[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figures 1 to 4 The utility model provides a technical solution: an adjustable bridge support device, comprising: an arc-shaped fixing member 1, an edge rib plate 3, a receiving groove 4, a supporting mechanism and a positioning mechanism. The number of the arc-shaped fixing members 1 is two, and the ends are respectively provided with fixing strips 2, and the fixing strips 2 are detachably connected by bolts and nuts; the two edge rib plates 3 are respectively arranged on the outer sides of the outer walls of the two arc-shaped fixing members 1; the two receiving grooves 4 are respectively opened on the two edge rib plates 3; the supporting mechanisms are respectively rotatably arranged on the two edge rib plates 3; the positioning mechanism is arranged on the two fixing strips 2.
[0019] In the specific implementation process, it should be noted that the longitudinal beam is wrapped between the two arc-shaped fixing parts 1, and is installed on the fixing strip 2 with bolts and nuts for detachable connection. By controlling the support mechanism, the support angle can be adjusted according to actual needs, thereby achieving support for the crossbeam to adapt to different crossbeam angle support requirements. The positioning mechanism is set on the two fixing strips 2, which is used to further reinforce the connection between the crossbeam and the longitudinal beam, effectively ensuring the stability of the bridge structure. The support mechanism and the positioning mechanism in this device are modularly designed, which is convenient for combining the positioning mechanism with the support mechanism. At the same time, the positioning mechanism can be disassembled according to actual conditions, which improves the efficiency of installation and maintenance, and also extends the service life of the equipment, which not only ensures the stability of the bridge structure, but also improves the flexibility and convenience of construction.
[0020] In some examples, further, an inclined groove is provided in the middle portion of two adjacent fixing bars 2 .
[0021] In some examples, further, the supporting mechanism includes: a supporting plate 5, a pad 6 and an adjusting assembly, one end of the two supporting plates 5 is rotatably installed on the top of the two receiving grooves 4; the two pads 6 are respectively arranged on the surfaces of the two supporting plates 5; the adjusting assembly is arranged on the other end of the two receiving grooves 4 and the supporting plate 5.
[0022] During the specific implementation process, it should be noted that one end of the two support plates 5 can be rotated so that the adjustment component can be controlled to flexibly adjust according to the specific needs of the bridge construction. The pad 6 is used to increase the support area and disperse the pressure, thereby avoiding direct local pressure on the beam. The staff can control the adjustment component in a rotating manner so that the adjustment component controls and adjusts the support angle of the support plate 5 to achieve the purpose of precise support of the beam. By operating the adjustment component, the positioning and angle adjustment of the support plate 5 can be completed quickly and efficiently to ensure the stability of the bridge structure and the safety of construction.
[0023] In some examples, further, the adjustment assembly includes: a threaded rod 7 and an internally threaded sleeve 8, the number of the threaded rods 7 is multiple, the ends of some of the threaded rods 7 are detachably arranged at the bottom ends of the two receiving grooves 4 by screws and nuts, and the ends of other parts of the threaded rods 7 are rotatably installed on the ends of the two support plates 5, and the threads of two adjacent threaded rods 7 are symmetrically distributed; the two internally threaded sleeves 8 are respectively screwed on the outside of the outer walls of the two adjacent threaded rods 7.
[0024] During the specific implementation process, it should be noted that by rotating the internal threaded sleeve 8, the threaded rod 7 can be driven to move along its axial direction, thereby changing the angle of the support plate 5, so that the staff can control the support angle of the bridge in a fine-tuning manner to ensure the stability of the structure and the safety of construction. The threaded rod 7 is detachable, which greatly improves the flexibility and ease of use of the adjustment component. When support is not needed, the threaded rod 7 can be removed from the storage groove 4, and then the support plate 5 can be retracted into the storage groove 4.
[0025] In some examples, further, the positioning mechanism includes: an insertion rod 9, a shell 10, a positioning nut 11, a fastening assembly and a steel belt 12, the two insertion rods 9 are respectively inserted into the fixing strip 2 located on the same side, and threads are respectively provided at both ends; the shell 10 itself is provided with a plurality of protrusions, and is sleeved on the outer side of the outer wall of the two insertion rods 9 through the protrusions; a plurality of positioning nuts 11 are respectively screwed on the threads at both ends of the two insertion rods 9 in a group of two; the fastening assembly is arranged inside the shell 10; one end of the steel belt 12 is detachably overlapped at the inclined groove, and the other end is connected to the fastening assembly.
[0026] During the specific implementation process, it should be noted that the positioning mechanism of the adjustable bridge support device has the following working process: the threads set at both ends of the insertion rod 9 are convenient for installing the positioning nut 11, and the positioning nut 11 can be flexibly moved so that the shell 10 can be centered between the two arc-shaped fixing parts 1. The fastening assembly is used to control the tightness of the steel belt 12, so that the connection of the bridge structure is more stable. When the cross beam and the longitudinal beam are in an inclined state, whether to use the positioning mechanism can be determined according to actual usage requirements.
[0027] In some examples, further, the fastening assembly includes: a worm 13, a winding column 14 and a worm wheel 15, the worm 13 is rotatably arranged inside the shell 10, and a handle is also installed at the end; the two ends of the winding column 14 are rotatably installed inside the shell 10, located at the top of the worm 13, and perpendicular to the worm 13, and the middle part of the winding column 14 is fixedly connected to the other end of the steel belt 12; the worm wheel 15 is mounted on the outside of the outer wall of the winding column 14, and matches the worm 13.
[0028] In the specific implementation process, it should be noted that the staff rotates the handle of the worm 13, and the worm 13 rotates accordingly. The rotation of the worm 13 drives the matching worm wheel 15, so that the winding column 14 rotates synchronously, thereby causing the steel belt 12 fixed in the middle part of the winding column 14 to produce a tightening or relaxing effect. During operation, the staff continuously adjusts the rotation of the handle of the worm 13 according to the stability requirements of the bridge support until the steel belt 12 and the beam are more tightly fastened, thereby achieving a stable positioning of the bridge structure. After the steel belt 12 is tightened to an appropriate degree, the rotation of the handle of the worm 13 is stopped to complete the fixation of the bridge structure, thereby ensuring the stability and safety of the entire structure during the construction process. Through the control of the worm 13, the tightening operation of the steel belt 12 is achieved in a convenient, efficient and precise manner.
