Description

Technical Field

[0001] The utility model relates to the field of water mill devices, in particular to a concrete water mill re-grinding and pressing device. Background Art

[0002] Concrete is a widely used building material, made from a mixture of cement, water, sand (fine aggregate) and gravel (coarse aggregate). This material is widely used in engineering structures such as buildings, roads, bridges, dams, etc. due to its high strength, good durability and relatively low cost.

[0003] In order to improve the flatness of the ground, the concrete is generally polished. During the polishing process, the machine body drives the rotating column to rotate, and the rotating column drives the mounting plate to rotate, so that multiple grinding blocks installed on the mounting plate rotate at high speed to achieve the polishing of the ground. Among them, a plurality of plug holes are opened on the mounting plate, and the plug rods are inserted into the plug holes. One end of the plug rod is fixedly connected with a grinding block, and the other end of the plug rod is threaded with a nut. By tightening the nut, the grinding block is installed on the mounting plate. Then, during the water grinding work, the grinding block is in compression contact with the ground, and the grinding block drives the plug rod and the nut to rotate at high speed, so the force at the connection between the plug rod and the nut is relatively large, so that the plug rod and the nut are prone to loosening during long-term use of the device.

[0004] Therefore, it is necessary to provide a new concrete water mill re-grinding and fine pressing device to solve the above technical problems. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] Please refer to Figure 1-Figure 7 ,in, Figure 1 A schematic diagram of the structure of the concrete water mill re-grinding and pressing device provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of a side view of the structure shown; Figure 3 for Figure 1 A schematic diagram of a local structure of the structure shown; Figure 4 for Figure 2 A schematic diagram of the structure of the pressing plate, the cross block and the elastic telescopic member as viewed from bottom; Figure 5 for Figure 1 The schematic diagram of the structure of the grinding block, the insert rod, the nut and the anti-slip pad shown; Figure 6 for Figure 1 The structural schematic diagram of the cross block and the elastic expansion member shown; Figure 7 for Figure 1 The structural diagram of the installation disk is shown.

[0026] In the specific implementation process, Figure 1-Figure 7As shown, it includes a body 1, a rotating column 2 is installed at one end of the body 1, and a mounting plate 3 is detachably connected to the bottom of the rotating column 2, which can be fixed with bolts or screws to achieve detachability. A motor is provided inside the body 1 to drive the rotating column 2 to rotate, so as to drive the mounting plate to rotate. A plurality of sockets 4 are provided on the mounting plate 3, and a plug rod 6 is movably inserted in the socket 4. The plug rod 6 is threadedly connected to the socket 4 to achieve fixation. An anti-slip gasket 18 is sleeved on the plug rod 6, and the anti-slip gasket 18 is made of rubber. A grinding block 5 is fixedly installed at one end of the plug rod 6, and a cross groove 9 is provided at the other end of the plug rod 6, and a nut 7 for axially limiting the plug rod 6 is threadedly connected to the end of the plug rod 6 with the cross groove 9. A lifting device is installed on the body 1, and a pressing plate 8 is installed on the lifting end of the lifting device. A plurality of cross blocks 10 are fixedly connected to the bottom of the pressing plate 8, and the plurality of cross blocks 10 are respectively arranged corresponding to the plurality of cross grooves 9, and the size of the cross block 10 is adapted to the size of the cross groove 9.

[0027] The lifting device includes a first bracket 14, a threaded rod 15 and a guide member. One end of the first bracket 14 is fixedly connected to the pressing plate 8, and the threaded rod 15 is rotatably connected to the body 1. The threaded rod 15 is threadedly connected to the first bracket 14, and the guide member is installed at the end of the pressing plate 8 away from the first bracket 14. The guide member includes a second bracket 16 and a guide rod 17. One end of the second bracket 16 is fixedly connected to the end of the pressing plate 8 away from the first bracket 14. The bottom end of the guide rod 17 is fixedly installed on the top of the body 1, and the guide rod 17 is movably inserted into the through hole opened in the second bracket 16. The threaded rod 15 is rotated. Since one end of the pressing plate 8 is fixedly connected to the second bracket 16, the second bracket 16 is limited by the guide rod 17. Therefore, when the threaded rod 15 rotates, the pressing plate 8 moves downward.

[0028] The bottom of the pressing plate 8 is located at the periphery of multiple cross blocks 10, and elastic retractable parts are provided. When the cross block 10 enters the cross groove 9, the elastic retractable part is sleeved on the outside of the insertion rod 6, and the end of the elastic retractable part presses the nut 7. The elastic retractable part includes a fixing ring 11, a pressing ring 13 and multiple springs 12. The top of the fixing ring 11 is fixedly connected to the bottom of the pressing plate 8, and the bottom of the fixing ring 11 is movably arranged in an annular groove opened at the top of the pressing ring 13. The two ends of the multiple springs 12 are respectively fixedly connected to the bottom end of the fixing ring 11 and the bottom wall of the groove of the pressing ring 13. When the cross block 10 is moved into the cross groove 9, the spring 12 is in a compressed state. The pressing ring 13 is pressed on the nut 7 by the spring 12, so that the insertion rod 6 is not easy to rotate. The cross block 10 plays a role in limiting the horizontal direction of the insertion rod 6, so that the insertion rod 6 and the nut 7 are not easy to loosen during use.

[0029] A housing 19 is fixedly installed on one side of the bottom of the machine body 1. A motor is arranged in the housing 19. A fine grinding disc 20 is fixedly installed on the output end of the motor. The fine grinding disc 20 is driven to rotate by the motor, so as to grind the ground again.

[0030] The working principle provided by the utility model is as follows: when using the device, the anti-slip gasket 18 is sleeved on the insertion rod 6, the insertion rod 6 is inserted into the insertion hole 4, and the grinding block 5 is installed on the bottom of the mounting plate 3 through the nut 7. Then, the threaded rod 15 is rotated. Since one end of the pressing plate 8 is fixedly connected to the second bracket 16, the second bracket 16 is limited by the guide rod 17, so when the threaded rod 15 rotates, the pressing plate 8 moves down. When the pressing ring 13 contacts the nut 7, the threaded rod 15 continues to be rotated, so that the pressing plate 8 continues to move down, and the cross block 10 moves into the cross groove 9. When the cross block 10 completes the movement into the cross groove 9, the spring 12 is in a compressed state, making the insertion rod 6 difficult to rotate. The pressing ring 13 presses the nut 7 through the spring 12, and the cross block 10 plays a role in limiting the horizontal direction of the insertion rod 6, so that the insertion rod 6 and the nut 7 are not easy to loosen during use.
