DETAILED DESCRIPTION
[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0033] The existing tunnel rock drilling, especially the drilling of holes with a depth of about six meters, can be performed by manual rod connection, automatic rod connection and single long drill rod 31.
[0034] The manual rod connection has the disadvantages of low construction efficiency and increased labor cost due to the need for manual intervention.
[0035] Although the automatic rod connecting solves most of the disadvantages of the manual rod connecting, the automatic rod connecting has a higher cost than the common rock drill vehicle due to the relatively complex technology and the technology integration, and the time loss caused by the rod changing is inevitable. More importantly, the rock drilling hole with a depth of about six meters is indeed a waste of the rock drill vehicle with the automatic rod connecting, and the real performance of the rock drill vehicle cannot be fully utilized.
[0036] For the rock drill vehicle with the single long drill rod 31, although the whole vehicle has a low cost, the long drill rod 31 is difficult to choose due to the many adverse factors caused by the rod swinging during the fast rotation of the rock drill.
[0037] Therefore, in order to solve the defect of the single long drill rod 31 swinging, the automatic auxiliary drill rod supporting device 10 is added to the rock drill advancing beam 20, so that the single long drill rod 31 can be stable like Mount Tai during the easy rod swinging stage. Thus, the single long drill rod rock drill vehicle can reduce the whole vehicle procurement cost, stabilize the construction, and improve the construction efficiency.
[0038] The embodiments of the present application will be described below in combination with Figures 1 to 10 The embodiments of the present application will be described below in combination with
[0039] According to the embodiments of the present application, in a first aspect, an auxiliary drill rod supporting device 10 is provided for a drilling equipment 100, which comprises an assembly base 11, an arm swinging assembly 12, and a drill rod supporting assembly 13. The assembly base 11 is suitable for being connected with the advancing beam 20 of the drilling equipment 100. The arm swinging assembly 12 is rotationally connected with the assembly base 11. The drill rod supporting assembly 13 is connected with the arm swinging assembly 12 and is suitable for swinging with the arm swinging assembly 12 relative to the assembly base 11. The drill rod supporting assembly 13 comprises a fixed jaw block 131 and a movable jaw block 132. The fixed jaw block 131 is fixedly connected with the arm swinging assembly 12. The movable jaw block 132 is rotationally connected with the fixed jaw block 131 through a rotating shaft 133. When the movable jaw block 132 is closed with the fixed jaw block 131, a supporting channel 134 for supporting the drill rod 31 of the drilling equipment 100 is formed between the movable jaw block 132 and the fixed jaw block 131. The extension direction of the supporting channel 134 is the same as the axial direction of the rotating shaft 133.
[0040] The auxiliary drill rod supporting device 10 provided by the embodiment of the utility model, when the fixed jaw block 131 and the movable jaw block 132 in the drill rod supporting assembly 13 are closed, a supporting channel 134 is formed between the two, the drill rod 31 passes through the supporting channel 134, and a gap is left between the drill rod 31 and the supporting channel 134 instead of the drill rod being clamped, which allows the drill rod 31 to rotate in the supporting channel, meanwhile, the fixed jaw block 131 and the movable jaw block 132 in the drill rod supporting assembly 13 can stably support the drill rod 31, so that the drill rod 31 is effectively supported and stabilized during rotation, the phenomenon of the drill rod being thrown due to the length of the drill rod is greatly reduced, the straightness of the drill rod 31 during drilling is ensured, and therefore the quality of the formed hole is improved. In addition, the utility model can prevent the drill rod from deviating or vibrating during rotation, effectively reduces the eccentric and staggered stress of the connecting sleeve and the drill rod tail end caused by the drill rod being thrown, avoids early wear and tear, prevents the drill rod from being deformed or broken, prolongs the service life of the drill rod 31 and related components, reduces the frequency of replacement due to wear and tear and damage, and reduces the material cost.
[0041] Specifically, the auxiliary drill rod supporting device 10 is fixed to the advancing beam 20 of the drilling equipment 100 as a whole through the assembly base 11. The swing arm assembly 12 can drive the drill rod supporting assembly 13 to swing so as to be close to the drill rod 31 when the drill rod 31 needs to be supported or to be away from the drill rod 31 when the drill rod 31 needs to be released. The drill rod supporting assembly 13 is used for supporting or releasing the drill rod 31.
[0042] When the rock drill device 30 starts to work, the movable jaw block 132 rotates away from the fixed jaw block 131, the two are opened, and the drill rod 31 is released. Then, the swing arm assembly 12 drives the drill rod supporting assembly 13 to swing, so that the movable jaw block 132 is away from the fixed jaw block 131 and the drill rod 31, and therefore the advancing of the drill rod 31 can be carried out. Subsequently, the rock drill device 30 continues to advance forward to complete a drilling.
[0043] Before the second drilling, the swing arm assembly 12 drives the drill rod supporting assembly 13 to swing, so that the movable jaw block 132 is close to the fixed jaw block 131 and the drill rod 31, and the movable jaw block 132 rotates close to the fixed jaw block 131, the two are closed, and the drill rod 31 is supported, that is, the reset of the auxiliary drill rod supporting device before the second drilling is completed. After this reciprocating completion, subsequent drilling is completed.
[0044] In some embodiments, the swing arm assembly 12 comprises a swing arm 121 and a swing arm driving member, one end of the swing arm 121 is rotationally connected with the assembly base 11, and the other end of the swing arm 121 is connected with the driving end of the swing arm driving member, and the swing arm driving member is suitable for driving the swing arm 121 to swing relative to the assembly base 11.
[0045] Specifically, the rotational connection between the swing arm 121 and the assembly base 11 allows the swing arm 121 to swing freely within a certain range, which enables the entire device to adjust the working posture flexibly according to actual needs, adapt to different working environments and task requirements. For example, when the auxiliary drill supporting device 10 provided in the embodiment is assembled to the push beam 20 of the drilling equipment 100, the swing driving member drives the swing arm assembly 12 to approach the drill rod 31, so that the drill supporting assembly 13 supports the drill rod 31, thereby achieving the effect of auxiliary drill supporting. Alternatively, the drill supporting assembly 13 releases the drill rod 31, at which time the swing arm driving member drives the swing arm 121 to move away from the drill rod 31, thereby avoiding hindering the advancement or retraction of the drill rod 31.
[0046] In some embodiments, the swing arm driving member includes a swing arm driving cylinder 122, one end of the swing arm driving cylinder 122 is rotationally connected with the assembly base 11, and the other end of the swing arm driving cylinder 122 is rotationally connected with the other end of the swing arm 121; the fixed jaw block 131 is fixedly connected with the swing arm 121.
[0047] Since both ends of the swing arm driving cylinder 122 are rotationally connected, the swing arm 121 can swing freely within a larger range, thereby meeting the requirement of large-angle swinging of the swing arm 121.
[0048] As a direct driving component, the swing arm driving cylinder 122 can realize accurate control of the angle and position of the swing arm 121, ensuring that each action can achieve the expected effect, thereby improving the high-precision auxiliary effect on the drill rod 31.
[0049] By using the swing arm driving cylinder 122 instead of traditional gears or other complex transmission mechanisms, not only the number of parts is reduced, the manufacturing cost is lowered, but also the maintenance is more convenient. At the same time, the swing arm driving cylinder 122 can complete the same function in a smaller space, thereby saving installation space, and is particularly suitable for compact equipment. In addition, the swing arm driving cylinder 122 can quickly respond to control signals, realize rapid start and stop, and is conducive to improving construction efficiency.
[0050] Specifically, the swing arm driving cylinder 122 can be an oil cylinder, an air cylinder or an electric cylinder.
[0051] In some embodiments, the swing arm 121 includes a swing arm base 1211 and a swing arm body 1212, the swing arm base 1211 is rotationally connected with the assembly base 11, one end of the swing arm body 1212 is fixedly connected with the swing arm base 1211, and the other end of the swing arm body 1212 is rotationally connected with the other end of the swing arm driving cylinder 122.
[0052] The swing arm 121 is divided into a swing arm base 1211 and a swing arm body 1212, and higher flexibility and stronger adaptability are achieved through a reasonable connection mode, which also facilitates production and maintenance. The swing arm body 1212 is directly driven by the swing arm driving cylinder 122, reducing intermediate transmission links and thus improving the response speed and dynamic performance of the system.
[0053] In addition, the swing arm driving cylinder 122 directly acts on the end of the swing arm body 1212, optimizing the force transmission path, reducing energy loss, and improving work efficiency.
[0054] In some embodiments, the rod supporting assembly 13 further comprises a rod supporting driving cylinder 135, one end of which is rotationally connected with the swing arm assembly 12, and the other end of which is rotationally connected with the movable clamp block 132.
[0055] The rotational connection between the rod supporting driving cylinder 135, the swing arm assembly 12 and the movable clamp block 132 provides an additional degree of freedom for the rod supporting assembly 13, enabling it to more flexibly adapt to different working postures and position requirements. The rod supporting driving cylinder 135 can drive the movable clamp block 132 to rotate about the rotation shaft 133, so as to drive the movable clamp block 132 to approach the fixed clamp block 131 until the movable clamp block 132 and the fixed clamp block 131 are clamped and closed, forming a supporting channel 134 and achieving effective support of the drill rod 31; or drive the movable clamp block 132 to move away from the fixed clamp block 131 so that the movable clamp block 132 and the fixed clamp block 131 are opened, achieving release of the drill rod 31.
[0056] By applying force to the movable clamp block 132 through the rod supporting driving cylinder 135, precise control of the rod supporting action can be achieved, ensuring that each operation can achieve the expected effect and facilitating high-precision positioning to smoothly support the drill rod 31.
[0057] Compared with other complex transmission mechanisms, the use of the rod supporting driving cylinder 135 simplifies the mechanical structure, reduces manufacturing costs, and is also conducive to later maintenance. At the same time, the rod supporting driving cylinder 135 can directly respond to control signals, quickly start and stop, improve the response speed and dynamic performance of the system, and thus improve the overall construction efficiency.
[0058] In some embodiments, two swing arms 121 are arranged side by side, and two movable clamp blocks 132 and two fixed clamp blocks 131 are arranged, the two movable clamp blocks 132 are arranged between the two swing arms 121, and the supporting surfaces of the movable clamp blocks 132 and the supporting surfaces of the fixed clamp blocks 131 do not overlap in the length extension direction of the supporting channel 134.
[0059] By arranging two swing arms 121, two movable jaw blocks 132 and two fixed jaw blocks 131 side by side, the supporting surfaces of the movable jaw blocks 132 and the fixed jaw blocks 131 do not overlap along the length direction of the supporting channel 134, which can increase the contact area with the drill rod 31 in the length direction of the drill rod 31, and ensure that the drill rod 31 is stably supported.
[0060] In addition, the jaw block assembly is arranged between the two swing arms 121, which makes full use of the limited space and makes the entire device structure more compact.
[0061] In some embodiments, the fixed jaw block 131 and the swing arm body 1212 are integrally formed.
[0062] By integrally forming the fixed jaw block 131 and the swing arm body 1212, the connection point between the two is eliminated, thereby significantly enhancing the rigidity and strength of the overall structure, thereby improving the supporting effect on the drill rod 31 and effectively avoiding many adverse effects caused by rod whipping during the rock drilling process of a single long drill rod 31.
[0063] Compared with the traditional split design, integrally forming can reduce the number of parts and assembly processes, reduce manufacturing complexity and cost, and also help improve production efficiency.
[0064] Since there are no additional connecting components, the integrally formed design reduces potential failure points and reduces the need and cost of routine maintenance.
[0065] In some embodiments, at least one shock absorber 14 is further included, and the shock absorber 14 is connected with the swing arm assembly 12.
[0066] By arranging the shock absorber 14, the impact or motion-induced vibration generated during the drilling process of the drill rod 31 can be effectively absorbed and attenuated, preventing the vibration from being transmitted to the swing arm assembly 12 and other connected components, thereby improving the stability and reliability of the entire system, improving the effect of assisting the drill rod 31, and avoiding rod whipping.
[0067] At the same time, by arranging the shock absorber 14, the impact force borne by the swing arm driving cylinder 122, the drill rod supporting driving cylinder 135 and other key components can also be reduced, prolonging their service life and reducing the failure rate.
[0068] In addition, arranging the shock absorber 14 can also reduce the noise caused by vibration and reduce the construction noise of the drilling equipment 100 during operation.
[0069] In some embodiments, two components are connected by a rotating shaft, and a spacer sleeve 15 is arranged on the rotating shaft to limit the rotating component.
[0070] According to the embodiments of the utility model, the second aspect further provides a drilling equipment 100, including the propulsion beam 20, and be located in the propulsion beam 20's rock drill device 30, the drill holder 40, the propulsion drive device 50, the top frame device 60 and the auxiliary drill holder device 10 in the above embodiment. Rock drill device 30 includes drill rod 31, propulsion drive device 50 is suitable for propelling rock drill device 30 and the drill holder 40 along the reciprocating linear motion of propulsion beam 20, drill rod 31 passes through the drill hole of drill holder 40 and the center hole of top frame device 60 in turn, auxiliary drill holder device 10 is connected with propulsion beam 20 and is located between rock drill device 30 and top frame device 60.
[0071] Specifically, the propulsion beam 20 serves as a support structure of the entire equipment, and is used for mounting and fixing other components.
[0072] The rock drill device 30 includes the drill rod 31, which is responsible for the actual drilling operation. The rock drill device 30 is installed on the propulsion beam 20 and realizes the reciprocating linear motion along the propulsion beam 20 under the driving of the propulsion drive device 50.
[0073] The drill holder 40 is provided with a drill hole, and the drill rod 31 passes through the drill hole to reduce the rod whipping of the drill rod 31 during the construction process.
[0074] The propulsion drive device 50 can drive the rock drill device 30, the cable drum device 80 and the drill holder 40 to perform the reciprocating linear motion along the propulsion beam 20, and provide the thrust and tension required for drilling.
[0075] The top frame device 60 is provided with a center hole, and the drill rod 31 also passes through the hole to play a supporting and guiding role and ensure the stability of the drill rod 31 during the drilling process. When the auxiliary drill holder device 10 supports the drill rod 31, the drill rod 31 also passes through the supporting channel 134, so that the auxiliary drill holder device 10 can effectively support the drill rod 31 and also guide the drill rod 31 through the supporting channel 134.
[0076] During the single long drill rod 31 rock drilling starting process, although the drill holder 40 is arranged in the middle of the propulsion beam 20, the drill rod 31 is deformed and bent due to the thrust of the rock drilling propulsion drive device 50 in the initial stage of drilling, and the drill rod 31 between the drill holder 40 and the top frame device 60 appears rod whipping under high-speed rotation due to the eccentricity caused by deformation and bending under the high-speed rotation of the rock drill, which is easy to cause the early damage of each component during rock drilling.
[0077] The drilling equipment 100 provided by the embodiment sets the auxiliary drill supporting device 10 on the advancing beam 20 and between the rock drill device 30 and the top frame device 60. The auxiliary drill supporting device 10 is set so that the drill rod 31 is effectively supported and stabilized during rotation, greatly reduces the rod whipping phenomenon caused by the length of the rod, ensures the straightness of the drill rod 31 during drilling, and thus improves the quality of the hole. In addition, the supporting channel 134 formed by the fixed jaw block 131 and the movable jaw block 132 in the drill supporting assembly 13 can stably support the drill rod 31, prevent it from deviating or vibrating during rotation, effectively reduce the eccentric and staggered stress of the connecting sleeve and the drill tail end caused by rod whipping, avoid early wear and tear, prevent the drill rod from deforming or breaking, prolong the service life of the drill rod 31 and related components, reduce the frequency of replacement due to wear and tear, and reduce material costs.
[0078] Because the drilling equipment 100 includes the auxiliary drill supporting device 10, it has all the beneficial effects of the auxiliary drill supporting device 10, and the remaining technical effects will not be repeated here.
[0079] In some embodiments, a position sensor 70 is further included, which is arranged on the assembly base 11 of the auxiliary drill supporting device 10 or the advancing beam 20, and is in communication connection with the controller. The position sensor 70 is used to send a position signal to the controller after being triggered, and the controller is adapted to control the auxiliary drill supporting device 10 to switch between the drill supporting working position and the avoiding working position according to the position signal.
[0080] Through the cooperative work of the position sensor 70 and the controller, the system can realize automatic operation, reduce manual intervention, improve work efficiency, and reduce operation difficulty.
[0081] In some embodiments, the swing arm driving cylinder 122 is connected with a first valve block pressure sensor, and the drill supporting driving cylinder 135 is connected with a second valve block pressure sensor. The first valve block pressure sensor and the second valve block pressure sensor are respectively in communication connection with the controller.
[0082] In this way, the controller can realize automatic control of the auxiliary drill supporting device 10 and realize quick switching of the auxiliary drill supporting device 10 between the drill supporting working position and the avoiding working position in combination with the signal acquisition and feedback of the position sensor, the first valve block pressure sensor and the second valve block pressure sensor.
[0083] The drilling equipment 100 provided by the embodiment adds an auxiliary drill rod supporting device 10 to the drill rod 31 in the most serious construction phase of the swing rod, automatically controls the opening and closing of the drill rod supporting assembly 13 and the back and forth reset function of the swing arm assembly 12 of the auxiliary drill rod supporting device 10 through the position sensor 70 and the controller, thereby providing reliable guarantee for the long drill rod 31 construction. The drilling equipment 100 provided by the embodiment not only reduces the consumption of vulnerable parts caused by the swing rod, but also does not affect the original construction scene. The actual construction saves the cost and improves the construction efficiency compared with the rock drilling by the joint rod mode.
[0084] Specifically, in the embodiment, the position sensor 70 adopts a proximity switch. The proximity switch is installed on the advancing beam 20 through a mounting bracket. The supporting plate of the drill rod supporting device 40 is driven by the advancing drive device 50 to advance along the advancing beam 20 together with the drill rod 31. In this process, the supporting plate of the drill rod supporting device 40 will touch the proximity switch, thereby triggering the proximity switch sensor, sending a signal to the controller, and controlling the action of the auxiliary drill rod supporting device 10 through the controller receiving and processing the signal.
[0085] In some embodiments, the back and forth swing and the folding and unfolding of the drill rod supporting assembly 13 of the auxiliary drill rod supporting device 10 are realized by controlling the extension and retraction of the swing arm drive cylinder 122 and the drill rod drive cylinder 135 of the auxiliary drill rod supporting device 10 through the signal transmission and program logic between the controller, the hydraulic valve block pressure signal and the proximity switch.
[0086] The system defines the position where the swing arm assembly 12 of the auxiliary drill rod supporting device 10 swings close to the drill rod 31 to the position where the drill rod supporting assembly 13 is folded as the initial point set by the program. When the rock drilling machine device 30 starts to work, the supporting plate of the drill rod supporting device 40 touches the proximity switch, the proximity switch monitors the signal and transmits the signal to the controller, and the controller processes the signal to give an instruction to the drill rod drive cylinder 135. The drill rod drive cylinder 135 drives the movable jaw block 132 to rotate around the rotating shaft 133, the movable jaw block 132 moves away from the fixed jaw block 131, and the drill rod 31 is loosened.
