Description

Technical Field

[0001] The present invention belongs to the technical field of concrete sleeper production, and specifically relates to a device for automatically grouping prestressed steel wires of a sleeper, an automatic grouping and mold-filling system, and a method therefor. Background Art

[0002] When producing concrete sleepers by the pretensioning method, before the concrete is poured, the prestressed steel wires must be grouped according to the requirements of the drawings, then put into the mold and tensioned. After tensioning, fittings are installed and then the concrete is poured. In order to form multiple sleepers at one time to improve production efficiency, a plurality of baffles need to be placed in the sleeper forming steel mold to separate the mold. When grouping the prestressed steel wires, after passing the prestressed steel wires through the baffles and putting on stirrups, the baffles are manually placed in place. Since the length of the steel bar group is large and the weight is heavy, at least two people are required to pull a baffle at the same time and use measuring tools to place the baffle in place, and then return to place another baffle. Taking the example of forming 4 sleepers at one time in a sleeper forming steel mold, 8 baffles need to be arranged in the mold, and the workers need to make 4 round trips to place the baffles in place. If more sleepers are formed at one time, more baffles are required, resulting in high labor intensity of the workers, low work efficiency, and affecting the production progress.

[0003] For the grouped steel bar group, due to its long length and large weight, it is usually carried into the steel mold by the joint effort of multiple people. This method requires a large amount of labor and consumes a lot of physical strength to complete, with high labor intensity and low efficiency. Summary of the Invention

[0040] The following is combined with Figure 1 and 2 The technical solution of the present invention is further specifically described.

[0041] Embodiment 1: The present invention provides a sleeper prestressed steel wire braiding device, which is used to automatically place a plurality of baffles inserted on the prestressed steel wires in place according to the size of the sleeper forming steel mold. Figure 1 , Figure 2 and Figure 3 As shown, the prestressed steel wire braiding device of the sleeper includes a wire support platform 1, a group of prestressed steel wires to be braided are placed on the wire support platform 1, a group of prestressed steel wires 2 is usually not less than 8, a moving trolley 3 is arranged on the wire support platform 1, a track for the moving trolley 1 to move in a straight line is arranged on the wire support platform 1, a clamping mechanism 5 for preventing the baffle 4 from falling is arranged on the moving trolley 3, two baffles 4 form a group, and a plurality of stirrups 6 are arranged between a group of baffles 4, and the stirrups 6 are located on the outside of the prestressed steel wire group 2 to prevent the prestressed steel wire from shifting when pouring concrete sleepers, and the number of stirrups 6 is determined according to the sleeper manufacturing drawings. A limiting mechanism 7 is provided on the wire support platform 1 at a position corresponding to the steel mold for forming the sleeper, so that the baffle 4 falls from the moving trolley 3 under the action of the limiting mechanism 7 (two baffles 4 fall on one side, one of which is the tail end plate of the forming mold in the steel mold, and the other is the head end plate of another forming mold in the steel mold), and the remaining baffles contact the clamping block 9 under the action of friction to prevent falling, and then fall from the moving trolley 3 when they reach the next limiting mechanism 7. A steel mold can form multiple sleepers on one side separated by baffles 4. The baffle 4 is a metal plate, and a through hole is opened in the baffle 4 according to the arrangement mode and position of the prestressed steel wire in the drawing, so that the prestressed steel wire can pass through the baffle 4.

[0042] The wire support platform 1 includes a rectangular frame composed of two parallel longitudinal beams and cross beams connected at both ends of the longitudinal beams. A plurality of legs 101 are arranged at the bottom of the rectangular frame. The longitudinal beams are made of 80 channel steel, and the longitudinal beams serve as tracks 102 for the mobile trolley 3. When in use, the first baffle 4 is fixed to one end of the wire support platform 1 by a fixing mechanism to prevent the prestressed steel wire from moving with the mobile trolley during operation. The fixing mechanism of this embodiment is that the top of the end plate of one end of the wire support platform 1 is higher than the track 102, thereby limiting the first baffle 4 to prevent the first baffle 4 from moving during operation. In other embodiments, the first baffle 4 can also be fixed by combining bolts and a fixing plate. The fixing plate is installed at one end of the wire support platform 1 by bolts, and the fixing plate presses the first baffle 4 under the action of the bolts to fix it.

[0043] As other embodiments of the present invention not shown in the drawings: In order to conveniently pass one end of the prestressed steel wire through the baffle 4 and perform upset anchoring operation after passing through the baffle 4, an operating platform with the same height as the wire supporting platform 1 is arranged on one side of the wire supporting platform 1. After threading all the baffles 4 onto each steel wire and performing upset anchoring on the operating platform, then place all the baffles 4 and the steel wires at one end of the steel wire on the wire supporting platform 1.

[0044] The moving trolley 3 of this embodiment includes a base 301 and a driving mechanism that provides power for the movement of the moving trolley. A roller 305 adapted to the track is arranged at the bottom of the base 301. The base 301 of this example is a steel structure frame. The driving mechanism of this example includes an electric winch 302, a traction steel cable 303, and a pulley 304. A plurality of pulleys 304 are installed on the support frame of the wire supporting platform 1 through pulley seats. The traction steel cable 303 bypasses the pulley 304 on the wire supporting platform and the pulley on the moving trolley 3 and is connected to the electric winch 302. The rotation of the electric winch 302 drives the movement of the moving trolley 3 through the traction steel cable 303. In other embodiments, a motor can also be used to provide power, and the driving mode of the sprocket and chain transmission can be used to make the moving trolley 3 move.

[0045] The clamping mechanism 5 includes a clamping arm 501 and a bracket 502. The bracket 502 is fixed on the base 301 of the moving trolley 3. Two oppositely arranged clamping arms 501 are arranged on the bracket 502. Both clamping arms 501 are rotatably arranged on the bracket 502 through a pin shaft 8. An inwardly facing clamping block 9 is arranged at one end of both clamping arms 501. During use, the first baffle 4 abuts against the inner surface of the clamping block 9. By arranging the clamping block 9 and cooperating with the clamping arm 501, the baffle 4 is prevented from falling off the moving trolley 3.

[0046] As Figure 4 shown, each clamping arm 501 includes an upper clamping arm plate 5011 and a lower clamping arm plate 5012. The upper clamping arm plate 5011 and the lower clamping arm plate 5012 have the same structure. A stepped partition tube 503 is arranged between the two vertically arranged clamping arm plates. The pin shaft 8 is arranged in the partition tube 503, and its two ends extend out of the corresponding clamping arm plates and are hinged to the bracket 502. The pin shaft 8 is locked by a locking pin or a nut. In this embodiment, the nut and spring washer method is used to lock the pin shaft 8.

[0047] Next, taking the upper clamping arm plate 5011 as an example, the structure of the clamping arm plate 501 will be described in detail. Specifically: As Figure 5As shown in the figure, the upper clamping arm plate 5011 includes a clamping working part 5011A and a clamping release part 5011B. Both the clamping working part 5011A and the clamping release part 5011B are rectangular structures. The clamping release part 5011B is located outside the clamping working part 5011A, and the two are arranged in parallel. The clamping working part 5011A and the clamping release part 5011B are connected by a connecting part 5011C. The connecting part 5011C is inclined. An installation hole 10 is opened at the connection between the connecting part 5011C and the clamping working part 5011A. The clamping block 9 is fixed at one end of the clamping working part 5011A away from the connecting part 5011C. The clamping block 9 and the clamping working part 5011A are an integral structure. When installed, the clamping block 9 is installed towards the inner side of the moving trolley 3. The clamping working part 5011A, the clamping release part 5011B and the connecting part 5011C are also an integral structure. For the convenience of processing and to ensure the strength of the upper clamping arm plate 5011, the upper clamping arm plate 5011 is cut from a steel plate. In order to ensure that the clamping arm can rotate around the pin shaft 8, the diameters of the tube heads at both ends of the partition tube 503 are larger than the diameter of the tube body. Limiting platforms are formed at the connections between the tube heads at both ends and the tube body. The lengths of the tube heads at both ends of the partition tube 503 are greater than the thickness of the clamping arm plate 501. When installed, the upper tube head of the partition tube 503 is inserted into the installation hole 10 of the upper clamping arm plate 5011, and its lower tube head is inserted into the installation hole 10 of the lower clamping arm plate 5012. The end faces of the tube heads at both ends of the partition tube 503 are in contact with the corresponding parts of the support 502, so that there is a gap between the clamping arm plate 501 and the support 501, avoiding the influence of the support 501 on its rotation and ensuring the reliability of the work.

[0048] A connecting plate is provided between the working parts of the upper clamping arm plate 5011 and the lower clamping arm plate 5012, and a return spring 12 is arranged between the connecting plate 11 and the support 502.

[0049] See Figure 4 , the support 502 includes a vertically arranged support plate 5021 and a horizontally arranged support rod 5022. The bottom of the support plate 5021 is fixed at one end of the base 301. A relief groove for avoiding the prestressed steel wire group is opened at the upper end of the support plate 5021 and extends downward. Two support rods 5022 arranged vertically are fixed on both sides of the relief groove. The clamping arm is hinged between the two support rods 5022 arranged vertically, that is, the upper clamping arm plate 5011 is located below the upper support rod, and the lower clamping arm plate 5012 is located above the lower support rod. A fixing block is arranged between the two support rods 5022 arranged vertically. One end of the return spring 12 is connected to the connecting plate 11, and the other end is connected to the fixing block.

[0050] The limiting mechanism 7 includes limiting columns 701 relatively arranged on both sides of the wire support platform 1, and the limiting columns 701 are installed on the fixed plate 702, and the fixed plate 702 is connected to the wire support platform 1. When the moving trolley 3 carries the baffle 4 through the limiting mechanism 7, the clamping release part 5011B located on the outside of both sides of the moving trolley 3 is tightened inward around the pin shaft 8 under the action of the two limiting columns 701, and then its clamping working part is expanded, so that the baffle 4 is freed from the restriction of the block 9, and thus falls from the moving trolley 3. As the baffle 4 falls, the stirrups 6 also fall (because the plane shape formed by the stirrups is much smaller than the baffle). When the clamping release part 5011B leaves the limiting column 701, under the action of the reset spring 12, the clamping arm 5 is reset, and the block 701 restricts the baffle adjacent to the falling baffle to prevent it from falling. The outer side of the limiting column 701 is covered with a limiting sleeve 703. The limiting sleeve 703 can rotate around the limiting column 701, so it plays a role in protecting the limiting column. The fixing plate 702 is provided with an oblong hole arranged horizontally along the wire support platform 1. The bottom end of the limiting column 701 is installed in the oblong hole and locked by a nut. The oblong hole is provided to facilitate the adjustment of the distance between the limiting column 701 and the wire support platform 1. In other embodiments, the opening and closing of the clamping arm 5 can also be controlled by a cylinder or a stepping motor. In this case, the limiting mechanism 7 is a sensor.

[0051] In other embodiments, Figure 5 As shown, in order to enable the clamping release portion 5011B of the clamping arm 5 to cooperate smoothly with the limiting mechanism 7, the outer sides of the two clamping arm plates 501 away from the clamping block 9 are chamfered, and the angle of the chamfer 13 is 30° to 60°. The chamfer 13 plays a guiding role, so that the clamping arm 5 can cooperate smoothly with the limiting sleeve 703.

[0052] The working process and principle of the automatic grouping device for prestressed steel wires of sleepers in this embodiment are as follows: Figure 2 When in use, one end of a group of prestressed steel wires is passed through the through holes on all the required baffles 4, and one end of all the steel wires is anchored to the pier head. Stirrups 6 are arranged between a group of baffles 4. The first baffle 4 is fixed at one end of the wire support platform. The stirrups 6 and the remaining baffles 4 move along the prestressed steel wire with the moving trolley. When passing through the limiting mechanism 7, under the action of the limiting mechanism 7, the clamping arm 5 and the block 9 restrict the baffle 4, and then the baffle 4 falls from the moving trolley 3. When passing through the position of the next limiting mechanism 7, the two baffles adjacent to the fallen baffle fall from the moving trolley 3 until all the baffles 4 are placed in the corresponding positions. The baffles 4 are automatically put in place. After the prestressed steel wire group that has been grouped is put into the mold, the next group of prestressed steel wires is ready, and the moving trolley 3 returns to group the next group of prestressed steel wires.

[0053] Example 2: See Figure 6, the present invention also provides an automatic grouping and molding system for prestressed steel wires of sleepers, which includes the automatic grouping device 100 of prestressed steel wires of sleepers in Embodiment 1, a discharging device 200, and a conveying device 300. The conveying device 300 is arranged on one side of the steel mold 400, and on the other side of the conveying device 300 is the grouping device 100. The height of the conveying device 300 is less than that of the grouping device 100, and the height difference between the two is 50 - 60 centimeters. The conveying device 300 is a chain conveyor. The discharging device 200 is arranged on the side of the grouping device 100 away from the conveying device 300. A steel wire storage area 500 is arranged on the side of the grouping device 100 away from the conveying device 300. Placing the prestressed steel wires cut to a fixed length in the steel wire storage area 500 is convenient for use.

[0054] As Figure 7 shown, the discharging device 200 of this embodiment adopts the following structure: The discharging device includes a pushing rod 210, a pushing arm 220, and a power mechanism for driving the pushing rod 210 to push materials. The power mechanism uses a cylinder 230. The pushing rod 210 is a steel pipe, and its length is less than the length of the prestressed steel wire group 2. One side of the pushing rod 210 is fixedly connected to one end of the pushing arm 220. The other end of the pushing arm 220 is hinged on the wire supporting table 1. Specifically: A hinge seat 240 is arranged on the wire supporting table 1, and the pushing arm 220 is hinged to the hinge seat 240 through a pin. The bottom end of the cylinder 230 is installed on the ground or the wire supporting table 1, and its telescopic rod output end is connected to the middle of the pushing arm 220. By the extension of the cylinder 230, the pushing arm is driven to rotate around the pin, so as to push the grouped prestressed steel wire group 2 onto the conveying device 300. The pushing rod 210 is strip-shaped, and a plurality of pushing arms 220 are arranged at intervals on its non-working surface (the side away from the steel wire group). Each pushing arm 220 is hinged to a cylinder 230. The pushing arm 220 includes two oppositely arranged pushing arm plates. The pushing arm plates are in a U shape, and the length of one side arm rod is greater than that of the other side arm rod. The short arm rod is hinged to the hinge seat 240, and the long arm rod is fixedly connected to the pushing rod 210. The piston end of the cylinder 230 is connected between the connecting rods of the two pushing arm plates through a bolt assembly. The discharging device 200 with the above structure is hinged to the wire supporting table 1, and has a small volume and is convenient for storage, and does not affect the work of the wire supporting table 1 when not discharging. In this embodiment, the air inlet valve of the cylinder 230 adopts an electromagnetic valve, and each air inlet valve is electrically connected to the controller, which is convenient for controlling the air intake of the cylinder 230, so as to control the discharging of the discharging device 200.

[0055] Embodiment 3: This embodiment provides an automatic grouping and molding method for prestressed steel wires of sleepers using the automatic grouping and molding system for prestressed steel wires of sleepers in Embodiment 2, which specifically includes the following steps:

[0056] (1) According to the requirements of the drawing, take a group of prestressed steel wires from the steel wire storage area 500 and place them on the wire supporting table 1;

[0057] (2) Thread all the required baffles 4 and stirrups 6 through one end of the prestressed steel wires, and upset and anchor each steel wire.

[0058] (3) Fix the first baffle 4 to one end of the wire supporting table 1 through the fixing mechanism. The first and last baffles 4 do not move with the movement of the moving trolley 3.

[0059] (4) Start the moving trolley 3 so that the moving trolley 3 moves from the other end of the wire supporting table 1 to the baffle 4 and stops. Press the clamping arm 501 so that the clamping mechanism 5 clamps the remaining baffles.

[0060] (5) Start the moving trolley 3 again. At this time, the moving trolley 3 drags the baffles forward to the limiting mechanism 7. Under the action of the limiting mechanism 7, the baffles 4 sequentially fall onto the wire supporting table 1, completing the automatic placement of the baffles 4 in place. Then upset and anchor the other ends of all the prestressed steel wires.

[0061] (6) Start the unloading mechanism 200. Under the action of the pushing rod 210, the grouped prestressed steel wire groups 2 are woven and fall into the conveying device 300.
