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
[0032] 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 structure. 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 compo...

The invention provides a quick-switching bidirectional self-locking rail clamping crawler. The quick-switching bidirectional self-locking rail clamping crawler comprises a body, two wedge block groups, four pre-tightening mechanisms and two quick-switching mechanism, wherein a groove hole matched with a rail is formed in the bottom of the body; each wedge block group comprises two clamping wedge blocks; each pre-tightening mechanism comprises an opening and closing screw rod, a pre-tightening spring, a pre-tightening seat and an opening and closing screw rod end hinge, each opening and closing screw rod is sequentially sleeved with the corresponding pre-tightening spring, the corresponding pre-tightening seat and the corresponding opening and closing screw rod end hinge, one end of each pre-tightening spring abuts against the corresponding clamping wedge block, and the other end of each pre-tightening spring abuts against the corresponding pre-tightening seat; each quick-switching mechanism comprises a linkage screw, two double-arm rockers and two sliding swing hinges, every two sliding swing hinges are loosely arranged at the two ends of each linkage screw in a sleeving manner correspondingly, each linkage screw is rotationally connected with the double-arm rockers, the sliding swing hinges are slidably connected with the double-arm rockers, one ends of the double-arm rockers are rotationally connected with the body, the other ends of the double-arm rockers are rotationally connected with the opening and closing screw s, and each opening and closing screw end hinge is connected with the corresponding double-arm rocker in a sliding manner. The double-arm rockers and the pre-tightening mechanisms are driven to act by rotating the linkage screws, and opening and closing switching of the two wedge block sets is achieved.
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. ...
