Description

Technical Field

[0001] The invention relates to the technical field of broken traction ropes of load trolleys, and particularly proposes a broken traction rope protection device for a load trolley of a tower crane. Background Art

[0002] Tower crane is also called tower crane. It is a rotating crane with a boom mounted on the upper part of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It is usually used in conjunction with a load trolley. During the luffing movement of the tower crane's load trolley, in order to improve the protection performance of the traction rope, the traction rope needs to be maintained and serviced frequently. This can effectively prevent the traction rope from getting knotted, bent, and stuck with debris during use. The existing method of maintaining the traction rope is to directly apply grease to the traction rope.

[0003] However, the following problems still exist in the process of maintaining the traction rope: 1. In the process of applying grease to the traction rope, since the traction rope is generally a twisted wire, and the twisted wire is generally made of multiple strands, there are easily gaps between them. Therefore, when applying the grease, uneven application is likely to occur, which has a certain impact on the service life of the traction rope and reduces the protective effect.

[0004] 2. Before applying grease to the traction rope, it is generally not cleaned in the traditional way. During the lifting process, it is inevitable that debris will remain on the traction rope. The traction rope increases friction during the traction work, which reduces the service life of the traction rope and is prone to rope breakage, thereby reducing the protection effect of the traction rope.

[0005] Therefore, in order to improve the protection effect of the traction rope and reduce the friction during use, the present invention provides a tower crane load trolley traction rope breakage protection device. Summary of the Invention

Embodiment

[0033] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings. In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Refer to Figure 1 and Figure 2 A rope breaking protection device for the traction rope of a tower crane load trolley includes a smearing mechanism 1 connected to the truck A for smearing grease, and a cleaning mechanism 2 connected to the truck A for cleaning the rope B is disposed below the smearing mechanism 1.

[0035] Refer to Figure 1 、 Figure 3 and Figure 6The smearing mechanism 1 includes a U-shaped frame 11 with an opening upward connected to the truck A, and a rotating rod 12 for winding the rope B is rotatably provided on the front and rear inner walls of the U-shaped frame 11 near the left side. The rear end face of the U-shaped frame 11 is fixedly installed with a first forward and reverse motor connected to the rotating rod 12 through a motor seat, and two horizontally placed guide rods 13 are rotatably provided on the front and rear inner walls of the U-shaped frame 11 above the rotating rod 12 near the right side. Two groups of limiting assemblies 14 arranged from left to right are provided on the front and rear inner walls of the U-shaped frame 11 between the two guide rods 13, and a scraping assembly 15 is provided on the limiting assembly 14. A moving assembly 16 is also provided on the front and rear side walls of the U-shaped frame 11, and a removable cover is provided on the top of the U-shaped frame 11.

[0036] See Figure 3 A horizontal plate 111 is fixedly installed at the bottom of the inner wall of the U-shaped frame 11 through a cylinder. A fixed frame 112 for holding grease is provided on the left side of the horizontal plate 111. A guide groove is provided near the top of the right end surface of the fixed frame 112. A receiving frame 113 connected to the fixed frame 112 is provided on the right side of the horizontal plate 111. A guide plate 114 corresponding to the guide groove is fixedly installed on the inner wall of the receiving frame 113 near the top, which is inclined downward from right to left.

[0037] In the original state, first remove the cover plate on the top of the U-shaped frame 11, then place the rope B for hoisting between the rotating rod 12 and the guide rod 13, and finally place the grease for smearing and curing in the fixed frame 112 on the horizontal plate 111, and add the grease to a suitable height so that the wound-up hoisting rope B is located in the grease. Before the rope B is used for hoisting, the rope B is evenly smeared and cured in the grease to avoid knotting during use, thereby further improving the protection effect of the rope B. The immersion-type smearing and curing method prevents the traditional uneven smearing from affecting the service life of the rope B. Before using the rope B for hoisting, first install the scraper assembly 15 on the limit assembly 14, and install it. Afterwards, the provided moving component 16 is used to make the scraping component 15 contact the rope B. During the lifting process of the rope B, the scraping component 15 is used to scrape off the excess residual grease on the rope B through the moving component 16 to avoid dripping and affecting the lifting. The scraped excess grease passes through the guide plate 114 on the receiving frame 113 and then through the guide groove and finally enters the fixed frame 112 to avoid waste. During the winding process, the provided cylinder can ensure that the rope B is always located in the grease in the fixed frame 112. The cover plate provided on the top of the U-shaped frame 11 can cover the grease in the fixed frame 112 to prevent other impurities from falling into the grease and affecting the maintenance of the rope B.

[0038] See Figure 5 and Figure 6 The limit assembly 14 includes a movable plate 141 slidably connected between the front and rear side walls of the U-shaped frame 11, and semi-arc blocks 142 are fixedly installed on the opposite surfaces of the front and rear movable plates 141. The upper and lower side walls of the semi-arc block 142 on the front side are symmetrically provided with fixing grooves, and the upper and lower side walls of the semi-arc block 142 on the rear side are fixedly installed with fixing blocks 143 that cooperate with the fixing grooves. The fixing block 143 has a trapezoidal structure near one end of the fixing groove, which plays a guiding role and is convenient for entering the fixing groove. The inner diameter of the semi-arc block 142 gradually increases from left to right, and a limiting groove that passes through the movable plate 141 is provided in the middle of the semi-arc block 142. A limiting block 144 with a T-shaped structure is slidably provided on the top of the movable plate 141. The horizontal section of the limiting block 144 is fixedly connected to the movable plate 141 by an extrusion spring 145.

[0039] Continue reading Figure 5 and Figure 6 The scraping assembly 15 includes a protruding plate 151 that cooperates with the upper limit groove of the semi-arc block 142. The opposite surfaces of the front and rear protruding plates 151 are fixedly installed with arc plates 152 that cooperate with the semi-arc block 142. The inner side walls of the arc plates 152 are fixedly installed with scraping brushes 153 for scraping excess grease from the rope B, and the density of the scraping brushes 153 on the left and right limit assemblies 14 is different.

[0040] Continue reading Figure 5 and Figure 6 The moving assembly 16 includes a wedge block 161 fixedly connected between the two moving plates 141 on the same side of the limit assembly 14. The wedge block 161 is connected to the side wall of the U-shaped frame 11 through multiple return springs 162. The side wall of the U-shaped frame 11 is symmetrically provided with displacement grooves in the front and back. A support plate 163 with an L-shaped structure is slidably connected in the displacement groove through an electric slider. A wedge block 164 with a second structure that cooperates with the wedge block 161 is fixedly installed on the top of the support plate 163.

[0041] The limit assembly 14 is provided so that the scraping assembly 15 can be replaced and fixed in time. The specific replacement method is: pull the limit block 144 to move upward so that the vertical section of the limit block 144 is out of the limit groove. At this time, the extended plate 151 is placed in the limit groove. After placement, release the limit block 144. Next, under the reaction force of the extrusion spring 145, the limit block 144 limits and fixes the extended plate 151, and the scraping brush 153 can be replaced at any time. After the scraping brush 153 is installed, the electric slider is started to drive the support plate 163 to move downward in the displacement groove. The support plate 163 makes the second wedge block 164 cooperate with the first wedge block 161, and makes one The movable plate 141 on the wedge block 161 drives the front and rear semi-arc blocks 142 to move toward each other, so that the fixed block 143 is clamped into the fixed groove and the scraping brush 153 contacts the rope B. During the lifting of the rope B, the scraping brush 153 scrapes off the excess residual grease on the rope B to avoid dripping and affecting the lifting. The scraped grease drips downward through the arc plates 152 with different inner diameters, passes through the guide plate 114 and the guide groove, and finally enters the fixed frame 112 to avoid waste. The different densities of the scraping brushes 153 on the left and right limit assemblies 14 can better scrape off the grease on the rope B.

[0042] See Figure 1 、 Figure 3 and Figure 7 The cleaning mechanism 2 includes a fixed plate 21 connected to the truck A, and a rectangular through groove is opened in the middle of the fixed plate 21. A stabilizing plate 22 is symmetrically arranged in the rectangular through groove for sliding front and back. The two stabilizing plates 22 are connected by a threaded adjustment rod 23 with opposite rotation directions. The rear end surface of the fixed plate 21 is fixedly installed with a second forward and reverse motor connected to the threaded adjustment rod 23 through a motor seat. The opposite surfaces of the two stabilizing plates 22 are symmetrically provided with a cleaning assembly 25 of a cleaning rope B through an upper and lower staggered support assembly 24, and a fixing assembly 26 that can be quickly disassembled for cleaning the cleaning assembly 25 is also provided on the support assembly 24.

[0043] When hoisting and winding rope B, the second forward and reverse motor is started first. The second forward and reverse motor causes the two stabilizing plates 22 on the threaded adjusting rod 23 to move toward each other. The supporting assembly 24 on the stabilizing plate 22 causes the cleaning assembly 25 to contact the rope B. During the winding of rope B, the cleaning assembly 25 can be used to clean debris on the rope B, so as to reduce friction loss and clean and protect the rope. At the same time, the detachable fixing assembly 26 can be used to clean the debris on the cleaning assembly 25 after cleaning, which will not affect the cleaning of rope B.

[0044] See Figure 3 and Figure 4 The support component 24 includes a rectangular block 241 fixedly connected to the stabilizing plate 22. At one end of the rectangular block 241 away from the stabilizing plate 22, there is fixedly installed an L-shaped structural plate 242 connected to the vertical section. On the top of the horizontal section of the L-shaped structural plate 242, there is fixedly installed a material storage box 243 for containing cleaning debris. On the top of the vertical section of the L-shaped structural plate 242, there is a rectangular groove, and in the rectangular groove, there is a reverse L-shaped plate 244 for installing the cleaning component 25 slidably arranged through a telescopic spring.

[0045] Refer to Figure 5 、 Figure 7 and Figure 8 The cleaning component 25 includes three rotating rollers 251 in a triangular structure rotatably arranged with the reverse L-shaped plate 244. On the top of the reverse L-shaped plate 244, there is a driving motor fixedly connected to one of the rotating rollers 251. The three rotating rollers 251 are传动连接(此处原文可能有误,推测是“driven connected”) by a cleaning belt 252. On the outer sidewall of the cleaning belt 252, there are replaceable cleaning bristles 253. At the upper and lower ends of the cleaning belt 252, there are semi-circular plates 254 for limiting the cleaning belt 252. Between the two semi-circular plates 254, there is a fixing connection through a C-shaped plate 255. The top of the C-shaped plate 255 is fixedly connected to the horizontal section of the reverse L-shaped plate 244 through an extending block.

[0046] When the second forward and reverse motor is started to make the two stabilizing plates 22 move towards each other, the reverse L-shaped plate 244 makes the cleaning bristles 253 on the cleaning belt 252 contact the rope B. When the rope B is being hoisted and wound up, the driving motor is started, and the driving motor makes the rotating roller 251 drive the cleaning belt 252 to rotate. At this time, the cleaning bristles 253 on the cleaning belt 252 can clean the debris on the rope B in all aspects, avoiding the residue of debris on the rope B to increase friction and thus reduce the protection effect of the rope B. During the cleaning process, through the set fixing component 26, the debris cleaned on the cleaning bristles 253 can be scraped off and the scraped debris can fall into the material storage box 243.

[0047] Refer to Figure 5 and Figure 7 The fixing component 26 includes a support block 261 fixedly connected to the bottom of the material storage box 243 and parallel to the straight end of the cleaning belt 252. On the top of the support block 261, there is a T-shaped groove, and in the T-shaped groove, there is a detachable T-shaped plate 262 slidably arranged. At one end of the T-shaped plate 262 close to the cleaning belt 252, there is a cleaning comb 263 for cleaning the cleaning bristles 253.

[0048] By setting the support block 261 and the T-shaped plate 262 as a detachable structure, the cleaning comb 263 can be removed for cleaning or replaced at any time. The specific replacement method is: pull the inverted L-shaped plate 244 to slide in the rectangular groove on the L-shaped structural plate 242, and finally slide the T-shaped plate 262 into the T-shaped groove on the support block 261.

[0049] In the first step, in the original state, first remove the cover plate on the top of the U-shaped frame 11, then place the rope B used for lifting between the rotating rod 12 and the guide rod 13, and finally place the grease used for maintenance into the fixed frame 112 on the horizontal plate 111, and add the grease to a suitable height so that the wound-up lifting rope B is located in the grease. Before using the rope B for lifting, first install the scraping assembly 15 on the limit assembly 14. After installation, use the provided moving assembly 16 to make the scraping assembly 15 contact the rope B.

[0050] In the second step, during the hoisting process of rope B, the scraping brush 153 scrapes off the excess grease remaining on the rope B to avoid dripping and thus affecting the hoisting. The scraped grease drips downward through the arc plates 152 with different inner diameters, passes through the guide plates 114 and the guide grooves, and finally enters the fixed frame 112 to avoid waste.

[0051] The third step is that when the rope B is being wound, the second forward and reverse motor is started first. The second forward and reverse motor causes the two stabilizing plates 22 on the threaded adjusting rod 23 to move toward each other. The supporting assembly 24 on the stabilizing plate 22 causes the cleaning assembly 25 to contact the rope B. At this time, the driving motor is started, and the driving motor causes the rotating roller 251 to drive the cleaning belt 252 to rotate. At this time, the cleaning bristles 253 on the cleaning belt 252 can clean all aspects of the debris on the rope B to prevent debris from remaining on the rope B, increasing friction and thus reducing the protection effect of the rope B. During the cleaning process, the fixed assembly 26 can scrape off the debris cleaned on the cleaning brush 253, and the scraped debris falls into the material box 243.
