Description

Technical Field

[0001] This utility model belongs to the field of excavator technology, specifically relating to a displacement sensor mounting bracket. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The excavator's working device is controlled by the extension and retraction of hydraulic cylinders. To better observe the extension and retraction distance of the cylinders and calculate relevant parameters such as the amount of hydraulic oil entering and exiting, and the magnitude of the force, a displacement sensor is needed to measure the extension and retraction distance. The distance is determined by extending a stainless steel or nylon wire through a pull rod below the displacement sensor.

[0004] Currently, displacement sensors are generally fixed using pre-designed bolt holes, which are then bolted together to assemble with the hydraulic cylinder. However, due to the insufficient compatibility between the design of the sensor's bolt holes and the surface structure of the hydraulic cylinder, a large gap easily forms between the sensor and the cylinder after assembly, preventing a tight fit and causing instability in the mounting base itself.

[0005] Furthermore, excavators often need to be in special postures during actual operation, such as digging, lifting, and rotating. In these situations, the position and angle of the hydraulic cylinders change dynamically. The reliance on bolt holes for sensor fixing lacks flexibility and makes it difficult to maintain stable sensor installation under these special postures, easily leading to displacement. Moreover, the excavator's operating environment is complex. During operation, the machine continuously generates high-frequency vibrations, and when digging hard materials or dealing with sudden resistance, the hydraulic cylinders are also subjected to instantaneous impact loads. Under the influence of vibration and impact, sensors, which already have gaps in their fit and poor fixing stability, are not only prone to loosening and displacement, but in severe cases, may even fall off. This makes it impossible to meet the sensor installation stability requirements of different working conditions in excavation operations, and it is also difficult to adapt to the changing environmental conditions in field operations. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a displacement sensor mounting bracket, which facilitates the fixing of displacement sensors, offers greater flexibility in use, ensures the stability of displacement sensor installation, and withstands impact and vibration, making it suitable for various working conditions and environments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A displacement sensor mounting bracket includes a support plate, a strut, a support beam, a shelf, and a displacement sensor mounting plate. One end of the support plate is connected to the displacement sensor mounting plate, and the other end of the support plate is connected to the shelf. The upper end of the support plate is connected to the support beam, and the upper end of the support beam is connected to one end of the strut. The other end of the strut is connected to the support plate. A first mounting hole is provided on the support plate, and a second mounting hole is provided at one end of the displacement sensor mounting plate.

[0008] As a further technical solution, a displacement sensor is provided at the upper end of the displacement sensor mounting plate, the displacement sensor is provided with mounting holes, and a number of second mounting holes are provided at intervals on the displacement sensor mounting plate.

[0009] As a further technical solution, the second mounting hole is aligned with the mounting hole on the displacement sensor. After alignment, the displacement sensor and the displacement sensor mounting plate are connected by the first fixing bolt, the first fixing nut and the washer.

[0010] As a further technical solution, the first fixing bolt passes through the second mounting hole and the mounting hole on the displacement sensor, a washer is fitted on one end of the first fixing bolt, and the first fixing nut is installed on the other end of the first fixing bolt.

[0011] As a further technical solution, the first mounting holes are symmetrically arranged on the support plate, and several first mounting holes are arranged at intervals.

[0012] As a further technical solution, the other end of the displacement sensor mounting plate is provided with a circular hole, which is aligned with the first mounting hole on the support plate. After alignment, the support plate and the displacement sensor mounting plate are connected by a second fixing bolt, a second fixing nut and a washer.

[0013] As a further technical solution, the second fixing bolt passes through the first mounting hole and the circular hole on the displacement sensor, a washer is fitted on one end of the second fixing bolt, and the second fixing nut is installed on the other end of the second fixing bolt.

[0014] As a further technical solution, one end of the strut is fixedly connected to the support plate, and the other end of the strut is fixedly connected to the support beam.

[0015] As a further technical solution, the lower end of the support beam has a U-shaped groove, and one end of the shelf is located in the U-shaped groove.

[0016] As a further technical solution, one end of the shelf is fixedly connected to the support plate, and the lower end of the shelf has a V-shaped groove, which is located at the upper end of the oil cylinder.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are: The lower end of the shelf of this utility model is provided with a V-shaped groove, which can fit against the upper end of the oil cylinder to achieve initial positioning. The U-shaped groove at the lower end of the support beam is adapted to connect with one end of the shelf. One end of the support rod is fixed to the support plate and the other end is fixed to the support beam, thus forming a stable support frame. At the same time, the displacement sensor mounting plate is connected to the support plate through a bolt assembly, and the displacement sensor is connected to the mounting plate through a bolt assembly, thus realizing the fixation of the displacement sensor.

[0018] The support plate of this utility model is symmetrically provided with a plurality of spaced first mounting holes.

By selecting different positions of the first mounting holes and the circular hole to match, the fixed position of the mounting plate on the support plate can be flexibly adjusted. The other end of the displacement sensor mounting plate is also provided with a plurality of spaced second mounting holes. The mounting holes on the displacement sensor can be aligned and connected with different second mounting holes, thereby adjusting the position of the displacement sensor on the mounting plate. When the excavator working device is in a special posture that results in limited space, the position of the displacement sensor can be flexibly adjusted to avoid spatial obstacles and ensure that the displacement sensor is in a suitable measurement position.

Even in the operation scenario of high-frequency vibration of excavator or instantaneous impact load on hydraulic cylinder, it can stably fix the displacement sensor, prevent it from displacement, loosening or even falling off, and ensure installation stability.

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a displacement sensor mounting bracket, such as... Figure 1 As shown, the system includes a support plate 1, a strut 2, a support beam 3, a shelf 4, and a displacement sensor mounting plate 5. One end of the support plate 1 is connected to the displacement sensor mounting plate 5, and the other end of the support plate 1 is connected to the shelf 4. The upper end of the support plate 1 is connected to the support beam 3, and the upper end of the support beam 3 is connected to one end of the strut 2. The other end of the strut 2 is connected to the support plate 1. A first mounting hole 11 is provided on the support plate 1, and a second mounting hole 51 is provided at one end of the displacement sensor mounting plate 5.

[0024] Specifically, the lower end of the placement plate 4 is provided with a V-shaped groove, which can fit against the upper end of the oil cylinder to achieve initial positioning. The U-shaped groove at the lower end of the support beam 3 is adapted to connect with one end of the placement plate 4. One end of the support rod 2 is fixed to the support plate 1 and the other end is fixed to the support beam 3, thus forming a stable support frame. At the same time, the displacement sensor mounting plate 5 is connected to the support plate 1 through a bolt assembly, and the displacement sensor 6 is connected to the mounting plate through a bolt assembly, thus fixing the displacement sensor 6.

[0025] The support plate 1 has a plurality of spaced first mounting holes 11 symmetrically arranged. One end of the displacement sensor mounting plate 5 has a circular hole that can be aligned with the first mounting holes 11. By selecting different positions of the first mounting holes 11 and the circular hole to match, the fixed position of the mounting plate on the support plate 1 can be flexibly adjusted. The other end of the displacement sensor mounting plate 5 also has a plurality of spaced second mounting holes 51. The mounting holes on the displacement sensor 6 can be aligned and connected with different second mounting holes 51, thereby adjusting the position of the displacement sensor 6 on the mounting plate. When the excavator working device is in a special posture that results in limited space, the position of the displacement sensor 6 can be flexibly adjusted to avoid spatial obstacles and ensure that the displacement sensor 6 is in a suitable measurement position.

[0026] Washers are used in conjunction with the fixing bolts during the connection process. The washers can fill the tiny gaps in the connection parts, enhance the fit between the components, prevent loosening caused by the gaps, and reduce the direct friction between the bolts and the surface of the components, protecting the integrity of the connection surface. This gives the bracket excellent vibration and impact resistance. Even in operating scenarios where the excavator experiences high-frequency vibration or the cylinder is subjected to instantaneous impact loads, the displacement sensor 6 can be stably fixed, preventing displacement, loosening, or even falling off, thus ensuring installation stability.

[0027] The robust support frame and adjustable function allow the bracket to meet the installation requirements of excavators in different working postures such as digging, lifting, and rotating. By adjusting the structural position to adapt to changes in the cylinder angle, it can also adapt to complex environmental conditions in field operations and resist external vibrations, impacts, and other interference factors, providing stable and reliable support for the displacement sensor 6. This ensures that the displacement sensor 6 can work normally under different working conditions and environments, meeting the excavator's requirements for the accuracy of measuring the cylinder extension distance.

[0028] like Figure 2 and Figure 3 As shown, a displacement sensor 6 is mounted on the upper end of the displacement sensor mounting plate 5. The displacement sensor 6 has mounting holes, and several second mounting holes 51 are spaced apart on the displacement sensor mounting plate 5. The second mounting holes 51 are aligned with the mounting holes on the displacement sensor 6. After alignment, the displacement sensor 6 and the displacement sensor mounting plate 5 are connected by a first fixing bolt 8, a first fixing nut 7, and a washer. The first fixing bolt 8 passes through the second mounting holes 51 and the mounting holes on the displacement sensor 6. A washer is fitted onto one end of the first fixing bolt 8, and the first fixing nut 7 is installed on the other end of the first fixing bolt 8.

[0029] Specifically, in the installation of the excavator displacement sensor 6, the displacement sensor 6 is first placed on the upper surface of the displacement sensor mounting plate 5, so that the mounting hole of the displacement sensor 6 faces the direction of the second mounting hole 51 on the displacement sensor mounting plate 5. Since there are several second mounting holes 51 on the displacement sensor mounting plate 5, the most suitable set of second mounting holes 51 can be selected according to the height and angle of the displacement sensor 6 required for this measurement.

[0030] After the mounting hole on the displacement sensor 6 is fully aligned with the selected second mounting hole 51, take the first fixing bolt 8 and pass it through the second mounting hole 51 from below the displacement sensor mounting plate 5, and then continue through the mounting hole on the displacement sensor 6. Then, put a washer on the end of the first fixing bolt 8 that extends out of the displacement sensor 6, and tighten the first fixing nut 7 clockwise to the end of the first fixing bolt 8 until the nut and the washer are in tight contact and there is no sign of looseness. At this time, the displacement sensor 6 is firmly fixed on the displacement sensor mounting plate 5 through the cooperation of the bolt, nut and washer, which is ready for subsequent measurement of the extension and retraction distance of the hydraulic cylinder.

[0031] The first mounting holes 11 are symmetrically arranged on the support plate 1, with several holes spaced apart. The other end of the displacement sensor mounting plate 5 has a circular hole aligned with the first mounting holes 11 on the support plate 1. After alignment, the support plate 1 and the displacement sensor mounting plate 5 are connected by a second fixing bolt 10, a second fixing nut 9, and a washer. The second fixing bolt 10 passes through the first mounting hole 11 and the circular hole on the displacement sensor 6. A washer is fitted onto one end of the second fixing bolt 10, and the second fixing nut 9 is installed on the other end of the second fixing bolt 10.

[0032] Specifically, based on the current posture of the excavator's working device and the installation space requirements, the fixed position of the displacement sensor mounting plate 5 on the support plate 1 is determined, and the corresponding first mounting hole 11 is selected. After aligning the circular hole of the displacement sensor mounting plate 5 with the selected first mounting hole 11, the second fixing bolt 10 is taken and passed through the first mounting hole 11 from one side of the support plate 1, and then through the circular hole on the displacement sensor mounting plate 5. Next, a washer is fitted onto one end of the second fixing bolt 10 extending from the displacement sensor mounting plate 5, ensuring that the washer completely covers the edge of the circular hole. Finally, the second fixing nut 9 is tightened at the end of the second fixing bolt 10. Through the tightening force of the bolt and nut, the displacement sensor mounting plate 5 is tightly connected to the support plate 1, and the position of the displacement sensor mounting plate 5 can be adjusted by changing the position of the first mounting hole 11 according to subsequent changes in working conditions.

[0033] One end of the strut 2 is fixedly connected to the support plate 1, and the other end of the strut 2 is fixedly connected to the support beam 3. The lower end of the support beam 3 has a U-shaped groove, and one end of the shelf 4 is located in the U-shaped groove.

[0034] Specifically, first, align one end of the strut 2 with the preset connection position of the support plate 1, and fix the two together by welding to ensure that the connection is seamless and the force is stable; then align the other end of the strut 2 with the corresponding position of the support beam 3, and fix the two together by welding, so that the strut 2, the support plate 1 and the support beam 3 form a triangular support structure.

[0035] Since the lower end of the support beam 3 has a U-shaped groove, one end of the placement plate 4 is slowly placed into the U-shaped groove. The position of the placement plate 4 is adjusted so that the two fit tightly. Then, the placement plate 4 is fixedly connected to the inner wall of the U-shaped groove of the support beam 3 by welding, thus completing the overall assembly of the support structure. This effectively disperses external forces and provides a stable foundation for the subsequent overall installation of the bracket.

[0036] like Figure 4 As shown, one end of the shelf 4 is fixedly connected to the support plate 1, and the lower end of the shelf 4 has a V-shaped groove, which is located at the upper end of the oil cylinder.

[0037] Specifically, during the installation of the bracket and the excavator cylinder, the V-shaped groove at the lower end of the placement plate 4 is aligned with the corresponding position at the upper end of the cylinder. The placement plate 4 is then placed down so that the V-shaped groove fits against the upper surface of the cylinder. The limiting effect of the V-shaped groove is used to achieve the initial positioning of the placement plate 4 on the cylinder, determine the appropriate position of the support structure, and then fix the support structure to the cylinder using ropes, wires, etc.

[0038] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
