Description

Technical Field

[0001] The utility model relates to the technical field of safety protection products, in particular to a safety auxiliary device for preventing falling during indoor climbing and height operations. Background Art

[0002] Due to the influence of environmental factors during indoor climbing operations, medium and large indoor automated climbing equipment is difficult to enter the house. At this time, operators generally choose to climb a herringbone ladder to perform indoor high-altitude operations. When performing high-altitude operations indoors at a high height and a relatively large span, the operator will be at risk of falling after using the herringbone ladder to climb a height of more than 2 meters. In such a situation, an indoor retractable horizontal bar is generally used as a safety auxiliary device. The structure of the existing indoor safety auxiliary device is generally as follows: two adjustment rods are threadedly sleeved at both ends of the main body. When in use, the length of the horizontal bar is adjusted by twisting the two adjustment rods, so that it is fixed and supported between two walls, and then the safety belt is hung on the horizontal bar to improve the safety protection effect. However, when the above-mentioned indoor safety auxiliary device is installed and used, when encountering two support surfaces with a large span, it needs to be twisted dozens or hundreds of times to complete the fixed installation, and the operation efficiency is low.

[0003] The existing patent application number: 202121692157.7 discloses an indoor horizontal bar that is easy to tighten. When the device is installed and used, the telescopic rods at both ends are first twisted to make the two ends initially support the support surface, and then the rotating wrenches at both ends of the main body are held to rotate the main body relative to the telescopic rod, which is convenient for tightening and improving its installation firmness. In the above-mentioned prior art, the device still has the above-mentioned technical problems when performing installation and fixing operations. Utility Model Content

[0004] The purpose of the utility model is to provide a safety auxiliary device for preventing falling during indoor climbing and height operations, so as to solve the problem proposed in the above-mentioned background technology that when encountering two supporting surfaces with a large span, dozens or hundreds of turns are required to complete the fixed installation, resulting in low operating efficiency.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] like Figures 1 to 4 As shown, a safety auxiliary device for preventing falling during indoor climbing and height work includes a telescopic rod that can be telescopically fixed between the ground and the ceiling, and the telescopic rod includes:

[0030] A bottom support plate 12 is provided on the ground for expanding the support surface.

[0031] A first support rod 8 is disposed on the top of the bottom support plate 12 .

[0032] A screw rod 9 is provided between the bottom support plate 12 and the first support rod 8 for finely adjusting the height of the first support rod 8 .

[0033] The second support rod 4 is axially slidably sleeved on the top of the first support rod 8. The interior of the second support rod 4 is hollow. Both the second support rod 4 and the first support rod 8 are provided with a plurality of through holes 5 and locking holes 7. The locking holes 7 are used for fastening the safety belt.

[0034] The positioning pin 6 inserted into the through hole 5 is used to fixedly connect the first strut 8 and the second strut 4. The positioning pin 6 is in a T shape, which is convenient for applying force during assembly with the through hole 5.

[0035] The top circular seat 2 rotatably sleeved with the slot 10 provided at the top of the second strut 4 is provided with an annular groove 13. The top circular seat 2 is used to increase the supporting area between the ceiling and the second strut 4.

[0036] After the folding ladder is placed properly, the bottom support plate 12 can be placed on the ground near the folding ladder. Then, the positioning pin 6 is rotated counterclockwise and removed from the through hole 5. Next, the second strut 4 is pulled upward until the top circular seat 2 at its top abuts against the ceiling. If at this time, the through hole 5 on the first strut 8 does not coincide and is not coaxial with the through hole 5 on the second strut 4, the second strut 4 can be pushed downward into the first strut 8 until the through holes 5 on both of them coincide and are coaxial. Then, the positioning pin 6 is inserted into one end of the through hole 5 on the first strut 8 and passes through the through hole 5 on the second strut 4, and is threadedly connected to the through hole 5 on the second strut 4 until one end of the positioning pin 6 passes through the other end of the through hole 5 on the first strut 8, and the preliminary fixed installation is completed. Then, the first strut 8 is rotated so that the threaded mounting hole 11 at the bottom of the first strut 8 and the screw rod 9 at the top of the bottom support plate 12 rotate relative to each other, and the distance between the first strut 8 and the bottom support plate 12 is adjusted to be larger until the top of the top circular seat 2 tightly abuts against the ceiling. At this time, the fixed installation of the first strut 8 and the second strut 4 is completed. And before the operator climbs the folding ladder, the safety belt needs to be worn. When the operator climbs the folding ladder to a certain height, the buckle on the safety belt can be hooked into the buckle hole 7 at the corresponding height on the first strut 8 or the second strut 4, providing additional support for the operator, so that when an accidental fall occurs, the operator can be safely suspended on the first strut 8 or the second strut 4, avoiding the operator from falling to the ground and being injured, improving the safety protection effect. And during the process of fixedly installing the first strut 8 and the second strut 4 between the ceiling and the ground, the total height of the first strut 8 and the second strut 4 can be quickly adjusted to be closest to the distance between the ceiling and the ground by pulling. Then, by using the threaded connection relationship between the screw rod 9 and the first strut 8, the first strut 8 is rotated and made to rotate relative to the screw rod 9 and the bottom support plate 12 to adjust the distance between the first strut 8 and the bottom support plate 12, so as to quickly complete the fine adjustment and complete the entire fixed installation operation. By the combined use of the two length adjustment methods, the efficiency of the fixed installation operation is greatly improved.

[0037] In this embodiment, the telescopic rod further includes:

[0038] At least two spring buckles 3 are provided on the inner wall of the slot 10. One end of the spring buckle 3 is inserted into the annular groove 13. The spring buckle 3 is used for axially connecting the top circular seat 2 and the second support rod 4. After the length adjustment between the first support rod 8 and the second support rod 4 is completed, then turn the first support rod 8 and drive the second support rod 4 and the top circular seat 2 to rotate synchronously until the top of the top circular seat 2 abuts against the ceiling. Through the circumferential sliding connection design between the annular groove 13 and the spring buckle 3, when the first support rod 8 is continuously turned, the top circular seat 2 remains stationary, and the first support rod 8 and the second support rod 4 rotate synchronously until it is difficult to turn the first support rod 8 any further on the premise of not affecting the vertical straightness of the first support rod 8, so as to improve the support firmness between the first support rod 8 and the second support rod 4 between the ceiling and the ground.

[0039] In this embodiment, the through holes 5 and the locking holes 7 are distributed in a vertically staggered manner, and both the through holes 5 and the locking holes 7 penetrate the first support rod 8 or the second support rod 4 radially. The through holes 5 and the locking holes 7 are equidistantly distributed along the axial direction of the first support rod 8 or the second support rod 4. Such a design facilitates the operator to hang the safety belt worn on the body in the locking holes 7 at different heights according to the change of the climbing height, so as to expand the height application range and improve the safety assistance effect. And in case of accidental fall, the height change range of the operator's fall is smaller, so that the falling impact force is much smaller than the support upper limit of the first support rod 8 and the second support rod 4, thus improving the safety protection effect.

[0040] In this embodiment, the outer part of the positioning pin 6 is provided with an external thread, and the inner wall of the through hole 5 located on the second support rod 4 is provided with an internal thread, and the external thread matches the internal thread. Such a design is convenient for improving the connection stability between the first support rod 8 and the second support rod 4, avoiding the positioning pin 6 from being prone to move, which affects the firmness and stability of the fixed connection between the first support rod 8 and the second support rod 4, and improving the use safety.

[0041] In this embodiment, the bottom end of the screw rod 9 is fixed on the top of the bottom support plate 12, and the top end of the screw rod 9 is threadedly connected with the threaded mounting hole 11 provided at the bottom of the first support rod 8. Such a design, when finely adjusting the total height of the first support rod 8 and the second support rod 4, can turn the first support rod 8 and make it rotate relative to the screw rod 9 and the bottom support plate 12, so as to tighten the first support rod 8 and quickly reach the limit of its total height with the second support rod 4, facilitating the user to apply sufficient torque to the first support rod 8, so as to improve the firmness of the fixed installation.

[0042] In this embodiment, the telescopic rod further includes a top ceiling 1 fixed to the top of the top circular seat 2. The top ceiling 1 is located between the ceiling and the top circular seat 2. When the total height of the first strut 8 and the second strut 4 is finely adjusted, the friction between the top circular seat 2 and the ceiling can be increased, so that when the top circular seat 2 abuts against the ceiling, the user can continue to turn the first strut 8 and keep the top circular seat 2 from rotating, reducing the wear on the top of the top circular seat 2, and enabling the first strut 8 and the second strut 4 to firmly support between the ceiling and the ground.

[0043] The above are only the preferred embodiments of the present utility model. The parts not described in the present utility model can be implemented by adopting or referring to the existing technologies. Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present utility model should also fall within the protection scope of the present utility model.
