Description

Technical Field

[0001] The present invention relates to the technical field of monorail cranes, and in particular to a monorail crane double-rail connection and switching system and a use method thereof. Background Art

[0002] Monorail crane is a commonly used transportation equipment in coal mines. It is often used for installation and withdrawal of coal mining teams at the working face in coal mines due to its strong maneuverability, fast running speed, large cargo capacity, safety and reliability.

[0003] With the development of monorail crane technology, the load capacity of monorail crane is gradually increasing, and the maximum load capacity of monorail crane is 50 tons. However, it still cannot meet the heavy-weight transportation needs of some mines. Therefore, the technology of two monorail cranes in parallel can realize the transportation of up to 100 tons of cargo. However, after the two monorail crane tracks are switched at the switch, the tracks intersect and need to be switched. The monorail crane is different from the ordinary ground track. The track of the monorail crane is hanging type, and the intersection must be switched. There is no such switching solution in the current monorail transportation technology. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a single-rail hanging double-rail connection switching system and a use method thereof.

[0005] The present invention is achieved through the following technical scheme, which provides a single-rail hanging double-rail connection switching system, including two parallel tracks, wherein the tracks include an input rail, and a first output rail and a second output rail connected by a switch, wherein the second output rail of one track intersects with the first output rail of the other track and a switching mechanism is arranged at the intersection, wherein the switching mechanism includes a fixed frame and a switching rail located below the fixed frame, wherein the switching rail is hinged to the fixed frame through a vertical rotating shaft, wherein the first output rail at the intersection is provided with a first docking interface matched with the switching rail, and the second output rail at the intersection is provided with a second docking interface matched with the switching rail, and the switching mechanism also includes a driving mechanism for driving the switching rail to swing between the first docking interface and the second docking interface.

[0006] In this scheme, two monorail cranes are moved side by side through two tracks, track switching is achieved through switches, and switching between cross tracks after track switching is achieved through a reversing device.

[0007] As an optimization, the driving mechanism includes a reversing cylinder, one end of which is hinged to the fixing frame, and the other end of which is hinged to the reversing rail. The reversing cylinder in this solution realizes the swinging drive of the reversing rail.

[0008] As an optimization, a connecting frame is fixedly connected to the reversing rail, and the other end of the reversing cylinder is hinged to the connecting frame. The connecting frame in this solution realizes the connection between the reversing cylinder and the reversing rail.

[0009] As an optimization, the connecting frame includes a vertical plate fixed to the upper end of the reversing rail and a horizontal plate fixed to the upper end of the vertical plate, and the horizontal plate is located above the fixing frame. In this solution, when the reversing rail stops at two reversing positions, the horizontal plate can be located above the fixing frame, so if the reversing rail falls, the horizontal plate can provide support to prevent the reversing rail from falling and injuring people.

[0010] As an optimization, both ends of the reversing rail are fixed with connecting frames. In this solution, the connecting frames are arranged at both ends. On the one hand, it can adapt to the installation conditions on site, facilitate the connection of the reversing cylinder with any connecting frame, and facilitate on-site arrangement. On the other hand, the two connecting frames improve the support effect of the reversing rail after falling.

[0011] As an optimization, a stopper is fixedly connected to the lower end surface of the reversing rail, and a limit baffle is fixedly connected to the lower end surface of the end of the second output rail near the second docking interface and the lower end surface of the end of the first output rail near the first docking interface, and one end of the limit baffle extends below the reversing rail. In this solution, after the reversing rail is completed and in place, the stopper hits the limit baffle to achieve its positioning function.

[0012] As an optimization, the lower end surfaces of both ends of the reversing rail are provided with processing planes, and the stopper is fixedly connected to the processing planes, thereby improving the connection strength of the stopper, and the space occupied by the stopper is changed upwards, which does not affect the normal operation of the monorail crane.

[0013] As an optimization, the lower end surface of the end of the second output rail close to the second docking interface and the lower end surface of the end of the first output rail close to the first docking interface are both provided with a processing plane, and the limit baffle is fixedly connected to the processing plane. This improves the connection strength of the limit baffle, and the space occupied by the limit baffle changes upward without affecting the normal operation of the monorail crane.

[0014] As an optimization, the first output rail is coaxial with the input rail, and the two first output rails are parallel.

[0015] A method for using a monorail hanging double-rail connection switching system comprises the following steps: a. Two monorail cranes run on two tracks respectively, and two switches are used to achieve synchronous track switching of the two tracks; b. When two monorail cranes are running on the two first output rails, the reversing rails are swung to make the reversing rails docked on the first pair of interfaces, thus achieving the integrity of the first output rails at the intersection; c. When two monorail cranes are running on the two second output rails, the reversing rails are swung to make the reversing rails docked on the second docking interface to achieve the integrity of the second output rails at the intersection.

[0016] The beneficial effects of the present invention are as follows: a monorail crane double-track connection switching system and a method of use of the present invention can realize the side-by-side movement of two monorail cranes, realize track switching through a switch, and realize switching between cross tracks after track switching through a switching device, thereby increasing the load capacity of the monorail crane in the tunnel and improving the transportation capacity.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figures 1 to 8 As shown, a monorail crane double-rail connection and switching system of the present invention includes two parallel rails, and a monorail crane system is installed on each of the two rails. The heights of the two rails are consistent, or there is a slight height difference, and the rails are fixed on the top surface of the tunnel.

[0022] like Figure 1 As shown, the second output rail 5 of one track intersects with the first output rail 4 of the other track, and a reversing mechanism 1 is arranged at the intersection.

The first output rail 4 and the second output rail 5 are both connected to the fixing frame 11 to improve the bearing capacity of the first output rail 4 and the second output rail 5.

[0025] The driving mechanism includes a reversing cylinder 14, which is arranged above the fixed frame 11, one end of the reversing cylinder 14 is hinged to the fixed frame 11, and the other end is hinged to the reversing rail 12.
