Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing technology, specifically relating to hot-dip galvanizing hoisting equipment, and particularly to a rail-mounted hoisting frame for hot-dip galvanizing. Background Technology

[0002] In the hot-dip galvanizing production process, after the workpiece is immersed in the zinc bath, it needs to be transported to the resting area by a rail-mounted moving frame above the bath for zinc rinsing. This step is crucial to the final quality of the coating on the workpiece surface, requiring the movement and positioning to be smooth and without shaking. Any unstable movement may cause the unsolidified zinc layer on the workpiece surface to be damaged.

[0003] Currently, one of the widely used locking methods for mobile frames is the pin connection stop. This method involves a pre-set positioning base next to the track with pin holes, and the mobile frame body also has corresponding pin holes. When the mobile frame needs to be stopped, the operator needs to insert a rigid pin into both the track base pin hole and the mobile frame pin hole simultaneously to achieve mechanical locking.

[0004] However, this pin connection method has an inherent technical flaw: it requires that the pin holes on the moving frame be precisely aligned with the pin holes on the track base. In actual operation, due to the considerable inertia of the moving frame and the basket and workpiece it carries, it is extremely difficult to achieve millimeter-level alignment of the pin holes on the two stationary parts. The operator has to make minor back-and-forth adjustments to the moving frame by repeatedly jogging the drive device or manually pushing it. This process inevitably causes the basket and workpiece to sway back and forth.

[0005] The swaying and shaking of the workpiece disrupts the natural leveling and solidification process of the molten zinc on the surface, which can easily lead to the accumulation of zinc liquid to form "zinc nodules" or local lumps, resulting in uneven coating thickness. In addition, during the shaking, friction or collision may occur between the workpiece and the lifting fixture, or between the workpieces themselves, which can scratch or knock off the zinc coating that has not yet fully solidified, causing surface defects (uncoated spots), which seriously affect the product's appearance and corrosion resistance.

[0006] Therefore, how to avoid the swaying of the suspended basket during the positioning and moving process is a technical problem that urgently needs to be solved in this field.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0008] This disclosure provides at least one type of rail-mounted hot-dip galvanizing hoist to solve the technical problem of basket swaying.

[0009] This disclosure provides an improved over-track hot-dip galvanizing lifting frame, comprising: a movable frame and a track for traveling above a galvanizing bath; the movable frame is provided with a front moving wheel and a rear moving wheel at its bottom, and at least one receiving part is fixedly provided on one or both sides of the track; a first locking part, which is adapted to be inserted into any of the receiving parts in front of the target workstation so that the first locking part abuts against the side of the front moving wheel; a second locking part, which is adapted to be inserted into the receiving part at the rear of the movable frame when the movable frame travels along the track to the point where the first locking part abuts against the side of the front moving wheel, for abutting against the side of the rear moving wheel.

[0010] In one alternative embodiment, the receiving portion is a connecting hole that extends through the side of the track at equal intervals.

[0011] In one optional embodiment, the first locking part and the second locking part are fixed to the connecting hole by a pin or bolt. In one alternative embodiment, the receiving portion is a slot equally spaced on the side of the track.

[0012] In one alternative embodiment, the first locking part and the second locking part are plug-in and slot connection.

[0013] In one optional embodiment, a buffer layer is provided on the contact surface of the first locking part and the second locking part, the buffer layer being a rubber pad or a polyurethane material layer.

[0014] In one optional embodiment, the front moving wheel and the rear moving wheel include a metal disc and a rubber layer wrapped around the metal disc; the first locking part and the second locking part abut against the rubber layer.

[0015] In one alternative embodiment, a plurality of balls are provided on the inner wall of the track, which abut against the side of the metal disc.

[0016] In one alternative embodiment, a suspension rope structure is provided on the crossbar of the mobile frame to connect the suspended basket.

[0017] In one alternative embodiment, the length of the track is greater than the length of the galvanizing tank.

[0018] The beneficial effects of this utility model are that it improves the hoisting frame for hot-dip galvanizing by setting up receiving parts and insertable first and second locking parts that are discretely distributed along the track. This realizes a revolutionary positioning logic transformation of the moving frame from "dynamic precise alignment" to "static contact limit", fundamentally eliminating the swaying of the hoisting basket caused by positioning fine-tuning operations, and significantly improving the surface quality of hot-dip galvanized workpieces.

[0029] Research has revealed the following drawbacks of existing technologies: One of the widely used locking methods for mobile frames is pin-connected stop; this method involves a pre-set positioning base next to the track with pin holes, and the mobile frame body also has corresponding pin holes; when the mobile frame needs to be stopped, the operator must simultaneously insert a rigid pin into both the track base pin hole and the mobile frame pin hole to achieve mechanical locking.

[0030] However, this pin connection method has an inherent technical flaw: it requires that the pin holes on the moving frame be precisely aligned with the pin holes on the track base. In actual operation, due to the considerable inertia of the moving frame and the basket and workpiece it carries, it is extremely difficult to achieve millimeter-level alignment of the pin holes on the two stationary parts. The operator has to make minor back-and-forth adjustments to the moving frame by repeatedly jogging the drive device or manually pushing it. This process inevitably causes the basket and workpiece to sway back and forth.

[0031] The swaying and shaking of the workpiece disrupts the natural leveling and solidification process of the molten zinc on the surface, which can easily lead to the accumulation of zinc liquid to form "zinc nodules" or local lumps, resulting in uneven coating thickness. In addition, during the shaking, friction or collision may occur between the workpiece and the lifting fixture, or between the workpieces themselves, which can scratch or knock off the zinc coating that has not yet fully solidified, causing surface defects (uncoated spots), which seriously affect the product's appearance and corrosion resistance.

[0032] Therefore, how to avoid the swaying of the suspended basket during the positioning and moving process is a technical problem that urgently needs to be solved in this field.

[0033] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] like Figures 1 to 3 As shown, some embodiments provide a rail-mounted hoisting frame for hot-dip galvanizing, including: a movable frame 1 and a track 2 for it to move above a galvanizing bath 3; this is the main moving structure of the hoisting frame. The movable frame 1 is a frame structure that carries the basket and workpiece and moves on the track 2. The track 2 is usually made of heavy-duty steel rails and is fixedly installed on both sides or above the galvanizing bath 3 to provide precise guidance and support for the movable frame 1. It is crucial that the length of the track 2 is greater than the length of the galvanizing bath 3, which ensures that the movable frame 1 can completely cover the immersion area of ​​the galvanizing bath 3 as well as the loading and unloading areas and the drying and settling areas at both ends of the bath. This realizes that the entire process of workpiece entering the bath, immersion, exiting the bath and drying is seamlessly completed on a single track, improving the continuity and automation of the production line.

[0037] The bottom of the mobile frame 1 is provided with a front moving wheel 11 and a rear moving wheel, and at least one receiving part 21 is fixedly provided on one or both sides of the track 2. The mobile frame 1 achieves smooth rolling on the track 2 through the front and rear moving wheel sets. The receiving part 21 is the core basic component of the positioning system of the present invention. Its essence is a series of standardized interfaces preset on the track 2. The receiving part 21 is arranged along one or both sides of the track 2. Its core value lies in providing a discrete and standardized array of positioning points. This design divides the continuous track into multiple definite workstations, so that the stopping position of the mobile frame 1 is no longer a continuous quantity estimated by the operator's visual estimation, but a discrete quantity bound to the positions of these fixed receiving parts 21. This fundamentally creates conditions for precise positioning. The receiving part 21 can achieve basic positioning when set on one side of the track, and can provide better force balance and stability when set symmetrically on both sides, which is especially suitable for heavy or wide mobile frames 1.

[0038] The first locking part 5 is adapted to be inserted into any receiving part 21 in front of the target workstation so that the first locking part 5 abuts against the side of the front moving wheel 11. The first locking part 5 is a key component for achieving pre-positioning (or reference positioning). Before the moving frame 1 starts to move towards the target workstation (such as the drying area), the operator first inserts the first locking part 5 into a receiving part 21 in front of the target workstation. At this time, the first locking part 5 is no longer a simple part, but is transformed into a fixed, immovable mechanical stop. Its revolutionary significance lies in completely changing the positioning logic: from the traditional "moving frame moves to an approximate position and then finely adjusts itself to align with a fixed lock hole" to "the moving frame directly moves towards a pre-set physical stop". When the side of the front moving wheel 11 of the moving frame 1 contacts the first locking part 5, the movement stops immediately. This process does not require any fine-tuning because the position of the stop is absolute, thereby eliminating the shaking of the basket and workpiece caused by repeated jogging or manual pushing and pulling of the moving frame 1 for precise positioning.

[0039] The second locking part 6 is adapted to be inserted into the receiving part 21 at the rear of the moving frame 1 when the moving frame 1 travels along the track 2 to abut against the side of the first locking part 5 and the front moving wheel 11. The second locking part 6 is a component that realizes safety locking (or final positioning). After the first locking part 5 has completed the pre-positioning and the moving frame 1 has accurately stopped, the second locking part 6 begins to function. The operator inserts it into the nearest receiving part 21 at the rear of the moving frame 1 so that it abuts against the side of the rear moving wheel. In this way, the front and rear directions of the mobile frame 1 are constrained by the first locking part 5 and the second locking part 6 respectively, forming a stable "clamping" state. The main function of the second locking part 6 is to prevent the mobile frame 1 from moving unexpectedly due to external factors (such as wind, equipment vibration or accidental collision) during the static drying process. It works together with the first locking part 5 to form a complete "one-block-one-lock" positioning system, which ensures both the efficiency and accuracy of positioning (the first locking part 5 is responsible) and the absolute safety after stopping (the second locking part 6 is responsible).

[0040] The receiving part 21 has equally spaced connecting holes that pass through the side of the track 2; the first locking part 5 and the second locking part 6 are fixed to the connecting holes by pins or bolts; the pins or bolts as locking parts have the advantages of low manufacturing cost, sturdiness and durability, and intuitive operation. By selecting connecting holes at different positions, the positioning position can be flexibly adjusted. This combination of "hole + pin" realizes standardized and modular positioning, and maintenance and replacement are also very convenient.

[0041] The receiving part 21 is a slot that is equally spaced on the side of the track 2; the first locking part 5 and the second locking part 6 are for connecting the plug and the slot; compared with the round hole, the strip slot provides a larger tolerance range for the plug. The plug does not need to be aligned in the circumferential direction as required by the pin during the insertion process. It can simply slide into the slot. In some cases, it is more convenient to operate. The contact area between the plug and the slot is usually larger and the force is more uniform. It may have better impact resistance and shear resistance.

[0042] A buffer layer, which is a rubber pad or a polyurethane material layer, is provided on the contact surface of the first locking part 5 and the second locking part 6. This feature is an important optimization of the "pre-positioning" process. Although the first locking part 5 is used as a stop to avoid fine-tuning sway, the moving frame 1 will still generate an impact when it hits the rigid stop at a certain speed. Although this impact force will not cause the basket to swing at a low frequency, it may generate high-frequency vibration, which still has a potential impact on the solidification of the workpiece coating and the service life of the equipment. The rubber or polyurethane buffer layer on the contact surface can transform the rigid collision into a flexible contact. The buffer layer effectively absorbs and dissipates the collision energy through its own elastic deformation, so that the moving frame 1 can achieve a true "soft stop" or "impact-free stop". This further ensures the ultimate stability of the basket and the workpiece, and almost completely eliminates any adverse effects on the quality of the galvanized surface caused by the positioning operation itself. At the same time, it also protects the moving wheel 11 and the locking part itself, and extends the service life of the equipment.

[0043] The front and rear moving wheels include a metal disc 12 and a rubber layer 14 wrapped around the metal disc 12; the first locking part 5 and the second locking part 6 abut against the rubber layer 14; the moving wheels themselves need the rubber layer 14 to provide adhesion to the track 2 and reduce running noise. This solution allows the locking part to directly contact the side of the rubber layer 14, which means that the rubber tire itself becomes a built-in, large-scale buffer, and its buffering effect is more significant than that of a small-area buffer layer. This design does not require additional parts, greatly simplifies the structure, reduces costs, and is a perfect embodiment of the "structure is function" design concept. The metal disc 12 provides the necessary structural strength and rigidity, while the outer rubber layer 14 simultaneously undertakes the dual functions of walking and buffering.

[0044] Several ball bearings 4 are installed on the inner wall of track 2, which abut against the side of metal wheel 12. During long-distance travel, the moving frame 1 may sway laterally or deviate due to uneven track or load eccentricity. The ball bearings 4 (or guide wheels / limiting wheels) installed on the inner wall of track 2 maintain rolling contact with the side of metal wheel 12, forming a lateral constraint mechanism. They are like guide rails, which restrict the lateral freedom of the moving wheel assembly and ensure that the moving frame 1 always runs smoothly along the center line of track 2 without swaying left or right. This further improves the overall stability during operation and lays a solid foundation for achieving accurate and stable positioning.

[0045] A suspension rope structure is installed on the crossbar of the movable frame 1 to connect the suspended basket. The suspension rope structure (which can be a wire rope, chain, etc. with a hook) is the connecting part between the movable frame 1 and the galvanized suspended basket. Its flexibility allows the suspended basket to have a certain degree of self-adaptability during lifting, lowering and moving. However, it is precisely this flexibility that makes the suspended basket and the workpiece inside it prone to becoming a "swinging pendulum". The core value of this invention is that, through the above series of innovations, the root cause of this "pendulum" swing is suppressed to the greatest extent possible - namely, the non-stable operation in the positioning stage. A stable movable frame 1 is a prerequisite for obtaining a stable suspended basket.

[0046] The length of track 2 is greater than the length of galvanizing tank 3. This design ensures the integrity and rationality of the production process. One end of the extended track is used for loading and unloading workpieces, while the other end provides a sufficient drying and settling area. After the workpiece is taken out of galvanizing tank 3, there is enough space to move it directly above the tank body and complete the free leveling, dripping and solidification of the zinc liquid in the settling area. This avoids the high-temperature zinc liquid vapor from affecting other workpieces or equipment in the tank and also ensures operational safety.

[0047] Overall workflow: Preparation stage: According to the production instructions, the operator inserts the first locking part 5 (such as a pin or plug) into the receiving part 21 (such as a connecting hole or slot) on the track 2 corresponding to the front of the drying station. At this time, the first locking part 5 becomes a preset mechanical stop. During the travel and positioning phase: The operator drives the mobile frame 1, carrying a basket fully loaded with galvanized workpieces, to move forward slowly and steadily along the track 2. The ball bearings 4 in the track 2 continuously contact the side of the metal wheel 12 to ensure that the mobile frame 1 runs in a straight line without lateral sway. When the side of the rubber layer 14 of the front moving wheel 11 gently abuts against the contact surface of the first locking part 5 (which may have a buffer layer), the mobile frame 1 stops smoothly and without impact under the buffering effect. Safety locking phase: After the mobile frame 1 comes to a stop, the operator inserts the second locking part 6 into the nearest receiving part 21 at the rear of the mobile frame 1, so that it abuts against the side of the rear moving wheel; After drying and subsequent steps: The workpiece is dried in zinc liquid under an absolutely stable condition. After completion, the second locking part 6 and the first locking part 5 are pulled out in reverse order, and the moving frame 1 can then move to the next station.

[0048] In summary, this embodiment: By setting up a receiving part 21 that is discretely distributed along the track and an insertable first locking part 5 and a second locking part 6, a revolutionary positioning logic transformation from "dynamic precise alignment" to "static contact limit" is realized for the moving frame 1, which fundamentally eliminates the swaying of the basket caused by the positioning fine-tuning operation and significantly improves the surface quality of the hot-dip galvanized workpiece. By setting a buffer layer or using the rubber layer 14 of the moving wheel as a buffer medium, a "soft stop" effect is achieved when the moving frame 1 contacts the first locking part 5, which further reduces the impact and vibration during the positioning process and protects the coating solidification process and the life of the equipment itself. By setting the ball bearings 4 on the inner wall of the track to abut against the side of the metal wheel 12, the lateral stability of the moving frame 1 during operation is improved, laying a good motion foundation for precise positioning. By setting up a "one-block, one-lock" mechanism with the front and rear locking parts working in tandem, we have achieved rapid and accurate positioning as well as absolute safety after docking, which has greatly improved production operation efficiency and system reliability.
