[0002] Mixer trucks are typically equipped with an oil pump, which drives the mixing drum to rotate. An oil pump crossbeam assembly is also usually installed on the mixer truck to fix and support the oil pump, ensuring stable operation. However, existing oil pump crossbeam assemblies have poor adaptability to different working environments; therefore, there is an urgent need to provide an oil pump crossbeam assembly with better installation adaptability. Utility Model Content

[0003] The purpose of this invention is to provide a crossbeam device for an oil pump in a mixer truck, which has good installation adaptability.

[0005] In some embodiments, the oil pump mounting base includes a first mounting hole, and the beam assembly includes a pipe beam passing through the first mounting hole, wherein the pipe beam is rotatably connected to the first mounting hole during oil pump assembly.

[0006] In some embodiments, during the assembly of the oil pump, the oil pump mounting base is slidably connected to the pipe beam through the first mounting hole.

[0007] In some embodiments, the beam assembly includes support plate assemblies disposed at both ends of the tube beam, the support plate assemblies being connected to the frame mounting assembly.

[0008] In some embodiments, the support plate assembly includes support plates disposed at both ends of the tube beam, one of the support plate and the frame mounting assembly being provided with a first waist hole and the other being provided with a third mounting hole, the first waist hole being bolted to the third mounting hole, and the length direction of the first waist hole extending longitudinally.

[0009] In some embodiments, the support plate assembly further includes a first reinforcing rib disposed on the support plate.

[0010] In some embodiments, the tube beam is a hollow tube with openings at both ends, and the beam assembly further includes a sealing plate that closes the openings.

[0011] In some embodiments, the mixer truck oil pump crossbeam assembly further includes a cover plate for protecting the drive shaft, the cover plate being connected to the oil pump mounting base.

[0028] Concrete mixer trucks are important engineering vehicles equipped with a mixing drum for transporting and mixing concrete. To achieve the rotation of the mixing drum, a hydraulic pump is typically used as the power source. The hydraulic pump crossbeam is a key component that supports and secures the pump, ensuring stable operation and consequently, more stable drum operation. Currently, most common hydraulic pump crossbeams are fixed welded structures. While these provide stable support and allow for minor adjustments to the pump's forward / backward and left / right positions, the adjustment range is limited, and the pump's angle cannot be adjusted, making it difficult to adapt to different vehicle models or power transmission requirements.

[0029] This utility model addresses the problem of poor installation adaptability of oil pump crossbeam devices in existing technologies by providing a mixer truck oil pump crossbeam device, as described above. Figures 1-3 As shown, the oil pump crossbeam assembly includes: an oil pump mounting base 1, a beam assembly 2, and a frame mounting assembly 3. The oil pump mounting base 1 is used to install the oil pump and is mounted on the beam assembly 2. The frame mounting assembly 3 is connected to the beam assembly 2 and the mixer truck frame respectively. During the oil pump assembly process, the oil pump mounting base 1 is rotatably connected to the beam assembly 2.

[0030] In the oil pump crossbeam device provided by this utility model, the oil pump mounting base 1 is mounted on the beam assembly 2, and the beam assembly 2 is connected to the vehicle frame through the frame mounting assembly 3, thereby connecting the oil pump crossbeam device to the vehicle frame. During the oil pump assembly process, the oil pump mounting base 1 can rotate relative to the beam assembly 2, thereby allowing the oil pump mounted on the oil pump mounting base 1 to rotate relative to the beam assembly 2, realizing the adjustment of the angle of the oil pump relative to the vehicle frame. This allows the oil pump to adapt to power transmission at different angles, improving the installation adaptability of the oil pump crossbeam device.

[0031] In some implementations, see Figure 2 As shown, the oil pump mounting base 1 includes a first mounting hole 101, and the beam assembly 2 includes a pipe beam 201 passing through the first mounting hole 101. During the oil pump assembly process, the pipe beam 201 is rotatably connected to the first mounting hole 101. According to a preferred embodiment of the oil pump crossbeam device of this utility model, the upper part of the oil pump mounting base 1 has a first mounting hole 101, which is a circular hole. The pipe beam 201 is cylindrical and passes through the first mounting hole 101, allowing the oil pump mounting base 1 to rotate relative to the pipe beam 201, thereby achieving angle adjustment of the oil pump mounting base 1. Of course, the ability of the oil pump mounting base 1 to rotate relative to the beam assembly 2 is not limited to the above embodiment; for example, the oil pump mounting base 1 and the beam assembly 2 can be hinged together.

[0032] Furthermore, the pipe beam 201 passes through the first mounting hole 101 of the oil pump mounting base 1. During the oil pump assembly process, the oil pump mounting base 1 can slide along the extension direction of the pipe beam 201. For example, referring to... Figures 1-2As shown, the oil pump mounting base 1 can move a wide range of left and right along the pipe beam 201, further improving the installation adaptability of the oil pump crossbeam device.

[0033] In some embodiments, when the oil pump mounting base 1 is adjusted to a suitable angle and moved to a suitable position on the pipe beam 201, the oil pump mounting base 1 is fixed relative to the pipe beam 201. According to a preferred embodiment of the present invention, after the oil pump mounting base 1 is adjusted to a suitable angle and position and the oil pump assembly is completed, the oil pump mounting base 1 is welded to the pipe beam 201, so that the oil pump can be fixed relative to the frame, ensuring the stability of the oil pump operation.

[0034] Of course, the oil pump mounting base 1 and the pipe beam 201 can also be connected by U-bolts, adhesive bonding, etc., as long as the oil pump mounting base 1 and the pipe beam 201 can be fixed.

[0035] In some implementations, see Figure 1 As shown, the oil pump crossbeam device provided by this utility model also includes a cover plate 4, which is connected to the upper part of the oil pump mounting base 1 to protect the drive shaft that is connected to the oil pump. The connection methods between the cover plate 4 and the oil pump mounting base 1 include, but are not limited to, welding, snap-fitting, and bonding. According to a preferred embodiment of this utility model, a second mounting hole 102 is provided on the upper part of the oil pump mounting base 1, and a fourth mounting hole is correspondingly provided on the cover plate 4. The second mounting hole 102 and the fourth mounting hole are connected by bolts, thereby connecting the cover plate 4 to the oil pump mounting base 1.

[0036] In some embodiments, the oil pump mounting base 1 also includes a hollow structure 103, see [link to relevant documentation]. Figure 2 As shown, the hollow structure is a through hole opened on the oil pump mounting base 1, which saves materials, reduces the production and manufacturing cost of the oil pump mounting base 1, and reduces the weight of the oil pump mounting base 1, making it convenient for installation.

[0037] According to a preferred embodiment of the present invention, referring to... Figure 1 and Figure 2 As shown, the oil pump mounting base 1 includes a base plate and side plates disposed on both sides of the base plate. The base plate and side plates can be an integral structure, for example, made by a bending process; or they can be a separate structure, for example, the side plates are welded to both sides of the base plate. The side plates have a first mounting hole 101 for connecting to the pipe beam 201 and a second mounting hole 102 for connecting to the cover plate 4. A perforated structure 103 can also be formed on the side plates. The base plate has a fifth mounting hole for mounting the oil pump.

[0038] In some embodiments, the beam assembly 2 includes support plate assemblies disposed at both ends of the tube beam 201, and the support plate assemblies are connected to the frame mounting assembly 3.

[0039] Further, see Figure 1 and Figure 2 As shown, the support plate assembly includes support plates 203 disposed at both ends of the tube beam 201. One of the support plates 203 and the frame mounting assembly 3 is provided with a first waist hole 204, and the other is provided with a third mounting hole 302. The first waist hole 204 is bolted to the third mounting hole 302, and the length direction of the first waist hole 204 extends longitudinally. In one embodiment, the support plate 203 is provided with the first waist hole 204, and the frame mounting assembly 3 is provided with the third mounting hole 302. The first waist hole 204 is bolted to the third mounting hole 302, and the length direction of the first waist hole 204 extends longitudinally.

[0040] It should be noted that the waist hole is shaped with semicircles at both ends and a rectangle in the middle. The distance between the centers of the two semicircles is the length of the waist hole. Therefore, the length direction of the waist hole is the extension direction of the line connecting the centers of the two semicircles. Figure 2 As shown, the length of the first waist hole 204 extends longitudinally, that is, it extends in the vertical direction, so that the beam assembly 2 can move up and down relative to the frame, thereby adjusting the vertical installation position of the oil pump.

[0041] In some implementations, see Figure 2 As shown, the support plate assembly also includes a first reinforcing rib 205 disposed on the support plate 203 to enhance the strength of the support plate 203 and ensure the stable operation of the oil pump. Furthermore, the first reinforcing rib 205 can be disposed on the side of the support plate 203 away from the frame mounting assembly 3, and the number of first reinforcing ribs 205 can be one or more.

[0042] In some implementations, see Figure 1 and Figure 2 As shown, the tube beam 201 is a hollow tube with openings at both ends. The beam assembly 2 also includes a sealing plate 202 that is closed on the opening, which further saves materials, reduces the production cost of the beam assembly 2, and reduces the weight of the beam assembly 2, making it easier to install.

[0043] In some implementations, tube beams 201 of different lengths can be used for different frame distances. Alternatively, in one embodiment, the length of tube beam 201 can be adjusted to accommodate different frame distances. For example, tube beam 201 includes multiple branch tube beams, each branch tube beam having multiple bolt holes, and the branch tube beams are connected by bolts.

[0044] In some implementations, see Figure 1 and Figure 3As shown, the frame mounting assembly 3 includes a mounting plate 301 connected to the beam assembly 2. The mounting plate 301 is provided with a second waist hole 304 for connecting to the frame. The length direction of the second waist hole 304 extends in the front-rear direction, thereby enabling the frame mounting assembly 3 to move back and forth relative to the frame, and thus enabling the adjustment of the front and rear mounting position of the oil pump.

[0045] In a preferred embodiment, see Figures 1-3 As shown, the beam assembly 2 includes a tubular beam 201 and support plates 203 disposed at both ends of the tubular beam 201. The support plates 203 are provided with first waist holes 204. The mounting plate 301 is L-shaped, and a third mounting hole 302 and a second waist hole 304 are respectively provided on both sides of the mounting plate 301. The first waist hole 204 is bolted to the third mounting hole 302, thereby installing the mounting plate 301 to the beam assembly 2. The second waist hole 304 is connected to the vehicle frame. Through the above technical solution, the vertical and horizontal positions of the oil pump relative to the vehicle frame can be adjusted.

[0046] In some implementations, see Figure 3 As shown, the frame mounting assembly 3 also includes a second reinforcing rib 303 disposed on the mounting plate 301, thereby enhancing the strength of the mounting plate 301. Furthermore, the second reinforcing rib 303 may be disposed on the side of the mounting plate 301 away from the oil pump mounting seat 1, and the number of second reinforcing ribs 303 may be one or more.

[0047] According to a preferred embodiment of the oil pump crossbeam device of this utility model, combined with Figures 1-3As shown, the oil pump crossbeam assembly includes an oil pump mounting base 1, a beam assembly 2, a frame mounting assembly 3, and a cover plate 4. The beam assembly 2 includes a tube beam 201 and support plate assemblies disposed at both ends of the tube beam 201. The tube beam 201 is a hollow tube with openings at both ends. A sealing plate 202 is installed at the opening to close the opening. The tube beam 201 passes through the first mounting hole 101 of the oil pump mounting base 1, so that the oil pump mounting base 1 can rotate and move left and right relative to the tube beam 201, thereby adjusting the angle and left and right position of the oil pump. After the angle and left and right position of the oil pump are adjusted to the appropriate position, the oil pump mounting base 1 is fixedly connected to the tube beam 201. The support plate assembly includes support plates 203 connected to both ends of the tube beam 201 and a first reinforcing rib 205 disposed on the support plates 203. A first waist hole 204 is provided on the support plate 203, extending vertically. The frame mounting assembly 3 is connected to the beam assembly 2 through the first waist hole 204, allowing adjustment of the oil pump's vertical position. The frame mounting assembly 3 includes a mounting plate 301 and a second reinforcing rib 303 disposed on the mounting plate 301. A third mounting hole 302 and a second waist hole 304 are provided on the mounting plate, extending horizontally. The first waist hole 204 of the support plate 203 is bolted to the third mounting hole 302 of the mounting plate 301. The second waist hole 304 is used to connect to the frame, thereby allowing adjustment of the oil pump's horizontal position. A cover plate 4 is connected to the upper part of the oil pump mounting base 1 to protect the drive shaft that is connected to the oil pump. Therefore, by providing the oil pump crossbeam device, the angle of the oil pump can be adjusted to adapt the oil pump to power transmission at different angles. At the same time, the up-down, left-right, and front-back positions of the oil pump can also be adjusted, thereby adapting the oil pump to the transmission interface of different mixer trucks.

[0048] Based on this, the present invention also provides a mixer truck, including the aforementioned mixer truck oil pump crossbeam device. In some embodiments, the mixer truck includes a vehicle body with a frame, a mixing drum mounted on the vehicle body, an oil pump for driving the mixing drum to rotate, and an oil pump crossbeam device connected to the frame, with the oil pump mounted on the oil pump crossbeam device.

[0049] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
