Description

Technical Field

[0001] The utility model relates to the technical field of stability detection, in particular to a crane stability detection device. Background Art

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. It is also called an overhead crane, overhead crane, or crane. The stability of the crane is one of the essential safety monitoring measures during the operation of the crane.

[0003] When a crane is lifting, it is in a dynamic balance process. When one or both legs of the crane are lifted off the ground, making it impossible for the crane to lift normally, it is called instability. The relevant standards stipulate that the standard for the critical state of stability is "the height increment of the calibration point on the outer edge of a fixed leg on the opposite side of the boom from the ground reaches 50 mm, or the height increment of the calibration points of two legs from the ground reaches 5 mm at the same time." In the unstable state, the crane is very likely to overturn. In the existing technology, there is a lack of detection equipment for the stability of the crane legs, making it difficult to judge the occurrence of instability, which is not conducive to the operator to adjust the crane according to the situation.

A crane stabilizer 3 is rotatably installed on the inner surface of the placement groove 2. The crane stabilizer 3 includes an extension rod 31, a support column 32, a hydraulic cylinder 33, a hydraulic rod 34 and a support plate 35. A stability detection mechanism 4 is fixedly installed on the outer surface of the support column 32. The stability detection mechanism 4 includes a clamping column 401, a fixing frame 402, a spring 403, a clamping tooth block 404, a ratchet 405, a connecting frame 406, a detection rod 407, a positive contact plate 408, a negative contact plate 409, a metal ball 410, an electric wire 411, a signal light 412 and a horn 413.

[0029] like Figure 1and 2 As shown, stability detection mechanisms 4 are respectively installed on both sides of the support column 32, so that the support column 32 can detect whether there is any tilt in real time.

[0030] like Figure 1 and 2 As shown, the bottom of the extension rod 31 is fixedly connected to the top of the support column 32 , and the inner cavity of the support column 32 is fixedly connected to the outer surface of the hydraulic cylinder 33 .

[0031] like Figure 1 and 2 As shown, the inner surface of the hydraulic cylinder 33 is fixedly connected to the outer surface of the hydraulic rod 34 through a piston, and the bottom end of the hydraulic rod 34 is fixedly connected to the top of the support plate 35.

[0032] like Figure 2-4 As shown, the inner surface of the clamping column 401 is fixedly connected to the outer surface of the fixing frame 402 , one end of the spring 403 is fixedly connected to the inner wall of the fixing frame 402 , and the other end of the spring 403 is fixedly connected to the outer surface of the locking tooth block 404 .

[0033] like Figure 2-4 As shown, the outer surface of the latch block 404 is slidably connected to the inner surface of the fixing frame 402 , the outer surface of the latch block 404 is slidably connected to the outer surface of the ratchet 405 , and the outer surface of the ratchet 405 is fixedly connected to the inner surface of the connecting frame 406 .

[0034] like Figure 2-4 As shown, the inner surface of the connecting frame 406 is fixedly connected to the outer surface of the detection rod 407, the inner surface of the detection rod 407 is fixedly connected to the outer surface of the positive contact plate 408, the outer surface of the support column 32 is fixedly connected to one end of the wire 411, and the other end of the wire 411 is fixedly connected to the top of the connecting frame 406.

[0035] like Figure 2-4 As shown, the inner cavity of the detection rod 407 is fixedly connected to the outer surface of the negative contact plate 409, the inner surface of the detection rod 407 is slidingly connected to the outer surface of the metal ball 410, the front of the support column 32 is fixedly connected to the back of the signal light 412, and the right side of the support column 32 is fixedly connected to the left side of the speaker 413.

[0036] like Figure 2 and 4 As shown, there is a transparent portion on the detection rod 407, which allows the position of the internal metal ball 410 to be checked, so as to adjust the horizontal position of the detection rod 407.

[0037] like Figure 2 As shown, the signal light 412 can emit red, yellow and green lights. After tilting occurs, the signal light 412 emits red and yellow lights, and the speaker 413 emits a warning sound to warn the construction workers that the crane 1 has tilted.

[0038] In summary, the user first stops the crane 1, then takes out the extension rods 31 on both sides from the placement slot 2, and places them at a 90-degree angle with the crane 1, then the hydraulic cylinder 33 drives the hydraulic rod 34 to move, and the hydraulic rod 34 drives the support plate 35 to move downward to support the crane 1, and then installs the connecting frame 406 equipped with the detection rod 407 into the card column 401, inserts the ratchet 405 of the connecting frame 406 into the card column 401, so that the tooth block 404 is engaged with the ratchet 405, and by rotating the connecting frame 406, the detection rod 407 is placed horizontally, and then the wire is used to connect the connecting frame 406 to the detection rod 407. The two ends of 411 are respectively inserted into the connecting frame 406 and the support column 32. When the crane 1 tilts, the metal ball 410 in the detection rod 407 rolls in the detection rod 407, causing the metal ball 410 to touch the positive contact plate 408 and the negative contact plate 409, so that the positive contact plate 408 and the negative contact plate 409 are connected. The signal is connected to the signal light 412 and the speaker 413 through the wire 411. The signal light 412 emits a red warning light and the speaker 413 emits a warning sound, so that the construction workers can immediately notice the problem of the crane 1 tilting and stop construction immediately.
