Description

Technical Field

[0001] This utility model belongs to the field of railway long steel rail production and manufacturing technology, specifically relating to a rail transit 100-meter rail freight transport device. Background Technology

[0002] At the long rail manufacturing base, 100-meter-long rails need to be stored, loaded, unloaded, and stacked during operations. Due to the length of the rails, multiple gantry cranes and multiple operators are required to work together during the transfer process, which is inefficient and poses safety hazards.

[0003] Most companies in the industry still use manual operation of gantry cranes, requiring multiple operators. The operator controls an electric hoist via a handheld button box, and each time rails are lifted or unloaded, the operator manually calibrates the rail position using the hoist. Uncontrollable human factors, such as inaccurate positioning, can lead to rail distortion and excessive storage location errors. Furthermore, because operators must stand near the rails while operating the gantry crane, there is a risk of personal injury. Therefore, this utility model proposes a 100-meter rail cargo transport device for rail transit. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides a rail transit 100-meter rail freight transport device to solve the problems mentioned in the background technology.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A rail transit 100-meter rail freight transport device includes a frame and a lifting mechanism installed on the top of the frame. The frame includes two opposing support legs, namely a first gantry crane support leg and a second gantry crane support leg, which are connected by a top crossbeam. The top of the frame is provided with a coding ruler positioning device, which includes a coding ruler laid on the upper surface of the crossbeam and a launch box slidably disposed on the crossbeam. The lifting mechanism includes an electric hoist slidably disposed with the crossbeam, the electric hoist being provided with a hook and a tension sensing device.

[0007] Further tension sensing devices include a tension sensor installed between the electric hoist and the hook.

[0008] Furthermore, a pulley is rotatably connected to the bottom of the launch box 4, and the pulley is slidably connected to the slide rail. The slide rail is fixedly installed on the upper surface of the crossbeam parallel to the encoder ruler.

[0009] Furthermore, connecting frames are installed on both sides of the launch box, namely the first connecting frame and the second connecting frame, which are fixedly connected to the electric hoist.

[0010] The transmitter box further includes a decoder positioned opposite the encoder ruler. The transmitter box also contains a traveling frequency converter, a lifting contactor, and a signal transmitter for sending signals to the upper control console.

[0011] The upper control console is equipped with a display panel and control levers, while the bottom houses the PLC controller and switch.

[0012] Further support feet are equipped with travel rollers at the bottom.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. This utility model uses a coded ruler for positioning and a tension sensor to collect gravity signals for load detection on the rails. It integrates these two technologies with fieldbus control, variable frequency speed control, upper computer monitoring and data management, and PLC control systems to achieve automatic synchronous control of multiple gantry crane electric hoists. Centralized control enables synchronized movement of multiple hoists, ensuring the long rails remain straight during lifting. This device can perform overall loading, unloading, and lateral movement of 100-meter-long rails. One person can operate multiple or all gantry cranes, significantly improving production efficiency and reducing labor costs by enabling centralized lifting and handling of long rails.

[0025] Example 1:

[0026] like Figure 1-4 As shown, a rail transit 100-meter rail freight transport device includes a frame and a lifting mechanism installed on the top of the frame. The frame includes two opposing support legs, namely a first gantry crane support leg 1 and a second gantry crane support leg 8. The support legs are connected by a top crossbeam 2. The top of the frame is provided with a coding ruler positioning device, which includes a coding ruler 9 laid on the upper surface of the crossbeam 2 and a launch box 4 slidably disposed on the crossbeam 2. The lifting mechanism includes an electric hoist 6 slidably disposed with the crossbeam 2, a hook 7 disposed on the electric hoist 6, and a tension sensing device disposed on the electric hoist 6.

[0027] Further tension sensing devices include a tension sensor 21 installed between the electric hoist 6 and the hook 7.

[0028] Furthermore, a pulley 11 is rotatably connected to the bottom of the launch box 4. The pulley 11 is slidably connected to the slide rail 22. The slide rail 22 is fixedly installed on the upper surface of the crossbeam 2 in parallel with the encoder ruler.

[0029] Furthermore, connecting frames are installed on both sides of the launch box 4, namely the first connecting frame 5 and the second connecting frame 10, which are fixedly connected to the electric hoist 6.

[0030] The transmitter box 4 further includes a decoder 12 positioned opposite the encoder ruler 9. The transmitter box 4 also includes a traveling frequency converter 13, a lifting contactor 14, and a signal transmitter 15 for sending signals to the upper control console 16.

[0031] The upper control console 16 is equipped with a display panel 17 and an operating lever 18, and a PLC controller 19 and a switch 20 are installed at its bottom.

[0032] Further support feet are provided with travel rollers 3 at the bottom.

[0033] like Figures 1-4 As shown, the working principle of this device is as follows: First, the operator controls the gantry crane through the PLC controller 19 in the upper control console 16, and controls the lateral movement of the electric hoist 6 through the operating lever 18. During this process, the device uses the encoder 9 for positioning, which is laid on the gantry crane beam 2. When the electric hoist 6 moves, it drives the transmitter box 4 to move synchronously. The signal generated by the relative position sensing between the transmitter box 4 and the encoder 9 is decoded by the decoder 12 and sent to the upper control console 16 for processing. When lifting operations are performed, the tension sensor 21 detects the load on the rail. By integrating these two technologies with fieldbus control technology, variable frequency speed regulation transmission, upper computer monitoring and data management, and PLC control system, automatic synchronous control of multiple gantry crane electric hoists 6 can be achieved. Through centralized control, the synchronous movement of multiple cranes is achieved to ensure that the long rails remain in a straight state during the lifting process. This system can perform overall loading, unloading, and lateral displacement lifting of 100-meter-long rails, allowing one person to operate multiple or all gantry cranes to achieve centralized lifting and transportation of long rails.
