Description

Technical Field

[0001] The present application relates to the field of hoisting technology, and in particular to a double-beam gantry crane with an anti-tipping structure. Background Art

[0002] Double-beam gantry crane is a commonly used lifting equipment, which is mainly composed of bridge, trolley running mechanism, car running mechanism, lifting mechanism and electrical control system. The bridge is the main structure of the crane, which can bear the dead weight of the crane and the weight of the hoisting load. It is usually composed of two parallel main beams and the cross beam connecting them, and has sufficient rigidity and stability.

[0003] Double-girder gantry cranes are prone to tipping over due to improper operation, overloading, foundation problems and structural design defects during operation. For example, overloading and incorrect lifting methods can cause the crane to become unstable and easily tip over. In addition, exceeding the rated lifting capacity of the crane will reduce its stability, making it prone to tipping over. Even when the crane is affected by dynamic loads during operation, such as inertia and vibration, it is prone to tipping over.

[0004] Cranes can improve their reliability and safety through anti-overturning and anti-rollover analysis, adding counterweights to improve stability, and redundant design of key components. However, there are many factors that cause overturning, and a more suitable technical solution is needed.

[0005] Therefore, it is necessary to provide a double-beam gantry crane with an anti-tipping structure to solve the problems raised in the above background technology. Summary of the invention

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solution: a double-beam gantry crane with an anti-tilt structure, comprising:

[0007] A base, on which a crossbeam frame assembly is fixedly arranged, and the base and the crossbeam frame assembly are arranged in two groups of symmetrical arrangements, the crossbeam frame assembly includes a column obliquely fixedly arranged on the base, and a hanging beam hinged to the column, and a hinged rod is connected between the column and the hanging beam;

[0008] The parallel beam assembly is arranged between the two cross beam frame assemblies, and the parallel beam assembly includes symmetrically arranged transverse beam rails, and the two transverse beam rails are connected by a connecting plate, and a hoisting assembly is also arranged between the two transverse beam rails.

[0009] Furthermore, as a preference, the crossbeam frame assembly also includes an auxiliary support rod, the two ends of which are respectively fixedly arranged on the column and the base, and a plurality of positioning holes are evenly distributed on the suspension beam, the positioning holes are used to assist in the installation of support spokes, and the support spokes are used to carry the transverse beam rails.

[0010] Further, as a preference, the portion of the hanging beam extending to above the connecting plate is provided with a connecting seat for fixedly connecting the connecting plate and the hanging beam.

[0011] Further, as a preference, the parallel beam assembly also includes a fixing plate fixedly arranged below the transverse beam rail, the fixing plate is used to connect the supporting spoke plate, and the opposite sides of the two transverse beam rails are designated as their respective inner sides, and a track groove is opened on the inner side of the transverse beam rail, and the track groove is connected to the outer side of the transverse beam rail.

[0012] Further, as a preference, the connecting plate includes an upper adapter plate, an adapter spoke plate and a lower adapter plate, wherein the upper adapter plate is fixedly connected to the two transverse beam rails through the adapter spoke plate, the upper adapter plate is provided with a connecting slot hole matching the connecting seat, the lower adapter plate is located below the transverse beam rail, and a plurality of counterweight joints, detection parts and lifting brackets are fixedly provided on the lower adapter plate.

[0013] Further, as a preference, the hoisting assembly comprises:

[0014] An auxiliary motor, whose output end is connected to an auxiliary wheel, the auxiliary motor and the auxiliary wheel are both arranged at the position of the hanging bracket, and a limit shell is installed on the auxiliary wheel;

[0015] An adjusting roller 1 is slidably arranged in the track groove;

[0016] Hoisting wheels, located on both sides of the auxiliary wheel, the hoisting wheels are hung with hooks, and an adjusting roller 2 is rotatably arranged on the transverse beam rail at a position directly above the hoisting wheels;

[0017] A slider is slidably disposed in the track groove, and the slider is fixedly connected to the lower adapter plate;

[0018] The cable is connected in series with the adjusting roller 1, the adjusting roller 2, the auxiliary wheel and the lifting wheel.

[0019] Further, preferably, the cable is hung on the second adjusting roller and the auxiliary wheel, and the lifting wheel is located between the second adjusting roller and the auxiliary wheel, and the lifting wheel is supported by the cable, and there are four evenly distributed groups of lifting wheels and hooks.

[0020] Furthermore, as a preference, the slider is also driven by placing a driving member on the transverse beam rail, so as to enable the slider to slide in the track groove and adjust the lateral displacement of the hook suspension. During the sliding process of the slider, the auxiliary motor rotates to drive the cable belt to operate through the auxiliary wheel, during which the lifting wheel will rotate, but the height position of the lifting wheel and the hook remains unchanged.

[0021] Further, as a preference, the two adjusting rollers located on the same transverse beam rail have two sliding modes, one is that they synchronously approach or move away from each other, and at the same time, the auxiliary wheel is powered by an auxiliary motor to be locked and not rotated, and at the same time, the cable thereon is restricted from sliding, thereby maintaining the synchronous lifting and lowering of the corresponding two lifting wheels; the other is that one of the adjusting rollers does not slide, and the other slides for adjustment, and at the same time, the auxiliary wheel is powered by an auxiliary motor to be locked and not rotated, and at the same time, the cable thereon is restricted from sliding, thereby achieving the lifting of the corresponding single lifting wheel, and the other lifting wheel does not move.

During the movement process, the auxiliary wheel friction drives the cable belt to operate. The lifting wheel follows the transformation in a rolling manner with less friction due to the lifting object and its own weight, thereby realizing a synchronous movement process; the rollers are adjusted to move closer or farther away from each other, and the auxiliary wheel is locked by the auxiliary motor to prevent it from rotating, thereby limiting the sliding of the cable belt thereon and keeping the corresponding two lifting wheels rising and falling synchronously;

[0024] One of the single adjusting rollers does not slide, while the other slides and adjusts. At the same time, the auxiliary wheel is locked and does not rotate due to the power provided by the auxiliary motor, and at the same time, the sliding of the cable thereon is restricted, thereby realizing the lifting and lowering of the corresponding single lifting wheel, while the other lifting wheel does not move. For objects with inconsistent lifting point heights, the height of the hook can be coordinated to keep the objects lifted with a stable center of gravity, effectively reducing the possibility of tipping. In addition, if shaking occurs during lifting and transportation, the auxiliary wheel can be rotated and an adjusting force can be applied to the lifting wheel with the help of the cable to stabilize the center of gravity.

DETAILED DESCRIPTION

[0032] See also Figure 1-Figure 5 In an embodiment of the present application, a double-beam gantry crane with an anti-tilt structure includes:

[0033] A base 1, on which a crossbeam frame assembly 2 is fixedly arranged, and the base 1 and the crossbeam frame assembly 2 are arranged in two groups of symmetrical arrangements. Specifically, a guide wheel is arranged at the lower end of the base 1, and the position of the crossbeam frame assembly 2 can be adjusted in coordination with a track. The crossbeam frame assembly 2 includes a column 21 obliquely fixedly arranged on the base 1, and a suspension beam 22 hinged to the column 21. A hinged rod 23 is connected between the column 21 and the suspension beam 22. Specifically, the hinged rod 23 can be retracted to adjust the inclination angle between the suspension beam 22 and the column 21;

[0034] The parallel beam assembly 3 is arranged between the two cross beam frame assemblies 2, and the parallel beam assembly 3 includes symmetrically arranged transverse beam rails 31, and the two transverse beam rails 31 are connected by a connecting plate 4, and a lifting assembly 5 is also arranged between the two transverse beam rails 31.

[0035] As a preferred embodiment, the crossbeam frame assembly 2 also includes an auxiliary support rod 211, and the two ends of the auxiliary support rod 211 are respectively fixedly arranged on the column 21 and the base 1, and are specifically used to assist in supporting the column 21, and a plurality of positioning holes 221 are evenly distributed on the suspension beam 22, and the positioning holes 221 are used to assist in the installation of support spokes 222, and the support spokes 222 are used to carry the transverse beam rail 31.

[0036] As a preferred embodiment, the suspension beam 22 extends to the portion above the connecting plate 4 , on which a connecting seat 223 is provided for fixedly connecting the connecting plate 4 and the suspension beam 22 .

[0037] It should be explained that by adjusting the deflection angle of the suspension beam 22 and the column 21, the transverse beam rail 31 is overlapped on the supporting spoke plate 222, and the connecting plate 4 and the suspension beam 22 are connected through the connecting seat 223 to stably fix the parallel beam assembly 3.

[0038] As a preferred embodiment, the parallel beam assembly 3 also includes a fixing plate 32 fixedly arranged below the transverse beam rail 31, the fixing plate 32 is used to connect the supporting spoke plate 222, and designates the opposite sides of the two transverse beam rails 31 as their respective inner sides, and a track groove 311 is opened on the inner side of the transverse beam rail 31, and the track groove 311 is connected to the outer side of the transverse beam rail 31.

[0039] In this embodiment, Figure 3 The connecting plate 4 includes an upper adapter plate 41, an adapter spoke plate 42 and a lower adapter plate 43, wherein the upper adapter plate 41 is fixedly connected to the two transverse beam rails 31 through the adapter spoke plate 42, and a connecting slot hole 411 matching the connecting seat 223 is opened on the upper adapter plate 41, and the lower adapter plate 43 is located below the transverse beam rail 31, and a plurality of counterweight joints 44, detectors 45 and hanging brackets 46 are fixedly arranged on the lower adapter plate 43, and the specific counterweight joints 44 are used to hang the counterweight to improve stability, and the detector 45 has built-in sensors for monitoring the hanging state of the hanging object including vibration deviation, etc., so as to provide a reference basis for adjusting other components during transportation.

[0040] In this embodiment, Figure 4-Figure 5 , the hoisting assembly 5 comprises:

[0041] An auxiliary motor 51, whose output end is connected to an auxiliary wheel 52, the auxiliary motor 51 and the auxiliary wheel 52 are both arranged at the position of the hanging bracket 46, and a limit housing 521 is installed on the auxiliary wheel 52;

[0042] An adjusting roller 53 is slidably disposed in the track groove 311. Specifically, the adjusting roller 53 can be driven by a driving member disposed on the outer side of the transverse beam rail 31;

[0043] A hoisting wheel 56 is located on both sides of the auxiliary wheel 52. A hook 58 is hung on the hoisting wheel 56. An adjusting roller 2 55 is rotatably arranged on the transverse beam rail 31 at a position directly above the hoisting wheel 56.

[0044] A slider 57 is slidably disposed in the track groove 311, and the slider 57 is fixedly connected to the lower adapter plate 43;

[0045] The cable 54 is connected in series with the adjusting roller 1 53 , the adjusting roller 2 55 , the auxiliary wheel 52 and the lifting wheel 56 .

[0046] As a preferred embodiment, the cable 54 is hung on the adjusting roller 2 55 and the auxiliary wheel 52, and the lifting wheel 56 is located between the adjusting roller 2 55 and the auxiliary wheel 52, and the lifting wheel 56 is supported by the cable 54. There are four evenly distributed groups of lifting wheels 56 and hooks 58. During the specific lifting process, the load is shared by multiple hooks 58 and lifting wheels 56, and heavy objects are lifted at multiple angles at the same time. The overall load-bearing capacity is more evenly distributed, which is beneficial to improving the lifting stability.

[0047] As a preferred embodiment, the slider 57 is also driven by placing a driving member on the transverse beam rail 31, so as to enable the slider 57 to slide in the track groove 311 and adjust the lateral displacement of the hanging object of the hook 58. In addition, during the sliding of the slider 57, the auxiliary motor 51 rotates through the auxiliary wheel 52 to drive the cable 54 to operate. During this period, the lifting wheel 56 will rotate, but the height position of the lifting wheel 56 and the hook 58 remains unchanged. Specifically, during the entire moving process, the cable 54 is mainly driven by the friction of the auxiliary wheel 52. Because of the lifting object and its own weight, the lifting wheel 56 follows the transformation in a rolling manner with less friction, thereby realizing a synchronous movement process and ensuring the smoothness of the movement.

[0048] As a preferred embodiment, the two adjusting rollers 53 located on the same transverse beam rail 31 have two sliding modes, one is to synchronously approach or move away from each other, and at the same time, the auxiliary wheel 52 is powered by the auxiliary motor 51 to be locked and not rotated, and at the same time, the cable 54 thereon is restricted from sliding, so as to keep the corresponding two lifting wheels 56 rising and falling synchronously; the other is that a single adjusting roller 53 does not slide, and the other slides and adjusts, and at the same time, the auxiliary wheel 52 is powered by the auxiliary motor 51 to be locked and not rotated, and at the same time, the cable 54 thereon is restricted from sliding, so as to realize the lifting of the corresponding single lifting wheel 56, and the other lifting wheel 56 does not move. Specifically, for objects with inconsistent lifting point heights, the height of the hook 58 can be coordinated to keep the objects lifted in a manner with a stable center of gravity, effectively reducing the possibility of tipping.

[0049] It should be explained that during the lifting and transportation process, shaking occurs, and the auxiliary wheel 52 is rotated and an adjustment force is applied to the lifting wheel 56 with the help of the cable 54 to stabilize the center of gravity.

[0050] In the specific implementation, by adjusting the deflection angle of the suspension beam 22 and the column 21, the transverse beam rail 31 is overlapped on the supporting spoke plate 222, and the connecting plate 4 and the suspension beam 22 are connected by the connecting seat 223 to stably fix the parallel beam assembly 3. The counterweight joint 44 is used to hang the counterweight. The detection part 45 has the required built-in sensors to monitor the hanging state of the hanging object, including vibration deviation, etc. During the lifting process, the load is shared by multiple hooks 58 and lifting wheels 56, and the heavy objects are lifted at multiple angles. During the movement, the auxiliary wheel 52 mainly drives the cable belt 54 to operate by friction. The lifting wheel 56 follows the change in a rolling manner with less friction due to the lifting object and its own weight, so as to realize the synchronous movement process; the rollers 53 are adjusted to move closer or farther away from each other, and the auxiliary wheel 52 is locked by the auxiliary motor 51 to prevent it from rotating, so as to limit the sliding of the cable belt 54 thereon and keep the corresponding two lifting wheels 56 rising and falling synchronously;

[0051] A single adjusting roller 53 does not slide, while the other one slides and adjusts. At the same time, the auxiliary wheel 52 is locked by the auxiliary motor 51 and does not rotate. At the same time, the cable 54 thereon is restricted from sliding, thereby realizing the lifting and lowering of the corresponding single lifting wheel 56. The other lifting wheel 56 does not move. For objects with inconsistent lifting point heights, the height of the hook 58 can be coordinated to keep the objects lifted with a stable center of gravity, effectively reducing the possibility of tipping. In addition, during the lifting and transportation process, if there is shaking, the auxiliary wheel 52 is rotated and an adjusting force is applied to the lifting wheel 56 with the help of the cable 54 to stabilize the center of gravity.

[0052] What has been described above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
