Description
Technical field
The utility model relates to coal-mine integrated-mining equipment field, more specifically, relates to a kind of lateral thruster, hydraulic support and fully-mechanized mining equipment of hydraulic support.
Background technology
Hydraulic support is the important component part of fully-mechanized mining equipment, is that hydraulic support can support and control the top board of work plane effectively for controlling the works of coal-face mine pressure, and isolation goaf prevents that spoil from entering stope and advancing conveyer.The box-structure that the beam body of the back timber of hydraulic support, caving shield is normally comprised of parts such as top board, cover plate, outer main muscle and interior main muscle.At Liang Tishang, lateral thruster is installed, lateral thruster major function be: keep the sealing between adjacent hydraulic support, anti-leak-stopping cash; Adjust the attitude of hydraulic support, and, the guiding of frame process moved.
Fig. 1 and Fig. 2 show in correlation technique and are stored in the set a roof beam in place sectional view of two kinds of typical lateral thrusters on body of same hydraulic supporting, and wherein the lateral thruster shown in Fig. 2 also can be described as spring supporting device.As shown in the figure, lateral thruster mainly comprises: the first side guard board 21 ' and the second side guard board 22 ' that are installed on beam body 1 ' both sides; Be arranged on the thruster actuator 3 ' of beam body 1 ' box-structure inside; Be positioned between first thruster guide rod the 41 ', the first thruster guide rod 41 ' between thruster actuator 3 ' and the first side guard board 21 ' and the first side guard board 21 ' for removably connecting; Be positioned between second thruster guide rod the 42 ', the second thruster guide rod 42 ' between thruster actuator 3 ' and the second side guard board 22 ' and the second side guard board 22 ' for removably connecting; Pilot sleeve the 6 ', the first thruster guide rod 41 ' and the second thruster guide rod 42 ' that are arranged in beam body 1 ' are set in pilot sleeve 6 '.
Thruster actuator 3 ' in Fig. 1 is hydraulic cylinder, the two ends of hydraulic cylinder removably connect by bearing pin 51 ' and the first thruster guide rod 41 ', the second thruster guide rod 42 ' respectively, in addition, on the first thruster guide rod 41 ' and pilot sleeve 6 ', be coaxially arranged with the first hole, in the first hole, be equipped with bearing pin 52 '; On the second thruster guide rod 42 ' and pilot sleeve 6 ', be coaxially arranged with the second hole, in the second hole, be equipped with bearing pin 53 ', and the axis of bearing pin 52 ' and bearing pin 53 ' is all perpendicular with the axis of pilot sleeve 6 '.Thruster actuator 3 ' in Fig. 2 is spring, and spring housing is located in pilot sleeve 6 ' and is clamped between the first thruster guide rod 41 ' and the second thruster guide rod 42 ', makes spring and the first thruster guide rod 41 ', the second thruster guide rod 42 ' Elastic Contact.
When hydraulic support is during in travel position, bearing pin 52 ' is positioned at the first hole, and bearing pin 53 ' is positioned at the second hole, and hydraulic cylinder shrinks, and spring is compressed, and the first side guard board 21 ' and the second side guard board 22 ' are all lockable, and can not stretch out.When hydraulic support carries out supporting operation, by removing in bearing pin 52 ' and bearing pin 53 ', make one in the first side guard board 21 ' or the second side guard board 22 ' can be under the effect of thruster actuator 3 ' the protruding or retraction of relative beam body 1 ', another one is in locking-in state, the side guard board that can do expanding-contracting action under supporting job state is also referred to as movable side protection plate, and the side guard board being lockable under supporting operation is also referred to as fixation side backplate.Movable side protection plate after opening and adjacent hydraulic support keep in touch realizes sealing, can prevent that between support, leaking cash brings harm to support component and operator, also plays the effect of roof supporting simultaneously.And when coal-face variation needs the position of translation activity side guard board and fixation side backplate, can realize by changing the lockup state of installation direction, transposing bearing pin 52 and the bearing pin 53 of thruster jack.
Hydraulic support is when supporting job state, the movable side protection plate of opening can bear larger roof pressure, and transfer the pressure on the thruster guide rod being connected with movable side protection plate, for guaranteeing that the thruster guide rod being connected with movable side protection plate has enough support strengths, in prior art, the first thruster guide rod 41 ' and the second thruster guide rod 42 ' all adopt solid construction, and the thruster guide rod of solid construction is generally processed into by metal bar.Because of every hydraulic support, can use many cover lateral thrusters, the first thruster guide rod 41 ' and the usage quantity of the second thruster guide rod 42 ' on every hydraulic support are more, and weight is also larger, is unfavorable for reducing weight and the cost of hydraulic support.
