AI Technical Summary
The jaw gate is prone to corrosion in a humid environment immersed in water. The cylinder stroke and the gate action are not on the same plane, resulting in the gate not being closed in place, the water slag overflow, and the gap between the gate increases after long-term use and cannot be adjusted. It is often necessary to weld or manually block to prevent slag leakage.
A jaw gate is designed. By setting a copper sleeve at the rotating connection between the active gate and the driven gate and the hopper, a copper sleeve is also set at the rotating connection between the hydraulic cylinder and the hydraulic cylinder base, and the hinge between the hydraulic cylinder and the active gate, which increases the oil nozzle design for regular lubrication to ensure the flexibility of the movable joints. At the same time, a slag stop plate is added on the lower sides of the active gate and driven gate, and an external pressure nylon slag stop plate and filter leakage port are designed on the hopper side to prevent slag leakage and improve drainage efficiency.
Through regular lubrication and copper sleeve design, the corrosion and flexibility of the gate moving joints are solved, the linearity and coordinated action of the gate are ensured, the water slag overflow and slag leakage is avoided, maintenance costs and labor costs are reduced, and on-site 5S management is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loading and unloading equipment, in particular to a jaw gate. Background Technique
[0002] The jaw gate of the water slag bin in the blast furnace water slag yard is used for discharging materials from the slag bin. Due to the design defects of the gate and long-term working in a humid environment immersed in water, the following problems exist:
[0003] 1. There is no lubrication measure for the movable joints of the gate trunnion and the cylinder trunnion, which is extremely easy to corrode and rust, resulting in jamming. As a result, the cylinder stroke and the gate movement are not in the same plane, causing the gate to be extruded and deformed, the gate to close incompletely, and the water slag to overflow.
[0004] 2. The gate has been used for a long time, and due to the erosion of the water slag on the lower gate opening, the gap between the two gates is getting larger and larger, and it cannot be adjusted by adjusting the cylinder stroke. Usually, the form of welding threaded steel at the lower part of the gate is used for repair to prevent the water slag from overflowing.
[0005] 3. Since there is no slag baffle at the lower material opening of the gate, the gap between the gate and the hopper is too large and cannot be adjusted. Usually, the method of manually blocking the woven bag is often used for leakage prevention to prevent the water slag from overflowing.
[0006] The on-site solution measures for the above problems cannot be fundamentally solved. Because the welding part can only be welded on one side, it is easy to be welded off after being squeezed by the water slag and impacted by the valve movement. The woven bag leakage prevention must be re-blocked after one action, and the water slag overflow occurs repeatedly. This greatly increases the labor employment cost and maintenance cost, and the on-site 5S management is in an uncontrolled state. Content of the Utility Model
[0007] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a jaw gate for solving various defect problems during the operation of the above jaw gate.
[0008] To solve the above technical problem, the technical solution provided by the utility model is as follows:
[0009] A jaw gate includes a hopper, a hydraulic cylinder, a main gate and a driven gate; the main gate and the driven gate are arranged in a left-right mirror image, and after the hopper is placed between them, their ends are respectively rotatably connected to the side walls of the hopper, and a main incomplete gear is fixed to the end of the main gate, and a driven incomplete gear is fixed to the end of the driven gate. The main incomplete gear meshes with the driven incomplete gear. A hydraulic cylinder base is installed and fixed on the horizontal side of the hopper. The cylinder body of the hydraulic cylinder is rotatably connected to the hydraulic cylinder base, and the piston shaft end is hinged to the bottom side edge of the main gate.
[0010] As an improvement, copper bushings I are respectively arranged at the rotational connection positions between both the active gate and the driven gate and the hopper. Copper bushings II are respectively arranged at the rotational connection position between the hydraulic cylinder and the hydraulic cylinder base and at the hinge connection position between the hydraulic cylinder and the active gate. This is used to ensure the flexibility at the joints of the active gate, the driven gate, and the hydraulic cylinder.
[0011] As an improvement, directly below the position where the active gate and the driven gate are in close contact, there is a slag baffle fixed to the lower side of the hopper. This effectively prevents slag leakage between the active gate and the driven gate.
[0012] As an improvement, externally pressed nylon slag baffles are respectively fixed around the bottom of the hopper, and the bottom is enclosed by each externally pressed nylon slag baffle. This allows for clearance fit between the active gate and the driven gate and the hopper respectively, effectively preventing the phenomenon of slag leakage.
[0013] As an improvement, a water leakage port is arranged on the side of the bottom of the hopper, and a filter screen is arranged inside the water leakage port. This is used to improve the drainage efficiency.
[0014] The advantages of the present utility model compared with the prior art are as follows:
[0015] 1. In this new type, copper bushings I are respectively arranged at the rotational connection positions between both the active gate and the driven gate and the hopper, and copper bushings II are respectively arranged at the rotational connection position between the hydraulic cylinder and the hydraulic cylinder base and at the hinge connection position between the hydraulic cylinder and the active gate. Additionally, an oil nozzle design is added for regular lubrication, thereby ensuring the flexibility of the movable joints.
[0016] 2. In this new type, the hydraulic cylinder base is installed on one side of the hopper, thereby ensuring the linearity and coordination of the actions of the hydraulic cylinder and the active gate, and facilitating commissioning and debugging.
[0017] 3. In this new type, a slag baffle is additionally designed under the active gate and the driven gate. When the contact area between the active gate and the driven gate wears, slag leakage will not occur. Moreover, through the design of the externally pressed nylon slag baffle, the clearance fit effect between the active gate, the driven gate, and the hopper is ensured, effectively avoiding the phenomenon of slag leakage.
[0018] 5. In this new type, a water leakage port with a filter screen is designed on one side of the hopper, which can accelerate the drainage rate and reduce the flow of slag - carrying water from various gaps. Description of the Drawings
