Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment assembly tools, specifically to a bolt pallet cart for crane assembly. Background Technology

[0002] In the existing production process architecture, the fastener supply unit and the assembly unit are often physically separated. Before the assembly unit can start operations, it must first initiate a material requisition process with the supply unit, and the fasteners can only be received after the requisition request is approved.

[0003] For the supply of hardware fasteners, the current model mostly involves centralized collection and unified distribution of multiple categories. Due to the fragmented nature of these components, manual counting is tedious and prone to errors, easily leading to misdelivery or omissions of individual parts during the handover process. Such issues are often only identified after the product has entered the next process, requiring subsequent problem feedback, requisition requests, and secondary deliveries to retrieve the missing parts. This significantly reduces overall operational efficiency and delays the overall project schedule. Some units have adopted a strategy of transporting spare parts to mitigate the risk of errors or omissions, but this increases the workload and labor costs associated with transportation, and may also lead to redundant inventory and resource waste.

[0004] To address the aforementioned issues, patent document CN209852364U discloses a bolt material cart for the yaw installation process of a wind turbine, comprising: a frame and casters mounted on the lower end of the frame. The frame includes a square base plate, four angle steel columns fixedly mounted on the upper ends of the four corners of the base plate, four lifting lugs mounted on the tops of the four angle steel columns, two fixed side plates fixedly mounted on the left and right sides of the upper end of the base plate, a transverse support edge mounted on the top of the two fixed side plates, and multiple layers of square single-layer bolt trays stacked above the transverse support edge. These single-layer bolt trays are located between the four angle steel columns. Transverse reinforcing ribs are provided on both the front and rear sides of the upper part of the frame. The transverse reinforcing ribs are fixedly connected to the corresponding angle steel columns. The transverse reinforcing ribs are adjacent to and above the top layer of single-layer bolt trays.

[0005] However, this solution has not yet solved the following technical problems: the types of items it transports are relatively limited and restricted to screws; when multiple pallets are stacked together for transport, it is not easy to check whether any parts are missing or incorrect.

[0006] Therefore, it is necessary to design a new device to solve the above technical problems. Utility Model Content

[0007] This utility model provides a bolt pallet cart for crane assembly, which aims to solve the technical problem that material carts in the prior art cannot simultaneously and accurately transport multiple fastening parts required for assembly.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A bolt pallet cart for crane assembly includes a base equipped with rollers, a stepped bracket on the base, the stepped bracket including a first bracket and a second bracket, wherein the first bracket is higher than the second bracket; the bolt pallet cart also includes one or more first tooling plates, the first tooling plates being detachably mounted on the first bracket and / or the second bracket; the first tooling plate has multiple rows of insertion holes for placing bolts in the width direction; the bolt pallet cart also includes one or more second tooling plates, the second tooling plates being detachably mounted on the first bracket and / or the second bracket; and multiple vertical columns for placing washers and / or nuts are also vertically arranged on the upward-facing side of the second tooling plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Using multiple tooling plates to carry various hardware components such as bolts, each component is placed in its designated area according to its type and specifications. This facilitates quick verification of whether a certain type of component is fully supplied and helps assembly personnel quickly locate components, effectively improving work efficiency. The stepped bracket has multiple mounting holes, allowing multiple tooling plates to be carried at a time, making it less likely to cause errors or omissions when transporting large quantities of hardware components at once.

Detailed Implementation

[0012] The following is combined with Figures 1 to 7 The present invention will be further described in detail below with reference to specific embodiments.

[0013] A bolt pallet truck for crane assembly collects hardware parts, such as bolts, washers, and nuts, from multiple tooling plates and then transports them via the bolt pallet truck. This reduces the risk of incorrect or missing parts while transporting large quantities of hardware parts.

[0014] Specifically, such as Figure 1 and Figure 2 As shown, the bolt pallet cart of this utility model includes a base 100, and the bottom surface of the base 100 is equipped with rollers 105.

[0015] From a functional optimization perspective, to improve the stability and smoothness of the bolt pallet truck during the pushing process, the number of rollers 105 can usually be set to 4 and symmetrically arranged at the four corners of the base 100. If it is necessary to further enhance the load capacity of the bolt pallet truck, the number of rollers 105 can also be adjusted to 6 or even 8. Their arrangement is not limited to being distributed only at the four corners of the base 100, as long as the basic requirement of smooth operation of the bolt pallet truck is met.

[0016] The top surface of the base 100 is provided with three pairs of vertically extending support rods at intervals. Among them, a pair of long support rods are arranged near one end of the base 100, and a pair of short support rods are arranged near the other end of the base 100, and are distributed opposite to the long support rods; it also includes a pair of intermediate support rods, which are about the same length as the long support rods, and are arranged between the aforementioned long support rods and short support rods.

[0017] Brackets are installed at the top of the long support rod and the middle support rod, as well as at the top of the short support rod and the middle of the middle support rod, forming a stepped bracket 200. The taller bracket is the first bracket 201, and the shorter bracket is the second bracket 202. The advantage of this arrangement is that the first bracket 201 can be used to place longer bolts, while washers or nuts can be placed on the second bracket 202, saving space and making it easier for users to access parts.

[0018] Continue to refer to Figures 4 to 6The bolt pallet truck also includes at least one first tooling plate 301, which is detachably mounted on the first bracket 201 and / or the second bracket 202.

[0019] Specifically, in some embodiments, the top of the first bracket 201 and the second bracket 202 are pre-set with a plurality of mounting holes 401, and the first tooling plate 301 is correspondingly provided with a plurality of positioning holes 404 adapted to the mounting holes 401. When the first tooling plate 301 needs to be assembled to the first bracket 201 and / or the second bracket 202, the positioning holes 404 are first aligned with the mounting holes 401, and then the positioning bolts 405 are inserted through both; if necessary, the positioning bolts 405 can be tightened to further fix the first tooling plate 301.

[0020] To further improve the fixing effect, the mounting holes 401 can be arranged in pairs on opposite sides of the first bracket 201 or the second bracket 202, and their number can be adjusted according to the specifications of the bolt pallet truck.

[0021] For example, for a bolt pallet cart whose lateral width of the stepped bracket 200 can accommodate three first tooling plates 301, three pairs of mounting holes 401 can be provided on opposite sides of the first bracket 201, and each pair of mounting holes 401 can be fixed with a first tooling plate 301 by positioning bolts 405; or six pairs of mounting holes 401 can be provided, and each pair of mounting holes 401 can be fixed with a first tooling plate 301 by positioning bolts 405 to further improve stability.

[0022] In other embodiments, cable ties may be used instead of positioning bolts 405: after passing the cable ties through the positioning hole 404 and the mounting hole 401, they are simultaneously tied to the outer edge of the first tooling plate 301 and the edge of the first bracket 201 or the second bracket 202.

[0023] The first tooling plate 301 has multiple rows of insertion holes 402 in the width direction for placing bolts to be transported.

[0024] In some embodiments, the first tooling plate 301 is made of nylon sheet, and its insertion hole 402 and positioning hole 404 are both formed by drilling. Compared with metal materials, the advantage of using nylon sheet is that during the process of inserting the bolt into the insertion hole 402, the nylon material can effectively prevent the external thread of the bolt from being damaged due to collision with the first tooling plate 301.

[0025] In some implementations, such as Figure 4 As shown, all the insertion holes 402 on the first tooling plate 301 have the same size and can only accommodate bolts of a single specification. This technical solution can be adapted to application scenarios that require the use of bolts of the same specification in batches, and can meet the centralized storage and transportation needs of bolts of a specific model.

[0026] In other embodiments, the insertion holes 402 of the same tooling plate can also be configured to include a variety of different specifications to accommodate scenarios that require the installation of multiple types of bolts at a time.

[0027] like Figure 5 As shown, the first tooling plate 301 is provided with multiple rows of insertion holes 402, wherein the insertion holes 402 in the same row have the same size, and the insertion holes 402 in different rows have different sizes.

[0028] Specifically, the first tooling plate 301 in the figure can be divided into two regions: the first is the left region, in which the size of all insertion holes 402 is constant; the second is the right region, in which the size of each column of insertion holes 402 gradually increases along the length of the first tooling plate 301, starting from the rightmost column.

[0029] In another embodiment, the first tooling plate 301 does not have a region where the size of the aforementioned insertion holes 402 is constant. The arrangement of the insertion holes 402 is such that, along the length direction of the first tooling plate 301, the size of each column of insertion holes 402 gradually increases, forming a size gradient structure throughout the entire region.

[0030] In some embodiments, in order to facilitate quick differentiation of bolts with similar appearance and size, a mark can be set in the area adjacent to the insertion hole 402; the mark can be implemented by means of including but not limited to pasting labels, laser etching marks, or manual printing marks, so as to improve the accuracy and efficiency of bolt picking through visual differentiation.

[0031] In some embodiments, the bolt pallet cart is also equipped with a plug 403, which can be fitted into the insertion hole 402 to disable the function of the corresponding insertion hole 402. When the insertion hole 402 of the first tooling plate 301 does not need to be fully occupied, the unused insertion hole 402 can be sealed by the plug 403, effectively preventing the accidental insertion of excess bolts; at the same time, this design can simplify the verification process in the bolt transportation process and improve the efficiency of bolt counting.

[0032] The bolt pallet truck also includes at least one second tooling plate 302, which is detachably mounted on the first bracket 201 and / or the second bracket 202.

[0033] Specifically, the top of the first bracket 201 and the second bracket 202 are pre-set with a number of mounting holes 401, and the second tooling plate 302 is correspondingly provided with a number of positioning holes 404 that are adapted to the mounting holes 401, so that they can be fixed on the first bracket 201 or the second bracket 202 by positioning bolts 405.

[0034] The second tooling plate 302 also includes a column 406, which is vertically arranged on one side of the second tooling plate 302 for placing washers and / or nuts.

[0035] In some embodiments, the column 406 is fixed to the second tooling plate 302 by adhesive. In other embodiments, the second tooling plate 302 and the column 406 are made of metal, and the column 406 is fixed to the second tooling plate 302 by welding.

[0036] In some embodiments, the number of uprights 406 is not limited to one, and they have different specifications. For example, on a second tooling plate 302, there are three specifications of uprights 406, including: 4066 uprights with a diameter of 40mm and a length of 500mm; 4067 uprights with a diameter of 30mm and a length of 400mm; and 4062 uprights with a diameter of 10mm and a length of 300mm.

[0037] In some embodiments, the outer circumferential surface of the column 406 is machined with a threaded structure and equipped with a suitable column nut 407. After the washer to be transported is fitted onto the column 406, the column nut 407 is tightened onto the threaded section of the column 406 to prevent the washer or nut from falling off due to collisions caused by the bolt pallet truck.

[0038] The thread can be set along the entire outer circumference of the column 406 so that the column nut 407 can be closer to the bottom when there are fewer gaskets or nuts that need to be transferred; or the threaded section can be set only at the upper end of the column 406 to avoid scratching damage when the gasket is installed due to the full distribution of the thread, or jamming when it is removed.

[0039] In some embodiments, a number of insertion holes 402 may also be provided on the second tooling plate 302 to adapt to diverse transportation scenario requirements. The number, specifications, and arrangement of the insertion holes 402 can be implemented with reference to the setting standard of the insertion holes 402 on the first tooling plate 301, and will not be described in detail here.

[0040] In some embodiments, the base 100 is provided with an upwardly extending frame 101 at its edge, which together with the base 100 forms a tray-shaped support structure.

[0041] In one embodiment, the base 100 and the frame 101 are manufactured using an integral molding process, with no seam between them.

[0042] In another embodiment, the base 100 is made by secondary processing of a rectangular plate: first, the four corners of the rectangular plate are cut off to remove the smaller square pieces, and then the four sides of the plate are bent upward along the preset creases so that the bent sides enclose to form a frame 101, thus completing the forming of the tray-shaped structure.

[0043] In another embodiment, the base 100 is made of a square metal plate, and the four side frames 101 are made of long and narrow rectangular metal plates. The rectangular metal plates have long and wide sides, and the length of the long side matches the side length of the base 100. During assembly, the long side of a single side frame 101 is first fixed to one side of the base 100 by welding; then, the two wide sides of the side frame 101 are welded to the corresponding wide sides of the two adjacent side frames 101, respectively. By welding side by side, the four side frames 101 are enclosed, finally forming a tray-shaped base 100. It should be noted that the tray-shaped base 100 can be obtained in various ways; the above are only three typical technical solutions, and others will not be elaborated here.

[0044] In some embodiments, each of the two opposing frame pieces 101 has two mounting holes 104. For example... Figure 3 As shown, the four lifting holes 104 are symmetrically distributed with respect to the center of the base 100.

[0045] In some implementations, such as Figure 3 As shown, the base 100 is also provided with a partition 102 inside, which divides the base 100 into multiple independent placement areas 103, so as to carry additional parts or tools and be able to quickly access them according to their location.
