The technical features not disclosed in this embodiment are the same as those in specific embodiment one.

[0027] In this embodiment, the front and rear sides of the supporting chassis 2 can be directly supported and erected on the side walls of the elevator shaft, and will not slide or collapse. The shape of the supporting chassis 2 can be designed according to the weight and size of the upper concrete placer body 1 to ensure that the supporting chassis 2 can stably support the concrete placer body 1 in the elevator shaft. The shape of the supporting chassis 2 can be a triangular or quadrilateral framework to facilitate the erection on both sides, and diagonal bracing beams are arranged inside it to enhance the overall stability of the supporting chassis 2.

[0028] Specific Embodiment Three: Combining Figures 1 to 3 To illustrate this embodiment, the supporting chassis 2 described in this embodiment is arranged inside the elevator shaft door opening. The technical features not disclosed in this embodiment are the same as those in Specific Embodiment Two.

[0029] In this embodiment, the elevator shaft door opening is utilized for the erection of the supporting chassis 2. The supporting chassis 2 enters from the elevator shaft door opening. The front end of the supporting chassis 2 is erected on the side wall opposite to the elevator shaft door opening, and the rear end of the supporting chassis 2 is erected on the side wall below the elevator shaft door opening. To enhance the stability of the supporting chassis 2, a plurality of diagonal bracing beams are arranged inside the supporting chassis 2, and the rear end of one group of diagonal bracing beams can be supported on the ground outside the elevator shaft door opening.

[0030] Specific Embodiment Four: Combining Figure 2 To illustrate this embodiment, a fixed seat 5 is fixedly connected to one side of the supporting chassis 2 described in this embodiment, and one side of the horizontal base 3 is hinged to the fixed seat 5 through a pin shaft 6. The technical features not disclosed in this embodiment are the same as those in Specific Embodiment One.

[0031] Such a design is to achieve the rotational connection between one side of the horizontal base 3 and the supporting chassis 2.

[0032] Specific Embodiment Five: Combining Figure 2 To illustrate this embodiment, the leveling mechanism described in this embodiment includes a leveling hydraulic cylinder 7, a cylinder block seat 8, and an adjusting seat 9. The cylinder block seat 8 is fixedly connected to the other side of the supporting chassis 2, and the adjusting seat 9 is fixedly connected to the lower end surface of the other side of the horizontal base 3. One end of the leveling hydraulic cylinder 7 is hinged to the cylinder block seat 8, and the other end of the leveling hydraulic cylinder 7 is hinged to the adjusting seat 9. The technical features not disclosed in this embodiment are the same as those in Specific Embodiment One.

[0033] Such a design realizes the horizontal adjustment of the horizontal base 3 through the telescopic movement of the leveling hydraulic cylinder 7.

[0034] Specific Embodiment Six: Combining Figures 1 to 5To describe this embodiment, the suspended working platform assembly in this embodiment includes a working platform 10, a slewing motor 11, a reel 12, two rollers 13 and two cables 14. The reel 12 is arranged at the upper end of the horizontal base 3. The output shaft of the slewing motor 11 is connected to one end of the reel 12. The two rollers 13 are fixedly connected in parallel on the outer side of the reel 12. One end of each cable 14 is fixedly connected to the outer circumferential side wall of one roller 13 respectively. The other ends of the two cables 14 are symmetrically hung on the working platform 10 respectively. The working platform 10 is arranged below the supporting chassis 2. The technical features not disclosed in this embodiment are the same as those in the first specific embodiment. The reel 12 is horizontally arranged at the upper end of the horizontal base 3 through two supports 21, and the reel 12 is rotatably connected to the supports 21 through bearings.

[0035] In this embodiment, the working platform 10 is arranged below the supporting chassis 2 and is suspended by two cables 14. When the slewing motor 11 rotates forward, the reel 12 drives the two rollers 13 to rotate forward, and the cables 14 are wound around the rollers 13, and the working platform 10 rises; when the slewing motor 11 rotates reversely, the reel 12 drives the two rollers 13 to rotate reversely, and the cables 14 are released from the rollers 13, and the working platform 10 descends. In this way, the height of the working platform 10 can be adjusted according to actual needs to meet the working requirements.

[0036] Specific embodiment seven: Combine Figures 1 to 5 To describe this embodiment, one steel wire rope 15 is symmetrically arranged on each side of the working platform 10 in this embodiment. The middle part of the steel wire rope 15 bypasses the lower end of the working platform 10, and the end parts of the steel wire rope 15 are respectively connected to the other ends of the cables 14 correspondingly. The technical features not disclosed in this embodiment are the same as those in the sixth specific embodiment.

[0037] With such a design, the other end of the cable 14 realizes the suspension of the working platform 10 through the steel wire rope 15. By using the steel wire rope 15 to bypass the lower end of the working platform 10, the entire working platform 10 is supported, thereby enhancing the stability of the working platform 10.

[0038] Specific embodiment eight: Combine Figures 1 to 4 To describe this embodiment, a chain block 16 is arranged between the other end of one cable 14 and the end part of the corresponding steel wire rope 15 in this embodiment. The connecting end of the chain block 16 is connected to the other end of the cable 14. The driving end of the chain block 16 is arranged inside the working platform 10, and the executing end of the chain block 16 is connected to the end part of the steel wire rope 15. The technical features not disclosed in this embodiment are the same as those in the seventh specific embodiment.

[0039] In this embodiment, the reel 12 is driven to rotate by the slewing motor 11. After long-term use, the lengths of the two cables 14 will be different, resulting in the inclination of the working platform 10. Therefore, a chain block 16 is provided. When the working platform 10 is inclined, the operators in the working platform 10 can adjust by pulling the two driving ends of the chain block 16 respectively, so as to lift and lower one side of the working platform 10 and adjust the working platform 10 to a horizontal state, which is convenient for operation and can prevent the working platform 10 from tilting and overturning.

[0040] Specific Embodiment Nine: In combination with Figures 1 to 5 This embodiment is described. A plurality of columns 17 are fixedly connected to the upper end surface of the working platform 10 in a circumferentially evenly distributed manner, and a guardrail 18 is provided between every two adjacent columns 17. The technical features not disclosed in this embodiment are the same as those in Specific Embodiment Seven.

[0041] In this embodiment, the arrangement of the columns 17 can enhance the overall strength of the working platform 10, and the arrangement of the guardrail 18 can prevent the operators from falling and ensure the operation safety.

[0042] Specific Embodiment Ten: In combination with Figures 1 to 5 This embodiment is described. A plurality of guide sleeves 19 are sleeved on the outer side of the steel wire rope 15, and the guide sleeves 19 are fixedly connected to the outer end surfaces of the working platform 10 and the columns 17 respectively. The technical features not disclosed in this embodiment are the same as those in Specific Embodiment Nine.

[0043] In this embodiment, the arrangement of the guide sleeves 19 can limit the position of the steel wire rope 15, prevent the steel wire rope 15 from shifting, avoid the inclination of the working platform 10, and ensure the stability of the working platform 10.
