Description

Technical Field

[0001] The present invention relates to the technical field of detecting sample transportation, and particularly relates to a load-carrying climbing transportation device. Background Art

[0002] As an important industrial material in modern production, ribbed steel has a wide range of applications in industries such as construction, machinery, transportation, etc. If the relevant dimensions of its transverse ribs and longitudinal ribs on the surface cannot meet the requirements of national standards, they will be regarded as dimensional defects, and the products will definitely be unqualified. With the increasing market requirements for the surface quality of ribbed steel, the machine vision system module is used to measure the length to improve the accuracy and reduce the manual measurement error. The automatic weighing system can quickly and accurately measure the weight. After the automatic analysis system analyzes the data, the workers can adjust the rolling mill according to the deviation value in the first time, improving the work efficiency.

[0003] Before detection, the cut-off heads on the cooling bed need to be sent for inspection, and the cut-off heads are transported to the detection laboratory or the inside of the weight per meter detector by manual means for detection.

[0004] When the existing ribbed steel cut-off head samples are sent for inspection, the ribbed steel cut-off head samples are transported to the detection laboratory or the weight per meter detector by manual transportation, which requires manual conveyance. It wastes manpower and also wastes a large amount of inspection time, making it unable to efficiently adjust the rolling mill according to the analyzed data. Therefore, the present application provides a load-carrying climbing transportation device to meet the requirements. Summary of the Invention

[0021] As Figures 1 to 5 shown, an embodiment of the present invention provides a load-carrying climbing transportation device, including a handrail track 1, on which a track robot 3 is slidably connected. Both the handrail track 1 and the track robot 3 are prior arts. The handrail track 1 provides a running track for adapting to the track robot 3 and at the same time serves as a handrail for a staircase. A bottom end of the track robot 3 is fixedly connected with an L-shaped connecting rod 31. Through the L-shaped connecting rod 31, a threaded steel cutting head sample towed on an embedding block 32 can be separated from the lower part of the handrail track 1 by a certain distance, avoiding collision between the threaded steel cutting head sample and the lower part of the handrail track 1. One end of the L-shaped connecting rod 31 is fixedly connected with the embedding block 32, and a towing structure 8 is fixedly sleeved on an outer wall of the embedding block 32. The embedding block 32 is used for fixedly connecting the towing structure 8. During the movement of the track robot 3 on the handrail track 1, the connected towing structure 8 can be driven to move synchronously, and then the sample moving device 6 on the AGV cart 4 is towed through the towing structure 8, driving the sample placing device 7 with the threaded steel cutting head sample placed thereon to move on the handrail track 1, so as to carry the threaded steel cutting head sample to a detection area for quality detection of the threaded steel cutting head sample.

[0022] There is a support platform 2 below the handrail track 1. A guiding magnetic strip 21 is laid on the surface of the support platform 2. The guiding magnetic strip 21 is used to provide a traveling guiding track for the AGV cart 4. There is an AGV cart 4 moving along the trajectory of the guiding magnetic strip 21 on the surface of the support platform 2. The AGV cart 4 is a prior art. The cold bed sampling robot samples the cut head samples of the deformed steel bars in the sample collection area on the cold bed. After the cold bed sampling robot samples, it places the cut head samples of the deformed steel bars on the AGV cart 4, and then the track robot 3 transports the cut head samples of the deformed steel bars to the testing laboratory or the weight per meter tester room. On both sides of the support platform 2 close to the guiding magnetic strip 21, there are fixedly connected guiding partitions 22. The guiding partitions 22 are used to prevent the AGV cart 4 from running off course when approaching below the track robot 3 and avoid the situation of deviation when the traction structure 8 is docked with the sample moving device 6. On one side surface of the AGV cart 4 close to the bottom end of the traction structure 8, there is a switch. When the AGV cart 4 moves below the traction structure 8, the traction structure 8 will press the switch, thereby turning on the switch and controlling the operation of the adjustment motor 55 and the cylinder 9. At the central position on the surface of the AGV cart 4, there is a lifting groove 42. The lifting groove 42 is used to provide a lifting space for the lifting housing 41 and the limiting device 5. At the inner bottom end of the AGV cart 4 close to the lifting groove 42, there is fixedly connected a cylinder 9. The cylinder 9 is used to realize the lifting of the lifting housing 41 fixed at its top end and the limiting device 5 fixed on the lifting housing 41. When the limiting device 5 releases the limit on the sample moving device 6, the cylinder 9 drives the limiting device 5 and the lifting housing 41 to descend, thereby placing the entire sample moving device 6 on the traction structure 8 and avoiding the influence of the limiting device 5 and the lifting housing 41 on the traction work of the traction structure 8 on the sample moving device 6. The outer surface of the output end of the cylinder 9 is fixedly connected with a lifting housing 41. The lifting housing 41 is adapted to the lifting groove 42. When the lifting housing 41 is in the initial position, the lifting housing 41 can close the lifting groove 42 to avoid sundries or dust entering the inside of the AGV cart 4 and causing the failure of its internal system. On one side surface of the lifting housing 41, there is fixedly connected a limiting device 5. The limiting device 5 is used to limit and fix the sample moving device 6. When transporting the cut head samples of the deformed steel bars, the limiting device 5 always locks the sample moving device 6. When the sample moving device 6 is docked with the traction structure 8, the limiting device 5 releases the limit on the sample moving device 6, so that the traction structure 8 can, under the operation of the track robot 3, traction and transport the sample moving device 6 into the sample testing laboratory. On one side surface of the limiting device 5, there is detachably connected a sample moving device 6. On both sides of the top end of the sample moving device 6, there are fixedly connected sample placing devices 7. The bottom end of the sample moving device 6 is adapted to the limiting device 5, and the top end provides an installation platform for the sample placing devices 7. The sample placing devices 7 can place cut head samples of deformed steel bars with multiple diameter sizes, and the placing method is simple, which is convenient for the cold bed sampling robot to directly place after sampling without manual placement by staff.A detachable connection structure is also provided between the sample moving device (6) and the traction structure (8). Through the connection structure, the locking between the traction structure 8 and the sample moving device 6 can be achieved; through the mutual cooperation of the cylinder 9, the limiting device 5, the sample moving device 6, the sample placing device 7 and the traction structure 8, the docking between the AGV cart 4 and the rail robot 3 is realized. The AGV cart 4 transports the support platform 2 for the cut head samples of the deformed steel bars, and the rail robot 3 transports the cut head samples of the deformed steel bars on the slope, thereby realizing the transportation of the cut head samples of the deformed steel bars from the sample collection area on the cooling bed to the sample testing laboratory or the weight per meter testing room, without manual transportation, greatly saving the transportation time and labor costs.

[0023] Such as Figure 6 And Figure 7As shown in the figure, the limiting device 5 includes a cross 51 fixed to one side surface of the lifting housing 41. A cross groove 512 is formed inside the cross 51. The cross groove 512 provides an installation space for the operating structure. Limiting sliding grooves 511 communicating with the cross groove 512 are formed on both end surfaces of the cross 51. The limiting sliding grooves 511 are used to provide a sliding track for the slider 521 and can limit the slider 521 at the same time. A motor installation groove 513 is formed at the center position of the cross groove 512. The motor installation groove 513 is used to provide an installation space for the motor. Chassis limiting blocks 52 are provided on both end surfaces of the cross 51, and stoppers 56 are fixedly connected to the other two end surfaces of the cross 51. The distance between the two stoppers 56 is the same as the diameter of the moving chassis 61. When the two chassis limiting blocks 52 are in the initial position, the distance between them is smaller than the diameter of the moving chassis 61. The chassis limiting blocks 52 are used to detachably fix the moving chassis 61, and the stoppers 56 are used to resist and limit the moving chassis 61 placed on the cross 51. A slider 521 is fixedly connected to the bottom end of the chassis limiting block 52. The slider 521 is used to connect the chassis limiting block 52 and the sliding base 53, so that when the sliding base 53 moves, it can drive the chassis limiting block 52 to move accordingly. The chassis limiting block 52 slides in the limiting sliding groove 511 through the slider 521. Limiting openings 522 are formed on the opposite sides of the two chassis limiting blocks 52. The limiting openings 522 are semi-circular arc structures adapted to the moving chassis 61. The two ends of the moving chassis 61 are clamped into the limiting openings 522, and then the edge of the moving chassis 61 is resisted by the stoppers 56, so as to limit and fix the moving chassis 61. It further includes an operating structure for the chassis limiting block 52 to slide in the limiting sliding groove 511. The operating structure is used to control the expansion of the two chassis limiting blocks 52, so as to release the limitation of the moving chassis 61. The operating structure includes sliding bases 53 slidably connected to both ends inside the cross groove 512. The sliding bases 53 are used to drive the chassis limiting blocks 52 to slide synchronously. A sliding limiting rod 531 is fixedly connected to one side surface of the sliding base 53. One sliding limiting rod 531 is connected to one sliding base 53, and the other sliding limiting rod 531 is connected to the other sliding base 53. It should be noted here that the two sliding limiting rods 531 are arranged opposite to each other, that is, when the rotating gear 551 rotates, the two sliding limiting rods 531 move relatively, driving the two sliding bases 53 to slide outward. Limiting teeth 532 are formed on the opposite side surfaces of the two sliding limiting rods 531. The sliding limiting rod 531 is engaged with the rotating gear 551 through the limiting teeth 532 to realize the transmission of the sliding base 53. A first limiting slide rod 514 and a second limiting slide rod 515 are respectively fixedly connected to both ends of the bottom surface of the cross groove 512 close to the sliding limiting rod 531. The first limiting slide rod 514 and the second limiting slide rod 515 have the same specifications. The sliding limiting rod 531 is slidably connected inside the first limiting slide rod 514 and the second limiting slide rod 515. The first limiting slide rod 514 and the second limiting slide rod 515 limit the sliding limiting rod 531.A return spring 54 is connected between the opposite side surfaces of the sliding base 53 and the second limit slide bar 515. The return spring 54 is used to pull the sliding base 53. Under the traction force of the return spring 54, the two chassis limit blocks 52 can squeeze and limit the moving chassis 61. The bottom surface of the motor mounting groove 513 is fixedly connected with an adjustment motor 55. The output end of the adjustment motor 55 is fixedly connected with a rotating gear 551. The rotating gear 551 is meshed with the two sliding limit rods 531. When installing the sample moving device 6, press the switch, and the adjustment motor 55 starts to work. The rotation of its output shaft drives the connected rotating gear 551 to rotate. When the rotating gear 551 rotates, it drives the sliding limit rod 531 meshed with it, and then drives the sliding base 53 connected to the sliding limit rod 531 to slide outward, thereby driving the two chassis limit blocks 52 to expand outward. At this time, the moving chassis 61 is placed inside the two chassis limit blocks 52 and the two stoppers 56, and then the switch is turned off. The adjustment motor 5 is a stepper motor. When the adjustment motor is powered off, its rotor can rotate under the action of an external force. Therefore, when the adjustment motor 55 stops working, the two sliding bases 53 move inward under the reset force of the return spring 54, and then drive the chassis limit blocks 52 to move. The limit ports 522 on the chassis limit blocks 52 are clamped into the edge of the moving chassis 61, thereby limiting and fixing the moving chassis 61.,

[0024] As Figure 8 、 Figure 11 and Figure 12As shown, the sample moving device 6 includes a moving chassis 61 snap-connected between two chassis limit blocks 52. The moving chassis 61 is a disc structure with a semi-circular arc at the edge. A support block 64 is fixedly connected to the center position of the surface of the moving chassis 61. The support block 64 is used to install the connection structure. A placement mounting plate 63 is fixedly connected to one side surface of the support block 64. The placement mounting plate 63 provides an installation platform for the sample placement device 7. The connection structure includes a ratchet mounting groove 641 opened inside the support block 64. The ratchet mounting groove 641 provides an installation platform for the ratchet 65 and the pawl 66. Two mutually meshing ratchets 65 are rotatably connected inside the ratchet mounting groove 641. A pawl 66 is rotatably connected to the outer surface of the ratchet mounting groove 641 near one of the ratchets 65. The two ratchets 65 can only rotate unidirectionally through the pawl 66. One end of the pawl 66 is connected to an adjustment pull rod 661. The top end of the pawl 66 can be pulled through the adjustment pull rod 661, so as to adjust the direction of the pawl 66, and thus adjust the rotation direction of the ratchet 65. Plug pipes 62 are fixedly connected to both side surfaces of the support block 64. The plug pipes 62 are used for the insertion of the plug rod 83. The plug rod 83 is inserted into the plug rod groove 623 on the plug pipe 62 until the plug teeth 831 on the plug rod 83 slide on the docking interface 624 and the ratchet 65 until one end of the plug rod 83 passes through the inside of the plug rod groove 623, so as to realize the fixation of the plug rod 83 and the plug pipe 62. A sector block 621 is fixedly connected to one end of the plug pipe 62. A plug rod groove 623 and a sector groove 622 which are communicated with each other are respectively opened inside the plug pipe 62 and the sector block 621. The sector groove 622 is used to facilitate the insertion of the plug rod 83, avoiding the situation that the docking between the plug rod 83 and the plug rod groove 623 fails due to the deviation of the stopping position of the AGV cart 4. And a docking interface 624 communicated with the ratchet mounting groove 641 and the plug rod groove 623 is opened on one side of the plug pipe 62 close to the ratchet mounting groove 641. The plug pipe 62 and the plug rod 83 are connected by meshing cooperation of the ratchet 65 and the plug teeth 831. The width of the plug rod groove 623 is the same as the width of the plug rod 83. When the traction structure 8 pulls the sample moving device 6, the plug rod 83 on the traction structure 8 enters the inside of the plug rod groove 623 along the sector groove 622. When the top end of the plug rod 83 passes through the plug rod groove 623, the plug teeth 831 on the plug rod 83 mesh with the ratchet 65. And under the limitation of the pawl 66, the plug rod 83 is limited and cannot be pulled out. Then, under the traction of the track robot 3, the traction structure 8 drives the sample moving device 6 to move towards the detection laboratory or the weight meter measurement room.

[0025] As Figure 4 and Figure 12As shown in the figure, the traction structure 8 includes a traction seat 81 fixed to one side surface of the embedded block 32. The traction seat 81 is used to install a contact plate 82 and a plug rod 83. The bottom end of the traction seat 81 is fixedly connected with a contact plate 82. The contact plate 82 is an arc-shaped plate, and the bottom surface of the arc-shaped plate is smooth. During the movement of the AGV cart 4, the contact plate 82 gradually comes into contact with the switch. Until the AGV cart 4 moves to the preset position, the bottom end of the contact plate 82 just presses the switch to turn it on. At the same time, one end of the contact plate 82 away from the traction seat 81 is a vertical plane. When the AGV cart 4 moves to the preset position, one end of the contact plate 82 just abuts against the side surface of the cross 51, so that the contact plate 82 is just located above the switch. A plug rod 83 is fixedly connected to one side of the traction seat 81 close to the AGV cart 4. Insertion teeth 831 are provided on the opposite sides of the two plug rods 83.

[0026] As Figures 8 to 10As shown, the sample placement device 7 includes semi-circular mounting plates 71 fixedly connected to the two end surfaces of the placement mounting plate 63. The semi-circular mounting plates 71 are used to fixedly mount the sample placement pieces 72. The inner wall of the semi-circular mounting plates 71 is fixedly connected with the sample placement pieces 72. The two sample placement pieces 72 are used to fix the rebar cutting head samples. A number of rubber strips 73 are evenly fixed on the surface of the sample placement piece 72. The rubber strips 73 can increase the friction with the rebar cutting head samples, so that when the AGV cart 4 transports the rebar cutting head samples, the rebar cutting head samples will not fall off. The sample placement piece 72 is connected by a fixed section 721, two wrapping sections 722, two first deformation sections 723, two connecting sections 724, two second deformation sections 725 and two extension sections 726. The outer wall of the fixed section 721 is fixedly connected with the inner wall of the semi-circular mounting plate 71. The two ends of the fixed section 721 are connected with the connecting sections 724. One end of the connecting section 724 is connected with the second deformation section 725. One end of the second deformation section 725 is connected with the extension section 726. The wrapping section 722 is connected inward at the connection position between the connecting section 724 and the fixed section 721. The first deformation section 723 is connected to the surface at the connection position between the wrapping section 722 and the connecting section 724. The thickness of the first deformation section 723 gradually changes from thick to thin from the middle to both sides. The thickness of the wrapping section 722 gradually changes from thin to thick from the end close to the connecting section 724. The semi-circular mounting plate 71 and the sample placement piece 72 are integrally formed by die-casting. Die-casting integrally forming has advantages such as high production efficiency, high product precision, good product quality and low production cost. When the diameter of the rebar cutting head sample to be placed is small, the cold bed sampling robot grabs the rebar cutting head sample and transfers it to the sample placement device 7, so that the two ends of the rebar cutting head sample are on the two extension sections 726 of the sample placement device 7. Under the extrusion of the cold bed sampling robot, the rebar cutting head sample is extruded from the second deformation section 725, so that the fixed section 721 expands outward, so that the rebar cutting head sample enters above the wrapping section 722, and then continues to be extruded, so that the outer wall of the rebar cutting head sample extrudes the first deformation section 723, and the first deformation section 723 is extruded and compressed and deformed until the outer wall of the rebar cutting head sample is in contact with the inner wall of the wrapping section 722. At the same time, the second deformation section 725 recovers its deformation and limits and fixes the outer wall of the rebar cutting head sample. When the diameter of the rebar cutting head sample to be placed is large, after the rebar cutting head sample fits with the inner wall of the wrapping section 722, continue to extrude the rebar cutting head sample, so that the rebar cutting head sample drives the wrapping section 722 to deform until the wrapping section 722 fits with the fixed section 721. When the rebar cutting head sample extrudes the wrapping section 722 to fit with the fixed section 721, the rebar cutting head sample will disengage from extruding the first deformation section 723. After the first deformation section 723 recovers its deformation, it will limit and fix the outer wall of the rebar cutting head sample. Through the mutual cooperation of the wrapping section 722, the first deformation section 723 and the second deformation section 725,The sample placement sheet 72 can be adapted to rebar cut samples of multiple sizes.

[0027] The working principle provided by the present invention is as follows. When it is necessary to transport the rebar cut sample from the sample collection area on the cooling bed to the sample detection laboratory, the sample moving device 6 carrying the sample placement device 7 is installed on the limiting device 5 of the AGV cart 4. When installing the sample moving device 6, press the switch, and the adjustment motor 55 starts to work. The output shaft rotates to drive the connected rotating gear 551 to rotate. When the rotating gear 551 rotates, it drives the sliding limiting rod 531 engaged with it, and then drives the sliding base 53 connected to the sliding limiting rod 531 to slide outward, thereby driving the two chassis limiting blocks 52 to expand outward. At this time, the moving chassis 61 is placed inside the two chassis limiting blocks 52 and the two stoppers 56, and then the switch is turned off, and the adjustment motor 55 stops working. The two sliding bases 53 then move inward under the restoring force of the restoring spring 54, and then drive the chassis limiting blocks 52 to move. The limiting ports 522 on the chassis limiting blocks 52 are stuck into the edge of the moving chassis 61, thereby limiting and fixing the moving chassis 61 on the sample moving device 6.

[0028] Then, place the rebar cut sample on the sample placement device 7. When the diameter of the rebar cut sample to be placed is small, the cooling bed sampling robot grabs the rebar cut sample and transfers it to the sample placement device 7, so that both ends of the rebar cut sample are on the two extension segments 726 of the sample placement device 7. Under the extrusion of the cooling bed sampling robot, the rebar cut sample is extruded from the second deformation segment 725, so that the fixed segment 721 expands outward, so that the rebar cut sample enters above the wrapping segment 722, and then continues to be extruded, so that the outer wall of the rebar cut sample extrudes the first deformation segment 723, and the first deformation segment 723 is extruded and compressed and deformed until the outer wall of the rebar cut sample is in contact with the inner wall of the wrapping segment 722. At the same time, the second deformation segment 725 returns to its original shape and limits and fixes the outer wall of the rebar cut sample. When the diameter of the rebar cut sample to be placed is large, after the rebar cut sample fits with the inner wall of the wrapping segment 722, continue to extrude the rebar cut sample, so that the rebar cut sample drives the wrapping segment 722 to deform until the wrapping segment 722 fits with the fixed segment 721. When the rebar cut sample extrudes the wrapping segment 722 to fit with the fixed segment 721, the rebar cut sample will disengage from the extrusion of the first deformation segment 723. After the first deformation segment 723 returns to its original shape, it will limit and fix the outer wall of the rebar cut sample.

[0029] After the ribbed steel cutting head sample is fixed, the AGV cart 4 transports the ribbed steel cutting head sample along the route of the guiding magnetic strip 21 until the AGV cart 4 is transported between the guiding partitions 22. When the AGV cart 4 moves within the guiding partitions 22, the insertion rod 83 on the rail robot 3 equipped with the traction structure 8 enters into the insertion rod slot 623 along the fan-shaped slot 622. When the top end of the insertion rod 83 passes through the insertion rod slot 623, the insertion teeth 831 on the insertion rod 83 are engaged with the ratchet wheel 65, and under the limit of the pawl 66, the insertion rod 83 is limited. At the same time, when the AGV cart 4 moves to the preset position, one end of the contact plate 82 just abuts against the side surface of the cross 51, so that the contact plate 82 is just located above the switch. The contact plate 82 gradually contacts with the switch until the bottom end of the contact plate 82 just presses the switch to turn on the switch.

[0030] After the switch is turned on, the control adjustment motor 55 starts to work, so that the two chassis limit blocks 52 release the limit on the moving chassis 61. At the same time, the air cylinder 9 drives the lifting outer shell 41 and the limiting device 5 fixed on the lifting outer shell 41 to contract. At this time, the sample moving device 6 is completely fixed on the insertion rod 83. The laboratory personnel control the rail robot 3 to move along the handrail track 1 until it moves to the detection laboratory or the weight per meter measuring room. Then the staff takes out the ribbed steel cutting head sample for quality inspection, and the AGV cart 4 repeats the above actions to transport the next sample.

[0031] The above is only used to illustrate the technical solution of the present invention and not to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
