Abstract
A device for protecting the cable of a construction hoist comprises a cable clamping plate, a lever, a travel switch, an underframe and a spring; the cable clamping plate is arranged at one end of the lever; the middle of the lever is connected to the underframe through a hinge; the other end of the lever is connected to the underframe through the spring; the vertical plate is arranged at one end of the underframe; the travel switch is arranged on the vertical plate; a pressure plate is arranged above the travel switch; one end of the pressure plate is hinged on the vertical plate; a second spring is arranged between the pressure plate and the vertical plate; and the length of the pressure plate is greater than the distance between the hinge point of the pressure plate and a contact terminal of the travel switch. The device for protecting the cable of the construction hoist is characterized in that tension on one side of the cable is detected through the lever; the pressure plate is arranged at the other end of the lever and can touch the travel switch under the action of the second spring; therefore, when a traveling cable is caught by an object so as to cause the tension of the cable to change abnormally, the abnormality is fed back to the travel switch through the lever, and the power supply is cut off, thereby preventing the cable from being damaged. The device has the advantages of simple and reasonable structural design and good safety performance and can protect cables effectively.
Description
Technical field:
The utility model relates to mechanical field, and particularly building hoist specifically is a kind of building hoist cable protecting device.
Background technology:
Building hoist is a kind of with cage manned, loading, makes the construction machinery and equipment of perpendicular movement along guide rail bracket, and it is mainly used in the construction and the maintenance of skyscraper.In the process of cage operation, its cable moves up and down with cage.In the prior art, in the whole stroke of cage, the cable guide frame all is housed, to guarantee the running orbit of cable every certain height.But because of building operation environment more complicated, often run into the situation of blowing hard, trailing cable skids off from the rubber baffle of guide frame probably, hang on the objects such as building or scaffolding steel pipe, also may catch on the cable guide frame, and the position of cage operation this moment is higher, the driver is difficult to unusual circumstance, situation such as cause that cable is broken, physical damage, guide rail bracket are charged causes safety misadventure.
The utility model content:
The purpose of this utility model is to provide a kind of building hoist cable protecting device; the trailing cable that described this building hoist cable protecting device will solve building hoist in the prior art might be thrown off from guide frame and hung on the object, and does not have the actv. safety method to cause cable to break, cause the technical matters of safety misadventure.
The purpose of this utility model is achieved through the following technical solutions: comprise the cable clamping piece, lever, travel switch, underframe and spring, the cable clamping piece is arranged on an end of lever, be connected through the hinge on underframe in the middle of the lever, the lever other end is connected on the underframe by spring, also be provided with travel switch on the underframe, wherein, be provided with vertical plate at underframe one end, on this vertical plate, be provided with described travel switch, above travel switch, be positioned at vertical plate and be provided with pressing plate, this pressing plate one end is articulated on the vertical plate, be provided with second spring between pressing plate and the vertical plate, second spring applies anticlockwise moment to pressing plate, and the length of pressing plate is greater than the distance between its hinge-point and the travel switch contact.
Travel switch is arranged on the vertical plate in horizontal direction.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model in the building hoist cable protecting device by the pulling force that lever comes check cable one side is set; and be provided with pressing plate at the lever other end; this pressing plate can touch travel switch under second action of the spring; when tangling object, trailing cable feeds back to travel switch by lever when causing the tension variations of cable unusual; cut off the electricity supply, prevent cable bad, the structure design advantages of simple; can protect cable by actv., safety performance is good.
Description of drawings:
Fig. 1 is the structural representation of the utility model building hoist cable protecting device.
The specific embodiment:
As shown in Figure 1; described building hoist cable protecting device; comprise cable clamping piece 1; lever 2; travel switch 4; underframe 8 and spring 5; cable clamping piece 1 is arranged on an end of lever 2; be connected on the underframe 8 by hinge 3 in the middle of the lever 2; lever 2 other ends are connected on the underframe 8 by spring 5; also be provided with travel switch 4 on the underframe 8; wherein; be provided with vertical plate 6 at underframe 8 one ends; be provided with described travel switch 4 on this vertical plate 6, part is embedded in horizontal direction is arranged on the vertical plate 6 for travel switch 4, above travel switch 4; be positioned at vertical plate 6 and be provided with pressing plate 9; these pressing plate 9 one ends are articulated on the vertical plate 6; be provided with second spring, 10, the second springs 10 between pressing plate 9 and the vertical plate 6 and apply anticlockwise moment for pressing plate 9, the length of pressing plate 9 is greater than the distance between its hinge-point and travel switch 4 contacts.
Can rotate by lever 2 when causing the tension variations of cable unusual when trailing cable 7 tangles object, after lever 2 was thrown off with pressing plate 9, pressing plate 9 touched travel switch 4 under the effect of second spring 10, cut off the electricity supply, and prevents cable bad, avoids having an accident.
Certainly, second spring also can be the torsion spring that is arranged on the pressing plate jointed shaft.
