Description

Technical Field

[0001] The utility model relates to the technical field of support adjustment devices, in particular to a bridge support adjustment device used in bridge engineering construction. Background Art

[0002] Bridge engineering refers to the process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology that studies this process. It is a branch of civil engineering. The development of bridge engineering mainly depends on the needs of transportation. Bridge construction is the process of building a bridge according to the design content. It mainly refers to bridge construction technology and construction organization, construction management, construction quality and other contents. The bridge is formed by connecting multiple sections of the bridge body. Therefore, during construction and repair, in order to stabilize the bridge body and prevent collapse caused by external vibration, bridge construction support devices are often used. Bridge support devices are a commonly used auxiliary tool in the process of bridge construction as a support and protection for the facility.

[0003] The existing bridge construction support device provides good support for the bridge body, but the device itself is unstable. Due to its insufficient support, it is easy to deviate from the support point when it is subjected to the feedback force of the bridge body. In addition, the supporting force of the bridge body by the existing bridge support device cannot change according to the shape of the bridge body, resulting in the support device after deviation failing to maintain support at important parts of the bridge body, thereby affecting the stability of the entire bridge. For this reason, we propose a bridge support adjustment device for bridge engineering construction. Utility Model Content

[0006] Furthermore, the support plate and the support rod are symmetrically distributed along the two ends of the telescopic frame, and the support plate forms a telescopic structure with the telescopic frame through a cylinder.

[0007] Furthermore, the support piles are symmetrically distributed along the top and bottom ends of the support rod, and the middle end of the support rod is axially connected to the support plate.

[0008] Furthermore, the driving motor comprises a motor, and a driving gear is connected to the bottom end of the motor, a gear ring is attached to one side of the driving gear, and support rods are connected to the inner walls around the gear ring.

[0009] Furthermore, the gear ring forms a transmission structure through a driving gear and a motor, and the gear ring and the support rod are integrally fixedly connected.

[0010] Furthermore, the support seat includes a seat plate, the bottom end of the seat plate is fixedly connected to a support pile, and the top end of the seat plate is connected to an anti-slip sheet, and the top surface of the anti-slip sheet is provided with an adsorption groove.

[0011] Furthermore, the anti-skid sheet is fitted in a ring shape around the top surface of the seat plate, and the adsorption grooves are distributed in a concave ring shape along the center of the anti-skid sheet.

[0012] Compared with the prior art, the beneficial effect of the utility model is that this support adjustment device relies on the combination of the support rods at both ends and the driving motor to form a rotational adjustment of the overall structure. Cooperating with the telescopic support structure, it can not only maintain the stability of the bridge support adjustment process, but also maintain the flexibility of the telescopic process through the telescopic frame structure at the middle end, which is convenient for adjustment corresponding to different support points and reduces the offset phenomenon caused by the support process.

[0013] The motor drives the driving gear and the meshing gear ring, so that the support rod and the support plate part fixedly connected to the gear ring can realize the axial rotation process, which assists the stable adjustment process. In addition, the device is provided with motor transmission parts at both ends, with a large adjustable range and high flexibility.

[0014] This seat plate fits partially with the bridge structure, and the soft rubber anti-slip sheet on the surface of the seat plate is used to improve the friction of the fit. At the same time, the adsorption groove is used to maintain a certain adsorption, thereby further improving the stability of the supporting process of this supporting device.
