Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete tower hoisting technology, and in particular to a safety protection device for construction personnel on a temporary construction platform for concrete towers. Background Technology
[0002] Currently, to ensure construction quality, the hoisting operation of concrete tower sections involves assembling the concrete tower sections on the ground and applying structural adhesive to the top of the concrete tower sections inside the tower. During construction inside the concrete tower, workers stand on a temporary construction platform, secured to the embedded parts of the concrete tower section by eight lifting points. The workers' safety belts lack a fixed anchor point, compromising safety. Furthermore, when the construction platform is lifted, workers must descend onto the concrete tower ladder, increasing the risk of falls. Therefore, a safety device for workers operating temporary construction platforms for concrete towers is needed. Utility Model Content
[0003] This utility model aims to address the shortcomings of existing technologies by providing a safety protection device for construction workers on a temporary construction platform for concrete towers.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a safety protection device for construction workers on a temporary construction platform for a concrete tower. Construction workers wear double-hook safety belts. A movable construction platform is installed inside the concrete tower, comprising: a horizontal safety rope and a vertical safety rope. Diagonal bolts are fixedly installed on the inner side of the concrete tower, and seamless steel pipes are screwed onto the diagonal bolts. A cross-shaped opening is provided on the seamless steel pipe. The horizontal safety rope is located above the construction platform, and both ends of the horizontal safety rope can pass through the cross-shaped opening and be fixedly connected to the seamless steel pipe. Several mixed-tower section lifting devices are fixedly installed at the top of the concrete tower. The upper end of the vertical safety rope can be fixed to the mixed-tower section lifting device. The hooks of the double-hook safety belt can be hooked onto either the horizontal or vertical safety rope.
[0005] Furthermore, during construction, the construction platform is fixed to the inside of the concrete tower using platform fixing components.
[0006] Furthermore, the construction platform is provided with several hanging points. When the construction platform moves up and down, each hanging point is fixedly connected to a sling, and the other end of the sling is hung on the crane hook.
[0007] Furthermore, a pair of diagonal bolts are respectively disposed at both ends of the inner radial side of the concrete tower, and multiple pairs of diagonal bolts are evenly distributed vertically along the inner side of the concrete tower.
[0008] Furthermore, several of the aforementioned concrete tower section lifting devices are evenly distributed circumferentially on the top of the concrete tower.
[0009] Furthermore, several of the hanging points are evenly distributed circumferentially along the edge of the construction platform.
[0010] The beneficial effects of this utility model are as follows: By setting horizontal and vertical safety ropes, this utility model can ensure that the double hooks of the safety belts of construction workers on the construction platform are fixed, which solves the problem of fall accidents caused by incorrect placement of the double hooks of the safety belts when concrete tower construction workers are working on temporary construction platforms. When the temporary construction platform is lifted, construction workers do not need to risk climbing onto the ladder, thus improving the safety of construction workers during the fixing and lifting of the temporary construction platform.

[0019] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0021] like Figures 1-6As shown, a safety device for construction workers on a temporary construction platform for a concrete tower is provided. Workers 1 wear double-hook safety belts 2. A movable construction platform 4 is installed inside the concrete tower 3, including a horizontal safety rope 5 and a vertical safety rope 6. Diagonal bolts 7 are fixedly installed inside the concrete tower 3, and seamless steel pipes 8 are screwed onto the diagonal bolts 7. Cross-shaped openings 9 are provided on the seamless steel pipes 8. The horizontal safety rope 5 is located above the construction platform 4, and both ends of the horizontal safety rope 5 can pass through the cross-shaped openings 9 and be fixedly connected to the seamless steel pipes 8. Several mixed-tower section lifting devices 10 are fixedly installed at the top of the concrete tower 3. The upper end of the vertical safety rope 6 can be fixed to the mixed-tower section lifting device 10. The hooks of the double-hook safety belt 2 can be hooked onto either the horizontal safety rope 5 or the vertical safety rope 6.
[0022] Specifically, during construction, the construction platform 4 is fixed inside the concrete tower 3, and the two ends of the horizontal safety rope 5 are fixed to the diagonal bolts 7 of the concrete tower through seamless steel pipes 8. The construction worker 1 hangs the double hooks of the double hook safety belt 2 on the horizontal safety rope 5. When the construction platform is lifted and moved, the vertical safety rope 6 is fixed on the concrete tower section lifting device 10, and the construction worker 1 hangs the double hooks of the double hook safety belt 2 on the vertical safety rope 6.
[0023] During construction, the construction platform 4 is fixed to the inside of the concrete tower 3 by platform fixing components 11.
[0024] The construction platform 4 is provided with several hanging points 12. When the construction platform 4 moves up and down, each hanging point 12 is fixedly connected to a sling 13, and the other end of the sling 13 is hung on the crane hook 14.
[0025] A pair of diagonal bolts 7 are respectively disposed at both ends of the inner radial side of the concrete tower 3, and multiple pairs of diagonal bolts 7 are evenly distributed vertically along the inner side of the concrete tower 3.
[0026] Several of the aforementioned concrete tower section lifting devices 10 are evenly distributed circumferentially on the top of the concrete tower cylinder 3.
[0027] Several hanging points are evenly distributed along the circumference at the edge of the construction platform 4.
[0028] The method of use and working principle of this utility model is as follows: When working on the fixed construction platform 4, a horizontal safety rope 5 is fixed at the diagonal bolt 7 of the mixed tower section above the construction platform 4. The construction worker 1 hangs the double hooks of the double hook safety belt 2 on the horizontal safety rope 5. This can not only ensure the smoothness of the operation, but also protect the personnel in the event of a fall from the construction platform 4, preventing the personnel from falling.
[0029] When moving the construction platform 4, install a vertical safety rope 6 on the lifting device 10 of the mixed tower section, hook the double hooks of the double hook safety belt 2 of the construction worker 1 onto the vertical safety rope 6, remove the horizontal safety rope 5, and then hook the four hanging points 12 of the construction platform 4 onto the crane hook 14 through the sling 13. Remove the platform fixing parts 11 of the construction platform 4, and the construction worker 1 moves up to the next working plane with the construction platform 4. After the construction platform 4 is fixed, fix the horizontal safety rope 5, and then remove the double hooks and hook them onto the horizontal safety rope 5. The crane slowly lowers the crane hook 14. When the construction platform 4 is completely fixed, remove the sling 13 of the construction platform 4, and the construction worker 1 continues to work.
[0030] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
