An automatic feeding overhead crane device

Abstract

This invention discloses an automatic feeding overhead crane device, relating to the technical field of feeding devices. It includes a feeding box with two material pipe assemblies at its bottom. Each material pipe assembly includes a discharge pipe, the lower end of which is rotatably connected to a guide pipe. In this invention, a winch operates to unwind a wire rope. Under the weight of the corrugated material pipe itself, a lifting disc slides downwards along the guide pipe until the pipe bend aligns with the feeding port, thus feeding the production equipment. To ensure the accuracy of the pipe bend's alignment with the processing equipment's inlet, a rotary motor drives a gear to rotate, which, in conjunction with a gear ring, rotates the guide pipe. Because the guide pipe has multiple raised sliding strips around its perimeter, and the guide ring has multiple sliding grooves on its inner side that engage with and slidably connect to the sliding strips, the rotation of the guide pipe drives the rotation of the corrugated material pipe and the pipe bend, thereby adjusting the orientation of the pipe bend to ensure accurate feeding.

Description

Technical Field

[0001] This invention relates specifically to the field of feeding device technology, and more specifically to an automatic feeding overhead crane device. Background Technology

[0002] Overhead crane feeding systems are widely used material conveying and adding devices in industrial production and other fields. They are also widely used in the chemical industry, where various chemical raw materials are added to reactors, such as monomers and initiators, to polymerization reactors.

[0003] In the chemical industry, traditional overhead crane feeding involves using the crane's hook to lift the material package and then hoist the raw material to the equipment where it needs to be added. The material is then added by making a cut with a knife.

[0004] In the chemical industry, the feeding of materials requires precise control. The above-mentioned feeding method requires hoisting operations across equipment, which is extremely dangerous. Furthermore, the materials are not easy to control when adding them, and it is impossible to accurately add the materials to the production equipment; in particular, the height of the feeding mechanism is not easy to control. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic feeding overhead crane device. The feeding bin can store various materials, and the materials can be precisely added to the production equipment via the feeding pipe. The amount of material added is easily controlled, and the feeding process requires no manual intervention, greatly reducing the risks associated with lifting across equipment. This addresses the technical problems mentioned in the background section.

[0008] The lifting plate is connected to a steel wire rope via a U-shaped buckle, and the upper end of the steel wire rope is connected to a winch; the winch is fixedly installed on a fixed platform, which is welded to the feed pipe by multiple ribs.

[0009] A rotary motor is also fixed on the fixed platform. The output shaft of the rotary motor passes through the bottom of the fixed platform and is fitted with a gear. The gear meshes with a gear ring, which is fitted on the upper end of the guide tube.

[0010] As a further technical solution of the present invention, the feeding box has a partition inside, and the two sides of the partition are material storage chambers; the bottom of each storage chamber is conical and is fitted with a material pipe assembly; and a feeding port is provided at the top of each storage chamber.

[0011] As a further technical solution of the present invention, the guide tube is provided with a plurality of raised slide bars around its perimeter; the inner side of the guide ring is provided with a plurality of slide grooves that cooperate with and slide in connection with the slide bars.

[0012] As a further technical solution of the present invention, the feeding box is fixedly installed on the traveling trolley, and the traveling trolley is provided with guardrails on both sides.

[0013] A maintenance platform is provided below the traveling trolley, which is fixedly connected to the traveling trolley by multiple C-shaped steel beams.

[0014] As a further technical solution of the present invention, the traveling wheels on both sides of the traveling trolley travel on the tracks on the main beam and the secondary beam respectively; the two ends of the main beam and the secondary beam are fixedly installed on the end beam trolley.

[0015] A guardrail is fixedly installed on the outer side of the main beam, and a control room is located on the inner side of the guardrail. The control room is fixed on the main beam.

[0016] As a further technical solution of the present invention, a cyclone centrifuge is provided on each side of the feeding box. The air inlet of the cyclone centrifuge is connected to the upper end of the feeding box, and the bottom port of the cyclone centrifuge is connected to the lower end of the feeding box through a pipe. A centrifugal fan is connected to the air outlet at the top of the cyclone centrifuge.

[0017] As a further technical solution of the present invention, the upper end and the lower end of one side of the feeding box are respectively threaded with an upper material level sensor and a lower material level sensor; the probes of the upper material level sensor and the lower material level sensor extend into the storage cavity inside the feeding box;

[0018] The material level sensor is electrically connected to the full material warning light; the material level sensor is electrically connected to the low material warning light; the full material warning light and the low material warning light are fixed on the guardrail on the outside of the traveling trolley, with the full material warning light located above the low material warning light.

[0019] As a further technical solution of the present invention, a limit switch is fixedly installed at the bottom of the fixed platform, and the movable contact of the limit switch is located below the gear ring and the gear.

[0020] As a further technical solution of the present invention, a feeding valve is fixedly installed on the top of the feeding pipe; the upper end of the feeding valve is fixedly connected to the feeding box; the feeding valve is a ZXF-01CS pneumatic bell-type feeding valve.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the winch operates to unwind the wire rope, and under the weight of the corrugated tube itself, it drives the lifting plate to slide down along the guide tube until the bend of the tube is aligned with the feeding port, thereby realizing the feeding of the production equipment;

[0023] 2. In this invention, to ensure the accuracy of the material pipe elbow and the material inlet of the processing equipment, a rotary motor drives a gear to rotate, which, in conjunction with a gear ring, enables the rotation of the guide pipe. Because the guide pipe has multiple raised sliding strips around its perimeter, and the guide ring has multiple sliding grooves on its inner side that engage with and slidably connect to the sliding strips, the rotation of the guide pipe can drive the rotation of the corrugated pipe and the material pipe elbow, thereby adjusting the orientation of the material pipe elbow to ensure accurate material feeding.

[0024] 3. In this invention, when feeding material into the feeding box, the centrifugal fan is turned on. When the material is filled into the feeding box, it will squeeze the internal air outward. The air mixed with the material is drawn into the cyclone centrifuge by the centrifugal fan. Under the action of the cyclone centrifuge, the material settles downward and re-enters the feeding box, while the clean air is drawn out by the centrifugal fan, thereby avoiding the backflow of material during feeding and greatly improving the cleanliness of the work site.

[0025] 4. In this invention, during material feeding, the material level sensor senses the material. When the material level reaches a certain level, the material level sensor is detected and transmits a photoelectric signal to the full warning light. At this time, the full warning light lights up, and the feeding device can be stopped.

[0026] 5. In this invention, when feeding materials into the production equipment, if the material level is low and the feeding level sensor cannot detect the material level, the feeding level sensor will transmit a photoelectric signal to the material shortage warning light, at which time the material shortage warning light will light up to remind the staff to add materials to the feeding box.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 10In this embodiment of the invention, an automatic feeding overhead crane device includes a feeding box 1, with two material pipe assemblies 2 at the bottom of the feeding box 1; each material pipe assembly 2 includes a discharge pipe 21, the lower end of which is rotatably connected to a guide pipe 27; the lower end of the guide pipe 27 is slidably connected to a guide ring, and a corrugated material pipe 26 is fixed to the outside of the guide ring by a clamp 212; a lifting plate 25 is installed at the upper end of the corrugated material pipe 26 in cooperation with a rotating ring 211; and a material pipe elbow 213 is fixedly installed at the bottom of the corrugated material pipe 26 by a clamp 212.

[0041] The lifting plate 25 is connected to a steel wire rope 24 via a U-shaped buckle. The upper end of the steel wire rope 24 is connected to the winch 23. The winch 23 is fixedly installed on a fixed platform 22, which is welded to the feed pipe 21 by multiple ribs.

[0042] By adopting the above technical solution, when in use, the materials to be added are transported to the feeding box 1 by the pneumatic conveyor for storage. When it is necessary to add materials, the trolley is moved to the designated position, and the corresponding material pipe assembly 2 is selected according to the materials to be added for feeding.

[0043] When the winch 23 is activated, it unwinds the wire rope 24. Under the weight of the corrugated tube 26, it drives the lifting plate 25 to slide down along the guide tube 27 until the tube bend 213 is aligned with the feeding port, thereby realizing the feeding of the production equipment.

[0044] More specifically, a rotary motor 210 is also fixed on the fixed platform 22. The output shaft of the rotary motor 210 extends through the bottom of the fixed platform 22 and is fitted with a gear 29. The gear 29 meshes with a gear ring 28, which is fitted on the upper end of the guide tube 27.

[0045] By adopting the above technical solution, during material feeding, in order to ensure the accuracy of the material pipe elbow 213 and the material inlet of the processing equipment, the rotary motor 210 drives the gear 29 to rotate, and with the cooperation of the gear ring 28, the guide material pipe 27 is rotated. Since the guide material pipe 27 is provided with multiple raised sliding strips around its perimeter, and multiple sliding grooves that cooperate with and slide with the sliding strips are opened on the inner side of the guide ring, the rotation of the guide material pipe 27 can drive the rotation of the corrugated material pipe 26 and the material pipe elbow 213, thereby realizing the orientation adjustment of the material pipe elbow 213 to ensure the accuracy of material feeding;

[0046] In addition, since the lifting plate 25 is rotatably connected to the corrugated tube 26 through the rotating ring 211, the lifting and rotating actions of the entire tube assembly 2 do not interfere with each other; thereby improving the mobility and flexibility of the tube assembly 2 in unloading.

[0047] In this embodiment, the feeding box 1 has a partition inside, and the two sides of the partition are material storage chambers; the bottom of each storage chamber is conical and is fitted with a material pipe assembly 2; each storage chamber is provided with a feeding port 5 at the top.

[0048] By adopting the above technical solution, two types of materials can be stored, and when adding materials, the materials that need to be added can be selected as needed.

[0049] In this embodiment, the feeding box 1 is fixedly installed on the traveling trolley 10, and the traveling trolley 10 is provided with guardrails on both sides.

[0050] A maintenance platform 11 is provided below the traveling trolley 10. The maintenance platform 11 is fixedly connected to the traveling trolley 10 by multiple C-shaped steel beams.

[0051] By adopting the above technical solutions, the lubrication of the wire rope and the maintenance and repair of the equipment are facilitated, and the guardrails provide protection for maintenance personnel.

[0052] In this embodiment, the traveling wheels on both sides of the traveling trolley 10 travel on the tracks on the main beam 12 and the secondary beam 14 respectively; the two ends of the main beam 12 and the secondary beam 14 are fixedly installed on the end beam trolley 15.

[0053] A guardrail 13 is fixedly installed on the outer side of the main beam 12, and a control room 16 is provided on the inner side of the guardrail 13. The control room 16 is fixed on the main beam 12.

[0054] By adopting the above technical solution, the traveling trolley 10 can move along the tracks on the main beam 12 and the secondary beam 14; the end beam trolley 15 moves along the slide rails on both sides of the factory building, thereby realizing the movement of the entire trolley so as to add and unload materials from the feeding box 1.

[0055] In this embodiment, a cyclone centrifuge 3 is provided on each side of the feeding box 1. The air inlet of the cyclone centrifuge 3 is connected to the upper end of the feeding box 1, and the bottom port of the cyclone centrifuge 3 is connected to the lower end of the feeding box 1 through a pipe. A centrifugal fan 4 is connected to the air outlet at the top of the cyclone centrifuge 3.

[0056] Because the gas material conveyor will produce some gas when conveying materials, when the material and gas mixture enter the feeding box 1, backflow will occur, resulting in powder spreading during feeding and a large amount of material being wasted.

[0057] By adopting the above technical solution, when feeding material into the feeding box 1, the centrifugal fan 4 is turned on. When the material is filled into the feeding box 1, it will squeeze the internal air outward. The air in the mixture is drawn into the cyclone centrifuge 3 by the centrifugal fan 4. Under the action of the cyclone centrifuge 3, the material settles downward and re-enters the feeding box 1, while the clean air is drawn out by the centrifugal fan 4, thereby avoiding the backflow of material during feeding and greatly improving the cleanliness of the work site.

[0058] In this embodiment, the upper end and lower end of one side of the feeding box 1 are respectively threaded with an upper material level sensor 6 and a lower material level sensor 7; the probes of the upper material level sensor 6 and the lower material level sensor 7 extend into the storage cavity inside the feeding box 1.

[0059] The material level sensor 6 is electrically connected to the full material warning light 8; the material level sensor 7 is electrically connected to the low material warning light 9; the full material warning light 8 and the low material warning light 9 are fixed on the guardrail outside the traveling trolley 10, with the full material warning light 8 located above the low material warning light 9.

[0060] By adopting the above technical solution, when feeding, the feeding level sensor 6 senses the material. When the material level reaches a certain level, the feeding level sensor 6 is sensed and transmits the photoelectric signal to the full warning light 8. At this time, the full warning light 8 lights up, and the feeding device can be stopped.

[0061] When feeding materials into the production equipment, if the material level is low and the feeding level sensor 7 cannot detect the material level, the feeding level sensor 7 will transmit a photoelectric signal to the material shortage warning light 9. At this time, the material shortage warning light 9 will light up to remind the staff to add materials to the feeding box 1.

[0062] In this embodiment, a limit switch 214 is fixedly installed at the bottom of the fixed platform 22, and the movable contact of the limit switch 214 is located below the toothed ring 28 and the gear 29.

[0063] By adopting the above technical solution, the limit switch 214 can limit the rise of the corrugated tube 26, avoid excessive rise and overshooting, and prevent the lifting plate 25 from colliding with the toothed ring 28.

[0064] In this embodiment, a discharge valve 215 is fixedly installed on the top of the discharge pipe 21; the upper end of the discharge valve 215 is fixedly connected to the feeding box 1; the discharge valve 215 is a ZXF-01CS pneumatic bell-shaped discharge valve.

[0065] The setting of the feeding valve 215 greatly facilitates the opening and closing control during feeding.

[0066] The working principle is as follows: During use, the materials to be added are transported to the feeding box 1 by a pneumatic conveyor. Since the pneumatic material conveyor produces some gas when transporting materials, when the material and gas mixture enters the feeding box 1, backflow can occur, resulting in powder dispersion during feeding and a large amount of material being wasted. To address this, when adding materials to the feeding box 1, the centrifugal fan 4 is turned on. As the material fills the feeding box 1, it compresses the internal air outward. The air mixed with the material is drawn into the cyclone centrifuge 3 by the centrifugal fan 4. Under the action of the cyclone centrifuge 3, the material settles downward and re-enters the feeding box 1, while the clean air is drawn out by the centrifugal fan 4, thus preventing backflow during feeding and greatly improving the cleanliness of the work site. The feeding level sensor 6 senses the material. When the material level reaches a certain level, the feeding level sensor 6 is detected and transmits a photoelectric signal to the full warning light 8. At this time, the full warning light 8 lights up, and the feeding device can be stopped.

[0067] When material needs to be added, the overhead crane is moved to the designated position, and the corresponding material tube assembly 2 is selected according to the material to be added for feeding. The winch 23 is activated to unwind the wire rope 24. Under the weight of the corrugated material tube 26, the lifting plate 25 is driven to slide down along the guide material tube 27 until the material tube bend 213 is aligned with the feeding port, thereby realizing the feeding of the production equipment.

[0068] During feeding, to ensure the accuracy of the material pipe elbow 213 and the material inlet of the processing equipment, the rotary motor 210 drives the gear 29 to rotate, which, in conjunction with the gear ring 28, enables the rotation of the guide pipe 27. Since the guide pipe 27 has multiple raised sliding strips around its perimeter, and the guide ring has multiple sliding grooves that engage with and slide on the inner side of the strips, the rotation of the guide pipe 27 drives the rotation of the corrugated pipe 26 and the material pipe elbow 213, thereby adjusting the orientation of the material pipe elbow 213 to ensure the accuracy of feeding.

[0069] In addition, since the lifting plate 25 is rotatably connected to the corrugated tube 26 through the rotating ring 211, the lifting and rotating actions of the entire tube assembly 2 do not interfere with each other; thereby improving the mobility and flexibility of the tube assembly 2 in unloading.

[0070] When the material level is low, the material level sensor 7 cannot detect the material level. The material level sensor 7 transmits a photoelectric signal to the material shortage warning light 9, which then lights up to remind the staff to add material to the feeding box 1.

[0071] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
