Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not limit the present invention.

[0022] like figure 1 — Figure 4 As shown, the present invention includes a clamping device for clamping with the traction track 2. The clamping device includes a main shaft 1.1, two groups of intersecting rotating arms 1.2 whose center is hinged on the main shaft 1.1 and is connected to the end of the rotating arm 1.2. A clamping plate 1.3 for fixed clamping with the traction rail 2, a bolt 1.8 for fixing the rotating arm 1.2 is installed at the end of the main shaft 1.1, a reinforcing rib 1.9 is provided on the clamping plate 1.3, and the clamping plate The end of 1.3 is provided with a buffer block 1.5 that protrudes from the clamping plate 1.3, and the buffer block 1.5 includes a rectangular block 1.51 that collides head-on w...

Abstract

The invention relates to a track tackle stop device, and belongs to the technical field of vehicle collision test equipment. The track tackle stop device comprises holding devices used for holding traction tracks. Buffer blocks protruding out of the holding devices are arranged on the end portions of the holding devices; clamping structures are arranged on the holding devices; friction plates are arranged on the binding surfaces, used for holding the traction tracks, of the holding devices. The track tackle stop device is simple in structure, small and exquisite in size, flexible to install, capable of being installed in any position of automobile collision test traction tracks and adjustable in clamping force, will not damage the tracks, and can brake a track tackle effectively through the friction force generated between the friction plates and the tracks and achieve braking and traction releasing of the tackle in any position in automobile direct collision, side collision and frontal collision tests and bring great convenience to the collision tests.

Description

technical field [0001] The invention belongs to the technical field of vehicle collision test equipment, and in particular relates to a stop device for a rail trolley. Background technique [0002] In the vehicle crash test, traction track and traction block are important test equipment. During the frontal impact test, after the traction block drives the test vehicle to reach a predetermined speed, the traction block suddenly stops and disengages from the test vehicle, and the test vehicle hits the collision wall at free speed. In this scenario, both the stop position of the traction block and the position of the impact wall are fixed. However, in tests such as vehicle offset collision, side collision, and vehicle-to-vehicle collision, the requirements for the position of the traction release point are very flexible. However, due to the diversity and expansibility of the test forms, it is impossible to design a fixed traction release point and pulley traction device for ea...
