[0002] In the construction of electromechanical facilities in super high-rise buildings, cable laying is one of the important construction projects. At present, the main method used for super high-rise cable construction is the suspended cable construction method. After the main body of the cable bracket is fixed on the cable shaft, the cable head is lifted by a winch, and then the cable is passed through each floor from bottom to top and installed and routed accordingly. In order to protect the cable, it is necessary to set a guide wheel at the upper limit of the shaft, and after the cable is lifted, the cable is fixed to the cable bracket with a cable fixing clamp. After the cable is installed, the guide wheel is removed. Since the construction and operation of the cable are all in the shaft, the installation of the guide wheel and the fixing clamp is also carried out in the shaft. Therefore, how to improve the efficiency of cable fixing operations installed at super high-rise buildings is of great significance. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a cable fixing structure for super high-rise electromechanical installation, including a frame, a ring body 1, a guide wheel 2 and an arc-shaped clamping plate 3, the frame is used to be fixed on the shaft wall, the ring body 1 is detachably installed on the frame, the guide wheel 2 and the arc-shaped clamping plate 3 are centrally symmetrically installed on the ring body 1, and the guide wheel 2 and the arc-shaped clamping plate 3 are staggered in the circumferential direction of the ring body 1, the radial positions of the guide wheel 2 and the arc-shaped clamping plate 3 on the ring body 1 are adjustable, and the guide wheel 2 is axially arranged perpendicular to the cable hanging direction.

[0022] When installing cables in a suspended manner, the cable fixing structure of the super high-rise electromechanical installation can be installed in the shaft at one time according to the requirements of the cable routing. Then, adjust the position of the guide wheel 2 and the arc-shaped clamp plate 3 on the ring body 1 so that the guide wheel 2 is located on the inner side of the arc-shaped clamp plate 3. After that, pass the rope head of the winch through the center of the ring body 1 from top to bottom, and then fix it to the cable head. During the cable lifting process, the cable passes through the center of each ring body 1 from bottom to top. At the same time, the cable is limited and guided by the guide wheel 2. When the cable needs to be fixed after it is lifted over the ring body 1, directly operate the guide wheel 2 and the arc-shaped clamp plate 3 so that the arc-shaped clamp plate 3 moves inward on the ring body 1 and clamps the fixed cable. In this way, the construction work of laying cables in super high-rise electromechanical installation can be completed more quickly and conveniently.

[0023] Furthermore, in the above embodiment, a support block 4 is fixedly installed on the inner surface of the ring body 1, and a slide groove 5 is provided on both sides of the support block 4. Slide blocks 6 that slide in the slide groove 5 are fixedly provided on both sides of the wheel frame of the guide wheel 2 and both sides of the arc plate, and adjusting bolts 7 are installed on the outer side of the wheel frame of the guide wheel 2 and the outer side of the arc plate. The ring body 1 is provided with a threaded hole 8 that is threadedly matched with the adjusting bolt 7. By rotating the adjusting bolts 7 corresponding to the guide wheel 2 and the arc clamping plate 3 respectively, the adjusting bolts 7 can control the guide wheel 2 and the arc clamping plate 3 to move radially inward and outward on the ring body 1, respectively, so that when lifting the cable, it is mainly the guide wheel 2 that guides and stabilizes the cable radially. When fixing the cable, it is mainly the arc clamping plate 3 that clamps on the surface of the cable to achieve the fixing of the cable.

[0024] A groove 9 is formed between two adjacent support blocks 4, and the guide wheel 2 and the arc-shaped clamping plate 3 can be received in the groove 9. When lifting the cable, the arc-shaped clamping plate 3 is received in the corresponding groove 9, and the inner side of the wheel surface of the guide wheel 2 is extended from the inner notch of the groove 9, so that the guide wheel 2 contacts the cable surface. When fixing the cable, the arc-shaped clamping plate 3 is removed from the groove 9 and directly clamped to the cable surface.

[0025] The upper and lower sides of the support block 4 are both provided with arc-shaped auxiliary clamping plates 10, and the upper and lower ends of the arc-shaped clamping plates 3 are axially extended outward relative to the upper and lower side surfaces of the ring body 1, and one side of the auxiliary clamping plate 10 is fixedly mounted on the arc-shaped clamping plate 3 on one side of the support block 4. In the process of the arc-shaped clamping plates 3 clamping the cable, the auxiliary clamping plates 10 fill the gap between two adjacent arc-shaped clamping plates 3, so that the arc-shaped clamping plates 3 have more contact surfaces with the cable surface, thereby improving the clamping effect of the arc-shaped clamping plates 3 on the cable.

[0026] The ends of the arc-shaped clamping plate 3 and the auxiliary clamping plate 10 away from the ring body 1 are bent outward to form a guide portion 11. During the cable lifting process, the guide portion 11 has a better guiding effect on the rope of the lifting cable, so that the cable head can pass through each ring body 1 more smoothly from bottom to top.

[0027] The two sides of the ring body 1 are fixedly sleeved with sleeve blocks 12, and the sleeve blocks 12 are fixedly connected with a support plate 13 on one side of the axial direction of the ring body 1, and the end of the support plate 13 away from the ring body 1 is fixedly connected with a mounting plate 14. The mounting plate 14 and the support plate 13 are staggered with the ring body 1 in the axial direction to provide sufficient space for operating the adjustment bolt 7. The frame includes two parallel longitudinal beams 15 and a cross beam 16 arranged between the two longitudinal beams 15, and the mounting plate 14 is detachably mounted on the cross beam 16. The cross beam 16 is a square tube, and the mounting plate 14 includes two channel steel-like plates that can be respectively sleeved on the cross beam 16, and the two channel steel-like plates are fixed by fastening bolts 17 passing through the cross beam 16. The cross beam 16 and the two plates are both provided with mounting holes for the fastening bolts 17 to pass through, and the fastening nuts are installed after the fastening bolts 17 pass through the mounting holes.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
