[0016] Four telescopic rods 11 are fixedly installed on the upper surface of base 1, the top of telescopic rod 11 is fixedly connected with the bottom of box 2, bidirectional screw rod 12 is rotatably connected between the inner wall of both ends of base 1, the outer surface of bidirectional screw rod 12 is threadedly sleeved with two moving kits 13, the outer surface of both sides of moving kit 13 is rotatably connected with inclined connecting rod 14, one end of inclined connecting rod 14 is rotatably connected with the bottom of box 2, hand wheel 15 is rotatably connected with one side of base 1, one end of hand wheel 15 is fixedly connected with one end of bidirectional screw rod 12, and operator can drive bidirectional screw rod 12 to rotate by rotating hand wheel 15, and the two moving kits 13 are synchronously moved by the rotation of bidirectional screw rod 12 through the thread of both sides opposite direction, and four inclined connecting rods 14 are rotated to a certain extent by the movement of both sides moving kits 13, and the upward jacking force is exerted to the bottom of box 2 in the process of rotation, so that the lifting process of box 2 is realized, and the box 2 that is lifted facilitates better overhauling and maintenance for operator, when some parts of equipment need to be adjusted and observed, the height of protective cover can be flexibly adjusted, and the maintenance convenience is improved.

[0017] The length and width of the box body 2 are the same as the length and width of the top cover 21, the outer surface of the box body 2 is in sliding fit with the outer surface of the top cover 21, the U-shaped handle is fixedly installed at one end of the top cover 21, a plurality of ventilation grooves 20 are formed at both ends of the box body 2, the plurality of ventilation grooves 20 are distributed at equal intervals, the outer surface of the box body 2 is coated with an anti-corrosion coating, the box body 2 is made of aluminum alloy, the top cover 21 is kept in fit with one end of the box body 2 after being turned over by 90 degrees, the friction generated between the top cover 21 and the box body 2 during the turning over movement is reduced, the U-shaped handle is arranged on one side of the top cover 21, which is convenient for the operator to better push and turn over the top cover 21 by force on both sides, the plurality of ventilation grooves 20 are convenient for the oil machinery to better dissipate heat and ventilate, the anti-corrosion coating coated on the outer surface of the box body 2 is better to face complex weather environment and reduce damage to the protective cover, and the aluminum alloy material can increase the crashworthiness of the box body 2 and improve the protectiveness of the oil machinery.

[0018] The telescopic rods 11 are arranged in a rectangular array, the moving sleeves 13 and the tilt connecting rods 14 are arranged in mirror image, and the two moving sleeves 13 are threadedly sleeved on the two sides of the bidirectional threaded rod 12, respectively. The four telescopic rods 11 arranged in a rectangular array help the box body 2 to keep stable up-down movement in the lifting process, provide guidance and support for the lifting of the box body 2, and prevent the box body 2 from tilting and shaking during the lifting process. The moving sleeves 13 and the tilt connecting rods 14 arranged in mirror image are to make the moving distances of the two moving sleeves 13 the same, so that the same force is exerted on the box body 2 under the rotation of the two moving sleeves 13, and the balance of the force on both sides is ensured.

[0019] Working principle: when the protective cover needs to be opened, the operator pushes the top cover 21 to one side of the box body 2 through the U-shaped handle at one end of the top cover 21, so that the top cover 21 is turned over to one side of the box body 2. The top cover 21 rotates at a fixed radius during the turning over process, and the first connecting rod 26 connected at one end drives the top cover 21 to rotate. The first connecting rod 26 drives the third spring 27 to stretch to the other side during the rotation. At the same time, the sleeve 23 at one end of the top cover 21 rotates with the rotating shaft 24 during the turning over process, so that the sleeve 23 can slide linearly along the outer surface of the slide rail 22. When the top cover 21 is turned over by 90 degrees, the sleeve 23 is located at the uppermost part of the slide rail 22. When it needs to be reset, the operator pushes the top cover 21 in the opposite direction. The first connecting rod 26 is provided with power assistance for reverse rotation under the tightening force of the third spring 27, so that the sleeve 23 gradually slides along the outer surface of the slide rail 22 to the other side of the slide rail 22 during the rotation, thereby ensuring the stability of the movement of the top cover 21 and realizing the stable opening and closing of the protective cover.

[0020] When the box 2 needs to be lifted, the operator rotates the hand wheel 15 to drive the bidirectional threaded rod 12 to move horizontally, the rotating bidirectional threaded rod 12 drives the two moving sleeve kits 13 to move in opposite directions along the outer surface of the bidirectional threaded rod 12 through the threads in different directions on the two sides, the synchronous movement of the two moving sleeve kits 13 drives the four inclined connecting rods 14 to rotate, with the rotation of the inclined connecting rods 14, the other end of the inclined connecting rods 14 applies a jacking force to the bottom end of the box 2, the four telescopic rods 11 provide stable moving support for the jacking of the box 2, helping the box 2 to be more stable during the lifting process, and the box 2 is lowered from the bidirectional threaded rod 12 rotating in the opposite direction, thereby realizing the lifting movement of the box 2.
