Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a monorail crane. Background Art

[0002] A crane is an electromechanical device used for vertical lifting or vertical lifting and horizontal movement of heavy objects. Cranes use a lifting hook or other lifting mechanism to lift or lift and move heavy objects. The crane's operation generally includes the following steps: lifting, operating, lowering, and returning to the original position. The lifting mechanism uses the lifting mechanism to lift the object from the retrieval location. The lifting mechanism then moves the object through the operating, slewing, or luffing mechanism. The object is then lowered to the designated location and returned to its original position.

[0003] Patent publication number CN207524836U discloses an electric monorail crane, comprising two frames fixed to a work base. The monorail is positioned on the lower surfaces of the two frames, perpendicular to the crossbeams on the two frames. An electric hoist is mounted on the monorail, and a suspension controller is located below the hoist to control its movement along the monorail. A support frame is fixed above one or both of the frames, and a stay cable is mounted on the support frame. One end of the stay cable is positioned at multiple locations on the monorail. This simple structure allows for easy installation and minimizes space. The stay cable and other structures ensure the crane's safety.

[0004] Although the above-mentioned electric monorail crane can solve the corresponding technical problems, it has a simple structure and single function. The electric hoist only realizes the transportation of materials along the X-axis and Z-axis, and it is inconvenient to match it with a single-beam assembly to realize the rotation of materials along the Y-axis, thereby reducing the scope of application of the electric monorail crane. Utility Model Content

The driving mechanism, the second winch and the electric push rod are electrically connected to the control mechanism respectively, and the cables of the driving mechanism, the second winch, the electric push rod and the control mechanism all pass through the drag chain and are electrically connected to the external power supply.

[0025] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 6 As shown, a monorail crane includes a monorail trolley 100 movably arranged on the track, a hoisting mechanism 200 for vertically lifting materials or single-beam components, and a locking mechanism 300 for use with ears of the single-beam components. The hoisting mechanism 200 and the locking mechanism 300 are both arranged at the bottom of the monorail trolley 100; the locking mechanism 300 includes an end beam body 310 arranged below the track and used to bear the entire deadweight of the hoisting mechanism 200 and the load from the hoisting mechanism 200 or the single-beam components. The end beam body 310 is a U-shaped structure. Positioning assemblies 320 for locking the single-beam components are provided on both sides of the bottom of the end beam body 310, and a guide assembly 330 for guiding the ears of the single-beam components is provided on one side of the end beam body 310.

[0028] Among them, the monorail trolley 100 includes a traveling mechanism 110 movably arranged at the bottom of the track and a cable protection mechanism 130 arranged on the side of the track. The traveling mechanism 110 is installed on the end beam 310. The traveling mechanism 110 is installed with a driving mechanism 120 for driving the traveling mechanism 110 to move along the length direction of the track. The cable protection mechanism 130 is used to protect the cables of the monorail trolley 100, the lifting mechanism 200 and the locking mechanism 300. A first winch 140 for winding or releasing the cables is installed on one side of the end beam 310. By starting the driving mechanism 120, a power source for operation can be provided for the traveling mechanism 110, so that the traveling mechanism 110 can run along the length direction of the track to realize the handling operation of materials or single beam components. By starting the first winch 140, the cable can be wound or released, and its rotation direction and rotation speed will change with the changes in the rotation direction and rotation speed of the second winch 210.

[0029] Among them, the cable protection mechanism 130 includes a bracket 131 installed on one side of the track, and the inner cavity of the bracket 131 is provided with a drag chain 132. One end of the drag chain 132 is fixedly connected to the inner wall surface of the bracket 131, and the other end of the drag chain 132 is fixedly connected to the top of the end beam body 310. The bracket 131 can provide a moving space for the drag chain 132 and the cable, and the drag chain 132 can pull and protect the cable, effectively preventing the cables from interfering with or entangled with each other.

[0030] Among them, the lifting mechanism 200 includes a second winch 210 installed inside the end beam body 310, and a lifting ring assembly 220 is lifted below the second winch 210 through a wire rope. By starting the second winch 210, the wire rope can be wound or released, thereby lifting or lowering the lifting ring assembly 220.

[0031] Among them, the suspension ring assembly 220 includes a T-shaped rod 221. Rope winding wheels 222 used in cooperation with steel wire ropes are installed at both ends of the T-shaped rod 221. A pin hole adapted to the pin member of the single beam assembly is formed on the T-shaped rod 221. Through the pin hole, materials can be hoisted on the T-shaped rod 221, and it is also convenient for subsequent assembly with the single beam assembly.

[0032] Among them, the positioning assembly 320 includes a slot seat 321 fixedly connected to the bottom of the end beam body 310 and for inserting the earpiece of the single beam assembly. A housing 322 is fixedly connected to one side of the slot seat 321. An electric push rod 323 is installed in the inner cavity of the housing 322. A pin shaft used in cooperation with the earpiece of the single beam assembly is fixedly connected to the output end of the electric push rod 323. By starting the electric push rod 323, the pin shaft can be driven to extend or retract from the housing 322, and the single beam assembly can be locked below the hoisting mechanism 200, thereby forming a combined crane, which helps to improve the practicability of the single-rail crane.

[0033] Among them, the guiding assembly 330 includes two brackets 331 symmetrically and fixedly connected to one side of the end beam body 310 and used in cooperation with the earpiece of the single beam assembly. The brackets 331 and the slot seat 321 are arranged in one-to-one correspondence. The slot seat 321 is located between the housing 322 and the brackets 331. A guide groove body 332 used in cooperation with the guide wheel of the single beam assembly is fixedly connected to the bottom of the bracket 331. The side and the bottom of the guide groove body 332 facing the T-shaped rod 221 are both of an open structure. When the earpiece of the single beam assembly is aligned with the slot seat 321 and placed in the inner cavity of the slot seat 321, the guide wheel of the single beam assembly can be slidably connected to the inner wall surface of the guide groove body 332, thereby eliminating the swing of the single beam assembly during the lifting process, which helps to improve the stability of the single beam assembly during the lifting process.

[0034] Among them, a U-shaped mounting plate (400) is fixedly connected to one side of the second winch (210). A control mechanism (500) is installed in the inner cavity of the mounting plate (400). The driving mechanism (120), the second winch (210), and the electric push rod (323) are respectively electrically connected to the control mechanism (500). The cables of the driving mechanism (120), the second winch (210), the electric push rod (323), and the control mechanism (500) all penetrate through the drag chain (132) and are electrically connected to an external power supply. The working states or parameters of the driving mechanism (120), the second winch (210), and the electric push rod (323) can be adjusted through the control mechanism (500) to achieve the effect of automatic operation. The control mechanism (500) can be composed of a PLC control box and a controller installed inside the control box.

[0035] The working principle of the present invention is as follows: by starting the second hoist 210 to release the wire rope, the eye assembly 220 is lowered to the required position, the material is hung on the pin hole of the T-bar 221, and the second hoist 210 is started again to wind the wire rope, the material can be lifted to the required position, and the traveling mechanism 110 is driven to move on the track by starting the driving mechanism 120. The traveling mechanism 110 drives the locking mechanism 300, the hoisting mechanism 200 and the material to move synchronously along the length direction of the track until the required position, thereby realizing the material transfer operation in the X-axis (i.e., along the track direction) and the Z-axis direction (i.e., the vertical direction); according to actual use requirements, the second hoist 210 is started to release the wire rope, so that the eye assembly 220 is lowered to the storage height of the single-beam assembly, and the single-beam assembly is connected to the eye assembly 220 through the connector, and then The second winch 210 is started to perform the wire rope winding operation, and the lifting ring assembly 220 drives the single beam assembly to rise. When it moves to a certain height, the guide wheel of the single beam assembly slides to the inner cavity of the guide groove body 332, and the ear piece of the single beam is inserted into the inner cavity of the slot seat 321. At this time, the electric push rod 323 is started, so that the output end of the electric push rod 323 drives the pin to extend out of the shell 322 and insert into the inner cavity of the ear piece, thereby locking the single beam assembly under the track, so that the monorail crane can be used in combination with the single beam assembly. At this time, the lifting mechanism 200 can be used to realize the Y-axis (i.e., along the single beam direction) transfer operation of the single beam assembly, and the transverse trolley on the single beam assembly can be used to realize the X-axis (i.e., along the track direction) and Z-axis (i.e., vertical direction) transfer operation of the material, so as to realize the material transfer in three dimensions along the X, Y, and Z axes, thereby improving the use convenience and applicability of the monorail crane.

[0036] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
