Description

Technical Field

[0001] This utility model relates to the field of municipal engineering surveying technology, and in particular to a surveying device for municipal engineering management. Background Technology

[0002] Measurement devices for municipal engineering management are key tools throughout the entire lifecycle of municipal engineering projects. From the initial planning and precise implementation of construction to continuous management and maintenance, each stage relies on their support, greatly improving the work efficiency of staff and providing a solid guarantee for the smooth progress of municipal engineering projects.

[0003] In current municipal engineering operations, most surveying work is carried out by pulling lines on the ground. Operators need to maintain a squatting posture for a long time, which not only puts a lot of pressure on their bodies, but also greatly increases their workload due to the repetitive squatting and standing movements during long-term and large-area surveying tasks. This leads to low work efficiency and is also prone to physical fatigue and injury. This needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, where most measurement work is conducted by pulling wires on the ground. This requires operators to maintain a squatting posture for extended periods, which not only puts significant pressure on their bodies but also greatly increases their workload during long-term, large-area measurement tasks due to the repetitive squatting and standing movements, leading to low work efficiency and increasing the risk of fatigue and injury. Therefore, this invention proposes a measuring device for municipal engineering management.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a measuring device for municipal engineering management, comprising a base, rollers rotatably connected to the inner wall of the base, a measuring mechanism provided on the upper surface of the base, the measuring mechanism including a positioning rod, the positioning rod being fixedly connected to the upper surface of the base, a screw rotatably connected to the upper surface of the base, a mounting seat threaded onto the screw, one side of the mounting seat sliding against the surface of the positioning rod, two symmetrically arranged measuring rods rotatably connected to the inner wall of the mounting seat, guide wheels fixedly connected to the surfaces of both measuring rods, a support rod fixedly connected to the surface of one measuring rod, and a guide wheel fixedly connected to the surface of the other measuring rod. The device includes a positioning base, on the surface of which a measuring tape body is fixedly connected. The measuring tape body contains a measuring tape strip, one end of which is fixedly connected to the surface of a support rod. An auxiliary mechanism is provided on the surface of the positioning rod. A drive motor rotates a screw, automatically adjusting the height of the mounting base and controlling the opening and closing states of the two measuring rods. This eliminates the need for significant manual adjustments to the measuring rods, saving preparation time and improving work efficiency. Furthermore, the adjustable measuring mechanism eliminates the need for workers to maintain a squatting posture for extended periods, greatly reducing physical burden, fatigue, and the probability of injury from prolonged squatting – a testament to its user-friendly design.

[0006] Preferably, a clamp is fixedly connected to the surface of the positioning rod, and a drive motor is installed inside the clamp. The drive end of the drive motor is fixedly connected to the shaft of the screw.

[0007] Preferably, the base has a groove on its surface, through which the measuring tape passes to prevent wear on the measuring tape.

[0008] Preferably, a guide roller is rotatably connected to the surface of the measuring rod on the right side, and the measuring tape rests on the surface of the guide roller. During the measurement process, the measuring tape body and the guide roller cooperate with each other to ensure that the measuring tape is always taut. This not only facilitates reading and ensures the accuracy of the measurement data, but also avoids measurement errors caused by the slack of the measuring tape, thereby improving the accuracy and reliability of the measurement.

[0009] Preferably, the number of rollers is four, and the four rollers are arranged in a mirror image to facilitate stable support for the device.

[0010] Preferably, the auxiliary mechanism includes a connecting rod, which is fixedly connected to the upper surface of the positioning rod, and a handle is fixedly connected to the end of the connecting rod away from the positioning rod, so that pulling the handle can effectively move the equipment.

[0011] Preferably, the longitudinal section of the connecting rod is L-shaped.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, the drive motor rotates the screw to automatically adjust the height of the mounting base, thereby controlling the opening and closing states of the two measuring rods. This eliminates the need for manual adjustment of the measuring rods, saving measurement preparation time and improving work efficiency. Furthermore, the adjustable measuring mechanism of this device eliminates the need for workers to maintain a squatting posture for extended periods, greatly reducing the physical burden on workers, lowering the probability of fatigue and potential injuries caused by prolonged squatting, and embodying a human-centered design.

[0014] In this invention, during the measurement process, the measuring tape body and the guide roller cooperate with each other to ensure that the tape is always taut. This not only facilitates reading and ensures the accuracy of the measurement data, but also avoids measurement errors caused by tape slack, thus improving the accuracy and reliability of the measurement.

[0015] In this invention, the guide wheel on the measuring rod provides stable support for the measuring rod during the measurement process, reduces friction with the surface of the object being measured, makes the measuring rod move more smoothly, and further ensures the accuracy of the measurement data.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a measuring device for municipal engineering management, including a base 1, with rollers 2 rotatably connected to the inner wall of the base 1, and a measuring mechanism 3 provided on the upper surface of the base 1. The measuring mechanism 3 includes a positioning rod 31, which is fixedly connected to the upper surface of the base 1. A screw 312 is rotatably connected to the upper surface of the base 1, and a mounting seat 32 is threaded onto the screw 312. One side of the mounting seat 32 slides against the surface of the positioning rod 31. Two symmetrically arranged measuring rods 33 are rotatably connected to the inner wall of the mounting seat 32. Guide wheels 39 are fixedly connected to the surfaces of both measuring rods 33. A support rod 313 is fixedly connected to the surface of one measuring rod 33, and a positioning seat 310 is fixedly connected to the surface of the other measuring rod 33. The measuring tape body 38 is fixedly connected to the surface of the base 310. The measuring tape body 38 has a tape 311 inside. One end of the tape 311 is fixedly connected to the surface of the support rod 313. The surface of the positioning rod 31 is provided with an auxiliary mechanism 4. The drive motor 34 drives the screw 312 to rotate, realizing the automatic adjustment of the height of the mounting base 32, thereby controlling the opening and closing state of the two measuring rods 33. There is no need for manual adjustment of the measuring rods 33, saving measurement preparation time and improving work efficiency. Moreover, through the adjustable measuring mechanism 3, the device eliminates the need for workers to maintain a squatting posture for a long time, greatly reducing the physical burden on workers, reducing physical fatigue and the probability of physical injury caused by prolonged squatting, reflecting a humanized design.

[0024] In this embodiment: a clamp 35 is fixedly connected to the surface of the positioning rod 31, and a drive motor 34 is installed inside the clamp 35. The drive end of the drive motor 34 is fixedly connected to the shaft of the screw 312.

[0025] Specifically, the surface of the base 1 has a groove 36, through which the ruler 311 passes to avoid wear on the ruler 311.

[0026] In this embodiment, a guide roller 37 is rotatably connected to the surface of the measuring rod 33 on the right side, and the tape 311 rests on the surface of the guide roller 37. During the measurement process, the tape measure body 38 and the guide roller 37 cooperate with each other to ensure that the tape 311 is always taut. This not only facilitates reading and ensures the accuracy of the measurement data, but also avoids measurement errors caused by the slack of the tape 311, thus improving the accuracy and reliability of the measurement.

[0027] Specifically, there are four rollers 2, which are arranged in a mirror image to facilitate stable support for the device.

[0028] Specifically, the auxiliary mechanism 4 includes a connecting rod 41, which is fixedly connected to the upper surface of the positioning rod 31. A handle 42 is fixedly connected to the end of the connecting rod 41 away from the positioning rod 31. Pulling the handle 42 can effectively move the equipment.

[0029] Specifically, the longitudinal section of the connecting rod 41 is L-shaped.

[0030] Working principle: The operator can easily move the device to the designated measurement location by pushing it and using the rollers 2 to roll it on the ground. When performing the measurement, the drive motor 34 is turned on, causing the screw 312 to rotate. The mounting base 32 then moves downwards, pressing the two measuring rods 33. Supported by the guide wheels 39, the two measuring rods 33 then spread out to the sides. The support rod 313 then pulls the measuring tape 311 out of the measuring tape body 38. After the two guide wheels 39 have moved to the designated position, the drive motor 34 is turned off. Pulling the handle 42 allows for fine-tuning of the device. After observing the scale 311 on the guide roller 37, the measurement can be completed quickly. When measuring the next set of data, simply control the drive motor 34 to drive the screw 312 to rotate, and adjust the height of the mounting base 32 to adjust the state of the two measuring rods 33. During this process, the tape measure body 38, in conjunction with the guide roller 37, always ensures that the tape 311 is taut, which is convenient for reading. After the measurement is completed, control the drive motor 34 to drive the mounting base 32 to reset through the screw 312. This solution effectively improves the existing measurement method, reduces the need for workers to squat for long periods of time, and reduces the probability of physical fatigue and damage to workers.
