Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering construction, and more specifically, to a safety protection device for municipal engineering construction and an installation method thereof. Background Art

[0002] During the construction of municipal engineering projects, safety protection devices are important facilities to ensure the safety of personnel around the construction area and reduce the impact of construction noise and dust on the surrounding environment. Although traditional safety protection devices, such as simple fences or baffles, can play a role in isolation and warning to a certain extent, they still have many shortcomings in actual application.

[0003] First, traditional safety protection devices often use fully enclosed settings. Although they can effectively isolate construction noise and dust, long-term fully enclosed status will lead to poor air circulation in the construction area, affecting the working environment of construction workers, and may even cause safety accidents due to environmental factors such as lack of oxygen and high temperature. Secondly, municipal engineering construction often has a long period and a large area, and the needs for safety protection in different construction stages are also different. For example, in the earth excavation stage, it is necessary to better control the spread of dust, while in the concrete solidification stage, more attention may be paid to ventilation effects. However, traditional safety protection devices are insufficient in flexibility and are difficult to meet these diverse needs.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a safety protection device for municipal engineering construction, including: at least two columns 4, which are arranged on the periphery of the construction area; a baffle assembly, installed between two adjacent columns 4, the baffle assembly includes two outer baffles 1 and inner baffles 3, each with a ventilation hole 5, the outer baffle 1 and the inner baffle 3 are relatively arranged between each two adjacent columns 4, and the outer baffle 1 and the inner baffle 3 can slide relative to each other; a driving assembly 9, which is installed on the column 4 and connected to the inner baffle 3, and is used to drive the inner baffle 3 to slide relative to the outer baffle 1 along a preset trajectory; wherein, when the ventilation holes 5 of the outer baffle 1 and the inner baffle 3 are aligned, the safety protection device is in a ventilated state, and when the ventilation holes 5 of the outer baffle 1 and the inner baffle 3 are staggered, the safety protection device is in a closed state.

[0033] When the above-mentioned safety protection device is working, when it is necessary to improve the air circulation inside the construction area, the driving component 9 is started to drive the inner baffle plate 3 to slide to a position aligned with the ventilation hole 5 of the outer baffle plate 1, so that the air inside the construction area can be exchanged with the external environment through the ventilation hole 5 to achieve a ventilation effect; when it is necessary to control the diffusion of noise and dust in the construction area, the driving component 9 drives the inner baffle plate 3 to slide to a position staggered with the ventilation hole 5 of the outer baffle plate 1, so that a closed barrier is formed between the outer baffle plate 1 and the inner baffle plate 3, which effectively isolates the noise and dust in the construction area.

[0034] In the above manner, by setting a slidable outer baffle 1 and inner baffle 3, and equipping a drive assembly 9 to adjust the relative position between the two, the safety protection device can flexibly adjust its ventilation state. When the construction area needs ventilation, the ventilation holes 5 of the outer baffle 1 and the inner baffle 3 can be aligned to achieve air circulation, improve the working environment of the construction personnel, and avoid problems such as hypoxia and high temperature caused by long-term closure. When it is necessary to control the spread of noise and dust, the ventilation holes 5 of the outer baffle 1 and the inner baffle 3 can be staggered to put the device in a closed state, effectively isolating the noise and dust in the construction area and reducing the impact on the surrounding environment.

[0035] In this embodiment, Figure 2 and Figure 4 As shown, a slot 42 is provided between two adjacent columns 4 near the outer side of the construction area, and the outer baffle 1 is inserted and fixed in the slot 42, which can effectively improve the installation efficiency of the outer baffle 1. A rotation groove 43 with a first opening at the top is provided above the two columns 4 near the inner side of the construction area, and a slide groove with a second opening on one side is provided below. A rotation shaft 31 is fixed on the top of the inner baffle 3, and a fixed shaft 32 is connected to the bottom along the longitudinal sliding. The rotation shaft 31 is connected to the rotation groove 43 along the first opening, and a clamping block 8 is connected to the slide groove along the transverse sliding. The fixed shaft 32 is clamped and fixed to the clamping block 8 along the second opening. At the same time, the fixed shaft 32 and the inner baffle 3 can slide, so that the longitudinal distance of the fixed shaft 32 can be adjusted, and it can be adaptively clamped on the clamping block 8. The driving assembly 9 is suitable for driving the clamping block 8 to slide along the transverse direction to drive the inner baffle 3 to slide relative to the outer baffle 1.

[0036] In this embodiment, the clamping block 8 includes a main body 81, a C-shaped clamping mouth arranged on the inner side of the main body 81, and a limiting block 82 arranged on the outer side of the main body 81. The limiting groove is arranged in the same direction as the slide groove. The column 4 is provided with a limiting groove in the slide groove. The limiting block 82 is slidably adapted in the limiting groove. The main body 81 is provided with a limiting rib 83 in the C-shaped clamping mouth. A connector is fixed on the fixed shaft 32. The connector is clamped in the C-shaped clamping mouth between the two limiting ribs 83. A closing plate 84 is arranged on the inner side of the limiting rib 83 away from one end of the inner baffle plate 3. The setting of the limiting rib 83 not only limits the opening range of the C-shaped clamping mouth to prevent the connector from accidentally falling out, but also the closing plate 84 added on the inner side of the limiting rib 83 away from one end of the inner baffle plate 3 further enhances the sealing and safety of the clamping structure, prevents dust, moisture, etc. from invading the slide groove, and prolongs the service life.

[0037] In this embodiment, a countersunk hole is provided on the connecting head, and a threaded hole is provided on the main body 81 at a position opposite to the countersunk hole, and a pan head bolt is connected between the countersunk hole and the threaded hole.

[0038] In this embodiment, Figure 4 As shown, the driving assembly 9 includes an electric cylinder 91 and a connecting block 92. A groove is provided on the column 4 on one side of the clamping block 8. The cylinder body of the electric cylinder 91 is embedded and fixed in the groove. The connecting block 92 is fixedly connected between the output end of the electric cylinder 91 and the clamping block 8.

[0039] In this embodiment, Figure 1 As shown, a handle 6 is provided on the lower side of the inner baffle plate 3 , and the handle 6 is suitable for lifting the inner baffle plate 3 upward around the rotation axis 31 , so as to facilitate cleaning of the internal space between the outer baffle plate 1 and the inner baffle plate 3 .

[0040] In this embodiment, Figure 5 As shown, an intermediate groove 41 is provided on two adjacent columns 4 between the outer baffle plate 1 and the inner baffle plate 3, and a dustproof net 2 is detachably connected in the intermediate groove 41. The dustproof net 2 includes a plurality of hard support rods, and the hard support rods are crisscrossed to form a plurality of grids, and a plurality of nose hair-shaped activated carbon fiber needles 21 are respectively provided on the hard support rods facing each grid.

[0041] In the above method, the dustproof net 2 can effectively block and filter impurities such as dust and particulate matter in the air, keeping the outside of the construction area clean. The activated carbon fiber needle 21 adopts bionic nose hair, which not only increases the filtering area, but also due to its adsorption properties of activated carbon, can further adsorb harmful gases and odors in the air, providing a purer air environment.

[0042] In this embodiment, a top cover is detachably connected to the outer baffle 1, the dust screen 2 and the inner baffle 3 between the two columns 4 by a first bolt, and a cover plate 7 that can close the second opening is detachably connected to the column 4 by a second bolt. The setting of the top cover effectively closes the space above the outer baffle 1, the dust screen 2 and the inner baffle 3, preventing the intrusion of dust, rainwater and other debris, and the installation of the cover plate 7 closes the second opening of the chute, further enhancing the overall sealing performance.

[0043] In this embodiment, the ventilation holes 5 are arranged in an elliptical shape, and the longest axis of the ventilation opening is arranged in the longitudinal direction, so that when the outer baffle plate 1 and the inner baffle plate 3 slide relative to each other left and right, only a small sliding stroke is required to align or stagger the ventilation holes 5. The ventilation holes 5 are arranged in an array in plurality to form a mesh.

[0044] The present invention also discloses a method for installing a safety protection device for municipal engineering construction, comprising the following steps:

[0045] S1. Install columns 4 at the periphery of the construction area according to the target spacing;

[0046] S3, insert the outer baffle 1 into the slot 42;

[0047] S4, first install the rotating shaft 31 of the inner baffle 3 into the rotating groove 43 along the first opening, then rotate the inner baffle 3 around the rotating shaft 31, so that the fixed shaft 32 of the inner baffle 3 is clamped into the C-shaped bayonet of the clamping block 8, and fix the inner baffle 3 to the clamping block 8 by means of pan head bolts;

[0048] S5. Install the top cover and cover plate 7.
