Description

Technical Field

[0001] The invention belongs to a cable pulling device, in particular to an intelligent cable pulling device. Background Art

[0002] Whether it is a traditional cable or an optical cable, the surface is smooth and it is wound around the rotating core layer by layer to form a cable drum. The existing cable releaser is just a rotating table. When in use, the rotating core is placed on the rotating table and the workers pull the cable out. Whether it is an underground pipeline or the ground, the pulling process is hindered by friction. Therefore, long-distance wiring is pulled by multiple people in relays, which uses a lot of manpower and has high labor intensity. It is difficult for workers to pull the wire at a uniform speed. Sometimes they must stop when encountering obstacles in front. The workers in the middle actively adjust the speed to adapt to the speed of the workers in front. Since the rotating table has no braking measures and relies on manual waiting for braking, once the worker at the last end stops, the waiting worker fails to pull the rotating table for braking in time, and the inertia force causes the cable to still be released outward and scattered on the ground. The cable with a smooth surface is easy to be entangled, and the density of the cable winding in the cable drum is destroyed, and it is also easy to slip down or loosen. When the workers in front continue to work, the cable is easy to get tangled or even scrapped, resulting in a waste of manpower and material resources. Summary of the invention

[0003] The purpose of the present invention is to overcome the disadvantage of the existing cable pay-off device that relies on manual dragging, and to provide an intelligent cable puller which uses less manpower and can reduce the labor intensity of workers.

[0004] The technical solution adopted by the present invention is an intelligent cable puller, the main points of which are: it consists of a cable pulling device and a cable unwinding device, the cable pulling device consists of a power machine, a clutch, a controller, a transmission, and a cable puller, the power machine, the clutch, the transmission, and the cable puller are connected in sequence, the controller and the clutch are electrically connected in sequence, the controller is located at the front end of the cable puller, the controller controls the clutch with the movement speed of the cable, thereby controlling the rotation speed of the transmission and the cable puller, and the cable unwinding device is located at the rear end of the cable pulling device.

[0005] The present invention creatively designs a powered intelligent cable pulling method that controls the power pulling speed at the rear according to the moving speed of the cable in front, thereby reducing manpower and lowering the labor intensity of workers, and laying a foundation for realizing fully automatic intelligent cable pulling in open areas. Since the current cable layout is often in densely populated areas, it is inconvenient to use power equipment to open a way in front, so manual work is still required to open a way. The present invention only needs one worker to pull the cable at the front, and the existence of power and cables in the rear will objectively prevent people from accidentally breaking in.

[0006] The controller is composed of a shell, a power supply, a speed sensor, a control module, a speed sensing wheel and a wire pressing guide wheel matched therewith. The speed sensor is installed on the speed sensing wheel and is electrically connected to the control module. The wire pressing guide wheel is opposite to the speed sensing wheel. The cable passes through the shell and passes through the junction of the speed sensing wheel and the wire pressing guide wheel. A cable protection ring is installed in the cable hole of the shell.

[0007] Each power unit is equipped with a controller, and the distance between the controller and the host is small, which reduces the complexity of the control system.

[0008] The wire pressing guide wheel, the speed sensor wheel and the control module are located in the middle of the controller housing, the speed sensor is electrically connected to the control module, and the two batteries are located on both sides. The weight of the entire controller is evenly distributed.

[0009] The cable puller is composed of a fixed plate and a plurality of cable pull wheels. The cable pull wheels are arranged in two rows opposite to each other. The cable pull wheels are connected to the output shaft of the transmission. The cable passes through the middle of the two rows of cable pull wheels. The cable puller composed of multiple cable pull power wheels has a large overall pulling force. The pulling force of a single cable pull power wheel is small, and the damage to the cable is small. Generally, a cable puller is arranged every 100-800 meters.

[0010] A crawler track is arranged around the outer circumference of each row of cable pulleys, and the output shaft of the transmission is connected to a cable pulley in each row through a chain. The chain and the cable pulleys are connected in such a way that the outer side of the chain meshes with a cable pulley in one row, and the inner surface of the chain meshes with a cable pulley in the other row, so that the linear speed directions of the opposite surfaces of the two cable pulleys are consistent.

[0011] The present invention creatively uses a special chain winding method to make the two rows of cable pulling wheels rotate in opposite directions, one row is clockwise and the other row is counterclockwise, so that the linear speeds on the opposite sides of the crawler are consistent in magnitude and direction, and the cables embedded therein are pulled or pushed forward, thereby achieving the purpose of power cable pulling.

[0012] The cable unwinding device is composed of a floor bracket, a load-bearing turntable, a brake gear ring, an electromagnetic brake, a sensor encoder, a sensor encoder bracket, a power supply, and a control system. There is a central axis tube in the center of the floor bracket. The load-bearing turntable and the brake gear ring are fixed to the outside of the central axis tube through bearings. The brake gear ring is below the load-bearing turntable. The two are linked. The electromagnetic brake is connected to the brake gear ring. The sensor encoder is fixed on the sensor encoder bracket. A transmission device is connected above the sensor encoder. The control system is electrically connected to the power supply, the sensor encoder, and the electromagnetic brake respectively.

[0013] This is a vertical cable pay-off device that matches the cable pulling device. When in use, the cable is passed through the sensor encoder and connected to the transmission device before being pulled out. The transmission device converts the linear motion of the cable into a rotation signal and transmits it to the sensor encoder. When the sensor encoder senses that the speed of the cable in front decreases or stops moving, it transmits the signal to the control system. The control system controls the electromagnetic brake to generate different magnetic forces to attract the brake gear ring, so that the rotation speed of the brake gear ring decreases or stops, thereby reducing or stopping the rotation speed of the load-bearing turntable and cable drum that move together. When the cable is pulled normally, the electromagnetic brake rotates with the brake gear ring without resistance.

[0014] The cable unwinding device is composed of a floor bracket, a load-bearing turntable, a brake, and a controller. A brake gear ring is fixed under the load-bearing turntable, and the brake cooperates with the brake gear ring. There is a central axis tube in the center of the floor bracket, and the load-bearing turntable is fixed to the outside of the central axis tube through a bearing. The brake gear is connected to the brake motor and is located below the brake gear ring. The brake gear ring is meshed with the brake gear. The controller is located in front of the floor bracket, and the controller controls the brake motor according to the movement speed of the cable.

[0015] This is another style of vertical cable pay-off device, which adds a brake to the cable pay-off device to achieve the function of automatic speed reduction, which can effectively prevent the cable from getting entangled and reduce labor. A controller similar to that of the cable puller is used to control the operation of the brake motor, making the overall equipment structure simple.

[0016] The cable unwinding device is composed of load-bearing brackets on both sides, a central axis, a turntable with a brake gear ring fixed on the back, a brake, and a controller. The controller is electrically connected to the brake. The first load-bearing bracket is composed of two supporting feet fixed on the outside of the first central axis tube seat, and the second load-bearing bracket is composed of two supporting feet fixed on the outside of the second central axis tube seat. The vertical height of the two supporting feet after standing is not less than the center height of the cable drum in the horizontal state. Two bearings and retaining rings are installed inside the second central axis tube seat. The retaining ring is located between the two bearings to position the bearings in the axial direction. A turntable shaft fixed to the turntable is sleeved in the bearing. One end of the central axis is fixedly connected to the turntable shaft and rotates simultaneously with the turntable shaft. The other end of the central axis is connected to the first central axis tube seat through a bearing. The brake is fixed on the supporting feet of the second central axis tube seat and cooperates with the brake gear ring of the turntable.

[0017] This is another embodiment of the present invention. The horizontal cable unwinding device is matched with the cable pulling device. When in use, the cable is passed through the central axis and fixed on the load-bearing brackets on both sides. The axis of the central axis is parallel to the ground, and the cable drum is changed from vertical to horizontal. When installing, first turn a support foot and a turntable on one side of the second central axis tube seat to the ground, close to the cable drum on one side of the cable drum, insert the central axis from the other end into the center hole of the cable drum, and fix it with the second central axis tube seat, and then fix the first central axis tube seat with the central axis. At this time, the load-bearing bracket where the first central axis tube seat is located is also a support foot on the ground, and the other support foot is tilted. After the fixation is completed, use a crowbar to rotate the load-bearing bracket so that the double support feet are on the ground, and the overall center of gravity displacement is small, which saves effort. A brake gear ring and a brake are also added on one side of the second central axis tube seat. The brake is connected to the controller. The controller controls the rotation speed of the cable drum according to the forward speed of the cable. When the controller senses that the speed of the front cable decreases or stops moving, the controller controls the brake to reduce or stop the rotation speed of the brake gear ring. When the cable is pulled normally, the brake gear ring rotates with the cable drum.

[0018] The outer side of the floor bracket is fixed with an anti-loosening device, which is composed of a fixed rod, an elastic pressure rod, a reinforcing rod, and a pipe sleeve. The elastic pressure rod is connected to the fixed rod, the reinforcing rod is connected to the pipe sleeve, the other end of the reinforcing rod is connected to the top of the fixed rod, and the pipe sleeve is connected to the central axis pipe sleeve. This is a vertical anti-loosening (anti-slipping) device that cooperates with the vertical cable pay-off device. In addition to the existing cable pay-off device having no braking system, the cable drum continues to pay out the cable due to inertia after the front worker stops pulling the cable, causing the cable to be entangled and knotted, and the cable in the cable drum is loose and slips down, which is easy to get knotted. Using the elastic pressure rod to press the outermost cable of the cable drum can effectively prevent the cable from slipping down.

[0019] There is an anti-loosening device, which is composed of a fixing rod, an elastic pressure rod, and a reinforcing rod. The elastic pressure rod is connected to the fixing rod, and two reinforcing rods are respectively connected to the two ends of the fixing rod. The first center axis tube seat and the second center axis tube seat are respectively provided with fixing holes matched with the reinforcing rods. The two reinforcing rods are respectively fixed to the first center axis tube seat and the second center axis tube seat. This is an anti-loosening device matched with the horizontal cable pay-off device.

[0020] The present invention creatively designs a power cable pulling device that controls the power pulling speed at the rear according to the forward movement speed of the cable, thereby reducing manpower and the labor intensity of workers, and laying a foundation for realizing fully automatic cable pulling in open areas. In the cable pulling device, the present invention creatively uses a special chain winding method to make the two rows of cable pulling wheels turn in opposite directions, one row is clockwise and the other row is counterclockwise, so that the linear speed and direction of the opposite sides of the crawler are consistent, and the cable embedded therein is pulled or pushed forward to achieve the purpose of power pulling. The total pulling force is increased in the form of a combined force, and the extrusion force on the cable surface is reduced, reducing the damage to the cable surface caused by the extrusion force. The cable unwinding device with a brake can stop the cable drum from discharging the cable in time when the front stops pulling the cable, preventing the cable from being entangled and knotted. At the same time, the elastic pressure rod can prevent the cable from loosening, ensuring that the cable is always wound in an orderly manner. The design of the horizontal cable unwinding device saves effort in cable placement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention is described in detail below in conjunction with the drawings so that those skilled in the art can better understand the present invention.

[0034] Embodiment 1, as Figure 1 , 2 As shown, an intelligent cable puller consists of a cable pulling device and a cable unwinding device. The cable pulling device consists of a power machine 100, a clutch 101, a controller 300, a transmission 103, and a cable puller 400. The power machine 100, the clutch 101, the transmission 103, and the cable puller 400 are installed in the same box 104, and a push wheel 105 is installed at the bottom of the box. The power machine, the clutch, the transmission, and the cable puller are connected in sequence, and the controller and the clutch are electrically connected in sequence. The controller is located at the front end of the cable puller and is installed in another box. Each power is provided with a controller, and the distance between the controller and the host is small, which reduces the complexity of the control system. The controller controls the clutch according to the movement speed of the cable, thereby controlling the rotation speed of the transmission and the cable puller, and the cable unwinding device is located at the rear end of the cable pulling device.

[0035] like Figure 3 , 4As shown, the controller 300 is composed of a housing 301, a speed sensor 309, a power supply 302, a control module 303, a speed sensing wheel 304 and a wire crimping guide wheel 305 matched therewith. The power supply uses a battery. The wire crimping guide wheel, the speed sensing wheel and the control module are located in the middle of the controller housing, and two batteries are located on both sides. The shell is divided into an upper cover and a lower box, which are buckled into one. The speed sensor is installed on the speed sensing wheel 304. The wire pressing guide wheel is opposite to the speed sensing wheel and is located above the speed sensing wheel. The wire pressing guide wheel shaft 3051 is fixed in the upper cover, and a downward spring 3052 is provided to contact the wire pressing guide wheel with the cable. The front end of the speed sensing wheel shaft can also be fixed to the shell through a bearing. There is a support rod 307 fixed to the bottom of the shell in the middle, and a bearing seat 308 is fixed on the support rod. The tail end of the speed sensing wheel shaft passes through the bearing in the bearing seat, and the tail end is outside the bearing. The end face is connected to the speed sensor 309. The other part of the speed sensor is fixed to the side wall of the shell together with the control module 303. Relative cable holes are formed on both sides of the shell, and a cable protection ring 306 is installed in the cable hole of the shell to protect the cable from being scratched by the shell. The center line of the cable hole is perpendicular to the center line of the speed sensing wheel. The cable passes through the cable hole of the shell and passes through the opposite part of the speed sensing wheel and the wire pressing guide wheel. The wire pressing guide wheel presses the cable downward to make it contact with the speed sensing wheel, driving the speed sensing wheel to rotate. The speed sensor at the end of the speed sensing wheel shaft detects the rotation speed of the speed sensing wheel shaft, thereby sending control information to the rear end brake or transmission 103 through the control module. In the figure, the wire pressing guide wheel and the speed sensing wheel are made of rubber and have a certain elasticity. They can also be made of metal, and the contact surface with the cable is made into an arc shape that matches the outer diameter of the cable.

[0036] like Figure 1 , 5 As shown, the cable puller 400 is composed of a fixed plate and a plurality of cable pulling wheels 402, eight of which are shown in the figure. The cable pulling wheels are arranged opposite to each other in two rows, with four wheels in each row, fixed on the fixed plate. The cable pulling wheels are connected to the output shaft of the transmission, and the cable 10 passes through the middle of the two rows of cable pulling wheels.

[0037] Each row of cable pulleys is surrounded by a crawler 403, and the output shaft 1031 of the transmission is connected to the shaft 4021 of a cable pulley in each row of cable pulleys through a chain 404. The chain is connected to the cable pulley in such a way that the outer side of the chain is meshed with a cable pulley in one row (the upper row in the figure), and the inner surface of the chain is meshed with a cable pulley in another row (the lower row in the figure), so that the linear speeds of the opposite surfaces of the two cable pulleys are consistent in magnitude and direction. Inside the chain are the transmission output shaft 1031, the tensioning wheel 4041, and the shaft 4021 of a cable pulley in the lower row. The shaft of a cable pulley in the upper row is located on the outer surface of the chain. The transmission output shaft, the tensioning wheel 4041, and the shaft 4021 of a cable pulley in the lower row are each a point of a triangle to tighten the chain. There are guide wheels 22 at the front and rear of the cable pulley row, respectively, so that the cable can enter and exit the crawler on the surface of the cable pulley in a relatively straight manner.

[0038] The cable puller is composed of multiple cable pulling power wheels. The overall pulling force is large, the pulling force of a single cable pulling power wheel is small, and the damage to the cable is small. Generally, a cable puller is arranged every 100-800 meters.

[0039] There are many types of cable pay-off devices that match the cable pulling device of the present invention, such as Figure 1 , 6As shown in Figures 7 and 8, a vertical cable pay-off device is shown, which consists of a floor bracket 1, a transmission device 2, a load-bearing turntable 3, a brake gear ring 4, a brake 5, a sensor encoder 7, a sensor encoder bracket 6, a power supply 8, an anti-loosening device 9, and a control system. The brake used is an electromagnetic brake. The control system is electrically connected to the power supply, the sensor encoder, and the electromagnetic brake respectively. There are 3-4 supporting feet 11 at the bottom of the floor bracket. There are 4 supporting feet in the figure with equal circumferential angles. The top surface of the supporting feet is inclined from high to low from inside to outside. On the basis of ensuring the stability of the overall device, the overall weight can be reduced. There is a central axis tube 12 in the center of the floor bracket for installing and fixing the load-bearing turntable, the cable drum, and the anti-loosening device. The brake gear ring is a hollow ring, and the inner ring is a gear. The hollow brake gear ring is welded under the load-bearing turntable. The two are concentric and linked. The electromagnetic brake has a gear that matches the brake gear ring. The two are meshed to realize the connection between the electromagnetic brake and the brake gear ring. The radius of the brake gear ring is greater than the radius of the electromagnetic brake gear, and the radius of the brake gear ring is 4-20 times the radius of the electromagnetic brake gear. The sensor encoder is fixed on the sensor encoder bracket, and the sensor encoder bracket 6 is fixed to the floor bracket by bolts. The overall volume is small and easy to disassemble and assemble. When in use, the sensor encoder bracket 6 is placed in the direction of the outlet. A transmission device 2 is connected above the sensor encoder. The transmission device 2 is composed of a base plate 21, a guide wheel 22, and a transmission wheel 23. The transmission wheel is a concave waist drum wheel. The guide wheel can be the same as the transmission wheel to reduce the model of parts. The concave waist drum wheel can ensure that the cable does not separate from the waist drum wheel. The rectangular base plate is fixed on the sensor encoder bracket, and four guide wheels are fixed above the base plate. The center line of the four guide wheels is a rectangle similar to the base plate, wherein the spacing between the two guide wheels on the short side is not greater than 2 times the outer diameter of the cable. The center of the transmission wheel is on the midline of the long side of the base plate. The center of the rectangle formed by the center of the transmission wheel and the center of the four guide wheels does not overlap, and the rotating shaft of the transmission wheel is connected to the sensor encoder. The eccentricity of the center of the rectangle formed by the center of the transmission wheel and the center of the four guide wheels is adjustable to meet the needs of cables with different wire diameters. The radius of the transmission wheel is R, and the eccentricity of the center of the rectangle formed by the center of the transmission wheel and the center of the four guide wheels is 1 / 2-2R.

[0040] When in use, the cable passes through the transmission device connected to the top of the sensor encoder and then is pulled out. The cable 10 passes through the middle of the two guide wheels 22 on the short side, bypasses the outside of the transmission wheel 23, and is pulled out from the middle of the guide wheel at the other end. The eccentric transmission wheel applies pressure to the cable side, so that the cable can drive the transmission wheel to rotate when it moves forward. The transmission wheel of the transmission device converts the linear motion of the cable into a rotation signal and transmits it to the sensor encoder. When the cable is pulled normally, the electromagnetic brake rotates with the brake gear ring without resistance. When the sensor encoder senses that the speed of the cable in front decreases or stops moving, it transmits a signal to the control system. The control system controls the electromagnetic brake to generate magnetic forces of different sizes to attract the brake gear ring, so that the rotation speed of the brake gear ring decreases or stops, thereby reducing or stopping the rotation speed of the load-bearing turntable and cable drum that move together.

[0041] The anti-loosening device 9 is composed of a fixed rod 91, an elastic pressure rod 92, a reinforcing rod 94, and a pipe sleeve 93. The fixed rod is connected to the floor bracket or the sensor encoder bracket, the elastic pressure rod is connected to the fixed rod, the height of the elastic pressure rod is not greater than the width of the cable wound in the cable drum, the reinforcing rod is connected to the pipe sleeve, the other end of the reinforcing rod is connected to the top of the fixed rod, and the pipe sleeve is sleeved with the central axis tube. When in use, after the cable drum is placed in the load-bearing turntable, the pipe sleeve is inserted into the central axis tube, and the other end of the reinforcing rod is connected to the top of the fixed rod to enhance the stability of the fixed rod. The elastic pressure rod is always pressed on the outer surface of the cable of the cable drum to prevent the cable from slipping down.

[0042] Embodiment 2, as Fig. 9 Another vertical cable pay-out device is shown, which is composed of a floor stand 1, a load-bearing turntable 3, a brake 5, and a controller 300. The cable pulling device and the cable pay-out device use a controller of the same structure, but the rear ends connected to the controller are different. The controller of the cable pulling device controls the clutch, and the controller of the cable pay-out device is connected to the motor of the brake.

[0043] A brake gear ring is fixed below the load-bearing turntable. The brake gear ring 4 is welded to form an integral body with the load-bearing turntable. The brake cooperates with the brake gear ring. The brake has a gear 503 that cooperates with the brake gear ring. The radius of the brake gear ring is greater than the radius of the gear of the brake. The radius of the gear inside the brake gear ring is 4-20 times the radius of the gear of the brake. There is a central axis tube 12 at the center of the floor bracket. The load-bearing turntable is fixed to the outside of the central axis tube through a bearing. The brake gear is connected to the brake motor and is located below the brake gear ring. The structure of the controller is the same as that of the controller of the cable pulling device, except that the controlled object and signal are different. The controller 300 is located in front of the floor bracket. The controller is electrically connected to the brake motor. The speed sensor transmits the movement speed of the cable to the controller. The controller controls the brake motor according to the movement speed of the cable, thereby controlling the rotation speed of the gear 503. When the cable is pulled normally, the brake rotates with the brake gear ring without resistance. The remaining undescribed parts are the same as those in Example 1.

[0044] Embodiment 3, as Fig.10 , 11 As shown, a horizontal cable unwinding device matched with a cable pulling device is formed by load-bearing brackets on both sides, a central axis 501, a turntable 502 with a brake gear ring 4 fixed on the back, a brake 5, and a controller 300. The controller is electrically connected to the brake. The first load-bearing bracket 504 is formed by two supporting legs 505 fixed on the outside of a first central axis tube seat 506, and the second load-bearing bracket 507 is formed by two supporting legs 505 fixed on the outside of a second central axis tube seat 508. The turntable is fixed on one side of the second central axis tube seat, and a reinforcing rod 5051 is fixed between the two supporting legs to enhance the strength and rigidity of the supporting legs. The supporting foot is composed of a screw tube 5052 and a bolt foot 5053, so that the height of the supporting foot can be adjusted to adapt to uneven ground and cable drums of different diameters. The angle between the two supporting feet is 10-60 degrees, and 15-20 degrees is selected in this example. The vertical height of the two supporting feet after standing is not less than the center height of the cable drum in the horizontal state. In this way, it can be ensured that after the cable drum is fixed to the central axis, the cable drum leaves the ground as a whole and can rotate freely. Since there is a turntable and a brake on one side of the second central axis tube seat, its length and load-bearing capacity are greater than those of the first central axis tube seat, so two bearings 509 and a retaining ring 5081 are installed inside the second central axis tube seat. The retaining ring is located between the two bearings to position the axial direction of the bearing. A turntable shaft 5082 fixed to the turntable 502 is sleeved in the bearing. The brake turntable shaft 5082 is a hollow cylindrical shaft tube with a top larger than the middle. The convex edge is welded and fixedly connected with the brake disc, and its surface is preferably flush with the surface of the brake disc. Its size is adapted to the structure of the cable drum center hole, so as not to affect the connection function of the protrusion on the surface of the brake disc. The inner surface of the rear end of the brake disc shaft is processed with a thread, and the end of the middle shaft is processed with an external thread that matches the brake disc shaft, so that the two are connected. A through pin hole is processed at the rear end of the middle shaft. After the middle shaft is fixed in place, a pin 5083 is inserted to prevent the middle shaft from loosening and falling out. A slotted nut 5084 can also be added to make the connection between the middle shaft and the turntable shaft more stable, so that the middle shaft rotates simultaneously with the turntable shaft. The side of the turntable 502 that contacts the cable drum is a disk that is not less than the diameter of the cable drum. A plurality of protrusions 5021 are made on the surface, which can be arranged on the surface at will. There are 8 protrusions in the figure, which are evenly distributed along the circumference and can be made of steel nails or screws. When the cable drum is fixed, the protrusion on the brake disc is embedded in the cable drum, becoming a connecting piece that the cable drum and the brake disc rotate together, and the two can also be fixed by bolts. In this way, the rotation between the central shaft and the cable drum, in addition to the existing linkage structure, also increases the linkage between the cable drum and the surface of the brake rotary disc.

[0045] The back of the turntable is welded with the brake gear ring 4, and the brake is fixed on the reinforcing rod of the support foot of the second central axis tube seat. A support platform for fixing the brake can be made on the reinforcing rod, so that the brake is stably and firmly supported. The brake 5 is matched with the turntable, and the brake has a gear 503 matched with the turntable. The radius of the brake gear ring is greater than the radius of the gear of the brake, and the radius of the gear inside the brake gear ring is 4-20 times the radius of the gear of the brake. A rear end cover 5023 is fixed on the second central axis tube seat at the rear end of the turntable.

[0046] The first central axis tube seat 506 is provided with a bearing 509, and the locking pressure plate 5061 is installed in the first central axis tube seat 506 through the bearing.
