Description

Technical Field

[0001] This utility model relates to the field of steel hoisting technology, and in particular to a hoisting device for H-beam steel production. Background Technology

[0002] The production of H-beams requires steel hoisting. Although the structure of the H-beam's flanges and floats increases the stress points during hoisting, the grippers of general hoisting devices only use clamping force to fix the H-beam. Excessive clamping force increases the power burden on the grippers and can cause indentations and deformation of the flanges due to excessive clamping force, affecting the product's appearance and dimensional accuracy. Conversely, when the clamping force is too low, the friction between the H-beam and the grippers decreases, increasing the risk of slippage during hoisting. Furthermore, since general hoisting devices rely solely on the weight of the H-beam to stabilize the friction between the grippers and the H-beam, the swaying of the H-beam during hoisting can cause instantaneous fluctuations in the force on the grippers, reducing hoisting safety. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a hoisting device for H-beam production, which increases the stress points of H-beams, improves the stability of H-beams during hoisting, reduces the negative impact of H-beam swaying during hoisting, and increases the safety of H-beam hoisting.

[0004] This utility model also provides a hoisting device for H-beam production, comprising: a motor-driven gripper, the motor-driven gripper consisting of a housing, a right-angled jaw, and a servo motor transmission mechanism disposed inside the housing; a mounting tube, the mounting tube being fixed to the lower surface of the housing; a cylinder, the cylinder being fixed inside the mounting tube, and the output end of the cylinder being fixedly connected to a plate; and a dust cover, the dust cover being fixed between the plate and the inner wall of the mounting tube. This device provides a downward thrust to the H-beam being gripped and hoisted, improving the stability of the H-beam during hoisting and increasing the safety of the H-beam hoisting operation.

[0005] According to the present invention, a hoisting device for H-beam production includes a pad fixedly connected to the lower end of the right-angle claw, the pad contacting the flange of the H-beam. This reduces the risk of wear on the H-beam.

[0006] According to the present invention, a hoisting device for H-beam steel production includes a side plate on the surface of the mounting pipe, screw holes on the surface of the side plate, and the upper end of the mounting pipe is embedded in the upper surface of the housing. This improves the ease of assembling and disassembling the mounting pipe.

[0007] According to the present invention, a hoisting device for H-beam production includes a right-angle claw that is slidably connected to the housing, and a scraper ring is fixedly connected to the surface of the right-angle claw. This facilitates the cleaning of impurities at the sliding point of the right-angle claw.

[0008] According to the present invention, a hoisting device for H-beam production includes a dust-proof cloth fixedly connected between the right-angle claw and the housing, which covers the sliding part of the right-angle claw, reducing the possibility of impurities entering the housing.

[0009] According to the present invention, a hoisting device for H-beam production includes slots on the left and right sides of the flat plate. When the device is not in use, the two right-angled claws contact the inner walls of the slots, thereby increasing the stability of the claws in their retracted state.

[0010] According to the hoisting device for H-beam production described in this utility model, a protective sleeve is slidably connected to the surface of the mounting pipe, and the side plate on the surface of the mounting pipe is located inside the protective sleeve. This prevents impurities from affecting the side plate.

[0011] According to the hoisting device for H-beam production described in this utility model, the length of the dust cover is greater than the length of the mounting pipe, and the dust cover is in a folded state. This improves the effectiveness of the dust cover.

[0012] Beneficial effects: The hoisting device for H-beam production in this technical solution uses a cylinder to apply a downward thrust to the H-beam, which, combined with the clamping force of the grippers, forms a two-way constraint structure of clamping force and downward pressure. This increases the compactness between the H-beam and the grippers, improves the stability of the H-beam during hoisting, and reduces the risk of center of gravity shift due to swaying during hoisting, thus reducing safety hazards during H-beam hoisting. The installation pipe, which uses snap-fit ​​and bolt fixing, is easy to disassemble and reduce the difficulty of cylinder maintenance. Attached Figure Description

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-5 This utility model discloses a hoisting device for H-beam production, comprising: a motor-driven gripper 1, which consists of a housing 9, a right-angled jaw 10, and a servo motor transmission mechanism disposed inside the housing 9; the motor-driven gripper 1 is a common automatic clamping device in daily life; a mounting tube 6, which is fixed to the lower surface of the housing 9; a cylinder 7, which is fixed inside the mounting tube 6 and is used to apply a downward thrust to the H-beam, and the output end of the cylinder 7 is fixedly connected to a plate 4, which increases the area of ​​the thrust; and a dust cover 5, which is fixed between the plate 4 and the inner wall of the mounting tube 6, the length of the dust cover 5 being greater than the length of the mounting tube 6, and the dust cover 5 being in a folded state to reduce the impact of dust and impurities on the cylinder 7.

[0017] A washer 2 is fixedly connected to the lower end of the right-angle claw 10. The washer 2 contacts the flange of the H-beam. The washer 2 is used to increase the friction between the right-angle claw 10 and the H-beam and to prevent the right-angle claw 10 from wearing the flange of the H-beam.

[0018] The surface of the mounting tube 6 is provided with a side plate, and the surface of the side plate is provided with screw holes. The upper end of the mounting tube 6 is embedded in the upper surface of the housing 9. The presence of the side plate and screw holes of the mounting tube 6 provides the conditions for fixing the mounting tube 6 with bolts, increasing the convenience of assembling and disassembling the mounting tube 6. At the same time, the embedded structure further increases the stability of the mounting tube 6.

[0019] The right-angle claw 10 is slidably connected to the housing 9, and a scraper ring 3 is fixedly connected to the surface of the right-angle claw 10. The scraper ring 3 is used to increase the convenience of cleaning impurities at the sliding part of the right-angle claw 10.

[0020] A dust cover 8 is fixedly connected between the right-angle claw 10 and the housing 9. The dust cover 8 covers the sliding part of the right-angle claw 10 and is used to reduce the entry of impurities into the housing 9.

[0021] The left and right sides of the plate 4 are provided with slots 11. When the device is not in use, the two right-angle claws 10 are in contact with the inner wall of the slots 11 respectively. The slots 11 are used to limit the stability of the right-angle claws 10 when not in use.

[0022] A sheath 12 is slidably connected to the surface of the mounting tube 6. The side plate on the surface of the mounting tube 6 is located inside the sheath 12. The sheath 12 is used to isolate the side plate of the mounting tube 6 from the bolts, reducing the impact of impurities on the ease of disassembly and assembly of the mounting tube 6.

[0023] Working principle: After the right-angle claw 10 approaches the flange of the H-beam, the bent part of the right-angle claw 10 supports the flange. At this time, the output end of the cylinder 7 extends and pushes the plate 4 downwards towards the H-beam until the plate 4 is tightly attached to the upper surface of the H-beam. At this time, the H-beam is subjected to the clamping force and downward pressure on both sides of the flange. During the hoisting process, the right-angle claw 10, which clamps and supports the flange of the H-beam, is subjected to the weight of the H-beam and the downward force applied by the cylinder 7. The downward pressure provided by the cylinder 7 directly increases the compactness between the H-beam and the right-angle claw 10.

[0024] After the hoisting device has been used for a long time, manually pull the protective sleeve 12 down to expose the bolts fixing the mounting pipe 6. At this time, the mounting pipe 6 will be separated from the housing 9. After the mounting pipe 6 is separated, it provides sufficient space for the staff to inspect the cylinder 7, thereby reducing the overall maintenance difficulty of the motor gripper 1.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
