Description

Technical Field

[0001] This utility model belongs to the field of roof technology, specifically an openable warehouse roof. Background Technology

[0002] Open warehouses or storage yards used for storing bulk goods are mostly open-air, and the stored goods are easily exposed to wind and sun. Moreover, these goods are usually fine and light, and a lot of dust will be stirred up by the wind every day. Therefore, spraying equipment is usually used to spray and suppress dust during operation, and a canopy is set up above the open warehouses or storage yards.

[0003] Most existing canopies are retractable, unfolding during operation to improve dust suppression and retracting during drying yards or snowy weather to prevent damage and extend their lifespan. The current method involves multiple motors on both sides of the canopy: one for retracting the net and the other for releasing it. These motors control the opening and closing of the canopy. This method requires coordination between the motors, resulting in a complex structure and high precision requirements. This leads to high initial construction costs and high maintenance costs for the motors later on. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides an openable warehouse roof that simultaneously enables the netting to be raised and lowered via a drive system, reducing the number of motors, simplifying the structure, and lowering costs.

[0005] This utility model provides an openable warehouse roof, including a windproof structure arranged around the perimeter. Multiple main steel wire ropes are arranged between the top of the windproof structure. A top net is slidably connected to the main steel wire ropes. One end of the top net is fixed to the top of the windproof structure on one side, and the other end of the top net slides on the main steel wire rope. A drive system is provided on the windproof structure to drive the top net to be retracted and deployed.

[0006] Furthermore, multiple netting connectors are slidably connected to the main wire rope along its length, and the top netting is fixed to the netting connectors and slides on the main wire rope through the netting connectors.

[0007] Furthermore, the netting connector includes a pulley mounting bracket, on which two netting pulleys are rotatably connected. The main steel wire rope passes between the two netting pulleys, and the netting pulleys slide on the main steel wire rope. An mounting plate is fixed to the bottom of the pulley mounting bracket, and the top netting is fixed to the mounting plate.

[0008] Furthermore, the drive system includes a motor and a reducer. The output shaft of the motor is connected to the reducer, and at least two rollers are connected to the output shaft of the reducer. The drive system also includes a trawl frame, which is fixed to the top of the pulley mounting bracket at the foremost side of the sliding end of the top net. Two traction ropes are connected to both sides of the trawl frame. A first fixed pulley is rotatably connected to the top of the windproof structure near the sliding end of the top net. One traction rope is wound around a roller at the end away from the trawl frame, and the other traction rope is wound around another roller after passing around the first fixed pulley at the end away from the trawl frame.

[0009] Furthermore, the motor, reducer, and roller are located at the bottom of the windproof structure, and the top of the windproof structure where the motor is installed is rotatably connected to two second fixed pulleys. One end of the traction rope away from the trawl frame passes around one of the second fixed pulleys and then wraps around a roller. The other end of the traction rope away from the trawl frame passes around the first fixed pulley and another second fixed pulley in sequence and then wraps around another roller.

[0010] Furthermore, at least two connecting frames are fixed to the top of the trawl frame, and pins are inserted into the top of the connecting frames. One traction rope is fixedly connected to the pin on one connecting frame, and the other traction rope is fixedly connected to the pin on the other connecting frame.

[0011] Furthermore, multiple motors are arranged along the length of the windproof structure, and synchronizers are installed between the multiple motors.

[0012] Furthermore, limiters are installed at both ends of the main wire rope, and the pulley mounting bracket abuts against the limiters after it moves into place.

[0013] Furthermore, at least one supporting structure is provided around the windproof structure. The main steel wire rope is set between the top of the windproof structure and the top of the supporting structure. One end of the top net is fixed to the top of the supporting structure, and the other end of the top net slides on the main steel wire rope with the sliding end close to the windproof structure. The drive system is set on the supporting structure; or one end of the top net is fixed to the top of the windproof structure, and the other end of the top net slides on the main steel wire rope with the sliding end close to the supporting structure. The drive system is set on the windproof structure.

[0014] Furthermore, a connecting plate is fixedly connected to the end of the main wire rope near the windproof structure, a safety bar is connected to the connecting plate, the end of the safety bar away from the connecting plate is fixed to the windproof structure, a safety rope is also connected to the connecting plate, and the end of the safety rope away from the connecting plate is also fixed to the windproof structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) When the motor rotates, the motor drives the drum to rotate through the reducer. When the drum rotates, the traction rope on one drum is tightened and the traction rope on the other drum is released. The tightened traction rope pulls the trawl frame to move towards the fixed end of the top net. The trawl frame drives the sliding end of the top net to move towards the fixed end of the top net, thereby realizing the net being pulled in. Similarly, when the motor rotates in the opposite direction, the motor drives the drum to rotate in the opposite direction through the reducer. The previously tightened traction rope is released and the previously released traction rope is tightened. At this time, the tightened traction rope will pull the trawl frame to move away from the fixed end of the top net through the first fixed pulley. The trawl frame will then drive the sliding end of the top net to move away from the fixed end of the top net, thereby realizing the net being released. In short, this driving method is a "one-drive two-rope" method, that is, by using one motor and two traction ropes, the net being pulled in and released is realized by using the forward and reverse rotation of the motor. The structure is simple and the number of motors is reduced, thus reducing the cost.

[0017] (2) This utility model uses a second fixed pulley to lower the connection end of the traction rope and the drum to the bottom of the windproof structure, while also ensuring that the connection end of the traction rope and the trawler frame can move horizontally. This allows the motor, reducer and drum to be installed at the bottom of the windproof structure, which facilitates the later maintenance of the motor, reducer and drum.

[0018] (3) When the top net is subjected to a large load, the safety bar will break. After the safety bar breaks, the connecting plate and the top net will fall downward. At this time, the connecting plate stretches the tension spring. The tension spring uses its own elasticity to unload the force of the connecting plate and the top net falling downward, thereby preventing the windproof structure and the top net from being damaged when subjected to a large load, and extending the service life of the windproof structure and the top net.

[0030] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The present invention will be described in detail with specific embodiments.

[0032] Example 1

[0033] Reference Figures 1-5This utility model provides an openable warehouse roof, including a surrounding windproof structure 1. The windproof structure 1 can be a windproof net or a windproof wall; the specific structural form of the windproof structure 1 is not specifically limited in this utility model. Multiple main steel wire ropes 3 are arranged between the top sections of the windproof structure 1. A top net 4 is slidably connected to the main steel wire ropes 3. One end of the top net 4 is fixed to the top of one side of the windproof structure 1, and the other end slides on the main steel wire ropes 3. A drive system 5 is provided on the windproof structure 1 to drive the top net 4 to retract and extend.

[0034] Multiple netting connectors 6 are slidably connected to the main wire rope 3 along its length. The top net 4 is fixed to the netting connectors 6 and slides on the main wire rope 3 via the netting connectors 6. The netting connector 6 includes a pulley mounting bracket 60, on which two netting pulleys 61 are rotatably connected. The main wire rope 3 passes between the two netting pulleys 61, and the netting pulleys 61 slide on the main wire rope 3. A mounting plate 62 is fixed to the bottom of the pulley mounting bracket 60, and the top net 4 is fixed to the mounting plate 62. The top net 4 is fixed to the pulley mounting bracket 60 via the mounting plate 62, and the netting pulleys 61 are rotatably connected to the pulley mounting bracket 60. The netting pulleys 61 slide on the main wire rope 3, thereby enabling the top net 4 to slide on the main wire rope 3.

[0035] The drive system 5 includes a motor 50 and a reducer 51. The output shaft of the motor 50 is connected to the reducer 51. At least two rollers 52 are connected to the output shaft of the reducer 51. The drive system 5 also includes a net frame 53. The net frame 53 is fixed to the top of the pulley mounting bracket 60 at the frontmost side of the sliding end of the top net 4. Two traction ropes 54 are connected to both sides of the net frame 53. A first fixed pulley 55 is rotatably connected to the top of the windproof structure 1 near the sliding end of the top net 4. One end of the traction rope 54 away from the net frame 53 is wound around a roller 52. The other end of the traction rope 54 away from the net frame 53 passes around the first fixed pulley 55 and is wound around another roller 52. When motor 50 rotates, it drives drum 52 to rotate via reducer 51. As drum 52 rotates, the traction rope 54 on one drum 52 tightens, while the traction rope 54 on the other drum 52 releases. The tightened traction rope 54 pulls the trawl frame 53 towards the fixed end of the top net 4. The trawl frame 53 then moves the sliding end of the top net 4 towards the fixed end, thus achieving the retrieval of the top net 4. Similarly, when motor 50 rotates in the opposite direction, it drives drum 52 to rotate in the opposite direction via reducer 51, and the previously tightened traction rope 54... The net is released, and the previously released traction rope 54 is tightened. At this time, the tightened traction rope 54 will pull the trawl frame 53 to move away from the fixed end of the top net 4 through the first fixed pulley 55. The trawl frame 53 will then drive the sliding end of the top net 4 to move away from the fixed end of the top net 4, thereby realizing the release of the top net 4. Simply put, this driving method is a "one-drive two-rope" method, that is, the top net 4 is released and retrieved by using one motor 50 and two traction ropes 54, and the forward and reverse rotation of the motor 50 is used to realize the release and retrieval of the top net 4. The structure is simple and the number of motors 50 is reduced, thus reducing the cost.

[0036] The motor 50, reducer 51, and roller 52 are located at the bottom of the windproof structure 1. Two second fixed pulleys 56 are rotatably connected to the top of the windproof structure 1 where the motor 50 is mounted. One end of a traction rope 54, away from the trawl frame 53, passes over one second fixed pulley 56 and then winds around a roller 52. The other end of a traction rope 54, away from the trawl frame 53, passes over a first fixed pulley 55 and another second fixed pulley 56 in sequence and then winds around another roller 52. This invention uses the second fixed pulleys 56 to lower the connection end of the traction rope 54 to the bottom of the windproof structure 1, while also ensuring that the connection end of the traction rope 54 to the trawl frame 53 can move horizontally. This allows the motor 50, reducer 51, and roller 52 to be installed at the bottom of the windproof structure 1, facilitating future maintenance of the motor 50, reducer 51, and roller 52.

[0037] At least two connecting brackets 57 are fixed to the top of the trawl frame 53. Pins 58 are inserted into the top of each connecting bracket 57. One traction rope 54 is fixedly connected to the pin 58 on one connecting bracket 57, and the other traction rope 54 is fixedly connected to the pin 58 on the other connecting bracket 57. Additionally, it should be noted that... Figure 2 The trawl frame 53 shown is only one corner of the trawl frame 53, not the entire trawl frame 53. When the traction rope 54 moves, the traction rope 54 drives the connecting frame 57 to move through the pin 58, and the connecting frame 57 drives the trawl frame 53 to move, thereby realizing the movement of the trawl frame 53 by the traction rope 54.

[0038] Multiple motors 50 are arranged along the length of the windproof structure 1. Synchronizers are installed between the multiple motors 50 to ensure that the multiple motors 50 rotate synchronously, thereby ensuring the consistency of movement of each part of the top net 4 when the net is being pulled in and released.

[0039] Limiters 7 are provided at both ends of the main wire rope 3. In this embodiment, since both ends of the main wire rope 3 are located at the top of the windproof structure 1, the limiters 7 are also located at the top of the windproof structure 1. After the pulley mounting bracket 60 moves into place, it abuts against the limiter 7. The limiter 7 has the function of limiting the movement position of the pulley mounting bracket 60. When the top net 4 moves into place for net retrieval or net release, the pulley mounting bracket 60 will abut against the limiter 7. At this time, the motor 50 will stop rotating, indicating that the top net 4 has been retrieved or released into place, preventing the top net 4 from moving excessively and damaging the top net 4.

[0040] A connecting plate 8 is fixedly connected to the end of the main steel wire rope 3 near the windproof structure 1. A safety rod 9 is connected to the connecting plate 8, and the end of the safety rod 9 away from the connecting plate 8 is fixed to the windproof structure 1. A safety rope 10 is also connected to the connecting plate 8, and the end of the safety rope 10 away from the connecting plate 8 is also fixed to the windproof structure 1. In this embodiment, the safety rope 10 is a tension spring. When the top net 4 is subjected to a large load, the safety rod 9 will break. After the safety rod 9 breaks, the connecting plate 8 and the top net 4 will fall downwards. At this time, the connecting plate 8 stretches the tension spring, and the tension spring uses its own elasticity to unload the downward force of the connecting plate 8 and the top net 4, thereby preventing damage to the windproof structure 1 and the top net 4 when subjected to a large load and extending the service life of the windproof structure 1 and the top net 4.

[0041] Example 2

[0042] Reference Figures 6-9The difference between this embodiment and Embodiment 1 is that at least one supporting structure 2 is provided around the windproof structure 1. This embodiment specifically provides one supporting structure 2 for ease of structural description. Of course, multiple supporting structures 2 can be provided in the middle to improve the supporting effect, depending on the size of the site. This invention does not specifically limit the number of supporting structures 2. Furthermore, the supporting structure 2 in this embodiment is specifically a steel frame. Of course, the supporting structure 2 can also be other structures with supporting functions. This invention does not specifically limit the specific structural form of the supporting structure 2.

[0043] The main steel wire rope 3 is positioned between the top of the windproof structure 1 and the top of the supporting structure 2. One end of the top net 4 is fixed to the top of the supporting structure 2, and the other end of the top net 4 slides on the main steel wire rope 3 with the sliding end close to the windproof structure 1. The drive system 5 is mounted on the supporting structure 2. Alternatively, one end of the top net 4 is fixed to the top of the windproof structure 1, and the other end of the top net 4 slides on the main steel wire rope 3 with the sliding end close to the supporting structure 2. The drive system 5 is mounted on the windproof structure 1. Both methods are feasible, differing only in the installation position of the drive system 5 and the direction of movement of the top net 4. Both are within the protection scope of this utility model, and the two methods will be described in detail below.

[0044] When one end of the top net 4 is fixed to the top of the windproof structure 1, and the other end of the top net 4 slides on the main steel wire rope 3 with the sliding end close to the support structure 2, and the drive system 5 is set on the windproof structure 1, the motor 50, reducer 51 and roller 52 in the drive system 5 are installed at the bottom of the windproof structure 1, the first fixed pulley 55 is set on the top of the support structure 2, and the second fixed pulley 56 is set on the top of the windproof structure 1. In this way, the structure of the drive system 5 is similar to that in embodiment 1, so it is not shown in the figure. When the net is pulled in, the top net 4 on both sides of the support structure 2 is pulled in away from the support structure 2. When the net is released, the top net 4 on both sides of the support structure 2 is released towards the support structure 2.

[0045] When one end of the top net 4 is fixed to the top of the support structure 2, and the other end of the top net 4 slides on the main steel wire rope 3 with the sliding end close to the windproof structure 1, and the drive system 5 is installed on the support structure 2, such as Figures 6-9 As shown, the motor 50, reducer 51 and roller 52 in the drive system 5 are installed at the bottom of the support structure 2. The first fixed pulley 55 is set at the top of the windproof structure 1 and the second fixed pulley 56 is set at the top of the support structure 2. When the net is pulled in, the top net 4 on both sides of the support structure 2 is pulled in towards the support structure 2. When the net is released, the top net 4 on both sides of the support structure 2 is released away from the support structure 2.

[0046] In a preferred embodiment, the support structure 2 has a trawl frame 53, traction rope 54, first fixed pulley 55, and second fixed pulley 56 with the same structure on both sides. The traction ropes 54 on both sides of the support structure 2 are wound around the rollers 52 at the bottom of the support structure 2. In this embodiment, there are four rollers 52. The four rollers 52 rotate coaxially with the motor 50 and the reducer 51. Each side of the support structure 2 has two traction ropes 54, and both sides have four traction ropes 54. The four traction ropes 54 are wound around the four rollers 52 respectively. Therefore, this driving method is a "one-drive-four-rope" method, that is, by using one motor 50 and four traction ropes 54, the forward and reverse rotation of the motor 50 can simultaneously drive the top net 4 on both sides of the support structure 2 to synchronously collect and release the net, further reducing the number of motors 50.

[0047] Limiters 7 are provided at both ends of the main wire rope 3. Since the two ends of the main wire rope 3 are respectively located at the top of the windproof structure 1 and the top of the support structure 2 in this embodiment, the limiters 7 are also located at the top of the windproof structure 1 and the top of the support structure 2.

[0048] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
