Description

DESCRIPTION Horizontal three-piece elongated support leg sliding pull system Technical Area The invention has been found in telescopic boom and folding boom cranes in extending and shortening support legs. relates to the sliding pull system used` In particular, the invention supports telescopically by opening and closing synchronously. with a compact structure that allows its feet to lengthen and shorten with a single piston It is related to the horizontal three-piece elongated support leg sliding traction system.

State of the Art Today, machinery, equipment, etc. telescopic boom for transporting large tonnage loads and folding boom truck cranes are widely used. telescope with boom support of the crane during the operation of the cranes and folding boom cranes on the vehicle. point as far as possible from the ring gear against the moment occurring in the ring gear. should be kept at a remote location. Therefore the telescope is boom and folding support legs are used in boom cranes and said support legs, During the operation of telescopic boom and folding boom cranes, the ground is opened. placed in the appropriate position.

The support legs used in the current technique are three in three horizontal axis in terms of general structure. It opens and closes by sliding and pulling at the level. It's riding and pulling Its movement is a hydraulic piston with three hydraulic pistons placed in the support legs. carried out by the mechanism. However, there is not enough in the support legs. Since there is not enough space, the mechanism that performs the driving and pulling operation Placing it in the support leg during the assembly phase causes a loss of time in production. and causes high costs. Besides, the three-piston There is a serious problem in the crane structure due to the mechanism and the hydraulic lines of these pistons. cost and extra weight. At the same time, that mechanism that affect the operation of the system due to the fact that it occupies a lot of space in the support leg. connecting the cables of the hydraulic line and the power line outside the support leg required. For this, external drums are used.

In addition, the cables of the hydraulic line and the electric line carried outside the support leg, It can be exposed to factors and easily broken down. Therefore, failure during the operation of cranes with telescopic booms or folding booms due to Although losses occur, the transportation of hydraulic lines out of the support leg Occupational accidents may occur in the event of a possible explosion due to an explosion.

As a result, the existence of the above problems and the inadequacy of the existing solutions made it necessary to make a development in the technical field.

Purpose of the Invention The present invention eliminates the above-mentioned disadvantages and three pieces of horizontally elongated support legs that bring new advantages to the field relates to the system.

To open and close by entering into the main sleeve rail (10) and into the piston sleeve (20). Piston sleeve inside the 1st rod (30) and 1st rail (11) that open and close the 1st rail (11) by means of The 2nd rod (40) that opens and closes the 2nd rail (12) by entering into (20) and opening and closing. has been contacted. The opening and closing movement of the 3rd rail (13) is during the opening movement of the 2nd rail (12). 1st pulley connected to the 2nd rail (12) during the closing movement of the rope (50) and the 2nd rail (12) (70) by means of pulling chain or rope (60) which closes the 3rd rail (13) by pulling has been provided. Organized chain (100) moving back and forth within the rail (110) connected to the 1st rail (11) is located. Hydraulic line (80) that enables the movement of the 1st rod (30) and the 2nd rod (40) and the electrical line (90), which provides the electrical connections of the support leg, the organizing chain It moves in (100). At the same time, said hydraulic line (80) and power line (90) is connected to the 3rd rail (13) passing through the right and left of the 2nd reel (120) it is connected to the pipe (130). Thus the hydraulic line (80) and the electrical line (90) (13) has been reached.

The working principle of the sliding traction system, which is the subject of the invention, is as follows; Hydraulic line inside the piston sleeve (20) to open the drag pull system. the push chain on the 2nd roller (120) connected to the 3rd rail (13) during its opening or opens the rope (50) by pushing the 3rd rail (13). Thus, the support leg (pictured) not shown) elongation is provided.

During the closing of the sliding pull system, the 1st rod (30) is closed and the 1st rail (11), the main it closes by pulling on the sleeve rail (10). Then the 2nd rod (40) is closed and the 2nd rail (12) is the 1st rail. (11) pulls it in and closes it. During the closing of the 2nd rail (12), it is connected to the 2nd rail (12) pulls it in.
