Putting 13 can stretch back and forth in the horizontal direction.
Specifically, lift bottom very heavy 12 is fixedly connected with pedestal 11, when hydraulic support does not move forward, lift bottom support device 13 is returned
In the first groove 111, lift bottom very heavy 12 is suspended vacantly on the pedestal 11 for contracting, when hydraulic support moves forward, lifts bottom support device
13 stretch out, and lift bottom very heavy 12 is supported when lift bottom very heavy 12 being made to work, so as to increase the contact area at lift bottom very heavy 12, makes lift bottom thousand
Jin 12 jacks up pedestal 11.
In one of the embodiments, as shown in figure 4, the lift bottom support device 13 includes babinet 131 and elapses very heavy
132, the passage very heavy 132 includes piston rod 1321 and oil cylinder body 1322, and the oil cylinder body 1322 is embedded in the case
In body 131, described 1321 one end of piston rod is embedded in the oil cylinder body 1322,1321 other end of piston rod with it is described
Pedestal 11 connects.By the way that oil cylinder body is embedded in babinet, piston rod one end is embedded in oil cylinder body, the other end and pedestal
Connection, makes lift bottom support device be fixedly connected with pedestal, so that lift bottom support device can support lift bottom very heavy.
In one of the embodiments, as shown in Figure 5 and Figure 6, the lift bottom support device 13 is further included for fixing
Three semi-rings 1323 of oil cylinder body 1322 and the gland 1324 for fixing three semi-ring 1323 are stated, three semi-ring 1323 wraps
Snap ring body 13231 and annular groove 13232 are included, the diameter of the annular groove 13232 is opposite with the diameter of the piston rod 1321
Should, the babinet 131 be provided with 13231 corresponding second groove of snap ring body, be provided on the gland 1324
The threaded hole 13241 that is threadedly coupled with the babinet 131 and with the 13232 corresponding gland hole 13242 of annular groove, it is described
Three semi-rings 1323 are fixed on by the gland 1324 in second groove.Specifically, the second groove is arranged on the support of lift bottom
The exit of device 13.It is threadedly coupled by gland with babinet, three semi-rings is made to be fixed in the second groove, so as to pass through three semi-rings
Fixed oil cylinder body, prevents oil cylinder body from generating friction with babinet when piston rod is axially moved, reduce oil cylinder body with
Abrasion between babinet.
In one of the embodiments, the hydraulic support further includes to connect the lift bottom support device 13 and described
The connector of pedestal 11.By connector lift bottom support device is enable to be fixedly connected with pedestal.
In one of the embodiments, the connector includes the first shackle 14, the second shackle 15 and round-link chain 16, described
16 one end of round-link chain is connected with first shackle 14, and 16 other end of round-link chain is connected with second shackle 15, described
It is provided on pedestal 11 and is set with 14 corresponding first mounting hole 112 of the first shackle, 1321 other end of piston rod
Have and 15 corresponding second mounting hole 13211 of the second shackle.
Specifically, the second shackle 15 and round-link chain 16 swing back and forth with stretching back and forth for piston rod 1321.Though
So bottom lifting device 13 is designed in the first groove 111 of embedded pedestal 11, piston rod 1321 can be protected, but due to fully mechanized mining work
It is more complicated to make face fan section surface state, when the ground in fully-mechanized mining working fan section becomes hard bottom plate from soft seat suddenly,
Since the moment strength of appearance can cause 1321 flexural deformation of piston rod, pass through the first shackle 14, the second shackle 15 and round-link chain
16 are flexible coupling piston rod 1321 and pedestal 11, and the second shackle 15 and round-link chain 16 play piston rod 1321 buffering and make
With, prevent 1321 flexural deformation of piston rod, preferably protection lift bottom support device 13.
In one of the embodiments, first mounting hole 112 is arranged on to connect the connection of the hydraulic support
The bottom of the connecting plate 18 of bar 17.By the way that the first mounting hole to be arranged on to the bottom of connecting plate, the materials of connector are reduced, are saved
Cost, and lift bottom support device is enable preferably to stretch back and forth in the horizontal direction with pedestal.
In one of the embodiments, it is additionally provided with to strengthen the intensity of first shackle 14 on the pedestal 11
Reinforcing plate 113, described 113 one end of reinforcing plate are connected with first mounting hole 112,113 other end of reinforcing plate with it is described
Pedestal 11 connects.It can strengthen the intensity of the first mounting hole by reinforcing plate, connector is made not allow easy fracture, so as to protect piston
Bar prevents piston rod to be damaged.
The operation principle of the utility model is illustrated below, it is specific as follows：
When the after-frame 20 of hydraulic support supports, and side arm 19 moves forward, manually operation valve control passage very heavy 132 first
Piston rod 1321 is stretched out into oil cylinder body 1322, stretches out lift bottom support device 13, then manually operation valve console again
Bottom very heavy 12 is stretched out, and lifts the support lift of bottom support device 13 bottom very heavy 12 at this time, makes lift bottom very heavy 12 by the whole top upwards of side arm 19
It rises, prevents that pedestal 11 bores happening for floor when side arm 19 from moving forward.
Implement the utility model, by setting the lift bottom support device that lift bottom can be supported very heavy on pedestal, work as hydraulic pressure
It is very heavy by lifting bottom support device lift bottom during the side arm Forward of stent, make side arm is whole to jack up upwards, prevent side arm preceding
Floor is bored during shifting, influences using effect.Meanwhile lift bottom support device is arranged in the first groove of pedestal, support lift bottom
In device insertion pedestal, it is not easily susceptible to damage, it is simple in structure, it is easy to operate.
Above-described is only the principle and preferred embodiment of the utility model.It should be pointed out that for the general of this field
For logical technical staff, on the basis of the utility model principle, several other modifications can also be made, also should be regarded as this practicality
New protection domain.
