Description

Technical Field

[0001] This utility model relates to the technical field of forklift testing equipment, specifically a flexible load device for forklift testing. Background Technology

[0002] Currently, the loads used in forklift reinforcement tests are all fixed-weight loads that cannot be adjusted. Because of their fixed weight parameters, these loads cannot be flexibly adjusted and configured according to different test conditions and requirements, resulting in low efficiency and cumbersome operation. Furthermore, to meet diverse test requirements, various fixed loads of different weights must be stored and placed in the workshop test area for extended periods. This increases the number of loads piled up in the workshop test area, occupies corresponding work space, wastes workshop layout space, and also negatively impacts the overall aesthetics of the workshop, failing to meet standardized workshop management requirements.

[0007] Preferably, the basic load channel steel frame further includes a supporting channel steel connected to the lower sealing plate, and the two ends of the supporting channel steel are connected to the vertical channel steel. The lower sealing plate is connected to two load limiting square tubes of No. 3 at symmetrical positions about the two sides of the supporting channel steel. The load limiting square tubes of No. 3 and the supporting channel steel symmetrically form two spaces for limiting the No. 3 load.

[0008] Preferably, the third load is a 0.1t load or a 0.2t load.

[0009] Preferably, an off-center loading assembly is provided between the upper sealing plate and the first load to drive the center of gravity of the first load to shift; the off-center loading assembly includes an adjustment groove on the upper sealing plate, and a pin hole is provided on the upper sealing plate near the adjustment groove. Two sets of channel steel rails are symmetrically connected along the long side of the adjustment groove on the bottom surface of the upper sealing plate near the adjustment groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this embodiment, the horizontal direction of the lower horizontal channel steel 11 is taken as the reference, and the vertical direction of the lower vertical channel steel 13 is taken as the reference.

[0029] Please see Figure 1-8 In this embodiment of the present invention, a flexible load device for forklift testing includes a basic load channel steel frame 1, a lower sealing plate 7 connected to the bottom of the basic load channel steel frame 1, and an upper sealing plate 6 connected to the top of the basic load channel steel frame 1.

[0030] The upper sealing plate 6 is equipped with a first load 2, and the upper sealing plate 6 is symmetrically connected with a second load 3 on both sides of the first load 2. The lower sealing plate 7 is symmetrically equipped with a third load 4.

[0031] Specifically, the upper end plate 6 has two lifting lugs 5 fixedly connected to its two sides at an angle. The angled lifting lugs 5 design can ensure better stability when lifting the basic load channel steel frame 1. The bottom of the lower end plate 7 is fixedly connected to two fork sleeves 8 to ensure the stability of the basic load channel steel frame 1 during forklift movement and prevent it from slipping or shifting. The bottom and top of the basic load channel steel frame 1 can be fixedly connected to the upper end plate 6 and the lower end plate 7 by welding. The basic load channel steel frame 1 also includes a support channel steel 15 fixedly connected to the lower end plate 7, and the two ends of the support channel steel 15 are connected to the vertical channel steel 12, which can improve the structural strength of the basic load channel steel frame 1. During the reinforcement test, the basic load channel steel frame 1, the lifting lugs 5, the upper end plate 6, the lower end plate 7, the fork sleeves 8 and the support channel steel 15 are fixedly connected as a whole and can be used as a basic load. The weight of the basic load is preferably 0.8t. When different loads are required for different test conditions, additional loads can be added to the base load as needed. The loads are divided into three categories: load 1 (2), load 2 (3), and load 3 (4). Load 1 (2) is located in the middle of the upper sealing plate 6. Load 2 (3) is divided into two groups and is set on the upper sealing plate 6 symmetrically about load 1 (2). Load 2 (3) is detachably connected to the upper sealing plate 6, preferably by bolts. Load 3 (4) is also divided into two groups and symmetrically set on both sides of the support channel steel 15. When setting the load weight, load 1 (2), load 2 (3), and load 3 (4) can be combined arbitrarily according to the specific test load requirements. The combination methods include single loads, loads consisting of any two items, or loads consisting of all three items. Multiple load weights can be configured according to the test requirements. During the test, there is no need to replace the entire load set; only the combination as needed can meet diverse test conditions. The operation is flexible and quick, greatly improving test efficiency.

[0032] In a preferred embodiment, load 2 can be set to 0.5t, load 3 to 0.05t, and load 4 to either 0.1t (load 41) or 0.2t (load 42). Based on the above configuration, the load weight can be configured to cover the range of 0t-1t through any combination of the above methods. Furthermore, the base load weight is preferably 0.8t, and the adjustment range of the entire flexible load device covers 0.8t to 1.8t. Various loads with different weight specifications can be formed through different combinations.

[0033] Furthermore, such as Figures 1 to 3 As shown, the basic load channel steel frame 1 includes a lower transverse channel steel 11 arranged in parallel. The lower sealing plate 7 is connected to the lower transverse channel steel 11. Two sets of support frames are connected to both sides of the lower sealing plate 7. Each set of support frames includes several vertical channel steels 12 connected along the length direction of the lower transverse channel steel 11. The vertical channel steels 12 at the ends of the two sets of support frames are connected to the lower longitudinal channel steel 13. The ends of the two sets of support frames away from the lower sealing plate 7 are connected to the upper channel steel 14 with an opening shape.

[0034] Specifically, the upper ends of the two sets of lower transverse channel steels 11 arranged in parallel are fixedly connected to the lower sealing plate 7. Several vertical channel steels 12 are fixedly connected to both sides of the lower sealing plate 7 along the length of the lower transverse channel steels 11. Preferably, there are three vertical channel steels 12 on one side of the lower sealing plate 7, with two located at both ends of one side of the lower sealing plate 7 and the remaining one fixedly connected to the middle position of one side of the lower sealing plate 7. Through this structure, the overall structural strength of the foundation load channel steel frame 1 can be further enhanced. The ends of the two sets of support frames away from the lower sealing plate 7 are fixedly connected to the upper channel steel 14 with an opening shape, so that the various parts of the foundation load channel steel frame 1 are fixedly connected to form a whole, which is convenient for hoisting.

[0035] like Figure 2 As shown, the lower sealing plate 7 is connected to two load limiting square tubes 9 at symmetrical positions on both sides of the support channel steel 15. The load limiting square tubes 9 and the support channel steel 15 symmetrically form two spaces for limiting the load 4.

[0036] Specifically, two spaces for limiting the No. 3 load 4 are symmetrically formed between the No. 3 load limiting square tube 9 and the support channel steel 15. The horizontal cross-sectional shape of this space should be consistent with the horizontal cross-sectional shape of the bottom of the No. 3 load 4, preferably rectangular. The horizontal cross-sectional area of ​​this limiting space should be slightly larger than the horizontal cross-sectional area of ​​the bottom of the No. 3 load 4, so as to facilitate the placement of the No. 3 load 4 and achieve the limiting effect. It can be set according to experience. The No. 3 load 4 is set as two types: 0.1t load 41 and 0.2t load 42. The shapes of both loads should meet the above requirements. The limiting space is divided into two groups and symmetrically arranged about the support channel steel 15, so that the two groups of No. 3 load 4 can exert a more uniform force on the forks and ensure overall balance.

[0037] Furthermore, such as Figures 1 to 4 As shown, an off-center loading assembly 10 is provided between the upper sealing plate 6 and the first load 2 to drive the center of gravity of the first load 2 to shift. The off-center loading assembly 10 includes an adjustment groove 101 opened on the upper sealing plate 6, and a pin hole 102 is opened on the upper sealing plate 6 near the adjustment groove 101. Two sets of channel steel rails 103 are symmetrically connected along the long side of the adjustment groove 101 on the bottom surface of the upper sealing plate 6 near the adjustment groove 101. An off-center loading moving seat 104 is rolled on both sets of channel steel rails 103, and a corresponding pin hole 102 is opened on the off-center loading moving seat 104. A placement opening 105 is opened on the top of the off-center loading moving seat 104.

[0038] like Figure 5 As shown, the first load 2 includes an orifice 21 and a limiting member 22 connected to the orifice 21, and the limiting member 22 and the placement opening 105 form a limiting fit.

[0039] Specifically, in forklift reinforcement tests, eccentric loads are sometimes required to test the forklift's balance stability. This application addresses this by setting an eccentric load assembly 10, where a limiting member 22 can be inserted through the placement opening 105. The horizontal cross-sectional shape of the limiting member 22 should be the same as the shape of the placement opening 105, and the cross-sectional area of ​​the limiting member 22 should be slightly smaller than the area of ​​the placement opening 105. This ensures that the limiting member 22 can be inserted into the placement opening 105 while achieving a limiting effect. This requirement is based on the experience of those skilled in the art. When eccentric loading is required, first remove the component inserted on the upper... The pin on the pin hole 102 on the sealing plate 6 and the off-center load moving seat 104 is used to release the off-center load moving seat 104 from its limit. Then, according to the degree of eccentricity required for the test, the off-center load moving seat 104 is moved to the required position. Then, the pin is reinserted into the pin hole 102 on the upper sealing plate 6 and the off-center load moving seat 104 to complete the re-limitation of the off-center load moving seat 104 and complete the off-center load operation. It should be noted that the weight of the off-center load moving seat 104 should be included in the weight of the base load. Preferably, the total weight of the base load is 0.8t.

[0040] By setting the off-center load component 10, the requirements for off-center load testing can be further met while ensuring that the flexible load is adjustable. The operation is simple, which enriches the testing functions of this application and improves its practical value.

[0041] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0042] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
