[0033] The present invention provides a lug eye plate load test device 100, such as Figure 1 As shown, the eye plate load test device 100 includes a first door frame 10, a second door frame 20 and a connecting rod 30 for passing the eye plate 80, and the first door frame 10 can be set on the second door frame 20. Specifically, the first door frame 10 and the second door frame 20 have the same shape, and the first door frame 10 is proportionally larger than the second door frame 20, so that the second door frame 20 can be placed inside the first door frame 10. The connecting rod 30 can be passed through each side plate of the first door frame 10 and the second door frame 20 and the eye plate 80, so that the first door frame 10, the second door frame 20 and the eye plate 80 are connected, wherein the connecting rod 30 and the first door frame 10 and the eye plate 80 can be fixedly connected, and the connecting rod 30 and the first door frame 10 can move relative to each other in a set direction within a set distance, so as to drive the first door frame 10 and the eye plate 80 to move relative to the second door frame 20 in a set direction within a set distance. An actuator 40 may be provided between the top plates of the first door frame 10 and the second door frame 20, and the actuator 40 is used to apply forces in directions away from each other to the two top plates in a set direction. When the top plate of the second door frame 20 is subjected to force, the side plate of the second door frame 20 will abut against the mounting surface 90 of the eye plate 80 of the lifting lug. When the top plate of the first door frame 10 is subjected to force, the first door frame 10 drives the connecting rod 30 to move within a set distance along a set direction to the farthest distance between the two top plates. At this time, the first door frame 10 drives the connecting rod 30 to apply tension to the eye plate 80. The actuator 40 may be connected to a power member 50, and the power member 50 can drive the actuator 40 to move.

[0034] It should be noted that the setting direction mentioned in the embodiment of the utility model refers to the direction perpendicular to the mounting surface 90 of the eye plate 80 to be tested. It can be understood that when the first door frame 10, the second door frame 20 and the eye plate 80 to be tested are connected in series, the actuator 40 applies forces in directions away from each other to the two top plates in the direction perpendicular to the mounting surface 90 of the eye plate 80 to be tested.

[0035] In summary, compared with the prior art, the eye plate load test device 100 has at least the following beneficial effects:

[0036] The eye plate load test device 100 comprises a first door frame 10, a second door frame 20 and a connecting rod 30, wherein the eye plate 80 is placed in the second door frame 20, and the connecting rod 30 is passed through each side plate of the first door frame 10 and the second door frame 20, and the eye plate 80, so that the first door frame 10, the second door frame 20 and the eye plate 80 are fixedly connected. The structure is simple, the volume is small, and the door frame suitable for the eye plate 80 can be selected according to the eye plates 80 of different sizes. The flexibility is high, the cost is low, the assembly is simple and the safety is high. High; the power component 50 drives the actuator 40 to apply forces in opposite directions to the top plates of the first door frame 10 and the second door frame 20 in the set direction, so that the second door frame 20 is against the mounting surface 90 of the lifting eye plate 80, and the first door frame 10 pulls the connecting rod 30 to apply tension to the lifting eye plate 80, and the tension on the lifting eye plate 80 is calculated by the driving value provided by the power component 50 and the effective area of ​​the actuator 40, thereby the load value of the lifting eye plate 80 can be accurately obtained.

[0037] In order to make the technical personnel in this field better understand the present utility model scheme, the following will be combined with the attached Figures 1 to 3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0038] In some embodiments, as a configuration method of the actuator 40, such as Figure 1 As shown, the fixed end of the actuator 40 can be arranged on the top plate of the second door frame 20, and the movable end of the actuator 40 can be telescopically pressed against the top plate of the first door frame 10.

[0039] Alternatively, as another arrangement of the actuator 40 , the fixed end of the actuator 40 may be disposed on the top plate of the first door frame 10 , and the movable end of the actuator 40 may be telescopically pressed against the top plate of the second door frame 20 .

[0040] It can be understood that the actuator 40 can perform telescopic movement by setting the fixed end of the actuator 40 on one of the top plates, and the movable end can adjust the force against the other top plate by telescoping to adjust the pulling force applied to the eye plate 80.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, the first door frame 10 includes a first top plate 11 and two first side plates 12. The two first side plates 12 can be arranged at both ends of the first top plate 11. The actuator 40 can be arranged on the side of the first top plate 11 facing the connecting rod 30. The first side plate 12 can be provided with a fixing hole 121 for the connecting rod 30 to pass through. When it is necessary to perform a load test on the lifting ear eye plate 80, the lifting ear eye plate 80 can be placed between the two first side plates 12, and the fixing holes 121 of the two first side plates 12 are arranged concentrically with the hole positions of the lifting ear eye plate 80. When the connecting rod 30 is passed through the fixing holes 121 on the two first side plates 12 and the lifting ear eye plate 80, the first door frame 10, the lifting ear eye plate 80 and the connecting rod 30 are fixedly connected.

[0042] In some embodiments, the first top plate 11 and the first side plates 12 may both be steel plates, and the first top plate 11 and the two first side plates 12 may be fixed by welding to enhance the force-bearing performance of the first door frame 10 .

[0043] In some embodiments, Figure 1 and Figure 3 As shown, the second door frame 20 includes a second top plate 21 and two second side plates 22, the two second side plates 22 can be arranged at both ends of the second top plate 21, the actuator 40 can be arranged on the side of the second top plate 21 facing away from the connecting rod 30, and a waist-shaped hole 221 can be opened on the second side plate 22, and the waist-shaped hole 221 can be used for the connecting rod 30 to pass through and enable the connecting rod 30 to move a set distance along a set direction. It can be understood that the distance between the two ends of the waist-shaped hole 221 is the set distance that the connecting rod 30 can move along the set direction.

[0044] In some embodiments, the second top plate 21 and the second side plates 22 may both be steel plates, and the second top plate 21 and the two second side plates 22 may be fixed by welding to enhance the force-bearing performance of the second door frame 20 .

[0045] In some embodiments, Figure 1 and Figure 3 As shown, the distance between the side of the second top plate 21 facing the connecting rod 30 and the end of the second side plate 22 away from the second top plate 21 can be greater than the length of the hanging ear eye plate 80, so that when the hanging ear eye plate 80 is placed between the two second side plates 22, the second side plate 22 can contact the mounting surface 90 of the hanging ear eye plate 80.

[0046] In some embodiments, Figure 1 As shown, the actuator 40 and the power member 50 may be connected via a connecting pipe 60, and the power member 50 may provide driving force to the actuator 40 via the connecting pipe 60. The connecting pipe 60 may be a hydraulic oil pipe.

[0047] In some embodiments, the actuator 40 may be a hydraulic oil jack, and the effective area of ​​the oil cylinder of the hydraulic oil jack is the effective area required to calculate the magnitude of the pulling force on the eye plate 80 .

[0048] In some embodiments, the power member 50 may be a hydraulic pump, specifically a hydraulic manual pump, and the oil pressure of the hydraulic pump is the driving value required to calculate the pulling force on the eye plate 80 .

[0049] In some embodiments, Figure 1 As shown, the power member 50 may be provided with a pressure gauge 51, so as to intuitively obtain the driving value provided by the power member 50 through the pressure gauge 51. Specifically in this embodiment, the pressure gauge 51 can intuitively reflect the oil pressure value of the hydraulic pump.

[0050] In some embodiments, the connecting rod 30 may be an alloy steel shaft, specifically a high-strength alloy steel shaft.

[0051] Specifically in this embodiment, the working principle of the eye plate load test device 100 is as follows:

[0052] First, buckle the second door frame 20 onto the eye plate 80 that needs to be inspected, so that the ends of the two second side panels 22 are in contact with the mounting surface 90 of the eye plate 80; buckle the first door frame 10 onto the second door frame 20, and then pass the connecting rod 30 through the two first side panels 12, the two second side panels 22 and the eye plate 80, that is, string the first door frame 10, the second door frame 20 and the eye plate 80 together.

[0053] A hydraulic oil top is arranged between the first top plate 11 and the second top plate 21, and the fixed end of the hydraulic oil top is arranged on the second top plate 21. The hydraulic oil top is connected to the hydraulic pump through a hydraulic hose; check whether the hydraulic pump, the hydraulic oil top, the hydraulic oil pipe, the joint 70 and the pressure gauge 51 are in normal and reliable condition. When the hydraulic pump pumps hydraulic oil into the hydraulic oil top, the plunger (i.e., the movable end) of the hydraulic oil top extends out and abuts against the first top plate 11, and the force of the first mast 10 is transmitted to the alloy steel shaft and the eye plate 80.

[0054] Increase the oil pressure slowly, and observe whether the hydraulic pump, hydraulic oil top, hydraulic oil pipe, joint 70, pressure gauge 51 and alloy steel shaft are normal and reliable.

[0055] The thrust of the hydraulic oil top on the first mast 10 is calculated based on the oil pressure displayed on the pressure gauge 51 and the effective area of ​​the hydraulic oil top. According to the force balance, it can be known that the thrust is the tension on the eye plate 80.

[0056] After the load condition of the lifting eye plate 80 is detected, the hydraulic pump is slowly depressurized, and after the lifting eye plate load test device 100 is removed, the welding part of the lifting eye plate 80 is checked again to see if it is intact and deformed.

[0057] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of the claims of the utility model.
