Description

Apparatus for preventing the movement of cable

The device that the cable in the pipeline of the present invention relates to prevent to be laid in moves, particularly relate to the cable that is embedded in order to prevent to be laid in the underground pipeline, because the factor of external environment condition, promptly, because passing through of vehicle and the actuating force that applies to specific direction constantly, and prevent the device that cable moves to what some directions moved.

The phenomenon that cable moves in pipeline, normally pass to and go in the underground piping to take place because of the vibrations that vehicle produced, it is not owing to have very big strength to pass to cable quickly, but because travelling of vehicle continuously passed to pipeline to the body power that is applied, and caused moving of the pipeline inner cable that is laid in.This be because, the position that is embedded on the one hand underground pipeline is kept and is immobilized, and on the ground of buried pipeline, form specific fare on the road of vehicle ', so the direction of the vehicle that travels on the ground on pipeline is only towards some certain directions.

Like this, because the direction of the vehicle that travels on the ground above the pipeline is always successively towards some directions, so though the power that each car is applied on the underground piping is very little, through a segment length time, when this strength is put aside, will demonstrate very large strength.Because big like this strength, the result causes cable to move, and at this moment, it is generally acknowledged that the power that is applied to usually on the cable has several tons so big.

Therefore, the locomotivity that is applied on the cable is not the privileged site that is limited only within cable, owing to produce this strength, it has the characteristic that is applied to equably on the cable total length, thereby cable is done as a whole alongst mobile together.

In order to prevent moving of this cable, in the prior art, be that the entrance point setting at pipeline prevents the device that cable moves, with preventing that cable is drawn into the phenomenon in the pipeline, attempt to prevent moving of pipeline.

, this solution of the prior art is though cable has been fixed on entrance point, but because the locomotivity of remainder can produce excessive pulling force at fixed position, and, in order to obtain satisfied fixed effect, must keep sizable bed knife at fixed position.When fixed position applies excessive pulling force to cable, be arranged on the lead of cable inside because be the thinner lead of diameter, it is big that the possibility of broken string just becomes, and this be in the process of cabling the fatal defective that must avoid.In addition, if cable is applied very big bed knife, because this bed knife also plays a part to hinder the principal element of cable normal function, so can not obtain the effect of cabling at the fixed position of cable.

The present invention finds out in order to solve above-mentioned the problems of the prior art, it just can prevent moving of cable with smaller strength, when from the moving direction of cable, it can be arranged on the outlet side of pipeline, so that on cable, do not produce pulling force longitudinally, but produce pressure longitudinally.In addition, the present invention also provides the fixture that can regulate fixed intervals, when with the diameter of convenient cable difference being arranged, also can obtain good fixed effect.

As mentioned above, in order to reach purpose of the present invention, in a kind of mode of the present invention, a kind of device that prevents that cable from moving is provided, this device is made of following each parts: by CONTACT WITH FRICTION the fixing means to prevent cable and pipeline from relatively moving strong with respect to inner surface of pipeline; Transport the parts that transport of said fixing means; When said fixing parts subtend side opposite when the diametric(al) of cable moves, guide the guiding parts of this mobile status; The above-mentioned parts that transport are applied along the pressure of pipe diameter direction, and can freely regulated extruder member, so that the said fixing parts are fixed up with respect to side opposite; Between above-mentioned can freely regulated extruder member and be placed between the cable in the pipeline so that make the extruding force of above-mentioned extruder member be applied to support unit on the above-mentioned cable equably.The above-mentioned device that prevents that cable from moving is made the shape that can insert validly between cable and the pipeline, makes its structure all very convenient for installation work and detached job.

According to a kind of specific mode of the present invention, above-mentionedly can constitute by following various parts by freely regulated extruder member: many cross link parts; Be arranged on the crossover sites of these cross link parts, wherein have at least one to have in inside along the extruder member gliding member of screw longitudinally; And run through above-mentioned these gliding members, along the adjusting parts of the longitudinal extension of above-mentioned extruder member,, make the longitudinal length of above-mentioned extruder member flexible by means of this rotation of regulating parts, change its length, thereby can apply extruding force transporting parts along the cable size direction.

What constitute in this way prevents cable moving device, does not have pulling force and pressure is arranged at the fixed position of cable, and by means of regulating extruder member changeably, it can be used for the different various cables of diameter.These characteristics of the present invention are to have utilized the motion of transporting parts and extruder member, make that be arranged on the fixed part that transports on the parts is fixed up with respect to side opposite and obtains.

Below, the suitable embodiment that present invention will be described in detail with reference to the accompanying.In the accompanying drawing:

Fig. 1 represents to be contained in the stereogram of the state on the cable according to the cable moving device that prevents of embodiments of the invention;

Fig. 2 is that plug-in type prevents that the device that cable moves from decomposing the stereogram that comes among Fig. 1;

Fig. 3 is that the plug-in type shown in Fig. 1 prevents that device that cable moves is arranged on the sectional drawing of the state in the pipeline;

Fig. 4 is that expression plug-in type of the present invention prevents the skiagraph that the structure of the device extruder member that cable moves has been amplified.

Fig. 1 is the stereogram that device (9) that expression adopts plug-in type according to the embodiment of the invention to prevent that cable from moving is fixed on cable (8) state in the pipeline (10), as shown in Figure 1, be fixed on cable (8) in the pipeline (10) and be enclosed in support unit (7) lining of cable, remain on and transport on the relatively-stationary position of guide plate (1) of fixed part (5).In the present embodiment, fixed part (5) is made of conical shape, when applying extruding force by means of the said cross link parts in back, it is just invaded in the pipeline (10), makes the whole device (9) that prevents that cable from moving not move with respect to pipeline (10).

Though among the illustrated embodiment of this specification, fixed part (5) is conical, but, as long as it can prevent pipeline (10) when going and prevent relatively moving between the device (9) that cable moves in inserting pipeline, it can make shape arbitrarily, for example also can make the annular to a lateral bending song.As shown in the figure, owing on guide plate (1), be provided with the gathering sill (3) that fixed part (5) can protrude, so fixed part (5) can advance or retreats by guide plate (1).

Fig. 2 is the stereogram that the decomposition that prevents the device (9) that cable moves shown in Fig. 1 is come.From Fig. 2, can at length recognize, fixed part (5) be positioned at transport parts (4) above, action by means of extruder member (6), along with transporting moving of parts (4), it just is fixed on the inner surface of pipeline (10) by the upper surface that passes on the guide plate (1) at the last formed gathering sill (3) of guide plate (1).As shown in the figure, extruder member (6) is arranged in cable support (7) and transports parts; (4) between, when resembling the back when regulating with the adjusting parts said, the inner surface of pipeline (10) is lived in gathering sill (3) extruding that makes fixed part (5) pass guide plate (1).

Because the shape of cable support (7) is made the shape that encases cable (8), therefore just become the pressure that is applied to equably on the cable (8) by extruder member (6) applied force, can not produce any injurious effects being arranged in the inner lead of cable (8).; because the most advanced and sophisticated area of fixed part (5) is compared very little with the contact area of cable support (7) and cable; so; even the pressure that acts at last on the cable (8) is very slight; but be applied to power on the fixed part (5) by transporting parts (4), but on fixed part (5), acted on and to make it be pressed into the pressure of the inner surface certain depth of pipeline (10).

The reason that cable support (7) is set is, because in normal circumstances, make with more crisp metal mostly on the surface of cable (8), when cable (8) is squeezed the compression of parts (6), the danger that sustains damage arranged.Please see Figure 2, the represented lining (2) of label (2) inserts in the flange section (12) of guide plate (1) end, has the function of the end of reinforcement guide plate (1).In the present embodiment, lining (2) is except the function that resembles top said end with reinforcement guide plate (1), the structure that also has the space between sealing guide plate (1) and the cable support (7) has the function that can prevent that foreign matter intrusion extruder member (6) the inside from going.

Fig. 3 is that expression prevents that device (9) that cable moves is arranged on the skiagraph of the state in the pipeline (10).As seen from the figure, usually, pipeline (10) is fixedly installed in the big module component of concrete (11).As said in the general introduction of this specification, the place of concrete component (11) is set, underground at road normally, the vehicle that travels on the ground is used in continuous masterpiece on pipeline (10) and the cable (8) by concrete component (11).Like this, said as the front, on cable (8), applied a kind of strength, cable (8) is continuously moved to some directions.

As shown in Figure 3, the length of fixed part (5) is bigger than the thickness of guide plate (1), if extruder member (6) is shunk fully, then fixed part (5) just passes the outer surface of guide plate (1), and the inner surface that faces toward pipeline (10) pushes.In the present embodiment, because the shape of fixed part (5) is conical, when extruder member (6) shrank, fixed part (5) was just invaded the inner surface of pipeline (10) to a certain extent, plays the effect that makes frictional force become very big.

Fig. 4 is the sectional drawing of amplification of representing the structure of extruder member (6) in detail.As seen from the figure, extruder member (6) is made up of many forficiform cross link parts (13) that are coupled to.One end of these cross link parts (13), respectively with gliding member (6d, 6g, 6f, 6e) in one be connected, its other end then with upper and lower joint component (6b, 6c) in one be connected.Therefore, these cross link parts just constitute the scissors that run through whole parts respectively and seal link between gliding member (6d, 6g, 6f, 6e) and top, bottom joint component (6b, 6c).As seen from the figure, upper joints parts (6b) contact with the bottom surface of transporting parts (4), and bottom joint component (6c) then contacts with the upper surface of cable support (7).Make and transport parts (4), undertaken by top, bottom joint component (6b, 6c) towards the direction extruding of leaving cable support (7).

Therefore, joint component (6b, 6c) is the most handy has the material of certain rigidity to make.As shown in the figure, connecting an end of above-mentioned cross link parts (13) on gliding member (6d, 6g, 6e, 6f), the adjusting rod (14) that extends along the length direction of extruder member (6) passes these gliding members.On the total length of adjusting rod (14) or specific part, make screw thread, and on whole gliding members (6d, 6g, 6f, 6e), perhaps be arranged at least on the gliding member (6d, 6e) at two ends, make the screw that can cooperate with adjusting rod, like this, by means of rotary regulating lever (14), gliding member is gone up at adjusting rod (14) moved, thereby regulate the flexible of extruder member (6).

Promptly, for example, when the outboard end that is rotatably provided in adjusting rod (14) to some directions, be that cable (8) exposes the handle (6a) on the direction of pipeline (10) outside, gliding member (6d, 6e) is gone up to shown in the figure at adjusting rod (14), when approaching direction moved mutually, cross link parts (13) just moved towards the direction of drawing in, and upper and lower joint component (6b, 6c) is moved up and down.Just move up so transport parts (4), make that be arranged in its lip-deep fixed part (5) passes guide plate (1), be fixed up with respect to the inner surface of pipeline (10).Can on all gliding members (6d, 6e, 6f, 6g), all make the screw of going up formed threaded engagement with adjusting rod (14) and come, also can be as above said, on the gliding member at two ends, make screw.Top, bottom joint component (6b, 6c) preferably have greasy property to a certain degree, so that can successfully move on the inner surface that transport parts (4) and on the outer surface of cable support (7).

Below, the operating position that prevents the device (9) that cable moves that has the embodiment of said structure according to the present invention is described.At first, cable support (7) is arranged in an end of cable (8), then, on it, puts extruder member (6).Again transport parts (4) be arranged in extruder member (6) upper joints parts (6b) above, put guide plate (1) then, and the position of the fixed part (5) on making it and transporting parts (4) overlaps.At this moment, regulate the folded state of extruder member (6), make fixed part (5) not protrude from the surface of guide plate (1).Preventing of assembling the in this way device (9) that cable moves after the inside of pipeline (10) moves to suitable position, rotate the handle (6a) of the adjusting rod (14) of extruder member (6) again, the cross link parts (13) of extruder member (6) are moved to the direction of mutual gathering, just make progress so transport parts (4), i.e. side shifting outside cable (8) diametric.

Since such moving, fixed part (5) just with suitable pressure fixing on the inner surface of pipeline (10), be able to fully to prevent that at cable (8) it from after the alongst mobile state, stopping the adjusting of adjusting rod in pipeline (10).When being fixed on cable (8) in the pipeline (10) in this way, even it is said as the front, because of travelling of vehicle applied actuating force on cable (8), but because the device (9) that cable moves that prevents on the port of export can prevent this moving, so just can integrally keep the position of cable (8) in pipeline (10).Though the both sides in the relative direction of the diameter of cable (8) among Fig. 2 all are provided with the device (9) that prevents cable and move, but also can be on some directions with wedge-shaped member or packing material as preventing device that cable moves position with the decision cable, and only on another direction, adopt according to the device (9) that prevents that cable from moving of the present invention.

Because the present invention is preventing that device (9) that cable moves is arranged on the end of the direction that cable (8) pulls out from pipeline (10), the front end of cable (8) is fixed, so it is different with prior art, what apply on cable (8) is not pulling force, but pressure, like this, compare, reduced to be arranged in the possibility of the wire fracture in the cable (8) greatly with prior art.But, can certainly be not preventing that the device that cable moves (9) is arranged on the front end of cable (8), and be arranged on the rear end, promptly cable (8) is drawn in the end of going in the pipeline (10).In addition,,, make its variation, so when the diameter of cable (8) changes, also can keep its stationary state effectively owing to can regulate to the folded state of extruder member (6) according to the device that prevents that cable from moving of the present invention.

Above with reference to description of drawings optimal embodiment of the present invention; but; in not exceeding by claims institute restricted portion, the technical staff of the technical field of the invention also should belong to protection scope of the present invention to improvement and variation that the present invention did.
