Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot material pushing plate mechanism on a trolley walking track. Background Art

[0002] The trolley shot blasting machine is also called the trolley shot blasting cleaning machine. It is used for the surface treatment of large cast iron parts, forgings, welded parts and other metal workpieces. It can remove impurities such as sticky sand, rust, scale, dirt, etc. on the surface and restore the original metallic luster of the workpiece. The shot blasting machine can not only perform surface treatment functions, but also eliminate the internal stress of the workpiece, improve fatigue resistance and increase service life. After treatment, the surface of the metal workpiece has a certain degree of roughness, which is more conducive to the adhesion of the paint film of subsequent spraying and painting. The trolley shot blasting machine consists of a shot blasting machine chamber, a trolley, a screw conveyor, a separator, a steel shot ejector, an electric control box, a dust collector and the like.

[0003] In the prior art, the trolley shot blasting machine usually relies on a reducer plus a sprocket structure to drive the running wheels on the trolley to rotate, so as to adjust the overall position of the trolley shot blasting machine. A special track that cooperates with the running wheels is set in the working area of ​​the trolley shot blasting machine. However, the internal environment of the shot blasting room is complex, and it is inevitable that steel shots will be scattered on the track during work. With the increase of working time, when there are more steel shots accumulated on the track, it is easy to affect the normal operation of the trolley running wheels, causing the running wheels to slip. Even when the steel shots are accumulated on the track, it will cause the running wheels to derail and cause safety accidents. For this reason, we propose a trolley running track shot material pushing plate mechanism to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a trolley walking track shot material pushing plate mechanism, which solves the problems raised in the above-mentioned background technology.

[0006] Preferably, a clamping groove cooperating with the running track is provided on the running wheel, and the depth of the clamping groove is 5-10 mm.

[0007] Preferably, the push plate assembly includes a mounting bracket, a pusher plate, a pushing conical surface, and a mounting inclined surface. The pusher plate is fixedly installed in the middle of the push plate, and the width of the pusher plate is adapted to the traveling wheels and the traveling track.

[0008] Preferably, the overall shape of the mounting bracket is "U"-shaped. Mounting holes are provided on both sides of the mounting bracket, and the mounting bracket is installed on the trolley frame through bolts.

[0009] Preferably, the mounting inclined surface is arranged on one side of the pushing conical surface close to the center of the traveling wheel, and the pushing conical surface is provided on the side away from the center of the traveling wheel.

[0010] Preferably, the bottom of the push plate assembly is 1-2 mm higher than the contact surface between the traveling wheel and the traveling track.

[0011] The utility model provides a shot pushing plate mechanism for a trolley traveling track, which has the following beneficial effects:

[0012] 1. For this shot pushing plate mechanism for a trolley traveling track, by arranging push plate assemblies at both the forward and backward ends of the traveling wheels, when the trolley frame moves, the pusher plate in the push plate assembly can push the steel shots scattered on the surface of the traveling track away, avoiding the influence of steel shots on the rotation of the traveling wheels. At the same time, it can prevent the steel shots from piling up too high and causing the traveling wheels to derail, improving safety. At the same time, a pushing conical surface is arranged at the pushing end of the pusher plate. During the pushing process, the steel shots can be directly pushed away and dropped from the traveling track, realizing the cleaning of the steel shots scattered on the surface of the traveling track.

[0013] 2. For this shot pushing plate mechanism for a trolley traveling track, the height of the push plate assembly is limited, so that the bottom of the push plate assembly is 1-2 mm higher than the contact surface between the traveling wheel and the traveling track, ensuring that the push plate assembly can effectively push the materials while avoiding affecting the movement of the traveling wheels. In addition, the entire push plate assembly is installed on the trolley frame through bolts, and the entire push plate assembly is exposed outside the traveling wheels, facilitating disassembly, installation, and maintenance.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1 , 2 3. The utility model provides a technical solution: a trolley walking track shot material pushing plate mechanism, including a trolley frame 1 and a walking track 6. A shot blasting machine turntable 2 is movably installed on the top of the trolley frame 1. A turntable driving assembly 3 cooperating with the shot blasting machine turntable 2 is arranged inside the trolley frame 1. The shot blasting machine turntable 2 and the turntable driving assembly 3 are currently common existing technologies. The turntable driving assembly 3 can provide power for the rotation of the shot blasting machine turntable 2. The front and rear parts of the left and right sides of the trolley frame 1 are movably installed with walking wheels 4. The trolley frame 1 is mounted on the walking track 6 through the walking wheels 4. The walking wheels 4 are driven by the internal power assembly of the trolley frame 1 to rotate and can be rotated on the walking track. The trolley frame 1 is provided with a push plate assembly 5 located at the front and rear ends below the traveling wheel 4. When the trolley frame 1 moves, the steel shots scattered on the surface of the traveling track 6 are pushed away by the push plate 52 in the push plate assembly 5 to avoid the steel shots from affecting the rotation of the traveling wheel 4 and at the same time avoiding the derailment of the traveling wheel 4 caused by excessive accumulation of steel shots. The two groups of push plate assemblies 5 are mirror-distributed at the front and rear ends of the traveling wheel 4. The trolley frame 1 moves back and forth during operation. Push plate assemblies 5 are arranged at the forward and backward ends of the traveling wheel 4 to ensure that the steel shots on the surface of the traveling track 6 can be cleaned when the trolley frame 1 operates back and forth.

[0022] See also Figure 4 , 5 A snap-in groove cooperating with the walking track 6 is provided on the walking wheel 4, and the depth of the snap-in groove is 5-10 mm. A snap-in groove is provided on the walking wheel 4 so that the walking wheel 4 can be snapped onto the walking track 6 through the snap-in groove, ensuring that the walking wheel 4 and the walking track 6 can be stably matched and preventing the walking wheel 4 from sliding along the walking track 6.

[0023] The push plate assembly 5 includes a mounting bracket 51, a pusher plate 52, a pusher cone surface 53, and a mounting inclined surface 54. The pusher plate 52 is fixedly installed in the middle of the pusher plate 52. The pusher plate 52 can be installed on the mounting bracket 51 by means of bolt connection, welding, etc. to ensure the stability of the pusher plate 52 during operation. The width of the pusher plate 52 is adapted to the traveling wheels 4 and the traveling track 6 to limit the width of the pusher plate 52 and ensure that the pusher plate 52 can comprehensively clean the steel shot scattered on the surface of the traveling track 6 when moving.

[0024] Please refer to Figure 3 、 4 、5. The overall shape of the mounting bracket 51 is in a "U" shape. Mounting holes are provided on both sides of the mounting bracket 51. Bolts are used to fix both ends of the mounting bracket 51 to ensure a firm connection between the mounting bracket 51 and the trolley frame 1, thereby improving the stability of the pusher plate 52 after installation. The mounting bracket 51 is installed on the trolley frame 1 by bolts. The entire push plate assembly 5 is installed on the trolley frame 1 by bolts, and the entire push plate assembly 5 is exposed outside the traveling wheels 4 for easy disassembly and maintenance.

[0025] An installation inclined surface 54 is provided on one side of the pusher cone surface 53 close to the center of the traveling wheel 4. The installation inclined surface 54 cooperates with the traveling wheel 4 to prevent the pusher plate 52 from interfering with the rotation of the traveling wheel 4. A pusher cone surface 53 is provided on the side away from the center of the traveling wheel 4. The pusher cone surface 53 is provided at the pusher end of the pusher plate 52. During the pusher process, the steel shot can be directly pushed away and dropped from the traveling track 6 to clean the steel shot scattered on the surface of the traveling track 6.

[0026] The bottom of the push plate assembly 5 is 1-2 mm higher than the contact surface between the traveling wheel 4 and the traveling track 6 to limit the height of the push plate assembly 5. While ensuring that the push plate assembly 5 can effectively push the material, it avoids affecting the movement of the traveling wheel 4. When the bottom of the push plate assembly 5 directly contacts the traveling track 6, it acts as a brake and will hinder the operation of the traveling wheel 4 and the movement of the trolley frame 1.

[0027] In summary, for this trolley traveling track shot pusher mechanism, during use, the push plate assembly 5 is installed on the trolley frame 1 by bolts and is located at the front and rear ends of the traveling wheels 4. When the trolley frame 1 travels on the traveling track 6, the pusher plate 52 in the push plate assembly 5 pushes away the steel shot scattered on the surface of the traveling track 6. At the same time, a pusher cone surface 53 is provided at the pusher end of the pusher plate 52. During the pusher process, the steel shot can be directly pushed away and dropped from the traveling track 6 to prevent the steel shot from existing between the traveling wheel 4 and the traveling track 6 and ensure the normal operation of the traveling wheel 4. The bottom of the push plate assembly 5 is 1-2 mm higher than the contact surface between the traveling wheel 4 and the traveling track 6 to ensure that the push plate assembly 5 can effectively push the material while avoiding affecting the movement of the traveling wheel 4. That's it.
