Abstract

Provided is a pipe hammer that can be driven straightly with less fatigue. A pipe hammer characterized in that a weight 2 is provided at the tip of a gripping pipe 1. Since the piles and struts are passed through the pipe, the pipe is swung up and down, and the pile head is struck and driven, so there is less fatigue and it can be driven straight and farm work can be reduced. [Selection] Figure 1

Description

  The present invention relates to a pipe hammer that is used by driving through a gripping pipe when driving piles or struts in agricultural work.

In farm work, there are relatively many works of driving piles and struts when making fences and laying ropes. It was common to use a swing-down hammer to drive these piles and pillars.
Japanese Patent Laid-Open No. 09-206878

  In the case of this swing-down hammer, there is a disadvantage that hands are tired, and that piles and pillars are not driven straight, but become slanted, which causes inconvenience and time. Was.

  The inventor has arrived at the present invention as a result of various studies in view of this point. The present invention attaches a weight (2) to the tip of the pipe (1) as shown in FIG. 2. Grasping pipe (1) and swinging pipe (1) up and down through pipe (1) into pipe (1) as shown in FIG. Completed the pipe hammer.

  Also, if this pipe hammer is raised too much when driving, the pile head will fall out of the gripping pipe (1), causing a risk of swinging, and as shown in the figure, a safety string (5) is attached to the lower end of the swinging pipe (1). The clip (4) is attached to the tip of the string (5) and fixed to the middle of the pile to limit the excessive swinging of the pipe hammer.

  Shaking your hands up and down reduces fatigue, and you can hit straight when you drive, so there is no waste. For this reason, the operational effect is particularly remarkable.

  The present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view showing an entire pipe hammer, and FIG. 2 shows a pipe hammer provided with a safety string (5).

  In FIG. 1, (1) shows a grip pipe, and is constructed by attaching a weight (2) to the head end of the grip pipe (1). The diameter of the pipe (1) is appropriately about 5 cm in consideration of the size of piles and columns used in farm work, and the weight of the weight is an iron ingot of 1.8 kg.

The length of the grip pipe (1) is 50cm, but if you shake your hand vigorously during the driving operation, the pile (3) in the pipe (1) will come off and there is a danger of hitting the grip hand against the pile head To prevent this, attach a safety string (5) to the lower end of the gripping pipe (1) as shown in Fig. 2, and attach a clip (4) to the end of this string (5) to secure it to the pile (3). To do.
By providing the safety string (5) in this way, it is possible to prevent the pile (3) from coming out of the pipe (1) during striking, and to prevent the danger that the pile will fall out and hit the hand during work. Can do.

  Since this pipe hammer strikes up and down, it becomes possible to drive piles and struts straight, and the farming work can be carried out smoothly.

  As described above, the pipe hammer of the present invention has less hand swing and light fatigue compared to conventional hammers, and when driving, there is no bending of the pile, so it requires less work time, so an aging farmer The degree of utilization is large because farming can be reduced.
