Abstract
The utility model discloses a kind of safety-type hydraulic automatic well lids, including well lid (1), well lid mounting base (2) and well lid automatic-opening mechanism (3), integrally formed with the installation cavity (2a) towards outer wall protrusion on the inner wall of the well lid mounting base (2), infrared emission light curtain (4) are installed in the installation cavity (2a), after infrared emission light curtain (4) installation, the inner wall of well lid mounting base (2) must not be protruded.By increasing infrared emission light curtain in well lid mounting base inner wall, for detecting whether well head has construction personnel and material disengaging, to improve the safety of construction；Infrared emission light curtain hides installation, is not take up operating space in well, and can effective protection infrared emission light curtain.
Description
Technical field
The utility model belongs to town road infrastructure technique field, and in particular to a kind of highly-safe hydraulic automatic
Opener well lid.
Background technique
With the development of well lid technology, occur some well lids that can be automatically turned on, well lid automatic-opening mechanism on the market
Mainly it is made of hydraulic cylinder, lifting overturning seat.Well lid is hinged on lifting overturning seat, and hydraulic cylinder pushes well by lifting overturning seat
Lid level overturns opening again after rising, it is exactly the opposite that well lid closes the process opened with well lid.
Existing hydraulic automatic well lid realizes that well lid opens and closes by automatically controlling, but also inevitably there is security risk,
When manhole cover have personnel or material passes in and out, well lid cannot have movement, once control system breaks down or maloperation,
It will cause damages to well head construction personnel and material.
Utility model content
In view of the above technical problems, the utility model is intended to provide a kind of safety-type hydraulic automatic well lid, when by infrared
To when penetrating light curtain and detect that manhole cover have personnel or material to pass in and out, well lid cannot have movement, to ensure well head constructor
The safety of member and material.
For this purpose, technical solution used by the utility model is：A kind of safety-type hydraulic automatic well lid, including well lid, well
Lid mounting base and well lid automatic-opening mechanism, integrally formed with the installation towards outer wall protrusion on the inner wall of the well lid mounting base
Chamber, infrared emission light curtain is equipped in the installation cavity must not protrude well lid mounting base after the infrared emission light curtain installation
Inner wall.
The well lid automatic-opening mechanism includes hydraulic cylinder, lifting overturning seat, the well lid as a preferred embodiment of the above solution,
It is hinged on lifting overturning seat, hydraulic cylinder overturns opening after pushing well lid level to rise by lifting overturning seat again, in the liter
It is provided with safe mandril in the middle part of drop overturning seat, when well lid closing and horizontal lifting, the upper end of safe mandril is against in well lid
On wall, when well lid is overturn around hinge joint, the upper end of safe mandril is detached from well lid inner wall.Increase a safe mandril, safety roof
The upper end of bar is against on well lid inner wall, during Hydraulic Cylinder well lid, increases a supporting point, promotion gets up more to save
Power, while well lid is flipped back to play position-limiting action.
Further, the safe mandril TBE (threaded both ends), through nut check on lifting overturning seat, upper end is furnished with for lower end
Nut overstriking.Ready-made standard component, save the cost, and safe mandril upper end nut overstriking can be borrowed, end intensity is improved.
Further, the outer wall of the well lid mounting base is distributed along the circumference with several triangle reinforcing ribs, to increase well lid
The integral strength of mounting base.
The beneficial effects of the utility model：By increasing infrared emission light curtain in well lid mounting base inner wall, for detecting well
Whether mouth has construction personnel and material disengaging, to improve the safety of construction；Infrared emission light curtain hides installation, is not take up in well
Operating space, and can effective protection infrared emission light curtain.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the perspective view (not including well lid) of the utility model.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1 and Figure 2, a kind of safety-type hydraulic automatic well lid, it is mainly automatic by well lid 1, well lid mounting base 2, well lid
Opener 3 and infrared emission light curtain 4 form.
Integrally formed with the installation cavity 2a towards outer wall protrusion on the inner wall of well lid mounting base 2, installed in installation cavity 2a
After having infrared emission light curtain 4, infrared emission light curtain 4 to install, the inner wall of well lid mounting base 2 must not be protruded.
Well lid automatic-opening mechanism 3 is mainly made of hydraulic cylinder 3a, lifting overturning seat 3b, and well lid 1 is hinged on lifting overturning
On seat 3b, hydraulic cylinder 3a overturns opening, well lid automatic-opening mechanism after pushing well lid 1 is horizontal to rise by lifting overturning seat 3b again
3 is same as the prior art, and details are not described herein.It is provided with safe mandril 6 in the middle part of lifting overturning seat 3b, when well lid 1 is closed
And when horizontal lifting, the upper end of safe mandril 6 is against on 1 inner wall of well lid, when well lid 1 is overturn around hinge joint, safe mandril 6
Upper end is detached from 1 inner wall of well lid.
Preferably, safe 6 TBE (threaded both ends) of mandril, through nut check on lifting overturning seat 3b, upper end is furnished with for lower end
5 overstriking of nut.
In addition, the outer wall of well lid mounting base 2 is distributed along the circumference with several triangle reinforcing rib 2b.
