[0040] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation to the present application.

[0041] In this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0042] As described in the background art, in traditional brackets, tripod brackets or independent support rods are mostly used. Among them, when using an independent support rod, at least one staff member is required to hold it to ensure stability (mainly to avoid tipping over); while the tripod bracket is used the most and can free the hands of the staff and avoid the staff from holding the tripod bracket; however, the disadvantage of the traditional tripod bracket is that when used outdoors, due to different ground scenarios, the tripod bracket is not installed smoothly enough and has low adaptability; the traditional tripod bracket is more suitable for scenarios with relatively flat ground. For a gravel ground, the support at the bottom is prone to instability.

[0043] For the above reasons, this embodiment provides an engineering survey device, as Figure 1 shown, the device includes a measuring host 200 and a tripod bracket 100; the measuring host can be a theodolite or a level or a plane table or a rangefinder; as Figures 2 - 5As shown, the tripod 200 includes a support part and a mounting part 101. The support part includes a support disk 104 and three support legs 105 mounted on the support disk. The mounting part 101 is installed on the support disk 104 in a pitching rotation manner (i.e., rotatably installed, and the rotation direction is for adjusting the pitching angle of the mounting part); the measurement host 200 is installed on the mounting part 101 through a mounting plate 102, and this mounting plate 102 is fixedly connected to the measurement host through a connecting piece (such as a screw);

[0044] A dovetail groove adapted to the mounting plate is formed on the mounting part 101. This dovetail groove is only open at one end. The mounting plate has a dovetail tenon matching the dovetail groove, and this dovetail tenon can be integrally formed by the mounting plate (that is: making the cross-section of the entire mounting plate trapezoidal to achieve the dovetail tenon);

[0045] Conical insertion blocks 108 are detachably installed at the bottoms of the three support legs 105.

[0046] The above technical features provide an engineering measurement device for collecting parameters (the parameters can be determined according to the type selection of the measurement host) in engineering. This engineering measurement device improves the stability of the tripod in the use scenario of gravel ground in outdoor environments through the improvement of the tripod; by setting detachable conical insertion blocks at the bottoms of the support legs, the adaptability of the tripod to the use site can be improved, especially for gravel ground, as Figure 13 shown. The conical insertion blocks can be inserted into the lower part (soil layer 500) of the gravel ground to improve the smoothness, while the traditional bracket 600 is prone to sliding on the gravel ground; at the same time, the conical insertion blocks are also suitable for the soil surface, and the conical insertion blocks can be well positioned and installed on the soil surface; and on a hard surface (such as a cement floor or other surfaces where a hard conical surface is not suitable), the staff can remove the conical insertion blocks, and at this time, the hard surface can be contacted through the contact part. At the same time, by installing the measurement host through the mounting plate, the quick installation and disassembly of the measurement host can be realized. Through the tenon and groove fit, the installation and disassembly are simple; in order to prevent the mounting plate from slipping out of the dovetail groove when adjusting the pitching angle of the mounting part; in the design, the clearance size is controlled by controlling the clearance fit between the dovetail tenon and the dovetail groove to reduce the risk of slipping; or a retaining pin is inserted into the open end of the dovetail groove to prevent the measurement host from slipping.

[0047] In order to adapt to sites with height differences, in one embodiment, as Figure 3 and Figure 5As shown, the support leg 105 includes a main body rod 106 and a telescopic rod 107. The telescopic rod 107 is slidably installed on the main body rod 106. At the bottom of the telescopic rod is a contact portion 1071, and the conical insertion block 108 is installed on the contact portion 1071. The telescopic rod penetrates through the main body rod, and the sliding degree between the main body rod and the telescopic rod is controlled by means of clearance fit to prevent the telescopic rod from automatically sliding under the action of gravity or without external force.

[0048] The above technical features can enable the support leg to be telescopic, thereby changing the height of the bracket and realizing the adjustment of the installation height of the measurement host. Moreover, the height of each support leg can be changed, and it can also be used on a ground with a height difference (such as a stepped ground).

[0049] In order to achieve the detachable installation of the conical insertion block, as Figure 5 and Figure 6 shown, in an embodiment, the conical insertion block 108 includes a conical block 1083 and a threaded rod 1081. The threaded rod 1081 is fixed to the upper end of the conical block, and the threaded rod is installed on the support portion in a threaded connection manner.

[0050] The above technical features can achieve the quick installation and disassembly of the contact portion, and can also achieve fine adjustment of the height of the conical insertion block, making it easy to adapt to gravel of different depths.

[0051] Since the surface of the conical block is a conical surface, it is not convenient to rotate when installing the conical insertion block. Therefore, in order to facilitate the staff to rotate the conical block when loading and unloading the conical insertion block, in an embodiment, a polygonal convex portion 1082 is formed on the conical block 1083. By designing the polygonal convex block, it is convenient for the staff to control the rotation of the conical block, thereby facilitating the loading and unloading of the conical insertion block.

[0052] In order to facilitate the control of the pitching angle of the measurement host, in an embodiment, a handle 103 is provided on the mounting portion 101. The handle can facilitate the adjustment of the pitching angle of the mounting portion.

[0053] Since most engineering surveys are carried out outdoors and the staff mostly reach the destination on foot, in order to facilitate the carrying of the tripod and the conical insertion block (because the conical insertion block is not used in any site), in an embodiment, the engineering survey device further includes a tripod storage box 300. The tripod storage box includes a box body 301 and a box cover 302. A soft protection block 303 with a tripod storage cavity 304 is placed in the box body.

[0054] A conical insertion block placement box 400 that is clamped to the protection block is provided on the tripod storage box.

[0055] The conical insertion block placement box 400 includes a strip box 401 and a strip box cover 402. Inside the strip box, there is a soft strip protection block 403 with three protection cavities.

[0056] Through the above technical features, it is convenient to carry the tripod and the conical insertion block, and it can also protect the tripod and the conical insertion block. Especially for the conical insertion block, because the bottom of the conical insertion block is relatively sharp, if it is not well protected, or the placement is unreasonable when the tripod moves, it is easy to scratch other devices or even the staff; while the conical insertion block placement box is designed or placed separately. The purpose is that when the staff carries the tripod, they do not necessarily carry the tripod storage box, but the conical insertion block needs to be carried. If the conical insertion block is installed on the support leg, it is easy to bring the above safety problems; so designing or placing the conical insertion block placement box separately can facilitate the staff to carry and protect the conical insertion block.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
