Abstract
The utility model discloses a controller for stroke limit, which has the advantage of simple structure, and is used for various hoisting devices, and the controller for stroke limit comprises a housing [3]. The utility model is characterized in that a machine base [4] is arranged in the housing [3], an upper and a lower limit switches [5], [2] and an upper and a lower pull rods [7], [11] are respectively arranged on the machine base [4], an upper and a lower limit springs [6], [10] are arranged among the upper and the lower pull rods [7], [11] and the machine base [4], one end of the upper and the lower pull rods [7], [11] extending out of the machine base [4] is provided with a through hole [9], and the upper and the lower pull rods [7], [11] are connected to the machine base [4] through fine-adjusting nuts [8]. The utility model has the advantages of simple structure, safety and convenience, rain prevention, dust prevention, small size, light weight, etc. When the controller for stroke limit is used, the shape of the original machine is not changed, and meanwhile, the utility model can also prevent wire ropes from being excessively loosened and prevent the wire ropes from being separated form grooves and being disordered on a rotary drum.
Description
Technical field:
The utility model relates to the control setup of all kinds of weight-lifting equipments, specifically a kind of stroke limit controller.
Background technology:
In all kinds of weight-lifting equipments, be preventive device and people's life security, must carry out spacing control to the upper and lower stroke of suspension hook.At present, the general employing when upper limit control hung the method for angling direct collision limit switch, causes the switch rapid wear, offside defective such as out of control, and generally do not have lower limit and control.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, is used for the stroke limit controller of all kinds of weight-lifting equipments.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of stroke limit controller, it comprises shell, be provided with support in the enclosure, be separately installed with the upper and lower limit bit switch on the support, upper and lower pull bar is provided with upper and lower spacing spring between upper and lower pull bar and the support, the end that upper and lower pull bar stretches out support is provided with through hole, and upper and lower pull bar is connected on the support by fine-tuning nut.
The utility model is simple in structure, and described support is inverse-T-shaped.
The utility model is provided with suspension ring for ease of installing on shell.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, safe ready, have rainproof, dustproof, volume is little, characteristics such as in light weight, need not to change former machine shape during use, can prevent also simultaneously that steel rope is unnecessary loosens, and prevents disorder cable on steel rope job-hopping and the rotating cylinder.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, a kind of stroke limit controller, it comprises shell 3, in shell 3, be provided with support 4, be separately installed with upper and lower limit bit switch 5,2 on the support 4, upper and lower pull bar 7,11 is provided with upper and lower spacing spring 6,10 between upper and lower pull bar 7,11 and the support 4, the end that upper and lower pull bar 7,11 stretches out support 4 is provided with through hole 9, and upper and lower pull bar 7,11 is connected on the support 4 by fine-tuning nut 8; For simple in structure, described support 4 is inverse-T-shaped; For ease of installing, on shell 3, be provided with suspension ring 1.
When the utility model uses, shell 3 is fixing with support 4 usefulness screws 12, with suspension ring 1 suspension or be fixed on Tian Liangshang, an end of a backguy is connected with through hole on the top rod 7, the other end is connected with the weight that is through stressed steel rope tail end, and it is normally closed that the deadweight of weight is in upper limit position switch 5; One end of another root backguy is connected with through hole 9 on the lower link 11, the end joint connection of the other end and stressed steel rope, and it is normally closed that the suspension hook deadweight is in lower position switch 2.In the control line difference Access Control case of upper and lower limit bit switch 5,2.By adjusting fine-tuning nut 8, can adjust the position between upper and lower limit bit switch 5,2 and the upper and lower pull bar 7,11.
When suspension hook rose operation, when suspension hook is run into weight, weight rose upper limit spring 6 is resetted, and upper limit position switch 5 often is in to be opened, and cuts off the rising power supply, and suspension hook stops the operation of rising, controlled effectively suspension hook rush to summit or spacing.
When suspension hook descended operation, when suspension hook landed or be obstructed, stressed steel rope lost power, lower limit spring 10 is resetted, and lower position switch 2 often is in to be opened, and cuts off the decline power supply, the suspension hook operation that stops to descend, preventing simultaneously that steel rope is unnecessary loosens, and prevents disorder cable on steel rope job-hopping and the rotating cylinder.
