Description

Technical Field

[0001] The present application relates to the technical field of concrete spraying construction, and in particular to a cavern lining support spraying concrete construction device. Background Art

[0002] Concrete spraying is carried out in a timely manner according to the surrounding rock conditions exposed during excavation. When excavating Class II and Class III surrounding rocks, due to good geological conditions, the construction of spraying concrete can be delayed by a distance from the excavation face. For Class IV and surrounding rock sections with poor geological conditions, in order to ensure the stability of the cavern surrounding rock and construction safety, the "short step method" is used for excavation. After the upper part is excavated, anchor spraying support is carried out in time.

[0003] Sprayed concrete is mainly constructed using the wet spraying process of sprayed concrete equipment, with layered spraying and mesh sprayed concrete constructed according to the "spray-net-spray" procedure.

[0004] The spraying concrete operation is carried out in sections and pieces, first on the side walls and then on the top arch. The side walls are sprayed in layers of 4 to 6 cm, and the top arch is sprayed in layers of 3 to 5 cm thick. The latter layer is carried out after the previous layer of concrete has finally set. If spraying is done more than 1 hour later, clean the sprayed surface with Feng Shui first.

[0005] In the prior art, the shotcrete construction device for cavern lining support includes a mobile mechanism, a storage box for storing concrete mixing materials arranged on the mobile mechanism, and a spraying pipe connected to the storage box. Although the device can be moved in the cavern through the mobile mechanism to spray concrete, the ground in the cavern is often uneven (including the obstruction of movable stones). Therefore, the following technical problems exist:

[0006] 1. During the movement of the construction equipment, due to the heavy total weight of concrete and equipment, it is difficult to move or easily tip over when passing through uneven locations;

[0007] 2. During the spraying process, the device cannot be easily rotated, which causes the spray pipe to be restricted by position, resulting in a short spraying distance. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In response to the above problems, an embodiment of the present application provides a cavern lining support shotcrete construction device, which can avoid the problem of being difficult to move or prone to tipping over during movement.

[0034] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0035] See also Figure 1 The cavern lining support shotcrete construction device includes a moving mechanism 1, a storage box 2, and a spraying pipe 3; the moving mechanism 1 is provided with a storage box 2 for storing concrete mixing materials, and the storage box 2 is installed with a spraying pipe 3. The moving mechanism 1 includes an outer moving frame 4, a mounting plate 5, a longitudinal telescopic mechanism A6, and a rotating mechanism 9. The mounting plate 5 is slidably installed on the outer moving frame 4, the storage box 2 is arranged on the mounting plate 5, the bottom of the mounting plate 5 is installed with a rotating mechanism 9, and the bottom of the rotating mechanism 9 is installed with a longitudinal telescopic mechanism A6.

[0036] During operation, when it is necessary to construct shotcrete for supporting the cavern lining, when the ground is flat, the outer movable frame 4 is pushed to drive the mounting plate 5 and the storage box 2 and the injection pipe 3 on the mounting plate 5 to move to the designated position. After the movement, the shotcrete construction for supporting the cavern lining can be carried out; when the ground is uneven, the mounting plate 5, the outer movable frame 4 and the storage box 2 are lifted off the ground by extending the longitudinal telescopic mechanism A6 (which can be a hydraulic telescopic mechanism or a manual fixed telescopic structure), and the outer movable frame 4 on the mounting plate 5 is slid. After the movement, the longitudinal telescopic mechanism A6 contracts to make the outer movable frame 4 contact with the ground, and separates the longitudinal telescopic mechanism A6 from the ground. After separation, the mounting plate 5 on the outer movable frame 4 and the storage box 2 thereon are slid to cross the uneven place (especially the position with a large depth of unevenness), thereby avoiding the problem of being difficult to move or prone to tipping during the movement. The purpose of setting the rotating mechanism 9 is to facilitate the rotation of the direction of the outer movable frame 4, the mounting plate 5 and the storage box 2, so as to facilitate movement in different directions.

[0037] In some embodiments, see Figure 2 The outer movable frame 4 includes two oppositely arranged inverted U-shaped frames 10, the inverted U-shaped frame 10 includes a cross bar 11, a vertical bar 12 arranged at both ends of the cross bar 11, a pulley 13 is arranged at the bottom end of the vertical bar 12, a T-shaped slide groove 14 is arranged on the opposite sides of the two cross bars 11, and a slide groove 16 is arranged on both sides of the T-shaped slide groove 14. A slider A15 matching with the T-shaped slide groove 14 is arranged on the mounting plate 5, and the mounting plate 5 is slidably installed on the cross bar 11 through the slider A15 matching with the T-shaped slide groove 14.

[0038] When working, the outer movable frame 4 is two inverted U-shaped frames 10, and a T-shaped slide 14 is arranged on the cross bar 11 thereon to match with the slider A15 arranged on the mounting plate 5. The structure is simple and is conducive to matching with the mounting plate. In practice, when the ground is uneven, the mounting plate 5, the outer movable frame 4 and the storage box 2 are lifted off the ground by the longitudinal telescopic mechanism A6 extension, and the outer movable frame 4 on the mounting plate 5 is slid under the action of the limited sliding of the slider A15 and the T-shaped slide 14. After moving, the longitudinal telescopic mechanism A6 contracts to make the outer movable frame 4 contact with the ground and separate the longitudinal telescopic mechanism A6 from the ground. After separation, under the action of the limited sliding of the slider A15 and the T-shaped slide 14, the mounting plate 5 on the outer movable frame 4 and the storage box 2 on it are slid to cross the uneven place, thereby avoiding the problem of being difficult to move or prone to tipping during the movement.

[0039] See also Figure 3-4 The cross bar 11 is located on either side of the length direction of the slide groove 16, and a limit block 17 is arranged along the length direction of the cross bar 11. The slider A15 is provided with a slider B18 that cooperates with the slide groove 16, and the slider B18 is rotatably provided with a limit buckle 19 that cooperates with the limit block 17.

[0040] In practice, when the limit buckle 19 corresponds to the limit block 17 and needs to be fixed, the limit buckle 19 can be rotated to be set on the limit block 17 to limit the sliding fixation, otherwise, the fixation is released. The purpose of providing the slide grooves 16 on both sides of the T-shaped slide groove 14 is to facilitate the sliding cooperation with the slider B15, and also to facilitate the limit buckle 19 on the slider B15 to cooperate with the limit block 17 to play the role of fixing the installation plate 5 and the storage box 2, etc., to prevent them from sliding.

[0041] The slider A15 and the slider B18 are one or more. When there is one, the slider A15 is arranged at the middle position of the edge side of the mounting plate 5, and the slider B18 is arranged at the middle position of the edge position of the slider A15. When there are multiple sliders, the sliders A15 are arranged at equal intervals on the edge side of the mounting plate 5, and the sliders B18 are correspondingly arranged at the middle position of the edge position of each slider A15.

[0042] In some embodiments, the vertical rod 12 is a longitudinal telescopic mechanism B.

[0043] When working, the longitudinal telescopic mechanism B can be a hydraulic telescopic mechanism or a manual fixed telescopic structure. The purpose of limiting the vertical rod 12 as the longitudinal telescopic mechanism B is to facilitate the adjustment of the height of each corner of the outer movable frame 4 according to the position corresponding to each vertical rod 12, so as to avoid the outer movable frame 4 from being tilted, thereby making it difficult to move components such as the mounting plate 5 and affecting the stability during the movement.

[0044] In some embodiments, the outer movable frame 4 is provided with a sliding push-pull rod A7, and the mounting plate 5 is provided with a sliding push-pull rod B8.

[0045] During operation, the sliding push-pull rod A7 and the sliding push-pull rod B8 are provided to facilitate the movement of the storage box 2 on the outer movable frame 4 and the mounting plate 5 .

[0046] In practice, the mounting plate 5, the outer movable frame 4 and the storage box 2 are lifted off the ground by extending the longitudinal telescopic mechanism A6, and the rotating mechanism 9 is started to rotate at the same time to rotate the outer movable frame 4, the mounting plate 5 and the storage box 2. After the rotation, under the action of the limiting sliding of the slider A15 and the T-shaped slide groove 14, and the limiting sleeve 19 is released, the outer movable frame 4 on the sliding mounting plate 5 is slid. After the movement, the longitudinal telescopic mechanism A6 contracts to make the outer movable frame 4 contact with the ground and separate the longitudinal telescopic mechanism A6 from the ground. After separation, under the action of the limiting sliding of the slider A15 and the T-shaped slide groove 14, the mounting plate 5 on the outer movable frame 4 and the storage box 2 thereon are slid and fixed by the limiting sleeve 19 and the limiting block 17 to cross the uneven place, thereby avoiding the problem of difficulty in moving or easy tipping during movement.
