[0002] According to the latest ABS specifications, the lifting lugs of the skids need to be load tested, and the test load is twice the skid lifting weight.

[0035] Example 1

[0036] In a typical implementation of the present invention, Figure 1 As shown, the present embodiment discloses a skid-mounted lifting eye load testing device, including a linear drive device, a shackle, a force measuring device, a tooling beam 3 and a limiting device; in the present embodiment, the force measuring device adopts an electronic scale 8, the connecting buckle adopts a shackle, and the linear drive device adopts a jack, the jacks include two, namely, a first jack 1 and a second jack 2, which are fixed on the main frame beam 11, drive the tooling beam 3, and the tooling beam 3 is arranged above the main frame beam 11, and the two are parallel to each other, and a tooling lifting eye 6 is installed at the bottom of the tooling beam 3, and the tooling lifting eye 6 is located directly above the skid lifting eye 10; the electronic scale 8 is connected to the tooling lifting eye 6 and the skid lifting eye 10 through the shackle; the limiting device includes a first limiting device 4 and a second limiting device 5; the first jack 1 and the second jack 2 each pass through the corresponding first limiting device 4 and second limiting device 5 to drive the tooling beam 3; these components cooperate with the skid lifting eye 10 to realize the load test process, and the specific structure is as follows:

[0037] The above-mentioned jacks are hydraulic jacks, and there are two of them, namely the first jack 1 and the second jack 2. The first jack 1 and the second jack 2 are symmetrically placed on the left and right sides of the pry block lifting ear 10 along the width direction of the pry block lifting ear 10. The specific position needs to be confirmed according to the length of the tooling crossbeam 3; along the thickness direction of the pry block lifting ear 10, they are aligned with the center line of the main frame beam 11 of the pry block, wherein the pry block lifting ear 10 is the product lifting ear that needs to be subjected to load testing;

[0038] The number of the above-mentioned tooling beam 3 is 1, which is placed directly above the first jack 1 and the second jack 2. Along the width direction of the pry block lifting ear 10, the length center of the tooling beam 3 is aligned with the center line of the ear hole of the pry block lifting ear 10; along the thickness direction of the pry block lifting ear 10, the center of the tooling beam 3 is aligned with the center line of the first jack 1 and the second jack 2; preferably, the tooling beam 3 in this embodiment is an I-section structural beam, and can also be a U-shaped channel steel.

[0039] Two limiting devices are arranged below the tooling beam 3, namely the first limiting device 4 and the second limiting device 5, which are used to limit the relative movement of the first jack 1 and the second jack 2 and the tooling beam 3 to ensure stability; wherein, the first limiting device 4 and the second limiting device 5 are both circular sleeves, and the pistons of the first jack 1 and the second jack 2 are placed in the circular sleeves of the first limiting device 4 and the second limiting device 5, and the first limiting device 4 and the second limiting device 5 and the tooling beam 3 are fixedly connected in this embodiment, for example, by welding.

[0040] The number of the tooling lifting lug 6 is 1, which is placed on the lower surface of the tooling beam 3 and aligned with the center line of the tooling beam 3 and the lifting lug hole of the skid lifting lug 10;

[0041] The number of the above-mentioned shackles is 2, namely, a first shackle 7 and a second shackle 9. The first shackle 7 is connected to the tooling lifting lug 6, and the second shackle 9 is connected to the pry block lifting lug 10. The pins of the first shackle 7 and the second shackle 9 are fixed through the lifting lug holes.

[0042] The number of the electronic scale 8 is 1, which is used to display the tension value during the load test, and is connected with the first shackle 7 and the second shackle 9 to ensure that the load test value meets the project specification requirements.

[0043] The specific test method of the above device is as follows:

[0044] (1) Place the welded skid main frame beam 11 on the ground, and place the first jack 1 and the second jack 2 symmetrically according to the positions of the first limit device 4 and the second limit device 5 of the tooling beam 3 and the skid lifting lug 10.

[0045] (2) The tooling beam 3 is placed directly above the two jacks, and the piston tops of the first jack 1 and the second jack 2 are inserted into the cylinders of the first limit device 4 and the second limit device 5.

[0046] (3) The tooling lifting lug 6 on the tooling crossbeam 3 is connected through the first shackle 7, the second shackle 9, the electronic scale 8 and the pry block lifting lug 10, wherein the tooling lifting lug 6 is connected to the tooling crossbeam 3 by welding.

[0047] (4) After the preparation work is completed, the operating rods of the first jack 1 and the second jack 2 are pressed downward to move their pistons upward. The pistons will drive the tooling beam 3 to move upward, thereby generating a pulling force on the lifting lug 10 of the pry block.

[0048] (5) When the pulling force reaches the required value of the load test, the pressure is stopped, thereby realizing the application of the load to the lifting lug 10 of the skid.

[0049] (6) When the load test is completed, reset the jack to complete the load test.

[0050] Compared with conventional load test methods, the lug load test device provided in this embodiment is convenient for testing, does not require the preparation of a crane or a crane, and a counterweight, greatly reduces the work intensity, and no longer requires coordination and communication from all parties. The load test can be carried out at any time, which is simple and fast, shortens the test time, and is conducive to saving costs and construction period. The load test device occupies a small space, has simple steps, is easy to operate and observe test values, and reduces the risk of high-altitude operations.

[0051] Example 2

[0052] like Figure 2 , Figure 3 , Figure 4 As shown, this embodiment discloses another skid-mounted lifting eye load test device, which is different from the skid-mounted lifting eye load test device in Example 1 mainly in that the tooling lifting eye 6 and the tooling crossbeam 3 in this embodiment are slidable, while in Example 1 they are fixedly connected, as follows:

[0053] In this embodiment, the I-shaped tooling crossbeam 3 is rotated 90°, that is, the tooling crossbeam 3 is H-shaped, and a sliding groove 19 of a certain length is opened on the middle web of the tooling crossbeam 3, and a plurality of groups of limit holes 14 are arranged at equal intervals on both sides of the sliding groove 19. Correspondingly, a rectangular groove is arranged on the tooling lifting ear 6, and the limit plate 13 can pass through the rectangular groove. A through hole is respectively opened on the limit plate 13 on both sides of the tooling lifting ear 6. After the tooling lifting ear 6 is inserted into the sliding groove 19 from the bottom of the tooling crossbeam 3 upward, the limit plate 13 is inserted into the rectangular groove of the tooling lifting ear 6. The limit plate 13 and the tooling lifting ear 6 are perpendicular to each other and form a cross shape. The tooling lifting ear 6 is moved downward until the limit plate 13 contacts the web of the tooling crossbeam 3, and then the limit bolt 12 is used to pass through the through hole of the limit plate 13 and the limit hole 14 of the tooling crossbeam 3 to fix the position of the tooling lifting ear 6.

[0054] In this embodiment, the position of the tooling lifting lug 6 can be adjusted by providing a sliding groove 19 on the tooling crossbeam 3. After the position of the tooling lifting lug 6 is adjusted, the limiting bolt 12 is passed through the through hole of the limiting plate 13 and the limiting hole 14 of the tooling crossbeam 3 to fix the position of the tooling lifting lug 6. This form can not only adjust the position of the tooling lifting lug 6, but also change the specification and size of the tooling lifting lug 6 plate according to the size of the load required for the test, and also realize the replacement of the specifications of the shackle.

[0055] Example 3

[0056] like Figure 5 , Figure 6 As shown, this embodiment also discloses another skid-mounted lifting ear load test device, which is different from the skid-mounted lifting ear load test device in Example 2 mainly in that: the tooling beam 3 is an I-shaped, the tooling lifting ear 6 is designed to be hung on the lower flange of the tooling beam 3, and an inverted T-shaped slot is set on the tooling lifting ear 6. The tooling lifting ear 6 is provided with a limit plate 15 along the length direction of the tooling beam 3. The limit plates 15 are respectively located on both sides of the tooling lifting ear 6, and there are 4 limit plates 15 in total. Each limit plate 15 is provided with a through hole, and the lower flange of the tooling beam 3 needs to be provided with a through hole 16 with an equal spacing with the limit plate. The tooling lifting ear 6 is inserted into the lower flange from one side of the tooling beam 3 to adjust the position of the tooling lifting ear 6. After confirming the position, the limit plate 15 and the tooling beam 3 are fixed with the limit bolt 12, thereby playing a limiting role.

[0057] The connection method between the tooling crossbeam 3 and the tooling lifting lug 6 in this embodiment can be replaced by the connection method in Embodiment 2 in an equivalent manner.

[0058] Example 4

[0059] This embodiment also discloses another skid-mounted lifting eye load test device, which is different from Embodiment 1, Embodiment 2, and Embodiment 3 mainly in that: in this embodiment, the position limiting device can move on the tooling beam 3 and can complete the self-locking fixed position. In Embodiment 1, Embodiment 2, and Embodiment 3, the position limiting device is fixedly connected to the tooling beam 3, for example, by welding.

[0060] Specifically, Figure 7 As shown, this embodiment takes the first limit device 4 as an example for explanation. In this embodiment, the first limit device 4 is similar to a bucket shape, including a top plate 4-2 and a cylindrical side plate 4-3. A through hole 4-1 is set in the middle of the top plate 4-2, and a limit device slideway is set on the tooling crossbeam 3. Bolts pass through the through hole of the limit device and the limit device slideway on the tooling crossbeam 3, and are fixed with nuts. Through the limit device slideway, the limit device can be controlled to keep the center line aligned with the lifting ear.

[0061] In order to make the jack more firmly supported on the bottom surface of the limit device, a groove is arranged on the piston end surface of the jack, the inner diameter of the groove is larger than the head diameter of the bolt, and the depth of the groove is larger than the height of the bolt head.

[0062] Example 5

[0063] This embodiment also discloses another skid-mounted lifting eye load test device, which differs from the embodiment 4 mainly in that the top plate 4-2 of the limiter is designed to be a magnetic material, so that the position of the limiter can be flexibly adjusted. Similarly, the end of the tooling lifting eye 6 close to the tooling crossbeam 3 can also be made of a magnetic material, so that the position of the tooling lifting eye 6 can be flexibly adjusted.

[0064] It should be noted that the limiting device disclosed in this embodiment can be applied to Embodiment 1, Embodiment 3 and Embodiment 6, and can be combined with any of Embodiments 1 to 3, and Embodiment 6.

[0065] Example 6

[0066] like Figure 8 As shown, this embodiment also discloses another skid-mounted lifting ear load test device, which is different from Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, and Embodiment 5 mainly in that: in order to more accurately set the skid lifting ear 10 at the center of the two jacks, a position caliper 18 can be set, and the buckles 17 slidably set at both ends of the caliper 18 are set on the side walls of the first jack 1 and the second jack 2. The scale in the middle of the position caliper is 0, and the scale gradually increases from the middle to the two ends. Correspondingly, a caliper buckle is set on the side wall of the jack to support and fix the position caliper.

[0067] It should be noted that the caliper setting disclosed in this embodiment can be applied to embodiments 1 to 5, and can be combined with any of embodiments 1 to 5.

[0068] Finally, it should be noted that relational terms such as first and second are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any actual relationship or order between these entities or operations.
