Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting telescopic machine. Background Art

[0002] For large conveyor lines between warehouses, they generally have to pass through the fire shutter doors corresponding to the warehouses. Since the belt conveyors corresponding to the conveyor lines will interfere with the closing of the fire shutter doors, the belt conveyors need to be manually retracted before the shutter doors are closed. This undoubtedly poses certain safety hazards. In the event of a fire hazard, there will be corresponding safety problems if the fire shutter doors cannot be closed in time.

[0003] Therefore, we propose a fire-fighting telescopic machine to solve the above problems. Utility Model Content

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0022] According to one embodiment of the present invention, Figure 1-Figure 5 Shown.

[0023] In this embodiment, as for the overall structure, a fire-fighting telescopic machine includes: an open welding frame 1, a driving member 2 fixed on the welding frame 1, a fuselage 3 connected in a sliding direction of the opening of the welding frame 1, a transmission chain 4 and a belt module 5 symmetrically arranged on the inner walls of both ends of the welding frame 1, the driving member 2 is used to servo-drive the transmission chain 4 to rotate, the side end of the fuselage 3 is connected and fixed to the transmission chain 4 through a fixing plate 8, and the belt module 5 is fixed on the welding frame 1. It is a U-shaped tensioning structure and one end can be telescopic.

[0024] Specifically, if Figure 1 As shown, for the welding frame 1, in this embodiment, the welding frame 1 includes two horizontal plates 101 relatively arranged, a vertical plate 102 symmetrical with the center of the horizontal plate 101 and welded to the end of the horizontal plate 101, and a slide 103. Support legs 104 are fixed at both ends of the bottom of each horizontal plate 101. The slide 103 is set in the direction of the opening of the welding frame 1, and includes two and respectively fixed on the vertical plates 102. The two ends of the fuselage 3 are respectively rolled and mounted on the upper and lower sides of the slide 103 through a plurality of continuous guide wheels 105.

[0025] There are actually multiple options for the driving member 2. In this embodiment, the two vertical plates 102 are rotatably connected to the transmission roller 106 at both ends of the corresponding transmission chain 4. The driving member 2 includes a first motor 201, a support 202 and a first synchronous chain 203. The first motor 201 is welded to the welding frame 1 through the support 202. One end of the first synchronous chain 203 is engaged with the output end gear of the first motor 201, and the other end is engaged with the gear of the transmission roller 106.

[0026] Through the above structure, after the first motor 201 servo outputs, the transmission roller 106 is driven to rotate through the first synchronous chain 203, and the transmission chain 4 follows the synchronous rotation, and then the fuselage 3 is clamped and slid on the slide 103 through the fixed plate 8, and finally the fuselage 3 is telescoped back and forth at the open end of the welding frame 1 to correspond to the operation of the external warehouse transportation line. When the fuselage 3 is retracted, it does not affect the closing of the external fire roller shutter telescopic door, which is practical and convenient.

[0027] like Figure 2 and Figure 3 As shown, the belt module 5 includes a second motor 501, a reducer 502, a second synchronous chain 503, an active roller 504 and a driven roller 505. The second motor 501 is welded to the welding frame 1, and its output end is decelerated and output through the reducer 502 and then meshes with the gear at one end of the second synchronous chain 503. The active roller 504 is rotatably connected to the two vertical plates 102, and the driven roller 505 is rotatably connected to the fuselage 3. A belt 506 is tensioned on the active roller 504 and the driven roller 505.

[0028] The belt 506 is further provided with a limiting roller 508 and a tensioning roller 507 on the side corresponding to the vertical plate 102. The tensioning roller 507 is located below the same side of the active roller 504 and is rotatably connected to the two vertical plates 102. The limiting roller 508 is located in the middle of the vertical plates 102 and is located between the tensioning roller 507 and the active roller 504 in the height direction. The vertical plate 102 is provided with a horizontal limiting groove corresponding to the limiting roller 508 and is slidably connected to the limiting roller 508 through the limiting groove.

[0029] In order to realize the telescopic external connection of the belt 506 in conjunction with the sliding of the fuselage 3, the present application takes into account the change in the extension amount of the belt 506, and thus adds a limiting roller 508 and a tensioning roller 507 at the corresponding position of the vertical plate 102. Figure 4 and Figure 5 When the length of the belt 506 at the deep end of the fuselage 3 changes, the limiting roller 508 is compensated by sliding in the corresponding length limiting groove, and the tensioning roller 507 is used to simultaneously tighten the belt 506, ultimately realizing the telescopic docking operation of the transport line goods.

[0030] In some embodiments, the maximum telescopic length of the belt module 5 is 1000 mm, and the length of the limiting groove is set correspondingly thereto.

[0031] Similarly, to ensure the stability of the cargo transportation process of the conveyor line, an outer guardrail 6 is welded to the top of each vertical plate 102. The outer guardrail 6 is embedded with an inner guardrail 7. One end of the inner guardrail 7 is exposed and welded to the external maintenance platform connecting piece 11. The inner and outer guardrails can prevent cargo from falling, which is practical and reliable.

[0032] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
