Description

Technical Field

[0001] The invention relates to a shock-absorbing support seat for sand and gravel processing equipment and a working method thereof, belonging to the technical field of shock-absorbing support seats. Background Art

[0002] Sand and gravel processing equipment is a kind of equipment used in mines to crush ore into machine-made sand. Because the sand making machine vibrates greatly during processing, a shock absorber will be installed at the bottom of the sand making machine to reduce the vibration of the sand making machine body during sand making, so that the various components of the sand making machine are not easy to loosen and cause damage.

[0003] However, the existing shock absorbers are directly fixed to the bottom of the sand making machine. The spring on the shock absorber needs to bear the weight of the sand making machine for a long time, which causes the spring on the shock absorber to be overloaded for a long time, resulting in plastic deformation, and reducing the elastic shock absorbing performance of the spring. The spring on the shock absorber is constantly subjected to cyclic loads such as compression and stretching during the long-term and frequent shock absorption process. The spring is not subjected to material fatigue relief operations and a certain recovery time is not given to the spring. As a result, the internal structure of the metal spring will accelerate the accumulation of damage, causing the spring to become weak and break faster, shortening the service life of the spring on the shock absorber. In view of the above shortcomings, the present invention proposes a shock-absorbing support seat for sand and gravel processing equipment and a working method thereof. Summary of the Invention

[0044] The lifting support member 236 includes a cylinder 2361 , and a rotating seat 2362 is provided on the top surface of the cylinder 2361 , and a supporting cushion 2363 is provided on the top surface of the rotating seat 2362 . The supporting cushion 2363 is made of rubber.

[0045] Working principle:

[0046] The following working methods are included:

[0047] For the pressure-free operation of each shock-absorbing component on the shock-absorbing switching device 23, when the main body 3 of the sand and gravel processing equipment is shut down every night, the lifting support members 236 on the four shock-absorbing switching devices 23 are started and raised through the oil cylinder 2361, so that the supporting cushion 2363 rises and is sleeved in the lifting support member embedding hole 223, pushing the shock-absorbing frame 22 horizontally, so that the sleeve engagement between the first shock-absorbing component 233 or the second shock-absorbing component 234 in the high position on the four shock-absorbing switching devices 23 and the shock-absorbing frame 22 is disengaged, so that the first shock-absorbing component 233 and the second shock-absorbing component 234 are in a non-load-bearing state, which is used to relieve material fatigue of the springs on each shock-absorbing component and avoid plastic deformation caused by long-term overload, thereby extending the service life of each shock-absorbing component and improving the shock-absorbing performance.

[0048] In addition, the switching operation of the first shock absorbing assembly 233 and the second shock absorbing assembly 234 on the shock absorbing switching device 23 is carried out. During the period when the main body 3 of the sand and stone processing equipment is stopped every night, the lifting support member 236 has risen to lift the shock absorbing frame 22 and separate from the first shock absorbing assembly 233 and the second shock absorbing assembly 234. First, the switching mechanism 235 is pushed and pulled left and right to switch between the first shock absorbing assembly 233 and the second shock absorbing assembly 234. Then, the rotating seat group 231 rotates 180 degrees left and right to switch between the first shock absorbing assembly 233 and the second shock absorbing assembly 234 after the lifting switch. The shock-absorbing component that is raised to the highest position can be vertically aligned with the shock-absorbing component embedding hole 222, so that the lifting support member 236 can subsequently drive the shock-absorbing frame 22 to descend horizontally so that the shock-absorbing component embedding hole 222 and the locking head 2333 can be exactly locked and positioned, so that the first shock-absorbing component 233 or the second shock-absorbing component 234 can be strengthened again one day after each day of use to relieve material fatigue and avoid plastic deformation caused by long-term overload. The above operation is also suitable for timely switching when the shock-absorbing component is damaged during use, reducing the downtime and maintenance time of the sand and gravel processing equipment body 3 during use, and improving production efficiency.

[0049] It should be noted that the working method of the switching mechanism 235 is shown in the attached Figure 3 、 6 , 8, 9. First, the telescopic device 2354 retracts to the left and pulls the switching push slider 2352 to slide to the left on the switching slide 2351. During this process, the supporting roller seat on the second shock-absorbing assembly 234 will move to the right and down the walking slope 23522 on the right to reach the low-position support platform 23523 on the right, causing the second shock-absorbing assembly 234 to drop vertically. At the same time, the supporting roller seat on the first shock-absorbing assembly 233 moves upward from the walking slope 23522 on the left to reach the high-position support platform 23521, causing the first shock-absorbing assembly 233 to rise vertically, completing the high-low position lifting and lowering switching between the first shock-absorbing assembly 233 and the second shock-absorbing assembly 234.

[0050] In addition, since a strong magnetic plate 23524 is provided on the bottom surface of the switching push slider 2352, the switching push slider 2352 has magnetism, and each roller 23342 is made of iron, the switching push slider 2352 has a downward suction and pulling force on the supporting roller seat, allowing the shock-absorbing slide 2331 to descend normally in the first shock-absorbing component slide 2322, and there will be no problem of being stuck and unable to descend due to lack of force.

[0051] In addition, each roller 23342 can only move in a longitudinal arrangement between the high-position support platform 23521, the two walking slopes 23522, and the two low-position support platforms 23523. Therefore, the first shock-absorbing assembly slide 2322 and the second shock-absorbing assembly slide 2323 are both designed in a hexagonal shape, which can position the lifting direction of the shock-absorbing slide 2331, thereby achieving the purpose of preventing each roller 23342 from changing direction.

[0052] In addition, when the rotating seat assembly 231 rotates 180° left and right to perform the left and right switching operation between the first shock absorbing component 233 and the second shock absorbing component 234, the lifting support member 236 has risen to lift the shock absorbing frame 22, and the top surface of the supporting pad 2363 is in a soft resistance state with the lifting support member embedding hole 223. When the rotating seat assembly 231 rotates left and right, it will also cause the oil cylinder 2361 to rotate 180° left and right. At this time, the rotating seat 2362 can separate the oil cylinder 2361 and the supporting pad 2363, so that the supporting pad 2363 will not rotate with it, thereby ensuring the stability of the shock absorbing frame 22 after it is lifted.

[0053] In addition, the working method of the rotating seat assembly 231 is conventional technology and will not be described in detail here.

[0054] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

9. The shock-absorbing support seat for sand and stone processing equipment according to claim 8, characterized in that: The lifting support member (236) comprises an oil cylinder (2361), a rotating seat (2362) is provided on the top surface of the oil cylinder (2361), and a supporting cushion (2363) is provided on the top surface of the rotating seat (2362), and the supporting cushion (2363) is made of rubber.

10. A method for operating the shock-absorbing support seat for sand and gravel processing equipment according to claim 9, characterized in that: The working method is as follows: For the non-pressure-bearing operation of each shock-absorbing component on the shock-absorbing switching device (23), when the main body (3) of the sand and gravel processing equipment is shut down every night, the lifting support members (236) on the four shock-absorbing switching devices (23) are started and raised through the oil cylinder (2361), so that the supporting cushion (2363) rises and is sleeved in the lifting support member embedded hole (223), and the shock-absorbing frame (22) is pushed up horizontally, so that the sleeve engagement between the first shock-absorbing component (233) or the second shock-absorbing component (234) in the high position of the four shock-absorbing switching devices (23) and the shock-absorbing frame (22) is disengaged, so that the first shock-absorbing component (233) and the second shock-absorbing component (234) are in a non-load-bearing state, which is used to relieve material fatigue of the springs on each shock-absorbing component and avoid plastic deformation caused by long-term overload, thereby extending the service life of each shock-absorbing component and improving the shock-absorbing performance; In addition, the switching operation of the first shock absorbing assembly (233) and the second shock absorbing assembly (234) on the shock absorbing switching device (23) is carried out. During the period when the sandstone processing equipment body (3) is stopped every night, the lifting support member (236) has risen to lift the shock absorbing frame (22) and separate from the first shock absorbing assembly (233) and the second shock absorbing assembly (234). First, the switching mechanism (235) is pushed and pulled left and right to switch between the first shock absorbing assembly (233) and the second shock absorbing assembly (234). Then, the rotating seat group (231) is rotated 180 degrees left and right to switch between the first shock absorbing assembly (233) and the second shock absorbing assembly (234). The right position is changed so that the shock absorbing component that has risen to the highest position can be vertically aligned with the shock absorbing component embedded hole (222), so that the lifting support member (236) can subsequently drive the shock absorbing frame (22) to descend horizontally so that the shock absorbing component embedded hole (222) and the locking head (2333) can be just pressed and locked in position, so that the first shock absorbing component (233) or the second shock absorbing component (234) can be strengthened again one day after each day of use to relieve material fatigue and avoid plastic deformation caused by long-term overload. The above operation is also suitable for timely switching when the shock absorbing component is damaged during use, thereby reducing the downtime and maintenance time of the sand and gravel processing equipment body (3) during use and improving production efficiency.
