[0022] In order to make the technical means, technical features, utility model objectives and technical effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific illustrations.

[0023] like Figure 1 As shown, a gantry crane anchoring device includes a crane body 1, a track 2 and an anchoring assembly. The crane body 1 is movably connected to the track 2, and the anchoring assembly is installed on the crane body 1 to achieve anchoring of the crane body 1 in a non-working state, thereby ensuring the stability of the crane body 1 and protecting the safety of equipment and personnel.

[0024] like Figure 2 As shown, a mounting plate 3 is fixedly connected to one side of the crane body 1, an anchoring assembly is connected to the mounting plate 3, a first anchoring block 5 is connected to the side wall of one side of the track 2, and a second anchoring block 6 is installed on the ground and on one side of the track 2. The mounting planes of the first anchoring block 5 and the second anchoring block 6 are perpendicular to each other. Accordingly, the anchoring assembly is connected to the mounting plate 3 through a pivot, so that the anchoring assembly can rotate relative to the mounting plate 3. According to actual working conditions, the anchoring assembly can be rotated to cooperate with the first anchoring block 5 and / or the second anchoring block 6 to achieve anchoring of the crane body 1. The number of the mounting plate 3, the anchoring assembly, the first anchoring block 5 and the second anchoring block 6 can be multiple to ensure reliable anchoring of the crane body 1. The positions of the first anchoring block 5 and the second anchoring block 6 can correspond one to one or be staggered to ensure the flexibility of the anchoring position of the crane body 1. In order to ensure the stable and reliable anchoring connection between the anchoring assembly and the first anchoring block 5 and the second anchoring block 6, a first slot 7 is processed on the first anchoring block 5 and a second slot 8 is processed on the second anchoring block 6. When anchoring, the anchoring assembly can be inserted into the first slot 7 and / or the second slot 8 accordingly.

[0025] like Figure 2-Figure 4As shown, the anchor assembly includes a mounting base plate 9, a mounting block 10 and an anchor rod 11. One end of the mounting base plate 9 is pivotally hinged to the mounting plate 3. The mounting base plate 9 can rotate relative to the mounting plate 3 around the hinge point. The mounting block 10 is integrally connected to the surface of the mounting base plate 9. A guide groove 12 is processed on the mounting block 10. The guide groove 12 runs through the length direction of the mounting block 10. The anchor rod 11 is inserted and connected in the guide groove 12 and can slide relatively in the guide groove 12. Through the sliding of the anchor rod 11 in the guide groove 12, the bottom end of the anchor rod 11 is inserted into the first slot 7 and / or the second slot 8 to realize the anchoring of the crane body 1, or the bottom end of the anchor rod 11 is pulled out from the first slot 7 and / or the second slot 8 to release the anchoring of the crane body 1.

[0026] In order to enhance the stability of the anchor rod 11 after anchoring, ratchets 13 are processed on the two side walls on the left and right of the anchor rod 11, and ratchets 14 are installed on the mounting block 10 and on both sides of the anchor rod 11. The middle part of the ratchet 14 is hinged to the mounting block 10, and the front end of the ratchet 14 cooperates with the ratchet 13. Two clamp handles 15 are also installed on the mounting block 10. The two clamp handles 15 are staggered with each other, and the middle parts of the two clamp handles 15 are hinged to each other on the mounting block 10. The front ends of the two clamp handles 15 are respectively connected to the rear ends of the two ratchet 14. Specifically, the front ends of the clamp handles 15 are processed with slots, and the rear ends of the ratchet 14 are processed with pins. The pin is connected to the slot of the clamp handle 15, and can rotate relative to the slot and slide in the slot. A spring 16 is connected between the rear ends of the two clamp handles 15, one end of the spring 16 abuts on one of the clamp handles 15, and the other end of the spring 16 abuts on the other clamp handle 15. Through the action of the spring 16, the rear ends of the two clamp handles 15 are separated from each other and opened, and the front ends of the clamp handles 15 are driven to open through the lever principle, and through the connection with the pawl 14, the pawl 14 is driven to rotate around the hinge point between it and the mounting block 10, so that the front end of the pawl 14 is clamped with the ratchet 13, fixing the position of the anchor rod 11 and improving the stability of the anchoring;

[0027] A tension spring 17 is connected between the mounting block 10 and the anchor rod 11, a connecting column 18 is threadedly connected to the mounting block 10, and another connecting column 18 is threadedly connected to the anchor rod 11. The tension spring 17 is connected between the two connecting columns 18. When the anchor rod 11 is pushed to achieve anchoring, the tension spring 17 is stretched and stores force. When the anchoring of the crane body 1 needs to be released, the tension of the tension spring 17 can assist the anchor rod 11 to quickly slide out and rebound from the first slot 7 and / or the second slot 8. A handle 19 is installed at the top of the anchor rod 11, and the handle 19 can be used to perform corresponding operations on the anchor rod 11, thereby improving the convenience of operation and achieving the purpose of saving effort.

[0028] like Figure 2 and Figure 4As shown, when the mounting base plate 9 is rotated into position relative to the mounting plate 3, the relative position between the mounting plate 3 and the mounting base plate 9 is fixed by the connecting plate 4, and the connecting plate 4 is installed on one side or both sides of the mounting plate 3. Specifically, a pin hole 41 is processed at one end of the connecting plate 4, and the connecting plate 4 is hingedly connected to the mounting plate 3 through the pin hole 41, so that the connecting plate 4 can rotate relative to the mounting plate 3, and two fixing holes 42 are processed at the other end of the connecting plate 4 and at a position near the middle of the connecting plate 4, and a threaded hole 91 is processed on the side wall of the mounting base plate 9. Bolts pass through the fixing holes 42 and are threadedly connected in the threaded holes 91 to fix the connecting plate 4, thereby realizing the connection between the mounting base plate 9 and the mounting plate 3. When the mounting base plate 9 is perpendicular to the mounting plate 3, the threaded hole 91 corresponds to one of the fixing holes 42, and when the mounting base plate 9 is parallel to the mounting plate 3, the threaded hole 91 corresponds to the other fixing hole 42.

[0029] The working principle of the utility model is:

[0030] During use, when the crane body 1 needs to be anchored, the crane body 1 is moved along the track 2 to the position of the anchor assembly corresponding to the first anchor block 5 and / or the second anchor block 6, and the anchor rod 11 is pushed to slide in the guide groove 12 of the mounting block 10 by the handle 19, and the lower end of the anchor rod 11 is inserted into the first slot 7 / the second slot 8. After being inserted into place, the pawl 14 is clamped in the ratchet 13 to lock the anchor rod 11, thereby realizing the anchoring of the crane body 1;

[0031] When anchoring, the mounting base plate 9 can be rotated around the hinge point between the mounting plate 3 and the mounting plate 3 according to specific usage requirements: the mounting base plate 9 is rotated to be parallel to the mounting plate 3, and the anchor rod 11 corresponds to the first anchor block 5; the mounting base plate 9 is rotated to be perpendicular to the mounting plate 3, and the anchor rod 11 corresponds to the second anchor rod 11. When there are multiple anchoring assemblies, multiple anchor rods 11 can be anchored on the first anchor block 5, or multiple anchor rods 11 can be anchored on the second anchor block 6, or multiple anchor rods 11 can be anchored on the first anchor block 5 and the second anchor block 6 respectively, so as to improve the stability and flexibility of anchoring;

[0032] When it is necessary to release the anchor, the rear ends of the two clamp handles 15 are manually pinched to overcome the elastic force of the spring 16. Through the lever principle of the clamp handles 15 and the sliding hinge with the pawl 14, the front end of the pawl 14 is driven to disengage from the ratchet 13, releasing the clamping of the pawl 14 on the ratchet 13. Under the rebound force of the tension spring 17 and human pulling, the anchor rod 11 slides in the opposite direction of the guide groove 12 to reset and disengage from the first slot 7 and / or the second slot 8.

[0033] The above description is only a preferred embodiment of the utility model, and is not intended to limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made according to the content of the patent application scope of the utility model should belong to the technical scope of the utility model.
