Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cranes, in particular to an automatic conveying and stacking machine for metal products. BACKGROUND

[0002] Crane is a key equipment for vertical lifting and horizontal carrying of heavy objects in industrial production, and is widely used in loading and unloading and transporting operations of various metal products. However, the existing crane has obvious defects in the transfer process of cylindrical metal materials such as steel bars, mainly in the following aspects:

[0003] The traditional steel bar transfer method is usually to simply bundle a plurality of steel bars and then hoist and carry the whole by crane hook. Since the steel bar is cylindrical and smooth, it is difficult to achieve complete fixation during bundling, and there is often a gap between the steel bars. During hoisting and carrying, this unstable structure is prone to cause safety hazards due to the following reasons:

[0004] 1. Loose bundling: the bundling rope is loosened due to vibration or bumping during transportation;

[0005] 2. Dynamic deviation: especially in adverse weather conditions such as strong wind, the steel bar bundle will sway left and right during hoisting, causing the center of gravity to deviate, and in severe cases it may fall from the air;

[0006] 3. Manual dependence: relying on manual operation and visual inspection, the transfer efficiency is low and the safety risk is high.

[0007] The above problems not only reduce the safety of steel bar transfer, but also increase the risk of injury to operators or damage to equipment, especially in high-frequency application scenarios such as construction sites and steel mills. Therefore, it is urgent to develop a special automatic conveying and stacking device for metal products (especially cylindrical steel bars). SUMMARY

[0008] The purpose of the present application is to provide a special conveying and stacking machine for cylindrical metal products, which replaces manual bundling with mechanical limiting and eliminates dynamic deviation through intelligent control, thereby realizing safe, efficient and stable steel bar transfer and stacking operation, and making up for the functional deficiency of traditional cranes in this field.

[0009] To achieve the above purpose, the present application provides the following technical scheme: an automatic conveying and stacking machine for metal products, comprising a crane main body, a lifting rope and a supporting leg, a lifting mechanism for lifting a steel bar bundle is arranged on the lifting rope, and a tightening mechanism for adjusting the angle between the lifting mechanism and the steel bar bundle is arranged on the lifting mechanism.

[0010] And the lifting mechanism is further provided with a pressing mechanism connected with the tightening mechanism, when the lifting mechanism lifts and hoists the reinforcement bundle by the tightening mechanism, the pressing mechanism drives the tightening mechanism to lift the two side parts of the reinforcement bundle and press the middle part.

[0011] As a preferred, the lifting mechanism comprises a lifting cylinder installed on the lifting rope, a fixing seat installed on the lifting cylinder, a rolling disc installed on the fixing seat, the rolling disc being wound by the lifting rope, a limiting disc installed at the bottom end of the lifting cylinder, a winch installed on the lifting cylinder, and a steel rope oppositely installed on the winch and wound in the opposite direction.

[0013] As a preferred, the pressing mechanism comprises a rod I installed through the inside of the lifting cylinder, an arc-shaped plate installed at the bottom end of the rod I, a recess I oppositely opened on the rod I, an axle installed through the recess I, a support rod installed in the recess I and penetrated by the axle, a spiral groove opened on the outer wall of the lifting cylinder, a sleeve ring I installed on the lifting cylinder, a protrusion installed on the inner wall of the sleeve ring I, the protrusion being a plurality of and arranged along the spiral groove, a sleeve ring II oppositely installed on the winch, an arc-shaped seat oppositely installed on the sleeve ring II, a hole oppositely opened on the arc-shaped seat, and the hole being penetrated by the steel rope.

[0014] And a connecting component is installed on the winch and the sleeve ring I, the connecting component connecting the tightening mechanism and the pressing mechanism together.

[0015] As a preferred, the connecting component comprises a fixing ring installed on the winch, a rotating rod oppositely installed on the fixing ring, a clamping groove opened on the rotating rod, a recess II oppositely opened on the sleeve ring I, and a rod II installed through the recess II.

[0016] And a lifting piece is installed at one end of the steel rope, the lifting piece being connected with the object to be lifted.

[0017] As a preferred, the lifting piece comprises a hook.

[0018] As a preferred, the lifting piece comprises a connecting rope installed at the top end of the steel rope, the connecting rope being a plurality of, a steel plate installed on the connecting rope, the steel plate being a plurality of and penetrated by the connecting rope, and an anti-skid pattern opened on the steel plate.

[0019] And a limiting mechanism is installed on the lifting piece, the limiting mechanism making the steel plate more closely attached to the reinforcement bundle.

[0020] Preferably, the limiting mechanism comprises a chain installed on the steel plate at the bottom end, and a lock installed on the steel plate at the top end.

[0021] Preferably, the length of the rotating rod on the fixing ring is 15-25 cm.

[0022] Preferably, a strong magnet is installed in the hanging cylinder.

[0023] The present application has at least the following advantages:

[0024] Firstly, the present application realizes dynamic adjustment and locking of the inclination angle between the hoisting rope and the hoisted object during the hoisting process through the cooperative control of the tightening mechanism and the hoisting mechanism, thereby ensuring uniform and stable stress during the hoisting process and improving the safety and applicability of the hoisting operation.

[0025] Secondly, under the driving of the pressing mechanism, when the steel bundle is hoisted, the connection between the hoisting rope and the steel bundle can be actively lifted, and a downward pressing force is applied to the middle part of the steel bundle, forcing the steel bundle to form a wave-shaped structure. This design increases the friction between the hoisting rope and the steel bundle, effectively avoiding the risk of steel bundle slipping due to sliding or yawing.

[0026] In addition, the hoisting piece significantly increases the contact area with the steel bundle through optimized structural design, thereby greatly reducing the possibility of the steel bundle shaking or displacing due to the action of inertial force during the hoisting process, further improving the safety and reliability of the transfer process.

[0044] a pressing mechanism 6 installed on the hoisting mechanism 4 and connected with the tightening mechanism 5, used for lifting the two side parts of the steel reinforcement bundle by the tightening mechanism 5 and pressing the middle part.

[0045] Specifically:

[0046] The hoisting mechanism 4 comprises a hoisting cylinder 41 mounted on the hoisting rope 2, a fixing seat 42 mounted on the hoisting cylinder 41, and a rolling disc 43 mounted on the fixing seat 42 and wound by the hoisting rope 2.

[0047] The hoisting cylinder 41 is provided at the bottom end with a limiting disc 44, and the hoisting cylinder 41 is provided with a winch 45, and the winch 45 is oppositely provided with a steel wire rope 46 which is oppositely wound.

[0048] The tightening mechanism 5 comprises a sliding groove 51 oppositely formed on the hoisting cylinder 41, a ratchet disc I 52 sleeved on the hoisting cylinder 41, a sliding block 53 oppositely mounted on the inner wall of the ratchet disc I 52, and the sliding block 53 corresponding to the sliding groove 51.

[0049] The tightening mechanism 5 further comprises a ratchet disc II 54 mounted at the bottom end of the winch 45, and the ratchet disc II 54 is oppositely arranged with the ratchet disc I 52.

[0050] The compression mechanism 6 comprises a rod I 60 penetratingly mounted in the hoisting cylinder 41, and the rod I 60 is provided at the bottom end with an arc-shaped plate 61.

[0051] The rod I 60 is oppositely provided with a groove I 62, and the groove I 62 is penetratingly mounted with an axle 63, and the groove I 62 is mounted with a supporting rod 64 which is penetratingly mounted with the axle 63.

[0052] The hoisting cylinder 41 is oppositely provided with a spiral groove 65, and the hoisting cylinder 41 is mounted with a sleeve ring I 66, and the sleeve ring I 66 is mounted with a protruding block 67 on the inner wall, and the protruding block 67 is provided in plurality and arranged along the spiral groove 65.

[0053] The winch 45 is oppositely mounted with a sleeve ring II 68, and the sleeve ring II 68 is oppositely mounted with an arc-shaped seat 69, and the arc-shaped seat 69 is oppositely provided with a hole 610 which is penetratingly mounted with the steel wire rope 46.

[0054] The winch 45 and the sleeve ring I 66 are mounted with a connecting component 7 which connects the tightening mechanism 5 and the compression mechanism 6.

[0055] Working principle:

[0056] Working mode of the tightening mechanism 5:

[0057] After the steel wire rope 46 is connected with the object to be hoisted, the winch 45 is lifted upward, and then the winch 45 is rotated, and since the steel wire rope 46 is oppositely arranged, when the winch 45 is rotated, the steel wire ropes 46 on both sides are synchronously contracted or released.

[0058] When the steel rope 46 is adjusted to the appropriate length, the winch 45 is loosened, and under the action of gravity, the ratchet disc one 52 and the ratchet disc two 54 are locked with each other, the sliding block 53 in the ratchet disc one 52 is clamped with the sliding groove 51, and the rotation cannot be performed, so that the steel rope 46 cannot be pulled in the hoisting process.

[0059] The working mode of the pressing mechanism 6 is as follows:

[0060] The rod one 60 and the lifting cylinder 41 are gap-connected, and the sleeve ring two 68 has the same effect as the bearing;

[0061] The holes 610 on the arc-shaped seat 69 are penetrated by the steel rope 46 on the winch 45, and the relatively arranged and same height holes 610 balance the steel rope 46, so that the hoisting process is more stable;

[0062] The connecting component 7 comprises a fixed ring 71 mounted on the winch 45, the fixed ring 71 is relatively mounted with a rotating rod 72, the rotating rod 72 is provided with a clamping groove 73, the sleeve ring one 66 is relatively provided with a recess two 74, and the rod two 75 is penetrated and mounted in the recess two 74;

[0063] The hoisting component 8 is mounted at one end of the steel rope 46, and the hoisting component 8 is connected with the object to be hoisted.

[0064] The special hoisting mode for the steel bar bundle is as follows:

[0065] When the hoisted object is the steel bar bundle, the winch 45 and the ratchet disc one 52 are lifted upward, and then another operator clamps the clamping groove 73 on the rotating rod 72 with the rod two 75 on the sleeve ring one 66, so that the winch 45 and the sleeve ring two 68 are connected as a whole;

[0066] The supporting rod 64 is rotated, and under the support of the recess one 62, the supporting rod 64 is perpendicular to the lifting cylinder 41, at this time, the control on the winch 45 and the ratchet disc one 52 is released, and under the action of gravity, the winch 45 drives the sleeve ring two 68 to be attached to the supporting rod 64;

[0067] The main body 1 of the crane is started, under the strong gravity of the steel bar bundle, the winch 45 drives the ratchet disc one 52 to press down the supporting rod 64, in the process of pressing down, the sleeve ring two 68 at the top of the winch 45 drives the winch 45 to rotate under the action of the convex block 67 and the spiral groove 65, the steel rope 46 is further contracted, and is wound on the arc-shaped seat 69, so that the pulling force at the connection between the lifting and the steel bar is improved;

[0068] At the same time, the downward movement of the supporting rod 64 drives the arc-shaped plate 61 at the top of the rod one 60 to press the middle part of the steel bar bundle, and the two ends of the steel bar bundle are in a drooping state under the action of gravity, at this time, the whole steel bar bundle presents a wave shape, which greatly reduces the risk of steel bar sliding in the transfer process, and the toughness makes it possible to restore to the original state after the pressing force is removed.

[0069] It should be noted that the hoisting member 8 includes hooks 800, which can also be used when hoisting other objects.

[0070] Embodiment 2

[0071] On the basis of embodiment 1, another optimization of the hoisting member 8 is proposed in the present application:

[0072] The hoisting member 8 includes connecting ropes 81 installed at the top end of the steel rope 46, and the connecting ropes 81 are provided with steel plates 82, which are penetrated by the connecting ropes 81 and are provided with anti-skid lines 83.

[0073] And a limiting mechanism 9 is installed on the hoisting member 8, which makes the steel plate 82 and the steel bundle fit more closely.

[0074] The steel plate 82 greatly increases the contact area between the hoisting part and the steel bundle, the anti-skid lines 83 increase the friction between the steel bundle and the steel plate 82, which reduces the risk of sliding of the steel bundle during transportation, and the safety is higher.

[0075] The limiting mechanism 9 includes a lock chain 91 installed on the steel plate 82 at the bottom end, and a lock buckle 92 installed on the steel plate 82 at the top end.

[0076] After the iron ring in the lock chain 91 is clamped with the lock buckle 92, the steel plate 82 and the steel bundle fit more closely.

[0077] Embodiment 3

[0078] On the basis of embodiments 1 and 2, the present application further optimizes the scheme:

[0079] The length of the rotating rod 72 on the fixing ring 71 is 15-25 cm, and when the winch 45 rotates, the rotating rod 72 can be directly used as a handle to make the steel rope 46 more convenient to retract and release.

[0080] The strong magnet 47 is installed in the hoisting cylinder 41, so that the rod 60 can be well fixed in the hoisting cylinder 41 even when not in use, reducing the occupied space, and when in use, the gravity of the steel bundle can easily break through the adsorption force, without affecting the operation of the crane.

[0081] The whole process of lifting the steel bundle is as follows: the steel plate 82 is wound on both sides of the steel bundle, then the lock chain 91 is fixed by the buckle, then the winch 45 and the ratchet disc 1 52 are lifted and rotated, at this time, the other operator makes the clamping groove 73 on the rotating rod 72 and the rod 2 75 on the ring 1 66 engaged, so that the winch 45 and the ring 2 68 are connected as a whole, then the supporting rod 64 is rotated, and under the support of the groove 1 62, the supporting rod 64 and the lifting cylinder 41 are perpendicular to each other, at this time, the control of the winch 45 and the ratchet disc 1 52 is released, under the action of gravity, the winch 45 drives the ring 2 68 to adhere to the supporting rod 64, then the main body 1 of the crane is started, under the strong gravity of the steel bundle, the winch 45 drives the ratchet disc 1 52 to press down the supporting rod 64, in the process of pressing down, the ring 2 68 at the top of the winch 45 drives the winch 45 to rotate under the action of the convex block 67 and the spiral groove 65, the steel rope 46 is further contracted and wound on the arc-shaped seat 69, the tension at the connection between the lifting and the steel is improved, at the same time, the downward movement of the supporting rod 64 drives the arc-shaped plate 61 at the top of the rod 1 60 to press the middle part of the steel bundle, and the two ends of the steel bundle are in a drooping state under the action of gravity, at this time, the whole steel bundle presents a wavy shape, and is transported to a suitable place.
