DETAILED DESCRIPTION

[0034] In order to clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0036] Embodiment 1

[0037] See also Figure 1-15The present invention provides a weight structure for preventing resonant vibration, including: an upper weight assembly 100, a lower weight assembly 200 and a vibration reduction connection seat 300, the vibration reduction connection seat 300 has a joint for connecting with a wire rope 500; the top and bottom of the upper weight assembly 100 are respectively connected to the vibration reduction connection seat 300 and the lower weight assembly 200; the lower weight assembly 200 is equipped with a center of gravity adjustment assembly 400.

[0038] The working principle and beneficial effects of the above technical solution are:

[0039] The weight structure of the present invention prevents the generation of resonant jitter, and a joint for connecting to the wire rope 500 is provided on the vibration reduction connecting seat 300, so as to be connected to the wire rope 500. The vibration reduction connecting seat 300 is connected above the upper weight assembly 100, which can reduce the vibration amplitude, and can play a certain degree of buffering and vibration reduction role, thereby improving the balance stability of the present invention. The present invention adopts a split structural setting, and the upper weight assembly 100 and the lower weight assembly 200 can be disassembled to facilitate inspection, repair or replacement, thereby reducing the repair cost after damage; and the lower weight assembly is equipped with a center of gravity adjustment assembly 400, which can automatically lower the center of gravity of the present invention when rotating for shoulder transfer processing, thereby improving the stability of the present invention, and the faster the rotation speed, the lower the center of gravity, thereby meeting the rotation speed requirements during different shoulder transfer processing.

[0040] The vibration reduction connecting seat 300 includes: a seat body 301 with multiple vertical slots, a horizontal column 302 assembled in the vertical slots, a curved pressure arm 303 with a middle part rotated on the horizontal column 302, and a hanger 304 hinged on the straight arm at the lower part of the curved pressure arm 303; the curved arms at the upper parts of the multiple curved pressure arms 303 are in contact with the wire rope 500; and the multiple hangers 304 are rotated on the upper weight assembly 100.

[0041] In the vibration reduction connecting seat 300, multiple hangers 304 are rotatably arranged on the upper weight assembly 100 for connecting with the upper weight assembly 100. The upper weight assembly 100 can drive one end of the multiple hangers 304 to move downward, and the other ends of the multiple hangers 304 drive the lower straight arms of the multiple bent pressure arms 303 to move downward, thereby driving the multiple bent pressure arms 303 to rotate on the multiple cross columns 302, so that the upper bent arms of the multiple bent pressure arms 303 are pressed against the wire rope 500 together; when the feed rate is high, the greater the force generated on the upper weight assembly 100 and the lower weight assembly 200 of the present invention, the greater the force of the upper weight assembly 100 driving the bent pressure arms 303 to press against the wire rope 500 through the hanger 304, making the wire rope 500 more stable, and the connection between the wire rope 500 and the present invention is also more stable, reducing the frequency and amplitude of shaking or vibration.

[0042] The bending arm at the upper part of the bending pressure arm 303 is provided with an anti-shake pressure strip 305, and the arc-shaped pressure surface of the anti-shake pressure strip 305 contacts the steel wire rope 500. The provision of the anti-shake pressure strip 305 increases the area of ​​the steel wire rope 500 tightened by the present invention, which not only improves the tightening effect, but also improves the stability of the steel wire rope 500 during movement. By limiting the side of the steel wire rope 500, the steel wire rope 500 will not shake easily, and the anti-shake pressure strip 305 is pressed against the steel wire rope 500, which can reduce the traction force between the bottom of the steel wire rope 500 and the vibration reduction connection seat 300 to a certain extent, so that the force received by the connection end of the present invention and the steel wire rope 500 can be dispersed to different positions of the steel wire rope 500, preventing the steel wire rope 500 from breaking, and improving the stability of the connection between the present invention and the steel wire rope 500.

[0043] The anti-shake pressure strip 305 is made of elastic metal, and a plurality of anti-slip edges are arranged on the arc-shaped pressure surface of the anti-shake pressure strip 305 to increase friction and enhance contact effect.

[0044] The vibration reduction connection seat 300 further includes: a plurality of suspension shafts 306 slidably mounted on the seat body 301, the two ends of the suspension shafts 306 being respectively connected to the clamp ring 1 307 and the upper weight assembly 100; and an elastic vibration reduction element 308 being mounted on the shaft section of the suspension shaft 306 between the clamp ring 1 307 and the seat body 301. The upper weight assembly 100 can drive the plurality of suspension shafts 306 to slide slightly on the seat body 301, and when the plurality of suspension shafts 306 slide downward, they can drive the plurality of clamp rings 1 307 to compress the elastic vibration reduction element 308, which can be a spring or a shock-absorbing washer, thereby effectively reducing the vibration frequency and improving the balance of the present invention.

[0045] Embodiment 2

[0046] See also Figure 1-15 The upper weight assembly 100 includes an upper weight body 101 connected to the vibration reduction connection seat 300, and an internal thread interface 102 is provided at the bottom of the upper weight body 101; the lower weight assembly 200 includes an external thread joint 201 screwed to the internal thread interface 102 and a lower weight body 202 fixed to the bottom of the external thread joint 201; an elastic gasket is provided at the connection between the external thread joint 201 and the internal thread interface 102.

[0047] The working principle and beneficial effects of the above technical solution are:

[0048] The internal threaded interface 102 of the upper weight assembly 100 can be threadedly connected to the external threaded joint 201 of the lower weight assembly 200, which is convenient for disassembly or assembly and can be replaced separately after damage. An elastic gasket is provided at the connection between the external threaded joint 201 and the internal threaded interface 102 to improve the stability of the connection between the upper weight assembly 100 and the lower weight assembly 200.

[0049] The lower hammer body 202 has an upper counterweight liquid storage chamber 203, a counterweight liquid guide hole 204 and a lower counterweight storage chamber 205 that are connected from top to bottom. The upper counterweight liquid storage chamber 203 is connected to a sliding hole 1 provided on the upper surface of the lower hammer body 202, and the sliding hole 1 is located in the hollow groove of the external threaded joint 201. The two ends of the sliding shaft 1 207 that is sealed and slides in the sliding hole 1 are respectively connected to the clamp ring 208 and the upper extrusion disk 209; the compression spring structure 208 connected between the clamp ring 208 and the upper surface of the lower hammer body 202 is connected to the compression spring structure 209. 10 is sleeved on the sliding shaft 207; the upper extrusion plate 209 is sealingly slidably arranged on the inner wall of the upper counterweight liquid storage chamber 203, and the upper extrusion plate 209 is connected with the lower extrusion plate 212 sealingly slidably arranged on the inner wall of the lower counterweight storage chamber 205 through the lifting rod 211, and a guide channel is formed between the lifting rod 211 passing through the counterweight liquid guide hole 204 and the inner wall of the counterweight liquid guide hole 204; the counterweight oil is filled between the bottom surface of the upper counterweight liquid storage chamber 203 and the lower surface of the upper extrusion plate 209, and the lower end of the lower extrusion plate 212 is connected to the center of gravity adjustment component 400.

[0050] The structural setting of the lower hammer body 202 is that under normal conditions, the upper extrusion plate 209 remains in contact with the top surface of the upper counterweight liquid storage chamber 203 under the elastic force of the compression spring structure 210. At this time, the upper counterweight liquid storage chamber 203 and the guide channel are filled with high-temperature resistant counterweight oil. When it is necessary to control the center of gravity to drop, the center of gravity adjustment component 400 is controlled to drive the lower extrusion plate 212 to slide downward on the inner wall of the lower counterweight storage chamber 205. At this time, the lower extrusion plate 212 can drive the lifting rod 211 and the upper extrusion plate 209 to move downward. When the upper extrusion plate 209 moves downward, the counterweight oil in the upper counterweight liquid storage chamber 203 and the guide channel can be moved downward to the counterweight storage chamber. 205 is pressurized and sent into the lower counterweight storage chamber 205, so that the counterweight oil enters the lower counterweight storage chamber 205, so that the center of gravity of the present invention is lowered, so as to meet the use requirements in different situations. The structure of the present invention is changed to improve the stability of the present invention when it is used, and the structure is simple and easy to operate. When the center of gravity needs to be raised, the lower extrusion plate 212 is controlled to rise through the center of gravity adjustment component 400, and the lower extrusion plate 212 can press the counterweight oil back into the upper counterweight liquid storage chamber 203. The bottom of the lower hammer body 202 can be an end cover sealed by multiple bolts, or it can be a welded end cover. It can be designed according to actual needs. Before connecting the end cover, the above structure is installed or adjusted.

[0051] A counterweight adjustment chamber 213 is provided at the lower end of the lower hammer body 202, and the upper part of the counterweight adjustment chamber 213 is connected to the lower counterweight storage chamber 205 through a second slide hole; the center of gravity adjustment component 400 includes an adjustment shaft 401 fixedly connected to the center of the lower surface of the lower extrusion plate 212, the middle part of the adjustment shaft 401 is slidably arranged in the second slide hole, and a clamping ring 3 402 at the bottom of the adjustment shaft 401 is evenly rotated around one end of multiple gravity swing arms 403, and the other ends of the multiple gravity swing arms 403 are connected to multiple counterweight adjustment blocks 404, and the multiple counterweight adjustment blocks 404 are slidably arranged on multiple transverse guide rails 405, and the multiple transverse guide rails 405 are evenly arranged around the inner wall of the counterweight adjustment chamber 213 with the axis of the adjustment shaft 401 as the center; a compression spring member 406 fixedly connected between the inner wall of the counterweight adjustment chamber 213 and the counterweight adjustment block 404 is sleeved on the transverse guide rail 405.

[0052] When a single crystal silicon rod is pulled in a single crystal furnace for shoulder treatment, the weight structure of the present invention needs to rotate. The weight structure provides the gravity force and vibration force required in the heat treatment process to ensure uniform heating and treatment of the single crystal material in the furnace, to ensure that the single crystal material is subjected to uniform force, to avoid stress concentration or uneven deformation; under normal conditions, a plurality of counterweight adjustment blocks 404 are slidably disposed on a plurality of transverse guide rails 405, and are brought close to each other under the elastic force of a plurality of compression spring members 406. When the weight structure of the present invention rotates, under the action of gravity inertia, the plurality of counterweight adjustment blocks 404 slide outward on the plurality of transverse guide rails 405 and compress the plurality of compression spring members 406. When the plurality of counterweight adjustment blocks 404 slide outward, they can drive one end of the plurality of gravity swing arms 403 to slide outward. At this time, the other end of the plurality of gravity swing arms 403 drives the clamping ring three 402 to move downward. When 402 moves downward, the lower extrusion plate 212 is driven by the adjusting shaft 401 to slide downward in the lower counterweight storage chamber 205, so that the counterweight oil enters the lower counterweight storage chamber 205, thereby automatically lowering the center of gravity of the present invention; and the faster the rotation speed during the shoulder turning process, the greater the distance that the multiple counterweight adjustment blocks 404 slide outward, and finally the greater the distance that the lower extrusion plate 212 is driven to move downward, the more counterweight oil there is in the lower counterweight storage chamber 205, and the lower the center of gravity at this time; when the rotation stops, the multiple counterweight adjustment blocks 404 are reset under the elastic force of the multiple compression spring members 406, and cooperate with the elastic reset of the retaining ring 208 by the compression spring structure 210, and the counterweight oil returns to the upper counterweight liquid storage chamber 203; it should be noted that the counterweight oil in the present invention fills the area between the lower extrusion plate 212, the guide channel and the upper extrusion plate 209, so that the present invention will not cause an unstable center of gravity due to the up and down fluctuations of insufficient counterweight oil.

[0053] The diameter of the counterweight adjustment chamber 213 is larger than the diameter of the lower counterweight storage chamber 205, the diameter of the lower counterweight storage chamber 205 is larger than the diameter of the upper counterweight liquid storage chamber 203, and the diameter of the upper counterweight liquid storage chamber 203 is larger than the diameter of the counterweight liquid guide hole 204. The diameter of the lower counterweight storage chamber 205 is controlled to be larger than the diameter of the upper counterweight liquid storage chamber 203, so that the horizontal position of the overall counterweight oil moving downward can be lower and more uniform, thereby improving the effect of lowering the center of gravity.

[0054] A double-sided rack 214 is fixedly connected to the second retaining ring 208, and two gears 215 are meshed on both sides of the double-sided rack 214. The two gears 215 are fixedly connected to two rotating tubes 216 that are relatively rotated in the hollow groove of the external threaded joint 201. Sliding screws 206 are threaded in the two rotating tubes 216. A transverse rod is fixedly connected between the two sliding screws 206. A through hole is provided on the side wall of the external threaded joint 201 for the two sliding screws 206 to pass through, and an annular slot 103 is provided in the internal threaded interface 102 of the upper hammer body 101 for the two sliding screws 206 to pass through.

[0055] Since the internal thread interface 102 of the upper weight assembly 100 can be threadedly connected with the external thread connector 201 of the lower weight assembly 200, the present invention may have the probability of loosening during the rotation process. Therefore, the above structure is designed to prevent the internal thread interface 102 and the external thread connector 201 from loosening. During rotation, as the multiple counterweight adjustment blocks 404 slide outward on the multiple cross guide rails 405 and compress the multiple compression spring members 406, the upper extrusion plate 209, the lifting rod 211 and the lower extrusion plate 212 move downward, the lower extrusion plate 212 simultaneously drives the sliding shaft 1 207 to move downward, and the sliding shaft 1 207 drives the retaining ring 208 to move downward, which can drive the double-sided rack 214 to move downward. When the double-sided rack 214 moves downward, it meshes with the two gears 215 to rotate, and the two gears 215 drive the rotating tube 216 to rotate. Since the two sliding screws 206 are fixedly connected with the cross connecting rod, the two rotating tubes 216 can change their connection with the two sliding screws 206 when they rotate. When the double-sided rack 214 moves upward and resets, the two sliding screws 206 are disengaged from the annular slot 103 and retracted to the inner side of the external threaded joint 201, so that the external threaded joint 201 and the internal threaded joint 102 are easy to disassemble, and the upper weight assembly 100 and the lower weight assembly 200 are convenient to separate.
