Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vehicle-mounted measurement fixed structure, specifically relating to a proximity switch bracket for a rigid mining truck. Background Technology
[0002] Rigid mining trucks, abbreviated as "gangka," are mainly sold in mining areas such as Xinjiang, Inner Mongolia, and Russia. Gangkas operate in harsh environments, which significantly impact the performance of the sensors.
[0003] The rigid mining truck needs to use proximity switches to detect the position of the superstructure to determine whether the lifting is completed or ended. Therefore, the sensor is very important. Currently, the existing installation method is to fix it directly to the frame. The vibration of the frame is directly transmitted to the sensor. When the rigid mining truck is running on unpaved roads, the frame is subjected to an instantaneous impact acceleration of >18g. As a critical position sensor, the proximity switch is prone to high failure rate due to traditional installation method. According to statistics, 90% of the damage is caused by broken solder joints or detachment of internal components.
[0004] In response to this situation, current vibration reduction solutions typically use rubber damping blocks to reduce the vibration transmitted from the chassis. However, in the environment of drastic temperature differences in mining areas, rubber damping blocks are prone to embrittlement or creep, leading to failure. Utility Model Content
[0005] To address the shortcomings of existing technologies, a rigid proximity switch bracket for mining trucks is provided to solve the problem that conventional sensors are easily damaged by vibration during installation and fixation.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A proximity switch bracket for a rigid mining truck, comprising:
[0007] Mounting bracket, used for connecting to the vehicle frame;
[0008] Mounting plates are spaced apart above the fixed base, and the proximity switches are fixed on the mounting plates;
[0009] Several vibration isolation supports are provided, with both ends of the vibration isolation supports being fixed to the fixed base and the mounting plate, respectively.
[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:
[0011] The proximity switch is mounted on a mounting plate, which is connected to a mounting base via multiple vibration-damping supports. The mounting plate and proximity switch are suspended above the mounting base without contacting it. The mounting base is connected to the vehicle frame. Vibrations transmitted from the vehicle frame can be filtered by the vibration-damping supports, resisting vertical and lateral swaying transmitted from the vehicle frame and preventing damage to the proximity switch.
[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:
[0013] In one embodiment, the vibration isolation support is a steel wire rope, with both ends of the steel wire rope bent and connected to the outside of the fixed base and the mounting plate.
[0014] The vibration isolation support is made of steel wire rope. The rigidity of the steel wire rope can provide good support. At the same time, the steel wire rope is bent and connected to the mounting plate and fixed base. The elasticity of the steel wire rope can effectively filter the vibration transmitted from the bottom.
[0015] In one embodiment, the wire rope comprises multiple strands of wire spirally twisted together.
[0016] By twisting multiple strands of steel wire into a steel wire rope, the friction between the twisted steel wire ropes can be fully utilized to filter vibrations, and the elastic potential energy of the steel wires can be used to counteract the vibrations.
[0017] In one embodiment, the diameter of the steel wire is 0.6-1 mm.
[0018] In one embodiment, the surface of the steel wire is coated with an anti-corrosion and heat-insulating coating.
[0019] The anti-corrosion and heat-insulating layer coated on the surface of the steel wire can increase the temperature resistance of the steel wire rope and extend its service life.
[0020] In one embodiment, a plurality of the vibration isolation supports are evenly spaced along the circumference of the fixed base.
[0021] Vibration isolation supports spaced evenly in the circumference can ensure that vibrations are transmitted from all directions and that the mounting plate can maintain good stability.
[0022] In one embodiment, a wire-passing hole is provided at the center of the fixed base corresponding to the proximity switch, and the diameter of the wire-passing hole is larger than the outer diameter of the proximity switch extending into it.
[0023] In one embodiment, the mounting plate has screw holes, the proximity switch is screwed into the screw holes, and the proximity switch is fitted with fastening nuts that abut against both sides of the mounting plate.
[0024] In one embodiment, a bracket is also included, and the mounting base is fixed to the bracket by a plurality of fasteners, the bracket being fixed to the vehicle frame.
[0025] In one embodiment, the bracket is an L-shaped bracket, the fixing seat is disposed on the horizontal plane of the L-shaped bracket, and the vertical plane of the L-shaped bracket is connected and fixed to the vehicle frame. Attached Figure Description

[0037] Example
[0038] like Figure 1-3 As shown, the present invention provides a rigid mining truck proximity switch bracket 4 7, which includes: a fixed base 1, a mounting plate 2 and multiple vibration isolation support members 3.
[0039] The mounting base 1 is used to connect to the vehicle frame. The mounting plates 2 are spaced above the mounting base 1. The proximity switch 4 is fixed on the mounting plate 2. In this embodiment, the vibration isolation support 3 is strip-shaped and there are 4 of them. The two ends of the vibration isolation support 3 are fixed to the mounting base 1 and the mounting plate 2 respectively, so as to isolate the mounting plate 2 and the proximity switch 4 from the base below.
[0040] The proximity switch 4 is mounted on the mounting plate 2. The mounting plate 2 is connected to the fixed base 1 through multiple vibration isolation supports 3. The fixed base 1 is connected to the vehicle frame. The vibration transmitted from the vehicle frame can be filtered by the vibration isolation supports 3 to resist the vertical and lateral sway transmitted from the vehicle frame and avoid damage to the proximity switch 4.
[0041] Specifically, the vibration isolation support 3 is a steel wire rope. The two ends of the steel wire rope are bent and connected to the outside of the fixed base 1 and the mounting plate 2. The two ends of the steel wire rope can be fixed to the sides of the fixed base 1 and the mounting plate 2 by welding or other methods. By using a steel wire rope as the vibration isolation support 3, the rigidity of the steel wire rope provides good support. Simultaneously, by bending the steel wire rope and connecting it to the mounting plate 2 and the fixed base 1, the elasticity of the steel wire rope effectively filters vibrations transmitted from the bottom. Furthermore, the steel wire rope has a certain degree of flexibility.
[0042] Specifically, the wire rope is formed by spirally twisting multiple strands of steel wire. When the multiple strands of steel wire are tightly bonded together to form a wire rope, they can form a rigid bundle. By using multiple strands of steel wire to form a wire rope, the friction between the twisted steel wires can be fully utilized to filter vibrations, and the elastic potential energy of the steel wires can also be used to counteract the vibrations. Moreover, by forming a wire rope by twisting the steel wires, when the vibration is small, the relative friction between the steel wires exhibits the characteristics of a soft spring, absorbing low-frequency small vibrations. When the vibration is large, the contact between the steel wires is larger, the stiffness is increased, and it exhibits the characteristics of a hard spring, suppressing large vibrations.
[0043] Specifically, depending on the magnitude of the impact force that the frame needs to withstand, the diameter of the steel wire is selected to be 0.6-1mm, and the steel wire can be made of 8-10 strands twisted into a steel wire rope to meet the vibration isolation requirements of the proximity switch 4.
[0044] To ensure good overall protection of the wire rope, the surface of the wire is coated with an anti-corrosion and heat-insulating coating, which can be a fluorocarbon coating. The anti-corrosion and heat-insulating layer coated on the surface of the wire can increase the temperature resistance of the wire rope and improve its service life.
[0045] In this embodiment, several vibration isolation supports 3 are evenly spaced along the circumference of the fixed base 1. The evenly spaced vibration isolation supports 3 can ensure that vibrations are transmitted from all directions and that the mounting plate 2 can maintain good stability.
[0046] To facilitate the connection of the proximity switch 4, the bottom of the proximity switch 4 is used for wiring, and the top of the proximity switch 4 is used for the corresponding sensing area. The center of the mounting base 1 is provided with a wire hole 5 corresponding to the proximity switch 4. The diameter of the wire hole 5 is larger than the outer diameter of the proximity switch 4 extending into it. That is, the diameter of the wire hole 5 is larger than the outer diameter of the bottom end of the proximity switch 4 extending into the wire hole 5, so that when vibration occurs, the wire hole 5 will not interfere with the proximity switch 4. Moreover, the wire hole 5 allows the wire of the proximity switch 4 to pass through the wire hole 5 and be connected to the equipment in the vehicle.
[0047] To facilitate the installation of the proximity switch 4, a screw hole is provided in the mounting plate 2. The proximity switch 4 is screwed into the screw hole. The proximity switch 4 is fastened with fastening nuts that abut against both sides of the mounting plate 2. The proximity switch 4 is locked onto the mounting plate 2 by the two fastening nuts.
[0048] To facilitate the connection and fixation of the mounting base 1 to the vehicle frame, a bracket 7 is also included. The mounting base 1 is fixed to the bracket 7 by several fasteners 6. The bracket 7 is fixed to the vehicle frame. The mounting base 1 is detachably connected to the bracket 7 by the fasteners 6. The bracket 7 can be fixed to the vehicle frame by welding or by fasteners 6, so that the mounting base 1 can be connected to the bracket 7 by disassembly, making subsequent disassembly more flexible and convenient.
[0049] Specifically, the bracket 7 is an L-shaped bracket 7, the fixing seat 1 is set on the horizontal plane of the L-shaped bracket 7, and the vertical plane of the L-shaped bracket 7 is connected and fixed to the vehicle frame. Through the L-shaped bracket 7, the entire fixing seat 1 and the proximity switch 4 on the mounting plate 2 can be installed on the side of the vehicle frame, such as the inner side of the vehicle frame. The vibration isolation support 3 is evenly spaced in a circumferential direction in a relatively safe position, which can ensure that vibrations are transmitted from all directions and the mounting plate 2 can maintain good stability.
[0050] like Figure 3As shown, the bracket 7 is also provided with a through hole 8 corresponding to the wire hole 5 opened on the fixed base 1, so that the wire connecting to the proximity switch can pass through the wire hole 5 and the through hole 8.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
