Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically, to an adjustable-height crane outrigger locking device. Background Technology

[0002] Crane outriggers are a key component of cranes, providing additional stability and support while the crane is in operation. They help distribute the weight of the crane and its load over a larger area of ​​the ground, thereby reducing pressure on the ground and preventing the crane from tipping over during operation.

[0003] Existing crane outriggers typically only support a single point on one side. This means that when the crane is on uneven ground or requires more complex operations, this simple support method may not provide sufficient stability and safety. Especially when performing heavy-load tasks or working in complex environments, a single support point may cause the crane to tilt or even overturn, posing a potential safety hazard to operators and other on-site workers. At the same time, some existing crane outriggers cannot adjust their height according to different working environments and needs, nor can each outrigger be locked individually. This limits the crane's application range in different terrain conditions. For example, when working in mountainous areas or narrow urban spaces, if the height of the outriggers cannot be flexibly adjusted, it is difficult to ensure that the crane is in a level position, thus affecting the accuracy and efficiency of lifting operations.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adjustable height crane outrigger locking device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An adjustable-height crane outrigger locking device includes two support frames. A first adjustment component is disposed inside each support frame, and a controller is disposed inside the first adjustment component. A second adjustment component is disposed at the upper end of each support frame. A slide rail is disposed between the first adjustment components, and a lifting device is slidably connected to the slide rail. Two casters are disposed at the bottom end of each support frame. The second adjustment component includes multiple adjustment frames, which are symmetrically fixedly disposed at the upper end of the support frame. A motor is disposed at the upper end of each adjustment frame. The output shaft of the motor is connected to a threaded rod via a coupling. One end of the threaded rod extends into and connects to the interior of the adjustment frame.

[0008] Furthermore, in order to better ensure the height adjustment of the crane, the first adjustment component includes an adjustment groove, which is opened inside the support frame. The controller is fixedly installed on the inner wall of the adjustment groove. An electric cylinder is installed inside the support frame through a fixed seat, and an adjustment seat is installed at the output end of the electric cylinder.

[0009] Furthermore, to better ensure the stability of height adjustment, a mounting base is slidably connected inside the adjustment seat, and the mounting base is fixedly set on one side of the fixed base. A scissor-type adjustment frame is connected to the mounting base through a rotating shaft one, and one side of the scissor-type adjustment frame is connected to one side of the adjustment seat through a rotating shaft two.

[0010] Furthermore, to better ensure the height adjustment effect of the outriggers, one end of the scissor-type adjustment frame is connected to an adjustment gear and a mounting block. An adjustment rod is bolted to the mounting block, and the slide rail is fixedly installed on the upper end of the adjustment rod.

[0011] Furthermore, in order to better ensure support at multiple positions on one side of the crane, an adjusting block is threadedly connected to the threaded rod, and the adjusting block is adapted to the adjusting frame. A base is provided between the adjusting blocks, and a placement cavity is opened inside the base. A second motor is installed at the upper end of the base through a fixing frame, and a drive gear is provided on the output shaft of the second motor.

[0012] Furthermore, to better ensure the adjustment effect, the edge of the driving gear is connected to the driven gear through the base, the driven gear is provided with a rotating block, and the upper end of the rotating block is provided with a spiral rail.

[0013] Furthermore, to better ensure the locking effect of the outriggers, an adjusting plate is slidably connected to the upper end of the spiral rail, a hydraulic cylinder is provided at one end of the adjusting plate, a support seat is symmetrically arranged on the hydraulic cylinder, an electric cylinder II is provided on the support seat, and a locking block is provided at the moving end of the electric cylinder II.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting the second adjustment component, the crane outrigger height can be flexibly adjusted and the single-side multi-point support capability is realized, which significantly improves the adaptability and operational safety of the equipment. The screw rod is driven by the motor to rotate, and the screw-connected adjustment block moves up and down along the adjustment frame, thereby changing the height of the outrigger. This ensures that the crane can maintain a horizontal state on uneven ground or in different terrain conditions, optimizing the accuracy and efficiency of lifting operations. In addition, it is convenient to adjust and lock each outrigger independently, so that the crane can be supported in multiple positions on one side, increasing the stability during operation and reducing the risk of overturning. At the same time, the multi-point and multi-directional support capability also expands the application range of the crane in complex environments, such as construction in mountainous areas or narrow urban spaces, providing operators with a wider range of operational flexibility and higher safety assurance.

[0016] (2) By setting the first adjustment component, the crane can be provided with a height adjustment function, which significantly enhances the adaptability and operational flexibility of the equipment. The first adjustment component integrates a controller and an electric cylinder. The electric cylinder drives the adjustment seat to move up and down, and combined with the scissor-type adjustment frame, it can achieve precise adjustment of the crane's operating height.

A motor 602 is mounted on the upper end of each adjustment frame 601. The output shaft of the motor 602 is connected to a threaded rod 603 via a coupling.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to adjust the height of the crane outriggers, the operator controller 9 starts the motor 602. The motor 602 drives the threaded rod 603 to rotate through the coupling. The threaded rod 603 and the adjusting block 604 are threadedly connected. Therefore, when the threaded rod 603 rotates, the adjusting block 604 will move up and down along the threaded rod 603. The up and down movement of the adjusting block 604 changes the position of the base 605, thereby realizing the adjustment of the overall height of the outriggers. Each outrigger can be adjusted independently, so that the crane can maintain a level state on uneven ground. For special terrain or operation requirements, single-side multi-point support can be achieved by controlling each outrigger individually, improving the stability and safety of the equipment. After the height adjustment is completed... The controller 9 starts the motor 606, and the output of the motor 606 drives the drive gear 607 to rotate. The drive gear 607 drives the driven gear 608 to rotate, which in turn causes the rotating block 609 and the spiral rail 610 to rotate together. This causes the adjusting plate 611 to slide and adjust, thereby expanding the support area of ​​the outrigger to adapt to different working conditions. In order to ensure that the position of the outrigger remains fixed, the moving end of the electric cylinder 613 pushes the adjusting plate 611 to slide along the spiral rail 610. The electric cylinder 613 is responsible for pushing the locking block 614 to the designated position of the moving end of the hydraulic cylinder 612 for fixing. Once the locking block 614 is in place, it can effectively prevent any further movement of the hydraulic cylinder 612, ensuring the stability of the outrigger during operation.

[0039] When the crane height needs to be adjusted, the operator can control it through the controller 9, which controls the extension and retraction of the electric cylinder 201. When the moving end of the electric cylinder 201 extends or retracts, it drives the connected adjusting seat 202 to move. As the adjusting seat 202 moves, the scissor-type adjusting frame 204 is assisted in adjustment (i.e., unfolding or retracting) through the rotating shaft 1 and rotating shaft 2. One end of the scissor-type adjusting frame 204 is connected to the adjusting gear 205 and the mounting block 206. These components ensure the smooth movement of the scissor-type adjusting frame 204 and transmit the vertical force to the structure above. The adjusting rod 207 on the mounting block 206 moves up and down with the change of the scissor-type adjusting frame 204. As the adjusting rod 207 rises or falls, the height of the entire slide rail 3 and the lifting equipment 4 sliding on it will also increase or decrease, providing the crane with a height adjustment function, which significantly enhances the adaptability and operational flexibility of the equipment.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
