Description

Technical Field

[0001] This invention relates to the field of coal mine cargo conveying equipment technology, specifically a lightweight slide and slide hoist. Background Technology

[0002] In coal mine cargo transportation, hoisting tracks and hoisting devices are core equipment. Due to the high dust concentration in coal mines, dust easily falls onto the limiting rails of the tracks and the surfaces of the hoisting pulleys, leading to: increased sliding resistance of the pulleys and higher energy consumption; and decreased friction during braking, posing safety hazards. Currently, dust removal mainly relies on manual cleaning using brushes and air guns, which generally suffers from the following problems: Impact on production efficiency: Requires machine downtime, reducing cargo transport efficiency; The cleaning process is difficult because the slide space is narrow and the lifting equipment is located inside the slide. It is difficult for workers to reach the hidden parts of the pulleys and limit rails. If necessary, the slide or lifting equipment can only be disassembled, which will increase the workload of workers. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide a lightweight slide rail with multiple drainage holes at the bottom of the slide rail. When the pulley slides in the slide rail, it will generate resonance, and most of the dust will be discharged from the drainage holes under the vibration. There is no need to stop the machine for manual intervention, which greatly reduces the difficulty of cleaning the slide rail and solves the problem of difficult dust cleaning in existing slide rails, which affects production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A lightweight slide, comprising a slide body arranged laterally; The core improvement is that a slide clearance groove extending along its length is provided in the middle of the bottom side of the slide body. The left and right sides of the slide clearance groove are symmetrical and recessed limiting slide rails. Multiple drain holes are linearly arrayed along the length of the limiting slide rails at the bottom.

[0005] By adopting the above solution, the lightweight slide rail has multiple drainage holes at the bottom of the limiting slide rail. When the pulley of the slide rail hanger slides in the slide rail, a certain resonance will be generated. Most of the dust will be discharged from the drainage holes under the vibration. There is no need to stop the machine for manual intervention to clean the dust, which greatly reduces the difficulty of cleaning the slide rail and solves the problem of difficult dust cleaning in existing slide rails, which affects production efficiency.

[0006] As a preferred embodiment of a lightweight slide, multiple perforations are arranged in a linear array along the length of the slide body on the left and right side walls to reduce the weight of the slide and achieve lightweighting.

[0007] As a preferred embodiment of a lightweight slide rail, the limiting slide rail is a V-shaped slide rail, which can enhance the guidance of the lifting device, and at the same time, allow the dust swept down to collect at the bottom of the slide rail, making it easy to discharge through the drain hole.

[0008] The second technical problem to be solved by the present invention is to provide a slide rail lifting device that triggers the dust cleaning wheel to clean the pulley simultaneously when transporting goods by suspending a heavy object, without the need for machine shutdown and manual intervention, which greatly reduces the difficulty of cleaning the lifting device and solves the problem of difficult dust cleaning on the pulley of existing lifting devices, which affects production efficiency.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A sliding track lifting device is slidably installed in a lightweight sliding track, including a vertically arranged lifting device body, two sets of coaxially arranged front pulleys that slide along a limiting slide rail are rotatably installed at the front end of the lifting device body, two sets of coaxially arranged rear pulleys that slide along a limiting slide rail are rotatably installed at the rear end of the lifting device body, and a hanging lifting rod is installed at the bottom of the lifting device body. The core improvement is as follows: the main body of the lifting device has two lifting device clearance slots located between the front pulley and the rear pulley. Each lifting device clearance slot has a vertically arranged sliding rod. A sliding seat is slidably installed on both sliding rods. Each sliding rod is fitted with a spring that pushes the sliding seat upward. Two sets of coaxial cleaning wheels (brush wheels) are fixed at the left and right ends of the sliding seat. A dangling traction rope is connected to the middle of the bottom of the slide block 1, and a hook is connected to the lower end of the traction rope 1. When no weight is suspended on hook one, the sweeping wheel does not rub against the front and rear pulleys; when a weight is suspended on hook one, the sweeping wheel rubs against both the front and rear pulleys simultaneously.

[0010] By adopting the above solution, when the main body of the lifting device is suspended without load, i.e., when hook 1 is not loaded with any weight, spring 1 lifts slide 1, and the sweeping wheel separates from the front and rear pulleys. At this time, the dust removal mechanism does not work. When the main body of the lifting device is suspended with a heavy load, the weight of the load pulls slide 1 downward through traction rope 1, compressing spring 1. The sweeping wheel contacts the front and rear pulleys simultaneously, cleaning the dust on the wheel wall. There is no need to stop the machine for manual dust removal, which greatly reduces the difficulty of cleaning the lifting device and solves the problem of difficult dust removal on existing lifting device pulleys, which affects production efficiency.

[0011] As a preferred embodiment of the sliding track lifting device, a second lifting device clearance groove extending towards the location of the lifting rod is provided on the rear side of the lifting device body, wherein the first traction rope and the first hook are located in the second lifting device clearance groove to avoid interfering with the sliding of the lifting device.

[0012] The third technical problem to be solved by the present invention is to provide a slide rail lifting device that triggers the dust cleaning wheel to simultaneously clean the dust on the slide rail surface when transporting goods by suspending a heavy object, without the need for machine shutdown and manual intervention, which greatly reduces the difficulty of cleaning the slide rail and further solves the problem of the difficulty of cleaning dust in the existing slide rail and the impact on production efficiency.

[0013] To achieve the above objectives, the present invention provides the following technical solution: Based on the above scheme, a horizontally arranged and forward-extending base is connected to the front end of the lifting device body. Two vertically arranged sliding rods are fixed on the base. Slide seats are slidably installed on the two sliding rods. Each sliding rod is fitted with a spring that pushes the slide seat upward. The slide seat is connected to a cleaning strip (V-shaped soft rubber strip) that is attached to the inner wall of the limiting slide rail through two downward-extending connecting rods. A dangling traction rope is connected to the middle of the bottom of the slide block two, and a hook is connected to the lower end of the traction rope two. When no heavy object is suspended on hook two, the cleaning strip is not in contact with the limit rail; when a heavy object is suspended on hook two, the cleaning strip is in contact with the limit rail.

[0014] By adopting the above solution, when the main body of the lifting device is unloaded, i.e., when hook two is not loaded, spring two lifts slide two, and the cleaning strip separates from the limit slide rail. At this time, the dust removal mechanism does not work. When the main body of the lifting device is loaded with a heavy object, the weight of the object pulls slide two downward through traction rope two, compressing spring two. The cleaning strip contacts the inner wall of the limit slide rail, accelerating the dust to fall from the drain hole. There is no need to stop the machine for manual intervention to clean the dust, which greatly reduces the difficulty of cleaning the slide and solves the problem of difficult dust cleaning in the existing slide, which affects production efficiency.

[0015] As a preferred embodiment of the slide rail hanger, the cleaning strip is also fixed with a guide plate that extends in an arc towards the slide rail clearance groove. When there is a lot of dust in the limiting slide rail and it cannot be completely discharged from the drain hole, the guide plate can guide the dust to be discharged from the slide rail clearance groove.

[0016] As a preferred embodiment of the sliding track lifting device, a lifting device clearance groove three is provided on the front side of the lifting device body, extending towards the location of the lifting rod, wherein the traction rope two and the hook two are located in the lifting device clearance groove three to avoid interfering with the sliding of the lifting device.

[0017] The beneficial effects of this invention are: 1. Automatic dust removal of the slide rail: This lightweight slide rail has multiple drainage holes at the bottom of the limit rail. When the pulley of the slide rail hanger slides in the rail, it will generate a certain resonance. Most of the dust will be discharged from the drainage holes under the vibration. There is no need to stop the machine for manual dust removal, which greatly reduces the difficulty of cleaning the slide rail and solves the problem of difficult dust removal in existing slide rails, which affects production efficiency. 2. Convenient dust collection: The drain hole and slide rail clearance groove at the bottom of the limit slide rail can concentrate and discharge dust, avoiding secondary accumulation; 3. Automatic dust removal from pulleys: The dust removal wheel is triggered by suspending a heavy object to clean the pulleys simultaneously while transporting goods. No manual intervention or machine stoppage is required, which greatly reduces the difficulty of cleaning the lifting equipment and solves the problem of difficult dust removal from existing lifting equipment pulleys, which affects production efficiency. 4. Further dust removal from the slide rail: By suspending a heavy object, the dust removal wheel is triggered to simultaneously clean the dust on the surface of the slide rail while transporting goods. This eliminates the need for machine shutdown and manual intervention, greatly reducing the difficulty of cleaning the slide rail and further solving the problem of difficult dust removal in the existing slide rail, which affects production efficiency.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0022] Example 1, as Figures 1 to 2 As shown, a lightweight slide is provided for transporting goods in coal mine roadways. The lightweight slide 1 includes a slide body 11 arranged laterally. A slide clearance groove 12 extending along its length is provided in the middle of the bottom side of the slide body 11. The left and right sides of the slide clearance groove 12 are mutually symmetrical and sunken limiting slide rails 13. Multiple drainage holes 14 linearly arrayed along the length of the limiting slide rails 13 are provided at the bottom. Because multiple drainage holes 14 are provided at the bottom of the limiting slide rails 13, the pulleys of the slide hoist 2 will generate a certain resonance when sliding in the slide rail. Most of the dust will be discharged from the drainage holes 14 under the vibration, eliminating the need for manual intervention to clean the dust. This greatly reduces the difficulty of cleaning the slide and solves the problem of difficult dust cleaning and reduced production efficiency in existing slides.

[0023] like Figure 2 As shown, multiple perforations 15 are arranged linearly along the length of the slide body 11 on the left and right side walls to reduce the weight of the slide and achieve lightweighting.

[0024] Continue as Figure 2 As shown, the limiting slide rail 13 is a V-shaped slide rail, which can enhance the guidance of the lifting device, and at the same time, the dust swept down can be collected at the bottom of the slide rail, making it easy to be discharged through the drain hole 14.

[0025] like Figures 3 to 4As shown, a slide rail hanger is provided, which is slidably installed in a lightweight slide rail 1. The slide rail hanger 2 includes a vertically arranged hanger body 21. Two sets of coaxially arranged front pulleys 22 are rotatably installed at the front end of the hanger body 21 and slide along the limiting slide rail 13. Two sets of coaxially arranged rear pulleys 23 are rotatably installed at the rear end of the hanger body 21 and slide along the limiting slide rail 13. A hanging rod 24 is installed at the bottom of the hanger body 21 by a nut.

[0026] like Figures 4 to 5 As shown, the main body 21 of the lifting device has two lifting device clearance slots 25 located between the front pulley 22 and the rear pulley 23. Each lifting device clearance slot 25 has a vertically arranged sliding rod 26 welded and fixed in it. Sliding seats 27 are slidably installed on the two sliding rods 26. Each sliding rod 26 is fitted with a spring 28 that pushes the sliding seat 27 upward. Two sets of coaxial cleaning wheels 29 (brush wheels) are welded and fixed to the left and right ends of the sliding seat 27.

[0027] like Figure 5 As shown, a dangling traction rope 210 (non-elastic rope) is tied to the middle of the bottom of the slide block 27, and a hook 211 is tied to the lower end of the traction rope 210. When no weight is suspended on the hook 211, the sweeping wheel 29 does not rub against the front pulley 22 and the rear pulley 23. When a weight is suspended on the hook 211, the sweeping wheel 29 rubs against the front pulley 22 and the rear pulley 23 at the same time.

[0028] Continue as Figure 5 As shown, a second lifting device clearance groove 212 extending towards the location of the lifting rod 24 is provided on the rear side of the lifting device body 21. The first traction rope 210 and the first hook 211 are located in the second lifting device clearance groove 212 to avoid interfering with the sliding of the lifting device.

[0029] Working principle of Example 1: When the lifting device body 21 is suspended without load, i.e., the hook 211 is not loaded with any weight, the spring 28 lifts the slide 27, and the sweeping wheel 29 separates from the front pulley 22 and the rear pulley 23. At this time, the dust removal mechanism does not work. Figure 5 As shown; when the lifting device body 21 suspends a heavy object, the weight of the heavy object pulls the slide block 27 downward through the traction rope 210, compressing the spring 28. The cleaning wheel 29 contacts the front pulley 22 and the rear pulley 23 at the same time. The dust on the wall of the cleaning wheel 29 can be cleaned without stopping the machine for manual intervention, which greatly reduces the difficulty of cleaning the lifting device.

[0030] Example 2, as Figures 6 to 8As shown, the difference between this embodiment and Embodiment 1 is only that, based on Embodiment 1, a horizontally arranged and forward-extending base 213 is welded to the front end of the lifting device body 21. Two vertically arranged sliding rods 214 are welded and fixed on the base 213. Slide seats 215 are slidably installed on the two sliding rods 214. Each sliding rod 214 is fitted with a spring 216 that pushes the slide seat 215 upward. The slide seat 215 is connected to a cleaning strip 217 (V-shaped soft rubber strip) that is attached to the inner wall of the limiting slide rail 13 through two downward-extending connecting rods 218.

[0031] like Figure 8 As shown, a dangling traction rope 220 (non-elastic rope) is tied to the middle of the bottom of the slide block 215. The lower end of the traction rope 220 is tied to a hook 221. When no weight is suspended on the hook 221, the cleaning strip 217 is not in contact with the limit rail 13. When a weight is suspended on the hook 221, the cleaning strip 217 is in contact with the limit rail 13.

[0032] like Figures 7 to 8 As shown, a guide plate 219 extending in an arc shape towards the slide rail clearance groove 12 is also fixed on the cleaning strip 217. When there is a lot of dust in the limiting slide rail 13 and it cannot be completely discharged from the drain hole 14, the guide plate 219 can guide the dust to be discharged from the slide rail clearance groove 12.

[0033] like Figure 8 As shown, a lifting device clearance groove 222 extending towards the location of the lifting rod 24 is provided on the front side of the lifting device body 21. The traction rope 220 and the hook 221 are located in the lifting device clearance groove 222 to avoid interfering with the sliding of the lifting device.

[0034] Working principle of Example 2: When the main body 21 of the lifting device is unloaded, that is, when the hook 221 is not loaded, the spring 216 lifts the slide 215, and the cleaning strip 217 separates from the limit slide rail 13. At this time, the dust removal mechanism does not work. When the main body 21 of the lifting device is loaded with a heavy object, the weight of the heavy object pulls the slide 215 downward through the traction rope 220, compressing the spring 216. The cleaning strip 217 contacts the inner wall of the limit slide rail 13, accelerating the dust to fall from the drain hole 14. There is no need to stop the machine for manual intervention to clean the dust, which greatly reduces the difficulty of cleaning the slide and solves the problem of difficult dust cleaning in the existing slide, which affects production efficiency.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
