Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a project cost surveying and mapping equipment. Background Art

[0002] The project cost is the construction price of the construction project. It is calculated based on the drawings, quotas and list specifications, including the direct costs, enterprise management fees, measures fees, fees, profits and taxes included in the project. When calculating the cost of the construction project, it is necessary to use construction engineering surveying and mapping instruments to survey and calculate the construction project, so as to make an estimate of the construction project cost in combination with the construction drawings.

[0003] After searching, the invention patent with Chinese patent number CN114111733A discloses a construction project cost on-site surveying and mapping device. Compared with the prior art, the invention patent with Chinese patent number CN114111733A sets a support frame and equipment legs, and the limit holes set inside the equipment legs are engaged with the threaded rods. When the threaded rod rotates counterclockwise, the threaded rod and the limit holes are loosened, and the support frame and the equipment legs can adjust the position of the equipment legs up and down through the equipment pad slider in the equipment slide groove opened inside the support frame, and adjust on the ground with different flatness, and then rotate the threaded rod clockwise, the threaded rod is engaged with the limit holes, thereby fixing the equipment legs and no longer sliding, so that the equipment can always remain in a vertical state on different grounds, so that the equipment can adapt to the ground with different flatness, which is convenient for the staff to use.

[0004] However, in actual use of the above-mentioned device, the design of the device mainly relies on the sliding of the equipment legs inside the support frame and the fixation of the threaded rod to achieve the vertical state of the equipment. However, this design does not take into account the possibility of the equipment legs entering below the surface for stabilization. On soft soil or loose ground, relying solely on the contact between the equipment legs and the ground may not provide sufficient stability. Especially in strong winds or uneven ground, the equipment still has the risk of tipping over. When the equipment legs need to be folded for carrying or storage, if the threaded rod is not turned clockwise in time to engage with the limit hole, the equipment legs may slide freely in the equipment slide slot or even fall off accidentally, which will not only affect the stability and safety of the equipment, but may also cause damage to the equipment legs. Therefore, it is necessary to propose an engineering cost surveying and mapping equipment. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the vertical state of the equipment is maintained mainly by relying on the sliding of the equipment legs inside the support frame and the fixation of the threaded rods.
