FIG. 1 is a schematic structural view of a track link for a two-section vehicle of the present invention.

The symbols in the drawings illustrate that: 1. a lead screw; 2. hooking claws; 3. a connecting pin; 4. an iron chain; 5. a locker; 6. a ratchet wrench; 7. an iron chain hook.

Detailed Description

The present invention will be described in detail with reference to the following preferred embodiments.

As shown in figure 1, the track connecting mechanism for the double-section vehicle comprises a claw 2, a lead screw 1, a locker 5 and an iron chain 4. The claw 2 is used for hooking the middle position of the front face of one to-be-connected track shoe of the track when in use, and the iron chain 4 is used for winding the other to-be-connected track shoe.

One end of the hook claw 2 is provided with a connecting pin 2 which is fixedly connected with one end of the screw rod 1. After the connecting pin 2 is fixedly connected with one end of the screw rod 1, the hook claw 2 can freely rotate around the screw rod 1. The other end of the hook claw 2 is provided with a circular arc hook-shaped structure.

Be provided with the external screw thread on the lead screw 1, be provided with the internal thread on the locker 5 for link to each other with the external screw thread on the lead screw 1, make locker 5 can rotate on lead screw 1, in order to carry out axial motion along lead screw 1. The locking device 5 is fixedly connected with a ratchet wrench 6, a clamp spring is arranged on the ratchet wrench 6, and the clamp spring can be clamped on the lead screw 1 and used for limiting the movement of the locking device 5. The ratchet wrench 6 is further provided with a shift button, which includes two shift positions, namely a forward shift position allowing the locker 5 to rotate forward relative to the screw rod 1 and a reverse shift position allowing the locker 5 to rotate reversely relative to the screw rod 1.

The number of the iron chains 4 is two, one end of each of the two iron chains 4 is fixed on the locker 5, and the other end of each of the two iron chains 4 is fixed with the iron chain hook 7. Specifically, the rear portion of the locker 5 has an iron chain fixing groove for fixing the iron chain 4.

When the track connecting mechanism for the double-section vehicle is used, the operation steps are as follows:

1. overlapping the butt joint of the crawler belt to a proper position, and hooking the middle position of the front side of the crawler belt plate of the crawler belt by using a hook claw 2 at one end and stably hanging; and straightening the iron chain 4 at the other end, winding the iron chain 4 at the left side and the right side of the track shoe in an annular manner, adjusting the position to an effective stroke position, and hooking the track shoe by using an iron chain hook 5 to fix the iron chain 4. In the using process, the ratchet wrench 6, the locker 5, the hook claw 2, the iron chain 4 and the iron chain hook 7 are hung from the inner side of the track shoe from top to bottom in a hanging mode, the hanging mode is to avoid influencing the subsequent mounting of the track shoe and avoid the conditions of obstruction and insufficient space when the iron chain or the locker and the track shoe are mounted.

2. Adjust ratchet spanner 6's gear button to corotation position, rotate ratchet spanner 6, make locker 5 rotatory with lead screw 1 corotation, and then make locker 5 shorten with lead screw 1's effective stroke for taut iron chain 4 can pull the track that needs to connect in effectual stroke, can carry out effectual connection until track both ends.

3. After bolts are arranged at the connection position of the crawler belt, the adjusting button on the ratchet wrench 6 is adjusted to a reverse gear, the ratchet wrench 6 is rotated to enable the locker 5 and the lead screw 1 to rotate reversely until the hook claw 2 and the iron chain hook 7 can be easily taken down, and the operation task is completed satisfactorily.

The utility model adopts a 'hook claw-chain' and a 'locker-screw' device, overcomes the problems of clumsy tools and a large amount of manpower when the double-section vehicle is connected under normal conditions or tracks in special terrains, ensures that the tracks are connected conveniently, quickly, stably and reliably, and realizes the problem that the double-section vehicle tracks are accidentally broken and cannot be connected.

The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the utility model. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
