Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figure 1-2 , a novel fixture for hoisting calcium carbide pots in this embodiment is used for hoisting calcium carbide pots, and the hoisting and unloading of calcium carbide pots can be realized with the participation of personnel.

[0029] Specifically, it includes a rectangular frame 1 and two side plates 2. Both side plates 2 are vertically installed inside the rectangular frame 1; inside both side plates 2, a connecting plate 3 is slidably connected. Corresponding to the two connecting plates 3, a chute 4 is opened from bottom to top inside the side plate 2 so that the connecting plate 3 can move up and down inside the chute 4; a hanging bracket 5 is assembled between the opposite sides of the two connecting plates 3, and a connecting hole is opened inside the hanging bracket 5 and near its upper end surface.

[0030] During the actual use process, the connecting hole inside the hanging bracket 5 is connected to the hook on the gantry crane to hoist the calcium carbide pot.

[0031] One end of each of the two connecting plates 3 facing away from each other is hinged with two first clamping arms 6 through a hinge seat. One end of each of the two first clamping arms 6 away from the hinge seat is hinged with a second clamping arm 7 through a hinge shaft, and the middle parts of the two second clamping arms 7 are rotatably connected. A locking component 8 is arranged inside the lifting frame 5. Corresponding to the locking component 8, a connecting piece 9 is arranged inside the rectangular frame 1 for locking the distance between the lifting frame 5 and the rectangular frame 1.

[0032] During actual setting, clamping plates 10 are installed at the bottoms of the second clamping arms 7 on the left and right sides, and cross plates are installed on the upper surfaces of the second clamping arms 7 on the left and right sides.

[0033] During actual use, when it is necessary to lift the calcium carbide pot, first move the hoisting device to the position where the calcium carbide pot is placed by the gantry, and at the same time make the two clamping plates 10 located on the left and right sides of the calcium carbide pot respectively. At this time, lift the lifting frame 5, thereby driving the connecting plates 3 on both sides to move upward, increasing the distance between the hinge seat and the rotating shaft. At the same time, the ends of the two first clamping arms 6 away from the hinge seat move towards each other during the rising process, so that the clamping plates 10 on the bottoms of the two second clamping arms 7 move towards each other and fit against the outer surface of the calcium carbide pot, thereby lifting the calcium carbide pot.

[0034] Please refer to Figure 3-4 , in order to enable the entire hoisting device to automatically open when unloading the calcium carbide pot, the locking component 8 in this embodiment includes a sleeve 801 and a connecting bolt 802. The sleeve 801 is assembled inside the lifting frame 5, and the connecting bolt 802 is slidably connected inside the sleeve 801. An annular groove is formed on the outer surface of the connecting bolt 802, and four arc-shaped blocks 804 are integrally formed on the upper and lower sides of the inner wall of the annular groove. There is a certain gap between the upper and lower arc-shaped blocks 804, and the gap between the two forms an S-shaped groove 803. Corresponding to the S-shaped groove 803, two guide rods 805 are installed on the outer surface of the sleeve 801 on the opposite sides through bolts, and a limiting block 806 is arranged at the bottom of the connecting bolt 802.

[0035] Specifically, the connecting piece 9 includes a locking plate 901. The locking plate 901 is assembled between the left and right sides of the inner wall of the rectangular frame 1, and a rectangular connecting port is vertically formed inside the locking plate 901.

[0036] A housing 902 communicating with the connecting port is assembled on the lower surface of the locking plate 901, so that the limiting block 806 at the bottom of the connecting bolt 802 can extend into the interior of the housing 902 through the connecting port.

[0037] It should be noted that when the limiting block 806 is not under force, at this time the guide rod 805 is located between the two adjacent upper arc-shaped blocks 804, and the front shape projection of the arc-shaped block 804 is triangular, and the included angle between two adjacent arc-shaped blocks 804 is ninety degrees.

[0038] During actual use, when the calcium carbide pot is placed in the placement area, the hook on the gantry continues to move downward. At this time, the lifting frame 5 continues to move downward due to its weight. When the limit block 806 at the bottom of the connecting bolt 802 extends into the inside of the locking plate 901 and the housing 902 and contacts the inner bottom wall of the housing 902, the connecting bolt 802 can be pushed upward accordingly, causing the two guide rods 805 to fall between the two lower arc-shaped blocks 804. At this time, the lifting frame 5 can be lifted again. Then, the guide rods 805 will fall into the space between the adjacent two arc-shaped blocks 804 along the inclined channels between the two arc-shaped blocks 804 on both sides. At this time, both the limit block 806 and the connecting bolt 802 rotate by ninety degrees.

[0039] Furthermore, when the limit block 806 rotates by ninety degrees, the limit block 806 and the locking plate 901 are in a cross-shaped state, and at the same time, the two clamping plates 10 are at the maximum opening angle, so that the calcium carbide pot can be unloaded from the inside of the lifting device.

[0040] Even further, to ensure the stability of the lifting frame 5, in this embodiment, the top view projection shape of the connecting plate 3 is T-shaped, and the width of the side connected to the lifting frame 5 in the Y-axis direction is greater than the width of the chute in the Y-axis direction, thereby enhancing the stability of the lifting frame 5 during the lifting process.

[0041] It should be noted that to ensure that the distance between the two clamping plates 10 can be effectively fixed after the limit block 806 fits against the lower surface of the locking plate 901, in this embodiment, the length of the connection port in the X-axis direction is less than the length of the limit block 806 in the Y-axis direction. That is, when the limit block 806 fits against the lower surface of the locking plate 901, the lifting frame 5 can no longer move up and down.

[0042] In addition, to ensure the up and down movement of the connecting bolt 802 inside the sleeve 801, a certain gap is reserved between the top of the connecting bolt 802 and the inner top wall of the sleeve 801.

[0043] In actual setting, by reserving a certain gap between the connecting bolt 802 and the sleeve 801, it is ensured that when the lifting frame 5 moves up and down, the connecting bolt 802 can move up and down inside the sleeve 801.

[0044] The working principle of the above embodiment is as follows:

[0045] (1) After the calcium carbide pot is placed in the placement area, the hook on the gantry is continuously moved downward. When the two clamping plates 10 contact the ground, at this time, the lifting frame 5 continues to move downward due to its weight, so that the limit block 806 at the bottom of the connecting bolt 802 extends into the inside of the locking plate 901 and the housing 902 and contacts the inner bottom wall of the housing 902. At this time, the connecting bolt 802 can be pushed upward accordingly, so that the two guide rods 805 fall between the two lower arc-shaped blocks 804. Then the lifting frame 5 is lifted again. At this time, the guide rods 805 will fall into the adjacent two arc-shaped blocks 804 along the inclined channels between the two arc-shaped blocks 804 on both sides, and the limit block 806 and the connecting bolt 802 both rotate by ninety degrees. When the limit block 806 rotates by ninety degrees, the limit block 806 and the locking plate 901 are in a cross state, and at the same time, the two clamping plates 10 are at the maximum opening angle, and the calcium carbide pot can be unloaded from the inside of the lifting device.

[0046] (2) Conversely, when it is necessary to clamp the calcium carbide pot, first lower the lifting frame 5 so that the limit block 806 rotates by ninety degrees again after contacting the bottom of the housing 902, so that the limit block 806 can be removed from the inside of the locking plate 901, so that the lifting frame 5 can continue to move up and down.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
