Description
Technical Field
[0001] This utility model belongs to the technical field of rail pipe opening protection, and specifically discloses a rail pipe opening protection device for the four electrical interfaces of high-speed railway. Background Technology
[0002] High-speed railway traction power supply (electrification), along with communication, signaling, and power systems, are collectively known as the "four electrical systems." The interface engineering for these four electrical systems refers to the pre-construction and coordination projects between the two major disciplines: pre-station and post-station. High-speed railways are a systematic project involving multiple parties, multi-disciplinary coordination, multi-directional advancement, and cross-operation of multiple trades. The four electrical systems and civil engineering involve complex and intricate interface engineering, such as: integrated grounding construction for bridges, tunnels, and roadbeds; cable laying for communication, signaling, power, and electrification systems on bridges; pre-embedding of communication, signaling, and power lines in tunnels and roadbeds; pre-embedding of various types of contact wire channels in tunnels; construction of contact wire foundations and guy wire foundations for bridge beams; construction of station track crossings and integrated grounding projects; construction of contact wire support foundations and anchor guy wire foundations in the roadbed; and prefabrication and laying of cable troughs in the roadbed.
[0003] According to the construction sequence, railway electrification can only be carried out after the pre-station works are basically completed. Therefore, certain measures must be taken during the pre-station works to reserve working surfaces for the later electrification works, such as burying track pipes to reserve channels for the later electrification lines.
[0004] Because the construction period for the station pre-construction project is relatively long, failure to effectively protect the pipe openings of the track crossing pipes can easily lead to pipe blockage, which will have a significant impact on the subsequent track pipe laying construction. Utility Model Content
[0005] This utility model provides a protection device for the pipe opening of the four electrical interfaces of a high-speed railway, which can effectively protect the pipe opening.
[0006] The aforementioned high-speed railway four-electric interface rail pipe opening protection device includes a rubber sleeve, a fixing block, a connecting bend rod, and a traction hook; the rubber sleeve includes a circular top plate and an annular side plate set below the circular top plate, and multiple fixing blocks are set on the inner wall of the annular side plate; the connecting bend rod extends beyond the bottom end of the annular side plate, the end inside the rubber sleeve is connected to the bottom end of the fixing block, and the end outside the rubber sleeve is connected to the bottom end of the traction hook.
[0007] Preferably, in the rubber sleeve, a protective sponge is fixed on the inner wall of the circular top plate, and a protective pad is fixed on the inner wall of the annular side plate; the top end of the protective pad is connected to the protective sponge, and the bottom end is flush with the bottom end of the annular side plate; the protective pad is provided with an installation groove corresponding to the fixing block; the fixing block is installed in the installation groove, and its thickness is equal to the thickness of the protective pad.
[0008] Preferably, the outer wall of the rubber sleeve is coated with a waterproof membrane, and the waterproof membrane is coated with a corrosion-resistant coating.
[0009] Preferably, the waterproof membrane is made of acrylic waterproof coating, and the corrosion-resistant coating is made of polytetrafluoroethylene.
[0010] Preferably, the outer wall of the rubber sleeve is provided with an annular groove, and a fixing strap is wound inside the annular groove; the two ends of the fixing strap are tied or connected by a connector.
[0011] Preferably, the connector includes a connecting frame fixed to the first end of the fixing belt and a limiting block and a limiting hole disposed on the fixing belt; multiple limiting blocks and limiting holes are provided, the distance between two adjacent limiting blocks is equal to the distance between two adjacent limiting holes, and the limiting block is located between the limiting hole and the connecting frame; the second end of the fixing belt passes through the connecting frame and bends to fit the limiting hole over the limiting block.
[0012] Preferably, the towing hook is fitted with a removable protective shell.
[0013] Preferably, in the rubber sleeve, a limiting groove is provided on the outer wall of the annular side plate; a limiting groove is provided on each side of each traction hook; an arc-shaped plate is provided on the side wall of the protective shell facing the rubber sleeve, and a through hole corresponding to the traction hook is provided on the bottom plate; limiting sliders are fixed on both sides of the arc-shaped plate, and the limiting sliders are inserted into the limiting grooves along the axial direction of the rubber sleeve, and the arc-shaped plate fits against the annular side plate of the rubber sleeve.
[0014] Preferably, two sets of traction hooks are provided, symmetrically distributed around the central axis of the rubber sleeve.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. By placing the rubber sleeve over the opening of the rail pipe, the opening of the rail pipe can be sealed and protected, effectively protecting the opening of the rail pipe. The setting of the traction hook provides a force point for removing the rubber sleeve. Applying force to the traction hook causes the rubber sleeve to rise, which not only makes it easy to separate the rubber sleeve from the opening of the rail pipe, but also prevents the bottom of the rubber sleeve from being torn due to direct pulling, which would affect the next use, thus effectively extending the service life of the rubber sleeve.
[0017] 2. The protective pads and protective sponges on the inside of the rubber sleeve can buffer and protect the opening of the rail pipe, increasing the service life of the rail pipe opening. The waterproof membrane on the outside of the rubber sleeve has extensibility, elasticity, crack resistance, impermeability and weather resistance, which can prevent water from seeping into the interior of the rubber sleeve and affecting the rail pipe. The corrosion-resistant coating on the outside of the waterproof membrane can increase the service life of the rubber sleeve and prevent the rubber sleeve from being damaged by prolonged exposure to air.
[0018] 3. After installing the rubber sleeve, wrap the fixing strap around the outside of the rubber sleeve, and then fix both ends of the fixing strap so that the fixing strap is tightly wrapped around the outside of the rubber sleeve. This can prevent the rubber sleeve from accidentally coming off the rail pipe opening. The connection method of using a connecting frame, limiting hole and limiting block is more secure and prevents it from coming apart.
[0019] 4. The protective shell is installed on the outside of the towing hook through the limiting groove and the limiting slider to cover the towing hook. This not only protects the towing hook but also prevents the towing hook from accidentally injuring workers or other components. When it is necessary to remove the rubber sleeve, remove the protective shell from the outside of the towing hook before pulling the towing hook. Attached Figure Description

[0029] By placing the rubber sleeve 1 over the opening of the rail pipe, the opening of the rail pipe can be sealed and protected, effectively protecting the opening of the rail pipe. The setting of the traction hook 5 provides a force point for removing the rubber sleeve. Applying force to the traction hook 5 causes the rubber sleeve 1 to rise, which not only makes it easy to separate the rubber sleeve 1 from the opening of the rail pipe, but also prevents the bottom end of the rubber sleeve 1 from being torn due to direct pulling, which would affect the next use, thus effectively extending the service life of the rubber sleeve 1.
[0030] Preferably, in the rubber sleeve 1, a protective sponge 9 is fixed on the inner wall of the circular top plate, and a protective pad 8 is fixed on the inner wall of the annular side plate; the top end of the protective pad 8 is connected to the protective sponge 9, and the bottom end is flush with the bottom end of the annular side plate; the protective pad 8 is provided with an installation groove corresponding to the fixing block 2; the fixing block 2 is installed in the installation groove, and its thickness is equal to the thickness of the protective pad 8.
[0031] The protective pad 8 and protective sponge 9 inside the rubber sleeve 1 can buffer and protect the opening of the rail pipe, increasing the service life of the rail pipe opening.
[0032] Preferably, the outer wall of the rubber sleeve 1 is coated with a waterproof membrane 15, and the waterproof membrane 15 is coated with a corrosion-resistant coating 14.
[0033] Preferably, the waterproof membrane 15 is made of acrylic waterproof coating, and the corrosion-resistant coating 14 is made of polytetrafluoroethylene.
[0034] The waterproof membrane 15 has extensibility, elasticity, crack resistance, impermeability and weather resistance, which can prevent water from seeping into the interior of the rubber sleeve 1 and affecting the rail pipe. The corrosion-resistant coating 14 on the outside of the rubber sleeve 1 can increase the service life of the rubber sleeve 1 and prevent the rubber sleeve 1 from being damaged by prolonged exposure to air.
[0035] Preferably, the outer wall of the rubber sleeve 1 is provided with an annular groove 6, and a fixing strap 7 is wound inside the annular groove 6; the two ends of the fixing strap 7 are tied or connected by a connector.
[0036] After installing the rubber sleeve 1, wrap the fixing strap 7 around the outside of the rubber sleeve 1, and then fix both ends of the fixing strap 7 so that the fixing strap 7 is tightly wrapped around the outside of the rubber sleeve 1, which can prevent the rubber sleeve 1 from accidentally coming off the rail pipe opening.
[0037] Since binding can easily cause the straps to come apart, this embodiment preferably uses a connector. The connector includes a connecting frame 17 fixed to the first end of the fixing strap 7, and a limiting block 10 and a limiting hole 11 disposed on the fixing strap 7. Multiple limiting blocks 10 and limiting holes 11 are provided, and the distance between two adjacent limiting blocks 10 is equal to the distance between two adjacent limiting holes 11. The limiting block 10 is located between the limiting hole 11 and the connecting frame 17.

[0038] After installing the rubber sleeve 1, wrap the fixing strap 7 around the outside of the rubber sleeve 1. Then, pass the second end of the fixing strap 7 through the connecting frame 17 and bend it. Pull the second end of the fixing strap 7 to make the fixing strap 7 tightly wrap around the outside of the rubber sleeve 1. After wrapping, insert the limiting block 10 into the limiting hole 11 to limit and fix the fixing strap 7.
[0039] Preferably, the towing hook 5 is fitted with a detachable protective shell 4.
[0040] Preferably, in the rubber sleeve 1, a limiting groove 13 is provided on the outer wall of the annular side plate; a limiting groove 13 is provided on each side of each traction hook 5; an arc plate 12 is provided on the side wall of the protective shell 4 facing the rubber sleeve 1, and a through hole corresponding to the traction hook 5 is provided on the bottom plate; limiting sliders 16 are fixed on both sides of the arc plate 12, and the limiting sliders 16 are inserted downward along the axial direction of the rubber sleeve 1 into the limiting groove 13, and the arc plate 12 fits against the annular side plate of the rubber sleeve 1.
[0041] Preferably, the traction hooks 5 are provided in two sets, symmetrically distributed around the central axis of the rubber sleeve 1.
[0042] The protective shell 4 is installed on the outside of the traction hook 5 through the limiting groove 13 and the limiting slider 16 to shield the traction hook 5. This not only protects the traction hook 5 but also prevents the traction hook 5 from accidentally injuring workers or other components. When it is necessary to remove the rubber sleeve 1 from the outside of the rail pipe opening, the protective shell 4 is removed from the outside of the traction hook 5, and then the traction hook 5 is pulled. The traction hook 5 raises both sides of the rubber sleeve 1 through the connecting bent rod 3 and the fixing block 2. This not only makes it easy to remove the rubber sleeve 1 from the outside of the pipe opening but also prevents the rubber sleeve 1 from being damaged and affecting the next use.
