Description

Technical Field

[0001] The utility model relates to the technical field of bridge erection machine construction, and more specifically, to a foldable track connecting clamp. Background Art

[0002] When using a bridge erection machine to erect the beams of a bridge, the front legs of the bridge erection machine need to move horizontally through the underlying rails, and the length of the rails is generally more than 20 meters; and after the bridge erection machine completes the erection of one hole of the beam, the front legs of the bridge erection machine need to hang the rails and move forward one hole. At this time, the overhang of the two ends of the rails is too long, which will cause construction inconvenience. In actual construction, the method of dividing the rails into two track segments along the length direction is usually adopted. Each track segment is about 10 meters long. Each time the rails are moved forward, they need to be disassembled into two track segments for synchronous movement. After the forward movement is completed, the two track segments are connected into a whole. Although this method solves the problem of the overhang of the deformed rails when the bridge erection machine moves forward, each time the rails are disassembled and assembled, it is time-consuming and labor-intensive, and the operation is inconvenient, which seriously affects the efficiency of bridge construction.

[0003] In order to solve the above problems, it is necessary to design a foldable track connecting splint to improve the convenience and construction efficiency when the track moves forward with the bridge-building machine legs. Utility Model Content

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0027] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] like Figure 1-6 As shown, the utility model provides a foldable track connecting splint, comprising:

[0029] Two groups of connecting splints, which are respectively arranged on both sides of the track, each group of connecting splints includes two connecting splints, which are respectively arranged at the adjacent ends of two track segments 5, and the two connecting splints located on the same track segment are arranged opposite to each other, and each connecting splint is arranged along the length direction of the track and fixedly connected to the side wall of the corresponding track segment;

[0030] A rotating shaft 6, which is arranged on one side of the track along the height direction thereof and is rotatably connected to two connecting clamping plates on the same side respectively;

[0031] A locking device, which is arranged on the other side of the track and is used to limit the relative rotation of the two connecting clamping plates on the same side;

[0032] Among them, in the initial state, the locking device is in a limited state, and the two connecting splints in the same group are set at 180°; in the fully folded state, the locking device is in a non-limited state, and the two connecting splints in the same group are set at 0°.

[0033] In the above technical solution, it is assumed that: a group of connecting splints arranged on one side of the rotating shaft (i.e. the rotating side) are respectively the first connecting splint 1 and the second connecting splint 2, and a group of connecting splints arranged on one side of the locking device (i.e. the locking side) are respectively the third connecting splint 3 and the fourth connecting splint 4. Among them, the first connecting splint 1 and the fourth connecting splint 4 are relatively fixed on both sides of the same track segment 5, and the second connecting splint 2 and the third connecting splint 3 are relatively fixed on both sides of another track segment 5, and each connecting splint is fitted and connected with the corresponding track segment side wall. A rotating shaft 6 is provided between the first connecting splint 1 and the second connecting splint 2, and the rotating shaft can adopt a hinge structure, which is respectively hinged with the above two connecting splints and connects the two connecting splints into a whole, and the two track segments can rotate relative to each other around the rotating shaft in the horizontal plane to achieve extension and folding. Specifically, when the front leg of the bridge-building machine needs to move laterally along the track, the two track segments are adjusted to the initial state, that is, the two connecting splints are set at 180°, and the two track segments are continuously set along the same straight line, and their connecting end faces abut each other. At this time, the two corresponding (locking side) connecting splints are relatively fixed by the locking device, so that the two track segments can be stably maintained in a straight state (initial state), providing a stable running track for the front leg of the bridge-building machine; when the bridge-building machine needs to drive the track to move forward synchronously, it is necessary to first release the limit of the locking device, and then fold one of the track segments to the rotating side, so that the two connecting splints on the rotating side are close to each other to a relatively parallel state, that is, the two connecting splints are set at 0°, and the two track segments are completely folded to a parallel state. At this time, the folded track and the front leg of the bridge-building machine can be smoothly moved forward synchronously.

[0034] The utility model realizes the rapid switching of two adjacent track segments between the straight state and the folded state by cooperating with two groups of connecting splints and the rotating shaft. The locking device is used to limit the track segments and the connecting splints in the straight state. While ensuring the running stability of the front legs of the bridge-building machine, it solves the problems of excessive cantilever of the running rails and long time-consuming disassembly, installation and restoration when the bridge-building machine moves forward, thereby improving the efficiency of bridge construction.

[0035] In another technical solution, the foldable track connecting splints are clamped in the grooves on both sides of the I-shaped track. In the initial state, the two connecting splints in the same group are continuously arranged along the same straight line and the connecting end faces abut against each other. Specifically, in this embodiment, the track is made of I-beams, which, on the one hand, facilitates the stable (no-fall-off) sliding connection between the front legs of the bridge erecting machine and the track, and on the other hand, grooves can be naturally formed on both sides of the track, which facilitates the installation of each connecting splint and its supporting components. The connecting splint is fitted and clamped on the inner wall of the track, and the outer edge of the connecting splint will not exceed the outer edge of the track (that is, the thickness of the connecting splint will not exceed the length of the bottom plate of the I-shaped track extending out of the side plate). Therefore, when the two track segments are relatively rotated and folded, the two connecting splints (the first connecting splint 1 and the second connecting splint 2) located on the inner side of the folding direction will not interfere with each other and hinder the track segments from folding to a parallel state, so that the two track segments 5 can be rotated to a fully folded state. At this time, the sides of the bottom plates located on the inner side of the two track segments are fitted and abutted against each other, and the first connecting splint 1 and the second connecting splint 2 are located above the above-mentioned bottom plates and are parallel to each other. In addition, in the initial state, the two connecting splints of the same group are continuously arranged along the same straight line, and their two adjacent end faces are fitted and abutted, so that each group of connecting splints forms a continuously arranged integral structure on the track, which is conducive to making the two track segments stably and accurately maintain a straight line state, and further strengthen the connection stability of the two track segments in the initial state, thereby ensuring the smooth travel of the front legs of the bridge erection machine.

[0036] In another technical solution, the two connecting clamps of the foldable track on the same track segment 5 are connected and fixed by bolts 7. Thus, the two connecting clamps can clamp the ends of the track segment and connect with them to form an integral structure. When the connecting clamps rotate relative to each other, the track segments can be stably driven to rotate relative to each other, so as to smoothly realize the switching of the track between the folded and extended states.

[0037] In another technical solution, the foldable track connecting clamp, the bolt includes a plurality of bolts, which are arranged on the side wall of the connecting clamp at intervals along the length direction of the connecting clamp, one end of any bolt 7 is fixed on the connecting clamp on the same side as the locking device and flush with its outer side wall, and the other end vertically passes through the corresponding two connecting clamps and is locked on the outer side wall of the connecting clamp on the same side as the rotating shaft 6 by a nut 8. In the above technical solution, the plurality of bolts can ensure the connection stability of the two connecting clamps on the same track segment, the head of the bolt 7 is flush with the outer side wall of the connecting clamp on the locking side and is fixedly connected, and the tail is locked by the nut 8 on the rotating side, which not only ensures the stability of the bolt tension connection, but also avoids the problem that the bolt as a connecting structure protrudes on the connecting clamp on the locking side and interferes with the locking device and its limit switching operation on this side. For the rotating side, only a rotating shaft is provided between the two connecting clamps, and the protrusion of the bolt or nut on the connecting clamp on this side will not affect its normal rotation operation. In this embodiment, the two connecting clamps on the same track segment are connected and clamped by three pairs of bolts.

[0038] In another technical solution, the foldable track connecting splint is set to have two connecting splints corresponding to the locking device, namely a left splint and a right splint; the locking device includes a limit plate 9, which is arranged on the left splint and extends to the right splint along its length direction; a limit groove 10, which is arranged on the outer side wall of the right splint corresponding to the limit plate 9, and the position and shape of the limit groove 10 match the limit plate, and in the initial state, the limit plate 9 and the limit groove 10 are engaged with each other. Among them, the left splint is the third connecting splint 3, and the right splint is the fourth connecting splint 4. In the initial state, the limit plate 9 located at the inner end of the left splint (close to the end of the right splint) is correspondingly embedded in the limit groove 10 on the right splint, which further improves the connection stability of the two track segments in the initial state, and ensures that the track will not rotate excessively during the process of switching from folding rotation to the initial state (that is, the two track segments fold in the opposite direction after rotating into a straight line).

[0039] In another technical solution, the foldable track connecting splint, the locking device also includes a plurality of locking members, which are arranged at intervals along the length direction of the limiting plate, any locking member includes two locking pin sleeves 11, which are relatively arranged on the upper and lower sides of the limiting groove 10, and any locking pin sleeve 11 is fixed to the right splint; a locking pin shaft 12, which includes a head and a rod, the diameter of the head is larger than the diameter of the rod, the rod fits into the two locking pin sleeves 11 along the height direction of the limiting groove 10, and the head is supported on the top of the locking pin sleeve 11 located above. In the above technical solution, the cooperation between the limiting plate 9 and the limiting groove 10 can limit the relative rotation of the corresponding two connecting splints in the same direction (clockwise / counterclockwise), and the locking member can further limit the relative rotation of the above two connecting splints in another direction. Specifically, the locking pin sleeve 11 is a horizontally arranged annular structure, and its inner diameter matches the outer diameter of the rod of the locking pin shaft 12. The rod of the locking pin shaft 12 is located on the opening plane of the limiting groove 10. When the two track segments 5 rotate to the initial state, the locking pin shaft 12 in each locking member is inserted into the corresponding two locking pin sleeves 11, and the limiting plate 9 can be locked in the limiting groove 10, so that the limiting plate 9 cannot rotate outward, thereby further locking the relative rotation displacement of the two connecting splints on this side; when the track needs to be switched to the folding state, each locking pin shaft 12 is pulled out, and the outward rotation of the limiting plate 9 is released, so that the rotation between the connecting splints and the folding of the track segments can be realized. The above-mentioned locking member has a simple structure and is easy to operate, which is conducive to the rapid and efficient state switching of the locking device, and strengthens the locking of the relative position of the connecting splints in the initial state, ensuring the walking stability of the front legs of the bridge erecting machine.

[0040] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
