Description

Technical Field

[0001] The invention relates to the technical field of cranes, and in particular to an intelligent crane with an anti-unhooking device. Background Art

[0002] An intelligent crane refers to a device that integrates sensors, intelligent decision-making software and crane systems. It can automatically sense, analyze, reason, make decisions and control the objects being hoisted. This type of crane can automatically perform operations such as identification, inspection, picking and placing, path planning, swing compensation, etc., and can record and monitor the working status of its own equipment during automatic operation, automatically diagnose faults and issue alarms.

[0003] In the prior art, when an intelligent crane is lifting cargo, a hook on the crane is hung on the cargo, and then a baffle on the hook is driven by a motor to rotate, and the baffle blocks the hook. The crane pulls the hook through a steel wire rope, so that in the process of pulling the cargo, the baffle and the hook cooperate to prevent unhooking.

[0004] However, the anti-unhooking hook can only lift one cargo at a time. When the intelligent crane uses multiple anti-unhooking hooks to lift multiple cargoes, the anti-unhooking hook will shake when moving with the wire rope. The shaking will cause the anti-unhooking hook to get tangled with the wire rope, which is not conducive to the working efficiency of the intelligent crane. Summary of the invention

[0005] The object of the present invention is to provide an intelligent crane with an anti-unhooking device to solve the technical problem that the anti-unhooking hook in the prior art can only lift one cargo at a time. When the intelligent crane uses multiple anti-unhooking hooks to lift multiple cargoes, the anti-unhooking hooks will shake when moving with the wire rope. The shaking will cause the anti-unhooking hook to get tangled with the wire rope, which is not conducive to the working efficiency of the intelligent crane.

[0016] As a further solution of the present invention: the edges on both sides of the outlet are respectively provided with rounded corners, and the rounded corners cooperate with the steel wire rope.

[0017] As a further solution of the present invention: positioning columns are fixedly connected on both sides of the bottom end of the connecting tube, positioning holes are respectively opened on both sides of the top of the fixing seat, a spring is provided between the positioning column and the fixing seat, the upper and lower ends of the spring are respectively fixedly connected to the positioning column and the inner wall of the positioning hole, and the inner wall of the positioning hole is slidably connected to the positioning column.

[0018] Beneficial effects of the present invention:

[0019] 1. Several fixed tubes are provided on both sides of the bottom of the base. Two fixed tubes can be provided on both sides of one end of the base, so that the fixed tubes at both ends of the base can be symmetrically arranged. When the fixed tube moves along the bottom of the base, the fixed tube moves with the connecting tube. When the fixed tube and the connecting tube move along the bottom of the base, the steel wire ropes in the fixed tube and the connecting tube move synchronously. The steel wire rope passes through the fixed seat to lift the goods. The steel wire rope can move with the goods through the fixed seat. The goods at both ends of the bottom of the base are abutted together by movement, thereby ensuring that multiple goods are abutted to avoid shaking. Among them, the steel wire rope is arranged in the fixed tube and the connecting tube, and the inner walls of the fixed tube and the connecting tube abut the steel wire rope. The limit line is arranged to avoid the shaking of the wire rope, and at the same time, the knotting of multiple wire ropes during movement is avoided. When the intelligent crane pulls the wire rope upward, the wire rope moves upward with the wire rope through the collecting seat, and the wire rope can lift the cargo by pulling the fixed seat. When the fixed seat and the bottom end of the connecting tube are abutted, the wire rope continues to move upward, and the fixed seat abuts the connecting tube to slide along the inner wall of the fixed tube. When the connecting tube is fully extended into the fixed tube, the fixed seat abuts the bottom end of the fixed tube. At this time, when the fixed seat lifts the cargo and continues to move upward through the wire rope, the fixed seat abuts against the fixed tube to drive the base to move upward, thereby achieving the effect that the base and the cargo are lifted by the intelligent crane.

[0020] 2. When the fixed seat is installed on the goods, the hook at the bottom of the fixed seat needs to be hung on the goods. At this time, the fixed seat and the bottom end of the connecting pipe do not butt against each other. The fixed seat rotates with the hook and then the hook is hung on the goods. A motor is arranged in the fixed seat. The motor drives the baffle to rotate. Both ends of the baffle rotate along the inner wall of the rotating groove. When the baffle and the bottom end of the hook butt against each other, the baffle blocks the hook from hanging on the goods, thereby achieving the effect of preventing the hook from unhooking the goods.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 8 As shown, an intelligent crane with an anti-unhooking device comprises: a base 1, a fixing seat 5 and a hook 6.

[0033] A plurality of fixed tubes 3 are respectively connected at both ends of the base 1, and a connecting tube 4 is slidably connected to the inner wall of the fixed tube 3. A plurality of fixed tubes 3 are provided on both sides of the bottom of the base 1. Two fixed tubes 3 can be provided on both sides of one end of the base 1, so that the fixed tubes 3 at both ends of the base 1 can be symmetrically arranged. When the fixed tube 3 moves along the bottom of the base 1, the fixed tube 3 moves with the connecting tube 4.

[0034] The fixing seat 5 is provided with several groups and is connected with the connecting pipe 4. The top of the fixing seat 5 is fixedly connected with a steel wire rope 8, and the steel wire rope 8 is arranged in the fixing pipe 3 and the connecting pipe 4. The top of the steel wire rope 8 is fixedly connected with a collecting seat 9, and the top of the collecting seat 9 is fixedly connected with a steel rope 10. When the fixing pipe 3 and the connecting pipe 4 move along the bottom of the base 1, the steel wire rope 8 in the fixing pipe 3 and the connecting pipe 4 moves synchronously, and the steel wire rope 8 is passed through the fixing seat 5 to lift the goods. The steel wire rope 8 can move with the goods through the fixing seat 5. The goods at both ends of the bottom of the base 1 are abutted together by movement, so as to ensure that the multiple goods are abutted to avoid shaking. Among them, the steel wire rope 8 is arranged in the fixing pipe 3 and the connecting pipe 4, and the inner walls of the fixing pipe 3 and the connecting pipe 4 abut the steel wire rope 8 When the intelligent crane pulls the steel rope 10 upward, the steel rope 10 moves upward with the steel rope 8 through the collecting seat 9, and the steel rope 8 can lift the goods by pulling the fixing seat 5. When the fixing seat 5 and the bottom end of the connecting pipe 4 are against each other, the steel rope 8 continues to move upward, and the fixing seat 5 pushes the connecting pipe 4 to slide along the inner wall of the fixing pipe 3. When the connecting pipe 4 is fully extended into the fixing pipe 3, the fixing seat 5 and the bottom end of the fixing pipe 3 are against each other. At this time, when the fixing seat 5 lifts the goods and continues to move upward through the steel rope 8, the fixing seat 5 pushes the fixing pipe 3 to drive the base 1 to move upward, thereby achieving the effect that the base 1 and the goods are lifted by the intelligent crane.

[0035] The hook 6 is fixedly connected to the bottom end of the fixing seat 5, and a rotating groove 16 is opened on the top of the hook 6. The inner wall of the rotating groove 16 is rotatably connected with a baffle 7. The top of the baffle 7 is cooperatively connected with the fixing seat 5. When the fixing seat 5 installs the goods, the hook 6 at the bottom end of the fixing seat 5 needs to be hung on the goods. At this time, the fixing seat 5 and the bottom end of the connecting pipe 4 do not abut each other. The fixing seat 5 rotates with the hook 6 and then the hook 6 is hung on the goods. A motor is arranged in the fixing seat 5, and the motor drives the baffle 7 to rotate. The two ends of the baffle 7 rotate along the inner wall of the rotating groove 16. When the baffle 7 and the bottom end of the hook 6 abut against each other, the baffle 7 blocks the hook 6 from being hung on the goods, thereby realizing the effect of preventing the hook 6 from unhooking the goods.

[0036] In some specific implementation schemes, the steel wire ropes 8 are provided in several groups and are respectively matched with the fixed pipes 3. The several steel wire ropes 8 are respectively arranged around the collecting seat 9. When the intelligent crane pulls the steel rope 10 vertically upward, the steel rope 10 pulls the collecting seat 9, and the collecting seat 9 is located at the position where the center line of multiple steel wire ropes 8 is collected, thereby ensuring that when the collecting seat 9 pulls multiple steel wire ropes 8, each steel wire rope 8 is subjected to uniform force.

[0037] In some specific implementation schemes, a plurality of slide grooves 13 are longitudinally provided at both ends of the base 1, and connecting grooves 20 are respectively provided on both sides of the base 1. Rollers 11 are respectively connected to both sides of the base 1, and the rollers 11 cooperate with the steel wire rope 8. The slide grooves 13 and the connecting grooves 20 are communicated with each other. A slide seat 14 is connected to the slide groove 13 and is slidably connected to the slide seat 14. The slide seat 14 is fixedly connected to the top of the fixed pipe 3. The slide seat 14 is connected to the driving component. Before the intelligent crane pulls the steel rope 10 vertically upward, the driving component drives the slide seat 14 to slide along the inner wall of the slide groove 13, and the slide seat 14 drives the fixed pipe 3 and the connecting pipe 4 to move, thereby driving the goods in. When the steel wire rope 8 moves upward, the steel wire rope 8 moves along the roller 11, and the roller 11 can roll, and the roller 11 and the steel wire rope 8 are in contact with each other. On the one hand, the roller 11 provides support for the movement of the steel wire rope 8, avoids direct contact between the steel wire rope 8 and the base 1 to generate friction, and reduces the friction force of the steel wire rope 8. On the other hand, the roller 11 limits the steel wire rope 8 to avoid vibration when the steel wire rope 8 moves vertically upward.

[0038] In some specific embodiments, the driving assembly includes: a servo motor 2 and a screw 12, the servo motor 2 is fixedly connected to the side end of the base 1, the servo motor 2 is fixedly connected to the screw 12, a threaded hole 15 is axially opened on the slide 14, the screw 12 is threadedly connected to the threaded hole 15, and the side end of the screw 12 is rotatably connected to the inner wall of the slide groove 13. When the driving assembly is running, the servo motor 2 runs, the servo motor 2 drives the screw 12 to rotate, and the screw 12 drives the slide 14 to move by being threadedly connected to the threaded hole 15. When the screw 12 stops rotating, the screw 12 provides a threaded fixation for the slide 14 by being threadedly connected to the threaded hole 15.

[0039] In some specific embodiments, a connecting plate 21 is provided between the slide 14 and the roller 11, and the two ends of the connecting plate 21 are fixedly connected to the slide 14 and the roller 11 respectively, and the connecting plate 21 is slidably connected to the inner wall of the connecting groove 20. When the slide 14 moves, the slide 14 drives the roller 11 to move through the connecting plate 21, and the roller 11 moves with the wire rope 8 following the cargo. When the inner wall of the connecting groove 20 and the connecting plate 21 are in contact with each other, the base 1 further provides support for the slide 14 and the roller 11.

[0040] In some specific implementation schemes, limiting grooves 25 are respectively provided on both sides of the inner wall of the fixed tube 3, an outlet 23 is provided at the side end of the fixed tube 3, and the two ends of the connecting tube 4 are respectively fixedly connected to the limiting plates 22, the limiting plates 22 are slidably connected to the inner walls of the limiting grooves 25, and the wire rope 8 cooperates with the outlet 23. When the connecting tube 4 slides along the inner wall of the fixed tube 3, the limiting plates 22 fixed at both ends of the connecting tube 4 slide along the inner wall of the limiting grooves 25, and the fixed tube 3 provides a limiting effect for the connecting tube 4 through the limiting plates 22 and the inner walls of the limiting grooves 25 to prevent the connecting tube 4 from rotating. It should be noted that the top of the connecting tube 4 is always in the fixed tube 3. When the wire rope 8 moves upward, the wire rope 8 passes through the outlet 23 and moves along the roller 11.

[0041] In some specific embodiments, rounded corners 24 are respectively provided on the edges on both sides of the outlet 23, and the rounded corners 24 cooperate with the steel wire rope 8. When the steel wire rope 8 passes through the outlet 23 and moves along the inner wall of the outlet 23, in order to avoid the edge of the outlet 23 causing wear to the steel wire rope 8, the rounded corners 24 provided on the outlet 23 reduce the damage to the steel wire rope 8 caused by the edge of the outlet 23.

[0042] In some specific implementation schemes, positioning columns 19 are fixedly connected to both sides of the bottom end of the connecting tube 4, positioning holes 17 are respectively opened on both sides of the top of the fixing seat 5, and a spring 18 is provided between the positioning column 19 and the fixing seat 5. The upper and lower ends of the spring 18 are fixedly connected to the positioning column 19 and the inner wall of the positioning hole 17 respectively, and the inner wall of the positioning hole 17 is slidably connected to the positioning column 19. When the hook 6 is hung on the cargo, the wire rope 8 is in a relaxed state. At this time, the fixing seat 5 and the connecting tube 4 are not abutted together. When the fixing seat 5 rotates with the hook 6 and then hangs the hook 6 on the cargo, the spring 18 moves with the fixing seat 5. The spring 18 is When the steel wire rope 8 moves upward with the steel wire rope 8, the staff controls the direction of the fixing seat 5 and aligns the positioning hole 17 with the positioning column 19. At this time, the fixing seat 5 shrinks with the spring 18. When the positioning column 19 is inserted into the positioning hole 17, the fixing seat 5 and the connecting pipe 4 are abutted. At this time, the spring 18 is in an elastically stretched state. The spring 18 provides elastic tension to pull the positioning column 19. The limiting effect provided by the connecting pipe 4 is transmitted to the fixing seat 5 through the positioning column 19 and the inner wall of the positioning hole 17, thereby ensuring that the fixing seat 5 will not rotate and deviate when the goods are lifted.

[0043] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
