DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[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] Please refer to the attached Figure 1 -Attached Figure 6 A road bridge bearing comprises a base plate 1, a leveling structure is arranged on the top surface of the base plate 1, a top plate 2 is arranged above the base plate 1, the leveling structure comprises a mounting shell 201 respectively fixed at the four corners of the top surface of the base plate 1, a rack 202 is slidably inserted inside the mounting shell 201, rotating holes 203 are arranged on both sides of the inner wall surface of the mounting shell 201, a movable rod 204 is rotatably arranged between the two rotating holes 203, a gear 205 is fixed on the outer circular wall surface of the movable rod 204, the gear 205 is meshed with the rack 202, a movable ball 206 is fixed on the top of the rack 202, ball grooves 207 are arranged at the four corners of the bottom surface of the top plate 2, and the movable ball 206 and the ball groove 207 are internally rotatably arranged.

[0024] The cam 302 is located in the tooth groove of the gear 205. The road bridge support, through the setting of the leveling structure, the staff rotates one end of the movable rod 204 in turn to make the gear 205 drive the rack 202 to rise and fall. With the cooperation of the movable ball 206 and the ball groove 207, the corner of the top plate 2 is raised and lowered within a certain range, thereby adjusting the top plate 2 horizontally. When performing the horizontal adjustment, the card plate 302 locks the rotated gear 205 under the action of the hinge, thereby fixing the position of the top plate 2. The operation is convenient, and no nut is required to fix the top plate 2, which is convenient for users to perform horizontal adjustment, improves work efficiency, and ensures the installation quality of the support.

[0025] In the embodiment, baffles 4 are attached to the left and right sides of the bottom plate 1, and enclosures 401 are attached to the front and rear sides of the bottom plate 1. The baffles 4 and the enclosures 401 are slidably arranged, and the top plate 2 is located between the baffles 4 and the enclosures 401. Two movable holes 402 are opened on one side of the enclosure 401, and one end of the movable rod 204 passes through the movable hole 402. The baffles 4 and the enclosures 401 form an enclosure around the top plate 2 and the bottom plate 1, which is convenient for the foundation stone to be formed during concrete pouring. After the foundation stone is solidified, the baffles 4 and the enclosures 401 can be disassembled by sliding the baffles 4 and the enclosures 401, which is convenient for the foundation stone to dry and solidify quickly.

[0026] In the embodiment, an injection hole 101 is opened on the top surface of the top plate 2, and a connecting hole 102 is opened on the top surface of the bottom plate 1. The inner wall surface of the injection hole 101 is an inclined surface. Concrete can be poured between the top plate 2 and the bottom plate 1 through the injection hole 101, so that the foundation stone is formed between the bottom plate 1 and the top plate 2. The connecting hole 102 connects the poured concrete foundation stone with the top surface of the pier, thereby improving the stability of the support installation.

[0027] In the embodiment, a fixing hole 5 is opened on the top surface of the top plate 2, and a rubber pad 501 is fixed inside the fixing hole 5. The bottom surface of the rubber pad 501 is flush with the bottom surface of the top plate 2. The fixing hole 5 allows the bottom surface of the rubber pad 501 to fit with the poured concrete foundation stone, so that the rubber pad 501 can transfer the supporting pressure to the bridge pier through the concrete foundation stone. Two bubble meters 502 are fixed on the top surface of the top plate 2. The two bubble meters 502 are respectively located on both sides of the rubber pad 501. The bubble meter 502 is a prior art and provides a horizontal reference for the staff during the leveling process.

[0028] Working principle: During use, the staff fixes the bottom plate 1 at the designated installation position on the top surface of the pier, and then rotates one end of the movable rod 204 in turn according to the bubble meter 502 to make the gear 205 drive the rack 202 to rise and fall. With the cooperation of the movable ball 206 and the ball groove 207, the corner of the top plate 2 is raised and lowered within a certain range, thereby adjusting the top plate 2 horizontally. Since the card plate 302 and the folding plate 301 are rotatably connected by a hinge, and the hinge is installed on the right side of the card plate 302 and the folding plate 301, when the gear 205 rotates clockwise to control the rack 202 to rise, the card plate 302 is deflected to the right side by the gear 205, which does not affect the clockwise rotation of the gear 205. After the gear 205 rotates clockwise, the card plate 302 locks the gear 205 under the action of the hinge, so that the gear 205 cannot It will rotate counterclockwise and deviate under the action of pressure. When the gear 205 needs to rotate counterclockwise to control the rack 202 to descend, press one end of the movable rod 204. At this time, the spring 3 contracts, and the clamping plate 302 slides out of the tooth groove of the gear 205. Then rotate the gear 205 counterclockwise. After rotation, release the movable rod 204, the spring 3 resets, and the clamping plate 302 enters the tooth groove to lock the gear 205. After horizontal adjustment, concrete can be poured between the top plate 2 and the bottom plate 1 through the injection hole 101, so that the foundation stone is formed between the bottom plate 1 and the top plate 2. The baffle 4 and the enclosure 401 form a fence around the top plate 2 and the bottom plate 1, which is convenient for the foundation stone to be formed during concrete pouring. After the foundation stone is solidified, the baffle 4 and the enclosure 401 are disassembled through the sliding arrangement of the baffle 4 and the enclosure 401, which is convenient for the foundation stone to dry and firm quickly.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
