Background
The jaw crusher is suitable for crushing raw materials in the industries of metallurgy, mine, building and road building, and is divided into various models according to different crushing principles and different sizes of product grades. The crusher is widely used in metallurgy, mine, building and other industries. The jaw crusher drives the eccentric shaft to rotate through the transmission device, the eccentric shaft drives the movable jaw body to do up-and-down reciprocating motion, the movable jaw body changes the motion direction of the movable jaw body into front-and-back motion by taking the toggle plate as a fulcrum, and the movable jaw body generates crushing kinetic energy relative to a fixed amount, so that materials are crushed by multiple times of extrusion and impact.
The hoisting accessory structure of jaw crusher limit backplate among the prior art, as shown in figure 1, go up the limit backplate and when changing at every turn, all will follow the constant head tank and pull out, change the limit backplate at every turn and all propose the limit backplate by lifting by crane wire rope and driving in the groove, because the limit backplate opens the effect of protecting hubei province broken parent and location pinion rack, so, the frequency of dismouting limit backplate is higher.
The jaw crusher is a large-scale high-efficiency material processing device in a mine crushing system, and has the working characteristics of strong crushing capacity, large crushing ratio, stable work, convenient maintenance and the like, so that the jaw crusher is generally used for crushing at the front section of a mine ore crushing process, namely, coarse crushing (a mine is generally three-section crushing, namely, coarse crushing, medium crushing and fine crushing), and once the device fails, the whole process can be stopped.
The jaw crusher needs to be stopped for three times to replace the lining plate and the edge protection plate due to abrasion of the lining plate and the edge protection plate every month, and the maintenance time is prolonged by more than 1 hour due to the difficulty in disassembling the upper edge protection plate. The edge protection plates are protection devices embedded on matrixes on two sides of the jaw crusher, the edge protection plates are firmly fixed on two sides of the matrixes by means of two positioning grooves in the matrixes, and due to the fact that a large amount of dust and machine vibration are generated in the production and crushing process, the edge protection plates and the positioning grooves are tightly stuck together after the dust and the slime enter the edge protection plates and the positioning grooves and are difficult to pull out. In the process of pulling out the side guard plate of the 50-ton travelling crane, the side guard plate and the positioning groove are tightly adhered, so that the main beam of the travelling crane is deformed and then restored to generate huge vibration, the lifting rope is disconnected twice to cause the lifting hook to fly out, and the operation scene is abnormally threatened.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a side guard plate lifting structure to solve the above problems in the prior art.
In order to achieve the purpose, the utility model provides the following technical scheme:
a side guard plate lifting structure comprises a sling, a crane hook and a lever lifting mechanism, wherein the lever lifting mechanism comprises a lifting ring power arm, a lifting ring resistance arm and a lifting ring fulcrum shaft; the hoisting ring fulcrum shaft is correspondingly arranged on the edge protection plate to be hoisted; the end part of the lifting ring power arm is fixedly connected with one end of a sling, the other end of the sling is fixedly connected to the crane hook, and the end part of the lifting ring power arm is pulled through the sling and the crane hook to generate tension on the lifting ring power arm.
Further: the lever hoisting mechanism adopts a lever principle to tilt the side guard plate from the jaw broken matrix, and the sling is connected to a longer force arm of the lever hoisting mechanism, so that the sling can provide less force to provide larger force to the side guard plate.
Further: the length of the lifting ring power arm is five times that of the lifting ring resistance arm, and when the force of ton is applied to the end part of the lifting ring power arm, the tail end of the lifting ring resistance arm can generate the starting moment of ton.
Further: the tip setting of lifting ring resistance arm is in the top of parent step, and when lifting ring power arm was pulled, the tip of lifting ring resistance arm just contacted on the parent step, and when lifting ring power arm received ascending pulling force, the tip of lifting ring resistance arm produced pressure to the parent step downwards, supported the tip of lifting ring resistance arm through the parent step.
Further: the lifting hole is formed in the side protection plate, the lifting ring fulcrum shaft is installed in the lifting hole, and when the lifting ring power arm is pulled upwards, the side protection plate is driven to move upwards through the lifting ring fulcrum shaft, so that the side protection plate is lifted.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has the advantages that firstly, the crane hoisting load is reduced, the capability of pulling out the side guard plate of the crane is improved, secondly, the hoisting of the side guard plate is safe and quick, previously, the side guard plate is directly 'hard-drawn', the side guard plate is slowly tilted through the lever principle, the vibration generated by the previous hoisting of the side guard plate damages equipment and is dangerous to people, the side guard plate is pulled out statically, no sound exists, and the potential safety hazard existing in an operation site for many years is thoroughly eliminated; effectively improves the maintenance efficiency and shortens the time for maintaining the jaw crusher by more than 1 hour each time.
