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

[0026] A survey device for road planning and design, such as Figure 1-Figure 3As shown, it includes a main pole 1, a signal receiver 2 fixedly installed above the main pole 1, an operating screen 3 fixedly installed on the side wall of the main pole 1, a roller 4 arranged at the bottom of the main pole 1 and connected by a stabilizing device, and a handle 5 arranged on the side wall of the main pole 1, wherein the signal receiver 2 adopts a GNSS receiver. When in use, the surveyor holds the handle 5 to drive the entire survey device to move in the survey area, the operating screen 3 is used to operate the survey equipment, the signal receiver 2 is used to receive survey signals, and the roller 4 is used to assist the survey equipment to move to a suitable position. The surveyor keeps the horizontal height unchanged when holding the survey device, and relies on the cooperation of the stabilizing device and the roller 4 to record the height change between the surface and the main pole 1 to survey terrain data.

[0027] Furthermore, the surveyor's hand cannot maintain a constant horizontal height for a long time when continuously holding. In this case, errors will occur if the height change is only recorded by the stabilizing device and the roller 4. For this reason, an adjusting groove 6 is radially opened on the side wall of the main rod 1 and passes through the main rod 1. The handle 5 is a hollow sleeve and a connecting block 7 is radially fixedly installed on the inner wall of the handle 5. The connecting block 7 passes through the adjusting groove 6 and can slide up and down in the adjusting groove 6. Therefore, the handle 5 can also slide up and down along the main rod 1. A holding detection device is provided between the connecting block 7 and the end face of the adjusting groove 6. The holding detection device can detect the displacement of the relative sliding between the handle 5 and the main rod 1. In this embodiment, the holding detection device is composed of a first spring 8 and a first pressure sensor 9. The first spring 8 is an elastic spring, and the first pressure sensor 9 is a disc-shaped pressure detector. The first spring 8, the first pressure sensor 9 and the main rod 1 are coaxial.

[0028] In one embodiment, the gripping detection device is arranged on the lower end surface of the connecting block 7, and the upper end surface of the connecting block 7 is fitted with the top of the adjusting slide groove 6. When encountering undulating ground or horizontal ground, when the surveyor's grip level is fixed, the value detected by the first pressure sensor 9 is fixed. At this time, the roller 4 can also generate corresponding survey data at any time according to the surface undulation. When the ground is horizontal and the surveyor's grip level slowly decreases due to fatigue, the roller 4 supports the main rod 1 at the bottom, and the hand drives the handle 5 to slide down to press the first pressure sensor 9. After the first pressure sensor 9 detects the pressure change, it indicates that the surveyor can no longer keep the horizontal height of the surveying equipment unchanged. When encountering undulating ground and the surveyor's grip level slowly decreases due to fatigue, the pressure on the first pressure sensor 9 will gradually increase, thereby reminding the surveyor or compensating for the survey error through an algorithm.

[0029] A cavity 10 is provided on the bottom end surface of the main rod 1, and a stabilizing device is arranged in the cavity 10. The stabilizing device includes a sliding rod 11, a stabilizing spring 12 and a stabilizing pressure sensor 13. The sliding rod 11 can slide up and down in the cavity 10, and the roller 4 is fixedly installed at the bottom of the sliding rod 11. The stabilizing pressure sensor 13 is fixedly installed on the top of the stabilizing pressure sensor 13. The stabilizing pressure sensor 13 can also be fixedly installed on the top of the main rod 1. The stabilizing spring 12 is fixedly installed between the top of the cavity 10 and the top of the sliding rod 11. The height of the roller 4 relative to the ground is measured by the elastic force of the stabilizing spring 12 and the pressure exerted on the stabilizing pressure sensor 13. The stiffness coefficient of the first spring 8 is five times that of the stabilizing spring 12.

[0030] Furthermore, in order to facilitate wiring, the first pressure sensor 9 , the stable pressure sensor 13 and the second pressure sensor 15 are all fixedly mounted on the main rod 1 .

[0031] Furthermore, the inner diameter of the handle 5 is the same as the diameter of the main rod 1 , thereby reducing the shaking of the handle 5 when sliding up and down on the main rod 1 .

[0032] Furthermore, the outer wall surface of the grip 5 is provided with a rubber layer to improve the grip comfort of the surveyor.

[0033] Furthermore, the upper and lower ends of the handle 5 protrude outward to form a baffle, which can prevent the surveying equipment from slipping.

[0034] In another embodiment, Figure 4 As shown, the upper and lower ends of the connecting block 7 are provided with a gripping detection device, and the gripping detection device located above the connecting block 7 is composed of a second spring 14 and a second pressure sensor 15. At the same time, the second spring 14 has the same stiffness coefficient as the first spring 8. In this embodiment, the second pressure sensor 15 is fixedly mounted on the upper end surface of the adjusting slot 6, and the second spring 14 is fixedly mounted on the upper end surface of the connecting block 7. During the survey, the second spring 14 forms a balance with the first spring 8. When the second spring 14 exists between the connecting block 7 and the main rod 1, the main rod 1 can be lowered, providing two sets of data for simultaneous monitoring to reduce possible errors when the equipment is damaged.

[0035] Working principle of the utility model: Existing surveying equipment requires surveyors to hold the main pole 1 to keep the main pole 1 at a fixed horizontal height, and measure the distance between the bottom of the main pole 1 and the undulating ground through other means to conduct road surface survey. However, surveyors may not be able to maintain a fixed horizontal height due to fatigue when working. The utility model sets the main pole 1 and the handle 5 as a sliding connection, and sets a holding detection device composed of a first spring 8 and a first pressure sensor 9 at the connection. It can continuously monitor the pressure condition of the connection between the handle 5 and the main pole 1, and provide data for subsequent pressure change feature comparison. When the characteristics of the pressure change meet the characteristics of the horizontal height drop caused by fatigue, the surveyor is reminded, or the error caused by this is compensated by an algorithm, thereby improving the survey effect and accuracy.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
