Description
Technical field
The utility model is related to civil air defense constructions and installations equipment processing and manufacturing technologies, and in particular to a kind of people's air defense door leaf back-pressure is strong
Equipment.
Background technology
It is typically all to use channel steel that civil air defense constructions and installations, which protects big steel casement door, I-steel and steel plate group weldering, due to door leaf size compared with
Greatly, weight is big, due to the influence of thermal stress after welding, it is easy to and cause door leaf modification, surface planarity that standard requirement is not achieved,
Influence sealing effect.The correction of existing door leaf generally slings door leaf, is corrected to it after being fixed with fixed frame, often corrects
After one position will sling shift position with day handlebar door leaf, then next position is corrected, this requires that must be equipped with one
A overhead traveling crane services for it, frequently lifting movement, and working efficiency is low, and overhead traveling crane uses frequent.Door leaf after correction will also drill
Operation, needs manually to drill after door leaf is put down, and due to needing drilling hole amount very much, holds drill bit boring work amount very
Greatly, and door leaf can not be processed since own vol is excessive on drilling machine.
Utility model content
The purpose of this utility model is that aiming at the deficiencies in the prior art, a kind of raising production efficiency, slow is provided
It solves overhead traveling crane pressure, the combined people's air defense door leaf back-pressure of device of correction drilling two procedures is corrected into drilling equipment.
For this purpose, the utility model uses following technical scheme：
A kind of people's air defense door leaf back-pressure correction drilling equipment, including platform, portal frame, jack and power drill；Described gantry
The jack and the power drill are connected on frame；The portal frame is dynamic along platform sideslip；The jack and the power drill
It is slided along the portal frame；
The top of the platform extends outward extension；The portal frame bottom end is equipped with pulley and hook portion；The cunning
Wheel is positioned at the top of the extension；The hook portion is located at the lower section of the extension, the hook portion and the extension
Between there are spaces.
Further description, the front end of the jack are equipped with the cushion block of truncated cone-shaped；The smaller bottom surface of the cushion block with
The jack is connected.
The rocking handle of further description, the jack is driven by motor.
Further description is provided with the pulley protector that steel plate connects into outside the pulley；The pulley is protected
Protection unit is fixed on the both sides of the pulley and covers on the first half of the pulley, and is connected with the portal frame.
Further description, the extension are equipped with smooth pulley groove, and the pulley moves in the pulley groove
It is dynamic.
The beneficial effects of the utility model：It completes that the pressure of door leaf is corrected and drilled in the case where not moving door leaf
Process saves manpower, improves production efficiency.The mode of original positive pressure correction is changed, the correction mode of back-pressure is more readily detected
Situation is corrected, correction quality is improved.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the overall structure diagram of one embodiment of the utility model.
Wherein：Door leaf 01, platform 1, extension 11, portal frame 2, pulley 21, pulley protector 211, hook portion 22, thousand
Jin top 3, cushion block 31, motor 32 and power drill 4.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, a kind of people's air defense door leaf back-pressure corrects drilling equipment, including platform 1, portal frame 2, jack 3 and dynamic
Power bores 4；The jack 3 and the power drill 4 are connected on the portal frame 2；The portal frame 2 is dynamic along platform sideslip；It is described
Jack 3 and the power drill 4 are slided along the portal frame 2；
The top of the platform 1 extends outward extension 11；2 bottom end of the portal frame is equipped with pulley 21 and hook portion
22；The pulley 21 is located at the top of the extension 11；The hook portion 22 is located at the lower section of the extension 11, the hook
There are spaces between extension portion 22 and the extension 11.
When being corrected to door leaf, power drill 4 is moved to the side of portal frame 2, according to need to correct on door leaf
Position adjusts portal frame 2 and jack 3, and jack 3 is made to be located at the surface waited at correction, drives jack 3, will wait at correction
It flattens.Pulley 21 contributes to the movement of portal frame 2, hook portion 22 to hook extension 11 from bottom surface, prevents from working in jack 3
When, the reaction force of jack 3 jacks up portal frame 2.Since hook portion 22 is not in close contact with extension 11, hook portion
22 do not interfere with the normal movement of portal frame 2.After door leaf is corrected, jack 3 is moved to the side of portal frame 2, is adjusted
Power drill 4 is moved to position hole to be drilled by the position of portal frame 2 and power drill 4, is driven power drill 4, is bored to door leaf
Hole.One portal frame 2 carries 4 two devices of jack 3 and power drill, can be completed to door leaf in the case where not moving door leaf
Correction and drilling operating, save manpower, improve production efficiency.
Further description, the front end of the jack 3 are equipped with the cushion block 31 of truncated cone-shaped；The smaller bottom of the cushion block 31
Face is connected with the jack 3.
Because the hydraulic axis face area of jack 3 is smaller, the effect for correcting door leaf is bad, and cushion block 31 can increase very heavy
The force area on top 3, improves the rectification effect of door leaf.
The rocking handle of further description, the jack 3 is driven by motor 32.
When correcting door leaf, the position of portal frame 2 and jack 3 is adjusted, jack 3 is made to be located at the surface waited at correction,
Motor 32 is started, the i.e. extrudable door leaf of jack 3 corrects it.Whole process only needs one man operation, and operating personnel
Jack 3 need not be directly operated, correction situation can be paid close attention to constantly, so the effect of correction can also be improved.
Further description is provided with the pulley protector 211 that steel plate connects into outside the pulley 21；The cunning
Wheel protective device 211 be fixed on the both sides of the pulley 21 and cover on the first half of the pulley 21, and with 2 phase of the portal frame
Even.
Because pulley 21 will carry portal frame 2, very strong bearing capacity is needed.Pulley protector 211 can have
Effect shares the power that pulley is carried, and reduces the load of pulley 21, extends the service life of pulley 21.
Further description, the extension 11 are equipped with smooth pulley groove, and the pulley 21 is in the pulley groove
Interior movement.
Smooth pulley groove can reduce the frictional resistance of pulley 21, reduce the loss of pulley 21, extend making for pulley 21
Use the service life.Pulley groove can also limit pulley 21, it is ensured that it is only moved along pulley groove.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
