Description

Technical Field

[0001] This utility model relates to the field of fully mechanized mining equipment installation technology, specifically to a winch moving and fixing device in the conveyor chute. Background Technology

[0002] The geological conditions in the Huainan mining area are complex. When installing hydraulic supports in the fully mechanized mining face, it is often necessary to use a winch to drag and pull the supports. The winch is positioned on the chute of the already installed scraper conveyor 4'. As the supports are installed, the winch needs to be moved continuously.

[0003] Currently, when using a diesel-powered monorail for transportation, the normal installation sequence is to first install the chute, and then install the support frame after the chute is in place. Figure 1 As shown, when the bracket 5' to be installed is transported to the vicinity of the installation position, the bracket head faces the already installed bracket 1'. If the bracket needs to be adjusted, a slow winch must be installed in the already installed scraper conveyor chute, such as... Figure 1 The #4 winch 7' pulls the head of the support frame 5' to be installed via the second pulley 6'. Combined with the traction from the tail pulley 2' and the #3 winch 3', it adjusts the support frame 5' into position. The #4 winch 7' has no other installation location. As the support frame is installed, the #4 winch 7' needs to be continuously moved towards the installation direction of the support frame to reduce the distance between the winch and the installation position. The winch used to pull the support frame is typically a return winch or a dual-speed winch.

[0004] However, the existing methods for moving winches in chutes are as follows: one method is to fix the wire rope end of the winch, then start the winch to wind up the rope and move the winch forward. This requires the winch cable and switch to move forward with the winch, and the winch operator to move forward with the winch while holding the start button. However, coal mine safety regulations stipulate that cables and switches are not allowed to be moved while energized. If the cable is scraped, it is easy to get an electric shock.

[0005] Method two involves positioning another winch at the front end of the pulling direction and using that winch to pull the main winch. Both methods have drawbacks. First, if the chute is not installed straight and is tilted, the winch may occasionally fall off the coal wall sidewall during the pulling process, scraping against the chute and sidewall. In this case, a hand-operated hoist is needed to lift the winch back onto the chute before pulling, which is inefficient, time-consuming, and labor-intensive. Second, if the working face has an inclination and the chute is on a slope, there is a risk of the winch sliding downwards when pulling. A rope must be left in place during the pulling process, requiring the use of another winch or a hand-operated hoist behind the main winch for rope placement, which is complex and inefficient. Furthermore, when using another winch to pull the main winch, the upstream power supply to the main winch must be shut off and locked.

[0006] Furthermore, existing fixing methods use anchor chains, which require removing the anchor chains after each winch movement and then re-fixing them after positioning, which is time-consuming and labor-intensive. Therefore, this application addresses these shortcomings by proposing a winch movement and fixing device within the conveyor chute. Utility Model Content

[0007] The technical problem to be solved by this utility model is: how to solve the problem of low efficiency in the movement of winches on the conveyor chute.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A winch moving and fixing device in a conveyor chute includes a central chute of the conveyor, a base slidably connected above the central chute, a winch mounted on the base, one side of the base connected to a chute rail on the central chute, a fixed slider slidably connected on the chute rail, and a hydraulic pushing mechanism for connecting the fixed slider is also provided on the chute rail.

[0010] This application solves the problems of winch fixing and moving by adding a base, mounting the winch on the base, and using the chute on the conveyor as a slide rail to cooperate with the base. A hydraulic pushing mechanism allows the base to move along the chute in a step-by-step manner. After each support is installed, the winch is moved forward by one winch length. Remote hydraulic operation is used, which is safe, reliable, efficient, and simple. Compared with traditional methods, it reduces construction steps, lowers the labor intensity of workers, and simplifies operation.

[0011] As a further embodiment of this utility model: the fixed slider includes a base fixed slider one and a base fixed slider two, wherein the base fixed slider one and the base fixed slider two are slidably connected to the slide rail.

[0012] As a further embodiment of this utility model: the hydraulic pushing mechanism includes a pushing hydraulic cylinder and a pushing fixed slider, wherein the pushing fixed slider is slidably connected to the slide rail, one end of the pushing hydraulic cylinder is connected to the pushing fixed slider, and the other end is connected to the base fixed slider.

[0013] As a further embodiment of this utility model, the base is detachably mounted to the winch via a hinge.

[0014] As a further embodiment of this utility model: the bottom ends of the base are slidably attached to the sides of the trough in the middle of the transport machine.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This application solves the problems of winch fixing and moving by adding a base, mounting the winch on the base, and using the chute on the conveyor as a slide rail to cooperate with the base. A hydraulic pushing mechanism allows the base to move along the chute in a step-by-step manner. After each support is installed, the winch is moved forward by one winch length. Remote hydraulic operation is used, which is safe, reliable, efficient, and simple. Compared with traditional methods, it reduces construction steps, lowers the labor intensity of workers, and simplifies operation. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 2 , Figure 3 and Figure 4A winch moving and fixing device in a conveyor chute includes a conveyor middle chute 1, a base 3, a base fixing slider 1 4, a base fixing slider 2 5, a pushing hydraulic cylinder 6, and a pushing fixing slider 7. The base 3 is installed above the conveyor middle chute 1 and can be slidably installed on the chute side of the conveyor middle chute 1 and can slide along the chute side of the conveyor middle chute 1.

[0026] Reference Figure 2 , Figure 3 and Figure 4 The chute pin rail 2 is part of the middle trough 1 of the conveyor and is located on one side of the middle trough 1 of the conveyor. One side of the base 3 is connected to the base fixing slider 1 4 and the base fixing slider 2 5. The base fixing slider 1 4 and the base fixing slider 2 5 can hold the outside of the chute pin 2 and slide along the chute pin 2. The #4 winch 7' can be detachably installed on the base 3 by a hinge. Therefore, when the base fixing slider 1 4 and the base fixing slider 2 5 move along the chute pin rail 2, the base 3 can also move along the chute pin rail 2, and the #4 winch 7' on the base 3 will also move, so that the #4 winch 7' can move along the chute pin 2.

[0027] Reference Figure 2 , Figure 3 and Figure 4 A sliding fixed slider 7 is also provided on the slide rail 2 and behind the base fixed slider 4. The sliding fixed slider 7 can slide on the slide rail 2, and a sliding hydraulic cylinder 6 is installed on the sliding fixed slider 7. The sliding hydraulic cylinder 6 can push the base fixed slider 4 to move on the slide rail 2, and the base fixed slider 5 will also move on the slide rail 2, thereby realizing the movement of the base 3 and the 4# winch 7' on it. The sliding hydraulic cylinder 6 can be remotely operated. Structurally, the conveyor (scraper conveyor) chute rail is used as the slide, and the base is not limited by the chute side. The hydraulic system uses hydraulic cylinders as the actuators to achieve step-by-step movement. The hydraulic cylinders are remotely supplied with fluid, and the movement is carried out in a step-by-step manner. After each support is installed, the winch is moved forward by one winch distance.

[0028] Reference Figure 1 and Figure 2 , Figure 1The diagram shows the installation of the bracket to be installed by the winch 7'. When the winch 7' is moved along the slide pin 2 on the middle groove 1 of the conveyor by the base 3, the base fixing slider 1 4 and the base fixing slider 2 5, it can pass through the chain to the second pulley 6' and then pull the head of the bracket to be installed 5'. With the traction of the tail first pulley 2' and the winch 3', the bracket to be installed 5' is adjusted into position. As the bracket is installed, the winch 7' needs to move continuously in the installation direction of the bracket in order to reduce the distance between the winch and the bracket installation position.

[0029] This device has been applied to the 14158 installation face of Zhangji Mine with good results; it solves the problems of winch fixing and pulling, uses remote hydraulic operation, is safe and reliable, highly efficient, and has a simple process; compared with traditional processes, it reduces construction steps, reduces the labor intensity of workers, and is easy to operate.

[0030] The specific operating principle of this application is as follows:

[0031] The base 3 is slidably installed on the middle trough 1 of the conveyor, and the base fixing slider 1 4 and the base fixing slider 2 5 on one side of the base 3 are slidably attached to the chute pin rail 2 of the conveyor. The #4 winch is installed on the base 3. The #4 winch can move with the base 3 on the conveyor. Then, the push hydraulic cylinder 6 is controlled to push the base fixing slider 1 4 to move on the chute pin rail 2, and the base fixing slider 2 5 will also move on the chute pin rail 2, thereby realizing the movement of the base 3 and the #4 winch 7' on it. The push hydraulic cylinder 6 can realize remote control operation. Structurally, the chute pin rail of the conveyor (scraper conveyor) is used as the slide, and the base 3 slides in contact with the trough side of the middle trough.

[0032] After winch #4 is in place at 7', proceed with the installation of the support frame, such as... Figure 1 As shown, when the support frame 5' to be installed is transported to the vicinity of the installation position, its head faces the already installed support frame 1'. When it is necessary to adjust the direction of the support frame, winch #4 pulls the head of the support frame through the second pulley 6', and then works with the first pulley 2' and winch #3' to pull the tail end, adjusting the support frame into position. Winch #4 has no other installation location. As the support frame is installed, winch #4 needs to be continuously moved in the direction of the support frame installation to reduce the distance between the winch and the support frame installation position, reduce the distance of the manual winch wire rope, and reduce labor intensity. The winch used to pull the support frame is basically a column return winch or a dual-speed winch.
