Description

Technical Field

[0001] This utility model relates to the field of construction technology, and in particular to a device for blocking construction orifices. Background Technology

[0002] Currently, static crushing is generally used in concrete building demolition, rock breaking, and stone quarrying. This method is safe and reliable, and does not produce the pollution caused by blasting. Its principle is to place an expanding agent inside the blast hole, and use the expanding force generated by the agent to slowly act on the hole wall, causing the medium to crack.

[0003] When the expanding agent expands, the blasting holes created during construction need to be plugged to prevent the expanding agent from spraying out. If blowout occurs, the hole needs to be re-drilled and refilled with expanding agent, reducing work efficiency, and the sprayed material can easily cause injury to workers. Current methods for sealing the construction holes in static crushing methods mostly use clay or sand, requiring manual compaction. This method is inefficient and has poor plugging effect, still carrying the risk of blowout. Utility Model Content

[0022] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0023] As attached Figure 1 As shown, this utility model provides a construction orifice plugging device, comprising:

[0024] Threaded rod 1;

[0025] Baffle 2 is located at the bottom of threaded rod 1 and is bolted to threaded rod 1;

[0026] The horn sleeve 3 has an opening facing downwards. The top of the horn sleeve 3 has a through hole, and the bottom abuts against the baffle 2. The horn sleeve 3 is fitted onto the threaded rod 1 through the through hole. The horn sleeve 3 and the threaded rod 1 are slidably connected. The bottom of the horn sleeve 3 is made of elastic material.

[0027] The first connecting rod 4 has one end rotatably connected to the top of the horn sleeve 3 and the other end rotatably connected to the bottom of the horn sleeve 3. Multiple first connecting rods 4 are evenly distributed along the circumference of the horn sleeve 3.

[0028] Screw sleeve 5 is located above the horn sleeve 3 and is threadedly connected to the threaded rod 1;

[0029] An elastic sealing ring is located on the outer side of the bottom of the speaker sleeve 3.

[0030] In actual use, the operator first places the device into the hole and rotates the screw sleeve 5 to move it downwards along the threaded rod 1. As the screw sleeve 5 moves, it contacts the top of the horn sleeve 3, causing the horn sleeve 3 to move downwards along the threaded rod 1. This downward movement of the horn sleeve 3 causes the first connecting rod 4, which rotates at both ends of the horn sleeve 3, to rotate outwards. This causes the bottom of the horn sleeve 3 to press against the baffle 2 and move outwards a certain distance on the baffle 2, bringing the elastic sealing ring into contact with the inner wall of the blast hole, thus fixing the device inside the blast hole. At this point, the baffle 2, the horn sleeve 3, and the elastic sealing ring together seal the blast opening.

[0031] Specifically, the bottom of the horn sleeve 3 extends outward a certain distance and the extended part has a certain thickness, so that the bottom of the horn sleeve 3 can deform to a certain extent under the action of the first connecting rod 4, ensuring the tightness between the horn sleeve 3 and the baffle 2 and the inner wall of the blast hole.

[0032] In this embodiment, a retractable ring is provided on the outer side of the bottom of the horn sleeve 3, and an elastic sealing ring is provided on the outer side of the retractable ring, thereby ensuring the tightness of the fit between the elastic sealing ring and the inner wall of the rupture hole.

[0033] In another embodiment, a side plate 6 is provided on the outer side of the bottom of the horn sleeve 3, an elastic sealing ring is provided on the outer side of the side plate 6, a horn cover 7 is provided below the baffle 2, the opening of the horn cover 7 faces downward, a second connecting rod 8 is provided between the horn cover 7 and the side plate 6, the first end of the second connecting rod 8 is rotatably connected to the bottom of the side plate 6, the second end is rotatably connected to the horn cover 7, and multiple second connecting rods 8 are evenly distributed along the circumference of the side plate 6, and the side plate 6 is made of elastic material.

[0034] As the expanding agent expands within the blast hole, it drives the horn cover 7 to move upwards, which in turn drives the second connecting rod 8 to rotate outwards. This outward rotation of the second connecting rod 8 exerts a force on the side plate 6, causing it to move towards the inner wall of the blast hole. This further improves the fixation and sealing effect between the device and the blast hole, ensuring the device's effectiveness.

[0035] In another embodiment, a hanging plate 9 is provided on the side plate 6 for hanging the device on the opening. This facilitates the installation of the device and reduces the effect of gravity on the device.

[0036] In another embodiment, the screw sleeve 5 is provided with a handle 10 to facilitate operation by staff.

[0037] In another embodiment, a limiting plate 11 is provided on the threaded rod 1, and the limiting plate 11 is located between the baffle 2 and the horn sleeve 3. This limits the movement distance of the horn sleeve 3, preventing excessive force from the threaded rod on the horn sleeve 3 and thus avoiding damage to the device.

[0038] In another embodiment, a handle is provided at the top of the threaded rod 1. This facilitates carrying and operation by workers.

[0039] In another embodiment, a tension spring is provided between the horn sleeve 3 and the baffle 2. One end of the tension spring is connected to the top of the horn sleeve 3, and the other end is connected to the baffle 2. Multiple tension springs are evenly distributed along the circumference of the threaded rod 1. The tension spring provides a downward force to the horn sleeve 3, ensuring that the bottom of the horn sleeve 3 is in close contact with the baffle 2, thus ensuring the sealing of the device.

Anyone should know that structural changes made under the guidance of the present utility model are protected by the present utility model. All technical solutions that are the same as or similar to the present utility model are within the scope of protection of the present utility model.
