Description
Technical field
The present invention relates to a kind of composition system of pressure testing machine, be specifically related to a kind of corner test device of pressure testing machine, belong to engineering testing equipment technical field.
Background technology
The pressure testing machine of prior art refers to shown in Figure of description 1, and it is made up of a few parts such as upper loading plate 1 ', lower loading plate 2 ' and bases 3 '.
Above-mentioned pressure testing machine can only do the detection of vertical mechanical property to test specimen.But the corner test for bridge pad lacks corresponding device, this type of test in the past all needs to rely on special test stand to have assisted.And due to test stand and testing machine can not reliably anchoring, therefore, bring potential safety hazard can at the trial test specimen and operating personnel; Meanwhile, during test, the applying of corner power is also cumbersome.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of corner test device with structure improved pressure testing machine, to overcome described defect of the prior art.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of can to the corner test device of the pressure testing machine that the corner performance of bridge pad is tested, this corner test device can simulate bridge pad in actual use due to rotation that the various factors such as the temperature difference, dynamic load causes, thus whether the corner performance of checking bridge pad meets the Expected Results of design, short form test program simultaneously, improves the security of test.
For achieving the above object, the technical scheme that the present invention takes is: a kind of corner test device of pressure testing machine, and it comprises base, screw mandrel, upper loading plate, lower loading plate, master cylinder, hydraulic top, load sensor, detachable length extension bar and rotary corner plate; Wherein, described screw mandrel is vertically installed on the top of base; Described upper loading plate is arranged on also can along screw mandrel oscilaltion on screw mandrel, and itself and lower loading plate are oppositely arranged; Described master cylinder is immobilizated on base; Described hydraulic top is installed on the side of base, and its top is provided with described load sensor and detachable length extension bar successively; Described rotary corner plate is between upper loading plate and lower loading plate, and detachable length extension bar is positioned at the below of this rotary corner plate one end.
The corner test device of pressure testing machine of the present invention is set to further: on described base, be provided with a guide rail further; Be provided with some pulleys bottom described lower loading plate, these pulleys can along slide.
The corner test device of pressure testing machine of the present invention is also set to: described rotary corner plate is that decussate texture is arranged.
Compared with prior art, the present invention has following beneficial effect: the corner test device structure of pressure testing machine of the present invention is simple, and it can be tested the corner performance of bridge pad, meanwhile, simplifies the program of test, improves the security of test.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the pressure testing machine of prior art.
Fig. 2 is the structural representation of the corner test device of pressure testing machine of the present invention.
Fig. 3 is the vertical view of the corner test device of pressure testing machine of the present invention.
Embodiment
Refer to shown in Figure of description 2 and accompanying drawing 3, the present invention is a kind of corner test device of pressure testing machine, it is for testing the corner performance of test specimen 10, and it is made up of a few parts such as base 1, screw mandrel 2, upper loading plate 3, lower loading plate 4, master cylinder 5, hydraulic top 6, load sensor 7, detachable length extension bar 8 and rotary corner plates 9.
Wherein, described screw mandrel 2 is vertically installed on the top of base 1.Described master cylinder 5 is immobilizated on base 1, and it can drive loading plate 3 oscilaltion.A guide rail 11 is provided with further on described base.
Described upper loading plate 3 is arranged on screw mandrel 2 also along screw mandrel 2 oscilaltion, thus can apply the certain vertical load of test specimen 10.On this, loading plate 3 and lower loading plate 4 are oppositely arranged.
Be provided with some pulleys 41 bottom described lower loading plate 4, these pulleys 41 can slide along guide rail 11, thus test specimen 10 and rotary corner plate 9 can be sent to immediately below upper loading plate 3.
Described hydraulic top 6 is installed on the side of base 1, and its top is provided with described load sensor 7 and detachable length extension bar 8 successively.This hydraulic top 6 can be supported detachable length extension bar 8 and move straight up.The corner power that described load sensor 7 produces for detecting hydraulic top 6.
Described rotary corner plate 9 is between upper loading plate 3 and lower loading plate 4, and it is that decussate texture is arranged.Described detachable length extension bar 8 is positioned at the below of this rotary corner plate 9 one end.
The principle of work of the corner test device of pressure testing machine of the present invention is as follows: centre rotary corner plate 9 being placed on two test specimens 10, the axis of upper and lower test specimen 10 and rotary corner plate 9 pairs of corner test device; Start master cylinder 5 to test specimen 10 with Vertical Design bearing capacity, then primer fluid bears down on one 6, hydraulic top 6 is upwards after jack-up, by detachable length extension bar 8, test force is passed to rotary corner plate 9, rotary corner plate about 9 is rotated, the actual rotational angle stressing conditions of test specimen 10 under design load effect, thus obtain the true corner performance of test specimen 10.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
