Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically a grooving machine. Background Technology

[0002] A slotting machine is a specialized piece of machinery used in underground engineering projects such as mines and tunnels to cut rock walls, coal seams, or concrete. It is mainly used for trenching, cutting, and shaping of roadway contours, thereby facilitating roadway excavation, support construction, gas extraction, water trench excavation, and cable trench excavation. Mining slotting machines improve construction efficiency, reduce manual labor intensity, and are suitable for cutting hard rock, semi-coal rock, or soft rock. Based on the slotting method, slotting machines are mainly classified into: chain arm slotting machines, circular saw slotting machines, water jet slotting machines, and hydraulic splitting slotting machines.

[0003] Currently, slotting machines are based on hydraulic excavators used in coal mines, using hydraulic drive to rotate the cutting section for construction. Their advantage lies in their flexible movement. However, slotting machines mounted on conventional hydraulic excavators still have the following shortcomings during slotting operations:

[0004] 1. When the height of the tunnel is limited, the limited range of motion of the rocker arm prevents the cutting unit from performing grooving operations on the top and bottom plates of the tunnel wall.

[0005] 2. The low precision of manually controlling the movement of the rocker arm in hydraulic excavators leads to inconsistent slotting depths. Utility Model Content

[0006] In order to solve the technical problems existing in the background art, this utility model provides a grooving machine that can accurately groove the four sides of the tunnel wall.

[0007] The technical solution adopted by this utility model is:

[0008] A grooving machine, comprising:

[0009] The main rotating mechanism, extension mechanism, and auxiliary rotating mechanism are sequentially rotated and connected. The main rotating mechanism is supported and installed between the tunnel walls for fixation. The extension mechanism extends the auxiliary rotating mechanism to the working position. The auxiliary rotating mechanism drives and adjusts the grooving component to perform grooving operations at the working position.

[0010] Furthermore, the main rotating mechanism includes:

[0011] A frame-type foundation is placed on the bottom plate of the tunnel wall. Lifting cylinders are installed at the four corners of the foundation. The stroke ends of the lifting cylinders are upward-facing and extend to abut against the top plate of the tunnel wall. A secondary hinge lug and a main hinge lug extend upwards from the foundation. The main hinge lug is located in the middle of the foundation. A main rotating cantilever is hinged to the side wall of the main hinge lug. A main rotating crank arm is hinged to the end of the main rotating cantilever. The secondary hinge lug is located on one side of the main hinge lug, and a main rotating cylinder is hinged to the secondary hinge lug. The stroke end of the main rotating cylinder is hinged to the middle of the main rotating cantilever.

[0012] Furthermore, the secondary hinge lug, main hinge lug, main rotary cantilever, main rotary crank arm, and main rotary cylinder are symmetrically arranged in two sets;

[0013] The extension mechanism is located at the aforementioned symmetrical centerline.

[0014] Furthermore, the extension mechanism includes:

[0015] A rocker arm rotatably connected to a main hinge lug has a main hinge shaft and a drive hinge shaft at the middle of its outer wall. The main hinge shaft is hinged to the main hinge lug, and the drive hinge shaft is hinged to the end of a main rotating crank arm. An extension arm is movably inserted outside the rocker arm, and a hinge seat is provided at the end of the extension arm. A secondary rotating cantilever is hinged on the outer wall of the extension arm near the hinge seat, and a secondary rotating crank arm is hinged at the end of the secondary rotating cantilever. An extension cylinder is hinged between the rocker arm and the extension arm. An extension seat is provided radially at the middle of the extension arm, and a secondary rotating cylinder is hinged on the extension seat. The stroke end of the secondary rotating cylinder is hinged outside the rocker arm.

[0016] Furthermore, on the outer wall of the rocker arm, the main hinge shaft is disposed between the drive hinge main shaft and the hinge part of the extension cylinder.

[0017] Furthermore, the hinge portion of the extension cylinder on the outer wall of the extension arm is located on the outer wall of the rocker arm between the secondary rotating cantilever and the extension seat, and is positioned close to the secondary rotating cantilever.

[0018] Furthermore, two sets of the extension mechanism are symmetrically arranged;

[0019] The secondary rotating mechanism is located at the symmetrical centerline of the two sets of extension mechanisms.

[0020] Furthermore, the secondary rotating mechanism includes:

[0021] A base rotatably connected to a hinge seat has a secondary hinge shaft and a drive hinge secondary shaft on its outer wall. The secondary hinge shaft is hinged to the hinge seat, and the drive hinge secondary shaft is hinged to the end of a secondary rotating crank arm. An adjusting frame is movably inserted inside the base. A hydraulic motor is installed at the end of the adjusting frame. A rotating shaft is coaxially driven on the hydraulic motor. The rotating shaft passes through the adjusting frame and is coaxially driven by a cutting head. An adjusting cylinder is hinged between the base and the adjusting frame.

[0022] Furthermore, the secondary hinge shaft is located in the middle of the outer wall of the base;

[0023] The drive hinge sub-shaft is positioned away from the cutting head.

[0024] The beneficial effects of this grooving machine are as follows:

[0025] 1. The rocker arm rotates 360° through the main rotary drive assembly, thereby slotting the four sides of the tunnel wall.

[0026] 2. First, the extension mechanism controls the cutting head to extend to the working position; then, the secondary rotation mechanism adjusts the cutting head to achieve precise control of the cutting head. Attached Figure Description
