Description
Technical Field
[0001] The utility model belongs to the technical field of mining dump trucks, and in particular relates to an unmanned mining wheel side speed acquisition component structure. Background Art
[0002] Unmanned mining vehicles are the mainstream development trend of mining production. Unmanned driving can greatly reduce manpower, improve production efficiency, reasonably control the formation of mining vehicles, and ensure safe production. Unmanned driving has extremely high requirements for the collection of mining vehicle speed data. Through the collection of speed data, the speed and operation of mining vehicles can be better controlled. The collection of speed data is mainly carried out through speed sensors and speed sensor ring gears. Therefore, the installation of speed sensors and speed sensor ring gears is very important. Reasonable installation methods are an important prerequisite for ensuring the safe and smooth operation of unmanned mining vehicles.
[0003] At present, there are different ways and methods for installing speed sensors and speed sensor ring gears. Most of them are installed by bolt connection. Since the mounting hole is larger than the outer diameter of the bolt, it is difficult to ensure the coaxiality of the speed sensor ring gear and the wheel when installing the speed sensor ring gear. When the speed sensor is installed in place, as the vehicle runs, the relative position between the speed sensor and the speed sensor ring gear will deviate, and the relative distance between the speed sensor and the speed sensor ring gear has extremely high requirements. A slight deviation will also lead to inaccuracy in the collected data, thereby affecting the control of the vehicle. Utility Model Content
[0004] The utility model aims to provide an unmanned mining vehicle wheel side speed acquisition component structure, which can accurately control the installation position of the speed sensor ring gear through interference connection, thereby realizing accurate acquisition of the mining vehicle speed.
[0005] In order to achieve the above purpose, the technical solution used in this utility model is:
[0006] The structure of the wheel speed collection component for unmanned mining vehicles includes: a speed sensor ring gear, a speed sensor bracket, a speed sensor, a wheel hub, and a caliper mounting plate; the boss of the wheel hub is arranged at the through hole of the wheel hub, the stop is located at the end of the boss, the speed sensor ring gear is connected to the boss, the speed sensor ring gear is interference connected with the boss, and the speed sensor ring gear fits the end face of the stop; the speed sensor bracket is installed on the side of the caliper mounting plate, the speed sensor is fixed on the speed sensor bracket, and the speed sensor is located directly above the speed sensor ring gear.
[0007] Furthermore, the speed sensor bracket includes: a connecting plate, a fixing plate, and an arc-shaped side plate, the ends of the connecting plate and the fixing plate are respectively connected to the sides of the arc-shaped side plate; the connecting plate and the fixing plate are respectively perpendicular to the arc-shaped side plate, and the connecting plate and the fixing plate are perpendicular to each other; the connecting plate is provided with a first connecting through hole, the fixing plate is provided with a second connecting through hole and a sensor mounting through hole, and the speed sensor is installed in the sensor mounting through hole.
[0008] Furthermore, a gap adjustment plate is installed between the base and the fixed plate of the speed sensor, and the gap adjustment plate is provided with a third connecting through hole and a gap adjustment through hole. The sensor fixing bolt passes through the base through hole, the third connecting through hole and the second connecting through hole of the speed sensor to fix the speed sensor on the fixed plate, and the speed sensor is inserted into the gap adjustment through hole and the sensor installation through hole.
[0009] Furthermore, a mounting plate through hole is provided in the middle of the caliper mounting plate, a threaded bottom hole is provided on the outside of the mounting plate through hole, a screw passes through the first connecting through hole and is connected to the threaded bottom hole, and the speed sensor bracket is fixed to the side of the caliper mounting plate.

[0011] The technical effects of the utility model include:
[0012] 1. In the utility model, the speed sensor gear ring is installed on the wheel hub through interference fit, and the installation position of the speed sensor gear ring is fixed by a stop. The interference fit can ensure the coaxiality of the speed sensor gear ring and the front wheel, and prevent the speed sensor gear ring from being eccentric and falling off due to unreliable connection.
[0013] The interference fit connection eliminates the phenomenon of the speed sensor gear ring being out of axial alignment with the front wheel caused by bolt installation, and reduces inaccurate factors when the speed sensor collects data. At the same time, the interference fit connection ensures the reliability of the installation and reduces the risk of the gear ring falling off caused by loose bolts caused by bolt connection.
[0014] 2. The connecting plate and fixing plate of the speed sensor bracket are respectively perpendicular to the arc-shaped side plates. The design of the double 90° bracket ensures the installation of the speed sensor in a limited space. At the same time, the installation position is adjusted so that the speed sensor is located directly above the speed sensor gear ring to ensure the installation requirements of the speed sensor.
[0015] 3. When the speed sensor is installed, an adjustment piece is provided. By adjusting the number of the adjustment pieces, the relative position requirements of the speed sensor and the speed sensor gear ring can be ensured during installation.
[0016] 4. The speed sensor assembly structure is a separate structure from the front wheel, which can be used for the installation of newly produced vehicles and the transformation of old products. It has high compatibility and is of great significance for the transformation and upgrading of existing vehicles in mines and the promotion of unmanned driving.

[0031] The speed sensor bracket 2 includes: a connecting plate 21, a fixing plate 22, and an arc-shaped side plate 23.

[0032] The connecting plate 21, the fixing plate 22 and the arc-shaped side plate 23 are perpendicular to each other, ensuring that the fixing plate 22 is perpendicular to the side surface of the caliper mounting plate 5 and the end surfaces of the speed sensor gear ring 1 and the wheel hub 4 respectively. The bottom of the speed sensor 3 is opposite to the side surface of the speed sensor gear ring 1, so that the speed sensor 3 is located directly above the speed sensor gear ring 1.
[0033] like Figure 5 FIG. 2 is a schematic diagram of the structure of the gap adjusting piece 6 in the utility model.
[0034] The gap adjusting sheet 6 is provided with a third connecting through hole 61 and a gap adjusting through hole 62 .
