Description

Technical Field

[0001] The invention relates to a guide rod type diesel pile hammer, in particular to a guide rod type diesel pile hammer capable of realizing automatic hook hammer lifting and automatic drop hammer starting. Background Art

[0002] The guide rod type diesel pile hammer is mainly composed of a piston, a cylinder hammer, a top cross beam, a guide rod, and a landing gear with a hammer hook. The top cross beam and the piston are respectively fixed to the upper and lower ends of the guide rod, and the landing gear and the cylinder hammer are slidingly supported on the guide rod; the main function of the hammer hook and the landing gear is to start the guide rod type diesel pile hammer at the beginning of piling, and the landing gear is also the suspension structure of the entire pile hammer when the pile hammer is in the hanging working state.

[0003] When the guide rod diesel pile hammer is started, the landing gear and the hammer hook slide down along the guide rod, the hammer hook under the landing gear hooks the pin in the cylinder hammer, and the winch cable lifts the landing gear and the cylinder hammer upward at the same time. After the cylinder hammer reaches a certain height, the ground operator pulls the cylinder hammer hook on the landing gear through the rope to separate the cylinder hammer hook under the landing gear from the pin of the cylinder hammer, and the cylinder hammer falls freely to complete the start of the guide rod type pile hammer. However, with the increase of the striking energy of the guide rod type diesel pile hammer, the weight of the cylinder hammer of the pile hammer also increases significantly. The huge mass of the cylinder hammer will inevitably produce great friction resistance between the hammer hook and the cylinder hammer pin, making it very difficult and complicated to unhook and start the cylinder hammer. Every time the pile hammer is restarted, it is necessary for several people to pull the rope under the command of the commander to complete the unhook start of the cylinder hammer, or to add a special winch equipment to drag the hammer hook start rope to complete the start operation of the pile hammer. Since each restart of the pile hammer requires the uncoupling operation of the landing gear hammer hook and the cylinder hammer pin to be completed by manpower or mainly by manpower, not only the labor intensity and labor cost are greatly increased; and such a starting operation has great safety hazards and is likely to cause personal and equipment injury accidents. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a guide rod type automatic uncoupling diesel pile hammer which can realize automatic uncoupling and starting of the cylinder hammer without the need for manual uncoupling operation.

[0005] In order to solve the above technical problems, the guide rod type automatic uncoupling diesel pile hammer of the present invention comprises a piston, a guide rod, a cylinder hammer and a top cross beam, the piston and the top cross beam are respectively fixedly mounted on the two ends of the guide rod, the cylinder hammer is slidably mounted on the guide rod, a landing gear is also slidably mounted on the guide rod, a cylinder hammer hook is rotatably supported on the landing gear, an uncoupling bracket is fixedly mounted on the top cross beam and / or the piston, and an uncoupling component is mounted on the uncoupling bracket; one end of the cylinder hammer hook is a hook hammer end, and the other end of the cylinder hammer hook is a swing rod end, and the swing rod end of the cylinder hammer hook corresponds to the position of the uncoupling component.

[0006] Preferably, the decoupling member adopts a plate structure.

[0007] Preferably, the decoupling member in a plate-like structure is parallel to the guide rod, and a guide folded edge is provided at the lower end of the decoupling member.

[0008] Preferably, the decoupling member in a plate-like structure and the guide rod are arranged to be inclined relative to each other.

[0009] Preferably, the decoupling member adopts a bump block structure.

[0010] Preferably, a hammer hook swing limit surface is provided on the landing gear, and the hammer hook swing limit surface can limit the swing amplitude of the cylinder hammer hook.

[0011] Preferably, the swing rod end of the cylinder hammer hook is a sliding contact end, or a hammer hook roller is rotatably mounted on the swing rod end.

[0012] Preferably, the plane where the cylinder hammer hook is located is parallel or perpendicular to the plane where the two guide rods are located.

[0013] Preferably, a hammer hook spring is installed between the cylinder hammer hook and the landing gear; and a landing gear lifting pulley is rotatably supported on the landing gear.

[0014] Preferably, a lifting hammer pin is fixedly installed on the cylinder hammer, and a pin swivel sleeve is movably mounted on the lifting hammer pin, and the hook hammer end of the cylinder hammer hook can hook the lifting hammer pin through the pin swivel sleeve; the unhooking bracket includes two parallel vertical poles, and the unhooking component is fixedly installed on the two vertical poles.

[0015] In the above structure, since a decoupling component is fixedly installed on the decoupling bracket, and the swing arm end of the cylinder hammer hook hinged on the landing gear corresponds to the position of the decoupling component, when the cylinder hammer hook falls along the guide rod with the landing gear, the cylinder hammer hook automatically hooks the hammer lifting pin and lifts the cylinder hammer; when the cylinder hammer is lifted to the position of the decoupling component, the decoupling component fixedly installed on the decoupling bracket forces the cylinder hammer hook to swing around the hammer hook pin so that the hook hammer end of the cylinder hammer hook is separated from the cylinder hammer pin, causing the cylinder hammer to fall and sleeve onto the piston to complete the starting of the pile hammer. This starting process is achieved by the power of the main winch of the hammer lifting machine. It does not require manpower to pull the hammer hook lever to achieve the decoupling operation, nor does it require the addition of special decoupling winch equipment. It not only reduces human intervention and manual operation, reduces labor cost and labor intensity, but also realizes the automatic operation of cylinder hammer decoupling, avoiding safety accidents of personnel and equipment during the starting operation. When the unhooking component adopts a strip plate structure, the rocker end of the cylinder hammer hook keeps sliding on the plate unhooking component during the upward process of the landing gear, so that the hook hammer end of the cylinder hammer hook is always in the unhooking position, thereby avoiding the cylinder hammer from accidentally bouncing to form a destructive "hook" phenomenon. The technical solution of the present invention cleverly fixes the unhooking component on the unhooking bracket to realize automatic hooking and unhooking operations, which is not only suitable for the manufacture of new hammers, but also convenient for the transformation of existing pile hammers; in this technical solution, the main winch still provides the cylinder hammer unhooking power, so that the pile hammer's starting, lifting and hoisting actions are all completed by the same main winch, reducing the auxiliary equipment used by the pile hammer, and is more suitable for the pile hammer's hoisting operation. The present invention does not actually change the basic structure of the cylinder hammer hook, but only adds a unhooking bracket and an unhooking component. The structure is simple and reasonable, and it is easy to install and manufacture. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] like Figure 1 , Figure 2 The guide rod type automatic uncoupling diesel pile hammer shown in the figure comprises a piston 1, a top cross beam 7, a guide rod 2 and a cylinder hammer 3. The lower end of the guide rod 2 is fixedly mounted on the piston seat of the piston 1, the top cross beam 7 is fixedly mounted on the upper end of the guide rod 2, there are two guide rods 2, the cylinder hammer 3 is slidably mounted on the two mutually parallel guide rods, and a landing gear 4 is also slidably mounted on the two parallel guide rods 2, the landing gear 4 is located above the cylinder hammer 3, and the cylinder hammer 3 and the landing gear 4 are both located between the piston 1 and the top cross beam 7. A cylinder hammer hook 10 is rotatably supported on the landing gear 4 through a hammer hook pin shaft 12, a lifting hammer pin shaft 9 is arranged on the cylinder hammer 3, a pin shaft rotating sleeve is rotatably mounted on the lifting hammer pin shaft 9, and the cylinder cavity of the cylinder hammer 3 can be sleeved toward the piston body of the piston 1. A landing gear lifting pulley 5 is rotatably supported on the landing gear 4, and the plane where the landing gear lifting pulley 5 is located is the same plane as the plane where the cylinder hammer hook 10 is located or on planes parallel to each other, and the plane where the landing gear lifting pulley 5 is located and the plane where the cylinder hammer hook 10 is located are perpendicular to the plane where the two guide rods 2 are located; of course, the plane where the landing gear lifting pulley 5 is located and the plane where the cylinder hammer hook 10 is located can also be parallel to the plane where the two guide rods 2 are located, or on a plane parallel to the plane where the two guide rods 2 are located; it can also be that the plane where the landing gear lifting pulley 5 is located and the plane where the cylinder hammer hook 10 is located intersect with the plane where the two guide rods 2 are located at an angle.

[0028] One end of the cylinder hammer hook 10 relative to the rotation hinge fulcrum (the axis of the hammer hook pin 12) is the hook hammer end, the hook portion of which can hook the lifting hammer pin 9, and the hook hammer end is also provided with a counterweight portion, and a hammer hook spring 11 is installed between the extended swing arm of the cylinder hammer hook 10 and the landing gear 4, so that when the cylinder hammer hook 10 hooks the lifting hammer pin 9, it can firmly hook the lifting hammer pin 9 to prevent accidental unhooking. The other end of the cylinder hammer hook 10 is an outwardly extended swing arm end, which extends to the relative position of the unhooking component 8, so that it can touch the unhooking component 8 during the upward movement of the cylinder hammer hook 10.

[0029] like Figure 1 , Figure 2 As shown, the hook hammer end of the cylinder hammer hook 10 hooks the hammer lifting pin 9 on the cylinder hammer 3, the landing gear lifting pulley 5 drags the landing gear 4 and the cylinder hammer hook 10 thereon upward, and the cylinder hammer hook 10 hooks the cylinder hammer 3 and moves upward along the guide rod 2. A decoupling bracket 6 is vertically installed between the seat body of the piston 1 and the top cross beam 7. The decoupling bracket 6 includes two parallel vertical rods. The decoupling member 8 is fixedly installed between the two parallel vertical rods. Of course, the decoupling bracket 6 can also be a vertical rod for installing the decoupling member 8. The vertical rod of the decoupling bracket 6 can also be fixedly connected to the top cross beam or the piston at one end.

[0030] The unhooking member 8 is a strip plate structure, and a bent guide fold is provided at the lower end of the strip plate to reduce the contact impact force between the swing arm end of the cylinder hammer hook 10 and the unhooking member 8. Of course, the unhooking member 8 of the strip plate structure may not be provided with a guide fold, and in this case, the unhooking member 8 may be installed on the unhooking bracket 6 at an angle relative to the guide rod 2.

[0031] The unhooking member 8 may not only adopt a strip plate structure, but also a columnar, block or short plate structure.

[0032] like Figure 3 As shown, the landing gear lifting pulley 5 drags the landing gear 4 and the cylinder hammer hook 10 thereon upward. When the extended rocker arm end of the cylinder hammer hook 10 touches the unhooking component 8, the unhooking component 8 blocks the rocker arm end of the cylinder hammer hook 10 from moving upward, and forces the cylinder hammer hook 10 to rotate counterclockwise around the hammer hook pin 12, so that the hook hammer end of the cylinder hammer hook 10 is separated from the lifting hammer pin 9 of the cylinder hammer 3, and the cylinder hammer 3 is sleeved onto the piston along the guide rod 2 under the action of gravity.

[0033] like Figure 4 As shown, after the cylinder hammer hook 10 and the cylinder hammer 3 are separated, the swing rod end of the cylinder hammer hook 10 still slides on the sliding surface of the strip-shaped unhooking member 8 for a distance, so that the hook hammer end of the cylinder hammer hook 10 remains in the unhooked state to avoid the accidental bounce of the cylinder hammer 3, which would cause a destructive "hooking" phenomenon and damage the equipment. The cylinder hammer 3 continues to move downward under the action of gravity until the cylinder cavity of the cylinder hammer 3 is sleeved on the piston 1, so as to complete the automatic start of the pile hammer.

[0034] like Figure 5 As shown, the lower end of the unhooking member 8 fixedly mounted on the vertical rod of the unhooking bracket 6 is provided with a guide folding edge, and the swing rod end of the cylinder hammer hook 10 is a sliding contact end of an arc surface. A hammer hook spring 11 is installed on the swing rod of the swing rod end of the cylinder hammer hook 10.

[0035] like Figure 6 As shown, the difference from the above embodiment is that a hammer hook roller 13 is installed at the swing rod end of the cylinder hammer hook 10 to reduce the contact collision force and contact friction force between the cylinder hammer hook 10 and the unhooking component 8.

[0036] like Figure 7 , Figure 8 and Fig. 9 As shown, the two sides of the landing gear 4 are guide rod holes so that the landing gear 4 can be slidably supported on the guide rod 2, and the top of the landing gear 4 is rotatably supported by the pulley pin 14 with the landing and lifting pulley 5. The cylinder hammer hook 10 is hinged on the frame of the landing gear through the hammer hook pin 12, and a hammer hook swing limit surface 15 is also provided on the frame of the landing gear 4 to limit the upward swing angle of the swing rod end of the cylinder hammer hook 10, so that the cylinder hammer hook 10 can accurately hook the cylinder hammer 3 upper hammer pin 9 when the hook hammer of the landing gear 4 goes down. The hammer hook swing limit surface 15 can be an edge-shaped blocking surface of the landing gear 4 frame, or a blocking surface of a convex block provided on the landing gear 4 frame.

[0037] The above only lists some preferred embodiments of the present invention, but the present invention is not limited thereto, and many improvements and changes can be made. As long as the improvements and changes are made on the basis of the basic principles of the present invention, they should be regarded as falling within the protection scope of the present invention.
