Description

Technical Field

[0001] This utility model relates to the field of finished plastic products, specifically a movable tunnel fan plastic support. Background Technology

[0002] Mobile tunnel ventilation fans are mobile devices specifically designed for tunnel ventilation scenarios. They are mainly used for local ventilation during tunnel construction and operation. They can be flexibly adjusted in installation position to quickly respond to the ventilation needs of different areas, effectively improve air quality, remove harmful gases and smoke, and ensure personnel safety and comfort. During tunnel construction, these fans can be flexibly deployed in the construction area to provide fresh air for workers while removing harmful gases and dust, ensuring a safe and healthy construction environment. Plastic brackets are support structures made of plastic materials, typically used to fix, support, or suspend various equipment, devices, or items. They have advantages such as being lightweight, corrosion-resistant, and low-cost, and are widely used in industries, construction, and home furnishings. However, due to the relatively low strength and durability of plastics, their application scenarios are usually limited, and they are more suitable for occasions with low load requirements or where lightweight and corrosion-resistant properties are needed. Because of its relatively light weight, plastic supports cannot provide sufficient fixing strength when installed on the tunnel wall like metal supports. They are prone to loosening or displacement during installation or subsequent use. Especially when the fan is running, the fan itself will generate vibrations, which will be transmitted to the support. This will cause the connection between the fan and the support to gradually wear down due to repeated friction and impact. Over time, this wear will make the connection loose, which will affect the stability of the fan during operation and may even cause safety hazards. Therefore, a movable plastic support for tunnel fans is proposed to address the above problems. Utility Model Content

[0017] As a further implementation of this solution, the fixing component 2 includes a plastic sleeve 21, with an aluminum alloy strip 22 fixedly connected to the inner side of the plastic sleeve 21. The plastic sleeve 21 is fitted onto the outer side of the fan body 1, with the lower end of the plastic sleeve 21 inserted into the inner side of the receiving groove 32. The outer side of the plastic sleeve 21 is in contact with the inner side of the first rubber sealing ring 33. The bottom end of the fan body 1 is in contact with the top end of the plastic platform 31. The front and rear ends of the fan body 1 are in contact with the protrusions 6. Through the above arrangement, the aluminum alloy strip 22 improves the overall strength of the fixing component 2, thereby improving the safety of fixing the fan body 1. At the same time, the plastic sleeve 21 and the aluminum alloy strip 22 are fitted onto the outside of the fan body 1 and then fixed inside the plastic platform 31. The protrusions 6 limit the front and rear ends of the fan body 1, thereby achieving the effect of fixing the fan body 1. As a further implementation of this solution, the receiving groove 32, the second folded groove 38, and the second threaded hole 39 are connected, and the receiving groove 32, the connecting hole 35, the first folded groove 36, and the first threaded hole 37 are connected. The diameter of the second threaded hole 39 is twice the diameter of the second folded groove 38. The threaded rod 52 is spirally fitted inside both the first threaded hole 37 and the first threaded hole 39. The upper ends of the second threaded hole 39 and the first threaded hole 37 are fitted with the third rubber sealing ring 53. Through the above settings, the hydraulic oil can be flexibly filled and discharged, which facilitates the fixing and disassembly of the fixed component 2, while ensuring the sealing and stability of the device. As a further implementation of this solution, the first rubber sealing ring 33 is located at the upper end of the receiving groove 32, the silicone duckbill valve 34 is located between the second folded groove 38 and the first folded groove 36 near the receiving groove 32, and the connecting hole 35 is located at the lower end of the plastic platform 31. Through the above arrangement, the unidirectional flow and sealing of hydraulic oil can be effectively realized, thereby preventing the plastic sleeve 21 from coming out of the receiving groove 32 and ensuring the reliability of the fan operation. As a further implementation of this solution, the pull rod 42 slides inside the connecting hole 35, and a gap is provided between the pull rod 42 and the connecting hole 35. The lower end of the spring 45 is fixedly connected to the inner side of the receiving groove 32, and the outer side of the second rubber sealing ring 44 is in contact with the inner side of the receiving groove 32. With the above settings, the operating component 4 provides the power for the hydraulic oil to flow downward, and at the same time, by pushing the pull handle 41 upward, space can be provided for the column block 43 to move downward, and the hydraulic oil at the upper end of the column block 43 can be discharged. As a further implementation of this solution, the plastic support platform assembly 7 includes a plastic support shell 71, with an internal aluminum alloy plate 72 fixedly connected to the inside of the plastic support shell 71. The top ends of both the plastic support shell 71 and the internal aluminum alloy plate 72 are fixedly connected to the bottom end of the plastic platform 31. Through the above arrangement, additional support and stability are provided for the device, further improving the safety and reliability of the device.

[0018] Workflow: To fix the fan body 1, the fan body 1 is hoisted and placed on the upper end of the plastic platform 31, positioned between multiple protrusions 6, aligning the lower foot of the fan body 1 with the protrusions 6. Pushing the handle 41 upwards moves the handle 41, causing the pull rod 42 and the column block 43 to move upwards. When the top of the handle 41 is in contact with the lower end of the connecting hole 35, the top of the column block 43 is positioned near the lower end of the first folded groove 36 of the receiving groove 32. The column block 43 then causes the spring 45 to spring back. Under the elastic tension of spring 45, the column block 43 can be kept moving downwards due to deformation. Then, the sealing assembly 5 is installed inside the first threaded hole 37 and the second threaded hole 39 respectively. By inserting a screwdriver into the flat groove 54, the end plate 51 and the threaded rod 52 are rotated, so that the threaded rod 52 spirally fits against the inside of the first threaded hole 37 or the inside of the second threaded hole 39, until the top of the third rubber sealing ring 53 is tightly against the upper end of the first threaded hole 37, thereby achieving sealing of the first folded groove 36 and the second threaded hole 39. The two-fold groove 38 serves as a sealing element. Hydraulic oil is injected into the receiving groove 32 using a syringe, causing the silicone duckbill valve 34 to deform. Through the deformation of the silicone duckbill valve 34, hydraulic oil is injected between the column block 43 and the silicone duckbill valve 34 until hydraulic oil is stored inside the first fold groove 36 and the second fold groove 38. After the hydraulic oil is filled, the lower end of the plastic sleeve 21 is inserted into the receiving groove 32. With the pull handle 41, it is moved downwards, allowing the lower end of the plastic sleeve 21 to enter the receiving groove 32. The outer side of the plastic sleeve 21 is in contact with the inner side of the first rubber sealing ring 33. At this time, the pull handle 41 is released, allowing two people to operate on both ends of the same plastic sleeve 21 simultaneously. The plastic sleeve 21 is tightly attached to the outer side of the fan body 1. After the multiple fixing components 2 are installed, the multiple protrusions 6 at the front and rear ends limit the fan body 1, preventing the fan body 1 from moving back and forth. The fan body 1 is fixed by the limiting of the fixing components 2. When the blower body 1 is in use, friction occurs between the blower body 1 and the plastic sleeve 21, causing wear at the contact points. This creates a gap between the plastic sleeve 21 and the blower body 1. During the process of eliminating this gap, the spring 45 moves the column block 43 downwards. Under the sealing effect of the second rubber sealing ring 44 between the column block 43 and the plastic platform 31, the hydraulic oil at the upper end of the silicone duckbill valve 34 enters the lower end of the silicone duckbill valve 34 through the valve's interior. Under negative pressure... When in use, the plastic housing 21 will move downwards. The first rubber sealing ring 33 acts as a seal between the plastic platform 31 and the plastic housing 21. The silicone duckbill valve 34 acts as a one-way flow valve for hydraulic oil, which prevents the plastic housing 21 from moving upwards. The operating component 4 continuously draws in hydraulic oil, keeping the plastic housing 21 moving downwards. This ensures that the plastic housing 21 and the blower body 1 are always in close contact, thus preventing gaps caused by wear of the plastic housing 21 from affecting the stability of the blower body 1. When removing the fixed component 2, the sealing component 5 near the corresponding fixed component 2 is removed. At this time, the first folded groove 36 and the second folded groove 38 are connected to the receiving groove 32, so that the hydraulic oil can be discharged. At the same time, the receiving groove 32 near the upper end of the silicone duckbill valve 34 is connected to the second folded groove 38 and the second threaded hole 39, so that the fixed component 2 can be directly removed, thereby achieving the disassembly effect and providing feasibility for fixing the fan body 1 again. Based on the above principles, after the device fixes the fan body 1, it can prevent the gap caused by the wear of the plastic sleeve 21 due to the vibration generated when the fan body 1 is working from affecting the stability of fixing the fan body 1. The device can continuously adjust the position of the fixing component 2, thereby preventing the connection from becoming loose, ensuring that the stable operation of the fan body 1 is not affected, and improving the safety of the device.
