Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, and particularly relates to an elevator counterweight side support device. Background Technique

[0002] An elevator is an indispensable device in modern buildings. The installation and fixation of an elevator are extremely important for the safe and stable operation of the elevator. Most elevators are equipped with a counterweight. The existing installation positions of the counterweight on the elevator are divided into side-mounted and rear-mounted. Generally, the counterweight is rear-mounted for passenger elevators in machine rooms, but in special cases, the counterweight can also be side-mounted. Generally, the side-mounted counterweight is for machine-roomless passenger elevators, sightseeing elevators, freight elevators, and medical elevators. Since the size between the hoistway wall and the elevator car changes according to the size during the hoistway civil engineering, the elevator car is fixed to the hoistway wall through the cooperation of the car guide rail and the guide rail support. Then, when the counterweight is side-mounted and in a limited space, it is necessary to install the counterweight guide rail of the counterweight and the car guide rail of the elevator car well, and to meet the requirements of convenient installation, good strength, and convenient obstacle avoidance. All the above problems need to be solved urgently.

[0003] Although there are many types of existing side-mounted counterweight supports, during the actual installation process, due to the flatness of the hoistway wall and small errors during the installation process, it is very difficult to adjust the horizontal flatness of the side-mounted counterweight support and correct the dimensional deviation that occurs during the installation process through the structural design of the existing side-mounted counterweight support. To adapt to the offset of the well wall shape, a variety of auxiliary connecting pieces are set, but limited by the assembly cost of the actual frame structure, if non-standard parts of various different shapes are used for auxiliary installation, it will cause a substantial increase in the cost of the elevator counterweight support, which is not conducive to the large-scale application of the support structure.

[0004] In summary, the existing elevator counterweight side support has technical problems such as complex support structure and high cost. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is that the existing elevator counterweight side support has technical problems such as complex support structure and high cost.

[0006] To solve the above problems, the present utility model provides an elevator counterweight side support device, which includes two horizontally arranged support assemblies that are parallel and spaced apart by a preset distance. Two side counterweight guide rails and a main counterweight guide rail are respectively connected between the two horizontally arranged support assemblies. The horizontally arranged support assembly includes a cross beam for installing an elevator car guide rail and side supports respectively fixedly connected to both ends of the cross beam. The side support includes a wall surface fixing part and a guide rail installation beam that are connected at a right angle, and are respectively used to connect with the elevator shaft wall and the side counterweight guide rail on the corresponding side. The wall surface fixing part is a right-angle mounting plate. One side plate surface of the right-angle mounting plate is attached to the elevator shaft wall for installation, and the other side plate surface of the right-angle mounting plate is supported and connected to the end of the guide rail installation beam. A right-angle mounting plate is also connected to the middle of the cross beam, and both side plate surfaces of the right-angle mounting plate are respectively attached to the top surface of the cross beam and the side surface of the main counterweight guide rail for fixation.

[0007] The novel elevator counterweight side support device provided by the present utility model improves the connection method between the counterweight guide rail and the elevator shaft wall through a semi-frame type support structure, and improves the connection method of connecting the entire guide rail of the general support to the elevator shaft wall in a large area to a multi-point connection and cooperation between multiple wall surface fixing parts and the elevator shaft wall, so as to be more adaptable to the concave and convex shape of the elevator shaft wall. In addition, to avoid the increase in the support cost caused by the complexity of the support structure, the connection part structures between the wall surface fixing part, the cross beam and the main counterweight guide rail are unified, and all adopt the right-angle mounting plate structure with the same structure. The right-angle mounting plate structure ensures good support performance through its own right-angle structure and can adapt to various right-angle connection surfaces. This design simplifies the materials used in the support structure, reduces the use of non-standard parts, and effectively solves the technical problems of the existing elevator counterweight side support, such as complex support structure and high cost.

[0008] As a preferred solution, the cross beam is a C-shaped channel steel beam, and flanging structures that bend inward are arranged on both the upper and lower sides of the middle area of the cross beam. A reinforcing cross plate is fixedly connected between the flanging structures of the cross beam. This design further optimizes the structural design of the cross beam in the horizontally arranged support assembly. The cross beam adopts a common C-shaped channel steel, and integral flanging structures are added to the edges on both sides. Through this structure, the bending and torsional strength of the steel beam is further increased. On this basis, a reinforcing cross plate along the length direction of the cross beam is welded and fixed in the middle section of the flanging structure of the cross beam to further improve the strength of the steel beam.

[0009] As a preferred solution, the right-angle mounting plates connected to the end of the guide rail installation beam and the right-angle mounting plates connected to the cross beam and the main counterweight guide rail are both provided with raised reinforcing rib structures at the central axis position of the plate surface. The structural strength of the plate surface of the right-angle mounting plate structure in the above design is further enhanced. By arranging an integral raised reinforcing rib structure at the central axis position of the plate surface of the right-angle mounting plate, it is equivalent to increasing the thickness of its plate surface, effectively improving the anti-deformation strength of the right-angle mounting plate.

[0010] As a preferred solution, the right-angle mounting plates are provided with flanging reinforcing ribs on both side edges of the plate surface. This design further optimizes on the basis of the above strengthening structure by also providing integral flanging reinforcing ribs on both side edges of the right-angle mounting plates, similarly enhancing the anti-deformation and anti-torsion performance of the right-angle mounting plates.

[0011] As a preferred solution, paired distribution mounting holes are provided on the side surfaces of the right-angle mounting plates and the guide rail mounting beams located between the cross beam and the main counterweight guide rail. The spacing between the mounting holes on the right-angle mounting plates matches the width of the main counterweight guide rail, and the spacing between the mounting holes on the guide rail mounting beams matches the width of the side counterweight guide rail. The mounting holes are used to assemble fasteners to clamp and fix the main counterweight guide rail or the side counterweight guide rail from the side.

[0012] This design optimizes the docking method between the bracket and the counterweight guide rail. Symmetrical mounting holes are provided at the docking position between the bracket structure and the guide rail. The spacing between the two mounting holes at the same position matches the side width of the guide rail. By assembling fasteners at the mounting hole positions, it can be conveniently connected to the counterweight guide rail, can be conveniently fastened to the guide rail, and can be easily loosened and adjusted through the fastener structure to adjust the connection position with the guide rail, improving the assembly flexibility.

[0013] As a preferred solution, the guide rail mounting beam is a C-shaped channel steel beam, and the end face of the guide rail mounting beam is inserted into the C-shaped groove of the cross beam and welded and fixed. This design optimizes the connection between the cross beam and the guide rail mounting beam. Both of them are C-shaped channel steel beams, and the diameter of the guide rail mounting beam is smaller. Therefore, the end can be vertically inserted into the groove of the cross beam and welded and fixed. This connection method has good fixing property and structural strength.

[0014] As a preferred solution, the right-angle mounting plate connected to the end of the guide rail mounting beam is provided with two wall surface fixing holes spaced a preset distance on the side surface for fitting the elevator shaft wall. The wall surface fixing holes are in the shape of waist-shaped holes, which are used to provide position adjustment allowance for the wall surface fixing part. This design optimizes the installation and cooperation method between the wall surface fixing part and the elevator shaft wall. Two waist-shaped holes are provided on the plate surface side where the wall surface fixing part is in contact with the wall surface. The two waist-shaped holes can be set to be perpendicular to each other or at a certain inclination angle, and good adjustment performance can be obtained, facilitating fine adjustment of the position between the bracket and the shaft wall.

[0015] As a preferred solution, a diagonal brace beam is connected between the wall surface fixing part and the guide rail mounting beam on the side away from the guide rail mounting beam, which is used to strengthen the bracket structure. In the above technical solution, the wall surface fixing part and the guide rail mounting part are at a right angle. To enhance the overall tensile, compressive and torsional performance of the bracket, a diagonal brace beam is added between the wall surface mounting part and the guide rail mounting beam. By this beam structure, a right triangle is formed, greatly improving the strength of the bracket.

[0016] As a preferred solution, a structurally reinforcing groove that is recessed inward is provided on the side surface of the cross beam, and the structurally reinforcing groove is parallel to the length direction of the cross beam. This design optimizes the overall structure of the cross beam body, and a groove structure is provided on the beam slab surface to enhance the structure of the beam body.
