Description

Transfer trolley lifting and tilting device Technical Field

[0001] This invention relates to the field of lifting and tilting devices, and more particularly to a lifting and tilting device for a transfer trolley. Background Technology

[0002] In the production process, manufacturers often use transfer carts to move barrelled powders, granules, liquids, and other materials to designated workstations for unloading at the equipment inlet. After the transfer carts move the materials to the designated workstations, the lifting and unloading operations are usually performed manually. Each barrel typically weighs between 20kg and 50kg, resulting in high labor intensity, poor stability during unloading, and difficulty in effectively controlling the unloading speed. This can easily cause material to overflow from the equipment inlet and spill around the equipment, and the lack of control over the uncontrolled unloading speed can also lead to fluctuations in product quality. To address this, some companies have designed trolleys with lifting and tilting functions. However, these trolleys mostly use grippers to hold the end of the barrelled material and tilt it in a suspended state. This tilting method has limited support and holding power for the barrelled material, and is mainly suitable for barrelled materials weighing around 20kg (lighter weight). For barrelled materials weighing around 50kg (heavier weight), using this trolley is quite strenuous, and there is a risk of the grippers slipping off, structural components being damaged, and the barrelled material tilting or falling. Therefore, it is necessary to design a trolley lifting and tilting device that provides good material support, ensures a safe tilting process, and can stabilize the tilting speed.

[0014] The beneficial technical effects of this invention are:

[0015] (1) The present invention has a lifting mechanism on the trolley to lift or lower the internally installed tilting material conveying device. The tilting material conveying device is a tilting platform composed of a tilting support and a belt conveyor. The barrel material is placed on the tilting platform, and the internal belt conveyor conveys it to the front arc-shaped guide seat and locks it in place. After the lifting equipment inlet is lifted, the tilting motor on the lifting seat drives the entire tilting material conveying device to tilt forward, and the barrel material tilts forward to pour out the material. The device lifts and pours the barrel material on the tilting platform. Combined with the front arc-shaped guide seat, it can provide stable lifting and tilting support for the barrel material, and can cope with the tilting of large weight materials. It completely avoids the risk of large weight barrel material tilting and falling. It has high reliability and ensures the safe production of enterprises to a certain extent.

[0016] (2) The front end of the tilting material conveying device of the present invention is provided with an elastic support. When the material is tilted, the elastic support can provide elastic support at the front end, reduce the knob force on the motor output shaft, play a safety protection role, and also help ensure that the tilting material conveying device tilts and tilts the material at a uniform speed, thus avoiding large fluctuations in product quality.

[0017] (3) The present invention uses a conveyor belt mechanism in the flip-type material conveying device to transport the barrelled material in the trolley over a short distance, accurately and automatically transporting the barrelled material to the arc-shaped guide seat. This process does not require manual intervention, saving time and effort and has a high safety factor.

[0018] (4) The vertical sliding column of the locking mechanism of the present invention can slide and rotate vertically within the sliding support. When the vertical sliding column rotates inward, the arc-shaped locking plates at both ends rotate inward synchronously and fit against the upper and lower sides of the material bucket respectively. Then, the vertical sliding column is pressed down, and the two arc-shaped locking plates move downward. The claws at the upper end of the upper arc-shaped locking plate are locked at the upper port of the material bucket. At this time, the stop bar of the locking head can just move to the inner side of the lower end of the limiting plate. Then, the stop bar is rotated outward through the rotating sleeve of the locking head. The stop bar rotates to the lower end of the limiting plate and fits against its lower end face. The stop bar is locked on the limiting plate by screwing the butterfly nut. At this time, the vertical sliding column is fixed on the sliding support. The upper arc-shaped locking plate and the lower arc-shaped locking plate lock the material bucket in the arc-shaped guide seat. The locking mechanism has a locking effect on the material bucket. There is no risk of the material bucket slipping when pouring the material, which is conducive to ensuring safe production.

[0019] (5) The upper end of the vertical slide column of the locking mechanism of the present invention is fitted with a spring. After the material is poured out and the locking head is released from the lock on the vertical slide column, the vertical slide column can automatically return to its original position under the action of the spring force. The claw of the upper arc-shaped locking plate automatically separates from the upper port of the material bucket, releasing the lock on the material bucket. The operation is simple.

[0034] Example 1, see Figures 1-12 in the specification, a transfer trolley lifting and tilting device includes a lifting mechanism installed at the front end of the trolley and a tilting material conveying device installed in the lifting mechanism via a lifting seat;

[0035] The tilting material conveying device includes a tilting support, a belt conveyor mechanism, and a tilting motor. The main body of the tilting support consists of two symmetrically arranged angle iron-shaped side beams with a certain distance between them. A support shaft is horizontally fixed between the front ends of the two angle iron-shaped side beams, and the two angle iron-shaped side beams are fixedly connected into one unit by the support shaft. A support shaft can also be set at the rear end to improve the stability of the tilting support structure. The belt conveyor mechanism is installed between the two angle iron-shaped side beams. The conveyor belt of the belt conveyor mechanism is parallel to the upper surface of the tilting support. An arc-shaped guide is vertically provided in the middle of the front end of the tilting support. The guide seat has a flow guide port at the upper end, which guides the material in a directional manner, preventing the material from being thrown around at the equipment inlet. A locking mechanism is provided on each side of the arc-shaped guide seat. Two ear plates are symmetrically arranged in the middle of the upper surface of the lifting seat. One end of the support shaft in the tilting support is rotatably connected to one ear plate, and the tilting motor is fixedly connected to the outside of the other ear plate. Its output shaft is coaxially fixedly connected to the other end of the support shaft. The tilting motor drives the support shaft to rotate between the two ear plates, thereby driving the entire tilting support to tilt forward.

[0036] The transfer trolley is equipped with a lithium battery and control device, eliminating the need for an external power source, making it easy to operate and highly mobile.

[0037] The conveyor mechanism includes a square bracket made of profiles, a drive roller, support rollers, and a conveyor motor. The square bracket has symmetrical support plates on both sides of its bottom surface. The support plates and the angle iron-shaped side beams are fixedly connected as one unit by cross braces. The drive roller is laterally connected between one end of the two support plates. Support rollers are installed at both ends of the square bracket. The conveyor belt is fitted between the two support rollers and the drive roller. The conveyor motor is installed inside the drive roller and drives the drive roller to rotate via a belt. The drive roller drives the conveyor belt to rotate between the two drive rollers.

[0038] The front end of the lifting seat is equipped with two elastic support members. The upper ends of the two elastic support members are respectively hinged to the two sides of the front end of the square bracket. When the material is poured, the elastic support members can provide elastic support at the front end, reduce the knob force on the motor output shaft, play a safety protection role, and also help ensure that the tilting material conveyor device tilts and pours materials at a uniform speed.

[0039] The rear end of the lifting seat is equipped with two limiting supports. The upper end of the limiting supports is equipped with an arc-shaped groove. Rollers are provided on both sides of the rear end of the square bracket. The rollers correspond to the positions of the arc-shaped grooves below. When the barrelled material is placed on the tilting material conveyor and conveyed forward, the tilting material conveyor is in a horizontal state. The rollers on both sides can be matched and locked into the arc-shaped grooves of the limiting supports, providing support for the tilting material conveyor and ensuring the smooth conveying of the barrelled material.

[0040] Two guide rollers are symmetrically arranged on both sides above the drive roller. After the conveyor belt passes through the guide rollers, it wraps around the drive roller, ensuring the driving force of the drive roller on the conveyor belt. There are vertical elongated holes on the side support plates at both ends of the drive roller. The drive roller is installed between the two elongated holes, so that the support roller can move up and down to adjust the tension of the conveyor belt.

[0041] The lifting mechanism includes a portal frame fixedly connected to the front end of the trolley. A lead screw is rotatably installed in the vertical supports on both sides of the portal frame. The upper end of the lead screw is connected to a fixedly installed lead screw motor, and a lead screw nut is installed in the middle of the lead screw. The two ends of the lifting seat are connected to two lead screw nuts respectively. The synchronous rotation of the lead screws on both sides can drive the lifting seat to slide up and down through the lead screw nuts, thereby realizing the lifting operation of the tilting material conveying device.

[0042] The locking mechanism includes a sliding support, a vertical slide column, and an upper arc-shaped locking plate, all located on the upper side of the arc-shaped guide seat. The sliding support has a sliding hole in the middle of its horizontal plate and a limiting plate that is vertically downward at the outer end of the horizontal plate. The vertical slide column is slidably installed in the sliding hole. The inner end of the upper arc-shaped locking plate is provided with a bushing and is fixedly installed on the upper end of the vertical slide column through the bushing. Several claws are provided on the inner side of the upper edge of the upper arc-shaped locking plate, and a spring is fitted on the slide column between the horizontal plate and the bushing.

[0043] A locking head is fitted at the upper end of the vertical sliding column. The locking head includes a rotating sleeve and a stop bar that is radially connected to the middle of the outer side of the rotating sleeve. The rotating sleeve of the locking head is rotatably fitted onto the sliding column, and limit rings are provided at both ends of the sliding column. Therefore, the rotating sleeve can only rotate in the circumferential direction and cannot slide axially.

[0044] The bottom surface of the limiting plate has an arc-shaped limiting groove in the middle. The size of the arc-shaped limiting groove matches the size of the stop rod. After the stop rod enters the lower end surface of the limiting plate, it can slide into the arc-shaped limiting groove. The arc-shaped limiting groove is used to limit the stop rod and prevent it from rotating outward and slipping off the bottom surface of the limiting plate, thus ensuring the limiting effect on the vertical sliding column. The stop rod is threaded with a wing nut. Tightening the wing nut can lock the stop rod on the limiting plate, thereby fixing the vertical sliding column.

[0045] A handwheel is fixedly installed at the upper end of the vertical sliding column, allowing for easy rotation or sliding of the sliding rod. A lower arc-shaped locking plate is fixedly installed at the lower end of the vertical sliding column. The lower arc-shaped locking plate and the upper arc-shaped locking plate are arranged coaxially. The two arc-shaped locking plates can respectively fit against the upper and lower sides of the material bucket, ensuring balanced force distribution and good locking effect. The diameters of both the lower and upper arc-shaped locking plates are the same as the diameter of the material bucket, thus allowing for a good fit against the sides of the material bucket.

[0046] The locking mechanism is used as follows: When locking the material bucket, drive the vertical slide column inward by handwheel. The arc-shaped locking plates at both ends of the vertical slide column rotate inward simultaneously, respectively fitting against the upper and lower sides of the material bucket. Then, press the vertical slide column downward by handwheel. The two arc-shaped locking plates move downward, and the claw at the upper end of the upper arc-shaped locking plate locks into the upper port of the material bucket. At this time, the stop bar of the locking head can move to the inner side of the lower end of the limit plate. Then, rotate the stop bar outward by rotating the sleeve of the locking head. The stop bar rotates to the lower end of the limit plate and fits against its lower end face. Lock the stop bar on the limit plate by screwing the wing nut. At this time, the vertical slide bar is fixed on the sliding support, and the upper and lower arc-shaped locking plates lock the material bucket in the arc-shaped guide seat.

[0047] The method of using this invention is as follows:

[0048] ① Push the transfer trolley to the storage area for the barrelled materials and place the tipping material conveyor device.

[0049] The outer end connects to the storage platform for barrelled materials, automatically conveying the barrelled materials into the tilting material conveyor.

[0050] ② The conveyor mechanism drives the drummed materials forward within the tilting material conveyor device, directly...

[0051] The barrelled material enters the arc-shaped flow guide seat at the front end, and then the locking mechanism on both sides locks the barrelled material in the arc-shaped flow guide seat. The method of using the locking mechanism is described in detail above.

[0052] ③ Simultaneously start the two lead screw motors on both sides of the character-shaped frame, and the lead screws on both sides rotate synchronously.

[0053] The lifting seat is driven upward by the screw nut, and the tilting material conveyor is lifted upward synchronously with the barrelled material.

[0054] ④ After the equipment inlet is raised, the entire tilting conveyor is driven by the tilting motor on the lifting platform.

[0055] The device flips forward, causing the barrelled material to tilt forward and pour out. As the material is poured out, it passes through the arc-shaped guide port at the top of the arc-shaped guide seat, which provides directional guidance and prevents the material from scattering everywhere.
