Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
The utility model provides a cable laying device convenient to blowing, as shown in figure 1, including the tractor 7 that is used for pulling 8 heads of cable, holds in the palm chain 3, fixed bolster 2 and cable drum mount 1, cable drum mount 1 is fixed subaerial, is equipped with the ascending semicircular groove of opening on cable drum mount 1, and the semicircular groove is used for installing the spool of cable drum 11, and the hoist and mount of cable drum 11 is convenient for to such design.
As shown in fig. 2, the chain support 3 includes two chains 31 and a plurality of cross braces disposed between the two chains 31, specifically, the cross braces are V-shaped cross braces 32, two ends of the V-shaped cross braces 32 are connected to the axes of the two chains 31, and the V-shaped cross braces 32 do not interfere with the transmission function of the chains 31. At the bottom of the V-shaped cross-brace 32 is provided an arc-shaped portion for carrying the cable 8. Such a design can increase the rigidity of the carrier chain 3, thereby protecting the cable 8 and preventing the cable 8 from falling out of the carrier chain 3.
As shown in fig. 3, the fixing bracket 2 is fixed on the ground and is used for fixing one end of the supporting chain 3. The fixed support 2 is provided with a notch, a pressing wheel 21 is arranged in the notch, and the pressing wheel 21 is used for abutting against the cable 8. Because the cable drum 11 is very wide, the cable 8 can swing when being discharged, and the notches, the V-shaped cross braces 32 and the pressing wheels 21 can eliminate the influence of the swing of the cable 8 on the laying, so that the cable 8 is always positioned in the supporting chain 3.
The tractor 7 is provided with a clamping structure 72, and the clamping structure 72 is used for opening and closing the head of the connecting cable 8. As shown in fig. 1 and 3, the tractor 7 is provided with a duplex sprocket 4 connected with the supporting chain 3, and the duplex sprocket 4 is connected with a wheel 71 of the tractor 7 through a reversing transmission mechanism, so that the linear velocity of the duplex sprocket 4 is the same as the linear velocity of the traveling of the wheel 71. Specifically, the reversing transmission mechanism comprises a gear transmission pair 5 and a belt transmission pair 6. Wherein, the driven gear in the gear transmission pair 5 is coaxially connected with the duplex chain wheel 4, the driving gear in the gear transmission pair 5 is coaxially connected with the driven pulley in the belt transmission pair 6, and the driving pulley in the belt transmission pair 6 is coaxially connected with the wheel 71. The gear transmission pair 5 can change the rotation direction of the driven pulley, so that the rotation direction of the duplex sprocket 4 is the same as the rotation direction of the wheels 71.
In order to realize the same linear speed of the duplex sprocket 4 and the wheel 71, in the embodiment, for the sake of simplifying the design, the pitch circle diameter of the duplex sprocket 4 is the same as the diameter of the wheel 71, and the transmission ratio of the gear transmission pair 5 and the belt transmission pair 6 is 1: 1. It should be noted that when the gear ratio of the gear pair 5 is N:1, the gear ratio of the belt gear pair 6 is 1: N, so that the same linear speed of the duplex sprocket 4 and the wheel 71 can be achieved.
Since the linear velocity of the duplex sprocket 4 is the same as the linear velocity of the traveling wheel 71 and the rotation direction is the same, and the head of the cable 8 is fixed to the tractor 7, the cable 8, the carrier chain 3 and the wheel 71 have linear velocities in the same direction. Further, it is understood that, in theory, there is no relative movement between the cable 8 and the carrier chain 3, no friction occurs, and the carrier chain 3 is unlikely to cause frictional damage to the insulation layer of the cable 8. It can also be seen that, in theory, the travel distance of the tractor 7 is the same as the pull-out length of the carrier chain 3, which enables the carrier chain 3 to be kept in a taut state at all times, preventing the cable 8 from hanging. In actual use, however, there is actually a small difference in linear velocity between the cable 8, the tow chain 3 and the wheel 71. For example, the influence of the uneven road surface on the driving distance of the tractor 7 can cause that the pull-out length of the supporting chain 3 in a certain period of time is greater than the driving distance of the tractor 7, and at the moment, the supporting chain 3 is in a loose state and cannot be tightened; it also causes the pull-out length of the carrier chain 3 in a certain period of time to be less than the travel distance of the tractor 7, at which time the carrier chain 3 is excessively tight and is liable to break.
It is known that, unlike gear drives and chain drives, belt drives slip, which is just to solve the above mentioned problems. In practical use of the present invention, the pitch circle diameter of the duplex sprocket 4 is slightly larger than the diameter of the wheel 71. Thus, when the pull-out length of the supporting chain 3 is greater than the running distance of the tractor 7, the linear speed of the duplex chain wheel 4 is slightly greater than the linear speed of the running of the wheel 71, so that the chain is restored to a tight state; when the pull-out length of the support chain 3 is less than the running distance of the tractor 7, the belt starts to slip, the tightening degree of the support chain 3 is reduced, and the support chain 3 is prevented from being broken.
In order to achieve an adjustable laying height, the legs of the fixing support 2 are height-adjustable. For the duplex chain wheel 4, on the premise that the axis of the driving gear is fixed, the driven gear coaxial with the duplex chain wheel 4 can rotate around the axis of the driving gear, so that the height of the duplex chain wheel 4 can be adjusted. Since the cable 8 is laid over a long distance, the carrier chain 3 is also long, and a storage box 73 for storing the carrier chain 3 is provided in the tractor 7 to prevent entanglement.
When the invention lays a cable on the road surface or in a tunnel, as shown in fig. 4, firstly, the height of the fixed bracket 2 and the duplex sprocket 4 is adjusted to make the laying height suitable for the connection height of the telegraph pole 9; then the head of the cable 8 is inserted into the notch of the fixed bracket 2 and then is connected with the clamping structure 72; and finally, starting the tractor 7 to pull the cable 8, so that the cable 8 and the supporting chain 3 synchronously move along with the tractor 7, and at the moment, hanging a connecting hardware fitting 91 on each telegraph pole 9 by constructors to fix the cable 8 on the telegraph pole 9. After the cable drum 11 is discharged, the cable drum fixing frame 1 and the fixing support 2 are lifted to the next laying point, a new cable drum 11 is lifted, and the discharging and laying operation is repeated.
Therefore, the construction personnel is not required to pull the cable 8 in the whole process, and the cable 8 is always in a tightened state in the laying process, so that the construction personnel can greatly reduce the physical consumption of the construction personnel, and the suspension problem and the floor mopping friction problem of the cable 8 in the laying process are skillfully solved.
The present invention is not described in detail in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
