Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water conservancy and hydropower construction, and particularly relates to an anchor cable construction dust falling device. BACKGROUND

[0002] In the process of water conservancy and hydropower engineering construction, when the building construction of high slope is involved, the high slope usually needs to be supported to strengthen the strength of the slope soil body and to enhance the stability of the rock-soil body structure.

[0003] The commonly used reinforcement methods mainly include supporting structures, anchor rods, anchor holes, etc.; when anchoring the main cable in the side hole, the main cable is divided into many steel strands which are respectively anchored in the anchor spindle to improve the integrity of the slope rock mass, fundamentally improve the mechanical properties of the rock mass, effectively control the displacement of the rock mass, promote its stability, and achieve the purpose of regulating bedding, landslide, and dangerous rock and stone, so that anchor cable drilling construction is needed for convenience in later anchoring. In the prior art, high-pressure gas is usually sprayed while drilling to timely blow out the debris and dust in the hole, so that a large amount of dust is generated at the construction site, which greatly pollutes the construction site environment and threatens the health of the construction personnel.

[0004] Therefore, an anchor cable construction dust falling device is provided to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0005] The utility model provides an anchor cable construction dust falling device to solve the problem of a large amount of dust existing in the anchor cable drilling construction in the prior art.

[0006] To solve the above technical problems, the technical scheme adopted by the utility model is as follows:

[0007] An anchor cable construction dust falling device comprises:

[0008] The protective cover has a cylindrical sleeve segment in the front half and a funnel-shaped collecting box segment in the rear half; the sleeve segment is in communication with the small-diameter end of the collecting box segment; the sleeve segment is sleeved outside the anchor cable follower pipe, and the middle inner wall is provided with a rubber pad layer abutting against the outer wall of the anchor cable follower pipe; the collecting box segment is divided into a front half and a rear half by a middle stone blocking net, and a dust blocking net is arranged at the tail portion; the front half and the rear half of the collecting box segment are respectively provided with a first collecting opening and a second collecting opening in the bottom wall, and a collecting barrel is arranged below each of the first and second collecting openings; and the rear half of the collecting box segment is further provided with an atomizing nozzle at the top.

[0009] Supporting feet are respectively arranged at the bottom walls outside the sleeve segment and the collecting box segment.

[0010] In particular, the supporting feet are electric telescopic rods hingedly connected with the sleeve segment and the collecting box segment, respectively.

[0011] In particular, the bottom of each supporting foot is hingedly connected with a supporting plate.

[0012] Particularly, the top wall of the front half of the header section is provided with a fan, which is inclined towards the second aggregate outlet of the rear half of the header section.

[0013] Particularly, the inner wall of the sleeve section is further provided with a plurality of positioning blocks, the height of the positioning blocks being greater than the gap between the outer wall of the anchor cable following pipe and the inner wall of the sleeve section.

[0014] Compared with the prior art, the device has the following advantages and beneficial effects:

[0015] The protective cover is externally connected to the outside of the anchor cable following pipe through the sleeve section, thereby isolating the contact between the anchor cable following pipe and the outside, and the gravel and dust are treated separately through the funnel-shaped header section and the stone blocking net arranged in the header section, which is conducive to reducing dust pollution in the construction process of the anchor cable following pipe and effectively improving the construction site environment.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the solved technical problems, the technical features constituting the technical solutions and the brought technical effects.

[0019] As shown in the drawings, Figure 1 A dust reduction device for anchor cable construction, comprising:

[0020] The protective cover has a cylindrical sleeve section 1 in the front half and a funnel-shaped header section 2 in the rear half; the small diameter end of the sleeve section 1 communicates with the header section 2; the sleeve section 1 is sleeved on the outside of the anchor cable following pipe 3, and the middle inner wall is provided with a rubber pad layer 4 abutting against the outer wall of the anchor cable following pipe 3; the header section 2 is divided into a front half and a rear half by a middle stone blocking net 5, and the tail part is provided with a dust blocking net 6; the front half and the rear half of the header section 2 are respectively provided with a first aggregate outlet 7 and a second aggregate outlet 8 in the bottom wall, and an aggregate bucket 9 is placed below each of the first aggregate outlet 7 and the second aggregate outlet 8; the rear half of the header section 2 is further provided with an atomizing nozzle 10 on the top;

[0021] The support feet 11 are respectively arranged on the bottom walls outside the sleeve section 1 and the header section 2.

[0022] The main principle of this invention is as follows: The device is supported on the outside of the anchor cable root pipe 3 by the support foot 11, and is sleeved on the outside of the end of the anchor cable root pipe 3 by the sleeve section 1, thereby isolating the construction drilling anchor cable in the anchor cable root pipe 3 from the external environment. Then, the protective cover is installed on the anchor cable root pipe 3 by the sleeve section 1 with rubber pad 4. On the premise of ensuring stable installation, sufficient length is reserved for the rear collection section 2, and the gap between the sleeve section 1 and the anchor cable root pipe 3 is sealed by the rubber pad 4. Then, the crushed stone and dust products are separated by the rock-blocking net 5. The crushed stone cannot pass through the rock-blocking net 5 and falls into the first collection port 7 below after being blocked by the rock-blocking net 5. The dust passes through the rock-blocking net 5 and is moistened by the atomizing nozzle 10 at the top of the rear half of the collection section 2. Its weight increases and it is discharged from the second collection port 8, thus completing the treatment of construction gas and avoiding the problem of excessive dust pollution of the working environment. It should be noted that the dust barrier 6 is made of geotextile or burlap with fine pores. On one hand, it serves as a protective cover; on the other hand, it also intercepts small amounts of dust that have not absorbed water droplets, as well as some dust that has absorbed water droplets, when they come into contact with the dust barrier 6 under the influence of airflow, preventing the mixture of dust and water droplets from escaping directly from the tail end of the header section 2. To avoid clogging the pores of the dust barrier 6, it can be replaced periodically. For easy replacement, the dust barrier 6 can be fixed to the outside of the header section 2 using hooks or ties.

[0023] In a preferred embodiment, the support leg 11 is an electrically operated telescopic rod that is hinged to the sleeve section 1 and the header section 2 respectively.

[0024] In this embodiment, by hinged electric telescopic rods to the outside of the socket section 1 and the header section 2, the weight of the protective cover is supported, effectively reducing the overall stress on the socket section 1 and preventing deformation caused by the socket section 1 bearing the weight of the device for a long time. At the same time, by adjusting the length of the two electric telescopic rods, the angle of the protective cover can be adjusted so that the overall orientation of the protective cover is consistent with the anchor cable and pipe 3, increasing the versatility of this utility model device.

[0025] In a preferred embodiment, the bottom of each support foot 11 is hinged to a support plate 12.

[0026] In this embodiment, by hinged a support plate 12 to the bottom of the support foot 11, the force-bearing area at the bottom of the support foot 11 is increased, effectively increasing the stability of the device. This also avoids changes in the angle of the protective cover caused by the support foot 11 directly inserting into the soil when the soil layer is soft. By increasing the contact area with the ground through the support plate 12, the device will not shake or the sleeve joint 2 will fall off due to vibrations during anchor cable construction during actual use.

[0027] As a preferred embodiment, the front half of the header section 2 is provided with a fan 13, which is inclined towards the second aggregate outlet 8 of the rear half of the header section 2.

[0028] In the present embodiment, the fan 13 makes the overall gas flow direction towards the rear end of the header, facilitating the passage of dust-laden gas through the stone blocking net 5. At the same time, the dust blocking net 6 has a small aperture, which can effectively block dust and prevent excessive dust from escaping through the tail of the header section 2.

[0029] As a preferred embodiment, the inner wall of the sleeve joint section 1 is further provided with a plurality of positioning blocks 14, and the height of the positioning blocks 14 is greater than the gap between the outer wall of the anchor cable following pipe 3 and the inner wall of the sleeve joint section 1.

[0030] In the present utility model, the positioning blocks 14 can make the utility model device stably sleeve joint at the end of the anchor cable following pipe 3 when facing the construction scene with a long exposed part of the anchor cable following pipe 3, avoiding the direct insertion of the anchor cable following pipe 3 into the header section 2, which leads to poor dust reduction effect.

[0031] In the description of the present utility model, "connection", "fixing" can be fixed connection, machining, welding, or mechanical connection, and the specific meaning of the above terms in the present utility model is understood

[0032] In the description of the present utility model, the terms "center", "upper", "lower", "horizontal", "inner", "outer" and the like indicate the orientation or position relationship only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element must have a specific orientation, so it cannot be understood as a limitation on the present utility model.
