Description

Technical Field

[0001] The utility model relates to the field of construction platforms, in particular to a telescopic construction elevator platform. Background Technique

[0002] With the increasing maturity of the application technology of external elevators in construction, the application of external elevators without platform frames is becoming more and more widespread. When using a construction elevator, since there is a certain distance between the elevator and the building, it is necessary to use a flap door to erect a passage so that the staff can move from the elevator to the building.

[0003] The distance between the existing flap of the construction elevator and the floor surface is limited. When the construction elevator is far from the floor, the length of the flap cannot meet the requirements. If the flap is lengthened, its volume is large and its own weight is too heavy, which is inconvenient to operate. At the same time, the length of the flap is a fixed size. When the structure of the building is complex, the distances between the construction elevator and the floors are not equal. At this time, the flap of the construction elevator cannot meet the use requirements. The conventional method is to adopt an external scaffolding operation platform, which is time-consuming and laborious.

[0004] Therefore, a telescopic construction elevator platform is proposed now. Content of the Utility Model

[0005] In order to improve the problem that the distance between the existing flap of the construction elevator and the floor surface is limited. When the construction elevator is far from the floor, the length of the flap cannot meet the requirements. If the flap is lengthened, its volume is large and its own weight is too heavy, which is inconvenient to operate. At the same time, the length of the flap is a fixed size. When the structure of the building is complex, the distances between the construction elevator and the floors are not equal. At this time, the flap of the construction elevator cannot meet the use requirements, the utility model provides a telescopic construction elevator platform.

[0006] The utility model provides a telescopic construction elevator platform, adopting the following technical scheme:

[0007] A telescopic construction elevator platform includes an elevator car and a telescopic platform assembly installed at the entrance and exit of the elevator car. The telescopic platform assembly includes a first platform plate hinged to the inner bottom wall of the elevator car and a second platform plate installed above the first platform plate. Connecting shells are fixedly installed on both sides of the upper surface of the first platform plate. The second platform plate is slidably connected with the connecting shells. A driving assembly for driving the second platform plate to move is installed inside the connecting shells. A telescopic guardrail assembly is installed between the first platform plate and the second platform plate.

[0008] By adopting the above technical solution, the driving component drives the second platform plate to move telescopically, so that the front end of the second platform plate is placed on the floor slab surface. The length of the platform can be adjusted according to the distance from the building, thus realizing the rapid construction of the construction platform. Moreover, after use, the second platform plate retracts under the drive of the driving component, and then the first platform plate and the second platform plate stacked together are flipped into the elevator car to realize storage.

[0009] Optionally, a chute is provided on the inner side surface of the connection housing, and both sides of the second platform plate are located inside the chute.

[0010] By adopting the above technical solution, the second platform plate moves along the chute.

The output end of the motor is fixedly connected to the axis of the gear. Tooth groups are fixedly connected to the upper surfaces of both sides of the second platform plate, and the tooth groups are meshed with the gear.

[0012] By adopting the above technical solution, when the motor operates, it drives the gear to rotate, and the gear meshes with the teeth on the tooth group, thereby driving the second platform plate to move telescopically.

[0013] Optionally, limit blocks are fixedly connected to the upper surfaces of both sides of the second platform plate, and the limit blocks are located at the ends of the tooth groups.

[0014] By adopting the above technical solution, the setting of the limit blocks makes it difficult for the second platform plate to fall off from the inside of the chute when the gear drives the second platform plate to move.

[0015] Optionally, a plurality of balls are rotatably installed on the inner bottom wall of the chute, and the lower surface of the second platform plate contacts the tops of the balls.

[0016] By adopting the above technical solution, the setting of the balls reduces the friction between the second platform plate and the inner bottom wall of the chute, which is beneficial to the movement of the second platform plate.

[0017] Optionally, the telescopic guardrail assembly includes a first vertical rod installed on the first platform plate, a second vertical rod installed on the second platform plate, and a telescopic rod installed between the first vertical rod and the second vertical rod.

[0019] Optionally, mounting seats are fixedly installed on both the first platform plate and the second platform plate. The first vertical rod and the second vertical rod are both rotatably connected to the mounting seats, and a locking assembly is installed between the second vertical rod and the mounting seat.

[0020] By adopting the above technical solution, when the locking assembly releases the restriction on the second vertical rod, the guardrail composed of the first vertical rod, the second vertical rod, and the telescopic rod can be flipped onto the second platform plate.

[0021] Optionally, the locking assembly includes a threaded sleeve fixedly installed on the second vertical rod and a threaded rod threadedly connected to the mounting seat. One end of the threaded rod is threadedly connected to the threaded sleeve.

[0022] By adopting the above technical solution, by rotating the threaded rod, the connection and separation of the threaded rod and the threaded sleeve can be achieved, thereby realizing the locking and unlocking of the telescopic guardrail assembly by the locking assembly.

[0023] Optionally, reinforcing ribs are fixedly connected to the back surfaces of both the first platform plate and the second platform plate.

[0024] By adopting the above technical solution, the setting of the reinforcing ribs improves the bearing capacity of the first platform plate and the second platform plate.

[0025] In summary, the present utility model has the following beneficial effects:

[0026] 1. The present utility model drives the second platform plate to perform telescopic movement through the driving assembly, so as to be able to adjust the length of the construction platform composed of the second platform plate and the first platform plate according to the distance between the construction elevator and the floor, meet different construction requirements, and is convenient to operate;

[0027] 2. The present utility model protects the side of the construction platform composed of the first platform plate and the second platform plate through the telescopic guardrail assembly, improving safety. Moreover, when the locking assembly releases the restriction on the second vertical rod, the guardrail composed of the first vertical rod, the second vertical rod, and the telescopic rod can be flipped onto the second platform plate. At this time, the first platform plate and the second platform plate stacked together are then flipped into the interior of the elevator car to achieve storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings.

[0035] Please refer to Figures 1-4 , a retractable construction elevator platform, including an elevator car 1 and a retractable platform assembly installed at the entrance and exit of the elevator car 1. The retractable platform assembly includes a first platform plate 2 hinged to the inner bottom wall of the elevator car 1 and a second platform plate 3 installed above the first platform plate 2. Both the first platform plate 2 and the second platform plate 3 are diamond plates. Reinforcing ribs 17 are fixedly connected to the back surfaces of both the first platform plate 2 and the second platform plate 3. The setting of the reinforcing ribs 17 improves the bearing capacity of the first platform plate 2 and the second platform plate 3. Connection housings 4 are fixedly installed on both sides of the upper surface of the first platform plate 2. The second platform plate 3 is slidably connected to the connection housings 4. A slide groove 5 is formed on the inner side surface of the connection housing 4. Both sides of the second platform plate 3 are located inside the slide groove 5, and the second platform plate 3 moves along the slide groove 5.

[0036] Refer to Figure 1 and Figure 2 , a driving component for driving the movement of the second platform plate 3 is installed inside the connection housing 4. The driving component includes a gear 6 rotatably installed inside the connection housing 4 and a motor 7 installed on the outer side surface of the connection housing 4. The output end of the motor 7 is fixedly connected to the axis of the gear 6. Tooth groups 8 are fixedly connected to the upper surfaces of both sides of the second platform plate 3. The tooth groups 8 are meshed with the gear 6. When the motor 7 operates, it drives the gear 6 to rotate. The gear 6 meshes with the teeth on the tooth groups 8, thereby driving the second platform plate 3 to perform telescopic movement. Limit blocks 9 are fixedly connected to the upper surfaces of both sides of the second platform plate 3. The limit blocks 9 are located at the ends of the tooth groups 8. The setting of the limit blocks 9 makes it difficult for the second platform plate 3 to fall off from the inside of the slide groove 5 when the gear 6 drives the second platform plate 3 to move. A number of balls 10 are rotatably installed on the inner bottom wall of the slide groove 5. The lower surface of the second platform plate 3 contacts the tops of the balls 10. The setting of the balls 10 reduces the friction between the second platform plate 3 and the inner bottom wall of the slide groove 5, which is beneficial to the movement of the second platform plate 3.

[0037] Reference Figure 1 and Figure 3 , a telescopic guardrail assembly is installed between the first platform plate 2 and the second platform plate 3. The telescopic guardrail assembly includes a first vertical rod 11 installed on the first platform plate 2, a second vertical rod 12 installed on the second platform plate 3, and a telescopic rod 13 installed between the first vertical rod 11 and the second vertical rod 12. The telescopic guardrail assembly protects the side of the construction platform composed of the first platform plate 2 and the second platform plate 3, improving safety. Mounting seats 14 are fixedly installed on both the first platform plate 2 and the second platform plate 3. The first vertical rod 11 and the second vertical rod 12 are both rotatably connected to the mounting seats 14, and a locking assembly is installed between the second vertical rod 12 and the mounting seat 14. When the locking assembly releases the restriction on the second vertical rod 12, the guardrail composed of the first vertical rod 11, the second vertical rod 12, and the telescopic rod 13 can be flipped onto the second platform plate 3. At this time, the first platform plate 2 and the second platform plate 3 stacked together are then flipped into the interior of the elevator car 1 to achieve storage. The locking assembly includes a threaded sleeve 15 fixedly installed on the second vertical rod 12 and a threaded rod 16 threadedly connected to the mounting seat 14. One end of the threaded rod 16 is threadedly connected to the threaded sleeve 15. By rotating the threaded rod 16, the connection and separation of the threaded rod 16 and the threaded sleeve 15 can be achieved, thereby realizing the locking and unlocking of the telescopic guardrail assembly by the locking assembly.

[0038] The implementation principle of the present utility model is as follows: during use, the motor 7 drives the gear 6 to rotate. The gear 6 meshes with the teeth on the tooth group 8, thereby driving the second platform plate 3 to move telescopically, so that the front end of the second platform plate 3 rests on the floor slab surface. The length of the platform can be adjusted according to the distance from the building, ensuring that the contact between the platform plate and the floor slab is not less than 200 mm, thereby realizing the rapid construction of the construction platform. Moreover, after use, the second platform plate 3 retracts under the drive of the drive assembly, and at the same time, the locking assembly releases the restriction on the second vertical rod 12. The guardrail composed of the first vertical rod 11, the second vertical rod 12, and the telescopic rod 13 can be flipped onto the second platform plate 3. At this time, the first platform plate 2 and the second platform plate 3 stacked together are then flipped into the interior of the elevator car 1 to achieve storage.

[0039] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
