[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.
[0026] The mounting bracket of the embodiment of the present invention includes a first pipe fitting 1, a mounting assembly 2 and a lifting assembly 3. The first pipe fitting 1 is adapted to be mounted on a tower (not shown in the figure), and one end of the first pipe fitting 1 extends out of the tower. The mounting assembly 2 includes a first mounting support 21 and a mounting member 22. The first mounting support 21 is connected to one end of the first pipe fitting 1, and one end of the mounting member 22 is detachably connected to the end of the first mounting support 21 away from the first pipe fitting 1. The other end of the mounting member 22 is adapted to be connected to a device (not shown in the figure) to fix the device. One end of the lifting assembly 3 is connected to the first pipe fitting 1, and the other end of the lifting assembly 3 is connected to the mounting member 22. At least a part of the lifting assembly 3 is movable up and down relative to the first pipe fitting 1 to drive the mounting member 22 to move in the up and down direction.
[0027] Specifically, as Figure 1 shown, the first pipe fitting 1 is mounted on the top of the tower, or the first pipe fitting 1 is mounted on the side of the tower. The right end of the first pipe fitting 1 extends out of the tower. The first mounting support 21 is mounted on the right end of the first pipe fitting 1. The upper end of the mounting member 22 is detachably connected to the lower end of the first mounting support 21. The lower end of the mounting member 22 is used for fixedly connecting to the device. The lifting assembly 3 is mounted on the first pipe fitting 1. The lifting assembly 3 is used to drive the mounting member 22 to move up and down, thereby driving the device to move in the up and down direction.
[0028] Optionally, the connection between the first pipe fitting 1 and the tower is a detachable connection, which is convenient for the installation and disassembly of the mounting bracket. The distance that the right end of the first pipe fitting 1 extends out of the tower can be determined according to the size of the device and the requirements of the installation position, which is convenient for the installation of the device.
[0029] For example, the device is an automatic coal yard inventory instrument.
[0030] The mounting bracket according to the embodiment of the present invention installs the first pipe fitting 1 on the tower, and installs the first mounting seat 21 at one end of the first pipe fitting 1. By installing the device on the mounting member 22, when the lifting assembly 3 drives the mounting member 22 to move up and down, the device is synchronously driven to move up and down. Since the mounting member 22 and the first mounting seat 21 are detachably connected, through the connection between the mounting member 22 and the first mounting seat 21, it is convenient to fix the device on the first pipe fitting 1, reducing the installation difficulty of the device and having high installation accuracy.
[0031] Furthermore, in this embodiment, by setting the mounting member 22 matching the device and the first mounting seat 21 cooperating with the mounting member 22, the non-standard size connection between the device and the tower is changed into the standard size connection between the device and the mounting member 22 and between the mounting member 22 and the first mounting seat 21, facilitating the connection between the device and the tower and improving the installation accuracy at the same time.
[0032] Furthermore, in this embodiment, through the setting of the mounting member 22, the installation position and installation angle of the device can be adjusted to adapt to the installation requirements of different devices.

The other end of the lifting assembly 3 is connected to the upper end of the mounting plate 221. By pre-fixing the device on the mounting plate 221 on the ground and using the lifting assembly 3 to lift the mounting plate 221, the mounting plate 221 and the connecting plate 222 up to the first mounting seat 21, through the connection between the connecting plate 222 and the first mounting seat 21, it is convenient to connect the device to the tower.
[0036] In some embodiments, the end face of the mounting plate 221 away from the first mounting seat 21 is a plane or an inclined plane.
[0037] Specifically, as Figure 2As shown, the lower end surface of the mounting plate 221 is a flat surface, or the lower end surface of the mounting plate 221 is an inclined surface.

The first support plate 61 is connected to the tower through a U-bolt 7, and the second support plate 62 is connected to the second pipe fitting 5 through a U-bolt 7. Through the arrangement of the third mounting seat 6, it is convenient to fix the second pipe fitting 5 on the tower.
[0057] Optionally, the third mounting seat 6 is connected to the truss angle steel of the tower through a U-bolt 7.
[0058] In some embodiments, there are multiple second pipe fittings 5, and the multiple second pipe fittings 5 are arranged at intervals in the axial direction of the first pipe fitting 1.
[0059] Specifically, as Figure 2 shown, the axial direction of the first pipe fitting 1 is consistent with the left-right direction. There are multiple third mounting seats 6, and the multiple third mounting seats 6 are arranged in one-to-one correspondence with the multiple second pipe fittings 5.

[0062] Optionally, when the second pipe fitting 5 is sleeved on the first pipe fitting 1, the compression screw is screwed into the threaded hole on the second pipe fitting 5 and does not abut against the first pipe fitting 1, that is, the first pipe fitting 1 is rotatable relative to the second pipe fitting 5. After rotating the first pipe fitting 1 to make the device in a vertical state, tighten the compression bolt 8 to fix the first pipe fitting 1.
[0063] Before hoisting the device, first adjust the first pipe fitting 1 to be in a horizontal state. By loosening the compression bolt 8, adjust the positions of the left end and the right end of the third mounting support 6 in the up and down directions to make the first pipe fitting 1 in a horizontal state. After hoisting the device, adjust the device to be in a vertical state. By rotating the first pipe fitting 1 to make the device in a vertical state, tighten the compression bolt 8 to fix the first pipe fitting 1 after adjustment.
[0064] Optionally, when the device needs to be overhauled, separate the first mounting support 21 from the connecting plate 222, and rotate the winding drum to release the rope 32 to move the device to the ground for overhaul.
[0065] The mounting bracket of the embodiment of the present invention can adapt to installing devices with heavier weight and larger volume at high positions of the tower by setting different mounting plates 221. By connecting the device to the mounting plate 221, and the mounting plate 221 is connected to the first mounting support 21 through the connecting plate 222, the device is prevented from being in a suspended state, improving the reliability of the device and facilitating fixing the device on the first pipe fitting 1. And when overhaul is needed, by releasing the rope 32, the mounting plate 221 and the device are moved downward to the ground, facilitating the maintenance and replacement of the device. The structure is simple, facilitating the installation of the device and reliable in hoisting.
