Abstract

The present invention relates to a transport cart of a new structure that allows for easy direction adjustment while loaded with heavy objects. The transport trolley according to the present invention comprises a storage box (A) having a cylindrical shape with an open top surface, a pair of fixed wheels (30) provided on both sides of the central part of the storage box (A), and front and rear casters (41, 42) provided on the front and rear of the storage box (A). When the trolley is rotated, a moment is applied to the fixed wheels (30), allowing the trolley to be rotated with less force compared to conventional transport trolleys, thereby having the advantage of preventing injury to the worker.

  5. In Paragraph 2, A slider (44) coupled to the lower side of the storage box (A) so as to be slidable in the front and rear directions, and It further includes a position adjustment means (45) connected to the slider (44) to adjust the forward and backward position of the slider (44), and The fixed wheel (30) is provided on the lower side of the slider (44) so as to be spaced laterally from each other. A transport cart characterized by being able to adjust the position of the slider (44) in the forward and backward directions using the position adjustment means (45) while a heavy object is loaded in the storage box (A), so that the fixed wheel (30) is positioned below the center of gravity of the object loaded in the storage box (A).

Description

Carrying cart The present invention relates to a transport cart, and more specifically, to a transport cart of a new structure that allows the direction to be easily adjusted while a heavy object is loaded, and also allows the heavy object to be easily discharged. Generally, when manufacturing parts using machine tools, large quantities of chips generated or manufactured parts are transported while loaded on a transport cart. FIGS. 1 and 2 illustrate an example of a transport cart used for loading such chips or parts, comprising a storage box (1) configured in a tubular shape with an open top surface, a pair of fixed wheels (2) provided on both front sides of the lower side of the storage box (1), and a pair of casters (3) provided on both rear sides of the lower side of the storage box (1). The above storage box (1) is made of a high-strength metal material and is provided with a handle (4) on the rear side so that a worker can hold the handle (4) and push the storage box (1) or adjust the direction of the storage box (1). The above fixed wheel (2) is coupled to the lower side of the storage box (1) so that its periphery faces in the front-rear direction. The above caster (3) is connected to the lower side of the storage box (1) so as to be freely directionally adjustable. Therefore, when a worker holds the handle (4) and pushes the storage box (1) to rotate it sideways, the caster (3) rotates, and the direction of the storage box (1) is adjusted. Meanwhile, when the transport cart is filled with chips or parts, the weight of the transport cart becomes very heavy, so a large load is placed on the caster (3), and the caster (3) cannot change direction smoothly. In addition, when the caster (3) cannot be smoothly turned in this manner, if the worker pushes the transport cart sideways to adjust the direction, not only is a very large force required, but a large burden is placed on the worker's body, and the worker is frequently injured. As mentioned above, this problem occurred equally in all types of trolleys transporting heavy goods, not just those transporting chips and parts. Therefore, a new method to solve these problems became necessary. FIG. 1 is a side view illustrating a conventional transport cart, FIG. 2 is a lower side view of a conventional transport trolley, FIG. 3 is a side view illustrating a transport cart according to the present invention. FIG. 4 is a front view illustrating a transport cart according to the present invention, FIG. 5 is a lower side view of a transport trolley according to the present invention, FIGS. 6 to 9 are reference drawings illustrating the operation of a transport cart according to the present invention. FIG. 10 is a lower side view illustrating a second embodiment of a transport cart according to the present invention, FIG. 11 is a side cross-sectional view of a second embodiment of a transport trolley according to the present invention. The present invention will be described in detail below with reference to the attached exemplary drawings. FIGS. 3 to 9 illustrate a transport cart according to the present invention, comprising a storage box (A) having a cylindrical shape with an open top surface, a pair of fixed wheels (30) provided on both sides of the central part of the storage box (A), and front and rear casters (41, 42) provided on the front and rear of the storage box (A). The storage box (A) comprises a main body (11) with open upper and lower surfaces, an opening/closing plate (12) which is rotatably coupled to one side of the lower end of the main body (11) in an upward and downward direction to open and close the lower side of the main body (11), and a fixing means (20) which is provided on the main body (11) and coupled to the front end of the opening/closing plate (12) to fix the opening/closing plate (12) so as to block the lower side of the main body (11). The above main body (11) is configured in a rectangular tube shape that is long in the front-to-back direction and narrow in the side direction, and has open top and bottom surfaces. In addition, a coupling hole (11a) penetrating both sides is formed on the upper side of both sides of the main body (11), and as shown in FIGS. 7 to 9, a device inserted into the coupling hole (11a) is configured to lift the transport cart upward. The above device utilizes the fork (6) of a forklift, and with the fork (6) inserted into the coupling groove, the fork (6) is raised to lift the entire transport cart upward, and the forklift is moved to move the transport cart. The above opening/closing plate (12) is made of a high-strength rectangular metal plate, and its rear end is connected to the rear side of the main body (11) by a hinge (12a) so as to be rotatable in the up-and-down direction. Accordingly, when the opening/closing plate (12) is rotated upward, the lower side of the main body (11) is sealed so that various objects can be placed inside the storage box (A), and as shown in FIG. 9, when the opening/cl
