Description

Technical Field

[0001] The utility model relates to the field of elevator car frames, in particular to a lifting elevator car frame. Background Art

[0002] An elevator is a vertical transportation device, usually composed of a motor, guide rails, wire ropes and control systems. Its main function is to conveniently transport people or goods vertically inside a building or large facility. Driven by a motor, the elevator can run up and down along the guide rails and is equipped with safety devices to ensure the safety of passengers. Elevators are widely used in residential buildings, commercial buildings, hospitals, subway stations and other places, providing convenience for people's lives and work. The elevator bridge frame is an important part of the elevator system and is usually made of steel structure. It is located at the top of the elevator shaft and is used to support the guide rails and traction system of the elevator. The main function of the bridge frame is to provide a stable support platform so that the various components of the elevator can operate safely and smoothly.

[0003] The prior art (publication number: CN 217867603 U) discloses a simple elevator car frame, comprising a main upper beam, a main lower beam and two main vertical beams, the main upper beam, the main lower beam and the two main vertical beams are fixedly connected to form a rectangular main frame, the main upper beam and the main lower beam are arranged in parallel up and down, and the front and rear of the main frame are respectively provided with parallel arranged sub-frames, the main vertical beam is provided with a sub-cross beam fixed to the upper end of the sub-frame, and the main lower beam is provided with a car floor fixed to the lower end of the sub-frame; a pull rod is fixed between the main vertical beam and the car floor, and the main vertical beam, the car floor and the pull rod form a triangular structure; the car floor is provided with an upper floor and a lower floor, and a supporting grid structure is provided between the upper floor and the lower floor.

[0004] Although the above patent adopts a main frame and two sub-frames to form a three-dimensional frame structure, which greatly improves the overall rigidity of the car frame, and uses a pull rod to further pull the car floor, so that the force on the entire car frame is more uniform, it has the following disadvantages. When in use, the size of the main upper and lower beams cannot be adjusted. When it is necessary to carry and fix elevator cars of different widths, it is inconvenient to match and fix them, resulting in the inability to place elevators of different widths, thereby reducing the practicality of the elevator car frame. The scope of application is low and further improvement is needed. For this reason, we propose a lifting elevator car frame. Utility Model Content

[0005] The main purpose of the utility model is to provide a lift car frame, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The elevator car frame includes a convex block, two of which are arranged and distributed up and down, a rotating component is installed on the right ends of the two convex blocks, two groups of crossbeam components symmetrically distributed front and back are installed on the two convex blocks, rectangular grooves are formed at the upper ends of the two convex blocks, and adjustment components are arranged in the two rectangular grooves. The front and rear ends of the adjustment components are fixedly connected to two adjacent crossbeam components, the front and rear crossbeam components are symmetrically distributed front and back, and two vertical rods are installed between the two upper crossbeam components and the two lower crossbeam components.

[0008] Preferably, the adjusting component includes forward and reverse threaded rods, which are arranged between the left inner wall and the right inner wall of the rectangular groove. The outer surface threaded sleeves of the forward and reverse threaded rods are provided with two movable plates symmetrically distributed on the left and right. Two fixed blocks are installed at the ends of the two movable plates away from each other. The four fixed blocks are all provided with a first screw. The lower wall of the movable plate is in movably contact with the inner wall of the rectangular groove.

[0009] Preferably, the rotating component includes a bearing seat, two of which are provided and distributed front and back, a rotatable worm is provided between the two bearing seats, the worm is meshingly connected with a worm wheel, the front end of the worm moves through the front end of the front bearing seat and is fixedly connected to a second screw, a nut is threadedly sleeved on the outer surface of the second screw, and the rear end of the worm moves through the rear end of the rear bearing seat and is fixedly connected to a knob.

[0010] Preferably, the right end of the forward and reverse threaded rod movably passes through the right end of the convex block and is fixedly connected to the left end of the worm gear.

[0011] Preferably, the crossbeam component comprises a fixing seat, the fixing seat is mounted on the convex block, a guide plate is mounted on the upper end of the fixing seat, and two cross bars symmetrically distributed on the left and right are movably sleeved on the outer surface of the guide plate.

[0012] Preferably, a support plate is commonly installed at the upper ends of the two front and rear cross bars on the lower side, a connecting rod is commonly installed between the support plate and the vertical rod, and a plurality of bolts are arranged on the vertical rod, and the bolts extend to the cross bar.

[0013] Preferably, the front end and the rear end of the convex block both begin to have through grooves, the fixed block is located in the through grooves, and the left and right cross bars are fixedly connected to the left and right fixed blocks respectively.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The distance between the cross bars can be adjusted by setting the adjustment component. When a wider elevator car needs to be installed, the forward and reverse threaded rods are rotated, and the forward and reverse threaded rods drive the two movable plates to move away from each other. The two movable plates drive the left and right sets of cross bars to move away from each other through the fixed blocks, so that the size of the car frame becomes wider, and the wider elevator car can be fixed, thereby improving the practicality and application range of the elevator car frame;

[0016] 2. The adjusting parts can be adjusted quickly and conveniently by rotating the parts. When in use, turning the knob drives the worm to rotate, the worm drives the worm wheel to rotate, and the worm wheel drives the positive and negative threaded rods to rotate. The worm gear transmission can usually achieve a larger transmission ratio and can provide a larger torque output to a certain extent, thereby realizing labor-saving transmission to a certain extent, facilitating the staff to make quick adjustments, reducing the burden on workers to a certain extent, reducing the force required for workers to operate the equipment, and making their work easier and more comfortable.

[0027] The distance between the cross bars 51 can be adjusted by the adjusting component 9, which is convenient for fixing the elevator car with a wider size. The specific structure is: the adjusting component 9 includes a positive and negative threaded rod 91, and the positive and negative threaded rod 91 is arranged between the left inner wall and the right inner wall of the rectangular groove 7. The outer surface of the positive and negative threaded rod 91 is threadedly sleeved with two movable plates 92 symmetrically distributed on the left and right. Two fixed blocks 93 are installed at one end of the two movable plates 92 away from each other. The four fixed blocks 93 are all provided with a first screw 94. The lower wall of the movable plate 92 is in active contact with the inner wall of the rectangular groove 7.

[0028] In order to reduce the force required by workers when operating the equipment and make their work easier and more comfortable, the forward and reverse threaded rods 91 are driven to rotate by the rotating component 10, and the specific structure is as follows: the rotating component 10 includes a bearing seat 102, and two bearing seats 102 are provided and distributed front and back. A rotatable worm 106 is commonly provided between the two bearing seats 102, and the worm 106 is meshingly connected with a worm wheel 101, and the worm 106 and the worm wheel 101 are self-locking. The front end of the worm 106 moves through the front end of the front bearing seat 102 and is fixedly connected to the second screw 103. The outer surface of the second screw 103 is threadedly sleeved with a nut 104.
