Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crane equipment, in particular to a multi-functional intelligent gantry crane. Background Art
[0002] A gantry crane is a deformed equipment of a bridge crane, also known as a gantry crane or gantry hoist. Its main structure includes a gantry frame, which is supported on the ground track through two side legs and runs on it. Gantry cranes are widely used in outdoor freight yards, storage yards and bulk cargo handling operations. Due to their high site utilization rate, wide operation range and strong adaptability, they are widely used in port freight yards.
[0003] However, in actual applications, when the hook hoists the winding roller through the hanger, the hook and the hanger are all suspended by the steel cable of the gantry crane. Therefore, the entire hanger is prone to rotational shaking due to inertia. If it hits someone during the shaking process, it may cause serious production accidents. Therefore, generally, two workers need to stand at both ends of the hanger to support the hanger during use to prevent accidents caused by the rotational shaking of the hook and the hanger. Summary of the Utility Model

Specific embodiments
[0029] In order to make the technical problems, technical solutions, and beneficial effects to be solved by the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0030] Based on this, in order to improve the technical problem that in the related art, during the process of a crane lifting an object, the hanging frame is prone to rotational shaking due to inertia, posing a certain safety hazard, the embodiments of the present application provide the following solutions.
[0031] Please refer to Figures 1 to 5 together. The embodiments of the present application provide a multifunctional intelligent gantry crane, including a support assembly 10, a sliding mechanism 20, a lifting mechanism 30, and a multi-stage telescopic rod 40;
[0032] The support assembly 10 includes a bracket 11 and a cross beam 12, and the bracket 11 is disposed at both ends of the cross beam 12;
[0033] The sliding mechanism 20 includes a hoisting frame 21 and a driving wheel 22. The driving wheel 22 is rotatably disposed on the hoisting frame 21. The driving wheel 22 is slidably connected to the cross beam 12. The hoisting frame 21 is connected with a hook 13 through a hoisting mechanism 30;
[0034] One end of the multi-stage telescopic rod 40 is disposed on the hoisting frame 21, and the other end is connected to the hook 13.
[0035] In the technical solution described above in the embodiment of the present application, at least the following technical effects are achieved:
[0036] When the crane hoists an object, the multi-stage telescopic rod 40 contracts for cooperation. When the hanging bracket is likely to rotate and shake due to inertia, the multi-stage telescopic rod 40 uses the relative sliding or telescopic movement between multiple rods to change the length of the entire rod. The multiple rods in the multi-stage telescopic rod 40 abut against each other to offset the shaking potential energy of the hanging bracket, reducing potential safety hazards.
[0037] Optionally, in some embodiments, please refer to Figures 1 to 5 , the multi-stage telescopic rod 40 includes cylinders 41 of at least two sizes, and the cylinders 41 of different sizes are nested from outside to inside in order from large to small.
[0038] With such a setting, a large sliding seat 42 and a small cylinder 41 with a smaller size are embedded inside a large cylinder 41 with a larger size. The small cylinder 41 is fixedly connected to the large sliding seat 42; a smaller small sliding seat 42 is embedded inside the small cylinder 41, and the smaller small sliding seat 42 is connected to a smaller cylinder 41. While the large sliding seat 42 moves, the small cylinder 41 can move together, so that the small cylinder 41 can extend or retract inside the large cylinder 41 to achieve the telescopic function.
[0039] Optionally, in some embodiments, please refer to Figures 4 to 5 , the multi-stage telescopic rod 40 further includes sliding seats 42 of at least two sizes. Along the direction of the inner wall of each cylinder 41, a plurality of spaced-apart ones are fixed. A plurality of rollers 44 are installed on the sliding seat 42, and the rollers 44 can roll along the slideway 43.
[0040] With such a setting, the rollers 44 on the large sliding seat 42 can roll along the slideway 43 to achieve rolling friction; along the circumferential direction of the inner wall of each cylinder 41, four spaced-apart slideways 43 are fixed, so that the sliding seat 42 can be slidably installed around the inner wall of the larger cylinder 41 through the rollers 44 and the slideways 43, so that when the small cylinder 41 extends or retracts inside the large cylinder 41, it is difficult to rotate or shake.
[0041] Optionally, in some embodiments, refer to Figures 1 to 2 , two sets of multi-stage telescopic rods 40 are provided on the lifting frame 21, and the two sets of multi-stage telescopic rods 40 are respectively on both sides of the hook 13.
[0042] With this arrangement, the multi-stage telescopic rods 40 can limit both sides of the hook 13, further reducing the probability of the hook 13 shaking and rotating during movement.
[0043] Optionally, in some embodiments, refer to Figures 1 to 2 , the sliding mechanism 20 further includes a driven wheel 23 and a first driving member 24. The driven wheel 23 is slidably connected to the cross beam 12. The first driving member 24 and the driven wheel 23 are provided on the lifting frame 21. The driven wheel 23 is arranged on the side of the cross beam 12 away from the driving wheel 22, and the output end of the first driving member 24 is in transmission connection with the driving wheel 22.
[0044] With this arrangement, before the gantry crane lifts a heavy object, the position of the lifting frame 21 and the hook 13 is adjusted by driving the sliding wheel through the first driving member 24. Among them, the sliding wheels and the driven wheel 23 on both sides of the cross beam 12 can keep the lifting frame 21 stable during sliding, and the first driving member 24 drives the sliding wheel to rotate, which can keep the transmission process from slipping easily, make the transmission more stable, and also keep an accurate transmission ratio.
[0045] Optionally, in some embodiments, refer to Figures 1 to 3 , the lifting mechanism 30 includes a steel cable 31, a movable pulley 32, a wire winding disc 33 and a second driving member 34. One end of the steel cable 31 is connected to the wire winding disc 33, and the other end passes around the movable pulley 32 and is fixedly connected to the lifting frame 21. The movable pulley 32 is rotatably arranged on the hook 13, and the driving end of the second driving member 34 is connected to the wire winding disc 33.
[0046] With this arrangement, after the position of the sliding mechanism 20 on the cross beam 12 is adjusted, the heavy object can be hung on the hook 13, and then the wire winding disc 33 winds up the steel cable 31 by driving the second driving member 34, so that the hook 13 lifts the heavy object upwards, and the operation is simple and convenient.
[0047] Optionally, in some embodiments, refer to Figures 1 to 3 , a tongue piece 131 is hinged at the opening of the hook 13.
[0048] With this arrangement, in order to prevent the heavy object from falling off, a safety tongue piece 131 is designed on the hook 13, which can play a certain blocking role when the heavy object shakes. The tongue piece 131 utilizes the self-locking principle of spring contraction, thus ensuring that no unhooking accident occurs during the lifting process.
[0049] Optionally, in some embodiments, refer to Figure 1 , a plurality of universal wheels 14 are provided at the bottom of the bracket 11.
[0050] With such a setting, the staff can move the support assembly 10 through the universal wheels 14, thereby facilitating the staff to move heavy objects.
[0051] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
