Description

Technical Field

[0001] The invention relates to the technical field of blasting, and in particular to a foldable and delivered civilian blasting device. Background Art

[0002] Wall blasting is an engineering technology that uses explosives or other blasting devices to destroy the entire wall structure or the specified location. It is mainly used for building demolition, underground projects (subways or tunnels), dam construction or reconstruction, etc. It is particularly suitable for construction sites with inconvenient transportation and no large-scale equipment.

[0003] Wall blasting faces a complex working environment, and the safety of personnel and environmental impact during the blasting process must be fully considered. Blasting work itself has a high safety risk, and improper operation may cause casualties or damage to the surrounding environment. Existing wall blasting mostly uses a fixed blasting structure, which is installed at a designated location on the wall by relevant personnel, and then remotely detonated after the personnel evacuate. This blasting method is inefficient. Since the size of the blasting structure is often fixed, there are many difficulties in the transportation and installation process, and it poses a threat to personnel safety.

[0004] Currently, the main defects of wall blasting equipment are inconvenient movement, large size and difficult installation. Summary of the invention

[0005] In view of this, the present invention provides a foldable and delivered civilian blasting device.

When the wall blasting structure 4 is in a folded state, as shown in FIG. Figure 1 and Figure 6As shown, 12 charge connecting rods 41 are in a horizontal state, 1 active slider 42 and 4 two-connected driven sliders 43 are located at the same end of the 12 charge connecting rods 41, each two-connected driven slider 43 is hinged to the same end of two charge connecting rods 41, and the active slider 42 is located at the center of the four two-connected driven sliders 43; four three-connected driven sliders 44 are located at the other end of the 12 charge connecting rods 41, and each three-connected driven slider 44 is hinged to three charge connecting rods 41; the charge connecting rod 41 at the bottom of the wall blasting structure 4 is supported on the support At the top of the plate 25, a fixed base 38 is fixedly installed in the groove of the active slider 42, the support rod 35 passes through the central hole of the active slider 42, and an electromagnet 36 is fixedly installed at the end of the support rod 35.

[0064] Since the deployment of the wall blasting structure 4 requires a certain space, the primary delivery structure 2 is required to transport the secondary delivery structure 3 and the wall blasting structure 4 as a whole to the front end of the unmanned platform 1 so that the wall blasting structure 4 can be deployed. The secondary delivery structure 3 and the wall blasting structure 4 can be delivered to a suitable position as a whole through the pen-type push rod 22. A plurality of first balls 24 are installed on the bottom surface of the delivery plate 23 in the primary delivery structure 2. The sliding friction generated by the relative movement between the delivery plate 23 and the roof plate 21 is converted into rolling friction through the first balls 24, so that the primary delivery structure 2 can deliver the secondary delivery structure 3 and the wall blasting structure 4 to the front end of the unmanned platform 1, thereby realizing the deployment of the wall blasting structure 4.

[0065] Figure 8 A flow chart of the wall blasting task performed in this embodiment is given. The unmanned platform 1 carries the two-stage delivery structure and the blasting structure for transportation; when arriving at the designated delivery position, the pen-type push rod 22 of the primary delivery structure 2 extends through the delivery plate 23 to drive the secondary delivery structure 3 and the blasting structure to be transported as a whole to the front end of the unmanned platform 1 so that the blasting structure can be deployed. At the same time, it is necessary to ensure that the fixed base 38 in the secondary delivery structure 3 is completely in contact with the wall surface; then, the blasting structure is gradually opened by the secondary delivery platform until it is completely in contact with the wall surface; finally, the connection between the support rod 35 and the fixed base 38 is disconnected by the electromagnet 36, and the secondary delivery structure 3 is recovered by the primary delivery structure 2. After the unmanned platform 1 returns, remote detonation is implemented to complete the blasting task.
