Description

Technical Field

[0001] The utility model relates to the technical field of steel bar straightening, in particular to a steel bar straightening machine protection device. Background Art

[0002] The rebar straightening machine is a rebar processing equipment, which is mainly used to process the rebar into a certain length with the same diameter so that it can be used in subsequent processes. The rebar straightening machine uses a high-speed rotating shaft to transfer the rebar to the pressure roller area. The rotation and compression of the pressure roller make the diameter of the rebar more uniform, and then the rebar is cut into a certain length by a cutter. During the straightening process, the round rebar that has not entered the rebar straightening machine will swing left and right, which can easily cause injury accidents. Therefore, a rebar straightening machine protection device is needed to protect the staff.

[0003] At present, the existing device (such as patent number: CN209773315U) comprises a trumpet-shaped protective cover and a bracket for supporting the protective cover, wherein the protective cover comprises an upper cover and a lower cover, that is, the upper cover is covered on the lower cover to form a small diameter of the protective cover, especially the diameter of the discharge port of the protective cover is small, and then when the group of connecting holes is connected with a group of through holes near the upper end of the second connecting plate, the diameter of the protective cover is large, especially the diameter of the discharge port of the protective cover is large, so that the size of the protective cover can be adjusted according to the diameter of the steel bar or the current swing degree of the steel bar, thereby adjusting the swing degree of the steel bar. The steel bar straightening machine protection device can limit the swing amplitude of the steel bar within a certain range according to external factors such as the rotation speed of the steel bar straightening machine, thereby reducing the probability of safety accidents and environmental pollution caused by the swing of the steel bar.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the device is in use, it is often necessary to move it according to the usage conditions on site, but there is no mechanism for auxiliary movement on the device. Therefore, whenever the device needs to be moved, multiple workers are required to lift and move the device, which is inconvenient. Utility Model Content

At the same time, when the device is not in use, the universal wheel can be stored in the slide groove by rotating the handle in the opposite direction to avoid the universal wheel being subjected to force for a long time, resulting in a reduction in the service life of the universal wheel. At the same time, when the steel bar is straightened, the entire base can be in contact with the ground to reduce shaking. When the handle is turned and the synchronous belt is used to drive the gear and the tooth groove group to mesh, the cylinder will synchronously drive the fixed block to slide in the column groove, the slide groove and the limit groove respectively, providing limit and support, and increasing stability.

[0034] Example

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of the inconvenience of moving the existing device, and the overall idea is as follows:

[0036] In view of the problems existing in the prior art, the utility model provides a steel bar straightening machine protection device, including a steel bar straightening machine protection device body 11, a base 12 is fixedly installed at the lower end of the steel bar straightening machine protection device body 11, a storage groove 13 is opened inside the base 12, and slide grooves 14 are symmetrically opened inside the base 12, each slide groove 14 is located below the storage groove 13, and each slide groove 14 has a symmetrical limit groove 15 on its side wall, and each slide groove 14 has a column groove 16 on its inner wall, and each column groove 16 is communicated with the storage groove 13;

[0037] A movable lifting mechanism is rotatably mounted on the side wall of the base 12;

[0038] The mobile lifting mechanism includes a handle 17, a ratchet self-locking device 18 is arranged on the side wall of the base 12 and the circumferential surface of the handle 17, the base 12 and the ratchet self-locking device 18 are rotatably installed, the handle 17 and the ratchet self-locking device 18 are fixedly installed, and a rotating rod 19 is symmetrically installed in the storage groove 13 for rotation. The mobile lifting mechanism also includes a gear 21, a synchronous belt 22, a cylinder 23, a tooth groove group 24, a fixed block 25 and a universal wheel 26. By rotating the handle 17 and using the synchronous belt 22 to make the two rotating rods 19 drive the gear 21 and the tooth groove group 24 to mesh, the cylinder 23 can drive the fixed block 25 and the universal wheel 26. The universal wheel 26 slides downward and is exposed under the base 12, so that the staff can move the steel bar straightening machine protection device body 11 conveniently, and the ratchet self-locking device 18 can be used for effective self-locking to avoid the universal wheel 26 from resetting when the steel bar straightening machine protection device body 11 is moved. At the same time, when the device is not in use, the universal wheel 26 can be stored in the slide groove 14 by rotating the handle 17 in the opposite direction to avoid the universal wheel 26 being subjected to force for a long time and resulting in a reduction in the service life of the universal wheel 26. At the same time, when the steel bar is straightened, the entire base 12 can be made to contact with the ground to reduce shaking.

[0039] The handle 17 is fixedly installed on the rotating rod 19, each group of gears 21 is fixedly installed on the circumferential surface of the rotating rod 19, the synchronous belt 22 is rotatably installed between the rotating rods 19, each cylinder 23 is slidably installed inside the column groove 16, each tooth groove group 24 is opened on the circumferential surface of the cylinder 23, each tooth groove group 24 is adapted to the gear 21, each fixed block 25 is slidably installed between the limiting grooves 15, each fixed block 25 is slidably installed with the slide groove 14, each fixed block 25 is fixedly installed with the cylinder 23, and each universal wheel 26 is rotatably installed under the fixed block 25. When the handle 17 is rotated and the synchronous belt 22 is used to make the two rotating rods 19 drive the gears 21 and the tooth groove group 24 to engage, the cylinder 23 will synchronously drive the fixed block 25 to slide in the column groove 16, the slide groove 14 and the limiting groove 15 respectively, providing limitation and support, and increasing stability.

[0040] Working principle:

[0041] In the first step, when it is necessary to move the main body 11 of the steel bar straightening machine protection device, the handle 17 on the base 12 can be rotated first to drive the rotating rod 19 to rotate. At this time, the rotating rod 19 fixedly installed with the handle 17 will drive the two rotating rods 19 to rotate synchronously through the synchronous belt 22, and engage with the tooth groove group 24 in the storage groove 13. At this time, each cylinder 23 will slide downward in the column groove 16, and drive the fixed block 25 and the universal wheel 26 to slide downward in the slide groove 14 and the limit groove 15.

[0042] The second step is to stop rotating the handle 17 until the universal wheel 26 is located under the base 12, and then the gear 21 and the ratchet self-locking device 18 on the handle 17 (the ratchet self-locking device 18 is composed of a ratchet and a clamping plate, and the clamping plate will clamp the ratchet for self-locking according to the rotation direction of the ratchet) will self-lock, and then the main body 11 of the steel bar straightening machine protection device can be moved.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
