Description

Adjustable transfer handcart

Technical Field

The utility model relates to an in put cabinet and transport handcart.

Background

Functional trolleys used by the 12KV centrally installed switchgear comprise a circuit breaker handcart, a PT handcart, an isolation handcart, a metering handcart and the like. At present, when a 12KV mid-cabinet used circuit breaker handcart, PT handcart, isolation handcart, metering handcart and the like are transported in equipment, the transportation handcart is required to be adopted to carry and transport, the difference in height and width is required to be distinguished during use, and the transportation handcart with different sizes cannot be used universally. The transfer handcart with various specifications is required to be configured in the transformer substation, so that a lot of space of the transformer substation is occupied, and the manufacturing cost of the transfer handcart matched with a user by a complete set of power distribution cabinet manufacturer is increased.

Disclosure of Invention

An object of the utility model is to overcome prior art's the aforesaid not enough, and provide an adjustable transportation handcart, adjustable automobile body height, width for reduce the configuration quantity of on-the-spot transportation handcart, and have simple structure, advantage that area is little.

The utility model adopts the following scheme: the trolley is characterized in that rollers are arranged below the trolley body, a tray is arranged on the trolley body through a screw assembly, handcart sliding guide rails for guiding the moving direction of a functional trolley are arranged on two sides of the tray, guide rods for matching and positioning with positioning holes in the cabinet body of the centrally-installed cabinet are arranged on two sides of the front end of the tray, a rear strip hole is formed in the middle of the rear end of the tray, an operating rod is movably hinged below the tray in a distribution manner, a buckling part for buckling at a clamping opening on the cabinet body of the centrally-installed cabinet is arranged at the front end of the operating rod, a front strip hole for yielding the buckling part is formed in the middle of the front end of the tray, the rear end of the operating rod extends out of the rear strip hole in the middle of the rear end of the tray, a pre-tightening spring for matching with the buckling part to work; the vehicle body comprises a lower base or is formed by assembling the lower base and a lifting seat through bolts, and hole sites for matching and assembling with the screw rod assembly are respectively arranged on the lower base and the lifting seat.

The tray includes little tray, big tray, the hole site is including the inner circle hole site that is used for fitting together the hole with little tray that is located the inner circle, be used for fitting together the outer lane hole site that is located the outer lane in hole with big tray.

The screw rod component comprises a screw rod and an adjusting wheel.

The buckling part is a protruding hook part positioned on the left side of the front end of the operating rod, the pre-tightening spring is positioned on the right side of the operating rod, and the handcart lock tongue is formed by fixing two screws on the rear part of the upper surface of the tray.

The utility model discloses a setting of seat and big or small tray is risen, can have two kinds of conversion modes in width and height, and a transportation handcart has realized four kinds of size dolly functions.

Detailed Description

In fig. 1-3, the utility model comprises a lower base 1, a lifting seat 2, a big tray and a small tray. Handcart sliding guide rails 8, screw rods 6, guide rods 11, buckle operating mechanisms and handcart lock tongues 9 are arranged on the large tray and the small tray. The lower base 1 is provided with a steering wheel 13, a directional wheel 12 and a lower base frame. The steering wheel 13 and the directional wheel 12 are respectively arranged at the front end and the rear end of the lower base frame, and hole sites for mounting large and small trays are arranged on the lower base frame. As the arranged hole sites need to support the weight of the handcart on the large pallet and the small pallet, reinforcing ribs 4 are manufactured at the positions of the hole sites for increasing the strength. The lifting seat 2 is fixed on the lower base 1, the height of the lifting seat is 240mm, the lifting seat can be detached, the height of the lifting seat after being detached is consistent with the size of the descending handcart cabinet body, and hole sites for mounting large and small trays are also arranged on the lifting seat frame. And reinforcing ribs are manufactured at the same positions of the hole positions for increasing the strength.

In fig. 4 and 5, the large tray and the small tray have the same structure, the large tray width 865mm is suitable for the cabinet with the width of L =1000mm, and the small tray width 665mm is suitable for the cabinet with the width of L2=800 mm. The buckle operating mechanism comprises an operating rod 10 and a pre-tightening spring. A protruding hook part is arranged on the left side of the front end of the operating rod 10, and the pre-tightening spring is arranged on the right side of the operating rod 10.
