Construction cost.
As above conceive, technical solution used by the utility model technology is: a kind of for recycling grabbing for concrete well
Tool, it is characterised in that: it is arranged in a crossed manner by two pieces of irregular arc plates and by rotation axis connection form a bridging；It is described
Hole for hoist is formed at the top of every piece of arc plate, middle part is formed with multiple adjusting bolt shaft holes, bottom connection arc stiffener plate；It is described every
Block arc stiffener plate both ends are respectively provided with ram's horn.
The adjusting bolt shaft holes of two 30mm are opened at the 3/4 and 4/5 of above-mentioned every piece of arc plate.
The arc length of above-mentioned arc plate is 500mm.
Above-mentioned arc stiffener plate is made of two blocks of arc-shaped steel plates, is formed with and bridging in the middle part of every piece of curved plate
The bolt hole of arc plate connection.
Above-mentioned ram's horn is arc panel, welds multiple rows of steel nail thereon and wedges rubber pad.
The radian of above-mentioned ram's horn is consistent with the radian of concrete well inside pipe wall.
The utility model has the following beneficial effects:
1, the utility model structure is simple, production selection is convenient, cost of manufacture is within 1000 yuan.
2, the utility model can quickly and conveniently catch concrete well from dewatering well, repeatedly return to can reach
Receive the purpose for reusing concrete well.
3, the utility model is adaptable, and the angle of bridging can be adjusted flexibly according to concrete well and its weight and size
Degree.
4, the utility model is light-weight, is convenient for site operation application.
5, utility model works are high-efficient, and a Ge Liang people shift and a set of equipment can carry out.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the plan view of ram's horn；
Fig. 3 is the elevation of ram's horn.
Fig. 4 is the usage state diagram of the utility model.
Specific embodiment
It is as shown in the figure: it is a kind of for recycling the gripping apparatus of concrete well, by two pieces of 2mm thickness, the irregular circular arc of 200mm wide
5, two pieces of arc stiffener plates 3 of a bridging of steel plate composition and four ram's horns 1 form.
1, the arc length of every piece of circular arc steel plate is 500mm, respectively opens two 30mm's at the 3/4 of circular arc steel plate and 4/5
Bolt shaft holes to change the supporting point of bridging angle, in bolt shaft holes insertion 30mm high-strength bolt as power transmission point rotation axis 4,
Therefore according to the position of the rotation axis of the different-diameter adjusting apparatus of concrete well.Simultaneously in the top of every block of circular arc steel plate
The hole for hoist 6 of 30mm is opened, hole for hoist 6 is that lifting point generates tension, and the pressure that tension passes to more greatly ram's horn is bigger.In addition every
A 20mm bolt hole insertion high-strength bolt 2 is respectively opened in the lower end of block circular arc steel plate and arc stiffener plate 3 connects.
2, every piece of arc stiffener plate 3 is made of the arc-shaped steel plate of two pieces of 2mm thickness, 150mm wide, arc length 150mm,
20mm bolt hole is formed in the middle part of arc-shaped steel plate, the circular arc steel plate of bridging is inserted between two blocks of arc-shaped steel plates of stiffener plate
And connected by the high-strength bolt 2 and arc stiffener plate 3 of 20mm in insertion bolt hole, high-strength bolt 2 is used as stress axis, arc
Stiffener plate is as stress point.
3, the steel plate of four ram's horns 1 200*200, the 5mm thickness curves an arc panel, the radian of the arc panel and mixed
The radian of solidifying soil well casing inner wall is consistent, and three row 50mm steel nails 9 are welded above arc panel and wedge 2mm rubber pad 8, four ram's horns
It is respectively welded at two pieces of arc stiffener plate both ends.Four ram's horns and concrete well tube wall share four contact surfaces, pass through work
Firmly stretching tube wall is as the main stress point to lift concrete well.
The principle of active force and reaction force is utilized in the utility model, transmits the force to ram's horn by bearing 4, makes ram's horn
Buffer brake is formed between concrete well tube wall, surface generates stiction.Since concrete well is non-fine concrete
Pipe, ram's horn and well casing contact surface produce larger pressure by the acting in opposition of scissors, so that frictional force between the two increases,
When the friction sum between gripping apparatus and concrete well tube wall is greater than concrete well weight and with the frictional force of soil, i.e.,
Well casing can be lifted.
When using the utility model, suspender is put into the hole for hoist of bridging first and penetrates hanging belt 7, then reversely cutting
The ram's horn of knife support is put into lifting concrete well, is held out against concrete well tube wall by the reaction force of bridging, is used jack
Or other machinery gradually hang out concrete well.
The utility model is not limited to embodiments described above.Above the description of specific embodiment is intended to describe
With illustrate the technical solution of the utility model, it not is restrictive that above-mentioned specific embodiment, which is only to illustrate,.Not
It is detached from the case of the utility model aims and scope of the claimed protection, those skilled in the art are practical new at this
The specific transformation of many forms can be also made under the enlightenment of type, these are belonged within the protection scope of the utility model.
