The present invention relates to a workbench, and more particularly to a workbench used to work for the elevator installation in the elevator hoist.

In the recent elevator market, machineroom-less elevator systems have attracted much attention. Machine roomless elevators have many advantages, but there are many difficulties in installing elevator components that are placed on the top floor of the hoistway because there is no separate machine room. In particular, in recent years, when the building is high rise, special attention of the worker is required when installing the elevator component in a long vertical hoistway, and there is a high risk of safety accidents.

Scaffolding as shown in FIG. 5A has conventionally been used to install elevator system components, including elevator cars, in a hoistway.

As shown in the drawing, the provision of a work space using the scaffold 110 is achieved by gradually stacking a large number of parts from each other at the bottom of the hoistway. In recent years, when the building is high rise, it becomes an inefficient method. In addition, the worker has to move up and down on the scaffold to work, so there is a great risk of safety accidents such as falling accidents.

It can be achieved by providing a work bench including a second support that provides space.

A third object of the present invention is a structure having an access passage formed on a wall forming a vertical passage to communicate with the vertical passage, the support and one end of which is coupled to one end of the upper surface of the support and the other end thereof upwards. A method of installing a workbench having an extended footrest, the method comprising: a) positioning the footrest in an access passage adjacent to the vertical passage with the footrest facing the vertical passage; b) placing the support adjacent to one end of the support. Securing to the bottom of the access passage rotatably at a portion; c) coupling a horizontal support having a length greater than the width of the access passage to the other end of the support; d) allowing the horizontal support to contact the wall. Rotating the other end of the support about one end of the support until e) securing the transverse support to the wall, And f) securing the other end of the scaffold to the wall opposite the access passage.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

2A and 2B show front and side views of the workbench in a reduced volume for movement to an installation site for installation of the workbench.

The work table at the time of movement includes the support stand 2, the inner side support stand 1c, the foot support stand 1, the upper support stand 3, the wheel supporters 2b and 2h, and the carrying cover 27.

The support 2 has various shapes such as a frame shape having a rectangular frame having a substantially rectangular shape having a predetermined width and having a plate shape or a pair of horizontal members and a pair of vertical members respectively coupled to both ends of the horizontal members. Can be produced with On the upper surface of the support, when the workbench is installed, the safety bar connecting portion 2d to which the safety bars 17 and 18 (refer to FIG. 1) are protruded is formed.

An inner scaffold support 1c is coupled to one end of the upper surface of the support 2 and extends upward. The inner scaffold support 1c has a width of approximately the same size as the support 2, and the scaffold support 1 is rotatably coupled to the end by the hinge member 5. The footrest support 1 also has a width approximately the same size as the inner footrest support 1c. The rotatable range of the scaffold support 1 is rotated counterclockwise from the state where the scaffold support 1 forms a straight line with the inner scaffold support 1c and as shown in FIG. 2A, the safety bar connection portion of the support 2 is shown. It is about 90 degrees until it contacts 2d. The length of the inner footrest support 1c is configured to be approximately equal to the length of the safety bar connection 2d so that the footrest support 1 can be in parallel with the support 2 when the footrest support 1 is folded and placed on the safety bar connection 2d. It is desirable to have. The inner scaffold support 1c and the scaffold support 1 support the scaffold 13 (see FIG. 1) where the operator stands when the work bench is completely installed.

The upper support 3 is coupled to the other end of the upper surface of the support 2 to extend upward. The inclined support 3a may be coupled to support the coupling between the support 2 and the upper support 3. The upper support 3 is to support the upper footrest 21 (see Fig. 1) when the workbench is installed.

The wheel support 2h and the hinge wheel support 2b are coupled to the lower surface of the support 2. The hinge wheel support 2b is rotatably coupled to the support 2 with respect to the support 2 about the hinge 2a, and also rotatably supports the wheel 2f. One end of the fixing bracket 2c is coupled to the hinge wheel support 2b to prevent the hinge wheel support 2b from rotating about the hinge 2a and to fix and maintain the engagement angle therebetween when the worktable moves. do. The other end of the fixing bracket 2c is coupled to the support 2 by bolts 2g.

As can be seen in FIG. 2B, an anchor bracket 2e and a bracket support 2j are also coupled to the hinge wheel support 2b. The anchor bracket 2e is used when the hinge wheel support 2b is later fixed to the bottom of the access passage and includes a through hole 2k through which the anchor bolt penetrates, and is coupled to the bracket support 2j during movement. In a preferred embodiment the hinge wheel support 2b is provided only in one of two installation positions of the end of the support to which the footrest support 1 is coupled and the wheel support 2h in the other three places.

The carrying cover 27 is coupled to the cover receiving portion 1a protruding from the scaffold support 1 and surrounds three surfaces except for the portion having the upper support 3 among the four sides of the support 2. Is installed. The carrying cover 27 serves as a fence for accommodating more materials or parts in the workbench when moved, and is thus coupled to the scaffold support 1 only when the workbench is moved.

As described, the work bench is provided with wheels 2f and can be folded about the inner scaffold support 1c such that the scaffold support 1 is in a direction parallel to the support 2 so that the volume thereof can be greatly reduced. In addition, since the carrying cover 27 and the upper supporter 3 form a receiving space on the upper supporter 2, many working members such as other parts or tools forming the worktable can be loaded on the worktable.

Hereinafter, the process of installing the work bench which has been moved to the installation place will be described.

3A and 3B illustrate a preliminary assembly process performed before the work bench in the state shown in FIG. 2A is installed at the installation site.

Referring to FIG. 3A, first, the transport cover 27 is removed and then the scaffold support 1 is lifted to engage the pull-out support 7. Like the scaffold support 1, the withdrawal support 7 also functions to support the scaffold 13. At one end of the lead-out support 7, a fixing plate 7b in which an anchor bolt fastening through hole 7a is formed is formed. At the free end of the scaffold support 1, a receiving groove (not shown) for accommodating the other end of the pull-out support 7 is formed to have a constant length. In the receiving groove, the withdrawal support 7 is fitted with a so-called "telescopic coupling". Thus, the overall length of the pull-out support 7 and the scaffold support 1 in the engaged state is adjustable. In a preferred embodiment of the present invention, the take-out support 7 and the receiving groove receiving it have approximately the same cross-sectional shape, preferably a rectangular cross section. In addition, when the withdrawal support is a rectangle of approximately 40mm x 40mm, and the receiving groove of the scaffold support 1 is a rectangle of approximately 48mm x 48mm, the length of the portion where the two members overlap each other is preferably 20 cm or more.

After coupling the withdrawal support 7, the operation of fixing the footrest support 1 and the inner footrest support 1c in line with each other is fixed. As shown in FIG. 3C, the fixing operation of the aligned scaffold support 1 and the inner scaffold support 1c uses hollow members 1d and 1e respectively formed on the scaffold support 1 and the inner scaffold support 1c. It is done by The hollow members 1d and 1e are configured to be aligned with each other when the footrest support 1 and the inner footrest support 1c are aligned, and the stopper 1g is coupled to the hollow members 1d and 1e.

Next, referring to FIG. 3B, the inclined support 4 is coupled to the support 2 and the scaffold support 1 to more firmly support the combination of the two members. A coupler 2i is formed in the support 2 for engagement of the inclined support 4, and a coupler 1f is formed in the scaffold support 1.

As shown in FIG. 3D, after the inclined support 4 is coupled, the horizontal support 9 is coupled to the support 2. The function of the lateral support 9 will be described later with reference to FIG. 4B.

As shown in Figure 3e, in the preferred embodiment of the present invention by using the pre-assembled work bench as a unit work unit, a pair of unit work benches are combined with each other to form the entire work platform. That is, after positioning a pair of unit workbench so that each hinge wheel support 2b is located outside the assembly, the footrest supporter 1 and the footrest supporter 1 are bolted against each other, and the supporter 2 and the supporter are bolted together. Tighten with bolts. In this way, when the unit work platform is used in combination with each other, it is possible to configure a work platform having an appropriate width according to the size of the access passage 99 communicating with the hoistway 98 (see FIG. 4A), while moving in order to install the work platform. Small volume and weight unit work platform is convenient to move.

On the other hand, in the scaffold support 1 and the inner scaffold support 1c, a plurality of horizontal beams 1b are formed to have a more rigid configuration than the support 2.

Hereinafter, the installation process of the workbench will be described using an example of a workbench in which a pair of unit workbenches are combined.

Referring to FIG. 4A, the work table having been pre-assembled is moved in the direction indicated by the arrow A with the scaffold support 1 facing the hoistway 98. The two fixation points 29 to which the work bench is to be fixed are determined to position the pair of hinge wheel supports 2b to the fixed point 29.

Next, as shown in FIG. 2B, the anchor bracket 2e fixed to the bracket support 2j is separated from the bracket support 2j, so that the through hole 2k is downward, and the anchor bracket 2e is moved back to the bracket support. Bind to (2j). Next, an anchor bolt is fastened to the through hole 2k to fix the hinge wheel support 2b to the bottom of the access passage 99.

Next, as shown in FIG. 4B, the support 2 and the hinge wheel support 2b are hinged 2a by releasing the bolt 2g (see FIG. 2A) that fixes the fixing bracket 2c to the support 2. Make it rotate around.

Next, the lifeline support bracket 32 is fixed to the wall 100 above the access passage 99 and the clasp 34 is installed on the bracket 32. Next, prepare the rope 30 and tie the end thereof to the transverse beam 1b of the scaffold support 1 through the latch.

In this state, the support 2 is lifted and rotated about the hinge 2a. While the support 2 is rotated, the scaffold support 1 is placed across the hoistway 98. When the support 2 rotates about 45 degrees or more, the rotation speed is increased by the weight of the scaffold support 1, etc. . In order to keep the rotation speed of the support 2 constant, it is preferable to rotate the support 2 while maintaining the proper rotation speed by using the rope 30.

As shown in FIG. 4C, when the support 2 is erected almost vertically, the transverse support 9 comes into contact with the wall 100 forming the entry and exit 99 so that the work platform can no longer rotate. The horizontal support 9 which is fixed to the support 2 to have such a function has a length larger than the width of the access passage 99. The anchor bolt is fastened through the through holes 9a formed at both ends of the horizontal support 9 in contact with the wall 100 so that the horizontal support 9 is fixed to the wall 100.

As shown in the drawing, when a pair of unit work benches are combined to form an entire work bench, the space 2m inside one support 2 may be an entrance through which an operator enters and exits another support 2. In the horizontal beam (2l) may be further connected to form a ladder. Such a ladder can be conveniently used when the worker climbs on the upper scaffold 21 (see Fig. 1) to be described later. That is, it is possible to use the two supports 2 for different purposes.

Next, as shown in FIG. 4D, the free end of the withdrawal support 7 coupled to the scaffold support 1 is fixed to the wall 100 facing the access passage 99. This operation is usually performed at the end of the scaffold support 1 so that the lifeline support bracket 32 is connected to the lifeline 36 and the harness 38 connected to the lifeline 36 is worn by the worker. It is preferable to be. When the withdrawal support 7 is pulled out from the scaffold support 1 in the direction indicated by the arrow A, and closely adhered to the wall 100, it is held in a cantilever shape in the hoistway 98 by the fixing plate 7b having a large surface area. There is an effect that the movement of the withdrawal support 7 is somewhat reduced.

Next, the extension scaffold 11 is positioned on the pull-out support 7 in the direction of the arrow B, from which the operator fastens the anchor bolt to the wall 100 through the through hole 7a of the fixing plate 7b. Do the work.

Next, as shown in FIG. 4E, the vertical support 8 is disposed so that one end thereof is coupled to the fixing plate adjacent to the extraction support 7 and the other end thereof faces upward, and then the other end is anchored to the wall 100. Secure with bolts. The vertical support 8 is provided with a corresponding connection 8a at a height approximately corresponding to the safety bar connection 2d of the support 2, and the upper support 42 is provided at a height corresponding to the upper support 3. Formed. The second upper scaffold support 12 is coupled to the corresponding upper support 42.

Next, as shown in FIG. 4F, the first upper scaffold support 20 is coupled to the upper support 3. In addition, both ends of the footrest 13 are fixed to the support 2 and the vertical support 8 in a state where the footrest 13 is extended on the footrest support 1 and the inner footrest support 1c. Safety bars 17 and 18 are coupled to the safety bar connection part 2d and the corresponding connection part 8a, respectively.

Next, as shown in FIG. 4G, the third upper scaffold support 46 is coupled onto the first and second upper scaffold supports 20 and 12. Thereafter, a pair of first upper safety bar support pillars 22 are coupled to one end of the first upper footrest support 20 and the third upper footrest support 46 to extend upward, and the second upper footrest support is extended. A pair of second upper safety bar support pillars 23 is coupled to the other end of the 12 and the third upper footrest support 46 to extend upward. The pair of first upper safety bar support pillars 22 are spaced apart from each other by the same size as the width of the upper supporter 3, and the pair of second upper safety bar support pillars 23 correspond to the corresponding upper supporter 42. Are spaced apart from each other by the same size as.

The upper scaffold 21 is positioned above the third upper scaffold support 46, and both ends thereof are fixed to the first and second upper safety bar support pillars 22 and 23.

Between the four upper safety bar support pillars 22 and 23, an upper safety bar 25 and 26 is installed at an appropriate height.

The worktable installed in this manner is shown in FIG. 1.

In describing the workbench of the present invention, an elevator hoistway was described as an example, but the present invention is not limited thereto. In particular, in all structures in which a long passage in the vertical direction is formed and an access passage through the passage is formed, the work bench of the present invention can be used when performing a high altitude work in the passage.

The working table of the present invention can be configured to combine the scaffold support rotatably with the inner scaffold support to reduce the volume of the entire work table and also have wheels, and to load a large number of work members using a carrying cover. Operation such as moving to install the is very convenient.

In addition, since the worktable is configured to rotate, there is an excellent advantage that almost no risk in the first installation with a lot of risks.

In addition, the length of the scaffold can be changed so that the workbench is installed in both end forms rather than in the cantilever form, but it is not necessary to change the dimensions of the workbench under different installation environments.
