[0002] Currently, the handling of workpieces in high-temperature equipment is generally done manually using hot tongs. Automated actuators such as motors and cylinders are not used in this process, primarily because the equipment is close to a heat source, and the actuators are prone to failure due to melting of the piping.
[0003] In existing technologies, clamping can also be achieved by adding an actuator such as a cylinder to the far end. These are mostly single-stage articulated structures, which require high cylinder diameter or high motor torque. Utility Model Content
[0004] The purpose of this invention is to provide a force-enhancing structure fire tong for use in high-temperature equipment, which achieves a force-enhancing effect and has low torque requirements, thus effectively reducing costs.
[0005] To solve the above-mentioned technical problems, this utility model provides a force-enhancing structure fire tong for high-temperature equipment, including a movable clamping arm, a fixed clamping arm, a connecting rod, and a telescopic member. The movable clamping arm is hinged to the middle of the fixed clamping arm. The telescopic member is disposed on the fixed clamping arm. The movable end of the telescopic member is connected to the free end of the movable clamping arm through the connecting rod, which is used to control the angle between the clamping ends of the movable clamping arm and the fixed clamping arm and to clamp the high-temperature component. The two ends of the connecting rod are hinged to the movable end of the telescopic member and the free end of the movable clamping arm.
[0006] It also includes a hinged connection part disposed in the middle of the clamp fixing arm. The bottom of the hinged connection part is fixedly connected to the clamp fixing arm, and the top is provided with a hinge hole. The clamp fixing arm is hinged to the clamp movable arm through the hinge hole of the hinged connection part.
[0007] It also includes a connecting rod disposed between the movable end of the telescopic member and the free end of the movable arm of the clamp, the two ends of the connecting rod being hinged to the movable end of the telescopic member and the free end of the movable arm of the clamp.
[0008] The device also includes a slider disposed between the connecting rod and the telescopic member, and a slide rail disposed on the clamp fixing arm. The slider is disposed on the slide rail, which is used to limit the movement direction of the slider. The connecting rod is hinged to the slider, and the telescopic member is snapped or bolted to the slider.
[0009] The slide rail, the slider, and the telescopic component are disposed on the surface of the clamp fixed arm facing the clamp movable arm.

[0016] The high-temperature equipment provided in this embodiment of the utility model uses a force-enhancing structure fire tong. By hinged in the middle of the movable arm and the fixed arm of the clamp, and installing a telescopic component on the fixed arm of the clamp, the movable end of the telescopic component and the free end of the movable arm of the clamp are hinged by a connecting rod. During the extension and retraction of the telescopic component, the angle between the free end of the movable arm of the clamp and the clamping end of the fixed arm of the clamp changes, thereby achieving clamping of the high-temperature component by the clamping end and realizing a force-enhancing effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please refer to Figures 1-3 , Figure 1 A front view structural schematic diagram of an embodiment of the force-enhancing fire tongs used in the high-temperature equipment provided by this utility model; Figure 3 A three-dimensional structural schematic diagram of an embodiment of the force-enhancing fire tongs used in the high-temperature equipment provided by this utility model; Figure 2 A schematic diagram of the stress structure of an embodiment of the force-enhancing fire tongs used in the high-temperature equipment provided by this utility model.
[0024] In one specific embodiment, the force-enhancing fire tongs used in the high-temperature equipment include a movable clamp arm 10, a fixed clamp arm 20, a connecting rod 40, and a telescopic member 30. The movable clamp arm 10 is hinged to the middle of the fixed clamp arm 20. The telescopic member 30 is disposed on the fixed clamp arm 20. The movable end of the telescopic member 30 is connected to the free end of the movable clamp arm 10, which is used to control the angle between the clamping ends of the movable clamp arm 10 and the fixed clamp arm 20 and to clamp the high-temperature component. The two ends of the connecting rod 40 are hinged to the movable end of the telescopic member 30 and the free end of the movable clamp arm 40.
[0025] By hinged at the middle of the movable arm 10 and the fixed arm 20 of the clamp, the telescopic component 30 is installed on the fixed arm 20. The movable end of the telescopic component 30 is hinged to the free end of the movable arm 10 of the clamp through a connecting rod 40. During the extension and retraction of the telescopic component 30, the angle between the free end of the movable arm 10 and the clamping end of the fixed arm 20 is changed, so that the clamping end can clamp the high-temperature component and achieve the force enhancement effect. The requirements for the telescopic component 30 are lower, it is farther away from the fire source, and the impact of high temperature on the execution unit is reduced.
[0026] To further increase the working space and avoid the clamping capacity being poor due to the close spacing between the clamping movable arm 10 and the clamping fixed arm 20, or to avoid directly hinged joints that reduce the structural strength of the clamping mechanism, etc.
[0027] In one embodiment, the force-enhancing fire tongs used in the high-temperature equipment further includes a hinged connection portion disposed in the middle of the clamp fixing arm 20. The bottom of the hinged connection portion is fixedly connected to the clamp fixing arm 20, and a hinge hole is provided at the top. The clamp fixing arm 20 is hinged to the clamp movable arm 10 through the hinge hole of the hinged connection portion.
[0028] By setting a hinge connection in the middle of the clamping fixed arm 20, the clamping movable arm 10 and the clamping fixed arm 20 can be hinged. This allows the hinge to be achieved without compromising the structural strength of either arm, improving the efficiency of the connection. At the same time, the hinge connection allows for height control of the hinge position and control of the clamping angle of the clamping end, improving control efficiency.
[0029] This application does not limit the position of the hinged connection or the connection method with the clamp fixing arm 20. Connection methods including but not limited to snap-fit and welding can be used. It can be installed on the front, on the side, or in other ways.
[0030] By setting a connecting rod 40 between the movable end of the telescopic member 30 and the free end of the movable arm 10 of the clamp, the distance between the telescopic member 30 and the fire source can be increased, improving the safety of use. At the same time, the setting of the connecting rod 40 can limit the movement of the telescopic end of the telescopic member 30 to a small range, improving the safety and reliability of its telescopic process.
[0031] To further improve the efficiency of use, in one embodiment, the force-enhancing structure fire tongs used in the high-temperature equipment also include a slider 50 disposed between the connecting rod 40 and the telescopic member 30 and a slide rail disposed on the clamp fixing arm 20. The slider 50 is disposed on the slide rail, and the slide rail is used to limit the movement direction of the slider 50. The connecting rod 40 is hinged to the slider 50, and the telescopic member 30 is snapped or bolted to the slider 50.
[0032] By providing slide rails on the slider 50 between the connecting rod 40 and the telescopic member 30 and on the clamp fixing arm 20, the slider 50 can be directly driven to push the connecting rod 40 to move. At the same time, the movement of the slider 50 is limited by the slide rail, thereby improving the safety and efficiency of use.
[0033] This application does not impose any limitations on the structure and assembly of the slider 50 and the slide rail.
[0034] Preferably, the slide rail, the slider 50, and the telescopic member 30 are disposed on the surface of the clamp fixing arm 20 facing the clamp movable arm 10.
[0035] By setting the slide rail, slider 50, and telescopic component 30 on the surface of the clamp fixed arm 20 facing the clamp movable arm 10, the linkage 40 can be prevented from being restricted during movement, thereby improving the reliability and freedom of operation and the ease of installation.
[0036] In this application, the transfer of high-temperature components can be performed manually or by using robotic equipment. This application does not limit the structure of the equipment. In one embodiment, the force-enhancing structure fire tongs used by the high-temperature equipment further include a machine connection hole 70 disposed on the side of the clamp fixing arm 20 away from the clamp movable arm 10, and a triangular reinforcing member 80 connecting the machine connection hole 70 and the clamp fixing arm 20. The clamp fixing arm 20 is connected to the robot through the machine connection hole 70, and the triangular reinforcing member 80 is used to strengthen the connection strength between the machine connection hole 70 and the clamp fixing arm 20.
[0037] By setting a connection hole and a triangular reinforcing member 80 at the bottom of the clamp fixing arm 20, it is convenient for personnel and robots to operate the equipment, thereby improving the safety and reliability of use.
[0038] Since the telescopic component 30 may be in a high-temperature environment during use, in order to further reduce the interference of high temperature on it and the interference of other external components on the telescopic component, in one embodiment, the force-enhancing structure fire tongs used by the high-temperature equipment also includes a telescopic protective cover disposed on the clamp fixing arm 20 for protecting the telescopic component 30.
[0039] By setting up a telescopic protective cover, the telescopic component 30 can be freely protected, improving the efficiency, reliability and safety of the telescopic component 30.
[0040] This application does not impose any restrictions on the structure or installation method of the telescopic protective cover.
[0041] In this application, one end of the movable clamp arm 10 and the fixed clamp arm 20 is used for high-temperature clamping. The structure is not limited. In order to improve clamping efficiency and reliability, in one embodiment, the force-enhancing structure fire tongs used by the high-temperature equipment also include a clamping block 60 disposed at the clamping position of the movable clamp arm 10 and the fixed clamp arm 20. The surface of the clamping block 60 is provided with a serrated structure.
[0042] By setting a clamping block 60 at the clamping position of the clamping movable arm 10 and the clamping fixed arm 20, and setting a serrated structure on its surface, the surface roughness is increased, the friction in the clamping block 60 is improved, and the clamping reliability is improved.
[0043] This application does not limit the material or installation method of the clamping block 60, including but not limited to installation by welding.
[0044] In this application, a telescopic component 30 is used to control the angle. Its structure is not limited. The telescopic component 30 can be a telescopic cylinder, a telescopic motor, or other types of telescopic components 30.
[0045] The device in this application reduces the weight of the device while ensuring reliable structural strength, which can reduce the difficulty of clamping. In one embodiment, the force-enhancing structure fire tongs used in the high-temperature device also include at least one weight-reducing hole 90 provided in the movable arm 10 of the clamp.
[0046] By providing at least one weight-reducing hole 90 in the clamping movable arm 10, its overall weight can be effectively reduced, the thrust during the driving process can be reduced, and the driving efficiency can be improved.
[0047] This application does not impose any restrictions on the number, size, shape, or location of the weight reduction holes.
[0048] In one embodiment, the force-enhancing fire tongs used in the high-temperature equipment include a movable clamp arm 10, a fixed clamp arm 20, a connecting rod 40, a slider 50, a cylinder, a hinge shaft, a pin, etc.
[0049] Two parallel and synchronous slides are mounted on the base plate. Connecting rods 40 are mounted on the sliders 50 of both slides, symmetrically arranged. Connecting rods 40 are connected to the side plate hinge holes of the adsorption bracket via hinge shafts. Several electromagnets are mounted on the adsorption bracket. An anti-slip plate is installed on the connecting rod 40 hinge, below the adsorption bracket, to prevent tilting after adsorbing a heavier steel plate. The long connecting rod 40, hinged to the small connecting rod 40, is connected to the connecting rod 40 hinge using a return spring for reset after stamping.
[0050] The movable clamp arm 10 and the fixed clamp arm 20 form the main structure of the tongs via a hinge shaft. The connecting rod 40 and the slider 50 form a force-amplifying structure via hinge shafts. The cylinder body is fixed to the fixed clamp arm 20. The cylinder pushes the slider 50, which slides along the fixed clamp arm 20. Therefore, the fixed clamp arm 20 and the cylinder work together to act on the end of the movable clamp arm via the connecting rod 40. The further the cylinder extends, the closer the connecting rod 40 is to the dead point of the mechanism, creating a force-amplifying effect.
[0051] like Figure 2 As shown, F1 is the cylinder thrust, F2 is the counter-thrust force of the clamp fixing arm 20 on the slider 50, and F_resultant is the resultant force of the two. The resultant force applies force along the connecting rod 40 to the end of the moving arm of the clamp, which is greater than the cylinder's own thrust. When the connecting rod 40 is perpendicular to the sliding direction of the slider 50, it reaches the dead point position, at which point the force is at its maximum. Due to the existence of friction, the clamp will self-lock when it reaches the dead point position, so even if the cylinder stops supplying air, the clamped product can still maintain sufficient clamping force.
[0052] In summary, the force-enhancing fire tongs used in the high-temperature equipment provided by this utility model embodiment hinges the middle of the movable arm and the fixed arm of the clamp, and installs the telescopic component on the fixed arm of the clamp. The movable end of the telescopic component and the free end of the movable arm of the clamp are hinged by a connecting rod, so that during the extension and retraction of the telescopic component, the angle between the free end of the movable arm of the clamp and the clamping end of the fixed arm of the clamp changes, thereby achieving the clamping end to clamp the high-temperature component and achieving the force-enhancing effect. The requirements for the telescopic component are lower, it is farther away from the fire source, and the impact of high temperature on the execution unit is reduced.
[0053] The above provides a detailed description of the force-enhancing structure fire tongs used in the high-temperature equipment provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core idea of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
