Description

Technical Field

[0001] The utility model relates to the field of construction safety, in particular to a cable protection device for construction. Background Art

[0002] Construction elevators are usually called construction hoists, but the definition of construction elevators is broader, and construction platforms also belong to the construction elevator series. A simple construction elevator is composed of several parts such as a car, a drive mechanism, a standard section, a wall attachment, a chassis, a fence, and an electrical system. It is a construction machine that is often used to carry people and goods in construction. Due to its unique box structure, it is comfortable and safe to ride. Construction elevators are usually used in conjunction with tower cranes on construction sites. In order to avoid the breakage of the cable during use, a protective device needs to be installed.

[0003] The Chinese patent with the publication number CN2123875418U discloses a cable protection device for construction. The utility model includes a lifting frame, a motor is provided on one side of the lifting frame, a gear 1 is provided on the output shaft of the motor, a gear rod is meshed on the outer side of the gear rod, the gear rod passes through both sides of the lifting frame, a wire drum is provided, a steel cable is wound around the outer side of the wire drum, and the other end of the steel cable is connected to the hanging platform above the lifting frame, and a limit rod is provided at the bottom of the hanging platform. The utility model starts the motor, thereby rotating the wire drums at both ends of the gear rod to wind the steel cable, so that the lifting frame drives the user to rise. When operating the lifting frame to descend, the user can pinch the locking switch. When the steel cable breaks, the locking switch can be released. At this time, the locking switch fixes the lifting frame on the limit rod, which is safer and more convenient to use.

[0004] The above equipment is manually controlled during use. In the moment of an accident, the operator may not be able to make correct judgments and operations. The falling speed after breaking is fast and the reaction time is limited, so it still has certain risks. It has high requirements on psychological quality and reaction ability, and the applicable population is narrowed, which reduces the applicability of the equipment and needs to be optimized and improved.

[0033] After the set stretching cable 6 breaks, the equipment loses weight and the moving speed changes suddenly. The speed sensor 8 detects and controls the limit plug 12 to extend the support to limit the rotation of the connecting rod 1001. The outer rubber ring 1003 rubs against the inner wall of the external support frame, slowing down until it stops. The stretching cable 6 is connected to the inner side of the winding assembly 5, and then a detachable protective assembly 7 is connected between the winding assembly 5 and the stretching cable 6. Flexible protection is used to reduce the wear of the stretching cable 6 and reduce safety hazards.

[0034] Embodiment 2

[0035] On the basis of the first embodiment, a buffer pad 3 is provided at the bottom end of the lifting platform 1, and the bottom end of the lifting platform 1 is connected to the buffer pad 3;

[0036] When the lifting platform 1 moves up and down, the bottom can be buffered to reduce vibration and achieve a certain degree of protection performance.

[0037] Embodiment 3

[0038] On the basis of the second embodiment, a winding assembly 5 is provided on the outer side of the welding plate 4, and a tensile cable 6 is connected to the outer side of the winding assembly 5. The winding assembly 5 includes an inner shaft 501, a plug hole 502 and a side baffle 503. The outer wall of the inner shaft 501 is provided with a plug hole 502, and side baffles 503 are provided on both sides of the inner shaft 501. A protective assembly 7 is provided on the outside of the inner shaft 501, and the protective assembly 7 includes a rubber protective ring 701 and a plug connector 702.

Then the side baffle 503 is on the outside to limit the stretching cable 6 to prevent it from slipping out. The plug connector 702 is inserted into the socket 502 on the inner side of the inner rotating shaft 501, and the rubber protective ring 701 is fixed, so that a layer of protection can be formed between the inner rotating shaft 501 and the stretching cable 6 to reduce the wear of the stretching cable 6 during movement.

[0040] Embodiment 4

[0041] On the basis of the third embodiment, a speed sensor 8 is provided in the middle of the left side of the lifting platform 1, and rolling support frames 9 are provided on the left and right ends of the lifting platform 1, the inner side of the rolling support frame 9 is connected with a rolling assembly 10, and the inner front wall of the rolling support frame 9 is connected with a receiving tube 11, and the inner rear wall of the rolling support frame 9 is connected with a limited insertion rod 12, and the rolling assembly 10 includes a rotating connecting rod 1001, a connecting ring 1002 and a rubber ring 1003, the outer side of the rotating connecting rod 1001 is connected with a connecting ring 1002, and the outer side of the connecting ring 1002 is connected with a rubber ring 1003;

[0042] The rolling support frame 9 is connected on both sides, and then the internal connection is provided with a rotating connecting rod 1001 and a connecting ring 1002 that can provide rotation. A rubber ring 1003 is sleeved on the outer side of the connecting ring 1002. Support frames are arranged on both sides of the equipment. The rubber ring 1003 is squeezed on the inner wall of the support frame. When the connecting ring 1002 is rotatable, the rubber ring 1003 can continuously adjust the squeezing direction, which will not affect the lifting and moving of the equipment. When the stretching cable 6 breaks and the equipment loses weight, the speed of the equipment changes at this time and is fed back to the speed sensor 8, which then drives the limit plug 12 to extend and retract, so that the end of the limit plug 12 is inserted into the receiving tube 11, and the rotation of the connecting ring 1002 is limited. At this time, a single position of the rubber ring 1003 contacts the inner wall of the external support frame and continues to rub until it slows down and stops.

[0043] When the utility model is in use, firstly, the lifting and lowering of the lifting platform 1 is carried out by the stretching cable 6 moving on the outside of the inner rotating shaft 501. One end of the top of the stretching cable 6 is fixed, and the other side is wound and unwound by a winding device. Then the side baffle 503 is on the outside to limit the stretching cable 6 to prevent it from slipping out. Then the height is adjusted by winding and unwinding. The plug connector 702 is inserted into the plug hole 502 on the inner side of the inner rotating shaft 501, and the rubber protective ring 701 is fixed. In this way, a layer of protection can be formed between the inner rotating shaft 501 and the stretching cable 6 to reduce the wear of the stretching cable 6 during the activity. When the lifting platform 1 moves up and down, the bottom can be buffered to reduce vibration and achieve a certain degree of protection performance. The rolling support frame 9 is connected on both sides, and then the internal connection can provide a rotating connection for rotation. The connecting rod 1001 and the connecting ring 1002 are provided with a rubber ring 1003 on the outside of the connecting ring 1002. Support frames are provided on both sides of the movement of the lifting platform 1. The rubber ring 1003 is squeezed on the inner wall of the support frame. When the connecting ring 1002 is rotatable, the rubber ring 1003 can continuously adjust the squeezing direction, which will not affect the lifting and moving of the equipment. When the stretching cable 6 breaks accidentally, the equipment loses weight. At this time, the speed of the equipment changes and is fed back to the speed sensor 8. Then, the limit plug rod 12 is driven to extend and retract, so that the end of the limit plug rod 12 is inserted into the receiving tube 11 to limit the rotation of the connecting ring 1002. At this time, the single position of the rubber ring 1003 contacts the inner wall of the external support frame and continues to rub until it slows down and stops, thereby forcing the lifting platform 1 to stop to avoid danger caused by continuous descent.
