Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5 , an elevator pendulum clamping and releasing device, comprising a clamping mechanism, a clamping traction rope 4 and a releasing traction rope 5, the clamping mechanism comprising two clamping assemblies arranged opposite to each other, the clamping assemblies comprising a clamping jaw 1, a first connecting rod 2 and a second connecting rod 3, the clamping jaw 1 having a clamping portion 104, a first end 100, a second end 101 and a third end 102 from bottom to top, the first ends 100 of the two clamping jaws 1 are hinged, the second ends 101 of the clamping jaws 1 are hinged to the first connecting rod 2, the third ends 102 of the clamping jaws 1 are hinged to the second connecting rod 3 are hinged, the two first links 2 are hinged, the two second links 3 are hinged, the clamping traction rope 4 is used to pull the two first links 2 to reduce the angle between the two first links 2, and then drive the clamping parts 104 of the two clamping jaws 1 to approach each other through the two first links 2 to complete the clamping action, and the release traction rope 5 is used to pull the two second links 3 to reduce the angle between the two second links 3, and then drive the clamping parts of the two clamping jaws 1 to move away from each other through the two second links 3 to complete the release action.

[0029] It can be understood that in the above technical scheme, the utility model is provided with structures such as a clamping mechanism, a clamping traction rope 4, and a releasing traction rope 5. The clamping mechanism is driven by the clamping traction rope 4 to complete the clamping action, and the releasing action is driven by the releasing traction rope 5 to complete the releasing action, so that the operator can clamp and release the pendulum on the ground conveniently, avoiding the risk of accidentally injuring the test personnel after the pendulum hits the door and bounces up.

[0030] Continue reading Figure 1 In one embodiment of the utility model, the two first connecting rods 2 are hinged by a first pin 6, and the two first connecting rods 2 form an inverted V-shaped structure, and the clamping traction rope 4 is connected to the hook on the first pin 6.

[0031] Continue reading Figure 1 In one embodiment of the utility model, the two second connecting rods 3 are hinged by a second pin shaft 7, and the two second connecting rods 3 form an inverted V-shaped structure, and the release traction rope 5 is connected to the hook on the second pin shaft 7.

[0032] Continue reading Figure 2 and Figure 4, the first ends 100 of the two clamping jaws 1 are hinged by the third pin 8, the second end 101 of the clamping jaw 1 is hinged to the first connecting rod 2 by the fourth pin 9, and the first pin 6, the third pin 8 and the two fourth pins 9 constitute the four vertices of the rhombus. When the angle between the two first connecting rods 2 becomes smaller, the angle between the first ends 101 of the two clamping jaws 1 will naturally become smaller, thereby completing the clamping action.

[0033] Continue reading Figure 4 In one embodiment of the utility model, the clamping portion 104 of the two clamping jaws 1 is provided with a jaw 103. When the two clamping jaws 1 are closed, the two jaws 103 form a closed opening. The jaw 103 is used to limit the pendulum hook wire rope 10 inside, thereby clamping the pendulum hook wire rope 10.

[0034] The clamping traction rope 4 and the releasing traction rope 5 are preferably steel wire ropes.

[0035] The utility model is installed on a pendulum impact test device. During the test, the pendulum is first connected to the pendulum hook wire rope 10, and then the pendulum hook wire rope 10 is driven by the handwheel mechanism to pull the pendulum to a certain height, and then the pendulum is swung toward the direction of the utility model at a certain angle (to facilitate the swing of the pendulum to hit the door assembly), and then the pendulum hook wire rope 10 is placed in the jaws 103 of the utility model, and the clamping traction rope 4 is pulled. The clamping traction rope 4 drives the angle between the two first connecting rods 2 to become smaller, and the angle between the first ends 101 of the two clamping jaws 1 is also reduced, and the clamping parts 104 of the two clamping jaws 1 are close to each other to complete the clamping action. Afterwards, when it is necessary to release the pendulum, the release traction rope 5 is pulled, the clamping mechanism is opened, and the release traction rope 5 drives the angle between the two second connecting rods 3 to become smaller, so that the third ends of the two clamping jaws 1 are close to each other, so that the clamping parts 104 of the two clamping jaws 1 are away from each other, and then the pendulum hook wire rope 10 is released, so that the pendulum swings naturally and hits the door assembly.

[0036] It should be noted that the clamping traction rope 4 and the releasing traction rope 5 of the present invention have corresponding markings to facilitate identification by test personnel.
