[0054] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present invention. Rather, they are merely examples of devices and apparatuses consistent with certain aspects of the present invention, as detailed in the appended claims.

[0055] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not limit their order. Those skilled in the art will understand that terms such as "first" and "second" do not limit the number or execution order, and do not necessarily imply differences.

[0056] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In the embodiments of the present application, "at least one" refers to one or more, and "a plurality" refers to two or more.

[0057] It should be noted that the phrase "at the time of..." in the embodiments of this application can refer to the instantaneous occurrence of a certain event or a period of time after the occurrence of the certain event, and this is not specifically limited in this embodiment of the application. Furthermore, the oil pipe securing device provided in the embodiments of this application is merely an example, and the oil pipe securing device may include more or less aspects.

[0058] At present, rock drilling equipment is widely used in the mining field, and the working conditions of mining equipment are more complex and harsh. The rock drilling rig mainly consists of a frame, power unit, operating table, working device, rock drill, travel mechanism and other accessories.

[0059] The main processes of a rock drill rig operation include positioning, pushing, and impacting the drill. When the rock drill is operating, the drill boom must first be positioned. When the boom cylinder is actuated, the boom rotates 360 degrees. The oil pipes fixed to the boom rotate with the boom, causing them to become entangled and pulled, often causing wear.

[0060] At the same time, during the impact of the rock drill and the extension and retraction of the boom, the boom is in a shaking state, and the hose in the pipe clamp has no protection, which can easily cause pipeline wear and oil leakage.

[0061] In summary, in the prior art, the oil pipes of rock drilling equipment have a high degree of wear and a short service life.

[0062] Based on this, embodiments of the present application provide an oil pipe securing device and rock drilling equipment, wherein the oil pipe securing device is used in rock drilling equipment. Because the oil pipe in the prior art rotates with the boom, it is prone to entanglement and pulling during rotation, causing wear. To reduce this wear, embodiments of the present application utilize a locking structure and a position-limiting member to secure the oil pipe to the support member. To accommodate oil pipes of varying diameters, the locking structure and position-limiting member can adjust the size of the space within which the oil pipe is secured.

[0063] The invention can be used in the field of fixed frame technology, and aims to solve the above technical problems of the prior art.

[0064] Figure 1 A front view of the oil pipe fixing device provided in an embodiment of the present application; Figure 2 A side view of the oil pipe fixing device provided in an embodiment of the present application; Figure 3 A top view of the oil pipe fixing device provided in an embodiment of the present application.

[0065] like Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides an oil pipe fixing device for rock drilling equipment, comprising a mounting member 100, a support member 200, a limiting member 300 and a locking mechanism 400;

[0066] The support member 200 is fixedly connected to the mounting member 100, and the locking mechanism 400 is fixedly connected to the support member 200;

[0067] The support member 200 is provided with a first accommodation space 210, and the first accommodation space 210 is used for pipe routing;

[0068] One end of the limiting member 300 is fixedly connected to the locking mechanism 400, and the other end of the limiting member 300 passes through the first accommodation space 210 of the support member 200 and is connected to the locking mechanism 400;

[0069] The locking mechanism 400 is used to lock the oil pipe in the first accommodating space 210 after the oil pipe is arranged in the first accommodating space.

[0070] For example, the rock drilling equipment may be a rock drilling rig, a deep hole drill, or other rock drilling equipment that requires a fixed oil pipe. The following description will be made using a rock drilling rig as an example.

[0071] Exemplarily, the support member 200 and the mounting member 100 can be fixedly connected by welding, threaded connection, riveting, etc. Preferably, the support member 200 and the mounting member 100 can be fixedly connected by welding, which is simple and easy.

[0072] For example, the locking mechanism 400 and the support member 200 may be directly fixedly connected by welding, threaded connection, riveting, etc., or may be indirectly connected by other components.

[0073] For example, bolt holes can be provided on the mounting member 100, which is connected to the arm through bolts and assembled on the arm to fix the oil pipe. The number of bolt holes is selected as needed. Preferably, four bolt holes can be provided, which has a simple and stable structure.

[0074] Specifically, the first accommodating space 210 can accommodate one or more oil pipes, and the length of the limiter 300 can be adjusted according to actual conditions to ensure that the oil pipe is fixed in the first accommodating space 210. After the length of the limiter 300 is adjusted, the locking mechanism 400 fixes the limiter 300 to ensure that the length of the limiter 300 does not change.

[0075] The oil pipe is fixed by the support member 200, the limit member 300 and the locking mechanism 400, and is assembled on the boom through the mounting member 100, thereby avoiding entanglement and pulling of the oil pipe when the boom moves, reducing wear of the oil pipe and increasing the service life of the oil pipe.

[0076] In some embodiments, the locking mechanism 400 includes a locked state and an open state;

[0077] When the locking mechanism 400 is in the locked state, the limiting member 300 is fixedly connected to the locking mechanism 400;

[0078] When the locking mechanism 400 is in the open state, the limiting member 300 is movably connected to the locking mechanism 400 .

[0079] Specifically, when the locking mechanism 400 is in the locked state, the limiting member 300 is fixedly connected to the locking mechanism 400 to ensure that the length of the limiting member 300 does not change, so as to lock the oil pipe in the first accommodating space 210 .

[0080] When the locking mechanism 400 is in the open state, the limiting member 300 is movably connected to the locking mechanism 400 , and the length of the limiting member 300 can be adjusted according to actual conditions to facilitate the addition or removal of the oil pipe in the first accommodating space 210 .

[0081] Through the locking mechanism 400, the length of the limiter 300 can be adjusted according to the number and diameter of the oil pipes, and the length of the limiter 300 can be ensured to remain unchanged so as to fix the oil pipes. For oil pipes with different outer diameters on the boom, only one oil pipe fixing device is required, and there is no need to prepare multiple types of pipe clamps, which reduces equipment costs and the difficulty of management and maintenance, and has strong adaptability.

[0082] In some embodiments, the locking mechanism 400 includes a locking bracket 410 , a first locking member 420 , and a second locking member 430 ;

[0083] The locking bracket 410 includes two oppositely disposed first vertical plates 411 and second vertical plates 412 , and a second accommodation space 413 is provided between the first vertical plates 411 and the second vertical plates 412 ;

[0084] The first locking member 420 is disposed between the first vertical plate 411 and the second vertical plate 412 and is rotatably connected to the first vertical plate 411 and the second vertical plate 412. The first locking member 420 is used to surround the limiting member 300 and adjust the length of the limiting member 300 in the first accommodating space 210 by rotating the first locking member 420.

[0085] At least one end of the first locking member 420 is exposed on the first vertical plate 411 or the second vertical plate 412, and at least one end of the first locking member 420 is provided with a locking buckle 421, which includes a plurality of locking grooves spaced apart along the circumference of the locking member;

[0086] The second locking member 430 is provided with a locking portion 432 that cooperates with the locking groove. When the locking portion 432 is located in the locking groove, the second locking member 430 is locked and connected with the first locking member 420, and the locking mechanism 400 is in a locked state.

[0087] For example, both ends of the first locking member 420 are exposed from the locking bracket 410 , and both ends of the first locking member 420 are provided with locking buckles 421 , so that the locking state of the locking mechanism 400 is more stable.

[0088] For example, the first locking member 420 may be a cylindrical shaft, and a hexagonal component may be fixed at one or both ends of the first locking member 420 to facilitate rotating the first locking member 420 with a hexagonal wrench to adjust the length of the limiting member 300 in the first accommodating space 210.

[0089] Specifically, the stopper 300 is mounted around the first locking member 420. Rotating the first locking member 420 adjusts the length of the stopper 300 within the first accommodating space 210, thereby securing oil pipes of varying numbers and diameters within the first accommodating space 210. When the locking portion 432 is located within the locking groove, the second locking member 430 is locked to the first locking member 420, and the locking mechanism 400 is locked. The first locking member 420 cannot rotate, ensuring that the length of the stopper 300 does not change.

[0090] By providing a locking buckle 421 on the first locking member 420 and a locking portion 432 on the second locking member 430, the locking mechanism 400 is locked and can be adjusted at any time according to different pipe diameters. The operation is simple and easy to implement.

[0091] In some embodiments, the second locking member 430 includes a connecting rod 431 , a locking portion 432 , and a clip 433 ;

[0092] The connecting rod 431 is provided through the first vertical plate 411 and the second vertical plate 412 and is rotatably connected to the first vertical plate 411 and the second vertical plate 412, and both ends of the connecting rod 431 are exposed outside the first vertical plate 411 and the second vertical plate 412;

[0093] The locking portion 432 is connected to the connecting rod 431 from the outside of the first vertical plate 411 and the second vertical plate 412, and the locking portion 432 is engaged with the locking groove;

[0094] A clamping spring 433 is sleeved on the connecting rod 431 , one end of the clamping spring 433 is engaged with one of the first vertical plate 411 and the second vertical plate 412 , and the other end of the clamping spring 433 is engaged with the locking portion 432 ;

[0095] When the locking portion 432 moves along the contraction direction of the clamping spring 433 , the locking portion 432 disengages from the locking groove, the first locking member 420 and the second locking member 430 are disconnected, and the locking mechanism 400 is in an open state.

[0096] Specifically, the retaining spring 433 is mounted on the connecting rod 431, with one end engaging the first upright plate 411 or the second upright plate 412 and the other end engaging the locking portion 432. This supports the locking portion 432, ensuring that the locking portion 432 is engaged with the locking groove, thereby locking the second locking member 430 with the first locking member 420. By moving the locking portion 432 in the direction of contraction of the retaining spring 433, the locking portion 432 is disengaged from the locking groove, disconnecting the first locking member 420 from the second locking member 430. The first locking member 420 can then be rotated to adjust the length of the stopper 300.

[0097] The locking portion 432 is supported by the clamping spring 433 so that the locking mechanism 400 includes a locked state and an open state, which has a simple structure and is easy to operate.

[0098] In some embodiments, the locking buckle 421 is a ratchet structure.

[0099] The ratchet structure has an anti-reverse function, ensuring that the first locking member 420 is stationary in the locked state, and has high reliability.

[0100] In some embodiments, the mounting member 100 and the locking mechanism 400 are relatively arranged on both sides of the support member 200 along a first direction, wherein the first direction is perpendicular to the pipe running direction in the first accommodating space 210 .

[0101] In some embodiments, a partition 500 is further included;

[0102] The partition 500 is fixedly connected to the support member 200;

[0103] The partition plate 500 is provided with at least one hanging position, which is used to hang the impact tube.

[0104] For example, a through hole may be provided on the partition 500 as a hanging position, and the impact tube may be hung by a cable tie or other means.

[0105] Specifically, the impact tube is a component in the rock drilling equipment used to transmit impact energy. The impact tube is arranged separately through the partition 500 to reduce the friction between the impact tube and the oil pipe, avoid vibration of the pipeline during operation, and have high stability.

[0106] For example, the partition 500 and the support member 200 can be fixedly connected by welding, threading, riveting, or other connection methods.

[0107] For example, a through hole can be set at the bottom of the second accommodating space 413 of the locking mechanism 400, and a through hole can be set on the partition 500. The locking mechanism 400 and the partition 500 are connected by bolts, and then the partition 500 is welded to the support member 200 to realize the connection between the support member 200, the locking mechanism 400 and the partition 500.

[0108] In some embodiments, the limiting member 300 is a molded cable tie.

[0109] For example, the formed cable tie may be a cloth tape, which is convenient for being wound around the first locking member 420 and reducing wear on the oil pipe.

[0110] In some embodiments, the support member 200 comprises a plurality of interconnected round steel bars.

[0111] Specifically, the support member 200 includes a first round steel and at least one second round steel. The two parts of the first round steel are arranged in parallel to form a first accommodating space 210. The second round steel is fixedly connected to the two parts arranged parallel to the first round steel to enhance the stability of the support member 200.

[0112] At the same time, the support member 200 made of round steel can effectively reduce the friction and impact of the oil pipe during operation and extend the service life of the oil pipe.

[0113] For example, two second round steels may be provided, one at the bottom of the first accommodating space 210 and the other at the side of the first accommodating space 210 close to the mounting member 100 , achieving a balance between the number of second round steels and the stability of the support member 200 .

[0114] In a second aspect, the present application provides a rock drilling device, comprising an action boom and any one of the oil pipe fixing devices provided in the first aspect, wherein the oil pipe fixing device is fixedly connected to the action boom.

[0115] The specific structure and working mode of the oil pipe fixing device are described in detail in the above embodiments and will not be repeated here.

[0116] This device has the following technical effects:

[0117] By adjusting the formed cable ties to fix different oil pipes, it can adapt to oil pipes of different diameters. There is no need to prepare multiple types of pipe clamps, which reduces equipment costs and the difficulty of management and maintenance, and has strong adaptability.

[0118] The inner edges of the oil pipe fixing devices are all made of round steel, which can effectively reduce the friction and impact of the oil pipe during operation, extend the service life of the oil pipe, and provide good protection effect.

[0119] By arranging the impact tube separately, the friction between the impact tube and the oil pipe can be reduced, and the oil pipe can be prevented from vibrating during operation, thereby achieving high stability.

[0120] So far, the technical solutions of the embodiments of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the scope of protection of the present application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
