[0002] The guide rod type diesel pile hammer is a pile foundation construction machinery and equipment for building foundation engineering with large impact force, high working efficiency, strong reliability, and convenient use and maintenance. When the guide rod type diesel pile hammer is started, the landing gear and the hammer hook slide down along the guide rod, and the hammer hook under the landing gear hooks the pin shaft in the cylinder hammer. 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 unhooking lever on the landing gear through the rope to separate the hammer hook under the landing gear from the pin shaft in the cylinder hammer, and the cylinder hammer falls freely to complete the start of the guide rod type pile hammer. Therefore, each time the existing guide rod type diesel pile hammer is restarted, the landing gear hammer hook and the cylinder hammer pin shaft must be unhooked by manpower, which not only increases the labor intensity and labor cost; there are also certain safety hazards, which are easy to cause personnel and equipment injuries.

DETAILED DESCRIPTION

[0016] like Figure 1 , Figure 2 , Figure 3 and Figure 4The block-type automatic uncoupling diesel pile hammer shown in the figure adopts the guide rod diesel pile hammer commonly used in the market as the main structure, which includes two parallel guide rods 10, and the top cross beam 9 and the lower cross beam 15 are fixedly installed at the upper and lower ends of the two guide rods 10, respectively. The top cross beam 9, the lower cross beam 15 and the two parallel guide rods 10 form a rectangular frame structure. A piston 14 is fixedly installed on the lower cross beam 15, and the piston 14 and the lower cross beam 15 are cast into an integral structure. A cylinder hammer 13 is slidably installed on the guide rod 10, and the cylinder cavity of the cylinder hammer 13 can be sleeved on the piston 14. A landing gear 12 is also movably arranged on the guide rod above the cylinder hammer 13, and the guide hole on the landing gear 12 sleeved on the guide rod 10 is movably sleeved with the guide rod with a gap, so that the landing gear 12 can slide up and down along the guide rod 10.

[0017] The upper end of the landing gear 12 is hinged with a lifting pulley, and the wire rope wound on the lifting pulley is connected to the main winch. A cylinder hammer hook 1 and a hammer hook swing rod 4 are hingedly supported on the landing gear 12 through a hammer hook pin 3. The cylinder hammer hook 1 and the hammer hook swing rod 4 are fixedly connected to each other or are an integral structure. A hammer hook spring 11 is tensionedly arranged between the hammer hook swing rod 4 and the landing gear 12. The hammer hook spring 11 can also be tensioned between the cylinder hammer hook 1 and the landing gear 12. The hammer hook spring 11 adopts a cylindrical helical spring.

[0018] A block support rod 8 is arranged parallel to an outer side of the guide rod 10, and the two ends of the block support rod 8 are respectively fixed to the outer sides connected to the top cross beam 9 and the lower cross beam 15. A movable block 7 is hinged on the block support rod 8, and a fixed block 6 is also fixedly installed on the block support rod 8. The position of the fixed block 6 corresponds to the position of the movable block 7 to limit the flipping angle of the movable block 7. The extended end of the hammer hook swing rod 4 can touch the movable block 7 and be arranged opposite to it. The top surface of the hook portion of the cylinder hammer hook 1 is an inclined surface so that its hook portion can pass over the hammer lifting pin 2 and hook the cylinder hammer 13.

[0019] like Figure 1 As shown, the landing gear 12 hooks up the cylinder hammer 13, and when it moves upward along the guide rod 10 under the action of the main winch, when the extended end of the hammer hook swing rod 4 hits the movable block 7, the movable block 7 flips and rests on the fixed block 6. Restricted by the fixed block 6, the movable block 7 cannot continue to swing and flip. At this time, the hammer hook swing rod 4 is blocked by the movable block 7, forcing the hammer hook swing rod 4 and the cylinder hammer hook 1 to swing around the hammer hook pin 3, so that the lifting hammer pin 2 is separated from the cylinder hammer hook 1, and the cylinder hammer 13 is quickly sleeved to the piston 14 under the action of gravity to complete the start of the pile hammer.

[0020] like Figure 2 As shown, after the cylinder hammer 13 is unhooked, the extended end of the hammer hook swing rod 4 can pass over the movable block 7, and the landing gear 12 continues to move upward so that the next hook hammer can be started.

[0021] like Figure 3As shown, when the pile hammer needs to be started again, the landing gear 12 moves downward, the extended end of the hammer hook swing rod 4 on the landing gear 12 hits the movable stopper 7 from top to bottom, the movable stopper 7 flips upward and leaves the fixed stopper 6, and the extended end of the hammer hook swing rod 4 passes over the movable stopper 7 and continues to move downward. After the extended end of the hammer hook swing rod 4 passes over the movable stopper 7, the movable stopper 7 is reset under the action of the stopper reset spring 5 and rests on the fixed stopper 6 again.

[0022] like Figure 4 As shown, when the landing gear 12 continues to descend to the top of the cylinder hammer 13, the top inclined surface of the cylinder hammer hook 1 on the landing gear 12 passes over the hammer lifting pin 2 on the cylinder hammer 1, and under the action of the hammer hook spring 11, it firmly hooks the hammer lifting pin 2, so that the cylinder hammer 13 is lifted up together when the landing gear 12 goes up, and is ready for the next restart.

[0023] The above lists the preferred embodiments of the utility model, but the utility model is not limited thereto, and many improvements and changes can be made without violating the basic principles of the utility model. For example, the cylinder hammer hook and the hammer hook swing arm are fixedly connected to each other, and the hammer hook pin is swingably installed on the landing gear. The hammer hook swing arm can be a straight rod or a curved rod. In addition to the rod structure, the block support rod can also be a cable and other corresponding rod frame structures. The block support rod can also be installed on the top crossbeam at one end, or installed on the piston at one end. The number and installation spacing of the movable block and the fixed block should be selected and determined according to factors such as the pile driving environment and the striking energy. And so on. These improvements and changes all fall within the protection scope of the utility model.
