Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude transportation, and particularly relates to a conveying device that facilitates the up-and-down transportation of personnel and the transportation of materials to high places. Background Art

[0002] When performing high-altitude operations, one of the most commonly used conveying methods is to lower a safety rope from a high place, then a person fastens a safety belt and sets a sliding buckle on the safety belt, passes the safety rope through the sliding buckle, and then the person tightens the safety rope and relies on gravity to fall along the safety rope from a high place. When transporting materials, the same method of using a sliding buckle is adopted. The material is set on the safety rope through the sliding buckle, and then slides down along the safety rope through the self-weight of the material. This method can only transport downward and cannot transport upward.

[0003] In addition, there are some climbing devices for high-altitude operations. Although they can transport people or materials upward, their safety is not high, the machine structure is complex, and when problems and failures occur, the operators are likely to be trapped at a certain height in the air. When the operators are at a high place, these climbing devices cannot transport the materials at a low place to the operators at a high place in time. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and propose a conveying device to solve the technical problems mentioned in the background art, such as the complex structure of some climbing devices and the inability to transport the materials at a low place to the operators at a high place in time.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A conveying device includes a fixed pulley component, a cable, an anti-falling self-locking device, a safety belt, and a traction machine. The cable bypasses the fixed pulley component and its two ends hang down. One end of the cable passes through the anti-falling self-locking device and extends downward. The other end of the cable is fixedly connected to the anti-falling self-locking device, and the safety belt is arranged on the cable and close to this end of the cable. The traction machine is threaded on the cable and abuts against the anti-falling self-locking device to be used for pulling this end of the cable to descend, thereby driving the anti-falling self-locking device and the safety belt to rise synchronously, and for pulling this end of the cable to rise, thereby driving the anti-falling self-locking device and the safety belt to descend synchronously.

[0007] Working principle: Install the fixed pulley component at a high position. At this time, start the traction machine. The traction machine pulls this end of the cable to move upward. At this time, release the anti-falling self-locking device. The traction machine, the anti-falling self-locking device, and the safety belt descend synchronously until the traction machine and the safety belt descend to be close to the ground.

[0008] Then, the operator fastens the safety belt and places the material to be transported upward on the tractor. After that, the tractor is started again. The end of the cable towed by the tractor descends, and at the same time, the tractor pushes the anti-falling self-locking device to move upward along the cable. During the descent of this end of the cable, the other end of the cable starts to rise and drives the operator wearing the safety rope to rise synchronously. This process can transport the operator and the material upward simultaneously and synchronously, thus not only meeting the requirement of being able to transport people and materials upward, but also enabling the present invention to transport people and materials upward simultaneously and synchronously, so as to achieve the effect of transporting materials in a timely manner.

[0009] The beneficial effects of the present invention are as follows:

[0010] With the aid of the fixed pulley component, cable, anti-falling self-locking device, safety belt and tractor, the tractor is threaded on the cable and abuts against the anti-falling self-locking device, and can be used to tow one end of the cable provided with the anti-falling self-locking device to descend, thereby driving the anti-falling self-locking device and the safety belt to rise synchronously. The tractor can also tow one end of the cable provided with the anti-falling self-locking device to rise, thereby driving the anti-falling self-locking device and the safety belt to descend synchronously, so that people and materials can be transported up and down.

[0011] In addition, the present invention can transport people and materials to high altitudes simultaneously, so that the materials can be transported to high places in a timely manner. The present invention only relies on the fixed pulley component, cable, anti-falling self-locking device, safety belt and tractor, and the overall processing and manufacturing cost is relatively low. Only by starting the tractor can the simultaneous and synchronous transportation of people and materials be realized, with simple operation and high transportation efficiency.

[0014] Description of the reference numerals: fixed pulley component 1, cable 2, anti-falling self-locking device 3, safety belt 4, mounting shell 5, moving component 6, annular groove 7, worm 8, rotating shaft 9, turbine 10, observation hole 11, hook 12. Detailed Embodiments

[0015] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0016] As Figure 1As shown in the figure, a conveying device includes a fixed pulley component 1, a cable 2, an anti-falling self-locking device 3, a safety belt 4, and a tractor. The cable 2 bypasses the fixed pulley component 1 and its two ends droop. One end of the cable 2 passes through the anti-falling self-locking device 3 and extends downward. The other end of the cable 2 is fixedly connected to the anti-falling self-locking device 3, and the safety belt 4 is arranged on the cable 2 and close to this end of the cable 2. The tractor is threaded on the cable 2 and abuts against the anti-falling self-locking device 3 to be used for pulling this end of the cable 2 to descend, thereby driving the anti-falling self-locking device 3 and the safety belt 4 to rise synchronously, and for pulling this end of the cable 2 to rise, thereby driving the anti-falling self-locking device 3 and the safety belt 4 to descend synchronously.

[0017] The present invention can simultaneously transport personnel and materials to high altitudes, and can also separately transport materials to high places in time for operators. The present invention only relies on the fixed pulley component 1, the cable 2, the anti-falling self-locking device, the safety belt 4, and the tractor. The overall processing and manufacturing cost is relatively low. Only by starting the tractor can the simultaneous and synchronous transportation of personnel and materials be realized. The operation is simple, the transportation efficiency is high, and the safety factor of the staff can be doubled.

[0018] As Figure 1 and Figure 2 shown in the figure, the tractor includes an installation shell 5, a driving component, and two rows of moving components 6 arranged on the installation shell 5. The driving component is arranged on the installation shell 5 and is used for driving the two rows of moving components 6 to move along the cable 2. The end of the cable 2 passes through the gap between the two rows of moving components 6, and the cable 2 abuts against each moving component 6 to rise or fall as the moving component 6 moves. The two rows of the moving components 6 are two rows of opposite pressing wheels, and the rotation directions of the two rows of the moving components 6 are opposite to rotate and move along the cable 2. A hook 12 is fixed on the installation shell 5 of the tractor. Through the hook 12, operators can more conveniently hang materials on the installation shell 5 through the hook 12. This method can improve the efficiency of placing materials. The driving component is arranged on the installation shell 5 and is used for driving the two rows of moving components 6 to rotate.

[0019] As Figure 2 shown in the figure, a ring groove 7 coaxial with each moving component 6 is formed on the wheel surface of each moving component 6. The cable 2 passes through the gap between the two rows of opposite ring grooves 7, and the cable 2 abuts against each ring groove 7. Passing the cable 2 through the ring groove 7 can thoroughly ensure the passing position of the cable 2 between the two rows of moving components 6. Thus, the ring groove 7 plays a guiding role in the vertical movement of the cable 2, and thoroughly ensures that the cable 2 continuously passes through the ring groove 7. This method ensures safety during the operation process.

[0020] As Figure 1 and Figure 2As shown in the figure, the driving component includes a worm 8 penetrating through the mounting shell 5 and a connecting component. The connecting component is arranged between the worm 8 and two rows of moving components 6 to drive the two rows of moving components 6 to rotate as the worm 8 rotates. The connecting component includes two rows of rotating shafts 9 penetrating through the mounting shell 5. A turbine 10 meshing with the worm 8 is fixedly sleeved on each row of rotating shafts 9. The two rows of moving components 6 are respectively fixedly connected to the two rows of rotating shafts 9. The cable 2 penetrates through the mounting shell 5 and passes between the two rows of moving components 6. A motor is arranged on the mounting shell 5. The worm 8 is driven to rotate by the motor. The rotation of the worm 8 drives the two rows of rotating shafts 9 to rotate. The two rows of rotating shafts 9 drive the two rows of moving components 6 to rotate in opposite directions. During the forward or reverse rotation of the moving components 6 relative to the cable 2, the cable 2 can be driven to move downward or upward, thereby realizing the lifting or lowering process of the cable 2. This manufacturing method of the driving component not only has a simple structure and low manufacturing cost, but also has a simple working process and is convenient for operation. And when it is necessary to replace or add substances, the tractor can move up and down independently along the cable 2, and then transport the substances at a low place to a high place.

[0021] Meanwhile, when the personnel are transported to a certain height, the operators need to work at this height position. At this time, the tractor can be started. The tractor moves downward along the cable 2, and then drives the hook 12 to move downward. When the hook 12 moves close to the ground, the operators on the ground hang the substances on the mounting shell 5 of the tractor through the hook 12. Then, the tractor is started again. The moving components 6 of the tractor rise along the cable 2, so that the transported substances can be transported to the side of the operators at a high place, which is more convenient for the operators to work at a certain height range and improves the applicability of the present invention.

[0022] As Figure 1 and Figure 2 shown in the figure, the two rows of moving components 6 are both located outside the mounting shell 5. Strip-shaped observation holes 11 are opened on the mounting shell 5 at positions corresponding to the two rows of moving components 6. The wear degree of the turbines 10 and rotating shafts 9 inside the mounting shell 5 can be observed through the observation holes 11, so as to replace the turbines 10 and rotating shafts 9 in time. The fixed pulley component 1 is a reciprocating descender, and the reciprocating descender can reduce the moving speed of the cable 2 rising or falling, thereby further ensuring the safety of the entire transportation operation process.

[0023] It also includes a wireless remote controller for controlling the tractor to move up and down along the cable 2. A controller is built in the tractor. Instructions are exchanged between the wireless remote controller and the controller, so as to remotely control the tractor to move up and down along the cable 2.

[0024] Working principle: Install the fixed pulley component 1 at a high position. At this time, start the tractor through the motor. The moving component 6 of the tractor moves downward along the cable 2. At this time, this end of the cable 2 starts to move upward. Then release the anti-falling self-locking device 3. The tractor and the anti-falling self-locking device 3 start to descend. The end of the cable 2 with the anti-falling self-locking device 3 moving upward will drive the other end of the cable 2 to descend. At this time, the safety belt 4 near the end of the cable 2 starts to descend until the tractor and the safety belt 4 descend close to the ground.

[0025] Then the operator fastens the safety belt 4 and places the material to be transported upward on the hook 12 on the mounting shell 5. After that, start the motor again through the wireless remote control. The motor drives the worm 8 to rotate again. Then the worm 8 drives the turbine 10 to rotate. The turbine 10 then drives the two rows of moving components 6 to rotate. The two rows of moving components 6 start to climb along the cable 2. At this time, this end of the cable 2 starts to descend. And at the same time, the ascending tractor pushes the anti-falling self-locking device 3 to move upward along the cable 2. During the descent of this end of the cable 2, the other end of the cable 2 starts to rise and drives the operator wearing the safety belt 4 to rise synchronously. This process can transport the operator and the material upward simultaneously and synchronously, thus not only meeting the requirement of being able to transport people and materials upward, but also enabling the present invention to transport people and materials upward simultaneously and synchronously, so as to achieve the effect of transporting materials in a timely manner.

[0026] And when the operator is transported to a certain height, the operator needs to work at this height position. At this time, the anti-falling self-locking device 3 can control the cable 2 to prevent the cable 2 from moving. At this time, the tractor can be started through the wireless remote control. The moving component 6 of the tractor moves downward along the cable 2, and then drives the hook 12 to move downward. When the hook 12 moves close to the ground, the operator on the ground hangs the material on the mounting shell 5 of the tractor through the hook 12. Then start the tractor again through the wireless remote control. The moving component 6 of the tractor moves upward along the cable 2, so that the transported material can be transported to the side of the operator at a high position, which is more convenient for the operator to perform high-altitude operations within a certain height range and improves the applicability of the present invention.
