Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stainless steel smelting equipment, specifically a fixed crane clamp. Background Technology
[0002] After being produced by continuous casting, the steel billets are conveyed to the billet discharge position by roller conveyors and then hoisted to the billet yard by overhead cranes. At the same time, when the steel billets leave the factory, they also need to be hoisted and loaded onto trucks by overhead cranes. The overhead cranes they purchased are designed to be rotatable, with the intention of adjusting the position of the steel billets by rotating them with a motor, thereby achieving the purpose of neat stacking.
[0003] However, in actual use, due to the high temperature (≥800℃) and heavy weight (21-23 tons) of the steel billets, motor failures are inevitable. Once the motor fails, the overhead crane clamp cannot adjust its angle. When lifting the steel billets, due to the large weight and inertia of the billets, the overhead crane clamp will inevitably shake and deflect, resulting in uneven stacking of the billets. Uneven stacking not only affects the stacking height of the billets but also poses a safety hazard of billet tipping. Furthermore, it prevents the installation of insulation covers during loading, affecting billet production efficiency. Replacing the overhead crane clamp after a motor failure is not only time-consuming but also wastes equipment. Utility Model Content
[0004] The purpose of this invention is to provide a fixed crane clamp to solve the problems mentioned in the background art.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A fixed-type traveling jig, comprising a top mechanism, a rotary drive mechanism, a connecting beam, a clamping mechanism, and a fixing bracket, wherein: The top mechanism includes a hanging beam and a hanging ear, the hanging beam extends along a first direction, the hanging ear is fixedly connected to the hanging beam, and the hanging ear is used to connect the overhead crane mechanism at the top, and the crane mechanism can control the movement of the traveling jig; The rotary drive mechanism includes a motor and a transmission gear, the body of the motor is fixedly connected to the hanging beam, the output end of the motor is in transmission connection with the transmission gear, the transmission gear is disposed between the hanging beam and the connecting beam, and one end of the transmission gear is rotatably connected to the hanging beam, and the other end is fixedly connected to the connecting beam, and the motor can drive and control the hanging beam and the connecting beam to rotate relative to each other about a second direction as an axis, the second direction is the lifting and lowering direction of the traveling jig for hoisting, and the second direction is perpendicular to the first direction; The clamping mechanism is installed on the connecting beam and is used for clamping and opening the steel billet being hoisted; The fixing bracket is divided into a first fixing portion and a second fixing portion. When the fixing bracket is in a locked state, the first fixing portion is used for limiting the hanging beam, and the second fixing portion is used for limiting the connecting beam, and the fixing bracket forms a limiting mechanism, and multiple such limiting mechanisms can be used to restrict relative rotation between the connecting beam and the hanging beam.
[0006] Based on the above technical features, in the present utility model, on the traveling jig with a motor failure, multiple fixing brackets are used to fix the hanging beam and the connecting beam, restricting relative rotation between the hanging beam and the connecting beam. When an operator uses the fixed-type traveling jig to hoist a steel billet, the operator directly operates the traveling jig to clamp, move, and open the steel billet, and move the steel billet to a designated position or vehicle stacking, thus avoiding the situation that the connecting beam at the lower part and the hanging beam at the upper part deflect due to the damage of the motor, large weight and large inertia of the hoisted steel billet, and further causing the steel billet to be stacked unevenly. At the same time, modifying the traveling jig with a motor failure to enable it to continue the hoisting work will not cause waste of equipment and save costs.
[0007] Preferably in this technical solution, each of the fixing brackets includes at least two fixing structures arranged along the first direction, each of the fixing structures is fixedly connected, and each of the fixing structures is formed by fixedly connecting three horizontal plates and two vertical plates into a "day"-shaped frame. The three horizontal plates and the two vertical plates cooperate to form a first limiting space into which the hanging beam extends and a second limiting space into which the connecting beam extends. The first limiting space and the second limiting space are arranged along the second direction. The first limiting spaces in each of the fixing structures cooperate with each other to form the first fixing portion, and the second limiting spaces in each of the fixing structures cooperate with each other to form the second fixing portion.
[0008] Based on the above technical features, the fixing structure is formed into a "day" - shaped frame by splicing three horizontal plates and two vertical plates. Multiple "day" - shaped frames arranged along the first direction are fixedly connected to form a fixing rack. The formed fixing rack has a simple structure, and at the same time, it can firmly fix the hanging beam and the connecting beam, preventing dislocation and relative rotation, thereby making the stacking of steel billets more orderly and increasing the stacking height of steel billets.
[0009] Preferably in this technical solution, when the fixing rack is in the locked state, the axis of the connecting beam is parallel to the first direction, and the axes of the connecting beam and the hanging beam are in the same plane parallel to the second direction.
[0010] Preferably in this technical solution, along the third direction, the width dimensions of the connecting beam and the hanging beam are the same. In each fixing structure, the top horizontal plate and the bottom horizontal plate are arranged along the second direction and both extend along the third direction. Among them, the top horizontal plate contacts the top surface of the hanging beam, the middle horizontal plate extends along the third direction and extends into the space between the hanging beam and the connecting beam, the bottom horizontal plate contacts the bottom surface of the connecting beam, the two vertical plates are arranged along the third direction and both extend along the second direction. At the same time, both vertical plates contact the side surfaces of the connecting beam and the hanging beam. The third direction is perpendicular to the first direction and the second direction respectively.
[0011] Preferably in this technical solution, both ends of the three horizontal plates are welded to the two vertical plates respectively.
[0012] Preferably in this technical solution, in the fixing rack, between every two adjacent fixing structures, they are fixedly connected by multiple connecting plates. The multiple connecting plates are all arranged between the two vertical plates of adjacent two fixing structures, and both ends of the connecting plates are welded to the two vertical plates.
[0013] Preferably in this technical solution, the number of the fixing racks is two, and the two fixing racks are respectively clamped and limited at both ends of the hanging beam and the connecting beam.
[0014] Preferably in this technical solution, the top mechanism includes two lifting lugs. The two lifting lugs are respectively arranged at both ends of the top surface of the hanging beam. The lifting lug includes two lifting plates and a connecting shaft. Among them, the two lifting plates are arranged along the first direction, and the plate surfaces of the two lifting plates are perpendicular to the first direction; the connecting shaft extends along the first direction, and both ends of the connecting shaft are fixedly connected to the two lifting plates respectively.
[0015] Preferably in this technical solution, the two fixing racks are respectively located between the two lifting plates. The fixing rack includes two said fixing structures, and the two fixing structures respectively contact the plate surfaces of the two lifting plates.
[0016] Based on the above technical features, the two fixing structures are in contact with the surfaces of the two hanging plates respectively, which further restricts the movement of the fixing frame along the axis in the first direction, making the fixing frame durable and requiring virtually no maintenance.

Therefore, they should not be construed as limitations on this utility model.
[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.
[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.
[0025] Before understanding this utility model, it is important to understand that when the motor in the fixed crane clamp fails, it is not necessary to remove the motor and its wiring. Only multiple fixing brackets 5 are needed to secure the lifting beam 11 and connecting beam 3 to the crane clamp, thus eliminating the need to remove the motor 21 and wiring, making maintenance more convenient. When using the fixed crane clamp of this utility model, it is only necessary to directly operate the crane clamp to clamp, move, and open the billet, moving the billet to a designated position or stacking it on a vehicle. This correspondingly reduces the power consumption of the motor 21 indirectly controlling the rotation and position adjustment of the billet.
[0026] like Figures 1 to 3 As shown, this utility model provides a technical solution: a fixed crane clamp, including a top mechanism 1, a rotary drive mechanism 2, a connecting beam 3, a clamping mechanism 4, and a fixing frame 5.
[0027] Specifically, such as Figure 1 and Figure 2 As shown, the top mechanism 1 includes a lifting beam 11 and a lifting lug 12. The lifting beam 11 extends along a first direction, and the lifting lug 12 is fixed to the top of the lifting beam 11. The lifting lug 12 is used to connect to the top crane mechanism, which can control the movement of the crane clamp.
[0028] Furthermore, in this embodiment of the present invention, the top mechanism 1 includes two lifting lugs 12, which are respectively disposed on the top surfaces of both ends of the lifting beam 11. Each lifting lug 12 includes two lifting plates 12A and a connecting shaft 12B. The two lifting plates 12A are arranged along a first direction (i.e., the extension direction of the lifting beam 11), and the surfaces of both lifting plates 12A are perpendicular to the first direction. The connecting shaft 12B extends along the first direction, and its two ends are respectively fixed to the two lifting plates 12A. The crane clamp is connected to the top crane mechanism through the connecting shaft 12B. The lifting plates 12A are welded to the top surface of the lifting beam 11, and the structural strength of the lifting plates 12A is increased by reinforcing ribs between the lifting plates 12A and the lifting beam 11.
[0029] Specifically, such as Figure 1 and Figure 2 As shown, the rotary drive mechanism 2 includes a motor 21 and a transmission gear 22. The motor 21 is fixedly connected to the lifting beam 11. The output end of the motor 21 is connected to the transmission gear 22. The transmission gear 22 is located between the lifting beam 11 and the connecting beam 3. One end of the transmission gear 22 is rotatably connected to the lifting beam 11, and the other end is fixedly connected to the connecting beam 3. The motor 21 can drive and control the lifting beam 11 and the connecting beam 3 to rotate relative to each other about a second direction as an axis. The second direction is the lifting and lowering direction of the crane clamp and is perpendicular to the first direction.
[0030] Further, when the motor 21 does not fail, a pinion is coaxially connected to the output shaft of the motor 21. The pinion is meshed with the transmission gear 22. After the motor 21 starts, the transmission gear 22 is driven to rotate by the pinion, and the transmission gear 22 rotates to drive the connecting beam 3 and the clamping mechanism 4 to rotate, thereby realizing the rotary lifting of the billet to be lifted within a range of 360°. After the motor 21 fails, the traveling fixture cannot control the rotary lifting of the billet to be lifted. Moreover, when lifting the billet, due to the large weight and inertia of the billet, it is inevitable that the pinion and the transmission gear 22 will deflect, resulting in the deflection of the lifted billet and the uneven stacking of the billet. If stacked neatly, up to 20 billets can be stacked, while in the case of uneven stacking, generally only about 10 billets can be stacked, and there is a risk of the billets falling down.
[0031] Specifically, as Figure 1 and Figure 2 shown, the clamping mechanism 4 is installed at the bottom of the connecting beam 3 and is used to clamp and open the billet to be lifted.
[0032] As Figures 1 to 3 shown, the utility model fixes the suspension beam 11 and the connecting beam 3 on the traveling fixture with multiple fixing frames 5 to offset the inertial force generated when lifting the billet and limit the relative rotation between the connecting beam 3 and the suspension beam 11, so as to prevent the lifted billet from deflecting and causing uneven stacking of the billet. Specifically, the fixing frame 5 is divided into a first fixing part and a second fixing part. When the fixing frame 5 is in the locked state, the first fixing part is used to limit the suspension beam 11, and the second fixing part is used to limit the connecting beam 3. The fixing frame 5 forms a limiting mechanism.
[0033] Further, each fixing frame 5 includes at least two fixing structures arranged in the first direction. The fixing structures are fixedly connected, and each fixing structure is formed by fixedly connecting three cross plates and two vertical plates into a "day" - shaped frame. The three cross plates and the two vertical plates cooperate to form a first limiting space into which the suspension beam 11 extends and a second limiting space into which the connecting beam 3 extends. The first limiting space and the second limiting space are arranged in the second direction. The first limiting spaces in each fixing structure cooperate to form the first fixing part, and the second limiting spaces in each fixing structure cooperate to form the second fixing part.
[0034] Still further, as Figures 1 to 3As shown, when the fixing frame 5 is in the locked state, the axis of the connecting beam 3 is parallel to the first direction, and the axes of the connecting beam 3 and the hanging beam 11 are in the same plane parallel to the second direction. In the third direction (i.e., the width direction of the connecting beam 3 in the present utility model), the width dimensions of the connecting beam 3 and the hanging beam 11 are the same. In each fixing structure, the top cross plate and the bottom cross plate are arranged along the second direction and both extend along the third direction. Among them, the top cross plate contacts the top surface of the hanging beam 11, the middle cross plate extends along the third direction and extends into the space between the hanging beam 11 and the connecting beam 3, the bottom cross plate contacts the bottom surface of the connecting beam 3, the two vertical plates are arranged along the third direction and both extend along the second direction. At the same time, the two vertical plates both contact the side surfaces of the connecting beam 3 and the hanging beam 11. The third direction is perpendicular to the first direction and the second direction respectively.
[0035] In the embodiment of the present utility model, the three cross plates and the two vertical plates are made of steel plates with a thickness of 22 mm - 25 mm. The two ends of the three cross plates are respectively welded to the two vertical plates. The fixing structure is formed by splicing the three cross plates and the two vertical plates into a "day" - shaped frame. Multiple "day" - shaped frames arranged along the first direction are fixedly connected to form the fixing frame 5. The formed fixing frame 5 has a simple structure and is easy to obtain materials. At the same time, it can firmly fix the hanging beam 11 and the connecting beam 3, preventing misalignment and relative rotation, thereby making the stacking of steel billets more orderly and increasing the stacking height of steel billets.
[0036] As Figures 1 to 3 shown, in the fixing frame 5, between every two adjacent fixing structures, they are fixedly connected by multiple connecting plates. The multiple connecting plates are all arranged between the two vertical plates of the adjacent two fixing structures, and the two ends of the connecting plates are welded to the two vertical plates.
[0037] In the embodiment of the present utility model, as Figures 1 to 3 shown, the number of the fixing frames 5 is two. The two fixing frames 5 are respectively clamped and limited at both ends of the hanging beam 11 and the connecting beam 3. Specifically, the two fixing frames 5 are respectively located between two hanging plates 12A. The fixing frame 5 includes two fixing structures, and the two fixing structures respectively contact the plate surfaces of the two hanging plates 12A. The two fixing structures respectively contact the plate surfaces of the two hanging plates 12A, further restricting the axial movement of the fixing frame 5 in the first direction, thereby making the fixing frame 5 durable and basically not requiring maintenance. <000009
