Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic cranes, in particular to an integrated multifunctional electromagnetic crane hanging beam sling. Background Art

[0002] In the prior art, hanging beam (crossbeam) hoisting equipment is widely used in steel mills, ports, mines and other hoisting occasions of lifting machinery. According to the different shapes of objects, the design of hanging beams is diverse. When combined with the crane hook assembly, it can realize the lifting of larger objects, providing a safe and convenient lifting method for enterprises to lift large objects. It has now been applied to various fields of crane lifting. The integrated electromagnetic disk hanging beam hoist of the crane is mainly used in the electromagnetic bridge crane picking and hanging device of the steel plant, which is carried out by hanging the electromagnetic disk. For example: in the use occasions such as lifting of steel billets, suction and transportation of scrap steel, and suction and transportation of steel slag, it suspends double electromagnetic disks or multiple electromagnetic disks, and transmits power through the natural vertical rise and fall movement of the cable drum, so as to realize the function of continuously supplying power to the electromagnetic disk to absorb objects.

[0003] The hanging beams of electromagnetic bridge cranes all suspend electromagnetic disks through hanging beams, rely on cables to transmit power, and supply electromagnetic disks for use in order to achieve the suction and transportation of various iron objects. In the currently known field, cable reels, cables, hanging beams and electromagnetic disks are commonly used. Each configuration is a single component, which needs to be installed and assembled one by one on site and connected to each other with cables. The disadvantage is that the electromagnetic disk chain is an easily worn part, and the length of the main ring of the newly purchased chain often deviates, making the chain length different, resulting in uneven bottom surfaces of the two suspended electromagnetic disks, which affects the efficiency of the electromagnetic disk in absorbing materials, and the hanging beam body does not have an adjustable function. An electromagnetic crane cable winding device has been disclosed, with patent number 200920152929.0 and publication date 2010.03.10. It has a cable basket fixed on the hanging beam of the electromagnetic crane, and a cable basket is provided in the middle of the hanging beam of the hanger connecting the two electromagnetic disks. The cable basket is composed of a box body and a cone set. The box body is cylindrical, and a cone is provided in the center of the box body. There is a space for winding the cable between the box body and the cone. When the electromagnetic disk rises, it is guided by the cone surface of the cone, and the cable can be naturally wound in the box body. The disadvantage is that the cable basket is connected in the middle of the hanging beam and suspended on both sides of the electromagnetic disk, and the connection is easy to deform and damage.

It is characterized in that the electromagnetic disk hanging beam is V-shaped, with a platform at the bottom of the V-shaped, a cable holding cylinder is seated on the platform, and the inner bottom of the cable holding cylinder is a convex conical panel; the cable holding cylinder is surrounded by a square cylindrical protective plate, and the bottom of the square cylindrical protective plate is welded with spaced reinforcing ribs on both sides of the bottom surface and welded to the side of the electromagnetic disk hanging beam at the same time; there are cable outlets on both sides of the lower part of the square cylindrical protective plate; there are hook group hanging beam pin shaft holes on both ends of the electromagnetic disk hanging beam, and there are adjustable pin shaft holes for inserting adjustable pin shafts under both ends of the electromagnetic disk hanging beam. The adjustable pin shaft includes a horizontal axis, one end of the horizontal axis has an eccentric boss, an eccentric locking flange and an eccentric adjustment square shaft head connected in sequence, and the other end of the horizontal axis also has an eccentric boss.

[0006] The above scheme also includes:

[0007] Both sides of the electromagnetic disk hanging beam are provided with reinforcement guard plates, and the reinforcement guard plates are provided with cable fixing buckles.

[0017] See also Figure 1 -6. The names of the parts are as follows: electromagnetic disk hanging beam 1, reinforcement plate 2, square cylindrical protective plate 3, cable holding cylinder 4, conical panel 5, hook group hanging beam pin shaft hole seat 6, lifting chain 7, reinforcement guard plate 8, electromagnetic disk 9, adjustable pin shaft hole seat 10, cable 11, reinforcement rib plate 12, cable fixing buckle 13, cable outlet 14, eccentric adjustment square shaft head 15, horizontal axis 16, eccentric locking flange 17, eccentric boss 18, trolley junction box 19, trolley platform 20.

[0018] See also Figure 1 -6, integrated multifunctional electromagnetic crane hanging beam sling, including electromagnetic disk hanging beam 1, electromagnetic disk hanging beam 1 is connected with electromagnetic disk 9 by hanging chain 7 at both ends, and external cable 11 is connected with electromagnetic disk 9 for power supply. Electromagnetic disk hanging beam 1 is V-shaped, with a platform at the bottom of the V-shape, and a fixed cable containing cylinder 4 for containing cables is connected on the platform, and the inner bottom of the cable containing cylinder 4 is a convex conical panel 5, and the function of the conical panel 5 is to allow the naturally hanging cable 11 to fall into the barrel in an orderly manner by itself, so as to avoid the shaking of the cable suspended in the air during the operation and movement of the crane trolley. When the mechanism is lowered and dropped, the cable cannot enter the barrel in an orderly manner due to shaking, causing the cable to hang outside the barrel, causing scratches and damage. It is more convenient to arrange and stack the cables in sequence when they are freely dropped, without human intervention, and the cable connectors are all connected in the cable barrel at one time, which increases the operating stability and is more practical. Taking into account the possible damage to the cable holding cylinder 4, the electromagnetic disk hanging beam 1 and accessories caused by scratches, collisions or scratches with messy objects on the ground due to careless human operation and the high temperature of the surrounding environment, the cable holding cylinder 4 is directly provided with a square cylindrical protective plate 3 and a reinforcing plate 2, a reinforcing guard plate 8 and a reinforcing rib plate 12 for strengthening the overall structure, which are welded and manufactured in one piece. Specifically, the cable holding cylinder 4 is surrounded by a square cylindrical protective plate 3 to protect the cable holding cylinder 4 in the square frame. The two sides of the bottom surface of the square cylindrical protective plate 3 are welded with reinforcing rib plates 12 that are spaced apart and welded to the sides of the electromagnetic disk hanging beam 1 at the same time, reinforcing the bottom to strengthen the overall strength of the main hanging beam. The two sides of the square cylindrical protective plate 3 are respectively connected with reinforcing plates 2. There are cable outlets 14 on both sides of the lower part of the square cylindrical protective plate 3.

[0019] The two sides of the electromagnetic disk hanging beam 1 are provided with reinforcement plates 8, and the reinforcement plates 8 are provided with cable fixing buckles 13, so that the cables are laid in an orderly and regular manner and are not easy to shake or be scratched by external foreign objects. The two ends of the electromagnetic disk hanging beam 1 are provided with hook group hanging beam pin shaft hole seats 6.

[0020] See also Figure 1 , 2 3. Adjustable pin holes 10 are provided under both ends of the electromagnetic disk hanging beam 1. Adjustable pin holes 10 for inserting adjustable pins are provided under both ends of the electromagnetic disk hanging beam 1. All parts are welded to the electromagnetic disk hanging beam 1. The adjustable pin (or eccentric pin) includes a transverse axis 16. One end of the transverse axis 16 has an eccentric boss 18, an eccentric locking flange 17 and an eccentric adjustment square shaft head 15 connected in sequence, and the eccentric distance is e. The other end of the transverse axis 16 also has an eccentric boss 18. The eccentric locking flange 17 is used to lock the rotating eccentric pin after adjustment to prohibit it from moving or rotating. The adjustable pin is used to suspend the main ring of the hanging chain 7, and the length of the suspended electromagnetic disk chain can be adjusted to achieve the height adjustment of the electromagnetic disk suspension. The pin is made of Cr2O3, which has good resistance to high temperature, high steam, corrosion, etc. on site, and has high strength and wear resistance. The main beams on both sides of the electromagnetic disk hanging beam 1 are moved up, and the height is kept at the same level as the middle of the cable containing cylinder 4. The purpose of moving the height up is to install an adjustable pin shaft hole seat 10 in the cavity of the reinforcement guard plate 8 reinforced at the bottom thereof. Because the hanging chain 7 of the electromagnetic disk 9 is easy to wear out during long-term use, when replacing, the hanging chain 7 will have a certain size deviation due to the factory processing and production when purchasing spare parts, resulting in different lengths of the hanging chain. After the electromagnetic disk 9 is installed, the bottom surfaces of the two electromagnetic disks of the electromagnetic disk 9 will be uneven, thus affecting the efficiency of the electromagnetic disk 9 in absorbing objects and the firmness of adsorption. In the cavity of the reinforcement guard plate 8, an eccentric shaft hanging mechanism is installed, which can make slight adjustments to the height of the electromagnetic disk 9 to adjust the height of the two electromagnetic disks 9 to keep them flush.

[0021] Adjustment method: Before adjustment, drop the electromagnetic disk 9 to the ground to reduce the weight of the electromagnetic disk 9 chain, and then rotate it with a wrench. Figure 2 The square shaft head 15 is adjusted eccentrically. At this time, the eccentric shaft rotates. When the horizontal shaft 16 rotates to make the protruding shaft face upward, the hanging chain 7 of the electromagnetic disk 9 can be driven to move upward; on the contrary, when it is downward, the horizontal shaft 16 rotates to make the protruding shaft face downward, and the hanging chain 7 of the electromagnetic disk 9 can be moved downward, so that the height of the bottom surface of the electromagnetic disk 9 can be adjusted. After the bottom of the electromagnetic disk 9 is adjusted to be flush, the eccentric locking flange 17 is installed in conjunction with the head end of the hanging beam, and each screw is tightened with a socket wrench.

[0022] See also Figure 1Working principle: When the electromagnetic disk 9 is rising, the cable 11 powered by the electromagnetic disk 9 is naturally and orderly coiled around the cone of the conical panel 5 in the cable containing cylinder 4 by its own drooping gravity. When the electromagnetic disk 9 is descending, the cable 11 powered by the electromagnetic disk is naturally stretched and released, and with the forward and reverse movements of the winch motor mechanism, a working cycle is completed reciprocatingly.

[0023] Since this set of slings and their cables were put into use on site, they have rarely failed and are basically maintenance-free. All components can reach their normal service life cycle, so their failure rate is extremely low, saving manpower maintenance and the cost of purchasing spare parts for the sling beams, significantly reducing the downtime of equipment and enabling the equipment to better serve production.

[0024] The above description is only a specific implementation of the present utility model, and various examples do not constitute a limitation on the essential content of the present utility model.
