Description

Technical Field

[0001] The present invention relates to the field of construction equipment, and in particular to a steel handling and hoisting equipment with an anti-dropping function. Background Art

[0002] As an important metal material, steel is widely used in many fields such as construction, bridges, machinery manufacturing, shipbuilding, and automobile manufacturing. With the rapid development of these industries, the demand for steel is increasing continuously. Traditional steel hoisting methods often use simple hooks or slings for operation. However, with the increase in the amount of steel used, it may be difficult for hooks or slings to stably grip the steel due to the shape, size, or weight of the steel, resulting in easy shaking or even dropping of the steel during handling or hoisting, posing a safety hazard.

[0003] For example, in the published patent No. CN202222449078.4, a handling and hoisting frame has the following deficiencies: This device fixes the steel by bundling it on the surface of the hook, and the electric hoist tightens the rope driven by the rotation of the motor end, and finally hoists and transports the steel on the surface of the hook. However, the overall volume and weight of the steel are large, and only the bundling method with ropes results in a low fixing coefficient, and the hoisting method of the hook is prone to steel shaking during movement, resulting in the steel slipping out and easily triggering safety accidents. Summary of the Invention

[0004] In order to improve the problem that the existing conventional steel handling and hoisting equipment has a low fixing coefficient for steel and is prone to steel dropping during handling, resulting in safety accidents, the present invention provides a steel handling and hoisting equipment with an anti-dropping function.

[0005] The steel handling and hoisting equipment with an anti-dropping function provided by the present invention adopts the following technical solutions: A steel handling and hoisting equipment with an anti-dropping function includes a moving frame. A rope mechanism for winding and lifting is arranged at the top of the moving frame. A first moving mechanism is connected to the rope end of the rope mechanism. A second moving mechanism is arranged at the moving end of the bottom of the first moving mechanism. A plurality of fixing mechanisms for fixing the steel are arranged at the moving end of the bottom of the second moving mechanism. A lateral tightening mechanism for assisting in preventing the steel from loosening is arranged on one side of each of the plurality of fixing mechanisms; Bottom plates are arranged at the bottoms of the plurality of fixing mechanisms. Moving grooves are formed on the surface of the bottom plates at the positions of the plurality of fixing mechanisms, and the moving grooves are movably inserted into the plurality of fixing mechanisms. Limiting rods for limiting are fixedly arranged at the positions of the fixing mechanisms in the moving grooves, and the limiting rods penetrate and are connected to the bottoms of the fixing mechanisms.

[0006] By adopting the above technical solution, the movement of the mobile end in the second moving mechanism drives multiple fixing mechanisms to perform clamping movements, thereby tightening and fixing the steel in the fixing mechanism. At the same time, when the fixing mechanism performs clamping movements, it drives the lateral tightening mechanism to protrude from the inside of the fixing mechanism, thereby making a secondary abutment on the surface of the steel, thus forming a multi-directional fixation of the steel. While improving the fixing effect, it avoids safety accidents caused by the falling off of the steel during transportation. At the same time, as the steel is horizontally fixed in multiple fixing mechanisms and cooperates with the second moving mechanism and the bottom plate at the upper and lower ends, an overall cage shape is formed for storing large-volume steel, increasing the scope of application.

[0007] Preferably, the second moving mechanism includes an installation housing fixedly arranged at the mobile end of the bottom of the first moving mechanism. The bottom of the installation housing is grooved, and a rotating rod is rotatably arranged in the groove. A plurality of threaded surfaces are arranged on the surface of the rotating rod. A first motor is fixedly arranged at one end of the rotating rod on the side surface of the installation housing, and the output end of the first motor penetrates the installation housing and is fixedly connected with the rotating rod.

[0008] By adopting the above technical solution, the output end of the first motor drives the rotating rod to rotate, thereby providing power for the subsequent movement of the left clamping plate and the right clamping plate threadedly connected to the surface of the threaded surface.

[0009] Preferably, the fixing mechanism includes a left clamping plate and a right clamping plate threadedly connected to the surface of the threaded surface. The left clamping plate and the right clamping plate move towards each other. Left convex blocks and right convex blocks are respectively fixedly arranged on the opposite sides of the left clamping plate and the right clamping plate. The left convex blocks and the right convex blocks are spliced with matching shapes. The left clamping plate and the right clamping plate are both provided with inclined grooves at the positions adjacent to the left convex blocks and the right convex blocks.

[0010] By adopting the above technical solution, the left clamping plate and the right clamping plate move towards each other, so that the left convex blocks and the right convex blocks are spliced to form a space for storing steel, and provide a fixing space for the subsequent process of abutting and fixing the steel. At the same time, the opening of the inclined grooves provides a moving track for the subsequent inclined pushing out of the inclined abutting blocks.

[0011] Preferably, the top of the left clamping plate and the right clamping plate are both provided with downward moving grooves. On one side close to the inside of the two moving grooves, reverse plates are arranged. The tops of the two reverse plates are both fixedly connected with the rotating rod. On the opposite sides of the two reverse plates, a plurality of inclined strip plates are arranged. The plurality of inclined strip plates are grouped by the connection of the two reverse plates. The two moving grooves are both provided with moving openings through the side walls at the positions of the two groups of inclined strip plates, and movable frames are movably arranged in the two groups of moving openings.

[0012] By adopting the above technical solution, a reserved space is provided by opening the movable slot, preventing the reverse plate from colliding during the opposite movement of the left clamping plate and the right clamping plate. Moreover, the movement of the left clamping plate and the right clamping plate shortens the distance from the reverse plate, thus causing the inclined strip plate to bend and providing power for the movement of the movable frame.

[0013] Preferably, a plurality of L-shaped bends are fixedly arranged on one side surface of each of the two movable frames. At the positions where the two movable frames face the plurality of left convex blocks and right convex blocks, abutting surfaces are protrudingly arranged. At the positions of the middle parts of the two movable frames corresponding to the two groups of movable openings, force-bearing cross beams are fixedly arranged, and the force-bearing cross beams are movably inserted through the movable openings. The side surfaces of the plurality of force-bearing cross beams are respectively rotatably connected to the plurality of inclined strip plates one by one.

[0014] By adopting the above technical solution, both sides of the force-bearing cross beam are fixedly connected to the movable frame to form an integral connection, and the force-bearing cross beam is rotatably connected to the inclined strip plate. When the left clamping plate and the right clamping plate move, by shortening the distance between the reverse plate and the force-bearing cross beam, the inclined strip plate is inclined to apply an inclined upward thrust to the force-bearing cross beam. And during the overall rotation of the inclined strip plate, the inclined upward thrust is converted into a vertically upward thrust, so that the force-bearing cross beam drives the movable frame to move upward along the movable opening, and the abutting surface squeezes the surface of the steel material to form a fixing effect.

[0015] Preferably, the lateral tightening mechanism includes inclined abutting blocks inserted in a plurality of inclined slots. On the side of the plurality of inclined abutting blocks away from the left clamping plate and the right clamping plate, second rotating plates are rotatably connected. The plurality of inclined abutting blocks and the plurality of second rotating plates are grouped with the left clamping plate and the right clamping plate as the demarcation points. On the opposite side surfaces of the two groups of second rotating plates, universal seats are connected. The other ends of the plurality of universal seats are fixedly connected to the plurality of L-shaped bends one by one.

[0016] By adopting the above technical solution, the second rotating plate is rotatably connected to the inclined abutting block, and the second rotating plate is connected to the L-shaped bend through the universal seat. When the movable frame moves upward, the second rotating plate is driven to move synchronously by the L-shaped bend. At the same time, the inclined abutting block takes the inner wall of the inclined slot as a fulcrum, and through the rotation conversion of the universal seat and the second rotating plate, the upward thrust is converted into an inclined thrust, so that the inclined abutting block is pushed out of the inclined slot and abuts against the surface of the steel material to form a fixation.

[0017] Preferably, synchronous rods are fixedly arranged through the middle parts of the two groups of second rotating plates. At the bottoms of the two synchronous rods, first rotating plates are rotatably connected. At the bottoms of the two first rotating plates, connecting plates are rotatably connected. At both ends of the side surface of the connecting plate close to the bottom plate, fixing pins are movably arranged.

[0018] By adopting the above technical solution, the synchronous rod drives the top of the first rotating plate to move upward under the upward thrust. At the same time, the bottom of the first rotating plate is connected to the connecting plate to form an integral fixation, enabling the first rotating plate to rotate around the connection point of the connecting plate. The inclined protrusion amplitude of the inclined abutting block is adapted to the rotation angle of the first rotating plate to form synchronous movement. While transmitting the thrust of the synchronous rod to the connecting plate, it ensures that the inclined abutting block has sufficient inclined sliding-out space to avoid dislocation.

[0019] Preferably, fixing sockets are provided on the side surfaces of the two base plates at the positions of the plurality of fixing pins, and the plurality of fixing sockets are horizontally inserted with the plurality of fixing pins.

[0020] By adopting the above technical solution, the opening of the fixing sockets provides a fixing space for the fixing pins. When the left clamping plate and the right clamping plate move to make the inclined abutting block protrude, the fixing pins are inserted into the fixing sockets to longitudinally fix the connecting plate, thereby maintaining the protruding position of the inclined abutting block.

[0021] Preferably, a plurality of insertion holes are provided on the opposite side surfaces of the two base plates, and telescopic rods are inserted in the plurality of insertion holes. A telescopic cover is fixedly provided around the plurality of telescopic rods on the opposite side surfaces of the two base plates.

[0022] By adopting the above technical solution, the plurality of telescopic rods are respectively inserted between the two base plates. When the two base plates move towards each other under the thrust, the two ends of the plurality of telescopic rods are inserted into the two base plates, forming a limit while improving stability. And the telescopic cover contracts as the two base plates move to prevent the steel parts on the surface of the base plates from falling.

[0023] Preferably, a second motor is fixedly provided at one end of the side surface of the first moving mechanism, and the output end of the second motor penetrates the side wall and is connected to the rotating shaft of the first moving mechanism.

[0024] By adopting the above technical solution, the output end of the second motor drives the rotating shaft of the first moving mechanism to rotate, so that the two second moving mechanisms move towards each other along the surface of the rotating shaft, thereby shortening the distance between the two side fixing mechanisms and clamping and fixing the steel on the surface of the base plate.

[0025] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The left clamping plate and the right clamping plate move on the surface of the rotating rod to initially clamp the steel. Then, the movement of the left clamping plate and the right clamping plate shortens the distance between the movable frame and the reverse plate, causing the pressing surface to extrude the steel upward from below. At the same time, as the movable frame moves upward, it drives the L-shaped crank and the second rotating plate to form a mutual acting force, pushing the inclined abutting block out for the second time, so that it protrudes from the inclined groove and clamps and fixes the two ends of the steel. Finally, horizontal and vertical extrusion fixation of the steel is formed, improving the fixation coefficient and effectively avoiding safety accidents caused by the steel falling off during handling. 2. By fixing small steel pieces with the left clamping plate and the right clamping plate, a storage space is reserved on the surface of the bottom plate. The large steel piece is placed on the surface of the bottom plate. As the first moving mechanism operates to drive the two second moving mechanisms to move towards each other, the large steel piece is assisted in fixing, and multiple fixed small pieces are distributed at both ends of the large steel piece, forming a cage as a whole for convenient hoisting of the large steel piece, thereby improving the applicable range of steel that can be fixed and hoisted.

[0031] It should be noted that a second motor 13 is fixedly provided on one side surface of the first moving mechanism 3, and the output shaft of the second motor 13 movably passes through the side wall and is connected to the rotating shaft of the first moving mechanism 3 through a coupling. A plurality of plug holes are horizontally opened on one side between the two base plates 7, and telescopic rods 12 are horizontally inserted into the plurality of plug holes, so that the two base plates 7 can move toward each other along the two ends of the telescopic rods 12. At the same time, a telescopic cover 8 is fixedly provided on the surface of one side between the two base plates 7 around the plurality of telescopic rods 12, and the telescopic cover 8 seals and covers the plurality of telescopic rods 12 and can shrink under pressure.

[0032] Reference Figure 4 , Figure 7, the second moving mechanism 4 includes a mounting housing 41 fixed on the surface of the rotating shaft of the first moving mechanism 3. A groove is formed upward on the lower end surface of the mounting housing 41, and a rotating rod 42 is rotatably arranged in the groove. The surface of the rotating rod 42 at the positions of a plurality of fixing mechanisms 5 is provided with a threaded surface 43. At the same time, a first motor 44 is fixed on the outer surface of the mounting housing 41 on one side of the rotating rod 42. The output shaft of the first motor 44 movably penetrates through the mounting housing 41 and is fixedly connected to the rotating rod 42 (the mounting housings 41 of the two second moving mechanisms 4 are respectively threadedly connected to both ends of the rotating shaft of the first moving mechanism 3, and the connecting threads of the two mounting housings 41 are opposite, so as to move towards each other and relatively).

[0033] Refer to Figure 2 , Figure 5 , Figure 7 , the fixing mechanism 5 includes a left clamping plate 51 and a right clamping plate 52 threadedly connected to the surface of the threaded surface 43. The threads of the left clamping plate 51 and the right clamping plate 52 are opposite. On the opposite side surfaces of the left clamping plate 51 and the right clamping plate 52, a plurality of left convex blocks 511 and right convex blocks 512 are respectively fixed. And a plurality of left convex blocks 511 and right convex blocks 512 are arranged downward along the side surfaces of the left clamping plate 51 and the right clamping plate 52. The left convex blocks 511 and the right convex blocks 512 are complementary in shape, and a notch is formed inward on the side of the left convex block 511 facing the right convex block 512. On the side of the right convex block 512 facing the left convex block 511, a convex block that fits with the notch is arranged outward. Tilted grooves 513 are formed at the positions between two adjacent left convex blocks 511 on the side surface of the left clamping plate 51 and at the positions between two adjacent right convex blocks 512 on the side surface of the right clamping plate 52; On the upper end surfaces of the left clamping plate 51 and the right clamping plate 52, movable grooves 53 are formed downward. Through holes 510 are formed through both sides of the inner walls of the two movable grooves 53 at the positions between two adjacent left convex blocks 511 and between two adjacent left convex blocks 511. A stress cross beam 59 is inserted in each of the plurality of through holes 510. At both ends of the opening of the stress cross beam 59 in the through hole 510, movable frames 56 are fixedly arranged, so as to be integrally in an I shape. On the side surfaces of the plurality of movable frames 56 at the positions of the plurality of left convex blocks 511 and right convex blocks 512, abutting surfaces 57 extend horizontally. The bottom of the abutting surface 57 is made of steel, and the top of the abutting surface 57 and the contact surface with the steel are made of rubber; At one end of the two movable grooves 53 close to each other, a reverse plate 54 is inserted. And the tops of the two reverse plates 54 are fixedly connected to the inner wall of the groove on the lower end surface of the mounting housing 41. On the opposite side surfaces of the two reverse plates 54, a plurality of inclined strip plates 55 are rotatably arranged. Under normal conditions, the plurality of inclined strip plates 55 are inclined upward by 10°. The plurality of inclined strip plates 55 are grouped by the connection of the two reverse plates 54. The plurality of inclined strip plates 55 are respectively rotatably connected to one end of the stress cross beam 59.

[0034] It should be noted that the width of the force-bearing cross beam 59 is smaller than the width of the movable opening 510, and the width of the force-bearing cross beam 59 being smaller than the width of the movable opening 510 is the moving range of the movable frame 56. At the same time, a plurality of L-shaped bends 58 are fixedly arranged on one side surface of each of the two movable frames 56.

[0035] Referring to Figure 6 、 Figure 8 , the lateral tightening mechanism 6 includes inclined abutting blocks 65 horizontally inserted into a plurality of inclined slots 513. The bottoms of the plurality of inclined abutting blocks 65 are made of steel, and the contact surfaces of the plurality of inclined abutting blocks 65 with the steel are made of rubber. One end of each of the plurality of inclined abutting blocks 65 away from the inclined slot 513 is rotatably connected to a second rotating plate 64. A universal joint 66 is fixedly arranged on the side surface of each of the plurality of second rotating plates 64. One end of each of the plurality of universal joints 66 away from the second rotating plate 64 is connected to one of the plurality of L-shaped bends 58 one by one; The plurality of inclined abutting blocks 65 and the plurality of second rotating plates 64 are grouped with the left clamping plate 51 and the right clamping plate 52 as the demarcation points. A synchronizing rod 63 is fixedly inserted through the middle of each of the two groups of second rotating plates 64. The bottoms of the two synchronizing rods 63 are rotatably connected to a first rotating plate 62. The directions of the two first rotating plates 62 are opposite, and the bottoms of the two first rotating plates 62 are rotatably connected to a connecting plate 61. A groove is formed on the side surface of the connecting plate 61 facing the bottom plate 7, and a fixed plug 67 is movably arranged at both ends of the groove. Fixed sockets 11 are inwardly opened on both ends of the side surface of the two bottom plates 7 where the fixed plug 67 is located. The fixed sockets 11 are adapted to the size of the fixed plug 67 and can be horizontally inserted.

[0036] When the left clamping plate 51 and the right clamping plate 52 move towards each other, the inclined abutting blocks 65 in the inclined slots 513 are driven to move synchronously. At the same time, as the distance between the left clamping plate 51 and the right clamping plate 52 shortens, the movable frames 56 on both sides are driven to move upward, thereby driving the L-shaped bends 58 to move upward. The L-shaped bends 58 are connected to the universal joints 66 to apply an upward thrust to the second rotating plates 64. At the same time, the second rotating plates 64 are in a rotatable connection state with the inclined abutting blocks 65, and the inclined abutting blocks 65 are integrally inserted into the inclined slots 513. When the universal joints 66 move upward, the connection nodes of the universal joints 66 and the second rotating plates 64 rotate, thereby forming an interaction force, applying a secondary thrust to the inclined abutting blocks 65, and the thrust is limited by the inclination of the inner wall of the inclined slot 513 and is converted into an inclined upward thrust to push the inclined abutting blocks 65 out secondarily, so as to abut against the steel clamped between the left clamping plate 51 and the right clamping plate 52 to prevent loosening.

[0037] Among them, the device also includes a suspension rope mechanism 2, a first motor 44, a universal joint 66, and a second motor 13, all of which are prior arts. The first motor 44 and the second motor 13 are both set as Z-series medium-sized DC motors.

[0038] The implementation principle of a steel handling and hoisting device with an anti-dropping function in an embodiment of the present invention is as follows: When using this device, the winding end of the hoisting rope mechanism 2 is relaxed to extend the internal cable, so as to place the first moving mechanism 3 near the steel to be handled. Then, the steel to be handled is inserted through the gap between the left clamping plate 51 and the right clamping plate 52, and the inserted end of the steel protrudes between another set of adjacent and parallel left clamping plate 51 and right clamping plate 52, so that the two sets of left clamping plate 51 and right clamping plate 52 as a whole support both ends of the steel. After all the steel is inserted, an electrical signal is sent through the control terminal to control the operation of the first motor 44. The output shaft of the first motor 44 drives the rotating rod 42 to rotate, so that the tops of the left clamping plate 51 and the right clamping plate 52 move towards each other along the thread surface 43. As the left clamping plate 51 and the right clamping plate 52 move to shorten the distance, the left convex block 511 and the right convex block 512 are aligned and spliced. With the opposite side walls of the left clamping plate 51 and the right clamping plate 52, a frame is formed as a whole to preliminarily fix the steel; Meanwhile, as the left clamping plate 51 and the right clamping plate 52 move, the distance between the inner wall ends of the left clamping plate 51 and the right clamping plate 52 and the movable frame 56 and the reverse plate 54 is gradually shortened, and the reverse plate 54 is integrally fixed to the installation shell 41, so that the inclined strip plate 55 and the stress cross beam 59 form an interaction force. The inclined strip plate 55 rotates counterclockwise around the connection point of the reverse plate 54, so that the connection point of the stress cross beam 59 and the inclined strip plate 55 receives an upward thrust. The stress cross beam 59 moves upward along the movable opening 510 under the thrust, and at the same time drives the movable frames 56 on both sides to move synchronously. The upward movement of the movable frame 56 drives the abutting surface 57 to push the ground of the steel upward from bottom to top, so as to squeeze the longitudinal space of the steel between the left clamping plate 51 and the right clamping plate 52 to form longitudinal fixation; When the left clamping plate 51 and the right clamping plate 52 move towards each other, since the inclined abutting block 65 is inserted into the inclined groove 513, the inclined abutting block 65 moves synchronously. At this time, the upward movement of the movable frame 56 drives the L-shaped crank 58 to move synchronously. The upward movement of the L-shaped crank 58 applies an upward thrust to one end of the universal joint seat 66, and the end of the universal joint seat 66 away from the L-shaped crank 58 is rotatably connected to the second rotating plate 64, and the second rotating plate 64 is rotatably connected to the inclined abutting block 65, so that the end of the universal joint seat 66 away from the L-shaped crank 58 is limited and fixed. At the same time, as the end of the universal joint seat 66 close to the L-shaped crank 58 receives an upward thrust, the L-shaped crank 58 and the second rotating plate 64 as a whole are bent around the universal joint seat 66; Meanwhile, the second rotating plate 64 converts the thrust formed by bending into an inclined thrust through the rotational connection with the inclined abutting block 65, and the inclined thrust is limited by the insertion of the inclined abutting block 65 into the inclined groove 513, so that one end of the second rotating plate 64 away from the universal joint 66 pushes the inclined abutting block 65 to protrude obliquely along the inclined groove 513. The two inclined abutting blocks 65 respectively protrude to form secondary clamping on both ends of the steel, thereby squeezing the gap between the steel and the side walls of the left clamping plate 51 and the right clamping plate 52 to form lateral fixation. Thus, the steel is fixed in multiple directions. After the steel is fixed, the operator laterally pushes the fixing pin 67 into the fixing socket 11 to fix the connecting plate 61, thereby fixing the synchronous rod 63 and fixing the protruding state of the inclined abutting block 65 at the current level to prevent loosening during movement.

[0039] Meanwhile, when there are large objects in the steel, the large steel can be placed on the surface of the bottom plate 7, and then the small steel is inserted into the left clamping plate 51 and the right clamping plate 52 to form a fixation. The first moving mechanism 3 operates to drive the two second moving mechanisms 4 to move towards each other, reducing the inner wall spacing of the two second moving mechanisms 4 to form an overall cage shape, thus facilitating the lifting of the large steel.

[0040] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
