Description

Technical Field

[0001] The present invention relates to the technical field of vertical elevators, and particularly to a vertical elevator device with guiding and positioning. Background Art

[0002] With the continuous development of the scientific and technological level, vertical elevators are increasingly applied to people's daily lives. Disabled-accessible vertical elevators are often installed at positions such as subway entrances and exits, underground sidewalks, pedestrian overpasses, and railway station entrances and exits. The disabled-accessible vertical elevator mainly consists of a guide rail, a lifting platform, a hydraulic cylinder, and a drive box. The vertical elevator can be directly installed on the cement floor through expansion bolts. The guide rail guides the ascent and descent of the lifting platform. The lifting platform is provided with a ramp plate and a handrail. The ramp plate facilitates the disabled to get on and off the lifting platform in a wheelchair. The lifting platform is provided with control buttons. After the disabled move to the lifting platform in a wheelchair and press the corresponding control buttons, the drive box controls the telescopic movement of the hydraulic cylinder, and the hydraulic cylinder drives the lifting platform to rise or fall, completing the vertical lifting and lowering of the lifting platform, making the travel of the disabled more convenient.

[0003] Currently, when the common disabled-accessible vertical elevator device is in use, the lifting platform relies on the hydraulic cylinder to drive the lifting platform to rise or fall. The hydraulic cylinder is installed on one side of the lifting platform. When the disabled are in a wheelchair on the lifting platform, there is no guiding structure to support and guide the lifting platform on the other side of the lifting platform. The lifting platform is only stressed on one side, and the two sides of the lifting platform are unevenly stressed, which easily causes eccentric wear of components such as the internal guide rail of the vertical elevator and reduces the service life of the vertical elevator. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] The present invention has the following beneficial effects:

[0017] (1) For the vertical lift device with guiding and positioning, by setting the vertical plate, the guiding mechanism connecting seat, and the second roller, during use, the vertical plate is installed on the cement floor through expansion bolts. The disabled person in a wheelchair is located on the lifting platform. The hydraulic cylinder of the lift body drives the lifting platform to rise or fall. The lifting platform drives the guiding mechanism to move along the inner wall of the chute. The first roller and the second roller are in contact with the inner wall of the chute. The first roller and the second roller rotate along the inner wall of the chute to guide the lifting platform. Through the guide rails in the lift body and the first roller and the second roller in the chute, both sides of the lifting platform are guided, so that the forces on both sides of the lifting platform are balanced, preventing uneven wear of the guide rails in the lift body, and achieving the effect of extending the service life of the lift body. It solves the problem that in the currently common barrier-free vertical lift devices for the disabled, the forces on both sides of the lifting platform are uneven, which easily causes uneven wear of components such as the inner guide rails of the vertical lift, reducing the service life of the vertical lift.

[0018] (2) The vertical lift device with guiding and positioning, by setting a square block, a first rack and an inclined tooth groove, during the ascending process of the lift table, the inclined inner wall of the inclined tooth groove presses the first rack and the second rack, causing the first rack and the second rack to move towards each other. When the inclined inner wall of the inclined tooth groove no longer presses the first rack and the second rack, the first rack and the second rack are inserted into the inclined tooth groove under the action of the spring force. As the lift table continuously ascends, the first rack and the second rack are continuously separated from or engaged with the inclined tooth groove. When engaged, the plane of the teeth on the first rack and the second rack contacts the plane of the inner wall of the inclined tooth groove, clamping the square block to prevent the square block from descending, thereby clamping the lift table to prevent the lift table from descending. When it is necessary to lower the lift table, push the movable block to separate the first rack and the second rack from the inclined tooth groove, and then press the control button on the lift table to lower the lift table.

[0019] (3) The vertical lift device with guiding and positioning, by setting a door stopper, rotating the square rod to make the first magnet block fit with the second magnet block to fix the square rod. The disabled person moves the wheelchair onto the lift table, and then rotates the square rod in the reverse direction to make the square rod stuck in the card slot of the lift table. The square rod plays a blocking role for the wheelchair to prevent the disabled person from falling off the lift table after sitting on the wheelchair and moving backward.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention.

[0031] Please refer to Figures 1-8, an embodiment of the present invention provides a technical solution: a vertical lift device with guiding and positioning, including a lift body 1 and a lift table 2. The back of the lift table 2 is close to the building. The front of the lift table 2 has square rods 1602 to block wheelchairs and prevent them from falling off the lift table 2. A vertical plate 3 is provided on the right side of the lift table 2. The vertical plate 3 can be fixed to the cement floor in the same fixing manner as the lift body 1. A square block 4 is fixedly connected to the right side of the lift table 2. There is a square block 4 at the middle position on the right side of the lift table 2. A chute 5 and a square groove 6 are respectively opened on the left side of the vertical plate 3. The number of chutes 5 is two, and the two chutes 5 are respectively located in the front and back of the square groove 6. A guiding mechanism 7 is arranged inside the chute 5. The guiding mechanism 7 moves up and down along the inner wall of the chute 5 to guide the lift table 2. The guiding mechanism 7 is fixedly connected to the right side of the lift table 2. The inner wall of the square groove 6 is movably connected to the surface of the square block 4. A first through groove 8 is opened on the front of the square block 4. A gear 9 is movably sleeved on the surface of a cylindrical pin fixedly connected to the inner wall of the first through groove 8. A cylindrical pin is fixedly connected at the middle position of the first through groove 8. The gear 9 is movably sleeved on the cylindrical pin. The inner wall of the first through groove 8 is respectively movably connected to the surfaces of a first rack 10 and a second rack 11. The first rack 10 is located in the front of the second rack 11. Tooth grooves 12 are respectively opened on the sides of the first rack 10 and the second rack 11 close to the gear 9. The tooth groove 12 of the first rack 10 is located below the gear 9, and the tooth groove 12 of the second rack 11 is located above the gear 9. The movement of the first rack 10 causes the second rack 11 to move synchronously through the gear 9. The tooth grooves 12 are meshed with the gear 9. Helical tooth grooves 13 are respectively opened on the front and back of the inner wall of the square groove 6. Both the first rack 10 and the second rack 11 are meshed with the helical tooth grooves 13. Elastic members 14 are respectively arranged at the top and bottom of the first rack 10. During the rising process of the lift table 2, the elastic force of the elastic members 14 causes the first rack 10 and the second rack 11 to continuously mesh with or separate from the helical tooth grooves 13. A separating mechanism 15 is arranged on the front of the first rack 10. A door stopper 16 is arranged on the inner wall of the lift table 2. The door stopper 16 is located in the front of the separating mechanism 15. A sign 17 is fixedly connected to the right side of the inner wall of the lift table 2. An indicating arrow and the words on how to use the movable block 1501 can be engraved on the sign 17. Pushing the movable block 1501 towards the back of the lift table 2 can separate the first rack 10 and the second rack 11 from the helical tooth grooves 13. Releasing the movable block 1501 can make the first rack 10 and the second rack 11 mesh with the helical tooth grooves 13.

[0032] Specifically, the two chutes 5 are symmetrically arranged with the vertical plane passing through the center of the square groove 6 as the symmetry plane.

[0033] In this implementation, the guiding mechanism 7 in the chute 5 is evenly stressed, preventing uneven wear of the guiding mechanism 7 in the chute 5.

[0034] Specifically, the guiding mechanism 7 includes a T-shaped rod 701 and a first roller 702. The T-shaped rod 701 is fixedly connected to the right side of the lifting platform 2. The surface of the T-shaped rod 701 is movably connected to the inner wall of the sliding groove 5. The first roller 702 is movably sleeved on the surface of the T-shaped rod 701, and the surface of the first roller 702 is movably connected to the right side inner wall of the sliding groove 5.

[0035] In this implementation scheme, the top view cross-section of the T-shaped rod 701 is T-shaped. The first roller 702 contacts the right side inner wall of the sliding groove 5. There are two guiding mechanisms 7 in the same sliding groove 5. The two guiding mechanisms 7 are composed of two T-shaped rods 701 and four first rollers 702. The T-shaped rod 701 is composed of a cross bar and a vertical bar. One end of the cross bar is connected to the right side of the lifting platform 2, and the other end is connected to the vertical bar. Two first rollers 702 are sleeved on one vertical bar. The left and right directions of the lifting platform 2 are guided by the guide rail of the elevator body 1 and the first roller 702 in the sliding groove 5 of the vertical plate 3.

[0036] Specifically, connecting seats 18 are fixedly connected to both ends of the T-shaped rod 701. A fixed shaft fixedly connected to the inner wall of the connecting seat 18 is movably sleeved with a second roller 19. The surface of the second roller 19 is movably connected to the inner wall of the sliding groove 5.

[0037] In this implementation scheme, the connecting seats 18 are fixedly connected to both ends of the vertical bar of the T-shaped rod 701. The second roller 19 contacts the front and back inner walls of the sliding groove 5 to guide the front and back directions of the lifting platform 2.

[0038] Specifically, the elastic member 14 includes a spring 1401, a connecting block 1402, and a groove 1403. The number of both the connecting block 1402 and the groove 1403 is two. The two connecting blocks 1402 are respectively fixedly connected to the top and bottom of the first rack 10. The two connecting blocks 1402 are respectively movably connected to the inner walls of the two grooves 1403. The two grooves 1403 are respectively opened at the top and bottom of the inner wall of the first through groove 8. One end of the spring 1401 is fixedly connected to the back of the connecting block 1402, and the other end of the spring 1401 is fixedly connected to the back of the inner wall of the groove 1403.

[0039] In this implementation scheme, during the rising process of the lifting platform 2, the first rack 10 drives the connecting block 1402 to continuously compress the spring 1401, causing the spring 1401 to be compressed. When the helical tooth groove 13 no longer presses the first rack 10, the elastic force of the spring 1401 causes the first rack 10 to engage with the helical tooth groove 13.

[0040] Specifically, the separation mechanism 15 includes a movable block 1501, a connecting rod 1502, and a second through groove 1503. The movable block 1501 is located on the front side of the sign 17. The right side of the movable block 1501 is movably connected to the right side of the inner wall of the lifting platform 2. The connecting rod 1502 is fixedly connected to the left side of the first rack 10. The second through groove 1503 is opened on the right side of the inner wall of the lifting platform 2. The second through groove 1503 communicates with the first through groove 8. The inner wall of the second through groove 1503 is movably connected to the surface of the connecting rod 1502. The right side of the movable block 1501 is fixedly connected to the left end of the connecting rod 1502.

[0041] In this embodiment, by pushing the movable block 1501, the movable block 1501 drives the first rack 10 to separate from the helical tooth groove 13 through the connecting rod 1502. The first rack 10 drives the second rack 11 to separate from the helical tooth groove 13 through the gear 9, and then the lifting platform 2 can descend. The second through groove 1503 provides space for the movement of the connecting rod 1502.

[0042] Specifically, the door stopper 16 includes a U-shaped rod 1601, a square rod 1602, and a card slot 1603. The U-shaped rod 1601 is fixedly connected to the right side of the inner wall of the lifting platform 2. The right end of the square rod 1602 is movably sleeved on the surface of the U-shaped rod 1601. The card slot 1603 is opened on the left side of the inner wall of the lifting platform 2. The surface of the square rod 1602 is movably connected to the inner wall of the card slot 1603.

[0043] In this embodiment, the square rod 1602 is stuck in the card slot 1603 on the left side of the inner wall of the lifting platform 2, and the square rod 1602 plays a role in blocking the wheelchair to prevent the wheelchair from falling off the lifting platform 2.

[0044] Specifically, a first magnet block 20 is fixedly connected to the top of the square rod 1602, and a second magnet block 21 is fixedly connected to the left side of the vertical plate 3.

[0045] In this embodiment, when the square rod 1602 rotates to the vertical state, the first magnet block 20 and the second magnet block 21 are attached to each other under the action of their own suction force to fix the square rod 1602 and prevent the square rod 1602 from rotating randomly.

[0046] When in use (during operation), the vertical plate 3 is installed on the cement floor by expansion bolts. Rotate the square rod 1602 to the right. The square rod 1602 rotates to the right with the U-shaped rod 1601 as the axis, so that the first magnet block 20 of the square rod 1602 fits with the second magnet block 21 of the vertical plate 3, fixing the square rod 1602. The disabled person moves the wheelchair onto the lifting platform, and then rotates the square rod 1602 in the reverse direction so that the square rod 1602 is stuck in the card slot 1603 of the lifting platform 2. The square rod 1602 plays a blocking role for the wheelchair to prevent the wheelchair from moving backward and falling off the lifting platform 2. Press the control button on the lifting platform 2, and the hydraulic cylinder of the elevator body 1 drives the lifting platform 2 to rise. The lifting platform 2 drives the guiding mechanism 7 and the square block 4 to move upward along the inner walls of the sliding groove 5 and the square groove 6 respectively. The first roller 702 and the second roller 19 are in contact with the inner wall of the sliding groove 5. The first roller 702 and the second roller 19 rotate along the inner wall of the sliding groove 5 to guide the lifting platform 2. When the first roller 702 rotates, it rotates with the vertical rod of the T-shaped rod 701 as the axis. When the second roller 19 rotates, it rotates with the fixed axis of the connecting seat 18 as the axis. The front and back of the inner wall of the sliding groove 5 are in contact with the second roller 19, and the right side of the inner wall of the sliding groove 5 is in contact with the first roller 702. Through the guiding of the first roller 702 and the second roller 19, both sides of the lifting platform 2 are guided. When the square block 4 moves upward along the inner wall of the square groove 6, the square block 4 drives the first rack 10 and the second rack 11 to move upward. The inclined surface of the inner wall of the helical tooth groove 13 presses the inclined surfaces of the teeth on the first rack 10 and the second rack 11, causing the first rack 10 and the second rack 11 to move towards each other. The movable block 1501 is fixedly connected to the first rack 10 through the connecting rod 1502. When the first rack 10 moves, it drives the movable block 1501 to move in the same direction through the connecting rod 1502. The first rack 10 and the second rack 11 are engaged with the gear 9 through the tooth groove 12. When the first rack 10 and the second rack 11 move towards each other, the first rack 10 drives the connecting block 1402 to squeeze the spring 1401 along the inner wall of the groove 1403. The spring 1401 is in a compressed state. The lifting platform 2 drives the first rack 10 and the second rack 11 to rise. When the inclined surface of the inner wall of the helical tooth groove 13 no longer presses the teeth of the first rack 10 and the second rack 11, the connecting block 1402 drives the first rack 10 to move in the reverse direction along the inner wall of the first through groove 8 under the elastic force of the spring 1401. The first rack 10 drives the gear 9 to rotate through the engagement of the tooth groove 12 on the first rack 10 with the gear 9. The rotation of the gear 9 drives the second rack 11 to move in the reverse direction through the engagement with the tooth groove 12 on the second rack 11, so that the first rack 10 and the second rack 11 are engaged with the helical tooth groove 13. The lifting platform 2 continuously rises, causing the first rack 10 and the second rack 11 to continuously engage and disengage with the helical tooth groove 13. When engaged, the flat surfaces of the teeth on the first rack 10 and the second rack 11 are in contact with the flat surface of the inner wall of the helical tooth groove 13, clamping the square block 4 to prevent the square block 4 from descending, thereby clamping the lifting platform 2.To prevent the lifting platform 2 from descending, when the lifting platform 2 is descending, the movable block 1501 needs to be pushed, so that the movable block 1501 drives the first rack 10 to move towards the back of the lifting platform 2 through the connecting rod 1502. The first rack 10 drives the connecting block 1402 to squeeze the spring 1401, and the spring 1401 is in a compressed state. The gear 9 rotates through the engagement of the tooth groove 12 on the first rack 10 and the gear 9. The rotation of the gear 9 drives the second rack 11 to move towards the front of the lifting platform 2 through the engagement with the tooth groove 12 on the second rack 11. The first rack 10 and the second rack 11 move towards each other and separate from the helical tooth groove 13. At this time, the control button on the lifting platform 2 can be pressed to make the lifting platform 2 descend. The lifting platform 2 drives the guiding mechanism 7 and the square block 4 to move downward along the inner walls of the sliding groove 5 and the square groove 6 respectively. After descending to the ground, the movable block 1501 is released. The connecting block 1402 drives the first rack 10 to move towards the front of the lifting platform 2 under the elastic force of the spring 1401 and engage with the helical tooth groove 13. The first rack 10 drives the second rack 11 to engage with the helical tooth groove 13 through the gear 9. During the descending process, the user always holds the movable block 1501. If the elevator body 1 fails and suddenly descends, the movable block 1501 can be immediately released during the descent to reduce the reaction time. The first rack 10 and the second rack 11 can engage with the helical tooth groove 13 to block the square block 4, thereby blocking the lifting platform 2 and preventing the lifting platform 2 from falling to the ground and causing personal injury. Through the guide rails in the elevator body 1 and the first roller 702 and the second roller 19 in the sliding groove 5, both sides of the lifting platform 2 are guided, so that the forces on both sides of the lifting platform 2 are balanced, preventing the guide rails in the elevator body 1 from being unevenly worn, and achieving the effect of extending the service life of the elevator body 1.
