DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling readers to have a thorough understanding of one or more aspects of the utility model, and these aspects of the utility model can be realized even without these specific details.

[0024] See also Figures 1 to 3 The utility model provides a construction elevator flap door, and the technical solution is as follows:

[0025] The invention comprises a cage 1, a flap door 2 and a lifting door 3. A driving assembly for driving the cage 1 to move up and down is arranged on the top of the cage 1. The flap door 2 is rotatably installed at the bottom of the front side of the cage 1 through a rotating shaft 4. Two baffles 5 are symmetrically installed on the flap door 2. Two connecting plates 6 are symmetrically arranged on the upper section of the front side of the cage 1. Each connecting plate 6 is provided with a slide bar 7. Slide grooves 8 are arranged on the left and right sides of the lifting door 3, and the lifting door 3 moves up and down through the slide grooves 8 and the slide bar 7. Two card slots 9 are symmetrically arranged on the front side of the cage 1, and the baffles 5 and the card slots are connected to each other. Slot 9 cooperates, two driving motors 10 are symmetrically installed on the left and right outer walls of the cage 1, and cavities 24 are provided in the left and right side walls of the cage 1, and a winding box 11 is provided in each cavity 24, and a steel rope 12 is provided in each winding box 11, and each steel rope 12 passes through the slot 9 and is connected to the corresponding baffle 5. The output end of each driving motor 10 passes through the outer wall of the cage 1 and is connected to the corresponding winding box 11, and a winding assembly is provided in each winding box 11. The cage 1 is provided with a connecting assembly that cooperates with the flap door 2 to drive the lifting door 3 to move.

[0026] The construction workers can use the cage 1 of the elevator to transport building materials, tools and equipment from the ground to the high place of the construction site, and transport waste materials from the high place to the ground; during the process, the cage 1 moves up and down under the action of the driving component, and the cage 1 stops when it moves to the required floor. Since an electronic card for fixing the steel rope 12 is provided in the winding box 11, and it is electrically connected to the driving component, when the driving component stops, the electronic card releases the steel rope 12, and under the action of gravity, the flap door 2 moves in a circle with the rotating shaft 4 as the axis, until the flap door 2 is erected between the building and the cage 1, forming a passage for the staff and goods to pass through, avoiding the safety hazard of bumps and rollovers when the cart enters and exits the cage 1 due to the large gap between the building and the cage 1, thereby improving safety; at the same time, through the cooperation of the connecting component, the lifting door 3 is subjected to an upward pulling force, and through the cooperation of the slide slot 8 and the slide rod 7, the lifting door 3 moves upward synchronously to open the front exit of the entire cage 1;

[0027] When it is necessary to go to other floors, start the two driving motors 10. The driving motor 10 drives the winding assembly in the winding box 11 and the two steel ropes 12 through the output shaft to move the flap door 2 away from the building until the two baffles 5 on the flap door 2 are inserted into the corresponding slots 9. At the same time, due to gravity, the lifting door 3 moves downward, and cooperates with the restored flap door 2 to cover the passage on the front side of the cage 1, thereby ensuring the safety of construction workers and goods during the lifting process.

[0028] The winding assembly includes an outer ring 13, an inner ring 14 and a roller 15. The outer ring 13 is rotatably connected in the winding box 11, and the inner ring 14 is arranged in the outer ring 13. The output shaft of the driving motor 10 passes through the winding box 11, and the inner ring 14 is sleeved on the output shaft of the driving motor 10. Two right-angle grooves 25 are symmetrically provided in the center of the inner ring 14. The roller 15 is connected in each right-angle groove 25 through a limit spring 16. The steel rope 12 passes through the winding box 11 and is connected to the outer ring 13. In the process of the flap door 2 being flipped outward and erected between the building and the cage 1, the steel rope 12 is stretched under the drive of the flap door 2, and at the same time drives the winding box The outer ring 13 in 11 rotates, and since the roller 15 is not in contact with the outer ring 13 at this time, the inner ring 14 does not rotate accordingly, that is, it will not interfere with the movement of the flap door 2; when the drive motor 10 is started to retract the flap door 2, the output shaft of the drive motor 10 drives the inner ring 14 to rotate. During rotation, the roller is affected by the elastic force of the limit spring 16 and the centrifugal force, so that the roller 15 contacts the outer ring 13. While the inner ring 14 rotates, the outer ring 13 is driven to rotate at the same time through the roller 15, that is, the steel rope 12 is driven to be retracted into the winding box 11 until the flap door 2 is recovered.

[0029] The connecting component includes two support rods 17 symmetrically arranged on the left and right sides of the flap door 2, two transition wheels 18 are provided on the outer side walls on the left and right sides of the cage 1, and two guide wheels 19 are symmetrically provided on the top of the cage 1, and a connecting rope 20 is sleeved on each support rod 17. The connecting rope 20 is a highly wear-resistant galvanized steel wire rope, and each connecting rope 20 is wrapped around two transition wheels 18 and the corresponding guide wheel 19 to connect with the lifting door 3; the length of each connecting rope 20 is fixed, and the connecting rope 20 is always in a straight state by winding the connecting rope 20 around the two transition wheels 18 and the upper guide wheel 19. When the flap door 2 rotates, the lifting door 3 is synchronously lifted and lowered in cooperation with the two connecting ropes 20 to achieve the purpose of simultaneous opening and closing. It is only necessary to control the opening and closing of the flap door 2 to synchronously control the lifting and lowering of the lifting door 3, thereby improving efficiency and improving the efficiency of construction personnel and goods entering the cage 1.

[0030] One-way rotation dampers are provided at both ends of the rotating shaft 4; the one-way rotation dampers provide resistance to unilateral rotation. When the flap door 2 flips outward until it is connected to the cage 1 and the building, the one-way rotation damper acts as a decelerator, thereby reducing the rate at which the flap door 2 flips outward, preventing the flap door 2 from directly colliding with the building, reducing damage to the flap door 2 caused by the collision, and increasing the service life of the flap door 2; when the flap door 2 is restored, the one-way rotation damper does not provide resistance, and the flap door 2 can be easily recovered by driving the motor 10 and the steel rope 12.

[0031] The lifting door 3 is configured as a segmented linked lifting door 3; a single lifting door 3 goes straight up and down, which requires a longer connecting rope 20, and the pulling force of the connecting rope 20 will be increased during the process, increasing the risk of wear and breakage of the connecting rope 20. By configuring the segmented linked lifting door 3, a certain bending arc can be formed, which can reduce the length requirement of the connecting rope 20, and reduce the pulling force on the connecting rope 20 during the process, while reducing the space required for the movement of the lifting door 3, thereby improving convenience and safety.

[0032] The side of the lifting door 3 close to the cage 1 is arc-shaped, and the top of the front side of the cage 1 is arc-shaped; during the up and down movement of the lifting door 3, the fit between the lifting door 3 and the top of the front side of the cage 1 is increased, and the wear and consumption of the lifting door 3 and the top of the front side of the cage 1 are reduced, thereby increasing the service life of the lifting door 3.

[0033] The counterweight at the lower end of the lifting door 3 accounts for 50% of the weight of the entire lifting door 3; by increasing the counterweight at the lower end of the lifting door 3, when it is necessary to close the exit of the cage 1, the lower end of the lifting door 3 accounts for 50% of the weight of the entire lifting door 3, which can stably give the lifting door 3 a downward pulling force, avoiding the situation where the lifting door 3 stays at the top of the cage 1, and ensuring the stability of the opening and closing of the lifting door 3.

[0034] A slope 21 is provided at the end of the flap door 2 to facilitate construction workers to carry tools or goods in and out of the cage 1. Anti-slip stripes 22 are provided on the moving surface of the flap door 2; together with the baffle 5, they play an anti-slip interception role to avoid rollover during transportation, thereby further improving safety.

[0035] A removable buffer pad 23 is provided on the side of the flap door 2 away from the moving surface; when the flap door 2 flips outward and contacts the building, it plays a buffering role to prevent the flap door 2 from directly colliding with the building, and the impact force caused by the flap door 2 is damaged; and the buffer pad 23 is removable. When the buffer pad 23 is excessively worn, it can be removed and replaced to ensure the stability of the flap door 2.

[0036] A groove is provided on each baffle 5, a ball joint is provided in each groove, and each ball joint is connected to a corresponding steel rope 12; when the flap door 2 flips, the steel rope 12 will be driven to move, that is, there is a pulling force on the steel rope 12, and the connection between the steel rope 12 and the flap door 2 is prone to wear. A ball joint is provided to connect the steel rope 12. When the pulling force remains unchanged, the ball joint can automatically adjust the direction in the groove to avoid long-term friction between the steel rope 12 and the groove, thereby preventing the steel rope 12 from being damaged due to excessive friction.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
