CS241765B1 - Swivel cap for pile driving - Google Patents

Abstract

The rotating cap for driving sheet piles can be fixed in the cap carrier in a rotated position. The cap carrier is provided with a circular frame with suspension eyes and a hole for a locking pin. A 'cap in the form of a hoop with a firmly attached support plate at the bottom is inserted into the circular frame, in the inner space of which a damping filling is spread on the support plate and covered with a cover sheet. The support plate of the cap is firmly connected to the profiled sheet pile driver at the bottom and at one quarter of the circumference is provided with adjustment holes, into one of which the locking pin of the circular frame of the cap carrier is inserted. The upper circumference of the cap hoop is provided with a closing ring, detachably connected to a split ring mounted on an asymmetrical system of springs, mounted on the washers of the circular frame of the cap carrier. The rotating cap is also suitable for driving directional piles of square cross-section, forming a system of supporting pillars for the grid foundation structure of buildings.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention

When using sheet pile driving, it is necessary to maintain their prescribed orientation to the terrain · When using a fixed cap and a constant boom setting, the chassis of the sheet pile driving must move only on a single fixed path, at a constant practically maximum distance from the pile wall to be built. · In the case of uneven terrain, natural obstacles such as watercourses, protected vegetation, etc., or in the presence of transport or construction objects in the chassis route, it is necessary to turn the boom, change the strut length as a rule by dismantling and replacing it longer or shorter and also change the travel route, often a complex taxiing route, or take building measures to eliminate the negative effects of terrain and / or obstacles. All these operations considerably prolong the construction process and increase construction costs.

These drawbacks are eliminated by a pile driving pile rotatable in a cap carrier provided with a circular frame with hinged eyes and an insertion hole, wherein a ring in the form of a hoop is inserted into the circular frame with at least one spring with a firmly attached support plate, in which the damping pad covered by a cover sheet according to the invention is spread on the cap support plate according to the invention, characterized in that the cap support plate is fixedly connected underneath the profiled sheet feeder and is provided with adjusting holes at one quarter of the circumference wherein the hinge pin of the cap frame of the cap carrier is inserted, while the upper circumference of the cap frame is provided with a closure ring detachably connected to a split support ring mounted on an asymmetric spring assembly mounted on the washers of the cap frame of the cap carrier.

The main advantage of the swivel cap is that, in difficult terrain conditions, it allows to choose the most advantageous travel route of the chassis by the pile driving, guided outside the spacious obstacles, as it allows to select any rotation of the boom © against the sheet pile.

In the accompanying drawing, FIG. 1 is a side view and a partial cross-section of the rotatable cap; FIG. 2 is a plan view and a partial cross-section of the rotatable cap of the invention.

Example

The pile pile swiveling cap is mounted in a cap carrier 2 provided with a circular frame 3 with hinged lugs 4 and a bore 5 for the locking pin 5, and a ring 9 in the form of a hoop with fixed support attached underneath a plate in which the damping pad 10 is covered by a cover sheet 11 on the backing plate of the cap 9. The backing plate of the cap 9 is rigidly connected to the profiled sheet feeder 12 underneath and is provided with adjusting holes 13 at one quarter of the circumference. the securing bolt 5 of the circular frame 3 of the bolt carrier 2 is inserted. The upper circumference of the rim of the cap 9 is provided with a closing rim 8, releasably connected to a split support ring 7 mounted on an asymmetric spring system 6 mounted on the washers of the ring frame 3 of the cap carrier.

The swiveling cap 9 can be adjusted in the annular frame 3 after removal of the locking pin 5 so that the sheet pile feeder 12 occupies a position perpendicular to the travel direction of the pile driver by its axis of symmetry.

In this adjusted position, the pivot pin 9 is secured by inserting the locking pin 5 into the respective setting hole 13 of the support plate of the pin 9. This aligns the axis of the sheet pile to be built with the chassis travel path of the pile driver. The distribution of the asymmetrical spring system 6 corresponds to the asymmetrical distribution of the weight of the carrier 2 relative to the axis of the hammer striking part.

- 3 Pile driving pivot is also suitable for pile driving, especially for pile driving of rectangular piles of square section, forming a system of supporting pillars for slatted foundation construction of buildings *
