Abstract
The invention provides a small-size security crane provided with a travel switch. The small-size crane consists of a motor, a worm gear reducer, a rope rolling rotary drum, a steel wire rope and a lifting hook, wherein a movable cantilever is arranged on a main root of a bracket and the lifting hook is controlled to ascend and descend according to a double-direction switch. A contactor, an automatic resetting normally-opened button and a normally-closed travel switch are connected in front of the single-phase motor and the double-direction switch. The travel switch is fixed on an iron plate of the cantilever, the steel wire rope passes through a cylindrical iron block, and the lifting iron block can impact the travel switch provided with an impact rod. According to the crane with the travel switch, an accident that the lifting hook lifts over the top end of the cantilever cannot occur, so that the traditional crane is modified simply and conveniently.
Description
Technical field
The present invention relates to a kind of hanging device for building, relate generally to a kind of small-sized safe loop wheel machine.
Background technology
At present all use small-sized loop wheel machine in family or the unskilled labourer ground building, small-sized loop wheel machine structure have variedly, using many patterns is appearance patent loop wheel machine (patent No. 200730144078.1).Small-sized loop wheel machine is by electrical motor, worm reducer, serving cylinder, steel rope, and suspension hook, support main root are provided with a mobilizable cantilever, the up-down of two-direction switch control suspension hook.Loop wheel machine operating personnel in actual use can be slipped up and suspension hook is risen and excessively surpassed the cantilever top, makes operating personnel meet accident danger or damage product.
Summary of the invention
In operating process, make a fault sometimes and make suspension hook surpass the deficiency on cantilever top in order to overcome small-sized loop wheel machine; The present invention provides a kind of small-sized safe loop wheel machine that travel switch is housed; This small-sized loop wheel machine promotes the travel switch of cantilever one end when suspension hook rises; Will power cutoff, suspension hook can not surpass the cantilever top again, makes the operating personnel can not receive unexpected injury.
The present invention solves the scheme that its technical matters adopts: the electric power incoming line of loop wheel machine connects contactless switch, button switch and travel switch, and two outlets of contactless switch are connected with electrical motor with two-direction switch.Be installed in cantilever one end to travel switch.Click starter button after the energized, power supply arrives two-direction switch through contactless switch.Work as suspension hook rising column type iron block in the use and promote travel switch, the contactless switch power cutoff, motor quits work.Reach and can not make suspension hook rise the contingency on cantilever top.
The invention has the beneficial effects as follows that the loop wheel machine that travel switch is housed suspension hook can not occur and rise the unexpected dangerous of cantilever top, and is very simple and convenient to former loop wheel machine repacking yet, as long as drop into about 40 yuan fee of material.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1, Fig. 2 are the constructional drawings of travel switch and loop wheel machine.
Fig. 3 is schematic circuit diagram of the present invention.
1. travel switches, 2. cantilevers, 3. column type iron blocks, 4. two-direction switchs, 5. electrical motors, 6. button switchs among the figure.
In Fig. 1, Fig. 2; Iron plate of end welding of cantilever (2); Be fixed on travel switch (1) on the iron plate of cantilever (2), steel wire penetrating column type iron block (3), the column type iron block (3) of rising can strike the travel switch (1) that has lance.
In Fig. 3, be connected a contactless switch, an automatically reset normally open push button switch (6), a NORM CLSD travel switch (1) with two-direction switch (4) front at single phase motor (5).Power connection clicks NORM OPN button switch (6) to contactless switch during operation, and contactless switch starts to work, power supply through contactless switch to two-direction switch (4), the rotating at two-direction switch (4) control motor (5) and stopping.When travel switch (1) that unexpected suspension hook rising column type iron block (3) bump has lance occurring to certain angle, NORM CLSD travel switch (1) breaks off no power, the contactless switch power cutoff that quits work, and electrical motor (5) stops operating.Shift two-direction switch (4) onto earlier and stop electrical motor (5) state; Again with the Pulley of hand or pin rotating motor (5); Can not go to draw belt to rotate with hand; Prevent that hand from being weighed wounded by belt, column type iron block (3) is dropped to below the lance of travel switch (1), travel switch (1) automatically resets.
Claims (1)
1. small-sized safe loop wheel machine that travel switch is housed; Small-sized loop wheel machine is by electrical motor, worm reducer, serving cylinder, steel rope; Suspension hook, support main root are provided with a mobilizable cantilever, the up-down of two-direction switch control suspension hook; It is characterized in that: be connected a contactless switch, the automatically reset button of often opening, a NORM CLSD travel switch with the two-direction switch front at single phase motor; The iron block of steel wire penetrating column type, travel switch are fixed on the iron plate of cantilever, and the iron block of rising can strike the travel switch that has lance.
