Description

Technical Field

[0001] This application relates to the technical field of hoists for building construction, and in particular to a machine room assembly for a shaft hoist. Background Technology

[0002] A hoist is a type of vertical transportation equipment widely used in construction, mainly for the vertical transport of personnel and materials. One of its core components is the machine room assembly installed at the top of the hoist, which is responsible for driving the hoist's lifting and lowering actions.

[0003] A hoistway uses traction ropes to pull the car, and the car's movement is achieved through the balance of counterweights. Existing hoistway machine rooms typically employ a fixed structure. The machine room assembly usually includes a main unit and a supporting structure. The main unit is the power unit that drives the car and controls the release length of the traction ropes. The supporting structure guides and secures the tail end of the traction ropes. The main unit and supporting structure are positioned opposite each other on the inner walls of the hoistway. A load-bearing beam is detachably installed inside the hoistway to support the machine room assembly. After completing construction on a certain floor, the following steps must be followed: First, lift the machine room assembly a certain distance to release the load-bearing beams from their stress state; then, remove the load-bearing beams from the hoistway; finally, hoist the machine room assembly to the corresponding height, and then reinstall the load-bearing beams in their corresponding positions to support the machine room assembly.

[0004] The most common form of a hoistway is rectangular or square. The load-bearing beams are usually set horizontally along the long or short side of the hoistway, cooperating with the structure of the inner wall of the hoistway to form a stable load-bearing frame. The machine room assembly is also set along the long or short side of the hoistway. When dealing with buildings of special shapes or transporting oversized or irregularly shaped items, it is necessary to adjust the exit position of the car. The angle adjustment of the car is achieved by adjusting the angle of the machine room assembly. Since the machine room assembly is large in size, there may still be a certain degree of angular deviation after adjusting the angle of the machine room assembly. The machine room assembly can only be lifted up again for angle adjustment, which is time-consuming and labor-intensive, limiting the versatility and flexibility of the machine room assembly.

[0005] Therefore, a new type of machine room assembly for hoisting machines is needed to solve the problem that existing machine room assemblies cannot be finely adjusted in angle according to actual conditions after position adjustment, and the position of the machine room assembly can be flexibly adjusted according to needs, thereby improving the utilization of resources. Summary of the Invention

[0006] In order to enable the machine room assembly to be rotatably mounted on the load-bearing beam and to facilitate fine-tuning of the angle of the machine room assembly, this application provides a machine room assembly for a hoist.

[0007] This application provides a machine room assembly for a hoist, which adopts the following technical solution:

[0008] A hoist room assembly includes a main body comprising a main structure and an opposing structure, which are disposed opposite to each other on the inner wall of the hoistway. The main body also includes a mounting beam supporting the main structure and the opposing structure, which are fixedly mounted at both ends of the mounting beam. A bottom frame is rotatably mounted on the bottom end of the mounting beam, and a channel for a load-bearing beam to pass through is provided on the bottom frame. The main body is mounted on the load-bearing beam via the bottom frame.

[0009] By adopting the above technical solution, the computer room assembly can support the host structure and the supporting structure through the mounting beam. The bottom frame is rotatably connected to the bottom end of the mounting beam. The computer room assembly is erected on the load-bearing beam in the shaft through the channel on the bottom frame. Compared with the existing technology, when making fine adjustments to the angle of the computer room assembly, the mounting beam is rotated around the bottom frame, and there is no need to re-hoist the computer room assembly, which enhances the installation flexibility and adaptability of the computer room assembly.

[0010] Optionally, the mounting beam includes a main longitudinal beam and a telescopic beam for adjusting the distance between the main structure and the opposing structure. The main structure is fixedly mounted on the main longitudinal beam, and the opposing structure is fixedly mounted on the telescopic beam. The main longitudinal beam and the telescopic beam are equipped with locking components, and the telescopic beam is slidably mounted on the main longitudinal beam and locked and fixed by the locking components.

[0011] By adopting the above technical solution, the distance between the host structure and the opposite structure can be adjusted through the sliding cooperation between the telescopic beam and the host longitudinal beam, which can adapt to different installation requirements. After the telescopic beam slides on the host longitudinal beam, it is locked and fixed by the locking component to ensure the structural stability of the computer room overall structure after adjustment, so that the computer room overall structure can maintain stable operation.

[0012] Optionally, multiple main longitudinal beams and telescopic beams are provided, and their positions correspond one-to-one. The mounting beam also includes a main crossbeam and a supporting crossbeam. The main crossbeam is fixedly installed on one end of the multiple main longitudinal beams away from the telescopic beam, and the supporting crossbeam is fixedly installed on one end of the multiple telescopic beams away from the main longitudinal beam.

[0013] By adopting the above technical solution, the main longitudinal beam is installed at the end of the main crossbeam, and the telescopic beam is installed at the end of the opposite crossbeam. Multiple main longitudinal beams and telescopic beams are provided and are arranged in a one-to-one correspondence, which enhances the overall structural strength and stability of the mounting beams and helps to more stably support the main structure and the opposite structure.

[0014] Optionally, a first mounting plate with a protrusion is fixedly installed at the end of the main beam, and the first mounting plate is provided with a first locking member that is threaded with the inner wall of the shaft. A second mounting plate is fixedly installed at the end of the opposite beam, and the second mounting plate is provided with a second locking member that is threaded with the inner wall of the shaft.

[0015] By adopting the above technical solution, the first mounting plate is located at the end of the main beam and is threaded to the inner wall of the shaft through the first locking member. The second mounting plate is located at the end of the opposite beam and is threaded to the inner wall of the shaft through the second locking member. Through the first locking member on the first mounting plate and the second locking member on the second mounting plate, the main body of the computer room can be firmly installed on the inner wall of the shaft, thereby improving the stability and firmness of the installation of the main body of the computer room.

[0016] Optionally, the channel includes a lateral opening and a longitudinal opening, which are located on two adjacent sides of the bottom frame.

[0017] By adopting the above technical solution, the main structure of the computer room can cooperate with the load-bearing beam through the horizontal and vertical openings of the bottom frame. The load-bearing beam can be installed through the horizontal or vertical opening as needed, making it easier to install the main structure of the computer room on the load-bearing beam and improving the adaptability and installation convenience of the main structure of the computer room.

[0018] Optionally, the main unit longitudinal beam is fixedly installed with a rope head clamping structure for fixing the traction rope head. The rope head clamping structure includes a transverse clamping component that clamps the traction rope upward along the axial direction of the main unit longitudinal beam and a vertical clamping component that clamps the traction rope along the lifting direction of the main unit.

[0019] By adopting the above technical solution, the lateral clamping component clamps the traction rope along the longitudinal beam of the main unit, and the vertical clamping component clamps the traction rope along the lifting direction of the main unit of the machine room, which can effectively fix the rope head and ensure the stability of the traction rope connection.

[0020] Optionally, the lateral clamping assembly includes a detachably fixed first lateral clamping plate and a second lateral clamping plate. The first lateral clamping plate has a first clamping groove, and the second lateral clamping plate has a second clamping groove that is opposite to the position of the first clamping groove. The first lateral clamping plate and the second lateral clamping plate are brought close to each other so that the first clamping groove and the second clamping groove together clamp the traction rope.

[0021] By adopting the above technical solution, the first and second transverse clamping plates of the transverse clamping assembly clamp the traction rope together through the first and second clamping grooves, thereby achieving effective clamping and fixing of the traction rope in the axial direction of the main machine longitudinal beam.

[0022] Optionally, the rope head clamp structure further includes a pressing component for reinforcing and fixing the traction rope. The pressing component includes a clamping member for pressing and fixing the traction rope and a guide rod for guiding the clamping member to press down. The guide rod is fixedly installed on the longitudinal beam of the main unit and slides in cooperation with the clamping member.

[0023] By adopting the above technical solution, the clamping component moves downward along the guide rod and presses down to fix the traction rope, thereby strengthening the fixing effect on the traction rope and further enhancing the stability of the overall structure of the computer room.

[0024] Optionally, the main longitudinal beam is also fixedly installed with a pressure plate assembly for keeping the traction rope vertical. The pressure plate assembly includes a first pressure plate and a second pressure plate that can be detachably fixed. The first pressure plate has a first pressure groove, and the second pressure plate has a second pressure groove that is opposite to the position of the first pressure groove. The first pressure plate and the second pressure plate are close to each other so that the first pressure groove and the second pressure groove together clamp the traction rope.

[0025] By adopting the above technical solution, the first and second pressure plates are brought close to each other so that the first and second clamping grooves clamp the traction rope together, which can limit the traction rope to remain vertical. During the lifting and lowering of the machine room assembly, the car and counterweight can be kept from swinging, thereby reducing the degree of swing of the car and counterweight.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up mounting beams to support the host structure and the supporting structure, and placing the entire computer room unit on the load-bearing beams through the bottom frame, the angle of the computer room unit can be finely adjusted by rotating the mounting beams, thus improving the versatility and flexibility of the entire computer room unit.

[0028] 2. The mounting beam is equipped with a telescopic beam and a locking assembly. The telescopic beam and the locking assembly can slide relative to each other, and the distance between the main structure and the opposite seat structure can be adjusted to meet the needs of different sizes of hoistways and cars, thus improving flexibility.

[0029] 3. The rope head clamp structure and pressure plate assembly can fix and limit the traction rope, ensuring the stability of the traction rope and facilitating the stable operation of the elevator. Attached Figure Description

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0044] Example:

[0045] A machine room assembly for a hoist, reference Figure 1 and Figure 2 The system includes a main unit 1 for the computer room, which comprises a main unit structure 111, a supporting structure 121, and a mounting beam 2. The main unit structure 111 and the supporting structure 121 are fixed to both ends of the mounting beam 2. The mounting beam 2 is installed on the inner wall of the shaft and supports the main unit structure 111 and the supporting structure 121. A bottom frame 3 is provided on the mounting beam 2, and the bottom frame 3 is rotatably mounted on the bottom end of the mounting beam 2 via bearings. A channel 311 is provided on the bottom frame 3. Figure 11The dimensions of the passage 311 are slightly larger than the cross-section of the load-bearing beam 9. The load-bearing beam 9 passes through the passage 311, allowing the mounting beam 2 to be erected on the load-bearing beam 9. When it is necessary to fine-tune the installation direction of the main unit 1 of the computer room, the mounting beam 2 is directly rotated. The mounting beam 2 rotates around the bottom frame 3 to the target angle. By rotating, the spatial orientation of the main unit structure 111 and the opposite seat structure 121 is changed, so as to flexibly adjust the exit direction of the car 131. During the rotation, the load-bearing beam 9 always passes through the passage 311 on the bottom frame 3, providing support for the main unit structure 111 and the opposite seat structure 121.

[0046] refer to Figure 1 and Figure 3 The mounting beam 2 includes a main longitudinal beam 211 and a telescopic beam 221. The telescopic beam 221 is slidably mounted on the main longitudinal beam 211. The main structure 111 is fixedly mounted on the main longitudinal beam 211, and the opposing structure 121 is fixedly mounted on the telescopic beam 221, thereby adjusting the distance between the main structure 111 and the opposing structure 121. The upper and lower ends of the main longitudinal beam 211 are folded inward to form a transverse folded portion 212. The edge of the transverse folded portion 212 is folded vertically to form a vertical folded portion 213. Under the limitation of the transverse folded portion 212 and the vertical folded portion 213, the sliding process of the telescopic beam 221 on the main longitudinal beam 211 is more stable, thereby enhancing the structural stability of the telescopic beam 221 and the main longitudinal beam 211.

[0047] refer to Figure 1 and Figure 3 The main longitudinal beam 211 and the telescopic beam 221 are equipped with locking components 4. The telescopic beam 221 is slidably mounted on the main longitudinal beam 211 and locked and fixed by the locking components 4. The locking components 4 include a first bolt 411 and a first threaded hole 412. The first bolt 411 is detachably mounted on the main longitudinal beam 211, and the first threaded hole 412 is located on the telescopic beam 221. The first bolt 411 passes through the main longitudinal beam 211 and is threadedly locked with the first threaded hole 412, thereby locking and fixing the main longitudinal beam 211 and the telescopic beam 221. When it is necessary to adjust the distance between the main structure 111 and the opposite structure 121, the first bolt 411 is disengaged from the first threaded hole 412 and the telescopic beam 221 is allowed to slide freely. After the distance is adjusted to the target position, the first bolt 411 and the first threaded hole 412 are re-locked.

[0048] refer to Figure 4 and Figure 5Multiple mainframe longitudinal beams 211 and telescopic beams 221 are provided. Each telescopic beam 221 is slidably installed on the corresponding mainframe longitudinal beam 211. The mounting beam 2 also includes a mainframe crossbeam 231 and a supporting crossbeam 241. The mainframe crossbeam 231 is fixedly installed on one end of the multiple mainframe longitudinal beams 211 away from the telescopic beams 221, thereby fixing the position of the multiple mainframe longitudinal beams 211 in the lateral direction. The supporting crossbeam 241 is fixedly installed on one end of the multiple telescopic beams 221 away from the mainframe longitudinal beams 211, thereby fixing the position of the multiple supporting crossbeams 241 in the lateral direction. This makes the computer room overall structure 1 form a stable frame structure, thereby improving the overall structural stability.

[0049] refer to Figure 4 and Figure 5 A first mounting plate 2311 is fixedly installed at the end of the main beam 231. A first locking member 2312 is detachably installed on the first mounting plate 2311. The first mounting plate 2311 is fixed to the end of the main beam 231 by welding and protrudes from the edge of the main beam 231. It is threadedly connected to the inner wall of the shaft by the first locking member 2312, thereby fixing the main beam 231 to the inner wall of the shaft. A second mounting plate 2411 is fixedly installed at the end of the counterbeam 241. A second locking member 2412 is detachably installed on the plate 2411. The second mounting plate 2411 is L-shaped and includes a fixed end 2413 and a connecting end 2414. The fixed end 2413 of the second mounting plate 2411 is fixed to the opposite crossbeam 241 by bolts. The connecting end 2414 of the second mounting plate 2411 is threadedly connected to the inner wall of the shaft on the other side by the second locking member 2412. It cooperates with the first mounting plate 2311 to lock the position of the main body of the machine room 1 on the inner wall of the shaft.

[0050] refer to Figure 1 and Figure 4 The channel 311 on the bottom frame 3 includes a transverse opening 312 and a longitudinal opening 313. The transverse opening 312 is located on the side of the bottom frame 3 and extends along the length of the main beam 231. The longitudinal opening 313 is located on another adjacent side of the bottom frame 3 and extends along the length of the mounting beam 2. The transverse opening 312 is smaller than the longitudinal opening 313. Figure 11 The load-bearing beam 9 can be passed through the channel 311 from different directions. The bidirectional opening design of the channel 311 allows the bottom frame 3 to be rotated to switch the adaptation direction without disassembly, thereby quickly adjusting the installation angle of the computer room main body 1.

[0051] refer to Figure 1 and Figure 6 The main unit's longitudinal beam 211 is fixedly mounted with a mounting bracket 251 and a rope end clamp structure 5. The rope end clamp structure 5 is fixedly mounted on the mounting bracket 251, and then combined with... Figure 2After the traction rope is released from the reel 8, it enters the rope head clamp structure 5. The mounting frame 251 is fixed to the main machine longitudinal beam 211 by bolts, which facilitates the overall installation and disassembly of the rope head clamp structure 5. After the initial end of the traction rope is guided and fixed by the rope head clamp structure 5, it lifts the car 131. The rope head clamp structure 5 includes a transverse clamping assembly 511, which includes a first transverse clamping plate 512 and a second transverse clamping plate 513. The first transverse clamping plate 512 and the second transverse clamping plate 513 are horizontally arranged on the mounting frame 251, and the first transverse clamping plate 512 is fixedly installed on the mounting frame 251. On the mounting frame 251, the second transverse clamping plate 513 is fixed to the first transverse clamping plate 512 by bolts. The first transverse clamping plate 512 has a first clamping groove 5121 on the side facing the second transverse clamping plate 513, and the second transverse clamping plate 513 has a second clamping groove 5131 on the side facing the first transverse clamping plate 512. The first clamping groove 5121 and the second clamping groove 5131 are positioned opposite each other. The first transverse clamping plate 512 and the second transverse clamping plate 513 are locked and fixed, so that the first clamping groove 5121 and the second clamping groove 5131 cooperate to clamp the traction rope and prevent the traction rope from deviating.

[0052] refer to Figure 6 and Figure 7 The rope end clamping structure 5 also includes a pressing component 531. The traction rope extends from one end of the transverse clamping component 511 and enters the pressing component 531 to strengthen the fixation of the traction rope. The pressing component 531 includes a clamping member 532 and a guide rod 533. Two guide rods 533 are provided and symmetrically fixed on the mounting bracket 251. The clamping member 532 slides with the guide rod 533. When it is necessary to fix the traction rope, the clamping member 532 moves down along the guide rod 533 until it contacts the surface of the traction rope. The position of the clamping member 532 after pressing is fixed by a threaded connection. The clamping member 532 is cylindrical. The smooth curved surface of the clamping member 532 can conform to the natural shape of the traction rope, increase the contact area with the traction rope, and thus achieve the effect of pressing and fixing the traction rope.

[0053] refer to Figure 6 and Figure 7 The rope end clamping structure 5 also includes a vertical clamping assembly 521. The traction rope extends from the pressing assembly 531 and enters the vertical clamping assembly 521, then combines with... Figure 2The traction rope's direction is adjusted from horizontal to vertical. The vertical clamping assembly 521 clamps the vertically oriented traction rope, thereby smoothly lifting the car 131. The vertical clamping assembly 521 includes a first vertical clamping plate 522 and a second vertical clamping plate 523. The first vertical clamping plate 522 and the second vertical clamping plate 523 are vertically arranged on the mounting frame 251. The first vertical clamping plate 522 is fixedly installed on the mounting frame 251, and the second vertical clamping plate 523 is bolted to the first vertical clamping plate. 522 is fixed.

The third clamping groove 5221 and the fourth clamping groove 5231 are positioned opposite each other. The first vertical clamping plate 522 and the second vertical clamping plate 523 are locked and fixed, so that the third clamping groove 5221 and the fourth clamping groove 5231 cooperate to clamp the traction rope.

[0054] refer to Figure 6 and Figure 7 An arc-shaped guide 541 is also fixedly installed on the mounting bracket 251. The arc-shaped guide 541 is located between the pressing component 531 and the vertical clamping component 521. The traction rope extending from the pressing component 531 enters the vertical clamping component 521 after being guided by the arc-shaped guide 541. The traction rope changes from horizontal to vertical more smoothly, reducing wear on the traction rope.

[0055] refer to Figure 1 and Figure 8 The main longitudinal beam 211 is also equipped with a pulley 7. After the traction rope passes around the car 131, it is guided by the pulley 7 and enters the main structure 111. A pressure plate assembly 6 is also fixedly installed on the main longitudinal beam 211. Figure 2 The pressure plate assembly 6 is located between the rope pulley 7 and the car 131. The pressure plate assembly 6 includes a first pressure plate 611 and a second pressure plate 621. The first pressure plate 611 and the second pressure plate 621 are vertically arranged on the main longitudinal beam 211. The first pressure plate 611 is fixedly installed on the main longitudinal beam 211. The second pressure plate 621 is bolted to the first pressure plate 611 and locked in place. The first pressure plate has a first pressure groove 612, which is located facing the second pressure groove 622. On one side, the second pressing plate has a second pressing groove 622, which is opposite to the first pressing groove 612. The first pressing groove 612 and the second pressing groove 622 are set as arc-shaped grooves that match the outer diameter of the traction rope. The first pressing plate 611 and the second pressing plate 621 are close to each other. The first pressing groove 612 and the second pressing groove 622 work together to fix the traction rope, improve the stability of the car 131 during the lifting process, and reduce the shaking of the car 131.

[0056] refer to Figure 2 and Figure 4The main structure 111 is located at the beginning of the traction rope. The main structure 111 includes a main body 112 and a main protective cover 113. The main protective cover 113 covers the outside of the main body 112 to protect the main body 112. The main body 112 includes a traction motor and a traction sheave. The traction motor drives the traction sheave to rotate. The traction rope is released or tightened as the traction sheave rotates, thereby driving the car 131 to run stably.

[0057] refer to Figure 2 and Figure 5 The seat structure 121 is located at the tail end of the traction rope. The seat structure 121 includes a wheel 122 and a seat protective cover 123. The seat protective cover 123 covers the wheel 122 to protect it. The traction rope extends out of the main structure 111 and wraps around the wheel 122. The seat structure 121 also includes a rope tail fixing component 124, which is fixedly installed on the telescopic beam 221. A counterweight 141 is provided between the wheel 122 and the rope tail fixing component 124. The traction rope extends out of the wheel 122 and pulls the counterweight 141. The tail end of the traction rope is fixed by the rope tail fixing component 124 to ensure that the car 131 and the counterweight 141 can operate stably.

[0058] refer to Figure 2 and Figure 9 The rope tail fixing assembly 124 includes a rope tail fixing member 1241, an elastic member 1242, and an arc-shaped winding member 1243. The rope tail fixing member 1241 is vertically fixed and installed on the telescopic beam 221. The elastic member 1242 is sleeved on the rope tail fixing member 1241 and includes a spring. One end of the elastic member 1242 abuts against the rope tail fixing member 1241 and the other end abuts against the telescopic beam 221. The arc-shaped winding member 1243 is fixedly installed at the bottom end of the rope tail fixing member 1241. The traction rope is wound and fixed on the arc-shaped winding member 1243. Under the action of the elastic member 1242, the traction rope pulls the rope tail fixing member 1241 to slide elastically vertically, making the lifting and lowering of the car 131 and the counterweight 141 more stable.

An adjusting groove 9131 is provided on the adjusting member 913. The fastener 914 slides in engagement with the adjusting groove 9131, and then... Figure 11The load-bearing beam 9 is locked and fixed to the main unit longitudinal beam 211 by pressing the end of the load-bearing beam 9 with fastener 914. The end of the telescopic beam 221 is provided with locking holes. The end of the load-bearing beam 9 and the end of the telescopic beam 221 can be locked and fixed by bolt structure, thereby strengthening the fixing effect of the load-bearing beam 9 and the main unit 1 of the computer room.

[0060] refer to Figure 11 and Figure 12 In the rear-mounted counterweight layout, two load-bearing beams 9 are arranged parallel to each other in the shaft, and the main body 1 of the computer room is vertically arranged in the shaft, with the load-bearing beams 9 located at the center of the main body 1, ensuring balanced force distribution. In the side-mounted counterweight layout, the two load-bearing beams 9 are installed at an angle in the shaft, and the main body 1 of the computer room is arranged horizontally in the shaft. In this case, the center of gravity of the main body 1 of the computer room will shift to the opposite side of the supporting structure 121. The second mounting plate 2411 abuts against the inner wall of the shaft, effectively preventing the main body 1 of the computer room from tilting and ensuring its overall positional stability. Furthermore, in both the rear-mounted and side-mounted counterweight layouts, the load-bearing beams 9 are located at the entrance of the shaft. The entrance area of ​​the shaft has ample operating space, allowing staff to access the load-bearing beams 9 without having to go deep into the shaft, greatly reducing the difficulty of removing the load-bearing beams 9 and minimizing the inconvenience caused by space constraints.

[0061] The implementation principle of this application embodiment is as follows: When it is necessary to fine-tune the installation direction of the main body 1 of the computer room, the contact load-bearing beam 9 is locked and fixed to the main body 1 of the computer room, driving the installation beam 2 to rotate. The installation beam 2 rotates around the bottom frame 3 to the target angle, changing the orientation of the main structure 111 and the opposite seat structure 121, flexibly adjusting the exit direction of the car 131. During the rotation, the load-bearing beam 9 continuously passes through the channel 311 to provide support, realizing convenient adjustment of the installation angle of the main body 1 of the computer room. The distance between the main longitudinal beam 211 and the telescopic beam 221 is adjusted by the locking component 4. The traction rope is released through the main structure 111. The first end of the traction rope is guided and fixed by the rope head clamp structure 5, and the tail end of the traction rope is guided by the opposite seat structure 121 and fixed by the rope tail fixing component 124, so that the car 131 is stably lifted with the cooperation of the counterweight 141.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
