Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope detection, in particular to a device for detecting the oil content of a steel wire rope of a tower crane. Background Art

[0002] The purpose of testing the oil content of crane wire ropes is to ensure that the wire ropes have sufficient strength and durability during use to ensure work safety. Through testing, we can accurately understand the oil content of the wire ropes, so as to take corresponding measures to optimize their performance and use effects.

[0003] At present, when testing the wire rope, it is usually necessary to first cut a section of the wire rope of appropriate length and fix it in the testing device, then loosen the wire rope, and pour a specific weight of solvent into the testing device to soak the wire rope, so as to leach out the oil on the wire rope, and finally drain the solvent and weigh it to detect the oil content in the wire rope. Although this method can detect the oil content of the wire rope, the wire rope needs to be soaked in the solvent for a long time before the oil is leached out, and after the solvent is drained, the solvent on the wire rope needs to be drained, and the draining time is long, which affects the detection efficiency of the oil content of the tower crane wire rope.

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The following describes a device for detecting oil content in a steel wire rope of a tower crane according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the tower crane wire rope oil content detection device of the embodiment of the utility model may include an outer box body 1, a detection mechanism 2, a joint control mechanism 3 and a weighing component 4.

[0025] The detection mechanism 2 may include a detection housing 20 , a motor 21 , an electric push rod 22 , two fixing clamping parts 23 and a pressing and rotating part 24 .

[0026] It should be noted that the outer box body 1 described in this embodiment is provided with an outer box door 10 to protect components such as the motor 21 .

[0027] The detection housing 20 is arranged on the outer box body 1 .

[0028] It should be noted that the detection shell 20 described in this embodiment is provided with a detection box door 200, so as to facilitate the fixing and disassembly of the wire rope. The detection box door 200 is a sealed box door, so as to prevent the leakage of the solvent. A solvent inlet 201 is provided at the top of the detection shell 20, and a solvent outlet 202 is provided at the bottom of the detection shell 20, so as to facilitate the entry and discharge of the solvent.

[0029] The motor 21 is arranged on the outer box body 1 and on one side of the detection housing 20 . One end of the electric push rod 22 is arranged on the motor 21 , and the other end of the electric push rod 22 extends into the detection housing 20 and is slidably and sealedly connected to the detection housing 20 .

[0030] It should be noted that the electric push rod 22 described in this embodiment is a component that can only be driven linearly by the extension shaft, and the extension shaft and the electric push rod 22 do not rotate, thereby ensuring that the motor 21 drives the electric push rod 22 and the fixed clamp 23 to loosen the wire rope.

[0031] The two fixing clamping members 23 are respectively arranged in the detection housing 20 , and are respectively arranged on the electric push rod 22 and the pressing and rotating member 24 .

[0032] It should be noted that the fixing clamp 23 described in this embodiment is a common clamping tool on the market, which fixes and clamps the wire rope, thereby ensuring the loosening of the wire rope and the rotation of the wire rope to soak in oil and spin away liquid.

[0033] The pressing and rotating member 24 is disposed at the other side of the detection housing 20 . One end of the pressing and rotating member 24 extends into the detection housing 20 and is slidably and sealingly connected to the detection housing 20 .

[0034] It can be understood that by setting the pressing rotating part 24, after the wire rope is loosened, the pressing rotating part 24 is controlled to elastically deform under the linear push of the electric push rod 22, so that under the rotational condition of the motor 21 doing work, the pressing rotating part 24 follows the rotation, thereby realizing the rotational oil immersion and rotational liquid throwing of the wire rope, thereby improving the detection efficiency of the device.

[0035] One end of the joint control mechanism 3 is connected to the motor 21 , and the other end of the joint control mechanism 3 is connected to the pressing rotating member 24 . The weighing assembly 4 is arranged at the bottom of the detection housing 20 .

[0036] It can be understood that, through the setting of the joint control mechanism 3, the motor 21 rotates to drive the pressing rotating member 24 to rotate, thereby loosening the fixed and clamped wire rope.

[0037] Specifically, during the actual operation, the relevant personnel open the detection box door 200, fix the cut steel wire rope on the two fixed clamps 23, and close the sealed box door, first weigh the solvent, and then pour part of the solvent into the detection shell 20 so that the solvent can completely soak the steel wire rope, weigh the weight of the unused solvent, and calculate the weight of the solvent in the detection shell 20.

[0038] Start the motor 21, which drives the electric push rod 22 and a fixed clamping member 23 to rotate clockwise. At the same time, the motor 21 drives the joint control mechanism 3 to rotate, and controls the pressing rotating member 24 and the other fixed clamping member 23 to rotate counterclockwise, thereby loosening the steel wire ropes on the two fixed clamping members 23, thereby facilitating the oil immersion of the steel wire ropes.

[0039] The extension shaft of the electric push rod 22 extends, thereby pushing a fixed clamping member 23, which pushes the wire rope and another fixed clamping frame, and pushes the pressing rotating member 24 to elastically deform, so that the pressing rotating member 24 rotates clockwise synchronously with the wire rope, thereby making the wire rope rotate when immersed in oil, shortening the oil immersion time of the wire rope.

[0040] The solvent after oil immersion flows into the weighing component 4 through the solvent outlet 202, and the motor 21 continuously drives the wire rope to rotate, so that the solvent on the wire rope is thrown out and slides into the weighing component 4, thereby shortening the solvent drainage time of the wire rope. After the solvent in the detection shell 20 is completely out of the weighing component 4, the solvent is weighed and calculated with the initial weight, thereby completing the oil content detection of the device.

[0041] In one embodiment of the present invention, Figure 2-Figure 5 As shown, the pressing and rotating member 24 may include a clamping tube 241 , an elastic telescopic rod 242 and an elastic clamping member 243 .

[0042] Among them, one end of the clamping tube 241 is arranged on the joint control mechanism 3, and a plurality of clamping grooves 2410 are arranged on the clamping tube 241. One end of the elastic telescopic rod 242 is connected to the fixed clamping member 23, and the other end of the elastic telescopic rod 242 is connected to the clamping tube 241. One end of the elastic clamping member 243 is arranged on the outer tube of the elastic telescopic rod 242, and the other end of the elastic clamping member 243 is arranged in the clamping groove 2410, and slides against the clamping tube 241.

[0043] It should be noted that the elastic telescopic rod 242 described in this embodiment includes an outer tube and a telescopic rod, and one end of the telescopic rod is arranged in the outer tube and is slidably connected to the outer tube. A spring 2432 is arranged in the outer tube, and the outer tube is arranged on a side close to the fixed clamping member 23, thereby ensuring the clamping and sliding release of the elastic clamping member 243 and the clamping tube 241.

[0044] In one embodiment of the present invention, Figure 2-Figure 5 As shown, the elastic clamping member 243 may include a telescopic block 2430 , a fixing cylinder 2431 and a spring 2432 .

[0045] Among them, the telescopic block 2430 is arranged in the slot 2410, and a ball is arranged on the telescopic block 2430, one end of the telescopic block 2430 is abutted against the clamping tube 241, and the other end of the telescopic block 2430 extends into the fixed tube 2431, and the fixed tube 2431 is arranged on the outer tube of the elastic telescopic rod 242, and the spring 2432 is arranged in the fixed tube 2431, one end of the spring 2432 is connected to the fixed tube 2431, and the other end of the spring 2432 is connected to the telescopic block 2430.

[0046] It can be understood that the friction between the telescopic block 2430 and the clamping tube 241 is reduced by providing the ball.

[0047] In one embodiment of the present invention, Figure 2-Figure 5 As shown, the joint control mechanism 3 may include a first gear 30 , a second gear 31 , a linkage rod 32 , a third gear 33 , a direction adjustment gear 34 and a control gear 35 .

[0048] Among them, the first gear 30 is set on the output shaft of the motor 21, the second gear 31 is meshed with the first gear 30, the second gear 31 and the third gear 33 are respectively set at both ends of the linkage rod 32, the linkage rod 32 is rotatably set on the outer box body 1, the adjustment gear 34 is rotatably set on the outer box body 1 and meshed with the third gear 33, the control gear 35 is rotatably set on the outer box body 1 and meshed with the adjustment gear 34, and the clamping cylinder 241 is set on the control gear 35.

[0049] It can be understood that, by setting the direction-adjusting gear 34, the rotation direction of the output shaft of the motor 21 is changed to ensure the loosening effect of the fixed clamping member 23 on the wire rope.

[0050] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the weighing assembly 4 may include a solvent container 40 and a weigher 41 .

[0051] The solvent container 40 is disposed at the bottom of the solvent outlet 202 opened in the detection housing 20 , and the weigher 41 is disposed at the bottom of the solvent container 40 .

[0052] It should be noted that the accuracy of the weighing device 41 described in this embodiment is 0.001 grams, thereby ensuring the detection effect of the device.

[0053] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a hot air blower 5 may also be included. The hot air blower 5 is provided with an air duct 50 , and one end of the air duct 50 extends into the detection housing 20 .

[0054] It can be understood that, by providing the hot air blower 5, the draining time of the wire rope solvent is further shortened, thereby improving the detection efficiency of the device.

[0055] Specifically, during the actual operation, the relevant personnel open the detection box door 200, fix the cut steel wire rope on the two fixed clamps 23, and close the sealed box door, first weigh the solvent, and then pour part of the solvent into the detection shell 20 so that the solvent can completely soak the steel wire rope, weigh the weight of the unused solvent, and calculate the weight of the solvent in the detection shell 20.

[0056] Start the motor 21, which drives the electric push rod 22 and a fixed clamping member 23 to rotate clockwise. At the same time, the motor 21 drives the first gear 30 to rotate, and drives the second gear 31, the third gear 33 and the adjustment gear 34 to rotate, so that the control gear 35, the pressing rotating member 24 and the other fixed clamping member 23 rotate counterclockwise, thereby loosening the wire ropes on the two fixed clamping members 23, thereby facilitating the oil immersion of the wire ropes.

[0057] The extension shaft of the electric push rod 22 extends, thereby pushing a fixed clamping member 23, which pushes the wire rope and another fixed clamping frame, and pushes the elastic telescopic rod 242 to contract, so that the telescopic block 2430 slides and abuts against the clamping tube 241, and slides to the inside of the clamping tube 241, so that the telescopic block 2430 rotates synchronously with the wire rope clockwise, and is rotatably connected with the clamping tube 241, so that the wire rope rotates when immersed in oil, shortening the oil immersion time of the wire rope.

[0058] The solvent after oil immersion flows into the weighing component 4 through the solvent outlet 202, and the motor 21 continuously drives the steel wire rope to rotate, so that the solvent on the steel wire rope is thrown out and slides into the weighing component 4. Under the blowing of the hot air blower 5, the solvent draining time of the steel wire rope is greatly shortened. After the solvent in the detection shell 20 is completely out of the weighing component 4, the solvent is weighed and calculated with the initial weight, thereby completing the oil content detection of the device.

[0059] In summary, the tower crane wire rope oil content detection device of the utility model embodiment, by loosening the wire rope and driving the wire rope to rotate, can not only make the wire rope fully contact with the solvent, shorten the immersion time of the wire rope in the solvent, and accelerate the leaching efficiency of the oil, but also help to throw out the solvent attached to the wire rope, accelerate the drainage efficiency of the wire rope, and thus improve the detection efficiency of the oil content of the tower crane wire rope.
