[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] like Figure 1 and Figure 2 As shown, the utility model proposes a device for detecting the forward and reverse directions of a differential lock push rod mounting column, comprising a base 1 and a mounting plate 2, a support plate being provided on the front end surface of the base 1, slide rails 3 being provided in parallel at both ends of the front end surface of the support plate in a vertical direction, the slide rails 3 being connected to a slide table 4 through a slider, a measuring component 9 being installed on the top surface of one side of the slide table 4 perpendicular to the support plate, the measuring component 9 comprising a displacement sensor arranged at the center of one side of the bottom surface of the slide table 4, a plurality of measuring heads 10 arranged around the outer circle of the displacement sensor, a detection end being provided at the bottom of the plurality of measuring heads 10, and a telescopic connection being made with the end surface of the slide table 4 through an elastic member at the top.

[0020] In the embodiment, a connecting plate 8 is fixed to the top surface of the mounting plate 2, and a first cylinder 6 is provided on the top surface of the connecting plate 8 close to the mounting plate 2. The output end of the first cylinder 6 passes through the connecting plate 8 and is connected to the slide 4 for controlling the movement of the slide 4.

[0021] In the embodiment, a protective cover 11 is also provided on the outer periphery of the front end of the mounting plate 2, and a second cylinder 7 is installed on the top surface of the connecting plate 8 on the side away from the mounting plate 2. The output end of the second cylinder 7 passes through the connecting plate 8 and is connected to the front inner wall of the protective cover 11, and the edges on both sides of the front end surface of the mounting plate 2 are slidably connected to the protective cover 11 through symmetrically arranged guide components 5.

[0022] In the embodiment, the guide assemblies 5 on both sides include two coaxial lines, and one end of the bottom is fixed to a guide base on the front end surface of the mounting plate 2. A guide rod is slidably inserted into the two guide bases, and both ends of the guide rod are respectively connected to a fixed seat, and the other end of the fixed seat is fixedly connected to the inner wall of the side end of the protective cover 11 by bolts.

[0023] In the embodiment, the detection end portion is provided with a contoured groove for matching and contacting with the push rod shaft of the differential lock, and whether the push rod is correctly installed is determined by the degree of matching.

[0024] In the embodiment, the protective cover 11 is made of transparent material to facilitate observation of the detection status.

[0025] The working principle of a device for detecting the forward and reverse direction of the differential lock push rod mounting column based on the first embodiment is as follows: during the detection, the second cylinder 7 descends first before the first cylinder 6 descends to prevent the operator from putting his hand in during the detection and causing personal injury. The second cylinder 7 descends first to drive the protective cover 11 to descend. The protective cover is arranged at the front end of the mounting plate 2, which can effectively play a protective role. The slide 4 and the measuring component 9 are connected by elastic parts, which can make the movement smoother when the first cylinder 6 drives the rise or fall. A profiling groove is arranged at the front detection end of the measuring head 10. When the differential push rod is installed correctly, the convex groove of the push rod can match the profiling groove, and the displacement sensor value is within the qualified range at this time; if the push rod is installed reversely, the profiling groove cannot match the push rod, and the displacement sensor value is outside the qualified range at this time, indicating that there is an abnormality, and the displacement sensor needs to send an alarm to remind the operator to handle it.

[0026] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
