Description
Technical field:
The utility model relates to a kind of elevator well head protective door that uses in constructure construction procedure.
Background technology:
Building trade has the danger of height in work progress.In order to ensure construction worker's life security, the generation of prevention casualty accident according to the safety standard of building operations, must be installed protective door to the elevator well head in building construction process.The door body of existing elevator well head protective door generally adopts lattice door, during installation, needs to adopt electric welding machine that it is welded on the concrete wall on elevator shaft doorway.Finish when removing in construction, use the cutting of gas welding cutting torch to remove.Adopt this protective door to have following shortcoming: one, need to adopt the electric welding machine welding respectively and adopt the cutting of gas welding cutting torch in installation and demolishing process, labour intensity is big, inefficiency; Two, do not have interchangeability, can not repeat turnover and use; Three, the protective door after the dismounting becomes scrap iron and steel, causes bigger waste, has increased the cost of construction.In addition, this protective door adopts resupinate mode to open, with a unfixed they sup-port, when the constructor when the elevator well head is constructed, sometimes knock support bar accidentally over, lattice door will fall to be squeezed into the constructor in the elevator shaft, and accident causes casualties.
Summary of the invention:
The technical problems to be solved in the utility model is, existing elevator well head protective door install and remove labour intensity big, can not repeat that turnover is used, the waste steel.For solving this technical problem, the utility model by the following technical solutions: elevator well head protective door comprises a body 1 and hinge 2.Its special character is: also comprise hinge seat 3, have installing hole 4 on the hinge seat 3.Hinge 2 is fixed on the hinge seat 3, and the top of door body 1 is installed on the hinge 2.
Door body 1 of the present utility model has bracing or strutting arrangement 13.
Under door body 1 state that upwards upset is opened, bracing or strutting arrangement 13 is used for supporting door body 1, and a body 1 is remained on a certain angle of opening, and prevents a body 1 upset downwards under the effect of deadweight.
Bracing or strutting arrangement 13 of the present utility model comprises fixed axis 14, axle sleeve 15, gripper shoe 16 and supporting seat 17.Fixed axis 14 is fixed on the side 19 of a body 1, and the axis of fixed axis 14 is parallel with the axis of first axle sleeve 5.Axle sleeve 15 is enclosed within on the fixed axis 14, and it and gripper shoe 16 are fixed together.Has the tooth 18 that can contact on the supporting seat 17 with the bottom of gripper shoe 16.
Gripper shoe 16 can be rotated around fixed axis 14 by axle sleeve 15, thereby regulates the angle of gripper shoe 16, and the bottom of gripper shoe 16 is contacted with tooth 18 on the supporting seat 17.Supporting seat 17 is fixed on the wall, and it can be integral with hinge seat 3.Tooth 18 on the supporting seat 17 is used to block gripper shoe 16, and gripper shoe 16 is played a supporting role by axle sleeve 15 and fixed axis 14 opposite house bodies 1.For door body 1 is supported on different angles, many teeth that are parallel to each other 18 can be arranged on the supporting seat 17.
Backing pin 20 can adopt bolt, also can adopt other can block the device of axle sleeve 15.
Compare with existing elevator well head protective door, the utility model is owing to have hinge seat 3, and has installing hole 4 on the hinge seat 3, and the utility model can be mounted and dismounted on concrete wall easily, and is simple to operate.Because the utility model can not cause damage to each component in the installation and removal process, make the utility model can repeat turnover and use, saved steel, reduced the construction cost of unit in charge of construction.In addition, because the two ends of hinge axis 7 of the present utility model have first external screw thread 9 and second external screw thread 10 respectively, and first external screw thread 9 and second external screw thread 10 have first nut 11 and second nut 12 that is mated respectively, fixed axis 14 has backing pin 20, makes the utility model installation and removal convenient.Owing to the utlity model has bracing or strutting arrangement 13, door body 1 can be locked on a certain angle of opening, when the constructor constructs at the elevator well head, can prevent that a body 1 upset downwards under the effect of deadweight from injuring the constructor by a crashing object, avoids the generation of accident.

The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figures 1 to 4, present embodiment is a kind of elevator well head protective door that uses in building construction process, and it comprises a body 1, hinge 2, hinge seat 3 and bracing or strutting arrangement 13.About hinge 2, hinge seat 3 and bracing or strutting arrangement 13 respectively have two.Door body 1 has top 8, bottom 21, left and right sides side 19 and fence bar 22, and top 8, bottom 21 and left and right sides side 19 are welded into rectangular frame, and some fence bars 22 are between two left and right sides sides 19.Each fence bar 22 is parallel to each other, and equidistantly distributes, and their two ends are welded on respectively on top 8 and following 21.Hinge 2 is made up of first axle sleeve 5, second axle sleeve 6, axle 7, first nut 11 and second nut 12.Two first axle sleeves 5 are weldingly fixed on respectively on the two ends of top 8 of a body 1, and two second axle sleeves 6 are weldingly fixed on respectively on two hinge seats 3, and axle 7 is enclosed within first axle sleeve 5 and second axle sleeve 6.The two ends of axle 7 have first external screw thread 9 and second external screw thread, 10, the first external screw threads 9 and second external screw thread 10 respectively and cooperate with first nut 11 and second nut 12 respectively.Bracing or strutting arrangement 13 is made up of fixed axis 14, axle sleeve 15, gripper shoe 16, supporting seat 17 and backing pin 20.Article two, fixed axis 14 is weldingly fixed on respectively on the left and right sides side 19 of a body 1, and the axis of fixed axis 14 is parallel with the axis of first axle sleeve 5.The external surface of axle sleeve 15 is weldingly fixed on the top of gripper shoe 16, and axle sleeve 15 is enclosed within on the fixed axis 14.Gripper shoe 16 is a rectangular flat plate, adopts the steel plate manufacturing.Backing pin 20 adopts bolt, and the outer end of fixed axis 14 has screw, and backing pin 20 spiral shells are in this screw.Backing pin 20 blocks axle sleeve 15, prevents the axial disengaging fixed axis 14 of axle sleeve 15 along fixed axis 14.Hinge seat 3 is integral with supporting seat 17, and they are tabular, adopts the steel plate manufacturing.Have four installing holes 4 on the hinge seat 3.Have three parallel teeth 18 on the supporting seat 17, tooth 18 can contact with the bottom of gripper shoe 16
