Description
Technical Field
[0001] The utility model relates to the technical field of elevator equipment, and more specifically, to an adjustable counterweight side bracket assembly for an elevator. Background Art
[0002] Elevators are indispensable equipment in modern buildings. The installation and fixation of elevators are extremely important for the safe and stable operation of elevators. Most elevators are equipped with counterweights. The existing installation positions of counterweights on elevators are divided into side-mounted and rear-mounted. Generally, the rear-mounted counterweight is for a machine-room passenger elevator, but in special cases, the counterweight can also be side-mounted. Generally, the side-mounted counterweight is for a machine-roomless passenger elevator, an observation elevator, a freight elevator, or a medical elevator. Since the size between the hoistway wall and the elevator car changes according to the size during the hoistway civil engineering, the elevator car and the hoistway wall are fixed through the cooperation of the car guide rail and the guide rail bracket. Then, when the counterweight is side-mounted and in a limited space, it is necessary to install both the counterweight guide rail of the counterweight and the car guide rail of the elevator car well, and to meet the requirements of installation convenience, good strength, and convenience in avoiding obstacles. All of the above problems need to be solved urgently.
[0003] Although there are many types of existing side-mounted counterweight brackets, 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 bracket and correct the dimensional deviation that occurs during the installation process through the structural design of the existing side-mounted counterweight bracket.
[0004] In summary, the existing elevator counterweight side bracket has the technical problem that the connection structure with the well wall is fixed strongly and it is difficult to adapt to the shape change of the elevator well wall. Content of the Utility Model
[0005] The technical problem to be solved by the utility model is that the existing elevator counterweight side bracket has the technical problem that the connection structure with the well wall is fixed strongly and it is difficult to adapt to the shape change of the elevator well wall.
[0006] To solve the above problems, the utility model provides an adjustable counterweight side bracket assembly for an elevator, which includes two horizontal bracket assemblies arranged in 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 horizontal bracket assemblies. The horizontal bracket assembly includes a cross beam for installing the elevator car guide rail and side brackets respectively fixedly connected to both ends of the cross beam. The side bracket includes a wall surface fixing part and a guide rail installation part in a right-angled shape, which are respectively used for connecting with the elevator well wall and the side counterweight guide rail on the corresponding side. The guide rail installation part includes a first rod and a second rod that are parallel to each other and telescopically connected. The end of the first rod is fixedly connected to the cross beam, and the end of the second rod is connected to the wall surface fixing part. The distance between the main counterweight guide rail and the elevator well wall is adjusted through the telescopic movement between the first rod and the second rod.
[0007] The semi-frame structure of the adjustable counterweight side bracket assembly provided by the utility model improves the connection mode between the counterweight guide rail and the elevator shaft wall. The connection mode of connecting the entire guide rail of the general bracket to the elevator shaft wall over a large area is improved to a multi-point connection and cooperation between multiple wall surface fixing parts and the elevator shaft wall, so that it is easier to adapt to the concave and convex shape of the elevator shaft wall. In addition, further, the guide rail installation part adopts a structure in which two rods are telescopically connected. Through this structure, the distance between the counterweight guide rail and the elevator shaft wall can be adjusted adaptively, so that it is easier to adapt to the local shape and different size changes of the elevator shaft wall, effectively solving the technical problem that the existing counterweight side bracket of the elevator has a strong fixed connection structure with the shaft wall and is difficult to adapt to the shape change of the elevator shaft wall.
[0008] As a preferred solution, one side surfaces of the first rod and the second rod are attached to each other, and positioning long holes are provided on the attached side surfaces of both. The length direction of the positioning long hole on the first rod is parallel to the length direction of the first rod, and the length direction of the positioning long hole on the second rod is perpendicular to the length direction of the second rod. By installing a pin structure in the positioning long holes on the first rod and the second rod respectively, the first rod and the second rod are fixed to fix the distance between the main counterweight guide rail and the elevator shaft wall.
[0009] This design provides a preferred cooperation mode between the first rod and the second rod. One side of the two is attached, and positioning long holes with perpendicular directions are provided on the attached side surfaces of each. Since the long axis directions of the positioning long holes on the two rods are perpendicular to each other, after the pin is installed, the relative positions of the two rods can be completely fixed, so as to realize the position fixing after the telescopic adjustment of the first rod and the second rod, improving the practicability of the bracket. The pin structure can specifically adopt a bolt and nut or other pin types that are convenient for tightening and fixing.
[0010] As a preferred solution, one end of the wall surface fixing part is integrally connected with one end of the second rod to form an L-shaped bracket, and the positioning long hole is provided on the top surface of the second rod and is connected to the bottom surface of the first rod through a pin structure. This design provides a preferred bracket structure. The second rod is fixedly integrated with the end of the wall surface fixing part to form an L-shaped structure. In addition, the first rod and the second rod are fixedly connected by surface attachment and auxiliary pins.
[0011] As a preferred solution, both the first rod and the second rod are C-shaped channel steel beams. The second rod is inserted into the groove of the first rod, and the middle of the wall fixing part is vertically and fixedly connected to the end of the second rod to form a T-shaped bracket structure. This design provides another bracket structure different from the above design. Both the first rod and the second rod are C-shaped channel steel beams. The notch diameter of the first rod is larger than the outer diameter of the second rod. The end of the second rod is inserted into the notch of the first rod. This design has a better positioning effect between the rods compared to the above design. The middle of the wall fixing part is integrally fixed with the end of the second rod to form a T-shaped bracket structure, which has good support stability and improves the strength of the bracket. As an extension of the above technical solution idea, it is optional to set positioning long holes on both the upper and lower side surfaces of the first rod and the second rod. Compared with the design of setting positioning long holes on only one side surface in contact, it has stronger positioning ability and the structure is more stable after installation.
[0012] As a preferred solution, the second rod is provided with a socket structure on the side surface of the end where it is connected to the first rod. The first rod is provided with a mounting hole on the side surface that fits with the socket structure. The mounting hole is used to mount a guide pin, and the guide pin is used for sliding and guiding cooperation with the socket structure. This design is based on the structure of the above two rods inserted into each other. A socket structure is set at the end of the second rod, and a mounting hole is set on the corresponding side surface of the first rod. The mounting hole is used to mount a guide pin. Through the cooperation of the guide pin and the socket structure, a guiding limit can be formed between the two rods, improving the stability of the connection between the two rods.

The cross beam uses a common C-shaped channel steel, and integral flanging structures are added to both edges. Through this structure, the bending and torsional resistance of the steel beam are 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, further improving the strength of the steel beam.
[0014] As a preferred solution, the cross beam and the main counterweight guide rail are adjustably connected through a right-angle mounting member. One side plate surface of the right-angle mounting member is fixedly attached to the top surface of the cross beam, and the other side plate surface is fixedly attached to the mounting side surface of the main counterweight guide rail through mounting holes in cooperation with fastening fasteners. This design optimizes the connection method between the cross beam and the main counterweight guide rail. The right-angle mounting member is an angle steel section. One side is fixedly attached to the top side surface of the cross beam, preferably by welding. The other side of the right-angle mounting member is attached to the fixed side of the main counterweight guide rail. It can be welded or can be connected to the guide rail member by setting mounting holes in the right-angle mounting member and cooperating with fastening fasteners. Such a method can conveniently adjust the position of the main counterweight guide rail.

The end faces at both ends of the flanging structure of the cross beam are welded to the outer side plate surface of the first rod, and the end face of the first rod is inserted into the C-shaped groove of the cross beam and welded. This design further optimizes the structural design of the side bracket guide rail mounting part. Using a C-shaped channel steel beam, it has good structural strength, low cost and is convenient for obtaining materials. On the basis of this structure, to improve the structural strength of the connection point between the guide rail mounting part and the cross beam, the end of the guide rail mounting part is inserted into the C-shaped groove at the end of the side of the cross beam and welded and fixed. In addition, similarly, the guide rail mounting part is provided with mounting holes in cooperation with fastening fasteners to connect the side counterweight guide rail, which is convenient for adjusting the positions between the guide rail and the bracket relative to each other.
[0016] As a preferred solution, the wall fixing part is provided with two wall fixing holes at a preset distance from each other on the side for fitting the elevator shaft wall. The wall fixing holes are in the shape of waist-shaped holes, which are used to provide a margin for position adjustment of the wall fixing part.

Two waist-shaped holes are provided on the plate surface side where the wall fixing part fits the wall surface. The two waist-shaped holes can be set perpendicular to each other or at a certain inclination angle, and good adjustment performance can be obtained, which is convenient for fine-tuning the position between the bracket and the shaft wall.
