Description

Technical Field

[0001] This invention relates to the field of anchor cable technology, and in particular to an anchor cable construction device and its construction method. Background Technology

[0002] With the increasing number of urgent, difficult, and dangerous tunnel projects in my country, traditional anchoring methods are no longer sufficient to meet the requirements of surrounding rock support. Therefore, active support methods using anchor cables to reinforce structures are becoming more widely used. Currently, anchor cable support is mainly applied in fields such as foundation pits, bridges, coal mines, and slopes. The structure of an anchor cable includes an anchored section and a free section. After drilling a hole in the rock stratum, the anchored section of the anchor cable is anchored into the borehole, while the free section is exposed outside the rock stratum. Prestress is provided by tensioning the free section of the anchor cable to achieve the anchoring effect.

[0003] There are two main types of existing anchor cable construction methods: single anchor cable construction and bundled anchor cable construction. Single anchor cable construction is suitable for coal mine and tunnel support, while bundled anchor cable construction is suitable for slope, foundation pit, and tunnel (bundled anchor cables are used when the required anchoring force is large) support.

[0004] In the field of coal mine and tunnel support, the anchor cable construction process includes: drilling, hole cleaning, anchor cable installation, installation of bearing plates / anchors, and tensioning. The anchor cable installation process includes the delivery of anchoring agent, the delivery of anchor cables, and the mixing of anchor cables. Due to the small cross-sectional area and shallow depth of coal mines, only the anchor cable delivery process within the anchor cable installation can be automated; the remaining processes are performed manually. However, the cross-sectional area of ​​tunnels is much larger than that of coal mines, requiring manual high-altitude work using suspended platforms for anchor cable installation. Manual labor presents significant safety hazards, high labor intensity, and low efficiency.

[0005] Therefore, the development of automated and mechanized construction devices for single anchor cables in coal mine and tunnel support is urgently needed. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an anchor cable construction device for the fields of coal mine and tunnel support, which can realize the automation and mechanization of the anchor cable installation process of a single anchor cable. It solves the technical problems of the prior art, which involves large safety hazards, high labor intensity and low work efficiency when anchor cable construction is carried out manually.

[0016] Optionally, the anchor cable pushing assembly further includes: a first rotary driver and a second rotary driver, wherein the first clamping member and the second clamping member are respectively a first roller and a second roller, and the output ends of the first rotary driver and the second rotary driver are respectively fixedly connected to the first roller and the second roller; the first rotary driver is used to drive the first roller to rotate, and the second rotary driver is used to drive the second roller to rotate, so that the first roller and the second roller rotate in opposite directions and drive the anchor cable clamped by them to be conveyed upward; a spacing adjustment member, the spacing adjustment member being connected to the first rotary driver and / or the second rotary driver, and used to drive the first rotary driver and / or the second rotary driver to move laterally to adjust the lateral spacing between them.

[0017] Optionally, the first rotary drive and the support base are fixedly connected; the spacing adjustment member is connected to the second rotary drive and is used to drive the second rotary drive to move the second roller laterally relative to the first roller.

[0018] Optionally, the spacing adjustment component includes: a spring mounting base, which is fixedly connected to the support base and screwed onto one end of a bolt; an adjustment bracket, the fixed end of which is rotatably connected to the support base, and the movable end of which is screwed onto the other end of the bolt; a second rotary actuator connected to the adjustment bracket and between the fixed end and the movable end of the adjustment bracket; and a spring sleeved on the outer periphery of the bolt and located between the spring mounting base and the adjustment bracket. In actual use, rotating the bolt adjusts the lateral spacing between the movable end of the spring mounting base and the adjustment bracket. The fixed end of the adjustment bracket drives the second rotary actuator to rotate around a first axis, thereby adjusting the lateral spacing between the second rotary actuator and the first rotary actuator, and consequently adjusting the lateral spacing between the second roller and the first roller. Thus, the lateral spacing between the second roller and the first roller can be easily adjusted by rotating the bolt. The spring is used to improve the connection stability between the spring mounting base and the adjustment bracket.

[0019] Optionally, the anchor cable delivery mechanism further includes an anchor cable conduit, which extends vertically and is located below the anchor cable pushing assembly for delivering the anchor cable to the anchor cable pushing assembly and facilitating the guidance of the anchor cable into the space between the first roller and the second roller.

[0023] Optionally, the anchor cable mixing mechanism includes a mixing hydraulic motor fixed to the support base. The output end of the mixing hydraulic motor is provided with an anchor cable connector, which is used to connect to the cut end of the anchor cable.

The fastener includes two symmetrical fastening components. The two fastening components are used to fit around the outer periphery of the cut end of the anchor cable and drive the cut end of the anchor cable into the cavity of the sleeve. After the cut end of the anchor cable is inserted into the sleeve, the two fastening components are fitted around the outer periphery of the anchor cable and inserted into the cavity of the sleeve to fix the cut end of the anchor cable inside the sleeve. As can be seen from the above, the structure of this anchor cable joint is simple, and it can easily realize the detachable fixed connection of the anchor cable to the output end of the stirring hydraulic motor, and facilitate the installation and removal of the cut end of the anchor cable and the output end of the stirring hydraulic motor.

[0025] Secondly, the present invention also provides a construction method for an anchor cable construction device, comprising the following steps:

[0028] S3. The anchor cable stirring mechanism is connected to the cut end of the anchor cable and drives the anchor cable to stir in the borehole.

[0029] (III) Beneficial Effects

[0030] The beneficial effects of this invention are:

[0031] The anchor cable construction device of the present invention comprises an anchoring agent delivery mechanism that delivers anchoring agent into the borehole, an anchor cable delivery mechanism that delivers the anchor cable into the borehole filled with the anchoring agent, and an anchor cable that is cut. An anchor cable mixing mechanism is connected to the cut end of the anchor cable and is used to stir the anchor cable within the borehole to ensure uniform mixing of the anchoring agent. Thus, the anchor cable construction device, through the anchoring agent delivery mechanism, the anchor cable delivery mechanism, and the anchor cable mixing mechanism, achieves fully automated mechanized construction of the anchor cable installation process (anchoring agent delivery process, anchor cable delivery process, and anchor cable mixing process) for a single anchor cable, thereby improving construction efficiency, replacing manual construction, and avoiding the problems of high labor intensity and dangerous working environments associated with manual construction.

[0032] Furthermore, the anchor cable construction device of this embodiment also has the following advantages:

[0033] First, the anchoring agent delivery mechanism includes anchoring agent delivery components and installation components.

[0034] The anchoring agent delivery component is height-adjustable, facilitating its movement into the borehole and delivery of the anchoring agent. The discharge pipe and installation pipe within the anchoring agent delivery component are detachably connected, allowing for the replacement of discharge pipes with different inner diameters and adaptability to different types of anchoring agents and boreholes of varying diameters. The anchoring agent delivery component is detachably fixed to the support base via an installation component for easy loading and unloading. Movable parts within the installation component are fixedly connected to drive the installation pipe in a lifting motion. As can be seen, this anchoring agent delivery mechanism has a simple structure and is easy to manufacture and install / unload.

[0035] Second, the anchor cable delivery mechanism includes an anchor cable pushing component and an anchor cable shearing component.

[0036] The anchor cable pushing assembly is used to push the anchor cable upwards. The anchor cable cutting assembly is located above the anchor cable pushing assembly. The anchor cable cutting assembly receives the anchor cable pushed upwards by the anchor cable pushing assembly, guides the anchor cable into the borehole, and cuts the anchor cable when it reaches a set length. This enables fully automated anchor cable delivery.

[0037] The first and second clamping components in the anchor cable pushing assembly are used to clamp and feed the anchor cable. The first and second clamping components rotate in opposite directions to drive the anchor cable upwards, facilitating automatic anchor cable delivery. The first and second clamping components are configured with adjustable lateral spacing to allow them to clamp anchor cables of different diameters. A spacing adjustment component in the anchor cable pushing assembly is used to adjust the lateral spacing between the first and second clamping components. This component includes a spring mounting base, an adjusting bracket, and a spring. The lateral spacing between the second and first rollers can be easily adjusted by rotating a bolt. The spring also improves the connection stability between the spring mounting base and the adjusting bracket. Furthermore, this anchor cable pushing assembly has a simple structure, small size, and facilitates automatic anchor cable delivery.

[0038] The anchor cable cutting assembly includes a cutting housing, a first shear, and a second shear. The cutting housing is fixedly connected to a support base and has a vertically penetrating channel inside. The first and second shears can selectively extend into the channel and close to cut the anchor cable. As can be seen, this anchor cable cutting assembly has a simple structure, small size, and can conveniently deliver the anchor cable into the borehole and cut it. The bottom of the cutting housing extends vertically to form a cutting guide tube, which communicates with the channel. The cutting guide tube receives the anchor cable pushed by the anchor cable pushing assembly to guide the movement of the anchor cable.

[0039] The anchor cable guide in the anchor cable delivery mechanism extends vertically and is located below the anchor cable pushing assembly. It is used to guide and deliver the anchor cable to the anchor cable pushing assembly and facilitates the guidance and delivery of the anchor cable between the first roller and the second roller.

[0040] Third, the hydraulic motor in the anchor cable mixing mechanism drives the anchor cable to mix inside the borehole through the anchor cable joint, so as to make the anchoring agent evenly mixed.

[0041] The anchor cable joint includes a sleeve and fasteners. After the cut end of the anchor cable is inserted into the sleeve, two fasteners are fitted around the outer circumference of the anchor cable and inserted into the cavity of the sleeve to fix the cut end of the anchor cable inside the sleeve. After mixing is complete, the fasteners can be pulled out of the sleeve to separate the cut end of the anchor cable from the sleeve. As can be seen from the above, this anchor cable joint has a simple structure and can easily achieve detachable connection of the anchor cable to the output end of the mixing hydraulic motor, and facilitates the installation and removal of the anchor cable joint and the output end of the mixing hydraulic motor.

[0051] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0052] Example 1

[0053] See Figure 1-4 An anchor cable construction device proposed in this embodiment of the invention includes a support base 1, an anchoring agent delivery mechanism 2, an anchor cable delivery mechanism 3, and an anchor cable mixing mechanism 4, all of which are connected to the support base 1.

[0054] The anchoring agent delivery mechanism 2 is used to deliver the anchoring agent into the borehole. The anchor cable delivery mechanism 3 is used to deliver the anchor cable into the borehole filled with anchoring agent and to cut the anchor cable. The anchor cable mixing mechanism 4 is connected to the cut end of the anchor cable and drives the anchor cable to mix in the borehole to ensure that the anchoring agent is mixed evenly.

[0055] Specifically, the construction method of the anchor cable construction device in this embodiment includes the following steps:

[0056] S1. The anchoring agent is delivered into the borehole through the anchoring agent delivery mechanism 2.

[0057] S2. The anchor cable is fed into the borehole filled with anchoring agent through the anchor cable conveying mechanism 3, and the anchor cable is cut when it is conveyed to the set length.

[0058] S3, the anchor cable mixing mechanism 4 is connected to the cut end of the anchor cable and drives the anchor cable to mix inside the borehole.

[0059] Therefore, the anchor cable construction device in this embodiment realizes fully automated mechanized construction of the anchor cable installation process (anchoring agent delivery process, anchor cable delivery process, and anchor cable mixing process) of a single anchor cable through the anchoring agent delivery mechanism, the anchor cable delivery mechanism, and the anchor cable mixing mechanism, so as to improve construction efficiency, replace manual construction, and avoid the problems of high labor intensity and dangerous working environment and safety hazards of manual construction.

[0060] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0061] Specifically, the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 are all movable relative to the support base 1 to facilitate adjustment of the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 to the corresponding borehole. For example, the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 are all rotatably connected to the support base 1 via a support frame.

[0062] Alternatively, the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 are all fixedly connected to the support base 1 to simplify the structure and facilitate processing and loading / unloading.

[0063] Since the diameter of the single anchor cable transported by the anchor cable construction device in this embodiment is relatively small, about 15-22mm, while the diameter of the drill hole is relatively large, about 30-32mm, after the anchoring agent is transported into the drill hole, the anchor cable transport mechanism 3 only needs to correspond to the drill hole and be able to send the anchor cable into the drill hole; it is not necessary to precisely align the anchor cable and the drill hole. Moreover, since the anchor cable is made of flexible material, workers can assist in bending the anchor cable and sending it into the hole. Therefore, in this embodiment, the anchoring agent transport mechanism 2, the anchor cable transport mechanism 3, and the anchor cable mixing mechanism 4 are all set to be fixedly connected to the support base 1 to simplify the structure and facilitate processing and loading / unloading.

[0064] Specifically, the anchoring agent delivery mechanism 2 is located on the first side of the support base 1, and the anchor cable delivery mechanism 3 and the anchor cable mixing mechanism 4 are both located on the second side of the support base 1 and are arranged adjacent to each other, so as to reduce the overall volume of the anchor cable construction device and facilitate the delivery of the anchor cable construction device of this embodiment into the coal mine or tunnel, and facilitate the connection of the cut end of the anchor cable to the anchor cable mixing mechanism 4 after the anchor cable is cut.

[0065] Furthermore, the anchoring agent delivery mechanism 2 includes an anchoring agent delivery component 22.

[0066] The anchoring agent delivery component 22 is vertically and flexibly connected to the support base 1. The anchoring agent delivery component 22 is used to deliver anchoring agent into the borehole. The vertically and flexibly configured anchoring agent delivery component 22 facilitates its movement into the borehole and delivery of anchoring agent into the borehole.

[0067] Preferably, the end of the anchoring agent delivery component 22 is beveled to facilitate the delivery of anchoring agent into the borehole.

[0068] Specifically, the anchoring agent delivery mechanism 2 also includes an air pipe and a tee connector. The air pipe is connected to the anchoring agent delivery component 22. The tee connector is connected to the air pipe, with one connector for connecting to an external air supply component and the other connector for supplying the anchoring agent. In actual use, the air supply component can sequentially blow the anchoring agent through the air pipe and the anchoring agent delivery mechanism 2 into the borehole to achieve automatic delivery of the anchoring agent. The air supply component is preferably an air pump, but other gas delivery mechanisms can also be used. Of course, in this embodiment, the air pipe and the three-way connector are used to blow the anchoring agent, but the present invention is not limited to this. The power to deliver the anchoring agent does not necessarily come from gas. It can also be mechanical pushing. For example, an anchoring agent storage device is set up to store the anchoring agent. The anchoring agent storage device and the anchoring agent conveying device 22 are connected. A pushing rod is set in the anchoring agent storage device. The pushing rod can extend and retract between the anchoring agent storage device and the anchoring agent conveying device 22 to deliver the anchoring agent into the anchoring agent conveying device 22 and then into the borehole.

[0069] Specifically, the anchoring agent delivery mechanism 2 also includes a mounting member 21. The mounting member 21 is used to vertically connect the anchoring agent delivery member 22 to the support base 1.

[0070] Mounting component 21 includes a fixed part 211 and a movable part 212 that can be raised and lowered relative to the fixed part 211. The fixed part 211 is fixedly connected to the support base 1. The movable part 212 moves up and down relative to the fixed part 211 to facilitate the raising and lowering of the anchoring agent delivery component 22 into the borehole.

[0071] Specifically, the fixing part 211 is detachably fixed to the mounting base 213 and the support base 1 for easy installation and removal. The mounting base 213 and the support base 1 are preferably connected by bolts.

[0072] Preferably, the mounting part 21 is a hydraulic cylinder, the movable part 212 is the cylinder body of the hydraulic cylinder, and the movable part 212 is the piston of the hydraulic cylinder; or, the fixed part 211 is a lead screw, and the movable part 212 is a nut sleeved on the lead screw and moving up and down along the lead screw; or, the fixed part 211 is a vertically arranged slide rail, and the movable part 212 is a slider slidably arranged on the slide rail; of course, the fixed part 211 and the movable part 212 can also be arranged in other ways, as long as the function of the movable part 212 moving up and down relative to the fixed part 211 is satisfied.

[0073] Specifically, the anchoring agent delivery component 22 includes an installation pipe 221 and a discharge pipe 222.

[0074] The movable part 212 and the mounting pipe 221 are fixedly connected to drive the mounting pipe 221 to rise and fall. The discharge pipe 222 is detachably connected to the mounting pipe 221 and the discharge pipe 222 and the mounting pipe 221 are connected. When the movable part 212 drives the mounting pipe 221 to rise and fall, the mounting pipe 221 drives the discharge pipe 222 to rise and fall synchronously. The discharge pipe 222 is used to extend into the borehole to deliver the anchoring agent into the borehole. The inclined surface of the anchoring agent delivery part 22 is located at the end of the discharge pipe 222. The discharge pipe 222 is detachably connected to the mounting pipe 221 to facilitate the replacement of discharge pipes 222 with different inner diameters, and it is applicable to different types of anchoring agents and boreholes with different diameters, thus expanding the applicability of the anchor cable construction device of this embodiment.

[0075] Specifically, the movable part 212 and the mounting tube 221 are fixedly connected by a connecting rod 23. The connecting rod is Z-shaped, with one end sleeved and fixed to the outer periphery of the movable part 212 through a cylindrical body, and the other end sleeved and fixed to the outer periphery of the mounting tube 221 through another cylindrical body. Preferably, the cylindrical bodies are detachably connected to both the movable part 212 and the mounting tube 221 for easy installation, removal, and maintenance.

[0076] As can be seen from the above, the anchoring agent delivery mechanism 2 in this embodiment has a simple structure and is easy to process and load / unload.

[0077] Furthermore, the anchor cable delivery mechanism 3 includes an anchor cable pushing assembly 31 and an anchor cable cutting assembly 32.

[0078] Both the anchor cable pushing assembly 31 and the anchor cable cutting assembly 32 are fixedly connected to the support base 1. The anchor cable pushing assembly 31 is used to push the anchor cable upward. The anchor cable cutting assembly 32 is located above the anchor cable pushing assembly 31; the anchor cable cutting assembly 32 is used to receive the anchor cable pushed upward by the anchor cable pushing assembly 31 and guide the anchor cable into the borehole, and to cut the anchor cable when it is delivered to a set length, so as to realize the automatic delivery and cutting of the anchor cable.

[0079] Specifically, the anchor cable pushing assembly 31 includes a first clamping component and a second clamping component.

[0080] The first and second clamping members are rotatably connected to the support base 1, and their lateral spacing is adjustable. The first and second clamping members are used to clamp and feed anchor cables, and they rotate in opposite directions to drive the anchor cables upwards, facilitating automatic anchor cable feeding. The first and second clamping members are configured with an adjustable lateral spacing to allow them to clamp anchor cables of different diameters. It should be noted that the lateral spacing described herein includes both horizontal spacing and spacing with a horizontal component.

[0081] Specifically, the first clamping element is a first roller 3112, and the second clamping element is a second roller 3123. The anchor cable pushing assembly 31 also includes a first rotary driver 3111 and a second rotary driver 3122.

[0082] The output end of the first rotary driver 3111 is fixedly connected to the first roller 3112, and the output end of the second rotary driver 3122 is fixedly connected to the second roller 3123. The first rotary driver 3111 is used to drive the first roller 3112 to rotate, and the second rotary driver 3122 is used to drive the second roller 3123 to rotate, and the first roller 3112 and the second roller 3123 rotate in opposite directions, thereby driving the anchor cable clamped by them to be conveyed upward.

[0083] Specifically, the anchor cable pushing assembly 31 also includes a spacing adjustment element 3121.

[0084] The spacing adjustment member 3121 is connected to the first rotary driver 3111 and / or the second rotary driver 3122, and is used to drive the first rotary driver 3111 and / or the second rotary driver 3122 to move laterally to adjust the lateral spacing between them, thereby adjusting the lateral spacing between the first clamping member and the second clamping member connected to them.

[0085] Specifically, there are three ways to adjust the lateral spacing between the first and second clamping parts:

[0086] The first configuration is as follows: the first rotary driver 3111 is fixedly connected to the support base 1, and the spacing adjustment component 3121 is connected to the second rotary driver 3122 to drive the second rotary driver 3122 to drive the second roller 3123 to move laterally relative to the first roller 3112.

[0087] The second configuration is as follows: the second rotary driver 3122 is fixedly connected to the support base 1, and the spacing adjustment component 3121 is connected to the first rotary driver 3111 to drive the first rotary driver 3111 to move the first roller 3112 laterally relative to the second roller 3123.

[0088] The third configuration is as follows: the spacing adjustment component 3121 is connected to the first rotary driver 3111 and the second rotary driver 3122. The spacing adjustment component 3121 is used to drive the first rotary driver 3111 to move the first roller 3112 laterally, and to drive the second rotary driver 3122 to move the second roller 3123 laterally.

[0089] Specifically, when the adjustable lateral spacing between the first clamping component and the second clamping component is set in the first mode (in this embodiment...), Figure 1 When (as shown):

[0090] Reference Figure 1 As shown, the structure of the spacing adjustment component 3121 includes a spring mounting base 31211, an adjustment bracket 31212, and a spring 31213.

[0091] Spring mounting base 31211 is fixedly connected to support base 1 and sleeved on one end of bolt 31215. The fixed end of adjusting bracket 31212 is rotatably connected to support base 1, and the movable end of adjusting bracket 31212 is screwed to the other end of bolt 31215. Second rotary drive 3122 is connected to adjusting bracket 31212 and is connected between the fixed end and the movable end of adjusting bracket 31212. Spring 31213 is sleeved on the outer periphery of bolt 31215 and located between spring mounting base 31211 and adjusting bracket 31212.

[0092] Specifically, the fixed end of the adjusting bracket 31212 rotates around the first axis.

[0093] In practical use, rotating the bolt 31215 adjusts the lateral distance between the movable ends of the spring mounting base 31211 and the adjusting bracket 31212. The fixed end of the adjusting bracket 31212 drives the second rotary actuator 3122 to rotate around the first axis, thereby adjusting the lateral distance between the second rotary actuator 3122 and the first rotary actuator 3111, and consequently adjusting the lateral distance between the second roller 3123 and the first roller 3112. Thus, the lateral distance between the second roller 3123 and the first roller 3112 can be easily adjusted by rotating the bolt 31215. Furthermore, the spacing adjustment component 3121 in this embodiment has a simple structure, small size, and is easy to manufacture. The spring 31213 is used to improve the connection stability between the spring mounting base 31211 and the adjusting bracket 31212.

[0094] The spacing adjustment component 3121 can also be a cylinder fixedly connected to the support base 1, with the output end of the cylinder horizontally positioned and fixedly connected to the second rotary driver 3122. In actual use, the cylinder drives the second rotary driver 3122 to move laterally, thereby adjusting the lateral spacing between the second roller 3123 and the first roller 3112 accordingly.

[0095] The spacing adjustment component 3121 can also be a slide rail fixed to the support base 1. The slide rail is horizontally positioned and fitted with a belt. Both ends of the belt are fitted onto gears, which are fixed to a motor. The second rotary driver 3122 is fixed to the belt via a slider. In actual use, the motor drives the belt to rotate around the gears, the belt drives the slider to move laterally, and the slider drives the second rotary driver 3122 to move laterally, thereby adjusting the lateral spacing between the second roller 3123 and the first roller 3112 accordingly.

[0096] The spacing adjustment component 3121 can also be a lead screw fixed to the support base 1. The lead screw is fixed to the output end of the motor, and the lead screw is horizontally set and fitted with a lead screw nut. The lead screw nut is fixed to the second rotary drive 3122. In actual use, the motor drives the lead screw to rotate, and the lead screw nut drives the second rotary drive 3122 to move laterally, so as to adjust the lateral spacing between the second roller 3123 and the first roller 3112 accordingly.

[0097] When the adjustable lateral spacing between the first and second clamping parts is set to the second method:

[0098] The structure of the spacing adjustment component 3121 includes a spring mounting base 31211, an adjustment bracket 31212, and a spring 31213.

[0099] Spring mounting base 31211 is fixedly connected to support base 1 and sleeved on one end of bolt 31215. The fixed end of adjusting bracket 31212 is rotatably connected to support base 1, and the movable end of adjusting bracket 31212 is screwed to the other end of bolt 31215. First rotary drive 3111 is connected to adjusting bracket 31212 and is located between the fixed end and the movable end of adjusting bracket 31212. Spring 31213 is sleeved on the outer periphery of bolt 31215 and located between spring mounting base 31211 and adjusting bracket 31212.

[0100] Specifically, the fixed end of the adjusting bracket 31212 rotates around the first axis.

[0101] In practical use, rotating bolt 31215 adjusts the lateral distance between the movable ends of spring mounting base 31211 and adjusting bracket 31212. The fixed end of adjusting bracket 31212 drives the first rotary actuator 3111 to rotate around the first axis, thereby adjusting the lateral distance between the first rotary actuator 3111 and the second rotary actuator 3122, and consequently adjusting the lateral distance between the first roller 3112 and the second roller 3123. Thus, the lateral distance between the first roller 3112 and the second roller 3123 can be easily adjusted by rotating bolt 31215. Spring 31213 is used to improve the connection stability between spring mounting base 31211 and adjusting bracket 31212.

[0102] The spacing adjustment component 3121 can also be a cylinder fixedly connected to the support base 1, with the output end of the cylinder horizontally positioned and fixedly connected to the first rotary driver 3111. In actual use, the cylinder drives the first rotary driver 3111 to move laterally, thereby adjusting the lateral spacing between the first roller 3112 and the second roller 3123 accordingly.

[0103] The spacing adjustment component 3121 can also be a slide rail fixed to the support base 1. The slide rail is horizontally positioned and fitted with a belt. Both ends of the belt are fitted onto gears, which are fixed to a motor. The first rotary driver 3111 is fixed to the belt via a slider. In actual use, the motor drives the belt to rotate around the gears, the belt drives the slider to move laterally, and the slider drives the first rotary driver 3111 to move laterally, thereby adjusting the lateral spacing between the first roller 3112 and the second roller 3123 accordingly.

[0104] The spacing adjustment component 3121 can also be a lead screw fixed to the support base 1. The lead screw is fixed to the output end of the motor, and the lead screw is horizontally set and fitted with a lead screw nut. The lead screw nut is fixed to the first rotary driver 3111. In actual use, the motor drives the lead screw to rotate, and the lead screw nut drives the first rotary driver 3111 to move laterally, so as to adjust the lateral spacing between the first roller 3112 and the second roller 3123 accordingly.

[0105] When the lateral spacing between the first clamping component and the second clamping component is adjustable in the third manner, two spacing adjustment components 3121 are provided.

[0106] The structure of the two pitch adjustment components 3121 can be as follows: each pitch adjustment component 3121 includes a spring mounting base 31211, an adjustment bracket 31212, and a spring 31213. The spring mounting base 31211 is fixedly connected to the support base 1 and sleeved on one end of a bolt 31215. The fixed end of the adjustment bracket 31212 is rotatably connected to the support base 1, and the movable end of the adjustment bracket 31212 is screwed to the other end of the bolt 31215. A first rotary actuator 3111 is connected to the adjustment bracket 31212 and is connected between the fixed end and the movable end of one of the adjustment brackets 31212. A second rotary actuator 3122 is connected to the adjustment bracket 31212 and is connected between the fixed end and the movable end of the other adjustment bracket 31212. The spring 31213 is sleeved on the outer periphery of the bolt 31215 and is located between the spring mounting base 31211 and the adjustment bracket 31212.

[0107] Specifically, the fixed end of the adjusting bracket 31212 rotates around the first axis.

[0108] In practical use, rotating bolt 31215 adjusts the lateral distance between the movable ends of spring mounting base 31211 and adjusting bracket 31212. The fixed end of one adjusting bracket 31212 drives the first rotary actuator 3111 to rotate around the first axis, and the fixed end of the other adjusting bracket 31212 drives the second rotary actuator 3122 to rotate around the first axis, thereby adjusting the lateral distance between the first rotary actuator 3111 and the second rotary actuator 3122, and consequently, the lateral distance between the first roller 3112 and the second roller 3123. Thus, adjusting the lateral distance between the first roller 3112 and the second roller 3123 can be conveniently achieved by rotating bolt 31215. Spring 31213 is used to improve the connection stability between spring mounting base 31211 and adjusting bracket 31212.

[0109] The two spacing adjustment components 3121 can also be: each spacing adjustment component 3121 is a cylinder fixedly connected to the support base 1, and the output ends of the two cylinders are horizontally arranged and correspondingly fixedly connected to the first rotary driver 3111 and the second rotary driver 3122. In actual use, the two cylinders drive the first rotary driver 3111 and the second rotary driver 3122 to move laterally, so as to adjust the lateral spacing of the first roller 3112 and the second roller 3123 accordingly.

[0110] The spacing adjustment component 3121 can also be: each spacing adjustment component 3121 is a slide rail fixed to the support base 1, the two slide rails are horizontally arranged and fitted with belts, the two ends of the belts are fitted onto gears, the gears are fixed to a motor, and the first rotary driver 3111 and the second rotary driver 3122 are respectively fixed to the two belts through sliders. In actual use, the motor drives the belt to rotate around the gears, the belt drives the sliders to move laterally, and the two sliders respectively drive the first rotary driver 3111 and the second rotary driver 3122 to move laterally, so as to adjust the lateral spacing of the first roller 3112 and the second roller 3123 accordingly.

[0111] The spacing adjustment component 3121 can also be: each spacing adjustment component 3121 is a lead screw fixedly connected to the support base 1, the lead screw is fixedly connected to the output end of the motor, and the lead screw is horizontally set and fitted with a lead screw nut. The two lead screw nuts are respectively fixedly connected to the first rotary driver 3111 and the second rotary driver 3122. In actual use, the motor drives the lead screw to rotate, and the two lead screw nuts drive the first rotary driver 3111 and the second rotary driver 3122 to move laterally, so as to adjust the lateral spacing of the first roller 3112 and the second roller 3123 accordingly.

[0112] It should be noted that if the spacing adjustment component 3121 includes a spring mounting base 31211, an adjustment bracket 31212, and a spring 31213: when the first rotary driver 3111 drives the first roller 3112 to rotate around the first axis and / or the second rotary driver 3122 drives the second roller 3123 to rotate around the first axis, the first roller 3112 and / or the second roller 3123 will move up and down, resulting in a height difference between them. That is, the "lateral spacing" is not a pure horizontal spacing, but a spacing that includes both horizontal and vertical components. However, the anchor cable clamped by the first roller 3112 and / or the second roller 3123 is a single anchor cable with a diameter range of 15-22mm and a small deviation. Only a slight adjustment of the lateral distance between the second roller 3123 and the first roller 3112 is needed to clamp single anchor cables of different diameters. Therefore, even if there is a height difference in the lifting and lowering movement of the first roller 3112 and / or the second roller 3123, it will not affect the clamping of the anchor cable.

[0113] Specifically, both the first rotary drive 3111 and the second rotary drive 3122 are components with rotary drive function, such as hydraulic motors or reducers. Preferably, both the first rotary drive 3111 and the second rotary drive 3122 are hydraulic motors.

[0114] Preferably, the fixed end of the adjusting bracket 31212 is rotatably connected to the support base 1 via a pin 31214, and the axis of the pin 31214 is the first axis.

[0115] As can be seen from the above, the anchor cable pushing component 31 of this embodiment has a simple structure, small size, and can conveniently realize the automatic transmission of anchor cables.

[0116] Specifically, the anchor cable shearing assembly 32 includes a shearing housing 321 and a shearing member located inside the shearing housing 321.

[0117] The shear housing 321 is fixedly connected to the support base 1 and has a vertically penetrating channel 3211 inside. The shearing component includes a first shear and a second shear, which can selectively extend into the channel 3211 and close to cut the anchor cable.

[0118] In practical use, the anchor cable pushed upward by the anchor cable pushing component 31 enters the channel 3211 of the anchor cable cutting component 32, and is then conveyed into the borehole from the top of the anchor cable cutting component 32. When the anchor cable has been conveyed to a set length, the first and second shears can selectively extend into the channel 3211 and close to cut the anchor cable, thus completing the conveying of the anchor cable. As can be seen from the above, this anchor cable cutting component 32 has a simple structure, small size, and can conveniently convey the anchor cable into the borehole and cut the anchor cable.

[0119] In this embodiment, see Figure 3 As shown, the first and second shears are a fixed shear 322 and a telescopic shear 323, respectively. The fixed shear 322 is fixed inside the shear housing 321 and extends into the channel 3211. The telescopic shear 323 is movably disposed within the shear housing 321 and can selectively extend into the channel 3211, and is positioned opposite to and vertically aligned with the fixed shear 322. The telescopic shear 323 moves left and right while the fixed shear 322 closes to cooperate in cutting the anchor cable.

[0120] Alternatively, in other embodiments, both the first and second shears are telescopic shears 323. The telescopic shears 323 are movably disposed within the shearing housing 321 and can selectively extend into the channel 3211. The two telescopic shears 323 are positioned opposite each other and vertically. The two telescopic shears 323 move left and right until they are closed to cooperate in cutting the anchor cable.

[0121] Specifically, when the first shear is a fixed shear 322 and the second shear is a telescopic shear 323, the anchor cable cutting assembly 32 also includes a telescopic shear drive.

[0122] The telescopic shear drive includes a telescopic shear fixing part 324 and a telescopic shear movable part 325. The telescopic shear fixing part 324 is fixedly connected to the inner wall of the shear housing 321. The telescopic shear movable part 325 is slidably connected to the telescopic shear fixing part 324, and is fixedly connected to the telescopic shear 323 to drive the telescopic shear 323 to move left and right. Preferably, the telescopic shear drive is a hydraulic cylinder, with the telescopic shear fixing part 324 being the cylinder body of the hydraulic cylinder and the telescopic shear movable part 325 being the piston of the hydraulic cylinder; or, the telescopic shear fixing part 324 is a horizontally arranged lead screw, and the telescopic shear movable part 325 is a nut sleeved on the lead screw and moving left and right along the lead screw; or, the telescopic shear fixing part 324 is a horizontally arranged slide rail, and the telescopic shear movable part 325 is a slider slidably arranged on the slide rail; of course, the telescopic shear fixing part 324 and the telescopic shear movable part 325 can also be arranged in other ways, as long as the function of the telescopic shear movable part 325 moving left and right relative to the telescopic shear fixing part 324 is satisfied.

[0123] Specifically, when both the first and second shears are telescopic shears 323, the anchor cable shear assembly 32 also includes two telescopic shear drives.

[0124] Both telescopic shear drive components include a telescopic shear fixing part 324 and a telescopic shear movable part 325. The telescopic shear fixing part 324 is fixedly connected to the inner wall of the shear housing 321. The telescopic shear movable part 325 is slidably connected to the telescopic shear fixing part 324, and the two telescopic shear movable parts 325 are correspondingly fixedly connected to the two telescopic shears 323 to drive the two telescopic shears 323 to move left and right to close, so as to cooperate in cutting the anchor cable. Preferably, the telescopic shear drive is a hydraulic cylinder, the telescopic shear fixing part 324 is the cylinder body of the hydraulic cylinder, and the telescopic shear movable part 325 is the piston of the hydraulic cylinder; or, the telescopic shear fixing part 324 is a horizontally arranged lead screw, and the telescopic shear movable part 325 is a nut sleeved on the lead screw and moving left and right along the lead screw; or, the telescopic shear fixing part 324 is a horizontally arranged slide rail, and the telescopic shear movable part 325 is a slider slidably arranged on the slide rail; of course, the telescopic shear fixing part 324 and the telescopic shear movable part 325 can also be arranged in other ways, as long as the function of the telescopic shear movable part 325 moving left and right relative to the telescopic shear fixing part 324 is satisfied.

[0125] Specifically, both the first and second cuts are arc-shaped, or both the first and second cuts are thin slices.

[0126] It should be noted that in other embodiments, the shearing element may also include a rotary actuator, a gear, and a blade.

[0127] At this time, the rotary actuator is fixed to the top or bottom of the inner wall of the shearing housing 321. The output end of the rotary actuator is vertically arranged and fixed to the gear, and at least one blade is fixed to the circumference of the gear. In actual use, when it is necessary to cut the anchor cable, the rotary actuator drives the gear to rotate, the gear drives the blade to rotate synchronously, and the blade contacts and cuts the anchor cable. Preferably, three blades are arranged at circumferential intervals on the gear to facilitate cutting the anchor cable. When the anchor cable is fed into the borehole, the blades on the circumferential direction of the gear move away from the anchor cable. Preferably, the shearing component also includes a rotary actuator moving component, which is fixed to the inner wall of the shearing housing 321 and fixed to the rotary actuator. The rotary actuator moving component is used to drive the rotary actuator to move laterally, so that when the anchor cable is fed, the rotary actuator can drive the gear and blade away from the anchor cable, and when the anchor cable is cut, the rotary actuator can drive the gear and blade to move to fit against the anchor cable. Preferably, the rotary actuator moving component is a cylinder, and the rotary actuator is a motor.

[0128] Preferably, a sensor is provided at the top or bottom of the shear housing 321 to monitor the delivery length of the anchor cable so as to cut the anchor cable in a timely manner when the anchor cable is delivered to a set length.

[0129] Specifically, the bottom of the shear housing 321 extends vertically to form a shear conduit 3212, which is connected to the channel 3211. The shear conduit 3212 is used to receive the anchor cable pushed by the anchor cable push assembly 31 to guide the movement of the anchor cable.

[0130] Specifically, the anchor cable shearing assembly 32 also includes a clamping plate 326 and a mounting plate 327.

[0131] Mounting plate 327 is fixedly connected to support base 1 and detachably connected to clamping plate 326, preferably by bolts. Mounting plate 327 and clamping plate 326 can form a cavity for clamping shear shell 321 to fix shear shell 321 to support base 1. The structure is simple and easy to install and remove.

[0132] Furthermore, the anchor cable delivery mechanism 3 also includes an anchor cable conduit 33.

[0133] The anchor cable conduit 33 extends vertically and is located below the anchor cable pushing assembly 31, specifically below the first roller 3112 and the second roller 3123. The anchor cable conduit 33 is used to deliver the anchor cable to the anchor cable pushing assembly 31 and facilitates guiding the anchor cable between the first roller 3112 and the second roller 3123.

[0134] In practical use, anchor cables are automatically fed into the anchor cable conduit 33 via an anchor cable reel, or manually assisted. It is preferable to use an automatic anchor cable reel to feed the anchor cable into the anchor cable conduit 33 to improve the efficiency of anchor cable delivery.

[0135] Specifically, the anchor cable conduit 33 is fixed to the support base 1 via the conduit mounting plate 331.

[0136] Furthermore, the anchor cable mixing mechanism 4 includes a mixing hydraulic motor 41 fixedly connected to the support base 1. The output end of the mixing hydraulic motor 41 is provided with an anchor cable joint 42, which is used to connect to the cut end of the anchor cable. The mixing hydraulic motor 41 drives the anchor cable to mix in the borehole through the anchor cable joint 42, so as to make the anchoring agent evenly mixed.

[0137] Specifically, the stirring hydraulic motor 41 is detachably fixed to the support base 1 via the stirring mounting plate 43, so as to facilitate the installation, removal and maintenance of the stirring hydraulic motor 41.

[0138] Specifically, the anchor cable joint 42 includes a sleeve 421 and a fastener 422.

[0139] The sleeve 421 is cylindrical and is fitted onto the output end of the anchor cable mixing mechanism 4, which is also the output end of the mixing hydraulic motor 41. The through hole on the side wall of the sleeve 421 corresponds to the through hole on the output end of the mixing hydraulic motor 41 and is detachably fixed together by a pin. After the cut end of the anchor cable is inserted into the sleeve 421, the fastener 422 is used to fix the cut end of the anchor cable inside the sleeve 421.

[0140] Fastener 422 is a truncated cone extending from front to back. The maximum diameter of the truncated cone is equal to or greater than the inner diameter of sleeve 421. Fastener 422 includes two symmetrical fastening components 4221. After the cut end of the anchor cable is inserted into sleeve 421, the two fastening components 4221 are fitted around the outer circumference of the anchor cable and inserted into the cavity of sleeve 421 to fix the cut end of the anchor cable inside sleeve 421. After mixing is complete, fastener 422 can be pulled out of sleeve 421 to separate the cut end of the anchor cable from sleeve 421.

[0141] As can be seen from the above, the anchor cable joint 42 has a simple structure and can easily detachably connect the anchor cable to the output end of the mixing hydraulic motor 41, and facilitates the installation and removal of the cut end of the anchor cable and the output end of the mixing hydraulic motor 41.

[0142] Furthermore, for better explanation, the operation method of the anchor cable construction device in this embodiment is as follows:

[0143] S11: The movable part 212 of the mounting part 21 drives the anchoring agent conveying part 22 to rise, so as to drive the discharge pipe 222 of the anchoring agent conveying part 22 to extend into the borehole and deliver the anchoring agent into the borehole. After the anchoring agent is delivered, the movable part 212 drives the anchoring agent conveying part 22 to fall, so as to drive the discharge pipe 222 to leave the borehole.

[0144] S12: Anchor cable is delivered into the anchor cable conduit 33. The anchor cable moves upward and enters between the first roller 3112 and the second roller 3123 of the anchor cable pushing assembly 31. The first rotary driver 3111 drives the first roller 3112 to rotate, and the second rotary driver 3122 drives the second roller 3123 to rotate. The first roller 3112 and the second roller 3123 rotate in opposite directions and drive the anchor cable held by them to be conveyed upward.

[0145] S13: The anchor cable, conveyed upward by the first roller 3112 and the second roller 3123, enters the anchor cable cutting assembly 32. The anchor cable enters the channel 3211 of the shear housing 321 through the shearing guide 3212 at the bottom of the shear housing 321 and is then conveyed into the borehole from the top of the shear housing 321. When the anchor cable is conveyed to the set length, the first rotary drive 3111 and the second rotary drive 3122 stop, the first roller 3112 and the second roller 3123 stop rotating, and the telescopic shear movable part 325 drives the telescopic shear 323 to move left and right. The left and right movement of the telescopic shear 323 and the closing of the fixed shear 322 cooperate to cut the anchor cable.

[0146] S14: The cut end of the anchor cable is detachably fixed to the output end of the hydraulic motor 41 through the anchor cable joint 42. The stirring hydraulic motor 41 drives the anchor cable to stir in the borehole through the anchor cable joint 42. After stirring is completed, the cut end of the anchor cable and the anchor cable joint 42 are separated.

[0147] As shown above, the anchor cable construction device of this embodiment can conveniently and quickly realize fully automatic construction of anchor cables, improving construction efficiency and accuracy. In addition, the anchor cable construction device of this embodiment also has the following advantages: simple structure, easy to process; each structure can be disassembled and connected, which is convenient for installation and maintenance; small size, which is convenient for being sent into the tunnel.

[0148] Example 2

[0149] This embodiment provides an anchor cable construction device, which further includes an anchor cable construction control unit based on embodiment 1. The anchor cable construction control unit is communicatively connected to the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4. The anchor cable construction control unit is used to control the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 to work together, and to control the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 to work in sequence, so as to automatically control the anchor cable construction device, thereby improving construction efficiency and construction accuracy.

[0150] Specifically, the anchor cable construction control unit includes a control console and multiple PLC controllers. The multiple PLC controllers are respectively installed in the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4. All the multiple PLC controllers are connected to the control console, and the control console controls the opening and closing of the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 through the multiple PLC controllers.

[0151] The control console can be set up outside the tunnel, allowing staff to receive information from the PLC controller in real time and optimizing the working environment for staff, thus preventing accidents while working in coal mines or tunnels.

[0152] Specifically, the anchor cable construction control unit also includes multiple sensors, which are respectively installed in the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4. All the sensors are connected to the control console. The sensors are used to monitor the working status of the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 and send the working status information to the control console in real time or at regular intervals. This allows for better monitoring of the operation of the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4, and enables timely maintenance when the anchoring agent delivery mechanism 2, the anchor cable delivery mechanism 3, and the anchor cable mixing mechanism 4 malfunction.

[0153] Furthermore, for better explanation, the operation method of the anchor cable construction device in this embodiment is as follows:

[0154] S11: The anchor cable construction control unit controls the movable part 212 of the installation component 21 to drive the anchoring agent delivery component 22 to rise, so as to drive the discharge pipe 222 of the anchoring agent delivery component 22 to extend into the borehole and deliver the anchoring agent into the borehole. After the anchoring agent delivery is completed, the anchor cable construction control unit controls the movable part 212 to drive the anchoring agent delivery component 22 to fall, so as to drive the discharge pipe 222 to leave the borehole.

[0155] S12: Anchor cable is delivered into the anchor cable conduit 33. The anchor cable moves upward and enters between the first roller 3112 and the second roller 3123 of the anchor cable pushing assembly 31. The anchor cable construction control unit controls the first rotary driver 3111 to drive the first roller 3112 to rotate and the second rotary driver 3122 to drive the second roller 3123 to rotate. The first roller 3112 and the second roller 3123 are driven to rotate in opposite directions to drive the anchor cable held by the two to be conveyed upward.

[0156] S13: The anchor cable, conveyed upward by the first roller 3112 and the second roller 3123, enters the anchor cable shearing assembly 32. The anchor cable enters the channel 3211 of the shearing housing 321 through the shearing guide 3212 at the bottom of the shearing housing 321 and is then conveyed into the borehole from the top of the shearing housing 321. When the anchor cable is conveyed to the set length, the anchor cable construction control unit controls the first roller 3112 and the second roller 3123 to stop rotating, and the anchor cable construction control unit controls the telescopic shear movable part 325 to drive the telescopic shear 323 to move left and right. The left and right movement of the telescopic shear 323 and the closing of the fixed shear 322 cooperate to cut the anchor cable.

[0157] S14: The cut end of the anchor cable is detachably fixed to the output end of the hydraulic motor 41 through the anchor cable joint 42. The anchor cable construction control unit controls the mixing hydraulic motor 41 to drive the anchor cable to be mixed in the borehole through the anchor cable joint 42. After the mixing is completed, the cut end of the anchor cable and the anchor cable joint 42 are separated.
