Description

Technical Field

[0001] The present invention belongs to the technical field of rail transportation, and in particular relates to a contact rail insulating support device, a shock-absorbing support device, and a detachable support device. Background Art

[0002] The aerial rail train is a city rapid transit bus and a suspended rail transportation system, including track piers, track beams, aerial rail trains and vehicle bogies. The vehicle bogies are set on the upper part of the vehicle and are used to drive the aerial rail train to move longitudinally along the track beams. The aerial rail train, that is, the suspended sky rail, is different from the subway and tram. Its tracks are set above, and it can make use of urban greening to build tracks and near-ground spaces such as under bridges. The construction cost is low and the construction period is short. Construction in congested areas can effectively alleviate traffic pressure.

[0003] The contact rail power supply system is an important power supply method for urban rail transit. The contact rail is a device that transmits electrical energy to the electric traction vehicles of the rail transit system. In the suspended sky train system, contact rail power supply is adopted. The contact rail is set on the side wall of the box girder track. The track beam and the contact rail are separated by an insulating support device to ensure the safety of the system power supply. However, the support devices currently used are made of fiberglass or steel insulation, which are rigid structures. Due to factors such as manufacturing and installation, a gap of 0.1 mm to 1 mm is inevitably left between the assembled insulating support device and the power supply contact rail. There is a pressure of 100-130N between the power receiving shoe and the power supply contact rail. When the sky train receives power through the power receiving shoe and the power supply contact rail while traveling, it actually causes great vibration, and even causes noise that can be transmitted for hundreds of meters. Severe vibration can cause damage to the insulating support device and the contact rail. At the same time, the damaged part of the insulating support device can only be replaced after dismantling up to 30 meters of contact rail, which is inconvenient and time-consuming to repair.

[0048] In the present invention, the shock absorbing device cooperates with the insulating device to bear the power supply contact rail.

The multi-stage shock absorbing elastic component can be a plate-shaped, block-shaped, or cone-shaped multi-stage rubber component. That is, different rib-shaped drillings or bosses can be provided on the multi-stage shock absorbing elastic component to increase the deformation when subjected to force and ensure the shock absorption effect; between the end of the insulating device away from the power supply contact rail and the web of the track beam The distance between the insulating device and the web of the track beam is greater than the depth of the C-shaped groove of the power supply contact rail, that is, the lateral length of the connecting device arranged at the end of the insulating device away from the power supply contact rail is greater than the depth of the C-shaped groove of the power supply contact rail, or it is ensured that when a damaged insulating device in an assembled state needs to be removed, the distance between one end of the insulating device and the web of the track beam is sufficient to ensure that the connecting device can be movably removed relative to the fixing device, and then the insulating device is rotated to separate from the power supply contact rail for removal, thereby improving the practicality of the supporting device, achieving both vibration reduction and noise reduction during operation, and facilitating disassembly and maintenance.

[0049] The present invention is further described below with reference to the accompanying drawings and in combination with specific embodiments.

[0050] Refer to the attached Figure 1 and attached Figure 2 , Figure 1 This is a schematic diagram of the three-dimensional structure of the contact rail insulation support device of the present invention. Figure 2 yes Figure 1 The exploded view of the present invention provides a contact rail insulation support device, including a first shock absorbing member 1, an insulator 2, a connecting member 3, a spring washer 4, a double-headed screw 5, a track beam web 6, and a contact rail 7, wherein the contact rail 7 is a power supply system that acts on the power receiving shoes arranged on both sides of the sky train, and the side of the contact rail 7 away from the working surface is a C-shaped groove for connecting with the insulator 2; in the present invention, the insulating device is an insulator 2 made of ceramic material, which is used to isolate the contact rail 1 and the track beam web 6 to ensure the safety of the power supply system, wherein the left side of the insulator 2 It is engaged with the contact rail 1, and a first shock-absorbing member 1 for shock absorption is provided between the contact rail 7 and the insulator 2. In this embodiment, the first shock-absorbing member is a block-shaped rubber member. The left side of the rubber member is a plane that matches the C-shaped groove surface of the contact rail to ensure close contact with the contact rail after assembly. The right side of the rubber member is shaped to match the left groove of the insulator 2. A groove is provided in the middle of the upper and lower end surfaces of the rubber member, and the upper and lower grooves are used to achieve engagement with the left end of the insulator to ensure a fixed connection between the rubber member and the insulator.

[0051] Continue to refer to the attached Figure 2 , the right end of the insulator is provided with a connecting member 3 of the same material as the insulator. In this embodiment, the connecting member is made of ceramic. The connecting device includes a connecting portion and a fixing portion, wherein the connecting portion is an open ring and the fixing portion is a bayonet. The open ring and the bayonet are detachably connected. In the present invention, the bayonet is not shown in the figure. In the assembled state, the connecting member is arranged on the right side of the insulator, and the left side of the connecting member is tightly fitted with the right side of the insulator to support the insulator to carry the contact rail. The open ring is clamped to the fixing device by the bayonet. When the insulating device is damaged or needs to be repaired, it is generally repaired by removing the long The corresponding insulating device can only be disassembled after the power supply contact rail reaches 30 meters. However, through the connecting member 3 provided in the present invention, the open ring, i.e., the connecting member 3, is disassembled by removing the latch, and the double-headed screw is removed from the outside of the web of the track beam to ensure the mobility of the insulating device, and then the insulating device is rotated a certain angle to separate it from the power supply contact rail, and then the lateral movement of the insulating device is achieved through the space left by the disassembled connecting member, and then the insulating device that needs to be inspected or replaced is taken out from between the power supply contact rail and the web of the track beam, thereby realizing the flexible disassembly of the insulating device by the contact rail insulating support device.

[0052] A spring washer 4 for protecting the insulator is also provided between the connecting member 3 and the web 6 of the track beam. During the operation of the insulating support device, the train's power shoe is pressed and contacted with the outer side of the contact rail, and then the connecting member and the web of the track beam are in hard collision contact, which will cause damage to the connecting member. In severe cases, it will cause damage to the insulator, affecting the insulation effect of the support device and not utilizing the power supply safety of the system. Therefore, the setting of the spring washer also effectively reduces the hard collision impact between the insulator, the connecting member and the web of the track beam, and improves the service life; in this embodiment, there is one elastic washer. It is understood by those skilled in the art that this scheme does not limit the scope of protection of the present invention. The elastic washers may be one or more and may be circular, closed or open, so they will not be described one by one here.

[0053] The insulator, the connecting member and the elastic washer are coaxially arranged and fixedly connected to the web 6 of the rail beam by a stud screw 5, that is, a threaded hole is opened at the right end of the insulating device, and the stud screw is threadedly connected to the insulating device. In the present invention, the length of the thread opened on the right side of the insulator is less than the length of the insulator. Preferably, the length of the thread opened is less than half of the length of the insulator to ensure the insulation effect, that is, when the stud screw can fix the insulator, the length of the stud screw fixed to the inside of the insulator should ensure its insulation effect.

[0054] Preferably, the connecting member is an open member for easy disassembly.

[0055] Preferably, a clamping device for clamping the connecting member is provided at the open end of the connecting member to ensure that it is fastened to the double-start screw after assembly.

[0056] Preferably, the first shock-absorbing member may be a multi-stage shock-absorbing elastic member, which is fixed by snapping or bonding with the groove; or, the multi-stage shock-absorbing elastic member includes a first shock-absorbing member, a second shock-absorbing member and a third shock-absorbing member, wherein the first shock-absorbing member, the second shock-absorbing member and the third shock-absorbing member are all in contact and connected, the first shock-absorbing member and the second shock-absorbing member may be arranged in the groove of the insulating device, and the groove is not connected to the threaded hole at the other end, and the third shock-absorbing member is arranged on the outside of the first shock-absorbing member and the second shock-absorbing member, and is used during the assembly process. Close contact with the power supply contact rail reduces the gap between the power supply contact rail and the insulating device, thereby achieving shock absorption and noise reduction; the first shock absorption component and the second shock absorption component are springs with different elasticity, or rubber components with different elasticity, and the third shock absorption component is an elastic gasket or a rubber gasket. The first shock absorption component, the second shock absorption component, and the third shock absorption component are elastic elements with different elasticity grades, so that when the power supply contact rail is impacted by the train power shoe during operation, the shock absorption device can provide multi-level shock absorption and buffering, thereby protecting the insulating device while reducing shock and noise, and improving the service life of the insulator.

[0057] Furthermore, a plurality of grooves may be provided at one end of the insulator close to the contact rail for fixing the first shock-absorbing member, that is, one or more first shock-absorbing members may be provided according to actual needs. In the present invention, the number and shape of the first shock-absorbing members do not limit the scope of protection of the present invention.

[0058] Furthermore, in the contact rail area between the insulator and the power supply contact rail, a rubber pad is provided to protect the C-shaped groove of the power supply contact rail and the end of the insulator. When the insulator is fixedly supporting the power supply contact rail after assembly, the hard collision between the two is reduced, as well as the hard collision after being impacted by external force, thereby protecting the insulator and the power supply contact rail; the rubber pad can be provided in the upper and lower contact surface areas where the insulator contacts the power supply contact rail, or it can be bonded and provided on the peripheral side of the load-bearing area between the insulator and the power supply contact rail. It is known to those skilled in the art that as long as the purpose of reducing the hard collision when the insulator contacts the power supply contact rail can be achieved, any setting is acceptable. This embodiment does not limit the scope of protection of the present invention, so it will not be described one by one here.

[0059] During the assembly process of the contact rail insulation support device of the present invention, the insulator, connecting member and spring washer are fixed by the double-headed screw and the threaded connection on the right side of the insulator, and the first shock-absorbing member is fixed by the groove set on the left end face of the insulator. Since the first shock-absorbing member is an elastic member, the contact rail insulation support device composed of the first shock-absorbing member, insulator, connecting member, spring washer and double-headed screw releases its own elasticity after being assembled with the contact rail, thereby ensuring close contact between the insulator and the contact rail, ensuring that when the train passes through the side power shoe and the contact rail under pressure during operation, the hard collision between the contact rail and the insulator is effectively reduced, and vibration and noise pollution are reduced; when the insulator in the contact rail insulation support device is damaged and needs to be repaired, During replacement, in the prior art, the corresponding contact rail needs to be removed before the corresponding insulator to be replaced can be removed, which brings great inconvenience to maintenance personnel and wastes time. However, in the present invention, a connecting member made of the same material as the insulator is provided, so that when the insulator is damaged, the insulator to be repaired can be removed without removing the corresponding contact rail. The specific method is as follows: 1. If a clamping device is provided on the connecting member, the clamping device is removed to make the connecting member movable relative to the double-headed screw; 2. Remove the double-headed screw and remove it from the outer side of the web of the track beam or away from the end of the threaded hole of the insulator by rotating it; 3. Rotate the insulator engaged in the C-shaped groove of the contact rail by a certain angle to remove the insulator from the C-shaped groove of the contact rail.

[0060] Furthermore, the connecting device can also be a nut, that is, in the assembled state, the nuts are tightened simultaneously on the left and right sides of the double-headed screw passing through the web of the track beam to ensure that the insulating device connected to the double-headed screw is fixed relative to the web of the track beam and does not slide. When the insulating device in the assembled state needs to be disassembled, the outer nut of the web of the track beam is unscrewed, the inner nut of the web of the track beam is loosened, and the double-headed screw is rotated to disengage the insulating device. The insulating device is rotated to a certain angle to be separated from the power supply contact rail, thereby realizing lateral movement of the insulating device, and then the insulating device is taken out to realize rapid disassembly of the support device in the assembled state.

[0061] A shock-absorbing support device is used for the installation and support of a power supply contact rail, comprising an insulating device, a fixing device and a shock-absorbing device; the insulating device and the fixing device are detachably connected; the shock-absorbing device is arranged at the end of the insulating device that contacts the power supply contact rail; in the assembled state, the insulating device is fixedly mounted on the web of the track beam by the fixing device, and the insulating device is pressed against the power supply contact rail by the shock-absorbing device, thereby effectively achieving shock absorption and noise reduction during the operation of the power supply contact rail.

In this way, in the assembled state, the insulating device can be flexibly disassembled without disassembling the power supply contact rail of up to 30 meters, thereby reducing workload and improving the practicality of the support device.
