Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle-mounted container roofs, and particularly relates to a vehicle-mounted container flat-push roof. Background Technology

[0002] Vehicle-mounted modular shelters are box-shaped devices mounted on special vehicle platforms used in geological exploration, water conservancy projects, construction projects, and military field operations that require outdoor work or combat. Upon arrival at the destination, the vehicle-mounted modular shelter can remain on the special vehicle platform or be lifted to the ground by a crane, offering great flexibility and convenience. The vehicle-mounted modular shelter has an openable top cover, which allows for the extension of communication equipment antennas or access to other equipment within the shelter.

[0003] Currently, the existing shelter roof is a rack and pinion linkage cover, which has the main problem of poor sealing effect. Because it is a linear pushing motion, the cover opening must have a gap to prevent interference. Therefore, after the roof covers the equipment opening, one side will inevitably not be sealed properly, which can easily cause rain and dust to enter the equipment room and lead to equipment damage. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a vehicle-mounted modular shelter flat-push top cover.

[0005] To solve the above problems, the present invention adopts the following technical solution: A vehicle-mounted modular shelter push-pull roof includes a roof and a skylight on the top of the shelter. A water-retaining baffle is provided around the top edge of the skylight, extending upwards. The roof can be closed by covering the top of the water-retaining baffle to seal the skylight. A push-pull mechanism for moving the roof back and forth is provided on the front side of the roof. The push-pull mechanism includes a motor, a lead screw, a nut, and a connecting plate. The motor is mounted on the top of the shelter. One end of the lead screw is driven and connected to the output shaft of the motor. The nut is threaded onto the lead screw. The connecting plate is connected to the nut. The front end of the roof is hinged to the connecting plate. Guide rails are installed on both sides of the roof opening. The guide rails are installed on the top of the container. Rear pulleys are installed on both sides of the roof opening. The rear pulleys on both sides of the roof are rotatably connected to the two guide rails. The ends of the guide rails are bent downward to form curved sections, while the rest are straight sections. When the rear pulleys are in the straight sections of the guide rails, the ends of the roofs are raised upward, and their height is higher than the top of the flood barrier. When the rear pulleys move backward to the curved sections of the guide rails, the roofs rotate around their front hinges, and the ends of the roofs are then pressed down by the pulleys and pressed tightly against the top of the flood barrier.

[0006] Preferably, linear slide rails are provided on the left and right sides of the lead screw, and the linear slide rails are installed on the top of the container. Front pulleys are provided on the left and right sides of the connecting plate, and the front pulleys on the left and right sides of the connecting plate are respectively rotatably connected in the two linear slide rails.

[0007] Preferably, the top of the water-blocking panel is provided with a sealing ring.

[0008] Preferably, the motor is a combined hand and electric motor.

[0009] Preferably, the nut is a ball nut that mates with the lead screw.

[0010] Preferably, the front and rear ends of the lead screw are connected to the top of the container via bearing seats.

[0011] Preferably, the front end of the top cover is connected to the connecting plate via a hinge.

[0012] Preferably, the lead screw is fitted with an accordion-style protective cover, the front end of which is fixedly connected to the top of the container, and the rear end is connected to the connecting plate.

[0013] The beneficial effects of this utility model are: Compared with existing technologies, the advantages of this utility model are: This utility model uses a hinged design where the curved section at the end of the guide rail is connected to the top cover, allowing the end of the top cover to rotate and press down when closed. This avoids the problem of leaving a gap to prevent interference between the top cover and the water-blocking plate, structurally solving the defect of traditional top covers not sealing properly and reducing the possibility of rain leakage and dust entering.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-5 As shown, this utility model provides a technical solution: a vehicle-mounted modular shelter push-pull top cover, including a top cover 1 and a skylight 2 opened on the top of the modular shelter. A water-retaining baffle 21 extending upwards is provided around the top edge of the skylight 2. The top cover 1 can be closed by covering the top of the water-retaining baffle 21 to form a seal on the skylight 2. A push-pull mechanism 3 for pushing the top cover 1 to move back and forth is provided on the front side of the top cover 1. The push-pull mechanism 3 includes a motor 31, a lead screw 32, a nut, and a connecting plate 34. The motor 31 is mounted on the top of the modular shelter. One end of the lead screw 32 is drivenly connected to the output shaft of the motor 31. The nut is threadedly connected to the lead screw 32. The connecting plate 34 is connected to the nut. The front end of the top cover 1 is hinged to the connecting plate 34. On the connecting plate 34, guide rails 4 are respectively provided on the left and right sides of the skylight 2. The guide rails 4 are installed on the top of the container. Rear pulleys 11 are respectively provided on the left and right sides of the top cover 1. The rear pulleys 11 on the left and right sides of the top cover 1 are respectively rolled and connected in the two guide rails 4. The end of the guide rail 4 is bent downward to form a curved section 41, and the other part is a straight section 42. When the rear pulley 11 is located in the straight section 42 of the guide rail 4, the end of the top cover 1 is raised upward, and its height is higher than the top of the water-blocking plate 21. When the rear pulley 11 moves backward to the curved section 41 of the guide rail 4, the top cover 1 rotates around its front hinge, and the end of the top cover 1 is pressed down and pressed against the top of the water-blocking plate 21 by the subsequent pulley 11.

[0018] When it is necessary to close the skylight 2, the motor 31 is started, driving the lead screw 32 to rotate. Since the nut is threadedly connected to the lead screw 32, the nut moves backward along the axial direction of the lead screw 32. The connecting plate 34 moves backward with the nut and pushes the front end of the top cover 1 backward. The rear pulley 11 of the top cover 1 rolls backward in the straight section 42 of the guide rail 4. When the rear pulley 11 moves to the curved section 41 of the guide rail 4, it is guided downward by the downward force of the curved section 41, and the rear pulley 11 gradually moves downward. The top cover 1 rotates around the front hinge, and the end presses down until the top cover 1 is completely covered on the top of the water-blocking plate 21, completing the sealing of the skylight 2. When the skylight 2 needs to be opened, the motor 31 rotates in reverse, driving the lead screw 32 to rotate in reverse. The nut moves forward along the axis of the lead screw 32, and the nut drives the connecting plate 34 to move forward synchronously. Since the front end of the top cover 1 is hinged to the connecting plate 34, the forward movement of the connecting plate 34 will pull the front end of the top cover 1 forward. At the same time, the rear pulleys 11 on the left and right sides of the top cover 1 roll forward in the straight section 42 of the guide rail 4. At this time, the top cover 1 maintains the posture of the end tilting upward, and its height is higher than the top of the water-blocking plate 21. As the connecting plate 34 and the rear pulleys 11 move, the top cover 1 gradually separates from the top of the water-blocking plate 21, thus realizing the opening of the skylight 2.

[0019] This utility model uses the hinged design of the curved section 41 at the end of the guide rail 4 and the top cover 1 to enable the end of the top cover 1 to rotate and press down when closed, avoiding the problem of leaving a gap to prevent interference between the top cover 1 and the water baffle 21. Structurally, it solves the defect of the traditional top cover not sealing well and reduces the possibility of rain and dust entering.

[0020] Furthermore, linear slide rails 35 are respectively provided on the left and right sides of the lead screw 32. The linear slide rails 35 are installed on the top of the container. Front pulleys 341 are respectively provided on the left and right sides of the connecting plate 34. The front pulleys 341 on the left and right sides of the connecting plate 34 are respectively rolled in the two linear slide rails 35. When the flat pushing mechanism 3 drives the connecting plate 34 to move back and forth, the front pulleys 341 on the left and right sides of the connecting plate 34 will roll back and forth synchronously in the corresponding linear slide rails 35, providing guidance for the movement of the connecting plate 34. This can limit the left and right deviation of the connecting plate 34 during the movement process, ensuring that the connecting plate 34 always moves stably along the axial direction of the lead screw 32, avoiding deviation in the fit between the top cover 1 and the guide slide rail 4 and the water-blocking plate 21 due to the deviation of the connecting plate 34, and improving the overall structural stability.

[0021] Furthermore, a sealing ring 22 is provided at the top of the water-blocking enclosure 21. When the top cover 1 is closed and pressed down to cover the top of the water-blocking enclosure 21, the bottom of the top cover 1 will be in close contact with the sealing ring 22 at the top of the water-blocking enclosure 21. The sealing ring 22 will undergo slight deformation under the pressure of the top cover 1, filling the tiny gap between the top cover 1 and the water-blocking enclosure 21, further enhancing the sealing performance between the top cover 1 and the water-blocking enclosure 21. Even if there are minor processing errors between the top cover 1 and the water-blocking enclosure 21, the sealing ring 22 can compensate for the gap through deformation, effectively preventing rainwater and dust from entering the interior of the container from the gaps, protecting the safety of the equipment inside the container, and further improving the overall sealing effect.

[0022] Furthermore, the motor 31 is a combined manual and electric motor. Under normal power supply conditions, the motor 31 can be started by electric control to realize the automatic opening and closing of the top cover 1. In case of special circumstances such as power failure or motor failure, it can be switched to manual mode. By manually operating the motor, such as shaking the handle, the lead screw 32 is rotated, thereby controlling the movement of the top cover 1. This avoids the problem that the top cover 1 cannot be operated when the power is off due to a single electric control mode, and ensures that the top cover 1 can always be opened and closed normally in complex environments such as field operations, meeting the needs of equipment use.

[0023] Furthermore, the nut is a ball nut that mates with the lead screw 32. Compared with ordinary sliding nuts, ball drives have lower frictional resistance, higher transmission efficiency, and can reduce the load on the motor 31. At the same time, they have less wear and a longer service life.

[0024] Furthermore, the front and rear ends of the lead screw 32 are connected to the top of the container via bearing seats 5. The bearings in the bearing seats 5 support the lead screw 32. When the motor 31 drives the lead screw 32 to rotate, the bearings can reduce the frictional resistance when the lead screw 32 rotates, and at the same time limit the radial runout of the lead screw 32, ensuring that the lead screw 32 always rotates stably along its own axis. This improves the stability of the lead screw 32 installation, avoids the lead screw 32 from shaking or deviating during rotation due to lack of support at both ends or unstable support, ensures the stability of the transmission of the flat push mechanism 3, and reduces component wear.

[0025] Specifically, the front end of the top cover 1 is connected to the connecting plate 34 via a hinge 6. The hinge structure of the hinge 6 allows the top cover 1 to rotate around the axis of the hinge 6, thereby realizing the hinge function between the top cover 1 and the connecting plate 34.

[0026] Furthermore, an accordion-style protective cover 7 is fitted onto the lead screw 32. The front end of the accordion-style protective cover 7 is fixedly connected to the top of the container, and the rear end is connected to the connecting plate 34. When the nut moves backward on the lead screw 32, the connecting plate 34 causes the accordion-style protective cover 7 to extend, thereby protecting the lead screw 32. When the nut moves forward on the lead screw 32, the accordion-style protective cover 7 shortens, without affecting the opening of the top cover 1.
