Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a safety hanging rope for construction engineering. Background Art

[0002] The engineering safety rope for construction workers is a key equipment to ensure their life safety when working at height. This kind of rope usually has the following characteristics: 1. Strong load-bearing capacity: It can bear the weight of construction workers and the weight of tools and materials that may be carried. 2. Comfort: It may be equipped with suitable hanging points to enable construction workers to maintain a comfortable posture when hanging and reduce fatigue. 3. Fire retardant: It uses flame retardant materials to increase safety in emergency situations such as fire. 4. Easy to operate: The design is simple and easy to understand, which is convenient for construction workers to tie and untie quickly without affecting work efficiency. 5. Color identification: There are usually obvious color identifications for easy identification and management. In addition, the use of safety ropes must be combined with correct installation and maintenance, and construction workers also need to receive relevant training to ensure correct use and operation. In this way, the safety of construction workers can be guaranteed to the greatest extent. The existing safety ropes can only be ropes of fixed length, which restrict the construction workers from moving their working positions and are not convenient for flexible use. Utility Model Content

[0003] In order to overcome the above technical problems, the utility model provides a safety hanging rope for construction engineering, which is used to improve the problem that the safety rope cannot be extended or retracted.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a safety lifting rope for construction engineering, including a lifting shell, a roller installed in the lifting shell and connected to the lifting shell bearing, a safety lifting rope wrapped around the roller and with one end protruding out of the shell, and an axle rod installed at the axis center of one end of the roller and protruding from the end face of the roller, a driving arm is hinged on the axle rod, and a return spring is provided at the connection between the driving arm and the axle rod, the end of the roller is movably connected with a top tooth, a slide rail is formed on the top tooth, one end of the connecting rod is slidably connected to the slide rail, and the other end of the connecting rod is hinged to the driving arm, an inner gear ring is fixedly installed in the shell, and the tooth mouth of the inner gear ring corresponds to the end of the top tooth.

[0005] The function of the lifting shell is to connect with the external scaffolding or safety fixing frame. Rollers are installed inside the lifting shell, and the safety rope is stored and wound on the rollers. One end of the safety rope extends out of the lifting shell and is fixed to the worker's safety belt.

[0006] When the worker pulls the safety rope at a normal speed, the driving arm will not open outwards under the pull of the return spring. When the worker falls accidentally, the safety rope will be quickly pulled out, and the driving arm will delay rotation under the action of inertia, driving the top teeth to open outwards through the connecting rod, holding the teeth of the inner ring, preventing the safety rope from being pulled out further, thereby pulling the falling worker and ensuring the personal safety of the construction workers.

[0007] The lifting shell is small in size, and the safety lifting rope occupies little space, which does not affect the construction and ensures the safety of construction workers with minimal space occupation.

[0008] Preferably, the top teeth are arc-shaped.

[0009] Setting the top teeth in an arc shape can make the force conversion reach the fixed axis of the top teeth more comprehensively after the top teeth are subjected to force at the top, and can also reduce the lateral shear force on the top teeth to avoid the top teeth from being broken.

[0010] Preferably, a weighted ball is provided at the end of the driving arm.

[0011] The counterweight ball can make it easier for the drive arm to delay rotation, better overcome the tension of the return spring, and make the drive arm drive the top gear to pop out faster and hold the gear mouth, thereby preventing the safety rope from being pulled out and protecting the life of the workers.

[0012] Preferably, the safety sling is a belt-shaped structure.

[0013] The safety sling is configured as a belt-shaped structure, which can save storage space when storing the safety sling. More safety slings can be wound in a unit cavity, thereby allowing construction workers to have more room to move during work.

[0014] Preferably, the return spring is a coil spring.

[0015] The use of coil springs can save installation space.

[0016] Preferably, a coil spring is provided between the roller and the hanging shell, with one end of the coil spring being fixed to the roller and the other end of the coil spring being fixed to the shell.

[0017] A coil spring is arranged between the roller and the lifting shell, so that the safety rope can be automatically stored when it is detached from the binding, and the safety rope is automatically recovered into the lifting shell under the drive of the coil spring.

[0018] The utility model provides a safety lifting rope for construction projects. When the safety lifting rope is quickly pulled out, the roller is driven to rotate. The driving arm is arranged to delay the rotation, so that the top teeth are driven to open outwards and press against the tooth openings, thereby blocking the rotation of the roller and locking the safety lifting rope so that it cannot be pulled out any further, thereby pulling the fallen workers and ensuring the life safety of the construction workers.

[0025] Embodiments of the present invention are described below with reference to the accompanying drawings. Elements and features described in one drawing or one embodiment of the present invention may be combined with elements and features shown in one or more other drawings or embodiments. It should be noted that for the purpose of clarity, the representation and description of components or processes that are not related to the present invention and are known to those of ordinary skill in the art are omitted in the drawings and descriptions.

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the utility model provides a safety lifting rope for construction engineering, including a lifting shell 1, a roller 2 installed in the lifting shell 1 and connected to the bearing of the lifting shell 1, a safety lifting rope 3 wrapped around the roller 2 and with one end protruding out of the shell, a shaft 4 installed at the axis center of one end of the roller 2 and protruding from the end face of the roller 2, a driving arm 5 is hinged on the shaft 4, a return spring 6 is provided at the connection between the driving arm 5 and the shaft 4, the end of the roller 2 is movably connected with a top tooth 7, a slide rail 8 is formed on the top tooth 7, one end of the connecting rod 9 is slidably connected in the slide rail 8, and the other end of the connecting rod 9 is hinged to the driving arm 5, an inner gear ring 10 is fixedly installed in the shell, and the tooth mouth of the inner gear ring 10 corresponds to the end of the top tooth 7.

[0028] The function of the hoisting shell 1 is to connect with the external scaffolding or safety fixed frame. The roller 2 is installed inside the hoisting shell 1. The roller 2 and the hoisting shell 1 can be connected through a bearing. The roller 2 can rotate in the front and back direction to store and release the safety rope 3. The safety rope 3 is stored and wound on the roller 2, and one end of the safety rope 3 extending from the hoisting shell 1 is fixed to the worker's safety belt.

[0029] When the worker pulls the safety rope 3 at a normal speed, the driving arm 5 will not open outwards under the pull of the return spring 6. When the worker falls accidentally, the safety rope 3 will be quickly pulled out, the roller 2 will rotate quickly, driving the shaft 4 to rotate. The shaft 4 rotates at a high speed, and the driving arm 5 has a certain weight. In the initial state, the force of the return spring 6 on the driving arm 5 is small, and the rotation will be delayed under the action of inertia. The top tooth 7 is connected to the end of the roller 2, and the top tooth 7 will quickly rotate with the roller 2. The delayed rotation of the driving arm 5 will pull the connecting rod 9, which drives the top tooth 7 to open outwards through the connecting rod 9, and presses against the teeth of the inner gear ring 10, preventing the safety rope 3 from continuing to be pulled out, thereby pulling the fallen worker and ensuring the personal safety of the construction personnel.

[0030] The lifting shell 1 is small in size, and the safety lifting rope 3 occupies a small space, which does not affect the construction, thereby ensuring the safety of the construction workers with minimal space occupation.

[0031] In one embodiment of the present invention, the top teeth 7 are curved in an arc shape.

[0032] Setting the top teeth 7 in an arc shape allows the force to be converted more completely to the fixed axis of the top teeth 7 after the top teeth 7 are subjected to force at the top, and can reduce the lateral shear force on the top teeth 7 to prevent the top teeth 7 from being broken.

[0033] In one embodiment of the present invention, a weighted ball 11 is provided at the end of the driving arm 5 .

[0034] The counterweight ball 11 can make it easier for the driving arm 5 to delay rotation, and can better overcome the pulling force of the return spring 6, so that the driving arm 5 can drive the top tooth 7 to pop out faster and hold the tooth mouth, thereby preventing the safety rope 3 from being pulled out, and protecting the life of the workers.

[0035] In one embodiment of the present invention, the safety rope 3 is a belt-shaped structure.

[0036] The safety rope 3 is configured as a belt-shaped structure, which can save storage space when storing the safety rope 3. More safety ropes 3 can be wound in a unit cavity, thereby allowing construction workers to have more room to move during work.

[0037] In one embodiment of the present invention, the return spring 6 is a coil spring.

[0038] The use of coil springs can save installation space.

[0039] In one embodiment of the present invention, a coil spring is provided between the roller 2 and the hanging housing 1, with one end of the coil spring being fixed to the roller 2 and the other end of the coil spring being fixed to the housing.

[0040] A coil spring is arranged between the roller 2 and the hoisting housing 1 , so that the safety rope 3 can be automatically stored when it is released from binding, and the safety rope 3 is automatically recovered into the hoisting housing 1 driven by the coil spring.

[0041] The utility model provides a safety lifting rope for construction projects. When the safety lifting rope is quickly pulled out, the roller is driven to rotate. The driving arm is arranged to delay the rotation, so that the top teeth are driven to open outwards and press against the tooth openings, thereby blocking the rotation of the roller and locking the safety lifting rope so that it cannot be pulled out any further, thereby pulling the fallen workers and ensuring the life safety of the construction workers.

[0042] Although the utility model and its advantages have been described in detail, it should be understood that various changes, substitutions and conversions can be made without exceeding the spirit and scope of the utility model defined by the attached claims. Moreover, the scope of the present application is not limited to the specific embodiments of the process, equipment, means, method and steps described in the specification. It will be easily understood by those of ordinary skill in the art from the disclosure of the utility model that according to the utility model, existing and future processes, equipment, means, methods or steps that perform substantially the same functions as the corresponding embodiments described herein or obtain substantially the same results as the corresponding embodiments described herein can be used.
