Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically an automatic explosion-proof installation and disassembly lifting device. Background Technology

[0002] Automatic explosion-proof devices for coal mines are core safety equipment for addressing the risk of gas or coal dust explosions in underground coal mines. They quickly sense the explosion shock wave and automatically trigger the spraying of explosion-suppressing media to prevent the spread of flames. Automatic explosion-proof devices must be fixedly installed on the top of the coal mine roadway, and the shock wave receiver of the automatic explosion-proof device must be facing the direction of the potential explosion source.

[0003] Because automatic explosion-proof devices in coal mines are installed and fixed at the top of the coal mine roadway, their installation requires hoisting them to the top of the roadway. Typically, lifting lugs are fixed at the top of the roadway to hang a chain, which is then used to hoist the automatic explosion-proof device for lifting and lowering. Meanwhile, workers use scaffolding at the top of the roadway to install and dismantle the device.

[0004] The existing method of installing and dismantling automatic explosion-proof devices in coal mines using chain hoists requires the cooperation of multiple workers and two chain hoists to lift the devices from both ends, making the operation complex and posing a risk of the devices falling.

[0005] Therefore, an automatic explosion-proof installation, dismantling, and lifting device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] Preferably, a bracket is fixedly connected to the side of the vertical arm away from the explosion-proof device; a sleeve is fixedly connected to the top of the bracket; and the clamping screw slides through the sleeve.

[0009] Preferably, a guide rail is fixedly connected to the center of the top surface of the support platform; multiple slide blocks are slidably installed on the guide rail; a mounting plate is bolted to the top surface of the slide blocks; and a support plate that contacts the bottom of the explosion-proof device is hinged to the top surface of the mounting plate.

[0013] Preferably, clamping blocks are slidably mounted on both sides of the inner cavity of the slide block; fixing screws are threadedly mounted on both sides of the slide block; the fixing screws are rotatably connected to the clamping blocks.

[0014] The advantages of this utility model are:

[0015] 1. The automatic explosion-proof installation and dismantling lifting device of this utility model is provided by setting up a cross-type lifting vehicle, a support platform, a vertical arm, a clamping screw, and a clamping block; the vertical arm, clamping screw, and clamping block are used to clamp and fix the explosion-proof device, and the cross-type lifting vehicle is used to lift and lower the support platform to complete the installation and dismantling of the explosion-proof device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0030] like Figures 1 to 3 As shown, an automatic explosion-proof installation and dismantling lifting device includes a cross-type lifting vehicle 1; a support platform 2 is fixedly connected to the top surface of the top plate of the cross-type lifting vehicle 1; an explosion-proof device 3 is placed on the top surface of the support platform 2; multiple vertical arms 4 are fixedly bolted to both sides of the top surface of the support platform 2; a clamping screw 5 is threadedly installed on the top of the vertical arm 4; a clamping block 6 is rotatably installed on one end of the clamping screw 5 near the explosion-proof device 3;

[0031] Specifically, the cross-type lifting vehicle 1 includes a base, with rollers rotatably mounted on both sides of the base, and a braking mechanism on the rollers to limit and fix the movement of the cross-type lifting vehicle 1; a cross-type lifting frame is provided inside the base, and one side of the cross-type lifting frame can slide and engage with the side wall of the base; a pair of hydraulic cylinders are provided inside the base, and the piston rod ends of the hydraulic cylinders are hinged to the sliding ends of the bottom of the cross-type lifting frame; a top plate is hinged to one pair of top ends of the cross-type lifting frame, and the other pair of top ends of the cross-type lifting frame is slidably connected to the top plate;

[0032] The top of the vertical arm 4 is provided with a threaded hole, and the clamping screw 5 is threaded into the inside of the threaded hole. The end of the clamping screw 5 away from the explosion-proof device 3 is provided with a handle.

[0033] When the explosion-proof device 3 is installed, the hydraulic cylinder of the cross-type lifting vehicle 1 is in the extended state, which causes the two sides of the bottom of the cross-type lifting frame to separate, causing the cross-type lifting frame to fold and retract, thereby driving the support platform 2 to descend in height.

[0034] Place the explosion-proof device 3 on the top center of the support platform 2, rotate the clamping screw 5 so that the clamping screw 5 moves toward the explosion-proof device 3, and push the clamping block 6 to press and contact the side of the explosion-proof device 3; then rotate the multiple clamping screws 5 on both sides in sequence so that the clamping blocks 6 on both sides press and contact the sides of the explosion-proof device 3 respectively, and fix the explosion-proof device 3 on the top center of the support platform 2.

[0035] The cross-type lifting vehicle 1 is moved to the installation position in the tunnel, and the shock wave receiver of the explosion-proof device 3 is oriented towards the potential explosion source. The cross-type lifting vehicle 1 is then fixed in place. The hydraulic cylinder of the cross-type lifting vehicle 1 retracts, causing the two sides of the bottom of the cross-type lifting frame of the cross-type lifting vehicle 1 to move closer together, so that the cross-type lifting frame of the cross-type lifting vehicle 1 unfolds upward, pushing the support platform 2 to rise in height, and lifting the explosion-proof device 3 to the top installation position in the tunnel. After the worker installs and fixes the explosion-proof device 3, the clamping screw 5 is rotated in the opposite direction, causing the clamping block 6 to move away from the explosion-proof device 3, and the explosion-proof device 3 is released. Finally, the cross-type lifting vehicle 1 is controlled to descend to the reset position.

[0036] When disassembling the explosion-proof device 3, the cross-type lifting vehicle 1 is moved to the top of the tunnel below the explosion-proof device 3, so that the middle of the support platform 2 is aligned with the explosion-proof device 3. The cross-type lifting vehicle 1 is controlled to lift the support platform 2 to a higher height, so that the middle of the top surface of the support platform 2 contacts the bottom of the explosion-proof device 3. At this time, the clamping screw 5 is rotated twice in sequence, pushing the clamping blocks 6 on both sides to clamp and fix the two sides of the explosion-proof device 3. Then, the fixing bolts of the explosion-proof device 3 are removed, so that the explosion-proof device 3 is removed from the top of the tunnel. Finally, the cross-type lifting vehicle 1 drives the support platform 2 to a lower height.

[0037] This completes the installation and disassembly of the explosion-proof device 3, reducing the number of workers, lowering the difficulty of installation and construction, and reducing the probability of the explosion-proof device 3 falling.

[0038] Furthermore, such as Figures 1 to 3 As shown, a bracket 7 is fixedly connected to the side of the vertical arm 4 away from the explosion-proof device 3; a sleeve 8 is fixedly connected to the top of the bracket 7; and the clamping screw 5 slides through the sleeve 8.

[0039] Specifically, the bracket 7 is fixed and locked to the upright arm 4 by bolts, and the sleeve 8 is aligned with the threaded hole of the upright arm 4;

[0040] When the clamping screw 5 moves along the threaded hole of the vertical arm 4, it moves along the sleeve 8. The sleeve 8 supports and limits the end of the clamping screw 5 away from the explosion-proof device 3, so that the clamping screw 5 always remains in a horizontal state. This reduces the pressure of the clamping screw 5 on the threaded hole of the vertical arm 4 caused by the weight of the explosion-proof device 3, thus reducing the damage to the threads. This improves the stability of the movement of the clamping screw 5 and improves the clamping and fixing effect on the explosion-proof device 3.

[0041] In some embodiments, such as Figure 1 , Figure 2 , Figures 4 to 7 As shown, a guide rail 9 is fixedly connected to the center of the top surface of the support platform 2; a plurality of slide blocks 10 are slidably installed on the guide rail 9; an mounting plate 11 is bolted to the top surface of the slide block 10; and a support plate 12 that contacts the bottom of the explosion-proof device 3 is hinged to the top surface of the mounting plate 11.

[0042] Specifically, the top surface of the slide 10 has screw holes on both sides, and the top surface of the mounting plate 11 has countersunk holes on both sides. Screws are installed inside the countersunk holes, and the bottom of the screws engages with the internal threads of the screw holes to fix and lock the slide 10 and the mounting plate 11.

[0043] Multiple support seats 13 are fixed in the middle of the top surface of the mounting plate 11; the top of the support seat 13 is provided with a groove; multiple rotating seats 14 are fixed in the middle of the bottom surface of the support plate 12, and the rotating seats 14 are located inside the groove of the support seat 13; a through hole is provided at the position where the rotating seat 14 overlaps with the support seat 13, and a hinge shaft is rotatably installed inside the through hole; by rotating the rotating seat 14 in the groove of the support seat 13, not only can the support plate 12 be rotated to change the angle, but the supporting force of the support plate 12 is also guaranteed.

[0044] When the explosion-proof device 3 is placed on top of the support platform 2, the bottom of the explosion-proof device 3 contacts the top surface of the support plate 12, causing the support plate 12 to rotate and fit against the outer wall of the explosion-proof device 3; by using multiple support plates 12 to effectively support different positions of the bottom of the explosion-proof device 3, the stability of the explosion-proof device 3 is improved.

[0045] Furthermore, such as Figures 4 to 7 As shown, multiple shims 15 are stacked between the slide block 10 and the mounting plate 11;

[0046] Specifically, the raised plate 15 has round holes on both sides, and the round holes correspond to the screw holes of the slide 10 and the countersunk holes on both sides of the mounting plate 11. Long screws pass through the countersunk holes of the mounting plate 11 and the round holes of the raised plate 15, and engage with the screw thread of the slide 10.

[0047] By fixing and stacking the shim plate 15 between the slide 10 and the mounting plate 11, the height of the lifting plate 12 is controlled, which makes it easier for the plate to lift different positions at the bottom of the explosion-proof device 3, thereby helping to keep the explosion-proof device 3 horizontally fixed and facilitating the installation of the explosion-proof device 3.

[0048] In some embodiments, such as Figures 4 to 8 As shown, multiple sleeve rods 16 are hinged to both sides of the mounting plate 11; multiple slide rods 17 are hinged to both sides of the support plate 12; the slide rods 17 are slidably installed inside the sleeve rods 16; multiple fastening screws 18 for fixing and locking the slide rods 17 are arranged around the top outer ring of the sleeve rods 16.

[0049] Specifically, the sleeve rod 16 is hinged to both sides of the mounting plate 11 via hinges, and the slide rod 17 is hinged to both sides of the support plate 12 via hinges; the top outer ring of the sleeve rod 16 is provided with multiple threaded holes, and the fastening screws 18 are threaded inside the threaded holes. By pressing the slide rod 17 against the outer wall of the slide rod 17 through the multiple fastening screws 18, the slide rod 17 is fixed inside the sleeve rod 16.

[0050] When the support plate 12 rotates to fit against the bottom outer wall of the explosion-proof device 3, the support plate 12 tilts, causing the slide rod 17 on the bottom side of the support plate 12 to slide into the inside of the sleeve rod 16, and the slide rod 17 on the top side of the support plate 12 to slide out and extend from the inside of the sleeve rod 16; then, the fastening screw 18 is tightened with a wrench to lock the slide rod 17 and the sleeve rod 16 in place; through the cooperation of the slide rods 17 on both sides and the sleeve rod 16, the two sides of the support plate 12 are supported and fixed, thereby further improving the support stability of the explosion-proof device 3.

[0051] In some embodiments, such as Figures 4 to 9 As shown, a rubber pad 19 is provided on the top surface of the tray 12;

[0052] Specifically, the top surface of the tray 12 is evenly provided with multiple convex mounting grooves, the bottom surface of the rubber pad 19 is fixed with multiple clips that match the mounting grooves, and the top surface of the rubber pad 19 is provided with anti-slip texture.

[0053] The rubber gasket 19 is fixedly installed on the top surface of the tray 12 by the locking strip on the bottom surface of the rubber gasket 19 cooperating with the mounting groove on the top surface of the tray 12, making it easy to replace the rubber gasket 19.

[0054] By using the rubber pad 19, not only is the impact force between the explosion-proof device 3 and the support plate 12 reduced, thus reducing damage to the explosion-proof device 3, but the friction between the explosion-proof device 3 and the support plate 12 is also increased, reducing the probability of the explosion-proof device 3 falling.

[0055] Furthermore, such as Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, clamping blocks 20 are slidably installed on both sides of the inner cavity of the slide block 10; fixing screws 21 are threadedly installed on both sides of the slide block 10; the fixing screws 21 are rotatably connected to the clamping blocks 20;

[0056] Specifically, the slide block 10 has storage slots on both sides of its inner cavity, and the top and bottom of the storage slots are provided with sliding grooves; the clamping block 20 is set inside the storage slot, and the top and bottom of the clamping block 20 are fixed with sliders that match the sliding grooves; the slide block 10 has threaded holes on both sides and in the middle of the storage slot that match the threads of the fixing screw 21; one end of the fixing screw 21 is rotatably connected to the middle of the clamping block 20 through a bearing, and the other end of the fixing screw 21 has an internal hexagonal groove;

[0057] After the slide block 10 is slid along the guide rail 9 and adjusted to a suitable position, the fixing screw 21 is turned with a hex wrench. The fixing screw 21 pushes the clamping block 20 close to the side of the compression guide rail 9. The clamping block 20 clamps the two sides of the guide rail 9 twice, fixing and locking the slide block 10 on the guide rail 9, thereby preventing the slide block 10 from sliding and further improving the fixing stability of the explosion-proof device 3.

[0058] Working principle: When the explosion-proof device 3 is installed, the hydraulic cylinder of the cross-type lifting vehicle 1 is in the extended state, which separates the two sides of the bottom of the cross-type lifting frame, causing the cross-type lifting frame to fold and retract, thereby driving the support platform 2 to descend in height.

[0059] When the explosion-proof device 3 is placed on top of the support platform 2, the bottom of the explosion-proof device 3 contacts the top surface of the support plate 12, causing the support plate 12 to rotate and fit against the outer wall of the explosion-proof device 3; the support plate 12 tilts, causing the slide rod 17 on the bottom side of the support plate 12 to slide into the inside of the sleeve rod 16, and the slide rod 17 on the top side of the support plate 12 to slide out and extend from the inside of the sleeve rod 16; then, the fastening screw 18 is tightened with a wrench to lock and fix the slide rod 17 and the sleeve rod 16; the two sides of the support plate 12 are supported and fixed by the cooperation of the slide rod 17 and the sleeve rod 16 on both sides;

[0060] Rotate the clamping screw 5 so that it moves toward the explosion-proof device 3, pushing the clamping block 6 to press and contact the side of the explosion-proof device 3; then rotate the multiple clamping screws 5 on both sides in sequence so that the clamping blocks 6 on both sides press and contact the sides of the explosion-proof device 3 respectively, fixing the explosion-proof device 3 to the center of the top surface of the support platform 2.

[0061] The cross-type lifting vehicle 1 is moved to the installation position in the tunnel, and the shock wave receiver of the explosion-proof device 3 is oriented towards the potential explosion source. The cross-type lifting vehicle 1 is then fixed in place. The hydraulic cylinder of the cross-type lifting vehicle 1 retracts, causing the two sides of the bottom of the cross-type lifting frame of the cross-type lifting vehicle 1 to move closer together, so that the cross-type lifting frame of the cross-type lifting vehicle 1 unfolds upward, pushing the support platform 2 to rise in height, and lifting the explosion-proof device 3 to the top installation position in the tunnel. After the worker installs and fixes the explosion-proof device 3, the clamping screw 5 is rotated in the opposite direction, causing the clamping block 6 to move away from the explosion-proof device 3, and the explosion-proof device 3 is released. Finally, the cross-type lifting vehicle 1 is controlled to descend to the reset position.

[0062] When disassembling the explosion-proof device 3, the cross-type lifting vehicle 1 is moved to the top of the tunnel below the explosion-proof device 3, so that the middle of the support platform 2 is aligned with the explosion-proof device 3. The cross-type lifting vehicle 1 is controlled to lift the support platform 2 to a higher height, so that the middle of the top surface of the support platform 2 contacts the bottom of the explosion-proof device 3. At this time, the clamping screw 5 is rotated twice in sequence, pushing the clamping blocks 6 on both sides to clamp and fix the two sides of the explosion-proof device 3. Then, the fixing bolts of the explosion-proof device 3 are removed, so that the explosion-proof device 3 is removed from the top of the tunnel. Finally, the cross-type lifting vehicle 1 drives the support platform 2 to a lower height.

[0063] This completes the installation and disassembly of the explosion-proof device 3, reducing the number of workers, lowering the difficulty of installation and construction, and reducing the probability of the explosion-proof device 3 falling.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
