Description

Technical Field

[0001] This utility model relates to the field of counterweight door technology, and in particular to a vertical lifting counterweight door. Background Technology

[0002] A counterweighted door is a type of door device that uses a counterweight balancing system to achieve smooth opening and closing. It is widely used in industrial, commercial, and residential buildings, and has many advantages and characteristics.

[0003] In existing technologies, the raising and lowering of doors mainly relies on electric or hydraulic drive technologies, but these technologies have many problems in practical applications.

[0004] For example, electric drive systems have high energy consumption. Electric motors consume a lot of electrical energy during startup and operation, especially in scenarios where doors are frequently opened and closed, where energy consumption is particularly prominent.

[0005] For example, the opening and closing speed of the hydraulic drive system is limited by the flow rate of the hydraulic oil, making it difficult to meet the high-frequency opening and closing requirements of the door. Secondly, the hydraulic system requires regular replacement of hydraulic oil and seals, making maintenance complex and costly.

[0006] Furthermore, existing counterweight gate systems mostly rely on electronic sensors for safety protection. If the sensors malfunction or there is a power outage, the gate may fall unexpectedly, posing a safety hazard. Utility Model Content

[0054] In this invention, 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 one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] Given that the existing technology has many problems with the drive devices that drive the door to lift and lower, and that the counterweight door system relies on electronic sensors for safety protection, there are potential safety hazards.

[0056] like Figures 1-7 As shown, this utility model embodiment provides a vertical lifting counterweight door, including: door body 1, frame 2, pneumatic drive assembly 3, counterweight block 4, balance drive component 5, and anti-fall drive component 6, etc.

[0057] The door 1 is slidably mounted on the frame 2 and configured to dock with the cavity, thus forming an independent cavity. A pneumatic drive assembly 3 is mounted on the frame 2 and connected to the door 1, driving the door 1 to reciprocate under the control of the control system. A counterweight 4 is located inside the frame 2 and moves in the opposite direction to the door 1. A balancing drive component 5 is mounted on the frame 2, with one end connected to the counterweight 4 and the other end connected to the door 1. The balancing drive component 5 causes the counterweight 4 and the door 1 to move in opposite directions, optimizing the stability and safety of the door 1's movement through mechanical balance. An anti-fall drive component 6 is mounted on the frame 2, with one end connected to the counterweight 4 and the other end connected to the door 1. The anti-fall drive component 6 further ensures the opposite movement of the counterweight 4 and the door 1, further improving the safety of the door 1's movement.

[0058] Specifically, such as Figure 1 As shown, the door body 1 includes a door body 11 and door ears 13 symmetrically arranged on the top of the door body 11. Wherein, as... Figures 3-4 As shown, guide wheels 12 are arranged opposite each other on the door body 11, and the guide wheels 12 can slide freely on the frame 2. Preferably, in this embodiment, there are 4 guide wheels 12, which are respectively located opposite each other and symmetrically on the side of the door body 11.

[0059] Furthermore, to improve the overall performance of the door body 1, in this embodiment, the door body 1 is covered with an anti-corrosion coating.

[0060] The inner sidewalls of the frame 2 are symmetrically provided with guide rails extending along the length of the frame 2. The guide wheel 12 is placed in the guide rail and slides freely along the predetermined direction of the guide rail.

[0061] More specifically, such as Figures 2-6 As shown, the frame 2 is divided into an upper frame 21 and a lower frame 23 from top to bottom. The upper frame 21 and the lower frame 23 can be integrally formed or fixed in a detachable manner. The guide rails on the inner side of the upper frame 21 are called first guide rails 22, and each first guide rail 22 adopts an integral structure. The guide rails on the inner side of the lower frame 23, corresponding to the first guide rails 22, are called second guide rails 24. Unlike the first guide rails 22, each second guide rail 24 adopts a segmented structure; that is, as shown... Figure 6As shown, each second guide rail 24 is composed of multiple fixed guide rail segments 241 and multiple sliding guide rail segments 242 arranged at intervals. Preferably, in this embodiment, each second guide rail 24 is composed of three fixed guide rail segments 241 and two sliding guide rail segments 242 arranged at intervals. The fixed guide rail segments 241 are located on the same plane as the first guide rail 22, while the sliding guide rail segments 242 are located on the same plane as the fixed guide rail segments 241 and the first guide rail 22 or are not on the same plane. When the sliding guide rail segment 242 slides, it is in a misaligned state with the fixed guide rail segments 241 and the first guide rail 22, i.e., not on the same plane. When the sliding guide rail segment 242 does not slide, it is located on the same plane as the fixed guide rail segments 241 and the first guide rail 22.

[0062] Furthermore, such as Figure 7 As shown, a locking cylinder 7 is also provided on the lower frame 23. The number of locking cylinders 7 corresponds to the number of sliding guide sections 242, and the output shaft of the locking cylinder 7 is connected to the sliding guide section 242. The locking cylinder 7 drives the sliding guide section 242 to slide and locks the sliding position of the sliding guide section 242. The working principle of the locking cylinder 7 is existing technology and will not be described in detail here.

[0063] The pneumatic drive assembly 3 mainly includes: lifting cylinder 31, air source (not shown in the figure), air pipe (not shown in the figure), solenoid valve (not shown in the figure), etc.

[0064] The lifting cylinders 31 are symmetrically arranged on opposite sides of the frame 2, and the output shafts of the two lifting cylinders 31 are respectively connected to the two door ears 13. An air source provides compressed air to the lifting cylinders 31. One end of an air pipe is connected to the air source, and the other end is connected to the lifting cylinder 31, thus transmitting compressed air. A solenoid valve is also installed on the air pipe. The solenoid valve receives signals from the control system and controls the intake and exhaust of the lifting cylinders 31 through these signals, thereby controlling the extension and retraction of the output end of the lifting cylinders 31 and realizing the reciprocating movement of the door 1.

[0065] like Figure 2 As shown, the counterweight 4 is located inside the upper frame 21 and can move in the opposite direction as the door 1 moves. The shape of the counterweight 4 can be a cuboid or a cylinder, as long as the center of gravity of the counterweight 4 is stable and the swaying is reduced. The counterweight 4 is used to balance the weight of the door 1 and improve the stability of the door 1's movement.

[0066] Furthermore, in order to counteract the weight of the door 1, reduce the operating force, and avoid excessive inertia leading to loss of control, in this embodiment, the weight of the counterweight 4 is approximately 90%-95% of the weight of the door 1.

[0067] Furthermore, to make the counterweight 4 suitable for door bodies 1 of different weights, the weight of the counterweight 4 in this embodiment can be set to an adjustable mode. For example, the counterweight 4 can be divided into multiple independent units (e.g., 5kg / unit), and the weight of the counterweight 4 can be increased or decreased by bolt assembly.

[0068] Furthermore, to prevent the counterweight 4 from swaying randomly during movement and to further improve the stability of the door 1's movement, in this embodiment, as follows... Figure 2 As shown, a guide rod 8 is provided at the middle position of the inner side of the upper frame 21. The guide rod 8 passes through the counterweight 4, with one end fixed to the top of the upper frame 21 and the other end fixed to the bottom of the upper frame 21. During the movement, the counterweight 4 moves along the direction of the guide rod 8.

[0069] like Figure 2 As shown, the balance drive component 5 mainly includes several parts such as sprocket 51 and chain 52.

[0070] The sprockets 51 are symmetrically fixed on the outer top wall of the upper frame 21. Each sprocket 51 is equipped with a chain 52, which passes through the sprocket 51. One end of the chain 52 is fixedly connected to the door body 11, and the other end is fixedly connected to the counterweight 4. Preferably, in this embodiment, the chain 52 is a parallel spare chain 52, that is, a double chain 52 design is adopted to prevent the risk of the counterweight 4 falling due to a single chain design. The counterweight 4 moves in the opposite direction to the door body 1 through the balance drive 5.

[0071] like Figure 3 As shown, the fall protection drive component 6 mainly includes: pulley 61 and fall protection wire rope 62.

[0072] The pulleys 61 are symmetrically fixed on the inner side wall of the top of the upper frame 21. Each pulley 61 is equipped with an anti-fall steel wire rope 62, which passes through the pulley 61. One end of the anti-fall steel wire rope 62 is fixedly connected to the door body 11, and the other end is fixedly connected to the counterweight 4. When the door body 1 is in a normal reciprocating movement state, the anti-fall steel wire rope 62 is in a slack state. When the door body 1 is in an emergency fall state, the anti-fall steel wire rope 62 is in a taut state under the interaction of the counterweight 4 and the door body 1. At this time, the emergency fall of the door body 1 is relieved by the action of the anti-fall steel wire rope 62 and the pulleys 61, avoiding personal injury and further improving the safety of the door body 1 during use.

[0073] In use, when the door 1 needs to be closed, the control system sends a signal to open the solenoid valve, and the lifting cylinder 31 starts to drive the guide wheel 12. The guide wheel 12 carries the door 1 downward along the direction of the first guide rail 22 and the fixed guide rail section 241. When the four guide wheels 12 move to the positions corresponding to the four sliding guide rail sections 242, the solenoid valve closes, the lifting cylinder 31 stops moving, and at the same time, the four locking cylinders 7 are activated. The four locking cylinders 7 drive the four sliding guide rail sections 242 to slide. The door 1 slides synchronously under the drive of the four sliding guide rail sections 242 until it docks with the cavity. At this time, the locking cylinder 7 is activated to lock the door 1 by controlling the air pressure in the locking cylinder 7, so that the door 1 is kept in the closed state.

[0074] When it is necessary to open the door 1, the locking cylinder 7 is activated. The locking cylinder 7 drives the sliding guide section 242 to slide, so that the sliding guide section 242 is on the same horizontal plane as the fixed guide section 241 and the first guide rail 22. Then, the lifting cylinder 31 is activated. The lifting cylinder 31 drives the guide wheel 12. The guide wheel 12 carries the door 1 to move upward along the direction of the fixed guide section 241 and the first guide rail 22. When the door 1 rises to the set position, the lifting cylinder 31 is closed, the door 1 stops moving, and the door 1 remains in the open state.

[0075] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
