Abstract
The utility model discloses a well lid opening device. The well lid opening device comprises a support, a pinch bar, a hanging ring, pull chains and lifting hooks. The end of the pinch bar is connected to the top end of the support through a hinge, the hanging ring is connected with one ends of the two pull chains, and the other ends of the two pull chains are connected with the lifting hooks respectively. The pinch bar penetrates into the hanging ring. According to the well lid opening device, the lever principle is used for changing a traditional well lid opening and closing mode, a well lid can be opened easily by using the support as a fulcrum to apply upward force, so that time and labor are saved, and the broken probability of the well lid in the opening process is also lowered.
Description
Technical field
The utility model relates to a kind of use instrument, specifically, relates to a kind of well cover opening device.
Background technology
Progressively expansion along with our factory production capacity, construction project and Infrastructure increase, supporting water supply, the well head quantity of draining also increases thereupon, conventionally open manhole cover is to operate with well hook, the well hook arm of force is short, operating personal one-handed grip, only depend on the one-sided well lid that lifts to realize folding operation, the operating personal amplitude of bending over can reach 90 degree or low-angle more, such folding method of operation is time-consuming, effort, also there is certain potential safety hazard, as: the easy arm of operating personal is pulled, waist injury or instep injure by a crashing object, by well hook, pull the well lid well lid that also very easily weares and teares.
Utility model content
The technical matters that the utility model solves is to provide a kind of well cover opening device, has changed the mode of traditional unlatching, closed well lid, not only time saving and energy saving, but also reduces the possibility of well lid breakage when opening.
A well cover opening device, comprising: bearing, ripping bar, suspension ring, slide fastener and suspension hook; The end of described ripping bar is connected through the hinge on the top of described bearing, and described suspension ring connect one end of two described slide fasteners, and the other end of two described slide fasteners connects respectively described suspension hook, and described ripping bar is through in described suspension ring.
Further: described ripping bar comprises outside extra heavy pipe and is sleeved on the tubule of extra heavy pipe inside.
Further: described extra heavy pipe and tubule have tapped bore, on described tapped bore, screw rod is installed.
Further: also comprise suspension rod, described suspension ring are fixed on the middle part of described suspension rod, one end of two described slide fasteners is connected to the two ends of described suspension rod.
Further: the end of described suspension hook is flats.
Further: described bearing comprises equilateral 3-D triangle framework and plane steel plate, and described plane steel plate is welded on the top of described equilateral 3-D triangle framework.
Further: described bearing comprises equilateral 3-D triangle framework and curved plate, and described curved plate is welded on the top of described equilateral 3-D triangle framework.
1, the utility model utilizes lever principle to change the mode of traditional unlatching, closed well lid, and the bearing of take firmly gets final product light open manhole cover as fulcrum makes progress, not only time saving and energy saving, but also reduces the possibility of well lid breakage when opening.
2, the utility model well cover opening device make simple and easy, cost is low, open manhole cover is quick, can avoid that employee's arm when regular job is pulled, waist injury, shank is damaged or instep injures by a crashing object, guarantees that employee does not cause unexpected injury at work.
Accompanying drawing explanation
Fig. 1 is the planar structure schematic diagram of well cover opening device in the utility model;
Fig. 2 is the perspective view of well cover opening device in the utility model.
The specific embodiment
The possibility occurring in order to reduce above-mentioned potential safety hazard, makes the method that well cover opening device replaces using in prior art the open manhole cover of well hook.
As shown in Figure 1, be the planar structure schematic diagram of well cover opening device in the utility model; As shown in Figure 2, be the perspective view of well cover opening device in the utility model.
The structure of well cover opening device comprises: suspension rod 21, bearing 22, ripping bar 23, suspension ring 24, slide fastener 25, suspension hook 26; The end of ripping bar 23 is connected through the hinge on the top of bearing 22, and suspension ring 24 are fixed on the middle part of suspension rod 21, and ripping bar 23 is through in suspension ring 24, and one end of two slide fasteners 25 is connected to the two ends of suspension rod 21, and the other end of two slide fasteners 25 is connecting shackle 26 respectively.
The utility model also can directly connect one end of two slide fasteners 25 by suspension ring 24, and the other end of the two slide fasteners 25 respectively mode of connecting shackle 26 saves suspension rod 21.
The material of bearing 22 is reinforcing bar, and reinforcing bar is welded into equilateral 3-D triangle framework, equilateral 3-D triangle framework top welding plane steel plate or curved plate.Reinforcing bar materials are diameter 14mm and 10mm.Certainly, bearing 22 also can be selected other materials, and for example angle steel is welded, as long as can play point action.
Ripping bar 23 is selected materials as steel pipe, and arranging of slide fastener 25 can make the range of use of well cover opening device more flexible more greatly, is applicable to the spacing of different well lid eyelets, adjusts leeway larger.
When needs open manhole cover, bearing 22 is put in to well lid 10 other, the suspension ring 24 by ripping bar 23 through suspension rod 21 tops, suspension hook 26 is stretched into well lid 10 eyelet 11 above, utilize lever principle, take bearing 22 as fulcrum, upwards lift the end of ripping bar 23, can light open manhole cover 10.This opening ways is not only time saving and energy saving, but also it is damaged when opening to reduce well lid.
In addition, the mode that ripping bar 23 also can adopt socket joint to connect the steel pipe of two different thicknesses (caliber is different) is connected, and shortens the overall length of ripping bar 23 so that carry.Ripping bar 23 comprises outside extra heavy pipe and the tubule that is sleeved on extra heavy pipe inside, and the internal diameter of extra heavy pipe is slightly larger than the external diameter of tubule; Tapped bore is opened respectively at two ends at tubule, in one end of extra heavy pipe, opens the tapped bore onesize with tubule, in ripping bar 23 used time not, tubule is enclosed within extra heavy pipe, with a screw rod, screws in two tapped bore, and tubule is locked in extra heavy pipe; When using, tubule is pulled out in extra heavy pipe, with screw rod, by a connection of extra heavy pipe and tubule, lengthened ripping bar 23 and again extra heavy pipe, tubule have been fixed.
In order to meet ripping bar 23 different length needs, can on extra heavy pipe and tubule, open the tapped bore of different distance, convenient ripping bar 23 length that regulate, also can fix suspension ring by screw rod, the unlikely landing of suspension ring 24 while making open manhole cover, the while is the stressed position of adjustable suspension ring 24 on ripping bar also.
The end of suspension hook 26 is flats, is beneficial to clear up the foreign material in gap between well lid 10 and walling crib, the two loosening friction, use of the open manhole cover of being more convenient for of reducing by it.
