[0014] (Three) beneficial effects

[0015] Compared with the prior art, the utility model provides a vertical cable laying anti-falling combined device, which has the following beneficial effects:

[0016] 1. In the process of cable laying, the cable passes through the cable ring and passes through the passage between the two valves. Under normal circumstances, the winch drives the cable to contract, the weight hammer is affected by the friction force of the cable and will not extrude the valve. When the cable falls due to some reason, the cable and the weight hammer will move downward quickly, the cable friction drives the valve to tighten, the weight hammer falls to extrude the valve inward, and the buffer height between the lower support structure and the well bottom can provide a certain buffer space for the cable falling, reduce the impact force when the cable falls, and the tightened valve works together to prevent the cable from falling to the bottom and causing serious damage.

The utility model discloses that the support rod is transmitted to the inclined support rod and the vertical support rod, and then the vertical support rod is transmitted to the support frame, and finally to the cable well wall. The load can be dispersed and transmitted, and the local stress is avoided. At the same time, the vertical support rod, the support rod and the inclined support rod jointly constitute a triangular structure.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Embodiment: please refer to Figures 1 to 5 According to the embodiments of the utility model, a technical scheme is provided: a vertical cable laying anti-falling combined device, comprising: a support structure, the support structure is installed on the upper layer and the lower layer of the cable well respectively, the support structure located at the lower layer leaves a height between the cable well bottom for cable falling buffer, the support structure comprises two support frames 1, the opposite side of the support frame 1 is fixed with a support rod 2, and the free end of the two support rods 2 is fixed with a connecting block 3; a cable ring 4 is fixed between the two connecting blocks 3 of the upper layer support structure, the cable ring 4 bottom is fixed with a rope 5, the gravity hammer 6 fixed on the rope 5, and the gravity hammer 6 is provided with a perforation 7; two valves 8, the valve 8 is in a half-cylinder shape, the outer side of the two valves 8 is fixed on the two connecting blocks 3 respectively, and the inner side of the two valves 8 is opposite to a cylinder shape and the upper opening is smaller than the lower opening.

[0027] ​It should be noted that the support structure height and width are adapted to the standard elevator shaft, the structure for pulling the cable up is a winch, the length of the rope 5 can be adjusted by the height between the two support structures, and the weight hammer 6 can be in contact with the valve 8 under the influence of gravity. Of course, in the above embodiment, the length of the rope 5 can also be freely controlled by installing a retractor to meet the installation requirements.

[0028] The vertical cable laying and falling prevention combined device with the above structure, in the process of cable laying, the cable passes through the cable ring 4 and passes through the passage between the two valves 8. Under normal circumstances, the winch drives the cable to contract, the weight hammer 6 is affected by the friction force of the cable and will not extrude the valve 8. When the cable falls due to some reason, the cable and the weight hammer 6 will move downward quickly, the cable friction drives the valve 8 to tighten, and the weight hammer 6 falls to make the valve 8 extrude inward. At the same time, the buffer height between the lower support structure and the bottom of the shaft can provide a certain buffer space for the cable falling, reduce the impact force when the cable falls, and work together with the tightened valve 8 to prevent the cable from falling to the bottom and causing serious damage.

[0029] The support rod 2 is embedded and slidably connected to the support frame 1, and the support frame 1 is provided with a sliding groove 9 for embedding and sliding of the support rod 2. Since the support rod 2 can slide in the sliding groove 9 of the support frame 1, the overall size of the support structure can be adjusted according to the actual width of the cable shaft. Different cable shafts may have different widths. Through this slidable connection mode, various sizes of cable shafts can be flexibly adapted, improving the universality and applicability of the device. During installation, the construction personnel can adjust the position of the support rod 2 on site according to the specific situation of the cable shaft, without the need for complex customization or modification of the support structure. This greatly simplifies the installation process and saves installation time and cost.

[0030] The support frame 1 is provided with an offset slot 10, and a vertical support rod 11 slides in the offset slot 10. The vertical support rod 11 is slidably connected in the offset slot 10, and an inclined support rod 12 is fixed between the vertical support rod 11 and the support rod 2. When the cable generates a load such as tension or gravity, the load is transmitted to the inclined support rod 12 and the vertical support rod 11 through the support rod 2, and then transmitted to the support frame 1 through the vertical support rod 11, and finally to the cable shaft wall. The load can be dispersed and transmitted, avoiding excessive local stress. At the same time, the vertical support rod 11, the support rod 2 and the inclined support rod 12 jointly form a triangular structure. According to the principle of triangular stability, the stability of the entire support structure can be effectively enhanced, so that the device is less likely to deform or be damaged when bearing the weight of the cable and various external forces that may occur.

[0031] The vertical support rod 11 passes through the slide groove 9 and is fixed to the support rod 2. When the vertical support rod 11 is not fixed to the support rod 2, the support rod 2 and the slide groove 9 need to be tightly fitted. Otherwise, the support rod 2 will easily tilt in the slide groove 9, making it difficult to slide. Therefore, the vertical support rod 11 is directly passed through the slide groove 9 and fixed to the support rod 2 to form a whole, which increases stability and makes it easier to slide and adjust the horizontal position of the support rod 2 in the elevator shaft.

[0032] A cable ring 4 is equipped with an upward movement monitoring module 13, which monitors the movement of the cable within the cable ring 4. By monitoring the cable's movement within the cable ring 4, construction personnel can promptly understand the cable's operating status and determine whether the cable is being laid smoothly at the predetermined speed and direction. If abnormal upward movement of the cable is detected, it may indicate that the cable is obstructed at a certain location, allowing construction personnel to quickly locate and address the problem. Conversely, when the cable moves rapidly downwards, an alarm can be issued in a timely manner to remind construction personnel to stop work and prevent safety accidents.

[0033] A support structure with cable ring 4 is installed on the top layer of the cable well, and a support structure with valve 8 is located on the next layer to increase the buffer height between the cable and the bottom of the cable well.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
