Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and more specifically, to a freight elevator car with a secondary guide shoe connection structure. Background Art

[0002] A freight elevator is a large-scale electromechanical device integrating machinery and electronics. A guide shoe is a slidable nylon block between the elevator guide rail and the car, called a guide shoe. It can fix the car on the guide rail and allow the car to only move up and down. There is also an oil cup on the upper part of the guide shoe to reduce the friction between the shoe lining and the guide rail.

[0003] Freight elevators are widely used in places such as factories, hotels, and shopping malls that need to transport goods. Currently, freight elevators usually use two guide rails for installation and operation. Although this method has a simple structure and is convenient for installation and use, when the weight of the goods carried by the freight elevator is placed on one side, the car will be eccentrically loaded and tilt to one side, forming a seesaw situation. This will reduce the contact area between the guide rail and the guide shoe, increase the contact force, exacerbate the wear of the guide shoe, and shorten its service life. Therefore, it is difficult for the car frame with two guide rails to ensure the normal operation of the elevator. Therefore, the existing technology has problems such as poor running stability of the freight elevator, serious wear of components, short service life of components, and high operating costs. In view of the above problems, a solution is proposed below. Summary of the Utility Model

[0023] Embodiment 1:

[0024] See also Figure 1-4 A freight elevator car 1 with a secondary guide shoe 6 connection structure includes a freight elevator car 1, and main beams 2 are symmetrically and fixedly connected in the middle of both sides of the freight elevator car 1. The main beams 2 are made of I-shaped steel. H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight, so as to ensure force, and the main beams 2 are arranged symmetrically in the middle of the freight elevator car 1 to ensure that the entire freight elevator car 1 is balanced and stable, and avoid tilting due to the gravity of the freight elevator car 1 itself.

[0025] The top and bottom of the two main beams 2 are fixedly connected with main crossbeams 3 respectively, and each main crossbeam 3 is symmetrically installed with a main boot 4, that is, the main crossbeam 3 located at the upper part of the freight elevator car 1 and the main crossbeam 3 located at the lower part of the freight elevator car 1 are respectively installed with two main boots 4, and the four main boots 4 are arranged in a rectangular row. The four main boots 4 can ensure the stability of the freight elevator car 1 during the up and down movement.

[0026] At both ends of the freight elevator car 1, there are receiving rings 5 sleeved. The symmetric receiving rings 5 can ensure the stable force on both ends of the freight elevator car 1. The receiving rings 5 are fixedly connected to the freight elevator car 1, thus ensuring the stable position of the receiving rings 5 and the freight elevator car 1, avoiding the shaking caused by movement, increasing safety. The receiving ring 5 includes a cross bar 14 and a vertical bar 15. There are two cross bars 14, and the two cross bars 14 are respectively arranged on the upper and lower sides of the freight elevator car 1. There are two vertical bars 15, and the two vertical bars 15 are respectively arranged on the front and rear sides of the freight elevator car 1, and the two vertical bars 15 are located between the two cross bars 14. The mutually remote sides of the two vertical bars 15 and the two end faces of the two cross bars 14 are in the same plane. The two ends of the two vertical bars 15 are respectively fixedly connected to the two ends of the two cross bars 14. The two cross bars 14 and the two vertical bars 15 form a rectangle. By connecting the two cross bars 14 through the two vertical bars 15, the two cross bars 14 are made into a whole, increasing the force on the two cross bars 14 in the vertical direction. At the same time, it can increase the separation force resistance of the two cross bars 14 in the horizontal direction from the freight elevator car 1, thus ensuring stability. At the connection of the cross bar 14 and the vertical bar 15, there is a straight plate-shaped connection block 16. The contact parts of the straight plate-shaped connection block 16 with the cross bar 14 and the vertical bar 15 are fixedly connected by welding. The straight plate-shaped connection block 16 can increase the contact area between the cross bar 14 and the vertical bar 15, thus playing the role of increasing the stability of the connection stability.

[0027] The inner side of the receiving ring 5 is in contact with the outer side of the freight elevator car 1. On the upper and lower end faces of the freight elevator car 1, there are a number of auxiliary guide shoes 6. The number of auxiliary guide shoes 6 are respectively installed on the cross bars 14 of the two receiving rings 5, and two auxiliary guide shoes 6 are respectively installed on each cross bar 14. The auxiliary guide shoes 6 on each receiving ring 5 are located inside the same plane. The main guide shoe 4 plays a role in ensuring the stability during the overall movement. The number of auxiliary guide shoes 6 on the symmetrically arranged receiving rings 5 plays a role in ensuring the stability of both ends of the freight elevator car 1, thus reducing the pressure generated on the main guide shoe 4 due to the inclination of the freight elevator car 1 caused by the unbalanced force inside the freight elevator car 1, that is, ensuring the stable and smooth up and down movement of the freight elevator car 1.

[0028] The receiving ring 5 and the main beam 2 are fixedly connected through a fixed connecting member 7. The fixed connecting member 7 includes a connecting rod 8 and a connecting frame 9. The connecting frame 9 is installed in the middle of the side of the main beam 2. There are two connecting rods 8. One ends of the two connecting rods 8 are installed on the connecting frame 9 by welding. The other ends of the two connecting rods 8 are respectively fixedly connected to one ends of the corresponding vertical rods 15 by welding. The two connecting rods 8 are symmetrically arranged. The vertical rods 15, the two connecting rods 8 and the connecting frame 9 form an isosceles trapezoid structure. The connecting rod 13 can increase the tensile force on the receiving ring 5, improve the supporting force of the receiving ring 5 on both ends of the freight elevator car 1, thereby further preventing the freight elevator car 1 from tilting, and at the same time reducing the pressure on the auxiliary guide shoe 6, ensuring the overall movement stability. At the same time, the connecting rod 13 can fix the position of the receiving ring 5, increase the connection force between the receiving ring 5 and the freight elevator car 1, ensure stability and increase safety.

[0029] Embodiment 2:

[0030] Please refer to Figure 5 , a freight elevator car 1 with an auxiliary guide shoe 6 connection structure. Different from Embodiment 1, the fixing component includes a receiving rod 10 and a tension rod 11. There are two receiving rods 10, and the two receiving rods 10 are symmetrically arranged up and down. The two receiving rods 10 can connect the receiving ring 5 and the main beam 2, and at the same time ensure the positions of the receiving rod 10 and the freight elevator car 1. The two receiving rods 10 are located between the receiving ring 5 and the main beam 2. The two ends of the two receiving rods 10 are respectively fixedly connected to the receiving ring 5 and the main beam 2. There are two tension rods 11, and the two tension rods 11 are cross-arranged. The two tension rods 11 are located between the two receiving rods 10. The two ends of the two tension rods 11 are respectively fixedly connected to the corresponding ends of the receiving rod 10. The cross-fixed tension rods 11 can increase the force between the two receiving rods 10.

[0031] Embodiment 3:

[0032] Please refer to Figure 6 , a freight elevator car 1 with an auxiliary guide shoe 6 connection structure. Different from Embodiment 1, the fixing component includes a mounting frame 12 and a connecting rod 13. There are two mounting frames 12, and the two mounting frames 12 are respectively fixedly connected to the opposite sides of the receiving ring 5 and the main beam 2. There are several connecting rods 13, and the several connecting rods 13 are respectively located between the two mounting frames 12. The two ends of the several connecting rods 13 are respectively fixedly connected to the two mounting frames 12. The connecting rod 13 and the mounting frame 12 are fixedly connected at a non-right angle. The inclined design can increase the supporting force and ensure stability. And the adjacent two connecting rods 13 are symmetrically arranged up and down.

[0033] Working principle:

[0034] Connect the main guide shoes 4 through the main crossbeam 3. Multiple main guide shoes 4 above and below ensure stable connection. Connect the auxiliary guide shoes 6 through the bearing ring 5. Multiple auxiliary guide shoes 6 have a stabilizing effect on the main guide shoes 4, avoiding problems such as tilting caused by unbalanced force. Moreover, the design that the bearing ring 5 fits closely with the four sides of the freight elevator car 1 can ensure the force on the freight elevator car 1, avoiding damage to the freight elevator car 1 caused by excessive single-sided force on the freight elevator car 1. And the fixed connecting piece 7 can further ensure the connection of the bearing ring 5. At the same time, it can disperse the force of the bearing ring 5 on the freight elevator car 1 to the main beam 2, further reducing the force on the freight elevator car 1, thereby further ensuring the stability of the freight elevator car 1 and further reducing tilting.
