Description

Technical Field

[0001] The utility model relates to the technical field of bridge installation, in particular to a Bailey bracket and a vase pier column docking device. Background Art

[0002] After searching, the Chinese patent announcement number is CN217174345U, which discloses a steel tube Bailey beam-column bracket and pier column connection device. The limitations of the existing Bailey bracket and vase pier column docking device mainly focus on its adaptability and precision control. First, it is difficult to flexibly adapt to the diverse pier column sizes and lacks versatility and adjustability. Second, the precision control during the docking process is not accurate enough, and it is difficult to ensure the tight fit and structural safety of each docking. Specifically, these devices are often fixed in design and do not fully consider the diversity of pier column size changes in engineering practice. As a result, when facing vase pier columns of different specifications, it is necessary to frequently replace or customize accessories, which increases construction difficulty and cost. Utility Model Content

[0003] The purpose of the present utility model is to provide a device for connecting a Bailey bracket to a vase pier in order to solve the above-mentioned problem.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for docking a Bailey bracket and a vase pier column, comprising: a main body, a rotating shaft is provided below the main body, a rotating disk is provided below the rotating shaft, a lower inward arc groove is provided below the rotating disk, an inward rod is slidably connected in the lower inward arc groove, a pier column clamping block is fixedly connected to the bottom of the inward rod, a threaded hole is provided on the side of the pier column clamping block, a screw rod is fixedly connected to the top of the inward rod, a fixing nut is screwed on the top of the screw rod, a yield groove is provided on the side of the main body, a shift rod is fixed to the side of the rotating disk, and an upper inward arc groove is provided above the main body.

[0005] As a further solution of the present invention: a Bailey bracket fixing plate is provided above the main body, a bottom plate is fixedly connected to the side of the Bailey bracket fixing plate, and a side plate is fixedly connected to the top of the Bailey bracket fixing plate.

[0006] As a further solution of the present invention: the lower inward arc groove, the inward arc rod, the pier clamping block, the threaded hole, the screw rod, the fixing nut and the upper inward arc groove are all provided in three groups, the sizes of the lower inward arc groove and the upper inward arc groove are adapted to each other, the inward arc rod is adapted to the lower inward arc groove, and the screw rod is adapted to the upper inward arc groove.

[0007] As a further solution of the present invention: the three groups of inward-retracting rods are connected by high-strength elastic bands, and the threaded holes are used to fix the pier columns with bolts.

[0008] As a further solution of the present invention: the bottom plate is mounted on the main body by bolts, and the side plates are mounted on the Bailey brackets by bolts.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model is designed with three sets of lower and upper inward arc grooves, as well as corresponding inward arc grooves, pier clamping blocks, threaded holes, screw rods and fixing nuts. Each set can be adjusted independently to adapt to vase piers of different diameters, thus improving the problem that the existing Bailey bracket and vase pier docking device is difficult to flexibly adapt to various pier sizes.

[0011] By rotating the rotating disk through the lever, the inner rod in the lower inner arc groove slides along the groove to the appropriate position. Since the inner rods are connected by high-strength elastic bands, they can move synchronously, ensuring the synchronous adjustment of the three sets of clamping mechanisms. This improves the problem of insufficient precision control in the docking process of the existing Bailey bracket and vase pier column docking device, making it difficult to ensure a perfect fit and structural safety every time.

[0019] Reference Figures 1 to 4The present invention also provides a kind of docking device of Bailey bracket and vase pier column, comprising: a main body 1, a rotating shaft 2 is provided at the bottom of the main body 1, a rotating disk 3 is provided at the bottom of the rotating disk 3, a lower inner arc groove 4 is provided at the bottom of the rotating disk 3, an inner rod 5 is slidably connected to the lower inner arc groove 4, a pier column clamping block 6 is fixedly connected to the inner rod 5 below, a threaded hole 7 is provided on the side of the pier column clamping block 6, a screw rod 8 is fixedly connected to the upper part of the inner rod 5, a fixing nut 9 is screwed on the upper part of the screw rod 8, a yield groove 10 is provided on the side of the main body 1, a shift rod 11 is fixedly connected to the side of the rotating disk 3, an upper inner arc groove 12 is provided on the top of the main body 1, and the lower inner arc groove 4, the inner rod 5, the pier column clamping block 6, the threaded hole 7, the screw rod 8, the fixing nut 9 and the upper inner arc groove 12 are all provided in three groups, and the size of the lower inner arc groove 4 and the upper inner arc groove 12 is adapted to each other. Matching with the lower inner arc groove 4, the screw rod 8 is matched with the upper inner arc groove 12, and the three groups of inner rods 5 are connected by high-strength elastic bands. The threaded holes 7 are used to fix the pier with bolts. The rotating disk 3 is rotated by the lever 11 to make the inner rod 5 in the lower inner arc groove 4 slide along the groove to the appropriate position. Since the inner rods 5 are connected by high-strength elastic bands, they can move synchronously to ensure the synchronous adjustment of the three groups of clamping mechanisms. The pier clamping block 6 below the inner rod 5 directly contacts and clamps the vase pier. By rotating the screw rod 8, the screw rod rises or falls in the threaded hole 7, pushing the inner rod 5 and the clamping block 6 to tighten inward or loosen outward, thereby achieving a firm clamping of the pier. The design of the threaded hole 7 allows the use of bolts to further strengthen the connection between the pier and the clamping block 6, thereby improving the stability and safety of docking.

[0020] Reference Figure 1 A Bailey bracket fixing plate 13 is provided above the main body 1, and a bottom plate 14 is fixed to the side of the Bailey bracket fixing plate 13. A side plate 15 is fixed above the Bailey bracket fixing plate 13. The bottom plate 14 is installed above the main body 1 by bolts, and the side plate 15 is installed on the Bailey bracket by bolts. The main body 1 serves as the foundation of the entire device and is firmly installed in the designated position through the bottom plate 14 and bolts. The Bailey bracket is fixed to the Bailey bracket fixing plate 13 through the side plate 15 and bolts to achieve connection with the main body.

[0021] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0022] The working principle of the present invention is as follows: the main body 1 is used as the basis of the entire device and is firmly installed in the designated position through the bottom plate 14 and bolts. The Bailey bracket is fixed to the Bailey bracket fixing plate 13 through the side plate 15 and bolts to achieve connection with the main body. The device is designed with three groups of lower inner arc grooves 4 and upper inner arc grooves 12, as well as corresponding inner arc rods 5, pier column clamping blocks 6, threaded holes 7, screw rods 8 and fixing nuts 9. Each group can be adjusted independently to adapt to vase piers of different diameters. When it is necessary to dock piers of different sizes, first rotate the rotating disk 3 by the lever 11 to make the inner arc rod 5 in the lower inner arc groove 4 slide along the groove to the appropriate position. The rotating disk 3 cooperates with the inner arc groove 4 to drive the three groups of inner arc rods 5 to move synchronously to tighten or loosen. The pier column clamping block 6 under the inner arc rod 5 directly contacts and clamps the vase pier. By rotating the nut 9, the inner arc rod 5 and the clamping block 6 are pushed inward to tighten or loosen outward, and the inner arc rod 5 is tightened. It is fixed at any position of the lower inner arc groove 4, so as to achieve a firm clamping of the pier column. The design of the threaded hole 7 allows the use of bolts to further strengthen the connection between the pier column and the clamping block 6, thereby improving the stability and safety of the docking. The upper inner arc groove 12 matches the size of the lower inner arc groove 4 to ensure that the screw rod 8 can smoothly pass through the upper inner arc groove 12 during the rising process. After the adjustment is completed, the nut on the screw rod below the shift rod 11 is tightened to avoid shaking or offset, thereby ensuring the accuracy of the docking. The clearance groove 10 on the side of the main body 1 provides sufficient operating space for the shift rod 11, which is convenient for construction personnel to easily adjust the rotating disk 3 to achieve fast and accurate docking. The device is firmly connected to the Bailey bracket fixing plate 13, the bottom plate 14 and the side plate 15 with the Bailey bracket and the main body to form an overall stable structural system. This design not only enhances the load-bearing capacity of the device, but also improves its stability and reliability in complex construction environments.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
