Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a lifting tool for an electric melting core. Background Art

[0002] The electric melting core is an indispensable structure in the production and preparation of electric melting pipe fittings at present. Briefly speaking, when producing and preparing electric melting pipe fittings, it is necessary to wind wires around the outside of the electric melting core by a winding machine, and then place it in a mold for injection molding. After the material cools and forms, the electric melting core is demolded to obtain a complete electric melting pipe fitting.

[0003] However, in actual manufacturing, the shapes and sizes of the produced electric melting pipe fittings are diverse. Even for some large-sized special-shaped electric melting pipe fittings, large-sized split electric melting cores are required for production and preparation. Briefly speaking, the electric melting core includes an upper core body and a lower core body, and the two are installed together by stacking and clamping. Before the winding work, workers can separately send the upper core body and the lower core body to the winding machine platform, and then assemble the two before carrying out the winding work. However, after the winding work is completed outside the electric melting core by the winding machine, due to the existence of the wires, the upper core body and the lower core body cannot and cannot be disassembled for separate transportation. Moreover, due to the large volume and size of the electric melting core, only a crane can be used to lift it.

[0004] However, in the prior art, transporting the electric melting core by a crane is very troublesome. Since the electric melting core is composed of an upper core body and a lower core body, more chains are required to ensure stability during lifting, which makes the process of tying the electric melting core by workers with chains very long, not conducive to rapid production and processing. Moreover, during the lifting process, the chains are very likely to press the wires wound around the electric melting core, affecting the overall quality of the subsequent produced and formed electric melting pipe fittings. Summary of the Invention

[0005] The purpose of the utility model is to propose a lifting tool for an electric melting core in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is: how to ensure the production quality while ensuring the production efficiency of the electric melting core.

[0006] The purpose of the utility model can be realized by the following technical solutions: A lifting tool for an electric melting core, including a frame with a lifting ring fixed at the top, characterized in that the bottom of the frame has a core accommodating gap, two upper clamping plates and two lower clamping plates are slidably connected horizontally in the frame, the two upper clamping plates are located above the two lower clamping plates, when the two upper clamping plates slide closer to each other, an upper clamping opening is formed by surrounding between the two upper clamping plates, and when the two lower clamping plates slide closer to each other, a lower clamping opening located in the core accommodating gap is formed by surrounding between the two lower clamping plates.

[0007] This electric melting core hoisting tool uses a frame with a core-containing gap at the bottom as the main carrying body. The lifting ring is used in conjunction with a crane to lift or lower the frame. Inside the frame, there are two upper clamping plates that can move relative to each other and two lower clamping plates that can move relative to each other. When carrying out the hoisting work, the worker can first lift the frame by the crane in cooperation with the lifting ring. After adjusting the position, slowly lower it so that the frame covers the outside of the electric melting core through the core-containing gap at the bottom. At this time, both the two upper clamping plates and the two lower clamping plates can move relative to each other and approach. The upper clamping port formed by the enclosure between the two upper clamping plates clamps and positions the upper core body that constitutes the electric melting core. Similarly, the lower clamping port formed by the enclosure between the two lower clamping plates clamps and positions the lower core body that constitutes the electric melting core. On the premise of ensuring that the entire electric melting core is firmly positioned inside the frame, the worker operates the crane, and again lifts the frame together with the wound electric melting core through the cooperation of the lifting ring and the crane. Through the operation of the worker on the crane, the frame together with the electric melting core is sent into the injection mold. While ensuring the stable placement of the lower end of the electric melting core, the two upper clamping plates and the two lower clamping plates are separated from each other. Then, the worker operates the crane again, and through the cooperation of the lifting ring and the crane, the frame is lifted, so that the electric melting core can be taken out from the core-containing gap and placed stably on the injection mold. During the entire transfer operation process, there is no need for the worker to repeatedly tie or untie the chain of the electric melting core, which can effectively reduce the time spent in this process, effectively improve the production efficiency of a single electric melting pipe fitting, and through the upper clamping port formed by the cooperation of the two upper clamping plates to clamp and position the upper core body of the electric melting core, and through the lower clamping port formed by the cooperation of the two lower clamping plates to clamp and position the lower core body of the electric melting core, it can effectively prevent damage to the wires wound outside the electric melting core, thus achieving the advantage of ensuring the production quality of the electric melting pipe fitting.

[0008] In the above-mentioned electric melting core hoisting tool, upper arc grooves are provided on the opposite sides of the two upper clamping plates, and the upper clamping port is formed by the enclosure of the two upper arc grooves. Lower arc grooves are provided on the opposite sides of the two lower clamping plates, and the lower clamping port is formed by the enclosure of the two lower arc grooves. Through the cooperation of the two upper arc grooves and through the cooperation of the two lower arc grooves, the shape of the upper clamping port formed between the two upper clamping plates and the lower clamping port formed between the two lower clamping plates is more suitable for the electric melting core, ensuring the stability of positioning the electric melting core in the frame, and thus avoiding potential safety hazards during the hoisting process.

[0009] In the above-mentioned electric melting core hoisting tool, two horizontally arranged upper bearing rods and two lower bearing rods are arranged in parallel in the frame. The upper bearing rods are located above the lower bearing rods and face the same direction. The two upper clamping plates and the two upper bearing rods are slidably connected through a slide rail and a slider. The two lower clamping plates and the two lower bearing rods are slidably connected through a slide rail and a slider. Through this setting, the sliding directions of the two upper clamping plates and the two lower clamping plates are limited and guided, ensuring that the sliding directions of the two upper clamping plates and the two lower clamping plates always remain the same, avoiding interference between the upper and lower clamping plates and the electric melting core during sliding, and ensuring the clamping stability of the electric melting core.

[0010] In the above-mentioned electric melting core hoisting tool, the electric melting core hoisting tool further includes two horizontally arranged upper adjusting plates. An arc-shaped upper adjusting groove is formed on one side of each of the two upper adjusting plates facing each other. The two upper adjusting plates are arranged horizontally and fixed to the two upper clamping plates by bolts, and an upper adjusting opening located in the upper clamping opening is formed between the two upper adjusting grooves. For electric melting cores with different diameters at the upper and lower ends, especially for electric melting cores with a small outer diameter of the upper core and a large outer diameter of the lower core, workers can fix the upper adjusting plates to the two upper clamping plates by bolts according to the actual size requirements of the upper core, and clamp the upper core through the upper adjusting opening formed between the two upper adjusting plates, thereby ensuring the adaptability of the electric melting core hoisting tool.

[0011] In the above-mentioned electric melting core hoisting tool, the electric melting core hoisting tool further includes two horizontally arranged lower adjusting plates. An arc-shaped lower adjusting groove is formed on one side of each of the two lower adjusting plates facing each other. The two lower adjusting plates are arranged horizontally and fixed to the two lower clamping plates by bolts, and a lower adjusting opening located in the lower clamping opening is formed between the two lower adjusting grooves. For electric melting cores with different diameters at the upper and lower ends, especially for electric melting cores with a large outer diameter of the upper core and a small outer diameter of the lower core, workers can fix the lower adjusting plates to the two lower clamping plates by bolts according to the actual size requirements of the lower core, and clamp the lower core through the lower adjusting opening formed between the two lower adjusting plates, thereby ensuring the adaptability of the electric melting core hoisting tool. In addition, it is worth mentioning that for electric melting cores with the same diameter at the upper and lower ends and the maximum size, workers can disassemble each upper and lower adjusting plate and clamp the electric melting core only through the upper clamping opening formed between the two upper clamping plates and the lower clamping opening formed between the two lower clamping plates. Secondly, for other electric melting cores with different sizes, workers can correspondingly replace the upper and lower adjusting plates with different adjusting groove sizes, thereby ensuring the adaptability of the electric melting core hoisting tool.

[0012] In the above-mentioned electric melting core hoisting tool, upper spring resetters are provided at both ends of the two upper bearing rods, and lower spring resetters are provided at both ends of the two lower bearing rods. The output ends of the upper spring resetters are connected to the opposite side walls of the two upper clamping plates, and the output ends of the lower spring resetters are connected to the opposite side walls of the two lower clamping plates. The spring resetter is a specific prior art. Briefly speaking, it includes a housing with a driving actuator (i.e., a cylinder) and a spring installed inside, and a driving rod is provided at one end of the housing. The driving actuator and the driving rod are fixedly connected by the spring (due to the limitation of the internal channel of the housing, the spring can only expand and contract in the length direction), and the driving rod as the driving end is positioned on the side wall of the upper clamping plate or the lower clamping plate. By controlling the driving actuator, the driving rod drives the upper clamping plate or the lower clamping plate to move, realizing the clamping and positioning of the electric melting core. At the same time, due to the presence of the spring, it prevents the upper clamping plate (upper adjusting plate) and the lower clamping plate (lower adjusting plate) from exerting excessive force on the outer surface of the electric melting core.

[0013] In the above-mentioned electric melting core hoisting tool, upper cushion blocks are fixedly provided at both ends of each upper bearing rod, and the upper spring resetter is fixed on the upper cushion blocks. Lower cushion blocks are fixedly provided at both ends of each lower bearing rod, and the lower spring resetter is fixed on the lower cushion blocks. Through the setting of the upper cushion blocks, interference between the driving ends of the upper spring resetters and the sliding rails on the upper bearing rods is avoided. Through the presence of the lower cushion blocks, interference between the driving ends of the lower spring resetters and the sliding rails on the lower bearing rods is avoided.

[0014] In the above-mentioned electric melting core hoisting tool, the frame includes four vertical rods, two upper cross rods, and two lower cross rods. The two upper cross rods and the two lower cross rods are perpendicular to each other. The lower ends of two of the vertical rods are fixedly connected to both ends of the side wall of one of the lower cross rods, and the upper ends are fixedly connected to the side walls of one ends of the two upper cross rods. The lower ends of the other two vertical rods are fixedly connected to both ends of the side wall of the other lower cross rod, and the upper ends are fixedly connected to the side walls of the other ends of the two upper cross rods. The two lower bearing rods are fixedly connected to the two lower cross rods, and the core accommodating gap is formed between the two lower bearing rods. Through the cooperation of the four vertical rods, two upper cross rods, and two lower cross rods, it is ensured that the formed frame structure has a higher strength with relatively fewer required rods, and the weight of the frame is ensured to be lighter. In addition, two lower cross rods are used as carriers for the two lower bearing rods to be assembled, ensuring that the formed core accommodating gap is more regular and guaranteeing that the operation process of sleeving the frame on the electric melting core by a crane during the operation is more convenient.

[0015] In the above-mentioned electric melting core hoisting tool, a long strip-shaped adjustment hole is formed along the length direction on the outer wall near the upper end of each vertical rod. One of the upper bearing rods and two of the vertical rods are detachably connected by bolts in cooperation with the adjustment hole, and the other upper bearing rod and the other two vertical rods are detachably connected by bolts in cooperation with the adjustment hole. In this way, the two upper bearing rods can be slidably adjusted vertically within the frame, so that the upper clamping opening (upper adjustment opening) can approach or move away from the lower clamping opening (lower adjustment opening) according to the electric melting core of different heights, ensuring the adaptability of the electric melting core hoisting tool.

[0016] In the above-mentioned electric melting core hoisting tool, a horizontally arranged connecting rod is fixedly provided between the two upper cross rods. The connecting rod is parallel to the two lower cross rods, and the distance between the connecting rod and the two lower cross rods is equal. The lifting ring is fixedly provided on the connecting rod. The connecting rod can play a role in strengthening the structural strength of the top of the frame, and ensure that the lifting ring is more centered relative to the frame, avoiding skewing during the process of lifting the light.

[0017] Compared with the prior art, the electric melting core hoisting tool has the following advantages:

[0018] 1. Using the frame as the main body, two upper clamping plates are driven to move by the upper spring reset device, and two lower clamping plates are driven to move by the lower spring reset device. The upper core body of the electric melting core is clamped by the upper clamping opening formed between the two upper clamping plates, and the lower core body of the electric melting core is clamped by the lower clamping opening formed between the two lower clamping plates, so as to ensure the stable clamping of the whole electric melting core. There is no need to complexly bind the electric melting core with a chain, effectively improving the manufacturing efficiency of the electric melting pipe fitting, and avoiding the chain from pressing the wire arranged outside the electric melting core to prevent the wire from being crushed, effectively ensuring the production quality of the electric melting pipe fitting.

[0019] 2. Users can choose to install the upper adjustment plate on the upper clamping plate and the lower adjustment plate on the lower clamping plate according to the size of the electric melting core. The upper adjustment opening formed by enclosing between the two upper adjustment plates is used to clamp the upper core body of the electric melting core instead of the upper clamping opening, and the lower adjustment opening formed by enclosing between the two lower adjustment plates is used to clamp the lower core body of the electric melting core instead of the lower clamping opening, ensuring the adaptability of the electric melting core hoisting tool.

[0020] 3. The two upper bearing rods can be slidably adjusted along the height direction of the frame by the cooperation of bolts and adjustment holes, so that the electric melting core hoisting tool can be adapted to electric melting cores of different lengths for use. Description of the Drawings

[0032] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0033] Embodiment 1

[0034] As Figure 1 With Figure 2As shown, this embodiment is mainly used for electric fusion cores with different diameters at the upper and lower ends, and specifically refers to split electric fusion cores whose outer diameter at the lower end is the maximum outer diameter that can be accommodated by the frame 1 and whose outer diameter at the upper end is smaller than that at the lower end. The electric fusion core lifting tool includes a frame 1. Specifically, the frame 1 includes four vertical rods 16, two lower cross rods 18 and two upper cross rods 17. The two upper cross rods 17 are intersected with the two lower cross rods 18 in the direction of each other, and the intersection angle is 90 degrees. The lower ends of the two vertical rods 16 are welded and fixed to the side walls at both ends of one of the lower cross rods 18, the upper ends are welded and fixed to the side walls of one end of the two upper cross rods 17, and the lower ends of the other two vertical rods 16 are welded and fixed to the side walls at both ends of the other lower cross rod 18. The upper end is welded and fixed to the side wall of the other end of the two upper cross bars 17, and two upper bearing bars 14 and lower bearing bars 15 with L-shaped cross sections are arranged in the frame 1 along the horizontal direction. The two upper bearing bars 14 are arranged in parallel, and the two lower bearing bars 15 are arranged in parallel. The two lower bearing bars 15 are specifically welded to the two lower cross bars 18, so that the bottom of the frame 1 is located between the two lower bearing bars 15 to form a core capacity gap 2. A connecting rod 171 is welded and fixed between the two upper cross bars 17 at the top of the frame 1. The connecting rod 171 is parallel to the two lower cross bars 18 and has the same spacing as the two lower cross bars 18. A lifting ring 11 is installed on the connecting rod 171 near the middle by screwing or welding.

[0035] Combination Figure 3 A long strip-shaped adjustment hole 161 is vertically opened on the side wall of each vertical rod 16. The two upper bearing rods 14 are arranged parallel to the two lower bearing rods 15. The outer wall of one of the upper bearing rods 14 is in contact with the outer walls of two of the vertical rods 16. Bolts are passed through the adjustment holes 161 and screwed to the threaded holes opened on the outer walls of the upper bearing rod 14, so that the upper bearing rod 14 is clamped in place. The outer wall of another upper bearing rod 14 is in contact with the outer walls of the other two vertical rods 16. Bolts are passed through the adjustment holes 161 and screwed to the threaded holes opened on the outer walls of the upper bearing rod 14, so that the upper bearing rod 14 is clamped in place.

[0036] Combination Figure 5 As shown, slide rails are provided on the two upper bearing rods 14 and the two lower bearing rods 15 along the length direction. The electric fuse core lifting tool also includes two upper clamping plates 12 and lower clamping plates 13 which are arranged laterally and are in the shape of rectangular plates. Slide blocks for sliding connection with the slide rails are fixed near both ends of the lower side surfaces of each upper clamping plate 12 and each lower clamping plate 13. Upper arc grooves 122 are provided on the opposite sides of the two upper clamping plates 12, and lower arc grooves 132 are provided on the opposite sides of the two lower clamping plates 13. When the two upper clamping plates 12 move relative to each other, the two upper arc grooves 122 can be closed to form an upper clamping opening 121. Similarly, when the two lower clamping plates 13 move relative to each other, the two lower arc grooves 132 can be closed to form a lower clamping opening 131.

[0037] like Figure 1 and Figure 2 As shown, a rectangular upper pad 142 is provided at both ends of the two upper bearing rods 14, and a rectangular lower pad 152 is provided at both ends of the two lower bearing rods 15, an upper spring returner 141 is fixedly installed on each upper pad 142, and a lower spring returner 151 is fixedly installed on each lower pad 152, the two upper spring returners 141 located at one end of the two upper bearing rods 14 have their driving ends fixedly connected to one of the upper splints 12, the two upper spring returners 141 located at the other end of the two upper bearing rods 14 have their driving ends fixedly connected to the other upper splint 12, the two lower spring returners 151 located at one end of the two lower bearing rods 15 have their driving ends fixedly connected to one of the lower splints 13, and the two lower spring returners 151 located at the other end of the two lower bearing rods 15 have their driving ends fixedly connected to the other lower splint 13.

[0038] In addition, combined Figure 4 In order to ensure that the electric fuse core lifting tool can be adapted to the upper core body with a smaller outer diameter in the electric fuse core, an upper adjustment plate 3 is installed on each upper clamping plate 12 by bolts, and an arc-shaped upper adjustment groove 31 is opened on the opposite side of the two upper adjustment plates 3. The two upper adjustment grooves 31 cooperate and enclose to form an upper adjustment port 311 adapted to the outer diameter of the upper core, and the upper adjustment port 311 replaces the upper clamping port 121 to clamp the upper core body of the electric fuse core, and for electric fuse cores of different sizes, workers can replace the upper adjustment plates 3 with different adjustment groove sizes.

[0039] Operation principle: Before operation, the worker adjusts the positions of the two upper bearing rods 14 according to the height of the electrofusion core to be lifted, so that the two upper clamping plates 12 move relatively closer to or away from the two lower clamping plates 13, that is, appropriately adjust the distance between the upper adjustment port 311 and the lower clamping port 131. Then the worker uses a crane (overhead crane) to cooperate with the lifting ring 11 to lift the frame 1, and then lowers the frame 1 after adjusting the position, so that the frame 1 covers the electrofusion core through the core accommodating gap 2 at the bottom. At this time, each upper spring reset device 141 and each lower spring reset device 151 work to drive the two upper clamping plates 12 and the two lower clamping plates 13 to move closer. The lower clamping port 131 formed between the two lower clamping plates 13 clamps the lower core of the electrofusion core, and the upper adjustment port 311 formed between the two upper adjustment plates 3 clamps the upper core of the electrofusion core. On the premise of maintaining stable clamping, the worker operates the crane to cooperate with the lifting ring 11 to lift the frame 1 together with the electrofusion core. After moving it to the injection mold, each upper spring reset device 141 and each lower spring reset device 151 work, so that the two upper clamping plates 12 and the two lower clamping plates 13 move away from each other. At this time, the upper core disengages from the upper adjustment port 311 and the lower core disengages from the lower clamping port 131. Then the worker operates the crane to lift the frame 1 alone to complete the transfer of the electrofusion core.

[0040] Embodiment 2

[0041] The structure of this embodiment is roughly the same as that of Embodiment 1, and the difference is only that: as Figure 6 shown in Figure 7 This embodiment is mainly used for electrofusion cores with different diameters at the upper and lower ends, specifically for split electrofusion cores with outer diameters at both the upper and lower ends smaller than the maximum outer diameter that the frame 1 can accommodate. On both of the two lower clamping plates 13, there are lower adjustment plates 4 arranged horizontally and in the shape of rectangular plates. The two lower adjustment plates 4 and the two lower clamping plates 13 are both bolted and locked. On the opposite sides of the two lower adjustment plates 4, there are arc-shaped lower adjustment grooves 41 opened, and a lower adjustment port 411 is formed between the two lower adjustment grooves 41 to clamp the lower core instead of the lower clamping port 131. And for electrofusion cores with different outer diameters at the upper and lower ends, the worker can correspondingly replace the upper adjustment plates 3 with different upper adjustment groove 31 sizes and the lower adjustment plates 4 with different lower adjustment groove 41 sizes.

[0042] Embodiment 3

[0043] The structure of this embodiment is roughly the same as that of Embodiment 1 and Embodiment 2, and the difference is only that: as Figure 8 shown in Figure 9 This embodiment is mainly used for electrofusion cores with different diameters at the upper and lower ends, specifically for split electrofusion cores with the outer diameter at the upper end being the maximum outer diameter that the frame 1 can accommodate and the outer diameter at the lower end being smaller than the outer diameter at the upper end. Only the lower adjustment plates 4 need to be installed on the two lower clamping plates 13.

[0044] Example 4

[0045] The structure of this embodiment is substantially the same as that of Embodiment 1, Embodiment 2, and Embodiment 3. The difference is only that: as Figure 10 shown, this embodiment is mainly used for a split electric melting core with the same diameter at both the upper and lower ends, specifically referring to a split electric melting core whose outer diameters at both the upper and lower ends are equal to the maximum outer diameter that the frame 1 can accommodate. The upper core body of the electric melting core is clamped by the upper clamping opening 121 formed between the two upper clamping plates 12, and the lower core body of the electric melting core can be clamped by the lower clamping opening 131 formed between the two lower clamping plates 13.

Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0047] Although terms such as frame 1, lifting ring 11, upper clamping plate 12, upper clamping opening 121, upper arc-shaped groove 122, lower clamping plate 13, lower clamping opening 131, lower arc-shaped groove 132, upper bearing rod 14, upper spring reset device 141, upper cushion block 142, lower bearing rod 15, lower spring reset device 151, lower cushion block 152, vertical rod 16, adjustment hole 161, upper cross bar 17, connecting rod 171, lower cross bar 18, core accommodating gap 2, upper adjustment plate 3, upper adjustment groove 31, upper adjustment opening 311, lower adjustment plate 4, lower adjustment groove 41, lower adjustment opening 411, etc. are used more in this article, the possibility of using other terms is not excluded.
