Description

Technical Field

[0001] The utility model relates to the technical field of fixing and locking devices for European-style hoist columns, and specifically relates to a fixing and locking device for European-style hoist columns. Background Technique

[0002] For the trolley of a European-style hoist, its trolley frame is symmetrically arranged on both sides of the track, and the two trolley frames are connected by a connecting rod. However, during long-term operation and vibration, the trolley frame may generate a small amount of displacement on the connecting rod, resulting in a shortening or increase in the distance between the trolley frames. When the distance between the trolley frames is shortened, the trolley wheels will be in close contact with the track, which is likely to cause jamming during the operation of the trolley; when the distance between the trolley frames increases, the trolley will run unstably on the track, which is likely to cause the trolley to shake during operation.

[0003] A fixing and locking device for European-style hoist columns disclosed in the Chinese Utility Model Patent Application Publication No. CN212893529U, although it solves the problem of the trolley shaking, still has the following disadvantages: First, the above-mentioned fixing and locking device for European-style hoist columns uses bolts for fastening, and this fastening method is relatively cumbersome when disassembling or fastening, resulting in more time consumption when disassembling the European-style hoist; Second, the above-mentioned fixing and locking device for European-style hoist columns uses bolts to press against the connecting rod so that the locking device will not shift, and this method will damage both the bolts and the connecting rod, resulting in scratches and deformation on the outer end of the connecting rod, and causing wear of the bolts.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Embodiment 1:

[0026] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a fixing and locking device for an European-style hoist column, including a connecting rod 1. The connecting rod 1 is cylindrical. The outer end of the connecting rod 1 is slidably connected with a column 2. The column 2 is located on the left half side of the connecting rod 1. A lower fixing plate 3 and an upper fixing plate 4 are provided on the left side of the column 2. Both the front and rear sides of the lower fixing plate 3 are fixedly connected with a first connecting plate 5. The first connecting plate 5 is square. The front, rear, outer and inner side walls of the two first connecting plates 5 are fixedly connected with a second connecting plate 6. The first connecting plate 5 and the second connecting plate 6 are distributed in an L shape. The inner side wall of the second connecting plate 6 is fixedly connected with a fixing rod 7. The inner side wall of the fixing rod 7 is slidably connected with a sliding rod 8. A spring 9 is provided at the outer end of the fixing rod 7. The spring 9 is located between the second connecting plate 6 and the sliding rod 8 and is fixedly connected with the second connecting plate 6 and the sliding rod 8 respectively. Both the lower fixing plate 3 and the upper fixing plate 4 are semi-circular rings. The inner bottom wall of the lower fixing plate 3 and the inner top wall of the upper fixing plate 4 are both in contact with the connecting rod 1. The major diameters of the lower fixing plate 3 and the upper fixing plate 4 are the same, and the minor diameters are both the same as that of the connecting rod 1. A clamping groove is opened at the top of the lower fixing plate 3. The clamping groove is arc-shaped. The bottom of the upper fixing plate 4 is fixedly connected with a second connecting block. The size, quantity and shape of the second connecting block are the same as those of the clamping groove. Through holes 11 penetrate through the front, back, front and back of the clamping groove and the second connecting block. The through holes 11 are circular. The through holes 11 are located between the lower fixing plate 3 and the upper fixing plate 4. The size and shape of the sliding rod 8 are the same as those of the through holes 11. The sliding rod 8 is slidably connected with the through holes 11. The left sides of the front and rear two sliding rods 8 are both inclined from the outside left to the inside right. The sliding rod 8 is in contact with the inner wall of the through holes 11. The outer ends of the tops of the sliding rods 8 are both fixedly connected with a first connecting block 10.

[0027] In use, since the existing European-style hoist column fixing and locking device uses bolts for fastening, this fastening method is rather cumbersome when disassembling or fastening, resulting in a relatively long time consumption when disassembling the European-style hoist. Therefore, there is a European-style hoist column fixing and locking device. When fixing the column 2, first place the lower fixing plate 3 on the left side of the column 2 and at the bottom of the connecting rod 1, so that the right side wall of the lower fixing plate 3 is in contact with the left side wall of the column 2, and the inner bottom wall of the lower fixing plate 3 is in contact with the outer end of the connecting rod 1. Subsequently, first place the upper fixing plate 4 in contact with the top of the connecting rod 1 and on the left side of the lower fixing plate 3, and then push the upper fixing plate 4 to the right so that the right side wall of the upper fixing plate 4 is in contact with the left side wall of the column 2. When the right side wall of the upper fixing plate 4 moves to the left side of the lower fixing plate 3, due to the left sides of the front and rear two sliding rods 8 being arranged in an inclined shape with the outer side to the left and the inner side to the right, the right side wall of the upper fixing plate 4 can squeeze the sliding rods 8 to the right, so that the two sliding rods 8 move towards the outer ends on the front and rear sides, squeezing the spring 9. When the upper fixing plate 4 completely enters the lower fixing plate 3, the through hole 11 at the bottom of the upper fixing plate 4 is aligned with the through hole 11 at the top of the lower fixing plate 3. At this time, the spring 9 rebounds to drive the sliding rods 8 to move inside the through hole 11, thereby blocking the upper fixing plate 4, making the upper fixing plate 4 unable to move, and clamping the upper fixing plate 4 and the lower fixing plate 3.

[0028] Embodiment 2:

[0029] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a fixing and locking device for an European-style hoist column. A groove 12 is provided at the left top of the upper fixing plate 4. The left top of the groove 12 is arc-shaped. A hanging plate 13 is fixedly connected to the left side of the column 2. The hanging plate 13 is located directly above the upper fixing plate 4. A third chute 22 is provided on the left side wall of the hanging plate 13. The third chute 22 penetrates through the hanging plate 13. A clamping block 14 is slidably connected to the inner wall of the third chute 22. The material of the clamping block 14 is rubber-like. The bottom of the clamping block 14 is arc-shaped. The bottom of the clamping block 14 is in close contact with the top of the upper fixing plate 4. A first through groove 15 penetrates through the center of the bottom of the lower fixing plate 3. The first through groove 15 is square. A fixing block 16 is fixedly connected to the bottom of the lower fixing plate 3. The fixing block 16 is square. The fixing block 16 is located directly below the first through groove 15. A second through groove 17 penetrates through the left side wall of the fixing block 16. A top block 18 is slidably connected to the inner wall of the first through groove 15. The lower half of the top block 18 is located inside the second through groove 17. The right bottom of the top block 18 is inclined with the left side lower and the right side higher. A first chute 19 and a second chute are penetrated through the left side wall of the column 2. The first chute 19 is located above the second chute. The size and shape of the first chute 19 are the same as those of the second through groove 17. The first chute 19 is located on the right side of the second through groove 17. A second clamping rod 21 is slidably connected to the inner wall of the first chute 19. The left top of the second clamping rod 21 is inclined with the left side lower and the right side higher. A first clamping rod 20 is fixedly connected to the right bottom of the second clamping rod 21. The first clamping rod 20 is L-shaped. The left end of the first clamping rod 20 is slidably connected to the inner wall of the second chute.

[0030] During use, in the existing fixing and locking device for an European-style hoist column, a bolt is used to tightly press the connecting rod 1 so that the locking device will not shift. However, this method causes damage to both the bolt and the connecting rod 1, resulting in scratches, deformation, etc. on the outer end of the connecting rod 1, and causing wear to the bolt. Therefore, there is a fixing and locking device for an European-style hoist column. After the upper fixing plate 4 and the lower fixing plate 3 are clamped, the clamping block 14 is slid from left to right in the third chute 22, so that the clamping block 14 moves above the upper fixing plate 4 to press against the upper fixing plate 4. Through the setting of the rubber material of the clamping block 14 and the groove 12, the clamping block 14 can be more conveniently moved to the top of the upper fixing plate 4. At this time, the first clamping rod 20 is pulled to move from right to left, so that the second clamping rod 21 enters the first chute 19 and moves towards the second through groove 17. Through the setting that the left top of the second clamping rod 21 is inclined with the left side lower and the right side higher and the right bottom of the top block 18 is inclined with the left side lower and the right side higher, the second clamping rod 21 can squeeze the top block 18 after entering the second through groove 17, so that the top block 18 moves upward to squeeze the bottom of the connecting rod 1, thereby making the lower fixing plate 3 and the upper fixing plate 4 not loose through pressurization. And through the setting that the materials of the top block 18 and the hanging plate 13 are both rubber, scratches or damage to the connecting rod 1 and the upper fixing plate 4 can be avoided.

[0031] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
