Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular relates to a mounting bracket for hydraulic valve blocks. Background Technology

[0002] Hydraulic valve blocks are one of the common components in hydraulic systems. They are mainly used to control the flow direction, pressure and flow rate of hydraulic oil. Hydraulic valve blocks are usually fixed to the vehicle frame.

[0003] There are two main methods for fixing hydraulic valve blocks to the chassis. One method involves drilling threaded holes in the chassis and securing the valve block with bolts. However, since the chassis used to fix the valve block is laser-cut and is bulky, it cannot be machined on a machine tool to drill the threaded holes, often requiring secondary tapping, which severely impacts production efficiency. The other method involves drilling through holes in the chassis, passing bolts through the hydraulic valve block and the through holes, and securing them with nuts. While this method does not require additional threaded holes, the nuts are prone to loosening due to vibration during use. Moreover, if one nut loosens, it can cause other nuts to loosen, affecting normal operation. Utility Model Content

[0004] In view of the defects or deficiencies in the prior art, this utility model provides a mounting bracket for hydraulic valve blocks, which can ensure the reliability of the connection between the hydraulic valve block and the vehicle frame without machining threaded holes on the vehicle frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embodiment of this utility model provides a mounting bracket for a hydraulic valve block, including a bracket plate and a fixing plate, which are located on both sides of a vehicle frame. The bracket plate is hung on the vehicle frame, and the hydraulic valve block is set in close contact with the bracket plate. The vehicle frame has multiple first through holes, the bracket plate has multiple second through holes, and the fixing plate has multiple threaded holes. The first through holes, second through holes, and threaded holes are all set to correspond to the mounting holes on the hydraulic valve block. Bolts pass through the mounting holes, second through holes, and first through holes in sequence and are threadedly connected to the threaded holes.

[0006] Furthermore, the support plate is a rectangular plate, and the length of the support plate is set according to the length of the hydraulic valve block, and the support plate completely covers the bottom surface of the hydraulic valve block.

[0007] Furthermore, a first central hole is formed in the middle of the surface of the support plate.

[0008] Furthermore, hooks are provided at the top of both sides of the support plate, and the hooks are integrally formed with the support plate by laser cutting.

[0009] Furthermore, the hook is an inverted L-shape, comprising a horizontal plate and a vertical plate. One end of the horizontal plate is connected to the support plate, and the other end is connected to the top of the vertical plate. The bottom end of the vertical plate extends downward.

[0010] Furthermore, the distance between the vertical plate and the support plate is equal to the thickness of the vehicle frame.

[0011] Furthermore, the top edge of the fixing plate is a straight edge, flush with the outer edge of the vehicle frame.

[0012] Furthermore, the two sides and the bottom edge of the fixing plate are both arc-shaped edges that curve inwards.

[0013] Furthermore, the threaded hole is located at the intersection of two adjacent sides.

[0014] Furthermore, a second central hole is provided in the middle of the surface of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets up a fixing plate and opens threaded holes on the fixing plate that correspond to the mounting holes on the hydraulic valve block, so that the bolts are threadedly connected to the threaded holes on the fixing plate, thereby fixing the hydraulic valve block. It is not necessary to open threaded holes on the frame, which reduces the processing cost. In addition, it avoids the situation where the nut loosens due to vibration and other reasons when using nut connection, thus ensuring the reliability of the connection between the hydraulic valve block and the frame.

[0016] 2. This utility model sets up a bracket plate and a hook on the bracket plate, which can be hung on the frame. The bracket plate supports the bolts. When the bolts vibrate due to the vibration of the vehicle pad, part of the force will be transmitted to the bracket plate, preventing the bolts from damaging the first through hole on the frame and damaging the frame.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] A typical embodiment of this utility model is as follows: Figure 1 and Figure 2 As shown, a mounting bracket for a hydraulic valve block includes a bracket plate 1 and a fixing plate 2. The bracket plate 1 has multiple second through holes 101, which correspond to mounting holes on the hydraulic valve block 3. The fixing plate 2 has multiple threaded holes 201, which also correspond to mounting holes on the hydraulic valve block 3. During installation, the bracket plate 1 and fixing plate 2 are placed on both sides of a vehicle frame 4. The vehicle frame 4 has pre-drilled first through holes corresponding to mounting holes on the hydraulic valve block 3. The first through holes are respectively connected to the second through holes 101 and the threaded holes 201 on both sides. The hydraulic valve block is then mounted on the first through hole. 3. Place it on the bracket plate 1, so that the mounting hole on the hydraulic valve block 3 corresponds to the second through hole 101 on the bracket plate 1. Pass the bolt 5 through the mounting hole, the second through hole 101 and the first through hole in sequence, and finally thread it into the threaded hole 201, thereby realizing the fixed connection between the hydraulic valve block 3 and the frame 4. By setting the fixing plate 2 and opening the threaded hole 201 on the fixing plate 2, the bolt 5 is threaded into the threaded hole 201, thereby fixing the hydraulic valve block 3. It is not necessary to open the threaded hole on the frame 4, which reduces the processing cost. In addition, it avoids the situation where the bolt 5 falls off due to the loosening of the nut when using nut connection.

[0020] Specifically, such as Figure 3 As shown, the support plate 1 is a rectangular plate. The length of the support plate 1 is set according to the length of the hydraulic valve block 3, so that the support plate 1 can completely cover the bottom surface of the hydraulic valve block 3 and support the hydraulic valve block 3. The support plate 1 has multiple second through holes 101, which correspond one-to-one with the mounting holes on the hydraulic valve block 3, so that the bolts 5 can pass through the mounting holes and the second through holes 101 respectively, and finally be threaded to the threaded holes 201 on the fixing plate 2. A first central hole 102 is provided in the middle of the surface of the support plate 1. While ensuring the structural strength of the support plate 1, the first central hole 102 occupies as much of the surface of the support plate 1 as possible, thereby greatly reducing the weight of the support plate 1.

[0021] Furthermore, hooks are provided at the top of both sides of the bracket plate 1. The hooks are integrally formed with the bracket plate 1 by laser cutting. The hooks are bent towards the rear of the bracket plate 1 and are inverted L-shaped, including a horizontal plate 103 and a vertical plate 104. One end of the horizontal plate 103 is connected to the bracket plate 1, and the other end is connected to the top of the vertical plate 104. The bottom end of the vertical plate 104 extends downward. The distance between the vertical plate 104 and the bracket plate 1 is equal to the thickness of the frame 4. During installation, the back of the bracket plate 1 is close to the outer surface of the frame 4. At this time, the hooks can be hung on the outer edge of the frame 4. The diameter of the second through hole 101 on the bracket plate 1 is equal to the diameter of the bolt 5, so that the bracket plate 1 supports the bolt 5. When the bolt 5 vibrates due to vehicle bumps, part of the force will be transmitted to the bracket plate 1, preventing the bolt from damaging the first through hole on the frame 4 during vibration and damaging the frame 4.

[0022] The fixing plate 2 is located on the side of the frame 4 away from the hydraulic valve block 3. The fixing plate 2 has multiple threaded holes 201, which correspond to the multiple mounting holes on the hydraulic valve block 3. The shape of the fixing plate 2 is not unique, as long as it can completely cover the mounting holes on the hydraulic valve block 3.

[0023] In this embodiment, as Figure 4 As shown, the top edge of the fixing plate 2 is a straight edge, which can be flush with the outer edge of the frame 4 after installation. The two sides and the bottom edge of the fixing plate 2 are curved edges that are bent inward. The threaded hole 201 is opened at the intersection of the two adjacent sides. This structure can reduce the weight of the fixing plate 2. A second central hole 202 is opened in the middle of the surface of the fixing plate 2. Without affecting the strength of the fixing plate 2, the second central hole 202 occupies as large a surface area as possible, thereby further reducing the weight of the fixing plate 2.

[0024] Working principle First, when cutting the frame corresponding to the mounting holes of the hydraulic valve blocks, a first through hole is made on the frame at the position corresponding to the mounting holes of the hydraulic valve blocks. The diameter of the first through hole is slightly larger than the bolt diameter. In addition, a bracket plate and a fixing plate are processed by laser cutting. The connecting plates at the top of both sides of the bracket plate are bent backward to form hooks, and threaded holes are processed on the fixing plate. When installing the hydraulic valve block, hang the bracket plate on the frame, aligning the second through hole on the bracket plate with the first through hole on the frame. Place the hydraulic valve block tightly against the bracket plate, aligning the mounting hole on the hydraulic valve block with the second through hole on the bracket plate. Place the fixing plate on the side of the frame away from the hydraulic valve block, aligning the threaded hole on the fixing plate with the first through hole on the frame. Pass the bolts through the mounting hole of the hydraulic valve block, the second through hole on the bracket plate, and the first through hole on the frame in sequence, and thread them into the threaded hole on the fixing plate. When the bolts are tightened, the hydraulic valve block presses against the bracket plate, the bracket plate presses against the frame, and the fixing plate also presses against the frame. When the corresponding torque is reached, the hydraulic valve block is firmly fixed to the frame.

[0025] By setting a fixing plate and opening threaded holes on the fixing plate that correspond to the mounting holes on the hydraulic valve block, the bolts are threadedly connected to the threaded holes on the fixing plate, thereby fixing the hydraulic valve block. There is no need to open threaded holes on the frame, which reduces processing costs. In addition, it avoids the situation where the nut loosens due to vibration and other reasons when using nut connection, thus ensuring the reliability of the connection between the hydraulic valve block and the frame.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
