Description

Technical Field

[0001] This utility model relates to the technical field of bridge construction, and in particular to a telescopic support for bridge construction. Background Technology

[0002] Bridges are structures built to facilitate traffic flow and make travel more convenient. During bridge construction, scaffolding is often used to facilitate aerial work. Most existing scaffolding systems are adjustable by extending vertically, which limits their operational range. When work needs to be moved, the scaffolding needs to be reinstalled, which is inconvenient.

[0003] Chinese Patent Publication No. CN218406379U, published on January 31, 2023, discloses a bridge construction support frame, including a movable base, a first hydraulic telescopic rod for lifting and lowering the working chamber, and a second hydraulic telescopic rod for lateral displacement of the working chamber. The frame is characterized by: two sets of first hydraulic telescopic rods symmetrically arranged at the upper end of the movable base, with their telescopic ends fixed to a support plate; a working chamber for lifting and lowering personnel located at the upper end of the support plate; two sets of locking blocks offset at the bottom of the working chamber; two sets of limiting grooves symmetrically arranged inside the support plate, penetrating and engaging with the locking blocks; a connecting block offset at the bottom of the support plate, corresponding to the locking blocks and fixed to the second hydraulic telescopic rod; and a motor placement cavity for protecting and placing the winding motor inside the working chamber. The drawback of this invention is that the support frame can only perform lifting and lowering movements, limiting the construction range during construction. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies where the support needs to be reinstalled when the construction site needs to be changed, and provides a telescopic support for bridge construction that can expand the construction range.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A telescopic support for bridge construction, comprising: Base; The telescopic sleeve is provided in a plurality of units and connected in sequence, and the base is connected to the telescopic sleeve at the bottom end; A lifting plate, wherein the lifting plate is installed on the telescopic sleeve at the top end; A rotating assembly, which is mounted on a lifting plate; The construction frame is mounted on the rotating assembly and is slidably connected to the rotating assembly.

[0006] The entire device is installed on a base, with several telescopic sleeves arranged in sequence. These sleeves can extend and retract to raise the top-mounted lifting plate to a designated height. Before the telescopic sleeves raise the lifting plate, construction workers enter the construction frame. After reaching the designated height, the construction frame is rotated to align with the construction position by rotating the component. The construction frame is then moved to the construction site by sliding on the rotating component. This sliding mechanism between the rotating component and the construction frame allows for better alignment with the construction site, thereby expanding the construction area and reducing the number of times the support structure needs to be moved, thus achieving the goal of expanding the construction scope.

[0007] Preferably, the base is equipped with several evenly distributed hydraulic cylinders and several evenly distributed extension rods. One end of each extension rod is connected to the base, and the other end is fitted with a contact block. The base has a storage groove that matches the contact block. The evenly distributed hydraulic cylinders on the base are connected to a telescopic sleeve, which can lift the telescopic sleeve away from the base. The base is then fixed to the ground for reinforcement. When fixing the base, the extension rods at the four corners of the base need to be rotated, turning the end of the extension rod with the contact block out of the storage groove and away from the base. The base and the contact block are then disconnected from the ground. The extension rods increase the contact area between the base and the ground, and the contact blocks on the extension rods improve the stability of the base. Simultaneously, the extension rods can be rotated to fit snugly against the base for storage. This design enhances stability.

[0008] Preferably, the telescopic sleeve includes a telescopic frame and a force-bearing frame. The force-bearing frame is installed at the top of the telescopic frame, and several evenly distributed hydraulic cylinders are installed at the bottom of the telescopic frame. The hydraulic end of one hydraulic cylinder is connected to the force-bearing frame on the bottom telescopic sleeve, and the hydraulic end of the other hydraulic cylinder is connected to the force-bearing frame of the adjacent telescopic sleeve. The telescopic frame of the telescopic sleeve is placed inside the telescopic frame of the lower telescopic sleeve. The size of the telescopic sleeve decreases as the telescopic frames are sequentially fitted together, reducing the height. The lower telescopic sleeve is lifted by applying pressure to the force-bearing frame with hydraulic cylinder one. Lifting and lowering are achieved by sliding between the telescopic sleeves. The sliding between adjacent telescopic sleeves is achieved by the hydraulic cylinders installed inside the telescopic frame pushing the force-bearing frame upward. This design enables lifting and lowering actions.

[0009] Preferably, the lifting plate is connected to the hydraulic end of the second hydraulic cylinder inside the telescopic sleeve. The lifting plate is equipped with several evenly distributed balance ropes, one end of which is connected to the lifting plate, and the other end to the force-bearing frame. The lifting plate is mounted on the second hydraulic cylinder of the top telescopic sleeve. After the lifting plate is raised by the second hydraulic cylinder, to ensure its stability, balance ropes are installed at the top corners of the lifting plate. One end of each balance rope is connected to the lifting plate, and the other end is connected to the force-bearing frame of the telescopic sleeve. After the second hydraulic cylinder raises the lifting plate, the lifting plate tightens the balance ropes, stabilizing the lifting plate and applying tension to both sides to ensure its stability. This design improves the stability of the lifting plate.

[0010] Preferably, the rotating assembly includes a rotating disk and a motor. The rotating disk is rotatably connected to the lifting plate. The rotating disk has a meshing groove on the side facing the lifting plate, and a gear ring is mounted on the side of the meshing groove. The motor is mounted on the side of the lifting plate away from the rotating disk. The motor shaft of the motor passes through the lifting plate and is placed in the meshing groove. A gear is mounted on the motor shaft of the motor, and the gear meshes with the gear ring. The rotating disk of the rotating assembly is mounted on the lifting plate and rotatably connected to it. The motor is mounted on the bottom surface of the lifting plate, and its motor shaft passes through the lifting plate and is placed in the meshing groove, driving the gear to rotate. The meshing of the gear with the gear ring drives the rotating disk to rotate. This design enables rotational movement.

[0011] Preferably, a translation plate is mounted on the rotating disk, and a sliding groove is mounted on the translation plate. A sliding block is mounted on the bottom surface of the construction frame. The construction frame is slidably connected to the translation plate through the cooperation of the sliding block and the sliding groove. A sliding cylinder is mounted on the translation plate and is connected to the construction frame. Since the construction frame is mounted on the translation plate on the rotating disk, the rotating disk can drive the translation plate to rotate. The construction frame slides along the sliding groove on the translation plate through the cooperation of the sliding block and the sliding groove. The sliding cylinder is mounted on the translation plate and connected to the construction frame, driving the construction frame to move. This design enables the translation of the construction frame.

[0012] Preferably, a counterweight is installed at the end of the translation plate furthest from the construction frame. To ensure the stability of the translation plate during rotation, a counterweight is installed at the end furthest from the construction frame; this design ensures the stability of the translation plate.

[0013] The beneficial effects of this utility model are: it can expand the construction range, improve stability, realize lifting action, improve the stability of the lifting plate, realize rotation action, realize translation of the construction frame, and ensure the stability of the translation plate.
