[0002] Elevator shaft support and positioning devices typically include frames, rails, and support components. By fixing the support structure within the shaft, they ensure that the operating machinery can move up and down along the shaft and maintain stability. The main function of these devices is to provide safety assurance for the installation of elevator guide rails, the car, and related equipment, preventing elevator malfunctions caused by construction errors.

[0003] However, these devices typically employ a fixed, ring-shaped structure. Adjusting the position of the operating machine requires repeated dismantling and rebuilding of the support frame, increasing the workload and labor intensity of construction workers and extending the construction period. Therefore, developing a support and positioning device for elevator shafts is particularly important. Utility Model Content

[0004] The purpose of this utility model is to provide a support and positioning device for elevator shafts, so as to solve the problem mentioned in the background art that requires repeated dismantling and rebuilding of the inner and outer frames.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support and positioning device for elevator shafts, comprising a vertical frame and an outer frame. The outer frame is fixedly connected to the outer wall of the vertical frame, and the vertical frame is fixed to the elevator shaft through the outer frame. A positioning plate is welded to the outer wall of the vertical frame, and a connecting structure is provided between the positioning plates on the same side. The connecting structure includes a fixing seat welded to the bottom end of the positioning plate. Two sets of connecting ribs are movably connected in the fixing seat. A connecting piece is fixedly connected to the top of the connecting rib. An inner groove is opened in the inner wall of the positioning plate, and a connecting piece fixedly connected to the connecting rib is embedded in the inner groove. A screw hole is machined on the bottom surface of the positioning plate. A fixing piece is welded to one side of the connecting rib, and a fixing bolt is fixedly connected between the fixing piece and the screw hole.

[0006] As a further technical solution of this utility model, the positioning plate is provided in eight sets, and the eight sets of positioning plates surround to form a circular processing space.

[0007] As a further technical solution of this utility model, the positioning plates on the same side are connected and merged by connecting pieces, and the screw holes are arranged in multiple sets at the bottom of the positioning plates.

[0008] As a further technical solution of this utility model, a connecting frame is fixedly connected to the outer wall of the upright frame, the positioning plate is fixedly connected to the outer frame through the connecting frame, and a rotatable inner frame is assembled inside the outer frame.

[0009] As a further technical solution of this utility model, four sets of detachable mounting parts are fixedly connected to the outer frame, and the outer frame and the inner frame form a concentric circle structure.

[0010] As a further technical solution of this utility model, a support rib is fixedly connected inside the inner frame, and a platform is located in the middle of the support rib, and an operating machine is supported on the platform.

[0011] As a further technical solution of this utility model, the outer wall of the inner frame is equipped with six sets of horizontal rollers, and the inner wall of the outer frame is machined with a horizontal track, and the horizontal rollers are embedded in the horizontal track and roll.

[0012] As a further technical solution of this utility model, inner wall tracks are provided above and below the horizontal track, and a set of steerable vertical rolling balls are installed at the top and bottom of the horizontal roller, and the vertical rolling balls form a rolling connection with the inner wall tracks.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the support and positioning device for elevator shafts not only achieves better support and flexible positioning construction without dismantling and rebuilding the inner and outer frames, but also achieves structural stability and smoothness in narrow spaces, and provides multi-directional support, ensuring construction safety and reducing the risk of accidents.

[0014] (1) By setting up positioning plates, fixed seats, fixed pieces, fixed bolts, screw holes, connecting pieces, inner grooves, and connecting ribs, when the machine is working on the platform and needs to adjust its position up and down along the elevator shaft, the fixed bolts can be removed. By retracting the connecting ribs at the bottom of the positioning plate, the connecting pieces can be retracted into the positioning plate, so that the corresponding gaps are opened between the positioning plates on the same side. At the same time, the added parts are removed, so that the corresponding gaps are opened in the outer frame. At this time, the inner frame is rotated, the machine is turned, and the upper and lower operations can be carried out through the inner frame without dismantling and rebuilding the inner and outer frames, so as to achieve better support and flexible positioning construction.

[0015] (2) By setting up horizontal tracks, horizontal rollers, inner wall tracks, and vertical rolling balls, the entire inner frame can rotate inside the outer frame, driving the operating machine to turn. When the inner frame rotates, the horizontal rollers roll in the horizontal tracks on the inner wall of the outer frame, while the two sets of vertical rolling balls above and below the horizontal rollers roll in the inner wall tracks, thereby realizing a double rolling structure in the horizontal and vertical directions, ensuring the smoothness of the inner frame rotation, making the operation of the machine more stable, and the structure is stable and smooth in a narrow space.

[0016] (3) By setting up a positioning plate, outer frame, connecting frame, inner frame, support ribs and platform, the positioning plate and outer frame inside the device are connected by the connecting frame, and the platform is formed by the support ribs inside the inner frame. Multiple sets of connecting ribs can form support from multiple directions, reduce the instability caused by construction vibration, ensure construction safety and reduce the risk of accidents.

The connecting piece 8, which is fixedly connected to the connecting rib 10, is embedded in the inner groove 9. A screw hole 7 is machined on the bottom surface of the positioning plate 3. A fixing piece 5 is welded to one side of the connecting rib 10. A fixing bolt 6 is fixedly connected between the fixing piece 5 and the screw hole 7. A total of eight sets of positioning plates 3 are provided. The eight sets of positioning plates 3 surround to form a circular processing space. The positioning plates 3 on the same side are connected and merged through the connecting piece 8. Multiple sets of screw holes 7 are arrayed at the bottom end of the positioning plate 3.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when the operating machine 17 is working on the platform 16 and needs to adjust its position up and down along the elevator shaft, the fixing bolt 6 can be removed. By retracting the connecting rib 10 at the bottom of the positioning plate 3, the connecting piece 8 can be retracted into the positioning plate 3, so that the corresponding gaps are opened between the positioning plates 3 on the same side. At the same time, the addition part 13 is removed, so that the corresponding gaps are opened in the outer frame 12. At this time, the inner frame 14 is rotated, the operating machine 17 turns, and the inner frame 14 can be used for up and down operations without dismantling and rebuilding the inner frame 14 and the outer frame 12.

[0025] A connecting frame 11 is fixedly connected to the outer wall of the upright frame 2. The positioning plate 3 is fixedly connected to the outer frame 12 through the connecting frame 11.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the entire inner frame 14 can rotate inside the outer frame 12, driving the operating machine 17 to turn. When the inner frame 14 rotates, the horizontal roller 19 rolls in the horizontal track 18 on the inner wall of the outer frame 12.

A platform 16 is formed inside the inner frame 14 via supporting ribs 15. Multiple sets of connecting ribs provide support from multiple directions. The entire inner frame 14 can rotate inside the outer frame 12, driving the operating machine 17 to turn. When the inner frame 14 rotates, the horizontal rollers 19 roll in the horizontal tracks 18 on the inner wall of the outer frame 12. Simultaneously, the two sets of vertical rolling balls 21 on the upper and lower parts of the horizontal rollers 19 roll in the tracks 20 on the inner wall, thus achieving a double rolling structure in both the horizontal and vertical directions, ensuring the smooth rotation of the inner frame 14. The operating machine 17... 7. Construction is more stable. When the operating machine 17 is working on the platform 16 and needs to adjust its position up and down along the elevator shaft, the fixing bolt 6 can be removed. By retracting the connecting rib 10 at the bottom of the positioning plate 3, the connecting piece 8 can be retracted into the positioning plate 3, so that the corresponding gaps are opened between the positioning plates 3 on the same side. At the same time, the addition part 13 is removed, so that the corresponding position of the outer frame 12 is opened. At this time, the inner frame 14 is rotated, the operating machine 17 turns, and the up and down operation can be carried out through the inner frame 14. It is not necessary to dismantle and rebuild the inner frame 14 and the outer frame 12, so as to achieve better support and flexible positioning construction.
