Description

Technical Field

[0001] This invention relates to the field of coal mining tools, and in particular to an underground sandbox relocation device. Background Technology

[0002] Underground fire sandboxes are specialized sand storage containers that are permanently installed in flammable / electrical / oil areas underground. They are equipped with fire shovels, buckets, and sandbags and are mainly used to cover and smother fires (especially oil and electrical fires, to avoid the risk of electric shock or boiling over when using water to extinguish them). They are essential facilities for the initial fire fighting in mines.

[0003] Volumetric grading: Commonly categorized as 0.2m³ (power distribution point, conveyor head), 0.4m³ (wellhead, material storage, explosives storage), and 0.5m³ (large chamber); common dimensions are 1000×600×500mm and 1000×700×800mm; sand volume must reach 4 / 5 of the volume or above the mark, and compaction and dampness are strictly prohibited.

[0004] Material: Thickened steel plate (explosion-proof and impact-proof) should be used first, and the container should be welded and sealed. The bottom should be sloped at 30°~45° to facilitate rapid sand discharge. The entire container should be painted bright red and marked "Firefighting Sand Box" and instructions for use. The top can be equipped with a rainproof / dustproof cover to prevent the sand from getting damp.

[0005] Supporting equipment: Each box must be equipped with 2 fire shovels, 2 fire buckets, and an appropriate amount of sandbags (usually filling 2 / 3 of the sandbox area); placed together with fire extinguishers (dry powder / CO2), ≤5m away from the risk point, and fixed securely without obstructing passage.

[0006] When tunneling is carried out in an underground coal mine, all kinds of equipment need to be moved forward in the direction of tunneling to ensure the normal progress and safety of construction. The same applies to underground fire sandboxes. The conventional operation is to empty the sand in the sandbox and transport the sandbox, and then backfill the sand in batches later, which is very troublesome. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an underground sandbox relocation device, which solves the technical problem that moving fire-fighting sandboxes underground is very troublesome.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0011] This invention provides a downhole sandbox relocation device, comprising a relocation frame that moves along the downhole surface, a sliding bracket that is horizontally slidably connected to the relocation frame and slides into the bottom of the downhole sandbox as it moves, and a lifting assembly disposed on the relocation frame and vertically raising and lowering the sliding bracket. The relocation frame includes two sets of horizontally spaced parallel relocation brackets, traveling pulleys disposed on the lower side of the relocation brackets near both ends, a connecting frame horizontally connected to one end of the two relocation brackets, and a relocation handle disposed on the upper side of the connecting frame. A relocation station for inserting the downhole sandbox is formed between the two relocation brackets and the connecting frame. The sliding brackets are provided in two sets and are horizontally slidably connected to the relocation brackets along the direction perpendicular to the length of the relocation brackets.

[0012] This invention provides an underground sandbox relocation device. When relocating an underground fire-fighting sandbox using this device, the relocation frame is moved to one side of the sandbox. Then, the openings at the ends of the two relocation frames furthest from the connecting frame are aligned with the sandbox. The relocation frame is moved further until the sandbox is fully in the relocation position. The two sets of sliding brackets are moved horizontally to the lower end of the sandbox. Then, the sliding brackets are lifted upwards by the lifting assembly, thereby lifting the sandbox off the ground. At this point, the entire relocation device and the underground fire-fighting sandbox can be moved to the designated position via the traveling pulleys. The sandbox is then placed on the ground by the lifting assembly, and the relocation brackets are then slid out to complete the relocation of the sandbox. This solution makes the relocation of the sandbox more convenient and faster.

[0013] Optionally, the relocation bracket includes vertical frames located at both ends and arranged vertically, and a horizontal frame connected to the top of the two vertical frames. The lifting assembly includes two sets of lifting cylinders vertically downward connected to the lower side of the horizontal frame near the two ends, and a lifting bracket horizontally connected to the piston rod ends of the two sets of lifting cylinders. The two ends of the lifting bracket are inserted and vertically slidably connected to the two sides of the two vertical frames that are close to each other.

[0014] The two horizontal frames are driven to move vertically by two sets of displacement brackets and a total of four sets of lifting cylinders, which makes the force distribution during the lifting process more uniform. At the same time, when the horizontal frame drives the sliding bracket to lift the sand box, the horizontal frame will receive a certain torsional force. This solution distributes the torsional force by inserting and sliding the end of the horizontal frame to the vertical frames on both sides, thereby improving the lifting effect.

[0015] Optionally, the sliding bracket includes multiple horizontally arranged sliding plates at uniform intervals and a positioning plate vertically connected to one end of the multiple sliding plates. The sliding plates are horizontally slidable and connected to the lifting bracket perpendicular to the length direction of the lifting bracket. The positioning plate slides with the sliding plates and abuts against the side end of the lifting bracket. The sliding plates on the two sets of sliding brackets are arranged intermittently.

[0016] By setting the sliding bracket as a positioning plate and multiple sliding plates, the sliding plates of the two sets of sliding brackets are arranged intermittently, that is, each sliding plate can abut against a larger area of ​​the lower end surface of the sand box, and cooperate with each other to provide a more stable lifting and repositioning effect.

[0017] Optionally, the lower end of the lifting bracket is provided with a guide groove along its vertical length for the sliding plate to slide and insert. The two sets of lifting brackets are provided with "T"-shaped insertion holes connected to the guide groove at their opposite ends. The upper surface of the sliding plate is provided with a "T"-shaped insertion block connected to one end of the positioning plate and inserted into the "T"-shaped insertion hole at the part near the positioning plate. The end of the sliding plate away from the positioning plate is flat.

[0018] By creating a guide groove at the lower end of the lifting bracket, the sliding plate slides horizontally along the guide groove. At the same time, one end of the sliding plate is made flat, so that when the lifting bracket abuts against the ground, the sliding plate can slide close to the ground and insert into the lower end of the sandbox. This makes it more convenient to insert the sliding plate into the bottom of the sandbox even if the bottom surface of the sandbox is in direct contact with the ground. In addition, a "T"-shaped insert is set between the sliding plate and the positioning plate, so that the "T"-shaped insert is inserted into the "T"-shaped insertion hole as the sliding plate is inserted, thereby improving the support effect of the sliding plate under pressure.

[0019] Optionally, the relocation frame further includes a blocking bracket rotatably connected to the end of the relocation bracket away from the connecting frame. The pivot of the blocking bracket is vertical. A universal pulley is provided on the lower side of the blocking bracket away from the relocation bracket. When the two sets of blocking brackets rotate perpendicular to the relocation bracket, they connect to each other and close the relocation station.

[0020] By rotating the connecting and locking bracket at the end of the relocation bracket away from the connecting frame, the two sets of locking brackets can be fixed at the ends that are close to each other when rotated to be perpendicular to the relocation bracket, thereby sealing the relocation station. This ensures that the sandbox will not fall out of the relocation station when encountering a slope during the movement, making it safer. At the same time, the installation of universal pulleys on the locking bracket can improve the support and movement effect of the entire relocation device.

[0021] Optionally, the two sets of the blocking brackets are fixedly connected by a locking frame. The top of the blocking bracket is provided with a plurality of vertically oriented positioning holes evenly spaced along the horizontal direction. The locking frame includes a horizontally arranged locking link and a locking insert that is evenly spaced along the length of the locking link and vertically inserted into the positioning holes on the two sets of the blocking brackets.

[0022] When the sandbox is lifted off the ground in the relocation station, rotate the two sets of blocking brackets and align the locking pins on the locking linkage with the positioning holes on the top of the two sets of blocking brackets, then insert them to completely fix the two sets of blocking brackets, which is very convenient and secure.

[0023] Optionally, the connecting frame is horizontally slidably connected to two sets of support frames supported at the lower end of the sliding bracket, with the traveling pulleys evenly spaced at the lower end of the support frame, and one end of the support frame moves to one side of the blocking bracket and is fixed to the blocking bracket.

[0024] By horizontally sliding the support frame on the connecting frame, the two sets of support frames can slide perpendicular to the length of the connecting frame and move to be fixed with the blocking bracket. At this time, the support frame is supported on the lower end of the interlocking sliding plates, thereby providing a certain support. This ensures that when the entire relocation device moves with the sandbox, the sandbox can be adequately supported, making it safer.

[0025] Optionally, the lower end of the connecting frame has two horizontally formed "T"-shaped grooves along its own length direction, and the upper end of the support frame has a "T"-shaped slide rail that slides into the "T"-shaped grooves along its own length direction. The end of the support frame near the blocking bracket abuts against the blocking bracket and has a locking hole in the vertical direction for the locking rod to be vertically inserted.

[0026] By opening a "T"-shaped groove at the lower end of the connecting frame, the "T"-shaped slide rail on the support frame slides and inserts into the "T"-shaped groove, thereby ensuring that the support frame can be more secure when bearing the pressure of the sand box. At the same time, the other end directly abuts against the sealing bracket and is locked by the locking rod, thereby fixing the support frame.

[0027] Optionally, the relocation frame further includes a miscellaneous storage rack horizontally disposed on top of the two sets of relocation supports.

[0028] By horizontally setting up a storage rack on top of the two sets of relocation supports, various tools such as fire shovels, fire buckets, appropriate amounts of sandbags, and fire extinguishers can be placed on the storage rack for simultaneous movement and transportation when the sandbox is moved, making it more convenient.

[0029] Optionally, the repositioning handle includes a gripping handle and a dragging handle. The gripping handle includes multiple first vertical rods vertically welded to the connecting frame and a first horizontal rod horizontally welded to the top of the multiple first vertical rods. The dragging handle includes a second vertical rod rotatably connected to the top of the connecting frame via a pivot and a second horizontal rod horizontally welded to the top of the second vertical rod. The second horizontal rod is snapped and fixed to the first horizontal rod by a buckle.

[0030] By setting up a grip handle and a drag handle, the sandbox relocation device can be operated by holding the grip handle when pushing it, and when it is necessary to move the sandbox uphill, the sandbox relocation device can be dragged in the opposite direction by holding the drag handle, making the movement process more convenient.

[0031] (III) Beneficial Effects

[0032] The beneficial effects of this invention are as follows: When using the underground sandbox relocation device of this invention to relocate an underground fire-fighting sandbox, the relocation vehicle is moved to one side of the sandbox, and then the openings at the ends away from the connecting frame between the two relocation units are aligned with the sandbox. The relocation vehicle is then moved further so that the sandbox is fully inserted into the relocation position. The two sets of sliding brackets are moved horizontally to the lower end of the sandbox, and then the sliding brackets are moved upward by the lifting component, thereby lifting the sandbox off the ground. At this time, the entire relocation device and the underground fire-fighting sandbox can be moved to the designated position by the traveling pulleys. Then, the sandbox is placed on the ground by the lifting component, and then the relocation brackets are slid out to complete the relocation of the sandbox. This solution makes the relocation of the sandbox more convenient and faster. Attached Figure Description

[0038] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] The underground sandbox relocation device proposed in this invention allows for the relocation of underground fire-fighting sandboxes. The relocation frame is moved to one side of the sandbox, aligning the openings at the ends of the two relocation frames furthest from the connecting frame with the sandbox. The relocation frame is then moved further until the sandbox is fully in the relocation position. Two sets of sliding supports are moved horizontally to the bottom of the sandbox, and then the lifting assembly moves the sliding supports upwards, lifting the sandbox off the ground. The entire relocation device and the underground fire-fighting sandbox can then be moved to a designated position using the traveling pulleys. The sandbox is then placed on the ground using the lifting assembly, and the relocation supports are slid out to complete the sandbox relocation. This solution makes sandbox relocation more convenient and faster.

[0040] 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.

[0041] Reference Figures 1-3 A sandbox relocation device for underground wells includes a relocation frame 1 that moves along the underground ground, a sliding support 2 that is horizontally slidably connected to the relocation frame 1 and slides into the bottom of the underground sandbox as it moves, and a lifting assembly 3 that is mounted on the relocation frame 1 and raises and lowers the sliding support 2 in the vertical direction.

[0042] The relocation frame 1 includes two sets of relocation brackets 11 arranged horizontally at intervals, a travel pulley 12 located on the lower side of the relocation brackets 11 near both ends, a connecting frame 13 horizontally connected to one end of the two relocation brackets 11, a relocation handle 14 located on the upper side of the connecting frame 13, and a miscellaneous item placement rack 15 horizontally located on the top of the two sets of relocation brackets 11.

[0043] Two relocation brackets 11 and a connecting frame 13 form a relocation station 16 for inserting an underground sandbox. Two sets of sliding brackets 2 are provided and are horizontally connected to the relocation brackets 11 along the length of the vertical relocation brackets 11. When using this underground sandbox relocation device to relocate an underground fire sandbox, move the relocation vehicle 1 to one side of the sandbox, then align the openings of the two sets of relocation brackets away from the connecting frame 13 with the sandbox. Continue moving the relocation vehicle 1 so that the sandbox is fully inserted into the relocation station 16. Move the two sets of sliding brackets 2 horizontally to the lower end of the sandbox, and then use the lifting component 3 to move the sliding brackets 2 upward, thereby lifting the sandbox off the ground. At this time, the entire relocation device and the underground fire sandbox can be moved to the designated position by the traveling pulley 12. Then, the sandbox is placed on the ground by the lifting component 3, and then the relocation brackets 11 are slid out to complete the relocation of the sandbox.

[0044] When moving the sandbox, its various tools, such as fire shovels, fire buckets, appropriate amounts of sandbags, fire extinguishers, etc., can be placed on the miscellaneous storage rack 15 for simultaneous movement and transportation, making it more convenient.

[0045] The relocation bracket 11 includes vertical frames 111 located at both ends and arranged vertically, and horizontal frames 112 horizontally welded to the top of the two vertical frames 111. The traveling pulleys 12 on the relocation bracket 11 are rotatably connected to the bottom of the two vertical frames 111 through bearings. The lifting assembly 3 includes two sets of lifting cylinders 31 that are vertically connected and fixed to the lower side of the horizontal frame 112 near the two ends by bolts, and lifting brackets 32 that are horizontally fixed to the piston rod ends of the two sets of lifting cylinders 31 by bolts. The two vertical frames 111 in the same group have a long sliding groove 1111 vertically opened on one side that is close to each other. The two ends of the lifting bracket 32 ​​are vertically inserted into the long sliding groove 1111 and slide in the vertical direction. The two horizontal frames 112 are driven to move vertically by two sets of displacement brackets 11 and a total of four sets of lifting cylinders 31, so that the force is more evenly distributed during the lifting process. At the same time, when the horizontal frame 112 drives the sliding bracket 2 to lift the sand box, the horizontal frame 112 will receive a certain torsional force. The torsional force is dispersed by inserting and sliding the end of the horizontal frame 112 to the vertical frames 111 on both sides.

[0046] The sliding bracket 2 includes multiple horizontally arranged sliding plates 21 at even intervals and a positioning plate 22 vertically welded to one end of the sliding plates 21. The sliding plates 21 are horizontally slidable and connected to the lifting bracket 32 ​​perpendicular to its length direction. The positioning plate 22 slides along with the sliding plates 21 and abuts against the side end of the lifting bracket 32. Multiple magnetic pieces are embedded in the positioning plate 22, so that the positioning plate 22 can be magnetically fixed when it abuts against the side end of the lifting bracket 32. The lower end of the lifting bracket 32 ​​is provided with a guide groove 321 for sliding and inserting the sliding plate 21 along the direction perpendicular to its own length. The two sets of lifting brackets 32 are provided with "T"-shaped insertion holes 322 connected to the guide groove 321 at the opposite ends. The upper end of the sliding plate 21 is welded with a "T"-shaped insertion block 23 connected to one end of the positioning plate 22 and inserted into the "T"-shaped insertion hole 322. The end of the sliding plate 21 away from the positioning plate 22 is flat. One end of the sliding plate 21 is made flat, so that when the lifting bracket 32 ​​abuts against the ground, the sliding plate 21 can slide close to the ground and be inserted into the lower end of the sand box. This makes it easier to insert the sliding plate 21 into the bottom of the sand box even if the bottom surface of the sand box is in direct contact with the ground. At the same time, a "T"-shaped insert 23 is set between the sliding plate 21 and the positioning plate 22, so that the "T"-shaped insert 23 is inserted into the "T"-shaped insertion hole 322 as the sliding plate 21 is inserted, thereby improving the support effect of the sliding plate 21 when it is under pressure.

[0047] The sliding plates 21 on the two sets of sliding brackets 2 are arranged intermittently. The sliding plates 21 of the two sets of sliding brackets 2 are arranged intermittently with each other, that is, each sliding plate 21 can abut against a larger area of ​​the lower end surface of the sand box, and cooperate with each other to provide a more stable lifting and repositioning effect.

[0048] The relocation frame 1 also includes a blocking bracket 17 rotatably connected to the end of the relocation bracket 11 away from the connecting frame 13 via a rotating shaft. The rotating shaft of the blocking bracket 17 is vertical. A universal pulley 171 is bolted to the lower end of the blocking bracket 17 away from the relocation bracket 11. When the two sets of blocking brackets 17 rotate to be perpendicular to the relocation bracket 11, they connect to each other and close the relocation station 16. When the two sets of blocking brackets 17 rotate to be perpendicular to the relocation bracket 11, they are fixed at the ends that are close to each other, thereby closing the relocation station 16. This ensures that the sandbox will not fall out of the relocation station 16 when encountering a slope during the movement, making it safer. At the same time, the universal pulley 171 on the blocking bracket 17 can improve the support and movement effect of the entire relocation device.

[0049] Two sets of blocking brackets 17 are fixedly connected by locking frames 172. The top of each blocking bracket 17 has multiple vertically oriented positioning holes 173 evenly spaced horizontally. The locking frame 172 includes a horizontally positioned locking link 1721 and locking inserts 1722 that are welded evenly at intervals along the length of the locking link 1721 and vertically inserted into the positioning holes 173 on both sets of blocking brackets 17. When the sandbox is lifted off the ground within the relocation station 16, the two sets of blocking brackets 17 are rotated, aligning the locking inserts 1722 on the locking link 1721 with the positioning holes 173 on the top of the two sets of blocking brackets 17, and then inserted, thereby completely fixing the two sets of blocking brackets 17.

[0050] The connecting frame 13 is horizontally slidably connected to two sets of support frames 4 supported at the lower end of the sliding bracket 2. The lower end of each support frame 4 is equipped with evenly spaced traveling pulleys 12 via bearings. One end of each support frame 4 slides to the side of the blocking bracket 17 and is fixed thereto. The support frames 4 are supported at the lower end of the interlocking sliding plates 21, providing sufficient support so that the sandbox can be adequately supported and safer when the entire relocation device moves with the sandbox.

[0051] The lower end of the connecting frame 13 has two horizontally formed "T"-shaped grooves 131 along its length. The upper end of the support frame 4 has an integrally formed "T"-shaped slide rail 41 that slides into the "T"-shaped grooves 131. One end of the support frame 4 near the sealing bracket 17 abuts against the sealing bracket 17 and has a locking hole 42 in the vertical direction for the vertical insertion of the locking rod 1722. The "T"-shaped slide rail 41 on the support frame 4 slides into the "T"-shaped grooves 131, thus ensuring that the support frame 4 is more secure when bearing the pressure of the sandbox. At the same time, the other end directly abuts against the sealing bracket 17 and is locked by the locking rod 1722, thereby fixing the support frame 4.

[0052] The relocation handle 14 includes a grip handle 141 and a drag handle 142. The grip handle 141 includes multiple first vertical rods 1411 vertically welded to the connecting frame 13 and a first horizontal rod 1412 horizontally welded to the top of the multiple first vertical rods 1411. The drag handle 142 includes a second vertical rod 1421 rotatably connected to the top of the connecting frame 13 via a pivot and a second horizontal rod 2422 horizontally welded to the top of the second vertical rod 1421. The second horizontal rod 2422 is snapped and fixed to the first horizontal rod 1412 by a buckle. This allows the sandbox relocation device to be operated by holding the grip handle 141 when pushing it, and to be dragged in the opposite direction by holding the drag handle 142 when moving the sandbox uphill, making the movement process more convenient.
