Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a linkage mechanism for the door flapping panel of an intelligent construction elevator car. Background Technology

[0002] As a crucial safety protection device during equipment operation, the car door of a construction hoist directly affects the equipment's functionality and safety. Currently, most construction hoist car doors on the market adopt a single structural form, such as a swing door, a one-way sliding door, or a folding door. While these designs can basically meet the needs of personnel and material transportation on construction sites, they have many shortcomings in practical applications, especially in high-frequency use and complex construction environments, where their deficiencies become more pronounced.

[0003] A search revealed that patent number "CN215287625U" describes a "high-rise building construction hoist cage flip-up door platform. One end of the flip-up platform body is hinged to the bottom of the construction elevator's exit door. Protective railings are installed on both sides of the flip-up platform body. Pulleys are installed in the middle and top of the construction elevator. An upper door panel is vertically installed above the construction elevator's exit door. Vertical sliding grooves are installed on both sides of the upper part of the construction elevator's exit door. The upper door panel slides vertically within these grooves on both sides. One end of a traction rope is connected to the lower part of the upper door panel. The other end of the traction rope passes around the pulleys at the top and middle of the construction elevator and is fixed to the middle of the flip-up platform body. This platform can serve as a transportation channel for the construction hoist and also..." As a protective platform for construction hoists, it reduces the need for traditional operating platforms and minimizes safety hazards during demolition. Belonging to the field of building construction technology, its operation involves the upper door panel and the tilting platform body forming the elevator car door. When the tilting platform body is pushed to lie flat as a traveling platform, the upper door panel slides upwards via a traction rope, thus opening the elevator car door. However, existing car doors typically use a motor for lifting and gravity for descent. This new device requires active control of the upper door panel's up-and-down movement, resulting in a complex operating structure. Furthermore, directly controlling all car door movements necessitates a larger footprint for the power supply unit, increasing car weight, reducing lifespan, and increasing transportation risks. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent construction elevator car door linkage mechanism to solve the problems that directly controlling all the movements of the car door would require a larger footprint for the power supply device, which would further increase the weight of the car, reduce its lifespan, and increase transportation risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent construction elevator car door linkage mechanism, including a car and a car door installed thereon, the car door including an upper car door slidably connected to the car and a lower car door hinged to the car, and a motor for providing power to the upper car door is installed on the car;

[0006] The car is provided with a first pulley, a second pulley and a fixing block on both sides from top to bottom. The lower door of the car is provided with a third pulley on both sides. The bottom of the upper door of the car is fixedly connected to the first end of the steel cable. The end of the steel cable passes through the first pulley, the second pulley and the third pulley in sequence and is fixedly connected to the fixing block.

[0007] Preferably, the output end of the motor is equipped with a take-up roller, the take-up roller has a locking groove on its take-up shaft, a locking block is provided in the locking groove, and the locking groove and the locking block are connected by screws.

[0008] Preferably, a sling is provided between the locking groove and the locking block, and the other end of the sling passes through a roller set on the top of the car and is fixedly connected to the bottom of the upper door of the car.

[0009] Preferably, the suspenders are made of nylon.

[0010] Preferably, the two sides of the lower door of the car are hinged to the guardrail via a shaft, and the shaft is fixedly connected to the guardrail. A first gear is fixedly connected to the end of the shaft, a first conical-straight compound double gear meshes below the first gear, and a second conical-straight compound double gear meshes on one side of the first conical-straight compound double gear.

[0011] The car is hinged to the lower door via a second shaft, and the car is fixedly connected to the second shaft. A second gear is fixedly connected to the second shaft, and the second gear meshes with a second bevel-straight compound double gear for transmission.

[0012] Preferably, the outer side of the guardrail is provided with a first locking strip fixedly connected to the lower door of the car, and the outer wall of the lower door of the car is fixedly connected with a second locking strip.

[0013] Preferably, the length of the upper door of the car is two-thirds of the length of the car, the length of the lower door of the car is one-third of the length of the car, and the total weight of the lower door and the guardrail is less than the weight of the upper door of the car.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The motor drives the winding roller to rotate, which in turn drives the sling to lift or lower the upper door of the car. This causes the upper door to lift or lower the steel cable fixed at the bottom. The first, second, and third pulleys cause the lower door of the car to open or close synchronously. With the guardrail in place, when the lower door of the car opens or closes, the second gear, when fixed, forces the second conical-straight compound double gear to rotate. This, in turn, drives the first conical-straight compound double gear, which in turn drives the first gear, thereby opening and closing the guardrail. This forms a linkage structure between the motor, the upper door of the car, the lower door of the car, and the guardrail.

[0016] Second, by setting up the take-up roller, the sling can be placed in the locking groove, and then the locking block can be placed in the locking groove. The locking block is then fixed to the locking groove with screws to prevent the sling from coming off the take-up roller during use and causing danger.

[0017] Third, the first locking strip can prevent the guardrail from opening too wide, which could damage the linkage structure. The second locking strip can prevent the lower door of the car from opening too wide, which could damage the linkage structure. The weight of the lower door and guardrail can reduce the force required to open the upper door of the car, thus improving the operating efficiency and lifespan of the motor.

[0024] 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.

[0025] Please see Figure 1-5 As shown, this utility model provides a technical solution: an intelligent construction elevator car door linkage mechanism, including a car 1 and a car door installed thereon. The car door includes an upper car door 2 that is slidably connected to the car 1 and a lower car door 3 that is hinged to the car 1. A motor 4 for providing power to the upper car door 2 is installed on the car 1.

[0026] The car 1 is provided with a first pulley 51, a second pulley 52 and a fixing block 54 on both sides from top to bottom. The lower door 3 of the car is provided with a third pulley 53 on both sides. The bottom of the upper door 2 of the car is fixedly connected to the first end of the steel cable 6. The end of the steel cable 6 passes through the first pulley 51, the second pulley 52 and the third pulley 53 in sequence and is fixedly connected to the fixing block 54.

[0027] With the motor 4 in place, the motor 4 drives the winding roller 7 to rotate, which in turn drives the sling 73 to lift or lower the upper door 2 of the car, so that the upper door 2 of the car drives the steel cable 6 fixedly connected at the bottom to be lifted or lowered. Through the action of the first pulley 51, the second pulley 52 and the third pulley 53, the lower door 3 of the car opens or closes synchronously, forming a linkage structure.

[0028] Furthermore, a take-up roller 7 is installed at the output end of the motor 4. A locking groove 71 is provided on the take-up shaft of the take-up roller 7. A locking block 72 is provided in the locking groove 71. The locking groove 71 and the locking block 72 are connected by screws.

[0029] By setting the take-up roller 7, the sling 73 can be placed in the locking groove 71, and then the locking block 72 can be placed in the locking groove 71. The locking block 72 is then fixed to the locking groove 71 with screws to prevent the sling 73 from coming off the take-up roller 7 during use and causing danger.

[0030] Furthermore, a sling 73 is provided between the slotting groove 71 and the slotting block 72, and the other end of the sling 73 passes through the rollers set on the top of the car 1 and is fixedly connected to the bottom of the upper door 2 of the car.

[0031] Furthermore, the suspenders 73 are made of nylon.

[0032] Furthermore, the two sides of the lower door 3 of the car are hinged to the guardrail 13 via shaft 8, and shaft 8 is fixedly connected to the guardrail 13. A first gear 91 is fixedly connected to the end of shaft 8. A first conical-straight compound double gear 92 meshes below the first gear 91. A second conical-straight compound double gear 93 meshes on one side of the first conical-straight compound double gear 92.

[0033] The car 1 is hinged to the lower door 3 via shaft 2 10, and the car 1 is fixedly connected to shaft 2 10. A second gear 94 is fixedly connected to shaft 2 10, and the second gear 94 meshes with the second bevel-straight compound double gear 93 for transmission.

[0034] By setting up the guardrail 13, when the lower door 3 of the car is opened or closed, the second conical-straight compound double gear 93 can be forced to rotate by fixing the second gear 94, which in turn drives the first conical-straight compound double gear 92, drives the first gear 91, and thus drives the guardrail 13 to open and close.

[0035] Furthermore, a first locking strip 11 is fixedly connected to the lower door 3 of the car on the outer side of the guardrail 13, and a second locking strip 12 is fixedly connected to the outer wall of the lower door 3 of the car.

[0036] The first locking strip 11 can prevent the guardrail 13 from opening too wide, which could damage the linkage structure. The second locking strip 12 can prevent the lower door 3 of the car from opening too wide, which could damage the linkage structure.

[0037] Furthermore, the length of the upper door 2 is two-thirds of the length of the car 1, and the length of the lower door 3 is one-third of the length of the car 1. The total weight of the lower door 3 and the guardrail 13 is less than the weight of the upper door 2.

[0038] The weight of the lower door 3 and the guardrail 13 can reduce the force required to open the upper door 2, thereby improving the operating efficiency and lifespan of the motor 4.

[0039] Working principle: First, the intelligent construction elevator car door-flipping linkage mechanism is moved to the working position. In use, the first step is that the motor 4 drives the winding roller 7 to rotate, and the winding roller 7 winds up the sling 73, lifting the upper door 2 of the car. The second step is that while the upper door 2 of the car is lifted, the steel cable 6 connected to the upper door 2 of the car is loosened, so that the steel cable 6 changes direction through the first pulley 51, the second pulley 52 and the third pulley 53, and finally the lower door 3 of the car descends due to its weight. The third step is that while the lower door 3 of the car is opening, it drives the second conical straight compound double gear 93 to move. Since the second gear 94 meshed with the second conical straight compound double gear 93 cannot move, the second conical straight compound double gear 93 rotates, which in turn drives the first conical straight compound double gear 92, drives the first gear 91, and then drives the shaft 8 to rotate, which drives the guardrail 13 to open. This completes the linkage opening process of the intelligent construction elevator car door-flipping linkage mechanism.

[0040] When the doors need to be closed in a coordinated manner, the first step is to drive the winding roller 7 to rotate via the motor 4, which loosens the hoisting belt 73, causing the upper door 2 of the car to descend. The second step is that as the upper door 2 descends, because its weight is greater than that of the lower door 3, it causes the steel cable 6 to descend as well. The steel cable 6 changes direction via the first pulley 51, the second pulley 52, and the third pulley 53, ultimately lifting and closing the lower door 3. The third step is that as the lower door 3 closes, it moves the second conical-straight compound double gear 93. Since the second gear 94, which meshes with the second conical-straight compound double gear 93, cannot move, the second conical-straight compound double gear 93 rotates, which in turn drives the first conical-straight compound double gear 92, which in turn drives the first gear 91, which in turn drives the shaft 8 to rotate, causing the guardrail 13 to close. This completes the coordinated door closing process of an intelligent construction elevator car door-folding linkage mechanism.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
