Description

Technical Field

[0001] This utility model relates to a crucible for zinc casting of cable main cables. Background Technology

[0002] During the maintenance and manufacturing of the main cable of a cable crane, zinc alloy needs to be cast at parts such as cable strand joints to achieve a firm connection and corrosion protection. Traditional zinc casting operations usually involve directly melting and pouring using a crucible. However, crucibles are relatively brittle and are prone to cracking during hoisting and tilting if subjected to impacts or uneven internal stress, leading to leakage of high-temperature molten zinc and posing a serious safety hazard.

[0003] Based on the above problems, we designed a leak-proof crucible for zinc casting of the main cable of a cable machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a leak-proof crucible for zinc casting of the main cable of a cable winch.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A crucible for zinc casting of the main cable of a cable winch, comprising,

[0007] The inner pot body has an outlet at the top edge and two lifting lugs are symmetrically arranged on the top of the inner pot body. The two lifting lugs are located on the same diameter line of the inner pot body, and the diameter line is perpendicular to the diameter line of the outlet.

[0008] The outer pot body has a slot at the top edge, the inner pot body is detachably installed inside the outer pot body, and the outlet extends out to the outside of the outer pot body through the slot.

[0009] The lifting assembly includes two components, both of which are installed on the same diameter line of the outer pot body and correspond to the lifting lugs.

[0010] A lateral traction component is provided at the lower part of the outer pot body. After being hoisted to the predetermined position, the outer pot body is rotated along the hoisting position by pulling the lateral traction component upward, thereby allowing the molten zinc in the inner pot body to be discharged through the outlet.

[0011] The inner pot is made of graphite crucible, which is more resistant to zinc corrosion and has better thermal conductivity.

[0012] The outer pot body is made of high-strength steel, which has sufficient strength and a melting point significantly higher than zinc, making it more stable in supporting the graphite crucible.

[0013] Preferably, a U-shaped groove is provided at the top of the outer pot body, corresponding to the position of the lifting assembly. The lifting assembly includes a rotating bracket, a lifting plate, a bushing, a pin, and a locking rod. The rotating bracket is fixed to the outer side of the outer pot body near the top and corresponds to the U-shaped groove. The bushing is fixed to the lower end of the lifting plate. The pin passes through the bushing, and both ends of the pin are fixed to the rotating bracket. The bushing rotates coaxially along the pin. A lifting hole is provided through the side of the lifting plate. The locking rod is fixedly installed on the side of the lifting plate facing the outer pot body. When the lifting device lifts the outer pot body through the lifting hole, the lifting plate rotates along the pin, thereby causing the locking rod to be inserted into the interior of the outer pot body through the U-shaped groove to fix the inner pot body.

[0014] Preferably, a limiting frame is fixed to the outside of the rotating bracket, and the limiting frame limits the outward rotation of the lifting plate. When the lifting plate is limited by the limiting frame, the locking rod moves to the outside of the U-shaped groove.

[0015] Preferably, when the locking rod enters the outer pot body through the U-shaped groove, the end of the locking rod is located inside the lifting lug.

[0016] Preferably, the lateral traction component includes a ring body and a second lifting lug, the second lifting lug being disposed on the outside of the ring body and located on the diameter line of the ring body, and the ring body being fixed to the outer pot body.

[0017] Preferably, the ring body and the second lifting lug are integrally cast structures.

[0018] The beneficial effects of this utility model are:

[0019] One advantage is the nested design of the inner and outer pots. The inner pot is made of graphite, which is resistant to zinc corrosion and has good thermal conductivity, and is responsible for melting zinc; the outer pot is made of high-strength steel as a protective shell. Even if the brittle graphite inner pot breaks during transportation or use, the outer pot can effectively contain the molten zinc, completely eliminating the risk of zinc leakage and greatly improving operational safety.

[0020] Secondly, through a unique lifting component design, the locking rod can be automatically driven to rotate inward during the lifting process, forming a firm lock on the inner pot. This feature is especially important in strong winds or when working at heights, effectively preventing the inner pot from swaying or falling out of the outer pot, ensuring stability during the lifting process.

[0021] Thirdly, the lateral traction component adopts an integrally cast ring and second lifting lug, which avoids the risk of cracking of welded lifting lugs, resulting in stronger load-bearing capacity and longer service life. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] See Figures 1 to 4 The crucible shown is for zinc casting of the main cable of a cable winch, comprising:

[0033] The inner pot body 1 has an outlet 11 at the top edge. Two lifting lugs 12 are symmetrically arranged on the top of the inner pot body 1. The two lifting lugs 12 are located on the same diameter line of the inner pot body 1, and the diameter line is perpendicular to the diameter line of the outlet 11.

[0034] The outer pot body 2 has a slot 21 at the top edge. The inner pot body 1 is detachably installed inside the outer pot body 2. A small gap is maintained between the inner pot body 1 and the outer pot body 2 to avoid the inner pot body 1 from getting stuck due to thermal expansion. The outlet 11 extends to the outside of the outer pot body 2 through the slot 21.

[0035] Lifting assembly 3, two of which are installed on the same diameter line of the outer pot body 2 and correspond to the lifting lug 12;

[0036] Lateral traction component 4 is located at the lower part of the outer pot body 2. After being hoisted to the predetermined position, the outer pot body 2 is rotated along the hoisting position by pulling the lateral traction component 4 upward, thereby allowing the molten zinc in the inner pot body 1 to be discharged through the outlet 11.

[0037] In the above technical solution, an inner pot body 1 and an outer pot body 2 are used in combination.

[0038] When melting zinc blocks, the inner pot 1 is used to support the zinc blocks and is heated to about 520 degrees Celsius. Once the zinc blocks have melted into molten zinc, the inner pot 1 is placed inside the outer pot 2 using clamps or a lifting device.

[0039] Then, the hoisting components 3 on both sides are lifted by hoisting tools to hoist the outer pot body 2 to the position where zinc pouring is required.

[0040] After reaching the predetermined position, the lateral traction component 4 is hooked by a hand-cranked hoist or an electric hoist, and an upward force is applied so that the outer pot body 2 rotates along the connection position of the hoisting assembly 3 and the lifting device, and the zinc liquid is poured to the predetermined position using the outlet nozzle 11.

[0041] In the above technical solution, the inner pot 1 is used for high-temperature heating, while the outer pot 2 is used for later load-bearing.

[0042] The inner pot body 1 is made of graphite crucible, which is more resistant to zinc corrosion and has better thermal conductivity.

[0043] The outer pot body 2 is made of high-strength steel, which has sufficient strength and a melting point significantly higher than zinc, making it more stable in supporting the graphite crucible.

[0044] Graphite crucibles are brittle and therefore easily broken. The outer pot body 2 is used to support them, so even if the inner pot body 1 breaks, the molten zinc will not spill, making it safer.

[0045] Graphite is a very stable material; molten zinc hardly wets or reacts with it. This means that molten zinc will not stick to the crucible wall, can be poured out cleanly, and has a long crucible lifespan.

[0046] Graphite can withstand rapid temperature changes and is not prone to cracking, making it very suitable for intermittent smelting operations.

[0047] See Figure 2 and Figure 3 As shown, a U-shaped groove 211 is provided on the top of the outer pot body 2, corresponding to the position of the lifting assembly 3. The lifting assembly 3 includes a rotating bracket 31, a lifting plate 32, a bushing 33, a pin 34, and a locking rod 35. The rotating bracket 31 is fixed to the outer side of the outer pot body 2 near the top and corresponds to the U-shaped groove 21. The bushing 33 is fixed to the lower end of the lifting plate 31. The pin 34 passes through the bushing 33, and both ends of the pin 34 are connected to the rotating bracket 31. The bracket 31 is welded and fixed. The bushing 33 rotates coaxially along the pin 34. The side of the lifting plate 32 has a lifting hole 36. The locking rod 35 is fixedly installed on the side of the lifting plate 32 facing the outer pot body 2. When the lifting device lifts the outer pot body 2 through the lifting hole 36, the lifting plate 32 rotates along the pin 34, thereby causing the locking rod 35 to be inserted into the interior of the outer pot body 2 through the U-shaped groove 211 to fix the inner pot body 1.

[0048] In the above technical solution, when the lifting plate 32 rotates to the limit position in the direction of the outer pot body 2, the locking rod 35 is in contact with the upper end of the inner pot body 1, or leaves a small gap.

[0049] In the above technical solution, when the lifting plate 32 is lifted, due to the gravity applied by the outer pot body 2, the lifting plates 32 on both sides rotate inward along the pin shaft 34, thereby limiting and fixing the inner pot body 1 through the locking rod 35.

[0050] Especially during construction in strong winds, it can prevent the inner pot body 1 and the outer pot body 2 from separating.

[0051] See Figure 2 , Figure 3 and Figure 4 As shown, a limiting frame 331 is fixed to the outside of the rotating bracket 31. The limiting frame 331 limits the outward rotation of the lifting plate 32. When the lifting plate is limited by the limiting frame, the locking rod moves to the outside of the U-shaped groove.

[0052] The above technical solution mainly limits the outward rotation of the lifting plate 32, so as to ensure that the lifting plate 32 is always tilted upward when waiting for lifting, so that the lifting tool can hook the lifting hole 36.

[0053] See Figure 1 As shown, when the locking rod 35 enters the outer pot body 2 through the U-shaped groove 21, the end of the locking rod 35 is located inside the lifting lug 12.

[0054] The above-mentioned technical solution plays a sufficient protective role because when the outer pot body 2 is a split type, the bottom of the outer pot body 2 is sealed by welding. When the bottom of the outer pot body 2 falls off, the locking rod 35 can be temporarily used to cooperate with the lifting lug 12 to prevent the inner pot body 1 from falling off.

[0055] Of course, in order to avoid the bottom of the outer pot body 2 falling off, we mainly use an integrally cast outer pot body 2.

[0056] See Figure 1 As shown, the lateral traction component 4 includes a ring body 41 and a second lifting lug 42. The second lifting lug 42 is disposed on the outside of the ring body 41 and located on the diameter line of the ring body 41. The ring body 41 is fixed to the outer pot body 2.

[0057] The ring and the second lifting lug are cast as a single unit.

[0058] In the above technical solution, the design of the ring body 41 and the second lifting lug 42 is adopted, and the ring body 41 and the second lifting lug 42 are integral structures. Compared with the traditional welded lifting lug, the second lifting lug 42 and the ring body 41 of this device have higher integrity, avoiding the lifting lug breakage during the lifting process.
