Description

Technical Field

[0001] The invention relates to an equidistant laying vehicle for stacked sleepers, belonging to the technical field of sleeper laying. Background Art

[0002] The railway transportation system includes many elements, such as vehicles, tracks, various dispatching controls, communication signals and monitoring and early warning equipment, as well as related management systems and operators, and they complement each other. Without a suitable system, the train will not be able to run smoothly. The first is the geographical environment along the railway, including geology and topography. The second is the purpose of the system: passenger or freight. If it is passenger transportation, it is also necessary to consider whether the passengers are commuters or medium- and long-distance travelers. When the needs are figured out, it is necessary to decide the type of railway to be built: for example, light rail or heavy rail. There are also monorails, rubber wheel track systems and maglev railways, because the trains on these lines are also guided by tracks. Many large cities now have urban rail transit systems or tram systems. After that, the track gauge must be selected. If it is electricity, an electrified system is required. In this way, there are different ways to power the train. The most common is overhead cable and track power supply. Finally, the number of tracks must be determined based on the traffic flow. If the traffic is small, only one track can be built, but there must be a shelter for more than one train to use this railway. For roads with heavy traffic, double or even multiple tracks can be laid. Some busy sections even have eight parallel tracks, with four tracks in each direction.

[0003] Laying of tracks is an important step in the construction of railways. The existing laying methods include manual laying of sleepers, sleeper laying engineering vehicles, and large-scale engineering vehicles for integrated laying of sleepers and rails. Among them, the sleeper laying engineering vehicle is larger in size and suitable for relatively flat and wide terrain, while the large-scale engineering vehicle for integrated laying of sleepers and rails is very large in size and can only be used in flat and wide terrain. China's terrain is complex and diverse. Most of China's railway trunk lines pass through mountains and ridges. When laying tracks in some mountainous terrains, due to the complex and narrow terrain environment, the above-mentioned sleeper laying vehicles and large-scale engineering vehicles for integrated laying of sleepers and rails cannot be used in this type of terrain environment, and can only be laid manually. Therefore, a stacked sleeper equidistant laying vehicle that can be used at narrow mountain construction sites is studied for sleeper laying in complex and narrow mountains. Summary of the invention

[0004] The purpose of the present invention is to provide a vehicle for equidistantly laying sleepers in stacked state. The device can meet the needs of complex environments and narrow mountains, and can replace sleeper laying engineering vehicles and large engineering vehicles for integrated sleeper and rail laying in the above environment, thereby reducing the workload of workers. At the same time, the device can convert the stacked sleepers into a single layer, and then lay the sleepers equidistantly on the railway roadbed.

[0005] A vehicle for equidistantly laying sleepers in a stacked state comprises a vehicle plate, a sliding plate, a belt conveyor and a blocking mechanism; the characteristics are as follows: the tail end of the vehicle plate is a sliding plate inclined downward, the bottom of the vehicle plate is respectively provided with a front wheel and a rear wheel, the front end of the vehicle plate is provided with an opening, and a belt conveyor is installed in the opening; considering that the sleepers are heavy and the belt conveyor cannot bear the weight, the upper surface of the belt conveyor is located lower than the upper surface of the vehicle plate, and paddle plates are fixed at fixed intervals on the conveyor belt of the belt conveyor, and the spacing between every two paddle plates is the same as the bottom width of the sleepers, so that the paddle plates can fix the sleepers; if the spacing between the paddle plates is too large, the sleepers will slide left and right on the vehicle plate, and a fence is fixed on the edge of the vehicle plate, the tail end of the fence is inclined backward and a discharge port is provided at the bottom, a third through hole is provided on the tail end of the fence, and the third through hole is provided on the tail end of the fence. A hydraulic cylinder is installed at the through hole, and the telescopic end of the hydraulic cylinder passes through the third through hole. A push plate is provided at the telescopic end of the hydraulic cylinder, and the bottom of the push plate extends above the discharge port. When the belt conveyor transports the sleepers to the discharge port of the slide plate, the last vertical row of sleepers will lean on the inclined part of the enclosure, and the hydraulic cylinder drives the push plate to push the second and above sleepers, and lay the second layer of sleepers on the slide plate. The hydraulic cylinder drives the push plate to reset, and repeats this process. The sleepers in this row will be laid on the slide plate one by one, and a blocking mechanism is installed at the tail of the slide plate. When the blocking mechanism controls the rearmost sleeper on the slide plate to slide down, it will block other sleepers on the slide plate from sliding, so as to prevent multiple sleepers from sliding down onto the railway roadbed at one time, or the sleepers from sliding under the blocking mechanism, jamming the blocking mechanism and preventing it from resetting.

[0006] When setting up the above-mentioned car plate, taking into account that the surface of the sleeper is relatively rough, the friction force is large when the car plate and the slide plate slide, and sliding is difficult, so rollers are provided on the left and right sides of the car plate and the slide plate respectively. The rollers can help the sleeper slide, avoid friction between the sleeper and the car plate slide plate, and avoid damage to the sleeper, car plate and slide plate.

[0007] When the above-mentioned blocking mechanism is specifically set up, the blocking mechanism includes a blocking frame, a base, a tilting rod, a first clip, a second clip, and an electric telescopic rod; the blocking frame is installed at the tail of the sliding plate, and the blocking frame can also play a role of limiting to prevent the sleeper from running off the sliding plate. A base is fixed at the middle position of the top of the blocking frame, and second through holes are respectively provided on the front and rear sides of the base. A tilting rod is connected to the base, and the front and rear ends of the tilting rod are respectively hingedly fixed with the second clip and the first clip by hinges, and the first clip and the second clip pass through the second through hole respectively. A fixed frame is fixed on the top of the blocking frame, and an electric telescopic rod is installed on the fixed frame. The electric telescopic rod has two functions of extension and contraction when executing a command The electric telescopic rod acts on the second catch, and the distance between the second catch and the first catch is just the width of a sleeper. The first catch and the second catch are respectively caught on both sides of the penultimate sleeper. When the electric telescopic rod extends, the second catch moves downward, the first catch moves upward, and the penultimate sleeper will fall onto the railway roadbed, and the second catch will catch the penultimate and above sleepers to prevent them from moving. Then the electric telescopic rod contracts upward, the first catch moves downward, and the second catch moves upward, and the sleepers on the slide plate slide down to be supplemented with a new penultimate sleeper, which can effectively prevent multiple sleepers from sliding off the slide plate.

[0008] When setting up the above-mentioned sleepers, considering that the sleepers need to be laid at equal intervals, the electric telescopic rod needs to work repeatedly periodically to allow the sleepers to fall from the slide plate to the railway roadbed at equal intervals. Therefore, the sleepers need to be laid at equal intervals. The electric telescopic rod is provided with a trigger device. Whenever the distance traveled by the rear wheel is equal to the laying spacing of the sleepers, the trigger device triggers the electric telescopic rod to work, and the trigger button will continue to be triggered during the movement of the rear wheel. The trigger device includes a first pulley, a second pulley, a belt, a touch rod, a mounting frame, and a button. The first pulley is installed on the rear wheel axle, and the second pulley is fixed to the bottom of the slide plate. The belt is sleeved on the first pulley and the second pulley, and a touch rod is fixed on the belt. The mounting frame is fixed behind the second pulley, and a button is installed on the mounting frame. The button is a switch that triggers the operation of the electric telescopic rod. Whenever the belt rotates one circle, the touch rod will trigger the button once. Even if the vehicle's driving speed changes, the circumference of the belt is determined, and the distance traveled by the rear wheel drive belt trigger button switch must remain unchanged.

[0009] When setting up the above-mentioned mounting frame, it is taken into consideration that when the present invention is not performing the work of laying sleepers, the belt is still in a transmission state while the vehicle is moving, and the feeler rod on the belt will continuously touch the button, resulting in ineffective loss of the button. Therefore, a slideway is provided on the mounting frame, and a screw rod is provided at the bottom of the button. The screw rod is inserted into the slideway, and the button can slide back and forth on the mounting frame to adjust its position. A nut is installed on the screw rod, and the position of the button is locked by the nut. When the work of laying sleepers is not performed, the position of the button is moved backward to be out of the touchable position of the feeler rod.

[0010] When setting up the above-mentioned mounting frame, it is taken into consideration that when the present invention is not performing the work of laying sleepers, the belt is still in a transmission state while the vehicle is moving, and the touch rod on the belt will continuously touch the button, resulting in ineffective loss of the button. Therefore, an electric push rod is fixed on the mounting frame, and the button is fixed at the telescopic end of the electric push rod. The electric push rod controls the front and rear positions of the button. When the work of laying sleepers is not performed, the position of the button is moved backward to be out of the touchable position of the touch rod.

[0011] When setting up the above-mentioned enclosure, considering that every time a vertical row of sleepers falls on the inclined part of the enclosure, there will be a huge impact force, an external frame is provided on the inclined part of the rear end of the enclosure, and a first through hole is opened on the external frame and the enclosure, a fixing column is installed in the first through hole, a buffer plate is installed at the front end of the fixing column, a chuck is installed in the middle of the fixing column, and a spring is installed behind the chuck. When a vertical row of sleepers falls, they will fall on the buffer plate and part of the impact force will be offset by the spring.

[0012] The beneficial effect of the present invention is to provide a vehicle for equidistantly laying stacked sleepers. The device does not require traction from a non-powered vehicle and meets the needs of complex environments and narrow mountainous areas. It can replace sleeper laying engineering vehicles and large engineering vehicles for integrated sleeper and rail laying in the above-mentioned environments, thereby reducing the workload of workers. At the same time, the device can convert the stacked sleepers into a single layer and then lay the sleepers equidistantly on the railway bed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings. The following description is only used to illustrate the technical solution of the present invention rather than to limit it.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention; in addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features; thus, the features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0027] As shown in the figure, a equidistant laying vehicle for stacked sleepers comprises a vehicle plate 1, a sliding plate 2, a belt conveyor 8 and a blocking mechanism; the characteristics are as follows: the tail of the vehicle plate 1 is a sliding plate 2 inclined downward, the bottom of the vehicle plate 1 is respectively equipped with a front wheel 3 and a rear wheel 4, both of which are parallel twin tires, so that the vehicle plate 1 is more stable when traveling on the railway roadbed; the front end of the vehicle plate 1 is provided with an opening 6, a belt conveyor 8 is installed in the opening 6, a notch 7 is provided on the sliding plate 2 at the tail end of the opening 6, and the tail end of the belt conveyor 8 is "embedded" in the sliding plate 2, It is easier to transport the sleepers on the car plate 1 to the sliding plate 2. Considering that the weight of the sleepers is too heavy and the belt conveyor 8 cannot bear the weight, the upper surface of the belt conveyor 8 is lower than the upper surface of the car plate 1. The conveyor belt of the belt conveyor 8 is fixed with paddles 9 at fixed intervals. The distance between every two paddles 9 is the same as the bottom width of the sleepers. In this way, the paddles 9 can fix the sleepers. If the distance between the paddles 9 is too large, the sleepers will slide left and right on the car plate 1. The edge of the car plate 1 is fixed with a fence 10, and the fence 10 is open around the head on three sides. The U-shape is convenient for adding sleepers on the car plate 1. The tail of the enclosure 10 is tilted backward and a discharge port 11 is provided at the bottom. A third through hole 36 is provided on the tail of the enclosure 10. A hydraulic cylinder 37 is installed at the third through hole 36. The telescopic end of the hydraulic cylinder 37 passes through the third through hole 36. A push plate 38 is provided at the telescopic end of the hydraulic cylinder 37. The bottom of the push plate 38 extends above the discharge port 11. When the belt conveyor 8 transports the sleepers to the discharge port 11 of the sliding plate 2, the tailmost vertical row of sleepers will lean against the inclined part of the enclosure 10. The hydraulic cylinder 37 is installed at the third through hole 36. The telescopic end of the hydraulic cylinder 37 passes through the third through hole 36. A push plate 38 is provided at the telescopic end of the hydraulic cylinder 37. The bottom of the push plate 38 extends to the top of the discharge port 11. When the belt conveyor 8 transports the sleepers to the discharge port 11 of the sliding plate 2, the tailmost vertical row of sleepers will lean against the inclined part of the enclosure 10. The cylinder 37 drives the push plate 38 to push the second layer and above sleepers, and lay the sleepers of the second layer flat on the sliding plate 2. The hydraulic cylinder 37 drives the push plate 38 to reset. This process is repeated. The row of sleepers will be laid flat on the sliding plate 2 one by one. A blocking mechanism is installed at the tail of the sliding plate 2. When the blocking mechanism controls the rearmost sleeper on the sliding plate 2 to slide down, it will block the sliding of other sleepers on the sliding plate 2 to prevent multiple sleepers from sliding down onto the railway roadbed at one time, or the sleepers from sliding under the blocking mechanism, jamming the blocking mechanism and preventing it from resetting.

[0028] When the above-mentioned car plate 1 is specifically set up, considering that the surface of the sleeper is relatively rough, the friction force is large when sliding on the car plate 1 and the sliding plate 2, and sliding is difficult, so rollers 5 are respectively provided on the left and right sides of the car plate 1 and the sliding plate 2. The rollers 5 can help the sleeper to slide, avoid friction between the sleeper and the car plate 1 and the sliding plate 2, and avoid damage to the sleeper, car plate 1, and the sliding plate 2.

[0029] When the above-mentioned blocking mechanism is specifically set, the blocking mechanism includes a blocking frame 18, a base 19, a tilting rod 21, a first clip 23, a second clip 24, and an electric telescopic rod 26; the blocking frame 18 is installed at the tail end of the sliding plate 2, and the blocking frame 18 can also play a role of limiting to prevent the sleeper from deviating on the sliding plate 2. A base 19 is fixed to the middle position of the top of the blocking frame 18, and a second through hole 20 is respectively provided on the front and rear sides of the base 19. A tilting rod 21 is connected to the base 19, and the front and rear ends of the tilting rod 21 are respectively hingedly fixed with the second clip 24 and the first clip 23 by hinges 22. Considering that the sleeper is larger at the top and smaller at the bottom, a conical gap will be formed at the top of two adjacent sleepers, so the bottoms of the first clip 23 and the second clip 24 are both conical, which can just be stuck in this gap. The first clip 23 and the second clip 24 pass through the second through hole 20 respectively, and a fixing frame 25 and an upper surface of the fixing frame 25 are fixed to the top of the blocking frame 18. An electric telescopic rod 26 is installed. The electric telescopic rod 26 has two actions of extension and contraction when executing a command. The electric telescopic rod 26 acts on the second catch 24 (the effect achieved on the first catch 23 when the electric telescopic rod 26 acts is the same). The distance between the second catch 24 and the first catch 23 is just the width of a sleeper. The first catch 23 and the second catch 24 are respectively stuck on both sides of the penultimate sleeper. When the electric telescopic rod 26 extends, the second catch 24 moves downward, the first catch 23 moves upward, and the penultimate sleeper will fall onto the railway roadbed, and the second catch 24 will block the penultimate and above sleepers to prevent them from moving. Then the electric telescopic rod 26 contracts upward, the first catch 23 moves downward, and the second catch 24 moves upward, and the sleepers on the slide plate 2 slide downward to be supplemented with a new penultimate sleeper, which can effectively prevent multiple sleepers from sliding off the slide plate 2.

[0030] When the above-mentioned sleepers are specifically set up, considering that the sleepers need to be laid at equal intervals, the electric telescopic rod 26 needs to work repeatedly periodically to allow the sleepers to fall from the sliding plate 2 to the railway roadbed at equal intervals. Therefore, the sleepers need to be laid at equal intervals. The electric telescopic rod 26 is provided with a trigger device. Whenever the distance traveled by the rear wheel 4 is equal to the laying spacing of the sleepers, the trigger device triggers the electric telescopic rod 26 to work. During the movement of the rear wheel 4, the trigger button 32 will continue. The trigger device includes a first pulley 27, a second pulley 28, a belt 29, a touch rod 30, a mounting frame 31, and a button 32. The first pulley 27 is installed on the rear wheel 4 On the shaft, the second pulley 28 is fixed at the bottom of the sliding plate 2, the belt 29 is sleeved on the first pulley 27 and the second pulley 28, and a touch rod 30 is fixed on the belt 29, the end of the touch rod 30 is a rubber round head, and the mounting frame 31 is fixed behind the second pulley 28. A button 32 is installed on the mounting frame 31. The button 32 is a switch that triggers the operation of the electric telescopic rod 26. Every time the belt 29 rotates one circle, the touch rod 30 will trigger the button 32 once. Even if the vehicle's driving speed changes, the circumference of the belt 29 is determined, and the distance traveled by the rear wheel 4 drive belt 29 to trigger the button 32 switch must remain unchanged.

[0031] When the above-mentioned mounting frame 31 is specifically set up, it is taken into consideration that when the present invention is not performing the work of laying sleepers, the belt 29 is still in a transmission state while the vehicle is moving, and the touch rod 30 on the belt 29 will continuously touch the button 32, resulting in ineffective loss of the button 32. Therefore, a slideway 33 is provided on the mounting frame 31, and a screw rod 34 is provided at the bottom of the button 32. The screw rod 34 is inserted into the slideway 33, and the button 32 can slide back and forth on the mounting frame to adjust its position. A nut 35 is installed on the screw rod 34, and the position of the button 32 is locked by the nut 35. When the work of laying sleepers is not performed, the position of the button 32 is moved backward to be out of the touchable position of the touch rod 30.

[0032] When the above-mentioned mounting frame 31 is specifically set up, it is taken into consideration that when the present invention is not performing the work of laying sleepers, the belt 29 is still in a transmission state while the vehicle is moving, and the touch rod 30 on the belt 29 will continuously touch the button 32, resulting in ineffective loss of the button 32. Therefore, an electric push rod is fixed on the mounting frame 31, and the button 32 is fixed at the telescopic end of the electric push rod. The electric push rod controls the front and rear positions of the button 32. When the work of laying sleepers is not performed, the position of the button 32 is moved backward to be out of the touchable position of the touch rod 30.

[0033] When the above-mentioned enclosure 10 is specifically set up, considering that every time a vertical row of sleepers falls on the inclined part of the enclosure 10, there will be a huge impact force, so the inclined part of the tail of the enclosure 10 is provided with an external frame 12, and a first through hole 13 is opened on the external frame 12 and the enclosure 10, and a fixing column 15 is installed in the first through hole 13, and a buffer plate 14 is installed at the front end of the fixing column 15, and a chuck 16 is installed in the middle of the fixing column 15, and a spring 17 is installed behind the chuck 16. When a vertical row of sleepers falls, they will fall on the buffer plate 14, and part of the impact force will be offset by the spring 17.

[0034] Although the present invention has been described in detail with reference to the aforementioned examples, it is still possible for those skilled in the art to make and modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
