Description

Technical Field

[0001] This utility model relates to the technical field of overhead contact line operation vehicle slewing platform, and in particular to the brake spring and pressure testing and adjustment instrument for overhead contact line operation vehicle slewing platform. Background Technology

[0002] The rotating working platform of the overhead contact line maintenance vehicle is a specialized piece of equipment used for the inspection and maintenance of overhead contact lines. Its main function is to provide maintenance personnel with a lifting and rotating working platform, thereby enabling efficient and flexible maintenance operations on the overhead contact lines. To ensure the stability and safety of this type of working platform during operation, the pressure monitoring and regulation of the hydraulic system is particularly crucial. Therefore, developing a pressure testing and adjustment device for this system is of great significance.

[0003] In existing technologies, pressure testing instruments used on overhead contact line maintenance vehicle slewing platforms are mostly fixed installations, typically mounted directly on the platform itself. This presents challenges such as inconvenience in disassembly and transport, and limitations in application scenarios, making it difficult to meet the needs for flexible on-site debugging, maintenance, and repair. Especially in areas involving sensor calibration, abnormal pressure identification, and hydraulic dynamic response optimization, traditional equipment struggles to achieve rapid adaptation. To address these shortcomings, we have introduced a brake spring-loaded pressure testing and adjustment instrument for overhead contact line maintenance vehicle slewing platforms. Utility Model Content

[0004] This utility model discloses a brake spring and pressure testing and adjustment instrument for the slewing platform of a catenary work vehicle, aiming to solve the technical problem that most of the pressure gauges used in related technologies are directly fixed on the slewing platform, which is inconvenient to disassemble and carry, and therefore inconvenient to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The contact wire maintenance vehicle's slewing platform brake spring and pressure testing and adjustment instrument includes a toolbox, a pressure gauge, a first sleeve, a second sleeve, a bearing ring, and a fixing bolt. The toolbox has a cover connected to one side of its top via a hinge. A mounting pad is placed at the bottom of the toolbox. The pressure gauge, first sleeve, second sleeve, bearing ring, and fixing bolt are placed on top of the mounting pad inside the toolbox. A nut is threaded to the outer side of the threaded end of the fixing bolt, and a threaded groove is formed at the end of the fixing bolt away from the nut.

[0007] In use, by setting up a pressure gauge, a first sleeve, a second sleeve, a bearing ring, and a fixing bolt, the threaded groove on one side of the fixing bolt is fixed to the screw on the rotating working platform of the overhead contact line vehicle. Depending on the usage requirements, the first or second sleeve is passed through the fixing bolt, and then the pressure gauge and bearing ring are passed through the fixing bolt and tightened with a nut. The installation is quick and convenient, and the use is easy. This solves the technical problem in related technologies where the pressure gauges are mostly directly fixed to the rotating working platform, making them inconvenient to disassemble and carry, and causing inconvenience in use.

[0008] In a preferred embodiment, the top of the mounting pad has a first slot, a second slot, a third slot, a fourth slot, and a fifth slot, and the pressure gauge, the first sleeve, the second sleeve, the bearing ring, and the fixing bolt are placed inside the first slot, the second slot, the third slot, the fourth slot, and the fifth slot in sequence.

[0009] By placing the pressure gauge, sleeve 1, sleeve 2, bearing ring, and fixing bolt sequentially inside slots 1, 2, 3, 4, and 5, it is convenient to secure and carry the pressure gauge, sleeve 1, sleeve 2, bearing ring, and fixing bolt.

[0010] In a preferred embodiment, a groove is provided inside the top of the box lid, and a handle is rotatably connected inside the groove. A latch is provided on the side of the box lid and toolbox that is close to each other and away from the hinge.

[0011] The device is easy to lift and carry by the handle inside the groove.

[0012] In a preferred embodiment, the length of the first sleeve is shorter than the length of the second sleeve.

[0013] By setting up No. 1 and No. 2 bushings, it is convenient to adjust the use of No. 1 and No. 2 bushings according to the needs of use.

[0014] In a preferred embodiment, the mounting pad is made of sponge.

[0015] By using sponge as the material for the mounting pad, it is beneficial to protect the pressure gauge, No. 1 sleeve, No. 2 sleeve, bearing ring, and fixing bolt.

[0016] The contact wire maintenance vehicle slewing platform brake spring and pressure testing and adjustment instrument provided by this utility model has the following advantages compared with the prior art:

[0017] 1. In use, by setting up a pressure gauge, No. 1 sleeve, No. 2 sleeve, bearing ring and fixing bolt, fix the threaded groove on one side of the fixing bolt to the screw on the rotating working platform of the contact wire operation vehicle, and pass the No. 1 sleeve or No. 2 sleeve through the fixing bolt according to the usage requirements, then pass the pressure gauge and bearing ring through the fixing bolt, and tighten them with nuts. The installation is quick and convenient and easy to use.

[0018] 2. This utility model effectively solves the technical problems of pressure gauges being directly fixed on rotary work platforms in the prior art, which are inconvenient to disassemble and carry, and are not flexible in use, thus improving the adaptability and convenience of the device.
