Problems solved by technology

[0003] 1. In the process of using the existing loader to excavate the coal mine underground, due to the limitation of the working space and the function of the loader, when the loader encounters a high-hardness rock layer or a large broken rock block on the excavation face, the existing technology must first After the loader exits the working face and the rock drill completes the rock-breaking drilling process, the excavation and loading work can be continued
The above-mentioned existing technical scheme increases the construction process, and cannot achieve effective tunneling and loading effects
Even though some backhoe loaders are equipped with rock drilling function, due to the irrationality of their design structure, the operation efficiency of the equipment is low, which seriously affects the driving speed of the roadway
[0004] 2. During the excavation process of the roadway, due to the influence of the movement of the overlying rock layer and the effect of the support, the surrounding rock of the roadway may be unstable, and it is also limited by the working space and the function of the loader. At this time, the loader needs to be withdrawn from the working face first. The drilling process is completed by the bolt drilling rig, and the tunneling and loading work can only be continued after the bolt and the surrounding rock form a common bearing body, which seriously affects the operation of the working face
[0005] 3. The existing backhoe loaders (especially in underground projects such as coal mines or tunnels) can only perform a single function of slag removal and transportation, which has a relatively single function and low operating efficiency

Embodiment Construction

[0029] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, the advantages of the present invention are clearer and easier to understand through the description.

[0030] Referring to the accompanying drawings, it can be seen that the excavator loader integrated with drilling, bolting and rock breaking for underground mines is characterized in that it includes a walking part 2 that can walk underground, and is installed on the upper part of the rear end of the walking part 2 and can move together with the walking part 2. Body 1, a frame 3 that is installed on the upper part of the front end of the running part 2 and can move together with the running part 2, the rear end of the frame 3 is connected with the front end of the body 1, and the middle part of the body 1 and the middle part of the frame 3 ar...

Abstract

The invention discloses a mining underground drilling, anchoring and rock breaking integrated excavation type loader, and relates to an excavation type loader used underground. The loader comprises a walking portion, a machine body and a machine frame. The rear end of the machine frame is connected with the front end of the machine body. The middle of the machine body and the middle of the machine frame are provided with lifting mechanisms correspondingly. The upper portions of the lifting mechanism are provided with a connection frame fixed between the machine body and the machine frame. The connection frame is provided with a slagging-off mechanism. The front end of the slagging-off mechanism is provided with a rock braking mechanism. The lower portion of the front end of the machine frame is connected with a front shovel portion. The rear end of the machine body is connected with a rear support. The left side and the right side of the slagging-off mechanism are each provided with a sliding rail installed on the machine frame. Anchoring rod mechanisms are installed on the sliding rails and can slide on the sliding rails. Excavation and anchoring integrated operation can be achieved in a narrow roadway, working time is greatly shortened, and safety of underground work is improved.

Description

technical field [0001] The invention relates to an excavating loader used underground, in particular to an integrated excavating loader for mining, drilling, anchoring and rock breaking. Background technique [0002] The backhoe loader is a comprehensive excavation equipment integrating excavation, loading, and walking. It is mainly used for the collection, transportation and loading of gravel and soil materials in tunnel excavation, mining engineering, water conservancy engineering and other projects. The current backhoe loaders mainly have the following deficiencies: [0003] 1. In the process of using the existing loader to excavate the coal mine underground, due to the limitation of the working space and the function of the loader, when the loader encounters a high-hardness rock layer or a large broken rock block on the excavation face, the existing technology must first After the loader is withdrawn from the working face, and the rock drilling machine completes the roc...
