The anti-drop beam block is divided into two parts, one part is embedded in the box girder and installed when the box girder is cast, and the other part is connected to the embedded part by bolts after the box girder is erected. The interference between the anti-drop beam block and the anti-drop beam can prevent the box girder from moving laterally. Usually, four anti-drop beam blocks need to be installed at the bottom of a box girder. Since the distance between the bottom of the box girder and the groove of the bridge pier is very small, and the distance between the bottom of the beam and the top surface of the pier is also very small, and the height of the anti-drop beam block itself is only slightly smaller than the distance between the bottom of the beam and the top surface of the pier, in such a narrow installation space, if there is no special installation tool, the installation of the above-mentioned heavy and irregularly shaped anti-drop beam blocks is costly and the installation speed is very slow. Summary of the invention

[0017] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific working process are given, but the protection scope of the utility model is not limited to the following embodiment.
[0018] The utility model discloses a quick installation device for an anti-falling beam stopper, which is suitable for an anti-falling beam stopper of a T-shaped structure. The top plate thereof has a larger size and is used for connecting the embedded plate at the bottom of the box beam. The bottom plate has a smaller size and is T-shaped as a whole.
[0019] like Figure 1-5 As shown, it includes a support frame 1, a pair of horizontal support arms 2 extending along the bridge direction are arranged on the top of the support frame 1, a plurality of cross-bridge pulleys 3 are arranged on the top of the horizontal support arms 2, and a first bridge-direction pulley 4 is arranged at the bottom of the free end of the horizontal support arm 2; a vertical support leg 5 is also arranged on the support frame 1, a height adjustment mechanism is arranged on the vertical support leg 5, and a second bridge-direction pulley 6 is arranged at the bottom of the vertical support leg 5.
[0020] Specifically, the support frame 1 adopts a vertically arranged rectangular frame, and a vertical leg 5 is welded to each of the two ends of the bottom of the rectangular frame. In this embodiment, the vertical leg 5 adopts a sleeve structure (i.e., a height adjustment mechanism) with a locking member 7, and the height of the vertical leg 5 can be adjusted as needed. In addition to the above structure, the height adjustment mechanism can also adopt other common forms. When in use, the vertical leg 5 is located in the pier top groove K area. In order to facilitate movement, a second bridge pulley 6 is installed at the bottom of each vertical leg 5.
[0021] The horizontal support arm 2 is made of channel steel with the notch facing upwards, and the two arms are arranged in parallel, one end is welded to the top two sides of the support frame 1, and the other end (i.e., the free end) forms an opening structure for convenient entry and exit of the anti-falling beam block 8. The free end of the horizontal support arm is located above the pad stone N, and a first longitudinal pulley 4 connected to the top surface of the pad stone N is installed at the bottom.
[0022] The horizontal support arms 2 are used to support the anti-falling beam stopper M. When in use, the top plate of the T-shaped anti-falling beam stopper M is lifted by the two horizontal support arms 2, and the lower structure of the anti-falling beam stopper M is located between the two horizontal support arms 2. Therefore, the spacing of the horizontal support arms 2 should be designed according to the specific size of the anti-falling beam stopper M, and the maximum should not exceed the length of the top plate of the anti-falling beam stopper M along the bridge direction, and the minimum should not be less than the length of the lower structure of the anti-falling beam stopper M along the bridge direction.
[0023] In order to facilitate the adjustment of the transverse bridge position of the anti-falling beam stopper M, a transverse bridge pulley 3 is also installed on the top surface of the horizontal support arm 2. The transverse bridge pulleys 3 on the two horizontal support arms 2 are located in corresponding positions and are arranged at the same interval, and the interval between adjacent transverse bridge pulleys 3 is less than the transverse bridge length of the top plate of the anti-falling beam stopper M.
[0024] Furthermore, in order to enhance the overall stability of the device, a reinforcing diagonal brace 9 is provided between the horizontal support arm 2 and the vertical support leg 5 on the same side.
[0025] When in use, the first longitudinal pulley 4 is connected to the pad stone N, and the second longitudinal pulley 6 is connected to the pier top groove K. The horizontal support arm 2 is kept horizontal by adjusting the height of the vertical support leg 5; the anti-drop beam block M is placed on the horizontal support arm 2, and according to the installation position of the anti-drop beam block 8, the frame is first pushed to adjust the longitudinal position of the overall device, and then the anti-drop beam block M is moved along the transverse pulley 3 to adjust the transverse position of the anti-drop beam block M; after the adjustment is in place, the anti-drop beam block M is installed on the embedded plate at the bottom of the box beam. After the installation is completed, first push the frame to move it along the transverse direction of the bridge, so that the horizontal support arm 2 leaves the anti-drop beam block M, and then push the frame to move it along the longitudinal direction of the bridge, and follow the above steps to install the next anti-drop beam block.
[0026] The utility model has a compact structure and is easy to adjust. It can not only adapt to the narrow installation space at the bottom of the box beam, but also can conveniently and accurately adjust the position of the anti-falling beam stopper, thereby improving the installation speed and quality, effectively saving manpower and material resources, and reducing installation costs.
[0027] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships, such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", "outside", etc., are based on the orientation or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
