[0002] Manual drum conveying apparatuses

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum conveying apparatus, and more particularly, to a passive drum conveying apparatus which is simple in construction and can be applied to drums of various sizes and has increased ease of use.

The drum is a universal large-capacity container for storing or storing various contents such as food, oil, and raw materials. Drums are made of metal and some are made of synthetic resin. Since a conventional drum has a capacity of 200 liters, it is difficult to handle it with the power of the person in the state of contents. Therefore, it is necessary to move and align the drum with the help of the equipment, and a drum conveying device is used for this purpose.

The drum conveying device has a manual drum conveying device which can be operated by a person alone. The manual drum conveying device has its own hydraulic jack so that it can lift a heavy object. However, conventional drum conveying apparatuses have a limited number of applicable drums. That is, only one kind of drum can be treated. The drum is provided on the market in various sizes. Therefore, drum conveying devices often become obsolete, which is uneconomical in many ways.

The drum conveying apparatus of the present invention is an apparatus that assists an operator in conveniently carrying a drum with his or her own force.

A rear wheel (13) is provided on the bottom surface of the base plate (10) for supporting the device. An arm 11 extending in a U shape is connected to the front of the base plate 10 by welding or the like so that the circumferential wall of the drum D can be partly surrounded. A front wheel (12) is provided at the tip of the arm (11). The arm 11 is formed by bending a pipe.

The post 14 is installed upright on the upper surface of the base plate 10. The post 14 is composed of two unit posts fixed to face each other. As shown in FIG. 2, the unit posts are bent in a diagonal shape to have a shape of a section having a constant cross-sectional shape along the length. Openings corresponding to the intervals between the unit posts are provided in the middle of the post 14 in the forward and backward directions. (Not shown) may be provided along the longitudinal direction of the post 14 so as to prevent the unit posts from spreading to each other.

A clamping portion 20 for clamping the drum D is installed so as to fit into the inner space S of the post 14 so as to be vertically movable along the longitudinal direction of the post 14. [ Hereinafter, the clamping portion 20 will be described with reference to Figs. 2 to 3. Fig.

The main link 23 is fitted in the internal space S between the posts 14. [ On both sides of the main link 23, rollers 24 are mounted. The roller 24 includes the main link 23 so that the clamping portion 20 can be smoothly moved in the vertical direction along the post 14. [ A plurality of rollers 24 may be provided and are supported on the inner circumferential surface of the post 14 to perform rolling motion.

The main link 23 is composed of two rods fixed in parallel spacing. A lower end of the upper jaw 21 is connected to a hinge 231 at the upper end of the main link 23. The upper jaw 21 and the lower jaw 22 to be described later perform a clamping function as a pair. At the tip of the upper tank 21 is provided a tooth 212 to be caught by the upper rim R of the drum.

The operation link 26 is connected to a hinge 211 at an upper portion of the upper tank 21 and extends downward. The operation link 26 extends to the lower portion of the main link 23. [ The operation link 26 is provided with a lower tank 22. The lower jaw 22 is mounted on the upper front of the operating link 26 and is supported on the bottom surface of the rim R of the drum. A tooth 222 made of a material having high hardness is attached to the lower tank 22 similarly to the upper tank 21.

One end of the coil spring 27 is connected to the lower end of the operating link 26 and the other end is connected to the upper portion of the main link 23. [ The coil spring 24 exerts a force on the actuating link 26 elastically in the direction in which the actuating link 26 is lifted up. The coil spring 27 elastically urges the teeth 212 of the upper tank 21 and the teeth 222 of the lower tank 22 away from each other. This is a driving force that causes the upper tank 21 and the lower tank 22 to return to the original state when the drum D is lowered.

A bumper mounting base curved at a curvature capable of wrapping the side wall of the drum D is installed in front of the main link 23. [ A bumper (15) is fixedly attached to the front surface of the bumper mounting base. The bumper 15 may be made of rubber or urethane for buffering action.

A hydraulic jack (30) for raising the clamping portion (20) in the vertical direction is fixedly mounted on the base plate (10). The hydraulic jack (30) has a hydraulic jack main body composed of a cylinder (31) and a piston (32); A foot lever (33) for pressing the foot to operate the hydraulic jack; And a release lever 34 for releasing the hydraulic pressure to lower the height again. The piston 32 of the hydraulic jack can lift the weight up by pushing the foot lever 33 up and down and the hydraulic pressure is released by rotating the release lever 34 in the counterclockwise direction to return the piston 32 to the cylinder 31 ), And can be caused to descend. The clamping portion 20 is connected to the piston 32 so that it can be vertically moved up and down by the operation of the hydraulic jack 30. [

However, according to the present invention, an extension portion 32a is further provided at an end portion of the piston 32 of the hydraulic jack 30. That is, the piston 32 of the hydraulic jack is extended longer. The length of the extended portion 32a may be 300 to 600 mm. The clamping portion 20 is connected to the extending portion 32a. The clamping portion 20 is connected to the extending portion 32a through a height adjusting connection portion so that the mounting height can be adjusted along the length direction of the extending portion 32a. That is, the height adjusting connection portion allows the clamping portion 20 to move along the longitudinal direction of the extending portion 32a. Thus, the drum conveying apparatus of the present invention can be applied to the drum D having a different height. The mounting height difference L of the clamping portion 20 can be adjusted to a degree equivalent to the length of the extending portion 32a.

The height adjustment connection may be configured as follows. That is, the extended portion 32a is a computation or sheath rod connected to the piston 32 so as to be rotatable about the piston 32 with respect to the piston 32. The clamping portion 20, in particular, the main link 23 is provided with a movable socket 25 which is screwed to the elongated portion 32a. At the end of the extension portion 32a, a rotation handle 35 capable of rotating the extension portion 32a is provided. Therefore, by rotating the rotary handle 35, it is possible to adjust the height of the clamping portion 20 up and down by the screw principle, without using the hydraulic jack. A coupling may be provided at a connecting portion between the piston 32 and the extended portion 32a to allow the extended portion 32a to rotate relative to the piston 32. [

This configuration is merely an example, and the installation height of the clamping portion 20 may be adjusted in various ways. For example, a pin hole may be formed at regular intervals along the longitudinal direction of the extended portion 32a, and a pin may be inserted into one of the pin holes to provide a clamping portion at a desired height.

According to the present embodiment, the height is adjusted by a screw, but the height of the chair can be adjusted by adjusting the height of the chair of the bicycle or by moving the accessory device (for example, a drill in a drilling machine) up and down One of various schemes can be employed.

An adjustment handle 16 is provided at the top of the post 14 in a form similar to a bicycle handle. The adjustment handle 16 is for adjusting and moving the drum conveying device including the post 14.

Hereinafter, the operation of the drum handler of the present invention will be described with reference to FIGS. 4 and 5. FIG.

The adjustment handle 16 is adjusted so that the arm 11 surrounds the drum D so that the drum transport device is adjusted and positioned in front of the drum D. The height of the clamping portion 20 is adjusted so as to match the height of the drum D by using the rotary handle 35. [

The drum D is positioned in the center of the drum clamping portion 20 and the teeth 222 of the lower jaw 22 are brought into close contact with the bottom surface of the rim R at the upper portion of the drum D . When the piston 222 is lifted by depressing the foot lever 33 of the hydraulic jack in a state in which the teeth 222 of the lower jaw are in close contact with the bottom surface of the rim R, the actuating link 26 does not climb up the rim R, The link 23 is raised. When the main link 23 is raised, the upper tank 21 is rotated by the principle of the link. When the main link 23 further ascends, the teeth 212 of the upper set are caught on the upper surface of the rim R, and the rim R is clamped together with the teeth 222 of the lower set 22. When the hydraulic jack 30 is continuously operated in this state, the upper tank 21 and the lower tank 22 more strongly clamp the rim R of the drum so that the drum D, which is a heavy material, It is possible to lift it away from the ground as if it were. When the drum D is lowered, the release lever 35 is used to release the hydraulic pressure, and the operation of the above operation is reversed.

The above description is only an example based on the technical idea of the present invention. Those skilled in the art will recognize that various modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims. For example, all embodiments described above may be freely combined and practiced by those skilled in the art, and any combination thereof should be construed as being included within the scope of the present invention.
