Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a villa elevator structure. Background Technology

[0002] Currently, most villa elevators are platform elevators without a car, designed to save space. Existing technology, such as the car position detection device for platform elevators disclosed in Chinese patent application CN202320015851.8, uses a grating ruler reader mounted on a backpack frame to detect the car's height position. While this design meets the basic requirements of elevator operation to some extent, it has a significant drawback: it relies solely on a single grating ruler reader for detection.

[0003] In practical applications, a single optical encoder reading head is susceptible to various external factors, such as electromagnetic interference, dust accumulation, and mechanical vibration. These factors can all cause deviations in the data read by the reading head, thus affecting the accuracy of car position detection. Inaccurate detection data can lead to abnormal elevator operation and even endanger passenger safety.

[0004] Furthermore, the single-reader design lacks redundancy and fault warning mechanisms. If the reader fails, the system will be unable to obtain accurate car position information in a timely manner, which may lead to elevator shutdown or other emergency measures, causing inconvenience to passengers and potentially increasing maintenance costs. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a villa elevator structure.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] A villa elevator structure includes a platform car frame, a hoist frame, and a counterweight device. The hoist frame houses car frame guide rails and counterweight guide rails. The platform car frame is guided and fitted onto the car frame guide rails, and the counterweight device is guided and fitted onto the counterweight guide rails. A main unit mounting frame is installed on the top of both the car frame guide rails and the counterweight guide rails. A traction main unit is mounted on the main unit mounting frame. The traction sheave of the traction main unit drives the platform car frame and counterweight device to move via a steel wire rope or steel belt. The traction main unit is controlled by an elevator controller.

[0008] The platform car frame includes a backpack frame, a car bottom module connected to the lower front side of the backpack frame, and a car frame guide device installed on the rear side of the backpack frame. The car frame guide device is guided and fitted on the car frame guide rail. The car frame guide device is characterized in that: grating ruler reading heads are provided on both the left and right sides of the car frame guide device. The grating ruler reading heads are connected to the elevator controller. Each grating ruler reading head corresponds to the detection of a vertical grating ruler. The top and bottom of the vertical grating ruler are provided with grating mounting brackets installed on the car frame guide rail.

[0009] In this invention, a car wall module is installed on the front of the backpack frame, the back of the car wall module is snapped onto the backpack frame, and the lower end of the car wall module presses against the top of the car bottom module.

[0010] In this invention, the backpack frame is provided with at least two car wall connecting seats, the car wall connecting seats are fixedly connected to the backpack frame, the back of the car wall connecting seat is provided with a car wall connecting groove, the front of the car wall connecting seat is provided with a car wall buckle hole that passes through and communicates with the car wall connecting groove, and the back of the car wall module is provided with a car wall fastener that extends from the car wall buckle hole and is snapped into the car wall connecting groove.

[0011] In this invention, the car frame guiding device includes two guiding systems and two guide columns arranged opposite each other. The two guiding systems are respectively installed on the inner side of the two guide columns. Each guiding system includes a first car frame guiding module and a second car frame guiding module. The first car frame guiding module and the second car frame guiding module are arranged from top to bottom. The first car frame guiding module and the second car frame guiding module are guided and connected to the car frame guiding protrusion of the car frame guide rail. The guide column is provided with a guide mounting seat that is connected to the backpack frame.

[0012] In this invention, the car frame guiding device further includes a rope end connecting seat and a car frame buffer mating seat located between two guide columns, and the left and right ends of the rope end connecting seat and the car frame buffer mating seat are respectively fixedly connected to the two guide columns.

[0013] In this invention, the second car frame guide module includes a car frame guide plate, an intermediate guide wheel corresponding to the guide end face of the car frame guide protrusion, a side swing guide wheel module corresponding to one guide side of the car frame guide protrusion, and a side adjustable guide wheel module corresponding to the other guide side of the car frame guide protrusion.

[0014] In this invention, the car frame guide plate is mounted on the guide column, the intermediate guide wheel is mounted on the car frame guide plate, and the side swing guide wheel module includes a swing frame rotatably mounted in the middle on the car frame guide plate, and two swing guide wheels rotatably mounted on the upper and lower ends of the swing frame respectively; the side adjustable guide wheel module includes two adjustable guide wheels distributed from top to bottom, and the adjustable guide wheels are mounted on the car frame guide plate in a way that allows for front-to-back adjustment of the mounting shaft position.

[0015] In this invention, a grating ruler reading head is installed on the outside of each guide column, and the grating ruler reading head is installed on the outside of the guide column using a reading head bracket.

[0016] In this invention, the guide column is equipped with an electronic safety clamp, which is connected and controlled by the elevator controller, and the electronic safety clamp is correspondingly engaged with the car frame guide rail.

[0017] In this invention, the derrick is provided with a decorative partition plate, which divides the internal space of the derrick into a front lifting space and a rear lifting space distributed front and rear. The car frame guide device, counterweight device, two car frame guide rails and two counterweight guide rails are all located in the rear lifting space. The backpack frame is located in the front lifting space. One end of the guide mounting seat is connected to the backpack frame in the front lifting space, and the other end is connected to the guide column in the rear lifting space.

[0018] The beneficial effects of this invention are as follows: By setting two independent grating ruler reading heads, this invention achieves dual detection of the platform car frame position. When the readings of the two reading heads are basically consistent, the average value is taken as the final platform car frame position data. This effectively reduces the error that may be caused by external factors due to a single reading head, improves detection accuracy, ensures the smooth operation and accurate stopping of the elevator, and thus enhances the passenger riding experience and satisfaction. Moreover, the dual reading head design provides a redundant detection mechanism. Even if one reading head fails to work properly due to a malfunction or error, the other reading head can still provide effective platform car frame position information, ensuring the continuous safe operation of the elevator system. This greatly reduces the risk of elevator shutdown due to a single reading head failure and improves the overall reliability of the system. In addition, the control system can monitor the difference in readings between the two reading heads in real time. When the difference exceeds a preset threshold, the system will trigger a fault warning mechanism to prompt maintenance personnel to inspect and repair. This helps to promptly detect and deal with potential safety hazards and avoid accidents. Attached Figure Description

[0033] Reference Figure 1-10A villa elevator structure includes a platform car frame 100, a hoist frame 200, and a counterweight device 300. Two car frame guide rails 400 and two counterweight guide rails 500 are installed inside the hoist frame 200. The platform car frame 100 is guided and fitted onto the two car frame guide rails 400, and the counterweight device 300 is guided and fitted onto the two counterweight guide rails 500. The counterweight device 300 is located behind the platform car frame 100. A main unit mounting frame 600 is mounted on the top of both the car frame guide rails 400 and the counterweight guide rails 500. A traction main unit 700 is mounted on the main unit mounting frame 600. The traction sheave of the traction main unit 700 is connected to and controls the platform car frame 100 and the counterweight device 300 via a wire rope or steel belt. The traction main unit 700 is connected to and controlled by an elevator controller 800, which controls the operation of the traction main unit 700.

[0034] Furthermore, the platform car frame 100 includes a backpack frame 110, a car bottom module 120 connected to the front side of the lower end of the backpack frame 110, and a car frame guide device installed on the rear side of the backpack frame 110. The car frame guide device is used for guiding connection with the car frame guide rail 400.

[0035] Furthermore, the car frame guide device is equipped with two grating ruler reading heads 10, which are connected to the elevator controller 800. Each grating ruler reading head 10 detects a vertical grating ruler 20. The vertical grating ruler 20 passes through the monitoring hole of the grating ruler reading head 10. The top and bottom of the vertical grating ruler 20 are equipped with grating mounting brackets installed on the car frame guide rail 400.

[0036] In this embodiment, a car wall module 190 is installed on the front of the backpack frame 110, and the back of the car wall module 190 is snapped onto the backpack frame 110. The lower end of the car wall module 190 presses against the top of the car bottom module 120. Furthermore, the backpack frame 110 is provided with at least two car wall connecting seats 112, preferably four car wall connecting seats 112 distributed in a quadrilateral shape, and the car wall connecting seats 112 are fixedly connected to the backpack frame 110; the back of the car wall connecting seat 112 is provided with a car wall connecting groove, and the front of the car wall connecting seat 112 is provided with a car wall fastening hole that penetrates and communicates with the car wall connecting groove. The back of the car wall module 190 is provided with a car wall fastening component 191 that extends into the car wall fastening hole and is fastened in the car wall connecting groove. Each car wall connecting seat 112 corresponds to at least one car wall fastening component 191. The car wall fastening component 191 includes a car wall fastening rod and a car wall fastening head connected in sequence. The car wall fastening rod is used to cooperate with the car wall module 190 to achieve the installation of the car wall fastening component 191. The car wall fastening head of the car wall fastening component 191 enters the car wall connecting groove from the car wall fastening hole and is fastened in the car wall connecting groove.

[0037] In this embodiment, the specific car wall fastening hole includes a car wall through hole 1121 and a car wall limiting hole 1122 connected sequentially from top to bottom. The car wall fastening rod and the car wall fastening head extend into the car wall connecting groove from the car wall through hole 1121. The car wall fastening head is configured to apply pressure to the wall of the car wall connecting groove to restrict the car wall fastening component 191 from moving forward and disengaging from the car wall connecting groove, thereby achieving the purpose of fastening the car wall module 190 onto the backpack frame 110. Preferably, the car wall fastening component 191 is a car wall fastening bolt, wherein the car wall fastening head is the bolt head of the fastening connector; the car wall fastening rod is the threaded part of the car wall fastening bolt, and the end of the car wall fastening rod away from the car wall fastening head is threaded into the car wall fastening threaded hole on the car wall module 190.

[0038] During the installation of the car wall module 190, the car wall fastener 191 is first installed on the car wall module 190. Then, the car wall module 190 is lifted so that both the car wall fastening rod and the car wall fastening head are inserted into the car wall connecting groove. Next, the car wall module 190 is lowered. During this process, the car wall fastening rod moves downwards into the car wall limiting hole 1122, and the car wall fastening head is below the car wall through hole 1121, until the bottom of the car wall module 190 presses against the top of the car bottom module 120. Then, along the first... When the car wall fastening head is rotated in the second direction, it can press the back of the car wall connecting groove more firmly, thereby locking the car wall module 190 and realizing the fixed installation of the car wall module 190. When the car wall module 190 is disassembled, rotating the car wall fastening head in the second direction can release the car wall fastening head from pressing the back of the car wall connecting groove, so that the installer can lift the car wall module 190 and then the car wall fastening head can be disassembled from the car wall through hole 1121 position for disassembly and assembly of the car wall module 190. In addition, to improve the quality of fixing the car wall module 190 to the car wall fastener 191, a car wall fastener washer is fitted on the car wall fastener rod. The car wall fastener washer can enter the car wall connecting groove through the car wall through hole 1121. The car wall fastener washer is used to press against the wall of the car wall connecting groove. At the same time, multiple car wall fastener anti-slip protrusions are provided on the side of the car wall fastener facing the front of the car wall connecting groove. As the car wall fastener 191 tightens, the car wall fastener anti-slip protrusions press against the wall of the car wall connecting groove, so that the car wall module 190 is more firmly locked on the backpack frame 110, so as to prevent the car wall module 190 from sliding after the car wall fastener 191 tightens.

[0039] In this embodiment, the car frame guiding device includes two guiding systems, two guide columns 113 arranged opposite each other, and a rope end connecting seat 114 and a car frame buffer mating seat 115 located between the two guide columns 113. The two guiding systems are respectively installed on the inner sides of the two guide columns 113. Each guiding system includes a first car frame guiding module 116 and a second car frame guiding module 117, which are arranged from top to bottom. The first car frame guiding module 116 and the second car frame guiding module 117 are guided and connected to the car frame guiding protrusion of the car frame guide rail 400. The guide column 113 is provided with a guide mounting seat 118 connected to the backpack frame 110, so that the backpack frame 110 and the car frame guiding device are combined and connected together. The left and right ends of the rope end connecting seat 114 and the car frame buffer mating seat 115 are respectively fixedly connected to the two guide columns 113, so that the two guide columns 113 are combined and fixed together, ensuring the structural stability of the entire device.

[0040] In this embodiment, the first car frame guide module 116 adopts a car frame guide shoe installed on the guide column 113; the second car frame guide module 117 includes a car frame guide plate 1171, an intermediate guide wheel 1172 corresponding to the guide end face of the car frame guide protrusion, a side swing guide wheel module corresponding to one guide side of the car frame guide protrusion, and a side adjustable guide wheel module corresponding to the other guide side of the car frame guide protrusion. The car frame guide plate 1171 is installed on the guide column 113, and the intermediate guide wheel 1172, the side swing guide wheel module, and the side adjustable guide wheel module are all installed on the car frame guide plate 1171. The intermediate guide wheel 1172, the side swing guide wheel module, and the side adjustable guide wheel module are triangularly distributed when viewed from above. Specifically, the intermediate guide wheel 1172 is mounted on the car frame guide plate 1171 via an intermediate guide wheel shaft. The side swing guide wheel module includes a swing frame 1174 rotatably mounted on the car frame guide plate 1171 via a guide wheel mounting shaft 1173 in the middle, and two swing guide wheels 1175 rotatably mounted on the upper and lower ends of the swing frame 1174, respectively. The side adjustable guide wheel module includes two adjustable guide wheels 1176 distributed from top to bottom. The adjustable guide wheels 1176 are mounted on the car frame guide plate 1171 with adjustable positions that can be adjusted forward and backward via an adjustable mounting shaft 1177. Specifically, the car frame guide plate 1171 has a length... The adjustable mounting shaft 1177 has a guide wheel adjustment hole extending from front to back. The screw part of the adjustable mounting shaft 1177 passes through the guide adjustment hole and is threaded with a guide wheel locking nut 1178. After the guide wheel locking nut 1178 is loosened, the adjustable mounting shaft 1177 can move back and forth along the guide wheel adjustment hole, so that the adjustable guide wheel 1176 can roll better in contact with the car frame guide protrusion. At the same time, the swing frame 1174 can swing around the center of the guide wheel mounting shaft 1173, so that the swing guide wheel 1175 can roll better in contact with the car frame guide protrusion. This allows the second car frame guide module 117 to better cooperate with the car frame guide rail 400 for guidance, thereby improving the running stability of the platform car frame.

[0041] In this embodiment, a grating ruler reader 10 is installed on the outer side of each guide column 113. The grating ruler reader 10 is mounted on the outer side of the guide column 113 using a reader bracket. When the platform car 100 moves up and down, the grating ruler reader 10 feeds back the monitoring data to the elevator controller 800 in real time, allowing the elevator controller 800 to confirm the height position of the platform car 100 in real time. Furthermore, by using two grating ruler readers 10 to detect simultaneously, the elevator controller 800 can obtain the height position of the platform car 100 more accurately, enabling the elevator controller 800 to more precisely control the platform car 100 to go to different floors.

[0042] In this embodiment, an electronic safety clamp 30 is provided on the guide column 113. The electronic safety clamp 30 is connected and controlled by the elevator controller 800, and the electronic safety clamp 30 is correspondingly engaged with the car frame guide rail 400. During operation, the elevator controller 800 uses the grating ruler reading head 10 and the vertical grating ruler 20 to monitor the moving speed of the platform car frame 100. When the moving speed of the platform car frame 100 exceeds a preset threshold, the elevator controller 800 controls the electronic safety clamp 30 to engage and lock onto the car frame guide rail 400, thereby stopping the electronic safety clamp 30.

[0043] In a preferred embodiment, the car bottom module 120 is equipped with an anti-pinch safety frame 150 suspended around its outer periphery via an elastic support module 130. The anti-pinch safety frame 150 includes a safety crossbar 151 corresponding to the front side of the car bottom module 120 and two safety sidebars 152 corresponding to the left and right sides of the car bottom module 120, respectively. The front ends of the two safety sidebars 152 are fixed to the left and right ends of the safety crossbar 151. The car bottom module 120 includes a car bottom cover, the interior of which is a hidden space. The elevator has safety engagement ports on its left and right sides that connect to a hidden space. An anti-pinch monitoring switch 160 corresponding to the safety engagement port is located within the hidden space. The anti-pinch monitoring switch 160 is connected to the elevator controller 800. In this embodiment, the anti-pinch monitoring switch 160 is a micro switch. The inner side of the safety side rod 152 has a switch engagement seat 153 extending from the safety engagement port into the safety engagement space. The switch engagement seat 153 has an anti-pinch trigger part 1531 corresponding to the trigger end of the anti-pinch monitoring switch 160 within the engagement space.

[0044] This embodiment first achieves concealed installation of the anti-pinch monitoring switch 160 by installing it in a hidden space, thus improving the aesthetics of the villa elevator and reducing the risk of damage to the anti-pinch monitoring switch 160. Then, a switch mating seat 153 is provided inside the safety side rod 152 of the anti-pinch safety frame 150, extending from the safety mating port into the safety mating space. The switch mating seat 153 has an anti-pinch trigger part 1531 corresponding to the trigger end of the anti-pinch monitoring switch 160 within the mating space. When a passenger steps on or an object presses against the anti-pinch safety frame 150, the anti-pinch function is activated. When the safety frame 150 descends, the anti-pinch trigger 1531 activates the trigger end of the anti-pinch monitoring switch 160, causing the elevator to stop running and thus preventing damage to people or the elevator, effectively ensuring the safety of passengers. When the external force on the anti-pinch safety frame 150 is eliminated, the anti-pinch safety frame 150 moves upward and resets under the elastic restoring force of the elastic support module 130. At this time, the anti-pinch trigger 1531 leaves the trigger end of the anti-pinch monitoring switch 160, thereby returning the elevator to normal operation. This achieves anti-pinch monitoring for the villa elevator, ensuring the safety of the villa elevator.
