Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a liftable cap beam construction platform. Background Technology

[0002] The cap beam is an important component in bridge engineering, usually located on top of the piers, used to support and transfer the load of the superstructure. The cap beam directly supports the main beam or slab beam of the bridge and transfers the load to the piers. Standardized installation of cap beams involves prefabricating them in the factory and then transporting them to the site for installation. Current technology requires setting up a construction platform around the piers during installation. A lifting structure is installed at the bottom of the construction platform. The cap beam is supported on the construction platform by load-bearing beams and bottom formwork. The lifting structure is used to lift and install the cap beam. The lifting structure is rail-type, but the lifting rail is often directly set on the outer surface of the pier, requiring many connecting devices (such as anchor bolts) to connect the rail and the pier. Due to the large mass of the cap beam, this method of lifting the cap beam will cause significant damage to the outer wall of the pier, affecting the quality of the pier. Utility Model Content

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, a liftable cap beam construction platform includes a track assembly 3, several stabilizing components 7, a load-bearing component 2, and a lifting structure disposed on one side of the load-bearing component 2. The cap beam 101 is supported on the upper end of the load-bearing component 2 by a load-bearing beam 102 and a bottom formwork 103. The load-bearing beam 102 is supported on the load-bearing component, the bottom formwork 103 is supported on the load-bearing beam 102, and the cap beam 101 is supported on the bottom formwork 103. The track assembly 3 is disposed on the outer wall of the pier 1. The track assembly 3 includes a track 32 and several support seats 31. The support seats 31 are fixedly disposed on the cylindrical surface on the outer side of the pier 1 and are fixed by anchoring. The several support seats 31 are arranged on the same axis. The track 32 is disposed inside the support seats 31. In the prior art, the track 32 is often directly fixed to the pier 1, which will affect the surface quality of the pier 1. After setting the support base 31, the number of connecting devices between the track 32 and the pier 1 is reduced while ensuring connection stability. This reduces the damage to the outer surface of the pier 1 caused by the connecting devices and avoids affecting the quality of the pier 1. The support base 31 is equipped with a connecting rod 311, which passes through the track 32 to fix the track 32. Multiple tracks 32 are set outside the pier 1. When installing the track assembly 3, the position of each support base 31 is calculated according to the height of the pier 1. The support bases 31 are installed one by one on the outer wall of the pier 1. After installation, the track 32 is placed inside the support base 31. The connecting rod 311 is inserted at one end of the support base 31, so that the connecting rod 311 passes through the track 32 and extends from the other end of the support base 31. After the track 32 is connected to each support base 31, the track 32 is fixed.

[0029] like Figure 1-9As shown, the load-bearing component 2 is located outside the track component 3. The load-bearing component 2 includes an upper load-bearing plate 21 and a lower load-bearing plate 22, which are connected by a connecting rod 23. The load-bearing component 2 is the main structure of the construction platform, and workers can stand between the upper load-bearing plate 21 and the lower load-bearing plate 22 to work. The lifting structure is connected to the track component 3. The lifting structure includes several connecting parts 4, support parts 6, and a telescopic drive part 5. The connecting parts 4 include a connecting frame 41, a locking block I 42, and a limiting rod I 43. The connecting parts 4 are fixedly connected to the upper and lower sides of the load-bearing component 2. One set of connecting parts 4 is connected to the upper load-bearing plate 21, and the other set of connecting parts 4 is connected to the upper load-bearing plate 21. The lower support plate 22 is connected, and a shaft is provided in the middle of the locking block I 42. The two sides of the shaft are connected to the connecting frame 41, so that the locking block I 42 is rotatably set inside the connecting frame 41. The limiting rod I 43 is detachably inserted into the connecting frame 41. The limiting rod I 43 and one end of the locking block I 42 abut against each other. When the bottom end of the locking block I 42 rotates outward toward the connecting frame 41, the top end of the locking block I 42 gradually approaches the inner wall of the connecting frame 41. When the top end of the locking block I 42 is in close contact with the inner wall of the connecting frame 41, the bottom end of the locking block I 42 protrudes outward from the connecting frame 41. At this time, the limiting rod I 43 is inserted into the connecting frame 41, and the limiting rod I 43 locks the locking block I 42, restricting the movement of the locking block I 42.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, the support member 6 also includes a locking block II 62, a support frame 61, and a limiting rod II 63. The support frame 61 has a hole, and the limiting rod II 63 is detachably inserted into the support frame 61 through the hole. The locking block II 62 is rotatably connected inside the support frame 61, with one end of the limiting rod II 63 abutting against the locking block II 62. A shaft is provided in the middle of the locking block II 62, and both sides of the shaft are connected inside the support frame 61, allowing the locking block II 62 to be rotatably mounted inside the support frame 61. The limiting rod II 63... 3. A detachable insert is made into the support frame 61. One end of the limiting rod II 63 and the locking block II 62 abuts against each other. When the bottom end of the locking block II 62 rotates outward toward the support frame 61, the top end of the locking block II 62 gradually approaches the inner wall of the support frame 61. When the top end of the locking block II 62 is in close contact with the inner wall of the support frame 61, the bottom end of the locking block II 62 extends outward from the support frame 61. At this time, the limiting rod II 63 is inserted into the support frame 61, and the limiting rod II 63 locks the locking block II 62, restricting the movement of the locking block II 62.

[0031] like Figure 1-9As shown, the driving component 5 is a cylinder, but it can also be other telescopic structures. One end of the driving component 5 extends into the connecting frame 41 at the position of the upper load-bearing plate 21 and is hinged to the connecting frame 41. One end of the telescopic rod of the driving component 5 extends into the support frame 61 and is hinged to the support frame 61. One end of the track 32 is slotted, and several protruding plates 321 are provided in the slot. In the initial position, the connecting frame 41 and the protruding plates 321 are aligned, the locking block I 42 rotates and abuts against the protruding plate 321, and the limiting rod I 43 is inserted into the connecting frame 41 to restrict the movement of the locking block I 42. At this time, the load-bearing component 2 is fixed on the track 32. Rotating the locking block II 62 causes the locking block II 62 to abut against the protruding plate 321, and the limiting rod II 63 is inserted into the support frame 61 to restrict the movement of the locking block II 62. Pulling the limiting rod I 43 out of the connecting frame 41, the locking block I 42 resets and separates from the protruding plate 321. At this time, the cap beam 101 is level. The platform is supported on the track 32 by locking block II 62, driving the drive component 5 to move. The shaft of the drive component 5 extends and lifts the load-bearing component 2 towards the upper end of the pier 1. When the connecting frame 41 is aligned with the upper convex plate 321, the locking block I 42 is rotated so that the locking block I 42 and the convex plate 321 abut. Then, the limiting rod I 43 is inserted into the connecting frame 41, and the load-bearing component 2 is supported on the convex plate 321 again. The limiting rod II 63 is removed from the support frame 61, so that the locking block II 62 is reset. The locking block II 62 leaves the convex plate 321, driving the drive component 5 to move. The shaft of the drive component 5 is reset, bringing the support component 6 back to the initial position, realizing the rise of the cap beam 101 construction platform along the track 32. When the cap beam 101 construction platform rises to the upper end of the pier 1, the worker can stand on the upper load-bearing plate 21 to connect the cap beam 101 to the pier 1. The operation is reversed when descending.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 9 As shown, the support base 31 is provided with several support rods 312 inside. The support rods 312 are detachably inserted into the two sides of the support base 31. The upper end of the connecting frame 41 is provided with curved grooves 411 on both sides. The curved grooves 411 are connected to the support rods 312. When the limiting rod I 43 is removed, the connecting frame 41 can be temporarily supported at the position of the support rods 312 through the curved grooves 411. Then the locking block II 62 and the protruding plate 321 are connected to prevent the construction platform of the cap beam 101 from falling.

[0033] like Figure 5 , Figure 6As shown, a pad 71 is provided at the lower end of the connector 4, and the stabilizing component 7 is set on the pad 71. The stabilizing component 7 includes a stabilizing frame 72 and a roller 73. The stabilizing frame 72 and the pad 71 are detachably connected by bolts. The roller 73 is rotatably set at one end of the stabilizing frame 72, and the roller 73 is in close contact with the surface of the pier 1. Since the stabilizing component 7 is directly connected to the surface of the pier 1, the installation status of the connector 41 can be judged by the position of the stabilizing component 7 during installation. If one set of stabilizing components 7 cannot be in close contact with the surface of the pier 1 when installed in the installation position on the pad 71, it indicates that the installation of the load-bearing component 2 has been offset. The installation position of the load-bearing component 2 can be adjusted in time to avoid failure in the subsequent lifting process. The roller 73 is in close contact with the surface of the pier 1. During the lifting and lowering process of the cap beam 101 construction platform, the stabilizing component 7 increases the friction, making the lifting process more stable, while not affecting the surface quality of the pier 1.

[0034] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
