Description

Technical Field

[0001] The invention relates to the technical field of mining machinery, and in particular to a mobile device for a drill box. Background Art

[0002] With the increase in infrastructure and underground engineering projects, anchor drilling rigs are increasingly used in the construction process. In related technologies, the movement of the drill box of the drilling rig on the feed cylinder is usually achieved by the following structure: a shaft is set on the peripheral wall of the cylinder, a copper sleeve is set on the shaft, a guide wheel is set outside the copper sleeve, and a chain is directly wound around the guide wheel, and the guide wheel is driven to rotate by the chain, thereby realizing the feeding movement of the drill box. In this structure, the copper sleeve and the mounting shaft are relatively stationary, while the guide wheel and the copper sleeve are relatively rotated.

[0003] However, due to the relative rotation between the guide wheel and the copper sleeve, sliding friction will be generated. At the same time, since the copper sleeve is made of a relatively soft material, this sliding friction will easily cause the copper sleeve to wear severely, thus shortening its service life. This not only increases the construction cost, but also the frequent replacement of the copper sleeve will affect the construction progress. Summary of the invention

DETAILED DESCRIPTION

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] The mobile device for a drill box according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0029] like Figures 1 to 5 As shown, the mobile device for a drill box according to an embodiment of the present invention includes a frame and a mobile component.

[0030] The frame includes a fixed frame 1, a movable frame 2 and a secondary oil cylinder 3. Optionally, the fixed frame 1 and the movable frame 2 are both composed of a bottom plate and a top plate and a support plate connecting the two. The support plate of the fixed frame 1 is a telescopic plate. The slidable design allows the position of the drill box 7 to be adjusted according to different construction requirements, which increases the applicability and flexibility of the device. The movable frame 2 moves between the bottom plate and the top plate of the fixed frame 1.

[0031] The extension and retraction direction of the secondary oil cylinder 3 is consistent with that of the fixed frame 1. The secondary oil cylinder 3 includes a cylinder rod 301, a primary cylinder barrel 302 and a secondary cylinder barrel 303. One end of the cylinder rod 301 is connected to the bottom plate of the fixed frame 1, and the other end of the cylinder rod 301 is slidably installed in the primary cylinder barrel 302. The two ends of the primary cylinder barrel 302 are respectively connected to the bottom plate and the top plate of the movable frame 2, that is, the cylinder rod 301 slides through the bottom plate of the movable frame 2 and is connected to the bottom plate of the fixed frame 1. The secondary cylinder barrel 303 is slidably installed on the primary cylinder barrel 302, and the length of the secondary cylinder barrel 303 is greater than half of the distance between the bottom plate and the top plate of the movable frame 2. The secondary cylinder barrel 303 moves between the bottom plate and the top plate of the movable frame 2.

[0032] For example, during the construction process, the top plate of the fixed frame 1 gradually extends to contact the rock wall, and then the cylinder rod 301 of the secondary oil cylinder 3 extends, so that the primary cylinder barrel 302 drives the movable frame 2 to move from the bottom plate of the fixed frame 1 to the top plate of the fixed frame 1, until the top plate of the movable frame 2 contacts the top plate of the fixed frame 1, and then the secondary cylinder barrel 303 of the secondary oil cylinder 3 moves from the bottom plate of the movable frame 2 to the top plate of the movable frame 2. Alternatively, the secondary cylinder barrel 303 moves first, and the primary cylinder barrel 302 moves later.

[0033] The moving assembly includes a fixed member 4, a transmission member 5 and two rotating members 6. The two rotating members 6 are respectively arranged at both ends of the secondary cylinder 303, and the transmission member 5 is rotatably arranged around the two rotating members 6. The transmission member 5 is connected to the support plate of the movable frame 2 through the fixed member 4. In addition, the drill box 7 is used to be installed on the transmission member 5, so that the transmission member 5 drives the drill box 7 to move.

[0034] Optionally, the transmission member 5 is a flexible transmission structure such as a chain or a belt, and the fixing member 4 is a fixing block, which is fixed to the movable frame 2 and the transmission member 5 by bolt connection. Preferably, when the transmission member 5 is a chain, when the secondary cylinder 303 moves from the bottom plate of the movable frame 2 to the bottom plate of the movable frame 2, under the positioning effect of the fixing member 4, the chain rotates simultaneously with the movement of the secondary cylinder 303.

[0035] like Figure 1 As shown, in the initial state, the drill box 7 is located at the bottom of the device. Figure 2 As shown, in the working state, the drill box 7 is moved to the top of the device through the extension and retraction of the fixing frame 1, the extension and retraction of the secondary oil cylinder 3 and the rotation of the chain.

[0036] It is understandable that in construction such as underground engineering, tunnel excavation or slope stabilization, the height of the borehole may vary from the ground to a higher rock surface. The drill box 7 can be moved from the bottom to the top, which can ensure that effective drilling operations can be carried out at different heights.

[0037] Optionally, the rotating member 6 includes a mounting shaft 601 and a positioning sleeve 602 and a roller bearing 603 mounted on the mounting shaft 601 . The roller bearing 603 is located on the side of the positioning sleeve 602 away from the secondary cylinder 303 . The roller bearing 603 is in contact with the positioning sleeve 602 , and the transmission member 5 surrounds the roller bearing 603 .

[0038] Therefore, the mobile device for the drill box of the embodiment of the present invention adopts cylindrical roller bearings 603 to replace the guide wheels in the related art, thereby replacing sliding friction with rolling friction, greatly reducing the friction coefficient, reducing energy consumption, and also reducing wear and tear, thereby extending the service life of the device.

[0039] In some embodiments, Figure 4and Figure 5 As shown, the rotating member 6 further includes a retaining ring 604 , which is connected to an end of the mounting shaft 601 away from the secondary cylinder 303 , and the roller bearing 603 is in contact with the retaining ring 604 .

[0040] It is understandable that the retaining ring 604 can prevent the roller bearing 603 from moving axially on the mounting shaft 601 due to vibration or axial force, thereby preventing the bearing from falling off or shifting. In addition, the retaining ring 604 and the positioning sleeve 602 together seal the roller bearing 603, prevent the lubricating oil from leaking, maintain the lubrication state inside the bearing, and also prevent external liquid from splashing onto the bearing.

[0041] Alternatively, if Figure 4 and Figure 5 As shown, the rotating member 6 further includes a screw 605, which passes through the retaining ring 604 and is connected to the end of the mounting shaft 601 away from the secondary cylinder 303. Specifically, the retaining ring 604 is provided with a through hole, and the end of the mounting shaft 601 is provided with an assembly hole. The screw 605 passes through the through hole of the retaining ring 604 and is installed in the assembly hole of the mounting shaft 601, thereby facilitating the disassembly and assembly of the retaining ring 604, and helping to simplify the installation and maintenance process of the roller bearing 603.

[0042] Furthermore, there are multiple screws 605, and the multiple screws 605 are distributed at intervals around the central axis of the installation shaft 601. The uniform distribution of the multiple screws 605 helps to disperse the pressure and improve the durability of the structure.

[0043] In some embodiments, Figure 4 and Figure 5 As shown, the outer edge of the positioning sleeve 602 has a chamfer, and the chamfer of the positioning sleeve 602 is located at one end of the positioning sleeve 602 close to the secondary cylinder 303. In addition, the outer edge of the retaining ring 604 also has a chamfer, and the chamfer of the retaining ring 604 is located at one end of the retaining ring 604 away from the secondary cylinder 303.

[0044] It can be understood that the retaining ring 604 and the positioning sleeve 602 are used to prevent the surrounding liquid with a certain viscosity and easy to crystallize from splashing onto the roller bearing 603, so that the liquid flows naturally along the guide angle under gravity, avoiding the roller bearing 603 from getting stuck, and improving the safety and stability of the device operation.

[0045] Optionally, the guide angle of the positioning sleeve 602 and the guide angle of the retaining ring 604 are greater than or equal to 30° and less than or equal to 60°, so as to avoid the problem of inconvenience of liquid flow due to too small an angle and stress concentration caused by too large an angle.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the connection between the fixing member 4 and the movable frame 2 is located in the middle of the movable frame 2 .

[0047] It is understandable that setting the connection position between the fixing member 4 and the movable frame 2 in the middle of the movable frame 2 helps to evenly distribute the force and reduce the structural deformation caused by the eccentric load, thereby improving the stability and service life of the entire mobile device. More importantly, after calculation, it can meet the needs of the drill box 7 to slide from the bottom end of the movable frame 2 to the top end, effectively utilizing the overall length of the movable frame 2.

[0048] And, if Figure 3 As shown, there are two moving assemblies, which are arranged on two sides of the secondary cylinder 303 opposite to each other.

[0049] It is understandable that two moving components are symmetrically arranged on both sides of the secondary cylinder 303. Such a design can ensure the balance of the drill box 7 during movement and reduce the shaking and noise caused by unbalanced weight.

[0050] Therefore, the optimization of the position of the fixing member 4 and the symmetrical arrangement of the moving components enhance the mechanical strength and durability of the entire device and adapt to the complex and changeable construction environment.
