Problems solved by technology

This new multi-functional high-precision engineering surveying and mapping tower ruler is set by a motor, a rotating shaft, a measuring rope and a tower ruler. During the process of underground measurement, the motor drives the rotating shaft to make the measuring rope descend. According to the descending height of the measuring rope, Then measure through the tower ruler, thereby increasing the measurement length of the tower ruler, but the operation of the support devices on the left and right sides of the device is relatively cumbersome, and it is also relatively cumbersome to fold, so the device needs to be improved

Embodiment 1

[0026] see figure 1 with figure 2 , a new type of multi-functional high-precision engineering surveying and mapping tower ruler, including a main body 1, the top of the main body 1 is provided with a bearing seat 32, the bearing seat 32 is rotatably connected to the left and right ends of the winding roller 27, and the upper right side of the main body 1 is provided with a drive Motor 28, the output shaft of drive motor 28 is fixedly connected first belt pulley 29, and first belt pulley 29 is connected second belt pulley 31 by belt 30, and second belt pulley 31 is fixedly connected the right end of winding roller 27, and winding roller 27 exteriors Hanging rope 33 is arranged, and the lower end of hanging rope 33 is provided with the 3rd fixed plate 23, and the bottom of the 3rd fixed plate 23 is provided with surveying head 25, and the middle part of the lower surface of main body 1 is provided with the relief hole 18, and the 3rd fixed plate 23 and Reinforcing ribs 24 are ...

Embodiment 2

[0029] see image 3 , the other content of this embodiment is the same as that of Embodiment 1, the difference is that: the left end of the winding roller 27 is provided with a rotating wheel 39, the side wall of the rotating wheel 39 is provided with a limiting hole 40, the upper left of the main body 1 The side sliding connection is connected with the limit rod 35 that is matched with the limit hole 40, and the top of the limit rod 35 is slidably connected to the fixed frame 2, and a second spring 38 is arranged between the fixed frame 2 and the top of the limit rod 35, and the front and back of the fixed frame 2 Top blocks 36 are arranged on both sides, and top plates 37 are arranged on the left and right sides of the limit rod 35 . Because the winding roller 27 of the device is driven by the drive motor 28, yet the drive motor 28 may break down, in order to prevent the surveying head 25 from falling, a limit rod 35 and a limit hole 40 are set on the left side of the device...

Abstract

The invention relates to the technical field of engineering surveying and mapping, and discloses a novel multifunctional high-precision engineering surveying and mapping box staff. The novel multifunctional high-precision engineering surveying and mapping box staff comprises a main body. The top of the main body is provided with bearing seats rotatably connected with the left and right ends of a winding roller, the exterior of the winding roller is provided with a lifting rope, the lower end of the lifting rope is provided with a third fixing plate, and the lower portion of the third fixing plate is provided with a surveying and mapping head. The middle portions of the left and right side walls of the main body are provided with avoidance grooves, the middle portions of the avoidance grooves are provided with rotating shafts, the middle portions of the rotating shafts are rotatably connected with the ends, close to the center of the device, of ejecting rods, and the ends, away from thecenter of the device, of the ejecting rods are rotatably connected with the lower portions of sliding sleeves. According to the novel multifunctional high-precision engineering surveying and mappingbox staff, first limiting grooves and second limiting grooves are formed in the upper portions of the sliding sleeves and connected with stop rods in a clamping manner respectively, so that the wholedevice is supported by the sliding sleeves and sliding rods when in use; and the sliding sleeves, the ejecting rods and supporting rods are completely retracted into the avoidance grooves on the leftand right sides when the device is retracted, so that the portability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a novel multifunctional and high-precision engineering surveying and mapping tower ruler. Background technique [0002] The tower ruler is a kind of leveling ruler. Most of the early leveling rods were made of wood, heavy and limited in length (generally 2m), and it was inconvenient to carry when measuring. Later, it is gradually made of aluminum alloy and other light-weight and high-strength materials. It adopts a tower-type shrinking form, which is convenient to pull out when in use, and the single-elevation measurement range is greatly improved. The length is generally 5m. Tower-shaped, so it is often called a tower ruler. [0003] When the tower ruler is used, it usually needs a hoisting device to realize long-distance surveying and mapping, and related equipment is needed at this time. [0004] Chinese patent (notification number: CN208704714U) d...
