Description

Technical Field

[0001] This utility model relates to the field of crane assembly technology, specifically to a pad tooling for a platform crane. Background Technology

[0002] In large-scale engineering construction, platform cranes are crucial heavy lifting equipment. To ensure the stability and safety of the crane when lifting heavy objects, its outriggers must be reliably supported on the deck or foundation using piers. Currently, the industry commonly uses two main traditional pier methods: The first method involves using loose steel or wooden blocks or plates, stacking and layering them. While this method is simple to obtain materials for, it has significant drawbacks: First, the stability of multi-layered blocks is poor, and they are prone to displacement and collapse under the dynamic load of the crane or ground micro-vibrations, posing serious safety hazards; second, each installation and dismantling requires repeated manual handling, alignment, and adjustment, which is cumbersome, time-consuming, labor-intensive, and extremely inefficient; finally, the loose blocks are not standardized in size, making management inconvenient, and they are prone to deformation after long-term use, affecting the levelness of the supporting plane; The second method involves fabricating large, integral welded piers. While this method solves the stability problem, it brings new drawbacks: its structure is bulky, making it extremely inconvenient to move and transport, requiring the cooperation of other lifting equipment, and its flexibility is extremely poor; at the same time, it is a one-time design and cannot be flexibly adjusted according to the height of the outriggers or the unevenness of the ground, resulting in low versatility; in addition, it has high manufacturing costs and occupies a large storage space.

[0003] For example, patent application number CN202111085229.6, published on March 24, 2023, discloses a foundation structure for an offshore crane and its construction method. The foundation structure for the offshore crane includes a support device and an installation platform. The support device includes multiple support pipe piles and a connecting component for connecting two adjacent support pipe piles. One end of the support pipe pile is buried in the seabed and the other end extends out of the sea surface. The support pipe pile is connected to the platform foundation structure of the offshore concrete mixing plant. The installation platform is connected to multiple support pipe piles respectively for fixing and installing the crane.

[0004] The support devices described in the above literature are mainly connected by support pipe sleeves and connecting sleeves, which requires a lot of welding operations, making disassembly and assembly difficult. Furthermore, the same support device is used for the same platform crane, but different positions of the platform crane have different support height requirements. If multiple support devices of different heights are used to achieve the support, it will lead to the need to manufacture too many support devices, resulting in excessive costs. Moreover, it cannot reliably adjust for slight height differences due to production variations, resulting in poor adaptability. Utility Model Content

[0005] This utility model provides a support block tooling for platform cranes, which can select a suitable connection structure according to the type of crane and working requirements, and is simple to install and has strong structural stability.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a platform crane support fixture, set between the working platform and the bottom of the crane, includes a support body, a first support member, and a second support member. Two or more support bodies are provided at the bottom of the crane's slewing bearing. A support body and a first support member are provided at the front end of the crane. The first support member is located at the upper end of the support body, and its height is adjustable, with the top of the first support member being higher than the upper end of the support body located at the bottom of the slewing bearing. A support body and one or more second support members are provided at the bottom of the crane's slewing base. The number of second support members is determined by the gap between the support body located at the bottom of the slewing base and the bottom of the slewing base.

[0007] The above setup utilizes different support effects at various locations on different parts of the crane, such as the front end, slewing bearing, and slewing base. For example, the front end of the crane is supported by a pier body and a first support member, with the upper part of the first support member being higher than the upper part of the pier body. The height of the first support member is easily adjustable, allowing for adjustment of the crane's front end height without needing to adjust the height of the pier body itself, which could compromise overall strength. Furthermore, by adjusting only the height of the first support member, the height of the pier body can be easily adjusted, whereas adjusting the entire pier body is not feasible. The main body of the pier needs a certain weight to ensure support strength, making it inconvenient to move the entire pier body. In addition, multiple pier bodies are set at the bottom of the slewing bearing of the crane for support. On the slewing base above the slewing bearing, a support structure is formed by setting pier bodies and second support members. When the gap between the slewing bearing and the slewing base is different under different working conditions or when different balance conditions occur when placed on the platform, the balance of the entire crane can be slightly adjusted by changing the number of second support members at the gap, which is convenient for adjustment. In addition, since pier bodies are set at three support points, the bottom support strength and stability of the support are ensured.

[0008] Furthermore, the first support member includes a first support base, on which a first support rod and a second support rod are disposed. One end of the first support rod is detachably connected to one end of the second support rod, and a first support platform is disposed on the other end of the second support rod. Fixing holes are disposed on the first support base and the first support platform.

[0009] The above configuration allows for easy adjustment of the height of the first support member through a detachable connection between the first and second support rods. Fixing holes are provided on the first support base and the first support platform to fix the first support member to the main body of the pier and the front end of the crane, respectively.

[0010] Furthermore, one end of the first support rod is sleeved on one end of the second support rod, and one or more first adjustment holes are correspondingly provided on the first support rod and the second support rod along the length direction of the first support rod. One or more first adjustment rods are provided in the first adjustment holes, and a first fixing hole is provided on the free end of the first adjustment rod.

[0011] The above configuration allows for easy adjustment by providing multiple first adjustment holes on the first support rod, with the first support rod sleeved on the outside of the second support rod, and by inserting the first adjustment rod into different first adjustment holes.

[0012] Furthermore, one end of the first support rod is sleeved on one end of the second support rod, and the one end of the first support rod and the one end of the second support rod are welded together.

[0013] The above setup achieves a detachable connection by welding one end of the first and second support rods, ensuring the strength of the connection.

[0014] Furthermore, the second support member includes one or more second support blocks, and the second support blocks are provided with second fixing holes arranged along the thickness direction of the second support blocks.

[0015] The above configuration involves providing a second fixing hole on the second support block, through which the connection between the second support member and the rotary base is achieved.

[0016] Furthermore, a third support is provided between the second support and the main body of the pad located below the second support. The second support includes a third support base, on which a third support rod and a fourth support rod are provided. One end of the third support rod is detachably connected to one end of the fourth support rod, and a third support platform is provided on the other end of the third support rod. A third fixing hole is provided on the third support base and the third support platform.

[0017] The above setup involves adding a third support between the second support and the main body of the pier. This third support allows for large-scale adjustment when the gap between the slewing base and the slewing bearing is too large. After adjusting the large gap, the second support block can then be used for small-scale fine-tuning.

[0018] Furthermore, one end of the third support rod is sleeved on one end of the fourth support rod, and one or more second adjustment holes are provided on the third support rod and the fourth support rod along the length direction of the second support rod, and one or more second adjustment rods are provided in the second adjustment holes, and a fourth fixing hole is provided on the free end of the second adjustment rod.

[0019] The above setup allows for detachable connection and height adjustment of the third support component by having the third support rod sleeved on the fourth support rod.

[0020] Furthermore, one end of the third support rod is sleeved on one end of the fourth support rod, and the one end of the third support rod and the one end of the fourth support rod are welded together.

[0021] In the above configuration, the third support component is connected by welding to ensure connection strength.

[0022] Furthermore, the main body of the pier located below the slewing bearing, the main body of the pier located below the first support member, and the main body of the pier located below the second support member have the same structure and height.

[0023] The above setup ensures consistent support strength at the bottom of the three support points by making the height and structure of the piers at the three support points the same.

[0024] Furthermore, the second support block is a pad made of nylon material.

[0025] The above setup, using pads made of nylon material, reduces the weight of the entire second support component and also makes it easier to insert the second support block into the gap. Attached Figure Description

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] Example 1.

[0040] like Figures 1 to 7 As shown, a platform crane support 2 is set between the working platform and the bottom of the crane 1, so that the support 2 can lift the crane 1, and inspect the base of the crane 1 while protecting the working platform. The crane 1 includes a crane front end 11, a slewing base 13 and a slewing bearing 12 located below the slewing base 13. The crane front end 1 can be a structure such as a cab.

[0041] like Figure 5 and Figure 6As shown, the pad support fixture includes a pad support body 21, a first support member 22, and a second support member 23. The bottom of the slewing bearing 12 of the crane 1 is provided with two or more pad support bodies 21. The front end 11 of the crane is provided with a pad support body 21 and a first support member 22. The first support member 22 is located at the upper end of the pad support body 21. The height of the first support member 22 is adjustable, and the height of the top of the first support member 22 is higher than the height of the upper end of the pad support body 21 located at the bottom of the slewing bearing 12. The bottom of the slewing base 13 of the crane is provided with a pad support body 21 and one or more second support members 23. One or more second support members 23 are located on the pad support body 21. The number of second support members 23 is determined by the gap between the pad support body 21 located at the bottom of the slewing base 13 and the bottom of the slewing base 13.

[0042] like Figure 3 and Figure 6 As shown, the first support member 22 includes a first support base 221, a first support rod 222 and a second support rod 223 are provided on the first support base 221, one end of the first support rod 222 is detachably connected to one end of the second support rod 223, and a first support platform 224 is provided on the other end of the second support rod 222. Fixing holes (not shown in the figure) are provided on the first support base 221 and the first support platform 224.

[0043] In this embodiment, one end of the first support rod 222 is sleeved on one end of the second support rod 223, and one end of the first support rod 222 and one end of the second support rod 223 are welded together. The first support base 221 and the upper end of the pier body 21, and the second support platform 224 and the bottom of the front end 11 of the crane are all connected by bolts passing through fixing holes. The first support rod 222 and the second support rod 223 are hollow rod structures. In order to prevent the first support rod 222 and the second support rod 223 from rotating relative to each other, the cross-section of the first support rod 222 and the second support rod 223 can be set to square.

[0044] like Figure 4 and Figure 7 As shown, the second support member 23 includes one or more second support blocks. The second support block is provided with a second fixing hole 231 arranged along the thickness direction of the second support block. In this embodiment, there are three second support members 23, and the second fixing holes on the three second support members 23 are aligned and fixedly connected by bolts. The second support block is a pad made of nylon material. The pad made of nylon material can reduce the weight of the entire second support member and also facilitate the insertion of the second support block in the gap.

[0045] like Figure 7As shown, a third support member 24 is also provided between the second support member 23 and the pad body 21 located below the second support member 23. The second support member 24 includes a third support base 241. A third support rod 242 and a fourth support rod 243 are provided on the third support base 241. One end of the third support rod 242 is detachably connected to one end of the fourth support rod 243. A third support platform 244 is provided on the other end of the third support rod 242. A third fixing hole (not shown in the figure) is provided on the third support base 241 and the third support platform 243.

[0046] In this embodiment, one end of the third support rod 242 is sleeved on one end of the fourth support rod 243, and one end of the third support rod 242 and one end of the fourth support rod 243 are welded together. The third support rod 242 and the fourth support rod 243 are hollow rod structures. In order to prevent the third support rod 242 and the fourth support rod 243 from rotating relative to each other, the cross-section of the third support rod 242 and the third support rod 243 can be set to square.

[0047] The main body 21 of the pier located below the slewing bearing 12, the main body 21 of the pier located below the first support member 22, and the main body 21 of the pier located below the second support member 23 have the same structure and height. In this embodiment, the main body 21 of the pier is a square main body structure formed by the four side plates and the surrounding main body, which is the prior art and will not be described in detail here.

[0048] The working principle of this utility model is as follows: By setting different support effects at corresponding positions on different components of the crane 1, such as the crane front end 11, the slewing bearing 12, and the slewing base 13, for example, the crane front end 11 is supported by the pier body 21 and the first support member 22, and the upper end of the first support member 22 is higher than the upper end of the pier body 21. Furthermore, the height of the first support member 22 is easily adjustable. This allows for adjustment of the height of the crane front end 11 according to its different heights, without needing to adjust the height of the pier body 21, which would compromise the overall strength. Additionally, by adjusting only the height of the first support member 22, it is convenient to adjust the height of the entire pier body 21 without affecting its overall strength. Adjustment is possible because the main body 21 of the support needs a certain weight to ensure support strength, making it inconvenient to move the entire main body 21. In addition, multiple main bodies 212 are set at the bottom of the slewing bearing 12 of the crane for support. On the slewing base 13 above the slewing bearing 12, a support structure is formed by setting the main bodies 21 and the second support member 23. When the gap between the slewing bearing 12 and the slewing base 13 is different under different working conditions or when different balance conditions occur when placed on the platform, the balance of the entire crane can be slightly adjusted by changing the number of the second support member 23 at the gap, which facilitates adjustment. In addition, since the main bodies are set at the three support points, the bottom support strength and the stability of the support can be ensured.

[0049] Example 2.

[0050] The difference between this embodiment and Embodiment 1 is that the second and third support members have different detachable structures.

[0051] like Figure 8 and 11 As shown, one end of the first support rod 222 is sleeved on one end of the second support rod 223, and one or more first adjustment holes 2221 are provided on the first support rod 222 and the second support rod 223 along the length direction of the first support rod 222. One or more first adjustment rods 2222 are provided in the first adjustment holes 2221, and a first fixing hole 2223 is provided on the free end of the first adjustment rod 2222.

[0052] Similarly, one end of the third support rod 242 is sleeved on one end of the fourth support rod 243, and one or more second adjustment holes (not shown in the figure) are provided on the third support rod 242 and the fourth support rod 243 along the length direction of the third support rod 242. One or more second adjustment rods are provided in the second adjustment holes, and a fourth fixing hole is provided on the free end of the second adjustment rod.

[0053] This allows the first support rod 221 and the second support rod 222 to be inserted into the first adjustment hole 2221 through the first adjustment rod, and then a pin can be inserted into the first fixing hole 2223 of the first adjustment rod 2222 to achieve a fixed and detachable connection, which facilitates the detachable connection.
