Description

Technical Field

[0001] This invention relates to the field of elevator load-bearing, and particularly to an elevator load-bearing device and an elevator. Background Technology

[0002] Currently, the load-bearing beams of elevator load-bearing devices are generally made of structural steel. The structure involves pre-drilling holes in the shaft wall for the load-bearing beams, installing the structural steel beams within these holes, and ensuring the steel beams penetrate the shaft. This type of elevator load-bearing device has the following disadvantages:

[0003] 1. It is necessary to increase the reserved holes for load-bearing beams, which places high demands on civil engineering.

[0004] 2. Because the load-bearing steel beam needs to pass through the shaft, it requires a lot of materials, which is not conducive to saving costs.

[0005] 3. Because the load-bearing steel beam needs to pass through the shaft, it is easy for the elevator door operator and the load-bearing steel beam to overlap in the vertical projection. In order to avoid interference, the top floor height required in the elevator design is relatively high.

[0006] 4. Because the load-bearing steel beam needs to pass through the shaft, the counterweight end rope head needs to be installed with cantilever support, which can easily cause the load-bearing components to sway.

[0007] 5. The shock-absorbing rubber in the existing elevator load-bearing device is subjected to inconsistent stress, resulting in inconsistent deformation at the front and rear, causing the traction machine to tilt. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an elevator load-bearing device that is stable under force and effectively prevents the traction machine from tilting.

[0009] The technical problem to be solved by the present invention is to provide an elevator equipped with the elevator load-bearing device.

[0010] To solve the above-mentioned technical problems, the present invention provides an elevator load-bearing device, including a load-bearing component, a traction machine and a shock-absorbing component. The load-bearing component includes a support beam, a support member, a guide rail and a guide rail support plate. The support member is respectively disposed at both ends of the support beam and fixedly connected to the support beam. The guide rail support plate is fixedly installed on the side wall of the support beam and fixedly connected to the guide rail.

[0011] The traction machine, the shock absorption assembly, and the support beam are fixedly connected in sequence. The shock absorption assembly includes an adjusting plate, an adjusting component, and a shock absorption pad. The shock absorption pad is disposed between the adjusting plate and the support beam. The adjusting component is disposed on the adjusting plate and can be movably connected to the support beam to adjust the distance between the adjusting plate and the support beam.

[0012] As an improvement to the above solution, the support beam is a hollow structure with an opening on one side. The support beam includes an upper support plate and a lower support plate, and the guide rail support plate is disposed in the opening and fixedly connected to the upper support plate and the lower support plate respectively.

[0013] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0014] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0015] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0016] The pair of counterweight rope head groups are fixedly installed on the counterweight rope head plate and pass through the notch.

[0017] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0018] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0020] As the improvement of the above-mentioned scheme, the pair of counterweight rope head groups are fixedly installed and hung on the supporting beam, and the center lines of the pair of counterweight rope head groups and the axis of the supporting beam are connected perpendicularly.

[0021] Correspondingly, the application also provides an elevator provided with the elevator load bearing device.

[0022] The application has the following advantages:

[0023] The supporting beam of the elevator load bearing device is fixed on the wall of the shaft through the supporting pieces at both ends, and the guide rail support plates and the guide rails of the side wall jointly act on the supporting beam, so that the whole supporting beam forms a three-point force supporting plane. Compared with the two-point supporting force of the traditional load bearing beam penetrating the shaft, the supporting beam of the application is not inclined and does not shake after being stressed, and is stable in stress. At the same time, there is no need to reserve a load bearing beam hole on the wall of the shaft, which reduces the requirements for civil construction and also reduces the amount of steel used, thereby saving costs. The problem of vertical projection overlap interference between the supporting beam and the car door machine is also avoided, so that a larger door opening width can be designed for the same shaft width.

[0024] In addition, the distance between the adjusting plate and the supporting beam can be adjusted by the movable connection of the adjusting plate and the supporting beam, that is, the tightening or loosening of the adjusting plate is realized, so that the overall deformation of the shock pad between the adjusting plate and the supporting beam is consistent, and the traction machine is prevented from tilting due to inconsistent overall deformation of the shock pad.

[0028] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application in the text are based on the drawings of the present application, and are not specific limitations on the present application.

[0029] Referring to Figures 1-3 , the present application discloses an elevator load-bearing device, which comprises a load-bearing assembly, a traction machine 5 and a shock-absorbing assembly, the load-bearing assembly comprises a supporting beam 1, a supporting piece 2, a guide rail 3 and a guide rail support plate 4, the supporting piece 2 is respectively arranged at both ends of the supporting beam 1 and is fixedly connected with the supporting beam 1, and the guide rail support plate 4 is fixedly installed on the side wall of the supporting beam 1 and is fixedly connected with the guide rail 3.

[0030] The traction machine 5, the shock-absorbing assembly and the supporting beam 1 are sequentially fixedly connected; the shock-absorbing assembly comprises an adjusting plate 6, an adjusting piece 7 and a shock-absorbing pad 8, the shock-absorbing pad 8 is arranged between the adjusting plate 6 and the supporting beam 1, and the adjusting piece 7 is arranged on the adjusting plate 6 and can be movably connected with the supporting beam 1, so as to adjust the distance between the adjusting plate 6 and the supporting beam 1.

[0031] The supporting beam of the elevator load-bearing device of the present application is fixed on the wall of the shaft through the supporting pieces at both ends, and the guide rail support plate and the guide rail on the side wall jointly act, so that the supporting beam as a whole forms a three-point force support plane. Compared with the two-point support force of the traditional load-bearing beam penetrating through the shaft, the supporting beam of the present application does not tilt or shake after being subjected to force, and is stable in force. At the same time, there is no need to reserve a load-bearing beam hole on the wall of the shaft, which reduces the requirements on the civil engineering, reduces the amount of steel used and saves the cost. In addition, the problem of vertical projection overlap interference between the supporting beam and the car door machine is avoided, so that a larger door opening width can be designed for the same shaft width.

[0032] Furthermore, the present invention can adjust the distance between the adjusting plate and the support beam by movably connecting the adjusting plate and the support beam, thereby tightening or loosening the adjusting plate, so that the overall deformation of the damping pad between the adjusting plate and the support beam is consistent, preventing the traction machine from tilting due to inconsistent overall deformation of the damping pad.

[0033] It should be noted that the adjusting component 7 is a bolt, and the adjusting component 7 is threadedly connected to the support beam 1. There are two adjusting components 7, one on each side. By adjusting the two adjusting components, the deformation of the shock-absorbing pad on both sides can be made uniform, so that the left and right sides are level, thereby preventing the traction machine from tilting.

[0034] The support member 2 is L-shaped. It is also equipped with a supporting rib 21. The support member is fixed to the shaft wall by a fastening assembly, and the support member and the support beam are fixedly connected by the fastening assembly.

[0035] Specifically, such as Figure 1 , 3 As shown, the support beam 1 is a hollow structure with an opening on one side. The support beam 1 includes an upper support plate 1a and a lower support plate 1b. The guide rail support plate 4 is disposed within the opening and is fixedly connected to the upper support plate 1a and the lower support plate 1b respectively. Preferably, the guide rail support plate 4 is welded to the upper support plate 1a and the lower support plate 1b respectively. In addition to connecting with the guide rail, the guide rail support plate also strengthens the support beam, making the support beam structure robust and stable under stress.

[0036] Furthermore, such as Figures 1-3 As shown, the present invention also includes a counterweight rope head assembly 9, which is fixedly installed and suspended on the support beam 1, and the centerline of the counterweight rope head assembly 9 is perpendicularly connected to the axis of the support beam 1. The counterweight rope head assembly is directly installed on the support beam, preventing the wire rope from interfering with the support beam. Furthermore, the centerline of the counterweight rope head assembly is perpendicularly connected to the axis of the support beam, meaning the counterweight rope head assembly is positioned at the center of the support beam. Compared to existing cantilever supports, this provides greater stability under stress, ensuring the support beam is balanced and does not sway.

[0037] Preferably, such as Figure 1 , 3 As shown, the present invention also includes a counterweight support plate 10 corresponding to the counterweight rope head assembly 9. The counterweight support plate 10 is disposed within the opening and is fixedly connected to the upper support plate 1a and the lower support plate 1b, respectively. Specifically, the counterweight support plate 10 is welded to the upper support plate 1a and the lower support plate 1b, respectively. The counterweight support plate strengthens the support beam on which the counterweight rope head assembly is installed, making the support beam structure robust and stable under stress.

[0038] Furthermore, such as Figures 1-3As shown, the application further comprises a supporting assembly, which comprises a counterweight rope head plate 11 and a counterweight support plate 12, the counterweight rope head plate 11 is erected above the support beam 1 through the counterweight support plate 12, the upper supporting plate 1a and the lower supporting plate 1b are both provided with a notch 1c corresponding to the counterweight rope head plate 11; the counterweight rope head group 9 is fixedly installed on the counterweight rope head plate 11 and passes through the notch 1c. The setting of the supporting assembly can make the installation position of the counterweight rope head group higher, save the counterweight stroke, and facilitate the design and arrangement of the elevator. At the same time, in order to avoid the overlapping interference of the steel wire rope and the support beam, the counterweight rope head group is provided with a notch at the vertical projection position of the support beam, that is, the vertical projection position corresponding to the upper supporting plate and the lower supporting plate, so as to ensure that the support beam does not interfere with the steel wire rope, and the counterweight rope head group remains suspended on the support beam, thereby ensuring that the support beam is balanced and stable in force.

[0039] Preferably, as shown in Figure 1 、 3 The supporting assembly further comprises a reinforcing rib 13 arranged on the counterweight support plate 12. The setting of the reinforcing rib further increases the strength of the supporting assembly.

[0040] Preferably, as shown in Figure 1 、 3 The application further comprises an anti-inclination assembly, which comprises a fixed plate 14, the fixed plate 14 is fixedly connected with the guide rail 3 and the top of the traction machine 5 respectively. The traction machine is connected with the guide rail through the fixed plate, and the guide rail prevents the traction machine from inclining forward due to uneven force.

[0041] More preferably, as shown in Figures 2-3 The anti-inclination assembly further comprises a damping pad 15 arranged on the fixed plate 14, and the damping pad 15, the fixed plate 14 and the traction machine 5 are fixedly connected. The setting of the damping pad plays a role of shock absorption.

[0042] Preferably, as shown in Figure 1 、 3 The traction machine 5, the shock absorption assembly and the guide rail support plate 4 are arranged in sequence from top to bottom. That is, the traction machine 5, the shock absorption assembly and the guide rail support plate 4 are arranged in sequence in the longitudinal direction. Since the guide rail support plate is fixedly connected with the guide rail, it can well support the traction machine and the shock absorption assembly, thereby ensuring the firmness of the overall structure of the elevator load bearing device.

[0043] Correspondingly, the application further discloses an elevator, which is provided with the elevator load bearing device. The specific structure of the elevator load bearing device is as described above, and will not be described here again.

[0044] In summary, the application provides an elevator load bearing device and an elevator, which are stable in force and effectively prevent the inclination of the traction machine.
