Description

Technical Field

[0001] The utility model relates to a reinforcement structure, in particular to a road bridge crack reinforcement structure for preventing displacement. Background Art

[0002] Road bridges are generally composed of several parts, such as roadbed, pavement, bridge, tunnel engineering and traffic engineering facilities. After a certain period of use, the concrete structure of the bridge will age and cracks will appear. The cracks have little impact on the road bridge in the early stage. With the changes in the environment and long-term use, the cracks will develop rapidly, deteriorate, and even suddenly damage. Therefore, it is necessary to repair and reinforce the road bridge in time to extend the service life of the bridge;

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-5 The utility model provides a technical solution for a road bridge crack reinforcement structure to prevent displacement: it includes an installation box 3, the bottom ends of the left and right sides of the installation box 3 are fixedly connected to the opposite surfaces of two installation plates 7 respectively, the bottom surfaces of the installation box 3 and the two installation plates 7 are overlapped with the bottom surface of the foundation pit 2 opened on the bridge body 1, the two installation plates 7 are respectively located on both sides of the crack 4, and the interior of the installation box 3 is provided with a reinforcement mechanism 6 and the reinforcement mechanism 6 is connected to the foundation pit 2.

[0024] A plurality of mounting holes 8 are provided in each mounting plate 7, and the plurality of mounting holes 8 are respectively socketed with the upper ends of a plurality of bolts 9, and the bottom ends of the plurality of bolts 9 are connected to the bottom surface of the foundation pit 2. When using the device to reinforce cracks in a road or bridge, the user first excavates the foundation pit 2 around the crack 4, and then places the device into the foundation pit 2 so that the two mounting plates 7 are respectively located on both sides of the crack 4, and then the user drives the bolts 9 into the foundation pit 2 to fix the device.

[0025] The reinforcement mechanism 6 includes two fixing plates 61, the bottom surfaces of the two fixing plates 61 are fixedly connected to the lower inner side surface of the installation box 3, and the middle parts of the two fixing plates 61 are rotationally connected to the optical axes on both sides of the screw 613 through rolling bearings.

[0026] The lead screw 613 is provided with two sections of threaded grooves with opposite spiral directions, and the two sections of the threaded grooves on the lead screw 613 are respectively threadedly connected with the two threaded holes 616 provided on the two translation blocks 614. The two translation blocks 614 are also provided with sleeve holes 615, and the two sleeve holes 615 are sleeved with a slide rod 617. The two ends of the slide rod 617 are respectively fixedly connected with the opposite surfaces of the two fixed plates 61. By providing the sleeve holes 615 on the translation block 614 and arranging the slide rod 617 to be sleeved with the sleeve holes 615, the movement of the translation block 614 is limited by the connection between the slide rod 617 and the sleeve holes 615, thereby preventing the translation block 614 from rotating when the lead screw 613 rotates and affecting its translation.

[0027] The outer side surfaces of the two translation blocks 614 are fixedly connected to the opposite ends of the two connecting frames 611, and the opposite ends of the two connecting frames 611 are rotationally connected to the opposite ends of the two drill rods 610 through rolling bearings. The opposite ends of the two drill rods 610 pass through two through holes 5 and are connected to the foundation pit 2. The two through holes 5 are respectively opened on the front and rear sides of the installation box 3.

[0028] The optical axes at the opposite ends of the two drill rods 610 are respectively fixedly connected to the two sprocket wheels 4 618, which are respectively connected to the two sprocket wheels 2 68 through chains. The two sprocket wheels 2 68 are respectively fixedly connected to the optical axes at the opposite ends of the two sliding rods 67. The optical axes at the opposite ends of the two sliding rods 67 are respectively connected to the upper ends of the two fixed plates 2 69 through rolling bearings. The bottom ends of the two fixed plates 2 69 are respectively fixedly connected to the upper surfaces of the two connecting frames 611. When the lead screw 613 rotates, the connecting frame 611 and the drill rod 610 are driven to translate through the translation block 614. At this time, the connecting frame 611 drives the sliding rod 67 to slide along the sleeve 62 through the fixed plate 2 69, thereby utilizing the sliding of the sliding rod 67 in the sleeve 62 to maintain the transmission of the sleeve 62 and the drill rod 610 so that the drill rod 610 continues to rotate.

[0029] The opposite ends of the two sliding rods 67 are both sleeved with the inside of the sleeve 62, and the sleeve 62 is rotatably connected to the upper ends of the two fixed plates 61 through rolling bearings. The inner wall of the sleeve 62 and the opposite ends of the two sliding rods 67 are all arranged in a straight line.

[0030] The middle part of the sleeve 62 is fixedly connected to the bevel gear 1 63 and the sprocket 1 66 at the same time. The sprocket 1 66 is connected to the sprocket 3 612 through a chain. The bevel gear 1 63 is meshed with the bevel gear 2 65. The bevel gear 2 65 is fixedly connected to the bottom end of the rotating shaft 64. The rotating shaft 64 is rotatably connected to the upper surface of the installation box 3 through a rolling bearing. The rotating shaft 64 is connected to the sleeve 62 through the bevel gear 1 63 and the bevel gear 2 65. It is convenient for the user to use the rotating shaft 64 to control the rotation of the sleeve 62 to install the device.

[0031] The operating steps of the utility model are:

[0032] When using the device to reinforce cracks in road bridges, the user first excavates a foundation pit 2 around the crack 4, and then places the device into the foundation pit 2 so that the two mounting plates 7 are respectively located on both sides of the crack 4, and then the user drives the bolts 9 into the inside of the foundation pit 2 to fix the device, and rotates the rotating shaft 64 to use the bevel gear 1 63, bevel gear 2 65, rotating drum 62, rotating rod 67, sprocket 2 68, and sprocket 4 618 to drive the two drill rods 610 to rotate. When the rotating drum 62 rotates, it drives the lead screw 613 to rotate forward through the sprocket 1 66 and sprocket 3 612. When the lead screw 613 rotates forward, it drives the two drill rods 610 away from each other through the threaded hole 616, the translation block 614 and the connecting frame 611, so that the two drill rods 610 translate and rotate at the same time. At this time, the two drill rods 610 respectively pass through the two through holes 5 and drill into the inside of the foundation pit 2 to further fix the device, and then the user can pour concrete into the foundation pit 2 to fill and repair the foundation pit 2 and the crack 4.
