Rainproof tarpaulin covering system of truck carriage

Abstract

The invention relates to a rainproof tarpaulin covering system of a truck carriage. The rainproof tarpaulin covering system of a truck carriage comprises a traction unit and tarpaulin, wherein the traction unit is arranged on a front portal frame and a rear portal frame of the carriage, the flexible traction part is arranged along the outer contour of the front portal frame or the rear portal frame, a driving mechanism is fixed on the carriage, and the flexible traction part is driven to move along the outer contour of the front portal frame and the outer contour of the rear portal frame through the driving mechanism; the tarpaulin is arranged between the two traction units of the front portal frame and the rear portal frame in a gantry shape, the edge of the left side of the front portalframe is fixed to the left side of the two traction units of the front portal frame and the rear portal frame, and the right side edges of the two traction units are fixed on the right sides of the two traction units of the front portal frame and the rear portal frame; and the tarpaulin is driven by the traction unit to be driven by the driving mechanism to be unfolded or folded from one side to the other side. The rainproof tarpaulin covering system has the beneficial effects that an external structure does not exist, the appearance of an existing truck can be well adapted, the action position is accurate, the action is smooth, and no cracking phenomenon exists.

Description

technical field [0001] The invention relates to the technical field of truck covering, in particular to a rainproof tarpaulin covering system for truck compartments. Background technique [0002] During the transportation of trucks, tarpaulins are usually used to cover and shield the compartments. This is considered from two aspects, one is from the environmental aspect, to prevent the dust from spreading, or the spilling of dirt, such as coal, etc.; the other is to protect the goods from being wet by rain during the long-term transportation. . [0003] Most trucks now use manual methods when covering the tarpaulin, that is, people drag the tarpaulin to the carriage, unfold the tarpaulin from one end to the other end, and then fix it on the hook around the carriage through the hanging ring ; There are also lifting methods such as forklifts that the tarpaulin is jacked up, and then manually fixed. Both methods require manual operation. If you want to cover the tarpaulin we...

Problems solved by technology

Both methods require manual operation. If you want to cover the tarpaulin well, you need repeated adjustments. However, the tarpaulin has a large area and it is very difficult to drag it. Not only is the labor intensity high and the work efficiency is low, but also people standing When adjusting the top of the car, it is easy to step on the air or slip, or even fall from the top of the car to the ground. There is also a certain risk for the person himself, and during the adjustment process, the tarpaulin is easily torn due to improper force and angle

[0004] At present, some mechanisms that use machinery to achieve covering have gradually appeared. Although they can realize the functions of covering and unfolding, they lack their own defects and are not practical enough.

It can be roughly divided into two categories, one is the method of stretching and unfolding. For example, a moving shaft is usually designed, and the driving mechanism drives the movement of the moving shaft. The moving shaft is connected to one end of the tarpaulin. When the moving shaft moves, the tarpaulin is unfolded. This type of driving mechanism requires peripherals, and its structure needs to occupy a certain volume on the carriage, which is very bloated, not only unsightly, but also when passing through certain narrow areas, such as passages or tunnels with limited height or width. , cannot pass, and if the driver is just used to ordinary trucks, it is easy to cause these raised and bloated drive mechanisms to collide with obstacles

The other is the way of rollers. The tarpaulin cover is in the shape of a gantry on the carriage. Therefore, rollers are installed at the positions of the gantry-shaped columns and beams, and the tarpaulin is rolled up by means of rollers. This type of setting It is not bloated, but when it is wrapped, the tarpaulin at the corner formed by the column and the beam will shrink into a pile. If the length of the truck is large and the tarpaulin is long enough, the space at the corner is not enough to accommodate more tarpaulins
