Description

Technical Field

[0001] The invention relates to the technical field of intelligent steelmaking, and in particular to a long shroud holder hoisting fixture and a hoisting system. Background Art

[0002] In modern industrial casting or smelting processes, the shroud is a key component connecting the smelting furnace and the pouring system. Its regular replacement is essential to ensure production continuity and product quality. However, in the traditional operation mode, the replacement of the shroud mainly relies on manual operation, which has many inconveniences and safety hazards.

[0003] Specifically, every time the robot completes a certain number of pouring tasks (such as 8 bags), it needs to replace the new shroud. Since the shroud itself is heavy, weighing 120 kilograms together with the gripper, it is extremely laborious to carry it manually, which not only increases the labor intensity of the operator, but also may lead to low handling efficiency and affect the overall production progress.

[0004] What is more serious is that the shroud is often in a high temperature state after long-term use, and the temperature can be as high as more than 900 degrees. This extreme high temperature environment makes it extremely dangerous for humans to directly touch the shroud. The operator must wait for several hours (such as 7-8 hours) for it to cool down naturally before replacing it, which undoubtedly greatly prolongs the downtime and reduces the efficiency of the robot operation. At the same time, working in a high temperature environment also increases the risk of safety accidents such as burns, posing a serious threat to the health of the operator.

[0005] In view of the above problems, the current manual shroud replacement method can no longer meet the needs of efficient and safe production. Therefore, there is an urgent need for a solution that can automatically, efficiently and safely complete the shroud replacement.

[0011] In a further embodiment of the present application, when the movable part of the clamp slides along the extension bracket in a direction close to the clamp body, a number of jaw assemblies are gradually unfolded; when the movable part of the clamp slides in a direction away from the clamp body, a number of jaw assemblies are gradually clamped; wherein, the constraint portion is initially in the second posture, at which time the jaw assembly is unfolded; when the clamp body contacts the long water nozzle clamp, the constraint portion and the bottom of the locking groove trigger contact, the constraint portion switches from the second posture to the first posture, and the movable part of the clamp gradually slides away from the clamp body under lifting, so that the jaw assembly clamps the long water nozzle clamp.

[0012] In a further embodiment of the present application, the extension bracket includes a slide groove, and the clamp movable part includes: a second mounting frame; a sliding portion, a sliding portion arranged at the edge of the second mounting frame and protruding radially to extend into the slide groove to slideably connect the extension bracket; a connecting portion, arranged on a side of the second mounting frame facing the clamp body, and the hanger opener is connected to the connecting portion.

[0013] In a further embodiment of the present application, the movable part of the clamp further includes a lifting ring portion, which is disposed on a side of the second mounting frame away from the connecting portion, and is used to provide lifting and mounting.

[0014] In a further embodiment of the present application, the movable part of the clamp further includes an anti-collision block, and the anti-collision block is arranged on the sliding block.

[0015] In a further embodiment of the present application, a plurality of rotating hinge seats are arranged on the first mounting frame, and the movable part of the clamp also includes a plurality of rotating mounting blocks, which radially protrude from the outer arm of the connecting part, and the clamp assembly includes: a swivel arm, one end of which is rotatably connected to the rotating hinge seat; a clamp arm, including a transmission part and a clamp part which are arranged at angles to each other, one end of the transmission part is rotatably connected to the other end of the swivel arm, and the connection between the transmission part and the clamp part is rotatably connected to the rotating hinge seat.

[0016] In a further embodiment of the present application, the first mounting frame includes a first beam structure and a second beam structure, and the first beam structure and the second beam structure are respectively arranged in sequence and at equal intervals in the circumferential direction, and the retaining groove is arranged at the connection center of the first beam structure and the second beam structure; wherein, the extension bracket is arranged on the first beam structure and arranged along the connection center annular array, and the rotating hinge seat is arranged on the second beam structure and arranged along the connection center annular array.

[0018] In summary, the present invention provides a method which has at least the following beneficial effects:

[0019] It should be noted that the lifting clamp provided in the embodiment of the present invention can be in a state where the jaw assembly is expanded when it is lifted but not clamping the long nozzle clamp. At this time, the clamp movable part is constrained by the action of the lifting clamp opener and closer; when in contact with the long nozzle clamp, the lifting clamp opener and closer is unlocked to allow the clamp movable part to slide upward. When being lifted and clamping the long nozzle clamp, the clamp movable part slides upward to achieve the clamping of the long nozzle clamp by several jaw assemblies.

[0020] By sliding the movable part of the clamp on the extension bracket, the clamping and expansion of the clamping jaw assembly can be quickly controlled, thereby achieving rapid clamping of the long nozzle. This quick response mechanism reduces the time required to replace or adjust the long nozzle, improving the overall efficiency of the production line.

[0021] The design of the lifting fixture makes the clamping operation simple and direct, without the need for complex motor drive and control, reducing the difficulty of operation and the error rate. That is, by reducing complex mechanical and electronic components, production efficiency is further improved and costs are reduced.

[0022] In addition, the clamping jaw assembly can realize a deadweight interlocking mechanism, that is, the deadweight of the long water outlet can drive the movable parts of the clamp to slide, thereby further enabling the clamping jaw assembly to continuously clamp the long water outlet tightly and stably, preventing the claw from coming off during lifting or transportation, thereby avoiding potential safety accidents.

[0044] like Figure 1 to Figure 2 A long shroud clamp lifting fixture 100 provided in an embodiment of the present invention includes a fixture body 10, a fixture movable part 20, a lifting fixture opener and closer 30, and a plurality of clamping jaw groups 40.

[0045] Among them, the clamp body 10 includes a first mounting frame 11 and a locking groove a set on the first mounting frame 11, and a plurality of extension brackets 12 set around the locking groove a and protruding relative to the first mounting frame 11; the clamp movable part 20 is slidably connected to the extension bracket 12; the hanger opener and closer 30 is connected to the clamp movable part 20 so as to be able to extend into the locking groove a and unlock or lock the locking groove a; a plurality of clamp jaw assemblies 40 are respectively movably connected to the clamp body 10 and the clamp movable part 20; wherein, the clamp movable part 20 slides on the extension bracket 12 so as to control the plurality of clamp jaw assemblies 40 to clamp or unfold each other with the locking groove a as the center.

[0046] Specifically, the first mounting frame 11 serves as a supporting structure for the entire clamp, providing a stable installation. A retaining groove a is provided on the first mounting frame 11; an extension bracket 12 is provided around the retaining groove a and protrudes relative to the first mounting frame 11, which provides a linear track for sliding of the clamp movable part 20. The clamp movable part 20 can slide along the extension bracket 12, so that the clamp movable part 20 can adjust its position. A hanger opener and closer 30 is connected to the clamp movable part 20, so that the hanger opener and closer 30 can move with the movement of the clamp movable part 20, thereby realizing the unlocking or locking operation of the retaining groove a. That is, by cooperating with the hanger opener and closer 30 and the retaining groove a, it is possible to constrain or release the freedom of movement of the clamp movable part 20 in the sliding direction.

[0047] The principle of the sling opening and closing device 30 is to extend into the locking groove a to perform unlocking or locking operations. When it is necessary to restrict the movement of the clamp movable part 20, the sling opening and closing device 30 will cooperate with the locking groove a accordingly to achieve the switching of the state.

[0048] The principle of the sling opener and closer 30 is to extend into the retaining groove a to perform unlocking or locking operations. When it is necessary to restrict the movement of the clamp movable part 20, the sling opener and closer 30 will cooperate with the retaining groove a accordingly to achieve the state switching; among them, "unlocking" can be simply interpreted as: allowing the sling opener and closer 30 to move out of the retaining groove a; on the contrary, "locking" means that the sling opener and closer 30 cannot move out of the retaining groove a.

[0049] The clamping jaw assembly 40 is movably connected to the clamp body 10 and the clamp movable part 20. This connection mode enables the clamping jaw assembly 40 to perform corresponding actions as the clamp movable part 20 moves. That is, through the sliding of the clamp movable part 20 on the extension bracket 12, the clamping jaw assembly 40 can clamp or expand each other with the clamping groove a as the center. This design enables the clamp to flexibly adapt to long shrouds of different sizes and shapes, ensuring the stability and reliability of clamping.

[0050] Specifically, in the initial state, the entire hoisting fixture is in a suspended state; at this time, the fixture movable part 20 is located at a certain initial position in the middle of the extension bracket 12, and the clamping jaw assembly 40 is in an extended state, the sling opener 30 and the locking groove a are locked, and the fixture movable part 20 cannot slide upward. When it is necessary to clamp the long nozzle, the sling opener 30 is triggered to cooperate with the locking groove a to perform an unlocking operation, and then the fixture movable part 20 is allowed to slide upward along the extension bracket 12 under the drive of external power (such as the pulling force of the lifting rope), thereby driving the clamping jaw assembly 40 to move toward the center of the locking groove a and gradually clamp the long nozzle.

[0051] It should be noted that the hoisting fixture provided in the embodiment of the present invention can be in the state where the jaw assembly 40 is expanded when it is hoisted but not clamping the long water nozzle clamp. At this time, the clamp movable part 20 cannot slide upward under the action of the hoist opener and closer 30; when it contacts the long water nozzle clamp, the hoist opener and closer 30 is unlocked to allow the clamp movable part 20 to slide upward. When it is hoisted and clamps the long water nozzle clamp, the clamp movable part 20 slides upward to achieve a plurality of jaw assemblies 40 clamping the long water nozzle clamp. By sliding the clamp movable part 20 on the extension bracket 12, the clamping and expansion of the jaw assembly 40 can be quickly controlled, thereby achieving rapid clamping of the long water nozzle. This rapid response mechanism reduces the time required to replace or adjust the long water nozzle, and improves the overall efficiency of the production line.

[0052] The design of the hoisting fixture 100 makes the clamping operation simple and direct, without the need for complex motor drive and control, reducing the difficulty of operation and the error rate, and further improving production efficiency. The clamping jaw assembly 40 can tightly and stably clamp the long shroud to prevent it from falling off or shaking during hoisting or transportation, thereby avoiding potential safety accidents.

[0053] In a specific embodiment, the hanger closer 30 includes a main body 31 , a rotating pin 32 and a restraining portion 33 ; when the restraining portion 33 contacts and collides with the bottom of the retaining groove a, the rotating pin 32 can be extended and retracted and rotated at the same time to change the posture of the restraining portion 33 .

[0054] It is understandable that when the clamp movable part 20 drives the hanger shutter 30 to approach the locking groove a, the restraining part 33 first contacts and collides with the bottom of the locking groove a. The contact collision is a signal to trigger the rotation pin 32 to move.

[0055] like Figures 3 to 5 , under the action of the restraining part 33 contacting and colliding with the bottom of the locking groove a, the rotating pin 32 begins to expand and contract and rotate at the same time. This composite motion changes the posture of the restraining part 33 relative to the locking groove a, and locking / unlocking is achieved through the posture change:

[0056] First posture (unlocked state): When the restraining portion 33 is in the first posture, the matching relationship between it and the retaining groove a allows the clamp movable part 20 to slide freely along the extension bracket 12. At this time, the hanger shutter 30 is in the unlocked state, and the clamp movable part 20 can slide along the extension bracket 12 without restriction.

[0057] Second posture (locked state): When the rotating pin 32 further retracts and rotates, so that the restraining portion 33 is transformed into the second posture, the matching relationship between it and the locking groove a changes, forming a locking relationship. At this time, the position of the clamp movable part 20 is fixed and cannot slide upward along the extension bracket 12.

[0058] In a preferred solution of an embodiment of the present invention, the retaining groove a is a strip groove; in a first posture, the constraint portion 33 and the retaining groove a are parallel so as to be able to pass through the retaining groove a; in a second posture, the constraint portion 33 and the retaining groove a are at 90° so as to abut against the top of the retaining groove a; each time the constraint portion 33 contacts and collides with the bottom of the retaining groove a, the rotating pin 32 retracts and extends and rotates 90° at the same time.

[0059] It can be understood that the retaining groove a is a groove with a certain depth, and this depth is the vertical distance from the bottom of the groove to the groove opening. The bottom refers to the groove bottom, which is the lowest surface of the retaining groove a and the lower boundary of its cross section. In this application, the top specifically refers to the lower edge of the groove opening, that is, the surface opposite to the groove bottom and the part that forms the groove opening. (Refer to a1 and a2 in the figure, which respectively indicate the top and bottom).

[0060] That is, in the first posture, the constraint portion 33 and the retaining groove a remain parallel, and this arrangement enables the constraint portion 33 to pass through the retaining groove a smoothly, achieving unimpeded movement or adjustment. When the second posture is reached, the angle between the constraint portion 33 and the retaining groove a becomes 90°, that is, it is in a vertical state. At this time, the top of the constraint portion 33 and the retaining groove a abut against each other, forming a stable locking relationship, preventing further movement or adjustment. This posture ensures that the device can remain fixed when needed, enhancing safety and stability.

[0061] Continue reading Figure 1 and Figure 2 In the embodiment of the present invention, when the movable member 20 of the clamp slides along the extension bracket 12 toward the clamp body 10, the plurality of jaw assemblies 40 gradually unfold; when the movable member 20 of the clamp slides toward the direction away from the clamp body 10, the plurality of jaw assemblies 40 gradually clamp.

[0062] Among them, the constraint part 33 is initially in the second posture, and the jaw assembly 40 is unfolded; when the clamp body 10 contacts the long water nozzle clamp, the constraint part 33 and the bottom of the locking groove a trigger contact, and the constraint part 33 switches from the second posture to the first posture, and the clamp movable part 20 gradually slides away from the clamp body 10 under lifting, so that the jaw assembly 40 clamps the long water nozzle clamp.

[0063] like Figure 6 In an embodiment of the present invention, the extension bracket 12 includes a slide groove b, and the clamp movable part 20 includes a second mounting frame 21, a sliding block portion 22 and a connecting portion 23. The sliding block portion 22 is arranged on the edge of the second mounting frame 21 and protrudes radially to extend into the slide groove b to slide and connect the extension bracket 12; the connecting portion 23 is arranged on a side of the second mounting frame 21 facing the clamp body 10, and the hanger opener 30 is connected to the connecting portion 23.

[0064] Furthermore, the slideway b is arranged in the vertical direction, which not only provides a moving track for the clamp movable part 20, but also limits the moving direction and range of the clamp movable part 20 through its structure. During the hoisting process, the clamp movable part 20 can move along a predetermined path, thereby achieving precise clamping action.

[0065] The slider portion 22 is a portion of the second mounting bracket 21 protruding radially from the edge thereof, and its shape and size match the slide slot b. The slider portion 22 extends into the slide slot b and forms a sliding fit with the slide slot b, thereby realizing a sliding connection between the clamp movable part 20 and the extension bracket 12. This design enables the clamp movable part 20 to perform a linear lifting motion along the slide slot b.

[0066] The connection part 23 is provided on a side of the second mounting frame 21 facing the clamp body 10, and is used to connect the hanger switch 30. The design and position selection of the connection part 23 take into account the installation requirements and operational convenience of the hanger switch 30. Through the connection part 23, the hanger switch 30 can be firmly fixed on the clamp movable part 20 and move with the movement of the clamp movable part 20.

[0067] In the embodiment of the present invention, the clamp movable part 20 further includes a lifting ring 24, which is arranged on the side of the second mounting frame 21 away from the connecting part 23. The main function of the lifting ring 24 is to provide a lifting mounting point. Through this mounting point, the clamp movable part 20 can be lifted as a whole using a lifting device (such as a crane, a hook, etc.). The long nozzle clamp connected thereto can be transferred and installed between different locations or equipment.

[0068] In an embodiment of the present invention, the clamp movable part 20 also includes an anti-collision block 25, and the anti-collision block 25 is arranged on the sliding block part 22; the anti-collision block 25 can provide an elastic contact surface when the clamp movable part 20 approaches the extreme position of the slide groove b, thereby preventing the clamp movable part 20 from making rigid contact with the extension bracket 12 during movement.

[0069] In the embodiment of the present invention, a plurality of rotating hinge seats 13 are arranged on the first mounting frame 11, and the clamp movable part 20 also includes a plurality of rotating mounting blocks 26, which radially protrude from the outer arm of the connecting part 23, and the clamping jaw assembly 40 includes a rotating arm 41 and a clamping jaw arm 42.

[0070] One end of the rotating arm 41 can be rotatably connected to the rotating hinge seat 13; the clamping arm 42 includes a transmission part 421 and a clamping part 422 arranged at an angle to each other, one end of the transmission part 421 can be rotatably connected to the other end of the rotating arm 41, and the connection between the transmission part 421 and the clamping part 422 can be rotatably connected to the rotating hinge seat 13.

[0071] The rotating hinge 13 provides a rotatable connection point for other parts of the clamp. The design of the rotating hinge 13 allows the connected parts to rotate freely within a certain range, thereby realizing the motion trajectory of clamping or unfolding. The rotating arm 41 and the clamping claw arm 42 constitute a connecting rod, wherein the rotational freedom at both ends of the rotating arm 41 is not constrained, and the clamping claw arm 42 is composed of a transmission part 421 and a clamping claw part 422, which are arranged at an angle to each other to meet the morphological requirements of the clamping long water nozzle clamp; at the same time, the design enables the clamping claw arm 42 to produce a certain lever effect during the transmission process to enhance the clamping force, and one end of the transmission part 421 can be rotatably connected to the other end of the rotating arm 41, so that the rotational movement of the rotating arm 41 can be transmitted to the transmission part 421, thereby driving the movement of the entire clamping claw arm 42.

[0072] 1) When the lifting fixture is in the process of suspension and does not clamp the long nozzle clamp, the lifting fixture opener 30 extends into the locking groove a and the restraining part 33 is in the second posture. At this time, the lifting fixture opener 30 and the locking groove a are locked, the clamp movable part 20 is located at a certain initial position in the middle and is constrained from sliding upward, and the plurality of jaw assemblies 40 are in the expanded state to better cover the long nozzle clamp to avoid structural interference.

[0073] 2) When the lifting fixture contacts the long nozzle clamp, the lifting fixture is supported, the lifting pulling force is cancelled, and the restraining part 33 contacts and collides with the bottom of the locking groove a under the gravity of the fixture movable part, thereby switching the state from the second posture to the first posture, and the fixture movable part 20 is allowed to slide upward;

[0074] 3) Lift the movable part 20 of the clamp upwards. At this time, the movable part 20 of the clamp slides upwards under the guidance of the extension bracket 12, and at the same time drives the clamping jaw assembly 40 connected thereto to move together. During the movement, the rotating arm 41 rotates around the rotating hinge seat 13, and then drives the clamping jaw arm 42 to move through the transmission part 421. Driven by the transmission part 421, the clamping jaw part 422 of the clamping jaw arm 42 gradually approaches the long water nozzle clamp to achieve the clamping action. Since the transmission part 421 and the clamping jaw part 422 and the rotating arm 41 and the transmission part 421 are rotatably connected through the rotating hinge seat 13, the entire clamping jaw assembly 40 can be adjusted in multiple degrees of freedom to meet complex clamping requirements.

[0075] like Figure 7 In the embodiment of the present invention, the first mounting frame 11 includes a first beam structure 111 and a second beam structure 112, the first beam structure 111 and the second beam structure 112 are respectively arranged at equal intervals in the circumferential direction, and the retaining groove a is arranged at the connection center of the first beam structure 111 and the second beam structure 112; wherein, the extension bracket 12 is arranged on the first beam structure 111 and arranged along the connection center annular array, and the rotating hinge seat 13 is arranged on the second beam structure 112 and arranged along the connection center annular array. The first beam structure 111 and the second beam structure 112 constitute the main part of the first mounting frame 11. By arranging the first beam structure 111 and the second beam structure 112 at equal intervals in the circumferential direction, this layout helps to disperse and evenly carry the forces from all directions, thereby improving the structural stability and strength of the entire mounting frame. The extension bracket 12 and the rotating hinge seat 13 are arranged along the connection center annular array, which further enhances the rigidity and torsion resistance of the mounting frame. This design enables the mounting frame to more effectively resist deformation and damage when subjected to external forces.

[0076] Furthermore, those skilled in the art should understand that if all or part of the sub-modules involved in the various products of the long water nozzle clamp lifting fixture 100 provided in the embodiment of the present invention are combined and replaced by fusion, simple change, mutual conversion, etc., such as the components are placed and moved, or designed to be detachable; such as a split design; all the combined components can form equipment / devices / systems with specific functions, using such equipment / devices / systems to replace the corresponding components of the present invention also falls within the protection scope of the present invention.

[0077] like Figure 8 and Fig. 9 The second aspect of the present application further provides a hoisting system 200, comprising the above-mentioned shroud holder hoisting fixture 100, a shroud holder 201, a shroud storage rack 202 and a hoisting device 203;

[0078] The long water nozzle clamp 201 is arranged on the outer periphery of the long water nozzle, and a plurality of opening grooves c are sequentially arranged on the circumference of the long water nozzle clamp 201.
