Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a hoisting mechanism for a coal quantity detection device in a mine. Background Technology

[0002] Coal production is a crucial indicator for measuring the economic efficiency of coal mining enterprises. Coal quantity monitoring at each stage of production not only serves as the basis for production statistics and management but also provides vital material feedback information for process control and optimization. Currently, belt conveyors are the most widely used equipment in coal production. However, due to the uneven distribution of coal mining, the coal transport capacity of these conveyors cannot remain stable, often resulting in suboptimal operation where the conveyors are underutilized and consume excessive amounts of electricity.

[0003] In the prior art, patent document CN107424143B discloses a method for detecting coal quantity in a mining belt conveyor based on binocular stereo vision depth perception. Unlike setting a corresponding coal quantity detection unit at the bottom of the conveyor, this scheme uses a camera set above the conveyor belt to collect images of the transported coal and transmit them to a host computer. Accordingly, the hardware equipment used for detection needs to be installed above the conveyor belt, thus requiring a hoisting mechanism. For example, patent document CN219384572U discloses a hoisting locking device, which uses a fixed support carrying a hook for hoisting. The bottom of the fixed support is movably connected to the inner wall of the base, thereby enabling the hoisting device to rotate. A locking component is fixedly connected to the bottom of the fixed support.

[0004] Based on this, this application aims to propose a hoisting mechanism for a coal quantity detection device in mines that is different from the aforementioned prior art and has a simpler structure. Utility Model Content

[0005] This utility model addresses the aforementioned problems in the prior art by providing a hoisting mechanism for a coal quantity detection device in a mine. This mechanism is used to install the coal quantity detection device above a conveyor belt and features a simple structure that is easy to operate, saves manpower, and improves efficiency.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hoisting mechanism for a coal quantity detection device in a mine, characterized in that it includes a hoisting rod and a base for supporting the hoisting rod, the base having an installation position for connecting a conveyor; a hook assembly is installed on the hoisting rod, the hook assembly including a take-up and release frame, a hoisting rope wound on the take-up and release frame, and a motor for driving the take-up and release frame to rotate, the end of the hoisting rope being connected to a hook; the hoisting rod is rotatably connected to the base through a slewing bearing, and a locking mechanism for locking the hoisting rod and the base is also provided.

[0007] Furthermore, the locking mechanism includes a limiting cylinder fixed to the base and an adjusting rod connected to the limiting cylinder. One end of the adjusting rod is inserted into the limiting cylinder and threaded to the limiting cylinder through its outer wall. The other end of the adjusting rod is located outside the base and connected to a handle. An adjusting block is fixedly connected to the adjusting rod inside the limiting cylinder. The lifting rod is inserted into the base and adjacent to the adjusting block, and the axis of the adjusting rod is perpendicular to the axis of the lifting rod. The outer wall of the adjusting block is provided with an adjusting inclined surface adapted to the side wall of the lifting rod, so that as the adjusting rod is screwed in or out, the adjusting inclined surface abuts against the side wall of the lifting rod to lock the lifting rod to the base.

[0008] Furthermore, the adjusting block and the adjusting rod are fixed coaxially, and the adjusting block is configured as a conical structure.

[0009] Furthermore, the adjusting block corresponding to the boom is provided with an annular groove along its circumference.

[0010] Furthermore, the base includes a base body and a bottom support cylinder fixed to the base body. The mounting position is located on the base body, the limiting cylinder is fixed to the bottom support cylinder, and the lifting rod is rotatably connected to the base body through a slewing bearing. The bottom of the lifting rod is inserted into the bottom support cylinder and rotatably connected to the bottom support cylinder.

[0011] Furthermore, a push rod is also fixed on the boom.

[0012] Furthermore, a limiting ring fixed to the motor and through which the hoisting rope passes is provided on the lower side of the take-up and take-down frame.

[0013] Furthermore, the boom is inverted L-shaped, comprising a horizontal bar and a vertical bar. When the base is installed on the transport machine via the mounting position, the horizontal distance between the mounting position and the target position is the same as the length of the horizontal bar of the boom.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a lifting rod, a base for supporting the lifting rod, and a hook assembly installed on the lifting rod, and a locking mechanism between the lifting rod and the base for locking the two, can fix the base to the corresponding frame of the conveyor. By pushing the lifting rod by hand to make it rotate around the base, the coal quantity detection device hanging on the hook assembly can be lifted and installed on the corresponding frame above the conveyor. After the lifting is completed, it is locked by the locking mechanism. There is no need for transmission gears or other components. The structure is simple and the operation is convenient.

[0016] 2. This utility model further utilizes a locking mechanism mainly composed of a limiting cylinder, an adjusting rod, and an adjusting block. By using the threaded connection between the adjusting rod and the limiting cylinder, as well as the shape of the adjusting inclined surface of the adjusting block, the lifting rod can be quickly locked to the base by screwing in the adjusting rod, and unlocked by screwing out the adjusting rod. The locking operation is very convenient and inexpensive. Attached Figure Description

Detailed Implementation

[0021] The principles and features of this utility model are described below. The embodiments given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0022] like Figure 1 As shown, the hoisting mechanism of the coal quantity detection device in this embodiment includes a hoisting rod 2 and a base 1 for supporting the hoisting rod 2. The base 1 has an installation position 10 for connecting a conveyor. The hoisting rod 2 is an inverted L-shape, which includes a horizontal bar and a vertical bar. A push rod 6 is fixed on the hoisting rod 2. A hook assembly 3 is installed at the top end of the hoisting rod 2. The hook assembly 3 includes a take-up frame 31, a hoisting rope 32 wound on the take-up frame 31, and a motor 33 for driving the take-up frame 31 to rotate. A limiting ring 7 fixed to the motor 33 is provided on the lower side of the take-up frame 31 for the hoisting rope 32 to pass through, to prevent the hoisting rope 32 from swinging excessively. A hook 34 is connected to the end of the hoisting rope 32. The hoisting rod 2 is rotatably connected to the base 1 through a slewing bearing 4. A locking mechanism 5 for locking the hoisting rod 2 and the base 1 is also provided between the hoisting rod 2 and the base 1.

[0023] Specifically, the base 1 in this embodiment includes a base body 11 and a bottom support cylinder 12 fixed to the base body 11. The mounting position 10 is located on the base body 11. The limiting cylinder 51 is fixed to the bottom support cylinder 12. The lifting rod 2 is rotatably connected to the base body 11 through a slewing bearing 4. The bottom of the lifting rod 2 is inserted into the bottom support cylinder 12 and rotatably connected to the bottom support cylinder 12. The bottom of the lifting rod 2 is rotatably connected to the bottom support cylinder 12 through a bearing.

[0024] When hoisting the coal quantity detection device, the base 1 is fixed to the side frame of the conveyor 7 via the mounting position 10, and the horizontal distance between the mounting position 10 and the target hoisting position is approximately equal to the length of the crossbar of the hoisting rod 2. The purpose is to hoist the coal quantity detection device directly above the target position by manually pushing the push rod 6 to rotate the hoisting rod 2 around the base 1 to a suitable angle.

[0025] In a preferred embodiment of this utility model, the locking mechanism 5 includes a limiting cylinder 51 fixed to the base 1 and an adjusting rod 52 connected to the limiting cylinder 51. One end of the adjusting rod 52 is inserted into the limiting cylinder 51 and threadedly connected to the limiting cylinder 51 through its outer wall. The other end of the adjusting rod 52 is located outside the base 1 and connected to a handle 53. An adjusting block 54 is fixedly connected inside the limiting cylinder 51 and the adjusting rod 52. The lifting rod 2 is inserted into the base 1 and adjacent to the adjusting block 54, and the axial direction of the adjusting rod 52 is perpendicular to the axial direction of the lifting rod 2. The outer wall of the adjusting block 54 is provided with an adjusting inclined surface adapted to the side wall of the lifting rod 2, so that as the adjusting rod 52 is screwed in or out, the adjusting inclined surface abuts against the side wall of the lifting rod 2 to lock the lifting rod 2 to the base 1. Specifically, the adjusting block 54 is fixed coaxially with the adjusting rod 52, and the adjusting block 54 is configured as a conical structure. When the adjusting rod 52 is turned in by the handle 6, the conical adjusting block 54 is also turned in. Since its diameter is smaller on the inside and larger on the outside, the larger diameter peripheral wall of the adjusting block 54 will gradually come into contact with the side wall of the boom 2 during the turning process, eventually locking the boom 2 to the base 1. Conversely, when unlocking is required, simply turn the adjusting rod 52 out by the handle 6 to release the contact between the adjusting block 54 and the side wall of the boom 2, thus unlocking the boom and restoring it to its rotatable state.

[0026] Preferably, the rod 2 is provided with an annular groove 21 along its circumference for the adjusting block 54, which facilitates the adjustment block 54 to be rotated in or out while also limiting its vertical position to a certain extent.
