Description

Technical Field

[0001] This invention relates to the field of multi-size sample placement, and more specifically, to a conveying device and method for placing two or more multi-size and multi-specification samples through operations such as gripping, lifting, flipping, and assembling. Background Technology

[0002] In daily life and production, there are samples that are inconvenient to handle manually or require specific placement. These include samples of multiple sizes, heavy weights, high temperatures, corrosive substances, or those with interlayers, which need to be assembled and then transported to a designated location. Therefore, based on the specific sample placement requirements in certain situations, in addition to placing the samples in the designated location, it is also necessary to improve the efficiency of placement and reduce unnecessary dangers. For example, before structural shear strength testing, for rock materials of different sizes and specifications with structural surfaces, it is necessary to precisely fit the structural surfaces of the upper and lower plate samples, or to place a weak interlayer at the structural surface before fitting. To prevent collision damage to the structural surfaces during transportation and to meet the on-site requirements of maintaining the moisture level of the structural surfaces or containing interlayers with special properties, the upper and lower plate samples need to be gripped, flipped, lifted, assembled, and placed in position before being directly transported to the designated location for testing or treatment. Currently, most placement and conveying devices only have the function of lifting and moving samples of a specific size or specification, and cannot achieve on-site placement and conveying of multiple samples under specific requirements.

[0003] Currently available positioning devices are insufficient for the positioning and transport of multiple multi-sized samples. For example, the mechanical structures proposed in applications 201920813477.X (a packaging box lifting and flipping mechanism) and 201721172311.1 (an electric meter box lifting and flipping mechanism) are only designed for specific products or boxes and cannot meet the needs of multi-sized sample installation. The multi-scale sample grasping, flipping, and transporting mechanism with a mold, as described in application 201420329237.X (application number 20201143071), achieves mechanized multi-scale sample grasping, flipping, and transport. The 1.4 continuously infinitely adjustable multi-scale specimen lifting and loading device provides a device for placing specimens of any two different lengths with the structural surface facing upwards onto a designated platform of the testing machine. The mechanized multi-scale specimen grabbing and conveying device with application number 201320295062.0 provides a mechanized multi-scale specimen grabbing and conveying device. Both of these devices place the upper or lower plate specimens one by one onto the testing machine for installation. This results in low work efficiency for long-distance transportation. In particular, the structural surface installed after transporting the specimens one by one may not have the unique on-site conditions such as moisture content and weak interlayers, thus affecting the test results.

[0004] In summary, the current positioning devices have the following problems:

[0005] 1. For samples of different sizes and specifications to be placed, it is necessary to select the appropriate model of placement device. The samples need to be placed manually and tied up, etc., which may pose a risk of injury if they are placed and moved manually.

[0006] 2. Existing methods make it difficult to fit two multi-sized samples together in a single placement device. Instead, samples are often transported to a designated location one by one before being placed. This is inefficient for long-distance sample transport. More importantly, transporting samples one by one can lead to problems such as bumps and performance loss for samples with special requirements on a particular test or processing surface. Summary of the Invention

[0007] To overcome the shortcomings of existing technologies, this invention provides a positioning and conveying device for two or more multi-sized samples through a grabbing, lifting, flipping, and bonding operation. It is used for bonding, positioning, sealing, and transporting two or more multi-sized and multi-specification samples on-site after special materials such as special surface installation interlayers are applied. It features high work efficiency, convenient operation, and maintaining the sample bonding surface in accordance with on-site conditions.

[0008] The technical solution adopted by this invention to solve its technical problem is:

The upper sprocket mounting shaft is mounted on the upper support frame via bearing seats, and two upper sprockets are mounted on the upper sprocket mounting shaft. The lower part of the support frame is mounted via bearing seats. Two lower sprocket mounting shafts are connected to the output shaft of the dual-output shaft motor located in the middle. Each lower sprocket mounting shaft has one lower sprocket installed. The upper and lower sprockets are driven by a chain. Vertical guide rails are installed on both sides of the mounting support frame. In front of the vertical guide rails is a movable frame, which is connected to the chain and driven by it to move up and down. Inside the movable frame are two parallel pulley mounting shafts, each with two pulleys. The pulleys move within the vertical guide rails. A mounting plate is fixed in the middle of the movable frame.

[0012] Furthermore, the gripping and flipping device includes a bearing seat, a left rotating shaft, a lead screw, a clamping handwheel, a sample mounting plate, a clamping plate, a right rotating shaft, and a flipping handwheel. The sample mounting plate with a "U"-shaped structure has a coaxial left rotating shaft and a right rotating shaft installed on both sides. The left rotating shaft and the right rotating shaft are respectively installed in the bearing seat, which is fixed below the mounting plate of the moving frame. The clamping plate passes through multiple grid-like square columns on the left side of the sample mounting plate and moves directionally along them. The lead screw is connected to the clamping plate to form a lead screw drive. A clamping handwheel is installed at one end of the lead screw, and a flipping handwheel is installed at one end of the right rotating shaft.

[0013] The lifting device includes a lifting cylinder, a lifting plate, a clamping cylinder, a clamping cylinder mounting base, a clamping plate, a clamping plate mounting platform, a transverse guide rail, clamping arms, and a lifting guide rail. The cylinder barrel of the lifting cylinder is fixed in the middle of the rear connecting plate of the transport frame. The end of the piston rod of the lifting cylinder is connected to the lower part of the lifting plate. The lifting plate is connected to the rear connecting plate through the lifting guide rail and can move up and down. The clamping plate mounting platform is fixed in the middle of the lifting plate. Two clamping plates are symmetrically installed on the clamping plate mounting platform through the transverse guide rail. A clamping cylinder mounting base is installed directly above each clamping plate. The cylinder barrel and piston rod of the clamping cylinder are respectively connected to the clamping cylinder mounting base. A clamping arm is fixed on each clamping plate.

[0014] A method for lifting, flipping, and positioning multi-sized samples, the method comprising the following steps:

[0015] The first step is to put all the mechanisms of the device into their initial positions: the two moving frames move to the front of the transport frame, the flipping device rises to the highest point, the grabbing and lifting device descends to the bottom, and the two clamping arms move to the maximum distance.

[0016] The second step is to clamp and lift the first sample;

[0017] The third step is to flip the first sample;

[0018] Fourth step: Clamp and lift the second sample;

[0019] Fifth step, align the two samples vertically and maintain a certain distance: adjust the height of the flipping device so that the first sample is above the second sample, move the moving frame to the back of the transport frame so that the first sample is exactly above the second sample, and adjust the position to make the two samples fit together.

[0020] Step 6: Adhere the two samples together;

[0021] Step 7: Transport the sample to the designated location: The flipping device releases the sample and adjusts its position by moving the frame so that the sample mounting plate of the flipping device is below and close to the second sample. Unlock the guide wheel, push the transport frame to place the sample above the designated location, move the flipping device to the initial position, lower the lifting device into place and release the sample, and then raise it to a certain height before moving the device away and resetting it.

[0022] Preferably, in the second step, the positioning and conveying device moves to the sample to be positioned, the position of the device is adjusted, the two clamping arms of the lifting device clamp the sample under the operation of the clamping cylinder, and then the lifting cylinder lifts the sample to the designated position. During the lifting process, the guide wheel can be self-locked to maintain stability.

[0023] In the third step, under the operation of the moving frame of the moving frame, the flipping device descends to below the sample, the moving frame moves to the rear side of the transport frame so that the sample mounting plate of the flipping device is directly below the sample, the position of the flipping device is finely adjusted so that the sample mounting plate is attached to the bottom of the sample, the two clamping arms release the sample, the flipping device descends to a certain position and clamps the sample by clamping handwheel, and flips the sample 180 degrees by flipping handwheel.

[0024] In the fourth step, the moving frame is moved back to the front of the transport frame, the lifting device is lowered back to the bottom and the two gripping arms are moved to the maximum distance. The operation steps of the second step are repeated, and the lifting device grabs the second sample and lifts it to a lower height.

[0025] In the sixth step, it is determined whether special materials such as interlayers need to be installed and bonded. If no special materials are needed, the two samples are bonded by adjusting their positions. If some interlayers or other materials need to be added above the second sample, the height of the bonded second sample is lowered or raised above the height of the first sample. The materials can be re-bonded after placement. After the materials are fully installed on both samples, the surface of the bonded area is sealed with tape or foam material.

[0026] The beneficial effects of this invention are mainly reflected in the following aspects: the positioning and conveying device utilizes the gripping and lifting mechanism of the flipping device 3 and the lifting device 4 to transport multiple samples; its significant functional feature is that the positioning device can simultaneously complete the on-site installation and positioning of two or more samples that need to be bonded, ensuring that the bonding process meets the required environmental conditions, especially for the special needs of materials such as interlayers. Through the coordination of the mechanism itself, it can ensure that the two samples are statically bonded for a long time, ensuring that the interlayers and other materials are more effectively bonded to the two samples, maintaining the on-site characteristics after sealing; it meets the need for one-time placement during long-distance transportation, preventing the impact of environmental conditions and accidental impacts on the bonding surface during transportation; it effectively prevents damage that may occur during manual handling and positioning during the entire positioning and transportation process; and because of the clamping device, the samples to be positioned can be of multiple sizes and specifications, making it widely applicable.

[0041] A method for grabbing, lifting, flipping, and conveying multi-sized samples to their designated positions, based on the above-mentioned mechanical structure and assembly, includes the following steps:

[0044] The third step is to flip the first sample: Under the operation of the moving frame 24 of the moving frame 2, the flipping device 3 descends to the bottom of the sample.
