Description

Technical Field

[0001] This invention patent relates to the field of maintenance tool technology, specifically to a quick-connect banana screen maintenance pedal. Background Technology

[0002] The banana screen is a core screening device in the coal washing and mineral sorting industry. The screen plates are subjected to continuous high-speed impact and wear from raw coal materials, requiring regular replacement and maintenance. Currently, during screen plate replacement and maintenance, workers generally use temporary steel pipe supports and makeshift base plates made of ordinary steel plates for high-altitude operations, which has many drawbacks: 1. The temporary support structure lacks reinforcement and cannot be reliably fixed to the banana screen frame, making it prone to overturning under equipment vibration or disturbance from personnel stepping on it; 2. The temporary base plate lacks a matching hook-and-hold structure, making it prone to slippage and detachment, increasing safety hazards at the work site; 3. The ordinary plate structure is not designed with the strength required for maintenance loads, resulting in insufficient capacity to support personnel and maintenance equipment, and poor structural stability; In addition, this type of temporary tooling requires on-site assembly and debugging, which takes a long time to prepare, seriously slowing down the efficiency of screen plate disassembly and maintenance, and restricting the production line downtime for maintenance. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a quick-connect banana screen maintenance pedal, the specific technical solution of which is as follows: A quick-connect banana screen maintenance pedal, for hanging on the frame beam of the banana screen, includes a base plate, a connecting rod, and a hanging unit; the connecting rod is vertically set in the middle of one side edge of the top of the base plate; the hanging unit is set at the top of the connecting rod.

[0004] Preferably, two angular ribs are symmetrically arranged on the left and right sides of the connecting rod.

[0005] Preferably, the bottom surface of the base plate is provided with reinforcing ribs arranged in a cross pattern; the reinforcing ribs are made of round steel bars with a diameter of 8mm.

[0006] Preferably, the base plate is made of steel plate with a thickness of not less than 5mm.

[0007] Preferably, the connecting rod is made of a round steel bar with a diameter of 10mm.

[0008] Preferably, the hanging unit has a U-shaped structure and is made by bending a round steel bar with a diameter of 10mm; the length of the two wing rods on both sides of the hanging unit is not less than 250mm.

[0009] Preferably, the external dimensions of the hanging unit are adapted to the outline dimensions of the hanging part of the banana screen frame beam.

[0010] More preferably, the connecting rod and the base plate, and the hanging unit and the connecting rod are all fully welded together.

[0011] The beneficial effects of this invention are: 1. This invention has strong stability, with cross reinforcing ribs arranged on the lower surface of the base plate, effectively avoiding the risk of the pedal tipping over during maintenance; 2. This invention, by setting a U-shaped hanging unit that is compatible with the banana screen frame beam, can be quickly hung and fixed without the risk of slippage; 3. The angular ribs symmetrically arranged on both sides of the connecting rod of the present invention have a dual function: on the one hand, they can strengthen the connection between the connecting rod and the base plate, improve the overall structural strength, and prevent the weld from breaking under stress; on the other hand, the plane of the rib can closely fit the side wall of the frame beam to form a lateral limiting structure, constrain the lateral displacement of the connecting rod, and effectively limit the left and right swing and lateral sliding of the pedal. 4. The present invention can adjust the size of the banana screen frame beam according to different models, without the need to set up temporary tools on site. It can be used directly by hanging, which simplifies the preparation process for maintenance work and improves work efficiency. Attached Figure Description

[0012] The accompanying drawings constituting this invention are provided to further understand this application and do not constitute an undue limitation of this application.

[0013] Figure 1 This is a schematic diagram of the overall structure of the present invention; In the diagram, 1 is the base plate; 2 is the connecting rod; 3 is the angular rib plate; and 4 is the hanging unit. Detailed Implementation

[0014] The specific implementation of a quick-connect banana screen maintenance pedal provided by the present invention will be further described with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown, a quick-connect banana screen maintenance pedal, used for hanging on the frame beam of the banana screen, includes a base plate 1, a connecting rod 2, and a hanging unit 4. The connecting rod 2 is vertically positioned at the middle of one side edge of the top of the base plate 1; the hanging unit 4 is located at the top of the connecting rod 2.

[0016] Preferably, two angular ribs 3 are symmetrically arranged on the left and right sides of the connecting rod 2. On the one hand, they can strengthen the connection between the connecting rod 2 and the base plate 1, improve the overall structural strength of the pedal, and prevent the weld from breaking under stress. On the other hand, the angular ribs 3 can also fit tightly against the side wall of the banana screen frame beam to form a lateral limiting structure, constrain the lateral displacement of the connecting rod 2, effectively limit the left and right swing and lateral sliding of the pedal, and improve the overall stability of the maintenance operation.

[0017] Preferably, the lower surface of the base plate 1 is provided with reinforcing ribs (not shown in the figure) to enhance the supporting strength of the base plate 1.

[0018] Preferably, the base plate 1 is made of steel plate with a thickness of not less than 5mm; the reinforcing rib is made of round steel bar with a diameter of 8mm; and the connecting rod 2 is made of round steel bar with a diameter of 10mm.

[0019] Preferably, the hanging unit 4 has a U-shaped structure and is made of round steel bars with a diameter of 10mm bent; the length of the two side wing rods of the hanging unit 4 is not less than 250mm to ensure sufficient overlap length and prevent the hanging unit 4 from detaching from the frame beam during maintenance due to the wing rods being too short.

[0020] In order to improve the connection stability between the pedal and the banana screen frame beam and reduce the displacement and shaking of the pedal during maintenance, the external dimensions of the hanging unit 4 are adapted to the outline dimensions of the hanging part of the banana screen frame beam.

[0021] It is worth noting that various standard sizes of pedals can be prefabricated based on the actual external dimensions of different frame beams to fit the frame beams of different models of banana screens.

[0022] More preferably, the connection between the connecting rod 2 and the base plate 1, and the connection between the hanging unit 4 and the connecting rod 2, are all made by full welding.

[0023] When in use, depending on the specific location of the maintenance point, maintenance personnel only need to hang several U-shaped mounting units 4 of the pedals on the corresponding frame beams of the banana screen to ensure that the base plate 1 remains in a horizontal support state. Maintenance personnel can then stand on the surface of the base plate 1 to perform screen plate maintenance or replacement operations.

[0024] This invention has a simple structure and is easy to assemble and disassemble. It can be quickly attached to the banana screen frame to avoid swaying and tipping. Its load-bearing capacity meets the maintenance requirements, simplifies the operation process, and improves maintenance safety and efficiency.
