Description

Technical Field

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

[0002] Construction engineering surveying and setting out refers to the on-site measurement and setting out before the construction of a construction project. It is generally carried out using devices such as theodolites or total stations. Surveying and setting out devices are required during the measurement process to ensure the accuracy of the measurements.

[0003] In practical engineering applications, tripods are typically used as support platforms for theodolites / total stations. While their stability ensures normal instrument operation, significant operational bottlenecks remain in high-rise building construction. Specifically, axis projection between different floors requires vertical transfer of control points to ensure positioning accuracy at each floor. During this process, the instrument must be precisely aligned with the target point during setup, ensuring the infrared ranging ray coincides with the preset mark. However, traditional operations require repeated adjustments to the tripod position and relocation of the equipment. Due to the significant weight of the instrument and support structure, manual relocation is not only time-consuming and labor-intensive, but the frequent opening and closing of the instrument for coarse and fine adjustments significantly reduces spatial positioning efficiency. Utility Model Content

[0004] The purpose of this invention is to address significant operational bottlenecks in the construction of high-rise buildings using existing technologies. Specifically, axis projection between different floors requires vertical transfer of control points to ensure positioning accuracy at each floor. During this process, the instrument must be precisely aligned with the target point during setup, ensuring that the infrared ranging ray coincides with the preset mark. However, traditional operations require repeated adjustments to the tripod position and relocation of equipment. Due to the large overall mass of the instrument and support, manual relocation is not only time-consuming and labor-intensive, but the frequent opening and closing of the instrument for coarse and fine adjustments significantly reduces spatial positioning efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a surveying and setting-out device for construction engineering, comprising a mounting plate, three evenly distributed connecting frames fixedly connected to the outer periphery of the mounting plate, each connecting frame being provided with a support mechanism, an adjustment cavity being formed inside the mounting plate, a connecting seat being slidably connected inside the adjustment cavity, an adjustment seat being slidably connected to the top of the connecting seat, a connecting bolt being fixedly connected to the middle of the adjustment seat, a second adjustment screw being rotatably connected inside the adjustment cavity, the second adjustment screw being threadedly connected to the connecting seat, a T-shaped slider being fixedly connected to the end of the adjustment seat, a first adjustment screw being threadedly connected inside the adjustment cavity, a push plate being provided at the end of the first adjustment screw, and the push plate being threadedly connected to the first adjustment screw... A connecting cap is provided at the position of the first adjusting screw on the plate. The connecting cap is rotatably connected to the end of the first adjusting screw. The push plate has a groove that slides with the T-shaped slider. The bottom of the theodolite / total station is usually provided with a threaded hole to facilitate fixed connection with the tripod. The connecting bolt can be used with the theodolite / total station to achieve a fixed connection. The connecting seat can be moved linearly along the second adjusting screw by rotating the second adjusting screw. The adjusting seat can be slid on the connecting seat by rotating the first adjusting screw, so that the position of the instrument installed on the connecting bolt can be adjusted. There is no need to move the tripod during the adjustment process, which reduces the physical exertion of the operator during the movement and improves the spatial positioning efficiency during the use of the device.

[0006] In a preferred embodiment, the rear end of the push plate is fixedly connected to two symmetrically distributed guide rods, which are slidably connected to the mounting plate. The guide rods guide and limit the movement of the push plate.

[0007] In a preferred embodiment, a guide block is fixedly connected to the lower end of the adjusting seat, and a guide groove is provided at the top of the connecting seat. The guide block is slidably connected in the guide groove. The guide groove and the guide block can play a guiding and limiting role in the movement of the adjusting seat.

[0008] In a preferred embodiment, a sliding groove is provided in the adjustment cavity, and a sliding block is fixedly connected to the bottom end of the connecting seat. The sliding block is slidably connected inside the sliding groove, and the guide block, in cooperation with the sliding groove, can guide and limit the movement of the connecting seat.

[0009] In a preferred embodiment, a second adjusting handle is fixedly connected to the end of the second adjusting screw, and a first adjusting handle is fixedly connected to the end of the first adjusting screw. The first adjusting handle facilitates the rotation of the first adjusting handle and the second adjusting handle.

[0010] In a preferred embodiment, both the first and second adjusting handles are provided with uniformly distributed grooves on their outer peripheries, which can improve the contact friction between the first and second adjusting handles, making the rotation of the second and first adjusting handles easier.

[0011] In a preferred embodiment, the support mechanism includes a sliding sleeve fixedly connected to the end of the connecting block, and a support leg slidably connected inside the sliding sleeve. The bottom end of the support leg is tapered, and the support leg serves to support the device.

[0012] In a preferred embodiment, the lower end of the sliding sleeve is threaded with a locking bolt, which can be rotated to press the support leg inside the sliding sleeve, thereby achieving the function of limiting the position of the support leg.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention allows the connecting seat to move linearly along the second adjusting screw by rotating the second adjusting screw, and the adjusting seat to slide on the connecting seat by rotating the first adjusting screw. This allows for position adjustment of the instrument mounted on the connecting bolt. The adjustment process does not require moving the tripod, reducing the physical exertion of the operator during the movement process, and improving the spatial positioning efficiency of the device during use.
