Description

Technical Field

[0001] The utility model belongs to the technical field of bridges, and in particular relates to a height-adjustable bridge swivel support leg. Background Art

[0002] A rotating bridge is a bridge constructed using the rotation method. Bridge rotation construction involves fabricating (casting or splicing) the bridge structure in a location other than the design axis and then rotating it into place.

[0003] When there is an error in the height of the swivel, it is necessary to fine-tune the height using multiple screws, which is troublesome to screw one by one, resulting in the problem that it is difficult to adjust the height of a conventional bridge swivel.

[0004] To this end, we proposed a height-adjustable bridge swivel support to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that it is difficult to adjust the height of a conventional bridge swivel, and to propose a height-adjustable bridge swivel support leg.

[0007] A height-adjustable bridge swivel support leg includes a pillar, wherein the upper portion of the pillar is movably embedded with a threaded seat, the threaded seats are evenly distributed in a ring, the internal threads of the threaded seat are installed with bolts, the upper ends of the bolts are fixedly connected to a support, the lower ends of the support are fixedly connected to a plug, the plug is slidably inserted into the pillar, the lower portion of the threaded seat is engaged with a gear ring, the outer periphery of the gear ring is fixedly connected to a pull rod, and the outer end of the pull rod is fixedly connected to a pull ring. After the device is installed, when there is a small error in the rotating bridge body, the pull ring is pulled by a crane, the pull ring acts on the pull rod, and the pull rod acts on the gear ring, and the gear ring drives the threaded seat to rotate, so that the threaded seat drives the bolt to rise or fall, which is convenient for fine-tuning the height error of the rotating bridge body.

[0008] Preferably, a reinforcement rod is fixedly connected between the support and the pull rod, so as to increase the force range between the pull rod and the gear ring.

[0009] Preferably, the support comprises an oil platform and a column, the upper end of the oil platform being evenly provided with oil grooves, the side of the oil platform being provided with oil filling holes communicating with the interior space of the oil grooves, and the upper end of the column being fixedly connected to the lower end of the oil platform. Lubricating oil is injected into the oil grooves through the oil filling holes to facilitate reducing the rotational resistance of the threaded seat.

[0010] Preferably, the oil filling hole is plugged with a leather plug to prevent dust from entering the oil filling hole.

[0011] Preferably, the threaded seat includes a threaded sleeve, a retaining ring, a ring gear, and a washer. The retaining ring and the ring gear are fixedly connected to the lower portion of the threaded sleeve, and the lower end of the ring gear is fixedly connected to the upper end of the washer. When the gear ring rotates, the gear ring drives the ring gear to rotate, and the ring gear acts on the retaining ring, the threaded sleeve, and the washer, causing the washer to rotate along the oil groove, facilitating the gear ring to drive the threaded seat to rotate.

[0012] Preferably, the plug includes a plug body and a guide head, wherein the guide head is fixedly connected to the lower end of the plug body. The plug body is inserted into the middle of the oil platform to increase the stability of the center position of the support.

[0013] Preferably, the leather plug comprises an operating button and a plug body, wherein the plug body is fixedly connected to the operating button as a whole. The plug body is plugged into the oil filling hole to prevent dust from entering.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. After the device is installed, when there is a small error in the rotating bridge body, the pull ring is pulled by a crane, and the pull ring acts on the pull rod, and the pull rod acts on the gear ring, and the gear ring drives the threaded seat to rotate, so that the threaded seat drives the bolt to rise or fall, which is convenient for fine-tuning the height error of the rotating bridge body.

[0016] 2. Inject lubricating oil into the oil tank through the oil filling hole to reduce the rotation resistance of the threaded seat.

[0017] 3. When the gear ring rotates, the ring gear is driven to rotate through the gear ring, and the ring gear acts on the retaining ring, threaded sleeve and washer, causing the washer to rotate along the oil groove, making it easier for the gear ring to drive the threaded seat to rotate.
