Description

Technical Field

[0001] This utility model belongs to the field of anti-fall guide rail processing technology, specifically relating to an anti-fall guide rail cut support device. Background Technology

[0002] Fall arrestor rails are used to securely install fall arrestor blocks onto iron towers. These blocks are then connected to the operator via safety belts or installation ropes, providing safety protection. To improve the alignment accuracy of the fall arrestor rails during installation, a notch is typically cut at one end of the rail, and a corresponding protrusion is cut at the other end. During installation, the protrusion slides into the notch to position the two adjacent rails. When machining the notch, one end of the rail needs to be placed on a punch press to create the notch. A support device is usually installed on one side of the punch press to hold the rail. However, most of these support devices have a flat top surface, making it inconvenient to remove the rail after the notch is cut, resulting in difficulties in handling the rail after the notch is cut. Utility Model Content

[0003] This utility model provides a fall-prevention guide rail cut support device, which aims to solve the problem in the prior art that fall-prevention guide rails are not easy to remove from the support device after the cut is completed.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a fall-prevention guide rail cutout support device, comprising:

[0005] Support frame;

[0006] A placement platform is installed on the support frame. The placement platform includes a support section and a positioning section along its length. The support section is provided with a downwardly recessed cavity, and the positioning section is used to position the guide rail.

[0007] The support roller is rotatably disposed inside the cavity to support the guide rail;

[0008] A lever is hinged in the middle to the positioning section, and one end of the lever can rotate out of the top surface of the positioning section to lift the guide rail.

[0009] The pusher has its fixed end hinged to the positioning section and its driving end hinged to the other end of the dial plate, which is used to drive the dial plate to rotate.

[0010] In one possible implementation, an elastic element for pulling the dial plate downward is further provided between the placement platform and the dial plate.

[0011] In one possible implementation, the dial plate may have a horizontal arm fixedly installed at one end of the top of the positioning section to increase the contact area with the guide rail, the length direction of the horizontal arm being set along the width direction of the positioning section.

[0012] In one possible implementation, the cross arm is a cylindrical structure, and the cross arm is rotatably mounted on the dial plate.

[0013] In one possible implementation, a baffle is mounted on the top of the positioning segment to position the guide rail on the positioning segment along the width direction of the positioning segment.

[0014] In one possible implementation, the baffle includes a fixing plate for fixing to the positioning segment and a positioning plate bent onto the fixing plate, the fixing plate having a degree of freedom to adjust its position on the positioning segment along the width direction of the positioning segment.

[0015] In one possible implementation, overlapping plates are fixedly installed on two opposing inner walls of the cavity, and a U-shaped groove is provided on the top of the overlapping plates, with the rotating shaft of the support roller overlapping inside the U-shaped groove.

[0016] In one possible implementation, an mounting plate is fixedly installed on the inner wall of the cavity, and a connecting plate is fixedly installed between the overlapping plate and the mounting plate, with the overlapping plate and the mounting plate arranged parallel to each other at intervals.

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the following: Figures 1 to 4 The anti-fall guide rail cutout support device provided by this utility model is described below. The anti-fall guide rail cutout support device includes a support frame 1, a placement platform 2, a support roller 3, a lever 4, and a pusher 5. The placement platform 2 is mounted on the support frame 1. Along its length, the placement platform 2 includes a support section 21 and a positioning section 22. The support section 21 has a downwardly recessed cavity, and the positioning section 22 is used to position the guide rail. The support roller 3 is rotatably disposed inside the cavity to support the guide rail. The lever 4 is hinged in the middle to the positioning section 22, and one end of the lever 4 can rotate out of the top surface of the positioning section 22 to lift the guide rail. The pusher 5 has its fixed end hinged to the positioning section 22 and its driving end hinged to the other end of the lever 4 to drive the lever 4 to rotate.

[0026] Compared with the prior art, the anti-fall guide rail cutting support device provided in this embodiment is equipped with a support frame 1, which includes two brackets that are respectively supported on the support section 21 and the positioning section 22. The top surface of the support section 21 is a downwardly recessed cavity, and the top surface of the positioning section 22 is a plane. A lever 4 is hinged below the positioning section 22, and one end of the lever 4 can rotate to the top of the positioning section 22. Furthermore, a pusher 5 for pushing the lever 4 to rotate is also installed below the positioning section 22. In this application, when cutting the guide rail, one end of the guide rail can be placed on the support section 21 and guided forward by the support roller 3 on the support section 21. The positioning section 22 positions the guide rail to complete the cut. Then, the pusher 5 pushes the lever 4 to rotate, which can lift the end of the guide rail located on the support section 21, making it convenient for the operator to hold the end of the guide rail. The other end of the guide rail is located on the support end and can be held by the cavity. This makes it easier for operators to remove the guide rail from the placement platform 2 after the guide rail is cut.

[0027] In some embodiments, the aforementioned dial 4 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 An elastic element 6 is also provided between the placement platform 2 and the lever 4 to pull the lever 4 downward. The elastic element 6 is a spring, with its two ends connected to one end of the lever 4 that extends out of the top surface of the positioning section 22, and the other end connected to the bottom of the positioning section 22, for pulling the lever 4 downward. The elastic element 6 can buffer the pushing force of the pusher 5 on the lever 4, reducing the impact on the guide rail when the lever 4 flips upward, thereby preventing the lever 4 from knocking the guide rail away when flipping upward.

[0028] In some embodiments, the aforementioned dial 4 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The lever plate 4 extends outward from the top of the positioning section 22, where a horizontal arm 41 is fixedly installed to increase the contact area with the guide rail. The length of the horizontal arm 41 is along the width of the positioning section 22. The horizontal arm 41 is installed at the end of the lever plate 4, and a clearance is provided at the top of the positioning section 22 to allow the horizontal arm 41 to pass over the lever plate 4. When the end of the lever plate 4 with the horizontal arm 41 is flipped upward, the horizontal arm 41 supports the bottom of the guide rail. This increases the support area for the guide rail, preventing it from tilting and falling onto the positioning section 22 when the guide rail is lifted, thus affecting the unloading of the guide rail.

[0029] In some embodiments, the aforementioned dial 4 can be adopted as follows: Figure 2 The structure shown. See also Figure 2The horizontal arm 41 has a cylindrical structure and is rotatably mounted on the lever plate 4. The middle part of the horizontal arm 41 is rotatably mounted on the lever plate 4, and support rollers 3 are fixedly installed at both ends of the horizontal arm 41 to support it to the bottom of the guide rail. The outer diameter of the support rollers 3 is larger than the outer diameter of the horizontal arm 41. When the lever plate 4 with the end containing the horizontal arm 41 swings upward, the support rollers 3 can abut against the bottom of the guide rail and roll below the lever plate 4 as the lever plate 4 rotates. This facilitates lifting the guide rail.

[0030] In some embodiments, the positioning segment 22 may be adopted as follows: Figure 1 , Figure 2 and Figure 3 The structure shown. See also... Figure 1 , Figure 2 and Figure 3 A baffle 7 is installed on the top of the positioning section 22 to position the guide rail along the width direction of the positioning section 22. The length direction of the baffle 7 is set along the length direction of the positioning section 22, and the baffle 7 is set perpendicular to the top surface of the positioning section 22. During the guide rail cutting process, the top of the guide rail can abut against the cutting mold to achieve positioning of the guide rail along its length direction. The side of the guide rail can abut against the baffle 7 to achieve positioning of the guide rail along the width direction of the positioning section 22, thereby facilitating the positioning of the guide rail cutting position and improving the production efficiency during the guide rail cutting process.

[0031] Specifically, in this embodiment, the positioning section 22 is located at the end of the support section 21 near the punch press. A cavity is recessed in the support section 21, which facilitates the operator to push the guide rail forward or backward through the gap between the cavity and the guide rail, making it easier for the operator to hold the guide rail. At the same time, a support roller 3 is also rotatably installed inside the support section 21, which can facilitate the forward movement of the guide rail.

[0032] In some embodiments, the baffle 7 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The baffle 7 includes a fixing plate 72 for fixing to the positioning section 22 and a positioning plate 71 bent and set on the fixing plate 72. The position of the fixing plate 72 on the positioning section 22 has the freedom to be adjusted along the width direction of the positioning section 22. The baffle 7 is made of angle steel. The two mutually perpendicular flanges of the angle steel are the fixing plate 72 and the positioning plate 71, respectively. A threaded hole for mounting the fixing plate 72 is provided at the top of the positioning section 22. An elongated through hole corresponding to the threaded hole is provided on the fixing plate 72. The length direction of the elongated through hole is set along the width direction of the positioning section 22. Thus, the position of the fixing plate 72 on the positioning section 22 along the width direction of the positioning section 22 can be adjusted. The position of the baffle 7 at the top of the positioning section 22 can be adjusted according to the width of the guide rail and the cut position.

[0033] In some embodiments, the support segment 21 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 Overlapping plates 31 are fixedly installed on two opposing inner walls of the cavity. A U-shaped groove is provided on the top of each overlapping plate 31, and the rotating shaft of the support roller 3 overlaps inside the U-shaped groove. Overlapping plates 31 are fixedly installed on both inner walls of the cavity along the width direction of the support section 21. A U-shaped groove is provided on the side of the top of each overlapping plate 31, and the projections of the U-shaped grooves on the two overlapping plates 31 along the width direction of the support section 21 coincide. When installing the support roller 3, the rotating shafts at both ends of the support roller 3 can be overlapped inside the U-shaped groove to achieve the installation of the support roller 3. The structure is simple and facilitates the installation of the support roller 3 onto the support section 21.

[0034] Specifically, in this embodiment, the support roller 3 includes a rotating shaft for mounting between two overlapping plates 31, and a roller rotatably disposed outside the rotating shaft.

[0035] In some embodiments, the aforementioned overlap plate 31 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 An mounting plate 32 is fixedly installed on the inner wall of the cavity. A connecting plate 33 is fixedly installed between the overlapping plate 31 and the mounting plate 32, and the overlapping plate 31 and the mounting plate 32 are arranged parallel to each other at intervals. The mounting plate 32 is also fixedly installed on the inner wall of the cavity by welding. A connecting plate 33 is fixedly installed at the bottom of the mounting plate 32, extending into the cavity. An overlapping plate 31 is fixedly installed on the side of the connecting plate 33 away from the mounting plate 32. When the rotating shaft of the support roller 3 is installed on the overlapping plate 31, the end of the rotating shaft of the support roller 3 abuts against the side of the mounting plate 32, thereby allowing the support roller 3 to be positioned along its axial direction.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
