Description

Technical Field

[0001] The utility model relates to the technical field of mine derrick level detection, in particular to a portable mine derrick level detector. Background Art

[0002] In mining development, it is necessary to erect a metal derrick or tower crane. During construction, the horizontality of the frame must be checked from time to time to prevent tilting, which can cause serious consequences.

[0003] In the prior art, a level ruler is mostly used for measurement, but the level ruler is often placed on a beam for measurement, and there are four beams on the same layer of the frame structure. Even if the level of each beam is qualified, it is impossible to confirm whether the two adjacent beams are at the same height, which makes the detection incomplete. Therefore, for the sake of industry technological progress, the level detection function can be better realized and the competitiveness of core technology can be improved. This application proposes a level detector that is different from the prior art. Utility Model Content

[0004] The utility model aims to solve the problem that the existing level ruler cannot confirm whether two adjacent beam frames are at the same height during use, and proposes a portable mine derrick level detector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A portable mine derrick level detector comprises two level detector bodies and support plates. The two level detector bodies are respectively fixed on the two support plates. A magnetic block 1 and a magnetic block 2 with opposite magnetic properties are respectively fixed on the ends of the two support plates that are close to each other. When the magnetic block 1 and the magnetic block 2 are adsorbed, the two support plates are perpendicular to each other, and a magnetic plate is embedded on one side of the two support plates that are in contact with each other.

[0007] Furthermore, the two support plates are rotatably connected via a limit hinge.

[0008] Furthermore, the top of one of the support plates is fixedly connected to the first top plate, and the top of the other support plate is fixedly connected to the second top plate.

[0009] Furthermore, handles are fixedly connected to the tops of the first top plate and the second top plate.

[0010] Furthermore, the support plate and the bottom of the level detector body are bonded with a same anti-slip magnetic pad.

[0011] Furthermore, the two magnetic plates have opposite magnetic properties.

[0012] Furthermore, the maximum rotation angle between the two support plates is 90 degrees.

[0013] The beneficial effects of the utility model are:

[0014] 1. By rotating the two support plates outward, the two level detector bodies are rotated to a vertical state. The limit hinges, magnetic blocks 1 and 2 can stabilize the vertical state, making it easier to detect two beams at the same time, ensuring that the two adjacent beams are at the same height, and improving the detection capability of the derrick.

[0015] 2. Through the setting of anti-slip magnetic pads, the device can be adsorbed according to the characteristics of the derrick being metal. Anti-slip textures are also set under the anti-slip magnetic pads. In addition to the adsorption ability, the stability of the level detector is improved by increasing the friction.

[0016] 3. The two level detector bodies are fixed by the attraction of two magnetic plates, so that the level detection device is easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5A portable mine derrick level detector comprises two level detector bodies 2 and two support plates 1. The two level detector bodies 2 are respectively fixed to the two support plates 1 by bolts. The two support plates 1 are rotatably connected by a limit hinge 8. The maximum rotation angle of the limit hinge 8 is 90 degrees. Therefore, the two support plates 1 are rotated outward to rotate the two level detector bodies 2 to a vertical state.

[0025] The two support plates 1 are respectively fixed with a magnetic block 1 5 and a magnetic block 2 6 with opposite magnetic properties at one end thereof that is close to each other. When the two support plates 1 are rotated to a maximum angle of 90 degrees, the two support plates 1 are perpendicular to each other. At this time, the magnetic block 1 5 and the magnetic block 2 6 are mutually attracted and can stabilize the vertical state. At this time, the user can place them on two adjacent beams, thereby facilitating the simultaneous detection of the two beams and ensuring that the two adjacent beams are at the same height.

[0026] The top of one of the support plates 1 is fixedly connected to the first top plate 3, the top of the other support plate 1 is fixedly connected to the second top plate 4, the tops of the first top plate 3 and the second top plate 4 are both fixedly connected to handles 7, and a magnetic plate 10 is embedded in one side of the two support plates 1 that are in contact with each other. The two magnetic plates 10 have opposite magnetic properties. When closed, the two support plates 1 fit tightly together and will not shake, making them easy to carry.

[0027] The support plate 1 and the bottom of the level detector body 2 are bonded with the same anti-slip magnetic pad 9, so that the device can be adsorbed according to the characteristics of the derrick being metal. Anti-slip textures are also provided under the anti-slip magnetic pad 9. In addition to the adsorption ability, the stability of the placement of the level detector is improved by increasing the friction.

[0028] The working principle of this embodiment: when in use, first, rotate the two support plates 1 outward, so as to rotate the two level detector bodies 2 to a vertical state, and then the user can place it on two adjacent beams, so as to facilitate the simultaneous detection of the two beams and ensure that the two adjacent beams are at the same height; if necessary, the two level detector bodies 2 can be placed close to the connecting column between the two beams, and the two surfaces of the connecting column can be judged by the fit whether they are vertical surfaces.

[0029] After the detection is completed, the two level detector bodies 2 are combined together, and then the two level detector bodies 2 are fixed by the attraction of the two magnetic plates 10, and then the handle 7 is held, so that it is convenient to carry the level detection device.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
