Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a novel embedded counterweight frame for elevators. Background Art

[0002] At present, the counterweight frame adopts independent guide shoe limit guide. When the counterweight guide shoe falls off, the counterweight frame will be separated from the guide rail and an accident will occur. The counterweight block currently adopts an integral form, which causes the counterweight frame to either reserve a large space on the top for placing the counterweight block, wasting space; or the straight beam is punched out, causing stress concentration and weakening of the straight beam strength; when the traction rope is used, the side length is deformed by tension, resulting in uneven force on the traction rope, which can easily cause the traction rope to exceed the breaking force. Summary of the invention

[0003] Based on the technical problem that the existing integral counterweight of an elevator easily causes uneven force on the traction rope, which results in the traction rope exceeding the breaking force, the present invention proposes a novel embedded counterweight frame for an elevator.

[0004] The present invention proposes a new type of elevator embedded counterweight frame, comprising a counterweight frame body, a counterweight block is slidably inserted into the inner side wall of the counterweight frame, and the counterweight block located on the top of the counterweight frame body is divided into two parts and spliced ​​together, and then locked by a locking mechanism located on the upper surface of the counterweight block;

[0005] The outer surfaces of both sides of the counterweight frame are provided with guide and limit structures, and the guide and limit structures are used to install the counterweight frame on the guide rails in the elevator to achieve guidance and limit;

[0006] A pressure sensing balance device is fixedly installed on the top of the counterweight frame, and the pressure sensing balance device includes a pressure sensor and a traction rope. The pressure sensor monitors and senses the tension on the surface of each traction rope, and then the data detected by the pressure sensor is transmitted to the elevator control center for balance analysis;

[0007] A height detection device is fixedly installed on the lower surface of the counterweight frame, and the height detection device monitors the vertical height of the lower surface of the counterweight frame from the bottom wall of the elevator shaft in real time, and the data is then transmitted to the elevator control center for balance analysis.

[0008] Preferably, the locking structure comprises two symmetrically distributed support frames, and inner walls of opposite ends of the two support frames are slidably sleeved with support rods.

[0009] Preferably, both ends of the support rod are threadedly connected with locking bolts, and the opposite ends of the two locking bolts are screwed in to support the two support frames outward at both ends, and the opposite ends of the two support frames are respectively extended vertically to the inner walls of both sides of the counterweight frame and locked.

[0010] Preferably, the guide limiting structure comprises a guide groove and a block-type limiting structure or a wheel-type limiting structure, and the guide groove is provided on both side outer surfaces of the counterweight frame.

[0011] Preferably, the block-type limiting structure comprises a U-shaped block, and four of the U-shaped blocks are respectively fixedly mounted on the inner walls at both ends of the two guide grooves.

[0012] Preferably, the wheel-type limiting structure comprises limiting wheels, and the limiting wheels are fixedly mounted on the inner walls at both ends of the guide groove through pins.

[0013] Preferably, the pressure sensing balancing device also includes a sensing bracket and a guide wheel structure, the pressure sensor is fixedly mounted on the surface of the sensing bracket, the guide wheel structure includes a support shaft, and the pressure detection end of the pressure sensor detects the pressure on the surface of the support shaft.

[0016] Preferably, the height detection device comprises a mounting plate, the upper surface of the mounting plate is fixedly connected to the middle portion of the lower surface of the counterweight frame, and a height sensor is fixedly mounted on the lower surface of the mounting plate.

[0017] The beneficial effects of the present invention are:

[0018] 1. The counterweight block located at the top of the counterweight frame is divided into two parts and then locked by a locking mechanism located on the upper surface of the counterweight block, thereby achieving the effect of further making full use of the top of the ordinary counterweight frame which cannot be fully utilized due to the length limitation of the counterweight block. After the counterweight blocks are spliced, the locking mechanism is used to position and lock them.

[0019] 2. By setting up a guide and limiting structure, compared with the prior art in which the steel wire rope can only be slidably connected with the four corners of the counterweight frame, the guide and limiting structure can not only increase the contact area between the traction rope and the counterweight frame, but also play a limiting role.

[0020] 3. By setting up a pressure sensing balancing device, the tension on each traction rope can be monitored in real time. Each data is monitored by the pressure sensor and transmitted to the elevator control system for comparison.
