Description

Technical Field

[0001] This invention relates to the field of glass fiber finished product placement cart technology, and more specifically to a glass fiber finished product placement cart. Background Technology

[0002] Glass fiber is an inorganic non-metallic fiber material made primarily from inorganic minerals such as quartz sand and limestone, which are melted at high temperatures and then drawn. It possesses advantages such as high strength, light weight, corrosion resistance, and good insulation properties, and is widely used in composite material manufacturing, building insulation, electronics, electrical engineering, and industrial products. In actual production and applications, glass fiber is often produced as continuous fibers into yarn, cloth, felt, or strip products, and is typically packaged and supplied in rolls for easy handling, storage, and use.

[0003] During the transportation, turnover, and temporary storage of finished glass fiber products, due to their long single roll length, uneven weight distribution, and relatively brittle fiber body, improper placement can easily lead to roll rolling, tipping, edge deformation due to pressure, or fiber surface wear. This not only affects the appearance quality and performance of the glass fiber but may also cause fiber breakage and scattering, increasing material loss.

[0004] Currently, the storage and transfer of finished fiberglass products in production workshops and construction sites generally rely on manual handling, supplemented by simple fixed supports or universal pallets. These traditional devices have obvious limitations: First, their structural form is singular, usually only supporting single-layer or small-scale stacking, resulting in low space utilization; second, they lack the ability to adapt to fiberglass rolls of different diameters and widths, and cannot flexibly adjust the load-bearing spacing; third, during the handling process, operators often have to forcibly pull the rolls in a specific direction or angle, which can easily lead to deformation, edge damage, or interlayer misalignment, resulting in low efficiency and affecting the quality of subsequent processing.

[0005] To address the aforementioned issues, there is an urgent need for a fiberglass finished product placement cart equipped with an adjustable receiving mechanism. This structure has both lateral and longitudinal adjustment capabilities, allowing for flexible adjustment of the support spacing and positioning position according to the actual size of the fiberglass roll. This enables integrated storage of products of various specifications while achieving multi-angle, unobstructed access and stability during transportation. Summary of the Invention

[0006] In response to the problems raised in the background art, the present invention provides a finished glass fiber placement cart to solve these problems, and the present invention will be further described below.

[0007] A finished fiberglass storage cart includes a cart with an incomplete frame structure, universal wheels with self-locking function installed at the bottom of the cart, and an adjustable receiving mechanism on the cart, which has the ability to adjust the horizontal width and vertical layer height to achieve compatible storage of products of various specifications. The adjustable frame mechanism on the cart can maintain structural stability during transportation and can be opened during loading and unloading operations to support multi-angle, unobstructed operation.

[0008] Preferably, the adjustable receiving mechanism includes four vertically parallel support frames, which are divided into two groups, left and right, and symmetrically slidably connected to the inner frame of the placement vehicle. Each support frame has a receiving frame 1 embedded in it, and the receiving frame 1 is provided with multiple independent placement units. A receiving frame 2 is embedded in it on the bottom plate of the placement vehicle.

[0009] Preferably, two symmetrically distributed adjusting screws are connected to the bottom of the rear side of the placement vehicle. The adjacent ends of the two adjusting screws are connected by a key to form an integral drive shaft. The threads of the two adjusting screws have opposite directions. A synchronous pulley is rotatably connected to the rear side of the placement vehicle. The synchronous pulley is connected to the adjusting screws by a belt. An adjusting handle is keyed to the side wall of the synchronous pulley. A movable plate is fixed to the outer side of the support frame on each set of support frames. The bottom of the movable plate is threaded to the adjusting screw on the corresponding side. The second support frame is threaded to the adjacent adjusting screw.

[0010] Preferably, a fixing block is fixedly connected to the side wall of the top support frame, and the fixing block is slidably connected to the frame of the placement vehicle. A fixing frame is fixedly connected to the side wall of the bottom support frame. A lifting device is installed on the top side wall of the placement vehicle. The output shaft of the lifting device is connected to chain rope one and chain rope two. Multiple rope pulleys are installed on the top of the placement vehicle. Chain rope one and chain rope two are arranged to pass around the rope pulleys and are respectively connected to the fixing blocks of the left and right top support frames and the outer frame of the support frame. Adjacent fixing blocks are connected by chain rope three.

[0011] Preferably, both sides of the first and second receiving frames are rotatably connected to protective frames, and each of the protective frames is equipped with a hydraulic shaping device.

[0012] Preferably, the adjustable frame mechanism includes a support rod that is transferred to the incomplete frame structure of the placement vehicle. The support rod has a pin hole at its top. The placement vehicle is equipped with two symmetrically distributed guide wheels. A chain rope is wound between the two guide wheels. A counterweight and a pin are fixed to the two ends of the chain rope, respectively. The pin is slidably connected to the incomplete frame structure of the placement vehicle. A spring is provided between the pin and the incomplete frame structure of the placement vehicle. The pin is located directly above the support rod, and the counterweight is located directly above the fixed block.

[0013] Beneficial effects: Compared with the existing technology, this device, through the adjustable receiving mechanism of chain rope one, chain rope two, and chain rope three, and the linkage of the adjusting screw, receiving frame one, and receiving frame two, realizes the flexible configuration of bearing width, layer height, and number of layers, meeting the storage, stacking, and efficient handling requirements of glass fiber finished products of different specifications.

[0014] The adjustable frame mechanism, through the linkage of counterweight, spring, and chain rope, enables automatic locking of the support rod and the placement vehicle, as well as unobstructed loading and unloading at multiple angles. This allows the support rod to be opened freely during loading, and the structure can be self-locked by the lifting and lowering of the fixed block and counterweight before transfer, ensuring transportation safety.

Detailed Implementation

[0019] Next, combine Figures 1-3 A specific embodiment of the present invention will be described in detail below.

[0020] refer to Figure 1 A fiberglass finished product placement vehicle includes a placement vehicle 1 with an incomplete frame structure, which serves as the main body for carrying and transporting fiberglass rolls. The bottom of the placement vehicle 1 is equipped with casters 4 with self-locking function, which facilitates flexible movement and precise positioning in the workshop or construction site. To accommodate fiberglass finished products of different lengths, diameters and stacking heights, the placement vehicle 1 is equipped with an adjustable receiving mechanism, which has the ability to adjust the horizontal width and vertical stacking height, so as to realize the compatible storage of products of multiple specifications. The placement vehicle 1 is equipped with an adjustable frame mechanism, which can maintain structural stability during transportation and open during loading and unloading operations to support multi-angle and unobstructed operation.

[0021] refer to Figure 1 and Figure 2 The adjustable receiving mechanism includes four vertically parallel support frames 11. The four support frames 11 are divided into two groups, left and right, and symmetrically slid on the inner frame of the placement vehicle 1. The support frames 11 slide along the vertical direction of the placement vehicle 1. Each support frame 11 is embedded with a receiving frame 12. The receiving frame 12 slides laterally along the top surface of the support frame 11 to expand the lateral bearing range. The receiving frame 12 is provided with multiple independent placement units. Each unit is used to accommodate one finished glass fiber product. The receiving frame 12 rises and falls synchronously with the support frame 11 to realize flexible adjustment of the vertical floor height.

[0022] In addition, a support frame 2 121 is embedded and slidably connected on the bottom plate of the placement vehicle 1. As the lowest bearing platform, it only has the function of lateral sliding and is used to further expand the bottom support width.

[0023] refer to Figure 2 To achieve lateral synchronous symmetrical adjustment of the first receiving frame 12 and the second receiving frame 121, two symmetrically distributed adjusting screws 19 are connected to the bottom rear side of the placement cart 1. The adjacent ends of the two adjusting screws 19 are connected by a key to form an integral drive shaft, and the threads of the two adjusting screws 19 are opposite. A synchronous wheel 112 is rotatably connected to the rear side of the placement cart 1. The synchronous wheel 112 is connected to the adjusting screws 19 by a belt 111. An adjusting handle is keyed to the side wall of the synchronous wheel 112 for manual operation.

[0024] refer to Figure 2 Each set of support frames 11 has a movable plate 110 fixedly connected to the outer side of the first support frame 12. The bottom of the movable plate 110 is threadedly connected to the adjusting screw 19 on the corresponding side. The second support frame 121 is threadedly connected to the adjacent adjusting screw 19. When the adjusting handle is rotated, the synchronous wheel 112 drives the two adjusting screws 19 to rotate synchronously via the belt 111. Since the screws rotate in opposite directions, the movable plates 110 on both sides and the second support frame 121 slide outward or inward synchronously, thereby precisely and symmetrically adjusting the overall lateral bearing width to adapt to glass fiber rolls of different lengths.

[0025] To support multi-layer stacking, a fixing block 16 is fixedly connected to the side wall of the top support frame 11, which slides with the frame of the placement vehicle 1. A fixing frame 17 is fixedly connected to the side wall of the bottom support frame 11. A lifting device 13 is installed on the top side wall of the placement vehicle 1. The output shaft of the lifting device 13 is connected to a first chain rope 14 and a second chain rope 15. Multiple rope pulleys 113 are installed on the top of the placement vehicle 1. The first chain rope 14 and the second chain rope 15 pass around the rope pulleys 113 in sequence according to the layout and are respectively connected to the fixing blocks 16 of the left and right top support frames 11 and the outer frame of the support frame 11, so as to realize the reasonable transmission of lifting force and multi-point synchronous force. Adjacent fixing blocks 16 are connected in series by a third chain rope 18.

[0026] In the initial state, all support frames 11 are in a low, retracted position, and chains 14, 25, and 318 are all in a slack state. After the crane 13 is started, it winds up chains 14 and 215, first lifting the top support frame 11. As the top fixing block 16 moves up, chain 318 is tightened, which in turn drives the fixing blocks 16 and support frames 11 of each layer below to rise step by step, realizing the synchronous and equidistant lifting of multiple support frames. The operator can adjust the support frame 11 to a suitable height according to the operation requirements (such as waist operating height, to avoid the operator frequently bending over and squatting), while leaving sufficient gaps between adjacent layers to accommodate thicker or isolated glass fiber finished products.

[0027] In summary, by using the adjustable receiving mechanism with chain rope 14, chain rope 2 15, and chain rope 3 18, and by linking the adjusting screw 19, receiving frame 12, and receiving frame 2 121, the flexible configuration of the bearing width, layer height, and number of layers is achieved, meeting the storage, stacking, and efficient retrieval requirements of glass fiber finished products of different specifications.

[0028] refer to Figure 1 To prevent fiberglass finished products from slipping laterally from the first support frame 12 and the second support frame 121 during transportation or storage due to vibration, tilting or inertia, protective frames 3 are rotatably connected to both sides of the first support frame 12 and the second support frame 121. Each of the protective frames 3 is equipped with a hydraulic shaping device, which has a damping locking function and can be fixed in position at any swing angle.

[0029] In actual operation, when it is necessary to limit and protect the fiberglass roll, the operator can manually unfold the protective frame 3 outward and flip it to a vertical or preset protective angle. At this time, the hydraulic shaping device will automatically lock, keeping the protective frame 3 stably in the working position, forming a lateral protective barrier, effectively limiting the lateral displacement of the finished fiberglass product. In loading, unloading, or when no protection is required, the locking state of the hydraulic shaping device can be released or the damping can be overcome by applying reverse force, and the protective frame 3 can be folded to the position where it fits against the side wall of the receiving frame to avoid interfering with the loading and unloading operations.

[0030] To overcome the drawbacks of traditional fixed placement carts, which require forcibly pulling the finished fiberglass product along a specific direction and are inconvenient to operate, while also ensuring flexible loading and unloading from multiple angles and structural stability during transportation, reference was made to... Figure 3The adjustable frame mechanism includes a support rod 2 that is connected to the incomplete frame structure of the placement vehicle 1. When the support rod 2 is in the closed state, it forms a complete rectangular closed frame together with the main frame of the placement vehicle 1, which significantly improves the structural rigidity of the whole vehicle during movement and transportation. The top of the support rod 2 has an unexposed pin hole for locking. The placement vehicle 1 is equipped with two symmetrically distributed guide wheels 23. A chain rope 22 is wound between the two guide wheels 23. The two ends of the chain rope 22 are respectively fixed with a counterweight 21 and a pin 24. The pin 24 is slidably connected to the incomplete frame structure of the placement vehicle 1. A spring 25 is provided between the pin 24 and the incomplete frame structure of the placement vehicle 1. The pin 24 is located directly above the support rod 2, and the counterweight 21 is located directly above the fixed block 16.

[0031] In the initial state, the chain rope 22 is taut, the spring 25 is compressed, the pin 24 is above the pin hole and not inserted for locking, and the support rod 2 is in a freely rotatable state. At this time, the operator can flip the support rod 2 outward to open it according to the work requirements, and easily load the finished glass fiber product into the receiving frame 12 or the receiving frame 2121 from any side or angle, eliminating the operational limitations caused by traditional unidirectional pull-out.

[0032] When loading is complete and overall transfer is required, the crane 13 is controlled to drive the support frame 11 to lift slightly upwards, causing the fixed block 16 to move upwards and push the upper counterweight block 21. The counterweight block 21 rises under force, the chain rope 22 is released, and under the action of the spring 25, it pushes the pin 24 to move down quickly and accurately embed into the pin hole at the top of the support rod 2, realizing automatic mechanical locking. At this time, the support rod 2 and the frame of the placement vehicle 1 are firmly combined into a complete rectangular structure, effectively suppressing frame deformation or roll material displacement caused by bumps, turns or sudden stops during transportation, ensuring overall stability and safety.

[0033] When the finished product needs to be picked up from multiple angles, the operation is reversed: control the lifting device 13 to move the support frame 11 down, the fixing block 16 will descend and disengage from the counterweight block 21. Under the action of the counterweight block 21's own weight, it pulls the chain rope 22 down, which in turn drives the pin 24 to slide up and out of the pin hole of the support rod 2, thus releasing the locking state. At this time, the support rod 2 can be freely flipped outward to open, and the operator can conveniently pick up the glass fiber finished product from any side, front or oblique angle.

[0034] The adjustable frame mechanism of this device achieves automatic locking of the support rod 2 and the placement cart 1 and unobstructed loading and unloading from multiple angles through the linkage mechanism of the counterweight 21, the spring 25 and the chain rope 22. The support rod 2 can be opened freely during loading. Before transfer, the structure can be self-locked by the lifting action of the fixing block 16 and the counterweight 21, ensuring transportation safety.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
