Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and in particular to an impact-resistant anchor bolt for a stone crusher. Background Technology

[0002] With the continuous development of mechanization in my country, various mechanical parts have emerged one after another. Among them, the anchor bolts have the characteristic of being able to firmly fix mechanical equipment to the ground, which makes their usage huge nowadays.

[0003] However, in the existing technology, most anchor bolts have low impact resistance and are prone to bending or breaking when subjected to impact, which reduces the service life of the anchor bolts. Moreover, when the anchor bolts are subjected to impact, they may tilt or shake, which reduces the stability of the anchor bolts and thus reduces the supporting effect on the crusher, causing the crusher to malfunction or even be damaged. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where most anchor bolts have low impact resistance, are prone to bending or breaking when subjected to impact, thus reducing the service life of the anchor bolts. Moreover, when the anchor bolts are subjected to impact, they may tilt or shake, reducing the stability of the anchor bolts and thus reducing the supporting effect on the crusher, causing the crusher to malfunction or even be damaged.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an impact-resistant anchor bolt for a stone crusher, comprising: a base, an anchor bolt body fixedly installed on the top of the base, a threaded groove formed at the upper end of the anchor bolt body, and U-shaped plates fixedly installed at the center of both sides of the base, with round shafts fixedly embedded inside the two U-shaped plates, and further comprising:

[0006] Two threaded sleeves are movably fitted onto the outer surfaces of the two circular shafts, and an adjusting screw is threadedly installed inside each of the two threaded sleeves;

[0007] Two connectors are each bearing-mounted at one end of the two adjusting screws. Each connector has a rotatable connecting block inside. An arc-shaped plate is fixedly installed on the opposite surface of each connecting block.

[0008] Two arc-shaped positioning plates are fixedly installed on the top of the two arc-shaped plates, and multiple small dampers are fixedly installed on the outer surface of the top of the two arc-shaped positioning plates.

[0009] Preferably, the plurality of miniature dampers are divided into two groups, and an arc-shaped buffer plate is fixedly installed on the top of each group of miniature dampers.

[0010] The technical effect of adopting the above-mentioned further solutions is that small dampers can improve the buffering and vibration reduction effect. Small dampers convert the kinetic energy of the system into heat energy or other forms of energy and dissipate them through internal friction or other mechanisms, thereby reducing the amplitude of vibration during impact.

[0011] Preferably, multiple springs are fixedly installed at the bottom of each of the two arc-shaped buffer plates, and the multiple springs are divided into two groups on average.

[0012] The technical effect of adopting the above-mentioned further solution is that the arc-shaped buffer plate can play a buffering role.

[0013] Preferably, the other end of both sets of springs is fixedly connected to the outer surface of the arc-shaped positioning plate, and both sets of springs are movably sleeved on the outer surface of the small damper.

[0014] The technical effect of adopting the above-mentioned further solution is that the spring can bear a certain load and provide necessary support. When the impact force disappears, the spring attempts to return to its original shape, generating a reverse restoring force, which drives the arc-shaped buffer plate and the small damper to reset, thereby improving the impact resistance effect.

[0015] Preferably, a fixing plate is fixedly installed on the opposite surfaces of the two arc-shaped plates.

[0016] The technical effect of adopting the above-mentioned further solution is that the two fixed plates can be connected by fitting them together.

[0017] Preferably, the outer surfaces of both sets of fixing plates are provided with fixing holes.

[0018] The technical effect of adopting the above-mentioned further solution is that the two arc-shaped plates are fixed by bolts passing through the fixing holes.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, rotating the adjusting screw inside the threaded sleeve can extend or retract the adjusting screw, adjusting it according to the length of the anchor bolt body after it is fixed. This allows the two arc-shaped plates to be fitted onto the outer surface of the anchor bolt body. When the adjusting screw rotates, the connector mounted on one end of the bearing can rotate, facilitating better contact between the arc-shaped plates and the anchor bolt body. The threaded sleeve can rotate on the outer surface of the round shaft, adjusting according to the support angle. The fixing plates on opposite sides of the two arc-shaped plates are in contact, and the two arc-shaped plates are fixed by bolts passing through the fixing holes, making them more stably fitted onto the outer surface of the anchor bolt body, thus improving the stability and support effect of the anchor bolt body.

[0021] 2. In this utility model, an arc-shaped positioning plate is fixedly installed on the top of each of the two arc-shaped plates, and a small damper is fixedly installed on the top of each of the two arc-shaped positioning plates. An arc-shaped buffer plate is fixedly installed on the top of the small damper. The arc-shaped buffer plate can play a buffering role, and the small damper can improve the buffering and vibration reduction effect. The small damper converts the kinetic energy of the system into heat energy or other forms of energy and dissipates it through internal friction or other mechanisms, thereby reducing the amplitude of vibration during impact. A spring is movably sleeved on the outer surface of the small damper. The spring can bear a certain load and provide necessary support. When the impact force disappears, the spring attempts to return to its original shape, generating a reverse restoring force, thereby driving the arc-shaped buffer plate and the small damper to reset, improving the impact resistance effect.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, such as Figure 1-4 As shown, this utility model provides an impact-resistant anchor bolt for a stone crusher, comprising: a base 1, an anchor bolt body 101 fixedly installed on the top of the base 1, a threaded groove 102 opened at the upper end of the anchor bolt body 101, U-shaped plates 103 fixedly installed at the center of both sides of the base 1, and round shafts 104 fixedly embedded inside the two U-shaped plates 103; further comprising: two threaded sleeves 105, both movably sleeved on the outer surface of the two round shafts 104, and adjusting screws 106 threadedly installed inside the two threaded sleeves 105; two connectors 107, both bearingly installed at one end of the two adjusting screws 106, connecting blocks 108 rotatably installed inside the two connectors 107, and arc-shaped plates 109 fixedly installed on the opposite surfaces of the two connecting blocks 108; fixing plates 114 fixedly installed on the opposite surfaces of the two arc-shaped plates 109; and fixing holes 115 opened on the outer surfaces of the two sets of fixing plates 114.

[0031] In this embodiment, the adjusting screw 106 rotates inside the threaded sleeve 105, which can extend or retract the adjusting screw 106 according to the length of the anchor bolt body 101 after it is fixed. This allows the two arc-shaped plates 109 to be fitted onto the outer surface of the anchor bolt body 101. When the adjusting screw 106 rotates, the connector 107 mounted on one end of the bearing can rotate, which facilitates better contact between the arc-shaped plates 109 and the anchor bolt body 101. The threaded sleeve 105 can rotate on the outer surface of the round shaft 104, which can be adjusted according to the support angle. The fixing plates 114 on the opposite sides of the two arc-shaped plates 109 are in contact, and the two arc-shaped plates 109 are fixed by bolts passing through the fixing holes 115, making them more stably fitted onto the outer surface of the anchor bolt body 101, thereby improving the stability and support effect of the anchor bolt body 101.

[0032] Example 2, as Figure 1-4 As shown, two arc-shaped positioning plates 110 are fixedly installed on the top of two arc-shaped plates 109. Multiple small dampers 113 are fixedly installed on the outer surface of the top of the two arc-shaped positioning plates 110. The multiple small dampers 113 are divided into two groups. Arc-shaped buffer plates 111 are fixedly installed on the top of the two groups of small dampers 113. Multiple springs 112 are fixedly installed on the bottom of the two arc-shaped buffer plates 111. The multiple springs 112 are divided into two groups. The other end of the two groups of springs 112 is fixedly connected to the outer surface of the arc-shaped positioning plates 110. The two groups of springs 112 are movably sleeved on the outer surface of the small dampers 113.

[0033] In this embodiment, an arc-shaped positioning plate 110 is fixedly installed on the top of each of the two arc-shaped plates 109, and a small damper 113 is fixedly installed on the top of each of the two arc-shaped positioning plates 110. An arc-shaped buffer plate 111 is fixedly installed on the top of the small damper 113. The arc-shaped buffer plate 111 can play a buffering role, and the small damper 113 can improve the buffering and vibration reduction effect. The small damper 113 converts the kinetic energy of the system into heat energy or other forms of energy and dissipates it through internal friction or other mechanisms, thereby reducing the amplitude of vibration during impact. A spring 112 is movably sleeved on the outer surface of the small damper 113. The spring 112 can bear a certain load and provide necessary support. When the impact force disappears, the spring 112 attempts to return to its original shape, generating a reverse restoring force, thereby driving the arc-shaped buffer plate 111 and the small damper 113 to reset, improving the impact resistance effect.

[0034] Working principle: During use, rotating the adjusting screw 106 inside the threaded sleeve 105 allows the adjusting screw 106 to extend or retract, adjusting according to the length of the anchor bolt body 101 after fixation. This allows the two arc-shaped plates 109 to fit snugly against the outer surface of the anchor bolt body 101. When the adjusting screw 106 rotates, the connector 107 mounted on one end of the bearing can rotate, facilitating better contact between the arc-shaped plates 109 and the anchor bolt body 101. The threaded sleeve 105 can rotate on the outer surface of the round shaft 104, adjusting according to the support angle. The fixing plates 114 on opposite sides of the two arc-shaped plates 109 fit together, and bolts passing through the fixing holes 115 fix the two arc-shaped plates 109, making them more stably snugly against the outer surface of the anchor bolt body 101, improving the stability and support effect of the anchor bolt body 101. An arc-shaped positioning plate 110 is fixedly installed on the top of each of the two arc-shaped positioning plates 110. A small damper 113 is fixedly installed on the top of each of the two arc-shaped positioning plates 110. An arc-shaped buffer plate 111 is fixedly installed on the top of each small damper 113. The arc-shaped buffer plate 111 can provide a buffering effect, and the small damper 113 can improve the buffering and vibration reduction effect. The small damper 113 converts the kinetic energy of the system into heat energy or other forms of energy and dissipates it through internal friction or other mechanisms, thereby reducing the amplitude of vibration during impact. A spring 112 is movably sleeved on the outer surface of the small damper 113. The spring 112 can bear a certain load and provide necessary support. When the impact force disappears, the spring 112 attempts to return to its original shape, generating a reverse restoring force, thereby driving the arc-shaped buffer plate 111 and the small damper 113 to reset, improving the impact resistance effect.
