Description

Technical Field

[0001] This invention relates to the field of blasting technology, and in particular to an intelligent explosive delivery device for blasting. Background Technology

[0002] During blasting excavation, explosives need to be manually loaded into the blasting hole, which is then sealed. Due to the depth of the blasting hole, auxiliary tools are needed to push the explosives to the corresponding depth within the hole to ensure the blasting effect. Currently, explosives are commonly pushed using a ram along the inner wall of the blasting hole to the corresponding position. However, because the ram directly pushes the explosives, it is easy to damage them, affecting the blasting effect. Furthermore, the explosives are in direct contact with the inner wall of the blasting hole during pushing, making them prone to damage and breakage, thus affecting the blasting effect.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] A smart explosive delivery device includes an explosive charge placement housing 1, a horizontally connected fixing rod 2 at the middle of one side of the explosive charge placement housing 1, and symmetrically opened sliding grooves 10 on both sides of the bottom of the explosive charge placement housing 1. An explosive charge placement plate 11 is slidably installed in the sliding grooves 10, and an explosive charge dispensing cavity 9 is opened on the side of the explosive charge placement housing 1 away from the fixing rod 2. A limiting groove is opened in the explosive charge placement housing 1 on the side of the explosive charge dispensing cavity 9 and at the corresponding explosive charge placement plate 11.

[0026] Meanwhile, a limiting fixing block 6 is installed on the side of the medicine pack housing 1 away from the fixing rod 2 and at the corresponding slide groove 10. The limiting fixing block 6 has a locking groove 61 on the side near the slide groove 10. The top and bottom of the limiting fixing block 6 located in the corresponding locking groove 61 and the side near the slide groove 10 are all provided with cavities. A locking mechanism 7 is provided in the cavity.

[0027] Meanwhile, the locking mechanism 7 includes a limiting locking plate 71, a connecting slide plate 73, and an electric telescopic rod 75. The limiting locking plate 71 is rotatably installed in the cavity of the limiting fixing block 6 near the locking groove 61 via a rotating shaft. Multiple springs 72 are installed at equal intervals on the bottom of the side of the limiting locking plate 71 away from the slide groove, and the other end of the springs 72 is connected to the bottom of the cavity of the limiting fixing block 6.

[0028] Furthermore, a locking groove is provided at the bottom of the cavity of the limiting and fixing block 6 and on one side of the corresponding spring 72. A connecting slide plate 73 is slidably installed in the locking groove. A through groove 731 is provided in the middle of the connecting slide plate 73, and a limiting plate 74 is slidably installed in the through groove 731.

[0029] Furthermore, a sliding cavity is provided in the limiting and fixing block 6 at the corresponding limiting plate 74, and placement cavities are provided on both sides below the corresponding sliding cavity in the limiting and fixing block 6. An electric telescopic rod 75 is provided in the placement cavity, and the output end of the electric telescopic rod 75 passes through the placement cavity and connects to the limiting plate 74.

[0030] Meanwhile, a limiting groove 711 is provided at the bottom of the limiting plate 71 and between the corresponding pivot and spring 72, and a sliding block is slidably installed in the limiting groove 711, with the bottom of the sliding block being rotatably connected to the connecting slide plate 73.

[0031] Furthermore, a through hole is provided in the limiting and fixing block 6 between the corresponding locking groove 61 and the cavity, and on the side of the limiting plate 71 near the spring 72. The end of the limiting plate 71 near the spring 72 rotates under the action of the spring 72 and the rotating shaft and passes through the through hole.

[0032] Furthermore, a handle 4 is installed on the side of the fixing rod 2 away from the medicine pack placement housing 1, and scale lines 8 are provided on both sides of the fixing rod 2 and the medicine pack placement housing 1. The starting end of the scale line 8 is "0", and the starting end of the scale line 8 is the side close to the medicine pack placement housing 1 and the medicine dispensing hole. A control switch group is provided on the top side of the handle 4, and the control switch group is connected to control the electric telescopic rod 75 through an electrical signal.

[0033] Furthermore, the medicine pack placement plate 11 is horizontally installed with an extension protrusion 12 at the corresponding locking groove 61 of the limiting fixing block 6. The extension protrusion 12 is T-shaped and includes a connecting part and a locking part. The height of the locking part is the same as the height of the locking groove 61, and the height of the connecting part is half the height of the locking part.

[0034] A wear-resistant pull rope 5 is connected to the middle of the side of the medicine pack placement plate 11 near the fixing rod 2, and the other end of the wear-resistant pull rope 5 passes through the fixing rod 2 and the handle part 4 in sequence and is connected to the limit pull ring 51. A limit groove is opened in the middle of the side of the medicine pack placement plate 11 near the medicine dispensing cavity, and a pull handle is horizontally installed in the middle of the limit groove.

[0035] Furthermore, a limit ring 3 is slidably installed on the outer wall of its fixing rod 2, and the limit ring 3 is made of transparent material.

[0036] In this invention, when it is necessary to place the medicine pack to be pushed, the medicine pack placement plate 11 is slid downwards into the medicine cavity and the limiting fixing block 6 by holding the handle, so that the extension protrusion 12 of the medicine pack placement plate 11 is engaged in the engaging groove 61 of the limiting fixing block 6. When the extension protrusion 12 of the medicine pack placement plate 11 moves into the engaging groove 61 of the limiting fixing block 6, the extension protrusion 12 abuts against its limiting plate 71, and the limiting plate 71 is under the action of the rotating shaft and the spring. The extension protrusion 12 is rotated and rotated into the cavity of the corresponding limiting fixing block 6. When the locking part of the extension protrusion 12 is located in the corresponding locking groove 61, the medicine pack placement plate 11 is installed. At the same time, when the locking part of the extension protrusion 12 is located in the corresponding locking groove 61, the end of the limiting plate 71 near the spring rotates under the action of the spring and the rotating shaft and passes through its through hole, thereby limiting and locking the locking part of the extension protrusion 12, and then limiting and locking the medicine pack placement plate 11.

[0037] Next, the explosive charge placement housing 1 moves the corresponding explosive charge into the blast hole and aligns its limiting ring 3 with the outer wall of the corresponding blast hole. Then, the explosive charge is pushed into the blast hole under the action of its fixing rod 2. By observing the scale line 8 and the limiting ring 3, the distance that the explosive charge is pushed into the blast hole can be known, so as to quickly know that the explosive charge has been delivered to the bottom of the blast hole.

[0038] When the explosive charge placement housing 1 moves the corresponding explosive charge to the designated position, the electric telescopic rod 75 is closed by pressing the control switch. The electric telescopic rod 75 moves the corresponding limiting plate 74 to the side away from the locking groove 61 of the limiting fixing block 6, and drives the corresponding limiting plate 71 to rotate under the action of its rotating shaft, so that the limiting plate 71 is located in the cavity of the corresponding limiting fixing block 6. Then, by pulling its limiting pull ring 51, the corresponding wear-resistant pull rope 5 moves to the side away from the handle part 4, and at the same time, it moves the explosive charge placement plate 11 to the corresponding limiting groove. While the explosive charge placement plate 11 moves into the limiting groove, the explosive charge moves along its lowering cavity into its blasting hole and is located in the corresponding blasting hole.

[0039] During the process of pushing the explosive charge, the explosive charge placement plate 11 and the explosive charge placement housing 1 place the explosive charge to be pushed, ensuring the limit and stability of the explosive charge placement plate 11, and at the same time ensuring that the explosive charge is protected during the pushing process, avoiding the risk of explosion caused by friction between the explosive charge and the inner wall of the blast hole during the pushing process.

[0040] Meanwhile, under normal circumstances, its electric telescopic rod 75 is in the normally open state.

[0041] In this invention, the medicine pack placement plate 11 and the medicine pack placement housing 1 place the medicine pack to be pushed, and during the pushing process, the medicine pack placement plate 11 is limited and locked by the locking mechanism 7 to ensure the limitation and stability of the medicine pack placement plate 11, and at the same time, to ensure that the medicine pack is protected during the pushing process, so as to avoid the risk of explosion caused by friction between the medicine pack and the inner wall of the blast hole during the pushing process.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
