Description

Technical fields:

[0002] This invention relates to a device for separating slurry baffles during the railway sleeper production process. Background technology:

[0004] Before concrete pouring, steel strands and grout baffles need to be installed in the mold during railway sleeper production. Each grout baffle has 6-14 holes. Workers manually thread several steel strands through the holes in a stack of multiple grout baffles. At the pier head area, behind the pier head, workers lift the grout baffles and steel strands to the starting position of the trolley of the grout separating machine. The foremost grout baffle is placed in front of the trolley's baffle. The trolley moves forward, carrying the grout baffles and steel strands. Workers then separate the remaining grout baffles threaded onto the steel strands at a certain distance. The drawback of this method is that because the steel strands are in close contact with the grout baffles, manually separating the baffles is very labor-intensive, resulting in high work efficiency, inaccurate spacing between adjacent grout baffles, and high labor intensity. Summary of the Invention:

[0006] The technical problem to be solved by the present invention is to provide a slitting machine that can reduce the labor intensity of workers, improve work efficiency, and have precise spacing between baffle plates.

[0007] The above objective is achieved as follows: Similar to existing PCB depaneling machines, it also includes a frame with a track at the top. A winch is installed at the front end of the frame, and the wheels of the moving trolley are placed within the track. One end of the steel cable on the winch is fixed to the front end of the moving trolley, and the other end of the steel cable is fixed to the rear end of the moving trolley after passing through a pulley at the rear end of the frame. The moving trolley has grooves near its left and right edges, and the lower ends of two first movable baffles are inserted into the two grooves respectively. Two first fixed baffles are fixed on the trolley between the two movable baffles. The distance between the movable baffle and its adjacent fixed baffle is less than the width of the baffle plate.

[0008] The difference is that a fixed trolley is added, which is located behind the mobile trolley, and the wheels of the fixed trolley are placed in the track; fixed hooks are fixed on the left and right sides of the rear of the mobile trolley, and movable hooks that cooperate with the fixed hooks are provided on the left and right sides of the front of the fixed trolley. The two movable hooks are respectively installed on the left and right sides of the fixed trolley through shafts. The left side of the movable hook on the left side of the fixed trolley has a hook opening baffle extending to the left, and the right side of the movable hook on the right side of the fixed trolley has a hook opening baffle extending to the right; the opening of the fixed hook faces upward, and the opening of the movable hook faces downward.

[0009] Limit bearings are installed on the left and right sides of the track, and a limit baffle is fixed on the frame between the two tracks. The limit baffle is located in front of the limit bearing, and a limit block is fixed in the middle of the front end of the fixed trolley. The position of the limit block corresponds to that of the limit baffle.

[0010] The rear of the fixed trolley is provided with grooves near the left and right edges, and the lower ends of the two second movable baffles are respectively inserted into the two grooves. Two second fixed baffles are fixed on the fixed trolley between the two second movable baffles. The two second movable baffles and the fixed trolley directly in front of the two second fixed baffles are provided with several holes arranged in a front-back pattern. That is, the fixed trolley has four rows, each row including several holes arranged in a front-back pattern. Each hole is provided with a lifting lever. The lower ends of the four lifting levers in the same row are fixed on a lifting frame. The lifting frame is located below the frame. Each lifting frame is installed on the cylinder rod of each first hydraulic cylinder. A downwardly extending connecting frame is fixed at the bottom of the fixed trolley. The cylinder body of each first hydraulic cylinder is fixed on the connecting frame of the fixed trolley.

[0011] Several hydraulic stop levers are arranged in a left-right pattern at the rear end of the frame behind the fixed trolley. The lower ends of the hydraulic stop levers are fixed to the hydraulic stop lever frame, which is located below the frame. The hydraulic stop lever frame is connected to the cylinder rod of the second hydraulic cylinder, and the cylinder body of the second hydraulic cylinder is connected to the frame.

[0012] The advantages of this invention are as follows: First, several steel strands are manually threaded into the holes of a stack of multiple grout-blocking plates. At the pier head area, two sets of grout-blocking plates and steel strands are directly pushed onto the trolley. The two foremost grout-blocking plates are placed in front of the fixed baffle and the adjacent movable baffle of the moving trolley, respectively. The rearmost grout-blocking plates are placed between the movable baffle and the adjacent fixed baffle of the fixed trolley, separating these plates so that there is one grout-blocking plate between every two adjacent lifting levers. At this time, the lifting levers are in the lowered state. After the grout-blocking plates are separated, the lifting levers are raised. The moving trolley moves forward with the fixed trolley. When they reach the limit baffle of the frame, the limit block on the fixed trolley is blocked by the limit baffle on the frame. At this time, the limit block on the movable locking hook of the fixed trolley touches the limit bearing, causing the movable locking hook to flip, separating the fixed trolley from the moving trolley. The lifting levers descend sequentially from front to back at set intervals, thus separating the slurry baffles on the steel strand. Using this device reduces the labor intensity of workers, improves work efficiency, and ensures precise spacing between the slurry baffles. Attached image description:

[0020] The following is combined Figure 1-5 The present invention will be further described;

[0021] Similar to existing PCB separators, it also includes a frame 1, with a track 2 on top of the frame. A winch 3 is installed at the front end of the frame, and the wheels of the moving trolley 4 are placed inside the track. One end of the steel rope on the winch is fixed to the front end of the moving trolley, and the other end of the steel rope on the winch is fixed to the rear end of the moving trolley after passing through a pulley at the rear end of the frame. The moving trolley has grooves near its left and right edges, and the lower ends of two first movable baffles 41 are inserted into the two grooves respectively. Two first fixed baffles 42 are fixed on the trolley between the two movable baffles. The distance between the movable baffle and the adjacent fixed baffle is less than the width of the baffle plate.

[0022] The difference is that the length of the frame and track is extended so that the rear end of the frame and track is located at the pier head area 6, and a fixed trolley 5 is added. The fixed trolley is located behind the moving trolley, and the wheels of the fixed trolley are placed inside the track. Fixed locking hooks 43 are fixed on the left and right sides of the rear of the moving trolley, and movable locking hooks 51 that cooperate with the fixed locking hooks are provided on the left and right sides of the front of the fixed trolley. The two movable locking hooks are respectively installed on the left and right sides of the fixed trolley through shafts. A locking hook opening baffle 52 extending to the left is fixed on the left side of the movable locking hook located on the left side of the fixed trolley, and a locking hook opening baffle 52 extending to the right is fixed on the right side of the movable locking hook located on the right side of the fixed trolley. The opening of the fixed locking hook faces upward, and the opening of the movable locking hook faces downward.

[0023] Limit bearings 7 are installed on the left and right sides of the track, respectively. A limit baffle 8 is fixed on the frame between the two tracks, located in front of the limit bearings. A limit block 53 is fixed at the center of the front end of the fixed trolley, corresponding to the position of the limit baffle. The fixed locking hook of the moving trolley and the movable locking hook of the fixed trolley are connected together. The movement of the moving trolley drives the movement of the fixed trolley. When they reach the limit baffle of the frame, the limit block on the fixed trolley is blocked by the limit baffle on the frame. At this time, the locking hook opening baffle on the movable locking hook of the fixed trolley touches the limit bearing, and the locking hook opening baffle flips upward, causing the movable locking hook to flip. At this time, the fixed trolley and the moving trolley separate.

[0024] The rear of the fixed trolley is provided with grooves near the left and right edges, and the lower ends of the two second movable baffles 54 are respectively inserted into the two grooves. Two second fixed baffles 55 are fixed on the fixed trolley between the two second movable baffles. The two second movable baffles and the fixed trolley in front of the two second fixed baffles are provided with several holes arranged in a front-to-back pattern, that is, the fixed trolley has four rows, each row including several holes arranged in a front-to-back pattern. Each hole is provided with a lifting lever 56. The lower ends of the four lifting levers in the same row are fixed on a lifting frame 57. The lifting frame is located below the frame. Each lifting frame has a first hydraulic cylinder 58 below it. Each lifting frame is installed on the cylinder rod of each first hydraulic cylinder. A downwardly extending connecting frame 59 is fixed at the bottom of the fixed trolley. The cylinder body of each first hydraulic cylinder is fixed on the connecting frame of the fixed trolley.

[0025] Several hydraulic stop levers 9 are arranged horizontally at the rear end of the frame behind the fixed trolley. The steel strand and the baffle plate are located between two adjacent hydraulic stop levers. The lower ends of the hydraulic stop levers are fixed to the hydraulic stop lever frame 10, which is located below the frame. The hydraulic stop lever frame is connected to the cylinder rod of the second hydraulic cylinder 11, and the cylinder body of the second hydraulic cylinder is connected to the frame. Raising the hydraulic stop levers prevents the steel strand and the baffle plate from falling off the frame.

[0026] During operation, workers first thread several steel strands through the holes of a stack of multiple grout baffles. At the pier head area, two sets of grout baffles and steel strands are pushed directly onto the trolley. The two foremost grout baffles are placed in front of the fixed baffle and the adjacent movable baffle of the moving trolley, respectively. The grout baffles at the rear are placed between the movable baffle and the adjacent fixed baffle of the fixed trolley, separating these grout baffles so that there is one grout baffle between every two adjacent lifting levers. At this time, the lifting levers are in the lowered state. After the grout baffles are separated, the lifting levers are raised. The moving trolley moves forward with the fixed trolley. When they reach the limit baffle of the frame, the limit block on the fixed trolley is blocked by the limit baffle on the frame. At this time, the limit block on the movable locking hook of the fixed trolley touches the limit bearing, causing the movable locking hook to flip, and the fixed trolley separates from the moving trolley. The lifting levers descend sequentially from front to back at regular intervals, thus separating the baffle plates on the steel strands.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
