Abstract
The invention relates to an anti-impact stroke switch. The anti-impact stroke switch comprises a bent steel plate, a stroke switch, a buffering spring, a connecting plate, a height adjusting bolt, a steel sleeve and a safety lock; the buffering spring is connected below the stroke switch and the bent steel plate and can realize a buffering effect for impact borne by the stroke switch; and a fixed end of the buffering spring is provided with the height adjusting bolt through which the height of the spring can be adjusted so that the height of the stroke switch can be controlled. According to the anti-impact stroke switch of the invention, the stroke switch is connected through the buffering spring, and the buffering spring will bend with the stroke switch no matter from which direction the stroke switch bears impact; and after being rest, the buffering spring can automatically rebound to an original position, so that normal work of upper limit control can be ensured.
Description
Technical field
The invention belongs to building machinery technical field, relate to a kind of aerial lift device, specifically a kind of Anti-knocking travel switch.
Background technology
Hanging basket is generally made up of hitch, track, Rail climbing device, basket body and safety system.Basket body can be mobile with vertical along track cross level walking, and staff can arrive each facade of building, is mainly used in steamer, building or structures exterior window and the operation such as outside Wall Cleaning, maintenance.Along with the raising that urban construction requires, require to carry out the operations such as regular cleaning and maintenance to glass of building window, exterior wall etc.In recent years, along with increasing of high-rise or high-rise building alien invasion inspection and maintenance operation, hanging basket relies on the advantages such as its structure is simple, easy to use, make market to its demand increasing.Hanging basket needs travel switch to control basket body extreme position in motion process, because upper stroke switch is arranged on safety lock, and rock during hanging basket operation, when standard travel switch connecting plate all around any direction all may be hit curved at once or broken after encountering barrier, upper limit is caused to control malfunctioning, thus, the Anti-knocking travel switch developing a kind of convenient, reliability flexibly high has important engineering significance.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, provides a kind of Anti-knocking travel switch.
According to technical scheme provided by the invention: this Anti-knocking travel switch described comprises bending steel plate, travel switch, buffer spring, connecting plate, height adjustment bolt, steel bushing and safety lock; Described travel switch is arranged on bending steel plate, upper control limit position.
As a further improvement on the present invention, below described travel switch and bending steel plate, be connected with buffer spring, have a cushioning effect to the impact that travel switch is subject to.
As a further improvement on the present invention, described buffer spring stiff end is equipped with height adjustment bolt, can the height of regulating spring, thus controls the height of travel switch.
The present invention compared with prior art, advantage is: structure is rationally ingenious, and crashproof travel switch connects with spring, and no matter all around which direction can and then bend after being clashed into, home position can be got back to by appliance for releasing single again, to ensure the normal work that upper limit controls after reset.
Accompanying drawing explanation
Fig. 1 is the integrally-built schematic diagram of the present invention,
Fig. 2 is that schematic diagram is looked on a left side for structure of the present invention.
Description of reference numerals: 1-bending steel plate, 2-travel switch, 3-buffer spring, 4-connecting plate, 5-height adjustment bolt, 6-steel bushing, 7-safety lock.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: the present invention forms primarily of bending steel plate (1), travel switch (2), buffer spring (3), connecting plate (4), height adjustment bolt (5), steel bushing (6) and safety lock (7); Described travel switch (2) is arranged on bending steel plate (1), upper control limit position, travel switch (2) and bending steel plate (1) are connected with buffer spring (3) below, a cushioning effect is had to the impact that travel switch (2) is subject to, buffer spring (3) is through steel bushing (6), be fixed on connecting plate (4) by height adjustment bolt (5), connecting plate (4) is fixed by welding in again on safety lock (7).
During embody rule, as shown in Figure 1 to Figure 2, described safety lock (7) moves up and down along with hanging basket basket body, when arriving upper limit (UL), travel switch (2) is subject to colliding automatic cut-off power, buffer spring (3) is out of shape by compression, travel switch (2) is played to the effect of shock absorbing, ensures the normal work that upper limit controls.
Claims (4)
1. an Anti-knocking travel switch, is characterized in that: this Anti-knocking travel switch comprises bending steel plate (1), travel switch (2), buffer spring (3), connecting plate (4), height adjustment bolt (5), steel bushing (6) and safety lock (7); Described travel switch is arranged on bending steel plate, upper control limit position.
2. Anti-knocking travel switch as claimed in claim 1, is characterized in that: described travel switch (1) and bending steel plate (1) are connected with buffer spring (3) below, have a cushioning effect to the impact that travel switch (2) is subject to.
3. Anti-knocking travel switch as claimed in claim 1, is characterized in that: described buffer spring (3) stiff end is equipped with height adjustment bolt (5), can the height of regulating spring, thus controls the height of travel switch.
4. Anti-knocking travel switch as claimed in claim 1, it is characterized in that: described travel switch (2) connects with buffer spring (3), no matter all around which direction can and then bend after being clashed into, home position can be got back to by appliance for releasing single again, to ensure the normal work that upper limit controls after reset.
