Crawler Chassis Module and Bolting Rig

Abstract

The invention provides a crawler-type chassis module and an anchor drill truck, comprising a vehicle frame, a dozer mechanism arranged at the front of the vehicle frame, and a walking mechanism arranged at the bottom of the vehicle frame; the walking mechanism includes a walking bracket, a crawler track assembly, Tensioning device and buffering device; the tensioning device is arranged on the walking bracket and has a telescopic end that can be extended and retracted along the front and rear directions; the buffering device has a guide part, an elastic part and a positioning part; when the positioning part is installed on the guide part, the positioning part is sandwiched Between the rear end of the elastic part and the part where the traveling bracket is in sliding contact with the guide part, after the pushing force of the tensioning device is canceled, the guide part can also keep the elastic tension state under the action of the elastic force. In the tracked chassis module and the rock bolt provided by the present invention, even after the pushing force of the tensioning device is cancelled, the guide portion can keep in contact with the guide wheel and provide effective tensioning, so that the tensioning device can be effectively tensioned. It is separated from the guide part to avoid damage to the tensioning device and prolong its service life.

Description

technical field [0001] The invention belongs to the technical field of mine drilling rigs, and in particular relates to a crawler-type chassis module and a rock bolt drilling rig. Background technique [0002] The status and role of coal as the main energy source in my country is difficult to change in the short term. With the urgent requirement of intelligent, efficient and unmanned coal mining in my country, safe and efficient production has become one of the main indicators of coal mining. . At the same time, the vast majority of coal mining in my country is underground mining. In the face of complex geomorphological and geological conditions, the form of roadway anchoring is still severe. The traditional artificial anchoring is not only inefficient, but also has a large number of potential safety hazards. Although there are already some bolts in the market Drill rigs to replace manual anchoring operations. Existing rock bolters mostly use crawler-type chassis modules. Ho...

At the same time, the vast majority of coal mines in my country are underground mining. Faced with complex geomorphic and geological conditions, the roadway anchoring form is still severe. The traditional artificial anchoring is not only inefficient, but also has a large number of potential safety hazards. Although there are already some anchors in the market Drilling car to replace manual anchoring work

Most existing rock bolters use crawler-type chassis modules. However, the tensioning device of the existing crawler-type chassis modules uses hydraulic cylinders to directly contact the guide wheels. The force will still directly act on the hydraulic cylinder, resulting in easy damage to the hydraulic cylinder, short service life and high cost of use
