Description

Weight balance household elevator

Technical Field

The invention relates to a weight-balanced home elevator. The lifting movement is provided for the personnel by the aid of the effects of balance and unbalance of physical weight.

Background

The existing elevator is lifted by means of powerful electric power. Despite the counterweight, the weight of the car is at best offset. As for the lifting of personnel, the lifting is completed by doing work through electric power. Therefore, the energy consumption is extremely high, the structure is complex, and the manufacturing cost is expensive. Thereby affecting the popularization and the use in ordinary families and causing the inconvenience of life of the part of people.

Disclosure of Invention

Through adjusting to counter weight, all offset the weight behind the car manned, realize the weight balance at steel cable both ends. On the basis, the weight of the counterweight is slightly increased or decreased or the counterweight is directly interfered by external force, so that the balance is changed, the lift car is lifted, and people are delivered to required floors.

The technical scheme adopted by the invention for solving the technical problems is as follows: the car and counterweight are connected by a cable that passes over a fixed sheave to form a weight-dependent system. In this system, the car and the counterweight provide an upward lifting force to each other with their respective weights, counteracting the weight of each other. The counterweight is a container with counterweight. The counterweight can adjust the weight through input or output. For example, when we use water as the counterweight, a tank equipped with a submersible pump is provided in the counterweight container, and a tank equipped with a submersible pump is also provided on each floor of the counterweight path. When the cage stops at each floor, the water tank openings in the counterweight container are exactly opposite to the water tank openings of the related floors one by one. When using the elevator, after personnel got into the car, weight sensor will obtain the car poor with heavy weight to start the immersible pump in the relevant water tank and carry out work: if the lift car is heavier than the counterweight, the submersible pump of the floor water tank works to inject water into the counterweight water tank, so that the weight of the counterweight is increased. Otherwise, the submersible pump of the counterweight middle water tank works to discharge water to the floor water tank. Until the weight of the car and counterweight reach equilibrium. At this time, the floor lock of the car is unlocked, and the car and the counterweight are still in the original static state. This is the first step. Second, according to the occupant's instruction of the button while riding-is to go up? Or down? And starting the related submersible pump to work, and further reducing or increasing a starting base number for the water in the heavy water tank. The balance is changed as required, so that the two ends of the steel cable in the original static state move. Until the person is lifted to the desired floor. The floor lock is then locked and the person can walk out of the car. In practice the first and second steps may be carried out simultaneously, directly to bring the counterweight to the weight required for "equilibrium +" or "equilibrium-". Of course, after the balance between the car and the counterweight is realized in the first step, the balance is changed by external force, and the effect is the same.

The beneficial effects of the invention are that the practice and theory of physics tell us that: for a system in which the weight of the two ends of the steel cable is balanced, the original balance can be obviously changed by applying a force which is one tenth or even one tenth of the weight of the load, and is called as a starting base number. The system overcomes inertia and corresponding resistance, and the two ends of the steel cable are lifted and lowered. This eliminates the need for powerful power to do work. The method is simple, the power requirement is low, the energy consumption is low, the structure is simple, and the maintenance is convenient. Meanwhile, the taking and the storage of the heavy objects are realized on all corresponding floors, the potential energy of the heavy objects is not lost, and the energy consumption is further reduced. Because of the simplicity, reliability is also improved. The household can be made and used. The invention has low efficiency, but is simple, reliable, energy-saving and low-price, and is suitable for families.

Detailed Description

A fixed pulley (05) is mounted on a building member (02) at the top of the hoistway (01), and a steel cable (04) is connected with the car (03) and the counterweight container (06) across the fixed pulley (05). A counterweight water tank (07) is arranged in the counterweight container (06), the opening of the counterweight water tank (07) faces to the outer side, a submersible pump (08) is installed in the counterweight water tank (07), and the water outlet of the submersible pump (08) is arranged along the opening of the counterweight water tank (07).

The floor water tanks (09) are installed on all floors, and the openings of the floor water tanks (09) face to the opening side of the counterweight water tank (07) and are just opposite to each other. The submersible pump (08) in the floor water tank (09) is arranged along the opening of the floor water tank (09). Thus, when the submersible pump (08) in the heavy water tank (07) works, water in the heavy water tank (07) is injected into the floor water tank (09). Similarly, when the submersible pump (08) in the floor water tank (09) works, water in the floor water tank (09) is injected into the counter-weight water tank (07).

Therefore, the water quantity in the counterweight water tank (07) can be conveniently adjusted, so that the weight of the counterweight water tank (07) and the weight of the car (03) are balanced or slightly insufficient or slightly over. Thus, the car (03) is allowed to stand still, or to descend, or to ascend.

The water tanks (09) of all floors are provided with overflow pipes (10) and water replenishing pipes (11), and the water tanks are adjusted when the water level is too high or too low, so that the water tanks (09) of all floors can be filled with water into the counterweight water tank (07) at any time.

When the car (03) reaches the destination floor, the car (03) is locked at the floor by using a well-known floor lock device, so that the car is convenient for people to safely leave. So as to prevent accidents caused by dragging of the cage (03) by the counterweight container (06) after the weight of the cage is reduced.

Fig. 2 is another embodiment of the present invention, which does not require any external energy, and can lift the carrier by the arm power of the carrier, and the carrier can be assisted by external personnel when the arm power of the carrier is insufficient. Generally, the utility model is limited to be used by one person or one adult and one infant.

The functions of the hoistway (21), the building construction member (22), the car (23), the steel cable (24), the fixed pulley (25), the counterweight container (26) and the like are the same as those of the previous embodiment, and are not described again. The weight of the counterweight container (26) is set according to the maximum hoisting value of the car (23) and is fixed. It is set by referring to the person with the largest weight in the family, namely, when the person takes the car, the counterweight just enables the system to be balanced. When other people carry the vehicle, an additional object is additionally carried. The total weight of other persons and additives is equal to that of the heaviest person. Thus, the weight balance between the cage (23) and the counterweight container (26) can be ensured no matter who enters the cage (23). The following is a description with specific reference numerals. If the elevator is used, the person with the largest weight weighs 75kg, and the elevator is allowed to enter the car (23). At this time, the weight of the counter weight (27) is adjusted so that the weight of the counter weight container (26) and the weight of the car (23) are balanced. Thereby, the weight (27) is locked and is not changed. Then, if 60kg of people take the elevator, 15kg of accessories on the belt are added, and the weight balance can be achieved similarly. And so on.

The climbing rods (29) are a row of gripping rods firmly attached to the wall of the hoistway (21) and accessible to the arms of the passengers of the car (23) and able to climb or push. The pulling rope (28) is a soft rope connecting the bottom of the car (23) and the bottom of the counterweight container (26). Under the gravity balance state, the car (23) can be easily lifted and lowered by a person in the car (23) acting a climbing rod (29) upwards or downwards or pulling a traction rope (28) by an external person.

When the destination floor is reached, the annular floor lock (30) is firstly pulled to lock the car (23), and the person can only leave.

Fig. 3 is a front view and a left side view of the annular layer lock (30). The annular layer lock is composed of a lock shell with a semi-annular groove and a semi-annular strip-shaped bolt and is used in pairs. In the figure, 31. lock body, 32. annular groove, 35. cover plate, from which the lock shell part is formed. 33. Annular tongue 34 handle, which constitutes the tongue part. Because of the symmetrical pattern, the lock housing is drawn in simplified half, the upper half of the figure. The bolt portion is also drawn in half, in simplified form, as the lower half of the drawing. By pulling the handle (34), the annular lock tongue (33) can rotate along the annular groove (32) in an arc shape.

Fig. 4 is an operation diagram of the annular layer lock (30). Two identical annular layer locks (30) are placed opposite each other and are mounted on the building element (22) and on the car (23), respectively. For the sake of clarity of the representation of the operating situation, the right-hand annular layer lock (30) only outlines the lock housing part and the bolt part with dashed lines. When in use, the two annular layer locks (30) are required to be positioned at the same height and on the same longitudinal plane. At the moment, the two annular grooves (32) are just connected into a whole circle. If a handle (34) of the annular layer lock (30) is pulled, the two annular lock tongues (33) can act simultaneously, wherein the left annular lock tongue (33) can be inserted into the right annular groove (32), and meanwhile, the right annular lock tongue (33) is pushed to insert the other end of the right annular lock tongue into the left annular groove (32). The simultaneous locking of the double annular bolts (33) is realized. The locking of the car (23) to the desired floor is effectively achieved. For safety, a pair of annular layer locks (30) are required to be arranged at the diagonal positions of the car (23). And after the locking, passengers can get in and out of the car (23).

If the handle (34) is pulled back, the two annular lock tongues (33) respectively return to the original positions and are unlocked. Another advantage of the annular layer lock (30) is that it can be operated both to lock and unlock the car (23).

The annular layer lock (30), the climbing rod (29) and the pulling rope (28) can also be used in the former embodiment to play a role in case of sudden power failure.
