Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in figures 1-4, an anti-toppling handcart of a handcart type switch cabinet is characterized in that: including handcart chassis 100, handcart chassis 100 bottom is equipped with at least a set of guide bar subassembly 200, guide bar subassembly 200 includes preceding horizontal guide 201, back horizontal guide 202 and is used for promoting preceding, back horizontal guide respectively from the preceding, the spring that the rear side of handcart chassis stretches out, every horizontal guide bar position all is equipped with the guide bar cover of fixed connection on handcart chassis, horizontal guide bar and corresponding guide bar cover sliding fit and pass from wherein. When the handcart is in the running position, the rear horizontal guide rod is pressed in under the action of a baffle in the switch cabinet, the rear end of the rear horizontal guide rod is flush with the rear side of the chassis of the handcart, and the front horizontal guide rod 201 extends out of the front side of the chassis of the handcart under the action of the tension of a spring; when the handcart is at a test position and the cabinet door is in an open state, the rear horizontal guide rod 202 extends out of the rear side of the chassis of the handcart under the action of spring tension, and the front horizontal guide rod 201 extends out of the front side of the chassis of the handcart under the action of spring tension; when the handcart is at a test position and the cabinet door is in a closed state, the rear horizontal guide rod 202 extends out of the chassis of the handcart under the action of the tension of the spring, and the front horizontal guide rod 201 is pressed into the chassis of the handcart under the action of the cabinet door; when the handcart is in an overhauling state, the front horizontal guide rod and the rear horizontal guide rod extend out of the chassis of the handcart under the action of spring tension, if the handcart is out of balance and inclines forwards and backwards, the horizontal guide rod is firstly contacted with the ground to support the handcart, so that the handcart is limited from being toppled over due to excessive inclination, and the depth size of the chassis of the handcart is equivalently enlarged, so that the stability of the handcart is improved, the method is adopted to conveniently transform the existing floor type handcart, and the safety of the floor type handcart is improved.
In this embodiment, the guide rod sleeve is composed of an inner guide rod sleeve 120 and an outer guide rod sleeve 110, a spigot 250 with an upward opening is provided at the middle section in the length direction of the front and rear horizontal guide rods, the spigot of the front horizontal guide rod is in clamping fit with the corresponding outer guide rod sleeve when the front horizontal guide rod extends out from the front side of the handcart chassis 100 in an outward sliding manner, and the spigot of the rear horizontal guide rod is in clamping fit with the corresponding outer guide rod sleeve when the rear horizontal guide rod extends out from the rear side of the handcart chassis in an outward sliding manner; when the horizontal guide rod is in an extending state, the handcart can be clamped at the position of the outer guide rod sleeve due to the seam allowance of the horizontal guide rod when the handcart inclines, and therefore the horizontal guide rod is effectively prevented from being forced into a chassis of the handcart to be invalid.
In this embodiment, the springs are composed of a front spring and a rear spring, the front springs are two and symmetrically distributed on two sides of the front horizontal guide rod, the rear springs are two and symmetrically distributed on two sides of the rear horizontal guide rod, the outer guide rod sleeves are fixedly connected with outer connecting plates for connecting the springs, and inward ends of the front horizontal guide rod and the rear horizontal guide rod are also fixedly connected with inner connecting plates for connecting the springs; the front and rear horizontal guide rods are identical in structure but are oppositely oriented.
For example, a handcart with the height of 1.6 m, the chassis depth of 0.5 m and the wheel base of 0.4 m, and the height-depth ratio is 4. When the handcart is in an overhauling state, the front horizontal guide rod and the rear horizontal guide rod both extend outwards for 0.25 m, and the height-depth ratio is reduced to 1.6, so that the stability of the handcart is improved, and the handcart is prevented from being toppled over due to excessive inclination.
