Description

Technical Field

[0001] The present application relates to the technical field of wire rope protection, and in particular to a wire rope rain cover device. Background Art

[0002] The wire rope is an important part of the gantry crane. The lifting mechanism completes the lifting work through the transmission of the wire rope and the lifting pulley. In the general design of the gantry crane, the lifting mechanism is generally located in the machine room, which has the function of heat preservation and rain protection, but the wire rope needs to pass through the top of the machine room to connect with the lifting pulley. During the lifting process, the wire rope will inevitably interfere with the top of the machine room, so it is necessary to open a hole in the top of the machine room to ensure the passability of the wire rope. In order to ensure the rainproof performance of the machine room, it is necessary to add a wire rope rain cover device.

[0003] Existing wire rope rain cover devices often use fixed rain covers or unidirectional swinging rain covers. During the wire rope hoisting process, when the drum is winding the wire rope, the wire rope will swing left and right. When the number of winding layers increases, the front and back directions will also move. Therefore, fixed and unidirectional swinging rain covers cannot meet the use requirements, which may cause the wire rope to get stuck and wear, thus affecting the normal use of the crane.

[0004] In addition, the existing wire rope rain cover device is provided with an outlet sleeve at the top, and four rollers are installed at the outlet sleeve position to assist the movement of the wire rope and avoid wear between the wire rope and the outlet sleeve. However, the gap of the outlet sleeve is too large, and rainwater can easily enter the inside of the rain cover shell from the outlet sleeve position. The inside of the rain cover shell is connected to the inside of the machine room, and rainwater will enter the inside of the machine room. Moreover, the rainwater entering the machine room will soak the wire rope in the drum, emulsify the protective lubrication layer of the wire rope, and reduce the service life of the wire rope.

[0039] Refer to the following Figures 1 to 10 This embodiment describes a wire rope rain cover device, including a rain cover shell 100 and an outlet component 400.

[0040] like Figures 1 to 4 As shown, the rain cover housing 100 includes a fixed cover 111, a first movable cover 121 and a second movable cover 131. Fig. 9 The fixed cover 111 is fixedly arranged, specifically welded to the top of the machine room 511 , thereby ensuring the water tightness between the bottom of the rain cover shell 100 and the machine room 511 .

[0041] The lower part of the first movable cover 121 and the upper part of the fixed cover 111 are hinged with the first axis 201 through the first hinge part, the lower part of the second movable cover 131 and the upper part of the first movable cover 121 are hinged with the second axis 301 through the second hinge part, the first axis 201 and the second axis 301 are not arranged coplanarly, the fixed cover 111 has a first space for the steel wire rope 521 to pass through, the first movable cover 121 has a second space for the steel wire rope 521 to pass through, and the second movable cover 131 has a third space for the steel wire rope 521 to pass through, and the first space, the second space and the third space are connected to each other.

[0042] The outlet component 400 is used for the wire rope to pass through and is arranged on the top of the second movable cover 131. Fig.10After the wire rope 521 passes through the top of the machine room 511, it passes through the first space, the second space and the third space in sequence, and then passes through the exit component 400. In the prior art, a perforation is provided on the top of the machine room 511 for the wire rope to pass through, which will not be described in detail here.

[0043] It can be understood that the steel wire rope 521 wound by the drum swings left and right and front and back, and the outlet component 400 arranged on the top of the second movable cover 131 moves with the steel wire rope 521, and the second movable cover 131 can swing relative to the first movable cover 121 with the second axis 301, and the first movable cover 121 can swing relative to the fixed cover 111 with the first axis 201, and the first axis 201 and the second axis 301 are not arranged in the same plane, that is, the swing direction of the first movable cover 121 is different from the swing direction of the second movable cover 131, and finally the second movable cover 131 can swing with the outlet component 400, so that the inclination angle of the rain cover shell matches the steel wire rope to reduce the scratching of the steel wire rope and the rain cover shell. In this embodiment, the steel wire rope rain cover device can better adapt to the swinging of the steel wire rope in multiple directions, and can prevent rainwater from entering the fixed cover when following the swinging of the steel wire rope, and the waterproof performance of the rain cover shell is guaranteed, which can prevent the steel wire rope from swinging back and forth and left and right during the winding process of the drum and causing damage to the rain cover. The wire rope rain cover device of this embodiment can increase the service life of the wire rope, play a rainproof role in the machine room, protect the wire rope in the drum to prevent rainwater from soaking the wire rope in the drum, prevent emulsification of the wire rope, and thus protect the lubrication layer.

[0044] like Figure 1 As shown, the rain cover shell 100 is tilted as a whole by designing a bevel at the bottom of the fixed cover 111. After being welded to the machine room 511, the rain cover shell 100 is tilted as a whole.

[0045] Reference Figure 1 and Figure 2 In this embodiment, the fixed cover 111 and the first movable cover 121 are both in a square tube shape, and the lower portion of the first movable cover 121 is covered over the upper portion of the fixed cover 111, so that the upper portion of the fixed cover 111 is not exposed to the outside, thereby preventing rainwater from entering the interior of the fixed cover 111. It should be noted that the first movable cover 121 is equipped with an inspection cover, which is mounted on the first movable cover 121 using fasteners.

[0046] Among them, Figure 3 As shown, the first hinged portion includes two first hinged assemblies 200 respectively arranged on the left and right sides of the lower opening of the first movable cover 121, and the first axis 201 is arranged along the left and right directions. The left and right sides of the lower opening of the first movable cover 121 are respectively hinged to the left and right sides of the upper opening of the fixed cover 111 through the first hinged assemblies 200. Figure 2It is understood that the first movable cover 121 swings back and forth relative to the fixed cover 111 about the first axis 201. The maximum swing angle α of the first movable cover 121 can be adaptively adjusted according to the change amplitude of the wire rope by adjusting the size of the first movable cover 121 and the fixed cover 111 and the gap between them.

[0047] Figure 7 Only the cross-sectional structure of one of the first hinge components 200 is shown, and the other one can be arranged in a symmetrical structure. Figure 7 As shown, the first hinge assembly 200 includes a first pin shaft 211, a first sleeve 221, a first washer 231 and a first pin 232. The first sleeve 221 passes through the side wall of the first movable cover 121 and the side wall of the fixed cover 111. The fixed cover 111 has a first axial hole for the first sleeve 221 to pass through. The first movable cover 121 has a second axial hole for the first sleeve 221 to pass through. The first axial hole and the second axial hole are slightly larger than the outer diameter of the first sleeve 221, which can ensure that the first movable cover 121 and the fixed cover 111 can rotate relative to the sleeve 221. The first pin shaft 211 passes through the first sleeve 221, and the end of the first pin shaft 211 abuts against one end of the first sleeve 221. The first washer 231 passes through the first pin shaft 211 and abuts against the other end of the first sleeve 221. The first pin 232 is fixed to the end of the first pin shaft 211 to limit the first washer 231 from sliding out. Figure 7 As shown, the end of the first pin shaft 221 cooperates with the first washer 231 at the other end to limit the side wall of the first movable cover 121 and the side wall of the fixed cover 111 to ensure that the first shaft sleeve 221 does not slide out.

[0048] In addition, a first oil injection channel 212 is provided inside the first pin shaft 211. The first oil injection channel 212 extends axially from the end of the first pin shaft 211 and radially extends to the outer periphery at the middle of the first pin shaft 211. The injection port of the first oil injection channel 212 is provided at the end of the first pin shaft 211. The injection port of the first oil injection channel 212 is installed with a first oil seal 213. When lubricating, the first oil seal 213 can be removed, and then lubricating grease is injected from the injection port of the first oil injection channel 212. The lubricating grease flows to the inner periphery of the first shaft sleeve 221 through the first oil injection channel 212. The first shaft sleeve 221 is also provided with a plurality of radial connecting holes at the middle position. The lubricating grease can flow from the connecting holes to the outer periphery of the first shaft sleeve 221. In this way, the first movable cover 121 and the fixed cover 111 can maintain good rotation performance relative to the first shaft sleeve 221.

[0049] It should be noted that this embodiment shows the specific structure of the first hinge part, and in other embodiments, other structures can be used to realize the hinge between the first movable cover 121 and the fixed cover 111. For example, the first hinge assembly can use a first pin shaft plus a first pin, which can also realize the hinge function, but the rotation performance is not as smooth as that of this embodiment.

[0050] The fixed cover 111 is provided with a first pad 112 and a second pad 113 located on the inner and outer sides of the side wall at the position of the first axial hole, and the first movable cover 121 is provided with a third pad 122 and a fourth pad 123 located on the inner and outer sides of the side wall at the position of the second axial hole. In this way, the first movable cover 121 and the fixed cover 111 can rotate relative to the first shaft sleeve 221, thereby avoiding wear on the side walls of the first movable cover 121 and the fixed cover 111.

[0051] Reference Figure 3 and Figure 4 The upper part of the second movable cover 131 is in the shape of a cone, the lower part of the second movable cover 131 is in the shape of a square cylinder, and the lower part of the second movable cover 131 is covered on the upper opening of the first movable cover 121, so that the upper opening of the first movable cover 121 is not exposed to the outside, and rainwater is prevented from entering the interior of the first movable cover 121. Further supplementary explanation, the shape of the second movable cover 131 is difficult to manufacture as a whole, and those skilled in the art can manufacture it in half, and then use fasteners to connect,

[0052] Among them, Figure 1 As shown, the second hinged portion includes two second hinged assemblies 300 disposed at the front and rear sides of the lower opening of the second movable cover 131, and the second axis 301 is inclined along the front-to-back direction. Figure 2 It can be seen that since the first movable cover 121 and the fixed cover 111 will swing in the front-to-back direction, the second hinge part will change, and the second axis 301 will also change. The second axis 301 is perpendicular to the first axis 201, and the second axis 301 will rotate back and forth around the first axis 201, but the second axis 301 is always arranged in the front-to-back direction. As for whether the direction of the second axis 301 is horizontal or inclined front-to-back, it will change with the position of the first movable cover 121.

[0053] The front and rear sides of the lower opening of the second movable cover 131 are respectively hinged to the front and rear sides of the upper opening of the first movable cover 121 through the second hinge assembly 300. Figure 4 It is understood that the second movable cover 131 swings left and right relative to the first movable cover 121 about the second axis 301. The maximum swing angle β of the second movable cover 131 can be adaptively adjusted according to the change amplitude of the wire rope, by adjusting the size of the second movable cover 131 and the first movable cover 121 and the gap between them.

[0054] Figure 8 Only the cross-sectional structure of one of the second hinge components 300 is shown, and the other one can be arranged in a symmetrical structure. Figure 8 As shown, the second hinge assembly 300 includes a second pin shaft 311, a second sleeve 321, a second washer 331 and a second pin 332. The second sleeve 321 passes through the side wall of the second movable cover 131 and the side wall of the first movable cover 121. The first movable cover 121 has a third shaft hole for the second sleeve 321 to pass through. The second movable cover 131 has a fourth shaft hole for the second sleeve 321 to pass through. The second pin shaft 311 passes through the second sleeve 321, and the end of the second pin shaft 311 abuts against one end of the second sleeve 321. The second washer 331 passes through the second pin shaft 311 and abuts against the other end of the second sleeve 321. The second pin 332 is fixed to the end of the second pin shaft 311 to limit the second washer 331 from sliding out. Figure 8 As shown, the end of the second pin shaft 321 cooperates with the second washer 331 at the other end to limit the side wall of the second movable cover 131 and the side wall of the first movable cover 121 to ensure that the second shaft sleeve 321 does not slide out.

[0055] In addition, a second oil injection channel 312 is provided inside the second pin shaft 311. The second oil injection channel 312 extends axially from the end of the second pin shaft 311 and radially extends to the outer periphery at the middle of the second pin shaft 311. The injection port of the second oil injection channel 312 is provided at the end of the second pin shaft 311. The injection port of the second oil injection channel 312 is installed with a second oil seal 313. When lubricating, the second oil seal 313 can be removed, and then lubricating grease is injected from the injection port of the second oil injection channel 312. The lubricating grease flows to the inner periphery of the second shaft sleeve 321 through the second oil injection channel 312. The second shaft sleeve 321 is also provided with a plurality of radial connecting holes at the middle position. The lubricating grease can flow from the connecting holes to the outer periphery of the second shaft sleeve 321. In this way, the second movable cover 131 and the first movable cover 121 can maintain good rotation performance relative to the second shaft sleeve 321.

[0056] It should be noted that this embodiment shows the specific structure of the second hinge part, and in other embodiments, other structures can also be used to realize the hinge between the second movable cover 131 and the first movable cover 121. For example, the second hinge assembly can use a second pin shaft plus a second pin, which can also realize the hinge function, but the rotation performance is not as smooth as that of this embodiment.

[0057] The first movable cover 121 is provided with a fifth pad 124 and a sixth pad 125 located at both sides of the inner and outer sides of the side wall at the position of the third shaft hole, and the second movable cover 131 is provided with a seventh pad 134 and an eighth pad 135 located at both sides of the inner and outer sides of the side wall at the position of the fourth shaft hole. In this way, the first movable cover 121 and the second movable cover 131 can rotate relative to the second shaft sleeve 321, so that the side wall of the first movable cover 121 and the side wall of the second movable cover 131 can be prevented from being worn.

[0058] The existing wire rope rain cover device uses a rubber sheet as the shell, which has poor rainproof performance. After a period of use, the rubber sheet is prone to aging, affecting the rainproof performance. The rubber sheet is in direct contact with the wire rope, causing great wear on the wire rope, which affects the life of the wire rope. At the same time, the weight of the rain cover shell is too large, which puts too much pressure on the wire rope. When the wire rope is under less force, it may not be able to drive the rain cover to move synchronously, which also aggravates the wear of the wire rope.

[0059] In this embodiment, the rain cover shell is made of aluminum alloy, which is light in weight and easy to install, and the fixed cover 111 is welded to the top of the machine room 511. The rain cover shell is made of aluminum alloy, and because of its light weight, when the tension of the wire rope is small when it is unloaded, the first movable cover and the second movable cover can also swing with the wire rope, avoiding the situation where the first and second movable covers cannot be driven back to their original positions.

[0060] Specifically, combined Figure 5 and Figure 6 The outlet component 400 includes a support assembly fixed to the top of the second movable cover 131 and two rollers arranged on the support assembly. The middle of the roller 431 is concave to form an arc groove 432. The two rollers 431 are adjacent to each other and arranged side by side so that a rope passage 401 matching the size of the wire rope 521 is formed between the two arc grooves 432. The connecting support 410 is provided with a first rope hole 413 for the wire rope 521 to pass through.

[0061] It is understandable that, at present, the exit components all use four rollers to assist the movement of the wire rope, but the gap between the roller and the wire rope is very large. Even through adjustment, the gap is difficult to adjust to the ideal range. Rainwater can easily enter the rain cover shell from the gap position. The interior of the rain cover shell is connected to the interior of the machine room, and rainwater will enter the interior of the machine room. In this embodiment, the middle of the roller 431 is concave to form an arcuate groove 432. After the two rollers 431 are installed adjacent to each other, a rope threading channel 401 is formed between the two arcuate grooves 431. The wire rope 521 passes through the rope threading channel 401. In the process of winding the wire rope on the drum, the friction between the wire rope 521 and the roller 431 is in the form of rolling friction, which can greatly reduce the friction force and friction loss of the wire rope 521. In addition, the arcuate groove 432 is formed by the concave setting in the middle of the roller 431. Only two rollers 432 are needed to cooperate to form the rope threading channel 401. The rope threading channel 401 is slightly larger than the outer diameter of the wire rope. The gap between the wire rope 521 and the roller 431 is small, which can better play a role in waterproofing and rainproofing. Those skilled in the art can refer to the specific application. Figure 5 The size of the rope threading channel can be designed to be the outer diameter of the wire rope plus the thickness of the lubricating grease applied, so that it is difficult for rainwater to enter the rain cover shell through the gap.

[0062] Specifically, if Figure 5 As shown, the support assembly includes two adjacently installed connecting supports 410, and two rollers 431 are respectively installed on the two connecting supports 410. Figure 6 The connecting support 410 includes a connecting plate 411 and two ear plates 412 vertically fixed to the connecting plate 411. The two ends of the roller 431 are respectively connected to the two ear plates 412. The top of the second movable cover 131 is fixed with a mounting base 132. The mounting base 132 is provided with a second rope hole 133 for the steel wire rope 521 to pass through. The two connecting plates 411 are adjacently mounted on the mounting base 132. The opposite sides of the two connecting plates 411 are provided with a half hole for passing the rope. The two half holes for passing the rope are combined into a first rope hole 413. The connecting plate 411 and the mounting base 132 are connected and installed by a plurality of fasteners. By designing the support assembly as two connecting supports 410, the steel wire rope can be passed through the second rope hole 133 first, and then the connecting support 410 is installed. The roller 431 is pre-installed on the connecting support 410.

[0063] The first rope hole 413 and the second rope hole 133 are both opposite to the rope threading channel 401. With this design, rainwater falling from other positions to the area outside the rope threading channel 401 is difficult to flow into the rain cover shell through the first rope hole 413 and the second rope hole 133.

[0064] like Figure 6As shown, the roller 431 is installed on the connecting support 410 through the rotating assembly 420. The rotating assembly 420 includes a spindle 421 and a third sleeve 424. The spindle 421 passes through the two ear plates 412 of the connecting support 410 and is fixed. The end of the spindle 421 is pressed against one of the ear plates 412, and the other end is tightened with a nut. The third sleeve 424 is sleeved on the spindle 421, and the roller 431 is sleeved on the third sleeve 424. Two bearings 441 are arranged between the roller 431 and the third sleeve 424 to facilitate the rolling of the roller 431. Transparent covers 433 are respectively installed at both ends of the roller 431. The transparent covers 433 are fixed to the ends of the roller 431 with screws, and the transparent covers 433 do not contact the third sleeve 424. An annular stepped flange 425 is arranged in the middle of the third sleeve 424, and a bearing installation space for the bearing 441 to be installed is formed between the annular stepped flange 425 and the transparent cover 433.

[0065] It can be understood that the roller 431 and the third sleeve 424 rotate via the bearing 441, and the rotation performance is smooth. The roller 431 can rotate along with the movement of the wire rope, which helps to reduce the friction on the wire rope, thereby reducing the loss of the wire rope and increasing the service life of the wire rope.

[0066] Furthermore, a third oil injection channel 422 is provided inside the spindle 421, and the third oil injection channel 422 extends axially from the end of the spindle 421 and radially extends to the outer periphery at the middle of the spindle 421. The third sleeve 424 is provided with a plurality of radial through holes connected to the third oil injection channel 422 to connect the third oil injection channel with the bearing installation space. The injection port of the third oil injection channel 422 is provided at the end of the spindle 421, and the injection port of the third oil injection channel 422 is installed with a third oil seal 423. When lubricating, the third oil seal 423 can be removed, and then lubricating grease can be injected from the injection port of the third oil injection channel 422. The lubricating grease flows to the inner periphery of the third sleeve 424 through the third oil injection channel 422, and then flows to the bearing installation space through the radial through holes of the third sleeve 424, so that the bearing can be lubricated and maintained.

[0067] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
