[0031] Example 1

[0032] Reference Figures 1-3 This is the first embodiment of the present utility model, which provides a ring forging lifting device. This ring forging lifting device includes a support unit 100, the support unit 100 includes a support platform 101, a circular hole 102 is opened below the support platform 101, a gear chamber cover 103 is fixedly installed below the support platform 101, and a "Y"-shaped moving groove 104 is opened on the support platform 101.

[0033] The limiting unit 200 includes a driven gear disk 201 placed in the space formed by the gear chamber cover 103 and the circular hole 102. A spiral threaded track 202 is provided above the driven gear disk 201, and three movable claws 203 are slidably installed on the "Y"-shaped moving groove 104.

[0034] The drive unit 300 includes a drive gear disk 301 that meshes with the driven gear disk 201. The drive gear disk 301 is placed inside the gear chamber cover 103, and an operating disk 302 is fixedly installed below the drive gear disk 301.

[0035] The movable chuck is installed on a "Y"-shaped moving slot. The bottom of the movable chuck contacts the threaded rail. The rotation of the threaded rail drives the movement of the movable chuck. Under the restriction of the "Y"-shaped moving slot, the movable chuck can only move along the slot opening. The movable chuck can form circles of different sizes when it moves to different positions, thereby limiting the ring forgings of different sizes on the support platform. The circular hole provides space for the placement of the driven gear disk. The driven gear and the drive gear mesh with each other and are placed inside the gear chamber cover. The control panel and the drive gear disk are a whole. When the control panel is rotated, the drive gear will rotate with the control panel. The driven gear and the drive gear mesh with each other, and the driven gear will rotate with the rotation of the drive gear. Because the driven gear is in the center of the support platform, it is impossible to rotate the driven gear directly. Therefore, the drive gear is installed as a transmission mechanism to facilitate the operation of the device.

[0036] Example 2

[0037] Reference Figure 4 , Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: support columns 105 are provided on both sides below the support platform 101, and a certain space is left between the left and right ends of the support platform 101 and the support columns 105; lifting rings 106 are fixedly installed at the four corners of the upper surface of the support platform 101; the gear chamber cover 103 is designed in the shape of an "8" according to the shape after the driven gear disk 201 and the driving gear disk 301 mesh; the space formed by the circular hole 102 and the gear chamber cover 103 is the driven gear chamber 107, in which the driven gear disk 201 is placed; the space formed by the bottom surface of the support platform 101 and the gear chamber cover 103 is the driving gear chamber 108, in which the driving gear disk 301 is placed; a rotating shaft 109 is provided at the center of the bottom surface of the driven gear chamber 107; and the driving gear chamber 108... A through hole 110 is provided at the center of the bottom surface of the 8. A limit post 111 is provided around the through hole 110. A fixing ring 112 is provided around the gear chamber cover 103. A threaded hole 113 corresponding to the fixing ring 112 is provided on the support platform 101. A screw 114 is provided in the threaded hole 113. A moving guide rail 115 is provided at the opening of the "Y"-shaped moving groove 104. An installation groove 116 is provided behind the "Y"-shaped moving groove 104. A rectangular limit block 117 is placed inside the installation groove 116. The "Y"-shaped moving groove 104 includes a first moving groove 104a, a second moving groove 104b and a third moving groove 104c. The number "1" 118a is engraved next to the first moving groove 104a, the number "2" 118b is engraved next to the second moving groove 104b, and the number "3" 118c is engraved next to the third moving groove 104c.

[0038] The support column elevates the support platform to facilitate the use of a forklift lifting device and provides space for the installation of the annular chuck below. The eye bolts are primarily used by lifting equipment to lift the device. The circular holes on the retaining ring around the gear chamber cover are aligned with and the same size as the threaded holes on the support platform. Screws pass through the retaining ring and threaded holes to secure the gear chamber cover to the underside of the support platform. The gear chamber cover limits the movement of the driven and driving gear discs. The rotating shaft supports the rotation of the driven gear disc, and the through hole facilitates the rotation of the control panel. The limiting column limits the movement of the driving gear disc. The limiting function prevents the bottom of the drive gear disk from contacting the gear chamber cover. The moving guide rail limits the movement of the movable claw. Because of the presence of the moving guide rail, the movable claw cannot be directly placed into the "Y"-shaped moving slot during installation. Therefore, an installation slot needs to be opened behind the "Y"-shaped moving slot. After the movable claw is installed, a rectangular limiting block is placed inside the installation slot to prevent the movable claw from moving beyond the distance and being unable to return. The "Y"-shaped moving slot is divided into three moving slots, with an included angle of 120° between each pair of moving slots. Numbers are engraved next to the moving slots to facilitate the identification of the movable claw installation.

[0039] The remaining structure is the same as that in Example 1.

[0040] Example 3

[0041] Reference Figure 5 , Figure 6 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: a circular rotating groove 204 is provided below the driven gear disk 201; a rotating shaft 109 is provided on the gear chamber cover 103 at a position corresponding to the rotating groove 204; a bearing 205 is fixedly installed in the space formed by the rotating shaft 109 and the rotating groove 204; the outer ring of the bearing 205 is fixedly installed on the rotating groove 204; the inner ring of the bearing 205 is fixedly installed on the rotating shaft 109; and guide rail grooves 2 are provided on both sides of the middle of the movable pawl 203. 06. The movable guide rail 115 cooperates with the guide rail groove 206. The bottom surface of the movable claw 203 is provided with a groove 207 corresponding to the threaded rail 202. A step 208 is provided above the movable claw 203. A chamfer 209 is provided in front of the bottom step of the step 208. The step 208 is engraved with the number 118 on its side. The first claw 203a is engraved with the number "1" 118a on its side. The second claw 203b is engraved with the number "2" 118b on its side. The third claw 203c is engraved with the number "3" 118c on its side.

[0042] The rotating shaft and rotating groove provide space for the bearing. The bearing reduces the coefficient of friction through rolling friction and is movably mounted on the rotating shaft. The driven gear can only rotate around the rotating shaft. The recessed part of the groove matches the cut shape of the threaded protrusion, allowing the movable jaw to slide on the threaded track. The movement of the movable jaw can limit the movement of ring forgings of different sizes. Steps of different heights correspond to ring forgings of different sizes. The grooves correspond to different positions on the threaded track, and the groove shapes are also different. To prevent confusion during installation, each jaw and each groove of the "Y"-shaped moving groove is numbered, and the numbers are also displayed on the side of the jaw. The groove is engraved with numbers. During installation, install according to the corresponding numbers. The guide rail groove and the movable guide rail have the same shape. During installation, push the movable groove into the movable guide rail, rotate the control panel, and observe the position of the end of the threaded rail. When the end of the threaded rail appears in the first movable groove, back it up a little and push the first chuck to abut against the threaded rail. Rotate the control panel to make the end of the threaded rail enter the groove at the front end of the first chuck groove. Then, install the second and third chucks in the same way. After the movable chuck is installed, place the rectangular limit block in the installation groove. The chamfer is to ensure that the movable chuck can be accurately zeroed after installation.

[0043] The remaining structure is the same as that in Example 2.

[0044] Example 4

[0045] Reference Figure 7 This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that: an annular column 303 is provided below the drive gear disk 301, and a connecting hole 304 is provided around the part of the annular column 303 that passes through the through hole 110. The control disk 302 is composed of a connecting rod 305 and a control lever 306. One end of the connecting rod 305 is inserted into the connecting hole 304, and the other end of the connecting rod 305 is fixedly installed on the control lever 306.

[0046] In order to reduce the overall weight of the drive gear disk so that it can rotate, the annular column passes through the through hole to provide a position for the control panel to be installed. During installation, one end of the connecting rod is inserted into the round hole on the annular column, and the other end of the connecting rod is welded to the control lever to form a fixed structure. Both the annular chuck and the control lever are rigid structures. After one end of the connecting rod is fixedly installed to the control lever, the other end inserted into the round hole cannot move, thus forming a fixed structure.

[0047] The remaining structure is the same as that in Example 3.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
