Description

Technical Field

[0001] The utility model relates to a warehouse high-altitude working device, in particular to a suspended high-altitude mobile working device used for the construction of the inner wall of a large-volume warehouse. Background Art

[0002] During the construction of the blast furnace ironmaking section, the rust removal, anti-corrosion, and wear-resistant lining of the inner walls of large silos such as silos, coal silos, and dust collection silos are often involved. During the construction process, construction materials and machinery are transferred to the interior of the silo through ropes. However, due to the limited space in the silo, materials and machinery can only be transferred in small quantities each time when they are sent to the construction area through the full-hall scaffolding, and the construction efficiency is extremely low. The workers' work inside the silo is considered high-altitude work, and they shuttle between the racks and pipes where tools and materials are placed, which poses a risk of falling for both workers and materials. After the construction of each silo is completed, all the scaffolding in the silo needs to be dismantled and transferred to another silo for re-erection. The large-scale use and transportation of turnover materials leads to increased costs.

[0003] The traditional practice is to set up a full-floor scaffolding, but because the bottom of most warehouses is not flat, the scaffolding is not stable. In order to ensure the working space of the construction workers, a springboard should be set up on the scaffolding close to the warehouse wall, but because the construction tools and materials need to be placed, the working space for the workers is still not large. The transportation of construction materials, rack pipes and other tools is carried out by ropes in small quantities and multiple times to the inside of the warehouse, which requires at least two people to cooperate. The labor cost is high, the construction efficiency is very low, and there is a risk of falling of people and materials. Because the turnover materials take up a lot of space, several connected warehouses cannot be constructed at the same time, and can only be constructed one by one or a few warehouses at the same time. When the construction of each warehouse is completed and transferred to another warehouse for construction, the dismantled scaffolding pipes need to be taken out one by one by a crane or tower crane and placed in other warehouses. The construction efficiency is not high. Some projects do not have the conditions for arranging tower cranes. At the same time, because the warehouse is too high, the cost of using a crane is too high, so manual transportation will be chosen. However, although manual transportation saves machinery costs, labor costs increase sharply, and the cost savings are not significant. Utility Model Content

[0004] The purpose of the utility model is to provide a suspended high-altitude mobile working device for the construction of the inner wall of a large-volume warehouse, so as to solve the problems of low efficiency, high safety risks and high material turnover cost in the existing high-altitude construction of the inner wall of the warehouse.

[0005] The utility model is implemented as follows: a suspended high-altitude mobile working device for the construction of the inner wall of a large-volume silo comprises a guide rail, a hanging bracket, a leg, a hanging adjustment mechanism and an operating platform, wherein the guide rail is arranged on the top platform of the silo, and the guide rail is located on both sides of the silo, the leg is located at the lower part of both sides of the hanging bracket, rollers are arranged at the lower ends of the legs, the rollers are located on the guide rails, the operating platform is located below the hanging bracket, and the operating platform is connected to the hanging bracket through the hanging adjustment mechanism, the outline of the operating platform is a circle with a diameter smaller than the diameter of the silo, and the hanging adjustment mechanism is used to adjust the height of the operating platform.

[0006] As a further improvement of the suspended high-altitude mobile working device of the utility model for the construction of the inner wall of a large-volume warehouse, the hanging bracket is a rectangular frame structure, including a rectangular bracket main beam and bracket secondary beams that intersect each other in the rectangular space of the bracket main beam.

[0007] As a further improvement of the suspended high-altitude mobile working device of the utility model used for the inner wall construction of a large-volume warehouse, a plurality of detachable lifting ears are arranged on the hanging bracket, and the detachable lifting ears are used to suspend the hanging adjustment mechanism, and the two ends of the detachable lifting ears are fixed to the hanging bracket by bolts.

[0010] As a further improvement of the suspended high-altitude mobile working device used for the inner wall construction of a large-volume warehouse, the utility model also includes a limit weight hammer for limiting the minimum distance between the hanging bracket and the operating platform.

[0012] The utility model is used for the inner wall construction of large-volume silo. The operating platform is suspended on the hanging bracket by a hanging adjustment mechanism. The hanging adjustment mechanism can control the height of the operating platform and lower the operating platform into the silo. The operator can perform rust removal, anti-corrosion, and laying of wear-resistant lining plates on the silo wall on the operating platform without setting up a full-floor scaffolding. The operator can quickly and easily reach the corresponding construction height of the silo wall, thereby improving the efficiency and safety of the construction.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0023] like Figure 1As shown, the utility model is a suspended high-altitude mobile working device used for the construction of the inner wall of a large-volume warehouse, including a guide rail 3, a hanging bracket 4, a leg 5, a hanging adjustment mechanism 8 and an operating platform 9.

[0024] like Figure 2 As shown, the guide rails 3 are arranged on the top platform of the silo 1, the guide rails 3 are located on both sides of the silo, and the direction of the guide rails 3 is parallel to the direction of the connection line of a row of silos 1. The suspended high-altitude mobile working device of the utility model is installed on two guide rails 3, and the hanging bracket 4 spans above the silo 1. When the suspended high-altitude mobile working device moves along the guide rails 3, the hanging bracket 4 can pass through all the silos 1 in this row. The guide rails 3 facilitate the horizontal movement of the device between continuous silos, reduce the cost of moving the device, and improve work efficiency.

[0025] like Figure 6 As shown, the hanging bracket 4 is a rectangular frame structure, including a bracket main beam 4-1 and a bracket secondary beam 4-2. The bracket main beam 4-1 forms a rectangular structure, and the bracket secondary beam 4-2 is located in the rectangular space surrounded by the bracket main beam 4-1, and a plurality of bracket main beams 4-1 intersect each other to form a grid structure. Among them, the bracket main beam 4-1 and the bracket secondary beam 4-2 are both I-beams, and the bracket main beam 4-1 and the bracket secondary beam 4-2 are connected and fixed by welding.

[0026] The front and rear ends of the bracket main beam 4-1 located on both sides of the hanging bracket 4 extend outward, and the extended part is used to connect the supporting legs 5. The installation position of the supporting legs 5 can be determined according to the size of the silo.

[0027] The legs 5 are located at the lower part of both sides of the hanging bracket 4 . Rollers 6 are provided at the lower ends of the legs 5 . The rollers 6 are located on the guide rails 3 . The hanging bracket 4 is moved along the guide rails 3 by the rollers 6 .

[0028] like Figure 4 As shown, the top of the leg 5 is fixed to the support beam of the hanging bracket 4 by bolts.

[0029] like Figure 5 As shown, the guide rail 3 can be a triangular guide rail 3 or a U-shaped guide rail 3, etc. The guide rail 3 is fixed to the top platform of the silo 1 by bolts, and the roller 6 is axially connected to the lower end of the support leg 5, and the roller 6 and the guide rail 3 cooperate and contact with each other.

[0030] The operating platform 9 is located below the hanging bracket 4, and the operating platform 9 is connected to the hanging bracket 4 through a hanging adjustment mechanism 8, and the height of the operating platform 9 can be adjusted through the hanging adjustment mechanism 8. The outline of the operating platform 9 is a circle with a diameter smaller than the diameter of the silo 1, so that when the operating platform 9 moves to the top of the silo 1, the operating platform 9 can be lowered into the silo 1 through the hanging adjustment mechanism 8.

[0031] like Figure 3 As shown, a plurality of detachable lifting ears 7 are provided on the hanging bracket 4, and the detachable lifting ears 7 are used to hang the hanging adjustment mechanism 8, and both ends of the detachable lifting ears 7 are fixed to the bracket main beam 4-1 or the bracket secondary beam 4-2 of the hanging bracket 4 by bolts.

[0032] Uniform bolt holes are respectively arranged on the bracket main beam 4-1 and the bracket secondary beam 4-2 of the suspension bracket, and corresponding bolt holes are selected as needed to connect the detachable lifting lugs 7. The device can be adapted to the construction of the inner wall of the warehouse with different diameters, thereby increasing the application range of the device.

[0033] The hanging adjustment mechanism 8 is an electric hoist, which is connected to a hook on the detachable lifting ear 7, and drives the operating platform 9 to move up and down through the electric hoist.

[0034] The electric hoist suspends the operating platform 9 through the steel wire rope 12, making the working space more spacious. There are no other obstacles on the operating platform 9 except the steel wire rope 12, and the material transportation and storage as well as the movement of the operators are safer.

[0035] like Figure 7 As shown, the operating platform 9 includes a plurality of cross-arranged platform main beams 9 - 1 , rack pipes 9 - 2 are arranged between the platform main beams 9 - 1 , and a springboard is laid on the edge of the operating platform 9 .

[0036] The platform main beam 9-1 is an I-beam, and the frame pipe 9-2 is a steel pipe. According to the size of the silo 1, the platform main beam 9-1 can be appropriately reduced or expanded by cutting, welding, etc., so that it has a stronger applicability.

[0037] Several suspension points are arranged on the platform main beam 9-1, and the suspension points are used to connect with the suspension adjustment mechanism 8. The suspension of the operating platform 9 is realized by several suspension adjustment mechanisms 8, and the number and distribution position of the suspension adjustment mechanisms 8 are determined according to needs to ensure the stability and bearing capacity of the operating platform 9.

[0038] The utility model further includes a controller 11, which is fixedly mounted on the hanging bracket 4 or the leg 5. All electric hoists are electrically connected to the controller 11, and the controller 11 controls all electric hoists to achieve synchronous lifting. This ensures that the lifting and lowering actions of the electric hoists are unified, and enhances the stability and reliability of the device. The controller 11 can be controlled by wireless remote control.

[0039] In order to ensure safety, the utility model also includes a limit weight 10, which is a limit switch device of the electric hoist. The limit weight 10 is set on the hanging bracket 4 or the electric hoist, and is used to limit the minimum distance between the hanging bracket 4 and the operating platform 9. When the operator adjusts the height of the operating platform 9 through the controller 11, he should pay attention to the distance between the limit weight 10 and the operating platform 9. When the operating platform 9 contacts the limit weight 10, the electric hoist automatically stops moving to prevent the distance between the operating platform 9 and the hanging bracket from being too small.

[0040] According to the size of the silo, the utility model sets a suspended high-altitude mobile working device on the silo roof platform 2 on the top of the silo, and uses the device to complete the construction operations such as rust removal, corrosion prevention, and laying of wear-resistant lining plates on the inner wall of the silo 1.

[0041] According to the size of the silo 1, the operating platform 9 is first made on the ground, the ring beam and the platform main beam 9-1 are welded and the hanging points are evenly set. At the same time, the pipe rack 9-2 and the springboard can be laid.

[0042] At the same time, the hanging bracket 4 of appropriate size can be spliced ​​by calculation, the bracket main beam 4-1 can be spliced, and the steel legs 5 and the hanging bracket 4 can be connected and fixed by bolts and nuts. Then the detachable lifting lug 7 is fixed to the hanging bracket 4 by bolts and nuts. Then the roller 6, electric hoist, controller 11, limit weight 10, wire rope 12 and other components are installed to the corresponding positions respectively.

[0043] After the guide rail 3 is hoisted to the silo roof platform 2 and installed and fixed by mechanical equipment such as a crane or an overhead crane, the above-mentioned parts assembled on the ground are hoisted to the silo roof platform 2 for final assembly and the entire device is debugged before being put into use.

[0044] After the suspended high-altitude mobile operation system is installed on the top of the silo, the operation platform 9 is lifted to the same height as the silo top platform 2 through the controller 11, and the construction materials and construction tools of the day are transported to the operation platform 9 by manual transportation. After that, the construction personnel operate the controller 11 through the wireless remote control to lower the operation platform 9 to the position where the operation is required inside the silo 1, so as to complete the construction work of the day. If it is necessary to add construction materials, construction tools or adjust the working position of the inner wall of the silo 1 during the construction process, the operation platform 9 can be repeatedly raised and lowered to achieve the purpose.

[0045] When the inner wall construction of the first silo 1 is completed, the operating platform 9 is lifted to a level above the silo top, and the device is translated to the top of the second silo 1 through the rollers 6 and the guide rails 3 to start the construction of the second silo 1.

[0046] When the construction of each set of continuous inner walls of the warehouse is completed, the size of the device can be changed by adjusting the number and position of the detachable lifting ears 7, adjusting the position and size of the platform main beam 9-1, the frame pipe 9-2 and the springboard on the operating platform 9, and adjusting the position of the support legs 5. Then, the device can be transferred to the top of other warehouses by a crane or a crane to continue the construction work.

[0047] The utility model can fundamentally solve the problem of excessively high material and labor costs caused by the large-scale use of turnover materials and repeated erection and dismantling during the construction of the inner wall of a large-volume warehouse. It also solves the problems of many obstacles in the material and tool transportation channel and inconvenient personnel movement caused by the small working space. It increases the working space to make the transportation and storage of materials and the movement of operators safer while also improving work efficiency. At the same time, the device also has the characteristics of easy erection and dismantling, easy size adjustment, up and down movement, and front and back movement, and is suitable for the construction of the inner wall of warehouses with different diameters. Only a small amount of modification and adjustment is required for each use, and it does not need to be manufactured from scratch, saving a lot of material costs, labor costs and time costs.
