Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine and tunnel mining machinery, specifically relating to an explosion-proof hydraulic excavation and repair integrated machine. Background Technology

[0002] With the development of economic construction, the mechanization and automation of the coal industry are constantly deepening. More and more manual operations in mining are being replaced by machinery, and work efficiency and safety have been greatly improved. However, some supporting auxiliary operations, such as tunnel bottom cleaning, drainage ditch excavation, and tunnel repair, have not yet been mechanized.

[0003] During coal mining, as the mining depth increases, the ground pressure also increases. During mining, the stress in the rock mass is redistributed and interacts with the external forces of the support equipment until a new equilibrium is reached. During this equilibrium process, the rock mass around the roadway will move, deform, and break down, resulting in phenomena such as floor heave and sidewall deformation. The roadway damage becomes more severe, causing the net cross-section and height of the mine roadway to fail to meet design requirements, creating many safety hazards and requiring timely roadway repair. In addition, the transportation and hoisting of spare parts and materials during the production of fully mechanized mining and tunneling equipment, as well as the cleaning of loose coal under the roadway and belt conveyor, are also tasks that urgently need to be mechanized to replace manual labor.

[0004] Due to the limitations of roadway support and equipment layout underground, the auxiliary operation space is small but the work is complex and requires a single machine to complete it. This requires the machinery to be compact and lightweight, flexible in operation, and to have multiple functions such as excavation, crushing, anchor bolt cutting, bottoming, slag removal, and contour trimming. Although the existing single models can achieve the above functions, they cannot accurately excavate the required contour of the roadway, and a lot of manual time is still needed for contour trimming. Summary of the Invention

[0005] This utility model provides an explosion-proof hydraulic excavation and repair integrated machine, which can not only crush, excavate, and load, but also realize the conversion of five functions such as "breaking, shoveling, loading, transporting, and anchor bolt cutting" in a short time, greatly reducing manual labor and truly realizing the mechanization of tunnel maintenance.

[0006] This utility model embodiment provides an explosion-proof hydraulic excavation and repair integrated machine, including a vehicle body mechanism, a tracked walking mechanism at the bottom of the vehicle body mechanism, a bulldozer blade mechanism at the bottom side of the outer side wall of the vehicle body mechanism, a canopy mechanism at the top of the vehicle body mechanism, and a boom cylinder and a boom mechanism at the side of the top of the vehicle body mechanism near the canopy mechanism. The output end of the boom cylinder is hinged to the boom mechanism, and the boom mechanism is hinged to the vehicle body mechanism.

[0007] A rear auxiliary middle arm is hinged to the boom mechanism, and a middle arm rear cylinder is provided on the outer wall of the boom mechanism. The output end of the middle arm rear cylinder is hinged to the rear auxiliary middle arm. A rotary reducer is provided on the rear auxiliary middle arm, and a front auxiliary middle arm is provided at the output end of the rotary reducer.

[0008] The front arm has a front arm cylinder and a stick mechanism hinged to its outer side wall. The output end of the front arm cylinder is hinged to the stick mechanism. The stick mechanism has a stick cylinder hinged to it. The output end of the stick cylinder is hinged to a rocker arm mechanism. The stick mechanism is equipped with a bucket or crushing mechanism. A linkage mechanism is provided between the rocker arm mechanism and the stick mechanism.

[0009] Furthermore, the boom mechanism, the rear auxiliary middle arm, the front auxiliary middle arm, and the stick mechanism form a four-section linkage boom. The four-section linkage boom includes: the boom mechanism and the boom cylinder that controls the boom mechanism, the rear auxiliary middle arm and the middle arm rear cylinder that controls the rear auxiliary middle arm, and the rotary reducer at the connection between the rear auxiliary middle arm and the front auxiliary middle arm.

[0010] Furthermore, a hydraulic shear mechanism is provided on the top of the vehicle body mechanism near the roof mechanism.

[0011] Furthermore, the vehicle body structure consists of a front control panel, main valve, fuel tank, rotary motor, diesel tank, water tank, explosion-proof engine pump assembly, counterweight, water tank, air tank, cooler, center joint, and headlights.

[0012] Furthermore, the roof mechanism is an adjustable structure, and the vehicle body mechanism is provided with three holes for adjusting the height of the roof mechanism.

[0013] Furthermore, a booster pump is installed at the connection point between the hydraulic shear and the hydraulic valve in the hydraulic shear mechanism.

[0014] Furthermore, the front operating console is a front-mounted type.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model utilizes an explosion-proof hydraulic excavation and repair integrated mechanism to mill and repair roadways. It can not only crush, excavate, and load, but also quickly switch between five functions: breaking, shoveling, loading, transporting, and anchor bolt cutting. This greatly reduces manual labor and truly realizes the mechanization of roadway maintenance.

[0017] The system achieves accurate positioning of the working position through a rotary reducer and boom cylinder, and enables continuous tunnel repair operations through a crawler walking mechanism. It can form a tunnel in one go, with good construction efficiency and economy, reducing the labor intensity of workers, improving mining safety, effectively improving the tunnel working environment, and accelerating the speed of tunnel excavation and repair operations.
