Description

Technical Field

[0001] The utility model belongs to the technical field of contact networks, and in particular relates to a real-time monitoring device for a contact network ratchet. Background Art

[0002] The automatic catenary tension compensation device is a crucial component of the catenary system. The efficiency and effectiveness of compensation are directly related to the magnitude of the catenary tension and the speed of fluctuations, thus impacting the performance and operational safety of the catenary system. In addition to meeting the requirements for catenary tension compensation, the ratchet compensation device must also provide excellent wire break arresting performance, effectively minimizing the impact on equipment and reducing the severity of the incident in the event of a fault (or accident). In new and revised catenary designs, ratchet compensation devices are also commonly used for compensation of center anchors with anti-channeling but not anti-breakage protection. This compensates for the shortcomings of the anti-channeling center anchor in the event of a wire break.

[0003] The main problems with the ratchet compensation device are the eccentric wear of the compensation rope of the ratchet compensation device and the ratchet body and the wire-gripping groove, and the jamming and loosening of the limiting frame. The eccentric wear of the ratchet will seriously reduce the compensation efficiency and even cause line breakage accidents while causing damage to the equipment. The jamming and loosening of the compensation device will directly lead to the deterioration of the contact network tension, and in severe cases, directly cause traffic accidents. Therefore, real-time monitoring of the status of the ratchet compensation device is of critical significance for maintaining the actual status of the ratchet compensation device. At the same time, the tension of the weight has a greater influence on the deflection of the ratchet, and in related technologies, it is impossible to accurately monitor the tension of the ratchet compensation device, and thus it is impossible to accurately monitor the status of the ratchet supplement mechanism.

[0040] Example:

[0041] See also Figures 1 to 6 The contact network ratchet real-time monitoring device in the preferred embodiment of the utility model can not only accurately collect the deflection of the ratchet in the spatial position, but also obtain the movement distance of the collection weight and the contact network component in real time, and can also accurately measure the tension on the contact network component, providing a data basis for the status judgment of the ratchet compensation mechanism.

[0042] Specifically, if Figures 1 to 6 As shown in , in a preferred embodiment of the present application, the contact network ratchet real-time monitoring device is installed on a ratchet compensation mechanism, which includes a base 5 mounted on a column 4, a pair of arms 6 rotatably connected to the base 5, and a ratchet rotatably connected between the two arms 6. The ratchet includes a large-diameter wheel 7 and small-diameter wheels 8 symmetrically arranged on either side of the large-diameter wheel 7. The outer wall of the large-diameter wheel 7 is provided with a first wire groove and at least one row of ratchet teeth arranged along the circumference. A first catenary cable 9 is wound within the first wire groove. One end of the first catenary cable 9 is wound and fixed within the first wire groove. The other end of the first catenary cable 9 extends vertically and is fixedly connected to a weight 11. A second catenary cable 10 is fixed and wound around each of the two small-diameter wheels 8. A balancing member is provided at the center of the second catenary cable 10, longitudinally spaced from the small-diameter wheel 8. Furthermore, a contact network member 14 is provided on the side of the balancing member facing away from the second catenary cable 10.

[0043] The tension monitoring mechanism includes a first tension monitoring member 301 and a second tension monitoring member 302. The top and bottom surfaces of the first tension monitoring member 301 are fixedly connected to the weight 11 and the first catenary cable 9, respectively, or the top and bottom surfaces of the first tension monitoring member 301 are embedded in the first catenary cable 9, thereby accurately measuring the tension applied by the weight 11 to the first catenary cable 9. The longitudinal ends of the second tension monitoring member 303 are fixedly connected to the balance member and the contact network member 14, respectively, or the longitudinal ends of the second tension monitoring member 303 are directly embedded in the second catenary cable 10, thereby accurately measuring the tension in the second catenary cable 10.

[0044] In actual use, since the diameters of the large-diameter wheel 7 and the small-diameter wheel 8 are both fixed and known, when the ratchet compensation mechanism is in a normal state, the ratio between the standard tension in the first catenary cable 9 and the standard tension experienced by the contact network component 14 is a fixed tension standard value. If the ratio between the actual tension in the first catenary cable 9, as measured by the first tension monitoring component 301, and the actual tension experienced by the contact network component 14, as measured by the second tension monitoring component 303, deviates from the tension standard value, it can be determined that an error exists in the state of the ratchet compensation mechanism.

[0045] It is worth noting that in the preferred embodiment of the present application, the upright posts 4 are perpendicular to the horizontal plane and extend in the vertical direction. Furthermore, the upright posts 4 are located on one side of the track, and the track extends in the longitudinal direction. Furthermore, the direction perpendicular to the longitudinal direction in the horizontal plane is the transverse direction.

[0046] Further preferably, in the preferred embodiment of the present application, in order to avoid the failure of the first tension monitoring component 301 causing the sinker 11 and the first load-bearing cable 9 to loosen, the first tension monitoring component 301 also includes at least one first tensile safety component 302. At the same time, the two ends of each first tensile safety component 302 are respectively fixedly connected to the first load-bearing cable 9 and the sinker 11. When the first tension monitoring component 301 fails, the first load-bearing cable 9 and the sinker 11 can be reconnected with the help of the first tensile safety component 302, thereby reducing the probability of the sinker 11 accidentally falling.

[0047] In more detail, in a preferred embodiment of the present application, the second tension monitoring component 303 also includes at least one second tensile safety component 304. At the same time, the two ends of each second tensile safety component 304 are respectively fixedly connected to the balance component and the contact network component 14, so as to prevent the contact network component 14 from falling when the second tensile monitoring component 303 fails.

[0048] Furthermore, in a preferred embodiment of the present application, the first tensile safety component 302 and the second tensile safety component 304 are metal ropes formed by twisting a plurality of metal wires.

[0049] More preferably, Figure 5 and Figure 6 As shown in , in a preferred embodiment of the present application, the first tension monitoring component 301 includes a housing 3011, an elastic member 3012, a connecting rod 3013, and a measuring assembly. A first connection area 3016 is provided on the bottom surface of the housing 3011, and a storage space is provided within the housing 3011. The elastic member and the measuring assembly are both provided within the storage space. Furthermore, a longitudinally extending through-hole is provided on the housing 3011, which passes through the top surface of the housing 3011 and communicates with the storage space. The connecting rod 3013 is a stepped rod structure, with a large-diameter section 3014 provided within the storage space.

Preferably, a plurality of elastic members 3012 are provided, arranged in an array between the large-diameter section 3014 and the bottom surface of the storage space.

[0050] The small-diameter section 3015 of the connecting rod 3013 extends from the through-hole, and a second connection area 3017 is provided on the extended end. A measuring assembly is fixedly connected to the large-diameter section 3014 of the connecting rod 3013 and is used to measure and calculate the tension carried by the first load-bearing cable 9 based on the displacement of the large-diameter section 3014. Preferably, the measuring assembly is a sliding rheostat.

Preferably, the second tension monitoring component 303 and the first tension monitoring component 301 have the same structure. Further preferably, the shell 3011 and the connecting rod 3013 are both metal parts, so that after the elastic member 3012 is completely broken, the large diameter section 3014 of the connecting rod 3013 can be directly clamped on the top of the accommodating space, and the metal shell 3011 and the large diameter section 3014 of the connecting rod 3013 can be used to prevent the weight 11 from falling off.

[0056] During actual use, the first transmitting end 101 transmits a ranging signal to the first receiving end 102 in real time, and accurately determines the real-time distance between the first transmitting end 101 and the first receiving end 102 based on the time when the first receiving end 102 receives the signal and the time when the first transmitting end 101 transmits the signal, thereby accurately obtaining the actual distance from the support arm 6 to the balancing mechanism. Moreover, since the setting position of the first transmitting end 101 is fixed, combined with the B-value monitoring component, the actual distance between the balancing component and the ratchet is calculated, and then the above three distances are used to form a triangle with known side lengths, and then the actual deflection angle of the ratchet can be accurately calculated through the cosine theorem.

In actual use, the large-diameter wheel 7 drives the angular displacement measuring component 205 to rotate during its rotation, and the angular displacement measuring component 205 measures the rotation angle of the large-diameter wheel 7 in real time. Since the radius of the large-diameter wheel 7 is fixed, the rotation angle of the large-diameter wheel 7 measured by the angular displacement measuring component 205 can accurately calculate the movement length of the first load-bearing rope 9 for lifting the weight 11, and then accurately measure the height of the weight 11 relative to the horizontal plane.

The balancing wheel 12 is rotatably set on the balancing bracket 13. At the same time, a third wire groove is provided on the balancing bracket 13. The second load-bearing cable 10 passes around the third wire groove, and then the load of the weight 11 is transferred to the balancing bracket 13 through the second load-bearing cable 10 to tighten the contact network component 14.

[0064] Furthermore, in a preferred embodiment of the present application, the B-value monitoring component includes at least one second laser measurement component, which also includes a third transmitting end 203 and a third receiving end 204, wherein the third transmitting end 203 is fixed to the column 4, and correspondingly, the third receiving end 204 is fixedly mounted on the balancing member.

In another preferred embodiment of the present application, the first receiving end 102 and the third receiving end 204 are the same receiving end.

[0069] In actual use, Figure 4 and Figure 5 As shown in , the first straight-line distance 16 from the center of the large-diameter wheel 7 to the center of the balance wheel 12 can be measured based on the B-value monitoring component. At the same time, the second straight-line distance 17 between the first launch port and the center of the balance wheel 12 can be accurately measured based on the deflection distance measuring component. Moreover, since the lateral distance from the first launch port to the center point bracket of the large-diameter wheel 7 is known, that is, the third straight-line distance 18 is known, the three sides of the triangle formed by the center of the large-diameter wheel 7, the center of the balance wheel 12, and the first launch port are all known. Then, based on the cosine law, the angle of the first angle 19 with the center of the large-diameter wheel 7 as the vertex can be measured, and then the deflection angle of the large-diameter wheel 7 can be accurately calculated.

[0070] Furthermore, in a preferred embodiment of the present application, the first transmitting end 101, the first receiving end 102, the second transmitting end 201, the second receiving end 202, the third transmitting end 203, the third receiving end 204, the angular displacement measurement component 205, the first tension monitoring component 301, and the second tension monitoring component 303 are all provided with power supply components. Preferably, the power supply component includes one or more of solar cells, batteries, or power supply cables to ensure the continuous and stable operation of each monitoring mechanism.

[0071] The contact network ratchet real-time monitoring device in the present invention has a simple structure, stable operation and accurate measurement. It realizes accurate monitoring of the movement of the weight 11 and the movement of the balance member by setting a first laser measurement component for accurately measuring the movement between the weight 11 and the column 4 in real time and a second laser measurement component set on the column 4 and the balance member. At the same time, by aligning the position of at least one deflection distance measuring component set on the support arm 6 and the first transmitting end 101 with the center of the large diameter wheel 7 of the ratchet, and with the actual position of the balance member measured by the second laser measurement component, the deflection angle of the large diameter wheel 7 is accurately measured. In addition, by correspondingly setting a first tension monitoring component 301 between the weight 11 and the first load-bearing cable 9 and a second tension monitoring component 303 set between the balance member and the contact network component 14, the tension in the contact member and the force between the weight 11 and the first load-bearing cable 9 are accurately measured, providing accurate data support for the status evaluation of the ratchet compensation mechanism, which has good promotion value and application prospects.
