Description

Technical Field

[0001] The invention relates to the technical field of safety protection of steel structure construction sites, in particular to a locking device and a mounting device for a lifeline of a section steel column. Background Art

[0002] In recent years, with the mature application of steel structure technology, a large number of industrial plants have used portal steel frame structures, and a large number of production equipment have used frame steel frame structures. The portal steel frame structures and frame structure equipment have become larger and larger with the production process and the expectation of making full use of space. This has put forward higher requirements for the setting of safety devices in the steel structure installation process.

[0003] During the installation of steel structures, operators have to work at high altitudes, which is very dangerous. Operators face various risks when walking or operating on steel beams or purlins. Falling is the biggest risk and the consequences are the most serious. In order to ensure the safety of operators, a series of steel wire ropes will be temporarily installed on the high-altitude working surface of steel structures during the construction process. This temporarily installed steel wire rope is called "lifeline". At present, the installation of lifeline is widely used on construction sites. Operators buckle their safety belts on the lifeline when working at high altitudes. In case of an operator's slip and fall, the body can still hang on the lifeline and will not fall to the ground and cause a safety accident. When installing the lifeline of the traditional steel column, the steel wire rope is often wrapped around the column and fixed with a steel wire rope clip, which is easy to cause serious deformation of the lifeline, and the shear force at the bending part is large, which is easy to cause damage to the steel wire rope.

[0004] Based on this, the present invention provides a locking device and a mounting device for a lifeline of a steel column to solve the above-mentioned problem. Summary of the invention

[0005] The first object of the present invention is to provide a locking device for a steel column lifeline, which can ensure the locking of the steel lifeline without cutting the wire rope lifeline during installation, and has the advantages of more secure locking of the lifeline and convenient assembly and disassembly, etc., so as to solve the problems raised in the above background technology.

[0006] To solve the above problems, the present invention provides the following technical solutions:

[0007] A locker for the lifeline of a steel column, the locker comprising a locker body, a locking slider and a locking pin which can slide relative to the locker body, a locking pin fixing hole provided on the back of the locker body, a threaded hole provided on the back of the locking slider, the locking pin passing through the locking pin fixing hole and being threadedly connected with the threaded hole; a lifeline clamping upper groove is provided on the locker body, and a lifeline clamping lower groove is provided on the side of the locking slider adjacent to the lifeline clamping upper groove; the lifeline clamping lower groove is movably clamped with the lifeline clamping upper groove under the drive of the locking pin and clamps the lifeline; a number of anti-slip protrusions are provided in the lifeline clamping upper groove and the lifeline clamping lower groove.

[0008] The invention provides a locking device for a steel column lifeline, which also has the following technical features:

[0009] Furthermore, the top of the locker body is in a "concave" shape, and fixed guide rod sliding holes are provided on both sides of the "concave" shape of the locker body; and a sliding groove is provided at the bottom of the locker body.

[0010] Furthermore, the locking slider is T-shaped and passes through the sliding groove to be slidably connected to the locking device body.

[0011] Furthermore, at least one anti-slip protrusion is provided in each of the lifeline clamping upper groove and the lifeline clamping lower groove, and the lifeline clamping upper groove and the lifeline clamping lower groove are in a wave shape after being clamped.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

After clamping, the lifeline only undergoes a slight deformation, which ensures the locking of the lifeline without cutting off the lifeline, ensuring the continuity of the lifeline, providing good protection for the lifeline, and further ensuring the life safety of the construction workers;

[0014] 2) The inside of the lock has anti-slip protrusions, which increases the friction on the lifeline, making the locking effect of the lifeline more secure. At the same time, the shear stress on the lifeline is very small, which will not cause the lifeline to break suddenly, causing a safety hazard of falling from the building for high-altitude workers.

[0015] The second object of the present invention is to provide a device for installing a steel column lifeline, which can be applied to different types of steel when installing the steel lifeline, and has a good locking effect by locking the structural wing plate through the acute-angle wedge-shaped clamp block, and has a buffer device to ensure that the construction personnel can be protected when falling, so as to solve the problems raised in the above background technology.

[0016] To solve the above problems, the present invention provides the following technical solutions:

[0017] A device for erecting a lifeline of a steel column, the erection device comprising a mounting rod, a locking device mounted on the mounting rod, buffers being respectively provided at both ends of the locking device, a fixed clamping member being provided at one end of the mounting rod, and a sliding clamping member being provided at the other end of the mounting rod; one end of the sliding clamping member is the buffer member, and the other end is provided with an adjusting nut, the adjusting nut is threadedly connected to the mounting rod and can move back and forth relative to the mounting rod, wherein the locking device is the above-mentioned locking device.

[0018] Furthermore, the fixed clamping member is fixedly sleeved at the head end of the mounting connecting rod; the sliding clamping member is slidingly sleeved at the tail end of the mounting connecting rod, wherein the fixed clamping member is a fixed acute-angle wedge-shaped clamping block, and the sliding clamping member is a sliding acute-angle wedge-shaped clamping block.

[0020] Furthermore, the locker and the buffer are both located between the fixed clamping member and the sliding clamping member, and the locker is sleeved on the mounting connecting rod through a fixed guide rod sliding hole located at the top of the locker; wherein the buffer is a buffer spring.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) Through the sharp angle design of the fixed clamp and the sliding clamp, a locking structure is formed on the edge of the steel flange, which has a good locking effect and can be applied to different types of steel;

[0023] 2) The use of buffer springs has a good unloading effect on impact loads, which can protect workers working at heights when they fall, and can also provide good protection for the lifeline and the entire system;

[0024] 3) This patented product is small in size, light in weight, simple in structure, and easy to assemble and disassemble during use, thus avoiding the shortcomings of existing lifeline erection devices, which are large in size, heavy, inconvenient to install, and difficult to carry.

[0035] In the description of the present invention, it should be noted that the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] The following is combined with Figure 1 To Attachment Figure 5 And specific embodiments discuss the present invention in detail:

[0037] The present invention provides a locking device for the lifeline of a steel column, wherein the locking device 2 comprises a locking device body 21, a locking slider 22 and a locking pin 23 that can slide relative to the locking device body 21. In the scheme of the present invention, the locking pin 23 is cylindrical and has a thread in the middle. A locking pin fixing hole 211 is provided on the back of the locking device body 21, and a threaded hole 221 is provided on the back of the locking slider 22. The locking pin 23 passes through the locking pin fixing hole 211 and is threadedly connected with the threaded hole 221. It should be noted that there are multiple optional ways to drive the locking slider 22 to move toward the locking device body 21. In the preferred embodiment of the present invention, the locking pin 23 is passed through the locking pin fixing hole 211, and a threaded connection is achieved by cooperating between the thread on the locking pin 23 and the threaded hole 221 on the locking slider 22. When the locking pin 23 is tightened, the locking slider 22 will be driven to move toward the locking device body 21, and the locking slider 22 and the locking device body 21 form a locking clamp to lock the lifeline. The locking device body 21 is provided with a lifeline clamping upper groove 71, and a lifeline clamping lower groove 72 is provided on the side of the locking slider 22 adjacent to the lifeline clamping upper groove 71; the lifeline clamping lower groove 72 is movably engaged with the lifeline clamping upper groove 71 driven by the locking pin 23, and clamps the lifeline 8; the lifeline clamping upper groove 71 and the lifeline clamping lower groove 72 are both provided with a plurality of anti-slip protrusions 73, and when the locking slider 22 and the locking device body 21 form a locking clamp, the lifeline clamping upper groove 71 on the locking body 21 and the lifeline clamping lower groove 72 on the locking slider 22 are locked and clamped. The line clamping lower groove 72 is then clamped to form a lifeline clamping groove, and the lifeline clamping upper groove 71 cooperates with the anti-slip protrusion 73 in the lifeline clamping lower groove 72. The lifeline 8 is located in the lifeline clamping lower groove 72. As the lifeline clamping lower groove 72 cooperates with the lifeline clamping upper groove 71, the lifeline 8 is clamped. The clamping of the lifeline 8 through the anti-slip protrusion 73 will produce a tiny radial elastic bend, which increases the friction force, makes the clamping of the lifeline 8 more secure, and will not produce plastic deformation. The lifeline 8 does not need to be cut off, which not only achieves the purpose of locking, but also extends the service life of the lifeline 8.

[0038] Among them, the top of the locking device body 21 is in a "concave" shape, and fixed guide rod sliding holes 212 are provided on the two sides of the "concave" shape of the locking device body 21, which are used to cooperate with the lifeline erection device to protect the life safety of the workers at high altitudes; a sliding groove 213 is provided at the bottom of the locking device body 21, which is used to cooperate with the locking slider 22 to realize the up and down movement of the locking slider 22.

[0039] Among them, the locking slider 22 is T-shaped, and passes through the sliding groove 213 to be slidably connected with the locking device body 21. The T-shaped tail end of the locking slider 22 passes through the sliding groove 213 and will move up and down under the action of the locking pin 23 to achieve the clamping of the locking slider 22 and the locking device body 21.

[0040] Among them, at least one anti-slip protrusion 73 is provided in the lifeline clamping upper groove 71 and the lifeline clamping lower groove 72. The lifeline clamping upper groove 71 and the lifeline clamping lower groove 72 are wavy after being clamped. There are many ways to clamp the lifeline 8 in the present invention. Preferably, in this embodiment, the lifeline clamping upper groove 71 and the lifeline clamping lower groove 72 are clamped up and down and have anti-slip protrusions 73 inside. The locker 2 adopts this structure, which will cause a slight deformation of the lifeline 8 when clamped, thereby increasing the friction force, having a better locking effect on the lifeline 8, and extending the service life of the lifeline 8.

[0041] The present invention also provides a device for installing a lifeline of a steel column, the installation device includes an installation connecting rod 1, a locking device 2 sleeved on the installation connecting rod 1, the locking device 2 is used to lock the lifeline 8, preferably, the locking device 2 of the present invention has the advantage that it can directly lock the steel wire rope of the lifeline 8 without cutting the lifeline 8, thereby extending the service life of the lifeline 8; buffers 3 are respectively provided at both ends of the locking device 2, which can play a buffering and protective role for the workers when they accidentally fall from the steel during construction; a fixed clamping member 4 is provided at one end of the installation connecting rod 1, and a fixed clamping member 4 is provided at the installation connecting rod 1. The other end of the rod 1 is provided with a sliding clamp 5; one end of the sliding clamp 5 is movably connected to the buffer 3, and the other end is provided with an adjusting nut 9, the adjusting nut 9 is threadedly connected to the mounting link 1, and can move back and forth relative to the mounting link 1, the fixed clamp 4 is clamped with the edge of the steel column wing, and the movable adjusting nut 9 drives the sliding clamp 5 to move, so that the sliding clamp 5 is clamped with the other edge of the steel column wing, and the fixed clamp 4 and the sliding clamp 5 are locked on the steel column; wherein the locker 2 is the above-mentioned locker 2. In this embodiment, the material of the locker 2 is ZG300-500 cast steel, and its adjustable locking size range is 8-14mm.

[0042] Among them, the fixed clamping member 4 is fixedly sleeved on the installation connecting rod 1; the sliding clamping member 5 is slidably sleeved on the installation connecting rod 1, wherein the fixed clamping member 4 is a fixed acute-angle wedge-shaped clamp block 41, that is, the clamping angle of the fixed clamping member 4 is an acute angle, and the sliding clamping member 5 is a sliding acute-angle wedge-shaped clamp block 51, that is, the clamping angle of the sliding clamping member 5 is an acute angle. In the present invention, the fixed clamping member 4 and the sliding clamping member 5 can use various structures to clamp the steel column. This embodiment is a preferred embodiment. The fixed acute-angle wedge-shaped clamp block 41 and the sliding acute-angle wedge-shaped clamp block 51 are used, which can be applied to various steel structures of different models, and the locking effect is better. The material of the fixed acute-angle wedge-shaped clamp block 41 and the sliding acute-angle wedge-shaped clamp block 51 in this example is Q235B carbon steel, and the effective opening range between the fixed clamping member 4 and the sliding clamping member 5 is 0-400mm.

[0043] Among them, the fixing clamping member 4 is provided with a first pin hole 61, and the head of the mounting connecting rod 1 is provided with a second pin hole, and a fixing pin is provided between the first pin hole 61 and the second pin hole. There are many ways to fix the fixing clamping member 4 and the mounting connecting rod 1 in the present invention, such as welding together, fixing by bolts, etc. In this embodiment, the fixing clamping member 4 and the mounting connecting rod 1 are fixed by the fixing pin. This method has a better fixing effect. When the fixing clamping member 4 needs to be replaced, the use of welding as a fixing method will cause the entire device to be scrapped, and it also avoids the loosening caused by threaded connection, thereby losing the safety of the entire set.

[0044] Among them, the locker 2 and the buffer member 3 are both located between the fixed clamping member 4 and the sliding clamping member 5, and the locker 2 is sleeved on the mounting connecting rod 1 through the fixed guide rod sliding hole 212 located at the top of the locker body 21. In this embodiment, the specific connection sequence sleeved on the mounting connecting rod 1 is the fixed clamping member 4, the buffer member 3, the locker 2, the buffer member 3, the sliding clamping member 5, and the adjusting nut 9; wherein, the buffer member 3 is a buffer spring 31, and the buffer spring 31 is made of spring steel, which can more effectively buffer the impact load when the human body falls.

[0045] When the present invention is used on a steel column, the fixed clamping member 4 is used in conjunction with the sliding clamping member 5 to clamp the wing plate of the steel column, and the adjusting nut 9 is tightened to lock the product on the steel structure column. The lifeline 8 is placed in the lifeline clamping lower groove 72 of the locking device body 21 and the locking slider 22, and the locking pin 23 is rotated clockwise. Through the thread in the middle of the locking pin 23, the thread drives the internal thread set in the threaded hole 221 on the locking slider 22, so that the locking slider 22 approaches the locking device body 21, and the locking slider 22 and the locking body 21 form a locking clamp. At the same time, the lifeline clamping lower groove 72 will move upward with the locking slider 22, and cooperate with the lifeline clamping upper groove 71 located on the locking body 21 to lock the lifeline 8. After locking, under the action of the pre-tightening force, the locking slider 22 and the locker body 21 will squeeze the lifeline 8 into a wavy curve through the anti-skid protrusions 73 in the lifeline clamping upper groove 71 and the lifeline clamping lower groove 72. Three anti-skid protrusions 73 are respectively arranged in the grooves of the locking slider 22 and the locker body 21. The lifeline 8 achieves the locking purpose under the friction resistance of the anti-skid protrusions 73. The lifeline only produces a small radial elastic bend without plastic deformation. The lifeline does not need to be cut off, which achieves the purpose of locking and protects the lifeline. When this mounting device is used on a steel column, the device is installed on different columns at the same elevation. The lifeline 8 does not need to be cut off during installation, and continuous locking installation is performed according to the specifications for lifeline installation. If a worker working on the lifeline between two columns falls, the safety belt worn by the worker will cause the lifeline 8 to bend downward, and the lockers 2 located at both ends of the lifeline 8 will slide inward along the mounting connecting rod 1. When subjected to an impact load, the buffer 3 will immediately buffer and unload the impact load, thereby reducing the impact load on the lifeline 8 and protecting the lifeline, thereby protecting the lives of workers working at heights.
