Abstract
The utility model relates to a wire rope traction type hoisting quantity limiter for construction lifters for lifting goods. The utility model is composed of a set of spring deforming device, a pulley set, two limit switches, a bracket, an installing cross beam, etc., and is installed on definite height of a guiding rail rack of a wire rope lifter. When a traction wire rope winds the pulley set, the tension of the traction wire rope rotates a lever arm plate round a hinge pin shaft on the lower end of the lever arm plate and drive a draw rod hinged on the upper part of the arm plate to move overcoming the tension of the spring, an adjustable colliding block fastened on the draw rod can trigger the limit switches by a displacement amplifying mechanism for cutting off power supplies or sending out alarm signal. When the utility model is used for lifting heavy objects, the utility model can enhance the using safety of wire rope lifters by limiting the lifting and loading weight of wire rope lifters. The utility model has the advantages of simple structure and convenient use and maintenance.
Description
The utility model relates to a kind of vehicle for construction safety device, is used for rope traction formula goods building hoist, when promoting weight, by limiting the weight of its lifting load, to improve the safety of elevator operation.
Existing steel rope elevator does not have the safety device of special-purpose restriction hoisting capacity, is a big potential safety hazard of this kind equipment always.In order to use this kind equipment safely, the camp site has takes following measure:
1, at the cage top one weight-measuring device is installed, its control cable with the cage up-and-down movement, causes the maintenance of cable to have some problems by the cage towing, and in high-building construction, along with increasing of guide rail bracket, problem is more serious especially.
2, weight-measuring device is installed at the guide rail bracket top, along with increasing of guide rail bracket, this device also must move up thereupon.Cause the work capacity of its lifting, adjustment, maintenance to roll up, thereby increased considerably working strength of workers.
Because the vice proper of such scheme itself, and this class weight-measuring device be not for the steel rope elevator custom-designed.Therefore design a kind of more safe and reliable, working service easily steel rope elevator freight weight limit device be the task of top priority.
The purpose of this utility model is to provide a kind of safe and reliable, working service steel rope elevator load lifting limiter easily, overcomes the above-mentioned defective of prior art, further improves the safety performance of steel rope elevator.
Technical solution of the present utility model is a kind of rope traction formula goods building hoist load lifting limiter, by a sleeve spring anamorphic attachment for cinemascope, assembly pulley, two limit switches and spacing stroke enlarger, compositions such as mounting bracket, direct mount is on the elevator guide rails frame, three pulley triangularities are arranged and are formed assembly pulley, one of them pulley is installed on throw of lever plate middle part, two pulleys are installed on the support in addition, the throw of lever plate is vertically installed, the lower end is hinged with bearing pin and support, the upper end is hinged with a pull bar, pull bar is that level is installed, and the adjustable collision block of tensioning spring and triggering limit switch power on/off is installed on the pull bar.Traction is walked around assembly pulley with steel rope, assembly pulley makes the crooked horizontal pull that produces of steel rope, pull lever arm plate rotates around its lower end hinging pin shaft, and drive and arm plate upper end pivotally attached pull bar overcome the tension force of spring and move, make the adjustable collision block that is fastened on the pull bar trigger limit switch, thereby cut off the electricity supply or send alerting signal by displacement amplifying mechanism.When promoting weight,, improved the safety that the steel rope elevator uses by limiting the weight of its lifting load.Adapt with the hauling rope quantity of rack winch, the pattern of single rope, duplex type and many ropes is arranged.
Description of drawings is as follows:
Figure one is the utility model steel rope elevator load lifting limiter structural representation;
Load lifting limiter structure left view when figure two is the duplex type traction;
Figure three is single load lifting limiter structure left views when drawing of restricting;
Figure four is that limit switch is installed and adjustable collision block position view;
Figure five is spacing stroke enlarger scheme of installations.
With reference to accompanying drawing, further specify as follows in conjunction with specific embodiments:
Realize load lifting limiter of the present utility model, shown in figure one.Form a sleeve spring anamorphic attachment for cinemascope by throw of lever plate (3), hinging pin shaft (6), pull bar (9), spring (15), step disk (16) and jam nut (17), packing ring (14) etc.Throw of lever plate (3) lower end is hinged with connecting pin 1 and support 2, and the other end and pull bar (9) are hinged.Spring is installed on the pull bar (9) by step disk.Form assembly pulley by three pulleys (5), one of them pulley is installed on throw of lever plate (3) middle part, and other two pulleys are installed on the support (2).The adjustable collision block (11) and the jam nut (13) that trigger the limit switch power on/off are housed on the pull bar (9).Limit switch (18) is installed on the travel switch adapter plate on the support (20), and has rainproof cover (25) to hide, as figure four.Spacing stroke enlarger (10) is installed on the support (2), as figure five, amplifies bar (26), roller (27), torsion spring (28) and bearing pin (29) etc. by displacement and forms.In addition, also be provided with anticreep rope bar (4), (24).
The deflection of spring device is installed on the support (2) by bearing and bearing pin (7), clamp (8) etc. by bearing pin (1) and pull bar (9), assembly pulley, becomes an assembly.In the present embodiment, this assembly is by bolt group (21) and fastening connection of mounting rail (19) as anchor fitting, and mounting rail (19) two ends are fixed on the certain altitude of steel rope elevator guide rails frame (22) with hook bolt (20).As figure two, figure three.
After the utility model load lifting limiter firmly is installed on steel rope elevator guide rails frame head tree (22), the haulage cable of winch (23), pile warp assembly pulley (5), ginseng figure two, figure three.The steel wire rope tension that hoisting heavy produces, pull lever arm plate (3) rotates around its connecting pin (1), and drive and throw of lever plate upper end pivotally attached pull bar (9) overcome the tension force of spring (15) and move, make the adjustable collision block (11) that is fastened on the pull bar trigger limit switch, thereby cut off the electricity supply or send alerting signal by displacement amplifying mechanism (10).
Adjust the position of two adjustable collision blocks (11) (as figure four A1, A2), two limit switches (18) (as figure four B1, B2) are cut off the power supply under corresponding different hook load or report to the police.Jam nut (13) should be locked after the adjustment.
The utility model load lifting limiter has improved the security performance of steel wire rope lift, with Prior art compares, and its advantage is safe and reliable, and is simple in structure, and working service is convenient, peace Fill highly lowly, and must not change the installation site with the rising of guide rail bracket, have good popularization Using value.
