There is a type without a machine room. In any of these types, a car buffer for decelerating and stopping the elevator car in an abnormal state and a weight buffer for decelerating and stopping the balance weight in an abnormal state are provided in the pit.

  Patent Document 1 describes an elevator shock absorber base in which a guide rail and a weight shock absorber are fixed on a beam laid at the bottom of an elevator pit. In Patent Document 1, an oil pan is installed in a hole provided in the beam, and an oil tank for guiding oil descending along the guide rail to the oil pan is provided between the guide rail and the oil pan. It is characterized by that.

  In addition, as a conventional weight buffer stand, as described in Patent Document 1, only a weight buffer is mounted, a hoisting machine base that supports the hoisting machine, and a buffer base that supports the shock absorber. And the type that doubles as a hoisting machine stand. An upward load is applied to the weight buffer stand serving also as such a hoisting machine stand via a rope or a hoisting machine. This upward load is approximately equal to the load capacity of the elevator car. Therefore, even if the upward load is applied, the weight buffer stand has a shape with a high section modulus such as a square pipe so as not to yield. However, the square pipe has a problem that the material cost becomes high. In addition, if the shock absorber table is manufactured by bending a flat plate with a low material cost, the section modulus becomes low, and the weight shock absorber table yields due to the upward load applied through the rope or hoisting machine. There was a problem that it was not practical.

The weight buffer stand that also serves as the hoisting machine base is provided with the lowermost ends of the rails 8a and 8b, the hoisting machine base 4 to which the hoisting machine 5 is attached, and the weight buffer 12 are attached. The weight buffer stand, which also serves as a hoisting machine stand, is installed in the pit together with the car shock absorber, and is used to decelerate and stop by receiving the falling weight and the cage. However, these shock absorbers do not buffer the free fall of the weights and the car, and when the car is overspeeding, the car is first stopped by turning off the power of the motor. The emergency stop device works and decelerates / stops. Even when the emergency stop device does not stop completely, when the weight or cage descends into the pit, it receives the weight or cage to decelerate and stop. The role of the shock absorber.

  In the first embodiment, as an elevator to which the present invention is applied, a machine room in which the control panel 19 and the hoisting machine 5 are provided in the hoistway 20 without providing a machine room as shown in FIG. A rope-type elevator with no cable is assumed. In the elevator, as shown in FIG. 5, an elevator car 21 and a balance weight 22 are connected via a rope 11 in the hoistway 20, and the rope 11 includes an upper return wheel 23 and a lower return wheel. It is hung around a car 24, a sheave 25 and the like. The elevator car is driven by the hoisting machine 5 using the frictional force between the cars 23 to 25 and the rope 11 and moves up and down in the hoistway 20. 29 is a landing door provided at the landing on each floor. The counter weight 22 is guided on both sides by rails 8a and 8b (not shown in FIG. 5, see FIG. 1), and moves up and down in the hoistway 20 in conjunction with the raising and lowering of the car 21. Further, in the pit 26, there are provided a car shock absorber 27 and a weight shock absorber base 28 which also serves as the hoisting machine base of the present invention.

  As shown in FIGS. 1 and 2, the weight buffer stand 28 that also serves as the elevator hoisting machine base according to the first embodiment includes the bending plate 1, the reinforcing members 2 a and 2 b, the plate 3, and the hoisting machine. It comprises a base 4, anchor bolts 6, bolts 9, rail clips 10, and rail fixing plates 7. The hoisting machine 5, the rope 11, the rail 8a, the rail 8b, and the weight buffer 12 are installed on the hoistway floor surface (that is, the pit floor surface) with anchor bolts 6 and bolts 9 at the time of elevator installation. The weight buffer stand 28 that also serves as an elevator hoisting stand is attached after installation. Below, each said member which comprises the weight buffer stand which served also as the hoisting machine stand of the elevator which concerns on this Embodiment 1 is demonstrated.

  First, the bending plate 1 (first housing) is composed of a single substantially rectangular flat plate, and as shown in FIG. 2, the side shape is substantially U-shaped (or substantially U-shaped). It is bent so that it becomes. As shown in FIG. 3, the bending plate 1 includes an outer surface on both sides (hereinafter referred to as both outer surfaces 1a and 1b), a lower surface 1c, and a flange portion 1d extending from both outer surfaces 1a and 1b and protruding outward. Consists of Further, the bent plate 1 is arranged with a substantially U-shaped opening portion facing upward, and extends from the installation position of the hoisting machine base 4 to the installation position of the rail 8b as shown in FIG. Yes. A rail fixing plate 7 for fixing the rails 8a and 8b is fixed to the bending plate 1 by welding.

  Further, the reinforcing members 2a and 2b (second casing) are both formed of a single plate having a substantially rectangular shape, and as shown in FIG. 2, the side surfaces are bent so as to have a substantially L-shape. A pair of molded members. When the reinforcing members 2a and 2b face each other in line symmetry, one reinforcing member 2 is formed. The reinforcing member 2 has a substantially U shape that is slightly larger than the bent plate 1 and is substantially similar to the bent plate 1. The inner shape of the reinforcing member 2 is complementary to the outer shape of the bending plate 1. Therefore, the reinforcing member 2 is disposed with the substantially U-shaped opening portion facing upward. At the time of assembly, the bent plate 1 is fitted inside the reinforcing member 2, and as a result, the reinforcing member 2 is provided so as to overlap the outer side of the bent plate 1 and the bent plate 1 is reinforced by the reinforcing member 2. The inner surface of the reinforcing member 2 is in close contact with both outer surfaces 1 a and 1 b of the bending plate 1. Further, the lower ends of the reinforcing members 2a and 2b constituting the reinforcing member 2 are structured to be recessed from both sides below the lower surface 1c of the bending plate 1, respectively. Thus, the hoisting machine base 4, the lowermost ends of the rails 8a and 8b, and the weight buffer 12 are installed in the hollow portion of the bending plate 1 reinforced by the reinforcing members 2a and 2b. All are fixed by bolts 9. In addition, although the example which comprises the reinforcing members 2a and 2b from a pair of two flat plates has been described, the present invention is not limited to this case, and the reinforcing member 2 is formed from a single flat plate in the same manner as the bent plate 1. You may make it comprise.

  In FIG. 1, the reinforcing member 2 a is installed on the back side of the bending plate 1, and the reinforcing member 2 b is installed on the front side of the bending plate 1. Therefore, in FIG. 1, only the reinforcing member 2b is shown, and the reinforcing member 2a is hidden in the bending plate 1 and is not shown. The reinforcing members 2a and 2b are fastened to the bending plate 1 with bolts 9, and welding is not used. Further, the reinforcing members 2a and 2b are not necessarily required to have the same length as the bending plate 1, and may be overlapped only at a portion necessary for strength. Accordingly, the reinforcing members 2 a and 2 b have the same length as the bent plate 1 or a shorter length than the bent plate 1. In the example of FIG. 1, the reinforcing members 2a and 2b are shorter than the bending plate 1 and extend from the installation position of the hoisting machine base 4 to the installation position of the weight buffer 12, and extend to the vicinity of the rail 8b. Not. The reinforcing members 2a and 2b are fastened together with the bending plate 1 to the hoistway floor by means of anchor bolts 6 and fixed together.

  The plate 3 is provided on the lower surface of the bending plate 1 at a position below the position where the rail 8b is located. The plate 3 has holes for passing the anchor bolts 6. When the plate 3 is installed on the floor of the hoistway, the anchor bolts 6 are used for fastening. The plate 3 is provided on the lower surface 1c of the bending plate 1 where the reinforcing members 2a and 2b are not installed, and has the same thickness as the reinforcing members 2a and 2b. By making the plate 3 and the reinforcing members 2a and 2b have the same thickness, the plate 3 adjusts the height of the portion where the reinforcing members 2a and 2b are not provided. It can be installed horizontally without tilting. As a result, when a downward load is applied to the bending plate 1, the load is applied substantially evenly to the surface of the bending plate 1, so that it is possible to prevent a large load from being locally applied to the bending plate 1. it can.

  Reinforcing members 2a and 2b and plate 3 are all in firm contact with the hoistway floor without any gap and are in firm contact with lower surface 1c of bending plate 1 without any gap. Therefore, by installing the reinforcing members 2a and 2b and the plate 3, the space between the lower ends of the rails 8a and 8b and the weight buffer 12 and the hoistway floor is filled with the reinforcing members 2a and 2b and the plate 3. There is no space there. Thereby, the resistance to the upward load applied to the weight buffer stand 12 via the rope or the hoisting machine is obtained.

  The hoisting machine stand 4 is for fixing and supporting the hoisting machine 5. The hoisting machine 5 has a hole for passing the bolt 9, and the hoisting machine 5 and the hoisting machine base 4 are fastened by the bolt 9, and welding is not used. As shown in FIGS. 1 and 2, the hoisting machine base 4 has holes for passing bolts 9, and the hoisting machine base 4 has bolts on the bending plate 1 and the reinforcing members 2a and 2b. No. 9 is used and welding is not used.

  The rail fixing plate 7 is fixed to the bending plate 1 by welding. When installing the rails 8a and 8b, first, the bolts 9 and the rail clips 10 are temporarily tightened into the holes opened in the rail fixing plate 7, and the rails 8a and 8b are directly placed on the bending plate 1, and then the bolts are mounted. 9 and the rail clip 10 are finally tightened.

  A hole for passing the bolt 9 is opened in the weight buffer 12, and after the weight buffer 12 is placed directly on the bending plate 1, the weight buffer 12 and the bending plate 1 are fastened together with the bolt 9. No welding is used for the weight buffer 12.

  When a person or a load is placed on the elevator car 21, as shown in FIG. 1, an upward load (hereinafter referred to as an upward load A) is applied via the rope 11 and the hoisting machine 5. This upward load A is generally a value almost equal to the load capacity of the elevator. The upward load A varies depending on the size of the elevator car 21. The reinforcing members 2a and 2b in the present invention are attached for the purpose of preventing the weight buffer stand 28 which also serves as a hoisting machine stand from being bent by the upward load A.

  Therefore, according to the magnitude of the upward load A, it is possible to change only the structure of the reinforcing members 2a and 2b while keeping the size of the bending plate 1 as it is. For example, as shown in FIG. 3, when the upward load A applied through the rope 11 and the hoisting machine 5 is small and the upward load A can be withstood only by the bending plate 1, the reinforcing members 2a and 2b are eliminated. It is also possible. On the contrary, when the upward load A applied through the rope 11 and the hoisting machine 5 is large and the strength of the shape shown in FIGS. 1 and 2 is insufficient, the shape of the reinforcing members 2a and 2b is changed as shown in FIG. It is also possible to change the shape to be strong against bending. In the example of FIG. 4, the shape of bending of the flange portions of the reinforcing members 2a and 2b is different from that of FIG. That is, in FIG. 2, the flange portions of the reinforcing members 2 a and 2 b are flat, whereas in FIG. 4, the tip of the flange portion is bent downward, and the shape of the flange portion is L-shaped.

  Since upward load A is not generated between the weight buffer 12 and the rail 8b, the reinforcing members 2a and 2b do not need to be extended to the vicinity of the rail 8b, but remain at the length near the weight buffer 12. ing. Therefore, it leads to saving of material cost.

  On the other hand, since a downward load (hereinafter referred to as a downward load B) acts on the rail 8a, rail 8b, and weight buffer 12, the rail 8a, the rail 8b, and the weight buffer 12 are moved up and down. If there is a gap between the roadbed surface and the roadbed surface, the portion cannot withstand the downward load B, and the bending plate 1 is likely to be bent. Therefore, the weight shock absorber stand 28 that also serves as the hoisting machine stand according to the present embodiment has the rail 8a, the rail 8b, and the rail so that there is no gap between the weight shock absorber 12 and the hoistway floor. Since the bending plate 1 and the reinforcing members 2a and 2b are provided in close contact with the floor surface of the hoistway 8a, the rail 8b, the weight buffer 12, and the hoistway, the rail 8a, the rail 8b, and the weight buffer 12 The space between the hoistway floor and the hoistway floor is devised so as to be filled with only members, and the bending plate 1 is prevented from bending due to the downward load B.

  Further, the weight buffer stand 28 also serving as the hoisting machine stand is composed of the bending plate 1, the reinforcing members 2a and 2b, the plate 3, the hoisting machine stand 4, the bolt 9, the rail clip 10, and the rail fixing plate 7 as described above. In this form, carry in and install. However, since the reinforcing members 2a and 2b and the hoisting machine base 4 are bolted rather than welded, if a problem with weight or space occurs during carrying-in or installation, even if the bolt 9 is inconvenient, loosen the bolt 9. If it is, decomposition | disassembly can be performed easily. Also, assembly can be easily performed. This leads to improved work during loading and installation.

Hereinafter, the manufacturing and installation method of the weight buffer stand 28 which also serves as the hoisting machine stand in the present embodiment will be described.
First, the bending plate 1 is formed by forming a single flat plate into a substantially U shape.
Next, the pair of rail fixing plates 7 are fixed to the bending plate 1 by welding in accordance with the width of the rails 8a and 8b to be installed (that is, the width of the counterweight 22).
Further, the pair of flat plates are formed in a substantially L shape so as to have a complementary inner shape with respect to the outer shape of the bending plate 1 to form the reinforcing members 2a and 2b. When the reinforcing members 2a and 2b face each other in line symmetry, the U-shaped reinforcing member 2 having a complementary inner shape with respect to the outer shape of the bending plate 1 is formed.
Both the substantially U-shaped open portions of the bending plate 1 and the reinforcing members 2a and 2b are arranged facing upward, the reinforcing members 2a and 2b are overlapped on the outside of the bending plate 1 and fastened with bolts 9 and bent. An assembly composed of the plate 1 and the reinforcing members 2a and 2b is formed. In addition, the said assembly may be assembled before carrying in, and may be assembled on-site at the time of carrying in.
The assembly is fastened together with anchor bolts 6 on the hoistway floor. At the same time, the plate 3 and the bending plate 1 are fastened together with anchor bolts 6 and fixed to the hoistway floor.
The hoisting machine base 4 has a hole through which the bolt 9 is passed. After the hoisting machine base 4 is directly placed in the hollow portion of the bending plate 1, the bending plate 1 and the reinforcing members 2a and 2b are used. As shown in FIG. 2, the bolt 9 is used for fastening.
The rail fixing plate 7 has holes for passing the bolts 9. The bolt 9 and the rail clip 10 are temporarily tightened in the holes opened in the rail fixing plate 7, and the rails 8a and 8b are connected to the inside of the bending plate 1. After placing directly in the cavity, perform final tightening.
Further, the hoisting machine 5 has a hole for passing the bolt 9, and is fastened with the bolt 9 together with the hoisting machine base 4.
The shock absorber 12 has a hole for passing the bolt 9, and after being placed directly on the bending plate 1, the bolt 9 is fastened together.
Note that the order of assembly and the order of installation are not limited to this, and may be performed in an order that is easy to do before or during loading.
As described above, the weight buffer stand that also serves as the hoisting machine stand according to the present embodiment is configured to be fixed by the bolt 9 or the anchor bolt 6 except for the rail fixing plate 7, and welded. Since no disassembly and assembly are possible anytime and anywhere, it is possible to easily change the above-described assembly order and installation order.

  Thus, the weight buffer stand that also serves as the elevator hoisting machine base according to the first embodiment includes the lowermost ends of the rails 8a and 8b, the hoisting machine base 4 to which the hoisting machine 5 is attached, and the weight buffering. A shock absorber base that also serves as an elevator hoisting machine base to which a unit 12 is attached, a bent plate 1 (first housing) formed by forming a single flat plate into a substantially U-shape, and a bent plate 1 and a reinforcing member 2 having a complementary inner shape with respect to the outer shape of the bending plate 1, and a substantially U-shaped opening between the bending plate 1 and the reinforcing member 2, Both are arranged upward, and the reinforcement ratio 2 is provided so as to overlap the outer side of the bending plate 1. In the substantially U-shaped inner cavity of the bending plate 1, the lowermost ends of the rails 8 a and 8 b, the hoisting machine The base 4 and the weight buffer 12 are attached by bolt joining. In the weight buffer stand that also serves as the elevator hoisting machine base according to the first embodiment, at the time of elevator installation, the lower ends of the rails 8a and 8b to be installed on the site, the lower surface of the weight buffer 12, and the hoistway floor surface The bending plate 1, the reinforcing members 2a and 2b, and the plate 3 are filled so that there is no gap between them. Further, the reinforcing members 2a and 2b for the purpose of improving the strength do not necessarily have the same length as the bent plate 1, and are in contact with and overlapped with the outer surfaces 1a and 1b and the lower surface 1c of the bent plate 1, It can be overlaid only on the points necessary for strength. In this way, since reinforcement can be added only at a portion necessary for strength, the configuration can be changed as appropriate, and the material cost can be saved. In addition, the reinforcing members 2a and 2b are overlapped not only on the outer surfaces 1a and 1b of the bending plate 1 but also on the lower surface 1c of the bending plate 1 and are fastened together with the bending plate 1 by bolt joining. Since the reinforcing members 2a and 2b extend below the bending plate 1, the reinforcing members 2a and 2b are configured to prevent the peeling from the bending plate 1, and the reinforcing members 2a and 2b are peeled off due to aging and load. Is preventing. Furthermore, since there is no gap between the bending plate 1 and the hoistway floor surface as described above, the bending plate 1 and the reinforcing members 2a and 2b are overlapped and directly attached to the hoistway floor surface. It has a structure capable of maintaining sufficient strength against the downward load acting on the rails 8a and 8b and the downward load generated when the balance weight collides with the weight buffer 12. In addition, since the bent plate 1, the reinforcing members 2a and 2b, and the hoisting machine base 4 are assembled by bolt joining, disassembly and assembly can be easily performed only by loosening or fastening the bolts even during loading and installation. Even if it is inconvenient in the assembled state due to problems with weight and space during loading and installation, it can be easily disassembled if the bolt 9 is loosened. At the same time, it can be disassembled and assembled as appropriate, leading to improved work during loading and installation. As described above, the weight buffer stand that also serves as the hoisting machine stand according to the present embodiment maintains strength as the weight shock stand, and realizes reduction of material cost, improvement of carrying-in and installation work.
