Description

Technical Field

[0001] The utility model relates to the technical field of industrial buildings, and particularly relates to a self-loading and unloading multi-dimensional board clamping and lifting mechanism. Background Art

[0002] The application of multi-dimensional high-strength boards has gradually emerged with the continuous improvement of the society's requirements for the performance of building materials and the pursuit of environmental protection and energy-saving concepts. Due to its excellent properties such as high strength, high toughness, high wear resistance, high corrosion resistance, sound insulation and heat insulation, as well as light weight, beauty, easy processing and other characteristics, it has been widely used in the field of industrial buildings.

[0003] When the main structure of a large-scale batching warehouse adopts a steel frame structure and multi-dimensional high-strength boards are used as roof panels, wall panels, etc., the factory building is surrounded on three sides and it is impossible to stand a crane. On the other side, it is located beside the main road in the factory area. If a lifting machine is used, it will affect the traffic of the entire factory area. Such tasks usually require a large amount of manpower and time as well as the continuous cooperation of lifting machinery. Because they are mostly working at heights, there are certain safety risks. During the installation process, the operators need to tie up on site, and then the lifting machinery is used to cooperate with loading, unloading, lifting and placing. It is not suitable to stack materials on the roof. Therefore, for projects with a large amount of roof panel construction work, the use of lifting machinery has a large number of working shifts, a large transportation volume, high construction costs and low efficiency.

[0004] At present, although the existing board lifting mechanisms can complete some tasks, there are still some defects:

[0005] 1) High construction cost. Due to the high working height of the multi-dimensional board roof and the fact that it is not suitable to stack materials on the roof, lifting machinery is often used in cooperation with manual labor for repeated lifting on site. For operations with a large factory building area, a large amount of multi-dimensional boards used on the roof and a large transportation volume, the use of lifting machinery has a large number of working shifts, increasing the construction cost.

[0006] 2) Low work efficiency. When lifting multi-dimensional boards, the ground operators need to continuously carry out tying operations, and only after fixing can they be lifted. The lifting speed of the lifting machinery is limited and there are many limiting conditions, which easily increases the construction period and the use of lifting machinery.

[0007] 3) Limited working range: Using lifting machinery to lift multi-dimensional boards is greatly restricted by the site. For many new projects, due to site restrictions, it is not suitable to carry out mechanical lifting operations, resulting in increased construction difficulty and increased construction cost. Content of the Utility Model

[0008] In order to solve the above technical problems, the utility model provides a self-loading and unloading multi-dimensional board clamping and lifting mechanism.

[0009] The technical solution of the utility model is realized as follows:

[0010] A self-loading and unloading multi-dimensional board clamping and lifting mechanism, comprising a support column, a lifting and hoisting arm, a balance beam and a board bracket. The lifting and hoisting arm is rotatably installed on the support column. The balance beam is suspended at one end of the lifting and hoisting arm. A pair of board brackets are provided at both ends of the balance beam, and the distance between the two paired balance beams is adjustable.

[0011] Further, the board bracket is in an "L" shape.

[0012] Further, a column is fixedly connected to the outer side surface of the board bracket. The distance between the two paired columns is adjustable, and the tops of the two paired columns are both suspended on the balance beam.

[0014] Further, a suspension chain is connected to the top end of the scissor-type adjusting beam, and the top end of the suspension chain is suspended at the bottom of the balance beam through a safety buckle.

[0015] Further, among the two paired columns, a limiting rod is rotatably connected to the inner side surface of one column through a limiting rod pin shaft. The end of the limiting rod away from the limiting rod pin shaft passes through the other column, and two positioning nuts are threadedly connected to the end of the limiting rod away from the limiting rod pin shaft. The two positioning nuts are respectively located on both sides of the column away from the limiting rod pin shaft.

[0016] Further, a gasket is provided between the positioning nut and the column away from the limiting rod pin shaft.

[0017] Further, inclined supports are fixedly provided on both sides of the column. The two inclined supports are symmetrically distributed on both sides of the column, and the bottom end of the inclined support is fixedly connected to the outer side surface of the board bracket.

[0018] Further, a lifting hook hole is provided at the top of the balance beam, and one end of the lifting and hoisting arm suspends the balance beam through the lifting hook hole.

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figures 1 to 3 shown, a self-loading and unloading multi-dimensional board clamping and lifting mechanism includes a support column 14, a lifting and hoisting arm 13, a balanced flat beam 7 and a plate bracket 1. The lifting and hoisting arm 13 is rotatably installed on the support column 14. The balanced flat beam 7 is suspended at one end of the lifting and hoisting arm 13. A pair of plate brackets 1 are provided at both ends of the balanced flat beam 7, and the distance between the two paired balanced flat beams 7 is adjustable.

[0030] Two pairs of plate brackets 1 support and fix the bottom surface of the multi-dimensional board at four positions, and by adjusting the distance between the paired plate brackets 1, the plate brackets 1 can stably clamp and fix the multi-dimensional board. Then, the multi-dimensional board is lifted from the ground material stacking place to the roof installation position by twisting and lifting the hoisting arm 13, so that the self-loading, unloading, hoisting and transportation work can be carried out in cooperation with manual operation without using a hoisting machine, realizing the loading, unloading, lifting and lowering of the multi-dimensional board.

[0031] The plate bracket 1 is in an "L" shape. The bottom edge of the plate bracket 1 supports on the bottom of the multi-dimensional board, and the side edge of the plate bracket 1 supports on the side of the multi-dimensional board, thereby improving the support and fixation effect on the multi-dimensional board.

[0032] A column 3 is fixedly connected to the outer side surface of the plate bracket 1. The distance between the two columns 3 distributed in pairs is set to be adjustable, and the tops of the two columns 3 in a pair are both suspended on the balance beam 7. The two columns 3 in a pair are in a parallel state, and the column 3 is vertically downward. In this way, the state of the plate bracket 1 is maintained by using the column 3, so that the plate bracket 1 can more stably support the bottom and side of the multi-dimensional board at the same time.

[0033] The top end of the column 3 is rotatably connected with a scissor-type adjusting beam 4. The two scissor-type adjusting beams 4 distributed in pairs are rotatably connected through an adjusting beam pin shaft 15. The top end of the scissor-type adjusting beam 4 is suspended on the balance beam 7. By rotating the two scissor-type adjusting beams 4 in a pair, the distance between the two columns 3 in a pair can be directly adjusted. Especially after the multi-dimensional board is lifted and suspended, by using the self-weight of the multi-dimensional board combined with the rotation of the two scissor-type adjusting beams 4, the plate bracket 1 automatically clamps the multi-dimensional board.

[0034] A suspension chain 5 is connected to the top end of the scissor-type adjusting beam 4. The top end of the suspension chain 5 is suspended at the bottom of the balance beam 7 through a safety lock 6. The setting of the safety lock 6 facilitates the connection and disconnection between the suspension chain 5 and the balance beam 7. By separating the suspension chain 5 from the balance beam 7 and then lifting the suspension chain 5, the column 3 and the plate bracket 1 make the scissor-type adjusting beam 4 rotate under the action of self-weight, and then the two columns 3 in a pair move closer to each other, which is more convenient for storage.

[0035] Among the two paired columns 3, one inner side of the column 3 is rotatably connected with a limit rod 10 through a limit rod pin shaft 9. One end of the limit rod 10 far from the limit rod pin shaft 9 passes through the other column 3, and two positioning nuts 11 are threadedly connected to one end of the limit rod 10 far from the limit rod pin shaft 9. The two positioning nuts 11 are respectively located on both sides of the column 3 far from the limit rod pin shaft 9. By rotating the positioning nuts 11, the distance between the two paired columns 3 is adjusted by the cooperation of the limit rod 10 and the positioning nuts 11. This can not only make the paired plate brackets 1 have a stable clamping effect on the multi-dimensional board, but also keep the columns 3 always in a vertical state, improving the clamping effect of the plate brackets 1 on the multi-dimensional board.

[0036] A gasket 12 is arranged between the positioning nut 11 and the column 3 far from the limit rod pin shaft 9. The gasket 12 can prevent the wear between the positioning nut 11 and the column 3. At the same time, it improves the clamping effect of the positioning nut 11 on the column 3.

[0037] Oblique supports 2 are fixedly arranged on both sides of the column 3. The two oblique supports 2 are symmetrically distributed on both sides of the column 3, and the bottom ends of the oblique supports 2 are fixedly connected to the outer side of the plate bracket 1. The two oblique supports 2 on the same side of the plate bracket 1 cooperate with the column 3 to form a triangular support, improving the stability of the plate bracket 1.

[0038] A lifting hook hole 8 is arranged at the top of the balance beam 7. One end of the lifting crane arm 13 suspends the balance beam through the lifting hook hole 8. By arranging the lifting hook hole 8, the lifting crane arm 13 can hook the lifting hook hole 8 through the hook and suspend the balance beam 7 on the lifting crane arm 13.

[0039] Among them, the rotation connection position between the lifting crane arm 13 and the support column 14 is located between the two ends of the lifting crane arm 13.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
