[0006] Furthermore, an L-shaped connecting plate is fixedly provided on the top side of the sliding rod, and a connecting strap is fixedly provided on the bottom side of the L-shaped connecting plate.

[0007] Furthermore, the placement frame has sliding grooves on both sides of the front side, and a slotted slide is slidably arranged inside the sliding groove. A connecting bent rod is rotatably arranged on the inner side of the front end of the slotted slide, and a connecting sleeve is fixedly arranged on the bottom side of the connecting drawstring, and the connecting bent rod is rotatably sleeved inside the connecting sleeve.

[0008] Furthermore, the sliding grooves provided on the lower sides of the front and rear sides of the placement frame are respectively provided with a first limiting column and a second limiting column, and the length of the first limiting column is greater than that of the second limiting column.

[0009] Furthermore, the rear side of the slotted slide plate is forked, and the first limiting column and the second limiting column are arranged on the inner side of the fork of the slotted slide plate.

[0010] Furthermore, a third sliding groove is provided on the upper front side of the placement frame, and the connecting strap slides inside the third sliding groove.

[0011] Furthermore, the dust suction mechanism includes a shell, two dust collecting frames are slidably arranged on the inner side of the shell, a fan is fixedly arranged on the top side of the shell, and a dust suction port is fixedly arranged on the bottom side of the shell, collection ports are opened on the top and bottom sides of the two dust collecting frames, and a second slide groove is fixedly arranged on the rear side of the dust collecting frame.

[0012] Furthermore, a first slide groove is fixedly provided on the upper front side of the inner wall of the shell, fixed plates are fixedly provided on both sides of the inner side of the first slide groove, an opening is opened on the top side of the first slide groove, a spring is fixedly provided on the inner side of the fixed plate, a sliding plate is fixedly provided on one side of the spring, and one side of the sliding plate is provided as an inclined plate.

[0013] Furthermore, a limit block is fixedly provided at the lower front side of the inner wall of the shell, a transmission plate is slidably provided inside the limit block, an angled top plate is fixedly provided at the upper sides of the transmission plate, and curved connecting blocks are fixedly provided at both sides of the bottom side of the transmission plate.

[0014] Furthermore, a first construction platform, a second construction platform and a third construction platform are respectively arranged on opposite sides of the plurality of side I-beams, a plurality of climbing ladders are symmetrically arranged on the front top sides of the two bottom I-beams, the third construction platform is provided with holes, one of the climbing ladders is arranged in the hole of the third construction platform, and the bottom side of the climbing ladder is arranged on the top side of the second construction platform.

[0015] By adopting the above structure, when it is necessary to move the position of the drilling and blasting trolley, the staff raises the position of the lifting plate by the forward and reverse motor in the lifting brake mechanism. At this time, the drilling and blasting trolley can be quickly moved through the solid rubber wheels by manpower and the motor, making the working process of the drilling and blasting trolley more flexible. When the drilling and blasting trolley is working, the position of the lifting plate is lowered by the forward and reverse motor. During the continuous descending process, the brake spring piece in the slotted plate and the solid rubber wheel are in contact, so that the solid rubber wheel cannot rotate. When the lifting plate continues to descend, the brake spring piece and the solid rubber The contact area of ​​the wheel gradually increases, improving the fixing effect of the solid rubber wheel. Then, the side of the brake spring that is not in contact with the solid rubber wheel contacts the sliding rod, pushing the sliding rod upward. Then, the sliding rod moves the L-shaped connecting plate and the connecting strap upward, and pulls the connecting sleeve on the lower side of the connecting strap. At the same time, the connecting bent rod inside the connecting sleeve and the slotted slide plate on one side of the connecting bent rod are pulled out of the sliding groove. At this time, the brake block inside the placement frame will fall off, making the solid rubber wheel unable to rotate. The solid rubber wheel is fixed with the brake spring to ensure that the drilling and blasting trolley is displaced during work.

[0016] At the same time, when the lifting plate descends, the transmission plate is brought down through two curved connecting blocks arranged on the top side of the lifting plate, and the angled top plates on both sides of the transmission plate are brought down when descending, and then the sliding plate is pulled back to its original position by the spring. When the sliding plate is reset, it will fall off from the second sliding groove, so that the second sliding groove on the rear side of the dust collecting frame is no longer restricted by the sliding plate, making it easier for the staff to take out the dust collecting frame from the inside of the shell and clean the inside of the dust collecting frame.

[0017] In summary, the staff controls the lifting brake mechanism, and uses the lifting plate to fix the solid rubber wheel, and uses the brake block to fix the solid rubber wheel for the second time, so that the drilling and blasting machine is more stable when working. At the same time, during the lowering process of the lifting plate, the dust collection frame in the dust suction mechanism is more convenient to disassemble and replace, thereby improving the dust removal effect. While ensuring the safety of construction workers, it reduces the impact of dust on the construction workers' bodies. At the same time, the solid rubber wheels allow the drilling and blasting trolley to move quickly, thereby improving the flexibility of the drilling and blasting trolley.

DETAILED DESCRIPTION

[0031] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] See also Figure 1-Figure 3 As shown, a fast-moving drilling and blasting trolley comprises: a plurality of side I-beams 1 and two bottom I-beams 7, the side I-beams 1 are arranged on the top side of the bottom I-beams 7, a dust suction mechanism 5 is fixedly arranged between the upper parts of the plurality of side I-beams 1, a lifting brake mechanism 6 is slidingly arranged on both sides of the plurality of side I-beams 1, solid rubber wheels 8 are arranged on both sides of the bottom I-beams 7, a first construction platform 2, a second construction platform 3 and a third construction platform 4 are arranged on opposite sides of the plurality of side I-beams 1, a plurality of climbing ladders 9 are symmetrically arranged on the front top sides of the two bottom I-beams 7, the third construction platform 4 is provided with a hole, one of the climbing ladders 9 is arranged in the hole of the third construction platform 4, and the bottom side of the climbing ladder 9 is arranged on the top side of the second construction platform 3;

[0033] By adopting the above technical scheme, the bottom I-beams 7 on both sides support the multiple side I-beams 1 on the top side, and the two middle ones of the multiple side I-beams 1 on both sides support the fixed connecting blocks 602 in the lifting brake mechanism 6, and limit the lifting plate 601, and support the construction platform at the same time. Through the symmetrically arranged multiple climbing ladders 9, construction workers can climb to different construction platforms for construction. When the drilling and blasting trolley is moving, the staff needs to position the lifting brake mechanism 6. At this time, the transmission plate 507 in the dust suction mechanism 5 is pushed upward, so that the dust collection frame 508 is not easy to fall off from the dust suction mechanism 5. On the contrary, when the lifting brake mechanism 6 brakes the drilling and blasting trolley to make it unable to move, the dust collection frame 508 can be easily taken out therefrom, which is convenient for centralized treatment and replacement of dust.

[0034] See also Figure 1 , Figure 7 and Fig.10 As shown, the lifting brake mechanism 6 includes a lifting plate 601 and a fixed connection block 602, a forward and reverse motor 603 is fixedly arranged on the bottom side of the fixed connection block 602, the output end of the forward and reverse motor 603 is threadedly penetrated through the lifting plate 601, a placement frame 604 is fixedly arranged on the surface of the lifting plate 601, a brake block 608 is slidably arranged on the inner side of the placement frame 604, and a slotted plate 606 is fixedly arranged on the bottom side of the lifting plate 601, a support rod 616 is fixedly arranged between the inner sides of the slotted plate 606, and a brake spring 607 is arranged on the rod body of the support rod 616;

[0035] During use, the construction personnel control the forward and reverse motor 603. Due to the threaded engagement between the output end of the forward and reverse motor 603 and the lifting plate 601, the lifting plate 601 can rise and fall. When the lifting plate 601 descends, the slotted plate 606 on the bottom side of the lifting plate 601 will be brought down. During the continuous descent, the brake spring 607 continuously wraps the solid rubber wheel 8, so that the solid rubber wheel 8 cannot continue to rotate. After the brake block 608 falls from the placement frame 604, the construction personnel can place the brake block 608 on the rear side of the solid rubber wheel 8, and limit the solid rubber wheel 8 for the second time, so that the solid rubber wheel 8 is fixed more firmly, thereby ensuring the safety of the construction personnel on the construction platform of the drilling and blasting trolley.

[0036] Further, a fixing sleeve 605 is provided through the bottom side of the slotted plate 606, a sliding rod 615 is slidably provided inside the fixing sleeve 605, an L-shaped connecting plate 613 is fixedly provided on the top side of the sliding rod 615, a connecting drawstring 614 is fixedly provided on the bottom side of the L-shaped connecting plate 613, sliding grooves 619 are provided on both sides of the front side of the placement frame 604, a slotted slide plate 610 is slidably provided inside the sliding grooves 619, a connecting bent rod 618 is rotatably provided inside the front end of the slotted slide plate 610, and a connecting sleeve 617 is fixedly provided on the bottom side of the connecting drawstring 614;

[0037] By adopting the above embodiment, when the brake spring piece 607 is located on one side of the solid rubber wheel 8 and opens outward, the sliding rod 615 is pushed upward. When the sliding rod 615 moves upward on the inner side of the fixed sleeve 605, the connecting strap 614 on the bottom side of the other side is pulled upward by the L-shaped connecting plate 613 fixed on the top side of the sliding rod 615, so that the connecting strap 614 moves with the sliding rod 615. At the same time, the connecting bent rod 618 extending from the rear side of the slotted slide plate 610 is stuck in the connecting sleeve 617, and is moved upward by the connecting sleeve 617 on the bottom side of the connecting strap 614. The slotted slide plate 610 can move with the connecting strap 614. After the slotted slide plate 610 is pulled out, the brake block 608 set in the placement frame 604 falls off, and the staff places the brake block 608 in a suitable position to fix the drilling and blasting trolley, so as to facilitate secondary reinforcement and stability of the drilling and blasting trolley to ensure the personal safety of construction personnel on the construction platform of the drilling and blasting trolley.

[0038] Further, the connecting bent rod 618 is rotatably sleeved on the inner side of the connecting sleeve 617, and the sliding grooves 619 provided on the lower sides of the front and rear sides of the placement frame 604 are respectively provided with a first limiting column 611 and a second limiting column 612, the length of the first limiting column 611 is greater than the second limiting column 612, the rear side of the slotted slide plate 610 is forked, and the first limiting column 611 and the second limiting column 612 are arranged on the inner side of the fork of the slotted slide plate 610, and the third sliding groove 609 is provided on the upper front side of the placement frame 604, and the connecting drawstring 614 slides inside the third sliding groove 609;

[0039] When in use, when the connecting sleeve 617 is pulled by the connecting strap 614, the connecting bent rod 618 rotates inside the connecting sleeve 617, and then the connecting strap 614 pulls the slotted slide 610 out of the sliding groove 619 through the connecting sleeve 617, so that the slotted slide 610 no longer limits the brake block 608 placed inside the placement frame 604. At this time, the brake block 608 falls from the placement frame 604 so that the construction personnel can place it on one side of the solid rubber wheel 8 under the drilling and blasting trolley, and cooperate with the brake spring piece 607 to double fix the solid rubber wheel 8 to make it more stable. The first limiting column 611 and the second limiting column 612 pass through the inner sides of the two slotted slides 610 to limit the position of the slotted slide 610 to avoid the position of the slotted slide 610 from being tilted so that the brake block 608 cannot be limited. The third slide groove 609 not only facilitates the passage of the connecting strap 614, but also prevents the connecting strap 614 and the brake block 608 from contacting and entanglement.

[0040] Furthermore, the dust collection mechanism 5 includes a shell 501, two dust collection frames 508 are slidably arranged inside the shell 501, a fan 502 is fixedly arranged on the top side of the shell 501, and a dust suction port 503 is fixedly arranged on the bottom side of the shell 501, the two dust collection frames 508 are provided with collection ports on the top and bottom sides, a second slide 509 is fixedly arranged on the rear side of the dust collection frame 508, a first slide 504 is fixedly arranged on the upper front side of the inner wall of the shell 501, and fixed grooves 509 are fixedly arranged on both sides of the inner side of the first slide 504. Plate 512, an opening 506 is provided on the top side of the first slide groove 504, a spring 513 is fixedly provided on the inner side of the fixed plate 512, a sliding plate 514 is fixedly provided on one side of the spring 513, one side of the sliding plate 514 is provided as an inclined plate, a limit block 505 is fixedly provided on the lower front side of the inner wall of the housing 501, a transmission plate 507 is slidably provided on the inner side of the limit block 505, an oblique top plate 511 is fixedly provided on both sides of the transmission plate 507, and curved connecting blocks 510 are fixedly provided on both sides of the bottom side of the transmission plate 507;

[0041] Through the above technical scheme, the dust collecting frame 508 is through the holes opened on the top and bottom, and the wind force transmitted by the fan 502 passes through the holes of the dust collecting frame 508, and the wind force penetrates into the dust suction port 503 to the working position of the drilling and blasting trolley, and collects the dust generated by the blasting work to prevent the dust from causing damage to the bodies of the construction workers. At the same time, after the lifting plate 601 in the brake lifting mechanism rises, the drilling and blasting trolley can move quickly. At this time, the curved connecting block 510 connected to the top side of the lifting plate 601 is lifted, and the transmission plate 507 clamped by the two curved connecting blocks 510 moves upward. In the process of the transmission plate 507 rising, the sliding plate 514 sliding on the inner side of the first slide groove 504 is pushed to both sides through the angled top plates 511 above both sides of the transmission plate 507, so that the sliding plate 514 The dust collecting frame 508 is inserted into the groove on the inner side of the second slide groove 509 of the dust collecting frame 508, and the dust collecting frame 508 is clamped through the damping therebetween, so that the dust collecting frame 508 is not easy to be removed, thereby ensuring the stability of the dust collecting frame 508 on the inner side of the shell 501. Conversely, after the lifting plate 601 descends, the transmission plate 507 will also descend, so that the angled top plate 511 will descend accordingly. At this time, the fixed plates 512 arranged on both sides of the first slide groove 504 push the sliding plate 514 inwardly through the spring 513 in the fixed plate 512, so that the sliding plate 514 is reset and falls off from the second slide groove 509 of the dust collecting frame 508. At this time, the dust collecting frame 508 can be taken out from the inside, and the dust in the dust collecting frame 508 can be cleaned, thereby improving the dust collection effect of the dust collection mechanism 5.

[0042] By adopting the above structure, when the drilling and blasting trolley needs to be moved, the staff raises the position of the lifting plate 601 by the forward and reverse motor 603 in the lifting brake mechanism 6. At this time, the drilling and blasting trolley can be quickly moved through the solid rubber wheel 8 by manpower and the motor, making the working process of the drilling and blasting trolley more flexible. When the drilling and blasting trolley is working, the position of the lifting plate 601 is lowered by the forward and reverse motor 603. During the continuous descending process, the brake spring piece 607 in the slotted plate 606 contacts with the solid rubber wheel 8, so that the solid rubber wheel 8 cannot rotate. When the lifting plate 601 continues to descend, the contact area between the brake spring piece 607 and the solid rubber wheel 8 gradually increases. To improve the fixing effect of the solid rubber wheel 8, the side of the brake spring piece 607 that is not in contact with the solid rubber wheel 8 contacts the sliding rod 615, and the sliding rod 615 is pushed upward, and then the sliding rod 615 moves upward with the L-shaped connecting plate 613 and the connecting strap 614, and pulls the connecting sleeve 617 on the lower side of the connecting strap 614, and at the same time, the connecting curved rod 618 on the inner side of the connecting sleeve 617 and the slotted slide plate 610 on one side of the connecting curved rod 618 are pulled out from the sliding groove 619, at this time, the brake block 608 on the inner side of the placement frame 604 will fall off, making the solid rubber wheel 8 unable to rotate, and the solid rubber wheel 8 is fixed with the brake spring piece 607, so as to ensure that the drilling and blasting trolley is displaced during work;

[0043] At the same time, when the lifting plate 601 descends, the transmission plate 507 is brought down through two curved connecting blocks 510 arranged on the top side of the lifting plate 601. When descending, the angled top plates 511 on both sides of the transmission plate 507 are brought down, and then the sliding plate 514 is pulled back to its original position by the spring 513. When the sliding plate 514 is reset, it will fall off from the second sliding groove 509, so that the second sliding groove 509 on the rear side of the dust collecting frame 508 is no longer restricted by the sliding plate 514, making it easier for the staff to take out the dust collecting frame 508 from the inside of the outer shell 501 and clean the inside of the dust collecting frame 508.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
