Description

Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a steel pipe supporting structure. Background Art

[0002] The air intake system of a tractor generally includes an air pre-filter and an air filter. After being pre-filtered by the air pre-filter, the air enters the air filter for purification, and the purified air enters the engine for use by the engine. In order to ensure that the air pre-filter is in a good working environment, the air pre-filter is usually placed at the highest point of the tractor and connected to the air filter through a steel pipe fixed to the side of the cab.

[0003] At present, an auxiliary tie rod is usually used to fix the steel pipe to the side of the cab. However, due to the independent swaying characteristics of the cab, coupled with the up and down vibrations generated when the engine is working, and the auxiliary tie rod is a rigid connector, it is very easy for the tractor's swaying and vibration to be transmitted to the steel pipe and the air pre-filter, causing the steel pipe and the air pre-filter to suffer varying degrees of vibration damage, seriously affecting their service life. In particular, with the increase in working hours, the auxiliary tie rod generally becomes looser and finally the support fails. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] like Figure 1As shown, the air intake system of the tractor generally includes an air pre-filter a and an air filter (not shown in the figure). After being pre-filtered by the air pre-filter a, the air enters the air filter for purification, and the purified air enters the engine (not shown in the figure) for use by the engine. In order to ensure that the air pre-filter a is in a good working environment, the air pre-filter a is usually placed at the highest point of the tractor and connected to the air filter through a steel pipe c fixed to the side of the cab b.

[0023] The present embodiment discloses a steel pipe support structure d, through which a steel pipe c is fixed to the side of a cab b. The steel pipe support structure d includes a fixed connector 1, a shock-absorbing connector 2 and a pipe clamp 3. The shock-absorbing connector 2 includes a first connecting plate 21 and a second connecting plate 22 that are perpendicular to each other, and an intermediate connecting plate 23 connected between the first connecting plate 21 and the second connecting plate 22. The first connecting plate 21 is connected to the fixed connector 1, and a first shock absorber 4 for shock absorption in the vertical direction is arranged therebetween; the second connecting plate 22 is connected to the pipe clamp 3, and a second shock absorber 5 for shock absorption in the horizontal direction is arranged therebetween.

[0024] The steel pipe support structure d in this embodiment has a first shock absorber 4 for shock absorption in the vertical direction and a second shock absorber 5 for shock absorption in the horizontal direction. Therefore, it can effectively prevent external impacts in the vertical and horizontal directions from directly acting on the steel pipe c, thereby achieving stable support for the steel pipe c, reducing the vibration impact on the steel pipe c and the air pre-filter a, reducing the noise caused by vibration, and extending the service life of the steel pipe c and the air pre-filter a.

[0025] In this embodiment, the first shock absorber 4 and the second shock absorber 5 both include an elastic member 41 and a bolt (not shown in the figure). When installing the first shock absorber 4, the bolt of the first shock absorber 4 can be threadedly connected to the fixed connecting member 1 through the first connecting plate 21 and the elastic member 41 of the first shock absorber 4, or the bolt of the first shock absorber 4 can be threadedly connected to the first connecting plate 21 through the fixed connecting member 1 and the elastic member 41 of the first shock absorber 4; when installing the second shock absorber 5, the bolt of the second shock absorber 5 can be threadedly connected to the pipe clamp 3 through the second connecting plate 22 and the elastic member 41 of the second shock absorber 5, or the bolt of the second shock absorber 5 can be threadedly connected to the second connecting plate 22 through the pipe clamp 3 and the elastic member 41 of the second shock absorber 5. The above installation methods of the first shock absorber 4 and the second shock absorber 5 can be selected according to actual needs, and this embodiment does not limit this.

[0026] In order to facilitate the bolt to pass through the elastic member 41 smoothly, in this embodiment, a through hole is set in the elastic member 41 along the length direction, and a sleeve 42 for the bolt to pass through is fixed in the through hole. The length of the sleeve 42 is shorter than the length of the elastic member 41 to reserve the compression amount of the elastic member 41.

[0027] In the first installation method of the sleeve 42 and the elastic member 41 in this embodiment, both ends of the sleeve 42 are located in the through hole, that is, there is a distance between the two end faces of the elastic member 41 and the corresponding end faces of the sleeve 42, and compression is left at both ends of the elastic member 41. In this installation method, the compression at both ends of the elastic member 41 is 2 to 3 mm. In actual applications, the compression should be designed according to actual needs, and this embodiment does not limit this.

[0028] The second installation method of the sleeve 42 and the elastic member 41 is: one end face of the sleeve 42 is flush with the corresponding end face of the elastic member 41, that is, there is no distance between the end face of the sleeve 42 and the corresponding end face of the elastic member 41, and the end of the elastic member 41 that is flush with the sleeve 42 has no compression; the other end face of the sleeve 42 is located in the through hole, that is, there is a distance between the end of the sleeve 42 and the corresponding end face of the elastic member 41, and the end of the elastic member 41 that is not flush with the sleeve 42 has compression. In this installation method, the compression amount of the end of the elastic member 41 that has compression is 4 to 6 mm. In actual applications, the compression amount should be designed according to actual needs, and this embodiment does not limit this.

[0029] The designer may select the above two installation methods of the sleeve 42 and the elastic member 41 according to actual needs, and this embodiment does not limit this.

[0030] In the second installation method of the sleeve 42 and the elastic member 41 , an internal thread structure may be selectively provided in the sleeve 42 to increase the connection strength.

[0031] In this way, when installing the first shock absorber 4, place the end of the first shock absorber 4 whose sleeve 42 is flush with the elastic member 41 close to the fixed connecting member 1, and after the bolt of the first shock absorber 4 passes through the first connecting plate 21, it is threadedly connected with the sleeve 42 of the first shock absorber 4 and the fixed connecting member 1 in sequence; or place the end of the first shock absorber 4 whose sleeve 42 is flush with the elastic member 41 close to the first connecting plate 21, and after the bolt of the first shock absorber 4 passes through the fixed connecting member 1, it is threadedly connected with the sleeve 42 of the first shock absorber 4 and the first connecting plate 21 in sequence.

[0032] When installing the second shock absorber 5, place the end of the second shock absorber 5 whose sleeve 42 is flush with the elastic member 41 close to the pipe clamp 3, and pass the bolts of the second shock absorber 5 through the second connecting plate 22 and threadedly connect them with the sleeve 42 of the second shock absorber 5 and the pipe clamp 3 in sequence; or place the end of the second shock absorber 5 whose sleeve 42 is flush with the elastic member 41 close to the second connecting plate 22, and pass the bolts of the second shock absorber 5 through the pipe clamp 3 and threadedly connect them with the sleeve 42 of the second shock absorber 5 and the second connecting plate 22 in sequence.

[0033] The designer may select the installation method of the first shock absorber 4 and the second shock absorber 5 according to actual needs, and this embodiment does not limit this.

[0034] Since the elastic rubber block has the functions of shockproofing, vibration reduction, sound insulation and noise reduction, the elastic member 41 in this embodiment is preferably an elastic rubber block. Of course, a spring can also be selected, and this embodiment does not limit this.

[0035] In order to increase the connection strength, in this embodiment, the middle connecting plate 23 is preferably a 90° twist plate, and the first connecting plate 21, the middle connecting plate 23 and the second connecting plate 22 are integrally arranged.

[0036] The pipe clamp 3 in this embodiment includes two symmetrically arranged clamping members 31, and the clamping members 31 include an arc-shaped clamping section 311, a first connecting straight section 312 arranged at one end of the arc-shaped clamping section, and a second connecting straight section 313 arranged at the other end of the arc-shaped clamping section 311. When in use, the first connecting straight sections 312 of the two clamping members 31 are connected, and the second connecting straight sections 313 of the two clamping members 31 are connected, and the arc-shaped clamping sections 311 of the two clamping members 31 cooperate with each other to clamp the steel pipe c.

[0037] In this embodiment, the two first connecting straight sections 312 are connected to the second connecting plate 22. Of course, the two second connecting straight sections 313 may also be selected to be connected to the second connecting plate 22, and this embodiment does not limit this.

[0038] In this embodiment, the fixed connection member 1 is used to connect with the cab b, and the structure is various, which will not be described here.

[0039] A preferred embodiment of the steel pipe support structure of the utility model is described in detail above. The utility model is not limited to the above specific implementation methods. Various changes made by ordinary technicians in this field based on the above conception without creative labor all fall within the protection scope of the utility model.
