Fig. 1 is a schematic structural view of the cable auxiliary fixing device in this embodiment. Fig. 2 is a schematic structural view of the fixing clip in this embodiment. Referring to fig. 1 and 2, the auxiliary cable fixing device includes a steel wire rope 1 and a plurality of fixing fixtures 2 disposed on the steel wire rope 1 at intervals, a limiting ring 3 is disposed on the steel wire rope 1 below the fixing fixtures 2, and the upper end of the limiting ring 3 supports the fixing fixtures 2 to prevent the fixing fixtures 2 from sliding downward. The fixing clamp 2 comprises two clamping plates 21 which are arranged oppositely, each clamping plate 21 is provided with a first clamping part 22 and a second clamping part 23 which protrude outwards, and the two clamping plates 21 are fixedly connected together by fasteners 24 arranged on the two clamping plates 21. The first clamping parts 22 on the two clamping plates 21 are oppositely arranged to form a clamping space for accommodating the steel wire rope 1; the second clamping portions 22 of the two clamping plates 21 are also oppositely arranged to form a clamping space for accommodating the cable 4.
In the practical application process, the limiting ring 3 is fixedly arranged on the steel wire rope 1, the first clamping part 22 of the fixing clamp 2 is sleeved above the limiting ring 3 on the steel wire rope 1, the fixing clamp 2 is supported by the limiting ring 3, and at the moment, the fixing clamp 2 can rotate around the steel wire rope 1 under the action of external force. The cable 4 is inserted into the second clamping portion 23, and the second clamping portion 23 is used to fixedly clamp the cable 4. The cable 4 can be lowered to the preset height in the vertical shaft by lowering the steel wire rope 1.
Specifically speaking, mounting fixture 2 rotates to be connected on wire rope 1, and in order to make it more convenient to rotate, the department of being connected of wire rope 1 and mounting fixture 2 coats and is coated with lubricating oil, for example the butter, can be comparatively laborsaving when rotating mounting fixture 2.
In this embodiment, the first clamping portions 22 are semicircular, and the diameter of the first clamping portions 22 is slightly larger than that of the steel wire rope 1, so that after a clamping space formed by two opposite first clamping portions 22 is sleeved on the steel wire rope 1, the first clamping portions can smoothly slide and rotate on the steel wire rope 1, and the cable 4 can be conveniently fixed subsequently. The second clamping portion 23 is also formed in a semicircular shape to facilitate stable clamping of the cable 4. The diameter of the second clamping portion 23 should be similar to the diameter of the cable 4, so that the cable is not easy to clamp when the diameter of the second clamping portion is too small, and the cable shakes in the second clamping portion 23 when the diameter of the second clamping portion is too large.
In addition, since the second clamping portion 23 is generally made of a hard material, in order to prevent the cable 4 from being worn, a protective sleeve is further provided in the second clamping portion 23, and for example, a flexible material such as a rubber pad is adhered to the inner wall of the second clamping portion 23, so that the cable 4 can be prevented from sliding and the outer skin of the cable 4 can be protected from being worn.
In addition, as shown in fig. 1, in this embodiment, the limiting ring 3 is a wire rope chuck, which is a common product in the market, has low cost, and can be fixedly connected to the wire rope 1, thereby supporting the fixing clamp 2. In addition, because the upper end face of the steel wire rope clamping head is not a plane, the fixing clamp 2 is easy to clamp when rotating, a gasket 5 is arranged between the limiting ring 3 and the fixing clamp 2, and the gasket 5 is sleeved on the steel wire rope 1. As shown in fig. 1, the spacer 5 has an annular structure, a lower end abutting against the limiting ring 3, and an upper end forming an annular plane capable of supporting the fixing clamp 2. Since the fixing clip 2 is supported on an annular plane, the fixing clip 2 can smoothly rotate around the wire rope 1.
When setting up spacing ring 3, in order to make mounting fixture 2 arrange ground more evenly, it is more stable when transferring the cable, with each spacing ring 3 equidistant setting, correspondingly, each mounting fixture 2 also equidistant setting is on wire rope 1. In one embodiment, the distance between each spacing ring 3 and each fixing clamp 2 is set to be 10 meters, so that the cable can be stressed uniformly, the underground cable can be stabilized, and the cable can be prevented from shaking left and right to touch the well wall.
In addition, the embodiment also provides a construction method of the cable in the shaft, which is used for lowering the cable into the shaft and fixing the cable on a cable hook in the shaft, and the cable auxiliary fixing device is adopted in the construction process. The construction method of the cable in the vertical shaft comprises the following steps:
and step S1, manufacturing the fixing clamp, and installing the steel wire rope and the cable.
Firstly, a plurality of fixing clamps are manufactured for clamping the cable and the steel wire rope, so that the cable can be synchronously placed in the vertical shaft along with the steel wire rope. Then, a wire rope suspension point is provided above the shaft for suspending the wire rope, for example, a stabilizing vehicle is provided above the shaft, and a suspension point for lowering the wire rope is provided on the stabilizing vehicle, and the wire rope is lowered into the shaft through the suspension point. Then, a plurality of gaskets are sleeved on the steel wire rope, a limiting ring is arranged at the end part of the steel wire rope, a fixing clamp is arranged on the steel wire rope above the limiting ring, and the end part of the cable is arranged in the fixing clamp. It should be noted that a spacer as described above is required between the stop collar and the mounting fixture.
The cable is fixed in the second clamping part of the fixing clamp in a penetrating way. Specifically, set up the protective sheath in the second clamping part, later wear to establish the cable in the second clamping part, make the protective sheath parcel in the periphery of cable, closely the centre gripping of cable between two clamping pieces through the fastener at last for the cable can remove along with mounting fixture.
In addition, the steel wire rope is arranged in the first clamping part of the fixing clamp in a penetrating mode, and the diameter of the first clamping part is larger than that of the steel wire rope, so that the fixing clamp can rotate around the steel wire rope. In order to make the rotation of the fixing clamp smoother, lubricating oil needs to be applied to the position where the fixing clamp is installed on the steel wire rope.
It should be noted that the suspension point needs to be set as follows: the vertical distance between the suspension point and the inner wall of the shaft is not less than the sum of the lengths of the fixing clamp and the cable hook in the shaft. Therefore, after the cable is lowered into the shaft, the cable can be ensured not to collide with the shaft inner wall and the cable hook.
And step S2, lowering the cable.
As shown in fig. 3, firstly, the end of the fixing clamp provided with the cable is placed at one side close to the center of the shaft, the end of the fixing clamp provided with the steel wire rope is placed at one side close to the inner wall of the shaft, and the cable is placed at a constant speed. And then, installing a limiting ring on the steel wire rope at preset intervals, such as 10 meters, and connecting the cable and the steel wire rope together by using the fixing clamp until the preset height is reached. When the cable is placed, the cable is far away from the inner wall of the vertical shaft, and the cable can be prevented from colliding with the inner wall of the vertical shaft and the cable hook.
It should be noted that a gasket is arranged between each limit ring and the fixing clamp. When the fixing clamp rotates subsequently, the gasket can support the fixing clamp, and the fixing clamp is prevented from being clamped by the limiting ring.
And step S3, fixing the cable.
As shown in fig. 4, first, the end of the fixing jig where the cable is provided is pushed to rotate the cable around the wire rope, and finally the cable is brought close to the cable hook on the inner wall of the shaft. Then, the fixing clamps are sequentially disassembled from top to bottom, and the cables in the clamps are moved into the cable hooks for fixing.
When the cable in the shaft is lowered and fixed by adopting the traditional method, if the cable is closer to the inner wall of the shaft, the cable is easy to touch the inner wall of the shaft and a cable hook to cause cable abrasion; if the cable is far away from the inner wall of the vertical shaft, the problem of abrasion can be avoided, but when the cable is fixed into the cable hook, the cable can be moved only by large external force, and workers working high above the ground are difficult to apply force, so that the cable is difficult to fix, and the construction process is dangerous. The cable construction method can solve the problem. When the cable is discharged downwards, the steel wire rope is close to the wall of the vertical shaft well, the cable is far away from the wall of the vertical shaft well, and the cable cannot collide with the inner wall of the vertical shaft well and the cable hook under the condition that the upper end of the steel wire rope is fixed. When fixing the cable, promote the one end that is equipped with the cable of mounting fixture, the cable can rotate around wire rope this moment, and then be close to the cable hook, because the distance of cable and cable hook is nearer, the construction workman exerts less external force and can remove the cable to the cable hook in to it is fixed with the cable.
The cable auxiliary fixing device and the method for constructing a cable in a shaft are further described by specific examples.
First, describing the fixing jig 2 in detail, as shown in fig. 2, the clamping plate 21 of the fixing jig 2 is made of flat steel having a thickness of 6mm and a width of 60mm, and is provided with a first clamping portion 22 and a second clamping portion 23 protruding outward from left to right, respectively, and bolt holes for installing the fasteners 24 are provided at both ends and the middle of the clamping plate 21. The first clamping portion 22 is used for clamping the steel wire rope 1, and the second clamping portion 23 is used for clamping the cable. In this example, the fastener 24 is a bolt and nut, and two clamp plates 21 can be detachably connected together through the bolt and nut, so that the cable and the steel wire rope can be conveniently installed in the fixing clamp.
Specifically, in this example, the diameter of the steel cord 1 is 24mm, and the diameter of the cable 4 is 60 mm; accordingly, the diameter of the first clamping portion 22 is 30mm, and the diameter of the second clamping portion 23 is 60 mm. When the fixing clamp 2 is installed on the steel wire rope 1, the fixing clamp can rotate around the steel wire rope 1. The second clamping portion 23 can then firmly clamp the cable in the middle of the clamping plate. The bolt model is phi 14, and three bolts are arranged on each fixing clamp 2.
The gasket 5 is made of flat steel with the thickness of 10mm, a round hole with the diameter of 25mm is formed in the middle of the gasket, and the steel wire rope 1 penetrates through the round hole.
When the cable is constructed in the vertical shaft, the method comprises the following steps:
firstly, a stable vehicle is arranged above the vertical shaft, a steel wire rope 1 is wound on the stable vehicle, and the front end of the steel wire rope 1 extends into the vertical shaft after passing through a steel wire rope suspension point. A plurality of gaskets 5 are sleeved on a steel wire rope 1, then a steel wire rope clamping head is arranged at the front end of the steel wire rope 1, the downward movement of the gaskets 5 is limited, one gasket 5 is arranged above the steel wire rope clamping head, and then a fixing clamp 2 is arranged. The first clamping part 22 is installed on the steel wire rope 1, the second clamping part 23 is installed on the cable 4, and the two clamping plates 21 are fastened together through bolts, so that the cable 4 and the steel wire rope 1 can be synchronously lowered into a vertical shaft.
It is to be noted that the vertical distance of the suspension point from the shaft inner wall 6 is not less than the sum of the lengths of the fixing clamp 2 and the cable hook 7 in the shaft. Thus, after lowering the cable 4 into the shaft, it is ensured that the cable 4 does not collide with the shaft inner wall 6 and the cable hook 7.
And then, beginning to lower the steel wire rope 1 and the cable 4, installing a steel wire rope clamping head on the steel wire rope 1 every time the steel wire rope 1 and the cable 4 are lowered by 10 meters, moving a gasket 5 to the steel wire rope clamping head, installing the fixing clamp 2, and connecting the cable 4 and the steel wire rope 1 to the fixing clamp 2. When the elevator is placed downwards, one end, provided with the cable 4, of the fixing clamp 2 is placed on one side close to the center of the shaft, and one end, provided with the steel wire rope 1, of the fixing clamp 2 is placed on one side close to the inner wall 6 of the shaft. And stopping lowering the cable 4 and the steel wire rope 1 until the cable 4 reaches a preset position in the shaft.
And finally, pushing one end of the fixing clamp 2, which is provided with the cable 4, to enable the cable 4 to rotate around the steel wire rope 1, enabling the cable 4 to rotate from the side far away from the inner wall 6 of the shaft to the side close to the inner wall 6 of the shaft at the moment, and finally enabling the cable 4 to be close to the cable hook 7 of the inner wall 6 of the shaft. Then, the fixing jig 2 is detached from the top down in order, and the cable 4 in the fixing jig 2 is moved into the cable hook 7 to be fixed.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
