Ascending-free manual truck tarpaulin cover reel device

Abstract

The invention relates to a vehicle cover device, in particular to an ascending-free manual truck tarpaulin cover reel device. An universal transmission device comprises a single cross shaft universalcoupling including a first cross shaft universal joint, or a double cross shaft universal coupling including the first cross shaft universal joint and a second cross shaft universal joint, or a movable fastening assembly including a first arc segment connector and a second arc segment connector; a flexible cover tarpaulin is arranged directly behind a headstock positioned at the front part of an unenclosed dropside truck and internally provided with a driving operating room, and the upper end of a front transverse chamber wall arranged at the front end of a carriage connected with the headstock; and the straight segment edge of the front end of the flexible cover tarpaulin is fixed on a tarpaulin retracting shaft; one end of the tarpaulin retracting shaft is movably connected to the top ends of first drive rods by universal transmission devices. The device is reasonable in structure, is simplified, is low in purchase cost, saves time and labor in the process of manual operation, and ismore convenient to use.

Problems solved by technology

[0002] At present, in order to solve the problem of environmental pollution caused by dust or dust dispersed in the air from the opening of the muck, coal, etc. transported by the open railing trucks, which are disturbed by the air flow during the transportation process and save time and effort (Replacing manual labor) The time-consuming and labor-intensive problem of automatically covering the opening of the open railing truck (trailer or semi-trailer) compartment, various automatic methods that can effectively cover the opening of the open railing truck compartment Or semi-automatic carriage cover devices emerge in endlessly through the disclosure of technical documents, but there is also a technical problem in existing various automatic or semi-automatic carriage cover devices: automatic or semi-automatic carriage cover devices need motors, mechanical transmission mechanisms, hydraulic drive cylinders, hydraulic pressure The transmission mechanism, guide rail, wire rope and / or rollers and other traction tarpaulins cover the open of the carriage in the moving state. However, it is well known that the automatic or semi-automatic automatic The structure of the compartment cover device is relatively complicated. If the automatic or semi-automatic compartment cover device is not regularly maintained manually and works in a dusty environment, the increase in the dynamic friction resistance of the equipment will inevitably shorten its working life. Therefore, although the existing automatic Or the semi-automatic carriage covering device has achieved the technical purpose of automatic covering, but the purchase cost of realizing the function of automatic covering is a considerable amount of money for transportation companies that rigidly require automatic or semi-automatic carriage covering devices Moreover, if it is installed on an open-type rail truck, it will be deemed as an illegal modification of a motor vehicle by the vehicle management office; in order to reasonably prolong the working life of the existing automatic or semi-automatic carriage cover device, the transportation company also needs to pay for regular maintenance. The cost of the automatic or semi-automatic compartment covering device is regularly maintained by manual labor; in addition, although the structure of the manual compartment covering device or means that can effectively cover the opening of the truck compartment with open railings is quite simple, it requires The driver and / or stevedorer of the open-type rail truck cooperates to climb to the top of the compartment and manually shift the tarpaulin to cover the opening of the compartment and fix it with the compartment. Therefore, the artificial compartment cover with a relatively simple structure Although the purchase cost of the device or means is low, and it will not be recognized as an illegal modification of a motor vehicle by the vehicle management office if it is installed on an open-type rail truck, it is still time-consuming and laborious, and it is not convenient enough to use
