Description

[0002] "Multi-cylinder hydraulic cone crusher static balance test" is an important test for the eccentric sleeve assembly and drive assembly of the multi-cylinder hydraulic cone crusher. It aims to ensure that the equipment reaches a balanced state under static conditions to reduce eccentric load, vibration and noise during operation. Since the eccentric sleeve assembly and drive assembly of the multi-cylinder hydraulic cone crusher have a large mass, it is easy to make errors if the static balance test device is used directly for detection. It is necessary to use the test fixture to fix, support, position or apply specific conditions to the eccentric sleeve assembly and drive assembly of the multi-cylinder hydraulic cone crusher to be tested during the test process to ensure the accuracy and reliability of the test; The patent document with the publication number of "CN106092443A" discloses "a static balance test tool for a multi-cylinder hydraulic cone crusher, comprising a flange, a ring-shaped positioning sleeve fixedly connected to the upper end of the flange, and the positioning sleeve is embedded in the lower end of the body assembly of the multi-cylinder hydraulic cone crusher; a first base, the lower end face of the first base is provided with a concave spherical cavity, and the upper end face of the first base is fixedly connected to the middle part of the lower end face of the flange.

The model of the tension pressure sensor 303 is BCLM-1, which is a prior art and will not be elaborated on here.

[0027] Specifically, first adjust the balance of the test fixture through the balance adjustment mechanism 1, and after completing the balance adjustment, clamp and fix the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher through the clamping and fixing mechanism 5. After fixing the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher, connect the corresponding static balance test device. After completing the connection, the auxiliary test mechanism 4 is in a balanced state by adding a counterweight. After the auxiliary test mechanism 4 is balanced, start the driving mechanism 2 to drive the auxiliary test mechanism 4 to rise and fall. During the lifting process, tension or pressure is detected by several balance test mechanisms 3, and the data is fed back to the balance adjustment mechanism 1. When the tension or pressure detected by several balance test mechanisms 3 is equal, it means that the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher under test is balanced in all directions and the static balance state is good. Otherwise, the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher needs to be adjusted with a counterweight.

[0028] Please refer to Figure 6 The balance adjustment mechanism 1 includes a base 101, a platform 102 is arranged directly above the base 101, three adjustment nuts 103 are arranged equidistantly between the base 101 and the platform 102 on the outer circle, and a universal level 104 is fixedly installed on the front end of the platform 102 on the top.

[0029] Specifically, the height of the platform 102 at different positions is adjusted by rotating the adjusting nut 103, and the universal level 104 is used to observe whether the platform 102 is in a horizontal state, so as to facilitate the adjustment of the level of the platform 102, and then make other test tooling components on the upper end of the platform 102 in a horizontal state, thereby reducing the error during the static balance test.

[0030] Please refer to Figure 4 and Figure 6 The balance adjustment mechanism 1 also includes a plurality of lower transfer grooves 107 opened on the top of the platform 102 , the number of the lower transfer grooves 107 is equal to the number of the balance testing mechanism 3 , and the lower end of the lower linkage rod 302 is located inside the lower transfer groove 107 and is movably connected to the platform 102 .

[0031] Specifically, by providing the lower adapter groove 107 to accommodate the lower linkage rod 302 , it is convenient to limit the lower linkage rod 302 , which is beneficial to improving the stability of the balance test mechanism 3 during operation.

[0033] Specifically, after the hydraulic cylinder 201 is started, it drives the spherical body 202 to rise and fall, so that the lifting and falling of the spherical body 202 drives the auxiliary testing mechanism 4 to rise and fall, thereby performing a static balance test of the multi-cylinder hydraulic cone crusher.

The balancing adjustment mechanism 1 also includes a cylinder groove 106 opened in the center of the top of the platform 102. The cylinder body of the hydraulic cylinder 201 is sleeved with the cylinder groove 106. The hydraulic cylinder 201 is fixedly connected to the platform 102 through the fixed blocks 203 and bolts.

[0036] Specifically, by setting up a universal level 402, it is convenient to observe whether the adapter flange 401 is in a horizontal state. When the hydraulic cylinder 201 is started to drive the spherical body 202 to rise, the spherical body 202 enters the concave spherical cavity 404 and lifts up the base 403, thereby facilitating the adapter flange 401 to rise synchronously. The spherical body 202 provides a fulcrum for the auxiliary test mechanism 4. When there is a mass imbalance on the top of the auxiliary test mechanism 4, the balance state of the auxiliary test mechanism 4 changes. In conjunction with the balance test mechanism 3, it is convenient to test the static balance of the multi-cylinder hydraulic cone crusher.

[0039] Please refer to Fig. 9 The clamping and fixing mechanism 5 includes a bottom base plate 501, a plurality of limiting grooves 502 are provided at the top of the bottom base plate 501, a rack clamping card 503 is arranged inside the limiting groove 502, the end of the rack clamping card 503 is connected with a plum handle screw 504 through a bearing, the plum handle screw 504 passes through the bottom base plate 501 and is threadedly connected thereto, one side of the rack clamping card 503 is meshingly connected with a planetary gear 507, the outside of the plurality of planetary gears 507 is provided with the same ring gear 506, the ring gear 506 is meshingly connected with the planetary gear 507, a top sealing plate 508 is arranged on the top of the bottom base plate 501, the top sealing plate 508 is fixedly connected to the bottom base plate 501 by bolts, the shaft of the planetary gear 507 is movably connected to the bottom base plate 501 and the top sealing plate 508, and the ring gear 506 is movably connected to the bottom base plate 501 and the top sealing plate 508.

[0040] Specifically, rotating the plum blossom handle screw 504 drives one of the rack clamping cards 503 to slide along the limiting groove 502, and the rack clamping card 503 drives the planetary gear 507 to rotate, and then cooperates with the ring gear 506 and other planetary gears 507 to drive other rack clamping cards 503 to slide along the limiting groove 502, so as to facilitate the clamping and fixing of the eccentric sleeve assembly or body assembly of multi-cylinder hydraulic cone crushers of different sizes.

[0041] Please refer to Figure 7 and Fig. 9 A plurality of connection blocks 505 are fixedly mounted on the outer ring of the bottom base plate 501 , and the bottom base plate 501 is fixedly connected to the adapter flange 401 through the connection blocks 505 and bolts.

[0042] Please refer to Figure 4 and Figure 6 The balance adjustment mechanism 1 also includes a control panel 105 fixedly installed on one side of the platform 102 , and the control panel 105 is communicatively connected with the tension and pressure sensor 303 .

[0043] Specifically, during the lifting process, the tension or pressure sensors 303 in the balance test mechanism 3 are used to detect the tension or pressure, and the data is fed back to the control panel 105 in the balance adjustment mechanism 1, which is convenient for collecting the detection data and provides a reference for engineers to adjust the counterweight of the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher.

[0044] How it works First, adjust the balance of the test fixture through the balance adjustment mechanism 1. After completing the balance adjustment, turn the plum handle screw 504 to drive one of the rack clamping cards 503 to slide along the limit groove 502, and drive the planetary gear 507 to rotate through the rack clamping card 503, and then cooperate with the ring gear 506 and other planetary gears 507 to drive other rack clamping cards 503 to slide along the limit groove 502, so as to facilitate the clamping and fixing of the eccentric sleeve assembly or body assembly of the multi-cylinder hydraulic cone crusher of different sizes. After fixing the eccentric sleeve assembly or body assembly of the multi-cylinder hydraulic cone crusher, connect the corresponding static balance test device. After completing the connection, the auxiliary test mechanism 4 is in a balanced state by adding a counterweight. After the auxiliary test mechanism 4 is balanced, the hydraulic cylinder 201 starts to drive the spherical body 202 to rise and fall, so as to facilitate the lifting of the auxiliary test mechanism 4 through the lifting of the spherical body 202. The surface body 202 provides a fulcrum for the auxiliary test mechanism 4. When there is a mass imbalance on the top of the auxiliary test mechanism 4, the balance state of the auxiliary test mechanism 4 changes. The tension or pressure sensors 303 in the balance test mechanisms 3 are used to detect the tension or pressure, and the data is fed back to the control panel 105 in the balance adjustment mechanism 1, which is convenient for collecting the detection data and providing a reference for engineers to adjust the counterweight of the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher. The control panel 105 model is HM7A-32MRT, which is the prior art and will not be described in detail here. When the tension or pressure detected by the several balance test mechanisms 3 is equal, it means that the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher under test is balanced in all directions and is in a good static balance state. Otherwise, the eccentric sleeve assembly or the body assembly of the multi-cylinder hydraulic cone crusher needs to be counterweight adjusted.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
