Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated production of double-block sleepers, and more specifically to the technical field of mold destacking and turning tooling. Background Art

[0002] With the development of high-speed railway technology, various new types of ballastless track, using concrete or asphalt mixtures instead of ballast tracks, are being developed to improve track stability and smoothness while significantly reducing maintenance workload. Ballastless track has been extensively deployed on newly constructed high-speed railway lines, achieving excellent technical and economic benefits.

[0003] In the construction process of ballastless high-speed railway, double-block precast concrete sleepers are the most commonly used. In the production process of double-block precast concrete sleepers, the mold needs to be flipped before demoulding. From the current investigation of the mold flipping methods of various sleeper prefabrication companies, it was found that most of them still use the traditional mechanical gear cylinder lock flipping method, which undoubtedly brings greater risks to safety and the appearance quality of sleepers. Some companies also use the fixed boom gantry flipping method. Although it can guarantee the appearance quality of sleepers to a certain extent, it still poses a greater safety risk. At present, cylinder telescopic fixed booms are mostly used for mold flipping. Since the device requires manual operation and has a greater safety risk, the existing process is time-consuming and labor-intensive. Existing patents disclose the technology:

[0004] The patent with publication number CN111169958A and patent name "A sleeper mold flipping device" discloses the following content: it includes a linear track and a trolley that moves along the length direction of the linear track. The trolley is used to transport the sleeper mold. The trolley is provided with a lifting mechanism for lifting the sleeper mold: a longitudinal beam is arranged above the linear track, and both ends of the longitudinal beam are provided with a hanger, and a telescopic cylinder that drives the hanger to reciprocate along the length direction of the longitudinal beam. A rotating motor is provided at the lower end of the hanger, and a splint is installed on the driving shaft of the rotating motor, and shaft sleeves are provided at both ends of the splint; the splints at both ends are driven by the telescopic cylinder to move closer to each other, so that their shaft sleeves are respectively mounted on the end shafts at both ends of the sleeper mold to achieve grasping, and then the splint is driven to rotate by the rotating motor.

[0005] On the premise of ensuring mold flipping safety, quality, energy saving and environmental protection, the existing technology and the above patents have the following problems:

[0006] 1. In the prior art, although a fixed hanger flipping device is used, the device is a door-type mechanism design. When the mold is flipped, the telescopic cylinder drives the hanger to reciprocate along the length direction of the longitudinal beam, causing a lateral force to act on the mold, resulting in poor stability and easy falling off, posing a safety hazard.

[0007] 2. Under continuous production conditions, the device requires the trolley to transport the mold back and forth multiple times, and can only transport one set of molds each time. The mold turning efficiency is low, and it is time-consuming and energy-consuming, which poses problems in energy conservation and environmental protection. Utility Model Content

[0008] The purpose of the present invention is to solve the above technical problems and provide a mold disassembly and turnover tooling, which can achieve fast and high efficiency while ensuring the appearance of concrete and the quality of sleeper molds.

[0009] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0010] The utility model provides a mold destacking and turning tool, which includes a fixed beam, a turning trolley, a turning device, a lifting device, a grabbing assembly, and an electric control system. The turning trolley is slidably arranged on the fixed beam, the turning device is arranged on the turning trolley, a corner device connected to the turning device is arranged at the bottom of the lifting device, the grabbing assembly is located on the lifting device, and a position sensing sensor is arranged on the fixed beam.

[0011] The tipping trolley, the tipping device, the lifting device, the grabbing assembly, the hydraulic station, and the position sensing sensor are all connected to the electronic control system signal.

[0012] Specifically, an intelligent system automatically activates the control system once the mold is in place. The electronic control system controls the lowering (or raising) of the lifting mechanism, triggering the position sensor. The position of the angler corresponds to the mold. The opening and closing cylinder extends, triggering the position sensor. The hydraulic system controls the raising (or lowering) of the lifting mechanism, triggering the position sensor. This causes the lifting mechanism to lift the mold to the flip position, activate the angler to rotate 180 degrees, and the mold is in place. Once the mold is moved and flipped, the flip carriage automatically adjusts to its initial position to facilitate the next flip operation.

[0013] The technical features of the above technical solution are reflected in easy-to-understand theories and simple processes. The entire mold turning process is different from the existing technology. It not only improves the efficiency of mold disassembly and mold turning, but more importantly, greatly reduces the safety risks in the production process. At the same time, it ensures the appearance quality of the sleeper concrete. It is creative and worthy of promotion and application.

[0014] In one embodiment, the fixed beam includes two cross beams arranged in parallel, and a wheel groove is provided on each cross beam along the length direction, and the tipping trolley is clamped in the wheel groove.

[0015] In one embodiment, the flipping trolley includes a square frame and two sets of running wheel assemblies arranged on both sides of the bottom of the square frame. Each set of running wheel assemblies is respectively engaged in the corresponding wheel groove, and a running drive mechanism for driving the corresponding running wheel assembly is provided on both sides of the square frame.

[0016] In one embodiment, the travel drive mechanism is a travel motor, and each group of travel wheel assemblies includes at least two travel wheels, one of which is a driving wheel and the other are driven wheels, and the driving wheel is connected to the output shaft of the travel motor.

[0017] In one embodiment, there are two turning devices, which are arranged in parallel on a turning trolley. The turning trolley is provided with a distance adjustment device for adjusting the distance between the two turning devices.

[0018] In one embodiment, the distance adjustment device includes two groups of opening and closing cylinders respectively provided on the tipping trolley, each group of opening and closing cylinders includes two hydraulic cylinders and a hydraulic station, which provides power for the lifting device.

[0019] In one embodiment, the corner device is provided with a flip horn correspondingly connected to the mold rotating cone.

[0020] In one embodiment, the position sensing sensor includes two sensing switches.

[0021] Specifically, an induction switch device is designed at the mobile flipping station, which mainly consists of two induction switches. When the mold is in place and moved to the flipping station, the induction switch sends a signal normally, the flipping trolley moves to grab the mold and move it to the next station, and the flipped mold falls to the next station.

[0022] In one embodiment, at least two portal-type support frames are provided below the two cross beams.

[0023] In one embodiment, the lifting device includes a double-chain chain hoist and a fixed slide rail device.

[0024] Specifically, the effects are as follows: First, the door frame structure of the turning station design of the utility model is much more stable than the existing technology. Secondly, the lifting device adopts a double-chain chain hoist and a fixed slide rail device, which is more powerful, safer and more reliable than the telescopic cylinder-driven boom device of the existing technology.

[0025] Secondly, the opening and closing cylinder extends, triggering the position sensor, so that the flip bell mouth and the mold rotating cone are aligned and the position sensor is triggered; the mold is moved to the next station by the flip trolley, and the mold is in place, effectively improving the efficiency of mold flipping.

[0026] Finally, the entire flipping process in this utility model is automatically controlled by the system, from mold removal to mold flipping and movement to the next station. Compared to the existing technology of mold flipping using a trolley, this truly achieves intelligent manufacturing. This technology significantly improves efficiency, utilizing advanced technologies such as a fixed beam, a flipping trolley, a flipping device, a lifting device, a hydraulic station, and an electronic control system to achieve improved mold flipping efficiency. This technology is also very simple to design, manufacture, operate, control, and use, making it suitable for widespread use.

[0027] The specific process of using a mold destacking and flipping tool is as follows:

[0028] S1. When the mold is transported from the curing kiln to the mold support by the mother-and-child car, the material presence sensor is triggered. The material presence information is transmitted back to the central control room, and the central control room sends a station start operation instruction to the station subsystem PLC;

[0029] S2. The workstation subsystem issues a command, and the electronic control system controls the lifting device to descend (or rise) to trigger the position sensor. The position of the angler corresponds to the mold.
