Description

Technical Field

[0001] The utility model relates to the technical field of turning gears, in particular to a turning gear device for a crusher. Background Art

[0002] Cranking means turning the rotor driven by the motor several times by human power before starting the motor, in order to determine whether the load driven by the motor (i.e. the mechanical or transmission part) is stuck and the resistance is increased, so as not to increase the starting load of the motor and damage the motor (i.e. burn it out). Therefore, generally, cranking is required when the motor is started again after stopping for a shift (8 hours).

[0025] For large crushers, due to the large size and weight of the rotor, when the winch needs to be repaired, a guide chain or a linear motion winch device is usually used. The use of a guide chain is labor-intensive and time-consuming, and is not safe and reliable, while the linear motion winch device is inflexible and prone to failure.

[0026] Based on this, the present application provides a winch device for a crusher to simplify the winch work of the crusher and improve the winch efficiency of the crusher.

[0027] The following describes in detail the technical solutions of one or more embodiments of the present application through specific embodiments. A disc brake device for a crusher, such as Figure 1As shown, the rotor 10 of the crusher is driven to rotate by the main shaft 1, and the winch device 2 includes a winch mechanism 21 and a connecting mechanism 22. The output motion of the power output end 211 of the winch mechanism 21 is a circular motion. The power output end 211 is fixedly connected to the connecting mechanism 22, and the power output end 211 is connected to the main shaft 1 through the connecting mechanism 22.

[0028] In this embodiment, the output motion of the power output end 211 of the cranking mechanism 21 is a circular motion, and the connecting mechanism 22 is fixedly connected to the power output end 211, so that the circular motion of the power output end 211 can be transmitted to the connecting mechanism 22, and the power output end 211 is connected to the main shaft 1 through the connecting mechanism 22, so that the main shaft 1 can rotate under the drive of the circular motion of the power output end 211, thereby rotating the rotor 10 to achieve the purpose of cranking. Using the cranking device 2 to achieve cranking can simplify the cranking process and improve the simplicity of cranking.

[0029] Specifically, the power input end of the cranking mechanism 21 can move linearly, and its power source can be a hydraulic structure or a motor structure, which can provide power support during cranking and save manpower.

[0030] Exemplarily, the winching mechanism 21 is a hydraulic worm gear structure, whose power source is a hydraulic device, the power input end is a worm, and the power output end 211 is a worm wheel, that is, the hydraulic pressure pushes the linear motion of the worm to transform into the circular motion of the worm wheel. When performing the winching operation, starting the hydraulic device can make the worm wheel drive the main shaft 1 to rotate, and then make the rotor 10 rotate, so as to realize the winching.

[0031] In some embodiments, Figure 2 , Figure 3 As shown, the connection mechanism 22 includes a connection plate 221 and a connection member 222 . The connection plate 221 is fixedly connected to the power output end 211 , and the connection plate 221 is connected to the main shaft 1 via the connection member 222 .

[0032] The connecting plate 221 performs circular motion with the power output end 211, and the connecting member 222 connects the connecting plate 221 and the main shaft 1, so that the main shaft 1 can perform circular motion with the connecting plate 221, thereby enabling the main shaft 1 to drive the rotor 10 to rotate, thereby realizing the turning. The connecting plate 221 and the connecting member 222 can transmit the circular motion of the power output end 211 to the main shaft 1, and then transmit it from the main shaft 1 to the rotor 10. The arrangement of the connecting plate 221 and the connecting member 222 enables the circular motion of the power output end 211 to be stably transmitted to the main shaft 1, thereby ensuring the stable operation of the turning.

[0033] In some embodiments, Figure 2 As shown, the connecting member 222 includes a fixing plate 2221 , a connecting bolt 2223 and a connecting pin 2222 , the fixing plate 2221 is fixedly connected to the connecting plate 221 via the connecting bolt 2223 , and the fixing plate 2221 is connected to the main shaft 1 via the connecting pin 2222 .

[0034] The connecting pin 2222 and the fixing plate 2221 are fixedly connected, and the fixing plate 2221 and the connecting plate 221 are fixedly connected via the connecting bolt 2223. The connecting pin 2222 is connected to the main shaft 1, thereby realizing the connection between the connecting plate 221 and the main shaft 1, so that the connecting plate 221 can drive the main shaft 1 to move, thereby ensuring that the turning device 2 can stably perform the turning operation.

[0035] Specifically, there are multiple connecting pins 2222, and the multiple connecting pins 2222 are located on the same side of the fixed plate 2221. One end of each connecting pin 2222 is fixedly connected to the fixed plate 2221, and the other end is connected to the main shaft 1. By providing multiple connecting pins 2222 connected to the main shaft 1, the multiple connecting pins 2222 can simultaneously apply forces in the same direction to the main shaft 1, making the rotation of the main shaft 1 easier, thereby simplifying the turning work.

[0036] In some embodiments, Figure 3 As shown, a thread groove 3 is provided on the side of the connecting plate 221 away from the main shaft 1, and a first through hole 4 is provided on the fixing plate 2221 corresponding to the thread groove 3. The connecting bolt 2223 passes through the first through hole 4 and is threadedly connected to the thread groove 3, so as to fix the fixing plate 2221 with the connecting plate 221. Under the joint action of the connecting bolt 2223, the first through hole 4 and the thread groove 3, the fixing plate 2221 is fixedly connected with the connecting plate 221, so that the motion energy of the connecting plate 221 is transmitted to the fixing plate 2221, and then transmitted to the connecting pin 2222 and the main shaft 1. The arrangement of the connecting bolt 2223, the first through hole 4 and the thread groove 3 ensures the stable connection between the fixing plate 2221 and the connecting plate 221, which has the significance of stable transmission for the circular motion transmission of the power output end 211, and ensures the stable operation of the turning gear.

[0037] In some embodiments, Figure 3 , Figure 5As shown, a second through hole 5 is provided on the connecting plate 221, and a groove 6 is provided on the end face of the main shaft 1. The groove 6 is arranged corresponding to the second through hole 5. One end of the connecting pin 2222 is connected to the fixing plate 2221, and the other end passes through the second through hole 5 and extends into the groove 6 to connect the fixing plate 2221 with the main shaft 1.

[0038] In this embodiment, the second through hole 5 is provided to facilitate the connection between the connecting pin 2222 and the main shaft 1. The connecting pin 2222 extends into the groove 6 on the end surface of the main shaft 1, so that the force perpendicular to the axial direction of the connecting plate 221 generated when the connecting pin 2222 makes a circular motion with the connecting plate 221 acts in the groove 6, and then acts on the main shaft 1, so that the main shaft 1 rotates, and then drives the rotor 10 to rotate, realizing the turning. The provision of the groove 6 facilitates the connection between the connecting pin 2222 and the main shaft 1, and also ensures that the connecting pin 2222 applies a force to the main shaft 1, so that the main shaft 1 rotates.

[0039] In some embodiments, there are four connecting bolts 2223, the fixing plate 2221 is provided with four first through holes 4 for the connecting bolts 2223 to pass through, and the connecting plate 221 is provided with four thread grooves 3 for the connecting bolts 2223 to be inserted into. The four connecting bolts 2223 are provided to fix the fixing plate 2221 to the connecting plate 221, so that the fixing plate 2221 and the connecting plate 221 are stably fixedly connected, so that the connecting plate 221 can stably transmit the force to the fixing plate 2221.

[0040] In some embodiments, there are four connecting pins 2222, and the connecting plate 221 is provided with four second through holes 5 for the connecting pins 2222 to pass through. The end surface of the main shaft 1 is provided with four grooves 6 for the connecting pins 2222 to be inserted into. Driven by the fixing plate 2221 and the connecting plate 221, the four connecting pins 2222 make circular motion with the power output end 211, and the four connecting pins 2222 simultaneously apply the same force to the main shaft 1, so that the main shaft 1 rotates. The four connecting pins 2222 can rotate the main shaft 1 when the output power of the power output end 211 is low, thereby reducing the energy consumption of the winch mechanism 21.

[0041] Exemplarily, the winching mechanism 21 is a hydraulic worm gear mechanism, the winching mechanism 21 is fixed on a bearing seat 01 of the crusher, the main shaft 1 is connected to the bearing seat 01 through a bearing, the main shaft 1 rotates relative to the bearing seat 01, and the bearing seat 01 is fixed relative to the crusher. Therefore, the winching mechanism 21 is fixed on the bearing seat 01, which can provide a fixing force to the winching mechanism 21, so that the power output end 211 of the winching mechanism 21 has sufficient stabilizing force when rotating, so that the winching mechanism 21 is stably set. The connecting plate 221 is arranged opposite to the power output end 211 and is fixedly connected by a plurality of bolts. The connecting plate 221 is arranged corresponding to the end surface of the main shaft 1 close to the bearing seat 01. The fixing plate 2221 is provided with four connecting pins 2222. The connecting pins 2222 and the fixing plate 2221 are fixed by welding. The fixing plate 2221 is provided with four first through holes 4. The four connecting bolts 2223 respectively pass through the first through holes 4 and are threadedly connected with the thread grooves 3 on the connecting plate 221, so that the fixing plate 2221 is fixedly connected to the connecting plate 221. The connecting plate 221 is provided with four second through holes 5. The four connecting pins 2222 pass through the second through hole 5 and extend into the four grooves 6 on the end face of the main shaft 1 to drive the hydraulic worm gear mechanism. The power output end 211, i.e., the worm gear, drives the connecting plate 221 to rotate, and the connecting plate 221 drives the fixed plate 2221 to rotate, and the fixed plate 2221 drives the connecting pins 2222 to rotate. The connecting pins 2222 are located in the grooves 6. When rotating, they will apply a certain force to the grooves 6 to enable the grooves 6 to rotate. Accordingly, the main shaft 1 is subjected to the force in the same direction applied by the four connecting pins 2222 to achieve rotation, and then the rotor 10 rotates to achieve turning. After the cranking is completed, the four connecting bolts 2223 are taken out, the connection between the fixed plate 2221 and the connecting plate 221 is released, the connecting pin 2222 is pulled out from the groove 6 to make it leave the second through hole 5, so that the connecting pin 2222 is away from the main shaft 1, and then the fixed plate 2221 and the connecting plate 221 are fixedly connected by the connecting bolts 2223, so that the connecting member 222 is located on the connecting plate 221, and the connecting pin 2222 is removed from the connecting plate 221 and passed through the second through hole 5 into the groove 6 when waiting for the next cranking, and then the fixed plate 2221 and the connecting plate 221 are fixed by the connecting bolts 2223.The turning mechanism 21 is fixedly connected to the bearing seat 01, and the connecting piece 222 is detachably fixedly connected to the connecting plate 221. Such an arrangement can avoid taking out and reinstalling the turning device 2 every time the turning is performed, thereby simplifying the turning process. Each time the turning is performed, it is only necessary to remove the connecting piece 222, change its direction, and connect it to the main shaft 1. When the turning is completed, the connecting piece 222 is removed, changed its direction, and fixed on the connecting plate 221, thereby avoiding the situation where the connecting piece 222 is lost when the turning is not performed.

[0042] In some embodiments, Figure 4 As shown, the barring device 2 further includes a protection plate 23, which can be rotatably disposed on a side of the connecting plate 221 away from the main shaft 1, and the protection plate 23 is provided with a third through hole 7 for the connecting pin 2222 to pass through. The protection plate 23 is located between the fixing plate 2221 and the connecting plate 221, and the third through hole 7 is provided on the protection plate 23 so as not to affect the use of the connecting pin 2222. The protection plate 23 can be rotated on the connecting plate 221 to cover the second through hole 5 on the connecting plate 221, so as to prevent dust from entering the main shaft 1 through the second through hole 5 when the barring device 2 is not in use, thereby affecting the service life of the main shaft 1.

[0043] For example, in actual use, the winch device 2 is located on a bearing seat 01 of the crusher. Due to the installation requirements of the winch device 2, the bearing seat 01 is not closed to the end face of the main shaft 1. After the winch work is completed, the fixed plate 2221 is connected to the connecting plate 221 through the connecting bolts 2223. The fixed plate 2221 and the connecting plate 221 are not tightly fitted, resulting in dust entering the second through hole through the gap between the fixed plate 2221 and the connecting plate 221. 5 then falls on the spindle 1, affecting the life of the spindle 1. The protection plate 23 is arranged so that after the turning work is completed and before the fixing plate 2221 is connected to the connecting plate 221, the protection plate 23 can be rotated until it can completely cover the second through hole 5, and then the protection plate 23 is locked to prevent the protection plate 23 from continuing to rotate, ensuring that the second through hole 5 is sealed, and then the fixing plate 2221 is installed on the connecting plate 221 to prevent dust from entering the spindle 1 and extend the service life of the spindle 1.

[0044] Specifically, the protection plate 23 and the connecting plate 221 are rotatably connected by bolts. The protection plate 23 is locked by tightening the bolts, and the protection plate 23 can be rotated on the connecting plate 221 by loosening the bolts.

[0045] In some embodiments, a marking groove 8 is provided on the protective plate 23, and a marking line is provided on the connecting plate 221. When the protective plate 23 is rotated until the marking line is opposite to the marking groove, the third through hole 7 corresponds to the second through hole 5; when the protective plate 23 is rotated until the marking line is misaligned with the marking groove 8, the protective plate 23 covers the second through hole 5.

[0046] In actual use, the protective plate 23 and the connecting plate 221 are relatively large. When the turning operation is performed, in order to align the third through hole 7 with the second through hole 5 and facilitate the passage of the connecting pin 2222, the marking groove 8 and the marking line are provided. When the protective plate 23 is rotated, by observing the correspondence between the marking groove 8 and the marking line, the third through hole 7 can be made to correspond to the second through hole 5 as soon as possible, thereby simplifying the operation process, thereby simplifying the turning operation and improving the turning efficiency.

[0047] In some embodiments, the axis of the connecting plate 221, the power output end 211 and the main shaft 1 coincide. The connecting plate 221, the power output end 211 and the main shaft 1 are arranged correspondingly, and the coincidence of their axis facilitates the transmission of the movement of the power output end 211 to the connecting plate 221 and the main shaft 1, thereby making it easier for the main shaft 1 to be driven to rotate, thereby simplifying the turning work.

[0048] In some embodiments, the bolts of the protective plate 23 pass through the connecting plate 221 and are connected to the end axis of the main shaft 1. The position of the end axis of the main shaft 1 remains unchanged during rotation. Therefore, the connection between the bolts of the protective plate 23 and the end axis of the main shaft 1 is equivalent to fixing the bolts. During use, the bolts can be tightened or loosened on the side of the protective plate 23 away from the main shaft 1 to achieve a fixed connection or a rotational connection between the protective plate 23 and the connecting plate 221.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
