Description

Normal closing apparatus for derrick protection door
Technical field
The utility model relates to a kind of normal closing apparatus for derrick protection door.
Background technology
The derrick material elevator of one of vertical transport equipment in the building operation is torn open conveniently because its construction is taken, and advantages such as comformability is strong, efficient is high, good economy performance have obtained the widespread usage of enterprise in charge of construction.But because it is the vehicle for construction of rough type, raising part to be strengthened is not being arranged aspect safety precaution, the function guarantee in addition, floor discharging platform mouth particularly, be is the terminal of discharging platform access way herein, as do not have actv. and block protection, very easily cause the personal height falling accident, in the past the manual control switch's of She Zhiing protective door, because operation inconvenience is performed practically no function basically.
Regulation in " construction safety check criteria " JGJ59-99 " floor is driven the material platform will protective door and effective, and will form settingization, tool ".
In " portal frame and derrick material elevator technical specification of security " JGJ88-92, also emphasize to have the floor mouth to stop door---" outside the porthole at each floor, normally closed stop door should be set, should adopt inter locking gear ".
The protective door that uses in the construction generally all is installed on the derrick at present, and the both sides of protective door are provided with guide rail, and are provided with balance block, protective door is risen more evenly or descend, but the unlatching of protective door is manual operation, and after the cage of lifting in the derrick leaves, protective door also will be by manually closing, therefore, in practical operation, protective door usually is that the someone opens and unmanned closing, this situation is not only violated the building safety standard, and causes safety misadventure easily.
Summary of the invention
The purpose of this utility model is: a kind of normal closing apparatus for derrick protection door is provided, it is to have at protective door that the people opens, unmanned situation of closing, and the normal closing apparatus that designs and produces is after making discharging finish cage to leave, protective door is the energy SELF CL just, thereby makes protective door really play the actv. protective action.
The technical solution of the utility model is: a kind of normal closing apparatus for derrick protection door, this device comprises housing, be provided with slide plate in the housing, slide plate is provided with and is horizontally arranged with chute, establish the bearing pin of pin joint on housing in the chute, the back edge of slide plate is provided with the baffle plate of vertical setting, the front end of slide plate is fixed with dead bolt, between slide plate and the housing spring is installed, spring stretches out outside housing dead bolt all the time forward, also be connected with T shape frame on the bearing pin, the montant of T shape frame is positioned at before the baffle plate, and the cross bar of T shape frame reaches outside the housing backward.
The further technical scheme of the utility model is: a kind of normal closing apparatus for derrick protection door, this device comprises housing, be provided with slide plate in the housing, slide plate is provided with and is horizontally arranged with chute, establish the bearing pin of pin joint on housing in the chute, the back edge of slide plate is provided with the baffle plate of vertical setting, the front end of slide plate is fixed with dead bolt, between slide plate and the housing spring is installed, spring stretches out outside housing dead bolt all the time forward, also be connected with T shape frame on the bearing pin, the montant of T shape frame is positioned at before the baffle plate, and the cross bar of T shape frame reaches outside the housing backward; Described dead bolt comprises the push rod of the front end pin joint of middle part and slide plate, the lower end of push rod and housing pin joint, and the upper end of push rod is fixed with the hyoplastron that stretches out forward.
The utility model has the advantages that:
1. the utility model avoids adopting control methods such as the control of electric signal and travel switch, remote control electromagnetic switch on design structure, and the application of pure physical construction is simple and reliable.On the material selection of member, can adopt different materials to form a pair of friction components at the lubricated relatively poor situation of construction environment, to increase durability and to reduce frictional resistance, usage operation is sensitive reliable.
2. the utility model is simple in structure, low cost of manufacture, stable and reliable for performance, Installation and Debugging and maintaining are convenient, not harsh to derrick parent frame dimensional characteristic, the floor that can solve single cage of derrick material elevator, two cage, standard form derrick and heavy type (overhead) derrick and attached wall construction elevator is effectively driven the normally closed function of material Terrace prevention door.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing and example:
Structural representation of the present utility model when Fig. 1 is the protective door opening;
The utility model was closed the structural representation of protective door when Fig. 2 descended for cage;
The utility model was closed the structural representation of protective door when Fig. 3 rose for cage.
Wherein: 1 housing; 2 slide plates; 3 chutes; 4 bearing pins; 5 baffle plates; 6 dead bolts; 7 springs; 8T shape frame; 9 montants; 10 cross bars; 11 push rods; 12 hyoplastrons, 13 cages; 14 protective doors.
The specific embodiment
Embodiment: as Fig. 1, a kind of normal closing apparatus for derrick protection door, this device comprises housing 1, be provided with slide plate 2 in the housing 1, slide plate 2 is provided with and is horizontally arranged with chute 3, establish the bearing pin 4 of pin joint on housing 1 in the chute 3, the back edge of slide plate 2 is provided with the baffle plate 5 of vertical setting, the front end of slide plate 2 is fixed with dead bolt 6, dead bolt 6 comprises the push rod 11 of the front end pin joint of middle part and slide plate 2, the lower end of push rod 11 and housing 1 pin joint, the upper end of push rod 11 is fixed with the hyoplastron 12 that stretches out forward, between slide plate 2 and the housing 1 spring 7 is installed, spring 7 stretches out outside housing 1 hyoplastron 12 all the time forward, also is connected with T shape frame 8 on the bearing pin 4, the montant 9 of T shape frame 8 is positioned at before the baffle plate 5, and the cross bar 10 of T shape frame reaches outside the housing 1 backward.
During use, the utility model is installed in derrick by protective door top, a derrick outside of building, cross bar 10 stretches into cage 13 hoist trunk positions, when cage 13 rests in a certain flooring, the workmen opens protective door and carries out discharge operation, the upper edge of protective door hangs on the hyoplastron 12 of normal closing apparatus, and cross bar 10 is the level of state, after driving the material end, cage 13 leaves, cage 13 and cross bar 10 moving contacts are stirred the cross bar 10 that stretches out backward from the housing 1 of normal closing apparatus, the aft terminal of cross bar 10 is risen or the segment distance that descends, at this moment, cross bar 10 drives whole T shape frame 8 and rotates around bearing pin 4, and when T shape frame 8 rotated, the upper extreme point of montant 9 or lower extreme point will promote baffle plate 5 backward, slide plate 2 is moved backward, slide plate 2 drives hyoplastrons 12 to after contraction, thereby discharges the protective door that is unlocked, and protective door 14 just can automatic lowering and close.When protective door 14 needed to open, protective door 14 was elevated to the automatic locking in desired location along guide rail and gets final product.
