Example 1
Referring to fig. 1, 3 and 4, in embodiment 1 of the present invention, a structure diagram of an assembled building accessory hoisting protection device provided in the embodiment of the present invention includes: the device comprises a frame 1, a rotating speed recognition mechanism and a locking mechanism; the rotating speed recognition mechanism is arranged on the frame 1 and is used for recognizing the moving and descending speed of the lifting rope; the rotating speed identification mechanism comprises a guide wheel 2 and a coaxial wheel 16, and the coaxial wheel 16 and the guide wheel 2 are coaxially arranged; the guide wheel 2 is used for transmitting the rotating speed to the coaxial wheel 16; the lifting rope passes through the guide wheel 2, and the guide wheel 2 guides the lifting rope; the outer side of the coaxial wheel 16 is provided with an elastically arranged abutting piece 19, the outer side of the coaxial wheel 16 is provided with a switch 18, when the abutting piece 19 extends outwards in the high-speed rotation process of the coaxial wheel 16, the abutting piece contacts the switch 18, and the switch 18 transmits a high-speed signal to the locking mechanism;
The locking mechanism is arranged on the frame 1; the locking mechanism comprises clamping pieces 11 arranged on two sides of the lifting rope, the lower ends of the clamping pieces 11 on the two sides are rotatably arranged on the mounting frame 3, and the two clamping pieces 11 are used for clamping the lifting rope.
Specifically, when the speed of the lifting rope exceeds the limiting speed, the abutting piece 19 inside the coaxial wheel 16 stretches out of the coaxial wheel 16 under the action of centrifugal force, the abutting piece 19 contacts the switch 18 in the rotating process, the switch 18 transmits signals to the locking mechanism, and the locking mechanism controls the two clamping pieces 11 to be close to each other to lock the lifting rope; therefore, when the lifting rope is broken, the lifting rope can be locked timely, and falling or too fast falling can be prevented; thereby improving the safety of hoisting.
Example 2
Referring to fig. 3, the main difference between the present embodiment 2 and embodiment 1 is that at least one interference member 19 is provided, so that a plurality of interference members 19 are provided in order to ensure that the rotation speed can be transmitted in time. And further can timely transmit the information.
As a preferred embodiment of the invention, in order to achieve that the two clamping members 11 can be brought close to each other when a high speed signal is received, the positions of the two clamping members 11 can be connected by a hydraulic cylinder, and when a signal is received, the hydraulic cylinder contracts to bring the two clamping members 11 close to each other to clamp the lifting rope.
Referring to fig. 1, as another preferred embodiment of the present invention, an adsorption assembly is disposed between the mounting frame 3 and the clamping members 11, and the two clamping members 11 are connected by a second elastic member 8, when a high-speed signal is received, the adsorption assembly is disconnected, and the two clamping members 11 approach each other under the action of the second elastic member 8 and then clamp the lifting rope. Specifically, the adsorption component comprises a first adsorption element 7 and a second adsorption element 9, wherein the first adsorption element 7 is fixedly arranged on the mounting frame 3, the second adsorption element 9 is fixedly arranged on the clamping element 11, when a high-speed signal is received, the first adsorption element 7 is powered off, attractive force between the first adsorption element 7 and the second adsorption element 9 disappears, the clamping element 11 is close to the lifting rope under the action of the second elastic element 8, the lifting rope is clamped, and the lifting rope stops falling. The first absorbing member 7 and the second absorbing member 9 may be electromagnets or suckers that attract each other.
In order to realize that the abutting piece 19 is elastically installed on the coaxial wheel 16, the abutting piece 19 passes through a through hole on the coaxial wheel 16, the abutting piece 19 is fixedly installed on the third elastic piece 20 at one end inside the coaxial wheel 16, and the other end of the third elastic piece 20 is fixedly installed on the coaxial wheel 16, so that the abutting piece 19 overcomes the acting force of the third elastic piece 20 in the high-speed rotation process, and further leaks more outwards, and further can touch the switch 18 in the rotation process, if the coaxial wheel 16 rotates at a low speed, the abutting piece 19 leaks less, and therefore the switch 18 cannot be touched in the rotation process.
The switch 18 is fixedly mounted on the mounting member 17, and the mounting member 17 is fixedly mounted on the frame 1. The switch 18 is in communication with the locking mechanism. Both may be connected by wireless or wired connection.
The first elastic member, the second elastic member, and the third elastic member mentioned in the present application may be leaf springs or coil springs.
Referring to fig. 1 and 2, as a preferred embodiment of the present invention, in order to prevent the suspended object from shaking during the locking of the hanger rope by the clamping member 11, a stabilizing wheel 14 is provided under the locking mechanism, the hanger rope is wound around the stabilizing wheel 14, and the stabilizing wheel 14 is rotatably mounted on the frame 1.
Further increasing the stability of the hoisting rope, a limiting mechanism for limiting the rotation of the stabilizing wheel 14 is thus provided between the locking mechanism and the stabilizing wheel 14.
As a preferred embodiment of the invention, the limiting mechanism comprises a mounting rod 12 arranged at the bottom of the mounting frame 3, at least one elastic rod 13 is arranged at the bottom of the mounting rod 12, the elastic end of the elastic rod 13 is abutted against the end surface of the stabilizing wheel 14, and the end surface of the stabilizing wheel 14 is also provided with a limiting groove 15 for sliding in the elastic rod 13; the mounting frame 3 slides up and down and is elastically arranged on the frame 1. Specifically, when the clamping pieces 11 on the two mounting frames 3 are close to each other to clamp the lifting rope, the mounting frames 3 are under the influence of falling of the lifting rope, the mounting frames 3 slide downwards, the mounting frames 3 drive the elastic rods 13 on the mounting rods 12 to move downwards, the elastic rods 13 slide into the limiting grooves 15 in the downward movement process, the rotation of the stabilizing wheels 14 is further limited, and further shaking of the lifting rope can be reduced better, so that the use safety is improved.
In order to enable the installation frame 3 to be arranged on the installation frame 3 in a vertical sliding mode, sliding pieces 4 are fixedly arranged on two sides of the installation frame 3 respectively, the sliding pieces 4 are arranged in the frame limiting grooves 15 in a vertical sliding mode, the installation frame 3 can slide up and down in this way, and other sliding mechanisms in the prior art can be adopted for realizing the vertical sliding of the installation frame 3.
In order to achieve a resilient arrangement of the mounting frame 3 on the frame 1, the mounting frame 3 is thus mounted on the frame 1 by means of the first resilient member 6, which first resilient member 6 may be arranged on the upper side or on the lower side of the mounting frame 3.
In order to limit the rotation of the stabilizing wheel 14 during the stop of the descent, it is also possible to use a locking disc which is mounted on the frame 1 and can be brought close to the stabilizing wheel 14 by means of a hydraulic cylinder, locking it.
The working principle of the invention is as follows: when the falling speed of the lifting rope is too high, the guide wheel 2 is driven to the coaxial wheel 16 at a high speed, the coaxial wheel 16 rotates in an accelerating way, the centrifugal force received by the abutting piece 19 is too high, then the switch 18 is touched in the rotating process along with the coaxial wheel 16, signals are transmitted to the first absorbing piece 7 and the second absorbing piece 9 in the locking mechanism by the switch 18, then suction force is lost between the first absorbing piece 7 and the second absorbing piece 9, the two clamping pieces 11 are mutually close to clamp the lifting rope under the action of the second elastic piece 8, the lifting rope is limited to fall, the two clamping pieces 11 drive the mounting frame 3 to slide downwards under the action of the lifting rope, the mounting frame 3 drives the elastic rod 13 on the mounting rod 12 to move downwards in the downward sliding process, and the elastic rod 13 slides into the limiting groove 15 in the downward moving process, so that the rotation of the stabilizing wheel 14 is limited; further, shaking of the lifting rope can be reduced better, and further use safety is improved.
