Description

Technical Field

[0001] The present invention relates to the technical field of skid base equipment, and in particular to a skid base stable structure that facilitates the lifting of a skid base. Background Art

[0002] Skid-mounted equipment is usually a form of combination of equipment frames and the overall equipment. It refers to a group of equipment fixed on a chassis and can be used after being moved. There is no need to install valves and instruments in the middle, and it can be used directly by connecting pipelines. In the field of petroleum equipment manufacturing and design, skid bases are often selected as the installation basis for equipment. The existing skid base has a frame structure, and four lifting lugs or lifting rods are symmetrically welded and suspended on both sides;

[0003] However, when this traditional skid base adopts this structural form, since the main stress points are located at the welding positions of the lifting lugs or lifting rods during the lifting of the skid base, the lifting lugs or lifting rods often deform and fall off during the lifting process due to the overweight of the lifting equipment; there are relatively large potential safety hazards;

[0004] On the other hand, when the lifting lugs or lifting rods are suspended, it is necessary to narrow the skid base, which affects the equipment layout on the skid base; when the skid base is narrowed, it will also cause the equipment to have relatively poor lateral stability during the overall lifting process, and there are potential safety hazards of flipping, swinging, and tilting.

[0005] Therefore, there is an urgent need for a skid base stable structure that facilitates the lifting of a skid base to solve the above problems. Summary of the Invention

[0006] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments.

[0013] The lifting ring mechanism is engaged with one end of the main lifting rope far from the main lifting ear and one end of the auxiliary lifting rope far from the auxiliary lifting ear.

[0014] As a preferred solution of the stable structure of the pry base during hoisting according to the present invention, wherein: the lifting ring mechanism includes a first connecting ring and a second connecting ring.

[0015] Wherein, the first connecting ring is engaged with the annular groove, the second connecting ring is engaged with the corresponding main lifting rope or auxiliary lifting rope, and the number of the lifting ring mechanisms is four groups.

[0016] As a preferred solution of the stable structure of the pry base during hoisting according to the present invention, wherein: through grooves are symmetrically provided on both sides of the bottom frame, and the through grooves are used to accommodate the boom mechanism. A damping pad is fixedly connected to the inner wall of the through groove, and a notch is reserved on one side of the through groove, and the width of the notch is smaller than the radius of the boom main body.

[0017] As a preferred solution of the stable structure of the pry base during hoisting according to the present invention, wherein: protective cover plates for shielding the auxiliary lifting ears are symmetrically rotatably connected to both sides of the bottom frame.

[0019] As a preferred solution of the stable structure of the pry base during hoisting according to the present invention, wherein: the inner support frame includes a plurality of transverse H-shaped steels fixedly connected to the inner side of the bottom frame and a plurality of longitudinal H-shaped steels fixedly connected to the inner side of the bottom frame.

The external hoisting of the boom mechanism is convenient for timely replacement.

[0025] 3. After hoisting, by removing the boom mechanism and allowing the boom main body to completely pass through the through slot, once the boom main body has been bent and deformed during passing, it cannot be completely received into the through slot, thus completing the self-inspection work.

By rotating the adjusting bolt to drive the limiting block to move towards the outside of the notch groove, the rotation of the protective cover plate is restricted, greatly improving the overall portability.

[0038] Embodiment 1

[0039] Refer to Figures 1-5, which is the first embodiment of the present invention, provides a stable structure for the pry base during hoisting, including a main body mechanism 100, a suspension rod mechanism 200, a suspension rope mechanism 300, and a suspension ring mechanism 400.

[0040] Among them, the main body mechanism 100 includes a bottom frame 101, an inner support frame 102 arranged inside the bottom frame 101, and main lifting lugs 103 symmetrically arranged on both sides of the bottom frame 101. The inner support frame 102 includes a plurality of transverse H-shaped steels fixedly connected to the inner side of the bottom frame 101, and a plurality of longitudinal H-shaped steels fixedly connected to the inner side of the bottom frame 101. The transverse H-shaped steels and the longitudinal H-shaped steels are arranged in a crosswise manner, increasing the overall structural stability of the base. On both sides of the bottom frame 101, storage grooves 101a are symmetrically opened. A plurality of auxiliary lifting lugs 105 are fixedly connected at equal intervals in the storage grooves 101a. On both sides of the bottom frame 101, protective cover plates 104 for shielding the auxiliary lifting lugs 105 are symmetrically rotatably connected. A plurality of strip-shaped grooves 104a are opened at equal intervals on the protective cover plates 104. The number of strip-shaped grooves 104a corresponds to the auxiliary suspension ropes 302 on the same side one by one. Through the influence of the strip-shaped grooves 104a, the use influence on the auxiliary suspension ropes 302 can be eliminated, and the auxiliary suspension ropes 302 can be prevented from being squeezed by the protective cover plates 104. The protective cover plates 104 are of L-shaped structure, and the length of the protective cover plates 104 is the same as the length of the storage grooves 101a. After the protective cover plates 104 are flipped and covered, the storage grooves 101a can be completely shielded, providing a concealed protective shield.

[0041] Further, a notch groove 101c is opened on one side of the bottom frame 101, and a limit block 107 is slidably connected in the notch groove 101c. One end of the limit block 107 is rotatably connected with an adjusting bolt 108. The adjusting bolt 108 is in threaded cooperation with the bottom frame 101 and fixedly connected with a rotating handle through the end penetrating the bottom frame 101. The limit block 107 can be pushed out of the notch groove 101c as the adjusting bolt 108 rotates, which can block the rotation of the protective cover plate 104 after being closed, compared with the locking pin structure.

[0042] The suspension rod mechanism 200 includes a suspension rod main body 201. A plurality of annular grooves 202 are symmetrically opened on the suspension rod main body 201. Straight grooves 203 are also symmetrically opened at both ends of the suspension rod main body 201. Cross bars 204 are fixedly connected in the straight grooves 203. On both sides of the bottom frame 101, through grooves 101b are symmetrically opened, and the through grooves 101b are used for storing the suspension rod mechanism 200. A damping pad 106 is fixedly connected to the inner wall of the through groove 101b. A notch is reserved on one side of the through groove 101b, and the width of the notch is smaller than the radius of the suspension rod main body 201. The suspension rod main body 201 can be inserted into the through groove 101b for self-inspection to observe whether it is deformed, and the damping pad 106 increases the contact friction force with it to ensure that it is not easy to slip off after being stored. The notch is provided for convenient removal.

[0043] The suspension rope mechanism 300 includes multiple strands of main suspension ropes 301 and auxiliary suspension ropes 302. The number of main suspension ropes 301 is equal to that of the main lifting lugs 103 and they are connected in one-to-one correspondence and cooperation. The number of auxiliary suspension ropes 302 is equal to that of the auxiliary lifting lugs 105 and they are connected in one-to-one correspondence and cooperation. Both the main suspension ropes 301 and the auxiliary suspension ropes 302 are stainless steel metal wire ropes. The main suspension ropes 301 and the main lifting lugs 103 are connected by hooks, which is convenient for the removal and storage of the main suspension ropes 301.

[0044] The lifting ring mechanism 400 cooperates with the ends of the main suspension ropes 301 far from the main lifting lugs 103 and the ends of the auxiliary suspension ropes 302 far from the auxiliary lifting lugs 105. Specifically, the lifting ring mechanism 400 includes a first connecting ring 401 and a second connecting ring 402. The diameter of the first connecting ring 401 is larger than that of the second connecting ring 402, and the first connecting ring 401 and the second connecting ring 402 are integrally formed. Among them, the first connecting ring 401 cooperates with the annular groove 202, and the second connecting ring 402 is connected to the corresponding main suspension rope 301 or auxiliary suspension rope 302. The number of the lifting ring mechanisms 400 is four groups. The cooperative setting of the multiple strands of main suspension ropes 301 and auxiliary suspension ropes 302 with the lifting lugs can hoist the pry base in all directions and avoid tilting during hoisting.

[0045] During the use process, first connect the different second connecting rings 402 with the corresponding main suspension ropes 301 and auxiliary suspension ropes 302, and then, through the symmetrically distributed main lifting lugs 103 and multiple laterally distributed auxiliary lifting lugs 105 at equal intervals, connect and cooperate with the other ends of the main suspension ropes 301 and auxiliary suspension ropes 302 during hoisting, which can disperse the gravity of the bottom frame 101 during the overall hoisting and ensure the stability during hoisting. And pass a boom main body 201 through each lifting ring mechanism 400 in turn, so that it is engaged with the corresponding annular groove 202 to avoid slipping during hoisting. When hoisting, only need to pass the rope of the hoisting machine through the straight slot 203 and connect it with the cross bar member 204 to complete the lifting. Through the external hoisting of the boom mechanism 200, it is convenient for timely replacement. After the hoisting is completed, by removing the boom mechanism 200, let the boom main body 201 completely pass through the through slot 101b. When passing through, once the boom main body 201 has been bent and deformed, it cannot be completely received into the through slot 101b, thus completing the self-inspection work. At this time, a new boom mechanism 200 needs to be replaced to facilitate the subsequent hoisting safety. And when the suspension rope mechanism 300 and the lifting ring mechanism 400 are not in use, they can be stored in the gap of the storage groove 101a, and turn the protective cover plate 104 downwards. Drive the limiting block 107 to move towards the outside of the notch groove 101c by rotating the adjusting bolt 108, thereby restricting the rotation of the protective cover plate 104, which greatly improves the overall portability.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
