Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an elevator shaft construction platform. Background Technology

[0002] An elevator shaft is the shaft through which elevators are installed. The dimensions of the shaft are determined according to the type of elevator selected. Elevator rails and counterweight rails are installed on the shaft walls, and elevator doors are installed in the reserved door openings. The elevator machine room is located at the top of the shaft.

[0003] In building construction projects, the operating platform inside the elevator shaft often becomes a key and difficult point in building safety construction. The traditional method of using steel pipes to erect a support frame is not only troublesome to construct, but also causes the frame to sway, posing a safety hazard to workers during construction. Summary of the Invention

[0004] To address the problem of cumbersome construction platform setup for elevator shafts, this invention proposes an elevator shaft construction platform that can be quickly installed and fixed, facilitating lifting and moving within the elevator shaft and making it easy to use.

[0005] The technical solution adopted in this invention is to design an elevator shaft construction platform to provide temporary support for workers to carry out construction in the elevator shaft. The construction platform includes a platform and a support device for supporting the platform. The support device is a support positioning frame. The support positioning frame includes a vertical support frame located below the platform. The lower end of the vertical support frame is provided with a right-angle slot that can be locked onto the edge of the elevator door opening floor slab. On the other side of the platform opposite the support frame, a telescopic top support is provided for supporting the inner wall of the elevator shaft.

[0006] In some embodiments, the support frame and the platform are connected by connecting ribs, so that the connecting ribs, the platform, and the support frame form a triangular support structure.

[0007] In some embodiments, hanging rings are provided on the other two opposite sides of the platform.

[0008] In some embodiments, the support device is a telescopic support frame, which includes upper and lower deformable frames and a lifting rod connecting the two deformable frames. The deformable frame includes an upper support plate supported below the platform and two inclined top supports that support two opposite side walls of the elevator shaft. Each inclined top support is connected to the opposite sides of the upper support plate by two parallel rods through hinges, forming a parallel four-bar linkage. The two inclined top supports are rotatably connected to the ends of two support rods. The other ends of the two support rods are connected to a lower support plate through hinges. The lower support plate and the upper support plate are connected by a telescopic rod. The lower support plate of the upper deformable frame and the upper support plate of the lower deformable frame are connected by a lifting rod.

[0009] In some embodiments, a guide wheel support rod is fixedly connected to the support rod, one end of the guide wheel support rod is fixedly connected to the support rod and the other end is connected to a guide wheel facing the side wall of the elevator shaft, and the support rod and the guide wheel support rod form a "V" shape.

[0010] In some embodiments, the upper support plate of the lower deformation frame is provided with a control device for the telescopic rod and the lifting rod.

[0011] In some embodiments, both the telescopic rod and the lifting rod are hydraulic cylinders.

[0012] In some embodiments, the upper support plate of the upper deformation frame is fixedly connected to the platform.

[0013] In some embodiments, the deformable frame has two parallel four-bar linkages on each side, and the two parallel four-bar linkages are simultaneously connected to the inclined top support.

[0014] In some embodiments, the two ends of the inclined top support are respectively connected to two support rods, and the two support rods are respectively connected to the two ends of the guide wheel's shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The elevator shaft construction platform of the present invention can be hoisted into the elevator shaft by a crane or moved up and down in the elevator shaft. When it is necessary to move up and down in the elevator shaft, the platform can be moved up and down in the elevator shaft simply by retracting the telescopic top support into the insertion hole. When it moves to the corresponding position, the right-angle slot is locked into the floor slab at the elevator door opening, and the telescopic top support is extended. It is easy to install, has high safety, and ensures the safety of the operators.

[0017] 2. By designing the support device as a telescopic support frame, the construction platform can move automatically within the elevator shaft. Attached Figure Description

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.

[0027] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1:

[0029] like Figure 1 , 2 As shown in Figure 3, an elevator shaft construction platform is used to provide temporary support for workers to carry out construction in an elevator shaft 2. The construction platform includes a platform 1 and a support device for supporting the platform 1. The platform 1 is a plate that is slightly smaller than the elevator shaft 2. Workers can stand on the platform 1 to carry out construction in the elevator shaft 2.

[0030] The supporting device is a support positioning frame, which includes a vertical support frame 3 connected below the platform 1. The lower end of the vertical support frame 3 is provided with a right-angle slot 301 that can be locked onto the edge of the floor slab 4 of the elevator doorway 201, so that the lower end of the vertical support frame 3 is fixedly supported on the floor slab 4 at the elevator doorway 201. Opposite to the support frame, on the other side of the platform 1, a telescopic top support 5 is provided for supporting the inner wall of the elevator shaft 2. Thus, the telescopic top support 5 is opposite to the right-angle slot 301, so that the platform 1 is supported and fixed in the elevator shaft 2, and the telescopic top support 5 can extend and retract relative to the platform 1. For example, the telescopic top support 5 is a rod body, and an insertion hole 101 is provided on the side of the table surface 1. The telescopic top support 5 is inserted into the insertion hole 101. A first positioning hole 1011 is provided along the hole wall of the insertion hole 101. The telescopic top support 5 is distributed with second positioning holes 501 corresponding to the first positioning hole 1011. The positioning pin 6 is inserted into the first positioning hole and the second positioning hole 501 at the same time, so that the position of the first positioning hole 1011 relative to the second positioning hole 501 is fixed, and the extension length of the telescopic top support 5 relative to the table surface 1 is used to fix the table surface 1 relative to the slot.

[0031] The support frame is connected to the platform 1 by a connecting rib 7, thereby forming a triangular support structure with the connecting rib 7, the platform 1 and the support frame, making the structure more stable.

[0032] The platform 1 is provided with lifting rings 102 on its two opposite sides. During construction, a tower crane is used to lift the platform onto the lifting rings 102, thereby lifting the platform into the elevator shaft 2 or moving it up and down within the elevator shaft 2. When it is necessary to move the platform up and down within the elevator shaft 2, the telescopic top support 5 is retracted into the insertion hole 101, allowing the platform to move up and down within the elevator shaft 2. When it moves to the corresponding position, the right-angle slot 301 is engaged with the floor slab 4 at the elevator door opening 201, allowing the telescopic top support 5 to extend.

[0033] Example 2:

[0034] like Figure 1 , 2 As shown in Figure 3, unlike the above embodiments, the support device is a telescopic support frame, which includes two upper and lower deformable frames and a lifting rod 8 connected between the two deformable frames.

[0035] The deformable frame includes an upper support plate 9 supported below the platform 1 and two inclined top supports 10 that respectively support the two opposite side walls of the elevator shaft 2. Each inclined top support 10 is rotatably connected to the opposite sides of the upper support plate 9 via two parallel rods 11 and hinges 13. The inclined top supports 10, the upper support plate 9, and the two parallel rods 11 constitute a parallel four-bar linkage, ensuring that regardless of the deformation of the parallel four-bar linkage, the surface of the inclined top supports 10 always faces the inner wall of the elevator shaft 2. The upper support plate 9 of the upper deformable frame is fixedly connected to the platform 1.

[0036] The two inclined top supports 10 are rotatably connected to the ends of the two support rods 12 via hinges 13. The other ends of the two support rods 12 are connected to a lower support plate 14 via hinges 13. The lower support plate 14 is connected to the upper support plate 9 via a telescopic rod 15, thereby adjusting the distance between the lower support plate 14 and the upper support plate 9, thus changing the distance between the surface of the inclined top support 10 and the inner wall of the elevator shaft 2. The lower support plate 14 of the upper deformable frame is connected to the upper support plate 9 of the lower deformable frame via a lifting rod 8, thereby adjusting the distance between the upper and lower deformable frames. The telescopic rod 15 and the lifting rod 8 can both be hydraulic cylinders, or other controllable telescopic devices.

[0037] A guide wheel 17 and a support rod 1612 are fixedly connected to the support rod 12. One end of the guide wheel 17 and the support rod 1612 are fixedly connected to the support rod 12, and the other end is connected to the guide wheel 17 facing the side wall of the elevator shaft 2. The support rod 12 and the guide wheel 17 and the support rod 1612 form a "V" shape, so that when the lower support plate 14 moves up and down relative to the upper support plate 9, the guide wheel 17 and the support rod 12 swing synchronously. When the inclined top support head 10 approaches the inner wall of the elevator shaft 2, the guide wheel 17 moves away from the inner wall of the elevator shaft 2. Conversely, when the inclined top support head 10 moves away from the inner wall of the elevator shaft 2, the guide wheel 17 approaches the inner wall of the elevator shaft 2. When the inclined top support head 10 contacts the inner wall of the elevator shaft 2, the deformable frame is supported on the inner wall of the elevator shaft 2, thereby supporting the platform 1. When the guide wheel 17 contacts the inner wall of the elevator shaft 2, the lifting rod 8 allows the deformable frame to move up and down along the elevator shaft 2. The guide wheel 17 acts as a guide, preventing the edge of the platform 1 from rubbing against the inner wall of the elevator shaft 2. Figure 5 As shown, when the inclined top support 10 of the upper deformable frame is supported on the inner wall of the elevator shaft 2, and the guide wheel 17 of the lower deformable frame is in contact with the inner wall of the elevator shaft 2, the retraction of the lifting rod 8 can cause the lower deformable frame to rise. After moving to a certain height, as... Figure 6As shown, the inclined top support head 10 of the lower deformation frame is then supported on the inner wall of the elevator shaft 2, while the guide wheel 17 of the upper deformation frame contacts the inner wall of the elevator shaft 2. At this time, the lifting rod 8 extends upward, which allows the upper deformation frame and the platform 1 to rise, thus enabling the construction platform to move freely within the elevator shaft 2.

[0038] The deformable frame has two parallel four-bar linkages on each side, which are simultaneously connected to the inclined top support head 10 to improve the support strength. Two support rods 12 are connected to both ends of the inclined top support head 10, and these two support rods 12 are respectively connected to the two ends of the rotating shaft of the guide wheel 17.

[0039] The upper support plate 9 of the lower deformation frame is equipped with a control device 18 for the telescopic rod 15 and the lifting rod 8, such as a hydraulic pump for controlling the hydraulic cylinder, an electrical module, etc., so that the control device 18 can move with the platform.

[0040] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
