Description

Technical Field

[0001] This invention belongs to the technical field of track laying, and more specifically, relates to a ballast track bed sleeper device. Background Technology

[0002] Railway lines are mainly divided into two types: ballasted track and ballastless track. Ballasted track requires the laying of sleepers, but before laying the sleepers, the ballast must be spread and leveled, then the sleeper spacing is measured with a steel ruler, and quicklime is sprinkled to mark the position of the rails on the track. Typically, railways have long distances and many lines, and this sleeper laying method requires significant adjustments to the sleeper spacing and lateral positions, which is time-consuming, inefficient, labor-intensive, and consumes a large amount of human resources. Moreover, due to the low accuracy of the sleeper spacing and lateral positions, multiple manual corrections are still required later. Currently, large sleeper laying equipment is typically used to lay sleepers along the track line.

[0003] Existing pillow-laying equipment typically lays pillows at a fixed distance, and the distance cannot be adjusted according to the actual construction conditions. Summary of the Invention

[0004] The purpose of this invention is to provide a ballast track bed pillow device, which aims to solve the problem that existing pillow devices cannot flexibly adjust the pillow spacing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a ballast track bed pillow device, comprising:

[0006] The system includes a traveling mechanism, a spacing adjustment mechanism mounted on the traveling mechanism, a clamping mechanism mounted on the spacing adjustment mechanism, and a driving component; the clamping mechanism is used to clamp the sleeper.

[0007] The spacing adjustment mechanism includes: four telescopic rods distributed at the four corners of a rectangle and four horizontal rods horizontally arranged on the top of the telescopic rods; the horizontal rods are distributed along the four sides of the rectangle, and the two ends of the horizontal rods are respectively hinged to the top of the adjacent telescopic rods; one end of the driving member is hinged to the walking mechanism, and the other end is hinged to the telescopic rod; the clamping mechanism is arranged on the horizontal rod.

[0008] In one possible implementation, the telescopic rod includes:

[0009] A base is hinged to the walking mechanism; the base has an air chamber inside.

[0010] A piston rod is slidably connected in the air chamber; the horizontal rod is connected to the top of the piston rod; and

[0011] A cover is fixedly connected to the base; the cover is used to seal the air chamber; an air inlet and an exhaust channel are provided on the side wall of the base; the air inlet and the exhaust channel are located on the side of the piston rod away from the cover, and a pressure relief valve is provided on the exhaust channel.

[0012] In one possible implementation, the piston rod includes:

[0013] A piston portion is slidably disposed inside the air chamber; the piston portion is interference-fitted with the inner wall of the air chamber; and

[0014] A sliding rod is fixedly connected at one end to the piston part and at the other end to the horizontal rod; a through hole is provided on the cover, and the sliding rod is slidably inserted into the through hole; the air intake passage and the exhaust passage are located on the side of the piston part away from the cover.

[0015] In one possible implementation, a positioning rod is threaded onto the cover, one end of which is located inside the air chamber, and the high-pressure gas in the air chamber pushes the piston against the positioning rod.

[0016] In one possible implementation, a pressure sensor is further included for detecting the pressure between the piston portion and the positioning rod. The pressure sensor is disposed at the end of the positioning rod and located between the positioning rod and the piston portion.

[0017] In one possible implementation, a control module is also included that is communicatively connected to both the pressure sensor and the pressure relief valve. The pressure sensor detects the pressure between the piston and the positioning rod in real time and sends the real-time pressure information to the control module. The control module controls the pressure relief valve to operate based on the real-time pressure information.

[0018] In one possible implementation, the control module includes a controller that is communicatively connected to both the pressure sensor and the pressure relief valve. After receiving the real-time pressure information, the controller compares the real-time pressure information with a pressure threshold. If the real-time pressure information is not less than the pressure threshold, the controller controls the pressure relief valve to open to reduce or maintain the pressure in the air chamber. If the real-time pressure information is less than the pressure threshold, the controller controls the pressure relief valve to close to increase the pressure in the air chamber.

[0019] In one possible implementation, if the real-time pressure information is not less than the pressure threshold, then the difference between the real-time pressure information and the pressure threshold is calculated; the controller controls the opening degree of the pressure relief valve based on the difference.

[0020] In one possible implementation, the spacing adjustment mechanism has multiple layers, and adjacent spacing adjustment mechanisms are fixedly connected.

[0021] In one possible implementation, the adjacent telescopic rods are fixedly connected.

[0022] The beneficial effects of the ballast track sleeper laying device provided by this invention are as follows: Compared with the prior art, in the sleeper laying process, this invention first uses the clamping mechanism on the spacing adjustment mechanism to fix the sleepers, then adjusts the spacing between adjacent sleepers by adjusting the length of the telescopic rod, and then drives the telescopic rod to gradually turn horizontally by the driving component. Finally, the clamping mechanism places the sleepers in the designated positions. During the sleeper laying process, workers can adjust the sleeper spacing by adjusting the length of the telescopic rod. Attached Figure Description

[0028] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0029] Reference Figure 1 and Figure 2 The ballast track bed pillow device provided by the present invention will now be described.

[0030] Reference Figure 1The ballast bed sleeper device includes a traveling mechanism 1, a spacing adjustment mechanism 2 mounted on the traveling mechanism 1, a clamping mechanism 3 mounted on the spacing adjustment mechanism 2, and a driving component 4; the clamping mechanism 3 is used to clamp the sleepers.

[0031] The spacing adjustment mechanism 2 includes: four telescopic rods 21 distributed at the four corners of a rectangle and four horizontal rods 22 horizontally positioned on top of the telescopic rods 21; the horizontal rods 22 are distributed along the four sides of the rectangle, and both ends of the horizontal rods 22 are hinged to the top of the adjacent telescopic rods 21; one end of the driving member 4 is hinged to the walking mechanism 1, and the other end is hinged to the telescopic rod 21. A clamping mechanism 3 is mounted on the horizontal rods 22. The horizontal rods 22 are connected to the top of the piston rod 212.

[0032] The traveling mechanism 1 is a movable trolley, which is an automatically driven trolley. This trolley can be driven by an electric motor or powered by an internal combustion engine. The spacing adjustment mechanism 2 and the drive unit 4 are mounted on the trolley. The clamping mechanism 3 is used to clamp and fix the sleepers. During sleeper placement, the drive unit 4 first drives each telescopic rod 21 to stabilize it in a vertical position. Then, the sleepers are placed in the clamping mechanism 3, and the sleeper spacing between adjacent sleepers is adjusted by adjusting the telescopic rods 21. After adjusting the sleeper spacing, the drive unit 4 drives the telescopic rods 21 to gradually level them, and then the clamping mechanism 3 releases the sleepers, placing them in the designated positions.

[0033] The beneficial effects of the ballast track sleeper laying device provided by this invention are as follows: Compared with the prior art, in the sleeper laying process, the sleepers are first fixed by the clamping mechanism 3 on the spacing adjustment mechanism 2, then the spacing between adjacent sleepers is adjusted by adjusting the length of the telescopic rod 21, and then the telescopic rod 21 is driven by the driving component 4 to gradually turn horizontally, and finally the clamping mechanism 3 places the sleepers in the designated positions. During the sleeper laying process, workers can adjust the sleeper spacing by adjusting the length of the telescopic rod 21.

[0034] Reference Figure 2 In one possible implementation, the telescopic rod 21 includes: a base 211, a piston rod 212, and a cover 213.

[0035] The base 211 is hinged to the traveling mechanism 1; an air chamber is provided inside the base 211; the piston rod 212 is slidably connected in the air chamber; the cover 213 is fixedly connected to the base 211; the horizontal rod 22 is connected to the top of the piston rod 212; the cover 213 is used to seal the air chamber; an air inlet and an exhaust channel are provided on the side wall of the base 211; the air inlet and exhaust channel are located on the side of the piston rod 212 away from the cover 213, and a pressure relief valve is provided on the exhaust channel. The air inlet is connected to an air source, and the air source enters the air chamber through the air inlet, increasing the pressure inside the air chamber. When the pressure in the air chamber reaches a specified pressure, the pressure relief valve opens, and pressure is released to maintain a stable pressure in the air chamber. Under the action of high pressure in the air chamber, the piston rod 212 is pushed towards the cover 213.

[0036] In one possible implementation, the piston rod 212 includes a piston portion 2121 and a slide rod 2122.

[0037] The piston part 2121 is slidably disposed inside the air chamber; the piston part 2121 is interference-fitted with the inner wall of the air chamber; one end of the slide rod 2122 is fixedly connected to the piston part 2121, and the other end is connected to the horizontal rod 22; the cover 213 is provided with a through hole, and the slide rod 2122 is slidably inserted into the through hole; the air intake and exhaust passages are located on the side of the piston part 2121 away from the cover 213. The diameter of the piston part 2121 is smaller than the inner diameter of the air chamber, and the side of the piston part 2121 is provided with an annular mounting groove, in which an annular sealing ring is installed. The elastic deformation of the sealing ring is used to seal the gap between the piston part 2121 and the inner wall of the air chamber, thereby achieving an interference fit between the piston part 2121 and the inner wall of the air chamber. The cover 213, the piston part 2121, and the slide rod 2122 are all coaxially arranged. The cover 213 is connected to the base 211 by bolts. A through hole is provided at the axial position of the cover 213. One end of the slide rod 2122 is fixedly connected to the piston part 2121, and the other end is transmitted out from the through hole, exposed outside the air chamber, and connected to the horizontal rod 22.

[0038] In one possible implementation, a positioning rod 2123 is threaded onto the cover 213. One end of the positioning rod 2123 is located inside the air chamber, and the high-pressure gas in the air chamber pushes the piston part 2121 against the positioning rod 2123. When adjusting the length of the telescopic rod 21, the positioning rod 2123 is rotated. During the rotation of the positioning rod 2123, under the action of the thread, the positioning rod begins to move along the axial direction of the air chamber. When it is necessary to extend the length of the telescopic rod 21, the positioning rod 2123 is rotated to reduce the length of the positioning rod 2123 in the air chamber; when it is necessary to shorten the length of the telescopic rod 21, the positioning rod 2123 is rotated to increase the length of the positioning rod 2123 in the air chamber. Under the action of high pressure in the air chamber, the piston part 2121 abuts against the positioning rod 2123.

[0039] In one possible implementation, a pressure sensor 2124 is also included for detecting the pressure between the piston portion 2121 and the positioning rod 2123. The pressure sensor 2124 is disposed at the end of the positioning rod 2123 and located between the positioning rod 2123 and the piston portion 2121.

[0040] In one possible implementation, a control module is also included that is communicatively connected to both the pressure sensor 2124 and the pressure relief valve. The pressure sensor 2124 detects the pressure between the piston 2121 and the positioning rod 2123 in real time and sends the real-time pressure information to the control module. The control module controls the operation of the pressure relief valve based on the real-time pressure information.

[0041] In one possible implementation, the control module includes a controller that is communicatively connected to both the pressure sensor 2124 and the pressure relief valve. After receiving real-time pressure information, the controller compares the real-time pressure information with a pressure threshold. If the real-time pressure information is not less than the pressure threshold, the controller controls the pressure relief valve to open to reduce or maintain the pressure in the air chamber. If the real-time pressure information is less than the pressure threshold, the controller controls the pressure relief valve to close to increase the pressure in the air chamber.

[0042] Driven by the air source, the telescopic rod 21 stabilizes at the set length. Under high pressure in the air chamber, the piston 2121 abuts against the positioning rod 2123. At this time, the pressure sensor 2124 detects the pressure between the piston 2121 and the positioning rod 2123 in real time and transmits it to the controller as real-time pressure information. After receiving the real-time pressure information, the controller compares the real-time pressure information with the pressure threshold. If the real-time pressure information is less than the pressure threshold, it means that the piston 2121 has failed to make stable contact with the positioning rod 2123. At this time, the length of the telescopic rod 21 has not reached the set length, and the pressure in the air chamber needs to be increased further. Conversely, if the real-time pressure information is not less than the pressure threshold, it means that the piston 2121 is in stable contact with the positioning rod 2123. At this time, the length of the telescopic rod 21 has reached the set length, and the air chamber needs to be depressurized to avoid excessive pressure in the air chamber.

[0043] In one possible implementation, if the real-time pressure information is not less than the pressure threshold, the difference between the real-time pressure information and the pressure threshold is calculated; the controller controls the opening degree of the pressure relief valve based on the difference.

[0044] When the real-time pressure information is not less than the pressure threshold, the difference between the real-time pressure information and the pressure threshold is calculated. The controller compares this difference with a first difference threshold. If the difference is not greater than the first difference threshold, it means that the pressure in the air chamber has not exceeded the pressure threshold by much, and the controller controls the opening of the pressure relief valve to the first opening degree. If the difference is greater than the first difference threshold, it means that the pressure in the air chamber exceeds the pressure threshold by a large margin, and the controller controls the opening of the pressure relief valve to the second opening degree. It should be noted that the first difference threshold is less than the second difference threshold, and the first opening degree is less than the second opening degree.

[0045] In one possible implementation, the spacing adjustment mechanism 2 is provided in multiple layers, with adjacent spacing adjustment mechanisms 2 fixedly connected.

[0046] In one possible implementation, adjacent telescopic rods 21 are fixedly connected.

[0047] In a preferred embodiment, the clamping mechanism 3 can be a robotic arm for clamping and fixing sleepers, or it can consist of two cylinders positioned opposite each other. When clamping and fixing the sleeper, the drive unit 4 first drives the telescopic rod 21 to rotate to a vertical position. Then, the sleeper is placed between the two cylinders, and the cylinders clamp and fix the sleeper in place. Next, the positioning rod 2123 is rotated to adjust the length of the telescopic rod 21, thereby adjusting the distance between adjacent sleepers to the planned sleeper spacing. When the telescopic rod 21 reaches the set length, the drive unit 4 drives the telescopic rod 21 to rotate to a horizontal position. Then, the clamping assembly releases the sleeper, placing it in the designated position, completing the sleeper laying.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
