Description

Technical field:

[0001] The utility model relates to the field of pipe pile production equipment, in particular to a pipe pile transport device. Background technology:

[0002] Prestressed high-strength concrete pipe piles are made using the pre-stressed centrifugal forming process and steam-cured to form a hollow cylindrical concrete prefabricated component. In the construction field, they are driven into the soil by a pile driver as a foundation.

[0003] The production process of pipe piles needs to go through the steps of rolling welding, grouting, centrifugal forming, primary steaming, secondary steaming, cutting, etc. Due to the long length of pipe piles, the transportation of their molds and products during the production process is usually carried out by overhead cranes. However, due to the limited space in the production site, the number of overhead cranes that can be arranged is limited, and the overhead crane can only transport one pipe pile or pipe pile mold at a time, resulting in low production efficiency. The existing solution is to arrange a certain number of transfer tracks in the production site, and multiple transfer pulleys are arranged on the transfer tracks. Multiple products can be transported at the same time through multiple pulleys to improve the transfer efficiency between each process. However, most of the existing tracks are arranged on the ground, and the driving power source is set on the pulley, resulting in uneven road surface at the production site and inconvenient passage of engineering vehicles such as forklifts. Utility model content:

[0004] The utility model aims to provide a pipe pile transporting device to solve the problems existing in the prior art.

[0005] The utility model is implemented by the following technical scheme: a pipe pile transport device, including rails, a flat track car and a driving mechanism, two parallel embedded rails are fixed on the ground, a trench is opened at a certain interval on the ground between the two rails, the driving mechanism is fixedly installed in the trench, the bottom surface of the flat track car is in active contact with the friction wheel of the driving mechanism, and a cover plate level with the ground is provided on the top surface of the trench, and an opening is opened on the cover plate.

[0006] Furthermore, the driving mechanism includes a fixed bracket, a lifting bracket, a friction wheel, a driving motor and an electric telescopic cylinder. The fixed bracket is fixedly installed in the trench, one end of the fixed bracket is hinged to the lifting bracket, the other end of the fixed bracket is hinged to the fixed end of the electric telescopic cylinder, and the telescopic end of the electric telescopic cylinder is hinged to the lifting bracket; a friction wheel is rotatably provided on one side of the lifting bracket close to the electric telescopic cylinder, and a driving motor is fixedly installed on the other side of the lifting bracket, and the output shaft of the driving motor is transmission-connected to the friction wheel.

[0007] Furthermore, the driving mechanism also includes a worm reducer, the output shaft of the driving motor is connected to the input end of the worm reducer, and the output shaft of the worm reducer is connected to the friction wheel through a chain drive.

[0008] Furthermore, it also includes a speed sensor, which is fixedly installed through the cover plate. A row of several sensing protrusions are fixedly provided at the bottom of the flat track vehicle at positions corresponding to the speed sensor, and the distance between every two sensing protrusions is equal.

[0009] The advantages of the utility model are as follows: the ground is leveled by means of an embedded track and a driving mechanism placed in the trench; the friction wheels in the driving mechanism can be raised and lowered by the drive of an electric telescopic cylinder; when a flatbed rail vehicle passes by, the wheels are raised to contact the flatbed rail vehicle to provide power for the flatbed rail vehicle; when there is no flatbed rail vehicle, the wheels are lowered, which will not affect the passage of on-site engineering vehicles; multiple flatbed rail vehicles can be run on the track at the same time, which reduces the time for transfer between various processes and improves transportation efficiency.

[0016] like Figure 1As shown: a pipe pile transport device, which includes a track 1, a flat track vehicle 2 and a driving mechanism 3, two parallel embedded tracks 1 are fixed on the ground, the track 1 is embedded below the ground, the top surface of the track 1 is flush with the ground, a trench is opened at a certain distance on the ground between the two tracks 1, and a driving mechanism 3 is fixedly installed in the trench, and the driving mechanism 3 is designed and arranged along the track 1 according to needs. Since a larger torque is required when the flat track vehicle 2 stops and starts, multiple groups are provided at the positions where the flat track vehicle 2 needs to start and stop, which are used to drive the flat track vehicle 2 to start and stop at the same time, and the positions where the middle flat track vehicle 2 needs to slide at a uniform speed can be arranged at a longer interval; a cover plate 4 flush with the ground is provided on the top surface of the trench, and an opening is provided on the cover plate 4, and the opening is used to pass the friction wheel 303 extending out of the trench so that the friction wheel 303 contacts the bottom surface of the flat track vehicle 2; when no flat track vehicle 2 passes, the track 1 is flush with the ground, the trench cover is provided with a cover plate 4, and nearby pedestrians and engineering vehicles can pass normally.

[0017] like Figure 2 As shown: the driving mechanism 3 includes a fixed bracket 301, a lifting bracket 302, a friction wheel 303, a driving motor 304 and an electric telescopic cylinder 305. The fixed bracket 301 is fixedly installed in the trench. One end of the fixed bracket 301 is hinged to the lifting bracket 302, and the other end of the fixed bracket 301 is hinged to the fixed end of the electric telescopic cylinder 305. The telescopic end of the electric telescopic cylinder 305 is hinged to the lifting bracket 302. Through the telescopic movement of the electric telescopic cylinder 305, the lifting bracket 302 is driven to move up and down reciprocatingly at one end of the electric telescopic cylinder 305. The friction wheel 303 is rotatably provided on one side of the lifting bracket 302 close to the electric telescopic cylinder 305. The bottom surface of the flat track car 2 is in active contact with the friction wheel 303 of the driving mechanism 3. The outer edge of the friction wheel 303 that contacts the flat track car 2 is made of existing rubber material or polyurethane material, which can increase the friction force. When the electric telescopic cylinder 305 is extended, the friction wheel 303 is rotated to the bottom surface of the flat track car 2. When the lifting bracket 302 is long, the lifting bracket 302 is lifted up, and part of the outer edge of the friction wheel 303 extends out of the ditch and is higher than the ground plane, so as to contact the bottom surface of the flat track vehicle 2; when the electric telescopic cylinder 305 is shortened, the lifting bracket 302 descends, and the friction wheel 303 is retracted into the ditch, below the ground plane, which will not affect the passage of ground engineering vehicles; a driving motor 304 is fixedly installed on the other side of the lifting bracket 302, and the driving mechanism 3 also includes a worm reducer 306, and the output shaft of the driving motor 304 is connected to the input end of the worm reducer 306, and the output shaft of the worm reducer 306 is connected to the friction wheel 303 through a chain drive. The worm reducer 306 can increase the torque so that the wheel end torque of the friction wheel 303 can achieve the effect of driving the flat track vehicle 2 to move. By controlling the forward and reverse rotation and speed of the driving motor 304, the forward and reverse rotation and speed of the friction wheel 303 can be controlled, thereby controlling the walking, stopping, acceleration and deceleration of the flat track vehicle 2.

[0018] like Figure 3 As shown: it also includes a speed sensor 5, which is fixedly installed through the cover plate 4. A row of several sensing bumps 6 are fixedly provided at the bottom of the flatbed rail vehicle 2 corresponding to the speed sensor 5, and the distance between every two sensing bumps 6 is equal. The speed sensor 5 is an electromagnetic speed sensor, which generates a periodic signal by detecting the sensing bumps 6, and obtains the corresponding speed of the flatbed rail vehicle 2 according to the frequency of the periodic signal.

[0019] Working principle: when the flatbed rail vehicle 2 passes over the driving mechanism 3, when the speed sensor 5 senses the upper sensing protrusion 6, the electric telescopic cylinder 305 extends to lift the lifting bracket 302, so that the friction wheel 303 passes through the opening on the cover plate 4 and contacts the bottom surface of the flatbed rail vehicle 2, and at the same time, the driving motor 304 is started to drive the friction wheel 303 to rotate, and the friction wheel 303 transfers kinetic energy to the flatbed rail vehicle 2 to drive the flatbed rail vehicle 2 to move; through the speed sensor 5, the current speed of the flatbed rail vehicle 2 can be obtained. When the vehicle speed is lower than the set speed range or needs to be started, the driving motor 304 is controlled to rotate forward, and the friction wheel 303 is accelerated to drive the flatbed rail vehicle 2 forward to accelerate; when the vehicle speed is within the set range, the friction wheel 303 is controlled to rotate at a uniform speed to keep the flatbed rail vehicle 2 passing at a uniform speed; when the vehicle speed is higher than the set range or needs to stop, the friction wheel 303 is decelerated or rotated in the reverse direction to control the flatbed rail vehicle 2 to decelerate or stop.
