Description

Technical Field

[0001] The utility model relates to a component or device specially suitable for an elevator, in particular to a simple inclined bracing bar structure of an elevator car. Background Art

[0002] The elevator is a common vertical transportation tool. It is driven by a traction machine and rises and falls along the guide rails fixed vertically in the elevator shaft to transport passengers or goods to different floors quickly and safely. Among them, the elevator car frame is an important part of the elevator, which plays the role of supporting and protecting the car. It mainly includes the car top for providing protection and support from above, the car wall for separating the interior of the car from the shaft, the car bottom for carrying passengers and goods, the columns for connecting the car top and the car bottom, the crossbars for cooperating with the columns to improve the stability of the car, and the reinforcing ribs distributed between the corresponding components to increase the structural strength. The existing elevator car structure usually uses vertical tie bars (reinforcement ribs) to enhance the strength and rigidity of the car. However, this structure often has the following problems: the number of vertical tie bars is large, which not only increases the weight and cost of the car; and due to the inherent design structure of the tie bar structure design and layout, it cannot simultaneously meet the requirements of lightweight, high strength and high balance of the car. Utility Model Content

[0003] The purpose of the utility model is to provide a simple elevator car inclined bracing structure, which fundamentally solves the above-mentioned problems and has the advantages of flexible arrangement, convenient processing and installation, and can improve the overall stability of the elevator.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the simple elevator car inclined brace structure comprises a car bracket, a car floor laid on the car bracket, a pair of car columns fixed on the outside of the car bracket and perpendicular to the plane where the car floor is located, and a pair of C-shaped lower cross beams fixed back to back at the center of the bottom of the car bracket, and the technical key points are: the end of the lower cross beam is fixed on the outside of the car column, a triangular inclined brace is arranged between the car column and the car bracket, and a guide wheel bracket is fixed between the lower cross beam and the inclined brace and located at the bottom of the car bracket, the inclined brace comprises a main board fixed to the outside of the car bracket by a bolt assembly, and flanges arranged on two right-angled sides of the triangle perpendicular to the main board, one of the flanges is fixed to the car column by bolts, and the car brackets and car columns on both sides are respectively provided with protruding structures, and a diagonal tie rod is hingedly fixed between the two protruding structures on the corresponding sides, and the diagonal tie rod and the diagonal tie rod are arranged on both sides of the car column.

[0005] Beneficial effects of the utility model:

[0006] In terms of the overall technical solution, the car bracket is connected to the car column by oblique tension bars. Under the premise of not affecting the installation of the side control panel, the uneven mass distribution in the car, or the torque generated on the elevator car frame during acceleration or deceleration of the elevator is transmitted to the steel structure composed of the car column, the lower crossbeam, and the car bracket, thereby avoiding the problem of forward and backward shaking of the car caused by eccentric loading in the depth direction.

[0007] In terms of specific structure, the car column and car bracket are used as the basic structure, a pair of lower cross beams are fixed in the middle of the bottom of the car bracket, and the ends of the lower cross beams are fixed on both sides of the car column as the main supporting structure. On one side of the car column and the car bracket, a diagonal tie bar is set to limit the swing of the car column; on the other side, a diagonal tie rod is hinged between the car column and the car bracket to limit the swing of the car column. By setting an asymmetric anti-eccentric load structure on the front and rear sides of the car column, the torque is evenly applied to the frame structure of the entire elevator car, thereby effectively improving its stability.

[0008] In summary, the utility model has the advantages of flexible layout, convenient processing and installation, and ability to improve the overall stability of the elevator. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following combination Figure 1~2, the specific contents of the utility model are described in detail through specific embodiments. The simple elevator car inclined brace structure includes a car bracket 5, a car floor 6 laid on the car bracket 5, a pair of car columns 1 fixed on the outside of the car bracket 5 and perpendicular to the plane where the car floor 6 is located, and a pair of C-shaped lower crossbeams 2 fixed back to back at the bottom center of the car bracket 5. Among them, the end of the lower crossbeam 2 is fixed on the outside of the car column 1, a triangular inclined brace 4 is provided between the car column 1 and the car bracket 5, and a guide wheel bracket 3 is fixed between the lower crossbeam 2 and the inclined brace 4 and located at the bottom of the car bracket 5. The inclined brace 4 includes a main plate 41 fixed to the outside of the car bracket 5 by two M12 bolt assemblies 7 (bolts, nuts, spring washers), and flanges 42 arranged on two right-angled sides of the triangle perpendicular to the main plate 41, and the length of the side fixed to the car bracket 5 is greater than the side fixed to the car column 1. As a preferred embodiment, the connecting hole (not shown in the figure) on the inclined tie bar 4 is a waist-shaped hole to facilitate fine adjustment. The inclined tie bar 4 can stabilize the car bracket 5. The thickness of the flange 42 matches the car column 1 and does not exceed the outer edge of the car, so as not to affect the installation and use of other structures or components. One of the short flanges 42 is fixed to the car column 1 by bolts. The car bracket 5 and the car column 1 on both sides are respectively provided with a protruding structure. A diagonal tie rod 8 is hingedly fixed between the two protruding structures on the corresponding sides. The inclined tie bar 4 and the diagonal tie rod 8 are respectively arranged on both sides of the car column 1. By connecting the car column (1) and the car bracket (5) to hinge the inclined tie rod (8), a stable triangular structure is formed, thereby effectively enhancing the structural stability and safety of the elevator car and effectively avoiding the shaking and deformation of the car during operation. When installing the inclined tie rod (8), the size, load, running speed, etc. of the car are comprehensively considered to ensure that it can withstand the force and torque generated by the car under different working conditions. The inclined tie bars (4) transmit the deformation torque of the car to the steel structure composed of the car columns (1), the lower cross beam (2), and the car bracket (5) by means of prestressed pulling, so that the car as a whole can still remain stable when the elevator is accelerating or decelerating, or when the car floor (6) in the car generates torque due to uneven force.

[0012] Furthermore, the elevator car generally has a certain distance in the depth direction, and the gantry system that bears its load is a frame, so a structure is needed to balance it in the depth direction, that is, the diagonal tie bar 4. The diagonal tie bar 4 is a round steel or flat steel diagonally arranged. In this way, the diagonal tie bar 4 cannot be used in some shallow cars or when there are other mechanisms on the side of the car, such as a control panel, thereby effectively avoiding the problem of unbalanced car. By setting the diagonal tie bar 4, the number of vertical tie bars is effectively reduced, the overall quality and cost of the car are reduced, and the installation is more convenient and quick. At the same time, the strength and stiffness distribution of the car are made more uniform, thereby effectively improving the safety and stability of the car. Used in conjunction with the car bracket 5 and the lower crossbeam 2, the bracket load is effectively balanced, avoiding the tipping of the car due to the uneven load in the depth direction, and cleverly solving the shortcomings of the traditional slender diagonal tie bar 4 that the space occupied is difficult to arrange. The overall layout of the elevator is more convenient and smart, the position of the control panel can be arranged more freely, and there is no need to consider the situation that the inclined tie bars 4 cannot be arranged due to the thickness of the control panel, which makes the elevator stability poor. It also has more advantages in processing and installation.

[0013] In addition, the inclined tie bars 4 can replace part of the traditional structure, thereby reducing the number of vertical tie bars in the car, reducing the deadweight of the car, and helping to increase the load. By unevenly installing the inclined tie bars 4 and the inclined tie rods 8 on both sides of the car column 1, it helps to improve the stability and anti-torque deformation ability of the car during operation, and effectively increases the structural stability of the car. Moreover, compared with the existing vertical structure, the installation of the inclined tie bar 4 structure is more compact and will not occupy too much space inside the car, which helps to improve the space utilization of the car.
