Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

First, an embodiment of an anti-falling self-locking module of a lifter is provided, which comprises a clamping groove (not shown) and a first self-locking mechanism; as shown in fig. 1, the first self-locking mechanism includes a first lock lever 1, a swinging and traversing mechanism 2, a first mounting member 3, and a second mounting member 4; the first mounting piece 3 is fixedly arranged on the elevator driving belt 100 and is connected with the swinging and transversely moving mechanism 2; the lower end of the second mounting piece 4 is connected with the first mounting piece 3 through an elastic piece 5 and is fixedly connected with the elevator load part 200; the first lock rod 1 is connected with the first mounting part 3 through the swinging and traversing mechanism 2, and the elastic part 5 can release elastic potential energy when the transmission belt 100 breaks, drive the first mounting part 3 to move downwards relative to the second mounting part 4, drive the swinging and traversing mechanism 2 to swing and drive the first lock rod 1 to traverse in a direction close to the clamping groove. It is understood that the traversing includes horizontal movement and other movements having a displacement in a horizontal direction.

In order to achieve the anti-falling effect, other components connected with the lock rod cannot continuously fall after the lock rod is inserted into the clamping groove, so that the clamping groove is usually fixedly arranged, for example, on a fixed rack. In order to enable the lock rod to be inserted into the clamping groove in the continuous movement of the elevator, a plurality of clamping grooves are usually arranged in the working direction of the elevator.

When the elevator normally lifts, the gravity of the load part 200 acts on the upper end of the elastic member 5 through the second mounting member 4, the upward tension of the driving belt 100 acts on the lower end of the elastic member 5 through the first mounting member 3, and the elastic member 5 is compressed. When the transmission belt 100 breaks from the upper side, the first mounting part 3 is not pulled upwards by the transmission belt 100, so that an upward pressing force cannot be provided for the elastic part 5, the elastic part 5 is restored from a compressed state, the first mounting part 3 is pushed to move downwards relative to the second mounting part 4, the swinging and traversing mechanism 2 is driven to swing, and the first lock rod 1 is driven to move transversely in a direction approaching the clamping groove and is inserted into the clamping groove, so that anti-falling is realized.

In the prior art, for example, in a specific embodiment of the chinese patent cn202223201559.X, if a guide rail is used to convert a vertical motion into a lateral motion, or a tooth-shaped stop is used to perform guiding braking, extrusion and friction between metals can cause generation of metal flying chips, while the present application uses the swing of the swing and lateral movement mechanism 2 to guide, and uses a lock lever to perform blocking collision type braking, so as to reduce the metal flying chips as much as possible.

The manner of setting the swinging and traversing mechanism 2 is not limited, as long as it can swing by the downward movement of the first mounting member 3 and drive the first lock lever 1 to traverse. The oscillating traversing mechanism 2 is generally composed of a simple structure, is relatively low in manufacturing and maintenance costs, and is generally high in rigidity, can bear high loads, and is suitable for applications requiring high loads. In this embodiment, the swinging and traversing mechanism 2 is configured as a link mechanism, and includes a first link 21 fixedly connected to the first mounting member 3; and a second link 22 having one end hinged to the first link 21 and the other end hinged to the first lock lever 1. When the belt 100 breaks from above, the first link 21 moves downward with respect to the second mount 4 due to the fixed connection with the first mount 3, and the end of the second link 22 hinged to the first link 21 also moves downward so that the second link 22 swings, and a lateral movement occurs at the end of the second link 22 hinged to the first lock lever 1.

Considering that the first link 21 may be laterally moved due to the interaction when the first lock lever 1 is driven to laterally move, the related components may be moved, which is disadvantageous in keeping the load portion 200 stable, and the first link 21 is sleeved on the belt 100 in this embodiment, so that the belt 100 is used to receive part of the interaction.

The first mounting member 3 is not limited in arrangement, and may be fixedly connected to the driving belt 100, in this embodiment, as shown in fig. 2, the driving belt 100 is a synchronous belt with teeth on one side, the first mounting member 3 is configured as a base plate 31 and a mounting plate 32 that can be relatively fixed to the teeth carried by the synchronous belt, the base plate 31 is slidably sleeved on the driving belt 100, one end of the base plate is fixedly connected to the first connecting rod 21, and is provided with the elastic member 5, and the other end of the base plate is fixed to the driving belt 100 through the mounting plate 32. It will be appreciated that other connection arrangements for connecting the load carrying portion 200 to the timing belt may be provided, at least at a position below the first mounting member 3.

In view of the higher degree of freedom of the swinging and traversing mechanism 2, in this embodiment, a guiding portion 6 fixedly connected to the loading portion 200 is further provided, and a guiding channel is provided in the guiding portion 6, so that the first lock lever 1 can be guided in a set direction, so that the probability of inserting the first lock lever 1 into the card slot is improved.

In view of timely notifying an operator of the handling after the breakage of the driving belt 100, in this embodiment, a sensor 7, specifically, a photoelectric sensor, for detecting whether the driving belt 100 is broken is further provided, where the sensor 7 is used to send a signal to make other mechanisms of the elevator respond, for example, make the machine alarm, make other anti-falling mechanisms of the signal response operate, etc.

Considering that the clamping groove is usually fixed, and the movement process of the elevator is continuous, the position of the broken transmission belt 100 has a certain probability that the first lock rod 1 cannot be inserted into the clamping groove, and in the embodiment, a second self-locking mechanism is further provided, including: a cylinder 81 which receives the signal from the sensor 7 and extends the piston rod according to the signal; and a second lock lever 82 that is driven by the cylinder piston rod to move in a direction approaching the card slot. The second self-locking mechanism and the first self-locking mechanism are mutually backup, so that the falling probability of the load part 200 is further reduced.

An embodiment of the anti-falling elevator of the utility model comprises a transmission belt 100, a loading part 200 and the anti-falling self-locking module of the elevator.

In this embodiment, the load carrying portion 200 includes: the load carrying platform 201, and the frame 202 for connecting the load carrying platform 201 and the drive belt 100 and supporting the load carrying platform, the second mounting member 4 and the guide portion 6 are fixedly provided on the frame 202.

Considering that the working mode of inserting the lock rod into the clamping groove has a certain probability of failure, in this embodiment, the device comprises two driving belts 100, and further comprises a connecting portion 101, other than the anti-falling self-locking module of the elevator, for connecting the load-carrying portion 200 and each driving belt 100, wherein the first self-locking mechanism is arranged on each driving belt 100, and when one driving belt 100 fails, the other driving belt 100 can continue to provide tension and support for the load-carrying portion 200 through the connecting portion 101 and/or the anti-falling self-locking module.

By providing different anti-falling mechanisms of various operating principles, the anti-falling elevator embodiments have a relatively reliable prevention of personnel safety accidents, equipment or product damage caused by breakage of the elevator belt 100.

The above description may be implemented alone or in various combinations and these modifications are within the scope of the present utility model.
