The technical scheme is that the device comprises a main body rack (1), a heavy hammer (2), microswitches (6), a fixed pulley block (7), a movable pulley block (8) and steel wire ropes (9), wherein the fixed pulley block, the movable pulley block and the heavy hammer are arranged on the main body rack, the heavy hammer is fixed to the lower end of the fixed pulley group, the steel wire ropes pass through the fixed and movable pulley blocks, and the upper part and the lower part of the main body rack are respectively equipped with the upper limit microswitch and the lower limit microswitch. The device of the utility model has the following advantages that firstly, the main body rack, the heavy hammer, a positioning slide rail, a microswitch rack, a microswitch rack clamp, the microswitches, the fixed pulley block, the movable pulley block and a base are integrated together, allowing batch manufacture in factories; secondly, in-situ assembly is achieved, and the position of the microswitches is easily adjusted; and thirdly, the device has universality and allows batch manufacture and examination.
Description
Affiliated technical field:
The utility model relates to a kind of electric gate valve limiting and protecting device up and down, is applicable to the position limitation protection up and down of water conservancy electric gate valve.
Background technology:
At present; the most more complicated of limiting and protecting device up and down of electric gate valve in the water conservancy industry; particularly for the electric screw gate; there are a lot of problems in the bound protective device; install and adjust all very difficult; and random strong, bring inconvenience for the equipment purchase installation and maintenance, exert heavy pressures on for use department.
The utility model content:
The utility model purpose provides a kind of limiting and protecting device up and down of electric gate valve; main body is finished at produce in factory; on-the-spot Installation and Debugging are extremely easy; electric screw gate applicable to any kind; also be applicable to the electric gate valve of other type; safe and reliable to operation, easy maintenance solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the limiting and protecting device up and down of electric gate valve; comprise main body rack, weight, microswitch, fixed pulley group, running block, wire rope; fixed pulley group, running block, weight are arranged on the main body rack; the running block lower end is fixed with weight; steel wire penetrating fixed pulley group, running block are respectively equipped with upper limit microswitch and lower limit microswitch in the upper and lower of main body rack.
Also be provided with positioning slide on main body rack, weight is provided with draw-in groove and positioning slide is complementary, and guarantees that running block, weight normally move on main body rack.
Main body rack is an elongate in shape, the vertical setting
Said upper limit microswitch and lower limit microswitch are separately positioned on the microswitch support, by the microswitch bracket clamp microswitch support are fixed on the main body rack.
Bottom at main body rack is provided with base.
Said running block or fixed pulley group, the pulley of being with can be single or multiple.
Said microswitch is a travel switch, can be the travel switch of any type or size.
The other end of wire rope is outside main body rack; be fixed on gate screw rod end through screw rod steel cable clip; motion by the gate screw rod moves up and down through wire rope drive weight; and touch upper limit microswitch, lower limit microswitch at the upper limit position of gate screw rod and lower position; by circuitry cuts gate motor power, thereby gate is protected.
Microswitch, fixed pulley group, running block, wire rope, steel cable clip, pulley are the technique known contents.
Adopt the utility model; can use the limiting and protecting device up and down of the electric gate valve made in factory on-the-spot, reach the purpose that the regulating gate motor realizes protecting electric gate valve by the position of adjusting the bound microswitch by simple schematic diagram and just installation and maintenance easily of explanation.
The utlity model has following advantage: 1. main body rack, weight, positioning slide, microswitch support, microswitch bracket clamp, microswitch, fixed pulley group, running block, base are integrated, can make in batches in factory; 2. the limiting and protecting device up and down of the electric gate valve that assembles in factory is installed very simple with a small amount of accessory at the scene; 3. the adjustment of position limited inching switch position is very simple up and down for the limiting and protecting device up and down of mounted electric gate valve; 4. the limiting and protecting device up and down of electric gate valve has versatility, can make in batches and check.
