Abstract
The utility model provides a kind of well lid pressure test device, comprise the testing counter of frame top, described testing counter is provided with some blocks of arc parallels of the support well lid contacted with residual strain sensor, described arc parallels and testing counter are that packaged type is connected, pressure test head moving up and down is provided with above testing counter, be provided with the thrust unit promoting the movement of pressure test head in described pressure test crown portion, described pressure test head is fixed on fixed support.The utility model avoids floor in traditional measurement mode below well lid to the impact of survey data actual value, has good fixed effect; Structure is simple, and it is convenient to implement, and takes off easily when not using; There is good compliance for dissimilar test specimen, the detection of different test specimen can be met, convenient test.
Description
Technical field
The utility model relates to testing arrangement field, particularly relates to a kind of well lid pressure test device.
Background technology
Along with the develop rapidly of China's economy, China's infrastructure construction welcomes again a new cycle, and the market demand of well lid in urban planning and road construction is huge, but well lid is by rolling, and breakage happens occasionally, and causes road and installation security to decline.
Therefore, the well cover for sewer used in the market all needs to carry out supporting capacity test, following in order to reach the floor that GB to be emphasized etc. to require all to be provided with arc due to well lid, so on existing pressure test device, be out of shape the excessive or underproof well lid of residual strain when the pressure is exerted, with the floor of radian to conflict testing counter, cause test data inaccurate.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of well lid pressure test device.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of well lid pressure test device, comprise frame, be arranged on the testing counter of described frame top, be included in the middle of described testing counter and residual strain sensor is installed, the residual strain value display unit linked together with residual strain sensor is provided with in described testing counter one end, described testing counter is provided with some blocks of arc parallels of the support well lid contacted with residual strain sensor, described arc parallels and testing counter are that packaged type is connected, pressure test head moving up and down is provided with above testing counter, the thrust unit promoting the movement of pressure test head is provided with in described pressure test crown portion, described pressure test head is fixed on fixed support.
Preferably, described some blocks of parallels are combined into circle along well lid edge.
Preferably, be detachable installation between described fixed support and pressure test head.
Usefulness of the present utility model is, avoids floor in traditional measurement mode below well lid to the impact of survey data actual value, has good fixed effect; Structure is simple, and it is convenient to implement, and takes off easily when not using; There is good compliance for dissimilar test specimen, the detection of different test specimen can be met, convenient test.
Accompanying drawing explanation
Fig. 1 the utility model well lid pressure test device structural representation;
Fig. 2 the utility model well lid pressure test device well lid parallels structural representation.
In figure: 1 frame, 2 testing counters, 3 residual strain sensors, 4 parallels, 5 force value display unit, 6 fixed supports, 7 pressure test heads, 8 hydraulic feed devices.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
A kind of well lid pressure test device, comprise frame 1, be arranged on the testing counter 2 of described frame top, in the middle of described testing counter 2, residual strain sensor 3 is installed, described testing counter 2 one end is provided with the force value display unit 5 linked together with residual strain sensor, described testing counter 2 is provided with some blocks of arc parallels 4 of the support well lid contacted with residual strain sensor, above testing counter 2, be provided with pressure test moving up and down 7, be provided with the thrust unit 8 promoting the movement of pressure test head at described pressure test 7 top.
Adopt technique scheme, during specific works, as Fig. 1 will need the well lid horizontal positioned of testing intensity to parallels 4, pressure test 7 is at hydraulic pushing device 8 moved downward, and touch well lid and apply pressure to well lid, by parallels 4, pressure uniform pass to residual strain sensor 3, then on pressure-display device 5, show numerical value.
As shown in Figure 2, described arc parallels 4 can move on testing counter according to the size of well lid, circle is surrounded along well lid edge, well lid is held up, the arc floor of well lid bottom is avoided to touch testing counter, to meet the requirement of uniform force, described residual strain sensor contacts with parallels 4 all the time and connects.
