DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0019] This application provides a hydraulic station oil tank, such as... Figures 1 to 3 As shown, it includes: the main body of the fuel tank 1, the protective box 2, and the fixing mechanism 3.

[0020] The oil tank body 1 is rectangular in shape, with its top used to install hydraulic components; the protective box 2 is also rectangular in shape to fit the oil tank body 1, with an open top, and the oil tank body 1 is located inside the protective box 2. Figure 2 and Figure 3 As shown, the bottom surface of the protective box 2 is provided with four springs 21 of equal length that are naturally oriented towards the height of the protective box 2. The springs 21 are connected to the bottom of the oil tank body 1 and distributed at the four corners of the bottom of the oil tank body 1. Multiple buffer blocks 22 are provided on the inner wall of the protective box 2 and are respectively located at the four corners of the four outer walls of the oil tank body 1 and between the corresponding inner walls of the protective box 2. The bottom of the protective box 2 is provided with two connecting shafts 23 that are oriented towards the length of the protective box 2 and arranged in an array along the width direction. The connecting shafts 23 are rotatable around their own axis and have rollers 24 at both ends. The fixing mechanism 3 is provided at the bottom of the oil tank body 1 and is used to fix the oil tank body 1 and the protective box 2.

[0021] When installing the hydraulic station, the presence of the connecting shaft 23 and roller 24 allows the hydraulic station oil tank to be pushed to the predetermined installation position, simplifying the installation process and greatly improving the flexibility of the hydraulic station oil tank. At the same time, if the protective box 2 collides with the hydraulic oil tank during movement, the impact of the collision on the hydraulic oil tank can be effectively mitigated by the action of the spring 21 and the buffer block 22, thereby optimizing the protective function of the hydraulic station oil tank.

[0022] After the hydraulic station is installed, the oil tank body 1 and the protective box 2 are not completely fixed, which may cause the oil tank to vibrate during operation. At this time, the fixing mechanism 3 can fix the oil tank body 1 and the protective box 2, thereby effectively solving the problem of oil tank instability during operation of the hydraulic station and thus effectively improving the operating stability of the hydraulic station oil tank.

[0023] Specifically, such as Figures 2 to 4As shown, the bottom of the oil tank body 1 is provided with two matching grooves 11, the fixing mechanism 3 includes a top plate 31 which is parallelly arranged between the bottom of the oil tank body 1 and the bottom of the protection box 2 and is arranged to move along the height direction of the protection box 2, the two ends of the top plate 31 are provided with lock blocks 311 which are matched with the matching grooves 11, the top of the protection box 2 is provided with a pair of limiting rods 32 which are parallel to each other and are directed to the width direction of the protection box 2, the plane formed by the axes of the two limiting rods 32 is parallel to the bottom surface of the protection box 2, the fixing mechanism 3 further includes a mounting seat 33 which is arranged at the bottom of the protection box 2 and is arranged to move along the width direction of the protection box 2, the mounting seat 33 is provided with a pair of brake clamps 331 which are directed to the connecting shaft 23, the brake clamps 331 have a certain elastic deformation, and the distance between the ends of the two brake clamps 331 in the natural state is less than the shaft diameter of the connecting shaft 23. In application, when the hydraulic station oil tank is pushed to the predetermined installation position, the top plate 31 is lifted along the height direction of the protection box 2 and abuts against the bottom of the oil tank body 1, the lock blocks 311 on the top plate 31 enter the matching grooves 11 and push the oil tank body 1 upwards until the top end of the oil tank body 1 abuts against the limiting rods 32, at this time, the bottom of the oil tank body 1 is tightly pushed by the top plate 31, the top of the oil tank body 1 is limited by the limiting rods 32, and under the cooperation of the matching grooves 11 and the lock blocks 311, the degrees of freedom of the oil tank body 1 are all limited, that is, the oil tank body 1 is completely fixed; at the same time, the mounting seat 33 drives the brake clamps 331 to move towards one of the connecting shafts 23, so that the brake clamps 331 clamp the connecting shaft 23, thereby fixing the position of the protection box 2. Through the arrangement of the top plate 31, the limiting rods 32 and the brake clamps 331, and through the cooperation of the lock blocks 311 and the matching grooves 11, the oil tank body 1 can be effectively fixed, thereby effectively ensuring the stability of the operation of the hydraulic station oil tank.

[0024] As a preferred structure, as Figure 2 and Figure 3As shown, the bottom surface of the protection box 2 is provided with a door-shaped frame 34, the bottom of the top plate 31 is vertically provided with a top rod 35 penetrating the top of the door-shaped frame 34, the end of the top rod 35 is provided with a pulley 36, the rotation axis of which is arranged towards the length direction of the protection box 2, the bottom surface of the protection box 2 in the door-shaped frame 34 is provided with a matching block 37, one end of which is a slope arranged towards the pulley 36, the other end of the matching block 37 is connected with a push rod 38 arranged towards the width direction of the protection box 2 and penetrating the side of the door-shaped frame 34 and the side wall of the protection box 2, the end of the push rod 38 is provided with a lock hole 381 along the height direction of the protection box 2, one side of the protection box 2 is provided with a mounting block 25, a lock pin 251 is penetratingly arranged on the mounting block 25 and is arranged to move along the height direction of the protection box 2 and matches the lock hole 381. In application, the push rod 38 is pushed into the protection box 2 by using a linear mechanism with large pushing force, so that the slope of the matching block 37 matches the pulley 36, in the process of continuous pushing of the push rod 38, the pulley 36 rolls along the slope, and the matching block 37 lifts the top rod 35 along the axis thereof, so as to realize the lifting of the top plate 31, when the tank body 1 is tightly lifted to the limiting rod 32, the lock hole 381 on the push rod 38 also moves to the lower side of the lock pin 251, and the lock pin 251 is inserted into the lock hole 381, so as to fix the push rod 38, thereby realizing the fixation of the tank body 1. The advantages of arranging the pulley 36, the matching block 37 and the push rod 38 are that the lifting of the top rod 35 along the axis thereof can be realized in a smaller longitudinal space, so as to optimize the structure of the hydraulic station tank.

[0025] Specifically, as shown in Figure 2 and Figure 3 the bottom surface of the protection box 2 is provided with a strip-shaped hole 26 matched with the push rod 38, the push rod 38 is vertically provided with a vertical rod 39 matched in the strip-shaped hole 26, and the end of the vertical rod 39 is connected to the mounting seat 33. In application, when the push rod 38 is pushed into the protection box 2 and the top plate 31 is lifted, the push rod 38 simultaneously drives the brake clamp 331 on the mounting seat 33 to move towards the connecting shaft 23 through the vertical rod 39; when the top plate 31 tightly lifts the tank body 1 to the limiting rod 32, the brake clamp 331 also clamps the connecting shaft 23, so as to limit the rotation of the connecting shaft 23, thereby realizing the pushing of the push rod 38 and the fixation of the tank body 1 and the protection box 2 at the same time, and effectively improving the convenience of the installation of the hydraulic station tank.

[0026] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
