Abstract
The utility model provides a manhole cover opening device, includes the cross arm, and the middle part of its characterized in that cross arm is connected with rings, and the one end of cross arm is equipped with crooked branch, and branch and rings are in the coplanar, and the one end of cable is connected with the triangle pull head, and the other end of cable passes rings and is connected with another triangle pull head, the utility model discloses during the use, it is downthehole and rotatory 45 earlier to insert opening of well lid with the triangle pull head, then with a lift by the stern subaerial in well lid one side, upwards lifts from the opposite side and to open the well lid, or two people lift up the well lid from the both ends of cross arm respectively, the utility model discloses have the security height, use shoulder strength to have an effect together by abdomen shoulder leg, avoid only drawing the well lid to cause pulled muscle by the pulling force, work efficiency is high, and it is convenient to handle to the condition that the well lid seal lock is dead, the well lid is marginal sticked with the base, install and small and exquisitely easily carry, be convenient for place on rushing to repair the vehicle, occupation space not after rolling the rope.
Description
Technical field
The utility model relates to instrument, a kind of well cover opening device being applicable to cable shaft or tap water well.
Background technology
It is understood that, urban electricity supply, water supply network is all embedded in underground, in order to control, the convenience of maintenance, power supply netting twine or water supply line keep at a certain distance away and are provided with observation maintenance well, that observes that maintenance well has that well lid arranges is concordant with ground, two cross open holes it are provided with symmetrically on existing well lid, well lid is opened during maintenance, open the cross-arm of the irony that instrument is one end buckle used, cleek is inserted in open hole, use lever principle open manhole cover, owing to the arm of force of this instrument is short and the fulcrum of iron is on well lid, so its active force upwards lifting well lid is little, it has the following disadvantages one is that Long-Time Service is big to well lid damage, unilateral open manhole cover is big to well lid damage；Two is that the strength needed is big, easily causes staff's joint sprain；Three to be on well lid efficiency low, to well lid hole plug, enter the things such as mud between well lid edge and pedestal after be difficult to open.
Summary of the invention
The purpose of this utility model is contemplated to overcome the deficiencies in the prior art, it is provided that a kind of operating efficiency is high, active force well cover opening device little, undamaged to well lid.
The technical solution adopted in the utility model is:
A kind of well cover opening device, including cross-arm, it is characterised in that the middle part of cross-arm connects suspension ring, one end of cross-arm is provided with the pole of bending, with suspension ring in the same plane, one end of drag-line is connected pole with triangle pull head, and the other end of drag-line is connected through suspension ring with another triangle pull head.
Triangle pull head described in the utility model is flat isosceles triangle, and the centre on one of them limit is provided with draw ring, and the two ends of drag-line are connected with triangle pull head through draw ring respectively.
Pole described in the utility model and cross-arm are hollow pipe, and pole is the extension of cross-arm, pole and the rectangular bending of cross-arm.
Suspension ring described in the utility model are connected with cross-arm through bearing or sliding sleeve so that it is can be different angles from pole, facilitate the unlatching of well lid.
The utility model use time, first by triangle pull head insert well lid open hole in and rotate 45 °, then a pole is bearing on the ground of well lid side, is lifted up being opened by well lid from opposite side；Or two people from the two ends of cross-arm, well lid is lifted respectively, it is high that the utility model has security, uses shoulder strength can have an effect together with waist abdomen shoulder leg, it is to avoid only to draw well lid to cause pulled muscle by pulling force；Operating efficiency is high, blocks for well lid hole, well lid edge processes when affixing with pedestal and facilitates；Device is small and exquisite portable, it is simple to be placed on recovery vehicle, is not take up space after being rolled by rope.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further described:
nullAs described in Figure，A kind of well cover opening device，Including cross-arm 1，It is characterized in that the middle part connection of cross-arm has suspension ring 2，One end of cross-arm 1 is provided with the pole 3 of bending，Pole 3 is with suspension ring 2 in the same plane，One end of drag-line 5 is connected with triangle pull head，The other end of drag-line is connected through suspension ring with another triangle pull head 4，Triangle pull head is flat isosceles triangle，The centre on one of them limit is provided with draw ring，The two ends of drag-line are connected with triangle pull head through draw ring respectively，Pole and cross-arm are hollow pipe，Pole is the extension of cross-arm，Pole and the rectangular bending of cross-arm，Suspension ring are connected with cross-arm 1 through bearing or sliding sleeve 6，Making it can be different angles from pole，Facilitate the unlatching of well lid，During use，In first triangle pull head 4 is inserted the open hole of well lid and rotate 45 °，Then a pole is propped up 3 to hold on the ground of well lid side，It is lifted up being opened by well lid from opposite side；Or two people from the two ends of cross-arm 1, well lid is lifted respectively, it is high that the utility model has security, uses shoulder strength can have an effect together with waist abdomen shoulder leg, it is to avoid only to draw well lid to cause pulled muscle by pulling force；Operating efficiency is high, blocks for well lid hole, well lid edge processes when affixing with pedestal and facilitates；Device is small and exquisite portable, it is simple to be placed on recovery vehicle, is not take up space after being rolled by rope.
