Description

Technical Field

[0001] The present application relates to the technical field of sleeper production, and in particular to a screwing device for spiral ribs of a sleeper casing. Background Art

[0002] Sleepers are generally made by pouring concrete materials into a mold, waiting for it to solidify to form a concrete block, and then demolding it. The sleepers are prefabricated in advance and transported to the railway construction site for sleeper fixation and construction. In order to subsequently install and position other components on the sleepers, it is necessary to set sleeves at the preset positions of the sleepers during the pouring and shaping process of the sleepers.

[0003] In order to screw other installed and positioned components into or out of the sleeve, a spiral rib sleeve is generally preset on the sleeper. The spiral rib sleeve is a sleeve with spiral ribs arranged outside a truncated cone shell. The shape of the spiral rib corresponds to the shape of the sleeve, with a large diameter at one end and a small diameter at the other end. The whole is truncated cone-shaped. A groove is arranged on the sleeve shell so that the sleeve can rotate in the spiral rib.

[0004] The existing production of spiral rib casing is to manually screw the spiral rib onto the casing, which has low work efficiency. In addition, the manual screwing method often results in the situation of not tightening or screwing to a dead state. Not tightening can easily cause the casing to fall off, and screwing to a dead state will cause the casing to be unable to rotate later. The spiral rib casing in both cases needs to be reworked, which seriously affects the production efficiency of the spiral rib casing. Summary of the invention

[0005] The present application provides a device for screwing spiral ribs of a sleeper casing, so as to solve the problem of low production efficiency of spiral rib casings produced manually.

[0006] The present application provides a screwing mechanism for spiral reinforcement of a sleeper casing, comprising a conveyor line, a fixing device, a lifting electric cylinder, a screwing motor and a screwing sleeve;

[0008] The lifting electric cylinder is arranged above the fixing device, and the movable end of the lifting electric cylinder is connected to the screwing motor, and the lifting electric cylinder can drive the screwing motor to move up and down;

[0009] The output shaft of the screwing motor is connected to the screwing sleeve to drive the screwing sleeve to rotate.

[0010] Optionally, the conveyor line is a chain plate assembly line, and positioning columns are provided on the chain plates, and the positioning columns are used to place spiral rib sleeves.

[0011] Optionally, it also includes a guide column; one end of the guide column is connected to the screw sleeve, and the other end can slide through the mounting plate of the lifting electric cylinder.

[0012] Optionally, the fixing device includes a fixing cylinder and a fixing jaw; the output end of the fixing cylinder is connected to the fixing jaw to drive the fixing jaw to clamp or loosen the spiral rib sleeve.

[0013] Optionally, it also includes a return device; the return device is arranged on both sides of the conveying line, and the spiral rib sleeve is returned to the position of the fixing device after being returned by the return device.

[0014] Optionally, the return device includes a return cylinder and a return guide plate; the movable end of the return cylinder is connected to the return guide plate, and the return guide plates on both sides of the conveying line return the spiral rib sleeve to the right position.

[0018] In actual application, when the conveyor line transports the spiral rib sleeve to the position of the fixing device, the conveyor line stops moving, the fixing device clamps the spiral rib sleeve, and then the lifting electric cylinder arranged above the fixing device is started, driving the screwing motor and the screwing sleeve to descend, so that the screwing sleeve clamps the spiral rib sleeve, and finally the screwing motor is started to drive the screwing sleeve to rotate, so that the spiral rib is screwed onto the sleeve. After the screwing is completed, the screwing sleeve is lifted and the conveyor line is started. The mechanized screwing equipment has high screwing efficiency, and the screwing force can be set according to the actual situation to ensure that the screwing force of the spiral rib is consistent, avoid a lot of rework, and improve the production efficiency of the spiral rib sleeve.

[0032] In order to solve the problem of low production efficiency of spiral reinforcement casing produced by manual method. Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the present application, a screwing mechanism for the spiral reinforcement of a sleeper casing is provided, comprising a conveyor line 1, a fixing device 2, a lifting electric cylinder 3, a screwing motor 4 and a screwing sleeve 5; the fixing device 2 is arranged on both sides of the conveyor line 1 to clamp the spiral reinforcement casing transported on the conveyor line 1; the lifting electric cylinder 3 is arranged above the fixing device 2, and the movable end of the lifting electric cylinder 3 is connected to the screwing motor 4, and the lifting electric cylinder 3 can drive the screwing motor 4 to lift and lower; the output shaft of the screwing motor 4 is connected to the screwing sleeve 5 to drive the screwing sleeve 5 to rotate.

[0033] The conveyor line 1 is used for conveying spiral rib sleeves, and during the conveying process, the conveyor line 1 can stop moving so that the spiral rib sleeves can be screwed when stopped. The fixing device 2 is arranged on both sides of the middle section of the conveyor line 1, and a detection sensor is arranged on the fixing device 2, which can detect the spiral rib sleeves. For example, a photoelectric sensor is used to detect whether there are spiral rib sleeves being conveyed on the conveyor line 1.

[0034] The lifting electric cylinder 3 is arranged above the fixing device 2 through a mounting frame and a mounting plate. For example, a mounting frame is arranged around the fixing device 2, and a mounting plate for mounting the lifting electric cylinder 3 is arranged on the top of the mounting frame, so that the lifting electric cylinder 3 is above the fixing device 2. The screwing motor 4 is arranged at the movable end of the lifting electric cylinder 3 to drive the screwing motor 4 to move up and down, so that the screwing sleeve 5 clamps or releases the spiral rib sleeve. The screwing sleeve 5 is semicircular and is provided with a groove clamped with the spiral rib inside to drive the spiral rib to rotate relative to the sleeve.

[0035] A screwing mechanism for spiral reinforcement of a sleeper casing provided in an embodiment of the present application comprises a conveyor line 1, a fixing device 2, a lifting electric cylinder 3, a screwing motor 4 and a screwing sleeve 5; the fixing device 2 is arranged on both sides of the conveyor line 1 to clamp the spiral reinforcement casing transported on the conveyor line 1; the lifting electric cylinder 3 is arranged above the fixing device 2, and the movable end of the lifting electric cylinder 3 is connected to the screwing motor 4, and the lifting electric cylinder 3 can drive the screwing motor 4 to lift and lower; the output shaft of the screwing motor 4 is connected to the screwing sleeve 5 to drive the screwing sleeve 5 to rotate.

[0036] In actual application, when the conveyor line 1 transports the spiral rib casing to the position of the fixing device 2, the conveyor line 1 stops moving, the fixing device 2 clamps the spiral rib casing, and then the lifting electric cylinder 3 arranged above the fixing device 2 is started, driving the screwing motor 4 and the screwing sleeve 5 to descend, so that the screwing sleeve 5 clamps the spiral rib casing, and finally the screwing motor 4 is started to drive the screwing sleeve 5 to rotate, so that the spiral rib is screwed onto the casing, and after the screwing is completed, the screwing sleeve 5 is lifted and the conveyor line 1 is started. The mechanized screwing equipment has high screwing efficiency, and the screwing force can be set according to the actual situation to ensure that the screwing force of the spiral rib is consistent, avoid a large amount of rework, and improve the production efficiency of the spiral rib casing.

[0037] See also Figure 4 , which is a schematic diagram of the partial structure of a screwing mechanism for the spiral ribs of a sleeper casing provided in an embodiment of the present application.

[0038] In order to ensure that the conveyor line 1 can smoothly transport the spiral rib casing. Figure 4 As shown, in some embodiments of the present application, the conveyor line 1 is a chain plate assembly line, and a positioning column 11 is provided on the chain plate, and the positioning column 11 is used to place the spiral rib sleeve.

[0039] The chain plate assembly line is a flat conveyor, which is suitable for larger workpieces to be operated and conveyed on it. Fixtures can also be installed on the chain plate, which has a large load and runs smoothly. The workpiece can be directly placed on the line for conveying. A positioning column 11 is arranged on the chain plate of the conveyor line 1, and the positioning column 11 is fixedly arranged on the chain plate for placing the spiral rib sleeve.

[0040] See also Figure 5 , which is a schematic diagram of the top view of the structural structure of a screwing mechanism for the spiral ribs of a sleeper casing provided in an embodiment of the present application.

[0041] See also Figure 6 , which is a front view structural schematic diagram of a screwing mechanism for the spiral reinforcement of a sleeper casing provided in an embodiment of the present application.

[0042] To ensure that the lifting electric cylinder 3 can drive the screw sleeve 5 to lift vertically, the screw sleeve 5 can accurately clamp the spiral rib sleeve. Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in some embodiments of the present application, the screwing mechanism further includes a guide column 6; one end of the guide column 6 is connected to the screwing sleeve 5, and the other end can slide through the mounting plate of the lifting cylinder 3.

[0043] In actual applications, the guide column 6 is cylindrical, and one end is connected to the screwing sleeve 5. For example, a connecting plate is arranged between the screwing sleeve 5 and the output shaft of the screwing motor 4, and one end of the guide column 6 is arranged on the connecting plate. The other end of the guide column 6 passes through the mounting plate of the lifting electric cylinder 3 and can slide in the vertical direction relative to the mounting plate of the lifting electric cylinder 3, that is, to ensure that the screwing sleeve 5 can move in the vertical direction.

[0044] like Figure 3 As shown, in some embodiments of the present application, the fixing device 2 includes a fixing cylinder 21 and a fixing jaw 22; the output end of the fixing cylinder 21 is connected to the fixing jaw 22 to drive the fixing jaw 22 to clamp or loosen the spiral rib sleeve. In actual application, a fixing cylinder 21 is provided on both sides of the conveyor line 1, and the two fixing cylinders 21 move synchronously. The fixing jaw 22 is provided on the telescopic rod of the fixing cylinder 21, and the spiral rib sleeve is clamped or loosened by the two fixing jaws 22. Since the spiral ribs on the outside of the spiral rib sleeve have a certain elasticity, even after a part of the spiral ribs with a larger diameter are clamped, the spiral ribs with a smaller diameter can still be clamped and screwed by the screwing sleeve 5.

[0045] In order to ensure that the spiral rib sleeve is in a vertical state when it is transported to the fixing device 2, it is convenient for clamping and screwing. Figure 5 As shown, in some embodiments of the present application, the return device 7 includes a return cylinder 71 and a return guide plate 72; the movable end of the return cylinder 71 is connected to the return guide plate 72, and the return guide plates 72 on both sides of the conveying line 1 return the spiral rib sleeve.

[0046] In actual application, a return cylinder 71 is provided on both sides of the conveyor line 1. The two return cylinders 71 move synchronously, and the return guide plate 72 is provided on the telescopic rod of the return cylinder 71. By setting the distance between the two return guide plates 72, the spiral rib sleeve passing through the two return guide plates 72 can be kept in a vertical state. If the spiral rib sleeve is in an inclined state, after being conveyed along the two return guide plates 72 with a fixed distance, the spiral rib sleeve will be converted into a vertical state due to the extrusion of the return guide plates 72 on both sides.

[0047] After the spiral rib sleeve is screwed, it is picked up by a robot on one side of the conveyor line 1 and placed at the next station, for example, the qualified product conveyor line, to be transported to the installation station. In order to detect whether the spiral rib sleeve meets the requirements after screwing, especially when it is not screwed in place, resulting in the height of the spiral rib sleeve being higher than the normal height. Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in some embodiments of the present application, the screwing mechanism also includes an ultra-high detection device 8; the ultra-high detection device 8 includes a laser transmitter 81 and a laser receiver 82 respectively arranged on both sides of the conveyor line 1; the laser receiver 82 is used to receive the laser emitted by the laser transmitter 81.

[0048] By arranging an ultra-high detection device 8 on the conveyor line 1, the ultra-high detection device 8 is located between the fixing device 2 and the manipulator (the manipulator for grabbing qualified products), the spiral rib casing is screwed and then transported to the ultra-high detection device 8, the ultra-high detection device 8 includes a laser emitter 81 and a laser receiver 82, and by arranging the laser emitter 81 on one side of the conveyor line 1 and setting the height of the laser emission, and arranging a laser receiver 82 for receiving the laser on the other side of the conveyor line 1, if the spiral rib casing passing between the laser emitter 81 and the laser receiver 82 exceeds the required height, the laser emitted by the laser emitter 81 will be blocked, so that the laser receiver 82 does not receive the laser emitted by the laser emitter 81, and the manipulator arranged on one side of the conveyor line 1 gives up clamping the ultra-high spiral rib casing, and the ultra-high spiral rib casing unit is transported on the conveyor line 1.

[0049] In order to collect the super high unqualified spiral reinforcement casing, such as Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of the present application, the screwing mechanism further includes a recovery box 9, which is arranged at the end of the conveying line 1 to recover the spiral rib casing that is too high after screwing. The recovery box 9 is arranged at the end of the conveying line 1. After the spiral rib casing that exceeds the fixed requirement in height is conveyed to the end of the conveying line 1, due to gravity factors, the unqualified spiral rib casing automatically detaches from the conveying line 1 and falls into the recovery box 9.

[0050] like Figure 1 , Figure 5 and Figure 6 As shown, the screwing mechanism for the spiral reinforcement of the sleeper casing provided in the embodiment of the present application includes a pneumatic box 101 and a control cabinet 102; the pneumatic box 101 is connected to the fixed cylinder 21 and the return cylinder 71 to provide high-pressure air. The control cabinet 102 is used to control the start or stop of the conveying line 1, the fixed cylinder 21, the lifting electric cylinder 3, the screwing motor 4 and the return cylinder 71.

[0051] It can be seen from the above technical scheme that a screwing mechanism for the spiral rib of a sleeper casing provided in an embodiment of the present application comprises a conveyor line 1, a fixing device 2, a lifting electric cylinder 3, a screwing motor 4 and a screwing sleeve 5; the fixing device 2 is arranged on both sides of the conveyor line 1 to clamp the spiral rib casing transported on the conveyor line 1; the lifting electric cylinder 3 is arranged above the fixing device 2, and the movable end of the lifting electric cylinder 3 is connected to the screwing motor 4, and the lifting electric cylinder 3 can drive the screwing motor 4 to lift and lower; the output shaft of the screwing motor 4 is connected to the screwing sleeve 5 to drive the screwing sleeve 5 to rotate.

[0052] In actual application, when the conveyor line 1 transports the spiral rib casing to the position of the fixing device 2, the conveyor line 1 stops moving, the fixing device 2 clamps the spiral rib casing, and then the lifting electric cylinder 3 arranged above the fixing device 2 is started, driving the screwing motor 4 and the screwing sleeve 5 to descend, so that the screwing sleeve 5 clamps the spiral rib casing, and finally the screwing motor 4 is started to drive the screwing sleeve 5 to rotate, so that the spiral rib is screwed onto the casing, and after the screwing is completed, the screwing sleeve 5 is lifted and the conveyor line 1 is started. The mechanized screwing equipment has high screwing efficiency, and the screwing force can be set according to the actual situation to ensure that the screwing force of the spiral rib is consistent, avoid a large amount of rework, and improve the production efficiency of the spiral rib casing.

[0053] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
