Description

Automatic bolt fastening and dismounting system for tubular pile die

Technical Field

The invention mainly relates to the field of pipe pile production and manufacturing, in particular to an automatic bolt fastening and dismounting system for a pipe pile die.

Background

In the current construction operation, a large amount of pipe piles are required. The tubular pile mould is used in the production and manufacture of the tubular pile. The tubular pile die comprises an upper die cover and a lower die cover, the upper die cover and the lower die cover are fastened by a plurality of studs after being covered together, and the tubular pile die can be recycled.

Therefore, in the production and manufacture of the pipe pile, the pipe pile die is used for multiple different operations, such as fastening the bolts on the pipe pile die to facilitate the subsequent concrete centrifugation after die assembly, such as conveying the centrifugally molded centrifugal square pile with the dies to perform maintenance operation, such as disassembling the bolts on the pipe pile die before demolding to facilitate demolding and transferring the pipe pile finished product, and such as subsequent cleaning operation on the pipe pile die. In the fastening operation and the dismounting operation of the bolt on the tubular pile die, the following technical problems exist:

1. Many of the current pipe pile moulds are manually operated, but the pipe pile moulds are long (tens of meters or even tens of meters) and the bolts are large in quantity, so that the working efficiency is low, the labor cost is high, the production risk is high, and the automation level is low.

2. The current work efficiency is low. Many all need wait for the tubular pile mould to stop earlier and carry the back, fasten or dismantle the operation to the bolt earlier, carry out tubular pile mould after accomplishing and carry out tubular pile mould again, greatly reduced work efficiency.

3. At present, devices such as a gun machine and the like are partially used for fastening and disassembling bolts, and the gun machine is large in noise, causes noise pollution and is not beneficial to production operation. The screw bolt is not tightly twisted due to insufficient torsion, so that the later-stage die assembly centrifugal operation is influenced, the screw bolt cannot be loosened due to insufficient torsion caused by the expansion of the installed screw bolt at the later stage, further the later-stage demolding operation is influenced, and the phenomenon of 'jump' is formed due to the fact that the screw bolt is too tightly twisted but the rotary drill bit is not timely stopped, so that the rotary drill bit is damaged, and the screw bolt head is damaged. Fourthly, the bolt can be clamped in the rotary drill bit after being loosened, and the next operation can be affected if the bolt is not taken out in time, and the manual taking out can increase the labor cost, reduce the operation efficiency and possibly generate safety production accidents.

5. Current automation levels are low. To increase the level of automation, a batch of automation equipment is required to complete the various tasks described above. However, in the automatic operation, the tubular pile die in the transmission needs to be positioned first, and other tools (such as a bolt fastening device, a bolt dismounting device and the like) can perform subsequent accurate automatic operation on the tubular pile die in the transmission only if the accurate positioning is ensured, and in the positioning process, the tubular pile die is ensured not to stop the transmission, so that the work efficiency is improved greatly, the labor cost is reduced greatly, and the production risk is reduced greatly. And the tubular pile die is long in length and heavy in weight, and horizontal deviation is unavoidable in transportation, so that the tubular pile die is inconvenient to move in positioning and gesture adjustment, and the positioning equipment can only adapt to the tubular pile die and simultaneously position and move the positioning mechanism in front, back, left and right directions. Therefore, it is necessary to invent a device capable of automatically positioning the pipe pile die in the process of transmission.

5. At present, many devices have poor integration level and large occupied area, and have high requirements on the service area of factories.

Detailed Description

The invention will be described in further detail with reference to the drawings and the specific examples.

As shown in fig. 1 to 21, the invention provides an automatic bolt fastening and dismounting system for a pipe pile die, which comprises a cabinet 1, wherein the cabinet 1 is provided with a channel for conveying the pipe pile die 9, a starting sensor (shown as M in the figure) is further arranged on the cabinet 1, a movable positioning frame 2 capable of moving along the conveying direction is arranged above the channel on the cabinet 1, a vertical positioning device 3, a horizontal positioning device 4 and a plurality of fastening and dismounting devices 5 are arranged on the positioning frame 2, the vertical positioning device 3 is used for vertically positioning the pipe pile die 9 below and then sending out a vertical positioning signal, and synchronously conveying the movable positioning frame 2 along with the pipe pile die 9, and the horizontal positioning device 4 comprises two vertical horizontal positioning clamping frames 42 which are oppositely arranged left and right and is used for clamping the pipe pile die 9 according to the vertical positioning signal to form horizontal positioning and then sending out a horizontal positioning signal, so that the plurality of fastening and dismounting devices 5 fasten and dismount a plurality of bolts on the pipe pile die 9. In this embodiment, slide rail assemblies are disposed on two sides of the movable positioning frame 2, so that the movable positioning frame 2 can translate along the transmission direction of the pipe pile die 9 on the cabinet 1, and meanwhile, a translation cylinder (shown as K in the figure) is disposed on one side of the movable positioning frame 2, so that the movable positioning frame 2 can be actively driven to translate. The specific implementation principle is as follows:

When the pipe pile die 9 is conveyed into the cabinet 1 by the flatcar, the vertical positioning device 3 is sensed and started by the starting sensor, so that the vertical positioning device 3 falls from above to vertically position the pipe pile die 9 in the conveying process below and send out a vertical positioning signal. Meanwhile, as the movable positioning frame 2 can translate on the cabinet 1, the pipe pile die 9 in transmission can drive the movable positioning frame 2 to translate together forward through the connected vertical positioning device 3, namely, drive the horizontal positioning device 4 on the movable positioning frame 2 and the fastening and dismounting devices 5 to translate together. In this process, the horizontal positioning device 4 receiving the vertical positioning signal is started, and the two vertical horizontal positioning clamping frames 42 arranged opposite to each other on the left and right start to clamp relatively according to the vertical positioning signal, clamp the tubular pile die 9 gradually to form horizontal positioning, and send out the horizontal positioning signal. At this time, the pipe pile dies 9 in the transfer are vertically positioned by the upper vertical positioning device 3 and horizontally positioned by the horizontal positioning clamping frames 42 clamped at both sides, respectively. At this time, the plurality of fastening/detaching devices 5 having received the horizontal positioning signal start the operation, and perform the accurate fastening or detaching operation for the plurality of bolts on the lower pipe pile die 9.

When the bolt fastening operation or the dismounting operation is completed, the fastening dismounting device 5 is lifted and retreated to the original position, the two vertical horizontal positioning clamping frames 42 are horizontally moved and retreated to the original position, clamping is not formed on the tubular pile mold 9 any more, and the vertical positioning device 3 is lifted and retreated to the original position. At this time, the translation cylinder drives the movable positioning frame 2 to translate back to the original position. Then the vertical positioning device 3 falls down from above again to vertically position the pipe pile die 9 in the transmission below and send out a vertical positioning signal, the horizontal positioning device 4 forms horizontal positioning again and sends out a horizontal positioning signal, and the plurality of fastening and dismounting devices 5 start operation again, so that the circulation is completed.

Through the special scientific design, the method has the following technical advantages:

As shown in fig. 4 to 10, further, in the preferred embodiment, the vertical positioning device 3 includes a telescopic mechanism 31 and a positioning rod 32, the positioning rod 32 is connected with the driving end of the telescopic mechanism 31, the positioning rod 32 is provided with a positioning hook 33 protruding towards the pipe pile die 9, the positioning hook 33 is slidably arranged on the positioning rod 32 along the transmission direction of the pipe pile die 9, the positioning rod 32 is further provided with a vertical sensing component 34 near the positioning hook 33 for sending out a sensing signal when the positioning hook 33 slides, and the telescopic mechanism 31 stretches out and drives the positioning rod 32 to move towards the pipe pile die 9 in transmission during vertical positioning operation, and is used for enabling the positioning hook 33 to be driven to slide by the pipe pile die 9 after hooking a running wheel 91 on the pipe pile die 9, so that the vertical sensing component 34 sends out a sensing signal. The specific implementation principle is as follows:

since the pipe pile die 9 is long, and is provided with a plurality of running wheels 91 (existing structure) arranged at equal intervals. Each running wheel 91 can be used as a positioning reference point. In operation, the telescopic mechanism 31 drives the positioning rod 32 downwards, at this time, the pipe pile die 9 is transported to the lower part of the positioning rod 32, and the first protruding running wheel 91 on the pipe pile die 9 contacts the positioning hook 33 and drives the positioning hook 33 to slide forward. Once the positioning hooks 33 slide, the vertical sensing assembly 34 emits a sensing signal. Once the operation is completed, the telescopic mechanism 31 drives the positioning rod 32 to ascend so as to be separated from the first running wheel 91. In the next operation, the telescopic mechanism 31 drives the positioning rod 32 to descend again, and as the pipe pile die 9 is continuously conveyed, the second conveyed running wheel 91 continuously hooks the positioning hook 33 to slide forwards, and then the vertical sensing assembly 34 sends out a sensing signal again to perform the second operation. In this way, the cycle is completed. Through the special scientific design, the method has the following technical advantages:

According to the automatic bolt fastening and dismounting system for the tubular pile die, provided by the invention, the tubular pile die 9 can be automatically positioned by the running wheel 91 flexibly through the telescopic mechanism 31, the positioning rod 32, the positioning hook 33 and the vertical induction component 34 which are matched, so that an excellent vertical positioning signal is provided, the tubular pile die 9 can be kept in a transmission state in the operation process, automatic operation of automatic operation equipment is facilitated, the working efficiency is greatly improved, and the labor cost is greatly reduced.

The hollow structure of the positioning rod 32 facilitates the linear movement of the rod moving part 331, and the whole structure is simple and compact, thereby facilitating the installation and manufacture. The first elastic member 321 has two special functions, namely, when the positioning hook 33 is driven by the pipe pile die 9 to slide forward, the front end of the moving part 331 gradually presses the first elastic member 321, so that the moving part 331, namely, the positioning hook 33, is buffered, the moving part 331 cannot strike the end of the positioning rod 32, and the horizontal positioning device 4 and the fastening and dismounting devices 5 can be conveniently and quickly automated in the process. And secondly, once the operation is finished, the telescopic mechanism 31 drives the positioning rod 32 to ascend so as to separate from the first running wheel 91, and the separated moving part 331 slides backwards under the elastic recovery action of the first elastic piece 321 so as to reset to the vertical sensing assembly 34, so that the next positioning sensing operation is facilitated. Of course, in other embodiments, the first elastic member 321 may not be disposed at the front end of the moving portion 331, but may be disposed at the rear end of the moving portion 331, for pulling the moving portion 331 sliding forward, and pulling the moving portion 331 back for resetting after the operation is finished, which is all the simple position transformation shall fall within the scope of the present invention.

The specific implementation principle is as follows:

Since the pipe pile die 9 is long, and a plurality of running wheels 91 are provided at equal intervals. Each running wheel 91 can be used as a positioning reference point. In operation, as shown in the figure, when the horizontal positioning device 4 receives the vertical positioning signal, the driving assembly 45 drives the two horizontal positioning clamping frames 42 to gradually approach, and finally the left and right positioning guide sleeves 43 guide and clamp the running wheel 91 on the pipe pile die 9 into the left and right positioning guide sleeves 43 to form positioning. After the operation is finished, the driving assembly 45 drives the two horizontal positioning clamping frames 42 to be gradually separated, so that the left positioning guide sleeve 43 and the right positioning guide sleeve 43 are not clamped and positioned on the running wheel 91, and the circulation is realized. In the positioning process, it is assumed that the pipe pile die 9 is not just at the center point between the two horizontal positioning jigs 42, and it is assumed that the pipe pile die 9 is closer to the right-hand horizontal positioning jigs 42. At this time, when the driving assembly 45 drives the two horizontal positioning clamping frames 42 to gradually approach each other, and the positioning guide sleeve 43 on the horizontal positioning clamping frame 42 on the right side clamps the right end of the running wheel 91, the horizontal positioning clamping frame 42 on the left side will continue to move until the left end of the running wheel 91 is clamped, so as to form horizontal centering positioning, that is, the problem of positioning in the direction of arrow C-D in the figure is solved.

Through the special scientific design, the pipe pile die 9 has the technical advantages that the pipe pile die 9 can be flexibly arranged on the left and right working surfaces of the pipe pile die 9 by arranging the matched driving assembly 45, the horizontal positioning clamping frame 42 and the positioning guide sleeve 43, and then the running wheel 91 is utilized to automatically position the pipe pile die 9, so that automatic operation equipment is convenient for automatic operation, the working efficiency is greatly improved, and the labor cost is greatly reduced.

In this embodiment, two second links 423 are disposed obliquely on each horizontal positioning clamping frame 42. Through repeated experiments, in the clamping process, in order to ensure that the positioning accuracy is ensured, the driving assembly 45 can provide extremely strong clamping force for the two horizontal positioning clamping frames 42, so that the running wheel 91 can generate extremely strong reaction force for the two horizontal positioning clamping frames 42 during operation, if the special structures such as the third sliding rod 421, the sliding sleeve 422 and the obliquely arranged second connecting rod 423 are not arranged, the reaction force can jack up the horizontal positioning clamping frames 42 towards the upward direction in the figure, and the upper end of the horizontal positioning clamping frames 42 is arranged on the frame 41, the horizontal positioning clamping frames 42 can only horizontally move transversely and cannot move up and down, so that the upward force can push up the horizontal positioning clamping frames 42 or the sliding rail assembly or the frame 41, the service life of equipment is greatly reduced, and the positioning accuracy is also reduced. In order to solve the technical problem, under the demonstration of multiple experiments, the invention further provides a special structure such as the third slide bar 421, the slide sleeve 422 and the second connecting rod 423 which are obliquely arranged, and the special structure can well conflict with the reaction force of the running wheel 91 to the upward jacking of the horizontal positioning clamping frame 42, thereby well prolonging the service life of the equipment and ensuring the development of high-precision positioning.

Further, in the preferred embodiment, the drive assembly 45 includes two drive cylinders 451 disposed in an inclined arrangement, each drive cylinder 451 being mounted with respect to a respective one of the horizontal positioning and clamping frames 42, the lower end of the drive cylinder 451 being hinged to the horizontal positioning and clamping frame 42 and the upper end being hinged to the frame 41.

Since the pile mould 9 is long and is transported continuously, this may cause the running wheel 91 on the pile mould 9 to be not exactly located at the centre of the positioning guide 43, i.e. there is a problem of positioning the position in the direction of arrow a-B in the figure. To solve this problem, the present invention further provides two guide plates 432 for forming a bell-mouth shaped guide slot, and the positioning guide sleeve 43 can gradually guide when approaching the running wheel 91 and finally guide the running wheel 91 into the positioning slot 431 to be clamped. During this guiding movement, a translational sliding movement takes place on the frame 41. Finally, the running wheel 91 is clamped and positioned in the positioning groove 431, so that an extremely accurate positioning effect is formed, namely, the problem of positioning the position in the direction of the arrow C-D is solved, the problem of positioning the position in the direction of the arrow A-B is also solved, and the positioning accuracy is extremely high.

The specific implementation principle is as follows:

Taking the bolt disassembling operation as an example, when the fastening and disassembling device 5 receives the horizontal positioning signal, the rotation driving mechanism 52 drives the transmission spline rod 541 to rotate forward, so that the transmission spline housing 542 on the transmission spline rod 541 also rotates, and further, the sleeve assembly 55 on the bottom end of the transmission spline housing 542 also rotates. At the same time, the lifting driving mechanism 53 drives the impact hammer 56 to move downwards, so that the impact hammer 56 can squeeze the third elastic piece 57 below and the third elastic piece 57 can squeeze the bearing assembly 545 below, at the moment, the bearing assembly 545 can drive the rotating transmission spline housing 542 to move downwards, finally, the sleeve assembly 55 on the bottom end of the transmission spline housing 542 can rotate and descend to approach the bolt of the pipe pile die 9 below, and finally, the sleeve assembly 55 can actively find out the bolt head and finally firmly sleeve the bolt head through rotation and descent. At the same time, the lifting drive mechanism 53 will continue to drive downwards, so that the sleeve assembly 55 not only nests the bolt head, but will also exert a downward pressure on the bolt head, i.e. the sleeve assembly 55 will "nest" on the bolts of the pile mould 9. This pressure allows the sleeve assembly 55 to impart excellent rotational torque to the bolt, thereby allowing the firm bolt to be easily removed from the knob. During the disassembly process, the bolts tend to rise gradually, but due to the special arrangement of the third elastic members 57, the bolts can also be pressed upward normally and finally exit the screw holes.

The bolt fastening operation is similar to that of pre-installing the bolt in the screw hole of the pipe pile die 9 (not fully fastening), then conveying the pipe pile die 9 to the lower part of the invention, when the fastening and dismounting device 5 receives a horizontal positioning signal, the rotary driving mechanism 52 drives the transmission spline rod 541 to reversely rotate, the lifting driving mechanism 53 drives the impact hammer 56 to downwards move, and finally, the sleeve assembly 55 is enabled to transmit excellent rotary torsion on the bolt of the pipe pile die 9 in a sleeving manner, and then the bolt is tightly screwed on the pipe pile die 9.

the fastening and dismounting device 5 is high in automation level, can realize bolt fastening operation and bolt dismounting operation through forward and reverse rotation, greatly improves working efficiency, and greatly reduces labor cost and production risk.

The fastening and dismounting device 5 of the invention ensures that the sleeve assembly 55 actively finds out the bolt head through rotation and descending and finally firmly sleeves on the bolt through the mutual matching of the components such as the rotary driving mechanism 52, the lifting driving mechanism 53, the transmission spline rod 541, the transmission spline housing 542, the impact hammer 56, the third elastic piece 57, the bearing assembly 545, the sleeve assembly 55 and the like, so that the sleeve assembly 55 can transmit excellent rotation torsion to the bolt. This allows the rotary drive mechanism 52 to operate without the use of a powerful, noiseless drive similar to a wind cannon machine, greatly reducing noise pollution. Meanwhile, the device has excellent tightening and loosening effects, and is extremely convenient for the normal development of later-stage die assembly centrifugal operation and demolding operation.

Thirdly, in the fastening and dismounting device 5 of the invention, as the sleeve assembly 55 is firmly sleeved on the bolt and the downward pressure is always applied to the bolt head while the knob is turned, the phenomenon of machine jump is avoided, the sleeve assembly 55 or the bolt is not damaged, and the service life of equipment is prolonged.

Further, in the preferred embodiment, an impact damper 58 is further fixed on the driving spline housing 542 above the impact hammer 56, and when the lifting driving mechanism 53 stops driving the impact hammer 56 to move downward after the bolt tightening and disassembling operation is finished, the impact hammer 56 is quickly retracted upward and impacts the impact damper 58 under the elastic restoring action of the third elastic member 57, so that the bolts in the sleeve assembly 55 are shaken off. Since the third elastic member 57 is compressed seriously during operation, after the operation is finished, once the lifting driving mechanism 53 stops driving the impact hammer 56 to move downwards, that is, the impact hammer 56 can not apply force to the third elastic member 57, the third elastic member 57 can lift the impact hammer 56 downwards rapidly under the elastic restoring action, and the impact hammer 56 impacts the impact baffle plate 58 above rapidly and then vibrates, so that the bolt possibly trapped in the sleeve assembly 55 is vibrated down. That is, the impact baffle plate 58 is utilized to produce impact fit with the automatic-retreating impact hammer 56, so that the problem that bolts are clamped in the sleeve assembly 55 is well solved, the sleeve assembly 55 can be conveniently and rapidly unfolded for next batch of operation, manual intervention is not needed in automatic detachment, labor cost is greatly reduced, operation efficiency is improved, and potential safety hazards of safety production possibly occurring are eliminated.

By arranging the top mounting plate 51, the rotary driving mechanism 52 and the lifting driving mechanism 53 are convenient to mount, and the arrangement of the two cylinders not only can provide excellent pressing driving force for the impact hammer 56 so as to realize excellent tightening and loosening operation, but also ensures the stability of the impact hammer 56 during retraction and impact.

Further, in the preferred embodiment, a retractable dust tube 546 is fitted over the drive spline housing 542 between the impact shield 58 and the drive end of the rotary drive mechanism 52.
