Description

Technical Field

[0001] The present application relates to the field of engineering machinery devices, and in particular to a device that can quickly measure and verify the deviation of a pile hole. Background Art

[0002] With the continuous development of bridge construction technology, measurement methods and instruments are also changing with each passing day. Pile foundation construction is the basis of bridge engineering, and pile foundation construction is not limited by the number of templates. At the same time, punching pile machines still account for the majority of pile foundation construction machinery. Therefore, how to reduce the number of measuring stations and quickly and accurately determine the pile foundation deviation is the key direction of the development of pile foundation measurement technology.

[0003] In the traditional method of measuring the deviation of bored piles, a cross guard pile must be reserved when the casing is buried. When the deviation of the pile foundation needs to be measured during the pile foundation injection process, the cross guard pile is pulled out with a rope, and a square wood or steel plate is placed under the cross guard pile. After the total station establishes the measuring station and confirms that the target is visible, the prism tripod is placed at the center point of the cross guard pile, the bubble is leveled, and the measurement work is carried out.

[0004] (1) The traditional measurement method requires that the four guard piles are firm and reliable, but the impact of the pile hammer during the impact process will cause a large vibration, which can easily cause the guard piles to shift, resulting in inaccurate measurement results, and thus affecting the quality of the physical construction. In order to ensure that the guard piles do not shift, it is usually necessary to pour concrete at the bottom of the guard piles, which increases the material investment;

[0005] (2) The personnel need to stand on a square wood or steel plate to operate the triangular prism bracket and use a walkie-talkie to keep in touch with the station personnel while operating the triangular prism bracket. This method can easily cause the walkie-talkie, triangular prism bracket, and personnel to fall into the casing, posing a major safety hazard;

[0006] (3) Since each pile foundation requires personnel to operate the triangular prism bracket to pull the cross pile guard and level the points, when the project is started on a large scale, multiple targets need to be measured. Personnel must carry prisms back and forth between each pile foundation, and the measurement station also needs to be re-established, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0027] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0028] See also Figure 1 and Figure 2 The present application proposes a device that can quickly determine and verify the deviation of a pile hole. The pile hole positioning device 101 includes a first support frame 1012, a second support frame 1013, a positioning assembly 1011 and a fixing assembly 1021. The fixing assembly 1021 includes a first bolt 1014 and a second bolt 1015. The positioning assembly 1011 includes a monitoring prism 10111. One end of the first support frame 1012 is connected to the second support frame 1013 by the second bolt 1015, and the other end is provided with a monitoring prism 10111. Figure 4 As shown, a first slide groove 10121 is provided at a connection position between the first support frame 1012 and the first bolt 1014 , and a second slide groove 10122 is provided at a connection position between the first support frame 1012 and the second bolt 1015 .

[0029] When the present application is used, the second bolt 1015 is loosened so that the first support frame 1012 can move left and right, so as to adjust the extension length of the first support frame 1012. Similarly, the first bolt 1014 can also pass through the monitoring prism 10111 and the first slide groove 10121 respectively, and the monitoring prism 10111 is placed on the first support frame 1012. When the first bolt 1014 is loosened, the first bolt 1014 can move left and right, thereby driving the monitoring prism 10111 to move left and right. When the left and right positions are adjusted to the right, that is, the center position of the monitoring prism 10111 and the naturally vertical plumb line 10112 are on the same axis, the first bolt 1014 is tightened to fix the monitoring prism 10111 on the first support frame 1012. If the first positioning is successful, the center position of the pile hole can be determined. During the process, the deviation between the pile hammer and the designed position of the pile hole can be checked at a certain frequency, and adjustments can be made in time.

[0030] Optionally, the present application can be installed on a pile driver 1, so that the pile driver 1 has the function of quickly determining and verifying the deviation of the pile hole.

[0031] like Figure 2 As shown, the pile hole positioning device 101 includes a third support frame 1017, and the fixing assembly 1021 also includes a third bolt 1018. The third bolt 1018 includes a screw shaft. The second support frame 1013 is connected to the third support frame 1017 through the third bolt 1018. When in use, the third support frame 1017 can rotate around the screw shaft, and the third bolt 1018 can be loosened so that the third support frame 1017 can rotate around the screw shaft to adjust the angle of the instrument.

[0032] like Figure 3 As shown, the third support frame 1017 includes a vertical frame 10171, and the pile hole positioning device 101 includes an anti-skid washer 1016, which is arranged between the vertical frame and the second support frame 1013. The anti-skid washer 1016 can prevent the second support frame 1013 from slipping after tightening the third bolt 1018, and can also ensure that the second support frame 1013 does not rotate under the impact of external force, thereby reducing the detection error.

[0033] Specifically, the third support frame also includes a horizontal frame 10172, and the third support frame 1017 is provided with a reinforcing rib 1020, one end of the reinforcing rib 1020 is fixedly connected to the horizontal frame 10172, and the other end is fixedly connected to the vertical frame 10171. By arranging the reinforcing rib 1020 on the vertical frame and the horizontal frame of the third support frame 1017, it is beneficial to strengthen the overall stability of the device structure.

[0034] Specifically, a gasket 1019 is provided at the connection position between the third bolt 1018 and the second support frame 1013. By providing the gasket 1019 at the connection position between the third bolt 1018 and the second support frame 1013, it is beneficial to make the pressure more uniform when tightening the third bolt 1018, thereby reducing the risk of the third support frame 1017 being damaged.

[0035] like Figure 2 As shown, the positioning component 1011 also includes a plumb line 10112 and a pendant 10113. One end of the plumb line 10112 is fixed to the bottom of the first bolt 1014, and the other end is fixedly connected to the pendant 10113. When using this application, since the direction of gravity is always toward the center of the earth, the plumb line 10112 and the pendant 10113 will naturally droop in a vertical downward direction under the action of gravity, which is beneficial to improve the accuracy of measurement.

[0036] Specifically, a plurality of aiming lines 101111 are provided on the monitoring prism 10111, and the plurality of aiming lines 101111 intersect each other at one point, which facilitates the aiming and positioning of the total station and further improves the measurement accuracy.

[0037] Specifically, both ends of the first slide groove 10121 are configured to be arc-shaped, which is conducive to the first bolt 1014 being adapted to the first bolt 1014 when the first bolt 1014 moves to the outermost corner of the first slide groove 10121 .

[0038] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
