Description
Technical field
The utility model relates to the falling test stand technical field, is specifically related to a kind of novel lifting gear in the large-scale falling test stand.
Background technology
Falling test stand is a kind of dynamic environmental test equipment, main analog equipment package issuable falling and shock environment in the actual shipment cargo handling process, thereby the examination product package bears vertical dropping shock in transportation and handling procedure ability.This testing equipment is widely used in industries such as household electrical appliances, electronics, instrument and meter, communication.
Falling test stand mainly is made of base plate, work support arm, column and hoisting gear, lock release, controller etc., and large-scale falling test stand also increases the vibration reduction and cushioning device.Falling test stand must be promoted to setting height with test specimen by hoisting gear, discharges under the test specimen stationary state then, makes that test specimen is vertical freely to be fallen, and so just can finish the fall-down test process.Wherein, column and hoisting gear are fixed on the base plate, and its major function is that the test product that drives on support arm and the support arm moves up and down together, no matter adopts what method to promote, and hoisting gear must guarantee that motion is steady, hoisting depth is accurate.
The method for improving that falling test stand adopts in the prior art is that one-sided column chain promotes or one-sided column hydraulic pressure lift, and support arm only has a side to be connected with hoisting gear.The characteristics of this method for improving are that test product and support arm only have one to promote stress point, discharge back arm and also have only a buffering stress point, and power all act on the root of support arm, so discontinuity, the dynamic balance of support arm is poor.This can cause promoting that stationarity is poor, support arm constantly be subjected to single external force effect produce inevitably distortion cause short and maintenance difficult in serviceable life of falling test stand, the efficient of falling low, fall problems such as noise is huge.And adopt long wide that this kind method for improving support arm can not design, cause the volume and weight that promotes test product limited, be difficult to finish whole faces, rib, the angle fall-down test of heavy packages part (it is generally acknowledged that weight surpasses the package of 1200mm * 1200mm * 1200mm greater than 150kg or package full-size).Though, the fall-down test device that has adopts the two guide rail structures of one-sided column to improve the stability of lifting, perhaps adopt hydraulic cylinder to improve lifting force, but two guide rails and hydraulic cylinder all are in a side concurrent working, stressing conditions does not change, though this structure can improve the stability of hoisting gear operation to a certain extent, still can't finish fall-down test for big quality and large-sized laboratory sample.
The utility model content
The utility model provides a kind of lifting gear of falling test stand of reasonable in design, it adopts bilateral air pressure to drive or bilateral driven by servomotor hoisting gear, its objective is guarantee that lifting process is steadily reliable, support arm is stressed evenly, highly the location accurate, fall efficient height, noise little, exempt from ground, easy to maintenance, thereby satisfy the fall-down test requirement of heavy packages part.
For realizing above-mentioned utility model purpose, the technical scheme that the utility model adopted is: a kind of lifting gear of falling test stand, and it is installed on the falling test stand, and this novel lifting gear comprises a crossbeam portion, the pair of raising mechanism that is connected with the assembling of crossbeam portion two ends, and lifting driving mechanism; Described hoisting gear rises synchronously under the drive that promotes driving mechanism or descends.
Described hoisting gear is provided with linear bearing, and described falling test stand has a column, and this linear bearing is slidingly connected mutually with guide rail on the column that is arranged at described falling test stand.
The two ends of described crossbeam portion are connected with described hoisting gear upper end by a raising rod assembly respectively, and this raising rod assembly is located on the column of described falling test stand.
Described hoisting gear comprises a rigid bodies, and the rigid bodies middle part is vertically arranged with a cavity.
Also be provided with hub lock releasing on the rigid bodies of described hoisting gear, this hub lock releasing is a pneumatic pumping pin, and it comprises backing pin, installs the backing pin guide way of this backing pin, and the driving cylinder that connects with this backing pin guide way.
Described lifting driving mechanism adopts air pressure to promote driving mechanism or servomotor promotes driving mechanism.
Described air pressure promotes and drives is to drive hoisting gear by vertical distribution synchronously in the cylinder of the tight function of strap clamp of column both sides to move up and down.
Described servomotor promotes driving mechanism and comprises the servomotor of being located on the described column, and the leading screw that links to each other with this servomotor, and this servomotor can drive the leading screw rotation, and then is moved up and down by the described hoisting gear of the synchronous drive of leading screw.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
1, because the utility model lifting gear adopts the hoisting gear that is symmetrically set in crossbeam portion two ends, can guarantee the synchronous operation of two hoisting gears, eliminate the transversely deforming of two heel posts again, and test product easy to setup.
2, because promoting driving mechanism, the utility model both sides adopt air pressure to promote driving mechanism or servomotor lifting driving mechanism, hoisting gear slides on guide rail by linear bearing, the life-span and the reliability of lifting process are improved greatly, and highly the location is very accurate, and maintaining is also very convenient.
3, because two hoisting gears of the utility model lifting gear are located at the both sides of a column, make support arm two ends force balance, support arm slides up and down steadily, reliable, reduced the external force damage of support arm greatly, that so just support arm can be done is very wide, very long, therefore, can finish drop test large-scale even the ultra-large type package.
4, because the utility model has reduced the external force damage of support arm greatly, therefore the weight of support arm is alleviated greatly, each fall-down test, support arm falls along two side rails free skatings, the vibration damper that symmetria bilateralis distributes makes soft slow the stopping of support arm, thereby greatly reduce bump vibration and fall-down test noise, and do not need to do foundation special ground.
