Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road outdoor detection, and particularly relates to a pollution prevention device for an asphalt concrete surface layer core drilling machine. BACKGROUND

[0002] In recent years, although many detection methods and devices have emerged in the construction of asphalt concrete highways due to the rapid development of science and technology, no unified standard and system has been formed, and they cannot be used as engineering quality judgment basis, so the original regulations and standards are still used for detection in the whole process of quality control and detection. Among them, the standard method for detecting the compaction degree of the asphalt concrete surface layer is the core drilling method.

[0003] In the specific operation, the core drilling machine is used for core sampling, and after sampling, the core sample drilling is timely and properly backfilled. During the process of drilling the core sample on the asphalt concrete surface layer, the drill bit rotates at high speed, so cooling water is continuously injected during the operation to cool the drill bit, which causes the cooling water to mix with the dust generated during the drilling process on the ground to form sewage, and the sewage is splashed outward under the action of centrifugal force, so that the operator, the core drilling machine and the asphalt concrete surface layer are all contaminated by the sewage, and the sewage and cement slurry will contaminate and penetrate into the already paved asphalt surface layer and the lower layer. Once contaminated, the newly paved asphalt surface layer is difficult to clean.

[0004] In the prior art, this problem is mostly handled passively, that is, a cylindrical structure for preventing splashing is sleeved outside the drill bit during drilling, and then the sewage is connected to an external collection device through a flow guide pipe or a sewage discharge pipe for collection. This way, an additional collector needs to be connected externally, which makes the sewage flow along the backflow pipe or the sewage discharge pipe only when a certain water level is reached. Once a certain water level is deposited at the drilling position, the deposited sewage will inevitably spread outward along the cylindrical structure if it is not discharged in time, thereby greatly limiting the effect of pollution prevention, and the external connection of the collector is inconvenient in operation. Therefore, how to efficiently and conveniently prevent the pollution of the asphalt surface layer during the core drilling sampling process has become a technical problem to be solved in the industry.

DETAILED DESCRIPTION

[0032] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments.

[0034] In the description of the embodiments of the present application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] In the description of the present specification, the description of the terms "specific embodiments", "some embodiments", "in specific examples", and the like means that the specific features, structures, materials or characteristics described in connection with the embodiments or examples are included in at least one embodiment or example of the embodiments of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples. In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the present specification and the features of the different embodiments or examples without contradiction.

[0036] As shown in Figure 1 Some common core drillers anti-pollution devices, including anti-splashing cylinder, the anti-splashing cylinder is connected with the drain pipe, the free end of the drain pipe is connected with the sewage collection device; in the connection, the anti-splashing cylinder is connected to the area of the drilling position of the drill bit, so that during the drilling process of the drill bit, the sewage is collected through the anti-splashing cylinder, and then the sewage is discharged through the drain pipe. It can be seen that such equipment needs to adjust the position of the sewage collection device below the water inlet position of the drain pipe, so that the sewage can flow through the drain pipe, so that the installation and adjustment are complex and limited by the ground environment. Based on this, the present application provides a core drill anti-pollution device capable of main sewage transportation.

[0037] The present application is described below Figures 2-5 An asphalt concrete surface core drill anti-pollution device is described, which is configured to be used during the asphalt concrete surface coring process, comprising a base 200, a sleeve 300, a water storage part 400 and a water absorption layer 100, the base 200 has an annular through hole in the middle; the sleeve 300 is connected to the base 200 and extends in the vertical direction of the base 200, a plurality of transmission grooves 303 are configured along the extension direction of the inner wall of the sleeve 300, and a transmission device 600 suitable for transmitting sewage in the vertical direction is arranged in each transmission groove 303; the water storage part 400 is connected to the outer wall of the sleeve 300, and the water storage part 400 is connected with the transmission groove 303 to enable the transmission device 600 to transmit the sewage into the water storage part 400; the water absorption layer 100 is connected to the bottom of the base 200 and is suitable for being adsorbed by the water absorption material in the water absorption layer 100.

[0038] The bottom surface of the base 200 is connected with the water absorption layer 100, which is made of flexible material and can seal the bottom of the base 200 under certain pressure, so that the splashed sewage can be deposited into the sleeve 300 and then be transmitted into the water storage part 400 by the transmitter 600. The transmitter 600 is arranged in the transmission groove 303 in a rotating manner, so that the transmitter 600 can rotate, and the driving force of the rotation can be obtained by the rotation of the drill bit 800 of the core drilling machine, that is, the drill bit 800 is matched with the transmitter 600, so that the rotation of the drill bit 800 can drive the rotation of the transmitter 600, thereby realizing the transmission of the sewage at the bottom to the water storage part 400 in the vertical direction. This can transmit the sewage into the water storage part 400 by the transmitter 600 when there is any amount of deposited water at the bottom, so that the sewage treatment is more timely and efficient.

[0039] The material of the water absorption layer 100 is a high polymer sponge adsorption pad, which has a certain elastic deformation capacity and also has water absorption capacity, which can seal the internal environment of the sleeve 300 under certain pressure and effectively prevent the spread of sewage.

[0040] In some embodiments, as shown in Figure 4 The transmitter 600 includes a spiral feeding part, which includes a rotating shaft 601, a spiral blade connected to the rotating shaft 601, and a spiral baffle 602 connected to the spiral blade. The outer wall of the spiral baffle 602 has a flexible contact layer 602-1, which is suitable for being driven by contacting the drill bit 800 of the core drilling machine.

[0041] The bottom of the spiral feeding part extends to the bottom end of the base 200, so that the sewage at the bottom can be vertically transmitted along with the rotation of the spiral feeding part and then be separated into the water storage part 400 after being transmitted to the top, thereby realizing the storage of the sewage.

[0042] The multiple spiral feeding parts can adjust the rotation direction of the spiral blade according to the different positions when arranged, for example, the rotation directions of the opposite sides are set in opposite spiral directions, so that the rotation directions of the two symmetrical sides are different and the transmission of the sewage can be performed at the same time, thereby improving the efficiency of the transmission of the sewage.

[0043] It can be understood that, as Figure 6As shown, the drill bit 800 is rotated downward to realize ground core sampling, the flexible contact layer 602-1 is in contact with the outer wall of the drill bit 800 in rotation, and the flexible contact layer 602-1 generates friction with the outer wall in contact, and since the screw feeding part is a rotating arrangement itself, this makes it only need a small friction to drive the screw feeding part to rotate, thereby realizing the vertical transmission of sewage. The whole transmission structure is simple and easy to prepare, and the transmission mode is more efficient than the passive transmission in the prior art.

[0044] In a specific example, as shown in Figure 4 The positioning part 500 is detachably connected to the top of the transmission groove 303 and is suitable for positioning one end of the rotating shaft 601.

[0045] One end of the rotating shaft 601 of the screw feeding part is rotatably connected to the bottom of the base 200, and the other end of the rotating shaft 601 of the screw feeding part is rotatably connected through the positioning part 500, so that it can rotate around the rotating shaft 601 under the driving of the friction of the drill bit 800 of the coring machine, and the screw blade will continuously transport the sewage at the bottom in the process of rotation, so that the sewage at the bottom can be discharged in time. The detachable connection of the positioning part 500 facilitates maintenance or replacement of the screw feeding part after a certain length of time.

[0046] In some embodiments, as shown in Figure 2 The top of the positioning part 500 has a flange connection disc 501, so that the positioning part 500 is connected to the top of the sleeve 300 through bolts to realize detachable connection. The positioning part 500 includes a flange connection disc 501, a matching part 502, and a support rod 503. The matching part 502 is connected to the flange connection disc 501, the flange connection disc 501 is a semicircular disc, and the matching part 502 cooperates with the inner wall of the transmission groove 303. The support rod 503 is connected to the matching part 502, and the end of the support rod 503 has a rotating hole matched with the rotating shaft 601 of the screw feeding part. The rotating shaft 601 is connected to the rotating hole through a shaft sleeve, so that the rotating shaft 601 can be positioned in the axial direction and can rotate.

[0047] It can be understood that the two ends of the rotating shaft 601 can also be rotated through a connecting bearing, that is, the two ends of the rotating shaft 601 are connected to the inner rings of the bearings, respectively, and the outer ring of one end bearing is arranged at the end of the support rod 503, and the outer ring of the other end bearing is arranged on the bottom of the sleeve 300. Of course, a bearing can also be provided at only one end.

[0048] Specifically, the overall structure of the screw feeding part can adopt hard plastic, and a flexible contact layer 602-1 is arranged outside the spiral baffle 602 of the hard plastic. The spiral baffle 602 rotates by the friction force generated by the contact between the flexible contact layer 602-1 and the rotating drill bit 800. Since the screw feeding part is rotationally connected, the contact friction is rolling friction, and the generated friction force is small, which does not affect the normal work of the drill bit 800.

[0049] The flexible contact layer 602-1 is one of a high polymer sponge layer, a brush layer, a rubber layer, and a silica gel layer. That is, one of the above materials is connected to the outer wall of the spiral baffle 602 as the flexible contact layer 602-1. The flexible contact layer 602-1 can be in contact with the drill bit 800 of the drill core machine and elastically deformed, so as to have a friction force with the outer wall of the drill bit 800. When the drill bit 800 rotates, the spiral feeding part is driven to rotate by the friction force of the contact.

[0050] It can be understood that in the above embodiment, each material layer is a material that exists, and how to connect each material layer on the outer wall surface is a conventional connection process in the art, and will not be described here.

[0051] In a specific embodiment, a communication hole 301 is machined on the inner wall of the transmission groove 303, and the communication hole 301 is adapted to communicate the water storage part 400 and the transmission device 600.

[0052] The communication hole 301 is machined at the top of the screw feeding part, that is, at the top of the spiral blade. Specifically, the communication hole 301 is machined into a through hole with a generally long strip structure, which enables the area of the communication hole 301 to cover the entire diameter of the inner wall of the transmission groove 303. The size of the communication hole 301 is designed to enable more sewage flow. The water storage part 400 is sleeved outside the sleeve 300, and the water storage part 400 is connected to the bottom of the base 200, so that the water storage part 400 is lower than the position of the communication hole 301, so that the sewage can flow into the water storage part 400 through the communication hole 301.

[0053] The bottom of the water storage part 400 has a clamping protrusion 402, and a clamping groove 202 is correspondingly formed on the base 200. The clamping protrusion 402 and the clamping groove 202 cooperate to achieve clamping. The bottom of the water storage part 400 is fixed to the base 200, and the freedom degrees of the water storage part 400 in the circumferential and vertical directions are limited.

[0054] Specifically, the clamping protrusion 402 is roughly in the shape of a "T", corresponding to the roughly "T"-shaped clamping groove 202 on the base 200, and when clamping, the clamping protrusion 402 is aligned with the clamping groove 202 and then rotated by a certain angle to be clamped into the clamping groove 202, so that the water storage part 400 is more stable and the reliability of the device as a whole is improved.

[0055] As shown in Figure 3 , the water storage part 400 is connected with a drain 401, and the connection of the drain 401 allows the stored water in the water storage part 400 to be drained when needed.

[0056] Further, a valve is connected at the position of the drain 401, and the valve is connected at the position of the drain 401, so that the drain 401 can drain sewage according to the level of the liquid, and the sewage in the water storage part 400 can be managed.

[0057] It can be understood that the valve is connected to some simple water treatment device, for example, it can be connected to a sedimentation device for sedimentation treatment of sewage, so that the sewage can be recycled after simple treatment, and the utilization rate of the sewage can be improved.

[0058] In a specific embodiment, as shown in Figure 4 , a limiting groove 302 is further processed on the outer wall of the upper part of the sleeve 300, and a limiting snap spring 700 is connected in the limiting groove 302 to limit the water storage part 400.

[0059] The bottom of the water storage part 400 is clamped and positioned by the clamping protrusion 402, which limits the freedom of the bottom, and since the drill bit 800 rotates at high speed during water taking, it will inevitably vibrate to some extent, and in order to further improve the reliability of the connection of the water storage part 400, the limiting snap spring 700 is arranged at the top of the water storage part 400 to further limit the top of the water storage part 400, thereby improving the reliability of the connection of the water storage part 400.

[0060] In some embodiments, as shown in Figure 5 , the base 200 has a fixing screw hole 201, which is adapted to pass through the fixing screw hole 201 to fix the base 200 to the ground in a predetermined area.

[0061] As can be seen from the above embodiments, in the scheme of the present application, the drill bit 800 on the drill core machine will contact the outer wall of the spiral feeding part to produce rolling friction, and the generation of this friction will cause the entire anti-pollution device to vibrate to some extent, so that the base 200 can be fixed to the ground by the fixing screw hole 201 to make the base 200 more stable and improve the reliability during sampling.

[0062] It can be understood that the setting of the fixing screw hole 201 makes the base 200 apply pressure to the bottom water absorption layer 100, so that the bottom absorption layer can have better sealing performance, further improving the anti-pollution efficiency of the application, which can effectively prevent the spread of sewage.

[0063] Through the description of the above embodiments, those skilled in the art can clearly understand that the setting of the sleeve 300 can effectively prevent splashing sewage, and since the inner wall of the sleeve 300 is provided with a plurality of spiral feeding parts, the anti-pollution device of the application can actively discharge the sewage deposited inside, improve the efficiency of sewage treatment, improve the timeliness of sewage treatment, prevent further pollution of the sewage to the asphalt pavement and prevent the expansion of pollution; further, the ground of the base 200 is connected with the water absorption layer 100, and the water absorption layer 100 adopts a high polymer sponge pad, which can play the role of a sealing pad under pressure, preventing the spread of sewage, and can absorb water in time to prevent the spread of sewage to the bottom layer of the asphalt pavement; further, the whole device is convenient to carry, has good anti-pollution effect, and avoids unnecessary waste of water resources for flushing the ground.

[0064] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
