Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wire rope traction metering device. Background Technology

[0002] Steel wire ropes are used in the process of using coarse screens in sewage treatment plants. Due to the lifting and lowering movement of the screens, the steel wire ropes will inevitably be worn. In order to ensure safe use, the steel wire ropes need to be replaced when they are worn.

[0003] When replacing the wire rope in a coarse grating, a fixed amount of wire rope needs to be cut from the large wire rope coil. In the past, the wire rope coil was placed on a support, and the operator held the support. Because the wire rope coil was very heavy, it took 2 to 3 people to pull the wire rope to cut it. The length needed to be measured with a ruler each time. The cut wire rope also needed to be manually coiled and pulled to the site for use. The whole process was time-consuming, laborious and extremely inconvenient.

[0004] Therefore, this utility model proposes a wire rope traction and metering device, in which a wire rope coil is installed on a mounting frame and driven by a drive motor to rotate the wire rope coil. At the same time, the wire rope is wound by a winding device, and the length of the wire rope is measured by the number of turns of the wire rope. The process saves manpower and brings convenience to the user. Utility Model Content

[0029] Embodiments of this utility model:

[0030] like Figure 1-7 As shown, in this embodiment, a mounting frame 1 is provided, and a wire rope coil 2 is installed on one side of the mounting frame 1. The wire rope pulled out from the wire rope coil 2 is evenly wound onto the winding device 7 via the guide device 3 and the rope management device 5. The counting sensor 74 cooperates with the winding frame 73 in the winding device 7 to measure the number of rotations of the winding device 7.

[0031] In this embodiment, the wire rope coil 2 is installed in the mounting frame 1 via the second rotating shaft 8. A support plate 81 is fixedly installed below the second rotating shaft 8, and the support plate 81 cooperates with the turntable below the wire rope coil 2 (the wire rope coil 2 is commercially available, with wooden turntables on the top and bottom sides and a through hole in the middle). The second rotating shaft 8 is inserted into the through hole in the wire rope coil 2. The bottom of the second rotating shaft 8 is connected to a tapered bearing 82, and the bearing sleeve (outer ring) of the tapered bearing 82 is fixedly connected to the bottom of the mounting frame. The top of the second rotating shaft 8 is connected to a second bearing 83, which is fixedly connected to the top of the mounting frame 1. The top of the second bearing 83 is connected to a lifting ring 85. A damping device 84 is provided on the second rotating shaft 8, and the damping device 84 includes a rubber ring 841, which is sleeved on the second rotating shaft 8. On the two rotating shafts 8, a sleeve 842 is provided outside the rubber ring 841. The sleeve 842 has two semi-circular tubes, and each sleeve 842 has a connecting part. A second threaded rod 843 is connected through the connecting part. A spring 844 is provided between the end of the second threaded rod 843 and the connecting part. The spring 844 is sleeved on the second threaded rod 843. A connecting frame 845 is provided on the outside of one of the sleeves 842. The connecting frame 845 is L-shaped. One side is fixedly connected to the sleeve 842, and the other side extends upward and is fixedly connected to the second bearing 83. The second bearing 83 is fixed to the mounting frame 1 by bolts. The upper end of the connecting frame 845 cooperates with the fixing bolt of the second bearing 83 and is installed and fixed. The gap between the upper end of the connecting frame 845 and the mounting frame 1 is filled by a connecting sleeve 846.

[0032] After being pulled out, the end of the wire rope is engaged with the guide device 3. The guide device 3 extends downward from the mounting frame 1 with a first connecting piece 31. The first connecting piece 31 is fixedly connected to the mounting frame 1. A second connecting piece 32 is horizontally connected to the first connecting piece 31. The lower part of the second connecting piece 32 is connected to the fixed pulley 33.

[0033] After passing through the guide device 3, the wire rope is engaged with the rope management device 5. The rope management device 5 includes a fifth connecting member 51 extending downward from the mounting frame 1. Sixth connecting members 52 are arranged laterally on the upper and lower sides of the fifth connecting member 51. The rope management frame 53 is hinged to the rope management frame 53 through the two sixth connecting members 52. The rope management frame 53 includes a first connecting rod 531 and a second connecting rod 532.

Two first bearings 72 are spaced apart and each engages with a first rotating shaft 71. It should be noted that both first bearings 72 are fixedly connected to vertical connecting rods in the mounting frame 1. One of the vertical connecting rods connected to a first bearing 72 is not shown in the diagram. Two first winding rods 731 are spaced apart on the first bearings 72, and a second winding rod 732 is positioned between the two first winding rods 731. The first winding rods 731 are perpendicular to the first bearings 72, and the second winding rods 732 are parallel to the second bearings 83.

The winding device 7 is connected to the drive mechanism 6 via the first rotating shaft 71. The drive mechanism 6 includes a drive motor 61, which is fixedly connected to the lower part of the mounting bracket 1. The drive motor 61 is connected to the first sprocket via a bevel gear set 62. A second sprocket is provided on the first rotating shaft 71, and the first sprocket and the second sprocket are connected by a chain drive.

[0035] In one embodiment of this utility model, a clamping device 4 is also provided. The clamping device 4 includes a third connecting member 41 extending downward from the mounting frame 1. The third connecting member 41 is connected to a fourth connecting member 42 extending laterally. A fixing nut 43 is provided on the fourth connecting member 42. The fixing nut 43 is connected to a first threaded rod 44. A hand-held rotating part is provided at the rear end of the first threaded rod 44. A clamping part is provided at the front end of the first threaded rod 44. The clamping part cooperates with the wire rope.

[0036] In one embodiment of this utility model, there are two wire rope rolls 2, two fixed pulleys 33 in the corresponding guide device 3, and two first threaded rods 44 in the clamping device 4, which respectively cooperate with the wire rope in each wire rope roll 2.

[0037] The principle of this utility model is as follows:

[0038] When using this utility model, the wire rope roll 2 is installed first. After one roll of wire rope roll 2 is used up, the connection between the second bearing 83 and the mounting bracket 1 is disconnected by unscrewing the corresponding bolts. At this time, a crane or similar device is used to lift the second bearing 83 through the lifting ring 85 above the second rotating shaft 8. Since the bottom of the second rotating shaft 8 uses a tapered bearing 82, it can be easily lifted without affecting the reinstallation and stable use.

[0039] The second bearing 83 is lowered to the ground, and then the used wire rope coil 2 is removed. The second bearing 83 is then inserted into a new wire rope coil 2 (the wire rope coil 2 is placed horizontally with the through holes on both sides exposed). The support plate 81 fixed on the second bearing 83 (the diameter of the support plate 81 is larger than the diameter of the central through hole of the wire rope coil 2) cooperates with the turntable at the bottom of the wire rope coil 2. The wire rope coil 2 is then lifted again by a crane and placed on the tapered bearing 82. Finally, the second bearing 83 and the "L"-shaped connecting bracket 845 in the damping device 84 are fixed.

[0040] In use, the wire rope on wire rope coil 2 is pulled out and then guided to the winding frame 73 via the fixed pulley 33. The end of the wire rope is then wound and fixed onto the winding frame 73. At this time, the drive motor 61 is started, which drives the winding frame 73 to rotate. During the rotation of the winding frame 73, the counting sensor 74 can count the number of rotations of the winding frame 73. If the counting sensor 74 is a metal sensor (an existing mature sensor, which will not be described in detail), the first winding rod 731 that cooperates with it is made of metal, such as iron. Each time the first winding rod 731 passes the counting sensor 74, it is counted once, thus realizing the counting of the number of rotations of the winding frame 73. During the rotation of the winding frame 73, the wire management device is manually rotated so that the wire rope is in a single layer on the winding frame 73. With uniform distribution and a fixed circumference for one rotation of the winding frame 73, the length of the wound wire rope can be measured. For example, if the length of one rotation on the winding frame 73 is 2m, and it is constructed using eight sub-supports (the sub-supports are composed of the first winding rod 731 and the second winding rod 732), then the length between each two adjacent sub-supports is 25cm. If the counting sensor 74 measures 100 times, the corresponding calculated length of the wire rope is 24.75m. However, in practice, due to the uncertainty of the starting point, there may be some error. The error is at most the length between two sub-supports, i.e., 25cm. In engineering practice, this part can be used as a calculation margin. The loss of at most about 25cm of wire rope (the amount of end fixing is also small and can be ignored) is completely acceptable.

[0041] After the wire rope is cut after measurement, the end of the wire rope may lose traction, which may cause the wire rope on the wire rope roll 2 to loosen. Therefore, in this embodiment of the invention, a clamping device 4 is used to clamp and fix the end of the wire rope. At the same time, a damping device 84 is also used in this invention to provide resistance to the rotation of the wire rope roll 2, so as to prevent the wire rope roll 2 from rotating uncontrollably after the end loses traction, and to ensure the stability of use. After the measured and wound wire rope is cut, it is bundled. After the bundling is completed, it can be directly pulled outward from the winding device 7.
