Description

Technical Field

[0001] The present invention relates to the technical field of hanger structures, and in particular to a gantry hanger structure capable of rapidly adjusting a two-dimensional posture. Background Art

[0002] The existing hanger structure has a relatively single installation surface and a contact surface with the target equipment, poor interface versatility, and can only be adjusted in one dimension. Moreover, after the target equipment is installed, the adjustment operation is difficult, the adjustment range is limited, and the accuracy is poor. These problems are obvious. Especially for large-scale, unconventional equipment, hangers on the market are relatively scarce and it is difficult to meet the actual working posture requirements of the equipment. Summary of the Invention

[0003] In response to the above problems, the present invention provides a gantry hanger structure that can quickly adjust the two-dimensional posture. It cooperates with the two-way adjustment structure to realize the multi-posture real-time adjustment and installation requirements of large-scale lifting equipment.

[0004] A gantry hanger structure capable of rapidly adjusting a two-dimensional posture, the technical solution of which is as follows: the gantry hanger structure is assembled on a target device, the target device being a large-volume target device, and is characterized in that it comprises:

[0005] a gantry;

[0006] an adjusting screw;

[0007] A rotary adjustment fixing seat, which includes a bottom fixing part, an upper driving rotation part, and a positioning connection part;

[0008] The rotary boom comprises a lower convex positioning rod, a middle rotation drive seat, and an upper convex connecting rod, wherein a connecting joint is fixedly provided on the top of the upper convex connecting rod;

[0009] The two side columns of the gantry are connected to the corresponding side walls of the target device through a rotating shaft 1, and the crossbeam of the gantry is arranged in the upper area of ​​the upper surface of the target device;

[0010] The crossbeam and the upper surface of the target device are connected by an adjusting screw, and the two ends of the adjusting screw in the length direction are pivotally connected to the lower surface of the crossbeam and the upper surface of the target device respectively;

[0011] A rotary adjustment fixing seat is fixed on the upper surface of the crossbeam, and the lower convex positioning rod is connected to the positioning connection part through the second rotating shaft and is limited in the height direction; the upper driving rotating part is arranged toward the driving end of the middle rotating driving seat, and the upper driving rotating part drives the middle rotating seat to deflect relative to the rotary adjustment fixing seat with the lower convex positioning rod as the center.

[0012] It is further characterized by:

[0013] The driving end of the middle rotary drive seat is specifically a side convex drive plate, and the upper driving rotary part is a handle screw arranged on both sides of the side convex drive plate. The rod ends of the handle screws on both sides are respectively pressed against the corresponding surfaces of the side convex drive plate. The handle screws operate in the same direction relative to the side convex drive plate, and are used to drive the entire slewing boom to deflect relative to the slewing adjustment fixing seat with the lower convex positioning rod as the center;

[0014] The handle screw includes a screw end and a driving handle, and the head of the screw end that is pressed onto the scoliotic driving plate is a spherical or quasi-spherical structure, ensuring that the pressing is firm and reliable without damaging the scoliotic driving plate;

[0015] The positioning connection part is provided with a positioning hole, and the lower convex positioning rod is inserted into the positioning hole through the second rotating shaft, and the lower convex positioning rod is fixedly sleeved with a limiting sleeve at the upper and lower positions relative to the base plate where the positioning hole is located, thereby ensuring a stable connection between the slewing boom and the slewing adjustment fixing seat;

[0016] The adjusting screw is specifically a bidirectional adjusting screw, which includes a first connecting screw, an adjusting sleeve, and a second connecting screw. The threaded section of the first connecting screw is threadedly connected to one end of the adjusting sleeve in the length direction, and the threaded section of the second connecting screw is threadedly connected to the other end of the adjusting sleeve in the length direction. The end of the first connecting screw away from the adjusting sleeve is pivotally connected to the lower surface of the beam, and the end of the second connecting screw away from the adjusting sleeve is pivotally connected to the upper surface of the target device; when the adjusting sleeve rotates, the first adjusting screw and the second adjusting screw move toward or away from each other at the same time.

[0017] After adopting the above technical solution, the two-dimensional adjustment function of this lifting gantry is realized by tightening or loosening the adjustment screw to achieve the pitch angle adjustment of the target equipment. In addition, the upper driving rotating part drives the driving end of the middle rotating driving seat to move, so that the upper driving rotating part drives the middle rotating seat to deflect relative to the slewing adjustment fixed seat with the lower convex positioning rod as the center. Since the overall position of the lifting rod is fixed, the slewing adjustment fixed seat is deflected, and the target equipment is deflected. It cooperates with the two-way adjustment structure to realize the multi-posture real-time adjustment and installation requirements of large-scale lifting equipment.

DETAILED DESCRIPTION

[0024] A gantry crane structure capable of rapidly adjusting its two-dimensional posture, see Figures 1-4 , which is assembled on the target device 10, which is a large-scale target device, and includes a gantry 20, an adjusting screw 30, a rotary adjustment fixing seat 40, and a rotary boom 50;

[0025] The rotary adjustment fixing seat 40 includes a bottom fixing portion 41, an upper driving rotation portion 42, and a positioning connection portion 43;

[0026] The slewing boom 50 includes a lower convex positioning rod 51, a middle rotation drive seat 52, and an upper convex connecting rod 53. A connecting joint 54 is fixed to the top of the upper convex connecting rod 53, and the connecting joint 54 is fixed to the base portion.

[0027] The gantry 20 includes two side columns 21 and an upper crossbeam 22;

[0028] The two side columns 21 of the gantry 20 are connected to the corresponding side walls of the target device 10 through the rotating shaft 23, and the crossbeam 22 of the gantry 20 is located in the upper area of ​​the upper surface of the target device 10;

[0029] The crossbeam 22 and the upper surface of the target device 10 are connected by an adjusting screw 30, and the two ends of the adjusting screw 30 in the length direction are pivotally connected to the lower surface of the crossbeam and the upper surface of the target device through connecting seats respectively;

[0030] A swivel adjustment fixing seat 40 is fixed to the upper surface of the crossbeam 22, and a bottom fixing portion 41 of the swivel adjustment fixing seat 40 is fixed to the upper surface of the crossbeam 22. In specific implementation, the bottom fixing portion 41 is a plate-like structure and can be fixed by bolting or welding; the lower convex positioning rod 51 is connected to the positioning connection portion 43 through the second rotating shaft, and is also connected in a height-limited direction; the upper driving rotating portion 42 is arranged toward the driving end of the middle rotating driving seat 52, and the upper driving rotating portion 42 drives the middle rotating driving seat 52 to deflect relative to the swivel adjustment fixing seat 40 with the lower convex positioning rod 51 as the center.

[0031] When implementing:

[0032] The driving end of the middle rotary drive seat 52 is specifically a side convex drive plate 521. The upper driving rotary portion 42 is a handle screw 44 arranged on both sides of the side convex drive plate. The rod ends of the handle screws 44 on both sides are respectively pressed against the corresponding surfaces of the side convex drive plate 521. The handle screws 44 operate in the same direction relative to the side convex drive plate 521, thereby driving the entire rotary boom 50 to deflect relative to the rotary adjustment fixing seat 40 with the lower convex positioning rod 51 as the center.

[0033] The handle screw 44 includes a screw end 45 and a driving handle 46. The head of the screw end 45 that is pressed against the side convex driving plate 521 is a spherical or quasi-spherical structure, ensuring a stable and reliable press-attachment without damaging the side convex driving plate 521.

[0034] The positioning connection portion 43 is provided with a through positioning hole 47, in which a bearing 48 is provided. A lower convex positioning rod 51 is arranged through the bearing 48. The lower convex positioning rod 51 is the second rotating shaft, and the lower convex positioning rod 51 is fixedly sleeved with a limiting sleeve 49 at the upper and lower positions relative to the base plate where the through positioning hole is located, thereby ensuring a stable connection between the slewing boom 50 and the slewing adjustment fixing seat 40.

[0035] The adjusting screw 30 is specifically a bidirectional adjusting screw, which includes a first connecting screw 31, an adjusting sleeve 32, and a second connecting screw 33. The threaded section of the first connecting screw 31 is threadedly connected to one end of the adjusting sleeve 32 in the length direction, and the threaded section of the second connecting screw 33 is threadedly connected to the other end of the adjusting sleeve 32 in the length direction. The end of the first connecting screw 31 away from the adjusting sleeve 32 is pivoted to the lower surface of the crossbeam 22, and the end of the second connecting screw 33 away from the adjusting sleeve 32 is pivoted to the upper surface of the target device 10; when the adjusting sleeve 32 rotates, the first adjusting screw 31 and the second adjusting screw 33 move toward or away from each other at the same time.

[0036] Its working principle is as follows: the two-dimensional adjustment function of this lifting gantry is achieved by tightening or loosening the two-way adjustment screw to adjust the pitch angle of the target equipment. In addition, the upper drive rotating part drives the driving end of the middle rotation driving seat to move, so that the upper drive rotating part drives the middle rotation seat to deflect relative to the slewing adjustment fixed seat with the lower convex positioning rod as the center. Since the overall position of the boom is fixed, the slewing adjustment fixed seat is deflected, thereby causing the target equipment to perform a deflection operation; it cooperates with the two-way adjustment structure to realize the multi-posture real-time adjustment and installation requirements of large-scale lifting equipment.
