Description

Technical Field

[0001] This invention relates to the field of coal mine tunnel engineering technology, and in particular to a method for rapid installation of a monorail track. Background Technology

[0002] With the rapid popularization of monorail continuous transportation in coal mines, underground mining area transportation has gradually shifted from ground rail transportation to diesel engine monorail transportation. During the installation and dismantling of fully mechanized mining faces, the transportation of large equipment has also gradually shifted to monorail transportation. Therefore, the quality and speed of monorail track installation are becoming increasingly important, directly affecting the transportation efficiency of mining areas and working faces.

[0003] In the past, the installation of monorail tracks was carried out by high-altitude assembly. For example, the patent document with publication number CN113602963A disclosed a monorail installation method in which the monorail track beam is suspended from the top of the tunnel by a circular chain connected to the suspension lug. The existing monorail track installation method has the following defects: (1) When installing the monorail track beam, two people need to stand on two scaffolds respectively to lift the two adjacent monorail track beams to the installation height and then connect them end to end and suspend them to the top of the tunnel by a circular chain. After the connection is completed, the two people will lift the two scaffolds to the next connection position to install the two adjacent monorail track beams. The labor intensity is high, the work efficiency is low, and the safety is low; (2) When installing the monorail track beam, the existing lifting point positioning tools are not professional and the positioning error is large. It is easy to cause rework due to unsuitable lifting points. Summary of the Invention

[0004] The technical problem to be solved by this invention is how to reduce the labor intensity of monorail installation and improve work efficiency and safety.

[0005] This invention solves the above-mentioned technical problems through the following technical means: a method for rapid installation of a monorail track, comprising the following steps:

[0006] Step 1: Install the hanging anchor bolts;

[0007] Step 2: Install the suspension chain on each suspension anchor rod;

[0008] Step 3: Assemble multiple monorail tracks together on the ground and install the hanging components;

[0009] Step four: Use a lifting device to lift the assembled monorail tracks together.

[0010] Step 5: Adjust the monorail track to the required height and connect the suspension components to the corresponding suspension chains.

[0011] This invention changes the assembly method of monorail tracks from high-altitude assembly to ground assembly. After multiple monorail tracks are assembled on the ground, they are lifted together by a lifting device. Manual work at height only requires connecting the hanging parts and the hanging chain, which reduces the labor intensity of monorail track installation and improves work efficiency and safety.

[0012] As an optimized technical solution, in step one, holes are made in the top plate using a hole-making device, and then hanging anchor rods are installed at each hole location.

[0013] The dotting device includes a paint sprayer, a positioning mechanism, a paint outlet tube, a pressing rod, a plumb line, and a steel tape measure. The paint sprayer removes the original nozzle. The positioning mechanism is fixedly connected to the paint sprayer and is fitted over the outside of the paint sprayer nozzle. The paint outlet tube can be inserted into the positioning mechanism, and one end inserted into the positioning mechanism can contact the end of the paint sprayer nozzle. One end of the pressing rod and one end of the plumb line are both fixedly connected to the paint sprayer.

[0014] The method for applying dots to the ceiling using a dotting device is as follows: First, straighten and lay a steel tape measure flat on the base plate and fix it in place, determining the corresponding measurement value for each dotting position. Then, insert the paint tube into the positioning mechanism, attach a weight to the end of the plumb line away from the paint spraying end, and hold the pressing rod to bring the paint tube into contact with the ceiling plate, aligning the plumb line with the steel tape measurement value corresponding to the first dotting position. Then, use the pressing rod to press the paint upwards, at which point the paint tube presses down the paint nozzle, and the paint is sprayed through the paint tube onto the ceiling plate, completing the dotting of the first dotting position. Repeat this method to dot each dotting position in sequence.

[0015] The eye-dotting device can achieve precise eye-dotting, eliminating the error of the lifting point positioning and avoiding rework caused by unsuitable lifting points.

[0016] As an optimized technical solution, the positioning mechanism includes a fixing ring, a connecting rod, and a positioning tube. The fixing ring is sleeved around the outer periphery of the paint sprayer and fixedly connected to it. The positioning tube is coaxially disposed inside the fixing ring and fixedly connected to it via the connecting rod. The positioning tube is sleeved around the outside of the paint sprayer nozzle. This positioning mechanism protects the nozzle, preventing damage during the application process and enabling the application of the paint in one operation.

[0017] As an optimized technical solution, the eye-dotting device also includes a drain rod, which can be inserted into the paint outlet tube. After eye-dotting is completed, the drain rod can be used to clean the paint outlet tube for easy next use.

[0018] As an optimized technical solution, the dotting device includes multiple paint outlet tubes of different lengths. The appropriate length of paint outlet tube can be selected based on the condition of the ceiling.

[0019] As an optimized technical solution, in step five, the installer uses a track adjustment device on the ground to adjust the monorail to the required height, while another installer climbs up to connect the hanging component to the corresponding hanging chain.

[0020] The track adjustment device includes a lifting mechanism, a length adjustment mechanism, and a snap-fit ​​component. One end of the length adjustment mechanism is fixedly connected to the lifting end of the lifting mechanism, and the other end of the length adjustment mechanism is fixedly connected to the snap-fit ​​component.

[0021] The method for adjusting the monorail to the required height using the track adjustment device is as follows: First, adjust the length of the length adjustment mechanism according to the required height of the track installation and the height of the lifting end of the lifting mechanism at the highest position. After adjustment, maintain the length of the length adjustment mechanism. Adjust the position of the lifting end of the lifting mechanism to make the locking piece lock the lower part of the monorail. Then, adjust the lifting end of the lifting mechanism to the highest position to raise the monorail to the required height.

[0022] The track adjustment device can quickly adjust the track height on the ground, keeping the monorail track straight, further reducing the labor intensity of manual climbing operations and improving work efficiency and safety.

[0023] As an optimized technical solution, the length adjustment mechanism includes a first adjustment tube, a second adjustment tube, and a connecting pin. Both the first adjustment tube and the second adjustment tube have a connecting hole at regular intervals along the length direction. The second adjustment tube is inserted into the first adjustment tube and is fixedly connected to the first adjustment tube by the connecting pin passing through two corresponding connecting holes on the first adjustment tube and the second adjustment tube.

[0024] As an optimized technical solution, the specific method for installing the suspension chain in step two is as follows: first, remove the nut of the suspension anchor rod, then install the U-shaped lifting ring on the suspension anchor rod, and then install the suspension chain on the U-shaped lifting ring.

[0025] As an optimized technical solution, in step three, the specific method for assembling the monorail tracks on the ground is as follows: First, connect the lower parts of the first monorail track and the second monorail track through the lower connector. Then, connect the upper parts of the first monorail track and the second monorail track through the upper connector. Then, install the hanging parts on the upper connector. Assemble each monorail track in sequence according to this method.

[0026] As an optimized technical solution, the lifting device uses two hand-operated hoists, which are respectively installed on the lifting rings on the top plate. The chains of the two hand-operated hoists are respectively connected to two hanging parts at both ends of the length direction on multiple monorail tracks assembled together.

[0027] The advantages of this invention are:

[0028] 1. This invention changes the assembly method of monorail tracks from high-altitude assembly to ground assembly. Multiple monorail tracks are assembled on the ground and then lifted together for hanging. Manual work at height only requires connecting the hanging parts and the hanging chain, which reduces the labor intensity of monorail track installation and improves work efficiency and safety.

[0029] 2. The dotting device can achieve precise dotting, eliminate the positioning error of the lifting point, and avoid rework caused by unsuitable lifting points; the positioning mechanism can protect the nozzle and prevent the nozzle from being damaged during the dotting process, so as to complete the dotting operation in one go.

[0030] 3. The track adjustment device can quickly adjust the track height on the ground, keeping the monorail track straight, further reducing the labor intensity of manual climbing operations and improving work efficiency and safety. Attached Figure Description
