Description

Technical Field

[0001] This utility model relates to the field of extrusion pile inspection tools, and in particular to a portable tool for detecting the expansion degree of extrusion pile discs. Background Technology

[0002] As a core construction parameter, the expansion degree of the bearing plate directly determines the forming quality of the bearing plate cavity and the bearing capacity of the pile. Measuring it is a crucial means to ensure project safety.

[0003] Existing testing tools are cumbersome and inconvenient to operate due to their unreasonable structural optimization design. They cannot be retracted to reduce their size when idle, resulting in poor portability. In addition, the lack of an auxiliary guiding structure leads to significant frictional resistance between the testing tool and the inner circumference of the pile hole when inserting the testing tool into the pile hole during the testing process, making it difficult to insert the testing tool into place. Utility Model Content

[0004] In view of this, the present invention provides a portable tool for detecting the expansion degree of the expansion bearing disc for extruded expansion bearing disc piles, so as to solve the problem of inconvenience in inserting the detection tool into place.

[0005] The technical solution proposed by this utility model is as follows: a portable tool for detecting the expansion degree of a spur plate pile, specifically including a vertical handle, in which a vertical drive shaft is slidably installed by means of a spring push; a mounting plate is welded to the bottom end of the vertical handle, and a ring of expansion rods is rotatably connected to the outer edge of the mounting plate; a circular mounting plate is welded to the bottom end of the vertical drive shaft, and a ring of expansion rods is rotatably connected to the outer edge of the circular mounting plate, with the head end of the expansion rod rotatably connected to the head end of the expansion rod; the pile hole is drilled on the foundation by an external drilling rig, and the spur plate cavity is drilled in the pile hole by an external hydraulic expansion mechanism; the ring of expansion rods and the ring of expansion rods are connected together to form a retractable cage-shaped measuring mechanism, which presents a symmetrical cone-shaped structure when unfolded, and is used to measure the diameter of the spur plate cavity; the upper half of the vertical drive shaft has a scale on its outer periphery for indicating the diameter of the spur plate cavity.

[0006] Furthermore, a bushing is welded above the vertical handlebar, and a visible space is formed between the bushing and the top of the vertical handlebar.

[0007] A tightening bolt is screwed through the thread on the circumferential wall of the bushing, and the head end of the tightening bolt is pressed against and in contact with the vertical drive shaft.

[0008] Furthermore, a limiting plate is welded to the top of the vertical drive shaft, and a spring that pushes the vertical drive shaft is fitted onto the vertical drive shaft and compressed and clamped between the limiting plate and the bushing.

[0009] Furthermore, two guide wheels are symmetrically and rotatably mounted on the front end of the expansion rod.

[0010] Furthermore, during the measurement process, when the testing tool is inserted into the pile hole, the cage-shaped measuring mechanism remains in a retracted state, and the guide wheel abuts against the peripheral wall of the pile hole.

[0011] Furthermore, when the cage-shaped measuring mechanism is inserted into the support plate cavity, it is switched to the expanded state, and the guide wheel abuts against the peripheral wall of the largest diameter part of the support plate cavity.

[0012] The portable tool for detecting the expansion degree of extruded and expanded bearing piles provided by this utility model has the following beneficial effects:

[0013] I. In this utility model, the cage measuring mechanism can be retracted by sliding the vertical drive shaft upwards, and the retracted cage measuring mechanism can be inserted into the pile hole. Then, the retracted cage measuring mechanism can be pushed into the support plate cavity, so that the cage measuring mechanism can automatically expand and unfold. Finally, the scale on the vertical drive shaft can be read through the visible space between the bushing and the top of the vertical handle to complete the measurement of the diameter of the support plate cavity (i.e., the expansion degree of the support plate). The operation is relatively simple, convenient and efficient.

[0014] Second, tightening the bolts can tighten and position the vertical drive shaft in the working state after it has been pressed down and slid, so that the cage measuring mechanism remains in the retracted state when idle. This can reduce the size of the measuring tool when idle, which is conducive to its portability.

[0015] Third, when inserting the cage-shaped measuring mechanism into the pile hole, the guide wheel can reduce the frictional resistance between the cage-shaped measuring mechanism and the inner circumference of the pile hole by means of its rolling and guiding effect, which makes it easier to push and insert the cage-shaped measuring mechanism into the pile hole smoothly and effortlessly.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please refer to Figures 1 to 7 Example 1:

[0032] This embodiment proposes a portable tool for detecting the expansion degree of a spur pile, including a vertical handle 3, through which a vertical drive shaft 4 is slidably mounted by means of a spring push; a mounting plate 301 is welded to the bottom end of the vertical handle 3, and a ring of expansion rods 303 is rotatably connected to the outer edge of the mounting plate 301; a circular mounting plate 401 is welded to the bottom end of the vertical drive shaft 4, and a ring of expansion rods 402 is rotatably connected to the outer edge of the circular mounting plate 401, with the head end of the expansion rod 402 rotating with the head end of the expansion rod 303. Dynamic connection; the pile hole 1 is drilled on the foundation by an external drilling rig, and the support plate cavity 2 is drilled in the pile hole 1 by an external hydraulic extrusion and expansion mechanism; a ring of expansion rod 402 and a ring of expansion support rod 303 are connected together to form a retractable cage-shaped measuring mechanism. When the cage-shaped measuring mechanism is unfolded, it presents a symmetrical cone-shaped structure and is used to measure the diameter of the support plate cavity 2; the upper half of the vertical drive shaft 4 has a scale on its outer periphery to indicate the diameter of the support plate cavity 2. The unit of the scale is centimeters. The support plate on the extrusion and expansion support plate pile is cast in the support plate cavity 2.

[0033] Preferably, a bushing 302 is welded above the vertical handlebar 3, and a visible space is formed between the bushing 302 and the top of the vertical handlebar 3.

[0034] A tightening bolt 3021 is screwed through the thread on the peripheral wall of the bushing 302, and the head end of the tightening bolt 3021 is pressed and abutted against the vertical drive shaft 4.

[0035] Preferably, a limiting disk 403 is welded to the top of the vertical drive shaft 4, and a spring that pushes the vertical drive shaft 4 is fitted onto the vertical drive shaft 4 and compressed and clamped between the limiting disk 403 and the bushing 302.

[0036] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0037] Two guide wheels 4021 are symmetrically rotated and installed at the head end of the expansion rod 402. During the measurement process, when the testing tool is inserted into the pile hole 1, the cage-shaped measuring mechanism remains in the retracted state, and the guide wheels 4021 abut against the peripheral wall of the pile hole 1. When the cage-shaped measuring mechanism is inserted into the support plate cavity 2, it is switched to the expanded state, and the guide wheels 4021 abut against the peripheral wall of the largest diameter part of the support plate cavity 2.

[0038] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below:

[0039] The cage-shaped measuring mechanism is essentially a multi-link extension and retraction mechanism. Based on the mechanical transmission principle of this mechanism, the sliding vertical drive shaft 4 and the circular mounting plate 401 can drive a ring of expansion rods 303 and 402 to rotate in opposite directions, controlling the extension and retraction of the multi-link mechanism. The spring on the vertical drive shaft 4 can push and drive it upwards through its counterforce, controlling the cage-shaped measuring mechanism to extend and measure the diameter of the support cavity 2. In use, first, the vertical drive shaft 4 is slid down by hand, driving the cage-shaped measuring mechanism to the retracted state. The retracted cage-shaped measuring mechanism is then inserted into the pile hole 1. When the vertical drive shaft 4 is slid down, the spring on it is compressed by the limiting plate 403. Then, the hand is released from the vertical drive shaft 4 to release the retracted holding force indirectly applied to the cage-shaped measuring mechanism by the hand through the vertical drive shaft 4. At this time, the cage-shaped measuring mechanism and... The vertical drive shaft 4 returns to its free state. Under the rebound push of the springs, the vertical drive shaft 4 tends to slide upwards and expand the cage-shaped measuring mechanism. However, because the guide wheel 4021 simultaneously abuts against the inner circumference of the pile hole 1, it restricts the deformation and expansion of the cage-shaped measuring mechanism. Consequently, the cage-shaped measuring mechanism remains confined in a contracted state by the inner circumference of the pile hole 1 until it is pushed into the support cavity 2. Once the contracted cage-shaped measuring mechanism is inserted into the support cavity 2, it disengages from the inner circumference of the pile hole 1 and is placed in the suddenly enlarged open environment of the support cavity 2. At this point, the contracted cage-shaped measuring mechanism and the vertical drive shaft 4 lose the limiting force from the pile hole 1. The vertical drive shaft 4 can be pushed upwards by the compressed springs on it, gradually automatically expanding the cage-shaped measuring mechanism, causing it to present a symmetrical conical expansion shape that fills the support cavity 2 (see reference). Figure 2 In this state, the guide wheel 4021 abuts against the inner circumference of the largest diameter portion of the support cavity 2. Thus, the diameter of the cage-like measuring mechanism filling the support cavity 2 can be used to measure the diameter of the support cavity 2, which represents the expansion degree of the support. The diameter of the support cavity 2 is twice the distance from the guide wheel 4021 to the axis of the vertical drive shaft 4. Because the cage-like measuring machine slides towards or away from the axis of the vertical drive shaft 4 during expansion and contraction, and the vertical drive shaft 4, in turn, drives the cage-like measuring mechanism to expand and contract through its up-and-down sliding motion, the guide wheel 4021... 1. When measuring the diameter of the support cavity 2, the sliding distance away from or towards the axis of the vertical drive shaft 4 can be proportionally mapped to the vertical sliding amount of the vertical drive shaft 4. Thus, during the measurement process, the diameter of the support cavity 2 and the expansion degree of the support can be measured by the upward sliding amount of the vertical drive shaft 4 when the cage-shaped measuring mechanism is in the support cavity 2. The scale on the vertical drive shaft 4 is used to represent the expansion degree of the support in terms of the sliding amount of the vertical drive shaft 4. After the proportional mapping between the sliding amount and the scale, the scale on the vertical drive shaft 4 can essentially represent the expansion degree of the support.

[0040] In summary, in this utility model, the cage measuring mechanism can be retracted by sliding the vertical drive shaft 4 upwards, and the retracted cage measuring mechanism can be inserted into the pile hole 1. The retracted cage measuring mechanism can then be pushed into the support plate cavity 2, causing the cage measuring mechanism to automatically expand. Finally, the scale on the vertical drive shaft 4 can be read through the visible space between the bushing 302 and the top of the vertical handle 3 to complete the measurement of the diameter of the support plate cavity 2 (i.e., the expansion degree of the support plate). The operation is relatively simple, convenient and efficient.

[0041] The tightening bolt 3021 can tighten and position the vertical drive shaft 4 in the working state after it is pressed and slid down, so that the cage measuring mechanism remains in the retracted state when idle. This can reduce the size of the measuring tool when idle, which is conducive to its portability.

[0042] When the cage-shaped measuring mechanism is inserted into the pile hole 1, the guide wheel 4021 can reduce the frictional resistance between the cage-shaped measuring mechanism and the inner circumference of the pile hole 1 by means of its rolling guiding effect, so as to facilitate the smooth and labor-saving pushing and inserting of the cage-shaped measuring mechanism into the pile hole 1.
