Abstract
Description
Technical Field
[0001] This utility model belongs to the field of logistics equipment technology, and relates to a turnover rack, specifically, a rack suitable for storing and turnover excavator booms. Background Technology
[0002] The boom is the core component of a hydraulic excavator, responsible for power transmission and load-bearing. The boom achieves lifting and lowering movements through a hydraulic system, supporting the excavator's stick and bucket to complete digging, unloading, and other actions.
[0003] Different models of hydraulic excavators have different boom sizes. When transporting the boom, custom-made racks are needed for each boom size, resulting in a large variety of racks and making management inconvenient. When production fluctuates, because the racks are not interchangeable, some racks need to be replenished, while others become surplus, causing significant waste.
[0004] To address the aforementioned issues, Chinese utility model patent CN204701952U discloses a boom turnover bracket, comprising a pallet, a forklift slot at the bottom of the pallet, and mounting plates at both ends of the upper part of the pallet. Contact seats that can swing left and right are hinged to the mounting plates, and limiting baffles are provided on both sides of the contact seats, fixed to the mounting plates to limit the maximum swing angle of the contact seats. When turnovering the boom, the curved lower cover plate of the boom is placed on the two contact seats, and the angle of the two contact seats is adjusted according to the curvature of the lower cover plate to obtain the maximum contact area.
[0005] The aforementioned bracket, which adjusts the angle of its two contact seats to accommodate booms of different sizes, aims to increase the contact area and thus make the boom more stable during rotation. However, this method is clearly unreliable. Excavator booms are large and heavy; without a reliable securing method, they are prone to accidental falling and damage or injury during rotation. Therefore, using the aforementioned bracket to rotate the boom poses a safety hazard and is not an ideal rotation device. Summary of the Invention
[0006] This utility model addresses at least one of the aforementioned technical problems in the prior art by proposing a boom rack that can not only accommodate booms of different sizes but also ensure the reliability of the boom's fixation on the rack.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0008] A boom rack for storing booms on construction machinery, the boom having a first end and a second end positioned opposite each other along its length; the boom rack includes:
[0009] The base, which is longer than the boom, has a head and a tail that are opposite each other in the length direction, and a slide rail is provided at the tail.
[0010] An adjustable mounting assembly is slidably mounted on the slide rail for fixing the first end of the boom;
[0011] A fixed mounting assembly is installed at the head of the base for securing the second end of the boom.
[0012] In some embodiments of this application, the adjustable mounting assembly may include a shaft for mounting at the first end of the boom, a bearing for supporting the shaft, a locking mechanism for locking the shaft in the bearing, and a slider; the locking mechanism is mounted on the bearing, and the slider is mounted on the bottom of the bearing and slidably fitted with the slide rail, so that the adjustable mounting assembly can slide along the slide rail, thereby changing the distance between the adjustable mounting assembly and the fixed mounting assembly.
[0013] In some embodiments of this application, the slide rail can be designed as a long strip and arranged along the length direction of the base; the slider can be designed as a cylinder and configured so that the cross-sectional shape of the slider matches the cross-sectional shape of the slide rail, and the slider is fitted onto the outside of the slide rail to improve the reliability of the adjustable mounting assembly on the slide rail and the smoothness of the sliding process.
[0014] In some embodiments of this application, to ensure the boom is more securely supported on the rack, two slide rails can be arranged parallel and spaced apart along the width of the base. The distance between the two slide rails is greater than the width of the first end of the boom, thus positioning the first end of the boom between the two slide rails. Two sliders are provided in the adjustable mounting assembly, each slidably mounted on one of the two slide rails. A bearing seat is mounted on each slider, and a locking mechanism is installed on each bearing seat. After the shaft passes through the two shaft holes at the first end of the boom, both ends of the shaft can be supported in the two bearing seats respectively. The two locking mechanisms lock the two ends of the shaft in the two bearing seats, thereby enhancing the support and stability of the adjustable mounting assembly for the first end of the boom.
[0015] In some embodiments of this application, a positioning beam can be further arranged on the base. The positioning beam is configured as a long strip, arranged along the length direction of the base, and located between the two slide rails. Multiple positioning holes are formed on the positioning beam, and the multiple positioning holes are spaced apart along the length direction of the positioning beam. Correspondingly, a crossbeam is provided in the adjustable mounting assembly, configured to connect between the two sliders. A spring pin is installed on the crossbeam, and the positioning of the adjustable mounting assembly is achieved by assembling the spring pin into one of the positioning holes.
[0016] In some embodiments of this application, the distance between the plurality of positioning holes and the fixed mounting assembly can be configured to correspond to the length of different models of booms. Thus, a suitable positioning hole can be selected to install the spring pin according to the actual length of the boom to be rotated, thereby limiting the adjustable mounting assembly so that the distance between it and the fixed mounting assembly is adapted to the length of the boom to be rotated. Then, the two ends of the boom can be accurately installed on the fixed mounting assembly and the adjustable mounting assembly, so that the boom is reliably fixed on the material rack.
[0017] In some embodiments of this application, in order to simplify the fixing operation of the second end of the boom on the material rack, a shaft, a shaft seat, a locking mechanism and a base can be provided in the fixed mounting assembly; wherein, the shaft is used to be installed on the second end of the boom, the shaft seat is used to support the shaft; the locking mechanism is installed on the shaft seat to lock the shaft in the shaft seat; the base can be installed on the bottom of the shaft seat and fixedly assembled with the base of the material rack to form a fixed assembly point.
[0018] In some embodiments of this application, a pressure plate, a rotating handle, and a hook may be provided in the locking mechanism; the pressure plate is rotatably mounted on one side of the shaft seat to press the shaft against the shaft seat, and a pressure groove is formed on the pressure plate; the rotating handle is rotatably mounted on the other side of the shaft seat, in a relative position to the pressure plate; the hook is configured with an inverted U-shaped structure, with its open side rotatably mounted on the rotating handle, rising and falling with the rotation of the rotating handle, so that its closed side either presses against the pressure groove of the pressure plate to lock the pressure plate, thereby locking the shaft in the shaft seat and fixing the first end of the boom to the material rack; or the closed side of the hook disengages from the pressure groove of the pressure plate to release the pressure plate, after which the shaft can be removed from the shaft seat, and the first end of the boom can be detached from the material rack.
[0019] In some embodiments of this application, a storage area may also be provided on the base for storing the shaft to facilitate use by operators.
[0020] In some embodiments of this application, a transfer frame may be further provided in the boom rack, installed on opposite sides of the base, so as to facilitate the grabbing of mechanical equipment such as cranes or trailers, and then to lift or drag the boom rack to transfer the site, thereby realizing the turnover and transportation of the boom.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are mainly reflected in:
[0022] 1. This utility model, by setting an adjustable mounting component on the material rack, allows the position of the mounting component on the material rack to be changed according to the actual length of the boom, enabling it to adapt to and fix booms of different sizes, thereby improving the versatility of the material rack and facilitating management. When boom production fluctuates, the material rack is universal and can be interchanged, preventing waste.
[0023] 2. The material rack of this utility model is equipped with mounting components at both ends of the boom along its length. By fixing the two ends of the boom to the material rack, the boom can be stored firmly and stably on the material rack, thereby achieving safe turnover of the boom.
[0024] 3. The installation components of this utility model adopt a quick-assembly and disassembly structure, which can speed up the loading and unloading speed of the boom on the material rack, improve the boom's turnover efficiency, and facilitate operation by workers.
[0025] 4. The material rack of this utility model adopts a frame structure, which is lightweight and easy to transport. It can be used with mechanized equipment such as cranes or trailers to achieve mechanized turnover and transportation, saving time and effort and making it easy to promote and apply.

[0039] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
[0040] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0041] A rack, also known as a shelf, is a logistics device primarily used for storing and mechanized handling of goods. In this embodiment, the boom rack is mainly used for storing and handling the booms of construction machinery, such as those on excavators and loaders. Considering that different models of construction vehicles use booms of varying lengths, the rack needs to be versatile to reliably store booms of different lengths.
[0042] To make the boom rack more versatile, such as Figure 1 As shown, this embodiment mainly includes components such as a base 100, an adjustable mounting assembly 200, and a fixed mounting assembly 300 in the boom rack.
[0043] The base 100, as the main load-bearing unit of the entire material rack, is horizontally arranged at the bottom of the material rack to support other components of the material rack.
[0044] In some embodiments, the base 100 may be designed as a frame structure to reduce the overall weight of the rack and facilitate handling and transfer.
[0045] Specifically, the base 100 in this embodiment can be designed as a long strip, the length of which should be greater than the length of the longest boom used on construction machinery. The top surface 101 of the base can be formed into a grid to improve the load-bearing strength of the top surface 101. A support leg 102 can be respectively provided at the four corners below the top surface 101 of the base to allow the material rack to be stably erected on the ground or on the pallet of a turnover vehicle. A transverse support beam 103 and a longitudinal support beam 104 can be further provided between two adjacent support leg 102 to increase the support force on the top surface 101 of the base.
[0046] A transfer frame 105 can be installed above the top surface 101 of the base. Two sets of transfer frames 105 can be installed, erected on opposite sides of the base 100. For example, a set of transfer frames 105 can be vertically installed on opposite sides of the base 100 along its length, so as to facilitate the use of cranes, trailers and other mechanized equipment to lift or drag the material rack as a whole for turnover and transportation.
[0047] In some embodiments, the transfer frame 130 can be designed as a height-adjustable gantry to reduce the overall weight of the rack and facilitate handling. Furthermore, the adjustable gantry height allows for the adaptation of different transfer tools for handling the rack.
[0048] For clarity, in this embodiment, the two opposite ends of the material rack base 100 along its length are defined as the head 106 and the tail 107 of the base, respectively. A fixed mounting assembly 300 is installed at the head 106 of the base, and a slide rail 110 is provided at the tail 107 of the base. Figure 4 As shown, the adjustable mounting assembly 200 is slidably mounted on the slide rail 110. Based on the actual length of the boom, the adjustable mounting assembly 200 is slid to adjust the distance between the fixed mounting assembly 300 and the adjustable mounting assembly 200, adapting it to the length of the boom. This allows the opposite ends of the boom in the length direction to be mounted on the fixed mounting assembly 300 and the adjustable mounting assembly 200 respectively, thereby achieving the fixation and storage of the boom on the rack.
[0049] In some embodiments, the slide rail 110 may be designed as a long strip and arranged along the length of the base 100. Two slide rails 110 may be provided, arranged parallel to each other and spaced apart along the width of the base 100, with the spacing between them being greater than the width of the boom end.
[0050] A positioning beam 111 can be installed between the two slide rails 110, such as... Figure 4 As shown. The positioning beam 111 can also be designed as a long strip, arranged along the length of the base 100, and parallel to the two slide rails 110. Multiple positioning holes 112 can be opened on the positioning beam 111, and the multiple positioning holes 112 are arranged at intervals along the length of the positioning beam 111 to lock the sliding position of the adjustable mounting assembly 200.
[0051] In some embodiments, the specific opening position of the positioning hole 112 on the positioning beam 111 can be determined according to the actual length of different models of booms on the market, so that the distance between different positioning holes 112 and the fixed mounting assembly 300 is adapted to the length of different models of booms.
[0052] Of course, in actual use, if the length of the boom that needs to be transported by the material rack in this embodiment cannot be matched with all the positioning holes 112 opened on the material rack, then holes can be drilled at appropriate positions on the positioning beam 111 according to the actual length of the boom, and the number of positioning holes 112 can be increased to meet the usage requirements of different booms.
[0053] Considering the existing boom 400, such as Figure 7 As shown, connecting plates 401 are provided at both ends of the boom 400 that are opposite each other along its length (which can be defined as the first end 410 and the second end 420, respectively). Specifically, two connecting plates 401 are provided at each end, and the two connecting plates 401 are arranged in parallel and opposite to each other, with a relative positional relationship in the width direction of the boom 400. A shaft hole 402 is provided on each of the two connecting plates 401, and a pin can be installed between the two shaft holes 402 to realize the rotational assembly of the boom with other components (such as the stick).
[0054] In view of the above-mentioned structural features of the boom end, this embodiment designs the adjustable mounting assembly 200 and the fixed mounting assembly 300 on the material rack for fixing the boom end, so as to simplify the installation operation of the boom 400 on the material rack.
[0055] In some embodiments, such as Figure 2 As shown, the adjustable mounting assembly 200 can be equipped with main components such as shaft 210, shaft seat 220, locking mechanism 230, and slider 240 to fix the first end 410 of boom 400.
[0056] The shaft 210 can be a pin, installed in the shaft hole 402 of the first end 410 of the boom. The shaft seat 220, the locking mechanism 230 and the slider 240 can be provided in two sets, arranged opposite to each other along the width direction of the base 100, so as to be slidably assembled on the two slide rails 110.
[0057] Specifically, the bearing seat 220 can be installed above the slider 240, using two bearing seats 220 to support both ends of the shaft 210, such as... Figure 5 As shown, the first end 410 of the boom is then positioned between the two bearing seats 220.
[0058] To increase the support strength, support blocks 221 can be further provided on the inner side of each bearing 220, such as... Figure 3 As shown, the middle section of the support shaft 210 (excluding the two ends of the shaft 210) is used.
[0059] A locking mechanism 230 is installed on the bearing seat 220 to lock the shaft 210 in the bearing seat 220.
[0060] In some embodiments, the locking mechanism 230 may include main components such as a pressure plate 231, a rotating handle 232, and a hook 233. The pressure plate 231 and the rotating handle 232 may be positioned on two opposite outer surfaces of the bearing seat 220 and are rotatably assembled with the bearing seat 220. The hook 233 may be mounted on the rotating handle 232 and moves up and down as the rotating handle 232 rotates.
[0061] Specifically, the pressure plate 231 can be connected to the rear side of the bearing seat 220, and after being flipped towards the front side of the bearing seat 220, the shaft 210 can be locked in the bearing seat 220. A pressure groove 234 can be formed on the top surface of the pressure plate 231 for cooperating with the hook 233 to lock the pressure plate 231.
[0062] An adapter plate 235 is installed on the front side of the bearing seat 220. The adapter plate 235 is connected to the rotating handle 232 to realize the rotational assembly between the rotating handle 232 and the bearing seat 220, so that the rotating handle 232 can be flipped up or down relative to the bearing seat 220.
[0063] The hook 233 can be designed as an inverted U-shaped structure, including an open side 236 and a closed side 237 opposite to the open side 236. The open side 236 of the hook is rotatably mounted to the left and right sides of the rotating handle 232 via a pivot 239, with the closed side 237 of the hook positioned above its open side 236. When the rotating handle 232 is flipped upwards, the U-shaped hook 233 rises along with the rotating handle 232. When the closed side 237 of the hook is higher than the pressure groove 234 on the pressure plate 231, the hook 233 is rotated towards the pressure groove 234, so that the closed side 237 of the hook is directly above the pressure groove 234. Then, the rotating handle 232 is flipped downwards, causing the hook 233 to fall along with the rotating handle 232, thereby locking in the pressure groove 234 of the pressure plate 231, thus locking the pressure plate 231 on the bearing 220. Figure 6 As shown.
[0064] When it is necessary to release the locking state of the pressure plate 231, first flip the handle 232 upward to raise the U-shaped hook 233 so that its closed side 237 is away from the pressure groove 234 of the pressure plate 231. Then, rotate the hook 233 so that the closed side 237 of the hook is away from the pressure groove 234, releasing the pressure plate 231 and unlocking the pressure plate 231 on the bearing seat 220.
[0065] In some embodiments, a support base 238 can be provided at the bottom of the rotating handle 232. After the rotating handle 232 is flipped down into place, the support base 238 can press against the slide rail 110 to improve the stability of the locking state of the pressure plate 231.
[0066] The slider 240 is mounted on the bottom of the bearing seat 220 for sliding assembly with the slide rail 110.
[0067] In some embodiments, the slider 240 can be designed as a cylinder, and its cross-sectional shape can be adapted to the cross-sectional shape of the slide rail 110. This allows the slider 240 to be fitted onto the outside of the slide rail 110, preventing the slider 240 from detaching from the slide rail 110.
[0068] For example, the slide rail 110 can be designed as a cuboid structure, the cross-section of which can be rectangular or square. Correspondingly, the slider 240 is configured as a hollow cuboid structure with openings at the front and back, and the shape of the openings matches the cross-sectional shape of the slide rail 110, for example, also being rectangular or square. The slider 240 is arranged around the slide rail 110 to move back and forth along the length of the slide rail 110.
[0069] In this embodiment, the adjustable mounting assembly 200 includes two sliders 240, each mounted on one of two slide rails 110. A crossbeam 250 connects the two sliders 240. Figure 3 As shown, the crossbeam 250 is located above the positioning beam 111 arranged at the tail of the base 107, and forms a cross relationship with the positioning beam 111, as shown. Figure 6 As shown.
[0070] A spring pin 251 is installed on the crossbeam 250, with its telescopic end 252 passing through the crossbeam 251 and protruding from its bottom. When the adjustable mounting assembly 200 is slidable, the telescopic end 252 of the spring pin is in a retracted state and slides along the top surface of the positioning beam 111. When the telescopic end 252 of the spring pin slides to the position of the positioning hole 112 on the positioning beam 111, the telescopic end 252 of the spring pin automatically pops out under the action of elastic restoring force and inserts into the positioning hole 112 to lock the position of the adjustable mounting assembly 200 on the base 100.
[0071] For fixed-mount component 300, such as Figure 1 As shown, the specific design can be based on some of the structures of the adjustable mounting assembly 200, including main components such as shaft 310, shaft seat 320, locking mechanism 330, and base 340.
[0072] The shaft 310 is used to be installed in the shaft hole of the second end 420 of the boom 400, in conjunction with... Figure 7 As shown. A bearing seat 320 is mounted above the base 340 to support the shaft 310. A locking mechanism 330 is mounted on the bearing seat 320 to lock the shaft 310 within the bearing seat 320. The base 340 is mounted on the head 106 of the base 100 and is fixed in position, not adjustable.
[0073] In some embodiments, the base 340 can be designed as a long strip, arranged along the width direction of the base 100, and fixedly assembled with the base 100. Two bearing seats 320 are mounted on the base 340, configured to be in a relative position along the width direction of the base 100 to support both ends of the shaft 310. The distance between the two bearing seats 320 is greater than the width of the second end 420 of the boom 400, such as... Figure 7 As shown, this allows the second end 420 of the boom 400 to be positioned between the two bearing seats 320. A locking mechanism 330 is installed on each bearing seat 320 to lock both ends of the shaft 310 into the two bearing seats 320 respectively, thereby fixing the second end 420 of the boom 400 onto the material rack.
[0074] The locking mechanism 330 in the fixed mounting assembly 300 can adopt the same structural design as the locking mechanism 230 in the adjustable mounting assembly 200, which will not be described in detail in this embodiment.
[0075] To facilitate the use of the material rack by operators, a storage area 108 can be further provided on the base 100 of the material rack, such as... Figure 1 As shown, for example, a position is provided on the top surface 101 of the base near the slide rail 110 to store shafts 210, 310 for installation in the adjustable mounting assembly 200 and the fixed mounting assembly 300.
[0076] Industrial applicability
[0077] The boom of the hydraulic excavator used in this embodiment for material rack turnover transportation will be used as an example for explanation.
[0078] Combination Figures 1 to 7 As shown, two shafts 210 and 310 are taken out from the storage area 108 on the material rack base 100 and installed at the first end 410 and the second end 420 of the boom 400, respectively.
[0079] Pull up the spring pin 252 in the adjustable mounting assembly 200 to release the locking state of the adjustable mounting assembly 200 on the base 100.
[0080] Slide the adjustable mounting component 200 to adjust the distance between the adjustable mounting component 200 and the fixed mounting component 300 to fit the actual length of the boom 400. Then, insert the spring pin 252 into the positioning hole 112 corresponding to the current position of the adjustable mounting component 200 to lock the position of the adjustable mounting component 200.
[0081] Open the locking mechanisms 230 and 330 in the adjustable mounting assembly 200 and the fixed mounting assembly 300, and lift the boom 400 to move it directly above the material rack base 100. Then, lower the boom 400 and place the shafts 210 and 310 installed at the two ends of the boom into the shaft seats 220 and 320 of the adjustable mounting assembly 200 and the fixed mounting assembly 300, respectively.
[0082] Close the locking mechanisms 230 and 330, and use the pressure plates in the locking mechanisms 230 and 330 to lock the two ends of the shafts 210 and 310 in the shaft seats 220 and 320, so as to fix the two ends of the boom 400 on the material rack.
[0083] Using mechanized equipment such as cranes or trailers, the transfer frame 105 in the material rack is grabbed, and the material rack and the boom 400 fixed on it are lifted as a whole for transfer or transportation to other sites.
[0084] Once the material rack and boom 400 reach their destination, open the locking mechanisms 230 and 330 in the adjustable mounting assembly 200 and the fixed mounting assembly 300, flip open the pressure plate, and release the bearing seats 220 and 320. Afterward, the boom 400 can be removed from the material rack by a crane, completing the turnover and transportation of the boom 400.
