Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
By Fig. 1 to Fig. 3 it is found that the utility model includes horizontal positioned and upper end opening a cabinet 1, the bottom of cabinet 1
Portion is equipped with the hydraulic cylinder 16 that cabinet 1 can be made to move up and down, and plate 2 horizontal and moving up and down is equipped in cabinet 1, plate 2
Upper surface is evenly equipped with multiple lower ending openings and box body moving up and down 3, is equipped with first that it can be made to reset upwards in box body 3
Pressure spring 4, the lower end of plate 2 are equipped with the bolt 5 vertically placed, and the lower section of bolt 5, which is equipped with, is rotatably connected on 1 bottom of cabinet and and spiral shell
The nut 6 that bolt 5 matches, the lead angle on bolt 5 is greater than bolt 5 and nut 6 is formed by the equivalent friction angle of screw pair,
The periphery of nut 6 is equipped with the second pressure spring 7 that it can be made to reset, rope 8 there are four circumference uniform distributions on the periphery of nut 6,
The outside of each side wall of cabinet 1 is hinged with an acclivitous inclined plate 9, and the other end of each rope 8 corresponds to case through it
The side wall of body 1 is simultaneously fixedly connected with inclined plate 9, is set with the third pressure spring 10 being placed between inclined plate 9 and side wall on rope 8, and second
The elastic strength of pressure spring 7 is greater than the elastic strength of third pressure spring 10.
In order to realize the better reset effect of the second pressure spring 7, the periphery of the nut 6 is equipped with annular groove 11, and second
Pressure spring 7 is placed in annular groove 11, and the notch of annular groove 11 is shrink mouth shape, and a fixed block 12, the second pressure are equipped in annular groove 11
One end of spring 7 is fixed on fixed block 12, and the other end is equipped with the compression bar 13 for being fixed on 1 bottom of cabinet, passes through annular groove 11
And the collective effect of fixed block 12 and compression bar 13 realizes and can be realized the promotion of fixed block 12 while rotating nut 6 and be placed in ring
The second pressure spring 7 in shape slot 11 squeezes compression bar 13 and realizes the compression of the second pressure spring 7.
It is more stable during plate 2 moves up and down in order to realize, there is a cunning on four lateral walls of the plate 2
Block 14, the side wall of cabinet 1 is equipped with the sliding slot 15 matched with sliding block 14, effective by the cooperation between sliding block 14 and sliding slot 15
To realize plate 2 more steady during level moves up and down.
The specific work process of the utility model is: the present apparatus is placed in the tunnel of mine by the present apparatus first when in use
It is interior, the hydraulic pump on hydraulic cylinder 16 is then opened, hydraulic pump is that hydraulic cylinder 16 provides power, pushes cabinet 1 by hydraulic cylinder 16
It moves upwards, in the process under the original state of the present apparatus, the first pressure spring 4 is in the box body 3 of relaxation state at this time and is in
Upward relaxation state, bolt 5 at this time do not contact nut 6 or contact but nut 6 cannot be driven to rotate, the initial shape of nut 6
State are as follows: nut 6 is in the second pressure spring 7 and the fixed block 12 being fixed in annular through groove 11 and the compression bar for being fixed on 1 bottom of cabinet
Realize that nut 6 tenses four uniformly distributed ropes 8 of its outside and makes this four ropes simultaneously in the outer of nut 6 under 13 collective effect
It is wound on disc and realizes the tightening to rope 8, pulling force suffered by rope 8 is from the second pressure spring 7 in the process
Provided elastic force, and be to be able to achieve this function to guarantee that the elastic force that can be provided of the second pressure spring 7 is greater than third pressure spring 10,
Therefore, it under original state, is drawn close around its articulated position to cabinet 1 under the pulling force of the tangible rope 8 of inclined plate 9, the during this
Three pressure springs 10 are squeezed power and realize the compression of its own.
With the elongation of hydraulic cylinder 16, the upward elongation of hydraulic cylinder 16 drives cabinet 1 to move upwards, the upward fortune of cabinet 1
Dynamic meeting is so that the upper surface of the box body 3 on plate 2 starts the top come into contact with to tunnel, at this time due to being mostly not at the top of tunnel
The state of rule, therefore when the upper surface of multiple box bodys 3 touches at the top of tunnel, being squeezed the box body 3 of power first can be to
To overcome extruding force, 4 stress of the first pressure spring that can realize that box body 1 squeezes below that moves down of box body 3 squeezes and makes it for lower movement
Trend and elastic potential energy with rebound continue to move up with cabinet 1, and pressure increases, and plate 2 starts to move downward, plate 2
The sliding block 14 that can be realized on plate 2 that moves down moved down in sliding slot 15, and bolt 5 is moved down and realizes its bolt
5 match with nut 6, since the lead angle on bolt 5 is greater than the equivalent friction that bolt 5 and nut 6 are formed by screw pair
Angle and drives spiral shell during bolt 5 moves downward so that will not generate self-locking during bolt 5 is meshed with nut 6
Mother 6 rotates, and the rotation of nut 6 can realize that the second pressure spring 7 exists in this rotation process so that the second pressure spring 7 follows nut 6 to rotate
Compression is realized under the action of fixed block 12 and compression bar 13, and realizes that the rope 8 being wrapped on 6 periphery of nut loosens, rope 8
Meeting is unclamped so that the power of compression third pressure spring 10 reduces, therefore realizes inclined plate 9 under the action of the bounce of third pressure spring 10
It struts, so that the upper end of inclined plate 9 is tilted to one end far from cabinet 1, in order to realize more convenient and fast collecting action, adjacent two
It can be connected through non-woven fabrics, grenadine etc. between inclined plate 9.
After the present apparatus is completed to support, control hydraulic cylinder 16 is moved down, and cabinet 1 is driven to move down, during this,
Plate 2 moves up, and realizes the disengaging that nut 6 and bolt 5 are realized under the requirement of the bounce of the second pressure spring 7, is being detached from
In the process, rope 8 is compacted herein and third pressure spring 10 is compressed again so that realize the upper end of inclined plate 9 close to cabinet 1, with
Cabinet 1 continue to move down, bounce provided by the first pressure spring 4 pushes box body 3 to reset, final to realize the present apparatus all components
Reset.
The present apparatus is laid on plate 2 by multiple box bodys 3, and realizes that the flexible of multiple box bodys 3 connects by the first pressure spring 4
It connects, during supporting at the top of tunnel, especially the is withstood by stone and soil property structure for such design method effective solution
At tunnel at the top of, can effectively increase the forced area of the present apparatus while also considerably increase the safety of the present apparatus.
The present apparatus realized to the tightening of rope 8 by the rotation of nut 6 and loosens process and complete folding and unfolding to inclined plate 9,
The setting of inclined plate 9 effectively solves during the present apparatus is withstood at the top of tunnel upwards, due to stress at the top of tunnel to
Under fall soil and fall rubble, destroy and damage present apparatus surrounding devices and the problem of staff.
The utility model is novel, clever structure, practical, by multiple box bodys that the supporting plane of the present apparatus is micro-
It is divided into multiple, and realizes that the present apparatus can be useful in more complex environment by way of flexible connection, while in support
Realize that inclined plate is opened and is collected to object is fallen in the process, so that the present apparatus is more safe and reliable.
