Detailed Implementation

[0047] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0048] like Figures 1 to 3 As shown, this utility model provides a lifting door device for a soundproof room, which may include a door frame 100, a lifting mechanism 200, a door body 300, and a counterweight mechanism 400. The door frame 100 may include a pair of vertically arranged mounting beams 110, the lifting mechanism 200 is connected to the pair of mounting beams 110, and the door body 300 is slidably disposed between the pair of mounting beams 110 and connected to the lifting mechanism 200. The counterweight mechanism 400 includes at least one pair, each pair being disposed on the outer side of the pair of mounting beams 100 and connected to both sides of the door body 300, for controlling the door body 300 to maintain balance during lifting and lowering.

[0049] Specifically, in the soundproof room lifting door device of this utility model, the door body 300 is slidably mounted between a pair of mounting beams 110 of the door frame 100. A lifting mechanism 200 is installed on the mounting beams 110 to drive the door body 300 to move up and down between the pair of mounting beams 110. To further ensure the smooth operation of the door body 300 during frequent opening and closing, a counterweight mechanism 400 is also installed on the outside of the mounting beams 100. The counterweight mechanisms 400 on the two mounting beams 110 are respectively connected to the two sides of the door body 300. Preferably, the pair of counterweight mechanisms 400 are connected to the bottom two sides of the door body 300. That is to say, the weight of the door body 300 is balanced by the pair of counterweight mechanisms 400, thereby making the lifting of the door body 300 smoother and more stable, avoiding shaking caused by accelerated descent due to its own weight or motor overload.

[0050] In addition, since the counterweight mechanism 400 of this utility model offsets part of the weight of the door body 300, the lifting mechanism 200 only needs to overcome friction and the remaining unbalanced force, which greatly reduces the power requirement of the lifting mechanism 200 and reduces production energy consumption.

[0051] In some embodiments, the lifting mechanism 200 may include a pair of conveyor belt mechanisms 210, which are respectively vertically disposed inside a pair of mounting beams 110, and the conveyor belts in the pair of conveyor belt mechanisms 210 are respectively connected to both sides of the door body 300.

[0052] As an example, such as Figure 4 and Figure 5 As shown, each conveyor belt mechanism 210 is installed on the inner side of the mounting beam 110. The conveyor belt mechanism 210 can be composed of a pair of transmission gears 211 and a conveyor belt 212 wound around the transmission gears 211. The pair of transmission gears 211 of a single conveyor belt mechanism 210 are installed on the inner side of the mounting beam 110, and the conveyor belt 212 is wound vertically around the pair of transmission gears 211. The two sides of the door body 300 are respectively connected to the conveyor belts 212 of the two conveyor belt mechanisms 210, so as to drive the door body 300 to rise and fall by driving the transmission belts 212.

[0053] Furthermore, the conveyor belt 212 can be a belt drive, which can buffer and dampen vibrations, making the door 300 run smoothly during lifting operations. Also, when the load on the lifting mechanism 200 suddenly increases (such as mechanical jamming), the belt may slip rather than break, preventing the drive source (e.g., drive motor) from burning out or mechanical parts from being damaged. The transmission gear 211 can be connected to the mounting beam 110 via a mounting base.

[0054] In some embodiments, such as Figure 4 and Figure 5As shown, the lifting mechanism 200 may also include a drive motor 220 and a synchronous shaft 230. The drive motor 220 is mounted on a mounting beam 110, and the synchronous shaft 230 is located between a pair of mounting beams 110. The synchronous shaft 230 is connected to a pair of corresponding transmission gears in a pair of conveyor belt mechanisms 210, and the output end of the drive motor 220 is connected to one end of the synchronous shaft 230.

[0055] In other words, the pair of conveyor belt mechanisms 210 are connected by a synchronous shaft 230. When the drive motor 220 drives the synchronous shaft 230 to rotate, it can drive the corresponding pair of transmission gears 211 in the pair of conveyor belt mechanisms 210 to rotate synchronously, thereby ensuring that the conveyor belts 212 on both sides are driven synchronously, and thus ensuring the balance and stability of both sides of the door 300 during the lifting process.

[0056] It should be noted that the output end of the drive motor 220 can be connected to the synchronous shaft 230 via a belt.

[0057] In some embodiments, such as Figure 6 As shown, connectors 310 are installed on both sides of the door body 300. A pair of connectors 310 are respectively located on the inner side of a pair of mounting beams 110, and the two sides of the door body 300 are connected to the conveyor belt of the conveyor belt mechanism 210 through the connectors 310.

[0058] In other words, connectors 310 are provided on both sides of the door body 300 to connect with the conveyor belt 212 of the conveyor belt mechanism 210 inside the mounting beam 110, thereby ensuring that the conveyor belt mechanism 210 drives the door body 300 to rise and fall stably. It should be noted that the connectors 310 on both sides are symmetrically arranged with respect to the central axis of the door body 300.

[0059] In some embodiments, such as Figure 6 and Figure 7 As shown, the counterweight mechanism 400 may include a counterweight block 410, a pulley assembly 420, and a steel wire rope (not shown). The counterweight block 410 is slidably connected to the outer side of the mounting beam 110. The pulley assembly 420 is connected to the top of the mounting beam 110. One end of the steel wire rope is connected to the counterweight block 410, and the other end is wound around the pulley assembly 420 to connect to one side of the door body 300.

[0060] Specifically, a counterweight 410 is provided on the outer side of the mounting beam 110. The counterweight 410 can slide up and down on the outer side of the mounting beam 110, while a pulley assembly 420 is fixedly installed on the top of the mounting beam 110. One end of a steel wire rope is connected to the counterweight 410 on the outer side of the mounting beam 110, and the other end is wound around the pulley assembly 420 to connect to one side of the door body 300 on the inner side of the mounting beam 110. When the door body 300 is raised or lowered, the counterweight 410 also moves in the opposite direction along with the door body 300, thereby achieving the counterweight of the door body 300.

[0061] Preferably, with the central axis of the door body 300 as the axis of symmetry, the connection points of the steel wire ropes of the pair of counterweight mechanisms 400 with the door body 300 are symmetrical. This ensures the balance of both sides of the door body 300 during counterweighting.

[0062] In some embodiments, such as Figure 7 As shown, a pair of first slide rails 120 are vertically arranged on the outer surface of the mounting beam 110, and a vertical first groove 121 is formed on the opposite surface of the pair of first slide rails 120. Protrusions (not shown) are formed on both sides of the counterweight 410, and the protrusions are slidably disposed inside the first groove 121 so that the counterweight 410 can be slidably connected between the pair of first grooves 121.

[0063] In other words, a pair of first slide rails 120 are vertically arranged on the outer side of the mounting beam 110. The two sides of the counterweight 410 are slidably connected to the first groove 121 of the pair of first slide rails 120 through protrusions, so as to limit the lifting path of the counterweight 410 and avoid the door 300 from shaking due to the imbalance of the counterweight.

[0064] In some embodiments, such as Figure 7 As shown, the pulley assembly 420 may include a mounting plate 421 and at least a pair of pulleys 422. One end of the mounting plate 421 is connected to the outer surface of the mounting beam 110, and the other end extends through the mounting beam 110 to the inner surface of the mounting beam 110. One pulley 422 is connected to the end of the mounting plate 110 located on the outer surface of the mounting beam 110, and the other pulley 422 is connected to the end of the mounting plate 421 located on the inner surface of the mounting beam 110. The other end of the wire rope passes sequentially around the pulleys 422 on the outer and inner surfaces of the mounting beam 110 to connect to the door body 300. This ensures that the wire rope can stably connect the counterweights 410 at both ends and the door body 420, and that the wire rope can smoothly rise and fall without interference.

[0065] In some embodiments, such as Figure 2As shown, the lifting door device of the soundproof room may also include a pair of second slide rails 130. The pair of second slide rails 130 are arranged opposite to each other and are respectively connected to the inner sides of a pair of mounting beams 110. Vertical second grooves 131 are formed on the opposite sides of the pair of second slide rails 130. Guide wheels (not shown) are respectively connected to both sides of the door body 300. The guide wheels are slidably connected in the second grooves 131, and the door body 300 can be slidably connected to the pair of second slide rails 130 up and down through the guide wheels.

[0066] Therefore, the rigid constraint of the second slide rail 130 (such as rollers or sliders) can prevent the door 300 from swaying or tilting during the lifting process, ensuring the linearity of vertical or diagonal movement. It also ensures that the door 300 always moves along a preset path, preventing the door 300 from falling uncontrollably due to unbalanced counterweights, broken wire ropes, or other accidents, thus ensuring the stability of the lifting process.

[0067] In some embodiments, the lifting door device of the soundproof room may also include a fall protection device, which includes at least one pair, and the two sides of the door 300 are respectively connected to the inner side of the mounting beam 110 through a pair of fall protection devices.

[0068] As an example, such as Figure 2 As shown, the fall arrestor may include a third slide rail 140 and an internal locking fall arrestor (not shown). A third slide rail 140 is also installed on the inner side of a pair of mounting beams 110. The third slide rail 140 is located on one side of the second slide rail 130 and is parallel to the second slide rail 130. A vertical third groove 141 is formed on the opposite sides of the pair of third slide rails 140. An internal locking fall arrestor is slidably connected within the third groove 141, and the internal locking fall arrestor is connected to one side of the door body 300.

[0069] Therefore, when the steel wire rope, connectors and other load-bearing components used for lifting the gate 300 break, the internal locking anti-fall device can immediately lock the third slide rail 140 and the gate 300, preventing the gate 300 from falling at high speed and causing injury to personnel or damage to equipment, and further ensuring the smooth lifting and lowering operation of the gate 300.

[0070] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
