Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a guide rail fixing device for a car or counterweight moving up and down in an elevator hoistway.

[Technical background of the invention and its problems]

As is well known, an elevator car and a counterweight are guided along guide rails by guide rollers or guide shoes to ascend and descend within a hoistway. The guide rail is vertically supported and fixed to the inner wall of the hoistway by a fixing device using metal fittings such as angle members. The guide rails are usually fixed at intervals of about 2 to 3 meters for each guide rail over the entire height of the hoistway. For this reason, the number of metal fittings for the fixing device ranges from several tens to several hundred pieces per elevator.

Conventionally, the metal fittings of the fixing device generally have a construction error of about ±20 mm, so the distance between the inner wall of the hoistway and the back of the guide rail is measured for each elevator and at all fixing locations, and the actual dimensions are calculated. They were manufactured individually based on the standards, delivered to the site, and installed. For this reason, we make different metal fittings one by one,
It takes a lot of time and effort to manufacture, the product cost is high, and the installation work on site is very troublesome.Furthermore, it is not easy to make fine adjustments and it is very troublesome to insert a liner, so the efficiency of the installation work is extremely low. Katta.

For this reason, recently Jikko No. 54-34352, Jikko No. 55
As proposed in No. 6794 or Japanese Patent Publication No. 55-28992, fixing devices using metal fittings that can be mass-produced and are adjustable on site have been used.

An example of this will be briefly explained with reference to FIGS. 8 and 9. A wall-side metal fitting 2 has a vertical piece 2a that is attached to the inner wall 1 of the hoistway and a horizontal piece 2b that extends to the guide rail 3 side at right angles thereto. and a rail-side metal fitting 4 having an engaging horizontal piece 4a that is engaged with the upper surface of the horizontal piece 2b of the wall-side metal fitting 2, and a rail-holding vertical piece 4b that is perpendicular to the engaging horizontal piece 4a. Engagement of horizontal piece 2b and rail side metal fitting 4 A pair of left and right connecting long holes 2c and 4c are formed in the horizontal piece 4a, respectively, and these are overlapped vertically and fastened with fasteners 5 such as bolts, spring washers, and nuts. are doing. In addition, a pair of left and right clip attachment holes 4d are formed in the rail holding vertical piece 4b of the rail side metal fitting 4, and the left and right clips 6 are attached to the holes 4d so as to hold the guide rail 3 under pressure by tightening the bolts 7. A pair of left and right elongated mounting holes 2d are formed in the vertical piece 2a of the side metal fitting 2, and the wall side metal fitting 2 is installed by fitting the anchor bolts 8 protruding from the inner wall 1 of the hoistway and tightening them with nuts 9. This is the configuration that will be used.

During on-site installation, the wall side fitting 2 is attached to the hoistway inner wall 1, and the rail holding vertical piece 4b of the rail side fitting 4, which has been temporarily tightened with the fastener 5, is positioned on the back side of the guide rail 3. Loosen the fastener 5 and attach the rail side metal fitting 4 to the wall side metal fitting 2.
slide through the long fastening holes 2c, 4c to adjust the distance H from the hoistway inner wall 1 to the back surface of the guide rail 3, and then tighten the fastener 5 to connect the rail side metal fitting 4 to the wall side metal fitting 2. conclude,
Furthermore, the joints between the two are welded and fixed.

By the way, in the case of the above-mentioned rail fixing device, it is convenient because it can be adjusted on-site, but as mentioned above, the number of metal fittings of the guide rail fixing device for one elevator is very large, and each one has to be bolted and nutted. It is quite troublesome to adjust and tighten the fastener 5 using the fastener 5, and there is a problem that the work efficiency is low and a lot of labor is required. In addition, in order to insert and fasten the fasteners 5 into the long connecting holes 2c and 4c,
The width to which the spring washer of the fastener 5 joins (generally 20
The horizontal pieces 2b and 4b of the wall-side fitting 2 and the rail-side fitting 4 must be lapped by a width of approximately It had the disadvantage of being short.
Furthermore, it is necessary to form long holes for connection in both the wall-side metal fitting 2 and the rail-side metal fitting, which has the drawback of increasing manufacturing costs.

[Purpose of invention]

This idea was devised in view of the above circumstances, and it eliminates the various drawbacks of the conventional method, is easy to manufacture, reduces costs, is extremely easy and convenient to install and adjust at the installation site, and can be installed from the inner wall of the hoistway. It is an object of the present invention to provide a highly practical elevator guide rail fixing device that allows a wide range of adjustment of the distance to the guide rail.
