Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering measurement, in particular to a construction engineering measurement device. Background Art

[0002] Earth excavation is a key process in the early stages of a construction project and throughout the construction process. It involves loosening, crushing, excavating, and transporting soil and rock. Based on the nature of the rock and soil, earth and rock excavation is divided into earth excavation and rock excavation. The depth of the earthwork is excavated according to the design requirements, so after the earthwork excavation is completed, tools are needed to measure the extent of the excavation.

[0003] The currently published patent: CN219794033U, discloses a foundation pit depth measuring device for foundation pit monitoring. By setting a support assembly and a measuring assembly, the worm is rotated by the turntable, so that the meshing worm wheel rotates, driving the rotating shaft and the winding drum to rotate, and driving the pull rope to pull the counterweight block to move under the support of the second pulley and the first pulley, thereby facilitating the winding of the winding ruler and achieving the purpose of facilitating the winding of the ruler.

[0004] Based on the above search, it was found that the above patent has the following problems when in use: when the foundation pit depth measuring device is used for measurement, the worm is rotated by the turntable, so that the meshing worm wheel rotates, driving the rotating shaft and the winding drum to rotate, driving the pull rope to pull the counterweight block to move for measurement under the support of the second pulley and the first pulley. This measurement method is similar to the manual measurement method with a ruler. Although it can ensure that the ruler is vertical, it can only measure the height of the foundation pit edge and cannot measure the position inside the foundation pit. The measurement range is relatively limited, which further affects the convenience of surveyors in measuring the depth of different positions of the foundation pit. Utility Model Content

The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] See also Figure 1-4The utility model provides a technical solution: a construction engineering measuring device, including a measuring trolley 1 and a depth measuring device, a rotating stick 2 is rotatably installed on the rear side of the measuring trolley 1, the right end of the rotating stick 2 is fixedly connected to a winding disk 3, a measuring rope 5 is wound inside the winding disk 3, and a turntable 4 is fixedly connected to the left end of the rotating stick 2. A fixed block 6 is fixedly connected to the front side of the measuring trolley 1, a support tube 7 is slidably sleeved inside the fixed block 6, the measuring rope 5 is slidably sleeved inside the support tube 7, and the front end of the measuring rope 5 is fixedly connected to a conical pendant 9. A bolt 8 is installed on the top of the fixed block 6, and the lower end of the bolt 8 contacts the surface of the support tube 7.

[0025] When the measuring device is in use, the staff first moves the measuring trolley to the edge of the foundation pit, then rotates the bolt 8 with a wrench to disengage it from the surface of the support tube 7, thereby releasing the fixing effect on the support tube 7. Then, the staff can slide the support tube 7 forward so that the front end of the support tube 7 moves to the position where the depth of the foundation pit needs to be measured, and then rotates the bolt 8 again with a wrench and squeezes it against the surface of the support tube 7 to fix it.

[0026] The depth measuring device includes a measuring wheel 10, a data display screen 11, a slide 12, a slider 13, a guide rod 14, a spring 15 and an upper pressure wheel 16. The measuring wheel 10 is rotatably installed inside the measuring trolley 1, and the surface of the measuring wheel 10 contacts the surface of the measuring rope 5. The data display screen 11 is fixedly installed on the top of the measuring trolley 1, the slide 12 is fixedly connected to the top of the measuring trolley 1, the slider 13 is slidably connected to the inside of the slide 12, the guide rod 14 is slidably sleeved on the inside of the slider 13, the guide rod 14 is fixedly connected to the inside of the slide 12, the spring 15 is slidably sleeved on the surface of the guide rod 14, the upper end of the spring 15 is fixedly connected to the top wall of the slide 12, and the lower end of the spring 15 is fixedly connected to the top of the slider 13. The surface of the slider 13 is rotatably connected to the upper pressure wheel 16, and the surface of the upper pressure wheel 16 contacts the surface of the measuring rope 5.

[0027] When the lifting rod 13 is lifted up, the lifting rod 13 is lifted up and the lifting rod 13 is lifted up, and the lifting rod 13 is in the downward direction, so that the lifting rod 13 can move downwards, thereby reducing the risk of accidental tampering.

[0028] After the staff slides the upper pressure wheel 16 upward by hand and separates it from the surface of the measuring rope 5, the staff can slide the support tube 7 backward and store it into the interior of the measuring trolley 1, reducing the overall length of the measuring device and making it easier for the staff to move the measuring device.

[0029] Working principle: For the construction engineering measuring device, the staff rotates the bolt 8 with a wrench and separates it from the surface of the support tube 7. The staff can slide the support tube 7 forward so that the front end of the support tube 7 moves to the position where the depth of the foundation pit needs to be measured. The staff can rotate the rotating rod 2 through the turntable 4 and drive the reel 3 to rotate and release the measuring rope 5. At this time, the conical pendant 9 slides downward due to its own gravity and drives the front end of the measuring rope 5 to gradually move downward. When the conical pendant 9 slides to contact the ground, it no longer pulls the measuring rope 5 to slide downward. During the movement of the measuring rope 5, the friction force can drive the measuring wheel 10 to rotate and measure the distance and display it on the data display screen 11. The distance measured by the measuring wheel 10 is the distance that the measuring rope 5 slides downward, which is the depth of the foundation pit. Not only can the height of the foundation pit edge be measured, but also the position inside the foundation pit can be measured through the supporting effect of the support tube 7.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
