Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a cleaning device for a sliding contact line. Background Technology

[0002] The grab bucket crane plays a crucial role in the material handling and distribution process. The sliding contact line is the power source for the grab bucket crane. Currently, there are various types of sliding contact lines available in China, including safety sliding contact lines, rigid sliding contact lines, and seamless multi-stage sliding contact lines. Our company uses rigid sliding contact lines, which offer advantages such as reliable operation, suitability for harsh environments, high mechanical strength, large current carrying capacity, reduced energy loss, diverse wiring options, large heat dissipation area, simple structure, and convenient installation and maintenance. However, a major disadvantage is its susceptibility to rust. Rust not only affects the appearance of the sliding contact line but, more importantly, it impacts its performance and safety. Rust can reduce the conductivity of the sliding contact line, increasing resistance and thus affecting the efficiency and stability of power transmission. Furthermore, rust can cause poor contact between the sliding contact line and the equipment, leading to unstable operation or malfunctions. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cleaning device for sliding contact lines, which facilitates the cleaning and rust removal of sliding contact lines and improves the service life of sliding contact lines.

[0004] The technical solution of this utility model is as follows: a cleaning device for a sliding contact line, which is set on both sides of the current collector on the traveling contact line, including a fixed base and a cleaning assembly set on the fixed base. The fixed base is provided with a receiving cavity. The cleaning assembly includes a spring seat placed in the receiving cavity, a spring member set on the spring seat, a brush seat set at the bottom of the spring seat, and a rust-removing wire brush set at the bottom of the brush seat. The spring seat is slidably disposed in the receiving cavity. The spring member is sleeved on the spring seat. The top end of the spring member contacts the inner wall of the receiving cavity. The bottom of the rust-removing wire brush contacts the traveling contact line.

[0005] As can be seen from the above scheme, the spring seat is used to maintain the pressure of the rust-removing wire brush. The use of a wire brush to remove rust increases the friction of the contact surface, thereby achieving better removal of rust from the surface of the crane sliding line. This utility model allows the rust-removing wire brush to sweep away rust and dust on the sliding contact line while sliding with the current collector slider. This utility model uses the elasticity of the spring to compress the rust-removing wire brush against the surface of the crane sliding line. The rust-removing wire brush and the crane sliding line form a certain compressive resistance. When the grab crane is running, the contact and friction between the rust-removing wire brush and the crane track achieve a good cleaning effect. When the current collector slider passes by, there is better contact and power reception.

[0006] A mounting bracket is provided between the two sets of fixed seats. The mounting bracket has a movable slide groove, and the end of each fixed seat has a waist-shaped adjustment groove. A locking pin is inserted into the waist-shaped adjustment groove, and the locking pin extends out of the movable slide groove and is fixedly connected by fasteners. Therefore, the mounting bracket uses the movable slide groove to limit the movement of the fixed seat, facilitating the adaptation to current collectors of different sizes.

[0007] An insulating pad is attached to the top of the spring seat. Therefore, the insulating pad is used for insulation.

[0008] The mounting bracket is connected to the current collector via a diagonal brace module. The diagonal brace module includes a fixed diagonal brace, a fixed bracket, and an insulating porcelain insulator. The fixed diagonal brace includes two sets of diagonal brace rods connected by buffer springs. One side of the fixed diagonal brace is connected to the mounting bracket, and the other side is connected to the current collector via the fixed bracket. The insulating porcelain insulator is connected to the fixed bracket. Therefore, the fixed bracket and the fixed diagonal brace are used to connect the fixed base to the current collector; the buffer springs are used to cushion the movement of the fixed base, reducing the impact force during operation; and the insulating porcelain insulator is used for insulation.

[0009] The fixed bracket includes a bracket mounting component and a frame plate that slides on the bracket mounting component. The frame plate is connected to the fixed diagonal brace, and the bracket mounting component is connected to the current collector. The bracket mounting component is provided with a slot that matches the frame plate, and the frame plate is provided with an installation adjustment hole. After the bracket mounting component corresponds to the installation adjustment hole, a fastening plug is inserted.

[0010] The spring seat includes an integrally formed connecting portion, a limiting portion, and a sliding portion disposed between the connecting portion and the limiting portion. The spring member is sleeved on the limiting portion, and the spring seat slides in conjunction with the receiving cavity through the sliding portion. Therefore, the limiting portion facilitates the limiting of the spring member, preventing the spring from tilting under pressure.

[0011] The bottom of the spring seat is provided with a locking block, and the top of the brush holder is provided with a sliding groove that matches the locking block. Therefore, the brush holder facilitates the disassembly and replacement of the rust-removing wire brush through the sliding engagement of the locking block and the sliding groove.
