Description
Technical Field
The utility model relates to the technical field of pile foundation construction, in particular to a drilling machine with an automatic drill rod adding function.
Background
The pile driver is a complex set of machine, and is composed of machine, machine set and mechanism. Different stake machines have different application scenarios. The pile machine is to utilize drilling tool to enter soil body, spray curing agent and mix with in situ soil body to form pile. Common drilling machines comprise single shafts, double shafts, three shafts, five shafts and the like, and the pile frame has large volume and the height is more than 30m. For piles with the construction diameter of more than 30m, the drill rods are connected in an additional mode to realize further deep layers. With the development of technology, methods for joining drill pipes are also gradually developed.
Chinese patent No. CN1000543265C describes the most traditional method of joining drill rods, (1) vertically placing the drill rods to be joined into a preformed hole located below ground, wherein the drill rod joint is located above ground; (2) Starting the construction of the pile, drilling the machine drill rod into the ground to a certain depth, and stopping drilling, wherein the drill rod joint is positioned above the ground; (3) Disassembling the drill rod joint, and keeping the drill rod at the position below the joint on the working pile position to be motionless, wherein the drill rod at the position above the joint moves along with the pile machine; (4) The pile machine drives the drill rod above the joint to move to the position of the drill rod to be connected, and the drill rod above the joint is fixedly connected with the top end of the drill rod to be connected to form an lengthened drill rod; (5) And the pile machine moves the lengthened drill rod to the working pile position, connects and fixes the drill rod at the position below the joint at the position with the bottom end of the lengthened drill rod, and then continues construction. With the development of mechanization and automation, the process is not used any more.
The Chinese patent No. 104481431B describes a drilling machine connecting drill rod mechanism, firstly, starting the drilling machine to enable a drilling machine mast to be vertical to the ground, pulling a fixed pin to enable a part of the mechanism, which is externally connected with the drill rod, to be approximately horizontal to the ground, moving the drill rod to be blocked by a stop block along the opening direction of a clamping opening of a clamping assembly, pulling a pin to adjust the size of the clamping opening of the clamping assembly, enabling the clamping assembly to hold the drill rod, inserting the clamping assembly into the clamping assembly to be locked by the pin, moving the pulling pin to enable the drill rod to be parallel to the mast, inserting the fixed pin to enable a rotary support to be fixed on a rotary seat frame, pulling a quick pulling pin, rotating a rotary arm to enable the drill rod to be moved to the rotary center of a power head, rotating the power head to screw the drill rod, pulling the pin to be separated from the clamping assembly, inserting the quick pulling pin to complete the assembly function of the drill rod, and reversely operating the drill rod according to the steps. The mechanism uses the mechanical gripper to pick up the drill rod on the ground, then completes the butt joint of the drill rod in a manual mechanical mode, is suitable for equipment such as a jumbolter with smaller drill rod, is not suitable for equipment with longer drill rod, firstly, the length of a single section of drill rod basically exceeds ten meters, the mechanical gripper cannot move as long as possible, and secondly, the mechanical gripper with larger weight of the drill rod is difficult to realize the grabbing action.
The Chinese patent No. 205689147U discloses an automatic drill rod connecting and discharging mechanism applied to drilling engineering, wherein a drill rod cabin is arranged on the side face of a stand column, and a manipulator is combined to cooperatively carry out automatic connection and discharging of a drill rod, and an upper assembly can be driven to move or rotate at least in the horizontal direction relative to the stand column through a swinging arm adjusting mechanism, so that the drill rod is connected. However, this construction is only suitable for use in small equipment such as jumbolters and the drill rods are threaded. The drill rod of the existing drilling machine is thick and long, has large weight, is a multi-channel drill rod and cannot be connected by threads. This means that the quick connect rod cannot be achieved using the above-described techniques and similar concepts.
In summary, in different application scenarios, the drill and the drill rod have large type selection differences, so that the mechanisms for connecting the drill rods are obviously different. The connecting rod designed at present is mostly used for small drill rods matched with the jumbolter, and has no obvious technical improvement on the connecting rod on the jumbolter. The applicant provides equipment for adding a connecting rod in 2019, and the equipment solves the problem to a certain extent, but the efficiency is still not high enough, so that the utility model provides a drilling machine with an automatic connecting drill rod, and the equipment can solve the problem that the long and heavy drill rods are not suitable for connecting through an automatic machine.
