Description

Technical Field

[0001] The utility model relates to the field of steel rolling processing equipment, in particular to a pulling mechanism for hot-rolled medium plates. Background Technique

[0002] In the production process of coiled plates, medium plates are inevitably generated. Since the process of generating medium plates from coiled plates exists in a high-temperature environment, it is relatively dangerous to take them out manually. At this time, a pulling mechanism is required to pull out the medium plates.

[0003] When pulling the medium plate, the head of the medium plate pulling mechanism needs to pass through the bottom of the medium plate to the other side, and only after the hook head is lifted can the pulling machine be controlled to start pulling the medium plate back onto the waste billet roller table. Due to the fact that the steel head of the existing pulling mechanism cannot be automatically lifted and needs to be lifted one by one manually, there are not only safety hazards but also relatively low efficiency.

[0004] Therefore, it is very necessary to develop a pulling mechanism for hot-rolled medium plates. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is aimed at the deficiencies of the above-mentioned prior art, and provides a pulling mechanism for hot-rolled medium plates. By welding a counterweight block at the bottom of the hook head of the pulling machine, the hook head of the pulling machine is kept in a natural drooping state with the counterweight block facing downwards in the initial state. Without additional power, the top end of the hook head of the pulling machine can be automatically lifted. When feeding the pulling mechanism, the sliding inclined surface of the hook head of the pulling machine slides into contact with the bottom wall of the medium plate. The hook head of the pulling machine can be twisted without an additional power source, so that it passes through the bottom of the medium plate and is sent to the other end of the medium plate. Under the action of the gravity of the counterweight block, the hook head of the pulling machine is twisted to pull out the medium plate, so as to solve the technical problems proposed in the background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A pulling mechanism for hot-rolled medium plates includes a pulling frame, the pulling frame is arranged in a U shape, a shaft rod is arranged between the two side walls at the top end of the pulling frame, a hook head of the pulling machine is rotatably connected to the outside of the shaft rod, a limiting baffle is fixedly installed between the two side walls of the pulling frame, and a traction part is arranged at the bottom of the pulling frame for feeding and returning the pulling frame and the hook head of the pulling machine. The feeding and returning processes respectively correspond to the feeding and pushing steel states and the returning and pulling steel states of the pulling mechanism;

[0008] A counterweight block is welded to one end of the hook head of the pulling machine. The end of the hook head of the pulling machine away from the counterweight block abuts against the top of the limiting baffle in the feeding and pushing steel state, and the counterweight block abuts against the side wall of the limiting baffle in the returning and pulling steel state. The rotation angle of the hook head of the pulling machine adjusted between the feeding and pushing steel state and the returning and pulling steel state is set to 90°.

After the sliding inclined surface of the hook head of the steel drawing machine slides into contact with the middle plate, it passes through its bottom, and the hook head of the steel drawing machine is twisted under the action of the gravity of the counterweight block until the material drawing fitting surface contacts the side wall of the middle plate.

[0017] Preferably, the corners of the counterweight are arranged in an arc shape.

[0018] The utility model has the following beneficial effects:

The end of the counterweight block abuts against the side wall of the limit baffle, so that the hook head of the steel drawing machine can bear the load and pull out the middle plate. It is convenient and labor-saving, highly safe, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific preferred embodiments.

[0030] In the description of the present invention, it should be understood that the terms "left side," "right side," "upper," "lower," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Terms such as "first" and "second" do not indicate the importance of a component and therefore should not be construed as limiting the present invention. The specific dimensions used in this embodiment are intended solely to illustrate the technical solution and do not limit the scope of protection of the present invention.

[0031] like Figure 1-7As shown in the figure, a drawing mechanism for hot-rolled medium plate includes a drawing frame 1. The drawing frame 1 is set in a U shape. There is a shaft rod 2 between the two side walls at the top of the drawing frame 1. A drawing hook head 3 is rotatably connected to the outside of the shaft rod 2. A limiting baffle 4 is fixedly installed between the two side walls of the drawing frame 1. A traction part is arranged at the bottom of the drawing frame 1 for feeding and returning the drawing frame 1 and the drawing hook head 3. The feeding and returning processes respectively correspond to the feeding and pushing state and the returning and drawing state of the drawing mechanism.

[0032] One end of the drawing hook head 3 is welded with a counterweight 5. In this embodiment, the counterweight 5 is set as a cuboid counterweight with dimensions of 10cm * 5cm * 5cm, and its weight is 15KG. When installing the counterweight 5, it is welded at the middle position in the left-right direction and the rear position in the front-back direction of the drawing hook head 3, ensuring that the drawing hook head 3 can be righted by the gravity of the counterweight 5 after passing through the medium plate.

[0033] The end of the drawing hook head 3 far from the counterweight 5 abuts against the top of the limiting baffle 4 in the feeding and pushing state, and the counterweight 5 abuts against the side wall of the limiting baffle 4 in the returning and drawing state. The rotation angle of the drawing hook head 3 adjusted between the feeding and pushing state and the returning and drawing state is set as 90°.

[0034] Specifically, a gap is reserved between the drawing hook head 3 and the inner wall of the drawing frame 1. A torsion spring is sleeved on the outside of the shaft rod 2 at the gap. The two ends of the torsion spring are respectively fixedly connected to the drawing hook head 3 and the drawing frame 1. Through the cooperation of the torsion spring and the counterweight 5, the drawing hook head 3 can return to the initial state, facilitating the switching of the drawing hook head 3 between the feeding and pushing state and the returning and drawing state.

[0035] Specifically, the traction part is one of an electric push rod, a hydraulic cylinder and a cylinder. When selecting a hydraulic cylinder or a cylinder, a hydraulic drive mechanism or a pneumatic drive mechanism is installed in a supporting manner.

[0036] Specifically, a bracket 6 is fixedly connected to the side wall of the drawing frame 1. The traction part is fixed on an external frame, and the output end of the traction part is connected to the bracket 6 for driving the drawing frame 1.

[0037] Specifically, a rail car 7 is arranged in a fitting manner at the bottom of the drawing frame 1, and the rail car 7 and the drawing frame 1 are detachably installed through bolts 8.

[0038] Specifically, a reinforcing cross rib 9 is fixedly connected to the bottom end of the limiting baffle 4. The limiting baffle 4 and the reinforcing cross rib 9 are perpendicularly arranged, and the two side walls of the reinforcing cross rib 9 are welded to the drawing frame 1. The longitudinal section of the side wall of the drawing frame 1 is set as a right triangle, and the distance from the end of the drawing hook head 3 to the shaft rod 2 is greater than the distance from the top of the drawing frame 1 to the shaft rod 2.

[0039] Specifically, the top height of the steel drawing machine hook head 3 is lower than the top height of the steel drawing frame 1 when it is in the state of feeding and pushing steel, and the top height of the steel drawing machine hook head 3 is higher than the top height of the steel drawing frame 1 when it is in the state of returning to pull steel, so that the feeding steel drawing machine hook head 3 can pass through the bottom of the middle plate when it is in the state of feeding and pushing steel.

[0040] Specifically, one side of the top of the steel drawing machine hook head 3 is set as a sliding inclined surface, and the other side of the top of the steel drawing machine hook head 3 is set as a material contact surface. The sliding inclined surface of the steel drawing machine hook head 3 passes through the bottom of the middle plate after sliding contact with the middle plate. The sliding inclined surface has an inclination angle, which is convenient for the steel drawing machine hook head 3 to contact and twist. No additional power source is required, which is convenient and labor-saving. Under the action of the gravity of the counterweight block 5, the steel drawing machine hook head 3 is twisted until the material contact surface contacts the side wall of the middle plate, the output end of the traction part retracts, and the steel drawing mechanism is pulled back. At this time, the end of the counterweight block 5 abuts against the side wall of the limit baffle 4 and cannot be further flipped, so that the steel drawing machine hook head 3 can bear the load, thereby being able to pull out the middle plate.

[0041] When the utility model is in use, the mechanism is installed on one side of the hot rolling production line and is located between two adjacent sections of the conveying mechanism.

[0042] The counterweight 5 is welded at the bottom of the hook head 3 of the steel drawing machine, so that the counterweight 5 is kept in a natural drooping shape facing downward in the initial state of the hook head 3 of the steel drawing machine. At this time, the top of the hook head 3 of the steel drawing machine is automatically lifted. When the steel drawing mechanism pushes the material, the sliding inclined surface of the hook head 3 of the steel drawing machine slides in contact with the bottom wall of the middle plate. The hook head 3 of the steel drawing machine can be twisted without an additional power source, so that it passes through the bottom of the middle plate and is sent to the other end of the middle plate. Under the action of the gravity of the counterweight 5, the hook head 3 of the steel drawing machine is twisted until the material-fitting surface contacts the side wall of the middle plate, the output end of the traction part retracts, and the steel drawing mechanism is pulled back. At this time, the end of the counterweight 5 abuts against the side wall of the limit baffle 4 and cannot be further flipped, so that the hook head 3 of the steel drawing machine can bear the load, thereby being able to pull out the middle plate.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
