Abstract
Description
Technical Field
[0001] This application relates to the technical field of bridge construction, and in particular to a bridge construction support device. Background Technology
[0002] A bridge is a structure erected over rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure, supports, and auxiliary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the points where the bridge span structure supports the piers or abutments.
[0003] Bridge construction and maintenance operations require the use of bridge construction support equipment to improve safety; however, due to the varying sizes of the main structures such as bridge decks and beams, the weight borne by the bridge construction support equipment also varies. Current bridge construction support equipment is insufficient to meet the needs of use and there is still room for improvement. Utility Model Content
[0004] In order to improve the load-bearing capacity of bridge construction support equipment and make it applicable to situations where the main structures such as bridge decks and beams are of different sizes and weights, this application provides a bridge construction support equipment.
[0005] The bridge construction support equipment provided in this application adopts the following technical solution:
[0006] A bridge construction support device includes a support base for supporting the bridge. The support base is supported by a support mechanism, which includes a support column, a diagonal brace, and a fixed base fixed to the ground. The support column is connected between the support base and the fixed base. One end of the diagonal brace is rotatably connected to the side wall of the support column, and the bottom of the diagonal brace is positioned on the fixed base by a positioning structure. The positioning structure includes an extension movably disposed at the end of the diagonal brace, which extends and is fixed to the fixed base.
[0007] By adopting the above technical solution, the support column is supported by a fixed base and rests on the bottom of the support seat. The inclined extension of the diagonal brace at the end is used, and it is further fixed to the fixed base by a movable extension part. This improves the load-bearing capacity of the fixed base on the support seat, making the bridge construction support equipment applicable to situations where the main structures such as bridge decks and beams are of different sizes and weights, thus improving its practicality.
[0008] Preferably, an extension plate that can be extended and fixed outside the fixed base is installed on the side wall of the fixed base. The positioning structure also includes a positioning part fixed to the bottom of the extension part and a plug plate movably connected to the extension plate. The extension plate has an installation groove for accommodating the positioning part. The plug plate is located on one side of the positioning part and passes through the upper part of the extension plate. A fixing plate that is plugged into the positioning part is fixed on the plug plate. An abutment plate that abuts against the extension plate extends and is fixed on the plug plate. A positioning bolt that is positioned against the abutment plate is threadedly connected to the extension plate.
[0009] By adopting the above technical solution, the fixing plate on the plug plate is plugged into the positioning part, which improves the stability of the positioning part in the mounting groove, thereby making the diagonal brace stably supported on the extension plate; the plug plate passes through the upper part of the extension plate to facilitate the control of the movement of the plug plate, and the abutment plate abuts against the lower part of the extension plate to facilitate the positioning bolts to lock the plug plate and the fixing plate into the positioning part.
[0010] Preferably, the support mechanism further includes a lifting column and a push plate. A cylinder is fixed inside the support column, the lifting column is fixed to the output shaft of the cylinder, the push plate is fixed to the bottom of the lifting column and passes through the outside of the support column, and the end of the push plate can abut against the side wall of the diagonal brace.
[0011] By adopting the above technical solution, the cylinder drives the lifting column and the push plate to rise. When the side wall of the push plate abuts against the bottom of the diagonal brace, it can cause the diagonal brace to rotate in the direction of the fixed base. No manual pushing is required, which increases the support area below and provides greater load-bearing capacity for the bridge.
[0012] Preferably, the extension plate is connected to the fixed base via a connecting structure.
[0013] Preferably, the connection structure includes a connecting rod and a connecting sleeve. Both ends of the extension plate are provided with insertion holes. The connecting rod is fixed in the insertion holes. The upper part of the connecting sleeve is provided with threads. The connecting sleeve is inserted into the corresponding insertion holes of the fixed base and the extension plate. The connecting sleeve is sleeved outside the connecting rod and passes through the upper part of the fixed base. The upper part of the connecting sleeve is threaded with a locking nut that abuts against the fixed base.
[0014] By adopting the above technical solution, both ends of the extension plate are provided with insertion holes for connecting sleeves. When the extension plate is housed in the fixed base or passes through the fixed base, it can be fitted onto the connecting rod at the corresponding position by the connecting sleeve and fixed by the locking nut, thereby achieving the purpose of positioning the extension plate.
[0015] Preferably, the fixed base has a clearance groove for the diagonal brace to rotate.
[0016] By adopting the above technical solution, the setting of the clearance groove avoids the fixed base from hindering the rotation of the bottom of the diagonal brace.
[0017] Preferably, a guide rod is fixed on the side wall of the extension and passes through the side wall of the diagonal brace. A guide groove is provided on the side wall of the diagonal brace for the guide rod to slide. When the extension is housed in the diagonal brace, the guide rod is positioned by a limiting member.
[0018] By adopting the above technical solution, the guide rod and guide groove are extended and positioned on the diagonal brace.
[0019] Preferably, the limiting component includes a limiting plate and a sliding block made of rubber. The limiting plate abuts against the guide rod, the sliding block is T-shaped and fixed to the limiting plate, and the sliding block is slidably connected to the corresponding position on the diagonal brace.
[0020] By adopting the above technical solution, the rubber sliding block will not move easily. The limiting plate abuts against the positioning guide rod, which makes it easy to position the extension in the position accommodated in the diagonal brace.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] The support column is supported by a fixed base and rests on the bottom of the support seat. It utilizes the inclined extension of the diagonal brace at the end, and is further fixed to the fixed base by a movable extension part, thereby increasing the load-bearing capacity of the fixed base on the support seat. This makes the bridge construction support equipment applicable to situations where the main structures such as bridge decks and beams are of different sizes and weights, thus improving its practicality.
[0023] Both ends of the extension plate have insertion holes for connecting sleeves. When the extension plate is housed inside the fixed base or passes through the fixed base, it can be fitted with the connecting rod at the corresponding position through the connecting sleeve and fixed by the locking nut to achieve the purpose of positioning the extension plate.
[0024] The fixing plate on the plug plate is inserted into the positioning part, which improves the stability of the positioning part in the mounting groove, thereby making the diagonal brace stably supported on the extension plate; the plug plate passes through the upper part of the extension plate to facilitate the control of the movement of the plug plate, and the abutment plate abuts against the lower part of the extension plate to facilitate the positioning bolts to lock the plug plate and the fixing plate into the positioning part.
