Description

Technical Field

[0001] The utility model relates to a breaker for underwater operation, belonging to the technical field of breakers. Background Art

[0002] The breaker plays an important role in fields such as building demolition, mine exploitation, excavation machinery, foundation exploration, and highway construction. It is mainly a device that breaks materials in an impact form, capable of destroying hard objects. Through a powerful impact force, the object can be broken into small pieces, facilitating subsequent processing and cleaning, and playing a key role in various projects, and has been widely used in various construction projects.

[0003] With the development of engineering technology, the hydraulic breaker is not only applicable to on-land breaking and demolition work, but also can be applied to underwater operations, such as ocean engineering, underwater rescue, and underwater construction. The demand for underwater operations is also increasing day by day.

[0004] However, when the breaker is operating underwater, which means the lower part or the middle and lower part or all of the breaker's housing is underwater. The reciprocating movement of the drill rod often causes the equipment to rust due to water seepage through the gaps in the housing, which will affect the service life of the breaker. Although the breaker has strengthened its sealing in the early stage, such as adding sealing rings and gaskets, etc., to ensure the tightness of each interface, even so, when the breaker is operating underwater, there will still be problems of water seepage and rust. In addition, when the breaker is operating underwater, there is also a problem of difficult lubrication between the drill rod and the bushing. There is also a problem that due to poor visibility during underwater operation of the breaker, it is impossible to know whether the breaker operating underwater is in a vertical striking state due to limited visibility, which seriously affects the work efficiency and the service life of the breaker. Summary of the Invention

[0005] The utility model aims at the deficiencies existing in the prior art and provides a breaker for underwater operation.

[0006] The technical solution for the utility model to solve the above technical problems is as follows: A breaker for underwater operation includes a housing, a drill rod and a piston that moves in the housing. The drill rod is located below the piston, and further includes an anti-seepage mechanism. The anti-seepage mechanism includes an anti-seepage channel arranged in the housing and a gas supply device that can continuously supply gas to the anti-seepage channel of the breaker for underwater operation. An accommodation cavity for the drill rod to move is arranged in the housing. An air inlet hole is arranged at the upper part of the housing, and the air inlet hole is communicated with the inlet of the anti-seepage channel. The outlet of the anti-seepage channel is communicated with the accommodation cavity.

[0007] The beneficial effects of the present utility model are as follows: When the breaker needs to operate underwater, the air supply device can continuously fill the breaker with air through the air supply pipeline. The filled air can be discharged through the gaps on the breaker to form a cycle. Due to the air pressure, water cannot enter the hammer body of the breaker, thus solving the problem of water seepage and rust during underwater operation of the breaker and extending the service life of the breaker.

[0008] On the basis of the above technical solution, the present utility model can be further improved as follows.

[0009] Further, the housing includes an upper cylinder, a middle cylinder and a lower cylinder. The accommodation cavity is arranged in the lower cylinder, and the air inlet hole is arranged on the upper cylinder.

[0013] Further, the upper flow channel includes an upper horizontal flow channel and an upper vertical flow channel. The air inlet hole is communicated with the inlet of the upper horizontal flow channel. The outlet of the upper horizontal flow channel is communicated with the inlet of the upper vertical flow channel. The outlet of the upper vertical flow channel is communicated with the middle flow channel.

[0014] The beneficial effect of adopting the above further solution is that since the top of the upper cylinder also needs to be connected with the quick connector, the air inlet hole is arranged on the side of the upper cylinder. Therefore, the upper horizontal flow channel and the upper vertical flow channel are arranged. When the breaker is operating underwater, the air inlet hole is connected with the air supply device. When underwater operation is not required, gas does not need to be introduced, and a plug can be used to seal this hole to avoid dust entering the breaker and affecting the service life of the drill rod.

[0015] Further, the lower flow channel includes a lower vertical flow channel and a lower horizontal flow channel. The inlet of the lower vertical flow channel is communicated with the middle flow channel. The outlet of the lower vertical flow channel is communicated with the inlet of the lower horizontal flow channel. The outlet of the lower horizontal flow channel leads to the accommodation cavity.

[0016] The beneficial effect of adopting the above further solution is that, in order to process the lower transverse flow channel, a process hole will be left at the position of the lower cylinder corresponding to the lower transverse flow channel, and the process hole will be sealed by a wire plug.

[0017] Furthermore, the air supply device adopts an air compressor, and the air supply port of the air compressor is connected to the air inlet.

[0018] The beneficial effect of adopting the above further scheme is that the air compressor can continuously fill air into the breaker hammer, and the filled air can be discharged through the gaps on the breaker hammer to form a cycle. Due to the air pressure, water cannot enter the hammer body of the breaker hammer, thereby solving the problem of water seepage prevention.

[0019] Furthermore, the drill rod is arranged in the lower cylinder of the shell through a bushing, and also includes a lubrication mechanism for lubricating the drill rod and the bushing. The lubrication mechanism includes a lubrication channel arranged in the shell and an oil supply lubrication device for supplying lubricating oil to the lubrication channel.

The position of the oil filling hole is convenient for connection and operation, and when the breaker is operating, if the oil filling hole is located on the water surface, the connection condition at the oil filling hole can also be observed.

[0021] Furthermore, the bushing includes an upper bushing and a lower bushing, and the lubrication passage includes a first oil supply passage for lubricating the drill rod and the upper bushing and a second oil supply passage for lubricating the drill rod and the lower bushing.

In order to ensure the standardization of the underwater operation of the breaker hammer and enable the breaker hammer to strike vertically during underwater operations, a top plate is provided on the top of the shell body and a vertical mark rod is installed. By observing the vertical state of the vertical mark rod, it can be judged whether the hammer is striking vertically and the state of the hammer can be adjusted in time.

[0025] Furthermore, the vertical pole is a ruler.

DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] like Figure 1 and Figure 2As shown in the figure, a breaker for underwater operations includes a housing, a drill rod 4 and a piston 5 that move within the housing. The drill rod 4 is located below the piston 5. It also includes a waterproof mechanism, which includes a waterproof passage provided within the housing and a gas supply device that can continuously supply gas to the waterproof passage of the breaker for underwater operations. A receiving cavity 6 for the movement of the drill rod 4 is provided within the housing. An air inlet hole 7 is provided at the upper part of the housing. The air inlet hole 7 is connected to the inlet of the waterproof passage, and the outlet of the waterproof passage is connected to the receiving cavity 6.

[0034] The housing includes an upper cylinder 1, a middle cylinder 2 and a lower cylinder 3. The receiving cavity 6 is provided within the lower cylinder 3, and the air inlet hole 7 is provided on the upper cylinder 1. The air inlet hole 7 is provided on the side of the upper cylinder 1. The gas supply device is connected to the air inlet hole 7 through a gas supply pipeline. In this way, the gas supply port of the gas supply pipeline is convenient to be connected to the air inlet hole 7. When the breaker is operating, if it is located above the water surface, the connection between the gas supply device and the air inlet hole 7 can also be observed.

[0035] The waterproof passage includes an upper flow passage provided within the upper cylinder 1, a middle flow passage 10 provided within the middle cylinder 2 and a lower flow passage provided within the lower cylinder 3. The upper flow passage is connected to the lower flow passage through the middle flow passage 10. In order to achieve the connection between the air inlet hole 7 and the receiving cavity 6, connected flow passages are respectively provided on the corresponding cylinders, so that the air provided by the gas supply device can lead into the receiving cavity 6, continuously supplying gas to the movement cavity of the drill rod 4 for underwater operations and avoiding the occurrence of water seepage.

[0036] The upper flow passage includes an upper horizontal flow passage 8 and an upper vertical flow passage 9. The air inlet hole 7 is connected to the inlet of the upper horizontal flow passage 8. The outlet of the upper horizontal flow passage 8 is connected to the inlet of the upper vertical flow passage 9, and the outlet of the upper vertical flow passage 9 is connected to the middle flow passage 10. Since the top of the upper cylinder 1 also needs to be connected to a quick connector, the air inlet hole 7 is provided on the side of the upper cylinder 1. Therefore, the upper horizontal flow passage 8 and the upper vertical flow passage 9 are provided. The air inlet hole 7 is connected to the gas supply device during underwater operations of the breaker. When underwater operations are not required and gas does not need to be introduced, a plug 21 can be used to seal this hole to prevent dust from entering the breaker and affecting the service life of the drill rod 4.

[0037] The lower flow passage includes a lower vertical flow passage 11 and a lower horizontal flow passage 12. The inlet of the lower vertical flow passage 11 is connected to the middle flow passage 10. The outlet of the lower vertical flow passage 11 is connected to the inlet of the lower horizontal flow passage 12, and the outlet of the lower horizontal flow passage 12 leads to the receiving cavity 6. In order to machine the lower horizontal flow passage 12, a process hole will be left at the position of the lower cylinder 3 corresponding to the lower horizontal flow passage 12, and this process hole will be sealed by a plug 21.

[0038] The air supply device adopts an air compressor, and the air supply port of the air compressor is connected to the air inlet 7. The air compressor can continuously fill air into the breaker, and the filled air can be discharged through the gap on the breaker to form a cycle. Due to the air pressure, water cannot enter the hammer body of the breaker, thereby solving the problem of water seepage prevention.

[0039] The drill rod 4 is arranged in the lower cylinder 3 of the housing through a bushing, and also includes a lubrication mechanism for lubricating the drill rod 4 and the bushing. The lubrication mechanism includes a lubrication channel arranged in the housing and an oil supply lubrication device for supplying lubricating oil to the lubrication channel. The oil filling hole 15 of the lubrication channel is arranged on the upper cylinder 1 of the housing, and the oil outlet of the lubrication channel leads to the bushing. In order to solve the problem of lubrication of the breaker during underwater operation, the lubrication structure is improved. The oil filling hole 15 is arranged in the upper part of the housing, specifically, on the side of the upper cylinder 1. The oil supply lubrication device is connected to the oil filling hole 15 through an oil supply pipeline to provide lubricating oil thereto. The position of the oil filling hole 15 is convenient for connection and operation. When the breaker is operating, if the oil filling hole 15 is located on the water surface, the position of the oil filling hole can also be observed, and the observation field is good.

[0040] There are also process holes in the lubrication channel, which can also be sealed by a plug. After the lubricating oil is filled, the oil filling hole 15 can be sealed by a plug.

[0041] The bushing includes an upper bushing 13 and a lower bushing 14, and the lubrication passage includes a first oil supply passage 16 for lubricating the drill rod 4 and the upper bushing 13, and a second oil supply passage 17 for lubricating the drill rod 4 and the lower bushing 14. The first oil supply passage 16 supplies oil for lubrication of the drill rod 4 and the upper bushing 13, and the second oil supply passage 17 supplies oil for lubrication of the drill rod 4 and the lower bushing 14, thereby solving the problem of lubrication of the drill rod 4 in the breaker.

[0042] like Figure 2 As shown, a vertical mark rod 19 is also included. A top plate 18 is provided on the top of the housing, and the vertical mark rod 19 is arranged on the top plate 18. During underwater operation, since the lower part or the middle and lower part of the hammer or the entire hammer is located underwater, it is impossible to confirm whether the breaker hammer is in a vertical state. In order to ensure the standardization of the underwater operation of the breaker hammer and enable the breaker hammer to strike vertically during underwater operation, a top plate 18 is provided on the top of the housing, and a vertical mark rod 19 is installed. By observing the vertical state of the vertical mark rod 19, it can be judged whether the hammer is striking vertically, and the hammer state can be adjusted in time.

[0043] The vertical reference rod 19 uses a scale. It can not only observe whether the vertical reference rod 19 is in a vertical state, but also observe the scale display on the scale. The length of the appropriate vertical reference rod 19 can be selected according to the working water depth, so that the breaker can confirm whether the breaker is in a vertical state through the vertical reference rod 19 during operation.

[0044] The vertical reference rod 19 is connected to the top plate 18 through a rod base 20. The connection between the rod base 20 and the top plate 18 ensures the installation stability of the vertical reference rod 19. The left or right side of the ejector rod extends out of the breaker area to ensure that the vertical reference rod 19 is obliquely above the top plate 18, avoiding interference with the connection between the top of the breaker and the quick coupler.

[0045] When the breaker needs to work underwater in the present utility model, the air supply device can continuously fill air into the breaker. The filled air can be discharged through the gaps on the breaker to form a cycle. Due to the air pressure, water cannot enter the body of the breaker, thus solving the problem of water seepage and rust during the operation of the breaker. When lubrication is required, the oil supply lubrication device supplies oil between the drill rod 4 and the bushing through the lubrication channel for lubrication. During operation, it is also possible to observe whether the breaker is in a vertical state and whether vertical impact is performed through the vertical reference rod 19. If the vertical reference rod 19 is observed to be tilted, the impact posture of the breaker can be adjusted in time, thus solving the problem of the standardization of the underwater operation of the breaker to make the body perform vertical impact and extending the service life of the breaker.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
