Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coiled core transformer manufacturing technology, specifically relating to a hoisting tool for manufacturing coiled core transformers. Background Technology
[0002] A wound-core transformer is a type of transformer whose core is made using a winding process. During its manufacturing process, silicon steel strips are continuously wound into a closed circular, elliptical, or other shaped core. Currently, wound-core transformers are typically produced using specialized hoisting equipment.
[0003] Existing hoisting equipment for producing wound-core transformers typically uses gantry cranes to lift and transport them. While this method is effective, it presents several challenges in practice. During hoisting, the wound-core transformer is prone to horizontal swaying, leading to load shifting and potential safety hazards, thus affecting the stability and safety of the hoisting process. Utility Model Content
[0004] In view of this, the present invention provides a hoisting fixture for the production of wound core transformers. The hoisting mechanism can eliminate horizontal swaying during the hoisting process of wound core transformers, ensure the straightness of the vertical lifting trajectory, and avoid safety hazards caused by load deviation.
[0005] To solve the above-mentioned technical problems, this utility model provides a hoisting fixture for the production of wound core transformers, including a gantry frame and a hoisting mechanism set on its upper end. The inner cavity of the gantry frame is provided with guide components on both sides for guiding the hoisting mechanism. The guide components include guide plates symmetrically arranged on both sides of the inner cavity of the gantry frame. A guide rod is slidably connected to the middle of the hoisting mechanism. Guide wheels are rotatably connected to both ends of the guide rod. The guide wheels are slidably engaged with the adjacent guide plates on the same side. The two ends of the guide rod are also provided with limiting components for limiting their movement, thereby eliminating horizontal swaying during the hoisting process of the wound core transformer, ensuring the straightness of the vertical lifting trajectory, and avoiding safety hazards caused by load deviation.
[0006] The limiting assembly includes mounting plates symmetrically arranged on both sides of the end of the guide rod. The guide plates are located between two adjacent mounting plates on the same side, thus playing a preliminary limiting role.
[0007] The limiting assembly also includes limiting wheels that are rotatably connected to the outer ends of the mounting plate. The two sides of the guide plate contact the adjacent limiting wheels on the same side, thereby suppressing the deviation of the guide rod.
[0008] The hoisting mechanism includes an electric hoist movably mounted on the upper end of the gantry frame. The end of the electric hoist's wire rope is equipped with a hoisting plate. The hoisting plate has sliding grooves on both sides, and sliding hangers are slidably connected at both ends between the two sliding grooves. The lower end of each sliding hanger is equipped with a hook. The guide rod is slidably connected to the sliding hole in the middle of the hoisting plate. The hoisting plate is also equipped with a locking component for locking the sliding hangers, which serves the hoisting function.
[0009] The locking assembly includes fixed toothed plates respectively set at the bottom of the slide groove, and limiting toothed plates are provided at the bottom of the inner end of the sliding hanger. The fixed toothed plates are movably engaged with the adjacent limiting toothed plates on the same side, thereby limiting the sliding hanger and the hook.
[0010] The hooks are threadedly connected to the screw holes at the bottom of the sliding hanger, which makes it convenient for relevant personnel to replace and adjust them.
[0011] The upper end of the sliding hanger does not contact the upper end of the chute, and the bottom of the inner cavity of the sliding hanger does not contact the lower end of the hoisting plate.
[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0013] 1. During the hoisting process, the guide rod moves synchronously with the hoisting plate, and the guide wheels at both ends roll along the guide plate inside the gantry frame, forming a double guiding constraint. At the same time, the limit wheels are close to both sides of the guide plate to suppress the deviation of the guide rod, eliminate the horizontal swaying during the hoisting of the coiled iron core transformer, ensure the straightness of the vertical lifting trajectory, and avoid safety hazards caused by load deviation.
[0014] 2. Based on the actual width of the lifting ring of the wound core transformer, move the sliding hanger upwards in sequence, and then drive it to slide laterally along the slide groove to adapt to different sizes of wound core transformers. After moving into place, release the sliding hanger, and the sliding hanger falls down, so that its upper limit tooth plate engages with the fixed tooth plate to fix it, thereby realizing the limit of the sliding hanger and the hook, and ensuring the accurate hook spacing.
[0015] 3. Threaded hooks make it easy for relevant personnel to replace and adjust them. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0022] This embodiment provides a hoisting fixture for the production of wound core transformers, such as... Figure 1-4 As shown: It includes a gantry frame 100 and a hoisting mechanism disposed on its upper end. The inner cavity of the gantry frame 100 is provided with guide components on both sides for guiding the hoisting mechanism. The guide components include guide plates 200 symmetrically disposed on both sides of the inner cavity of the gantry frame 100. A guide rod 201 is slidably connected to the middle of the hoisting mechanism. Guide wheels 202 are rotatably connected to both ends of the guide rod 201. The guide wheels 202 are slidably engaged with the adjacent guide plates 200 on the same side. The two ends of the guide rod 201 are also provided with limiting components for limiting its movement.
[0023] During the hoisting process, the guide rod 201 moves synchronously with the hoisting plate 401, and the guide wheels 202 at both ends roll along the guide plate 200 inside the gantry frame 100, forming a double guiding constraint, eliminating horizontal swaying during the hoisting process of the coiled iron core transformer, ensuring the straightness of the vertical lifting trajectory, and avoiding safety hazards caused by load deviation.
[0024] like Figure 1-3 As shown, the limiting assembly includes mounting plates 300 symmetrically arranged on both sides of the end of the guide rod 201. The guide plates 200 are located between two adjacent mounting plates 300 on the same side. The limiting assembly also includes limiting wheels 301 rotatably connected to the outer ends of the mounting plates 300. The two sides of the guide plate 200 are in contact with the adjacent limiting wheels 301 on the same side. The limiting wheels 301 are in close contact with the two sides of the guide plate 200 to suppress the deviation of the guide rod 201.
[0025] like Figure 1-4As shown, the hoisting mechanism includes an electric hoist 400 movably mounted on the upper end of the gantry frame 100. The electric hoist 400 is slidably engaged with the guide rail groove on the upper end of the gantry frame 100. The end of the wire rope of the electric hoist 400 is provided with a hoisting plate 401. Sliding grooves are provided on both sides of the hoisting plate 401. Sliding hangers 402 are slidably connected at both ends between the two sliding grooves. The upper end of the sliding hanger 402 does not contact the upper end of the sliding groove, and the bottom of the inner cavity of the sliding hanger 402 does not contact the lower end of the hoisting plate 401. The lower end of the sliding hanger 402 is provided with a hook 403. The guide rod 201 is slidably connected to the sliding hole provided in the middle of the hoisting plate 401. The hoisting plate 401 is also provided with a locking component for locking the sliding hanger 402. The hooks 403 are threadedly connected to the screw holes provided at the bottom of the sliding hanger 402, and the threaded hooks 403 are convenient for relevant personnel to replace and adjust.
[0026] Based on the actual width of the lifting ring of the coiled iron core transformer, the sliding hanger 402 is moved upward in sequence, and then driven to slide laterally along the slide groove to adapt to coiled iron core transformers of different sizes. After moving into position, the sliding hanger 402 is released and falls, so that its upper limit tooth plate 501 engages and is fixed with the fixed tooth plate 500, thereby achieving the limit of the sliding hanger 402 and the hook 403, ensuring that the distance between the hooks 403 is accurate. Then the hooks 403 are connected to the lifting ring on the iron core transformer, and then the electric hoist 400 is started, driving the lifting plate 401 to rise and fall vertically through the wire rope.
[0027] like Figure 1-4 As shown, the locking assembly includes fixed toothed plates 500 respectively disposed at the bottom of the slide groove, and limiting toothed plates 501 are provided at the bottom of the inner end of the sliding hanger 402. The fixed toothed plates 500 are respectively engaged with the adjacent limiting toothed plates 501 on the same side. The sliding hanger 402 is fixed by engaging with the fixed toothed plates 501 on it, thereby realizing the limiting of the sliding hanger 402 and the hook 403.
[0028] The working principle of the hoisting fixture for producing wound core transformers provided by this utility model is as follows: First, according to the actual width of the lifting ring of the wound core transformer, the sliding hanger 402 is moved upward in sequence, and then driven to slide laterally along the slide groove to adapt to wound core transformers of different sizes. After moving into position, the sliding hanger 402 is released, and the sliding hanger 402 falls, so that its upper limit tooth plate 501 engages and is fixed with the fixed tooth plate 500, thereby realizing the limiting of the sliding hanger 402 and the hook 403, ensuring that the spacing of the hook 403 is accurate. Then, the hook 403 is connected to the lifting ring on the core transformer. Then the electric hoist 400 is started, and the hoisting plate 401 is vertically raised and lowered through the wire rope. During the hoisting process, the guide rod 201 moves synchronously with the hoisting plate 401, and the guide wheels 202 at both ends roll along the guide plate 200 in the inner cavity of the gantry frame 100, forming a double guide constraint. At the same time, the limit wheel 301 is close to both sides of the guide plate 200 to suppress the deviation of the guide rod 201, eliminate the horizontal swaying during the hoisting of the coiled iron core transformer, ensure the straightness of the vertical lifting trajectory, and avoid safety hazards caused by load deviation. The threaded hook 403 is convenient for relevant personnel to replace and adjust.
[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
