[0029] Please refer to Figure 1-Figure 7 As shown, the embodiment of the present application provides a roller bracket tooling for supporting a bracket 100 of a double-layer box girder structure bridge, including a card plate 1 and a roller bracket 2, wherein:

[0030] The card board 1 is installed on the bracket 100. The card board 1 is provided with a card slot 11. Two card boards 1 are provided, and the two card boards 1 are respectively provided on both sides of the bracket 100;

[0031] There are two roller brackets 2, and the two roller brackets 2 are connected to the two clamping plates 1 respectively. The roller bracket 2 includes a bracket 21 and at least two bearings 22, and the bearings 22 are rotatably connected to the bracket 21. At least two bearings 22 are arranged below the bracket 21, and the bracket 21 is clamped in the clamping slot 11. Figure 4 As shown, two bearings 22 are illustrated, and the two bearings 22 are respectively arranged at both ends of the bracket 21. Of course, the number of bearings 22 can be set according to the load-bearing requirements, and three or more bearings can be set.

[0032] The roller bracket fixture provided in the embodiment of the present application is installed on the bracket 100 through the clamping plate 1, the bracket 21 is clamped in the clamping slot 11 of the clamping plate 1, and the bearing 22 is arranged below the bracket 21. The movement of the bracket 100 is achieved by rolling the bearing 22 on the ground. The bearing 22 has a high load-bearing capacity and can meet the load-bearing requirements in a smaller size. It is not necessary to lift the bracket 100 to a high distance, avoiding the problem of the bracket 100 being easily overturned due to lifting too high, thereby improving safety.

[0033] In some optional embodiments, the roller bracket 2 further includes at least two mounting shafts 23 and at least two shaft frames 24, the bearing 22 is mounted on the mounting shafts 23, both ends of the mounting shafts 23 are connected to the shaft frames 24, and the shaft frames 24 are mounted below the bracket 21. Figure 4 As shown, the bearing 22 is mounted on the mounting shaft 23 through the shaft hole, and the mounting shaft 23 passes through the bearing 22 and is connected to the shaft frame 24 at both ends. The two shaft frames 24 are mounted at both ends below the bracket 21, and the bearing 22 rotates on the ground, driving the mounting shaft 23 and the shaft frame 24 to move horizontally on the ground, thereby driving the bracket 21 and the bracket 100 connected thereto to move. Of course, the number of the mounting shaft 23 and the shaft frame 24 can be set as needed, consistent with the number of the bearings 22.

[0034] In some optional embodiments, the shaft frame 24 includes a top plate 241 and two side plates 242, the top plate 241 is connected to the bracket 21, the side plates 242 are respectively connected to the lower surface of the top plate 241 and the mounting shaft 23, and the two side plates 242 are symmetrically arranged on both sides of the central axis of the top plate 241. The side plates 242 are respectively connected to the lower surface of the top plate 241 and the mounting shaft 23, and the two side plates 242 are symmetrically arranged on both sides of the central axis of the top plate 241, so that the central axis of the bearing 22 and the top plate 241 coincide, so that the force of the top plate 241 can be evenly transferred to the bearing 22, so that the bearing capacity of the bearing 22 can be maximized, and the reliability and stability of the device are improved.

[0035] In some optional embodiments, the installation shaft 23 includes a first shaft section 231, a second shaft section 232, and a third shaft section 233, which are sequentially arranged. The diameter of the first shaft section 231 and the diameter of the third shaft section 233 are both smaller than the diameter of the second shaft section 232. The second shaft section 232 is used to install the bearing 22, and the first shaft section 231 and the third shaft section 233 are used to install the shaft frame 24. By setting the diameter of the first shaft section 231 and the diameter of the third shaft section 233 to be smaller than the diameter of the second shaft section 232, when the bearing 22 is installed on the second shaft section 232, it is convenient to put it on from any one of the two ends of the installation shaft 23, thereby improving the convenience of installation.

[0036] In some optional embodiments, a shoulder 234 is provided at one end of the second shaft segment 232 close to the first shaft segment 231. By providing the shoulder 234 at one end of the second shaft segment 232 close to the first shaft segment 231, after the bearing 22 is installed on the second shaft segment 232, the shoulder 234 can be used to position and limit the bearing 22, thereby improving the convenience of installation and improving the stability and reliability of the device.

[0037] In some optional embodiments, an annular groove 235 is provided at one end of the second shaft segment 232 close to the third shaft segment 233; the roller bracket 2 further includes a shaft collar 25, which is sleeved on the annular groove 235, and the outer diameter of the shaft collar 25 is greater than the diameter of the second shaft segment 232. By providing the annular groove 235 on the second shaft segment 232, after the bearing 22 is inserted from one end of the third shaft segment 233 and installed on the second shaft segment 232, the shaft collar 25 is sleeved on the annular groove 235 to limit the other end of the bearing 22, thereby improving the stability and reliability of the device.

[0038] In some optional embodiments, the roller bracket tooling further includes a support member 3 disposed on the bracket 100, and the support member 3 is used as a fulcrum for tilting the bracket 100. By arranging the support member 3 on the side of the bracket 100 and using a jack to support the bottom of the support member 3, the bracket 100 is tilted to a certain height, which facilitates the placement of the bracket 21 into the card board 1, improves the convenience of device installation, and improves the reliability and stability of the device.

[0039] In some optional embodiments, the support member 3 includes a bearing plate 31 and a reinforcing plate 32, wherein the bearing plate 31 is perpendicular to the side of the bracket 100, and the reinforcing plate 32 is respectively connected to the bearing plate 31 and the bracket 100. By vertically arranging the bearing plate 31 on the side of the bracket 100, the bearing plate 31 is used as a fulcrum of the jack, and the reinforcing plate 32 is arranged between the bearing plate 31 and the bracket 100, the strength of the bearing plate 31 is increased, thereby improving the reliability and stability of the device.

[0040] In some optional embodiments, the roller bracket tooling further includes a baffle 4, which is mounted on the card plate 1 and located above the card slot 11, and is used to abut against the bracket 21. By welding the baffle 4 on the card plate 1, the baffle 4 abuts against the bracket 21, thereby preventing the bracket 21 from sliding in the horizontal direction, thereby improving the stability and reliability of the device.

[0041] In some optional embodiments, the cross section of the card slot 11 is rectangular, and the bracket 21 is made of square steel. The cross section of the card slot 11 is set to be rectangular, and the bracket 21 is made of square steel. The bracket 21 is embedded in the card slot 11. The square steel material is light in weight and can ensure strength, which can reduce costs.

[0042] The working principle of the roller bracket tooling proposed in the utility model is: the bracket 100 is installed on the bracket 100 through the clamping plate 1, the bracket 21 is clamped in the clamping groove 11 of the clamping plate 1, and the bearing 22 is arranged below the bracket 21. The movement of the bracket 100 is achieved by the rolling of the bearing 22 on the ground. The bearing 22 has a high load-bearing capacity and can meet the load-bearing requirements in a smaller size. There is no need to lift the bracket 100 to a high distance, which avoids the problem of the bracket 100 being easy to overturn due to lifting too high, thereby improving safety.
