Detailed Description
As shown in fig. 1, the hard security fence carrying trolley for the transformer substation disclosed by the embodiment is composed of a mobile chassis 1 and support units 2, wherein the support units are arranged in parallel and detachably connected with the mobile chassis; when the support unit is assembled, the rigid safety fence is used for carrying, when the support unit is disassembled, safety tools such as grounding wires and equipment within 150 kilograms are transported.
The movable chassis 1 is L-shaped and comprises a flat frame 11 and a vertical frame 12 fixedly connected to the edge of the flat frame. As shown in fig. 1 and 2, the flat frame 11 is a rectangular frame formed by welding a pair of long rods and a pair of short rods, and a stay bar parallel to the long rods is provided therein. Pulleys 13 are arranged at four corners of the bottom surface of the flat frame and are a pair of front wheels and a pair of rear wheels, the front wheels are shockproof directional trundles, and the rear wheels are shockproof universal trundles with brakes. The upright frame 12 is a door-shaped frame, and a lock catch 4 which is matched and clamped with the supporting unit 2 is arranged on the upright post. The handle 5 is pushed outside the upright frame to push and pull.
As shown in fig. 3 and 4, the lock catch 4 is a rectangular buckle with an opening on the top surface, and the outer side of the lock catch is provided with a notch, and the width of the notch is matched with the width of the diagonal brace and the width of the hanging rod. The hasp welds outside the stand, during the assembly, guarantees support element 2 to connect reliably in going into the hasp with the support element card.
The supporting unit 2 is a triangular frame, the supporting performance of the supporting unit 2 on the hard fence in the transportation process is enhanced by using the stability of the triangle, and the supporting unit is composed of three parts, namely a hanging rod 21, a vertical rod 22 and an inclined strut 23. The hanging rod 21, the upright rod 22 and the inclined strut 23 are all strip-shaped rods, and inserting plates 24 are arranged at the inner end of the hanging rod and the bottom end of the inclined strut. And the hanging rod is sleeved with a limiting sliding sleeve 3, the top surface of the limiting sliding sleeve 3 is provided with a through hole, and the limiting sliding sleeve and the support rod are locked by a bolt screwed into the through hole, so that the fence is prevented from falling in the transportation process.
