Abstract
The utility model provides a horizontal side support stabilizing device of a heading machine, which is technically characterized in that a hydraulic system is connected with a side support oil cylinder, one section of the side support oil cylinder is linked with a rear support and the other end of the side support oil cylinder is connected with a connecting seat acted on the side wall of a laneway. One end of the side support oil cylinder is linked with the rear support through a joint bearing. The other end of the side support oil cylinder is movably hinged with the connecting seat through a ball head mounted on the side support oil cylinder. The side support oil cylinder is arranged in a guide sleeve which can slide back and forth in the rear support in a penetrating manner, an end cover is arranged on the outer side of the connecting end of the ball head and the side support oil cylinder, the end cover is mounted at one end of the guide sleeve and the side support oil cylinder is connected with the guide sleeve through the end cover. The horizontal side support stabilizing device of the heading machine has the advantages that the overall machine of the hard rock heading machine is good in stability, the structure is simple, the range of application is wide and the effects are significant.
Description
Technical field
The utility model relates to a kind of horizontal side supporting fixing device of coal mine roadway development machine, particularly a kind of hard rock mole.
Background technology
Domestic development machine mainly is to be used for coal petrography and half coal petrography, and the development machine of big section, high rigidity (more than the 80Mpa) also is in development at home.At present, during the tunneling machine cutting hard rock of China at the big section (20M of cut
2More than), the driving in half rock gangway road and high rigidity total rock tunnel, machine vibration is big during the cut hard rock, the machine lateral sliding, complete machine stability is bad.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and a kind of development machine horizontal side supporting fixing device is provided.Can solve existing development machine (especially hard rock mole) at the big section (20M of cut
2More than), the driving in half rock gangway road and high rigidity total rock tunnel, machine vibration is big during the cut hard rock, machine lateral sliding, the problem that complete machine stability is bad.
The purpose of this utility model is achieved in that and comprises side support cylinder, back support, fairlead, bulb, Connection Block, end cap.It is characterized in that be provided with hydraulic system and the back is supported, the back is provided with the side support cylinder in supporting, hydraulic system links to each other with the side support cylinder, one section of the side support cylinder with after support connect, the other end links to each other with the Connection Block that acts on the tunnel sidewall.One end of side support cylinder supports with the back by oscillating bearing and connects.The side support cylinder other end is movably hinged by bulb and the Connection Block that is installed on the side support cylinder.The side support cylinder is set in the fairlead that can reciprocatingly slide in the back is supported, and the bulb and the side support cylinder link outside are provided with end cap, and end cap is installed the end with fairlead, and the side support cylinder links to each other with fairlead by end cap.The matching used side support cylinder of horizontal side supporting fixing device, bulb, Connection Block, fairlead are three covers: the left side that the back is supported is provided with two covers, and the right side is provided with a cover.
Adopt stretching of hydraulic control side support to adapt to the tunnel of different in width, and then increase the transverse horizontal arm of force, the sidewall of power taking in the tunnel reduces the vibration of development machine.When an end of side support arrives the sidewall in tunnel, because the effect of tunnel sidewall load, the side support cylinder of this end stops elongation, and the side support cylinder of the other end works on up to the sidewall that arrives other end tunnel, and this horizontal side bracing or strutting arrangement has been carried out previous preparation for driving.
The beneficial effects of the utility model are:
1, is mainly used in the big section (20M of solution cut
2More than), when high rigidity (more than the 80Mpa), half rock gangway road and high rigidity total rock tunnel, development machine causes vibration violent owing to transverse horizontal power is excessive, even unbalance problem.Provide good technical support for further developing hard rock mole.
2, solved the problem of hard rock mole complete machine stability difference, the anti-tilting moment that improves development machine by the transverse horizontal arm of force that increases complete machine improves the stability of complete machine.
3, give side support cylinder fuel feeding by hydraulic system, it is flexible in the side of back support that the side support cylinder drives fairlead.It is flexible that the side support cylinder drives fairlead, one end of side support cylinder adopts oscillating bearing to connect with the back support, the other end of another distolateral support of side support cylinder adopts fairlead and bulb to connect with Connection Block, bulb is with after Connection Block is connected, Connection Block acts on the sidewall in tunnel, and power taking and sidewall reach the effect of stablizing development machine.
4, during the development machine operation, the Oil pump electrical machinery of hydraulic system drives hydraulic pump works and gives side support cylinder fuel feeding, controls the stroke that side supports by the side support cylinder, can satisfy the use in the wide tunnel of 3.6～6m.This apparatus structure is simple, and usage range is wide, and effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model development machine horizontal side supporting fixing device.
Fig. 2 is an A place enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing present embodiment is described further
By Fig. 1-2 as can be known, the back is supported in 2 side support cylinder 1 is set, and (hydraulic system is meant the device that power is provided to oil cylinder to hydraulic system.) link to each other with side support cylinder 1, an end of side support cylinder 1 supports 2 by oscillating bearing and back and connects, and the side support cylinder other end is movably hinged with Connection Block 5 by the bulb 4 that is installed on the side support cylinder.Side support cylinder 1 is set in and can supports fairlead 3 one ends that reciprocatingly slide in 2 in the back, and side support cylinder 1 links to each other with fairlead 3 by end cap 6.The matching used side support cylinder of horizontal side supporting fixing device, bulb, Connection Block, fairlead are three covers: the left side that the back is supported is provided with two covers, and the right side is provided with a cover.
The utility model provides power to hydraulic pump by the hydraulic electric motor of hydraulic system, hydraulic pump arrives side support cylinder 1 to hydraulic oil pressure, three side support cylinders 1 are positioned at the back and support 2, the back is supported in 2 three fairleads 3, side support cylinder 1 drives fairlead 3 work, the working end of side support cylinder 1 links to each other with Connection Block 5 by bulb 4, and Connection Block 5 acts on the sidewall in tunnel.
