Description

Technical Field

[0001] The present invention relates to the field of petroleum exploration, and in particular to an omnidirectional runner structure. Background Art

[0002] Rope grooves are designed on the winch drum of an oil rig to prevent friction, deformation, and premature wear of the wire rope during loading. While there are many different types of rope grooves, the most widely used is the Libas grooved device. The wire rope is automatically arranged in the grooves based on the groove pattern and the winding dynamics, winding back and forth from left to right or right to left. During the lifting and lowering processes, the wire rope is driven by the load through the crown block and the runner assembly. The winding order of the wire rope on the drum is reversed: during lifting, the wire rope is retracted onto the drum, while during lowering, the wire rope is released and unwound from the drum. On its way from the drum to the crown block, the wire rope passes through a freely sliding runner. This runner is mounted on a sliding rod. The wire rope rotates the runner under tension. The runner grooves provide space for the wire rope to move, but also restrict its path, requiring it to remain within the runner grooves. However, in actual construction, the wire rope often jumps out of the runner groove and directly rubs against the slide bar. This situation is most common when there is a jump. If the wire rope jumps out of the slide, it must be manually reinstalled into the slide bar, otherwise it will affect the winding sequence of the wire rope on the drum. This situation is also common in other operations that require the winding and unwinding of wire ropes, and similar problems will be encountered in all of them.

[0003] In summary, the wire rope jumping out of the runner chute will affect the normal operation of the equipment and cause a series of other problems:

[0004] ⑴ The usual runner structure has no anti-slip function design and only serves as a channel for the wire rope to move;

[0005] ⑵ Ordinary wheels can only move in a straight line. If the wire rope vibrates and jumps, it cannot be limited by the wire rope.

[0006] ⑶ The single-channel wheel has a single function and cannot meet the needs of expanded applications;

[0007] (4) The wire rope jumps out of the pulley and needs to be manually returned to its original position, which affects the normal construction and reduces the working time;

[0008] ⑸ The wire rope jumping out of the sheave will cause other safety problems, which is not conducive to safe production;

[0009] (6) For comprehensive logging, the wire rope jumping out of the rotating wheel affects its orderly arrangement on the drum, which directly affects the accuracy of depth measurement;

[0010] ⑺There is no runner guide structure with composite functions, which cannot meet the needs of complex working conditions. Summary of the Invention

[0011] The present invention aims to solve the problems existing in the prior art and provides an omnidirectional rotating wheel structure.

[0012] The technical solution is as follows:

[0013] An omnidirectional rotating wheel structure comprises a rotating wheel, a rotating wheel frame and a base. The rotating wheel is arranged on the rotating wheel frame for transverse rotation, and the rotating wheel frame is arranged on the base through an elastic supporting member.

[0014] Furthermore, the elastic support member is a universal spring. The universal spring comprises a support spring and an inner ring. The inner ring comprises two upper and lower sleeves. The upper sleeve is fixed to the rotating wheel frame, while the lower sleeve is fixed to the base and coaxial with the upper sleeve. The ends of the support spring are rotatably mounted on the upper and lower sleeves. The ends of the upper and lower sleeves are provided with stoppers that engage with the support spring. The support spring is mounted on the exterior of the upper and lower sleeves. The stoppers are circular rings fixed to the ends of the upper and lower sleeves, with a diameter larger than the support spring. The universal spring also comprises an outer ring. The outer ring comprises two upper and lower outer sleeves. The upper and lower outer sleeves are detachably fixed to the rotating wheel frame and the base. The upper and lower outer sleeves are respectively mounted on the upper and lower sleeves, with the support spring interposed between the outer sleeves. A taper thread is provided circumferentially around the outer sleeve. The rotating wheel frame and the base are provided with thread holes corresponding to the positions of the taper thread.

[0015] Furthermore, the runner is a guide wheel with a circumferential guide groove. The runner is a guide wheel assembly composed of multiple parallel guide wheels arranged vertically. The runner frame is a U-shaped frame consisting of a cross brace, a vertical brace, and a bearing rod. The runner is rotatably mounted on the bearing rod via a bearing. The cross brace is elastically connected to the base via an elastic support member below.

[0016] The beneficial effects of the present invention are:

[0017] ⑴The all-round rotating guide wheel structure has an anti-slip function design. It is not only a channel for the wire rope to move, but also expands its application range;

[0018] (2) The runner structure not only supports the linear motion of the runner, but is also suitable for dynamically limiting the wire rope when it vibrates and jumps;

[0019] ⑶The wheel structure is perfect in function and can meet the needs of expansion applications in many aspects;

[0020] (4) The wheel structure can ensure that the wire rope cannot jump out of the wheel, maintaining normal construction and improving work efficiency;

[0021] 5. The sheave structure ensures that the wire rope cannot jump out of the sheave, thus avoiding the possibility of other safety problems and contributing to safe production;

[0022] (6) For comprehensive logging, the rotor structure ensures that the wire rope cannot jump out of the rotor, thus ensuring its orderly arrangement on the drum and ensuring the accuracy of depth measurement;

[0023] ⑺The rotating wheel structure has complex functions and can meet the needs of complex working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1:

[0030] An omnidirectional wheel structure includes a wheel, a wheel frame, and a base. The wheel is laterally rotatably arranged on the wheel frame. The wheel frame is arranged on the base through an elastic support member and is rotatably sleeved on the wheel shaft 18.

[0031] The rotating wheel is a guide group consisting of two parallel guide wheels with circumferential guide grooves, wherein two anti-slip grooves coaxial with the guide wheel are circumferentially provided near the end faces of the lower guide wheel, and the cross-section of the anti-slip groove is V-shaped or U-shaped. Two flanges with the same groove shape as the anti-slip groove are provided near the end faces of the upper guide wheel. The flanges can be embedded in the anti-slip grooves and cooperate with the gap of the anti-slip grooves to form a sliding rope way. When the two guide wheels rotate, the sliding rope way remains dynamically closed, thereby preventing the wire rope from slipping.

[0032] Example 2:

[0033] Based on an omnidirectional rotating wheel structure of the first embodiment, the elastic support member is a universal rotating spring. The universal rotating spring includes a support spring and a universal rotating spring inner ring; the universal rotating spring inner ring includes two upper and lower sleeves; the upper sleeve is fixed to the rotating wheel frame; the lower sleeve is fixed to the base and is coaxial with the upper sleeve; the two ends of the support spring are rotatably sleeved on the upper and lower sleeves respectively. The ends of the upper and lower sleeves are provided with limit members, and the limit members cooperate with the support spring to limit the position. The support spring is sleeved on the outside of the upper and lower sleeves, and the limit member is a circular ring fixed to the ends of the upper and lower sleeves, and the diameter of the circular ring is larger than the support spring. The universal rotating spring also includes a universal rotating spring outer ring, and the universal rotating spring outer ring includes two upper and lower outer sleeves. The upper and lower outer sleeves are detachably fixed to the rotating wheel frame and the base, and the upper and lower outer sleeves are sleeved on the upper and lower sleeves respectively, and the support spring is interposed between the outer sleeves. The outer sleeve is circumferentially provided with a taper tube; the rotating wheel frame and the base are provided with thread holes corresponding to the positions of the taper tube.

[0034] The wheel frame is a U-shaped frame consisting of a horizontal support, a vertical support and a bearing rod. The wheel is rotatably mounted on the bearing rod through a bearing; the bottom of the horizontal support is elastically connected to the base through an elastic support member.

[0035] Example 3:

[0036] See also Figure 1 , an omnidirectional wheel structure, the whole is made of hard steel, and consists of a base, cross braces, vertical braces, U-shaped wheels, universal springs, etc. The base supports the cross braces and vertical braces, and together with other structures, it realizes the omnidirectional rotation function.

[0037] 1. Base. The base supports the wheel structure and is constructed from a section of square steel, 200mm long, 100mm wide, and 50mm thick. A section of square steel is welded to each end of the base as a support step, 50mm long, 100mm wide, and 30mm thick. A 30mm diameter threaded hole is drilled through the center of the base and step. The base fixing screws are inserted through the holes to secure the base to another object. A universal spring is installed in the center of the base.

[0038] 2. Universal spring. The universal spring sits within the outer ring. (1) The inner and outer rings of the universal spring are a section of steel pipe measuring 100mm outer diameter, 70mm high, and 5mm thick. This serves as the spring's housing and consists of two sections: the upper section secured to the lower center of the cross brace, and the lower section secured to the center of the base. The spring is clamped between these two sections. The spring is wound through the inner ring using a spiral stutter. The inner ring of the universal spring is a steel ring with an outer diameter of 100mm, an inner diameter of 70mm, and a thickness of 5mm, welded flush to the top of the pipe to prevent the spring from falling out. The inner and outer rings are secured to corresponding holes in the base and cross brace via taper pipes welded to either side of the outer ring. (2) Taper pipes. The taper tube is a steel tube with an outer diameter of 30mm, a height of 40mm, and a wall thickness of 5mm. It has internal threads and is welded to both sides of the outer ring wall of the universal spring. Corresponding threaded holes are turned on the base and cross brace of the corresponding taper tube, and the fixing screws are screwed to fix the taper tube.

[0039] 3. Cross brace. The base and cross brace are connected dynamically in all directions through a universal spring. The cross brace is a square steel bar with a length of 130mm, a width of 80mm, and a thickness of 50mm. There are 10mm diameter holes on both sides of the cross brace for connecting the vertical braces on both sides with the cross brace fixing screws.

[0040] 4. Vertical supports. The vertical supports are made of square steel, 130mm long, 50mm wide, and 50mm thick. 10mm diameter holes are drilled on each side of the vertical supports, corresponding to the cross supports, for connecting the ends of the cross supports with cross support screws. 10mm diameter holes are drilled in the upper portion of each vertical support, allowing the vertical support screws to secure the bearing rods. (1) Connecting rod. The connecting rod is made of square steel, 110mm long, 50mm wide, and 50mm thick. It connects the two U-shaped wheels. 10mm diameter holes are drilled in the rotating shafts of the two U-shaped wheels. Connecting rod screws connect the connecting rod to the two U-shaped wheels through the corresponding holes on each side of the connecting rod. A nested bearing is located in the middle of each connecting rod, fixed to the vertical supports by the bearing rods. (2) Bearing rod. The bearing rod has a cylindrical front end and a section of square steel at the rear end. The front end is connected to the fixed bearing, and the rear end is connected to the vertical supports with the vertical support screws. The horizontal support, the vertical support and the connecting rod are connected and fixed to each other through screws and the rotating shaft of the U-shaped wheel, providing an all-round rotation space for the sleeve rotation of the U-shaped wheel.

[0041] 5. U-shaped wheels. Two U-shaped wheels are connected, with the interlocking flanges and recesses of the upper and lower U-shaped wheels nested together to form a rope slide in the middle. No matter how the wire rope rotates, it is controlled by the interlocking limit and does not fall off the rope slide.

[0042] The omnidirectional rotating wheel structure, driven by a universal spring, allows 360° rotation. Dynamic azimuth adjustment is also achieved through the spring's elasticity. A restraining structure composed of horizontal and vertical supports and bearing rods creates a seamless, smooth passageway. The wire rope is restrained and prevented from disengaging in any direction within the ropeway. The entire structure can be disassembled into separate units for easy maintenance and assembly.
