Description

Technical Field

[0001] This invention belongs to the technical field of rapid drug loading equipment, specifically a rapid drug loading device based on an arch frame installation machine and its usage method. Background Technology

[0002] Due to the harshness of the high-altitude environment, workers find it difficult to adapt physically and perform high-intensity work during high-altitude tunnel construction. Therefore, higher requirements are placed on the mechanization of high-altitude tunnel construction. In current drill-and-blast tunnel mechanization equipment, the charging line has become a bottleneck in mechanized construction. Charging is usually still carried out using traditional trolley operations, resulting in low construction efficiency and high platform costs.

[0003] Publication No. CN215984246U discloses an explosive loading device, including a transport vehicle and supporting equipment. The supporting equipment has a feeder mounted on its basket. The transport vehicle includes a body and a hydraulic system and a delivery system mounted on the body. The delivery system is detachably connected to the delivery pipe on the feeder. The hydraulic system is detachably connected to the feeder via hydraulic lines, thereby controlling the feeder's movement. This invention addresses the diverse types of construction equipment used in tunnel and other engineering projects by combining a transport vehicle with supporting equipment (such as a rock drilling rig) for explosive loading. The loading device delivers emulsion explosives, enabling mechanized and automated loading operations. This promotes seamless integration of drilling and loading (drilling and blasting) processes, solving the problems of long equipment transfer times, long process switching times, and low overall economic efficiency caused by the need for loading equipment to enter the site after drilling equipment has been removed.

[0004] In the above-mentioned scheme, the loading process requires operators to work on the hoist basket of the rock drilling rig to extend the delivery pipe into the borehole and complete the hole alignment. Before use, the hoist basket needs to be transported into the tunnel and then assembled onto the grabbing mechanical arm of the rock drilling rig. Due to the limited space and complex terrain inside the tunnel, the existing hoist basket occupies a large space and is relatively cumbersome to use, which is not conducive to the flexible movement and adjustment of the hoist basket in the tunnel. Therefore, the present invention provides a rapid loading device based on an arch frame installation machine and its usage method. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a rapid loading device based on an arch frame installation machine, including a main platform, two sets of guardrails symmetrically arranged on the main platform, two sets of plate sleeves symmetrically inserted at both ends of the main platform, the plate sleeves being inserted into insert plates, the insert plates being fixedly connected to the side guardrails, six sets of telescopic rods symmetrically arranged on one side of the side guardrails, an auxiliary installation mechanism being set on one set of guardrails, two sets of hooks symmetrically arranged on the auxiliary installation mechanism, the telescopic rods being composed of pipe sleeves and pull rods, three sets of insertion holes being opened at the end of the guardrails, the pipe sleeves being inserted into the insertion holes, and one end of the pull rod being fixedly connected to the side guardrails;

[0007] Compared with existing technologies, this device can be unfolded and retracted. When retracted, the device becomes smaller, thereby reducing the space occupied by the device in the tunnel and making it easier for the device to move in the tunnel.

[0008] Preferably, the auxiliary installation mechanism includes: two sets of housings, the housings being fixedly installed on the main platform, a drive shaft being rotatably installed between the two sets of housings, four sets of reels symmetrically arranged at both ends of the drive shaft, a steel wire rope wound on the reels, a fixing block fixedly installed on the steel wire rope, a hook installed on the fixing block, a support plate welded inside the housing, two sets of shafts symmetrically screwed onto the support plate, two sets of guide wheels symmetrically screwed onto both ends of a set of shafts, the guide wheels being rotatably connected to the steel wire rope, a first worm gear fixedly installed at the end of the drive shaft, and a first worm gear meshing with the first worm gear, the first worm gear being screwed onto a set of housings;

[0009] By straightening the steel wire rope, not only is the position of the device relative to the lifting robotic arm corrected, but the device is also installed. The structure is simple and easy to operate, making it convenient for workers to install the device.

[0010] Preferably, during the winding and unwinding of the wire rope on the reel, the wire rope is clamped between a set of shafts and guide wheels. The wire rope will drive shafts and two sets of guide wheels to rotate. The guide wheels are set in coordination with shafts to not only limit the movement of the wire rope, but also guide its movement.

[0011] Preferably, the fixing block includes: a block body, a steel wire rope fixedly connected to the block body, a hook fixedly connected to the block body, a guide groove opened on one side of the block body, a positioning pin movably inserted into the guide groove, a movable threaded sleeve movably installed inside the positioning pin, a first spring sleeved on the movable threaded sleeve, a screw rod screwed to the movable threaded sleeve, and several sets of push plates inserted into the positioning pin at equal angles, two sets of limiting grooves symmetrically opened on one side of a set of guardrails, the positioning pin inserted into the limiting groove, several sets of movable holes opened at equal angles on the positioning pin, the push plates slidingly connected to the movable holes, several sets of rectangular grooves set at equal angles on the threaded sleeve, a pin shaft set in the rectangular groove, an oblique sliding groove opened on the push plate, and the pin shaft slidingly connected to the oblique sliding groove;

[0012] As several sets of push plates move simultaneously, they play a certain corrective role in the alignment of the positioning pin and the limiting groove. The coordinated design of the push plates, positioning pins, and limiting grooves enables the push plates and positioning pins to support the device, thereby reducing the load on the wire rope and improving its service life.

[0013] Preferably, a protective cover assembly is provided on a set of guardrails. The protective cover assembly includes a support plate, a docking groove is provided on the set of guardrails, the lower end of the support plate is inserted into the docking groove, and the upper end of the support plate is provided with the main body of the protective cover.

[0014] The main body of the protective shield provides protection for workers from above, preventing them from being injured by falling objects.

[0015] Preferably, the protective cover body includes: a main cover body, a support plate with the main cover body inserted into its upper end, two sets of first cover bodies symmetrically arranged at both ends of the main cover body, a second cover body arranged at one end of the first cover body, two sets of screw-connecting shafts fixedly welded to both sides of the other end of the first cover body, the screw-connecting shafts being screwed to the main cover body, a second worm gear fixedly installed on one set of screw-connecting shafts, a second worm gear meshing with the second worm gear, the second worm gear being screwed to one side of the main cover body, and a linkage mechanism connecting the screw-connecting shafts. The linkage mechanism is used to drive the second cover body to fold and flip. The linkage mechanism includes: a screw-connecting sleeve, one end of which is screwed to the screw-connecting shaft. Synchronous belt, used for transmission between the swivel sleeve and the pulley; rectangular shaft movably installed in the swivel sleeve; rectangular shaft movably inserted into the swivel shaft; drive plate fixedly connected to the rectangular shaft; pressure rod fixedly welded to one side of the drive plate; two sets of convex shafts fixedly welded to the outer ring of the drive plate; second spring sleeved on the rectangular shaft; and pressure block provided at the end of the pressure rod, pressure block fixedly welded to the main cover; pulley end screwed to the second cover; pulley end fixedly connected to the inner wall of the first cover; two sets of spiral grooves opened on the swivel sleeve; convex shaft slidably connected to the spiral grooves.

[0016] The second cover folds onto the first cover, and the first cover, together with the second cover, folds onto the main cover, thus reducing the overall volume of the protective cover.

[0017] A rapid loading method, employing the aforementioned rapid loading equipment based on an arch-frame installation machine, includes the following steps:

[0018] S1. Construction preparation: The loading team, blasting company, and equipment arrive on site.

[0019] S2. Install the extension baskets at each part: Install the middle basket by placing it horizontally. The robot arm controls the trolley to grab the robotic arm and extend it to one side of the middle basket. Then, manually install the middle basket onto the robotic arm. Expand the left and right small baskets and install their protective devices. Insert the iron pins welded to the outer guardrail into the steel sleeves welded to the existing guardrail. The installation of the small basket protective devices is now complete.

[0020] S3. Preparation for loading explosives: Workers from each division place the explosives and detonators on the suspended platform. Workers enter the suspended platform, fasten their safety ropes, and connect the safety ropes to a secure point on the suspended platform.

[0021] S4. Loading Operation: The machine operator lifts each basket to the designated construction area, moves the basket according to the instructions of the loading worker, and carries out the loading operation.

[0022] S5. Wire Connection: After the explosive loading is completed, the workers stand on the basket to connect the electronic detonators.

[0023] S6. Disassembly and Folding of the Suspended Basket: After the loading and wiring operations are completed and inspected by the blasting company, the loading workers leave the site. The machine operator lowers the suspended basket, disassembles and repositions the safety devices of the central suspended basket and the left and right smaller suspended baskets, and folds the left and right smaller suspended baskets. The folded boom is then retrieved.

[0024] S7. Evacuation Blasting: Machinery, equipment, and workers are evacuated from the site, and blasting operations are carried out by a blasting company.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. Pulling the two sets of side guardrails in opposite directions causes the side guardrails to move the plate sleeve and the insert plate. The plate sleeve slides outward along the inner cavity of the main platform, and the insert plate slides outward along the plate sleeve, so that the plate sleeve and the insert plate extend outward simultaneously. At the same time, the side guardrails pull the tube sleeve and the pull rod. The tube sleeve slides along the insertion hole, and the pull rod slides along the tube sleeve, so that the telescopic rod is pulled out from the insertion hole and the telescopic rod is extended, thus unfolding the entire device. Conversely, pushing the two sets of side guardrails in opposite directions causes the device to retract. Compared with the existing technology, since this device can be unfolded and retracted, the device volume becomes smaller after retraction, thereby reducing the space occupied by the device in the tunnel and facilitating the movement of the device in the tunnel.

[0027] 2. Control the lifting robotic arm so that the connecting slot on the lifting robotic arm is positioned above the hook side. Then, rotate the first worm gear. As the first worm gear rotates, the first worm wheel drives the transmission shaft and four sets of reels to rotate together. As the reels rotate, the steel wire rope wound on the reels is pulled out. At this time, the steel wire rope is relatively loose, and the operator can move the fixing block along with the hook in any direction until the hook can engage in the connecting slot on the lifting robotic arm. Then, rotate the first worm gear again to make the four sets of reels rotate back and begin to tighten the steel wire rope. As the steel wire rope tightens, the fixing block begins to move towards the guardrail. Since the hook is engaged with the lifting robotic arm, the entire device moves towards the lifting robotic arm until the steel wire rope is taut. At the same time, the fixing block is pressed tightly against the guardrail again. By tautening the steel wire rope, not only is the position of the device relative to the lifting robotic arm corrected, but the device is also installed. The structure is simple and easy to operate, making it convenient for operators to install the device.

[0028] 3. The movable screw drives several sets of pins to slide along the corresponding inclined slide grooves, and the pins press against the groove walls, causing the push plate to move along the movable hole toward the inner wall of the limiting groove until the push plate is in contact with the inner wall of the limiting groove. Since several sets of push plates move at the same time, they play a certain corrective role in the alignment of the positioning pin and the limiting groove. The coordinated setting of the push plate, positioning pin, and limiting groove enables the push plate and positioning pin to support the device, thereby reducing the load on the wire rope and improving the service life of the wire rope.

[0029] 4. The rotating shaft drives the rectangular shaft, drive plate, and pressure rod to rotate together. The end of the pressure rod slides against the inclined surface, while the inclined surface continuously squeezes the pressure rod, causing the pressure rod to push the drive plate to slide along the inner cavity of the rotating sleeve and compress the second spring. At the same time, the drive plate drives the two sets of convex shafts to slide along the corresponding spiral grooves. Under the guidance of the spiral grooves, the rotating sleeve rotates. The rotating rotating sleeve causes the pulley to rotate through the synchronous belt. The pulley drives the second cover to fold and flip towards the first cover. Therefore, the second cover folds onto the first cover, and the first cover together with the second cover folds onto the main cover, reducing the volume of the entire protective cover.

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0043] Example 1

[0044] like Figure 1 and Figure 2 As shown in the figure, a rapid loading device based on an arch frame installation machine according to an embodiment of the present invention includes a main platform 1, two sets of guardrails 2 symmetrically arranged on the main platform 1, two sets of plate sleeves 3 symmetrically inserted at both ends of the main platform 1, plate sleeves 3 inserted into insert plates 4, insert plates 4 fixedly connected to side guardrails 5, six sets of telescopic rods 6 symmetrically arranged on one side of the side guardrails 5, an auxiliary installation mechanism 7 is set on one set of guardrails 2, two sets of hooks 8 are symmetrically arranged on the auxiliary installation mechanism 7, the telescopic rods 6 are composed of pipe sleeves 601 and pull rods 602, three sets of insertion holes 201 are opened at the end of the guardrails 2, the pipe sleeves 601 are inserted into the insertion holes 201, and one end of the pull rods 602 is fixedly connected to the side guardrails 5.

[0045] Specifically, four steel cable loops are welded to the two sets of side guardrails 5. The steel cables on these loops are then connected to the designated positions on the robotic arm to form a secondary safety measure. Before using the device, it is placed horizontally in front of the robotic arm control trolley. The robotic arm control trolley is then operated to grip the robotic arm, causing the connecting slot on the gripping robotic arm to insert into the connecting hook 8 on the device. The robotic arm is then lifted upwards, completing the installation. Next, the two sets of side guardrails 5 are pulled in opposite directions. The side guardrails 5 move the plate sleeve 3 and the insert plate 4. The plate sleeve 3 slides outwards along the inner cavity of the main platform 1, and the insert plate 4... Slide the sleeve 3 outwards, causing the sleeve 3 and the insert plate 4 to extend outwards simultaneously. At the same time, the side guardrail 5 pulls the sleeve 601 and the pull rod 602. The sleeve 601 slides along the insertion hole 201, and the pull rod 602 slides along the sleeve 601, causing the telescopic rod 6 to be pulled out of the insertion hole 201 and extended, thus unfolding the entire device. Conversely, push the two sets of side guardrails 5 in opposite directions to retract the device. Compared with the prior art, since this device can be unfolded and retracted, the device volume becomes smaller after retraction, thereby reducing the space occupied by the device in the tunnel and facilitating the movement of the device in the tunnel.

[0046] like Figure 2 and Figure 3 As shown, the auxiliary installation mechanism 7 includes: two sets of housings 701, the housings 701 being fixedly installed on the main platform 1; a drive shaft 702 being rotatably installed between the two sets of housings 701; four sets of reels 703 symmetrically arranged at both ends of the drive shaft 702; steel wire ropes 704 wound on the reels 703; fixing blocks 706 fixedly installed on the steel wire ropes 704; hooks 8 installed on the fixing blocks 706; a support plate 710 welded inside the housings 701; two sets of shafts 707 symmetrically screwed onto the support plates 710; two sets of guide wheels 708 symmetrically screwed onto both ends of one set of shafts 707; the guide wheels 708 rotatably connecting to the steel wire ropes 704; a first worm gear 709 fixedly installed at the end of the drive shaft 702; and a first worm 705 meshing with the first worm gear 709; the first worm gear 709 being screwed onto one set of housings 701.

[0047] Specifically, in the initial state, the fixing block 706 is tightly attached to the guardrail 2, and the steel wire rope 704 is taut. During the process of inserting the connecting slot on the lifting robotic arm into the hook 8, the driver in the control trolley cannot observe the position between the lifting robotic arm and the hook 8. Therefore, the driver needs to coordinate with the commanding personnel on the side, which requires a high degree of cooperation between the commanding personnel and the driver. Secondly, the connecting slot needs to be precisely inserted into the hook 8. Under the commanding personnel, the driver may need to repeat this process multiple times to achieve this, which requires a high level of operating skill from the driver. This makes the installation of the device on the robotic arm difficult and inefficient. Therefore, when installing the device, the lifting robotic arm is controlled so that the connecting slot on the lifting robotic arm is located above the hook 8 on one side. Then, the first worm gear 705 is rotated. As the first worm gear 705 rotates, the first worm wheel 709 drives the transmission shaft 702 along with the four sets of reels 7. 03 rotates together. As the reel 703 rotates, the wire rope 704 wound on the reel 703 is pulled out. At this time, the wire rope 704 is relatively loose. The operator can move the fixing block 706 together with the hook 8 in any direction until the hook 8 can be engaged in the connecting slot on the lifting robot arm. Then, the first worm gear 705 is rotated again, causing the four sets of reels 703 to rotate back and begin to tighten the wire rope 704. As the wire rope 704 is continuously tightened, the fixing block 706 begins to move towards the guardrail 2. Since the hook 8 is engaged on the lifting robot arm, the entire device moves towards the lifting robot arm until the wire rope 704 is taut. At the same time, the fixing block 706 is pressed tightly against the guardrail 2 again. By tautening the wire rope 704, not only is the position of the device relative to the lifting robot arm corrected, but the device is also installed. The structure is simple and easy to operate, making it convenient for operators to install the device.

[0048] Furthermore, during the winding and unwinding of the wire rope 704 by the reel 703, the wire rope 704 is clamped between a set of shafts 707 and guide wheels 708. The wire rope 704 will drive the shafts 707 and the two sets of guide wheels 708 to rotate. The guide wheels 708 are set in coordination with the shafts 707, which not only limit the movement of the wire rope 704, but also guide the movement of the wire rope 704.

[0049] like Figures 3 to 6As shown, the fixing block 706 includes: a block body 7061, a steel wire rope 704 fixedly connected to the block body 7061, a hook 8 fixedly connected to the block body 7061, a guide groove 7062 opened on one side of the block body 7061, a positioning pin 7063 movably inserted into the guide groove 7062, a movable threaded sleeve 7064 movably installed inside the positioning pin 7063, a first spring 7065 sleeved on the movable threaded sleeve 7064, a screw 7066 screwed onto the movable threaded sleeve 7064, and a screw rod 7066 inserted at equal angles into the guide groove 7062. The positioning pin 7063 has several sets of push plates 7067. Two sets of limiting grooves 202 are symmetrically opened on one side of a set of guardrails 2. The positioning pin 7063 is inserted into the limiting groove 202. Several sets of movable holes 631 are opened at equal angles on the positioning pin 7063. The push plate 7067 is slidably connected to the movable holes 631. Several sets of rectangular grooves 641 are set at equal angles on the screw sleeve. The pin 642 is set in the rectangular groove 641. The push plate 7067 has an oblique sliding groove 671. The pin 642 is slidably connected to the oblique sliding groove 671.

[0050] Specifically, since the workers are standing inside the device, the weight of both the workers and most of the device is on the wire rope 704, resulting in a heavy load on the wire rope 704. Over time, this can cause deformation of the wire rope 704, reducing its service life. Therefore, after the device is installed on the lifting robotic arm, an Allen wrench is inserted into the limiting groove 202, and the screw 7066 is turned. As the screw 7066 rotates, the movable sleeve 7064 will drive the first spring 7065, along with the positioning pin 7063, into the limiting groove 202. The outer diameter of the positioning pin 7063 is smaller than the inner diameter of the limiting groove 202. Considering the slight deformation of the wire rope 704 under load, even if there is a slight error in the alignment of the positioning pin 7063 with the limiting groove 202, the positioning pin 7063 can still be smoothly inserted into the limiting groove 202 until the positioning pin... When 7063 is blocked and cannot move, the movable sleeve 7064 will continue to slide along the inner cavity of the positioning pin 7063 and compress the first spring 7065. At the same time, the movable sleeve 7064 drives several sets of pins 642 to slide along the corresponding inclined grooves 671, and the pins 642 press against the groove wall of the inclined groove 671, causing the push plate 7067 to move along the movable hole 631 toward the inner wall of the limiting groove 202 until the push plate 7067 fits against the inner wall of the limiting groove 202. Since several sets of push plates 7067 move at the same time, they play a certain corrective role in the alignment of the positioning pin 7063 and the limiting groove 202. The coordinated setting of the push plate 7067, the positioning pin 7063, and the limiting groove 202 enables the push plate 7067 and the positioning pin 7063 to support the device, thereby reducing the load on the wire rope 704 and improving the service life of the wire rope 704.

[0051] like Figure 7As shown, a set of guardrails 2 is provided with a protective cover assembly 9. The protective cover assembly 9 includes a support plate 901. A docking groove 203 is opened on the set of guardrails 2. The lower end of the support plate 901 is inserted into the docking groove 203. The upper end of the support plate 901 is provided with a protective cover body 902.

[0052] Specifically, when workers are working on the device inside the tunnel, there are no protective measures above the device, and falling mud and rocks from the tunnel ceiling can easily injure them. Therefore, before workers enter the device, the support plate 901 is inserted into the docking slot 203 on a set of guardrails 2, and then the main body of the protective cover 902 is inserted into the upper end of the support plate 901. The main body of the protective cover 902 provides protection above the workers and prevents them from being injured by falling debris.

[0053] like Figures 8 to 10 As shown, the protective cover body 902 includes: a main cover 9021, a support plate 901 with its upper end inserted into the main cover 9021, two sets of first cover bodies 9022 symmetrically arranged at both ends of the main cover 9021, a second cover body 9023 arranged at one end of the first cover body 9022, two sets of screw shafts 9024 fixedly welded to both sides of the other end of the first cover body 9022, the screw shafts 9024 being screwed to the main cover 9021, a second worm gear 9025 fixedly installed on one set of screw shafts 9024, a second worm 9026 meshing with the second worm gear 9025, the second worm 9026 being screwed to one side of the main cover 9021, and a linkage mechanism 9027 connecting the screw shafts 9024. The linkage mechanism 9027 is used to drive the second cover body 9023 to fold and flip. The linkage mechanism 9027 includes: a screw sleeve 271, one end of which is screwed to a screw... The system includes a connecting shaft 9024, a timing belt 272 for transmission between the connecting sleeve 271 and the pulley 273, a rectangular shaft 274 movably installed inside the connecting sleeve 271, the rectangular shaft 274 movably inserted into the connecting shaft 9024, a drive plate 275 fixedly connected to the rectangular shaft 274, a pressure rod 276 fixedly welded to one side of the drive plate 275, two sets of convex shafts 277 fixedly welded to the outer ring of the drive plate 275, a second spring 278 sleeved on the rectangular shaft 274, and a pressure block 279 provided at the end of the pressure rod 276, the pressure block 279 fixedly welded to the main cover 9021, the end of the pulley 273 screwed to the second cover 9023, the end of the pulley 273 fixedly connected to the inner wall of the first cover 9022, two sets of spiral grooves 711 opened on the connecting sleeve 271, and the convex shafts 277 slidably connected to the spiral grooves 711.

[0054] Specifically, the pressure block 279 is provided with an inclined surface 791. Because the main body of the protective cover 902 is relatively large, its movement is not flexible enough, making it inconvenient for workers to install, disassemble, and move it. Therefore, when disassembling the main body of the protective cover 902, the second worm gear 9026 is rotated. The second worm gear 9026 drives two sets of second worm wheels 9025 to rotate, which in turn drives two sets of screw shafts 9024 and two sets of first cover bodies 9022 to rotate, causing the two sets of first cover bodies 9022 to fold towards the main cover body 9021. Simultaneously, the screw shafts 9024 drive the rectangular shaft 274, drive plate 275, and pressure rod 276 to rotate together. The end of the pressure rod 276 is attached to the inclined surface 791. 1. Sliding, while the inclined surface 791 continuously squeezes the pressure rod 276, causing the pressure rod 276 to push the drive plate 275 to slide along the inner cavity of the screw sleeve 271 and compress the second spring 278. At the same time, the drive plate 275 drives the two sets of convex shafts 277 to slide along the corresponding spiral grooves 711. Under the guidance of the spiral grooves 711, the screw sleeve 271 rotates. The rotating screw sleeve 271 causes the pulley 273 to rotate through the synchronous belt 272. The pulley 273 drives the second cover 9023 to fold and flip towards the first cover 9022. Therefore, the second cover 9023 is finally folded onto the first cover 9022. The first cover 9022 and the second cover 9023 are folded onto the main cover 9021, reducing the volume of the entire protective cover body 902.

[0055] Example 2

[0056] A rapid loading method, employing the aforementioned rapid loading equipment based on an arch-frame installation machine, includes the following steps:

[0057] S1. Construction preparation: The loading team, blasting company, and equipment arrive on site.

[0058] S2. Install the extension baskets at each part: Install the middle basket by placing it horizontally. The robot arm controls the trolley to grab the robotic arm and extend it to one side of the middle basket. Then, manually install the middle basket onto the robotic arm. Expand the left and right small baskets and install their protective devices. Insert the iron pins welded to the outer guardrail into the steel sleeves welded to the existing guardrail. The installation of the small basket protective devices is now complete.

[0059] S3. Preparation for loading explosives: Workers from each division place the explosives and detonators on the suspended platform. Workers enter the suspended platform, fasten their safety ropes, and connect the safety ropes to a secure point on the suspended platform.

[0060] S4. Loading Operation: The machine operator lifts each basket to the designated construction area, moves the basket according to the instructions of the loading worker, and carries out the loading operation.

[0061] S5. Wire Connection: After the explosive loading is completed, the workers stand on the basket to connect the electronic detonators.

[0062] S6. Disassembly and Folding of the Suspended Basket: After the loading and wiring operations are completed and inspected by the blasting company, the loading workers leave the site. The machine operator lowers the suspended basket, disassembles and repositions the safety devices of the central suspended basket and the left and right smaller suspended baskets, and folds the left and right smaller suspended baskets. The folded boom is then retrieved.

[0063] S7. Evacuation blasting: Machinery, equipment, and workers are evacuated from the site, and blasting operations are carried out by a blasting company.

[0064] Working principle: Control the lifting robotic arm so that the connecting slot on the lifting robotic arm is positioned above the hook 8 on one side. Then rotate the first worm gear 705. As the first worm gear 705 rotates, the first worm wheel 709 drives the transmission shaft 702 and the four sets of reels 703 to rotate together. As the reels 703 rotate, the wire rope 704 wound on the reels 703 is pulled out. At this time, the wire rope 704 is relatively loose, and the operator can move the fixing block 706 along with the hook 8 in any direction until the hook 8 can be engaged in the connecting slot on the lifting robotic arm. Then rotate the first worm gear 705 again to make the four sets of reels 703 rotate back and begin to tighten the wire rope 704. As the wire rope 704 is continuously tightened, the fixing block 706 begins to move towards the guardrail. 2. Moving to one side, since the hook 8 is engaged with the gripping robotic arm, the entire device moves towards the gripping robotic arm until the wire rope 704 is taut. Then, insert the Allen wrench into the limiting groove 202 and turn the screw 7066. As the screw 7066 rotates, the movable sleeve 7064 will drive the first spring 7065 along with the positioning pin 7063 to insert into the limiting groove 202 until the positioning pin 7063 is blocked and cannot move. At this time, the movable sleeve 7064 will continue to slide along the inner cavity of the positioning pin 7063 and compress the first spring 7065. At the same time, the movable sleeve 7064 will drive several sets of pins 642 to slide along the corresponding inclined slide groove 671, and the pins 642 will press against the groove wall of the inclined slide groove 671, causing the push plate 7067 to move along the movable hole. 631 moves towards the inner wall of the limiting groove 202 until the push plate 7067 fits against the inner wall of the limiting groove 202. Then, it pulls the two sets of side guardrails 5 in the opposite direction. The side guardrails 5 drive the plate sleeve 3 and the insert plate 4. The plate sleeve 3 slides outward along the inner cavity of the main platform 1, and the insert plate 4 slides outward along the plate sleeve 3, so that the plate sleeve 3 and the insert plate 4 extend outward simultaneously. At the same time, the side guardrails 5 pull the tube sleeve 601 and the pull rod 602. The tube sleeve 601 slides along the insertion hole 201, and the pull rod 602 slides along the tube sleeve 601, so that the telescopic rod 6 is pulled out from the insertion hole 201 and the telescopic rod 6 is extended, realizing the unfolding of the entire device. When disassembling the main body 902 of the protective cover, the second worm gear 9026 is rotated. The second worm gear 9026 will drive the two sets of second worm wheels 9025 to rotate. Wheel 9025 drives two sets of rotating shafts 9024 and two sets of first covers 9022 to rotate, causing the two sets of first covers 9022 to fold towards the main cover 9021. At the same time, the rotating shafts 9024 drive the rectangular shaft 274, drive plate 275, and pressure rod 276 to rotate together. The end of the pressure rod 276 slides against the inclined surface 791, while the inclined surface 791 continuously squeezes the pressure rod 276, causing the pressure rod 276 to push the drive plate 275 to slide along the inner cavity of the rotating sleeve 271 and compress the second spring 278. At the same time, the drive plate 275 drives two sets of convex shafts 277 to slide along the corresponding spiral grooves 711. Under the guidance of the spiral grooves 711, the rotating sleeve 271 rotates. The rotating sleeve 271 rotates the pulley 273 through the synchronous belt 272.The pulley 273 drives the second cover 9023 to fold and flip towards the first cover 9022.
