Description

Technical Field

[0001] The utility model belongs to the field of prefabricated cabins, and in particular relates to a hanging shaft and a prefabricated cabin. Background Art

[0002] With the development of the economy, new demands have been made on the efficiency of power construction. Therefore, in order to further shorten the power construction cycle, the model of "factory processing and prefabricated construction" is gradually becoming a trend in power construction. The prefabricated cabin is the product of this model. The prefabricated cabin is a carrier of power equipment. Its size meets the requirements of road transportation and can accommodate multiple power equipment. The prefabricated cabin is prefabricated in the factory, and after the internal equipment is installed and wired, it is transported as a whole to the site of use.

[0003] In order to facilitate the movement of the prefabricated cabin, a suspension shaft is usually configured during the manufacture of the prefabricated cabin. For example, the application number is CN202311242501.6, and the name is: A prefabricated cabin base and a prefabricated cabin. It discloses that a suspension shaft is configured on the bottom of the prefabricated cabin, and the suspension shaft can help the prefabricated cabin move.

[0004] However, after the prefabricated cabin arrives at the installation location, it is usually not moved again, or the probability of moving it is small. Therefore, the conventional hanging shaft cannot be disassembled because it is fixed to the prefabricated cabin, which leads to a low utilization rate of the hanging shaft.

[0005] In summary, the hanging shaft in the prior art has the problem of low utilization rate. Utility Model Content

[0006] The utility model provides a suspension shaft and a prefabricated cabin, aiming to solve the problem of low utilization rate of the suspension shaft.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a hanging shaft, including a shaft body and a limiting part, wherein the limiting part is installed at the two end ends of the shaft body, and also includes a threaded connection structure, wherein the threaded connection structure is located at both ends of the shaft body, and the limiting parts at both ends are detachably connected to the shaft body through the threaded connection structure.

[0008] The suspension shaft in this solution is composed of a limiter and a shaft body, and the limiter and the shaft body can be separated. Therefore, when the suspension shaft needs to be used, the limiter can be installed on the shaft body; when the suspension shaft is not needed, the limiter and the shaft body are separated to disassemble the suspension shaft. Since the suspension shaft can be disassembled and installed as needed, the suspension shaft can be installed at different positions when it needs to be used, thereby achieving higher utilization.

[0009] Preferably, in order to realize the connection and separation of the limiting part and the shaft body in Scheme 1, the threaded connection structure includes a first threaded hole and a threaded component, the first threaded hole and the threaded component are respectively arranged on the shaft body and the limiting part, and the threaded component is connected to the first threaded hole, so that the limiting part and the shaft body can be detachably connected.

[0010] In the first solution, the threaded component and the first threaded hole can be connected and separated by threads. Therefore, when the limiter and the shaft body need to be connected, it is only necessary to connect the threaded component and the first threaded hole. This solution realizes the connection and separation of the limiter and the shaft body through a threaded connection structure. Compared with other connection methods, the threaded connection is more secure and has a simpler structure.

[0011] Preferably, in order to adapt to the first threaded hole, the threaded component may be a bolt;

[0012] Alternatively, in order to adapt the threaded component to the first threaded hole, the threaded component may be a screw.

[0013] Preferably, in order to prevent the bolt from loosening and solve the problem of the shaft body and the limiting part being separated due to the loosening of the bolt, the bolt is preferably provided with a spring washer.

[0014] In this solution, an elastic pad is arranged on the bolt, and the elastic pad realizes locking of the bolt, making the bolt more stable. The bolt in a stable state is less likely to loosen, thus solving the problem of the shaft body and the limit part being separated due to the loosening of the bolt.

[0015] In order to allow the bolt to pass through the limiting portion and be matched with the first threaded hole, the limiting portion is configured with a mounting hole for matching the bolt.

[0016] This solution provides a mounting hole for bolt installation, the bolt passes through the limiting part, and the bolt can be adapted to the first threaded hole. At the same time, when the bolt is adapted to the first threaded hole, the bolt constrains the limiting part, so that the limiting part is installed on the end of the shaft body.

[0017] Preferably, in order to realize the connection and separation between the limiting part and the shaft body in Scheme 2, the threaded connection structure includes a second threaded hole and an external thread, and the external thread and the second threaded hole are respectively arranged on the shaft body and the limiting part, and the external thread is connected to the second threaded hole to realize a detachable connection between the limiting part and the shaft body.

[0018] Solution 2 is a threaded connection between the external thread and the second threaded hole. Therefore, when the limiter and the shaft body need to be connected, it is only necessary to connect the external thread and the second threaded hole. This solution realizes the connection and separation of the limiter and the shaft body through a threaded connection structure. Compared with other connection methods, the threaded connection is more secure and has a simpler structure.

[0019] Preferably, the limiting portion is a limiting piece.

[0020] In order to improve the supporting force of the shaft body, the shaft body is a solid shaft. When the solid shaft is adapted with a sling or a steel rope, the solid shaft has a stronger supporting force and the solid shaft will not be deformed.

[0021] The second aspect of the utility model provides a prefabricated cabin, comprising a mounting component and the above-mentioned suspension shaft, wherein the mounting component is configured with a through hole, and the suspension shaft is installed in the through hole.

[0022] In this solution, the suspension shaft is installed in the through hole, and the suspension shaft is adapted to the through hole. Therefore, when the suspension shaft is adapted to the sling or the steel rope, the suspension shaft can drive the prefabricated cabin to move.

[0023] Preferably, in order to solve the problem of interference caused by the hanging shaft protruding for a long time, the hanging shaft described in this solution can be telescopically installed in the through hole.

[0024] The suspension shaft of this solution can be installed telescopically. When the suspension shaft is extended, the suspension shaft cooperates with the sling and the steel rope. When the suspension shaft is not needed, the suspension shaft retracts to solve the problem of interference caused by the protrusion of the suspension shaft. At the same time, when the suspension shaft retracts, the retracted suspension shaft blocks the through hole, solving the problem of external impurities entering the through hole.

[0025] Preferably, in order to form the through hole, the mounting component is a channel steel, an H-shaped steel or a rectangular tube.

[0026] Preferably, in order to increase the supporting force of the suspension shaft, the suspension shaft described in this solution is provided with a supporting component.

[0027] In this solution, a supporting component is arranged on the hanging shaft, and the supporting component supports the hanging shaft. When the hanging shaft is adapted to the sling or the steel rope, the load-bearing capacity of the hanging shaft is stronger.

[0028] The beneficial effect of the utility model is that the suspension shaft in the present solution is composed of a limiting part and a shaft body, and the limiting part and the shaft body can be separated. Therefore, when the suspension shaft needs to be used, the limiting part can be installed on the shaft body; when the suspension shaft is not needed, the limiting part is separated from the shaft body to realize the disassembly of the suspension shaft. Since the suspension shaft can be disassembled and installed as needed, the suspension shaft can be installed at different positions when it needs to be used, thereby achieving higher utilization rate.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0040] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0041] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0042] Example 1

[0043] Basically as attached Figure 1 To Attachment Figure 2 As shown, a suspension shaft 1 is used to cooperate with a suspension belt or a steel rope.

[0044] The suspension shaft 1 in the embodiment includes a shaft body 11 and a stopper 12. The shaft body 11 is in an elongated shape, specifically a cylindrical, rectangular or polygonal column shape, etc. At the same time, since the shaft body 11 needs to be subjected to force, the shaft body 11 is preferably a solid body, thereby ensuring that the strength of the entire shaft body 11 is higher.

[0045] In the embodiment of the present disclosure, the limiting part 12 is specifically a limiting piece, which can be in the shape of a circular piece or a rectangular piece. Of course, in some other embodiments, the limiting part 12 can also be a limiting block, etc. The limiting part 12 is mainly used to limit the sliding of the sling or steel rope when it cooperates with the sling or steel rope, to prevent the suspension shaft 1 from separating from the sling or steel rope, and to ensure stable lifting.

[0046] like Figure 2 As shown, in the embodiment of the present disclosure, the limiting portion 12 is preferably installed at the end of the shaft body 11 through a threaded connection structure 13. Figure 3 As shown, the threaded connection structure 13 in the embodiment of the present disclosure includes a first threaded hole 131 and a threaded component, and more preferably the threaded component is a bolt 132. In implementation, the first threaded hole 131 is constructed at the end of the shaft body 11, and a mounting hole 132b is provided on the limiting plate, and the mounting hole 132b penetrates the limiting plate. When the bolt 132 passes through the mounting hole 132b and is threadedly connected to the first threaded hole 131, the limiting plate is installed to the end of the shaft body 11, as shown in FIG. Figure 3 When the bolt 132 is separated from the first threaded hole 131, the stopper can be separated from the shaft body 11. Figure 4 shown.

[0047] Take an application scenario as an example: since the shaft body 11 and the limiting part 12 of the suspension shaft 1 can be separated, when the suspension shaft 1 needs to be installed, it is only necessary to separate the shaft body 11 and the limiting part 12, and then after the shaft body 11 is installed, install the limiting part 12 on the shaft body 11, and the limiting part 12 and the shaft body 11 are combined to form the suspension shaft 1. When the suspension shaft 1 is used, separate the shaft body 11 and the limiting part 12, and then remove the shaft body 11. Through the above process, the suspension shaft 1 can be installed when it is needed and disassembled when it is not needed, which is convenient for use. At the same time, it is also possible to install the suspension shaft 1 in different prefabricated cabins, and the utilization rate of the suspension shaft 1 is higher.

[0048] In order to ensure that the bolt 132 will not loosen due to force after being connected to the first threaded hole 131, and solve the problem of separation of the sling or steel rope from the suspension shaft 1, a spring washer is arranged on the bolt 132 in the embodiment of the disclosure. The spring washer improves the tightness of the bolt 132 and prevents the bolt 132 from loosening. Figure 4 shown.

[0049] The following is a further detailed description through a specific embodiment: when the suspension shaft 1 needs to be disassembled, the limiter 12 can be separated from the shaft body 11 by rotating the bolt 132. When the suspension shaft 1 needs to be used for hoisting, the limiter 12 is connected to the shaft body 11 through the bolt 132.

[0050] Example 2

[0051] The main difference between the embodiment of the present disclosure and embodiment 1 is that Figure 5 As shown, in the embodiment of the present disclosure, the first threaded hole 131 is arranged in the middle of the limiting portion 12, and the threaded component is arranged at the end of the connecting shaft. The threaded component is preferably a screw rod 133. During implementation, the screw rod 133 is installed by welding.

[0052] In the embodiment of the present disclosure, the first threaded hole 131 is threadedly connected to the screw rod 133 , thereby realizing that the limiting portion 12 can be detachably mounted on the end of the shaft body 11 .

[0053] Example 3

[0054] The main difference between the embodiment of the present disclosure and the embodiment 1 and the embodiment 2 is that the threaded connection structure 13 is different. Figure 6 As shown, the threaded connection structure 13 in the embodiment of the present disclosure includes a second threaded hole 134 and an external thread, the external thread is provided on the outer surface of the suspension shaft 1, and the second threaded hole 134 is provided on the limiting portion 12. When the suspension shaft 1 is embedded in the second threaded hole 134, the limiting portion 12 is installed on the suspension shaft 1.

[0055] Example 4

[0056] The embodiments of the present disclosure provide a prefabricated cabin, which includes a mounting component 2 and a suspension shaft 1 of Embodiment 1, Embodiment 2 or Embodiment 3.

[0057] In the embodiment of the present disclosure, the installation component 2 can be a side wall of a prefabricated cabin, or the installation component 2 can be a installation component 2, such as a channel steel, an H-shaped steel or a rectangular tube. The installation component 2 is then fixedly installed on the prefabricated cabin, and can be installed by welding.

[0058] The mounting component 2 of the embodiment of the present disclosure is provided with a through hole 21, which penetrates the mounting component 2. The interior of the through hole 21 is used for mounting the suspension shaft 1, and the shape of the through hole 21 is adapted to the shape of the shaft body 11. For example, when the shaft body 11 is cylindrical, the through hole 21 is a circular hole; when the shaft body 11 is a triangular prism, the through hole 21 is a triangular hole, and so on.

[0059] In the disclosed embodiment, the length of the through hole 21 is less than the length of the shaft body 11, and the diameter of the through hole 21 is slightly larger than the diameter of the shaft body 11. The suspension shaft 1 is telescopically mounted in the through hole 21. Since the suspension shaft 1 is telescopically mounted, when the suspension shaft 1 is needed, the suspension shaft 1 can be pulled out so that the shaft body 11 is exposed, and the shaft body 11 of the suspension shaft 1 can cooperate with the sling or steel rope. When the suspension shaft 1 is not needed, the suspension shaft 1 can be retracted, thereby solving the problem that the suspension shaft 1 is extended and hinders the use.

[0060] In order to solve the problem of external liquid entering the prefabricated cabin from the through hole 21, the size of the limiter 12 in the embodiment of the present disclosure is larger than the size of the through hole 21, and the limiter 12 can completely cover the through hole 21. Therefore, when the suspension shaft 1 is in the retracted state, the limiter 12 closes the end of the through hole 21, thereby solving the problem of external liquid entering the interior of the prefabricated cabin. In addition, in order to achieve a better waterproof effect, the embodiment of the present disclosure can be provided with a waterproof layer on the inner side of the limiter 12, and the through hole 21 is further closed by the waterproof layer, thereby preventing liquid from entering the interior of the through hole 21.

[0061] It should be noted that: Figure 7 As shown, when the mounting component 2 is a rectangular tube, since the interior of the rectangular tube is hollow, the bearing capacity of the suspension shaft 1 will obviously be affected. At this time, in order to improve the bearing capacity of the suspension shaft 1, a support component 3 can be provided inside the rectangular tube in the embodiment of the present disclosure, and the bearing capacity of the suspension shaft 1 is increased by the support component 3. The support component 3 during the implementation of the present disclosure can be a support tube. The support tube is fixedly connected to the inner wall of the rectangular tube, and the rectangular tube remains stable. The shaft body 11 of the suspension shaft 1 is accommodated inside the support tube. Therefore, when the suspension shaft 1 is matched with a sling or a steel rope, the support tube contacts the suspension shaft 1, thereby improving the bearing capacity of the suspension shaft 1.

[0062] It should be noted that: Figure 8 As shown, when the mounting component 2 is an H-shaped steel, support plates are welded and installed on the left and right sides of the H-shaped steel. The through hole 21 runs through the support plates and the H-shaped steel on both sides, and the suspension shaft 1 is accommodated in the through hole 21. Since the support plates are welded and installed on the left and right sides of the H-shaped steel, the left and right sides of the H-shaped steel are hollow. Therefore, in order to improve the bearing capacity of the suspension shaft 1, a support component 3 can be arranged in the through hole 21 in the embodiment of the present disclosure, and the bearing capacity of the suspension shaft 1 is increased by the support component 3. The support component 3 during the implementation of the present disclosure is a support tube. The support tube is installed inside the through hole 21 by welding. The inside of the support tube is used to accommodate the shaft body 11 of the suspension shaft 1. Therefore, when the suspension shaft 1 is matched with a sling or a steel rope, the support tube contacts the suspension shaft 1, thereby improving the bearing capacity of the suspension shaft 1.

[0063] It should be noted that: Fig. 9As shown, when the mounting component 2 is a channel steel, a support plate is provided on one side of the channel steel. A through hole 21 is provided through the support plate and the channel steel, and the suspension shaft 1 is accommodated in the through hole 21. When the support plate is provided on one side of the channel steel, the side surface of the channel steel is hollow. Therefore, in order to improve the carrying capacity of the suspension shaft 1, a support component 3 can be arranged in the through hole 21 in the embodiment of the present disclosure, and the carrying capacity of the suspension shaft 1 is increased by the support component 3. The support component 3 during the implementation of the present disclosure is a support tube. The support tube is installed inside the through hole 21 by welding. The interior of the support tube is used to accommodate the shaft body 11 of the suspension shaft 1. Therefore, when the suspension shaft 1 is matched with a sling or a steel rope, the support tube contacts the suspension shaft 1, thereby improving the carrying capacity of the suspension shaft 1.

[0064] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
