Description

Technical Field

[0001] This utility model relates to the field of cranes, and in particular to a multifunctional support for cranes that can carry pads, hooks and sleepers. Background Technology

[0002] When a crane is in operation, its main structure needs to withstand significant forces. To ensure its stability during operation, flat outrigger pads need to be placed under the outriggers to increase the contact area between the crane and the ground, reducing the pressure per unit area. However, the outrigger pads are heavy and have a large area, so their relocation requires a separate transport vehicle, increasing construction costs and crane preparation time, and affecting operational efficiency. Furthermore, a survey of customer needs revealed that customers desired the ability to carry a crane lifting hook and sleepers during relocation, which would be convenient and reduce transportation costs. Considering customer ease of use, a multi-functional fixed support structure was created by combining the functions of carrying outrigger pads, crane hooks, and sleepers.

[0003] Currently, there are two methods for transporting outrigger pads in the crane industry: one method involves placing the outrigger pads on a separate transport vehicle, which moves with the crane. This method meets the needs of outrigger pad transportation and relocation, but requires a separate transport vehicle, increasing transportation and relocation costs and reducing work efficiency. The other method involves designing a fixed bracket at the rear end of the crane, placing the outrigger pads on this bracket, and using the fixed bracket structure to limit the outrigger pads in all directions, ensuring stability and reliability during transportation. Currently, hooks and sleepers are generally transported using dedicated flatbed trucks, as there is no space or location on the crane body to place and secure hooks and sleepers.

[0004] Existing technologies, such as "Crane, Outrigger Pad Transfer Equipment and Method" (application number 202211400387.0), involve a crane with a bracket detachably connected to the rear of the crane body, and limiting protrusions on the bracket, which can be used to accommodate outrigger pads. It mainly includes a support body, a limiting and fixing mechanism, and a connecting mechanism. The main structure is welded from reinforcing ribs and transverse diaphragms, providing a support surface for the placement of the outrigger pads. The limiting and fixing mechanism is a flat plate with a certain taper, which protrudes to a certain height relative to the upper surface of the pad support. This serves to guide the placement of the outrigger pads and prevent the pads from sliding backward on the upper surface of the support. However, this limiting mechanism only directly limits the first outrigger pad. To utilize its limiting function during the transport of outrigger pads, this pad fixing support structure needs to be used with outrigger pads of a specific structure. Furthermore, the lateral limiting of the outrigger pads is mainly achieved by connecting ropes to hooks on both sides. The connecting mechanism mainly refers to the part that connects the pad bracket to the frame. The main connection method is pin. When the pad needs to be transported with the vehicle, the pad bracket can be fixed to the rear of the frame by fastening the pin. Then the pad is placed on top of the pad bracket, so that the pad can be transported with the vehicle.

[0005] Due to the limited space on the crane frame, existing technologies have designed pallet supports that can carry pallets for relocation in order to make full use of the space. However, there is no dedicated space for the hook and sleepers, and special transport vehicles are often required to transport the hook and sleepers. Therefore, existing technologies mainly have the following problems: (1) Existing pallet supports have a single function and can only carry pallets for relocation; (2) There is no dedicated space for the crane hook and sleepers, and special transport vehicles are required for transportation; (3) There is still room for improvement in the space utilization and transportation efficiency of cranes.

[0017] This utility model discloses a multi-functional support for cranes that can carry a pad, hook, and sleepers. It includes a pad fixing support body 1, a hook fixing support 2, a sleeper connecting support 3, a connecting pin 4, a washer 5, a retaining clip 6, and a fixing pin 7. The pad fixing support body 1, the hook fixing support 2, and the sleeper connecting support 3 are arranged sequentially from top to bottom. The pad fixing support body 1 is connected to the external frame through the connecting pin 4, and the connecting pin 4 is provided with a washer 5 and a retaining clip 6. The hook fixing support 2 is connected to the hook 9 through the fixing pin 7, and the hook 9 is provided with a retaining clip 6.

[0018] The main body 1 of this utility model is a flat plate. Two limiting guide blocks 11 are provided on the rear side of the flat plate to restrict the movement of the foot pads 8. The limiting guide blocks 11 correspond to the limiting blocks on the edge of the foot pads 8 for limiting movement. A reinforcing rib plate is provided below the flat plate of the main body 1. Four rectangular steel pipes are used for support below the flat plate, two of which have pin mounting holes. Pins passing through these holes connect the main body 1 of the main body to the external frame. Interfaces for rope binding are provided on both sides of the main body 1 to secure the foot pads 8. Sleepers 10 are placed inside the sleeper connecting bracket 3. The external frame is a crane frame. Example

[0019] This embodiment of the crane uses a multi-functional support that can carry a pad, hook, and sleepers. In its working state, the main body of the fixed support is assembled and connected to the rear of the vehicle frame. Figure 1 As shown, when the multi-functional fixed bracket is in operation, the foot pad 8 is placed above the pad fixing bracket. The foot pad 8 is limited by the limiting guide block 11 welded to the upper part of the bracket body. A similar limiting guide block 11 is also welded to the upper surface of the rear of the frame, which restricts the foot pad 8 from sliding forward. Additionally, this structure includes a bracket interface for carrying the hook and sleepers, allowing it to carry both the pad and the hook 9 and sleepers 10 simultaneously. The detailed structure of this multi-functional support structure for cranes is as follows: Figure 2 , 3 As shown, the specific structural components include a pad fixing bracket body 1, a hook fixing bracket 2, a sleeper connecting bracket 3, a connecting pin 4, a gasket 5, a loop clip 6, and a fixing pin 7.

[0020] The upper surface of the pad fixing bracket body 1 is mainly composed of a flat plate. On the rear side of the flat plate are two limiting guide blocks 11 that restrict the movement of the pad. The limiting guide blocks 11 can cooperate with limiting blocks on the edge of the pad (such as…). Figure 4 To achieve limit positioning, the flat plate has reinforcing ribs underneath, which strengthen the plate. Four rectangular steel pipes support the flat plate from below, two of which are vertical and have pin mounting holes, allowing the main structure of the fixing bracket to be connected to the vehicle frame via pins. Rope binding interfaces are designed on both sides of the bracket for securing the pad. The main function of the pad fixing bracket body 1 is to support the foot pad 8 and connect the hook bracket 2 and the sleeper bracket 3.

[0021] The main function of the hook fixing bracket 2 is to place the hook 9, thereby enabling the hook 9 to be transported together with the vehicle frame.

[0022] The main function of the sleeper support 3 is to hold the sleeper 10 so that the sleeper 10 can be transported with the vehicle.

[0023] The connecting pin 4 is mainly used to connect and fix the pad fixing bracket body 1 to the frame. The pad fixing bracket body 1 has a pin hole through which the connecting pin 4 can pass. The frame has a fixing point welded to the top of the frame, which also has a pin hole. Align the pad fixing bracket with the mounting hole of the frame and use the connecting pin 4 to connect and fix it.

[0024] The function of shim 5 is to limit the relative displacement of the bracket relative to the frame.

[0025] The main function of the U-shaped clip 6 is to prevent the connecting pin 4 from moving left or right and falling out.

[0026] The left and right fixed pins 7 are used to fix the hook 9 to the hook bracket 2 to prevent the hook 9 from moving during transportation.

[0027] The foot pad 8 is a pad that is carried with the vehicle. The pad has been specially modified around its perimeter so that it can be used in conjunction with the pad bracket.

[0028] Hook 9 is used for lifting during operation.

[0029] Sleeper 10 is used to provide support points for the outrigger plate during crane support.

[0030] The main working principle of the multi-functional bracket that can carry pads, hooks and sleepers in this embodiment is as follows: The bracket is lifted by a crane and installed on the rear of the crane frame using a connecting pin. The hook is placed on the hook fixing bracket connected to the pad bracket and fixed to the pad bracket with a pin to prevent the hook from jumping during transportation. Finally, the sleepers are placed on the sleeper bracket.

[0031] Place the pad on the pad fixing bracket, and then pass the pad (e.g., Figure 5 The limiting guide blocks above the support plate restrict the movement of the support plate, enabling the support plate to be transported with the vehicle. It should be noted that the limiting guide blocks on both sides of the support plate are also integrated with the lifting points, providing both limiting and fixing, as well as lifting and transport capabilities. The specific structure is as follows... Figure 5 As shown. When sleepers and foot pads are needed for vehicle support, remove the sleepers or foot pads from the foot pad fixing bracket. When the crane is in normal lifting operation, the hook can be placed on top of the multi-functional bracket, or it can be lifted and used when needed.

[0032] For multi-functional support structures, in operation, their specific implementation requires use in conjunction with crane outrigger pads, hooks, and sleepers. By placing the pads between the limiting guide blocks on the pad fixing bracket, the outrigger pads can be confined within a fixed area on the pad fixing bracket. Figure 7 As shown.

[0033] This utility model integrates a hook mounting bracket structure and a sleeper placement bracket structure into the main body of a pad bracket, enabling simultaneous transport of pads, sleepers, and hooks. The main body of the pad bracket features a limiting guide block structure, and the foot pads also incorporate limiting blocks. Through the cooperation of the pad bracket and the foot pads, the pads are fixed above the bracket, facilitating transport. Based on the shape and size of the hook, a bracket for holding the hook is integrated with the main body of the pad bracket, allowing for the transport of hooks of different sizes. The hook is secured to the bracket with a pin, ensuring safety during transport. A bracket is constructed using the space beneath the pad bracket, allowing sleepers to be placed on top for transport. The pad fixing bracket integrates a connecting bracket for fixing the hook and a connecting bracket for placing the sleepers. This mechanism is welded together with the fixing bracket, allowing the hook and sleepers to be placed on the bracket during vehicle relocation, facilitating transport.

[0034] This utility model allows for flexible disassembly, assembly, and combination, enabling the simultaneous transport of support plates, hooks, and sleepers, maximizing efficiency without affecting the normal operation of the crane. When transporting the support plates, the matching support plates are placed on top of the support body and positioned by guide blocks above them, facilitating convenient, quick, safe, and reliable transport of the support plates alongside the crane. Furthermore, it fully utilizes the rear space of the crane, allowing the hooks and sleepers to be placed at the rear and fixed to the support, providing a new approach for the simultaneous transport of support plates, hooks, and sleepers alongside the crane.
