[0001] This utility model relates to the field of engineering surveying technology, specifically to a field surveying pole used in engineering design. Background Technology

[0002] Before conducting engineering design, it is necessary to survey the terrain and landforms of the site to obtain site topographic data, which facilitates engineering construction design. Site surveys are usually conducted using surveying instruments. To maintain the stability of the surveying instrument, it is usually mounted on a surveying pole, which is supported on the ground to fix the instrument in place, thus ensuring the accuracy of the survey data. However, existing surveying poles cannot use different support methods for different terrains to improve survey efficiency. Utility Model Content

[0003] In order to overcome the problems existing in the background art, this utility model provides a field survey pole for engineering design, so as to solve the technical problem mentioned in the background art that the existing survey poles cannot use different support methods according to different terrains, thereby improving the efficiency of surveying.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A field surveying pole for engineering design includes a support plate 1, support rods 2, and a fixing plate 3. Three support rods 2 are provided, with their upper ends hinged to the bottom of the fixing plate 3. One support rod 2 is fixedly connected to the support plate 1 at its lower end, while the lower ends of the other two support rods 2 are detachably connected to the support plate 1. A support frame 4 is also provided on the support plate 1, with a threaded fixing rod 5 threadedly connected to the top of the support frame 4. A through hole 6 is provided on the support plate 1 for the threaded fixing rod 5 to pass through, and a handle 501 is provided at the upper end of the threaded fixing rod 5 for easy rotation. A surveying instrument 8 is mounted on the fixing plate 3 via an adjustment mechanism 7.

[0006] Preferably, the support rod 2 is a telescopic rod structure, including a sleeve 201, an inner rod 202 and a locking knob 203. The inner rod 202 is telescopically inserted into the sleeve 201, and the inner rod 202 is locked by the locking knob 203 threaded to the side wall of the sleeve 201.

[0007] Preferably, the support plate 1 is provided with two arc-shaped limiting pieces 9 that limit the movement of the other two support rods 2.

[0008] Preferably, the adjusting mechanism 7 includes a fixed cylinder 701, an adjusting rod 702, a hexagonal adjusting block 703, a connecting column 704, and a mounting plate 705; the fixed cylinder 701 is fixedly connected to the fixed plate 3, the adjusting rod 702 is threadedly connected inside the fixed cylinder 701, and the hexagonal adjusting block 703 is fixedly connected to the upper end of the adjusting rod 702; the connecting column 704 is rotatably connected to the hexagonal adjusting block 703 through a bearing, the mounting plate 705 is mounted on the upper end of the connecting column 704 through a damping shaft, and the surveying instrument 8 is mounted on the mounting plate 705.

[0009] The beneficial effects of this utility model are as follows: When used on soft ground such as soil, the surveying rod is fixed by inserting the threaded fixing rod 5 into the ground. When the surveying rod is used on gravel or other places where it is difficult to insert the threaded fixing rod 5, the three support rods 2 can be opened and supported on the ground to fix the surveying rod, thereby providing stable support for the surveying instrument 8. The surveying rod can use different support methods according to different terrains, which increases the application range of the surveying rod and thus improves the efficiency of surveying.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] like Figure 1-4As shown, this utility model provides a field surveying pole for engineering design, including a support plate 1, support rods 2, and a fixing plate 3; three support rods 2 are provided, and the upper ends of the three support rods 2 are all hinged to the bottom of the fixing plate 3; one support rod 2 is fixedly connected to the support plate 1 at its lower end, and the lower ends of the other two support rods 2 are detachably connected to the support plate 1; a support frame 4 is also provided on the support plate 1, and a threaded fixing rod 5 is threadedly connected to the top of the support frame 4; a through hole 6 is provided on the support plate 1 for the threaded fixing rod 5 to pass through, and a handle 501 is provided at the upper end of the threaded fixing rod 5 to facilitate rotation of the threaded fixing rod 5; a surveying instrument 8 is installed on the fixing plate 3 through an adjustment mechanism 7. When using this surveying rod, the surveying instrument 8 is mounted on the fixing plate 3. When on relatively soft ground, the support plate 1 is placed upright on the ground. By rotating the threaded fixing rod 5 through the handle 501, the support plate 1 can be stepped on and the threaded fixing rod 5 can be rotated to allow it to pass through the through hole 6 on the support plate 1 and drill into the ground, thus fixing the surveying rod to the ground. Then, the surveying instrument 8 is used to survey the terrain. When the surveying rod is used in gravel or other places where it is difficult to insert and fix the threaded fixing rod 5, the three support rods 2 can be opened and supported on the ground to fix the surveying rod, thus providing stable support for the surveying instrument 8. The surveying rod can use different support methods according to different terrains, increasing the range of applications of the surveying rod and thus improving the efficiency of the survey.

[0016] The support rod 2 is a telescopic rod structure, including a sleeve 201, an inner rod 202, and a locking knob 203. The inner rod 202 is telescopically inserted into the sleeve 201, and is locked by the locking knob 203 threaded to the side wall of the sleeve 201. The support rod 2 is a telescopic structure; when the three support rods 2 are used separately, the length of each support rod 2 can be adjusted according to the terrain to ensure stable support for the surveying rod.

[0017] The support plate 1 is provided with two arc-shaped limiting pieces 9 that limit the movement of the other two support rods 2. When the three support rods 2 are used together, the lower ends of the other two support rods 2 are inserted into the arc-shaped limiting pieces 9 and locked by the locking knob 203, thereby merging the three support rods 2. When the three support rods 2 are used separately, the locking knob 203 is released, the support rods 2 are shortened, and the three support rods 2 are used separately.

[0018] The adjustment mechanism 7 includes a fixed cylinder 701, an adjusting rod 702, a hexagonal adjusting block 703, a connecting column 704, and a mounting plate 705. The fixed cylinder 701 is fixedly connected to the fixed plate 705. The adjusting rod 702 is threadedly connected inside the fixed cylinder 701. The hexagonal adjusting block 703 is fixedly connected to the upper end of the adjusting rod 702. The connecting column 704 is rotatably connected to the hexagonal adjusting block 703 via a bearing. The mounting plate 705 is mounted on the upper end of the connecting column 704 via a damping shaft. The surveying instrument 8 is mounted on the mounting plate 705. By operating the hexagonal adjusting block 703, the adjusting rod 702 is threadedly rotated in the fixed cylinder 701, thereby adjusting the height of the surveying instrument 8. Then, by rotating the connecting column 704 via the bearing, the surveying direction of the surveying instrument 8 is rotated. Finally, the vertical surveying angle of the surveying instrument 8 is adjusted by connecting the mounting plate 705 to the damping shaft of the connecting column 704.

[0019] Work process:

[0020] When using the surveying rod, the surveying instrument 8 is installed on the fixing plate 3. When on relatively soft ground, the support plate 1 is placed upright on the ground. By rotating the threaded fixing rod 5 through the handle 501, the support plate 1 can be stepped on and the threaded fixing rod 5 can be rotated to allow the threaded fixing rod 5 to pass through the through hole 6 on the support plate 1 and drill into the ground, thereby fixing the surveying rod on the ground. Then, the surveying instrument 8 is used to survey the terrain. When the surveying rod is used in gravel or other places where it is difficult to insert and fix the threaded fixing rod 5, the three support rods 2 are opened and supported on the ground. The length of each support rod 2 is adjusted according to the terrain to make the surveying rod stable. Then, the surveying height, direction and angle of the surveying instrument 8 are adjusted through the adjustment mechanism 7.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
