Description

Technical Field

[0001] This application relates to the field of tunnel excavation and support technology, and in particular to a rock bolt drilling rig with support function. Background Technology

[0002] Anchor bolt drilling rigs are commonly used machines in tunnel excavation. They primarily improve tunnel stability and prevent collapse during construction by driving anchor bolts into the tunnel. However, when anchor bolts are inserted, they compress the surrounding soil, potentially threatening the lives of construction workers should a tunnel collapse occur. Therefore, support components can be installed on the anchor bolt drilling rig to protect the tunnel.

[0003] Currently, the support components on bolt drilling rigs mainly consist of a support net and a top brace. The support net acts on the tunnel wall, while the top brace acts on the tunnel roof. In existing technology, to improve support effectiveness, the support net is relatively large and cannot be automatically folded. Manual folding would make operation more cumbersome, and if left folded, the bolt drilling rig might obstruct surrounding vehicles when traveling on public roads. Furthermore, the support arm on bolt drilling rigs is mostly directly connected to the rig body; if the tunnel is high, the support arm may not be able to reach the tunnel roof. Utility Model Content

[0004] One objective of this application is to provide a bolt drilling rig with support function that can solve at least one of the defects in the above-mentioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a rock bolt drilling rig with support function, comprising a vehicle body and a support assembly, wherein a support arm is rotatably mounted on the vehicle body, and a connector is provided at the end of the support arm; the support assembly includes a main support net and two secondary support nets, wherein an installation head is provided on the main support net for installation in conjunction with the connector, and the two secondary support nets are respectively hinged to both sides of the main support net; an adjustment mechanism for adjusting the rotation angle of the secondary support nets is provided between the main support net and the secondary support nets.

[0006] With the above settings, when the rock bolt drilling rig is moving, the auxiliary support nets on both sides can be folded onto the main support net through the adjustment mechanism, further reducing the overall size of the support assembly and preventing the support assembly from affecting other vehicles when it is deployed. When the rock bolt drilling rig reaches the designated support location, the auxiliary support nets on both sides can be deployed through the adjustment mechanism, and then the support arm can be used to make the support assembly fit against the roadway wall, thereby improving the support effect of the support assembly.

[0007] Preferably, the adjusting mechanism includes a first adjusting member, a second adjusting member, and a connecting rod. A mounting base is provided on the main support mesh. The first adjusting member and the second adjusting member are respectively hinged to the mounting base and the secondary support mesh. The other ends of the first adjusting member and the second adjusting member are hinged to the connecting rod, and there is a height difference between them. This configuration allows the secondary support mesh to rotate around the main support mesh via the first and second adjusting members.

[0008] Preferably, both the first and second adjusting members are arc-shaped, and the rotation angle of the secondary support net is 0° to 180°. A drive assembly is installed on the mounting base, which is used to drive the first and second adjusting members to rotate. With this configuration, the operator can control the first and second adjusting members to drive the secondary support net to rotate via the drive assembly. When the angle between the secondary support net and the main support net is 0°, the support assembly is in a folded state, which is suitable for the movement of the anchor drilling rig. When the angle between the secondary support net and the main support net is 180°, the support assembly is in an unfolded state, which is suitable for the operation of the anchor drilling rig.

[0009] Preferably, the drive assembly includes a telescopic cylinder, the mounting base portion protrudes outward to form a protrusion, one end of the telescopic cylinder is hinged to the connecting rod, and the other end is hinged to the protrusion. With this configuration, the secondary support net can be rotated by the telescopic cylinder. When the telescopic cylinder is in the extended state, it generates a thrust on the connecting rod, thereby causing the secondary support net to move around the movement trajectories of the first and second adjusting members.

[0010] Preferably, the system also includes a support arm, with a connecting seat fixedly mounted on the vehicle body. The support arm is rotatably mounted on the connecting seat, and the support arm is rotatably mounted on the support arm. This configuration allows for more comprehensive support of the roadway by using the support arm and the support arm to support the sides and top of the roadway respectively. The angle between the support arm and the support arm can be adjusted according to actual needs.

[0011] Preferably, a heightening pad is installed between the support arm and the connecting seat. The heightening pad has a first connecting part and a second connecting part. The first connecting part is rotatably connected to the support arm, and the second connecting part is fixedly connected to the connecting seat. This configuration allows the installation height of the support arm to be increased using the heightening pad, enabling the support arm and the support arm to adapt to the height of the roadway.

[0012] Preferably, a first hydraulic cylinder for adjusting the angle of the support arm is provided between the support arm and the raising pad, and a second hydraulic cylinder for adjusting the angle of the support arm is provided between the support arm and the guard arm. With this configuration, when the support point position in the roadway changes, the pitch angle of the support arm and the guard arm can be adjusted using the first and second hydraulic cylinders.

[0013] Preferably, both the support arm and the protective arm are telescopic, and both are equipped with locking components for controlling their telescopic length. This configuration allows the locking components to be opened as needed, the support arm and protective arm to be adjusted to a suitable length, and then the length of the support arm and protective arm to be locked using the locking components, ensuring that the support arm and protective arm fit snugly against the point to be supported.

[0014] Preferably, a connecting plate is hinged to the top of the support arm, and a support rod and a top support are installed on the connecting plate. The top support is T-shaped, and its upper surface is curved. This configuration allows the top of the tunnel to be supported by the top support and the support rod, and the curvature of the upper surface of the top support can better adapt to the arched tunnel.

[0015] Preferably, there are two support rods, each installed at one end of the connecting plate. Each support rod includes a fixed section and a rotating section. The fixed section is hinged to the connecting plate, and the rotating section is rotatably installed at the end of the fixed section. This arrangement allows the left and right-side support rods to cooperate in supporting the top of the roadway. When the angle between the rotating section and the fixed section is 90°, the support effect of the support rods can be further improved.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] The main support net has secondary support nets hinged to both sides. The folding and unfolding of these secondary support nets is controlled by an adjustment mechanism. When folded, the overall size of the support assembly is further reduced, preventing it from affecting other vehicles when unfolded. When unfolded, the support arms allow the support assembly to fit snugly against the tunnel wall, improving its support effectiveness. Furthermore, the adjustment mechanism can be controlled by a drive assembly to rotate the secondary support nets, further enhancing their ease of rotation.

[0018] A heightening pad is installed between the mounting base and the support arm to increase the installation height of the support arm, further increasing the maximum length of the support arm and the support arm, enabling the bolt drilling rig to support higher roadways. This invention can adapt to more working scenarios and has advantages such as good support effect and high flexibility. Attached Figure Description

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] One aspect of this application provides an anchor drilling rig with support function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one preferred embodiment includes a vehicle body 1 and a support assembly 2. A support arm 100 is rotatably mounted on the vehicle body 1. The end of the support arm 100 is provided with a connector 101 for mounting the support assembly 2. The support location of the support assembly 2 can be changed by adjusting the angle of the support arm 100. The support assembly 2 includes a main support net 21 and two secondary support nets 22. The main support net 21 is provided with mounting heads 200 for mounting with the connector 101. The two secondary support nets 22 are respectively hinged to both sides of the main support net 21, allowing the support assembly 2 to be unfolded / folded. Furthermore, to improve the unfolding / folding speed of the support assembly 2, an adjustment mechanism 3 for adjusting the rotation angle of the secondary support nets 22 is provided between the main support net 21 and the secondary support nets 22.

[0031] Understandably, when the bolt drilling rig is moving, the secondary support nets 22 on both sides can be folded onto the main support net 21 through the adjustment mechanism 3, thereby reducing the overall size of the support assembly 2 and preventing the support assembly 2 from affecting the passage of itself or other vehicles around it when it is unfolded. When the bolt drilling rig reaches the designated support location, the secondary support nets 22 on both sides can be unfolded through the adjustment mechanism to increase the overall support area, and then the support arm 100 can be used to make the support assembly 2 fit against the roadway wall, thereby providing more stable support for the roadway wall.

[0032] Specifically, such as Figure 2 and Figure 3As shown, the adjustment mechanism 3 includes a first adjusting member 31, a second adjusting member 32, and a connecting rod 33. A mounting base 300 is provided on the main support net 21. One end of the first adjusting member 31 is hinged to the mounting base 300, and the other end is hinged to the connecting rod 33. One end of the second adjusting member 32 is hinged to the secondary support net 22, and the other end is hinged to the connecting rod 33. By controlling the rotation of the first adjusting member 31 and the second adjusting member 32, the secondary support net 22 can rotate around the main support net 21.

[0033] It should be noted that there should be a certain height difference between the first adjusting member 31 and the second adjusting member 32 to avoid the first adjusting member 31 and the second adjusting member 32 scraping each other when the secondary support net 22 rotates.

[0034] Furthermore, both the first adjusting member 31 and the second adjusting member 32 are arc-shaped. When the support assembly 2 is in the folded state, the inner arcs of the first adjusting member 31 and the second adjusting member 32 are in relative positions. The rotation angle of the secondary support net 22 is 0°~180°. When the angle between the secondary support net 22 and the main support net 21 is 0°, the support assembly 2 is in the folded state, which is suitable for the movement of the anchor drilling rig. When the angle between the secondary support net 22 and the main support net 21 is 180°, the support assembly 2 is in the unfolded state, which is suitable for the operation of the anchor drilling rig.

[0035] It should be understood that the anchor bolt drilling rig needs to change positions multiple times for support during operation. Due to the limited space in the tunnel, in order to allow the anchor bolt drilling rig to quickly pass through narrow sections, the secondary support net 22 is usually folded onto the main support net 21 before the rig is moved. However, controlling the rotation of the secondary support net 22 by manually folding it is not only time-consuming but also increases the workload of the construction personnel.

[0036] To address the aforementioned issues, in some embodiments of this application, a drive assembly is installed on the mounting base 300. The drive assembly can actively drive the first adjusting member 31 and the second adjusting member 32 to rotate, thereby enabling remote control of the rotation of the secondary support net 22.

[0037] Specifically, such as Figure 2 and Figure 4As shown, the drive assembly includes a telescopic cylinder 400. A portion of the mounting base 300 protrudes outwards to form a protrusion 301. One end of the telescopic cylinder 400 is hinged to a connecting rod 33, and the other end is hinged to the protrusion 301. The extension / retraction of the telescopic cylinder 400 controls the rotation direction and angle of the sub-support net 22. By controlling the extension and retraction of the telescopic cylinder 400, the operator can move the sub-support net 22 around the movement trajectory of the first adjusting member 31 and the second adjusting member 32. When the telescopic cylinder 400 extends outwards, it generates a thrust on the connecting rod 33, causing the sub-support net 22 to rotate in a foldable direction. When the telescopic cylinder 400 retracts inwards, it generates a pull on the connecting rod 33, causing the sub-support net 22 to rotate in an unfoldable direction.

[0038] In one embodiment of this application, such as Figure 5 As shown, the anchor bolt drilling rig also includes a support arm 500. A connecting seat 4 is fixedly installed on the vehicle body 1. The support arm 500 is rotatably mounted on the connecting seat 4, and the support arm 100 is rotatably mounted on the support arm 500. The support arm 500 and the support arm 100 respectively support the sides and top of the roadway, thereby providing more comprehensive support for the roadway. The angle between the support arm 500 and the support arm 100 can be adjusted according to actual needs.

[0039] Furthermore, such as Figure 5 As shown, a heightening pad 5 is installed between the support arm 500 and the connecting seat 4. The heightening pad 5 is provided with a first connecting part 51 and a second connecting part 52. The first connecting part 51 is rotatably connected to the support arm 500, and the second connecting part 52 is fixedly connected to the connecting seat 4. The installation height of the support arm 500 can be increased by the heightening pad 5, thereby adjusting the support arm 500 and the support arm 100 to adapt to the roadway height.

[0040] Understandably, when the height of the roadway is reduced, the operator can also remove the riser pad 5 to lower the support height of the support arm 500 and the support arm 100. After the riser pad 5 is removed, the support arm 500 can be directly rotatably connected to the connecting seat 4 through the second connecting part 52.

[0041] In this embodiment, a first hydraulic cylinder 600 for adjusting the angle of the support arm 500 is provided between the support arm 500 and the raising pad 5, and a second hydraulic cylinder 601 for adjusting the angle of the support arm 100 is provided between the support arm 500 and the support arm 500. When the support point of the roadway changes, the pitch angle of the support arm 500 and the support arm 100 can be adjusted by the first hydraulic cylinder 600 and the second hydraulic cylinder 601 respectively, further improving the flexibility of the bolt drill rig support.

[0042] Furthermore, both the support arm 500 and the support arm 100 have telescopic functions, and both are equipped with locking components to control their telescopic length. When the length of the support arm 500 or the support arm 100 is not suitable, the locking components can be opened, and the support arm 500 and the support arm 100 can be adjusted to a suitable length. Then, the length of the support arm 500 and the support arm 100 can be locked using the locking components, ensuring that the support arm 500 and the support arm 100 are in close contact with the point to be supported. This further enhances the support function of the anchor bolt drilling rig, enabling it to be used in more complex environments.

[0043] In this embodiment, as Figure 5 and Figure 6 As shown, a connecting plate 6 is hinged to the top of the support arm 500. A support rod 7 and a top support 700 are mounted on the connecting plate 6, with the top support 700 being T-shaped. During support operations, the support arm 500 is raised, and the support rod 7 and the top support 700 are brought into contact with the top of the tunnel, thereby providing support for the tunnel's top. Furthermore, since the top of some tunnels is arched, the upper surface of the top support 700 can be made curved to better adapt to the arched tunnel.

[0044] Specifically, such as Figure 5 As shown, there are two support rods 7, which are respectively installed at both ends of the connecting plate 6 to ensure that the two support rods 7 can form the maximum support area. Each support rod 7 includes a fixed section 71 and a rotating section 72. The fixed section 71 is hinged to the connecting plate 6, and the rotating section 72 is rotatably installed at the end of the fixed section 71. During support, the rotating section 72 can be rotated. When the angle between the rotating section 72 and the fixed section 71 is 90°, the support effect of the support rod 7 can be further improved.

[0045] 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.
