The existing mapping equipment generally has the following defects: 1) the size of the volume of the surveying and mapping equipment is difficult to adjust according to different requirements, so that the use is not convenient enough; 2) the lower end of the triangular support frame is supported by 3 support legs, the lower ends of the support legs are pointed ends, when the triangular support frame is used on soft soil, the support legs can be inserted into the soil and are stably fixed, but when the triangular support frame is used on smooth and hard ground, the triangular support frame is easy to support unstably. 3) When in transportation, the feet with the pointed lower ends are easy to prick people.

Disclosure of Invention

The invention aims to provide a BIM-based engineering cost on-site construction auxiliary device to solve the problem that the volume and the form of the conventional mapping device are difficult to adjust according to the use requirement.

In order to achieve the purpose, the scheme of the invention is as follows: the utility model provides an engineering cost site operation auxiliary device based on BIM, includes the supporting part and establishes the surveying instrument body on the supporting part, its characterized in that: the supporting part comprises a bottom plate, a supporting plate positioned above the bottom plate and at least 3 telescopic connecting columns, wherein one end of each connecting column is hinged to the bottom plate, and the other end of each connecting column is hinged to the supporting plate; at least 3 fixed cylinders with openings at the upper ends are arranged on the bottom plate, pistons are connected in the fixed cylinders in a sliding mode, and inserting rods which can be located in the fixed cylinders and are pointed at the lower ends are arranged on the pistons; a sleeve communicated with the outside is fixed at the bottom of the fixed cylinder, and the inserted rod is connected with the sleeve in a sliding and sealing manner; a telescopic part is connected between the bottom plate and the support plate, and a cavity is formed inside the telescopic part; a plurality of channels are formed in the bottom plate, one ends of the channels are communicated with the cavity, the other ends of the channels are connected with the lower portion of the fixed cylinder, and when the telescopic portion is in a contraction state, the inserted rod is arranged in the fixed cylinder.

The working principle of the scheme is as follows:

when not needing to use auxiliary device, make the spliced pole shrink, the length of spliced pole shortens this moment, under the effect of spliced pole, the height of the surveying instrument main part in backup pad and the backup pad becomes short, and the holistic volume of auxiliary device diminishes, is more convenient for transport, accomodates. When the backup pad height became short, under the effect of backup pad, the pars contractilis contracts gradually, and the cavity volume in the pars contractilis diminishes, and in the gas in the pars contractilis passed through the lower part that the passageway got into a fixed section of thick bamboo, the inner wall upward movement of push pedal along a fixed section of thick bamboo under gaseous effect, the push pedal drives in the inserted bar shrink advances a fixed section of thick bamboo, makes the inserted bar arrange fixed section of thick bamboo in completely at last, can effectively avoid the inserted bar to hinder the people. When this auxiliary device is used to needs, tensile spliced pole makes the length of spliced pole lengthen, and under the effect of spliced pole, the height of the surveying instrument main part in backup pad and the backup pad promotes gradually. When the backup pad drove the surveying instrument main part and rises to the position that needs, stop tensile spliced pole, at this moment under the supporting role of spliced pole, surveying instrument main part in backup pad and the backup pad can remain stable state. At the ascending in-process of backup pad, the backup pad makes the pars contractilis extend gradually, cavity volume grow in the pars contractilis, gas in the solid fixed cylinder lower part passes through in the passageway shifts the pars contractilis gradually, at this moment, the inner wall downstream of push pedal along solid fixed cylinder, the inserted bar moves along with the push pedal together, the inserted bar inserts gradually in soil, ensure the firm degree that bottom plate and soil are connected, can effectively avoid auxiliary device to take place to remove in the use, ensure the stability that auxiliary device used.

The beneficial effect of this scheme lies in:

1. the auxiliary device can change the volume and the shape according to different requirements, when the auxiliary device needs to be stored or transported, the volume of the auxiliary device can be integrally reduced, and the auxiliary device is convenient to transport or store; and the inserted bar can be automatic to shrink in the fixed section of thick bamboo this moment, avoids the inserted bar to stretch out and injures people. When needs use auxiliary device to survey and draw, the accessible is tensile spliced pole makes the surveying instrument main part rise to suitable position, and meanwhile, the inserted bar can stretch out by the initiative downwards, and the inserted bar can insert in soil for the supporting part can stabilize effectual support surveying instrument main part.
