Description

Technical Field

[0001] The invention relates to the field of matching tools for diamond presses, in particular to an internal support balancing hanger for a diamond press steel ring. Background Art

[0002] The six-sided top press is a key equipment for the synthesis of superhard materials. It generates a pressure of up to several GPa through six working cylinders and is used to synthesize materials such as artificial diamonds under high temperature conditions. The top hammer of the six-sided top press is one of the core components of the six-sided top press. It is directly involved in the formation of the synthesis cavity and the maintenance of the high-pressure environment. It is an important factor in determining the quality of diamond synthesis. The steel ring accessory of the top hammer is an overall irregular heavy object, but its fixing screws are evenly distributed around a regular circle. When replacing the hammer head of the top hammer, the steel ring needs to be hoisted as a whole. The current hoisting method is to use a simple hook to pass through one of the screw holes to directly lift it. On the one hand, this method is easy to slip due to its unstable center of gravity. On the other hand, when hoisting to the designated position, it is necessary to manually adjust its landing posture. The operation is extremely inconvenient and the safety risk is relatively high.

[0015] For the structure of the diamond press steel ring, please refer to the utility model patent with application number CN2021100851193.

[0016] A limit adjustment mechanism is provided between the slide rod and the annular body, and the mechanism includes a plurality of radial holes and limit pins which are arranged at equal intervals along the axial direction on the slide rod. The limit pins are inserted into the radial holes and locked by nuts. After the annular body moves to a predetermined position, the pins are inserted into the radial holes to limit and lock the annular body, thereby locking each hook.

[0017] The corners of the hook body are all rounded, so that the hook body is cylindrical as a whole, so that the hook body can be smoothly inserted into the screw hole of the steel ring.

[0018] When the sling of this embodiment is in use, the sling is placed inside the steel ring, and the circular ring body is moved to drive each hook to move up and down along the supporting slide bar, and the opening range between the hooks is adjusted. By adjusting the opening range of the hooks, the hook body at the lower part can be inserted into the screw hole of the steel ring, and the pin shaft is inserted into the radial hole at the lower part of the circular ring body. The circular ring body is limited and locked, and then the hook of the crane or the driving is connected to the lifting ring of the sling, and the steel ring is lifted and moved to a predetermined position. This method of lifting with evenly distributed hooks and simultaneous force can keep the steel ring in a stable state during lifting, thereby improving the safety and stability of the lifting.

[0020] The driving assembly is arranged in the assembly groove and connected to the upper end of the screw rod. The driving assembly includes a driven bevel gear and a driving bevel gear that are vertically meshed with each other. The right-angle steering drive of the driving assembly is realized by the driven bevel gear and the driving bevel gear. The driven bevel gear is coaxially fixedly connected to the upper end of the screw rod. The driving shaft of the driving bevel gear extends laterally from the assembly groove, and a hand wheel is installed at the protruding end of the driving shaft.

[0021] The outer side surface of the support slide rod is threadedly connected with a nut support ring, and the nut support ring moves up and down along the support slide rod through the thread. The threaded limit support strength between the screw rod and the nut sleeve is limited, and long-term stress is prone to thread slippage. The nut support ring is used to assist in limiting the support ring body to reduce the pressure between the screw rod and the nut. A bearing with a seat is fixedly installed between the lower ends of the two arc plates, and the lower end of the screw rod is connected to the bearing with a seat. The bearing with a seat rotates at the bottom to support the screw rod, thereby improving the stability of the screw rod rotation drive.

[0022] The method of using the sling in this embodiment is as follows: ①Place the sling inside the steel ring and connect the lifting ring of the sling to the hook of the crane or crane; ② Turn the handwheel, the handwheel drives the driven bevel gear to rotate through the active bevel gear, the driven bevel gear drives the screw to rotate, the screw drives the nut sleeve and the annular body to move upward synchronously along the supporting slide rod through the thread; ③ As the ring body moves upward, the crossbar at the outer end of the U-shaped seat moves in the long sliding hole in the middle of the hook, and the hook is driven by the sliding pair to swing outward with the hinge point as the center line, and the hook body at the lower end of the hook is synchronously inserted into the screw hole of the steel ring; ④ Start the crane or hoist to lift the sling and the steel ring synchronously. During the lifting process, the hooks evenly distributed on the outside of the hook base are simultaneously stressed to keep the steel ring in a stable state, and the steel ring can reach the specified position in a vertical state. The lifting can be completed without manually adjusting the landing posture.
