The advantages and features of the present invention will become more apparent in conjunction with the following description. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
Referring to fig. 1, the present embodiment provides a device for opening a well cover, which includes a tripod 4, a turntable 3, a supporting frame 2, an expansion rod 1 and a chain hook 6.
The well lid 5 shown in the figure is a heavy duty well lid with 2 open holes and the chain hook 6 is a chain with hooks at both ends. When the telescopic rod is used, two hooks at two ends of the chain hook 6 respectively penetrate into an opening hole of the well cover 5, and a chain ring in the middle of the chain hook 6 (a chain ring for halving a chain) is hung on a hook 7 at one end of the telescopic rod 1. The small well lid is usually provided with an opening hole only at the center of the lid, and when the chain hook 6 is used, only the hook at one end can be used, so that any chain ring is hung on the hook 7; the hooks at both ends can also be inserted into the same opening hole. The chain hook 6 is used for prolonging and expanding the hook 7, and an operator can operate the well lid opening device at the other end of the telescopic rod 1 in a vertical mode without half-squatting (horse-riding) for opening the well lid.
The three feet of the tripod 4 are of telescopic structures, the foot length is adjustable, the overall height of the tripod 4 can be conveniently adjusted, and the tripod can also adapt to a construction site with uneven bottom surfaces. Preferably, tripod 4 is iron or wood. When the tripod 4 is iron, the rotating disc 3 placed on the tripod can be fixed by welding.
As shown in fig. 2, the turntable 3 includes two parts, a circular rotary bottom groove and a tray. The bottom surface of the tray is provided with an annular bulge, the shape of the annular bulge is matched with that of the rotating bottom groove, the annular bulge can be embedded in the rotating bottom groove to push the tray, and the tray can rotate along the rotating bottom groove. Further, in order to reduce resistance to rotation of the tray, a plurality of balls may be provided in the rotary bottom groove. Preferably, the ball is filled between the rotary bottom groove and the annular protrusion.
Referring to fig. 2, in the present embodiment, the supporting frame 2 is a square box body, fixed on the tray of the turntable 3, and capable of rotating back and forth 360 ° along with the tray. The top of the support frame 2 is also provided with a support, one end of the connecting shaft 9 is provided with a nut, the nut connecting shaft 9 can be taken down and inserted into or taken out of the support, the nut is fastened, and the connecting shaft 9 is fixed on the support.
As shown in fig. 3, in order to obtain the highest possible hardness, the telescopic rod 1 is preferably a multi-section steel casing tube in this embodiment. One end of each section of sleeve (except the thinnest section of sleeve) is provided with a fixing screw 8, and when the fixing screw 8 is screwed down, the relative position between the two sections of sleeve can be fixed, so that the aim of keeping the current length of the telescopic rod 1 is fulfilled. An operator can automatically adjust the total length of the telescopic rod 1 according to specific requirements on a construction site. The telescopic rod 1 is also provided with a plurality of through holes with the diameter matched with the connecting shaft 9, the connecting shaft 9 can sequentially penetrate through one side of the bracket, any through hole in the telescopic rod 1 and the other side of the bracket, and the nut is fastened, so that the telescopic rod 1 can reliably rotate around the connecting shaft 9. When not using or changing the building site, pull down telescopic link 1, be convenient for very much accomodate and carry.
During the specific use, at first erect tripod 4 at appropriate distance apart from well lid 5, for the operating personnel uses, can be with the height adjustment of tripod 4 for the height that suits with operating personnel. Then, the fixing screws 8 are loosened, the telescopic rod 1 is opened to adjust the length of the telescopic rod, and then the fixing screws 8 are tightened to fix the sleeves of the telescopic rod 1 in pairs. Then the telescopic rod 1 is movably arranged on the supporting frame 2 through the connecting shaft 9. The method comprises the steps of hanging a chain ring of a chain hook 6 (if the field condition permits, the chain hook 6 is not used) on a hook 7, enabling hooks at two ends/one end of the chain hook 6 to penetrate through an opening hole in a well cover 5 and rotate, enabling the hooks to firmly hook the inner wall of the lower bottom surface of the well cover 5, then adjusting the length of a telescopic rod 1 again according to the weight degree of the well cover 5, enabling the telescopic rod 1 to be completely pulled out if the well cover 5 is heavy, and enabling the well cover 5 not to be completely pulled out if the well cover 5 is light. After the adjustment is completed, an operator can test the pressure first and then adjust the well lid according to the state of the well lid 5. The whole operation process needs to be stable, slow and accurate. After the well lid 5 is opened, rotate telescopic link 1, utilize carousel 3 to slowly remove well lid 5 and put down slowly after the flat vacant ground in next door, the operation of the well lid of the end opening.
The well lid opening device has the advantages of high speed, safety, labor saving, convenience in carrying, high universality and the like. During municipal pipeline operation, the traditional instrument of uncapping can only open general light-duty inspection shaft lid, rainwater grate etc. opens very big limitation when large-scale, heavy well lid, needs two at least people to cooperate, and the operation is wasted time and energy, has the potential safety hazard. The well lid opening device adopts a detachable assembly mode, can be rapidly assembled when in use, can be easily disassembled when not in use, and is convenient to transport and carry; by adopting a lever principle, the conventional light well lid can be opened, and large and heavy well lids can also be opened, so that the universality is strong; the opening process can be operated by only one person, the potential safety hazard when the opening is carried out in a conventional mode is avoided, the operation is rapid and safe, and the working efficiency is greatly improved.
It will be apparent to those skilled in the art that various changes and modifications may be made to the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
