Description

Technical Field

[0001] The utility model relates to the field of reversing, in particular to a reversing device and a building construction machine. Background Art

[0002] In the building construction machine's lifting system, the upper reversing box connected to the oil cylinder completes the lifting of the column through the extension and retraction of the oil cylinder. When the oil cylinder extends, the card plate of the upper reversing box is inserted into the card slot of the supporting column, lifting the supporting column upward; when the oil cylinder retracts, the card plate slides out of the card slot of the column at the previous level and enters the card slot of the next level, entering the next jacking cycle. The lower reversing box connected to the oil cylinder bracket prevents the column from falling when lifting. When the oil cylinder bracket is lifted, the card plate of the lower reversing box slides out of the card slot of the column at the next level and enters the card slot of the previous level, supporting the oil cylinder bracket, and the oil cylinder extends, entering the next oil cylinder bracket lifting cycle.

[0003] However, the existing upper and lower reversing boxes are only equipped with one card plate, and there is a risk that the single card plate will not be able to be smoothly inserted into the column slot. Secondly, the support force of the single card plate on the column or cylinder bracket is insufficient and the support is unstable, so the anti-fall ability of the column or cylinder bracket is weak. In addition, the reset spring is not equipped with any positioning structure. The card plate and the reversing box are directly connected to the two ends of the spring. When the spring is extended and retracted, the spring is prone to swinging around, resulting in inaccurate and unreliable positioning of the card plate, and it is easy to be insufficiently positioned or even reversely positioned, affecting the normal operation of the building construction machine and low safety.

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0029] See also Figure 1-6 The utility model discloses a reversing device, including an upper reversing mechanism 10 and a lower reversing mechanism 20.

[0030] The upper reversing mechanism 10 and the lower reversing mechanism 20 have the same structure; the upper reversing mechanism 10 and the lower reversing mechanism 20 both include a reversing body 1, a reset mechanism and at least two reversing plates 2, a reversing cavity 11 is provided in the reversing body 1, the reversing plate 2 is installed in the reversing cavity 11 and can extend out of the reversing cavity 11, and the reversing plate 2 and the reversing body 1 are movably connected.

[0031] The reset mechanism includes an elastic component 3 , one end of which is connected to the reversing body 1 , and the other end of which is connected to the reversing plate 2 , so that the reversing plate 2 moves synchronously.

[0032] The reversing device of this utility model utilizes at least two reversing plates, which improves the reliability of the connection between the reversing plates and the column, reducing the risk of the reversing plates failing to fit into the column slots. This also enhances the supporting force on the column or cylinder bracket, making the supporting force more evenly distributed. This reduces the risk of the column or cylinder bracket falling during jacking or lifting, improving the anti-fall capability. Furthermore, the provision of a reset mechanism ensures the synchronous movement of the multiple reversing plates, further improving the reliability of the connection, enhancing the supporting force, and improving the anti-fall capability.

[0033] Preferably, the elastic component 3 is a spring, but not limited thereto.

[0034] Preferably, if Figure 1-6 As shown, the reset mechanism also includes a connecting rod 4 and a connecting bar 5. The reversing plate 2 is connected to the connecting rod 4 via the connecting bar 5, and the other end of the elastic component 3 is connected to the connecting rod 4. Specifically, one end of the connecting bar 4 is connected to the reversing plate 2, and the other end is connected to the connecting rod 4. The connecting bars 5 are arranged in a one-to-one correspondence with the reversing plates 2. When the elastic component contracts or expands, it simultaneously drives multiple connecting bars through the connecting rod, thereby simultaneously driving the movement of multiple reversing plates, ensuring the synchronous movement of multiple reversing plates, further improving the reliability of the connection, enhancing the supporting force, and improving the anti-fall capability.

[0035] Among them, Figure 1-5 As shown, a partition 6 is provided in the reversing cavity 11 and positioned between two adjacent reversing plates 2. One end of the elastic member 3 is connected to the partition 6. The provision of the partition not only separates the two reversing plates and prevents them from moving around, but also enables the elastic member to be positioned between the two reversing plates, ensuring a stable force on the reversing plates and smoother movement of the reversing plates, making them less susceptible to jamming.

[0036] Preferably, if Figure 1-5As shown, the reset mechanism comprises a positioning assembly, the positioning assembly comprises a first sleeve 7 and a second sleeve 8, the second sleeve 8 is sleeved outside the first sleeve 7 and can move back and forth along the axial direction of the first sleeve 7; the first sleeve 7 is connected with the connecting rod 4, and the second sleeve 8 is connected with the partition plate 6; the elastic component 3 is arranged in the first sleeve 7, and the two ends of the elastic component 3 are connected with the first sleeve 7 and the second sleeve 8 respectively. When the elastic component is stretched and contracted, the first sleeve and the second sleeve move away from each other or move towards each other. Since the second sleeve is sleeved outside the first sleeve, the first sleeve and the second sleeve move back and forth along the predetermined direction, which limits the stretching direction of the elastic component, avoids the spring swinging around, ensures the accurate and reliable positioning of the reversing plate, makes the reversing plate fully clamped on the clamping groove of the stand column, avoids reverse clamping, ensures the normal operation of the building machine, is high in safety, and thus ensures the accuracy and reliability of the positioning of the reversing device. Specifically, the first sleeve 7 is rotationally connected with the connecting rod 4, and the second sleeve 8 is hingedly connected with the partition plate 6.

[0037] Preferably, as shown in Figure 1-5 , the partition plate 6 is provided with a notch 61, and the positioning assembly is arranged in the notch 61. The arrangement of the notch makes the positioning assembly arranged in the notch, thereby saving space.

[0038] More preferably, as shown in Figure 3 , the notch 61 is in the shape of a V. The connection between the second sleeve 8 and the partition plate 6 is arranged at the bottom of the V-shaped notch 61, as shown in Figure 2-4 . When the elastic component is stretched and contracted, the positioning assembly may be in contact with the side wall of the notch, thereby limiting the movement of the reset mechanism, i.e. limiting the movement range of the reset mechanism, and further ensuring the accuracy and reliability of the positioning of the reversing plate.

[0039] Further, as shown in Figure 2-4 , 6, the utility model also includes a connecting assembly arranged on the reversing body 1, the connecting assembly comprises a pin shaft 14 and a fixed block 15, the pin shaft 14 is arranged on the reversing body 1 and arranged in the reversing cavity 11, the reversing plate 2 is rotationally connected with the pin shaft 14, and the fixed block 15 is fixedly installed on the reversing body 1 and clamped on the pin shaft 14. The reversing plate is rotationally connected with the reversing body through the pin shaft. The fixed block is fixed on the outer side wall of the reversing body through screws and the like fasteners and is clamped on the pin shaft, which can prevent the pin shaft from shifting and ensure the stability and reliability of the rotation of the reversing plate.

[0040] Preferably, as shown in Figure 1-3 , 5, a limiting block 13 is arranged in the reversing cavity 11, the limiting block 13 can be in contact with the reversing plate 2 to limit the angle and range of rotation of the reversing plate 2, thereby ensuring the accuracy and reliability of the positioning of the reversing plate.

[0041] Still further, as shown in Figure 2-3 As shown in Figures 6 and 7, the reversing body 1 is provided with a guide groove 12 for guiding the movement of the upper reversing mechanism 10 or the lower reversing mechanism 20. The pillar is embedded in the guide groove, which ensures that the reversing device and the pillar are securely connected, ensuring that it can move along the pillar. It also further improves the reliability of the connection between the reversing plate and the pillar and reduces the risk of the reversing plate not being able to be inserted into the pillar slot.

[0042] Preferably, if Figure 1-4 As shown, the present invention further includes a guide assembly disposed on the reversing body 1. The guide assembly comprises a guide bar 16 and a sleeve 17. The sleeve 17 is mounted outside the guide bar 16 and connected to the guide bar 16. The guide bar 16 and the sleeve 17 form a guide groove 12. There are at least two guide bars, which are arranged along the extension direction of the column. The sleeve is mounted outside the guide bar and connected by the sleeve. The guide bar and the sleeve form a guide groove. That is, the guide assembly is mounted outside the column, and the reversing body is connected to the column via the guide assembly, ensuring the reliability and stability of the connection between the reversing device and the column.

[0043] Accordingly, see Figure 1-6 The present invention also discloses a building construction machine comprising a telescopic device (not shown) and the aforementioned reversing device. The upper reversing mechanism 10 and the lower reversing mechanism 20 are respectively disposed at the upper and lower ends of the telescopic device. The specific structure of the reversing device is as described above and will not be further elaborated here. The telescopic device is preferably a hydraulic cylinder.

[0044] When the telescopic device extends, the reversing plate 2 of the upper reversing mechanism 10 engages with the top of the slot of the column due to its engagement with the slot. At the same time, the outer bottom of the reversing plate 2 engages the limit block 13, preventing the reversing plate 2 from rotating. As a result, the column is lifted by the upper reversing mechanism 10. At this time, the upward movement of the column acts on the reversing plate 2 of the lower reversing mechanism 20, causing the reversing plate 2 to rotate, causing it to engage the limit block 13 above and outside it, limiting its rotation angle. At the same time, the reversing plate 2 is reset by the action of the elastic member. It should be noted that during this process, the two reversing plates of the upper reversing mechanism rotate synchronously, and the two reversing plates of the lower reversing mechanism rotate synchronously, which not only ensures the reliability of the connection between the reversing plate and the column, reduces the risk of the reversing plate failing to fit into the column slot, but also enhances the supporting force on the column or cylinder bracket, making the supporting force distribution more balanced; reduces the risk of the column or cylinder bracket falling during jacking or lifting, and improves the anti-fall capability.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
