Abstract
Description
Technical Field
[0001] This utility model relates to the field of building surveying, and in particular to a surveying device for building engineering. Background Technology
[0002] In the field of construction engineering, the accuracy and stability of surveying equipment such as total stations, levels, and laser rangefinders directly affect the construction quality and efficiency. As the core support structure of surveying equipment, the tripod must be designed to meet requirements such as rapid deployment, stable adaptation to complex terrain, and resistance to external interference. However, the application of traditional tripods in complex construction environments still has significant limitations, specifically manifested in the following technical pain points.
[0003] Traditional tripods typically have legs of fixed length or only coarse adjustment. In scenarios with steep slopes, uneven ground, or obstacles such as foundation pits, mountains, and bridge construction, horizontal stability must be achieved by manually placing blocks, repeatedly moving the tripod, or adjusting the leg angles. This process is time-consuming and labor-intensive, and it is difficult to ensure uniform stress on the support surface, which can easily lead to tilting or settling of the measuring equipment, affecting measurement accuracy. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a measuring device for building engineering.
[0005] The measuring device for building engineering provided by this utility model adopts the following technical solution:
[0006] A measuring device for construction engineering includes a fixed platform, legs, and a support assembly. Three legs are provided, each hinged to the bottom of the fixed platform. The bottom of each leg is force-limitingly hinged to the support assembly. The support assembly includes a connecting plate, a connecting shaft, and a three-jaw support base. A connecting groove is formed at the bottom of each leg, and the connecting plate is force-limitingly hinged within the connecting groove. The bottom of the connecting plate is fixedly connected to the connecting shaft, and the bottom of the connecting shaft is connected to the three-jaw support base.
[0007] Preferably, the three-claw support base is provided with a ring array of connecting rod 1 and connecting rod 2. The connecting rod 2 is configured as an "L" shape. One end of the connecting rod 1 is hinged to the three-claw support base, the other end of the connecting rod 1 is hinged to the end of the connecting rod 2, and the center of the connecting rod 2 is hinged to the end of the three-claw support base.
[0008] Preferably, the three-claw support is provided with a three-claw connector, and one end of the connecting rod is hinged to the three-claw connector.
[0009] Preferably, the support leg includes a sleeve, an electric cylinder, and a telescopic leg. The electric cylinder is disposed inside the sleeve, and the output end of the electric cylinder is connected to the telescopic leg. The telescopic leg is slidably engaged with the sleeve.
[0010] Preferably, a fixing rod is connected to the bottom of the fixing platform, and a screw is fixed to the bottom of the fixing rod. A screw sleeve, a connecting sleeve, and a limiting rod are provided on the screw. The screw sleeve is threadedly connected to the screw, the connecting sleeve is rotatably connected to the outer wall of the screw sleeve, one end of the limiting rod is hinged to the outer wall of the connecting sleeve, and the other end of the limiting rod is hinged to the sleeve.
[0011] Preferably, both the connecting sleeve and the sleeve are provided with fixing components, and the two ends of the limiting rod are respectively hinged to the fixing components.
[0012] In summary, this utility model has at least one of the following beneficial technical effects:
[0013] 1. The connecting groove and connecting plate at the bottom of the outrigger adopt a force-limiting hinge, which can provide controllable support force in complex terrain. The three-claw support seat at the bottom of the connecting shaft adopts a ring array layout, which disperses the load pressure through three-point support and improves the stability of the equipment on soft soil or uneven ground. The first connecting rod is hinged to the three-claw support seat, and the other end is hinged to the second L-shaped connecting rod, forming a parallelogram linkage mechanism, which can adaptively adjust the support angle and maintain the horizontal reference. Combined with the outrigger adjustment function, it can quickly adapt to complex ground such as slopes and potholes.
[0014] 2. The electric cylinder is built into the sleeve, forming a closed drive chamber, which can effectively protect the electric cylinder from external dust, moisture and other corrosion, extend its service life, and achieve the effect of flexibly adjusting the support distance of the outriggers.
[0015] 3. The opening or tightening of the support legs needs to be adjusted by rotating the threaded sleeve. Tightening the threaded sleeve makes the connecting sleeve move in the vertical direction. Due to the constraint of the limiting rod, the opening or retraction angle of the three sets of sleeves is always the same, which greatly improves stability. Attached Figure Description

The three-jaw support seat 33 at the bottom of the connecting shaft 32 adopts a ring array layout, which disperses the load pressure through three-point support and improves the stability of the equipment on soft soil or uneven ground. Connecting rod 1 34 is hinged to three-jaw support seat 33, and the other end is hinged to L-shaped connecting rod 2 35 to form a parallelogram linkage mechanism, which can adaptively adjust the support angle and maintain the horizontal reference. Combined with the adjustment function of the support leg 2, it can quickly adapt to complex ground such as slopes and pits.
