Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to an integrated fixing device for a stroke sensor and wiring harness in the main beam of a mining truck. Background Technology

[0002] In mining operations, mining trucks undertake heavy material transportation tasks, and the secure installation of the travel sensors and wiring harnesses on their main beams is directly related to the accuracy and reliability of vehicle operation status monitoring.

[0003] Traditional travel sensor installation methods often employ simple bolt or clamp fixation. Under prolonged vibration and impact, the sensors are prone to loosening and displacement, affecting their measurement accuracy and consequently impacting vehicle safety and automated control. Furthermore, the wiring harnesses connecting the travel sensors are typically haphazardly routed and simply tied to the frame with cable ties. This method not only easily leads to friction between the wiring harness and the frame or other components during vehicle vibration, causing damage to the harness sheath and potentially short circuits or other electrical faults, but it can also cause the wiring harness to loosen and create tension between it and the travel sensor, thereby disrupting the effective connection between the two. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides an integrated fixing device for a stroke sensor and wiring harness in the main beam of a mining truck, which solves at least one of the above-mentioned technical problems.

The two ends of the pressure block are respectively slidably connected to the sliding grooves on both sides of the first cable hole, and the pressure block slides along the axial direction of the locking knob.

[0009] In one embodiment, the top surface of the pressure block, corresponding to the end position of the locking knob, is provided with a conical or spherical recess.

[0010] In one embodiment, the locking knob has a rotating head at one end located on the outer side of the upright plate, and the circumferential side of the rotating head has anti-slip texture.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves coordinated fixation of the travel sensor and wiring harness in the beam of the mining truck by setting a U-shaped mounting bracket corresponding to the width of the truck beam, and setting sensor mounting positions and cable fixing parts on the mounting bracket.

[0025] The following will be combined with the appendix Figures 1 to 9 The present invention will be further described below.

[0026] Example 1 An integrated fixing device for stroke sensors 4 and wiring harness 5 at 7 locations on the main beam of a mining truck, such as... Figure 1 As shown, it includes: a mounting bracket 1, fasteners 2, and cable fasteners 3. The mounting bracket 1 is a U-shaped structure with a downward opening, including a horizontal plate and two vertical plates. One end of the top surface of the horizontal plate is provided with a sensor mounting position 12 for mounting a stroke sensor 4, and the other end is provided with a cable fastener 3 for fixing the wire harness 5 connected to the stroke sensor 4. The bottom side of the vertical plates has two sets of horizontally arranged mounting holes 11. The inner distance between the two vertical plates corresponds to the width of the main beam 7 of the mining truck. At least two sets of fasteners 2 are respectively inserted into the two sets of mounting holes 11.

[0027] When using this fixing device, if Figure 9As shown, first, place the U-shaped opening of the mounting bracket 1 downwards onto the top of the mining truck beam 7, ensuring that the two vertical plates are tightly against both sides of the beam 7, and that the contact surfaces between the mounting bracket 1 and the beam 7 are flat. Adjust the position of the mounting bracket 1 so that the sensor mounting position 12 on the top surface of the horizontal plate is in the optimal position for the travel sensor 4 to monitor the vehicle's operating status. Then, use at least two sets of fasteners 2 (such as high-strength long bolts) to pass through the mounting holes 11 opened laterally at the bottom of the two vertical plates, and tighten them with nuts 21 (double nuts 21 can be used to prevent loosening), thereby firmly locking the mounting bracket 1 onto the beam 7, effectively resisting vibration and impact during vehicle operation. When installing the fasteners 2, the appropriate mounting holes 11 can be selected according to the structure of the beam 7, such as... Figure 9 As shown, because there is a structural hole 71 below the main beam 7 at the installation location, and the top surface of the structural hole 71 has downward-curving rounded corners at both ends, the second mounting hole 11 closest to the center of the two sets of mounting holes 11 is selected at the widest position of the corresponding plane. Then, the travel sensor 4 is installed on the sensor mounting position 12 using bolts or a special clamp, ensuring there is no loose gap between the sensor and the mounting bracket 1. Finally, the wiring harness 5 connecting the travel sensor 4 is slightly loosened along the length of the mounting bracket 1 so that it does not contact the cross plate of the mounting bracket 1, and guided to the cable fixing member 3 at the other end of the cross plate. The cable fixing member 3 (such as an adjustable wire clamp, cable tie seat, or slot structure) is used to tightly fix the wiring harness 5, preventing the wiring harness 5 from rubbing against the main beam 7 or other components or loosening during vibration. The entire installation process is simple and quick, and the integrated design ensures the coordinated fixation of the sensor and the wiring harness 5, improving the overall stability of the system. Of course, for ease of installation, the travel sensor 4 and wiring harness 5 can be fixed to the mounting bracket 1 first, and then the mounting bracket 1 can be fixed to the main beam 7 as a whole.

[0028] This utility model achieves synchronous and stable fixing and precise positioning of the travel sensor 4 and the wiring harness 5 by setting a U-shaped mounting bracket 1 corresponding to the width of the main beam 7 of the mining truck, and setting a sensor mounting position 12 and a cable fixing component 3 on the mounting bracket 1. This solves the problems of sensor loosening and displacement caused by vibration and friction damage, loosening and electrical connection failure caused by random wiring harness 5 in the traditional installation method. As a result, it improves the measurement accuracy and reliability of the travel sensor 4, extends the service life of the wiring harness 5, and ensures the safe operation of the mining truck and the stability of the automated control.

[0029] In some implementations, such as Figure 1 and Figure 2As shown, the cable fixing component 3 is an adjustable clamping mechanism, including a vertical plate 31 and a locking knob 34. The bottom surface of the vertical plate 31 is firmly fixed to the horizontal plate of the mounting frame 1 by welding or bolt connection. The vertical plate 31 is provided with a first wire passage hole 32 for threading and accommodating the wire harness 5 connecting the travel sensor 4. The locking knob 34 is threaded to the vertical plate 31, and one end of the locking knob 34 extends into the first wire passage hole 32. The sensor mounting position 12 has two threaded mounting holes 11. In other embodiments, the sensor mounting position 12 can also be a sensor mounting base or a mounting clip.

[0030] When it is necessary to secure the wire harness 5, first pass the wire harness 5 through the first wire hole 32. Then, depending on the diameter of the wire harness 5, adjust the screw-in length of the locking knob 34 so that its inner end applies radial pressure to the wire harness 5, thereby firmly pressing the wire harness 5 against the inner wall of the wire hole, achieving a reliable fixation without slippage. By setting an adjustable clamping mechanism, it can be adapted to the installation of different models of wire harness 5, improving the adaptability of the fixing device.

[0031] Preferred, such as Figure 4 As shown, the wiring harness 5 of the travel sensor 4 is a wiring harness 5 with a connector 51. At this time, the clamping mechanism clamps the connector 51 of the wiring harness 5, which makes it easier to effectively fix the wiring harness 5 and avoids damage to the cable caused by directly crimping the cable.

[0032] In some embodiments, to improve the clamping and fixing effect on the wire harness 5 and avoid damage to the wire harness 5, the inner wall structure of the first wire passage hole 32 is specially designed. Specifically, in the bottom area of ​​the first wire passage hole 32 used to support the wire harness 5, a support structure of a specific shape is provided. One implementation of this structure is a downwardly smooth concave arc surface, the radius of curvature of which is designed to adapt to the diameter range of commonly used wire harnesses 5, so that it can cover and conform to the outer surface of the wire harness 5 from below like a bracket. Another preferred implementation is as follows... Figure 2 As shown, two centrally symmetrical inclined planes 311 are constructed at the bottom of the first wire hole 32. These two inclined planes 311 intersect to form a V-shaped structure. When the locking knob 34 is not tightened, this V-shaped structure provides a natural two-point support positioning for the wire harness 5. When the locking knob 34 is tightened, the wire harness 5 is pressed downward into the V-shaped groove to form a more stable three-point clamping positioning. Moreover, due to the V-shaped structure design, it is suitable for wire harnesses 5 of different diameters.

[0033] In some embodiments, to eliminate friction between the end of the locking knob 34 and the wire harness 5, and to prevent possible twisting of the wire harness 5 or localized damage to the protective sheath of the wire harness 5 when turning the locking knob 34, such as Figure 2 and Figure 4As shown, the cable fixing component 3 also includes a pressure block 33. Both sides of the first wire passage hole 32 are provided with a sliding groove 312. The two ends of the pressure block 33 are slidably connected to the sliding grooves 312 on both sides of the first wire passage hole 32. The pressure block 33 slides along the axial direction of the locking knob 34. When the wire harness 5 passes through the first wire passage hole 32, the pressure block 33 is located between the locking knob 34 and the wire harness 5. When the locking knob 34 is screwed in, the end of the locking knob 34 presses the pressure block 33 and thus presses the wire harness 5.

[0034] This utility model, by setting sliding grooves 312 on both sides of the first wire hole 32 and configuring pressure blocks 33 that can slide along the axis of the locking knob 34, realizes that the rotational pressure of the locking knob 34 is converted into vertical contact and pressing on the wire harness 5 through the pressure blocks 33. This solves the problem of wire harness 5 twisting and local protective sheath damage caused by friction and shearing force between the end of the locking knob 34 and the surface of the wire harness 5 when the locking knob 34 is directly turned.

[0035] In some implementations, such as Figure 2 As shown, the top surface of the pressure block 33, corresponding to the end position of the locking knob 34, has a conical or spherical recess 331, and the end of the locking knob 34 has a corresponding protrusion of the recess 331. The function of the recess 331 is to form a good fit with the tip of the locking knob 34: when the locking knob 34 is screwed in, its end can naturally embed and abut against this conical or spherical recess 331. This provides a stable guide and receiving space for the end of the locking knob 34, ensuring that the point of application of the downward pressure is always accurately maintained on the central axis of the pressure block 33, preventing the pressure block 33 from getting stuck or tilting during sliding due to pressure deviation.

[0036] In some implementations, such as Figure 2 As shown, in order to facilitate turning, a rotating head is provided at one end of the locking knob 34 located outside the upright plate 31, and anti-slip texture 341 is provided on the circumferential side of the rotating head.

[0037] In some embodiments, to further improve the shock absorption performance of the fixing device and prevent the travel sensor 4 and wiring harness 5 from becoming loose, such as... Figure 3 As shown, a top rubber pad 14 is provided on the bottom surface of the horizontal plate, and a side rubber pad 15 is provided on the inner side of each of the two vertical plates.

[0038] In some implementations, such as Figure 1 As shown, to reduce weight, rectangular perforations 13 are provided in the middle of both vertical plates. To enable adjustable installation position, two sets of mounting holes 11 are respectively located on the lower left and right sides of the perforations 13. In this embodiment, each set of mounting holes 11 has four holes.

[0039] In some embodiments, to further protect the travel sensor 4 from damage by impacts from flying stones, such as... Figure 5 and Figure 6 As shown, a U-shaped sensor protective cover 6 is provided above the sensor mounting position 12. The detection end of the travel sensor 4 faces the front opening of the sensor protective cover 6. A rear guard plate 61 is provided at the rear opening of the sensor protective cover 6. A wire passage groove 611 is provided on the rear guard plate 61, and the wire harness 5 passes through the wire passage groove 611.

[0040] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 7 and Figure 8 As shown, the integrated fixing device for the stroke sensor 4 and wiring harness 5 at the main beam 7 of the mining truck provided in this embodiment is used to install the wiring harness 5 with its own connecting plate 52. Typically, the connecting plate 52 has through holes 521 at each of its four corners. In this embodiment, the cable fixing component 3 includes a mounting plate 35 for installing the wiring harness 5 with its own connecting plate 52. The mounting plate 35 has a second through hole 351 and a threaded hole 352 corresponding to the through hole 521. The wiring harness 5 passes through the second through hole 351. When fixing the wiring harness 5, a screw is passed through the through hole 521 of the connecting plate 52 and then connected to the threaded hole 352.

[0041] In summary, this utility model, by setting a U-shaped mounting bracket 1 corresponding to the width of the mining truck beam 7, and setting a sensor mounting position 12 and a cable fixing component 3 on the mounting bracket 1 in an integrated structure, achieves the coordinated fixing of the stroke sensor 4 and the wiring harness 5 on the mining truck beam 7, effectively preventing friction damage, loosening and electrical short circuit of the wiring harness 5 of the stroke sensor 4, and solving the problems of decreased measurement accuracy, easy damage to the wiring harness 5 and connection failure caused by traditional installation methods.

[0042] Components and principles not described in detail in this utility model can be implemented using various structures and principles known in the prior art.

[0043] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
