Description
The utility model is relevant with the construction of pile foundation engineering, and is especially relevant with the underground interior cutting of steel-pipe pile.
At present, the domestic various cutting machines that are used for steel-pipe pile cutting generally can only be used for steel pipe and cut outward.And after pile foundation construction finishes, before carrying out earth excavation, the steel-pipe pile more than the designed elevation must be cut off.Owing to be subjected to the restriction of existing equipment function, often can only take to excavate earlier the method for afterwards cutting, promptly earlier the earth around the stake pipe is successively excavated, and cut off until the designed elevation degree of depth being exposed to the outer stake pipe segmentation of pipe.But in the environment that the stake pipe stands in great numbers, be difficult to large tracts of land and adopt the mechanization operation, a large amount of work can only be finished by manpower, and not only working strength of workers is big, and work efficiency is also low especially, can't adapt to large-scale pile foundation engineering construction.Moreover, because pile crown cut by segmentation, can't regeneration, a large amount of steel are wasted, and have also therefore increased engineering cost.
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of steel-pipe pile underground cutter sweep.Utilize this device, can fundamentally the outer cutting mode of traditional pipe be changed into cutting mode in the pipe;
Providing a kind of can carry out the disposable equipment that cuts off to pile crown, and improves work efficiency with this.
A kind of device that can cut off complete pile crown according to designed elevation is provided, avoids because of adopting the waste of a large amount of steel-pipe piles that the outer cutting mode of segmentation causes, thereby reduce engineering cost.
For achieving the above object, the utility model has adopted following technical scheme:
The underground cutter sweep of a kind of steel-pipe pile, comprise mainly circumference cutting speed reducer structure that is made of motor, decelerator, planetary gear and the pneumatic pressure regulating device that constitutes the control loop of mainly being made up of the pneumatic element that comprises solenoid directional control valve, sequence valve and pressure-reducing valve and check valve, it is mainly by the fuselage supporting and positioning mechanism and be arranged at the described circumference cutting speed reducer structure on the single-revolution dish, pneumatic pressure regulating device and the pneumatic feeler mechanism of following respectively and constitute.
Compared with prior art, the utlity model has following remarkable result:
1. utilizing the utility model can change the outer cutting mode of traditional segmentation is cutting mode in whole section, the pile crown reproducible utilization, thereby reduced engineering cost significantly.
2. after utilizing the utility model to cut off fast and extracting the steel pipe pile crown, just can carry out the operation of extensive mechanization earthwork construction, its efficiency of construction can significantly improve.
3. adopt that ground remote control is underground to be cut automatically, alleviated labour intensity greatly; Again because it is easy and simple to handle reliable, thereby reduced specification requirement to the operator.
4. because support arm of the present utility model is that three groups of parallelogram lindages promptly adopt two six point location modes, and the setting of pinch roll in addition makes fuselage have the automatic capturing function, cutter sweep is located reliable and stable in the stake pipe, the positioning accuracy height.
5. owing to adopt the pneumatic profile copying technology of following, overcome the variation of the cutting distance that is caused by factors such as concrete pollutions because of stake pipe deviation from circular from or tube wall effectively, guaranteed the stability of cutting process ionic medium electric arc.
6. adopt air plasma as the cutting medium, not only cost is low, and safe and reliable.
7. adopt standardization combination design, the main body parts (except the rotary disk) of various models all have interchangeability, have therefore realized a tractor serves several purposes.
8. because decelerator speed ratio of the present utility model big (1: 2500), contour structure size is little, and therefore, complete machine has characteristics such as compact conformation, volume are little.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a mounting structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is a pneumatic control schematic diagram of the present utility model;
Fig. 4 is a diced system operation principle block diagram of the present utility model.
The underground cutter sweep of steel-pipe pile as shown in Figure 1 and Figure 2, comprise mainly circumference cutting speed reducer structure that is made of motor 1, decelerator 2, planetary gear 4 and the pneumatic pressure regulating device that constitutes the control loop of mainly being made up of the pneumatic element that comprises solenoid directional control valve 22 (being arranged in the control cabinet of ground), sequence valve 20 and pressure-reducing valve 19 and check valve 21, it is mainly by the fuselage supporting and positioning mechanism and be arranged at the described circumference cutting speed reducer structure on the single-revolution dish 3, pneumatic pressure regulating device and the pneumatic feeler mechanism of following respectively and constitute.
The support arm 5 that described fuselage supporting and positioning mechanism comprises the center cylinder 8 of double as fuselage, is made of three groups of parallelogram lindages; The bottom of described center cylinder 8 is provided with a terminal pad 10 that is connected with the drive rod 24 of the piston rod 11 of center cylinder 8 and support arm 5 respectively, thereby has realized the synchronous interaction of piston rod 11 and three groups of support arms 5 of center cylinder 8.
On the connecting rod 7 of the support arm 5 that the vertical axis with center cylinder 8 parallels, be respectively arranged with support claw 6 and pinch roll 9.Described support claw 6 is detachable, the replacing after being convenient to it and being worn.During making, support claw 6 and stake inside pipe wall 25 corresponding pawl faces can be made and the corresponding arc-shaped curved surface of its shape, and non-slip groove is set thereon, control the displacement that produces between support claw 6 and the tube wall 25 with this.
The described pneumatic feeler mechanism of following is mainly by following cylinder 12 and plunger 13 thereof, following roller 14 and the connecting pin 15 that is connected with plunger 13, cutting torch 17 and chuck 16 thereof constitute; Described cutting torch chuck 16 holders drop on the guide runner 23 that is connected as a single entity with described connecting pin 15, make described cutting torch 17 fuse by connecting pin 15 and the plunger 13 of following cylinder 12.Thereby realize plunger 13, follow being synchronized with the movement of roller 14 and cutting torch 17 threes, constant to remain between cutting torch 17 and the tube wall 25 predefined distance.
