Description

Elevator weight sensor anti-drop device

Technical field

The utility model relates to a kind of improved counterweight housing of elevator, particularly a kind of fixing Elevator weight sensor anti-drop device to pouring weight of conveniently assemble and disassemble, adjustment that is suitable for counterweight housing of elevator.Belong to elevator and manufacture field engineering field.

Background technology

At present, counterweight housing of elevator has been manned or cargo lift very important balancing device in service.The pinch device of existing counterweight housing of elevator termination presser type during fabrication, need to be distinguished processing mounting holes mostly in two of a support body vertical beam, needs during fabrication to process 4-52 the pressing plate mounting hole not waiting, and compresses pouring weight so that be bolted pressing plate.This not only loses time in the time producing, and has additionally increased productive costs.In addition, some counterweight housing of elevator products use the mode of brace pressing plate to be fixed, and part dimension used is larger, and inconvenience is installed.The elevator also having uses the mode of tying up, with steel band by all pouring weight is banded together, to reach fixing object, complicated operation when the method makes on-the-spot installation, labour intensity is large.Above-mentioned fixed form has all increased work capacity to on-the-spot fitting operation person, does not play the effect reducing costs simultaneously.

According to patent documentation report, be in " to the pouring weight securing device " of CN202346559U at patent announcement number, record pouring weight adapter plate has been installed on the through hole of counterweight straight beam by bolt, and the structure screwing with nut.Binding bolt is installed on pouring weight adapter plate, and binding bolt main application is to compress pouring weight, to prevent that counterweight piece is in support body displacement in service, and the noise producing while reducing Elevator weight sensor operation.Though reach the object of fixing counterweight, but still have bolt penetration hole inconvenience, adjust difficult problem.Take the channel steel type straight beam in counterweight frame (also referred to as vertical beam or column) as example, the quantity that needs the hole of punching processing is the structure of 22 to 26, if the porose no longer processing of institute, a counterweight support body can be saved about 12 minutes.Through the conversion of work time standard, can calculate savable fund." elevator counterweight adjusting-compacting device " that patent announcement number is CN2895364Y and patent announcement number are that " a kind of elevator counterweight block compressing structure " disclosed structure of CN202988499U is also the structure that pressing plate and attaching parts fix to clamp counterweight vertical beam.Although no longer machining hole of its straight beam, utilizes gripping power to be applied on pressing plate, can reach the object of fixing counterweight., fix respectively the paired attaching parts of clamping with the both sides of pressing plate because it adopts bolt, fix to clamp by bolts and nuts and combine realization, therefore compression is also very inconvenient to the operation of pouring weight downwards for pressing plate.Although this compressing structure can be installed on the diverse location of different counterweight vertical beams, avoid perforate in counterweight vertical beam, but the shape after the bending of attaching parts coordinates the gripping power producing to be greatly affected with bolt contact surface, the gripping power being applied on pressing plate can weaken, easily there is the loosening of pressing plate, be unfavorable for being fixed pouring weight.

Utility model content

The purpose of this utility model is to provide a kind of Elevator weight sensor anti-drop device, solve inconvenient operation that existing pressing plate fixed form exists, easily become flexible, be unfavorable for problems such as being fixed of pouring weight, it is simple in structure, reasonable in design, manufacture, charge and discharge operations easily, conveniently, have saving of labor, material-saving, reduce costs, reduce operator's labour intensity, improve the feature that is fixed effect and enhancing operation stability of counterweight housing of elevator.

The technical scheme that the utility model adopts is: this Elevator weight sensor anti-drop device comprises support body, be assembled on support body to pouring weight and fastening assembly, it is characterized in that: described fastening assembly is made up of the U-shaped chuck and the locking screw screw bolt and nut that are sleeved on the symmetrical layout in support body vertical beam, the open end of U-shaped chuck inserts along the length direction of support body vertical beam cross-sectional plane, and compress pouring weight, utilize and be fixed together through locking screw screw bolt and nut and the support body vertical beam of U-shaped chuck open end connecting bore.

The sealing end of described U-shaped chuck and the width of open end, be consistent with the width of support body vertical beam cross-sectional plane.

Advantage and the good effect that the utlity model has are: because the utility model adopts the fixing disconnecting prevention structure form to pouring weight of U-shaped chuck, replace the fastening form to pouring weight of pressing plate of utilizing termination pressing plate and brace pressing plate etc. in existing like product, so not only make it simple in structure, reasonable in design, and manufacture, charge and discharge operations be all very easy to, convenient.In addition, because U-shaped chuck size is little, easily processing, can be used sheet material to cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing or sheet material clout processing completely, therefore saving of labor, material-saving.Therefore, this anti-drop device has and reduces costs, reduce operator's labour intensity, improve being fixed effect and strengthening the feature of operation stability of counterweight housing of elevator, solved inconvenient operation that existing pressing plate fixed form exists, easily become flexible, be unfavorable for problems such as being fixed of pouring weight.
