Description

Technical Field

[0001] The utility model relates to the technical field of rod-changing grippers, in particular to a rod-changing gripper assembly for an anchor-casting trolley. Background Art

[0002] The anchor grouting trolley is an anchor trolley used in tunnels that integrates drilling, anchor installation, and grouting. Anchor installation is a key part of the work of the anchor grouting machine. Before installation, the anchors need to be grabbed from the anchor warehouse to the anchor installation position. Therefore, a fast and accurate anchor grabbing mechanism is required. This patent is designed to solve this problem.

[0003] An anchor grouting trolley consists of a gripper, a fixing device, a blocking device, and a drive device. Currently, most grippers on anchor grouting trolleys use a mechanical rigid connection to grasp the anchor rod, which has many joints and a complex structure. Some also use springs and other structures to grasp the anchor rod, but the grasping effect is not ideal.

[0004] While many products boast comprehensive design features, they often fall short in practical applications, particularly when it comes to accurately and quickly grasping anchor bolts. This often results in issues like difficulty grasping or inaccurate gripping. This hinders the effectiveness and widespread adoption of anchor-injection machines, preventing their widespread application in tunnel construction. Utility Model Content

The blocks 15 are installed together to realize that the rod-changing cylinder 7 rotates along with the rotation of the rotating block 15. The output end of the rod-changing cylinder 7 is fixedly connected to a rotating clamping ring 12, and the rotating clamping ring 12 can be driven to rotate by the rod-changing cylinder 7. The rotating clamping ring 12 is internally rotatably connected to the rod-changing shaft 3. The rotating connection between the rotating clamping ring 12 and the rod-changing shaft 3 can prevent the rod-changing grab arm 2 from getting stuck and unable to swing normally. The outer wall of the rod-changing shaft 3 is fixedly connected to the rod-changing grab arm 2. By fixing the rod-changing grab arm 2 to the outer wall of the rod-changing shaft 3, a limited position component is arranged inside the rod-changing bracket 1. The limited position component is used to limit the rotation range of the rod-changing grab arm 2. The rod-changing grab arm 2 is internally rotatably connected to the rod-changing The second shaft 5 can realize the rotation of the rod-changing grab arm 2 by rotating it on the outer wall of the rod-changing shaft 2 5, so that the swing of the rod-changing grab arm 2 can be realized by the cooperation of other shafts, and the outer wall of the rod-changing shaft 2 5 is fixedly connected to the inside of the rod-changing bracket 1; the limiting assembly includes a limiting plate 10, the outer wall of the limiting plate 10 is fixedly connected to a fixing rod 18, one end of the fixing rod 18 is fixedly connected to a fixing plate three 17, the outer wall of the fixing plate three 17 is fixedly connected to the inside of the rod-changing bracket 1, and the limiting plate 10 can be fixed to the inside of the rod-changing bracket 1 by the cooperation of the fixing rod 18 and the fixing plate three 17, and the inside of the rod-changing grab arm 2 is fixedly connected to a partition one 11, which is separated by The obstruction of plate 11 can prevent the rod-changing grab arm 2 from swinging excessively; the outer wall of the rod-changing shaft 3 is fixedly connected to a retaining ring 9, and the outer wall of the retaining ring 9 is set on the outer wall of the rod-changing grab arm 2. By setting the retaining ring 9 slightly larger than the shaft, the axial movement of the fixed parts can be achieved; the outer wall of the rod-changing cylinder 7 is set inside the rod-changing grab arm 2, and the outer wall of the rotating block 15 is set inside the rod-changing bracket 1; the inside of the rod-changing grab arm 2 is fixedly connected to partition plate 2 14, and the external factors to which the device is subjected can be reduced by partition plate 2 14; the outer wall of the rod-changing bracket 1 is fixedly connected to a connecting plate 19, and by connecting the connecting plate 19 and the rod-changing bracket 1 together, the rod-changing device and the anchor grouting trolley can be installed together.

[0025] Reference Figure 1 - Figure 4One end of the rod-changing grasping arm 2 is fixedly connected with a fixing plate 13. By installing the fixing plate 13 at one end of the rod-changing grasping arm 2, conditions are created for subsequent grasping work. An adjusting pad 4 is provided on the inner wall of the fixing plate 13. By installing the adjusting pad 4 on the inner wall of the fixing plate 13, conditions can be created for subsequent adjustment of the magnet 8. The outer wall of the adjusting pad 4 is fixedly connected with a magnet 8. Through the connection between the magnet 8 and the adjusting pad 4, when it is necessary to fix anchor rods of different sizes, the position of the magnet 8 can be adjusted by adjusting the pad 4 to adapt to anchor rods of different sizes; the magnet 8 is provided on the inner walls on both sides of the fixing plate 13. By providing two rows of magnets 8, the anchor rod can be grasped by the magnetic force of the magnet 8. The magnet 8 is provided at one end of the rod-changing grasping arm 2.

[0026] Working principle: The rod-changing grab arm 2 is internally connected to the rod-changing shaft 1 3 and the rod-changing shaft 2 5. When the rod-changing oil cylinder 7 drives the rotating clamping ring 12 to rotate the rod-changing shaft 1 3, the rotating clamping ring 12 will squeeze the rod-changing shaft 1 3. The rotating clamping ring 12 is rotatably connected to the outer wall of the rod-changing shaft 1 3. Because the rod-changing oil cylinder 7 and the rotating block 15 are installed together, and the rotating block 15 is connected to the outer wall of the rod-changing shaft 3 6, when the rotating clamping ring 12 rotates due to extrusion, the rod-changing oil cylinder 7 will rotate with the rotation of the rotating block 15. Through the cooperation of the rod-changing shaft 1 3 and the rod-changing shaft 2 5, the rod-changing grab arm 2 can be swung around the hinge point. When the rod-changing grab arm 2 rotates, its grasping position can be close to the anchor rod. By installing the fixing plate 13 on the upper end of the rod-changing grab arm 2, conditions can be created for subsequent grasping. An adjusting pad 4 is installed in the fixing plate 13. The outer wall of the adjusting pad 4 is equipped with a magnet 8. By using the adjusting pad 4, the magnet 8 can be adjusted so that the magnet 8 can adapt to anchor rods of different sizes and grasp them. When the rod-changing cylinder 7 drives the rod-changing grasping arm 2 to swing, a certain gap is left between the magnet 8 and the anchor rod. The anchor rod can be sucked into the middle of the two rows of magnets 8 by the magnetic force of the magnet 8. The anchor rod can be tightly grasped in the groove by the suction force of the two rows of magnets 8. When the rod-changing grasping arm 2 is rotated to the position required by the anchor rod, the rod-changing grasping arm 2 can be blocked by a combination of machine limiting structures such as the limiting plate 10 to prevent it from swinging excessively. The connecting plate 19 can be installed on the anchor grouting trolley by fixing devices such as bolts. The two connecting plates 19 and the rod-changing bracket 1 are connected together, so that the entire grasping device can be installed on the anchor grouting trolley to allow it to work normally.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
