Description

Technical Field

[0001] This invention relates to the field of manual winch technology, specifically to a manual winch device for glass kilns and its application method. Background Technology

[0002] A glass furnace is a thermal equipment used in the glass manufacturing industry to melt glass batches. It melts and clarifies the glass raw materials at high temperatures to form molten glass that meets the requirements for forming. Glass furnaces play a crucial role in glass manufacturing and are indispensable equipment in the glass production process.

[0003] A manual winch is a machine with a vertically installed cable drum that can wind but not store rope under power. It also refers to a winch whose axis of rotation is perpendicular to the deck. It is a self-protection and towing device for vehicles and ships. It can be used for self-rescue and rescue in harsh environments such as snow, swamps, deserts, beaches, and muddy mountain roads. It can also be used for clearing obstacles, towing objects, and installing facilities under other conditions.

[0004] Glass kilns are typically designed with multiple openings, including the neck water tank opening, liquid level measuring hole, temporary lance mounting hole, and various observation and material handling ports. Each of these openings presents a sealing challenge. Smaller openings can be sealed with refractory materials or metal doors, while larger openings require the use of high-temperature resistant hanging bricks for sealing. Typically, a manual winch is used to pull the high-temperature resistant hanging bricks to create the sealing structure.

[0005] Currently, most manual winches used for lifting glass kilns during sealing operations are directly derived from manual winches used in the building materials industry. These winches are large, complex to operate, and inconvenient for personnel to transport and carry. Furthermore, when the operator turns the handle to release the rope, if it is not quickly and urgently locked, the rope may rotate with the shaft, resulting in poor overall convenience, adjustability, and safety. This invention proposes a manual winch device and application method for glass kilns. It is used on the sealing structures of glass kilns where bricks need to be suspended. It features a simple-to-operate, high-temperature resistant brick-lifting winch that can be manually cranked to lift and adjust the bricks. The winch automatically limits the height at any height when the handle is released, and has bidirectional limit self-locking. It can be easily operated by a single person. The installation method can be selected based on the sealing location and actual conditions of the glass kiln, such as direct installation or connection to a stable support. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides a manual winch device and application method for glass kilns. It features adjustable lifting height for high-temperature resistant hanging bricks, automatic limit setting at any height when the handle is released, bidirectional limit self-locking, and easy single-person operation. This solves the problems of current manual winches used in glass kiln lifting operations, which are mostly based on manual winches from the building materials industry. These winches are bulky, complex to operate, and inconvenient for personnel to transport and use. Furthermore, when the operator turns the handle to release the rope, if it is not quickly and urgently locked, the rope may rotate with the shaft, resulting in poor overall convenience, adjustability, and safety.

[0018] A manual winch device for a glass kiln and its application method, characterized by comprising the following steps:

[0019] 1) Two installation methods: First, depending on the actual usage needs and installation conditions, the mounting bracket can be connected to the support base plate by passing the fastening bolts through the first and second mounting adjustment holes in sequence. Then, the mounting bracket and the support base plate can be tightly connected by the fastening nuts and fastening bolts. Finally, the electric push rod can be started by connecting the synchronous starter to the external power supply to drive the support base plate to a suitable height for use. Second, depending on the actual usage needs and installation conditions, the mounting bracket can be fixed by passing the fastening bolts through the first mounting adjustment hole in sequence and threading them through the required installation position for use.

[0020] 2) When the upward lifting and winding motion is required, hold the second crank handle to drive the second ratchet, second self-locking disc, second pawl, second limit shaft and second gear to be pulled outward. Rotate the second locking block into the inner wall of the second self-locking disc for limit and fixation. At this time, the second gear disengages from the second transmission gear ring, and then pushes the first self-locking disc into the groove inside the outer wall of the mounting bracket. Hold the first handle to drive the first crank handle to rotate clockwise, so that the first pawl is engaged and disengaged in the surface groove of the first ratchet. The clockwise rotation of the first crank handle drives the first self-locking disc and the first gear to rotate clockwise. The meshing of the first gear drives the first transmission gear ring and the winch shaft to rotate clockwise, so that the winch reinforcement wire rope on the surface of the winch shaft drives the high-temperature resistant hanging brick to perform a winding and lifting motion. When you release the handle, the first pawl is engaged in the surface groove of the first ratchet for self-locking.

[0021] 3) When a downward release is required; hold the first crank handle to pull out the first ratchet, first self-locking disc, first pawl, first limit shaft, and first gear. Rotate the first locking block into the inner wall of the first self-locking disc for limit fixation. At this time, the first gear disengages from the first transmission gear ring, and then pushes the second self-locking disc into the groove on the outer wall of the mounting bracket. Hold the second handle to rotate the second crank handle counterclockwise, causing the second pawl to engage and disengage in the surface groove of the second ratchet in a reciprocating motion. The counterclockwise rotation of the second crank handle drives the second self-locking disc and the second gear to rotate counterclockwise. The meshing of the second gear drives the second transmission gear ring and the winch shaft to rotate counterclockwise, causing the winch reinforcement wire rope on the surface of the winch shaft to carry the high-temperature resistant hanging brick in a release and descent motion. When released, the second pawl engages in the surface groove of the second ratchet for self-locking.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides a manual winch device and application method for a glass kiln, which has the following beneficial effects:

The first grip 21 and the second grip 22 are designed to work together. When in use, the operator can grip the first grip 21 and crank the first crank handle 10 clockwise, causing the first ratchet 6, the first self-locking disc 5, and the first gear 4 to rotate clockwise. This, in turn, engages the first transmission gear ring 3, causing it to rotate clockwise on the winch shaft 2, winding up the surface winch reinforced steel wire rope and lifting the high-temperature resistant hanging bricks. At this time, the second gear 13 disengages from the second transmission gear ring 12, and the operator releases the first grip 21. The pawl 7 engages with the tooth groove on the surface of the first ratchet 6 for self-locking. When it is necessary to rotate the winch shaft 2 counterclockwise, the operator holds the first crank handle 10 to pull out the first ratchet 6, the first self-locking disc 5, the first pawl 7, the first limit shaft 8, and the first gear 4. Then, the operator can hold the second handle 22 and crank the second crank handle 19 counterclockwise to rotate the second ratchet 15, the second self-locking disc 14, and the second gear 13 counterclockwise. The second gear 13 then meshes and drives the second transmission gear ring. The 12 pairs of winch shafts 2 rotate counterclockwise to wind up the surface winch reinforced steel wire rope, which drives the high-temperature resistant hanging brick to descend. At this time, the first gear 4 disengages from the first transmission gear ring 3. When the operator releases the second handle 22, the second pawl 16 engages in the surface tooth groove of the second ratchet 15 for self-locking. This achieves the functions of lifting and adjusting the high-temperature resistant hanging brick during the sealing operation of the glass kiln, automatically limiting the position when the handle is released at any height, and providing bidirectional limit self-locking. It can be easily operated by a single person.

[0025] 2. The manual winch device for the glass kiln and its application method, through the coordinated arrangement of the supporting base plate 25, electric push rod 26, stable support frame 27, limiting stabilizing plate 28, connecting support frame 29 and stabilizing legs 30, allows the user to select the mounting frame 1 to install and connect with the supporting base plate 25 according to actual needs. Then, the connecting support frame 29 is rotated to open the stabilizing legs 30 until they abut against the limiting stabilizing plate 28 for stable support. Subsequently, the electric push rod 26 is activated by the synchronous starter to drive the device to adjust up and down to a suitable height as needed. This provides stable support and adjusts the operating height of the manual winch device for the glass kiln, while also facilitating the installation, disassembly, folding, carrying, or storage of the stabilizing base.
