Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and particularly relates to a pneumatic crane. Background Art

[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as an overhead crane, gantry crane, crane, etc., in the current industrial production process, the transfer and loading / unloading of products often rely on cranes. Cranes are generally divided into electric, hydraulic, and pneumatic types. For light cranes in some specific occasions, a fully pneumatic mode is often adopted, and among them, a pneumatic tower crane is a type of tower crane.

[0003] However, for existing pneumatic tower cranes, in order to improve the wind resistance of the tower crane itself, the winch of the pneumatic tower crane is in an exposed state to the outside. Then, when it rains outside, rainwater will come into contact with the steel wire rope on the winch, which will cause the steel wire rope to rust. If the rust on the steel wire rope is not treated, the rust on the steel wire rope will expand, reducing the load-bearing capacity of the steel wire rope, and thus affecting the use of the tower crane.

[0004] However, the current rust removal of the steel wire rope is usually to wipe the surface of the steel wire rope manually. Due to the high height of the tower crane, the length of the steel wire rope is relatively long, so manual rust removal is very troublesome, with low efficiency and a large burden on the workers. Summary of the Invention

[0005] The purpose of the present invention is to at least solve one of the technical problems existing in the prior art, and provide a pneumatic crane that can solve the problem of difficult treatment of rust on the steel wire rope.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A pneumatic crane, comprising a pneumatic crane body, a fixed frame, a motor, a wire roller, a steel wire rope, a fixed rod, and a wire arranging wheel. Two sliding rods are fixedly connected to the inner wall of the fixed frame. Rotating grooves are formed on the left and right sides of the wire arranging wheel. Two "L"-shaped connecting rods are slidably connected to the inner walls of the two rotating grooves. Rotating balls are embedded at the rear ends of the two connecting rods. The surfaces of the two rotating balls are respectively slidably connected to the inner walls of the two rotating grooves. A cleaning mechanism is provided at one end of the two connecting rods away from the wire arranging wheel.

[0007] Preferably, the output end of the motor penetrates through the right side of the fixed frame and is fixedly connected to the wire roller. The left and right ends of the wire roller are respectively rotatably connected to the left and right sides of the inner wall of the fixed frame. The left and right ends of the fixed rod are respectively fixedly connected to the left and right sides of the inner wall of the fixed frame. The inner ring of the wire arranging wheel is rotatably connected to the surface of the fixed rod. The rear end of the steel wire rope is arranged on the surface of the wire roller. One end of the steel wire rope away from the wire roller is slidably connected to the surface of the wire arranging wheel.

[0008] Preferably, the cleaning mechanism includes a first cleaning shell and a second cleaning shell. The first cleaning shell and the second cleaning shell are respectively movably connected to the front ends of two connecting rods. The surfaces of the two sliding rods penetrate through the surfaces of the first cleaning shell and the second cleaning shell. The interiors of the first cleaning shell and the second cleaning shell are both slidably connected to the surfaces of the two sliding rods. Connecting grooves are respectively formed on the upper and lower sides of the surface of the first cleaning shell. A through hole in the shape of half an hourglass is formed on the surface of the first cleaning shell. The inner wall of the through hole is slidably connected to the surface of the steel wire rope. A steel brush is fixedly connected to the inner wall of the through hole. Two chutes are respectively formed on the front and rear sides of the inner wall of the through hole and are arranged obliquely relative to each other.

[0009] Preferably, a collection groove communicating with the two chutes is formed on the lower side of the surface of the first cleaning shell.

[0010] Preferably, a clamping groove is formed on the front side of the inner wall of the connecting groove. A clamping block is slidably connected to the inner wall of the clamping groove. The right side of the clamping block is a slope. A pull rod penetrating through the surface of the first cleaning shell is fixedly connected to the front side of the clamping block.

[0011] Preferably, an elastic component movably sleeved on the surface of the pull rod and fixedly connected to the front side of the clamping block is fixedly connected to the inner wall of the clamping groove at the end far from the clamping block.

[0012] Preferably, "convex"-shaped clamping rods are respectively fixedly connected to the upper and lower sides of the surface of the second cleaning shell. The surfaces of the two clamping rods are respectively slidably connected to the inner walls of the two connecting grooves.

[0013] Preferably, through holes, steel brushes, chutes, and collection grooves which are arranged in a mirror image of the first cleaning shell are also provided on the surface of the second cleaning shell.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] (1) For this pneumatic crane, through the arrangement of the cleaning mechanism, rust on the steel wire rope can be cleaned while the crane is in use, so that the operator does not need to clean the steel wire rope separately, thereby reducing the labor intensity of the operator, lightening the burden on the operator. At the same time, the cleaning speed of the device is the same as the speed of the steel wire rope, thus greatly improving the cleaning efficiency of the device for the steel wire rope.

[0016] (2) For this pneumatic crane, through the hourglass-shaped arrangement of the through hole, rust on the steel wire rope can be collected to the greatest extent, avoiding the random splashing of rust, collecting the rust uniformly, and thus ensuring the working cleanliness of the device.

[0017] (3) The pneumatic crane, through the "convex" setting of the clamping rod and the inclined plane setting of the clamping block, enables the operator to complete the connection of the first cleaning shell and the second cleaning shell by simply inserting the two clamping rods into the two connecting grooves respectively, greatly reducing the connection difficulty of the device, enabling the operator to quickly connect the device, and thus improving the working efficiency of the operator.

[0018] (4) The pneumatic crane, through the setting of the rotating ball, reduces the friction between the connecting rod and the rotating groove, enabling the rotating ball to rotate in place inside the rotating groove under the tension of the connecting rod when the wire arranging wheel rotates, avoiding the situation where the connecting rod rotates following the wire arranging wheel, and at the same time preventing the two connecting rods from detaching from the rotating groove, so that the two connecting rods can move along with the movement of the wire arranging wheel, ensuring the smooth operation of the device.

[0019] (5) The pneumatic crane, through the setting of the pull rod, enables the operator to separate the first cleaning shell and the second cleaning shell by simply pulling the pull rod, so that the operator can quickly process the rust inside the collection tank, and thus improves the processing efficiency of the operator for the rust.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-2 , the present invention provides a technical solution: a pneumatic crane, including a pneumatic crane body 23, a fixed frame 1, a motor 2, a wire roller 3, a steel wire rope 4, a fixed rod 5, and a wire arranging wheel 6. The fixed frame 1 is fixedly connected to the crane body 23. The output end of the motor 2 penetrates through the right side of the fixed frame 1 and is fixedly connected to the wire roller 3. The left and right ends of the wire roller 3 are respectively rotatably connected to the left and right sides of the inner wall of the fixed frame 1. The left and right ends of the fixed rod 5 are respectively fixedly connected to the left and right sides of the inner wall of the fixed frame 1. The inner ring of the wire arranging wheel 6 is rotatably connected to the surface of the fixed rod 5. The rear end of the steel wire rope 4 is arranged on the surface of the wire roller 3. One end of the steel wire rope 4 away from the wire roller 3 is slidably connected to the surface of the wire arranging wheel 6. Thus, through the setting of the motor 2, power is provided for the rotation of the wire roller 3. Through the setting of the wire roller 3, a winding space is provided for the steel wire rope 4. Through the setting of the fixed rod 5, support is provided for the wire arranging wheel 6. Through the setting of the wire arranging wheel 6, the steel wire rope 4 can be evenly arranged on the surface of the wire roller 3.

[0034] Furthermore, when the motor 2 drives the wire roller 3 to rotate, the steel wire rope 4 is arranged on the surface of the wire roller 3 through the traction force of the wire roller 3 during rotation. At the same time, under the friction between the steel wire rope 4 and the wire arrangement wheel 6, the wire arrangement wheel 6 rotates on the surface of the fixed rod 5 and moves left and right, thereby ensuring that the device can evenly arrange the steel wire rope 4 on the surface of the wire roller 3.

[0035] Embodiment 2:

[0036] See also Figure 3 On the basis of the first embodiment, a rotating groove 12 is provided on both sides of the cable wheel 6, and two "L"-shaped connecting rods 10 are slidably connected to the inner walls of the two rotating grooves 12. The rear ends of the two connecting rods 10 are inlaid with rotating balls 11. The surfaces of the two rotating balls 11 are respectively slidably connected to the inner walls of the two rotating grooves 12. The diameter of the rotating balls 11 is larger than the opening size of the rotating grooves 12. Therefore, the two connecting rods 10 cannot be separated from the rotating grooves 12 by the setting of the rotating balls 11, so that the two connecting rods 10 can move with the movement of the cable wheel 6. , thereby ensuring the smooth operation of the device, a cleaning mechanism is provided at one end of the two connecting rods 10 away from the cable wheel 6, and the cleaning mechanism includes a first cleaning shell 8 and a second cleaning shell 7, and the first cleaning shell 8 and the second cleaning shell 7 are respectively movably connected to the front ends of the two connecting rods 10, and the inner wall of the fixed frame 1 is fixedly connected with two sliding rods 9, and the surfaces of the two sliding rods 9 both penetrate the surfaces of the first cleaning shell 8 and the second cleaning shell 7, and the interiors of the first cleaning shell 8 and the second cleaning shell 7 are slidably connected to the surfaces of the two sliding rods 9, and then through the setting of the two sliding rods 9, the first cleaning shell 8 The first cleaning shell 8 and the second cleaning shell 7 provide support and fix the first cleaning shell 8 and the second cleaning shell 7, so that the first cleaning shell 8 and the second cleaning shell 7 will not rotate along with the rotation of the wire arranging wheel 6, thereby ensuring the normal operation of the device. At the same time, through the setting of the rotating ball 11, the friction between the connecting rod 10 and the rotating groove 12 is reduced, so that the rotating ball 11 can rotate in place inside the rotating groove 12 when the wire arranging wheel 6 rotates under the pulling force of the connecting rod 10, avoiding the situation where the connecting rod 10 rotates along with the rotation of the wire arranging wheel 6, thereby ensuring the smooth operation of the device.

[0037] See also Figures 4-6, connection grooves 13 are provided on both the upper and lower sides of the surface of the first cleaning shell 8. The structures inside the two connection grooves 13 are the same. Therefore, only one of them will be described here. A clamping groove 18 is provided on the front side of the inner wall of the connection groove 13. A clamping block 15 is slidably connected to the inner wall of the clamping groove 18. The right side of the clamping block 15 is a slope. A pull rod 20 penetrating the surface of the first cleaning shell 8 is fixedly connected to the front side of the clamping block 15. An elastic component 19 fixedly connected to the front side of the clamping block 15 is movably sleeved on the surface of the pull rod 20. One end of the elastic component 19 away from the clamping block 15 is fixedly connected to the inner wall of the clamping groove 18. Clamping rods 16 in a "convex" shape are fixedly connected to both the upper and lower sides of the surface of the second cleaning shell 7. The surfaces of the two clamping rods 16 are respectively slidably connected to the inner walls of the two connection grooves 13.

[0038] Furthermore, a through hole 21 in a shape of half an hourglass is provided on the surface of the first cleaning shell 8. The inner wall of the through hole 21 is slidably connected to the surface of the steel wire rope 4. A steel brush 22 is fixedly connected to the inner wall of the through hole 21. Two pairs of chutes 14 are provided on the front and rear sides of the inner wall of the through hole 21 and are arranged obliquely relative to each other. A collection groove 17 communicating with the two chutes 14 is provided on the lower side of the surface of the first cleaning shell 8. The surface of the second cleaning shell 7 is also provided with a through hole 21, a steel brush 22, chutes 14, and a collection groove 17 that are mirror-image to those of the first cleaning shell 8.

[0039] When using the device, the surface of the steel wire rope 4 is pressed against the surface of the steel brush 22 on the first cleaning shell 8. Then, the two clamping rods 16 are respectively inserted into the two connection grooves 13. As the two clamping rods 16 are pushed forward, the protruding parts of the two clamping rods 16 respectively come into contact with the slopes of the two clamping blocks 15. Then, under the external pushing force, the protruding parts of the two clamping rods 16 respectively squeeze the slopes of the two clamping blocks 15. As a result, the surfaces of the two clamping blocks 15 respectively slide forward inside the two clamping grooves 18, causing the two elastic components 19 to be compressed. Then, the two pull rods 20 slide forward inside the first cleaning shell 8. When the protruding parts of the two clamping rods 16 disengage from the two clamping blocks 15, under the elastic force of the two elastic components 19, the two clamping blocks 15 and the two pull rods 20 return to their original states. Then, the two clamping blocks 15 respectively block the protruding parts of the two clamping rods 16, making it impossible to pull out the two clamping rods 16. Thus, the connection between the first cleaning shell 8 and the second cleaning shell 7 is completed. At this time, the through holes 21 on the first cleaning shell 8 and the second cleaning shell 7 clamp the surface of the steel wire rope 4. Through the "convex" shape of the clamping rod 16 and the slope of the clamping block 15, the operator only needs to insert the two clamping rods 16 into the two connection grooves 13 respectively to complete the connection between the first cleaning shell 8 and the second cleaning shell 7, greatly reducing the connection difficulty of the device and enabling the operator to quickly connect the device, thereby improving the working efficiency of the operator.

[0040] After the device connection is completed, when the crane is working, that is, when the steel wire rope 4 slides, friction occurs between the surface of the steel wire rope 4 and the surface of the steel brush 22, thereby erasing the rust on the surface of the steel wire rope 4. The wiped rust falls onto the conical surface of the through hole 21. Then, as the first cleaning shell 8 and the second cleaning shell 7 move on the sliding rod 9, the rust on the conical surface moves on the conical surface with the vibration generated when the device moves, and then falls into the collection tank 17 through the chute 14. Furthermore, due to the hourglass-shaped setting of the through hole 21, the rust on the steel wire rope 4 can be collected to the greatest extent, avoiding the random splashing of rust and collecting the rust uniformly, thereby ensuring the working cleanliness of the device. At the same time, through the setting of the cleaning mechanism, the rust on the steel wire rope is cleaned while the crane is in use, so that the operator does not need to clean the steel wire rope 4 separately, thereby reducing the labor intensity of the operator, lightening the burden of the operator. At the same time, the cleaning speed of the device is the same as the speed of the steel wire rope 4, thereby greatly improving the cleaning efficiency of the device for the steel wire rope 4.

[0041] When there is a lot of rust in the collection tank 17, the operator can pull the two pull rods 20, thereby driving the two clamping blocks 15 to slide forward inside the two clamping grooves 18 respectively, so that the two elastic components 19 are compressed. Since the two clamping blocks 15 no longer block the protrusions of the two clamping rods 16, at this time, the operator can directly separate the first cleaning shell 8 and the second cleaning shell 7, thereby being able to process the rust inside the collection tank 17. Furthermore, through the setting of the pull rod 20, the operator only needs to pull the pull rod 20 to separate the first cleaning shell 8 and the second cleaning shell 7, so that the operator can quickly process the rust inside the collection tank 17, thereby improving the processing efficiency of the operator for the rust.

[0042] Working principle: When using this device, the surface of the wire rope 4 is pressed against the surface of the steel brush 22 on the first cleaning shell 8. Then, the two clamping rods 16 are respectively inserted into the two connecting grooves 13. Under the external thrust, the protruding parts of the two clamping rods 16 respectively squeeze the inclined surfaces of the two clamping blocks 15, so that the two elastic components 19 are compressed, and then the two pull rods 20 slide forward inside the first cleaning shell 8. When the protruding parts of the two clamping rods 16 disengage from the two clamping blocks 15, under the elastic force of the two elastic components 19, the two clamping blocks 15 and the two pull rods 20 return to their original states, and then the two clamping blocks 15 respectively block the protruding parts of the two clamping rods 16, thus completing the connection between the first cleaning shell 8 and the second cleaning shell 7. At this time, the through holes 21 on the first cleaning shell 8 and the second cleaning shell 7 clamp the surface of the wire rope 4. When the crane is working, that is, when the wire rope 4 slides, friction occurs between the surface of the wire rope 4 and the surface of the steel brush 22, so as to erase the rust on the surface of the wire rope 4. Then, as the first cleaning shell 8 and the second cleaning shell 7 move on the sliding rod 9, the rust on the conical surface moves on the conical surface with the vibration generated when the device moves, and then falls into the collection groove 17 through the chute 14. Thus, the cleaning of the rust on the surface of the wire rope 4 is completed.

[0043] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present invention.
