Description

Technical Field

[0001] The utility model relates to the technical field of tower crane splicing, in particular to an inner jacking type standard section structure of a tower crane. Background Art

[0002] Tower crane is the most commonly used lifting equipment on construction sites. It is also called "tower crane". It is connected in sections, which are referred to as "standard sections". It is used to lift construction materials such as steel bars, wooden slats, concrete, steel pipes, etc. Tower crane is an indispensable equipment on construction sites.

[0003] However, traditional tower cranes will be lifted according to work requirements. Therefore, when lifting, the number of connecting bolts between the standard plates of the standard section structure largely determines the efficiency of the tower crane lifting. In traditional tower cranes, when lifting, eleven bolts are required to connect the standard plates in pairs, which is a large number. Therefore, a lot of time is required during the connection, which reduces work efficiency and is not conducive to practical applications. Utility Model Content

[0004] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide an inner jacking type standard section structure of a tower crane.

[0005] The technical solution of the utility model is as follows: an internal jacking type standard section structure of a tower crane, including a standard plate, wherein the standard plate is composed of a standard horizontal plate and four standard vertical plates, the four standard vertical plates are equidistantly fixedly connected to one side of the standard horizontal plate, wherein one end of the three standard vertical plates away from the standard horizontal plate is sequentially fixedly connected with a first splicing plate, a second splicing plate and a third splicing plate, a connecting plate is arranged between the first splicing plate, the second splicing plate and the third splicing plate, seven second connecting holes are opened on the other side of the standard horizontal plate, two first connecting holes are opened on the top of the first splicing plate, the second splicing plate and the third splicing plate, four steps are equidistantly arranged on the inner side of the standard horizontal plate, and four standard plates constitute a standard section.

[0006] A first inclined plate is fixedly connected between the third splicing plate and the first splicing plate and the standard transverse plate, and a second inclined plate is fixedly connected between the third splicing plate and the first splicing plate and the standard transverse plate and on one side of the first inclined plate.

[0007] As a preferred implementation, the second connection hole opened on one side of the standard transverse plate corresponds to the position of the first connection holes opened on the first splicing plate, the second splicing plate and the third splicing plate.

[0008] As a preferred implementation, the four standard plates form a rectangular parallelepiped structure, and steps are equidistantly arranged on the inner sides of the two diagonal standard horizontal plates.

[0009] As a preferred implementation, the first inclined plate, the second inclined plate, the standard horizontal plate, the standard vertical plate and the connecting plate are all arranged in an L-shaped structure.

[0010] As a preferred implementation, the first inclined plate, the standard horizontal plate and the standard vertical plate form a triangular structure, and the second inclined plate, the standard horizontal plate and the standard vertical plate form a triangular structure.

[0011] As a preferred implementation, the first splicing plate, the second splicing plate and the third splicing plate are mounted on the side wall of the standard cross plate by means of fixing bolts.

[0012] As a preferred implementation, the fixing bolts inside the first splicing plate, the second splicing plate and the third splicing plate completely pass through the first connecting hole and the second connecting hole.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. Four standard pieces are erected to form a rectangular structure, and then seven bolts are passed through the first connection hole and the second connection hole of two adjacent standard pieces to fix the standard pieces on both sides. This solution reduces the number of connecting bolts to seven, which is eleven compared to the traditional connection of different standard pieces. The number of bolts is greatly reduced, and higher strength bolts are used in place of the connecting bolts, which reduces the damage rate during installation, thereby ensuring that the overall connection strength of the standard section remains unchanged, improving the efficiency of tower crane lifting, and making it more conducive to practical application;

[0015] 2. When lifting, the number of steps is reduced from five to four, and the distance between each layer is lengthened accordingly. The lifting cylinder is replaced with a model with a longer stroke to ensure sufficient stroke for jacking. When the standard section has five steps, the cylinder needs to be retracted and extended five times to complete the lifting work of a standard section height. After reducing the number of steps to four, the cylinder only needs to be retracted and extended four times to complete the lifting work of a standard section height, which improves the speed of jacking and adding sections and enhances the practicality of the device.

[0026] Example 1

[0027] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: including a standard sheet 1, the standard sheet 1 is composed of a standard horizontal plate 101 and four standard vertical plates 102, the four standard vertical plates 102 are equidistantly fixedly connected to one side of the standard horizontal plate 101, wherein the ends of the three standard vertical plates 102 away from the standard horizontal plate 101 are sequentially fixedly connected with the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6, and a connecting plate 10 is arranged between the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6, and the other end of the standard horizontal plate 101 is fixedly connected with the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6. Seven second connecting holes 9 are provided on one side, two first connecting holes 8 are provided on the top of the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6, four steps 7 are equidistantly arranged on the inner side of the standard cross plate 101, four standard plates 1 form a standard section, the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6 are installed on the side wall of the standard cross plate 101 by fixing bolts, and the fixing bolts inside the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6 completely pass through the first connecting holes 8 and the second connecting holes 9.

[0028] In this embodiment, four standard plates 1 are erected to form a rectangular structure, and then seven bolts are passed through the first connecting hole 8 and the second connecting hole 9 of two adjacent standard plates 1 to fix the standard plates 1 on both sides. This solution reduces the number of connecting bolts to seven, which is eleven compared to the traditional method of connecting different standard plates 1, greatly reducing the number of bolts. In addition, when the connecting bolts are reduced, higher strength bolts are used instead, and the damage rate during installation is lower, thereby ensuring that the overall connection strength of the standard section remains unchanged, improving the efficiency of tower crane jacking, and making it more conducive to practical application; at the same time, the steps 7 on the inner side of the standard cross plate 101 are set to four, so that the spacing between each step 7 is lengthened accordingly, so that the cylinder only needs to retract and extend four times to complete the jacking work of a standard section height, thereby improving the speed of jacking and adding sections and enhancing the practicality of the device.

[0029] Example 2

[0030] like Figure 1-Figure 5 As shown, a first inclined plate 2 is fixedly connected between the third splicing plate 6 and the first splicing plate 4 and the standard transverse plate 101, and a second inclined plate 3 is fixedly connected between the third splicing plate 6 and the first splicing plate 4 and the standard transverse plate 101 and on one side of the first inclined plate 2. By arranging the first inclined plate 2 and the second inclined plate 3, the stability between the standard transverse plate 101 and the splicing plates is enhanced.

[0031] Among them, the second connecting hole 9 opened on one side of the standard cross plate 101 corresponds to the position of the first connecting hole 8 opened on the first splicing plate 4, the second splicing plate 5 and the third splicing plate 6. By setting the first connecting holes 8 and the second connecting holes 9 corresponding to each other, when splicing the standard sections, the bolts can pass through the first connecting holes 8 and the second connecting holes 9, thereby fixing the two standard plates 1.

[0032] The four standard plates 1 form a rectangular parallelepiped structure, and steps 7 are equidistantly arranged on the inner sides of two diagonal standard horizontal plates 101 .

[0033] Among them, the first inclined plate 2, the second inclined plate 3, the standard horizontal plate 101, the standard vertical plate 102 and the connecting plate 10 are all arranged in an L-shaped structure, and the stability of the first inclined plate 2, the second inclined plate 3, the standard horizontal plate 101, the standard vertical plate 102 and the connecting plate 10 is enhanced through the L-shaped structure.

[0034] Among them, the first inclined plate 2, the standard horizontal plate 101 and the standard vertical plate 102 form a triangular structure, and the second inclined plate 3, the standard horizontal plate 101 and the standard vertical plate 102 form a triangular structure. By setting up the triangular structure, the stability of the standard plate 1 is enhanced by utilizing the stable characteristics of the triangle.

[0035] Working principle: four standard plates 1 are erected to form a rectangular structure, and then seven bolts are passed through the first connecting hole 8 and the second connecting hole 9 of two adjacent standard plates 1 to fix the standard plates 1 on both sides. This solution reduces the number of connecting bolts to seven. Compared with the traditional method of connecting different standard plates 1 with eleven bolts, the number of bolts is greatly reduced. In addition, when the connecting bolts are reduced, higher strength bolts are used instead, and the damage rate during installation is lower, thereby ensuring that the overall connection strength of the standard section remains unchanged, improving the efficiency of tower crane jacking, and making it more conducive to practical application; at the same time, the steps 7 on the inner side of the standard cross plate 101 are set to four, so that the spacing between each step 7 is lengthened accordingly, so that the cylinder only needs to retract and extend four times to complete the jacking work of a standard section height, thereby improving the speed of jacking and adding sections and enhancing the practicality of the device.

[0036] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
