The invention will be described in detail below with reference to the accompanying drawings in conjunction with exemplary embodiments.

Fig. 1 is a schematic view of a hydraulic oil tank according to an embodiment of the present invention. As shown in fig. 1, the utility model provides a hydraulic oil tank, hydraulic oil tank includes oil tank body 10, and oil tank body 10's horizontal side is formed with from the inside sunken pipeline mounting groove 20 of lateral wall and is equipped with the pipeline joint 11 that is located pipeline mounting groove 20, and oil tank body 10's vertical side is formed with from the inside sunken tire of lateral wall and dodges groove 30.

Specifically, this hydraulic tank's oil tank body 10 is the special-shaped structure form, includes pipeline mounting groove 20 and tire particularly and dodges groove 30, is located under the condition of frame one side at hydraulic tank, is formed into for oil pipe dismouting space in the pipeline mounting groove 20, and the staff of being convenient for carries out the dismouting on pipeline joint 11, and the tire dodges and forms to dodge the space for the tire in groove 30 simultaneously, avoids interfering. Therefore, the oil tank body 10 is designed to be of a special-shaped structure, so that interference is avoided, convenience in disassembly and assembly is guaranteed, after-sale maintenance is facilitated, and the volume of the inner cavity of the oil tank body 10 is prevented from being too small.

The "inside-outside" relationship between the respective components of the hydraulic tank is determined based on the center of the tank body 10.

Fig. 2 is a front view of the hydraulic oil tank of fig. 1. Fig. 3 is a plan view of the hydraulic oil tank of fig. 1. As shown in fig. 2 and 3, a partition 12 is disposed in the oil tank body 10 to divide the inner cavity of the oil tank body 10 into an oil suction chamber 13 and an oil return chamber 14 which are communicated with each other, the pipeline joint 11 includes an oil suction pipe joint 111 communicated with the oil suction chamber 13 and an oil return pipe joint 112 communicated with the oil return chamber 14, and the volume of the oil return chamber 14 is greater than the volume of the oil suction chamber 13.

As will be understood by those skilled in the art, the hydraulic oil tank is connected to the hydraulic actuators through oil pipes and forms a hydraulic circuit, and thus, an oil suction pipe for supplying oil to the hydraulic actuators and an oil return pipe for returning oil from the hydraulic actuators are connected to the hydraulic oil tank. The oil suction pipe is connected with the oil suction pipe joint 111 to suck oil from the oil suction chamber 13, the oil return pipe is connected with the oil return pipe joint 112 to return hydraulic oil to the oil return chamber 14, and the hydraulic oil in the oil return chamber 14 can flow into the oil suction chamber 13, so that a circulating hydraulic circuit is formed.

As can be understood by those skilled in the art, the hydraulic oil flows back into the oil return cavity 14 after being worked by the hydraulic actuator, so that the temperature of the hydraulic oil in the oil return cavity 14 is high, and the volume of the oil return cavity 14 is larger than that of the oil suction cavity 13, which is convenient for heat dissipation. Therefore, the partition 12 is arranged to separate the inner cavity of the oil tank body 10 into hot and cold, the oil return cavity 14 is used for containing hot oil, and the oil suction cavity 13 is used for containing cold oil flowing from the oil return cavity 14 after heat dissipation.

As shown in fig. 3, in the illustrated embodiment, the lateral side wall of the tank body 10 includes an inner concave wall section and an outer folded transition wall section, and the inner concave wall section and the outer folded wall section are connected to form the conduit installation groove 20. The oil suction pipe joint 111 is arranged on the inner concave wall section, and the oil return pipe joint 112 is arranged on the outer folding transition wall section.

The outer shape of the tank body 10 is not limited to the illustrated embodiment, and may be adaptively adjusted according to the installation environment. For example, in another alternative embodiment, the pipeline installation groove 20 is a U-shaped groove, that is, the two ends of the inner concave wall section are connected with the outward-folded transitional wall section to form the U-shaped groove.

It should be noted that the inner cavity of the oil tank body 10 is not filled with hydraulic oil, and the liquid level of the hydraulic oil in the inner cavity generally does not exceed three-fourths of the height of the oil tank body 10. Therefore, the oil return pipe joint 112 is disposed close to the top wall of the tank body 10, so that the liquid level of the hydraulic oil is prevented from exceeding the height of the oil return pipe joint 112, and thus the formation of back pressure at the oil return pipe joint 112 is prevented.

In addition, hydraulic oil is led into the oil return cavity 14 through the oil return inner tube 15 after passing through the oil return pipe joint 112, and the oil outlet end of the oil return inner tube 15 is close to the bottom wall of the oil tank body 10, so that the liquid level of the hydraulic oil exceeds the oil outlet end of the oil return inner tube 15, and the hydraulic oil is prevented from being dissolved into air due to splashing when flowing back to the oil return cavity 14.

It will be appreciated that, in order to facilitate oil suction, the oil suction pipe joint 111 is provided close to the bottom wall of the tank body 10.

In a preferred embodiment, the bulkhead 12 is longitudinally disposed and includes an exposed folded-over transition wall section and a bulkhead section located within the internal cavity of the tank body 10. In other words, the folded-out transition wall section is a part of the lateral side wall of the tank body 10 and also a part of the bulkhead 12, and in this embodiment, the bulkhead section and the folded-out transition wall section are a single plate. Of course, in another alternative embodiment, the partition 12 comprises only partition segments, and only the partition segments need to be located in the inner cavity of the tank body 10, and the installation position has more flexibility.

The utility model discloses an in the embodiment, be equipped with a plurality of interval arrangements's through-hole 121 in order to communicate oil absorption chamber 13 and oil return chamber 14 on the baffle 12, the vertical interval of any one in a plurality of through-holes 121 and baffle 12's diapire is not less than 5mm, and baffle 12's diapire meets with the diapire of oil tank body 10.

It should be noted that impurities inevitably exist in each component element in the whole hydraulic circuit, and hydraulic oil passes through the circuit, carries the impurities and flows into the oil return chamber 14, and the impurities in the hydraulic oil generally sink to the bottom. In order to prevent impurities in the hydraulic oil from flowing into the oil suction chamber 13, that is, the vertical distance between the through hole 121 located at the lowest position and the bottom wall of the partition plate 12 is not less than 5mm, preferably, the vertical distance between any one of the through holes 121 and the bottom wall of the partition plate 12 is not less than 10mm.

It should be noted that the through holes 121 include, for example, rectangular through holes, circular through holes, kidney-shaped through holes, etc., the distance between the through holes 121 and the bottom wall of the partition board 12 refers to the vertical distance between the bottom ends of the through holes 121 and the bottom wall of the partition board 12, and taking the through holes 121 as the rectangular through holes as an example, the vertical distance between the through holes 121 and the bottom wall of the partition board 12 is the distance between the bottom inner walls of the rectangular through holes and the bottom wall of the partition board 12.
