Description

Technical Field

[0001] This utility model relates to the field of dustproof building construction passage filtration technology, and in particular to a dustproof building construction passage filtration device. Background Technology

[0002] Dust pollution is a prevalent and pressing environmental problem during construction. Construction access routes, as the core hubs for personnel, equipment, and building materials entering and exiting the construction site, are critical pathways for dust dispersion. Therefore, it is necessary to add dust filtration devices at these access routes to block dust dispersion paths and control the scope of pollution.

[0003] Currently, dust control measures in construction site access routes mostly involve using cable ties to secure dense safety nets to the outside of the access route. While the dense safety nets can block some large dust particles, the cable ties method of securing them creates gaps between the nets and the access route frame, allowing large amounts of dust to penetrate the access route and failing to form an effective air filtration barrier. Therefore, a dust-proof filtration device for construction access routes is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a dustproof building construction passage filtration device to solve the problems mentioned in the background art.

[0007] Preferably, the motor surface is covered with a motor cover.

[0008] Preferably, the two opposing surfaces of the support plates are fixedly connected to the adjacent surfaces of the two mounting frames, the front end face of the pull rod slides through the rear side of the support plate and extends to the front side of the support plate, the rear end face of the pull rod is fixedly connected to the front side of the pressure plate, and a pull plate is fixedly connected to the front end face of the pull rod.

[0009] Preferably, the front and rear ends of the spring are fixedly connected to the rear side of the support plate and the front side of the pressure plate, respectively; the front side of the pressure roller is fixedly connected to the rear side of the pressure plate; the rear side of the pressure roller is slidably connected to the front side of the filter screen; and the rear side of the filter screen is in contact with the front side of the channel frame.

[0010] Preferably, the mounting assembly includes a C-shaped frame fixedly connected to the rear side of the mounting frame. The inner right side of the C-shaped frame is fixedly connected to the inner side of the channel frame. A threaded rod is provided on the outer side of the C-shaped frame. The end face of the threaded rod extends through the outer side of the C-shaped frame to the inner side of the C-shaped frame. A threaded sleeve is threaded onto the surface of the threaded rod. The surface of the threaded rod is rotatably connected to the inner wall of the C-shaped frame through a bearing seat. A clamping plate is fixedly connected to the end face of the threaded sleeve. A sliding rod is fixedly connected to the outer side of the clamping plate. The end face of the sliding rod slides through the inner side of the C-shaped frame to the outer side of the C-shaped frame.

Combined with the tension control of the pressure rollers, the tension and coverage of the filter screen can be flexibly adjusted according to the actual size of the channel frame, ensuring that the filter screen remains flat and smooth, adapting to different specifications of construction channels, and guaranteeing stable filtration results. By installing the components, and utilizing the cooperation of the C-shaped frame, threaded rod, threaded sleeve, and clamping plate, rotating the threaded rod can drive the clamping plate to tightly press the channel frame support column with the friction plate. The friction plate increases the contact friction between the clamping plate and the channel frame, preventing the device from loosening or shifting during construction vibration. At the same time, after the locking rod is inserted into the locking hole, the position of the threaded rod can be fixed, further enhancing the connection stability and ensuring that the filter assembly remains stable during construction.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Example 1: Please refer to Figure 1 - Figure 8 The present invention provides a technical solution: a dustproof building construction passage filtration device, including a passage frame 1, with a filter component 20 and an installation component 21 provided on both the front and rear sides of the passage frame 1, and the installation component 21 located on the surface of the filter component 20; The filter assembly 20 includes two symmetrical mounting frames 201. A motor 202 is fixedly connected to the top surface of the mounting frame 201. A winding roller 203 is provided inside the mounting frame 201. A filter screen 204 and two support plates 206 are provided between the two mounting frames 201. A pull rod 207, a pressure plate 208 and a pressure roller 2010 are provided on the rear side of the support plate 206. A spring 209 is sleeved on the surface of the pull rod 207.

[0018] The bottom end face of the motor 202 output rod extends through the top surface of the mounting frame 201 and into the interior of the mounting frame 201. The bottom end face of the motor 202 output rod is fixedly connected to the top surface of the take-up roller 203. The bottom end face of the take-up roller 203 is rotatably connected to the bottom surface inside the mounting frame 201 through a bearing seat. The left and right end faces of the filter screen 204 are fixedly connected to the surfaces of the two take-up rollers 203 respectively.

[0019] The surface of the motor 202 is covered with a motor cover 205, which can effectively prevent dust and debris in the construction environment from entering the interior of the motor 202, reduce wear on parts, and extend the service life of the motor 202.

[0020] The two support plates 206 are fixedly connected to the adjacent surfaces of the two mounting frames 201 respectively. The front end of the pull rod 207 slides through the rear side of the support plate 206 and extends to the front side of the support plate 206. The rear end of the pull rod 207 is fixedly connected to the front side of the pressure plate 208. The front end of the pull rod 207 is fixedly connected to the pull plate 2011. The pull plate 2011 facilitates manual adjustment of the pull rod 207 and makes it convenient for the installation, disassembly and maintenance of the filter screen 204.

[0021] The front and rear ends of the spring 209 are fixedly connected to the rear side of the support plate 206 and the front side of the pressure plate 208, respectively. The front side of the pressure roller 2010 is fixedly connected to the rear side of the pressure plate 208. The rear side of the pressure roller 2010 is squeezed and slidably connected to the front side of the filter screen 204. The rear side of the filter screen 204 is in contact with the front side of the channel frame 1.

[0022] Through the filter assembly 20, the support plate 206, pull rod 207, pressure plate 208, spring 209, and pressure roller 2010 work together. The elastic force of the spring 209 pushes the pressure plate 208 to drive the pressure roller 2010 to continuously squeeze the filter screen 204, so that the rear side of the filter screen 204 is tightly fitted to the front side of the channel frame 1. This completely avoids the gaps caused by the defects of the fixing method of traditional dense mesh safety nets, blocks the dust leakage path, forms an effective air filtration barrier, and greatly improves the dust filtration efficiency. At the same time, the motor 202 drives the winding roller 203 to rotate, which can perform winding or unwinding operations on the filter screen 204. Combined with the tension control of the pressure roller 2010, the tension and coverage of the filter screen 204 can be flexibly adjusted according to the actual size of the channel frame 1, ensuring that the filter screen 204 is always flat and stretched, adapting to different specifications of construction channels, and ensuring stable filtration effect.

[0023] Example 2: Based on Example 1, a preferred embodiment of the dustproof building construction passage filtration device provided by this utility model is as follows: Figure 1 - Figure 3 , Figure 6 and Figure 8As shown: The mounting assembly 21 includes a C-shaped frame 211 fixedly connected to the rear side of the mounting frame 201. The inner right side of the C-shaped frame 211 is fixedly connected to the inner side of the channel frame 1. A threaded rod 214 is provided on the outer side of the C-shaped frame 211. The end face of the threaded rod 214 extends through the outer side of the C-shaped frame 211 to the inner side of the C-shaped frame 211. A threaded sleeve 215 is threaded on the surface of the threaded rod 214. The surface of the threaded rod 214 is rotatably connected to the inner wall of the C-shaped frame 211 through a bearing seat. A clamping plate 212 is fixedly connected to the end face of the threaded sleeve 215. A sliding rod 217 is fixedly connected to the outer side of the clamping plate 212. The end face of the sliding rod 217 slides through the inner side of the C-shaped frame 211 to the outer side of the C-shaped frame 211. The sliding rod 217 can limit the clamping plate to limit the movement of 212.

[0024] A friction plate 213 is fixedly connected to the side of the clamping plate 212. The side of the friction plate 213 is pressed against the surface of the channel frame 1, and the friction plate 213 increases the friction force when in contact with the support column of the channel frame 1.

[0025] A rotating plate is fixedly connected to the outer end face of the threaded rod 214. A locking rod 216 is provided on the outer side of the rotating plate. A locking hole adapted to the locking rod 216 is opened through the outer side of the C-shaped frame 211. The end face of the locking rod 216 slides through the side of the rotating plate and the outer side of the C-shaped frame 211 and extends into the locking hole. The locking rod 216 locks the threaded rod 214.

[0026] By installing component 21, and utilizing the cooperation of C-shaped frame 211, threaded rod 214, threaded sleeve 215, and clamping plate 212, rotating threaded rod 214 can drive clamping plate 212 to drive friction plate 213 to tightly press against the support column of channel frame 1. Friction plate 213 increases the contact friction between clamping plate 212 and channel frame 1, preventing the device from loosening or shifting during construction vibration. At the same time, locking rod 216 can fix the position of threaded rod 214 after being inserted into locking hole, further strengthening connection stability and ensuring that filter component 20 remains stable during construction.

[0027] It should be noted that the specific installation method of the motor, the connection method of the circuit, and the control method used in this utility model are all conventional designs, and will not be described in detail here.

[0028] The working principle of this utility model is as follows: Push the mounting frame 201 towards the front side of the channel frame 1, so that the C-shaped frame 211 moves to the outside of the support column of the channel frame 1. The inner side of the C-shaped frame 211 is initially in contact with the inner side of the channel frame 1, completing the pre-installation positioning. Pull out the locking rod 216 to release the rotation restriction of the threaded rod 214. Manually rotate the rotating plate to drive the threaded rod 214, so that the threaded sleeve 215 moves and drives the clamping plate 212 to move closer to the support column of the channel frame 1. The clamping plate 212 drives the friction plate 213 to move until the friction plate 213 fixed on the side of the clamping plate 212 is tightly pressed against the surface of the support column of the channel frame 1. The friction plate 213 increases the clamping friction, realizing a stable connection between the mounting frame 201 and the channel frame 1. Reinsert the locking rod 216 into the locking hole on the side of the rotating plate and the outer side of the C-shaped frame 211 to fix the position of the threaded rod 214 and prevent the clamping plate 212 from loosening, completing the overall installation of the device. Turn on the motor 202 fixed on the top surface of the mounting frame 201. The output rod of the motor 202 drives the winding roller 203 to rotate. When the winding roller 203 rotates, it performs a winding operation on the filter screen 204, collecting the excess filter screen 204 onto the surface of the winding roller 203, so that the filter screen 204 remains flat and stretched between the two mounting frames 201, fully covering the front side of the channel frame 1. During the winding process of the filter screen 204, the pressure roller 2010 contacts and squeezes the front side of the filter screen 204. After receiving the reaction force from the filter screen 204, the pressure roller 2010 pushes the pressure plate 208 fixed to its front side. The pressure plate 208 drives the pull rod 207 fixed at the front end to slide along the support plate 206. At the same time, the front and rear ends of the spring 209 sleeved on the surface of the pull rod 207 are fixed to the rear side of the support plate 206 and the front side of the pressure plate 208, respectively, and are compressed, generating a reverse elastic force. The elastic force is transmitted to the pressure roller 2010 through the pressure plate 208, so that the pressure roller 2010 continuously applies backward pressure to the filter screen 204, ensuring that the rear side of the filter screen 204 is tightly attached to the front side of the channel frame 1, avoiding the formation of dust leakage gaps. The tightly attached filter screen 204 forms an effective air filtration barrier, blocking the diffusion of dust in the construction environment through the channel frame 1. At the same time, the winding roller 203... The tension control of the winding adjustment and the pressure roller 2010 can be coordinated to flexibly adjust the tension of the filter screen 204 according to the actual size of the channel frame 1, ensuring a stable long-term filtration effect. Before the construction channel is dismantled, the locking rod 216 can be pulled out to loosen the clamp plate (212), which facilitates the overall disassembly and storage of the device. The filter screen 204 can be wound up and recycled by the winding roller 203 to achieve secondary reuse.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
