Abstract
The invention discloses a falling protection device of a hoisting mechanism, comprising a fixing device, a safety push rod, a spacing ring and a tension spring, wherein the fixing device is vertically and fixedly connected to a base of the hoisting mechanism, the safety push rod horizontally penetrates through a guide hole of the fixing device, the spacing ring is fixedly connected with the right end of the safety push rod, the tension spring is arranged between the fixing device and the spacing ring and is sleeved on the safety push rod in a clearance way, and a traction steel rope horizontally penetrates through a positive stop device arranged at the right side of the spacing ring and is fixedly connected with the right end of the spacing ring. For adopting the falling protection device of the hoisting mechanism with simple structure, when the traction steel rope is lossened and broken, by utilizing the loss of the traction force, the tension spring externally applies the bite force to a clamping device through the safety push rod, and therefore, the hoisting mechanism can be more rapid, reliable and safe to lock a lifting guide rail to ensure that the hoisting mechanism can not fall.
Description
Technical field
The present invention relates to lift system, especially relate to the lift system falling protecting device.
Background technology
The main effect of lift system is that material or equipment are sent to eminence or are sent to lower from eminence from lower, and it has simple in structure, installs, removes and use advantages such as more convenient.For guaranteeing lift system safety in actual applications; people have studied multiple rope broken protector; what generally adopt now is the Wedge-type rope broken protector; its keystone configuration comprises a movable voussoir and fixing voussoir; but between the two along the inclined-plane slide relative; hanging basket connects with one of them voussoir; another voussoir is then with the guide rail double team; promote power and hang hanging basket by the load-bearing steel cable; hanging basket along guide rail vertical on; following motion when the load-bearing steel cable of hanging basket fractures, produces slide relative immediately because the tenesmus of hanging basket makes between two voussoirs; under the effect of sliding bevel; the voussoir of double team guide rail is clamped on the guide rail rapidly, and the inner face that clamps voussoir is the flank of tooth, and tightly guide rail is lived in interlock; hanging basket is unlikely because of disconnected rope falls, has guaranteed elevator safety in actual applications.
But there is following deficiency in above-mentioned rope broken protector: 1. when the slide relative between two voussoirs produced corrosion, the action sensitivity of rope broken protector reduced, and the whereabouts stopping distance surpasses the scope of national regulation, influences the safety of lift system structure; 2. use mechanism that installation environment is had certain requirement, can not use flexibly on comparatively simple, severe duty lift system.
Summary of the invention
The objective of the invention is to: a kind of more safe and reliable, lift system falling protecting device easily is provided.
For achieving the above object, the present invention can take following technical proposals:
Lift system falling protecting device of the present invention, it comprises the anchor fitting that vertically is fixed on the lift system base, level is passed the safety push-rod of described anchor fitting pilot hole, be fixed in the spacing ring of described safety push-rod right-hand member, be arranged between described anchor fitting and the spacing ring and the gap is sleeved on extension spring on the described safety push-rod; The pull line level is passed the inhibiting device that is arranged on described spacing ring right side and affixed with described spacing ring.
Also be provided with the electric elements that are used to detect described safety push-rod end position, the electric control system electrical interlocks of these electric elements and lift system.
Lift system falling protecting device of the present invention, adopt technique scheme, under described pull line traction state, tractive force is greater than the pulling force of extension spring, described safety push-rod moves to right, do not contact with gripping mechanism on the lift system, gripping mechanism and riser guide are the sliding block joint mode, lift system lifting flexibly; Under the disconnected state of described pull line pine, described safety push-rod moves to left and contacts with the gripping mechanism of lift system under described extension spring effect, applies a thrust for described gripping mechanism, at this moment, this gripping mechanism constitutes the mode that is connected with riser guide under thrust.Compared with prior art; the present invention is owing to adopted the simple above-mentioned lift system falling protecting device of structure; make lift system when pull line rope pine is disconnected; utilize the disappearance of tractive force; the snap-in force that extension spring adds for gripping mechanism one by safety push-rod; locking riser guide that can be quicker, reliable, safe, guaranteeing that lift system is unlikely falls.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, lift system falling protecting device of the present invention, it comprises the anchor fitting 2 that vertically is fixed on the lift system base 1, level is passed the safety push-rod 3 of described anchor fitting 2 pilot holes, be fixed in the spacing ring 4 of described safety push-rod 3 right-hand members, be arranged between described anchor fitting 2 and the spacing ring 4 and the gap is sleeved on extension spring 5 on the described safety push-rod 3; Pull line 6 levels are passed the inhibiting device 7 that is arranged on described spacing ring 4 right sides and affixed with described spacing ring 4.On described spacing ring 4, also be provided with the limit switch that is used to detect safety push-rod 3 end positions, the electric control system electrical interlocks of this limit switch and lift system.Under described pull line 6 traction states, tractive force is greater than the pulling force of extension spring 5, and described safety push-rod 3 moves to right, and does not contact with gripping mechanism 8 on the lift system, and gripping mechanism 8 is the sliding block joint mode with riser guide, lift system lifting flexibly; Under the disconnected state of described pull line 6 pines, described safety push-rod 3 moves to left and contacts with the gripping mechanism 8 of lift system under described extension spring 5 effects, applies a thrust for described gripping mechanism 8, at this moment, this gripping mechanism 8 constitutes the mode that is connected with riser guide under thrust.
