Description

Technical Field

[0001] This utility model relates to the field of red sandstone blasting technology, specifically, to a blasting device suitable for red sandstone. Background Technology

[0002] Red sandstone, as a typical sedimentary rock, possesses certain unique characteristics in its composition and structure. The blasting properties of red sandstone are typically influenced by its mineral composition, hardness, porosity, bedding structure, and stress state. Red sandstone is mainly composed of quartz, feldspar, and clay minerals, generally exhibiting high porosity and low density. Its compressive and tensile strengths are generally low. However, due to its bedding structure and heterogeneity, the rock fragmentation effect after blasting may be uneven; some areas may be well-fragmented, while others may retain larger rock fragments. Therefore, the design of blasting devices for red sandstone requires special consideration of how to control the size of the blasted rock fragments, improve the uniformity of fragmentation, and ensure the safety and efficiency of the mining operation.

[0003] According to a disclosed simplified blasting device (Announcement No.: CN206177153U), it includes a blasting device body and a protective shell covering the blasting detonator body. The upper part of the blasting device body is provided with a cylindrical sealed protruding plug, and the interior is provided with several partition layers. The partition layers divide the blasting device body into several small chambers. The partition layer is composed of a sandwich layer and upper and lower partitions. Each small chamber is provided with explosives, a detonator, and a lead wire matching the detonator.

[0004] However, after blasting the red sandstone, the above design still contains large rocks, which is not conducive to subsequent work and needs to be improved. Utility Model Content

[0005] This invention proposes a blasting device suitable for red sandstone.

[0006] The technical solution of this utility model is as follows: A blasting device suitable for red sandstone includes a blasting tube, a fixed plate is provided on the inner wall of the blasting tube, a remote-controlled blasting component is provided on the circumferential surface of the blasting tube, a large-area blasting mechanism is provided at the bottom of the blasting tube, the large-area blasting mechanism includes a fixed block, a hollow block is fixedly connected to the side of the fixed block, a torsion spring rod is rotatably connected to the inner side wall of the hollow block, a sleeve is fixedly connected to the circumferential surface of the torsion spring rod, a connecting plate is fixedly connected to the circumferential surface of the sleeve, a placement box is fixedly connected to the side of the connecting plate, a rectangular block is fixedly connected to the circumferential surface of the blasting tube, a pull rope passes through the bottom of the rectangular block, a pull ring is fixedly connected to the circumferential surface of the pull rope, a rectangular plate is fixedly connected to the circumferential surface of the blasting tube, a vacuum block is fixedly connected to the side of the rectangular plate, a sliding block is slidably connected to the bottom of the inner wall of the vacuum block, and a limit block is fixedly connected to the top of the sliding block.

[0007] A handle is fixedly connected to the top of the limiting block, and a spring is fixedly connected to the front side of the sliding block. The end of the spring away from the sliding block is fixedly connected to the inner wall of the vacuum block. The design of the spring is conducive to driving the sliding block to limit the pull ring.

[0008] The side section of the vacuum block is concave, and the pull rope passes through the top of the rectangular block and is slidably connected to the rectangular block. The design of the pull rope facilitates operation by the staff.

[0009] One end of the pull rope is fixedly connected to the circumference of the pull ring, and the end of the pull rope away from the pull ring is fixedly connected to the side of the connecting plate. This design is beneficial for driving the connecting plate to move.

[0010] The top of the fixed plate is equipped with a detachable lighting mechanism, which includes a light lamp. The light lamp is located on the top of the fixed plate. This design facilitates blasting operations by workers at night.

[0011] A round shaft is fixedly connected to the top of the fixed plate, and a threaded sleeve is fixedly connected to the top of the round shaft. A bolt is threadedly connected to the inner wall of the threaded sleeve. The above design facilitates the disassembly of the lighting lamp.

[0012] The bolts are fixed to the bottom of the light fixture, and this design facilitates disassembly by workers.

[0013] The limiting block contacts the inner wall of the pull ring, and the side cross-section of the vacuum block is set to be concave. The above design makes it easier for the operator to drive the torsion spring rod to rotate.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. This utility model utilizes the rotational force of a torsion spring rod to drive the components such as a fixed block, sleeve, connecting plate, placement box, rectangular plate, pull rope, rectangular plate, vacuum block, sliding block, and limiting block to work together. This enables the handle fixed to the top of the limiting block to be pulled, thereby pushing the limiting block and causing the sliding block to slide. When the sliding block slides, the spring fixed to the front side is kept in a taut state. When the sliding block slides, it causes the limiting block to move and no longer contact the inner wall of the pull ring, thus reducing the probability of large rocks when blasting red sandstone.

[0016] 2. This utility model uses the rotational force of the bolt to drive the lighting lamp, threaded sleeve, round shaft and other components to work together to turn on the lighting lamp fixed on the top of the bolt for illumination. When blasting is carried out during the day, the workers turn the lighting lamp, which drives the bolt threaded to the inner wall of the threaded sleeve to rotate, so that blasting can be carried out at night.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-5 As shown, this embodiment proposes a blasting device suitable for red sandstone, including a blasting tube 1, a fixing plate 2 provided on the inner wall of the blasting tube 1, a remote-controlled blasting component 5 provided on the circumferential surface of the blasting tube 1, and a large-area blasting mechanism 3 provided at the bottom of the blasting tube 1. The large-area blasting mechanism 3 includes a fixing block 31, a hollow block 315 fixedly connected to the side of the fixing block 31, a torsion spring rod 32 rotatably connected to the inner side wall of the hollow block 315, and a sleeve 33 fixedly connected to the circumferential surface of the torsion spring rod 32. A connecting plate 34 is fixedly connected to the circumference of the blasting tube 1. A placement box 35 is fixedly connected to the side of the connecting plate 34. A rectangular block 36 is fixedly connected to the circumference of the blasting tube 1. A pull rope 37 passes through the bottom of the rectangular block 36. A pull ring 313 is fixedly connected to the circumference of the pull rope 37. A rectangular plate 38 is fixedly connected to the circumference of the blasting tube 1. A vacuum block 39 is fixedly connected to the side of the rectangular plate 38. A sliding block 310 is slidably connected to the bottom of the inner wall of the vacuum block 39. A limit block 311 is fixedly connected to the top of the sliding block 310.

[0028] A handle 312 is fixedly connected to the top of the limiting block 311, and a spring 314 is fixedly connected to the front side of the sliding block 310. The end of the spring 314 away from the sliding block 310 is fixedly connected to the inner wall of the vacuum block 39. The design of the spring 314 is conducive to driving the sliding block 310 to limit the pull ring 313.

[0029] The side section of the vacuum block 39 is concave, and the pull rope 37 passes through the top of the rectangular block 36 and is slidably connected to the rectangular block 36. The design of the pull rope 37 facilitates operation by the staff.

[0030] One end of the pull rope 37 is fixedly connected to the circumferential surface of the pull ring 313, and the end of the pull rope 37 away from the pull ring 313 is fixedly connected to the side of the connecting plate 34. The above design is conducive to driving the connecting plate 34 to move.

[0031] In this embodiment, when blasting is required, the worker first installs the explosive inside the placement box 35, and then pulls the handle 312 fixed to the top of the limiting block 311, thereby pushing the limiting block 311 and causing the sliding block 310 to slide. When the sliding block 310 slides, the spring 314 fixed to the front side is in a taut state. When the sliding block 310 slides, it causes the limiting block 311 to move and no longer contact the inner wall of the pull ring 313. When the limiting block 311 no longer contacts the pull ring 313, the rotating torsion spring rod 32 is no longer blocked by the pull rope 37, thereby causing the connecting plate 34 to move downward in an arc, and at the same time causing the placement box 35 fixed to the side to move downward in an arc. When the torsion spring rod 32 stops rotating, the placement box 35 stops moving. At this time, the worker places the blasting device to blast, expanding the blasting range and reducing the probability of large rocks.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a second embodiment, in which a detachable lighting mechanism 4 is provided on the top of the fixed plate 2. The detachable lighting mechanism 4 includes a lighting lamp 41, which is provided on the top of the fixed plate 2. The above design is conducive to facilitating workers to carry out blasting operations at night.

[0034] A round shaft 44 is fixedly connected to the top of the fixed plate 2, and a threaded sleeve 42 is fixedly connected to the top of the round shaft 44. A bolt 43 is threadedly connected to the inner wall of the threaded sleeve 42. The above design facilitates the disassembly of the lighting lamp 41.

[0035] Bolt 43 is fixedly connected to the bottom of the lighting lamp 41. The above design facilitates disassembly operations by workers.

[0036] The limiting block 311 contacts the inner wall of the pull ring 313, and the side section of the vacuum block 39 is set to be concave. The above design makes it easier for the staff to drive the torsion spring rod 32 to rotate.

[0037] In this embodiment, when the blasting is carried out at night, the staff turns on the light 41 fixed to the top of the bolt 43 for illumination. When the blasting is carried out during the day, the staff rotates the light 41, thereby causing the bolt 43, which is threaded to the inner wall of the threaded sleeve 42, to rotate. After rotating a certain number of times, the bolt 43 disengages from the inner wall of the threaded sleeve 42, and the disassembly is completed.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
