Description
Technical field:
The present invention relates to a kind of secondary opening door hook, is a vitals of the secondary opening door for boiler coal filling hole, belongs to boiler manfacturing equipment technical field.
Background technology:
At present, the known door capable of being opened for boiler coal filling hole is a door capable of being opened, when needing coal, first opens the door capable of being opened of boiler coal filling hole, then add coal in the coal store of boiler.Due to boiler operationally, the inside and outside pressure differential existed of boiler is comparatively large, and the danger directly opening the door capable of being opened of boiler coal filling hole is very large, can damage time serious to unlatching personnel.In order to prevent having an accident during the door capable of being opened directly opening boiler coal filling hole, boiler industry is in the urgent need to a kind of door capable of being opened with the boiler coal filling hole of secondary opening function.This topmost parts of door capable of being opened with the boiler coal filling hole of secondary opening function are exactly secondary opening door hook, only have design secondary opening door hook, and are arranged on secondary opening door, secondary opening door just can be made to have the function of secondary opening.
Summary of the invention:
The object of the invention is to provide a kind of secondary opening door hook that secondary opening door can be made to have secondary opening function.
For achieving the above object, the technical solution used in the present invention is:
One secondary opening door hook, comprise spherical sleeve and coupler body composition, the top of coupler body is handle, and bottom is hook, and the position be connected with hook at handle is provided with an axis hole.A plastic spherical sleeve is installed on the top of handle, both laborsaving during switch secondary opening door, right heat insulation, convenient operation.Described hook has two gib heads, namely goes up gib head and lower gib head, and the position of upper gib head, higher than lower gib head, is provided with one section of open hole between upper gib head and lower gib head.
In the present invention, described upper gib head is designed to " u " shape, lug boss is provided with at leading inside, prevent fixed axis from skidding off in upper gib head, bottom upper gib head, be provided with Baltimore groove, the elasticity of upper gib head can be strengthened, clamping section is provided with in the both sides of Baltimore groove, the external peripheral surface of gib head and fixed axis can be made to form two linear contact lay, add the contact site of gib head and fixed axis, in order to the axle that is fixedly clamped.
In the present invention, the inside and outside surface of described lower gib head is all set to circular arc, and end is provided with level and smooth extension, has both been convenient to hook fixed axis, and when being convenient to again open the door, fixed axis is deviate from from lower gib head.
In the present invention, the length of described open hole is greater than the diameter of fixed axis, when opening the door, open hole being faced fixed axis, being convenient to coupler body and being separated with fixed axis.
The invention has the beneficial effects as follows, construct simple and easy, easy to manufacture, easy to use, safety is high, and long service life is convenient to I&M, and secondary opening door can be made to have secondary opening function.
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is closed condition figure of the present invention.
Fig. 3 is first time opening figure of the present invention.
In figure: gib head, 311 clamping sections, 312 lug bosses, 313 Baltimore grooves, 32 times gib heads, 321 extension, 4 axis holes, 5 open holes, 6 fixed axis on 1 spherical sleeve, 2 handles, 3 hooks, 31.
Detailed description of the invention:
As shown in Figure 1, a kind of secondary opening door hook, comprise spherical sleeve 1 and coupler body composition, the top of coupler body is handle 2, and bottom is hook 3, and the position be connected with hook 3 at handle 2 is provided with an axis hole 4.A plastic spherical sleeve 1 is installed on the top of handle 2, both laborsaving during switch secondary opening door, right heat insulation, convenient operation.Described hook 3 has two gib heads, namely goes up gib head 31 and lower gib head 32, and the position of upper gib head 31, higher than lower gib head 32, is provided with one section of open hole 5 between upper gib head 31 and lower gib head 32.Described upper gib head 31 is designed to " u " shape, lug boss 312 is provided with at leading inside, prevent fixed axis 6 from skidding off in upper gib head 31, Baltimore groove 313 is provided with bottom upper gib head 31, the elasticity of upper gib head 31 can be strengthened, be provided with clamping section 311 in the both sides of Baltimore groove 313, gib head 31 can be made to form two linear contact lay with the external peripheral surface of fixed axis 6, add the contact site of gib head 31 and fixed axis 6, in order to the axle 6 that is fixedly clamped.The inside and outside surface of described lower gib head 32 is all set to circular arc, and end is provided with level and smooth extension 321, has both been convenient to hook fixed axis 6, and when being convenient to again open the door, fixed axis 6 is deviate from from lower gib head 32.The length of described open hole 5 is greater than the diameter of fixed axis 6, when opening the door, open hole 5 being faced fixed axis 6, being convenient to coupler body and being separated with fixed axis 6.
As shown in Figure 2, the upper gib head 31 of secondary opening door hook 3 hooks fixed axis 6, and now secondary opening door is locked.
As shown in Figure 3, the lower gib head 32 of secondary opening door hook 3 hooks fixed axis 6, and now secondary opening door opens a bit of distance.
Operating principle and method of operating: when secondary opening door by locked time, as shown in Figure 2, driving handle 2 to the right, fixed axis 6 is deviate from from upper gib head 31, coupler body moves upward along with secondary opening door, in the process moved upward, lower gib head 32 hooks fixed axis 6, and secondary opening door stops moving upward, and now secondary opening door opens a bit of distance.Then driving handle 2 left, when the open hole 5 of hook 3 faces fixed axis 6, upwards starts secondary opening door, and hook 3 is separated with fixed axis 6, and secondary opening door is opened.
When secondary opening door need by locked time, first tightly pressed by secondary opening door, make gib head 31 face fixed axis 6, at this moment firmly driving handle 2 left, upper gib head 31 opens suitable for reading under elastic reaction, hooks fixed axis 6.Now, fixed axis 6 is clamped in two clamping sections 311 of upper gib head 31, and the lug boss 312 of upper gib head 31 front end stops fixed axis 6, can prevent fixed axis 6 from skidding off in upper gib head 31.
