Problems solved by technology

[0003] During the inspection of the catenary reserved foundation, the progress in front of the station is basically in the stage of bridge pier construction. There are only bridge piers on site, without beams and other auxiliary tools such as scaffolding, and there is no reliable position on the bridge piers where safety belts can be hung

Embodiment 1

[0030] Such as figure 1 As shown, a safety belt suspension device for inspection of catenary bridge pier foundation interface includes a main rod 1 , a first support 2 , a second support 3 and a plurality of expansion and fixing components 4 . The device can be installed in the reserved hole of the pad stone of the bridge pier, and is used to hang the safety belt, so as to ensure personal safety and construction safety.

[0031] Specifically, the main rod 1 includes a rod body 11 and a hooking portion 14 fixed to an end of the rod body 11 . The rod body 11 is provided with a first threaded portion 12 and a second threaded portion 13 , and the threads of the first threaded portion 12 and the second threaded portion 13 have opposite directions of rotation. The first supporting member 2 is sleeved on the rod body 11 and screwed to the first threaded portion 12 ; the second supporting member 3 is sleeved on the rod body 11 and screwed to the second threaded portion 13 . In this ...

Embodiment 2

[0043] refer to figure 1 As shown, in the present embodiment, the material selection of each component of the catenary bridge pier foundation interface inspection safety belt suspension device is:

[0044] Component 1: rod body 11, made of a cylindrical solid metal piece (such as Q235 steel), with a size of φ30mm*700mm. The first threaded part 12 and the second threaded part 13 are formed on the outer contour of the rod body 11, and both have a length of 150 mm.

[0045] Component 2: the articulated part 14 is made of metal, ring-shaped, with an inner diameter of 50mm, an outer diameter of 60mm, and a thickness of 10mm. It is mainly used for rotating the main rod 1 and suspending the safety belt.

[0046] Component 3: the first support 2 and the second support 3, made of metal, with an inner diameter of 30 mm, an outer diameter of 40 mm, and a thickness of 15 mm. The inner side of the first support member 2 has internal threads matching the first threaded portion 12 ; the in...

Embodiment 3

[0052] refer to image 3 As shown, the difference between this embodiment and Embodiment 1 is that the first auxiliary arm 42 and the second auxiliary arm 43 are respectively hinged to the fixed arm 41 through different pin shafts. Specifically, one end of the first auxiliary arm 42 is hinged with the first support member 2, and the other end is hinged with the fixed arm 41 at the first position a; one end of the second auxiliary arm 43 is hinged with the second support member 3, and the other end is at the first position a. The second position b is hinged with the fixed arm 41 ; the height position of the first position a is higher than the first support member 2 and the height position of the second position b is lower than the second support member 3 . When the first support 2 and the second support 3 move away from each other, the first auxiliary arm 42 and the second auxiliary arm 43 will push the fixed arm 41 outward, so as to realize the fixing of the device and the res...

Abstract

The invention discloses a safety belt suspension device for inspecting the foundation interface of catenary bridge pier, and relates to the technical field of safety belt suspension tools. Wherein, the main rod includes a rod body and a hooking part fixed on the end of the rod body, the rod body is provided with a first threaded part and a second threaded part, and the threads of the first threaded part and the second threaded part have opposite helical directions; the first support member Sleeved on the rod body and screwed with the first threaded part; the second support member is sleeved on the rod body and screwed with the second threaded part; each expansion fixation assembly includes a fixed arm, a first auxiliary arm and a second auxiliary arm One end of the first auxiliary arm is hinged to the first support, and the other end is hinged to the fixed arm at the first position; one end of the second auxiliary arm is hinged to the second support, and the other end is hinged to the fixed arm at the second position. The device is used to hang safety belts to ensure personal safety and construction safety.

Description

technical field [0001] The invention relates to the technical field of safety belt suspension tools, in particular to a safety belt suspension device for inspecting catenary pier foundation interfaces. Background technique [0002] At present, in the construction of railway projects, more and more attention is paid to the reservation and inspection quality of the interface between the station and the four power stations, which is directly related to the effectiveness of all follow-up work of the four power majors. Among them, the basic reserve inspection of the catenary is the most important. [0003] During the inspection of the catenary reserve foundation, the progress in front of the station is basically in the stage of bridge pier construction. There are only bridge piers on site, without beams and other auxiliary tools such as scaffolding, and there is no reliable position on the bridge piers where safety belts can be hung. When working at heights, the safety belt is th...
