Description

Workbench for disassembling the motor}

This design relates to a workbench for motor disassembly, and more specifically, for regular inspection of medium-sized motors, a safety footrest and handrail are installed in a foldable manner on the workbench used for maintenance and disassembly work on the motor when installed in the operation building. Thus, the safety of workers can be secured, the worker's work space and movement line can be greatly expanded, and loss and damage can be prevented by separately storing disassembled and assembled safety scaffolding and handrails, as well as securing a separate space. This relates to a motor disassembly workbench designed to prevent costs and inconveniences due to such problems.

Generally, parts such as motor fans and couplings are assembled within a medium-sized or large-sized motor. During the planned preventive maintenance period, the internal parts are disassembled and reassembled to inspect the motor.

To disassemble and assemble motor parts, tools such as chain blocks and hydraulic cylinders are used. If the center of gravity of the part becomes unbalanced during the work process, a falling accident occurs, resulting in injury to workers and damage to machine parts. There was a problem.

Meanwhile, in the case of a workbench for disassembling large or medium-sized motors, it is installed in a work building related to regular inspection, and when servicing or disassembling a specific medium-sized motor, the work is carried out by placing it on top or standing it in the center of the workbench. Due to the high height, there is always a risk of falling and safety accidents as work is carried out using ladders, etc.

Accordingly, removable handrails, including safety footrests, are installed along the upper surface of the workbench or upper frame to secure work space as needed to ensure worker safety and work space.

However, in the case of most conventional motor disassembly workbenches, the safety footrest and handrail are manufactured separately from the workbench, stored in a specific location, and installed on the top or upper frame of the workbench for disassembly and assembly only when necessary.

In the conventional motor disassembly workbench with this configuration, the assembled safety footrest and handrail, which are manufactured and stored separately from the workbench main body, not only have the risk of being lost or damaged during storage or movement, but also require securing a separate storage space, transporting, disassembling, and assembling the workbench. There is a problem that the inconvenience caused is very large, as well as storage costs and labor costs are high.

Hereinafter, with reference to the attached drawings, the operating conditions according to each configuration, including preferred embodiments according to the present invention, will be described in detail as follows.

Figure 1 shows a partially exploded perspective view and a partially enlarged view of a workbench for disassembling a motor to which the present invention is applied, and Figure 2 shows a perspective view of a partially assembled state of a workbench for disassembling a motor to which the present invention is applied.

In addition, Figures 3 to 5 show perspective views of the motor disassembly workbench to which the present invention is applied when not in use and in a state in which only the safety footrest and the handrail are unfolded for use.

According to this, the motor disassembly workbench to which an embodiment of the present invention is applied, as shown in FIGS. 1 and 2, largely includes a base 10, a plurality of safety scaffolds 20, a plurality of handrails 30, and a plurality of scaffolds. It may have a configuration including a support 40.

At this time, the base portion 10 corresponds to the main function of the motor disassembly workbench to which the present invention is applied, that is, the main frame on which the pump subject to inspection and disassembly can be mounted, and includes an upper frame 11 and a plurality of legs. (12) and may include a plurality of bridge connection and reinforcing members (13).

In addition, among the components of the base 10, the upper frame 11 is an "H" beam or a rectangular shape with a thick thickness and a relatively wide width so as to sufficiently withstand the load of workers, etc., including the pump subject to inspection and disassembly. It can have a square frame shape with an opening in the center using pipes, etc.

In addition, the plurality of legs 12 are installed in a vertical direction at the bottom edge of the upper frame 11 and perform a pillar function for the entire motor disassembly workbench to which the present invention is applied.

These legs 12 include the load of the operator, including the pump subject to inspection and disassembly, as well as the upper frame 11, a plurality of safety scaffolds 20 and a plurality of scaffold supports 40, which will be described later, and the like. In order to sufficiently withstand all the load applied to the applied motor disassembly workbench, it can be installed by cutting an "H" beam or a thick square or circular pipe with a large width or diameter to the desired height.

In addition, the plurality of leg connecting and reinforcing members 13 have a shape installed horizontally between two adjacent legs 12 to interconnect adjacent legs among the legs 12, and are installed from the outside. It functions to reinforce the support and strength of the legs so that the upper frame 11, including the legs 12, does not shake or twist no matter what external force or load is applied.

These leg connection and reinforcement members 13 do not apply a large load compared to the upper frame 11 and the legs 12, and provide reinforcement for the connection function and support force for the legs 12. Since it performs the function, it can be made by cutting relatively small "H" beams or square or circular pipes to a certain length compared to the upper frame 11 and the legs 12 and installing them between adjacent legs.

Meanwhile, the plurality of safety footrests 20 have a shape in which a wire mesh 22 is installed on the upper surface of a frame 21 having a square frame shape, and one side (folded) is formed on each upper surface of the base 10. The upper surface when unfolded and the rear when unfolded may have a form rotatable within a range of 90 degrees as shown in FIGS. 3 to 5 through at least two footrest hinges 23.

At this time, the bottom of the footrest hinge 23 is in close contact with each side of the base 10 when the safety footrest 20 is folded to the surface of the base 10 as shown in FIG. 3, and for use When the safety footrest 20 is unfolded as shown in FIGS. 4 and 5, one wing is fixed to the rear bottom of the frame 21 so that the upper surface is parallel to the upper surface of the base 10. , It is preferable that the other wing is fixedly installed on the outer vertical surface exposed in the vertical direction from each bar of the upper frame 11 of the base 10.

In addition, the area of the frame 21 of the safety footrest 20 only needs to have an area sufficient for the worker to stand and work or walk around, so it has a rectangular frame shape with an area smaller than the total area of the upper frame 11. It may have, and the wire mesh 22 may include a so-called “tuning grill mesh” that is strong against load.

In addition, the plurality of handrails 30 include a general handrail that combines a plurality of vertical bars and horizontal bars in a grid form, and is connected to the other side of the safety footrests 20 through at least two handrail hinges 31 in FIGS. 4 and 4 As shown in Figure 5, it may be installed rotatably within a range of 90 degrees.

At this time, the inner portion of the handrail hinge 31 is in close contact with the upper surface of the safety footrest 20 when the handrail 30 is folded toward the safety footrest 20 as shown in FIGS. 3 and 3, and the hinge 31 for use is When unfolded from the safety step 20 as shown in FIG. 5, one wing is fixed to the upper surface of the safety step 20 so that the handrail 30 can be erected at a right angle outside the upper surface of the safety step 20. It is preferable that the other wing is fixedly installed on the bottom of the horizontal bar at the bottom of the handrail (30).

In addition, although not shown, a handrail fixture is further installed between the pillars or bottom horizontal bars on both sides of the handrail 30 and the upper surface of the safety footrest 20, so that the safety footrest 20 is installed as shown in FIG. It is spread parallel to the upper surface of the base 10, and the handrail 30 is erected vertically on the outside of the upper surface of the safety footrest 20 as shown in FIG. 5, and when a worker performs work, the handrail 30 is The safety footrest 20 may be maintained in a vertical position on the outer side of the upper surface.

In addition, at least one pair of the plurality of footrest supports 40 is provided in each safety footrest 20, and the upper ends are rotatably installed on the outside of the bottom of the safety footrests 20 through a support hinge 41. It can have a shape.

When using the motor disassembly workbench to which the present invention is applied, the step supports 40 like this are spread out so that the safety step 20 has the same surface as the upper surface of the base 10, and then the lower end contacts the ground. Just spread it out from the bottom of the footrest supporter 40 so that it can be used.

Therefore, since the scaffold supports 40 support the safety scaffolds 20 from the ground, when workers climb on the upper surface of the safety scaffolds 20 and perform inspection and disassembly work on a medium-sized motor, the scaffolding supports 20 do not move. It is maintained in a horizontal state with the upper surface of the base 10.

At this time, the footrest support 40 may be formed in multiple stages to enable height adjustment, and may also include additional fixtures, etc. installed at each stage.

Therefore, not only can the safety of workers be ensured, but the work space and movement lines of workers can be greatly expanded.

At this time, among the components of the auxiliary safety footrest 50, the foothold member 51 is adjacent to each other when the safety footholds 20 are unfolded from the base 10 using a relatively thick iron plate, etc. (20) It may have a shape corresponding to the shape of the space formed between them.

Here, the shape of the footrest member 51 may have a triangular shape, for example, but is not limited thereto and may have a fan-shaped or polygonal shape.

In addition, the pair of auxiliary handrail couplers 52 are installed on both corners of the upper surface of the footrest member 51, and a separate auxiliary handrail having a shape corresponding to the handrail 30 is attached to the footrest member ( It performs the function of allowing it to be detachably attached to the upper surface of 51).

In addition, the footrest member fixture 53 is installed to protrude downward from both corners of the bottom of the foothold member 51, and is installed on each side of the frame 21 of the safety footholds 20 adjacent to each other. It may be detachably coupled to the cylindrical auxiliary footrest coupler 24.

These footrest member fixtures 53 can detachably fix the auxiliary safety footrest 50 itself, that is, the foothold member 51, on the sides of the frame 21 of the safety footholds 20 adjacent to each other. It performs the function of allowing

In addition, the plurality of auxiliary handrails 60 have a shape similar to that of the above-mentioned handrail, and the lower ends of the pillars on both sides are removable from the auxiliary handrail coupler 52 installed on both sides of the upper surface of the footrest member 51. It has a combined form.

Therefore, the above-mentioned handrail 30 and the auxiliary handrail 60 are installed in succession on the outer upper surface of the safety step 20 and the auxiliary safety step 50 installed along the outer surface of the base 10. Therefore, the safety of workers working while moving along the safety step 20 and the auxiliary safety step 50 can be completely secured.

As described above, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention.
