摘要： Insulating means to be used with a screed for a road finishing machine comprises at least one insulating element and one connection element for a releasable connection with the screed. The insulating element is designed to cause, in a state of the insulating means connected with the screed, a reduced emission of heat from the screed through the insulating element.

摘要： A method may include determining, by a controller of a paving machine, to start a test of one or more heaters associated with a screed assembly of the paving machine. The method may further include sending, by the controller and to a tester device associated with the paving machine, one or more signals configured to cause a test voltage to be generated while the one or more heaters are sequentially turned off and then on during the test. The method may further include receiving, by the controller, a measurement of an insulation resistance of each of the one or more heaters during the test. The method may further include performing, by the controller, one or more actions based on a result of processing the measurement.

摘要： A screed assembly for an asphalt paving machine includes a lower screed plate, an upper screed plate and a heating element that is in contact with the lower screed plate. The screed assembly also includes a compression bolt assembly having a primary bolt, a compression bolt and a compression spring. The primary bolt has a through hole, and the compression bolt is adapted to be inserted through the hole of the primary bolt. The compression spring is adapted to be placed over the lower end of the primary bolt, so that the compression bolt assembly may cooperate with the upper screed plate to apply a compression force to the heating element on the lower screed plate.

摘要： A system and a method for monitoring a condition of a paving machine. The system includes a screed plate and a heating element for heating the screed plate. The system also includes a controller configured to determine a heat-up time for the screed plate and compare the heat-up time to a predetermined time. The controller is further configured to provide a signal indicating that the screed plate needs to be replaced if the heat-up time is less than or equal to the predetermined time.

摘要： A screed assembly for a paving machine includes a main screed unit having a first section and a second section. A hinge assembly located above the main screed unit pivotally couples the first section with the second section. The first section and the second section rotate around a horizontal axis passing through the hinge assembly. A seal member located between the hinge assembly and the main screed unit covers a gap defined between the first section and the second section below the hinge assembly such that the seal member covers the gap and laterally extends beyond the gap above the first section and the second section. A pair of heating components attached to the first section and the second section heats the first section and the second section.

摘要： A screed assembly includes a screed assembly frame and a screed plate removably connected to the screed assembly frame to define a space between the screed assembly frame and the screed plate. A heating element and a hold down device for securing the heating element can be provided in the space between the screed assembly frame and the screed plate. The heating element is configured to be removed from the space by sliding the heating element out of the space and disengaging the heating element from the hold down device without removing the screed plate from the screed assembly frame.

摘要： A fault detection system for a machine having a plurality of electrical conducting elements insulated from a frame ground of the machine is disclosed. The fault detection system may include a high voltage DC power source, a positive high voltage bus connected to a positive terminal of the high voltage DC power source and providing high voltage electrical power to the plurality of electrical conducting elements, and a negative high voltage bus connected to a negative terminal of the high voltage DC power source and returning high voltage electrical power from the plurality of electrical conducting elements. At least one of the positive and negative high voltage buses may be selectively connected through a plurality of switches to plural zones of the electrical conducting elements, with each of the plural zones being electrically connected in parallel, and selectively connected to the high voltage DC power source by one of the plurality of switches. A low voltage DC power source may be configured to form part of a leakage current detector selectively connected through each of the plurality of switches to each of the plural zones for detecting leakage current between an electrical conducting element and the frame ground.
