[0026] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments.

[0027] See also Figure 1-6 The radar base 500 loading test fixture of the utility model can be used to perform a loading test on the radar, so as to simulate whether the radar meets the requirements when operating under the influence of environmental wind force.

[0028] like Figure 1 As shown, the radar base 500 loading test tooling includes: a loading unit 100, a test unit 200 and a pull rope 300, wherein the loading unit 100 is provided with a support frame 101, and the support frame 101 is provided with a pulley assembly 109, as shown in FIG. Figure 3As shown, the fixed pulley 112 part 110 of the pulley assembly 109 is arranged on the upper part of the support frame 101, as shown in FIG. Figure 4 As shown, the movable pulley 115 part 113 of the pulley assembly 109 is arranged directly below the fixed pulley 112 part 110, and a counterweight device 116 is arranged below the movable pulley 115 part 113, and the counterweight device 116 is connected to the movable pulley 115 part 113; the test unit 200 includes a mounting seat 201 and a winch 202, and the mounting seat 201 is used to install the radar base 500, as shown in FIG. Figure 5 A connection seat 206 for connecting to the radar base 500 is provided on the winch 202, and winding grooves 207 are continuously provided on the outer peripheral side of the winch 202; one end of the pull rope 300 is relatively fixed to the fixed pulley 112 part 110, and the other end is extended after passing through the movable pulley 115 part 113 and the fixed pulley 112 part 110 and is fixed in the winding groove 207.

[0029] like Figure 1 As shown, when the radar base 500 loading test tool is used, the radar base 500 to be tested is mounted on the mounting base 201, and the radar base 500 is connected by the connecting base 206 to set the winch 202 on the radar base 500; then the end of the pull rope 300 of the loading unit 100 is connected to the winding groove 207; after completion, the radar base 500 starts to work, and the rotation of the radar base 500 during the operation of the radar base 500 will drive the winch 202 to rotate, and the pull rope 300 will be reeled in or released during the rotation of the winch 202. Since the other end of the pull rope 300 is connected to the counterweight device 116, the tension applied by the counterweight device 116 cooperates with the winch 202 to reel in and release the pull rope 300 to simulate the on-site application environment required for the test of the radar base 500.

[0030] like Figure 1 As shown, the radar base 500 loading test tooling also includes a support base 400, and a plurality of feet 401 are arranged at the bottom of the support base 400. A support frame 101 is fixedly arranged at one end of the upper side of the support base 400, and a mounting base 201 is fixedly arranged at the other end. The mounting base 201 and the support frame 101 are relatively integrated by the support base 400. Firstly, it is convenient for the test installation during application, so that there is a relatively fixed installation position between the mounting base 201 and the support frame 101. Secondly, it enables the tooling to have a relatively independent integrity, which is convenient for moving according to needs. Furthermore, the support height of the feet 401 is adjustable, so that the support of the feet 401 can be adjusted according to the ground after moving.

[0031] like Figure 1As shown, a low-cost but structurally stable support frame 101 design structure is provided. The support frame 101 includes three columns 102 and a mounting plate 103. The lower ends of the three columns 102 are dispersedly fixed on the support base 400, and the top ends are gathered together and fixed on the mounting plate 103.

[0032] like Figure 4 As shown, in order to facilitate the adjustment of the tension applied by the end of the counterweight device 116 to the pull rope 300 according to needs, the counterweight device 116 includes a storage basket 117, in which a counterweight block 118 is placed. The storage basket 117 is suspended on the movable pulley 115 part 113. The control of the tension of the pull rope 300 can be controlled by the weight change and mass change of the counterweight block 118.

[0033] like Figure 1 and 4 As shown, the setting of the pulley assembly 109 is mainly to solve the problem that the rotation of the winch 202 during the test will consume the space limitation problem of the up and down movement of the counterweight device 116 end. Through the setting of the pulley assembly 109, the moving speed of the pull rope 300 in the winch 202 is several times that of the moving speed of the pull rope 300 at the counterweight end, which is beneficial to reduce the actual height of the support frame 101.

[0034] Generally, if Figure 4 As shown, the pulley assembly 109 is a 1:4 pulley group, the fixed pulley 112 part 110 includes a bracket 111 fixed on the support frame 101, and the bracket 111 is provided with two fixed pulleys 112; the movable pulley 115 part 113 includes a bracket 2 114, the bracket 2 114 is connected to the counterweight device 116, and the bracket 2 114 is provided with two movable pulleys 115; one end of the pull rope 300 is fixed on the bracket 111 or on the support frame 101.

[0035] like Figure 1 and Figure 2 As shown, a guide pulley 104 is provided on the support frame 101, and the guide pulley 104 is provided on the bracket 3 105, and the bracket 3 105 is movably connected to the support frame 101; the pull rope 300 connected to one end of the winch 202 is wound around the guide pulley 104 and then extends to the winding groove 207. The pull rope 300 is guided by the guide wheel to extend into the winding groove 207 in parallel with the winding groove 207.

[0036] Among them, the bracket three 105 can be connected to the support frame 101 through a flexible rope.

[0037] In some embodiments, Figure 4As shown, a cross bar 106 is provided on the support frame 101, and then a first hinge seat 107 is hinged on the cross bar 106, and then a rotatable second hinge seat 108 is provided on the first hinge seat 107, and the second hinge seat 108 is hinged to the bracket three 105, thereby realizing the movable setting of the guide pulley 104, so that the guide pulley 104 can realize the ability of adaptively changing posture under the influence of the tension of the pull rope 300.

[0038] like Figure 5 and Figure 6 As shown, in order to solve the problem of convenience in setting the winch 202 on the radar base 500, the winch 202 includes two symmetrically arranged support parts 203, each support part 203 is respectively provided with a connecting seat 206, and a single winding groove 204 is continuously arranged 180° around the outer side of the support part 203, and the single winding grooves 204 on the two support parts 203 are spliced ​​to form a winding groove 207.

[0039] Furthermore, a connecting plate 208 is provided at the joint of the two winding single slots 204, through holes 209 are provided at both ends of the connecting plate 208, and threaded holes 205 are provided on the outer sides of the two end directions of the winding single slots 204. After the two winding single slots 204 are spliced ​​together, the two ends of the connecting plate 208 are respectively overlapped on the outer sides of the ends of the two winding single slots 204, and screws are provided to pass through the through holes 209 and then be threadedly connected with the threaded holes 205, so that the reliability of the joint of the winding single slots 204 is ensured by the connecting plate 208.

[0040] Furthermore, the outer circumference of the winch 202 is polygonal, and for the convenience of processing and manufacturing, the winding single groove 204 is octagonal after being assembled. The advantage is that the pull rope 300 will be subjected to a variable external force at the corner of the polygonal winding groove 207, which can better reflect the force fluctuation effect during wind resistance, which is conducive to the verification of the test results.

[0041] In some embodiments, Figure 5 As shown, the loading test fixture of the radar base 500 also includes an extension arm 119, one end of the extension arm 119 is fixed on the radar base 500, and the other end extends in a direction away from the radar base 500, and a load (generally set to 40KG) is set at the end away from the radar base 500, thereby simulating the deflection force received by the radar base 500 during operation.

[0042] One of the test methods:

[0043] 1) Add a counterweight 118 to the storage basket 117, and generate a 1 / 4 counterweight 118 pulling force at the end rope in the direction of the winch 202 through a 1:4 pulley set to simulate the horizontal torque generated on the radar base 500. When the horizontal pulling force of the pull rope 300 is 60KG (the counterweight is about 270KG, of which the friction force is about 30KG), it is equivalent to a horizontal wind force of level 8;

[0044] 2) When the counterweight on the loading extension arm 119 (the end is 1.5M away from the radar base 500) is 40KG, the radar base 500 is simulated to be affected by a force 8 wind bending moment;

[0045] 3) Load from low to high, once every 10KG;

[0046] 4) The radar base 500 rotates 370 degrees clockwise and then 370 degrees counterclockwise, and repeats the process;

[0047] 5) When the radar base 500 reciprocates, the position of the storage basket 117 moves from the lowest point to the highest point, and then drops from the highest point to the lowest point, also in a reciprocating cycle;

[0048] 6) The loading fixture is an octagon, simulating the rotation of a circular ring. The eight corners form eight pull ropes with a tensile force of 300, which is beneficial to the impact test effect.

[0049] 7) After running for a certain number of hours at the maximum load, check the deformation or damage of the radar base 500 structure and reducer, and use the test accuracy and other data to comprehensively evaluate the degree to which the radar base 500 is affected by wind.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
