Description

Technical Field

[0001] The utility model relates to a high-altitude docking device for a shaft horse head door, specifically an ultra-deep and large-diameter

[0002] The shaft gantry high-altitude docking device is primarily used to connect the hoist bucket to the existing gantry during shaft sinking. Ultra-deep and large-diameter typically refers to depths greater than 1200 meters and diameters greater than 10.5 meters. Background Art

[0003] In recent years, non-coal mining areas have been continuously shifting downward. Deep shaft construction is an effective way to achieve safe and efficient mining of deep resources. Currently, there are 55 vertical shafts exceeding one kilometer in the coal industry, and 45 metal and non-metal mines are under construction or planned to have shafts exceeding 1,000 meters in depth. The construction of ultra-deep and large-diameter shafts presents difficulties and challenges in shaft construction. For example, the auxiliary shaft project of the Sanshandao Gold Mine, with a depth of 1,915 meters and a diameter of 10.5 meters, is the deepest shaft currently under construction in Asia.

[0004] The high-altitude docking device for the gantry gate is a crucial component in achieving temporary multi-stage drainage during shaft excavation. To facilitate maintenance, access, and material and equipment transportation, construction personnel must access the high-altitude gantry gate via a bucket. Because the closest distance between the bucket edge and the gantry gate in large-diameter shafts is greater than 1.7 meters, a practical, safe, and reliable high-altitude docking device is required for shaft construction and personnel safety.

[0005] As a conventional high-altitude docking device for the spur gate during shaft sinking, due to the small cross-section of the shaft, a horizontal brace or drawbridge platform is typically erected at the edge of the spur gate. When the bucket reaches this position mid-air and its upper end is parallel to it, personnel and supplies enter the spur gate via the horizontal brace or drawbridge. This system has several major drawbacks: first, the high-altitude crossing can easily lead to accidents such as personnel slipping and falling into the well; second, it hinders platform maintenance; and third, the drawbridge platform requires dedicated personnel at the spur gate to raise and lower the drawbridge, resulting in a high failure rate. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a high-altitude docking device for an ultra-deep and large-diameter shaft horsehead door, so as to realize the safe passage of personnel, materials and equipment between the bucket and the horsehead door.

[0007] The technical solution of the utility model is as follows:

[0008] An ultra-deep, large-diameter shaft horsehead gate high-altitude docking device comprises a shaft and a horsehead gate opened on one side of the shaft and communicating with the shaft, a bucket being suspended in the shaft, and the docking device further comprising a channel steel track laid on the bottom plate of the horsehead gate and a docking platform running along the channel steel track; the docking platform rollingly cooperates with the channel steel track through rollers installed on the bottom side and can partially penetrate into the shaft, and its probing end is used for overlapping with the bucket.

[0009] Preferably, the docking platform is hinged with a folding plate for overlapping with the bucket.

[0010] Preferably, the docking device also includes a steel wire rope with one end suspended on the rock wall of the horse head gate and the other end having a ring buckle and used to connect to the operator's safety belt hook.

[0011] Preferably, the docking device further includes a docking platform non-return device; the docking platform non-return device includes a non-return hole provided on the channel steel rail and a non-return rod for penetrating into the non-return hole.

[0012] Preferably, guardrails are installed on the sides of the docking platform.

[0013] The positive effects of this utility model are:

[0014] First, the utility model features a docking platform that can partially penetrate the shaft. The platform's protruding end connects to the bucket, enabling safe passage and transportation of personnel, materials, and equipment between the bucket and the horsehead gate. The four-meter-long docking platform enables safe and reliable docking of the bucket and horsehead gate at a height of 1.797 meters.

[0015] Second, the operator's wire rope suspension safety belt ensures that the operator always remains reliably and safely fixed when entering and exiting the bucket, walking on the platform, and working near the horse head door.

[0016] Third, a non-return device is installed to prevent the platform from moving forward and backward. This ensures that the platform does not slide in the underground water, high temperature and high humidity environment, and avoids falling from a height due to slippage.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] like Figure 1 and Figure 2 An embodiment of the present invention provides an ultra-deep, large-diameter shaft horsehead gate high-altitude docking device, comprising a shaft 1 and a horsehead gate 3 disposed on one side of the shaft 1 and communicating with the shaft 1. A bucket 7 is suspended within the shaft 1. This embodiment also includes a channel steel track 4 laid on the bottom plate of the horsehead gate 3 and a docking platform 5 that runs along the channel steel track 4. The docking platform 5 rolls with the channel steel track 4 via rollers 8 mounted on its underside and is capable of partially protruding into the shaft 1, with its protruding end configured to engage with the bucket 7.

[0022] Furthermore, the front end of the docking platform 5 (i.e., the end for overlapping the bucket 7) is hinged with a folding plate 6 for overlapping the upper side of the bucket wall of the bucket 7. The folding plate 6 is overlapped on the upper side of the bucket wall of the bucket 7 by flipping or retracted to the docking platform 5 by flipping in the opposite direction.

[0023] Further, the present embodiment also comprises one end being suspended on the rock wall of the horse head gate 3, and the other end having a steel wire rope 2 with an annular buckle. The described other end of this steel wire rope 2 is used to connect the operator's safety belt hook.

[0024] Furthermore, this embodiment includes a docking platform anti-return device. This device comprises a anti-return hole 9 defined in the channel rail 4 and a anti-return rod 10 inserted into the anti-return hole 9. The anti-return rod 10 is made of threaded steel. Specifically, each of the left and right channel rails 4 has a coaxially arranged circular hole with a diameter of 42 mm, serving as the anti-return hole 9. A threaded steel bar with a diameter of 40 mm, serving as the anti-return rod 10, is inserted into both holes to achieve the desired anti-return effect.

[0025] Furthermore, a guardrail 5 - 1 with a height of 1.2 meters is installed on the side of the docking platform 5 to ensure the safety of operators walking at high altitude.

[0026] The following example illustrates how to use this embodiment.

[0027] Taking bucket 7 to Matoumen 3 well-drilling temporary facility work site needs two people at least, just can complete the docking of bucket 7 and Matoumen 3, passage work.

[0028] Step 1: After the bucket 7 reaches the horse head gate 3 and stops steadily, the operator on the bucket 7 first uses a hook to pull the wire rope 2 with a ring buckle at one end hanging on the horse head gate 3 to the side of the bucket 7. Remove the safety belt hook hanging on the bucket 7 and connect the safety belt hook to the wire rope 2 to ensure the inherent safety of the height operation personnel.

[0029] Step 2: After the safety belt is connected to the wire rope 2, use a hook to pull the four-meter-long docking platform 5 out of the track 4 installed on the bottom plate of the horse head door 3, so that the front edge of the docking platform 5 is above the wall of the bucket 7. Then, turn the folding plate 6 over and attach it to the upper side of the bucket 7 wall, so that the docking platform 5 firmly clamps the bucket 7 to prevent it from moving and ensure the safety of people walking.

[0030] Step 3: One person in the bucket 7 first passes through the docking platform 5 and enters the horse-head gate 3. They open the fence and lock the gate, inserting the check rod 10 to prevent the docking platform 5 from moving toward the horse-head gate 3. After all the relevant personnel, materials, and equipment have entered the horse-head gate 3, they flip the folding plate 6 back into place, withdraw the check rod 10, and finally retract the docking platform 5 into the horse-head gate 3. The bucket 7 can now move upward.
