Description

Technical Field

[0001] The utility model relates to the technology of an overhead passenger vehicle, in particular to a replacement auxiliary device. Background Art

[0002] In the daily production of coal mines, overhead passenger devices are a common means of transportation, used to transport people up and down in the mine. This device drives the steel rope on it to circulate through the rope pulley, thereby realizing the movement of people. However, since the rubber sleeve of the rope pulley will be greatly worn during long-term use, it is necessary to inspect and replace the rubber sleeve or rope pulley with severe wear in time. The traditional replacement method is to stop the operation of the entire passenger device first, and a maintenance personnel will carry a manual hoist to climb onto the beam, put four strands of 8# iron wire on the steel rope, and tie it to the beam (the beam is H-shaped steel, generally located above the rope pulley and perpendicular to the direction of the steel rope), and then tighten the wire to lift the steel rope from the rope pulley, and then another maintenance personnel will remove the old rope pulley or rubber sleeve and install a new one.

[0003] During this replacement process, if the iron wire that ties the steel rope is tightened too much, the iron wire may break, posing a safety issue. In addition, the process of using the iron wire to raise the steel rope is time-consuming, affecting work efficiency. In addition, maintenance personnel need to carry a manual hoist and more iron wire each time to prevent the iron wire from breaking and causing a shortage of iron wire, which brings about the problem of inconvenience in carrying. Finally, the iron wire is lost during this process and the current replacement operation requires two people to work together, which will result in high maintenance costs. Utility Model Content

[0004] The utility model aims to provide a replacement auxiliary device to solve the problems in the prior art of using iron wire to improve the steel rope, such as work efficiency, carrying, maintenance cost, etc.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a replacement auxiliary device, including a hook and a fixed plate, the hook is vertically arranged on the top surface of the fixed plate, and the bottom surface of the fixed plate is vertically arranged with a suspension rod; the lower end of the suspension rod is provided with a movable block, and the two are rotatably matched; the lower end of the movable block is provided with a hook, the hook has a straight portion, the straight portion is sleeved in the movable block, the two are threadedly connected, and the movable block is provided with a first inner cavity used as a movable space for the straight portion.

[0006] The principle of this scheme is: in actual application, use the hook in this scheme to hang on the beam above the rope supporting wheel, then hook the steel rope on the rope supporting wheel with the hook, and then rotate the movable block by hand or with a tool. Since the movable block is connected to the straight part of the hook through a thread, and the hook cannot rotate after hooking the steel rope, rotating the movable block can make the hook gradually rise, thereby lifting the steel rope. When the steel rope is lifted off the rope supporting wheel, the maintenance personnel can replace the rope supporting wheel or the rubber sleeve on the rope supporting wheel.

[0007] The use of this auxiliary device instead of the prior art method of using wire ropes can bring the following benefits:

[0008] 1. The hook of the auxiliary device is hung on the beam, which is convenient and time-saving to install and remove;

[0009] 2. Maintenance personnel only need to bring one auxiliary device when performing maintenance, which is convenient to carry;

[0010] 3. The use of auxiliary devices does not cause wire or other losses, reducing material costs;

[0011] 4. With the auxiliary device, only one maintenance personnel is needed to complete the replacement of the rope pulley or rubber sleeve, which reduces the labor cost.

[0012] Preferably, as an improvement, the suspension rod is threadedly connected to the movable block, and the movable block is provided with a second inner cavity serving as a movable space for the suspension rod.

[0013] In this solution, when the maintenance personnel rotate the movable block, not only the hook can be raised to lift the steel rope, but also the movable block can be raised to lift the steel rope, thereby speeding up the process of lifting the steel rope from the rope support wheel and saving time.

[0014] Preferably, as an improvement, the first inner cavity and the second inner cavity are respectively horizontal through holes, and the two are connected.

[0015] In this solution, the first inner cavity is connected with the second inner cavity to form a horizontal through hole, which simplifies the structure of the movable block and facilitates production. At the same time, when the maintenance personnel rotate the movable block, they can insert a tool such as a steel bar, a handle, etc. into this space for rotation, which facilitates operation.

[0016] Preferably, as an improvement, a limiting ring is provided at one end of the suspension rod close to the movable block.

[0017] In this solution, this design can prevent the maintenance personnel from over-rotating and causing the boom to separate from the movable block.

[0018] Preferably, as an improvement, a limiting ring is provided at one end of the straight portion close to the movable block.

[0019] In this solution, this design can prevent the maintenance personnel from over-rotating and causing the hook to separate from the movable block.

[0020] Preferably, as an improvement, the number of the hooks and the number of the hanging rods are both 2, and the hooks and the hanging rods are respectively located at both ends of the fixed plate.

[0021] In this solution, since a movable block and a hook are connected in sequence under one suspension rod, movable blocks and hooks are connected in sequence under the two suspension rods respectively, which brings two benefits: 1. In actual application, the two hooks will be located on both sides of the highest point of the rope wheel, and hook the steel rope at the same time, and rotate the two movable blocks to lift the steel rope. Compared with the design of one hook, the hook of this design does not need to be raised so high; 2. The fixing plate can also be directly placed across the beam, which is convenient and time-saving.

[0022] Preferably, as an improvement, the center of gravity of the hook is located on the central axis of the boom.

[0023] In this solution, this design can make the auxiliary device have better stability.

[0024] Preferably, as an improvement, the hook is a U-shaped buckle, and the U-shaped buckle lies horizontally on the fixing plate with its opening facing the direction of the crossbeam.

[0025] In this solution, the hook is designed as a U-shaped buckle, which allows maintenance personnel to quickly hang or remove the auxiliary device, saving maintenance time.

[0026] Preferably, as an improvement, the hook and the fixing plate are connected by welding.

[0027] Preferably, as an improvement, the suspension rod and the fixing plate are connected by welding.

[0028] In the above two solutions, since the auxiliary device is used frequently, the use of welding can prevent the hook and / or the suspension rod from accidentally loosening during use, thereby preventing safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a schematic diagram of the structure of Example 1 of the utility model.

[0030] The reference numerals include: a hook 1 , a fixing plate 2 , a suspension rod 3 , a movable block 4 , a hook 5 , and a straight portion 6 . DETAILED DESCRIPTION

[0031] The following is further described in detail through specific implementation methods:

[0032] Embodiment 1, basically as attached Figure 1As shown: A replacement auxiliary device, including a hook 1 and a fixed plate 2, wherein the hook 1 is vertically arranged on the top surface of the fixed plate 2, and a suspension rod 3 is vertically arranged on the bottom surface of the fixed plate 2. Here, the connection between the hook 1, the suspension rod 3 and the fixed plate 2 can be a detachable connection or a fixed connection. Due to the high frequency of use of the auxiliary device, in order to reduce the safety risks caused by the accidental loosening of the detachable connection during use, as an example, the present embodiment adopts a welding connection method. In addition, the hook 1 and the suspension rod 3 will be subjected to force during actual application. Therefore, as a further improvement, the center of gravity of the hook 1 and the suspension rod 3 is designed to be coaxial, so as to ensure the stability of the auxiliary device during application.

[0033] The hook 1 is used to be directly or indirectly hung on the beam. In order to facilitate maintenance personnel to quickly hang or remove the auxiliary device, as an example, the hook 1 is designed in this embodiment to be a U-shaped buckle, such as Figure 1 As shown, the U-shaped buckle lies horizontally on the fixing plate 2, and its opening faces the beam direction. In actual application, the opening of the U-shaped buckle will pass through a horizontal panel on the beam (the beam is actually in a lying H shape) to achieve the purpose of hanging on the beam.

[0034] The auxiliary device is provided with a movable block 4 at the lower end of the suspension rod 3, and the two are rotatably matched. In actual application, when the movable block 4 is rotated, the suspension rod 3 remains stationary due to being fixed on the fixed plate 2, and the portion where the movable block 4 is connected to the suspension rod 3 rotates along the periphery of the suspension rod 3. Here, in addition to the rotational match, the suspension rod 3 and the movable block 4 may or may not be displaced in the axial direction of the suspension rod 3. In order to speed up the process of the steel rope being lifted off the rope support wheel, as a further improvement, the suspension rod 3 and the movable block 4 are designed in this embodiment to have displacement movement in the axial direction of the suspension rod 3. The specific structure is as follows: Figure 1 As shown, the movable block 4 is connected to the suspension rod 3 by threads, and the movable block 4 is provided with a second inner cavity to serve as a movable space for the suspension rod 3. In practical applications, the movable block 4 is rotated, and the movable block 4 and the suspension rod 3 move by thread cooperation. Since the suspension rod 3 is fixed on the fixed plate, the movable block 4 will gradually rise or fall.

[0035] The auxiliary device is provided with a hook 5 at the lower end of the movable block 4, and the hook 5 has a straight portion 6. Figure 1 As shown, the straight portion 6 is sleeved in the movable block 4, and the two are threadedly connected. The movable block 4 is provided with a first inner cavity as a movable space for the straight portion 6. In actual application, the movable block 4 is rotated, and the movable block 4 and the straight portion 6 move through threaded cooperation, so that the hook 5 gradually rises or falls, thereby lifting or lowering the steel rope. Here, it should be understood that when the suspension rod 3 is also threadedly connected to the movable portion 4, the movable block 4 is rotated, so that the movable block 4 and the hook 5 either rise or fall at the same time.

[0036] In the process of using the hook 5 to lift the steel rope, one hook 5 can only hook the steel rope on one side of the rope support wheel. To completely lift the steel rope on the top of the rope support wheel away from the rope support wheel, the steel rope on the hook 5 needs to be lifted to a higher height, which requires a larger force to rotate the movable block 4. At the same time, the auxiliary device is subjected to a larger force at this time, which is easy to cause accidents. As a further improvement, if Figure 1 As shown, the number of hooks 1 and suspension rods 3 is designed to be 2, and the two hooks 1 are respectively located at the two ends of the fixed plate 2, and the two suspension rods 3 are also respectively located at the two ends of the fixed plate 2. Since a movable block 4 and a hook 5 are connected in sequence under one suspension rod 3, when there are two suspension rods, they are respectively connected with movable blocks 4 and hooks 5. In this way, after the two hooks 1 hook the crossbeam, the two hooks 5 under the two suspension rods hook the steel ropes on both sides of the rope wheel at the same time, and the two movable blocks 4 are rotated to make the two hooks 5 rise to lift the steel rope. At this time, the two hooks 5 only need to rise to a height that is not too high to lift the steel rope off the top of the rope wheel. In addition, another effect of this design is that when the auxiliary device is high enough, the maintenance personnel can directly place the auxiliary device across the crossbeam, the two hooks 5 hook the steel rope, and the movable block 4 is rotated to lift the steel rope.

[0037] In actual application, when the hook 5 just hooks the steel rope, the maintenance personnel can use their hands to rotate the movable block 4, but when the hook 5 and the steel rope are slowly tightened, it is necessary to use a tool such as a wrench to clamp the movable block 4 for rotation. Here, as a further improvement, the first inner cavity and the second inner cavity are designed to be horizontal through holes, and the two are connected, such as Figure 1 Horizontal through holes refer to Figure 1 In the orientation shown or in actual use, the axis of this hole is perpendicular to the vertical direction, and the hole passes through the movable block 4. Here, the shape of the hole is not limited. In this way, the maintenance personnel can use a wrench handle or other similar handles, steel bars, screwdrivers and other tools to insert into this space, and then rotate the movable block 4. It can be seen that this design allows the maintenance personnel to use more and wider tools when rotating the movable block 4.

[0038] In addition, after the maintenance personnel complete the replacement of the rope pulley or the rubber sleeve, they rotate the movable block 4 to lower the steel rope to make it return to the rope pulley. Here, in order to prevent the maintenance personnel from excessively rotating the movable block 4 and separating the hook 5 or the suspension rod 3 from the movable block 4, as a further improvement, Figure 1 As shown, a limiting ring is provided at one end of the suspension rod 3 close to the movable block 4 and / or one end of the straight portion 6 close to the movable block 4.
