Description

Technical Field

[0001] This utility model relates to the field of underground construction, specifically to a construction frame for driving anchor bolts at the top of an underground well. Background Technology

[0002] Anchor bolt installation in underground mines typically occurs in complex environments such as coal mines, metallurgical mines, underground engineering projects, and tunnel projects. Traditional methods often require workers to use scaffolding or temporary platforms to install the anchor bolts. However, this method has many drawbacks, such as time-consuming and labor-intensive scaffolding installation, poor platform stability, and high difficulty for workers.

[0003] Existing high-stability construction scaffolds may not have fully considered changes in ground flatness during the design process, making it difficult to adjust them according to ground conditions during actual use, thus affecting construction efficiency and safety. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a construction frame for driving anchor bolts at the top of a well.

[0005] This utility model is achieved through the following technical solution:

[0006] A construction frame for drilling anchor bolts at the top of a well includes a support platform. Four leveling components are installed around the bottom of the support platform to adjust its height. Each leveling component includes a cylinder and a telescopic rod. The outer surface of the telescopic rod is threaded, and a driven gear is threadedly connected to its upper part. A driving gear meshes with one side of the driven gear. A rotating shaft extending to the cylinder is fixed at the center of the driving gear, and a rocker arm is connected to its end. A compass level is installed on the top of the support platform, and a liftable transfer trolley is installed at the bottom. A scale is installed on the outside of the telescopic rod.

[0007] Alternatively, universal joints can be connected between the telescopic rod and the support platform.

[0008] Alternatively, the transfer trolley includes a base plate, which is connected and fixed to the bottom of the support platform via a scissor arm. Multiple wheels are provided on the lower part of the base plate, and a lead screw is rotatably supported in the scissor arm, with one end of the lead screw connected to a drive motor.

[0009] Alternatively, a limiting slot may be provided on the top of the support platform.

[0010] Alternatively, a protective frame may be installed on the upper part of the support platform.

[0011] Alternatively, a supporting staircase may be fixedly installed on one side of the supporting platform.

[0012] Alternatively, spacers may be evenly distributed on the lower part of the cylinder block.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This type of construction frame for anchor bolt installation at the top of the well enhances the overall stability of the construction frame by setting a leveling component. The entire support frame is placed in the anchor bolt installation area in the well, and the initial leveling state of the construction frame is checked by using a compass level to ensure that it is in a relatively horizontal position before adjustment. According to the flatness of the ground, the driven gear and the driving gear are rotated by rotating the rocker arm, which in turn drives the telescopic rod to extend and retract within the support column to adjust the height of the construction frame. The changes in the scale on the ruler are observed to precisely control the extension and retraction length of the telescopic rod, ensuring that the construction frame reaches the required height and a stable state, making the construction frame more firmly attached to the uneven ground. The leveling state of the construction frame is checked again by using a compass level to ensure that it is in a completely horizontal position after adjustment, ensuring the stability and safety of the construction process.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0021] like Figure 1 , 2As shown in Figures 3, 4, and 5, a construction frame for drilling anchor bolts at the top of a well includes a support platform 1. Four leveling components are installed around the bottom of the support platform 1 to adjust its balance according to different environments. Each leveling component includes a cylinder 2 and a telescopic rod 3. The telescopic rod 3 has threads on its outer surface and a driven gear 4 is threaded onto its upper part. A driving gear 5 meshes with one side of the driven gear 4. A rotating shaft extending to the cylinder 2 is fixedly connected to the center of the driving gear 5, and a rocker arm 6 is connected to its end. A compass level 7 is installed on the top of the support platform 1, and a lifting and lowering transport trolley 8 is installed at the bottom. A scale 9 is installed on the outside of the telescopic rod 3.

[0022] like Figure 1 , 2 As shown, universal joints 10 are connected between the telescopic rod 3 and the support platform 1.

[0023] like Figure 1 , 2 As shown in Figure 5, the transfer trolley 8 includes a base plate 11, which is connected and fixed to the bottom of the support platform 1 via a scissor arm 12. Multiple wheels are provided on the lower part of the base plate 11. A lead screw 13 is rotatably supported in the scissor arm 12, and one end of the lead screw 13 is connected to a drive motor 14.

[0024] like Figure 1 As shown, a limiting groove 15 is provided on the top of the support platform 1.

[0025] like Figure 1 , 2 As shown, a protective frame 16 is installed on the upper part of the support platform 1.

[0026] like Figure 1 , 2 As shown, a supporting staircase 17 is fixedly installed on one side of the supporting platform 1.

[0027] like Figure 1 , 2 As shown, pads 18 are evenly distributed on the lower part of the cylinder body 2.

[0028] The implementation principle of a construction frame for driving anchor bolts at the top of a well in this application embodiment is as follows:

[0029] When driving the top of the well to install anchor bolts, the support frame 1 is first placed in the anchor bolt area of ​​the well using the transfer trolley 8. Then, the drive motor 14 is started to drive the screw 13 to rotate. During the rotation of the screw 13, the scissor arm 12 will retract, so that the construction frame is placed on the ground and the pad 18 is in contact with the ground.

[0030] Due to the uneven surface of the mine, the compass level 7 will indicate that the support platform 1 is tilted. Adjustment is necessary to prevent personnel from slipping on the support platform 1. During adjustment, rotating the rocker arm 6 drives the drive gear 5 and driven gear 4. The rotation of the driven gear 4 causes the telescopic rod 3 to extend and retract from the cylinder 2. As the telescopic rod 3 moves vertically upwards from the cylinder 2, the universal joint 10 allows for adaptive adjustment of the angle and position of other telescopic rods 3 connected to the support platform 1. This prevents the movement of one telescopic rod 3 from causing undue pulling or compression of other telescopic rods 3, effectively preventing jamming. In case of an accident, when adjusting the height of the construction frame, observe the changes in the scale on the ruler 10, and precisely control the extension length of the telescopic rod 3 to ensure that the construction frame reaches the required height and is stable, so that the construction frame fits more firmly against the uneven ground. Use the compass level 9 again to check the level of the construction frame to ensure that it is in a completely level position after adjustment, and ensure the stability and safety during the construction process. After the adjustment is completed, the workers climb the support ladder 12 to the top of the support frame 1 to carry out construction work. The top of the support frame 1 is equipped with a protective frame 11, which provides an additional protective layer for the construction workers and reduces the risk of injury caused by accidental falls when working at the top of the well.

[0031] When anchoring another area, the rocker arm 6 is rotated to retract the telescopic rod 3 into the cylinder 2. At the same time, the drive motor 14 is started to rotate the lead screw 13, thereby extending the scissor arm 12. After the scissor arm 12 is extended, the wheels of the transfer trolley 8 will contact the ground and lift the support platform 1. At this time, the pad block 18 will move away from the ground to prevent collision when pushing the transfer trolley 8.

[0032] Then move the construction scaffold to another area where anchor bolts need to be installed, and continue the construction work according to the above steps.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
