Detailed Description

The utility model will be further described with reference to the accompanying drawings, without limiting the scope of the utility model to the following:

as shown in fig. 1 to 4, the present application provides a liftable gate-type scaffold, which at least comprises a frame body 1, a support plate 2 and a guard rail 3. The support plate 2 and the protective handrail 3 are both arranged on the frame body 1. In use, an operator stands on the support plate 2 for construction operations. Protection handrail 3 is located backup pad 2 all around, for operating personnel provides the protection, avoids constructor to drop from backup pad 2.

Preferably, the guard rail 3 includes at least a bracket 3a and a lifting rod 3 b. Support 3a sets up on support body 1, is provided with a plurality of connecting rod 4 on support 3a, and connecting rod 4 nests and sets up in lifter 3 b. The lifter bar 3b slides in the extending direction of the connecting bar 4. A plurality of first limiting holes 5 are formed in the lifting rod 3. The connecting rod 4 is provided with at least one second limiting hole 6. The first limiting hole 5 and the second limiting hole 6 are both provided with a limiting column 7 in a nested mode. The limiting column 7 can be a T-shaped bolt, and the T-shaped bolt can be provided with a nut to fix the T-shaped bolt and prevent the T-shaped bolt from falling off. When using, unscrew the nut and can take out T type nut, alright in order to reciprocate lifter 3b afterwards, make the whole height of liftable door type scaffold reduce, and then the liftable door type scaffold of being convenient for removes.

Preferably, a partition fence 8 is provided on the support plate 2 to partition the support plate 2 into a first area 2a and a second area 2 b. The first region 2a and the second region 2b are each provided with a slot 9. A first support plate 10 and a plurality of driving motors 11 are disposed below the first region 2a, and the driving motors 11 are connected to the first support plate 10. The driving motor 11 may be a push rod motor. The driving motor 11 is extended or shortened to realize the up and down movement of the first support plate 10. The first support plate 10 can enter the slot 9 of the first region 2a to seal the slot 9 when the first support plate is moved. When the support device is used, the first support plate 10 moves downwards to the lowest point, and then after an operator stands on the first support plate 10, the drive motor 11 drives the first support plate 10 to move upwards to the highest point, so that the operator can perform normal construction operation.

Preferably, a plurality of guide pillars 12 and second support plates 13 are disposed below the second region 2 b. The second support plate 13 is slidably connected to a plurality of guide uprights 12. The second support plate 13 is connected to the first support plate 10 via a connecting cord 14. The second support plate 13 may be provided with a guide hole, and the guide post 12 is nested in the guide hole, so that the second support plate 13 moves up and down along the extending direction of the guide post 12. Pulleys can be arranged on the frame body 1 to realize the steering of the connecting ropes. When the first support plate 10 is moved upward, the second support plate 13 may be pulled to move upward by the connection string 14. When the first leg plate 10 is moved downward through the connection 14, it is sufficient to pull the second support plate 13 upward. When the first support plate 10 moves upward, the second support plate 13 moves downward by its gravity. This application is when using, can stand on first support 10 and have first constructor, when first user need shift, the second constructor at first stands on second backup pad 13, and first backup pad 10 downstream just can drive the synchronous rebound of second backup pad 13 afterwards to can realize first constructor and second constructor's quick shift.

Preferably, both the first region 2a and the second region 2b have support regions 15 that are not hollow. The support areas 15 can be in abutting contact with each other.
