Description
Technical field
The present invention relates to engineering system stake equipment such as a kind of water conservancy and hydropower, traffic harbour, highway, the railway system, concrete relevant with a kind of automatic punching stake machine.
Background technology
Road and bridge construction is especially greatly developed under the background of traffic in country at present, in the work progress at overhead railway, sky way, bridge pier, pier need be stood in the underground lithosphere admittedly, to guarantee the firm of bridge.Therefore must guarantee that in the formation in bridge pier hole the degree of depth in pier hole reaches in the lithosphere, so just need specialized apparatus punching down earthward, and the both sides or the cleaning that in the process of punching unnecessary earth/slurry and rubble are expressed to the hole go out, and punches downwards with continuous continuation.
Above-mentioned punching at present mainly is to utilize weight (being also referred to as Churn drill) to realize by punching stake machine, existing punching stake machine is mainly manual control, its structure includes frame, support, be installed on the motor on the support, the gearbox that links to each other with motor by shaft coupling, link to each other with output shaft of gear-box and be the reel of dead axle, with reel first fixed pulley separated by a distance, second fixed pulley that is higher than support, one wire rope and the weight that is connected in wire rope one end, the described wire rope other end is set around successively reels behind second fixed pulley and first fixed pulley and is fixed on the reel, and brake joystick and Clutch Control handle.Promote weight to certain altitude and make it prominently put free-falling, back and forth utilize tension weight churning kinetic energy impact extrusion soil layer or fractured rock pore-forming.Part disintegrating slag and mud are squeezed in the hole wall, and major part becomes mud or disintegrating slag, utilize and to draw slag tube or other method with outside the body refuse tap.And then put down reinforcing cage, concrete perfusion pile.So when needs drop hammer (Churn drill), need the loosen the clutch joystick, weight promptly can be from free-falling on second fixed pulley, in default position, hole, from top to bottom clash into, pulverize earth and slag charge, when needs are carried hammering blow pier hole once more or are cleared up pulverized earth or slag charge, then need pull at the dynamic clutch joystick by operating personnel, make reel just transfer weight is mentioned.For make in the hole can not descried weight to play drop point accurate, generally be that the wire rope middle part more than ground is a label, operating personnel judge according to the position of label whether the determining positions of weight is carried hammer or dropped hammer.
As shown in Figure 7, propose the hammer and two the important requirements of having dropped hammer in the present punch process:
1, according to stake hole shock surface hardness difference, (Fig. 7-a), it is highly little to carry hammer when shock surface hardness is low, and it is highly big then to carry hammer when hardness is high to determine the different hammer height h1 that carries;
2, the bottom, stake hole of dropping hammer the time can effectively be impacted shock surface and wire rope and guarantees that (Fig. 7-c), the pine that prevents to restrict causes that (Fig. 7-d) causes inclined hole, hole partially to askew hammer to certain force of strain.
Three phenomenons should avoiding in the punch process: 1, hammer is not fallen bottom, hole and is just effectively impacted and be pulled upwardly (promptly empty hammer phenomenon) by force, and this can cause the judder of whole stake machine, quickens the stake machine and damages, and causes a machine to be shifted and displacement retrodeviates the hole; 2, weight is fallen after bottom, hole impacts, wire rope do not have tension force or too pine cause that weight is crooked in bottom, stake hole, this state can cause inclined hole, (Fig. 7-d) takes place the situation of hole and card hammer partially; 3, weight is fallen after bottom, hole impacts, and reel is not by timely stall, and the rolling wire rope is too many, may cause wire rope to be jumped out from two fixed pulleys, or reel disorder cable, back-roll rope and wire rope eject accident such as hurt sb.'s feelings.
Two important requirements and three phenomenons that should avoid of carrying hammer in the above punch process and dropping hammer just require the operative employee accurately to grasp carrying the hammer and the time of dropping hammer, carrying hammer and dropping hammer in punch process all is the branch by solenoidoperated cluthes, incompatible realization, pulling Clutch Control handle makes solenoidoperated cluthes by being separated into engagement in full force and effect fully, and a time difference is arranged certainly.Weight is the movement of falling object when dropping hammer, and the fast and reel of speed is the quick rolling wire rope of slight resistance, and in sum, general personnel are difficult to hold the accurate control of carrying hammer, dropping hammer.
In addition, above-mentioned operation also has following shortcoming:
1, needs the pulling that the people constantly exerts oneself or return joystick and back and forth operate in the operating process, by 2 classes of work every day 16 hours, per punching in 10 seconds was once calculated, and working needed operating grip 11520 times in one day altogether, labour intensity is very big, can waste very much people's muscle power like this; Cause present punching stake machine operation worker to be ready to be engaged in this work because of too tired the few;
2, when operating personnel tired during to the needs rest, often need shut-down and influence construction speed;
3, because manually-operated can not be controlled as mechanical, need to have a rest, and tired operation makes the action easy deformation, the sky hammer phenomenon that easy formation is harmful, waste resource and the easy machine that damages; Or the loose situation of wire rope appears, at this moment wire rope just comes off from pulley easily, has influence on normally carrying out of next operation, also causes the skew in a hole easily, influences workmanship;
4, be extensive use of existing more than 20 year history of technology of manual punching stake piling both at home and abroad, it exists, and labour intensity is big, operation is difficult to accurately control and drive piles slow-footed shortcoming, and each producer endeavours to start automatic control technology always, because all restrictions, substantive progress is not arranged so far, as:
One, utilizes the mode of time to send to carry hammer and the signal that drops hammer is realized automatic control, because following two defectives cause empty hammer, askew hammer often to take place, and after beginning punching a few minutes because the time cumulative errors just increase can not continuous operation, reason one: the transmission of clutch mode is arranged in the punching stake machine, because fixed the hammer time of carrying, clutch can not definitely avoid skidding to take place in punch process, so it is just unequal to carry the hammer height at every turn; Reason two: because of carry hammer, the time of dropping hammer sets, so carry hammer height, height of the fall can change along with the speed of weight, and weight speed can be along with weight suffered resistance and changing when mobile in the stake hole, can influence weight suffered resistance when mobile in the stake hole as the mud thickness in the stake hole, so it is also inequality in punch process each time to carry hammer height, height of the fall.
Two, seek to cooperate the detection reel anglec of rotation accurately to locate the weight position with coaxial concentric installation rotary encoder of reel and PLC programmable logic controller, because the spool shaft of punching stake machine is the dead axle mode, and frequently move about reel meeting axially during punching, do not locate also and can't connect, so should not use this technology.
