[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example 1: Reference Figure 1-Figure 7 A chain-type household elevator suitable for a small space comprises: a derrick 1, a drive system 2, a control system 3 and a car frame 4. The drive system 2 is installed at the bottom of the derrick 1, the output end of the drive system 2 is connected to the car frame 4, the car frame 4 is arranged above the drive system 2, the car frame 4 is slidably connected to the derrick 1, and a control system 3 is arranged in the derrick 1 to control the drive system 2 and the car frame 4.

[0028] The principle of the above scheme is:

[0029] A driving system 2 is installed at the bottom of the derrick 1 , and an output end of the driving system 2 is connected to the car frame 4 . The control system 3 controls the upward or downward lifting and sliding of the car frame 4 in the derrick 1 through the driving system 2 .

[0030] The beneficial effects of the above scheme are:

[0031] The drive system 2 is arranged at the bottom of the derrick 1, and no additional mounting frame is required, which increases the compactness between components, reduces the space occupied in the derrick 1, and improves the applicability of the installed elevator to low-rise residential buildings.

[0032] Example 2: Reference Figure 1-Figure 7 The derrick 1 includes: a shaft top plate 11, a shaft bottom plate 12, a shaft frame 13, an automatic door 14 and a laminated glass 15. The shaft top plate 11 is installed on the top of the shaft frame 13, the shaft bottom plate 12 is installed on the bottom of the shaft frame 13, and the side of the shaft frame 13 is equipped with laminated glass 15 and multiple automatic doors 14. The shaft top plate 11, the shaft bottom plate 12, the automatic door 14 and the laminated glass 15 seal the inside of the shaft frame 13.

[0033] The principle of the above scheme is:

[0034] The derrick 1 is composed of a shaft top plate 11, a shaft bottom plate 12, a shaft frame 13, an automatic door 14 and a laminated glass 15. The shaft top plate 11 seals the top end of the shaft frame 13, and the shaft bottom plate 12 seals the bottom end of the shaft frame 13. Different numbers of automatic doors 14 are arranged on the shaft frame 13 according to the number of floors. The automatic doors 14 cooperate with the laminated glass 15 to seal the side of the shaft frame 13.

[0035] The beneficial effects of the above scheme are:

[0036] The shaft frame 13 is made of aluminum alloy materials, which ensures the strength of the shaft frame 13 while reducing its overall weight. By setting up the shaft frame 13, there is no need to dig a pit to facilitate the installation of the elevator, and the shaft frame 13 can be adapted to the installation of elevators in lower top-floor buildings.

[0037] Example 3: Reference Figure 1-Figure 7 The control system 3 and the T-shaped guide rail 16 are installed in the shaft frame 13, the T-shaped guide rail 16 is slidably connected to the car frame 4, the automatic door 14 is arranged toward the car frame 4, the driving system 2 is installed on the shaft bottom plate 12, and the elevator call box 17 is installed outside the shaft frame 13.

[0038] The car frame 4 includes: a back plate 41 and guide shoes 43. A group of guide shoes 43 are respectively installed on both sides of the end surface of the back plate 41. The two guide shoes 43 in the same group are longitudinally arranged and slidably connected to a T-shaped guide rail 16. The T-shaped guide rail 16 is longitudinally installed in the hoistway frame 13.

[0039] The car frame 4 further includes: a floor 42 and a touch screen 45 . The other end surface of the back plate 41 is provided with the floor 42 and the touch screen 45 . The touch screen 45 is arranged above the floor 42 , and the top surface of the floor 42 is arranged toward the automatic door 14 .

[0040] The principle of the above scheme is:

[0041] A control system 3, a T-shaped guide rail 16 and a drive system 2 are installed in the hoistway frame 13, and a call box 17 is installed outside the hoistway frame 13. The T-shaped guide rail 16 is slidably connected to a guide shoe 43 on a car frame 4, and the guide shoe 43 is connected to a back plate 41. A user can enter the car frame 4 through an automatic door 14, and a floor 42 provides a space for the user to sit.

[0042] The beneficial effects of the above scheme are:

[0043] The shaft frame 13 provides an installation position for the control system 3, the T-shaped guide rail 16 and the elevator call box 17; the T-shaped guide rail 16 and the guide shoe 43 cooperate to provide guidance for the car frame 4 to slide up and down in the shaft frame 13, and at the same time, the guide shoes 43 are symmetrically arranged on both sides of the back plate 41. Two guide shoes 43 form a group and are not easy to generate horizontal force during the sliding process with a T-shaped guide rail 16, so the potential torque is eliminated, and the stability and safety of the car frame 4 during operation are improved.

[0044] Example 4: Reference Figure 1-Figure 7 The driving system 2 includes: a chain guide 211, a U-shaped joint 212, a driving box 213, a device fixing plate 214, a push chain 215 and a sprocket 216. The driving box 213 is installed on the shaft bottom plate 12. A chain guide 211 is installed on each of the two inner walls of the driving box 213. The chain guide 211 is specifically U-shaped. The side of the push chain 215 is rollingly connected in the chain guide 211. A bearing is provided at the center of the bottom of the chain guide 211. The end of the rotating shaft is mounted in the bearing. A sprocket 216 is coaxially installed on the rotating shaft. The sprocket 216 is meshed and connected with the push chain 215.

[0045] The end of the rotating shaft extending out of the driving box 213 is connected to the end of the planetary gear reducer 22 , the planetary gear reducer 22 is installed on the driving box 213 , the other end of the planetary gear reducer 22 is connected to the output end of the servo motor 23 , and the servo motor 23 is connected to the planetary gear reducer 22 .

[0046] The principle of the above scheme is:

[0047] The push chain 215 is specifically a reciprocating push chain. When the height of the end of the push chain 215 needs to be adjusted upward, the servo motor 23 is started, and the output end of the servo motor 23 rotates forward to drive the planetary gear reducer 22 to rotate forward, and the planetary gear reducer 22 drives the sprocket 216 to rotate forward, and the push chain 215 moves along the chain guide rail 211, and the chain guide rail 211 is specifically U-shaped, and the end of the push chain 215 moves upward; when the height of the end of the push chain 215 needs to be adjusted downward, the servo motor 23 is started, and the output end of the servo motor 23 is reversed to drive the planetary gear reducer 22 to reverse, and the planetary gear reducer 22 drives the sprocket 216 to reverse, and the push chain 215 moves along the chain guide rail 211, and the end of the push chain 215 moves downward.

[0048] The beneficial effects of the above scheme are:

[0049] Since the chain guide rail 211 is U-shaped, the chain guide rail 211 is slidably connected to the side of the push chain 215, and the push chain 215 is an open-loop structure, the push chain 215 is always in a compressed state during the process of the sprocket 216 driving the push chain 215 to move, and the links in the push chain 215 are only subjected to the squeezing force and are not affected by the pulling force, which effectively avoids the risk of stretching and breaking of the push chain 215 and has higher safety. In the elevator driven by the push chain 215, the U-shaped guide rail is used to store the push chain 215, which greatly reduces The device size is reduced, and the occupation of the internal space of the shaft frame 13 is greatly reduced; the drive system 2 has only two connection positions in the elevator, namely, it is directly connected to the shaft frame 13 and the car frame 4, and there is no need to add an additional support frame, which greatly reduces the complexity of the internal structure of the shaft frame 13, making the overall space neat and beautiful; the push chain 215 is a modular component and does not need to be assembled on site. It only needs to be installed in the drive box 213 before being placed in the shaft frame 13, which makes the entire elevator structure simple and quick to install, and at the same time can increase the efficiency of the inspection and maintenance of the push chain 215.

[0050] Example 5: Reference Figure 1-Figure 7 The driving box 213 has a longitudinal through slot on its side, which is arranged toward the back plate 41. A U-shaped joint 212 is slidably connected in the through slot. The end of the U-shaped joint 212 is connected to the end of the push chain 215. The other end of the U-shaped joint 212 is connected to the bottom end of the connecting plate 44. A weighing module 33 is installed on the top end of the connecting plate 44. The top end of the weighing module 33 is connected to the bottom end of the rubber component 34, and the top end of the rubber component 34 is connected to the back plate 41.

[0051] The principle of the above scheme is:

[0052] When the end of the push chain 215 moves upward, the end of the push chain 215 drives the U-shaped joint 212 to move upward synchronously, the end of the U-shaped joint 212 is slidably connected to the through slot, and the connecting plate 44, the weighing module 33 and the rubber component 34 at the other end of the U-shaped joint 212 move upward synchronously; when the end of the push chain 215 moves downward, the end of the push chain 215 drives the U-shaped joint 212 to move downward synchronously, the U-shaped joint 212 is slidably connected to the through slot, and the connecting plate 44, the weighing module 33 and the rubber component 34 at the other end of the U-shaped joint 212 move downward synchronously

[0053] The beneficial effects of the above scheme are:

[0054] Since the push chain 215 has the characteristics of high strength, wear resistance and impact resistance, the push chain 215 is used instead of the common wire rope traction assembly to drive the elevator, which can reduce the maintenance of the elevator and increase the service life; at the same time, the setting of the balance centering system is reduced, and the applicability of the device to high-rise buildings is improved.

[0055] Example 6: Reference Figure 1-Figure 7 The side wall of the floor 42 is provided with an end of an anti-pinch module 32 , and the other end of the anti-pinch module 32 is clearance-matched with the hoistway frame 13 , and the anti-pinch module 32 is specifically a micro switch.

[0056] The principle of the above scheme is:

[0057] The anti-pinch module 32 is disposed on the floor 42 and is specifically a micro switch. When the car frame 4 is raised or lowered, the micro switch is squeezed and triggered after encountering an obstacle.

[0058] The beneficial effects of the above scheme are:

[0059] The anti-pinch module 32 can be provided to prevent the elevator from being stuck by obstacles during operation.

[0060] Example 7: Reference Figure 1-Figure 7 The control system 3 includes: an elevator call box 17, a grating ruler module 31, and an electrical control cabinet 35. The shaft frame 13 is equipped with an electrical control cabinet 35. One side of the electrical control cabinet 35 is electrically connected to the power supply through a cable, and the other side of the electrical control cabinet 35 is electrically connected to the servo motor 23, the grating ruler module 31, the elevator call box 17, the touch screen 45, the weighing module 33 and the automatic door 14 through wire 1, wire 2, wire 3, wire 4, wire 5 and wire 6 respectively. The transmitting end of the grating ruler module 31 is installed in the shaft frame 13, and the transmitting end of the grating ruler module 31 is arranged toward the back plate 41 and the connecting plate 44. The receiving end of the grating ruler module 31 is installed on the connecting plate 44. The receiving end of the grating ruler module 31 is electrically connected to the electrical control cabinet 35 through wire 7, and the micro switch is electrically connected to the control cabinet 35 through wire 8.

[0061] The principle of the above scheme is:

[0062] The passenger calls the elevator through the elevator call box 17, and the elevator call box 17 transmits the signal to the electrical control cabinet 35 through the wire three. The electrical control cabinet 35 determines the floor position of the passenger, and then drives the servo motor 23 through the wire one to drive the car frame 4 to move to the designated floor for operation. The control cabinet 35 supplies power to the transmitting end of the grating ruler module 31 through the wire two. After the transmitting end of the grating ruler module 31 irradiates the receiving end of the grating ruler module 31 on the car frame 4, the receiving end of the grating ruler module 31 feeds back a signal to the electrical control cabinet 35 through the wire seven. After receiving the feedback signal, the electrical control cabinet 35 opens the automatic door 14 through the wire six, and the passenger enters the car frame 4. The weighing module 33 transmits the weight signal to the electrical control cabinet 35 through the wire five. When the electrical control cabinet 35 determines that the passenger weight is within the safe working range of the car frame 4, the electrical control cabinet 35 controls the automatic door 14 to close through the wire six. The passenger selects the floor through the touch screen 45, and the touch screen 45 transmits the floor position to the electrical control cabinet 35 through the wire four. The electrical control cabinet 35 drives the servo motor 23 through the wire one, and the servo motor 23 drives the car frame 4 to reach the floor selected by the passenger. When the car frame 4 reaches the designated floor, the receiving end of the grating ruler module 31 is illuminated by its transmitting end, and the receiving end of the grating ruler module 31 feeds back a signal to the electrical control cabinet 35 through the wire seven. The electrical control cabinet 35 controls the automatic door 14 to open through the wire six, and the automatic door 14 closes after the passenger leaves the car frame 4. During the operation of the device, if there is an obstacle between the shaft frame 13 and the car frame 4, the obstacle squeezes the micro switch. After the micro switch is squeezed, it feeds back a signal to the control cabinet 35 through the wire eight, and the control cabinet 35 ends the power supply on the wire one, and shuts down the elevator in time to prevent accidents.

[0063] Among them, the electrical control cabinet 35 is specifically: NICE3000 type; the elevator call box 17 is specifically: TT-WH-0766 type; the grating ruler module 31 is specifically: HF-0640 type; the weighing module is specifically: GML670 type.

[0064] The beneficial effects of the above scheme are:

[0065] The servo motor 23, the grating ruler module 31, the elevator call box 17, the touch screen 45, the weighing module 33 and the automatic door 14 work in conjunction with the electrical control cabinet 35, which greatly improves the working efficiency of the elevator; the provision of the grating ruler module 31 and the weighing module 33 greatly improves the safety of passengers when using the elevator.

[0066] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
