Description

Technical Field

[0001] This utility model belongs to the field of coking technology, and in particular relates to a spiral adjustment seat device. Background Technology

[0002] Vibratory feeders are crucial power equipment in dry quenching coke production. During installation and commissioning, to ensure sufficient clearance from surrounding fixed equipment and to maintain the equipment's processing capacity, the height and trough inclination angle need to be adjusted. Traditional adjusting seats use an internal and external thread structure, with the external thread fixed and the height adjusted by the internal thread. However, this threaded adjusting seat has several drawbacks: 1. The threads are exposed to air, making them prone to rust and jamming over time. Applying lubricant can attract dust, also causing jamming; 2. Each adjustment requires hoisting or supporting the vibratory feeder, removing it from the adjusting seat before the internal thread can be rotated, which is cumbersome; 3. The thread pitch of the adjusting seat is small, resulting in slow height adjustment and low efficiency; 4. To prevent reverse rotation during vibration, a stop plate needs to be welded to the threaded adjusting seat, but this needs to be cut off for subsequent adjustments, which is inconvenient.

[0025] like Figure 1 As shown, a spiral adjusting seat device 300 is installed at the lower part of the vibration source 100 and the material trough 400. A support spring 200 is installed between the spiral adjusting seat device 300 and the vibration source 100 and the material trough 400, and the support spring 200 plays a role in shock absorption. Furthermore, the spiral adjusting seat device 300 is located on the lower left side of the vibration source 100 and the lower right side of the material trough 400. The two spiral adjusting seat devices 300 maintain a large span to stabilize the equipment. The height of one end of the vibration source 100 and the material trough 400 is adjusted by the spiral adjusting seat device 300, and the change in the height of the vibration source 100 and the material trough 400 adjusts the tilt angle of the material trough 400. Example 1

[0026] like Figure 2 , 3As shown in Figure 4, a spiral adjustment seat device 300 includes a pin 301, a main frame 302, a top cover 303, a screw 304, a lifting sleeve 305, a copper nut 306, a base 307, a thrust ball bearing 308, a bushing 309, and a locking nut 310. The inner cavity of the main frame 302 is configured as a hollow stepped structure. The lower end of the large step of the main frame 302 is fixedly connected to the base 307, forming a sealed space to prevent dust, water, etc. from entering and causing corrosion of the rotating parts, thus preventing them from jamming and becoming unadjustable. A circular lifting sleeve 305 that can move up and down is fitted into the inner hole of the small step on the upper part of the main frame 302. The lifting sleeve 305 is configured as a hollow structure. A copper nut 306 is installed and fixed on the inner wall of the lower section of the lifting sleeve 305, and an internal thread structure is provided on the inner wall of the copper nut 306. Furthermore, a screw 304 is installed inside the lifting sleeve 305. The outer surface of the upper section of the screw 304 is provided with an external thread structure that matches the internal thread of the copper nut 306. Through the rotational movement of the copper nut 306 and the screw 304 in the threaded engagement, the lifting sleeve 305 is driven to move vertically up and down within the main frame 302. Furthermore, an external thread structure for fixed connection is provided on the outer surface of the upper section of the lifting sleeve 305.

[0027] The top cover 303 is installed on the upper end of the lifting sleeve 305. A concave internal thread structure is provided at the center of the lower end of the top cover 303. This internal thread structure is adapted to the external thread structure of the upper section of the lifting sleeve 305. The top cover 303 is fixed by screwing in the external thread of the upper section of the lifting sleeve 305 and the internal thread of the lower end of the top cover 303. The top cover 303 moves vertically up and down with the lifting sleeve 305. Furthermore, the lifting of the top cover 303 is adjusted by the support spring to adjust the height of the vibration source 100 and the height of the material trough 400, thereby further changing the inclination angle of the material trough 400.

[0028] Furthermore, the lower section of the lifting sleeve 305 is provided with a raised step structure on its outer surface. The outer diameter of the step is larger than the outer diameter of the upper section of the sleeve, which serves to limit the upward movement of the lifting sleeve 305 and prevent the lifting sleeve 305 from falling off the main frame 302 during the upward movement.

[0029] Furthermore, the lifting sleeve 305 is provided with a height scale on its side to display the lifting height of the lifting sleeve 305.

[0030] Furthermore, the pin 301 is installed in a horizontal through hole on the lower left side of the main frame 302. A bushing 309 is provided between the pin 301 and the main frame 302. The bushing 309 improves the fitting accuracy and wear resistance. The left end of the pin 301 is hexagonal and can be rotated with a wrench. The right end of the pin 301 is provided with a small bevel gear structure for transmission.

[0031] Furthermore, a large bevel gear structure is provided at the lower end of the screw 304. The large bevel gear of the screw 304 is adapted to mesh with the small gear of the pin shaft 301. Through the rotational meshing of the small bevel gear at the right end of the pin shaft 301 and the large bevel gear at the lower end of the screw 304, the external thread of the upper section of the screw 304 rotates with the thread of the copper nut 306 inside the lifting sleeve 305, converting the rotational motion of the horizontal pin shaft 301 into the vertical up-and-down movement of the lifting sleeve 305, thus playing the role of motion conversion.

[0032] Furthermore, the small bevel gear of the pin shaft 301 and the large bevel gear of the screw 304 are configured with a certain speed ratio, which is equal to the number of teeth of the small bevel gear / the number of teeth of the large bevel gear, thus playing an adjustment role.

[0033] Furthermore, the internal threads of the screw 304 and the copper nut 306 are set as T-type threads, which play a role in transmitting large torque; the number of rotations of the pin 301 and the lifting height of the lifting sleeve 305 can be determined by the speed ratio of the small bevel gear and the large bevel gear and the pitch of the T-type thread; furthermore, the height scale value is marked on the side of the lifting sleeve 305, which clearly and intuitively indicates the lifting height.

[0034] Furthermore, the right end of the hexagonal structure of the pin 301 is provided with an external thread structure, and a matching locking nut 310 is installed thereon. The locking nut 310 locks the rotation of the pin 301, preventing the vibration during the vibratory feeding operation from causing the large bevel gear and the small bevel gear to reverse.

[0035] Furthermore, the inner wall of the thrust ball bearing 308 is installed on the lower outer diameter of the screw 304, and the outer wall is fitted into the recessed step in the center of the base 307, which serves to axially position the screw 304 and reduce friction during rotation.

[0036] Working state: When the material trough 400 needs to be adjusted, the hexagonal pin 301 installed on the left side of the main frame 302 is rotated using a wrench. The small bevel gear at the right end of the pin 301 will rotate simultaneously with the pin 301. The small bevel gear drives the large bevel gear at the lower end of the screw 304 to rotate, which in turn drives the screw 304 to rotate. The copper nut 306 will also rotate with the rotation of the screw 304, causing the external lifting sleeve 305 and the upper top cover 303 to move up and down within the track of the main frame 302. The shoulder on the outer side of the lower end of the lifting sleeve 305 can limit the height of the lifting sleeve and prevent the lifting sleeve 305 from falling off. The top cover 303 fixed to the upper part of the lifting sleeve will adjust the height of the vibration source 100 and the tilt angle of the material trough 400 through the support spring.

[0037] Furthermore, by using the gear ratio of the small bevel gear of pin 301 and the large bevel gear of screw 304, and the pitch of the T-type thread fit between screw 304 and copper nut 306, the relationship between the number of rotations of pin 301 and the lifting distance of lifting sleeve 305 can be easily obtained. Scales can be made on the side of lifting sleeve 305 to easily know the lifting height.

[0038] Furthermore, to prevent the vibration of the vibratory feeder from causing the large bevel gear of the screw 304 and the small bevel gear of the pin 3011 to reverse, a locking nut 310 is installed on the pin 301. After adjusting the height, the locking nut 310 is tightened to lock the pin 301 and prevent reverse rotation. Example 2

[0039] like Figure 5 As shown, a spiral adjustment seat device 300 includes a lifting sleeve 305, a top cover 303, a bushing 309, a ratchet 312, and a cotter pin 311. The lower center of the top cover 303 is provided with a concave step adapted to fit the upper end of the lifting sleeve 305. The center of the concave step of the top cover 303 is provided with a countersunk hole structure, which is matched with a countersunk screw 313. The lifting sleeve 305 is provided with a blind hole structure, and a threaded hole matching the external thread of the countersunk screw 313 is provided at its upper end. The top cover 303 is fixed by the cooperation of the external thread of the countersunk screw 313 and the internal thread of the lifting sleeve 305.

[0040] Furthermore, the ratchet 312 is mounted on the hexagonal left end of the pin 301, and the pin 301 rotates as the ratchet 312 rotates.

[0041] Furthermore, the right end of the pin 301 is provided with a radial through hole that matches the outer diameter of the cotter pin 311, so that the cotter pin 311 can be installed.

[0042] Furthermore, the horizontal through hole on the left side of the main frame 302 is provided with a radial through hole that is adapted to the radial through hole of the pin 301, and the cotter pin 311 is installed in the radial through hole.

[0043] Furthermore, the bushing is provided with a radial through hole that is adapted to the pin 301 and the main frame 302; by inserting the cotter pin 311 into the radial through hole of the main frame 302, the pin 301 and the bushing 309, the pin 301 can be locked to prevent the pin 301 from reversing. Example 3

[0044] like Figure 6As shown, a spiral adjustment seat device 300 has a vibration damping structure between the main frame 302 and the top cover 303, including a support column 314 and a spring 315. The support column 314 is vertically fixed on both sides of the lower end face of the top cover 303, and the lower end of the support column 314 is inserted into the cavity of the main frame 302. Furthermore, between the main frame 302 and the top cover 303, a spring 315 is sleeved on the outer surface of the support column 305 to dampen and balance the vibration of the top cover 303.
