Description

Technical Field

[0001] The utility model relates to the technical field of dust-proof equipment, in particular to a floor-hugging dust suppressing device. Background Art

[0002] A hydraulic rotary drilling device is a mechanical equipment for drilling, which is widely used in the fields of construction, mining, petroleum, natural gas, geological exploration, etc. It uses a hydraulic system to provide power and drills by rotating, and can efficiently complete drilling tasks with different diameters and depths. During the drilling process, the drill bit exerts force on materials such as rocks and concrete, breaking them into small particles or powdery substances. These fine particles are suspended in the air to form dust. If no appropriate dust reduction measures are taken, the fine particles generated during the drilling process are easily dispersed into the surrounding environment, causing serious dust problems. Currently, a dust-proof cover is usually installed on the carriage of the drilling rig to avoid dust scattering. However, since the dust-proof cover is always in contact with the ground, it has a large amount of wear and needs to be replaced frequently. Moreover, when perforating an uneven surface, air leakage and dust leakage are likely to occur, causing a large environmental protection risk.

[0003] Based on the above situation, we propose a floor-hugging dust suppressing device to solve the above problems. Summary of the Utility Model

[0004] The utility model provides a floor-hugging dust suppressing device to solve the problem that in the prior art, during the perforation operation on an uneven surface, air leakage and dust leakage are likely to occur in the dust-proof cover, causing a large environmental protection risk.

[0005] The technical problems solved by the utility model are realized by the following technical solutions:

[0006] A floor-hugging dust suppressing device includes a carriage installed on a drilling rig. A connecting seat is installed at the bottom end of the carriage. An annular elastic dust suppressing member with two open ends is arranged below the connecting seat. The elastic dust suppressing member is used to suppress the dust generated during the drilling of the drill pipe.

[0007] The elastic dust suppressing member includes an installation part detachably connected to the bottom of the connecting seat and an elastic connecting part integrally formed with the installation part. The cross-section of the elastic connecting part is arc-shaped.

[0008] Preferably, one end of the elastic connecting part away from the installation part is connected with a receiving part with an upward opening, and the cross-section of the receiving part is concave downward.

[0009] Preferably, at least two groups of gap grooves are formed on the receiving part, and at least two groups of the gap grooves divide the receiving part into a plurality of receiving members.

[0010] Preferably, it further includes an arc-shaped gasket provided on the inner wall of the installation part, and the arc-shaped gasket is detachably connected to the connecting seat by bolts.

[0011] Preferably, when the elastic dust suppression member is installed on the carriage, the elastic dust suppression member protrudes from the bottom end of the carriage.

[0012] Preferably, the number of the arc-shaped gaskets is multiple groups, and they are arranged at equal intervals along the central axis of the elastic dust suppression member.

[0013] The beneficial effects of the present utility model are as follows: By installing an elastic dust suppression member at the front end of the carriage, and under the action of the ductility of the elastic connection part, the elastic connection part is in closer contact with the drilling plane, and can cover the periphery of the perforation position during the drilling process, effectively eliminating the phenomenon of dust and ash escaping from the hole mouth during the perforation operation and reducing environmental pollution.

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0021] Refer to Figures 1-4As shown in the figure, a ground-pressing dust suppression device includes a carriage 1 installed on a drill rig. A connecting seat 2 is installed at the bottom of the carriage 1. Below the connecting seat 2, there is an annular elastic dust suppression member 3 with openings at both ends. The elastic dust suppression member 3 can be used to suppress the dust generated during the drilling of the drill pipe. The elastic dust suppression member 3 can coincide with the axis of the drill pipe, and a through hole for the drill pipe to pass through is opened on the connecting seat 2. When the carriage 1 contacts the drilling contact surface, one end of the drill pipe passes through the through hole and the elastic dust suppression member 3 for drilling operations. The size of the through hole is slightly larger than the diameter of the drill pipe, which facilitates the drill pipe to extend into the drill hole through the through hole and also reduces the overflow of dust in the drill hole from the through hole. The elastic dust suppression member 3 contacts the drilling operation surface and surrounds the outer periphery of the hole. When dust is generated during drilling, it is intercepted by the elastic dust suppression member 3, reducing dust overflow;

[0022] Specifically, the elastic dust suppression member 3 includes a mounting portion 31 detachably connected to the bottom of the connecting seat 2 and an elastic connecting portion 32 integrally formed with the mounting portion 31. The cross-section of the elastic connecting portion 32 is arc-shaped. After the elastic dust suppression member 3 contacts the drilling operation surface, the elastic connecting portion 32 is compressed and deformed, so that the elastic connecting portion 32 can have a better ground contact effect, which is suitable for sealing and dust suppression on some uneven ground. When the elastic dust suppression member 3 is released from contacting the drilling operation surface, it returns to its original shape under the elastic action of the elastic connecting portion 32.

[0023] Refer to Figure 4 As shown in the figure, further, one end of the elastic connecting portion 32 away from the mounting portion 31 is connected with a receiving portion 33 with an upward opening, and the cross-section of the receiving portion 33 is concave downward. The dust and the like intercepted by the elastic dust suppression member 3 can be partially collected into the receiving portion 33 for temporary storage. The material of the receiving portion 33 and the elastic connecting portion 32 can be the same or integrally formed. For example, using waste tires and other items can be used as the elastic dust suppression member 3, which can improve the friction between the elastic dust suppression member 3 and the drilling operation surface, thereby extending its service life. At the same time, waste tires and the like can also be recycled for resource conservation.

[0024] Among them, at least two groups of gap grooves 4 are opened on the receiving portion 33, and at least two groups of gap grooves 4 divide the receiving portion 33 into multiple receiving members. By opening the gap grooves 4, it is convenient to separate the annular receiving portion 33, so as to fold the receiving members, thereby facilitating the cleaning of the dust and the like collected inside the receiving members.

[0025] Refer to Figure 3As shown in the figure, further, it also includes an arc-shaped gasket 5 provided on the inner wall of the installation part 31. The arc-shaped gasket 5 can be a sheet-shaped object made of plastic or metal. The arc-shaped gasket 5 is detachably connected to the connecting seat 2 through a bolt 51. The elastic dust suppression part 3 is clamped by the arc-shaped gasket 5 and the connecting seat 2 to realize the installation and fixation of the elastic dust suppression part 3. And in the case where the elastic dust suppression part 3 is severely worn and needs to be replaced, etc., it is convenient for the disassembly and assembly of the elastic dust suppression part 3.

[0026] Among them, the number of the arc-shaped gaskets 5 is multiple groups, and they are arranged at equal intervals along the central axis of the elastic dust suppression part 3, which can improve the connection stability between the elastic dust suppression part 3 and the connecting seat 2, reduce the existence of gaps between the installation part 31 and the connecting seat 2, and thus reduce the possibility of dust leaking from the gaps between the installation part 31 and the connecting seat 2.

[0027] Further, when the elastic dust suppression part 3 is installed on the carriage 1, the elastic dust suppression part 3 protrudes from the bottom end of the carriage 1, which can make the elastic dust suppression part 3 contact with some uneven or inclined working surfaces, and increase the sealing effect between the drilling working surface and the elastic dust suppression part 3.
