Description

Technical Field

[0001] The utility model relates to the field of short-distance transport tools, in particular to a short-distance transport trolley for long materials. Background Art

[0002] With the rapid development of the construction engineering field, it is inevitable to transport short-distance, small-volume pipelines or long goods at construction sites. Most of these materials are long and heavy, and it is often very difficult to carry them manually during the construction process. However, lifting equipment cannot be used in a limited space working environment and the cost is high. Therefore, on-site workers often carry them manually or use flatbed trucks and trolleys on the construction site to transport pipelines. However, ordinary flatbed trucks and trolleys are prone to pipeline rolling and damage during the transportation of pipelines, so it is often necessary to fix the pipelines. When facing large and heavy pipelines, if the trolley is small and the trolley structure is unstable, the loaded pipelines need to be fixed and bundled. Therefore, the transportation efficiency is relatively low during implementation, which in turn affects the efficiency of pipeline construction and is time-consuming and labor-intensive.

[0003] The transportation of the transport carts in the prior art is greatly affected by the environment and materials, and the existing transport carts cannot lengthen the carriage according to the different lengths of the pipelines. Therefore, when transporting longer materials, the length of the fixed-length vehicle cannot meet the transportation needs. Due to the different requirements for different intervals, horizontal and vertical transportation, a variety of transport cart specifications have been produced. When transporting pipelines or other materials, a transport device with a relatively stable structure and convenient transportation is needed to transport long materials to improve construction efficiency.

[0004] Patents of some short-distance transport tools are disclosed in the prior art. Among them, the utility model patent with announcement number CN114715817A discloses a device for moving long pipes and long wooden boxes in a narrow area with the cooperation of a forklift. The patent includes a fixed seat, a base plate and a push rod. Both sides of the bottom end of the fixed seat are fixedly connected with the base plate, and two support rods are symmetrically installed in the middle of the top ends of the two base plates. The sides of the two support rods are provided with a plurality of plug holes, and the inner sides of the two symmetrically arranged plug holes are interspersed with fixed iron plates. A support platform is fixedly installed on one side of the fixed seat, and a steering wheel is fixedly installed on the bottom end of the support platform. A push rod is hingedly installed on the top end of the support platform, and a handle is fixedly installed on the top end of the push rod. Both sides of the handle are fixedly connected with adjustment rings through steel wire ropes, and the bottom ends of the two steel wire ropes pass through the handle and the inner side of the push rod and are fixedly connected to the steering wheel. Although the problem of long objects being easily damaged by friction with the ground is solved, using two forklifts at the same time is inconvenient for coordinated progress, which is time-consuming and laborious. The weight of the long objects may also damage the forklifts. There is a lack of an auxiliary structure to make the forklift's handling more convenient. In addition, there is still the problem that long materials cannot be easily transferred.

[0005] In view of this, the inventor conducted in-depth research on how to provide a long material short-distance transfer trolley to facilitate the transfer of long materials, which resulted in the present case. Utility Model Content

[0018] Beneficial effects:

[0019] The beneficial effects of the technical solution of the utility model are as follows:

[0020] (1) A tractor and a loader are used to transport long and large materials. Several loaders are arranged to assemble the loaders according to the different lengths of the materials to lengthen the materials. A steering device is fixedly arranged on the tractor, and the tractor and the loader are connected through the steering device.

This also improves the stability of the device during transportation, greatly improving the practicality of the device.

[0022] (3) When most transfer carts are transporting long and large materials through narrow areas, due to the limited width of the workshop door or the small width of the area, these objects that were originally transported horizontally must be put down first and then pushed vertically in the direction of the door. It is easy for part of the long object to rub against the ground and cause damage. The transportation process is time-consuming and labor-intensive, and the weight of the long object may also damage the forklift. The transfer cart of the present application completely avoids the above problems and realizes simple and convenient transportation of pipelines over short distances.
