The specific embodiment
The structural representation of the blocking device of the hydraulic chock running valve group that Fig. 1 provides for the embodiment of the present invention, as shown in Figure 1, this device specifically comprises: a train wheel bridge 1 is arranged at the top of operating valve set 2, one lower plate 3 is arranged at the bottom of operating valve set 2, the first extension 4 that train wheel bridge 1 deviates from operating valve set 2 directions is provided with two holes 5, the second extension 6 that lower plate 3 deviates from operating valve set 2 directions is provided with two holes 7, when hydraulic support remains static, for the control crank 9 of guaranteeing to be connected with operating valve set 2 is not arbitrarily pulled, the first extension 4 that two bars 8 are deviated to operating valve set 2 directions from train wheel bridge 1 is provided with two holes 5 and passes, and from the second extension 6 that lower plate 3 deviates from operating valve set 2 directions, be provided with two holes 7 and pass, due to the gap that is formed for the control crank 9 that is connected with operating valve set 2 of restriction between two bars 8 and pulls, thereby having limited control crank 9 can not swing, avoided the potential safety hazard that collision brings unintentionally.
The blocking device of the hydraulic chock running valve group that the embodiment of the present invention provides, specifically comprise: a train wheel bridge is arranged at the top of operating valve set, one lower plate is arranged at the bottom of described operating valve set, the first extension that described train wheel bridge deviates from described operating valve set direction is provided with two holes, the second extension that described lower plate deviates from described operating valve set direction is provided with two holes, two bars are arranged in two holes on described the first extension and two holes on described the second extension, between described two bars, be formed for the gap that the control crank that is connected with described operating valve set of restriction is pulled, thereby clash into when there is mistake, during the influence factors such as maloperation, operating grip maloperation has obtained effective control, the potential safety hazard of effectively avoiding the maloperation of operating grip to bring, improved safety factor.
The structural representation of the blocking device of another hydraulic chock running valve group that Fig. 2 provides for the embodiment of the present invention, as shown in Figure 2, based on embodiment illustrated in fig. 1, the top that two bars 8 hole 5 from the first extension 4 extends out is provided with the positioning head 10 for axial location bar.Be understandable that, positioning head 10 is specifically as follows nut, catch, its shape specifically can comprise: square, circular etc., the size of positioning head 10 can be determined according to the size in hole 5, as long as meet two bars 8, because Action of Gravity Field makes positioning head 10, from hole, 5 does not pass through, and can make bar 8 be fixedly arranged between lower plate, be formed under hydraulic support inactive state, for limiting the positioning head in the gap that control crank 9 pulls, can adopt.Optimally, positioning head 10 is an annulus (as shown in Figure 2), and such as nut, the diameter of annulus is greater than the diameter in the hole 5 on the first extension 4, thereby two bars 85 are not passed through from hole because Action of Gravity Field makes positioning head 10, can make bar 8 be fixedly arranged between train wheel bridge 1 and lower plate 3.
The structural representation of the blocking device of another hydraulic chock running valve group that Fig. 3 provides for the embodiment of the present invention, as shown in Figure 3, based on embodiment illustrated in fig. 2, when hydraulic support in handling process owing to rocking or other maloperations easily make two bars 8 skid off from hole, the bottom that in the present embodiment, two bars 8 hole 7 from the second extension 6 extends out is provided with pin 11, prevented that two bars 8 from skidding off from hole 7, guaranteed that hydraulic support still can limit the activity of control crank 9 in handling process.
The structural representation of the blocking device of another the hydraulic chock running valve group that Fig. 4 provides for the embodiment of the present invention, as shown in Figure 4, based on embodiment illustrated in fig. 3,
Train wheel bridge 1 is provided with two holes 13 along the 3rd extension 12 of operating valve set 2 sides, when operation hydraulic support, two holes 13 by two bars 8 from the 3rd extension 12 are passed, thereby no longer the activity of control crank 9 are limited, and can make control crank 9 swing back and forth.
For above-described embodiment, specifically describe for example below by sewing up screw rod train wheel bridge and lower plate are arranged in operating valve set, and the concrete bar size arranging and wear circular hole on clamping plate, with under hydraulic support static state, by the activity of two bars restriction control cranks.Be specially:
Train wheel bridge is arranged on the upper end of hydraulic chock running valve group, and anterior 2 of the screw rod upper ends bolt of sewing up of operating valve set is turned on, and train wheel bridge is penetrated to the upper end of stitching screw rod by the hole of spacing 104mm, by bolt tightening.Lower plate is arranged on the lower end of hydraulic chock running valve group, and anterior 2 bolts sewing up screw rod lower end of operating valve set are turned on, and lower plate is penetrated to the lower end of stitching screw rod by the hole of spacing 104mm, by bolt tightening.When hydraulic support remains static, for guaranteeing that hydraulic support is failure to actuate, the bar that is 500mm by length, two holes that are 60mm from train wheel bridge spacing with nut end are passed, and through lower plate, guaranteed that hydraulic chock running valve handle can not swing, avoided the potential safety hazard that collision brings unintentionally.When operation hydraulic support, two holes that the bar that is 500mm by length is 150mm with nut end from train wheel bridge spacing are passed, and can make like this operating valve set handle swing back and forth.Wherein, train wheel bridge is made of 3mm steel plate, and lower plate is made of 3mm steel plate, and bar is that ￠ 10mm round steel is made, and one end is welded with nut, and length is 500mm.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
