Abstract
The invention relates to a mechanical stone cracking method which relates to a wedge block set and an excavator quartering hammer. The wedge block set is composed of two outer wedge blocks and a middle wedge block, and the three wedge blocks are matched so that a cylinder can be formed. Different from a common excavator quartering hammer, the excavator quartering hammer is characterized in that the lower end face of a drill rod on the excavator quartering hammer is a plane, and is matched with the top face of the middle wedge block.
Description
Technical field
The present invention relates to one and split cubic meter of stone method, more specifically relate to a kind of machinery and split cubic meter of stone method, belong to technical field of engineering machinery.
Background technology
In various work progress, often need to carry out quarry work.Sometimes because when a variety of causes can not make the method blown up with dynamite, typically use digging machine disintegrating hammer impact, this method employs the machinery of relatively high power, and on softer rock, operation has higher operating efficiency.But when running into harder rock, inefficiency, excavation cost significantly increases.Tracing it to its cause is because rock, and ragstone particularly in blocks all exists the feature that compressive resistance is strong and resistance to tension is more weak, and quartering hammer is by making rock falls by outer firmly interior high force blow, has spent and has obtained little merit energetically.Another kind method relies on the small-sized stone machine that splits to make rock crack, then row excavation, moves, although the proper mechanical output owing to using of method is less, therefore efficiency is still lower.If can in conjunction with both advantage, use and a kind ofly utilize quartering hammer to impact chock to what make rock crack to split cubic meter of stone method, higher operating efficiency can be had.But there is no this big machinery that ragstone can be made to ftracture in flakes at present.
Summary of the invention
For solving the problem existing for the above-mentioned state of the art, the invention provides a kind of machinery and splitting cubic meter of stone method.
Described machinery is split cubic meter of stone method and is achieved by following technical proposals: its mechanical realization is made up of voussoir group and digging machine disintegrating hammer.Described voussoir group is by the identical outer voussoir of thin two of the thick top of following, and the conical center chock large with following point top forms, and three voussoirs agree with mutually, can be combined into a cylinder.Described digging machine disintegrating hammer and common digging machine disintegrating hammer difference are the lower surfaces of drill steel on this quartering hammer is a plane, agree with mutually with the end face of above-mentioned center chock, the diameter of crushing hammar drill rod can be consistent with the cylinder diameter that voussoir group forms here.
First on rock, accomplish fluently foramen lacerum during construction, the number in hole is depending on the length of ftracture rock, and aperture is a bit larger tham the diameter of voussoir group and drill steel, and hole depth is 5-10 times of aperture; The ratio in hole depth and aperture is exactly the draw ratio of voussoir, the larger voussoir of draw ratio puts on rock division strength when being subject to same downward force de frappe is larger, outer voussoir is put in the foramen lacerum accomplished fluently, adjust cracking direction, insert center chock, now the drill steel end face of quartering hammer is aimed at the end face of center chock, impact one by one, and increase the weight of hitting dynamics gradually, until rock crack.Because excavator and quartering hammer are all ready-made, implementing the present invention only needs to make several voussoir group, so it is a kind of scheme of investing little instant effect that a kind of machinery provided by the invention splits cubic meter of stone method.

Detailed description of the invention
Be described specifically below in conjunction with practical application, and non-limiting application of the present invention:
Embodiment 1
A kind of machinery splits cubic meter of stone method, and its mechanical realization is made up of voussoir group and digging machine disintegrating hammer.Described voussoir group is by the identical outer voussoir of thin two of the thick top of following, and the cylindrical center chock 2 large with following point top forms, and three voussoirs agree with mutually, can be combined into a cylinder.Described digging machine disintegrating hammer and common digging machine disintegrating hammer difference are the lower surfaces 6 of drill steel 5 on this quartering hammer 4 is planes, agree with mutually with the end face 3 of above-mentioned center chock, the diameter of quartering hammer 4 drill steel 5 can be consistent with the cylinder diameter that voussoir group forms here.
Rock just spend be less than Mohs 5 degree rock on construct time first on rock, accomplish fluently foramen lacerum 9, the number in hole is depending on the length of ftractureed rock, and aperture is a bit larger tham the diameter of voussoir group and drill steel, and hole depth is 5 times of aperture; The outer voussoir 1 that draw ratio is 5: 1 is put in the foramen lacerum 9 accomplished fluently, adjust cracking direction, direction between the mid point of two semicircular outer voussoirs is here exactly the cracking direction of rock, insert the center chock 2 that draw ratio is 5, now the drill steel end face 6 of quartering hammer is aimed at the end face 3 of center chock, impact one by one, and increase the weight of hitting dynamics gradually, until rock crack.
Embodiment 2
As described in Example 1 formation hardness (Mohs degree) be greater than 5 be less than 7 time, select draw ratio be 8: 1 voussoir group.
Embodiment 3
As described in Example 1 when formation hardness (Mohs degree) is greater than 7, selection draw ratio is the voussoir group of 10: 1. the quantity of foramen lacerum 9 can be encrypted if desired.
Embodiment 4 as embodiment 1,2, the voussoir group selected described in 3, two outer voussoirs 7 and center chock 8 mutually between be that plane is agreed with.
Claims (4)
1. a machinery splits cubic meter of stone method and it is characterized in that: be made up of voussoir group and digging machine disintegrating hammer, described voussoir group is by the identical outer voussoir of thin two of the thick top of following, the conical center chock large with following point top forms, and three voussoirs agree with mutually, can be combined into a cylinder.Described digging machine disintegrating hammer and common digging machine disintegrating hammer difference are the lower surfaces of drill steel on this quartering hammer is a plane, agrees with mutually with the end face of above-mentioned center chock.
2. a kind of machinery splits cubic meter of stone method and it is characterized in that as claimed in claim 1: first on rock, accomplish fluently foramen lacerum during construction, and the number in hole is depending on the length of ftracture rock, and aperture is a bit larger tham the diameter of voussoir group and drill steel, and hole depth is 5-10 times of aperture; The ratio in hole depth and aperture is exactly the draw ratio of voussoir, the larger voussoir of draw ratio puts on rock division strength when being subject to same downward force de frappe is larger, outer voussoir is put in the foramen lacerum accomplished fluently, adjust cracking direction, insert center chock, now the drill steel end face of quartering hammer is aimed at the end face of center chock, impact one by one, and increase the weight of hitting dynamics gradually, until rock crack.
