Description
Technical field
The utility model relates to a kind of composition system of pressure testing machine, is specifically related to a kind of corner test unit of pressure testing machine, belongs to the engineering test equipment technical field.
Background technology
The pressure testing machine of prior art sees also shown in the Figure of description 1, and it is by last loading plate 1 ', several parts such as loading plate 2 ' and base 3 ' are formed down.
Above-mentioned pressure testing machine can only be made vertical mechanics performance detection to test specimen.Yet, lacking corresponding device thereof for the corner test of bridge pad, this type of test in the past all need rely on special test stand to assist completion.And because therefore test stand and reliably anchoring of testing machine, bring potential safety hazard can at the trial test specimen and operating personnel; Simultaneously, during test corner power apply also cumbersome.
Therefore, for solving the problems of the technologies described above, necessary a kind of corner test unit with structure improved pressure testing machine is provided, to overcome said defective of the prior art.
The utility model content
For addressing the above problem; The purpose of the utility model is to provide a kind of corner test unit of the pressure testing machine that can test the corner performance of bridge pad; This corner test unit can be simulated bridge pad in actual use because the rotation that various factorss such as the temperature difference, dynamic load cause; Thereby whether the corner performance of checking bridge pad meets the Expected Results of design, and the short form test program improves the security of testing simultaneously.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: a kind of corner test unit of pressure testing machine, and it comprises base, screw mandrel, last loading plate, following loading plate, master cylinder, ram, load sensor, detachable extension rod and rotary corner plate; Wherein, said screw mandrel vertically is installed on the top of base; Said upward loading plate is arranged on also can be along the screw mandrel oscilaltion on the screw mandrel, and it is oppositely arranged with following loading plate; Said master cylinder is immobilizated on the base; Said ram is installed on a side of base, and its top is equipped with said load sensor and detachable extension rod successively; Said rotary corner plate is between last loading plate and following loading plate, and detachable extension rod is positioned at the below of this rotary corner plate one end.
The corner test unit of the pressure testing machine of the utility model further is set to: on said base, further be provided with a guide rail; Said loading plate down bottom is provided with some pulleys, and these pulleys can slide along guide rail.
The corner test unit of the pressure testing machine of the utility model also is set to: said rotary corner plate is the decussate texture setting.
Compared with prior art; The utlity model has following beneficial effect: the corner test unit of the pressure testing machine of the utility model is simple in structure, and it can be tested the corner performance of bridge pad, simultaneously; Simplify the program of test, improved the security of test.
Description of drawings
Fig. 1 is the synoptic diagram of the pressure testing machine of prior art.
Fig. 2 is the structural representation of corner test unit of the pressure testing machine of the utility model.
Fig. 3 is the vertical view of corner test unit of the pressure testing machine of the utility model.
Embodiment
See also Figure of description 2 with shown in the accompanying drawing 3; The utility model is a kind of corner test unit of pressure testing machine; It is used to test the corner performance of test specimen 10, and it is made up of several parts such as base 1, screw mandrel 2, last loading plate 3, following loading plate 4, master cylinder 5, ram 6, load sensor 7, detachable extension rod 8 and rotary corner plates 9.
Wherein, said screw mandrel 2 vertically is installed on the top of base 1.Said master cylinder 5 is immobilizated on the base 1, and it can drive loading plate 3 oscilaltions.On said base, further be provided with a guide rail 11.
Saidly go up that loading plate 3 is arranged on the screw mandrel 2 and can be, thereby can apply the certain vertical load of test specimen 10 along screw mandrel 2 oscilaltions.Should go up loading plate 3 is oppositely arranged with following loading plate 4.
Said down loading plate 4 bottoms are provided with some pulleys 41, and these pulleys 41 can slide along guide rail 11, thus can with test specimen 10 and rotary corner plate 9 be sent to loading plate 3 under.
Said ram 6 is installed on a side of base 1, and its top is equipped with said load sensor 7 and detachable extension rod 8 successively.This ram 6 can be replaced detachable extension rod 8 and move straight up.Said load sensor 7 is used to detect the corner power that ram 6 produces.
Said rotary corner plate 9 is between last loading plate 3 and following loading plate 4, and it is the decussate texture setting.Said detachable extension rod 8 is positioned at the below of these rotary corner plate 9 one ends.
The principle of work of the corner test unit of the pressure testing machine of the utility model is following: rotary corner plate 9 is placed on the centre of two test specimens 10, up and down the axis of test specimen 10 and 9 pairs of corner test units of rotary corner plate; Starting master cylinder 5 gives test specimen 10 with vertical design bearing capacity; Primer fluid bears down on one 6 then; Ram 6 upwards after the jack-up, passes to rotary corner plate 9 through detachable extension rod 8 with test power, makes rotary corner plate 9 do to rotate up and down; The actual rotational angle stressing conditions of test specimen 10 under the design load effect, thus test specimen 10 true corner performances obtained.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
