Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of nut locking parts, and particularly relates to a device for assisting nut locking. BACKGROUND
[0002] At present, the import is generally locked in the form of a nut, so when the import is online for a long time, the nut will loosen due to long-time walking vibration, leading to axial movement of the guide roller, and even causing the nut to fall off, thus damaging the guide roller or causing a steel running accident. INVENTION CONTENTS
[0003] The utility model discloses a device for assisting nut locking, which can effectively prevent the nut from rotating, reduce the number of failures caused by nut loosening, realize nut locking, avoid axial movement of the guide roller, and minimize the occurrence of a steel running accident.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A device for assisting nut locking includes a fixed block cooperating with a roller end nut, a locking hole is arranged in the middle of the fixed block, the roller end nut is clamped into the locking hole and the two form a clearance fit, left and right positioning holes are further arranged on both sides of the locking hole, a left positioning bolt cooperating with the left positioning hole is connected to the left positioning hole, a right positioning bolt cooperating with the right positioning hole is connected to the right positioning hole, and the fixed block is fixed through the left and right positioning bolts, thereby limiting the rotation of the roller end nut through the locking hole of the fixed block and playing a locking role.
[0006] Further, the inner surface of the locking hole is provided with an anti-skid layer to increase the friction between the hole and the nut and improve the clamping effect.
[0007] Further, the fixed block is a cuboid structure with a length of 4 cm, a width of 3 cm and a height of 0.3 cm, the inner diameters of the left and right positioning holes are 0.5 cm, and the left and right positioning bolts are both internal hexagonal bolts.
[0008] Further, the centers of the left and right positioning holes and the locking hole are located on the same straight line.
[0009] Further, the left and right positioning holes are symmetrically arranged left and right of the locking hole as the center.
[0010] The utility model discloses a technical scheme, through the screw cap is inserted into locking hole, the screw cap exists the rotation tendency, and the rotation of screw cap is prevented by the force, and the positioning of the positioning bolt guarantees that the fixed plate is fixed, thereby reaches the effect of screw cap locking, effectively avoid the problem of screw cap loosening caused by walking steel vibration, reduce the import trouble frequency. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 It is the device structure schematic diagram for assisting screw cap locking of the utility model,
[0012] Figure 2 It is the fixed block structure schematic diagram of the utility model. DETAILED DESCRIPTION
[0013] EMBODIMENT
[0014] In order to make the utility model more clearly, the device for assisting screw cap locking of the utility model is further explained below in conjunction with the drawings, and the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0015] Referring to Figure 2 A device for assisting screw cap locking, including a fixed block 1 with the cooperation of the roller end screw cap, characterized in that:
[0016] The fixed block 1 is a cuboid structure with 4cm length, 3cm width and 0.3cm height, and the middle part is provided with locking hole 2, and the roller end screw cap is inserted into locking hole 2 and forms clearance fit, and the inner surface of locking hole 2 is provided with anti-skid layer 2a, to increase the friction between hole and screw cap, and improve the effect of clamping;
[0017] The two sides of locking hole 2 are further provided with left positioning hole 3 and right positioning hole 4 respectively, and the inner diameter of left positioning hole 3 and right positioning hole 4 is 0.5cm, and the two are symmetrically arranged with locking hole 2 as center;
[0018] Referring to Figure 1 And Figure 2 The left positioning hole 3 is connected with the left positioning bolt 5 matched therewith, and the right positioning hole 4 is connected with the right positioning bolt 6 matched therewith, and the left and right positioning bolts are all internal hexagonal bolts, and the fixed block 1 is fixed through the left and right positioning bolts, so as to limit the rotation of roller end screw cap through the locking hole of fixed block, and play the role of locking.
[0019] When using, the middle locking hole 2 is in clearance fit with the roller end screw cap, and the positioning holes on both sides position the whole device, the locking hole 2 is sleeved on the roller end screw nut that has been locked, and then the positioning holes on both sides are matched with the positioning bolts, so that the roller end screw cap cannot rotate, thereby achieving the purpose of preventing loosening.
[0020] The fixed plate can be made of waste steel or residual pieces, has very low cost, has good fastening effect, is suitable for locking various nuts, and can freely change the shape and size of the locking device according to the size and space size of the roller end nut, so that the locking purpose is achieved.
[0021] After the device is used, the failure time caused by nut loosening or falling can be reduced by 6 hours per year, and the annual output is increased by 810 tons according to the hourly output of 135 tons. According to the benefit of 300 yuan per ton of steel, the total annual profit is 300*810=243000 yuan.
[0022] In addition to the above embodiments, the utility model can also have other implementation manners. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the utility model.
