Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
Example 1
The self-locking synchronous clamp for the engineering machinery as shown in figure 1 comprises two oppositely arranged clamping blocks 2; the clamping block 2 is connected with a link mechanism 5, and the other end of the link mechanism 5 is connected and installed on a screw driving mechanism 6.
Example 2
Based on embodiment 1, and the link mechanisms 5 on the two gripper blocks 2 are mounted on opposite sides.
Example 3
Based on embodiment 1, and the clamping block 2 is slidably mounted in the connecting body 3.
Example 4
Based on embodiment 3, and the connecting body 3 is fixed by the mounting mechanism 4.
Example 5
Based on embodiment 3, and the connecting body 3 is relatively fixed by the fastening mechanism 1.
Example 6
Based on embodiment 1, the screw driving mechanism 6 is a structure in which a worm wheel rotationally drives a screw rod to move linearly.
Example 7
With reference to the above embodiments, specifically, the connecting device mainly comprises a fixing mechanism 1, a clamping block 2, a connecting body 3, an installation mechanism 4, a link mechanism 5 and a screw driving mechanism 6. The connecting body 3 is fixed at the lower mast part of a mast of the drilling machine through the mounting mechanism 4, the screw driving mechanism 6 is fixed at the lower end of the clamping device and is connected with the connecting rod mechanism 5 and the clamping block 2, and the connecting body 3 is tensioned left and right by the fixed connection structure 1 to prevent the drill rod from opening when being clamped. The screw driving mechanism 6 mainly utilizes a screw lifting principle to drive the screw rod to linearly move for the rotation of the turbine. The connecting rod mechanism 5 is driven to move up and down, and then the clamping block 2 is driven to move left and right, so that clamping is realized. The screw driving mechanism 6 is clamped compared with a hydraulic oil cylinder commonly used on an engineering drilling machine, the self-locking capacity is better, and the clamping synchronism is better. The two oil cylinders are adopted for clamping, so that the synchronism and the self-locking performance in the clamping process of the drill rod are difficult to guarantee, and if the synchronism is poor, risks such as hole collapse are easy to cause. If the self-locking property is poor, the drill rod is easy to loosen and fall off, and the screw driving mechanism 6 is adopted to drive the connecting rod mechanism to realize clamping, so that the clamping synchronism can be effectively ensured, and very reliable locking force is realized; the device has better economy, the whole cost is reduced by 30 percent compared with the clamping of the oil cylinder, and the speed is more stable and the stability is stronger in the clamping process.
The main working principle is as follows: the connecting body is fixed at the lower mast part of the mast of the drilling machine through an installation mechanism, the screw driving mechanism is fixed at the lower end of the gripper and is connected with the connecting rod mechanism and the gripper block, and the connecting body is tensioned leftwards and rightwards by the fixed connection structure to prevent the drill rod from opening when being clamped. The screw driving mechanism can be directly driven by a hydraulic motor or a motor to drive the screw rod to move up and down, and then the clamping block is driven by the connecting rod mechanism to move left and right, so that the clamping and loosening of the function are realized.
