Description

Technical Field

[0001] This utility model relates to the field of round steel finishing feeding technology, and in particular to a round steel finishing feeding platform. Background Technology

[0002] Round steel finishing refers to the subsequent fine processing of round steel that has undergone preliminary processing, in order to improve its surface quality, dimensional accuracy, shape accuracy, etc., so that it can meet higher usage requirements. Due to its own weight, round steel requires the assistance of corresponding equipment when loading and unloading.

[0003] Therefore, in the existing technology of a round steel finishing feeding platform, the publication number is CN215035975U. Under the action of gravity, the steel bar rolls along an arc surface with a specific inclination angle and works perfectly with a specific conveying device. It will not break out of the feeding platform due to excessive speed, nor will it fail to feed normally if the steel is slightly out of round or bent, thus avoiding the need for manual steel handling.

[0004] However, after the round steel on the loading platform is used up, it needs to be replenished. Since one side of the loading platform is significantly higher than the ground, it is necessary to use appropriate equipment to assist in replenishing the round steel on the surface of the loading platform. The additional equipment will inevitably occupy a certain amount of workspace when replenishing the round steel on the loading platform, and the movement of the equipment in the work area will also create safety hazards in the on-site environment. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a round steel finishing and feeding platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a round steel finishing and feeding platform, including a movable frame, a placement plate for placing round steel is hinged to the top edge of one side of the movable frame, two symmetrically arranged winches for pulling the two ends of the round steel are fixedly installed near the top edge of one side of the movable frame, a lifting rail is inserted into the outer side of the movable frame near the middle position, two symmetrically distributed and relatively sliding sliders are embedded and slidably connected to the side of the lifting rail, a swing arm that swings horizontally is hinged to the side of each of the two sliders, a connecting block is hinged to the swing end of the two swing arms, a support arm is hinged to the bottom edge of the connecting block, and the bottom end of the support arm is inserted into the middle position of the side of the movable frame and moves up and down in the vertical direction.

[0007] Preferably, the winch rope passes through the side of the moving frame, and the winch rope inside the winch passes above the lifting rail and is connected to a clamping block. The clamping block has an arc of 190 to 300 degrees and its inner side is inserted into the surface of the round steel.

[0008] Preferably, a motor for driving the screw rotation is fixedly installed on the bottom edge of the movable frame.

[0009] Preferably, an auxiliary arm for sliding connection with the surface of the round steel is fixedly installed on the side of the connecting block away from the movable frame.

[0010] Preferably, a screw is rotatably connected to the middle of one side of the movable frame, and a lifting seat is threadedly connected to the surface of the screw and slidably connected to the side of the movable frame. The side of the lifting seat is hinged to the swing end of the support arm.

[0011] Preferably, two hydraulic rods are symmetrically fixedly installed on the side of the mobile frame, and the telescopic ends of the two hydraulic rods are respectively fixed to the two ends of the bottom edge of the lifting rail.

[0012] Preferably, a horizontally arranged bidirectional lead screw is rotatably connected inside the lifting rail, and the two ends of the bidirectional lead screw are respectively threaded through and connected to the sides of two sliders.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a winch is used to drag the round steel bar to the top of the lifting rail. The relative movement of two sliders inside the lifting rail causes the swing arm to tilt and swing to support the bottom edge of the round steel bar. By driving the lifting rail to rise, the lifting rail can lift the round steel bar supported above to the placement plate. This allows the round steel bar to be automatically replenished without the need for additional equipment, ensuring on-site safety.

[0015] 2. In this utility model, the lifting seat is used so that when the lifting rail is raised or lowered, the screw rotates to make the lifting seat and the lifting rail rise and fall at the same speed. When the lifting rail is stationary, but the connecting block moves horizontally relative to the lifting rail, the screw rotates at another speed to ensure that the lifting seat rises and falls with the horizontal movement of the connecting block. This makes it easier to ensure that the support arm tilts with the movement of the connecting block, thereby ensuring that the support arm always maintains a supporting effect on the bottom edge of the connecting block.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a round steel finishing and loading platform includes a movable frame 2. A loading plate 1 for placing round steel is hinged to the top edge of one side of the movable frame 2. Two symmetrically arranged winches 7 for pulling the two ends of the round steel are fixedly installed near the top edge of one side of the movable frame 2. The winch rope of the winch 7 passes through the side of the movable frame 2. The winch rope in the winch 7 passes above the lifting rail 4 and is connected to a clamping block 6. The arc of the clamping block 6 is 190 to 300 degrees and the inner side of the clamping block 6 is inserted into the surface of the round steel. In use, the round steel is unloaded and piled on one side of the loading platform. The winch 7 is rotated to release the hinge rope to ensure that the clamping block 6 at one end of the hinge rope can be fitted onto the end of the round steel. The two clamping blocks 6 are respectively fitted onto the two ends of the round steel. The clamping blocks 6 are dragged and moved and raised by the rotation of the winch 7 to rewind the hinge rope.

[0024] A lifting rail 4 is inserted near the center of the outer side of the movable frame 2. Two hydraulic rods 3 are symmetrically fixedly installed on the side of the movable frame 2. The telescopic ends of the two hydraulic rods 3 are fixed to the two ends of the bottom edge of the lifting rail 4. When the round steel is dragged onto the lifting rail 4, the extension of the hydraulic rods 3 can raise the lifting rail 4 and drive the round steel to the top of the loading platform. Two symmetrically distributed and relatively sliding sliders 8 are embedded and slidably connected on the side of the lifting rail 4. A horizontally set bidirectional lead screw 5 is rotatably connected inside the lifting rail 4. The two ends of the bidirectional lead screw 5 are threaded through the sides of the two sliders 8. By driving the bidirectional lead screw 5 to rotate by installing a servo motor on the lifting rail 4, the two sliders 8 threadedly connected to it can move relative to each other or towards each other. Both sliders 8 are hinged to the sides of a horizontally swinging arm 9. A connecting block 10 is hinged to the swing end of the swing arm 9. An auxiliary arm 11 for sliding connection with the surface of the round steel is fixedly installed on the side of the connecting block 10 away from the moving frame 2. When the two sliders 8 move relative to or towards each other, the connecting block 10 can move horizontally relative to the lifting rail 4 under the connection action of the swing arm 9. The swing arm 9 can be used to provide auxiliary support for the bottom of the round steel. The auxiliary arm 11 can ensure that the round steel can rise above the swing arm 9 by contacting the surface of the round steel when it rises. A support arm 12 is hinged to the bottom edge of the connecting block 10. The bottom end of the support arm 12 is inserted into the middle of the side of the moving frame 2 and moves vertically. The support arm 12 ensures that the round steel will not bend or deform due to the weight of the round steel when the connecting block 10 is extended and lifting it.

[0025] A screw 13 is rotatably connected to the middle of one side of the movable frame 2. A motor 14 for driving the screw 13 to rotate is fixedly installed on the bottom edge of the movable frame 2. A lifting seat 15 is threadedly connected to the surface of the screw 13 and slidably connected to the side of the movable frame 2. The side of the lifting seat 15 is hinged to the swing end of the support arm 12. When the lifting rail 4 rises and falls, the motor 14 drives the screw 13 to rotate so that the lifting seat 15 and the lifting rail 4 rise and fall at the same speed. When the lifting rail 4 is stationary, but the connecting block 10 moves horizontally relative to the lifting rail 4, the motor 14 drives the screw 13 to rotate at another speed. This ensures that the lifting seat 15 rises and falls with the horizontal movement of the connecting block 10, so that the support arm 12 tilts with the movement of the connecting block 10, thereby ensuring that the support arm 12 always supports the bottom edge of the connecting block 10.

[0026] The working principle is as follows: the loading platform is set between the round steel unloading point and the round steel processing equipment. Two clamps 6 are used to hook the two ends of the round steel. The winch 7 is used to rotate and drag the round steel. When the round steel is dragged to contact the auxiliary arm 11, it rises along the surface of the auxiliary arm 11 to above the lifting rail 4. Then, the bidirectional screw 5 rotates to make the two sliders 8 move relative to each other. Under the connection of the swing arm 9, the connecting block 10 moves away from the lifting rail 4. The swing arm 9 is used to support the bottom of the round steel. Then, the hydraulic rod 3 extends to make the lifting rail 4 drive the round steel to rise above the loading platform. Then, with the loading platform tilted, the round steel rolls down onto the placement plate of the loading platform.

[0027] The wiring diagrams of the hydraulic rod 3, winch 7, and motor 14 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the hydraulic rod 3, winch 7, and motor 14 will not be explained in detail.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
