Description

Technical Field

[0001] This utility model relates to the technical field of cone crusher equipment, specifically to a magnetic adsorption mounting structure for the hydraulic cylinder of a cone crusher main unit. Background Technology

[0002] Existing cone crushers mainly include floating bowl-shaped cone crushers, spiral cone crushers, and floating head cone crushers. The main cone housing of a floating bowl-shaped cone crusher mainly consists of a main frame and an upper housing mounted on the main frame. The hydraulic cylinder is hinged to the main frame and the upper housing via a pin. The upper housing can be raised and lowered on the main frame via the hydraulic cylinder. To ensure the stable installation of the pin and to avoid accidental damage to the hydraulic cylinder when disassembling it and striking the pin between the hydraulic cylinder and the main frame, flat washers are usually fitted on both sides of the pin. Limiting pins are inserted on both sides of the pin to limit the flat washers. However, in actual production, it has been found that the equipment continuously vibrates during the cone crusher's crushing process. Since the flat washers are movably fitted on the pins, the vibration of the cone crusher causes the flat washers to continuously shake and collide with the hydraulic cylinder, generating significant noise. In view of this, this problem has been studied, hence this case. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a magnetic adsorption installation structure for the hydraulic cylinder of a cone crusher, which, through the setting of a magnetic adsorption mechanism, allows the flat washer to be directly and stably adsorbed on the outer surface of the hinge seat after being sleeved on the pin, thereby ensuring that the flat washer will not shake when the cone crusher vibrates, thus preventing the flat washer from colliding with the hinge seat or other components and effectively avoiding the generation of collision noise of the flat washer.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a magnetic adsorption mounting structure for a hydraulic cylinder of a cone crusher, including a hydraulic cylinder and a main frame, wherein the hinge seat at the bottom of the hydraulic cylinder is hinged to the hinge plate on the main frame by a pin, both ends of the pin are fitted with flat washers, and both ends of the pin are detachably inserted with limiting pins on the outside of the flat washers, and the flat washers are detachably adsorbed and connected to the outer surface of the hinge seat by a magnetic adsorption mechanism.

[0005] Furthermore, the magnetic adsorption mechanism includes at least one magnet, with the magnet fixedly disposed on at least one of the flat washer and the hinge seat.

[0006] Furthermore, the magnet is placed on the flat washer, and the hinge base is made of a magnetically attractive material.

[0007] Furthermore, the magnet is cylindrical, and the flat washer has mounting holes that match the magnet, with the magnet embedded in the mounting holes.

[0008] Furthermore, the mounting holes penetrate both sides of the flat washer.

[0009] Furthermore, the number of magnets is 3-5, and they are evenly spaced along the circumference of the flat washer.

[0010] Furthermore, the magnet is ring-shaped and is coaxially arranged with the flat washer.

[0011] Furthermore, the magnet is located on the hinge seat, and the flat washer is made of a magnetically attractive material.

[0012] Furthermore, both the flat washer and the hinge seat are equipped with magnets, and the magnets on the flat washer and the hinge seat are arranged to attract each other.

[0013] Furthermore, the magnet is a neodymium iron boron magnet.

[0014] As described above, the magnetic adsorption mounting structure for the hydraulic cylinder of a cone crusher provided by this utility model has the following beneficial effects: With the magnetic adsorption mechanism, when the flat washer is fitted onto the pin, it can be directly and stably adsorbed onto the outer surface of the hinge seat, thus making the two stably connected as a whole. Simultaneously, its installation on the pin is simple, and it is easy to easily and quickly remove the flat washer from the pin. When the cone crusher continuously vibrates during the crushing process, the flat washer is stably adsorbed onto the hinge seat, restricting the degree of freedom of movement of the flat washer. There is no wobbling gap between the two, thus ensuring that the flat washer will not wobble when the cone crusher vibrates. This prevents the flat washer from colliding with the hinge seat or other components, effectively avoiding the generation of collision noise from the flat washer. Attached Figure Description

[0019] The present invention will be further described below through specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 3 As shown, the present invention provides a magnetic adsorption mounting structure for a hydraulic cylinder of a cone crusher, comprising a hydraulic cylinder 1 and a main frame 2. The hinge seat 11 at the bottom of the hydraulic cylinder 1 is hinged to the hinge plate 21 on the main frame 2 via a pin 3. Flat washers 4 are fitted on both ends of the pin 3. Limiting pins are detachably inserted at both ends of the pin 3 on the outside of the flat washers 4. The flat washers 4 are detachably adsorbed and connected to the outer surface of the hinge seat 11 via a magnetic adsorption mechanism 5.

[0022] With the magnetic adsorption mechanism 5, the flat washer 4 can be directly and stably adsorbed on the outer surface of the hinge seat 11 after being sleeved on the pin 3, thus making the two stably connected as a whole. At the same time, its installation on the pin 3 is also simple, and it is also convenient to easily and quickly remove the flat washer 4 from the pin 3. When the cone crusher continuously vibrates during the production crushing process, the flat washer 4 is stably adsorbed on the hinge seat 11, which restricts the degree of freedom of the flat washer 4. There is no wobbling gap between the two, thus ensuring that the flat washer 4 will not shake when the cone crusher vibrates. This prevents the flat washer 4 from colliding with the hinge seat 11 or other components, effectively avoiding the generation of collision noise from the flat washer 4.

[0023] Correspondingly, the magnetic adsorption mechanism 5 includes at least one magnet 51. The magnet 51 is fixedly provided on at least one of the flat washer 4 and the hinge seat 11. Preferably, the number of magnets 51 is 3-5 and they are evenly spaced along the circumference of the flat washer 4. In this way, the uniformity and stability of the magnetic adsorption between the flat washer 4 and the hinge seat 11 are effectively ensured.

[0024] The magnet 51 is disposed on the flat washer 4, and the hinge seat 11 is made of a magnetically attractive material, such as iron or carbon steel.

[0025] Preferably, the magnet 51 is cylindrical, such as cylindrical or polygonal, and the flat washer 4 is provided with a mounting hole 41 that matches the magnet 51. The magnet 51 is embedded in the mounting hole 41, and the mounting hole 41 penetrates both sides of the flat washer 4. Thus, the thickness of the magnet 51 is consistent with the thickness of the flat washer 4, so as to further ensure the magnetic force of the magnet 51.

[0026] Preferably, the magnet 51 is a neodymium iron boron magnet 51, which is a permanent magnet material with strong magnetic properties. Its performance is far superior to that of traditional magnets 51, and it has a smaller volume under the same magnetic force.

[0027] In addition, a protective cover 6 is installed on the hinge seat 11 by locking screws 7.

[0028] In another embodiment, preferably, the magnet 51 is in the shape of a ring, and the magnet 51 is coaxially arranged with the flat washer 4.

[0029] Example 2

[0030] The difference between this embodiment and embodiment one is that the magnet 51 is disposed on the hinge seat 11, and the flat washer 4 is made of a magnetically attractive material, such as iron or carbon steel.

[0031] Other technical features are the same as in Embodiment 1.

[0032] Example 3

[0033] The difference between this embodiment and embodiment one is that: both the flat washer 4 and the hinge seat 11 are provided with magnets 51, and the magnets 51 on the flat washer 4 and the magnets 51 on the hinge seat 11 are mutually attracted.

[0034] Other technical features are the same as in Embodiment 1.

[0035] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
