DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0023] like Figures 1 to 5 As shown, the present invention provides a hydraulic switch cabinet trolley, comprising: a base 1, a lifting plate 2, a placement plate 3 and a hydraulic cylinder 6, wherein the base 1, the lifting plate 2 and the placement plate 3 are all configured as square plates, the lifting plate 2 is arranged on the upper part of the base 1, the placement plate 3 is arranged on the upper part of the lifting plate 2, and the base 1, the lifting plate 2 and the placement plate 3 are aligned with each other; the hydraulic cylinder 6 is arranged in the middle position of the upper part of the base 1, and a push rod 61 is arranged in the hydraulic cylinder 6, the top end of the push rod 61 is connected to the lifting plate 2, and the push rod 61 is driven by the hydraulic system in the hydraulic cylinder 6 to drive the lifting plate 2 to move up and down; the lower part of the base 1 is provided with moving wheels 4, and the moving wheels 4 are arranged at the four corners of the base 1, and a plurality of groups of baffles 31 are arranged side by side on both sides of the upper part of the placement plate 3.

[0024] The lifting plate 2 and the placement plate 3 are of separate structures. The lower part of the base 1 can move by means of the moving wheels 4. The placement plate 3 is used to place the switch cabinet. Different types of placement plates 3 are configured for different types of switch cabinets, thereby solving the problem that the trolley cannot match the switch cabinet. The baffle 31 provided on the placement plate 3 can protect the switch cabinet to be protected, thereby preventing the equipment from slipping or colliding during transportation. The hydraulic system in the hydraulic cylinder 6 provides the power for lifting the lifting plate 2.

[0025] Among them, the upper part of the base 1 is provided with a fixed seat 11, and the fixed seat 11 is arranged in a ring array; the fixed seat 11 is connected to a sleeve 5 through a rotating shaft, and a telescopic rod 51 is arranged in the sleeve 5; the lower part of the lifting plate 2 is correspondingly provided with a movable seat 23, and the end of the telescopic rod 51 is connected to the movable seat 23 through a rotating shaft. A hydraulic rod is arranged in the sleeve 5, and the telescopic rod 51 is connected to the output end of the hydraulic rod; the fixed seat 11 is symmetrically provided with four groups. A slider 26 is arranged on the upper part of the movable seat 23, and a slide groove 21 is arranged at the lower part of the lifting plate 2, and a screw rod 22 is installed in the slide groove 21; the slider 26 is inserted into the slide groove 21, and the screw rod 22 passes through the thread hole on the slider 26; the screw rod 22 is driven by a servo motor embedded in the lifting plate 2.

[0026] The telescopic rod 51 in the sleeve 5 is driven by a hydraulic rod to move up and down, and the telescopic rod 51 is extended and retracted in the sleeve 5 to change the overall length; the end of the sleeve 5 is rotatably mounted on the fixed seat 11 and can only rotate; and the end of the telescopic rod 51 is rotatably mounted on the movable seat 23. In addition to being able to rotate, the movable seat 23 can also move along the slide 21. The servo motor drives the screw rod 22 to rotate, so that the screw rod 22 is engaged with the thread hole of the slider 26, thereby changing the position of the movable seat 23.

[0027] The position change of the movable seat 23 and the telescopic change of the sleeve 5 and the telescopic rod 51 will change the distance relationship between the base 1 and the lifting plate 2; the two can be used separately or in combination with each other, and can also be used in conjunction with the hydraulic cylinder 6 as a whole to provide auxiliary support and power, and also to avoid damage to the hydraulic cylinder 6 due to the heavy load structure.

[0028] Among them, the four corners of the upper part of the lifting plate 2 are provided with limiting holes 25, and the lower part of the placing plate 3 is correspondingly provided with limiting pins, and the limiting pins are correspondingly plugged into the limiting holes 25. The upper part of the lifting plate 2 is provided with a support plate 24, and the support plate 24 is provided as a strip plate, and the support plate 24 is evenly provided with multiple pieces.

[0029] The placement plate 3 is clamped in the limit hole 25 of the lifting plate 2 by the limit pin, and the position of the placement plate 3 is limited in this way, so that it can only be separated up and down, but cannot be offset in the horizontal direction, so as to ensure that the switch cabinet is arranged above the base 1 and keep the center of gravity stable. The support plate 24 supports the placement plate 3 after the placement plate 3 is placed. Multiple support plates 24 are arranged side by side and used together to play an auxiliary buffering effect, avoiding direct rigid contact between the lifting plate 2 and the placement plate 3. The buffer pad made of rubber material is arranged on the support plate 24 to improve the buffering protection effect.

[0030] Wherein, handles 34 are arranged on both sides of the placement plate 3, and the handles 34 are arranged in a C-shaped structure.

[0031] The setting of the handle 34 can facilitate picking up the placement plate 3 when replacing it, making it convenient for replacement and separation.

[0032] The baffles 31 are arranged side by side, and a U-shaped rope ring 33 is arranged on the side of the outermost baffle 31, and the opposite rope rings 33 are connected by a pull rope. A reinforcing plate 32 is arranged on the side of the baffle 31 facing away from the central axis of the placement plate 3, and the reinforcing plate 32 is arranged in a triangular shape, and the reinforcing plate 32 is fixedly connected to the placement plate 3.

[0033] According to the specifications of the switch cabinet, the placement plate 3 with different baffles 31 is replaced so that the baffles 31 fit on both sides of the switch cabinet; and the pull ropes between the corresponding rope rings 33 on the other two sides of the switch cabinet are used to tighten the switch cabinet, thereby ensuring the stability of the switch cabinet and playing a protective role.

[0034] The side of the moving wheel 4 is installed on the bracket 41 through a rotating shaft, and the top of the bracket 41 is fixed on the rotating seat 42; the rotating seat 42 is connected to the base 1 through a rotating shaft.

[0035] The upper part of the moving wheel 4 is installed on the lower part of the base 1 through a bracket 41 and a rotating seat 42, and the whole can rotate, thereby meeting the use requirements of the moving wheel 4.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] 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.
