Telescopic thatch cover device for vehicles

Abstract

The invention relates to a vehicle-mounted covering device. In order to solve the deficiencies of the existing vehicle-mounted thatch device, the vehicle telescopic thatch device provided by the present invention includes a carriage and a plurality of roof rods, and is characterized in that: the roof rods are in the shape of an inverted U, and when they are close to the roof rods The tent rods at the bottom of both sides are provided with radially fixed flat shafts, and free-rotating walking wheels are installed on the flat shafts, and the tent rods are connected by crank arms; the tent rods span the top of the carriage, The running wheels on the tent rods are supported on the top surface of the side wall of the carriage, and the first tent rod is fixed to the front panel of the carriage; it also includes a traction device, which is connected with the last tent rod by a wire rope, and the back and forth of the traction device The traction drives several awning rods on the top of the carriage to expand or contract sequentially. The vehicle thatch cover device has reasonable structure and convenient operation, and can be widely used in the airtight modification of various vehicle compartments.

Description

technical field [0001] The invention relates to a vehicle-mounted covering device, in particular to a vehicle-used telescopic thatch covering device. Background technique [0002] With the development of urban construction, the contradiction between the leakage problem in the transportation of bulk objects and the urban ecological environment has become increasingly prominent. In order to solve the problem of leakage in the transportation of bulk objects, various sealing devices for dump trucks have emerged as the times require. Patent No. 2011101167357, titled "Automatic Soft Canopy Covering System", Patent No. 2014203419972, titled "A New Type of Tarpaulin Top Cover Mechanism for Muck Vehicles", Patent No. 2013208354096, titled "Chain Drive Track Type Opening Tarpaulin Top In the basic design of the prior art, the tarpaulin is supported by the tent rods on the top of the carriage, and the expansion and contraction of the tarpaulin is realized through the reciprocating move...

Patent No. 2011101167357, titled "Automatic Soft Canopy Covering System", Patent No. 2014203419972, titled "A New Type of Tarpaulin Top Cover Mechanism for Muck Vehicles", Patent No. 2013208354096, titled "Chain Drive Track Type Opening Tarpaulin Top In the basic design of the prior art, the tarpaulin is supported by the tent rods on the top of the carriage, and the expansion and contraction of the tarpaulin is realized through the reciprocating movement of the tent rods. When the pole is used for traction operation, it is necessary to set up separate tracks on both sides of the carriage. There is a trolley in the track, and the tent pole is fixed on the trolley to walk along the track. However, the disadvantages of setting up a separate track are: first, the track is easily damaged , resulting in blockage of the block and twisting and damage of the tent rod; second, the track needs to be clean and smooth, and there are no obstacles inside, but it is difficult to keep the inside of the track clean during the operation of the muck truck; third, increasing the track increases the manufacturing cost, Increased manufacturing difficulty

In addition, the canopy pole across the top of the carriage requires its two sides to be synchronized when walking, otherwise it will cause the canopy pole to run stuck, twisted and deformed, but the synchronous traction device provided in the prior art is not reasonable enough, and the structure is relatively complicated
