[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail fixing device and a guide rail fixing method using the device.

[0002]

2. Description of the Related Art In general, an elevator is provided with a guide rail on an inner wall of a hoistway in order to guide a car and a counterweight so as to be able to go up and down. In the work of attaching the guide rails, first, the uppermost guide rail is lifted from below in the hoistway by a winch disposed on the top floor of the building or the like. Next, the next-stage guide rail is fastened and connected to the lower end of the uppermost guide rail by a relay bracket and a bolt, and the guide rail is lifted by a winch. Then, the series of fastening and lifting operations are repeated to lift the required number of guide rails in the hoistway, and using the work scaffold assembled in the hoistway, the guide rails integrally connected to the predetermined height of the hoistway inner wall. Position and fix.

[0003] In the case of a guide rail fixing work of a steel structure, a plurality of separator beams and the like are present at predetermined intervals on the inner wall of the hoistway, and a building constructor welds and fixes a fastener plate on the upper surface of each step in advance. However, at that time, deformation such as displacement due to welding is likely to occur. next,
A fire protection coating application company sprays a fire protection coating on the statutory metal parts. At this time, it may be applied to a fastener plate which does not have to be applied due to the complexity of the operation.
After that, the guide rail fixing worker swept with a rag,
Remove and clean the fire protection coating on the fastener plate,
Then, an L-shaped bracket is temporarily tightened in such a manner that the position can be adjusted in the front-rear and left-right directions, and the guide rail is fastened by the bracket and the rail clip for temporary attachment.

[0004] A piano wire, which is a centering reference line suspended in the hoistway, is used as a fixed reference, and a worker moves a bracket or inserts a thin liner with a positioning jig such as a scale using a work platform. Then, work to position the guide rail. After this positioning work, the bracket and the fastener plate are fully tightened, and finally fixed by welding. Next, slag, spatter and the like generated by welding are cleaned, and the rust preventive is removed by heat at the welded portion.

A worker works on a scaffold while assembling a working scaffold, and removes the scaffold after completion. However, the worker moves up and down the scaffold every time the height of the work place changes. It is necessary to lift parts and work tools such as brackets with the person. For this reason, there is a problem that a great deal of labor and time is spent, and it is difficult to secure safety by unsafe scaffolding work at a high place, and the physical and mental fatigue of the worker is large. Also,
Since elevators for high floors are installed in parallel with two or three elevators, the hoistway is rectangularly sectioned. Each elevator is divided by a separator beam, and the work procedure is to complete one elevator to prevent accidental falling accidents due to simultaneous upper and lower work, then move on to the next elevator construction, attach sheets to the separator beam, and move up and down Two types of construction methods were adopted, such as isolating the roads and performing them in parallel, each of which had poor workability, and an improvement in operation was desired.

In order to automate such operations in the hoistway, a working device in the hoistway as disclosed in Japanese Patent Application Laid-Open No. 58-193876 has been proposed. This uses a large work platform frame that moves up and down along a total of four guide rails for the car and guide rails for the counterweight on the inner wall of the hoistway, which are necessary for positioning and fixing the guide rails. Various devices are assembled.

However, in the hoistway working apparatus, since a large working frame is used, the entire apparatus is large and heavy, and the steps of carrying in and installing the hoistway in the hoistway are very troublesome. In addition, for low-level elevators, the ratio of the setup time to the total work time is increased, and the effect of automatic labor saving is not improved, and there is a problem in practicality. Since the apparatus itself is a large device and occupies a large space in the entire hoistway, there is inconvenience that other operations in the hoistway cannot be performed freely.

Accordingly, the present applicant has already proposed a guide rail installation means (Japanese Patent Application No. 4-183658) as an "elevator guide rail centering and fixing device".
It is a device that can be moved up and down along one guide rail suspended in the hoistway. It has excellent transportability, and can be easily set up for loading and setting into the hoistway. Can be automated.

[0009]

However, in recent years, the number of hoistways that make the space between the elevator hoistways as small as possible has been increasing in relation to the effective use of the site area of the building site. For this reason, there is a demand for a reduction in space on the rear surface of the guide rail for performing the fastening welding, and there is a problem that even a manual operation is difficult to reach and the adjustment is difficult. In addition, the work load for fixing the guide rails to the separator beam, which is a common part of two parallel elevators, which has been a problem even in the conventional manual work, is applied. Positional deviation occurs, or the measurement point when the guide rail is fixed is one point of the piano wire suspended in the hoistway, so it is extremely shifted by the connecting plate of the guide rail such as the fastener plate at the mounting position . In order to adjust the positioning of the guide rail equivalent to manual operation, a large-diameter adjustment hole on the bracket side and a large washer are required to cover the adjustment hole, and the bolt diameter becomes large.

Further, if the number of bolts and washers is, for example, the height of the hoistway is 100 m, the maximum distance of the bracket fastening is 100 m and the maximum distance of the bracket is 4 m or less. = 50 are required. However, because of the connection between the building and the guide rail, the bracket fastening interval is not always constant. For example, 2.5 m, 3.6 m, etc., it is an unspecified length of 4 m or less, so usually 50 or more bolts and washers are required. It is.
If the bolts and washers are lost each time, the work would be inefficient if the machine was lowered, supplied, or raised and lowered.

[0011] Further, in the lifting and lowering transfer method in a state where the bolt and the washer are assembled, there is a problem that the occupation ratio for the work is increased. In addition, it is necessary to consider the problem of the small space behind the guide rail and the separator beam, and if the same structure is used for both the high floor and the low floor, the occupancy of the low floor on the hoistway is high, and it is difficult to simultaneously proceed with the construction. In addition, in lower-rise buildings, the loading route was narrow, and the utilization rate on the lower floors was low due to transportation labor. In addition, it was impossible to follow the overall work such as the processing accuracy of the fastener plate and its mounting state, the work for removing the fire protection coating, the work for welding fixation and the application of rust prevention.

In the case of a high-floor building, there is a type in which a high-floor-dedicated building passes through a low-floor floor in order to shorten the ascent / descent time.
In the case of this type, the entrance is not always provided at each floor of the hoistway, and the entrance may be provided only at intervals of the fifth floor and the tenth floor. For this reason, when the guide rail fixing device is inoperable due to an internal factor such as a power down due to an external factor due to steel frame welding work during the operation of the guide rail fixing device, etc. This has made it difficult to make contact with the equipment, resulting in lost work time, and measures and measures to reduce it have also been issues.

Therefore, the present invention solves the above problems,
It is an object of the present invention to provide a guide rail fixing device which is simplified and simplified in terms of a mechanism portion and a control portion of the guide rail fixing device, and a guide rail fixing method using this device. The present invention also provides a guide rail capable of performing various operations such as removal of a fire protection coating, welding work, and rust prevention coating work by changing a peripheral mechanism part without changing a main mechanism part of a conventional guide rail fixing device. It is intended to provide a fixing device. Furthermore, according to the present invention, not only the fixing work but also from loading to withdrawal, the entire work of fixing the guide rails can be shortened and the mounting accuracy can be improved irrespective of single row and parallel, and the work of the workers at high places can be reduced. An object of the present invention is to provide a guide rail fixing device and a fixing method capable of reducing a heavy load lifting operation.

The guide rail mechanism is hung by the guide rail fixing device and the guide wheel mechanism is rolled thereon, so that the guide rail fixing device is not affected by positional shifts such as twisting of the gripping block due to rigidity of the main body structure of the guide rail fixing device and the rail core with respect to the guide rail. The position of the extension reference line is accurately detected, and the rigidity of the guide rail fixing device does not require super-rigidity. In addition, since the elevation counter always rolls on the guide rail, the measured height is detected, and the mounting height position of the fastener plate and the bracket can be detected with high accuracy.

The bracket fastening mechanism has a bracket fastening mechanism for each of the left and right clips, and the left and right clips can be relaxed, lowered, and fastened by a small number of drives by performing the operation by combining the lifting drive mechanism. .
Since the fastener fastening mechanism is provided on the positioning mechanism and the fastener fastening position is arranged at a geometric position after the positioning of the bracket is completed, the fastener fastening mechanism rotates to guide the fastener bolt and washer to the fastener fastening position. The number of drive shafts of the fastener fastening mechanism can be reduced and simplified.

The component supply mechanism is provided on the fuselage frame and simply transports the fastener bolt and washer to the bracket fastening location, and sets the supply operation within the operating range of the positioning mechanism and the fastener fastening mechanism, thereby reducing the number of operating axes. In addition, the temporary mounting table supplies the fastener bolt and washer during the movement between each fastening, one set is fixed to the temporary mounting table, and the other set is gripped by the fastener fastening mechanism, so that the nut runner and the fastener fastening mechanism etc. The number can be reduced and simplified.

The lifting drive mechanism is of a type in which the lifting wire is wound around the lifting drive mechanism from the entrance by friction and discharged from the outlet, so that the lifting drive can be performed as long as the lifting wire exists.
In addition, unlike the winding type elevator, the winding space of the lifting wire is always constant, so that the lifting wire processing is simple.

Further, by suspending the control device that controls the operation of the guide rail fixing device at the lowest position so as not to interfere with the operation, the control device does not affect the fixing work.

The guide rail fixing method according to claim 2 is

Can also be planned.

The reference line position as a positioning reference is such that the counter rail having a short distance between the guide rails is set as the reference length, and the reference line position is determined at an intermediate position between the counter rail and the counter rail. On the side, guide rail positioning can be performed with a total of six reference lines, two of which are in service, and the time required for reference line setting work can be reduced. The guide rail fixing device measures the installation data of the manually positioned guide rail, assembles the fastener bolts and washers, raises and lowers it, grips and loosens the temporarily attached bracket by the bracket fastening mechanism, and descends to the fastener plate position. Fasten and fix. Then, the positioning mechanism engages with the fastener plate and positions the fastener plate by the guide portion of the positioning mechanism. Then, the assembled fastener bolt and washer are fastened to the fastener plate to complete the operation.

According to a third aspect of the present invention, there is provided a guide rail fixing device,
Raise and lower the bracket fastening mechanism to the temporary attachment position of the bracket, and while being guided by the clip by the clip guide,
The bolt socket is inserted into the clip bolt, grips the bracket, and stops with the clip stopper. The load generated by performing the air cylinder operation of the bracket fastening mechanism can be protected by the bearing, and a circular spring that assists automatic centering return by hanging down or rotating by the weight of the bolt socket is incorporated and tapered at the tip end This facilitates insertion into the clip bolt. And
The clip is pressed against the guide rail while always pressing the bent portion of the clip at the time of the fastening operation by the roller and the plunger, so that the positional deviation due to backlash can be prevented.

In the bracket fastening method according to a fourth aspect, the height of the bracket fastener and the vicinity of the guide rail are detected and stored by the vertical movement of the lifting / lowering drive mechanism in the bracket fastener detection provided in the positioning mechanism. By comparing the end of the bracket with the side near the guide rail based on the detection height, the inclination direction of the temporary attachment bracket can be recognized by one detector. Similarly, the fastener plate accurately detects and stores the fastener plate while repeating the bracket fastener detection forward and downward and ascending and forward, and also measures the inclination direction of the fastener plate as well as the bracket inclination direction and recognizes the inclination direction and the amount . Then, one bracket fastening mechanism is positioned at one clip bolt position by elevating and lowering and stopped, and the clip bolt is relaxed.
At this time, the position of the clip bolt is fixed, and the bracket separates from the back of the guide rail in one direction due to the jack effect of the screw of the clip bolt, creating a gap, and the elevation drive mechanism moves the bracket so that it is horizontal and stops. . The clip bolt is gripped and loosened by the bracket fastening mechanism on the opposite side of the bracket fastening mechanism, whereby the bracket is detached from the back of the guide rail. Next, the bracket is lowered by the lifting drive mechanism to the stored fastener plate position, the bracket comes into contact with the fastener plate upon detection of the seating of the bracket, and after stopping the lifting, one of the clips is fastened and the bracket in the opposite direction is engaged by the lowering operation of the lifting and lowering. When the seating detection is input, the clip is fastened and the bracket is fastened.

This makes it possible to accurately recognize the inclination direction and the amount of the temporary attachment bracket or the fastener plate without using a complicated measuring device, and to combine the lifting drive mechanism with the bracket fastening mechanism of the left and right air cylinders. Can be fastened to the fastener plate position. Then, the clip can always be brought into close contact with the guide rail by a spring structure that presses the guide rail at the time of mounting, so that the cause of the positional deviation between the guide rail and the clip can be eliminated.

The guide rail fixing device according to claim 5 is
The bearing and spring incorporated between the nut runner and the bolt socket return the bolt socket to a vertical position with respect to an external load, work to prevent the external load from being transmitted to the nut runner, and protect the nut runner. Then, the bolt and the washer can be attracted by disposing the magnet in the bolt socket, and when detaching, the fastener bolt and the washer are separated from the bolt socket by fastening the fastener plate which is the fastening destination, and the bolt and the washer are removed. Adsorption and desorption can be performed easily. Fastening of the fastener plate and the bracket after positioning, geometrically determine the position of the guide plate of the fastener plate and the positioning mechanism,
After the positioning, the bracket can be moved to the fastening position by rotating the bracket fastening mechanism. Thereby, the mechanism and control of the bracket fastening mechanism can be simplified.

In the elevator fixing method according to the sixth aspect, when the fastener plate is coated with rust prevention, the locator diameter of the guide portion of the positioning mechanism is reduced to facilitate insertion into the locator hole. The locator hole and the guide portion, which receive the reaction force of the operation of the mechanism, play in the locator hole and the guide portion, causing a positional shift. Therefore, the positioning mechanism is used to roughly position the guide part with play, and the bolts and washers are fastened to the screw holes of the fastener plate with the fastener fastening mechanism, with the brackets alternately contacting the fastener plate with a weak fastening force. I do. Then, when repositioning is performed by the positioning mechanism, the gap in the locator hole disappears without moving the bracket due to the frictional force at the time of temporary fixing even if it moves to the gap that is a play, and the guide part is positioned while contacting the locator hole The force of the mechanism is transmitted and positioning is completed accurately. Then, since the right and left fastener bolts of the fastener plate are fastened alternately while confirming that the positions do not shift, the guide rail can be accurately fixed in position. The adjustment range of the positioning mechanism can be adjusted in the inclination angle in the blade surface direction of the guide rail and the front, rear, left and right directions by the joint pin and the bracket with the bracket adjustment hole, and the adjustment range is covered with a washer that covers the bracket adjustment hole. Naturally, it can be adjusted by the guide rail fixing device, the tip of the bolt is tapered, and the centering function of the bolt socket makes it easier to bite into the screw hole even if the fastener plate is clogged with paint.

Further, by changing the positions of the fastening holes of the fastener plate and the adjustment holes of the bracket and the arms of the fastener fastening mechanism in accordance with the periphery of the guide rail, the fastening can be performed without being affected by the building. By arranging the adjustment hole position and the temporary placing table position on the rotation circumference of the fastener fastening mechanism, a nut runner stand incorporating a set of nut runners, air cylinders and the like can be used.

As a result, it is possible to reduce the size and weight of the equipment and to increase the work efficiency over manual work regardless of the state of the building.

Turn and insert the bolt socket into the bolt head. At this time, if the bolt is not fixed, it cannot be inserted into the bolt head. Therefore, the rotation is stopped so that the bolt does not rotate, and the bolt socket is inserted into the bolt head while rotating, and stops. Next, the bolt is magnetically attracted to the bolt socket by lifting.

Further, the arrangement interval of the bolts is narrowed so that the bolts overlap the bolts, and the depth of the screw holes is also changed accordingly to increase the mounting density of the bolts. Thus, the fastener bolt can be transported with a simple structure.

Then, a fastener bolt is mounted on the bolt component supply mechanism itself without installing a drive device, and a washer is mounted on the washer component supply mechanism with a simple drive mechanism. Assembling and fastening supply of the bolt and washer are performed by driving a positioning mechanism and a fastener fastening mechanism. This makes it possible to carry bolts and washers exclusively and without complicated equipment,
In addition, the supply of the fastener bolt and the washer is selectively performed according to the elevating process and the shape of the building, so that the area occupied by the hoistway can be reduced by a small and lightweight mechanism.

Is compared with the position data from the reference detection mechanism of the guide rail fixing device, and the verticality with respect to the reference line from the difference between the respective mounting positions is obtained.

Thus, the vertical mounting accuracy of the guide rail can be measured.

In the guide rail fixing method according to the eleventh aspect, the reference detecting mechanism keeps a predetermined distance while sandwiching the guide rail, and each moves along the guide rail to measure the position of the reference line. Since the lower reference detecting mechanism cannot move because there is no moving mechanism, the positioning mechanism guides the lower reference detecting mechanism so as to enter the mounting range of the lower reference detecting mechanism, and moves the positioning mechanism back and forth and right and left for positioning.

As a result, two positions within the mounting accuracy of the guide rail and within the vertical accuracy can be simultaneously performed.
