This utility model provides a suspension structure for a mining dump truck, including a suspension cylinder assembly disposed between the vehicle frame and the axle, and a pair of accumulators disposed on both sides of the frame. The suspension cylinder assembly includes a front axle cylinder disposed between the front axle and the frame, and at least two pairs of rear axle cylinders disposed between the rear axle and the frame. The number of rear axles corresponds to the number of rear axle cylinders. The rear axle cylinders and the accumulators disposed on the same side are connected to the oil chambers of the accumulators through accumulator valve blocks. The oil chambers of the accumulators on both sides are connected through hydraulic pipelines. This utility model achieves balance of cylinder extension and contraction on one side by setting accumulators that are only connected to the rear axle cylinders. By connecting the left and right accumulators, it maintains the balance of the frame under uneven loading conditions, avoiding the tilting of the truck body under uneven loading, reducing the probability of rollover accidents, and improving transportation safety.

This utility model discloses a wellhead crude oil heating and temperature control device for preventing freezing and condensation, specifically relating to the field of wellhead crude oil heating. It includes a base plate, a heating component fixedly connected to the middle of the upper part of the base plate, a filter component fixedly connected to the upper surface of the inner surface of the heating component, a stirring component rotatably connected to the lower side of the heating component, and a feed pipe fixedly connected to the upper end of the heating component. The heating component includes a double-layer heating tank fixedly connected to the upper part of the base plate. This utility model, through its designed heating component, can maintain a constant temperature for wellhead crude oil via the heating tank. Simultaneously, a guide plate controls the flow rate of the wellhead crude oil, preventing excessive flow rate from causing damage to the next stage component and delaying the residence time of the wellhead crude oil in the double-layer heating tank. This allows the crude oil to more fully absorb heat from the double-layer tank, improving heating uniformity and enhancing the antifreeze and anti-condensation effect.

The utility model relates to the technical field of transmitters, in particular to a high-precision pressure liquid level transmitter with a temperature adjusting function, which comprises an adjusting mechanism, a limiting mechanism is arranged on the bottom side of the adjusting mechanism, the adjusting mechanism comprises a connecting pipe, a baffle is arranged in the connecting pipe, and a temperature sensor is arranged on the baffle. According to the high-precision pressure liquid level transmitter with the temperature adjustment function, liquid flows into the connecting pipe, the multiple baffles are arranged in the connecting pipe, the heating pieces are arranged in the baffles, and therefore the temperature of the heating pieces is increased in the mode that the baffles are installed in a staggered mode, and the temperature of the liquid flows into the connecting pipe. The interlayer is arranged on the inner wall of the solution cavity, and cooling liquid is poured into the interlayer, so that heat of the liquid can be absorbed by the cooling liquid in the interlayer when the liquid passes through the solution cavity in summer, and the heat of the liquid can be absorbed by the cooling liquid in the interlayer; and the temperature of the liquid is regulated and controlled according to different seasons.
