Description

Technical Field

[0001] The present invention relates to the technical field of shield construction, and more particularly to a self - moving construction platform for lower - part anchor bolts of a shield machine. Background Art

[0002] Shield construction has a circular cross - section. Affected by the shield technology, the upper - middle part anchor bolts and cable bolts can be constructed on the first and second platforms. For the lower - part left and right sides, a total of 4 anchor bolts in each row need to be constructed lagging behind at the tail section of the second - stage conveyor belt of the shield machine. Because there are safety hazards in the operation of the conveyor belt, the lower - part anchor bolts can only be arranged for construction during the early - shift maintenance period, resulting in a serious lag in the support of the lower - part anchor bolts. While restricting production, it is also easy to cause the surrounding rock to be exposed for a long time, which is not conducive to the treatment of the surrounding rock. Using the movable tail of the conveyor belt as a bearing, a self - moving construction platform for lower - part anchor bolts of the shield machine is installed and fabricated. When the conveyor belt of the construction platform is running, the lower - part anchor bolts can also be driven.

[0003] Currently, there are still some problems with the existing self - moving construction platforms for lower - part anchor bolts of shield machines: it is not convenient to adjust the position after the anchor - bolt machine is fixed, so it is not convenient for the anchor - bolt machine to work at different positions. At the same time, it is not convenient for the anchor - bolt machine to drive anchor bolts on both sides without disassembly. When it is necessary to drive anchor bolts on both sides, the anchor - bolt machine needs to be disassembled and then reinstalled, increasing the workload. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a self - moving construction platform for lower - part anchor bolts of a shield machine.

[0005] The embodiment of the present invention provides a self - moving construction platform for lower - part anchor bolts of a shield machine, including two groups of guide rails. The upper surfaces of the two groups of guide rails are both provided with first sliding seats, and the first sliding seats are slidably clamped on the guide rails. A support frame is welded between the upper surfaces of the two groups of guide rails. On both sides of the upper surface of the support frame, support rods are symmetrically welded. At the top of the support rods, a placement plate is welded. Inside the placement plate, a support rod is connected through a fixing mechanism. A sliding cavity is opened at the middle position of the upper surface of the support frame. A sliding plate is welded at the middle position of the sliding cavity. A second sliding seat is slidably arranged on the sliding plate, and the bottom of the second sliding seat is fixedly connected to the sliding plate through a locking component. A first column is welded on the upper surface of the second sliding seat. A rotating seat is welded at the top of the first column. An articulated block is rotatably connected to the rotating seat. On one side of the articulated block, there is an anchor - bolt machine body. One end of the anchor - bolt machine body is fixedly provided with a trunnion, and the trunnion is hinged to the articulated block through a pin shaft. The other end of the anchor - bolt machine body is arranged above the support rod.

[0006] In the above implementation process, by sliding the first sliding seat on the guide rail, it is convenient to adjust the sliding position of the support frame, so as to facilitate the movement of the fixed bolt drilling machine body and facilitate the operation of driving bolts at different positions. By setting the fixing mechanism, it is convenient to fix the end of the support rod supporting the bolt drilling machine body, increasing the stability of the support rod, reducing the situation of falling off, and increasing the safety when supporting the bolt drilling machine body. By setting the rotating seat, trunnion, pin shaft and hinge block, by raising one end of the bolt drilling machine body and then rotating the bolt drilling machine body, the bolt drilling machine body drives the hinge block to rotate, so as to conveniently rotate the bolt drilling machine body from one support rod to the other support rod, thus facilitating the operation of both sides of the bolt drilling machine body without disassembly.

[0007] In a specific implementation scheme, mounting plates are welded to both ends of the guide rail, and mounting positioning holes No. 1 are symmetrically opened on the mounting plates.

[0008] In the above implementation process, it is convenient to install and fix the guide rail.

[0009] In a specific implementation scheme, a roller is rotatably arranged inside the first sliding seat, and the roller contacts the upper surface of the guide rail.

[0010] In the above implementation process, it is convenient for the first sliding seat to slide on the guide rail, reducing the friction force.

[0011] In a specific implementation scheme, a first tightening bolt is threadedly connected to the outer surface of the first sliding seat, and the other end of the first tightening bolt contacts the outer surface of the guide rail.

[0012] In the above implementation process, it is convenient to increase the stability of the first sliding seat after moving.

[0013] In a specific implementation scheme, the fixing mechanism includes a fixing hole, a fixing rod, a spring, a spring groove and a pull ring. The fixing hole is opened on the outer side of the end of the support rod. The fixing rod is slidably arranged on the placing plate. One end of the fixing rod is inserted into the fixing hole. The pull ring is welded to the other end of the fixing rod. The spring groove is opened inside the placing plate. The spring is sleeved on the circumference of the fixing rod.

[0014] In the above implementation process, by pulling the pull ring, after the support rod is placed on the placing plate, releasing the pull ring, and using the elastic force of the spring, the fixing rod is inserted into the fixing hole, so as to conveniently fix the support rod.

[0015] In a specific implementation scheme, one end of the spring is arranged on the inner wall of the spring groove, and the other end of the spring is fixedly arranged on the fixing rod.

[0016] During the above implementation process, it is convenient to apply the elastic force of the spring to the fixed rod.

[0017] In a specific implementation, the locking assembly includes a fastening bolt, a nut, a first gasket, and a second gasket. The fastening bolt is threadedly connected to the bottom of the second sliding seat, the nut is threadedly connected to the other end of the fastening bolt, the first gasket is disposed between the end of the fastening bolt and the second sliding seat, and the second gasket is disposed between the nut and the second sliding seat.

[0018] During the above implementation process, by threadedly connecting the fastening bolt and the nut, it is possible to lock both sides of the bottom of the second sliding seat, thereby conveniently increasing the friction between the second sliding seat and the sliding plate and increasing the installation stability.

[0019] In a specific implementation, a rotation groove is formed inside the rotating seat. A rotating block is welded to the bottom of the hinge block, and the rotating block is rotatably disposed in the rotation groove. Two groups of positioning holes are formed at both ends of the rotating block, and a second tightening bolt is threadedly connected to the outer surface of the rotating seat, and the second tightening bolt is threadedly connected to the positioning holes.

[0020] During the above implementation process, by rotating the rotating block inside the rotation groove, the second tightening bolt is selected from one group of positioning holes into the other group of positioning holes, thereby completing a 180-degree rotation of the rotating block, which conveniently rotates the hinge block by 180 degrees, and thus conveniently rotates the anchor machine body from one side to the other side to complete the position swapping.

[0021] In a specific implementation, the two groups of positioning holes are arranged at an included angle of 180°.

[0022] During the above implementation process, a 180-degree rotation can be conveniently performed.

[0023] In a specific implementation, two groups of guardrails are symmetrically welded to both sides of the upper surface of the support frame.

[0024] During the above implementation process, the safety during use can be increased.

[0025] Beneficial effects:

[0026] 1. By sliding the first sliding seat on the guide rail, it is convenient to adjust the sliding position of the support frame, thereby conveniently moving the fixed anchor machine body and facilitating the operation of driving anchor bolts at different positions;

[0027] 2. By providing a fixing mechanism, it is convenient to fix the end of the support rod supporting the anchor machine body, increasing the stability of the support rod, reducing the situation of falling off, and increasing the safety when supporting the anchor machine body;

[0028] 3. By setting the rotating seat, trunnion, pin shaft and hinge block, one end of the bolt drilling machine body is lifted, and then the bolt drilling machine body is rotated, so that the bolt drilling machine body drives the hinge block to rotate, thereby facilitating the rotation of the bolt drilling machine body from the support rod on one side to the support rod on the other side, and thus facilitating the completion of the two-sided work of the bolt drilling machine body without disassembly.
