Problems solved by technology

[0005] The embodiment of the present application provides a paver cold start device, which solves the problems in the prior art that the diesel machinery is difficult to start due to the waxing of diesel oil in a low temperature environment and is easy to stall during the start process, and avoids the problems in the prior art. The defect of the cold start device of the diesel paver realizes the small risk and low limit of the cold start device of the diesel paver and will not affect the engine

Embodiment 1

[0085] see figure 1 , is an isometric view of the heating module 100 of the paver cold start device of the present invention; the heating module 100 includes a primary heating device 120, a secondary heating device 130, a tertiary heating device 140, a heating module body 110, and a normal heating device 150 , the heat preservation device 160 and the heating module fixing device 170.

[0086] The heating module main body 110 includes a heating module tank body 111, a heating module main shaft 112, a shaft sealing device 113 and a power element 114; the heating module main body 110 plays a role of carrying the heating module 100, and the heating module The module tank body 111 is a cylindrical tank body capped up and down, and its top and bottom are respectively provided with a diesel oil inlet and a diesel oil outlet; the heating module main shaft 112 is rotatably and fixedly connected to the heating module tank body 111 , coaxial with the heating module tank body 111, and it...

Embodiment 2

[0098] Considering that the cold start of the paver engine not only has certain requirements on the fuel in the fuel system, but also has certain requirements on the water temperature of the engine circulating water in the cooling system, the temperature of the urea solution in the exhaust gas treatment system, and the temperature of the hydraulic oil in the hydraulic system. Requirements; the present invention has carried out the optimization and performance expansion of the cold start device on the basis of Embodiment 1, such as figure 2 As shown, the paver cold start arrangement also includes a tandem combination system 300 .

[0099] The structure of the series combination system 300 is as follows Figure 9 As shown, it includes a second spline sleeve 310, a shift fork 320, an electric actuator 330, and a bearing 340, and a spline sleeve is provided at the end of the heating module main shaft 112 away from the motor 114-1. The heating module main shaft 112 is fixedly con...

Abstract

The invention discloses a paver cold start device, and relates to the technical field of road construction machines. The paver cold start device comprises a heating module, an oil inlet and return system and a temperature detection device. The heating module comprises a first-stage heating device, a second-stage heating device, a third-stage heating device, a heating module body, a normal-state heating device, a heat preservation device and a heating module fixing device. Power of the heating module is from a motor. The oil inlet and return system achieves the functions that fuel oil is drawnout from a fuel oil tank and is heated by the heating module and then conveyed to an engine to allow the engine to run. The temperature detection device comprises a diesel oil temperature sensor arranged in a paver diesel and fuel oil tank and a circulating water temperature sensor arranged in the engine and achieves the functions of converting liquid temperature into signals and transmitting signals to a paver center control, and temperature parameters are provided for decision making of starting of heating circulation or normal-state circulation of the paver center control.

Description

technical field [0001] The invention relates to the technical field of road construction machinery, in particular to a cold start device for a paver. Background technique [0002] When the temperature of the environment where the diesel oil is located is lower than the wax precipitation point of the diesel oil, the diesel oil will precipitate solid paraffin crystals, resulting in waxing; the waxing of the diesel oil will cause the filter element of the diesel filter to block or block the oil pipeline, and then It brings problems such as insufficient oil supply, unstable ignition and even flameout to diesel-powered machinery; when wax formation is severe, there is a risk of diesel engine flameout suddenly even during the operation of the machine; this is necessary for continuous and uninterrupted operation As far as the paver is concerned, the waxing of diesel oil before starting the paver powered by diesel oil will affect the normal operation of the paving work and delay the...
