Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a construction external elevator and a non-standard floor line connection device and its construction method. Background Technology

[0002] During building construction, it is necessary to first build an external elevator to facilitate the vertical transportation of personnel and materials during high-rise construction.

[0003] When construction elevators encounter high-rise or super high-rise buildings, and when there are non-standard floors with structural lines, the elevator doors cannot be installed close to the structure. Due to the structural lines, there is a distance of more than 10cm between the elevator and the construction elevator, which results in a large gap between the elevator car and the building itself.

[0004] The gap between the elevator car and the building poses a significant safety hazard during construction. On the one hand, construction workers are at risk of falling through the gap, and on the other hand, construction materials may fall through the gap.

[0005] Therefore, this invention proposes a construction external elevator and a non-standard floor line connection device and its construction method. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a construction external elevator and a construction method for connecting non-standard floor lines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A connection device between a construction elevator and non-standard floor lines is disclosed. This device is installed inside the elevator car and specifically includes a suspension bridge structure located at the elevator car door and a control cabinet located inside the elevator car for controlling the suspension bridge structure.

[0009] The suspension bridge structure includes a guardrail, a support frame, and a tread. The guardrail is fixed to one outer wall of the support frame, and the tread is rotatably connected to the other outer wall of the support frame via a pivot. A connecting shaft is rotatably connected to the inner wall of the end of the support frame. The connecting shaft is fixed to the interior floor of the external elevator car via a fixing bracket. The suspension bridge structure also includes a driver for controlling the rotation of the support frame relative to the connecting shaft.

[0010] Preferably, a second bevel gear is fixed to the outer wall of the connecting shaft, and a first bevel gear is fixed to the outer wall of the end of the rotating shaft, with the first bevel gear and the second bevel gear meshing with each other.

[0011] Furthermore: the inner wall of the pedal is slidably fitted with an extension plate, and a rod penetrating the pedal is provided on one side of the extension plate. A sleeve block is movably sleeved on the outer wall of the rod, and a locking nut is threadedly connected to the outer wall of one of the rods.

[0012] Based on the aforementioned scheme: the outer wall of the pedal is provided with multiple grooves, and the bottom of the sleeve block is provided with locking teeth that engage with the grooves.

[0013] A better option among the aforementioned solutions is that the bottom of the pedal is provided with strain gauge 1 and strain gauge 2 that are perpendicular to each other, and at least one set of strain gauge 1 and strain gauge 2 are arranged.

[0014] As a further embodiment of the present invention: a press signal switch is fixed on the bottom outer wall of the pedal, a ramp is rotatably connected to the other outer wall of the pedal via a second rotating shaft, a micro motor is fixed to the side wall of the pedal by bolts, and the output shaft of the micro motor is connected to the end of the second rotating shaft via a coupling.

[0015] Meanwhile, the control cabinet includes a cabinet box, a display screen and a control keyboard located on the outer side of the cabinet box.

[0016] As a preferred embodiment of the present invention: a sleeve is provided on the other side of the cabinet, and a fixing plate is fixed to the inner wall of the external elevator car by anchor bolts, and a sleeve that cooperates with the hook is provided on the outer wall of the fixing plate.

[0017] Meanwhile, the cabinet contains a central processing unit, controller, signal receiver and communicator. The controller is connected to the driver, micro motor and display. The signal receiver is electrically connected to the communicator, press signal switch, strain gauge one, strain gauge two and control keyboard.

[0018] A construction method for connecting an external construction elevator with a non-standard floor line installation device includes the following steps:

[0019] S1: Loading, loading the construction personnel and materials into the external elevator car, and moving the external elevator car to reach the required height;

[0020] S2: Extended bridging. When the corresponding height is reached, the door of the external elevator car opens, and the driver drives the bracket to rotate relative to the connecting shaft, so that the bracket and the guardrail gradually rotate outward from the vertical state to the horizontal state, and the pedal rotates and unfolds relative to the bracket.

[0021] S3: Unloading. After the pedals and guardrails on both sides are unfolded, the pedals can cover the gaps, and construction workers can walk on the pedals and carry materials.

[0022] S4: Safety monitoring. During use, strain gauge one and strain gauge two can sense the deformation of the pedal. When abnormal deformation is detected, use will be stopped immediately.

[0023] S5: Remote control. The communicator can establish a communication connection with external communicable devices to achieve remote control.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. This invention, by setting up a suspension bridge structure, utilizes a footboard to cover the gap, thereby solving the safety hazards caused by the gap. At the same time, the footboard can be rotated and stored relative to the support until it is parallel to the guardrail, which can reduce the space occupied during storage. Furthermore, the rotation of the support and the footboard are connected through bevel gear one and bevel gear two, and can be jointly driven by the same driver.

[0026] 2. The present invention, by setting up a pedal and an extension plate, can achieve different support size extensions. On the other hand, the pedal and extension plate are modularly set up, forming a self-contained unit, which is convenient for disassembly and assembly and use.

[0027] 3. The present invention, by setting strain gauge one and strain gauge two, can sense the deformation of the pedal, thereby monitoring abnormal deformation caused by excessive load and increasing the safety of use.

[0028] 4. This invention, by setting up components such as a press signal switch and a ramp, can, on the one hand, block construction personnel and materials when the other end of the pedal is not reliably supported, thereby increasing safety; on the other hand, when the ramp is released from obstruction, it can also guide trolley-type material loads to climb the slope.

[0029] 5. This invention, by setting up a control cabinet, can realize electrical control while also realizing remote control function through a communicator. In addition, by setting up hooks and sleeves to fix the cabinet, the ease of disassembly and assembly of the entire control cabinet is increased. Attached Figure Description

[0045] In addition, the term "multiple" should mean two or more.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Example 1:

[0048] A device for connecting an external construction elevator to non-standard floor lines, such as... Figures 1-8 As shown, it is installed inside the external elevator car 1, specifically including a suspension bridge structure 3 installed at the door opening of the external elevator car 1 and a control cabinet 2 installed inside the external elevator car 1 for controlling the suspension bridge structure 3.

[0049] The suspension bridge structure 3 includes a guardrail 4, a support 5, and a step 9. The guardrail 4 is fixed to one outer wall of the support 5. The step 9 is rotatably connected to the other outer wall of the support 5 via a pivot 8. A connecting shaft 6 is rotatably connected to the inner wall of the end of the support 5. The connecting shaft 6 is fixed to the interior floor of the external elevator car 1 via a fixing frame 7. The suspension bridge structure 3 also includes a driver for controlling the rotation of the support 5 relative to the connecting shaft 6. In this embodiment, the specific type of driver is not limited. It can be a drive motor, a drive hydraulic rod, or other structures, as long as it can drive the support 5 to rotate from a vertical position to a horizontal position. All of the above are existing technologies, and this embodiment has not made any creative effort on them, so they will not be described in detail.

[0050] A bevel gear 11 is fixed to the outer wall of the connecting shaft 6, and a bevel gear 10 is fixed to the outer wall of the end of the rotating shaft 8. The bevel gear 10 and the bevel gear 11 mesh with each other.

[0051] When this device is in use, after reaching the corresponding height, the door of the external elevator car 1 opens, and the driver drives the bracket 5 to rotate relative to the connecting shaft 6, so that the bracket 5 and the guardrail 4 gradually rotate from a vertical state to a horizontal state. During this period, due to the meshing of bevel gear 10 and bevel gear 21, the rotating shaft 8 drives the pedal 9 to rotate, so that the pedal 9 rotates from a state parallel to the guardrail 4 to a vertical state. After both sides of the pedal 9 and the guardrail 4 are unfolded, the pedal 9 can cover the gap, and construction personnel can walk and carry materials through the pedal 9.

[0052] This device, by setting up a suspension bridge structure 3, can cover the gap using a pedal 9, thereby solving the safety hazards caused by the gap. At the same time, the pedal 9 can be rotated and stored relative to the support 5 until it is parallel to the guardrail 4, which can reduce the space occupied when stored. Meanwhile, the support 5 and the rotation of the pedal 9 are connected through bevel gear 10 and bevel gear 21, and can be jointly driven by the same driver.

[0053] To address the expansion problem; such as Figure 4 , 5 As shown, an extension plate 12 is slidably fitted on the inner wall of the pedal 9. A rod 13 that passes through the pedal 9 is provided on one side of the extension plate 12. A sleeve block 14 is movably sleeved on the outer wall of the rod 13. A locking nut 15 is threadedly connected to the outer wall of one of the rods 13.

[0054] The outer wall of the pedal 9 is provided with multiple grooves 17, and the bottom of the sleeve block 14 is provided with locking teeth 16 that engage with the grooves 17.

[0055] When different gap sizes or different support lengths are required, the extension plate 12 can be pulled outwards to the desired position, and then the locking nut 15 can be tightened to lock the position by the engagement of the locking teeth 16 and the groove 17.

[0056] This device, by setting up the pedal 9 and the extension plate 12, can achieve different support size extensions. On the other hand, the pedal 9 and the extension plate 12 are modularly set up, forming a self-contained unit, which is convenient for disassembly and use.

[0057] To address security issues; such as Figure 6 As shown, the bottom of the pedal 9 is provided with strain gauge 19 and strain gauge 20 that are perpendicular to each other, and at least one set of strain gauge 19 and strain gauge 20 are arranged.

[0058] By setting strain gauge 19 and strain gauge 20, the deformation of pedal 9 can be sensed, thereby monitoring abnormal deformation caused by excessive load and increasing the safety of use.

[0059] A press signal switch 18 is fixed to the bottom outer wall of the pedal 9. A ramp 21 is rotatably connected to the other outer wall of the pedal 9 via a rotating shaft 22. A micro motor 23 is fixed to the side wall of the pedal 9 by bolts. The output shaft of the micro motor 23 is connected to the end of the rotating shaft 22 via a coupling.

[0060] When the other end of the pedal 9 is not reliably supported, the pressing signal switch 18 is not squeezed, and the ramp 21 is in a vertical state, which can block the movement of construction personnel. As the pedal 9 continues to rotate and expand until the bottom of the other end of the pedal 9 is supported, the pressing signal switch 18 is also squeezed by the force, generating a closing signal. Then the micro motor 23 starts and drives the rotating shaft 22 to rotate, so that the ramp 21 rotates to the state where the other end contacts the external elevator car 1, releasing the obstruction. At the same time, it can also guide the loading of trolley-type materials to climb the ramp.

[0061] This device, by setting up components such as a press signal switch 18 and a ramp 21, can, on the one hand, block construction personnel and materials when the other end of the pedal 9 is not reliably supported, thereby increasing safety; on the other hand, it can also guide trolley-type material loads to climb the slope when the ramp 21 is released from obstruction.

[0062] To solve control problems; such as Figure 1 As shown, the control cabinet 2 includes a cabinet box 27, a display 28 and a control keyboard 29 disposed on the outer side of the cabinet box 27, and a sleeve 26 disposed on the other side of the cabinet box 27. The inner side wall of the external elevator car 1 is fixed with a fixing plate 24 by anchor bolts, and the outer wall of the fixing plate 24 is provided with a sleeve 26 that cooperates with the hook 25.

[0063] The cabinet 27 contains a central processing unit, a controller, a signal receiver, and a communicator. The controller is connected to the driver, the micro motor 23, and the display 28. The signal receiver is electrically connected to the communicator, the push signal switch 18, the strain gauge 19, the strain gauge 20, and the control keyboard 29.

[0064] The signal receiver can accept signals from the push signal switch 18, strain gauge 19, strain gauge 20, and control keyboard 29, and then send them to the central processing unit for processing. The central processing unit then generates corresponding control commands, which are then used by the controller to control the driver, micro motor 23, and display 28 to perform the corresponding actions.

[0065] The communicator can establish a communication connection with external communicable devices to achieve remote control.

[0066] This device, by setting up a control cabinet 2, can realize electrical control and also realize remote control function through a communicator. In addition, by setting up hooks 25 and sleeves 26 to fix the cabinet 27, the ease of disassembly and assembly of the entire control cabinet 2 is increased.

[0067] In this embodiment, when the corresponding height is reached, the door of the external elevator car 1 opens, and the driver drives the bracket 5 to rotate relative to the connecting shaft 6, thereby causing the bracket 5 and the guardrail 4 to gradually rotate from a vertical state to a horizontal state. During this period, due to the meshing of bevel gear 10 and bevel gear 2 11, the rotating shaft 8 drives the pedal 9 to rotate, causing the pedal 9 to rotate from a state parallel to the guardrail 4 to a vertical state. After both sides of the pedal 9 and the guardrail 4 are extended, the pedal 9 can cover the gap, allowing construction personnel to walk and carry materials. When different gap sizes or different support lengths are required, the extension plate 12 can be pulled outwards. After reaching the desired position, the locking nut 15 is tightened, and the locking teeth 16 and the groove 17 are engaged to achieve locking. When the other end of the pedal 9 is not reliably supported, the signal switch 1 is pressed. When the ramp 21 is not compressed, it is in a vertical position, which can block the movement of construction personnel. As the pedal 9 continues to rotate and expand until the bottom of the other end of the pedal 9 is supported, the push signal switch 18 is also compressed by the force, generating a closing signal. Then the micro motor 23 starts and drives the rotating shaft 22 to rotate, so that the ramp 21 rotates to the state where the other end contacts the external elevator car 1, releasing the obstruction. At the same time, it can also guide the loading of trolley-type materials to climb. Meanwhile, the signal receiver can receive signals from the push signal switch 18, strain gauge 19, strain gauge 20, and control keyboard 29, and then send them to the central processor for processing, and then generate corresponding control commands. The controller controls the driver, micro motor 23 and display 28 to perform corresponding executions. The communicator can establish a communication connection with external communicable devices to realize remote control.

[0068] Example 2:

[0069] A construction method for connecting an external elevator to a non-standard floor line, such as... Figures 1-8 As shown, it includes the following steps:

[0070] S1: Loading, loading the construction personnel and materials to be transported into the external elevator car 1, and moving the external elevator car 1 to reach the required height;

[0071] S2: Extended bridging. When the corresponding height is reached, after the door of the external elevator car 1 is opened, the driver drives the bracket 5 to rotate relative to the connecting shaft 6, so that the bracket 5 and the guardrail 4 gradually rotate from the vertical state to the horizontal state, and at the same time the pedal 9 rotates and unfolds relative to the bracket 5.

[0072] S3: Unloading. After both sides of the pedals 9 and guardrails 4 are unfolded, the pedals 9 can cover the gaps, and construction workers can walk and carry materials through the pedals 9.

[0073] S4: Safety monitoring. During use, strain gauge 19 and strain gauge 20 can sense the deformation of pedal 9. When abnormal deformation is detected, use will be stopped immediately.

[0074] S5: Remote control. The communicator can establish a communication connection with external communicable devices to achieve remote control.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
