specific Embodiment approach 1

[0034] Specific implementation mode one: as Figure 1-Figure 16 As shown, this embodiment describes a safety protection device for workers in road and bridge construction, including protection device I1, protection device II2, protection device III3, and protection device IV4; the protection device I1 includes a housing 1-1, a sliding bucket 1 -2, fixed cylinder 1-3, inner shell 1-4, telescopic rod 1-5, upper baffle 1-6, lower baffle 1-7, screw rod 1-8, threaded cylinder 1-9, rectangular rod 1- 10. Motor 1-11, bracket 1-12, circular plate I 1-13, circular plate II 1-15 and multiple springs 1-14; the housing 1-1 is fixedly connected to the upper end of the sliding barrel 1-2; the The motor 1-11 is fixedly connected to the inner top of the casing 1-1 through the bracket 1-12, and the output shaft of the motor 1-11 is fixedly connected with fan blades; The inner top; the fixed cylinder 1-3 is slidingly matched with the sliding barrel 1-2, and the inner middle position of the fix...

specific Embodiment approach 2

[0039] Specific implementation mode two: as Figure 8 As shown, this embodiment is a further description of specific embodiment 1. The diameters of the semicircle I3-1 and semicircle II4-1 are equal, and the semicircle I3-1 and semicircle II4-1 The diameters are greater than the distance between two adjacent vertical bars 7 on the scaffold. The combination of the semicircle I3-1 and the semicircle II4-1 can prevent workers from falling out of the scaffold from the gap between the two vertical bars 7.

specific Embodiment approach 3

[0040] Specific implementation mode three: as Figure 4 As shown, this embodiment is a further description of Embodiment 1. The connecting end of the sliding bar 2-3 and the safety vest 2-1 is fixedly connected with a rubber pad, and the rubber pad is fixedly connected with the safety vest 2-1.

Abstract

The invention discloses a worker safety protection device and method for road and bridge construction, and belongs to the field of protection tools for road and bridge construction workers. Meanwhile,the device is fixed on the body of a worker through the protection device II, so that the portability of the device can be ensured; the diameter of a circular ring formed after the protection deviceIII and the protection device IV are combined is larger than the distance between the two scaffold vertical rod supports, and the situation that a worker is accidentally impacted or falls off from thehigh altitude due to the unstable center of the worker can be effectively avoided. And finally, the device is further provided with a supporting device, when the worker works vertically, the weightsof the protection device I, the protection device II, the protection device III and the protection device IV can be supported on the supporting device, the pressure borne by the worker is reduced, andthen the fatigue of the worker due to load bearing is reduced. When a worker squats to work, a sitting plate can be provided for the worker, physical exhaustion of the worker is reduced, and leg paralysis of the worker is prevented.

Description

technical field [0001] The invention relates to a safety protection device for workers in road and bridge construction and a protection method, belonging to the field of protective equipment for road and bridge construction workers. Background technique [0002] In the process of bridge construction, workers need to reinforce the steel bars during the construction of the bridge piers, and the height of the bridge piers is constructed according to actual needs. Completely guarantee the safety of workers, including the protection of workers' heads and the risk that workers may fall from high altitudes, so this kind of worker safety protection device and protection method for road and bridge construction is designed. Contents of the invention [0003] The purpose of the present invention is to solve the problem that it is difficult for workers to avoid injury caused by workers falling from a high place when reinforcing the steel bars inside bridge piers on scaffolding, and to...
