Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Fig. 3 is the lifting constitutional diagram of test.
Fig. 4 is the done state figure of test.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, the utility model comprises frame 13, and frame 13 is a shape, and hoisting frame 6 is hung on the crossbeam of frame 13 by hanging wire rope 11, and hoisting frame 6 belows are connected with slinging beam 5, and slinging beam 5 is provided with the steel wire tightrope 4 of lifting electric welding machine.Hoisting frame 6 tops are connected with armature 7, the both sides of armature 7 are provided with guide pole 10, hoisting board 9 is slidably mounted on guide pole 10, the below of hoisting board 9 is connected with the strong electromagnet 8 that coordinates with armature 7, hoisting board 9 is by haulage cable 14 connecting hoisting devices of the pulley 15 of walking around frame 13 tops, boom hoisting is windlass, is made of elevator roller 22, speed reduction unit 23 and motor 21.Haulage cable 14 is provided with pulling block 17, the column of frame 13 is provided with guide plate 16, and upper stroke switch 18 and lower stroke switch 20 are arranged on guide plate 16, and slide block 19 is slidably mounted on guide plate 16, slide block 19 connects pulling block 17, and slide block 19 is promoted to move up and down along guide plate 16 by pulling block 17.
Before beginning test, as Fig. 1, detected electric welding machine 2 use transportation equipments (as forklift) are placed on cushion block 1, with steel wire tightrope 4, (suspension ring) 3 of the lifting gear on electric welding machine are connected and tighten up with slinging beam 5 on testing equipment.At this moment, armature 7 adhesives on strong electromagnet 8 and hoisting frame 6.begin test, as Fig. 2, connect the power supply of strong electromagnet 8, make strong electromagnet 8 and armature 7 adhesives, starter motor 21 drives 22 rotations of elevator roller by speed reduction unit 23, pulling traction steel wire 14 to walk around pulley 15 upwards promotes hoisting board 9, because strong electromagnet 8 is mounted on hoisting board 9, armature 7 is mounted on hoisting frame 6, slinging beam 5 is fixed in again on hoisting frame 6, so, just electric welding machine 2 is lifted to the height of a setting, move-out cushion block 1, steel wire tightrope 4 is stressed to be tightened, hang wire rope 11 lax, on haulage cable 14, shifting block 17 can make slide block 19 move up along guide plate 16, in lifting process, slide block 19 touches lower stroke switch 20 and sends signal, make strong electromagnet 8 dead electricity, armature 7 is thrown off, so, hoisting frame 6 and slinging beam 5 are together with electric welding machine 2 free-falling rapidly under action of gravitation, wire rope 11 is stressed to be tightened until hang, electric welding machine is in suspension status, as shown in Figure 3, make lifting gear (suspension ring) 3 on electric welding machine stand the impact of free-falling, completed single test.Then, motor 21 counter-rotatings, drive 22 counter-rotatings of elevator roller, under the effect of haulage cable 14, strong electromagnet 8 descends along guide pole 10 with hoisting board 9 and contacts with armature 7, and shifting block 17 moves to the position of upper stroke switch 18 with movable slider 19 simultaneously, touch upper stroke switch 18 and send signal, make strong electromagnet 8 energisings, with armature 7 adhesives, can carry out test cycle next time.Stroke, is fallen at lifting controllable in the position of upper stroke switch 18 and lower stroke switch 20.
