Description

Technical Field

[0001] The utility model belongs to the field of lifting equipment, and more specifically, relates to a lifting equipment with an anti-swing steel billet clamp. Background Art

[0002] At present, when setting up an automated insulation pit, the rod and wire raw material workshop needs to be equipped with a special crane, also known as a steel taker, which is mainly used to collect the billets between the roller table, the round-trip platform and the insulation pit. In actual operation, the steel taker generally clamps the billet with a billet clamp, and then moves and lifts the billet clamp with a wire rope to realize the lifting of the billet, taking into account the heavy weight of the billet, equipment cost, equipment installation structure strength and environmental factors.

[0003] However, since the steel wire rope of the steel taker and the billet clamp are softly connected, the billet clamp will swing due to gravity during the lateral movement of the steel taker, whether it is unloaded or loaded, thus affecting the accurate clamping and stacking of the billets. Therefore, in order to reduce or eliminate the swing during production, the lateral movement speed of the steel taker is slow, the precise positioning takes a long time, and the efficiency of automated operation is not high. Especially when the clamp enters and exits the insulation pit, due to the swing, the clamp is very likely to collide with the insulation pit wall and the billet frame of the pit, which will cause damage and fall off of the wall insulation material, and in severe cases, the clamp will fall off the billet.

[0004] For example, the Chinese patent application number is CN202320238299.9, and the patent document with the publication date of February 17, 2023 discloses a billet slow cooling device for buffering hot billets and reducing heat dissipation losses of billets; it includes: a shell structure, a shell insulation layer located in the shell structure, and a refractory partition wall, the partition wall divides the shell structure into at least two independent chambers; the top opening of each independent chamber is used for placing or removing billets; each independent chamber is provided with a cover plate covered at the top opening; a walking track is arranged on the upper part of the independent chamber for the matching steel taking equipment and cover opening equipment to travel; a set of automatic control system, the steel taking equipment and cover opening equipment automatically execute the independent chamber's cover opening, steel taking, cover, and billet delivery to a designated position (or reverse action) according to the instructions of the automatic control system.

[0005] The steel taking equipment of this scheme is provided with a second transverse movement mechanism, a second lifting mechanism arranged on the second transverse movement mechanism and a clamping mechanism arranged on the second lifting mechanism. When the steel taking equipment clamps or stores the steel billet, the clamping mechanism often swings, which affects the efficient operation of the steel taking equipment and the stability of the automatic control system.

[0006] The Chinese patent application number is: CN202322766355.9, and the patent document with the publication date of April 19, 2024 discloses a horizontal electrode clamp, including a vertically arranged mobile frame, the upper end of the mobile frame is equipped with a movable pulley mechanism, the movable pulley mechanism is connected to the lifting mechanism of the crane through a wire rope, and a vertically arranged support plate is fixed to the top of the mobile frame, and a plurality of guide wheel support frames are arranged on the support plate from top to bottom, and a group of guide wheels are arranged on the guide wheel support frames; a guide mechanism is arranged on the left side of the mobile frame, and the guide mechanism includes a horizontally arranged support beam, the support beam is fixed on the beam frame of the crane, and a guide rail for guiding is arranged on the support beam, and each guide wheel is roller-fitted on the guide rail; the lower end of the mobile frame is detachably provided with an electrode clamp for lifting the horizontal electrode.

[0007] In this solution, the cooperation between the guide wheels and the guide rails enables the overall movement of the mobile frame to be precise and without swinging. However, when the clamp clamps the steel billet and moves, the coordination between the guide wheels and the guide rails needs to bear a huge load due to the extremely heavy mass of the clamp and the steel billet itself. Therefore, it is often difficult to ensure stable guiding work, which can easily cause the guide wheels to come off the guide rails. Summary of the invention

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) The utility model is a lifting device with an anti-swing steel billet clamp, in which a pair of guide baffles are installed between a pair of beams. The clamp is located between the pair of guide baffles during movement and lifting. Since the guide baffles can limit the clamp in the horizontal direction, the swing amplitude of the clamp during movement and lifting can be effectively reduced, thereby ensuring the stability of the clamp's lateral movement and lifting action during operation of the lifting device, achieving rapid and accurate clamping and stacking of steel billets, promoting the automated and efficient operation of the lifting device, eliminating the collision of the clamp with the insulation pit wall, the pit body steel billet rack, etc., and reducing the risk of the clamp falling off the billet;

[0024] (2) The utility model is a lifting device with an anti-swing billet clamp. By setting a guide bracket, the movement and lifting of the clamp in the guide baffle can be guided to prevent the clamp from being difficult to accurately rise back into the two guide baffles after it is lowered and separated from the guide baffle to clamp the billet. In addition, the limit of the guide baffle on the clamp that needs to be opened and clamped is transferred to the limit of the guide bracket with a fixed width, which can make the width of the clamp significantly lower than the gap between the two guide baffles, making it convenient for the clamp to clamp and place the billet between the guide baffles. At the same time, the limit of the guide bracket is more accurate, further reducing the swing of the clamp;

[0025] (3) The utility model is a lifting device with an anti-swing billet clamp. A guide wheel is installed on the side of the guide bracket close to the guide baffle, and an inclination is set on the inner side of the bottom of the guide baffle, so that the guide bracket can smoothly enter the guide baffle along the inclination, preventing the guide bracket from being blocked by the lower end of the guide baffle when rising and unable to enter between the two guide baffles.

[0029] Exemplary embodiments of the present invention are described in detail below. Although these exemplary embodiments are described in sufficient detail to enable those skilled in the art to implement the present invention, it should be understood that other embodiments may be implemented and various changes may be made to the present invention without departing from the spirit and scope of the present invention. The more detailed description of the embodiments of the present invention below is not intended to limit the scope of the claimed present invention, but is merely for illustration and does not limit the description of the features and characteristics of the present invention, in order to propose the best way to perform the present invention, and is sufficient to enable those skilled in the art to implement the present invention. Therefore, the scope of the present invention is limited only by the appended claims.

[0030] Example 1

[0031] A lifting device with an anti-swing billet clamp is used for lifting billets in metallurgical production to meet production needs. Its specific structure and technical effects are described in detail below.

[0032] like Figure 1 and Figure 2 As shown, the device includes a frame 1, a pair of beams 2 are symmetrically installed on both sides of the frame 1, and a lifting device 5 for lifting the clamp 4 is installed above the frame 1. Specifically, the lifting device 5 includes a drum 8, a wire rope 9 and an upper crossbeam 10, the drum 8 is fixedly installed on the frame 1, the clamp 4 is installed on the upper crossbeam 10, and the drum 8 is connected to the upper crossbeam 10 through the wire rope 9. In this embodiment, the specific connection structure between the drum 8, the wire rope 9 and the upper crossbeam 10 belongs to the prior art that should be known to those skilled in the art, and will not be elaborated here.

[0033] In order to make the lifting device 5 lift the clamp 4 more labor-saving and convenient, a pulley 11 is provided on the frame 1, and the wire rope 9 is connected to the upper beam 10 through the pulley 11. The specific installation position of the pulley 11 can be the outer side of the beam 2. In this embodiment, there are two groups of pulleys 11, which are respectively arranged at both ends of the upper beam 10.

[0034] However, when the equipment is lifting, grabbing, placing and hoisting the steel billet, due to the flexibility of the wire rope 9 and the limitation of the pulley 11, the clamp 4 usually has a certain degree of swing, which requires the action speed of the clamp 4 to be reduced to reduce the swing, thus affecting the efficiency of hoisting the steel billet. At the same time, the swinging clamp 4 is also easy to collide with the insulation pit wall and the pit body steel billet frame, and in serious cases, there is even a risk of the clamp falling off the billet.

[0035] Therefore, in view of the above problems, the present embodiment provides the following improvements. Specifically, a pair of guide baffles 3 are installed on the inner side of a pair of beams 2, and the clamp 4 is located between the pair of guide baffles 3 during the movement and lifting process. Since the guide baffles 3 can limit the clamp 4 in the horizontal direction, the swing amplitude of the clamp 4 during movement and lifting can be effectively reduced, ensuring the stability of the lateral movement and lifting action of the clamp 4 during the operation of the lifting equipment, realizing the rapid and accurate clamping and stacking of the steel billet, and promoting the automated and efficient operation of the lifting equipment.

[0036] Furthermore, a guide bracket 6 is installed on the upper side of the clamp 4, and the guide bracket 6 is installed on the upper crossbeam 4 and is located between a pair of guide baffles 3, and a guide wheel 7 is installed on the side of the guide bracket 6 close to the guide baffle 3. In this embodiment, the bottom inner side of the guide baffle 3 is provided with an inclination angle, and the guide bracket 6 has at least two, and when the guide bracket 6 is located at the center of the two guide baffles 3, the gap between the guide baffle 3 and the guide wheel 7 is 5-10mm.

[0037] By providing the guide bracket 6, the movement and lifting of the clamp 4 in the guide baffle 3 can be guided, so as to prevent the clamp 3 from being difficult to accurately rise back into the two guide baffles 3 after it is lowered and separated from the guide baffle 6 to clamp the steel billet. In addition, by transferring the limit of the clamp 4 that needs to be opened and clamped by the guide baffle 3 to the limit of the guide bracket 6 with a fixed width, the width of the clamp 4 can be significantly lower than the gap between the two guide baffles 3, which is convenient for the clamp 4 to clamp and place the steel billet between the guide baffles 3. At the same time, the limit of the guide bracket 6 is more accurate, and the swing of the clamp 4 is further reduced.

[0038] The setting of the inner inclination angle of the guide wheel 7 and the bottom of the guide baffle 3 allows the guide bracket 6 to smoothly enter the guide baffle 3 along the inclination, preventing the guide bracket 6 from being blocked by the lower end of the guide baffle 3 when rising and unable to enter between the two guide baffles 3.

[0039] In summary, the lifting equipment with anti-swing billet clamp of this embodiment can reduce the swing phenomenon of the clamp when moving, improve the clamping efficiency, and the effect is relatively stable.
