DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7The present invention provides a technical solution: a strength detection device for processing a distribution cabinet, comprising a bottom plate 1, a support rod 2, a top plate 3 and a distribution cabinet body 5, wherein one end of the support rod 2 is fixed on the bottom plate 1, and the other end of the support rod 2 is fixed on the top plate 3, and the distribution cabinet body 5 is placed at the notch position on the bottom plate 1, and a first impact mechanism 6 is arranged below the top plate 3, and the first impact mechanism 6 and the second impact mechanism 7 are connected to each other, and the first impact mechanism 6 comprises a mounting plate 601, a counterweight block 602, a first impact block 603, a sliding rod 604 and a second spring 605, and a counterweight block 602 is fixed symmetrically on the lower end surface of the mounting plate 601, and a first impact block 603 is arranged below the mounting plate 601, and a sliding rod 604 is fixed on the first impact block 603, and the sliding rod 604 and the mounting plate 601 are slidably connected, and a second spring 605 is fixed between the first impact block 603 and the mounting plate 601, and the mounting plate 601 is connected with a traction mechanism 8, and the second impact mechanism 7 comprises a movable plate 701, guide rod 702, connecting rod 703, vertical rod 704, adjustment plate 705, bidirectional threaded rod 706, first threaded rod 707, second impact block 708 and scale rod 709, the movable plate 701 and the guide rod 702 are slidably connected, the guide rod 702 is fixed on the top plate 3, one end of the connecting rod 703 is rotatably connected to the movable plate 701, and the other end of the connecting rod 703 is rotatably connected to the mounting plate 601, and an adjustment plate 705 is arranged on the lower side of the movable plate 701. 05. The adjustment plate 705 is connected to the first threaded rod 707 through a thread. The first threaded rod 707 is connected to the second impact block 708 through a bearing. The position of the second impact block 708 is adjusted by the first threaded rod 707. The gravity of the counterweight block 602 and the first impact block 603 is used to detect the upper end surface of the distribution cabinet body 5. The transmission action of the connecting rod 703 enables the second impact block 708 to move to perform impact detection on the side of the distribution cabinet body 5.

[0029] A limit mechanism 4 is installed on the bottom plate 1, and the limit mechanism 4 includes a clamping plate 401, a ball 402, a cross bar 403, a fixed plate 404 and a first spring 405. The clamping plate 401 is arranged above the bottom plate 1, and the front end of the clamping plate 401 is a slope structure, and the balls 402 are installed on the clamping plate 401 at equal intervals, and the balls 402 can roll when in contact with the power distribution cabinet body 5; the clamping plate 401 is fixed with a cross bar 403, and the cross bar 403 and the fixed plate 404 are slidably connected, and the fixed plate 404 is fixed on the bottom plate 1; one end of the first spring 405 is fixed on the clamping plate 401, and the other end of the first spring 405 is fixed on the fixed plate 404;

[0030] When using the strength detection device for power distribution cabinet processing, if Figure 1-Figure 7As shown, first, the distribution cabinet body 5 is pushed into the groove on the bottom plate 1 by the universal wheel at the lower end of the distribution cabinet body 5. When the distribution cabinet body 5 contacts and slides with the front inclined surface of the clamping plate 401, the clamping plate 401 is forced to move. With the rolling effect of the ball 402, the friction between the distribution cabinet body 5 and the clamping plate 401 can be reduced, which facilitates the movement of the distribution cabinet body 5. With the sliding guide effect between the cross bar 403 and the fixed plate 404, the stability of the movement of the clamping plate 401 can be ensured. At this time, the first spring 405 is forced to shrink until the distribution cabinet body 5 moves to the bottom of the first impact block 603. At this time, the first spring 405 provides a force to achieve the limiting effect of the distribution cabinet body 5.

[0031] Vertical rods 704 are fixed symmetrically on the movable plate 701, and the vertical rods 704 are slidably connected to the adjustment plate 705, and the adjustment plate 705 and the movable plate 701 are connected to the bidirectional threaded rod 706 through threads; a scale rod 709 is fixed on the second impact block 708, and the scale rod 709 is slidably connected to the adjustment plate 705;

[0032] After the power distribution cabinet body 5 is installed, Figure 1-Figure 7 As shown, at this time, the first impact block 603 is located at the uppermost side, and the arc-surface protrusion 801 is snap-fitted with the card plate 802. Then, the position of the second impact block 708 is adjusted according to the width of the power distribution cabinet body 5. By rotating the bidirectional threaded rod 706, in conjunction with the threaded connection between the bidirectional threaded rod 706, the adjustment plate 705 and the movable plate 701, the distance between the adjustment plate 705 and the movable plate 701 can be adjusted, thereby adjusting the height of the second impact block 708. Then, by the threaded connection between the first threaded rod 707 and the adjustment plate 705, the left and right position of the second impact block 708 can be adjusted. In conjunction with the sliding action between the scale rod 709 and the adjustment plate 705, the stability of the movement of the second impact block 708 can be ensured. In conjunction with the scale on the scale rod 709, the position of the second impact block 708 can be determined, ensuring that the second impact block 708 can contact the power distribution cabinet body 5 to achieve an impact during the later detection process.

[0033] The traction mechanism 8 includes an arc-surface convex block 801, a clamping plate 802, a mounting block 803, an inclined surface block 804 and a hydraulic rod 805. The arc-surface convex block 801 is fixed to the upper end surface of the mounting plate 601, and the arc-surface convex block 801 and the clamping plate 802 are in a clamping connection; the clamping plate 802 and the mounting block 803 are in a rotational connection, and a torsion spring is also connected between the clamping plate 802 and the mounting block 803; the clamping plate 802 and the inclined surface block 804 are in a sliding connection, and the inclined surface block 804 is fixed on the top plate 3, and the inclined surface block 804 and the clamping plate 802 are distributed in a one-to-one correspondence; the mounting block 803 is fixed to the output end of the hydraulic rod 805, and the hydraulic rod 805 is fixed on the top plate 3;

[0034] After the device adjustment is completed, Figure 1-Figure 7 As shown, during the inspection, the hydraulic rod 805 is controlled to contract, thereby driving the arc-surface convex block 801, the clamping plate 802 and the mounting plate 601 to move upward. At this time, the clamping plate 802 contacts and slides with the inclined block 804. The sliding action between the clamping plate 802 and the inclined block 804 causes the clamping plate 802 to rotate under force. When the clamping plate 802 is separated from the arc-surface convex block 801, the locking action on the mounting plate 601 is released. At this time, under the action of the gravity of the counterweight block 602 and the first impact block 603, the first impact block 603 falls downward. When the first impact block 603 is in contact with the distribution cabinet When the main body 5 collides, the detection function of the upper end surface of the distribution cabinet main body 5 can be realized, and when the mounting plate 601 moves downward, the transmission function of the connecting rod 703 is cooperated to make the guide rod 702, the adjustment plate 705 and the second impact block 708 move. When the first impact block 603 contacts the distribution cabinet main body 5, the second impact block 708 does not contact the distribution cabinet main body 5 at this time. Under the action of the gravitational potential energy of the counterweight block 602, when the first impact block 603 contacts and collides with the distribution cabinet main body 5, the mounting plate 601 can continue to move downward a certain distance relative to the counterweight block 602. , with the transmission effect of the connecting rod 703, the second impact block 708 can contact and collide with the distribution cabinet body 5 to produce an impact effect, so that the detection effect of the side of the distribution cabinet body 5 can be realized. According to the above principle, the multi-faceted detection effect of the distribution cabinet body 5 can be realized simultaneously. The degree of deformation of the distribution cabinet body 5 after the impact can be used to determine whether the quality of the distribution cabinet body 5 is qualified. After the detection is completed, the hydraulic rod 805 is extended to drive the mounting block 803 and the card plate 802 to move downward. When the card plate 802 is separated from the inclined block 804, the card plate is caused to move downward under the action of the torsion spring. 802 returns to the vertical state. When the clamping plate 802 moves down to contact the arc-surface protrusion 801 on the mounting plate 601, the clamping plate 802 can be flipped over by the sliding action between the clamping plate 802 and the arc-surface protrusion 801 until the clamping plate 802 and the arc-surface protrusion 801 are engaged by the action of the torsion spring. Finally, the first impact mechanism 6 and the second impact mechanism 7 can be reset by contracting the hydraulic rod 805 until the upper end of the clamping plate 802 just contacts the inclined block 804 for the next detection. This is the working principle of the strength detection device for power distribution cabinet processing.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
