Description

Technical Field

[0002] The trolley 1 of the annealing furnace is provided with multiple wheels on both sides of the bottom, and an I-beam 4 is fixed at the wheel position on both sides in the pit. The I-beam 4 is provided with a track 2 parallel to the extension direction of the I-beam 4, and multiple wheels on each side are on the track 2 on the corresponding side. A rack parallel to the extension direction of the track 2 is fixed in the middle of the bottom end of the trolley 1, and a gear meshing with the rack is provided in the pit. A fixed gear shaft is passed through the middle of the gear and is driven to rotate by a motor set in the pit. The trolley 1 moves along the tracks 2 on both sides under the drive of the motor and enters or moves out of the annealing furnace to transport materials. Among them, the top of the pit is provided with multiple pit covers 3 side by side along the width direction of the trolley 1 at the position where the motor is parked. The tracks 2 on both sides of the pit cover 3 are detachably connected to the I-beam 4 at the corresponding positions, and are called detachable tracks 2. The tracks 2 at other positions of the I-beam 4 are fixed on the I-beam 4 as a whole. Among the multiple wheels on one side of the trolley 1, only one wheel is on the detachable track 2 on the corresponding side. Figure 1 Shown is a schematic structural diagram of the tracks 2 and the pit cover 3 on both sides below the trolley 1.

[0047] In one embodiment, Figure 2-16 As shown, there are two track beams 5 and the front and rear track beams 5 are arranged horizontally along the left and right directions. Two pressure plates 11 are fixed to the top surface of the left part of the track beam 5. The right part of the left pressure plate 11 presses on the left part of the top surface of the lower flange of the I-beam 4 at the right pit cover under the trolley, and the left part of the right pressure plate 11 presses on the right part of the top surface of the lower flange of the I-beam 4. The right end of the track beam 5 is fixed to the right inner wall of the pit; the walking device includes a walking frame 12, and a plurality of walking wheels 13 are provided at the front and rear of the bottom of the walking frame 12. The front plurality of walking wheels 13 are located at the right part of the front track beam 5, and the rear plurality of walking wheels 13 are located at the right part of the rear track beam 5. Figure 2-16 The walking device, the lifting device, the support portion 7 and the clamping portion 9 are used to disassemble and assemble the wheel 10 on the right side of the bottom of the trolley.

[0048] In one embodiment, the lifting device is a lifting screw 14, which is screwed to the middle of the walking frame 12 and the lower end of the lifting screw 14 is below the walking frame 12. The vertical axis of the turntable 6 coincides with the axis of the lifting screw 14. Figure 2-16 In this way, the operator in the pit only needs to manually crank the lower end of the lifting screw 14 to achieve the lifting of the lifting screw 14 relative to the walking frame 12, thereby achieving the lifting of the support portion 7 relative to the walking frame 12.

[0049] In one embodiment, Figure 12As shown, the left part of the clamping part 9 is a pressing handle 901, and a support platform 902 extends horizontally to the right from the lower right end of the clamping part 9. The support platform 902 cooperates with the vertical right side of the clamping part 9 to support the wheel 10. The right side of the clamping part 9 is also provided with a socket 903 for inserting the left end of the center axis of the wheel 10. A vertical clamping plate 904 is fixed at the right end of the support platform 902, and the clamping plate 904 cooperates with the right side of the clamping part 9 to clamp the wheel 10. In this way, the wheel 10 is hoisted onto the supporting platform 902, and the left end of the central axis of the wheel 10 is inserted into the socket 903 on the right side of the clamping part 9, and the left side of the wheel 10 is in contact with the right side of the clamping part 9. The clamping plate 904 is fixed to the right end of the supporting platform 902 so that the right side of the wheel 10 is in contact with the left side of the clamping plate 904. The clamping plate 904 cooperates with the right side of the clamping part 9 to clamp the wheel 10. Then, the clamping part 9 drives the clamped wheel 10 to rotate a certain angle around the vertical axis of the turntable 6 along with the support part 7, and The clamping part 9 rotates clockwise by a certain angle relative to the supporting part 7 through the rotating shaft 8, so that the wheel 10 rotates from the upright position to a right-inclined position close to the right I-beam 4. In this way, in the process of moving the wheel 10 to the left to the top surface of the upper flange of the right I-beam 4 through the walking device, the wheel 10 is rotated to a right-inclined position to avoid the baffle of the right wheel 10 of the trolley, and the setting of the pressing handle 901 facilitates the rotation of the clamping part 9 relative to the supporting part 7, thereby facilitating the angle tilt of the clamped wheel 10.

[0050] In one embodiment, the support portion 7 is provided with a first pin hole 15 arranged horizontally in the front-to-back direction, and the clamping portion 9 is provided with a second pin hole 16 parallel to the first pin hole 15. Figure 2-16 The clamping part 9 is used to drive the clamped wheel 10 to rotate along with the support part 7 around the vertical axis of the turntable 6 to a position close to the right I-beam 4. Figure 12-13 , and the clamping portion 9 is used to drive the clamped wheel 10 to rotate clockwise by a certain angle relative to the support portion 7 through the rotating shaft 8, so that the wheel 10 rotates from the upright position to the rightward inclined position, the axis of the second latch hole 16 coincides with the axis of the first latch hole 15, and the first safety pin is inserted into the second latch hole 16 and the first latch hole 15. Figure 13-14. Preferably, the rotating shaft 8 is located in the upper middle part of the support part 7, and the second latch hole 16 is located on the pressing handle 901. Preferably, the clamping part 9 is used to drive the clamped wheel 10 to rotate 180° along with the support part 7 around the vertical axis of the turntable 6 to a position close to the right I-beam 4, and the clamping part 9 is used to drive the clamped wheel 10 to rotate 45° clockwise relative to the support part 7 through the rotating shaft 8, and the axis of the second latch hole 16 coincides with the axis of the first latch hole 15. In this way, when the clamped wheel 10 is rotated from the upright position to the rightward inclined position close to the right I-beam 4, inserting the first safety pin into the second latch hole 16 and the first latch hole 15 can prevent the clamping part 9 from rotating relative to the support part 7, so that the clamping part 9 and the support part 7 can move to the left as a whole along with the walking device.

[0051] In one embodiment, the support portion 7 is further provided with a third latch hole 17 parallel to the first latch hole 15, and the clamping portion 9 is further provided with a fourth latch hole 18 parallel to the third latch hole 17. Figure 2-16 The lifting device is used to drive the support part 7 to rise, and the clamping part 9 cooperates with the support part 7 to rotate the clamped wheel 10 from the right-tilted position to the upright position. The axis of the fourth latch hole 18 coincides with the axis of the third latch hole 17, and a second safety pin is inserted into the fourth latch hole 18 and the third latch hole 17. Figure 15-16 In this way, when the clamped wheel 10 rotates from the right-tilted position to the upright position, the second safety pin is inserted into the fourth latch hole 18 and the third latch hole 17 to prevent the clamping portion 9 from rotating relative to the support portion 7, so that the clamping portion 9 and the support portion 7 can be lifted up as a whole along with the lifting device, so that the clamped wheel 10 can be lifted to the wheel 10 installation position.

[0052] A method for disassembling a trolley wheel, using the above-mentioned trolley wheel disassembly and assembly tool for disassembly, comprises the following steps:
