Description
Technical field
The utility model relates to load maintainer, particularly a kind of load maintainer for roller service lifetime testing machine.
Background technology
At present, in a lot of plant equipment, all need to install roller, it can be used as a link in kinematic train, also can be used as other purposes.The rotating property of these rollers in plant equipment is often directly connected to transmission efficiency and the stability etc. of kinematic train or the performance of plant equipment is caused to other impact, therefore, before dispatching from the factory, these rollers need its Mechanics Performance Testing and life parameter to test.
But in the equipment of existing pair roller life test, load on or the unloading manner of its load maintainer are more extensive, load on or unloading are by manual control, and automaticity is low, and work efficiency is not high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of load maintainer that can flexibly, accurately realize the roller service lifetime testing machine of the load or unload of load.
For solving the problems of the technologies described above adopted technical scheme: a kind of load maintainer of roller service lifetime testing machine, comprise frame and the loading lever that is horizontally placed on frame top, be provided with the bolster for supporting test roller at described loading lever middle part, described loading lever one end and frame are hinged, the described loading lever other end is provided with adjustable counter balance counterweight, in described frame, be provided with the automatically controlled load regulation mechanism that loads lever in order to hold up or to transfer, on described loading lever, be also provided with load micro-adjusting mechanism.
Further, the controller that described automatically controlled load regulation mechanism comprises sensor, is connected with sensor electrical, and electric pushrod, the pedestal of described electric pushrod is articulated with in frame, the push rod of described electric pushrod is articulated with and loads on lever, and the work of described controller control electric pushrod is to hold up or to put down loading lever.
Further, the push rod of described electric pushrod can regulate along loading lever length direction with the pin joint that loads lever.
Further, the distance between one end and the bolster of described loading lever is less than the distance between the other end and the bolster that loads lever.
Further, described load micro-adjusting mechanism comprises the horizontal fine setting cross bar paralleling with loading lever on loading lever and is located at the fine setting counterweight that can move along fine setting cross bar length direction on fine setting cross bar.
Beneficial effect: in this load maintainer, loading the lever other end makes the roller that loads lever middle part contact with driving wheel by the counterweight that hangs constant weight in the mode of lever pressurization, thereby by automatically controlled load regulation mechanism being set in order to hold up or to transfer the load or unload that loads lever and realize pair roller, automatically controlled load regulation mechanism adopts the test load of the mode pair roller of automatically controlling to regulate in real time; The further fine adjustment load of load micro-adjusting mechanism is also set simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
With reference to Fig. 1, the load maintainer of a kind of roller service lifetime testing machine of the utility model, comprise frame 10 and the loading lever 20 that is horizontally placed on frame 10 tops, be provided with the bolster 21 for supporting test roller at loading lever 20 middle parts, loading lever 20 one end and frame 10 is hinged, load lever 20 other ends and be provided with adjustable counter balance counterweight, in frame 10, be provided with the automatically controlled load regulation mechanism 30 that loads lever in order to hold up or to transfer, be also provided with load micro-adjusting mechanism 40 loading on lever 20.
This load maintainer mainly drives to be arranged on and loads the roller to be tested at lever 20 middle parts and press down it is contacted with the driving wheel 11 of below, and then simulates the use state of roller, and then its mechanical property and life parameter are tested.
Loading lever 20 other ends makes the roller that loads lever 20 middle parts contact with driving wheel 11 by the counterweight that hangs constant weight in the mode of lever pressurization, wherein the loading of load and unloading regulate control by automatically controlled load regulation mechanism 30, load levers 20 when automatically controlled load regulation mechanism 30 holds up, realize the load unloading to roller to be tested; Transfer and load lever 20 when automatically controlled load regulation mechanism 30, realize the load on to roller to be tested.
Distance between one end and the bolster 21 of loading lever 20 is less than the distance between the other end and the bolster 21 that loads lever 20, in the present embodiment, bolster 21 is arranged on and loads lever 20 avris, the approximately position in whole loading lever 1/20th 4 length, thereby when in the time loading lever 20 other ends suspension counterweight, load lever 20 and press down in the mode of lever pressurization.
Wherein, automatically controlled load regulation mechanism 30 comprises sensor, controller and electric pushrod 31, the pedestal of electric pushrod 31 is hinged in frame 10, and the push rod of electric pushrod 31 is hinged in a side that loads the close suspension counterweight of lever 20, the approximately position in whole loading lever 1/20th 4 length, the push rod of electric pushrod 31 can regulate along loading lever 20 length directions with the pin joint that loads lever 20, on loading lever 20, multiple connecting holes are set along its length, the push rod of electric pushrod 31 selects different connecting holes and loading lever 20 to carry out hinged, expand loading range of adjustment with this, by the automatically controlled effect of sensor and controller, electric pushrod 31 can accurately hold up or transfer loading lever 20, thereby accurately realize flexibly load or unload.
Simultaneously, this automatically controlled load regulation mechanism 30 also has the function of Real-Time Monitoring, in the time that the roller test of a certain station damages, because of the excessive trigger sensor of beating, electric pushrod 31 lifts the loading lever 20 of this station, make this station withdraw from test, and do not affect the roller testing experiment of other stations.
This load maintainer also arranges load micro-adjusting mechanism 40 to realize more accurately to fixed load, this load micro-adjusting mechanism 40 comprises the horizontal fine setting cross bar 41 paralleling with loading lever 20 on loading lever 20 and is located at the fine setting counterweight 42 that can move along fine setting cross bar 41 length directions on fine setting cross bar 41, fine setting cross bar 41 is selected screw rod, fine setting counterweight 42 is threaded on fine setting cross bar 41, by moving left and right fine setting counterweight 42, make to load lever 20 and have subtle change near that one end weight of automatically controlled load regulation mechanism 30, thereby making to load lever 20 changes to some extent to the loading force of roller to be tested, to reach the object to load precise fine-adjustment.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make various variations.
