Description

TECHNICAL FIELD

[0001] The utility model relates to the field of reversing, especially a reversing device and a building machine. BACKGROUND

[0002] In the jacking system of the building machine, the upper reversing box connected with the oil cylinder completes the jacking of the column through the extension and retraction of the oil cylinder. When the oil cylinder extends, the clamping plate of the upper reversing box clamps into the clamping groove of the supporting column to jacks up the supporting column. When the oil cylinder retracts, the clamping plate slides out of the clamping groove of the column at the previous level and enters the clamping groove at the next level to enter the next jacking cycle. The lower reversing box connected with the oil cylinder support plays a role in preventing the column from falling when jacking the column. When the oil cylinder support is lifted, the clamping plate of the lower reversing box slides out of the clamping groove of the column at the previous level and enters the clamping groove at the previous level to support the oil cylinder support, and the oil cylinder extends to enter the next oil cylinder support lifting cycle. By pulling or pressing the clamping plate handle of the upper and lower reversing boxes into the clamping groove of the supporting guide column, the reversing action is completed. Before the clamping plate is completely positioned, the handle must be continuously positioned to prevent the clamping plate from not clamping in place during jacking, causing the column to be jacked, or the clamping plate from clamping the guide column during descent. However, the existing reversing box clamping plate cannot automatically adjust the angle according to the reversing needs to smoothly clamp into or slide out of the guide column clamping groove to complete the reversing action, which poses a great safety hazard.

[0003] In addition, the existing reversing box is provided with only one clamping plate, and the single clamping plate may not be able to smoothly clamp into the column clamping groove. Secondly, the single clamping plate has insufficient and unstable support for the column or the oil cylinder support, and thus has weak anti-falling ability for the column or the oil cylinder support. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a reversing device that adjusts the reversing angle according to the reversing needs and is safe and reliable.

[0005] The technical problem to be solved by the utility model is also to provide a building machine provided with the reversing device.

[0006] To solve the above technical problems, the utility model provides a reversing device, which comprises a reversing body and a reversing mechanism, the reversing mechanism comprises a reversing assembly and a positioning mechanism, the reversing assembly and the reversing body are movably connected, and the positioning mechanism is used for adjusting the rotation angle of the reversing assembly and positioning the reversing assembly.

[0007] The positioning mechanism comprises a positioning body, one end of the positioning body is movably connected with the reversing body, the other end is connected with the reversing assembly, and the positioning body is telescopic to adjust the rotation angle of the reversing assembly.

[0008] As an improvement of the above scheme, the positioning body is an air spring.

[0009] As the improvement of the above scheme, the number of the positioning mechanisms is at least two, which are respectively arranged on two sides of the reversing assembly.

[0010] As the improvement of the above scheme, the number of the reversing assemblies is at least two, and each of the reversing assemblies is connected with the positioning mechanism.

[0011] As the improvement of the above scheme, the reversing assembly comprises a reversing plate and a reversing handle, the reversing plate and the reversing handle are fixedly connected, and the reversing plate and the reversing body are rotatably connected.

[0012] The reversing handle is connected with the positioning mechanism through a connecting rod.

[0013] As the improvement of the above scheme, the reversing mechanism comprises a connecting assembly arranged on the reversing body, the connecting assembly comprises a rotating shaft and a positioning plate, the positioning plate is embedded on the rotating shaft, so that the rotating shaft and the reversing body are fixedly connected.

[0014] The reversing plate is sleeved on the rotating shaft, and the reversing plate can rotate around the rotating shaft.

[0015] One end of the positioning body is rotatably connected with the rotating shaft, and the other end is connected with the connecting rod.

[0016] As the improvement of the above scheme, the reversing body is provided with a plurality of guide grooves, the reversing assembly is arranged in the guide groove, and the reversing assembly and the guide groove are arranged in one-to-one correspondence.

[0017] The guide groove is provided with a limiting block, and the reversing plate can interfere with the limiting block to limit the reversing plate.

[0022] This utility model's reversing device is equipped with a positioning mechanism. The positioning mechanism is used to adjust the rotation angle of the reversing component and position the reversing component. The positioning mechanism includes a positioning body, one end of which is movably connected to the reversing body, and the other end is connected to the reversing component. By extending and retracting the positioning body, the rotation angle of the reversing component is adjusted, so that the reversing component can smoothly engage with the guide column slot during lifting or smoothly slide out of the guide column slot during lowering. That is, the rotation angle of the reversing component is adjusted according to the different opening and closing angle requirements of the reversing component, ensuring that the reversing component is always in the correct position. This reduces the risk of the support column falling during lifting or lowering due to loose positioning of the reversing component, thereby ensuring the reliability and safety of the reversing device's positioning.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0027] See Figures 1-3 This utility model discloses a reversing device, including a reversing body 1 and a reversing mechanism. The reversing mechanism includes a reversing component and a positioning mechanism. The reversing component and the reversing body 1 are movably connected. The positioning mechanism is used to adjust the rotation angle of the reversing component and position the reversing component.

[0028] The positioning mechanism includes a positioning body 5, one end of which is movably connected to the reversing body 1 and the other end is connected to the reversing assembly. The positioning body 5 extends and retracts to adjust the rotation angle of the reversing assembly.

[0029] This utility model's reversing device is equipped with a positioning mechanism. The positioning mechanism is used to adjust the rotation angle of the reversing component and position the reversing component. The positioning mechanism includes a positioning body, one end of which is movably connected to the reversing body, and the other end is connected to the reversing component. By extending and retracting the positioning body, the rotation angle of the reversing component is adjusted, so that the reversing component can smoothly engage with the guide column slot during lifting or smoothly slide out of the guide column slot during lowering. That is, the rotation angle of the reversing component is adjusted according to the different opening and closing angle requirements of the reversing component, ensuring that the reversing component is always in the correct position. This reduces the risk of the support column falling during lifting or lowering due to loose positioning of the reversing component, thereby ensuring the reliability and safety of the reversing device's positioning.

[0030] Preferably, the positioning body 5 is an air spring. An air spring is a spring that utilizes the elasticity of air by filling a retractable sealed container with compressed air. Existing technology can be used for air springs, and they will not be described in detail here. This invention uses an air spring to adjust the rotation angle of the reversing assembly according to different opening and closing angle requirements, i.e., automatically adjusting the opening and closing angle of the reversing assembly to ensure that the reversing assembly is always in the correct position, reducing the risk of the support column falling during lifting or lowering due to loose positioning of the reversing assembly.

[0031] Preferably, there are at least two positioning mechanisms, each located on one side of the reversing assembly. The two positioning mechanisms ensure balanced forces on both sides of the reversing assembly, preventing jamming and facilitating smooth angle adjustment.

[0032] Preferably, the number of reversing components is at least two sets, and each reversing component is connected to the positioning mechanism. The use of two or more reversing components reduces the risk of a single reversing component failing to smoothly engage with the column slot, and strengthens the support force and stability of the column or cylinder bracket, thus enhancing its anti-fall capability. It should be noted that all reversing components should move synchronously.

[0033] Specifically, such as Figures 1-2 As shown, the reversing assembly includes a reversing plate 2 and a reversing handle 3. The reversing plate 2 and the reversing handle 3 are fixedly connected, and the reversing plate 2 and the reversing body 1 are rotatably connected. The reversing handle 3 is connected to a positioning mechanism via a connecting rod 4. This invention utilizes air springs to automatically adjust the angle of the reversing plate according to the reversing requirements, allowing the reversing plate to smoothly engage or disengage from the guide post slot to complete the reversing action. The reversing plate, reversing handle, connecting rod, and air spring are connected sequentially. The reversing handles of multiple reversing assemblies are all connected to the connecting rod to ensure that multiple reversing plates move synchronously. More specifically, the air springs synchronously adjust multiple reversing plates via the connecting rod. Two air springs are respectively located on both sides of multiple reversing plates, such as... Figures 1-2The positioning body 5 is rotatably connected to the rotating shaft 6 at one end and connected to the connecting rod 4 at the other end. The air spring is extended and retracted to drive the connecting rod to rotate the reversing plate. Preferably, the other end of the positioning body 5 is rotatably connected to the connecting rod 4.

[0034] More preferably, as shown in Figure 1 The reversing mechanism includes a connecting assembly mounted on the reversing body 1, which includes a rotating shaft 6 and a positioning plate 7 embedded on the rotating shaft 6 to fixedly connect the rotating shaft 6 and the reversing body 1. The reversing plate 2 is sleeved outside the rotating shaft 6 and can rotate around the rotating shaft 6.

[0035] The positioning plate is fixedly connected to the reversing body, and the positioning plate is embedded on the rotating shaft, so that the rotating shaft does not rotate or separate from the reversing body, thereby ensuring the reliability of the connection between the reversing plate and the reversing body. The reversing plate rotates around the rotating shaft to complete the reversing action, and the air spring drives the connecting rod to drive the reversing handle to adjust the angle of rotation of the reversing plate.

[0036] More preferably, as shown in Figures 1-2 The reversing body 1 is provided with a plurality of guide grooves 11, and the reversing assembly is arranged in the guide groove 11. That is to say, each reversing assembly is arranged in the corresponding guide groove, so that the adjacent reversing plates do not interfere with each other and do not affect each other. The guide groove guides the rotation of the reversing plate to avoid deviation, jamming and other problems, and ensures that each reversing plate can be smoothly opened and closed. It should be noted that a plurality of reversing assemblies are arranged side by side, and the adjacent two reversing assemblies are separated by a partition. The rotating shaft 6 is arranged in the plurality of guide grooves 11, and the plurality of reversing plates 2 are sleeved on the same rotating shaft 6, which has a simple structure.

[0037] Preferably, as shown in Figures 1-2 The guide groove 11 is provided with a limiting block 12, and the reversing plate 2 can interfere with the limiting block 12 to limit the reversing plate 2. The limiting block limits the rotation range of the reversing plate to avoid the reversing plate being jammed on the reversing body, and assists the reversing plate to be smoothly clamped into or slid out of the guide column clamping groove, further ensuring the reliability of the reversing plate clamping.

[0038] Preferably, as shown in Figures 1-3As shown, the positioning mechanism further comprises a telescopic rod 8, one end of which is rotationally connected with the rotating shaft 6 and the other end is telescopically connected with the positioning body 5. The telescopic rod is telescopically extended or retracted under the action of the positioning body to transmit the air spring force. Specifically, the different opening and closing angle adjustment of the reversing plate is realized by adjusting the pressure of the air spring, i.e. the elastic force parameter. For example, the air spring is filled with compressed air or the compressed air is removed to drive the telescopic rod to extend or retract, so as to drive the reversing plate to rotate to a suitable angle, and the reversing plate is smoothly clamped into or slid out of the guide column clamping groove. When the air filling or air removal of the air spring is stopped, i.e. the telescopic rod stops extending or retracting, the reversing assembly can be positioned at a certain opening and closing angle to realize the positioning of the reversing plate, ensure that the reversing plate is in the correct position, and accurately clamp into or slide out of the guide column clamping groove to smoothly and accurately complete the reversing action.

[0039] More preferably, as shown in the drawings, Figure 3 As shown, the telescopic rod 8 is rotationally connected with the rotating shaft 6 through a first connecting head 9, and the positioning body 5 is connected with the connecting rod 4 through a second connecting head 10. One end of the telescopic rod 8 is provided with the first connecting head 9, and the first connecting head 9 is sleeved on the rotating shaft 6 through a positioning bolt, so that the telescopic rod can rotate around the rotating shaft. When the air spring drives the telescopic rod to extend or retract, the telescopic rod can rotate around the rotating shaft, and at the same time drives the connecting rod connected with the air spring to move, and the connecting rod drives the reversing assembly to rotate the reversing plate around the rotating shaft synchronously, so as to realize the opening and closing angle adjustment of the reversing plate. The second connecting head is fixed on the positioning body and is sleeved on the connecting rod.

[0040] The first connecting head and the second connecting head are provided to ensure that the telescopic rod and the positioning body are respectively connected with the rotating shaft and the connecting rod, so that the air spring force can be effectively transmitted, the opening and closing angle of the reversing plate can be accurately adjusted, the reversing assembly can always be in the correct position, the risk of the supporting column falling during the jacking or lowering process caused by the loosening of the positioning of the reversing assembly is reduced, and the reliability of the clamping of the reversing device is ensured.

[0041] Correspondingly, the utility model discloses a building machine, the building machine is equipped with above-mentioned reversing device. The specific structure of the reversing device is as described above, and will not be repeated here. The connection of the reversing device and the oil cylinder and other equipment of the building machine can adopt the prior art structure, and will not be introduced in detail here.

[0042] In summary, the utility model provides a reversing device and a building machine provided with the reversing device, which adjusts the reversing angle according to the reversing requirement, and is safe and reliable.

[0043] The above is the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, some improvements and refinements can be made without departing from the principles of the utility model, and these improvements and refinements are also regarded as the protection scope of the utility model.
