[0032] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0033] In the present disclosure, the orientation words such as "upper" and "lower" are defined with respect to the arrangement direction of the hoist when actually used, and the orientation words such as "inner" and "outer" are defined with respect to the outline of the corresponding components. The use of the terms "first", "second", and the like is intended to distinguish different components, and does not have sequential and important meanings. In addition, in the following description, the same reference numerals in different drawings represent the same or similar elements unless otherwise explained.

[0034] According to an embodiment of the present disclosure, as shown in Figures 1 to 6 a hoist is provided, which includes a drum 1, a clutch 2, and a first support 3. The drum 1 has a groove 11 formed in one end thereof in a first direction. The clutch 2 can be arranged in the groove 11, and the first support 3 has one end fixed to the ground 6 and the other end arranged opposite to the opening of the drum 1 in the first direction, so as to limit the clutch 2 in the groove 11.

[0035] By the technical scheme, the elevator comprises the first support 3 arranged in front of the opening of the drum 1 to limit the clutch 2, so as to prevent the clutch 2 from completely coming out of the groove 11, thereby preventing personnel casualties and material losses caused by the falling of the lifting container, reducing the probability of deformation of other components of the elevator due to impact, improving the safety of mining production, reducing the difficulty of subsequent resetting and repairing of the elevator, and thereby reducing the repair cost of the elevator.

[0036] It should be noted that, as shown in Figure 6 , the groove 11 accommodating the clutch 2 is located at one end of the drum 1, and the groove bottom of the groove 11 is a partition plate 111 separated from the inside of the drum 1, and the partition plate 111 is provided with a through hole to connect the components inside the drum 1 with the clutch 2 through the through hole. In addition, the relative arrangement mentioned above can be that the first support 3 directly contacts the drum 1, or the first support 3 has a certain interval with the drum 1. Since the slight coming-out of the clutch 2 from the groove 11 has little effect on the normal work of the elevator, when the first support 3 and the drum 1 are installed, a certain distance can be provided therebetween to improve the fault tolerance rate of installation. A safe distance of coming-out of the clutch 2 can be set according to the actual use of the elevator, and before the clutch 2 comes out of the safe distance, the elevator can work normally. However, after the clutch 2 comes out of the safe distance, if it continues to come out, there is a risk of falling of the lifting container and deformation of other components of the elevator due to impact, so when installing, the interval between the first support 3 and the drum 1 is not greater than the safe distance, which ensures the limiting effect of the first support 3 while taking into account the fault tolerance rate of installation, thereby improving the safety of the elevator operation. The value of the safe distance can be set according to actual needs, and the present disclosure does not limit it.

[0037] Further, as shown in Figures 1 to 3 , the first support 3 can include a fixing member 31 and a limiting rod 32. The fixing member 31 can be arranged at an interval with the drum 1 in the second direction, one end of the fixing member 31 is used to be fixed to the ground 6, and the other end extends away from the ground 6. One end of the limiting rod 32 can be connected with the fixing member 31, and the other end extends to the outside of the opening of the groove 11 along the second direction towards the drum 1 to be opposite to the clutch 2. When the elevator works normally, as shown in Figure 4 , the clutch 2 is completely located in the groove 11, and since the limiting rod 32 is spaced apart from the drum 1, the limiting rod 32 is also spaced apart from the clutch 2 at this time. When the clutch 2 comes out of the groove 11, as shown in Figure 5As shown, the limiting rod 32 can timely block the clutch 2 to prevent the clutch 2 from falling out of the groove 11 and being damaged. The fixing member 31 can be plug-removably arranged on the ground 6, and the fixing member 31 can include a bolt 311 and two nuts 312. The head of the bolt 311 can be used to be buried under the ground 6, and the rod of the bolt 311 is used to pass out the ground 6 and the limiting rod 32 in turn. The two nuts 312 can be matched with the bolt 311 respectively, and the limiting rod 32 is located between the two nuts 312.

[0038] In the installation process of the elevator, the drum 1 and the clutch 2 can be assembled first, and then the drum 1 is fixedly arranged on the ground 6. According to the arrangement position of the drum 1 and the clutch 2, the bolt 311 can be buried after the hole is punched in the corresponding position of the ground 6, and then the hole is fixed by using cement, so that the head of the bolt 311 is fixed in the ground 6, and the rod passes out of the ground 6. At this time, one nut 312 can be screwed into the bolt 311, and then the limiting rod 32 is arranged on the bolt 311, and finally the other nut 312 is screwed in. Since the limiting rod 32 can rotate when it is arranged on the bolt 311, the limiting rod 32 can be rotated at this time to adjust the distance between the other end of the limiting rod 32 and the clutch 2. After the position of the limiting rod 32 is adjusted, the two nuts 312 are tightened to clamp the limiting rod 32, so that the limiting rod 32 is limited and fixed on the bolt 311. When the clutch 2 needs to be adjusted, only one of the nuts 312 needs to be loosened, and the limiting rod 32 can rotate around the bolt 311. At this time, the limiting rod 32 can be adjusted so that it cannot block the clutch 2, and the position of the clutch 2 can be adjusted to reset the elevator. After the elevator is reset, the two nuts 312 are tightened again after the limiting rod 32 is rotated to the original position. In addition, when the limiting rod 32 needs to be replaced, only one nut 312 needs to be removed, and the limiting rod 32 can be removed from the bolt 311 for replacement. After the new limiting rod 32 is arranged on the bolt 311, the removed nut 312 can be screwed in.

[0039] According to an embodiment of the present disclosure, as shown in Figures 1 to 5 As shown, one end of the limiting rod 32 close to the clutch 2 can be sleeved with a buffer sleeve 321, so as to avoid the hard contact between the first support 3 and the clutch 2 when the clutch 2 is separated from the groove 11, thereby protecting the clutch 2 from being scratched. Here, the buffer sleeve 321 can be made of foam material or rubber material, and the present disclosure does not limit this.

[0040] According to an embodiment of the present disclosure, as shown in Figures 1 to 3As shown, the hoist further comprises a second support 4, one end of the second support 4 is used for fixing to the ground 6, and the other end is arranged opposite to the clutch 2 in the first direction, wherein the distance between the second support 4 and the drum 1 in the first direction is equal to the distance between the first support 3 and the drum 1 in the first direction. The first support 3 and the second support 4 can jointly limit the disengaged clutch 2 in the first direction. Here, the second support 4 can be arranged in a spaced manner with the first support 3, and can limit different positions of the clutch 2, which not only improves the limiting effect of the clutch 2, but also reduces the risk of fracture of the first support 3 due to excessive weight of the clutch 2. Here, the end of the second support 4 close to the clutch 2 can also be sleeved with a buffer sleeve, which is not limited in the present disclosure. Here, the second support 4 can be an L-shaped support, wherein the horizontal section of the L-shaped support is located above the first support 3, the vertical section of the second support 4 is located on the side of the first support 3 away from the drum 1 in the second direction, and the vertical section of the second support 4 is used for being pluggably arranged in the ground 6. The second support 4 and the first support 3 are installed on the same side, which can not only reduce the occupation of the factory space, but also can limit different positions of the clutch 2 in the height direction by locating the horizontal section of the second support above the first support 3, thereby improving the limiting effect.

[0041] Further, as shown in the drawings, Figures 1 to 3 Figures 1 to 3 The hoist can further comprise a distance sensor 5 arranged opposite to the clutch 2 in the first direction, the distance sensor 5 is used for acquiring the distance value between the clutch 2 and the distance sensor 5, and the distance sensor 5 is connected with an alarm device, the alarm device is used for starting when the acquired distance value is less than a preset distance, so as to alarm after the clutch 2 is disengaged from the drum 1 by a certain distance, thereby reminding the operator to come over for maintenance as soon as possible and resetting the hoist, thereby reducing the risk of accidents. Here, the distance sensor 5 can be arranged on the second support 4 or the first support 3, which is not limited in the present disclosure. The preset distance can be 0, or can be set to a value less than the distance between the first support 3 and the drum 1 according to requirements, which is not limited in the present disclosure.

[0042] In addition, in order to prevent the hoist from being further damaged after the clutch 2 is disengaged from the drum 1, the hoist can further comprise an emergency stop switch, which can be connected in series with the alarm device. When the alarm is triggered, the emergency stop switch is started at the same time, so that the hoist can be stopped working synchronously, thereby reducing the security risk and the probability of accidents.

[0043] The preferred embodiments of the present disclosure are described in detail in combination with the drawings, but the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept range of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection range of the present disclosure.

[0044] It should be further noted that various specific technical features described in the above specific embodiments can be combined in any suitable manner, and the disclosure will not be repeated here for various possible combinations.

[0045] In addition, various different embodiments of the disclosure can also be combined with each other as long as they do not contradict the idea of the disclosure, and they should also be considered as disclosed by the disclosure.
