Description

Technical Field

[0001] This application relates to the field of rock drilling rig technology, and in particular to an oil pipe bracket for a rock drilling rig. Background Technology

[0002] A rock drilling rig is a common piece of equipment used in tunnel boring and mining. It typically features a propulsion cylinder and a collision valve block, with oil pipes connected to these components for oil supply. To ensure neater pipe installation, a pipe bracket is usually installed on the rig. Currently, the bottom of the pipe bracket usually has two clamps, used to secure the oil pipes for the propulsion cylinder and the collision valve block, respectively. A common installation method involves a pipe bracket connecting plate with six staggered bolt holes, which are then bolted to the propulsion beam. However, using clamps to fix the tubing has some drawbacks. To ensure the tubing doesn't shift, the clamps apply significant pressure, which can not only wear down the tubing surface but also potentially damage it. Furthermore, the distance between the tubing bracket and the thrust beam means the bracket can easily scrape against the rock wall during drilling, causing bolts to break under stress. Some bolts may even become lodged in the threaded holes of the bracket's connecting plate, making them difficult to remove. Therefore, a tubing bracket that can protect the tubing is urgently needed. Utility Model Content

[0003] One objective of this application is to provide a hydraulic hose bracket for a rock drilling rig that can solve at least one of the defects in the aforementioned background art.

[0004] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a hydraulic hose bracket for a rock drilling rig, comprising a bracket body and a beam, wherein the bracket is provided with at least one mounting arm, the beam body has an internal cavity, the side wall of the beam body has a through hole, the mounting arm has a mounting hole aligned with the through hole, an internal threaded seat is installed in the cavity, and a bolt is installed in the mounting hole, the bolt passing through the side wall of the mounting arm and the beam body in sequence and being fixedly connected to the internal threaded seat; the bracket is provided with a connecting part, the connecting part having at least one channel communicating with the outside, one end of the channel having a first interface, and the other end having a second interface.

[0005] With the above setup, the original oil pipe can be divided into two sections using the first and second interfaces. One section is connected to the first interface, and the other is connected to the second interface. The section of oil pipe below the connection is a fixed structure and will not be pulled, which can further improve the safety of the oil pipe. If either section of the oil pipe is damaged, it can be replaced separately, which effectively reduces the maintenance cost of the oil pipe. The internal thread seat is located inside the beam, and the bracket is fixedly installed on the side wall of the beam, which can further save space and prevent the bracket from colliding with the rock wall during equipment operation.

[0006] Preferably, the internal threaded seat is provided with a boss that extends into the through hole, and the bolt is inserted into the boss. The boss has a threaded structure inside that mates with the bolt. This design effectively improves the installation stability of the internal threaded seat and prevents the bracket from shaking.

[0007] Preferably, the boss passes through the perforation and protrudes from the side wall of the beam. A pad is installed on the boss, with one side of the pad fitting against the beam and the other side fitting against the mounting arm. The pad prevents the mounting arm from directly contacting the beam. When the bolts are tightened, the pad acts as a buffer and protector, preventing deformation and wear on the mating surfaces of the beam and the mounting base.

[0008] Preferably, there are two mounting arms, symmetrically arranged on both sides of the connecting portion, and each mounting arm has multiple mounting holes. This arrangement further improves the installation stability of the bracket and prevents the bracket's position from shifting during long-term operation.

[0009] Preferably, there are multiple channels, and these channels are not interconnected. Both the first and second interfaces are equipped with connection structures that mate with the oil pipes. This configuration increases the number of oil pipes that can be installed, and users can also adjust the number of channels according to actual needs to ensure that multiple oil pipes can be secured using a single bracket.

[0010] Preferably, the connection structure includes a threaded connection, with internal threads on the inner walls of the first and second interfaces and external threads on the outer wall of the oil pipe. This design further reduces the difficulty of oil pipe installation; when the oil pipe needs to be replaced, installation and disassembly can be quickly completed simply by tightening the oil pipe.

[0011] Preferably, the internal threaded seat is made of alloy structural steel. This design further improves the structural strength of the internal threaded seat, making the bracket installation more stable.

[0012] Preferably, a mounting beam is vertically arranged on the connecting part, and a protective component is mounted on the mounting beam. This arrangement allows the bracket to be protected by the protective component, preventing damage to the bracket's mounting structure from gravel.

[0013] Preferably, the connecting portion is further provided with a support block for supporting the mounting beam. This arrangement can further improve the stability of the mounting beam and prevent it from bending under external impact.

[0014] Preferably, the protective component includes an L-shaped baffle, which is fixedly installed to the mounting beam by fasteners. This configuration allows for simultaneous protection of the upper and side parts of the bracket via the baffle, and the baffle can be quickly replaced by unscrewing the fasteners when it wears out.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: The first and second interfaces can divide the original oil pipe into two sections, one of which is connected to the first interface and the other to the second interface. The section of oil pipe below the connection is a fixed structure and will not be pulled, which can further improve the safety of the oil pipe. If either section of the oil pipe is damaged, it can be replaced separately, which effectively reduces the maintenance cost of the oil pipe. The internal thread seat is located inside the beam and the bracket is fixedly installed on the side wall of the beam, which can further save space and avoid the bracket from colliding with the rock wall during equipment operation.

[0016] A pad is installed between the beam and the mounting arm, serving as a buffer and protector to prevent deformation and wear on the mating surfaces of the beam and the mounting base. The first and second interfaces are connected to the oil pipe via threads; when the oil pipe needs replacement, simply unscrewing the pipe allows for quick installation and removal. A baffle protects the upper and sides of the bracket, preventing damage to the bracket's mounting structure from falling debris. This invention offers advantages such as high safety and long service life. Attached Figure Description

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, 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, and should not be construed as limiting the specific protection scope of this application.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] One aspect of this application provides a hose support for a rock drilling rig, one preferred embodiment of which is, for example... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a bracket 100 body and a beam 101. The bracket 100 has a mounting arm 1. The beam 101 has an internal cavity and a through hole on its side wall. The mounting arm 1 has a mounting hole 11 aligned with the through hole. An internally threaded seat 3 is installed inside the cavity, and a bolt 200 is installed in the mounting hole 11. During installation, the bolt 200 passes through the mounting arm 1 and the side wall of the beam 101 in sequence and is fixedly connected to the internally threaded seat 3. The bracket 100 also has a connecting part 2, which has a channel communicating with the outside. One end of the channel has a first interface 21, and the other end has a second interface 22. The first interface 21 and the second interface 22 are used to install oil pipes (not shown in the figure). When two sections of oil pipe are installed at the first interface 21 and the second interface 22 respectively, oil in either section of oil pipe can be transported to the other section of oil pipe through the channel.

[0026] It should be understood that in the prior art, the bracket 100 typically fixes the oil pipe using clamps. To prevent the oil pipe from shifting, high pressure needs to be applied to it. When the pressure applied by the clamps is too high, it can not only damage the surface of the oil pipe but also tear it. In addition, the current bracket 100 is a certain distance from the beam 101, making it easy for the bracket 100 to snag on the rock wall during propulsion, leading to wear and tear.

[0027] The bracket 100 in this application is fixedly installed on the side wall of the beam 101, and the internal thread seat 3 is installed inside the beam 101, which can further save space and prevent the bracket 100 from colliding with the rock wall during equipment operation. In addition, the first interface 21 and the second interface 22 can divide the original oil pipe into two sections, one section of the oil pipe is connected to the first interface 21, and the other section of the oil pipe is connected to the second interface 22. The section of the oil pipe below the connecting part 2 is a fixed structure and will not be pulled, which can further improve the safety of the oil pipe. When either section of the oil pipe is damaged, it can be replaced separately, effectively reducing the maintenance cost of the oil pipe.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the internal thread seat 3 is provided with a boss 31, which extends into the through hole and engages with the bolt 200 on the mounting arm 1. The boss 31 has an internal threaded structure that mates with the bolt 200. When installing the bracket 100, first align the mounting hole 11 with the through hole, then insert the bolt 200 into the boss 31 and rotate it to fix the bracket 100 to the side of the beam 101. The boss 31 further improves the installation speed of the internal thread seat 3; the user only needs to insert the boss 31 into the through hole to quickly install the internal thread seat 3 to the designated position.

[0029] Furthermore, such as Figure 1 and Figure 3 As shown, the boss 31 passes through the perforation and protrudes from the side wall of the beam 101. A pad 300 is installed on the boss 31. One side of the pad 300 is in contact with the beam 101, and the other side is in contact with the mounting arm 1. When the bracket 100 is fixedly connected to the beam 101, the pad 300 is located between the mounting arm 1 and the beam 101, which can prevent the mounting arm 1 from directly contacting the beam 101. When the bolt 200 is tightened, the pad 300 can play a buffering and protective role, preventing deformation and wear of the mating surfaces of the beam 101 and the mounting seat.

[0030] In this embodiment, as Figure 1As shown, there are two mounting arms 1, symmetrically arranged on both sides of the connecting part 2. Each mounting arm 1 has multiple mounting holes 11, which can be fitted with multiple bolts 200 to ensure a more secure installation. The mounting arms 1 on both sides work together to provide more stable support for the bracket 100, preventing the bracket 100 from shifting its position during long-term operation and thus affecting its support effect on the oil pipe.

[0031] It is understandable that the number of mounting arms 1 can be adjusted by those skilled in the art according to actual needs. Although the more mounting arms 1 there are, the more stable the bracket 100 will be, it is also necessary to consider that the additional mounting arms 1 may occupy the space of the beam 101, increase the overall weight of the bracket 100 and increase the manufacturing cost.

[0032] In addition, in order to further improve the installation stability of bolt 200, the material of internal thread seat 3 in this application includes alloy structural steel, and the alloy structural steel is heat treated to improve the structural strength of internal thread seat 3, so as to make the installation of bracket 100 more stable; after heat treatment, alloy structural steel can significantly improve toughness and plasticity while maintaining high strength, thus making internal thread seat 3 more durable.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, there are multiple channels, and these channels are not interconnected. Both the first interface 21 and the second interface 22 are equipped with connection structures for use with oil pipes. Multiple oil pipes are simultaneously fixed by a bracket 100. During installation, simply align the two sections of oil pipe with the first interface 21 and the second interface 22 respectively, and then secure them using the connection structures. The specific number of channels can be adjusted by those skilled in the art according to their needs.

[0034] Furthermore, the connection structure includes, but is not limited to, threaded connections, interference fits, and snap-fit ​​connections. Here, we will take a threaded connection as an example for specific explanation. The inner walls of the first interface 21 and the second interface 22 are provided with internal threads, and the outer wall of the oil pipe is provided with external threads. Threaded connections not only reduce the difficulty of oil pipe installation but also improve the connection stability between the oil pipe and the first interface 21 or the second interface 22. When the oil pipe needs to be replaced, installation and removal can be quickly completed simply by tightening the oil pipe.

[0035] It should be noted that the oil stored in the oil pipe is a liquid, and there is a risk of leakage when the oil passes through the first interface 21 and the second interface 22. Therefore, in order to avoid oil leakage in the oil pipe, sealing elements should be installed in the first interface 21 and the second interface 22 for sealing.

[0036] In this embodiment, as Figure 1As shown, a mounting beam 4 is vertically arranged on the connecting part 2, and a protective component is installed on the mounting beam 4. The protective component can protect the bracket 100 to prevent debris on the rock wall from damaging the mounting structure of the bracket 100. Furthermore, a support block 41 is provided on the connecting part 2 to support the mounting beam 4. By supporting the side of the mounting beam 4 with the support block 41, the stability of the mounting beam 4 can be further improved, and the mounting beam 4 can be prevented from bending under external impact.

[0037] Specifically, such as Figure 1 As shown, the protective component includes a baffle 400, which is L-shaped and is fixedly installed on the mounting beam 4 by fasteners. The baffle 400 can protect the upper part and the side of the bracket 100 at the same time. When the baffle 400 is worn, the baffle 400 can be quickly replaced by unscrewing the fasteners.

[0038] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
