Description

Technical Field

[0001] The utility model relates to the technical field of automobile cranes, in particular to a vehicle crane outrigger fixing device. Background Art

[0002] At present, most mobile cranes must fully extend their outriggers before starting the lifting operation. Then, depending on the ground conditions, the outriggers may need to be adjusted to keep the crane level, and the length of the outriggers may need to be adjusted to provide adequate support according to the needs of the lifting operation. However, in special environments with poor geological conditions (soft, muddy or uneven ground), near railways, important buildings (structures), and under conditions of high safety requirements, the outriggers of traditional mobile cranes are prone to dents when operating on soft and muddy ground, which threatens the stability of the mobile crane during operation and may even cause it to overturn in severe cases.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0020] Example 1

[0021] like Figure 1-3 A vehicle crane leg fixing device is shown, which includes a support frame 100 arranged at the bottom of the vehicle; the support frame 100 includes four support legs 120 respectively arranged at the tires of the vehicle, and a cross beam 110 connecting the support legs 120 and the vehicle is provided between the support legs 120 and the vehicle; it is characterized in that a steel sheet pile 210 vertically inserted into the ground is provided at the support leg 120, and a connecting rope 220 for connecting the steel sheet pile 210 and the cross beam 110 is provided at the upper end of the steel sheet pile 210.

[0022] Through the car crane leg fixing device in this embodiment, when the staff improves the stability of the car crane operation, in order to ensure the stability of the car crane hoisting process, they only need to ensure that the support frame 100 is firmly on the bottom of the car, select 9m long IV type Larsen steel sheet piles 210 and insert them into the ground, and reserve a part of the steel sheet piles 210 to be exposed on the ground, and firmly connect the steel sheet piles 210 to the crossbeam 110 of the support frame 100 through the connecting rope 220. During the hoisting process of the car crane, when the boom needs to turn to another direction for hoisting operations, the legs will be tilted due to the uneven force on the legs caused by the rotation of the boom, and the instability caused by the uneven force on the legs caused by the depression of the ground. In the utility model, the car crane support foot 120 is subjected to a downward force through the steel sheet piles 210 inserted into the ground, which can effectively resist the influence of external forces, prevent the car crane from tilting or moving during the operation, ensure the safety of the hoisting operation, and effectively reduce the instability or overturning caused by poor ground conditions.

[0023] In this embodiment, the steel sheet pile 210 is made of stainless steel.

[0024] The steel sheet pile 210 in this embodiment is made of stainless steel, which can be specifically a Type IV Larsen steel plate. Compared with traditional steel plates, the Type IV Larsen steel plate has good force-bearing performance and high strength, and can better resist soil and water pressure, providing a stable support for the vehicle crane leg fixing device. At the same time, the Type IV Larsen steel plate is a common engineering material with good durability and reusability. Therefore, the steel sheet pile 210 selected in this embodiment as the vehicle crane leg fixing device can not only meet the current operation needs, but also can be reused in other future projects, reducing costs.

[0025] In this embodiment, a through hole 211 is provided at the upper end of the steel sheet pile 210 for the connecting rope 220 to pass through.

[0026] By providing a through hole 211 for the connecting rope 220 to pass through at the upper end of the steel sheet pile 210 in this embodiment, specifically, 0.5m of the steel sheet pile 210 is reserved to be exposed above the ground when being driven in. At the same time, a through hole 211 with a diameter of 0.1m is reserved 0.1m below the top of the steel sheet pile 210, which can improve construction flexibility, optimize construction efficiency, reduce maintenance costs, adapt to complex environments, and enhance safety.

[0027] In this embodiment, a reinforcing steel plate 212 is provided at the upper end of the steel sheet pile 210 near the through hole 211 .

[0028] By providing a reinforcing steel plate 212 at the upper end of the steel sheet pile 210 near the through hole 211 in this embodiment, the strength and stability of the connection point can be enhanced, ensuring that the connection between the steel sheet pile 210 and the crossbeam 110 of the support frame 100 formed by the connecting rope 220 is more firm and reliable.

[0029] In this embodiment, a D-shaped shackle 230 is provided on the connecting rope 220 for connecting the through hole 211 and the connecting rope 220.

[0030] By providing the D-type shackle 230 for connecting the through hole 211 and the connecting rope 220 on the connecting rope 220 in this embodiment, the tension of the connecting rope 220 can be effectively transmitted to the steel sheet pile 210, further enhancing the overall stability and safety of the automobile crane leg fixing device. In addition, this connection method is not only simple to install and disassemble, but also firm and reliable.

[0031] In this embodiment, a rubber pad 240 is provided between the connecting rope 220 and the crossbeam 110 .

[0032] The rubber pad 240 provided between the connecting rope 220 and the crossbeam 110 in this embodiment can be L-shaped, which can significantly reduce the direct contact area between the connecting rope 220 and the crossbeam 110, thereby effectively avoiding wear and noise problems caused by hard contact. The elastic buffering effect of the rubber pad 240 can also disperse the tension transmitted by the connecting rope 220 to a certain extent, protecting the surface of the crossbeam 110 from damage. Secondly, the L-shaped shape design enables the rubber pad 240 to fit closely to the contour of the crossbeam, providing more stable and reliable support. At the same time, it prevents displacement or falling off during the ground hoisting process, ensuring the durability and safety of the connection between the connecting rope 220 and the crossbeam 110.

[0033] In this embodiment, the connecting rope 220 is a steel wire rope.

[0034] In this embodiment, the connecting rope 220 is a steel wire rope, and specifically a high-strength steel wire rope with a diameter of 16 mm can be selected. By using a high-strength, wear-resistant, corrosion-resistant and easy-to-maintain steel wire rope as the connecting rope, the connection reliability and safety between the steel sheet pile 210 and the beam 110 can be enhanced.

[0035] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0036] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
