Technical Field

[0001] This utility model relates to the field of mechanical devices, specifically providing a sand box tilting device. Background Technology

[0002] In the current sand box maintenance process, manual turning units are usually required to turn the sand box over. The workbench can only stop at a fixed angle or turn within a fixed range, which is inconvenient for employees of different heights. Turning is laborious and the work efficiency is low. In addition, the existing sand box turning units are usually single-sided turning devices or the sand box turning unit is set in an unreasonable position, resulting in a relatively unidirectional and large-amplitude shift of the center of gravity. When the sand box is turned to a certain angle that exceeds the stability limit of the workbench, the workbench is prone to tilting or even falling over, resulting in poor stability.

[0003] Therefore, it is necessary to propose a sand box flipping device to overcome the shortcomings of the prior art. Utility Model Content

[0004] The purpose of this utility model is to provide a sand box flipping device to solve the problems of poor stability and low working efficiency of the prior art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sand box flipping device includes: a flipping unit for carrying and flipping a sand box; a drive unit including a control box and a drive motor, wherein the control box is electrically connected to the drive motor and is used to supply power to the flipping unit, and the drive motor is used to drive a rotating shaft to rotate the flipping unit around an axis; and a bracket including a first bracket and a second bracket, wherein the first bracket and the second bracket are arranged adjacent to each other on the same base, a rotating shaft is provided in the middle of the first bracket, and the flipping unit is connected through the rotating shaft so that the flipping unit is suspended on the first bracket, and the second bracket is used to place and fix the control box.

[0007] Furthermore, the control box is used to house the battery, inverter, and frequency converter; the input terminal of the inverter is electrically connected to the output terminal of the battery, and is used to convert the DC power output by the battery into AC power; the input terminal of the frequency converter is electrically connected to the output terminal of the inverter, and is used to regulate the AC power and output the regulated AC power to the drive unit.

[0008] Furthermore, the drive unit also includes a reducer; the input shaft of the reducer is connected to the output shaft of the drive motor for receiving the driving force; the output shaft of the reducer is connected to the rotating shaft for outputting the reduced driving force to the rotating shaft.

[0009] Furthermore, the flipping unit is formed by a first support surface, a second support surface and a third support surface. The first support surface and the second support surface are respectively connected to the first bracket through a rotating shaft. The two symmetrical sides of the third support surface are respectively connected to the side of the first support surface and the side of the second support surface.

[0010] Furthermore, it also includes a control unit for receiving speed adjustment commands and continuously adjusting the output speed of the drive unit according to the speed adjustment commands.

[0011] Furthermore, the control unit is also configured to receive start / stop commands and steering adjustment commands; control the flipping unit to start or stop flipping according to the start / stop commands; and control the flipping unit to change the flipping direction according to the steering adjustment commands.

[0012] Furthermore, it also includes a speed sensor for detecting the real-time speed of the flipping unit; the control unit is also used to adjust the output speed of the drive unit according to the real-time speed.

[0013] Furthermore, it also includes a slide rail, which is fixedly installed below the flipping unit and extends in a preset direction; and a waste sand box, which is slidably installed on the slide rail to receive waste sand that falls during the flipping process.

[0015] Furthermore, it also includes a moving unit disposed below the base for moving the support.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By dividing the support into a first support and a second support set on the same base, the first support is connected to the flipping unit via a rotating shaft for flipping the sand box, and the drive motor is connected to the flipping unit via a rotating shaft. The second support holds and fixes the control box. This design allows the drive motor and control box to balance each other, preventing the support from tipping over due to the weight of the sand box during operation, thus improving stability. By setting a drive unit to rotate the flipping unit, automatic flipping is achieved, saving manpower. It also allows the sand box to stop rotating at any angle, overcoming the inconvenience to construction workers caused by stopping at a fixed angle.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0026] Please see Figure 1-3This utility model provides a sand box flipping device, including: a flipping unit 5 for carrying and flipping a sand box; a driving unit including a control box 4 and a drive motor 2, wherein the control box 4 is electrically connected to the drive motor 2 and is used to supply power to the flipping unit 5, and the drive motor 2 is used to drive a rotating shaft 8 to drive the flipping unit 5 to flip around an axis; and a bracket 1 including a first bracket 11 and a second bracket 12, wherein the first bracket 11 and the second bracket 12 are arranged adjacently on the same base 13, and a rotating shaft 8 is provided in the middle of the first bracket 11, through which the flipping unit 5 is connected so that the flipping unit 5 is suspended on the first bracket 11, and the second bracket 12 is used to place and fix the control box 4.

[0027] Specifically, such as Figure 1 and Figure 2 In the illustrated embodiment, the first support 11 has a door frame structure, with the flipping unit 5 located on top of the support 1 to facilitate automatic sliding of waste sand and to provide working space for construction personnel. The second support 12 has a cuboid frame structure, with the control box 4 placed inside to improve stability. Furthermore, the bottoms of the first support 11 and the second support 12 can be connected by welding or other means to increase the overall stability of the support 1.

[0028] It should be noted that through holes can be provided on the top of both sides of the first bracket 11, through which the rotating shaft 8 can be snapped in place. In addition, the axes of the rotating shafts 8 on both sides are collinear, and the two ends of the axes fall on the central axes of the first support surface 51 and the second support surface 52, respectively.

[0029] Specifically, in Figure 1 and Figure 2 In the embodiment shown, only one side of the rotating shaft 8 is connected to the drive motor 2, while the other side of the rotating shaft 8 is a driven rotating shaft, which is driven to rotate around the axis via the rotating shaft 8 connected to the drive motor 2.

[0030] Furthermore, such as Figure 2 As shown, a nut is installed at the connection point between the rotating unit 5 and the rotating shaft 8 on the side facing the sand box. It can be seen that the rotating shaft 8 and the rotating unit 5 are connected by bolts and nuts.

[0031] Specifically, such as Figure 2 As shown, the flipping unit 5 is formed by the first support surface 51, the second support surface 52 and the third support surface 53, forming a frame structure. The rotation axes on both sides are symmetrical, so that the weight of the sand box is evenly distributed on both sides, avoiding the tipping problem caused by the single-sided force of the flipping unit, and improving stability.

[0032] Furthermore, to improve the stability of the flipping unit 5, the inner sides of the first support surface 51, the second support surface 52 and the third support surface 53 can be provided with limiting structures for positioning the sand box. The limiting structures can be protrusions, grooves or clamping parts, etc., to limit the displacement of the sand box during the flipping process.

[0033] Specifically, according to Figure 1 and Figure 2 As shown in the embodiment, the components of the drive unit are located on the same side of the first bracket 11, which can provide counterweight and prevent the bracket 1 from tipping over when the heavy sand box is turned over. The control box 4 contains the battery, which is relatively heavy, and placing it on the base 13 can play a balancing role; the drive motor 2 is suspended on one side of the first bracket 11 through the rotating shaft 8, which not only balances the counterweight but also saves space.

[0034] In addition, the drive unit also includes a reducer 3. The output shaft of the reducer 3 is connected to the rotating shaft 8, and the drive motor 2 is connected to the reducer 3.

[0035] Since the rated speed of drive motor 2 is fixed and usually higher than the speed required by the flipping unit 5, if drive motor 2 directly drives the flipping unit 5, it will cause unstable operation of the equipment. Drive motor 2 will also experience overheating and shortened lifespan due to long-term inefficient operation. Reducer 3 can convert the high-speed output speed of drive motor 2 into a low-speed speed through a worm gear, reducing the occurrence of the above problems.

[0036] Furthermore, the drive motor 2 and the reducer 3 are connected by a coupling, one end of which is fixedly connected to the output shaft of the drive motor 2, and the other end is fixedly connected to the input shaft of the reducer 3.

[0037] Specifically, the two ends of the coupling can be fixed to the output shaft of the drive motor 2 and the input shaft of the reducer 3 by key connection or interference fit, and the output shaft of the drive motor 2 and the input shaft of the reducer 3 are kept coaxial by the coupling.

[0038] Furthermore, control box 4 is used to house the battery, inverter, frequency converter, and connecting cables. The battery is a 24V lithium battery, which outputs AC 220V power through the inverter. The frequency converter controls the speed of drive motor 2 to continuously change within a preset range by altering the frequency and voltage of the AC power. The output terminal of the frequency converter is electrically connected to the wiring terminal of drive motor 2.

[0039] Specifically, the drive motor 2 enables the sand box to rotate automatically, and the frequency converter allows the speed to be adjusted to a very low level at any time during construction, such as when inspecting the sand mold, so that operators can work at close range without having to frequently start and stop the equipment. It also overcomes the problem of inconvenience caused to construction personnel when the equipment can only be stopped at a fixed angle.

[0040] Furthermore, the sand box tilting device also includes a control unit for receiving user input commands for speed adjustment, start / stop, and steering adjustment, and for adjusting the working state of the drive unit according to the received commands.

[0041] Specifically, the control unit has the functions of receiving commands and control, and may also have a display function. The control unit may include a display screen for displaying the interface and receiving user input, and a microcontroller for controlling the operation of the sand box tilting device according to user input.

[0042] It should be noted that the drive motor 2 is connected to the flipping unit 5 via the rotating shaft 8. Therefore, adjusting the output speed of the drive unit is equivalent to adjusting the flipping speed of the flipping unit 5; sending start / stop signals or direction adjustment signals to the drive unit controls the drive unit to start, stop, or change the output direction, which in turn adjusts the flipping unit 5 to start, stop, or change the flipping direction.

[0043] like Figure 3 As shown, the control unit is signal-connected to the frequency converter and is used to coordinate and control the start, stop, direction and speed of the flip unit 5. Figure 3 The inverter is not shown in the embodiment shown. It can be understood that the battery in this embodiment has its own inverter, which supplies AC power to the frequency converter. The frequency converter supplies power to the drive motor 2 and adjusts the direction and speed of the drive motor 2, thereby driving the flipping unit 5 to flip through the reducer.

[0044] Furthermore, the sand box tilting device also includes a speed sensor for detecting the real-time speed of the tilting unit 5. If the control unit receives a speed adjustment command, it sends a speed adjustment signal to the frequency converter according to the target speed in the speed adjustment command and the real-time speed of the tilting unit 5, thereby adjusting the output speed of the drive unit so that the speed of the tilting unit 5 reaches the target speed.

[0045] Furthermore, the sand box tilting device also includes a waste sand box 7, which is used to collect waste sand scattered during the sand box tilting process and prevent dust from spreading. The waste sand box 7 becomes heavier when full, and the addition of a sliding rail eliminates the need for manual handling, improving work efficiency.

[0046] Furthermore, the slide rail may include two parallel tracks. Correspondingly, the bottom of the waste sand box 7 is provided with a slider adapted to the track, which is embedded in the track and slides along it. Limiting blocks may also be provided at both ends of the slide rail to limit the sliding range of the waste sand box 7 on the slide rail and prevent it from disengaging from the slide rail. In addition, the extending direction of the slide rail is parallel or perpendicular to the flipping axis of the flipping unit 5, so that the waste sand box 7 moves along the slide rail to or from directly below the sand box.

[0047] Specifically, a round hole is opened at the bottom of the waste sand box 7. When the waste sand in the waste sand box 7 reaches a certain amount, the round hole at the bottom can be used as a sand discharge channel. The waste sand can be discharged directly by gravity or by using a simple valve, without the need for manual handling of the waste sand box, thus reducing the downtime of operation.

[0048] Specifically, when controlling sand discharge through a valve, a valve can be installed at the round hole at the bottom of the waste sand box 7 to control the opening or closing of the round hole, thereby adjusting the discharge status of the waste sand.

[0049] Based on the above, the embodiment can be obtained by moving the waste sand box 7 directly under the flipping unit via the slide rail, and closing the bottom round hole of the waste sand box 7 via the valve. When the amount of waste sand in the waste sand box 7 reaches the preset amount, the waste sand box 7 is moved to the preset discharge point via the slide rail, and the bottom round hole of the waste sand box 7 is opened via the valve to discharge the sand.

[0050] Furthermore, such as Figure 2 As shown, the bottom of the waste sand box 7 is inclined. In this embodiment, the round hole can be opened at the lowest point of the bottom to guide the waste sand to gather.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, the moving unit 6 consists of at least two casters at the bottom of the support 1, which are used to move the support 1, improve the mobility of the support 1, and expand its working range.

[0052] Specifically, the moving unit 6 can also be equipped with a vibration damping structure to buffer the vibration generated during the movement of the support 1 or the operation of the flipping unit 5.

[0053] Furthermore, such as Figure 2 As shown, the sand box tilting device also includes a handle 9, which, together with the flexibility of the caster wheel, improves the ease of movement of the sand box tilting device, enabling it to serve multiple workstations and processes more flexibly.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
