Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to an excavation device based on a BIM platform and a construction method. BACKGROUND

[0002] At present, BIM (Building Information Modeling) has been gradually applied to the field of building construction. By constructing a three-dimensional model of a building in a BIM platform, a building construction scheme can be obtained, which greatly improves the information integration level of building engineering and improves construction efficiency.

[0003] In related technologies, in the pile hole excavation construction process based on the BIM platform, a rotary drilling machine (i.e., an excavation device for pile holes) is usually used for excavation. The rotary drilling machine mainly includes a machine body and a support frame arranged on the machine body. A drill rod for drilling is arranged on the support frame in a liftable manner. A spiral blade is arranged on the side wall of the drill rod. When excavating a pile hole, the machine body is driven to move so that the drill rod on the support frame reaches the pile position. The drill rod is driven to rotate and to descend relative to the ground, so that the drill rod drills the pile position. When drilling to a certain depth, the spiral blade is used to transport the soil in the pile hole to a soil unloading position. The soil carried on the spiral blade is caused to fall by driving the drill rod to rotate. This process is repeated until the design hole depth is reached.

[0004] However, in the related art, when the rotary drilling machine drills a hole, some viscous soil adheres to the surface of the spiral blade during the transportation of the soil in the pile hole, and is not easy to fall off. If not cleaned in time, the soil adhering to the spiral blade will increase, resulting in low drilling efficiency. SUMMARY

[0025] The second object of the present application is to provide a construction method of an excavation device based on a BIM platform.

[0026] The construction method of the excavation device based on the BIM platform provided by the present application adopts the following scheme:

[0027] The construction method of the excavation device based on the BIM platform comprises,

[0028] S1, during drilling, the machine body is driven to move, so that the drill rod moves to the pile hole position where drilling is needed;

[0029] S2, the drill rod is driven to rotate and descend relative to the ground, so that the drill rod drills the pile hole, and the first motor is driven to rotate, so that the first half cover and the second half cover move towards each other, so that the first half cover and the second half cover are combined on the outer periphery of the drill rod;

[0032] In summary, the present application has at least one of the following beneficial technical effects:

[0033] 1. When it is necessary to clean the mud adhering to the spiral blades, this application drives the first motor to rotate, causing the sliding seat to move closer to the drill rod, so that the scraper abuts against the surface of the spiral blades. Under the elastic force of the first spring, the abutting block can continuously press against the surface of the spiral blades. At this time, the drill rod is driven to rotate and rise and fall relative to the ground, so that the scraper can clean the mud on the spiral blades more thoroughly. The cleaning effect of the scraper is better, thereby improving the drilling efficiency of the drill rod.

[0034] 2. This application utilizes a pair of meshing bevel gear sets mounted on the lead screw and the double-acting lead screw. When the first motor rotates, it drives the lead screw and the double-acting lead screw to rotate synchronously. This causes the first half-cover and the second half-cover to move towards each other to cover the outer periphery of the drill rod. At the same time, the sliding seat moves away from the drill rod, causing the scraper to retract into the fixed seat. Conversely, when the first half-cover and the second half-cover are driven to move away from each other, the sliding seat can move towards the drill rod, allowing the scraper to abut against the surface of the spiral blade. Furthermore, the first motor is the driving source for both the lead screw and the double-acting lead screw, thus saving production costs. Attached Figure Description
