Description

Technical Field

[0001] This utility model belongs to the field of forklift assembly technology, specifically relating to a height adjustment device for the inner wall panel of a forklift body. Background Technology

[0002] The forklift frame is a crucial structure for bearing and transmitting working loads. It typically employs a box-type structure, including components such as the front fender, front panel, body, and tailstock. The body, welded from steel plates, is a box-shaped structure with high rigidity, supporting most of the forklift's weight and the weight of its cargo, as well as withstanding forces, moments, and impact loads from other components. The tailstock connects to the rear end of the body's inner wall panel, providing support and securing the body.

[0003] When assembling the chassis, adjustments to the height and position of the inner wall panels are necessary. Because the rear end of the inner wall panels is a protruding structure and quite heavy, the current method primarily involves using a crane to lift and lower or raise the rear end of the inner wall panels for position adjustment. However, this crane lifting method is complex, slow, and cannot achieve fine-tuning, resulting in inconsistent positioning accuracy. Furthermore, this method requires additional manpower and equipment, increasing production costs and time.

[0004] Therefore, improving the height adjustment method of the inner wall panel is key to improving the assembly efficiency and precision of the forklift frame. This invention provides a height adjustment device to achieve rapid, flexible, and precise adjustment of the inner wall panel. Utility Model Content

[0005] This invention provides a height adjustment device that can quickly and effectively adjust the tailplate height with improved accuracy.

[0006] The specific technical solution of this utility model is as follows:

[0007] A height adjustment device for the inner wall panel of a forklift body includes a support frame. An adjustment assembly is fixedly mounted on the support frame. The adjustment assembly includes an operating platform and an upper connecting plate fixedly connected to the support frame. A transverse sliding assembly is horizontally movably connected to the operating platform. A support block is vertically movably connected to the upper connecting plate. The bottom end face of the support block and the top end face of the transverse sliding assembly are both mutually cooperating inclined surfaces that abut against each other. The transverse sliding assembly is connected to a driving device that drives it to move horizontally on the operating platform, thereby causing the support block to move vertically on the upper connecting plate.

[0008] In a further embodiment, a pair of lower limit blocks are fixedly provided on the top surface of the operating table to form a lower guide groove, and the bottom end of the transverse assembly is embedded in the lower guide groove for movement.

[0009] In a further embodiment, limiting pins are fixedly installed on the operating platforms at both ends of the lower guide groove, and the limiting pins are used to limit the movement distance of the transverse assembly.

[0010] In a further embodiment, the operating console is fixedly connected to the support frame via a connecting seat.

[0011] In a further embodiment, the driving device includes a fixed base fixed to the operating table, a driving rod threadedly connected to the fixed base, one end of the driving rod being fixedly connected to the transverse assembly, driving the transverse assembly to move horizontally on the operating table.

[0012] Preferably, a handle is mounted on the other end of the drive rod.

[0013] In a further embodiment, the transverse assembly includes left and right moving blocks arranged opposite to each other, the left and right moving blocks being connected by a connecting shaft, and a plurality of rollers being sleeved on the connecting shaft located between the left and right moving blocks, the bottom end face of the support block being in contact with the rollers.

[0014] In a further embodiment, a pair of upper limit blocks are fixedly provided on the upper connecting plate to form an upper guide groove, and one end of the support block is embedded in the upper guide groove for movement; the shape of the support end of the support block is adapted to the rear end of the inner wall panel and is used to support the rear end of the inner wall panel.

[0015] This application utilizes a sloped fit design between the support block and the lateral movement assembly to ensure that the support block can move up and down during the lateral movement of the lateral movement assembly. Therefore, during forklift assembly, the rear end of the inner wall panel rests on the support block, driving the lateral movement assembly forward or backward, which in turn translates into the up and down movement of the support block, ultimately adjusting the height of the rear end of the inner wall panel, thus facilitating its assembly.

[0016] Therefore, the height adjustment device of this utility model is flexible and convenient to operate, and can make fine adjustments to the height of the rear end of the inner wall panel and control its accuracy; in addition, this device has a direction conversion function, that is, it can be operated in the horizontal direction to realize vertical movement; and it can bear the weight of the plate.

[0026] Support frame 200, inner wall panel 300. Detailed Implementation

[0027] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," and "fixed installation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] See Figure 1-5 A height adjustment device for the inner wall panel of a forklift box includes a support frame 200, on which an adjustment component 100 is fixedly mounted. The adjustment component 100 is as follows: Figure 2As shown, it includes an operating platform 2 and an upper connecting plate 3 fixedly connected to a support frame. A horizontally movable transverse assembly 8 is connected to the operating platform 2, and a vertically movable support block 4 is connected to the upper connecting plate 3. The bottom surface of the support block 4 and the top surface of the transverse assembly 8 are both mutually cooperating inclined surfaces that abut against each other. The transverse assembly 8 is connected to a driving device 7 that drives it to move horizontally on the operating platform 2. Since the contact surfaces of the support block 4 and the transverse assembly 8 are inclined surfaces, and the inclined surfaces of the two are opposite to each other and can fit completely, the horizontal movement of the transverse assembly 8 will drive the support block 4 to move vertically on the upper connecting plate 3. This achieves the height adjustment of the adjustment component 100. When the forklift body is assembled, the rear end of the inner wall panel 300 is mounted on the top of the support block 4, thereby achieving the height adjustment of the rear end of the inner wall panel 300.

[0030] In another embodiment, a pair of lower limit blocks 6 are fixedly provided on the top surface of the operating table 2 to form a lower guide groove, and the bottom end of the transverse assembly 8 is embedded in the lower guide groove for movement. The structure of the lower limit block 6 is as follows: Figure 5 As shown, it is fixed to the operating table 2 by fixing bolts passing through fixing holes 62. A set of lower limit blocks 6 have protrusions 61 on the upper edges of opposite sides. The bottom of the left moving block 81 and right moving block 82 of the transverse moving assembly 8 are provided with sliding grooves 86 that match the protrusions 61. That is, the movement of the transverse moving assembly 8 is more stable by the cooperation and sliding of the protrusions 61 and the sliding grooves 86, and it also plays a guiding role.

[0031] Limiting pins 9 are fixed on the operating platforms 2 located at both ends of the lower guide groove. The limiting pins 9 are used to limit the movement distance of the transverse assembly 8. That is, the extension line of the limiting pins 9 in the lower guide groove ensures that the transverse assembly 8 and the support block 4 are always in contact.

[0032] In another specific embodiment, the operating table 2 is fixedly connected to the support frame 200 via the connecting seat 1 and fixing bolts. The upper connecting plate 3 is also fixedly installed on the support frame 200 via fixing bolts.

[0033] like Figure 2 As shown, the driving device includes a fixed base 71 fixed on the operating table 2. A threaded driving rod 72 passes through the middle of the fixed base 71. One end of the driving rod 72 is fixedly connected to the transverse assembly 8. By rotating the driving rod 72, it drives the transverse assembly 8 to move horizontally on the operating table 2. To facilitate the operation of the driving rod 72, a handle 73 is installed at the other end of the driving rod 72.

[0034] like Figure 2As shown, the transverse assembly 8 includes a left-moving block 81 and a right-moving block 82 arranged opposite to each other. The left and right moving blocks are connected by a connecting shaft 83. Multiple rollers 84 are sleeved on the connecting shaft 83 located between the left and right moving blocks, and the rollers 84 can rotate freely on the connecting shaft. In actual use, the connecting shaft 83 can be passed through the left moving block, the rollers 84, and the right moving block in sequence, and both ends are fixed with fasteners 85 (such as fixing nuts). The bottom end face of the support block 4 is in contact with the rollers 84, thereby reducing friction. When the transverse assembly 8 moves horizontally, its top end face keeps the support block 4 in contact, allowing the support block 4 to move in the vertical direction.

[0035] In another embodiment, a pair of upper limit blocks 5 are fixedly mounted on the upper connecting plate 3 to form an upper guide groove. The structure of the upper limit blocks 5 is the same as that of the lower limit blocks 6. One end of the support block 4 is embedded in the upper guide groove for movement. The support end 41 of the support block 4 is shaped to match the rear end of the inner wall plate 300 and is used to support the rear end of the inner wall plate 300. Upper sliding grooves 43 are symmetrically provided on both sides of the fixed end 42 of the support block 4, which cooperate with the recesses on the upper limit blocks 5 to improve the movement stability and guidance of the support block 4.

[0036] In this embodiment, the design of the support block 4 and the inclined surface of the transverse assembly 8 ensures that the support block can move up and down during the transverse movement of the assembly. Therefore, during the assembly of the forklift body, the rear end of the inner wall panel 300 rests on the support end 41 of the support block (e.g., Figure 6 As shown, by rotating the drive rod 72 through the handle 73, the transverse assembly can be moved forward or backward, which is then converted into the up and down movement of the support block, and finally drives the height adjustment of the rear end of the inner wall panel 300, thus facilitating its assembly.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
