Description

Technical Field

[0001] The present invention relates to a rotating device, specifically a chain drive rolling device. Background Art

[0002] When installing and debugging certain large rotary (rolling) equipment such as cylindrical equipment, due to the large diameter of the cylindrical equipment, there are inconvenient areas for installation and debugging in the circumferential direction of the cylindrical equipment, and it is impossible to carry out installation and debugging work efficiently. Therefore, a rolling device is needed, such as:

[0003] The invention with application number 201710174633.8, a rolling device applied to cylindrical equipment;

[0004] The utility model with application number 201520614826.7, a rear rolling device;

[0005] The invention with application number 201110094180.0, a rolling device for anti-corrosion spraying of wind turbine towers;

[0006] The invention with application number 201911384306.0, an automatic rolling device for large-diameter long-section hollow cylinders;

[0007] The invention with application number 201810635769.9, a rolling device for large rotary products;

[0008] The invention with application number 201810910102.5, a rolling device for repairing swing-type arc-shaped grinding rolls;

[0010] The invention with application number 201810725893.4, a rolling device for space rocket bodies;

[0011] It can be seen that the application of rolling devices is very extensive.

[0012] At present, the two ends of common traditional rolling devices are roller-rolling belt support devices, and the middle is a gear-ring drive device (it is necessary to install a relatively large rigid support ring and ring gear on the rolling body, supported by rollers at the bottom, and then the ring gear is driven by the gear to rotate circumferentially). The equipment structure is complex. For the gear-ring drive method, it is difficult to adjust the meshing clearance and parallelism, and the equipment is large in volume and high in cost; for the roller-rolling belt line contact support method, the contact stress is large, the wear is fast, and the replacement is troublesome (requiring a lifting device). For equipment that does not allow any auxiliary parts to be installed on the rolling body and has contact stress requirements on the outer surface of the rolled body, this solution cannot meet the use requirements. Summary of the Invention

[0013] The object of the present invention is to provide a chain drive rolling device. The present invention uses chain plates for driving and supporting, avoiding damage to the surface of the rolling body, and having low equipment cost and small volume.

[0014] To achieve the above object, the technical solution adopted by the present invention is:

[0016] Furthermore, the chain drive rolling devices are used in pairs, and a driving mechanism for driving the driving shaft 4 to rotate is installed on one of the chain drive rolling devices.

[0017] Furthermore, a driving mechanism for driving the driving shaft 4 to rotate is also arranged on the housing 1.

[0018] Furthermore, the driving mechanism includes a speed reducer 6 and a servo motor 7 installed outside the housing 1, the servo motor 7 is connected to the speed reducer 6 in a matching manner, and the speed reducer 6 is in transmission connection with the driving shaft 4.

[0019] Furthermore, the chain plate conveying chain 3 includes two chains 10, and is composed of arranging a plurality of cast rubber chain plates 9 between the two chains 10.

[0020] Furthermore, a plurality of guide rollers 11 are evenly arranged on the outer side of the chain 10.

[0021] Furthermore, a pair of sprockets 12 are arranged on each of the driving shaft 4, the driven shaft 5 and the tensioning shaft 8, and the sprockets 12 are in matching connection with the chains 10.

[0022] Furthermore, there are two tensioning shafts 8, which are installed at the lower part of the housing 1 and together with the driving shaft 4 and the driven shaft 5 form an inverted isosceles trapezoid.

[0023] Furthermore, a lifting device 2 is also arranged inside the housing 1, and the lifting device 2 is used to lift and jack up the chain plate conveying chain 3 located above.

[0024] Further, the lifting device 2 includes an arc-shaped bracket 13 that matches the arc-shaped part of the chain plate conveyor chain 3. Two sets of sliding mechanisms are symmetrically arranged on the left and right at the bottom of the arc-shaped bracket 13. The sliding mechanism includes a slider 14 and a slide rail 15 that cooperate with each other. The slide rail 15 is fixedly installed on the housing 1. The slider 14 is connected to the arc-shaped bracket 13 through a connecting plate 18. The two ends of the connecting plate 18 are respectively hinged to the slider 14 and the arc-shaped bracket 13. A screw mechanism 16 is provided on the slider 14, and the screw mechanism 16 is also equipped with a screw driving mechanism 17. The screw driving mechanism 17 is fixedly installed on the housing 1.

[0025] The beneficial effects of the present invention compared with the traditional rolling device are as follows:

[0026] 1. The rolling device of the present invention is small in size, simple in operation, requires little power, and does not need to add rigid supports to the rolling body.

[0027] 2. The driving method of the rolling device of the present invention is different from that of the traditional rolling device: the traditional rolling device adopts a gear-ring driving method, and the equipment is large in size and high in cost; the present invention adopts a chain driving method, the equipment is small in size, the driving mechanism is simple in structure, and the cost is low. In addition, the running noise is also very small.

[0028] 3. The supporting method of the rolling device of the present invention is different from that of the traditional rolling device: the traditional rolling device adopts a roller-rolling belt line contact support method, and the contact stress between the roller and the rolling belt is large, the wear is fast, and the replacement is troublesome (requiring lifting equipment); the present invention uses a cast rubber chain plate to support the rolling body, and the cast rubber flexible surface between the rolling body and the cast rubber chain plate is a surface contact method, which greatly reduces the contact stress on the surface of the rolling body, avoids damage to the surface of the rolling body by the drive system, the friction coefficient between the cast rubber chain plate and the rolling body is large, there is no relative sliding and no wear, and the cast rubber chain plate is small in size and light in weight and can be easily replaced.

[0029] 4. The installation method of the rolling device of the present invention is different from that of the traditional rolling device: the traditional rolling device has a roller-rolling belt support device at both ends and a gear-ring drive device in the middle, and the equipment structure is complex; it is difficult to adjust the meshing clearance and parallelism of the gear-ring. The present invention adopts a profiled chain track, and the arc-shaped chain plate conveyor chain of the equipment forces the chain to form a concentric circle with the same diameter as the rolling body, ensuring the accurate positioning of the rolling body; the compressibility of the rubber on the cast rubber chain plate ensures the uniform distribution of the load of the rolling body on the chain plate, preventing local extrusion deformation of the rolling body.

[0030] 5. The equipment functions of the rolling device of the present invention are different from those of the traditional rolling device: the traditional rolling device is powerless for the auxiliary device with protrusions installed in the longitudinal direction of the rolling body. The present invention can avoid the protrusions in the longitudinal direction by adopting a partial intermittent chain plate, expanding the compatibility of the rolling body and increasing the application range of the present invention.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] In order to better understand the present invention, the technical solutions of the present invention will be further described below in conjunction with embodiments.

[0036] A chain drive rolling device, which is used in pairs and respectively supports both ends of the rolling body.

[0037] The chain drive rolling device includes a U-shaped housing 1. Driving shafts 4 and driven shafts 5 are respectively arranged at both ends of the U-shaped housing 1, and a chain plate conveyor chain 3 is arranged on the driving shafts 4 and the driven shafts 5. The upper part of the chain plate conveyor chain 3 is suspended in an arc shape between the driving shaft 4 and the driven shaft 5; the lower part of the chain plate conveyor chain 3 is tensioned by tensioning shafts 8. There are two tensioning shafts 8, which are installed at the lower part of the housing 1 and together with the driving shaft 4 and the driven shaft 5 form an inverted isosceles trapezoid.

[0038] A driving mechanism for driving the driving shaft 4 to rotate is installed on one of the chain drive rolling devices to drive the rolling body to rotate; there is no driving mechanism on the other chain drive rolling device, and it rotates passively following the rolling body. The driving mechanism includes a speed reducer 6 and a servo motor 7 installed outside the housing 1. The servo motor 7 and the speed reducer 6 are connected in a matching manner, and the speed reducer 6 is in transmission connection with the driving shaft 4.

[0039] The chain plate conveyor chain 3 includes two chains 10, which are composed of arranging a plurality of cast rubber chain plates 9 (cast rubber) between the two chains 10; a plurality of guide rollers 11 are evenly arranged on the outer sides of the chains 10. A pair of sprockets 12 are arranged on each of the driving shaft 4, the driven shaft 5 and the tensioning shaft 8, and the sprockets 12 are in matching connection with the chains 10.

[0040] Such as Figure 3As shown in the figure, a lifting device 2 is further provided inside the housing 1, which is located inside the chain plate conveying chain 3. The lifting device 2 is used to lift and jack up the chain plate conveying chain 3 located above. The lifting device 2 includes an arc-shaped bracket 13 that matches the arc-shaped part of the chain plate conveying chain 3 and is used to support the chain plate conveying chain 3. Two sets of sliding mechanisms are symmetrically arranged on the left and right at the bottom of the arc-shaped bracket 13. The sliding mechanism includes a slider 14 and a slide rail 15 that cooperate with each other. The slide rail 15 is fixedly installed on the housing 1. The slider 14 is connected to the arc-shaped bracket 13 through a connecting plate 18. The two ends of the connecting plate 18 are respectively hinged to the slider 14 and the arc-shaped bracket 13. A screw mechanism 16 is provided on the slider 14, and the screw mechanism 16 is also equipped with a screw driving mechanism 17. The screw driving mechanism 17 is fixedly installed on the housing 1. The screw driving mechanism 17 includes a reducer and a motor. Working process: The screw driving mechanism 17 drives the screw in the screw mechanism 16 to rotate. The rotation of the screw drives the slider 14 to slide along the slide rail 15. The movement of the slider 14 drives the connecting plate 18 to rotate. The rotation of the connecting plate 18 completes the actions of lifting and lowering the arc-shaped bracket 13.

[0041] Usage process and principle of the chain drive rolling device:

[0042] The chain drive rolling devices are used in pairs and are respectively located at both ends of the rolling body. One chain drive rolling device at one end has power, and the chain drive rolling device at the other end has no power and rotates passively. The rolling body is placed on the chain plates of the arc section to be supported. Relying on the rubber on the surface of the cast rubber chain plate 9 and the arc-shaped flexible structure, the rolling body is in surface contact with multiple cast rubber chain plates 9. Driven by the servo motor 7 on the main shaft 4, the chain 10 rotates cyclically along the profiling track (arc). When rotating, the rolling body is driven to rotate by the friction force between the rolling body and the cast rubber chain plate 9. When the rolling body needs to be stationary, the lifting device 2 can lift and support the rolling body to bear the load.

[0043] The above description is only for the application embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited by this. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
