Description

A material hoisting device for deep wells Technical Field

[0001] This utility model relates to the field of deep well material lifting technology, and more specifically, to a material lifting device for deep wells. Background Technology

[0002] Currently, material lifting processes are required during deep well construction operations (feeding materials down into the well or transferring materials up and out). The on-site lifting equipment uses scaffolding to erect chain hoists. Chain hoists are heavy, making installation laborious. Furthermore, if the chain breaks, replacement requires disassembling the entire transmission mechanism, resulting in lengthy repair times. Additionally, the humid environment underground accelerates chain corrosion, reducing the critical fracture load by 15%-20%. In summary, chain hoists suffer from drawbacks such as heavy weight (inconvenient installation), long repair times after damage (cannot be partially repaired), and poor environmental adaptability. Therefore, the material lifting process in deep wells needs improvement. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art and to propose a material lifting device for deep wells.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A material hoisting device for deep wells includes a support plate, connecting rollers, anti-detachment hooks, nuts, mounting components, pulleys, corrosion-resistant synthetic fiber ropes, U-shaped steel plates, through holes, fixing bolts, traction ropes, and ring buckles.

[0006] The connecting roller is fixedly connected to two opposing support plates;

[0007] The end of the anti-detachment hook is provided with an external thread. The end of the anti-detachment hook passes through the connecting roller and is threaded with a nut that contacts the connecting roller. The anti-detachment hook is connected to a lifting ring that is located above the wellhead of the deep well and is fixed in position.

[0008] The pulley is mounted between two support plates via a mounting assembly, and the pulley is rotatably connected to the mounting assembly.

[0009] A corrosion-resistant synthetic fiber rope is wound around a pulley, with one end of the rope connected to the material to be lifted and the other end connected to the force-applying end.

[0010] The U-shaped steel plate is welded to the ends of the two support plates;

[0011] Two fixing bolts pass through the through holes opened on the bottom surface of the U-shaped steel plate and are threaded into the U-shaped steel plate;

[0012] The end of the traction rope is connected to a ring buckle that mates with the fixing bolt, and the other end of the traction rope is connected to the force application end.

[0013] Furthermore, the mounting assembly includes a pivot and fastening bolts.

[0014] The support plate has a circular perforation that allows the pivot to pass through from one side;

[0015] The rotating shaft passes through a perforation and is mounted on the support plate by fastening bolts, and a pulley located between the two support plates is rotatably connected to the rotating shaft.

[0016] Furthermore, the support plate is made of flat steel and has a convex buffer portion formed in the middle.

[0017] Furthermore, the connecting roller is connected to the support plate via a fixing pin.

[0018] Furthermore, the lifting ring is fixed on a tripod, which is fixed on the ground on one side of the wellhead.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This application provides a simple and feasible solution for lifting and lowering deep well materials. It has the advantages of small size and light weight. Even if damage occurs, only local maintenance is required, without disassembling the entire lifting device. This significantly reduces maintenance time compared to chain hoists. At the same time, the corrosion-resistant synthetic fiber rope has a strength reduction of only 5% under the same wet conditions in the well, thus significantly extending its service life. The safety and operability of the material lifting process in the well can meet the needs of on-site installation. As a result, the lifting and lowering process of deep well materials is optimized and the effect is better. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0026] As shown in Figures 1 and 2, a material lifting device for deep wells includes a support plate 1, a connecting roller 2, an anti-detachment hook 3, a nut 4, an installation assembly 5, a pulley 6, a corrosion-resistant synthetic fiber rope (not shown in the figures), a U-shaped steel plate 7, a through hole (not shown in the figures), a fixing bolt 8, a traction rope, and a ring buckle.

[0027] The connecting roller 2 is fixedly connected to two opposing support plates 1 (specifically, the support plates 1 are made of flat steel and the connecting roller 2 is connected to the support plates 1 by fixing pins, which are not labeled in the figure).

[0028] The end of the anti-detachment hook 3 is provided with an external thread. The end of the anti-detachment hook 3 passes through the connecting roller 2 and is threaded with a nut 4 that contacts the connecting roller 2. The anti-detachment hook 3 is connected to a lifting ring that is located above the wellhead of the deep well and is fixed in position.

[0029] The pulley 6 is mounted between the two support plates 1 via the mounting assembly 5, and the pulley 6 is rotatably connected to the mounting assembly 5;

[0030] A corrosion-resistant synthetic fiber rope is wound around pulley 6, with one end of the rope connected to the material to be lifted and the other end connected to the force-applying end (the corrosion-resistant synthetic fiber rope is not shown in the figure).

[0031] The U-shaped steel plate 7 is welded to the ends of the two support plates 1;

[0032] Two fixing bolts 8 pass through the through holes opened on the bottom surface of the U-shaped steel plate 7 and are threaded to the U-shaped steel plate 7;

[0033] The end of the traction rope is connected to a ring buckle that mates with the fixing bolt 8, and the other end of the traction rope is connected to the force-applying end (neither the traction rope nor the ring buckle is shown in the figure, wherein the ring buckle is fitted onto the fixing bolt).

[0034] As shown in Figure 1, the specific implementation of this utility model embodiment includes a rotating shaft 51 and fastening bolts 52.

[0035] The support plate 1 has a circular through hole (the through hole is not numbered in the figure) that allows the rotating shaft 51 to pass through from one side;

[0036] The rotating shaft 51 passes through the through hole and is mounted on the support plate 1 by fastening bolt 52, and a pulley 6 located between the two support plates 1 is rotatably connected to the rotating shaft 51.

[0037] In order to buffer the material during lifting or lowering and thus reduce the problem of excessive stress on the connecting surface of the support plate 1, the above embodiment is further optimized by forming an outwardly protruding buffer portion 101 in the middle of the support plate 1.

[0038] In a further refinement of the embodiment of this utility model, the lifting ring is fixed on a tripod, and the tripod is fixed on the ground on one side of the wellhead (the tripod is not shown in the figure).

[0039] The working process of this utility model:

[0040] Based on the above problems, the anti-detachment hook 3 is first selected to connect the lifting ring to prevent the hook from detaching from the lifting ring when the material in the well is lifted to the vicinity of the deep well opening and the traction rope is pulled. The anti-detachment hook 3 cooperates with the lifting ring fixed on the tripod on one side of the deep well opening. The bottom of the anti-detachment hook 3 passes through the connecting roller 2 and is locked in position by the nut 4, without affecting the normal rotation of the anti-detachment hook 3. The two ends of the connecting roller 2 are fixed to the support plate 1 by pins.

[0041] Secondly, the support plate 1 is made of flat steel and has an outward protrusion structure in the middle, which plays a buffering role during the lifting or lowering of objects and reduces the problem of excessive force on the connecting surfaces of the support plate 1.

[0042] Furthermore, the pulley 6 adopts a grooved structure to facilitate the winding of the corrosion-resistant synthetic fiber rope. At the same time, the pulley 6 is configured on the rotating shaft 51, which passes through the support plate 1 and is fixed in position by fastening bolts 52, thereby ensuring that the pulley 6 will not move horizontally during operation. One end of the corrosion-resistant synthetic fiber rope is connected to the material to be lifted, and the other end of the corrosion-resistant synthetic fiber rope is used for manual lifting or lowering of the material. During the material lifting process, the pulley 6 can save effort.

[0043] Finally, the traction rope auxiliary fixing structure is made of steel plate and pressed into a U-shape and welded to the support plate 1. Bolts are drilled symmetrically on both sides of the bottom of the U-shaped steel plate 7 to facilitate the installation of fixing bolts 8. After the fixing bolts 8 are installed, the ring buckle at the end of the traction rope is put on the two fixing bolts 8 to connect the traction rope to the device. The other end of the traction rope is always held by the staff. When the material is lifted to the vicinity of the wellhead, the traction rope is pulled to move the material away from the top of the wellhead, which facilitates manual unloading. At the same time, when it is necessary to transport materials down into the well, the staff can also connect the anti-corrosion synthetic fiber rope to the material at a position away from the wellhead through the traction rope, thereby improving the safety of unloading and loading.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
