Description

Technical Field

[0001] The utility model relates to an automatic rod feeding device, in particular to an anti-stuck automatic rod feeding device suitable for segmented anchor rods. Background Art

[0002] The segmented anchor is a support device used in geotechnical engineering, mainly composed of anchor segments, anchor joints, anchor anchor ends and anchor sleeves. Traditional automatic rod delivery devices are often only suitable for single-segment anchors of shorter lengths. When delivering segmented anchors, the diameter of the anchor sleeve is often larger than the diameter of the anchor, which will cause the delivery wheel to idle or get stuck, affecting the delivery efficiency. In addition, during the stuck process, the delivery wheel will squeeze the anchor sleeve, which can easily cause the anchor sleeve to deform and lead to material waste. Utility Model Content

[0015] When this embodiment is implemented, the segmented anchor rod is first fixed to the gripper, and the overall length of the anti-stuck rod itself is changed by the extension and retraction of the secondary telescopic rod in the rod barrel of the main support rod. The first auxiliary arm and the second auxiliary arm are squeezed or relaxed by the change in the length of the anti-stuck rod, thereby changing the distance between the first auxiliary arm and the second auxiliary arm, and then changing the distance between the first transmission wheel and the second transmission wheel, until the distance between the transmission surfaces of the first transmission wheel and the second transmission wheel is adjusted to be equal to the diameter of the first segment of the segmented anchor rod; the operator pushes the first segment of the anchor rod between the first transmission wheel and the second transmission wheel; when it is pushed to the first transmission wheel After the delivery wheel and the second transmission wheel contact the first section of the anchor rod, the gear teeth of the first transmission wheel and the second transmission wheel clamp the first section of the anchor rod, and the transmission force applied by the rotation of the first transmission wheel and the second transmission wheel pushes the first section of the anchor rod forward; when the first transmission wheel and the second transfer wheel are pushed to contact the anchor rod connecting sleeve of the first section of the anchor rod and the second section of the anchor rod, the length of the anti-stuck rod itself is increased by the elongation of the secondary telescopic rod in the rod barrel of the main support rod, and the anti-stuck rod with increased length squeezes the first auxiliary arm and the second auxiliary arm, thereby increasing the distance between the first auxiliary arm and the second auxiliary arm, and then increasing the distance between the first transmission wheel and the second transmission wheel. , adjust until the distance between the transmission surfaces of the first transmission wheel and the second transmission wheel is equal to the diameter of the anchor rod connecting sleeve, the gear teeth of the first transmission wheel and the second transmission wheel clamp the anchor rod connecting sleeve, and the transmission force applied by the rotation of the first transmission wheel and the second transmission wheel pushes the anchor rod connecting sleeve, so that the anchor rod connecting sleeve can smoothly pass through the first transmission wheel and the second transmission wheel, avoiding the situation that the gear teeth of the first transmission wheel and the second transmission wheel are stuck or idling.

[0020] The advantage of this solution is that during the rod segment transportation process, the conveying surface with anti-slip grooves has a strong match with the threaded steel bars and anchor rods, which can enhance the friction and transmission force between the pulley and the anchor rod, and can effectively prevent the anchor rod from slipping or sliding on the pulley, so that the pulley can be firmly fixed between the first conveying wheel and the second conveying wheel and maintain a stable rate to convey the anchor rod.

[0021] As a further solution of the present utility model, elastic rings are provided on the upper and lower wheel pieces of the first transmission wheel and the wheel pieces on the upper and lower sides of the transmission surface of the second transmission wheel.

[0023] As a further solution of the utility model, the first auxiliary wall and the second auxiliary wall are symmetrically arranged.

[0024] The advantage of this solution is that the first auxiliary wall and the second auxiliary wall have a left-right symmetrical structure, so that the first transmission wheel installed on the first auxiliary arm and the second transmission wheel installed on the second auxiliary arm are also symmetrical structures; the symmetrical structure can maintain the stability of the first transmission wheel and the second transmission wheel, so that the first transmission wheel and the second transmission wheel can be transmitted in a balanced manner, so that the stress on the left and right sides of the anchor rod is the same during the transmission process and can be transmitted in a straight line, avoiding the deviation, shaking or jamming of the anchor rod due to uneven force.

[0043] During implementation, the operator holds the segmented anchor rod and passes the segmented anchor rod through the two grippers 6, and changes the overall length of the anti-stuck rod 1 by extending and retracting the secondary telescopic rod in the rod barrel of the main support rod, and squeezes or relaxes the first auxiliary arm 2 and the second auxiliary arm 3 by changing the length of the anti-stuck rod 1, thereby changing the distance between the first auxiliary arm 2 and the second auxiliary arm 3, and further changing the distance between the first transmission wheel and the second transmission wheel, until the distance between the transmission surfaces of the first transmission wheel and the second transmission wheel is adjusted to be equal to the diameter of the first segment of the segmented anchor rod;
