Description

Technical Field

[0001] The utility model relates to the technical field of crane maintenance tools, in particular to a jacking tool for a slewing platform. Background Art

[0002] With the continuous development of social economy, the requirements for the normal operation and maintenance of equipment in various industries are getting higher and higher. As an important jacking tool, the jack plays an increasingly significant role in crane maintenance equipment. For example, the slewing platform in a crane is relatively heavy. During assembly or maintenance, the equipment needs to be lifted to the required height by a jack, and then the operator should immediately use a support rod for effective support. During maintenance, different support rods are often used due to different required jacking heights. At this time, more measurement and cutting work are required for the support rod to ensure that it is suitable for a specific application length. At this time, a tool for arbitrarily adjusting the height of the support rod is needed. And when multiple support rods may be spliced together instead of just using one support rod during the jacking process, the stability at the connection of the two support rods needs to be ensured, so as to ensure the stability, safety and accuracy of the whole process.

[0003] For example, in the patent document with the patent application number 202121193586.X and the publication date of February 1, 2022, a jacking mechanism for large radar maintenance is disclosed, which includes a base, guide columns, support columns, a jacking bracket and a top plate. Symmetrically distributed guide columns are fixedly connected to the upper surface of the base. A support column fixedly connected is arranged between the guide columns. The top of the support column is fixedly connected with a top plate. A movably connected jacking bracket is arranged between the base and the top plate. The jacking bracket includes a bracket body, a jack and a linkage rod. The jacking bracket is sleeved on the surface of the guide column and is slidably connected with the guide column. There are two jacks which are respectively fixed to the inner sides of the guide columns. The top of the jack is fixedly connected with the bracket body. A linkage rod is fixedly connected between the jacks. By using support columns connected in several sections and cooperating with the bracket body with a jack, it is convenient to lift the support column, and at the same time, it is convenient to install the support column at the bottom of the bracket body, improving the convenience of building the jacking device and reducing the construction difficulty.

[0004] In the above literature, the jack jacks up the support body, driving the support column to move upward. Then, a section of the support column is taken and placed below the support body and connected to the upper support column. The two support columns are fixedly connected through the flange of the mounting hole provided on the support column body. Moreover, the connection between the support column and the jacking mechanism also needs to be achieved through a flange. When connecting, it is necessary to fix the outwardly protruding edge provided on the support column to the edge of the jacking mechanism to achieve the connection. Since the support column needs to be installed on the jacking mechanism, it is impossible to ensure the reliable installation of the support column. Additionally, when connecting the two support columns through a flange, flanges need to be respectively provided on the adjacent support columns, and then the flanges are connected through bolts. During the installation process, since the support column is installed on the flange, it is impossible to align the adjacent flanges, and the operation is complex. Summary of the Invention

[0005] The utility model provides a jacking tooling for a slewing platform, which has a simple structure and is convenient to install.

[0006] To achieve the above object, the technical solution of the utility model is: a jacking tooling for a slewing platform, used to connect a support rod and a jacking mechanism, including a support device. The support device includes a support, and the support includes a support body. A second groove is provided on the support body, and one end of the support column is arranged in the second groove. A fixing hole is provided on the bottom surface of the support body corresponding to the position where the second groove is located. A fixing member is fixedly connected to one end of the jacking mechanism through the fixing hole. A connecting plate is provided at the bottom of the support column, and a connecting hole is provided on the connecting plate. The connecting hole passes through the upper end of the fixing member.

[0007] With the above settings, by providing a second groove on the support body and a fixing hole at the bottom of the groove, when it is necessary to set a support column between the jacking mechanism and the object to be jacked up, the fixing member is passed through the fixing hole and the support is fixed on the jacking mechanism. Then, the connecting hole at the bottom of the support column is passed through the fixing member, and the bottom of the support column is arranged in the second groove, so that the inner side wall of the second groove abuts against the bottom of the support column. In this way, setting the connecting hole on the support column can reduce the weight of the support column, and at the same time, it is also convenient to first install the support on the jacking mechanism and then place the support column. The structure is simple and the installation is convenient.

[0008] Furthermore, it further includes a docking head. The two support rods can be connected through the docking head. First grooves for accommodating one end of the support column are respectively provided at both ends of the docking head, and a support bottom plate is provided between the bottoms of the two first grooves. A first through hole is provided on the support bottom plate.

[0009] With the above settings, multiple support columns can be connected through the adapter, thereby meeting the requirements for different jacking heights. Through the two first grooves on one adapter, the inner side walls of the first grooves restrict the support columns, making it convenient to respectively place one end of two support columns in the first grooves. Then, by providing first through holes on the support plate, support flanges are formed on the inner side walls of the adapter for support, and the weight can be reduced, thus realizing the integrated setting of the adapter and ensuring the support effect.

[0010] Furthermore, the connecting hole and the first through hole are coaxially arranged, and the cross-sectional area of the connecting hole on the support column is smaller than the cross-sectional area of the first through hole.

[0011] With the above settings, by providing a first through hole with a relatively large cross-sectional area, while reducing the weight of the adapter, the connection area between the support plate and one end of the support column is also reduced, preventing the support column from being unable to be reliably and vertically connected in the first groove due to the formation of uneven surfaces on the support bottom plate of the adapter.

[0012] Furthermore, the support device further includes an upper support, which is used to be arranged at one end of the support rod away from the jacking mechanism, and the upper support is detachably connected to one end of the support rod away from the jacking mechanism.

[0013] With the above settings, by arranging an upper support at one end of the support rod away from the jacking mechanism, it is convenient to contact the object to be supported through the upper support.

[0014] Furthermore, the upper support includes an upper support body, on which a third groove is provided, and one end of the support column away from the jacking mechanism is arranged in the third groove. An outwardly protruding flange is provided on the outer side of the upper support body.

[0015] With the above settings, one end of the support column is limited by arranging one end of the support column in the third groove. At the same time, the contact area with the object to be jacked is increased through the outwardly protruding flange, increasing the support force for the object to be jacked.

[0016] Furthermore, an outwardly protruding lower flange is provided on the outer side of the support body.

[0017] With the above settings, by providing the lower flange, the contact surface between the support and the jacking mechanism is increased, thereby ensuring the connection reliability.

[0018] Furthermore, the diameter of the inner side wall of the first groove and the diameter of the inner side wall of the second groove are larger than the diameter of the outer side wall of the support rod.

[0019] With the above settings, when the diameters of the first groove and the second groove are slightly larger than the diameter of the support rod, the support rod is more likely to be axially aligned with the support and the adapter during the assembly process, thereby achieving rapid and precise installation and improving the assembly accuracy.

[0020] Further, the connecting hole, the fixing hole, and the fixing member are coaxially arranged, and the cross-section of the outer side wall of the fixing member is smaller than the cross-section of the inner side wall of the connecting hole.

[0021] With the above settings, it is convenient for the support column to pass through the connecting hole and be arranged in the first groove, and the coaxial arrangement enables the support column to be vertically fixed on the support. Description of the Drawings

Specific Embodiments

[0029] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0030] Embodiment 1.

[0031] As Figures 1-5 shown, a lifting tool for a slewing platform includes a support device. The support device includes a support 11, an upper support 12, a docking head 2, and a support rod 3. The two support rods 3 can be connected through the docking head 2. One end of the support rod 3 is detachably connected to the support 11, and the other end of the support rod 3 is detachably connected to the upper support 12. Moreover, the two support rods 3 can be spliced through the docking head 2, so that the height of the entire support assembly can be adjusted according to actual needs, increasing the applicability of the support assembly. The detachable connection between the support rod 3 and the support simplifies the installation and disassembly steps during use and saves time.

[0032] like Figure 1 and Figure 4 As shown, a connecting plate 31 is provided at the bottom of the support rod 3, and a connecting hole 311 is provided on the connecting plate 31. The connecting hole 311 is provided through the upper end of the fixing member.

[0033] There are many specifications of support columns: 100mm support rod 3, 200mm support rod 3, 300mm support rod 3, 400mm support rod 3, 500mm support rod 3, 1000 mm support rod 3. The use of support rods 3 of different specifications can reduce the customized cutting of support rods 3 due to the need for jacking height. During the jacking process, support rods 3 of different lengths are used to adapt to jacking heights of different heights. 1000mm support rod 3 can be used for higher jacking heights, and 100mm support rod 3 can be used for lower jacking heights. When the jacking height is greater than 1000mm, two or more support rods 3 can be connected through the joint 2 to meet the required jacking height.

[0034] The diameters of support rods 3 of different specifications are the same. Support rods 3 of the same diameter can distribute the load more evenly when subjected to force, and there is no need to worry about installation failure due to different sizes during assembly. Support rods 3 of the same diameter can be quickly docked using a unified docking joint 2, and there is no need to set different docking joints 2 for the support rods 3.

[0035] like Figures 1-2 As shown, first grooves 21 for accommodating one end of the support column are respectively provided at the upper and lower ends of the docking joint 2, and a support base plate 22 is provided between the bottoms of the two first grooves 21, and a first through hole 221 is provided on the support base plate 22. The setting of the first groove 21 helps the support rod 3 to better bear the force when connected to the docking joint 2, and realizes rapid positioning, facilitates the support rod 3 to be relative to the axis of the docking joint 2, and improves the stability and strength of the connection between the support rod 3 and the docking joint 2. The first through hole 221 and the first groove 21 are coaxially arranged, and the cross-sectional size of the connecting hole on the support column 3 is smaller than the cross-sectional size of the first through hole 221.

[0036] like Figure 3As shown, the support 11 includes a support body 110. A second groove 112 is provided on the support body 110. One end of the support column 3 is arranged in the second groove 112. A fixing hole 111 is provided on the bottom surface of the support body 110 and is arranged in the second groove 112. The fixing member 4 is fixedly connected with one end of the jacking mechanism 5 through the fixing hole 111. An outwardly protruding lower flange 1101 is provided on the outer side of the support body 110. In this embodiment, the fixing member 4 is a screw, and the fixing hole 11 is a threaded hole. The support is provided with a second groove 112, and a threaded hole is provided below the second groove 112. The support is provided with the second groove 112, which facilitates the docking with the support rod 3 on the support, reduces the docking time, and a through hole is provided in the second groove 112 of the support. The support can be fixedly connected with the equipment through the threaded hole 111, enhancing the stability of the support.

[0037] As Figure 1 shown, the upper support 12 includes an upper support body 121. A third groove 122 is provided on the upper support body 121. The end of the support column 3 away from the jacking mechanism is arranged in the third groove 122. An outwardly protruding flange 1210 is provided on the outer side of the upper support body 121. A fixing hole (not shown in the figure) for the fixing member to pass through can also be provided at the bottom of the upper support body 121. After the fixing member passes through the connection hole of the support column and the fixing hole, it is fixedly connected with the object to be supported.

[0038] The first groove 21, the second groove 112, the fixing hole 111, the connection hole, and the first through hole 221 are coaxially arranged. The cross-sectional area of the outer side wall of the fixing member 4 is smaller than the cross-sectional area of the inner side wall of the connection hole 311. The diameters of the first groove 21 and the second groove 112 are slightly larger than the diameter of the support rod 3. When the diameters of the first groove 21 and the second groove 112 are slightly larger than the diameter of the support rod 3, the support rod 3 is more likely to be axially aligned with the support 1 and the docking head 2 during the assembly process, thus achieving rapid and precise installation and improving the assembly accuracy.

[0039] The working principle of the present utility model: When the jack has jacked up the required equipment, the lower support 11 is fixedly connected with the bottom of the jacking mechanism 5 through the fixing hole 111. One end of the support rod 3 passes through the first through hole of the fixing member and extends into the second groove 112 of the lower support 11. The other end of the support rod 3 is connected to the first groove 21 on the lower side of the docking head 2. The first groove 21 on the upper side of the docking head 2 is connected to another support rod 3. The other end of the support rod 3 is connected to the upper support 12. At this time, there is a gap between the upper support 12 and the equipment to be jacked up. The jack slowly descends so that the upper support 12 contacts the equipment to be jacked up.

[0040] When using multiple supports and support rods 3 to support the equipment, since the sizes of the supports are the same, only the same support rods 3 need to be used to maintain the support heights of the multiple support rods 3. Moreover, due to the separate settings of the support rods 3, the docking heads 2, and the supports 1, they can be disassembled and replaced individually without replacing the entire structure as a whole.

[0041] Embodiment 2.

[0042] As Figure 6 shown, the difference between this embodiment and Embodiment 1 is only that: there is no need to set up a docking head, so the support rod corresponding to the required height is used and then connected through the support and the upper support. When the jacking height matches the height of the support rod 3, there is no need to use the docking head 2 for splicing, and one end of the support rod 3 can be connected to the lower support 11, and the other end of the support rod 3 can be connected to the upper support 12.
