A lifting device for building construction materials

Abstract

The present invention discloses a lifting device for building construction materials, comprising: a placing seat, a supporting frame fixedly installed on the placing seat, a winch fixedly connected to the supporting frame, and an oil guide pipe, so that two arc blocks can be effectively oiled when they are in contact with the lifting rope, thereby reducing the friction between the lifting rope and the pulley on the supporting frame when the lifting rope is retracted, and can remove dust and debris on the surface of the lifting rope, thereby effectively avoiding the phenomenon of rope jamming that may occur during the lifting process of the small crane. The fundamental reason for the rope jamming is that dust will adhere to the surface of the lifting rope during the process of the small crane lifting the heavy object, and combined with the construction environment, the friction between the lifting rope and the pulley will increase, which may cause the rope surface to become rough, thereby increasing the friction between the pulley and the lifting rope, which may cause plastic deformation or rope breakage when the rope is bent, thereby effectively improving the stability of the building construction material lifting device during use.

Description

Technical Field

[0001] The invention relates to the technical field of building construction material lifting equipment, in particular to a building construction material lifting device. Background Art

[0002] Housing construction refers to the construction of houses or other buildings on land where infrastructure construction is completed. It covers the construction of residential buildings, industrial plants, commercial buildings, office buildings, and other special buildings. Infrastructure covers transportation and airports, bridges and ports, communications, water conservancy, urban water supply, drainage, gas supply, power supply facilities, and fixed asset construction required to provide intangible products or serve science, education, culture, health and other units.

[0003] When low-rise buildings are under construction, small cranes are placed on the roof of the construction site. Small cranes are also called hoists, small hoists, and portable hoists. They are small mechanical equipment with excellent performance and extremely wide applications. They are suitable for hoisting operations in high-rise buildings, such as the hoisting of various building materials and various decorative materials, especially for long and wide materials such as wooden boards and woodworking boards that are inconvenient to carry in corridors. At the same time, they can also be used for lifting large workpieces on and off machine tools in mechanical processing workshops, home appliance factories, production assembly lines in food factories, warehouses, and household lifting items.

[0004] When it is necessary to move materials, a small building crane can be placed on the roof of the construction site. After placement, when it is necessary to transport building materials, the construction workers on the roof can slowly lower the hook on the small crane from the roof through the rope. After lowering, the construction workers downstairs can connect the trolley loaded with cement and bricks with the hook on the small crane. When the rope of the construction workers downstairs is connected to the hook, the construction workers on the roof will start the small crane, so that the trolley loaded with cement and bricks will slowly rise, thereby transporting materials to the construction workers on the roof. However, the rope may get stuck during the lifting process of the small crane. The fundamental reason for the rope getting stuck is that dust will adhere to the surface of the rope when the small crane is lifting heavy objects, and combined with the construction environment, the friction between the rope and the pulley will increase, which may cause the rope surface to become rough, which will increase the friction between the pulley and the rope, and may cause plastic deformation or rope breakage when the rope is bent.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1-10The present invention provides a technical solution: a building construction material lifting device, comprising: a placing seat 1, a supporting frame 2 is fixedly installed on the placing seat 1, a winch 3 is fixedly connected to the supporting frame 2, a lifting rope 4 is connected between the winch 3 and the supporting frame 2, a hook 5 for hanging building construction materials is installed on the other end of the lifting rope 4, a lubrication component 6 for lubricating the lifting rope 4 is arranged between the lifting rope 4 and the supporting frame 2, an oil injection component 8 for injecting oil into the lubrication component 6 is arranged between the lubrication component 6 and the supporting frame 2, and a transmission component 7 for transmitting oil injection power to the oil injection component 8 is arranged between the oil injection component 8 and the winch 3. When the construction workers use the building construction material lifting device, they can start the winch 3 first, so that the lifting rope 4 starts to be released and the hook 5 starts to descend. When the winch 3 is lowered, the lifting rope 4 starts to be released and the hook 5 starts to descend. When the winch 3 is started, the pulley 1 71 is rotated, and the pulley 2 74 is rotated to drive one of the pulleys 3 77 to rotate, and the pulley 4 78 is combined with one of the transmission belts 2 79 to drive the connected pulley 5 710 to rotate. When one of the pulleys 5 710 rotates, it is combined with one of the transmission belts 3 714 to rotate one of the pulleys 6 713, so that one of the bevel gears 1 715 drives the bevel gear 2 716 to rotate, so that one of the spur gears 1 718 drives the toothed rod 719 to shift, and when one of the toothed rods 719 shifts, one of the spur gears 2 721 is rotated, so that the diamond block 723 is rotated, so that The two side blocks 65 start to move in opposite directions, combined with the connecting seat 64, so that the two arc blocks 63 are separated from the lifting rope 4, which effectively avoids the friction caused by the contact between the lifting rope 4 and the arc block 63 from affecting the speed of releasing the lifting rope 4, so that the material lifting device for building construction is more convenient to release the rope. When the material is hung and lifted, the winch 3 can be reversed, so that the lifting rope 4 starts to be wound, so that the position of the hook 5 starts to rise. When the winch 3 is reversed, the pulley 1 71 is rotated. Combined with the pulley 1 71, the pulley 3 77 and the transmission rod 1 73 are connected in a ratchet manner, and the connection methods on both sides are opposite. Therefore, when the pulley 2 74 rotates, it drives the other pulley 3 77 to rotate. Combined with the other The transmission belt 2 79 makes another pulley 4 78 drive the connected pulley 5 710 to rotate. When the other pulley 5 710 rotates, it combines with another transmission belt 3 714 to make another pulley 6 713 rotate, so that another bevel gear 1 715 drives bevel gear 2 716 to rotate, so that another spur gear 1 718 drives the toothed rod 719 to move and reset. When the other toothed rod 719 is reset, another spur gear 2 721 is rotated, so that the diamond block 723 rotates and resets. Combined with the spring 1 68 and the telescopic rod 66, the two arc blocks 63 are reset and fit with the suspension rope 4. When another bevel gear 1 715 is combined with the transmission rod 2 712, the cam 86 starts to rotate.In this way, the piston outer rod 82 and the piston inner rod 83 begin to move as pistons, thereby extracting and exporting the lubricating oil in the oil storage tank 81. Combined with the oil guide pipe 88, the two arc blocks 63 can be effectively oiled when they fit the lifting rope 4, thereby reducing the friction between the lifting rope 4 and the pulley on the support frame 2 when the lifting rope 4 is retracted, and removing dust and debris on the surface of the lifting rope 4, thereby effectively avoiding the possibility of rope jamming during the lifting process of the small crane. The fundamental reason for the rope jamming is that when the small crane is lifting heavy objects, and combined with the construction environment, dust will adhere to the surface of the lifting rope 4, thereby increasing the friction between the lifting rope 4 and the pulley, which may cause the surface of the lifting rope 4 to become rough, thereby increasing the friction between the pulley and the lifting rope 4, which may cause plastic deformation when the rope is bent or the rope 4 breaks, thereby effectively improving the stability of the building material lifting device during use.

[0036] The transmission assembly 7 includes a pulley 71 installed on the output shaft of the winch 3, a mounting seat 72 with a mountain-shaped vertical section fixedly connected to the support frame 2, a transmission rod 73 rotatably connected to the mounting seat 72, one end of the transmission rod 73 extends to the outside of the mounting seat 72 and is connected to a pulley 2 74, a transmission belt 75 is connected between the pulley 2 74 and the pulley 1 71, wherein the transmission rod 1 73 is installed on the inner walls on both sides of the mounting seat 72, and the hollow rod 2 76 is installed on the protrusion of the mounting seat 72, so that the hollow rod 2 76 is sleeved on the outside of the transmission rod 1 73, combined with the internal pawl of the pulley 3 77 and the ratchet on the transmission rod 1 73, thereby realizing the winch 3 driving different pulleys 3 77 to rotate in forward and reverse directions.

[0037] A hollow rod 2 76 rotatably connected to the mounting seat 72 is provided on the outer side of the transmission rod 1 73, and both ends of the hollow rod 2 76 are rotatably connected to pulleys 3 77. Pulleys 4 78 are rotatably connected to the two side walls of the top of the support frame 2, and a transmission belt 2 79 is connected between the pulleys 4 78 and the pulleys 3 77. The ratchet assemblies between the two pulleys 3 77 and the corresponding transmission rod 1 73 are coupled in opposite ways, so that the winch 3 can effectively drive different pulleys 3 77 to rotate when rotating forward and reverse, thereby realizing the transmission of the pulleys 4 78 on both sides under different conditions.

[0038] The opposite side of the pulley four 78 is fixedly connected with a pulley five 710, and two side plates 711 with an L-shaped vertical cross-section are fixedly installed on the support frame 2. The side plates 711 are rotatably connected to the transmission rod two 712, and the transmission rod two 712 is fixedly installed with a pulley six 713. The pulley six 713 is connected to the pulley five 710 with a transmission belt three 714. Through the side plates 711, the transmission rod two 712 can be effectively rotated through the pulley six 713, combined with the bevel gear one 715, thereby effectively driving the spur gear one 718 to rotate synchronously.

[0039] The opposite ends of the transmission rod 2 712 are fixedly connected with bevel gear 1 715, and the outer sides of the bevel gear 1 715 are meshed with bevel gear 2 716. The mounting shaft holes of the bevel gear 2 716 are fixedly installed with transmission rod 3 717, and the transmission rod 3 717 is rotatably connected to the side plate 711. The tops of the bevel gear 2 716 are provided with spur gear 1 718 installed on the transmission rod 3 717, and the outer sides of the spur gear 1 718 are meshed with toothed rods. 719, the bottom end of the toothed rod 719 is fixedly installed with a guide seat 720, and the guide seat 720 is slidably connected to the side plate 711. The outer side of the toothed rod 719 is meshed with a spur gear 2 721, and a transmission rod 4 722 is fixedly installed in the mounting shaft hole of the spur gear 2 721. The transmission rod 4 722 is rotatably connected to the side plate 711, and a diamond block 723 installed on the transmission rod 4 722 is arranged between the spur gear 2 721 and the side plate 711. , wherein two spur gears 718 are staggeredly installed on the corresponding side plates 711, wherein one spur gear 718 is installed at the starting point of the toothed rod 719, and the other spur gear 718 is installed at the starting end of the toothed rod 719 after it is displaced. When the winch 3 rotates forward, the toothed rod 719, combined with the spur gear 2 721, can drive the diamond block 723 to rotate. At this time, the two arc blocks 63 are in an open state, making it more convenient to release the rope 4. A ratchet method is also adopted between the two spur gears 718 and the corresponding transmission rod 3 717, so that one of the spur gears 718 drives the toothed rod 719 to shift, and combined with the spur gears 2 721 on both sides, the other toothed rod 719 is also shifted synchronously, so that the other spur gear 718 is in an idling form. Therefore, when the arc block 63 is in an open state, the normal operation of the oil injection assembly 8 will not be triggered by mistake.

[0040] The lubrication assembly 6 includes two symmetrical arc frames 61 fixedly mounted on the side plate 711, each arc frame 61 is slidably connected with a hollow rod 62, and the opposite ends of the hollow rod 62 are connected with an arc block 63 for oiling the lifting rope 4, and telescopic rods 66 installed on the arc frame 61 are provided on both sides of the hollow rod 62, and two fixed blocks 67 of the same size are fixedly mounted on the telescopic rod 66, and a spring 68 installed on the telescopic rod 66 is provided between the fixed blocks 67, wherein the inside of the arc block 63 can be bonded with an elastic adsorption block, and a plurality of through holes are provided inside, so that the lubricating oil in the oil storage tank 81 can effectively and evenly penetrate into the arc block 63 through the oil guide pipe 88, and combined with the reversal of the winch 3, when the lifting rope 4 is wound up, the arc block 63 is squeezed by the spring 68, thereby starting to oil the lifting rope 4.

[0041] The bottom end of the hollow rod 62 is fixedly installed with a connecting seat 64, and both ends of the connecting seat 64 are fixedly connected with side blocks 65. The connecting seats 64 are slidably connected to the side plates 711. The side plates 711 are provided with through grooves that match the side blocks 65. The two side blocks 65 on the same side are both fitted with the diamond blocks 723. Through the side blocks 65 on both sides and the rotation of the diamond blocks 723, the distance between the side blocks 65 can be effectively changed, thereby realizing the separation or resetting of the two arc blocks 63.

[0043] A connecting block 84 is fixedly installed on the top of the piston inner rod 83, and a spring 85 installed on the piston inner rod 83 is arranged between the connecting block 84 and the piston outer rod 82. A cam 86 installed on the transmission rod 712 is arranged on the top of the connecting block 84. The two arc blocks 63 are reset by reversing the winch 3, and combined with the cam 86 and the spring 85, the piston inner rod 83 is driven to move and reset back and forth. In this way, the device can effectively perform oil injection when lifting materials, and the winch 3 rotates slowly when rising, thereby avoiding the phenomenon of dripping due to excessive oil absorption.

[0044] An oil storage tank 89 is fixedly installed at the bottom of the other side plate 711, and an oil suction pipe 810 is fixedly connected to the oil inlet of the oil storage tank 89. An oil collecting sleeve 811 is fixedly installed between the side plates 711. The oil inlet of the oil suction pipe 810 fits the inner bottom wall of the groove of the oil collecting sleeve 811. The oil collecting sleeve 811 adopts a frustum type, and an inclined baffle is adopted at the edge, so that the residual oil dripping from the hanging rope 4 can be collected. In combination with the oil suction pipe 810, cotton cloth is placed inside the oil suction pipe 810, so that the collected oil can be collected by capillary phenomenon. The lubricating oil inside the oil sleeve 811 is recovered, and the introduction of bottom dust can be effectively avoided, so that the lubricating oil quality of the oil storage tank 89 is better and convenient for secondary use. The oil storage tank 89 and the oil storage tank 81 are both provided with raw water inlet and raw water outlet, which is convenient for later cleaning and maintenance, and the internal crude oil can be replaced through the inlet and outlet. The oil collecting sleeve 811 is detachable and needs to be replaced due to long-term force friction, thereby ensuring that the oil collecting sleeve 811 fits the lifting rope 4 better, which makes the oil collecting effect better.

[0045] Embodiment 2:

[0046] like Fig. 9As shown, in the second embodiment, other structures remain unchanged. The present invention provides another structural form in which the piston outer rod 82 and the piston inner rod 83 extract the lubricating oil inside the oil storage tank 81. The structure includes the piston outer rod 82, the piston inner rod 83, the oil inlet pipe 87, the oil guide pipe 88, the sealing plug 10, the one-way valve 11, and the one-way valve 2 12. The structure includes a sealing plug 10 fixedly connected to the bottom end of the piston inner rod 83, the one-way valve 11 is rotatably connected to the sealing plug 10, and the one-way valve 2 12 is rotatably connected to the inner bottom wall of the piston outer rod 82, wherein the one-way valve 2 12 is provided at the oil inlet between the oil inlet pipe 87 and the piston outer rod 82, so that when the winch 3 is collecting the rope, it drives another pulley 3 77 to rotate, thereby causing another pulley 4 78 to drive pulley 5 710 to rotate, so that another pulley 6 713 drives transmission rod 2 712 to rotate, so that the cam 86 rotates and shifts, so that the piston inner rod 83 is driven by spring 2 85 When the piston inner rod 83 is reset, the piston inner rod 83 drives the sealing plug 10 to shift. Combined with the piston outer rod 82, the lubricating oil in the oil storage tank 81 can be effectively discharged from the box through the suction force formed by the piston inner rod 83. Combined with the one-way valve 12, the one-way valve 12 is in a sucked state at this time, thereby opening the oil guide, and the oil on the upper part of the sealing plug 10 can be effectively lifted and introduced into the arc block 63 through the oil guide pipe 88 to oil the surface of the lifting rope 4. When the cam 86 rotates and resets, it will squeeze the piston inner rod 83 downward, so that the sealing plug 10 shifts. Combined with the one-way valve 11 and the one-way valve 12, the one-way valve 12 is closed, and the one-way valve 11 is in an oil pressure open state, so that the oil area on the upper part of the sealing plug 10 is replenished with oil. This reciprocating motion realizes intermittent oil replenishment of the arc block 63, thereby effectively avoiding the phenomenon that excessive oil replenishment causes excessive oil stains on the lifting rope 4 to drip onto the hoisted material, thereby affecting the use of the material. In the second embodiment, in order to inject a more appropriate amount of oil into the building construction material lifting device when lifting the material, the above-mentioned piston outer rod 82 and piston inner rod 83 are combined with the sealing plug 10, the one-way valve 11 and the one-way valve 2 12 when pumping oil, so as to achieve intermittent oil replenishment of the arc block 63, which effectively saves the use of lubricating oil and avoids the phenomenon that excessive oil affects the lifted material.

The present invention provides another structural form for preventing the suspension rope 4 from being deviated to the left and right, which includes an anti-deflection component 9, a fixed plate 91, a guide rope wheel 92, a bent rod 1 93, a bent rod 2 94, a fixed block 2 95, a spring 3 96, a rotating rod 97, a spur gear 3 98, and a cross plate 99. The structure includes a fixed plate 91 fixedly mounted on the support frame 2, and two guide rope wheels 92 of the same size are arranged on the outer side of the fixed plate 91. The guide rope wheels 92 are fixedly mounted with bent rods 1 93 on both sides. The outer side of the rod 1 93 is slidably connected with a bent rod 2 94, and the other end of the bent rod 2 94 is fixedly installed on the fixed plate 91. The bent rod 2 94 and the bent rod 1 93 are fixedly connected with a fixed block 2 95. A spring 3 96 installed on the bent rod 2 94 and the bent rod 1 93 is arranged between the fixed block 2 95. The guide rope wheel 92 is fixedly connected with a rotating rod 97, and the rotating rod 97 is fixedly installed with a spur gear 3 98. The spur gears 3 98 are meshed with each other. A horizontal plate 99 is fixedly installed on the fixed plate 91, and the rotating rod 97 is rotatably connected to the horizontal plate 99. When the suspension rope 4 is deflected to the left or right, one of the guide rope wheels 92 will be deflected. When one of the guide rope wheels 92 is deflected, the guide rope wheel 92 will pull the curved rod 1 93 on one side to extend, while the curved rod 1 93 on the other side will be pressed into the curved rod 2 94. The curved rod 1 93 and the curved rod 2 94 are piston-type, and the curved rod 2 94 are connected in an upper and lower staggered manner. Combined with the spur gear 3 98, when the lower guide rope wheel 92 is deflected to one side, the upper guide rope wheel 92 is deflected to the other side. In the third embodiment, in order to make the lifting device for building materials more stable when lifting materials, the above two sets of guide rope wheels 92 are combined with the curved rod 2 94 and the curved rod 1 93 to form a relative force, thereby reducing the excessive deviation of the lifting rope 4 from the left to the right. In this way, the lifting device for building materials can effectively prevent the lifting rope 4 from being too large to the left and right, and effectively play a good role in resetting the lifting rope 4, thereby reducing the phenomenon that the material falls and causes injuries to personnel when the lifting device for building materials is lifted.
