Description

Technical Field

[0001] This utility model relates to the field of vertical shaft excavation construction technology, specifically to an automatic unloading device for excavated slag in vertical shaft excavation. Background Technology

[0002] Shaft construction refers to the general term for the excavation, construction, and equipment installation of vertical wells during the extraction of underground sediments. Based on the geological and hydrogeological differences of the wellbore passing through rock strata, shaft structures are divided into two types: ordinary methods for surface soil layers and bedrock sections, and special methods. During shaft excavation, the excavated material needs to be transported from the bottom of the shaft to the surface in a timely manner to ensure effective downward excavation and prevent the excavated material from accumulating and clogging the shaft. Existing mechanisms for lifting excavated material store it in hoppers and then raise the hoppers to the surface via steel cables. However, due to the large amount of material in the hoppers, operators at the shaft opening need to discharge the material from the hoppers. Currently, unloading shaft materials mainly involves manually emptying the hoppers to remove the excavated material. This method is inefficient and needs improvement. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides an automatic unloading device for excavated slag in vertical shaft excavation. This device can unload slag without the need for manual dumping of the hopper, reducing the workload of workers and improving construction efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic unloading device for excavated slag in vertical shafts, comprising an unloading box with openings at both the top and bottom, an opening and closing plate disposed at the lower opening of the unloading box, and a locking mechanism for locking the opening and closing plate, wherein one side of the opening and closing plate is rotatably connected to the lower end of the unloading box.

[0005] With the above structural design, the excavated material in the vertical shaft can be directly unloaded from the bottom of the unloading box, eliminating the need for manual dumping of the material from the hopper, reducing the workload of workers and improving construction efficiency.

[0006] Preferably, the locking mechanism includes a locking hook for locking the opening and closing plate, a driven gear fixedly connected to the upper end of the locking hook, a gear meshing with the driven gear, an electric push rod fixedly connected to the gear rod, and a battery electrically connected to the electric push rod. The locking hook is rotatably connected to the lower end of the unloading box, the gear rod is slidably connected to the box wall of the unloading box, and the electric push rod and the battery are both fixedly connected to the outer side wall of the unloading box.

[0007] With the above structural design, when lifting the unloading box, the locking hook engages with the opening and closing plate, which seals the lower end of the unloading box to transport the excavated slag from the shaft. When the lifting device raises the unloading box above the slag dumping site, the electric push rod is activated, the locking hook rotates 90 degrees, and the locking hook no longer engages with the opening and closing plate. The opening and closing plate then opens, and the excavated slag from the shaft falls from inside the unloading box to the slag dumping site. The opening and closing of the plate is indirectly achieved by rotating the locking hook. The operation is simple, and there is no need for manual opening of the opening and closing plate, which reduces the workload of workers and improves construction efficiency.

[0008] Preferably, multiple sets of locking hooks are provided, and the locking hooks are evenly spaced on the side opposite to the rotating side of the opening and closing plate.

[0009] By adopting the above structural design and setting multiple locking hooks, the ability of this device to lock the opening and closing plate is improved.

[0010] Preferably, the locking hook includes a rotating rod and a locking rod fixedly connected to the lower end of the rotating rod. The middle part of the rotating rod is fixedly connected to a bearing seat, the bearing seat is fixedly connected to the unloading box, and the driven gear is fixedly connected to the upper end of the rotating rod.

[0011] The above structural design prevents the locking hook from falling off the unloading box.

[0012] Preferably, multiple pads are fixedly connected to the back of the opening and closing plate.

[0013] With the above structural design, when the unloading box is placed on the ground, the pad can create a height difference between the bottom surface of the opening and closing plate and the ground to accommodate the locking hook, preventing the locking hook from being pressed on the ground and unable to rotate. Moreover, the pad can enhance the strength of the opening and closing plate and prevent it from deforming under stress.

[0014] Preferably, a micro switch is fixedly connected to the lower end of the unloading box, and the micro switch is electrically connected to the electric push rod.

[0015] With the above structural design, when the opening and closing plate is closed, the opening and closing plate touches the micro switch, which activates the electric push rod, and the locking hook can automatically rotate to lock the opening and closing plate.

[0016] Preferably, the upper end of the pull rope is fixedly connected to the unloading box, and the lower end of the pull rope is fixedly connected to the opening and closing plate. When the pull rope is tensioned, the angle between the opening and closing plate and the unloading box is an acute angle.

[0017] The above structural design avoids excessive rotation of the opening and closing plate, and the pull rope can limit the rotation angle of the opening and closing plate, making it easier to close the opening and closing plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This device eliminates the need for manual opening or closing of the opening and closing plates, and eliminates the need for manual emptying of the unloading box, thus reducing the workload of workers and improving construction efficiency. Attached Figure Description

[0023] Figure 4 This utility model Figure 2 Enlarged structural diagram at point A; Detailed Implementation

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 This utility model provides a technical solution: an automatic unloading device for slag material excavation in vertical shafts, including an unloading box 1 with openings at both the top and bottom, an opening and closing plate 2 set at the lower opening of the unloading box 1, and a locking mechanism for locking the opening and closing plate 2. One side of the opening and closing plate 2 is rotatably connected to the lower end of the unloading box 1, and another side of the opening and closing plate 2 is connected to one side of the lower end of the unloading box 1 through a door hinge support. An ear plate 11 is fixedly connected to each of the four corners of the upper end of the unloading box 1. The ear plate 11 is fixedly connected to the lower end of the lifting rope 12, and the upper end of the lifting rope 12 is fixedly connected to the lifting ring 13.

[0025] The locking mechanism includes a hook 3 for locking the opening and closing plate 2, a driven gear 41 fixedly connected to the upper end of the hook 3, a gear 42 meshing with the driven gear 41, an electric push rod 43 fixedly connected to the gear 42, and a battery 44 electrically connected to the electric push rod 43. The hook 3 is L-shaped and rotatably connected to the lower end of the unloading box 1. The gear 42 is slidably connected to the wall of the unloading box 1. The electric push rod 43 and the battery 44 are both fixedly connected to the outer wall of the unloading box 1. A groove matching the back of the gear 42 is provided on the outer wall of the lower end of the unloading box 1. The electric push rod 43 is equipped with a remote control 9, which allows the operator to control the electric push rod 43 to extend or retract.

[0026] Multiple sets of locking hooks 3 are provided, and the locking hooks 3 are equally spaced on the side opposite to the rotating side of the opening and closing plate 2.

[0027] Please see Figure 1 and Figure 2The locking hook 3 includes a rotating rod 31 and a locking rod 32 fixedly connected to the lower end of the rotating rod 31. The middle part of the rotating rod 31 is fixedly connected to a bearing 45, which is fixedly connected to the unloading box 1. The driven gear 41 is fixedly connected to the upper end of the rotating rod 31. The number of driven gears 41 is the same as the number of locking hooks 3. One driven gear 41 is fixedly connected to the upper end of each locking hook 3. All driven gears 41 mesh with the rack 42. When the electric push rod 43 pushes the rack 42 to slide, the rack 42 drives all the driven gears 41 to rotate.

[0028] To prevent the locking hook 3 from being pressed against the ground by the unloading box 1 and thus unable to rotate, multiple pads 6 are fixedly connected to the back of the opening and closing plate 2. The pads 6 are arranged at equal intervals on the back of the opening and closing plate 2, with the spacing between the pads 6 being greater than the length of the locking rod 32, and the height of the pads 6 being greater than the height of the locking rod 32. Moreover, the pads 6 can enhance the strength of the opening and closing plate and prevent it from deforming under stress.

[0029] In order to enable the locking hook 3 to automatically lock the opening and closing plate 2 after it is closed, a micro switch 7 is fixedly connected to the lower end of the unloading box 1. The micro switch 7 is electrically connected to the electric push rod 43. A trigger plate 71 is fixedly connected to the edge of the opening and closing plate 2. When the opening and closing plate 2 is closed, the trigger plate 71 just touches the micro switch 7. The micro switch 7 transmits an electrical signal to the electric push rod 43. The electric push rod 43 moves and drives the rack 42 to move. The driven gear 41 that meshes with the rack 42 rotates 90 degrees. After the locking hook 3 rotates, it hooks the opening and closing plate 2.

[0030] The upper end of the pull rope 8 is fixedly connected to the unloading box 1, and the lower end of the pull rope 8 is fixedly connected to the opening and closing plate 2. When the pull rope 8 is taut, the angle between the opening and closing plate 2 and the unloading box 1 is an acute angle, which is between 80 and 85 degrees. This prevents the opening and closing plate 2 from overturning due to the impact of the slag during unloading. When the lifting device lifts the unloading box 1 above the slag storage site, and the opening and closing plate 2 opens to unload the slag, the operator manipulates the lifting device to place the unloading box 1 on the ground. The lower end of the opening and closing plate 2 touches the ground first. Since the angle between the opening and closing plate 2 and the unloading box 1 is acute at this time, the opening and closing plate 2 will gradually close. When the unloading box 1 is completely on the ground, the opening and closing plate 2 will automatically close.

[0031] Working principle: When lifting the unloading box 1, the locking hook 3 engages with the opening and closing plate 2, which seals the lower end of the unloading box 1, allowing the excavated slag from the shaft to be transported out. When the lifting device raises the unloading box 1 above the slag dumping site, the operator presses the button on the remote control 9 to activate the electric push rod 43. The electric push rod 43 retracts the gear 42, and the driven gear 41 rotates the locking hook 3 90 degrees. The locking hook 3 no longer engages with the opening and closing plate 2, and the opening and closing plate 2 opens, allowing the excavated slag from the shaft to fall from the unloading box 1 to the slag dumping site. At this time, the operator... The lifting device is used to place the unloading box 1 on the ground. The lower end of the opening and closing plate 2 touches the ground first. Since the angle between the opening and closing plate 2 and the unloading box 1 is acute at this time, the opening and closing plate 2 will not rotate in the opposite direction and will gradually close. When the unloading box 1 is completely on the ground, the trigger plate 71 on the opening and closing plate 2 just touches the micro switch 7. The micro switch 7 transmits an electrical signal to the electric push rod 43. The electric push rod 43 moves and drives the rack 42 to move. The driven gear 41 that meshes with the rack 42 rotates 90 degrees in the opposite direction. After the locking hook 3 rotates, it hooks the opening and closing plate 2 and the next material transportation is carried out.
