The left side on 1 top of cabinet is arranged in platform 3;Two support rods 6 are disposed side by side on the left side on 1 top of cabinet, and position
In the two sides at 3 middle part of workbench;The lower lock block 5 is slidably mounted on two support rods 6 and is located at 3 top of workbench, institute
It states and is set on the left of 1 lower part of cabinet there are two oil cylinder 7, the piston rod of the oil cylinder 7 protrudes into the rear and pushing in the support rod 6
One end of block 5 is connected, and the notch 61 slided up and down convenient for the lower lock block 5 is offered on the support rod 6;The placement block 4
It is mounted on workbench 3;The placement block 4 includes the first placement block 41 and second places block 42, and described first places 41 He of block
Second places block 42 can the opposite or opposite sliding on workbench 3.Using the equipment do it is anti-reckon the actual amount after a discount test when, make the first placement block 41
Suitable spaced position is slided on the contrary with the second placement block 42, and one end of cement briquette 8 is made to be placed on the first placement block later
On 41, the other end is placed on the second placement block 42, and the piston rod contraction of oil cylinder 7 declines lower lock block and oppresses cement briquette 8
It completes anti-reckon the actual amount after a discount to test, after completing experiment, the piston rod of oil cylinder 7 makees extensional motion to reset.When doing crush test using the equipment,
It slides in opposition the first placement block 41 and the second placement block 42 to closed position, is later placed into cement briquette 8 after closing up
Placement block 4 on, the contraction of the piston rod of oil cylinder 7 decline lower lock block and oppresses cement briquette 8 to complete crush test, completes to test
Afterwards, the piston rod of oil cylinder 7 makees extensional motion to reset.
As further improvement of these options, the workbench 3 includes Bidirectional-screw 31, sliding rail 32 and motor 33;
The Bidirectional-screw 31 is mounted on 3 middle part of workbench, and is connected with the first placement block 41 and the second placement block 42;Institute
The upper surface that sliding rail 32 is mounted on the workbench 3 is stated, and is slidably connected with the first placement block 41 and the second placement block 42;
The motor 33 is connected with the transmission of Bidirectional-screw 31.Specifically, the screw thread half of the wire rod thread part of the Bidirectional-screw 31
Left hand thread, the other half is right-handed thread, it is described first placement block 41 connect with left hand thread, it is described second placement block 42 and
Right-handed thread connection.Bidirectional-screw 31 is imparted power to by the positive and negative rotation of motor 33, so that 41 He of block is placed in driving first
Second places block 42 slides in opposite directions or on the contrary.
As further improvement of these options, the baffle 34 of protection Bidirectional-screw 31 is additionally provided on the workbench 3,
Prevent from making it is anti-reckon the actual amount after a discount cement briquette 8 when testing fracture fall after injure Bidirectional-screw 31 by a crashing object.Do anti-reckon the actual amount after a discount when testing, it is preferred that in cement
One layer of cloth is spread at the lower section sliding rail 32 of test block 8, the sliding rail 32 that lower section exposes is completely covered in cloth, with the examination of easy cleaning cement
Block 8 fracture after detritus.
As further improvement of these options, the lower lock block 5 includes crossbeam 51, pressure sensor 52 and lower platen
53;51 both ends of crossbeam are connected with the piston rod of two oil cylinders 7 respectively;The lower platen 53 is mounted on the crossbeam 51
Lower section;The pressure sensor 52 is mounted between the crossbeam 51 and the lower platen 53.Lower lock block 5 is realized by oil cylinder 7
Slide up and down, while moving stable characteristic using oil cylinder 7 makes stress when experiment tend to constant, and it is quasi- to pass through pressure sensor 52
True measured pressure value.
As further improvement of these options, lower press strip 54, the lower press strip 54 are additionally provided on the lower platen 53
The lower surface of lower platen 53 is embeddedly set;53 lower surface of lower platen is equipped with the groove being adapted with lower press strip 54
56;The push rod 55 for pushing lower press strip 54 to stretch out is additionally provided with inside the lower platen 53.Specifically, the thickness of the lower press strip 54
The deep equality of degree and groove 56, that is, when press strip 54 being played to be recovered in lower platen 53 under the action of push rod 55, lower press strip 54
Lower surface is concordant with the lower surface of lower platen 53.Do it is anti-reckon the actual amount after a discount when testing, push rod 55 pushes lower press strip 54 to make it beyond lower platen 53
Lower surface resets 52 numerical value of pressure sensor later, places block 41 and second in lower press strip 54, first later and places block 42 jointly
Effect is lower to be completed to resist to reckon the actual amount after a discount to test;When doing crush test, press strip 54 makes the following table on its small surface and lower platen 53 under push rod 55 pulls
Face is concordant, resets 52 numerical value of pressure sensor later, places block 41 and second in lower platen 53, first later and places block 42 jointly
Effect is lower to complete crush test.
As further improvement of these options, the top of two support rods 6 is equipped with described in dismountable prevent
The fixing piece 62 that lower lock block 5 is surprisingly deviate from.Since lower lock block 5 is often crimped with cement briquette 8, and when crimping due under
The dynamics that briquetting 5 pushes is larger, so that the interaction force between lower lock block 5 and cement briquette 8 is also larger, therefore, through too long
After the use of time, lower lock block 5 can be worn.Remove the i.e. conveniently replaced lower lock block 5 of fixing piece 62.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations;To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement;And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
