Description

Technical Field

[0001] The utility model belongs to the technical field of transport vehicles, and in particular relates to a flexible small-sized short-distance transport device. Background Art

[0002] In various environmental protection construction scenarios, a large number of short-distance transportation operations of various materials are usually involved, such as consumables for environmental protection construction, spare parts for engineering equipment and devices, etc. It can be said that the transfer and transportation efficiency of various materials greatly affects the efficiency of project construction and determines the labor cost of the construction project. Various materials used on the project site, including consumables and spare parts, are usually heavy. When using traditional small transport trailers to transfer and transport materials, it is inevitable to avoid many handling operations of materials to and from the trailer. Such handling operations are very time-consuming and labor-intensive, which seriously affects the efficiency of transfer and transportation, and consumes a lot of manpower. On the other hand, different types of materials are usually suitable for transportation in different ways. For example, some materials are suitable for being placed directly on the trailer, and some materials are suitable for being connected to the trailer and towed by the trailer.

[0003] The existing small-scale transport devices are difficult to meet the above requirements, resulting in low construction efficiency, high manpower consumption, and in some cases, easy to generate transportation operation dangers, and the transportation method is single. Therefore, it is necessary to develop and design a new type of small-scale transport device to solve the above technical problems. Utility Model Content

[0014] The advantages and positive effects of the utility model are:

[0015] The utility model provides a flexible small short-distance transport device for assisting the transfer and transportation of materials at various construction sites. Compared with existing auxiliary transport devices such as small trailers, the transport device in the utility model uses a telescopic fork frame and an electric push rod to provide a lifting and driving action for the support transfer assembly on which the lifting plate is installed. In this way, when materials need to be loaded onto the transport device or unloaded from the transport device, the lifting plate can be lowered to a low position, which can reduce the labor intensity when carrying materials upward or downward, improve the efficiency of material handling and transportation, and reduce the demand for manpower. At the same time, since materials can be loaded and unloaded more conveniently, the danger of material loading and unloading operations is also reduced to a certain extent.

[0016] The roller support mechanism of the support transfer assembly supports the materials, and the materials can be pushed and moved by the push mechanism. The push mechanism provides an auxiliary unloading function for heavier materials, which further reduces the consumption of manpower. The transportation device in the utility model has the use modes of material carrying transportation and dragging and hoisting transportation of materials by hoisting assemblies and clamping assemblies, which can meet the transportation needs of different types of materials.

A hoisting component is installed in front of the lifting plate 3, and a clamping component is installed at the front end of the hoisting component. Under the driving action of the electric push rod 5, the telescopic fork frame 9 performs a telescopic action, and the lifting plate 3 performs a lifting and moving movement accordingly, thereby lifting and moving the support transfer component 2, the lifting component and the clamping component, wherein the support transfer component 2 is used for carrying-type transportation of materials, and the hoisting component and the clamping component are used for dragging-type transportation of materials.

[0028] As shown in the figure, the telescopic fork frame 9 includes a cross-shaped fork frame on the left and a cross-shaped fork frame on the right.

The bottom front ends of the two cross-shaped forks are hingedly connected to the chassis 4, the bottom rear ends of the two cross-shaped forks are overlapped on the chassis 4, and the top rear ends of the two cross-shaped forks are against the lower surface of the lifting plate 3. When the telescopic fork frame 9 performs a telescopic action, the bottom rear ends of the two cross-shaped forks slide forward or backward on the chassis 4. In order to improve the stability of the sliding movement, tracks can be set on both sides of the rear part of the chassis 4 and track blocks can be installed on the tracks, so that the bottom rear ends of the two cross-shaped forks are hingedly connected to the two track blocks.

[0029] In this embodiment, a bottom box 6 is installed at the lower middle part of the chassis 4, a controller and a battery are installed in the bottom box 6, and the electric push rod 5 and the driving motor of the driving assembly 7 are connected to the controller.

Roller support mechanisms 2-4 are installed on both sides of the support plate 2-1, and a push mechanism for pushing materials placed on the roller support mechanism 2-4 is also installed on the support plate 2-1.

[0032] The left and right roller support mechanisms 2-4 are used to carry materials. As shown in the figure, the roller support mechanism 2-4 includes a long roller base fixedly installed at the side edge of the support plate 2-1, and a plurality of rollers of equal height are installed on the roller base. Generally, materials to be transferred and transported in a load-bearing manner are placed on a regular pallet, and the pallet is placed on the support transfer assembly 2 and supported by the left and right roller support mechanisms 2-4. When loading materials, the material pallet is slid backward, and conversely, when unloading materials, the material pallet is slid forward until it is separated from the short-distance transport device. The purpose of setting up a pushing mechanism is to limit the pallet when the material pallet is loaded, and to assist in pushing and unloading the pallet when the material pallet is unloaded.

[0033] In this embodiment, the pushing mechanism includes a screw 2-3 installed above the middle part of the support plate 2-1, and a transmission mechanism 2-7 is installed at the rear part of the support plate 2-1 through a support seat 2-8. The output shaft of the transmission mechanism 2-7 is docked with the end of the screw 2-3, and the input shaft of the transmission mechanism 2-7 is docked with a drive shaft. The drive shaft is perpendicular to the screw 2-3 and its end extends to the edge of the support plate 2-1 and is installed with a handwheel 2-6. A pushing beam 2-5 is installed on the nut of the screw 2-3.

[0034] The driving action is input through the hand wheel 2-6 and the driving axial transmission mechanism 2-7, and the transmission mechanism 2-7 drives the lead screw 2-3 to move forward or reverse, and correspondingly pushes the cross beam 2-5 to move forward or backward. The transmission mechanism 2-7 includes a housing and a worm gear assembly located in the housing, the worm gear is installed on the output shaft, and the end of the worm gear extends from the housing to form an input shaft.
