Problems solved by technology
When the dynamic tamping machine is used for hoisting, dragline, and grab operations, sometimes it is necessary to increase the large lifting capacity, but the front of the dynamic tamping machine arm head protrudes long, which affects the lifting performance of the whole machine
[0003] like figure 2 As shown, the arm head structure in the prior art is a goose-head arm, and the arm head and the truss arm are a welded integral structure, the distance between the lifting pulley and the guide pulley is fixed, and the extension part of the arm head is too long, resulting in the main The moment the arm is subjected to is too large during the working process, which reduces the lifting performance of the equipment
For a dynamic compaction machine of the same tonnage, the shorter the protruding part, the greater the mass of the heavy object that can be lifted. This structure is not conducive to maximizing the lifting performance of the dynamic compaction machine, and is not conducive to other functions of the dynamic compaction machine except dynamic compaction. function discovery

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] Such as image 3 As shown, the arm head structure of the dynamic tamping machine includes the arm head 1 connected with the main arm 2 through the truss arm 5;
[0029] A guide pulley 6 and a lifting pulley 7 are installed on the arm head 1;
[0030] The arm head 1 and the lattice arm 5 are connected to each other;
[0031] An expansion mechanism 10 is provided at the connection between the front end of the arm head 1 and the truss arm 5 .
[0032] The arm head 1 and the truss arm 5 are refitted into an assembled integrated structure by connecting each other, and the distance between the lifting pulley at the front end of the arm head 1 and the truss arm 5 is adjusted by the expansion mechanism 10 to realize the expansion work of the arm head 1. status function.
[0033] Further, the arm head 1 is connected to the installation ear plate 2 9 welded on the top...

The invention discloses an arm head structure of a dynamic ramming machine and a dynamic ramming machine, comprising an arm head (1) connected to a main arm (2) through a truss arm (5); guide pulleys are installed on the arm head (1) (6) and lifting pulley (7); the arm head (1) and the truss arm (5) are connected to each other; the front end connection of the arm head (1) and the truss arm (5) is provided with an expansion mechanism (10). The arm head structure of the dynamic compaction machine and the dynamic compaction machine refit the arm head and the truss arm into an assembled integrated structure, and adjust the distance between the lifting pulley block and the arm frame by using the expansion mechanism of the connecting rod structure, shortening the lifting object and the arm frame The distance from the connecting hinge point of the turntable finally realizes the increase of the lifting capacity, which significantly expands the application range of the dynamic compaction machine.
Description
technical field [0001] The invention relates to an arm head structure, in particular to an arm head structure of a dynamic ramming machine and a dynamic ramming machine using the arm head structure. Background technique [0002] At present, the multi-functional crawler-type dynamic compaction machine is more and more widely used. It integrates various functions such as dynamic compaction, hoisting, dragline, and grab bucket, and is generally welcomed by users. In the existing technology, such as figure 1 As shown, the general dynamic compaction machine can lift the rammer to a certain height to compact the foundation during operation, and the weight of the heavy object it can lift has a maximum value. When the dynamic tamping machine is used for hoisting, dragline, and grab operations, sometimes it is necessary to increase the large lifting capacity, but the front part of the dynamic tamping machine arm head protrudes longer, which affects the lifting performance of the who...
