Description

Technical Field

[0001] The utility model relates to the technical field of industrial transportation equipment, in particular to a parts handling and transportation device for a tower crane. Background Art

[0002] Tower cranes, also known as tower cranes, are the most commonly used lifting equipment on construction sites. They are constructed of connected sections and are used to lift materials such as rebar, wood planks, concrete, and steel pipes. They are an essential lifting equipment on construction sites. The function of a tower crane is to bear the upper load transmitted by the boom and counterarm cables, and transmit this load directly to the tower structure through the rotating tower turntable, bearings, and other structural components. Self-elevating tower tops can be truncated cone-shaped, forward- or backward-inclined cone-shaped, herringbone-shaped, or diagonally braced.

[0003] During the assembly of tower cranes or the production of parts, it is necessary to transport and move the parts that are packaged in standard form. The general method of transportation is to use vehicles. However, the doors of vehicles are usually at a certain distance from the ground. When transporting, tools such as ramps are used for transportation, which may cause a certain degree of slippage. In addition, for efficiency, the parts boxes must be transported in groups. Grouped boxes are generally heavier, and during the transportation process, the operator needs to bend down to different degrees to carry them, which is more laborious. Utility Model Content

[0030] Example

[0031] Reference Figures 1 - 4The present technical solution provides a parts handling and transportation device for a tower crane, which includes a main support 1, a transportation mechanism 2 is provided on the main support 1, and the transportation mechanism 2 includes: a first vertical three-wheeled wheel 201, a vertical mounting rod 202, a transportation platform 203, a toggle round table 2033, and a counterweight cylinder 204. The two sides of the first vertical three-wheeled wheel 201 are respectively provided with a second vertical three-wheeled wheel 2011 and a third vertical three-wheeled wheel 2012. The first vertical three-wheeled wheel 201, the second vertical three-wheeled wheel 2011 and the third vertical three-wheeled wheel 2012 are all provided with a first rope 2013. The top and bottom of the vertical mounting rod 202 are respectively provided with an oblique rod 2021 and an oblique round rod 2022. The transportation platform 203 is sleeved on the oblique rod 2021. One side of the transportation platform 203 is provided with an oblique movable rod 2031 through a movable shaft. One side of the transportation platform 203 is fixedly connected to a limited position protrusion 2032. 033 is arranged on one side of the top of the frame of the main bracket 1, and the counterweight cylinder 204 is sleeved on the oblique round rod 2022. By setting up the conveying mechanism 3, the conveying base plate 305 carrying a box of parts will reach a balanced state with the short counterweight block 3042. In terms of height, the conveying base plate 305 will only drop partially instead of being directly pressed to the bottom. Similarly, after the second box of goods enters the top of the conveying base plate 305, the two boxes of goods will be in a balanced state with the short counterweight block 3042 and the middle counterweight block 3041. Similarly, the final effect is that after each parts box enters the conveying mechanism 3, the top is at the same height and there is no excessive drop. While protecting the goods, it also prevents the operator from bending over too much. In addition, an additional conveying mechanism 3 can be set up in the car, and the transported parts boxes are stacked in the conveying mechanism 3, which also reduces the labor intensity of the staff in the car.

[0032] Reference Figures 1 - 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that a cavity is opened inside the counterweight cylinder 204, and a counterweight block is fixedly connected to the bottom of the cavity of the counterweight cylinder 204, and the counterweight block is fixedly connected to the bottom of the cavity. The first rope 2013 passes around the side surfaces of the first vertical three-wheeled wheel 201, the second vertical three-wheeled wheel 2011 and the third vertical three-wheeled wheel 2012 in turn, and the two ends of the first rope 2013 are respectively connected to the transport platform 203 and the side of the counterweight cylinder 204.

[0033] Reference Figures 1 - 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that the bottom of the oblique rod 2021 and the vertical mounting rod 202 are fixed and the main bracket 1 is fixedly connected. The inclination angles of the oblique rod 2021 and the vertical mounting rod 202 are consistent, and the two ends of the oblique round rod 202 are respectively fixedly connected to the side of the vertical mounting rod 202 and the main bracket 1.

[0034] Reference Figures 1 - 4, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the first vertical three-wheel 201, the second vertical three-wheel 2011, and the third vertical three-wheel 2012 are all connected by a connecting plate and a vertical mounting rod 202, and the connecting plate is inclined and not located on the rotating shafts of the three wheels.

[0035] Referring to Figures 1 - 4 , based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a handling mechanism 3 is provided on one side of the main bracket 1. The handling mechanism 3 includes symmetric vertical frames 301. A horizontal three-wheel 302 is provided at the top of the symmetric vertical frames 301. A second rope 3021 is provided on the surface of the wheels of the horizontal three-wheel 302. By providing the handling mechanism 3, the handling bottom plate 305 carrying a box of parts will reach a balanced state with the short counterweight 3042. In terms of height, it means that the handling bottom plate 305 will only descend partially instead of being directly pressed to the bottom. Similarly, after the second box of goods enters above the handling bottom plate 305, the two boxes of goods will be in a balanced state with the short counterweight 3042 and the medium counterweight 3041, and so on. The final effect is that after each parts box enters the handling mechanism 3, the tops are all at the same height and there is no excessive falling amplitude. While protecting the goods, it also saves the operator from excessive bending. In addition, an additional handling mechanism 3 can be provided in the carriage to stack all the transported parts boxes in the handling mechanism 3, and at the same time, it also reduces the labor intensity of the staff in the carriage.

[0036] Referring to Figures 1 - 4 , based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that an upper limit platform 303, a middle limit platform 3031, and a lower limit platform 3032 are successively provided on the outer side surface of the symmetric vertical frame 301 from top to bottom. A long counterweight 304, a medium counterweight 3041, and a short counterweight 3042 are respectively lapped on the top surfaces of the upper limit platform 303, the middle limit platform 3031, and the lower limit platform 3032. The lengths of the three counterweights are different but the weights are the same.

[0037] Referring to Figures 1 - 4 , based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that a handling bottom plate 305 is sleeved on the frame body of the inner side surface of the symmetric vertical frame 301. An insertion block 3051 is inserted on the side surface of the handling bottom plate 305. The insertion block 3051 can install an additional structural plate to cope with a larger handling box, and the larger handling box needs to be placed by rotating 90 degrees.

[0038] Referring to Figures 1 - 4, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that the part of the second rope 3021 located on one side of the symmetric vertical frame 301 sequentially passes through the long counterweight 304, the middle counterweight 3041, and the short counterweight 3042. Limit disks 3022 are provided at both ends of the second rope 3021. The limit disk 3022 at one end of the second rope 3021 is located on the lower surface of the short counterweight 3042, and the limit disk 3022 at the other end of the second rope 3021 is located on the lower surface of the handling bottom plate 305.

[0039] Specifically, the working process or principle of this kind of part handling and transporting device for tower cranes is as follows: In the state of being naturally free from external forces, the weight of the counterweight cylinder 204 is greater than the weight of the transport platform 203. Under the action of the first rope 2013, the counterweight cylinder 204 is at the lowest point, while the transport platform 203 is at the highest point. When handling the parts of the tower crane, an operator stands at the door of the transport truck, places this device on the side of the door, and places the goods on the transport platform 203 of the transport mechanism 2. After a load is applied to the transport platform 203, the transport platform 203 together with the parts and goods will move obliquely downward. At this time, the counterweight cylinder 204 is pulled to the highest position. When the goods on the transport platform 203 reach the lowest point, the dialing frustum 2033 will lift the bottom end of the inclined movable rod 2031, causing the top end of the inclined movable rod 2031 to shift downward, and then the part handling box on the transport platform 203 can be released. After the transport platform 203 loses the load, it is pulled up to the highest point under the gravity of the counterweight cylinder 204. In terms of the overall transport mechanism 2, it means that the transport platform 203 moves to one end after placing the goods, releases the goods after reaching the predetermined place, and then returns to the initial point for the next transport, repeating this cycle. After the part transport box leaves the transport mechanism 2, it will enter the handling mechanism 3. In the natural state, the long counterweight 304, the middle counterweight 3041, and the short counterweight 3042 will naturally lean on the upper limit platform 303, the middle limit platform 3031, and the lower limit platform 3032 without external forces. After setting the long counterweight 304, the middle counterweight 3041, and the short counterweight 3042 to approximately the same gravity as the fully loaded transport box, when the first transport box enters the upper surface of the handling bottom plate 305, the short counterweight 3042 is lifted up. At this time, the handling bottom plate 305 will descend. However, since the short counterweight 3042 is approximately equal in weight to the first box of parts, the handling bottom plate 305 carrying one box of parts and the short counterweight 3042 will reach a balanced state. In terms of height, it means that the handling bottom plate 305 will only descend partially rather than being directly pressed to the bottom. Similarly, after the second box of goods enters above the handling bottom plate 305, the two boxes of goods will be in a balanced state with the short counterweight 3042 and the middle counterweight 3041, and so on. The final effect is that after each part box enters the handling mechanism 3, the top is at the same height and there is no excessive falling amplitude.

[0040] It should be noted that each rope and the rotating wheel are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail herein.
