Description

Technical Field

[0001] The present invention relates to the technical field of hanging brackets, and specifically to a novel coil steel pallet seat lifting tool. Background Art

[0002] The 21st century is an era of globalization and also an era of technology. With the rapid development of social productive forces and the increasing demand for material life, the goods loaded at port terminals are in an endless stream every day. Compared with the previous manual handling mode, the current handling mode is mostly mechanical. Forklifts can be used to handle some relatively light goods. However, for a material with a large weight and volume, such as coil steel, which is a rigid material with a large volume and a heavy weight and cannot be placed on a forklift, and the forklift cannot bear the weight of the coil steel. At this time, a special lifting tool for coil steel is needed to transfer its position. A lifting tool is a machine specifically for handling heavy materials and is widely used in the construction and logistics industries for material transportation due to its good load-bearing capacity and little influence by terrain.

[0003] A coil steel lifting tool with an internal balancer, with the publication number CN113003396A, includes a C-shaped lifting tool assembly. The C-shaped lifting tool assembly includes a lower bracket of the lifting tool, a vertical connecting frame of the lifting tool, and an upper lifting frame of the lifting tool. The front and rear of the upper lifting frame of the lifting tool are fixedly connected with screw hole plates. One side of the upper lifting frame of the lifting tool is fixedly connected with a gear mounting plate. A center hole of the lifting frame is opened in the middle of the upper lifting frame of the lifting tool, and sliding sleeve mounting holes are opened at both ends of the center hole of the lifting frame. Through the cooperative setting of the C-shaped lifting tool assembly, a lifting core shaft, a transmission gear, and a balance adjustment motor, the coil steel lifting tool with an internal balancer has the effect of being able to adjust the position of the lifting force application point to maintain balance and prevent the coil steel from slipping. Through the cooperative setting of the C-shaped lifting tool assembly, a transmission screw, a downward pressure motor, and a pressing plate, the coil steel lifting tool with an internal balancer has the effect of being provided with a clamp for fixing the coil steel to further fix the coil steel and prevent it from slipping. For the coil steel lifting tool with an internal balancer, through the cooperative setting of the C-shaped lifting tool assembly, a lifting core shaft, a transmission gear, and a balance adjustment motor, the coil steel lifting tool with an internal balancer has the effect of being able to adjust the position of the lifting force application point to maintain balance and prevent the coil steel from slipping. The lifting core shaft slides above the C-shaped lifting tool assembly through the cooperation of the transmission gear and the balance adjustment motor. The lifting rope of the coil steel lifting tool is tied to one end of the lifting core shaft. Changing the position of the lifting core shaft can change the position of the lifting force application point relative to the center of gravity of the coil steel, thereby realizing the adjustment of the position of the lifting force application point to maintain balance and prevent the coil steel from slipping.

[0004] The comparison device is fixedly connected with screw hole plates in front of and behind the lifting frame on the sling, and is fixed by threaded connection. This connection method is a relatively traditional connection method, and most slings on the market adopt this method. This connection method is relatively convenient to disassemble. However, after long-term use, the threaded connection at the screw hole will wear, resulting in loose connection and possible falling of goods, which has a certain degree of danger. Moreover, this connection method cannot bear overly heavy materials. The huge gravity may directly cause the threaded connection to fall off, resulting in the falling of the materials inside the sling, which is very dangerous. In addition, the stability of the comparison device is poor. When the coil steel moves upward, it may collide with the surrounding walls or obstacles and shake. Without a stable structure for the coil steel at the upper end, the coil steel will follow and shake. The shaking force will increase the gravity borne by the sling, and may cause the sling wire rope to break due to being unable to bear the corresponding weight.

[0005] A wire sling with the publication number of CN211141272U is provided on a rotating drum. The sling includes a central shaft, an upper sling plate, a lower sling plate and a linkage rod. The upper sling plate and the lower sling plate are respectively sleeved on the upper end and the lower end of the central shaft. A clamping plate one is connected to the outside of the upper sling plate through an upper sling arm, and a clamping plate two is connected to the outside of the lower sling plate through a lower sling arm. A pin shaft one is passed through between the clamping plates one. A pin shaft two is passed through between the clamping plates two. The upper part of the linkage rod is sleeved on the pin shaft one, and the lower part is sleeved on the pin shaft two. A pin shaft three is arranged on one of the upper sling arms of the upper sling plate, and a pin shaft four is arranged on one of the lower sling arms of the lower sling plate. An operating rod and a connecting rod one are respectively rotatably connected to the pin shaft three, and a connecting rod two is rotatably connected to the pin shaft four. The connecting rod one and the connecting rod two are connected through a pin shaft five. Compared with the prior art, the wire sling of the present invention can easily take out the wire coil from the rotating drum and improve the blanking efficiency.

[0006] The comparison device uses a wire rope as the traction structure, but there is no anti-wear structure for the wire rope. The wire rope of the sling is a consumable, and it needs to be replaced after a certain period of use. When handling goods such as coil steel, it will rub against the wire rope. Long-term rubbing will cause wear on the outside of the wire rope and make it unusable, thus affecting the service life of the wire rope and requiring early replacement of the wire rope, increasing the operating cost of the enterprise.

[0007] In view of the above problems, it is urgent to innovate and design on the basis of the original sling structure. Summary of the Invention

[0008] The purpose of the present invention is to provide a new type of coil steel pallet seat sling to solve the problems of insufficient bearing capacity at the threaded connection when using the sling, insufficient stability of the coil steel when the sling is impacted, and no protective structure for the wire rope mentioned in the above background technology.

[0009] To achieve the above object, the present invention provides the following technical solution: a novel lifting device for a coil steel pallet seat, comprising a connecting block, a traction pull ring, a steel wire rope, a limiting frame, a first chute and a counterweight. The upper end of the connecting block is fixedly installed with a traction pull ring, and the lower end of the connecting block is fixedly connected with a steel wire rope. The steel wire rope passes through the inside of the first chute, and the first chute is opened inside the limiting frame, and a counterweight is fixedly installed at the lower end of the limiting frame;

[0010] The lower end of the steel wire rope is fixedly connected with a second connector, and the second connector is nested at the upper end of the chain assembly. The chain assembly passes through the inside of the second chute, and the second chute is opened inside the pallet base. Support legs are fixedly installed at the lower end of the pallet base, and a coil steel is arranged at the upper end of the pallet base. The tail end of the chain assembly is nested with a first connector, and a slot hole is opened inside the first connector. A connecting rod is nested inside the slot hole, and a hook is fixedly installed at the tail end of the connecting rod. A rotating shaft is installed inside the hook, and a torsion spring is fixedly installed outside the hook. The upper end of the torsion spring is fixedly connected to the outside of the rotating shaft, and a locking rod is nested outside the rotating shaft, and the locking rod is installed inside the hook;

[0011] The steel wire rope is nested inside the sliding track, and the sliding track is fixedly installed outside the protective sheet, and a magnet is fixedly installed on the outside. A first limiting block is fixedly installed on the outside of the steel wire rope, and the first limiting block is fixedly installed at the upper end of the sliding track. A second limiting block is fixedly installed on the outside of the steel wire rope, and is fixedly installed at the lower end of the sliding track.

[0012] Preferably, the front view of the traction pull ring is semi-circular, and the connecting block and the limiting frame at the lower end of the traction pull ring are distributed vertically corresponding to each other; the traction pull ring and the limiting frame are distributed vertically corresponding to each other. When the traction pull ring is pulled, the steel wire rope will slide upward along the first chute, and the limiting frame will move downward by its own weight to squeeze the lower end of the steel wire rope.

[0013] Preferably, the steel wire rope and the limiting frame form a sliding structure through the first chute, and four groups of first chutes are opened around the midpoint of the limiting frame; four groups of first chutes are provided, so that four steel wire ropes can slide upward along the first chute.

[0014] Preferably, two groups of counterweights are symmetrically arranged about the midpoint of the limiting frame, and the counterweights and the first chute are distributed in a dislocation manner with respect to the bottom end of the limiting frame; the counterweights and the first chute are distributed in a dislocation manner to avoid interfering with the sliding of the steel wire rope inside the first chute. The counterweights are symmetrically distributed about the midpoint of the limiting frame, which can make both ends of the limiting frame in a balanced state, and the weight of the counterweights will cause the limiting frame to slide downward along the steel wire rope through the first chute.

[0015] Preferably, the second connector and the chain assembly form a rotating structure, and the chain assembly forms a sliding structure with the tray base through the second chute; the second connector and the chain assembly form a rotating structure, which can adjust the orientation of the lower chain assembly, facilitating the installation of the chain assembly. The chain assembly slides inside the tray base through the second chute, enabling the chain assembly to penetrate the inside of the tray base and fix the tray base.

[0016] Preferably, the connecting rod forms a rotating structure with the first connector through the slot hole, and the hook at the upper end of the connecting rod forms an engaging structure with the chain assembly; the connecting rod forms a rotating structure with the first connector through the slot hole, which can adjust the orientation of the hook fixedly installed at the upper end of the connecting rod, facilitating the installation of the hook and the first end of the chain assembly. Installing the hook and the first end of the chain assembly can fix the lower tray base.

[0017] Preferably, the locking rod forms a rotating structure with the hook through the rotating shaft, and the rotating shaft forms an elastic structure with the hook through the torsion spring; the locking rod forms a rotating structure with the hook through the rotating shaft, which can facilitate the installation and fixation of the locking rod with the first end of the chain assembly. The torsion spring can automatically reset the locking rod through its own elastic force when not subjected to extrusion force, preventing the first end of the chain assembly from falling off the inside of the hook, thus causing the lower tray base to lose fixation and fall from the lower end of the hanger.

[0018] Preferably, the material of the protective sheet is cold-rolled steel, and the thickness of the protective sheet is 0.2 - 0.4 MM; cold-rolled steel has good toughness and can be bent. The thickness of the protective sheet being 0.2 - 0.4 MM allows the cold-rolled steel to be bent to a certain extent without being easily pierced and damaged.

[0019] Preferably, the protective sheet forms a sliding structure with the steel wire rope through the sliding track, and there are four groups of protective sheets symmetrically distributed about the midpoint of the coiled steel. Moreover, there are two groups of the first limiting block and the second limiting block symmetrically arranged above and below the midpoint of the sliding track; the protective sheet forms a sliding structure with the steel wire rope through the sliding track, which can enable the protective sheet to better protect the steel wire rope, preventing the steel wire rope from rubbing against the coiled steel and causing wear to the steel wire rope, affecting its service life. The first limiting block and the second limiting block are installed on the steel wire rope and distributed at both ends of the sliding track to prevent the sliding track from driving the protective sheet to move randomly on the steel wire rope and affecting the operation of other structures of the hanger. The four groups of protective sheets can correspondingly protect the four groups of steel wire ropes, preventing damage to a certain steel wire rope and thus causing potential safety hazards.

[0020] Preferably, the magnet and the coiled steel form a magnetically attractive structure; the magnet can generate a magnetic attraction reaction with the coiled steel through its own magnetism, causing the protective sheet to fit on the outside of the coiled steel without random sliding.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This new type of coil steel pallet seat lifting tool:

[0022] 1. There is a structure for increasing the stability of the hanging bracket. A limit bracket is provided at the upper end of the steel wire rope. When the hanging bracket transports the coil steel, the limit bracket slides downward along the upper end of the steel wire rope under the action of the lower gravity block, making the steel wire rope fully fit on the outside of the coil steel, preventing the coil steel from shaking due to impact, and thus increasing the load-bearing capacity of the hanging bracket.

[0023] 2. There is a base connection structure with good load-bearing capacity. A chain assembly is connected to the lower end of the steel wire rope, and a hook is installed at the end of the chain assembly. The chain assembly is passed through the inside of the pallet base, and the end hook of the chain assembly is connected to the head end of the chain assembly, so that the pallet base is connected to the upper steel wire rope. By setting four groups of connection structures and fixing them at the main points of the pallet base, the overall load-bearing capacity of the hanging bracket is improved.

[0024] 3. There is a structure for preventing the wear of the steel wire rope. By setting corresponding protective sheets between the steel wire rope and the coil steel, it is prevented that the steel wire rope rubs against the outside of the coil steel, causing the steel wire rope to wear and reducing the service life of the steel wire rope. Moreover, the protective sheet can be adjusted in position on the outside of the steel wire rope through a sliding track to protect the steel wire rope in all directions.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-9 , the present invention provides a technical solution: a novel coiled steel tray seat lifting tool, including a connecting block 1, a traction pull ring 2, a steel wire rope 3, a limiting frame 4, a first chute 5, a counterweight 6, a chain assembly 7, a second chute 8, a tray base 9, a first connector 10, a slot hole 11, a connecting rod 12, a hook 13, a rotating shaft 14, a torsion spring 15, a locking rod 16, a second connector 17, a support leg 18, a coiled steel 19, a protective sheet 20, a first limiting block 21, a second limiting block 22, a sliding track 23 and a magnet 24.

[0037] A traction pull ring 2 is fixedly installed at the upper end of the connecting block 1, and a steel wire rope 3 is fixedly connected to the lower end of the connecting block 1. The steel wire rope 3 penetrates through the inside of the first chute 5, and the first chute 5 is opened inside the limiting frame 4, and a counterweight 6 is fixedly installed at the lower end of the limiting frame 4;

[0038] According to Figures 1-3 shown, the front view of the traction pull ring 2 is semicircular, and the connecting block 1 at the lower end of the traction pull ring 2 and the limiting frame 4 are distributed vertically corresponding to each other; the steel wire rope 3 and the limiting frame 4 form a sliding structure through the first chute 5, and four groups of first chutes 5 are opened about the midpoint of the limiting frame 4; two groups of counterweights 6 are symmetrically arranged about the midpoint of the limiting frame 4, and the counterweights 6 and the first chute 5 are distributed in a staggered manner about the bottom end of the limiting frame 4;

[0039] After the wire rope 3 of this structure is fixed to the upper end of the tray base 9 through the chain assembly 7, the limit frame 4 slides downward along the upper end of the wire rope 3 due to its own gravity and the gravity of the counterweight 6. Since the wire rope 3 is obliquely connected and wider at the top and narrower at the bottom, it will tighten the wire rope 3 when sliding downward, and the wire rope 3 is in a taut state, closely fitting with the coil steel 19 inside. When the tray base 9 moves upward and hits an obstacle or shakes, the coil steel 19 at the upper end of the tray base 9 will always be fixed to the tray base 9 through the limit of the wire rope 3, preventing the coil steel 19 from shaking and becoming scattered, and shaking at the upper end of the tray base 9 will increase the gravity on the hanger.

[0040] The lower end of the wire rope 3 is fixedly connected with a second connector 17, and the second connector 17 is nested at the upper end of the chain assembly 7. The chain assembly 7 passes through the inside of the second chute 8, and the second chute 8 is opened inside the tray base 9. The lower end of the tray base 9 is fixedly installed with a support leg 18, and the upper end of the tray base 9 is provided with a coil steel 19. The tail end of the chain assembly 7 is nested with a first connector 10, and a slot hole 11 is opened inside the first connector 10. A connecting rod 12 is nested inside the slot hole 11, and a hook 13 is fixedly installed at the tail end of the connecting rod 12. A rotating shaft 14 is installed inside the hook 13, and a torsion spring 15 is fixedly installed outside the hook 13. The upper end of the torsion spring 15 is fixedly connected to the outside of the rotating shaft 14, and a locking rod 16 is nested outside the rotating shaft 14, and the locking rod 16 is installed inside the hook 13;

[0041] According to Figure 1 、 Figures 4-8 As shown in, the second connector 17 and the chain assembly 7 form a rotating structure, and the chain assembly 7 and the tray base 9 form a sliding structure through the second chute 8; the connecting rod 12 and the first connector 10 form a rotating structure through the slot hole 11, and the hook 13 at the upper end of the connecting rod 12 and the chain assembly 7 form a clamping structure; the locking rod 16 and the hook 13 form a rotating structure through the rotating shaft 14, and the rotating shaft 14 and the hook 13 form an elastic structure through the torsion spring 15;

[0042] In this structure, a first chute 5 is opened inside the tray base 9. The tail end of the wire rope 3 is fixed to the upper end of the chain assembly 7 through the second connector 17, and the chain assembly 7 passes through the inside of the tray base 9. Press the locking rod 16 inside the hook 13, the locking rod 16 squeezes the torsion spring 15 and rotates along the rotating shaft 14, and the hook 13 is clamped to the head end of the chain assembly 7. Release the locking rod 16, and through the elasticity of the torsion spring 15, the locking rod 16 is reset to prevent the hook 13 from falling off the head end of the chain assembly 7. By installing four groups of chain assemblies 7 at the main points of the tray base 9, its bearing capacity is increased and the tray base 9 is prevented from falling off the chain assembly 7.

[0043] The steel wire rope 3 is nested inside the sliding track 23, and the sliding track 23 is fixedly installed on the outside of the protective sheet 20. A magnet 24 is fixedly installed on the outside. A first limit block 21 is fixedly installed on the outside of the steel wire rope 3, and the first limit block 21 is fixedly installed at the upper end of the sliding track 23. A second limit block 22 is fixedly installed on the outside of the steel wire rope 3, and is fixedly installed at the lower end of the sliding track 23;

[0044] According to Figures 1-2 , Figure 9 As shown, the material of the protective sheet 20 is cold-rolled steel, and the thickness of the protective sheet 20 is 0.2 - 0.4 MM; the protective sheet 20 and the steel wire rope 3 form a sliding structure through the sliding track 23, and there are four groups of protective sheets 20 symmetrically distributed about the midpoint of the coil steel 19. And there are two groups of the first limit block 21 and the second limit block 22 symmetrically arranged up and down about the midpoint of the sliding track 23; the magnet 24 and the coil steel 19 form a magnetically attracting structure;

[0045] In this structure, the sliding track 23 is fixedly installed on the outside of the protective sheet 20, so that the outside of the steel wire rope 3 is nested inside the sliding track 23 for sliding. The first limit block 21 and the second limit block 22 are installed on the steel wire rope 3 at the upper and lower ends of the sliding track 23 to limit its sliding trajectory. Through the traction force of the upper traction pull ring 2, the steel wire rope 3 is driven to squeeze the protective sheet 20 to fit on the outside of the coil steel 19. The magnet 24 fixedly installed on the outside of the protective sheet 20 makes the protective sheet 20 and the coil steel 19 fit tightly together by magnetic force, preventing sliding after fitting. Through the barrier of the protective sheet 20, it is avoided that the steel wire rope 3 and the outside of the coil steel 19 rub against each other, causing wear of the steel wire rope 3 and reducing the service life of the steel wire rope 3.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
