Description

Technical Field

[0001] This application relates to the field of rock drilling rig technology, specifically to an oil pipe rack for a rock drilling rig. Background Technology

[0002] A rock drilling rig is a type of rock drilling equipment used in tunnel and underground engineering projects employing the drill-and-blast method. It can move and support multiple rock drills to perform drilling operations simultaneously. Currently, during the operation of a rock drilling rig, the hydraulic hoses at the tail of the rock drill need to reciprocate along with the rock drill, and these hoses are supported by a hose support frame.

[0003] In the existing technology, when the oil pipe extends and retracts with the telescopic arm, the oil pipe is easily stretched or subjected to excessive tension when fully extended, and easily arches upward when fully retracted. This makes the oil pipe susceptible to various types of wear and compression, leading to oil pipe damage, reduced service life, and affecting equipment use.

[0004] Therefore, the structure of the tubing rack in the existing technology has room for further improvement. Utility Model Content

[0005] In view of this, and in response to the technical problem that oil pipes are easily squeezed or arched when fully extended or retracted in the prior art, leading to damage to the oil pipes and reducing their service life, this application provides an oil pipe bracket for a rock drilling rig. By changing the distance and spacing between two adjacent brackets, it effectively prevents the oil pipes from being squeezed or worn during operation, thereby improving the durability and service life of the oil pipes.

[0006] To achieve the above objectives, this application provides the following technical solution: a hydraulic hose support for a rock drilling rig, comprising:

[0007] Pipe racks, which are slidably connected to the trolley drill arm, and there are at least three pipe racks;

[0008] Oil pipe, which is mounted on the pipe rack;

[0009] The oil pipe has an extended state and a retracted state. In the fully extended state, the distance between two adjacent pipe supports is less than the length of the oil pipe between the two adjacent pipe supports.

[0010] Compared with the prior art, the tubing support of this application has the tubing in both an extended and retracted state. The distance between two adjacent tubing supports is less than the length of the tubing between the two adjacent supports. This can effectively prevent the tubing from being stretched or subjected to excessive tension during the extension process, and also prevent the tubing from arching upwards during the retraction process. This avoids wear caused by excessive stretching or arching, thereby reducing the risk of tubing damage, extending the service life of the tubing, improving the efficiency of tubing use, and enhancing the flexibility and convenience of operation.

[0011] Furthermore, the distance between two adjacent pipe supports is less than the length of the oil pipe between two adjacent pipe supports, with the difference ranging from 15 to 25 cm.

[0012] In some embodiments of this application, the tube rack is divided into a front tube rack, a middle tube rack, and a rear tube rack, all of which are connected to the trolley drill arm. The middle tube rack is located between the front tube rack and the rear tube rack.

[0013] Furthermore, the trolley drill arm includes a basic arm and a telescopic arm, with the basic arm and the telescopic arm being slidably connected.

[0014] The front tube frame is connected to the basic arm, the middle tube frame is slidably connected to the basic arm, and the rear tube frame is connected to the telescopic arm.

[0015] The telescopic arm can drive the rear tube frame to move back and forth.

[0016] Furthermore, the basic arm is provided with a slide, and the intermediate tube frame is connected to the basic arm through the slide, with the tube frame sleeved on the slide;

[0017] The carriage is detachably connected to the basic arm, and the carriage has a U-shaped structure.

[0018] Furthermore, the intermediate tube rack includes a hook and a binding assembly, the hook being connected to the binding assembly and sleeved on the carriage, and the binding assembly being used to secure the oil pipe.

[0019] Furthermore, the binding assembly includes a support frame and a binding member, the support frame is connected to the binding member, the oil pipe is sleeved on the binding member, and the binding member is located in the middle of the support frame;

[0020] The support frame is connected to the hook. The support frame has a U-shaped structure and is used to support the oil pipe.

[0021] Furthermore, the rear tube rack includes a connecting tube and a tube clamp; one side of the connecting tube is connected to the tube clamp, and the other side is connected to the telescopic arm, and the connecting tube can move back and forth with the telescopic arm;

[0022] The pipe clamps are at least two in number, and the two pipe clamps are located at both ends of the connecting pipe. The pipe clamps are used to install the oil pipe, and the pipe clamps and the support frame are on the same straight line.

[0023] Furthermore, the rear tube frame also includes a connecting assembly, the connecting tube being connected to the telescopic arm via the connecting assembly, the connecting assembly being disposed at the end of the telescopic arm away from the base arm;

[0024] There are two connecting components, which are spaced apart, and the connecting components are detachably connected to the telescopic arm.

[0025] Furthermore, there is a certain distance between the connecting pipe and the telescopic arm, and when the oil pipe is in the retracted state, the connecting pipe is located below the slide.

[0026] The hydraulic hose support for a rock drilling rig disclosed in this application has at least the following technical advantages:

[0027] 1. By setting up a slide, the tube rack is connected to the basic arm through the slide. The tube rack is fitted onto the slide. It can be understood that the intermediate tube rack can slide on the slide. The support frame and the basic arm are detachably connected. When the slide needs to be maintained or replaced, it can be replaced conveniently and quickly. The slide can also provide stable support for the intermediate tube rack.

[0028] 2. By setting up front and rear pipe supports, the telescopic boom can drive the rear pipe support to move back and forth, allowing the pipe support to flexibly adjust the length and position of the oil pipe according to actual needs, adapting to different working environments and requirements. The cooperation between the front and rear pipe supports enhances the overall structural stability of the pipe support, making it less likely for the oil pipe to shift or tilt during operation, thus ensuring the safety and reliability of the operation.

[0029] 3. By setting a connecting pipe, when the oil pipe is in the retracted state, the connecting pipe is located below the carriage, and there is a certain distance between the connecting pipe and the carriage, and a certain distance between the connecting pipe and the base arm. By setting the distance, the direct contact between the connecting pipe and the carriage and the base arm can be reduced during use, thereby reducing friction and wear, and can also effectively avoid prolonging jamming and increase the service life of the carriage and the connecting pipe.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0042] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 4 illustrate.

[0043] This embodiment provides a hydraulic hose support for a rock drilling rig, which is applied in the field of rock drilling rig technology. Specifically, as shown in... Figures 1 to 4As shown, the system includes an oil pipe 2 and a pipe support 1. The pipe support 1 is slidably connected to the drill arm of the trolley. There are at least three pipe supports 1. The oil pipe 2 is installed on the pipe support 1. The pipe support 1 is located on the side of the drill arm of the trolley. The pipe support 1 is used to support the oil pipe 2, which can effectively prevent the oil pipe 2 from tilting or shifting during use, thus improving the flexibility of the equipment. In this embodiment, the oil pipe 2 has an extended state and a retracted state. In the fully extended state, the distance between two adjacent pipe supports 1 is less than the length of the oil pipe 2 between two adjacent pipe supports 1, with a difference ranging from 15 to 25 cm. This can effectively prevent the oil pipe 2 from being stretched or subjected to excessive tension during the extension process, and can also prevent the oil pipe 2 from arching upwards during the retraction process, avoiding wear caused by excessive stretching or arching, thereby reducing the risk of damage to the oil pipe 2, extending the service life of the oil pipe 2, improving the efficiency of the oil pipe 2, and improving the flexibility and convenience of operation.

[0044] Specifically, such as Figure 2 As shown, the pipe rack 1 is divided into a front pipe rack 11, an intermediate pipe rack 12, and a rear pipe rack 13. The front pipe rack 11, intermediate pipe rack 12, and rear pipe rack 13 are all connected to the trolley drilling arm. The intermediate pipe rack 12 is located between the front pipe rack 11 and the rear pipe rack 13. There is at least one front pipe rack 11, at least one intermediate pipe rack 12, and two rear pipe racks 13. The front pipe rack 11 is detachably connected to the basic arm 3 by bolts, which facilitates replacement and maintenance. The rear pipe rack 13 is connected to the telescopic arm 4. The telescopic arm 4 can drive the rear pipe rack 13 to move back and forth. The cooperation between the front pipe rack 11 and the rear pipe rack 13 enhances the overall structural stability of the pipe rack 1, making it less likely for the oil pipe 2 to shift or tilt during operation, thus ensuring the safety and reliability of the operation.

[0045] Furthermore, such as Figure 2 As shown, the trolley drilling arm includes a basic arm 3 and a telescopic arm 4. The basic arm 3 and the telescopic arm 4 are slidably connected. The front pipe support 11 is connected to the basic arm 3, and the intermediate pipe support 12 is slidably connected to the basic arm 3. The intermediate pipe support 12 can move relative to the basic arm 3 to realize the expansion or contraction of the oil pipe 2. The rear pipe support 13 is connected to the telescopic arm 4. The telescopic arm 4 can drive the rear pipe support 13 to move back and forth. When the telescopic arm 4 extends, it drives the oil pipe 2 to move forward. When the oil pipe 2 extends to a certain length, it will pull the intermediate pipe support 12 to move accordingly, thereby realizing the expansion of the oil pipe 2. When the telescopic arm 4 retracts, it drives the oil pipe 2 to move backward. When the oil pipe 2 retracts to a certain length, it will push the intermediate pipe support 12 to move accordingly, thereby realizing the contraction of the oil pipe 2. This effectively prevents damage to the oil pipe 2 when the telescopic arm 4 extends or retracts, and extends the service life of the oil pipe 2.

[0046] like Figures 2 to 4As shown, the basic arm 3 is equipped with a slide 5, which has a U-shaped structure and a smooth surface. The intermediate tube frame 12 is connected to the basic arm 3 through the slide 5. The intermediate tube frame 12 is fitted onto the slide 5, which means that the intermediate tube frame 12 can slide on the slide 5. The slide 5 and the basic arm 3 are detachably connected. When the slide 5 needs to be maintained or replaced, it can be replaced conveniently and quickly. The slide 5 can also provide stable support for the intermediate tube frame 12.

[0047] Furthermore, such as Figure 3 As shown, the intermediate pipe rack 12 includes a hook 121 and a binding assembly 122. The hook 121 is connected to the binding assembly 122 and is sleeved on the slide 5. The hook 121 can slide relative to the slide 5. The binding assembly 122 is used to install the oil pipe 2, effectively preventing the oil pipe 2 from tilting or shifting, fixing the oil pipe 2, and the oil pipe 2 can move relative to the binding assembly 122, improving the flexibility and operating efficiency of the oil pipe 2. The binding assembly 122 includes a support frame 1221 and a binding member 1222. The support frame 1221 has a U-shaped structure, and the binding member 1222 is a spring ratchet strap winch. The support frame 1221 is connected to the binding member 1222, and the oil pipe 2 is sleeved with the binding member 1222. The binding member 1222 is located in the middle of the support frame 1221 to ensure its stability. One end of the support frame 1221 near the basic arm 3 is connected to the hook 121. The support frame 1221 is used to support the oil pipe 2. The support frame 1221 has openings on one side and at the bottom, and the positions of the openings correspond to the positions of the binding member 1222. The binding member 1222 is at least partially located below the support frame 1221. The binding member 1222 passes through the opening of the support frame 1221 to fix the oil pipe 2, which helps to reduce the friction between the oil pipe 2 and the binding member 1222 and reduce the wear on the oil pipe 2.

[0048] Furthermore, such as Figure 2As shown, the rear tube support 13 includes a connecting pipe 131 and a pipe clamp 132. One side of the connecting pipe 131 is fixedly connected to the pipe clamp 132, and the other side of the connecting pipe 131 is at least partially connected to the telescopic arm 4. The connecting pipe 131 is located at the end of the telescopic arm 4 away from the base arm 3. The telescopic arm 4 can drive the connecting pipe 131 to move back and forth. There are at least two pipe clamps 132, located at both ends of the connecting pipe 131. The pipe clamps 132 are used to install the oil pipe 2. The front tube support 11 and the pipe clamps 132 are also equipped with spring ratchet strap winches. The oil pipe 2 is fixed by the spring strap winches, which can ensure the stability of the oil pipe 2 and prevent the oil pipe 2 from tilting or displacing. The pipe clamp 132 and the support frame 1221 are on the same straight line, which can effectively prevent the oil pipe 2 from being stretched or subjected to excessive tension during the deployment process. When the oil pipe 2 is in the retracted state, the connecting pipe 131 is at least partially located below the carriage 5. There is a certain distance between the connecting pipe 131 and the carriage 5, and a certain distance between the connecting pipe 131 and the base arm 3. By setting the distance, the direct contact between the connecting pipe 131 and the carriage 5 and the base arm 3 can be reduced during use, thereby reducing friction and wear. It can also effectively prevent jamming and extend the service life of the carriage 5 and the connecting pipe 131.

[0049] Furthermore, such as Figure 4 As shown, the rear tube frame 13 also includes a connecting component 133. The connecting tube 131 is connected to the telescopic arm 4 through the connecting component 133. The connecting component 133 is located at the end of the telescopic arm 4 away from the base arm 3. There are two connecting components 133, which are spaced apart. The connecting component 133 is detachably connected to the telescopic arm 4. When it is necessary to replace or maintain the connecting tube 131, it can be done by disassembling and assembling the connecting component 133. The connecting component 133 includes a support plate 1331 and a connecting plate 1332. The support plate 1331 and the connecting plate 1332 are fixedly connected. The support plate 1331 is connected to the telescopic arm 4 by bolts. There are two sets of bolts, which are symmetrically arranged along the center line of the support plate 1331. The bolts are installed on the edge of the support plate 1331. The end of the connecting plate 1332 away from the support plate 1331 is fixedly connected to the connecting pipe 131. There are at least two connecting plates 1332. The connecting plates 1332 have a V-shaped structure. The two connecting plates 1332 are symmetrically arranged along the center line of the support plate 1331. The connecting plates 1332 are located between the two sets of bolts, which enhances the connection strength between the connecting pipe 131 and the connecting plate 1332 and improves the stability of the connecting pipe 131.

[0050] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
