Description

Technical Field

[0001] The utility model belongs to a rail transportation auxiliary device, in particular to a side-contact adjustable lengthened insulating support device. Background Art

[0002] The contact rail is a power supply device used in light rail or railway systems. In urban rail transit, especially in maglev trains and straddle-type monorail systems, rigid contact rails arranged along the line are used to provide mobile power to the train through on-board current collectors. The installation accuracy of the contact rail, especially the smoothness accuracy, has a significant impact on the current collection quality of the current collector. To ensure the high requirements for the installation position of the contact rail for current collection quality, existing insulating support devices can already adjust the swing and height difference simultaneously. However, in actual use, it was found that the actual position of some installation rails or embedded parts (such as grooves, embedded sleeves, etc.) is lower than the theoretical position, resulting in construction errors. When ordinary mounting supports are installed to the extreme position, they still cannot meet the installation position size requirements. When the installation height difference exceeds the groove adjustment range, ordinary insulating supports can no longer meet the installation requirements. Utility Model Content

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a side-contact adjustable lengthened insulating support device that improves construction and installation accuracy and reduces construction costs.

[0004] Technical solution: The utility model describes a side-contact adjustable and elongated insulating support device, comprising a mounting base, an adjustment frame and an insulator, wherein the insulator is connected to the adjustment frame via an angle adjustment mechanism; the mounting base comprises a base plate, a first connecting plate, a second connecting plate and a baffle, a first connecting plate and a second connecting plate parallel to each other are arranged on the base plate, a baffle is arranged between the first connecting plate and the second connecting plate, a U-shaped notch cooperating with the adjustment frame is arranged on the baffle, a plurality of groups of guide long holes are arranged on the first connecting plate and the second connecting plate, and the adjustment frame slides along the guide long holes via bolts; a pad is arranged on at least one surface where the adjustment frame is connected to the angle adjustment mechanism; the adjustment frame and the pad are connected via fasteners and the angle adjustment mechanism, and a shaft sleeve is arranged at the connection between the fasteners, the angle adjustment mechanism and the pad.

[0005] Furthermore, the first connecting plate and the second connecting plate are both trapezoidal plates.

[0006] Furthermore, the adjustment frame is a hollow frame structure, and arc holes, round holes and a rotating hole are symmetrically arranged on one group of opposite surfaces of the adjustment frame, and waist-shaped holes are symmetrically arranged on another group of opposite surfaces.

[0007] Furthermore, wing plates are provided at both ends of one surface of the adjustment frame, and a positioning plate is provided inside the adjustment frame.

[0008] Furthermore, the angle adjustment mechanism includes a double-pronged bolt and a swing block, with both ends of the swing block connected to the double-pronged bolt. One end of the double-pronged bolt is mounted on the adjustment frame via a hexagonal flange nut, while the other end passes through a backing plate and is threadedly fixed to the baffle. Tightening or locking the hexagonal flange locknuts on both sides adjusts the insulator's swing angle.

[0009] Furthermore, a swing block connecting hole 1, a swing block rotation hole, and a swing block connecting hole 2 are provided on the swing block. The swing block connecting hole 1 and the swing block connecting hole 2 are connected to the double fork bolt through a flat head retaining ring and an open retaining ring, and the swing block rotation hole is connected to the adjustment frame through a cylindrical pin.

[0010] The insulator further comprises a shed, a mounting platform, and a connecting portion. One end of the shed is connected to the mounting platform, and the other end is connected to the connecting portion. The mounting platform is fixedly connected to the claw, and a shock-absorbing pad is provided slightly above the center of the mounting platform. The connecting portion is provided with an adjustment hole and a second rotation hole. The adjustment hole is connected to the swing block rotation hole on the swing block via a cylindrical pin, and the second rotation hole is connected to the first rotation hole on the adjustment frame via a bolt fastener.

[0011] Working Principle: Loosening the nuts of the fasteners allows the entire adjustment frame to slide along the long guide holes. The wing plates on the adjustment frame ensure vertical movement, thus achieving height adjustment requirements. When the height is adjusted to the desired position, tighten the hexagonal nuts of the fasteners to secure the current position. The swing block cooperates with the double fork bolts arranged vertically, and the locknuts of the double fork bolts are screwed up and down to achieve up and down swing adjustment. After the up and down swing adjustment, the frame is securely fixed, achieving adjustment of the contact rail inclination angle. This not only facilitates adjustment and allows for a large adjustment range, but also prevents loosening during line operation. Secure the fasteners to ensure structural stability during shaking.

[0012] Beneficial effects: Compared with the prior art, the present invention has the following characteristics:

[0013] 1. The two adjustment methods are combined to achieve high adjustment accuracy, which helps to improve construction and installation accuracy, reduce construction costs, and solve the problem that the existing insulation support device cannot meet the installation position size requirements;

[0014] 2. The holes for fixing the base to the foundation are located below the structure, and the long waist-shaped holes for matching with the adjustment frame are located above the structure to ensure that the installation center axis of the insulating support forms a distance with the center axis of the contact rail installation and telescopic adjustment;

[0015] 3. The fixed base and adjustment frame are made of customized profiles, and other components adopt modular design and mostly use standard parts, which are easy to produce, assemble and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figures 1 to 4 The mounting base 1 of the side-contact adjustable extended insulating support device is slidably connected to the adjusting frame 2 via a bolt 5. The insulator 3 is hinged on the adjusting frame 2, and the insulator 3 is connected to the adjusting frame 2 via an angle adjustment mechanism 4 to adjust the inclination angle of the contact rail. The bolt 5 is a hexagonal flange face locknut M12. A pair of nylon claws 10 are installed on the insulator 3 via bolts and washers to ensure the installation and fixation of the I-shaped contact rail. A pad 6 is provided on the lower surface where the adjusting frame 2 is connected to the angle adjustment mechanism 4. The adjusting frame 2 and the pad 6 are fitted together and pass through the fastener 8 and the angle adjustment mechanism 4. A shaft sleeve 7 is provided at the connection between the fastener 8, the angle adjustment mechanism 4 and the pad 6. The width of the shaft sleeve 7 is slightly smaller than the width of the pad 6. The fastener 8 is passed through the circular hole 206 of the adjusting frame 2 and clamped on the positioning plate 11.

[0028] like Figures 4 to 8The angle adjustment mechanism 4 includes a double-pronged bolt 401 and a swing block 402. Both ends of the swing block 402 are connected to the double-pronged bolt 401. The first and second swing block connection holes 4021 and 4023 on either side of the swing block 402 are connected to the double-pronged bolt 401 via pins. One end of the threaded portion of the double-pronged bolt 401 extends through the waist-shaped hole 204 on the top surface of the adjustment frame 2 and is secured to the adjustment frame 2 using a hexagonal flange nut. The other end of the double-pronged bolt 401 passes through the waist-shaped hole 204 on the bottom surface of the adjustment frame 2, is then fitted with a bushing 7, and then extends through the U-shaped notch 105 of the baffle 104. The protruding portion passes through the backing plate 6 and is secured using a hexagonal flange nut. When the hexagonal flange nut on one side of the adjustment frame 2 is tightened and the other side is loosened, the double-pronged bolt 401 causes the swing block 402 to swing toward the tightened side, causing the insulator 3 to swing accordingly. This achieves the desired contact rail angle adjustment. The swing block 402 is provided with a swing block connecting hole 1 4021, a swing block rotation hole 4022, and a swing block connecting hole 2 4023. The swing block connecting hole 1 4021 and the swing block connecting hole 2 4023 are connected to the double fork head bolt 401 through a pin shaft, and the swing block rotation hole 4022 is connected to the adjustment frame 2 through a cylindrical pin 9.

[0029] like Figure 8 The mounting base 1 includes a base plate 101, a first connecting plate 102, a second connecting plate 103, and a baffle 104. The base plate 101 is provided with a first connecting plate 102 and a second connecting plate 103 that are parallel to each other. When the height difference between the groove and the contact rail is appropriate at the construction site, an extended insulating support is selected. During installation, the mounting hole 1011 on the base plate 101 is positioned downward and is fixed by a T-bolt in the groove. Due to the lengthening of the base plate 101, the insulating support is raised overall, which is more suitable when the height difference between the groove position and the contact rail is relatively large. A baffle 104 is provided between the first connecting plate 102 and the second connecting plate 103, and a U-shaped notch 105 that cooperates with the adjustment frame 2 is provided on the baffle 104. Two sets of guide long holes 106 are provided on the first connecting plate 102 and the second connecting plate 103. The first connecting plate 102 and the second connecting plate 103 are both trapezoidal plates, with a large bevel cut at the lower part and symmetrical matching grooves. The adjustment frame 2 is connected to the mounting base 1 via two bolts 5 through the guide slot 106, allowing the adjustment frame 2 to slide through the guide slot 106 to achieve height compensation. A baffle 104 is welded to the mounting base 1, fitting against one end of the adjustment frame 2 to provide positioning and assist in securing the double-pronged bolts 401. The mounting base 1 is machined from profiles and adopts an elongated structure. The mounting hole 1011, which is fixed to the foundation, is located below the structure, while the long waist-shaped guide slot 106, which cooperates with the adjustment frame 2, is located above the structure to ensure that the installation center axis of the insulating support is spaced apart from the center axis of the contact rail for installation and telescopic adjustment.

[0030] like Figures 9-10The adjustment frame 2 is a hollow frame structure. A set of opposing surfaces of the adjustment frame 2 is symmetrically provided with arcuate holes 201, circular holes 202, and a first rotation hole 203. Each surface has one arcuate hole 201, two circular holes 202, and one first rotation hole 203. The other set of opposing surfaces is symmetrically provided with waist-shaped holes 204. Wings 205 are provided at both ends of one surface of the adjustment frame 2. A positioning plate 11 is included within the adjustment frame 2 to facilitate tightening the nuts. After height and angle adjustment are completed, tighten the hexagonal nuts of the fasteners 8.

[0031] like Figure 11 The insulator 3 comprises a shed 301, a mounting platform 302, and a connecting portion 303. The shed 301 is connected to the mounting platform 302 at one end and to the connecting portion 303 at the other. The rectangular mounting platform 302 has threaded holes 3021, to which a pair of nylon claws 10 are bolted. Tightening the bolts firmly presses the I-shaped contact rail against the mounting platform 302. To mitigate vibrations caused by the current collector passing over the contact rail, a shock-absorbing pad 304 is installed slightly above the center of the mounting platform 302. The pad is attached to the rectangular mounting platform 302 using hexagon socket head cap screws. The top of the pad contacts the bottom of the contact rail, absorbing any vibrations. The pad ensures smooth passage of the current collector. The arc-shaped fork-shaped structure of the connecting portion 303 is machined with an adjustment hole 3031 and a second rotation hole 3032. Rotation hole 2032 is connected to rotation hole 103 on adjustment frame 2 via bolts, ensuring left and right swing of insulator 3. Adjustment hole 3031 is also connected to swing block rotation hole 4022 on swing block 402 via cylindrical pin 9. Cylindrical pin 9 extends outward to contact arcuate hole 201 on adjustment frame 2, limiting the swing range of swing block 402 during angle adjustment.
