Problems solved by technology

However, this device is troublesome in the installation process of the protective net, which is time-consuming and labor-intensive. At the same time, it is necessary to ensure that the distance between adjacent fixing rods is consistent with the length of the protective net. If the protective net is too short, it cannot be installed. easy to fall off

Embodiment 1

[0018] see figure 1 , figure 2 and image 3 , a bridge construction protection device, comprising an upper column 1, a protective plate installation plate 2, a protective plate 3 and an installation base 4, the number of the upper column 1 is two, and the left and right upper column 1 are mirror symmetrically arranged, and the left and right two The opposite surface of the upper column 1 is welded and fixed with a protective plate installation insert 2, and a protective plate 3 is clamped between the left and right protective plate installation inserts 2, and the lower part of the upper column 1 is provided with a mounting base 4; the lower end of the upper column 1 It is fixedly connected with the lifting mechanism 5, and the bottom of the lifting mechanism 5 is fixed on the lower column 9. The height of the whole device can be adjusted through the lifting of the lifting mechanism 5, which can adapt to the height requirements of different protective plates and greatly impro...

Embodiment 2

[0020] see figure 1 and image 3 In this embodiment, on the basis of Embodiment 1, the lifting mechanism 5 includes a bearing 6, a lifting rotating shaft 7 and a mounting hole 8, and the top of the lifting rotating shaft 7 is installed on the bottom of the upper column 1 through the bearing 6, and the lifting rotating shaft The bottom thread of 7 is installed in the mounting hole 8, and the mounting hole 8 is opened on the upper surface of the lower column 9; Anti-slip lines 14 are processed on the surface to increase friction and play an anti-slip effect.

[0021] The working principle of the present invention is: the height of the whole device can be adjusted through the lifting of the lifting mechanism 5, which can adapt to the height requirements of different protective plates and greatly improves the practicability; the left and right sides of the lifting mechanism 5 are also provided with guide mechanisms 10 , the guide mechanism 10 can ensure the stability of the uppe...

Abstract

The invention relates to the technical field of bridge construction devices, and specifically discloses a bridge construction protection device, which comprises an upper part vertical column, a protective plate mounting inserting plate, a protective plate, and a mounting base. The lower end of the upper part vertical column is fixedly connected with a lifting mechanism, the lower part of the lifting mechanism is fixed to a lower part vertical column; guiding mechanisms are arranged on the left and right sides of the lifting mechanism, the guiding mechanisms comprise guiding rods and guiding rod mounting holes, the top ends of the guiding rods are fixedly connected on the lower end surface of the upper part vertical column in a welding mode, the bottom ends of the guiding rods are mounted in the guiding rod mounting holes in a clamping mode, and the guide rod mounting holes are opened on the upper end surface of the lower part vertical column; and the bottom end of the lower part vertical column is slidably mounted in a sliding groove, the sliding groove is opened on the upper end surface of the mounting base, and the lower part vertical column is fixed by a pressing mechanism. Thebridge construction protection device has the advantages of being simple in structure and low in cost, mounting of the protective plate is convenient and quick, meanwhile the height of the whole device can be adjusted, practicability is extremely high, and the protection effect is good.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a bridge construction protection device. Background technique [0002] In the process of bridge construction, most of the construction workers work at heights, so good bridge construction protection devices are needed to ensure the personal safety of the construction workers. In the prior art, protective nets are usually used for protection. The protective nets are easy to break and the protection effect is poor. [0003] Chinese patent (notification number: CN108797353A, announcement date: 2018.11.13) discloses a protective device for bridge construction, including a first fixing rod, a second fixing rod, a fixing mechanism, a first hook, a second hook, etc.; and The output end cooperates with the second fixed rod; a plurality of equidistant first hooks are affixed to the first fixed rod and one side of the second fixed rod, and a plurality of second hooks ...
