Problems solved by technology
Although the current two-way clamp rail crawler does not need to be hoisted out and the crawler is rotated in reverse, it still needs to manually adjust the front and rear direction pre-tightening seats and the nuts on the opening and closing screw. , especially for the adjustment of the bolts and nuts at the lower part of the ear plate, the working space is limited and the adjustment is difficult

Embodiment Construction
[0033] In order to make the purpose, advantages and features of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are all in very simplified form and not drawn to scale, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, the structures shown in the drawings are often a part of the actual structures. In particular, each drawing needs to display different emphases, and sometimes uses different scales. It should also be understood that, unless otherwise specified or pointed out, the terms “first”, “second”, “third” and other descriptions in the specification are only used to distinguish each component, element, step, etc. in the specification, rather than It is used to express the logical relationship or sequence relationship between various comp...

The invention provides a fast-switching two-way self-locking rail crawler, which includes: a body, the bottom of which is provided with a slot for matching with the rail; two wedge groups, and each wedge group includes two clamping wedges; four Each preloading mechanism includes a split screw rod and a preload spring, a preload seat and an end hinge of the split screw rod that are sequentially sleeved on the split screw rod. One end of the preload spring abuts against the clamping wedge, The other end touches the pre-tension seat; two quick switching mechanisms, the quick switching mechanism includes a linkage screw, two double-arm rockers and two sliding swing hinges, and the two sliding swing hinges are respectively loosely sleeved on both ends of the linkage screw, and the linkage The screw rod is rotatably connected to the double-arm rocker, and the sliding swing hinge is slidably connected to the double-arm rocker. One end of the double-arm rocker is rotatably connected to the body, and the other end is rotatably connected to the opening and closing screw, and the end of the opening and closing screw is hinged to the double arm The rocker slides to connect. By rotating the linkage screw to drive the action of the double-arm rocker and the pre-tightening mechanism, the opening and closing switching of the two wedge groups is realized.
Description
technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a fast-switching two-way self-locking rail crawler. Background technique [0002] When large structures or equipment slip in the installation field, a large number of rail crawler jacking techniques are used. Currently commonly used hydraulic crawlers include one-way clamp rail crawler and two-way clamp rail crawler. Since the one-way clip rail crawler has one-way self-locking property, if it needs to be displaced in the opposite direction during the pushing process, it is necessary to install the crawler on the other side of the heavy object or hang the crawler out, rotate it 180 degrees and then Install and use. Although the current two-way clamp rail crawler does not need to be hoisted out and the crawler is rotated in reverse, it still needs to manually adjust the front and rear direction pre-tightening seats and the nuts on the opening and closing screw. ...
