TECHNICAL FIELD

[0001] The present application belongs to the technical field of mine rescue tools, and particularly relates to a track escape crowbar and emergency rescue anchor rod dual-purpose tool. BACKGROUND

[0002] With the development of the mining industry, the increasing busy of mine car track transportation and the continuous improvement of mine car track transportation safety requirements, the track transportation system is facing more challenges and demands. Track escape and emergency rescue work is an important part of ensuring operation safety and rapid response. In the event of track failure, vehicle derailment, natural disasters or accidents, it is crucial to quickly and effectively perform escape and rescue operations. In the track escape process, common tools such as crowbars and anchor rods have their specific functions, but they need to be used in different working scenarios.

[0015] Compared with the prior art, the track escape crowbar and emergency rescue anchor dual-purpose tool provided by the application has at least the following beneficial effects:

[0016] (1) The upper and lower plug-in mounting mechanisms of the mounting seat are connected with the crowbar mechanism and the anchor mechanism respectively, realizing one tool with two functions, that is, the crowbar mechanism can complete the crowbar operation and escape operation of the track component, and the anchor mechanism can complete the emergency anchoring and supporting operation, so that multiple sets of tools do not need to be carried, the equipment load of the rescue personnel is significantly reduced, and the operation demand in a limited space or in an emergency situation is met.

[0018] (3) The baffle is correspondingly arranged with the grouting hole, when grouting, the high-pressure slurry enters the anchoring pipe through the connecting pipe, the threaded pipe and the transition pipe, and then exerts an outward pushing force on the baffle, so that the baffle overcomes its own gravity or the initial limiting state and opens outward, ensuring that the slurry can uniformly flow out to the gap between the anchoring pipe and the surrounding rock through the multiple grouting holes. The automatic opening design during grouting avoids the blockage of the grouting hole, ensures that the slurry can fully fill the gap of the surrounding rock, and forms a complete and dense slurry wrapping layer. At the same time, the sharp structure of the anti-skid barb after grouting forms mechanical engagement with the surrounding rock slurry, greatly increases the friction and pullout resistance between the anchor mechanism and the surrounding medium, effectively prevents the anchor from loosening or falling off when subjected to stress, such as supporting the rescue load and resisting the deformation of the surrounding rock, and significantly improves the reliability of the emergency anchoring.

DETAILED DESCRIPTION

[0027] The present application will be further described below in conjunction with examples.

[0028] Please refer to Figures 1-4 The present application provides a track escape crowbar and emergency rescue anchor rod dual-purpose tool, which comprises a mounting seat 1, the mounting seat 1 is provided with a plug-in mounting mechanism 2 at the top and the bottom, the plug-in mounting mechanism 2 at the top position is internally provided with a crowbar mechanism 3, and the plug-in mounting mechanism 2 at the bottom position is internally provided with an anchor rod mechanism 4.

[0029] Further as Figure 3 ​As shown, it is worth noting that the plug-in mounting mechanism 2 includes a fixed sleeve 201 fixedly connected to the outer end of the mounting base 1, a plurality of limiting sliding rails 202 are fixedly connected to the inner wall of the fixed sleeve 201, the outer wall of the plurality of limiting sliding rails 202 is slidingly connected to a limiting sliding groove 203, the inner end of the limiting sliding groove 203 is fixedly connected to a plug-in stud head 204, the outer end of the limiting sliding groove 203 is fixedly connected to a guide column 205, the outer end of the fixed sleeve 201 is fixedly connected to a cover disc 206, the inside of the cover disc 206 is rotatably connected to a rotating disc 207, a plurality of arc-shaped guide grooves 208 are formed on the surface of the rotating disc 207, the outer wall of the rotating disc 207 is fixedly connected to a worm gear sleeve 209, a concave frame 210 is fixedly connected to the top of the cover disc 206 near the front end, a worm 211 is rotatably connected to the inner wall of the concave frame 210, a knob 212 is fixedly connected to one side of the worm 211 penetrating through the concave frame 210. By setting the plug-in mounting mechanism 2, the rotating disc structure driven by the worm gear is adopted, the worm 211, the worm gear sleeve 209 are driven to rotate by rotating the knob 212, the arc-shaped guide groove 208 of the rotating disc 207 pushes the guide column 205, and then drives the plug-in stud head 204 to expand and contract along the limiting sliding rail 202, realizing the quick connection and disassembly of the crowbar mechanism 3 and the anchor rod mechanism 4 with the mounting base 1. The worm gear transmission has self-locking property, which ensures that the connection is not easy to loosen after connection, ensures the safety of operation, the whole switching process does not need additional tools, the operation is simple, can quickly complete the function conversion in emergency, reduces the rescue preparation time, and improves the rescue efficiency.

[0030] Further as shown in Figure 3 It is worth noting that the end of each plug-in stud head 204 is designed in a hemispherical shape. Compared with a sharp or flat design, the hemispherical end can reduce the contact area and frictional resistance with the inner wall of the plug-in hole of the first crowbar 301 and the connecting pipe 401. During the expansion and contraction process of the plug-in stud head 204, the hemispherical surface can automatically align the plug-in hole through the arc guidance, avoiding jamming or being stuck, especially in the fast operation scene of emergency rescue, which can reduce the time waste caused by alignment deviation; the plurality of guide columns 205 are respectively slidingly connected to the inner wall of the corresponding arc-shaped guide groove 208, and the plurality of guide columns 205 are respectively embedded in the corresponding arc-shaped guide groove 208. When the rotating disc 207 rotates through the worm gear structure, the curve trajectory of the arc-shaped guide groove 208 will synchronously push all the guide columns 205 to move axially along the limiting sliding rail 202, and then drive the plug-in stud head 204 to uniformly expand and contract. This synchronization ensures that the plurality of plug-in stud heads 204 are simultaneously inserted into or separated from the plug-in holes of the crowbar and the anchor rod, avoiding the connection loosening caused by uneven force on a single stud head, and improving the firmness of the overall connection.

[0031] Further as shown in Figure 3As shown, it is worth noting that the inner part of the rotating disc 207 is provided with a circular opening, which provides a through space for the first crowbar 301 of the crowbar mechanism 3 and the connecting pipe 401 of the anchor rod mechanism 4, ensuring that the main components of the two mechanisms can smoothly pass through the rotating disc 207 when connected with the mounting seat 1, and the existence of the rotating disc 207 will not hinder the assembly or operation of the tool; the worm 211 is engaged with the worm gear sleeve 209, and the worm gear transmission has a reverse self-locking feature, that is, the worm gear cannot drive the worm 211 to rotate, and when the plug-in stud 204 is connected with the plug-in hole of the crowbar mechanism 3 or the anchor rod mechanism 4, even if it is subjected to external load such as reaction force when prying or tension when anchoring, the worm gear sleeve 209 will not rotate in the opposite direction, ensuring that the plug-in stud 204 will not automatically retract and loosen, and structurally ensuring the stability and safety of the operation process.

[0032] Further as shown in Figure 4 , it is worth noting that the crowbar mechanism 3 includes a first crowbar 301 detachably connected to the inner wall of the fixed sleeve 201, a second crowbar 302 slidingly connected to the top of the first crowbar 301, and a positioning pin 303 rotatably connected to the two sides of the first crowbar 301 corresponding to the second crowbar 302, a top head 304 threadedly connected to the end of the second crowbar 302, and a pry plate 305 fixedly connected to the outer end of the top head 304. By providing the crowbar mechanism 3, the first crowbar 301 is detachably connected with the fixed sleeve 201 through the plug-in mounting mechanism 2, and when it is necessary to switch to the anchor rod mechanism 4 for operation, the crowbar mechanism 3 can be quickly detached to avoid tool redundancy; without carrying multiple sets of different lengths or types of crowbars, the rescue equipment is further simplified, and the carrying convenience is improved.

[0033] Further as shown in Figure 4 , it is worth noting that the outer wall of the first crowbar 301 is provided with a plurality of plug-in holes corresponding to the plug-in stud 204, and the two sides of the first crowbar 301 and the two sides of the second crowbar 302 are provided with a plurality of positioning holes corresponding to the positioning pin 303. The first crowbar 301 is slidingly connected with the second crowbar 302, and the overall length can be adjusted according to the rescue requirements such as prying distance and force application space size. When operating in a narrow space, the length is shortened for flexible operation; when it is necessary to increase the force arm to pry heavy objects, the length is lengthened to reduce the force intensity through the lever principle.

[0034] According to the above working process, the plug-in mounting mechanism 2 on the mounting seat 1 connects the crowbar mechanism 3 and the anchor rod mechanism 4 respectively, realizes one tool for two purposes, can complete track component prying and escape operation through the crowbar mechanism 3, and can perform emergency anchoring and supporting operation through the anchor rod mechanism 4, without the need to carry multiple tools, significantly reducing the equipment load of rescue personnel, and being suitable for operation requirements in limited space or emergency situations.

[0035] Further as shown in Figure 5 ,Figure 6 and Figure 7 As shown, it is worth noting that the anchor rod mechanism 4 comprises a connecting pipe 401 detachably connected to the inner wall of the fixing sleeve 201, the bottom of the connecting pipe 401 is fixedly connected with a threaded pipe 402, the outer wall of the threaded pipe 402 is fixedly connected with a grout stopper 403, the outer wall of the threaded pipe 402 is sleeved with a splash plate 404, the outer wall of the threaded pipe 402 is rotatably connected with a locking nut 405 corresponding to the splash plate 404, the bottom of the threaded pipe 402 is fixedly connected with a transition pipe 406, the bottom of the transition pipe 406 is fixedly connected with an anchoring pipe 407, a plurality of grouting holes 408 are arranged on the outer wall of the anchoring pipe 407, the outer wall of the anchoring pipe 407 is rotatably connected with a plurality of baffles 409 corresponding to the grouting holes 408, the outer wall of each of the plurality of baffles 409 is fixedly connected with an anti-skid barb 410, the bottom of the anchoring pipe 407 is fixedly connected with a bottom sleeve 411, and the bottom of the bottom sleeve 411 is fixedly connected with a drill bit 412. Through the setting of the anchor rod mechanism 4, the connecting pipe 401 is detachably connected with the plug-in mounting mechanism 2 of the mounting seat 1, and the emergency anchoring operation can be independently completed. When the track area collapses, the surrounding rock loosens, or temporary support rescue space is needed, the anchoring pipe 407 can be drilled into the rock layer or soil through the drill bit 412, and then grout is injected through the grouting holes 408. The solidified grout and the surrounding rock form a firm anchoring, providing a stable support point for rescue operations, and cooperating with the "fixing-support" scene that cannot be covered by the crowbar mechanism 2. For example, preventing secondary collapse during rescue, fixing rescue equipment, and extending the function of the tool from single "prying to escape" to "anchoring guarantee" field to adapt to more complex emergency rescue needs.

[0036] Further as shown in Figure 5 , Figure 6 and Figure 7 It is worth noting that a plurality of plug-in holes corresponding to the plug-in column head 204 are arranged on the outer wall of the connecting pipe 401, the plug-in holes correspond to the plug-in column head 204, and through the driving of the plug-in mounting mechanism 2, the plug-in column head 204 can be accurately embedded in the plug-in hole, and the connection between the anchor rod mechanism 4 and the mounting seat 1 can be quickly completed. This structure does not require additional fastening tools, and the plurality of plug-in holes are uniformly distributed; the connecting pipe 401, the threaded pipe 402, the transition pipe 406 and the anchoring pipe 407 are connected through the inside, forming a complete grouting channel. The grout can flow smoothly from the inlet of the connecting pipe 401 through each component, and finally flow out through the grouting holes 408 of the anchoring pipe 407, ensuring that the grout can uniformly fill the gap between the anchoring pipe 407 and the surrounding rock, avoiding the problem of insufficient anchoring caused by channel blockage, and enhancing the anchoring strength.

[0037] Further as shown in Figure 5 , Figure 6 and Figure 7As shown, it is worth noting that the inside of the grouting hole 408 is provided with a stop block corresponding to the baffle plate 409. The stop block can block the baffle plate 409 from turning outwards excessively during grouting by contacting the inside of the baffle plate 409. When the high-pressure slurry pushes the baffle plate 409 to open, the stop block can limit the maximum opening angle of the baffle plate 409 to 30°-60°, so as to ensure that the baffle plate 409 will not affect the slurry outflow efficiency due to too small turning angle, and will not cause deformation of the baffle plate 409 or damage to the connection structure of the anchoring pipe 407 due to too large turning angle. The limiting effect makes the baffle plate 409 maintain a stable open state during the grouting process, ensures that the slurry outflow amount of the plurality of grouting holes 408 is uniform, and avoids the problem of insufficient local grouting amount caused by excessive turning of a single baffle plate 409.

[0038] The present scheme has the following working process: in actual use, the first crowbar 301 is connected with the fixed sleeve 201 through the plug-in installation mechanism 2, the knob 212 is rotated to drive the worm 211 and the worm gear sleeve 209 to rotate, the arc-shaped guide groove 208 of the rotating disc 207 pushes the guide column 205, the plug-in column head 204 is driven to extend along the limiting sliding rail 202 and is embedded into the plug-in hole in the outer wall of the first crowbar 301, and the fixing is completed. The second crowbar 302 is slid to the required length, the positioning pin 303 is inserted and locked, the top head 304 and the crowbar plate 305 suitable for the operation requirement are selected, the adjusted crowbar mechanism 3 is used, the crowbar plate 305 contacts the objects to be pried such as track components and derailed vehicles, force is applied by means of the lever principle to pry, and the operation of getting out of trouble is realized. The knob 212 is reversely driven to drive the worm 211, the worm gear sleeve 209 drives the rotating disc 207 to reversely rotate, the arc-shaped guide groove 208 pulls the guide column 205, the plug-in column head 204 is retracted into the limiting sliding rail 202, and the current mechanism crowbar can be disassembled. After another mechanism is replaced, the fixing is completed by repeatedly rotating the knob 212 in the forward direction, the quick switching is realized, and no additional tool is needed. After the crowbar mechanism 3 is disassembled, the connecting pipe 401 is connected with the fixed sleeve 201 through the plug-in installation mechanism 2, the plug-in principle is the same as described above, the anchoring pipe 407 is drilled into the surrounding rock or soil through the bottom drill bit 412 to form preliminary positioning, the grouting equipment is connected with the connecting pipe 401, the slurry sequentially passes through the threaded pipe 402, the transition pipe 406 and enters the anchoring pipe 407, the high-pressure slurry pushes the baffle plate 409 to open the stop block in the grouting hole 408 to limit the opening angle thereof, the slurry flows into the gap between the anchoring pipe 407 and the surrounding rock through the grouting hole 408, the grout stopper 403 prevents the slurry from leaking, the splash-proof plate 404 blocks the splashes, after the grouting is completed, the slurry pressure disappears, the baffle plate 409 is reset under the guidance of the self-gravity and the stop block, and the anti-skid barbs 410 on the outer wall are embedded into the solidified slurry or surrounding rock to form firm anchoring.

[0039] In summary: through the upper and lower plug-in mounting mechanism 2 of the mounting seat 1, the pry bar mechanism 3 and the anchor rod 4 mechanism are connected respectively, realizing dual-purpose of one tool, which can complete track component prying and escape operation through pry bar mechanism 3, and can complete emergency anchoring and supporting operation through anchor rod mechanism 4, without carrying multiple sets of tools, significantly reducing the equipment load of rescue personnel, suitable for operation requirements in limited space or emergency situations; by setting the plug-in mounting mechanism 2, adopting the worm gear driven rotary table structure, rotating the knob 212 to drive the worm 211 and the worm gear sleeve 209, the arc-shaped guide groove 208 of the rotary table 207 pushes the guide column 205, and then drives the plug-in column head 204 to extend and retract along the limiting slide rail 202, realizing quick connection and disassembly of the pry bar mechanism 3 and the anchor rod mechanism 4 with the mounting seat 1, the worm gear transmission has self-locking property, ensuring that it is not easy to loosen after connection, ensuring operation safety, the whole switching process does not need additional tools, the operation is simple, the function conversion can be quickly completed in emergency situations, reducing rescue preparation time and improving rescue efficiency; by setting the anchor rod mechanism 4, the connecting pipe 401 and the plug-in mounting mechanism 2 of the mounting seat 1 are detachably connected, which can independently complete emergency anchoring operation, when the track area collapses, the surrounding rock loosens or temporary support rescue space is needed, the drill bit 412 can be used to drill the anchoring pipe 407 into the rock layer or soil, and then the grouting hole 408 is used to inject grout, the hardened grout and surrounding rock form a firm anchor, providing a stable support point for rescue operation, cooperating with the "fixed-support" scene that the pry bar mechanism 2 cannot cover.
