Description

Technical Field

[0001] The utility model relates to the field of rail transit cable construction, in particular to an anti-seismic support and hanger for rail transit cables. Background Art

[0002] As one of the symbols of modern cities, rail transit has the characteristics of large capacity, high speed and frequent service, which can effectively alleviate the problem of urban traffic congestion. During the construction of rail transit, a large number of cables need to be laid in the tunnel to serve as conductive media such as power supply and communication. While laying the cables, supports and hangers are usually used as cable laying brackets. For example, a new type of cable hanger disclosed on the China Patent Network (public announcement number CN218005733U) shows that when this type of hanger is in use, the hanger body can facilitate the fixing and installation of cables. Moreover, since the upper end of the hanger body and the fixing seat are movable structures, they can adapt to the installation requirements of different curvature sections and ensure that the fixing groove and cables are in a horizontal state. According to on-site requirements, multiple layers can be set to meet the laying of multi-circuit cables, and they can also adapt well to the fixation of multi-circuit cables with different sections.

[0003] However, the cable hangers used in the aforementioned patents and the existing market still have some shortcomings: the existing method uses a movable structure to drive the support plate to swing up and down, and swing-adjusts the position of the cable fixing groove to adapt to the installation position of cables at different heights. The movable adjustment method has limited bearing capacity. When the cable is heavy, it is very easy to exceed the self-locking force of the movable structure, resulting in unstable cable installation. The swing adjustment position is limited, and the flexible adaptability of the cable is relatively low. To this end, those skilled in the art provide a seismic support and hanger for rail transit cables to solve the problems raised in the above background technology. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a seismic support and hanger for rail transit cables, which solves the problems of the prior art in that the existing cable support and hanger has relatively simple flexibility and poor support stability.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-seismic support and hanger for rail transit cables, comprising a side mounting frame and a guide screw rod installed inside the side mounting frame bracket;

[0006] The bracket of the side mounting frame is provided with multiple sets of lifting brake mechanisms arranged along the axis direction of the guide screw, and a support truss is installed on one side of the lifting seat of each set of lifting brake mechanisms, and the support truss is provided with multiple sets of cable grooves arranged along the direction of its plate frame;

[0007] The lifting brake mechanism includes a brake seat installed inside the side mounting bracket along the direction of the guide screw shaft, a rotating seat is provided at the bottom of the support of the brake seat, and a transmission wire sleeve is provided in the middle of the support of the rotating seat and is ringed on the guide screw, and a brake knob opposite to the transmission wire sleeve is provided on one side of the support of the brake seat.

[0008] As a further technical solution of the present invention: the output shaft of the brake knob is installed with a bevel gear B, and the outer side of the shaft sleeve of the transmission sleeve is provided with a bevel gear A meshing with the bevel gear B.

[0009] As a further technical solution of the present invention: the brake seat is a square seat structure, and the brake seat and the side mounting frame are slidably connected to each other.

[0010] As a further technical solution of the present invention: lifting slides are provided on both sides of the bracket of the side mounting frame, and lifting slides guided by the lifting slides are provided on both sides of the support of the brake seat.

[0011] As a further technical solution of the present invention: the support truss is a trapezoidal structure along the slotting direction of the cable trough.

[0012] As a further technical solution of the present invention: multiple groups of cable troughs are all semicircular structures, and the aperture size of each group of cable troughs increases from bottom to top along the ladder surface of its supporting truss, and the inner groove of the cable trough is padded with a rubber gasket.

[0013] The utility model provides a seismic support and hanger for rail transit cables, which has the following advantages compared with the prior art:

[0014] When installing and using the rail transit cable support and hanger designed in this paper, the side mounting frame is used as the mounting platform to install the support and hanger on the inner wall of the tunnel. Then, based on the combination of the lifting brake mechanism and the guide screw as the braking source, the support truss is pushed to lift and brake, and the height and position of its cable trough are flexibly adjusted to adapt to the laying and installation of cables of different heights. While its flexible adjustability is better, the adjustment and braking stability is better, and it can stably bear the laying and supporting work of cables of different weights. After the cables are laid, its height and position can also be continuously adjusted to flexibly adapt to the on-site installation environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-3 The utility model provides a technical solution for an anti-seismic support and hanger for rail transit cables: an anti-seismic support and hanger for rail transit cables, comprising a side mounting frame 1 and a guide screw 2 installed inside the bracket of the side mounting frame 1, a plurality of lifting brake mechanisms are arranged inside the bracket of the side mounting frame 1 along the axis direction of the guide screw 2, the lifting brake mechanism comprises a brake seat 3 installed inside the bracket of the side mounting frame 1 along the axis direction of the guide screw 2, a rotating seat 9 is provided at the bottom of the support of the brake seat 3, and a transmission wire sleeve 10 which is ringed on the guide screw 2 is provided in the middle of the support of the rotating seat 9, and a transmission wire sleeve 10 which is ringed on the guide screw 2 is provided on one side of the support of the brake seat 3 0 relative to the brake knob 5, the output shaft of the brake knob 5 is installed with a bevel gear B12, and the outer side of the shaft sleeve of the transmission wire sleeve 10 is provided with a bevel gear A11 meshing with the bevel gear B12. By rotating the brake knob 5, the bevel gear B12 is driven to rotate, and the meshing transmission of the bevel gear B12 and the bevel gear A11 is utilized to push the transmission wire sleeve 10 to rotate along the rotating seat 9. While the transmission wire sleeve 10 rotates, the meshing transmission with the guide screw rod 2 is utilized to convert the rotational force into a lifting thrust, pushing the brake seat 3 to lift and slide along the side mounting frame 1, and adjusting the height and azimuth of the support truss 7 to adapt to the flexible and changeable installation environment on site.

[0021] The brake seat 3 is a square seat structure, and the brake seat 3 and the side mounting frame 1 are slidably connected to each other. Lifting slides 6 are provided on both sides of the bracket of the side mounting frame 1, and lifting slides 4 guided by the lifting slides 6 are provided on both sides of the support of the brake seat 3. When the brake seat 3 is lifted and braked along the side mounting frame 1, it uses the guiding sliding of the lifting slide 4 and the lifting slide 6 to play a lifting and guiding role on the one hand, and a side support role of the arm force on the other hand to disperse the forward tilting gravity of the brake seat 3.

[0022] A supporting truss 7 is installed on one side of the lifting seat of each lifting brake mechanism. The supporting truss 7 has multiple groups of cable grooves 8 arranged along the direction of its plate frame. The supporting truss 7 has a trapezoidal structure along the slotting direction of the cable grooves 8. The multiple groups of cable grooves 8 are all semicircular structures, and the aperture size of each group of cable grooves 8 increases from bottom to top along the ladder surface of the supporting truss 7. The inner groove of the cable groove 8 is padded with a rubber gasket. By arranging cable grooves 8 of different aperture sizes on the supporting truss 7, it can adapt to the support work of cables of different thicknesses. By adding rubber washers in the cable grooves 8, on the one hand, it can play a sheathing role to improve the stability of cable laying, and on the other hand, it can play an elastic shock-absorbing role and have a seismic buffering effect.

[0023] The working principle of the present invention is as follows: when the support bracket is used as the installation bracket of the rail transit cable, the side mounting frame 1 is installed on the inner wall of the tunnel along the cable laying direction, and then the support height is adjusted and calibrated based on the laying height of the cable on site. During the adjustment process, the brake knob 5 is rotated to drive the bevel gear B12 to rotate, and the meshing transmission of the bevel gear B12 and the bevel gear A11 is used to push the transmission wire sleeve 10 to rotate along the rotating seat 9. While the transmission wire sleeve 10 rotates, the meshing transmission with the guide screw rod 2 is used to convert the rotational force into a lifting thrust, pushing the brake seat 3 to lift and slide along the side mounting frame 1, and adjusting the height and orientation of the support truss 7. Then, according to this method, the height and orientation of the support truss 7 are adjusted and calibrated in turn. After the calibration is completed, the cables are laid one by one in the cable groove 8. After the laying is completed, the support height can also be adjusted in real time according to the on-site installation environment to flexibly adapt to the on-site installation environment. Its adjustment adaptability is better and the support is more stable.
