Description

Technical Field

[0001] The utility model belongs to the technical field of gates and their accessories, and particularly relates to an automatic gate opening adjustment device. Background Art

[0002] In recent years, with the modernization, intelligence, unmanned production and mechanization of mines, mechanical equipment such as scrapers, belt conveyors, elevators, belt coal feeders, hydraulic gates and other equipment have gradually adopted remote centralized operation, which can realize remote start and stop control of equipment, remote reading of data and status, reduce on-site manual operation, realize unmanned operation, improve the level of automation control, and automatic adjustment of gate opening size is conducive to the precise control of material throughput.

[0003] A Chinese patent application (or patent) with the announcement number CN206590519U discloses an auxiliary detection device for the opening and closing degree of a gate, wherein a displacement sensor includes a chute and a slider placed in the chute, the chute is fixedly arranged on a bracket, and the bracket is fixedly connected to the support channel steel of the chute or the warehouse scraper, and the slider is connected to the gate through a connecting piece. Obviously, during the opening and closing process of the gate, the slider is driven to slide along the chute by the connecting piece, so the relative position of the slider and the chute can reflect the current position of the gate, that is, the relative position of the slider and the chute has a unique corresponding relationship with the opening and closing degree of the gate. The displacement sensor mainly obtains the corresponding detection signal according to the relative position of the slider and the chute in real time, and outputs the detection signal to the coal blending control system, so that the coal blending control system can obtain the opening and closing degree of the gate. The above device can assist the coal blending control system to obtain the position of the gate in real time and continuously, and then the coal blending control system can adjust the coal blending process more accurately according to the specific position of the gate.

[0004] The above-mentioned auxiliary detection device for the opening and closing degree of a plug-in gate has a bracket on which a plug-in gate is inserted, and a cylinder for opening and closing the plug-in gate is also installed on the bracket. The plug-in gate is pushed by the cylinder to slide on the bracket, thereby adjusting the opening and closing degree of the gate. However, one side of the gate is in direct contact with the material and squeezed by the material, so that part of the material will be retained directly below the gate when the material flows out through the gate. At this time, the gate is closed, which will form a great pressure on the material below it, which will not only cause the crushing of this part of the material, but also seriously affect the closing degree of the gate; and, a displacement sensor is also arranged on it, which mainly detects in real time according to the relative position spacing between the slider and the slide slot, so as to judge the opening and closing degree of the gate in the bracket, but because the switching state of the gate is an up and down hoisting action, when detecting the real-time position spacing, the displacement sensor will be affected by the vibration of the opening and closing action of the gate and affect the final detection result, thereby causing the problem of inaccurate detection result of the gate opening and closing degree. To this end, we provide a gate opening automatic adjustment device to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0030] Specifically, a side groove 102 for installing the equipment rack 3 is opened on the side outer wall of the gate frame 1, and an instrument box 4 and a control box 5 are installed inside the equipment rack 3. A door frame groove 101 is provided on the gate frame 1, and the top of the door frame groove 101 is rotatably connected to the gate plate 2. Detection components 8 are installed at both ends of the top of the gate frame 1.

[0031] Furthermore, top grooves 103 are opened at both ends of the top of the gate frame 1, and the detection component 8 includes a pull-wire displacement sensor 801 fixedly installed in the top groove 103, and a flexible steel wire rope 802 is also fixedly installed at the detection end of the pull-wire displacement sensor 801, and the other end of the flexible steel wire rope 802 is fixedly installed on the top of the slide rail 701 through a fixing ring 803.

[0032] The operation process of this embodiment is as follows: one end of the flexible steel wire rope 802 is fixed on the gate plate 2, and the other end is connected to the pull-wire displacement sensor 801. When the gate plate 2 is opened or closed, the flexible steel wire rope 802 is driven to move. The pull-wire displacement sensor 801 calculates the opening size of the gate plate 2 by detecting the length of the flexible steel wire rope 802 pulled out, and displays the value on the instrument box 4. The instrument box 4 feeds back the opening information to the DCS system of the control box 5 through the communication system, and finally it can be displayed on the upper computer of the control box 5.

The core component of the wire displacement sensor 801 in this device is a photoelectric encoder, which has high precision and fast response speed. The repeatability accuracy of detecting the opening size of the gate 2 can reach 0.01%. Example 2

[0033] See also Figure 3-4 On the basis of Example 1, a material blocking assembly 6 is further provided. By utilizing the rotating rod 602 in the material blocking assembly 6 and the return spring 602a on its shaft end, the material blocking plate 601 can be flipped to a horizontal state when not constrained by the gate plate 2, and when subjected to force, it is attached to the outer wall of the gate plate 2, thereby closing the bottom of the gate frame 1 and preventing materials from being retained at the bottom of the gate frame 1.

[0034] Specifically, a material blocking assembly 6 is provided at the bottom of the door frame groove 101 of the gate frame 1, and the material blocking assembly 6 includes a rotating rod 602 inserted into the bottom of the gate frame 1, and the rotating rod 602 is sleeved on the material blocking plate 601, and an abutment spring 601a is fixedly installed on the outer wall of the side of the material blocking plate 601 facing the gate plate 2, and the gate plate 2 is connected to the abutment plate 601b through the abutment spring 601a.

[0035] Furthermore, return springs 602a are installed on both side axial ends of the rotating rod 602, and a sleeve 602b is also installed on the outside of the return spring 602a. The sleeve 602b is fixed on the gate frame 1, and the baffle plate 601 abuts against the outer wall of the gate plate 2 through the abutment plate 601b.

At the same time, the baffle plate 601 also flips synchronously and finally presents an inclined state, and the logistics on the other side of the gate frame 1 flows out through the baffle plate 601, and then when the gate 2 is closed, the gate 2 gradually forms an extrusion force on the baffle plate 601, causing the baffle plate 601 to flip in the opposite direction until it presents a vertical state, thereby preventing materials from being trapped at the bottom of the gate frame 1. Example 3

[0037] See also Figure 5-6 On the basis of Embodiment 1 and Embodiment 2, an opening and closing assembly 7 is further provided. By utilizing the cooperation of the hydraulic rod 702 and the slide rail 701, the gate plate 2 can be pushed to rotate in the gate frame 1, thereby achieving the effect of adjusting the opening and closing degree of the gate plate 2.

[0038] Specifically, plate grooves 201 are opened on both sides of the gate plate 2, and the plate grooves 201 are used to install the slide rails 701.

[0040] The operation process of this embodiment is as follows: when in use, the hydraulic rod 702 is controlled by the control box 5. When the hydraulic rod 702 is extended, the sliding shaft 701a on the shaft end thereof slides in the sliding rail 701, thereby pushing the sliding rail 701 to flip outward. Since the sliding rail 701 is fixedly connected to the gate plate 2, it can push the gate plate 2 to flip, thereby achieving the effect of opening the gate plate 2, and vice versa, closing the gate plate 2.
