Detailed Description

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

As shown in fig. 1 to 4, the invention provides a bolt fastening and dismounting device for a tubular pile die, which comprises a rotary driving mechanism 2 and a lifting driving mechanism 3, wherein the driving end of the rotary driving mechanism 2 is fixedly connected with the top of a vertically arranged transmission spline rod 41, a transmission spline housing 42 in transmission fit is sleeved on the transmission spline rod 41, a sleeve assembly 5 is fixed at the bottom end of the transmission spline housing 42 and is used for performing forward and reverse rotation through the transmission of the transmission spline rod 41 and the transmission spline housing 42 under the forward and reverse driving of the rotary driving mechanism 2, a bearing assembly 45 is sleeved on the lower part of the transmission spline housing 42 above the sleeve assembly 5, an impact hammer 6 is movably sleeved in the middle part of the transmission spline housing 42, the driving end of the lifting driving mechanism 3 is connected with the impact hammer 6, an elastic piece 7 is further sleeved on the transmission spline housing 42 between the bearing assembly 45 and the impact hammer 6, during operation, the lifting driving mechanism 3 drives the impact hammer 6 to move downwards and extrude the elastic piece 7, so that the elastic piece 7 extrudes the bearing assembly 45 to drive the transmission spline sleeve 42 to move downwards, and the sleeve assembly 5 is continuously sleeved and pressed on the bolt of the tubular pile die 9 to perform bolt fastening and dismounting operation. In this embodiment, a flange plate assembly is provided at the driving end of the rotary driving mechanism 2 for forming a detachable fixed connection with the top of the transmission spline rod 41. The bolt fastening and dismounting device can be simultaneously arranged on a plurality of frames and is used for arranging a plurality of bolts on the corresponding tubular pile die 9, and the bolts can be simultaneously dismounted at one time. For example, the device can be installed on a die assembly bolt fastening machine and is used for performing bolt fastening operation on a die assembly pipe pile die, so that the concrete after die assembly is convenient to centrifuge; for example, the pipe pile mould can be arranged on a stripper, and the bolt is disassembled before the demoulding operation, so that the demoulding and the transfer of the pipe pile finished product are convenient; the pipe pile mould cleaning device can be arranged on a mould cleaning machine, so that the pipe pile mould can be cleaned conveniently after the bolt is detached. The specific implementation principle is as follows:

the following takes bolt removal operations as an example: fig. 1 is a schematic structural view of the bolt fastening and dismounting device of the present invention when it is not lowered, and when the tubular pile die 9 is conveyed to the lower part of the bolt fastening and dismounting device of the present invention, the rotary driving mechanism 2 drives the driving spline shaft 41 to rotate in the forward direction, so that the driving spline housing 42 on the driving spline shaft 41 also rotates, and further the sleeve assembly 5 on the bottom end of the driving spline housing 42 also rotates. Meanwhile, the lifting driving mechanism 3 drives the impact hammer 6 to move downwards, so that the impact hammer 6 presses the elastic piece 7 below, and the elastic piece 7 presses the bearing assembly 45 below; at this time, the bearing assembly 45 will drive the rotating driving spline housing 42 to move downward, and finally the sleeve assembly 5 on the bottom end of the driving spline housing 42 rotates and descends to approach the bolt of the tubular pile die 9 below, and finally the sleeve assembly 5 actively "looks" for the bolt head and finally firmly sleeves the bolt head by rotating and descending (as shown in fig. 2 and fig. 4). At the same time, the lifting driving mechanism 3 will continue to drive downwards, so that the sleeve component 5 not only nests the bolt head, but also applies downward pressure to the bolt head, that is, the sleeve component 5 is "pressed on" the bolt of the pipe pile mould 9. This pressure enables the sleeve assembly 5 to deliver an excellent torque to the bolt, thereby allowing the firm bolt to be easily unscrewed. In the process of disassembling, the bolt will tend to rise gradually, but because of the special arrangement of elastic component 7, make the bolt also can normally extrude to rise and finally withdraw from the screw up.

Bolt tightening operations are similar: the bolt is pre-installed in the screw hole of the tubular pile die 9 (not completely installed), then the tubular pile die 9 is conveyed to the lower part of the bolt fastening and dismounting device, the rotary driving mechanism 2 drives the transmission spline rod 41 to rotate reversely, the lifting driving mechanism 3 drives the impact hammer 6 to move downwards, finally the sleeve component 5 is pressed on the bolt of the tubular pile die 9 in a sleeved mode to transmit excellent rotary torque, and the bolt is tightly screwed on the tubular pile die 9.

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

Secondly, according to the bolt fastening and dismounting device for the tubular pile die, the sleeve component 5 actively looks for the bolt head through rotation and descending and finally firmly presses the bolt through the design that the parts such as the rotation driving mechanism 2, the lifting driving mechanism 3, the transmission spline rod 41, the transmission spline sleeve 42, the impact hammer 6, the elastic piece 7, the bearing component 45 and the sleeve component 5 are matched and supplemented with each other, so that the sleeve component 5 can transmit excellent rotation torque force to the bolt. This makes the rotary drive mechanism 2 able to operate without using a high-power, high-noise drive device similar to a wind cannon machine, greatly reducing noise pollution. Meanwhile, the excellent tightening and loosening effect greatly facilitates the normal development of the mold closing centrifugal operation and the mold releasing operation in the later period.

Thirdly, according to the bolt fastening and dismounting device for the tubular pile die, the sleeve component 5 is firmly pressed on the bolt in a sleeved mode, downward pressure is always applied to the bolt head while the knob is turned, so that the phenomenon of 'tripping' is avoided, the sleeve component 5 or the bolt is not damaged, and the service life of equipment is prolonged.

Because the pressure elastic component 7 has been compressed seriously during operation, after the operation, in case the lift actuating mechanism 3 stops driving the jump bit 6 and moves downwards, that is to say the jump bit 6 can not give the application of force to pressing the elastic component 7 again, press the elastic component 7 and can jack up the jump bit 6 down fast under the elastic recovery effect this moment to make the jump bit 6 strike the impact baffle 8 of top fast and then produce vibrations, and then will probably sink to establish the bolt of chucking in the sleeve subassembly 5 originally and be shaken and fall. The impact baffle 8 is used for being matched with the impact hammer 6 which returns automatically to impact, the problem that the bolt is clamped in the sleeve component 5 is solved well, the sleeve component 5 can conduct next batch of operation quickly, manual intervention is not needed when the bolt is automatically separated, the labor cost is greatly reduced, the operation efficiency is improved, and potential safety hazards which possibly occur are eliminated.
