The technical result of the utility model is to increase the reliability of the connection of the rotator with the clamping device of the vibrator due to the use of an automatic safety device (clamps) located on the rotator, reducing the size, weight of the rotator and the complexity of its manufacture due to the use of a high-torque hydraulic motor, the use of a special opening rest, as well as the possibility of use of the drilling body on its own on a special bracket instead of a vibrator. This task is achieved by using advanced drilling equipment containing a rotator with a safety device, an auger with a drill and a mounting support, while the rotator is gearless, and a high-torque hydraulic motor is used as a drive hydraulic motor, the rotator is additionally equipped with threaded holes for fastening it in the clamping device of a vibrator or on a special bracket instead of a vibrator for prolonged use as directed. In addition, the equipment is equipped with a rest, permanently mounted on the mast of the machine in its lower part and made with the possibility to provide in the open position unhindered passage of the vibrator with a pile foundation during vibration immersion.

Description

This useful model of drilling equipment (hereinafter referred to as equipment) relates to construction equipment and is used for drilling wells before vibro-immersion of industrial piles and pile foundations of supports of the contact network of railways using machines such as AVF, MS.

The closest analogue of the claimed utility model, i.e. the prototype is a utility model "Equipment for drilling leading wells for AVF units and MS machines" (RU patent No. 95617, IPC B61D 15/00 (2006.01), published: 07/10/2010), containing a hydraulic power unit, control and monitoring means, loading equipment, slewing ring device, a guide frame placed on a slewing ring device, a carriage moving along the guide frame, a vibrator, mounted on the carriage, while the equipment is made in the form of a replaceable drill, which is fixed in vibration le. In addition, the drill is designed for drilling leading wells with a diameter of 360 or 630 mm, consists of a rotator, auger, adapter, cutter head, equipment, additionally contains a set of hydraulic equipment for connecting to AVF units and MC machines, the rotator consists of a two-stage gearbox and a hydraulic the motor, on the top of the gearbox, coaxially with the output shaft, a head is fixed, which serves to install and fix the rotator in the clamping device of the vibrator, the screw consists of a pipe, a spiral blade, the end output bushings with square holes for connection to the rotator and adapter, the design of the screw with a diameter of 350 mm is similar to the design of the screw 630 mm.

The disadvantages of the above utility model is the insufficiently reliable fixation of the rotator in the clamping device of the vibrator, the absence of a guide rest providing directional drilling and unloading the rotator bearings, as well as the increased dimensions of the rotator.

The objective of this utility model is to eliminate all of the listed disadvantages of this prototype.

The technical result of the utility model is to increase the reliability of the equipment through the use of a safety device (clips) located on the rotator, through the use of a high-torque hydraulic motor, the use of a special opening lunette, as well as the possibility of using the drilling body independently on a special bracket instead of a vibrator.

Additionally, the equipment is equipped with a mounting support that allows you to install it (and remove) in the clamping device of the vibrator from the table of the loading and charging device of the machine.

This task is achieved by using advanced drilling equipment containing a rotator with a safety device, an auger with a drill and a mounting support, while the rotator is gearless, and a high-torque hydraulic motor is used as a drive hydraulic motor, the rotator is additionally equipped with threaded holes for fastening it in the clamping device of a vibrator or on a special bracket instead of a vibrator for prolonged use as directed.

In addition, the equipment is equipped with a rest, permanently mounted on the mast of the machine in its lower part, and made with the possibility to provide in the open position unhindered passage of the vibrator with a pile foundation during vibration immersion.

This utility model is illustrated by drawings.

In FIG. 1 shows a General view in section of the drilling equipment and a top view.

Drilling equipment 1 (Fig. 1), comprising a rotator 2, a screw 3 with a drill 4, a mounting support (not specified), a safety device 5, which is mounted on the rotator 2.

The rotator is gearless, and a high-torque hydraulic motor is used as the driving hydraulic motor 6. In addition, the rotator 2 is additionally equipped with threaded holes 7 for fixing it in the clamping device of the vibrator 8 during prolonged use for its intended purpose or for fixing it on a special bracket. The drilling equipment is equipped with a rest (not shown), permanently mounted on the mast of the machine in its lower part, the rest is made with the ability to provide in the open position an unhindered passage of the vibrator with a pile foundation during vibration immersion.

The device operates as follows.

The equipment assembled and fixed on the mounting support, including the rotator 2, the screw 3 and the drill 4, with the help of a crane-manipulator of the machine is rearranged from the platform of the machine to the horizontal table of the loading and charging device and fixed on it. After that, the table rises to grab the equipment. The lunette on the mast is opened, the clamping device of the vibration absorber 8 is pushed onto the equipment rotator 2 until it stops and it is gripped. When the jaws of the clamping device are pressed on the lower parts of the safety devices (for example, clamps), the latter rotate, their upper parts protrude above the cheeks and prevent the rotator from falling out. (When the cheeks are pulled apart, the latches automatically take their initial position under the action of the springs and the rotator can be removed from the clamping device without hindrance.) The vibro-driver with drilling equipment rises to a distance within the mounting support, the latch shutters are closed, the table is lowered, and the vibro-driver with equipment is raised to its upper position. After that, the machine equipment is brought into working position and the leader well is drilled.

Drilling equipment is removed in the reverse order.

This device:

allows to combine leader drilling of wells and immersion of foundations in one technological cycle, which increases the productivity of the machine;

improves the quality of drilling operations and the subsequent installation of foundations through the use of a guide rest during drilling;

increases the safety of work due to the reliability of the connection of the vibrator with attachments using a safety device located on the rotator;

allows you to install it (capture) in the clamping device of the vibrator from the table of the loading and charging equipment of the machine;

Served by one person.
