Technical field
The present invention relates to a kind of CFG pile foundation construction and abolish the special mechanism of pile crown.
Background technology
During the roadbed of special line for passenger trains and high-speed railway is built, in order to prevent subgrade settlement, in the roadbed bottom, be provided with pile foundation a large amount of, become low-grade filling concrete with cement, flyash and rubble blunge, be called the CFG stake.According to the technique of design, after CFG stake casting complete sclerosis, its pile crown need to be cut away, reach the absolute altitude of regulation, so that pour into a mould pile cover thereon.According to traditional technique, the pile crown of CFG stake is with manually being removed, time-consuming taking a lot of work, and affect project progress and construction quality, be badly in need of thereby become in the CFG pile driving construction technological problems solved.
The cutter sweep of the CFG stake of prior art is used motor to drive cutting blade to implement cutting, device adopts the carrying of track column support type, agravic balance, during actual the use due to unbalance loading, need to mass be installed in the position relative with drive motors, make the volume of device, weight larger; Owing to will circular orbit being installed at the pile foundation position, pile foundation partly must be leveled up in addition, increase geotechnological workload.
Summary of the invention
The technical problem to be solved in the present invention is: the pile crown cutter sweep that a kind of CFG stake is provided, mass need to be installed make device volume, weight larger to overcome unbalance loading that prior art exists, and at the pile foundation position, circular orbit is installed, the deficiencies such as geotechnological workload are partly leveled up, increased to pile foundation.
The technical solution adopted for the present invention to solve the technical problems is: it comprises cutter sweep support, cutting mechanism and cooling device, be provided with cutting blade cantilever lever, the first cantilever lever, the second cantilever lever, center convolution and support on the cutter sweep support, an end of cutting blade cantilever lever, the first cantilever lever, the second cantilever lever respectively with the center convolution support and connection; Cooling device is arranged on the second cantilever lever.
On the cutting blade cantilever lever, cutting mechanism is installed, cutting mechanism comprises drive motors, feed screw mechanism and cutting blade.The feed screw mechanism is to realize feed by spiral integrated moving drive motors and cutting blade.
Gravitational equilibrium driving wheel, spiral hold-down mechanism are installed on the first cantilever lever.
Gravitational equilibrium castor, spiral hold-down mechanism and cooling water tank are installed on the second cantilever lever.
Angle between cutting blade cantilever lever and the first cantilever lever is 120 °.
Angle between first round cantilever lever and the second cantilever lever is 30 °～120 °.
The lower end that center convolution supports adopts the tapered rod structure.
Cooling device adopts cooling water tank supply water cooling to cutting blade.
Center convolution supports can regulate the up and down distance of cutting blade with respect to the CFG stake, makes the working depth of cutter sweep adjustable up and down.The bottom that center convolution supports is a cone, for center, fixes.The cutting blade cantilever lever is for installing the feed screw mechanism of drive motors and drive motors, the feed screw mechanism of drive motors is for being fixedly connected with cutting blade, the first cantilever lever and the second cantilever lever all are equipped with gravitational equilibrium castor and spiral hold-down mechanism thereof, together form bikini with center convolution and support.The first cantilever lever and the second cantilever lever are positioned at the other end with respect to the cutting blade cantilever lever, and the angle between the first cantilever lever and the second cantilever lever can be between 30 ° to 120 °; The gravitational equilibrium castor is arranged on the bottom of the first cantilever lever and the second cantilever lever, by distance and the thrust of spiral adjustment and CFG stake side; Castor can forward rotate along CFG stake cutting planes, can not move up and down.
The present invention uses motor to drive cutting blade, and the CFG stake is carried out to the hoop cutting; Whole cutter sweep adopts longitudinal center's carrying, symmetrical expression castor compression type gravitational equilibrium, solve the agravic balance of original device and used the circular orbit column to support the problem of bringing, have and use safety, assembling and disassembling convenient, fast, the advantage of high efficiency, can fundamentally solve the technique difficult problem of broken of CFG stake.
The accompanying drawing explanation
Fig. 1 is the front view of CFG pile head cutter sweep schematic diagram of the present invention.The real work position of this device is that illustrated left end is under upper, right-hand member is.
Fig. 2 is the side view of CFG pile head cutter sweep schematic diagram of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
The present invention is comprised of cutter sweep support 2, cutting mechanism 3, cooling device 1.Cutter sweep support 2 comprises can regulate that upper and lower (for structure illustrated in Figure 1, " up and down " refers to " left and right "; Other relates to the content of " up and down " position, all with) center convolution of distance supports 2-3 and is arranged on center convolution and support the cutting blade cantilever lever 2-1 that is mutually certain angle on 2-3, three cantilever levers of the first cantilever lever 2-2, the second cantilever lever 2-4.The bottom that center convolution supports 2-3 is a cone, for center, fixes.Cutting blade cantilever lever 2-1 is equipped with cutting mechanism 3, cutting mechanism 3 comprises drive motors 3-1 and feed screw mechanism 3-2 and cutting blade 3-3, the first cantilever lever 2-2 is equipped with gravitational equilibrium castor 2-2-1 and spiral hold-down mechanism 2-2-2, the second cantilever lever 2-4 is equipped with gravitational equilibrium castor 2-2-1, spiral hold-down mechanism 2-2-2 and cooling water tank, together forms bikini with center convolution and supports.The first cantilever lever 2-2 and the second cantilever lever 2-4 are positioned at the other end with respect to the cutting blade cantilever lever, and the angle between the first cantilever lever 2-2 and the second cantilever lever 2-4 can be between 30 ° to 120 °; Distance and thrust with spiral adjustment and CFG stake side; Gravitational equilibrium castor 2-2-1 can forward prolong CFG stake cutting planes and rotate, and can not move up and down.
Drive motors 3-1 selects interchange 2 utmost point asynchronous machines of 1.5KW, and cutting blade 3-3 selects the diamond cutter of 250 millimeters of diameters; Angle between the first cantilever lever 2-2 and the second cantilever lever 2-4 is selected hexagonal angle.On the second cantilever lever 2-4, a cooling water tank is installed, and corresponding water pipe and water valve, as cooling device 1 use.
Before CFG pile head cutter sweep is installed, need to determine substantially the end face center of CFG stake, bore a hole in center with electric hammer, for the cone of mounting center spiral support 2-3; Regulating center support spiral 2-3 makes the height of cutting blade 3-3 in place; And the gravitational equilibrium castor 2-2-1 adjustable screw on the first cantilever lever 2-2 and the second cantilever lever 2-4 is unclamped, screw gravitational equilibrium castor 2-2-1 adjustable screw after locating and compress gravitational equilibrium castor 2-2-1.
The feed screw mechanism 3-2 regulated on cutting blade cantilever lever 2-1 makes cutting blade 3-3 in place, restart motor enforcement cutting after opening cooling water valve, shake feed screw mechanism 3-2, make cutter go deep into the CFG stake and meet the requirements of the degree of depth, again along Plane Rotation CFG pile head cutter sweep, make blade along pile body ring cutting one week, reach the purpose of cutting.
