However, since the columns are a pair and are distributed on both sides of the base, the two need to be installed symmetrically. If welding is used, the installation position needs to be repeatedly surveyed on both sides of the chassis, and after welding, it is still impossible to ensure that the two columns have a high installation accuracy, and it is quite troublesome to adjust the position after welding; in addition, if bolting is used, the front and rear angles of the columns need to be repeatedly adjusted during the installation process, and it is basically difficult to ensure that the columns on both sides maintain good symmetry.

[0003] Based on this, it is necessary to develop a new column installation mechanism to ensure that the two columns can be installed with high precision. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example 1

[0025] like Figure 1 , 2 As shown in Figures 3, the column installation mechanism of this embodiment includes a base 1 and two columns 2. The base 1 is horizontally arranged, and column connecting parts 11 are symmetrically arranged on both sides thereof. The two columns 2 are respectively vertically arranged and symmetrically distributed on both sides of the base 1. The lower ends of the two columns 2 are respectively and one-to-one correspondingly engaged and positioned with the ends of the two column connecting parts 11, and are connected and fixed by high-strength bolts 3.

[0026] In this embodiment, column connecting parts 11 are symmetrically arranged on both sides of the base 1, and a pair of columns 2 are arranged on both sides of the base 1. The columns 2 are arranged vertically, and the ends of the column connecting parts 11 on both sides away from the base 1 are assembled with the lower ends of the columns 2 on the corresponding sides in a chimeric positioning manner, and the two realize high-strength positioning installation. After assembly, the columns 2 will not be displaced or shaken, and are then connected and fixed with high-strength bolts 3, so that high-precision and high-strength assembly is achieved between the columns 2 and the column connecting parts 11. This improves the traditional assembly between the column and the base of the tractor by welding or bolt connection, without a positioning structure design, resulting in the need for repeated adjustment of the position of the column 2 after or during installation, which is more troublesome to operate and there is no way to ensure the accuracy after installation.

[0027] As a preferred embodiment, the two column connecting parts 11 are respectively perpendicular to the middle parts of both sides of the base 1, and one end of the two column connecting parts 11 is integrally provided with a connecting ear seat 111, the connecting ear seat 111 is fitted with the corresponding side of the base 1, and is connected and fixed to the connecting ear seat 111 by bolts passing through it, and the other end of the column connecting part 11 is embedded and positioned with the column 2.

[0028] In the above embodiment, one end of the two column connecting parts 11 is fitted with the corresponding side of the base 1 through the connecting ear seat 111, and is fixed by bolts passing through the connecting ear seat 111 and the corresponding side plate of the base 1. Generally, a first bolt hole is opened at the position corresponding to the connecting ear seat 111 on both sides of the base 1, and a second bolt hole is opened on the connecting ear seat 111. After the first bolt hole and the second bolt hole are aligned, bolts are installed to fix it.

[0029] As a preferred embodiment, the connecting ear seats 111 are respectively provided on both sides of one end of the column connecting portion 11 .

[0030] In the above embodiment, one end of the column connecting portion 11 is connected and fixed to the side end of the base 1 through two connecting ear seats 111 that are horizontally spaced apart, so that the assembly of the column connecting portion 11 and the base 1 is relatively firm.

[0031] As a preferred embodiment, a positioning groove 112 is provided at the other end of the column connecting part 11, and a positioning protrusion 21 adapted to the positioning groove 112 is provided on one side of the lower end of the column 2. The positioning protrusion 21 is embedded in the positioning groove 112 and is connected and fixed to the other end of the column connecting part 11 by a high-strength bolt 3 passing through it.

[0032] In the above-mentioned implementation scheme, the column 2 is vertical during the installation process, and the positioning protrusion 21 on one side of the lower end thereof is directly embedded in the positioning groove 112 at the other end of the column connecting portion 11. A first through hole corresponding to the high-strength bolt is penetrated at the bottom of the positioning groove 112, and a second through hole is penetrated on the positioning protrusion 21. After the positioning protrusion 21 is embedded in the positioning groove 112, the first through hole and the second through hole are aligned, and then the high-strength bolt 3 is passed through and locked with a nut. Since the positioning protrusion 21 is embedded in the positioning groove 112, the subsequent installation process of the column will not cause shaking and displacement forward and backward or left and right, and the assembly accuracy is relatively high.

[0033] As a preferred embodiment, the positioning protrusion 21 is a vertically extending rectangular block, and the corresponding positioning groove 112 is a rectangular groove vertically penetrating the middle area of ​​the other end of the column connecting portion 11 .

[0034] In the above implementation scheme, the positioning protrusion 21 is a rectangular block, and the positioning groove 112 is a rectangular groove. During installation, the positioning protrusion 21 at the lower end of the column 2 is aligned with the positioning groove 112 and embedded (inserted) into the positioning groove 112 from top to bottom. After the two are engaged, the column 2 will not shake or shift relative to the positioning groove 112. After being fixed with high-strength bolts 3 that penetrate the positioning protrusion 21 and the positioning groove 112, high-precision and high-strength assembly of the column 2 can be ensured.

[0035] In this embodiment, the high-strength bolts 3 are provided in plurality and are spaced apart vertically. The plurality of high-strength bolts 3 ensures that the column 2 is securely installed.

[0036] As a preferred embodiment, a protruding reinforcement portion 22 is provided at the other side of the lower end of the column 2 corresponding to the positioning protrusion 21 , and the high-strength bolt 3 passes through the reinforcement portion 22 and the positioning protrusion 21 .

[0037] In the above implementation scheme, since a through hole for the high-strength bolt 3 to pass through is to be opened through the positioning protrusion 21, a reinforcing portion 22 is also provided on the other side of the column 2 to enhance the structural strength of the through hole to ensure that there is no risk of breakage, deformation, etc. around the through hole during long-term use.

[0038] In this embodiment, a positioning groove 23 is provided at the upper end of the column 2. The positioning groove 23 is suitable for installing the corresponding components of the front loading.

[0039] As a preferred embodiment, a plurality of recessed surfaces are provided at intervals up and down on one side of the column 2 , and structural reinforcement ribs 24 are formed between the recessed surfaces.

[0040] In the above implementation scheme, the design of the recessed surface reduces the structural strength of the column 2 to a certain extent, and the structural reinforcement ribs 24 formed between the recessed surfaces further enhance the structural strength. Therefore, on the whole, while reducing the weight of the column 2, its structural strength can be ensured not to decrease.
