Description
Technical Field
[0001] The utility model belongs to the technical field of rail transit detection, and particularly relates to a detachable dust collection device for a rigid catenary of rail transit. Background Art
[0002] The overhead catenary is a special form of power transmission line erected above the subway line and is an important equipment for urban railways. Reliable and uninterrupted electric energy is provided for electric passenger cars through the direct contact between the catenary and the pantograph carbon slide plate. Therefore, ensuring the uninterrupted power supply of the overhead catenary and maintaining the good dynamic characteristics of the pantograph-catenary relationship are important objectives and tasks for the maintenance of the catenary.
[0003] The maintenance of the catenary requires the use of catenary wear detection equipment, and among them, the maintenance part involves the collection of dust on the overhead catenary.
[0004] The traditional dust collection device is directly fixedly installed on the catenary wear detection equipment. And when the catenary wear detection equipment moves along the catenary, the catenary is dusted due to the fitting and friction between the two, and the dust is collected by the dust collection device directly fixedly installed on the catenary wear detection equipment. After the dust collection device is full of dust, the entire catenary wear detection equipment needs to be removed from the catenary, and then the catenary wear detection equipment is turned upside down as a whole, so as to pour out the dust in the dust collection device.
[0005] In the above technology, because the dust collection device is fixedly connected to the catenary wear detection equipment, after the dust collection device is full of dust, the catenary wear detection equipment needs to be removed from the catenary, and then the dust dumping operation is carried out, and then it is reinstalled on the catenary. One removal and one installation result in a long time spent on cleaning the dust and a slow cleaning efficiency. In addition, when the equipment is turned upside down, it is easy to cause damage to the equipment. Summary of the Utility Model
[0006] The utility model provides a detachable dust collection device for a rigid catenary of rail transit, aiming at that after the dust in the dust collection device is full, the catenary wear detection equipment still remains on the catenary.

Specific embodiments
[0028] In order to easily understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.
[0029] As Figure 1-6 shown, a detachable dust collection device for a rigid catenary of rail transit includes a catenary wear detection device 1. A dust collection box 11 is detachably installed on the catenary wear detection device 1, and the opening 111 on the dust collection box 11 faces vertically upward. The dust collection box 11 is located below the traveling mechanism 12 on the catenary wear detection device. A sweeper 13 in contact with the catenary is provided on the catenary wear detection device, and is used to sweep the dust on the catenary into the dust collection box 11 through the sweeper 13, and then detach the dust collection box 13 from the catenary wear detection device, so as to achieve the purpose of directly cleaning the dust without disassembling the catenary wear detection device on the catenary.
[0030] Adopting the above solution, the purpose is that when the traveling mechanism 12 is traveling, the dust on the catenary falls into the dust collection box 11 due to the friction of the traveling mechanism 12. The dust collection box 11 is detached from the catenary wear detection device 1, the dust is poured out and then installed on the catenary wear detection device 1, so as to achieve the purpose of cleaning the dust without overall disassembling the catenary wear detection device 1 on the catenary.
[0031] The catenary wear detection device 1 includes a support frame 14. The traveling mechanism 12 includes two mounting plates 121. The support frame 14 is respectively hinged to the two mounting plates 121, and there is a gap between the two mounting plates 121. The dust collection box 11 is arranged on the support frame 14, and the gap corresponds to and communicates with the top of the dust collection box 11.
[0032] The sweeper 13 is installed on the mounting plate 121, and the installation direction of the sweeper 13 is perpendicular to the traveling direction of the traveling mechanism 12, and the sweeping direction of the sweeper 13 is parallel to the traveling direction of the traveling mechanism 12.
[0033] A dust collection groove 141 is formed on the support frame 14, and the dust collection box 11 is slidably sleeved in the dust collection groove 141.
[0034] A locking mechanism is installed on the support frame 14. The locking mechanism locks the dust collection box 11 after it slides in the dust collection groove 141 to ensure that the dust collection box 11 is properly installed in the dust collection groove 141.
[0035] The locking mechanism is a spring positioning lock pin 15. An installation hole 142 is formed at the bottom of the support frame 14, and a pin hole 1411 is installed at the bottom of the dust collection groove 141. The spring positioning lock pin 15 is arranged in the installation hole 142. When the spring positioning lock pin 15 is inserted into the pin hole 1411 from the installation hole 142, the dust collection box 11 is properly installed in the dust collection groove 141 at this time.
[0036] With the above solution, when the dust collection box 11 is pushed into the dust collection groove 141, that is, when the pin hole 1411 and the installation hole 142 are not aligned, the spring positioning lock pin 15 always presses against the bottom of the dust collection box 11 until the pin hole 1411 and the installation hole 142 are aligned. Then, the spring positioning lock pin 15 is inserted into the pin hole 1411 to ensure that the dust collection box 11 is properly installed in the dust collection groove 141. When the dust collection box 11 needs to be pulled out from the dust collection groove 141, at this time, only need to hold the spring positioning lock pin 15 by hand and pull out the spring positioning lock pin 15 from the pin hole 1411.
[0037] Furthermore, the spring positioning lock pin 15 includes a spring 151 and a pin shaft 152 with a collar. The spring 151 is sleeved on the pin shaft 152, and one end of the spring 151 is connected to the pin shaft 152, and the other end is connected to the installation hole 142.
[0038] With the above solution, when the dust collection box 11 is pushed into the dust collection groove 141, that is, when the pin hole 1411 and the installation hole 142 are not aligned, the pin shaft 152 always presses against the bottom of the dust collection box 11 until the pin hole 1411 and the installation hole 142 are aligned. Then, the pin shaft 152 is inserted into the pin hole 1411 in the extended state of the spring 151 to ensure that the dust collection box 11 is properly installed in the dust collection groove 141. When the dust collection box 11 needs to be pulled out from the dust collection groove 141, at this time, only need to hold the collar by hand and pull out the pin shaft 152 from the pin hole 1411, and at this time the spring 151 is in a compressed state.
[0039] It should be noted that for the present utility model,
[0040] (1) The traveling mechanism 12 provided on the present utility model is the same as the traveling mechanism provided on a wear detection device for rigid overhead contact lines in rail transit, with the publication number CN 220039384 U, which was applied by our company on April 13, 2023. Therefore, in the present utility model, the specific structure and driving method of the traveling mechanism 12 will not be elaborated in detail herein.
[0041] (2) The entire catenary wear detection device moves along the π-shaped busbar (the π-shaped busbar is a device for installing the catenary, and the traveling mechanism 12 in this solution travels together on the π-shaped busbar and the catenary).
[0042] The working principle of the present utility model is as follows:
[0043] When the traveling mechanism 12 is traveling, the dust on the catenary is swept by the sweeper 13 (the sweeper 13 sweeps the dust on the catenary as the traveling mechanism 12 travels) and falls into the dust collection box 11 through the opening 111 on the dust collection box 11. The dust collection box 11 is disassembled from the catenary wear detection device 1, the dust is poured out, and then it is installed on the catenary wear detection device 1 again (specifically: pull down the collar to disengage the pin shaft 152 from the pin hole 1411. At this time, the dust collection box 11 is pulled out from the gap between the two mounting plates 121. After pouring out the dust in the integrated box 11, the dust collection box 11 is sleeved into the dust collection groove 141 and slides in the dust collection groove 141. During the sliding process, the pin shaft 152 is always in contact with the bottom of the dust collection box 11 with the assistance of the spring 151 until the pin shaft 152 is released into the pin hole 1411 by the spring 151. At this time, the dust collection box 11 is installed in place in the dust collection groove 1411), so as to achieve the purpose of dust cleaning without overall disassembly of the catenary wear detection device 1 on the catenary. After the cleaning is completed, the catenary wear detection device 1 is used to detect the catenary to judge indicators such as the quality or life of the catenary.
[0044] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
