Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation drilling machines, in particular to a fixing frame of a pile foundation drilling machine. Background Art

[0002] Before making the pile foundation, it is necessary to drill the pile foundation holes in advance. The pile foundation holes are usually completed by a pile foundation drilling machine. In order to facilitate the pile foundation drilling machine to perform the drilling work, a fixed frame is required to assist it in its work. The pile foundation drilling machine is installed on the fixed frame, and then the fixed frame drives the pile foundation drilling machine to rise and fall, and then the pile foundation drilling machine realizes the drilling of the pile foundation pit.

[0003] The existing fixing frame usually only serves the purpose of installing and lifting the pile foundation drilling machine, but lacks the function of effectively cleaning the drill rod of the pile foundation drilling machine. After the pile foundation drilling machine completes the drilling of the pile foundation and the drill rod moves out of the pile foundation pit, a large amount of mud will be stuffed between the spiral blades on the drill rod. Subsequently, personnel need to manually clean the mud stuffed between the spiral blades, which is very troublesome. In view of this, we propose a fixing frame for the pile foundation drilling machine. Utility Model Content

The front side of the shovel plate is the shovel end. The cross-section of the inner hole of the shovel plate is semicircular, and the thickness of the shovel plate decreases from back to front.

[0008] Preferably, the inner hole diameter of the shovel plate is the same as the drill rod diameter of the pile foundation drilling machine, and the height of the shovel plate matches the gap between the spiral blades on the drill rod of the pile foundation drilling machine.

The first hydraulic cylinders are arranged on the two groups of vertical rods on one side of the fixed bracket. The side plate is longitudinally arranged between the piston ends of the two groups of first hydraulic cylinders. The second hydraulic cylinder is arranged in the center of one side of the side plate, and the piston end of the second hydraulic cylinder is connected to the shovel plate.

[0010] Preferably, a docking plate is arranged on the rear side of the shovel plate, and the docking plate is fixedly docked with the piston end of the second hydraulic cylinder.

[0011] Preferably, the lifting structure includes a servo motor and a screw rod, the servo motor is arranged on the top of the fixed bracket, the screw rod is vertically arranged on the rotating shaft of the output end of the servo motor, and the screw rod passes through the mounting plate in the form of threaded fitting.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is provided with a cleaning structure. When the pile foundation drilling machine completes drilling the pile foundation hole, the shovel plate is adjusted up and down and left and right through the adjustment structure on the cleaning structure, so that the shovel plate is extended into the gap between the spiral blades of the drill rod of the pile foundation drilling machine. Then, when the drill rod rises and leaves the pile foundation hole, the drill rod is controlled to rotate continuously. At this time, the shovel plate can directly shovel away the soil stuck in the gap between the spiral blades of the drill rod, and complete the cleaning of the soil on the drill rod. There is no need for manual cleaning by personnel, which improves the convenience of use of the device. The utility model has the advantage of automatically cleaning the soil stuck between the spiral blades of the drill rod on the pile foundation drilling machine.

The shovel plate of the utility model is a semi-spiral structure, the front side of the shovel plate is the shovel end, and the thickness of the shovel plate decreases from the back to the front, and the cross-section of the inner hole of the shovel plate is semicircular. Therefore, when cleaning the soil stuck in the gap between the spiral blades of the drill rod on the pile foundation drilling machine, the inner hole of the shovel plate can fit the surface of the drill rod, and then when the drill rod rises and rotates, the front end of the shovel plate can fit the surface of the drill rod to perform shoveling work, and the shoveled soil will directly break away from the spiral blades and then fall off under the action of the gradually thickening outer side of the shovel plate. Therefore, the shovel plate has a better and more thorough cleaning effect on the soil in the gap between the spiral blades of the drill rod of the pile foundation drilling machine.
