Description
Technical Field
The invention relates to a centrally installed switchgear transfer trolley, in particular to a variably adjustable centrally installed switchgear transfer trolley.
Background
The centrally installed switchgear is armored centrally installed metal-enclosed switchgear and is divided into three layers, the upper layer is a bus and an instrument room, the middle layer is a breaker room, and the lower layer is a cable room. The transfer trolley is used as an important accessory of the centrally installed switchgear, and is mainly used for safely moving out the circuit breaker handcart from the interior of the centrally installed switchgear and conveying the circuit breaker handcart to other positions when the centrally installed switchgear is installed, debugged and overhauled, and the transfer trolley needs to be moved into the centrally installed switchgear after the centrally installed switchgear is installed, debugged and overhauled.
The conventional transfer trolley commonly used at present mainly has the following defects that firstly, the structural design is unreasonable, the height adjustment is inconvenient in the height butt joint process of the switch cabinet, the nylon hand wheels on four bearing bolts are respectively adjusted to realize the purpose, and the adjustment speed is slow. Secondly, the transfer trolley has various specifications of height and width, poor universality and poor operating performance. The circuit breakers are generally in two specifications of 800mm and 1000mm, the heights of circuit breaker installation guide rails in the switch cabinet are different and are generally about 480mm and 800mm, so that transfer vehicles with different heights and widths are required to be arranged, the transfer vehicles with various specifications not only occupy field sites, but also have high cost, two transfer vehicles with various specifications are required to be arranged in each specification in the power distribution room, the fault circuit breakers can be conveniently moved out of the switch cabinet for maintenance, and the normal circuit breakers can be rapidly moved into the switch cabinet, so that the normal operation of a power supply line is realized, and the long-time power failure of the power supply line caused by the fault of the circuit breakers is avoided, and the production loss is brought.
Disclosure of Invention
The invention aims to provide a variable-type adjustable centrally installed switchgear transfer trolley to solve the technical problem that the size of the traditional transfer trolley is not convenient to adjust.
The invention provides a variable-type adjustable centrally installed switchgear transfer trolley which is characterized by comprising
The transfer trolley main body structure comprises a bottom fixed seat, a supporting rod and a guide rail platform arranged at the top of the supporting rod;
the height adjusting mechanism comprises a spring lock structure arranged inside the supporting rod and a fine adjusting rod arranged on the outer ring of the supporting rod;
the spring lock structure comprises a locking plate, a first spring, a baffle and a reset structure, wherein the locking plate is provided with a clamping groove; in a non-use state, the reset structure limits the lock plate in the support rod; when the support rod ascends, the reset structure slides upwards, the locking plate is popped up under the action of the first spring, the clamping groove is aligned with the top of the fine adjustment rod, and the support rod falls to interlock with the locking plate and the fine adjustment rod to complete the upward adjustment operation; when the locking plate descends, the supporting rod is lifted upwards, the resetting structure automatically slides downwards after the locking plate leaves the fine adjustment rod, the locking plate resets, and the supporting rod descends to complete downward adjustment operation.
In detail, under non-user state, because the limiting action of reset structure, the locking plate is located the bracing piece, consequently, can not restrict the bracing piece and in the intraductal free slip of fine setting, at this moment, first spring is in the extension state, the locking plate receives the pulling force of first spring, and when the platform was gone up to needs, the bracing piece that rises exceeded the fine setting pole to the bottommost of locking plate, the reset structure that slides upwards, the locking plate pops out the fine setting pole, because the positioning action of baffle, behind locking plate rotary motion to the baffle, the draw-in groove was aimed at with the fine setting pole top, only needs slightly descend the bracing piece, falls into the fine setting pole with the draw-in groove, can realize the interlocking, accomplishes the operation of transferring to the throne. In the use, if the mistake touches reset structure, the locking plate pops out the bracing piece, because the restriction of fine setting pole, when the locking plate bottommost does not surpass the fine setting pole, the locking plate can be in the fine setting pole, can not influence the slip of bracing piece.
Further, when the platform needs to be lowered, the supporting rod only needs to be lifted upwards, the clamping groove of the locking plate leaves the top end of the fine adjustment rod, the reset structure automatically slides downwards, the locking plate is accommodated in the supporting rod, the locking plate resets, and the supporting rod descends.
Further, the reset structure comprises a sliding frame arranged on the supporting plate and a reset plate, and the reset plate is connected with the sliding frame through a second spring;
