Abstract
The utility model discloses a construction elevator protective door self-locked device which comprises a door frame and a protective door. A linkage lock body is installed on the top of the door frame. A circular arc transition plate is arranged at the front portion of the linkage lock body. A clamping groove is formed in the middle of the linkage lock body. A bolt is arranged on the back portion of the linkage lock body. The linkage lock body is hinged to the door frame through the bolt. A baffle ring is installed on the linkage lock body. A pulling rope is fixedly arranged on the linkage lock body. The construction elevator protective door self-locked device has the advantages of being simple in structure, easy to manufacture, high in practicability, safe, reliable, simple in structure and practical and convenient to install due to the fact that a top linkage lock is adopted on the construction elevator protective door, eliminating the potential safety hazards due to the fact that the construction elevator protective door is not closed, and being low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of high-building construction protective door safety device, in particular, relates to a kind of protection door for construction elevator self-locking device.
Background technology
The high-building construction elevator is the requisite vertical transferring apparatus of building operation, and its floor safety protective door does not belong to the accessory of construction elevator, processes voluntarily installation by unit in charge of construction in actual use.Existing protection door for construction elevator adopts latch to close the door basically, although comparison is simple, uses this traditional protection door for construction elevator, the potential safety hazards such as the protective door latch is not plugged, protective door is not closed, latch damage the most easily occur.
The utility model content
The utility model is for the deficiency of existing product, and a kind of protection door for construction elevator self-locking device simple in structure, practical, safe and reliable, easy for installation is provided.
Protection door for construction elevator self-locking device of the present utility model, comprise doorframe, protective door, described doorframe top is equipped with the blocking lock body, described blocking lock body previous section is provided with one section arc transition plate, centre portion is provided with draw-in groove, aft section is provided with bolt and stay cord, and described blocking lock body is hinged by bolt and doorframe, is installed by welding with baffle ring above described doorframe.The arc transition plate of described blocking lock body laterally is fixed with round bar.Described doorframe inboard also is equipped with the protective door baffle plate.
The beneficial effects of the utility model are: (1) is simple in structure, is easy to make; (2) practical, safe and reliable, protection door for construction elevator adopts the top blocking lock, and installation simple in structure is practical and convenient, eliminates the construction elevator safety door and does not shut the potential safety hazard that causes; (3) low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of protection door for construction elevator self-locking device of the present utility model;
Fig. 2 is the structural representation of the blocking lock body of protection door for construction elevator self-locking device of the present utility model;
In figure: blocking lock body 1, bolt 2, round bar 3, stay cord 4, baffle ring 5, protective door baffle plate 6, doorframe 7, protective door 8.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, protection door for construction elevator self-locking device of the present utility model mainly is comprised of blocking lock body 1, bolt 2, round bar 3, stay cord 4, baffle ring 5, protective door baffle plate 6, doorframe 7, protective door 8.
Described doorframe 7 tops are equipped with blocking lock body 1, described blocking lock body 1 previous section is provided with one section arc transition plate, and centre portion is provided with draw-in groove, and aft section is provided with bolt 2 and stay cord 4, described blocking lock body 1 is hinged by bolt 2 and doorframe 7, and described doorframe 7 tops are installed by welding with baffle ring 5.The arc transition plate of described blocking lock body 1 laterally is fixed with round bar 3.Described doorframe 7 inboards also are equipped with protective door baffle plate 6.
As shown in Figure 1 and Figure 2: when using the utility model, blocking lock body 1 is arranged on above doorframe 7, blocking lock body 1 forms turning joint by the annulus of welding on bolt 2 and doorframe 7, and above doorframe 7 and blocking lock body 1 baffle ring 5 of the anti-tipping of welding, prevent when opening the door that stay cord 4 is firmly excessive, with blocking lock body 1 drag turn over ineffective.Doorframe 7 installed inside have protective door baffle plate 6, protective door baffle plate 6 withstands blocking lock body 1, make blocking lock body 1 maintenance level, because the previous section of blocking lock body 1 is circular-arc, when closing protective door, owing to jumping in the stressed extruding meeting of blocking lock lock body 1, and the round bar 3 and the protective door 8 that fall behind blocking lock because deadweight is lower form self-lockings, and door-closing operation is simple.When opening the door, only need the stay cord 4 after blocking lock is pulled gently, push protective door 8 open and can open the door.
Protection door for construction elevator self-locking device of the present utility model is simple in structure, is easy to make; Practical, safe and reliable, protection door for construction elevator adopts the top blocking lock, and is simple in structure, installs practical and conveniently, can eliminate the construction elevator safety door and not shut the potential safety hazard that causes; Low cost of manufacture.
