Description

Technical Field

[0001] The utility model relates to the field of ladder lifting equipment, in particular to an automatic lifting device for a vertical ladder in an integrated pipe gallery. Background Art

[0002] A comprehensive pipeline corridor is a relatively closed linear underground structure that accommodates urban engineering pipelines. The comprehensive pipeline corridors currently planned and constructed are mainly "full-section" comprehensive pipeline corridors. Concrete corridors are built along the entire line of the pipeline corridor, and the entire line is equipped with ancillary facilities such as ventilation, fire protection, and lighting. The "full-section" comprehensive pipeline corridor can meet the maintenance and operation requirements of the entire comprehensive pipeline corridor.

[0003] The construction of concrete corridors along the entire line makes the construction of the corridor itself very expensive; and the "full-section" integrated corridor has a huge cross-section and high construction standards, especially the cost of soil, dredging and protection for the construction of the corridor, which makes the construction of the integrated corridor difficult.

[0004] Due to the limited space in the current integrated pipeline corridor, simple steel vertical ladders are often used between the pipeline corridor layer, equipment layer and the ground. It is laborious and inconvenient for people to go up and down, and it is also inconvenient to transport small goods up and down. An automatic lifting device for the vertical ladder of the integrated pipeline corridor is needed to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic lifting device for a vertical ladder in an integrated pipe gallery, which has vertical transportation capabilities, is safe and efficient, and can effectively reduce the workload of inspection personnel.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] An automatic lifting device for a vertical ladder in a comprehensive pipe gallery, comprising:

[0008] The main body of the pipe gallery has entrances and exits at the top;

[0009] The main body of the ladder is on the same vertical line as the entrance and exit;

[0010] The lifting assembly is installed inside the main body of the pipe gallery and is used to drive the longitudinal movement of the main body of the ladder;

[0011] Among them, a moving block is installed on the lifting assembly, a connecting block is provided on the ladder body, the moving block is fixedly connected to the connecting block, a protective door is installed on the front side of the ladder body, and a plurality of blocks are also fixed on the rear side of the ladder body.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] Through the cooperation of the motor, sliding block and wire rope in the lifting assembly, the sliding block slides in the sliding rail, thereby ensuring the stability of the moving block's up and down lifting, and then the standing platform is used to realize the up and down lifting of people and small goods, which is safe and efficient, and reduces the workload of inspection personnel.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-3 The figure shows an embodiment of an automatic lifting device for vertical ladders in a comprehensive pipe gallery provided by the present invention:

[0020] An automatic lifting device for a vertical ladder in a comprehensive pipe gallery, comprising:

[0021] The main body of the pipe gallery 1 has an entrance and exit 2 at the top;

[0022] The main body 3 of the ladder is on the same vertical line as the entrance 2;

[0023] The lifting assembly 4 is installed inside the pipe gallery body 1 and is used to drive the ladder body 3 to move longitudinally;

[0024] Among them, a moving block 5 is installed on the lifting assembly 4, and a connecting block 6 is provided on the ladder body 3. The moving block 5 is fixedly connected to the connecting block 6. A protective door 7 is installed on the front side of the ladder body 3 to protect people and goods during the lifting process and prevent safety hazards. A plurality of blocks 8 are also fixed on the rear side of the ladder body 3.

[0025] It should be noted that the entrance and exit 2 is large enough to allow the ladder body 3 to pass through.

[0026] The lifting assembly 4 includes a motor 41 and two sliding rails 42 provided on the left and right sides of the motor 41. A first roller 43 is sleeved on the output end of the motor 41. A second roller 44 is rotatably provided above the first roller 43. A steel wire rope 45 is connected between the first roller 43 and the second roller 44.

[0027] Furthermore, the lifting assembly 4 also includes a motor fixing seat and a second roller fixing seat, the motor 41 is fixedly mounted on the motor fixing seat, and the motor fixing seat is fixed in the pipe gallery body 1, the second roller 44 is fixedly mounted on the second roller fixing seat, and the second roller fixing seat is fixed in the pipe gallery body 1.

[0028] Sliding blocks 46 are slidably provided in the two sliding rails 42 , and the left and right ends of the moving block 5 are respectively connected to the two sliding blocks 46 , and the steel wire rope 45 is transmission-connected to the moving block 5 for pulling the moving block 5 to move up and down longitudinally.

[0029] Connectors 9 are provided at both ends of the steel wire rope 45 , and the two connectors 9 are detachably fixed to the top and bottom sides of the moving block 5 .

[0030] Furthermore, the connecting member 9 can be a mechanical connecting member such as a bolt or a shackle. When the connecting member 9 is a bolt, a corresponding screw hole is provided on the moving block 5. When the connecting member 9 is a shackle, a corresponding buckle is provided on the connecting member 9.

[0031] The lifting assembly 4 also includes a back plate 47 arranged between the moving block 5 and the sliding rail 42. The back plate 47 has two grooves 48 corresponding to the two sliding rails 42. The moving block 5 is connected to the sliding block 46 through the grooves 48. The back plate 47 also has a longitudinally extending connecting groove 49. The connecting member 9 is connected to the moving block 5 via the connecting groove 49.

[0032] The ladder body 3 includes a standing platform 31 and a ceiling 32 . Support columns 33 are connected between the standing platform 31 and the left and right sides of the ceiling 32 . A control panel 34 electrically connected to the motor 41 is installed on the support columns 33 .

[0033] The protective door 7 is rotatably connected to the front side of the ladder body 3, and a handle is installed on the protective door 7.

[0034] Furthermore, a plurality of stoppers 8 are arranged at intervals on the left and right sides of the rear side of the standing platform 31, and the spacing between the stoppers 8 is preferably 600 mm.

[0035] The working principle of this utility model is roughly as follows:

[0036] The first roller 43 is driven to rotate by the motor 41, and the first roller 43 is connected to the second roller 44 via a wire rope 45, thereby driving the wire rope 45 to move. The two ends of the wire rope 45 are respectively fixed to the top and bottom sides of the moving block 5 by a connecting piece 9. Therefore, the movement of the wire rope 45 will pull the moving block 5 to rise and fall longitudinally on the sliding block 46 in the sliding rail 42. The moving block 5 is fixedly connected to the ladder body 3 by the connecting block 6, so the rise and fall of the moving block 5 will drive the ladder body 3 to rise and fall together. The ladder body 3 is provided with a protective door 7, which can protect people and goods during the lifting process. At the same time, the rear side of the ladder body 3 is also provided with a plurality of blocks 8, and the blocks 8 are also for protecting people. The start and stop of the motor 41 can be controlled by operating the control panel 34 in the standing platform 31, thereby controlling the rise and fall of the ladder body 3, which is safe and efficient.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
