Description

Technical Field

[0001] This utility model relates to the field of concrete mixing tank drive technology, and in particular to a reinforced mixer truck reducer base structure. Background Technology

[0002] A concrete mixer truck is a special truck used to transport ready-mixed concrete for construction. The principle is to equip a cylindrical mixing drum on a heavy-duty truck chassis to transport ready-mixed concrete. During transportation, the mixing drum rotates continuously to prevent the concrete from solidifying. The reducer is an extremely important component in the operation of a concrete mixer truck.

[0003] The reducer of a concrete mixer truck is a key transmission device installed on the concrete mixer truck to drive the mixing drum. Its core function is to convert the high-speed, low-torque output of the engine into a low-speed, high-torque suitable for the operation of the mixing drum, while bearing the weight of the mixing drum and the impact load during transportation. The existing reducers are all installed by fixing them to the vehicle body with a base and bolts.

[0004] During vehicle acceleration, braking, bumping, and going up and down slopes, the inertial force generated by the tank will be applied to the reducer base and fastening bolts through the connecting flange. In practical applications, there have been many tank drop accidents caused by cracks in the reducer base. Traditional base structures are insufficient to withstand the impact load under complex road conditions. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reinforced mixer truck reducer base structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reinforced mixer truck reducer base structure includes a housing body, with base blocks installed at the bottom of the housing body. Two sets of base blocks are symmetrically installed at the bottom of the housing body. The base blocks are rectangular in shape and widened on both sides. A first stiffener is provided at the top of the housing body, and a second stiffener is provided on one side of the first stiffener. One end of the first stiffener is fixed to the housing body, and one end of the second stiffener is also fixed to the housing body. A water tank mounting stiffener is provided on one side of the housing body, with its bottom end fixed to the top of both the first and second stiffeners. The water tank mounting stiffener, the first stiffener, and the second stiffener form a frame structure. The water tank mounting stiffener has two sets of openings. Bolt holes are provided in the base blocks. A connecting flange is connected to one side of the housing body, and an internal gear is provided on the inner wall of the connecting flange.

[0008] As a further improvement of this utility model: several groups of bolt holes are provided, the bolt holes are arranged in a linear longitudinal direction, and there are multiple rows of bolt holes.

[0009] As a further improvement of this utility model: the vertical direction of the first stiffener is narrower at the top and wider at the bottom, and the vertical direction of the second stiffener is also narrower at the top and wider at the bottom.

[0010] As a further improvement of this utility model: the base block is made of cast iron, and the first and second stiffening plates are also made of cast iron.

[0011] As a further improvement of this utility model: a reinforcing cavity is provided at the bottom of the main body of the shell, a third base plate is provided in the reinforcing cavity, and a fourth rib is provided on one side of the third base plate.

[0012] As a further improvement of this utility model: the bottom of the base block is provided with several sets of buffer cavities, the positions of which are adapted to the bolt holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The frame structure formed by the water tank mounting stiffeners, the first stiffener, and the second stiffener increases strength. The widening of the base block enhances the impact resistance of the base. The widened base block significantly increases the contact area with the frame and the distribution of support points, allowing the reducer to more effectively distribute the weight of the mixing drum and the huge impact loads generated by braking, turning, and bumps during driving. This greatly reduces local stress concentration, improves the overall structural rigidity, prevents deformation or damage caused by excessive load, increases durability and operational reliability under complex road conditions, and prevents the base block from cracking due to impact loads, which could lead to a tank falling accident, thus greatly increasing safety.

[0015] 2. Using cast iron to make the base block, first stiffener, and second stiffener can improve fatigue resistance and service life, effectively resist long-term alternating loads, and significantly extend service life.

[0016] 3. The buffer cavity at the bottom of the base block can form a flexible buffer area, which can disperse the stress peak at the root of the thread, prevent the base block from cracking or deforming due to stress concentration, and at the same time avoid bolt breakage.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] A reinforced mixer truck reducer base structure, such as Figure 1-4 As shown, the device includes a shell body 1, with a base block 3 installed at the bottom of the shell body 1. There are two sets of base blocks 3, which are symmetrically installed at the bottom of the shell body 1. The base blocks 3 are rectangular in shape and widened on both sides. A first stiffener 6 is provided at the top of the shell body 1, and a second stiffener 7 is provided on one side of the first stiffener 6. One end of the first stiffener 6 is fixed to the shell body 1, and one end of the second stiffener 7 is fixed to the shell body 1. A water tank mounting stiffener 5 is provided on one side of the shell body 1. The bottom end of the water tank mounting stiffener 5 is fixed to the top of the first stiffener 6 and the second stiffener 7 respectively. The water tank mounting stiffener 5, the first stiffener 6, and the second stiffener 7 can form a frame structure. The water tank mounting stiffener 5 has two sets of openings. The base block 3 has bolt holes 2. A connecting flange 8 is connected to one side of the shell body 1, and an internal gear 9 is provided on the inner wall of the connecting flange 8.

[0026] During use, bolts can be installed and fixed to the water tank through the openings in the water tank mounting stiffener 5. An output flange can be connected to one side of the main body 1, allowing connection to the tank of the mixer truck for torque transmission. The base block 3 connects and fixes to the vehicle frame, securing the reducer. The reducer body can be installed via the connecting flange 8 and internal gear 9, enabling the reducer's function. Bolts can be tightened through the bolt holes 2 in the base block 3. The frame structure formed by the water tank mounting stiffener 5, the first stiffener 6, and the second stiffener 7 increases strength. The widening of base block 3 enhances the impact resistance of the base. The widened base block 3 significantly increases the contact area with the frame and the distribution of support points, allowing the reducer to more effectively distribute the weight of the mixing drum and the huge impact load generated by braking, turning, and bumping during driving. This greatly reduces local stress concentration, improves the overall structural rigidity, prevents deformation or damage caused by excessive load, increases durability and operational reliability under complex road conditions, and prevents the base block 3 from cracking due to impact load, which could lead to a drum falling accident, thus greatly increasing safety.

[0027] To reduce the risk of bolt shearing, such as Figure 2 As shown, there are several groups of bolt holes 2, which are arranged in a linear longitudinal direction and have multiple rows.

[0028] In use, the bolt holes 2 of the base block 3 facilitate the connection of bolts and nuts for fixed installation. The multiple rows of bolt holes 2 arranged in a linear longitudinal direction can effectively disperse the inertial impact load on the bolts, reducing the risk of bolt shearing.

[0029] To optimize the force distribution, such as Figure 1 , 2 As shown, the first stiffener 6 is narrower at the top and wider at the bottom, and the second stiffener 7 is also narrower at the top and wider at the bottom.

[0030] In use, the vertical orientation of the first stiffener 6 and the second stiffener 7, which is narrower at the top and wider at the bottom, can enhance the structural strength, optimize the stress distribution, and make the material distribution more reasonable.

[0031] To improve fatigue resistance and service life, such as Figure 1 , 2 As shown, the base block 3 is made of cast iron, and the first stiffener 6 and the second stiffener 7 are also made of cast iron.

[0032] When in use, using cast iron to make the base block 3, the first stiffening plate 6, and the second stiffening plate 7 can improve fatigue resistance and service life, effectively resist long-term alternating loads, and significantly extend service life.

[0033] To increase load-bearing capacity, such as Figure 4As shown, a reinforcing cavity is provided at the bottom of the main body 1 of the shell, a third base plate 11 is provided in the reinforcing cavity, and a fourth rib plate 12 is provided on one side of the third base plate 11.

[0034] In use, the third base plate 11 and the fourth stiffener 12 are arranged in a cross shape. The third base plate 11, the fourth stiffener 12 and the reinforcing cavity can form a multi-frame structure, thereby effectively improving the load-bearing capacity and enhancing the overall stability.

[0035] Example 2

[0036] To increase the fixed strength, refer to Figure 4 A reinforced mixer truck reducer base structure, this embodiment makes the following improvements compared to embodiment 1: the bottom of the base block 3 is provided with several sets of buffer cavities 10, the position of the buffer cavities 10 is adapted to the bolt holes 2;

[0037] When in use, the position of the buffer cavity 10 is adapted to the bolt hole 2. When the bolt is pre-tightened, local high stress will be generated. The buffer cavity 10 at the bottom of the base block 3 can form a flexible buffer area, which can disperse the stress peak at the root of the thread, prevent the base block 3 from cracking or deforming due to stress concentration, and at the same time avoid the bolt from breaking.

[0038] The above description is only a preferred embodiment of the present utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of the present utility model is not limited thereto.
