Abstract

The invention discloses a rapid clamping metamorphic mechanism of a borer blocking platform of a hydraulic drill rig. An auxiliary arm and a sliding arm are hinged onto a machine body; two clamping blocks are respectively hinged to the auxiliary arm and the sliding arm; the clamping blocks are used for clamping a borer rod; the tail end of the auxiliary arm is hinged to one end of a hydraulic cylinder; a cylinder sliding block is hinged to the other end of the hydraulic cylinder; a sliding track is mounted on a sliding arm; the cylinder sliding block is connected with the sliding track; sliding track limiting blocks are mounted at two ends of the sliding track; springs are mounted between the cylinder sliding block and the sliding track limiting blocks. The rapid clamping metamorphic mechanism has the benefits that the borer blocking platform of the hydraulic drill rig is enabled to rapidly clamp the bore rod and keep certain clamping force. In addition, the rapid clamping metamorphic mechanism is simple in structure and has a function of automatically switching the working states.

Description

Rapid clamping mechanism of hydraulic drilling truck clamping platform

technical field

The invention relates to the field of construction machinery mechanisms, in particular to a quick-clamping cell-changing mechanism for a hydraulic drilling truck clamping platform.

Background technique

During the working process of rock drilling machinery, due to the work of connecting rods and changing rods, it is necessary to quickly clamp the drill rod, and at the same time ensure the clamping force after the rapid clamping. In order to ensure the clamping force, the traditional clamping mechanism makes the clamping force The clamping speed is very slow, and increasing the clamping speed cannot guarantee the clamping force.

Contents of the invention

In view of the above-mentioned problems, the object of the present invention is to provide a quick-clamping cell-changing mechanism for a hydraulic drilling truck clamping table.

The technical solution of the present invention is: the quick-clamping cell-changing mechanism of the drilling platform of the hydraulic drilling truck, including the body, the clamping block, the drill rod, the auxiliary arm, the sliding arm, the hydraulic cylinder, the spring, the slide rail, the oil cylinder slide block, and the slide rail The limit block, the auxiliary arm and the sliding arm are hinged on the body, the two clamping blocks are respectively hinged with the auxiliary arm and the sliding arm, the clamping block clamps the drill rod, the end of the auxiliary arm is hinged with one end of the hydraulic cylinder, and the other end of the hydraulic cylinder One end is hinged with an oil cylinder slide block, the slide rail is installed on the slide arm, the oil cylinder slide block is connected with the slide rail, slide rail limit blocks are installed at both ends of the slide rail, and a spring is installed between the oil cylinder slide block and the slide rail limit block.

Beneficial effects of the present invention: the present invention enables the clamping platform clamping mechanism of the hydraulic drilling rig to clamp quickly and at the same time ensure a certain clamping force after clamping. At the same time, the mechanism also has a simple structure and the function of automatically switching working states.

Fig. 1 is a structural schematic diagram of the present invention.

detailed description

Now in conjunction with accompanying drawing, the present invention is described in further detail.

As shown in Figure 1, the auxiliary arm 4 and the sliding arm 5 are hinged on the body 1, and the two clamping blocks 2 are respectively hinged with the auxiliary arm 4 and the sliding arm 5, the clamping block 2 clamps the drill rod 3, and the end of the auxiliary arm 4 One end of the hydraulic cylinder 6 is hinged, and the other end of the hydraulic cylinder 6 is hinged with a cylinder slider 9; The two ends of the slide rail 8 are provided with a slide rail limiting block 10, and a spring 7 is installed between the oil cylinder slider 9 and the slide rail limiting block 10.

When the fast clamping mechanism of the clamping table is tightened, due to the effect of the spring 7, the oil cylinder slider 9 is pressed against the end of the slide rail 8 closest to the clamping block 2. At this time, the hydraulic cylinder 6 can be extended to make the clamping The holding block 2 moves quickly to position the drill rod 3. When the drill rod 3 is positioned, the hydraulic cylinder 6 continues to extend, so that the cylinder slider 9 overcomes the spring force and slides to the other end of the slide rail 8, so that the lever arm of the slide arm 5 increases. The clamping force to the drill rod 3 is increased, and the clamping action is completed.
