Description

Technical Field

[0001] This utility model relates to the field of steel coil clamp technology, specifically a steel coil clamp with a pressure plate. Background Technology

[0002] Steel coil clamps are specialized tooling fixtures used in conjunction with loading and unloading equipment such as cranes and forklifts. Their core function is to safely and efficiently complete operations such as lifting, handling, and stacking steel coils or cylindrical items. They are widely used in steel plants, steel warehouses, ports, automobile manufacturing, and other scenarios involving the circulation of steel coils. Steel coil clamps are also commonly used for handling when transporting or dumping molten aluminum in containers.

[0003] However, the old-style steel coil clamp has obvious compatibility defects and safety hazards when used to hold containers containing molten aluminum. On the one hand, due to the different distances to the destinations of the molten aluminum, the temperature of the molten aluminum drops rapidly during transportation, which can easily lead to premature solidification and affect subsequent use. Moreover, the clamping stability of the old-style steel coil clamp is insufficient, and the molten aluminum is prone to overflow during handling and bumping, which not only wastes materials but also poses operational risks such as burns due to the high temperature of the molten aluminum. On the other hand, the old-style steel coil clamp lacks a tilting control structure, making it difficult to adjust the tilting speed during the molten aluminum pouring operation. This results in unstable control of the molten aluminum flow, which can easily lead to problems such as sudden large flow splashing or low flow and low efficiency. This seriously affects the continuity and safety of subsequent pouring, processing and other processes, and brings many inconveniences to actual production operations. Utility Model Content

[0005] In view of the problems existing in the above and / or existing steel coil clamps, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a steel coil clamp with a pressure plate.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A steel coil clamp with a pressure plate includes: a base frame and an aluminum liquid container; a support base is connected to the rear outer wall of the base frame; a plurality of hydraulic cylinders are fixedly connected inside the support bases; the output ends of the plurality of hydraulic cylinders are connected to a clamping arm assembly for clamping the aluminum liquid container; mounting bases and support frames are also fixedly installed on the rear outer wall of the base frame; a plurality of hydraulic cylinders are rotatably connected to the inner walls of the mounting bases; and a pressure plate assembly for sealing the top of the aluminum liquid container is rotatably connected to the output ends of the plurality of hydraulic cylinders.

[0008] As a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, the clamping arm assembly includes a connecting seat connected to an output end of the hydraulic cylinder, and the outer wall of the connecting seat has a through-hole that matches the diameter of the hydraulic cylinder.

[0009] In a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, a clamping arm is connected to the side wall of the connecting seat, a clamping plate is installed on the outer wall of the clamping arm, and a rubber block is installed on the outer wall of the clamping plate.

[0010] In a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, the pressure plate assembly includes a crank rod rotatably connected to the output end of the hydraulic cylinder, and mounting brackets are connected to the ends of the plurality of support frames.

[0011] As a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, the mounting frame is fixedly connected to the outer circumference of the mounting frame with connecting rods, and the ends of the multiple connecting rods are rotatably connected to the outer wall of the support frame.

[0012] As a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, the bottom of the mounting frame is fixedly connected to an insulation board, and the top of the insulation board is connected to a mounting shell one and a mounting shell two.

[0013] As a preferred embodiment of the steel coil clamp with pressure plate described in this utility model, the outer wall of the mounting shell is provided with a cover plate, the top of the inner cavity of the mounting shell is connected with a spring, the ends of the multiple springs are connected with movable plates, the bottom of the movable plates are connected with connecting columns, the ends of the connecting columns are connected with sealing plugs, and the top of the mounting shell is threaded with a threaded rod.

The threaded bolt will limit the rising height of the movable plate, indirectly controlling the opening range of the sealing plug, and finally achieving stable control of the aluminum liquid pouring flow. Compared with the existing steel coil clamp, this device not only solves the problems of rapid cooling and easy overflow of aluminum liquid, but also controls the flow rate, significantly improving its practicality and safety.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] This utility model provides a steel coil clamp with a pressure plate, including a base frame 100 and an aluminum liquid container 400. A support seat 110 is connected to the rear outer wall of the base frame 100. A hydraulic cylinder 120 is fixedly connected inside the support seat 110. The output end of the hydraulic cylinder 120 is connected to a clamping arm assembly for clamping the aluminum liquid container 400. A mounting seat 200 and a support frame 220 are also fixedly installed on the rear outer wall of the base frame 100. A hydraulic cylinder 210 is rotatably connected to the inner wall of the mounting seat 200. The output end of the hydraulic cylinder 210 is rotatably connected to a pressure plate assembly for sealing the top of the aluminum liquid container 400.

[0023] Specifically, the clamping arm assembly includes a connecting seat 130 connected to the output end of the hydraulic cylinder 120, and the outer wall of the connecting seat 130 has a through-hole 131 that matches the diameter of the hydraulic cylinder 120.

[0024] In some embodiments, the design of the through-hole 131 is mainly to facilitate the lateral movement of the two clamping arm assemblies without causing obstruction or collision.

[0025] Specifically, the side wall of the connecting seat 130 is connected to a clamping arm 140, the outer wall of the clamping arm 140 is fitted with a clamping plate 150, and the outer wall of the clamping plate 150 is fitted with a rubber block 160.

[0026] In some embodiments, the rubber block 160 is preferably made of silicone rubber or fluororubber, but thermal insulation cotton (ceramic fiber cotton or rock wool insulation cotton) may also be used as a substitute.

[0027] Specifically, the pressure plate assembly includes a crank 300 rotatably connected to the output end of the hydraulic cylinder 210, and multiple support frames 220 with mounting brackets 310 connected to their ends.

[0028] In some embodiments, the device can be driven by multiple hydraulic cylinders 210 to drive the crank 300, thereby lifting or lowering the insulation plate 330.

[0029] Specifically, a connecting rod 320 is fixedly connected to the outer circumference of the mounting frame 310, and the ends of multiple connecting rods 320 are rotatably connected to the outer wall of the support frame 220.

[0030] Specifically, the bottom of the mounting bracket 310 is fixedly connected to an insulation board 330, and the top of the insulation board 330 is connected to a first mounting shell 340 and a second mounting shell 350.

[0031] In some embodiments, the insulation board 330 has a metal exterior and a hollow interior, filled with rock wool insulation to improve its insulation performance.

[0032] Specifically, the outer wall of the mounting shell 340 is provided with a cover plate 341, the top of the inner cavity of the mounting shell 340 is connected with a spring 342, the ends of multiple springs 342 are connected with a movable plate 343, the bottom of the movable plate 343 is connected with a connecting post 344, the end of the connecting post 344 is connected with a sealing plug 345, and the top of the mounting shell 340 is threaded with a threaded rod 346, which facilitates the restriction of the movement space of the movable plate 343.

[0033] Specifically, a counterweight 351 is slidably connected inside the mounting shell 350. An inclined surface is provided on one side of the outer wall of the counterweight 351, and a protrusion is integrally formed on one side of the counterweight 351. The protrusion is located at the bottom of the movable plate 343.

[0034] In some embodiments, a rubber pad adapted to the shape of the counterweight 351 can be added to the bottom of the counterweight 351. (Preferably made of wear-resistant, high-temperature resistant silicone rubber or fluororubber, suitable for the ambient temperature around the aluminum liquid container). The core function of this rubber pad is to provide slight and controllable friction: during the transport of the aluminum liquid container by the steel coil clamp (in a non-tipping state), the friction between the rubber pad and the inner wall of the mounting shell 350, combined with the weight of the counterweight 351 itself, can effectively counteract the inertial force generated by transport bumps or equipment start-up and shutdown, preventing the counterweight 351 from accidentally sliding and pushing against the movable plate 343, thereby preventing the sealing plug. Unexpected rise of 345 caused aluminum liquid leakage, ensuring the sealing and safety during transportation. When the steel coil clamp enters the tilting operation state, as the tilt angle increases, the component force generated by the gravity of the counterweight 351 along the tilting direction will gradually exceed the friction force of the rubber pad. At this time, the counterweight 351 can smoothly slide along the inner wall of the mounting shell 350. Its protrusion and tilting surface can reliably press the movable plate 343 to rise, driving the sealing plug 345 to open to regulate the flow of aluminum liquid. This not only solves the problem of accidental triggering during transportation, but also does not affect the normal flow control action during tilting, further optimizing the practical performance of the device.

[0035] In some embodiments: In some embodiments, the hydraulic cylinders used in the steel coil clamp (including hydraulic cylinder 120 for driving the opening and closing of the clamping arm and hydraulic cylinder 210 for controlling the lifting and lowering of the pressure plate assembly) are all commercially available standardized models. Their structure (such as cylinder body, piston rod, seals) and working principle (using hydraulic oil pressure to drive piston movement to achieve extension and retraction) are known existing technologies in the industrial field and do not require additional innovative design. In actual applications, these hydraulic cylinders only need to be paired with conventional hydraulic oil supply devices (such as hydraulic pumps, oil tanks, pipelines and control valve groups to provide stable pressure hydraulic oil and control the extension and retraction of the hydraulic cylinders) to operate normally. The connection method and control logic of the entire hydraulic drive system are also common technical solutions in the industry. Therefore, there is no need to elaborate here, and it can be directly adapted to existing hydraulic control systems to achieve the function.

[0036] In this embodiment, when the device is in actual use, activating multiple hydraulic cylinders 210 drives the pressure plate assembly to rotate and close, completely sealing the top of the aluminum liquid container 400. This design effectively reduces the contact between the aluminum liquid inside the container and the cold air outside, slows down the rate of temperature drop of the aluminum liquid during transportation, prevents the aluminum liquid from solidifying prematurely, and also prevents the aluminum liquid from splashing out during transportation bumps, completely eliminating the safety risk of aluminum liquid spillage. On the other hand, the device is equipped with a movable plate 343, a sealing plug 345, and a threaded bolt 346 inside the mounting shell 350. Before pouring the aluminum liquid, the threaded bolt 346 can be rotated to preset the maximum movement space of the movable plate 343. When tilting, the counterweight 351 inside the housing 350 will be heavier as the steel coil clamp tilts and pours the material. Under the action of gravity, the counterweight 351 will slide forward. The inclined side wall of the counterweight 351 will push the movable plate 343 upward, thereby driving the sealing plug 345 to move upward and open the drainage channel. The threaded bolt 346 will limit the rising height of the movable plate 343, indirectly controlling the opening range of the sealing plug. Finally, the flow rate of aluminum liquid is stably controlled. Compared with the existing steel coil clamp, this device not only solves the problems of rapid cooling and easy overflow of aluminum liquid, but also controls the flow rate, which significantly improves its practicality and safety.

[0037] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
