The sand returning trough is connected to the primary dust collector, and the primary dust collector is connected to the secondary dust collector and the sand blasting machine.

[0003] Although the rotating platform can realize the free rotation of the workpiece in the above-mentioned workpiece rotating automatic sand returning dry sand blasting room, the workpiece rotating automatic sand returning dry sand blasting room still has the following disadvantages: the specific structure of the rotating platform is unknown. Since the workpieces such as bridge inclined cables or anchors have the disadvantages of heavy weight and large volume, in order to ensure that the workpieces can be stably supported, the rotating platform needs to have a large bearing area. At the same time, in order to ensure that the rotating platform can be fully and stably supported, a supporting surface as large as the bearing area needs to be set. In order to reduce friction, the friction coefficient of the supporting surface needs to be reduced. However, reducing the friction coefficient of the supporting surface with a larger area increases the difficulty of production. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0025] Embodiment 1:

[0026] like Figures 1 to 4 As shown, the present embodiment discloses a bridge cable-stayed anchor sandblasting and zinc-spraying rotating platform, comprising: a bearing pedestal 1, a rotating cylinder 2, an articulated base 3, a supporting device 4 and a bottom bracket 5; the top surface of the bearing pedestal 1 is a bearing surface, and the bearing surface is used to place the bridge cable or anchor, and a rotating cylinder 2 is installed at the bottom of the bearing pedestal 1, and the rotating cylinder 2 is rotatably installed on the articulated base 3, and the articulated base 3 supports the rotating cylinder 2, and a supporting device 4 is installed on the articulated base 3, and there are at least three supporting devices 4, and a rotatable supporting roller is arranged in the supporting device 4, and the supporting roller supports the ground of the bearing pedestal 1, and the axis center lines of all the supporting rollers are located in the radial direction of the rotating cylinder 2; the articulated base 3 comprises: a guide cylinder 31, a ball bearing 32 and a seat body 33, and the guide cylinder 31 and the supporting device 4 are installed on the seat body 33, and the supporting device 4 surrounds the outside of the guide cylinder 31, and the guide cylinder 31 is for the rotating cylinder 2 to extend into, and a ball bearing 32 is installed between the rotating cylinder 2 and the inner wall of the guide cylinder 31.

[0027] The support device 4 includes: a support seat 411 and a second rotating shaft 412. The support seat 411 is fixed on the seat body 33, and the support seat 411 is penetrated by the second rotating shaft 412, and the second rotating shaft 412 penetrates the rotatable support roller. The support seat 411 is fixed on the seat body 33, and the second rotating shaft 412 realizes the rolling installation of the support roller.

[0028] A limit mechanism 6 is installed at the installation position of the rotating cylinder 2 and the guide cylinder 31, and the limit mechanism 6 is used to limit the movement of the rotating cylinder 2 relative to the guide cylinder 31 in the direction of the axis of the guide cylinder 31. After the rotating cylinder 2 and the bearing platform are installed on the seat body 33 of the hinged base 3, it is necessary to limit the movement of the bearing platform and the rotating cylinder 2 on the axis of the rotating cylinder 2 to avoid the rotating cylinder 2 and the bearing platform from jumping.

[0029] The limiting mechanism 6 includes: a cover ring 61, an anti-slip ring 62, an anti-slip screw 63 and an anti-slip nut 64. The cover ring 61 installs one end of the anti-slip ring 62 on the rotating cylinder 2. The anti-slip ring 62 can rotate relative to the rotating cylinder 2. The anti-slip ring 62 and the guide cylinder 31 are passed through by the anti-slip screw 63. The anti-slip ring 62 surrounds the outside of the guide cylinder 31. The two ends of the anti-slip screw 63 are threadedly connected with anti-slip nuts 64, and the two anti-slip nuts 64 are located on both sides of the anti-slip ring 62. The cover ring 61 is to install the anti-slip ring 62 on the rotating cylinder 2, and the anti-slip ring 62 can rotate relative to the bearing platform and the rotating cylinder 2. After the anti-slip ring 62 and the guide cylinder 31 are passed through by the anti-slip screw 63, the anti-slip ring 62 and the guide cylinder 31 are restricted from being separated, and then the rotating cylinder 2 is restricted from being separated from the guide cylinder 31. After being installed, the guide cylinder 31 and the anti-slip ring 62 will be stabilized on the seat body 33 together and will not rotate, but the bearing platform and the rotating cylinder 2 will rotate together.

[0030] A support cylinder 7 is installed at the bottom of the guide cylinder 31, and the support cylinder 7 supports the ball bearing 32. Since the bottom of the guide cylinder 31 needs to be passed through by the anti-slip screw 63, the support cylinder 7 is provided to support the ball bearing 32 and the rotating cylinder 2 to prevent the anti-slip screw 63 from affecting the rotation of the rotating cylinder 2.

[0031] The inner wall of the guide cylinder 31 protrudes to form a positioning ring 310, which positions the support cylinder 7. The support cylinder 7 cannot rotate relative to the positioning ring 310, and the height of the positioning ring 310 is less than the height of the support cylinder 7. Since the support cylinder 7 needs to be passed through by the anti-slip screw 63, a positioning ring 310 is provided to position the position of the support cylinder 7, and to position the relative position of the support cylinder 7 and the guide cylinder 31, so as to ensure that the anti-slip screw 63 passes through the support cylinder 7 and the guide cylinder 31 at one time. The height of the support cylinder 7 is matched with the height of the rotating cylinder 2, so as to ensure that the support cylinder 7 fully supports the rotating cylinder 2, and the top surface of the support cylinder 7 is the support surface for the rotating cylinder 2, ensuring the smoothness of the top surface of the support cylinder 7 to reduce the friction coefficient. The support surface is on the rotating cylinder 2. In order to avoid contact between the positioning ring 310 and the rotating cylinder 2, the height of the support cylinder 7 is set to be higher than the height of the positioning ring 310.

[0032] Embodiment 2:

[0033] The difference between this embodiment and the first embodiment is that the structure of the supporting device 4 is different, and the other structures are the same.

[0034] like Figures 5 to 7As shown, the supporting device 4 includes: a mounting seat 421, a mounting screw 422, an upper nut 423, a lower nut 424 and a first rotating shaft 425. The mounting seat 421 is penetrated by two mounting screws 422. The mounting seat 421 is threaded with an upper nut 423 and a lower nut 424. The upper nut 423 and the lower nut 424 cooperate to clamp the mounting seat 421. The mounting screw 422 is installed on the seat body 33. The mounting seat 421 is penetrated by a first rotating shaft 425. The first rotating shaft 425 passes through a rotatable supporting roller.

[0035] In this embodiment, the height of the mounting seat 421 is adjusted by adjusting the positions of the upper nut 423 and the lower nut 424 , so as to adjust the supporting platform 1 to a specified height position.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
