[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1-9 This application provides the following three preferred embodiments.

[0032] Example 1

[0033] An elevator shaft operating platform with varying floor levels includes two main beams and two connecting beams 3. Each main beam comprises two functional beams 1 and a custom beam 2. The two connecting beams 3 are horizontally bolted between the functional beams 1 of adjacent main beams. Both the functional beams 1 and the custom beams 2 are square steel tubular structures. Square assembly plates 4 are welded to one side of each functional beam 1 and both sides of each custom beam 2. The square assembly plates 4 on both sides of the custom beam 2 are fixedly connected to the square assembly plates 4 of the functional beams 1 by several bolts. Two plugs 25 are symmetrically arranged on both sides of the connecting beams 3. The two main beams are positioned opposite each other. Each functional beam 1 on one side is equipped with an installation socket 5. The two plugs 25 of the connecting beam 3 are respectively inserted into the installation sockets 5 on both sides of the functional beam 1 and fixed with bolts. Scaffold boards are horizontally laid on the upper end of the functional beam 1 and the square assembly plate 4. A safety component is movably inserted into one side of the functional beam 1. The safety component includes a safety steel beam 6 and a safety spring 21. A lifting connecting foot 15 is vertically and movably inserted into one side of each functional beam 1. The lifting connecting foot 15 movably penetrates and inserts into one side of the safety steel beam 6, limiting the movement of the safety steel beam 6. The overlapping component is horizontally and movably inserted into one side of the safety steel beam 6, and the overlapping... The connecting components include a lap joint 8, a safety steel beam 6 which is an I-shaped steel structure that can be inserted into the functional beam 1, a push-out plate 20 vertically welded to the side of the safety steel beam 6 near the customized beam 2, a support plate 19 vertically provided on the side of the functional beam 1 near the push-out plate 20, and a safety spring 21 horizontally provided between the support plate 19 and the push-out plate 20, an assembly hole vertically penetrating the side of the functional beam 1 near the mounting socket 5, a limit groove penetrating the horizontal connecting rib of the safety steel beam 6 at the position of the assembly hole, and a lifting connecting leg 15 vertically and movablely penetrating the assembly hole of the functional beam 1 and the safety steel beam 6. The assembly groove is set with steel cable lifting rings 18 and ejection springs 16 respectively at the upper and lower ends of the functional beam 1. The assembly groove 7 is located between the ejection springs 16 and the functional beam 1 and is fitted with ejection springs 16. The assembly groove 7 is opened on the side of the horizontal connecting bar away from the ejection plate 20 of the safety steel beam 6. The lap leg 8 is an I-shaped steel structure. The lap leg 8 and the connecting bar of the safety steel beam 6 are cross-shaped and interlocked. The vertical connecting bar of the lap leg 8 is placed in the assembly groove 7. The vertical connecting bar of the lap leg 8 is welded with sliding grooves 9 on both sides. The sliding grooves 9 are slidably fitted on both sides of the horizontal connecting bar of the safety steel beam 6.

[0034] When the device is in normal use, the existing building sling device and steel cable are connected to the steel cable rings 18 of the four lifting connecting feet 15 respectively. When working in the elevator shaft, it is directly hoisted to the corresponding height according to the construction floor. Then, the positioning screw 13 is loosened and the overlapping foot 8 is pushed out horizontally from the safety steel beam 6. When the fixing frame 12 moves to the maximum length of the first strip groove 11, the locking positioning screw 13 is tightened to fix the extension distance of the overlapping foot 8. Then, the lower end of the overlapping foot 8 is attached to the ground of the corresponding floor for stable support. After being stored, the device is convenient to be lifted and used with the floor.

[0035] During the hoisting process, the device is mainly supported by four lifting connecting feet 15 and steel cables. When one side of the steel cable breaks, two guide wheels 17 are symmetrically arranged on both sides of the limiting groove. One side of each guide wheel 17 contacts the lifting connecting foot 15. Under the sliding action of the guide wheel 17 and with the help of the push-out spring 16, the lifting connecting foot 15 quickly pops out of the functional beam 1. The safety spring 21 pushes one end of the safety steel beam 6 to quickly extend out of the functional beam 1 and abut against the building wall. Under the action of friction and the action of the other three steel cables, it is stuck to the wall, preventing the device from tilting excessively in the elevator shaft and causing a safety accident.

[0036] The width of the joint between the steel cable and the steel cable ring 18 of the lifting connecting foot 15 is smaller than the diameter of the lifting connecting foot 15, so as to prevent the lifting connecting foot 15 from being unable to detach from the functional beam 1 and the safety steel beam 6.

[0037] Example 2

[0038] Based on Embodiment 1, the extended use state of the overlapping leg 8 is fixed. A mounting plate 10 is horizontally welded to the upper end of the safety steel beam 6 on one side of the overlapping leg 8. Two first strip grooves 11 are symmetrically formed on both sides of the mounting plate 10. A second strip groove 24 is formed through the functional beam 1 on the side closest to the first strip groove 11. Two vertically symmetrical fixing brackets 12 are vertically formed on both sides of the upper end of the overlapping leg 8. The upper ends of the two fixing brackets 12 sequentially and movably pass through the first strip groove 11 and the second strip groove 24, respectively. The two sides of the fixing brackets 12 are vertically inserted via threads. The safety steel beam 6 is provided with positioning screws 13. The sliding grooves 9 of the overlapping leg 8 are provided with docking holes on one side of the positioning screws 13. The horizontal connecting ribs of the safety steel beam 6 are provided with eight positioning holes 14 symmetrically on both sides of the assembly groove 7. When the overlapping leg 8 is retracted and extended, the lower ends of the four positioning screws 13 pass through the docking holes of the sliding groove 9 and four of the positioning holes 14 respectively. The eight positioning holes 14 are divided into a group of four holes each, into a group of retracted holes and a group of extended holes, which are used to fix the overlapping leg 8 when it is extended and retracted. In addition, the length of the overlapping leg 8 of the safety steel beam 6 is greater than its extended length.

[0039] The length of the main beam is controlled according to the length of the customized beam 2, and the connecting beam 3 can be directly customized to the corresponding length for use.

[0040] Example 3

[0041] Based on Embodiment 2, the support strength of the main beam is enhanced by inserting a reinforcing component into one side of the main beam. The reinforcing component includes a reinforcing rod 23. A reinforcing connecting ring 22 is welded to the side of the functional beam 1 near the connecting beam 3. A reinforcing rod 23 is horizontally inserted between the two reinforcing connecting rings 22. A shock-absorbing rubber pad 26 is provided at the lower end of the side of the overlapping leg 8 extending out of the safety steel beam 6. The connecting beam 3 is flush with the two lifting connecting legs 15. When the load-bearing requirements of the device are large, a lifting connecting leg 15 can be added to the upper end of the connecting beam 3 for hoisting and load bearing. After the functional beam 1 is connected to the customized beam 2, a reinforcing rod 23 is horizontally inserted on one side to improve the load-bearing strength at the joint between the functional beam 1 and the customized beam 2. The two ends of the reinforcing rod 23 can be fixed and limited by nuts or prevented from falling off by pins.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
