They are flexible in movement, easy to operate, and suitable for narrow and complex environments such as coal rock roadways and coal roadways.

[0003] Currently, monorail track laying is typically carried out by workers wearing safety harnesses standing on a workbench, installing the track section by section from the outside in, ensuring its straightness and levelness. The quality and speed of track laying are significantly affected by the tunnel environment and the skill level of the workers, resulting in low efficiency. Furthermore, the process involves the use of large lifting machinery and frontline operation by workers, posing numerous safety hazards. Therefore, there is an urgent need for an automated monorail track laying device that can safely and efficiently complete the track laying work for monorail cranes. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an automatic track-laying device for monorail cranes, which solves the problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An automatic track-laying device for monorails includes a suspension beam that can slide along the length of a guide rail. A first driver is fixed to one side of the suspension beam, and a telescopic arm is fixed to the end of the drive shaft of the first driver and drives the telescopic arm to rise and fall. A second crossbeam is provided on one side of the telescopic arm, and a first lateral driver is fixed on the telescopic arm to drive the first crossbeam to move horizontally in a direction perpendicular to the track. A second driver is fixed on the first crossbeam, and an electromagnetic chuck is fixed to the end of the drive shaft of the second driver and drives the electromagnetic chuck to rise and fall.

[0007] The lower end of the suspension beam is provided with a fixed frame, and the fixed frame is provided with a lifting mounting frame.

A second lateral driver is provided on one side of the mounting frame to push the guide rail to move horizontally on the first pulley assembly. The upper end of the suspension beam is fixed with a track positioning pulley, and the track can be aligned with the track positioning pulley.

[0008] Furthermore, a second pulley assembly is fixed to the upper end of the suspension beam, and the second pulley assembly slides in cooperation with the track along its length.

[0009] Furthermore, a drive rod is provided at the lower end of the suspension beam, with one end of the drive rod hinged to the lower end of the suspension beam and the other end hinged to the monorail crane.

[0010] Furthermore, a third actuator is provided at the lower end of the fixing frame to control the lifting and lowering of the mounting frame.

[0011] Furthermore, the first actuator is fixed to the suspension beam by a retainer and bolts.

[0012] Furthermore, the mounting bracket is equipped with a rolling motor to drive the first pulley assembly to rotate and to make the track slide along its length.

[0013] Furthermore, the number of the first driver, the first lateral driver, the second driver, the third driver, and the second lateral driver is two.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, an automatic track-laying device for a monorail includes a track 1 and a suspension beam 4. A second pulley assembly 12 is fixed to the upper end of the suspension beam 4, and the second pulley assembly 12 slides with the track 1 along its length. A drive rod 11 is provided at the lower end of the suspension beam 4. One end of the drive rod 11 is hinged to the lower end of the suspension beam 4, and the other end is hinged to the monorail crane. Under the drive of the monorail crane, the suspension beam 4 can slide along the length of the guide rail 1.

[0030] A lifting structure is provided below the suspension beam 4, as follows: A first driver 3 is fixed to one side of the suspension beam 4, and a telescopic arm 6 is fixed to the end of the drive shaft of the first driver 3, which can drive the telescopic arm 6 to extend downward to the tunnel floor; A first crossbeam 10 is provided on one side of the telescopic arm 6, and a first transverse driver 7 is fixed on the telescopic arm 6. The first transverse driver 7 drives the first crossbeam 10 to move horizontally in a direction perpendicular to the track. A second driver 8 is fixed on the first crossbeam 10, and an electromagnetic chuck 9 is fixed to the end of the drive shaft of the second driver 8, which can control the lifting and lowering of the electromagnetic chuck 9. The electromagnetic chuck 9 can use magnetic attraction to attract the track, thereby completing the lifting and transfer of the track.

[0031] In this embodiment, the first driver 3 is detachably fixed to the suspension beam 4 by means of a retainer 5 and bolts.

[0032] like Figure 6 The diagram shows the track docking structure of the device. An L-shaped fixing frame is installed at the lower end of the suspension beam 4. A mounting frame is mounted on the fixing frame, and a first pulley assembly 15 is installed on the mounting frame. By controlling the first transverse driver 7, the second driver 8, and the first driver 3, the track can be moved above the first pulley assembly 15. A rolling motor 14 is installed on the mounting frame to drive the first pulley assembly 15 to rotate, allowing the track to slide along its length. A third driver 16 is installed at the lower end of the fixing frame to control the lifting and lowering of the mounting frame, thereby adjusting the vertical position of the track on the first pulley assembly 15. A second transverse driver 13 is installed on one side of the mounting frame, which can push the guide rail to move horizontally on the first pulley assembly 15. A track positioning pulley 2 is fixed at the upper end of the suspension beam 4. The second transverse driver 13, in conjunction with the third driver 16, aligns the track 1 with the track positioning pulley 2 to complete track laying.

[0033] During operation, the first transverse actuator 7 and the second actuator 8 cooperate with each other to move the electromagnetic chuck 9 directly above the pre-placed track on the tunnel floor via a remote control system. The electromagnetic chuck 9 is then activated, using electromagnetism to pick up and firmly grip the track. Next, the first actuator 3 is activated first to lift the telescopic arm 6 upward, thereby raising the track to a certain height. Afterward, the first transverse actuator 7 and the second actuator 8 cooperate with each other to move the electromagnetic chuck 9 directly above the first pulley assembly 15, and slowly place the track into the first pulley assembly 15.

[0034] Next, the rolling motor 14 controls the first roller assembly 15 to rotate, moving the track toward the track positioning pulley 2. During this process, the second horizontal driver 13 is used to make fine adjustments to the track in the horizontal direction, and the third driver 16 is used to make fine adjustments to the track in the vertical direction. After aligning the track with the track positioning pulley 2, the rolling motor 14 continues to control the first pulley assembly 15 to send the track into the position of the track positioning pulley 2. The second horizontal driver 2 and the third driver 16 can ensure the straightness and horizontality of the track.

[0035] It is worth mentioning that in this embodiment, the number of the first driver 3, the first lateral driver 7, the second driver 8, the third driver 16, and the second lateral driver 13 are all two, which can ensure that the track remains stable during transportation. The number of drivers can be added or reduced as needed. The suspension beam, the telescopic arm, and the extension arm all adopt a rectangular structure and are fixedly connected by screws at the connection nodes, thereby ensuring the overall stability and durability. The pulley surfaces on the first pulley assembly and the second pulley group are all covered with rubber material, which increases the resistance between the track and the pulley group and reduces the wear of metal materials during contact.

[0036] In addition, in this embodiment, the first actuator 3, the first lateral actuator 7, the second actuator 8, the third actuator 16, and the second lateral actuator 13 are all hydraulic cylinders. Of course, in some embodiments, they can also be electric push rods or pneumatic cylinders.

[0037] In this embodiment, the provided monorail automatic track laying device employs an electro-hydraulic hybrid control system to provide power to each hydraulic cylinder control component, an electrical control device to power each electrical component, and a remote control system. This allows for remote control of the monorail automatic track laying device's operation or unmanned operation, with the entire operation primarily controlled remotely. This implementation preferably combines a hydraulic control system, an electrical control device, and a remote control system to achieve intelligent and mechanized monorail track laying within tunnels. Of course, those skilled in the art can use other methods to control the operation of the various actuators of the monorail automatic track laying device provided in this embodiment.
