Description

Technical Field

[0001] This invention relates to the field of bridge construction equipment technology, specifically to a bridge construction support structure. Background Technology

[0002] During bridge construction, various support equipment is needed to support the bridge structure, thereby improving the overall stability of the structure during subsequent construction.

[0003] For example, the utility model patent disclosed in patent number CN207987759U discloses a support structure for bridge construction. The structure includes a connecting plate, a fixing block, a left support column, a crash ring, a connecting block, a left support column, a right support column, and a right support column. The lower surface of the connecting plate is mounted on the upper surface of the fixing block and welded parallel to each other. The lower surface of the fixing block is mounted on the upper surface of the left support column and welded perpendicularly. The outer surface of the left support column is in contact with the inner surface of the crash ring. The left support column is embedded in the lower surface of the connecting block with a clearance fit. This utility model provides a support structure for bridge construction, connecting the connecting plate to the bridge and providing fixed support with the left and right support columns. When a ship collides with the outer steel ring, the outer steel ring exerts a force on the upper limit block of the support rod, the support rod exerts a force on the limit rod, and the limit rod exerts a force on the spring. The spring and the rubber ring generate a rebound force, balancing the force exerted by the ship. The support column has good anti-collision function, is not easily damaged, and has high practicality.

[0004] For example, the utility model patent disclosed in patent number CN217352162U discloses a support structure for bridge construction, including a wall, several columns, support members, and connectors. The connectors are node plates. The support members include wall ties, horizontal bracing, and scissor braces. Several columns are arrayed on one side of the wall, and several node plates are disposed around the perimeter of the columns. The horizontal bracing is disposed between adjacent columns and connected to the columns via the node plates. The plane of the node plates is parallel to the axial direction of the columns. One end of the wall ties is connected to the column via the node plate, and the other end is connected to the wall. The scissor braces are disposed between the columns and the wall and connected to the columns via the node plates. This application has the effect of improving construction efficiency when building the support structure.

[0005] Although the aforementioned patents can provide support for the construction of bridges, the equipment is a fixed structure, which makes it difficult to adjust the support area and force according to the user's needs, thus reducing the adaptability of the equipment. Therefore, a bridge construction support structure is needed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a bridge construction support structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bridge construction support structure, comprising an active bevel gear, an adjustment device, a first support plate, a fixed slide groove, a limiting guide groove, a support clamping seat, a second support plate, a limiting angle support plate, a transmission ball screw, a driven bevel gear, and a reduction motor.

[0008] A second support plate for limiting is fixedly installed at the center of the lower end face of the first support plate, and is fixedly connected to the first support plate and the second support plate by two sets of limiting angle support plates. A reduction motor for transmission is provided at the center of the rear end face of the first support plate, and a driving bevel gear is rotatably engaged at the center of the front end face of the first support plate. Four sets of support engagement seats are equidistantly arranged in a ring around the driving bevel gear at the center of the front end face of the first support plate. A transmission ball screw is rotatably engaged inside two sets of support engagement seats located on the same horizontal line, and a driven bevel gear for transmission is provided at the center of the inner end face of the transmission ball screw. Four sets of fixed sliding grooves are equidistantly opened on the inner end face of the first support plate, and limiting guide grooves are opened on the side end faces of the four sets of fixed sliding grooves. An adjustment device is provided on the inner end face of the first support plate through the limiting guide grooves.

[0009] Specifically, the control device includes a guide device, a threaded guide groove, a limiting slide, a connecting bracket, a driven transmission gear, a servo motor, a driving transmission gear, and a guide slide. The upper end face of the guide slide is provided with a limiting slide for limiting, and a threaded guide groove is provided near the middle of the inner end face of the limiting slide. A connecting bracket for support is provided on the lower end face of the guide slide. The driven transmission gear is rotatably engaged near the middle of the inner end face of the connecting bracket, and the driving transmission gear is rotatably engaged near the bottom of the inner end face of the connecting bracket. A servo motor is provided on the rear end face of the connecting bracket opposite the driving transmission gear. The guide device is threadedly slidably connected to the inner end face of the connecting bracket through the driven transmission gear.

[0010] Specifically, the guiding device includes a stepper motor, a driving guide gear, a driven guide gear, a pressing device, a connecting turntable, a positioning groove, a limiting support, a guide slide shaft, a threaded guide shaft, and a limiting baffle. A threaded guide shaft is fixedly installed at the center of the upper end face of the limiting baffle, and guide slide shafts are symmetrically arranged on the upper end face of the limiting baffle with the threaded guide shaft as the center. A limiting support is fixedly installed on the upper end face of the guide slide shaft and the threaded guide shaft. Four sets of positioning grooves are equidistantly opened on the upper end face of the limiting support. A driven guide gear is rotatably engaged at the center of the inner end face of the limiting support, and a driving guide gear is arranged on the inner end face of the limiting support near the driven guide gear. A stepper motor is arranged on the lower end face of the limiting support opposite the driving guide gear. Four sets of pressing devices are equidistantly engaged on the upper end face of the limiting support through the connecting turntable.

[0011] Specifically, the pressing device includes a connecting top plate, spring support shafts, a fixed slider, and a positioning pin shaft. A positioning pin shaft is fixedly installed at the center of the lower end face of the fixed slider, and spring support shafts are equidistantly arranged at the four corners of the upper end face of the fixed slider. A connecting top plate is fixedly installed on the upper end face of the four sets of spring support shafts.

[0012] Specifically, the inner end face of the connecting turntable is provided with four sets of arc-shaped grooves at equal intervals, and the fixed slider is slidably engaged with the positioning pin shaft through the arc-shaped grooves. The arc-shaped grooves can provide centripetal power to the positioning pin shaft, thereby improving the stability of the displacement of the top pressing device inside the limiting support.

[0013] Specifically, the fixed slider is slidably engaged inside the limiting support through the positioning groove, and the active guide gear and the driven guide gear are meshed together, which can effectively improve the stability of the active guide gear transmitting power to the connecting turntable through the driven guide gear.

A support base for limiting is fixedly installed on the lower end face of the four sets of spring buffer shafts.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This invention, by setting up an active bevel gear, a transmission ball screw, and a driven bevel gear, enables the geared motor to synchronously drive four sets of driven bevel gears to rotate when supporting building surfaces of different sizes. The four sets of driven bevel gears can then synchronously drive four sets of control devices to move outward via the transmission ball screw, thereby providing adaptive support for buildings of different sizes and improving the practicality of the equipment.

[0020] 2. By setting up a control device, this invention allows for precise control of the support distance and area of ​​different buildings. A servo motor drives a driven gear via an active transmission gear, which in turn drives the overall guiding device to move forward and backward via a threaded guide shaft. Simultaneously, a stepper motor provides power to the connecting turntable via the active and driven guide gears, enabling the turntable to synchronously move four sets of top-pressing devices outward. This increases the support area for different buildings and improves the stability of the support. Attached Figure Description
