Embodiment
Referring to Fig. 1 and Fig. 2, the present invention is a kind of detection testing equipment of vertical transportation machinery safety guard, and it is equipped with anti-falling safety device and detects testing table, and this detects testing table and partly is made up of cage 1, driving mechanism 2, safety test stand 3 and guide rail bracket 4 etc.
Referring to Fig. 3, cage 1 base plate is provided with balancing weight 7 mounting holes, and the position and the geomery of this mounting hole and balancing weight 7 adapt, and can be the rectangle square hole.Shelve the crossbeam 9 of supporting balancing weight 7 on the reinforcement bearing of cage 1 base plate, the balancing weight 7 that is positioned at crossbeam 9 tops is along with cage moves together.Balancing weight 7 is the stepped rectangle balancing weight 7 of its two end, and balancing weight piles up and forms, and is connected by register pin 8 between each balancing weight 7.Cage 1 drives crossbeam 9 tops when rising balancing weight 7 moves together, realizes loading.
On safety installation base plate, be provided with a plurality of safeties stations are installed, can be used for the test of the safety of various different models and installation dimension.Safety is installed on the base plate preparation safety is housed, and to prevent that detected safety is malfunctioning the cage accident takes place to weigh down.
The rotary encoder 10 of induction cage 1 position is housed, to the analysis of rotary encoder 10 signals, responsiveness, braking distance and the braking acceleration that calculating can draw safety on the high speed shaft of driving mechanism 2.These parameters are gathered with the robot calculator of capture card automatically by band A/D conversion, and data are analyzed automatically by special software, and examining report is generated automatically by robot calculator.
Detect testing table the operating console that integrates operation, demonstration, control function is housed, operating console is succinct, attractive in appearance, meets the designing requirement of ergonomics.Be provided with two drop shutter test buttons on operating console, have only when two buttons are pressed simultaneously, the drop shutter test order just can come into force.
Adopt the detection testing equipment of vertical transportation machinery safety guard of the present invention; the gear type construction hoist falling-proof safety is detected; according to the requirement of technical standard JG121-2000 " building hoist cone of gears cydariform gradual anti-falling safety device ", safety detects needs the parameter of control to be mainly brake load, retro-speed and braking distance.The method of the test stand test in the detection testing equipment operation technique standard of the present invention has been finished the measurement of specified data.
1, the enforcement of process of the test: the operating console button on the operation detection testing table, discharge the detent of driving mechanism 2, cage 1 drives 3 tenesmus of safety test stand by pin type sensor 6, when tenesmus speed reaches the safety responsiveness, safety is braked test stand 3 and cage 1 on guide rail bracket 4, finishes process of the test.
2, the adjusting of safety test load: the size of safety test load is regulated with size rectangle balancing weight 7 identical, that its two end has the ladder breach by shape, be connected by register pin 8 between each balancing weight 7, guaranteed that balancing weight does not misplace after superimposed.After cage 1 descended, balancing weight 7 entered cage inside by set mounting hole on cage 1 base plate, and crossbeam 9 two ends that will be used to support balancing weight 7 are shelved on the reinforcement bearing of cage 1 base plate, and the balancing weight 7 that is positioned at crossbeam 9 tops is along with cage moves together.By adjusting the quantity of crossbeam 9 top balancing weights 7, can regulate the size of safety test load.
3, the measurement of test parameters:, can obtain the size of safety test loaded load and the maximum impact load in the safety process of the test by reading the signal of the pin type sensor 6 that connects cage 1 and safety test stand 3.The rotary encoder 10 that has reflected cage 1 position is installed, to the analysis of rotary encoder 10 signals, responsiveness, braking distance and the braking acceleration that calculating can draw safety on the high speed shaft of driving mechanism 2.
4, testing process data automatic collecting and control: pin type sensor 6, rotary encoder 10 signals are handled, analyze, are calculated the back by robot calculator and generate examining report automatically after treatment, export automatically by printer.
5, the safeguard protection of process of the test: this detection testing table has following maltilevel security defencive function:
(1) on the safety test stand 3 except detected safety 5 is housed, protection safety 11 also is housed, the action when detected safety 5 is malfunctioning of protection safety 11 prevents the detection accident.
(2) between safety test stand 3 and the cage 1 except having pin type sensor 6 is connected, protection key 12 also is housed, just in case 6 fractures of pin type sensor, protection key 12 can prevent cage 1 tenesmus.
(3) signal of rotary encoder 10 has reflected the position of cage 1, and robot calculator can be by relatively controlling the position of cage 1 to the analysis of rotary encoder 10 signals, prevents that the cage operation from surmounting predetermined stroke and have an accident.
(4) in order to prevent maloperation, on the control panel of operating console, be provided with two safety drop shutter test buttons, have only when two buttons are pressed simultaneously, just experimental order can come into force.
Detection pilot system of the present invention adopts independently developed software systems, comprises modules such as operation interface module, data acquisition, processing module and database, realizes that automatic processing, the examining report of detection data printed and the active data management automatically.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention variation, the modification of the foregoing description.
