Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
As shown in fig. 1(a) to 1(f), the elevator 40 is generally hoisted in six steps. In an initial state, as shown in fig. 1(a), the bottom beam 32 spans between the hoistway front wall 11 and the hoistway rear wall 12, both ends of the bottom beam 32 are respectively inserted into the hoistway front wall 11 and the hoistway rear wall 12, wherein the part inserted into the hoistway front wall 11 is just at the hoistway entrance 13 of the elevator 40, and the machine room frame body 31 is placed on the bottom beam 32.
When the machine room frame body 31 needs to be lifted to a certain target height, as shown in fig. 1(b), the machine room frame body 31 is firstly lifted to a position located at a certain distance above the target height by using the lifting device 20. Then, as shown in fig. 1(c) and 1(d), the bottom beam 32 is lifted to the target height by the hoisting device 20, and the bottom beam 32 is manually inserted into the hoistway front wall 11 and the hoistway rear wall 12, so that the bottom beam 32 is in the state shown in fig. 1(e), and the bottom beam 32 can bear the weight of the machine room rack body 31. On the basis, the machine room frame body 31 is lowered and placed on the bottom beam 32, as shown in fig. 1 (f).
Because the bottom beam 32 supports the machine room frame body 31, a part of the bottom beam is inserted into the hoistway wall, if the bottom beam 32 needs to be pulled upwards for a certain height, the bottom beam 32 needs to be withdrawn from the hoistway wall. And the bottom beam 32 can not support the machine room frame body 31 after exiting the shaft wall. Therefore, in the process of completing one hoisting, the machine room frame body 31 and the bottom beam 32 are respectively pulled upwards. The machine room frame body 31 needs to be lifted upwards by using the lifting device 20, so that the machine room frame body 31 can be lifted upwards after the bottom beam 32 exits the shaft wall without being supported by the bottom beam 32, and the process is complicated.
Based on this, the present application provides a machine room frame device 30, comprising a machine room frame body 31 and a bottom beam 32. Wherein the bottom beam 32 is movably arranged on the machine room frame body 31. As shown in fig. 3 and 4, the bottom beams 32 are in an expanded state and a stored state with respect to the machine room frame body 31. As shown in fig. 2(a) and 3, in the expanded state, the bottom beam 32 extends out of the machine room frame body 31 and is inserted into the hoistway front wall 11 and the hoistway rear wall 12, so that the machine room frame body 31 is stabilized in this position. As shown in fig. 2(b) and 4, in the stored state, the bottom beam 32 exits the hoistway front wall 11 and the hoistway rear wall 12 and can be lifted and lowered along with the machine room frame body 31.
When the machine room rack body 31 needs to be lifted to a certain target height, as shown in fig. 2(b), the bottom beam 32 is first switched to the storage state. Then, as shown in fig. 2(c), the machine room frame body 31 is lifted upwards by the hoisting device 20, and in the process, the bottom beam 32 synchronously rises along with the machine room frame body 31. After reaching the target height, as shown in fig. 2(d), the bottom beam 32 is switched to the expanded state, and the bottom beam 32 is partially inserted into the hoistway front wall 11 and the hoistway rear wall 12 to be able to support the machine room rack body 31 located in the hoistway 10, so that the machine room rack body 31 is stably located at the target height.
In the whole process, the bottom beam 32 does not need to be lifted separately, so that the operation steps are greatly reduced, and the operation convenience is improved. In some embodiments, the machine room frame body 31 includes an upper frame 311 and a bottom frame 312, the bottom frame 312 is disposed at the bottom of the upper frame 311, and the bottom beam 32 is movably disposed with the bottom frame 312.
The bottom beam 32 may be a complete steel frame structure. The bottom beam 32 can be movably arranged with the machine room frame body 31 in a rotating, sliding or other matching way. For example, in one embodiment, the bottom beam 32 includes a rod member, the length direction of the rod member is parallel to the cross section of the hoistway 10, the rod member is rotatably arranged relative to the machine room frame body 31, and the rotating axis is parallel to the depth direction of the hoistway 10. It will be appreciated that for this purpose the lever is rotated in a plane parallel to the cross-section of the hoistway 10, switching between the deployed and stowed conditions.
Alternatively, in other embodiments, as shown in fig. 3, 4 and 6, the bottom beam 32 includes two sub-beams 321, the two sub-beams 321 are arranged at intervals, and both the two sub-beams 321 are movably disposed on the machine room rack body 31. Specifically, in one embodiment, the sub-beam 321 is movably disposed on the bottom frame 312.
In the unfolded state, one of the sub-beams 321 is partially inserted into the hoistway front wall 11, and the other of the sub-beams 321 is partially inserted into the hoistway rear wall 12, so that the machine room rack body 31 can be stably placed in the hoistway 10 under the supporting action of the two sub-beams 321. In the stowed state both sub-beams 321 exit the hoistway wall.
By using the two sub-beams 321 for being inserted into the hoistway front wall 11 and the hoistway rear wall 12 respectively to support the machine room rack body 31, the single sub-beam 321 has light weight and small volume, and is more convenient to operate.
Further specifically, as shown in fig. 3 to 6, in one embodiment, two of the sub-beams 321 are arranged at intervals in the front-rear direction of the hoistway 10. The two sub-beams 321 are arranged in a sliding manner with the machine room frame body 31, and the sliding direction is parallel to the front-back direction of the hoistway 10. The sub-beam 321 is switched between the expanded state and the stored state by sliding with respect to the machine room rack body 31.
Specifically, when the sub-beams 321 are required to be unfolded and inserted into the wall of the hoistway 10, the two sub-beams 321 move away from each other, so that the two sub-beams 321 partially extend out of the front side and the rear side of the machine room rack body 31 respectively and are further inserted into the hoistway front wall 11 and the hoistway rear wall 12 respectively. When the machine room frame device 30 needs to be lifted, the two sub-beams 321 move towards each other, so that the two sub-beams 321 both retreat into the shaft 10, and the sub-beams 321 can ascend along with the machine room frame body 31.
Further, as shown in fig. 2(a) -2 (d), the machine room frame device 30 further includes a transmission 33. As shown in fig. 3, 4 and 6, the transmission device 33 is in transmission fit between two sub-beams 321 belonging to the same base beam 32, so that when one of the sub-beams 321 is switched between the expanded state and the stored state, the other sub-beam 321 is synchronously switched between the expanded state and the stored state.
As shown in fig. 2(c), after the bottom beam 32 rises to the target height along with the machine room frame body 31, the worker at the hall entrance 13 can operate one of the sub-beams 321 closer to the hall entrance 13 to switch the sub-beam 321 to the expanded state, and in the process, the other sub-beam 321 is expanded synchronously under the action of the transmission device 33. The worker only needs to operate one sub-beam 321, so that on one hand, the convenience of operation is improved, and on the other hand, the safety of operation is also improved.
The transmission device 33 acts between two sub-beams 321 which are both arranged in a sliding manner relative to the machine room frame body 31, and when a worker applies a force to one of the sub-beams 321 to enable the sub-beam to slide relative to the machine room frame body 31, the other sub-beam 321 can synchronously slide relative to the machine room frame body 31 under the action of the transmission device 33.
Specifically, as shown in fig. 3 to 6, the transmission device 33 includes two first rollers 331 and a flexible member 332. The two first rollers 331 are both directly or indirectly rotatably connected with the machine room frame body 31. The two first rollers 331 are spaced apart from each other, and the flexible member 332 is wound between the two first rollers 331. The flexible member 332 includes two connecting sections 3321 located between the two first rollers 331, and the two sub-beams 321 are respectively connected to the two connecting sections 3321.
When the worker pulls or pushes one of the sub-beams 321 along the connecting section 3321, the flexible member 332 rotates. As the flexure 332 rotates, the sub-beam 321 connected to the other connecting segment 3321 follows a synchronous motion. In particular, the two sub-beams 321 move towards or away from each other.
The flexible member 332 may be a rope, a timing belt, a chain or rack, etc. Correspondingly, when the flexible member 332 is the chain, the first roller 331 is a sprocket. When the flexible member 332 is the rack, the first roller 331 is a gear.
Further specifically, in some embodiments, two first rollers 331 are arranged at intervals in the front-rear direction of the hoistway 10, and the axial direction of the first rollers 331 is perpendicular to the direction in which the two first rollers 331 are arranged at intervals.
The spacing direction of the two first rollers 331 is the same as the slidable direction of the sub-beam 321 relative to the machine room rack body 31. When the worker pulls or pushes one of the sub-beams 321 to move in the front-rear direction of the hoistway 10, the flexible member 332 rotates about the two first rollers 331 so that the sub-beam 321 connected to the other connection section 3321 moves in synchronization.
Further, as shown in fig. 6, in some embodiments, the machine room frame device 30 includes two bottom beams 32 and two transmission devices 33, the two bottom beams 32 are arranged at intervals, and the transmission devices 33 are disposed in one-to-one correspondence with the bottom beams 32.
In summary, as shown in fig. 6, the machine room shelf device 30 includes four sub-beams 321, and the machine room shelf body 31 can be supported at a target height by the four sub-beams 321.
The two bottom beams 32 are arranged at a spacing in the left-right direction of the hoistway 10. The four sub-beams 321 are distributed at four corners of a rectangle. The transmission 33 acts between two sub-beams 321 belonging to a base beam 32.
Further, as shown in fig. 5 to 7, the transmission 33 is located on a side of the corresponding base beam 32 adjacent to the other base beam 32. In particular, the flexure 332 is located on a side of the corresponding bottom beam 32 that is adjacent to the other bottom beam 32. The sub-beams 321 are connected with the corresponding connecting sections 3321 through intermediate transition pieces 34.
Still further, in a further embodiment, the bottom beam 32 is slidably disposed with the machine room frame body 31, such that the bottom beam 32 has the expanded state and the stored state with respect to the machine room frame body 31, and the sliding direction intersects with a hoistway wall.
As shown in fig. 3 to 6, the bottom beam 32 slides relative to the machine room frame body 31 in a direction perpendicular to the hoistway wall.
In some embodiments, as shown in fig. 3 to 6, the machine room rack body 31 is provided with a limit guide assembly 35, and the bottom beam 32 is slidably assembled to the limit guide assembly 35, so that the bottom beam 32 is slidably arranged relative to the machine room rack body 31. In other words, the bottom beam 32 is slidably disposed relative to the machine room frame body 31 through the limiting guide assembly 35.
Specifically, in an embodiment, as shown in fig. 3 to 6, the sub-beam 321 is slidably assembled to the position-limiting guide assembly 35, so that the sub-beam 321 is slidably disposed relative to the machine room rack body 31.
As shown in fig. 6, the machine room frame device 30 includes four limit guide assemblies 35, and one of the sub-beams 321 corresponds to one of the limit guide assemblies 35.
Further, in one embodiment, as shown in fig. 7 and 10, the bottom beam 32 is an H-shaped steel, and the length direction of the H-shaped steel is consistent with the slidable direction of the H-shaped steel relative to the machine room frame body 31.
As shown in fig. 5, 6 and 10, the position-limiting guide assembly 35 includes two position-limiting assemblies 351 respectively clamped on both sides of the web 3211 of the H-beam. The H-shaped steel can only slide back and forth in the length direction of the web 3211 under the clamping action of the two limiting assemblies 351.
In some embodiments, the bottom beam 32 includes two spaced H-sections, one of the H-sections being the sub-beam 321. The web 3211 of one of the sub-beams 321 has a limiting component 351 clamped on both sides.
As shown in fig. 8 to 10, each of the limiting members 351 includes a limiting main body 3511, a side roller 3512 and a supporting roller 3513, and the limiting main body 3511 is connected to the machine room rack body 31. Specifically, in one embodiment, the position-limiting body 3511 is connected to the bottom frame 312. Each H-beam corresponds to one of the limiting guide assemblies 35, one of the limiting guide assemblies 35 includes two limiting assemblies 351, and two limiting body members 3511 are respectively located at two sides of the web 3211 of the H-beam. The side roller 3512 and the support roller 3513 are both rotatably disposed on the corresponding main stopper 3511, and the outer peripheral surface of the side roller 3512 abuts against the side surface of the web 3211 facing the main stopper 3511, and the outer peripheral surface of the support roller 3513 abuts against the side surface of the wing 3212 of the H-beam.
The web 3211 of the H-beam can only slide along the longitudinal direction of the web 3211 by the clamping action of the side rollers 3512, the support roller 3513 also guides the H-beam, and the support roller 3513 can support the H-beam by abutting against the wing plates 3212.
The rotation axis of the side roller 3512 is parallel to the side surface of the web 3211 abutted by the side roller 3512, and is perpendicular to the longitudinal direction of the H-shaped steel. The rotation axis of the support roller 3513 is parallel to the surface of the wing plate 3212 abutted by the support roller 3513, and is perpendicular to the longitudinal direction of the H-beam.
As shown in fig. 8 and 9, each of the limiting assemblies 351 includes two side rollers 3512 and two support rollers 3513 rotatably disposed on the corresponding limiting body.
Further, as shown in fig. 3 and 4, in one embodiment, the machine room frame device 30 further includes a locking device 36, the locking device 36 has a locking state and an unlocking state, and the locking device 36 directly or indirectly acts between the bottom beam 32 and the machine room frame body 31;
when the locking device 36 is in the locking state, the relative position between the bottom beam 32 and the machine room frame body 31 is fixed;
when the locking device 36 is in the unlocked state, the bottom beam 32 can be switched between the expanded state and the stored state relative to the machine room frame body 31.
When the state of the bottom beam 32 does not need to be switched, the locking device 36 is in a locking state, so that the relative position between the bottom beam 32 and the machine room frame body 31 is fixed. When the state of the bottom beam 32 needs to be switched, the locking device 36 is switched to the unlocking state.
