Description
Technical Field
The utility model relates to a tensioning screw nut device, and belongs to the technical field of bridge tensioning auxiliary equipment.
Background
A cable-stayed bridge and a suspension bridge are used as main building modes of modern bridges, the cable-stayed bridge is also called an oblique-tension bridge, the main beam is directly pulled on a bridge tower by a plurality of pull cables, and the cable-stayed bridge is a structural system formed by combining a pressure-bearing tower, the pulled cables and a bending-bearing beam body. Suspension bridges, also known as Suspension bridges (Suspension bridges), refer to bridges having main cables suspended by pylons and anchored on both banks or at both ends of the bridge as the main load-bearing members of the superstructure, a number of Suspension rods hanging down from the main cables to suspend the bridge deck, stiffening girders are normally provided between the deck and the Suspension rods, and a combined system is formed with the cables to reduce deflection deformation caused by live load.
No matter the cable is a stay cable of a cable-stayed bridge or a suspender of a suspension bridge or each strand of a main cable, the end part of each strand of the stay cable, the suspender or the main cable is provided with an anchor cup, and the anchor cup is anchored by a tensioning nut after sequentially passing through a preset cable guide pipe, a pressure bearing plate and a self-adjusting base plate. In the construction process, the tensioning machine is connected with the inner ring threads of the anchor cup for tensioning, so that the cable force of the inhaul cable, the main cable or the suspender is adjusted, and the cable force is fastened by rotating the tensioning nut. However, the following technical defects exist: when the tensioning nut is screwed, a round steel of phi 6 or phi 8 is usually inserted into a counter bore of the outer ring of the tensioning nut, and the tensioning nut is stirred by the round steel to rotate, so that time and labor are wasted; when the tensioning nut is adjusted, a tensioning machine is required to operate in a load-holding mode, and the construction risk is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a tensioning nut screwing device aiming at the prior art, which automatically screws a tensioning nut, saves time and labor and ensures the construction safety.
The technical scheme adopted by the utility model for solving the problems is as follows: a tensioning nut screwing device comprises a driving gear and a driven gear, wherein the driven gear and a positioning sleeve are fixedly arranged and are provided with a through central hole, and a tensioning nut is fixedly arranged in the central hole;
the driving gear is meshed with the driven gear; the positioning sleeve is arranged in the rotary hole of the motor base and can relatively rotate in the rotary hole of the motor base; the motor base is provided with a motor, and when the motor drives the driving gear to rotate, the driven gear, the positioning sleeve and the tensioning nut are driven to synchronously rotate.
The positioning sleeve is connected with the motor base through a sliding sleeve.
An oil cup is arranged at the bottom of the motor base.
Compared with the prior art, the utility model has the advantages that: a tensioning nut is sleeved on a bolt of an anchor cup and is in threaded fit with the bolt. The motor is started to drive the driving gear to rotate, the driven gear, the positioning sleeve and the tensioning nut are driven to rotate, and the tensioning nut is automatically screwed into the bolt to fasten the cable force. This application simple structure, the simple operation can automatic screw nut moreover, and labour saving and time saving has guaranteed construction safety.

As shown in fig. 1, the tensioning nut screwing device in this embodiment includes a driving gear 2 and a driven gear 3, a tensioning nut 7 penetrates through a central hole of the driven gear 3, and the driven gear 3 and the tensioning nut 7 are fixedly connected through a bolt; and the tensioning nut 7 is sleeved in the central hole of the positioning sleeve 6, and the positioning sleeve 6 and the driven gear 3 are arranged in parallel and fixedly connected through a bolt. The driving gear 2 and the driven gear 3 are arranged up and down and are meshed with each other. The locating sleeve 6 is arranged in a rotary hole of the motor base 4, and the locating sleeve 6 is connected with the motor base 4 through the sliding sleeve 5, so that the locating sleeve 6 can rotate relatively in the motor base 4. Set up motor 1 on the motor base 4, fixed connection driving gear 2 on the 1 output shaft of motor, motor 1 drive driving gear 2 is rotatory, drives driven gear 3 rotatory for position sleeve 6 and tensioning nut 7 synchronous revolution.
An oil cup 8 is arranged at the bottom of the motor base 4.
And sleeving the tensioning nut 7 on the bolt of the anchor cup, wherein the tensioning nut 7 is in threaded fit with the bolt. The motor 1 is started to drive the driving gear to rotate, the driven gear, the positioning sleeve and the tensioning nut are driven to rotate, and the tensioning nut is automatically screwed into the bolt to fasten the cable force. This application simple structure, the simple operation can automatic screw nut moreover, and labour saving and time saving has guaranteed construction safety.
