Abstract
The utility model discloses a fence door protection mechanism for a construction elevator. The fence door protection mechanism comprises a platform, a connecting rod mechanism, a fence door and the construction elevator, wherein the upper surface of the platform is provided with a positioning pit corresponding to a closing position of the fence door; a positioning pin is inter-looped on a spring and is inserted into the positioning pit to be in an elastic stretch state; the fence door is clamped by the upper end of the positioning pin to form normal-state limiting, and the lower end of the positioning pin is hinged with the connecting rod mechanism to form a linkage protection structure; the connecting rod mechanism consists of a fixed rod, a driven rod and a lever; a slide block which is hinged with the free end of the driven rod is in sliding fit with a guide rail; and the free end of the lever is provided with a roller which is exposed out of the outer edge of the platform. The positioning rod at the bottom of one face, facing the fence door, of the construction elevator is matched with the roller at the free end of the lever to form control over switching action of the linkage protection structure. If the construction elevator is off-position or is not stopped in place, the fence door cannot be opened. The fence door can only be freely opened when the construction elevator is precisely stopped. The fence door protection mechanism has the advantages of simple and reliable structure and suitability for being matched with the construction elevator in the building industry.
Description
Technical field
The utility model relates to a kind of vehicle for construction safety structure, and specifically, the utility model relates to a kind of construction elevator mouth barrier safety structure.
Background technology
The construction elevator that use the building industry camp site is a kind of vertical Lift type elevator, and it is one of major equipment of modern high-rise building construction.Because construction elevator is temporary up-down machinery, usually be attached to thirty years of age of skin and with preset platform and dock every layer of camp site of communication.Install because construction elevator is exposed, so safety performance is had very high requirement, the commodity construction elevator must satisfy the requirement of safe transport building materials and workmen in the building operation on the market.In the use procedure, after construction elevator arrival target preset platform, the barrier that must open on the platform mouth could be realized current.The barrier of prior art is by artificial unlatching, stops with construction elevator and whether puts that it doesn't matter in place.Because of particularity and the complexity of building operation environment, construction elevator occurs once in a while to be stopped and not in placely to have, if the workmen is careless under this situation, just may habituation to open barrier current.Error is little if construction elevator is stopped, and it is current inconvenient to cause, if error is large, easily causes serious accident, and barrier is opened very important after the construction elevator stop puts in place thus.
The utility model content
The utility model mainly for the switch of existing construction elevator mouth barrier with stop the irrelevant problem that whether puts in place, propose a kind of simple and reasonable for structure, barrier and construction elevator spacing, the safe and reliable construction elevator mouth barrier safety structure that links.
The utility model is achieved through the following technical solutions technical goal.
Construction elevator mouth barrier safety structure, it comprises with the connecting rod mechanism of platform limit mounting and plug-type barrier and construction elevator.Its improvements are: the corresponding barrier off position of described platform upper surface is provided with the location pit.The vertical insertion in the pit of location is in the elastic stretch shape behind the described locating dowel pin string sleeve spring, and the open slot OK a karaoke club barrier that expose the upper end consists of the normality position limiting structure, and the connecting rod mechanism under lower end and the platform is hinged and consists of the interlock safety structure.Described connecting rod mechanism is comprised of fixed pole, follower lever and lever, the slide block that the follower lever free hinge ending connection connects and guide rail bearing fit, and the lever free end is provided with the outer edge that roller exposes platform.The one side bottom that described construction elevator faces barrier is provided with radius stay, and the free-ended roller pairing of radius stay and lever consists of the switch motion of control interlock safety structure.
In the said structure, the spring of configuration is Compress Spring, and the radius stay end that is positioned at the construction elevator bottom is circular-arc or spherical, also can substitute with roller.
The utility model compared with prior art has following good effect:
1, the interlock safety structure is simple, reasonable, easily makes;
2, by the interlock safety structure of construction elevator stop position control fence door switch, stop position is accurate, and is safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation, and construction elevator is stopped control not in place less than lever among the figure, and the barrier pin card position that is positioned is in insurance and closes situation.
Fig. 2 is the utility model structural representation, and construction elevator is stopped and put in place among the figure, lifts on the radius stay control lever, and locating dowel pin inside contracts the back bar door and can open.
Fig. 3 is Fig. 1 left view.
The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Construction elevator mouth barrier safety structure shown in Figure 1, it comprises with the connecting rod mechanism of platform 7 limit mounting and plug-type barrier 8 and construction elevator 9.The utility model is provided with the location pit at corresponding barrier 8 off positions of platform 7 upper surfaces.Be in the elastic stretch shape in the spring 5 rear vertical insertion location pits of described locating dowel pin 6 string cover pressure textures, the open slot screens barrier 8 that expose the upper end consists of the normality position limiting structure, and the connecting rod mechanism under lower end and the platform 7 is hinged and consists of the interlock safety structure.Described connecting rod mechanism is comprised of fixed pole 1, follower lever 2 and lever 4, slide block 2.1 and guide rail 3 bearing fits that follower lever 2 free hinge ending connections connect, and lever 4 free ends are provided with the outer edge that roller 4.1 exposes platform 7.The one side bottom that described construction elevator 9 faces barrier 8 is provided with radius stay 9.1, and radius stay 9.1 consists of the switch motion of controlling the interlock safety structure with lever 4 free-ended roller 4.1 pairings.Radius stay 9.1 ends that are positioned at construction elevator 9 bottoms in the present embodiment are circular-arc.
During the actual use of the utility model, off normal or stop not in placely when construction elevator 9, the interlock safety structure is in the normal state spacingly, and barrier 8 can not be pushed open.In case construction elevator 9 operations are also accurately stopped target and preset platform, the radius stay 9.1 that is positioned at construction elevator 9 bottoms promotes lever 4 free-ended rollers 4.1, and locating dowel pin 6 is sunk, and this moment, barrier 8 can freely be pushed open, realized the purpose of safe passing.
