Description

Technical Field

[0001] This invention relates to the field of building auxiliary equipment technology, and in particular to an installation auxiliary device for earth pressure gauges. Background Technology

[0002] Earth pressure gauge installation aids are generally used in the construction field. Their main function is to monitor the compressive stress of the diaphragm wall on the surrounding rock and soil. During installation, the stress-bearing surface of the earth pressure gauge installation aid needs to be in close contact with the soil.

[0003] In the prior art, for example, the bracket and its usage method for installing an auxiliary device for earth pressure gauges during deep foundation pit construction disclosed in patent document CN111997104A, the earth pressure gauge installation auxiliary device and its bracket are installed together on the reinforcing cage. After the reinforcing cage is lowered, the winch of the bracket is pulled by a steel wire rope, and the rotation of the winch drives the push rod forward, so that the earth pressure gauge installation auxiliary device at the front end of the push rod is in close contact with the soil. This method of using the rotation of the winch to drive the push rod forward has a small transmission ratio, which is not suitable for the rapid installation of the earth pressure gauge installation auxiliary device, reducing construction efficiency. In addition, the winch occupies the space of the reinforcing cage, affecting the construction quality. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an installation auxiliary device for earth pressure gauges to improve installation efficiency.

[0005] An installation auxiliary device for a soil pressure gauge according to an embodiment of the present invention includes a bracket, a bend, a slide, a traction rope, and a mounting plate. The bracket includes two horizontal tubes and two vertical rods, with the vertical rod vertically connected between them. The bend is mounted on the vertical rod, with one end opening upwards. The slide includes two sliding rods and two connecting rods, with the connecting rod vertically connected between them. The two sliding rods are slidably inserted into their respective horizontal tubes. The connecting rod has a connecting portion, and the other end of the bend faces the connecting portion. One end of the traction rope is connected to the connecting portion, and the other end of the traction rope passes through the opening at the other end of the bend and exits through the opening at the first end of the bend. When the traction rope is pulled, the sliding rod can slide forward within the horizontal tube. The mounting plate is connected to the front end of the lower sliding rod of the two sliding rods and is used to mount the soil pressure gauge.

[0006] It has at least the following beneficial effects: The sliding rod is slidably connected to the horizontal pipe, and then pulled by the traction rope, causing the sliding rod to slide inside the horizontal pipe. This allows the sliding rod to push the earth pressure gauge at its front end to fit tightly against the soil. Compared with the existing winch-driven method, this invention has a larger transmission ratio and eliminates the need for a complex winch design, reducing the space occupied by the steel cage and significantly improving the installation efficiency and construction space utilization of the earth pressure gauge. In addition, the support structure of the vertical rod connecting the horizontal pipe and the guide path of the curved pipe allow the traction rope to pull the two sliding rods evenly, avoiding the phenomenon of the sliding rod getting stuck in the horizontal pipe. The sliding connection between the two sliding rods and the two horizontal pipes makes the thrust uniform and enhances the stability of the sliding rod advancement.

[0007] According to some embodiments of the present invention, the upper horizontal tube of the two horizontal tubes has a first guide hole extending in the vertical direction, and the upper horizontal tube of the two sliding rods has a second guide hole extending in the vertical direction. The traction rope that passes through one end opening of the curved tube passes through the first guide hole and the second guide hole in sequence.

[0008] According to some embodiments of the present invention, the front end of the upper slide rod of the two slide rods is connected to a clamp for clamping the cable of the earth pressure gauge.

[0009] According to some embodiments of the present invention, the mounting plate is rotatably connected to the front end of the relatively lower slide rod, the rotation axis of the mounting plate extends in the left-right direction, the mounting plate can be tilted in the up-down direction, and the rotation center of the mounting plate is connected by bolts, which can lock the position of the mounting plate.

[0010] According to some embodiments of the present invention, the mounting plate is provided with a slot and a hook on one side for mounting the earth pressure gauge. The slot is used to engage the earth pressure gauge, and the hook is used to support the earth pressure gauge.

[0011] According to some embodiments of the present invention, a square protrusion is provided on the mounting plate, and a square recess is provided on the back plate of the earth pressure gauge to match the square protrusion. The earth pressure gauge is guided and installed into the slot through the square protrusion.

[0012] According to some embodiments of the present invention, the connecting rod is provided with a plurality of connecting parts, the plurality of connecting parts are evenly distributed on the connecting rod, each connecting part is connected to a traction rope, and the plurality of traction ropes converge and pass through the bend, the first guide hole and the second guide hole in sequence.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0020] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 4 This invention discloses an installation auxiliary device for an earth pressure gauge, comprising a bracket 100, a bend 200, a slide 300, a traction rope 400, and a mounting plate 500. The bracket 100 includes two horizontal pipes 110 and two vertical rods 120, with the vertical rod 120 vertically connected between the two horizontal pipes 110. The bend 200 is mounted on the vertical rod 120, with one end of the bend 200 opening upwards. The slide 300 includes two sliding rods 310 and two connecting rods 320, with the connecting rod 320 vertically connected between the two sliding rods 310. The two sliding rods 310 are slidably inserted into their respective horizontal pipes 110, and the connecting rod 320 is equipped with... A connecting part 321 is provided, and the other end of the bend 200 opens towards the connecting part 321; one end of the traction rope 400 is connected to the connecting part 321, and the other end of the traction rope 400 passes through the other end opening of the bend 200 and exits through the one end opening of the bend 200. When the traction rope 400 is pulled, the slide rod 310 can slide forward in the horizontal tube 110; the mounting plate 500 is connected to the front end of the lower slide rod 310 of the two slide rods 310, and the mounting plate 500 is used to install the earth pressure gauge.

[0023] It should be noted that the slide rod 310 is slidably connected to the horizontal pipe 110, and the slide rod 310 is pulled by the traction rope 400, so that the slide rod 310 slides inside the horizontal pipe 110. This allows the slide rod 310 to push the soil pressure gauge at its front end to be in close contact with the soil. Compared with the existing winch drive method, the present invention has a larger transmission ratio and eliminates the complex winch design, reducing the space occupied by the steel cage and significantly improving the installation efficiency and construction space utilization of the soil pressure gauge. In addition, the support structure 100 of the vertical rod 120 vertically connected to the horizontal pipe 110, together with the guide path of the bend 200, allows the traction rope 400 to pull the two slide rods 310 evenly, avoiding the phenomenon of the slide rods 310 getting stuck in the horizontal pipe 110. The sliding connection between the two slide rods 310 and the two horizontal pipes 110 makes the thrust uniform and enhances the stability of the slide rod 310's advancement.

[0024] In some embodiments, the horizontal tube 110 and the vertical rod 120 are welded to form an I-shaped support, while the sliding rod 310 and the connecting rod 320 are welded to form an I-shaped slide. The horizontal tube 110 can be replaced with a horizontal rod, which has a groove on its body. The sliding rod 310 is slidably connected to the groove of the corresponding horizontal rod. In use, the horizontal tube 110 or the horizontal rod is welded to the reinforcing cage, with the extension and retraction direction of the sliding rod 310 facing the soil to be monitored. Then, the traction rope 400 is operated to slide the sliding rod 310, thereby causing the earth pressure gauge on the mounting plate 500 to adhere tightly to the soil.

[0025] Reference Figure 3 The upper horizontal tube 110 has a first guide hole 111 extending vertically, and the upper sliding rod 310 has a second guide hole 311 extending vertically. The traction rope 400, which passes through one end opening of the bend 200, passes through the first guide hole 111 and the second guide hole 311 in sequence. It can be understood that the bend 200 guides the traction rope 400. One of the two openings of the bend 200 faces backward, and the other faces upward. This opening arrangement allows the sliding rod 310 to be pulled forward when the traction rope 400 is pulled upward, thus ensuring that the earth pressure gauge on the mounting plate 500 is in close contact with the soil. The bend 200 can be made of stainless steel or acetal. The roughness of the inner wall of the bend 200 is below Ra3.2, and the opening of the bend 200 has a rounded corner structure to prevent the traction rope 400 from being ground or cut by the opening of the bend 200.

[0026] In some embodiments, a clamp 312 is connected to the front end of the upper slide bar 310, the clamp 312 being used to hold the cable of the earth pressure gauge.

[0027] In some embodiments, a cable tie or magnetic snap is connected to the front end of the upper slide bar 310, which is used to secure the cable of the earth pressure gauge.

[0028] Reference Figure 3 and Figure 4 The mounting plate 500 is rotatably connected to the front end of the relatively lower sliding rod 310. The rotation axis of the mounting plate 500 extends in the left-right direction, and the mounting plate 500 can be adjusted in the up-down direction. The rotation center of the mounting plate 500 is connected by bolts 540, which can lock the position of the mounting plate 500. By adjusting bolts 540, the pitch angle of the mounting plate 500 can be controlled to adapt to soil surfaces with different inclination angles, ensuring that the earth pressure gauge is in full contact with the measured surface of the soil. The traction rope 400 is made of high-strength corrosion-resistant steel wire rope, and its outer layer is covered with a polytetrafluoroethylene sheath to reduce frictional resistance and improve service life.

[0029] In some embodiments, the mounting plate 500 has a slot 510 and a hook 520 on one side for mounting the earth pressure gauge. The slot 510 is used to engage the earth pressure gauge, and the hook 520 is used to support the earth pressure gauge. The slot 510 and the hook 520 work together to effectively prevent the earth pressure gauge from shifting or falling off during installation or monitoring, improving measurement accuracy and safety. The inner wall of the slot 510 has anti-slip textures to further enhance the clamping force on the earth pressure gauge. The hook 520 has an L-shaped structure with its end bent inward to prevent the earth pressure gauge from falling off due to vibration during construction. The bent part of the hook 520 is opposite to the opening direction of the slot 510, forming a bidirectional limit on the earth pressure gauge, ensuring that the earth pressure gauge is stably installed even under complex working conditions.

[0030] In some embodiments, the mounting plate 500 is provided with a square protrusion 530, and the back plate of the earth pressure gauge is provided with a square recess that matches the square protrusion 530. The earth pressure gauge is guided and installed into the slot 510 through the square protrusion 530. The square protrusion 530 and the slot 510 work together to enhance the connection stability.

[0031] In some embodiments, the connecting rod 320 is provided with a plurality of connecting portions 321 along its length. These connecting portions 321 are distributed at uniform intervals to ensure a balanced force distribution. Each connecting portion 321 may specifically adopt a groove, hole, or fixing pin structure for reliably connecting one end of a traction rope 400. A plurality of traction ropes 400 converge into a bundle on one side of the connecting rod 320 and pass sequentially through the inner cavity of the bend 200, the first guide hole 111, and the second guide hole 311 according to a preset path, forming a coherent transmission or traction layout. The other end of the traction rope 400 is connected to an external tensioning device, and the attachment state of the earth pressure gauge is dynamically controlled by adjusting the tension. The first guide hole 111 and the second guide hole 311 are coplanar to ensure a smooth running trajectory of the traction rope 400 and avoid eccentric loading. The entire structure is easy to assemble on the construction site and adapts to the long-term monitoring requirements in complex geological environments. Understandably, the first guide hole 111 and the second guide hole 311 are offset by a certain distance in the front-to-back direction. When the traction rope 400 is pulled, the traction rope 400 itself will also push the slide rod 310 until the first guide hole 111 and the second guide hole 311 are vertically aligned. This prevents the slide rod 310 from driving the earth pressure gauge to press the soil indefinitely, resulting in excessive pressure between the soil and the earth pressure gauge. The traction rope 400 also serves to limit the movement of the slide rod 310.

[0032] In some embodiments, both the horizontal tube 110 and the slide rod 310 are provided with pin holes 600, which are used to insert pins to lock the position of the slide rod 310. The pin holes 600 extend vertically, and the initial position of the slide rod 310 is adjusted according to actual monitoring needs, and the pins are inserted to fix the positions of the horizontal tube 110 and the slide rod 310. The pins cooperate with the pin holes 600 to achieve mechanical self-locking, preventing the slide rod 310 from moving unexpectedly during traction and improving the reliability of the device operation. After the earth pressure gauge is installed and adjusted to the predetermined working state, the slide rod 310 is locked by inserting the pins to ensure stability during the monitoring process.

[0033] In some embodiments, a plurality of pin holes 600 are provided on the slide rod 310 along the axial direction of the slide rod 310. The plurality of pin holes 600 can lock the slide rod 310 according to actual needs, ensuring the stability of the pressure of the slide rod 310 after contacting the soil.

[0034] In some embodiments, the horizontal tube 110 is made of seamless steel pipe, and the opening of the horizontal tube 110 is provided with a rounded corner structure (not shown in the figure). The use of seamless steel pipe to make the horizontal tube 110 and the provision of a rounded corner structure at the opening of the horizontal tube 110 are both to prevent the slide rod 310 from getting stuck in the tube during the sliding process and to ensure that the slide rod 310 slides smoothly.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
