Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a rail reinforcement device for a gantry crane. Background Art

[0002] A gantry crane is a bridge-type crane whose bridge is supported on the ground track by legs on both sides. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. They are mainly used for outdoor freight yards, material yards, and loading and unloading operations of bulk cargo. In order to ensure the safety and stability of the gantry crane, its operating track must undergo strict reinforcement operations, otherwise the gantry crane will find it difficult to withstand frequent high-level gusts and strong typhoons.

[0003] Existing gantry crane track reinforcement devices mostly use several steel plates welded to the track, and then fixed to the ground with bolts. The fixing direction is relatively single. After long-term use, the bolts are easily corroded, causing the track to loosen and reducing the track's firmness. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0043] Refer to the attached Figure 1 As shown, the gantry crane track reinforcement device includes:

[0044] The concrete base 1 has an upper surface provided with a mounting groove 11 for accommodating the bottom of the gantry crane track and a slot 12 symmetrically arranged about the mounting groove 11;

[0045] There are several pressing plates 2, one of which is pressed and welded to the gantry crane rail, and the other is inserted into the slot 12 to limit the position of the pressing plate 2 in the front, back, left and right directions;

[0046] Top bolts 3, used to fix the pressing plate 2 to the concrete base 1 from the top;

[0047] The side bolts 4 are used to fix the pressing plate 2 to the concrete base 1 from the side.

[0048] In this embodiment, after the bottom of the gantry crane rail is placed in the installation groove 11, the front, rear, left and right directions of the gantry crane rail are limited. In addition, in this embodiment, the depth requirement of the installation groove 11 is 1-3 cm so that the subsequent use of the gantry crane rail will not be affected while limiting the gantry crane rail. Subsequently, several pressure plates 2 are welded to the gantry crane rail on one side, and the other side is inserted into the slot 12, so that the bottom position of the gantry crane rail is further limited. Finally, the pressure plate 2 is firmly fixed to the concrete base 1 using the top bolts 3 and the side bolts 4 respectively.

[0049] In the above solution, the structure of the pressing plate 2 is specifically as follows:

[0050] Refer to the attached Figure 2 and attached Figure 3 As shown, the pressing plate 2 includes:

[0051] Plate 1 21, used for pressing on the gantry crane rail and welding with the gantry crane rail;

[0052] Plate 2 22 is vertically connected to plate 1 21 and contacts the bottom side of the gantry crane track;

[0053] Plate 3 23, horizontally connected to plate 2 22 and placed on the upper surface of the concrete base 1;

[0054] Plate 4 24 is vertically connected to plate 3 23 and inserted into slot 12;

[0055] In order to improve the structural strength of the pressing plate 2 , the pressing plate 2 is integrally formed or welded together by a first plate 21 , a second plate 22 , a third plate 23 and a fourth plate 24 .

[0061] The elastic component 5 includes:

[0062] The spring 51 is horizontally arranged in the side threaded hole 14, and one end is connected to the inner surface of the side threaded hole 14;

[0063] The contact plate 52 is used to contact the side bolt 4 and is fixedly disposed on the other end of the spring 51 so that after the spring 51 is compressed, the contact plate 52 continuously exerts a reaction force on the side bolt 4, thereby achieving an anti-loosening effect;

[0064] Among them, the contact plate 52 is made of rubber material to further improve the use effect;

[0065] In addition, traditional bolts include conventional relaxation and shock-absorbing designs such as gaskets during the installation process, which can also be used in the installation process of the top bolts 3 and the side bolts 4 in this application. This application will not elaborate on this.

[0066] Regarding the above solution, considering the fixing effect of the side bolts 4, from the perspective of preventing loosening, for this purpose, refer to the attached Figure 7 and attached Figure 8 As shown, in another embodiment, the side threaded hole 14 is a through hole, and the two side bolts 4 on opposite sides are connected by a docking assembly 6; specifically, the structure of the docking assembly 6 is as follows:

[0067] The docking assembly 6 includes:

[0068] An internally threaded tube 61 is fixedly connected to one of the side bolts 4;

[0069] The external threaded rod 62 is fixedly connected to the other side bolt 4, and when the two side bolts 4 are connected to the side threaded holes 14, the external threaded rod 62 is threadedly connected to the internal threaded tube 61, thereby achieving the purpose of fixed connection of the two relative side bolts 4.
