Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, and in particular to a positioning structure for a mining hydraulic linkage. Background Technology

[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. The mine pressure acts on the hydraulic supports as an external load. In the mechanical system of interaction between the hydraulic supports and the surrounding rock of the mining face, if the resultant force of each support component of the hydraulic support is exactly in line with the resultant force of the external load acting on the hydraulic support from the roof, then the hydraulic support is well adapted to the surrounding rock of the mining face. Connecting rods are installed on mining hydraulic supports to connect the base and the top seat of the hydraulic support. The connecting rods are cylindrical. During the processing of the connecting rods, they are positioned. This positioning structure is used to position the connecting rods.

[0003] When positioning hydraulic support connecting rods, the bottom of the connecting rod is prone to sagging due to its own weight, which can cause problems during subsequent processing and is not safe. Utility Model Content

[0004] The purpose of this invention is to provide a positioning structure for a mining hydraulic linkage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning structure for a mining hydraulic linkage includes a base, with fixed seats installed at the upper ends of both the left and right sides of the base. A rotating shaft passes through the middle of the fixed seat, and a rotating seat is installed on the side of the rotating shaft near the center of the base. A screw passes through the top wall of the fixed seat, and a hollow opening passes through the middle of the rotating seat. A lead screw passes through the end wall of the rotating seat near the center of the base, and a stop plate is installed on one end of the lead screw. A through hole passes through the end wall of the lead screw near the stop plate, and a pin is installed inside the through hole. A lower opening passes through the bottom wall of the middle part of the base, and a screw passes through the upper wall of the base near the lower opening. A displacement seat is installed on the upper end of the screw, and transmission rollers are installed at both the left and right ends of the top of the displacement seat.

[0007] Preferably, the base and the fixed seat are fixedly connected, and there are two fixed seats, which are symmetrically distributed about the center of the base.

[0008] Preferably, the fixed base is rotatably connected to the rotating base via a rotating shaft, and the rotating base and the lead screw are threaded together, with one end of the lead screw extending into the hollow opening and the other end extending to the outside of the rotating base.

[0009] Preferably, the lead screw is movably connected to the pin through a through hole, and the lead screw and the pin are perpendicular to each other.

[0010] Preferably, the abutment plate is fixedly connected to the lead screw, and the abutment plate is disc-shaped.

[0011] Preferably, the base and the screw are rotatably connected, the screw and the displacement seat are threadedly connected, and the displacement seat and the transmission roller are rotatably connected.

[0012] The utility model has at least the following beneficial effects:

[0013] The displacement seat and the drive rollers are rotatably connected. When the screw rotates, the screw drives the displacement seat to move, causing the displacement seat to move vertically relative to the base. Consequently, the two drive rollers move upward to abut against the bottom of the connecting rod, thus supporting the connecting rod and preventing the drive rollers from falling due to excessive weight.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a positioning structure for a mining hydraulic linkage:

[0022] like Figure 1-4 As shown, a positioning structure for a mining hydraulic linkage includes a base 1, with fixed seats 2 installed at the upper ends of both the left and right sides of the base 1. The base 1 and fixed seats 2 are fixedly connected, and there are two fixed seats 2, which are symmetrically distributed about the center of the base 1. A rotating shaft 3 passes through the middle of the fixed seat 2, and a rotating seat 4 is installed on the side of the rotating shaft 3 near the center of the base 1. A screw 13 passes through the top wall of the fixed seat 2, and a hollow opening 5 passes through the middle of the rotating seat 4. A lead screw 6 passes through the end wall of the rotating seat 4 near the center of the base 1, and a stop plate 9 is installed on one end of the lead screw 6. The fixed seat 2 is connected by... The rotating shaft 3 is rotatably connected to the rotating seat 4, and the rotating seat 4 and the lead screw 6 are threadedly connected. One end of the lead screw 6 extends into the hollow opening 5, and the other end extends to the outside of the rotating seat 4. When the lead screw 6 rotates, the lead screw 6 moves horizontally along the rotating seat 4, causing the abutment plate 9 to move laterally. The two abutment plates 9 move closer together to clamp and limit the side end wall of the horizontally placed hydraulic connecting rod. At this time, lubricating oil can be applied to the end wall of the connecting rod for maintenance, or the connecting rod can be placed in a processing equipment, such as a drilling machine, to drill a hole at the top of the connecting rod, so that the connecting rod can be connected to an external structure, such as a hydraulic top seat.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, a through hole 7 is provided on the end wall of the lead screw 6 near the abutment plate 9, and a pin 8 is installed inside the through hole 7. A lower opening 14 is provided on the bottom wall of the middle part of the base 1, and a screw 10 is provided on the upper wall of the base 1 near the lower opening 14. A displacement seat 11 is installed on the upper end of the screw 10, and transmission rollers 12 are installed on both the left and right ends of the top of the displacement seat 11. The lead screw 6 is movably connected to the pin 8 through the through hole 7, and the lead screw 6 is perpendicular to the pin 8. The abutment plate 9 is fixedly connected to the lead screw 6, and the abutment plate... 9 is disc-shaped. The base 1 and screw 10 are rotatably connected, and the screw 10 and displacement seat 11 are threadedly connected. The displacement seat 11 and transmission roller 12 are rotatably connected. When the screw 10 rotates, the screw 10 drives the displacement seat 11 to move, causing the displacement seat 11 to move vertically relative to the base 1. Consequently, the two transmission rollers 12 move upward to abut against the bottom end of the connecting rod, thus supporting the connecting rod and preventing the transmission rollers 12 from falling due to excessive weight.

[0024] Working principle:

[0025] When positioning the connecting rod, the connecting rod is placed horizontally on the transmission roller 12. At this time, rotating the screw 10 moves the transmission displacement seat 11 upward, causing the transmission roller 12 to move upward, thus supporting the connecting rod higher. When the height of both ends of the connecting rod is the same as the height of the rotating seat 4, rotating the lead screw 6 causes the lead screw 6 to move laterally, and the abutment plate 9 is pressed tightly against the side wall of the connecting rod, thus simply limiting the position of the connecting rod. The pin 8 can be inserted into the through hole 7. By bending the pin 8, the lead screw 6 is rotated, allowing the abutment plate 9 at the side end of the lead screw 6 to fit more tightly against the end wall of the connecting rod, thus firmly positioning the connecting rod and facilitating subsequent safe processing of the connecting rod, such as drilling or applying lubricant. The rotating shaft 3 rotates to rotate the rotating seat 4, thereby driving the positioned connecting rod to rotate, facilitating the switching of the end wall position of the connecting rod for further processing. Tightening the screw 13 limits and positions the rotating seat 4 and the connecting rod.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
