Abstract

The present invention relates to the technical field of hoisting equipment, and specifically to a material transportation gantry hoisting device, which includes a guide rail, a compensation member and a limit assembly. When the gantry moves on the transverse rail, the first compensation rod and the second compensation rod are in a coaxial first state, and the limit assembly can prevent the first compensation rod and the second compensation rod from changing from the first state to the second state. At this time, the first compensation rod and the second compensation rod are in a relatively stable state, and the ends of the first compensation rod and the second compensation rod are simultaneously overlapped on the upper surface of the longitudinal rail. When the gantry moves to the cut-off area of ​​the transverse rail, the first compensation rod and the second compensation rod jointly support the gantry to ensure that the wheels of the gantry will not be in a vacant state, thereby avoiding the situation where different wheels are subjected to excessive stress, and further improving the safety and accuracy of the gantry transporting materials.

Description

Technical Field

[0002] In modern industrial production and logistics management, gantry, as an important material transportation equipment, is widely used in the handling and loading and unloading of large materials. However, with the improvement of production efficiency and the diversification of material types, higher requirements are placed on the operation stability and transportation accuracy of the gantry. In the prior art, the gantry usually needs to transport materials in both the horizontal and vertical directions. In order to meet this demand, many gantry devices adopt a cross-track design. The gantry moves materials from one position to another through the horizontal track.

[0003] By setting the longitudinal track, the transverse track will have a disconnection point. When the gantry moves along the transverse track to the disconnection point, the wheels of the gantry will be off the track, causing the remaining wheels on the track to bear greater stress. This stress concentration will cause the gantry to shake up and down, thereby affecting the operating stability of the entire equipment and the smoothness of transportation. In addition, the gantry is prone to violent vibration in this state, which may also cause secondary shaking or deviation of the material, further reducing the safety and accuracy of transportation, especially for the transportation of precision equipment or fragile materials.

[0031] like Figures 1 to 8 As shown, an embodiment of the present invention provides a material transport gantry hoisting device, which includes a guide rail, a compensation member and a limit assembly.

[0032] The guide rail includes a transverse rail 110 and a longitudinal rail 120, and the transverse rail 110 and the longitudinal rail 120 both have an installation base 130. In the present embodiment, the installation base 130 is a concrete foundation. The height of the transverse rail 110 in the vertical direction is equal to the height of the longitudinal rail 120 in the vertical direction. The transverse rail 110 and the longitudinal rail 120 are arranged perpendicularly, then the transverse rail 110 is arranged in the left-right direction, and the longitudinal rail 120 is arranged in the front-back direction. The horizontal plane where the longitudinal rail 120 is located is below the horizontal plane where the transverse rail 110 is located, then the upper end surface of the installation base 130 of the transverse rail 110 is above the upper end surface of the installation base 130 of the longitudinal rail 120. There is an intersection area between the transverse rail 110 and the longitudinal rail 120, and there is a truncation area in the intersection area of ​​the transverse rail 110. Under the action of the truncation area, the transverse rail 110 is truncated into a first section and a second section, wherein the first section is coaxially arranged with the second section, an end of the first section close to the second section is the first end, and an end of the second section close to the first section is the second end.

[0033] The compensation member includes a first compensation rod 140 and a second compensation rod 150. There are a first end and a second end in the truncation area of ​​the cross rail 110. One end of the first compensation rod 140 is hinged to the first end, and one end of the second compensation rod 150 is hinged to the second end. The first compensation rod 140 and the second compensation rod 150 have a first coaxial state and a second state with an angle. Specifically, when the gantry 160 moves on the cross rail 110, the first compensation rod 140 and the second compensation rod 150 are in the first coaxial state. When the first compensation rod 140 and the second compensation rod 150 are in the first coaxial state, the first compensation rod 140 is coaxial with the first section of the cross rail 110, and the second compensation rod 150 is coaxial with the second section of the cross rail 110. Further, when the first compensation rod 140 and the second compensation rod 150 are in the first coaxial state, the ends of the first compensation rod 140 and the second compensation rod 150 are simultaneously overlapped on the upper surface of the longitudinal rail 120, and the first compensation rod 140 or the second compensation rod 150 no longer forms a cantilever beam. When the gantry 160 moves to the cut-off area of ​​the transverse rail 110, the first compensation rod 140 and the second compensation rod 150 jointly support the gantry 160, ensuring that the wheels of the gantry 160 will not be in the air, thereby avoiding the situation where different wheels are subjected to excessive stress, and further improving the safety and accuracy of the gantry 160 in transporting materials. Furthermore, when the gantry 160 moves on the longitudinal rail 120, the first compensation rod 140 and the second compensation rod 150 are in the second state, then the first compensation rod 140 and the second compensation rod 150 will not hinder the movement of the gantry 160 on the longitudinal rail 120, ensuring that the gantry 160 can run smoothly on the longitudinal rail 120.

[0034] The limiting assembly is used to prevent the first compensation rod 140 and the second compensation rod 150 from changing from the first state to the second state when the gantry 160 moves along the transverse rail 110. The limiting assembly can also remove the obstacle for the first compensation rod 140 and the second compensation rod 150 to change from the first state to the second state when the gantry 160 moves along the longitudinal rail 120. Specifically, under the action of the limiting assembly, when the gantry 160 moves along the transverse rail 110, the first compensation rod 140 and the second compensation rod 150 are in a stable state, reducing the probability of the first compensation rod 140 and the second compensation rod 150 being offset, thereby improving the stability of the first compensation rod 140 and the second compensation rod 150.

[0035] The present invention provides a material transport gantry lifting device. When the gantry 160 is used to transport materials, the gantry 160 can move on the transverse rail 110 or the longitudinal rail 120. When the gantry 160 moves on the transverse rail 110, the first compensation rod 140 and the second compensation rod 150 are in a coaxial first state, and the limit assembly can prevent the first compensation rod 140 and the second compensation rod 150 from changing from the first state to the second state. At this time, the first compensation rod 140 and the second compensation rod 150 are in a relatively stable state, and the ends of the first compensation rod 140 and the second compensation rod 150 are simultaneously overlapped on the upper surface of the longitudinal rail 120. When the gantry 160 moves to the cut-off area of ​​the transverse rail 110, the first compensation rod 140 and the second compensation rod 150 are coaxial. At the same time, the gantry 160 is supported to ensure that the wheels of the gantry 160 will not be in a state of being suspended in the air, thereby avoiding the situation where different wheels are subjected to excessive stress, and further improving the safety and accuracy of the gantry 160 in transporting materials; in addition, when the gantry 160 moves on the longitudinal rail 120, the limit assembly removes the obstacle that the first compensation rod 140 and the second compensation rod 150 are transformed from the first state to the second state, and the movement of the gantry 160 on the longitudinal rail 120 can drive the first compensation rod 140 and the second compensation rod 150 to transform from the first state to the second state, then the first compensation rod 140 and the second compensation rod 150 will not hinder the movement of the gantry 160 on the longitudinal rail 120, thereby improving the stability of the gantry 160 during the process of lifting materials.

[0036] In one embodiment, the limit assembly includes a sensing member and a locking member, the sensing member is used to sense the movement of the gantry 160 on the transverse rail 110 or the longitudinal rail 120, and the sensing member can be used to determine whether the gantry 160 acts on the transverse rail 110 or the longitudinal rail 120.

Specifically, the first locking rod 210 and the second locking rod are both vertically arranged, the first locking rod 210 slides in the vertical direction on the first compensation rod 140, and the second locking rod slides in the vertical direction on the second compensation rod 150. The mounting base 130 of the longitudinal rail 120 is provided with a first locking groove 230 and a second locking groove. When the gantry 160 moves along the transverse rail 110, the first locking rod 210 can be inserted into the first locking groove 230, and the second locking rod can be inserted into the second locking groove. When the first locking rod 210 is inserted into the first locking groove 230, the second locking rod is simultaneously inserted into the second locking groove.

In the initial state, the first return spring is in the original length state. At this time, the lower end of the first locking rod 210 is not inserted into the first locking groove 230. When the gantry 160 moves along the transverse rail 110, the lower end of the first locking rod 210 is inserted into the first locking groove 230. At the same time, the first return spring is stretched. When the gantry 160 moves along the longitudinal rail 120, the first return spring actively resets, and the first return spring pulls the first locking rod 210 out of the first locking groove 230.
