Description

Technical Field

[0001] The invention relates to a lift, in particular to a lift with an automatic telescopic platform. Background Art

[0002] An elevator, also known as a cage, is a device used for vertical transportation of personnel or goods. It is widely used in construction, mining, ship repair and other fields. Its basic structure includes a cage body, a lifting mechanism, a control system and a safety device. The electric motor drives the drive drum through a reducer to wind or release the wire rope to achieve the lifting of the cage. However, due to architectural planning reasons, some buildings are not straight during construction, which results in a certain distance between the vertically installed elevator and the construction opening of the floor. If workers directly cross this distance to transport materials and there are certain hidden dangers during construction.

[0003] Traditional operations involve setting up a support plate between two locations and fixing the support plate between the elevator and the building. However, during high-altitude construction, it is easily affected by wind and vibration during cargo transportation. Therefore, the prior art provides a sliding plate in the elevator, which can slide out when in use and retract when not in use. Although the plate is installed in the cage of the cage, it is difficult to ensure its stability after extending a long length. The front end is easy to fall down and the rear end is easy to warp and deform, which poses a certain safety hazard to cargo and workers when entering and exiting, making it difficult to carry out safe construction.

[0004] Therefore, this case aims to provide a lift with an automatic retractable platform, which can slide out stably when needed, and can achieve a stable effect both in the sliding out stage and in the fixed structure, thereby ensuring the safety of goods and workers between the cage and the building and improving construction safety.

An anti-warping component is arranged on the end of the outer side of the extension platform away from the building, and a guide wheel is arranged on the inner side of the guide frame close to the building. When the extension platform moves outward, the anti-warping component moves along the guide frame, and when the extension platform moves along the guide frame, the guide wheel rotates along the outer side of the extension platform; The side limit top position structure includes a lateral pushing member arranged between the cage frame and the guide frame, and a transverse blocking frame is arranged on the side of the lateral pushing member close to the extension platform, and a pressure dividing assembly is installed on the transverse blocking frame.

[0007] As a further improvement, the driving structure includes a reducer assembly locked on the cage frame, a driving gear fixed to the reducer assembly, the driving gear meshing with the mating part, and when the reducer assembly drives the driving gear to rotate, the mating part moves forward or backward, thereby driving the extension platform to move forward or backward.

[0008] As a further improvement, the guide frame is an I-beam structure, and the matching piece is a rack.

[0009] As a further improvement, the extension platform includes a movable frame slidably arranged on the inner side of the I-beam structure, a protective frame is arranged on the top of the movable frame, a side guide is arranged on the outer side of the movable frame, the side guide includes an inner recess installed on the side of the movable frame, and a side guide wheel is arranged on the inner side of the inner recess.

[0010] As a further improvement, an accommodating guide groove is opened on the outer side of the movable frame, and the anti-warping assembly includes an upper safety guide wheel locked on the upper half of the outer side of the movable frame, and a lower safety guide wheel is movably installed on the lower half of the outer side of the movable frame, and the upper safety guide wheels are in contact with the inner part of the short plate of the I-beam structure through the accommodating guide groove.

[0011] As a further improvement, the lateral pushing member includes a pushing member arranged on the bottom of the cage frame, one side of the pushing member is connected to the external oil circuit, a pushing frame is connected to the output end of the pushing member, and the end of the pushing frame is connected to the transverse barrier frame.

[0012] As a further improvement, the pushing member includes two sets of ejection rods, the pushing frame includes a long connecting handle connected to the lower end ejection rod, the upper end of the long connecting handle is equipped with a short connecting handle through a connecting arm, and the short connecting handle is connected to the transverse blocking frame.

[0013] As a further improvement, the transverse barrier frame includes a plurality of embedded strips connected to a short connecting handle, wherein the width of the embedded strips is equal to the spacing between the tooth tips on the rack, and the top surfaces of all the embedded strips are connected to an integrated board, which is attached to the outer side of the extension platform.

[0014] As a further improvement, the pressure dividing assembly includes a pneumatic push rod arranged on the transverse blocking frame, a pressure dividing plate is arranged on the top of the pneumatic push rod, and the lower ends of both sides of the pressure dividing plate are connected to the transverse blocking frame through springs.

[0015] As a further improvement, an inner groove is provided on the bottom plate inside the cage frame, a receiving seat is provided on the side of the movable frame away from the building, a reverse thrust component is arranged in the inner groove, the reverse thrust component includes an oblique push-pull member arranged inside the inner groove, a push rod is arranged on the output end of the oblique push-pull member, the oblique push-pull member is electrically connected to the pushing member, and the oblique push-pull member is pushed out when the pushing member is pushed out.

[0016] The beneficial effects of the present invention are: Existing elevators are also provided with platforms that can be connected to buildings, but usually the platform is only pushed out to the connection end position of the building through the driving structure. The stability of the entire platform is actually poor. In the process of advancement and retraction, it is actually easy to fall down or be unable to retract due to lack of support and guidance. Therefore, the present invention, through the provided guiding anti-falling structure, can firstly push out the extended platform through the cooperation of the driving structure and the matching parts, and in the process of pushing out, an anti-warping component is provided on the extended platform, and the anti-warping component always cooperates with the guide frame to prevent the rear end of the extended platform from tilting up, and a guide wheel is provided at the end of the guide frame close to the building to support the front end of the extended extended platform to prevent the extended platform from falling down after extension. Through the cooperation of one static and one dynamic, the extended platform can maintain a horizontal moving state whether in the extension or retraction stage, so that the goods and personnel located at the upper end can be in a stable moving state, thereby improving the safety of construction.

[0017] In order to ensure the stability of the driving structure and avoid insufficient power of the driving structure or too fast extension and retraction speed, the driving structure of the present invention is a structure similar to a reducer, which is matched with a driving gear driving fitting, so that the entire driving process is more stable, and the extension platform is more stable during the extension and retraction process.

[0018] In order to provide space for the installation of the anti-warping component and space for the guide wheel to move, the guide frame of the present invention is an I-beam structure, so that there is a certain installation space on the inside, and a certain gap between the outside and the cage frame to install the side limit top position structure and the drive structure.

[0019] In the process of the entire extended platform moving forward or backward, the goods and people need to move along with it, so the movement of the extended platform needs to be relatively stable. Therefore, the extended platform of the present invention not only has a protection frame at the upper end of the movable frame to protect the goods and people more safely after the movable frame is extended, but also has side guides at the bottom of the movable frame. The side guides are used to regulate the left and right lateral movement angles of the movable frame, thereby making the movement of the movable frame more stable and less prone to jamming due to incorrect angles.

[0020] During the outward extension process of the extended platform, the movable frame will gradually become suspended in the air, which may cause the top to be heavy and the entire movable frame to tilt. Therefore, the present invention provides an anti-tilt assembly, and respectively provides an upper safety guide wheel and a lower safety guide wheel. Whether the movable frame is tilted up or pressed down, it can have a good limiting and guiding effect, so that the movable frame can achieve the effect of horizontal movement.

[0021] During the process of cooperation between the driving structure and the matching parts, as the extension platform gets closer to the building, the suspended part of the extension platform increases more and more, until the extension platform reaches the contact surface of the building, the middle part of the entire extension platform is suspended, which poses a great test to the stability of the driving structure and the matching parts. Therefore, the present invention adds a side limit top position structure on the basis of the guide anti-fall structure, so that after the extension platform reaches the specified position, the matching parts and the driving structure can be limited by the transverse barrier frame, so as to avoid the extension platform from moving back and forth or shaking during the movement of goods and personnel, and after the transverse barrier frame is pushed out, the top of the extension platform can be supported and pressured by the pressure dividing assembly, so as to avoid sudden weight increase and damage to the driving structure, thereby making the entire retraction process more stable.

[0022] The mating member and the driving structure actually utilize the method of cooperating with the gear rack. When subjected to a back impact force or a forward swing force, the two are easily forced to move. Therefore, the present invention introduces a lateral pushing member to interfere, and directly interferes through a hydraulically driven pushing member to avoid passive movement of the rack.

[0023] In order to avoid a relatively single force point when the pushing member is pushed, the present invention divides the pushing frame driven by the pushing member into a multi-section handle-shaped structure, so that the tearing force can be segmented into different areas when the pushing frame is subjected to force, avoiding direct disconnection at the connection position between the pushing frame and the pushing member, and unloading the force at multiple points.

[0024] In the process of the horizontal barrier frame rigidly blocking the rack, if it is only set as a single structure, it is easy to deform and break due to the thin contact end. Therefore, the horizontal barrier frame of the present invention is set as a multi-section embedded strip, and all the embedded strips are connected by an integrated board, which not only makes the embedded strips become one, but also can provide a certain installation space for the pressure divider component, thereby improving the horizontal barrier frame and better utilizing the space.

[0025] The purpose of setting the pressure-dividing component is that when goods and people enter or leave the elevator, the load will change, which will have a greater impact on the driving structure, making it easy for the teeth to deform and cause discontinuous conduction during subsequent use, causing the platform to feel jerky. Therefore, the present invention sets a pressure-dividing component to provide support on both sides of the driving structure after the driving structure stops, thereby alleviating the pressure on the driving structure when goods and people pass through, and thus avoiding deformation of this position after bearing a large amount of load.

[0026] At the rear end of the movable frame, although there is a horizontal blocking frame in the middle, most accidents are caused by the fall of goods or personnel due to the retreat of the platform. Therefore, the present invention arranges a reverse thrust component on the cage frame, so that the oblique push-pull member can be pushed out after the movable frame is pushed out, thereby supporting the entire movable frame from the rear end to prevent the extended platform from sliding back. Combined with the horizontal blocking frame in the middle, the extended platform can be in a stable state during the entire construction process, so that the goods and personnel are more stable in the process of going back and forth between the building and the elevator.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] Reference Figure 1 to Figure 7As shown, a lift with an automatic telescopic platform comprises a cage frame 10 that cooperates with a standard section, a guide frame 20 is arranged on the inner side of the cage frame 10, an extension platform 30 is slidably installed on the inner side of the guide frame 20, and the extension platform 30 can move to the contact surface of the opposite building, and the lift also comprises: a guide anti-falling structure 40, a driving structure 41 is arranged on the outer side of the guide frame 20, a matching piece 42 is arranged on the outer side of the extension platform 30, and when the driving structure 41 is driven, the matching piece 42 is driven to move forward and backward, thereby driving the extension platform 30 to move forward and backward, an anti-warping component 43 is arranged on the outer side of the extension platform 30 away from the building, and a guide is arranged on the inner side of the guide frame 20 close to the building. The guide wheel 44, when the extension platform 30 moves outward, the anti-warping component 43 moves along the guide frame 20, and when the extension platform 30 moves along the guide frame 20, the guide wheel 44 rotates along the outer side of the extension platform 30; the side limit top position structure 50, including a lateral pushing member 51 arranged between the cage frame 10 and the guide frame 20, the lateral pushing member 51 is provided with a transverse blocking frame 52 on the side close to the extension platform 30, and a pressure dividing component 53 is installed on the transverse blocking frame 52. When the extension platform 30 reaches the specified position, the lateral pushing member 51 pushes the transverse blocking frame 52 out and places it horizontally on the matching member 42, and the pressure dividing component 53 is pushed out and pressed on the inner edge of the outer side of the extension platform 30.

[0039] During use, the driving structure 41 drives the matching member 42 to move, so that the extension platform 30 can slide in the guide frame 20, so that the extension platform 30 can be docked with the building platform or retracted into the cage frame 10.

[0040] Existing elevators are also provided with platforms that can be connected to buildings, but usually the platform is pushed out to the connection end position of the building only through the driving structure. The stability of the entire platform is actually poor. In the process of advancement and retraction, it is actually easy to fall down or be unable to retract due to lack of support and guidance. Therefore, the present invention, through the provided guiding anti-falling structure 40, can firstly push out the extension platform 30 through the cooperation of the driving structure 41 and the matching piece 42, and during the pushing process, an anti-warping component 43 is provided on the extension platform 30, and the anti-warping component 43 always cooperates with the guide frame 20 to prevent the rear end of the extension platform 30 from tilting up, and a guide wheel 44 is provided at the end of the guide frame 20 close to the building to support the front end of the extended extension platform 30 to prevent the extended platform 30 from falling down after being extended, so that through the cooperation of one static and one dynamic, the extension platform 30 can maintain a horizontal moving state whether in the extension or retraction stage, so that the goods and personnel located at the upper end can be in a stable moving state, thereby improving the safety of construction.

[0041] In order to ensure the stability of the driving structure 41 and avoid insufficient power of the driving structure 41 or too fast extension and retraction speed, the driving structure 41 of this embodiment includes a reducer assembly 411 locked on the cage frame 10, and a driving gear 412 is fixedly connected to the reducer assembly 411, and the driving gear 412 is meshed with the matching piece 42. When the reducer assembly 411 drives the driving gear 412 to rotate, the matching piece 42 moves forward or backward, thereby driving the extension platform 30 to move forward or backward. The driving structure 41 is a structure similar to a reducer, and is matched with the driving gear 412 to drive the matching piece 42, so that the entire driving process is more stable, and the extension platform 30 is more stable during the extension and extension process.

[0042] In order to provide space for the anti-warping component 43 to be installed and space for the guide wheel 44 to move, the guide frame 20 of this embodiment is an I-beam structure, and the matching piece 42 is a rack. Since the guide frame 20 is an I-beam structure, it can have a certain installation space on the inside, and a certain gap between the cage frame 10 and the outside to install the side limit top position structure 50 and the drive structure 41.

[0043] The extension platform 30 has a plurality of side guides 33 disposed on the bottom of the extension platform 31, and a plurality of side guides 33 are disposed on the bottom of the extension platform 31.

[0044] During the outward extension process of the extended platform 30, since the movable frame 31 will gradually become suspended in the air, it is easy to become top-heavy and cause the entire movable frame 31 to tilt. Therefore, a receiving guide groove is provided on the outer side of the movable frame 31 of this embodiment, and the anti-tilting component 43 includes an upper safety guide wheel 431 locked on the upper half of the outer side of the movable frame 31, and a lower safety guide wheel 432 is movably installed on the lower half of the outer side of the movable frame 31. The upper safety guide wheels 431 are in contact with the inner part of the short plate of the I-beam structure through the receiving guide groove. Through the anti-tilting component 43, the upper safety guide wheels 431 and the lower safety guide wheels 432 are respectively provided, so that whether the movable frame 31 is tilted up or pressed down, it can play a good limiting and guiding effect, so that the movable frame 31 can achieve the effect of horizontal movement.

[0045] During the cooperation between the driving structure 41 and the matching piece 42, as the extension platform 30 gets closer to the building, the suspended part of the extension platform 30 increases more and more, until the extension platform 30 reaches the contact surface of the building, the middle part of the entire extension platform 30 is suspended, which greatly tests the stability of the driving structure 41 and the matching piece 42. Therefore, the present invention adds a side limit top position structure 50 on the basis of the guide anti-fall structure 40, so that after the extension platform 30 reaches the specified position, the matching piece 42 and the driving structure 41 can be limited by the transverse blocking frame 52, so as to avoid the extension platform 30 from moving back and forth or shaking during the movement of goods and personnel, and after the transverse blocking frame 52 is pushed out, the top of the extension platform 30 can be supported and pressured by the pressure dividing assembly 53, so as to avoid sudden weight increase and damage to the driving structure 41, thereby making the entire retraction process more stable.

[0046] The mating member 42 and the driving structure 41 actually utilize the method of cooperating with a gear rack. When subjected to a back impact force or a forward swing force, the two are easily forced to move. Therefore, the lateral pushing member 51 of this embodiment includes a pushing member 511 arranged on the bottom of the cage frame 10, and one side of the pushing member 511 is connected to the external oil circuit. A pushing frame 512 is connected to the output end of the pushing member 511, and the end of the pushing frame 512 is connected to the transverse blocking frame 52, introducing the lateral pushing member 51 to interfere, and the hydraulically driven pushing member 511 directly interferes, thereby avoiding passive movement of the rack.

[0047] In order to avoid a relatively single force point of the pushing member 511 when being pushed, the pushing member 511 of this embodiment includes two sets of ejection rods, and the pushing frame 512 includes a long connecting handle 5121 connected to the lower end ejection rod, and the upper end of the long connecting handle 5121 is equipped with a short connecting handle 5122 through a connecting arm, and the short connecting handle 5122 is connected to the horizontal blocking frame 52, so that the pushing frame 512 driven by the pushing member 511 is divided into a multi-section handle-shaped structure, so that the tearing force can be segmented into different areas when the pushing frame 512 is subjected to force, avoiding direct disconnection at the connection position between the pushing frame 512 and the pushing member 511, and unloading force at multiple points.

[0048] In the process of the horizontal blocking frame 52 performing hard blocking on the rack, if it is only set as a single-strip structure, it is easy to deform and break due to the thin contact end. Therefore, the horizontal blocking frame 52 of this embodiment includes a plurality of embedded strips 521 connected to the short connecting handle 5122, and the width of the embedded strips 521 is equal to the spacing between the tooth tips on the rack. The top surfaces of all the embedded strips 521 are connected to an integrated board 522, and the integrated board 522 is attached to the outer side of the extension platform 30. The horizontal blocking frame 52 is set as a plurality of embedded strips 521, and all the embedded strips 521 are connected by the integrated board 522, which not only makes the embedded strips 521 become one, but also can provide a certain installation space for the pressure dividing assembly 53, thereby improving the horizontal blocking frame 52 and making better use of the space.

[0049] The purpose of setting the pressure-dividing component 53 is that when goods and personnel enter or leave the elevator, the load will change, which will have a greater impact on the driving structure 41, making it easy for the teeth to deform and cause discontinuous transmission during subsequent use, causing the platform to feel jerky. Therefore, the pressure-dividing component 53 of this embodiment includes a pneumatic push rod 531 arranged on the transverse barrier frame 52, and a pressure-dividing plate 532 is arranged on the top of the pneumatic push rod 531. The lower ends of both sides of the pressure-dividing plate 532 are connected to the transverse barrier frame 52 through springs 533. Through the set pressure-dividing component 53, support can be provided on both sides of the driving structure 41 after the driving structure 41 stops, thereby alleviating the pressure on the driving structure 41 when goods and personnel pass through, thereby avoiding deformation of this position after a large amount of load.

[0050] At the rear end of the movable frame 31, although there is a transverse blocking frame 52 in the middle, most accidents are caused by the platform retreating and causing goods or people to fall. Therefore, in this embodiment, a reverse thrust component 60 is arranged on the cage frame 10, and an inner groove is arranged on the bottom plate inside the cage frame 10. A receiving seat is arranged on the side of the movable frame 31 away from the building, and a reverse thrust component 60 is arranged in the inner groove. The reverse thrust component 60 includes an oblique push-pull member 61 arranged inside the inner groove, and the oblique push-pull member A push rod 62 is provided on the output end of 61, and the oblique push-pull member 61 is electrically connected to the pushing member 511. When the pushing member 511 is pushed out, the oblique push-pull member 61 is pushed out, so that the oblique push-pull member 61 can be pushed out after the movable frame 31 is pushed out, thereby holding the entire movable frame 31 from the rear end to prevent the extended platform 30 from sliding back. Combined with the horizontal blocking frame 52 in the middle, the extended platform 30 can be in a stable state during the entire construction process, so that the goods and personnel can be more stable in the process of going back and forth between the building and the elevator.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
