Description

Technical Field

[0001] This application relates to the field of electromagnetic chuck application technology, and in particular to a chuck device with storage function. Background Technology

[0002] When lifting electromagnetic chucks using bridge cranes or electric hoists, power is supplied to the chuck via cables. When energized, the chuck generates magnetic attraction, thus attracting and lifting materials. Existing cables are often stored using either a free-flowing method or a cable reel mounted on a trolley. This allows for easy adjustment of cable length, with the cable being retracted or unwound as the electromagnetic chuck moves up and down with the wire rope. However, both methods have drawbacks. Free-flowing storage easily causes friction between the cable and the hook wire rope, leading to damage to the cable's external insulation over time. Furthermore, haphazardly stacked cables are prone to breakage at bends, potentially causing short circuits and explosions. Cable reels have a relatively complex structure. When reeling cables, miswinding or abnormal displacement can occur, preventing normal cable operation. The cable may even detach from the reel's limiting groove and become entangled in the gap between the reel and its bearing support, causing damage. Summary of the Invention

[0003] This utility model aims to solve the problem of cable storage difficulties in the aforementioned electromagnetic chuck, and the technical solution adopted is:

[0004] A suction cup device with a storage function includes an electromagnetic chuck, a storage cylinder detachably connected to the top of the electromagnetic chuck, a conical seat provided in the storage cylinder, the space between the conical seat and the storage cylinder being a cable storage area, the conical seat being used to wind the cable, and the top end of the cable being connected to the lifting trolley of a bridge crane, the bottom end of the cable passing through the storage cylinder to power the electromagnetic chuck; a guide component is provided at the top of the storage cylinder, the guide area in the middle of the guide component being located directly above the conical seat, and when the electromagnetic chuck moves vertically, any inner end face of the guide component is used to roll and abut against the cable.

[0005] Compared with the prior art, the advantages of this utility model, which adopts the above technical solution, are as follows:

[0006] This invention features a storage cylinder on an electromagnetic chuck, which stores the chuck's cable. A conical seat is provided inside the storage cylinder to guide the cable into the cylinder in a coiled manner. A guide component is located at the top of the storage cylinder to limit and guide the cable. The advantage of this rolling guide is that the guide area of ​​the guide component makes rolling contact with the cable, avoiding damage caused by hard friction. Furthermore, the storage cylinder and electromagnetic chuck are detachably connected, allowing for regular cleaning of dust and debris from the storage cylinder and facilitating inspection of the cable's condition.

[0007] As a preferred embodiment, a further technical solution of this utility model is:

[0008] The guiding assembly includes multiple guide brackets mounted on the top of the storage cylinder. Guide rollers are rotatably mounted on the front ends of the guide brackets. All guide rollers are arranged in a ring on the same horizontal plane, with their axial direction perpendicular to the movement direction of the electromagnetic chuck. The center of each guide roller forms a guiding area. The guide brackets support the guide rollers above the top of the storage cylinder. The ring arrangement of the guide rollers creates a guiding area, allowing the cable to potentially contact any of the guide rollers as it moves vertically within the guiding area. The friction causes the cable to rotate, thus limiting the cable's rolling movement.

[0009] The top of the storage cylinder is fixed with the same number of pin seats as the guide brackets. The rear end of the guide bracket is pinned to the pin seats via a pin shaft. A torsion spring is sleeved on the pin shaft. One end of the torsion spring is fixed to the guide bracket, and the other end is fixed to the pin seat. When the torsion spring is in its natural state, the gap between the inner ends of any two adjacent guide rollers is less than the diameter of the cable. The torsion spring limits the setting angle of the guide brackets, so that the guide rollers at the front end of each guide bracket remain in a ring state under the action of the torsion spring, thereby forming a guide area.

[0010] The storage tube has a vertically movable base, and a conical seat is fixed on the base. The outer diameter of the base is equal to the inner diameter of the storage tube. When it is necessary to clean and inspect the cable, the base can be removed from the storage tube, and the conical seat and cable can then be taken out.

[0011] A sliding groove is formed on the inner wall of the storage tube, extending to the top of the storage tube. A sliding block that mates with the sliding groove is fixed to the outer periphery of the base. When the base is located at the bottom of the storage tube, the top of the sliding block extends out of the top of the storage tube. The sliding block can quickly move the base out of the storage tube, thereby bringing out the conical seat and cable on the base.

[0012] The storage tube has a radially fixed limiting block at its bottom, and the electromagnetic chuck has an L-shaped limiting groove in the middle of its top. The limiting block engages with the L-shaped limiting groove. This structure allows the limiting block to move into the L-shaped limiting groove, thus enabling quick connection and disconnection of the storage tube and the electromagnetic chuck.

[0020] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] Reference Figure 1-6This application discloses a suction cup device with a storage function, including an electromagnetic suction cup 1. A storage cylinder 2 is detachably connected to the top of the electromagnetic suction cup 1. A conical seat 22 is provided in the storage cylinder 2. The top diameter of the conical seat 22 is smaller than the bottom diameter. The space between the conical seat 22 and the storage cylinder 2 is a cable 3 storage area. The conical seat 22 is used to wind the cable 3, and the top end of the cable 3 is fixedly connected to the lifting trolley of the bridge crane. A wire hole 27 is provided on the side wall at the bottom of the storage cylinder 2. The bottom end of the cable 3 passes through the wire hole 27 and is inserted into the power supply end of the electromagnetic suction cup 1 to supply power to the electromagnetic suction cup 1. A guide component 21 is provided at the top of the storage cylinder 2. The guide area in the middle of the guide component 21 is located directly above the conical seat 22, and the area of ​​the guide area is smaller than the area of ​​the top of the conical seat 22. When the electromagnetic suction cup 1 moves vertically, any inner end face of the guide component 21 is used to roll and abut against the cable 3.

[0022] In this embodiment, the guiding assembly 21 includes multiple guiding brackets disposed on the top of the storage cylinder 2. A guide roller 213 is rotatably mounted on the front end of each guiding bracket. Pin seats 211, the same number as the guiding brackets, are equidistantly fixed on the top wall of the storage cylinder 2. The rear end of each guiding bracket is pinned to each pin seat 211 via a pin shaft. The guide rollers 213 are arranged in a ring to form a guiding area, and the axial direction of each guide roller 213 is perpendicular to the movement direction of the electromagnetic chuck 1. Specifically, the guiding bracket includes two guide plates 212. A shaft is connected between the front ends of the guide rollers 213, which is movably sleeved on the shaft, allowing the guide rollers 213 to rotate around the shaft. A pin is rotatably inserted into the pin seat 211. The rear ends of the two guide plates 212 of the same guide bracket are respectively fixedly sleeved on the two ends of the corresponding pin, allowing the rear ends of the guide plates 212 to rotate with the pin. A torsion spring is sleeved on the pin between the two ends of the pin seat and the rear ends of the adjacent guide plates 212. One end of the torsion spring is fixed to the guide plate 212, and the other end of the torsion spring is fixed to the pin seat 211. In order to cooperate with the torsion... The rotation of the spring causes the outer bottom of the guide plate 212 to be arc-shaped, while the inner bottom is set with a right-angled edge, allowing the guide plate 212 to flip outward. When the torsion spring is in its natural state, the inner right-angled edge of the guide plate 212 and the axial direction of each guide roller 213 are on the same horizontal plane, and the gap between the inner end roller surfaces of any two adjacent guide rollers 213 is less than the diameter of the cable 3. When the elastic deformation of the torsion spring reaches its limit, the guide bracket is parallel to the axial direction of the storage cylinder 2. The torsion spring limits the setting angle of the guide bracket, so that the guide rollers 213 at the front end of each guide bracket... 3. Under the action of the torsion spring, the cable 3 is kept in a ring state on the same horizontal plane, thus forming a guide area, so that the cable 3 will not move into the gap between the two guide rollers 213; the guide bracket supports the guide rollers 213 above the top of the storage cylinder 2, so that when the cable 3 moves vertically in the guide area, it has a certain probability of contacting any guide roller 213. When in contact, the cable 3 and the guide roller 213 generate friction. Under the action of friction, the cable 3 drives the guide roller 213 to rotate, so that the guide roller 213 limits the rolling of the cable 3.

[0023] In this embodiment, two symmetrical sliding grooves 26 are provided on the inner wall of the storage tube 2. The length of the sliding grooves 26 is equal to the height of the inner wall of the storage tube 2, so that the sliding grooves 26 extend to the top of the storage tube 2. A base 24 is provided in the storage tube 2. A conical seat 22 is fixed on the top surface of the base 24. The outer diameter of the base 24 is equal to the inner diameter of the storage tube 2. Two sliding blocks 25 that cooperate with the sliding grooves 26 are symmetrically fixed on the outer peripheral wall of the base 24. The length of the sliding blocks 25 is set to be equal to the height of the sliding grooves 26, so that when the base 24 is located at the bottom of the storage tube 2, the top of the sliding block 25 extends out of the top of the storage tube 2. A handle 251 is fixed on the top of the sliding block 25. The horizontal area of ​​the handle 251 is larger than the horizontal area of ​​the sliding groove 26, so that the handle 251 abuts against the top of the storage tube 2. When it is necessary to clean and inspect the cable 3, the sliding block is moved up along the sliding groove 26 by the handle 251, which drives the base 24 to be taken out of the storage tube 2, so that the conical seat 22 and the cable 3 on the base 24 can be taken out.

[0024] In this embodiment, a base plate 23 is fixed to the bottom of the storage tube 2. The base plate 23 is cylindrical, and six limiting blocks 231 are fixed at equal intervals on the outer periphery of the base plate 23. A circular groove 12 with the same diameter and height as the base plate 23 is opened in the middle of the top of the electromagnetic chuck 1. Six L-shaped limiting grooves 13 are opened on the electromagnetic chuck 1 around the circular groove 12. The vertical ring length of the L-shaped limiting groove 13 is greater than the ring length of the limiting block 231, and the horizontal height of the L-shaped limiting groove 13 is equal to the height of the limiting block 231. During installation, first align each limiting block 231 at the bottom of the storage tube 2 with the vertical direction of the L-shaped limiting groove 13, press it down to the bottom, and then rotate the storage tube 2. The limiting block 231 rotates into the horizontal side of the L-shaped limiting groove 13, so that the L-shaped limiting groove 13 engages with the limiting block 231, thereby securing the storage tube 2 and the electromagnetic chuck 1, and quickly detaching and connecting the storage tube 2 and the electromagnetic chuck 1.

[0025] In this embodiment, multiple wire rope seats 11 are also fixed to the top of the electromagnetic chuck 1. The wire rope seats 11 are connected to the hook of the crane trolley via wire ropes, so that the hook of the crane trolley drives the electromagnetic chuck 1 to move vertically and adjust the height of the electromagnetic chuck 1. During the first installation, one end of the cable 3 is connected to the power supply and guided to the position of the crane trolley by the guide rail trolley of the bridge crane. The cable 3 is fixed to the crane trolley, so that the length of the cable 3 under the crane trolley is greater than the height of the crane trolley from the ground at this time. Then, the storage tube 2 is installed on the electromagnetic chuck 1, and the cable 3 is passed through the guide assembly 21 and wound onto the conical seat 22. The other end of the cable 3 passes through the wire hole 27 and is connected to the power supply end of the electromagnetic chuck 1, so that the cable 3 hangs naturally and is kept in the center of the storage cylinder 2. The device of this embodiment is suitable for cables 3 with a diameter greater than 30mm. The cable 3 itself has a certain weight. When the operation starts, the electromagnetic chuck 1 is lifted and lowered by the hook of the lifting trolley. When the electromagnetic chuck 1 descends, the cable 3 in the storage cylinder 2 gradually winds out of the conical seat 22. When the electromagnetic chuck 1 rises, the cable 3 moves down under the guidance of the guide roller 213 and contacts the conical surface of the conical seat 22 and coils around the bottom of the conical seat 22, thereby storing the cable 3.

[0026] This invention features a storage cylinder 2 on an electromagnetic chuck 1, through which the cable 3 of the electromagnetic chuck 1 is stored. A conical seat 22 is provided within the storage cylinder 2, guiding the cable 3 into the cylinder in a coiled manner. A guide component 21 is located at the top of the storage cylinder 2, limiting and guiding the cable 3. The advantage of this rolling guidance is that the guiding area of ​​the guide component 21 makes rolling contact with the cable 3, avoiding damage caused by hard friction. Furthermore, the detachable connection between the storage cylinder 2 and the electromagnetic chuck 1 allows for regular cleaning of dust and debris from the storage cylinder 2, and facilitates inspection of the cable 3's condition.

All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
