Utility model content
Because national examination criteria regulation test height is that sand hill bottom surface is to network plane distance, give in the measurement of test height and brought certain difficulty, and the net test height of different model is also different, the utility model object is to provide a kind of aloft work protection network impact resistance proving installation, so that can carry out impact resistance test under different shock height conditions to different aloft work protection network samples.
For achieving the above object, design of the present utility model is: the utility model comprises aloft work protection network test stand, range sensor, sensing station are adjusted slide unit, chucking position is adjusted slide unit, clamped handgrip, wire rope and reel, control panel and display, have following function:
1), described range sensor angle adjustable, by adjusting the angle of sensor, the true altitude that can accurately calculate weight position and net is poor.
2), described range sensor position adjustment can by Manual-pushing sensing station adjust slide unit on cross slide way 1, horizontally slip, can make range sensor carry out data acquisition in different positions, whole device is positioned at the edge of test stand, in order to avoid after try net destruction, test weight falls to smashing instrument.
3), there are two motors above-mentioned chucking position adjusting gear inside, the motion of a whole device of Electric Machine Control, make device horizontal moving left and right on cross slide way 2, the effect of another motor is transferring and upper receipts by the rotating control rope of motor, cylinder is connected with motor by gear drive, control panel, by the work of two motors of controlled in wireless mode control, can make weight arrive assigned address.
4), described clamping handgrip is the automation handgrip of the German SOMMER AUTOMATIC GP1816NC-BT of company model, can control handgrip Automatic-clamping and unclamp weight, described fixture is connected on rope.
5), described control panel and display be fixed in detector location and adjust on slide unit, control panel is for controlling the position of fixture and release and the crawl of control weight, display is for showing the difference in height of weight and aloft work protection network, and automatically calculating in conjunction with the weighing scale of weight the maximum impact force that aloft work protection network can bear, above-mentioned control panel is by the motion of control device of wireless control chucking position adjusting gear and the motion of clamp device.
According to above-mentioned utility model design, the utility model adopts following technical proposals: a kind of aloft work protection network impact resistance proving installation, comprise aloft work protection network test stand, range sensor, sensing station is adjusted slide unit, chucking position is adjusted slide unit, clamp handgrip, display, wire rope and reel, it is characterized in that: aloft work protection network test stand fixes on the ground, tested aloft work protection network hangs on the hook on test stand, sensing station adjustment slide unit is slidably mounted on a cross slide way 1 of test stand below, range sensor and display screen are fixed by screws in detector location and adjust slide unit top, chucking position is adjusted slide unit and is slidably mounted on by inner slide block on a cross slide way 2 of test stand top, reel is fixedly connected on chucking position by screw and adjusts on slide unit, wirerope-winding is on reel, clamp one end that handgrip is fixedly connected on wire rope.
Described aloft work protection network test stand is the square framework being welded by shaped steel, and cross slide way 1 is welded on the below of framework, and cross slide way 2 is welded on the centre of framework end face.
Described clamping handgrip is the automation handgrip of the German SOMMER AUTOMATIC company GP1816NC-BT model of producing.
The utility model compared with prior art, there is following apparent feature and remarkable advantage: this device has simple to operate, flexibly, accurately and reliably, alleviate testing staff's workload, can realize in different positions and differing heights and testing, can more comprehensively detect aloft work protection network performance.
Embodiment
A preferred embodiment accompanying drawings of the present utility model is as follows:
Embodiment mono-:
Referring to figure (1) and figure (2), this aloft work protection network impact resistance proving installation, comprise aloft work protection network test stand (2), range sensor (4), sensing station are adjusted slide unit (3), chucking position is adjusted slide unit (9), clamped handgrip (10), wire rope (8) and reel (7), control panel (13) and display (12).
Aloft work protection network test stand (2) fixes on the ground, tested aloft work protection network (5) hangs on the hook (11) on test stand (2), sensing station adjustment slide unit (3) is slidably mounted on the cross slide way 1(14 of test stand (2) below) on, range sensor (4), control panel (13) and display screen (12) are fixed by screws in detector location and adjust slide unit (3) top, chucking position is adjusted slide unit (9) and is slidably mounted on the cross slide way 2(6 above test stand (2) by inner slide block) on, reel (7) is fixedly connected on chucking position by screw and adjusts slide unit (9), wire rope (8) is wrapped on reel (7), clamp one end that handgrip (10) is fixedly connected on wire rope (8).
Embodiment bis-:
With reference to Fig. 1 and Fig. 2, the present embodiment and embodiment mono-are basic identical, and special feature is as follows:
Described aloft work protection network test stand (2) is the square framework being welded by shaped steel, cross slide way 1(14) be welded on the below of framework, cross slide way 2(6) be welded on the centre of framework end face.
Described clamping handgrip (10) is the automation handgrip of the German SOMMER AUTOMATIC company GP1816NC-BT model of producing.
The principle of work of this device:
The hook (12) that aloft work protection network (5) is hung over to test stand (2) is upper, presses the total power switch on control panel (13), whole proving installation is obtained electric.Control top chucking position by control panel (13) and adjust the movement of slide unit (9) and the motion of reel (7), making to clamp handgrip (10) drops to after assigned address clamping sand hill (1), again by sand hill (1) lifting, and move to test landing point directly over.Adjust range sensor (4) to optimum position, measure the difference in height of sand hill (1) and aloft work protection network (5) plane, according to the height number of the upper sand hill (1) of display screen (12), will try the specified altitude assignment that sand hill (1) is adjusted to.Arrive after assigned address, control panel (13) clamps handgrip (10) transmission instruction by radioing to, make to clamp handgrip (10) and unclamp sand hill (1), aloft work protection network (5) is impacted in sand hill (1) free-falling under Action of Gravity Field, and then can the firmness after test weight falls and security performance detection to aloft work protection network (5).In addition, capable of regulating sand hill (1) is to other positions, and the landing point of change sand hill (1), tests the impact resistance of aloft work protection network (5) diverse location, thereby can more comprehensively react the performance of aloft work protection network (5).
