Description

Technical Field

[0001] The present application belongs to the field of lifting technology, and in particular relates to a lifting tool and a lifting device. Background Art

[0002] The main hook of the overhead crane in the coil storage area of ​​a steel rolling mill is typically equipped with a dedicated coil hoist. This dedicated coil hoist utilizes a retractable C-shaped clamp to secure the horizontally placed hoist, thereby enabling the lifting of coils. Lifting other heavy items, such as a bundle of steel plates, requires manual removal of the dedicated coil hoist, which has been permanently suspended from the main hook. This is laborious and time-consuming, impacting lifting operations throughout the storage area and, consequently, the efficiency of the production line. Therefore, a lifting device is needed that can shorten the preparation time required by existing lifting devices for lifting coils and other items, thereby improving production line efficiency. Utility Model Content

[0003] The present application aims to at least partially resolve the technical problem that the preparation time of a lifting device for lifting steel coils or other heavy objects is too long, resulting in low production line efficiency. To this end, the present application provides a lifting device and a lifting device.

[0004] On the one hand, the embodiment of the present application provides a sling, comprising two oppositely arranged chucks, each of which has a hanging portion on its inner side; a load-bearing member located between the two chucks; two mounting members connected to both ends of the load-bearing member and located between the two chucks, each of which has a hanging hole, and the two hanging portions extend into the hanging holes in a one-to-one correspondence; a hanging ear connected to the load-bearing member, the hanging ear being used to hang and fix a sling for an object to be lifted, the sling being a sling in the prior art, and the sling being used to hang heavy objects so as to be able to lift the heavy objects. Through the above structure, when the staff uses this sling to transport a large bundle of steel plates, the two chucks can be installed by snapping them into the mounting members, and the heavy objects can be fixed by the hanging ears and slings installed on the load-bearing member, thereby completing the lifting. When it is necessary to lift a steel coil, the staff controls the two chucks to extend so as to detach them from the mounting members, thereby achieving the lifting of the steel coil.

[0005] In some embodiments, the load-bearing member is a load-bearing beam, and the cross-section of the load-bearing beam is I-shaped. During the lifting process, the load-bearing member bears the tension of the heavy object. The I-beam structure has excellent bending resistance and can reduce its own weight, thereby increasing the lifting counterweight.

[0006] In some embodiments, the two chucks can move back and forth along the axial direction of the load-bearing beam, and the length of the load-bearing beam is greater than the distance between the two chucks when they are close to each other, and less than the distance between the two chucks when they are far away from each other. When the length of the load-bearing member is greater than the maximum length of the two chucks and the length of the load-bearing member is less than the minimum length of the two chucks, the two chucks cannot be installed on the mounting member. Therefore, it is necessary to control the length of the load-bearing member to be greater than the minimum length of the two chucks and less than the maximum length of the two chucks, so that the two chucks can be extended into the interior of the mounting member, thereby completing the function of fixing the lifting device. Within this length range, the manufacturer can select the length of the load-bearing member within this length range as needed.

[0007] In some embodiments, the load-bearing member is a solid member, and the load-bearing member is an integrally cast member, so that the load-bearing member has sufficient strength to bear the gravity of the heavy object.

[0008] In some embodiments, the mounting member includes a mounting plate, the lower end of the mounting plate is connected to the load-bearing member, the upper end of the mounting plate extends out of the load-bearing member and is provided with a hanging hole, the lower part of the mounting plate is fixed to the load-bearing member by welding, and the cross-sectional area of ​​the lower part of the mounting plate is equal to that of the load-bearing member, so that the mounting plate and the load-bearing member can have more welding area, thereby ensuring the stability of the mounting member and the load-bearing member and meeting the specifications and standards of the sling.

[0009] In some embodiments, the hanging hole is a rectangular hole, and the hanging portion is a rectangular parallelepiped. Through the above structure, the hanging portion can be completely inserted into the rectangular hole, thereby making the installation of the load-bearing component more stable, and the size of the rectangular hole is larger than the size of the hanging portion, and a certain installation space is reserved, usually in the range of 2 to 5 cm, so that the hanging portion can be smoothly installed in the installation hole, thereby reducing the installation difficulty of the utility model and facilitating operation by staff.

[0010] In some embodiments, a rib is welded between the mounting member and the load-bearing member. During the process of suspending a heavy object, the gravity of the heavy object is borne by the top crossbeam of the mounting member and the static friction between the mounting member and the chuck. When the chuck applies a certain pressure to the mounting member, the greater the static friction, the more likely the mounting member will be subjected to external pressure during this process and bend and deform easily. By providing the rib, the bending resistance of the mounting member can be increased, thereby making the present invention more durable.

[0011] In some embodiments, the mounting member is an integrally forged plate, which is integrally cast from high-strength steel to ensure sufficient strength, prevent the mounting member from being damaged by excessive pressure, and thus be more durable.

[0012] In some embodiments, the hanging ear is provided with a self-locking structure, and the hanging ear is welded and fixed on the load-bearing member. The self-locking structure can prevent the sling from slipping, and the welding fixation can prevent the hanging ear from falling, thereby ensuring safety. There are four hanging ears, and the four hanging ears are evenly distributed on both sides of the load-bearing member, which can ensure more uniform suspension.

[0013] On the other hand, an embodiment of the present application provides a lifting device, an overhead crane, the overhead crane is provided with a hook; a telescopic beam, the telescopic beam is installed on the hook, and two clamps are provided at both ends of the telescopic beam; the sling is mounted on the clamp.

[0014] The technical principle of the utility model is to realize the rapid installation of the utility model through the installation piece, and to realize the stable installation of the utility model by utilizing the pressure between the two clamps and the clamping structure between the installation piece and the load-bearing piece;

[0015] By setting up hanging ears and slings, heavy objects such as a bundle of steel plates can be lifted.

[0016] The benefits of this utility model:

[0017] By providing the load-bearing parts and the mounting parts, the utility model can be quickly installed on the two oppositely arranged clamping heads, thereby avoiding the tedious disassembly work in the prior art and improving the production efficiency of the production line;

[0018] By arranging a hanging ear which can cooperate with the sling on the load-bearing member, the lifting of a bundle of steel plates and other heavy objects can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the related art, steel coil slings have the problem of being inconvenient to assemble and disassemble when lifting other heavy objects, resulting in low efficiency. The embodiments of the present application provide a sling and a lifting device that can at least to some extent solve the technical problems of steel coil slings being time-consuming, labor-intensive, and inconvenient to assemble and disassemble when lifting other heavy objects.

[0028] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0029] In the first place, see Figure 1The embodiment of the present application provides a sling, comprising two oppositely arranged chucks 1, each of which has a hanging portion on its inner side; a load-bearing member 2, located between the two chucks 1; two mounting members 4, connected to both ends of the load-bearing member 2 and located between the two chucks 1, each of which has a hanging hole 5, and the two hanging portions extend into the hanging holes 5 in a one-to-one correspondence; a hanging ear 3, connected to the load-bearing member 2, the hanging ear 3 being used to hang and fix a sling 7 for an object to be lifted, the sling 7 being a sling 7 in the prior art, and being used to hang heavy objects so as to lift them. Through the above structure, when the staff uses the sling to lift a large bundle of steel plates, the two chucks 1 can be installed by snapping them into the mounting members 4. The heavy objects can be fixed by the hanging ears 3 and the sling 7 installed on the load-bearing member 2, thereby completing the lifting. When it is necessary to lift a steel coil, the staff controls the two chucks 1 to extend so as to separate from the mounting member 4, thereby achieving the lifting of the steel coil.

[0030] In some embodiments, see Figure 1 The load-bearing member 2 is a load-bearing beam, and the cross-section of the load-bearing beam is I-shaped. During the lifting process, the load-bearing member 2 bears the tension of the heavy object. The I-beam structure has excellent bending resistance and can reduce its own weight, thereby increasing the lifting counterweight.

[0031] In some embodiments, see Figure 1 The two chucks 1 can move back and forth along the axial direction of the load-bearing beam. The length of the load-bearing beam is greater than the distance between the two chucks 1 when they are close to each other, and less than the distance between the two chucks 1 when they are far away from each other. When the length of the load-bearing member 2 is greater than the maximum length of the two chucks 1 and the length of the load-bearing member 2 is less than the minimum length of the two chucks 1, the two chucks 1 cannot be installed on the mounting member 4. Therefore, it is necessary to control the length of the load-bearing member 2 to be greater than the minimum length of the two chucks 1 and less than the maximum length of the two chucks 1, so that the two chucks 1 can be extended into the interior of the mounting member 4, thereby completing the function of fixing the lifting device. Within this length range, the manufacturer can select the length of the load-bearing member 2 within this length range as needed.

[0032] In some embodiments, see Figure 1 The load-bearing member 2 is a solid member and is an integrally cast member, so that the load-bearing member 2 has sufficient strength to withstand the gravity of the heavy object.

[0033] In some embodiments, see Figure 1 、 Figure 2The mounting member 4 includes a mounting plate, the lower end of the mounting plate is connected to the load-bearing member 2, the upper end of the mounting plate extends out of the load-bearing member 2, and is provided with a hanging hole 5. The lower part of the mounting plate is fixed to the load-bearing member 2 by welding. The cross-sectional area of ​​the lower part of the mounting plate is equal to that of the load-bearing member 2, so that the mounting plate and the load-bearing member 2 can have more welding area, thereby ensuring the stability of the mounting member 4 and the load-bearing member 2 and meeting the specifications and standards of the sling.

[0034] In some embodiments, see Figure 1 、 Figure 2 The hanging hole 5 is a rectangular hole, and the hanging part is a rectangular parallelepiped. Through the above structure, the hanging part can be completely inserted into the rectangular hole, so that the installation of the load-bearing member 2 is more stable, and the size of the rectangular hole is larger than the size of the hanging part, and a certain installation space is reserved, usually in the range of 2 to 5 cm, so that the hanging part can be smoothly installed in the installation hole, thereby reducing the installation difficulty of the utility model and facilitating the operation of the staff.

[0035] In some embodiments, see Figure 1 A stiffener 6 is welded between the mounting member 4 and the load-bearing member 2. During the process of suspending heavy objects, the gravity of the heavy object is borne by the top crossbeam of the mounting member 4 and the static friction between the mounting member 4 and the chuck 1. When the chuck 1 applies a certain pressure to the mounting member 4, the greater the static friction, the more likely the mounting member 4 is to be subjected to external pressure during this process, and is prone to bending and deformation. By providing the stiffener 6, the bending resistance of the mounting member 4 can be increased, thereby making the utility model more durable.

[0036] In some embodiments, see Figure 2 The mounting member 4 is an integrally forged plate, which is integrally cast from high-strength steel to ensure sufficient strength, thereby preventing the mounting member 4 from being damaged by excessive pressure, and thus being more durable.

[0037] In some embodiments, see Figure 1 The hanging ear 3 is provided with a self-locking structure, and the hanging ear 3 is welded and fixed on the load-bearing member 2. The self-locking structure can prevent the sling 7 from slipping, and the welding fixation can prevent the hanging ear 3 from falling, thereby ensuring safety. There are four hanging ears 3, and the four hanging ears 3 are evenly distributed on both sides of the load-bearing member 2, which can ensure more uniform suspension.

[0038] On the other hand, an embodiment of the present application provides a lifting device, including: an overhead crane, which is provided with a hook; the sling provided in the above embodiment, a telescopic beam, the telescopic beam is installed on the hook, and two clamps 1 are provided at both ends of the telescopic beam; through the above structure, the utility model can provide power to the entire lifting device through the overhead crane, and can lift the steel coil through the cooperation of the hook, telescopic beam and clamp 1 on the overhead crane. When other heavy objects need to be lifted after the steel coil is lifted and installed, the sling can be installed by controlling the distance between the clamps 1. After the installation is stable, the lifting of the heavy object can be completed. During the whole process, the telescopic beam and the clamp 1 are often removed in technology.
