Description

Technical Field

[0001] The present invention discloses the technical field of concrete sleeper production, and specifically discloses an automatic drawing machine for pre-embedded rubber rods of sleepers and an efficient production system for sleepers. Background Art

[0002] In the production of sleepers, in order to meet the process requirements, a number of reserved holes need to be reserved on the sleepers. The reserved holes are formed by removing the rubber rods pre-embedded before production after production. Since the concrete has solidified, it is very difficult to remove the rubber rods. It requires multiple employees to loosen them with large pliers and then extract them by force, which is both laborious and time-consuming, resulting in low production efficiency of sleepers.

[0003] To solve the above problems, a Chinese invention patent with the publication number CN208118105U discloses a rubber rod extraction device and an extraction device. The extraction device includes a connecting head and a winch. One end of the connecting head is provided with a first traction member, and the other end is provided with a second traction member. The first traction member is connected to the extracted rubber rod, and the second traction member is connected to the winch. This extraction device uses a winch for extraction to solve the problem of low efficiency of manual extraction. Since the above extraction device can only extract one rubber rod at a time and cannot extract multiple rubber rods simultaneously, the efficiency is low. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic drawing machine for pre-embedded rubber rods of sleepers that can simultaneously draw out multiple rubber rods.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: an automatic drawing machine for pre-embedded rubber rods of sleepers, including a frame and a clamping device and a drawing device provided on the frame. The clamping device includes multiple groups of clamping components, a linkage beam, a fixed beam, and a clamping cylinder. Each group of clamping components includes two relatively arranged clamping arms. One end of the clamping arm is connected to the linkage beam, and the middle part is hinged to the fixed beam. The end of the clamping arm far from the linkage beam is fixedly connected with a clamping plate. Driven by the clamping cylinder, the linkage beam drives the clamping components to open and close to clamp the rubber rod.

[0006] Further, the linkage beam includes an upper linkage beam and a lower linkage beam that are arranged opposite to each other up and down. The upper and lower linkage beams are respectively connected to the corresponding clamping cylinders through connecting seats and are driven by the corresponding clamping cylinders to perform reciprocating linear motion.

[0007] Further, one clamping arm of each group of clamping components is connected to the upper linkage beam, and the other clamping arm is connected to the lower linkage beam.

[0008] Further, the fixed beam includes an upper fixed beam and a lower fixed beam. The upper and lower fixed beams are both fixed on the frame, and there is a gap between the upper and lower fixed beams for the clamping arms to pass through.

[0009] Further, anti-slip ridges are provided on the working surface of the clamping plate.

[0010] Further, the pulling device includes pulling cylinders arranged at both ends of the frame.

[0011] Further, moving wheels are provided at the bottom of the frame.

[0012] Further, the automatic pulling machine for sleeper embedded rubber rods further includes a moving platform, and the moving platform is arranged below the frame.

[0013] The present invention also provides an efficient sleeper production system, which includes a concrete sleeper production line and the automatic pulling machine for sleeper embedded rubber rods described above. A walking track is laid on one side of the concrete sleeper production line, and the automatic pulling machine for sleeper embedded rubber rods that can move along the walking track is provided on the walking track.

[0014] The automatic pulling machine for sleeper embedded rubber rods applying the technical solution of the present invention has the following advantages compared with the prior art: Multiple sets of clamping components are linked by two clamping cylinders to achieve opening and closing simultaneously, so as to clamp multiple rubber rods at the same time, and multiple rubber rods can be pulled out simultaneously, with high efficiency, easy operation, and convenient for popularization and implementation.

[0015] The efficient sleeper production system applying the technical solution of the present invention has the following advantages compared with the prior art: The automatic pulling machine for sleeper embedded rubber rods is arranged on one side of the concrete sleeper production line, and the automatic pulling machine for sleeper embedded rubber rods is moved according to the position of the sleeper that needs to pull out the embedded rubber rod. At the same time, the rubber rods in one steel mold or one sleeper are pulled out, and the embedded rubber rods in one sleeper are pulled out at the same time, with high efficiency and improved production efficiency of the sleeper.

Detailed implementation manners

[0024] Hereinafter, the implementation manners of the metal sheet rolling and bending forming device of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following implementation manners:

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present invention is usually placed, or the orientation or positional relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0026] In addition, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "installed", "connected" 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 directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0027] An automatic pulling machine for pre - embedded rubber rods of sleepers provided by the present invention, as Figure 1 shown, includes a frame 1, a clamping device 2 and a pulling device 3, and the clamping device 2 and the pulling device 3 are both arranged on the frame 1.

[0028] The clamping device 2 includes multiple groups of clamping assemblies 500, a linkage beam 200, a fixed beam 400, and a clamping cylinder 600. The number of clamping assemblies 500 is determined according to the number of adhesive rods 10 on each sleeper 11. In this embodiment, each sleeper 11 is provided with 5 reserved holes, so there are 5 adhesive rods 10, and thus the number of clamping assemblies 500 is 5 groups. In the present invention, the distance between the clamping assemblies 500 is equal to the distance between each group of adhesive rods 10, so as to ensure that when the clamping assemblies 500 clamp the adhesive rods 10, the midline of the clamping assemblies 11 is collinear with the axis of the adhesive rods 10, thereby ensuring better extraction of the adhesive rods 10. It should be noted that the clamping cylinder 600 can also be replaced by a hydraulic cylinder and an electric push rod, or other mechanical mechanisms can be used as other embodiments of the present invention. For example, a mechanical structure using a motor to drive a screw pair to achieve reciprocating linear motion can be adopted. The purpose of setting the clamping cylinder 600 is to drive the linkage beam 200 to reciprocate through the expansion and contraction of the clamping cylinder 600, thereby driving the clamping arms 510 to swing to achieve opening and closing.

[0029] As Figure 6 shown, in order to improve the clamping force of the clamping plate 520, anti-slip ridges 16 are provided on the working surface of the clamping plate 520. The surface of the clamping plate 520 connected to the clamping arm 510 is defined as the non-working surface, and the side away from the clamping arm 510 is defined as the working surface. The anti-slip ridges 16 are of the same length or width as the clamping plate 520. In other embodiments, the anti-slip ridges 16 can also be replaced by anti-slip bosses or intermittently arranged anti-slip ridges at intervals. The clamping plate 520 in this embodiment adopts a flat plate. In other embodiments, the working surface of the clamping plate 520 can also be set as a slightly curved arc surface, and the bending direction is towards the working surface direction.

[0030] Specifically, as Figure 1 and 5 shown, the clamping assembly 500 includes two oppositely arranged clamping arms 510. One end of the clamping arm 500 is connected to the linkage beam 200, and the middle part is hinged to the fixed beam 400. A clamping plate 520 is fixedly connected to the end of the clamping arm 500 away from the linkage beam 200. Under the drive of the clamping cylinder 600, the linkage beam 200 drives the clamping assembly 500 to open and close to clamp the embedded adhesive rod 10.

[0031] As Figure 2 shown, the linkage beam 200 of the present invention includes an upper linkage beam 210 and a lower linkage beam 220 that are oppositely arranged up and down. The upper linkage beam 210 and the lower linkage beam 220 are respectively connected to the corresponding upper and lower clamping cylinders 601 and 602 through connection seats 13 (see Figure 3 ), and are driven by the corresponding upper and lower clamping cylinders 601 and 602 to achieve reciprocating linear motion. Specifically: as Figure 3As shown in the figure, the upper clamping cylinder 601 and the lower clamping cylinder 602 are respectively located at both ends of the linkage beam 200, and the upper clamping cylinder 601 is located above the lower clamping cylinder 602. The upper clamping cylinder 601 drives the upper linkage beam 210, and the lower clamping cylinder 602 drives the lower linkage beam 220. In this embodiment, the piston rod of the upper clamping cylinder 601 is connected to the upper linkage beam 151 through the upper mounting seat 151, and the end far from the piston rod is connected to the lower linkage beam 220 through the upper fixing seat 141; the piston rod of the lower clamping cylinder 602 is connected to the lower linkage beam 220 through the lower mounting seat 152, and the end far from the piston rod is connected to the upper linkage beam 210 through the lower fixing seat 142. With such a design, the upper linkage beam 210 and the lower linkage beam 220 are pressed against each other to prevent deviation and dislocation during the sliding process. The piston rod of the clamping cylinder 600 and the mounting seat 15, and the end of the clamping cylinder 600 far from the piston rod and the fixing seat 14 are all hinged, and the center lines of the clamping cylinder 600, the fixing seat 14, the mounting seat 15, and the upper and lower linkage beams 210 and 220 are collinear. With such a design, it is ensured that the upper and lower linkage beams 210 and 220 will not be misaligned during the relative sliding process, thus ensuring the reliability and stability of the operation of the present invention.

[0032] In this embodiment, both the upper linkage beam 210 and the lower linkage beam 220 are channel steels, and the upper and lower channel steels are arranged back to back. In other embodiments, square tubes or I-beams can also be used instead of channel steels. In other embodiments, sliding wheels are provided at the bottom of the upper linkage beam 210, and sliding rails adapted to the sliding wheels are provided at the top of the lower linkage beam 220, so as to ensure that the upper linkage beam 210 and the lower linkage beam 220 are on the same straight line during relative movement. At the same time, sliding wheels are also provided at the bottom of the lower linkage beam 220, and sliding rails are also provided on the frame 1, so that cylinders with relatively small ejection forces can be used to displace the upper linkage beam 210 and the lower linkage beam 220.

[0033] As Figure 2 shown, the connecting seat 13 includes a connecting plate 130 and two connecting ear plates 131 fixed on the connecting plate 130. The two connecting ear plates 131 are arranged in parallel, and the clamping arm 510 is connected between the two connecting ear plates 131 through a connecting shaft 132. The clamping arm 510 is located between the two connecting ear plates 131. The above-mentioned fixing seat 14 and mounting seat 15 in this embodiment have the same structure as the connecting seat 13, and will not be elaborated here.

[0034] In this embodiment, one clamping arm 510 of each clamping assembly 500 is connected to the upper linkage beam 210, and the other clamping arm 500 is connected to the lower linkage beam 220. That is to say, the connecting plate 130 is fixedly connected to the upper linkage 210 or fixed to the lower linkage beam 220 as required. In order to make the clamping arms 510 lie in the same plane, the distances between the two connecting lugs 131 of each connecting seat 13 are equal. The distance between the two connecting lugs 131 is slightly greater than the thickness of the end of the clamping arm 510 connected to the connecting seat 13, and each connecting lug 131 located above lies in the same plane. Similarly, each connecting lug 131 located below also lies in the same plane. One clamping arm 510 in each clamping assembly 500 is connected to one linkage beam 200, and the other clamping arm 510 is connected to the other linkage beam 200. The linkage beam 200 is driven by the clamping cylinder 600, so as to realize the linkage of multiple clamping assemblies 500, and thus realize the simultaneous clamping of the glue sticks 10 by multiple clamping assemblies 500. As Figure 5 shown, the clamping arm 510 is L-shaped or C-shaped. Designed in this way, the clamping plate 520 can be closed with a relatively small thrust to clamp the glue stick 10. A through hole adapted to the connecting shaft 132 is provided at one end of the clamping arm 510.

[0035] As Figure 2 shown, the fixed beam 400 includes an upper fixed beam 410 and a lower fixed beam 420. The upper and lower fixed beams 410 and 420 are both fixed on the frame 1. The clamping arms 510 are arranged between the upper and lower fixed beams 410 and 420. In this embodiment, the upper and lower fixed beams 410 and 420 both adopt channel steels, and the channel steels are arranged back to back. One end of the clamping arm 510 is connected to the linkage beam, passes through the gap between the two channel steels, and is fixedly connected to the clamping plate 520. The clamping arm 510 is rotatably connected to the upper fixed beam 410 and the lower fixed beam 420 through a hinge shaft. The hinge shaft sequentially passes through the upper fixed beam 410, the clamping arm 510, and the lower fixed beam 420 from top to bottom. The clamping cylinder 600 drives the corresponding linkage beam 200. Driven by the linkage beam 200, the clamping arm 510 rotates around the hinge shaft, so as to realize the opening and closing of the clamping assembly 500. In other embodiments, the fixed beam 400 can be replaced by a steel plate or a steel pipe.

[0036] The drawing device 3 of this embodiment includes a drawing cylinder 310. The drawing cylinder 310 is fixedly installed on the frame 1 and is located at both ends of the fixed beam 300. When the rubber rod 10 is drawn out, after the clamping assembly 500 clamps the rubber rod 10, the piston rod of the drawing cylinder 310 extends and presses against the steel mold 12, and the drawing work is carried out with the steel mold 12 as the fulcrum. In other embodiments, the drawing cylinder 310 can also be replaced by other devices that can achieve linear reciprocating motion, such as a hydraulic cylinder or an electric push rod. The drawing cylinder 310 is fixed at both ends of the frame 1. One drawing cylinder 310 can be provided at one end, or two drawing cylinders 310 can be provided. When two drawing cylinders 310 are provided at one end, during operation, the two drawing cylinders 310 at both ends extend simultaneously and press against the steel mold 12, with the upper and lower parts of the steel mold 12 as the fulcrums, which is beneficial to the balance of force and ensures that the steel mold 12 will not be laterally tilted or inclined when the rubber rod 10 is drawn. In other embodiments, a backing plate can also be fixedly provided on the piston rod of the drawing cavity 310 to increase the contact area between the piston rod and the steel mold 12 and prevent damage to the steel mold 12.

[0037] To facilitate the process of drawing the rubber rod 10, moving wheels 7 are provided at the bottom of the frame 1. The frame 1 realizes lateral movement away from or towards the steel mold 12 through the moving wheels 7. To enable the sleeper embedded rubber rod 10 rapid drawing machine of the present invention to longitudinally displace along the length direction of the steel mold 12, the drawing machine of the present invention further includes a moving platform 4. The moving platform 4 is arranged below the frame 1, and the frame 1 is longitudinally moved by the movement of the moving platform 4.

[0038] See Figure 3 , the moving wheels 7 of this embodiment are arranged at the bottom of the frame 1 and on the top of the moving platform 4. The moving wheels 7 include rollers 701 and guide wheels 702. The guide wheels 702 are adapted to the guide rails 703 fixedly arranged at the top of the moving platform 4. Under the action of the drawing cylinder 310, the guide wheels 702 move along the guide rails 703 and realize the lateral linear movement of the frame 1 in cooperation with the rollers 701. The rollers 701 are in direct contact with the top of the moving platform 4. By using a guiding guide wheel 702, it not only meets the requirement of the linear movement of the frame 1, but also compensates for the shaking generated during the drawing process, preventing the guide wheels 702 from jamming or disengaging from the guide rails 703, thus ensuring the smooth progress of the drawing work and improving the reliability of the operation of the drawing machine of the present invention.

[0039] The mobile platform 4 includes a support plate 401, a bracket 402, and mobile rollers 403 located at the bottom end of the bracket 402. The support plate 401 is located at the top of the bracket 402 and is used to support the machine frame 1. The mobile rollers 403 are adapted to the mobile tracks 5 laid on the workshop floor and can move along the walking tracks 5. In other embodiments, the height of the bracket 402 is adjustable. Specifically, the bracket includes a leg 4021 and a bottom frame 4022. The leg 4021 is fixed on the bottom frame 4022. The leg 4021 is a screw rod, and a handwheel (not shown in the figure) is provided thereon. Screw sleeves corresponding to the screw rod 11 are fixed on both the cross beam of the bottom frame 4022 and the bottom of the support rod 401. When it is necessary to adjust the height of the mobile platform 4, the adjusting handwheel is rotated to screw the screw rod 11 into or out of the screw sleeve, thereby adjusting the height of the mobile platform 4, finely adjusting the height of the mobile platform 4, improving the convenience of use, and making the present invention applicable to concrete sleeper production lines of different heights.

[0040] The working process of the automatic drawing machine for the embedded rubber rod of the sleeper of the present invention is as follows: As Figure 5 shown, when the sleeper 11 in the steel mold 12 is formed and it is necessary to draw out the rubber rod 10, the drawing machine of the present invention is pushed to the position where the rubber rod 10 needs to be drawn out, and the moving clamping cylinder 600 is started. The clamping cylinder 600 drives the upper and lower linkage beams 410 and 420 to slide relative to each other, thereby driving the clamping plate 510 on the clamping arm 520 to clamp the rubber rod 10. Then, the intake valve of the drawing cylinder 310 is opened. The piston rod of the drawing cylinder 310 presses against the steel mold 12. With the steel mold 12 as the fulcrum, under the push of the drawing cylinder 310, the machine frame 1 drives the clamping device 2 to move along the guide rail 703 to the side away from the steel mold 12 until the rubber rod 10 is drawn out.

[0041] The automatic drawing machine for the embedded rubber rod of the sleeper of the present invention enables multiple clamping mechanisms 500 to be linked through the linkage beam 200, and thus multiple rubber rods 10 can be clamped at one time and multiple rubber rods 10 can be drawn out simultaneously, with high working efficiency, high automation degree, and labor and time saving.

[0042] Figure 7 is a schematic structural diagram of the high-efficiency production system for sleepers of the present invention. As Figure 7As shown in the figure, an efficient production system for sleepers provided by the present invention includes a concrete sleeper production line 17. A walking track 5 is laid on one side of the concrete sleeper production line 17. An automatic drawing machine for pre-embedded rubber rods of sleepers that can move along the walking track 5 is provided on the walking track 5. The automatic drawing machine for pre-embedded rubber rods of sleepers uses the automatic drawing machine for pre-embedded rubber rods of sleepers described above, and the automatic drawing machine for pre-embedded rubber rods of sleepers will not be repeated here. The walking track 5 is arranged parallel to the track direction of the concrete sleeper production line 17, which is convenient for moving the automatic drawing machine for pre-embedded rubber rods of sleepers to the required position. In this embodiment, all the pre-embedded rubber rods 10 on one steel mold or one sleeper can be drawn out at one time, with high efficiency, saving the time required for drawing out the pre-embedded rubber rods 10, thereby accelerating the production efficiency of concrete sleepers.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
