Abstract
The utility model relates to a drilling equipment for a coal mine anchor supporting, in particular to a multifunctional hydraulic jumbolter whose top hole and side hole can be drilled and rotate bidirectionally. The machine head part of the multifunctional hydraulic jumbolter is connected with a hydraulic supporting leg through a pin shaft and a dog bolt; an operating mechanism is connected with the hydraulic supporting leg through an oil distributing shaft; the reversal valve of the multifunctional hydraulic jumbolter is connected with a hydraulic motor in the machine head part; the switch valve of the multifunctional hydraulic jumbolter is connected with water jacket pipe in the machine head section. Compared with prior art, the utility model has the advantages of compact and reasonable structure, strong adaptability, and simplifying the device configuration of drivage working surface, which is helpful to on-site management and improve the speed drivage construction; the rotary direction of the jumbolter can be changed optionally; the utility model satisfies the requirement of using full-thread equal strength anchor rod, and has an important meaning of improving the installation quality and anchoring strength of the full-thread equal strength anchor rod and giving full play to the superiority.
Description
Technical field
The utility model relates to a kind of rig of mine bolt supporting, and definite says, is a kind of top eye, and branch hole can both bore, and multifunction hydraulic jumbolter that can two-way rotation.
Background technology
At present, domestic mine bolt supporting extensive use the overhead type jumbolter, the shortcoming of this rig is: can only bore top eye, can not bore branch hole, therefore, driving face no longer coal blending electric drill or electric rock drill bores branch hole, causes the equipment configuration complicated; Can only turn right, can not turn left, incompatibility is applied the needs of most advanced, the most rational full thread equal strength anchor pole, influences and has restricted China's coal-mine Application of Bolting Support and development.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of top eye of can boring is provided, and can bore branch hole again, and multifunction hydraulic jumbolter that can the two-way rotation in the left and right sides.
The technical solution of the utility model is: chain-drive section is connected with hydraulic leg with eyelet bolt by bearing pin, operating mechanism is connected with hydraulic leg by oil distribution shaft, the reversal valve of operating mechanism is connected by high-pressure oil pipe with hydraulic motor in the chain-drive section, and its switch valve is connected with water jacket water pipe in the chain-drive section.
Compared with prior art, the utility model has the advantages that: compact integral structure is reasonable, compliance is strong, the top eye, branch hole, bolthole, the anchor cable hole, different azimuth such as roasting and boiling as two means of processing crude drugs hole, the hole of different-diameter and different purposes can both be bored, need not dispose other drilling machines such as electric coal drill or electric rock drill again, simplified the configuration of driving face equipment, help field control, improve tunneling construction speed, the needs that use full thread equal strength anchor pole have been satisfied in the arbitrarily conversion of the direction of rotation of rig, to improving full thread equal strength anchor pole installation quality and anchoring strength, it is significant to give full play to its superiority
Description of drawings
Description of drawings of the present utility model is as follows;
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the sectional drawing of the utility model output shaft
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.As shown in Figure 1, chain-drive section 1 of the present utility model, be connected with hydraulic leg 4 with eyelet bolt 8 with bearing pin 2, bearing pin 2 is on axillare 3, operating mechanism 11 is connected with hydraulic leg 4 by oil distribution shaft 9, and the reversal valve in the operating mechanism 11 is connected with high-pressure oil pipe (flexible pipe) 10 with hydraulic motor in the chain-drive section 1.Reversal valve in the operating mechanism has three positions, left, center, right, the left-handed rotation of the hydraulic motor of corresponding chain-drive section, stops or dextrad rotation.Switch valve in the operating mechanism 11 is connected with water jacket 6 water pipes 7 (flexible pipe) in the chain-drive section 1.As shown in Figure 2, cylindrical hole 12, hexagonal hole 13 and two breach 14 are arranged in the output shaft 5 of chain-drive section 1.
The course of work of the present utility model: as shown in Figure 1, bearing pin 2 and eyelet bolt 8 are chain-drive section 1 and hydraulic leg 4 firm linking together.High-pressure oil pipe, water pipe 7 are flexible pipe, just can handle hydraulic motor forward or reverse in the chain-drive section 1 flexibly by operating mechanism 11, and operating hydraulically operated supporting leg 4 elongates or shortens, and bore the top eye.If eyelet bolt 8 is unclamped, make chain-drive section 1 change an angle around bearing pin 2, can bore branch hole, this angle is 0 °-90 °, practical application is generally in 0 ° of-50 ° of scope.As shown in Figure 2, cylindrical hole 14 and hexagonal hole 13 in the output shaft 5 can be installed hexagonal kelly, cylindrical hole 14 and breach 12 can be installed twist drill rods, therefore, just can be according to the hard degree of tunnel rock or coal, six sides or twist drill rods are changed in the different requirements of skyhook, anchor cable or roasting and boiling as two means of processing crude drugs very easily, bore different-diameter, the bolthole of different purposes, anchor cable hole or roasting and boiling as two means of processing crude drugs hole.
Claims (2)
1, a kind of multifunction hydraulic jumbolter, comprise chain-drive section, hydraulic leg and operating mechanism, it is characterized in that: chain-drive section is connected with eyelet bolt by bearing pin with hydraulic leg, operating mechanism is connected with hydraulic leg by oil distribution shaft, its reversal valve is connected by high-pressure oil pipe with hydraulic motor in the chain-drive section, and its switch valve is connected with water jacket water pipe in the chain-drive section.
2, multifunction hydraulic jumbolter according to claim 1 is characterized in that, is provided with in the output shaft of chain-drive section cylindrical hole, hexagonal hole and two breach that drilling rod is used are installed.
