DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] A casting maintenance hoisting device comprises a bracket 1, a crossbeam 2 is arranged on the top of the bracket 1, and lifting frames 21 are arranged at the bottom of both ends of the crossbeam 2. The lifting frames 21 are located in the inner cavity of the bracket 1, and the lifting frames 21 can be driven to move up and down by a cylinder 11. A clamping device 3 is arranged at the bottom of the crossbeam 2, and the clamping device 3 comprises a mounting frame 31, a fixing plate 32 is arranged at the bottom of the mounting frame 31, a servo motor 33 is arranged inside the mounting frame 31, and a driving gear 34 is arranged at the output end of the servo motor 33. A first linkage plate 35 and a second linkage plate 36 are movably connected to the two sides of the bottom of the fixing plate 32 respectively, and one end of the first linkage plate 35 and the second linkage plate 36 are fixedly connected to a clamping plate 37, and the corresponding surfaces of the two clamping plates 37 are opened with movable grooves 371, and a number of positioning members 38 are arranged on the top of the inner cavity of the movable groove 371, and a supporting plate 372 is movably connected to the inner wall of the movable groove 371.

[0024] In this embodiment, please refer to Figure 4-5 The positioning member 38 includes a sleeve 381, the inner cavity of the sleeve 381 is provided with a spring 382, ​​the bottom of the spring 382 is fixedly connected with a positioning ball 383, and the top of the support plate 372 is provided with an embedding hole 373 compatible with the positioning ball 383. In this embodiment, when the support plate 372 moves, its top will push the positioning ball 383 to move upward, and squeeze the spring 382 to cause it to deform. When the embedding hole 373 moves to just below the positioning ball 383, the spring 382 loses pressure and rebounds, pushing the positioning ball 383 into the inner cavity of the embedding hole 373, thereby keeping the position of the support plate 372 stable.

[0025] In this embodiment, please refer to Figure 3The corresponding surfaces of the first linkage plate 35 and the second linkage plate 36 are both provided with gear grooves, and the gear grooves are meshed with the outer edge of the driving gear 34. In this embodiment, when the driving gear 34 rotates, it will drive the first linkage plate 35 and the second linkage plate 36 to move. According to the rotation direction of the driving gear 34, the first linkage plate 35 and the second linkage plate 36 can be driven to move towards each other or away from each other.

[0026] In this embodiment, please refer to Figure 3 , support rods 321 are provided on both sides of the fixed plate 32, a pulley 322 is provided on one side of the support rod 321, a sliding groove 351 is opened on one side of the first linkage plate 35 and the second linkage plate 36, and the outer side of the pulley 322 is adapted to the inner wall of the sliding groove 351. In this embodiment, when the first linkage plate 35 and the second linkage plate 36 move, the pulley 322 will rotate in the inner cavity of the sliding groove 351, reducing friction and making the first linkage plate 35 and the second linkage plate 36 move more smoothly.

[0027] In this embodiment, please refer to Figure 4 A number of suction cups 374 are provided on the corresponding surfaces of the two clamps 37. In this embodiment, when the clamps 37 clamp the casting, the suction cups 374 are squeezed and adhered to the surface of the casting, and generate adsorption force, which protects the casting from being squeezed and makes the casting clamped more stably.

[0028] In this embodiment, please refer to Figure 5 The bottom inner cavity of the sleeve 381 is provided with an anti-slip groove 384, and the outer side of the positioning ball 383 is provided with an anti-slip ring 385, and the outer side of the anti-slip ring 385 is transitionally matched with the inner wall of the anti-slip groove 384. In this embodiment, when the positioning ball 383 moves up and down in the inner cavity of the sleeve 381, the anti-slip ring 385 will move up and down along the inner wall of the anti-slip groove 384. The transitional fit between the anti-slip groove 384 and the anti-slip ring 385 can prevent the positioning ball 383 from escaping from the inner cavity of the sleeve 381.

[0029] Working principle of this utility model:

[0030] Step 1, in the utility model, the lifting frame 21 is driven downward by the cylinder 11, so that the crossbeam 2 drives the clamping device 3 to move downward, and after the casting is placed between the two clamping plates 37, the servo motor 33 is used to give power to control the driving gear 34 to rotate. Since the outer edge of the driving gear 34 is meshed with the outer edges of the first linkage plate 35 and the second linkage plate 36, when the driving gear 34 rotates, it will drive the first linkage plate 35 and the second linkage plate 36 to move in different directions, so that the first linkage plate 35 and the second linkage plate 36 To generate opposite movement or opposite movement, when the first linkage plate 35 and the clamping plate 37 generate opposite movement, the clamping plates 37 are driven respectively, so that the two clamping plates 37 generate opposite movement, and the distance between them gradually decreases, so that the casting is clamped by the clamping plates 37, and the crossbeam 2 is driven upward by the cylinder 11 to lift the casting, so as to facilitate the inspection of the casting, and by controlling the rotation direction of the driving gear 34, the distance between the two clamping plates 37 can be increased, the clamping of the casting can be stopped, and a larger casting can be clamped;

[0031] Step 2. In the utility model, after the clamp is clamped by the clamp 37, the support plate 372 can be moved along the inner wall of the movable groove 371. When the support plate 372 moves, the positioning ball 383, due to its spherical shape, receives thrust and is squeezed out of the inner cavity of the embedding hole 373, and squeezes the spring 382 to cause it to deform. When the overall length of the casting is shorter than the clamp 37, the support plate 372 can be moved to the bottom of the casting, and the positioning ball 383 there can be made to enter the inner cavity of the embedding hole 373. After the position of the support plate 372 remains stable, the casting can be prevented from falling. When the overall length of the casting is longer than the clamp 37, the support plate 372 can be clamped on the narrower sides of the casting, which can also prevent the casting from falling to a certain extent.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. The utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. The utility model may have various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
