Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a safety rope handrail for building steel structure construction. Background Art

[0002] High-altitude construction of steel structures is very dangerous. Generally, in order to ensure the personal safety of construction workers during high-altitude construction, a steel pipe about 1.2 meters long is welded to the steel beam, and then a safety rope is tied to the steel pipe. The safety belts carried by construction workers can be hung on the safety rope to walk back and forth. This method has some shortcomings: for example, welding steel pipes on steel beams requires fire, and after installation, the steel pipes must be cut off at high altitude using oxygen-acetylene flames. It also includes grinding, repair welding, and re-applying anti-corrosion paint on the cuts on the steel beams. High-altitude operation is extremely inconvenient, and the safety of construction workers who remove safety measures is difficult to guarantee.

[0003] At present, the Chinese patent with the existing patent application number CN201220399451.3 discloses a safety rope handrail for building steel structure construction, which is characterized by: a group of angle steel brackets are formed by fixing a vertical angle steel and a threaded round steel clamp through a nut to embrace the steel beam, and the top of the angle steel is provided with a fixing hole; a group of angle steel brackets are distributed at both ends of the steel beam, and the safety rope handrail passes through the fixing holes at the top of the angle steel and is fixed between the two groups of angle steel brackets. Construction workers can hang the safety belt they carry on the safety rope handrail to facilitate walking back and forth. Although the safety rope handrail can be installed on steel beams, steel trusses and other structures, due to its complex structure and the need to surround the H-shaped steel during installation, it takes a lot of time and effort to install it.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0005] The installation is cumbersome: Since the existing safety rope handrail is reinforced with a bolt structure, portable tools such as wrenches are required during installation, and most building steel structures are installed at higher positions. Therefore, special attention should be paid to the fixation of the tools during installation to prevent the tools from falling off. Secondly, since the existing safety rope handrail structure is fixed on the H-steel with an embracing structure (refer to the above-mentioned comparative document), and the H-steel has a certain thickness, the user needs to observe the relationship between the H-steel and the safety rope handrail components during installation, and the user is also required to squat or lie down to operate, which seriously affects the convenience and comfort of the safety rope handrail installation. For this reason, we propose a safety rope handrail for building steel structure construction. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a safety rope handrail for the construction of building steel structures.

After that, it is only necessary to connect the safety rope to the movable rod. The overall installation structure realizes the rapid installation of the safety rope handrail. Secondly, a limit assembly is used to maintain the positional relationship between the movable rod and the connecting rod, thereby maintaining the stability of the installation of the device, thereby solving the technical problem of cumbersome installation of existing safety rope handrails.

When the sleeve is sleeved at the hinge of the support rod 1 and the support rod 2, the support rod 1 and the support rod 2 cannot be bent due to the blocking effect of the sleeve. Figure 5 and Figure 6As shown, the fixation between the support rod 1 and the support rod 2 is completed.

[0016] Preferably, a limiting ring is sleeved on the outside of the support rod 1, and the limiting ring is connected to the inner wall of the sleeve via a spring. Figure 5 As shown, the elastic force of the spring on the sleeve is in the direction of the support rod 2, so that the sleeve can move toward the hinge between the support rod 1 and the support rod 2 under the elastic force of the spring;

[0017] Among them, a retaining ring is connected to the outer wall of the support rod 2, so that the sleeve can be blocked when it moves in the direction of the retaining ring. When the end of the sleeve is in contact with the retaining ring, the sleeve is mounted at the hinge between the support rod 1 and the support rod 2.

[0018] Preferably, the opposite ends of the support rod 1 and the support rod 2 are both connected with a butt joint, and a connecting rod is hinged between the two butt joints;

[0020] Preferably, both sides of the movable rod and both sides of the connecting rod are provided with notches, and the support rod 1 and the support rod 2 are both located in the notches.

[0022] Wherein, the clamping structure comprises a fixed cylinder, and one side of the fixed cylinder is connected to a conical extrusion cylinder, such as Fig.10 and Fig.11 As shown, this makes it easier to insert the safety rope, passing through the fixed tube from one end of the opening and then out from the other end of the fixed tube. Fig.12 As shown;

[0023] The extrusion cylinder includes an annular baffle, and a plurality of extrusion sheets are connected to the side of the baffle facing the fixed cylinder, and the plurality of extrusion sheets are arranged in a circular array, such as Fig.10 and Fig.11 As shown, a certain gap is reserved between two adjacent extrusion sheets to facilitate the folding of several extrusion sheets, thereby clamping and fixing the safety rope.

[0024] Preferably, the inner wall of the fixed cylinder is provided with a plurality of protrusions, and the protrusions are located in the gap between the two extrusion sheets, so that when the rotating cylinder is rotated, the extrusion cylinder inside it can move toward the direction of the fixed cylinder under the action of the thread, thereby clamping the safety rope.

[0025] Preferably, an extrusion block is connected to the inner side of the extrusion sheet, and the extrusion sheet is fitted to the outer wall of the safety rope through the extrusion block.

[0026] (III) Beneficial effects

At the same time, the device can be disassembled and installed without the use of tools, and the movable rod can be rotated to reduce the size of the device and improve its portability. In addition, in order to ensure the stability between the movable rod and the connecting rod, a limit assembly is set between the two to improve the stability of the device installation.

[0028] 2. Due to the threaded connection method, the rotating cylinder and the baffle are connected together, and an extrusion sheet is set on the side of the baffle facing the fixed cylinder.

[0047] The embodiment of the present application provides a safety rope handrail for building steel structure construction, which solves the technical problem of cumbersome installation of the existing safety rope handrail. The movable hook is driven to rotate by a movable rod and cooperates with the fixed hook at the end of the connecting rod to clamp the H-shaped steel. After that, the safety rope only needs to be connected to the movable rod, thereby realizing the rapid installation of the safety rope handrail. At the same time, the device can be disassembled and installed without using tools. The movable rod can also be rotated to reduce the size of the device and improve its portability. In addition, in order to ensure the stability between the movable rod and the connecting rod, a limit assembly is set between the two, thereby improving the stability of the device installation.

[0048] The rotating cylinder and the baffle are connected together by adopting a threaded connection, and an extrusion sheet is provided on the side of the baffle facing the fixed cylinder. The rotating cylinder is rotated to move the baffle toward the direction of the fixed cylinder. The extrusion sheet on the side wall of the baffle is squeezed and fixed to the safety rope at the center of the fixed cylinder by the extrusion of the fixed cylinder, thereby locking the safety rope and improving the stability of the safety rope installation.

[0049] Example 1

[0050] The technical solution in the embodiment of the present application is to solve the technical problem of cumbersome installation of the existing safety rope handrail. The overall idea is as follows:

[0051] In view of the problems existing in the prior art, the utility model provides a safety rope handrail for building steel structure construction, the safety rope handrail comprises a support frame 1 that can be connected to an H-shaped steel 4, and then the various support frames 1 are connected together through a safety rope 3, and the support frame 1 provides a supporting force for the safety rope 3, such as Figure 1 As shown, the main technical solutions of this application are as follows:

[0052] The movable rod 11 and the connecting rod 12 are hinged to each other, the connecting rod 12 is connected to the side wall of the movable rod 11, and the hinge point is located above the connecting rod 12, such as Figure 2-Figure 4 As shown, in this way, when the movable rod 11 and the connecting rod 12 are perpendicular to each other, the end of the connecting rod 12 and the movable rod 11 can be abutted against each other, as shown in FIG. Figure 2 and Figure 3 As shown, at this time, the connecting rod 12 cannot continue to rotate downward, thereby limiting the rotation position between the connecting rod 12 and the movable rod 11. In addition, this structure can also be used to achieve mutual folding between the connecting rod 12 and the movable rod 11, thereby reducing the size of the device and making it easier to carry.

[0053] In order to connect the device with the H-shaped steel 4, a movable hook 14 is connected to the bottom end of the movable rod 11, and corresponds to the fixed hook 13 at the end of the connecting rod 12, so that when the movable rod 11 and the connecting rod 12 rotate relative to each other, the fixed hook 13 and the movable hook 14 can be driven to rotate synchronously, thereby forming a "pliers"-like structure, which is convenient for clamping the H-shaped steel 4 later. Specifically, the connecting rod 12 is first placed above the H-shaped steel 4, and then the fixed hook 13 at the end of the connecting rod 12 is fitted with the edge of the H-shaped steel 4, as shown in FIG. Figure 7 As shown in (a), after completion, the movable rod 11 is rotated to drive the movable hook 14 to rotate synchronously, thereby blocking the other end of the H-shaped steel 4, as shown in FIG. Figure 7 (b) until the movable rod 11 is perpendicular to the connecting rod 12, forming a Figure 7 As shown in (c), at this time, the fixed hook 13 and the movable hook 14 are respectively connected to the two sides of the H-shaped steel 4, so as to clamp the H-shaped steel 4, thereby completing the fixation of the H-shaped steel 4.

[0054] In order to limit the position between the movable rod 11 and the connecting rod 12, a support rod 1 51 is connected to the outer wall of the movable rod 11, and a support rod 2 53 is connected to the connecting rod 12, and the opposite ends of the support rod 1 51 and the support rod 2 53 are hinged to each other. Figure 2-Figure 4 As shown, in order to limit the relative rotation between the support rod 1 51 and the support rod 2 53, a sleeve 52 is sleeved on the support rod 1 51. When the sleeve 52 is sleeved on the hinge of the support rod 1 51 and the support rod 2 53, the support rod 1 51 and the support rod 2 53 cannot be bent due to the blocking effect of the sleeve 52. Figure 5 and Figure 6 As shown, the fixation between the support rod 1 51 and the support rod 2 53 is completed, and due to the limited length between the support rod 1 51 and the support rod 2 53, the movable rod 11 and the connecting rod 12 connected thereto cannot rotate, so that the movable rod 11 and the connecting rod 12 always maintain a state of mutual disposal. Since the H-shaped steel 4 blocks the position of the movable hook 14 rotating backward, and the limit assembly blocks the position of the movable rod 11 rotating forward, the locking between the fixed hook 13 and the movable hook 14 is completed.

[0055] In order to maintain the tightness of the connection between the device and the H-shaped steel 4, an anti-skid protrusion (which can be made of rubber material) is provided on the opposite side of the fixed hook 13 and the movable hook 14, so that when the fixed hook 13 and the movable hook 14 clamp the H-shaped steel 4, the anti-skid protrusion on the inner side can fit with the edge of the H-shaped steel 4, thereby improving the fit between the device and the H-shaped steel 4 and preventing the device from moving on the H-shaped steel 4.

[0056] In order to improve the accuracy of the movement of the sleeve 52, a limiting ring 57 is sleeved on the outside of the support rod 51, and the limiting ring 57 is connected to the inner wall of the sleeve 52 through a spring. Figure 5 As shown, the elastic force of the spring on the sleeve 52 is toward the direction of the second support rod 53, so that the sleeve 52 can move toward the hinge between the first support rod 51 and the second support rod 53 under the elastic force of the spring.

[0057] Moreover, a retaining ring 54 is connected to the outer wall of the second support rod 53, so that the sleeve 52 can be blocked when it moves in the direction of the retaining ring 54. When the end of the sleeve 52 is in contact with the retaining ring 54, the sleeve 52 is sleeved at the hinge between the first support rod 51 and the second support rod 53.

[0058] In order to avoid mutual extrusion between the sleeve 52 and the retaining ring 54, a docking joint 55 is installed at the opposite end of the support rod 1 51 and the support rod 2 53, and a connecting rod 56 is hinged between the two docking joints 55, so that a certain gap can be reserved for the sleeve 52 and the retaining ring 54 when the support rod 1 51 and the support rod 2 53 are parallel to each other.

[0059] In order to ensure that the sleeve 52 can accurately move to the hinged position of the support rod 1 51, the connecting rod 56 and the support rod 2 53, when the movable rod 11 and the connecting rod 12 are perpendicular to each other, the support rod 1 51, the connecting rod 56 and the support rod 2 53 are exactly on the same central axis. Figure 2 and Figure 3 As shown, the sleeve 52 can move along the support rod 51 toward the hinge of the device.

[0060] In order to reserve a certain storage space for the support rod, so as to avoid the support rod from colliding with the movable rod 11 or the connecting rod 12 when folded, notches are provided on both sides of the movable rod 11 and both sides of the connecting rod 12, and the support rod 1 51 and the support rod 2 53 are both located in the notches. Figure 2-Figure 4 shown.

[0061] In the specific implementation process, the connecting rod 12 is first placed above the H-shaped steel 4, and then the fixing hook 13 at the end of the connecting rod 12 is fitted with the edge of the H-shaped steel 4. Figure 7 As shown in (a), after completion, the movable rod 11 is rotated to drive the movable hook 14 to rotate synchronously, thereby blocking the other end of the H-shaped steel 4, as shown in FIG. Figure 7 (b) until the movable rod 11 is perpendicular to the connecting rod 12, forming a Figure 7As shown in (c), at this time, the support rod 1 51, the connecting rod 56 and the support rod 2 53 are just on the same central axis, and the sleeve 52 sleeved on the support rod 1 51 moves toward the hinge between the support rod 1 51 and the support rod 2 53 under the elastic force of the spring, thereby covering the hinge between the two. Due to the blocking effect of the sleeve 52, the support rod 1 51 and the support rod 2 53 cannot be bent. Figure 5 and Figure 6 As shown, the fixation between the support rod 1 51 and the support rod 2 53 is completed. In addition, since the fixed hook 13 and the movable hook 14 are respectively connected to the two sides of the H-beam 4 and clamp the H-beam 4, the connection between the H-beam 4 and the device is completed.

[0062] Example 2

[0063] Based on Example 1, the embodiment of the present application provides a structure capable of reinforcing the safety rope to prevent the safety rope from being separated from the device. The overall idea is as follows:

[0064] The clamping structure 2 of the safety rope 3 is specifically as follows:

[0065] The clamping structure 2 includes a fixed cylinder 21, and a conical extrusion cylinder 23 is connected to one side of the fixed cylinder 21. Fig.10 and Fig.11 As shown, this makes it easier to insert the safety rope 3, passing through the fixed tube 21 from one end of the opening and then passing out from the other end of the fixed tube 21. Fig.12 As shown;

[0066] The extrusion cylinder 23 includes a circular baffle 231, and a plurality of extrusion sheets 232 are connected to one side of the baffle 231 facing the fixed cylinder 21. The plurality of extrusion sheets 232 are arranged in a circular array. Fig.10 and Fig.11 As shown, a certain gap is reserved between two adjacent extrusion sheets 232 to facilitate the folding of several extrusion sheets 232, thereby clamping and fixing the safety rope 3.

[0067] A rotating cylinder 22 is movably connected to one side of the fixed cylinder 21, and a connecting ring 24 is connected to one side of the fixed cylinder 21. The fixed cylinder 21 is connected to the rotating cylinder 22 through the connecting ring 24, and the two can rotate relative to each other but cannot be separated, so that the fixed cylinder 21 and the rotating cylinder 22 can rotate relative to each other. Since the rotating cylinder 22 is connected to the outer wall of the extrusion cylinder 23 by a thread, the extrusion cylinder 23 can be driven to move in the direction of the fixed cylinder 21 during the rotation of the rotating cylinder 22. In the process of the extrusion cylinder 23 moving toward the fixed cylinder 21, the extrusion sheet 232 on one side of the extrusion cylinder 23 is squeezed toward the center by the inner wall of the fixed cylinder 21, and the safety rope 3 at the center of the fixed cylinder 21 is squeezed, thereby locking the safety rope 3 to prevent the safety rope 3 from being separated from the device or loosening when the safety rope 3 is pulled.

[0068] In order to prevent the extrusion cylinder 23 from rotating synchronously with the rotating cylinder 22, a plurality of protrusions 25 are installed on the inner wall of the fixed cylinder 21, and the protrusions 25 are located in the gap between the two extrusion sheets 232. In this way, when the rotating cylinder 22 is rotated, the extrusion cylinder 23 inside it can move toward the direction of the fixed cylinder 21 under the action of the thread, thereby clamping the safety rope 3. Fig.11 As shown, the fixing of the safety rope 3 is completed.

[0069] like Fig.10 As shown, the inner side of the extrusion sheet 232 has an extrusion block (which can be made of rubber material), so that when the extrusion sheet 232 moves toward the direction of the safety rope 3, the extrusion block on it can squeeze the safety rope 3, thereby increasing the friction between the safety rope 3 and the extrusion sheet 232 to prevent relative sliding between the two.

[0070] In the specific implementation process, the safety rope 3 is first passed through one end of the fixed cylinder 21 with the rotating cylinder 22, and then passed through the other end of the fixed cylinder 21. At this time, the safety rope 3 is located in the area surrounded by the extrusion sheet 232, such as Fig.11 and Fig.12 Shown on the left.

[0071] The rotating cylinder 22 on one side of the rotating fixed cylinder 21 is connected to the extrusion cylinder 23 by a thread, and the protrusion 25 is located in the gap between two adjacent extrusion sheets 232 (so that the extrusion cylinder 23 cannot rotate). Therefore, the extrusion cylinder 23 moves toward the direction of the fixed cylinder 21 under the action of the thread, and in the process of movement, the extrusion sheets 232 are squeezed toward the center under the squeezing action of the edge of the fixed cylinder 21, and the safety rope 3 at the center is squeezed, thereby clamping the safety rope 3, thereby locking the safety rope 3 to prevent the safety rope 3 from separating from the device or loosening when the safety rope 3 is pulled.

[0072] 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.
