DETAILED DESCRIPTION

[0026] The present invention is further described in detail below through specific examples. The following examples are only illustrative and not restrictive, and the protection scope of the present invention cannot be limited thereto.

[0027] A lifting and releasing device for a drop test of a large package, the innovation of which lies in: comprising a guide rail body 3, a fixed-end clamping arm 2 being installed on the left side of the guide rail body 3, the lower end of the fixed-end clamping arm 2 being fixedly connected to a clamping panel 1, a lifting ear 5 being fixedly installed on the left end of the guide rail body 3, a connecting rod structure 9 being installed in the middle part of the guide rail body 3, the left end of the connecting rod structure 9 being hinged on the guide rail body 3, the right end of the connecting rod structure 9 being slidably installed in a slide groove 13 of the guide rail body 3, the right end of the connecting rod structure 9 being connected to a moving-end clamping arm 12, the lower end of the moving-end clamping arm 12 being fixedly connected to the clamping panel 1, an electromagnetic releaser 8 being installed on the top end of the connecting rod structure 9, a lifting ring 7 being installed on the top end of the electromagnetic releaser 8, a cable motor 11 being fixedly installed on the right end of the guide rail body 3, a steel cable 14 being rigidly connected to the lifting ear 5, the other end of the steel cable 14 passing through the electromagnetic releaser 8 and being connected to the cable motor 11.

[0028] A drum 10 is installed at the right end of the guide rail body 3, and the steel cable 14 is wound around the drum 10 to guide the noose and ensure the stability of the lifting.

[0029] A fixing plate 15 is installed in the guide rail body 3 on the right side of the fixed end clamping arm 2, a supporting spring 6 is connected between the fixing plate 15 and the fixed end clamping arm 2, a supporting screw 4 is connected to the left side of the fixed end clamping arm 2, a hand wheel is provided on the supporting screw 4, and the fixed end support arm completes the position adjustment and clamping limit function through the supporting screw and the supporting spring.

[0030] The right end of the connecting rod structure 9 is connected with an X-shaped connecting rod 16, and the X-shaped connecting rod 16 is clamped in a guide groove 17 arranged parallel to the guide rail body 3. The connection positions of the X-shaped connecting rod 16 and the connecting rod structure 9 are both provided with roller bearings to ensure that the connecting rod structure drives the horizontal and stable sliding of the clamping arm at the moving end to achieve stable clamping of the package.

[0031] A damping patch 18 is attached to the inner wall of the clamping panel 1 to increase the friction between the package and the clamping panel and ensure the clamping stability.

[0032] The working principle of the present invention is:

[0033] When in use, first adjust the fixed end clamping arm to a suitable position according to the size of the clamped object, connect the electromagnetic releaser, the lifting ring and the overhead crane hook, and after lifting the hook, the clamping arm will gradually tighten and clamp the package until it is lifted to the test height;

[0034] After turning on the noose motor and tightening the steel cable to an appropriate length, press the electromagnetic release switch and the hook door will open. The entire clamp will not fall due to the suspension of the steel cable, and the connecting rod will fall by its own weight after losing the lifting force. The clamping arm will lose its clamping ability and the package will fall at a predetermined height, thereby completing the large package drop test.

[0035] During the test, the gripping position and angle of the package can be adjusted to achieve a flat drop of large packages (such as Figure 3 As shown), edge drop test (as shown Figure 4 This ensures the repeatability of the test and the reliability of the test data.
