Description

Technical Field

[0001] This utility model relates to the technical field of transport vehicle connecting plates, specifically a transport vehicle connecting plate. Background Technology

[0002] As an indispensable loading and unloading equipment in the warehousing and logistics field, the core function of the pallet truck is to realize the short-distance handling, lifting and stacking of goods. The connecting plate, as the core force transmission and connection component of the pallet truck, directly determines the load-bearing capacity, structural stability, service life and operational safety of the equipment.

[0003] When a robot performs a loading operation, the moment its robotic arm grabs a item and places it on the transport vehicle platform, a significant impact force and a continuous thrust are generated. This dynamic external force is transmitted through the item to the transport vehicle itself, easily overcoming the static friction of its braking system, causing the transport vehicle to slightly "backtrack." Similarly, when an operator forcefully pushes a heavy object onto the transport vehicle platform, a similar effect occurs. This can lead to inaccurate placement of goods, affecting subsequent stacking stability and transportation safety. More seriously, loading during movement can easily cause goods to slip off the transport vehicle due to sudden changes in the center of gravity. Utility Model Content

[0004] The purpose of this utility model is to provide a connecting plate for a transport vehicle, which is connected to the equipment by means of an adjusting plate and a connecting arm, and is fixed by the action of a first clamping member to prevent the transport vehicle from shifting when loading goods.

[0005] To address the existing technical problems, this utility model provides a connecting plate for a transport vehicle, which is applied to the transport vehicle body. It includes a connecting plate body that can be detachably installed on the top of the transport vehicle body. An adjusting plate is rotatably installed on one side of the connecting plate body, and the adjusting plate can rotate to be flush with the connecting plate body. A symmetrical connecting arm is fixed on one side of the adjusting plate, and a first clamping member that can move back and forth is also provided on the connecting arm.

[0006] Preferably, a first screw is rotatably connected to the connecting arm via a thread, and one end of the first screw is connected to a first clamping member, while the other end of the first screw is connected to a first handle.

[0007] Preferably, slots are provided at the four corners of the top of the transport vehicle body, and plugs that can be inserted into the slots are provided at the bottom of the connecting plate body.

[0008] Preferably, a support block is welded to the bottom of the connecting plate body, and a second screw is rotatably connected to the support block by a thread. One end of the second screw is connected to a second clamping member that can contact the side of the transport vehicle body, and the other end of the second screw is connected to a second handle.

[0009] Preferably, the top of the connecting plate body is provided with crisscrossing grooves.

[0010] Preferably, a support platform is placed on the top of the connecting plate body, and a number of protrusions are distributed on the bottom of the support platform, and through grooves are opened on the protrusions.

[0011] Preferably, a fixing component is provided between the connecting plate body and the support platform to fix the support platform to the top of the connecting plate body.

[0012] Preferably, the fixing component includes a slider that can be slidably disposed in a groove, and a third screw is rotatably disposed on the slider. The third screw can be engaged in a through groove. The fixing component also includes a pressure plate sleeved on the third screw, and the pressure plate presses on the top of the protrusion. A fixing nut is also threaded onto the third screw.

[0013] The advantages of this utility model compared to the prior art are:

[0014] The core improvement of this application lies in the addition of a connecting plate body. This connecting plate body has an adjusting plate connected to one side via a rotating joint. This structure allows the transport vehicle body to flexibly adapt to external conveying equipment during loading and unloading operations. The specific workflow is as follows: When the transport vehicle body needs to transfer goods to the conveying system, the operator drives it close to the conveying equipment; then, by manually rotating the adjusting plate, it rotates around the hinge point on the connecting plate body until the end of the adjusting plate aligns with the outer frame of the conveying equipment. To achieve reliable relative fixation, this application integrates a clamping mechanism on the connecting plate body. This mechanism includes a first screw, a first clamping component, and a first handle. During operation, by turning the first handle, the first screw is driven to produce axial displacement, which in turn moves the first clamping component, firmly clamping it onto the outer frame of the conveying equipment. This active clamping mechanism effectively restrains the transport vehicle body from accidental movement caused by force during loading and unloading, significantly improving operational stability and safety, especially suitable for working conditions with impact or vibration. Furthermore, to enhance the adaptability to carrying diverse goods, this application specifically designs a detachable support platform. Operators can flexibly select and replace support platforms of different specifications or shapes based on the specific shape, size, or center of gravity distribution of the goods to be transported. For example, for cylindrical, irregularly shaped, or specially protected goods, support platforms with corresponding contours or cushioning materials can be selected to optimize stress distribution and prevent slippage or damage during transport. It is worth mentioning that the modular design concept of this application extends further to the connection method between the transport vehicle body and the connecting plate body. Both are connected using a detachable structure, such as quick-release devices like pins, bolt sets, or clips. This design allows users to easily replace the connecting plate body with one having a larger surface area or a different structural form according to actual operational needs. When handling large batches or goods of special dimensions, replacing the connecting plate body with one having a larger area can expand the docking range and improve loading and unloading efficiency. In summary, this application, through the aforementioned multiple adjustable and detachable structural designs, significantly improves the functionality, adaptability, and overall efficiency of the handling equipment.

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-5 As shown, this utility model provides a connecting plate for a transport vehicle, applied to the transport vehicle body 1. It includes a connecting plate body 2 detachably mounted on the top of the transport vehicle body 1. An adjusting plate 22 is rotatably mounted on one side of the connecting plate body 2, and the adjusting plate 22 can rotate to be flush with the connecting plate body 2. Symmetrical connecting arms 221 are fixed to one side of the adjusting plate 22, and the connecting arms 221 are also provided with a first clamping member 23 capable of moving back and forth. A first screw 231 is rotatably connected to the connecting arm 221 via a thread, and one end of the first screw 231 is connected to the first clamping member 23, while the other end of the first screw 231 is connected to a first handle 232.

[0023] The operator drives the transport vehicle body 1 close to the target conveyor. Then, depending on the position of the conveyor, the operator manually rotates the adjusting plate 22, unfolding it from its retracted state with the connecting plate body 2 until its free end securely rests against or approaches the outer frame of the conveyor. After the adjusting plate 22 is in place, the operator turns the first handle 232. The first handle 232 drives the first screw 231 to rotate. Since the first screw 231 is threadedly connected to the connecting arm 221, the rotational motion of the first screw 231 is converted into a linear forward motion of the first clamping member 23 towards the outer frame of the conveyor. Finally, the first clamping member 23 is firmly clamped onto the frame. This effectively provides a temporary rigid connection between the transport vehicle and the fixed conveyor, preventing accidental movement or shaking of the transport vehicle due to factors such as cargo impact during loading and unloading, greatly improving the safety and stability of the operation. After clamping, the goods can be transferred manually or automatically. After loading and unloading is completed, the first handle 232 is turned in the opposite direction to retract the first clamping member 23 and release the clamp.

[0024] The four corners of the top of the transport vehicle body 1 are provided with slots 11, and the bottom of the connecting plate body 2 is provided with plugs 24 that can be inserted into the slots 11.

[0025] When it is necessary to install the connecting plate body 2, the operator lifts the connecting plate body 2 so that the four plugs 24 at the bottom are aligned with the four slots 11 at the top of the transport vehicle body 1. Then it is lowered so that the plugs 24 are fully inserted into the slots 11. This achieves quick installation of the connecting plate body 2.

[0026] The bottom of the connecting plate body 2 is also welded with a support block 25. The support block 25 is connected to a second screw 26 by a threaded connection. One end of the second screw 26 is connected to a second clamping member 261 that can contact the side of the transport vehicle body 1, and the other end of the second screw 26 is connected to a second handle 262.

[0027] After the insert 24 is in place, the operator begins to turn the second handle 262. The second handle 262 drives the second screw 26 to rotate. Since the second screw 26 is threadedly connected to the support block 25, the rotational motion is converted into linear motion of the second clamping member 261 toward the side of the transport vehicle body 1. Finally, the second clamping member 261 presses tightly against or clamps against the side wall of the transport vehicle body 1 with considerable lateral force, forming an extremely stable connection.

[0028] The top of the connecting plate body 2 is provided with crisscrossing sliding grooves 21. A support platform 3 is also placed on the top of the connecting plate body 2, and several protrusions 31 are distributed on the bottom of the support platform 3, with through grooves formed on the protrusions 31. A fixing component 4 is provided between the connecting plate body 2 and the support platform 3 to fix the support platform 3 to the top of the connecting plate body 2. The fixing component 4 includes a slider 41 that can be slidably disposed in the sliding grooves 21, and a third screw 43 is rotatably disposed on the slider 41. The third screw 43 can be locked in the through grooves. The fixing component 4 also includes a pressure plate 42 sleeved on the third screw 43, and the pressure plate 42 presses against the top of the protrusions 31. A fixing nut 44 is also threaded onto the third screw 43.

[0029] Place the selected support platform 3 on the top surface of the connecting plate body 2. Based on the position of the bottom protrusion 31 of the support platform 3, slide the slider 41 in the corresponding groove 21 grid until it is approximately below the through groove of the protrusion 31. Allow the shaft of the third screw 43 to pass through the through groove of the protrusion 31. At this point, the inner wall of the through groove engages with the third screw 43, restricting the horizontal movement of the support platform 3 and achieving initial positioning and connection. Place the pressure plate 42 onto the third screw 43, screw on the fixing nut 44, and tighten it using a tool such as a wrench. As the fixing nut 44 is screwed in, it presses downwards against the pressure plate 42, which then evenly transmits the large clamping force to the protrusion 31. This achieves the fixation of the support platform 3.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
