This embodiment is provided with a guide groove 310 at the lower end of the wall plate 36. The guide groove 310 is provided to help a crane driver to complete the initial positioning of the pipe die by the fixture before grabbing the pipe die. The guide slot 310 can ensure that the jaws of the clamp combination are accurately and smoothly clamped, and if the guide slot 310 is not arranged downwards, a driver needs to lift again and then descend. The bright color mark on the guide groove 310 allows the driver to easily determine whether the guide groove 310 is accurately positioned.

The thickness of the first clamp 211 and the second clamp 311 in the embodiment is increased to 45mm from the original thickness of 20mm, so that the abrasion life of the clamp is greatly prolonged, and the normal service life can be prolonged by about 3 times. In addition, the first clamp 211 and the second clamp 311 both adopt No. 60 steel forgings (currently, Q235-B steel plates are adopted, and the strength and the wear resistance are to be improved), so that the strength and the wear resistance of the clamps are greatly improved, and the service life of the clamps is greatly prolonged.

Air compressor passes through trachea drive cylinder one and cylinder two, and this trachea diameter is changed into 12 ~ 14mm by 10mm with this embodiment for clamp action time shortens by a wide margin (closed to the open mode only needs about 0.5 second), has improved production efficiency greatly. Meanwhile, the signal feedback device is additionally arranged at the upper limit position and the lower limit position of the extension of the first air cylinder 21 and the second air cylinder 31, after the device is arranged, the opening and closing states of the clamp can be displayed by signal lamps, and an operator can directly visually observe the signal lamps (red indicates that the clamp is in the opening state, and green indicates that the clamp is in the closing state), so that the opening and closing states of the clamp can be confirmed, the condition that the clamp is opened (or closed) is avoided, and the clamp can be operated more safely and reliably.

As shown in fig. 3 or 11, in the present embodiment, the suspension beam 1 is made of a rectangular steel beam, and an inner cavity is formed inside the suspension beam 1, so that the cylinder one 21 and the cylinder two 31 can be arranged inside the inner cavity of the suspension beam 1, and the arrangement can protect the cylinder from being damaged by collision; the cylinder can be arranged on the outer side of the box body of the hanging beam 1, and the arrangement has the greatest advantage that the cylinder is very convenient to maintain and replace. The two forms can be selected according to the use condition of a client.

When a crane driver operates an electric control button to automatically clamp the pipe die in the air, the clamp has the following characteristics: firstly, the self-locking type is realized, and the jaw is tighter when the lifting weight is heavier; secondly, an indicator light is lighted up after the electric control button is pressed, so that a driver can clearly operate without errors; the air compressor 4 provides 0.75MPA working pressure for the first air cylinder 21 and the second air cylinder 31, if a driver mistakenly operates and presses the clamp opening button when the clamp holds a heavy object, the opening force generated by the working air pressure of the air cylinders to the clamp jaws is far smaller than the internal friction force between the clamp jaws and the heavy object, and the opening button is invalid; thrust generated under the working pressure of the cylinder is only used for completing opening and closing actions of the clamp and does not participate in load lifting and the self-locking characteristic of the clamp, so that the clamp can not be automatically opened and a pipe die falls off under serious conditions such as accidental power failure or sudden breakage of an air pipe and the like, and the safety performance is good; the self-locking characteristic of the clamp ensures that the pipe die can not fall off even when being impacted, and has good safety characteristic.

For the explanation above of the heavier sling, tighter jaw:

as shown in fig. 10, the principle of the stress of the band clamp 2 is analyzed as follows,

F=f，M=f·(h-H)；

since H is much greater than H, and therefore (H-H) is positive, the bending moment produced by M is inward, and the increase in F will also increase M. Therefore, the heavier the weight is, the greater the clamping force of the first two clamps 211 is; f force acts on the hanging beam 1, the clamp I211 is also fixed on the hanging beam 1, and therefore the active and passive transmission shafts 26 and the secondary and passive transmission shafts 27 on the clamp I211 are bearing shafts.

As shown in fig. 17, the principle of the force applied to the card jig 3 is analyzed as follows,

F=2f；m=f·h；

because the bending moments generated by F and h are inward, F is increased to increase F, and m = F · h is increased, the clamping force of the two clamp halves 311 is increased correspondingly as the weight is increased. F acts on the hanging beam 1, and the sliding of the second clamp 311 is also fixed on the hanging beam 1 two, so the pin 5 on the clamp 4 is also a bearing shaft.

As shown in fig. 18, it is the working flow of the clamp of the present invention:

the pipe die moves forwards after entering a pile removing area on the trolley, the position of a worker is fixed, the pipe die moves, the worker unloads the bolt on the pipe die, and when the pipe die completely enters the pile removing area, the bolt is completely unloaded. The crane is hung on the hanging beam 1 and moves to the upper part of the pipe die, a driver firstly positions the pipe die by the guide grooves 310 at all the directions of the clamping type clamp 3, after the clamp is in place, the clamping type clamp 3 is firstly used for clamping the upper die, then the holding type clamp 2 is put down, the crane starts to lift, and as the holding type clamp 2 is still away from the flange of the pipe die, the upper die is firstly lifted by lifting, and meanwhile, the upper die and the lower die are separated. At the moment, the jaw of the holding type clamp 2 is in contact with the lower die flange and enables the lower die to be lifted, the crane continues to lift, the crane starts to move, the crane descends until the pile removing area, the crane continues to descend after the lower pipe die is in contact with the ground, the jaw of the holding type clamp 2 is separated from the lower die flange and then descends to stop, and at the moment, the holding type clamp 2 is opened and continues to lift. And (3) moving the crane cart, moving the upper die on the clamping type clamp 3 to the upper die frame, putting down the upper die, returning to the process of feeding the cleaned lower die which is put into the reinforcement cage, and enabling the lower die to enter a concrete feeding procedure. The crane returns to clamp the cleaned upper die on the upper die frame to the feeding area, and the lower die subjected to feeding is closed, so that the clamping and holding combined type clamp finishes one period of work, and a lower worker does not need to cooperate with a driver to independently finish the separation and displacement of the upper die and the lower die and the working procedure of closing the upper die and the lower die.

The above embodiments are only used for explaining the inventive concept of the present invention, and not for limiting the protection of the claims of the present invention, and all the insubstantial modifications of the present invention made by using the above inventive concept shall fall within the protection scope of the present invention.
