Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of iron and steel metallurgical equipment, in particular to a manual rotating spanner for a coupling of a hot straightening machine of a medium and thick plate production line. Background Art

[0002] On the hot straightening machine of the hot-rolled medium and thick plate furnace coil rolling mill production line, the current mainstream hot straightening machines all use 9-11 straightening rollers to cooperate with each other for straightening. The straightening rollers are usually divided into three groups: entrance, middle and exit for transmission. The main motor divides the power into three parts through the reduction gearbox, which is connected to the distribution gearbox through three couplings. Each coupling transmits the power to the entrance, middle and exit three groups of straightening rollers through the distribution gearbox. Each group of rollers corresponds to 3-6 straightening rollers.

[0003] When the head of the straightening steel plate is bitten in and the tail is thrown out, due to the thick thickness of the head and tail, low temperature, poor head shape, fast biting or throwing speed, and excessive impact force and straightening force at the moment of biting or throwing, the locking pin of the coupling disc overload protection device connected to the straightening roller connecting rod pops out, and the straightening roller loses power instantly, which can easily cause the steel plate to be stuck in the straightening machine. The front and rear steel plates are rear-ended one by one in front of the straightening machine, which has a very large impact on the straightening roller, which can easily cause the straightening roller surface to be injured and produce surface indentations. By reasonably optimizing the straightening process and the signal tracking of the straightening area, and formulating emergency measures, such as: quickly lifting the straightening machine roller gap when abnormal conditions are found, and manually coordinating the roller table with the travel speed of the steel plate, some of the situations that cause the locking pin of the coupling disc overload protection device to pop out are avoided. However, with the diversification and rapid production of steel types, the locking pin of the coupling disc overload protection device pops out from time to time. In addition, when stopping the machine to check the working condition of the straightening roller, it is also necessary to manually twist the coupling to check the equipment condition.

[0004] After the locking pin of the coupling disc overload protection device pops out, the steel plate is driven out of the straightening machine. The operator cuts off the power to the main motor of the straightening machine, and then goes to the site to hold the pin barrel seat on the coupling disc with both hands, and forcefully twists the left and right discs of the coupling to the same line so that the locking pin and the locking hole correspond. Then use a hammer or other tools to knock the locking pin into the corresponding locking hole. In the same way, knock the other locking pins into the corresponding locking holes before resuming production.

[0005] When the operator twists the coupling by hand, it is very difficult to twist the left or right disk of the coupling because the coupling is connected to the main motor, the reduction gear box, the distribution gear box, etc. Once it is twisted and rotated, it is difficult to stop it when the locking pin corresponds to the locking hole. It is time-consuming and laborious to twist or stop the coupling back and forth by hand. If three sets of coupling locking pins are ejected, the processing time is long and the impact on production is relatively large. The operator's on-site handling risk factor increases. For this reason, the utility model proposes a manual rotating wrench for the coupling of a hot straightening machine of a medium and thick plate production line. Utility Model Content

[0006] The utility model aims at the above-mentioned technical problems and overcomes the shortcomings of the prior art, and provides a manual rotating wrench for the coupling of a hot straightening machine of a medium and thick plate production line. The operator can twist the coupling plate by holding the wrench handle and pushing it lightly, so that the locking pin can be quickly and safely aligned with the locking hole, and then the locking pin can be knocked in with the ball head of the wrench, thereby achieving an integrated design of the tool for twisting the coupling plate and knocking in the locking pin.

[0007] The manual rotating wrench of the coupling of the hot straightening machine of the medium and thick plate production line in this scheme includes a wrench body composed of a wrench handle and a clamping part, wherein the clamping part is symmetrically connected to the end of the wrench handle, and the clamping part is arranged in an arc shape to form an open clip shape, wherein a hammer head is connected to the end of the wrench handle away from the clamping part, and the hammer head contacts the locking pin of the coupling when the wrench body is subjected to force. Specifically, the hammer head is used to knock the locking pin into the locking hole after the wrench adjusts the locking pin to align with the locking hole.

[0008] The technical solution further defined in the utility model is:

[0009] Furthermore, a supporting shoulder is connected to the wrench body, which is arranged perpendicular to the wrench body so that when the wrench body operates on one side of the coupling, the supporting shoulder abuts against the other side of the coupling. Specifically, when the wrench body operates on the pin barrel seat of the coupling, the supporting shoulder abuts against the arc outer contour of the coupling disk, thereby playing a force supporting role.

[0010] Furthermore, the supporting shoulder comprises a wrench arc shoulder in the shape of a fan ring, and the curvature is consistent with the arc of the coupling disc contour.

[0011] Furthermore, the wrench handle, the clamping portion, the supporting shoulder and the hammer head are integrally formed.

[0012] Furthermore, the hammer head comprises a spherical wrench ball head.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model adopts a reasonable design to quickly insert the pin barrel seat and the right disc of the coupling by rotating the wrench. The operator can twist the coupling disc by gently pushing the wrench handle, so that the locking pin can be quickly and safely aligned with the locking hole, and then the locking pin can be knocked in with the wrench ball head, so as to achieve an integrated design of the tool for twisting the coupling disc and knocking in the locking pin;

[0015] (2) When the utility model stops the machine to check the straightening roller, the rotating wrench can be used to twist the coupling to check the equipment condition. The use of the rotating wrench tool can greatly reduce the labor intensity of manually twisting the coupling;

[0016] (3) The rotary wrench provided by the utility model has stable operation, simple operation, fast fault handling speed and high safety, which greatly shortens the time for aligning the torsion coupling with the locking pin and the locking hole, reduces the impact on production, and reduces the safety risk when handling faults.

DETAILED DESCRIPTION

[0025] This embodiment provides a manual rotating wrench for a coupling of a hot straightening machine of a medium and thick plate production line, which specifically includes an integrally formed wrench ball head 1-1, a wrench arc shoulder 1-2, a wrench handle 1-3 and a clamping portion 1-4, wherein the wrench handle 1-3 and the clamping portion 1-4 constitute a wrench body 1, such as Figure 1-3 shown.

[0026] Specifically, in the present embodiment, two clamping parts 1-4 are provided and are symmetrically arranged at the end of the wrench handle 1-3. The connection between the two clamping parts 1-4 is arranged in an arc shape to form an open clip shape, which can be clamped on the outer wall of the pin cylinder seat 2-3 of the coupling 2. The end of the wrench handle 1-3 away from the clamping part 1-4 is connected to the hammer head (that is, the spherical wrench ball head 1-1). The wrench ball head 1-1 is used to knock the locking pin 2-5 into the locking hole after the wrench adjusts the locking pin 2-5 to align with the locking hole.

[0027] In this embodiment, a supporting shoulder is also connected to the wrench body 1, and the supporting shoulder is perpendicular to the wrench body 1, so that when the wrench body 1 operates on the coupling pin cylinder seat 2-3, the supporting shoulder 1-2 of the wrench rests on the arc outer contour of the coupling disk to provide force support. The supporting shoulder is specifically a fan-shaped wrench arc shoulder 1-2, and the curvature is consistent with the arc contour of the coupling disk.

[0028] like Figure 4 and Figure 5 As shown in the figure, they are the structural schematic diagrams of the transmission unit assembly and the coupling 2 of the hot straightening machine of the medium and thick plate production line, see Figure 6 and Figure 7 The use process of the manual rotating wrench of the coupling of the hot straightening machine of the medium and thick plate production line in this embodiment is as follows:

[0029] ①, after the locking pin 2-5 of the overload protection device of the coupling 2 pops out, the steel plate is driven out of the straightening machine, and the operator cuts off the power of the main motor of the straightening machine; ②, at the site, use the wrench body 1 to quickly insert the pin barrel seat 2-3 and the right coupling plate 2-2 (such as Figure 6 and Figure 7 ); ③. The operator can twist the right coupling disk 2-2 by holding the wrench handle 1-3 of the wrench body 1 and gently push it, so that the locking pin 2-5 can be aligned with the locking hole quickly and safely; ④. Then align the wrench ball head 1-1 with the locking pin 2-5 and knock the locking pin 2-5 into the locking hole.

[0030] It has been demonstrated that the manual rotary wrench of this embodiment has stable operation, simple operation, fast fault handling speed and high safety, and solves the problems existing in the background technology. The processing time of a single coupling is shortened by about 3 minutes, which greatly shortens the time for handling similar problems, reduces the impact on production, and reduces the safety risk when handling faults.

[0031] In addition to the above embodiments, the present invention may also have other implementations. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
