Abstract
The utility model discloses a track link connected by double hinge pins, and belongs to the technical field of heading machines. The track link connected by the double hinge pins comprises a plurality of track links, wherein every two adjacent track links are connected together through two hinge pins, the two hinge pins respectively penetrate into the two track links from the left sides and the right sides of the two adjacent track links, and the axial lines of the two hinge pins on the two adjacent track links coincide. By means of the track link connected by the double hinge pins, the two hinge pins penetrate into the left sides and the right sides between the two adjacent track links, the two hinge pins enable the two adjacent track links to be connected together, and thus the lengths of the hinge pins are shortened by a half than the lengths of existing hinge pins. Therefore, not only are the machining precision requirements of the hinge pins lowered so as to enable the two hinge pins to be conveniently and simply mounted on the two adjacent track links, but also the two hinge pins can flee left and right on the track links when force is exerted in the middles of the track links, so that stress is buffered, the damage to the hinge rolls is reduced, and service life is prolonged.
Description
Technical field
The utility model relates to a kind of development machine, the double pin axle connecting band track plate on espespecially a kind of development machine.
Background technology
To be connected with the bearing pin that track shoe width adapts by a length between the existing caterpillar block.Along with the increase of track shoe width, the length of bearing pin is also more and more longer.Because caterpillar block is smart Casting Parts, so the difficulty that bearing pin is installed between adjacent two caterpillar blocks is also more and more higher, and is installed on a bearing pin on two caterpillar blocks, its stressed time marquis is easily stressed concentrated, makes bearing pin fragile, and service life is short.
The utility model content
The purpose of this utility model is to provide a kind of double pin axle connecting band track plate, and it is easy for installation, save trouble, and the requirement on machining accuracy of its attaching parts reduces, attaching parts is not fragile, and prolong service life.
To achieve these goals, technical solution of the present utility model is: a kind of double pin axle connecting band track plate, comprise several caterpillar blocks, wherein link together by two bearing pins respectively between adjacent two described caterpillar blocks, two described bearing pins pierce in two caterpillar blocks from the left and right sides of two adjacent caterpillar blocks respectively, the dead in line of two bearing pins on adjacent two described caterpillar blocks.
The utility model double pin axle connecting band track plate, wherein the outside of two described bearing pins is respectively equipped with the resilient pin that stops bearing pin to skid off from caterpillar block, and two described resilient pins vertically pass respectively the caterpillar block in the outside.
After adopting such scheme, the utility model double pin axle connecting band track plate pierces into two bearing pins by the left and right sides between adjacent two caterpillar blocks, by two bearing pins adjacent two caterpillar blocks are linked together, like this length of bearing pin just than existing bearing pin length short half, the requirement on machining accuracy of bearing pin is reduced, make two bearing pins be installed on convenience on adjacent two caterpillar blocks, save trouble; And when the centre of caterpillar block is stressed, two bearing pins can be on caterpillar block left and right sides vibration, make stressed the buffering, reduced the damage of bearing pin, prolong service life.
Description of drawings
Fig. 1 is the front view of the utility model double pin axle connecting band track plate;
Fig. 2 is the left view of the utility model double pin axle connecting band track plate.
Below in conjunction with accompanying drawing, by embodiment the utility model is described further;
The specific embodiment
As depicted in figs. 1 and 2, the utility model double pin axle connecting band track plate comprises between 1, two caterpillar block 1 of two caterpillar blocks linking together by two bearing pins 2.Two bearing pins 2 pierce in two caterpillar blocks 1 from the left and right sides of two caterpillar blocks 1 respectively.The dead in line of two bearing pins 2 on two caterpillar blocks 1.The outside of two bearing pins 2 is respectively equipped with the caterpillar block 1 that 3, two resilient pins 3 of resilient pin that stop bearing pin to skid off from caterpillar block 1 vertically pass respectively the outside.
The utility model double pin axle connecting band track plate pierces into two bearing pins 2 by the left and right sides between two caterpillar blocks 1, by two bearing pins 2 two adjacent caterpillar blocks 1 are linked together, by two resilient pins 3 two bearing pins 2 are limited in two caterpillar blocks 1 again, two bearing pins 2 can not skidded off from caterpillar block 1, two bearing pins 2 and two caterpillar blocks 1 are linked together, since the length of the used bearing pin 2 of the utility model just than existing bearing pin length short half, the requirement on machining accuracy of bearing pin is reduced, and two bearing pins 2 are installed on two caterpillar blocks 1 and also make things convenient for, save trouble; And when the centre of caterpillar block 1 was stressed, two bearing pins 2 can make stressed the buffering in about 1 of caterpillar block vibration a little, have reduced the damage of two bearing pins 2, and prolong service life.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
