Referring to fig. 1-5, the present embodiment provides a hanging weight sensor mounting device, which includes a left housing 1 and a right housing 2, wherein the left housing 1 and the right housing 2 are detachably connected. And the left shell 1 is provided with a connecting component for connecting the suspension arm of the tower crane. The left shell 1 is provided with a cavity with an opening on one side, and the cavity is internally provided with a connecting frame 3, a weight measuring sensor 4 and a clamping assembly. The head end of the connecting frame 3 penetrates through the shell wall on one side of the left shell 1 and can be connected with a lifting rope of a tower crane, the connecting frame is fixedly connected with the left shell, and the tail end of the connecting frame 3 is connected with the weight measuring sensor 4. While the clamping assembly is clamped or loosened relative to the load cell 4.

In the traditional scheme, the sensor is arranged on a steel wire rope wound by a balance pulley, and the steel wire rope and the sensor are firmly connected by a chuck, but the connection mode does not allow sliding, and the sensor and the tower body are often fixed by a fixing component to avoid relative sliding between the sensor and the tower body. Because the weight sensor 4 has a limited service life, the sensor needs to be periodically detected, debugged and replaced. However, the existing positioning assembly locks the sensor while keeping the sensor and the tower body fixedly connected, and the weight measuring sensor 4 is difficult to detect, debug and replace. In this scheme, the sensor is placed in the cavity formed by the left shell 1 and the right shell 2, and the left shell 1 and the right shell 2 can be detachably connected to separate at any time, so that the sensor can be detected and debugged. And through the tight weighing sensor 4 of centre gripping clamping assembly centre gripping, when needing to be changed weighing sensor 4, the clamping assembly loosens weighing sensor 4, conveniently changes weighing sensor 4.

As a specific embodiment, the connection assembly includes a connection plate 5, and the connection plate 5 is disposed on the outer wall of the left housing 1. The connecting plate 5 is provided with a threaded hole, and a bolt for connecting the connecting plate 5 and the tower crane boom is arranged in the threaded hole. When the left shell 1 is arranged on the tower crane boom, the left shell 1 is fixedly connected with the tower crane boom through the knob threaded hole. Of course, under the condition that the shell and the tower crane boom are fixed, other connecting modes in the prior art, such as welding, can also be adopted.

The centre gripping subassembly in this embodiment includes two grip blocks 6, left side casing 1's lateral wall is provided with the spout 8 that runs through left side casing 1's lateral wall, spout 8 sets up along left casing 1's direction of height, spout 8's head and the tail both ends head all communicates there is spacing groove 9, spacing groove 9's extending direction is perpendicular with spout 8's extending direction, and every grip block 6's lateral wall all is provided with slider 7, slider 7 slides in spout 8 and sets up, it is provided with the limiting plate to slide in spout 8, the width of limiting plate is greater than spout 8's width, the face of two grip blocks 6 is connected with left casing 1's roof or bottom plate through the spring respectively. After the weight measuring sensor 4 is arranged in the second cavity, the spring pushes the clamping plate 6 to clamp and fix the weight measuring sensor 4, so that the position of the weight measuring sensor 4 in the cavity is kept relatively fixed. When the weight sensor 4 needs to be replaced, the positioning of the weight sensor 4 can be released only by sliding the sliding block 7, so that the replacement is convenient. Meanwhile, the mode that the clamping plate 6 is pushed by the spring to clamp and fix the weight measuring sensor 4 also enables the mechanism to be applicable to weight measuring sensors 4 of any models.

In addition, a buffer mechanism 11 is also arranged in the cavity. The buffer mechanism 11 includes an upper substrate 12, a disc-type spring set, and a lower substrate 13. The disc-type reed set is positioned between the upper substrate 12 and the lower substrate 13, the surface of the upper substrate 12 is attached to the outer wall of the connecting frame 3, and the lower substrate 13 is attached to the inner wall of the cavity. The disc spring set is formed by longitudinally overlapping at least two pairs of disc springs 14, and the directions of the concave surfaces of the two adjacent disc springs 14 are opposite or the same. When the pulling force of lifting rope was used in the link 3, the load conducts for the dish formula spring group, the dish formula spring group has stable and fixed elastic coefficient, can correspond a certain amount of compression when the loading effect, can resume original shape again when the load was got rid of, utilize this characteristic just can have the process of a transition buffering to the load of loading on link 3, the direct atress of link 3 just can significantly reduce in the introduction of this process, after the buffering of load through the buffer, the load can become gentle, thereby just can not produce and lead to link 3 to damage because of the impact in the twinkling of an eye, improve the whole life-span of link 3 and casing. And the direct stress of the connecting frame 3 is reduced, the direct stress of the weight measuring sensor 4 is also reduced, and the service life of the weight measuring sensor 4 is indirectly prolonged. In addition, when the weight sensor 4 monitors the hoisting weight, the measured value is further converted according to the self-restoring force of the disc spring 14, so that an accurate hoisting weight value can be obtained.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
