Technical Field

[0001] The utility model relates to the technical field of mobile lifting platforms, in particular to a multifunctional platform vehicle. Background Art

[0002] With the rapid development of modern industry, the application of lifting hydraulic platform vehicles is becoming more and more extensive, and the market demand is also increasing. It has become an indispensable and important equipment in the logistics industry. It not only improves logistics efficiency and meets various logistics needs, but also effectively improves the handling and lifting of materials, greatly improving the production efficiency of enterprises.

[0003] The existing utility model patent application number 202323283580.3 discloses a hydraulic lift platform vehicle, comprising a cart, the cart comprising a vehicle body and a push handle. A slot is provided on the upper surface of the vehicle body and extends through its lower surface. A vertically upward and retractable lifting module is disposed in the slot. A power module is disposed in the slot below the lifting module through a corresponding support seat, and the power module provides power for the extension and retraction of the lifting module. A mobile power supply is disposed on one side adjacent to the power module through a corresponding support seat. An electric control box for controlling the lifting of the lift platform vehicle is disposed on the push handle, and the power module is electrically connected to the electric control box. This utility model realizes automatic lifting, improves operating efficiency, lowers the center of gravity height of the lift platform vehicle, makes the center of gravity more stable, and enhances operational stability and safety. It also achieves versatility and aesthetics. It prevents operators from operating the lift platform vehicle under low voltage conditions, thus providing undervoltage protection.

[0004] However, the push handle of this patent cannot be folded, cannot detect the weight of the goods on the platform, and the lifting and lowering by the electric hydraulic cylinder is easily damaged, resulting in failure to lift or lower. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multifunctional platform vehicle with a simple structure, a weighing function, stable lifting and a handle that can be folded and stored, in view of the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a multifunctional platform vehicle, comprising a chassis and a push handle, casters are provided at the four corners below the chassis, and the characteristics are: a weighing platform is provided above the chassis which can be raised and lowered, a weighing sensor and a first slide rail arranged oppositely are provided in the weighing platform, a second slide rail arranged oppositely is provided in the chassis, a scissor group is provided between the first slide rail and the second slide rail on the same side, the scissor group comprises a first scissor arm rotatably provided in the chassis and a second scissor arm rotatably provided in the weighing platform, the first scissor arm is remote One end of the base frame slides in the second slide rail, and the first scissor arm slides in the first slide rail away from the weighing platform. The middle parts of the first scissor arm and the second scissor arm are hinged to each other, and the two second scissor arms slide on one end of the first slide rail and are connected to each other with a connecting rod. A screw rod is provided in the base frame in a vertical direction of the connecting rod. The screw rod is threadedly connected to the connecting rod and enables the first scissor arm to slide back and forth along the first slide rail and the second scissor arm to slide back and forth along the second slide rail to realize the lifting of the weighing platform. When the weighing platform is at the lowest point, the push handle can be folded toward the weighing platform to form a storage state.

[0007] With the above technical solution, after the lead screw rotates continuously, the position of the connecting rod on the lead screw also moves forward and backward along the length direction of the lead screw, and the two ends of the lead screw are respectively rotated and set on the base frame. When the weighing platform is at the lowest point, the lead screw is just blocked by the weighing platform, thereby making the platform vehicle more beautiful. The two ends of the connecting rod can also drive the second scissor arm to slide back and forth through sliders or pulleys. Since the second scissor arm and the middle part of the first scissor arm are hinged to each other, when the connecting rod is rotated by the lead screw and continuously slides toward the push handle, the first scissor arm is also driven by the second scissor arm to continuously slide toward the push handle in the first slide rail. At this time, the angle between the first scissor arm and the second scissor arm continues to shrink. The weighing platform continues to descend until it reaches the lowest point. At this time, the push handle can also be folded and stored and attached to the weighing platform. At this time, the storage space of the platform car is reduced, making it more convenient to store; when the connecting rod is rotated by the screw rod and continuously slides away from the push handle, the first scissor arm is also driven by the second scissor arm and continuously slides away from the push handle in the first slide rail. At this time, the angle between the first scissor arm and the second scissor arm continues to increase. At this time, the weighing platform continues to rise until it reaches the highest point. At the same time, the weighing platform also weighs the items placed on the weighing platform through the weighing sensor at its bottom, so that the platform car can not only be lifted and lowered, but also weighed, and can also be moved by casters.

[0008] A multifunctional platform vehicle can be further configured as follows: the first scissor arm is provided with a first pulley that slides back and forth along the first slide rail, the second scissor arm is provided with a second pulley that slides back and forth along the second slide rail, and the first slide rail or the second slide rail is provided with a limit block that abuts against the first pulley or the second pulley to form a limit when the weighing platform is lifted to a set height.

[0009] By adopting the above technical solution, the resistance of the pulley is smaller than that of the slider. The present application adopts the combination of the screw rod and the connecting rod to achieve lifting, so the pulley is more labor-saving. The position of the limit block can be set in the middle of the first slide rail or the second slide rail to prevent the weighing platform from being excessively lifted, resulting in the subsequent weighing platform being unable to stably support the heavy object. The limit block increases the stability of the platform vehicle of the present application, so that it can withstand heavier objects.

[0010] A multifunctional platform vehicle can be further configured as follows: a handle is fixedly provided at one end of the screw rod away from the push handle, and the forward or reverse rotation of the handle causes the second pulley to move along the second slide rail close to the push handle to lower the weighing platform or move away from the push handle to raise the weighing platform.

[0011] With the above technical solution, a handle is provided at the end of the screw rod away from the push handle so that the handle will not be affected when it is rotated. The handle can be a round handle or a grip handle type. The round handle type makes it more convenient to apply force, and the grip handle type allows the handle to be stored, thereby further reducing the storage volume. When the handle rotates forward, that is, clockwise, the thread of the screw rod drives the connected connecting rod to continuously slide toward the push handle, and the weighing platform descends at this time; and when the handle rotates reversely, that is, counterclockwise, the thread of the screw rod drives the connected connecting rod to continuously slide away from the push handle, and the weighing platform rises at this time.

[0012] A multifunctional platform vehicle can be further configured as follows: the second scissor arm is provided with a second pulley at one end for rotation and a clamping plate is provided on the top of the clamping plate. When the clamping plate rotates toward the push handle, the stepped clamping slot is connected to the push handle at one end of the base frame to prevent the weighing platform from falling. The clamping plate is provided with a limiting slot in the opposite direction of the stepped clamping slot, and the second scissor arm is provided with a hook at the limiting slot to prevent the clamping plate from rotating away from the push handle.

[0013] By adopting the above technical solution, the card board can also be set to a telescopic type so that it can adapt to different lengths. Its extension can adopt the telescopic structure of the handle of a folding umbrella or a telescopic desk and chair, and the limiting is achieved by the elastic arc-shaped protrusion. When the card board is rotated in the direction of the push handle (that is, counterclockwise), the stepped card slot is also on the lower side of the card board, and the base frame is also a hollow structure. When the weighing platform has a certain height, the stepped card slot can abut against the side of the base frame to prevent the weighing platform from falling suddenly, thereby increasing the stability of the platform vehicle of the present application. Since the card board needs to achieve a positioning effect when not in use, a hook is set in the limit slot to prevent the card board from reversing, and it can also achieve the positioning effect of the card board.

[0014] A multifunctional platform vehicle can be further configured as follows: a rotating seat is provided on the base frame, the push handle is rotatably arranged in the rotating seat, an arc-shaped rotating groove is provided on the rotating seat, a rotating rod passing through the arc-shaped rotating groove and the push handle is provided in the arc-shaped rotating groove, and the push handle moves in the arc-shaped rotating groove through the rotating rod to realize the limited rotation of the push handle.

[0015] By adopting the above technical solution, the push handle can be laid down and stood up through the arc-shaped rotating groove, and the rotation angle of the push handle can be controlled through the angle of the arc-shaped rotating groove. In addition, since the height of the entire platform vehicle is relatively low when the weighing platform is not raised, the push handle can be rotated and fitted on the top of the weighing platform to achieve the storage of the push handle. When the weighing platform is raised, the height of the weighing platform just presses the push handle toward one end of the weighing platform, thereby preventing the push handle from continuing to rotate, thereby achieving the positioning effect of the push handle.

[0016] A multifunctional platform vehicle can be further configured as follows: the two casters on the end of the base frame facing the push handle are universal wheels, the two casters on the end of the base frame away from the push handle are fixed wheels, and the universal wheels are provided with brake parts.

[0017] By adopting the above technical solution, the steering of the platform vehicle is achieved by setting the casters to have two fixed wheels at one end and two universal wheels at the other end. By setting brakes on the universal wheels, the platform vehicle can be stopped at the place of use, thereby realizing the functions of weighing and lifting, making the platform vehicle more stable.

[0018] A multifunctional platform vehicle can be further configured as follows: an instrument fixing plate is provided at one end of the push handle away from the rotating seat, a multifunctional instrument for displaying weighing weight is detachably provided on the instrument fixing plate, and the multifunctional instrument is electrically connected to the weighing sensor via a low-lying spring wire.

[0019] By adopting the above technical solution, the multi-function instrument is electrically connected to the weighing sensor through the base frame, and the multi-function instrument is detachably arranged on the instrument fixing plate. A number of protrusions can be set on the back of the multi-function instrument, and grooves can be set on the instrument fixing plate. In this way, the multi-function instrument can be separated from the platform vehicle during use, so that the weight can be observed in the hand, which makes observation more convenient. The low-pressure spring wire can be stretched and connected to the base frame during use, thereby increasing the range of movement of the multi-function instrument. The multi-function instrument can also be limited to the instrument fixing plate by the cooperation of the protrusions and the grooves, so that the multi-function instrument can be fixed on the instrument fixing plate, so that the multi-function instrument and the platform vehicle are integrated, thereby increasing the integrity of the platform vehicle.
