Abstract
The utility model discloses a manhole booster device, which comprises a connecting rod, a protective sleeve, a connecting piece, an upper lug and a lower lug, wherein the protective sleeve is placed outside the connecting rod; the connecting piece is arranged at the front end of the protective sleeve; the protective sleeve and the connecting piece form a closed interval; baffle rings and springs are respectively arranged inside the protective sleeve from left to right; one end of the upper lug is fixed at the top end of the connecting rod; one end of the lower lug is fixed at the top end of the connecting piece; and the other ends of the upper lug and the lower lug are connected with each other through a pin shaft. When a manhole is opened or closed, the upper lug drives the connecting rod to move, so that the springs can be stretched or compressed; and when the manhole is closed, the spring is stretched, and the manhole can be easily opened by utilizing resilience force of the springs. The manhole booster device has the characteristics of simple structure, convenient usage, and capability of effectively reducing labor intensity of workers.
Description
Technical field
The utility model relates to a kind of booster device, says more specifically a kind of manhole booster device.
Background technology
Development along with science and technology, the manhole of installing on equipment has had the multiple manholes such as horizontal cover manhole, perpendicular lid manhole, rotary cap manhole, these manholes are when carrying out operation, when the manhole of equipment is opened in the vertical direction, the switch manhole is also more smooth, but when the equipment turnover operation that the rotary cap manhole is installed, because the switch manhole need to be opened with manpower, quite require great effort, when particularly manhole weight is heavier, each turnover all needs the workman to make power, has greatly increased the weight of workman's labour intensity.
Summary of the invention
For the problems referred to above, the problem that the utility model quasi-solution is determined is to provide a kind of simple in structure, easy to use, manhole booster device of reducing labor strength.
for achieving the above object, the utility model is by the following technical solutions: a kind of manhole booster device, it comprises connecting rod, protective sleeve, connector, upper journal and down journal, described protective sleeve is arranged in the outside of described connecting rod, the front end of described protective sleeve is provided with described connector, described protective sleeve and described connector form a closed interval, described protective sleeve inside is respectively equipped with baffle ring and spring from left to right, described upper journal one end is fixed on the top of described connecting rod, described down journal one end is fixed on the top of described connector, the described upper journal other end is connected by bearing pin with the described down journal other end.
As preferably, described bearing pin is rotating pin.
As preferably, the fixture of described upper journal one end and described connecting rod is bolt, and the fixture on described down journal one end and described connector top is bolt.
The beneficial effects of the utility model are: the utlity model has characteristics simple in structure, easy to use, as effectively to reduce labor strength.
