Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular relates to a leg-mounting device and a crane installation equipment. Background Technology

[0002] Outriggers are a crucial component of cranes, and their installation is an essential step in the crane's manufacturing and assembly process. However, due to their significant weight, crane outriggers cannot be directly moved manually. In actual assembly, a crane is used to hoist the outriggers to the vicinity of the installation position. Installers stand on either side of the outriggers and forcefully push them into the outrigger cavity. However, due to the small gap and significant frictional resistance between the outriggers and the cavity, installers need to use a heavy hammer to strike the outriggers to increase the pushing force and ensure they are fully inserted. This method not only requires considerable manpower but also causes dents or deformation on the outrigger surface, affecting assembly accuracy. Because it requires multiple people working together, manually pushing in the outriggers is time-consuming and has a low success rate, easily delaying the assembly process and impacting the overall production schedule of the truck-mounted crane. Directly using the overhead crane to pull the outriggers at an angle and forcibly pull them into the outrigger cavity not only violates the overhead crane operating procedures and can easily lead to abnormal stress on the overhead crane cables, but may also cause the overhead crane to tilt or the outriggers to deform, posing a significant safety hazard.

[0003] Therefore, how to provide a device that can accurately, safely and efficiently push the outriggers into the outrigger cavity, effectively reducing the burden of manual installation, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0027] Furthermore, the auxiliary push assembly, disposed on the upper end of the first translation member, includes: an auxiliary push drive member, an auxiliary push guide rod, and a push plate disposed at the front end of the auxiliary push guide rod;

[0028] The auxiliary push drive component drives the push plate to extend and retract along the auxiliary push guide rod in a direction parallel to the first slide rail.

[0048] This utility model provides a leg-mounting device, see reference. Figure 1 It includes: a moving component 1, a first slide rail 2, and an auxiliary pushing component 3;

[0049] The movable component 1 is movably mounted on the first slide rail 2 and supports one end of the support leg 4 to be installed.

[0050] The auxiliary push component 3 is telescopically mounted on the movable component 2 and rests against the rear side of the receiving mounting leg 4.

[0051] This embodiment provides a leg-mounting device for pushing a leg into a leg cavity to complete the leg installation. Taking the installation of an "L"-shaped leg as an example, the "L"-shaped leg is first moved onto the moving component. The shorter end of the "L"-shaped leg rests on the moving component, its rear side abuts against the auxiliary pushing component, and the longer end rests on the entrance of the leg cavity, initially aligning the installation direction. Then, guided by a first slide rail, the position of the moving component is adjusted to axially align the leg with the leg cavity, ensuring no misalignment occurs during subsequent pushing. Finally, under the combined action of the moving component and the auxiliary pushing component, a stable pushing force is applied to the rear side of the leg, pushing it stably and evenly into the leg cavity. By using a mechanical pushing method instead of manual pushing, the inefficient operation of multiple people is avoided, the risk of manual installation is reduced, and the installation process is faster and smoother. The first slide rail guidance and the moving component adjustment simplify the leg alignment process, reduce repeated adjustments due to misalignment, and shorten the installation time. The first slide rail constrains the direction of movement, ensuring that the outrigger does not deviate during the process of pushing it into the outrigger cavity, thus improving assembly accuracy. The auxiliary pushing component, in conjunction with the moving component, provides uniform thrust, preventing damage or deformation of the outrigger surface due to uneven external forces. In summary, this invention provides an outrigger insertion device that accurately, safely, and efficiently pushes the outrigger into the outrigger cavity, effectively reducing the burden of manual installation.

[0052] Preferred, Reference Figure 1 The moving component 1 includes: a first-direction translation component 11, a second-direction translation component 12, and a second-direction translation component 13;

[0053] The first direction translation component 11 is movably mounted on the first slide rail 2;

[0054] The second direction translation member 12 is disposed on the first direction translation member 11 and can move vertically up and down along the first slide rail 2.

[0055] The third direction translation component 13 is disposed on the second direction translation component 12 and can move along the first slide rail 2 in the horizontal and vertical directions.

[0056] In this embodiment, a first-direction translation component, mounted on a first slide rail, can move horizontally along the first slide rail (equivalent to the X-axis) to adjust the outrigger's front-to-back direction, ensuring the outrigger end aligns with and is inserted into the outrigger cavity. A second-direction translation component, mounted on the first-direction translation component, can move vertically along the first slide rail (equivalent to the Z-axis) to adjust the outrigger height, ensuring the outrigger end face is at the same height as the inlet of the outrigger cavity. A third-direction translation component, mounted on the second-direction translation component, can move left-right along the horizontal-vertical direction of the first slide rail (equivalent to the Y-axis) to adjust the outrigger's alignment in the lateral direction. Through this three-way translation structure, the moving assembly can achieve omnidirectional adjustment in front-to-back, left-to-right, and up-to-down directions, ensuring complete alignment of the outrigger end face with the outrigger cavity, improving installation accuracy and reducing installation errors. This avoids the time-consuming technical problem of large outrigger alignment deviations in existing installations, requiring repeated outrigger movements or even re-hoisting.

[0057] Preferred, Reference Figure 2 The first slide rail 2 includes: a first slide rail 21 and a second slide rail 22 that are parallel to each other;

[0058] The first direction translation component 11 includes: a first frame 111, a first drive component 112 disposed on the frame, and first sliders 113 symmetrically disposed on both sides of the frame;

[0059] The first driving component 112 drives the first slider 113 to move within the first slide rail 21 and the second slide rail 22, thereby causing the first frame 111 to translate on the first slide rail 2.

[0060] The second directional translation component 12 is mounted on the first frame 111.

[0061] In this embodiment, the first and second slide rails are parallel to each other and serve as guide tracks for the first slider, ensuring that the first-direction translation component moves along a predetermined direction. The first frame is mounted on the first slider and is powered by a first driving component, driving the first slider to move along the first and second slide rails, thereby achieving horizontal translation of the first frame. This ensures that the first frame and the support leg to be installed move smoothly along a fixed direction without deviation. The use of parallel first slide rails and a double-slider structure effectively reduces guiding errors, ensuring precise movement of the equipment in the first direction and preventing wobbling or deviation.

[0062] Preferred, Reference Figure 1 and Figure 3 The second direction translation component 12 also includes: a second drive component 121, a lead screw 122, and a second frame 123 connected in sequence;

[0063] The lead screw 122 is arranged to pass through the first frame 11 and the auxiliary push assembly 3 along the vertical direction of the first slide rail 2.

[0064] The second drive component 121 drives the second frame 123 to move up and down along the lead screw 122.

[0065] In this embodiment, the second directional translation component, through the cooperation of the second drive component, the lead screw, and the second frame, employs lead screw transmission. Through high-precision helical motion, it ensures that the second frame and the outrigger move smoothly and controllably up and down along a fixed vertical direction, avoiding vibration or displacement errors, and making vertical pushing and adjustment more precise. The lead screw passes through the first frame and the auxiliary push assembly, meaning that the entire lead screw and L-shaped outrigger can always remain on a fixed vertical line during up and down movement, preventing tilting, swaying, or jamming caused by uneven force. It also provides stable support for the heavy outrigger and prevents structural deformation or damage caused by changes in the outrigger's center of gravity.

[0066] Preferred, Reference Figure 1 and Figure 4 The third translation member 13 includes: a third driving member, a second slide rail 131, and a support slide 132 that can be moved and disposed on the second slide rail;

[0067] The second slide rail 131 is horizontally perpendicular to the first slide rail 2 and is located on the front side of the second frame 123.

[0068] The third driving component drives the support slide 132 to move back and forth on the second slide rail;

[0069] Support slide 132 is used to support the outrigger 4 to be installed.

[0070] In this embodiment, the third driving component drives the support slide to move back and forth on the second slide rail (Y-axis), thereby moving the outrigger to be installed back and forth. Combined with the aforementioned second-direction translation component (Z-axis) driven by the first slide rail (X-axis) and a lead screw, this achieves precise translation of the equipment in the X, Y, and Z directions. Furthermore, the first, second, and third-direction translation components operate independently, precisely adjusting the translation amount in different directions. On one hand, this reduces installation errors, improves positioning accuracy, and prevents the outrigger from jamming during installation; on the other hand, it eliminates the need to replace the main structure—simply adjusting the position of the support slide allows for adaptation to the installation requirements of outriggers of different specifications, thus expanding the applicability of the device.

[0071] Preferred, Reference Figure 1 and Figure 5 The supporting slide 132 includes: a base plate 132a, a side plate 132b, and a low plate 132c;

[0072] The base plate 132a has a groove at the bottom corresponding to the second slide rail 131, and supports one end of the support leg 4 to be installed at the top.

[0073] The enclosure 132b includes: left and right side enclosures on both sides of the base plate 132a and a rear enclosure at the rear end, and partially abuts against the sides and rear of one end of the support leg 4 to be installed.

[0074] The low plate 132c is set at the front end of the base plate 132a, and its height is less than that of the surrounding plate 132c. It partially abuts the front side of one end of the receiving and installation support leg 4.

[0075] In this embodiment, the base plate of the support slide has a groove at its bottom that cooperates with the second slide rail, allowing the support slide to move smoothly along the second slide rail and further improving the accuracy of translation. The top of the base plate of the support slide supports the ends of the outriggers. The surrounding plate of the support slide forms a three-sided enclosed support structure on both sides and the rear end, providing stable support for the outriggers on both sides and the rear end. The height of the lower plate is lower than that of the surrounding plate, which facilitates the movement of the outriggers before installation and the movement of the outriggers after installation, and also provides reasonable front end limit during installation. The surrounding plate, top plate, base plate, and auxiliary pushing assembly combine to form a stable support. At the same time, it facilitates the movement of the outriggers in and out, greatly improving installation efficiency.

[0076] Preferred, Reference Figure 1 , Figure 2 and Figure 4 The auxiliary push assembly 3 is disposed on the upper end of the first translation component 11 and includes: an auxiliary push drive component 31, an auxiliary push guide rod 32 and a push plate 33 disposed at the front end of the auxiliary push guide rod 32;

[0077] The auxiliary push drive component 31 and the drive push plate 33 extend and retract on the auxiliary push guide rod 32 in a direction parallel to the first slide rail.

[0078] Push plate 33 abuts against the upper part of the rear side of one end of the receiving and mounting support leg 4.

[0079] In this embodiment, an auxiliary push drive unit drives a push plate that abuts against the upper rear side of the outrigger. The push plate extends and retracts along the auxiliary push guide rod in a direction parallel to the first slide rail, combining with the support slide and the first directional translation component to achieve stable propulsion of the outrigger. During the installation process, the support slide provides bottom support to prevent the outrigger from tilting or deviating, while the push plate acts on the upper rear side of the outrigger, optimizing the force distribution point and allowing the outrigger to smoothly enter the outrigger cavity in the correct direction, greatly improving installation accuracy and efficiency. Furthermore, the auxiliary push drive unit precisely controls the extension and retraction of the push plate to finely adjust the pushing direction of the outrigger, ensuring that the outrigger smoothly enters the outrigger cavity along the correct trajectory without deviation or jamming.

[0080] Preferred, Reference Figure 1 and Figure 6 The outrigger insertion device is characterized in that it further includes: a pull-back assembly 5 disposed at the upper end of the first frame 111;

[0081] The pullback assembly 5 includes: a flexible strap 51 and pullback mounting members 52 symmetrically arranged on both sides of the first frame 111;

[0082] The soft strap 51 is tied to the inner right angle position of the outrigger 4 to be installed, and both ends are detachably set on the reverse installation part 52.

[0083] In this embodiment, a retraction component is added to the outrigger installation device. If the outrigger gets stuck, misaligned, or fails to install during the pushing process, a soft strap on the retraction mounting component can pull the outrigger backward, removing it from the outrigger cavity for readjustment or replacement. Once the outrigger is removed from the cavity, only the soft strap needs to be removed, without interfering with subsequent alignment, installation, or movement. In existing technologies, if the outrigger gets stuck, manual hammering or mechanical pulling is usually required, which can easily damage the outrigger surface or cavity structure. This device uses a soft strap for flexible pulling, allowing the outrigger to be smoothly removed without damage, improving the controllability and safety of the installation process. The soft strap is tied at a right angle inside the outrigger, with a reasonable force point that does not affect the outrigger's structure. It is also suitable for outriggers of different sizes, enhancing the equipment's versatility.

[0084] Preferred, Reference Figure 6 The reverse-pull-out mounting component 52 has multiple spaced-apart adjustment columns 52a on one side;

[0085] A limit plate 52b is provided at the end of the adjusting column 52a;

[0086] The flexible strap 51 is symmetrically attached to the adjusting column 52a at both ends.

[0087] In this embodiment, the adjusting columns are arranged in a multiple-spaced pattern, allowing for flexible selection of the flexible strap's attachment points and adjustment of its length to accommodate the installation requirements of outriggers of different specifications. Limiting plates are installed at the ends of the adjusting columns to ensure the flexible strap does not slip unexpectedly under stress, maintaining its stability even when subjected to significant tension during pullback. The flexible strap is symmetrically attached to the adjusting columns, ensuring even force distribution during pullback and preventing outrigger tilting or twisting due to uneven force on one side, thus ensuring the outrigger exits the outrigger cavity in the correct direction. The spaced adjusting columns, limiting plates, and symmetrically attached flexible straps significantly improve the pullback assembly's adaptability, safety, stability, and ease of operation.

[0088] A crane installation device includes any of the above-mentioned outrigger mounting devices.

[0089] In this embodiment, a crane installation device is provided, which includes any of the above-mentioned outrigger installation devices, enabling efficient and safe installation of crane outriggers. This solves the technical problems of low reliability, significant safety hazards, and low installation accuracy caused by reliance on manual handling and pushing during traditional crane outrigger installation. It is applicable to the installation of crane outriggers of different specifications, significantly reducing the cost of crane installation.

[0090] The aforementioned crane installation equipment is based on the aforementioned outrigger mounting device, and its technical effects and features are combined in a way that will not be elaborated upon here. The above embodiments merely illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
