The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figures 1 to 3The preferred embodiment of the utility model is a grab reinforcement device, comprising: a support plate 10, placed on a support surface, for supporting a grab leg 41; a ground anchor 20, fixed on the support surface, a cable 21 is provided on the ground anchor 20, and the cable 21 can be sleeved on the grab leg 41 to press the grab leg 41 downward onto the support plate 10; a door frame 30, which is in an inverted "U" shape and is fixed on the support surface, and its inner opening can be used for the grab leg crossbeam 32 to pass through and its inner height is adapted to the top surface height of the grab leg 42. The grab bucket reinforcement device utilizes the support plate 10 to provide stable support for the grab bucket support leg 41, and can increase the force application area of ​​the grab bucket support leg 41 on the support surface, effectively preventing the support surface from being concave. The ground anchor 20 can press the grab bucket support leg 41 against the support plate 10, and at the same time, the door frame 30 can limit the grab bucket support leg 42 to prevent the grab bucket support leg 42 from tilting up, thereby effectively improving the stability of the grab bucket support, reducing the safety risk of instability and overturning during the grab bucket operation, and ensuring construction safety. At the same time, the structure is simple and reliable, and is easy to process, manufacture and use.

[0027] The supporting surface in the present invention refers to the ground, rock surface, cement surface, etc. in the actual construction environment.

[0028] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0029] In this embodiment, the inner width of the gantry 30 is adapted to the width of the grab bucket leg 42, thereby further limiting the lateral movement of the grab bucket leg 42 and further reducing the safety risk. In combination with the description of the utility model, it can be understood by those skilled in the art that in the utility model, the inner height of the gantry 30 is adapted to the top surface height of the grab bucket leg 42, which means that the height of the inner height of the gantry 30 can limit the upward position of the grab bucket leg 42. In specific applications, according to actual needs, the inner top surface of the gantry 30 can be selected to abut against the top surface of the grab bucket leg 42, or a small gap can be selected between the inner top surface of the gantry 30 and the top surface of the grab bucket bracket; similarly, the inner width of the gantry 30 is adapted to the width of the grab bucket leg 42, and the inner side surface of the gantry 30 can be selected to abut against the outer side surface of the grab bucket leg 42, or a small gap can be selected between the inner side surface of the gantry 30 and the outer side surface of the grab bucket leg 42, both of which can play a role in limiting the lateral deflection of the grab bucket leg 42.

[0030] In this embodiment, the ground anchor 20 and the gantry 30 are respectively arranged on opposite sides of the support plate 10, so that the ground anchor 20 and the cable 21 can limit the movement of the grab bucket foot 41 toward the grab bucket leg 42, further preventing the grab bucket from becoming unstable, and being safer and more reliable. In other embodiments, the ground anchor 20 can also be selected to be arranged on other sides of the support plate 10, and is not limited thereto.

[0031] In this embodiment, the support plate 10 is a steel plate, which has high structural strength, is not prone to deformation, and is easy to obtain at the construction site. In other embodiments, the support plate 10 can also be made of other suitable materials such as wood boards as needed, but is not limited thereto.

[0032] In this embodiment, an anti-skid plate 11 is provided on the support plate 10, and the anti-skid plate 11 is used to pad between the support plate 10 and the grab bucket support foot 41, so that the grab bucket support foot 41 can be further prevented from sliding and causing the grab bucket to become unstable, which is safer and more reliable. The anti-skid plate 11 can be made of common anti-skid materials and structures such as rubber plates and rubber plates, or metal materials such as steel plates with rough surfaces. Those skilled in the art can flexibly choose according to needs. In this embodiment, a handle 12 is provided on the anti-skid plate 11, which can prevent the anti-skid plate 11 from being too tightly adhered to the support plate 10 after being pressed and unable to be separated, and is convenient to use.

[0033] In this embodiment, the anchor 20 and the cable 21 are connected by a spring, so that on the one hand, the cable 21 can be easily set on the grab bucket support leg 41, and on the other hand, it can also provide a certain buffer to prevent the cable 21 from being broken due to excessive force, which is safer and more reliable. In this embodiment, the cable 21 is a steel wire rope with high tensile strength and is easy to obtain and use at the construction site. In other embodiments, the cable 21 can also be made of other suitable materials such as ropes and chains, but is not limited to this.

[0034] In this embodiment, the door frame 30 includes two vertical beams 31 and a horizontal beam 32 fixed on the top of the two vertical beams 31. The vertical beams 31 and the horizontal beams 32 are both I-beams, which have a simple and reliable structure and are easy to obtain materials and process and manufacture. In this embodiment, the horizontal beam 32 and the vertical beam 31 are welded together, and a bottom plate 33 is welded to the bottom of the vertical beam 31. The bottom plate 33 is fixed to the support surface by expansion screws. Similarly, the anchor 20 can also be fixed to the support surface by expansion screws. In other embodiments, the horizontal beam 32 and the vertical beam 31 can also be fixed together by screws, bundling, etc., and the door frame 30 and the anchor 20 can also be fixed to the support surface by other commonly used fixing methods, but are not limited to this.

[0035] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0036] The above description is only a preferred implementation mode of the present utility model. Any technical solution that achieves the purpose of the present utility model by basically the same means belongs to the protection scope of the present utility model.
