Description

Technical Field

[0001] The present invention relates to the field of elevator devices, in particular to a guide device for a villa elevator. Background Art

[0002] At present, when the existing villa elevator is in operation, the box body performs lifting and lowering movements in the frame, and the box body and the frame are moved by a guide device. The guide device includes a slide rail vertically arranged on the frame and a slider fixed to the box body. The box body is lifted and lowered by sliding between the slider and the slide rail. However, the sliding has a large friction force, and the elevator is prone to vibration during operation, with a poor shock absorption effect. The vibration moment can easily cause the guide device to be subjected to a large force, which not only generates a large noise, but also increases the friction force between the slider and the slide rail. Long-term operation can easily cause the guide device to wear, deform or even be damaged. The guide device of the elevator needs to be maintained frequently, which reduces the life of the elevator guide device.

[0003] Chinese patent application number: 202020021252.3, provides an elevator slide rail guide rod, including a fixed plate and a slider, a connecting block fixedly connected to the middle of the top surface of the fixing plate, a fixed block fixedly connected to the center of the connecting block away from the fixing plate, a guide rod fixedly connected to the side of the fixing block away from the connecting block, a through hole is opened at the center of the guide rod, an oil-absorbing sponge is provided on the inner wall of the through hole, and a plurality of oil outlet holes are opened on one side of the inner wall of the through hole, a circular groove is opened on the bottom surface of the slider, the slider is slidably connected to the guide rod through the circular groove, the top surface of the slider is fixedly connected to the mounting plate, a plurality of fixing holes are opened on the edge of the top surface of the mounting plate, a plurality of heating wires are fixedly connected to the inside of the guide rod, an air guide hole is opened at the center of the connecting block, an air inlet nozzle is fixedly connected to the outer surface of the connecting block near the air guide hole, a plurality of cylinders are opened on one side of the interior of the fixing block, a piston rod is slidably connected to the interior of each of the cylinders, and an extrusion head is fixedly connected to one end of the piston rod. This device uses sliding friction for transportation. The elevator generates vibrations during operation, which may cause the friction between the slider and the guide rod to increase instantly. The elevator generates large vibrations and poor stability. The sliding friction is large, which can easily lead to wear and deformation between the slider and the guide rod. The wear resistance is poor and it is easy to generate loud noise. The service life of the slider and the guide rod is short and they need to be maintained and serviced frequently. Summary of the Invention

[0004] Therefore, in order to solve the above problems, the present invention proposes a guide device for a villa elevator, which solves the technical problems of poor wear resistance, poor shock absorption effect, high noise and short service life of elevator guide devices.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A guide device for a villa elevator includes two guide rail mechanisms vertically arranged on the elevator frame and at least two guide mechanisms arranged on the elevator box. The guide mechanisms can move along the guide rail mechanisms. The guide rail mechanisms include a fixed plate and at least one guide rod arranged on the fixed plate. The guide mechanism includes a mounting plate, at least one guide wheel rotatably arranged on the mounting plate, and at least one guide block sleeved on the guide rod. The guide wheel can roll against the guide rod, and the guide block can slide on the guide rod.

[0007] Further:

[0008] The mounting plate includes at least one rotating seat, the middle portion of which is rotatably connected to the mounting plate, and at least one guide wheel is respectively provided at the upper and lower ends of the rotating seat, and at least two guide wheels on each rotating seat abut against the same guide rod.

[0009] Both ends of the rotating seat are provided with inclined parts, the two inclined parts are inclined toward the guide rod, and the guide wheel is rotatably arranged on the inclined parts.

[0010] The guide device has a front side close to the elevator door and a back side facing away from the elevator door. Two guide mechanisms are slidably provided on each guide rail mechanism. The front side of at least one guide wheel of the upper guide mechanism abuts against the guide rod, and the back side of at least one guide wheel of the lower guide mechanism abuts against the guide rod.

[0011] There is a gap between the guide rod and the guide block.

[0012] The size of the gap is 0.74 mm to 1 mm.

[0013] The number of guide rods of each guide rail mechanism is two, the number of guide blocks on each guide mechanism is two, the number of guide wheels on each guide mechanism is two, and the two guide wheels are located between the two guide rods.

[0014] The outer edge of the guide wheel is an inwardly recessed annular arc groove, and the arc groove abuts against the guide rod.

[0015] The guide block is provided with a cylindrical sliding groove, the guide rod is passed through the sliding groove, and the guide block is provided with a clearance opening, which is connected to the sliding groove.

[0016] The inner wall of the sliding groove is detachably provided with a guide piece, the guide piece is made of a soft material, the guide piece is slidably sleeved on the guide rod, and there is a gap between the guide piece and the guide rod.

[0017] The villa elevator adopts a screw and a permanent magnet motor for lifting and lowering, and also includes a shock absorbing device, which includes at least one shock absorbing mechanism, which includes a base, a movable frame rotatably arranged on the base, a buffer wheel rotatably arranged on the movable frame, and an elastic mechanism provided between the base and the movable frame. The buffer wheel abuts against the screw, and small holes are respectively provided on the base and the movable frame. The elastic mechanism includes a bolt passing through two small holes and a buffer spring sleeved on the bolt. The diameter of the bolt is smaller than the diameter of the small hole. One end of the buffer spring abuts against the base, and the other end of the buffer spring abuts against the end of the bolt. A nut is provided at the other end of the bolt, and the nut abuts against the movable frame.

[0018] The shock absorbing device further comprises a base, a through hole is provided in the middle of the base, a screw rod is passed through the through hole, there are three shock absorbing mechanisms, and the buffer wheels of the three shock absorbing mechanisms are 120 degrees apart from each other.

[0019] By adopting the above technical solution, the beneficial effects of the present invention are:

[0020] The elevator of the present invention slides through the guide rail mechanism and the guide mechanism, and has a guiding function for the elevator to be lifted and lowered. Rolling friction is generated between the guide wheel and the guide rod, and sliding friction is generated between the guide block and the guide rod. The rolling friction is relatively small. The guide device of the present invention mainly uses a rolling mode, and the sliding mode is an auxiliary protection mode, which greatly reduces the friction of the guide device during the operation of the elevator, reduces the wear between the guide rail mechanism and the guide mechanism, and has good stability, low friction, and strong wear resistance when the elevator box is lifted and lowered, and reduces noise, thereby increasing the service life of the guide device; further, the middle part of the rotating seat is rotatably connected to the mounting plate, and at least one guide wheel is provided at the upper and lower ends of the rotating seat. When vibration occurs, one of the guide wheels is subjected to force When the vehicle moves in the direction away from the guide rod, the rotating seat is forced to rotate, causing the other guide wheel to move in the direction of the guide rod, and the guide rod exerts a force on the other guide wheel. Through the force of the rotating seat, the guide wheel moving in the direction away from the guide rod is pulled back. The two guide wheels interact with each other through the rotating seat, so that the two guide wheels can be firmly against the guide rod, and the guide wheels are not easy to separate from the guide rod for a short time due to vibration, ensuring that the guide wheels are in contact with the guide rod to generate rolling friction, preventing the guide wheels from not rotating, and the rotating seat has a slight buffering effect to prevent the guide wheels from being damaged by hard collision with the guide rod, so that the guiding effect is better; further, inclined parts are provided at both ends of the rotating seat, and the inclined parts enhance the strength of the rotating seat to prevent The swivel seat is deformed when subjected to excessive force, which makes the swivel seat have better buffering performance. When the inclined part is subjected to a large force, a small deformation can be generated, which is conducive to the inclined part returning to its original shape after deformation. Furthermore, the two guide rail mechanisms are respectively located at the rear edge of the elevator box body. Since the bottom of the elevator box body is subjected to a large force, the rear end of the bottom of the elevator box body tends to tilt backward, and the rear end of the top of the elevator body tends to tilt forward. Therefore, the back of at least one guide wheel of the lower guide mechanism abuts against the guide rod, and the front of at least one guide wheel of the upper guide mechanism abuts against the guide rod. The guide rod has a supporting function, and the acting force between the guide rod and the guide wheel has an anti-tilting function, which prevents the elevator box body from tilting and prevents the elevator from tilting. The elevator vibrates greatly during operation, making the elevator more stable during lifting and lowering, reducing noise, and facilitating the close fit between the guide rod and the guide wheel, which is conducive to the rolling of the guide wheel; further, there is a gap between the guide rod and the guide block, which reduces sliding friction between the guide rod and the guide block. The connection between the guide rod and the guide block mainly plays a protective role, reducing noise and reducing the resistance caused by sliding friction when the elevator is lifting and lowering, thereby realizing a guiding method with rolling friction as the main factor and sliding friction as the auxiliary protection; further, the outer edge of the guide wheel is an inwardly concave annular arc groove, and the guide rod is located in the arc groove. The arc groove has a certain limiting effect, making it difficult for the guide rod and the guide wheel to shift, making the elevator operation more stable;Furthermore, a clearance opening is provided on the guide block to facilitate the installation of the guide block and the guide rod, and to facilitate the installation of the guide plate. When the guide plate is used, no lubricating oil is required when the guide rod and the guide block slide and rub against each other, which is simple and practical. Furthermore, the elevator uses a screw to achieve lifting and lowering, which is prone to generating a lot of noise. The buffer wheel of the shock-absorbing mechanism abuts against the screw, which not only has a guiding function but also reduces the vibration of the screw and reduces the noise.

[0037] The number of the above-mentioned guide mechanisms 2 can also be two, three, four or even more, and is usually set to four, respectively, and is respectively provided at the side edges of the four corners of the elevator car body 3, and is set according to the specific situation. The number of guide wheels 22 on each guide mechanism 2 can be one, two, three or even more, and is set according to the specific situation. When each guide mechanism 2 is not provided with a rotating seat 210, when there are multiple guide wheels 22, each guide wheel 22 can be respectively abutted against two guide rods 12; when each guide mechanism 2 is provided with two rotating seats 210, the guide wheel 22 of one rotating seat 210 can be abutted against one guide rod 12, the guide wheel 22 of the other rotating seat 210 can be abutted against the other guide rod 12, or all guide wheels 22 can be abutted against the same guide rod 12; when each guide mechanism 2 is provided with more than two rotating seats 210, it can be set according to the specific situation.

[0038] The gap between the guide rod 12 and the guide block 23 is usually 0.74 mm to 1 mm, but can also be other values, which are set according to the specific situation. There may also be no gap between the guide rod 12 and the guide block 23, and sliding friction and rolling friction are used for guidance. Although this guiding method makes the elevator lifting more stable, it has large friction and loud noise.

[0039] The above-mentioned mounting plate 21 may also not be provided with a rotating seat 210, and the guide wheel 22 may be rotatably provided on the rotating seat 210. However, in this way, the guide wheel 22 may have sliding friction or the guide wheel 22 may not rotate, and the guiding effect is poor. It is set according to the specific situation.

[0040] The shock absorbing mechanism 4 on the above-mentioned shock absorbing device can be one, two, three or even more, and usually three are set. The present invention may not be provided with a shock absorbing device. The shock absorption and noise reduction effects of this structure are not as good as those of the shock absorbing device. The villa elevator of the present invention may not use a screw and a permanent magnet motor for lifting. Therefore, the present invention may not be provided with a shock absorbing device, and the specific setting may be based on the specific situation.

[0041] The elevator has a transverse direction parallel to the elevator door and perpendicular to the longitudinal direction of the elevator door, and the rotating shaft of the guide wheel 22 is transverse.

[0042] The villa elevator of the present invention may not adopt the structure of the elevator box 3, but may adopt the structure of the elevator box 3 with an L-shaped cross section, which is specifically set according to the situation.

[0043] The rotating seat 210 is in the shape of an elongated strip, and may also be in other structures, depending on the specific situation.

[0044] The guide sheet is made of a known material and may be a highly wear-resistant flexible plastic sliding sheet disclosed in Chinese Patent Application No. 201220256993.5. The material is known and will not be described in detail herein.

[0045] The screw and permanent magnet motor of the villa elevator of the present invention can adopt Chinese patent application number: 201920957696.5, which provides a direct drive structure of the lifting platform. It is a well-known device and will not be described in detail here.

[0046] The working mode of the present invention is:

[0047] When the villa elevator of the present invention is in lifting operation, the guide wheels 22 of the two lower guide mechanisms 2 abut against the guide rod 12 farther away from the elevator door, and the guide wheels 22 of the two upper guide mechanisms 2 abut against the guide rod 12 closer to the elevator door. The guide wheels 22 roll on the guide rod 12, and rolling friction occurs between the guide wheels 22 and the guide rod 12; when vibration occurs so that one of the guide wheels 22 is forced to move in the direction away from the guide rod 12, the rotating seat 210 is forced to rotate so that the other guide wheel 22 moves in the direction of the guide rod 12, and the guide rod 12 exerts a force on the other guide wheel 22. The force of the rotating seat 210 pulls back the guide wheel 22 in the direction away from the guide rod 12, and the two guide wheels 22 interact with each other through the rotating seat 210, so that the two guide wheels 22 can firmly abut against the guide rod 12, and the guide wheels 22 It is not easy to separate from the guide rod 12 in a short time due to vibration, ensuring that the guide wheel 22 contacts the guide rod 12 to generate rolling friction, preventing the guide wheel 22 from not rotating, and the mounting plate 21 can be slightly deformed, which has a buffering effect, preventing the guide wheel 22 from being damaged by a hard collision with the guide rod 12, making the guiding effect better; there is a gap between the guide piece and the guide rod 12, and no sliding friction occurs between the guide piece and the guide rod 12. When the elevator vibrates greatly, the guide piece and the guide rod 12 may contact and generate sliding friction. The connection between the guide block 23 and the guide rod 12 plays a protective role, realizing a guiding method with rolling friction as the main and sliding friction as the auxiliary; at the same time, the buffer wheel 43 of the shock absorbing mechanism 4 abuts against the screw, which not only has a guiding function, but also reduces the vibration of the screw, reduces noise, and allows the elevator car body 3 to be lifted and lowered stably.

[0048] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
