Description

Technical Field

[0001] The invention discloses a pile leg rotating gear ring locking mechanism and relates to the technical field of shore-connected trestle unloading channel equipment. Background Art

[0002] When constructing a trestle in the coastal waters, pile legs are used to raise the trestle platform above the water surface. At this time, the pile legs of the trestle need to be vertical or diagonally supported with the trestle platform. The pile legs are slender column structures, which means that during transportation, the pile legs need to be folded to be placed parallel to the trestle platform. Therefore, the previous integral elevated trestle pile leg solutions cannot meet the requirements. Most of the existing pile legs and platforms are directly fixed vertically, which cannot realize the rotation and folding of the pile legs, and cannot set diagonal piles at any angle. Summary of the invention

[0003] In view of the defects in the above-mentioned background technology, the present invention provides a pile leg rotating gear ring locking mechanism, which can realize the locking of inclined piles at any angle, provides a solution to the problem of elevated trestle bridges bearing horizontal forces, and solves the problem of folding, loading and transporting pile legs of elevated trestle bridge modules during transportation.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a pile leg rotating gear ring locking mechanism, comprising: a platform, a pile fixing frame, a rotating gear ring and a locking mechanism;

[0005] The rotating gear ring is fixedly connected to the platform, and the pile fixing frame is connected with a locking mechanism adapted to the rotating gear ring; the pile fixing frame is connected with a rotating bracket adapted to the rotating gear ring, and the rotating bracket is connected to the outer side of the rotating gear ring and is slidably connected to the rotating gear ring. The rotating bracket limits the rotation trajectory of the rotating gear ring and supports the rotating gear ring;

[0006] The locking mechanism comprises: a locking tooth block, a fixed slide plate, a guide mechanism and a driving mechanism, wherein the fixed slide plate is connected to a side of the guide mechanism away from the pile fixing frame;

[0007] The pile fixing frame rotates around the center of the rotating gear ring, and the platform is in rotational contact with one end of the central shaft. The central shaft is arranged at the center of the rotating gear ring, and the other end of the central shaft is fixed to the pile fixing frame. The locking tooth block reciprocates along the guide mechanism toward the inner side of the rotating gear ring under the cooperation of the driving mechanism and the fixed slide plate, driving the locking tooth block to engage or disengage with the rotating gear ring, so as to lock and unlock the rotating gear ring and control the rotation angle position of the pile fixing frame relative to the platform.

[0008] Furthermore, the locking tooth block is designed in a convex shape, and the large-size side of the locking tooth block is close to the rotating gear ring. The guide mechanism includes: a positioning plate, the positioning plate is connected to the pile fixing frame, and the positioning plates are symmetrically arranged along both sides of the locking tooth block. The guide mechanism is designed in a convex shape with openings at both ends.

[0009] Furthermore, the locking tooth block includes: a support body, a locking tooth and a tail handle; the support body and the tail handle are integrally connected, the front end of the support body is connected to the locking tooth adapted to the rotating gear ring, and the locking tooth block is used to connect with the driving mechanism through the slide groove, and under the action of the driving mechanism, the locking tooth block is driven to move toward the rotating gear ring side.

[0010] Furthermore, the driving mechanism includes: a driving connecting rod, a locking shaft, a pushing shaft and a driving cylinder. The two sides of each end of the pushing shaft are respectively connected to the locking shaft through a driving connecting rod. A sliding groove compatible with the driving mechanism is provided on the locking tooth block. Under the action of the driving cylinder, the locking shaft and the pushing shaft switch between a triangular distribution and a linear distribution, driving the locking tooth block to move toward or away from the rotating gear ring.

[0011] Furthermore, the fixed slide plate comprises: a convex plate body, on which are provided: a first push shaft slide groove and a first locking slide groove, the first push shaft slide groove is a strip-shaped groove, the first locking slide groove is an L-shaped groove, the first locking slide groove is symmetrically arranged at both ends of the first push shaft slide groove, the locking shaft is arranged in the first locking slide groove, and the push shaft is arranged in the first push shaft slide groove;

[0012] The locking tooth block is provided with: a second locking groove and a second pushing shaft groove, the second pushing shaft groove is arranged at the center of the locking tooth block, the second locking groove is symmetrically arranged at both ends of the second pushing shaft groove, and the second locking groove is designed to be perpendicular to the second pushing shaft groove, the locking shaft is arranged in the second locking groove, and the pushing shaft is arranged in the second pushing shaft groove.

[0013] Furthermore, both ends of the first push shaft slide groove and the first locking slide groove are semicircular in design;

[0017] The locking mechanism is provided with two at the center of the rotating gear ring, thereby improving the stability of the locking mechanism.

[0018] The locking mechanism has two working states: locked and unlocked. In the locked state, the pile frame is relatively fixed to the platform to ensure that the position of the pile legs is fixed. In the unlocked state, the pile frame can rotate relative to the platform to switch the pile legs between the folded state and the elevated state.

[0019] When locking is required, under the drive of the synchronously working driving cylinder, the locking shaft of the driving connecting rod of the driving mechanism moves along the longitudinal groove of the first locking slide groove, pushing the locking tooth block to engage with the rotating gear ring. When the locking tooth block begins to engage with the rotating gear ring, the pushing shaft continues to move forward along the first pushing shaft slide groove, and the driving connecting rod pushes the locking shaft to move along the transverse groove of the first locking slide groove until the pushing shaft and the locking shafts on both sides and the driving connecting rod therebetween are in a straight line, and the locking shaft simultaneously enters the locking position on the fixed slide groove plate. At this time, the locking tooth block is completely locked by the locking shaft, and the driving cylinder is in a stress-free state.

[0020] When unlocking is required, the driving cylinder pulls the locking gear block driving mechanism connecting rod through the central pushing shaft, and the locking shaft is pulled out from the locking position of the first locking slot on the fixed slot plate and the locking position of the end of the second locking slot on the locking gear block, and the locking gear block slides backward to unlock.
