Description

Technical Field

[0001] The utility model relates to the technical field of shaft construction platforms, in particular to an adjustable diagonal bracing type shaft operation construction platform. Background Technique

[0002] The elevator shaft is the space for the movement of the car and the counterweight device or (and) the hydraulic cylinder plunger. This space is bounded by the bottom of the shaft pit, the shaft wall and the shaft top. When carrying out construction operations in the shaft, an operation platform is generally required for maintenance construction. Since the platform is triangular when the operation platform is erected, according to the principle of triangle stability, the side wall of the cylinder concrete is used without deformation, the lower end of the diagonal bracing channel steel is supported on the floor slab of the lower floor elevator door opening, and the upper end is inclined against the concrete wall opposite the door opening. When stressed, the lower end of the channel steel has a tendency to slide down. As long as the sliding of the lower end of the channel steel is prevented, the sinking of the operation platform can be stopped. Therefore, based on this principle, the operation platform is installed.

[0003] During the operation of the existing construction platform, it is easy to loosen and fall due to unstable placement, and it is not convenient to adjust. Therefore, we propose a set of adjustable diagonal bracing type shaft operation construction platforms. Content of the Utility Model

Specific implementation mode

[0026] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of this embodiment, rather than all the embodiments.

[0027] Embodiment 1

[0028] Referring to Figures 1-3 , an adjustable inclined strut type shaft operation construction platform includes:

[0029] Platform board 1;

[0030] Placement rack 2, installed at the bottom of platform board 1. Two symmetrically arranged vertical rods 3 are rotatably connected to the bottom of placement rack 2. An inclined strut 4 is installed on one side of vertical rod 3. Inclined strut 4 is rotatably connected to placement rack 2. Two connecting rods 5 are installed between the two vertical rods 3. Two fixed rods are installed between the two inclined struts 4;

[0031] Positioning assembly, installed on the two vertical rods 3;

[0032] Side support assembly, installed on the top of platform board 1.

[0033] In this embodiment, the positioning assembly includes two L-shaped clamping rods 9. Concave clamping plates 20 are fixedly installed on both vertical rods 3. Two positioning rods 7 are fixedly installed between the two concave clamping plates 20. Two side plates 8 are fixedly installed on one side of the two positioning rods 7. L-shaped clamping rod 9 is fixedly installed on side plate 8. The setting of positioning rod 7 can fixedly install L-shaped clamping rod 9 on the two vertical rods 3 through side plate 8, so that the setting of L-shaped clamping rod 9 can facilitate the fixed clamping of vertical rod 3 on the shaft side wall.

[0034] In this embodiment, the side support assembly includes two top plates 12. The two top plates 12 are movably installed on the platform plate 1. A rotating ring 11 is rotatably connected to the top of the platform plate 1. The rotating ring 11 is drivingly connected to the two top plates 12. Four symmetrically arranged mounting plates 13 are fixedly installed on the top of the rotating ring 11. A cylinder 14 is fixedly installed on one side of the mounting plate 13. The pistons of the two cylinders 14 on the same side are fixedly connected to the same top plate 12. The two top plates 12 on the rotating ring 11 move under the action of the cylinders 14 and the mounting plates 13, so as to push against the side wall of the shaft, and thus can stabilize the platform plate 1 in the left-right direction.

[0035] In this embodiment, a motor 15 is fixedly installed at the bottom of the platform plate 1. A rotating rod 16 is fixedly installed on the output shaft of the motor 15. The rotating rod 16 is drivingly connected to the rotating ring 11. A driving gear 17 is fixedly installed at the top end of the rotating rod 16. An internal gear ring 18 is fixedly installed inside the rotating ring 11. The driving gear 17 meshes with the internal gear ring 18. The output shaft of the motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the rotating ring 11 to rotate through the meshing of the driving gear 17 and the internal gear ring 18, and thus can drive the top plates 12 to change directions, so as to support and push in different directions.

[0036] In this embodiment, four symmetrically arranged lifting rings 10 are installed on the top of the platform plate 1. The same support rod 6 is fixedly installed between the inclined support rod 4 and the vertical rod 3. The arrangement of the support rod 6 can facilitate the support and stability of the vertical rod 3 and the inclined support rod 4, and thus can fix the fixing effect of the inclined support rod 4. At the same time, the arrangement of the lifting rings 10 can facilitate the hoisting of the device and facilitate handling.

[0037] In this embodiment, a plurality of adjustment holes 19 are formed in the vertical rod 3. A clamping sleeve is installed at the bottom end of the inclined support rod 4. The clamping sleeve cooperates with the adjustment holes 19. A bolt is threadedly connected to the adjustment holes 19. Through the arrangement of the bolt and the adjustment holes 19, the clamping sleeve can be clamped and positioned, and thus the angle of the inclined support rod 4 can be fixed.

[0038] Working principle: During operation, the positioning rod 7 is provided to fixedly install the L-shaped clamping rod 9 on the two vertical rods 3 through the side plate 8. The setting of the L-shaped clamping rod 9 facilitates the fixed clamping of the vertical rod 3 on the side wall of the shaft. The setting of the support rod 6 facilitates the support and stability of the vertical rod 3 and the diagonal support rod 4, thereby enhancing the fixing effect of the diagonal support rod 4. Meanwhile, the setting of the lifting ring 10 facilitates the hoisting of the device for easy handling. The adjusting hole 19 is internally threaded with a bolt. Through the setting of the bolt and the adjusting hole 19, the clamping sleeve can be clamped and positioned, and thus the angle of the diagonal support rod 4 can be fixed. The two top plates 12 on the swivel ring 11 move under the action of the cylinder 14 and the mounting plate 13, thereby pushing against the side wall of the shaft, and further stabilizing the platform plate 1 in the left-right direction. When it is necessary to adjust the support direction of the top plate 12, the motor 15 switch is activated. The output shaft of the motor 15 drives the rotating rod 16 to rotate. The rotating rod 16 drives the swivel ring 11 to rotate through the meshing of the driving gear 17 and the internal gear ring 18, and thus drives the top plate 12 to change its direction, so as to support and push in different directions.

[0039] Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 lies in that a toolbox is provided on the platform plate 1. The setting of the toolbox facilitates the placement of tool materials during shaft maintenance. All the structures in this application can be selected in terms of material and length according to the actual usage situation. The drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.

[0041] The above is only the preferred specific implementation manner of this embodiment, but the protection scope of this embodiment is not limited thereto. Any person skilled in the art within the technical scope disclosed by this embodiment, according to the technical solution of this embodiment and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of this embodiment.
