Abstract
The utility model relates to a falling preventing device. Four falling preventing chains are fixed with the four corners of a lifting base board, the falling preventing chains are connected with a brake which is composed of a ratchet wheel and a ratchet pawl, and the brake is connected with a broken rope annunciator on the base surface of the lifting base board through a travel switch. When a broken rope or a broken shaft or other accident occurs, the lifting base board can be instantaneously suspended and stopped, so that a stored vehicle can be guaranteed to be safe and undamaged. The device has the advantages of simple structure, low cost, and flexible and reliable actions for a braking member. The utility model is especially suitable for various lifters on which guide rails can not be arranged.
Description
The utility model relates to the anti-drop device technical field.
In lifting type multi-storied garage, the lifting base plate of bicycle parking position, top is fallen during bicycle parking to enter the track concordant, treat that vehicle sails base plate into after, base plate rises to certain position, forms the top bicycle parking.Usually the lifting of base plate is that reel by hoist engine drives four lifting steel cables that are fastened on four jiaos of lifting base plates and realizes.When the lifting base plate is suspended from upper position or in lifting process, just in case when contingency such as the disrumpent feelings or hoist engine off-axis of steel cable takes place, will cause great damage to depositing vehicle.
Existing anti-drop device all is equipped with the braking guide rail, complex structure, and the cost height, and can't be used for up-down cross sliding type multi-storied garage.
The purpose of this utility model provides a kind of brakeless guide rail anti-drop device, when contingencies such as disconnected rope of generation or off-axis, the instantaneous outstanding system of lifting base plate can be lived, and guarantee the safety and nondestructive of the vehicle of depositing.
The purpose of this utility model is achieved through the following technical solutions: but anti-drop device has the lifting base plate of a storage of cars, the lifting steel cable that base plate is four jiaos connects with hoist engine, the lifting base plate fixedly position of lifting steel cable is equipped with anti-fall chain, the corner sprocket that anti-fall chain and is sleeved on the back shaft cooperates connection, ratchet also is housed on the back shaft, the ratchet and pawl of coupling constitutes brake mutually, and this brake connects by travel switch with the disconnected rope signalling means that is loaded on lifting base plate bottom surface.
Ratchet in the described brake connects by a connecting rod and shifting block, and shifting block and coaxial ratchet are installed; Disconnected rope signalling means has a tapered sleeve that is bound up with lifting steel cable bottom, and tapered sleeve and a double-screw bolt that is socketed with spring connect, and the double-screw bolt other end is positioned at the place ahead of travel switch contact.
Below in conjunction with embodiment and accompanying drawing thereof utility model is described further.
Fig. 1 is the anti-fall structural representation of lifting base plate bicycle parking in the lifting type multi-storied garage.
Fig. 2 is the structural representation of disconnected rope signalling means.
Fig. 3 is the structural representation of brake.
As shown in Figure 1, brakeless guide rail anti-drop device is four jiaos of lifting base plate 1, the fixing position of lifting steel cable, be fixed with four anti-fall chains 4, corner sprocket 6 backs that chain is walked around the suspension sprocket wheel 7 that is contained on the longeron 5 and longeron end link with balancing weight 3, each sprocket wheel is supported by the back shaft that is linked on the longeron, and longeron is supported by front and back column 2.During lifting base plate operate as normal, with the base plate lifting, each sprocket wheel freely rotates on back shaft chain by the balancing weight pulling.
As shown in Figure 2, disconnected rope signal component is installed in lifting base plate bottom surface.The corner wheel 9 that is bound up on the minor axis 8 is equipped with in the restraint location bottom of every lifting steel cable 10 on the base plate.Steel cable 10 is walked around corner wheel 9 backs and is fixedly linked with tapered sleeve 11, the tapered sleeve other end connects with the double-screw bolt 12 that is fixed in the supporting base 14, the clamp nut 17 that is connected in the double-screw bolt rear end is anchored on spacer 16 and spring 15 on the double-screw bolt section between supporting base and nut, be positioned at the adjusting nut 13 behind the tapered sleeve, effect is a stroke of regulating double-screw bolt.When normal condition, spring is compressed by the pulling force of lifting steel cable and is in compressive state.When disrumpent feelings the or hoist engine off-axis of steel cable takes place, steel cable loses pulling force, spring is pushed double-screw bolt to travel switch 18 immediately and is pressed on its contact, make switch closure, produce signal of telecommunication control hoist engine and stop, brake action simultaneously, anti-fall chain braking, the lifting base plate is lived by the outstanding system of anti-fall chain at once, has guaranteed to stop having the lifting base plate of vehicle can run-off the straight or tenesmus accident.Travel switch is selected model JW 2A-11 press-contacting type switch for use.
As shown in Figure 3, brake components adopts the click structure.Combine as a whole with the corner sprocket 6 and the ratchet 20 of anti-fall chain 4 engagements, be enclosed within on the back shaft 19, the ratchet 23 that is installed on the pivot pin 22 connects by connecting rod 24 and shifting block 21.Under the normal condition, shifting block 21 is in position shown in the dotted line among the figure, and connecting rod struts ratchet and makes it not contact with ratchet, and this moment, ratchet freely rotated on axle 19 together with corner sprocket, and chain is then with the upper and lower lifting of base plate freedom.When disconnected rope or off-axis take place when, the travel switch action, drive magnet is unclamped claw, and extension spring makes shifting block turn to solid line position among the figure.Connecting rod pulling this moment ratchet to and ratchet engaged, ratchet is blocked, ratchet and corner sprocket all can not rotate, and are braked immediately with the anti-fall chain of sprocket engagement, and the outstanding system of lifting base plate is lived.The every anti-fall chain that is installed in four jiaos of lifting base plates all has a brake, and four brakes move simultaneously during braking.
The anti-drop device that the utility model provides is simple in structure, cheap, and its brake component is active in one's movements, reliably.This anti-drop device also is applicable to other occasion, is specially adapted to install all kinds of elevators of braking guide rail.
