Description

Technical Field

[0001] The invention relates to a docking device, in particular to a water cooling cover docking device for a hot test bench, and belongs to the technical field of hot test bench experiments. Background Art

[0002] In the field of water-cooling hood docking technology for hot test benches, with the continuous growth in the demand for related product testing, the demand for efficient, convenient and economical water-cooling hood docking devices has become increasingly urgent.

[0003] At present, similar products on the market generally use a vehicle-mounted frame structure device when docking the water-cooling cover of the hot test bench. This structure mainly fixes the water-cooling cover on the vehicle-mounted device, and then carries out docking and subsequent test operations. However, in the docking process, in order to ensure the safe and stable operation of the device, this traditional vehicle-mounted water-cooling cover installation device must be counterweighted. This counterweight link directly leads to a significant increase in the overall footprint of the device. Under the condition of limited site resources, it greatly limits the flexibility of the test layout. At the same time, the operation process of the traditional vehicle-mounted water-cooling cover installation device is extremely cumbersome, requiring a lot of manpower and time costs, which seriously affects the test efficiency. Due to the complexity of the vehicle-mounted frame structure and the counterweight system, the cost of the vehicle-mounted frame structure device remains high. Taking these factors into consideration, the existing technology is difficult to meet the growing requirements of batch testing and cannot adapt to the needs of modern industrial production for efficient and low-cost testing. Therefore, a new type of water-cooling cover docking device is needed to overcome these problems and promote technological progress and development in related fields. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0027] Example 1, reference Figure 1-8 To illustrate the present embodiment, a hot test bench water cooling cover docking device includes a suspension beam 1, a suspension belt 2, a docking sling 3, a sling seat 4, an auxiliary bracket 5, and a fixing structure 7;

[0028] The lifting beam 1 is placed parallel to the docking sling 3 and connected by a sling 2;

[0029] The docking hanger 3 is installed on the hanger seat 4, and the hanger seat 4 is installed on the auxiliary bracket 5. A trapezoidal placement cavity is opened on the front end surface of the hanger seat 4, and the water cooling cover 6 is placed in the trapezoidal placement cavity and is connected to the hanger seat 4 through a fixing structure 7.

[0030] Furthermore, the suspension beam 1 and the docking sling 3 are both channel steel structures; the groove of the suspension beam 1 is arranged upward, and two first lifting rings are symmetrically provided at the bottom of the groove, and second lifting rings are provided at the left and right ends of the bottom surface of the suspension beam 1; the groove of the docking sling 3 is also arranged upward, and two third lifting rings are symmetrically provided at the bottom of the groove, and the second lifting ring and the third lifting ring are connected by a sling 2.

[0031] Furthermore, the docking hanger 3 is a two-section split structure.

[0032] Furthermore, a rubber pad is attached to the inner side of the trapezoidal placement cavity of the sling seat 4 , in order to increase the friction between the water cooling cover 6 and the sling seat 4 .

[0033] Furthermore, the fixing structure 7 includes a fixing block 12, a fixing bolt 8, a disassembly plate 9, a fastening screw 10, and a disassembly screw 11. The fixing block 12 is installed on the hanger seat 4. When fixing the water-cooling cover 6, the inner end of the fixing bolt 8 passes through the disassembly plate 9 and the fixing block 12 from the outside to the inside in sequence, and is connected to the docking hole of the water-cooling cover 6. The fastening screw 10 is screwed into the fixing block 12 perpendicular to the fixing bolt 8, and the fixing bolt 8 is tightened; when disassembling the water-cooling cover 6, the fastening screw 10 is loosened, and the disassembly screw 11 is screwed into the disassembly plate 9 and the fixing block 12 parallel to the fixing bolt 8 until the inner end of the fixing bolt 8 is separated from the docking hole of the water-cooling cover 6.

[0034] Furthermore, the sling 2 is connected to the sling beam 1 and the sling rings on the docking sling 3 through a horseshoe buckle.

[0035] Furthermore, the materials of the hanging beam 1, the docking hanger 3, the hanger seat 4 and the auxiliary bracket 5 are all Q235 materials, with an elastic modulus (E=σ / ε) of 2.06E11Pa, a Poisson's ratio (ν=-ε1 / ε) of 0.3, and a yield strength of 235MPa.

[0036] Furthermore, the grooves of the suspension beam 1 and the docking sling 3 are evenly distributed with reinforced cross beam structures.

[0037] Furthermore, in order to ensure the overall stability of the device during lifting, the finite element analysis software ANSYS Workbench 19.2 was used to perform strength analysis on the lifting beam 1, the docking hanger 3, the hanger seat 4 and the auxiliary bracket 5. The main structure is made of Q235 material, with an elastic modulus (E = σ / ε) of 2.06E11Pa, a Poisson's ratio (ν = -ε1 / ε) of 0.3, and a yield strength of 235MPa;

[0038] Divide the mesh of the hanging beam 1, apply the load, and apply a total of 2600N of tension to the hanging points on both sides of the hanging beam 1; Figure 5 The maximum stress is 97.89MPa, the maximum displacement is 0.60mm, and the maximum stress is much smaller than the yield strength of the material 235MPa. Therefore, the design strength of the suspension beam 1 meets the requirements;

[0039] After the butt spreader 3 and the spreader seat 4 are fixed, the whole is gridded, a load is applied, and a pressure of 2000N is applied to the fixing bolt 8; Figure 6 and Figure 7The maximum stress is 93.85 MPa, the maximum displacement is 4.36 mm, and the maximum stress is much smaller than the yield strength of the material 235 MPa. Therefore, after the butt-jointed sling 3 and the sling seat 4 are fixed, the overall design strength meets the requirements.

[0040] The auxiliary bracket 5 is meshed, and a load is applied to the top surface of the auxiliary bracket 5, and a total pressure of 2600N is applied; Figure 8 The maximum stress is 64.83 MPa, the maximum displacement is 0.11 mm, and the maximum stress is much smaller than the yield strength of the material, 235 MPa. Therefore, the design strength of the auxiliary bracket 5 meets the requirements.

[0041] The present invention can solve the practical problems of the existing water-cooling cover docking device, such as large floor space, heavy operation, high cost and inability to conduct batch tests; the device has a simple structure, makes the operation process of disassembling, docking and assembling the water-cooling cover convenient and fast, and improves the docking efficiency;

[0042] The present invention can realize horizontal lifting of the water cooling cover, avoiding the leveling process of the vehicle-mounted water cooling device during docking assembly due to uneven ground or the accuracy of vehicle-mounted tooling; at the same time, the lifting method is adopted, and the operator only needs to operate the crane during the lifting process, avoiding the risk of bumping and smashing.
