Description

Technical Field

[0001] The invention relates to the technical field of circular elevators, in particular to a double-counterweight circular elevator. Background Art

[0002] A circular elevator is a specially designed elevator with a circular or partially circular car and shaft. This design is often used inside buildings as a feature or decorative element to provide passengers with a unique ride experience.

[0003] Existing circular elevators are different from common load-carrying elevators. Common load-carrying elevators usually use a single counterweight to reduce the gravity borne on one side of the motor, while circular elevators use two symmetrically distributed counterweights. The reason is that circular elevators are often used for sightseeing elevators. Setting counterweights door to door can easily affect the riding experience, while setting only one counterweight on the side can easily lead to insufficient stability. However, when a circular elevator uses two symmetrically distributed counterweights, first of all, there are very high requirements for the setting of the rotating pulley structure of the motor. It is necessary to ensure that the two steel cables can be raised and lowered smoothly and synchronously, and the gravity of the motor load must be much higher than that of a load-carrying elevator.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a double-counterweight circular elevator is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a double-counterweight circular elevator, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a double-counterweight circular elevator, comprising a guide rail bracket and a double counterweight assembly, the double counterweight assembly being fixed on the top of the guide rail bracket, the double counterweight assembly comprising a support frame, a drive motor, a first rotating pulley, a right guide wheel, a right counterweight frame, a right steel cable, a left guide wheel, a left counterweight frame, a second rotating pulley and a left steel cable, a drive motor being fixed on the side of the support frame, and the output end of the drive motor being connected to the first rotating pulley, a right guide wheel being arranged in parallel on the right side of the first rotating pulley, the right side of the outer wall of the guide rail bracket being slidably connected to the right counterweight frame, and the top of the right counterweight frame being connected to the right steel cable, a left guide wheel being arranged on the left side of the top of the guide rail bracket, and the left counterweight frame being slidably connected to the left side of the outer wall of the guide rail bracket, the top of the support frame being rotatably connected to the second rotating pulley, the top of the left counterweight frame being fixed with a left steel cable, the inner side of the guide rail bracket being slidably connected to a gantry frame, and a car being fixed on the surface of the gantry frame.

[0007] Furthermore, the end of the right steel cable away from the right counterweight frame passes through the right guide wheel and the first rotating pulley and is connected to the top of the gantry frame, and the end of the left steel cable away from the left counterweight frame passes through the left guide wheel and the second rotating pulley and is connected to the top of the gantry frame.

[0008] Furthermore, the side of the car close to the gantry frame is planar, and a car door is provided on the side of the car close to the gantry frame, and the gantry frame is in a U-shaped structure.

[0009] Furthermore, an anti-falling buffer component is arranged below the car, and the anti-falling buffer component includes a valve chassis and an air pump. The valve chassis is arranged at the bottom of the elevator shaft, and air pumps are arranged on both sides of the valve chassis.

[0010] Furthermore, the anti-falling buffer component also includes a buffer airbag, and the surface of the valve chassis is provided with a buffer airbag.

[0011] Furthermore, the anti-fall buffer assembly also includes a flange and an annular sealing gasket. The buffer airbags are fixedly connected by the flange, and an annular sealing gasket is arranged between the flanges.

[0012] Furthermore, the anti-falling buffer component also includes an air pressure sensor, and the air pressure sensor is arranged inside the buffer airbag.

[0013] Furthermore, the anti-fall buffer assembly also includes a limiting ring, and the limiting ring is equidistantly sleeved on the outside of the buffer airbag.

[0014] Furthermore, the anti-fall buffer assembly also includes a connecting rope, and the connecting rope is fixed on the surface of the limiting ring.

[0015] Furthermore, the anti-falling buffer component also includes sliding wheels, and sliding wheels are arranged on both sides of the bottom of the flange, and the buffer airbag and the flange are slidably connected to the inner side surface of the guide rail bracket through the sliding wheels.

[0016] The present invention provides a double-counterweight circular elevator, which has the following beneficial effects:

[0017] 1. In the double-counterweight circular elevator, the second rotating pulley and the first rotating pulley do not contact each other, and the second rotating pulley is not connected to the driving motor. When the driving motor is started, the first rotating pulley only bears the weight of the right counterweight frame, while the second rotating pulley and the supporting frame bear the weight of the left counterweight frame for the first rotating pulley and the driving motor. Therefore, it is beneficial to reduce the load of the driving motor and its first rotating pulley, so as to extend the service life of the driving motor, and does not affect the normal lifting and lowering of the car.

[0018] 2. In this double-counterweight circular elevator, the cushion airbag is retracted and expanded to always adapt to the distance between the bottom of the car and the bottom of the elevator shaft, and the internal air pressure of the cushion airbag is always kept within a constant threshold by controlling the opening and closing of the air pump and the valve inside the valve chassis. Therefore, when the car falls due to a malfunction and the brake pads do not take effect in time, the internal valve of the valve chassis closes, and the cushion airbag is compressed by the falling car until the cushion airbag can no longer be compressed due to its internal air pressure. At this time, the falling of the car stops. Therefore, the cushion airbag can greatly shorten the falling distance of the car and protect the safety of the people inside the car.

[0019] 3. For this double-counterweight circular elevator, the cushion airbag expands and contracts when the car is rising or falling normally. At this time, the connecting rope becomes loose or tight as the cushion airbag expands and contracts, so that the limiting ring on the outside of the connecting rope is always mounted on the outside of the cushion airbag and adapts to the expansion and contraction of the cushion airbag. Therefore, when the cushion airbag is compressed due to the falling of the car, the expansion range of the cushion airbag is limited to the inside of the limiting ring, thereby preventing the cushion airbag from being damaged due to contact and friction with other components inside the elevator shaft due to excessive expansion due to compression.

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 6 As shown, the present invention provides a technical solution: a double-counterweight circular elevator, comprising a guide rail bracket 1 and a double counterweight assembly 2, the double counterweight assembly 2 is fixed to the top of the guide rail bracket 1, the double counterweight assembly 2 comprises a support frame 201, a drive motor 202, a first rotating pulley 203, a right guide wheel 204, a right counterweight frame 205, a right steel cable 206, a left guide wheel 207, a left counterweight frame 208, a second rotating pulley 209 and a left steel cable 210, a drive motor 202 is fixed to the side of the support frame 201, and the output end of the drive motor 202 is connected to the first rotating pulley 203, and the right side of the first rotating pulley 203 is parallelly arranged with a right guide wheel 204, the right side of the outer wall of the guide rail bracket 1 is slidably connected to the right counterweight frame 205, and the top of the right counterweight frame 205 is connected to the right steel cable 206, and the left side of the top of the guide rail bracket 1 A left guide wheel 207 is provided, and a left counterweight frame 208 is slidably connected to the left side of the outer wall of the guide rail bracket 1, a second rotating pulley 209 is rotatably connected to the top of the support frame 201, a left steel cable 210 is fixed to the top of the left counterweight frame 208, a gantry frame 3 is slidably connected to the inner side of the guide rail bracket 1, and a car 4 is fixed to the surface of the gantry frame 3, the end of the right steel cable 206 away from the right counterweight frame 205 passes through the right guide wheel 204 and the first rotating pulley 203 and is connected to the top of the gantry frame 3, and the end of the left steel cable 210 away from the left counterweight frame 208 passes through the left guide wheel 207 and the second rotating pulley 209 and is connected to the top of the gantry frame 3, the side of the car 4 close to the gantry frame 3 is planar, and a car door is provided on the side of the car 4 close to the gantry frame 3, and the gantry frame 3 is a U-shaped structure;

[0029] The specific operation is as follows: the bottom end of the right steel cable 206 is fixedly connected to the top of the right counterweight frame 205, and the top of the right steel cable 206 passes through the right guide wheel 204 and the surface of the first rotating pulley 203 to realize turning, until the end of the right steel cable 206 away from the right counterweight frame 205 is fixed to the top of the gantry frame 3, and the bottom end of the left steel cable 210 is fixedly connected to the top of the left counterweight frame 208, and the top end of the left steel cable 210 passes through the left guide wheel 207 and the second rotating pulley 209 to turn and is fixed to the top of the gantry frame 3, and the second rotating pulley 209 and the first rotating pulley 203 do not contact each other, and the second rotating pulley 209 is not connected to the drive motor 202;

[0030] The first rotating pulley 203 is driven by the driving motor 202 to rotate counterclockwise so that the top of the right steel cable 206 is released downward, so that the car 4 slides and descends along the inner side of the guide rail bracket 1. When the car 4 descends, the top of the left steel cable 210 is subjected to force. At this time, the second rotating pulley 209 is forced to rotate clockwise, so that as the car 4 descends, the left counterweight frame 208 and the right counterweight frame 205 rise at the same time, so that the car 4 descends stably. Similarly, when the driving motor 202 drives the first rotating pulley 203 to rotate clockwise At this time, the second rotating pulley 209 is forced to rotate counterclockwise, so the car 4 is carried up through the left steel cable 210 and the right steel cable 206, wherein the second rotating pulley 209 is rotatably connected to the top of the support frame 201, so the second rotating pulley 209 and the support frame 201 bear the weight of the left counterweight frame 208 for the first rotating pulley 203 and the drive motor 202, thereby helping to reduce the load of the drive motor 202 and its first rotating pulley 203, so as to extend the service life of the drive motor 202.

[0031] like Figure 1-Figure 6 As shown, an anti-falling buffer component 5 is arranged below the car 4, and the anti-falling buffer component 5 includes a valve chassis 501 and an air pump 502. The valve chassis 501 is arranged at the bottom of the elevator shaft, and the air pumps 502 are arranged on both sides of the valve chassis 501. The anti-falling buffer component 5 also includes a buffer airbag 503, and the surface of the valve chassis 501 is provided with the buffer airbag 503. The anti-falling buffer component 5 also includes a flange 504 and an annular sealing gasket 505. The buffer airbags 503 are fixedly connected by the flange 504, and the annular sealing gasket 505 is arranged between the flanges 504. 5. The anti-falling buffer component 5 also includes an air pressure sensor, the air pressure sensor is arranged inside the buffer airbag 503, the anti-falling buffer component 5 also includes a limiting ring 506, the outer part of the buffer airbag 503 is equidistantly sleeved with limiting rings 506, the anti-falling buffer component 5 also includes a connecting rope 507, the connecting rope 507 is fixed on the surface of the limiting ring 506, the anti-falling buffer component 5 also includes a sliding wheel 508, the sliding wheels 508 are arranged on both sides of the bottom of the flange 504, and the buffer airbag 503 and the flange 504 are slidably connected to the inner side of the guide rail bracket 1 through the sliding wheel 508;

[0032] The specific operation is as follows: the anti-falling buffer component 5 is suitable for medium- and high-rise buildings, specifically buildings with six to twelve floors. The buffer airbags 503 are made of rubber material. The buffer airbags 503 are fixedly connected by flanges 504, and the sealing of the connection is strengthened by an annular sealing gasket 505, so that the insides of the buffer airbags 503 are interconnected, and the buffer airbag 503 at the bottom is connected to the valve chassis 501, and the flange 504 is slidably connected to the inner side of the guide rail bracket 1 through the sliding wheels 508 on both sides thereof;

[0033] When the car 4 is raised or lowered, its bottom will drive the cushion airbag 503 to expand and contract accordingly to always adapt to the distance between the bottom of the car 4 and the bottom of the elevator shaft. When the cushion airbag 503 expands and contracts, the air pressure sensor inside it monitors the air pressure value in real time, and controls the air pressure inside the cushion airbag 503 to always be within a constant threshold through the opening and closing of the air pump 502 and the valve inside the valve chassis 501. Therefore, when the car 4 falls due to a malfunction and the brake pads do not take effect in time, the valve inside the valve chassis 501 is closed, and the car 4 compresses the cushion airbag 503 due to the falling until the cushion airbag 503 cannot continue to be compressed due to the internal air pressure. At this time, the falling of the car 4 stops. Therefore, the cushion airbag 503 can greatly shorten the falling distance of the car 4, thereby protecting the safety of the people inside the car 4.

[0034] Secondly, when the car 4 rises and falls normally, the cushion airbag 503 expands and contracts accordingly. At this time, the connecting rope 507 becomes loose or tight as the cushion airbag 503 expands and contracts, so that the limiting ring 506 outside the connecting rope 507 is always mounted on the outside of the cushion airbag 503 and adapts to the expansion and contraction of the cushion airbag 503. Therefore, when the car 4 falls and the cushion airbag 503 is compressed, the expansion range of the cushion airbag 503 is limited to the inside of the limiting ring 506, thereby preventing the cushion airbag 503 from being damaged by contact and friction with other components inside the elevator shaft due to excessive expansion due to compression.

[0035] In summary, when the double-counterweight circular elevator is in use, the first rotating pulley 203 is driven counterclockwise by the driving motor 202 to release the top end of the right steel cable 206 downward, so that the car 4 slides and descends along the inner side of the guide rail bracket 1, and when the car 4 descends, the top end of the left steel cable 210 is subjected to force, and at this time, the second rotating pulley 209 is forced to rotate clockwise, so that as the car 4 descends, the left counterweight frame 208 and the right counterweight frame 205 rise at the same time, so that the car 4 descends stably. Similarly, when the driving motor 202 drives the first rotating pulley 203 to rotate clockwise, the second rotating pulley 209 is forced to rotate counterclockwise, so that the car 4 is carried up by the left steel cable 210 and the right steel cable 206;

[0036] When the car 4 is raised or lowered, its bottom will drive the cushion airbag 503 to expand and contract accordingly to always adapt to the distance between the bottom of the car 4 and the bottom of the elevator shaft. When the cushion airbag 503 is expanded and contracted, the air pressure sensor inside it monitors the air pressure value in real time, and controls the air pressure inside the cushion airbag 503 to always be within a constant threshold through the opening and closing of the air pump 502 and the valve inside the valve chassis 501. Therefore, when the car 4 falls due to a malfunction and the brake pads do not take effect in time, the valve inside the valve chassis 501 is closed, and the car 4 compresses the cushion airbag 503 due to the falling until the cushion airbag 503 can no longer be compressed due to the air pressure inside it, at which time the falling of the car 4 stops;

[0037] When the car 4 rises and falls normally, the cushion airbag 503 expands and contracts accordingly. At this time, the connecting rope 507 becomes loose or tight as the cushion airbag 503 expands and contracts, so that the limiting ring 506 outside the connecting rope 507 is always mounted on the outside of the cushion airbag 503 and adapts to the expansion and contraction of the cushion airbag 503. Therefore, when the car 4 falls and the cushion airbag 503 is compressed, the expansion range of the cushion airbag 503 is limited to the inside of the limiting ring 506.

[0038] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
