Description

Technical Field

[0001] This utility model relates to the field of glass kiln technology, and in particular to a chimney cover brick lifting device and a glass kiln feeding channel. Background Technology

[0002] The feed channel of a glass furnace is the passageway through which molten glass flows. A chimney is located at the top of the feed channel, and the chimney is typically fitted with an openable / closable cover. Opening the cover accelerates the airflow within the feed channel, thus speeding up the cooling of the molten glass; closing the cover insulates the feed channel, reducing heat loss from the molten glass. Therefore, the temperature of the feed channel can be regulated by opening and closing the cover. Because the cover is permanently positioned on the high-temperature chimney, and because the exhaust gases inside the feed channel easily corrode the cover, it needs to be replaced periodically. However, replacing the cover directly on the high-temperature chimney poses a safety hazard. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0023] Reference Figures 1 to 3 As shown, this utility model provides a chimney cover brick lifting device.

[0024] The chimney cover brick lifting device includes a translation mechanism 100, a support 200, a lifting mechanism 300, a clamping mechanism 400, and a cover brick 500.

[0025] Reference Figure 2 As shown, the translation mechanism 100 includes a guide rail 110, a roller 120, and a brake 130.

[0026] The guide rail 110 is installed on the top of the glass furnace feeding channel frame 10. In this embodiment, the guide rail 110 extends in the front-back direction and is provided with a track groove that extends in the front-back direction. The roller 120 is rotatably connected to the bottom of the bracket 200 and rotates around an axis that extends in the left-right direction. The roller 120 is rotatably disposed in the track groove and causes the bracket 200 to move along the guide rail 110.

[0027] The braking component 130 includes a handle 131 and a brake block 132. The handle 131 is rotatably connected to the bottom of the bracket 200. The handle 131 rotates about an axis extending in the vertical direction. The axis of rotation of the handle 131 extends to the height of the roller 120. The brake block 132 is connected to the axis of rotation. When the handle 131 rotates the brake block 132 to the roller 120, the brake block 132 presses against the roller 120, preventing the roller 120 from rotating. This prevents the bracket 200 from moving relative to the guide rail 110, thus fixing the position of the bracket 200.

[0028] In this embodiment, refer to Figure 2As shown, there are at least four rollers 120, and the bracket 200 is provided with two axles. The two axles are distributed at intervals along the front-back direction. Each axle is hinged to a roller 120 at its left and right ends, so that the bracket 200 can move smoothly in the front-back direction. The outer diameter of the roller 120 matches the width of the track groove of the guide rail 110 in the vertical direction, so that the roller 120 can move smoothly in the front-back direction along the track groove.

[0029] In this embodiment, there are at least two brake elements 130. The two brake elements 130 are respectively disposed on the left and right sides of the bracket 200. The two rollers 120 connected to the same axle are braked by the two brake elements 130. By restricting the rotation of a set of rollers 120, the resistance of the bracket 200 moving back and forth along the guide rail 110 is increased, thereby preventing the bracket 200 from moving in the back and forth direction.

[0030] Reference Figure 1 As shown, the bracket 200 includes a base, a horizontal frame, a diagonal frame, a vertical frame, and an adjusting seat. Rollers 120 and brakes 130 are both mounted on the base. The horizontal frame extends in the front-to-back direction and is connected to the base at its bottom. The diagonal frame gradually slopes downward from front to back and is connected to the front end of the horizontal frame at its bottom. The diagonal frame is located above the base. The vertical frame extends in the up-down direction and is connected to the rear end of the horizontal frame at its top. The vertical frame is located behind the base and limits the forward movement of the bracket 200 relative to the guide rail 110. The rear end of the vertical frame is connected to the adjusting seat, which has a guide hole 210 extending in the up-down direction.

[0031] Reference Figure 1 As shown, the lifting mechanism 300 includes a lever 310, an adjusting rod 320 and a turntable 330. The middle part of the lever 310 is hinged to the top of the inclined frame of the bracket 200. When the lever 310 rotates around an axis extending in the left and right direction, the hinge point between the lever 310 and the inclined frame is the fulcrum. The distance from the front end of the lever 310 to the fulcrum is less than the distance from the rear end of the lever 310 to the fulcrum.

[0032] The top of the adjusting rod 320 is provided with a hinge seat, and the hinge seat is provided with a hinge shaft 321 extending in the left and right direction. The rear end of the lever 310 is provided with a slide groove 311, which extends in the front and back direction and passes through the lever 310 in the left and right direction. The hinge shaft 321 is movably disposed in the slide groove 311. The adjusting rod 320 passes downward through the guide hole 210 of the bracket 200 and slides in the up and down direction. The outer side wall of the adjusting rod 320 is provided with an external thread. The diameter of the guide hole 210 is larger than the outer diameter of the external thread of the adjusting rod 320 so that the adjusting rod 320 can slide smoothly up and down along the guide hole 210.

[0033] The turntable 330 is provided with a nut 331, which has a threaded hole that runs through the top and bottom. The threaded hole of the nut 331 is engaged with the external thread of the adjusting rod 320, so the turntable 330 is rotatably connected to the outside of the adjusting rod 320. The turntable 330 is located below the adjusting seat of the bracket 200.

[0034] When the front end of lever 310 is connected to clamping mechanism 400 and cover brick 500, the front end of lever 310 is pulled downward by clamping mechanism 400 and cover brick 500, causing the rear end of lever 310 to move upward. This causes the rear end of lever 310 to drive adjusting rod 320 to move upward, causing turntable 330 to abut against the bottom of adjusting seat of bracket 200. Turntable 330 restricts the degree of freedom of adjusting rod 320 to move upward.

[0035] Rotating the turntable 330 causes the nut 331 to rotate, making the nut 331 rotate relative to the external thread of the adjusting rod 320. This causes the turntable 330 to move upward or downward relative to the adjusting rod 320. Since the top of the turntable 330 remains in contact with the bottom of the adjusting seat of the bracket 200, the turntable 330 changes the length of the adjusting rod 320 above the adjusting seat of the bracket 200, which changes the height of the rear end of the lever 310. This causes the front end of the lever 310 to move, causing the clamping mechanism 400 and the cover brick 500 to move upward or downward.

[0036] During the rotation of lever 310, since adjusting rod 320 is confined in guide hole 210 and hinge shaft 321 at the top of adjusting rod 320 moves in slide groove 311, adjusting rod 320 can avoid interfering with the rotation of lever 310.

[0037] By moving the adjusting rod 320 up and down, the lever 310 drives the clamping mechanism 400 and the cover brick 500 to move, which helps to save the pulling force required to lift the cover brick 500, and the personnel operating the adjusting rod 320 can stay away from the chimney, thus improving safety.

[0038] In this embodiment, the adjustment rod 320 is moved up and down by rotating the turntable 330 relative to the adjustment rod 320, eliminating the need for the operator to constantly pull the adjustment rod 320, thus saving the operator effort. Meanwhile, the turntable 330 is always in contact with the bottom of the adjustment seat, which can prevent the adjustment rod 320 from coming loose upwards and eliminate safety hazards.

[0039] Reference Figure 1 As shown, in this embodiment, the lever arm of the hinge seat of the adjusting rod 320 and the lever 310 is greater than the lever arm of the clamping mechanism 400 on the lever 310. This helps to reduce the pulling force required for the adjusting rod 320 to lift the clamping mechanism 400 through the lever 310, thereby reducing the pressure between the nut 331 and the external thread of the adjusting rod 320, and making the turntable 330 rotate more effortlessly.

[0040] Reference Figure 1and Figure 3 As shown, the clamping mechanism 400 includes a lifting rod 410 and a gripper 420. The top end of the lifting rod 410 is hinged to the front end of the lever 310, and the bottom end of the lifting rod 410 is hinged to the top of the gripper 420. The bottom of the gripper 420 is provided with a clamping groove 421 that runs through the front-back direction. The width of the clamping groove 421 in the left-right direction gradually decreases from top to bottom.

[0041] A clamping block 510 is provided on the top of the cover brick 500. The width of the clamping block 510 gradually decreases from top to bottom in the left and right directions. The clamping block 510 is inserted into the clamping groove 421 in the front and back directions, so that the cover brick 500 is clamped to the bottom of the clamping claw 420, so that the clamping mechanism 400 can drive the cover brick 500 to move. The bottom of the cover brick 500 extends out from under the clamping claw 420, so that the bottom surface of the cover brick 500 covers the top of the chimney.

[0042] Since the width of both the clamping block 510 and the clamping groove 421 gradually decreases from top to bottom, after the clamping block 510 is placed into the clamping groove 421, the weight of the cover brick 500 causes it to slide down along the clamping groove 421 to fix its position, so as to facilitate the replacement of the cover brick 500.

[0043] The lifting mechanism 300 drives the clamping mechanism 400 to move upward, causing the cover brick 500 to leave the chimney. Then, the translation mechanism 100 drives the support 200 to move, causing the clamping mechanism 400 to move the cover brick 500 in the front-back direction, thus displacing the cover brick 500 from the chimney. The cover brick 500 is then replaced on the clamping mechanism 400, avoiding replacement of the cover brick 500 above the chimney, making the replacement of the cover brick 500 safer, and enabling rapid maintenance, installation, and replacement of the cover brick 500, reducing the labor intensity of on-site personnel.

[0044] This utility model also provides a glass kiln feeding channel, including a chimney and a chimney cover lifting device as described in the above embodiments, wherein the cover bricks are detachably and detachably placed on the top of the chimney.

[0045] Since the glass kiln feeding channel adopts all the technical solutions of the chimney cover brick lifting device of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
