Description

A large-span safety rope barrier-free passage suspension device Technical Field

[0001] This utility model relates to the field of building construction, specifically a large-span safety rope barrier-free passage suspension device. Background Technology

[0002] During the installation of high-altitude, large-span supporting steel frame platforms, high-altitude welding operations are involved. To ensure construction safety, appropriate safety rope suspension devices are needed to provide attachment points for the safety ropes. Since there are no dedicated safety rope suspension devices, temporary support frames are typically erected on-site using steel plates or pipes at the edges of the operating platforms on both sides of the work area. These temporary support frames have safety hazards such as unstable structures and are not up to standard. The high-altitude operation safety rope suspension device application number "CN202221898551.0" solves the problem of no attachment points for the safety ropes during the installation of high-altitude, large-span supporting steel frame platforms. This invention also features a simple structure and is safe and reliable. Furthermore, the addition of casters facilitates the movement of the fixed frame after changes in attachment point positions. However, when hoisting composite slabs, workers wearing safety belts cannot move flexibly on the hoisting work surface. Each time workers move to a different work area, the safety belt extension rope needs to be adjusted, consuming significant manpower, resources, and time. Summary of the Invention

[0003] The purpose of this utility model is to provide a large-span safety rope barrier-free access suspension device to solve the problem mentioned in the background art that when hoisting composite slabs, workers wearing safety belts cannot move flexibly on the hoisting work surface, and the length of the safety belt extension rope needs to be adjusted every time the workers move to the work area, which consumes a lot of manpower, material resources and time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a large-span safety rope barrier-free passage suspension device, comprising a formwork support frame, a passage component, and an anti-detachment component;

[0005] Wherein: a support vertical tube is installed on the surface of the formwork frame, and a support horizontal bar is installed on the top of the support vertical tube;

[0006] The passage assembly includes a rotating cross disc rotatably mounted at the front end of a support crossbar. Four sets of support arms are fixedly mounted on the surface of the rotating cross disc. Each support arm has an operating handle fixedly connected to one end. Each support arm has a through hole on one end surface. The surfaces of the two sets of support arms facing downwards from the rotating cross disc are provided with pins. The pins are inserted into the through holes on the surfaces of the support arms facing downwards from the rotating cross disc. Safety ropes are inserted inside the two sets of support arms facing downwards from the rotating cross disc. The safety ropes are placed on the surfaces of the two pins. Safety belt hooks are slidably mounted on the surfaces of the safety ropes.

[0007] The anti-detachment component includes two symmetrically arranged mounting cavities inside the front end of the pin. A spring is connected inside the mounting cavity, and an anti-detachment block is slidably arranged inside the mounting cavity. The bottom of the anti-detachment block is connected to the spring.

[0008] As a preferred embodiment of this utility model: the top of the formwork support frame and the bottom of the supporting vertical tube, and the top of the supporting vertical tube and the tail end of the supporting horizontal bar are fixed by a fixed cross fastener.

[0009] As a preferred embodiment of this utility model: a diagonal brace is provided between the top of the supporting vertical tube and the supporting horizontal bar, and the diagonal brace is fixed to the top of the supporting vertical tube and the supporting horizontal bar by a rotating fastener.

[0010] As a preferred embodiment of this utility model: two limiting annular steel plates are installed at the front end of the supporting crossbar, and the rotating cross disc is installed between the two limiting annular steel plates.

[0011] As a preferred embodiment of this utility model, the bottom of the seat belt hook is connected to a binding strap.

[0012] As a preferred embodiment of this utility model, the tail end of the pin is equipped with an anti-slip grip.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When using it, the worker is strapped with a binding strap and slides on the safety rope through the safety belt hook. When the safety belt hook slides to the position of the support arm on the side of the rotating cross disc facing down, the pin on the surface of the support arm on the other side of the rotating cross disc facing down is pulled out. The rotating cross disc is rotated clockwise so that the support arm with the pin pulled out rotates to the top. The support arm that was originally close to the safety belt hook rotates to the position of the support arm with the pin pulled out first and lifts the safety rope through its own pin. That is, each set of support arms rotates to the position of the previous support arm. At this time, the safety belt hook is slid to the middle position of the two sets of support arms and the pin pulled out first is inserted into the through hole on the surface of the support arm that moves clockwise to the side of the rotating cross disc facing down. At this time, the safety rope is at the top of the two pins. The above operation is repeated in a cycle so that the safety belt hook passes through the rotating cross disc quickly. When assembling the structure and hoisting, the workers have a larger construction operation range and maintain the horizontal height and protective function of the safety rope.

[0015] (2) With the provided anti-detachment component, two mounting cavities are symmetrically opened inside the front end of the pin. Anti-detachment blocks are slidably installed inside the mounting cavities. When the pin passes through the through hole inside the support arm, the anti-detachment blocks are in an open state under the push of the spring to prevent the pin from detaching from the through hole. When it is necessary to pull out the pin, press the anti-detachment blocks to retract into the mounting cavity so that the pin is pulled out from the through hole. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figures 1-4. A large-span safety rope barrier-free passage suspension device includes: a formwork support frame 1, a passage component 4, and an anti-detachment component 5; a support vertical tube 2 is installed on the surface of the formwork support frame 1, and a support horizontal bar 3 is installed on the top of the support vertical tube 2.

[0023] Please refer to Figures 1 and 3. The passage assembly 4 includes a rotating cross disc 41 rotatably mounted at the front end of the support cross bar 3. Four sets of support arms 42 are fixedly mounted on the surface of the rotating cross disc 41. An operating handle 43 is fixedly connected to one end of each support arm 42. A through hole 44 is opened on the surface of one end of each support arm 42. The surfaces of the two sets of support arms 42 facing downward from the rotating cross disc 41 are provided with pins 45. The pins 45 are inserted into the through holes 44 on the surfaces of the support arms 42 facing downward from the rotating cross disc 41. A safety rope 46 is inserted inside the two sets of support arms 42 facing downward from the rotating cross disc 41. The safety rope 46 is placed on the surfaces of the two pins 45. A safety belt hook 47 is slidably mounted on the surface of the safety rope 46. A binding strap 10 is connected to the bottom of the safety belt hook 47.

[0024] In practical use: A rotating cross disc 41 is rotatably installed at the front end of the support cross bar 3. Four sets of support arms 42 are fixedly installed on the surface of the rotating cross disc 41. The four sets of support arms 42 are distributed in a cross shape on the outer ring of the rotating cross disc 41. An operating handle 43 is installed at one end of the support arm 42. A pin 45 is inserted into a through hole 44 opened at one end of the support arm 42. The safety rope 46 passes through the inside of the two sets of support arms 42 facing downwards from the rotating cross disc 41. When in use, the worker is secured with a binding strap 10 and slides on the safety rope 46 through the safety belt hook 47. When the safety belt hook 47 slides to the position of the support arm 42 facing downwards from the rotating cross disc 41, the pin 45 on the surface of the support arm 42 facing downwards from the rotating cross disc 41 is pulled out, and the rotating cross disc 41 is rotated clockwise. The support arm 42 with the pin 45 removed rotates upwards, while the support arm 42 that was originally close to the safety belt hook 47 rotates to the position of the support arm 42 with the pin 45 removed first, and lifts the safety rope 46 through its own pin 45. That is, each set of support arms 42 rotates to the position of the previous support arm 42. At this time, the safety belt hook 47 is slid to the middle position of the two sets of support arms 42, and the pin 45 that was removed first is inserted into the through hole 44 on the surface of the support arm 42 that moves clockwise to the downward-facing rotating cross disc 41. At this time, the safety rope 46 is located at the top of the two pins 45. The above operation is repeated in a cycle, so that the safety belt hook 47 quickly passes through the rotating cross disc 41. During the hoisting of the assembly structure, the workers have a larger working range and maintain the horizontal height and protective function of the safety rope 46.

[0025] Please refer to Figures 1 and 4. The anti-detachment component 5 includes two mounting cavities 51 symmetrically opened inside the front end of the pin 45. A spring 52 is connected inside the mounting cavity 51. An anti-detachment block 53 is slidably provided inside the mounting cavity 51. The bottom of the anti-detachment block 53 is connected to the spring 52.

[0026] In practical use: Two mounting cavities 51 are symmetrically opened inside the front end of the pin 45. Anti-disengagement blocks 53 are slidably installed inside the mounting cavities 51. When the pin 45 passes through the through hole 44 inside the support arm 42, the anti-disengagement blocks 53 are in an open state under the push of the spring 52 to prevent the pin 45 from disengaging from the through hole 44. When it is necessary to pull out the pin 45, press the anti-disengagement blocks 53 to retract into the mounting cavity 51, so that the pin 45 is pulled out from the through hole 44.

[0027] Please refer to Figure 1. The top of the formwork frame 1 and the bottom of the supporting vertical tube 2, and the top of the supporting vertical tube 2 and the tail end of the supporting horizontal bar 3 are fixed by a fixed cross fastener 6. A diagonal brace 7 is provided between the top of the supporting vertical tube 2 and the supporting horizontal bar 3. The diagonal brace 7 is fixed to the top of the supporting vertical tube 2 and the supporting horizontal bar 3 by a swivel fastener 8.

[0028] In practical use: the top of the formwork frame 1 and the bottom of the supporting vertical pipe 2, and the top of the supporting vertical pipe 2 and the tail end of the supporting horizontal bar 3 are all fixed by fixed cross fasteners 6. A diagonal brace 7 is provided between the supporting horizontal bar 3 and the supporting vertical pipe 2. The diagonal brace 7 is connected by a rotating fastener 8. The diagonal brace 7 strengthens the structural connection stability between the supporting vertical pipe 2 and the supporting horizontal bar 3.

[0029] Please refer to Figure 3. Two limiting ring steel plates 9 are installed at the front end of the support crossbar 3, and the rotating cross disc 41 is installed between the two limiting ring steel plates 9.

[0030] In practical use: two limiting ring steel plates 9 are installed at the front end of the support crossbar 3, and the rotating cross disc 41 is installed between the two limiting ring steel plates 9 to ensure that the rotating cross disc 41 rotates stably.

[0031] Please refer to Figures 2 and 4. The end of the pin 45 is fitted with a non-slip grip 11.

[0032] In practical use: the non-slip grip 11 installed at the end of the pin 45 makes it easy to hold the pin 45 stably.

[0033] During use, the worker is secured with harness 10 and slides the safety harness hook 47 onto the safety rope 46. When the safety harness hook 47 slides to the position of the support arm 42 facing downwards on the rotating cross disc 41, the pin 45 on the surface of the support arm 42 facing downwards on the other side of the rotating cross disc 41 is pulled out. The rotating cross disc 41 is then rotated clockwise, causing the support arm 42 with the pin 45 pulled out to rotate upwards. The support arm 42 that was originally closer to the safety harness hook 47 rotates to the position of the support arm 42 with the pin 45 pulled out first, and lifts the safety rope 46 through its own pin 45. The process begins with each support arm 42 rotating to the position of the previous support arm 42. At this point, the safety belt hook 47 is slid to the middle position of the two support arms 42. The first pin 45 that is pulled out is then inserted into the through hole 44 on the surface of the support arm 42 that is moving clockwise to the downward-facing position of the rotating cross disc 41. At this point, the safety rope 46 is located at the top of the two pins 45. The above operation is repeated cyclically, allowing the safety belt hook 47 to quickly pass through the rotating cross disc 41. During the hoisting of the assembly structure, the workers have a larger working range and the safety rope 46 is kept horizontal and its protective function is maintained.
