Abstract
The utility model discloses a friction elevator, comprising a frictional drum, a driving device, a lifting table, falling weights, and steel cables. The driving device and the frictional drum are all fixed on the lifting table. The frictional drum is two revolving bodies which are thin in the middle part and thick at both ends and the two revolving bodies are bound by two steel cables respectively. The upper ends of the steel cables are connected with a stable equilibrium device and the lower ends of the steel cables are provided with the falling weights. The utility model has the advantages of compact structure, little space occupation and convenient operation. The friction elevator is particularly suitable for the installation of the elevator rails and the internal construction of the height buildings.
Description
The utility model is a kind of lifting jacking system.
Existing lifting jacking system, include winding type, friction-type, creeping-type etc., wherein friction-type (as Fig. 1) is with friction drum (1-2), actuating device (1-1) is installed on the higher fixed platform, steel rope (1-3) is walked around friction drum (1-2), and an end of its steel cable is connected with falling weight, and the other end (1-4) links to each other with bay-lift (being cage).When rotating under the driving of friction drum (1-2) at actuating device, under the effect of friction force between friction drum (1-2) and the steel rope (1-3), bay-lift can rise or descend.Thereby reach the purpose of lifting lifting.The shortcoming of this device is the control system complexity, the operator can not operate in bay-lift, and also difficulty etc. is installed, especially in especially big lifting elevation scope (as above 300 meters, even reach 500 meters) when other work such as elevator rail is installed, just be unsuitable for adopting this device.
The purpose of this utility model is, change the installation site of friction drum and actuating device, make it can be with the bay-lift up-and-down movement, thereby the difficulty when having solved in elevation scope operation and problem such as inconvenience is installed, make the operator on bay-lift, control dipping and heaving voluntarily, satisfied construction requirement greatly.
The utility model is to realize like this, a kind of friction-type jacking system is by friction drum, actuating device, bay-lift, falling weight and steel rope are formed, and it is characterized in that actuating device and friction drum all are fixed on the bay-lift, friction drum is the pluckings gyro-rotors in two centres thin two, and link to each other with fixing balancing device around, the upper end of this steel rope by two wire rope rolls that are parallel to each other respectively, its lower end is connected with falling weight.Principle of work of the present utility model is: 1, and when bay-lift will rise, actuating device drove the friction drum rotation, and this reel is twining steel rope and is rising, and at this moment the above steel cable of friction drum shortens gradually, and following steel rope is elongated gradually.2, when bay-lift will descend, actuating device drove friction drum to opposite spin, and this friction drum is twining steel cable and descending, and at this moment the following steel rope of friction drum shortens, and above steel rope is elongated.3, when bay-lift will be parked in a certain position, actuating device quits work, friction drum also just stops the rotation, because the effect of falling weight and the following steel rope weight of friction drum, and steel rope twines multi-turn and produces the effect of friction force greatly on the friction drum, makes this device in whole motion process, reach equilibrium of forces, thereby can reach above-mentioned three kinds of athletic performances.
The utility model has the advantages that the operator can control lifting voluntarily on bay-lift; Actuating device, friction drum and bay-lift are installed can carry out on ground etc.This device be particularly useful in the higher buildings and television transmitting tower in the installation of especially big elevation elevator rail and inner structure etc.Advantages such as this device also has compact conformation, and floor area is little.
Below in conjunction with the embodiment explanation.
Fig. 1: existing friction-type jacking system figure.
Fig. 2: the utility model jacking system figure.
Fig. 3: friction drum series connection figure.
Fig. 4: friction drum figure in parallel.
In order to guarantee this device normal operation, reliable running, make its design more reasonable, two friction drums (4) shaped design of this device is middle thin two pluckings gyro-rotors, to guarantee that steel rope around friction drum the time, has regularity, be unlikely to around unrest, steel rope can be twined in the restricted portion on friction drum, thereby dwindle the occupation of land space of friction drum.
See Fig. 3 and 4, the installation of friction drum can be adopted dual mode, and a kind of is that two friction drums are connected mutually and are one, and a kind of is parallel with one another.Its two kinds of effects are the same, just can determine installation form according to the size of working space.
Concrete structure of the present utility model as shown in Figure 2, one steel rope hangs on the fixing equalizer pulley (5), two steel ropes (2) that hang down are wrapped in respectively on two friction drums (4) regularly, friction drum (4) links to each other with jacking system (1), the two is all fixed with bay-lift, two lower ends of steel cable (2) are connected with two falling weights (3) respectively, the one falling weight is installed in the vertical channel of another falling weight, two falling weights can only be slided up and down mutually, that can not rotate mutually separates, can not self rotation, avoiding the mutual winding of steel cable, thereby guarantee this device reliability during operation.
In addition, described equalizer pulley (5) also can be replaced by balancing drum, is wrapped on the balancing drum respectively with two steel cables, and is fixed on above it, and other structure is the same.This structure can increase the reliability of this device.
Claims (5)
1, a kind of friction-type jacking system, be by friction drum, actuating device, bay-lift, falling weight and steel rope are formed, and it is characterized in that: actuating device (1) and friction drum (4) all are fixed on the bay-lift (6), friction drum is the pluckings gyro-rotors in two centres thin two, and reeling by two steel ropes that are parallel to each other (2) respectively, the upper end of this steel rope (2) links to each other with the balancing device of fixing (5), and its lower end is connected with falling weight (3).
2, jacking system according to claim 1 is characterized in that: described two friction drums (4) can be gone here and there mutually and are connected as a whole.
3, jacking system according to claim 1 is characterized in that: described two friction drums (4) are for parallel with one another.
4, jacking system according to claim 1 is characterized in that: described balancing device (5) can be equalizer pulley.
