Rotating drilling rig enabling soil-discharging push plate to be automatically reset and construction method thereof

Abstract

The invention discloses a rotating drilling rig enabling a soil-discharging push plate to be automatically reset and a construction method thereof. A push and press device (5) is installed on a connecting disc (2) and comprises a push rod (12) and a pressing block (13), the pressing block (13) is provided with a guiding inclined plane (20) and a hook inclined plane (19), the push plate (18) is provided with a clamping seat (16), a clamping hook (14) is hinged to the clamping seat (16) through a hinge (15), and a barrel body (9) is provided with a positioning inclined block (17) which is provided with a positioning inclined plane (21). The clamping hook (14) is provided with a straight rod (22) corresponding positioned with the positioning inclined plane (21), a hook rod (23) correspondingly hooked with the hook inclined plane (19) and a convex surface (25) correspondingly pressed with the guiding inclined plane (20). After the push plate on a drilling bucket is utilized to discharge soil, the rotating drilling rig enables the drilling bucket to be reset to the top inside the barrel body of the drilling bucket so that the push plate has no influence on drilling, the influence on the push plate caused by the upward pushing force and rotating force of the soil in the barrel is reduced, and the reliability of the push plate is improved.

Description

technical field [0001] The present invention relates to a rotary drilling rig, in particular to a rotary drilling rig with automatic reset of the soil unloading push plate, and also relates to a construction method of the rotary drilling rig with automatic reset of the soil unloading push plate. Background technique [0002] The construction of the multi-functional rotary drilling rig is to use the drilling bucket to drill, and the ordinary drilling bucket ( figure 1 ) has a bucket door at the bottom, and there are cutting teeth on the bucket door, which are used to cut soil. The middle of the drill bucket is a hollow drill barrel, which accommodates the soil cut by the cutting teeth. Device for opening the bucket door. When working, the drilling rig lowers the hollow drill bucket to the drilling surface on the ground through the drill pipe; the power head of the drilling rig drives the drill bucket to rotate and advance in the hole through the drill pipe; during the drilli...

Problems solved by technology

Some have a return spring mechanism in the ejector rod, but due to the limited space on the drill bucket, the return spring force is difficult to meet the requirements of the complete reset of the push plate, so when returning to the position, part of the stroke needs to rely on the drill bucket to drill into the cylinder. The upward force of the soil returns to its position, so this upward force increases the drilling resistance, and because the bulldozing plate also bears the rotational friction of the soil while bearing the upward force of the soil, if the ejector rod extends into the barrel If it is long, the rotating force can twist the ejector rod and cause the hairpin to fail to work, so the reliability of the mechanism is poor.
