Description

Technical Field

[0001] The present invention relates to the technical field of monorail cranes, in particular to a suspension device for a monorail crane and a crane thereof. Background Art

[0002] A monorail crane refers to a transportation equipment that runs on a suspended monorail and consists of a drive vehicle or a traction vehicle (for wire rope traction), a brake vehicle, a carrying vehicle, etc. It is often used to transport goods and personnel in special occasions such as coal mine tunnels, road tunnels, and railway tunnels. The main advantages of monorail crane transportation are: first, the monorail crane has a small cross-section and high utilization rate of the tunnel cross-section space; second, it can be used for continuous non-transfer transportation in horizontal and inclined tunnels. Its transported load is not limited by the bottom plate conditions and can run on various vertical curves, horizontal curves and complex curves; third, it can complete auxiliary transportation from the mining area yard to the working face without transfer, and can be used for auxiliary transportation operations connecting the main transportation tunnels and mining area tunnels.

[0003] In the application document of a monorail crane and a suspension device for the monorail crane proposed with application number 201810411045.6, two crane wheels are directly placed on the monorail, and the outer circle of the crane wheels can be pressed against the monorail by the gravity of the monorail crane. In this way, there is no need to set up an additional power device, that is, the crane wheels roll by friction.

[0004] However, since the I-steel is exposed to a complex environment for a long time, impurities are easily accumulated inside the I-steel, affecting the rotation of the roller. In addition, the accumulated impurities cause a large contact area between the I-steel and the roller, which in turn causes a large friction between the I-steel and the roller, resulting in serious wear of the I-steel and the roller, and a short service life of the roller and the I-steel, which in turn causes a short service life of the suspension device of the monorail crane. Therefore, it is necessary to provide a suspension device for a monorail crane and a crane thereof to solve the above technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0034] Example 1

[0035] like Figure 1-Figure 5 As shown, a suspension device for a monorail crane includes a moving frame 1 and an I-shaped track 3. Four rollers 2 are installed inside the moving frame 1, and the rollers 2 are all inside the I-shaped track 3. A moving member 4 is installed at the end of the moving frame 1. The moving member 4 includes a driving shaft 401, a drive shaft 402, a rotating shaft 403, a reciprocating cleaning member 404, an anti-accumulation member 405, a fixing box 406, a lubricating member 407, and a continuous clamping member 409.

[0036] The end of the walking part 4 passes through the mobile frame 1 and is fixedly connected to a driving shaft 401. The inside of the driving shaft 401 is connected to a driving shaft 402 through a one-way bearing. The end of the mobile frame 1 is rotatably connected to four rotating shafts 403. Four reciprocating cleaning parts 404 are provided at the end of the mobile frame 1. Anti-accumulation parts 405 are provided at the end of the reciprocating cleaning parts 404. Four fixed boxes 406 are installed on the outside of the mobile frame 1 by screws. Lubricating parts 407 are installed at the end of the fixed box 406. A continuous clamping part 409 is provided at the bottom of the mobile frame 1 to enable the suspension device to move quickly and avoid the problem of the suspension device being stuck.

[0037] The two driving shafts 401 on one side of the mobile frame 1 form a group, and the two reciprocating cleaning parts 404 on one side of the mobile frame 1 form a group. The one-way bearings connected between a group of driving shafts 402 and the rotating shaft 403 rotate in opposite directions, so that when the suspension device moves in two different directions, it is ensured that only one reciprocating cleaning part 404 in a group is running, and the other reciprocating cleaning part 404 is not running.

[0038] The reciprocating cleaning member 404 includes a driving gear connecting mechanism 4041, a driving rod 4042, a connecting rod 4043 and a cleaning frame 4044;

[0039] The driving shaft 402 is connected to the adjacent rotating shaft 403 via a driving gear connecting mechanism 4041. One end of the driving gear connecting mechanism 4041 is rotatably connected to a driving rod 4042. One end of the driving rod 4042 is rotatably connected to a connecting rod 4043. One end of the connecting rod 4043 is fixedly connected to a cleaning frame 4044. The cleaning frame 4044 is inside the I-shaped track 3. When the suspension device moves outside the I-shaped track 3, the roller 2 rotates, and the rotation of the roller 2 drives the driving shaft 401 to rotate. At this time, it is connected through two one-way bearings with opposite rotation directions. At this time, the driving shaft 401 can drive the two driving shafts 402 at one end to rotate. The two driving shafts 402 at the other end cannot rotate due to the limitation of the one-way bearing. At this time, the driving rod 4042 can be driven to rotate through the connection of the driving gear connecting mechanism 4041. Through the rotation connection between the driving rod 4042 and the connecting rod 4043, when the driving rod 4042 rotates, the connecting rod 4043 can be driven to move, thereby realizing the movement of the cleaning frame 4044 to clean the inner wall of the I-shaped track 3. By continuously rotating the driving gear connecting mechanism 4041, the cleaning frame 4044 can be driven to move back and forth, thereby improving the cleaning effect of the inner wall of the I-shaped track 3, facilitating the accumulation of impurities on the inner wall of the I-shaped track 3, and affecting the walking of the roller 2.

[0040] The driving gear connection mechanism 4041 includes two driving gears, which are meshed and connected. The ends of the driving shaft 402 and the rotating shaft 403 are fixedly connected to the driving gears. The driving rod 4042 is rotatably connected to one end of a driving gear, which facilitates the rotation of the driving rod 4042 and the movement of the cleaning rack 4044.

[0041] The cleaning frame 4044 includes a fixing frame and a hard rubber plate. The end of the hard rubber plate is provided with an inclined angle. The connecting rod 4043 is fixedly connected to the fixing frame by screws to avoid damage to the inner wall of the I-shaped track 3 when cleaning the I-shaped track 3. The inclined angle facilitates the cleaning of the inner wall of the I-shaped track 3, thereby improving the cleaning effect.

[0042] The anti-accumulation member 405 includes a fan blade 4051, a guide tube 4052 and an air outlet 4053;

[0043] A fan blade 4051 is fixedly sleeved on the outside of one end of the driving shaft 402, and four guide tubes 4052 are fixedly connected to the outside of the movable frame 1. A plurality of air outlet holes 4053 are opened at one end of the guide tube 4052. When the driving shaft 402 rotates, the fan blade 4051 is driven to rotate, so that the wind generated by the fan blade 4051 enters the inside of the guide tube 4052, and then is discharged through the air outlet holes 4053 to blow away the cleaned impurities and blow the impurities out from the inside of the I-type track 3, so as to avoid the problem of the accumulation of cleaned impurities affecting the movement of the roller 2.

[0044] One end of the guide tube 4052 is fixedly mounted on one end of the connecting rod 4043, with the air outlet 4053 facing the inside of the I-shaped track 3. One end of the four guide tubes 4052 is located outside the four fan blades 4051, so that one end of the guide tube 4052 can move with the movement of the connecting rod 4043, which is convenient for guiding the wind and ensuring continuous blowing during the cleaning process.

[0045] Example 2

[0046] Based on the first embodiment, Figure 6-Figure 8 As shown, the lubricating member 407 includes a return spring 4071, a return frame 4072, a push plate 4073, an oil outlet pipe 4074, a rotating cylinder 4075 and a sponge 4076;

[0047] Both ends of one side of the fixed box 406 are welded with return springs 4071, one end of the two return springs 4071 is connected by a return frame 4072, and one end of the return frame 4072 is installed with a push plate 4073 by screws. One end of the bottom of the fixed box 406 is fixedly connected to an oil outlet pipe 4074, and both ends of one side of the oil outlet pipe 4074 are rotatably connected to a rotating cylinder 4075. A sponge 4076 is adhered to the outside of the rotating cylinder 4075. Lubricating oil is added to the inside of the fixed box 406. When the cleaning frame 4044 moves back and forth, the cleaning frame 4044 will contact the return frame 4072 and push the return frame 4072 to move, causing the return spring 4071 to compress. When 72 moves, it drives the push plate 4073 to move, squeezing the lubricating oil inside the fixed box 406, so that the lubricating oil enters the oil outlet pipe 4074. At this time, the sponge 4076 will absorb the oil outlet pipe 4074. As the suspension device moves, the rotating cylinder 4075 will rotate with the movement of the suspension device. At this time, the sponge 4076 that absorbs the lubricating oil will be squeezed, so that the lubricating oil is smeared on the inner wall of the I-type track 3, which can reduce the friction between the roller 2 and the inner wall of the I-type track 3, reduce the wear of the roller 2 and the I-type track 3, and extend the service life of the suspension device. In addition, the lubrication cost of the I-type track 3 can be reduced by lubricating the I-type track 3 in sections.

[0048] The push plate 4073 is located inside the fixed box 406 , and the inner wall of the fixed box 406 is in contact with the outer side of the push plate 4073 , which facilitates the pushing of the lubricating oil so that the lubricating oil enters the oil outlet pipe 4074 .

[0049] The positions of the reset frame 4072 and the connecting rod 4043 correspond to each other, and the rotating cylinder 4075 rolls on the inner wall of the I-shaped track 3, which is convenient for pushing the reset frame 4072 to move, and can drive the rotating cylinder 4075 to rotate when the suspension device moves to achieve the application of lubricating oil.

[0050] A guide member 408 is installed at one end of the bottom of the oil outlet pipe 4074. The guide member 408 includes a partition frame 4081, a spring telescopic column 4082 and a closing plate 4083.

[0051] A partition frame 4081 is fixedly connected to the inside of the oil outlet pipe 4074, and spring telescopic columns 4082 are installed at both ends of the partition frame 4081 by screws. A closing plate 4083 is installed at one end of the spring telescopic column 4082 by screws. When the lubricating oil is squeezed, the lubricating oil pushes the closing plate 4083, causing the spring telescopic column 4082 to compress, opening the end of the partition frame 4081, and allowing the lubricating oil to enter the oil outlet pipe 4074. When the connecting rod 4043 is not in contact with the reset frame 4072, the reset spring 4071 and the spring telescopic column 4082 are stretched, pushing the closing plate 4083 to move, and then closing the oil outlet pipe 4074, which can prevent the lubricating oil inside the oil outlet pipe 4074 from flowing back.

[0052] The end of the closing plate 4083 is a conical cylinder, and an oil inlet hole is opened on the end face of the conical cylinder. The outer diameter of the closing plate 4083 is larger than the oil inlet hole, which is convenient for separating the lubricating oil so that the lubricating oil enters the top and bottom of the oil outlet pipe 4074 respectively, and is convenient for closing the end of the conical cylinder.

[0053] Example 3

[0054] On the basis of embodiment 1 or 2, Figure 9 As shown, the continuous clamping member 409 includes a belt connecting mechanism 4091, a rotating shaft 4092, a rubber tube 4093, a driving gear 4094, a driving gear rod 4095 and a clamping plate 4096;

[0055] The outer sides of the two rotating shafts 403 are connected to a belt connecting mechanism 4091 through a one-way bearing. A rubber tube 4093 is rotatably connected to one end of the belt connecting mechanism 4091. A rotating shaft 4092 is provided inside the rubber tube 4093. The rotating shaft 4092 is rotatably connected to the end of the mobile frame 1. A driving gear 4094 is fixedly sleeved on the outer side of the rotating shaft 4092. Both ends of the driving gear 4094 are meshed and connected to a driving gear rod 4095. The driving gear rod 4095 is slidably connected to one end of the mobile frame 1 through a T-block. The bottom of the driving gear rod 4095 The clamping plate 4096 is installed at the bottom by screws. After the personnel hangs the workpiece on the bottom of the mobile frame 1, when the suspension device moves, when the roller 2 rotates forward, the roller 2 rotates to drive the rotating shaft 403 to rotate. Through the connection of the belt connecting mechanism 4091 and the connection of the one-way bearing, one belt connecting mechanism 4091 can rotate with the rotation of the rotating shaft 403, and the other belt connecting mechanism 4091 cannot rotate with the rotation of the rotating shaft 403. At this time, the rotation of the belt connecting mechanism 4091 drives the rubber cylinder 4093 to rotate. The rotation of the rotating shaft 4092 is achieved by the friction between the rubber cylinder 4093 and the rotating shaft 4092, and the rotation of the rotating shaft 4092 drives the driving gear 4094 to rotate. The rotation of the driving gear 4094 drives the two driving gear rods 4095 to move, so that the two clamping plates 4096 are close to each other to clamp the workpiece. As the suspension device moves and clamps the workpiece, the driving gear 4094 and the driving gear rod 4095 are in a stuck state. At this time, the friction between the rubber cylinder 4093 and the rotating shaft 4092 The friction force is smaller than the meshing force between the driving gear 4094 and the driving gear rod 4095. At this time, the rotation of the belt connection mechanism 4091 cannot drive the rotating shaft 4092 to rotate, but it can always apply axial force to the rotating shaft 4092, so that the clamping plate 4096 always clamps the workpiece to ensure the stability of the workpiece during transportation. After the workpiece is transported to the designated position, the personnel manually move the clamping plate 4096 to release the workpiece. Conversely, when the suspension device moves in the opposite direction, another clamping plate 4096 can be used to clamp the workpiece.

[0056] An anti-slip plate is bonded to the end face of the clamping plate 4096, and a plurality of anti-slip grooves are provided on the end face of the anti-slip plate. There are four clamping plates 4096, and two opposing clamping plates 4096 form a group. The two groups of clamping plates 4096 are staggered to facilitate clamping of the workpiece and avoid damage to the workpiece.

[0057] The two belt connection mechanisms 4091 are respectively located on both sides of the movable frame 1 . The two belt connection mechanisms 4091 are staggered and can clamp the workpiece when the suspension device moves in different directions.

[0058] Example 4

[0059] On the basis of embodiment 1, 2 or 3, Figure 10 As shown, a monorail crane includes at least two suspension devices and two driving vehicles 5. The suspension devices are connected to each other and the suspension devices and the driving vehicles 5 are connected by driving rods. The driving rods are all rotationally connected to the suspension devices and the driving vehicles 5. The suspension devices and the driving vehicles 5 are both slidingly connected to the outside of the I-type track 3.

[0060] The driving vehicle 5 drives the mobile frame 1 and the roller 2 to move on the I-shaped track 3. During the movement of the mobile frame 1 and the roller 2, the driving shaft 401 and the driving shaft 402 at one end of the mobile frame 1 are driven to rotate, thereby driving the reciprocating cleaning member 404 at one end to operate, thereby cleaning the inside of the I-shaped track 3, ensuring the cleanliness of the inside of the I-shaped track 3, facilitating the rolling of the roller 2, and avoiding the problem of the roller 2 getting stuck when rolling. While removing impurities, the impurities are blown away by the anti-accumulation member 405 to avoid the problem of impurities accumulating inside the I-shaped track 3, ensuring the operation of the suspension device. While cleaning the inner wall of the I-shaped track 3, the roller 2 is lubricated to reduce the friction between the roller 2 and the I-shaped track 3, thereby reducing the wear of the I-shaped track 3 and the roller 2, and extending the service life of the suspension device. As the mobile frame 1 moves, the use of the continuous clamping member 409 can clamp the workpiece during transportation, ensuring the stability of the workpiece during transportation, thereby ensuring the stability of the suspension device transportation and ensuring the stable movement of the suspension device.
