Specific embodiment
1-4, is described in detail below with temporary support device to development machine of the present utility model below in conjunction with the accompanying drawings.
As shown in accompanying drawing 1,2,3, development machine temporary support device of the present utility model, the temporary support device include bottom
Plate 1, and the first column 2, the second column 3, folding ram 4 and the upper frame 5 being arranged above base plate 1.
1 horizontal positioned of base plate, base plate 1 are fixedly connected on downwards the cover plate upper surface of development machine cantilever part.
First column 2 and 3 Parallel Symmetric of the second column are arranged, and the bottom of the first column 2 and the second column 3 is cut with scissors separately down
It is connected on front side of the upper surface of base plate 1, the top of the first column 2 and the second column 3 is hingedly connected in the middle part of the lower surface of upper frame 5.
Folding ram 4 is arranged between the first column 2 and the second column 3, and the perpendicular that folding ram 4 is located is parallel
In the first column 2 be located perpendicular, folding ram 4 be located perpendicular also parallel with the second column 3 be located vertical
Plane, the bottom of folding ram 4 are articulated with rear side of the upper surface of base plate 1, and the expansion link top of folding ram 4 is cut with scissors by bearing pin 9
Connect the first column 2 and the second column 3 in succession, and bearing pin 9 and the first column 2, the pin joint of the second column 3 are misaligned vertical in first
Post 2, the end of the second column 3.
During use, the first column 2 and the second column 3 are driven around its own by the length of telescopic bar for adjusting folding ram 4
Bottom is rotated with the pin joint of base plate 1, and then changes the height of upper frame 5, reaches the top for withstanding development machine cantilever part upwards
The purpose in tunnel.
The bearing pin 9 on 4 expansion link top of folding ram is articulated and connected in the first column 2 and the second column 3 near the end of base plate 1
Portion.When the expansion link of folding ram 4 protrudes outwardly to most long, the angle of the first column 2 and the second column 3 with 1 upper surface of base plate
Obtuse angle is gradually increased to, to ensure the stability of supporting.
As this utility model is installed in the cantilever part of development machine, therefore, the area of upper frame 5 should reduce as far as possible,
But, need the area of supporting very big at the top of tunnel, for this purpose, combining accompanying drawing 4, be cuboid framework structure based on existing upper frame 5,
Rollover stand 7 is connected with by linkwork 6 respectively in the left and right sides of 5 lower surface of upper frame, linkwork 6 has restriction rollover stand
The locating part of 7 positions, locating part can select handss to twist bolt 8.In Bracing Process, by linkwork 6, rollover stand 7 is entered
Pedestrian's work auxiliary operation, and 7 position of the fixation rollover stand of bolt 8 is twisted by manipulator, rollover stand 7 and 5 keeping parallelism of upper frame is made, with
Expand the supporting scope of upper frame 5.
As the position of upper frame 5 is changed by the rotation of the first column 2 and the second column 3, so, do not make
When with this utility model or using this utility model is finished, manual operation rollover stand 7 makes rollover stand 7 in linkwork 6
In the presence of overlap to upper frame 5, with not additionally take tunnel inner space, then adjust folding ram 4 expansion link long
Degree, realizes the purpose for reducing upper frame 5.
It should be noted that combining accompanying drawing 1,2, when not using this utility model, the expansion link of folding ram 4 is generally in
Retracted mode, the first column 2 and the second column 3 are minimum with the angle of 1 upper surface of base plate, and upper frame 5 also follows the first column 2 and the
Two columns 3 fall above base plate 1, the space of the occupancy coal mine roadway for making temporary support device as little as possible.
Also, it should be noted combining accompanying drawing 3,4, when beginning to use this utility model, the expansion link of folding ram 4 starts
Protruding, i.e. the first column 2 and the second column 3 are hinged the pin joint of the end of upper frame 5 rotating around its own with base plate 1 upwards
Rotation, until upper frame 5 withstands the top tunnel of development machine cantilever part upwards, meanwhile, manual operation rollover stand 7 make its to top
Frame 5 is parallel, and is fixed with the stubborn bolt 8 of handss, to increase the supporting area of upper frame 5；Withstood in 5 position change of upper frame upwards
During the top tunnel of development machine cantilever part, realize that the self adaptation of upper frame 5 is levelling, whole process achieves gib
Do mechanization operation, reduce the operation intensity of Anchor Care workman, improve the drivage efficiency of development machine.
In structure of the present utility model description, it should be noted is that, the expression side such as "front", "rear", "left", "right"
Position word be all based on accompanying drawing to describe, actually used during, be not limited in above-mentioned position.
In sum, above content is only in order to illustrating the technical solution of the utility model, rather than this utility model is protected
The restriction of scope, although the specific embodiment part has been made to explain to this utility model, the ordinary skill of this area
Personnel should be appreciated that and the technical solution of the utility model can be modified or equivalent, new without deviating from this practicality
The spirit and scope of type technical scheme.
