the cross-section of the take-up groove 207 is T-shaped; the bottom of the drive motor 205 has a slider that is adapted to the take-up groove 207 and is inserted into the take-up groove 207; the base has a displacement plate 208 with displacement holes; the end of the take-up shaft 206 has a displacement rod 209 that is screwed into the displacement hole. During take-up and unwinding, the take-up shaft 206 moves left and right to prevent the lifting cable 204 from getting tangled on the take-up shaft 206.

[0058] Finally, the base 201 is provided with multiple positioning holes 210, each located at one of the four corners of the base 201; a fixing rod 211 is inserted into each positioning hole 210, the fixing rod 211 includes a rod with a tapered bottom and a retaining rod at the top of the rod, a portion of the rod extending below the base and inserted into the soil, the retaining rod having a diameter larger than the diameter of the positioning hole 210, and the retaining rod abutting against the base. The positioning holes 210 and the fixing rod 211 facilitate the fixing of the lifting mechanism 2.
