Description

Technical Field

[0001] This utility model belongs to the technical field of mining auxiliary devices, specifically relating to a lifting device for installing chute boxes in mine roadways. Background Technology

[0002] In mine roadways, it is often necessary to install cylindrical troughs made of iron or other metals in the ore pass. The traditional installation method requires first assembling multiple curved metal pieces into a cylindrical shape, then building scaffolding from the bottom of the ore pass to transport the cylindrical trough section by section to the installation location, and then installing them one by one. The entire installation process is very cumbersome. Moreover, due to the narrow space in the ore pass, ordinary lifting devices cannot be used, so the upward transportation of the cylindrical trough relies entirely on manual handling and lifting, which is labor-intensive and has high safety risks. Utility Model Content

[0003] In response to the problems existing in the prior art, and after analyzing the installation process of the chute box, this utility model designs a lifting device for the installation of chute boxes in mine roadways. It can be installed in the chute inside the roadway, and the assembled cylinders can be transported upwards in sequence for installation, avoiding manual lifting, reducing labor intensity and improving work efficiency.

[0004] This utility model specifically includes the following:

[0005] A lifting device for installing a mine chute in a mine roadway includes at least two sets of separately configured lifting systems. The at least two sets of lifting systems are evenly distributed along the circumference of the chute to ensure balance during the lifting process and prevent tilting.

[0006] The lifting system includes a base, a lifting mechanism, a limiting mechanism, and a clamping mechanism.

[0007] The base includes a front and a back. The back of the base is provided with at least two rollers. When it is necessary to move the object, it can be tilted backward and then the base can be pushed to rotate the rollers, which can achieve the movement in a time-saving and labor-saving manner.

[0008] The lifting mechanism includes a support frame, a lifting power mechanism, a transmission mechanism, a lifting connection mechanism, and a control device. The support frame is disposed above the base. The lifting connection mechanism is disposed above the front of the base and is slidably connected to the support frame. The lifting connection mechanism is connected to the lifting power mechanism through the transmission mechanism. The control device is connected to the lifting power mechanism. The lifting mechanism can automatically lift and lower in the vertical direction, and in conjunction with the clamping mechanism, realize the lifting and installation of the chute box cylinder.

[0009] The limiting mechanism is located at the top of the support frame and is used to limit the sliding of the lifting connection mechanism at the upper end of the support frame.

[0010] The clamping mechanism includes a connecting end and a clamping end. The connecting end is connected to the lifting connecting mechanism. The clamping end includes an upper arc-shaped clamping piece and a lower arc-shaped clamping piece, which are respectively connected to the connecting end to form an arc-shaped mounting clamp. The opening refers to the side of the mounting clamp facing the chute box body. This side is set in an arc shape, and the specific arc and diameter can be adjusted according to the diameter of the chute box body to be transported. This allows the mounting clamp to fit more closely to the chute box body, making the clamping more stable and preventing accidents such as slippage during lifting, thus making it safer and more reliable.

[0011] Furthermore, the lower arc-shaped clamping piece is fixedly connected to the connecting end; the upper arc-shaped clamping piece is rotatably connected to the connecting end (e.g., via a pin). Further, it includes at least one set of clamping and fixing bolts and nuts. At least one set of fixing holes is provided on the upper and lower arc-shaped clamping pieces. The clamping and fixing bolts are disposed in the fixing holes, and the nuts are fitted onto the threaded end of the clamping and fixing bolts. The rotatable connection between the upper arc-shaped clamping piece and the connecting end can accommodate objects of different thicknesses and allows for flexible adjustment of the clamping tightness. The clamping and fixing bolts and nuts secure the upper and lower arc-shaped clamping pieces, making the clamping more robust, preventing loosening during lifting, and ensuring greater safety and reliability.

[0012] Furthermore, the lifting power mechanism includes a battery and a motor connected to the battery; the transmission mechanism includes two sets of transmission gears respectively disposed at the upper and lower ends of the support frame and a transmission rack ring meshing with the two sets of gears, the two sets of transmission gears or one of the transmission gears being connected to the motor; the lifting connection mechanism is connected to the transmission rack ring.

[0013] Furthermore, the lifting system also includes two sets of jacks, which are located at the bottom of the base and are used to support the base between the tunnels.

[0014] Furthermore, a sensing device is also provided on the upper end of the support frame or the lower surface of the limiting mechanism, and the sensing device is connected to the control device. When the sensing device detects that the lifting connecting mechanism, clamping mechanism, or the object being lifted has reached its highest point, it promptly transmits a sensing signal to the control device, which then controls the motor to automatically stop working, thereby achieving automatic control of lifting. The sensing device can be an existing sensing device such as an infrared sensor, as long as it can achieve position sensing.
