Description
Technical Field
The application relates to the field of automatic construction equipment of building piles, in particular to automatic construction equipment of carrier piles.
Background
The carrier pile is a new pile type with quick development and extensive application in recent years, and compared with the conventional pile type, it has the advantages of high bearing capacity, extensive application range, small pile hole depth and low cost, etc., and its main core is that the bottom of pile hole is filled with filling material in batches, and the pile hole is rammed by means of heavy hammer until a certain quantity (generally 1.2m 3 ) The filling material of the pile hole is rammed and compacted at the bottom of the pile hole to form an enlarged head; under the soil squeezing effect of the enlarged head, a compacted soil body which is outwards diffused along the enlarged head and an impact soil body are formed in the soil layer, so that extremely high bearing performance can be provided for the formed pile body; and the anti-pulling ribs in the enlarged footing can also realize the improvement of the anti-pulling performance of the carrier pile in the construction process.
One key construction node in the construction process of the carrier pile is the forming quality of the enlarged head, in the existing construction standard, the enlarged head is required to meet the three-click penetration standard, and the quantitative feeding of each batch of materials in the construction process also plays a key role in the whole construction progress.
For example, in the chinese patent with application number CN202110662055.9, an automatic multi-equipment high-efficiency construction method for pile body non-soil-squeezing carrier pile is proposed, which requires that the total filler amount of the material fed into pile holes is 1.2 cubic meters, and the set amount of each batch of filler is 0.01-0.3 cubic meters; and when the automatic filling ramming is carried out, whether the filling amount of the next step is larger than the set amount or smaller than the set amount is judged according to the sinking depth of the rammer.
For example, in the chinese patent with application number CN202110928495.4, a method for automatically constructing a deep dynamic compaction composite foundation is proposed, and when automatic packing compaction is performed, the automatic conveying device is required to convey a set quantity of packing of 0.1-1 cubic meter per batch; and the ramming penetration degree measured during the ramming of the heavy hammer is compared with the design penetration degree, and the next step is to continuously convey the set amount of filling materials or not.
That is, in the existing carrier pile automatic construction methods with high automation degree, the quantitative filling amount of the filling conveying device is used as a key parameter to be implanted into an automatic construction flow, so that the automation, the digitalization and the high-precision quality control of the carrier pile construction can be realized, the most suitable choice is a conveying belt in the aspect of building filling conveying at present, and the total conveying amount can be controlled by controlling the conveying time of the conveying belt under the condition that the running speed of the conveying belt is constant.
However, in actual construction, the applicant finds that, because the fillers filled into the carrier piles are generally dry and hard concrete, cement sand mixture, bentonite and the like, after the fillers are piled up in the hopper for feeding the conveyor belt, the fillers positioned at the receiving part of the hopper are extremely easy to agglomerate or block due to the gravity of the upper filler and the extrusion action of the inclined side wall of the hopper on the lower filler, especially at the discharge hole at the minimum opening end, the amount of the fillers actually falling into the conveyor belt by the hopper is reduced, even no fillers fall into the hopper, so that in the actual automatic feeding process, the feeding amount per unit time is inconsistent, and the feeding amount under the set time cannot reach the preset standard, which affects the quality control precision of the carrier pile construction and the consistency of the final pile forming quality.

The hopper 3 is funnel-shaped with a big top and a small bottom.
And referring to fig. 1 and 2, the chassis 1 is provided with:
and the high-level bracket 5 is used for carrying out high-level support on the lifting rope 23.
The belt side heightening mechanism 6 is used for increasing the loading height of the ascending section of the conveying belt 4.
The baffle plate 71 and the lifting driving piece 72 for driving the baffle plate 71 to lift are arranged at one end of the conveying belt 4 far away from the hopper 3; wherein, chassis 1 erects two guide rails of vertical setting in the top of conveyer belt 4, and striker plate 71 slides and sets up in the guide slot of two guide rails, and lift driver 72 is established to the pneumatic cylinder and invertedly installs between two guide rail tops, and the piston rod and the striker plate 71 rigid coupling of pneumatic cylinder.
The material height monitoring mechanism is used for monitoring the material level height of the conveyer belt 4 at the position of the baffle plate 71.
The signal input end of the quantitative controller is electrically connected with the material height monitoring mechanism, and the signal output end of the quantitative controller is electrically connected with the lifting driving piece 72; when the material level height detected by the material level monitoring mechanism is equal to the preset material level height, the quantitative controller controls the lifting driving piece 72 to drive the material baffle 71 to be lifted; when the material level detected by the material level monitoring mechanism is smaller than the preset material level, the quantitative controller controls the lifting driving piece 72 to drive the material baffle plate 71 to abut against the ascending section of the conveying belt 4.
A timer for recording the accumulated time length of the lifting state of the striker plate 71.
The signal input end of the main controller is electrically connected with the timer, and the signal output end is electrically connected with the conveyer belt 4 and the winch 21; when the accumulated time length recorded by the timer is equal to the set time length of the material conveying, the master controller controls the conveyer belt 4 to stop and controls the winch 21 to lower the heavy hammer 22.
Therefore, when the automatic construction of the carrier pile is carried out, the feeding time length of single batch of fillers is set, the corresponding material level height of the conveying belt 4 is set, and then the conveying belt 4 is controlled to be started through the master controller, so that the fillers falling from the hopper 3 are fed into the pile hole. In this process, when the filler on the conveyor belt 4 is conveyed to the position of the baffle plate 71, the material height monitoring mechanism monitors the material height on the conveyor belt 4 at the position, and when the instantaneous material height on the conveyor belt 4 is equal to the preset material level height, the quantitative controller controls the lifting driving piece 72 to drive the baffle plate 71 to lift, and the filler passes through the lower part of the baffle plate 71 and falls into the pile hole, and at the same time, the timer starts to count time.
Along with the continuous progress of automatic filling, when the material height monitoring mechanism monitors that the instantaneous material height on the conveyer belt 4 is smaller than the preset material level height, the probability of the phenomenon is larger mainly in the initial material conveying stage and when the lower end of the hopper 3 is blocked, at the moment, the quantitative controller controls the lifting driving piece 72 to drive the baffle plate 71 to move downwards to be abutted against the conveyer belt 4, and the timer stops timing; the continuously transported fillers on the conveyor belt 4 are piled up on one side of the baffle plate 71 close to the hopper 3 until the height of the materials at the position is equal to the preset height of the material level, the quantitative controller controls the lifting driving piece 72 to drive the baffle plate 71 to be lifted to the preset height of the material level, and at the moment, the timer continues to count time, and the fillers which meet the preset height of the material level fall into the pile hole beyond the baffle plate 71.
Until the accumulated time length of the timer reaches the set time length of the material conveying, the master controller controls the conveyer belt 4 to stop and controls the winch 21 to lower the heavy hammer 22 for tamping, at the moment, the amount of the filler conveyed into the pile hole by the conveyer belt 4 accords with a preset value, the amount of the filler conveyed into the pile hole by each batch of the conveyer belt 4 can be always ensured to meet the set value before each tamping, accurate judgment and high-precision execution of various construction parameters in the automatic construction process of the carrier pile are facilitated, the flexibility is higher, different requirements of different batches of filler amounts in the construction process of the carrier pile are met, the high-precision construction process control in the automatic construction process of the carrier pile can be realized, and the consistency of pile foundation quality in the construction process of multiple pile positions is ensured.
In the concrete implementation, as the filler is mainly dry and hard concrete, tri-clay and the like with certain viscosity, the fault tolerance and applicability of the filler under the condition need to be considered when the material height monitoring mechanism is arranged, therefore, referring to fig. 1 and 2, the material height monitoring mechanism comprises a monitoring plate 81 hinged above a conveying belt 4, the axis of a hinged shaft of the monitoring plate 81 is arranged orthogonal to the conveying direction of the conveying belt 4, and a flexible protective cover (not shown in the figure) is arranged at the hinged part of the monitoring plate 81 and a bottom plate so as to reduce the influence of the filler on a rotating part of the monitoring plate; the monitoring plate 81 is disposed on a side of the dam plate 71 near the hopper 3, and the monitoring plate 81 is disposed obliquely downward in the conveying direction of the conveyor belt 4. Meanwhile, a pressure sensor 82 positioned right above the monitoring plate 81 is fixed on the chassis 1; when the monitoring plate 81 is turned up to collide with the pressure sensor 82, the bottom end of the monitoring plate 81 is located on the horizontal plane of the preset height of the material level. And the monitoring board 81 is further provided with a loading member 83 for enabling the monitoring board 81 to have a downward overturning trend, and the loading member 83 can be a balancing weight fixedly connected to one side of the detection board away from the conveying belt 4 or a torsion spring arranged on a hinge shaft between the monitoring board 81 and the chassis 1.
After the arrangement, when the conveyer belt 4 conveys the filling material, the monitoring plate 81 is abutted against the upper layer of the filling material and overturns on the chassis 1 along with the difference of the material level height of the filling material, and if the material level on the conveyer belt 4 is lower than the material level preset height, the monitoring plate 81 cannot be abutted against the pressure sensor 82, and the pressure sensor 82 does not output signals. If the material level on the conveyor belt 4 is not less than the preset material level, the pressure sensor 82 is interfered by the monitoring board 81 to send out an electric signal; when the feeding level of the conveyor belt 4 is higher than the preset level, and the monitoring plate 81 cannot be turned over continuously because the monitoring plate 81 is limited by the pressure sensor 82, the monitoring plate 81 scrapes more filler on the conveyor belt 4, so that the filling level passing through the lower part of the baffle plate 71 is equal to the preset level, and the pressure sensor 82 can still send out an electric signal. Therefore, whether the height of the filling material on the conveying belt 4 reaches a preset value can be judged according to whether the pressure sensor 82 outputs signals, and accurate monitoring of the feeding height of the conveying belt 4 by the material height monitoring mechanism is realized.
To further clarify the control logic of the application in controlling the amount of filler in the conveyor belt 4, referring to fig. 3, the dosing controller comprises:
A signal receiving module for receiving the electric signal of the pressure sensor 82 and outputting the electric signal;
the control module is in communication connection with the signal receiving module; when the signal receiving module receives the electric signal, outputting a first control signal; outputting a second control signal when the signal receiving module does not receive the electric signal;
the first execution module is used for receiving the first control signal output by the control module, controlling the lifting driving piece 72 to start so as to drive the striker plate 71 to lift away from the conveyor belt 4, and controlling the timer to start timing;
the second execution module is used for receiving the second control signal output by the control module and controlling the lifting driving piece 72 to start so as to drive the striker plate 71 to move downwards to abut against the conveyor belt 4, and simultaneously controlling the timer to stop timing.
Like this, the monitor plate is in the high in-process of material loading level on monitoring conveyer belt 4, when the monitor plate contradicts pressure sensor 82, the thick coincidence preset value of filler on the characterization conveyer belt 4, pressure sensor 82 outputs the signal to signal receiving module, this signal is transmitted to control module again, control module outputs first control signal in order to control first execution module work, specifically lift driver 72 drive striker plate 71 lifting is kept away from conveyer belt 4 and the time-recorder starts the timing, the filler that accords with preset thickness at this moment carries in the stake hole from striker plate 71 below, the time-recorder is accumulated the time-recorder to the transport duration that accords with the filler of preset thickness.
When the monitoring plate does not abut against the pressure sensor 82, the thickness of the filling material on the conveyer belt 4 does not reach the standard, the signal receiving module does not receive an electric signal, the control module outputs a second control signal to control the second execution module to work, specifically, the lifting driving piece 72 drives the material blocking plate 71 to move downwards to abut against the conveyer belt 4 and the timer stops timing, so that the material blocking plate 71 blocks the filling material on the conveyer belt 4, when the filling material on the conveyer belt 4 is accumulated to push the material blocking plate 71 to abut against the pressure sensor 82, the first execution module is controlled to execute the action again until the accumulated timing of the timer reaches the preset material conveying duration, the timer outputs a signal to the total controller, the total controller controls the conveyer belt 4 to stop, and controls the winch 21 to lower the heavy hammer 22 to tamp the filling material, and thus high-precision control of each batch of seasoning amount can be realized.

By turning the adjusting bolt 213, the degree of extension of the tension spring 214 can be changed, thereby adjusting the degree of abutment of the abutment roller 212 against the hoist rope 23.
Considering that the transportation cost is extremely high when construction equipment is transferred in actual construction, the high-level bracket 5 which most influences transportation convenience can be set to be adjustable or detachable, specifically, referring to fig. 1 and 7, the high-level bracket 5 comprises a lower upright post 51 and an upper upright post 52 which are hinged with each other, one end of the upper upright post 52, which is far away from the lower upright post 51, is provided with a guide component for guiding the lifting rope 23, and a locking component for locking the upper upright post 52 and the lower upright post 51 in a collinear state is arranged between the upper upright post 52 and the lower upright post 51; the lower upright post 51 is hinged on the chassis 1, one end of the lower upright post 51, which is close to the upper upright post 52, is hinged with a telescopic rod 53, and one end of the telescopic rod 53, which is far away from the lower upright post 51, is hinged with the chassis 1; the hinge shaft of the lower upright 51 and the chassis 1 and the hinge shaft of the upper upright 52 and the hinge shaft of the telescopic rod 53 are parallel but orthogonal to the hinge shaft of the upper upright 52 and the lower upright 51, and the telescopic rod 53 is provided with an adjusting component for locking the total length of the telescopic rod at a set value. In actual setting, telescopic link 53 is sleeve pipe 531 and inserts the inserted bar 532 in sleeve pipe 531, and adjusting part sets up to pin 533, has all been offered the jack that pegging graft the adaptation with pin 533 on inserted bar 532 and the sleeve pipe 531 correspondingly, and the inserted bar 532 tip articulates on the base, and sleeve pipe 531 tip rigid coupling has hinge ear 535, and the one end that upper column 52 kept away from lower column 51 and the one end that lower column 51 is close to upper column 52 all rigid coupling have the hinge seat 536 with hinge ear 535 adaptation, and hinge ear 535 passes through the bolt and installs on hinge seat 536 and realize the articulated of both. And a plurality of ladders 56 are fixedly connected on the same side of the upper upright post 52 and the lower upright post 51.
Thus, before the carrier pile is constructed, the upper upright 52 is turned over on the lower upright 51 to make the upper upright 52 and the lower upright 52 collinear, then the hinge lugs 535 at the end of the sleeve 531 are mounted on the hinge seats 536 of the upper upright 52, then the lower upright 51 is turned over on the chassis 1 to be vertical, the insert rod 532 slides in the sleeve 531 to automatically adjust the actual length of the telescopic rod 53, after the lower upright 51 is turned in place, the pin 533 is inserted into the corresponding insertion holes of the sleeve 531 and the insert rod 532 to lock the telescopic rod 53, and thus after the lifting rope 23 is penetrated in the guide assembly, the high-level bracket 5 can mount the heavy hammer 22 to realize the lifting of the heavy hammer 22.
When the equipment is required to be transferred after the construction of the carrier piles in the construction area is completed, firstly, the heavy hammer 22 on the lifting rope 23 is removed, the locking of the pins 533 to the sleeve 531 and the inserted link 532 is released, the upper upright 52 and the lower upright 51 are overturned to be horizontal, then the locking of the locking assembly to the upper upright 52 is released, the hinge lugs 535 on the sleeve 531 are removed from the hinge bases 536 of the upper upright 52 and then are mounted on the hinge bases 536 of the lower upright 51, and at the moment, the upper upright 52 can be overturned on the lower upright 51 to be attached to the lower upright 51, so that the storage of the upper upright 52 and the lower upright 51 can be realized, and the low-cost transportation during the transfer of the construction equipment can be realized.

In the concrete setting, considering that when the filler is rammed, the heavy hammer 22 can give acceleration to the lifting rope 23 after freely falling, so that after the heavy hammer 22 bottoms out, the lifting rope 23 still can continue to move to cause the phenomenon that the lifting rope 23 is thrown off, the guide component is required to have a guide effect, and a certain limiting effect is also required to be achieved on the lifting rope 23; therefore, referring to fig. 1 and 7, the guide assembly is configured to include a guide frame 541 mounted at a free end of the upper upright 52, and when the upper upright 52 is in a vertical state, the guide frame 541 is in a triangle shape, two pulleys 542 are rotatably disposed on the guide frame 541 and two corners of the guide frame 541 are arranged separately, a groove on an outer circumferential side of an arc surface of the pulleys 542 is adapted to a size of the lifting rope 23, the guide frame 541 is disposed on a side, away from the two pulleys 542, of the guide frame 541, with an anti-drop roller 543 for abutting the lifting rope 23 in the groove of the pulleys 542, and the anti-drop roller 543 is rotatably disposed on the guide frame 541.
