Description

Technical Field

[0001] The utility model belongs to the technical field of extended horizontal shaft spiral conveyors, and relates to an oil-injectable hanger and bushing combination device. Background Technique

[0002] A spiral conveyor is a mechanical device that uses an electric motor to drive a spiral to rotate, and the material relies on its own gravity and the friction force with the trough wall to achieve fixed-point conveying under the thrust of the spiral blade; an extended horizontal spiral conveyor refers to a spiral conveyor whose conveying direction is parallel to the ground and has a relatively long conveying stroke; an extended horizontal spiral conveyor refers to a horizontal spiral conveyor with multiple sections of spirals exceeding 30 meters; an extended horizontal spiral conveyor mainly consists of a reduction motor, a spiral shaft, spiral blades, a U-shaped long trough, a long trough cover plate, a head bearing, a tail bearing, a spiral hanging shaft device, a motor coupling, a feed hopper, and a discharge port; it is a filter cake conveying device supporting a filter press.

[0003] The spiral hanging shaft device (reference can be made to the patent content with the patent number ZL202121707919.6) mainly consists of a T-shaped hanging shaft frame, a hanger ear, a combined bushing, and a coupling rotating body, and is used to connect the spiral shafts on both sides. By balancing the spiral shafts on both sides, it can prevent the spiral shafts from being deformed by gravity due to being too long; the T-shaped hanging shaft frame consists of a hanging shaft cross beam and a hanging shaft cross rib, and the hanging shaft cross rib is welded by stainless steel plates and looks like a cross when viewed from above.

[0004] Existing spiral hanging shaft devices all have the following defects: 1. There is no dedicated oil injection device to add oil to the combined bushing, which will cause the copper bushings in the coupling rotating body and the combined bushing to be easily damaged by friction, and at the same time, not lubricating it with oil for a long time may also emit harsh noises; 2. If you want to lubricate the spiral hanging shaft device with oil, you can only disassemble the combined bushing, take out the coupling rotating body and the copper bushing for oil injection lubrication treatment, and at the same time, you also need to disassemble and lift the spiral shafts on both sides. The entire oil injection lubrication process is cumbersome, inefficient, time-consuming and laborious, and the spiral conveyor also needs to be shut down, delaying production; 3. The nylon bushing in the combined bushing is prone to falling off after a long time, and reinstalling or replacing the nylon bushing still requires disassembling the spiral hanging shaft device, with a cumbersome and inefficient process and production delay. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the existing spiral hanging shaft device, solve the technical problems of the existing technology without an oil injection device for the combined bushing, cumbersome and laborious manual disassembly for oil injection, low oil injection efficiency, and easy falling off of the nylon bushing, and provide an oil-injectable hanger and bushing combination device.

[0006] The technical solution adopted by this utility model to solve the existing technical problems is: an oil-fillable hanger and bushing combination device, mainly composed of five parts: hanger beam, square tube hanger, oil filling assembly, assembled bushing, and anti-detachment chuck. The innovative overall structure has outstanding substantive features compared with the existing technology: (1) An oil filling assembly for oiling the spiral hanger device is added, which consists of an oil filling hopper and an oil filling guide. The upper end of the oil filling guide is welded to the oil hole of the hanger beam in the middle position, and the lower end is welded to the oil hole of the bushing at the center of the upper end face of the assembled bushing. After adding lubricating oil to the oil filling hopper, the lubricating oil will enter the interior of the assembled bushing along the oil filling guide to achieve the purpose of oiling and lubrication; (2) The hanger beam in the middle position of the original T-type hanger and the center of the upper end face of the original outer bushing are... The opening is slightly larger than the outer diameter of the oil injection conduit of the oil injection assembly. The openings are the crossbeam oil hole and the bushing oil hole. The purpose is to allow the oil injection conduit of the oil injection assembly to pass through them. The purpose of fixing the oil injection assembly and sealing the oil injection is achieved by welding the contact points between the crossbeam oil hole and the bushing oil hole and the oil injection conduit. (3) The cross rib structure of the original T-type hanger is changed to a square tube hanger. The purpose is to provide installation space for the oil injection assembly so that the bottom of the oil injection conduit of the oil injection assembly can be aligned with the middle position of the upper end face of the assembled bushing, ensuring that the lubricating oil can evenly seep into both sides of the assembled bushing. (4) Anti-detachment chucks are added to both sides of the original combined bushing. The anti-detachment chucks can lock the nylon bushing inside the assembled bushing to prevent it from coming off after long-term use.

[0007] Furthermore, the aforementioned hanger beam is made of stainless steel plate by bending, with mounting holes at both ends for mounting the hanger beam on the trough wall of the screw conveyor. An oil hole is also provided in the middle of the beam, with an outer diameter slightly larger than the outer diameter of the oil injection pipe, allowing the oil injection pipe to pass downwards. At the same time, welding the oil hole to the oil injection pipe can firmly fix the oil injection assembly to the hanger beam.

[0008] Furthermore, the square tube suspension rod is made of stainless steel square tube, with its upper end flush and welded to the center of the hanger beam, and its lower end arc-shaped and welded to the assembled bushing; its function is to provide installation space for the oil injection assembly, so that the bottom of the oil injection conduit of the oil injection assembly can pass through the inside of the square tube suspension rod and be aligned with the bushing oil hole on the assembled bushing.

[0009] Furthermore, the oil injection assembly consists of an oil injection hopper and an oil injection conduit. The oil injection hopper is funnel-shaped to facilitate the addition of lubricating oil into the oil injection assembly. The oil injection conduit is a stainless steel round tube that can pass through the oil hole of the hanger beam, the inside of the square tube hanger, and the oil hole of the assembled bushing to directionally deliver lubricating oil to the inside of the assembled bushing. The length of the oil injection conduit is about 3cm longer than the length of the square tube hanger so that the square tube hanger can be lifted during assembly, leaving a gap between the square tube hanger and the assembled bushing, which facilitates welding the oil injection conduit to the oil hole of the bushing.

[0010] Furthermore, the assembled bushing consists of an upper bushing semicircle, a lower bushing semicircle, and an outer fastening lug. The outer fastening lug is welded to the outer edge of the upper and lower bushing semicircles. There are four bolt holes on both sides of the outer fastening lug. By tightening the bolts, the upper and lower bushing semicircles can be tightly fitted together, forming a circular shape in the middle. In addition, a bushing oil hole is provided in the middle of the upper end face of the upper bushing semicircle. The outer diameter is slightly larger than the outer diameter of the oil injection conduit. The lower end of the oil injection conduit is welded to the bushing oil hole. Lubricating oil can pass through the bushing oil hole and enter the interior of the assembled bushing to lubricate the nylon bushing and the rotating body of the coupling. Chuck holes with internal threads are also provided on both sides of the assembled bushing for installing anti-loosening chucks.

[0011] Furthermore, the anti-detachment chuck is ring-shaped and has four bolt holes. The positions of the bolt holes match the positions of the chuck holes of the assembled bushing. The inner diameter is slightly smaller than the inner diameter of the assembled bushing and slightly larger than the inner diameter of the inner circle formed by the nylon bushing. It is fixed on both sides of the assembled bushing with bolts. Its function is to hold the nylon bushing tightly and prevent it from coming off.

[0012] The connection relationship of the main components is as follows: (1) The upper end of the square tube hanger is vertically welded to the center of the lower end face of the hanger beam; (2) The oil injection conduit of the oil injection assembly passes through the oil hole of the hanger beam and the square tube hanger in sequence. The lower end of the oil injection conduit is welded to the oil hole of the assembled bushing, and the upper end is welded to the oil hole of the hanger beam; (3) The assembled bushing is welded to the end of the square tube hanger with the arc surface.

[0013] The beneficial effects of the oil-injectable hanger and bushing combination device provided by this utility model are: (1) An oil injection device-oil injection assembly is added, and the end of the oil injection device can directly reach the oil injection point-the interior of the assembled bushing to lubricate the nylon bushing and the rotating body of the coupling. This not only makes oil injection and lubrication more convenient, but also saves time and effort, making it more convenient for maintenance personnel, improving the working efficiency of the screw conveyor, and avoiding the generation of operating noise; (2) By adding anti-detachment chucks on both sides of the assembled bushing, the nylon bushing is prevented from coming off; (3) Combining the above two points, the disassembly of the screw hanger device is avoided, ensuring the continuous and stable production of the screw conveyor, and also improving the production efficiency of customers, thus solving problems and increasing efficiency.

[0024] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the oil-fillable hanger and bushing combination device. The described embodiments are only a part of the preferred embodiments of the present invention, and not all of the embodiments. All other embodiments without inventiveness that are made by those skilled in the art based on the embodiments of the present invention are within the protection scope of the present invention. Example

[0025] A lubricating hanger and bushing assembly 13 mainly consists of five parts: a hanger beam 1, a square tube lifting rod 2, an oiling assembly 3, an assembled bushing 4, and an anti-detachment chuck 5. Its features include: (1) the oiling assembly 3 is composed of an oiling hopper 7 and an oiling conduit 8. The oiling conduit 8 passes sequentially from top to bottom through the oil hole 6 in the middle of the hanger beam 1, the square tube lifting rod 2, and the bushing oil hole 11 at the center of the upper end face of the assembled bushing 4. After lubricating oil is added to the oiling hopper 7 of the oiling assembly 3, the lubricating oil is subjected to gravity. The oil flows from top to bottom into the assembled bushing 4 along the oil injection pipe 8, which can provide directional and precise lubrication for the nylon bushing 14 and the rotating body 15 of the coupling; (2) The assembled bushing 4 has added screw holes with internal threads and anti-detachment chucks 5 on both sides. The inner diameter of the anti-detachment chuck 5 is smaller than the inner diameter of the inner circle of the assembled bushing 4 and slightly larger than the inner diameter of the inner circle formed by the nylon bushing 14. It is fixed on both sides of the assembled bushing 4. The anti-detachment chuck 5 is tightened on the assembled bushing 4 by bolts, which can hold the nylon bushing 14 tightly and prevent the nylon bushing 14 from coming off.

[0026] The aforementioned hanger beam 1 is made of stainless steel plate by bending. It has mounting holes at both ends for mounting the hanger beam 1 on the trough wall of the screw conveyor. It also has an oil hole 6 in the middle, with an outer diameter slightly larger than the outer diameter of the oil injection pipe 8, so that the oil injection pipe 8 can pass downward. At the same time, it is welded to the oil injection pipe 8 at the oil hole 6, so that the oil injection assembly 3 can be firmly fixed on the hanger beam 1.

[0027] The square tube suspension rod 2 is made of stainless steel square tube. Its upper end is flush and welded to the center of the hanger beam 1, and its lower end is arc-shaped and welded to the assembled bushing 4. Its function is to provide installation space for the oil injection assembly 3, so that the bottom of the oil injection conduit 8 of the oil injection assembly 3 can pass through the inside of the square tube suspension rod 2 and be aligned with the bushing oil hole 11 on the assembled bushing 4.

[0028] The oil filling assembly 3 consists of an oil filling hopper 7 and an oil filling conduit 8. The oil filling hopper 7 is funnel-shaped, which facilitates the addition of lubricating oil into the oil filling assembly 3. The oil filling conduit 8 is a stainless steel round tube that can pass through the crossbeam oil hole 6 of the hanger beam 1, the inside of the square tube hanger 1, and the bushing oil hole 11 of the assembled bushing 4 to deliver lubricating oil in a directional manner to the inside of the assembled bushing 4. The length of the oil filling conduit 8 is about 3cm longer than the length of the square tube hanger 2, so that the square tube hanger 2 can be lifted during assembly to leave a gap between the square tube hanger 2 and the assembled bushing 4, which facilitates the welding of the oil filling conduit 8 to the bushing oil hole 11.

[0029] The assembled bushing 4 consists of an upper bushing semicircle 9, a lower bushing semicircle 10, and an outer sleeve fastening ear 12. The upper and lower outer sleeve fastening ears 12 are welded to the outer edges of the two bushing semicircles. There are four bolt holes on both sides of the outer sleeve fastening ears 12. By tightening the bolts, the upper bushing semicircle 9 and the lower bushing semicircle 10 can be tightly fitted together, forming a circular shape in the middle. In addition, a bushing oil hole 11 is provided in the middle of the upper end face of the upper bushing semicircle 9. The outer diameter is slightly larger than the outer diameter of the oil injection conduit 8. The lower end of the oil injection conduit 8 is welded to the bushing oil hole 11. Lubricating oil can pass through the bushing oil hole 11 and enter the interior of the assembled bushing 4 to lubricate the nylon bushing 14 and the coupling rotating body 15. On both sides of the assembled bushing 4, there are also chuck holes with internal threads for installing anti-loosening chucks 5.

[0030] The anti-detachment chuck 5 is ring-shaped and has four bolt holes. The positions of the bolt holes match the positions of the chuck holes of the assembled bushing 4. The inner diameter of the anti-detachment chuck 5 is slightly smaller than the inner diameter of the inner circle of the assembled bushing 4 and slightly larger than the inner diameter of the inner circle formed by the nylon bushing 14. It is fixed to both sides of the assembled bushing 4 with bolts. Its function is to hold the nylon bushing 14 tightly and prevent the nylon bushing 14 from coming off.

[0031] The oil-lubricated hanger and bushing combination device 13 provided by this utility model not only solves the problem of tedious, time-consuming and laborious oiling of nylon bushing 14 and coupling rotating body 15, but also solves the problem of tedious and inefficient replacement or adjustment of nylon bushing 14. It ensures that the screw conveyor can be lubricated without stopping, improves production efficiency, and avoids noise caused by lack of lubrication during operation. Example

[0032] An extended horizontal screw conveyor mainly includes a drive motor, a screw shaft 17, screw blades, a screw suspension device 16, a casing, an inlet, and an outlet. The screw shaft 17 can be divided into 2-3 sections, and adjacent screw shafts 17 are connected by the screw suspension device 16, which serves to balance and suspend the material and ensure synchronous rotation. Driven by the drive motor, the screw shaft 17 and the screw blades rotate together, and the screw blades push the material from one end of the inlet to one end of the outlet. The spiral shaft device 16 is equipped with the oil-fillable hanger and bushing combination device 13 described in Embodiment 1. Lubricating oil can be added to the oil filling hopper 7 of the oil-fillable hanger and bushing combination device 13 to directly lubricate the nylon bushing 14 and the coupling rotating body 15 of the spiral shaft device 16. This avoids the need to lubricate the spiral shaft device 16 with oil, replace or adjust the nylon bushing 14, and disassemble the spiral shaft device 16 and the spiral shaft 17. This saves time and effort and ensures the continuous and stable operation of the extended horizontal screw conveyor.
