Description

Technical Field

[0001] This utility model relates to the field of mining engineering equipment technology, and in particular to a wellbore construction hoisting device for mining engineering. Background Technology

[0002] A hoisting platform is a work platform that is suspended and raised within the shaft during the construction of a vertical shaft. When the hoisting platform is lowered into the shaft, its edges are very likely to collide with the shaft wall, which can damage both the shaft and the hoisting platform. Furthermore, the swaying of the hoisting platform poses a significant safety hazard.

[0003] For example, Chinese Patent Publication No. (CN217051437U) discloses a wellbore construction hoisting device for mining engineering, which describes: "It includes a base, on which a mounting frame is provided, a spring rod is connected to one side of the mounting frame, one end of the spring rod is connected to the base, a roller is provided on the mounting frame, and the roller contacts the inner wall of the wellbore; both the base and the mounting frame are provided with connectors for easy installation. This wellbore construction hoisting device for mining engineering differs from the prior art. Through the combined use of connectors and expansion components, when the roller needs to be replaced, it is only necessary to pass the connecting rod through the mounting hole and the roller, and use the expansion component to connect the roller to the mounting frame. The installation steps are few and convenient. At the same time, during installation, the mounting hole squeezes the baffle, compresses the spring and the telescopic rod. When the baffle passes through the mounting hole, the spring restores the baffle and limits the connecting rod, which can effectively prevent the roller from vibrating against the inner wall of the wellbore when it rotates, thus preventing the connection from becoming loose."

[0004] In summary, the existing hoisting platform guiding devices have the following technical problems: Most of the guiding devices currently used are single-sided guides, with the guide wheel generally located above or below the hoisting platform. However, after the mine is excavated, the tunnel wall is sprayed with cement mortar to keep it as flat as possible. However, the cement spraying is not uniform and only serves to strengthen the tunnel wall. When the single-sided pulley guide moves to the other side, the tunnel wall on the other side may have large and uneven protrusions, causing the outer ring of the hoisting platform to collide with the protrusions, which in turn causes the hoisting platform to shake. Therefore, it is necessary to propose a hoisting platform guiding device for mine engineering shaft construction, and to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0005] Based on this, it is necessary to provide a guiding device for a shaft construction platform in mining engineering to address the above-mentioned technical problems. By setting up a guiding support structure, two sets of guiding support structures are symmetrically arranged on the upper and lower sides of the platform. At the same time, the two sets of contact wheels are connected by a linkage gear. When one side of the contact wheel becomes dynamic, the other side of the contact wheel moves synchronously, thereby avoiding collision between the platform and the tunnel wall. If the rotation limit of the linkage gear is reached, the secondary protective wheel can contact the tunnel wall to provide secondary protection for the platform, thereby preventing the platform from shaking.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A guiding device for a shaft construction platform in mining engineering.

The rear end of the machine body support frame is symmetrically fixedly connected with a hanging plate clamp.

[0012] As a preferred embodiment of the wellbore construction hoisting device for mining engineering provided by this utility model, the guide support structure includes gear shafts symmetrically rotatably disposed inside the machine body support frame, with linkage gears fixedly connected to the surfaces of the two gear shafts respectively, and the linkage gears meshing with each other, and an end shaft rotatably connected to the surface of the gear shaft, with a contact wheel fixedly connected to the surface of the end shaft.

[0013] As a preferred embodiment of the wellbore construction hoisting device for mining engineering provided by this utility model, the number of support arms is two, both of which are fixedly connected to the surface of the gear shaft and are disposed on both sides of the linkage gear, and the contact wheel is disposed in the middle of the two support arms.

[0014] As a preferred embodiment of the wellbore construction hoisting device for mining engineering provided by this utility model, a spring rod is hinged to the top surface of the hoisting plate, and U-shaped support arms are rotatably connected to both ends of the end shaft. The output end of the spring rod is hinged to the surface of the U-shaped support arm.

[0015] As a preferred embodiment of the wellbore construction hoisting device for mining engineering provided by this utility model, the side fixing structure includes an arc-shaped positioning frame disposed in the middle of the hoisting plate. A guide groove is provided through the surface of the hoisting plate. A sliding rod is slidably connected to the inner wall of the guide groove. The arc-shaped positioning frame is fixedly connected to the surface of the sliding rod. A return spring is provided inside the hoisting plate. The two ends of the return spring are fixedly connected to the arc-shaped positioning frame and the machine body support frame, respectively.

[0016] As a preferred embodiment of the wellbore construction hoisting device for mining engineering provided by this utility model, a shaft is fixedly connected inside the machine body support frame, and a secondary protective wheel is rotatably connected to the surface of the shaft. The secondary protective wheel is located at the center of the two contact wheels.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The guiding device for shaft construction platform in mining engineering provided by this utility model has a guide support structure. Two sets of guide support structures are symmetrically arranged on the upper and lower sides of the platform. At the same time, the two sets of contact wheels are connected by a linkage gear. When one side of the contact wheel moves, the other side of the contact wheel moves synchronously, thereby avoiding collision between the platform and the tunnel wall. If the reversal limit of the linkage gear is reached, the secondary protective wheel can contact the tunnel wall to provide secondary protection for the platform, thereby preventing the platform from shaking.

[0019] The guiding device for shaft construction in mining engineering provided by this utility model has a side fixing structure. During equipment installation, the side wall of the hoisting plate is clamped to the middle of the hoisting plate clamp. The arc-shaped positioning frame slides in the middle of the hoisting plate clamp by compression. The sliding of the arc-shaped positioning frame compresses the return spring, so that the arc-shaped positioning frame can always be in close contact with and fixed to the hoisting plate.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background section, most of the guiding devices currently used are single-sided guides. The guide wheel is usually located above or below the hoisting platform. However, after the mine is excavated, the tunnel wall is sprayed with cement mortar to make the tunnel wall as flat as possible. However, the cement spraying is not uniform and can only serve to strengthen the tunnel wall. When the single-sided pulley guide moves to the other side, the tunnel wall on the other side may have large and uneven protrusions, causing the outer ring of the hoisting platform to collide with the protrusions, which in turn causes the hoisting platform to shake.

[0030] To solve this technical problem, this utility model provides a guiding device for a shaft construction platform in mining engineering.

[0031] For details, please refer to Figures 1-4 The guiding device for the shaft construction platform in mining engineering specifically includes, and the machine body support frame 1 also includes:

[0032] The guide support structure 2 is symmetrically arranged at the front end of the body support frame 1;

[0033] The side fixing structure 3 is located at the rear end of the body support frame 1;

[0034] The machine body support frame 1 has two sets of guide support structures 2 symmetrically arranged inside. The two sets of guide support structures 2 are connected by a linkage gear 7. The rear end of the machine body support frame 1 is symmetrically fixed with a hanging plate clamp 4.

[0035] The guiding device for shaft construction platform in mining engineering provided by this utility model has a guide support structure 2. Two sets of guide support structures 2 are symmetrically arranged on the upper and lower sides of the platform. At the same time, two sets of contact wheels 9 are connected by a linkage gear 7. When one side of the contact wheel 9 moves, the other side of the contact wheel 9 moves synchronously, thereby avoiding collision between the platform and the tunnel wall. If the reversal limit of the linkage gear 7 is reached, the secondary protection wheel 13 can contact the tunnel wall to provide secondary protection for the platform, thereby preventing the platform from shaking.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] Example 1:

[0038] Please refer to Figures 1-3 A guiding device for a shaft construction platform in mining engineering, comprising: a body support frame 1, and further comprising:

[0039] The guide support structure 2 is symmetrically arranged at the front end of the body support frame 1;

[0040] The side fixing structure 3 is located at the rear end of the body support frame 1;

[0041] The machine body support frame 1 has two sets of guide support structures 2 symmetrically arranged inside. The two sets of guide support structures 2 are connected by a linkage gear 7. The rear end of the machine body support frame 1 is symmetrically fixed with hanging plate clamps 4.

[0042] Specifically, the side fixing structure 3 includes an arc-shaped positioning frame 16 disposed in the middle of the hanging plate clamp 4. A guide groove 14 is provided through the surface of the hanging plate clamp 4. A slide rod 15 is slidably connected to the inner wall of the guide groove 14. The arc-shaped positioning frame 16 is fixedly connected to the surface of the slide rod 15. A return spring 17 is provided inside the hanging plate clamp 4. The two ends of the return spring 17 are fixedly connected to the arc-shaped positioning frame 16 and the machine body support frame 1, respectively.

[0043] With the above structural design, the device uses a clamping plate 4 to be snapped onto the side wall of the hanging plate. After completion, the clamping plate 4 is pushed toward the side wall of the hanging plate. While pushing, the arc-shaped positioning frame 16 is kept in close contact with the side wall of the hanging plate. The arc-shaped positioning frame 16 pushes the slide rod 15 to slide inside the guide groove 14. At the same time, the return spring 17 is compressed by the arc-shaped positioning frame 16.

[0044] Example 2:

[0045] The guiding device for the shaft construction platform in mining engineering provided in Example 1 is further optimized, specifically, as follows: Figures 2-5 As shown, the guide support structure 2 includes gear shafts 5 symmetrically rotatably disposed inside the body support frame 1. The surfaces of the two gear shafts 5 are respectively fixedly connected to linkage gears 7, and the linkage gears 7 mesh with each other. The surfaces of the gear shafts 5 are rotatably connected to end shafts 8, and the surfaces of the end shafts 8 are fixedly connected to contact wheels 9.

[0046] Specifically, there are two support arms 6. Both support arms 6 are fixedly connected to the surface of the gear shaft 5 and are located on both sides of the linkage gear 7. The contact wheel 9 is located in the middle of the two support arms 6.

[0047] Specifically, a spring rod 11 is hinged to the top surface of the hanging plate 4, and U-shaped support arms 10 are rotatably connected to both ends of the end shaft 8. The output end of the spring rod 11 is hinged to the surface of the U-shaped support arm 10.

[0048] Specifically, the machine body support frame 1 has a fixed internal connection to a shaft 12, and a secondary protective wheel 13 is rotatably connected to the surface of the shaft 12. The secondary protective wheel 13 is located at the center of the two contact wheels 9.

[0049] Through the above structural design, the spring rod 11 can retract to adjust the distance between the contact wheel 9 and the edge of the hoisting platform. After the hoisting platform is placed inside the mine, the two contact wheels 9 are in close contact with the mine wall. During the descent or ascent of the hoisting platform, the contact wheels 9 rotate synchronously. If the mine wall becomes uneven during movement, the contact wheel 9 pushes the U-shaped support arm 10 through the end pivot 8 to retract the spring rod 11. At the same time, the contact wheel 9 pushes the support arm 6 to move and transmits the transmission to the linkage gear 7 through the gear shaft 5. When the linkage gear 7 on one side rotates, it drives the linkage gear 7 on the other side to rotate synchronously. Thus, the two contact wheels 9 can be synchronously adapted to the state of the mine wall. If the contact wheel 9 rotates inward at too large an angle, the secondary protective wheel 13 will contact the mine wall. This can effectively prevent the edge of the hoisting platform from directly contacting the mine wall.
