Description
The present invention is about a kind of construction method and a kind of cable-laying gear of cabling, especially about a kind of construction method and a kind of cable-laying gear that cable is laid along the cable laying route in a structure.
Usually, boiler room in the cogeneration power plant or similar facilities require the power room on ground and be installed in control board on the boiler room or electricapparatus and device between connect many distribution cables.For being laid in, constructs distribution cable in the distribution pipeline in the boiler room, adopted two kinds of methods: a kind of method is that a cable hank that is wound with distribution cable is risen on the boiler room, and the end with distribution cable send down from the open top end of distribution pipeline then; Another kind method is that an end of distribution cable is injected the distribution pipeline from distribution duct bottom openend, draws up then.
As disclosed in the day disclosure special permission communique Hei 7-123554, known have a kind of method, this method in a looped wire being placed into the distribution pipeline after, one end of one distribution cable is connected on this looped wire, and the shuttling movement by this lead is with the distribution cable distribution catheter interior that is laid in then.
Yet because above-mentioned boiler room height can reach tens of meters high, the length overall of distribution cable is also often above 100 meters.Nature, the very heavy (400kg～2000kg) of the cable hank weight that is wound with distribution cable.In this method, need cost a lot of money and make great efforts cable hank to be risen in the boiler room with a lot of times.In addition, owing to there is not the place to place this cable hank in the boiler room, therefore being difficult to cable hank provides the place.
In said method, the end of distribution cable is drawn up, owing to be pulled through journey by dependent manual operation on being somebody's turn to do, therefore also worries about for the poor efficiency of hard work and work.
Draw in the method for distribution cable at the shuttling movement that adopts lead, lead and distribution cable respectively have by solid conductor forms by the structure of twisting, so that reception tension force, lead and distribution cable all rotate towards a direction of separating strand for every kind.Therefore, can expect that lead and distribution cable can (especially in vertical direction) twisted together mutually, so just need additionally to provide a partition member to be used for preventing that lead and distribution cable are twisted together mutually.
In addition, in said method, owing to this structural reason of dilatory distribution cable, distribution cable can not be forwarded and be crossed lead.For distribution cable being connected to certain device or the similar device that is placed on the lead front, distribution cable also must be drawn distribution cable from the terminal point of lead with manpower after dilatory by lead, need a lot of the effort and the time thus.
When on long distance, laying distribution cable, be connected to distribution cable on the lead continuously and many ground are placed on and lay on the route with manpower or alternate manner.At this moment, one first lead of pulling down from distribution cable does not help to transmit distribution cable forward, so the laid processes of distribution cable is only undertaken by next the root lead that is connected to distribution cable like this.Like this, when distribution cable is approaching more when laying route terminal point one side, the required power of dilatory distribution cable is just big more, can damage the end of distribution cable thus.When laying apparatu was assisted in configuration one between lead, the tension force on the distribution cable can be disengaged.Yet can produce in this such as other shortcoming such as device complexity and inconvenient operation.
On the basis of the shortcoming of considering above-mentioned conventional method, the construction method and a kind of cable-laying gear that the purpose of this invention is to provide a kind of cabling, can when transmitting distribution cable forward, avoid dragging in the distribution cable and produce twisting, even and lay in long distance and also can realize in the distribution cable reliably laying.
For achieving the above object, place a band shape belt with a guide wheel along a cable laying line in the present invention, and apply actuating force with this belt that circulates with the driving pinch wheels.A kind of cable connecting arrangement with simple structure as the face grab can be used to cable is connected with belt, wherein can adopt the simple mechanism that an end of cable is pressed or tipped in the belt surface that cable is connected on the belt.In other words, provide a kind of cable-laying gear in the present invention, wherein laying belt is by the tensioning of guide wheel institute, and cable connecting arrangement is provided on the laying belt surface, and thus the end of distribution cable is connected on the laying belt.In addition, laying belt is provided with a drive unit and a tensioning apparatus, and when laying belt was moved, the deflection of belt was absorbed thus.
When cable-laying gear was configured as described above, because the guiding face of laying belt contacts with guide wheel all the time, although be added on the laying belt from the tension force of distribution cable, the attitude of belt was not changed and laying belt is not rotated.So distribution cable is dragged and can not produced twisting between laying belt and distribution cable.
Make by such structure that laying belt and cable are clamped takes turns on some point that is clamped on the cable laying route, though when the end of cable by when laying belt is pulled down, cable still can be unceasingly be transmitted with the operation of laying belt.Therefore, after cable end arrives the terminal point side of a cable laying route of a laying belt, the end of cable is sent by the cable unit of pulling down from laying belt and cable is laid towards the next one with laying belt, and cable can be sent forward and cross whole laying belt thus.So,, so just be easy to cable is passed to next root laying belt from a laying belt continuously as laying belt being arranged to along form multistage on the cable laying route.Because cable is to be connected other laying belt under the top laying belt of cable end to catch and transmit, to the driving of laying belt and do not require big power, in addition, also avoided with loading section be applied on the cable.
When forming a curved zone in laying belt, if laying belt is configured to be grasped between guide wheel and the cable, then cable can not be grasped between guide wheel and the laying belt, so cable can successfully be removed from laying belt.Laying belt can be reversed the laying belt that is used for disposing above-mentioned situation.At this moment, if provide an opening that is used to tear open cable in guide wheel one side, that is one the opening that cable is removed be provided at laying belt around the cable reverse on the path time, then cable has been laid fully after only need just can like a cork it be unloaded from laying belt mobile on the Width of cable in laying belt.

The distribution cable 16 that is laid by the cable-laying gear 10 of structure as previously mentioned is wrapped on a slice cable dish 44 usually.When laying distribution cable 16, cable hank 44 is placed in outside cable-laying gear 10 ends, and the end of distribution cable 16 is then spurred towards cable-laying gear 10.Face grab (cable one side) 32 is configured in the end of distribution cable 16 as described above.The end of distribution cable 16 is connected on the face grab (cable one side) 32 carries out with a net type clamping net 48 and a reversing device 46; this reversing device 46 is provided between distribution cable 16 and the face grab 32; even like this when distribution cable 16 rotations; this rotation is absorbed and can avoids being delivered to laying belt 18; in addition, the end of distribution cable 16 also can protectedly exempt from the damage that causes because of dilatory load.
Below illustrate and use the sequential steps that the cable-laying gear 10 of stating structure lays distribution cable 16.
Cable hank 44 is placed in the outside of cable-laying gear 10 1 sides that are configured in the pipeline 14, and this cable-laying gear 10 will be laid in together with the distribution cable 16 of (thing is laid in conduct in pipeline 14) in the pipeline.Because face grab (cable one side) 32 is provided for the end of distribution cable 16 in advance through reversing device 46 and clamping net 48, face grab (cable one side) 32 is connected on the face grab (belt one side) 30 that is bonded on the laying belt 18.After distribution cable 16 ends were connected on the laying belt 18, drive unit 34 was brought into operation and moves laying belt 18.
During operation laying belt 18, distribution cable 16 is sent along the cable laying route with laying belt 18.In laying belt 18 operations, guiding face 12 contacts with guide wheel 20, can obtain the stability of attitude like this, and then rotatablely moving thus just can not occur on one's body the laying belt 18.So laying belt 18 and distribution cable 16 time just can not twine mutually in operation, to dragging of distribution cable 16 just can be correct enforcement.When the end of distribution cable 16 reached the change direction zone 42 of cable-laying gear 10, drive unit 34 was stopped.At this moment, the position of the end of distribution cable 16 that is face grab (cable one side) 32 is between drive unit 34 and change direction zone 42, and face grab (belt one side) 30 and face grab (cable one side) 32 are separated like this.Under this state, drive unit 34 is started once more moves laying belt 18.Because distribution cable 16 is grasped in the drive unit 34 with laying belt 18, even when the end of distribution cable 16 and the surface disengagement of laying belt 18, distribution cable 16 still is moved with laying belt 18.Like this, the end of distribution cable 16 is forwarded to cross changes direction zone 42, and consequently: distribution cable 16 can be connected to a control board or electricapparatus and the device (not shown) that is configured in cable-laying gear 10 fronts.
In this embodiment, a cable connecting arrangement is designed to the face grab, but this cable connecting arrangement is not limited to present embodiment and can takes various forms.Fig. 6 illustrates an application examples of this cable connecting arrangement, and this moment, one adhesive was installed on the whole surface of laying belt 18.If this adhesive 50 is provided on the whole surface of laying belt 18 as shown in the figure, distribution cable 16 can be transmitted and need not to provide binding site in laying belt 18 and 16 of distribution cables.Please note: a contact roller 52 is used to increase the cohesive force of 50 of distribution cable 16 and adhesive, and one separates wheel 54 separating properties that then are used to increase between distribution cable 16 and the adhesive 50.Consequently: a plurality of distribution cables 16 can be transmitted with respect to laying belt 18, have then improved operating efficiency thus.
Fig. 7 is a side elevation view of this boiler room when cable-laying gear 10 is used to the boiler room of a cogeneration power plant.As shown in the figure, in the boiler room 56 of this cogeneration power plant, one be used for distribution cable 16 pass wherein distribution pipeline 58 constructed in the boiler room 56 within the walls outer.Cable-laying gear 10 is placed the route of following distribution pipeline 58.When and distribution cable very long such as the cable laying route in the thermal power plant boiler room 16 laid when becoming to be divided in distribution pipeline 58 branch form, provide 10 of individual cable laying apparatus to reduce operating efficiency.So just, designed a kind of method, this method is arranged on the distribution pipeline 58 a plurality of cable-laying gears 10 continuously.Fig. 8 illustrates one first application examples of the construction method of this cabling.
As shown in the figure like that in the continuous process that a plurality of cable-laying gears 10 is arranged in the distribution pipeline 58, when the end of distribution cable 16 arrives the change direction zone 42 that is arranged in the first cable-laying gear 10A, face grab (cable one side) 32 and face grab (belt one side) 30 are separated, and the end of distribution cable 16 is sent forward to cross and changed direction zone 42.The end of the distribution cable 16 that is sent is connected to next laying belt 18B, and distribution cable 16 is then forwarded with next laying belt 18B.At this moment, distribution cable 16 still contacts with the first laying belt 18A, and like this by operating the first laying belt 18A simultaneously, distribution cable 16 can be transmitted a quite long distance and not need to increase the power of each independent drive unit 34 of cable-laying gear 10.Because unique end of distribution cable 16 is not stowed, the load on this end of distribution cable 16 reduces, the damage of having avoided the cable rete to cause because of reasons such as overloads thus.Cable-laying gear 10 not only is configured on the main road line of distribution pipeline 58, and is configured on other route, and distribution cable 16 can easily be laid with branch's form.
As shown in Figure 7, the laying belt 18 of cable-laying gear 10 is not always put very directly, often may be placed by the turn of bilge along distribution pipeline 56.For form a turn of bilge on laying belt 18, guide wheel 20 must be placed in the curved zone.Yet when distribution cable 16 was sandwiched between guide wheel 20 and the laying belt 18, a concentrated stress was added to distribution cable 16, after cable laying is finished, just was difficult to distribution cable 16 is pulled down from cable-laying gear 10 like this.Like this, in the curved zone of laying belt 18, distribution cable 16 requires to be positioned at outside the curved point of laying belt 18.Fig. 9 is an explanatory diagram, and the laying belt 18 by a curved point is shown.Wherein have 2 curved points 60 and laying belt 18 to be configured to a stepped form as shown in the figure, laying belt 18 need be reversed in its certain midpoint, so that make distribution cable 16 be positioned at outermost.If laying belt 18 is reversed (for example: be twisted into a spirality), when distribution cable 16 is unloaded by the opposite side of slave plate shape support 24 (see figure 3)s, 16 of distribution cables are dispersed on the whole dismounting opening, laying belt 18 becomes a barrier like this, cause inconvenience thus to dismounting distribution cable 16, so, when reversing laying belt 18, should note the direction reversed, make laying belt 18 be twisted into opening on the direction of sealing disassembly distribution cable 16 not.
Respectively the do for oneself top view and the front view of an application examples of cable-laying gear 10 of Figure 10 and Figure 11.From figure, know and see, dispose the pipeline 14 of higher level and subordinate.In the laid processes of the distribution cable 16 in each pipeline 14, laying belt 18 is reversed in change direction zone 42, and goes out towards pipeline 14 1 laybacks.When the both ends of laying belt 18 are all gone out towards pipeline 14 1 laybacks and the middle body of laying belt 18 when being extended on the pipeline 14, the process of laying distribution cable 16 in upper and lower pipeline 14 can be carried out simultaneously, thereby can improve the efficient of the work of laying.As shown in the figure, in subordinate's pipeline 14, provide a cable-laying gear, itself does not have drive source but obtain rotary speed from the operation power that is clipped in the belt between roller, and can transmit before tomorrow with laying belt 18 nipped distribution cables 16 with this rotating speed that obtains.Thus, need not to change the place that is used for being provided with the drive unit 34 that is provided at higher level's pipeline 14, just can in upper and lower two-stage, carry out the cable laying process.
In this embodiment, guide wheel 20 is used to guide laying belt 18, as long as but can contact laying belt 18 guiding faces 12 and energy stable operation laying belt 18, just guide wheel 20 need not to be limited.For example, substitute guide wheel 20, can use one with ribbing slide plate, be used to prevent belt dropping in its both sides.In an embodiment, laying belt 18 is interpreted into tape loop, but also is not limited thereto.For example, laying belt 18 can resemble the goods of goods yard by on the guide wheel 20 that is provided at cable-laying gear 10 two ends, and laying belt 18 can be moved by rotating guide wheel 20.
In addition, in this embodiment, drive unit 34 and contact roller have been adopted as conveyer; But also be not limited thereto.Conveyer and pinch wheels can separately be provided in the cable-laying gear 10.
