Description

Technical Field

[0001] The present invention relates to the technical field of mine steel corridors, and in particular to an open-pit mine slope steel corridor portal frame and an installation and construction method thereof. Background Art

[0002] Open-pit mines have complex slopes and large elevation differences. Overhead steel corridors can overcome obstacles such as broken slopes and deep trenches, safely and efficiently connecting various working areas in the mine. This ensures stable transportation of personnel and materials, while preventing surface transportation from being affected by slope collapse and undulating terrain. Steel corridors are primarily secured in two ways: overhead and floor-mounted. Floor-mounted steel corridors consist of a steel corridor gantry, connected to it by tie rods and supports. In a flat installation scenario, the steel corridor gantry can be transported directly to the designated location and then installed using lifting machinery, making the entire process relatively convenient.

[0003] However, currently, steel gallery gantry installations must be performed on steep slopes, especially when the slope is greater than 8°, which presents significant challenges. Since steel gallery gantry widths are typically around 5 meters, using crawler transport machinery for reverse transportation would not only be difficult to secure effectively, but would also significantly reduce transportation efficiency. More critically, steep slopes often lack dedicated lifting platforms, preventing the proper operation of lifting machinery. Furthermore, if the slope is composed of hard rock, creating a suitable platform for lifting operations requires significant effort. Summary of the Invention

[0035] Example

[0036] like Figures 1 to 7 As shown, the present invention proposes a steel corridor portal frame for the slope of an open-pit mine, including a transverse support frame 2, with corresponding vertical support frames 1 provided at both ends of the transverse support frame 2. When the transverse support frame 2 is installed in the middle of a pair of vertical support frames 1, in order to ensure that the grooves at both ends of the transverse support frame 2 are inserted into the limiting slots 17, it is necessary to swing the vertical support frame 1 after installation to ensure that the spacing between the pair of vertical support frames 1 becomes larger, thereby facilitating the installation of the transverse support frame 2. A rubber sleeve 12 is fixedly connected to the interior of the vertical support frame 1. The rubber sleeve 12 is fixed to the interior of the vertical support frame 1 and is sealed with the output shaft of the motor 11 to enhance the sealing performance of the device. A limiting card 172 is fixedly connected to the top of the vertical support frame 1 to clamp the end of the transverse support frame 2. The limiting card 172 is fixed to the top of the vertical support frame 1, clamps the end of the transverse support frame 2, and limits the upward movement of the transverse support frame 2.

[0037] Among them, Figures 1 to 7 As shown, the mounting base plate 3 is also provided with a plurality of seventh bolt holes 34. The seventh bolt holes 34 are provided on the mounting base plate 3, and the mounting base plate 3 is fixed to the slope foundation by bolts. The rubber sleeve 12 is sealed and sleeved with the output shaft of the motor 11. The bottom end of the vertical support frame 1 is rotatably connected to the mounting base plate 3. The mounting base plate 3 is rotatably connected to the bottom end of the vertical support frame 1 and fixed to the slope foundation by bolts, providing bottom support for the entire steel corridor. The vertical support frame 1 is provided with a limit card slot 17. The limit card slot 17 is provided on the vertical support frame 1 and is connected to the interior. The grooves at the two ends of the horizontal support frame 2 are inserted into the grooves, which limit the horizontal support frame 2. The limit card slot 17 is connected to the interior of the vertical support frame 1. The two ends of the horizontal support frame 2 are provided with grooves for clamping the limit card slot 17. The lifting mechanism is used to drive the corresponding end of the horizontal support frame 2 to move up and down.

[0038] Secondly, if Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the upper surface of the mounting base 3 is provided with a locking mechanism for fixing the vertical support frame 1. The locking mechanism includes an inclined support plate 18 fixedly connected to the bottom outer wall of the vertical support frame 1. The inclined support plate 18 is fixed to the bottom outer wall of the vertical support frame 1, and the bottom end is connected to an insert block 181, which assists in fixing the vertical support frame 1 and ensures its stable installation. A pair of insert blocks 181 are fixedly connected to the bottom end of the inclined support plate 18. The insert blocks 181 are connected to the bottom end of the inclined support plate 18 and can be inserted into the locking groove 35 to achieve the angle locking of the vertical support frame 1 through bolt fixation. The insert blocks 181 are each provided with a third bolt hole 182. The upper surface of the mounting base 3 is fixedly connected to a backing plate 31. The backing plate 31 is fixed to the upper surface of the mounting base 3 and has a rotation groove 32 and a locking groove 35 to assist in the rotation and angle locking of the vertical support frame 1. The backing plate 31 is provided with a pair of locking slots 35 for inserting the insert blocks 181. The locking slots 35 are provided on the backing plate 31 for inserting the insert blocks 181, thereby achieving angular locking of the vertical support frame 1. Each locking slot 35 has a sixth bolt hole 36 coaxially located with the corresponding third bolt hole 182. The sixth bolt hole 36 is provided within the locking slot 35 and corresponds to the third bolt hole 182 on the insert blocks 181. Bolts secure the insert blocks 181 to the locking slots 35.

[0039] In addition, if Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, a pair of rotation slots 32 are defined at one end of the backing plate 31, distal from the locking slot 35. These slots 32 are formed on the backing plate 31 and contain fixed shafts 33, which engage the rotation blocks 19 and provide space for the vertical support frame 1 to rotate. Each of the rotation slots 32 is fixedly connected to a shaft 33, which is secured within the slots 32 and flexibly engages with the rotation blocks 19, serving as the axis of rotation for the vertical support frame 1. The bottom end of the vertical support frame 1 is fixedly connected to a rotation block 19, which engages within the corresponding rotation slot 32 and flexibly engages with the corresponding shaft 33.

[0040] It is worth noting that if Figures 4 to 7As shown, the lifting mechanism of the internal synchronous switch of the vertical support frame 1 and the limit card slot 17 includes a motor 11 fixedly connected to the inner bottom wall of the vertical support frame 1. The motor 11 is fixed to the inner bottom wall of the vertical support frame 1, and the output shaft drives the screw rod 16 to rotate, providing power for the lifting mechanism. The output shaft of the motor 11 is fixedly connected to the screw rod 16. The top end of the screw rod 16 is connected to the inside of the vertical support frame 1 for rotation. It is driven by the motor 11 to rotate and drive the spiral clamp 13 to slide. The top end of the screw rod 16 is connected to the inside of the vertical support frame 1 for rotation. The inside of the vertical support frame 1 is connected to the spiral clamp 13 that is spirally sleeved with the screw rod 16 for sliding. The spiral clamp 13 slides inside the vertical support frame 1 and is spirally sleeved with the screw rod 16. It is driven by the screw rod 16 to drive the U-shaped clamp 14 to move. A U-shaped clamping block 14 is fixedly connected to the spiral clamping plate 13 and is clamped into the limiting clamping groove 17. The U-shaped clamping block 14 is connected to the spiral clamping plate 13 and is clamped into the limiting clamping groove 17. It fixes the end of the horizontal support frame 2 by cooperating with the positioning plate 21.

[0041] Further, if Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the transverse support frame 2 and the vertical support frame 1 are provided with a connecting mechanism for fixedly connecting the transverse support frame 2 and the vertical support frame 1. The connecting mechanism includes a pair of second bolt holes 171 defined at the top of the retaining slot 17. The second bolt holes 171 are defined at the top of the retaining slot 17 and correspond to the fifth bolt holes 23 on the transverse support frame 2, securing the transverse support frame 2 to the vertical support frame 1 via bolts. Multiple pairs of fifth bolt holes 23 corresponding to the second bolt holes 171 are defined at each end of the transverse support frame 2. The fifth bolt holes 23 are defined at each end of the transverse support frame 2 and correspond to the second bolt holes 171 at the top of the retaining slot 17, securing the transverse support frame 2 to the vertical support frame 1 via bolts. The connecting mechanism also includes multiple pairs of positioning plates 21 fixedly connected to the ends of the transverse support frame 2. Each positioning plate 21 has a fourth bolt hole 22 defined therein for retaining the end of the U-shaped clamp 14. The fourth bolt hole 22 is defined on the positioning plate 21 and corresponds to the first bolt hole 15 on the U-shaped clamp 14, securing the two together via bolts. Both ends of the U-shaped clamp block 14 are provided with first bolt holes 15 corresponding to and overlapping with the positioning plate 21. The first bolt holes 15 are provided at both ends of the U-shaped clamp block 14 and correspond to and overlap with the fourth bolt holes 22 on the positioning plate 21, and the two are fixed by bolts.

[0042] This application provides an installation and construction method for a steel gallery gantry on an open pit slope, such as Figure 1 - Figure 7 As shown, the following steps are included:

[0043] S1, fix the installation base plate to the slope foundation with bolts through the seventh bolt hole 34 of the installation base plate 3;

[0044] S2. Adjust the angle of the vertical support frame and lock it. Push the vertical support frame 1 to rotate around the rotating block 19 and the shaft 33. Drive the oblique support plate 18 so that the insert block 181 is inserted into the locking groove 35. Align the third bolt hole 182 with the sixth bolt hole 36 to secure it. Ensure that the distance between the pair of vertical support frames 1 is adapted to the horizontal support frame 2.

[0045] S3, install the horizontal support frame to the vertical support frame, and insert the grooves at both ends of the horizontal support frame 2 into the limit slots 17 of the vertical support frame 1;

[0046] S4. Drive the lifting mechanism to connect the horizontal support frame and the U-shaped clamping block, start the motor 11, and drive the U-shaped clamping block 14 to move via the screw rod 16 and the screw clamping plate 13, so that the positioning plate 21 overlaps with the U-shaped clamping block 14, aligning the first bolt hole 15 with the fourth bolt hole 22 to fix it;

[0047] S5. Fix the horizontal support frame and the vertical support frame. The horizontal support frame 2 moves upward to abut against the limiting clamping plate 172, aligns the fifth bolt hole 23 with the second bolt hole 171 and is fixed to achieve a rigid connection with the vertical support frame 1.

[0048] In this embodiment, when using the open-pit mine slope steel corridor portal frame, the seventh bolt hole 34 on the installation base plate 3 is first fixed to the slope foundation using multiple bolts. The vertical support frame 1 can then be manually pushed to rotate upward with the rotating block 19 clamping the shaft 33 in the rotating groove 32 as the center. The vertical support frame 1 then drives the diagonal support plate 18 to rotate until the insert block 181 at the end of the diagonal support plate 18 is inserted into the locking groove 35 of the pad 31. The third bolt hole 182 on the insert block 181 is aligned with the sixth bolt hole 36 in the locking groove 35 and fixed by bolts, thereby completing the angular locking of the pair of vertical support frames 1. At this time, it is necessary to ensure that the distance between the pair of vertical support frames 1 is sufficient for the subsequent installation of the horizontal support frame 2.

[0049] Then, insert the grooves at both ends of the horizontal support frame 2 into the limiting grooves 17 of the vertical support frame 1. Then, the motors 11 in the pair of vertical support frames 1 can be started synchronously. When the pair of motors 11 are turned on synchronously, their output shafts drive the screw rod 16 to rotate, and the spiral clamping plate 13, which is spirally sleeved with the screw rod 16, slides inside the vertical support frame 1, and at the same time drives the U-shaped clamping block 14 to move synchronously in the limiting grooves 17. Before this, when the two ends of the horizontal support frame 2 are inserted into the limiting grooves 17, the positioning plates 21 at both ends of the horizontal support frame 2 will overlap and connect with the two ends of the U-shaped clamping block 14, and the first bolt holes 15 at both ends of the U-shaped clamping block 14 will be aligned with the fourth bolt holes 22 on the positioning plates 21, and then fixed with bolts, the two ends of the horizontal support frame 2 can be fixedly connected with the corresponding ends of the U-shaped clamping block 14. Finally, when the horizontal support frame 2 moves upward to abut against the limiting clamp 172, each pair of fifth bolt holes 23 on each end of the horizontal support frame 2 aligns with the corresponding second bolt holes 171, and then is fastened with bolts, thereby achieving a rigid connection between the ends of the horizontal support frame 2 and the vertical support frame 1, which is quick and labor-saving. The rubber sleeve 12 is sealed and sleeved with the output shaft of the motor 11, enhancing the sealing performance of the device.
