FIG. 1 is a schematic structural view of the rolling door of the present invention;
fig. 2 is a schematic view of the installation structure of the reinforced support frame (5) and the support door (6).
Detailed Description
Referring to fig. 1-2, the cold-proof and warm-keeping device for the underground ramp entrance comprises a rolling door 2, a reinforcing and supporting frame body 5 and a supporting door 6, wherein the rolling door 2 is connected with a motor 1; the underground opening is provided with a track groove 3, and the rolling door 2 is driven by the motor 1 to lift in the track groove 3, so that the underground opening is opened or closed. The shutter door 2 is normally closed, and is opened when a vehicle or a person passes. Can effectively control cold air to enter the ramp. Because the air suction capacity of the underground slope tunnel mouth is very large, the rolling door 2 is deformed into an arc shape under the action of strong suction force, is pulled out from the tracks on the two sides and causes damage to surrounding vehicles and personnel. Therefore, a reinforcing safety matching measure is adopted for the rear part of the roller shutter door: a reinforcing support frame body 5 is provided. The reinforcing support frame body 5 comprises two longitudinal rods and a plurality of cross rods, the cross rods are arranged between the two longitudinal rods at equal intervals, one end of each cross rod is connected with one longitudinal rod, and the other end of each cross rod is connected with the other longitudinal rod. The vertical rod is made of square steel. The reinforcing support frame body 5 is installed on two sides of the underground opening, the reinforcing support frame body 5 is close to the rolling door 2, and the reinforcing support frame body 5 is located behind the rolling door 2 and is close to the inside of the slope way. The middle part of the reinforcing support frame body 5 is provided with a support door 6, the support door 6 is in a grid shape, and two ends of the support door 6 are respectively connected with a longitudinal rod. The reinforcing support frame body 5 is provided with a plurality of pulleys 4, and the plurality of pulleys 4 are positioned at the joint of the reinforcing support frame body 5 and the support door 6. A set of pulleys are respectively installed on two sides inside the reinforcing support frame body and two sides of the passing support door from top to bottom, and each set of 12 wheels facilitate the lifting of the roller shutter under the state of huge suction and are not easy to wear. The two sets of pulleys 4 are respectively parallel to the track grooves 3. Vehicles and personnel need to pass through the middle of the reinforcing and supporting frame bodies on the two sides of the underground opening, and the large-span space in the middle of the reinforcing and supporting frame body supports the huge suction force of the rolling door through the supporting net rack. The support door 6 serves the purpose of supporting the net rack and providing access. The supporting door 6 can bear all the forces of the rolling door in the running state and the closing state in the closing state, so that the rolling door is ensured not to deform; when the vehicle or the person needs to pass, the rolling door 2 is opened, and the supporting door 6 is opened to provide the passing.
When the device is used, when a vehicle or a person needs to pass, the roller shutter door motor 1 is started, the roller shutter door 2 rises and runs in the track groove 3 of the roller shutter door, the roller shutter door stops running to the top end of the device, and the supporting door 6 is opened to allow the vehicle or the person to pass. After the passage is finished, the supporting door 6 is closed, the motor 1 of the rolling door is opened, the rolling door 2 descends in the track groove 3 to run, and the rolling door stops when running to the bottom end of the device. In the operation process, the reinforcing support frame body 5 at the rear part of the roller shutter door supports all large suction force during the lifting and operation of the roller shutter. The support door 6 prevents the rolling door from being changed into an arc shape by suction force, being pulled out from the rails at both sides, and further causing damage. The pulley 4 is convenient for the rolling screen to take off and land under the condition of receiving huge suction force, and is not easy to damage.
Example 1
The electric aluminum alloy rolling door with the length of 6 meters and the height of 5 meters is in a closed state under normal conditions, and the rolling door is opened when vehicles or people pass. Behind the roller shutter door, two groups of reinforcing support frames which are formed by phi 50 square steel and have the length of 1 meter and the height of 5 meters are arranged at the two sides close to the cave entrance wall. The upper part and the lower part of the reinforcing support frame body are fixed on the wall of the underground opening by using expansion screws to support the whole stress of the rolling door. A passing supporting door with the length of 4 meters and the height of 4 meters is arranged in the reinforcing and supporting frame body. And 3, a group of pulleys are respectively installed on two sides inside the reinforcing support frame body and two sides of the passing support door from top to bottom, and each group of 12 wheels is convenient for the rolling curtain to take off and land conveniently under the state of receiving huge suction and is not easy to wear. The cold wind prevention effect of the road surface of the slope is good, and the phenomenon of icing of the road surface is avoided.
