Guide rail lifting platform: A brief introduction to the production method of a guide rail lifting platform

Guided rail lifting platform The current construction safety elevator uses a double-twisted steel wire rope for safety. The controller controls the hydraulic cylinder to extend by pressing the set emergency button, slowing the falling speed until it stops by pressing the friction block onto the friction belt. The spring buffers the impact during friction, improves stability, and protects equipment components. Although this device can achieve the effect of preventing falling, its controller sends a signal to control the movement of the hydraulic cylinder. The method used is to press a button to make the hydraulic cylinder push the friction block into contact with the friction strip to achieve the effect of deceleration. However, after the elevator steel wire rope breaks, it will fall at a faster speed, and the user may fall to the ground before they react. During the elevator's descent, the user is in a state of weightlessness, and it cannot be guaranteed that the button will be pressed immediately, and there will be a certain delay when the hydraulic cylinder needs to pump oil during operation. Therefore, the technical solution of this device cannot guarantee that the elevator will lock immediately in a state of zero gravity.

Technical personnel provide a guided rail lifting platform to solve the problems mentioned in the above background technology. To achieve the above purpose, the Guided rail lifting platform The following technical solutions are adopted: A guided rail lifting platform, including a slider, guide rail, frame, steel wire rope, lifting mechanism, steel wire rope self-locking mechanism, and lifting platform. The four guide rails are respectively set at the four corners of the frame, and the four corners of the lifting platform are respectively fixedly connected with the slider. The slider cooperates with the guide rail and forms a moving pair in the guide rail. Four cable self-locking mechanisms are respectively set on the guide rail. The cable self-locking mechanism includes a weight, belt, pulley, transmission plate, and cable clamp. The pulley is rotatably mounted on the top of the guide rail; one end of the cable is wound around the pulley and fixedly connected with the slider, and the other end is fitted on the winding pulley in the lifting mechanism; a screw is provided at the end of the pulley; one end of the belt is connected to the slider, and the other end is hung with a weight; two cable clamps are relatively set on the guide rail and face the cable, wherein one cable clamp is fixedly installed on the guide rail via a bolt, and the other cable clamp is installed in the mounting hole of the guide rail and can move along the mounting hole; the transmission plate is rotatably installed on the side of the pulley; the transmission plate is fixedly connected with the cable clamp which is movably installed on the guide rail. A connecting bracket is provided on the side of the slider, the connecting bracket passes through the back of the guide rail, and one end of the weightless belt is fixedly connected with the connecting bracket. A circular mounting groove is provided on the side of the pulley, and a circular guide block at the end of the transmission plate cooperates with the circular mounting groove. The lifting mechanism includes a small gear, a motor, a winding wheel, a rotating shaft, a large gear, a wedge block, and a hydraulic cylinder. The rotating shaft is installed on the frame through an integral bearing frame; the large gear is fixedly fitted on the rotating shaft, and two winding wheels are respectively fixedly fitted on the two ends of the rotating shaft; the motor is fixedly installed on the frame, and a small gear is fixedly fitted on the power output end of the motor, and the large gear meshes with the small gear.

Compared with the existing technology, the above Guided rail lifting platform The beneficial effects are: Through the threaded connection relationship between the pulleys, during the rapid descent of the slider due to the breakage of the steel wire rope, a speed difference is generated between the pulleys, so that the pulley can move inward, and the steel wire rope clamp can clamp the steel wire rope to prevent the slider from continuing to fall, thereby preventing the lifting platform from self-locking and falling, and ensuring safe use.
