[0001] The utility model belongs to the technical field of support devices, and particularly relates to an elevator shaft support device for elevator installation. Background Art

[0002] When installing an elevator, a support device is required to support the work of installers. The existing support devices are not suitable for extending into the elevator shaft, and the support devices are movably supported on the inner wall of the elevator shaft, with poor reliability. When installing rails and other parts in the elevator shaft, it is not convenient for installers to turn around for operation, and the protection is poor during climbing and moving. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to extend support for the operation of installers into the elevator shaft, facilitate the turn of installers, and improve the support reliability and protection.

[0004] To solve the above technical problems, the technical scheme adopted by the utility model is as follows: An elevator shaft support device for elevator installation, including symmetrically distributed connecting plates, sleeves penetrating through the opposite inner side walls of the connecting plates, and a support mechanism fixedly connected to one side of the symmetric connecting plates. A support frame with a stable structure is formed between the connecting plates and the sleeves. The support mechanism is connected and extended into the elevator shaft through the symmetric connecting plates for carrying personnel to work.

[0005] Further, the support mechanism includes support diagonal rods and a bearing assembly. One end of each support diagonal rod is fixedly connected to the side wall of the connecting plate. The support diagonal rods are symmetrically arranged up and down. The ends of the symmetric support diagonal rods away from the connecting plate are close to each other and fixedly connected. The bearing assembly is rotatably connected between the symmetric connecting plates in the horizontal direction.

[0006] Further, the bearing assembly includes a bearing rod, a fixed block, and a rotating plate. The bearing rod is fixedly connected between the symmetric support diagonal rods in the horizontal direction. The bearing rod is located on the side of the support diagonal rods away from the connecting plate. The fixed block is fixedly connected to the middle of the outer side wall of the bearing rod. The rotating plate is rotatably connected to the upper part of the fixed block.

[0007] Further, a cross bar is fixedly connected between the symmetric support diagonal rods in the horizontal direction. The cross bars are arranged at uniform intervals. An activity opening is left on the side of the symmetric support diagonal rods in the horizontal direction away from the cross bar.

[0008] Further, columns are arranged on the upper part of the rotating plate. The columns are symmetrically arranged. A blocking rod is connected between the symmetric columns. The blocking rods are arranged at uniform intervals in the up and down direction. The blocking rod is in a semi-circular arc shape.

[0009] Further, internal threads are provided at both ends of the sleeve for threaded connection with studs. The symmetric studs are connected with reverse threads. One end of each stud away from the sleeve is rotatably connected with a positioning plate. The positioning plate is arranged in an L shape, and a positioning hole is formed on one side of the positioning plate parallel to the stud.

[0010] After adopting the above structure, the beneficial effects of the present utility model are as follows: For the support of installers during the installation of an elevator in an elevator shaft, a stable support framework is formed by the sleeve and the connecting plate, enhancing the connection stability of the support mechanism. The support mechanism extends into the elevator shaft. By using the studs threadedly connected to both ends of the sleeve, the studs are pushed to move outwards in opposite directions. The positioning plates are bolted to the elevator wellhead, enabling fixation on the outer sides of elevator wellheads with different widths. When the installer is working, they climb onto the bearing assembly through the movable opening and turn around to work on the bearing assembly, which is applicable to the installation of guide rails and components on different inner walls of the elevator shaft.

[0016] As Figures 1-3 shown, a support device for an elevator wellhead during elevator installation includes symmetrically distributed connecting plates 1, sleeves 2 penetrating the opposite inner side walls of the connecting plates 1, and a support mechanism 3 fixedly connected to one side of the symmetric connecting plates 1. A stable support framework is formed by connecting the connecting plates 1 and the sleeves 2. The support mechanism 3 is fixedly connected through the symmetric connecting plates 1 and extends into the elevator shaft for carrying personnel to work.

[0017] As Figure 1 andFigure 2 As shown, in order to support the installation personnel's operation inside the elevator shaft, the support mechanism 3 includes support diagonal rods 4 and a load-bearing assembly 5. One end of each support diagonal rod 4 is fixedly connected to the side wall of the connecting plate 1. The support diagonal rods 4 are symmetrically arranged up and down. The ends of the support diagonal rods 4 that are symmetrically arranged up and down and are far from the connecting plate 1 approach each other and are fixedly connected. The load-bearing assembly 5 is rotatably connected between the horizontally symmetric connecting plates 1. A cross bar 9 is fixedly connected between the horizontally symmetric support diagonal rods 4. The cross bars 9 are arranged at uniform intervals. There is an activity opening 10 on the side of the horizontally symmetric support diagonal rods 4 that is far from the cross bar 9. The support diagonal rods 4 that are symmetrically arranged up and down and the connecting plate 1 form a triangular stable structure. The cross bar 9 between the horizontally symmetric support diagonal rods 4 is used to bear the movement of the installation personnel. When the installation personnel enter the elevator shaft through the device, they step on the cross bar 9 and climb onto the load-bearing assembly 5 through the activity opening 10.

[0018] In order to facilitate the installation personnel to turn around inside the elevator shaft and install parts on different side walls of the elevator shaft, the load-bearing assembly 5 includes a load-bearing rod 6, a fixed block 7, and a rotating plate 8. The load-bearing rod 6 is fixedly connected between the horizontally symmetric support diagonal rods 4. The load-bearing rod 6 is located on the side of the support diagonal rods 4 that is far from the connecting plate 1. The fixed block 7 is fixedly connected to the middle of the outer side wall of the load-bearing rod 6. The rotating plate 8 is rotatably connected to the upper part of the fixed block 7. There are upright columns 11 on the upper part of the rotating plate 8. The upright columns 11 are symmetrically arranged. A blocking rod 12 is connected between the symmetric upright columns 11. The blocking rods 12 are arranged at uniform intervals in the up and down direction. The blocking rods 12 are in a semi-circular arc shape. The installation personnel stand on the rotating plate 8 through the activity opening 10. The load-bearing rod 6 and the fixed block 7 support the rotating plate 8 and are connected between the horizontally symmetric support diagonal rods 4. The multiple blocking rods 12 are used for the protection of one side of the installation personnel. When the rotating plate 8 rotates and adjusts, the body of the installation personnel can rotate synchronously with the multiple blocking rods 12.

[0019] As Figure 1 shown, in order to install the device outside the elevator shaft opening and be applicable to the installation of elevator shaft openings with different widths, threaded columns 13 are internally threaded at both ends of the sleeve 2. The symmetric threaded columns 13 are connected with reverse threads. One end of the threaded column 13 that is far from the sleeve 2 is rotatably connected to a positioning plate 14. The positioning plate 14 is in an L shape. A positioning hole 15 is opened on the side of the positioning plate 14 that is parallel to the threaded column 13. When the positioning plate 14 fits against the outer wall of the elevator shaft opening, rotate the sleeve 2 to make the threaded columns 13 at both ends move and extend towards each other, broadening the lateral support distance of the sleeve 2, and then bolt it to the outer wall of the elevator shaft through the positioning hole 15 to achieve the fixed connection of the device.

[0020] During specific use, in the initial state, the studs 13 at both ends of the sleeve 2 are in a state of being retracted inside the sleeve 2. The operator extends the device into the elevator shaft through the elevator shaft opening, making the positioning plate 14 fit against the outer wall of the elevator shaft opening parallel to one side wall of the sleeve 2. Then, the sleeve 2 is rotated to make the studs 13 at both ends move towards each other and extend, widening the lateral support distance of the sleeve 2. Next, bolts are inserted into the positioning holes 15 to connect the device to the outer wall of the elevator shaft, realizing the fixed connection of the device.

[0021] When installers enter the elevator shaft, they step on the lower crossbar 9 between the symmetrically arranged connecting plates 1 and climb onto the rotating plate 8 through the movable opening 10. The upper crossbar 9 is used for installers to hold with their hands to maintain body balance. When the installers stand on the rotating plate 8, multiple stop bars 12 are used for the protection of one side of the installers. By rotating the rotating plate 8, the bodies of the installers and the multiple stop bars 12 rotate synchronously, which is used for the installation of parts on different side walls inside the elevator shaft.
