[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0034] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0035] When a metallurgical overhead crane is feeding steel into a steelmaking furnace, the driver's cab faces the furnace mouth, and the slag in the furnace easily splashes onto the glass of the driver's cab. This high-temperature slag easily burns the window glass of the driver's cab, causing safety risks to the driver and the internal equipment.

[0036] To this end, an embodiment of the present application provides a metallurgical bridge crane cab and an anti-splash safety protection device thereof, which aims to improve the cab's ability to resist erosion by splashing slag to a certain extent and reduce the risk of injury to personnel and equipment in the cab.

[0037] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to resist the impact and erosion of the splashing high-temperature slag, a buffer protection device can be set on the front side of the driver's cab of the metallurgical bridge crane to prevent the impact and erosion of the high-temperature splashing slag while taking visibility into consideration.

[0038] Specifically, the splash-proof safety protection device for the driver's cab of a metallurgical bridge crane may include: a support frame 1, a guide rail 2, a protection net 3, and a lifting mechanism 4. The guide rail 2 is arranged on the support frame 1, the protection net 3 is a buffer protection member, which is slidably connected to the guide rail 2, and the lifting mechanism 4 is connected to the protection net 3 to drive the protection net 3 to reciprocate along the guide rail 2.

[0039] The support frame 1 is the support and installation base of the entire anti-splash safety protection device. On the one hand, it supports some other components, and on the other hand, the entire anti-splash safety protection device can be installed on the driver's cab 7. Generally speaking, a mounting portion can be set on the support frame 1 for corresponding installation on the driver's cab 7. Fasteners can be used for detachable installation, and welding can also be used to achieve stable fixation.

[0040] There are two guide rails 2, which are arranged in parallel on the support frame 1, and the spacing between the two guide rails 2 is greater than the width of the window glass 71 of the driver's cab 7, and the guiding direction of the two guide rails 2 is vertical; the protective net 3 is slidably connected between the two guide rails 2, and the protective net 3 is arranged in front of the driver's cab window, so as to move to the front side of the driver's cab to block the window glass 71, block and buffer the splashed slag and maintain a certain field of view through the grid gap of the protective net 3, or expose the window glass 71 to maintain a normal field of view.

[0041] The lifting mechanism 4 is a displacement driving mechanism of the protective net 3, which can be set on the top of the driver's cab 7, and the lifting mechanism 4 is connected to the protective net 3. With the driver's cab 7 as the force basis, the protective net 3 is driven to reciprocate along the guide rail 2 to cover or expose the window glass 71.

[0042] It is worth noting that the protective net 3 can be moved vertically up and down, so that when the driver's cab is opposite to the furnace mouth, the protective net 3 can be moved to the front side of the driver's cab, that is, set between the window glass 71 of the driver's cab 7 and the furnace mouth to form a buffer blocking structure; on the other hand, the protective net 3 has a certain light transmittance and a certain field of view, which can meet the needs of observing the furnace mouth during the charging process. The operating end of the lifting mechanism 4 can be set in the driver's cab 7 for the driver to operate conveniently.

[0043] In some embodiments, in order to improve the movement reliability of the protective net 3, vertically extending limiting grooves can be provided on the opposite sides of the two guide rails 2, and the side edges of the protective net 3 can be slidably embedded in the limiting grooves, thereby limiting the movement of the protective net 3 and preventing it from getting out of place.

[0044] In some embodiments, in order to improve the smoothness of movement of the protective net 3, the splash-proof safety protection device of the driver's cab of the metallurgical bridge crane may also include a plurality of roller groups, and the plurality of roller groups are respectively installed on the edges on both sides of the protective net 3, and the plurality of roller groups are respectively embedded in the limiting slide grooves on the corresponding sides, so as to reduce contact friction through the roller groups and ensure smooth movement.

[0045] In some embodiments, the number of the roller groups can be set to four groups, the protection net 3 is rectangular, and the four roller groups are respectively arranged at the four corners of the protection net 3. Of course, other shapes are not excluded, and no specific limitation is made here.

[0046] In some embodiments, in order to balance light visibility and structural strength, the protective net 3 may include: a steel frame 31 and a grid plate 32; the steel frame 31 is a ring frame, the grid plate 32 is arranged in the steel frame 31, and the edge of the steel frame 31 can be slidably arranged in the limiting slide groove.

[0047] That is, the grid plate 32 can be embedded in the inner side of the steel frame 31, and the grid plate 32 can be installed by welding or fixing with fasteners.

[0048] Generally speaking, the grid plate 32 should have a certain strength to withstand impact, and also have a certain heat resistance, such as a steel mesh.

[0049] In some embodiments, in order to realize automatic lifting of the protective net 3 and adapt to the high temperature and dust conditions of steelmaking conditions, the lifting mechanism 4 can adopt a traction rope traction structure to realize the lifting and lowering drive of the protective net 3.

[0050] Specifically, the lifting mechanism 4 may include: a driving motor 41 , a reducer 42 , a wire wheel 43 , a supporting pulley 44 and a traction rope 45 .

[0051] The driving motor 41 and the reducer 42 can be used as a power mechanism and can be arranged on the top of the driver's cab 7. The driving motor 41 and the reducer 42 can be connected, and the wire wheel 43 is sleeved on the output shaft of the reducer 42; the supporting pulley 44 is arranged at the top of the guide rail 2, and the first end of the traction rope 45 is wound around the wire wheel 43, and the second end bypasses the supporting pulley 44 and is connected to the protective net 3, so that when the driving motor 41 drives the wire wheel 43 to rotate, the protective net 3 is driven to move up and down to cover or expose the window glass 71 of the driver's cab 7.

[0052] It is worth noting that, through the cooperation between the traction rope 45, the support pulley 44 and the wire wheel 43, stable transmission can be maintained in a high temperature environment.

[0053] In some embodiments, in order to facilitate operation, the metallurgical bridge crane driver's cab splash protection device also includes an operation controller, and the operation controller is connected to the drive motor 41.

[0054] Generally speaking, the operation controller can adopt a typical motor controller, and be equipped with control devices with electrical signals such as opening and closing buttons and operating levers to realize the control of the drive motor 41. The control end of the drive motor 41 can also be integrated into the control system in the cab 7 of the metallurgical bridge crane, and control buttons or operating levers can be brought out to realize control. When implementing the lifting control of the protective net 3, the corresponding buttons or operating levers can be operated.

[0055] In some embodiments, in order to ensure the accuracy of the protective net 3, the splash-proof safety protection device of the driver's cab of the metallurgical bridge crane may also include a limit switch. The limit switch is divided into two groups, which are respectively arranged at the top and bottom of the guide rail 2 and are respectively connected to the operation controller to monitor the position of the protective net 3 and control the start and stop status of the protective net 3.

[0056] That is, after the protective net 3 moves to the front side of the window glass 71 of the driver's cab 7 and is in place, an arrival signal is triggered, and the operation controller controls the drive motor 41 to stop based on the trigger signal; or after the protective net 3 leaves the front side of the window glass 71 of the driver's cab 7 and is in place, an arrival signal is triggered, and the operation controller controls the drive motor 41 to stop based on the trigger signal.

[0057] On the other hand, an embodiment of the present application provides a metallurgical bridge crane cab, comprising: a cab body and the metallurgical bridge crane cab splash-proof safety protection device; the mounting portion of the support frame is welded to the cab body, and the protective net 3 is arranged on the front side of the cab window.

[0058] In some embodiments, the distance between the protective net and the window glass of the driver's cab body is greater than 20 centimeters to maintain a stable protective effect.
