Description

Technical Field

[0001] The invention belongs to the technical field of rapid construction of viaducts, and in particular relates to a device for rapid construction of urban viaducts and a use method thereof. Background Art

[0002] Urban viaduct refers to a bridge that crosses the road in the city and is supported by high-supported towers or pillars. In order to ensure the normal operation of traffic in the city, special rapid construction equipment is generally used to shorten the construction period. Depending on the type of processing, the devices used also have corresponding differences, including a stranded wire threading machine for transmitting steel strands.

[0003] During the wire insertion process of the existing rapid construction device, the opening diameter of the end tube is small, which leads to the problem of difficulty in alignment during the insertion process, thus seriously affecting the processing efficiency. The common existing processing method is manual alignment. Once the operation is not careful, the end of the steel strand will cause damage to the human hand. In the early debugging of the motor, the motor needs to be fixed, and then the device is started to check whether there is a fault or transmission deviation. Once there is a problem, the connecting bolts need to be removed, so there are relatively cumbersome problems. Summary of the invention

[0004] The object of the present invention is to provide a device for rapid construction of urban viaducts and a method for using the device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for rapid construction of urban viaducts, comprising a base frame, an operation box is installed on one side of the top surface of the base frame, end pipes are arranged at both ends of the operation box, and the two end pipes are respectively an outlet pipe and an inlet pipe, a guide sleeve is screwed into the end of the end pipe at the inlet pipe through a thread, a limiting ring is fixed to the surface of the end pipe at this place, one end of the guide sleeve is abutted against the limiting ring, an inner guide tube is also fixed inside the guide sleeve, the inner guide tube is bent and extended toward one end of the guide sleeve, and is clamped into the inner wall of the opening of the end tube, the inner wall of the guide sleeve is also provided with a plurality of ball grooves, and a ball is also clamped on the inner side of each ball groove.

[0006] Preferably, a support rod is symmetrically fixed to the outside of one end of the guide sleeve, the support rod abuts against the end surface of the operation box, and the support rod is fixed to the guide sleeve by welding.

[0007] Preferably, the other end of the guide sleeve expands and extends outward, and the longitudinal section of the guide sleeve is in an "eight"-shaped structure.

[0008] Preferably, a motor is arranged on the other side of the top surface of the bottom frame, the output end of the motor is transmission-connected to the operation box, and a mounting plate is also fixed to the bottom end of the motor.

[0009] Preferably, screw holes are provided on the surfaces of the mounting plate and the bottom frame, and a limiting bolt is passed through the inside of the screw hole. An insertion hole is provided at the bottom of the limiting bolt, and a bayonet is passed through the inner side surface of the bottom frame, and one end of the bayonet is connected to the insertion hole. A telescopic spring is also sleeved on the surface of the limiting bolt, and the telescopic spring is located between the limiting bolt and the mounting plate.

[0010] Preferably, the top of one end of the bayonet toward the limiting bolt is inclined, and the outer surface of the limiting bolt is a smooth curved structure.

[0011] A method for using a device for rapid construction of an urban viaduct, specifically comprising the following steps:

[0012] Step 1: First, screw one end of the guide sleeve onto the open end of the end pipe through a thread until the support rod abuts against the operation box, and one end of the guide sleeve abuts against the limit ring. At the same time, the opening of the inner guide tube also extends to the inner wall of the end pipe. During operation, insert the steel strand into the guide sleeve, and increase the insertion area through the opening at the other end of the guide sleeve. At the same time, guide it through the inner guide tube to avoid the steel strand from being stuck against the end face of the end pipe.

[0013] Step 2: When the steel strand hits the ball on the guide sleeve during insertion, the guide transmission can be completed by the rotation of the ball to avoid long-term jamming. When the steel strand hits the inner wall of the guide sleeve, the guide sleeve can be supported by the support rod to prevent the guide sleeve from tilting to one side.

[0014] Step 3: When debugging the device after the early production, first place the motor on the bottom frame, set the telescopic spring on the limit bolt, and then pass the limit bolt through the mounting plate and the bottom frame. At this time, press the limit bolt downward to deform the telescopic spring;

[0015] Step 4: Insert the bayonet from the inside of the bottom frame until it penetrates into the inside of the socket, then release the limit bolt. Under the rebound of the telescopic spring, the bottom inner wall of the socket fits with the bottom end surface of the bayonet, thereby completing the installation limit of the limit bolt. After debugging is completed, separate the limit bolt from the bayonet, and then install the bolt normally.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The designed guide sleeve can increase the diameter of the end tube, thus facilitating the insertion of the steel strand. The designed inner guide tube can also ensure that the steel strand is smoothly inserted into the end tube. The designed ball can provide auxiliary guidance for the steel strand to avoid extrusion with the inner wall of the guide sleeve.

[0018] 2. Through the designed bayonet, telescopic spring and adjusting spring, the mounting plate can be quickly limited and fixed during use, which is convenient for early debugging and avoids the tediousness of frequent disassembly of the motor during the early debugging process.
