Description

TECHNICAL FIELD

[0001] The present application belongs to the field of railway maintenance equipment, and specifically relates to a rail segment clamping adapter and a carrying device comprising the same. BACKGROUND

[0002] In the daily operation of railway maintenance sections, welding and carrying of rails are important links to ensure the safety of railway operation. Efficient and safe equipment is needed for the carrying and positioning of rail segments, but the existing technology has certain deficiencies in operability, flexibility and safety. For example, CN108313611A discloses a manual rail carrying device, which realizes manual carrying of rails by setting a support at both ends of the rail, which can be flipped by a lever mechanism using a reversed "U"-shaped bracket to lift the rail. However, this device still has problems such as insufficient adaptability, complex operation, low efficiency, etc., especially in high-density storage environments, where the operating space is limited, making it difficult to meet actual needs.

[0003] Common rail carrying tools may have the following problems during use:

[0004] Insufficient adaptability: existing equipment is difficult to adapt to different sizes and types of rails, especially in high-density storage environments, where the operating space is limited.

[0005] Complex operation: traditional equipment requires high manpower and needs multiple people to cooperate, resulting in low operation efficiency.

[0006] Safety hazards: some tools are not stable during clamping and moving the rail, which may cause the rail to fall off or scratch the surface of the rail.

[0007] High maintenance cost: complex mechanical structure and high frequency of use result in high equipment failure rate, increasing maintenance and replacement cost.

[0008] Therefore, there is an urgent need for a rail segment clamping and carrying device that is reasonably designed, easy to operate and safe and reliable to meet the actual needs of railway maintenance sections. INNOVATION CONTENT

[0009] A rail segment clamping adapter, comprising:

[0010] A clamping part for supporting the web of the rail;

[0011] An adapter part connected to one end of the clamping part on one side and used to connect a lifting and carrying component on the other side;

[0012] The clamping part includes clamping pieces arranged side by side, and at least one connecting plate arranged between the clamping pieces, the spacing between the clamping pieces is greater than the thickness of the web of the rail and less than the width of the rail head, and the connecting plate is connected to the clamping pieces on both sides in a "door" type.

[0013] The clamping mode of the adapter is that two straight clamping pieces pass through the sides of the rail waist of the rail, and the rail section is carried by lifting the adapter. The main support and limiting are performed by the clamping pieces. If the connecting plate is set too low, it is easy to act on the rail head and cause friction or scratch on the surface of the rail head. Therefore, the connecting plate needs to be set higher than the surface of the rail head. The connecting plate is used to relatively fix the positions of the two clamping pieces. Therefore, the connecting plate needs to be set close to the end. The front end of the clamping piece is fixedly connected with the adapter part.

[0014] The connecting plate can be segmented and set as multiple, or lengthened and reduced in quantity. A small number of short connecting plates are more conducive to observing the clamping condition.

[0015] The storage of the rail section is generally a multi-layer steel frame. The rails are arranged layer by layer with one end inward and the other end outward on the steel frame. The spacing between each rail is small. The clamping part is horizontally formed by two clamping rods with small spacing. The clamping part is inserted into the rail vertically and clamped to the rail. The horizontal space required for operation is very small. Therefore, the clamping part can adapt to the storage and taking of a large number of rails with high density.

[0016] Further, the clamping part includes two parallel clamping rods, that is, the clamping piece is a clamping rod. A door-shaped connecting plate is arranged above the clamping rod to connect the two clamping rods.

[0017] Further, the connection between the connecting plate and the clamping rod is perpendicular to the clamping rod, so as to avoid damage caused by the contact between the sidewall of the connecting plate and the rail head during clamping. The distance between the bottom surface of the upper part of the connecting plate and the height of the clamping rod is greater than the thickness of the rail head.

[0018] Further, the adapter part includes a support plate perpendicular to the front end of the clamping piece, a traction seat, and a lifting guide wheel arranged on the support plate. The traction seat is used to lift the adapter part to realize the taking of the rail. The guide wheel can constrain the direction.

[0019] Further, the traction seat is arranged at the top of the support plate. If there are multiple traction seats, the traction seats are symmetrically arranged. The symmetrically arranged traction seats can make the lifting of the adapter part more balanced and stable.

[0020] The lifting guide wheels are arranged on both sides of the support plate. At least two lifting guide wheels are arranged in the vertical direction on each side to better realize the direction constraint. The corresponding guide wheels on the left and right sides are located on the same horizontal plane and are balanced left and right when subjected to force.

[0021] The application also provides a carrying device including the adapter and a carrying device.

[0022] The carrying device includes a lifting guide rail matched with the guide wheel and a traction mechanism matched with the traction seat.

[0023] The traction mechanism includes a flexible transmission mechanism and a driving mechanism.

[0024] The flexible transmission mechanism comprises a combination of one or more flexible transmission members such as chain transmission, belt transmission, or steel wire rope and a transmission wheel matched therewith;

[0025] The driving mechanism is one of a hydraulic cylinder and / or a pneumatic cylinder, and / or one of a manual winch and an electric winch. The driving mechanism is matched with the transmission mechanism to realize the taking and placing of the steel rail.

[0026] Further, the device further comprises a rack, and the rack comprises at least two support rods parallel to the clamping member. Generally, only two support rods are needed to be arranged. After the steel rail is clamped, the whole center of mass is offset to the rear end of the device, so the support rods need to be extended to the end of the clamping rod, and the extension length is greater than the length of the clamping rod.

[0027] The front end of the support rod is connected through a support member, and the upper surface of the support member is a base. Two vertical lifting rails are arranged side by side on both sides of the base, and a guide wheel is located inside the lifting rail and can roll in the vertical direction.

[0028] The middle part or the part close to the middle part of the lifting rail on both sides of the rack is provided with an intermediate connecting member, and the intermediate connecting member extends outward. A handle is arranged below the intermediate connecting member, and the handle is symmetrically arranged left and right to facilitate the operation of the staff.

[0029] Further, the driving mode one is as follows:

[0030] The middle part of the base is provided with a first mounting seat, and the first mounting seat is used to arrange the cylinder end of the hydraulic cylinder or the pneumatic cylinder. The lifting direction of the hydraulic cylinder or the pneumatic cylinder is consistent with the direction of the lifting rail.

[0031] The top end of the piston end is provided with a lifting frame, and the lifting frame is provided with a transmission wheel, that is, a relatively labor-saving dynamic pulley mechanism. In order to improve the balance, the lifting frame can be arranged in a symmetrical manner about the center of the cylinder, and two transmission wheels are symmetrically arranged at both ends of the lifting frame. One end of the flexible transmission member is connected with the rack, and the other end is connected with the traction seat through the transmission wheel. Since the matching part is constrained by the steel rail and only moves in the vertical direction, the lifting frame will not bear too much transverse force, so the lifting frame can not be additionally transversely constrained. The person skilled in the art can also set a constraint matched with the lifting rail or other constraints for the lifting frame to further improve the stability.

[0032] Further, the driving mode two is as follows:

[0033] The second mounting seat is arranged outside the outward extension of the intermediate connecting member, and the winch is arranged on the second mounting seat. The winch is a manual winch or an electric winch. The winch is a self-locking winch to prevent falling;

[0034] The gantry is arranged at the top of the lifting guide rail, at least one transmission wheel is arranged in the middle of the gantry, one end of the flexible transmission member is wound around the roller shaft of the winch, and the other end is connected to the traction seat in a detachable hook connection manner.

[0035] Further, the device combines two driving modes, the adjustment of the hydraulic cylinder or air cylinder adopts the "moving pulley" mode to save labor, but if the air cylinder is adjusted in the foot pedal or pressing mode, it has a certain adjustment interval, and the continuous adjustment of the winch can more accurately and quickly adjust the clamping rod to the placement position or the taking position.

[0036] Further, the fixed wheel seat is arranged at the end of the support rod in the direction thereof, which can effectively reduce the height of the support rod and better adapt to the low placement rack of the base;

[0037] The front end of the rack body extends forward, and the extension part is arranged with a universal wheel seat in the vertical direction as the shaft;

[0038] The fixed wheel seat and the universal wheel seat are both arranged with traveling wheels, which can realize the walking and turning of the device.

[0039] The beneficial effects of the present application are: through the optimization of the design of the clamping member and the connecting plate, the rapid clamping and placing of the steel rail can be realized, the operation is simple, one person can complete the work, and the work efficiency is greatly improved.

[0040] It can be applied to high-density storage environment, and only a small space is needed in the transverse direction to complete the operation.

[0041] The clamping structure and the guide device connected in a door type can effectively avoid damage to the surface of the rail head during clamping, and improve the safety and stability of the overall operation.

[0042] By combining the driving modes of hydraulic cylinders, air cylinders or winches, the labor burden is reduced, and the fatigue impact on workers during long-term operation is reduced.

[0043] The overall structure of the device is compact, easy to use in different places and environments, and has walking and turning functions.

[0044] The modular design is adopted, the adapter and the transmission device are easy to disassemble and replace, and the maintenance cost of the device is reduced.

[0045] By combining the adjustment advantages of hydraulic cylinders or air cylinders and the continuous operation of winches, more accurate and rapid adjustment of the steel rail section can be realized.

[0046] In summary, the technical scheme has significant improvements in adaptability, safety and operation convenience, and can be widely applied to steel rail welding and handling work in railway maintenance sections, improving work efficiency and reducing safety risks.

DETAILED DESCRIPTION

[0057] Embodiment one

[0058] As shown in Figures 1-5 , an adapter for clamping a rail section, comprising a clamping part composed of two parallel flat clamping rods 1 and an adapter part perpendicular to the front ends of the clamping rods 1, the cross-sectional area of the clamping rod 1 is longer in the longitudinal direction than in the transverse direction, having higher vertical support force, the upper part of the clamping rod 1 is provided with a door-shaped connecting plate 2 connecting the two clamping rods 1.

[0059] The clamping mode of the adapter is that two straight clamping pieces pass through the rail waist on both sides, and the rail section is carried by lifting the adapter. The main support and limiting are performed by the clamping rod 1. If the connecting plate 2 is set too low, it is easy to act on the rail head and cause friction or scratch on the surface of the rail head. Therefore, the connecting plate 2 needs to be set higher than the surface of the rail head. The connecting plate 2 is used to relatively fix the positions of the two clamping pieces. Therefore, the connecting plate 2 needs to be set close to the end. The front end of the clamping piece is fixedly connected with the adapter part.

[0060] The connecting plate 2 can be segmented and set in multiple parts, or can be lengthened to reduce the number. A small number of short connecting plates 2 are more easily observed clamping conditions. Therefore, in the embodiment, one connecting plate 2 is set close to the end.

[0061] The front end of the clamping rod 1 is connected with the support plate 3 of the adapter part, and a reinforcing rib 4 is arranged at the connection position.

[0062] The top of the support plate 3 is provided with a first traction seat 5. The two sides of the first traction seat 5 are symmetrically provided with a second traction seat 6 and a third traction seat 7. The second traction seat 6 and the third traction seat 7 extend forward.

[0063] The support plate 3 is symmetrically provided with four connecting seats 8 extending forward on both sides. The two connecting seats 8 are located on the same horizontal plane. The connecting seat 8 is connected with a guide wheel 9.

[0064] Embodiment two:

[0065] Figures 6-11 As shown, a carrying device includes the adapter and a carrying device.

[0066] The carrying device includes a rack. The rack includes two support rods 10 parallel to the clamping piece. The bottom of the rail storage rack has a support leg. The two support rods 10 are arranged to better bypass the support leg to facilitate operation. After clamping the rail, the whole center of mass is offset to the rear end of the device. Therefore, the support rod 10 needs to be extended to the end of the clamping rod 1. The extension length is greater than the length of the clamping rod 1. The end of the support rod 10 is extended in the direction to set a fixed wheel seat 11. In this way, the height of the support rod 10 can be effectively reduced, and the carrying device is more suitable for the placement of the lower base 13.

[0067] The front end of the rack body extends forward. The extension part is provided with a universal wheel seat 12 in the vertical direction as the shaft. The fixed wheel seat 11 and the universal wheel seat 12 are both provided with traveling wheels. The traveling wheels can realize the walking and turning needs of the device.

[0068] The front end of the support rod 10 is connected through a support piece. The upper surface of the support piece is a base 13. Two vertical lifting guide rails 14 are arranged side by side on both sides of the base 13. The guide wheel 9 is located inside the lifting guide rail 14 and can roll in the vertical direction.

[0069] The middle part or the part close to the middle part of the lifting guide rail 14 on both sides of the rack is provided with an intermediate connector 15 which extends outward. A handle 16 is arranged below the intermediate connector 15, and the handle 16 is arranged symmetrically left and right to facilitate the operation of the staff.

[0070] Driving mode one:

[0071] The middle part of the base 13 is provided with a first mounting seat 17, and the first mounting seat 17 is used to arrange the cylinder body end 18 of the cylinder, and the lifting direction of the cylinder is consistent with the direction of the lifting guide rail 14;

[0072] The top end of the piston end 19 is provided with a lifting frame 20, and the lifting frame 20 is provided with a transmission wheel, that is, a relatively labor-saving dynamic pulley 31 mechanism. In order to improve the balance, the lifting frame 20 can be arranged in a symmetrical manner about the center of the cylinder body, and two sprockets 21 are arranged symmetrically at both ends of the lifting frame 20. One end of a transmission chain 22 is connected to the rack, and the other end passes through the transmission wheel and is connected to the second traction seat 6 and the third traction seat 7. Since the adapter part itself is constrained by the steel rail and only moves in the vertical direction, the lifting frame 20 will not bear excessive lateral force, so the lifting frame 20 can not be additionally constrained in the lateral direction. Those skilled in the art can also set a constraint matching the lifting guide rail 14 or other constraints for the lifting frame 20 to further improve stability.

[0073] Reference Figure 9 The side of the cylinder body is provided with a pump body piston 23 for filling gas into the cylinder. The pump body piston 23 is operated by any one of manual pressing and foot treading lever 25. Specifically, the side close to the bottom of the cylinder body end 18 is provided with a hinged seat 24, the end of the treading lever 25 is hinged to the hinged seat 24, and the position close to the end below is hinged to the pump body piston 23. The hinged part of the pump body piston 23 can be expanded hole connection, or the lower end of the pump body piston 23 is also hinged to the first connecting seat 8. In this way, mechanical interference can be avoided during pressing the pump body piston 23.

[0074] Manual pressing is realized by a pressing rod, which includes a lower rod body 26 and an upper hand holding part 27. The lower end of the rod body 26 is connected with a hinged shell 28, which can be nested on the outside of the end of the treading lever 25. The top surface of the end of the treading lever 25 is in contact with one edge or surface of the hinged shell 28. When the pressing rod is pressed, the treading lever 25 can be pressed to press down the pump body piston 23. When the treading lever 25 is used alone, the position of the pressing rod does not change. Here, the pressing rod and the cylinder body end 18 are connected by a spring, which is omitted in the drawing. When the spring is in the initial position, the pressing rod is vertical.

[0075] When descending, open the pressure relief valve on the cylinder.

[0076] Driving mode two:

[0077] The intermediate connecting piece 15 extends outwardly and is provided with a second mounting seat, and a winch is arranged on the second mounting seat. The winch is a hand-operated self-locking winch 29, which can prevent falling. A person skilled in the art can also install an emergency anti-falling device in the guide rail to further improve the safety.

[0078] A gantry 30 is arranged at the top of the lifting guide rail 14, two pulleys 31 are arranged in the middle of the gantry 30, and the pulleys 31 are arranged in front and back, respectively above the winch and above the support plate 3. One end of a steel wire rope 32 is wound around the roller shaft of the winch, and the other end is connected to the traction seat in a fixed connection or detachable hook connection manner through a transmission wheel. When the hook is used, the first traction seat 5 is correspondingly provided with a lug.

[0079] The device combines two driving modes. The adjustment of the hydraulic cylinder or the air cylinder adopts the "moving pulley 31" mode, which is more labor-saving. However, if the air cylinder is adjusted by the foot pedal or pressing mode, it has a certain adjustment interval. The continuous adjustment of the winch can more accurately and quickly adjust the clamping rod 1 to the placement position or the taking position. In order to avoid the influence of the winch self-locking on the god, the connection between the steel wire rope 32 and the support plate 3 is preferably connected by a hook. During the lifting by the air cylinder, the hook can be removed.
