Description

Technical Field

[0001] This utility model relates to the field of road construction engineering, and in particular to a ring-type inclined bracing reinforcement device for a high-pressure jet grouting pile machine. Background Technology

[0002] During road construction, some areas are soft soil areas, which are prone to settlement. It is necessary to reinforce or drive piles to ensure that the soft soil has sufficient bearing capacity to meet the road surface specifications. This involves a large amount of pile driving work. If high-pressure jet grouting piles are used for reinforcement, high-pressure jet grouting pile machines will be used.

[0003] High-pressure jet grouting pile machines typically weigh 6-10 tons and are about 5 meters tall. Due to their heavy weight and high center of gravity, their weight is usually supported by the bottom tracks and four outriggers at the corners. In soft, silty soils with low bearing capacity, uneven settlement can easily occur under load, causing the high-pressure jet grouting pile machine to overturn. This not only delays construction but can also injure on-site workers. Existing measures to prevent overturning typically involve adding a pad to each of the four outriggers at the corners to increase the contact area with the ground and prevent excessive settlement that could lead to overturning. Additionally, reinforcement structures are often used to enhance the reinforcement effect.

[0004] However, when reinforcing the support column of a high-pressure jet grouting pile machine, the two semi-circular sleeves of the existing reinforcement device are prone to misalignment due to different installation terrain. Although the sliding position of the semi-circular sleeve on the surface of the telescopic outer rod can be adjusted, unevenness is likely to occur. This can affect installation efficiency or even the reinforcement effect, which is a major limitation. At the same time, construction workers often use a tape measure to directly measure the height difference on the ground or indirectly judge by observing the fit between the sleeve and the support column. This is not only cumbersome to operate, but also affected by other environmental factors, which affects the accuracy of the measurement. Utility Model Content

[0005] The main purpose of this utility model is to provide a ring-type inclined bracing reinforcement device for high-pressure jet grouting pile machines, which can effectively solve the problems of difficult alignment, complicated distance measurement, poor protection, and weak stability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A ring-type inclined brace reinforcement device for a high-pressure jet grouting pile machine includes a pad and a reinforcement frame. The pad and the reinforcement frame are fixedly connected. The device includes a mounting frame. An adjusting screw is rotatably connected to the inner wall of the mounting frame, and several limiting blocks are fixedly installed thereon. The pad is threaded onto the adjusting screw and slides against the inner wall of the mounting frame. A pointing rod is fixedly installed on the top of the mounting frame. A distance measuring component is fixedly installed on the top of the pad. When the adjusting screw rotates, it adjusts the vertical height of the pad and the reinforcement frame. The distance measuring component cooperates with the pointing rod to monitor the real-time movement distance of the pad and the reinforcement frame. A rotating handle is fixedly installed on the top of the adjusting screw.

[0007] Preferably, the ranging component includes a storage box, which is fixedly installed on the top of the pad. The inner wall of the storage box is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is rotatably connected to a fixing rod. The fixing rod has scale values ​​on both sides.

[0008] Preferably, the ranging component further includes a connecting plate, which is fixedly installed on the outer wall of the rotating shaft. The outer wall of the rotating shaft is provided with a torsion spring, and the two ends of the torsion spring are respectively connected to the outer wall of the storage box and one end of the connecting plate.

[0009] Preferably, a dustproof sleeve is fixedly installed on the outer wall of the storage box, and the torsion spring is located inside the dustproof sleeve.

[0010] Preferably, the storage box has sliding grooves on both sides, and a rotating rod is rotatably connected in one of the sliding grooves, with a limit rod fixedly sleeved on the outer wall of the rotating rod.

[0011] Preferably, four sliding rods are fixedly installed on the inner wall of the mounting frame, three of the limiting blocks are fixedly sleeved on the three sliding rods, nuts are fixedly sleeved on the outer wall of the sliding rods, and the pad is slidably sleeved on the outer wall of the sliding rods.

[0012] Preferably, a compression spring is sleeved on the outer wall of the slide rod, and the two ends of the compression spring are respectively connected to the inner wall of the pad and the bottom of the limiting block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By adjusting the screw, mounting frame and pad, the vertical height of the pad and reinforcement frame can be finely adjusted, which can effectively improve the overlap rate when the two reinforcement frames are spliced, improve the reinforcement effect, and can be installed in different terrains, effectively expanding the scope of application.

[0014] 2. By coordinating the pointing rod, adjusting screw, and ranging assembly, the screw is adjusted to rotate the adjusting pad and the vertical height of the reinforcement frame. After rotating the fixing rod to a vertical position, the operator can directly determine the terrain difference between the two mounting frame installation positions by pointing the pointing rod to the scale value on the surface of the fixing rod. This facilitates advance preparation for subsequent installation of other equipment or rework, effectively improving applicability. Furthermore, the torsion spring and limit rod work together to improve the rotation adjustment efficiency of the limit rod, reduce the difficulty of operation, and enhance applicability.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-5As shown, a ring-type inclined brace reinforcement device for a high-pressure jet grouting pile machine includes a pad 1 and a reinforcement frame 2, which are fixedly connected. The device includes a mounting frame 3, with an adjusting screw 4 rotatably connected to the inner wall of the mounting frame 3, and several limiting blocks 301 fixedly installed thereon. The pad 1 is threaded onto the adjusting screw 4 and slides against the inner wall of the mounting frame 3. A pointing rod 7 is fixedly installed on the top of the mounting frame 3, and a distance measuring component 6 is fixedly installed on the top of the pad 1. When the adjusting screw 4 rotates... Adjust the vertical height of the adjustable pad 1 and the reinforcing frame 2. The ranging component 6 cooperates with the pointing rod 7 to view the moving distance of the pad 1 and the reinforcing frame 2 in real time. The top of the adjusting screw 4 is fixedly installed with a rotating handle 5. The ranging component 6 includes a storage box 601, which is fixedly installed on the top of the pad 1. The inner wall of the storage box 601 is rotatably connected to a rotating shaft 602, and the outer wall of the rotating shaft 602 is rotatably connected to a fixing rod 603. The fixing rod 603 has scale values ​​610 on both sides.

[0019] By rotating the screw 4 to adjust the vertical height of the adjustable pad 1 and the reinforcing frame 2, when installing two reinforcing frames 2 on uneven ground, the two semi-ring sleeves can be aligned through fine-tuning, improving the locking effect and thus enhancing the applicability of the equipment. At the same time, when the fixing rod 603 is in a vertical state, the operator can directly determine the terrain difference between the installation positions of the two mounting frames 3 by pointing to the value on the scale 610 by the pointing rod 7. This facilitates the adjustment of the support height of other equipment in advance and the commencement of subsequent work, effectively improving applicability.

[0020] The reinforcement frame 2 is existing technology and will not be explained here.

[0021] like Figure 4 As shown, in one embodiment, the ranging component 6 further includes a connecting plate 605, which is fixedly installed on the outer wall of the rotating shaft 602. The outer wall of the rotating shaft 602 is provided with a torsion spring 606, and the two ends of the torsion spring 606 are respectively connected to the outer wall of the storage box 601 and one end of the connecting plate 605. The outer wall of the storage box 601 is fixedly installed with a dustproof cylinder 604, and the torsion spring 606 is located inside the dustproof cylinder 604. Both sides of the storage box 601 are provided with sliding grooves 607, and a rotating rod 608 is rotatably connected in one of the sliding grooves 607. A limit rod 609 is fixedly sleeved on the outer wall of the rotating rod 608.

[0022] The fixing rod 603 can be stored in the storage box 601. At the same time, the limiting rod 609 rotates and limits the fixing rod 603, reducing the probability of the fixing rod 603 being exposed and easily damaged when the equipment is not in use, thus improving the protection effect. Meanwhile, after the limiting rod 609 rotates, the torsion spring 606 releases pressure, which allows the fixing rod 603 to quickly rotate to a vertical position, reducing operation steps and improving applicability.

[0023] like Figure 1-3As shown, in one embodiment, four slide rods 302 are fixedly installed on the inner wall of the mounting frame 3, of which three limiting blocks 301 are fixedly sleeved on the three slide rods 302, and nuts 304 are fixedly sleeved on the outer wall of the slide rods 302. The pad 1 is slidably sleeved on the outer wall of the slide rods 302, and a compression spring 303 is sleeved on the outer wall of the slide rods 302. The two ends of the compression spring 303 are respectively connected to the inner wall of the pad 1 and the bottom of the limiting block 301.

[0024] The slide bar 302 can improve the stability of the pad 1 when it moves vertically, while several compression springs 303 can reduce the impact force when the top of the pad 1 is impacted, improve the protection effect, and extend the service life of the equipment.

[0025] Working principle: The workers place the installation frame 3 on the ground, then insert the support column of the high-pressure jet grouting machine between the semi-ring sleeves of two adjacent reinforcement frames 2, and then adjust the position of the two semi-ring sleeves on the outer wall of the telescopic outer rod until the two semi-ring sleeves are perfectly aligned. If there is unevenness due to uneven ground, the workers rotate the handle 5 and the adjusting screw 4. When the adjusting screw 4 rotates, it engages with the threaded pad 1, causing the pad 1 to drive the reinforcement frame 2 to move vertically until the two semi-ring sleeves are aligned. Finally, bolts are installed between the two semi-ring sleeves to lock them in place. After installation, the staff rotates the rotating rod 608. After the rotating rod 608 rotates the limiting rod 609, the limiting rod 609 no longer limits one side of the fixed rod 603. At this time, the torsion spring 606 releases pressure, causing the fixed rod 603 to rotate to a vertical state. At this time, the staff can directly check the value of the scale 610 on the surface of the fixed rod 603 by pointing the pointing rod 7 to the horizontal position of the fixed rod 603, and detect the terrain difference between the installation areas of the two mounting frames 3.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
