Abstract
Description
Technical Field
[0001] The utility model relates to a prefabricated cabin, in particular to a prefabricated cabin with a ladder with a handle structure. Background Art
[0002] At present, in the existing prefabricated cabin, in order to facilitate the later maintenance and repair work, a ladder is provided on the outside of the cabin. Since the space problem of the prefabricated cabin during transportation needs to be considered, the existing ladder has the following defects in structural design:
[0003] 1. There are many welding points between the ladder and the cabin, and the back of the welding points is difficult to paint. As a result, when painting later, many welding points cannot be painted on the back. These unpainted areas will corrode over time, which can easily cause danger to local climbing.
[0004] 2. Due to the limitations of prefabricated cabin transportation, the distance between the ladder and the cabin cannot be greater than the width of the top edge of the cabin, and no auxiliary handrails can be set on the top of the cabin. This makes it difficult for workers to climb up and down the top of the cabin, especially when coming down. Due to limited vision, it is difficult to find the foothold of the ladder, so maintenance personnel need to carefully test and slowly find the foothold. This way of working poses a great safety hazard.
[0005] 3. Since the bottom of the cabin is an inclined surface, the depth of the ladder at the bottom is very shallow. When an adult steps on it, only the forefoot can barely step on the ladder. After stepping on it, the toes just hit the inclined surface of the cabin, which makes it easy to slip.
[0006] 4. The existing ladder has no restriction device, so anyone can climb to the top of the cabin through the ladder. Since the existing ladder is used by professional maintenance personnel, there are great safety hazards for non-professional maintenance personnel when using the ladder. Utility Model Content
[0007] The technical task of the utility model is to provide a prefabricated cabin with a ladder with a handle structure in view of the deficiencies of the above prior art.
[0008] The technical solution adopted by the utility model to solve its technical problems is: a prefabricated cabin with a ladder with a handle structure, comprising a cabin body and a ladder, wherein the ladder is composed of an upper ladder and a plurality of lower ladders, a pair of bases are arranged on the top of the cabin body, the front end of the upper ladder is connected to the base, and support frames are arranged at the end of the upper ladder and the front end of the lower ladder, the support frame is composed of two support rods and a limit rod, the two ends of the limit rod are respectively connected to the ladder through a support rod, and an "L"-shaped insertion rod is arranged at the end of the lower ladder, the limit rod and the insertion rod are both connected to the cabin body through a connecting kit, and the connecting kit is composed of a support block and an "Ω"-shaped limit block, and the limit rod and the insertion rod are both located between the support block and the limit block.
[0009] Further improvement: the base is composed of two clamping blocks, a clamping plate is provided at the front end of the upper ladder, and the clamping plate is located between the two clamping blocks.
[0010] Further improvement: the support block is in an "n" shape, and a hook is provided on the limit rod.
[0011] Further improvement: a limiting plate is hinged on one side of any one of the lower ladders, and the other side of the limiting plate is locked to the other side of the lower ladder.
[0012] The advantages of the utility model are as follows: since the ladder and the cabin are separated, they can be painted separately, avoiding the problem of dead corners in painting, effectively solving the problem of corrosion caused by inadequate painting, and ensuring the safety of climbing; at the same time, the design of the ladder is not subject to the restrictions of prefabricated cabin transportation, so that the distance between the ladder and the cabin can be increased, thereby avoiding the problem of difficulty in landing and slipping during the up and down climbing process; finally, a locking limit plate is added to the ladder to effectively prevent non-professionals from using the ladder, avoiding the harm caused by the use of non-professionals.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.
[0020] As shown in the figure, a prefabricated cabin with a ladder with a handle structure includes a cabin body 1 and a ladder, wherein the ladder is composed of an upper ladder 2 and several lower ladders 3, a pair of bases 4 are provided on the top of the cabin body 1, the front end of the upper ladder 2 is connected to the base 4, and support frames 5 are provided at the end of the upper ladder 2 and the front end of the lower ladder 3, the support frame 5 is composed of two support rods 51 and a limit rod 52, the two ends of the limit rod 52 are respectively connected to the ladder through a support rod 51, and an "L"-shaped insertion rod 6 is provided at the end of the lower ladder 3, the limit rod 52 and the insertion rod 6 are both connected to the cabin body 1 through a connecting kit 7, and the connecting kit 7 is composed of a supporting block 71 and an "Ω"-shaped limit block 72, and the limit rod 52 and the insertion rod 6 are both located between the support block 71 and the limit block 72.
[0021] The base 4 is composed of two clamping blocks 41 . A clamping plate 21 is provided at the front end of the upper ladder 2 . The clamping plate 21 is located between the two clamping blocks 41 . Screw holes for bolt connection are provided on the clamping blocks 41 and the clamping plates 21 .
[0022] The support block 71 is in an "n" shape, and a hook 53 is provided on the limit rod 52. When installing the lower ladder 3, the lower ladder 3 is first hung on the support block 71 through the hook 53, and then the limit block 72 is fixed to the support block 71; finally, the upper limit plate 8 is hinged on one side of any one of the lower ladders 3, and the other side of the limit plate 8 is locked to the other side of the lower ladder 3.
[0023] Its working principle is: first, because the ladder and the cabin 1 are separate, the two can be carried out simultaneously during prefabrication, thereby shortening the overall process of prefabricating the cabin. The base 4 and the support block 71 are welded to the cabin 1 in advance, and the prepared ladder is placed in the cabin 1. After the cabin 1 is transported to the site, the ladder in the cabin is taken out. At this time, the workers will carry a ladder to facilitate the installation of the upper ladder 2 and the lower ladder 3 to the corresponding positions one by one.
[0024] When installing the ladder, the worker first places the ladder he carries on the cabin body 1, then fixes the front end of the upper ladder 2 to the base 4, and then hangs the end of the upper ladder 2 and all the lower ladders 3 on the support block 71 through the hook 53 on the support frame 5. At the same time, the insertion rod 6 at the end of the lower ladder 3 is also on the support block 71. Finally, the limit block 72 is fixedly connected to the support block 71 by bolts, and the limit rod 53 and the insertion rod 6 are fixed. In this way, the upper ladder 2 and the lower ladder 3 are fixed on the cabin body 1, and the upper ladder 2 and the lower ladder 3 form a complete ladder.
[0025] Finally, the limit plate 8 is connected to any lower ladder 3 or a position between two lower ladders 3 by a hinge, so that when the ladder is not in use, the limit plate 8 can be locked to prevent non-professionals from using the ladder.
[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
