Description

Technical Field

[0001] The utility model belongs to the technical field of building ventilation, in particular to a movable roof structure for a high-temperature workshop. Background Art

[0002] The production process of ceramsite sand requires the use of equipment such as a rotary kiln, dryer, and granulator. When the rotary kiln is operating, the ceramsite sand raw material enters from the kiln's rear end and continuously rolls toward the kiln's front end as the rotary kiln rotates. Inside the kiln, fuel such as pulverized coal is injected from the front end and burns, generating high temperatures. Workers exposed to high temperatures for extended periods of time are prone to heatstroke, dehydration, and heat exhaustion. Therefore, a good ventilation system is required in high-temperature workshops to promptly remove heat and harmful gases, maintain air circulation, and reduce temperature and humidity.

[0003] The existing ventilation method is a combination of natural ventilation and mechanical equipment ventilation. During natural ventilation, ventilation is generally carried out through doors and windows. Door and window ventilation mainly uses horizontal air flow to introduce fresh air from the outside and exhaust indoor air. However, since hot air rises in high-temperature workshops, the exhaust effect of hot air and dirty air at high altitudes is relatively unsatisfactory. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a movable roof structure for a high-temperature workshop.

[0005] The utility model provides a movable roof structure for a high-temperature workshop, comprising a main support frame and a secondary support frame, wherein both the main support frame and the secondary support frame are inverted V-shaped structures, and the secondary support frame is located on the top of the main support frame, a main baffle is laid on the main support frame, and a secondary baffle is laid on the secondary support frame, and a ventilation channel is reserved between the main baffle and the top of the main support frame;

[0006] Several cylinders are arranged in a straight line on the top of the main support frame along the length direction of the main support frame. The bottom of each cylinder is fixedly connected to the top of the main support frame, and the output end of each cylinder is connected to the middle of the auxiliary support frame. The cylinder is used to drive the auxiliary support frame to rise or fall so that the ventilation channel is opened or closed.

[0007] A further solution is that the main support frame includes two symmetrically arranged first support frames, and the side walls of the two first support frames are welded into an inverted V-shaped structure by angle steel;

[0008] The first support frame includes a plurality of main cross beams arranged side by side in a transverse direction, a plurality of main longitudinal beams are arranged longitudinally at the bottom of the main cross beams, and the main baffles are laid on the main cross beams and fixedly connected to the main cross beams.

[0009] A further solution is that the main crossbeam is an I-beam.

[0010] A further solution is that the auxiliary support frame includes two symmetrically arranged second support frames, and the side walls of the two second support frames are welded into an inverted V-shaped structure by angle steel;

[0011] The second support frame includes a plurality of secondary crossbeams arranged side by side in a transverse direction, a plurality of secondary longitudinal beams are arranged longitudinally at the bottom of the secondary crossbeams, and the secondary baffles are laid on the secondary crossbeams and fixedly connected to the secondary crossbeams.

[0012] A further solution is that rollers are provided on both sides of the main crossbeam, the two rollers are connected by a roller bracket, and the bottom of the roller bracket is rotatably connected to the roller;

[0013] A support rod is provided on the top of the roller bracket, the bottom of the support rod is connected to the roller bracket, and the top of the support rod is hinged to the secondary crossbeam through a hinge seat.

[0014] A further solution is that limit blocks are provided on both sides of the main beam to limit the position of the roller.

[0015] A further solution is that sealing plates extend outward from both sides of the auxiliary baffle, and the sealing plates are bent plates so that the edges of the sealing plates are lower than the auxiliary baffle and parallel to the auxiliary baffle.

[0016] A further solution is that side baffles are further provided on both sides of the secondary support frame, and the side baffles are fixedly connected to the secondary crossbeam.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This new roof structure utilizes a main support frame and a secondary support frame. A ventilation channel is reserved between the main baffle and the top of the main support frame. The height of the secondary support frame is adjusted by a cylinder to open or close the ventilation channel. Hot air from high-temperature workshops rises and is discharged through the ventilation channel, effectively removing hot and stale air from the room and achieving significant ventilation. In cold weather, the ventilation channel can be closed to maintain heat retention, making it suitable for natural ventilation and heat preservation in high-temperature workshops.

[0026] In order to make the purpose, technical solution, design method and advantages of the present invention more clear, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 1 As shown, the utility model provides a movable roof structure for a high-temperature workshop, including a main support frame and a secondary support frame 4, both of which are inverted V-shaped structures, and the secondary support frame 4 is located on the top of the main support frame, a main baffle 3 is laid on the main support frame, and a secondary baffle 5 is laid on the secondary support frame 4, and a ventilation channel 12 is reserved between the main baffle 3 and the top of the main support frame; a plurality of cylinders 7 are arranged in a straight line along the length direction of the main support frame on the top of the main support frame, and the bottom of each cylinder 7 is fixedly connected to the top of the main support frame, and the output end of each cylinder 7 is connected to the middle of the secondary support frame 4. In this embodiment, a cylinder support is provided at the bottom of the cylinder 7, and the cylinder support is evenly arranged on the top of the main support frame. The secondary support frame 4 is driven to rise or fall by the cylinder 7, so that the ventilation channel 12 is opened or closed. As shown Figure 5 As shown, when the cylinder 7 lifts the auxiliary support frame 4, the ventilation channel 12 is opened, and the hot air in the high-temperature workshop rises and is discharged through the ventilation channel 12, which can effectively discharge the hot air and dirty air in the room, and the ventilation effect is significant. When the ventilation channel 12 is closed, it can also achieve heat preservation in cold weather, which is suitable for natural ventilation and heat preservation in high-temperature workshops.

[0028] like Figure 3As shown, the main support frame includes two symmetrically arranged first support frames, and the side walls of the two first support frames are welded into an inverted V-shaped structure by angle steel; wherein, the first support frame includes a plurality of main crossbeams 1 arranged side by side horizontally, and a plurality of main longitudinal beams 2 are longitudinally arranged at the bottom of the main crossbeam 1, and the main baffle 3 is laid on the main crossbeam 1 and fixedly connected to the main crossbeam 1. In this embodiment, the main crossbeam 1 is an I-beam. The secondary support frame 4 includes two symmetrically arranged second support frames, and the side walls of the two second support frames are welded into an inverted V-shaped structure by angle steel; wherein, the second support frame includes a plurality of secondary crossbeams 13 arranged side by side horizontally, and a plurality of secondary longitudinal beams 14 are longitudinally arranged at the bottom of the secondary crossbeam 13, and the secondary baffle 5 is laid on the secondary crossbeam 13 and fixedly connected to the secondary crossbeam 13.

[0029] like Figure 2 As shown, to ensure the stability of the inverted V-shaped secondary support frame 4 during its ascent or descent, in this embodiment, rollers 9 are correspondingly disposed in the grooves on either side of the I-beam. The two rollers 9 are connected by a roller bracket 8, the bottom of which is rotatably connected to the rollers 9. A support rod 10 is disposed at the top of the roller bracket 9, the bottom of which is connected to the roller bracket 9, and the top of which is hinged to the secondary crossbeam 13 via a hinge seat 11. Limiting blocks 15 are disposed on both sides of the main crossbeam 1 to limit the position of the rollers 9. When the cylinder 7 lifts the secondary support frame 4, the rollers 9 roll obliquely upward along the grooves of the I-beam. When the secondary support frame 4 is lowered, the rollers 9 roll obliquely downward along the grooves of the I-beam until the rollers 9 abut against the limiting blocks 16.

[0030] Continue to refer to Figure 2 Sealing plates 6 extend outward from both sides of the secondary baffle 5. These plates are bent so that their edges are lower than and parallel to the secondary baffle 5. The design of the sealing plates 6 reduces the stroke of the cylinder 7 when closing the ventilation channel 12. Furthermore, when the secondary support frame 4 is raised, the air inlet or outlet at one end of the ventilation channel 12 is reduced, thereby accelerating the flow rate.

[0031] In order to prevent rainwater from entering the high temperature workshop, Figure 4 As shown, side baffles 16 are further provided on both sides of the secondary support frame 4 , and the side baffles 16 are fixedly connected to the secondary crossbeam 13 .
