Description

Technical Field

[0001] This utility model relates to the field of mechanical transportation equipment technology, specifically a filter paper transport trolley. Background Technology

[0002] In various laboratories, chemical production, and industries with high demand for filter paper, the transportation and handling of filter paper is a common and important part of the work. As a key filtration material, filter paper plays an indispensable role in operations such as liquid filtration and sample separation.

[0003] Previously, in these work scenarios, the transportation of filter paper mainly relied on manual handling or simple flatbed carts. Manual handling of filter paper is not only inefficient, but also leads to continuously rising labor costs as the amount of filter paper used increases. Furthermore, during manual handling, due to limited physical strength and attention, it is difficult to maintain the accuracy and stability of the handling movements for extended periods, easily causing the filter paper to fold or break during transport, affecting its subsequent use and thus interfering with the entire experimental or production process.

[0004] While simple flatbed trolleys alleviate some of the manpower burden, they also present several problems. Firstly, flatbed trolleys lack effective means of securing filter paper. During transport, the filter paper is easily displaced and scattered due to vehicle bumps and turns, requiring frequent stops for reassembly and potentially leading to contamination or damage, thus reducing work efficiency. Secondly, flatbed trolleys lack flexibility and operability in confined spaces or scenarios requiring precise positioning, failing to meet the demands of complex working environments.

[0005] To address the aforementioned issues, we developed a high-efficiency, stable, and easy-to-operate filter paper transport vehicle to overcome the numerous drawbacks of traditional transportation methods, improve the efficiency and quality of filter paper transportation, meet the diverse needs of different industries for filter paper transportation, and promote the development of related industries. Utility Model Content

[0006] The purpose of this utility model is to provide a filter paper transport trolley, which pushes the vertical pressure plate downward through the pressing component, and at the same time pushes the horizontal pressure plate to move laterally along the sliding rods on both sides of the side plate. The avoidance groove on the horizontal pressure plate can avoid interference between the two when the vertical pressure plate is pressed down, so as to realize the transport and fixation of filter paper.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A filter paper transport trolley includes a main frame comprising a base plate and two end side plates, which together form the basic support structure of the trolley, providing a foundation for the installation of subsequent components. Several sliding rods are fixedly mounted parallel to each other on both sides of the end side plates to guide the movement of a transverse pressure plate. The sliding rods slide through the transverse pressure plate, allowing the pressure plate to move laterally along the sliding rods. A pressing assembly is fixedly mounted on the top of the main frame, primarily used to press and secure the filter paper placed on the trolley, preventing it from shaking or shifting during transport. Rotating wheels are installed around the lower edge of the base plate of the main frame, enabling the trolley to move flexibly and facilitating the transport of filter paper between different locations.

[0009] The pressing assembly includes a fixed plate and a vertical pressure plate, both of which have rotating holes and rotating grooves on their sides. The fixed plate provides fixation and support, while the vertical pressure plate directly acts on the filter paper to achieve the pressing action. The fixed plate and the vertical pressure plate are connected by a centrally rotating cross link. This cross link connection is a scissor-type structure, allowing the vertical pressure plate to move up and down by rotating the cross link. The rotating holes and rotating grooves on the sides of the fixed plate and vertical pressure plate, respectively, provide rotatable and sliding connections. The rotatable connection allows the cross link to rotate flexibly around the rotating hole, while the sliding connection allows the cross link to slide within the rotating groove, thus ensuring the smooth operation of the entire pressing assembly.

[0010] A second hydraulic cylinder is connected between the rotating rod in the middle of the cross linkage and one of its forked arms. This second hydraulic cylinder is a key component providing power. Both ends of the second hydraulic cylinder are rotatably connected, ensuring that the second hydraulic cylinder can flexibly drive the cross linkage during extension and retraction. When the extension rod of the second hydraulic cylinder extends, it pushes the cross linkage to rotate, causing the vertical pressure plate to move downwards, thus pressing the filter paper. When the extension rod of the second hydraulic cylinder retracts, the vertical pressure plate lifts upwards, releasing the filter paper.

[0011] The side plate of the main frame has a slot to provide space for the installation and movement of subsequent components. An L-shaped baffle extends outward from the slot from the bottom plate of the main frame. This L-shaped baffle serves to fix and support the first hydraulic cylinder. The first hydraulic cylinder is fixedly mounted on the L-shaped baffle, and the top end of the first hydraulic cylinder's telescopic rod is fixedly connected to the transverse pressure plate. The first hydraulic cylinder is mainly used to control the lateral movement of the transverse pressure plate. When the first hydraulic cylinder's telescopic rod extends, it pushes the transverse pressure plate to one side along the sliding rod; when the first hydraulic cylinder's telescopic rod retracts, the transverse pressure plate moves in the opposite direction.

[0012] An clearance groove is provided on the upper side of the horizontal pressure plate, and the width of the clearance groove is the same as the width of the vertical pressure plate. The function of the clearance groove is to ensure that when the vertical pressure plate is pressed down, it falls exactly into the clearance groove, avoiding interference between the vertical pressure plate and the horizontal pressure plate, and ensuring the smooth operation of the entire pressing action.

[0013] When the filter paper transport trolley is in operation, the operator first pushes the trolley to the filter paper placement area using the handle, and then moves it into position using the rotating wheels at the bottom of the main frame. After placing the filter paper on the trolley, the second hydraulic cylinder is activated. Since its two ends are rotatably connected between the rotating rod in the middle of the cross linkage and one of its forks, when the extension rod of the second hydraulic cylinder extends, it pushes the cross linkage to rotate. Because the cross linkage is rotatably connected to the fixed plate and the two sides of the vertical pressure plate through rotating holes and sliding connections through rotating grooves, the vertical pressure plate moves downward, pressing the filter paper firmly. To loosen the filter paper, the extension rod of the second hydraulic cylinder retracts, and the vertical pressure plate rises. When it is necessary to adjust the lateral position of the filter paper on the trolley, the first hydraulic cylinder is activated. Its extension rod connects to the lateral pressure plate, and the extension rod extends, pushing the lateral pressure plate laterally along the sliding rods on both sides of the side plate. The clearance groove on the lateral pressure plate prevents interference between the two when the vertical pressure plate is pressed down, ensuring a smooth operation and achieving the transportation and fixation of the filter paper.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In terms of operation, the trolley is equipped with a handle and rotating wheels with high-precision bearings, making it easy to push, flexible to turn, and smooth to move. It can quickly and accurately reach the filter paper placement position, saving manpower and time, and providing more precise positioning.

[0016] When fixing the filter paper, the second hydraulic cylinder, the cross linkage, and the vertical pressure plate work together. The hydraulic cylinder has strong power and stable output, which can quickly push the cross linkage and drive the vertical pressure plate to press the filter paper. This solves the problems of the filter paper not being firmly fixed and being easily moved during transportation in the existing technology, ensuring the integrity of the filter paper and making it suitable for work with high requirements for flatness and positional accuracy.

[0017] When adjusting the lateral position of the filter paper, the first hydraulic cylinder connects to the lateral pressure plate. The telescopic rod precisely controls the movement of the lateral pressure plate. The clearance groove on the lateral pressure plate matches the width of the vertical pressure plate, preventing interference during downward pressure. This optimizes the operation process, reduces the risk of malfunction, and improves work efficiency. It enhances the stability and reliability of filter paper transportation, reduces the tedium and error rate of manual operation, and ensures the smooth progress of related work.

[0021] The technical solutions of the present invention will now be described in detail with reference to the accompanying drawings of the embodiments.

[0022] like Figure 1-2 As shown, a filter paper transport trolley includes a main frame 1. The main frame 1 includes a bottom plate and two end side plates. Several sliding rods 11 are fixedly installed parallel to each other on both sides of the two end side plates. A transverse pressure plate 2 slides through the sliding rods 11. A pressing component 3 is fixedly installed on the top of the main frame 1. Rotating wheels 4 are installed around the lower end of the bottom plate of the main frame 1.

[0023] The pressing assembly 3 includes a fixed plate 31 and a vertical pressure plate 32. Both sides of the fixed plate 31 and the vertical pressure plate 32 are provided with rotating holes and rotating grooves. The fixed plate 31 and the vertical pressure plate 32 are connected by a cross link 33 that rotates in the middle. The ends of the cross link 33 are rotatably connected to the rotating holes and rotating grooves on both sides of the fixed plate 31 and the vertical pressure plate 32, respectively.

[0024] A second hydraulic cylinder 34 is connected between the rotating rod in the middle of the cross link 32 and one of its forks. Both ends of the second hydraulic cylinder 34 are rotatably connected.

[0025] The side plate of the main frame 1 has a slot, and the bottom plate of the main frame 1 extends outward from the slot to form an L-shaped baffle. A first hydraulic cylinder 12 is fixedly installed on the L-shaped baffle, and the top end of the telescopic rod of the first hydraulic cylinder 12 is fixedly connected to the transverse pressure plate 2.

[0026] An avoidance groove is provided on the upper side of the horizontal pressure plate 2, and the width of the avoidance groove is the same as the width of the vertical pressure plate 32.

[0027] A handle 5 is fixedly installed on one side plate of the main frame 1.

[0028] Its specific implementation method is as follows:

[0029] When using the filter paper transport trolley, first check if the rotating wheel 4 rotates freely, if the first hydraulic cylinder 12 and the second hydraulic cylinder 34 leak, and if all connections are secure and reliable. After ensuring everything is in order, push the trolley to the filter paper placement area, ensuring there is sufficient operating space around it. Place the filter paper near the center of the bottom plate of the main frame 1. If the placement is off, activate the first hydraulic cylinder 12 on the L-shaped baffle on one side of the main frame 1. Its telescopic rod will extend and retract, pushing the connected transverse pressure plate 2 to move laterally along the sliding rod 11 to adjust it to the ideal transverse position. Next, activate the second hydraulic cylinder 34 in the pressing assembly 3. Its telescopic rod will extend and push the cross connecting rod 33 to rotate, causing the vertical pressure plate 32 to press down and tighten the filter paper. The clearance groove on the transverse pressure plate 2 can prevent interference with the vertical pressure plate 32 during pressing. After the filter paper is tightened, the operator holds the handle 5 on one side plate of the main frame 1 and uses the rotating wheel 4 to push the trolley to the destination. During transportation, be careful to avoid bumps and rapid turns. Upon arrival, first activate the second hydraulic cylinder 34 to lift the vertical pressure plate 32. If the lateral position needs to be adjusted for unloading, activate the first hydraulic cylinder 12 again to adjust the filter paper into place and remove it. Finally, push the trolley to the storage area, check the parts for being back in place, and clean up any impurities to prepare for the next use.
