DETAILED DESCRIPTION

[0026] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0027] See also Figure 1 The cable auxiliary installation device of the present invention comprises a stable support base frame and a cable release device and a cable conveying guide device installed on the stable support base frame. The stable support base frame is used to support the cable release device and the cable conveying guide device, the cable release device is used to actively unwind the cable, and the cable conveying guide device is used to convey, guide and laterally shift the cable, and gradually release the stress of the cable.

[0028] The cable auxiliary installation equipment can be applied in two ways: one way is vehicle-mounted, in which case the entire equipment is installed on the platform of an engineering vehicle, and the engineering vehicle moves along the construction path, such as in the construction scenario of installing cables under a bridge, in which case the stable support frame is directly installed and fixed to the engineering vehicle; the other way is floor-standing, in which case the entire equipment moves along a temporary ground track on the ground, such as in the construction scenario of installing cables in corridors and underground tunnels.

[0029] In this embodiment, the stable support frame includes two opposite side beams 2, and a connecting crossbeam 15 is installed between the two side beams 2; track wheels 3 are installed at the bottom of the front end and the bottom of the rear end of the side beam 2, and also includes a ground track 1 and the track wheels 3 fall on the ground track 1. At least one of the track wheels 3 has a travel drive device, and the travel drive device is a travel reducer. The ground track 1 is laid section by section on the ground of the construction scene, that is, the ground track 1 behind the equipment is disassembled and laid and installed on the ground in front of the equipment, so that the cable auxiliary installation device is shifted along the set installation path.

[0030] See also Figure 2 , Figure 3 and Figure 4 , we can see that:

[0031] The cable release device includes a support frame 5 installed in the middle of the stable support chassis. In this embodiment, the support frame 5 includes two left and right door-type frames. The bottoms of the two door-type frames are fixedly connected to the stable support chassis by using an adapter 4. Specifically, the bottoms of the two door-type frames are fixedly connected to the two side beams 2 by using an adapter 4. A bottom crossbeam 18 is installed between the bottoms of the two door-type frames, and a reinforcing connecting plate 17 is installed between the bottom crossbeam 18 and the door-type frames. The bottom crossbeam 18 and the reinforcing connecting plate 17 fixedly connect the left and right door-type frames as a whole.

[0032] A mounting and unwinding device 7 with adjustable height for mounting and actively unwinding the cable reel 6 is installed in the front middle of the support frame 5, two opposite friction assisting devices 8 for assisting the unwinding of the cable reel 6 are installed on the front top of the support frame 5, a controllable lifting limit device 9 is installed at the rear of the support frame 5, and a controllable opening and closing cable limit assembly is provided on the top of the limit device 9.

[0033] The cable reel 6 is installed on the mounting and unwinding device 7, which can be raised or lowered according to the size of the cable reel 6. The friction assist device 8 is used to provide auxiliary unwinding power to the cable reel 6 to reduce the burden of the mounting and unwinding device 7. The limiting device 9 with a cable limiting assembly is used to limit the upper cable 10 to prevent the cable 10 that has just been unwound from being separated from the auxiliary installation equipment due to its own stress.

[0034] In this embodiment, two relatively detachable supporting beams 16 are installed in the middle of the supporting frame 5, and the mounting and unwinding device 7 is installed and fixed between the front ends of the two supporting beams 16. Specifically, the root and the front of the supporting beam 16 are fixedly connected to the door-type frame of the supporting frame 5 with high-strength bolts. When the height position of the mounting and unwinding device 7 needs to be adjusted, the connection between the supporting beam 16 and the supporting frame 5 is first released, and then the height is raised or lowered and fixed again with high-strength bolts.

[0035] The mounting and unwinding device 7 includes two base plates 7-1 that are detachably connected to the ends of the supporting crossbeam 16, and the base plates 7-1 and the supporting crossbeam 16 can also be disassembled and assembled. An axle seat and a mounting shaft 7-5 are installed in the middle of the two base plates 7-1. An unwinding motor 7-3 and an unwinding reducer 7-2 for driving the mounting shaft 7-5 are also installed on one of the base plates 7-1. A mounting roller 7-4 is also provided in the middle of the mounting shaft 7-5. As shown in the figure, the mounting shaft 7-5 is a polygonal shaft, and a polygonal shaft hole is correspondingly provided in the middle of the mounting roller 7-4. The mounting shaft 7-5 is inserted into the shaft hole of the mounting roller 7-4 and retaining springs are provided on the outer sides of both ends to limit the position of the mounting roller 7-4.

[0036] Therefore, the mounting roller 7-4 can move on the mounting shaft 7-5, and the mounting roller 7-4 can also be removed from the mounting shaft 7-5. Generally, the outer diameter of the mounting roller 7-4 should be slightly smaller than the size of the center hole of the cable reel 6, so that when the cable reel 6 is loaded on the mounting and unwinding device 7, the mounting roller 7-4 is located in the center hole of the cable reel 6.

[0037] In this embodiment, the friction booster device 8 includes a base plate 8-2 detachably connected to the support frame 5, an axle seat and a booster shaft 8-5 are installed in the middle of the two base plates 8-2, a booster motor 8-1 and a gear set 8-3 for driving the booster shaft 8-5 are also installed on one of the base plates 8-2, and a booster friction wheel 8-4 is provided on the booster shaft 8-5. As shown in the figure, the booster shaft 8-5 is a polygonal shaft, and a polygonal shaft hole is correspondingly provided in the middle of the booster friction wheel 8-4. The booster shaft 8-5 is inserted into the shaft hole of the booster friction wheel 8-4 and a retaining spring is provided on the outer sides of both ends to limit the position of the booster friction wheel 8-4.

[0038] Therefore, the height of the friction assisting device 8 can be adjusted up or down as needed. Specifically, the connection between the base plate 8-2 and the support frame 5 is first released, and then the base plate 8-2 and the support frame 5 are fixedly connected with high-strength bolts after the height is adjusted. The position of the assisting friction wheel 8-4 on the assisting shaft 8-5 can be adjusted and the assisting friction wheels 8-4 of different sizes can be replaced as needed. In this way, the assisting friction wheel 8-4 of the friction assisting device 8 and the cable reel 6 can have a more suitable relative position relationship, thereby producing a more suitable friction assisting effect.

[0039] In this embodiment, the limiting device 9 includes a lifting base plate 9-4 and a longitudinal hydraulic cylinder 9-8 driving the lifting base plate 9-4 to move up and down. A guide wheel 9-5 is installed on the support frame 5 to provide a guide for the edge of the lifting base plate 9-4. Two left and right notches 9-6 are provided on the top of the lifting base plate 9-4 and the cable 10 passes through the notches 9-6. The cable limiting assembly is located on the top side of the lifting base plate 9-4. The longitudinal hydraulic cylinder 9-8 drives the lifting base plate 9-4 and its accessories to gradually descend from a high position, so that the notch 9-6 and the cable limiting assembly gradually decrease in height as the cable 10 on the cable reel 6 gradually decreases.

[0040] like Figure 3 As shown in , the cable limiting assembly includes a reinforcing longitudinal beam 9-7 fixedly mounted on a lifting base plate 9-4, a top cross beam 9-3 is mounted on the top of the reinforcing longitudinal beam 9-7, and the top cross beam 9-3 is fixedly connected to the top of the lifting base plate 9-4 to improve the overall structural strength, and two limiting pressure strips 9-2 and a horizontal hydraulic cylinder 9-1 driving the limiting pressure strips 9-2 to tilt are hingedly mounted on the top of the lifting base plate 9-4. The horizontal hydraulic cylinder 9-1 switches the limiting pressure strip 9-2 between a vertical posture and a horizontal posture. When the limiting pressure strip 9-2 is tilted (that is, in a horizontal posture), the cable 10 is limited in the gap 9-6 and will not fall out.

[0041] See also Figure 5 and Figure 6 , we can see that:

[0042] The cable conveying and guiding device includes a transverse track 14 installed on a stable supporting base frame and behind a supporting frame 5, a mobile chassis 13 with controllable transverse movement is provided on the transverse track 14, a bracket 12 is installed on the mobile chassis 13, and a plurality of conveying and guiding components 11 providing conveying and guiding functions for the cable 10 are installed on the top of the bracket 12.

[0043] like Figure 2 and Figure 5As shown in the figure, the transverse track 14 includes two channel steels arranged at the front and rear, and the two ends of the channel steels are respectively fixedly connected to the left and right side beams 2. The mobile chassis 13 includes a chassis and a travel assembly installed on the chassis, and the travel assembly includes two rows of front and rear travel wheels, which are respectively located in the channel steels of the two transverse tracks 14. Under the driving action of the travel assembly, the mobile chassis 13, the bracket 12 and the conveying guide assembly 11 can be translated and shifted left and right, and the upper cable 10 can be moved left and right accordingly.

[0044] The conveying guide assembly 11 comprises a base cross beam 11 - 1 , on which three front, middle and rear V-shaped supports 11 - 2 are fixedly mounted, and a space is formed inside the V-shaped supports 11 - 2 for the cable 10 to pass through.

[0045] A first arm 11-8 and a second arm 11-9 are hingedly mounted in the middle of the base crossbeam 11-1, and a torsion spring is mounted on the hinge shaft at the root of the two arms. Two left and right first conveying wheels 11-6 are mounted on the top of the first arm 11-8, and two left and right second conveying wheels 11-7 are mounted on the top of the second arm 11-9. Figure 6 As shown in the figure, the first arm 11-8 and the second arm 11-9 are both V-shaped arms, with their tips facing forward and backward respectively. When the cable 10 above applies downward pressure to the first conveying wheel 11-6 and the second conveying wheel 11-7, the torsion springs at the roots of the first arm 11-8 and the second arm 11-9 further contract, and the two arms expand forward and backward respectively, and the height of the first conveying wheel 11-6 and the second conveying wheel 11-7 is reduced. Conversely, when the cable 10 is removed, the first arm 11-8 and the second arm 11-9 are restored under the elastic force of the torsion spring. Figure 5 and Figure 6 The initial position in .

[0046] It also includes a conveying drive assembly that drives the conveying wheels (the first conveying wheel 11-6 and the second conveying wheel 11-7) to actively rotate, and the conveying drive assembly includes a conveying motor 11-13 and a driving sprocket 11-12 installed on the base beam 11-1, and transmission sprockets are installed on the wheel axles of the conveying wheels (the first conveying wheel 11-6 and the second conveying wheel 11-7) and in the middle of the support arms (the first support arm 11-8 and the second support arm 11-9), and the driving sprocket 11-12 and the transmission sprocket are connected by a conveying chain 11-14.

[0047] Specifically, the conveying motor 11-13 drives the driving sprocket 11-12 to rotate, and the driving sprocket 11-12 is connected to the transmission sprocket in the middle of the support arm by a conveying chain 11-14. The transmission sprocket in the middle of the support arm is connected to the transmission sprocket on the conveying wheel axle by a conveying chain 11-14, so that the conveying motor 11-13 realizes the driving rotation effect of the conveying wheel.

[0048] In this embodiment, a shaft sleeve 11-3 is installed between the ends of adjacent V-shaped supports 11-2, and a side shaft 11-4 is installed in the shaft sleeve 11-3, and three side wheels 11-5, namely front, middle and rear, are installed on the side shaft 11-4. It also includes a side drive assembly that drives the two side shafts 11-4 to rotate synchronously in opposite directions; the side drive assembly includes a side drive motor 11-10 installed at the bottom of the V-shaped support 11-2, and the side drive motor 11-10 uses a side drive chain 11-11 and a transmission sprocket to drive the side shaft 11-4 to rotate. Specifically, Figure 6 As shown in the figure, drive sprockets are installed on the left and right parts of the V-shaped support 11-2, and drive sprockets are installed on the two side shafts 11-4. The sprocket driven by the side drive motor 11-10 uses the side drive chain 11-11 and the drive sprocket to drive the side shaft 11-4 to rotate. The rotation directions of the two side shafts 11-4 are opposite, and thus the rotation directions of the left and right sets of side wheels 11-5 are opposite. Figure 6 In the conveying guide assembly 11 shown in the figure, the three side wheels 11-5 on the left side rotate in a clockwise direction, and the three side wheels 11-5 on the right side rotate in a counterclockwise direction.

[0049] The function of the above structure is to provide the cable 10 with the function of shifting to the inner space of the V-shaped support 11-2. When the cable 10 moves to the side in the inner space, the cable 10 contacts the side wheel 11-5, and the side wheel 11-5 provides the cable 10 with an inward and downward friction force, which can prevent the cable 10 from slipping out of the conveying guide assembly 11 to a certain extent. It is worth noting that: Figure 5 and Figure 6 The figure shown in the figure is used to illustrate the basic structure and operating principle of the conveying guide assembly 11. In fact, more first conveying wheels 11-6 and second conveying wheels 11-7 can be provided, thereby providing an elastic supporting surface with a conveying function for the cable 10, and the size of the side wheel 11-5 can also be larger.

[0050] In this embodiment, the cable conveying guide device includes three conveying guide components 11 in the front, middle and rear. The base beam 11-1 of the middle conveying guide component 11 is fixedly connected to the top of the bracket 12, and the adjacent V-shaped supports 11-2 of adjacent conveying guide components 11 are fixedly connected by bolts to form a whole.

[0051] The cable auxiliary installation equipment should also include a hydraulic station and a control cabinet to provide hydraulic and electrical control. The hydraulic station and the control cabinet can be installed on a stable support frame and controlled on-site by on-site accompanying personnel.

[0052] How to run:

[0053] The mounting and unwinding device 7 is disassembled from the front end of the supporting crossbeam 16, and the cable reel 6 is mounted on the mounting and unwinding device 7, and then the mounting and unwinding device 7 is reinstalled on the supporting crossbeam 16. At this time, at least one friction wheel 8-4 of the friction assisting device 8 should be in friction contact with the end face of the cable reel 6; the end of the cable 10 is pulled to make the cable 10 pass through the gap 9-6 of the limiting device 9, and the horizontal hydraulic cylinder 9-1 is operated to make the limiting pressure strip 9-2 fall down to close the gap 9-6 and confine the cable 10 in the gap 9-6; the unwinding part of the cable 10 falls on the cable conveying guide device, specifically, falls on the elastic support surface provided by the conveying guide component 11. As the cable 10 is unwound, conveyed and guided, the stress on the cable 10 is gradually released and transformed into a straight state;

[0054] When installing the cable 10, according to the preset position of the upper cable tray, the cable conveying guide device is controlled to move left or right on the transverse track 14 until the position is appropriate, and then the cable 10 is lifted to the cable tray by a small crane and fixed with a fixing piece; then the auxiliary equipment moves forward while continuing to unwind the cable 10. Specifically, when the vehicle-mounted mode is adopted, the engineering vehicle drives forward a certain distance, and when the ground mode is adopted, the ground track 1 behind the equipment is transferred to the front of the equipment, and the walking mechanism is controlled to move forward a certain distance along the ground track 1.
