Description

Technical Field

[0001] The present invention relates to a magnetic attracting mechanism, in particular to a magnetic attracting mechanism with a distribution box. Background Art

[0002] In the recovery of waste iron in some garbage dumps, workers usually need to use a crane and install an electromagnet on the crane boom. By energizing the electromagnet, the waste iron in the recycling station can be adsorbed to achieve a quick collection effect, avoiding the tediousness of manual operation. Moreover, a distribution box is generally placed on the crane now.

[0003] At present, the magnetic attracting mechanism adopted on the crane is relatively simple, which is a circular electromagnet. However, the composition of waste iron in the current garbage dumps is very complex. For example, rust generated by long-term accumulation will be lifted up and easily spread without measures. Secondly, the metals in the garbage are fine and thick, and there are also large and small ones. After a simple electromagnet adsorbs ferromagnetic objects of a certain thickness, the magnetic force below it will become weak, and small things are easily carried by the tiny magnetic force and scattered during the subsequent movement vibration. That is, by changing the structure, the above problems can be minimized, which helps to improve the use effect. Summary of the Invention

[0004] The purpose of the present invention is to provide a magnetic attracting mechanism with a distribution box to solve the problems raised in the above background art.

The housing is a cylindrical structure. The upper end and the lower end of the housing are respectively fixedly connected with the upper cover plate and the lower bottom plate through bolts; An electromagnet fixed on the upper side of the lower bottom plate is arranged inside the housing. The power supply wire of the electromagnet passes through the wire inlet and outlet holes reserved and opened on the upper cover plate and is connected to the output end of the distribution box; A plurality of telescopic pins are installed through pipes on the edge of the electromagnet assembly.

The square flange welded on the outer extension of the lower port of the square tube-shaped bracket is fixedly connected to the upper surface of the lower bottom plate through screws. The upper port of the square tube-shaped bracket passes through the corresponding through hole on the upper cover plate and is also fixedly connected to the end of the telescopic hydraulic cylinder through another square flange welded on the outer extension. The output end of the telescopic hydraulic cylinder is located inside the square tube-shaped bracket and is fixedly connected to the connecting jack opened at the top of the movable pin. A rectangular hollow is axially arranged on the surface of the movable pin. A vertically arranged fixed pull rod is arranged inside the rectangular hollow. The upper end of the fixed pull rod is fixedly connected to the middle of the positioning pin. Both ends of the positioning pin pass through the rectangular hollow and are fixedly inserted into the positioning holes correspondingly opened on the surface of the square tube-shaped bracket. When the output end of the telescopic hydraulic cylinder drives the movable pin to move up and down, the fixed pull rod can move relative to the movable pin inside the rectangular hollow; The lower end of the fixed pull rod is rotatably connected to one end of the cross bar piece through a pin shaft. A chute A is opened on the cross bar piece. The chute A is slidably connected to the sliding shaft. Both ends of the sliding shaft are inserted into the fixed holes correspondingly opened on the movable pin.

[0007] As a further solution of the present invention: A plurality of threaded holes are also opened on the lower surface of the lower bottom plate and are threadedly connected to the stud bolts opened at the tails of the pins. The pins are located in the area between two adjacent flat pipes.

[0008] As a further solution of the present invention: The lower bottom plate is circular, and a plurality of grooves distributed along its axial direction are provided on its upper surface within the range of the outer shell. Through holes penetrating the lower bottom plate are provided at the bottoms of the grooves. The flat tube is inlaid and installed in the grooves of the lower bottom plate. Both ends of the flat tube are sealed, and holes are also opened at positions corresponding to the through holes and circular tubes are welded. The circular tubes of the flat tube are inserted into the corresponding through holes. At the same time, riser insertion holes are opened on the upward-facing side of the flat tube and one end of the riser is connected. The other ends of the risers all pass through the through holes correspondingly opened on the upper cover plate and are connected to the air inlet holes correspondingly opened at the bottom of the annular flat tube located above the upper cover plate. An exhaust hole is opened above the annular flat tube and is connected to a hose.

[0009] As a further solution of the present invention: The adsorption box includes a fixed jaw, a box body, a permanent magnet, a bottom cover, a fixed bracket, a nut, a screw rod, and a movable jaw. The lower end of the fixed jaw is welded to one side of the top of the box body. The fixed jaw is L-shaped. On the other side of the top of the box body at a position corresponding to the fixed jaw, a movable jaw is provided. The middle of the movable jaw is rotationally connected to the surface of the box body through a rotating shaft. The part of the movable jaw above the rotating shaft is also L-shaped, and the upper end of the fixed jaw and the upper end of the movable jaw are oppositely arranged; A chute B is opened in the part of the movable jaw below the rotating shaft. A screw rod is slidably connected in the chute B. One end of the screw rod is hinged to the surface of the box body through a hinge. At the same time, a nut is also threadedly connected to the screw rod between the movable jaw and the surface of the box body; When it is necessary to fix the adsorption box to the robotic arm, rotate the nut towards the box body, so that the movable jaw can rotate at the position of the rotating shaft and can be opened to the maximum angle to clamp onto the robotic arm, and then rotate the nut away from the box body, so that the movement range of the movable jaw is reduced to tightly clamp the robotic arm; An opening is provided below the box body and the bottom cover is connected by bolts. Air inlet and outlet ports are respectively opened on two opposite surfaces of the box body; The surface of the bottom cover facing the inside of the box body is fixedly connected to the fixed bracket through screws, and a permanent magnet is pressed between the fixed bracket and the bottom cover.

[0010] As a further solution of the present invention: A number of parallel ferromagnetic metal adsorption plates are welded on the fixed bracket, and the ferromagnetic metal adsorption plates are perpendicular to the air inlet and outlet ports.

[0011] As a further solution of the present invention: Serrated protrusions can be machined on the edge of the cross bar piece.

[0012] As a further solution of the present invention: When the output end of the telescopic hydraulic cylinder drives the movable peg to rise to the maximum position, the cross bar piece is retracted into the rectangular hollow.

[0013] When adsorbing loose ferromagnetic objects, the electromagnet assembly is pressed down onto the debris. First, manually control to make the output end of the telescopic hydraulic cylinder extend downward by a certain distance, and make the movable peg move downward and prompt the cross bar piece to open.

[0014] When transported to the designated position, manually control the output end of the telescopic hydraulic cylinder to extend downward, which can also prompt the cross bar to retract downward into the rectangular hollow, so as not to affect the release of the object after the electromagnet assembly is powered off.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By setting up a dust suction structure, the present invention can suck a certain amount of air at the operation position. The purpose of this operation is to reduce the scattering of rust powder caused by the rust of ferromagnetic metals. The rusty red powder scattered everywhere also affects the appearance.

[0017] In addition, setting up an adsorption box can prevent the rust iron powder from damaging the filter screen in the vacuum cleaner and avoid shortening the service life of the vacuum cleaner filter screen too much.

[0018] The present invention sets up a stud structure on the electromagnet, which is mainly used to insert into some filamentous or small-sized iron parts to increase the adsorption area, improve the iron absorption effect, and also helps to stabilize the ferromagnetic object after adsorption, reduce the possibility of falling due to movement and vibration, and indirectly enhance its use effect.

Specific implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1 - 3 , in the embodiment of the present invention, an electromagnet mechanism with a distribution box includes an electromagnet assembly 1. The top of the electromagnet assembly 1 is connected to the front end of the robotic arm of the crane 2. The power supply wire of the electromagnet assembly 1 is connected to the power output end of the distribution box fixedly installed on the vehicle body of the crane 2. A dust suction pipeline 4 is arranged in the electromagnet assembly 1. The dust suction port of the dust suction pipeline 4 is located on the lower surface of the electromagnet assembly 1. The output port of the dust suction pipeline 4 is connected to the intake port of the adsorption box 3 through a hose. The air outlet port of the adsorption box 3 is connected to the input end of the vacuum cleaner 6 fixedly installed on the vehicle body of the crane 2. When performing the iron suction operation at the site, especially in places such as construction sites, the air at the operation position can be sucked to a certain extent. The purpose of this operation is to reduce the rust powder scattered everywhere caused by the rust of ferromagnetic metals. The rusty red powder scattered everywhere also affects the beauty.

[0032] The above distribution box is fixedly connected to the vehicle frame on the crane through a metal bracket.

[0033] The electromagnet assembly 1 includes a lower bottom plate 7, a housing 8, an electromagnet 9, and an upper cover plate 10. The housing 8 has a cylindrical structure. The upper and lower ends of the housing 8 are fixedly connected to the upper cover plate 10 and the lower bottom plate 7 by bolts respectively. During actual processing, threaded holes are opened at the ends of the housing 8, and then counterbores corresponding to the threaded holes are opened on the upper cover plate 10 and the lower bottom plate 7. Finally, the three are connected by bolts. Among them, the material of the lower bottom plate 7 is ferromagnetic metal, while the housing 8, the electromagnet 9, and the upper cover plate 10 can be any strong metal material. The electromagnet 9 fixed on the upper side of the lower bottom plate 7 is arranged inside the housing 8. The power supply wire of the electromagnet 9 passes through the wire inlet and outlet holes reserved on the upper cover plate 10 and is connected to the output end of the distribution box.

[0034] The lower bottom plate 7 is circular, and a plurality of grooves distributed along its axial direction are opened on its upper surface within the range of the housing 8. Through holes penetrating the lower bottom plate 7 are opened at the bottoms of the grooves. The flat tube 15 is inlaid and installed in the grooves of the lower bottom plate 7. Both ends of the flat tube 15 are sealed, and holes are also opened at positions corresponding to the through holes and welded with round tubes 16. The round tubes of the flat tube 15 are inserted into the corresponding through holes. At the same time, a riser jack 14 is opened on the upward-facing side of the flat tube 15 and connected to one end of the riser 13. The other ends of the risers 13 all pass through the through holes correspondingly opened on the upper cover plate 10 and are connected to the air inlet holes correspondingly opened at the bottom of the annular flat tube 11 located above the upper cover plate. An exhaust hole is opened above the annular flat tube 11 and connected to a hose. When the vacuum cleaner works, negative pressure will be generated at the lower end of the flat tube 15 to adsorb the surrounding air containing dust. The air with dust passes through the round tube 16, the flat tube 15, and the riser 13, and after converging in the annular flat tube 11, it enters the hose connected to the vacuum cleaner through the flat tube exhaust hole 12, thereby achieving the effect of dust reduction.

[0035] The adsorption box 3 includes a fixed clamping jaw 29, a box body 30, a ferromagnetic metal adsorption plate 31, a permanent magnet 32, a bottom cover 33, a fixed bracket 34, a nut 35, a screw 36, a slide groove B37 and a movable clamping jaw 38. The lower end of the fixed clamping jaw 29 is welded to one side of the top of the box body 30, and the fixed clamping jaw 29 is L-shaped. The movable clamping jaw 38 is arranged at a position corresponding to the fixed clamping jaw 29 on the other side of the top of the box body 30. The middle of the movable clamping jaw 38 is rotatably connected to the surface of the box body 30 through a rotating shaft. The part of the movable clamping jaw 38 located above the rotating shaft is also L-shaped, and the upper end of the fixed clamping jaw 29 is arranged opposite to the upper end of the movable clamping jaw 38, and the distance between the two is equal to the thickness of the mechanical arm profile of the crane 2, so as to facilitate clamping on the mechanical arm; The movable clamping jaw 38 is provided with a slide groove B37 at the part below the rotating shaft, and a screw rod 36 is slidably connected in the slide groove B37. One end of the screw rod 36 is hinged to the surface of the box body 30 through a hinge, and a nut 35 is also threadedly connected to the screw rod 36 between the movable clamping jaw 38 and the surface of the box body 30; when it is necessary to fix the adsorption box 3 to the mechanical arm (the cross section is generally similar to an I-shaped), the nut is rotated toward the box body so that the movable clamping jaw 38 can rotate at the rotating shaft position and can be opened to the maximum angle to clamp the mechanical arm, and then the nut is rotated away from the box body so that the movable range of the movable clamping jaw is reduced to clamp the mechanical arm tightly. If necessary, a wrench is used to further tighten it, and disassembly only requires reverse operation;

[0036] The bottom of the box body 30 is provided with an opening and a bottom cover 33 is connected by bolts. An air inlet and an air outlet (for connecting a corresponding hose connected to the vacuum cleaner) are respectively provided on two opposite surfaces of the box body 30. The surface of the bottom cover 33 facing the inside of the box body is fixedly connected to a fixing bracket 34 by screws, and a permanent magnet 32 ​​is pressed against the fixing bracket 34 and the bottom cover 33. The permanent magnet 32 ​​is preferably a neodymium iron boron magnet with strong enough magnetism. A plurality of parallel ferromagnetic metal adsorption plates 31 are welded on the fixing bracket 34, and the ferromagnetic metal adsorption plates 31 are arranged perpendicular to the air inlet and the air outlet. During the flow of air, the air flow with iron powder flows between the two ferromagnetic metal adsorption plates 31, which can cause the iron powder or magnetic powder mixed inside to be adsorbed. In addition, after the high-speed air flow at the air inlet enters the box body, the internal flow velocity becomes relatively slow due to the increase in the cross-sectional area, which makes adsorption easier and is conducive to precipitation. In addition, the cross-sectional area of ​​the air outlet is equal to the cross-sectional area of ​​the air inlet, which does not cause the flow velocity in the hose to change, that is, it does not affect the dust collection effect of the rated design. The purpose of using an adsorption box in this solution is to prevent rust and iron powder from damaging the filter in the vacuum cleaner and shortening the life of the filter too much.

[0037] The lower surface of the lower base plate 7 is also provided with a plurality of threaded holes and is threadedly connected to the studs provided at the tails of the plug pins 39. The plug pins can be selectively used and are mainly used for inserting into some filamentous or small-sized iron parts to increase the adsorption area, improve the iron absorption effect, and also help to stabilize the ferromagnetic objects after adsorption and reduce the possibility of falling due to movement and vibration.

[0038] The area where the plug pin 39 is located between two adjacent flat tubes.

[0039] The plug pins can also be used to comb the underlying garbage, increase the iron searching effect, and facilitate the flow of the dispersed soil blocks.

[0040] Embodiment 2

[0041] As Figures 4 - 9 , a plurality of telescopic plug pins are installed through pipes on the edge of the electromagnet assembly 1 (it is sufficient that there is a space for installing the telescopic plug pins between the internal electromagnet 9 and the inner wall of the housing), and the telescopic plug pins and the flat tubes 15 are arranged alternately around the axis of the electromagnet assembly 1; the telescopic plug pins include a cross bar piece 17, a fixed pull rod 18, a positioning pin 19, a movable plug pin 20, a square tube-shaped bracket 21, a telescopic hydraulic cylinder 22, a sliding shaft 23, a chute A24, a serrated protrusion 25, a connection jack 26, a rectangular hollow 27, and a tip 28.

[0042] The square flange welded to the outer extension of the lower port of the square tube-shaped bracket 21 is fixedly connected to the upper surface of the lower base plate 7 by screws. The upper port of the square tube-shaped bracket 21 passes through the corresponding through holes on the upper cover plate and is also fixedly connected to the end of the telescopic hydraulic cylinder 22 by another square flange welded to the outer extension. The output end of the telescopic hydraulic cylinder 22 is located inside the square tube-shaped bracket 21 and is fixedly connected to the connection jack 26 provided at the top of the movable plug pin 20 (in fact, the output end of the telescopic hydraulic cylinder 22 is processed into a bolt and passes through the connection jack 26, and then is threadedly connected to the lower screw cap). A rectangular hollow 27 is axially provided on the surface of the movable plug pin 20, and a vertically arranged fixed pull rod 18 is arranged inside the rectangular hollow 27. The upper end of the fixed pull rod 18 is fixedly connected to the middle of the positioning pin 19. Both ends of the positioning pin 19 pass through the rectangular hollow 27 and are fixedly inserted into the positioning holes correspondingly provided on the surface of the square tube-shaped bracket 21. When the output end of the telescopic hydraulic cylinder 22 drives the movable plug pin 20 to move up and down, the fixed pull rod 18 can move relative to the movable plug pin 20 inside the rectangular hollow 27.

[0043] The above-mentioned telescopic hydraulic cylinder 22 is controlled by a separate hydraulic system, and its control method and installation position can adopt the common knowledge of technicians in the field.

[0044] The lower end of the fixed pull rod 18 is rotatably connected to one end of the cross bar piece 17 through a pin shaft. A chute A24 is formed in the upper part of the cross bar piece 17, and the chute A24 is slidably connected to the sliding shaft 23. Both ends of the sliding shaft 23 are inserted into the fixing holes correspondingly formed in the movable plug 20. The edge of the cross bar piece 17 can be processed with serrated protrusions 25.

[0045] As Figure 8 , when the output end of the telescopic hydraulic cylinder 22 drives the movable plug 20 to rise to the maximum position, the cross bar piece 17 is received into the rectangular hollow 27;

[0046] As Figure 4 , when adsorbing loose ferromagnetic objects, the electromagnet assembly 1 is pressed down onto the sundries. First, manual control can be used to make the output end of the telescopic hydraulic cylinder 22 extend downward by a certain length, and make the movable plug 20 move downward to prompt the cross bar piece 17 to open. At this time, under the action of material elasticity and some other factors, a part of the ferromagnetic objects can be supported by the cross bar piece 17, improving stability;

[0047] As Figure 9 , when transported to the designated position, manual further control is used to make the output end of the telescopic hydraulic cylinder 22 extend downward, and it can also prompt the cross bar piece 17 to be received downward into the rectangular hollow 27 so as not to affect the dropping of the object after the electromagnet assembly 1 is powered off.

[0048] By designing the telescopic plug, more adsorption environments can be dealt with, and the cooperation of the opening and closing of the cross bar piece 17 can also improve the stability of transportation.

[0049] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

Air inlet and outlet ports are respectively formed on two opposite surfaces of the box body (30); the surface of the bottom cover (33) facing the inside of the box body is fixedly connected to the fixing bracket (34) through screws, and a permanent magnet (32) is pressed between the fixing bracket (34) and the bottom cover (33).

5. The electromagnet mechanism with a distribution box according to claim 4, characterized in that, A plurality of parallel ferromagnetic metal adsorption plates (31) are welded on the fixed bracket (34), and the ferromagnetic metal adsorption plates (31) are arranged perpendicular to the air inlet and the air outlet.

6. The iron absorption mechanism with a distribution box according to claim 1, characterized in that, Jagged protrusions (25) are processed on the edge of the cross bar piece (17).

7. The iron absorption mechanism with a distribution box according to claim 6, characterized in that, When the output end of the telescopic hydraulic cylinder (22) drives the movable peg (20) to rise to the maximum position, the cross bar piece (17) is received into the rectangular hollow (27); When adsorbing loose ferromagnetic objects, the electromagnet assembly (1) presses down on the sundries. First, manually control the output end of the telescopic hydraulic cylinder (22) to extend downward by a certain distance, and make the movable peg (20) move downward to promote the cross bar piece (17) to open; When transported to the designated position, manually control the output end of the telescopic hydraulic cylinder (22) to extend downward, which also promotes the cross bar piece (17) to be received downward into the rectangular hollow (27) so as not to affect the release of the object after the electromagnet assembly (1) is powered off.
