Description
Technical Field
The invention belongs to the technical field of methods or machines specially suitable for manufacturing tubular products in operation and transportation, and particularly relates to an unpowered self-adaptive tubular pile die assembling and disassembling method.
Background
At present, the process for manufacturing the concrete pipe pile comprises the following steps in sequence: drawing wires, braiding cages, distributing concrete materials, closing dies, tensioning, centrifugally forming, protecting steam and demolding. The process of die assembly and die release requires that bolts on the tubular pile die be fully screwed and unscrewed. The tubular pile die is linear, and can be seen in figure 1, and is formed by buckling an upper die and a lower die with semicircular sections, connecting edges are arranged on the buckling surfaces of the upper die and the lower die along the radial outer edge, and the connecting edges of the upper die and the lower die are bolted through a plurality of bolts. However, the pipe pile die 100 has a long length, and the number of bolting units 101 equally spaced along the length thereof is correspondingly large, and symmetrically arranged on both sides.
The traditional operation mode in the industry is that a pipe die moves forward at the speed of about 200mm/s, one worker stands on each side, when the corresponding bolt moves to a worker standing station, the worker holds a wind cannon to screw or detach the bolt, and the operation is repeated. There are two prominent problems with the conventional approach: 1. even at the cost of reducing the advancing speed of the pipe die (reducing the production efficiency), the problem of overlarge labor intensity still exists; 2. the tightening process needs to ensure a certain torque application period, and a worker who is tired of the operation has difficulty in ensuring the torque application period, resulting in poor tightening effect. If the quick-release turnover bolts (refer to CN 206464802U) are arranged on the pipe pile die, an auxiliary worker is usually required to specially perform the operation of turnover bolts, and the labor cost is further increased.
To solve the above problems, a series of automatic apparatuses and systems for tightening/removing the pipe pile die bolts, such as the apparatuses disclosed in CN107932046A, CN107803926A, CN207464881U of the university of Hubei industries, the apparatuses disclosed in the constant force boiler CN206464802U, CN109175983A, CN210731587U, the apparatuses disclosed in Guangzhou Deya CN106738305a, etc., the apparatuses disclosed in Zhou Zhaodi CN211762309U, etc., and the apparatuses disclosed in CN108638321A, CN211616075U, have been developed, but there are some problems, and the two problems are mainly analyzed.
In the research direction, the forced research and development equipment is suitable for the existing tubular pile mould with poor dimensional accuracy, and some tubular pile moulds are inverted at last, so that the equipment cost is too high and the equipment is not practical-! For example, the problem that the bolts are not equidistant and the actual spacing precision of the bolts is low, so that the wind cannon accurately sleeves the bolts and has deviation is solved simply and well by the wind cannon with flexibility as disclosed in CN105583612A, CN207464644U, and the problem that the turnover type bolts are required to be turned over and disassembled quickly is solved thoroughly by the pipe pile die screws as disclosed in CN 101758554A. It is unnecessary to add series of complex functions such as multidirectional detection, multidirectional driving, righting and positioning of a turnover bolt and driving and positioning of a plurality of air cannons respectively on research and development equipment. The tubular pile mould is also a consumable product, and after the tubular pile mould with poor dimensional accuracy used at the initial stage is abandoned, the tubular pile mould manufactured according to the tubular pile mould standard specification can lead many functions of the complex equipment to be dummy, and for tubular pile manufacturers, the novel tubular pile mould and corresponding equipment are obviously more practical than the equipment with complex structure and functions for seeking ultra-high price. The equipment with complex functions and structures is higher in failure rate and maintenance cost, and often influences production plans and progress, and is common knowledge.
There are mainly three forms from the concrete structural form. The first is that the pipe die moves forward under the traction of the traction mechanism, a plurality of air cannons arranged in parallel with the pipe die follow the pipe die under the drive mechanism, and descend to screw or disassemble, after the screwing and the disassembling of a group of bolts corresponding to the number of the air cannons are completed, the pipe die is quickly lifted and returned to an initial position, and the following screwing and the disassembling of the next group of bolts are prepared; the form needs to be returned, the torque application duration is ensured, the advancing speed of the pipe die is easy to limit, the production efficiency is influenced, and because the advancing speed of the pipe die is possibly non-uniform, deviation can exist when the air cannon is aligned along with the pipe die and is aligned again after the pipe die is returned, the pipe die and equipment are damaged, and for this purpose, the form of equipment with an outer frame provided with the air cannon is driven by a follow-up unit disclosed by CN209954955U in Guangzhou Deya, the problem of the air cannon following alignment can be solved to a certain extent, but after the screwing and the disassembling of a group of bolts are completed, the air cannon still needs to be lifted and returned to the initial position. The second is that the pipe die is stopped after moving forwards for a designated length, the tightening device descends and performs tightening and loosening, after the tightening and loosening of one group of bolts are completed, the pipe die is lifted, the pipe die is stopped after moving forwards for a designated length, and the tightening device descends and performs tightening and loosening of the next group of bolts; the advancing movement of the lower pipe die in the form needs to be stopped at intervals, and the production efficiency is affected. Thirdly, the pipe die is static, long guide rails for the tightening devices to move are paved on two sides of the pipe die, the tightening devices move on the guide rails, after the tightening and the disassembling of one group of bolts are completed, the pipe die is lifted and moves to the position of the next group of bolts along the length direction of the pipe die, and then the tightening and the disassembling are performed. The form needs to lay longer guide rails on two sides of the pipe die, occupies a large area, and has high reconstruction cost on the existing production site.
Aiming at the current situation, the patent application provides a brand new automatic bolt tightening/disassembling scheme aiming at the tubular pile die (such as figure 1, which is used in a large amount at present) with better quality consistency (equal spacing of bolts) and provided with rebound bolts, which is manufactured after standardization.

Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the drawings.
Referring to fig. 2-4, the method for assembling and disassembling an unpowered self-adaptive tubular pile die in the embodiment includes a tubular pile die capable of moving along a length direction thereof under the action of a traction unit, wherein a plurality of bolting units are arranged on the tubular pile die along the length direction at intervals, the method adopts a device with an annular circulating mechanism 1 to assemble and disassemble the bolting units, the annular circulating mechanism 1 includes a flexible chain ring 3, and the flexible chain ring 3 is connected on a base frame body 2 in a surrounding manner and can rotate around the base frame body 2 in a circulating manner under the action of driving force; at least one section of the flexible chain ring 3 always keeps parallel to the length direction of the tubular pile die when the flexible chain ring rotates around the base frame body 2, and the section is formed into a current working section 31; a plurality of independently lifting assembly and disassembly units 4 are arranged on the flexible chain ring 3 at intervals along the length direction and are used for assembling and disassembling the bolting units; the linear distance between the adjacent assembling and disassembling units 4 in the length direction of the flexible chain ring 3 corresponds to the distance between the adjacent bolting units in the length direction of the tubular pile mould;
The method also comprises the following steps:
1) The tubular pile die keeps moving;
2) The assembly and disassembly units 4 on the current working section 31 of the flexible chain ring 3 descend and are in operative connection with the corresponding bolting units;
3) The mounting and dismounting unit 4 applies work to the bolting unit, and meanwhile, the moving tubular pile die is connected with the flexible chain link 3 by virtue of the bolting unit and the mounting and dismounting unit 4 to provide the driving force for circularly rotating around the base frame body 2 so as to drive the flexible chain link 3 to circularly rotate around the base frame body 2;
4) The next assembly and disassembly unit 4 descends and is in operative connection with the corresponding bolting unit after moving to the current working section 31 along with the flexible chain ring 3;
5) The last assembly and disassembly unit 4 rises and is disconnected with the action connection of the corresponding bolting unit;
6) Repeating 3) -5) until the assembly and disassembly of the bolting unit on the pipe pile die are completed.
According to the assembly and disassembly method of the embodiment, the flexible chain ring 3 can continuously obtain the driving force for circularly rotating around the base frame body 2 from the moving tubular pile die through the action connection of the assembly and disassembly units 4 and the corresponding bolting units, and the circulation can be completed, so that the tightening or the disassembly of all the bolting units arranged on the tubular pile die at intervals along the length direction can be realized, and it can be understood that the tightening and the disassembly are generally in an alternative mode during the same operation, and the working direction of the assembly and disassembly units 4 can be changed through the corresponding selection of the controller of the equipment.
In the method, the flexible chain ring 3 obtains power from the linear motion of the tubular pile die from the first assembling and disassembling unit 4 which is used for connecting the bolting unit, so that the flexible chain ring 3 is driven to do unpowered synchronous following motion along with the tubular pile die, of course, the unpowered driving unit which is specially used for driving the flexible chain ring 3 to synchronously follow motion along with the tubular pile die is not arranged on the device, and compared with the existing automatic device, the method has the distinguishing point and advantages that the flexible chain ring 3 is provided with a plurality of assembling and disassembling units 4, and each assembling and disassembling unit 4 orderly performs descending connection-screwing-ascending disconnection processes in the current working section 31 in the synchronous following motion process, thereby completing the whole screwing operation, really realizing the functions of no stagnation of the tubular pile die, no return idle stroke of the assembling and disassembling units 4 and self-adapting the moving speed of the tubular pile die, effectively improving the production efficiency and completely not limiting the moving speed of the tubular pile die; in addition, even if the moving speed of the pipe pile die is uneven, the problem that the assembling and disassembling unit 4 is difficult to align with the bolting unit to damage equipment and the pipe pile die in the descending process is avoided, the practicability is extremely strong, and thus, the unpowered self-adaptive pipe pile die assembling and disassembling method is realized! It will be appreciated that the process of orderly performing the descending connection-tightening-ascending disconnection of each assembly and disassembly unit 4 at the current working section 31 can be achieved by sensing in place by a sensor on the equipment (base frame body 2) and combining with the control of the electronic control part of the equipment.
It can be seen that the method can also effectively ensure the duration of the torque applied by the assembling and disassembling unit 4 to the bolting unit, and if the duration of the torque applied by the assembling and disassembling unit 4 to the bolting unit is required to be prolonged, the length of the current working section 31 of the flexible chain ring 3 is properly prolonged, and the screwing/disassembling bolt quality of the tubular pile die can be well ensured. As can be seen from the process of cyclic working, the number of the independently liftable units 4 is at least three, and because the linear distance between two points (the current working section 31) is shortest, the length of the other sections (outside the current working section 31) on the flexible chain ring 3 is necessarily larger than that of the current working section 31, at least three independently liftable units 4 are arranged on the flexible chain ring 3 along the length direction at intervals, so that the unpowered self-adaptive cyclic mounting and dismounting can be effectively performed, and the length of the current working section 31 is larger than the linear distance between any two adjacent mounting and dismounting units 4 along the length direction of the flexible chain ring 3. In the device of this embodiment, seven detachable units 4 capable of being lifted independently are provided, the length of the current working section 31 allows three detachable units 4 to be located on the current working section 31 at the same time, when the front detachable unit 4 ascends and disengages, two detachable units 4 descend and are in operative connection with corresponding bolting units, so that the reliability of the tubular pile die for driving the flexible chain ring 3 to rotate circularly can be improved, damage caused by driving force transmission only by a single pair of detachable units 4 and bolting units can be avoided, the duration of torque application of the detachable units 4 to the bolting units can be effectively ensured, and the device width can not be too large.
The device has the advantages of relatively simple structure, small volume, small occupied production field space, small modification to the existing production line and practicability.
Wherein, each bolting unit is equidistantly spaced in the length direction of the tubular pile die, and correspondingly, the linear distance between adjacent assembling and disassembling units 4 in the length direction of the flexible chain ring 3 is equidistant.
Therefore, the design and manufacture of the device can be more simply matched with the pipe pile die, and the use reliability is ensured. Of course, it is not excluded that the bolting units in the length direction of the pile mould are grouped according to the total length of the flexible links 3, and that the spacing of the bolting units on each group corresponds to the spacing of the mounting and dismounting units 4, in which case the method (apparatus) can be used even if the spacing of the bolting units (mounting and dismounting units 4) is non-equidistant, which is why the foregoing does not require that the mounting and dismounting units 4 must be equally spaced.
Wherein, the flexible chain ring 3 is also provided with a baffle unit 5 which can be lifted independently, and the lifting direction corresponds to the mounting and dismounting unit 4; the baffle units 5 are positioned at the middle positions of any two adjacent assembling and disassembling units 4 in the length direction of the flexible chain ring 3; in the length direction of the tubular pile mould, the distance from the end face of the tubular pile mould to the adjacent bolting unit is half of the distance between the adjacent bolting units (in actual cases, two data are distributed to be 125.5mm and 250 mm);
The assembly and disassembly method further comprises the following initial linkage process:
Before the assembly and disassembly units 4 on the flexible chain ring 3 are connected with the corresponding bolting units on the pipe pile die for the first time, the baffle plate units 5 move to the designed initial position on the current working section 31 along with the flexible chain ring 3 and descend for waiting;
The tubular pile die moves towards the baffle unit 5, and the end face of the tubular pile die abuts against the baffle unit 5 to drive the flexible chain ring 3 to circularly rotate;
The assembly and disassembly units 4 adjacent to the baffle units 5 descend along with the flexible chain ring 3 to the current working section 31 and are in operative connection with the corresponding bolting units;
the baffle unit 5 rises away from the pipe pile die.
Therefore, besides the first action of the assembling and disassembling unit 4 and the connecting unit is controlled and completed by the in-place sensing of the sensor, the baffle unit 5 can be used for more accurately and reliably ensuring the completion of the first action connection of the assembling and disassembling unit 4 and the bolting unit and ensuring the realization of the subsequent process. It will be appreciated that after the baffle unit 5 used as the initial linkage is lifted away from the pipe pile die, the baffle unit 5 need not and cannot be lowered any more before all the bolting units of the section of pipe pile die are completely assembled and disassembled, so as to avoid collision with the pipe pile die. After the end face of the pipe pile die abuts against the baffle plate unit 5 and drives the flexible chain ring 3 to circularly rotate, in order to ensure that the adjacent assembly and disassembly units 4 have enough time to descend and are in operative connection with the corresponding bolting units, the initial design position is located at one end of the current working section 31 of the flexible chain ring 3 facing the pipe pile die.
Wherein the base frame body 2 is provided with an initial position return unit 6 and acts on the flexible link 3 for moving the damper unit 5 with the flexible link 3 to a design initial position on the current working section 31 during said initial linkage.
Thus, the functional design is perfected, and the completion of the first-time action connection of the assembling and disassembling unit 4 and the connecting unit is further ensured when the pipe pile die is reused after being replaced each time.
The assembling and disassembling unit 4 comprises a wind cannon 41 (pneumatic wrench), the wind cannon 41 is connected to the flexible chain ring 3 through a lifting mechanism 42, and a sleeve 43 which is in operative connection with the lower end of the wind cannon 41 is sleeved on the head of a bolt in the bolting unit.

It will be appreciated that like the use of ratchet and pawl, when the telescopic rod is extended, the driving pawl 62 elastically yields and slides from the vertical link plate 32, and when the telescopic rod is retracted, the driving pawl 62 pulls the vertical link plate 32 forward; the return cylinder 61 stretches and draws work and drives the direction of the circular rotation of the flexible chain ring 3 through the driving pawl 62, the direction of the circular rotation of the flexible chain ring 3 driven by the tubular pile die is identical to the direction of the circular rotation of the flexible chain ring 3 driven by the tubular pile die in the process of assembling and disassembling the bolting unit, and when the flexible chain ring 3 is driven by the tubular pile die to rotate circularly, the driving pawl 62 only elastically gives way to enable the vertical chain plate 32 to slide through, so that the follow-up and assembling and disassembling processes of the flexible chain ring 3 are not influenced. Of course, regarding whether the initial position return unit 6 moves the baffle unit 5 to the design initial position along with the flexible chain ring 3, a sensor is further arranged on the equipment (the base frame body 2) to perform in-place sensing, and the sensor and the return cylinder 61 are also connected with an electric control part of the equipment, so that the control can be correspondingly realized.
