Description

Technical Field

[0001] The utility model belongs to the technical field of dust prevention equipment at a pile foundation construction site, and specifically relates to a special device for reducing dust during construction of a pneumatic rock drill. Background Art

[0002] In the current pile foundation design scheme of mountain photovoltaic projects, strip foundation or cast-in-place piles are generally used due to the influence of topography and geology. In order to speed up the construction of strip foundation, it is usually necessary to build steps and open horse paths on a large scale to facilitate the later pouring construction, which is more damaging to the environment. Therefore, the current mainstream design form of pile foundation is cast-in-place pile foundation, that is, first lead the hole and then pour. This design is relatively fast during construction. It only needs to transport the air compressor to the construction road near the site, and supply gas through a rubber hose. Four or five people can operate a rock drill to carry out the hole construction without opening up additional construction roads.

[0003] The disadvantage of this solution is that when the borehole construction is carried out, the dust generated by the borehole is affected by the blowing force of the high-pressure air and will rush out of the hole, resulting in serious dust. Especially when the geology is weathered rock, this situation is more obvious. The rock dust generated not only has a serious impact on the environment, but also affects the health of the construction workers. Utility Model Content

[0004] In view of the above situation, in order to solve the defects of the prior art, the utility model provides a special device for reducing dust during the construction of a pneumatic rock drill, which reduces the dust generated by high-pressure air while ensuring the progress of the hole construction, thereby improving the protection of the environment and construction personnel.

[0005] The present application discloses a special device for reducing dust during construction of a pneumatic rock drill, which adopts the following technical solutions:

[0006] A special device for reducing dust during construction of a pneumatic rock drill, comprising a wall protection sleeve and a dust cover sleeve mounted on the rock drill;

[0007] The wall protection sleeve is detachably connected to the head of the rock drill; the upper end of the dust cover is fixedly connected to the lower end of the wall protection sleeve, and the wall protection sleeve and the dust cover cover the entire rock drill.

[0008] By adopting the above technical solution, after the drill bit of the rock drill is aligned with the drilling point and the rock drill is kept vertical, the dust cover is lowered to cover the drilling point together with the rock drill. Start the rock drill to carry out hole-guiding construction. During the process of hole-guiding, the height of the rock drill is lowered, and the dust cover is always on the ground, so that the dust cover will gradually fold, solving the impact on the depth of the hole-guiding. During the falling process of the rock drill, the redundant design of the dust cover can collect excess dust to prevent it from falling back into the hole. By implementing the above operating steps, the dust caused by hole-guiding can be effectively reduced. The presence of the high-density cloth cover also blocks the diffusion of some noise, reduces the impact on the surrounding environment during construction, and also effectively improves the health protection of the construction workers.

[0009] Preferably, an open-hole belt is installed on the upper end of the wall protection sleeve, and the open-hole belt binds the wall protection sleeve to the rock drill.

[0010] By adopting the above technical solution, the perforated belt installs the wall protection sleeve on the rock drill.

[0011] Preferably, a sealing rubber ring is fixedly connected to the upper end of the wall protection sleeve. When the wall protection sleeve is mounted on the rock drill, the sealing rubber ring abuts against the upper end of the rock drill to close the gap between the rock drill and the upper end of the wall protection sleeve.

[0012] Preferably, the dust cover is made of flexible material.

[0013] By adopting the above technical solution, the length of the dust cover can be easily adjusted.

[0014] Preferably, a bottom pressing iron plate is fixedly connected to the lower end of the dust cover; and the bottom pressing iron plate is sleeved on the rock drill.

[0015] By adopting the above technical solution, the dust removal sleeve can be prevented from floating back and forth due to the influence of compressed air under the action of the bottom pressing iron plate.

[0016] Preferably, a supporting steel ring is installed on the dust cover, and the supporting steel ring is mounted on the rock drill.

[0017] By adopting the above technical solution, the supporting steel ring can prevent the drill rod and the dust removal sleeve from being entangled.

[0018] Preferably, the supporting steel rings are provided in plurality, and the plurality of supporting steel rings are arranged on the dust cover along the length direction of the dust cover.

[0019] Preferably, the plurality of supporting steel rings are provided with different sizes and are arranged in order from small to large from top to bottom.

[0020] By adopting the technical solution, the dust cover can be easily retracted.

[0021] Preferably, a lifting handle is fixedly connected to the lower side of the dust cover.

[0022] By adopting the above technical solution, the rock drill together with the dust cover is lifted up by pulling the handle, and then the dust cover is automatically dropped by releasing the pulling handle, and the collected dust is shaken off at the same time, which will not be spread by the wind.

[0023] Preferably, two pulling handles are provided and arranged on both sides of the dust cover.

[0024] The beneficial effects of the utility model are as follows: by arranging a special device for reducing dust generated during construction of a pneumatic rock drill, dust generated during hole drilling can be effectively reduced; the presence of the high-density cloth sleeve also blocks the diffusion of some noise, reduces the impact on the surrounding environment during construction, and also effectively improves the health protection of the construction workers.

[0029] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] The utility model provides a special device for reducing dust from construction of a pneumatic rock drill. Figure 1 , Figure 2 The special device for reducing dust during construction of a pneumatic rock drill includes a wall protection sleeve 1, a perforated belt 2, a sealing rubber ring 3, a dust cover 4, a bottom pressure iron plate 5, a supporting steel ring 6 and a lifting handle 7.

[0032] The wall protection sleeve 1 is sleeved on the rock drill, and the wall protection sleeve 1 is cylindrical. Wherein, the wall protection sleeve 1 has openings at both ends.

[0033] The perforated belt 2 is connected to the upper end of the wall protection sleeve 1, and a plurality of perforated belts 2 are provided. When the wall protection sleeve 1 is sleeved on the rock drill, the perforated belt 2 is tied to the rock drill to connect the wall protection sleeve 1 and the rock drill together.

[0034] The sealing rubber ring 3 is fixedly connected to the upper end of the wall protection sleeve 1 . When the wall protection sleeve 1 is sleeved on the rock drill, the sealing rubber ring 3 abuts against the upper end of the rock drill to close the gap between the rock drill and the upper end of the wall protection sleeve 1 .

[0035] The upper end of the dust cover 4 is fixedly connected to the lower end of the wall protection sleeve 1. The dust cover 4 is made of a flexible material, such as cloth, plastic, etc., and is easily deformed when subjected to pressure. The sum of the length of the dust cover 4 opened and the length of the wall protection sleeve 1 is not less than the height of the rock drill, so that when the dust cover 4 and the wall protection sleeve 1 are mounted on the rock drill, the rock drill can be covered as a whole. When the dust cover 4 is mounted on the rock drill, there is a gap between the dust cover 4 and the rock drill.

[0036] The bottom pressing iron plate 5 is fixedly connected to the lower end of the dust cover 4. When the dust cover 4 and the wall protection sleeve 1 are sleeved on the rock drill, the lower end of the dust cover 4 naturally falls down and contacts the ground under the gravity of the bottom pressing iron plate 5, thereby covering the entire rock drill. The bottom pressing iron plate 5 is also sleeved on the rock drill.

[0037] The supporting steel ring 6 is sleeved on the dust cover 4 and fixedly connected to the dust cover 4. A plurality of supporting steel rings 6 are provided, and the plurality of supporting steel rings 6 are arranged on the dust cover 4 along the length direction of the dust cover 4. When the dust cover 4 shrinks, two adjacent supporting steel rings 6 are close to each other, and the supporting steel rings 6 support the dust cover 4 to prevent the diameter of the dust cover 4 from shrinking. The plurality of supporting steel rings 6 can also be set to different sizes, and arranged in order from small to large from top to bottom, so that when the dust cover 4 shrinks, the plurality of supporting steel rings 6 can be sleeved together.

[0038] The lifting handle 7 is fixedly connected to the lower side of the dust cover 4, and is also fixed on the supporting steel ring 6 on the lower side. Two lifting handles 7 are provided, which are arranged on both sides of the dust cover 4.

[0039] The present application discloses a method for using a special device for reducing dust during construction of a pneumatic rock drill: first, a dust cover 4 and a wall protection sleeve 1 are put on the rock drill, and the dust cover is firmly bound to the rock drill head through a hole-opening belt 2, and a sealing rubber ring 3 is pressed. The wall protection sleeve 1 can separate the rock drill head from the dust cover to prevent the dust cover from being entangled when the machine rotates. The dust cover 4 can be folded and lifted by the lifting handle 7, and transported to the construction area together with the rock drill. After the drill bit of the rock drill is aligned with the drilling point and the rock drill is kept vertical, the dust cover is lowered to cover the drilling point together with the rock drill. The rock drill is started to carry out hole-drawing construction, and the supporting steel ring 6 can prevent the drill rod from being entangled with the dust cover, and at the same time, under the action of the bottom iron plate 5, the dust cover is prevented from floating back and forth under the influence of compressed air. In the process of the hole-drawing falling, the height of the rock drill is reduced, and the dust cover 4 is always on the ground, so that the dust cover 4 will gradually fold, solving the influence on the depth of the hole-drawing. During the falling process of the rock drill, the redundant design of the dust cover can collect excess dust and prevent it from falling back into the hole. When the drilling depth reaches the design requirement, the rock drill is lifted together with the dust cover 4 by pulling the handle 7, and then the handle 7 is released, and the dust cover automatically falls, and the collected dust is shaken off and will not spread with the wind. By implementing the above-mentioned operating steps, the dust caused by drilling holes can be effectively reduced. The presence of the high-density cloth cover also blocks the spread of some noise, reduces the impact on the surrounding environment during construction, and also effectively improves the health protection of the construction workers.
