Description

Technical Field

[0001] This utility model relates to the field of guide bracket technology, specifically a guide bracket that is easy to assemble and disassemble. Background Technology

[0002] In steel section rolling, guide devices are installed before and after the roll passes to ensure the workpiece enters and exits the passes accurately and stably in a predetermined direction and state. Guide devices are also called induction devices. Regardless of the cross-sectional shape of the steel or billet being rolled, guide devices are required at the inlet and outlet of all roll passes; in other words, guide devices are an indispensable component of steel rolling production.

[0003] The installation of such guide devices and guides in the existing technology is quite troublesome, requiring bolts to be tightened for fixation, and there is no corresponding quick-release structure. As a result, when the guide device needs to be replaced for different new materials, the entire operation and replacement process is quite troublesome. Therefore, an improved guide bracket that is easy to install and remove is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a guide bracket that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide bracket that is easy to assemble and disassemble, comprising a fixed bracket, a guide device being provided at the upper end of the fixed bracket, guide rollers being movably arranged on both sides of the guide device via rotating shafts, and a quick-release mechanism for quickly fixing the guide device being provided between the guide device and the fixed bracket, the quick-release mechanism comprising a limiting slide rail, a limiting slider, an extension plate, a limiting hole, a fixing block, and a pin, the limiting slide rails being fixedly provided on both sides of the upper end of the fixed bracket, the limiting sliders being fixedly provided on both sides of the lower end of the guide device, an extension plate being fixedly provided on one side of the surface of the limiting slide rail, a limiting hole being provided in the middle of the surface of the extension plate, a fixing block being fixedly provided on the surface of the guide device, and a pin being movably inserted inside the fixing block.

[0006] Preferably, the lower end of the pin has a notch, and a limit rod is movably arranged inside the notch via a rotating shaft.

[0007] Preferably, a pull block is fixedly provided at the upper end of the pin, which can be used to easily pull the pin upward.

[0008] Preferably, the outer surface of the lower end of the pin is chamfered, which makes it easier to insert the pin into the limiting hole.

[0009] Preferably, a spring is sleeved on the outer surface of the pin between the fixing block and the pulling block. The lower end of the spring is fixedly connected to the fixing block, and the upper end of the spring is fixedly connected to the pulling block. The spring can automatically push the pin to move upward.

[0010] Preferably, mounting holes are provided at the four corners of the upper surface of the fixed bracket, which can be used to easily fix the device as a whole at the target position.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model restricts the forward and backward and up and down movement of the guide device by using a limiting slide rail and a limiting slider. A pin is inserted into the limiting hole to restrict the left and right movement of the guide device. This fixing method makes it easy to disassemble and install the guide device, so that staff can easily replace different guide devices for use.

[0013] When disassembling the guide device, this invention does not allow you to simply pull the pin upwards. This prevents accidental operation. Instead, you must first press the pin downwards to create sufficient distance between the limiting rod and the fixing block. Then, rotate the limiting rod to make it vertical. After that, you can easily pull the pin out of the limiting hole. Then, you can slide the guide device left and right to allow the limiting slider to slide out of the limiting groove, thus completing the disassembly of the guide device. This prevents accidental operation and ensures that the guide device is not easily detached without deliberate disassembly. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a guide bracket that is easy to assemble and disassemble, including a fixed bracket 1. A guide device 2 is provided at the upper end of the fixed bracket 1. Guide rollers are movably arranged on both sides of the guide device 2 through a rotating shaft. A quick-release mechanism for quickly fixing the guide device 2 is provided between the guide device 2 and the fixed bracket 1. The quick-release mechanism includes a limiting slide rail 3, a limiting slider 4, an extension plate 5, a limiting hole 6, a fixing block 7, and a pin 8. The limiting slide rail 3 is fixedly provided on both sides of the upper end of the fixed bracket 1. The limiting slider 4 is fixedly provided on both sides of the lower end of the guide device 2. An extension plate 5 is fixedly provided on one side of the surface of the limiting slide rail 3. A limiting hole 6 is opened in the middle of the surface of the extension plate 5. A fixing block 7 is fixedly provided on the surface of the guide device 2. A pin 8 is movably inserted inside the fixing block 7.

[0021] The lower end of the pin 8 has a notch 9, and a limiting rod 10 is movably installed inside the notch 9 via a rotating shaft. When the pin 8 of this device is inserted into the limiting hole 6, the limiting rod 10 should be vertical to allow the pin 8 to be inserted into the limiting hole 6. After the pin 8 of this device is inserted into the limiting hole 6, the limiting rod 10 is rotated so that the limiting rod 10 rotates horizontally. Then the pin 8 is released, and under the action of the spring 12, the pin 8 and the limiting rod 10 can be pushed upward, so that the limiting rod 10 can be tightly attached to the surface of the fixing block 7. This prevents the pin 8 from detaching from the limiting hole 6. At this time, the guide device 2 is limited by the pin 8 and cannot move left or right to slide out of the limiting slide rail 3, thus fixing the guide device 2. When it is necessary to disassemble the guide device 2... Simply pulling the pin 8 upwards will not work; this prevents accidental operation. First, press the pin 8 downwards to create sufficient distance between the limiting rod 10 and the fixing block 7. Then, rotate the limiting rod 10 to make it vertical. Afterwards, the pin 8 can be easily pulled out of the limiting hole 6. Then, the guide device 2 can be slid left and right, causing the limiting slider 4 to slide out of the limiting groove, thus completing the disassembly of the guide device 2. In this way, the device restricts the forward and backward, and up and down movement of the guide device 2 through the limiting slide rail 3 and the limiting slider 4. The pin 8 is inserted into the limiting hole 6 to restrict the left and right movement of the guide device 2. This fixing method facilitates the disassembly and installation of the guide device 2, allowing staff to easily replace different guide devices 2 for use.

[0022] A pull block 11 is fixedly provided at the upper end of the pin 8, and the pin 8 can be easily pulled upward by the pull block 11.

[0023] The lower outer surface of the pin 8 is chamfered, which makes it easier to insert the pin 8 into the limiting hole 6.

[0024] A spring 12 is fitted on the outer surface of the pin 8 between the fixing block 7 and the pull block 11. The lower end of the spring 12 is fixedly connected to the fixing block 7, and the upper end of the spring 12 is fixedly connected to the pull block 11. The spring 12 can automatically push the pin 8 to move upward.

[0025] Mounting holes 13 are provided at the four corners of the upper surface of the fixed bracket 1, and the device can be easily fixed and installed at the target position through the mounting holes 13.

[0026] Working principle: Before fixing the guide device 2 using this device, the pin 8 is in its uppermost position under the action of the spring 12, preferably misaligned with the fixing block 7. Then, the limiting slider 4 is aligned with the limiting groove and slid in. Next, the pin 8 is inserted into the limiting hole 6. When the pin 8 is inserted into the limiting hole 6, the limiting rod 10 should be vertical to allow the pin 8 to be inserted into the limiting hole 6. After the pin 8 is inserted into the limiting hole 6, the limiting rod 10 is rotated horizontally. Then, the pin 8 is released. Under the action of the spring 12, the pin 8 and the limiting rod 10 are pushed upwards, allowing the limiting rod 10 to press tightly against the surface of the fixing block 7. This prevents the pin 8 from detaching from the limiting hole 6. At this time, the guide device 2 is limited by the pin 8 and cannot move left or right to slide out of the limiting slide rail 3. It can serve to fix the guide device 2. However, when it is necessary to disassemble the guide device 2, it is not possible to simply pull the pin 8 upwards. This serves to prevent accidental operation. Only by first pressing the pin 8 downwards to make sufficient distance between the limiting rod 10 and the fixing block 7, and then rotating the limiting rod 10 to make the limiting rod 10 vertical, can the pin 8 be easily pulled out from the limiting hole 6. Then, the guide device 2 can be slid left and right to make the limiting slider 4 slide out from the limiting groove, thus completing the disassembly of the guide device 2. In this way, the device restricts the forward and backward and up and down movement of the guide device 2 through the limiting slide rail 3 and the limiting slider 4. The pin 8 is inserted into the limiting hole 6 to restrict the left and right movement of the guide device 2. This fixing method makes it convenient to disassemble and install the guide device 2, so that the staff can easily replace different guide devices 2 for use.
