Technical Field

[0001] This utility model relates to the field of high-speed rail application technology, and in particular to a lifting tool for high-speed rail castings. Background Technology

[0002] Casting lifting fixtures are specialized tools and equipment used for lifting, handling, and installing castings during or after the casting production process. There are many types of casting lifting fixtures, and different fixtures are suitable for different types of castings, production scenarios, and process requirements. Reasonable selection and use of casting lifting fixtures can not only improve production efficiency but also ensure the quality of castings and reduce safety risks in the production process.

[0003] Existing high-speed rail castings require lifting fixtures during processing. These fixtures are typically connected by wire ropes or chains, which can scratch and damage the outer surface of the castings during clamping or placement. Furthermore, the lifting fixtures cannot be effectively and flexibly adjusted when lifting castings of different sizes, thus reducing the efficiency of the lifting process. Therefore, this utility model proposes a lifting fixture for high-speed rail castings. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lifting tool for high-speed rail castings. By setting movable and adjustable clamping frames on the clamping frame of the lifting tool, it can adjust the clamping of different castings, thereby improving the flexibility and efficiency of the lifting tool in operation. At the same time, a clamping angle adjustment structure is set at the clamping connection of the lifting tool to further improve the convenience of the lifting tool in operation.

[0005] To solve the above-mentioned technical problems, the present invention provides a lifting fixture for high-speed rail castings, including an external rod, a rotating mechanism fixedly connected to the end face of the external rod, a protective shell fixedly connected to the bottom of the rotating mechanism, a clamping mechanism detachably installed inside the protective shell, and an adjustable clamping part provided at the bottom of the clamping mechanism.

[0006] The present invention is further configured such that: the rotating mechanism includes a fixed plate, a rotating motor is bolted to the top of the fixed plate near the outer wall, the drive shaft of the rotating motor passes through the fixed plate and a drive gear is sleeved on its end face, and a rotating disk is meshed with the outer wall of the drive gear.

[0007] By using the above technical solution, the rotary motor is started, and its drive shaft drives the drive gear on the end face to rotate, thereby driving the meshing rotating disk to rotate stably on the fixed plate.

[0008] The present invention is further configured such that: the rotating disk is rotatably connected to the center of the fixed plate via a rotating shaft located at its center, and the top of the rotating disk and the bottom of the fixed plate are smoothly fitted together.

[0011] By using the above technical solution, the clamping motor is started, and its drive shaft drives the worm gear on the end face to rotate, thereby driving the meshing worm wheel, which in turn causes the connected drive column to rotate relative to it, causing the clamping frame on the end face to rotate, and finally achieving the clamping and fixing of the high-speed rail casting.

[0012] The present invention is further configured such that both clamping frames are U-shaped, and the tops of both clamping frames are threadedly connected to an adjustment hole opened near the end face of the outer wall of the drive column by a through-bolt.

[0013] The above technical solution facilitates the adjustment of the angle of the clamping frame on the drive column, thereby making it convenient to clamp and fix different castings at appropriate angles.

[0014] The present invention is further configured such that: the clamping part includes a slide rod, and a slide frame is symmetrically slidably connected to the outer wall of the slide rod near the end face, and a protective clamping block is fixedly connected to one side of the slide frame.

[0015] The above technical solution facilitates the use of a slide to slide on a slide bar, thereby adjusting and fixing the position of the protective clamp.

[0016] The present invention is further configured such that: a slider is fixedly connected to the inner side wall of the slide, and is slidably connected to the slide groove opened in the side wall of the slide rod through the slider; a locking bolt is threaded through the other side of the slide, and the end face of the locking bolt abuts against the side wall of the slide rod.

[0017] The above technical solution facilitates the sliding of the carriage on the slide rod, thereby adjusting the clamping position and making it convenient to clamp different castings in the appropriate position. Furthermore, the locking bolts can be used to lock and fix the adjusted carriage in place.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] like Figures 1-3As shown, a lifting fixture for high-speed rail castings includes an external rod 1 and a rotating mechanism 2 fixedly connected to the end face of the external rod 1. The rotating mechanism 2 includes a fixed plate 21. A rotary motor 22 is bolted to the top of the fixed plate 21 near the outer wall. The drive shaft of the rotary motor 22 passes through the fixed plate 21, and a drive gear 23 is sleeved on its end face. A rotating disk 24 is meshed with the outer wall of the drive gear 23. When the rotary motor 22 is started, its drive shaft drives the drive gear 23 on the end face to rotate, thereby driving the meshed rotating disk 24 to rotate stably on the fixed plate 21. The rotating disk 24 is rotatably connected to the center of the fixed plate 21 through a rotating shaft 241 set at its center. The top of the rotating disk 24 and the bottom of the fixed plate 21 are smoothly fitted together, which facilitates the stable rotation of the rotating disk 24 on the fixed plate 21 through the rotating shaft 241, thereby facilitating angle adjustment during clamping.

[0028] like Figure 2 and Figure 3 As shown, a protective shell 3 is fixedly connected to the bottom of the rotating mechanism 2. A clamping mechanism 4 is detachably installed inside the protective shell 3. The clamping mechanism 4 includes a mounting plate 41 bolted to the bottom of the protective shell 3. A clamping motor 42 is bolted to the center of the bottom of the mounting plate 41. The end face of the drive shaft of the clamping motor 42 passes through the mounting plate 41 and is fixedly connected to a worm gear 43. Worm wheels 44 are symmetrically meshed on the outer wall of the worm gear 43. Drive pins 45 are sleeved on the inner walls of the two worm wheels 44. Both drive pins 45 pass through the protective shell 3, and clamping frames 46 are sleeved on their end faces. The clamping motor 42 is then started. Its drive shaft drives the worm gear 43 on the end face to rotate, thereby driving the meshing worm wheel 44, which in turn causes the connected drive column 45 to rotate relative to it, causing the clamping frame 46 on the end face to rotate, and finally achieving the clamping and fixing of the high-speed rail casting. Both clamping frames 46 are U-shaped. The top of both clamping frames 46 are threaded to the adjustment hole 451 opened near the end face of the outer wall of the drive column 45 by a through-hole fixing bolt, which facilitates the adjustment of the angle of the clamping frame 46 on the drive column 45, thereby facilitating the appropriate angle clamping and fixing of different castings.

[0029] like Figure 4As shown, the bottom of the clamping mechanism 4 is provided with an adjustable clamping part 5. The clamping part 5 includes a slide rod 51. A slide frame 52 is symmetrically slidably connected to the outer wall of the slide rod 51 near the end face. A slider 521 is fixedly connected to the inner side wall of the slide frame 52 and is slidably connected to the slide groove 511 opened in the side wall of the slide rod 51 through the slider 521. A locking bolt 522 is threadedly connected to the other side of the slide frame 52, and the end face of the locking bolt 522 abuts against the side wall of the slide rod 51, so as to facilitate the sliding of the slide frame 52 on the slide rod 51 and adjust the clamping position. This makes it convenient to clamp different castings in the appropriate position. The locking bolt 522 can lock and fix the position of the adjusted slide frame 52. A protective clamping block 53 is fixedly connected to one side of the slide frame 52, so as to facilitate the sliding of the slide frame 52 on the slide rod 51 and adjust and fix the position of the protective clamping block 53.

[0030] In use, the present invention first starts the rotary motor 22, whose drive shaft drives the drive gear 23 on the end face to rotate, thereby driving the meshing rotating disk 24 to rotate stably on the fixed plate 21. Then, the slide 52 slides on the slide rod 51, and the locking bolt 522 can lock and fix the adjusted slide 52 in position. Next, the clamping motor 42 is started, whose drive shaft drives the worm gear 43 on the end face to rotate, thereby driving the meshing worm wheel 44, which in turn causes the connected drive column 45 to rotate relative to each other, causing the clamping frame 46 on the end face to rotate, and finally driving the protective clamping block 53 on the slide 52 to clamp and fix the high-speed rail casting.
