Embodiment Construction
[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0034] Such as figure 1 As shown, the traction rope 1 of the elevator is wound on the traction sheave 2, the car 3 and the counterweight 4 are respectively connected to the two ends of the traction rope 1, and a There are buffers 5. combine Figure 6 , 7 , 8, the weighing device 8 for weighing the weight of the elevator car 3 and the counterweight 4 in a preferred embodiment of the present invention includes a rope clamping device 6, a jacking device 7, and a weighing device 8.
[0035] The rope clamping device 6 is arranged on the traction sheave 2 to clamp and fix the traction rope 1 wound on the traction sheave 2 on the traction sheave 2; the jacking device 7 is arranged on the car 3 or the counterweight 4 Below,...

The invention relates to a weighing device for weighing the weight of a lift car and a counter weight. A hoisting rope is wound on a traction sheave. The lift car and the counter weight are connected to the two ends of the hoisting rope correspondingly. The weighing device comprises a rope clamping unit, a jacking unit and a weighing unit, wherein the rope clamping unit is arranged on the traction sheave and used for tightly clamping and fixing the hoisting rope wound on the traction sheave to the traction sheave; the jacking unit is arranged under the lift car or the counter weight so as to support the lift car or the counter weight, so that the corresponding connected hoisting rope is loosened; and the weighing unit is arranged on the jacking unit to measure the weight of the lift car or the counter weight. The rope clamping unit enables the traction sheave and the hoisting rope to be relatively fixed and not to slide, the jacking unit supports the lift car or the counter weight so as to enable the lift car or the counter weight to press the weighing unit independently, the weight of the lift car and the counter weight is obtained as a basic parameter of a lift, and accordingly whether the applicable load of buffers and safety tongs is within the parameter range required in a type-test certificate is judged.
Description
technical field [0001] The invention relates to the field of elevator detection, in particular to a weighing device for weighing the weight of an elevator car and a counterweight. Background technique [0002] refer to figure 1 As shown, whether the applicable weight of the buffer 5 and safety gear of each elevator corresponds to the actual car 3 and counterweight 4, and whether it is within the parameter range covered by the type test certificate is difficult to judge on site. [0003] At present, there are basically no weight parameters of the empty car 3 and counterweight 4 in the random documents of domestic elevators. There are also on-site factors such as decoration weight adjustments during the elevator installation process. The weight parameters of the elevator car and counterweight are unknown. Safety gear The selection of safety components such as buffer 5 is basically determined based on the empirical value of the weight of the empty car 3 and the counterweight 4...
