Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel wire rope protection, and particularly relates to a steel wire rope rain cover device. BACKGROUND

[0002] The steel wire rope is an important component of a portal crane, and a hoisting mechanism is driven by a steel wire rope and a hoisting pulley to complete hoisting work. In general design of the portal crane, the hoisting mechanism is generally located in a machine room, and the machine room has heat preservation and rainproof functions. However, the steel wire rope needs to pass through the top of the machine room to be connected with the hoisting pulley. In the hoisting process, the steel wire rope inevitably interferes with the top of the machine room, so a hole needs to be opened in the top of the machine room to ensure the passability of the steel wire rope. In order to ensure the rainproof performance of the machine room, a steel wire rope rain cover device needs to be added.

[0003] The existing steel wire rope rain cover device often adopts a fixed rain cover or a single-direction swing rain cover. In the hoisting process of the steel wire rope, the steel wire rope swings left and right when being wound by a winding drum, and moves forward and backward when the winding layer increases. Therefore, the fixed rain cover and the single-direction swing rain cover cannot meet the use requirement, and may cause the steel wire rope to be stuck and abraded, thereby affecting the normal use of the crane.

[0039] Reference will now be made to the drawings Figures 1 to 10 , the embodiment describes a steel wire rope rain cover device, comprising a rain cover shell 100 and an outlet part 400.

[0040] As Figures 1 to 4 shown, the rain cover shell 100 comprises a fixed cover 111, a first movable cover 121 and a second movable cover 131. Among them, referring to Figure 9 , the fixed cover 111 is fixedly arranged, specifically welded on the top of the machine room 511, which ensures the water tightness of the bottom of the rain cover shell 100 and the machine room 511.

[0041] The lower part of the first movable cover 121 is hinged to the upper part of the fixed cover 111 through a first hinge part with a first axis 201, and the lower part of the second movable cover 131 is hinged to the upper part of the first movable cover 121 through a second hinge part with a second axis 301, the first axis 201 and the second axis 301 are not coplanar, 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, the first space, the second space and the third space are in communication with each other.

[0042] The outlet part 400 is used for the steel wire rope to pass out, which is arranged on the top of the second movable cover 131, that is, referring to Figure 10The steel wire rope 521 passes through the first space, the second space and the third space in turn after passing out of the top of the machine room 511, and then passes out of the outlet component 400. In the prior art, a through hole is formed in the top of the machine room 511 for the steel wire rope to pass out, which will not be described herein.

[0043] It can be understood that the steel wire rope 521 wound on the reel swings left and right and forward and backward, and the outlet component 400 arranged at the top of the second movable cover 131 moves along with the steel wire rope 521. The second movable cover 131 can swing relative to the first movable cover 121 about the second axis 301, and the first movable cover 121 can swing relative to the fixed cover 111 about the first axis 201. The first axis 201 and the second axis 301 are not coplanar, that is, the swinging direction of the first movable cover 121 is different from the swinging direction of the second movable cover 131. Finally, the second movable cover 131 can swing along with the outlet component 400. In this way, the inclination angle of the rain cover housing is matched with the steel wire rope, and the abrasion between the steel wire rope and the rain cover housing is reduced. In the embodiment, the steel wire rope rain cover device can better adapt to the swinging of the steel wire rope in multiple directions, and can avoid rainwater from entering the fixed cover when following the swinging of the steel wire rope. The waterproof performance of the rain cover housing is guaranteed, and the damage of the rain cover caused by the forward and backward and left and right swinging of the steel wire rope during the winding process of the reel can be avoided. The steel wire rope rain cover device of the embodiment can improve the service life of the steel wire rope, has a rainproof effect on the machine room, and protects the steel wire rope in the reel from being soaked in rainwater, thereby preventing the emulsification of the steel wire rope and protecting the lubricating layer.

[0044] As shown in Figure 1 , the rain cover housing 100 is inclined as a whole. The bottom of the fixed cover 111 is designed to have a bevel, and the rain cover housing 100 is welded to the machine room 511, so that the rain cover housing 100 is inclined as a whole.

[0045] Referring to Figure 1 and Figure 2 , the fixed cover 111 and the first movable cover 121 of the embodiment are both square tubes. The lower opening of the first movable cover 121 is arranged at the upper opening of the fixed cover 111, so that the upper opening of the fixed cover 111 is not exposed to the outside, thereby avoiding rainwater from entering the inside of the fixed cover 111. It is to be supplemented that the first movable cover 121 is provided with a maintenance cover, and the maintenance cover is installed on the first movable cover 121 by using fasteners.

[0046] As shown in Figure 3 , the first hinge part includes two first hinge assemblies 200 arranged at the left and right sides of the lower opening of the first movable cover 121. The first axis 201 is arranged in the left-right direction. The left and right sides of the lower opening of the first movable cover 121 are hingedly connected to the left and right sides of the upper opening of the fixed cover 111 by the first hinge assemblies 200. Figure 2For understanding, the first movable cover 121 swings back and forth relative to the fixed cover 111 along a first axis 201. The maximum swing angle a of the first movable cover 121 can be adjusted according to the variation range of the steel wire rope, and the size of the first movable cover 121 and the fixed cover 111 and the gap therebetween can be adjusted.

[0047] Figure 7 Only the sectional structure of one of the first hinge assemblies 200 is shown, and the other one can be arranged according to the symmetrical structure. Specifically, as shown in Figure 7 The first hinge assembly 200 includes a first pin shaft 211, a first shaft sleeve 221, a first washer 231, and a first pin 232. The first shaft 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 shaft hole for the first shaft sleeve 221 to pass through, and the first movable cover 121 has a second shaft hole for the first shaft sleeve 221 to pass through. Both the first shaft hole and the second shaft hole are slightly larger than the outer diameter of the first shaft sleeve 221, which can ensure that the first movable cover 121 and the fixed cover 111 can rotate relative to the shaft sleeve 221. The first pin shaft 211 penetrates the first shaft sleeve 221, and the end of the first pin shaft 211 abuts against one end of the first shaft sleeve 221. The first washer 231 penetrates the first pin shaft 211 and abuts against the other end of the first shaft sleeve 221. The first pin 232 is fixed to the end of the first pin shaft 211 to prevent the first washer 231 from sliding out, as shown in Figure 7 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, ensuring that the shaft first shaft sleeve 221 does not slide out.

[0048] In addition, the first pin shaft 211 is internally provided with a first oil injection channel 212, which extends axially from the end of the first pin shaft 211 and radially extends to the outer periphery at the middle part of the first pin shaft 211. The injection inlet of the first oil injection channel 212 is arranged at the end of the first pin shaft 211, and the first oil seal 213 is installed at the injection inlet of the first oil injection channel 212. When lubricating, the first oil seal 213 can be removed, and then the lubricating grease is injected from the injection inlet 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 communication holes at the middle position, and the lubricating grease can flow to the outer periphery of the first shaft sleeve 221 from the communication holes. 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 the embodiment shows the specific structure of the first hinge part, and in other embodiments, other structures can also 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 and a first pin, which can also realize the function of hinge, but the rotation performance is not as smooth as the embodiment.

[0050] The fixed cover 111 is provided with a first pad plate 112 and a second pad plate 113 on the inner and outer sides of the side wall at the position of the first shaft hole, and the first movable cover 121 is provided with a third pad plate 122 and a fourth pad plate 123 on the inner and outer sides of the side wall at the position of the second shaft hole, so that the first movable cover 121 and the fixed cover 111 can rotate relative to the first shaft sleeve 221, and the side wall of the first movable cover 121 and the side wall of the fixed cover 111 can be prevented from being worn.

[0051] Referring to Figure 3 and Figure 4 , the upper part of the second movable cover 131 is in the shape of a tapered cylinder, the lower part of the second movable cover 131 is in the shape of a square cylinder, and the lower cover of the second movable cover 131 covers 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. It should be further pointed out that the shape of the second movable cover 131 is difficult to manufacture integrally, and those skilled in the art can adopt the method of making it in half and then connecting it with fasteners,

[0052] As shown in Figure 1 , the second hinge part includes two second hinge assemblies 300 arranged on the front and rear sides of the lower opening of the second movable cover 131, and the second axis 301 is arranged obliquely in the front-rear direction, Figure 2 It can be seen that since the first movable cover 121 and the fixed cover 111 will swing in the front-rear 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 and change around the first axis 201 in the front-rear direction, but the second axis 301 is always arranged in the front-rear direction. As for whether the direction of the second axis 301 is horizontal or oblique, 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 hingedly connected to the front and rear sides of the upper opening of the first movable cover 121 through the second hinge assemblies 300, and in combination with Figure 4 , it can be 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 range of the steel wire rope, and the size of the second movable cover 131 and the first movable cover 121 and the gap therebetween can be adjusted.

[0054] Figure 8 Only the sectional structure of one of the second hinge assemblies 300 is shown, and the other can be arranged in a symmetrical structure. Specifically, as shown in the figure, Figure 8 The second hinge assembly 300 includes a second pin shaft 311, a second shaft sleeve 321, a second washer 331, and a second pin 332. The second shaft 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 shaft sleeve 321 to pass through, and the second movable cover 131 has a fourth shaft hole for the second shaft sleeve 321 to pass through. The second pin shaft 311 penetrates the second shaft sleeve 321, with one end of the second pin shaft 311 abutting against one end of the second shaft sleeve 321. The second washer 331 penetrates the second pin shaft 311 and abuts against the other end of the second shaft sleeve 321. The second pin 332 is fixed to the end of the second pin shaft 311 to prevent the second washer 331 from sliding out, as shown in the figure. Figure 8 As shown in the figure, 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, ensuring that the shaft second shaft sleeve 321 does not slide out.

[0055] In addition, the second pin shaft 311 is internally provided with a second oil injection channel 312, which 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 inlet of the second oil injection channel 312 is provided at the end of the second pin shaft 311, and the second oil seal 313 is installed at the injection inlet of the second oil injection channel 312. When lubricating, the second oil seal 313 can be removed, and then the lubricating grease is injected from the injection inlet 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 communication holes at the middle position, and the lubricating grease can flow to the outer periphery of the second shaft sleeve 321 from the communication holes. 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 the 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 to realize the hinge function, but the rotation performance is not as smooth as the embodiment.

[0057] The first movable cover 121 is provided with the fifth pad plate 124 and the sixth pad plate 125 located on 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 the seventh pad plate 134 and the eighth pad plate 135 located on 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, and 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 steel wire rope rain cover device adopts a rubber plate for the rain cover shell, and the rainproof performance is poor. After a period of use, the rubber plate is prone to aging, affecting the rainproof performance. The rubber plate directly contacts the steel wire rope, which greatly wears the steel wire rope and affects the service life of the steel wire rope. At the same time, the weight of the rain cover shell is too large, and the pressure on the steel wire rope is too large. When the force on the steel wire rope is small, the rain cover may not be driven to move synchronously, which also aggravates the wear of the steel wire rope.

[0059] In the embodiment, the rain cover shell is made of aluminum alloy, which is light in weight and easy to install. The fixed cover 111 is welded on the top of the machine house 511. The rain cover shell made of aluminum alloy is light in weight. When the tension of the steel wire rope is small when the steel wire rope is in an empty state, the first movable cover and the second movable cover can also swing with the steel wire rope, avoiding the situation that the first movable cover and the second movable cover cannot be driven to return.

[0060] Specifically, in combination with Figure 5 and Figure 6 , the outlet component 400 includes a support assembly fixed on 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-shaped groove 432. The two rollers 431 are arranged adjacent to each other to form a rope passing channel 401 with a size matching the steel wire rope 521 between the two arc-shaped grooves 432. The coupling support 410 is provided with a first rope hole 413 for the steel wire rope 521 to pass through.

[0061] It can be understood that at present, the export component is all in the use of four roller shafts to assist the steel wire rope to move, but the gap between the roller shaft and the steel wire rope is large, even if through adjustment, the gap is difficult to adjust to the ideal range, rainwater is easy to enter into the rain cover shell from the gap position, the rain cover shell is in communication with the machine room inside, and rainwater will enter into the machine room. In the embodiment, the inner recess in the middle of the roller 431 is provided to form an arc-shaped groove 432, after two adjacent rollers 431 are installed, a rope passing channel 401 is formed between the two arc-shaped grooves 431, the steel wire rope 521 passes through the rope passing channel 401, in the process of winding the steel wire rope on the drum, the friction between the steel wire rope 521 and the roller 431 is in the form of rolling friction, which can greatly reduce the friction and friction loss of the steel wire rope 521, and the arc-shaped groove 432 is formed by the inner recess in the middle of the roller 431, only two rollers 432 are needed to cooperate to form the rope passing channel 401, the rope passing channel 401 is slightly larger than the outer diameter of the steel wire rope, and the gap between the steel wire rope 521 and the roller 431 is small, which can better play the role of waterproof and rainproof. Those skilled in the art can refer to the above description of the rope passing channel in the specific application. Figure 5 The size of the rope passing channel can be designed to be the outer diameter size of the steel wire rope plus the thickness size of the coated lubricating grease, in this way, it is difficult for rainwater to enter into the rain cover shell from the gap.

[0062] Specifically, as shown in Figure 5 , the support assembly includes two adjacent coupling supports 410, and two rollers 431 are respectively installed on the two coupling supports 410.

Among them, the connecting plate 411 is connected and installed with the mounting base 132 through a plurality of fasteners, by designing the support assembly as two coupling supports 410, the steel wire rope can be first passed through the second rope hole 133, and then the coupling support 410 is installed, wherein the roller 431 is pre-installed on the coupling support 410.

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

[0064] As shown in Figure 6As shown, the roller 431 is mounted on the connecting support 410 through a rotating assembly 420, the rotating assembly 420 comprises a mandrel 421 and a third shaft sleeve 424, the mandrel 421 penetrates through the two ear plates 412 of the connecting support 410 and is fixed, the end of the mandrel 421 abuts against one of the ear plates 412, and the other end is tightened by a nut. The third shaft sleeve 424 is sleeved on the mandrel 421, the roller 431 is sleeved on the third shaft sleeve 424, and two bearings 441 are arranged between the roller 431 and the third shaft sleeve 424, so that the roller 431 can roll conveniently, and the roller 431 is provided with a transparent cover 433 at each end, the transparent cover 433 is fixed on the end of the roller 431 by screws, and the transparent cover 433 does not contact the third shaft sleeve 424. The middle part of the third shaft sleeve 424 is provided with an annular stepped flange 425, and the annular stepped flange 425 and the transparent cover 433 form a bearing mounting space for mounting the bearing 441.

[0065] It can be understood that the roller 431 and the third shaft sleeve 424 rotate through the bearing 441, the rotating performance is smooth, the roller 431 can rotate following the movement of the steel wire rope, which helps to reduce the friction force suffered by the steel wire rope, thereby reducing the wear of the steel wire rope and prolonging the service life of the steel wire rope.

[0066] Further, the inside of the mandrel 421 is provided with a third oil injection channel 422, the third oil injection channel 422 extends axially from the end of the mandrel 421 and extends radially to the outer periphery in the middle part of the mandrel 421, the third shaft sleeve 424 is provided with a plurality of radial through holes in communication with the third oil injection channel 422, so as to communicate the third oil injection channel with the bearing mounting space, the injection inlet of the third oil injection channel 422 is arranged at the end of the mandrel 421, and the third oil seal 423 is mounted at the injection inlet of the third oil injection channel 422. When lubricating, the third oil seal 423 can be removed, then the lubricating grease is injected from the injection inlet of the third oil injection channel 422, the lubricating grease flows to the inner periphery of the third shaft sleeve 424 through the third oil injection channel 422, and then flows to the bearing mounting space through the radial through holes of the third shaft sleeve 424, so as to lubricate the bearing.
