[0029] Embodiment 1

[0030] This embodiment provides a flange bolt synchronous disassembly and assembly device, as shown in the attached Figure 1 and attached Figure 2 As shown, it includes a fixed disk 1, multiple rotating shafts 2 rotatably arranged on the fixed disk, a driven gear 3 arranged on the rotating shaft 2 in the fixed disk 1, and a driving gear 4 rotatably arranged in the fixed disk 1 and meshing with each of the driven gears 3. The bottom of the rotating shaft 2 is connected to a sleeve 5. A power device (which can be an electric wrench) drives the driving gear to drive each driven gear, thereby driving each rotating shaft and sleeve to rotate, so as to achieve synchronous disassembly and assembly of multiple bolts. In order to solve the problem that the nut orientation of each bolt is not uniform and needs to be manually adjusted to be consistent before the disassembly and assembly device can be used, this embodiment is designed as follows:

[0031] As attached Figure 2 and attached Figure 4As shown, in this embodiment, a clutch assembly 6 is provided between the sleeve 5 and the rotating shaft 2; preferably, the clutch assembly 6 comprises a first toothed disc 6.1, a second toothed disc 6.2, a connecting sleeve 6.3 and a spring 6.4, the first toothed disc 6.1 and the second toothed disc 6.2 can be meshed for transmission, wherein the first toothed disc 6.1 is welded to the bottom end of the rotating shaft 2, the bottom surface of the second toothed disc 6.2 is provided with a non-cylindrical plug 6.2.1, preferably a square head, and the corresponding sleeve 5 is provided with a square hole 5.1, the second toothed disc 6.2 is provided in the connecting sleeve 6.3, and its plug 6.2.1 passes through the connecting sleeve 6.3 and is plugged into the sleeve 5, the first toothed disc 6.1 is provided in the connecting sleeve 6.3 relative to the second toothed disc 6.2 and is limited by a retaining ring 6.3.1, and the spring 6.4 is provided between the first toothed disc 6.1 and the second toothed disc 6.2. This design ensures that the shaft and the sleeve are separated under normal conditions, and the sleeve can be rotated freely to facilitate adjustment of the adjustment direction so that it is aligned with the nut. When in use, it is only necessary to press down the fixed plate to engage the first gear plate and the second gear plate to achieve the connection between the shaft and the sleeve and transmit torque, thereby solving the problem of manual tightening of the nut due to mismatch in the direction of the sleeve and the nut.

[0032] Preferably, as attached Figure 4 As shown, the middle parts of the first toothed disc 6.1 and the second toothed disc 6.2 are both provided with an annular groove, and the spring 6.4 is arranged in the annular groove. This design is conducive to the positioning of the spring and prevents the problem of spring misalignment during use of the device.

[0033] Preferably, the square head is provided with an elastic top bead (not shown in the figure), and the sleeve 5 is provided with a positioning hole (not shown in the figure) passing through the square hole 5.1. This design can improve the plug-in stability of the sleeve and the plug, and can effectively prevent the sleeve from falling out of the plug.

[0034] Embodiment 2

[0035] Based on the first embodiment, this embodiment specifically designs the fixed disk, as shown in the attached Figure 2 As shown, the fixed plate 1 includes a top plate 1.1, a bottom plate 1.2 and a plurality of support components 1.3 disposed between the top plate and the bottom plate, the support components 1.3 include a support sleeve 1.3.1 and a bolt 1.3.2, the support sleeve 1.3.1 is disposed between the top plate 1.1 and the bottom plate 1.2, and the bolt 1.3.2 fastens the bottom plate 1.2, the support sleeve 1.3.1 and the top plate 1.1. The driving gear 4 and the driven gear 3 are both assembled on the rotating shaft 2, and the rotating shaft 2 is rotatably connected to the bottom plate 1.2 and the top plate 1.1 respectively through bearings.

[0036] Further, as attached Figure 3As shown, the top plate 1.1 and the bottom plate 1.2 are provided with a plurality of bull's eye wheels 7 on the upper and lower surfaces relative to the driving gear 4 and each of the driven gears 3, and the bull's eye wheels 7 are in contact with the driving gear 4 and the driven gear 3. At present, in order to reduce the friction of the gears during transmission, it is necessary to set a gap between the upper and lower surfaces of the gears. During the transmission process, the gears will be displaced because their upper and lower surfaces have no support, which makes them contact with the bottom plate, resulting in a problem of large friction. Therefore, the bull's eye wheels designed in this embodiment can support the positions of the driving gear and the driven gear to ensure their stable positions, and there is rotational friction between the bull's eye wheels and the gears, and the friction is very small, so the device has low resistance during transmission and is relatively smooth.

[0037] Preferably, each of the driven gear 3 and the driving gear 4 is evenly provided with at least three bull's eye wheels 7 around its rotating shaft 2, and the bull's eye wheels 7 are embedded on the top plate 1.1 and the bottom plate 1.2.

[0038] Application example: The flange bolt synchronous disassembly and assembly device designed in this application can be directly used for the rapid disassembly and assembly of the concrete impermeability test mold. The test mold of the impermeability tester is installed on the instrument through 6 bolts. A synchronous disassembly and assembly device with 6 rotating shafts can be designed to meet its use requirements. It is worth noting that the height of the rotating shaft must be higher than the height of the test mold. Other similar flange bolts can also be applied to this device.

[0039] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
