Description

Technical Field

[0001] The invention relates to the technical field of rollers, and in particular to a roller for quickly dismantling a crossbeam. Background Art

[0002] The roller is an important component used to support the weight of the conveyor belt and materials in the belt conveyor. It can effectively ensure the smooth transportation of materials on the conveyor belt to adapt to the transportation of different types of goods. During the conveying process, the roller bears the weight of the transported object and bears the contact friction between the conveyor belt and the roller surface. In order to ensure the normal operation of the roller in the conveyor and extend the service life of the roller, it is usually necessary to disassemble the roller from the bracket for maintenance or replacement. At present, the roller usually uses a crossbeam as a supporting connection component to connect with the bracket of the conveyor. The connection between the roller crossbeam and the bracket of the conveyor is installed and connected with multiple sets of bolts and nuts. When the roller is disassembled and maintained, all bolts and nuts need to be disassembled in advance before the roller can be separated from the bracket of the conveyor. It can be seen that the installation connection structure of the crossbeam and the conveyor bracket using bolts and nuts is not only inconvenient to disassemble, but also the reinstallation process after the roller maintenance is completed is also complicated and cumbersome. In addition, as detachable small parts, bolts and nuts are very easy to lose during the maintenance process, which seriously affects the efficiency of the disassembly and assembly operation in the roller maintenance.

[0003] To this end, the present invention proposes a roller with a quick-detachable crossbeam to solve the problem that the traditional installation connection method of the roller crossbeam and the conveyor support using multiple sets of bolts and nuts cannot perform quick disassembly and assembly during roller maintenance, resulting in cumbersome, complex and inefficient roller maintenance operations.

[0030] Example 1 It was found during use that when the rollers were disassembled for maintenance, all bolts and nuts had to be removed in advance before the rollers could be separated from the conveyor bracket. This shows that the disassembly and installation operations of the installation connection structure of the beam and the conveyor bracket using bolts and nuts are complicated and cumbersome, which seriously affects the efficiency of the disassembly and assembly operations during roller maintenance.

[0031] like Figure 1 - Fig.12 As shown, the present invention provides a roller for a quick-detachable crossbeam, including a roller bracket 4, the top of which is rotatably connected to a rotating roller 6, the bottom of which is fixedly mounted on a beam frame 3, the upper side of which is mounted on the push-pull rod 5, and a quick-detachable crossbeam support 2, the quick-detachable crossbeam support 2 including a beam plate 201, a limiting card plate 202, a locking plate 203, a locking button 204, a placement plate 205, a locking rod 206, a locking tongue 207, a pushing spring 208, a guide support plate 209 and a guide rod 210, the upper side of the beam plate 201 is fixed with a placement plate 205, the upper side of the beam plate 201 is fixed with a limiting card plate 202, and the lower side of the beam plate 201 is fixed with a pad Plate 1, a placement plate 205 is fixed to the top of the guide support plate 209, a locking plate 203 is fixed to the lower side of the placement plate 205, a beam plate 201 is fixed to the lower side of the locking plate 203, the beam plate 201 is fixed to the bottom end of the guide support plate 209, a push spring 208 is fixed to the front end of the guide support plate 209, a through hole is provided at the center of the guide support plate 209, a locking rod 206 is inserted into the inside of the through hole of the guide support plate 209, a locking button 204 is rotatably connected to the front end of the locking rod 206, a placement plate 205 is fixed to the top of the guide rod 210, the beam plate 201 is fixed to the bottom end of the guide rod 210, and a locking tongue 207 is slidably connected to the outer side of the guide rod 210.

[0032] The locking cam 207 is provided with a plurality of locking plates 207a and 207b, respectively, which are provided with a plurality of locking plates 207b.

[0033] In the disclosed embodiment, the placement plate 205 is an inverted V-shaped structure. The triangular structure formed by welding the V-shaped structure of the placement plate 205 and the beam plate 201 enhances the bearing stability of the placement plate 205 on the installation beam frame 3. Four groups of cylindrical bosses are provided at the central part of the upper inclined surface of the V-shaped structure of the placement plate 205. Every two groups of cylindrical bosses are symmetrically distributed on the left and right. Two groups of through grooves are provided near the front and rear ends of the upper inclined surface of the placement plate 205. The four groups of lock tongues 207 are respectively inserted into the four groups of through grooves of the placement plate 205, so that the lock tongues 207 can be tilted and telescopically moved along the inner wall of the through groove of the placement plate 205 at a 45-degree angle.

[0034] In the disclosed embodiment, the mounting beam 3 is a V-shaped structure, and two groups of left-right symmetrically distributed through groove structures are provided on the upper inclined surface of the V-shaped structure of the mounting beam 3, and the locking tongue 207 is inserted into the through groove of the mounting beam 3. The locking tongue 207 performs horizontal locking and limiting on the mounting beam 3 in the through groove of the mounting beam 3 to prevent the mounting beam 3 from horizontally offsetting on the upper side of the V-shaped structure of the placing plate 205. Two groups of U-shaped grooves are provided at the rear end position of the mounting beam 3, and the convex column of the placing plate 205 is embedded in the U-shaped groove of the mounting beam 3, so that the convex column of the placing plate 205 locks the mounting beam 3 to the upper limit position to prevent the placing plate 205 from bouncing upward and detaching from the placing plate 205 due to the vibration of the rotating roller 6.

[0035] In the disclosed embodiment, there are four groups of limit plates 202, and each group of limit plates 202 is an L-shaped structure. The mounting beam 3 is distributed on the inner side of the L-shaped structure of the two groups of limit plates 202. The upper inclined surface of the V-shaped structure of the mounting beam 3 fits against the inner side of the L-shaped structure of the limit plate 202. The two groups of limit plates 202 provide left and right limit support for the mounting beam 3, preventing the mounting beam 3 from flipping left and right on the upper side of the V-shaped structure of the placement plate 205.

[0036] In the disclosed embodiment, there are two groups of locking rods 206, which are symmetrically distributed front to back. A ring plate protruding outward is provided at the center position of the outer side surface of each group of locking rods 206, and one end of the ring plate is an inclined surface structure. A pushing spring 208 is fixed to the other end of the ring plate of the locking rod 206. During the process of the pushing spring 208 driving the locking rod 206 to move forward along the through hole of the guide support plate 209 through its own elastic force, the inclined surface structure of the ring plate of the locking rod 206 pushes the lower side surfaces of the two groups of locking tongues 207, so that the locking tongues 207 automatically extend outward along the through groove of the placement plate 205 and the guide rod 210 to the through groove of the mounting beam frame 3 for locking.

[0037] In the disclosed embodiment, a through hole extending from front to back is provided at the center position of the lock plate 203, and two groups of concave grooves extending from front to back are provided on the inner side wall of the through hole of the lock plate 203, and the two groups of concave grooves are symmetrically distributed left and right, and the lock button 204 is inserted into the inner side of the through hole of the lock plate 203. When the convex strip structure on the outer side surface of the lock button 204 is vertically staggered with the concave groove of the through hole of the lock plate 203, the rear end of the convex strip of the lock button 204 is attached to the front side surface of the lock plate 203, completing the telescopic sliding locking of the lock button 204 in the through hole of the lock plate 203, preventing the lock button 204 from colliding with the lock button 204 and causing the lock button 204 to push the lock rod 206 to move, thereby preventing the lock tongue 207 from detaching from the through slot of the mounting beam 3.

[0038] In the disclosed embodiment, two groups of convex strips are provided on the outer side surface of the lock button 204, and the convex strips of the lock button 204 are symmetrically distributed up and down. A circular hole groove is provided at the center position of the rear side surface of the lock button 204, and the front end of the lock rod 206 is rotatably connected in the circular hole groove of the lock button 204. A ring plate is provided on the outer side surface of the lock button 204 near the rear end, and the diameter of the ring plate is larger than the diameter of the through hole of the lock plate 203, so as to prevent the push spring 208 from driving the lock rod 206 to pop the lock button 204 out of the through hole of the lock plate 203.

[0039] When installing the rollers in this embodiment, the lower side of the V-shaped structure of the mounting beam 3 is fitted against the upper side of the V-shaped structure of the placement plate 205 and moved from front to back. The rear end of the V-shaped structure of the mounting beam 3 contacts the inclined structure of the locking tongue 207. The mounting beam 3 pushes the locking tongue 207 to slide along the guide rod 210 toward the inner side of the through groove of the placement plate 205. At this time, the locking tongue 207 pushes the inclined surface of the ring plate of the locking rod 206, so that the locking rod 206 moves backward along the through hole of the guide support plate 209. The ring plate of the locking rod 206 squeezes the pushing spring 208, and then continues to push The beam 3 is installed until the beam 3 passes through the two groups of limit card plates 202 of the L-shaped structure and the U-shaped slot of the beam 3 is nested on the outer side of the convex column structure of the placement plate 205. The through slot of the beam 3 is opposite to the through slot of the placement plate 205. The push spring 208 pushes the locking rod 206 forward through the elastic force. The inclined surface of the ring plate of the locking rod 206 pushes the bottom end of the locking tongue 207, so that the two groups of locking tongues 207 extend out of the through slot of the placement plate 205 along the guide rod 210. The locking tongue 207 is inserted into the through slot of the beam 3 for horizontal limit locking. If the roller needs to be maintained or disassembled, the lock button 204 is manually turned so that the two sets of convex strips of the lock button 204 are opposite to the concave grooves on the inner wall of the through hole of the lock plate 203, and then the lock button 204 is pressed backward. The lock button 204 drives the lock rod 206 to move backward to overcome the elastic force of the push spring 208. The inclined surface of the ring plate of the lock rod 206 is separated from the bottom end of the lock tongue 207. The lock tongue 207 slides into the through groove of the placement plate 205 along the guide rod 210 by gravity, and the lock tongue 207 is separated from the through groove structure of the mounting beam frame 3. Then the lock plate 206 is manually pulled out. Push-pull rod 5, push-pull rod 5 drives installation beam 3 to be pulled out from back to front along the upper side of the V-shaped structure of placement plate 205. When the U-shaped slot of installation beam 3 is completely separated from the convex column structure of placement plate 205 and the through slot of installation beam 3 is separated from the through slot structure of placement plate 205, release locking button 204 and continue to pull installation beam 3 forward until installation beam 3 is completely separated from the two sets of limiting clamping plates 202 of the L-shaped structure, so that installation beam 3 drives the rotating roller 6 connected to the top of rotating roller bracket 4 to separate from the quick-release crossbeam support 2, and the roller disassembly work is completed.
