Description

Technical Field

[0001] This invention relates to the field of urban rail transit technology, and more specifically, to a quick-installation power supply rail insulation support device. Background Technology

[0002] The urban rail transit power supply system is a system that provides the electrical energy required for the operation of urban rail transit. It not only provides traction power for urban rail transit electric trains, but also provides power for other facilities that serve the operation of urban rail transit, such as lighting, ventilation, air conditioning, water supply and drainage, communication, signaling, disaster prevention alarms, and escalators. Among them, electric trains generally use two methods for power supply: overhead contact network power supply and third rail power supply. Simply put, third rail power supply means that the power source is taken from the ground. The power source is not the train track, but a power supply rail parallel to the train track. The vehicle takes power from the power supply rail through a current collector. The power supply rail is fixed by an insulating support device to ensure safety.

[0003] A search revealed a quick-installation and adjustment power supply rail insulation support device disclosed in application publication number CN107627905A. This device includes an insulation bracket, an upper fastener, and nylon fastener plates. The insulation bracket has a J-shaped front end, a skirt in the middle, and a mounting base at the rear. The bottom of the J-shaped structure has an inverted trapezoidal groove I, and the top has a through hole. The nylon fastener plate has a trapezoidal groove III, with flanges on both ends. The nylon fastener plate is fitted into the inverted trapezoidal groove I. The upper fastener has a downward-opening trapezoidal groove II, with a rectangular through hole on its inner top surface. Another nylon fastener plate is fitted into the trapezoidal groove II. The upper fastener is fitted onto the top of the J-shaped structure through the rectangular through hole and is limited by a cotter pin inserted through the through hole. This invention is mainly applicable to small clearance conditions on the side of power supply rails in urban rail transit, and is simple to install and easy to adjust.

[0004] However, the above design still has shortcomings. The design has a pre-embedded metal insert with internal threads in the mounting base, which means that screws and nuts are needed to fix the mounting base to the sleeper. Most existing technologies also use screws and nuts for installation. Although the screw and nut installation method is low-cost, it also has some disadvantages. First, the train will generate vibration when it runs on the track, and the vibration will be transmitted to the mounting base through the sleeper, causing the connection between the screw and nut to loosen. Therefore, the staff needs to check and reinforce the connection frequently. Second, urban rail is laid underground, and the underground environment is relatively humid, which can easily cause the screw and nut to rust, thereby reducing the tightness of the screw and nut, and making disassembly more difficult. Summary of the Invention

[0005] This invention provides a quick-installation power rail insulation support device, solving the problem of using screws and nuts in related technologies. While the screw and nut installation method is low-cost, it also has some drawbacks. First, the vibration generated when the train runs on the track can be transmitted to the mounting base through the sleepers, causing the connection between the screw and nut to loosen. Therefore, workers need to frequently check and reinforce the connection. Second, urban rail tracks are laid underground, and the underground environment is relatively humid, which can easily lead to corrosion of the screw and nut, thereby reducing the tightness of the screw and nut and making disassembly more difficult.

Six retaining slots are opened on the inner wall of the circular groove, and the retaining slots are adapted to the retaining plate.

[0009] Furthermore: the adsorption mechanism includes a sealing cylinder and a threaded sleeve. The sealing cylinder is fixedly installed at the bottom of the mounting plate, and a suction cup is fixedly installed at the bottom of the sealing cylinder.

Moving rods are fixedly installed on the opposite side of the two sliding sleeves. Pressure rings are fixedly installed on the opposite end of the two moving rods. The pressure rings are adapted to the suction cup. A pressure platform is fixedly installed on the top of the pressure ring. The second connecting rod is used in conjunction with the pressure platform.

[0012] Furthermore: two drive pulleys are fixedly sleeved on the outer side of the output shaft of the drive motor, and driven pulleys are fixedly sleeved on the outer side of the two threaded sleeves. The drive pulleys and driven pulleys are connected by the same belt. The two second insulating covers are provided with second through slots on opposite sides.

[0016] The beneficial effects of this invention are as follows: By setting up a clamping mechanism and a suction mechanism, the power supply rail is quickly and firmly fixed to the sleeper, preventing it from loosening or shifting during operation. At the same time, the connection strength between the power supply rail and the sleeper is greatly enhanced, thus providing better fixing force and stability for the power supply rail. Moreover, compared with using screws and nuts to fix the power supply rail, it is more durable and stable and will not loosen due to vibration during track operation. Furthermore, the suction cup effectively reduces the vibration and noise of the power supply rail during operation. Attached Figure Description

A retaining plate 706 is slidably connected within the slide rails 705. A limiting rod 707 is fixedly installed on the bottom of the retaining plate 706. A first through groove 708 is opened at the bottom of the rotating plate 704. The limiting rod 707 is slidably connected within the first through groove 708. A limiting groove 709, identical to the first through groove 708, is fixedly installed at the bottom of the fixed plate 703. The top end of the limiting rod 707 penetrates the retaining plate 706 and extends into the limiting groove 709. The top of the base plate 2 is opened... A circular groove 710 is provided, the diameter of which matches the fixed plate 703 and the rotating plate 704. Six slots 711 are provided on the inner wall of the circular groove 710. The slots 711 are adapted to the plate 706. The plate 706 can be supported and limited by the slide rail 705. The output shaft of the drive motor 701 can rotate the rotating plate 704. When the rotating plate 704 rotates, it will move the corresponding limit rod 906 through the six first through grooves 708 to slide along the trajectory of the first through grooves 708, thereby driving the plate 706 to slide in the slide rail 705 until it extends.

[0023] See Figure 1 , 2 As shown in Figures 3, 4, 6, and 8, in this embodiment, the adsorption mechanism 8 includes a sealing cylinder 801 and a threaded sleeve 802. The sealing cylinder 801 is fixedly installed at the bottom of the mounting plate 1, and a suction cup 803 is fixedly installed at the bottom of the sealing cylinder 801.

The sealing disc 805 and the inner wall of the sealing cylinder 801 are interference-fitted. The mounting plate 1 can support the threaded sleeve 802. See Figure 2 , 3 As shown in Figures 4, 6, and 8, in this embodiment, a connecting rod 806 is fixedly installed at the top of the screw 804, a first hinge seat 807 is fixedly installed at the bottom of the connecting rod 806, a first connecting rod 808 is hinged to the first hinge seat 807, a second hinge seat 809 is hinged to the bottom of the first connecting rod 808, a third hinge seat 810 is fixedly installed at the bottom of the mounting plate 1, a second connecting rod 811 is hinged to the third hinge seat 810, and the bottom of the second hinge seat 809 is fixedly connected to the second connecting rod 811.

[0024] See Figure 1 , 2 As shown in Figures 3, 4, 6, and 8, in this embodiment, two guide rods 812 are fixedly installed between the mounting plate 1 and the base plate 2. A sliding sleeve 813 is slidably connected to the outer side of the guide rods 812. A moving rod 814 is fixedly installed on the side of each of the two sliding sleeves 813 that is far apart from each other. A pressure ring 815 is fixedly installed on the end of each of the two moving rods 814 that is far apart from each other. The pressure ring 815 is adapted to the suction cup 803. A pressure platform 816 is fixedly installed on the top of the pressure ring 815. The second connecting rod 811 works in conjunction with the pressure platform 816. By setting the guide rods 812, the sliding sleeves 813, and the moving rods 814, the pressure ring 815 can be limited, preventing the pressure ring 815 from shifting when pressed downwards. By setting the pressure ring 815, the suction cup 803 and the rubber plate 821 can adhere more tightly during adsorption, thereby greatly improving the adsorption tightness between the suction cup 803 and the rubber plate 821.

[0025] See Figure 1 , 2 As shown in Figures 3 and 4, in this embodiment, two drive pulleys 817 are fixedly sleeved on the outer side of the output shaft of the drive motor 701, and driven pulleys 818 are fixedly sleeved on the outer side of the two threaded sleeves 802. The drive pulleys 817 and driven pulleys 818 are connected by the same belt 819. The two second insulating covers 4 are provided with second through slots 820 on opposite sides. The two connecting rods 806 are slidably connected to the corresponding second through slots 820. Two rubber plates 821 are fixedly installed on the top of the base plate 2. The rubber plates 821 are symmetrically arranged. The suction cup 803 and the rubber plates 821 are connected by a suction cup. The connecting rod 806 is slidably connected to the second through groove 820, which can limit the screw 804. The output shaft of the drive motor 701 rotates, which drives the two drive pulleys 817 to rotate. The rotation of the drive pulleys 817 drives the driven pulley 818 to rotate through the belt 819, which in turn drives the two second belt pulleys 819 to rotate, and then drives the two threaded sleeves 802 to rotate simultaneously. The rubber plate 821 helps the suction cup 803 to better adsorb, and the rubber plate 821 has good insulation properties and high temperature and low temperature resistance.

[0026] See Figure 1 , 2As shown in Figures 3 and 4, in this embodiment, the positioning mechanism 9 includes two support plates 901. The two support plates 901 are fixedly installed on the top of the two second insulating covers 4 respectively. The support plates 901 are symmetrically arranged. A pulley 902 is fixedly installed on the side of the two support plates 901 that is far apart from each other. A nylon rope 903 is wound around the outside of the pulley 902. The bottom ends of the two nylon ropes 903 pass through the corresponding second insulating cover 4 and extend into its interior. The bottom ends of the two nylon ropes 903 are fixedly connected to the corresponding screws 804 respectively. The ends of the two nylon ropes 903 that are close to each other pass through the inner walls of the left and right sides of the U-shaped plate 5 respectively and are fixedly connected to the corresponding positioning plates 6. The second insulating cover 4 can support the support plate 901.

[0027] See Figure 1 , 2 As shown in Figures 3 and 4, in this embodiment, a collar 904 is fixedly sleeved on the outer side of the nylon rope 903. The same spring 905 is fixedly installed between the collar 904 and the support plate 901. The two springs 905 are symmetrically arranged. Two round rods 906 are fixedly installed on the opposite side of the two positioning plates 6. The round rods 906 pass through the U-shaped plate 5 and are slidably connected to it. By setting the round rods 906, the positioning plates 6 can be limited to prevent them from shifting during movement.

[0028] See Figure 1 As shown in this embodiment, the top of the base plate 2 is provided with four mounting holes 10, which are symmetrically arranged. By providing mounting holes 10, the base plate 2 can be easily fixed to the top of the sleeper.

[0029] The operating principle of the present invention is described as follows: First, the base plate 2 is installed on the top of the sleeper of the track through the mounting hole 10. Then, the fixing plate 703 and the circular plate are inserted into the circular groove 710, while the suction cup 803 is attached to the rubber plate 821. Then, the power supply rail is suspended between the two positioning plates 6. Next, the drive motor 701 is started. The output shaft of the drive motor 701 rotates, driving the rotating plate 704 to rotate. When the rotating plate 704 rotates, it will move the corresponding limit rod 707 through the six first through grooves 708 to slide along the trajectory of the first through grooves 708, thereby driving the clamping plate. 706 slides within the slide rail 705 until it extends, causing all six clamping plates 706 to open and engage with their corresponding slots 711, thus initially fixing the mounting plate 1. Simultaneously, the output shaft of the drive motor 701 rotates, driving two drive pulleys 817. The rotation of the drive pulleys 817, via belts 819, drives the driven pulley 818, which in turn drives the two second belt pulleys 819. This, in turn, drives the two threaded sleeves 802 to rotate simultaneously, causing the two screws 804 to move the corresponding sealing plates upwards under the limiting action of the corresponding connecting rods 806, thus lifting the suction cup. Air is extracted between suction cup 803 and rubber plate 821, creating a negative pressure between their contact surfaces. This allows suction cup 803 to firmly adhere to rubber plate 821. Simultaneously, as screw 804 moves upward, it drives connecting rod 806 upward, which in turn moves first hinge seat 807 upward. The upward movement of first hinge seat 807, via first connecting rod 808, drives second hinge seat 809 upward. This, in turn, causes the left end of second connecting rod 811 to lift upward, using its hinge point with third hinge seat 810 as a fulcrum. Simultaneously, the right end of second connecting rod 811... The downward pressing of the end presses down on the pressure table 816, causing the pressure ring 815 to press down on the suction cup 803, thereby making the suction cup 803 and the rubber plate 821 adhere more tightly during adsorption, which can greatly improve the adsorption tightness between the suction cup 803 and the rubber plate 821. At the same time, as the two screws 804 move upward, they will release the tension of the two nylon ropes 903. The spring 905 will release its elastic potential energy as the nylon ropes 903 relax, which can drive the two collars 904 to move closer to each other, and then drive the two positioning plates 6 to move closer to each other, supporting and positioning the power supply rail.

[0030] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment without departing from the spirit of this embodiment and the scope of protection of the claims, and all of these forms are within the protection scope of this embodiment.
