Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more specifically, relates to a safety belt bolting device for edge operations and a use method thereof. Background Art

[0002] With the rapid development of the modern construction industry, high-rise buildings and other engineering projects continue to emerge. The construction of high-rise buildings usually requires a large amount of high-altitude work on the outside of the wall, such as installing bay windows on high-rise buildings, painting and plastering the side walls, and working on the external balconies. These scenes are often accompanied by a large number of edge work needs. These areas often lack sufficient protective facilities, which poses a great threat to the life safety of construction workers. Traditional safety measures, such as setting up safety nets and building scaffolding, can ensure the safety of construction workers to a certain extent, but often have problems such as complex construction, high cost, and lack of flexibility. Especially in some special environments, such as narrow spaces and construction locations, the application of traditional safety measures is limited and it is difficult to meet actual construction needs. In order to more effectively ensure the safety of construction workers working on the edge, some new safety protection devices have appeared on the market in recent years, among which the edge operation safety belt bolt hanging device is one of them.

[0003] For example, the patent document with application number CN202410022859.6 provides a suspension auxiliary part. The device is provided with a base plate, a connecting through hole is provided on the base plate, a positioning part for connecting and fixing on the installation working surface is provided in the connecting through hole, a vertical pole is fixedly provided on the base plate, and the vertical pole is arranged vertically to the base plate, a rotating part is rotatably provided on the vertical pole, and the rotating part can rotate around the center line of the vertical pole, and a plurality of ring parts for hanging are provided on the rotating part. When performing aerial work, the base plate is pre-fixed on the installation working surface so that the base plate forms an installation foundation, and a stable connection foundation for safety measures is provided through a stable connection with the installation working surface. When the operator adopts safety measures such as hanging safety belts for protection, one end of the safety measures such as hanging safety belts is hung on the ring part to realize aerial work. In terms of personnel protection, on the one hand, the difficulty of arranging the bolting points can be reduced through the stable connection between the vertical pole and the positioning part. On the other hand, the rotating part can make the ring part rotate to different positions, so that the operators can work stably in different positions according to the needs of the operation, improving safety and reliability. In addition, multiple ring parts can provide multiple independent and stable hanging points for multiple operators, solving the problem that safety precautions cannot be fastened during high-altitude operations, greatly reducing the risk of employees falling from heights, and solving the problem of extending the maintenance time and increasing the maintenance costs due to the establishment of a safety maintenance platform. At the same time, it provides a simple, safe and reliable safety precaution technical solution for high-altitude operators, effectively preventing accidents that cause personal injury due to falling from heights, so as to better combine the safety and economy of high-altitude operations. However, the device needs to fix the bottom plate on the working surface in advance, which damages the existing structure, and the device structure is relatively complex and difficult to operate on site. Summary of the invention

[0004] In view of the above defects or improvement needs of the prior art, the present invention provides a safety belt bolting device for edge work and a method of use. By pressing the rebound fixing button and the retractable T-shaped ear plate, the device can be retracted into the telescopic rod, so that the device is small in size and easy to carry. By pulling the first telescopic rod to slide inside the second telescopic rod, and the rebound fixing button on the first telescopic rod is clamped in the fixing hole of the second telescopic rod, the overall length of the telescopic rod is preliminarily adjusted, and then fine adjustments are made through the fine-tuning rod to fully squeeze the anti-slip pad and the contact surface to increase friction and firmly fix the device, thereby realizing free adjustment of the height of the device and protecting the existing structure from damage.

[0005] In order to achieve the above-mentioned object, according to one aspect of the present invention, the present invention provides a safety belt hanging device for edge work, comprising a first telescopic rod, a second telescopic rod and a fine-adjustment rod, wherein the first telescopic rod is sleeved in the second telescopic rod, and the end of the second telescopic rod is connected to the fine-adjustment rod by a thread, wherein:

[0006] The first telescopic rod is provided with a plurality of rebound fixing buttons and a plurality of staggered retractable T-shaped ear plates at intervals, which can be retracted into the telescopic rod by pressing, so that the device can be retracted to reduce its volume and be convenient to carry;

[0007] The second telescopic rod is provided with fixing holes matching the rebound fixing button at intervals. The first telescopic rod is pulled to slide inside the second telescopic rod, and the overall length of the telescopic rod is preliminarily adjusted by clamping the rebound fixing button in the fixing hole. Then, the fine-tuning rod is used to make fine adjustments so that the elastic materials at the upper and lower ends of the device are squeezed and firmly fixed to the contact surface, thereby realizing free adjustment of the height of the device and protecting the existing structure from damage during the fixing process.

[0008] Furthermore, the first telescopic rod is a hollow high-strength steel tube, and an elastic upper anti-slip gasket is fixed to the top of the first telescopic rod.

[0009] Furthermore, a square hole having a position corresponding to that of the retractable T-shaped ear plate and having the same size as that of the retractable T-shaped ear plate is formed on the side wall of the first telescopic rod.

[0010] Furthermore, a circular hole corresponding to the position of the rebound fixing button and having the same size as the rebound fixing button is formed on the side wall of the first telescopic rod.

[0011] Furthermore, the rebound fixing button and the inner end of the retractable T-shaped ear plate are rigidly connected to the inner wall of the first telescopic rod through a built-in high-strength spring to achieve automatic pop-up and retraction.

[0012] Furthermore, the retractable T-shaped ear plate pops out in different directions and at different heights of the first telescopic rod, and a safety belt buckle bolt hanging hole is provided at its outer end, providing multiple all-round and reliable safety belt buckle hanging points for operators.

[0013] Furthermore, the second telescopic rod is a hollow high-strength steel tube, and a threaded sleeve connected to the fine-tuning rod is arranged at the bottom of the second telescopic rod.

[0014] Furthermore, the fine-tuning rod is a hollow high-strength steel rod with a self-locking thread on the upper portion and an elastic lower anti-slip gasket fixed to the bottom end.

[0015] Furthermore, a protruding fine-adjustment lever for fine-adjusting the length of the telescopic rod is fixed on the vertical surface of the fine-adjustment rod.

[0016] According to another aspect of the present invention, the present invention provides a method for using a safety belt fastening device for edge working, which is implemented by applying the above-mentioned safety belt fastening device for edge working, and the specific implementation steps are as follows:

[0017] S100: Preparation: Check whether the first telescopic rod, the second telescopic rod, the fine-adjustment rod and all connecting parts are intact, and determine in advance the working height that the telescopic rod needs to reach according to construction requirements;

[0018] S200: Coarse height adjustment: stretch the first telescopic rod until it reaches or approaches a predetermined height, complete the elongation and fixation of the rod, and check to make sure that the rebound fixing button is firmly inserted into the fixing hole to ensure construction safety;

[0019] S300: Height fine-tuning: Turn the fine-tuning lever on the fine-tuning rod to drive the fine-tuning rod to move in the vertical direction inside the second telescopic rod until the upper anti-slip pad and the lower anti-slip pad are in close contact with the building top plate and bottom plate respectively, and fix it after reaching the required height;

[0020] S400: Safety belt bolt hanging: Operators can choose the appropriate safety belt buckle bolt hanging hole from multiple retractable T-shaped ear plates according to the construction environment and personal needs, and hang the safety belt buckle on it;

[0021] S500: Device recovery: After the operation is completed, the built-in high-strength spring is compressed to retract the rebound fixing button and the retractable T-shaped ear plate, and the first telescopic rod is re-sleeved in the second telescopic rod to achieve rapid recovery and portability of the device.

[0022] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0023] 1. The edge working safety belt bolt hanging device of the present invention adopts a sleeve-type telescopic rod. By pulling the first telescopic rod to slide in the second telescopic rod, the rebound fixing button on the first telescopic rod automatically pops out and snaps into the fixing hole when it encounters the fixing hole on the second telescopic rod due to the elastic force of the built-in high-strength spring, thereby realizing the elongation and fixation of the rod, and fine adjustments can be made through the fine-tuning rod. The elongation height can be freely adjusted, which is suitable for a variety of construction scenarios, has high flexibility and wide applicability.

[0024] 2. The edge working safety belt bolt hanging device of the present invention is provided with elastic anti-slip pads on the top and bottom, and the anti-slip pads are in contact with the ceiling and the bottom plate of the room. The anti-slip pads are fully squeezed against the contact surface by rotating the fine-tuning rod to increase the friction and fix it firmly. The anti-slip pads are elastic materials and can play a buffering role, protecting the wall from scratches and damage, solving the problem that the existing device may cause damage to the existing structure during the fixing process, achieving the effect of firmly fixing the device without destroying the wall structure, and at the same time protecting the wall from scratches and damage, thereby improving the safety and cleanliness of the working environment.

[0025] 3. The safety belt fastening device for working at an edge of the present invention can provide multiple fastening points by staggeredly arranging multiple retractable T-shaped ear plates in different directions and at different heights on the first telescopic rod, thereby providing multiple all-round and reliable safety belt fastening points for workers, thereby realizing high-altitude working at the edge of different directions outside a building.

[0026] 4. The edge working safety belt bolting device of the present invention loosens the device by swinging the fine-adjusting lever to make the fine-adjusting lever move vertically upward, presses the rebound fixing button to retract it into the first telescopic rod, then retracts the first telescopic rod to a suitable height of the second telescopic rod, presses the retractable T-shaped ear plate to retract it into the first telescopic rod, and finally retracts the first telescopic rod completely into the second telescopic rod, completing the contraction of the device, reducing the size of the device, and making it easy to operate and convenient for operators to carry, and it can be reused in various construction scenarios.

[0037] like Figure 1 As shown, an embodiment of the present invention provides a safety belt bolting device for edge work, comprising a first telescopic rod 1, a second telescopic rod 2 and a fine-tuning rod 3, wherein the first telescopic rod 1 is sleeved in the second telescopic rod 2, and the end of the second telescopic rod 2 is connected to the fine-tuning rod 3 by threading. The first telescopic rod 1 is provided with a rebound fixing button 104 and a plurality of staggered retractable T-shaped ear plates 102, and the second telescopic rod 2 is provided with a fixing hole 201 matching the rebound fixing button 104, and the first telescopic rod 1 is pulled. During the pulling process, the rebound fixing button 104 of the first telescopic rod 1 can pop out of the fixing hole 201 fixed on the second telescopic rod 2, and the rod is extended. Then, the height of the extension rod is finely adjusted through the fine-tuning rod 3 at the bottom, so as to achieve telescopic adjustment of the height of the device, so as to be applicable to various construction stages and construction scene heights, increase the flexibility of the device, and make it more widely applicable. During the stretching process, the retractable T-shaped ear plate 102 automatically pops out at different heights and directions to provide multiple reliable safety belt fastening points for the workers, providing all-round safety protection for the construction workers.

[0038] like Figure 1-2 As shown, the first telescopic rod 1 includes an upper end anti-slip gasket 101 , a telescopic T-shaped ear plate 102 , an internal high-strength spring 103 and a rebound fixing button 104 .

[0039] The first telescopic rod 1 is a hollow high-strength steel rod with a diameter of 100 mm, and the upper anti-slip pad 101 with a diameter of 110 mm is fixed on the top thereof. The upper anti-slip pad 101 is made of elastic material and can play a buffering role when an object in contact with the wall moves, protecting the wall from scratches and damage;

[0040] A plurality of retractable T-shaped ear plates 102 are staggeredly arranged in different directions and at different heights inside the top of the first telescopic rod 1, and the inner end of the retractable T-shaped ear plate 102 is rigidly connected to the inner wall of the first telescopic rod 2 through the built-in high-strength spring 103. A square hole corresponding to the position of the retractable T-shaped ear plate 102 and having the same size as the retractable T-shaped ear plate 102 is opened on the side wall of the first telescopic rod 1 to enable the retractable T-shaped ear plate 102 to be ejected or recovered in different directions and at different heights along the side wall of the first telescopic rod 1 through the built-in high-strength spring 103. The exposed end of the retractable T-shaped ear plate 102 has a thickness of 20 mm, a length of 60 mm, and a width of 100 mm. A safety belt buckle bolt hanging hole is provided at the outer end, providing multiple all-round and reliable safety belt bolt hanging points for operators;

[0041] The rebound fixing button 104 is also arranged at intervals along the inside of the first telescopic rod 1, and its large-scale drawing is as shown in FIG. Figure 3 As shown, its diameter is 30mm, and its inner end is rigidly connected to the inner wall of the first telescopic rod 1 through the built-in high-strength spring 103. The side wall of the first telescopic rod 1 is provided with a circular hole corresponding to the position of the rebound fixing button 104 and having the same size, which has the same working principle as the retractable T-shaped ear plate 102. When the first telescopic rod 1 is retracted, the rebound fixing button 104 and the retractable T-shaped ear plate 102 are automatically retracted by the compression of the built-in high-strength spring 103. When the first telescopic rod 1 is stretched, the rebound fixing button 104 and the retractable T-shaped ear plate 102 are automatically ejected under the action of the built-in high-strength spring 103.

[0042] The second telescopic rod 2 is a hollow high-strength steel tube with a diameter of 110 mm, and a fixing hole 201 with the same size and the same arrangement spacing as the rebound fixing button 104 of the first telescopic rod 1 is opened on its side. By pulling the first telescopic rod 1, the rebound fixing button 104 on it is fastened to the fixing hole 201 to achieve the overall extension of the device, and a thread is set in the bottom of the lower telescopic rod 2.

[0043] like Figure 2 and Figure 4As shown, the fine-tuning rod 3 includes a lower end anti-slip pad 301 and a fine-tuning lever 302 .

[0044] The fine-adjustment rod 3 is a hollow high-strength steel rod with a diameter of 90 mm and a height of 500 mm, with a self-locking thread on the upper part and the lower anti-slip pad 301 fixed to the bottom. The lower anti-slip pad 301 is made of elastic material like the upper anti-slip pad 101 to protect the wall from scratches and damage. The fine-adjustment rod 3 is connected to the built-in sleeve at the lower end of the second telescopic rod 2 through the thread on the upper part. The raised fine-adjustment lever 302 is fixed on the vertical surface of the fine-adjustment rod 3. The fine-tuning rod 3 is driven to rotate by rotating the fine-tuning lever 302 along the vertical center line of the fine-tuning rod 302, and relative movement is generated between the internal thread of the fine-tuning rod 3 and the bottom thread of the second telescopic rod 2, thereby causing the adjustment rod to rise and fall inside the telescopic rod. This lifting and lowering movement causes the overall length of the telescopic rod to change, thereby achieving fine-tuning of the height of the device. During the fine-tuning process, the upper anti-slip gasket 101 and the lower anti-slip gasket 301 are fully squeezed against the top and bottom plates of the building, which greatly increases the friction between the contact surfaces and makes the device firmly fixed.

[0045] The working principle of the embodiment of the present invention is:

[0046] 1. Height adjustment principle:

[0047] In the initial state, the first telescopic rod 1 is sleeved in the second telescopic rod 2, and the rebound fixing button 104 and the retractable T-shaped ear plate 102 are both in the retracted state, and the built-in high-strength spring 103 is in the compressed state; when the height needs to be adjusted, the first telescopic rod 1 is pulled to slide in the second telescopic rod 2; as the first telescopic rod 1 is stretched, the rebound fixing button 104, when encountering the fixing hole 201 on the second telescopic rod 2, can automatically pop out and snap into the fixing hole 201 due to the elastic force of the built-in high-strength spring 103, so as to achieve the extension and fixation of the rod. The extended height can freely adjust the clamping position of the rebound fixing button 104 according to the construction needs. At the same time, during the stretching process, the retractable T-shaped ear plate 102 is also automatically popped out from different directions and different heights under the action of the built-in high-strength spring 103, providing multiple safety belt bolt hanging points for the operators.

[0048] 2. Principle of height fine-tuning:

[0049] When the height of the device needs to be fine-tuned, the fine-tuning lever 302 on the fine-tuning rod 3 can be rotated to drive the fine-tuning rod 3 to rotate, and relative movement will be generated between the thread inside the fine-tuning rod 3 and the thread at the bottom of the second telescopic rod 2, and the self-locking thread on the upper part of the fine-tuning rod 3 and the thread at the lower end of the second telescopic rod 2 are automatically locked and fixed, thereby achieving fine-tuning of the height of the device.

[0050] During the fine-tuning process, the upper anti-slip gasket 101 and the lower anti-slip gasket 301 are in contact with the building top plate and bottom plate respectively, and due to the characteristics of the elastic material, the friction between the contact surfaces can be increased, making the device more securely fixed.

[0051] 3. Safety belt bolt hanging:

[0052] The exposed ends of the retractable T-shaped ear plates 102 are provided with safety belt buckle bolt hanging holes, and the workers can hang the safety belt buckles on these bolt hanging points to achieve all-round safety protection. The staggered arrangement and multiple setting points of the retractable T-shaped ear plates 102 provide flexible choices for the workers, and they can choose the appropriate bolt hanging points according to the construction environment and personal needs.

[0053] 4. Recycling principle:

[0054] When the device is not needed or needs to be moved, the built-in high-strength spring 103 can be compressed to retract the rebound fixing button 104 and the retractable T-shaped ear plate 102, and the first telescopic rod 1 can be re-sleeved in the second telescopic rod 2 to achieve rapid recovery and portability of the device.

[0055] The safety belt bolt hanging device for working at an edge in the embodiment of the present invention achieves free adjustment of height and firm fixation through a first telescopic rod, a second telescopic rod and a fine-adjustment rod that are nested with each other. At the same time, retractable T-shaped ear plates in different directions and heights are used to provide workers with multi-directional and reliable safety belt bolt hanging points, thereby providing all-round safety protection for working at an edge.

[0056] Combination Figure 1-4 ,like Figure 5 As shown, an embodiment of the present invention provides a method for using a safety belt fastening device for edge work, which specifically includes the following steps:

[0057] S100: Preparation: Check whether the first telescopic rod 1, the second telescopic rod 2, the fine-tuning rod 3 and all connecting parts are intact, and predetermine the working height that the telescopic rod needs to reach according to construction requirements;

[0058] S200: Coarse height adjustment: stretch the first telescopic rod 1 until it reaches or approaches a predetermined height, complete the elongation and fixation of the rod, and check to make sure that the rebound fixing button 104 is firmly inserted into the fixing hole 201 to ensure construction safety;

[0059] S300: Height fine-tuning: If the height needs to be fine-tuned, the fine-tuning lever 302 on the fine-tuning rod 3 is rotated, and the fine-tuning rod 3 will drive the second telescopic rod 2 to rotate, and fix it after reaching the required height to achieve height fine-tuning; during the fine-tuning process, ensure that the upper anti-slip pad 101 and the lower anti-slip pad 301 are in close contact with the building top plate and bottom plate respectively to increase friction and make the device more securely fixed;

[0060] S400: Safety belt bolt hanging: The operator can select a suitable safety belt buckle bolt hanging hole from the multiple retractable T-shaped ear plates 102 according to the construction environment and personal needs, and hang the safety belt buckle on it;

[0061] S500: Device recovery: After the operation is completed, the built-in high-strength spring 103 is compressed to recover the rebound fixing button 104 and the retractable T-shaped ear plate 102, and the first telescopic rod 1 is re-sleeved in the second telescopic rod 2, so as to achieve rapid recovery and portability of the device.

[0062] In summary, the method for using the edge work safety belt fastening device provided by the embodiment of the present invention is simple and easy to understand, and convenient to operate. Through the height adjustment, fine-tuning function, and safety belt fastening steps, it can provide all-round safety protection for the workers. At the same time, the recycling and portability functions of the device also facilitate movement and storage during the construction process.

[0063] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
