Description

Technical Field

[0001] This utility model belongs to the technical field of civil engineering construction equipment, specifically relating to a fluidized solidified soil injection device in a confined space. Background Technology

[0002] A backfill trench refers to the extra section excavated to provide a working surface. Generally, it refers to the space between the outer wall of the basement or foundation of a building and the edge of the excavation pit. In construction engineering, backfilling the backfill trench is an important step in ensuring the stability and safety of the building. The backfill trench can be filled with fluidized solidified soil or concrete, thus eliminating the need for compaction and greatly improving construction efficiency. Fluidized solidified soil mixing equipment is relatively large and therefore needs to be placed in an open space. However, due to the influence of the construction site, a grouting pipe is generally used to guide the prepared fluidized solidified soil to the backfill trench. However, construction sites are generally not flat enough and require support for the grouting pipe. Current technology does not have a support device that can be used quickly in narrow areas.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] like Figure 1 As shown, a fluidized solidified soil injection device in a confined space mainly provides a support structure for supporting the fluidized solidified soil injection pipe. It includes a base frame and a support mechanism. The base frame is placed on the ground, and the support mechanism is set above the base frame to limit the injection pipe. The support mechanism includes a base 1, a support member 4, a first support arm 3, and a second support arm 5. The base 1 can be a disc. A rotating shaft 2 is provided below the base 1. The base 1 is rotatably connected to the upper end of the base frame through the rotating shaft 2, so that it can be rotated according to actual needs. The two first support arms 3 are respectively hinged to both sides of the base 1 and are symmetrically distributed about the base 1.

[0022] One end of each of the two second support arms 5 is hinged to both sides of the support member 4 and is symmetrically distributed about the support member 4. The other end of each of the two second support arms 5 is hinged to the middle of the two first support arms 3. The length of the second support arm 5 is less than the distance between the hinge point of the first support arm 3 and the base 1, so that the second support arm 5 can drive the first support arm 3. Specifically, after the injection tube is placed above the support member 4, the two first support arms 3 are pulled by the second support arm 5 to rotate toward the injection tube, thereby forming a V-shaped support structure to limit the injection tube.

[0023] In an optional embodiment, an elastic element, which can be a spring 6, is provided between the base 1 and the support 4. The spring force of the spring 6 is less than the weight of the infusion tube applied to the support 4, so that the infusion tube can drive the first support arm 3 by its own weight. Furthermore, when the infusion tube is lifted upward, the elastic element drives the support 4 and the first support arm 3 to return to their original positions, facilitating the removal of the infusion tube. Further, a mounting groove corresponding to the elastic element is provided on the upper surface of the base 1, thereby ensuring the compactness and stability of the spring 6 installation. The support 4 can be a disc or a plate-like structure.

[0024] In an optional embodiment, the non-hinged end of the first support arm 3 is provided with a limiting arm 7, which can further stop the infusion tube. The limiting arm 7 extends above the support member 4 in a direction perpendicular to the first support arm 3. The length of the limiting arm 7 is designed according to the actual diameter of the infusion tube and the length of the first support arm 3, so that the limiting arm 7 can stop above the infusion tube.

[0025] The limiting arm 7 is slidably assembled along the first support arm 3 to ensure the blocking of the injection tube. Specifically, the limiting arm 7 is slidably assembled on the upper end of the first support arm 3 through a sleeve. A bolt is provided on the sleeve, and the bolt passes through the sleeve and tightens against the first support arm 3.

[0026] Alternatively, a dovetail groove corresponding to the limiting arm 7 is provided on the first support arm 3. The limiting arm 7 slides in the dovetail groove through a dovetail-shaped slider. A bolt is provided on the slider. After the bolt passes through the sleeve, it is pressed against the inner wall of the dovetail groove.

[0027] In an optional embodiment, the base frame includes a tube 9 and legs 10. The tube 9 is a metal tube with a diameter adapted to the pivot 2, so that the tube 9 can be fitted onto the pivot 2. Multiple legs 10 are arranged on the outer periphery of the tube 9 to support the tube 9. There can be three legs 10. For better convenience, the legs 10 are configured as folding structures. The upper end of the legs 10 is hinged to the upper middle part of the tube 9, and the lower middle part of the legs 10 is hinged to a connecting rod 11. The connecting rod 11 is correspondingly hinged to a sliding sleeve 12. The sliding sleeve 12 is slidably assembled on the lower end of the tube 9, so that the legs 10 can be folded to the outside of the tube 9, or unfolded and limited by the sliding sleeve 12 to ensure support capacity.

[0028] Furthermore, the rotating shaft 2 is connected to a threaded sleeve 8 via an external thread. The threaded sleeve 8 is supported on the upper end of the pipe body 9. By rotating the threaded sleeve 8, the height of the rotating shaft 2 can be adjusted to accommodate different height positions, ensuring that the fluidized solidified soil inside the injection pipe can be smoothly guided to the fertilizer tank. A lever arm extending radially is provided on the threaded sleeve 8.

[0029] The above description is only a preferred embodiment of the present utility model and is 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 within the scope of protection of the pending claims of the present utility model.
