Description

Technical Field

[0001] This invention relates to the field of elevator technology, specifically to a machine-room-less three-door elevator with an anti-sway system. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves along at least two rigid tracks perpendicular to the horizontal plane or at an angle of less than 15° to the vertical. The traction ropes are connected to the car and counterweight at both ends, and are wound around the traction sheave and guide sheave. The traction motor, after being reduced in speed by a reducer, drives the traction sheave to rotate. The traction force generated by the friction between the traction ropes and the traction sheave achieves the lifting and lowering movement of the car and counterweight, thus achieving the transportation purpose. Modern elevators mainly consist of a traction machine (winch), guide rails, counterweight device, safety devices (such as speed governors, safety brakes, and buffers), signal control system, car, and landing doors. These components are installed in the building's hoistway and machine room, respectively.

[0003] The current three-door motors, due to the installation of three doors, prevent three-door elevators from using the square frame elevator slides commonly used in conveyor elevators. This causes instability in the elevator's center of gravity during use, resulting in tilting and swaying, and giving passengers a poor riding experience. Summary of the Invention

[0004] To address the problem of insufficient stability in the operation of current three-door elevators mentioned in the background art, the present invention aims to provide a machine-room-less three-door elevator with an anti-sway system.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a machine-room-less three-door elevator with an anti-sway system, comprising a car, two opposing straight beams, an upper beam plate, and a lower beam plate. Three door lintels are installed on the car, located on three adjacent sides of the car. The straight beams are located between the upper and lower beam plates. The two straight beams, the lower beam plate, and the upper beam plate form a frame. The frame is fitted with the car and is located diagonally on the car. A car floor is fitted to the underside of the car. A bracket is fixedly installed on the lower beam plate. Four second rubber pads are installed on the frame, located between the car floor and the bracket. A car top plate is fixedly installed on the car, and a car top reinforcing rib is installed on the car top plate. Two opposing first connecting rods are installed on the upper beam plate, located between the upper beam plate and the car top plate. Side wing plates are installed on both sides of the first connecting rods. A car top reinforcing rib is fixedly installed above the car top plate. A first rubber pad is installed between each side wing plate and the car top reinforcing rib. The four first rubber pads are arranged in a square.

[0006] Preferably, the car is equipped with a suspended ceiling, on which a lampshade panel is installed, and several downlights are installed. A ventilation window is also installed on the suspended ceiling.

[0007] Preferably, two support brackets are installed on the car, and the two support brackets are arranged opposite to each other.

[0008] Preferably, a wheel beam is installed on the upper beam plate in cooperation with a wheel beam fixing seat, and two sets of clamping plates are installed on the wheel beam. Between every two clamping plates, there is a car top anti-rope wheel. The two car top anti-rope wheels are arranged opposite each other and are located on both sides of the upper beam plate.

[0009] Preferably, the bracket is the same size as the car and is correspondingly arranged, and the four second rubber pads are located at the four corners of the bracket.

[0010] Preferably, a car bottom anti-sway device is installed under the car, a pressure sensor is installed on the car bottom, a control center is installed on the lower side of the bracket, the control center controls and connects to the car bottom anti-sway device, the control center is communicatively connected to the pressure sensor, the car bottom anti-sway device includes an anti-sway frame, and two oppositely arranged mounting plates are installed on the top of the anti-sway frame through two sets of second connecting rods.

[0011] Preferably, each of the mounting plates has a mounting hole, which is a stepped hole, and a snap-fit ​​groove is fixedly installed on the lower side of each mounting plate, which is configured to snap-fit ​​with the lower beam plate.

[0012] Preferably, the anti-sway frame is equipped with two opposing hydraulic mechanisms. The hydraulic mechanisms are fixedly connected to the second connecting rod via two opposing first brackets, and the hydraulic mechanisms are connected to the anti-sway frame via two opposing second brackets.

[0013] Preferably, the anti-sway frame is composed of four identical splicing frames. Each splicing frame has a sliding cavity, and both ends of the sliding cavity are fitted with a cap. Each hydraulic mechanism is configured to cooperate with two opposite splicing frames, and the hydraulic mechanism extends a first liquid pipe and a second liquid pipe. The first liquid pipe and the second liquid pipe are respectively connected to both ends of the sliding cavity. Each sliding cavity has a counterweight ball that slides in cooperation with it, and the sliding cavity is filled with hydraulic oil.

[0014] Preferably, the sliding cavity inside the splicing frame is divided into a descent stroke and a convergence stroke. The descent stroke is oriented in an arc downwards and the horizontal direction is the same as the direction of the wheel beam. The convergence stroke is oriented in an arc downwards and the two opposing convergence strokes are arranged opposite each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The present invention comprises two straight beams, a lower beam plate, and an upper beam plate forming a frame. The straight beams are connected to the slide grooves in the elevator shaft. Side wing plates are installed on the upper beam frame, and several first rubber pads are installed between the side wing plates and the car top plate. When passengers stand at the corner of the car bottom on the lower beam plate, a pressure is applied to the corresponding corner of the car. The pressure can be transmitted to the upper beam plate through the car top, and a balancing force is applied to the car through the upper beam plate. The pressure is also directly transmitted to the bracket, so that the lower beam plate also applies a balancing force to the car. The addition of the two balancing forces can prevent the car from shaking significantly during operation, thereby improving the riding experience of passengers.

[0017] 2. When in use, this invention can stabilize the car through the car bottom anti-sway device, preventing further shaking of the car. When in use, the car bottom anti-sway device monitors the standing position of passengers through pressure sensors on the car bottom. After detecting the standing position, the hydraulic mechanism controls the position of the counterweight ball in the splicing frame at the corresponding position, thereby stabilizing the center of gravity of the car and preventing shaking caused by an unstable center of gravity. The position of the counterweight ball in the splicing frame is divided into a descent stroke and a convergence stroke. When the counterweight ball is in the descent stroke, the center of gravity of the car will change. When the counterweight ball is in the convergence stroke and moves downward, the center of gravity of the car can change more quickly, which is used for smooth operation in emergency situations, preventing large-scale shaking of the car and improving the riding experience of passengers.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-8 As shown in the figure, this embodiment provides a machine room-less three-door elevator with an anti-sway system, including a car 101, two oppositely arranged straight beams 201, an upper beam plate 203, and a lower beam plate 202. Three door lintels 102 are installed on the car 101, and the three door lintels 102 are respectively located on three adjacent sides of the car 101. The straight beams 201 are located between the upper beam plate 203 and the lower beam plate 202. The two straight beams 201, the lower beam plate 202, and the upper beam plate 203 form a frame. The frame is configured to cooperate with the car 101. The frame is located on the diagonal of the car 101, which facilitates the installation of the three-door car 101.

[0029] A car floor 104 is installed on the lower side of the car 101. A bracket 103 is fixedly installed on the lower beam 202. Four second rubber pads 207 are installed on the bracket 103. The second rubber pads 207 are located between the car floor 104 and the bracket 103. A car top plate 105 is fixedly installed on the car 101. A car top reinforcing rib 209 is installed on the car top plate 105. Two opposing first connecting rods 204 are installed on the upper beam 203. The first connecting rods 204 are located between the upper beam 203 and the car top plate 105. Side wing plates 205 are installed on both sides of the first connecting rods 204. A car top reinforcing rib 209 is fixedly installed above the car top plate 105. A first rubber pad 206 is installed between each side wing plate 205 and the car top reinforcing rib 209. The four first rubber pads 206 are arranged in a square. The first rubber pads 206 can play a good buffering role and prevent the car 101 from shaking a large range.

[0030] The car 101 is equipped with a suspended ceiling 113, on which a lamp cover 110 is installed. Several downlights 111 are also installed on the suspended ceiling 113. A ventilation window 112 is also installed on the suspended ceiling 113. Two support brackets 108 are installed on the car 101, and the two support brackets 108 are arranged opposite to each other.

[0031] A wheel beam 106 is installed on the upper beam plate 203 in cooperation with the wheel beam fixing seat 109. Two sets of clamping plates 114 are installed on the wheel beam 106. Between every two clamping plates 114, there is a car top anti-rope wheel 107. The two car top anti-rope wheels 107 are arranged opposite each other and are located on both sides of the upper beam plate 203. The bracket 103 is the same size as the car 101 and is arranged accordingly. Four second rubber pads 207 are located at the four corners of the bracket 103. The second rubber pads 207 have the same function as the first rubber pads 206, which are used to provide good cushioning and prevent the car 101 from shaking in a large range.

[0032] The two straight beams 201 of the present invention, together with the lower beam plate 202 and the upper beam plate 203, form a frame. The straight beams 201 are connected to the slide groove of the elevator shaft. Side wing plates 205 are installed on the upper beam frame. Several first rubber pads 206 are installed between the side wing plates 205 and the car top plate 105. When passengers stand at the corner of the car bottom 104 of the lower beam plate 202, a pressure is applied to the corresponding corner of the car 101. The pressure can be transmitted to the upper beam plate 203 through the car top plate. The upper beam plate 203 applies a balancing force to the car 101. The pressure is also directly transmitted to the bracket 103, so that the lower beam plate 202 also applies a balancing force to the car 101. The addition of the two balancing forces can prevent the car 101 from shaking significantly during operation, thereby improving the riding experience of passengers.

[0033] A car bottom anti-sway device 300 is installed under the car 101. A pressure sensor is installed on the car bottom 104. A control center is installed on the underside of the bracket 103. The control center controls and connects to the car bottom anti-sway device 300. The control center is communicatively connected to the pressure sensor. The car bottom anti-sway device 300 includes an anti-sway frame 309. Two opposing mounting plates 301 are installed on the top of the anti-sway frame 309 through two sets of second connecting rods 303.

[0034] Each mounting plate 301 has a mounting hole 302, which is a stepped hole. Each mounting plate 301 has a snap-fit ​​groove 310 fixedly installed on its lower side. The snap-fit ​​groove 310 is snap-fitted with the lower beam plate 202. Two hydraulic mechanisms 304 are installed on the anti-sway frame 309. The hydraulic mechanisms 304 are fixedly connected to the second connecting rod 303 through two oppositely arranged first brackets 305. The hydraulic mechanisms 304 are connected to the anti-sway frame 309 through two oppositely arranged second brackets 306.

[0035] The anti-sway frame 309 consists of four identical splicing frames 314. Each splicing frame 314 has a sliding cavity 312, with caps 311 connected to both ends. Each sliding cavity 312 has interactively fitted components. Each hydraulic mechanism 304 is fitted with two opposing splicing frames 314, extending a first hydraulic pipe 307 and a second hydraulic pipe 308. The first hydraulic pipe 307 and the second hydraulic pipe 308 are respectively connected to both ends of the sliding cavity 312. Each sliding cavity 312 has a counterweight ball 313 that slides within it. The sliding cavity 312 is filled with hydraulic oil. The sliding cavity 312 inside the splicing frame 314 has a descending stroke and a closing stroke. The descending stroke... The direction of the approach stroke is downward in an arc and the horizontal direction is the same as that of the wheel beam 106. The direction of the approach stroke is downward in an arc and the two relative approach strokes are set opposite each other. The car bottom anti-sway device 300 can stabilize the car 101 and prevent the car 101 from shaking further. When the car bottom anti-sway device 300 is in use, the pressure sensor on the car bottom 104 monitors the standing position of the passengers. After the standing position is detected, the hydraulic mechanism 304 controls the position of the counterweight ball 313 in the splicing frame 314 at the corresponding position, thereby stabilizing the center of gravity of the car 101 and preventing the car 101 from shaking due to an unstable center of gravity.

[0036] It should be noted that the two straight beams 201 of the present invention, together with the lower beam plate 202 and the upper beam plate 203, form a frame. The straight beams 201 are connected to the slide grooves in the elevator shaft. Side wing plates 205 are installed on the upper beam frame. Several first rubber pads 206 are installed between the side wing plates 205 and the car top plate 105. When passengers stand at the corner of the car bottom 104 of the lower beam plate 202, pressure is applied to the corresponding corner of the car 101. The pressure can be transmitted to the upper beam plate 203 through the car top, and a balancing force is applied to the car 101 through the upper beam plate 203. The pressure will also be directly... The data is transmitted to the bracket 103, so that the lower beam 202 also applies a balancing force to the car 101. The addition of these two balancing forces prevents the car 101 from shaking significantly during operation, thereby improving the passenger experience. The car bottom anti-sway device 300 stabilizes the car 101 and prevents further shaking. When in use, the car bottom anti-sway device 300 monitors the standing position of the passengers through pressure sensors on the car bottom 104. After detecting the standing position, the hydraulic mechanism 304 controls the splicing at the corresponding position. The position of the counterweight ball 313 inside the frame 314 is adjusted by regulating the hydraulic oil flow at both ends of the counterweight ball 313 through the first hydraulic pipe 307 and the second hydraulic pipe 308. The sliding cavity 312 inside the splicing frame 314 is divided into a descent stroke and a convergence stroke. The descent stroke is arc-shaped downwards and horizontally aligned with the direction of the wheel beam 106. The convergence stroke is arc-shaped downwards, with the two opposing convergence strokes positioned opposite each other. The car body 101 can be stabilized by the car bottom anti-sway device 300. To prevent further shaking of the car 101 and stabilize its center of gravity, the counterweight ball 313 is positioned within the splicing frame 314 in two phases: a descent phase and a convergence phase. When the counterweight ball 313 is in the descent phase, the center of gravity of the car 101 changes. When the counterweight ball 313 is in the convergence phase and moves downward, the center of gravity of the car 101 changes more quickly. This ensures smooth operation in emergencies, prevents the car 101 from shaking excessively, and improves the passenger experience.
