Description

Technical Field

[0001] The present invention relates to the technical field of material transportation, and particularly to a material transportation device for construction sites during construction. Background Art

[0002] Construction is the production activity in the implementation stage of project construction, which is the construction process of various buildings. It can also be said that at a designated location, people use various building materials and construction machinery and equipment to carry out production activities for building various building products within a certain space and time according to a specific design blueprint.

[0003] During the construction of high-rise buildings, workers need to perform construction operations on a pre-erected workbench or construction platform. Therefore, additional workers need to be arranged to load materials under the construction platform, and then transport the material buckets filled with materials to the lifting equipment. The lifting equipment then lifts the materials to a position near the construction platform for the construction workers to use. For example, the Chinese invention patent with the publication number CN114920175A proposes a high-altitude material transportation device for construction projects. This device places the materials on a loading plate and then transports the materials to a high altitude through a lifting mechanism. The above-mentioned devices all require additional construction workers to monitor the material transportation process under the construction platform, or require construction workers to participate in part of the transportation work (such as transporting empty material buckets to the loading area, transporting material buckets filled with materials to the lifting area, etc.). This requires a lot of labor. Therefore, how to design a more automated material transportation device that requires less labor has become an urgent issue to be solved. Summary of the Invention

[0004] The purpose of the present invention is to provide a material transportation device for construction sites during construction. The present invention can more automatically realize the loading and transportation of materials, without the need to arrange additional workers to participate or monitor, thus saving labor.

The inlet of the conveying pipe extends above the construction platform, and the outlet of the conveying pipe is arranged directly opposite the placing mechanism; A conveyor belt for transporting material buckets is arranged on one side of the placing mechanism. A mixing tank is erected on the upper side of the conveyor belt, and a placing table is arranged on one side of the conveyor belt; The conveying device further includes a mounting frame arranged on the construction platform. A wire winding machine is arranged on one side of the mounting frame. A guiding rope is wound on the wire winding machine. One end of the guiding rope extends out along the front of the mounting frame and is fixed on the ground; An electric wire winding machine is arranged on the mounting frame. A suspension cable is wound on the electric wire winding machine. The end of the suspension cable is connected with a sliding sleeve. The sliding sleeve is sleeved on the guiding rope, and a hook is arranged on the lower side of the sliding sleeve.

[0006] In the aforesaid construction material conveying device for a construction site, the placing mechanism includes a base. A rotating shaft is arranged on the base. Two blocking plates are arranged on the rotating shaft. Notches are arranged on the sides of the blocking plates; A driving device connected to the rotating shaft is arranged on the side of the base; An arc-shaped guiding rod is further arranged on the upper side of the base, and the guiding rod is located on both sides of the blocking plates;

[0007] When the blocking plate rotates to the upper side, the blocking plate can block the outlet of the conveying pipe and prevent the material bucket from falling. When the blocking plate no longer blocks the outlet of the conveying pipe, the material bucket at the outlet of the conveying pipe can fall between the two guiding rods and stay on the guiding rods temporarily. When the inner wall of the notch of the blocking plate contacts the material bucket, the blocking plate continues to rotate, and the inner wall of the notch will push the material bucket to slide along the guiding rod and finally place the material bucket on the conveyor belt.

[0008] In the aforesaid construction material conveying device for a construction site, a step is arranged on the side of the placing table directly opposite the conveyor belt, and the bottom surface of the step is flush with the upper surface of the conveyor belt;

[0009] The conveyor belt transports the material bucket to the step and makes the material bucket contact the inner wall of the step. Other material buckets are blocked by the material bucket in front and will stay on the conveyor belt temporarily until the hook hooks away the material bucket on the step, and then the material bucket behind will continue to move to the step.

[0010] In the aforesaid construction material conveying device for a construction site, the wire winding machine includes a mounting seat. A driving shaft is arranged on the mounting seat. A driving gear is arranged on the driving shaft; A driven shaft is further arranged on the mounting seat. A driven gear meshing with the driving gear is arranged on the driven shaft. A wire winding roller is arranged in the middle of the driven shaft; A handle is arranged at the end of the driving shaft. A ratchet is arranged on the driving shaft. A pawl cooperating with the ratchet is arranged on the mounting seat.

[0011] In the aforesaid construction material conveying device for a construction site, the diameter of the driving gear is smaller than that of the driven gear.

[0012] In the aforesaid construction site construction material conveying device, a plurality of fixed pulleys are provided on the mounting frame, the guiding rope is wound around the winding roller of the wire winding machine through the fixed pulleys, and the sling is wound around the electric wire winding machine through the fixed pulleys.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the material bucket is placed into the conveying pipe, and the material bucket is placed on the conveyor belt through the placing mechanism. After the material is loaded into the mixing tank, the material bucket is conveyed to the placing table. The electric wire winding machine is started, the sliding sleeve is pulled to move upward along the guiding rope, the hanging hook is driven to move upward, the hanging hook hooks the material bucket and lifts the material bucket upward for transportation. When the material bucket moves above the construction platform, the wire winding machine is adjusted to make the guiding rope gradually slack. Under the combined action of gravity and the pulling force of the sling, the material bucket gradually approaches the construction platform, and finally the construction worker removes the material bucket. Through the above process, the functions of material loading and transportation can be realized, and there is no need to arrange additional workers to guard or participate in the work under the construction platform during the whole process, which is more automated and saves labor.

[0015] 2. In the present invention, when the material bucket moves above the construction platform, the winding roller is rotated by turning the handle to make the guiding rope gradually slack. In cooperation with the gravity of the material bucket and the pulling force of the sling, the material bucket gradually approaches the construction platform, which is convenient for the worker to take the material bucket.

[0016] 3. In the present invention, when the blocking plate of the placing mechanism rotates to the upper side after the material bucket falls from the conveying pipe, it can prevent the material bucket from falling from the outlet of the conveying pipe. When the blocking plate no longer blocks the outlet of the conveying pipe, the material bucket can fall between the two guiding rods. After the notch of the blocking plate contacts the material bucket, it can push the material bucket to slide along the guiding rods and finally place the material bucket on the conveyor belt, without manually placing the material bucket, which is convenient for loading materials.

[0017] 4. In the present invention, steps are provided on the surface of the placing table. After the material bucket is conveyed to the placing table, it will be blocked by the inner wall of the step and stop moving. The material bucket behind will be blocked by the material bucket in front and temporarily stay at the outlet of the conveyor belt until the material bucket in front is lifted by the hanging hook, and then the material bucket behind will continue to move forward, so as to realize the orderly conveying of the material buckets.

As shown in the attached Figure 7 figure, when the blocking plate 23 no longer blocks the outlet of the conveying pipe 11, the material bucket at the outlet of the conveying pipe 11 can fall between the two guide rods 25 and stay on the guide rods 25 temporarily. When the inner wall of the notch 24 of the blocking plate 23 contacts the material bucket, the blocking plate 23 continues to rotate, and the inner wall of the notch 24 will push the material bucket to slide along the guide rods 25 and finally place the material bucket on the conveyor belt 10.

[0028] A mixing tank 9 is installed on the upper side of the conveyor belt 10. The operation of the conveyor belt 10 can be controlled by a preset program or rule, so that when the material bucket on the conveyor belt 10 moves below the mixing tank 9, the conveyor belt 10 temporarily stops conveying, and the mixing tank 9 can be started to fill the material into the material bucket. After the material in the material bucket is filled, the mixing tank 9 is closed, and the conveyor belt 10 continues to work to convey the material bucket. A placing table 26 is arranged on one side of the conveyor belt 10. A step 28 is arranged on the side of the placing table 26 facing the conveyor belt 10, and the bottom surface of the step 28 is flush with the upper surface of the conveyor belt 10; the conveyor belt 10 transports the material bucket to the step 28 and makes the material bucket contact the inner wall of the step 28. Other material buckets will be blocked by the front material bucket and stay on the conveyor belt 10 temporarily until the hook 27 hooks away the material bucket on the step 28, and then the rear material bucket will continue to move to the step 28.

[0029] The conveying device further includes a mounting rack 4 arranged on the construction platform 1. A wire winding machine 2 is arranged on one side of the mounting rack 4.

[0030] Working principle: put the material barrel with fixed handle into the conveying pipe 11, and after the material barrel falls from the conveying pipe 11, it is straightened by the placing mechanism 8 and placed on the conveyor belt 10. The conveyor belt 10 transfers the material barrel to the bottom of the mixing tank 9 to fill the material, and then transfers the material barrel filled with material to the placing table 26, and makes the material barrel located in the step 28; start the electric winding machine 5, wind the sling 6 on the electric winding machine 5, thereby pulling the sliding sleeve 7 upward, and the sliding sleeve 7 hooks the handle of the material barrel through the hook 27, driving the material barrel to move upward together. When the height of the material barrel is higher than the construction platform 1, adjust the twisting machine 2 to make the guide rope 3 gradually loosen. Since the electric winding machine 5 is still working, the material barrel will gradually approach the construction platform and pull the guide rope 3 to bend the guide rope 3. When the material barrel moves to a position that is convenient for workers to reach or take, turn off the electric winding machine 5, stop adjusting the twisting machine 2, and the worker removes the material barrel from the hook 27. After the material in the material barrel is used up, the empty material barrel is put into the entrance of the conveying pipe 11, and the material barrel falls along the conveying pipe 11, and the above process is repeated, thereby realizing the function of filling materials and transporting them. Moreover, during the entire material filling and transportation process, there is no need to arrange additional workers to supervise the transportation process under the construction platform 1, which saves labor.

[0031] During the above transportation process, the adjustment process of the stranding machine 2 is as described below: When the material bucket moves above the construction platform 1, rotate the pawl 20 so that the pawl 20 disengages from the ratchet wheel 19, and then rotate the handle 12 to drive the rotation of the driving shaft 14. The driving shaft 14 drives the rotation of the driven shaft 15 through the driving gear 18 and the driven gear 16, thereby driving the rotation of the stranding roller 17, causing the guide rope 3 to be released from the stranding roller 17, and the guide rope 3 gradually becomes slack. After the material bucket is removed, rotate the handle 12 in the reverse direction to drive the reverse rotation of the stranding roller 17, wind the guide rope 3 onto the stranding roller 17 until the guide rope 3 is in a taut state, stop rotating the handle 12 and lock the ratchet wheel 19 with the pawl 20.
