Description

Technical Field

[0001] This utility model relates to the technical field of refractory brick transportation equipment, specifically a refractory brick transfer trolley. Background Technology

[0002] Refractory bricks are a crucial high-temperature material, primarily used in industrial environments where they withstand extremely high temperatures, resist chemical erosion, and mechanical impact, ensuring stable equipment operation. The production process of refractory bricks mainly includes six stages: raw material processing, batching and mixing, molding, drying, firing, and post-processing.

[0003] After molding, refractory bricks typically need to be placed on transfer vehicles or storage racks before being transported to storage locations or directly loaded onto trucks. When it is necessary to transfer the refractory bricks to the calcining furnace for calcination, a transfer trolley is also required. However, existing transfer trolleys do not carry detachable transfer racks, and a significant amount of time is spent transferring the brick blanks during the drying and calcination processes. Therefore, improvements are needed.

[0004] Chinese Patent 202222194425.3 discloses "A Convenient Refractory Brick Transport Vehicle" (Publication No. CN217730503 U). The device includes a base plate, columns, and a top plate. Four columns are provided and are located at the four top corners of the base plate to form a support frame. The top plate is located on top of the columns, and wheels are provided at the bottom of the base plate. A multi-layer pull-out bearing structure is provided between the top plate and the base plate. Each layer of the pull-out bearing structure consists of two symmetrically arranged pull-out bearing frames. The pull-out bearing frames slide with the support frames through sliding rails, allowing the pull-out bearing frames to slide horizontally along the sliding rails. However, the device has some drawbacks: the device has low handling efficiency, and the pulling process itself consumes extra time; in order to prevent the bricks from shaking and falling during the pulling process, the operation speed needs to be slowed down, which further extends the preparation time for single-layer discharge. Moreover, the staff needs to carry the refractory bricks off the pull-out support frame one by one, and manual single-brick handling needs to be repeated many times, which increases the number of round trips for the staff and further reduces the handling efficiency of the staff. Utility Model Content

[0005] To address the problems of the prior art, this utility model provides a refractory brick transfer trolley with a support plate on its transfer frame. Workers can use the support plate to move multiple refractory bricks together without having to pick them up one by one, reducing the number of trips and thus improving the workers' handling efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a refractory brick transfer trolley, comprising a mobile bearing device, wherein multiple stacked loading units are arranged on the mobile bearing device, each loading unit comprising a loading plate and a support frame detachably connected to the upper surface of the loading plate, wherein multiple sets of support frames are arranged symmetrically, and a slot matching the support frame is provided on the lower surface of the loading plate.

[0007] With the above structural design, workers can use the loading platform to move multiple refractory bricks down together without having to grab them one by one, reducing the number of trips and thus improving the workers' handling efficiency.

[0008] Preferably, each of the support frames includes a vertical rod detachably connected to the loading plate and a gripping rod fixedly connected to the vertical rod. Two sets of vertical rods are provided and fixedly connected to the ends of the gripping rods respectively.

[0009] With the above structural design, when the load units are stacked, the support frame acts as a support for the load plate. When unloading refractory bricks, it is convenient for workers to hold the handles and use the load plate to move multiple refractory bricks down together.

[0010] Preferably, the surface of the grip bar is provided with anti-slip stripes.

[0011] The above structural design makes it easy for operators to hold the carrying unit when moving it, preventing slippage.

[0012] Preferably, the lower end of the vertical rod is fixedly connected to a fixing plate, one or more fixing bolts are passed through the fixing plate, and multiple threaded holes matching the fixing bolts are opened on the load plate.

[0013] The above structural design allows for a detachable connection between the vertical rod and the load plate through the engagement of fixing bolts and threaded holes, facilitating the installation, disassembly, and maintenance of the support frame. It also facilitates the logistics transportation of the device, as the support frame can be disassembled during transport, greatly reducing the packaging space required for the device and making it easier to transport.

[0014] Preferably, the threaded holes are arranged at equal intervals along the length of the carrier plate, and multiple slots are formed on the bottom surface of the carrier plate, with the slots aligned with the positions of the horizontally arranged threaded holes.

[0015] With the above structural design, when assembling loading units, the distance between the vertical rod and the edge of the loading plate can be adjusted according to the size of the refractory bricks, thereby making reasonable use of the space of the loading plate.

[0016] Preferably, the mobile support device includes a mobile plate, a mobile wheel fixedly connected to the bottom surface of the mobile plate, and a support plate fixedly connected to the upper surface of the mobile plate. The width of the support plate is less than or equal to the width of the slot. Multiple support plates are provided and arranged at equal intervals. A handrail is fixedly connected to the mobile plate.

[0017] With the above structural design, the movable wheels facilitate the movement of the entire transfer trolley, the handrails make it easy for operators to push the trolley, the support plates are used to support the lowest load unit, and their cooperation with the slots can further ensure the stability of the load unit on the moving load-bearing device; the spacing between the support plates is greater than the width of the forklift forks, which makes it easy for the forklift forks to pass through the support plates, and then lift and transport the stacked load units together.

[0018] Preferably, the carrier plate has multiple arrayed ventilation holes.

[0019] The above structural design allows for air circulation through the vent holes, preventing moisture problems caused by poor ventilation during transport of refractory bricks. It also reduces the weight of the load plate, making transport easier.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1) This device sets up multiple stacked loading units, and the slots on the lower surface of the loading plate of the loading unit match the support frame, so that the multiple loading units are stacked stably. At the same time, the support frame is symmetrically arranged, which can play a good role in limiting the refractory bricks and effectively prevent the refractory bricks from shaking, tilting or falling during transportation, thus improving the stability and safety of transportation.

[0022] 2) Convenient loading and unloading: The grip bar makes it easy for operators to move the loading unit, making the loading and unloading process more convenient and labor-saving. Workers can use the loading plate to move multiple refractory bricks down together without having to grab them one by one, reducing the number of trips and thus improving the handling efficiency of workers.

[0023] 3) Good practicality: The ventilation holes help keep the refractory bricks dry, and the moving wheels and handles of the mobile load-bearing device make the trolley easy to move. The overall structure is reasonably designed, highly practical, and can also be used with a forklift. Attached Figure Description

[0028] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: a refractory brick transfer trolley, including a mobile bearing device 1, on which multiple stacked loading units 2 are arranged. Each loading unit 2 includes a loading plate 21 and a support frame 22 detachably connected to the upper surface of the loading plate 21. Multiple sets of support frames 22 are arranged symmetrically. The lower surface of the loading plate 21 is provided with a slot 23 that matches the support frame 22. In order to engage with the support frame 22, the slot opening of the slot 23 faces downward. In order to prevent the support frame 22 from moving, both ends of the slot 23 are closed. The length of the slot 23 is the same as or slightly greater than the length of the support frame 22.

[0029] Please see Figure 1 , Figure 2 , Figure 3 Each support frame 22 includes a vertical rod 201 detachably connected to the carrying plate 21 and a gripping rod 202 fixedly connected to the vertical rod 201. Two sets of vertical rods 201 are provided and fixedly connected to the ends of the gripping rods 202 respectively. To prevent the support frame 22 from moving, the two ends of the slot 23 are closed. The length of the slot 23 is the same as or slightly longer than the length of the gripping rod 202. When stacking the carrying units, the slot 23 of the upper carrying unit engages with the gripping rod 202 of the lower carrying unit.

[0030] Please see Figure 1 , Figure 2 The grip bar 202 has anti-slip stripes on its surface, which can effectively increase the friction between the hand and the grip bar, making it easier for operators to hold the load unit when carrying it and preventing slippage.

[0031] Each loading platform 21 is equipped with two support frames 22, meaning that each loading platform 21 has two gripping rods 202. The symmetrical design of the two gripping rods 202 allows for single-person operation with both hands, and also supports two people to hold the two gripping rods 202 on each side for collaborative handling. When the total weight of the loading platform and bricks exceeds the carrying capacity of a single person, multiple people can work together by gripping the rods 202 to lift and move the load more smoothly, avoiding accidents caused by a single person struggling to carry the load (such as the loading platform tipping over or people getting injured), thus expanding the load application range of the device.

[0032] Please see Figure 1 , Figure 2The lower end of the vertical rod 201 is fixedly connected to a fixing plate 204. One or more fixing bolts 205 are inserted through the fixing plate 204, and multiple threaded holes 206 matching the fixing bolts 205 are formed on the carrying plate 21. Through the cooperation of the fixing bolts 205 and the threaded holes 206, the vertical rod 201 and the carrying plate 21 are detachably connected, which facilitates the installation, disassembly and maintenance of the support frame 22.

[0033] Please see Figure 1 , Figure 2 The threaded holes 206 are arranged at equal intervals along the length of the carrier plate 21. Multiple slots 23 are formed on the bottom surface of the carrier plate 21, and the positions of the slots 23 are aligned with the positions of the horizontally arranged threaded holes 206. This arrangement ensures that when multiple carrier units 2 are stacked, the slots 23 of the upper carrier unit 2 can precisely engage with the support frame 22 of the lower carrier unit 2, guaranteeing the stability of the stack. Since the dimensions of refractory bricks produced by different manufacturers may vary, the installation positions of the vertical rod 201 and the holding rod 202 may affect the arrangement of the refractory bricks when loading them onto the carrier plate, potentially making inefficient use of the carrier plate's area. After receiving this device, the manufacturer can freely choose the installation positions of the vertical rod 201 and the holding rod 202 according to the dimensions of the refractory bricks they produce, allowing for efficient use of the carrier plate's area. Furthermore, the vertical rod 201 and the holding rod 202 can restrain the refractory bricks, preventing them from moving due to swaying.

[0034] Please see Figure 3 The cross-section of the slot 23 is an inverted trapezoid, with the slot 23 being narrower at the top and wider at the bottom, which makes it easier for the gripping rod 202 to be inserted into the slot 23.

[0035] Please see Figure 4 The mobile carrying device 1 includes a movable plate 11, movable wheels (not shown in the accompanying drawings) fixedly connected to the bottom surface of the movable plate 11, and support plates 12 fixedly connected to the upper surface of the movable plate 11. The width of the support plates 12 is less than or equal to the width of the slot 23. Multiple support plates 12 are provided and arranged at equal intervals. Handrails 13 are fixedly connected to the movable plate 11. The spacing between the support plates 12 is greater than the width of the forklift forks, thus facilitating the forklift forks to pass through the support plates and lift and transport the stacked load units together.

[0036] The carrier plate 21 has multiple arrayed ventilation holes 4. The ventilation holes 4 facilitate air circulation and prevent the refractory bricks from becoming damp during transportation due to lack of air permeability. At the same time, it can also reduce the weight of the carrier plate 21, making transportation easier.

[0037] Different refractory bricks have different weights, and the load-bearing capacity of the support frame 22 is limited. Within the load-bearing limit of the support frame and under the condition of ensuring safety, the staff selects the number of stacked load units.

[0038] Working principle:

[0039] Assembly of mobile support device 1:

[0040] First, install the four casters on the four corners of the bottom surface of the moving plate 11 and secure them with bolts to ensure that the casters rotate freely and are firmly connected to the moving plate 11. Then, weld the support plates 12 to the upper surface of the moving plate 11 at equal intervals. The spacing between the support plates 12 should be greater than the width of the forklift forks. After welding, clean and rust-proof the weld seams.

[0041] The handrail 13 is welded to one side of the movable plate 11. After welding, the verticality and firmness of the handrail 13 are checked, and then rust prevention treatment is carried out.

[0042] Assembly of cargo unit 2:

[0043] First, determine the installation position of the support frame 22 on the load plate 21 based on the size and placement requirements of the refractory bricks. Then, place the fixing plate 204 of the support frame 22 in the corresponding position on the load plate 21, aligning the bolt holes on the fixing plate 204 with the threaded holes 206 on the load plate 21. Insert the fixing bolts 205, put on the washers, and tighten the nuts to fix the support frame 22 to the load plate 21. Install the other support frames 22 in the same way, ensuring that all support frames 22 are symmetrically arranged and firmly installed.

[0044] Loading:

[0045] Place the assembled loading unit 2 on a flat ground, ensuring that the loading plate 21 is stable; according to the size and quantity of the refractory bricks, arrange the refractory bricks neatly on the loading plate 21, so that the refractory bricks are located between the support frames 22, and use the support frames 22 to limit the refractory bricks and prevent them from shaking.

[0046] Stacked loading unit 2:

[0047] Two operators work together, each holding a handle 202 on either side of the support frame 22 of the load unit 2 to lift the load unit 2 carrying refractory bricks. They carefully move the load unit 2 above the mobile support device 1, aligning the slot 23 on the lower surface of the load plate 21 with the support plate 12 on the mobile support device 1, and slowly lower the load unit 2 so that the support plate 12 is engaged in the slot 23, completing the placement of the first load unit 2. If multiple load units 2 need to be stacked, the same method is used, aligning the slot 23 of the upper load unit 2 with the support frame 22 of the lower load unit 2, and stacking them to ensure that the stacking is stable.

[0048] transport:

[0049] The operator holds the handle 13 of the mobile support device 1 and pushes the trolley. During the pushing process, a constant speed should be maintained, and sudden stops or turns should be avoided to prevent refractory bricks from falling.

[0050] Unloading:

[0051] Push the trolley to the unloading point and secure it.

[0052] Two operators work together, holding the handle 202 of the uppermost load unit 2, lifting it and moving it away from the load unit 2 below or the moving support device 1, placing it on a flat ground, and then unloading the refractory bricks; unload the refractory bricks on the other load units 2 in the same way.
