Description

Technical Field

[0001] The present invention belongs to the technical field of cable transportation, and particularly relates to a storage and transfer device for heavy cable semi-finished products. Background Art

[0002] Currently in the cable production industry, heavy (3 - 10 tons) cable semi-finished products are transported by overhead cranes, and the transfer efficiency is not high. At the same time, due to the use of overhead cranes, certain unsafe factors are added to the cable production process. Moreover, the hoisting process of overhead cranes requires manual assistance to hook and tie tightly, making it difficult to achieve automation and intelligence. In addition, due to the presence of overhead cranes, the construction cost and space cost of the entire factory building become higher, and the cost of expanding production scale is high.

[0003] Currently, during the transfer process of heavy-duty cable semi-finished products, alternative tools for overhead cranes include heavy-duty AGVs, automatic forklifts, etc. However, heavy-duty AGVs integrate load and traction, are too large in size, cannot effectively move in the existing cable production workshops, and are expensive. Automatic forklifts require a large counterweight and have a large turning radius, making it difficult to effectively achieve flexible transfer of semi-finished products, and also having the cost disadvantage of high price. Therefore, it is necessary to design a cable semi-finished product storage and transfer system with separated load and traction to fill the market gap.

[0004] The Chinese utility model patent "A Transfer Device for Cable Production" (Publication No.: CN214217702U) discloses a transfer device for cable production, including a base. Universal wheels are provided at the four corners of the bottom of the base. Two symmetrically arranged damping bases are provided above the base. The base is connected to the damping base through several telescopical rods arranged in an array, and a longitudinal damping spring is sleeved outside the telescopical rod. A vertical plate is perpendicularly connected above each damping base, and several electric push rods corresponding to each other in position are provided on one side of the two vertical plates facing each other. The end of the electric push rod away from the vertical plate is connected to a support rod through a limiting plate. A damping plate is sleeved outside the support rod, and a transverse damping spring is sleeved outside the support rod between the limiting plate and the damping plate. However, this utility model focuses on the positioning of the cable reel, improving the installation stability of the cable reel and the damping effect, and cannot achieve the separation of load and traction.

[0005] The Chinese invention patent "A Power Cable Transfer Device" (Publication No.: CN112225016A) discloses a power cable transfer device, which includes a frame. A moving wheel is fixedly connected to the bottom of the frame. A push handle is fixedly connected to the right side of the frame. A load-bearing plate is slidably connected to the inner wall of the frame. A fixed plate is fixedly connected to the inner wall of the frame. A self-fixing mechanism is arranged at the bottom of the load-bearing plate. A cable reel is placed on the upper surface of the load-bearing plate. A clamping mechanism is arranged on the right side of the load-bearing plate. The invention focuses on that due to the influence of the gravity of the cable reel on the load-bearing plate, the load-bearing plate will descend, and the rotating gear will drive the feeding plate to rotate and retract, so that during the movement of the whole device, the two feeding plates will not interfere, providing good yielding, thereby realizing automatic fixation during the cable transfer process, eliminating the need for manual bundling and installation, reducing labor intensity, and improving the stability during its movement. However, the separation of load and traction is not involved. Summary of the Invention

[0006] The object of the present invention is to provide a heavy-duty cable semi-finished product warehousing and transfer device for the deficiencies of the above-mentioned existing technologies, and to realize the separation of the load and traction of the cable through the cable semi-finished product warehousing and transfer system.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is:

[0008] The heavy-duty cable semi-finished product warehousing and transfer device includes a driving vehicle and a disk seat that are separately arranged, and the driving vehicle is located at the bottom of the disk seat and is detachably assembled with the disk seat;

[0009] The driving vehicle includes a driving device, a detection system, side telescopic plates, and a hollow connecting column protruding from the side telescopic plates. The side telescopic plates are symmetrically arranged and can extend to both sides. The detection system is arranged inside the hollow connecting column;

[0010] The disk seat includes a load-bearing beam, load-bearing universal wheels rotatably arranged at the bottom of the load-bearing beam, telescopic arms, and safety legs. A support groove is formed on the load-bearing beam. The telescopic arms are connected between the symmetrically arranged load-bearing beams and the distance between them is adjustable;

[0011] The safety leg includes a safety leg housing fixedly arranged under the load-bearing beam and a telescopic safety foot installed inside the safety leg housing. The telescopic safety foot moves up and down inside the safety leg housing and can move upward to be in a walking state or move downward to be in a supporting state;

[0012] A control window and a connection hole corresponding to the connecting column are also formed on the safety leg housing. The driving vehicle controls the connecting column to insert into or disengage from the connection hole to assemble or separate from the disk seat.

[0013] An up-and-down moving device is further provided inside the side telescopic plate. An induction control device that moves synchronously with it is provided on the up-and-down moving device, and the induction control device is arranged horizontally.

[0014] The induction control device includes a control hook located outside the side telescopic plate and a side pressure sensor located inside the side telescopic plate, and the two are connected by a control tongue.

[0015] The control hook is used to control the lifting of the telescopic safety foot.

[0016] The telescopic safety foot includes a safety foot seat, a spring frame fixed on the safety foot seat, and a transmission rod frame fixed on the spring frame. A transmission rod is also rotatably connected to the top of the transmission rod frame, and a support block group is provided at the bottom of the transmission rod.

[0017] The support block group includes an outer support block and an inner support block arranged symmetrically at intervals. The two are fixedly connected by a connecting strip located below them, and the inner support block is rotatably connected to the bottom end of the transmission rod. The spring frame is arranged side by side between the outer support block and the inner support block, and a return spring is also connected between the spring frame and the inner support block.

[0018] A sliding groove for sliding an internal connecting strip is also opened on the safety foot seat, and the length of the connecting strip is set to be equal to the width of the sliding groove.

[0019] When the control hook of the driving vehicle pushes the transmission rod through the control window, the transmission rod drives the support block group to move outward and compress the return spring. After the support block group moves outward, a gap appears between the safety leg housing and the telescopic safety foot, and the safety foot seat is lifted upward to be in a walking state.

[0020] When the control hook of the driving vehicle disengages from the transmission rod and moves downward, the telescopic safety foot extends downward under the action of gravity. The return spring drives the support block group to move inward and return, and at the same time drives the transmission rod to move inward. After the support block group moves outward, the safety foot seat moves downward to be in a supporting state.

[0021] A lifting groove and a safety groove are also provided on the transmission rod from top to bottom. The lifting groove is set as an inclined groove inclined inward, and the safety groove is set as a rectangular groove and its depth is greater than the depth of the lifting groove.

[0022] The up-and-down moving device adopts a rack and pinion meshing transmission, and the pinion is installed inside the side telescopic plate and rotates under the action of a motor. A sliding holding groove is also fixedly provided inside the side telescopic plate. After meshing with the pinion, the rack moves up and down in the sliding holding groove, and the control tongue passes through the rack and drives the control hook to move up and down synchronously with the rack outside the side telescopic plate.

[0023] An inwardly U-shaped pressure sensing frame is also fixed inside the side telescopic plate. The pressure sensing frame is located between the rack and the side pressure sensor, and auxiliary pressure sensors for measuring vertical pressure are provided at both ends of the pressure sensing frame.

[0024] The detection system includes a camera device and a ranging sensor, and the detection system is connected to the driving device in a control manner and extends out of both sides of the turntable seat through the connection holes on the safety legs for information sensing.

[0025] The side telescopic plate moves open and close to both sides through a correspondingly configured window opener.

[0026] The window opener is arranged on the inner bottom plate of the driving vehicle and pushes and pulls the side telescopic plate through a flexible push rod.

[0027] The beneficial effects of the present invention are as follows:

[0028] (1) For this heavy-duty semi-finished cable storage and transfer device, through the setting of the driving vehicle and the turntable seat, the separation of traction and load-bearing can be achieved; during assembly, the driving vehicle runs to the bottom of the turntable seat, and the side telescopic plates extend to the left and right. Through the combination of the connecting columns of the driving vehicle and the connecting holes in the safety legs of the turntable seat, the driving vehicle is combined with the turntable seat and carries the turntable seat to complete the transfer task of the semi-finished product; during the transfer process of the semi-finished product, the semi-finished product does not touch the ground, and the turntable seat mainly bears the weight of the semi-finished product, while the driving vehicle mainly completes the traction, so that the traction and load-bearing are separated, effectively realizing flexible transfer work of the semi-finished product and effectively filling the market gap.

[0029] (2) The safety feet can achieve the conversion between the walking state and the supporting state. The control hook of the driving vehicle controls the lifting and lowering of the safety feet through the control window to meet the conversion of the working state. And when the turntable seat is separated from the driving vehicle, the telescopic safety feet will be lowered to the ground to provide sufficient friction for the turntable seat to avoid the side slip of the universal wheels of the turntable seat; in addition, during the running of the driving vehicle, if the pressure sensor senses an accident, it will directly perform an emergency brake and lower the telescopic safety feet to prevent the tilting of the semi-finished cable reel.

[0041] The present invention provides a heavy cable semi-finished product storage and transfer device, as Figures 1 to 10 shown.

[0042] The heavy cable semi-finished product storage and transfer device includes a separately arranged driving vehicle 1 and a disc base 2, and the driving vehicle 1 is located at the bottom of the disc base 2 and is detachably assembled with the disc base 1; the driving vehicle 1 includes a driving device, a detection system, a side telescopic plate 11 and a hollow connecting column 12 protruding from the side telescopic plate 11, and the side telescopic plates 11 are symmetrically arranged and can extend to both sides, and the detection system is arranged in the hollow connecting column 12; the disc base 2 includes a load-bearing beam, load-bearing universal wheels 24 rotatably arranged at the bottom of the load-bearing beam, a telescopic arm 23 and a safety leg 3, and a support groove 21 is formed on the load-bearing beam, and the telescopic arm 23 is connected between the symmetrically arranged load-bearing beams and the distance between them is adjustable.

[0043] The safety leg 3 includes a safety leg housing 31 fixed below the load-bearing beam and a telescopic safety foot installed in the safety leg housing 31, and the telescopic safety foot is arranged to move up and down in the safety leg housing 31 and can move upward to be in a walking state or move downward to be in a supporting state.

[0044] A control window 311 and a connection hole 312 corresponding to the connecting column 12 are also formed on the safety leg housing 31, and the driving vehicle 1 controls the connecting column 12 to be inserted into or separated from the connection hole 312 to assemble or separate from the disc base 2.

[0045] A control port 115 is formed on the side telescopic plate 11, and an up-and-down moving device is further provided inside it. An induction control device that moves synchronously with it is provided on the up-and-down moving device, and the induction control device is arranged horizontally. The induction control device includes a control hook 13 located outside the side telescopic plate 11 and a side pressure sensor 14 located inside the side telescopic plate, and the two are connected by a control tongue 15. In this embodiment, the up-and-down moving device adopts the meshing transmission of a rack 111 and a gear shaft 112, and the gear shaft 112 is installed inside the side telescopic plate 11 and rotates under the action of a motor 113. A sliding holding groove 114 is also fixedly provided inside the side telescopic plate 11. After meshing with the gear shaft 112, the rack 111 moves up and down in the sliding holding groove 114. The control tongue 15 passes through the rack 111 and drives the control hook 13 to move up and down synchronously with the rack 111 outside the side telescopic plate 11, and the control hook 13 is used to control the lifting of the telescopic safety foot.

[0046] The telescopic safety foot includes a safety foot seat 41, a spring frame 42 fixedly arranged on the safety foot seat 41, and a transmission rod frame 43 fixedly arranged on the spring frame 42. A transmission rod 44 is also rotatably connected to the top of the transmission rod frame 43, and a support block group is provided at the bottom of the transmission rod 44;

[0047] The support block group includes an outer support block 45 and an inner support block 46 that are symmetrically arranged at intervals. The two are fixedly connected by a connecting strip 48 located below them, and the inner support block 46 is rotatably connected to the bottom end of the transmission rod 44. The spring frame 42 is arranged side by side between the outer support block 45 and the inner support block 46, and a return spring 47 is also connected between the spring frame 42 and the inner support block 46. A chute 411 for sliding the built-in connecting strip is also formed on the safety foot seat 41, and the length of the connecting strip 48 is set to be equal to the width of the chute 411.

[0048] When the control hook of the driving vehicle pushes the transmission rod through the control window, the transmission rod drives the support block group to move outward and compress the return spring. After the support block group moves outward, a gap appears between the safety leg housing and the telescopic safety foot, and the safety foot seat is lifted upward and is in a walking state.

[0049] When the control hook of the driving vehicle disengages from the transmission rod and moves downward, the telescopic safety foot extends downward under the action of gravity. The return spring drives the support block group to move inward and return, and at the same time drives the transmission rod to move inward. After the support block group moves outward, the safety foot seat moves downward and is in a supporting state.

[0050] A lifting groove 441 and a safety groove 442 are further provided on the transmission rod 44 from top to bottom. The lifting groove is set as an inclined groove that inclines inward, and the safety groove is set as a rectangular groove and its depth is greater than the depth of the lifting groove.

[0051] Inside the side telescopic plate 11, there is also a U-shaped pressure sensing frame 116 fixed. The pressure sensing frame 116 is located between the rack 111 and the side pressure sensor 14, and auxiliary pressure sensors 117 for measuring vertical pressure are provided at both ends of the pressure sensing frame 116.

[0052] The detection system includes a camera device and a ranging sensor, and the detection system is connected to the driving device for control and extends out of both sides of the turntable 2 through the connection holes 312 on the safety legs 3 for information sensing.

[0053] The side telescopic plate 11 moves inwards and outwards to both sides through a correspondingly arranged window opener 118; in this embodiment, the window opener 118 is arranged on the inner bottom plate of the driving vehicle and pushes and pulls the side telescopic plate 11 through a flexible push rod 119.

[0054] More specifically, during operation, the semi-finished cable is placed in the support groove 21 of the turntable 2; after the driving vehicle runs to the bottom of the turntable, the side telescopic plate 11 extends to the left and right, so that the connection column of the driving vehicle is combined with the connection holes in the safety legs of the turntable 2; after the driving vehicle is combined with the turntable, it carries the turntable to complete the transfer task of the semi-finished product. During the transfer of the semi-finished product, the semi-finished product no longer touches the ground; among them, the turntable mainly bears the weight of the semi-finished product, and the driving vehicle mainly completes the traction.

[0055] Depth cameras are installed at the front and rear ends of the driving vehicle for visual navigation; laser single-point ranging sensors 16 are installed on both sides of the depth cameras for accurately sensing distance information and fusing the depth information of the depth cameras; a charging port is installed below the depth cameras; an observation camera is installed inside the depth cameras for observing the width of the turntable and the centering of the wire reel when the semi-finished product of the gantry is offline. The entire driving vehicle uses four steering wheels as driving wheels, and at the same time, the steering wheels can complete the steering control.

[0056] Side telescopic plates 11 are provided on both sides of the driving vehicle and can expand to both sides. Connection columns 12 are provided on the side telescopic plates to realize the docking with the connection holes of the safety legs of the turntable. Cameras and laser single-point ranging sensors are arranged inside the connection columns for sensing the environmental information on both sides of the vehicle during walking. Since the vehicle body is blocked after the driving vehicle is combined with the turntable, the cameras and laser single-point ranging sensors are extended out of both sides of the turntable through the connection holes on the safety legs to complete information sensing. A control hook is installed in the middle of the side telescopic plate for controlling the lifting, lowering and emergency safety braking of the safety legs.

[0057] The control circuit of the driving vehicle is installed in the controller compartment 18 to complete the basic walking control function; the video processing circuit is installed in the video processor compartment to implement the operation of all video detection-related algorithms; the control circuit board and the video processing circuit board communicate with each other through a serial port. Four steering wheels are installed at the four corners of the driving vehicle, and the control lines of each steering wheel are connected to the drivers in the four steering wheel driver compartments 19; the steering wheel drivers 19 communicate with the control circuit board through a CAN bus. A large-capacity and high-current lithium iron phosphate battery is placed in the middle of the driving vehicle. The control circuit reads the relevant information of the battery (including power, voltage, current, temperature, etc.) through a 485 bus. Two side telescopic plates are installed inside the vehicle through two inverted drawers (the bottom surface of the drawer faces upward), and can make opening and closing movements on both sides of the vehicle under the drive of the window opener. The bottom surface of the drawer is provided with battery slots and sliding slots to realize the installation and movement of relevant components. Two window openers are used to complete the telescopic drive of the side panels. The main body of the window opener is installed on the bottom plate inside the driving vehicle, and the end of the flexible push rod of the window opener is installed on the sliding frames 121 on both sides. The sliding frames 121 are fixed to the inner sides of the side telescopic plates 11, and the equipment installed on the inner sides of the side panels also includes pressure sensing frames 116. A laser single-point ranging sensor 16 is also installed beside the window opener to measure the telescopic distance of the side telescopic plates.

[0058] The installation of the side telescopic plate device of the driving vehicle is as Figure 4 shown. The flexible push rod is installed on the sliding frame; the sliding frame is sleeved on two guide rails welded to the inner side of the side telescopic plate through two linear bearings; hooks are left at one end of the two guide rails close to the vehicle body, which can prevent the sliding frame from detaching from the guide rails, so as to realize the pulling of the side telescopic plate by the flexible push rod. Two sensing inner columns 122 are installed above the sliding frame 121. A lateral camera and a laser single-point ranging sensor 16 are installed in each of the sensing inner columns 122. When the driving vehicle is not combined with the disc seat, the sensing inner columns 122 are used to sense the objects and personnel on both sides of the driving vehicle; after the driving vehicle is combined with the disc seat, the sensing inner columns 122 are used to sense the objects and personnel on both sides of the disc seat. During the outward pushing process of the window opener, it first pushes the sensing inner column out of the connecting column, and then pushes out the side telescopic plate. During the inward pulling process of the window opener, it first retracts the sensing inner column into the connecting column, and then pulls back the side panel.

[0059] Inside the inner side of the side telescopic plate, there is an up-and-down moving device composed of a stepper motor, a toothed shaft, bearings, and a rack. It can drive the rack to slide up and down inside the inner side of the side telescopic plate under the restriction of six sliding holding grooves. The rack is embedded with a control tongue, which extends out from the control port, and a control hook is installed at the end. Under the action of the rack, the control hook can move up and down on the outer side of the side telescopic plate. The control tongue penetrates the rack and the pressure sensing frame and directly acts on a pressure sensor to sense the external pressure received by the control hook. The pressure sensing frame extends to both sides inside the inner side of the side telescopic plate, and a top pressure sensor is installed at each end to sense the stability of the center of gravity of the semi-finished cable on the disc base and the operation of the load-bearing universal wheels of the disc base during the transfer of the trolley. Once there is a tendency of possible accident, the safety legs will be immediately controlled for emergency safety braking.

[0060] The disc base is mainly composed of a load-bearing beam, load-bearing universal wheels, telescopic arms, and safety legs. Among them, a groove is provided in the load-bearing beam for placing the wire reel of the semi-finished cable. The telescopic arms are provided to facilitate the disc base to be applicable to wire reels of different widths. The safety legs are directly fixed under the load-bearing beam, and the connecting column of the driving vehicle drives the disc base to move forward directly through the connecting holes in the safety legs.

[0061] The safety leg is composed of a safety leg housing and a telescopic safety foot. Limit plates are installed at both ends of the safety foot, so that the safety foot can be stably sleeved inside the safety leg housing and can move up and down inside the safety leg housing. There are connecting holes on the safety leg housing. The safety holes penetrate both sides of the safety leg and are welded by a cylinder in the middle. There is a control window in the middle of the inner side of the safety leg housing. The control hook of the driving vehicle controls the lifting and lowering of the safety foot through the control window. The telescopic safety foot has two states: the lifted state and the lowered state. During the process of the driving vehicle carrying the disc base to move, the telescopic safety foot is in the lifted state. In the following two cases, the telescopic safety foot will drop: First, when the disc base is separated from the driving vehicle, the telescopic safety foot will be lowered to the ground to give sufficient friction to the disc base to avoid the side slip of the universal wheels of the disc base; Second, during the driving process of the driving vehicle, if the pressure sensor senses an accident, it will directly perform an emergency brake and lower the telescopic safety foot to prevent the side tilt of the semi-finished cable wire reel.

[0062] A spring frame is welded on the telescopic safety foot; a transmission rod frame is welded on the spring frame, and the lower part of the transmission rod frame is connected to the transmission rod through a rotating shaft; the lower end of the transmission rod is connected to the inner support block through a connecting shaft and can drive the inner support block to move in the inner and outer directions; the lower part of the inner support block is welded to the support block connecting bar; the support block connecting bar is embedded in the connecting bar chute of the safety foot and is simultaneously welded to the outer support block. In the support state of the support block, the inner support block and the outer support block are stuck between the safety leg housing and the safety foot to play a supporting role.

[0063] After the control hook of the driving vehicle pushes the transmission rod through the control window on the safety leg, the transmission rod drives the inner support block and the outer support block to move outward, while compressing the spring installed between the spring bracket and the right support block. After the inner and outer support blocks move outward, a gap appears between the safety leg housing and the telescopic safety foot, providing space for the lifting of the safety foot.

[0064] The control hook on the driving vehicle is realized through the control window on the inner side of the safety leg housing. The specific movement is completed by the cooperation of the transmission rod, spring, support block, and support block connecting strip.

[0065] The control principle of the telescopic process of the safety leg is as follows:

[0066] The upper end of the transmission rod is connected to the transmission rod bracket through a rotating shaft; the lower end is connected to the support block through a connecting shaft. Without external force control, due to gravity, the built-in transmission rod extends downward, and the two support blocks move inward under the action of the return spring and directly get stuck between the safety leg housing and the telescopic safety foot to complete the safety support of the disc seat. The two support blocks are connected by a connecting strip. The connecting strip is embedded in the connecting strip chute in the safety foot and can slide along the inner and outer directions of the safety leg.

[0067] When the control hook on the driving vehicle acts on the lifting groove of the transmission rod through the control window, it pushes the transmission rod to move outward, thereby driving the two support blocks to slide outward and squeezing the spring. After the support block moves away from the support position, the control hook of the driving vehicle can lift the telescopic safety foot. At this time, the control hook is in the slit above the control window, which can fix the width of the entire disc seat to prevent the connecting column from being displaced; at the same time, the two actions of pushing and pulling the safety leg can be realized.

[0068] When the driving vehicle senses abnormal pressure, it quickly moves the control hook downward to the safety groove of the transmission rod. The safety foot seat extends downward under the action of gravity. At the same time, since the transmission rod loses the extrusion force, the return spring drives the support block inward to realize the emergency clamping of the safety leg seat.

[0069] The above shows and describes the basic principle, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
