Description

Technical Field

[0001] This utility model relates to the field of tank processing technology for transport vehicles, specifically a welding and rotating device for the tank of a concrete mixer transport vehicle. Background Technology

[0002] The concrete mixer truck tank is the most crucial component of the entire vehicle, and its manufacturing quality directly impacts the truck's lifespan and mixing performance. In particular, the welding quality of the tank's inner and outer joints and the positioning welding of the blades significantly affect its overall quality. Firstly, the inner and outer joints of the tank are circumferential welds. Without auxiliary equipment, this welding requires three methods: flat welding, vertical welding, and overhead welding. These three welding methods demand a high level of skill from the workers; otherwise, a single circumferential weld will exhibit varying quality depending on the welding method used. Secondly, the positioning welding of the blades inside the tank involves a double-helix structure. Workers must position the blades circumferentially along the tank's perimeter during assembly, making the operation extremely difficult. Furthermore, the limited space inside the tank and the considerable weight of each blade further complicate the assembly process. Both the circumferential welds of the tank and the positioning welding of the helical blades are manufactured circumferentially, making the process quite challenging. Utility Model Content

[0003] The purpose of this invention is to propose a welding rotation device for concrete mixer truck tanks. Based on the rotating characteristics of the tank, it effectively solves the difficulties of multi-mode welding and blade assembly, and improves the quality and efficiency of tank processing.

[0004] The technical solution adopted by this utility model is: a welding and rotating device for a concrete mixer truck tank, including a working platform and two sets of bearing assemblies fixed on the working platform. Each set of bearing assemblies is equipped with a long roller, and the two long rollers are arranged in parallel relative to each other.

[0005] The distance between the two long rollers is smaller than the outer diameter of the tank, and the circumferential surfaces of the two long rollers are supported on the lower side of the outer circumferential surface of the tank.

[0006] Two single-stage reducers are fixed on the work platform. The single-stage reducers are connected to the corresponding long rollers through universal drive shafts. The two single-stage reducers are connected through a synchronous transmission mechanism, so that the two long rollers rotate synchronously in the same direction.

[0007] An electric drive mechanism is fixed on the working platform. The electric drive mechanism is connected to a first-stage reducer and drives the long roller to rotate the tank body, so that the circumferential weld and blade welding position of the tank body are always located at the bottom.

[0008] As a preferred embodiment, the work platform is equipped with support rollers for supporting the long rollers.

[0009] As a preferred embodiment, there are at least two sets of support rollers distributed along the length of the long roller.

[0010] As a preferred embodiment, the mounted bearing assembly includes a mounted bearing bracket and a mounted bearing mounted within the mounted bearing bracket, with the end of the long roller passing through the corresponding mounted bearing.

[0011] As a preferred embodiment, the primary reducer includes reducer I and reducer II. Reducer I has a non-reduced output shaft and a reduced output shaft, wherein the non-reduced output shaft is connected to the end of the synchronous transmission mechanism, and the reduced output shaft is connected to the universal drive shaft.

[0012] As a preferred embodiment, the electric drive mechanism includes a two-stage reducer and a motor mounted on the working platform. The output shaft of the motor is connected to the input shaft of the two-stage reducer, and the output shaft of the two-stage reducer is connected to the input shaft of reducer I.

[0013] As a preferred option, the synchronous transmission mechanism is a rigid coupling or a gear transmission mechanism.

[0014] As a preferred option, the circumferential surface of the long roller is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This concrete mixer truck tank welding rotation device uses a motor and a two-stage reduction gear to rotate two long rollers simultaneously, driving the tank body to rotate as well. The circumferential weld is performed while the tank body rotates, ensuring the welding position is always at the bottom. This allows for the most comfortable flat welding method, effectively ensuring weld quality. Simultaneously, the circumferential rotation of the tank ensures that the internal blades are also at the bottom during assembly and positioning welding, facilitating blade handling and welding for workers, reducing labor intensity, and effectively guaranteeing the welding quality between the blades and the tank body. This effectively ensures the quality of the workpiece, reduces after-sales issues, and enhances the product's market influence. Attached Figure Description

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising," "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0024] To more clearly describe the specific structural components of the welding rotating device for the concrete mixer truck tank, in conjunction with the attached... Figure 1-3 This embodiment is described as follows:

[0025] like Figure 1-3 As shown, a concrete mixer truck tank welding rotation device includes a working platform 1 and two sets of bearing assemblies fixed on the working platform 1. Each bearing assembly is equipped with a long roller 3, and the two long rollers 3 are arranged in parallel relative to each other. The distance between the two long rollers 3 is less than the outer diameter of the tank 12, and the circumferential surfaces of the two long rollers 3 are supported on the lower side of the outer circumferential surface of the tank 12. Two primary reducers are fixed on the working platform 1, and the primary reducers are connected to the corresponding long rollers 3 through universal drive shafts 8. The two primary reducers are connected through a synchronous transmission mechanism 9, so that the two long rollers 3 rotate synchronously and in the same direction. An electric drive mechanism is fixed on the working platform 1, and the electric drive mechanism is connected to the primary reducers and drives the long rollers 3 to rotate the tank 12, so that the circumferential weld and blade welding position of the tank 12 are always located at the bottom.

[0026] During use, the tank body 12 is placed on the upper side of two long rollers 3 for welding and assembly. The two long rollers 3 rotate simultaneously, causing the tank body 12 to rotate circumferentially, so that the circumferential weld of the tank body 12 and the blade positioning weld are always at the bottom for flat welding and blade assembly, without the need to adjust the working position.

[0027] The long roller 3 is cylindrical in shape and has no breaks along its length. To ensure the stability and accuracy of rotating the tank 12, anti-slip textures are provided on the circumference of the long roller 3 to contact the tank 12.

[0028] Because the tank body 12 is heavy, in order to prevent the long roller 3 from deforming during long-term use, a support roller 5 is provided on the working platform 1 to support the long roller 3; the support roller 5 is distributed along the length direction of the long roller 3 in no less than two groups, and each group of support roller 5 includes two horizontally opposed support rollers, and the support rollers are symmetrical about the axis of the long roller 3.

[0029] The mounted bearing assembly includes a mounted bearing bracket 2 and a mounted bearing 4 installed in the mounted bearing bracket 2. The end of the long roller 3 passes through the corresponding mounted bearing 4. For example, the working platform 1 is provided with a total of 4 sets of mounted bearing brackets 2, which are designed at both ends of each long roller 3.

[0030] The single-stage reducer is used to change direction and reduce speed. The single-stage reducer includes reducer I6 and reducer II7. Reducer I6 is a dual-output shaft reducer, which has a non-reduced output shaft (the non-reduced output shaft can be coaxially connected to the input shaft of reducer I6) and a reduced output shaft. The non-reduced output shaft is connected to the end of the synchronous transmission mechanism 9, and the reduced output shaft is connected to the universal drive shaft 8.

[0031] The electric drive mechanism includes a two-stage reducer 10 and a motor 11 mounted on the working platform 1. The output shaft of the motor 11 is connected to the input shaft of the two-stage reducer 10, and the output shaft of the two-stage reducer 10 is connected to the input shaft of reducer I6. The two-stage reducer 10 is used to cooperate with the first-stage reducer to reduce the speed, so that the long roller 3 has a suitable speed. In the process of power transmission, the motor 11 is first reduced in speed by the two-stage reducer 10, and then the power is transmitted to reducer I6. Reducer I6 transmits the reduced power to one long roller 3 through its reduced output shaft. Simultaneously, reducer I6 transmits the unreduced power to another long roller 3 through its unreduced output shaft. Both long rollers 3 only undergo two-stage reduction, so their speeds can be kept consistent.

[0032] The synchronous transmission mechanism 9 is used to ensure that the two long rollers 3 rotate synchronously. Specifically, the synchronous transmission mechanism 9 is a rigid coupling or a gear transmission mechanism.

[0033] The parts not described in detail in the above embodiments are existing technologies.

[0034] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
