Description

Technical Field

[0001] This application relates to the field of elevators, and in particular to a device for controlling the parallel operation of different elevator models. Background Technology

[0002] Currently, with the increase in high-rise buildings, these buildings are usually equipped with multiple elevators, which often come from different brands and manufacturers. Due to differences in technical standards, the control systems of elevators from different brands are difficult to control in parallel, which limits the overall efficiency and service quality of the elevator system.

[0003] Currently, most methods for achieving parallel operation of elevators are limited to elevators of the same brand or compatible protocols. They rely on dedicated parallel controllers to coordinate elevator operation. The basic elevator system includes at least: an internal elevator selection panel (inside the elevator car), an external elevator call panel (located on each floor of the building), and an elevator control cabinet. The internal and external elevator call panels are connected to the elevator control cabinet via cables, transmitting up / down and stop signals to the control cabinet. The elevator control cabinet transmits door opening signals to the control panel, and the control cabinet controls the motor to move the elevator up / down and stop at a specific floor.

[0004] Existing parallel control schemes cannot effectively solve the problem of collaborative operation of heterogeneous elevators. In particular, when it comes to the parallel operation of elevators from different brands, the independent control systems and communication protocols of each elevator make it difficult to achieve real-time and efficient scheduling and management, which in turn affects passenger experience and energy efficiency. Utility Model Content

[0005] The purpose of this application is to address the problem that existing parallel control schemes proposed in the background art cannot effectively solve the problem of collaborative operation of heterogeneous elevators, especially when it involves parallel operation of elevators of different brands. Due to their independent control systems and communication protocols, it is difficult to achieve real-time and efficient scheduling and management, which in turn affects passenger experience and energy efficiency. This application provides a device for controlling parallel operation of elevators of different models.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A device for controlling the parallel operation of different elevator models includes an elevator parallel control box, a door installed on the elevator parallel control box, a heat dissipation mechanism installed on the elevator parallel control box, a dust removal mechanism installed on the elevator parallel control box, an A control box electrically connected to the elevator parallel control box, a B control box electrically connected to the elevator parallel control box, an A call board electrically connected to the elevator parallel control box, a B call board electrically connected to the elevator parallel control box, an A camera electrically connected to the elevator parallel control box, and a B camera electrically connected to the elevator parallel control box.

[0008] By adopting the above technical solution, call panel A or call panel B sends a signal to the elevator parallel control box. Camera A or camera B in elevator A or elevator B transmits a signal to the elevator parallel control box. The signal includes the elevator's running direction and the number of floor options on the elevator's selection panel. After comprehensive judgment, the elevator parallel control box sends a signal to control box A or control box B, causing the nearest elevator that is not fully loaded to stop at the corresponding floor. This allows elevators of different brands to be connected in parallel, and suitable elevators to be arranged to stop at the corresponding floors, thereby improving the overall operating efficiency and service level of the elevator system.

[0009] Furthermore, the heat dissipation mechanism includes an air inlet chamber fixed to the bottom of the elevator parallel control box, an air outlet chamber fixed to the top of the elevator parallel control box, the air inlet chamber and the air outlet chamber being connected to the elevator parallel control box, an air inlet fan fixed inside the air inlet chamber, an air outlet fan fixed inside the air outlet chamber, and a protective net fixed on the air outlet chamber, the protective net corresponding to the air outlet fan.

[0010] By adopting the above technical solution, an intake fan draws outside air into the elevator parallel control box, and an exhaust fan draws the air out of the elevator parallel control box, thereby reducing the operating temperature inside the elevator parallel control box and reducing the possibility of excessive temperature affecting the normal operation of electrical components.

[0011] Furthermore, partition plates are fixed between the air outlet chamber, the air inlet chamber, and the elevator parallel control box.

[0012] By adopting the above technical solution, the air intake chamber and the air outlet chamber are separated by a partition plate, so that foreign objects can enter the air intake chamber and the air outlet chamber from the elevator parallel control box during routine maintenance.

[0013] Furthermore, several air guide plates are fixed inside the air intake chamber, and these air guide plates are arranged in a stepped manner.

[0014] By adopting the above technical solution, when the air intake fan blows air into the air intake chamber, it blows directly onto the air guide plate, thereby allowing the air to be blown into the elevator parallel control box and increasing the airflow velocity in the elevator parallel control box.

[0015] Furthermore, the dust removal mechanism includes a dust removal frame fixed on the air inlet chamber, a dust removal plate is provided on the dust removal frame, two symmetrical sliding rails are fixed inside the dust removal frame, the dust removal plate is slidably connected to the two sliding rails, a push-pull plate is fixed to one end of the dust removal plate, and a fixing component is provided between the push-pull plate and the dust removal frame.

[0016] By adopting the above technical solution, when the air intake fan draws outside air into the air intake chamber, the dust removal plate on the dust removal frame filters the dust particles carried in the air, thereby reducing the possibility of dust particles entering the elevator parallel control box and causing dust particles to accumulate on electrical components, affecting the heat dissipation of electrical components.

[0017] Furthermore, the fixing component includes a fixing block fixed on the dust removal frame, a plug-in block fixed on the push-pull plate, a plug-in groove on the fixing block, a limit block slidably connected on the fixing block, and limit teeth facing opposite directions on both the limit block and the plug-in block.

[0018] By adopting the above technical solution, the plug-in block on the push-pull plate is inserted into the fixing block on the dust removal frame, and then the limiting block is used to limit the plug-in block, so that the dust removal plate can be easily fixed in the dust removal frame.

[0019] Furthermore, two symmetrical abutment springs are provided between the limiting block and the fixing block, and both ends of the abutment springs are fixedly connected to the fixing block and the limiting block.

[0020] By adopting the above technical solution, the limiting block is supported by the anti-collision spring, so that the plug-in block can be inserted into the fixed block, and the limiting teeth on the limiting block can mesh with the limiting teeth on the plug-in block.

[0021] Furthermore, a pull rod is fixed on the limiting block, one end of which passes through the fixed block and is slidably connected to it.

[0022] By adopting the above technical solution, pulling the pull rod causes the pull rod to move the limiting block, which in turn squeezes the contact spring. At the same time, the limiting block separates from the plug-in block, thus making it easy to pull the plug-in block out of the fixing block.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application, by allowing passengers to select to go up or down the elevator using the call panel A or B outside elevator A or elevator B, sends a signal to the elevator parallel control box. The camera A or camera B in elevator A or elevator B then transmits a signal to the elevator parallel control box. The signal includes the elevator's direction of travel and the number of floor options on the elevator's selection panel. After comprehensive judgment, the elevator parallel control box sends a signal to control box A or control box B, causing the nearest, not fully loaded elevator to stop at the corresponding floor. The corresponding control box A or control box B then opens the corresponding elevator door. This achieves the goal of connecting elevators of different brands in parallel, arranging suitable elevators to stop at corresponding floors, and improving the overall operating efficiency and service level of the elevator system.

[0025] 2. In this application, during the operation of the elevator parallel control box, an intake fan draws outside air into the intake chamber, while a dust removal plate filters dust particles carried in the air. Then, guided by the air guide plate in the intake chamber, the air is blown towards the elevator parallel control box. The air then passes through the partition plate into the elevator parallel control box. Simultaneously, an exhaust fan draws air from the elevator parallel control box into the exhaust chamber, and then exhausts it from the exhaust chamber to the outside of the elevator parallel control box, completing the air exchange within the elevator parallel control box. At the same time, a protective net protects the exhaust fan, achieving the purpose of reducing the operating temperature inside the elevator parallel control box, reducing dust particles adhering to electrical components, and reducing the possibility of excessive temperature affecting the normal operation of electrical components.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a device for controlling the parallel operation of different elevator models.

[0034] Reference Figure 1 , Figure 2 and Figure 3A device for controlling the parallel operation of different elevator models includes an elevator parallel control box 1, a box door 2 installed on the elevator parallel control box 1, a heat dissipation mechanism 3 installed on the elevator parallel control box 1, a dust removal mechanism 4 installed on the elevator parallel control box 1, an A control box 5 electrically connected to the elevator parallel control box 1, a B control box 6 electrically connected to the elevator parallel control box 1, an A call board 7 electrically connected to the elevator parallel control box 1, a B call board 8 electrically connected to the elevator parallel control box 1, an A camera electrically connected to the elevator parallel control box 1, and a B camera electrically connected to the elevator parallel control box 1.

[0035] When two elevator models are used together, after a passenger selects to go up or down using call panel 7 (A) or call panel 8 (B) outside elevator A or B, call panel 7 or call panel 8 sends a signal to the elevator parallel control box 1. Camera A or camera B in elevator A or B then transmits a signal to the elevator parallel control box 1. This signal includes the elevator's direction of travel and the number of floor options on the elevator's control panel. After comprehensive judgment, elevator parallel control box 1 sends a signal to control box 5 (A) or control box 6 (B), causing the nearest, less-loaded elevator to stop at the corresponding floor. The corresponding control box 5 (A) or control box 6 (B) then opens the corresponding elevator door, completing the efficient stopping of the elevator. While operating normally, the cooling mechanism 3 cools the elevator parallel control box 1, and the dust removal mechanism 4 removes dust from the air about to enter the elevator parallel control box 1. By connecting two different brands of elevators in parallel to the elevator parallel control box 1, and then using the cooperation of camera A, camera B, control box A 5, control box B 6, call board A 7, and call board B 8, the corresponding elevators can be stopped at the required floors. This allows for the parallel connection of elevators of different brands, arranging appropriate elevators to stop at the corresponding floors, improving the overall operating efficiency and service level of the elevator system, and reducing the operating temperature inside the elevator parallel control box 1, thus reducing the possibility of excessive temperature affecting the normal operation of electrical components.

[0036] Reference Figure 2 and Figure 3 The heat dissipation mechanism 3 includes an air inlet chamber 31 fixed to the bottom of the elevator parallel control box 1, and an air outlet chamber 32 fixed to the top of the elevator parallel control box 1. The air inlet chamber 31 and the air outlet chamber 32 are both connected to the elevator parallel control box 1. An air inlet fan 33 is fixed inside the air inlet chamber 31, and an air outlet fan 34 is fixed in the air outlet chamber 32. A protective net 37 is fixed on the air outlet chamber 32, and the protective net 37 corresponds to the air outlet fan 34.

[0037] In addition, partition plates 35 are fixed between the air outlet chamber 32, the air inlet chamber 31 and the elevator parallel control box 1.

[0038] Furthermore, several air guide plates 36 are fixed inside the air intake chamber 31, and the air guide plates 36 are arranged in a stepped manner.

[0039] During operation, the elevator parallel control box 1 uses an intake fan 33 to draw in outside air into the intake chamber 31. Guided by the air guide plate 36 in the intake chamber 31, the air is directed towards the elevator parallel control box 1. The air then passes through the partition plate 35 and enters the elevator parallel control box 1. Simultaneously, the exhaust fan 34 draws air from the elevator parallel control box 1 into the exhaust chamber 32, and then discharges it outside the elevator parallel control box 1, completing the air exchange within the elevator parallel control box 1. At the same time, the protective net 37 protects the exhaust fan 34, reducing the possibility of foreign objects contacting the exhaust fan 34 and affecting its operation. By using the intake fan 33 to send outside air into the elevator parallel control box 1 and the exhaust fan 34 to draw out the air from the elevator parallel control box 1, the operating temperature inside the elevator parallel control box 1 can be reduced, minimizing the possibility of excessive temperature affecting the normal operation of electrical components.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The dust removal mechanism 4 includes a dust removal frame 41 fixed on the air inlet chamber 31, a dust removal plate 42 is provided on the dust removal frame 41, two symmetrical sliding rails 43 are fixed inside the dust removal frame 41, the dust removal plate 42 is slidably connected to the two sliding rails 43, a push-pull plate 44 is fixed to one end of the dust removal plate 42, and a fixing component 45 is provided between the push-pull plate 44 and the dust removal frame 41.

[0041] In addition, the fixing component 45 includes a fixing block 451 fixed on the dust removal frame 41, a plug-in block 452 fixed on the push-pull plate 44, a plug-in groove on the fixing block 451, a limit block 453 slidably connected on the fixing block 451, and limit teeth facing opposite directions on both the limit block 453 and the plug-in block 452.

[0042] Furthermore, two symmetrical abutment springs 454 are provided between the limiting block 453 and the fixing block 451, and both ends of the abutment springs 454 are fixedly connected to the fixing block 451 and the limiting block 453.

[0043] Furthermore, a pull rod 455 is fixed on the limiting block 453, one end of which passes through the fixing block 451 and is slidably connected to the fixing block 451.

[0044] When the air intake fan 33 draws outside air into the elevator parallel control box 1, the outside air passes through the dust removal plate 42, which filters out dust particles from the air, reducing the possibility of dust particles entering the elevator parallel control box 1. When it is necessary to clean the dust removal plate 42, pull the pull rod 455, causing the pull rod 455 to drive the limit block 453, causing the limit teeth on the limit block 453 to separate from the limit teeth on the plug-in block 452. Then, pull the push-pull plate 44 directly, causing the push-pull plate 44 to drive the dust removal plate 42, allowing the dust removal plate 42 to move under the support of the sliding rail 43, removing the dust removal plate 42 from the dust removal frame 41. Then, clean the dust removal plate 42. After cleaning, reinsert the dust removal plate 42 onto the sliding rail 43 on the dust removal frame 41, causing the push-pull plate 44 to drive the plug-in block 452. Insert the plate into the slot of the fixing block 451, and then the inclined surface of the limiting tooth on the plug block 452 abuts against the inclined surface of the limiting tooth on the limiting block 453, allowing the limiting block 453 to slide in the fixing block 451. When the push-pull plate 44 is completely against the dust removal frame 41, under the push of the abutment spring 454, the limiting teeth on the limiting block 453 and the limiting teeth on the plug block 452 are engaged, thus completing the fixation of the dust removal plate 42. By placing the dust removal plate 42 in front of the air inlet chamber 31, the outside air is filtered when passing through the dust removal plate 42. At the same time, the dust removal plate 42 can slide on the dust removal frame 41, thereby reducing the possibility of outside air carrying dust particles into the elevator parallel control box 1 and affecting the normal heat dissipation of the electrical components in the elevator parallel control box 1. It also facilitates the disassembly and cleaning of the dust removal plate 42.

[0045] Working Principle: When two elevator models are used together, after a passenger selects to go up or down using call panel 7 (A) or call panel 8 (B) outside elevator A or B, call panel 7 or call panel 8 sends a signal to the elevator parallel control box 1. Camera A or camera B in elevator A or B then transmits a signal to the elevator parallel control box 1, including the elevator's direction of travel and the number of floor options on the elevator's control panel. After comprehensive judgment, the elevator parallel control box 1 sends a signal to control box 5 (A) or control box 6 (B), causing the nearest, less-loaded elevator to stop at the corresponding floor. The corresponding control box 5 (A) or control box 6 (B) then opens the corresponding elevator door, completing the high-efficiency elevator operation. When the elevator is stopped, during use, the air intake fan 33 draws outside air into the air intake chamber 31, while the dust removal plate 42 filters the dust particles in the air. Then, guided by the air guide plate 36 in the air intake chamber 31, the air is blown towards the elevator parallel control box 1. The air then passes through the partition plate 35 and enters the elevator parallel control box 1. At the same time, the air outlet fan 34 draws the air in the elevator parallel control box 1 into the air outlet chamber, and then discharges it from the air outlet chamber 32 to the outside of the elevator parallel control box 1, completing the air exchange in the elevator parallel control box 1. Meanwhile, the protective net 37 protects the air outlet fan 34 to reduce the contact between foreign objects and the air outlet fan 34.
