Description

Technical Field

[0001] This utility model relates to the technical field of fire-blocking devices for grinding machines, and in particular to an external fire-blocking device for a profile grinding machine. Background Technology

[0002] In industrial production, profile grinding machines are widely used for processing various metal surfaces, especially in grinding railway rails and mechanical parts. These machines use a high-speed rotating grinding wheel to grind the workpiece to achieve the required surface finish and dimensional accuracy. However, during the grinding process, the contact between the grinding wheel and the workpiece generates a large number of sparks and high-temperature particles. These sparks and particles not only threaten the safety of operators but may also cause fires, damaging surrounding equipment and the environment.

[0003] While existing profile grinding machines incorporate certain safety features in their design, some shortcomings remain. For example, many grinding machines lack effective fire-blocking devices during use, or the existing fire-blocking devices are complex in structure, inconvenient to operate, and difficult to install and disassemble quickly. Furthermore, existing fire-blocking devices may loosen due to external forces during use, leading to unreliable fire-blocking effects, and may even disrupt the normal grinding operation due to instability.

[0004] Taking the NGM-6.3 profile grinder as an example, although this model has protective bars on top, these bars primarily support and protect the grinder itself and do not provide effective fire protection. In actual use, operators need to take additional measures to prevent sparks and high-temperature particles from splashing, such as using temporary fire shields or fireproof cloths. However, these temporary measures are not only cumbersome to operate, but also difficult to guarantee the stability and reliability of their fire-blocking effect.

[0005] Furthermore, existing fire barriers present inconveniences in terms of storage and organization. For example, some fire barriers require significant space when not in use, or necessitate additional tools for storage and securing. This not only increases the workload of operators but may also lead to damage or loss of the fire barriers due to improper storage. Utility Model Content

[0006] The purpose of this utility model is to provide an external fire-blocking device for a profile grinding machine to solve the problems mentioned in the background art.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] External fire shield for contour grinder, including

[0009] Positioning block;

[0010] A mounting component is provided above the positioning block and is used to mount the fire-blocking device on the outside of the profile grinder.

[0011] The positioning block has a through-hole on one side wall, a roller is rotatably connected inside the shaft hole, a fireproof blanket is wound around the outer wall of the roller, and one end of the fireproof blanket is fixedly connected to the outer wall of the roller.

[0012] A fixing component is disposed on one side of the positioning block and is used to limit the movement of the roller.

[0013] Preferably, the model of the profile grinding machine is NGM-6.3.

[0014] Preferably, the mounting assembly includes a hanging rod, a screw, and a handle. The upper wall of the hanging rod has a through opening, the upper wall of the positioning block has a first internal threaded slot, the handle is fixedly mounted on the upper end of the screw, and the lower end of the screw passes through the through opening and rotates with the first internal threaded slot.

[0015] Preferably, the fixing component includes a second internal threaded slot formed on one side wall of the positioning block. The second internal threaded slot is connected to the shaft hole. A lead screw is rotatably connected inside the second internal threaded slot. One end of the lead screw passes through the second internal threaded slot and abuts against the outer side of the roller. The other end of the lead screw is fixedly connected to a handle.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This invention achieves convenient installation and stable fixation of the fire-blocking device through the ingenious design of the hanging and fixing components. The hanging rod, screw, and handle in the hanging component work together to securely install the fire-blocking device on the profile grinder, while also facilitating adjustment and disassembly. The lead screw and handle in the fixing component ensure the stability of the roller during use, preventing the fire blanket from accidentally loosening or unfolding, thus guaranteeing the reliability and stability of the fire-blocking effect. This design not only improves the safety of grinding operations but also meets the stringent safety and environmental protection requirements of modern industrial production, possessing significant practical value.

[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] Example:

[0024] Please see Figures 1-3 As shown, this utility model is an external fire-blocking device for a profile grinding machine, including a positioning block 1;

[0025] A mounting component is provided above the positioning block 1 and is used to mount the fire-blocking device on the outside of the profile grinder.

[0026] The positioning block 1 has a shaft hole 12 through one side wall, a roller 2 is rotatably connected inside the shaft hole 12, a fireproof blanket 3 is wound around the outer wall of the roller 2, and one end of the fireproof blanket 3 is fixedly connected to the outer wall of the roller 2.

[0027] A fixing component is disposed on one side of the positioning block 1 and is used to limit the position of the roller 2.

[0028] As can be seen from the above, the fireproof device is hung on the outside of the profile grinder by the mounting component. When the fireproof blanket 3 is needed, the roller 2 can be rotated to unfold the fireproof blanket 3 from the roller 2 and cover the grinding area, effectively blocking the sparks and high-temperature particles generated during the grinding process. When it is not needed, the fireproof blanket 3 can be rewound back to the roller 2 for easy storage and to keep the device clean.

[0029] By installing the fire blanket 3, sparks and high-temperature particles generated during the grinding process are effectively blocked, reducing the risk of fire and protecting the safety of operators as well as surrounding equipment and the environment from damage. This design not only improves the safety of grinding operations but also meets the stringent safety and environmental protection requirements of modern industrial production.

[0030] The fixing component is set on one side of the positioning block 1 to limit the roller 2. This design ensures that the roller 2 can remain stable during use and prevents the fire blanket 3 from being accidentally loosened or unfolded due to external force, thereby ensuring the reliability and stability of the fire blocking effect.

[0031] The model of the profile grinding machine is NGM-6.3.

[0032] Specifically, under existing technology, the profile grinding machine of this model has a protective bar on top, and furthermore, the workers can hang the two hanging rods 4 on the outer wall of the protective bar.

[0033] Depend on Figure 1 and Figure 3 It is known that the hanging assembly includes a hanging rod 4, a screw 5 and a handle 6. The upper wall of the hanging rod 4 has a through opening 7, the upper wall of the positioning block 1 has a first internal threaded slot 8, the handle 6 is fixedly set on the upper end of the screw 5, and the lower end of the screw 5 passes through the through opening 7 and rotates with the first internal threaded slot 8.

[0034] As can be seen from the above, the hanging rod 4 is connected to the positioning block 1 through the screw 5. The screw 5 is rotatably engaged with the first internal threaded slot 8 on the positioning block 1. The position and tightness of the hanging rod 4 can be easily adjusted by the handle 6 to ensure that the fireproof device is firmly hung on the grinder.

[0035] Depend on Figure 1 and Figure 3 It is known that the fixing component includes a second internal threaded slot 9 opened on one side wall of the positioning block 1. The second internal threaded slot 9 is connected to the shaft hole 12. A lead screw 10 is rotatably connected inside the second internal threaded slot 9. One end of the lead screw 10 passes through the second internal threaded slot 9 and abuts against the outer side of the roller 2. The other end of the lead screw 10 is fixedly connected to a handle 11.

[0036] As can be seen from the above, by rotating the handle 11, the position of the lead screw 10 can be adjusted so that it abuts against the roller 2, thereby limiting the roller 2. This design ensures that the roller 2 remains stable during use, preventing the fire blanket 3 from accidentally loosening or unfolding due to external forces, thus ensuring the reliability and stability of the fire-blocking effect.
