Description

Technical Field

[0001] This utility model relates to the field of crane support technology, and in particular to a gimbal support for a gantry crane. Background Technology

[0002] The pan-tilt bracket of a gantry crane is a device specifically designed to install and secure monitoring equipment such as laser scanners and cameras. Its core function is to provide stable support for these devices during crane operation, ensuring that the equipment position remains accurate at all times. This guarantees the accuracy of material scanning, ship-shaped scanning, and other monitoring tasks, ultimately effectively assisting operators in completing hoisting and other operational processes.

[0003] For example, patent CN216549294U describes a pantograph support for a gantry crane, comprising a main mounting plate, support plates, a laser scanner, and a first drive assembly. The main mounting plate is fixedly connected to the crane. Two support plates are fixedly connected parallel to each other at the bottom of the main mounting plate. The laser scanner is positioned between the two support plates. The first drive assembly is located on the end face of one support plate opposite to the laser scanner and is drively connected to the laser scanner to drive its rotation. The rotation axis is parallel to the main mounting plate. By driving the laser scanner to rotate through the first drive assembly, the scannable area of ​​the laser scanner is increased, expanding the field of view. This allows the gantry crane to perform omnidirectional material and ship-shaped scanning, improving the scanning accuracy of the gantry crane. This enables precise control of the gantry crane's pantograph support operation, thereby obtaining accurate point cloud data from all directions and obtaining accurate material or ship-shaped data.

[0004] However, the above-mentioned patents still have some shortcomings in use. For example, after the gantry crane is used for loading and unloading operations at the port, the scanners and other equipment installed on the gimbal bracket are still exposed to the outside. The wind erosion and salt spray corrosion will significantly affect the performance and life of the scanners and other equipment. In addition, the commonly used protective structure that uses two outer covers to form a closed cavity cannot effectively prevent cold and humid air from entering through the contact gaps. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the prior art, after the loading and unloading operations of gantry cranes in ports, the equipment such as scanners installed on the gimbal bracket are still exposed to the outside, and the wind erosion and salt spray corrosion will significantly affect the performance and life of the scanners and other equipment. In addition, the commonly used protective structure that uses two outer covers to form a closed cavity cannot effectively prevent humid and cold air from entering through the contact gaps. Therefore, a gimbal bracket for gantry cranes is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gantry crane's pantograph support includes a support body. Two protective components are rotatably connected to the bottom of the support body. Each protective component has a movable component fixedly connected to both ends. Pressure boosting components are fixed on both outer walls of the support body. The movable end of each pressure boosting component is fixedly connected to the movable end of the movable component on the same side. A drive component is fixed on the bottom surface of the support body. The drive component and the two protective components are driven by gears.

[0008] The protective assembly includes a first rotating shaft, with a first mounting base rotatably connected to both ends of the first rotating shaft. Each first mounting base is fixedly connected to the side wall of the support body. A protective cover is fixedly connected to the side wall of the first rotating shaft. The protective cover has an overall L-shaped plate structure. A sealing mechanism is fixedly connected to both sides of each protective cover. The output end of the pressurization assembly is connected to the sealing mechanism on the same side through a pipe.

[0009] Preferably, the bracket body includes a main mounting plate and two support plates fixed to the bottom surface of the main mounting plate. A steering mechanism is rotatably connected between the side walls of the two support plates, and a scanner is fixedly connected to the steering mechanism.

[0010] Preferably, the sealing mechanism includes two sealing blocks fixedly connected to one side of the protective cover. Each of the two sealing blocks has a sealing airbag fixedly connected to its adjacent sidewall. The two sealing airbags are connected through a horizontal tube. A first connecting pipe is fixedly connected to the sidewall of the outermost sealing block. The first connecting pipe is connected to the output end of the pressurization component through a pipe.

[0011] Preferably, the drive assembly includes a dual-head motor fixedly connected to the bottom surface of the main mounting plate, two second mounting seats, and a housing. The dual-head motor and the two second mounting seats are all disposed inside the housing. A second rotating shaft is rotatably connected to each of the second mounting seats. One end of each of the two second rotating shafts is fixedly connected to the two output shafts of the dual-head motor, and the other end of each of the second rotating shafts is fixedly connected to a second bevel gear. A first bevel gear is fixedly connected to the side wall of each of the first rotating shafts at the position corresponding to the second bevel gear. The second bevel gear meshes with the corresponding first bevel gear for transmission. The first rotating shaft passes through the housing.

[0012] Preferably, the movable component includes a threaded rod rotatably connected to the side wall of the first mounting base and a plurality of guide rods fixedly connected to the side wall of the first mounting base. One end of the plurality of guide rods is fixedly connected to a limiting plate. One end of the threaded rod is rotatably connected to the limiting plate, and the other end of the threaded rod is fixedly connected to a first rotating shaft. A threaded block is threadedly connected to the side wall of the threaded rod. The threaded block is slidably connected to the plurality of guide rods. The threaded block is fixedly connected to the movable end of the pressurizing component through a plurality of abutments.

[0013] Preferably, the threaded rods at both ends of the same first rotating shaft have opposite thread directions, and the threaded rods at the same end of two first rotating shafts have opposite thread directions.

[0014] Preferably, the pressurization assembly includes extension frames fixedly connected to both sides of the support body. Each extension frame is fixedly connected to a piston cylinder at the position corresponding to the moving component. Each piston cylinder is fixedly connected to a connecting plate at its movable end. Each connecting plate is fixed to a threaded block by multiple push rods. One end of the rodless chamber of each piston cylinder is fixedly connected to a second connecting pipe. The second connecting pipe is connected to the first connecting pipe through a pipeline.

[0015] Preferably, the contact seam between the two protective covers after they are closed is Z-shaped, and the contact surfaces of the two protective covers are both elastic sealing gaskets.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting up protective and driving components, the dual-head motor drives the two first rotating shafts to rotate in opposite directions through the meshing transmission of the first and second bevel gears. The two protective covers are closed to prevent the electronic components and circuits of the scanner and other equipment from getting damp, which could lead to oxidation and corrosion damage.

[0018] 2. By setting up a moving component, a pressure component, and a sealing structure, the rotation of the first rotating shaft can drive the threaded rod to rotate, which in turn drives the threaded block to move horizontally. When the threaded block moves toward the connecting plate, the connecting plate compresses the piston cylinder through the abutment rod. The piston cylinder further transmits the increased pressure to the inside of the sealing airbag through the second connecting pipe and the first connecting pipe, causing it to expand, thereby achieving a secondary seal at the contact seam between the protective cover and the support body.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figure 1 - Figure 4 A gantry crane's gimbal support includes a support body 1. Two protective components 2 are rotatably connected to the bottom of the support body 1 to protect monitoring equipment installed on the support body 1. Each protective component 2 has a movable component 3 fixedly connected to both ends. Pressure boosting components 4 are fixed on the outer walls of both sides of the support body 1. The movable end of each pressure boosting component 4 is fixedly connected to the movable end of the movable component 3 on the same side. A drive component 5 is fixed on the bottom surface of the support body 1. The drive component 5 is transmitted to the two protective components 2 through gears. The opening and closing of the two protective components 2 can be controlled by the drive component 5.

[0030] The protective component 2 includes a first rotating shaft 21, with first mounting seats 22 rotatably connected to both ends of the first rotating shaft 21. Each first mounting seat 22 is fixedly connected to the side wall of the support body 1. A protective cover 23 is fixedly connected to the side wall of the first rotating shaft 21. The protective cover 23 has an overall L-shaped plate structure. A sealing mechanism 24 is fixedly connected to both sides of each protective cover 23. The output end of the pressurizing component 4 is connected to the sealing mechanism 24 on the same side through a pipe. When the protective component 2 is opened and closed, the rotation of the first rotating shaft 21 can drive the moving component 3 to move and squeeze the pressurizing component 4, so that the pressurizing component 4 pressurizes the inside of the sealing mechanism 24 and causes it to expand, thereby achieving the sealing of the contact seam between the protective cover 23 and the support body 1.

[0031] The main body of the bracket 1 includes a main mounting plate 11 and two support plates 12 fixed to the bottom surface of the main mounting plate 11. A steering mechanism 13 is rotatably connected between the side walls of the two support plates 12. A scanner 14 is fixedly connected to the steering mechanism 13. The steering mechanism 13 is driven by two motors to rotate and adjust the scanner 14 along the Z-axis and X-axis respectively. This has been fully disclosed in the prior art and will not be described in detail here.

[0032] Reference Figure 4 and Figure 5 The sealing mechanism 24 includes two sealing blocks 241 fixedly connected to one side of the protective cover 23. The support plate 12 can be inserted between the two sealing blocks 241 to form a primary seal, and the contact cross section between the protective cover 23 and the support plate 12 is C-shaped, which prolongs the air diffusion path and prevents humid air from entering directly. Sealing airbags 242 are fixedly connected to the adjacent side walls of the two sealing blocks 241. The two sealing airbags 242 are connected through a horizontal pipe 243. A first connecting pipe 244 is fixedly connected to the side wall of the outermost sealing block 241. The first connecting pipe 244 is connected to the output end of the pressurizing component 4 through a pipe. The pressurizing component 4 pressurizes the inside of the sealing airbag 242, thereby performing a secondary seal on the C-shaped contact seam and improving the sealing effect.

[0033] Reference Figure 6The drive assembly 5 includes a dual-head motor 51 fixedly connected to the bottom surface of the main mounting plate 11, two second mounting seats 52, and a housing 55. The dual-head motor 51 and the two second mounting seats 52 are all located inside the housing 55. A second rotating shaft 53 is rotatably connected to each second mounting seat 52. One end of each second rotating shaft 53 is fixedly connected to the two output shafts of the dual-head motor 51, and the other end of each second rotating shaft 53 is fixedly connected to a second bevel gear 54. A first bevel gear 25 is fixedly connected to the side wall of each first rotating shaft 21 at the position corresponding to the second bevel gear 54. The second bevel gear 54 meshes with the corresponding first bevel gear 25 for transmission. The first rotating shaft 21 passes through the housing 55. Through the meshing transmission of the first bevel gear 25 and the second bevel gear 54, the dual-head motor 51 drives the two first rotating shafts 21 to rotate in opposite directions, thereby controlling the opening and closing of the two protective covers 23.

[0034] Reference Figure 7 The movable component 3 includes a threaded rod 31 rotatably connected to the side wall of the first mounting base 22 and multiple guide rods 32 fixedly connected to the side wall of the first mounting base 22. One end of the multiple guide rods 32 is fixedly connected to a limiting plate 33. One end of the threaded rod 31 is rotatably connected to the limiting plate 33, and the other end of the threaded rod 31 is fixedly connected to the first rotating shaft 21. When the first rotating shaft 21 rotates, it drives the threaded rod 31 to rotate. A threaded block 34 is threadedly connected to the side wall of the threaded rod 31. The threaded block 34 is slidably connected to the multiple guide rods 32, so that the rotation of the threaded rod 31 can drive the threaded block 34 to translate. The threaded block 34 is fixedly connected to the movable end of the pressure boosting component 4 through multiple abutments 35. The translation of the threaded block 34 squeezes the pressure boosting component 4, and the pressure boosting component 4 further applies the increased pressure to the sealing mechanism 24.

[0035] The threads of the threaded rods 31 at both ends of the same first rotating shaft 21 have opposite directions of rotation, and the rotation directions of the threaded rods 31 at both ends of the same first rotating shaft 21 are the same. By setting opposite threads, the two threaded blocks 34 can move closer or further away from each other synchronously. The threads of the threaded rods 31 at the same end of the two first rotating shafts 21 have opposite directions of rotation, and the rotation directions of the threaded rods 31 at the same end of the two first rotating shafts 21 are opposite. By setting opposite threads, the two threaded blocks 34 can move in the same direction.

[0036] The pressurization assembly 4 includes extension frames 41 fixedly connected to both sides of the support body 1. Each extension frame 41 is fixedly connected to a piston cylinder 42 at the position corresponding to the moving assembly 3. Each piston cylinder 42 is fixedly connected to a connecting plate 43 at its movable end. Each connecting plate 43 is fixed to a threaded block 34 by multiple push rods 35. One end of the rodless chamber of each piston cylinder 42 is fixedly connected to a second connecting pipe 44. The second connecting pipe 44 is connected to the first connecting pipe 244 through a pipe. When the threaded block 34 moves toward the connecting plate 43, the push rod 35 causes the connecting plate 43 to compress the piston cylinder 42. The piston cylinder 42 further transmits the increased pressure to the inside of the sealing airbag 242 through the second connecting pipe 44 and the first connecting pipe 244.

[0037] Reference Figure 8 The contact seam of the two protective covers 23 after they are closed is Z-shaped. Both protective covers 23 have elastic sealing gaskets on their contact surfaces. The contact surfaces of the two protective covers 23 are tightly pressed together by rotation and pressing.

[0038] In this utility model, the steering mechanism 13 at the bottom of the main mounting plate 11 is driven by two motors to realize the rotation and orientation adjustment of the scanner 14 along the Z-axis and X-axis respectively. The scanner 14 is used to scan ship shapes, materials, etc. After use, due to the humid environment of the gantry crane in the port, the open gimbal support structure is prone to moisture damage to the electronic components and circuits of the scanner 14 and other equipment installed on it, which can lead to oxidation and corrosion damage. At this time, the dual-head motor 51 drives the two first rotating shafts 21 to rotate in opposite directions through the meshing of the first bevel gear 25 and the second bevel gear 54, and the two protective covers 23 close. During this process, the support plate 12 can be inserted between the two sealing blocks 241 to form a primary seal, and make the contact cross section between the protective cover 23 and the support plate 12 C-shaped, extending the air diffusion path and preventing humid air from entering directly. The rotation of the first rotating shaft 21 can drive the threaded rod 31 to rotate, which in turn drives the threaded block 34 to translate. When the threaded block 34 moves towards the connecting plate 43, the connecting plate 43 compresses the piston cylinder 42 through the abutment rod 35. The piston cylinder 42 further transmits the increased pressure to the sealing airbag 242 through the second connecting pipe 44 and the first connecting pipe 244, causing it to expand, thereby achieving a secondary seal at the contact seam between the protective cover 23 and the support body 1. After the two protective covers 23 are closed, the contact seam at the bottom is Z-shaped. The contact surfaces of the two protective covers 23 are all elastic sealing gaskets. When the two protective covers 23 are closed, the contact surfaces of the two protective covers 23 are tightly pressed together by the rotational pressing action, thereby achieving the sealing of the contact seam of the two protective covers 23.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
