Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a marking device clamping mechanism. Background Art

[0002] After the road construction is completed, a marker is usually used to spray or paint different colors of paint on the road according to a pre-designed pattern. Different marking styles are used to achieve the functions of road motor vehicle lanes, non-motor vehicle lanes or travel direction indications, and when using a marker, corresponding auxiliary equipment is required.

[0003] After searching

[0004] A hand-held belt tensioning and fixing paint marking device clamping device, with publication number CN208362879U, is installed on various hand-pushed marking vehicles. The fixing frame is a cylindrical structure, which is through-through and has a flange or a fixing ring on any surface and is fixed to the marking vehicle by bolts, and then the spray paint can is clamped by the clamping device arranged inside, so as to achieve the effect of fixing the spray paint can. The belt is a soft belt structure arranged symmetrically and parallel, generally made of rubber material, by fixing two belts, then pulling the two belts to move to the opposite side and clamping the spray paint can, and finally clamping the two belts by the fixing device to keep them in a tensioned state, so as to clamp the spray paint can by the elastic deformation of the belt.

[0005] However, in actual use, because the belt is made of flexible material, the paint spray can will vibrate due to bumps or vibrations of the marking vehicle during movement. Also, because the belt is a soft structure, the paint spray can will not be able to maintain the same frequency of vibration as the marking vehicle, which will easily affect the effect of painting.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-4As shown, a marking device clamping mechanism includes a fixing frame 1, one side of the fixing frame 1 is flat, and the fixing frame 1 arranged in a flat shape does not affect the size of the placed spray paint can, and a rotating column 2 is embedded and rotatably connected at two vertical sides of one side of the fixing frame 1, the top of the rotating column 2 passes through the fixing frame 1 and extends outward, and a plurality of clamping blocks 6 are inserted on the rotating column 2, the part of the rotating column 2 located in the fixing frame 1 is arranged in a rectangular column shape, and the surface is hollowed out, the clamping block 6 is arranged in a U-shape, and a fixing bolt 7 is connected between the clamping block 6 and the hollow part of the rotating column 2, the U-shaped clamping block 6 ensures that it can only slide on the surface of the rotating column 2 and will not rotate relative to the rotating column 2, and the fixing bolt 7 is used to pass through the hollow parts of different heights on the rotating column 2 and The block 6 is threadedly connected, which is convenient for adjusting the number of blocks 6 on the rotating column 2 and the installation height, and the installed block 6 can rotate with the rotation of the rotating column 2. The top edge position of one side of the block 6 is rotatably connected with the electric telescopic rod 14, and the bottom edge position is extended outward and rotatably connected with a rotating arm 9 hinged to the telescopic end of the electric telescopic rod 14 at the middle position of the surface. The swing end of the rotating arm 9 is hinged with an extension arm 8. The rotation of the rotating arm 9 can be achieved by telescoping the electric telescopic rod 14. The rotating connection between the rotating arm 9 and the extension arm 8 can realize that the rotation point of the extension wall 8 and the rotating arm 9 can be moved relative to the block 6, that is, the horizontal distance between the extension arm 8 and the block 6 is adjusted. One side of the block 6 is rotatably connected to the position below the rotating arm 9 The support arm 11 has two sides of a swinging edge extending outward and sleeved on the lower surface of the extension arm 8. After the rotating arm 9 is rotated, the support arm 11 is rotated and the swinging edge of the support arm 11 is used to slide on the bottom surface of the extension arm 8. When the height of the connecting edge between the extension arm 8 and the rotating arm 9 remains unchanged, the installation height of the swinging edge of the extension arm 8 can be adjusted. In the process of adjusting the height, the closer the swinging edge of the extension arm 8 is to the horizontal plane of the bottom edge of the block 6, the swinging edge of the extension arm 8 gradually moves away from the block 6. Conversely, the farther the swinging edge of the extension arm 8 is from the horizontal plane of the bottom edge of the block 6, the swinging edge of the extension arm 8 gradually approaches the block 6. That is, the swinging edge position of the extension arm 8 can be further adjusted. After the adjustment is completed, the support arm 11 is fixed. The angle can realize the fixed position of the extension arm 8, and one side of the swing end of the extension arm 8 is rotatably connected to a rotating block 12, and the two sides of one side of the rotating block 12 are symmetrically and evenly hollowed out, and the rotating block 12 is installed with a clamping block 13 through the hollow part. By adjusting the position of the swinging side of the extension arm 8, the horizontal distance between the rotating block 12 and the clamping block 6 can be adjusted, and the clamping block 6 and the rotating block 12 are driven to rotate by the rotating column 2, and then the two clamping blocks 13 on the rotating block 12 can be used to clamp spray cans of different diameters. Therefore, the position of the support arm 11 is fixed and the position of the rotating arm 9 is fixed, which ensures that the position of the extension arm 8 is fixed. Therefore, when the extension arm forces the rotating block 12 to clamp the spray can, the whole is rigidly clamped, thereby ensuring that the spray can does not produce unnecessary vibration.

[0024] In order to drive the two rotating columns 2 to rotate: the rotating column 2 passes through one end of the fixed frame 1 and is fixedly connected to a worm gear 3, and the top edge of the fixed frame 1 is a dual-axis motor 5 fixedly connected between the two worm gears 3, and the two output shafts of the dual-axis motor 5 extend toward the two worm gears 3 respectively, and are fixedly connected to a worm 4 meshing with the worm gear 3. By driving the two worm gears 4 to rotate by the dual-axis motor 5, the corresponding meshing worm gear 3 can drive the rotating column 2 at the corresponding position to rotate. In addition, in this scheme, one end of the worm gear 4 is rotatably connected to the fixed frame 1.

[0025] In order to ensure the stable position of the extension arm 8: a winding drum 18 is rotatably connected to the top edge of one side of the clamping block 6, and a traction rope 10 is wound on the winding drum 18. One end of the traction rope 10 extends to the swinging edge fixed to the extension arm 8, and the winding drum 18 is used to rotate to release or reel the traction rope 10. When the position of the extension arm 8 is fixed, the set traction rope 10 is used to achieve oblique support for the swinging edge of the extension arm 8 to prevent the extension arm 8 from tilting and bending due to the weight of the spray paint can. A gear 15 is fixedly connected to the end face of the winding drum 18, and a rack 17 meshing with the gear 15 is inserted at the top wall position of the side of the clamping block 6. A gear 15 and a rack 17 meshing with the gear 15 are also installed on the side of the clamping block 6 at the rotation point of the support arm 11. The support arm 11 and the rotating part of the clamping block 6 penetrate the clamping block. The block 6 extends outward and is fixed to the end face of the gear 15 at a similar position. A connecting block 19 is fixedly connected between the two racks 17, and an electric push rod 16 for driving one of the racks 17 to slide is fixedly connected to the side of the block 6. When in use, the corresponding rack 17 can be realized by contracting the electric push rod 16, and the other rack 17 can be simultaneously moved to the gear 15 that is out of the corresponding position under the driving action of the connecting block 19, that is, the gear 15 can rotate freely at this time, so the personnel can freely adjust the release length of the traction rope 10 or the inclination angle of the support arm 11, and after the adjustment is completed, the two racks 17 can be re-engaged with the gear 15 at the corresponding position by extending the electric push rod 16 to prevent the gear 15 from rotating, that is, the position of the winding drum 18 and the support arm 11 is fixed.

[0026] Working principle: according to the height of the spray paint can, the fixing bolt 7 is used to adjust the installation quantity and position of the block 6 on the rotating column 2; then, according to the diameter of the spray paint can, the electric telescopic rod 14 is extended and retracted and the support arm 11 is swung to adjust the horizontal distance and vertical distance between the swing end of the skipping rope extension arm 8 and the block 6; when in use, the fixed frame 1 is fixed on the marking vehicle, and the spray paint can is placed on one side of the fixed frame 1; the two worms 4 are driven to rotate by the dual-axis motor 5, so that the corresponding meshing worm gear 3 can drive the rotating column 2 at the corresponding position to rotate; the two rotating columns 2 are used to rotate in the opposite direction, and the rotating block 12 and the clamping block 13 on the extension arm 8 are used to clamp the surface of the spray paint can.

[0027] The wiring diagram of the dual-axis motor 5, the electric telescopic rod 14 and the electric push rod 16 in the utility model belongs to the present invention.

[0028] It is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the dual-axis motor 5, the electric telescopic rod 14 and the electric push rod 16 are no longer explained in detail.
