Description

Technical Field

[0001] The present invention relates to the technical field of building construction equipment, in particular to an anti-shake material hoist. Background Art

[0002] During building construction, due to limited manpower, in order to improve work efficiency, motor-driven hoists are often needed to transport building materials or material packages. Hoists are generally divided into crawler-type and ordinary crane-type hoists. Cranes generally extend or retract cables driven by motors and use hooks or grab plates equipped with hooks to transfer materials. However, existing equipment of this type still has the following problems in actual use:

[0003] Since the materials that need to be hoisted are often heavy, the single hook structure will cause the materials to shake due to the shift of the center of gravity and the movement during the material transfer process, which is not only easy to fall but also easy to affect the construction space. Although there are hanging basket-type hoists in the existing technology and they are combined with bottom counterweights to achieve smooth transfer of materials, the hanging basket itself has a large demand on the volume of the materials, and the transfer of the materials themselves in the hanging basket is also very troublesome. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-shake material hoist to solve the problem raised in the above background technology that the materials that need to be hoisted are often heavy, so the single hook structure will cause the materials to shake due to the center of gravity offset and movement during the material transfer process, which is not only easy to fall but also easy to affect the construction space. Although there are hanging basket-type hoists in the prior art and they are combined with bottom counterweights to achieve smooth transfer of materials, the hanging basket itself has a large demand on the volume of the materials, and the transfer of the materials themselves in the hanging basket is also a very troublesome problem.

[0006] Preferably, the hoist also includes a limiting device, which is arranged above the grab plate and is used to limit the lifting rope and prevent the single-strand rope from shaking during the process of lifting materials.

[0007] Preferably, the rope is an elastic tubular structure with a cavity inside. The cavity is connected to the air holes opened on the left and right side walls of the rope. The top of the cavity is connected to the connecting device, and the connecting device supplies air through the air supply device, so that the air flow is blown out toward the outer surface of the material through the cavity and the air holes.

[0008] Preferably, the communication device includes an air cavity, the lower half of the air cavity provided inside the grab plate is connected to the cavities in the ropes distributed at equal angles, and the top of the air cavity is connected to the air supply device.

[0009] Preferably, the air supply device includes a flexible air pipe and an air pump, the bottom end of the air pipe is fixed on the gripping plate and is connected to the top of the cavity, and the middle section of the air pipe slides through the stabilizing plate and is connected to the frame and the air pump.

[0010] Preferably, a partition in a sealed fixed grab plate is provided inside the air cavity, and the partition divides the air cavity into two spaces, the lower space is connected to the rope, and the upper space is connected to the air pipe and the limit device. The upper and lower spaces are connected through a one-way hole provided on the partition.

[0011] Preferably, the limiting device is a flexible tube body wrapped around the outside of the lifting rope, the top end of the flexible tube body is sealed and fixed to the lower end surface of the stabilizing plate, and the bottom end is fixed to the upper end surface of the grabbing plate, and the space between the tube body and the section of the lifting rope is connected to the air cavity.

[0012] Preferably, the outer surface of the tube body is provided with horizontally distributed folds at equal vertical intervals, a magnetic sheet is provided between two adjacent folds, and the outer surfaces of the upper and lower adjacent magnetic sheets are arranged to attract each other.

[0013] Preferably, the limiting device is a sling body, which includes an external wear-resistant braided layer and an internal flexible sealing tube. A metal mesh is provided between the sealing tube and the braided layer to enhance the structural strength of the sling. The three are fixedly connected, and the inflated sealing tube constitutes the limiting device.

[0014] Preferably, the bottom end of the sealing tube is connected to the air cavity space above the partition, and two upper and lower adjacent extrusion shafts are provided inside the end of the top crossbeam part of the frame.

At the same time, the same power source can be used to avoid the shaking of the rope body itself caused by transferring materials, and the anti-shake effect is significant and the device is very simple and durable.

[0017] 1. The structural design of the rope and the barb can, on the one hand, use the downward drag force of the counterweight ball to prevent the material from shaking, and on the other hand, use the barb to effectively block the material with a falling tendency, and the anti-fall effect is more significant;

[0018] Furthermore, the structural design of the air holes and internal cavity on the rope not only enables the rope to be anti-shake and anti-fall, but also uses the air supply of the air pipe and air cavity to clean dust on the top and sides of the material, making it more functional.

[0019] 2. The use of the limiting device composed of a tube body can stably limit the vertical part of the rope, effectively preventing the rope from shaking. At the same time, it can minimize the impact on the space and the winding of the rope by self-compression and deformation;

[0020] Furthermore, the structural design of the lifting rope composed of a sealing tube and a metal mesh not only has the advantage of utilizing airflow to completely prevent the lifting rope from shaking, but also can completely avoid occupying the upward movement space of the hook when the lifting rope itself is wound up, and at the same time will not limit the downward movement length of the lifting rope and the hook. Moreover, the structural design of the partition and the one-way hole can ensure that the airflow from the same air source can make the airflow blown out of the rope in a high-pressure state while ensuring the normal use of the limit device, thereby further improving the cleaning effect.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-8 , the present invention provides the following technical solutions:

[0032] Example 1:

[0033] In this embodiment, in order to prevent the material bag from shaking and swinging at the bottom of the hook, the technical problems existing in the prior art are solved. Figure 1The lifting mechanism is a kind of lifting mechanism that is housed in the lifting platform, and the lifting mechanism is a kind of lifting mechanism that is housed in the lifting platform, and the lifting mechanism is a kind of lifting mechanism that is housed in the lifting platform, and the lifting mechanism is a kind of lifting mechanism that is housed in the lifting platform. The other motors installed in the machine drive the frame 1 to rotate so that the material is transferred to the specified position and height. Before this, the user can first place the ropes 6 on the outer surface of the material bag, and because the top of the rope 6 is fixed to the side surface of the grab plate 3, the middle section of the rope 6 is stretched by the surface of the material, and the rope 6 itself will exert pressure on the material toward the central axis of the grab plate 3 under the influence of the counterweight ball 8, thereby effectively preventing the material from shaking under the hook. At the same time, since the inner wall of the rope 6, that is, the side in contact with the outer wall of the material, is provided with barbs 7 distributed obliquely upward, the barbs 7 can be a hard structure with a sharp surface, or an elastic material such as high-damping rubber. Under the influence of several barbs 7, the connection between the hanging rope 2 and the material can be tighter, effectively alleviating the downward trend of the material itself due to gravity. Even in the case of decoupling, the material will not fall quickly and directly, which can play a good protective role.

[0034] Example 2:

[0035] At the construction site, a lot of dust is likely to remain on the outer surface of the material packaging or the material itself. During the transportation process, the material is likely to come into contact with other parts, causing the dust and dirt to be transferred and spread. Manual wiping or cleaning will greatly reduce the efficiency. Therefore, in order to solve this problem, the following solution is also disclosed in this embodiment. Specifically, Figure 1-3As shown, the rope 6 is elastic and has a tubular structure with a cavity 10 inside. The cavity 10 is connected to the air holes 9 opened on the left and right side walls of the rope 6. The top of the cavity 10 is connected to the connecting device. The connecting device supplies air through the air supply device, so that the air flow is blown out toward the outer surface of the material through the cavity 10 and the air holes 9. The connecting device includes an air cavity 11. The lower half of the air cavity 11 opened inside the grab plate 3 is connected to the cavity 10 in the rope 6 distributed at equal angles, and the top of the air cavity 11 is connected to the air supply device. The air supply device includes a flexible air pipe 12 and an air pump 21. The bottom end of the air pipe 12 is fixed on the grab plate 3, and the air pipe (12) is connected to the top of the cavity 10. The middle section of the air pipe (12) slides through the stabilizing plate 5 and is connected to the frame 1 and the air pump 21. During the transportation and the process of overlapping the rope 6 on the surface of the material, the air pump 21 can operate accordingly, and the air flow enters through the air pipe 12. Figure 3 The air flows into the air cavity 11 shown in the figure, and then enters the interior of the cavity 10 and is ejected from the air hole 9. Since the air hole 9 is opened on the side of the rope 6, the air flow will be sprayed on the side and top surface of the material in a correspondingly larger range, thereby achieving the corresponding purpose of cleaning the surface of the material.

[0036] In the prior art, in order to ensure that the rope structure does not shake during the process of lifting and transporting materials, multiple ropes are generally used for lifting operations. However, when multiple ropes are actually used, they not only occupy too much space for the winding rollers, but are also very likely to cause serious wear. The use of a rigid structure that can be extended up and down will result in a limited lifting space for the material and increase the vertical space occupied by the hoist. Therefore, in order to solve this technical problem, the following solution is disclosed in this embodiment, specifically as follows: Figure 4As shown, a partition 13 in a sealed fixed grab plate 3 is provided inside the air cavity 11, and the partition 13 divides the air cavity 11 into two spaces, the lower space and the sling rope 6, and the upper space is connected to the air pipe 12 and the limiting device. The upper and lower spaces are connected through a one-way hole 14 provided on the partition 13. At the same time, the elevator also includes a limiting device, which is provided above the grab plate 3 and is used to limit the lifting rope 2 and prevent the single-strand rope body from shaking during the process of lifting materials. The limiting device is a flexible tube body 15 wrapped around the outside of the lifting rope 2. The top end of the flexible tube body 15 is sealed and fixed to the lower end face of the stabilizing plate 5, and the bottom end is fixed to the upper end face of the grab plate 3, and the space between the tube body 15 and the section of the lifting rope 2 is connected to the air cavity 11. The outer surface of the tube body 15 is provided with horizontally distributed folds at equal vertical intervals, and there is a fold between two adjacent folds. The outer surfaces of the two adjacent magnetic sheets 16 above and below are arranged to attract each other. After the air pump 21 delivers the airflow to the inside of the air cavity 11 through the air pipe 12, the airflow will first enter the tube body 15 and expand the tube body 15 by inflation, so that the stabilizing plate 5 and the grabbing plate 3 are in a relatively rigid connection state. After reaching the threshold, the subsequent filling or the rising of the material causes the tube body 15 to be vertically compressed and deformed along the fold. The gas generated will pass through the one-way hole 14 into the space below the partition 13. Therefore, the airflow filled under the partition 13 is a high-pressure airflow with a faster flow rate. In this way, after the airflow is blown out through the air hole 9, the cleaning effect it can achieve is better. The use of the magnetic sheet 16 is to ensure that the compressed tube body 15 can be in a relatively stable and non-deformable state, to ensure that the sling 2 will not swing at will during the material transportation process.

[0037] Example 3:

[0038] Unlike the above embodiment, the limiting device in this embodiment is the hanging rope 2 itself. Because after adopting the technical solution of the first embodiment, the tube body 15 is fixedly connected to the grab plate 3 and the stabilizing plate 5, so when the storage device or the material moves upward, the grab plate 3 moves upward, and the tube body 15 that is folded and compressed by force still occupies a certain space. Therefore, in order to solve this problem, different technical solutions are disclosed in this embodiment, specifically as follows: Figure 5-8As shown, the difference from the second embodiment is that the limiting device is the main body of the rope 2, the rope 2 includes an external anti-wear braided layer and an internal flexible sealing tube 18, and a metal mesh 17 for strengthening the structural strength of the rope 2 is provided between the sealing tube 18 and the braided layer. The three are fixedly connected, wherein the inflated sealing tube 18 constitutes the limiting device, and the bottom end of the sealing tube 18 is connected to the air cavity 11 above the partition 13. In addition, two upper and lower adjacent extrusion shafts 19 are provided inside the end of the top crossbeam of the frame 1, and the extrusion shaft 19 is rotatably mounted on the upper and lower ends of the extrusion shafts 19. In the frame 1, the spacing between the two extrusion shafts 19 coincides with the thickness of the rope body 2 after being compressed to its limit, and the rope body 2 passes between the two extrusion shafts 19. A guide cylinder 20 is also installed in the frame 1. The guide cylinder 20 is vertically fixed on the frame 1 on the side of the extrusion shaft 19. At the same time, the guide cylinder 20 is vertically movable through the suspension rope 2. The airflow filled into the air pipe 12 first directly enters the interior of the sealing tube 18. Therefore, the sealing tube 18 filled with high-pressure gas drives the inflated suspension rope 2 as a whole to be in a state that is not easy to bend, and this state that is not easy to bend will last until Figure 8 At the extrusion shaft 19 shown, under the dual limiting guidance of the guide cylinder 20 and the stabilizing plate 5, the lower half of the sling rope 2 is ensured not to shake due to the transfer of the material, ensuring that the material can move smoothly and the height can be adjusted. At the same time, in the process of the sling rope 2 being wound, the upward movement of the grab plate 3 is no longer restricted by the occupied space. At the same time, the extrusion shaft 19 will also squeeze out the high-pressure airflow in the sling rope 2 and flow downward from the one-way hole 14.
