Description

Technical Field

[0001] This application relates to the field of hydropower engineering construction technology, and in particular to a sealing and protection device for slag chute wells. Background Technology

[0002] In the field of shaft construction, the reverse shaft drilling method is a commonly used technique. This method typically involves first constructing a central chute as a subsequent muck removal channel, and then excavating the entire cross-section of the shaft from top to bottom.

[0003] Traditional shaft enlargement operations are complex, involving the collaboration of multiple professional trades: construction workers must descend to the working face to work with machinery to perform drilling, charging, blasting, muck removal, and support operations. During this process, personnel ventilation and the removal of blasting debris are highly dependent on the central chute.

[0004] However, this conventional excavation method has significant safety risks: since the chute is the only open passage through the entire depth of the shaft and has a relatively large diameter, there is a major safety hazard of workers and small equipment accidentally falling into the chute; in addition, the working face after blasting is uneven, which makes it difficult to control the distance between the landing point or placement position of personnel and materials and the well opening when they are lowered to the working face by hoisting equipment, which can easily lead to instability, slippage and other accidents, resulting in high operational safety risks. Utility Model Content

[0033] Traditional shaft enlargement operations are complex, involving the collaboration of multiple professional trades: construction workers must descend to the working face to work with machinery to perform drilling, charging, blasting, muck removal, and support operations. During this process, personnel ventilation and the removal of blasting debris are highly dependent on the central chute.

[0034] However, this conventional excavation method has significant safety risks: since the chute is the only open passage through the entire depth of the shaft and has a relatively large diameter, there is a major safety hazard of workers and small equipment accidentally falling into the chute; in addition, the working face after blasting is uneven, which makes it difficult to control the distance between the landing point or placement position of personnel and materials and the well opening when they are lowered to the working face by hoisting equipment, which can easily lead to instability, slippage and other accidents, resulting in high operational safety risks.

[0035] To address the aforementioned issues, this application provides a slag chute sealing and protection device that effectively prevents the risk of personnel and small equipment falling while ensuring ventilation of the slag chute and guaranteeing construction safety.

[0036] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0040] See Figure 1-3 A sealing and protection device for slag chute wells, comprising:

[0041] The sealing frame 1 is an octagonal frame assembled from I-beams.

[0042] A sealing steel plate 2 is installed at the top center of the sealing frame 1, and steel mesh 3 is installed at other positions on the top of the sealing frame 1.

[0043] Specifically: the steel mesh plate 3 is composed of threaded steel bars directly welded to the sealing frame 1 to ensure safety when stepping on it.

[0044] In this embodiment, 40b and 36b I-beams are used to weld an octagonal frame. The I-beams serve as the basic structure of the device, which can be stably placed on the slag chute, ensuring overall stability. A 2cm thick checkered steel plate is used as a sealing steel plate 2 to cover the slag chute opening and seal it. Furthermore, by setting up a steel mesh plate 3, the risk of personnel and small equipment falling can be effectively avoided while ensuring the ventilation effect of the slag chute and ensuring the safety of personnel stepping on it.

[0045] Specifically: The bottom of the sealing frame 1 is equipped with a hanging mesh 8 through holes, and the hanging mesh 8 is installed and fixed by drilling holes in the I-beam at the bottom of the sealing frame 1.

[0046] In this embodiment, by setting up the hanging net 8, the hanging net 8 can effectively intercept debris, reduce the risk of debris falling, and ensure construction safety.

[0047] The size of the sealing steel plate 2 is larger than the diameter of the corresponding slag chute. A limit plate 4 is installed on the sealing steel plate 2 to limit the movement of the personnel cage and ensure the safety of construction operations.

[0048] Specifically: The limiting plate 4 uses five 10mm thick steel plates arranged in parallel at intervals, and then uses two steel plates with ribs welded together to make four braking plates, which serve as the limiting device after the manned cage is lowered into the well.

[0049] In this embodiment, by setting a limiting plate 4, with steel plates spaced apart in the middle of the limiting plate 4, the manned cage can be precisely limited to avoid slippage and ensure construction safety.

[0050] A limiting post 5 is installed at the bottom of the sealing frame 1 to limit the sealing frame 1.

[0051] In this embodiment, the limiting post 5 is made of 36b I-beams and is symmetrically welded to the central frame of the chute along the center of the chute. It extends deep into the chute and has a length of not less than 1300mm, which limits the horizontal displacement of the entire device and prevents the device from deviating too far from the center of the chute, thus preventing the chute from being sealed in a loose manner.

[0052] Four lifting lugs 6 are installed on the top of the sealing frame 1.

[0053] In this embodiment, four lifting lugs 6 are symmetrically arranged around the manhole cover and reinforced by welding to facilitate transportation by the lifting device.

[0054] Specifically: the side wall of the sealing frame 1 is provided with a crash plate 7.

[0055] In this embodiment, the anti-collision plate 7 is made of rubber, which can effectively reduce collision damage to the device.

[0056] The technical solution provided in this application has the following beneficial effects:

[0057] This application utilizes I-beams as the foundation structure of the device, ensuring stable placement on the slag chute and guaranteeing overall stability. A sealing steel plate 2 covers the slag chute opening, effectively sealing it. Furthermore, a steel mesh plate 3 effectively prevents the risk of personnel and small equipment falling while maintaining ventilation in the slag chute, ensuring personnel safety. Simultaneously, a limiting plate 4, with steel plates spaced apart, precisely limits the position of the personnel cage, preventing slippage and ensuring construction safety.

[0058] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
