Description

Technical Field

[0001] This utility model relates to the field of construction elevators, and in particular to a construction elevator flip-up device. Background Technology

[0002] In the construction industry, construction elevators are key equipment for the vertical transportation of personnel and materials. Their safety and efficiency directly affect the progress and quality of the entire project. Among them, the flip-up device between the construction elevator and the floor platform plays an important connecting role, ensuring the safe passage of personnel and materials between the elevator and the floor.

[0003] A flip-plate linkage device for construction elevator doors, disclosed in Publication No. CN220618062U, includes a construction elevator cage. A flip-plate is hinged to the bottom plate of the construction elevator cage. When the construction elevator door is opened, the flip-plate is linked to the elevator door, avoiding the need for personnel to manually pull the flip-plate lever after opening the construction elevator door. However, although the device can realize the synchronous opening and closing of the elevator door and the flip-plate, it does not have a reinforcement function. During long-term use, the flip-plate is prone to bending, deformation, or even damage. Once the flip-plate is damaged, it will not only affect normal use, but also cause gaps between the elevator and the floor, increasing the risk of personnel and materials falling and affecting the safety of use.

[0004] Therefore, it is necessary to design a construction elevator flap device that can simultaneously open and close the elevator door and flap, extend a reinforcing plate for reinforcement, and then retract it to prevent the flap from bending or being damaged, reduce the occurrence of accidents, and ensure safe and convenient use. Utility Model Content

[0005] To overcome the shortcomings of current devices that lack reinforcement capabilities, causing the flap to bend, deform, or even break during long-term use, which not only affects normal operation but also creates gaps between the elevator and the floors, increasing the risk of people and materials falling and compromising safety, this invention provides a construction elevator flap device that can simultaneously open and close the elevator door and flap while extending a reinforcing plate for reinforcement and then retracting it. This prevents the flap from bending or breaking, reduces the occurrence of accidents, and provides a safe and convenient construction elevator flap device.

[0006] A construction elevator flip-up device includes a standard elevator, a connecting rod, a rotating block, a flip-up plate, an elevator door, a mounting block, a guide block, upper small rope pulleys, a connecting block, an opening component, and a reinforcing component. The standard elevator has a connecting rod connected to its lower right side, with rotating blocks rotatably connected to both the front and rear ends of the connecting rod. A flip-up plate is connected between the rotating blocks. Two mounting blocks are connected to the lower right side of the standard elevator, and two guide blocks are connected to the upper right side of the standard elevator. An elevator door is slidably connected between the guide blocks. All mounting blocks are in contact with the elevator door. Two upper small rope pulleys are rotatably connected to the inner side of the upper right side of the standard elevator. Two connecting blocks are connected to the left side of the flip-up plate. The standard elevator is equipped with an opening component for simultaneously opening the elevator door and the flip-up plate. A reinforcing component is provided between the standard elevator and the flip-up plate to prevent the flip-up plate from bending.

[0007] To further explain, it also includes railings; railings are connected to the left sides of both the front and rear sides of the flip panel.

[0008] To further clarify, all railings are U-shaped.

[0009] To further explain, the opening assembly includes a first intermediate small rope sheave, a second intermediate small rope sheave, a motor, and a support plate. In a typical elevator, two support plates are connected to the inner side of the middle section. The first intermediate small rope sheave is rotatably connected to the side of the support plates that are far apart from each other, while the second intermediate small rope sheave is rotatably connected to the side of the support plates that are close together. The first intermediate small rope sheave is connected to the second intermediate small rope sheave on the same side. Steel wire ropes are wound around both the first and second intermediate small rope sheaves. The steel wire ropes on the first intermediate small rope sheaves are connected to the connecting block on the same side. The steel wire ropes on the second intermediate small rope sheaves pass over the upper small rope sheave on the same side and are connected to the elevator door. A motor is connected to each support plate. The motor and processor are electrically connected via a control module. The output shaft of each motor is connected to the first intermediate small rope sheave on the same side.

[0010] To further clarify, the first intermediate small rope pulley and the second intermediate small rope pulley have the same specifications.

[0011] To further explain, the reinforcement components include a reinforcing plate, springs, and limit blocks. The reinforcing plate is slidably connected to the lower part of the ordinary elevator, and multiple springs connect the reinforcing plate to the ordinary elevator. A limit block is connected to the upper left side of the flip plate.

[0012] The beneficial effects of this utility model are as follows: By rotating the first and second intermediate small rope wheels, the steel wire rope is wound up or unwound, thereby enabling the flap and elevator door to open or close simultaneously. When the flap opens or closes, the reinforcing plate moves to extend and reinforce or retracts, so that the reinforcing plate can extend to reinforce and retract simultaneously when the elevator door and the flap open and close, thus avoiding bending or damage to the flap, reducing the occurrence of accidents, and making it safe and convenient to use.

Detailed Implementation

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] A construction elevator flip-up device, such as Figures 1-4 As shown, the elevator includes a standard elevator 1, a connecting rod 2, a rotating block 3, a flap 4, an elevator door 5, a mounting block 6, a guide block 7, an upper small rope pulley 8, a railing 9, a connecting block 10, an opening component, and a reinforcing component. The standard elevator 1 is connected to the lower right of the connecting rod 2. The front and rear parts of the connecting rod 2 are rotatably connected to the rotating blocks 3. The flap 4 is connected between the rotating blocks 3. The lower right side of the standard elevator 1 is connected to the front and rear mounting blocks 6. The upper right of the standard elevator 1 is connected to the front and rear guide blocks 7. The elevator door 5 is slidably connected between the guide blocks 7. The mounting blocks 6 are all in contact with the elevator door 5. The upper right inner side of the standard elevator 1 is rotatably connected to the front and rear upper small rope pulleys 8. The left side of the front and rear parts of the flap 4 are both connected to the railings 9 for protection. The railings 9 are all U-shaped. The left side of the flap 4 is connected to the front and rear connecting blocks 10. The standard elevator 1 is equipped with an opening component for simultaneously opening the elevator door 5 and the flap 4. The standard elevator 1 and the flap 4 are equipped with a reinforcing component to prevent the flap 4 from bending.

[0020] like Figure 4As shown, the opening assembly includes a first intermediate small rope pulley 11, a second intermediate small rope pulley 12, a motor 13, and a support plate 14. Two support plates 14 are connected to the inner side of the middle section of the ordinary elevator 1. The first intermediate small rope pulley 11 is rotatably connected to the side of the support plates 14 that is far apart from each other, and the second intermediate small rope pulley 12 is rotatably connected to the side of the support plates 14 that is close to each other. The first intermediate small rope pulley 11 is connected to the second intermediate small rope pulley 12 on the same side. The first intermediate small rope pulley 11 and the second intermediate small rope pulley 12... Steel wire ropes are wound around the small rope pulleys 12. The steel wire ropes on the first small rope pulley 11 are all connected to the connecting block 10 on the same side. The steel wire ropes on the second small rope pulley 12 are all wrapped around the upper small rope pulley 8 on the same side and connected to the elevator door 5. The first small rope pulley 11 and the second small rope pulley 12 have the same specifications. Motors 13 are connected to the support plate 14. The motors 13 and the processor are electrically connected through the control module. The output shafts of the motors 13 are all connected to the first small rope pulley 11 on the same side.

[0021] like Figure 3 As shown, the reinforcement assembly includes a reinforcing plate 15, springs 16 and limiting blocks 17. The reinforcing plate 15 is slidably connected to the lower part of the ordinary elevator 1. Four springs 16 are connected between the reinforcing plate 15 and the ordinary elevator 1. The limiting block 17 is connected to the upper left side of the flip plate 4.

[0022] This device can be used when a construction elevator is needed for material or personnel transportation. A standard elevator 1 is used to transport materials and personnel to the appropriate floor. The processor, via the control module, starts motor 13, which drives the first intermediate pulley 11 to rotate, causing the wire rope to wind up. This pulls the elevator door 5 along the guide block 7 to open, causing the upper pulley 8 to rotate. Simultaneously, the second intermediate pulley 12 rotates, causing the corresponding wire rope to unwind. This causes the flap 4 to rotate and open, driving the rotating block 3 to rotate along the connecting rod 2, thus rotating the connecting block 10. This allows the elevator door 5 and flap 4 to open simultaneously. The first and second intermediate pulleys 11 are of the same specifications. As the flap 4 rotates and opens, the spring 16 rebounds, causing the reinforcing plate 15 to move and unfold, contacting the limiting block 17 for reinforcement. The materials are then removed, and personnel are transported. Step out of the ordinary elevator 1, walk along the flip-up plate 4 to the floor, and use the U-shaped railings 9 for protection. After the materials are removed, the motor 13 reverses its operation, causing the first intermediate small rope pulley 11 to rotate in the opposite direction, releasing the steel wire rope. Under the action of gravity, the elevator door 5 moves and closes, causing the upper small rope pulley 8 to rotate in the opposite direction. At the same time, it drives the second intermediate small rope pulley 12 to rotate in the opposite direction, causing the corresponding steel wire rope to wind up. This causes the flip-up plate 4 to rotate and close, driving the rotating block 3 to rotate in the opposite direction, thus achieving simultaneous closing of the elevator door 5 and the flip-up plate 4. As the flip-up plate 4 rotates and closes, it compresses the reinforcing plate 15 to move and reset, compressing the spring 16. This allows the elevator door 5 and the flip-up plate 4 to open and close simultaneously. The reinforcing plate 15 extends for reinforcement and then retracts, preventing the flip-up plate 4 from bending or being damaged, reducing the occurrence of accidents, and ensuring safe and convenient use. Then, the ordinary elevator 1 can be driven to descend.
