Description

Technical Field

[0001] The invention relates to the field of elevator car frame upper beams, and in particular to an elevator car frame upper beam device and an elevator. Background Art

[0002] The existing elevator car frame has the following problems:

[0003] 1. The function of the upper beam is only to bear weight and its function is single.

[0004] 2. The upper beam is formed by bending a large piece of plate, which uses a lot of materials and has high cost.

[0005] 3. Elevator safety clamps are typically installed under the car floor or on the lower beam. However, placing the safety clamp under the car floor places high demands on the space below the car floor. This is especially true when the car floor wheels are arranged at an angle, which can easily cause the safety clamp to overlap and interfere with the car floor wheels. This is detrimental to the elevator design and may even require increasing the pit depth to accommodate this design. If the safety clamp fails to reset automatically, maintenance personnel may need to climb into the air to reset it, which is very dangerous.

[0006] 4. In order to adapt to elevators with and without machine rooms, it is often necessary to design a separate upper beam assembly to meet the needs of these two types of elevators. Different parts need to be produced, with a low commonality rate, resulting in high production costs.

[0007] 5. Existing safety clamps adjust the force using a torsion spring running through a linkage rod. The torque is adjusted by tightening a knob in the corresponding hole on the torque adjustment plate. This torque is the force required to release the safety clamp. During production assembly or on-site installation, at least two people are required to complete the adjustment. This adjustment method is difficult and labor-intensive.

[0008] 6. The existing lock ladder assembly is arranged in a front-to-back, left-to-right arrangement on the upper beam, while the left and right counterweights are positioned oppositely, resulting in an uncommon upper beam, a low universality rate, and high production costs. Summary of the Invention

[0017] As an improvement of the above solution, the adjustment assembly further includes an adjustment disk, which is sleeved outside the linkage rod and fixed relative to the linkage rod in the circumferential direction. The adjustment disk is provided with an adjustment hole, and the adjustment disk is connected to the elastic member through the adjustment hole.

[0018] As an improvement to the above solution, the first upper beam, the linkage support plate and the reinforcement plate are fixedly connected by a fastening assembly;

This also further reinforces the structure of the upper beam, increasing its strength. Maintenance personnel can conveniently and safely manually reset the safety clamp from the car roof, eliminating the risk of having to climb mid-air to reset the safety clamp.

It can be seen that whether it is a machine room elevator or a machine roomless elevator, the elevator car upper beam device of the present application can be adopted, the general rate of parts is effectively improved, so as to reduce the cost.

[0040] In addition, the elevator safety gear is arranged on the upper beam instead of being arranged under the car bottom or on the lower beam, so that the requirement for the pit depth is reduced. Moreover, the safety gear is arranged between the first upper beam body and the second upper beam body, so that the space is fully utilized, the top layer height of the car frame is not increased, the structure of the upper beam body is further reinforced, and the strength of the upper beam is increased. The maintenance personnel can conveniently and safely manually complete the reset operation of the safety gear on the car top, so that the risk that the maintenance personnel needs to climb to the air to reset the safety gear is avoided.

[0041] Further, as shown in Figure 4 , 6 , the safety gear mechanism further comprises a reinforcing plate 6 arranged between the first upper beam body 1 and the second upper beam body 2 and fixedly connected with the first upper beam body 1 and the second upper beam body 2 respectively, and the safety gear 5, the gear mounting plate 4 and the reinforcing plate 6 are fixedly connected. The arrangement of the reinforcing plate not only further strengthens the installation of the safety gear on the upper beam body, but also strengthens the connection structure of the first upper beam body and the second upper beam body, and increases the strength of the upper beam. The safety gear, the gear mounting plate and the reinforcing plate are fixedly connected, which not only can reinforce the safety gear, but also further strengthens the strength of the upper beam, so that the overall structure of the upper beam is more firm and reliable.

The loose joint group is arranged on the linkage support plate 8, and both ends of the elastic member 9 are connected with the linkage rod 7 and the loose joint group respectively, so that the elastic member 9 is elongated or shortened by driving the loose joint group. The elastic member 9 is preferably a spring. The user can elongate or relax the elastic member by driving the loose joint group, so as to elongate or shorten the elastic member, thereby achieving the purpose of linkage adjustment of the elastic force of the safety gear. The number of the linkage support plates 8 is two, which are arranged at both ends of the first upper beam body 1 respectively, and both ends of the linkage rod 7 are arranged on the two linkage support plates 8 respectively.

[0044] Specifically, as shown in Figure 6-7As shown, the joint group includes a joint 10 and an adjusting member 11. The elastic member 9 is connected to the joint 10. The joint 10 is passed through the linkage support plate 8 and is threadedly connected to the adjusting member 11. The joint 10 is driven by rotating the adjusting member 11 to extend or shorten the elastic member 9. The joint 10 is preferably a joint bolt, and the adjusting member 11 is preferably a butterfly nut. One end of the elastic member is hooked on the joint, and the joint 10 passes through the joint hole (not shown) on the linkage support plate 8 and is threadedly connected to the adjusting member 11. The user only needs to rotate the adjusting member with one hand to make the joint rise or fall, thereby extending or shortening the elastic member. Compared with the existing adjustment operation that requires two people to complete, the present invention only requires one person to complete the operation, and the adjustment is simple and convenient.

[0045] Preferably, the linkage support plate 8 is provided with a scale (not shown in the figure), which is used to indicate the tension corresponding to the stretched length of the elastic member, so that production or installation workers can quickly adjust the strength of the reset spring.

There are two bayonet 1a, and they are arranged along the axial direction of the first upper beam 1. When the ladder lock rod is in the locked or unlocked state, the hand lever can be locked into the bayonet at different positions of the first upper beam to secure the ladder lock rod.
