DETAILED DESCRIPTION

[0032] The present application is described in detail below in conjunction with the accompanying drawings and specific examples, but is not limited to the examples.

[0033] Example 1

[0034] A performance detection device of heavy-duty shelf crossbeam, as shown in Figure 1 and Figure 2 , comprising a base 1, lifting blocks 2, a pressing mechanism 4 and a striking mechanism 5, the number of lifting blocks 2 is two, two lifting blocks 2 are respectively connected to the upper left and right sides of the base 1, the rear upper part of the base 1 is provided with a pressing mechanism 4 for pressing the crossbeam 3 downward, the upper part of the pressing mechanism 4 is provided with a striking mechanism 5 for striking the crossbeam 3.

[0035] As shown in Figure 1 and Figure 3 , the pressing mechanism 4 comprises a first sliding rail 41, a rotating handle 42, a first sliding block 43, a threaded rod 44, an electric push rod 45 and a pressing block 46, the first sliding rail 41 is connected to the rear upper part of the base 1, the threaded rod 44 is rotatably connected between the left and right sides of the front upper part of the first sliding rail 41, the right side of the threaded rod 44 passes out of the first sliding rail 41, the right side of the threaded rod 44 is connected with the rotating handle 42, the first sliding block 43 is threadedly connected on the threaded rod 44, the first sliding block 43 is slidably connected with the first sliding rail 41, the lower left part of the first sliding block 43 is connected with the electric push rod 45, the lower part of the telescopic rod of the electric push rod 45 is connected with the pressing block 46.

[0036] As shown in Figure 1 , Figure 4 and Figure 5 , the striking mechanism 5 comprises a fixed block 51, a pull rope 52, a counterweight 53, a rotating piece 54, a first locking piece 55 and a second sliding rail 56, the number of fixed blocks 51 is two, two fixed blocks 51 are respectively connected to the front and rear sides of the right lower part of the first sliding block 43, the rotating piece 54 is rotatably connected between the fixed blocks 51, the pull rope 52 is wound on the rotating piece 54, the pull rope 52 is located between the two fixed blocks 51, the counterweight 53 is connected to the lower part of the pull rope 52, the second sliding rail 56 is connected to the right rear part of the first sliding block 43, the first locking piece 55 is slidably connected on the second sliding rail 56, the first locking piece 55 is clamped and matched with the rotating piece 54.

[0037] The performance detection device of the heavy-duty shelf cross beam is used for detecting the strength performance of the cross beam 3 of the heavy-duty shelf. In use, the cross beam 3 needs to be placed between the upper portions of the two lifting blocks 2, then a person can hold the rotating handle 42 with hand and rotate the rotating handle 42 with hand, so that the rotating handle 42 drives the threaded rod 44 to rotate. By rotating the rotating handle 42, it is convenient for a person to rotate the threaded rod 44. Under the driving of the threaded rod 44, the first sliding block 43 can move left and right. Then the first sliding block 43 drives the electric push rod 45 and the pressing block 46 to move left and right, so that the position pressed by the pressing block 46 can be adjusted. After adjustment, the electric push rod 45 is started, and the telescopic rod of the electric push rod 45 is controlled to be elongated downward. Then the telescopic rod of the electric push rod 45 drives the pressing block 46 to move downward. After the pressing block 46 contacts the cross beam 3, the cross beam 3 is pressed downward, so that the length of the telescopic rod of the electric push rod 45 elongated downward is a standard value. Then the change of the cross beam 3 is observed. If the cross beam 3 is not damaged, it represents that the strength performance of the cross beam 3 at this position is good. If the cross beam 3 is damaged, it represents that the strength performance of the cross beam 3 is poor. A person can also control the telescopic rod of the electric push rod 45 to be shortened upward to reset, so that the pressing block 46 moves upward to reset. Then the electric push rod 45 is turned off. The first sliding block 43 is moved left and right according to the steps described in the foregoing text, so that the position of the electric push rod 45 and the pressing block 46 is changed again. Then the electric push rod 45 is started again, so that the telescopic rod of the electric push rod 45 is elongated downward again by the same length. Thus the strength performance of other positions on the cross beam 3 can be detected. The strength performance of each position on the cross beam 3 is checked by this method. In this way, the overall strength performance of the cross beam 3 can be obtained. If the strength performance of each position on the cross beam 3 is good, the overall strength performance of the cross beam 3 is good. Otherwise, the strength performance of the cross beam 3 is poor. After the pressing block 46 moves upward to reset, the first sliding block 43 can be moved left and right according to the steps described in the foregoing text again, so that the first sliding block 43 drives the fixed block 51, the pull rope 52, the counterweight 53, the rotating piece 54, the first locking piece 55 and the second sliding rail 56 to move. After the position of the first sliding block 43 is adjusted, the rotating piece 54 needs to be unlocked. Then a person needs to stably hold the position of the rotating piece 54 and move the first locking piece 55 backward with hand, so that the first locking piece 55 is separated from the rotating piece 54. Then the rotating piece 54 can be quickly rotated, so that the pull rope 52 is quickly unwound, so that the counterweight 53 can fall downward under the action of its own gravity, so that the counterweight 53 can hit the cross beam 3. In this way, the strength performance of the cross beam 3 when the cross beam 3 is hit by an article can be simulated. If the counterweight 53 does not hit the cross beam 3, it represents that the strength performance of the cross beam 3 is good. If the counterweight 53 hits the cross beam 3, it represents that the strength performance of the cross beam 3 is poor. Then the rotating piece 54 can be reversely rotated with hand, so that the pull rope 52 is wound back on the rotating piece 54, so that the counterweight 53 moves upward to reset.And people can also adjust the position of the first sliding block 43 to adjust the impact position of the counterweight 53, so as to detect the strength performance when the cross beam 3 is impacted, if the strength performance of the cross beam 3 is good, it represents that the strength performance of the cross beam 3 is good, otherwise the strength performance of the cross beam 3 is poor, after detection, the pull rope 52 is retracted on the rotating piece 54, and the first locking piece 55 is moved forward by hand to reset, so that the first locking piece 55 locks the rotating piece 54 again, and then the cross beam 3 can be taken away, the cross beam 3 is pressed by the pressing block 46 to simulate the state of the cross beam 3 normally placing articles, and the rotating piece 54 impacts the cross beam 3 to simulate the state of the cross beam 3 being impacted by articles, so that the detection result is more accurate by simulating different use states of the cross beam 3.

[0038] Embodiment 2

[0039] On the basis of embodiment 1, as shown in Figure 1 、 Figure 6 and Figure 7 , further comprising a side knocking mechanism 6, the side knocking mechanism 6 comprises a third sliding rail 61, a first extrusion piece 62, a first fixed rod 63, a knocking piece 64 and a first spring 65, the first fixed rod 63 is connected to the lower rear side of the first sliding block 43, a plurality of third sliding rails 61 are uniformly connected to the upper rear side of the base 1 from left to right, the knocking piece 64 for knocking the cross beam 3 is slidingly connected to the third sliding rail 61, the first spring 65 is connected between the rear lower side of the knocking piece 64 and the adjacent third sliding rail 61, the first extrusion piece 62 is connected to the rear upper side of the knocking piece 64, and the first extrusion piece 62 is extruded with the first fixed rod 63, the first extrusion piece 62 is extruded by the first fixed rod 63, so that the knocking piece 64 is away from the cross beam 3, and then the knocking piece 64 is moved forward to reset and knock the cross beam 3 under the action of the first spring 65.

[0040] In the initial state, the knocking piece 64 is in contact with the crossbeam 3. When the pressing block 46 and the counterweight 53 are not used, the first sliding block 43 can be moved back and forth, and the first fixed rod 63 is moved along with the first sliding block 43. Then, the first fixed rod 63 is in contact with the first pressing piece 62, and the first pressing piece 62 is moved backward under the extrusion of the first fixed rod 63. The knocking piece 64 is moved backward under the drive of the first pressing piece 62, and the first spring 65 is compressed. When the first fixed rod 63 passes the most protruding part of the first pressing piece 62, the knocking piece 64 and the first pressing piece 62 are moved forward and reset under the action of the first spring 65. Then, the knocking piece 64 knocks the side surface of the crossbeam 3. With the continuous movement of the first fixed rod 63, the first fixed rod 63 is in contact with the next first pressing piece 62, so as to repeat the above process. The first sliding block 43 is moved back and forth for a fixed number of times. Then, whether the crossbeam 3 is damaged is observed. If the crossbeam 3 is damaged, it means that the strength performance of the crossbeam 3 is poor. If the crossbeam 3 is not damaged, it means that the strength performance of the crossbeam 3 is good.

[0041] As shown in Figure 1 , Figure 8 and Figure 9 , the measuring mechanism 7 is further included. The measuring mechanism 7 includes the second pressing piece 71, the third pressing piece 72, the pigment cylinder 73, the second fixed rod 74, the second sliding block 75, the coating piece 76 and the second spring 77. The second pressing piece 71 is connected to the front part of the pressing block 46. The second fixed rod 74 is connected to the front part of the first sliding block 43. The second sliding block 75 is slidingly connected to the lower part of the second fixed rod 74. The second spring 77 is connected between the right front side of the second sliding block 75 and the right lower side of the second fixed rod 74. The pigment cylinder 73 is connected to the front part of the second sliding block 75. The pigment cylinder 73 stores pigments. The right rear side of the second sliding block 75 is connected with the third pressing piece 72. The third pressing piece 72 is in extrusion cooperation with the second pressing piece 71. The inside of the second sliding block 75 is connected with the coating piece 76. The coating piece 76 extends out of the second sliding block 75. The coating piece 76 is in communication with the pigment cylinder 73.

[0042] In order to more intuitively see whether the cross beam 3 is damaged or changed, when the cross beam 3 is placed, the cross beam 3 will be in contact with the paint piece 76, because the paint in the paint cylinder 73 will flow into the paint piece 76, so that the paint piece 76 can draw a line on the cross beam 3 later, when the pressing block 46 moves downward, the pressing block 46 drives the second extrusion piece 71 to move downward, the second extrusion piece 71 will be in contact with the third extrusion piece 72, under the extrusion of the second extrusion piece 71, the third extrusion piece 72 will move to the right, so that the third extrusion piece 72 drives the second sliding block 75, the paint cylinder 73 and the paint piece 76 to move to the right, the second spring 77 is compressed, so that the paint piece 76 draws a horizontal line on the front side of the cross beam 3, at this time the pressing block 46 has not yet contacted the cross beam 3, until the second extrusion piece 71 has passed the third extrusion piece 72, the pressing block 46 will contact the cross beam 3, at this time because the second extrusion piece 71 cannot make the third extrusion piece 72 move to the right, so it has no effect on the paint piece 76, at this time the cross beam 3 may be deformed under the pressing of the pressing block 46, but with the upward movement of the pressing block 46 to reset, this deformation may recover with the elimination of pressure, when the pressing block 46 drives the second extrusion piece 71 to move upward to the second extrusion piece 71 releases the third extrusion piece 72, under the action of the second spring 77, the second sliding block 75, the third extrusion piece 72, the paint cylinder 73 and the paint piece 76 move to the left to reset, at this time if the cross beam 3 has not been deformed, then a horizontal line will be drawn on the original horizontal line, the two lines will overlap, if the cross beam 3 is deformed, then the two lines will not completely overlap, people can more intuitively judge whether the cross beam 3 is damaged through this situation, if the two lines overlap, it means that the cross beam 3 can automatically recover after deformation, the strength performance of the cross beam 3 is good, if the two lines do not overlap, it means that the cross beam 3 cannot automatically recover after deformation, the strength performance of the cross beam 3 is poor.

[0043] As shown in Figure 1 and Figure 10 Further comprising an adjusting mechanism 8, the adjusting mechanism 8 comprises a second locking piece 81, a rotating block 82, a fixed piece 83 and a torsion spring 84, the second locking piece 81 is slidingly connected to the upper part of the pressing block 46, one fixed piece 83 is connected to the lower left front side of the pressing block 46, the other fixed piece 83 is connected to the lower right rear side of the pressing block 46, the number of rotating blocks 82 is two, the two rotating blocks 82 are respectively rotationally connected to the two fixed pieces 83, the rotating blocks 82 are in extrusion fit with the second locking piece 81, the torsion springs 84 are wound between the rotating blocks 82 and the adjacent fixed pieces 83, and the torsion springs 84 are wound on the adjacent fixed pieces 83.

[0044] In the initial state, the second locking member 81 is clamped into the rotating block 82, thereby limiting the rotating block 82, the torsion spring 84 is twisted, and the lower area of the rotating block 82 and the pressing block 46 is in the maximum state. At this time, if the pressing block 46 is allowed to move downward, the second locking member 81, the rotating block 82, the fixing member 83 and the torsion spring 84 all move downward, and the rotating block 82 will extrude the cross beam 3 downward. At this time, the cross beam 3 is in the maximum state of the pressure area, because the pressure is small when the pressure area is large, and the destruction is weak, and the pressure is large when the pressure area is small, and the destruction is strong. Therefore, if people need to reduce the pressure area, the pressing block 46 is first moved upward to reset, and the second locking member 81, the rotating block 82, the fixing member 83 and the torsion spring 84 are all moved upward to reset. Then the second locking member 81 is moved upward by hand, so that the second locking member 81 releases the rotating block 82. Under the action of the torsion spring 84, the rotating block 82 rotates, and then the rotating block 82 is located on the front and rear sides of the pressing block 46, respectively. With the downward movement of the pressing block 46, the second locking member 81, the rotating block 82, the fixing member 83 and the torsion spring 84 all move downward, but the rotating block 82 does not contact the cross beam 3 at this time, so the cross beam 3 is in the minimum state of the pressure area. In this way, the strength performance of the cross beam 3 in the most unfavorable condition can be further detected, thereby facilitating more accurate detection results. If it is necessary to make the pressure area return to the maximum state, the pressing block 46 is first moved upward to reset, so that the second locking member 81, the rotating block 82, the fixing member 83 and the torsion spring 84 are all moved upward to reset. Then the rotating block 82 is reversely rotated to reset by hand, the torsion spring 84 is twisted, the second locking member 81 is moved downward by hand, and the second locking member 81 is clamped into the rotating block 82. Therefore, the rotating block 82 is limited again, and the pressure area is again changed to the maximum state.

[0045] As shown in Figure 1 , Figure 11 and Figure 12 , the fixing mechanism 9 is further included. The fixing mechanism 9 includes the fourth sliding rail 91, the bidirectional screw rod 92, the sliding member 93, the telescopic member 94 and the third spring 95. The number of the fourth sliding rail 91 is two, and the two fourth sliding rails 91 are connected to the sides of the lifting block 2 close to each other. The number of the bidirectional screw rod 92 is two, and the two bidirectional screw rods 92 are rotationally connected to the front and rear sides between the two fourth sliding rails 91. The front and rear sides of the bidirectional screw rod 92 are threadedly connected with the sliding member 93. The sliding member 93 is slidably connected with the proximal fourth sliding rail 91. The number of the telescopic member 94 is four, and the four telescopic members 94 are slidably connected to the upper portions of the four sliding members 93. The upper portion of the telescopic member 94 and the proximal sliding member 93 are both wound with the third spring 95, and the third spring 95 is wound on the corresponding telescopic member 94.

[0046] Before placing the cross beam 3 on the lifting block 2, the bidirectional screw 92 needs to be rotated by hand to move the sliding piece 93 to the side of the mutual far away direction, so that the corresponding telescopic piece 94 and the third spring 95 also move, so that there is a large enough gap between the two adjacent sliding pieces 93 to place the cross beam 3, and then the cross beam 3 is placed on the lifting block 2, and the cross beam 3 needs to be placed between the two adjacent sliding pieces 93, and then the telescopic piece 94 is moved upward, so that the third spring 95 is stretched, and the telescopic piece 94 is kept in this state, and the bidirectional screw 92 is rotated in the opposite direction, so that the sliding piece 93 is moved to the side of the mutual close direction, so that the corresponding telescopic piece 94 and the third spring 95 also move, so that the two adjacent sliding pieces 93 can clamp the front and rear sides of the cross beam 3, and after the sliding piece 93 clamps the cross beam 3, the telescopic piece 94 is loosened, and under the action of the third spring 95, the telescopic piece 94 moves downward, so that the telescopic piece 94 can clamp the upper and lower sides of the cross beam 3 in cooperation with the lifting block 2, so that the cross beam 3 can be prevented from deviating when the cross beam 3 is detected, and when the cross beam 3 needs to be removed, the telescopic piece 94 is first moved upward by hand, so that the third spring 95 is stretched, and the telescopic piece 94 is kept in this state, the bidirectional screw 92 is rotated, so that the sliding piece 93 is moved to the side of the mutual far away direction, so that the corresponding telescopic piece 94 and the third spring 95 also move, and then the telescopic piece 94 is loosened, and under the action of the third spring 95, the telescopic piece 94 moves downward and resets, and the cross beam 3 can be removed.
