Description

Separation of Top and Bottom Possible Electric Moving Car}

The present invention relates to an electric mobile trolley used for constructing, dismantling, and moving a structure, and more specifically, is separable into a lower body and an upper body, by using a single lift driving device to increase a lifting height of a moving object, and The present invention relates to an electric mobile truck that can be separated up and down to reduce installation costs and construction period by installing a height adjustment support between the sieve and the upper body.

In general, mobile trolleys are used in places where heavy materials, such as construction sites that transfer building members and production lines that produce large machines, are placed with minimal force while minimizing damage. The conventional mobile trolley has a plurality of trolley wheels for transferring the heavy goods and the bogie to the lower portion of the plate-shaped bogie to accommodate the heavy goods.

However, in recent years, as the necessity of constructing large structures due to social development increases, the frequency of construction of large structures such as buildings, subways, tunnels, and bridges increases. Building materials required for the construction of such a large structure also has a problem that the material transfer is difficult to enlarge. As the objects to be moved became larger and larger, the volume of the trolley for transporting them also increased. As such, the large-scale mobile truck has a problem that transportation is difficult in a narrow space such as a dense building area, a mountain canyon area, and a deep river section.

1 illustrates a side view of a mobile cart according to the prior art. As shown in FIG. 1, a height adjustment support 350 is installed to stably support a moving path of an enlarged integrated moving cart 2000. The height adjustment support 350, the installation place is high, or as the moving distance increases the construction cost and construction time exponentially. In addition, as the lower vent or the like is occupied by the lower space, passage is difficult, and there is a risk of flooding due to lack of water passage section. In addition, there is a problem that the construction period is delayed or prolonged due to the installation and removal of the vent.

This conventional moving trolley moves the moving trolley using a hydraulic system. However, since the hydraulic system must be fixedly installed, there is a limitation in the scope of installation of the structure, and it can be moved only in a predetermined direction of the front / rear or the left / right, making it difficult to adjust the direction and quickly responding to the direction change. In addition, the hydraulic system has a problem that the impact occurs during the initial movement and stop, the damage of the moving object due to the impact and the moving object fall from the moving cart can cause damage to the product or workers.

Therefore, the present invention was created to solve the above problems, by separating the lower body and the upper body, to reduce the installation area, and to install a height adjustment support on the separation surface can significantly reduce construction time and cost. An object of the present invention is to provide an electric mobile truck which can be separated vertically.

An object of the present invention as described above in the mobile truck for moving the moving object along the rail, a wheel for passing the rail, a lower plate provided on the upper wheel, a moving motor provided on one side of the lower plate, the power generated from the moving motor Lower body provided with a connection for transmitting to the wheel; The upper plate is provided at the top of the lower body and is separated from the lower plate, a plurality of guide posts provided in the corner portion of the upper plate, the lifting base for moving along the guide post and the lifting base for lifting up and down the lifting base It can be achieved by an electric movable trolley capable of vertically separating, including an upper body to be.

According to the present invention, there is an effect of separating the moving cart into the lower body and the upper body to improve the stroke range of the jack, thereby widening the utilization range of the moving cart. As the jack's stroke range is improved, the moving object can be stably moved by lowering the jack's rising height during the movement and passing the supporting beam between the guide posts. In addition, since a plurality of guide posts provided on the upper body divide and support the pressure applied to the jack, stable lifting and lowering of the moving object is possible, and the service life of the jack can be extended. In addition, the height adjustment support only need to be installed between the lower body and the upper body has the effect of reducing the construction cost and shorten the construction period to enter the height adjustment support.

Since the lower body and the upper body each have a separate motor, there is an effect that can quickly cope with emergencies such as failure or power failure.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
