Embodiment Construction

[0031] exist figure 1 shows a drop weight 1 , which is guided in a vertical direction 2 in a guide tube 3 . The conduit 3 is equipped with two bearing housings 4 each surrounding the conduit 3 and interconnecting the sections 3 a , 3 b and 3 c of the conduit 3 to form the conduit 3 . The connection of the sections 3a, 3b and 3c is realized via flanges on the bearing housing 4, such as figure 2 shown. as Figure 2 to Figure 4 As shown, the bearing housing 4 is equipped with four sliding parts 5 made of plastic, which are arranged inside four mounting openings 6 in the mounted state. The four mounting ports 6 are arranged in pairs opposite to each other, and are distributed at intervals of 90° along the periphery of the bearing housing 4 . In the installed state ( Figure 4 ), the four sliders 5 are fixed in the four installation ports 6 through the four supporting members 7 .

[0032] The slide 5 has a cylindrical peripheral surface 8 which is accommodated and supported ...

Abstract

The invention relates to a linear guide for the falling weight (1) of a pile hammer, having at least one bearing housing (4, 24) at least partially enclosing the falling weight (1), that can be designed according to the invention without lubricant, in that the bearing housing (4, 24) has sliding elements (5, 25) preferably made of plastic and contacting the falling weight (1) in order to guide said weight, and that can be installed and removed while the falling weight (1) is installed.

Description

technical field [0001] The invention relates to a linear guide for a drop hammer of a pile driver, which has at least one bearing housing which at least partially surrounds the drop hammer. Background technique [0002] In infrastructure work, such pile drivers are used for driving piles on the ground, especially at the bottom of bodies of water. At this time, for pile driving, the drop hammer is periodically raised and lowered to drive the pile into the ground. The drop hammer itself is guided in the linear guides of the pile driver, where it can move up and down in a straight line along the axial direction. Known pile drivers have linear guides made of metal and the required lubricants in order to guide the vertical movement of the drop hammer with as little friction and wear as possible. When pilings are driven underwater, lubricants may enter the water body, contaminating the water. Contents of the invention [0003] The object of the present invention is to propose...
