Description

Technical Field

[0001] The utility model belongs to the field of ore dressing technology and mechanical processing, and relates to a motor quick disassembly and assembly device for a multi-cylinder cone crusher. Background Art

[0002] Multi-cylinder cone crushers are widely used in mining enterprises and are indispensable ore crushing equipment for mining enterprises. The mining crushing process is a three-stage one closed circuit + coarse particle dry separation process. After coarse crushing, the underground ore is lifted to the skip bin and enters the secondary crushing by the ore feeding electric vibration and belt. The secondary crushing uses a cone crusher, and the crushed products are transported to the screening plant by belts for screening. The above-screen products enter the dry separation and discard, the dry separation waste stone enters the stone processing plant, and the dry separation concentrate enters the fine crushing for further particle size crushing. The fine crusher uses a cone crusher, and the fine crushing products return to the screening to form a closed circuit. The under-screen products are crushed and qualified, and are transported to the grinding and floating powder ore bin by belts for subsequent grinding and separation operations. The crusher is a multi-cylinder hydraulic cone crusher consisting of 6 iron-passing release hydraulic cylinders and 12 locking hydraulic cylinders. Its main structures include horizontal shaft, large and small bevel gears, main shaft, eccentric sleeve, spherical tile frame, spherical tile, moving cone assembly, fixed cone assembly, adjustment ring, main frame, etc. It has a simple and compact structure. Iron-passing protection and adjustment of the discharge port are completed through the hydraulic system.

[0003] In the mining industry, the secondary and secondary crushing is arranged as one medium and two fine crushing. There is only one medium crusher without a backup. Once a failure occurs, the main production will be affected. In many companies, there is no backup system for secondary crushing. At this time, if the crusher motor or other failures occur, it will take a lot of time to recover, and the repair time is particularly critical.

[0004] At present, the replacement of the motor of the crusher in the medium crushing process is mainly carried out in the following ways: CN202520889U-A motor belt adjustment device, which uses the rotation of the thread to drive the motor base and the motor to move synchronously. However, it is only suitable for small motors, not large motors. The reason is: large motors are relatively heavy. For example, the weight of the HP500 crusher motor is 3690kg, and the motor base is about 300kg. It is very laborious and inefficient to use the rotation of the thread to drive the motor base and the motor; and it becomes more and more difficult to operate as the use time increases. Empirical statistics: It takes more than an hour to dismantle using thread operation (the time required for the installation process is doubled). With continuous use, the thread wears and the influence of dust, and the time required is getting longer and longer (the dust on the crusher site itself is relatively serious, and dust on the thread is inevitable). Utility Model Content

[0005] The utility model provides a motor quick disassembly and assembly device for a multi-cylinder cone crusher, which can realize quick replacement of the crusher motor, reduce maintenance time and improve the working efficiency of the crusher.

[0006] In order to achieve the above technical purpose, the technical solution adopted in this application is: a motor quick disassembly and assembly device for a multi-cylinder cone crusher, comprising:

[0007] The motor base adjustment slide rail is installed along the path of the motor installation direction and the disassembly direction;

[0008] A motor mounting base is mounted on the motor base adjusting slide rail and slides along the motor base adjusting slide rail under the action of an external force;

[0009] A hydraulic cylinder connected to a side surface of the motor mounting base;

[0010] Wherein, when the piston rod of the hydraulic cylinder is extended and retracted, it can drive the motor mounting base to slide along the motor base adjustment slide rail; the hydraulic cylinder is installed on the main frame of the multi-cylinder cone crusher.

[0011] As an improved technical solution of the present application, the motor is fixed to the motor mounting base by bolts.

[0012] As an improved technical solution of the present application, the motor base adjusts the length of the slide rail so that the motor mounting base can reach two positions during the sliding process, the first position being the position of the motor's normal working station, and the second position being the position of the motor's V-belt disassembly station.

[0013] As an improved technical solution of the present application, the motor mounting base is mounted on the motor base adjusting rail by bolts.

[0014] As an improved technical solution of the present application, there are two hydraulic cylinders, which are respectively arranged on both sides of the motor mounting base, and the action direction of the hydraulic cylinders is perpendicular to the motor drive shaft.

[0015] As an improved technical solution of the present application, the hydraulic cylinder is connected to the motor mounting base through a hydraulic cylinder connecting device; the hydraulic cylinder connecting device is a piston rod mounting seat arranged on the side of the motor mounting base, the piston rod mounting seat includes a mounting groove, and a group of through holes are symmetrically arranged on both sides of the mounting groove; the end of the piston rod of the hydraulic cylinder is provided with a through hole, and the axis of the through hole is perpendicular to the axis of the piston rod; the piston rod of the hydraulic cylinder is installed in the mounting groove, and the relative fixation of the piston rod of the hydraulic cylinder and the piston rod mounting seat is achieved by bolting the through hole on the end of the piston rod of the hydraulic cylinder and a group of through holes on the mounting groove.

[0016] Beneficial Effects

[0017] The device of the present application transforms the motor base and no longer uses traditional threads to slowly loosen. Instead, it uses a hydraulic station drive, which can achieve rapid disassembly and assembly, simple and convenient operation, and greatly saves assembly time and maintenance downtime.

[0018] The biggest advantages of hydraulic drive adjustment device over threaded rotary transmission should be three: first, hydraulic device is not affected by the on-site environment. For example, dust adhesion and flushing slurry adhesion will affect the next operation of the thread, while hydraulic device is not affected by them; second, hydraulic device is easy to operate, fast in action, and saves time; third, hydraulic device is more practical for large motors, and threaded transmission is suitable for small motors.

DETAILED DESCRIPTION

[0024] In order to facilitate those skilled in the art to better understand the technical solution of the present application, a clear and complete description of the technical solution of the present application is given below in conjunction with the accompanying drawings.

[0025] definition:

[0026] The re-tightening shaft is a shaft whose function is to push the motor mounting base under the action of the jack to achieve re-tightening of the V-belt.

[0027] "Forward" is the direction for removing the motor V-belt; "backward" is the direction for installing the motor V-belt; "forward" and "backward" are relative nouns.

[0028] The "one side of the baffle" in "the mechanical jack is arranged on one side of the baffle and acts on the baffle" refers to the side where the mechanical jack can push the motor mounting base to slide and re-tighten the V-belt, specifically the opposite side of the hydraulic cylinder installation position.

[0029] The “two sides” in “two hydraulic cylinders are respectively arranged on both sides of the motor mounting base” refers to the sides where the two ends of the motor's transmission shaft are located.

[0030] like Figure 1 As shown, the existing crusher uses a manual loosening device, which is extremely inconvenient to operate. Especially after being used for a period of time, dust adheres to the surface of the threaded device, making it extremely difficult to operate, time-consuming and labor-intensive, and there are serious safety hazards in the operation.

[0031] like Figure 2-3 As shown, the present application is modified to add a hydraulic device; after the device is put into use, the effect is obvious and the operation is quick, which solves all the disadvantages brought by the threaded transmission. According to statistics, this modification can reduce the operation time here by more than 2 hours.

[0032] like Figure 2-4 As shown, a motor quick disassembly and assembly device for a multi-cylinder cone crusher comprises:

[0033] The motor base adjusting slide rail 5 is installed along a path where the installation direction and the disassembly direction of the motor 1 (crusher motor) are located; that is, the motor base adjusting slide rail 5 controls the installation and disassembly of the motor 1 .

[0034] Among them, the length of the motor base adjustment rail 5 is long enough, and at least the length of the motor base adjustment rail 5 is required so that the motor mounting base 3 can reach two positions during the sliding process, the first position is the position of the normal working station of the motor 1, and the second position is the position of the V-belt disassembly station of the motor 1.

[0035] The motor mounting base 3 is mounted on the motor base adjusting slide rail 5 and slides along the motor base adjusting slide rail 5 under the action of external force. In order to facilitate disassembly, the motor 1 is fixed to the motor mounting base 3 by bolts; the motor mounting base 3 is mounted on the motor base adjusting slide rail 5 by bolts.

[0036] The hydraulic cylinder 10 is connected to one side of the motor mounting base 3; in order to ensure the sliding stability of the motor mounting base 3, there are two hydraulic cylinders 10, which are arranged on both sides of the motor mounting base 3, and the action direction of the hydraulic cylinder 10 is perpendicular to the motor drive shaft. Specifically, the hydraulic cylinder 10 is connected to the motor mounting base 3 through a hydraulic cylinder connecting device; the hydraulic cylinder connecting device is a piston rod mounting seat 13 arranged on the side of the motor mounting base, and the piston rod mounting seat 13 includes a mounting groove, and a group of through holes are symmetrically arranged on both sides of the mounting groove; the end of the piston rod of the hydraulic cylinder is provided with a through hole, and the axis of the through hole is perpendicular to the axis of the piston rod; the piston rod of the hydraulic cylinder is installed in the mounting groove, and the relative fixation of the piston rod of the hydraulic cylinder and the piston rod mounting seat 13 is achieved by bolting the through hole on the end of the piston rod of the hydraulic cylinder and a group of through holes on the mounting groove. Specifically: the tail of the hydraulic cylinder 10 is fixed on the main frame 6, and the telescopic side of the piston rod of the hydraulic cylinder is connected to the motor mounting base 3 through the hydraulic cylinder connecting device 8; the hydraulic cylinder connecting device 8 is arranged on the piston rod mounting seats on the two sides of the motor mounting base 3; the piston rod mounting seat 13 is provided with a through hole, and the end of the piston rod of the hydraulic cylinder passes through the through hole. When operation is required, the fixing bolts of the motor base adjustment slide rail 5 are loosened, and the piston rod of the hydraulic cylinder is extended and retracted. Because the tail of the hydraulic cylinder 10 is fixed on the main frame 6 and cannot move, the piston rod of the hydraulic cylinder can drive the motor mounting base 3 to slide along the motor base adjustment slide rail 5.

[0037] When the piston rod of the hydraulic cylinder 10 is extended or retracted, it can drive the motor mounting base 3 to slide along the motor base adjusting slide rail 5; the hydraulic cylinder 10 is installed on the main frame of the multi-cylinder cone crusher.

[0038] In order to ensure that the tightness of the V-belt meets the requirements of the crusher specifications, a re-tightening device is also included, and the re-tightening device includes a re-tightening shaft and a mechanical jack; the re-tightening shaft 7 is located below the motor mounting base 3 and passes through the motor mounting base 3; at the same time, the re-tightening shaft 7 is perpendicular to the motor drive shaft; the re-tightening shaft 7 is provided with a baffle on the opposite side of the hydraulic cylinder 10, and the mechanical jack is provided on the baffle side and acts on the baffle. It should be noted that this re-tightening device does not have to be used. Considering that the hydraulic system pressure will have poor sealing with subsequent use, when the pressure does not meet the requirements, the tightness of the V-belt will not meet the requirements. At this time, the mechanical jack can be used to further push the motor base to further tighten the V-belt. When the crusher is in operation, the hydraulic system is maintained.

[0039] The technology of this application is further explained below in conjunction with specific implementation plans.

[0040] like Figure 2-4 As shown, a motor quick disassembly and assembly device for a multi-cylinder cone crusher replaces the original motor base (such as Figure 1 As shown), add a hydraulic drive device.

[0041] A motor quick disassembly and assembly device for a multi-cylinder cone crusher mainly includes the following components:

[0042] 1. Motor mounting base 3: including motor fixing bolt hole 4, motor base adjustment slide rail 5 fixing bolt hole, hydraulic cylinder connection device 8 and hydraulic cylinder fixing device 9. Motor 1 is fixed to motor mounting base 3 by passing bolts through motor fixing bolt hole 4; motor mounting base 3 is fixed to motor base adjustment slide rail 5 by passing bolts through motor base adjustment slide rail fixing bolt hole. Hydraulic cylinder connection device 8 is arranged on both sides of motor mounting base 3, which is one of the most important components of the processing of motor mounting base 3, and its purpose is to be fixedly connected with the extended end of the piston rod of hydraulic cylinder 10. Motor 1 is fixed to motor mounting base 3 by bolts, and motor mounting base 3 is fixed to motor base adjustment slide rail 5 by bolts.

[0043] 2. Hydraulic cylinder fixing device: used to fix the hydraulic cylinder 10, which is fixed to the crusher main frame 6 by bolts.

[0044] 3. Hydraulic cylinder device: Use bolts to fix the cylinder body of the hydraulic cylinder 10 on the hydraulic cylinder fixing device 9.

[0045] 4. Hydraulic station system: This device provides power for the hydraulic cylinder device, and is equipped with oil supply motor (hydraulic oil station 11), electromagnetic reversing valve, oil pipe 12 and other components.

[0046] 5. Re-tightening device: This device is used to restore the crushing motor. The purpose is to further tighten the V-belt when the motor 1 is finally fixed to meet the V-belt tension required by the crusher. Its main purpose is to prevent the V-belt from being fully pulled into place by the motor pulley 2 when the hydraulic cylinder 10 pulls the motor 1 and the motor mounting base 3, so as to play a re-tightening role. This device needs to be determined according to the on-site conditions. It will not be used under normal circumstances and serves as a safety device.

[0047] The operating logic of the motor quick disassembly and assembly device of the present application is as follows:

[0048] When the crusher is operating normally, the motor quick disassembly and assembly device is idle and only requires regular inspection and maintenance.

[0049] When the crusher fails, it needs to remove the V-belt, replace the motor 1, adjust the horizontal shaft side clearance and other corresponding procedures, and this device will be used. The specific disassembly and assembly operations are as follows:

[0050] 1. Motor dismantling process:

[0051] Step 1: Use a wrench to loosen the fixing bolts of the motor base adjustment rail 5;

[0052] Step 2: Start the hydraulic station and use the electromagnetic reversing valve to inject oil into the hydraulic cylinder 10. At this time, the piston rod of the hydraulic cylinder moves forward, pushing the motor mounting base 3 to move forward along the motor base adjustment slide rail 5. The motor 1 moves with the motor mounting base 3 until it reaches the position where the V-belt can be removed.

[0053] Step 3: If you need to repair or replace the motor, just remove the motor fixing bolts. If you do not need to deal with motor 1, proceed to step 2.

[0054] 2. Installation process:

[0055] After the equipment failure is eliminated, the V-belts and other parts will be restored and installed, as follows:

[0056] Step 1: Install the V-belt on the motor pulley and the horizontal shaft pulley;

[0057] Step 2: Start the hydraulic station and use the electromagnetic reversing valve to reversely inject oil into the hydraulic cylinder 10. At this time, the piston rod contracts inward, pulling the motor 1 to move backward until it reaches the position where the V-belt is tightened.

[0058] Step 3: Use the re-tightening device to push the crusher motor (in the same direction as the reverse oil injection of the hydraulic cylinder, the piston rod contracts inwards, and pulls the motor backwards), and further tighten the V-belt to meet the V-belt tension required by the crusher. This step is not necessary.

[0059] Step 4: Use a wrench to tighten the motor base adjustment rail fixing bolts.

[0060] Therefore, the motor base adjusts the length of the slide rail 5 so that the motor mounting base 3 can reach two positions during the sliding process, the first position is the position of the normal working position of the motor 1, and the second position is the position of the V-belt removal position of the motor 1. The hydraulic cylinder 10 has not only a pushing function, but also a pulling function. It can be understood that when the motor 1 needs to be repaired, the hydraulic cylinder 10 pushes forward and the motor 1 reaches the position of removing the V-belt; after the repair, the hydraulic cylinder 10 pulls backward and the motor 1 reaches the normal use position.

[0061] Compared with the prior art, the motor quick disassembly and assembly device of the present application has the following advantages:

[0062] 1. The device changes the original clumsy operation method and now the operation is simpler.

[0063] 2. Due to the change in method, a lot of time was saved, which gained valuable time for resuming production.

[0064] 3. The device is operated by a hydraulic device, and there is no need for personnel to use crowbars, sledgehammers, etc. to move the motor little by little, thus completely avoiding the safety hazards here.

[0065] 4. Since the transformation and use, the effect has been very stable, creating immeasurable value for the enterprise.

[0066] In summary, the device of the present application changes the original clumsy operation method, and the operation is now simpler. Due to the change of the method, a lot of time is saved, and precious time is gained for resuming production.

[0067] The device of this application uses a hydraulic device to operate, and there is no need for personnel to use crowbars, sledgehammers, etc. to help the threaded operation move the motor little by little, completely avoiding the safety hazards here. Since the modification and use, the effect of use has been very stable, creating immeasurable value for the company. At the same time, the effect and purpose of the device modification of this application is to avoid the safety risks brought by the operation and win precious time when failure occurs, creating benefits for the company.
