Description
Technical field
The utility model relates to trolley and manufactures field, refers to particularly for verifying that can trolley by keep a kind of trolley walking test machine of normal usage function after some barriers.
Background technology
In the process of walking, can jolt during road surface or barrier by injustice, this jolting likely causes the parts and components on trolley to damage to trolley, affects vehicle and uses.In order to verify whether trolley can keep normal using function after by the barrier of some, needs to carry out walking test; Traditional walking test machine can not simulate normal pedestrian accurately and carry out the situation that trolley clears the jumps, and the analog rate of testing machine and obstacle height generally can not adjust, can not adapt to the testing requirements that the trolley of different model is different, range of application is narrow.
Summary of the invention
The purpose of this utility model be exactly to overcome prior art exist defect, provide a kind of can accurate simulation trolley walking states, can adapt to differing heights trolley different tests require trolley walking test machine.
For achieving the above object, trolley walking test machine designed by the utility model, comprise the frame for laying tested trolley, its special character is: described frame has horizontal supporting seat and coupled vertical fixed frame, described horizontal supporting seat both sides are respectively arranged with initiatively backing roll and driven backing roll, described active backing roll is connected with drive motor by reducer casing, be surrounded with feed belt between described driven backing roll and active backing roll, described feed belt be distributed with test barrier; When trystate, the caster seat of described tested trolley drops on feed belt and coordinates with its rolling, and the handrail of described tested trolley is fixed on vertical fixed frame and limits its tangential movement.
Preferably, the inner side of described driven backing roll is provided with belt tensioning mechanism.Because long walk test can cause feed belt to loosen, the phenomenon of belt slip operationally will be there is time serious, by the spacing of belt tensioning mechanism adjustable initiatively backing roll and driven backing roll, and then the tension force of adjustment feed belt, guarantee test machine normally runs.
Preferably, described test barrier is connected by screw and feed belt are removable.Like this, the height of feed belt loading end can be protruded according to the different test request Adjustment Tests barrier of tested trolley.
Preferably, described drive motor is the buncher of Frequency Converter Control.Due to the simulation of testing machine needs is the situation that pedestrian breaks the barriers with walking speed promotion trolley, therefore controls the speed of drive motor by frequency converter adjustment, and then the rolling speed of control feed belt, as far as possible close to pedestrian walking speed.
Preferably, described vertical fixed frame is the adjustable framework of beam height.Like this, can, according to different model barrow armrest height control beam height, the utility model be made to be suitable for the trolley Traveling simulator test of various model differing heights.
The advantage of the design is: the utility model solves the defect of existing testing machine, there is the features such as structure is simple, simple operation, accurate simulation pedestrian can carry out trolley walking and to clear the jumps state, and by adjustable vertical fixed frame and detachable test barrier, the testing requirements that different model height trolley is different can be adapted to, applied widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model trolley walking test machine.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
In figure: drive motor 1; Reducer casing 2; Feed belt 3; Test barrier 4; Frame 5 (wherein: horizontal supporting seat 5.1, vertical fixed frame 5.2); Belt tensioning mechanism 6; Initiatively backing roll 7; Driven backing roll 8; Tested trolley 9 (wherein: castor 9.1, handrail 9.2); Screw 10; Test load 11.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Trolley walking test machine shown in Fig. 1 ~ 2, comprises the frame 5 for laying tested trolley 9, and frame 5 has horizontal supporting seat 5.1 and coupled vertical fixed frame 5.2, and vertical fixed frame 5.2 is the adjustable framework of beam height.Horizontal supporting seat 5.1 both sides are respectively arranged with initiatively backing roll 7 and driven backing roll 8, initiatively backing roll 7 is connected with drive motor 1 by reducer casing 2, be surrounded with feed belt 3 between driven backing roll 8 and active backing roll 7, feed belt 3 be distributed with test barrier 4; When trystate, the castor 9.1 of tested trolley 9 is located on feed belt 3 and coordinates with its rolling, and the crossbeam that the handrail 9.2 of tested trolley 9 is fixed on vertical fixed frame 5.2 limits its tangential movement.
Tested trolley 9 is mounted with test load 11, the handrail of tested trolley 9 is fixed on the crossbeam of vertical fixed frame 5.2, and drive motor 1 coordinates drive feed belt 3 to run along direction as shown by gear train and reducer casing 2.Tested trolley 9 does relative motion with feed belt 3, in operational process, each castor 9.1 is successively by being arranged on the test barrier 4 on feed belt 3, and simulated operator promotes the situation of trolley through uneven road surface, and drive motor 1 is the buncher of Frequency Converter Control.Due to the simulation of test machine needs is the situation that pedestrian breaks the barriers with walking speed promotion trolley, therefore the speed of drive motor 1 is controlled by frequency converter adjustment, and then control the rolling speed of feed belt 3, as far as possible close to pedestrian walking speed, in the design, the travelling speed of feed belt is 2.8 ~ 4.5km/h.
In test, tested trolley 9 needs to arrange according to test by the quantity and travel speed testing barrier 4, the time and testing machine continuous working period of testing and needing to carry out can be calculated thus, control time accordingly in setup control circuit on the time relay, when test proceeds to official hour, test stops automatically.
When the model of tested trolley 9 changes, its handrail 9.2, castor 9.1 diameter also change thereupon, and therefore, the beam height of the test height of barrier 4 and the vertical fixed frame 5.2 of fixed armrest 9.2 also needs to change thereupon; In order to meet this demand, test barrier 4 in this novel practical for detachable fixing; Every only test barrier 4 two screws 10 are fixed on feed belt 3, unclamp screw 10 and can take off original test barrier 4, select the test barrier 4 of proper height according to test condition after, with screw 10, test barrier 4 is fixed on feed belt 3.
After long-time use, feed belt 3 can loosen, and skidding can occur time serious in operational process, causes actual speed lower than setting speed.In this novel practical, the inner side of driven backing roll 8 is provided with belt tensioning mechanism 6.By the spacing of the driven backing roll 8 of adjustable in belt tensioning mechanism 6 with active backing roll 7, and then the tension force of adjustment feed belt 3, ensure that test machine normally runs.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
