Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of surface treatment equipment for metal parts, and in particular to a hoisting polishing machine. Background Technology
[0002] As the core equipment for metal surface treatment, the traditional design of the hanging shot blasting machine usually relies on the coordinated operation of two independent moving mechanisms: lifting and horizontal movement.
[0003] For example, a crane can be used to vertically lift the hanger, while a track or a traveling motor can drive the hanger to move horizontally, thereby removing the hanger from the polishing chamber for workpiece loading, unloading, or cleaning operations. While this dual-mechanism linkage method achieves the basic function, its overall movement efficiency is low due to the complexity of the mechanical structure and the need for synchronization and coordination.
[0004] Furthermore, the crane mentioned above needs to move along with the traveling motor, which will cause the traveling motor to consume more energy. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a hoisting thrower that solves the technical problem of low movement efficiency of the hoisting frame during loading and unloading in existing hoisting throwers.
[0006] A hoisting projectile according to an embodiment of the present invention includes a hoisting projectile body and a hoisting rail device disposed on the top of the hoisting projectile body;
[0007] The hoisting polisher body is provided with a polishing chamber, one side of the polishing chamber is provided with an opening and closing door, the other sides of the polishing chamber are provided with sandblasting devices, and the bottom center of the polishing chamber is provided with a rotating device;
[0008] The hanging rail device includes an inclined rail, a hanger mounted on the inclined rail, and a crane connected to the hanger. The inclined rail extends from the center of the polishing chamber toward the side of the opening and closing door, and the height of the inclined rail gradually decreases from the center of the polishing chamber toward the side of the opening and closing door. The crane is located on the upper side of the highest point of the inclined rail. The bottom of the hanger can be tightly attached to the rotating device.
[0009] The technical principle of this utility model is as follows: After the hanger is suspended on the inclined track, the crane pulls the hanger along the inclined track. As it moves into the polishing chamber, its horizontal level gradually increases until it reaches the center of the polishing chamber, which is the top position of the inclined track. At this time, the bottom of the hanger just contacts the rotating device. Then the opening and closing door is closed, and the sandblasting device is started for polishing. The rotating device rotates, which drives the hanger to rotate, making the polishing more uniform. After polishing is completed, the opening and closing door is opened, and the crane gradually releases the hanger, allowing the hanger to slide out of the polishing chamber along the inclined track, thus completing the unloading.
[0010] Compared with the prior art, this utility model has the following advantages: by using an inclined track in conjunction with a crane to achieve rapid feeding and discharging, it solves the technical problem of low movement efficiency of the existing crane's frame during feeding and discharging, and at the same time reduces energy consumption during feeding and discharging.
[0011] Preferably, the rotating device is located at the center of the bottom of the polishing chamber, whereas traditional hanging polishers place the rotating device on a track. With this application, the rotating device is located at the bottom, so there is no need to move it during loading and unloading, which helps to reduce energy consumption.
[0012] Furthermore, the bottom of the inclined track is provided with a T-shaped groove, a slider is provided in the T-shaped groove, rollers are provided on both sides of the slider, and a connecting part is provided at the bottom of the slider, the connecting part being connected to the hanger.
[0013] Furthermore, each side of the slider has two pulleys along its length, and the highest point of the inclined track has a section of parallel track. The length of the parallel track is equal to the diameter of one pulley, and the joint between the parallel track and the inclined track is on the same vertical line as the hanger and the rotating device.
[0014] Furthermore, the parallel track has a recess, and two pulleys on the side near the parallel track can be inserted into the recess.
[0015] Furthermore, the rotating device includes a rotating motor, the shaft of which abuts against the bottom of the hanger.
[0016] By setting the recess, the hanger can be stably set on the parallel track, while ensuring that the hanger and the rotating shaft of the motor are fully in contact.
[0017] Furthermore, the rotating device includes a rotating motor and a clamping mechanism disposed on the rotating motor;
[0018] The clamping mechanism includes two L-shaped clamping blocks and a pressing ball. The two L-shaped clamping blocks are symmetrically arranged on both sides of the top of the rotating shaft of the rotating motor. The bent part of the L-shaped clamping block is hinged to the rotating shaft. The two L-shaped clamping blocks have a groove at one end close to each other. A pressing rod is movably installed on the two L-shaped clamping blocks in the groove. The pressing ball passes through the pressing rod and is located in the groove. An elastic element is provided between the pressing ball and the rotating shaft. The bottom of the hanger presses on the upper side of the pressing ball.
[0019] By setting up a clamping mechanism, slippage is less likely to occur during transmission between the rotating device and the hanger.
[0020] Furthermore, elongated holes are provided on both sides of the groove, and the pressing rod passes through the elongated holes.
[0021] Furthermore, both the bottom of the pressing ball and the top center of the rotating motor shaft are provided with convex cylinders, and the elastic element is a compression spring, which is locked at the two convex cylinders.
[0022] Furthermore, the crane includes a winding roller that is driven and connected to a drive motor, and a lifting rope is provided on the winding roller, which is connected to the top of the crane frame.
[0023] Furthermore, the crane is located on top of the hoisting polisher body, and the top of the hoisting polisher body has a channel connecting to the polishing chamber, the channel extending from the center of the polishing chamber to the opening and closing door. Attached Figure Description

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0032] Example 1
[0033] like Figure 1 The suspended polishing machine shown includes a machine body 1 and a suspension rail device installed on the top of the machine body 1. The machine body 1 is provided with a polishing chamber 11. One side of the polishing chamber 11 is provided with an opening and closing door 111 for the parts to be processed to enter and exit. The other sides of the polishing chamber 11 are provided with sandblasting devices 12. The bottom of the polishing chamber 11 may be provided with an outlet 112 for waste sand recycling. After filtration and other steps, the waste sand can be returned to the sandblasting device 12 and sprayed out.
[0034] The specific hanging rail device includes an inclined rail 2, a hanger 3 set on the inclined rail 2, and a crane 4 connected to the hanger 3. The inclined rail 2 extends from the center of the polishing chamber 11 toward the opening and closing door 111. The height of the inclined rail 2 gradually decreases from the center of the polishing chamber 11 toward the opening and closing door 111, forming an inclined slope, allowing the hanger 3 to move along it, and simultaneously achieving horizontal and vertical movement.
[0035] like Figure 1-2 As shown, the specific crane 4 includes a drive motor 41 and a winding roller 42 that is connected to the drive motor 41. The winding roller 42 is provided with a lifting rope 43, which is connected to the top of the hanger 3. The specific crane 4 is set on the upper side of the highest point of the inclined track 2, and the crane 4 is set on the top of the crane body 1. The top of the crane body 1 is provided with a channel 113 that connects to the polishing chamber 11. The channel 113 extends from the center of the polishing chamber 11 to the opening and closing door 111, so that the lifting rope 43 can pass through the channel 113 to connect to the hanger 3. No matter where the hanger 3 is in the inclined track 2, the channel 113 will not obstruct the connection of the lifting rope 43 to the hanger 3.
[0036] like Figure 1 , 3As shown, a rotating device 5 is provided at the bottom center of the polishing chamber 11. The rotating device 5 includes a rotating motor. The rotating shaft of the rotating motor abuts against the bottom of the hanger 3, so that the rotating motor can drive the hanger 3 to rotate.
[0037] like Figure 4-5 As shown, the bottom of the inclined track 2 is provided with a T-shaped groove 21, and a slider 22 is provided in the T-shaped groove 21. Rollers 221 are provided on both sides of the slider 22. The slider 22 is restricted in the T-shaped groove 21 by the pulleys. The bottom of the slider 22 is provided with a connecting part 223, which is connected to the hanger 3. The connection between the connecting part 223 and the hanger 3 can be a hook structure. Specifically, a bearing structure 222 is provided between the slider 22 and the connecting part 223 to ensure that the inclined track 2 is not affected when the rotating device 5 drives the hanger 3.
[0038] like Figure 5 As shown, each side of the slider 22 has two pulleys along its length. The highest point of the inclined track 2 has a section of parallel track 23. The length of the parallel track 23 is equal to the diameter of one pulley. The joint between the parallel track 23 and the inclined track 2 is on the same vertical line as the hanger 3 and the rotating device 5, ensuring that the bottom of the hanger 3 can be connected to the rotating device 5. Specifically, the parallel track 23 has a recess 231. The two pulleys on the side closest to the parallel track 23 can be inserted into the recess 231, so that when the hanger 3 reaches the position, it will drop a little height to ensure that it fully contacts the rotating shaft of the rotating motor 51.
[0039] It should be noted that when implementing the above technical solution, care should be taken to prevent the suspension rail from swaying left and right, otherwise the rotating shaft of the rotating motor 51 may not be in contact with the bottom of the suspension rail.
[0040] Example 2
[0041] like Figure 6 As shown, the rotating device 5 includes a rotating motor 51 and a clamping mechanism 52 mounted on the rotating motor 51. The clamping mechanism 52 includes two L-shaped clamping blocks 521 and a pressing ball 522. The two L-shaped clamping blocks 521 are symmetrically arranged on both sides of the top of the rotating shaft of the rotating motor 51. The bent portions of the L-shaped clamping blocks 521 are hinged to the rotating shaft. The two L-shaped clamping blocks 521 have grooves 5211 at one end close to each other, and elongated holes 5212 are provided on both sides of the grooves 5211. Two L-shaped clamping blocks 521 are provided with a pressing rod 5213 at the groove 5211. The pressing rod 5213 passes through the elongated hole 5212. The pressing ball 522 passes through the pressing rod 5213 and is located in the groove 5211. The bottom of the pressing ball 522 and the top center of the rotating shaft of the rotating motor 51 are provided with a convex cylinder 5221. A compression spring 523 is sleeved between the two convex cylinders 5221. The bottom of the hanger 3 presses on the upper side of the pressing ball 522.
[0042] When the hanger 3 moves to the clamping mechanism 52, the bottom of the hanger 3 will contact the pressing ball 522, causing the pressing ball 522 to be pressed down, causing the L-shaped clamping blocks 521 to move closer to each other and rotate, thereby clamping the hanger 3; and because of the recess 231 at the parallel track 23, the L-shaped clamping blocks 521 can firmly clamp the hanger 3. When discharging, because the hanger 3 needs to move out of the recess 231, it will move upward first. At this time, the L-shaped clamping blocks 521 will release the hanger 3, allowing the hanger 3 to discharge the material.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
