Dry wet-type drill box of anchor rod drill carriage

Abstract

The invention relates to a dry wet-type drill box of an anchor rod drill carriage, which mainly consists of an upper box body, a lower box body, a transmission shaft, a drill bushing, a drill rod, a water seal, a locking disc, a lower end cover, a framework sealing seat, a floating seal, a hydraulic motor, a hydraulic motor connecting block, a liquid preparing plate, a hydraulic motor shaft gear, a transmission shaft gear and a bearing; wherein the drill box can be used in both a dry dedusting state and a wet dedusting state of the anchor rod drill carriage, and takes the cycloid hydraulic motor as power to drive the hydraulic motor shaft gear and the transmission shaft gear to rotate, thus driving the drill bushing and the drill rod to drill holes. By adopting full-sealing structure and combining framework seal, the floating seal, a sealing ring and the water seal, the drill box prevents dry-type boring dust from entering and prevents dust-containing water of wet-type atomizing boring dust removal from entering, thus leading the drill box to have drilling operation in a full-closed state. The drill box is advanced and reasonable in design, compact in structure, convenient in use and installation, safe, stable and reliable, and has dual purposes of dry and wet dust removal and good universality, thus being an ideal drill box of the anchor rod drill carriage and used on similar equipment.

Description

technical field [0001] The invention relates to a wet and dry drilling box of a rock bolter, belonging to the technical field of design and manufacture of components of a rock bolter in a coal mine. Background technique [0002] In the roadway excavation under the coal mine, in order to prevent the roadway from collapsing, it is necessary to support the roof and both sides of the roadway. There are many types of support, but the bolt support is the most used. In order to install the bolt, it must be installed in the roadway. Drilling is carried out on the wall, and some use artificial drilling rigs for drilling. However, due to the large vibration of the drilling rig and the large swing of the drill pipe, the drilling position is difficult to grasp, and it is easy to deviate. The drilling quality is not high, the efficiency is low, and there are safety hazards .

[0002] In the roadway excavation under the coal mine, in order to prevent the roadway from collapsing, it is necessary to support the roof and both sides of the roadway. There are many types of support, but the most used is the bolt support. In order to install the bolt, it must be installed in the roadway. Drilling is carried out on the wall, and some use artificial drilling rigs for drilling. However, due to the large vibration of the drilling rig and the large swing of the drill pipe, the drilling position is difficult to grasp, and it is easy to deviate. The drilling quality is not high, the efficiency is low, and there are safety hazards

[0003] In large and medium-sized coal mines, bolters are often used for mechanized drilling, but some drilling rigs equipped with bolters have insufficient performance, low power, many mechanical failures, and cannot drill under dry and wet dust removal conditions at the same time. hole, this technology still needs further improvement
