Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are merely exemplary of the invention and are not intended to be exhaustive. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1:
an auxiliary device for detecting the quality of construction engineering, as shown in figures 1-4, comprises a left clamping piece 1 and a right clamping piece 2 which are used for extending into a drilling seam 10 and clamping a sample core 11. A width adjusting device for adjusting the distance between the left clamping piece 1 and the right clamping piece 2 is arranged between the left clamping piece 1 and the right clamping piece 2.
As shown in fig. 1-3, the inner wall of the bottom of the left clamping piece 1 is provided with a plurality of supporting pieces 3 for supporting the bottom of the sample core 11. The supporting sheet 3 is hinged with the bottom of the left clamping sheet 1, and a driving device for driving the supporting sheet 3 to rotate towards the bottom of the left clamping sheet 1 is arranged between the supporting sheet 3 and the left clamping sheet 1. A limiting device 4 which can keep the supporting sheet 3 horizontal after rotating is arranged between the supporting sheet 3 and the left clamping sheet 1.
As shown in fig. 5, when a cylindrical sample core 11 is vertically drilled from the surface of concrete 12 by using a drill according to the prior art, a cylindrical drill is used to drill a circular drill hole 10 concentric with the sample core 11 in the concrete 12, the side wall of the sample core 11 is separated from the concrete 12, and the bottom of the sample core 11 is connected with the concrete 12.
Use the utility model discloses when taking out appearance core 11, all insert in the brill seam 10 with the bottom of left clamping piece 1 and right clamping piece 2. As shown in fig. 1 and 2, when the left clip 1 is placed, since the width of the drilling seam 10 is small, the support plate 3 contacts with the sample during the placement process, so that the support plate 3 rotates upward, and the left clip 1 can be placed into the drilling seam 10.
Then, the left jaw 1 is struck to the right jaw 2 side at the side of the left jaw 1 opposite to the right jaw 2 using a hammer or other striking object, and the left jaw 1 serves as a pry bar to pry off the root of the sample core 11. After the sample core 11 is pried, the sample core is inclined towards one side of the right clamping piece 2, and the bottom of the sample core 11, which is positioned at one side of the left clamping piece 1, is lifted. As shown in FIG. 3, after the sample core 11 is inclined, the blade 3 does not contact with the sample core 11, and the blade 3 rotates under the action of the driving device and is kept horizontal under the action of the limiting device 4.
Next, the right clip 2 is fixed by hand or other means, and the distance between the left clip 1 and the right clip 2 is adjusted to be small by the width adjusting means. Because the right clamping piece 2 is fixed, in the adjusting process, the left clamping piece 1 moves towards one side of the sample core 11, so that the sample core 11 is clamped by the left clamping piece 1 and the right clamping piece 2, and the supporting piece 3 moves to the bottom of the sample core 11 at the moment.
And finally, the sample core 11 is pulled out of the drill seam 10 through the left clamping piece 1 and the right clamping piece 2, and the supporting piece 3 supports the bottom of the sample core 11 in the process of pulling out the sample core 11, so that the sample core 11 is prevented from sliding off.
The utility model discloses not only use left clamping piece 1 as the crowbar, moreover with the 11 prizes disconnected backs of appearance core, can directly practice thrift the operating procedure with 11 centre grippings of appearance core through left clamping piece 1 and right clamping piece 2, improve work efficiency. And when pulling out a kind core 11, the support sheet 3 avoids the kind core 11 from sliding off, the sampling is more convenient and labor-saving, and the work efficiency is high.
It should be noted that, in order to ensure the sample core 11 to be broken from the root, the left jaw 1 may be lengthened so that the bottom of the left jaw 1 may contact the bottom of the sample core 11, thereby breaking the sample core 11 from the root when the sample core 11 is pried.
Further, as shown in fig. 4, the width adjusting means is a lead screw 5 and a nut 6 engaged with the lead screw 5. The screw rod 5 penetrates through the left clamping piece 1 and the right clamping piece 2, and the nut 6 is connected to the other end of the screw rod 5 in a matching mode.
When adjusting the interval between left clamping piece 1 and the right clamping piece 2, only need to rotate nut 6 and can realize, simple structure, convenient to use.
Further, as shown in fig. 1 to 3, the blade 3 is plural. A plurality of supporting sheets 3 are uniformly distributed at the bottom of the left clamping sheet 1. A plurality of blades 3 can better hold the sample core 11. And the sample core 11 is uniformly stressed.
Further, the driving device is a torsion spring. The torsion spring has simple structure and low cost.
Further, as shown in fig. 3, the limiting device 4 is a limiting plate horizontally arranged at the bottom of the left clip 1. The limiting plate can limit the supporting sheet 3 to further rotate, so that the phenomenon that the supporting sheet 3 rotates too much and cannot well support the sample core 11 is avoided.
It should be noted that the position limiting device 4, the bottom of the left clip 1 and the supporting plate 3 are also right-angle hinges in the prior art.
Further, as shown in fig. 4, the thickness of the left clip 1 decreases from top to bottom in sequence, so that an inclined surface is formed on one side of the left clip 1 relative to the right clip 2. The sample core 11 is conveniently broken by prying.
Further, the inner wall of the left clamping piece 1 and/or the right clamping piece 2 is consistent with the outer wall of the sample core 11 in shape. Increase the utility model discloses with the area of contact of appearance core 11, make appearance core 11 can be dragged out better.
Further, as shown in fig. 4, a pull rod 9 for lifting the sample core 11 is vertically arranged on the top of the right jaw 2. The sample core 11 is easily removed from the drill slot 10.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
