Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, firstly, to simplify the description and facilitate understanding, the opposite surfaces of the left arm 21 and the right arm 21 of the gripper 2 are both defined as inner surfaces, and the opposite surfaces of the left arm 21 and the right arm 21 of the gripper 2 are both defined as outer surfaces, that is:

lateral surface of the clamping arm 21: the left side surface of the left clamp arm 21 and the right side surface of the right clamp arm 21;

inner side surface of the clamping arm 21: the right side of the left arm 21 and the left side of the right arm 21.

The definitions of the inner side and the outer side of the clamping leg 22 and the self-damaging element 23 are the same as those of the clamping arm 21.

Example one

As shown in fig. 1 and 2, a track laying roller safety gripper 2 is a gripping part in a mechanical gripper 1 for gripping a track laying roller on an automatic track laying vehicle, and comprises two clamping arms 21 symmetrically arranged left and right and clamping palms 22 respectively belonging to the lower parts of the two clamping arms 21, and the gripping and placing of the roller are completed by the opening and closing of the two clamping palms 22 respectively belonging to the two clamping arms 21 symmetrically arranged left and right by the force exerted by a power cylinder. In order to avoid damage to the related parts above the clamping palm 22 due to overload caused by the clamping palm 22 strongly impacting hard objects or mistakenly grabbing heavy objects during improper operation, the upper clamping arm 21 is disconnected from the lower clamping palm 22, and the clamping arm 21 and the clamping palm 22 are fixedly connected by a vulnerable part which is easy to break. Thus, by arranging the easily damaged part, when the gripping apparatus 2 is forced to collide with an object or is impacted by overload due to improper operation, the easily damaged part can be broken off at first, and the whole gripping mechanism can be protected.

The following is a further improvement.

The wearing part is a self-damage block 23, and a breaking groove 231 is formed in the self-damage block 23. The structural strength of the self-damage block 23 at the grooving position is weakened by opening the breaking groove 231, so that the self-damage of the self-damage block under the condition of strong impact or overload is realized.

The self-damage block 23 is fixedly connected with the clamping arm 21 and the clamping palm 22 on the outer side surfaces of the clamping arm 21 and the clamping palm 22 respectively, and the breaking groove 231 is formed in the inner side surface of the self-damage block 23. The arrangement does not affect the impact fracture, and is more favorable for overload fracture, because the lower end is a furling angle when the clamping palm 22 grabs the object, the overweight object has a strong downward sliding trend under the action of gravity during overload, and large outward component force can be generated on the inner side surfaces of the two clamping palms 22 with furling angles, so that the self-damage block 23 can be fractured at the inner side surface provided with the fracture groove 231.

The break groove 231 is a v-shaped groove. Such grooves tend to break the self-damaging block 23 upon impact and overload.

The distance between clamping legs 22 of the clamping arms 21 is larger than 10 mm. Such a distance is not only to ensure that the clamping arms 21 and the clamping legs 22 can be broken if necessary, but also to avoid that the clamping arms 21 and the clamping legs 22 collide immediately after the self-damaged block has been broken by impact due to too small a distance between the clamping arms 21 and the clamping legs 22.

The self-damage block 23 is connected with the clamping arm 21 and the clamping palm 22 through the bolt 4. The arrangement is convenient for disassembly and replacement when necessary.

Example two

As shown in fig. 3, the difference from the first embodiment is that the breaking grooves 231 are formed on the inner side surface and the outer side surface of the self-damaged block 23, which is advantageous in that the left and right self-damaged blocks 23 can be broken in the same direction.

The above-described embodiments are intended to illustrate the utility model more clearly and should not be construed as limiting the scope of the utility model covered thereby, any modification of the equivalent should be considered as falling within the scope of the utility model covered thereby.
